Description

[Technical Field]

[0001] The present specification relates to a display device, and more particularly to a display device capable of generating sound by vibrating a display panel. [Background technology]

[0002] Display devices are installed in electronic products or home appliances such as televisions, monitors, laptops, smartphones, tablet computers, electronic pads, wearable devices, watch phones, portable information devices, navigation systems, or vehicle display devices, and are used as screens for displaying images.

[0003] The display device may include a display panel for displaying an image, and an audio device for outputting audio related to the image.

[0004] However, in general display devices, the sound output from the audio device travels behind or below the display panel, which causes interference between the sound reflected from the walls or floor, resulting in a deterioration in sound quality, making it difficult to accurately transmit sound and reducing the viewer's or user's sense of immersion. Summary of the Invention [Problem to be solved by the invention]

[0005] The inventors of the present specification recognized the problems of conventional display devices and conducted several experiments to find out whether sound can be directed forward when watching an image from the front of the display panel, thereby improving sound quality. Through these experiments, they invented a display device with a new structure that can generate sound that can travel forward from the display panel, thereby improving sound quality.

[0006] The problem to be solved by the embodiments of the present specification is to provide a display device including a sound generating module capable of generating sound that can travel in front of a display panel.

[0007] An object of the present invention is to provide a display device including a sound-generating module with a new structure that can improve assembly between the display module and the sound-generating module.

[0022] The advantages and features of the present specification, and methods for achieving them, will become clearer with reference to the following detailed description of the embodiments along with the accompanying drawings. However, the present specification is not limited to the embodiments disclosed below, and may be realized in various different forms. The embodiments are provided solely to complete the disclosure of the specification and to fully convey the scope of the invention to those skilled in the art to which the specification pertains. The specification is defined solely by the scope of the claims.

[0023] The implementation of the process steps and / or operations described herein is an example. However, the sequence of the process steps and / or operations is not limited to that described herein and may vary as known in the art, except for process steps and / or operations occurring in a particular order. Like reference numerals refer to like elements throughout. The names of the components used in the following description are selected solely for convenience in writing the specification and may differ from those used in the actual product.

[0024] The shapes, sizes, ratios, angles, numbers, etc. disclosed in the drawings for explaining the embodiments of this specification are illustrative only, and the present specification is not limited to the details shown in the drawings. The same reference numerals refer to the same components throughout the specification. Furthermore, in describing this specification, if a detailed description of related publicly known technology is deemed to unnecessarily obscure the gist of this specification, such detailed description will be omitted.

[0025] When the terms "comprise," "have," "consist of," etc. are used as mentioned herein, other parts may be added unless "only" is used. When an element is expressed in the singular, the plural is included unless otherwise expressly stated.

[0026] When interpreting elements, a margin of error should be included even if there is no other explicit statement. When describing a positional relationship, for example, when describing the positional relationship between two parts using "on," "over," "under," or "next," one or more other parts may be located between the two parts unless "just" or "directly" is used. When describing a temporal relationship, for example, when describing a temporal sequence using "after," "subsequent," "next," or "before," non-consecutive cases may also be included unless "just" or "immediately or directly" is used.

[0027] Although terms such as "first" and "second" are used to describe various components, these components are not limited by these terms. These terms are used only to distinguish one component from another. Therefore, the first component described below may be the second component within the technical concept of this specification, and similarly, the second component may also be the first component.

[0028] In describing components in this specification, terms such as first, second, A, B, (a), (b), etc. may be used. Such terms are used merely to distinguish the component from other components, and do not limit the nature, order, sequence, or number of the components. When a component is described as being "coupled," "coupled," or "connected" to another component, it should be understood that the component can be directly coupled or connected to the other component, but that there may also be other components "intervening" between components that can be indirectly coupled or connected unless otherwise explicitly stated.

[0029] "At least one" should be understood to include all combinations of one or more of the associated components. For example, the meaning of "at least one of the first, second, and third components" can include all combinations of two or more of the first, second, and third components, not just the first, second, or third component.

[0030] In the description of the embodiments, when a structure is described as being "on or above" or "under or below" another structure, this description should be interpreted to include cases where the structures contact each other and cases where a third structure is disposed between the structures. The size and thickness of each component shown in the figures are provided for convenience of description and are not limiting unless otherwise specified in the embodiments herein.

[0031] The features of the various embodiments of this specification may be partially or fully combined or combined with each other, and various technical interlocking and driving mechanisms may be possible, and each embodiment may be implemented independently of each other, or may be implemented together in a related relationship.

[0032] In this specification, the term "display device" may include a liquid crystal module (LCM) or an organic light emitting display module (OLED module) that includes a display panel and a driver for driving the display panel. In addition, in this specification, the term "display device" may also include a set electronic apparatus or set device (set apparatus) that includes a complete product or final product including an LCM or an OLED module, such as a laptop computer, television, computer monitor, automotive apparatus or other form of vehicle, or mobile electronic apparatus such as a smartphone or electronic pad.

[0033] Therefore, the display device in this specification may include the display device itself, such as an LCM or OLED module, as well as an application product including the LCM or OLED module or a set device for end users.

[0034] In another example, an LCM and OLED module consisting of a display panel and a driver may be referred to as a "display device," and a completed electronic device including the LCM and OLED module may be referred to as a "set device." For example, a display device may include a liquid crystal or organic light-emitting display panel and a source printed circuit board (source PCB) that is a controller for driving the display panel. The set device may include a display device and a set PCB or control PCB that is a set controller electrically connected to the source PCB and drives the entire set device.

[0035] The display panel used in the embodiments of the present specification may be any type of display panel, such as a liquid crystal display panel, an organic light emitting diode (OLED) display panel, or an electroluminescent display panel, and is not limited to the embodiments. For example, the display panel may be any display panel that can generate sound by vibrating with a sound generating module. Furthermore, the display panel used in the display device according to the embodiments of the present specification is not limited to any particular shape or size.

[0036] For example, if the display panel is a liquid crystal display panel, the display panel may include a plurality of gate lines, a plurality of data lines, and pixels (or sub-pixels) formed in pixel regions defined by the gate lines and the data lines. The display panel may also include an array substrate including thin film transistors (TFTs) that are switching elements for adjusting the light transmittance of each pixel, an upper substrate including color filters and / or a black matrix, and a liquid crystal layer formed between the array substrate and the upper substrate.

[0037] When the display panel is an organic light-emitting display panel, the display panel includes a plurality of gate lines, a plurality of data lines, and pixels (or sub-pixels) formed in pixel regions defined by the gate lines and the data lines. The display panel may also include an array substrate including thin film transistors (TFTs) for selectively applying voltages to each pixel, an organic light-emitting element layer on the array substrate, and an encapsulation substrate (or encapsulation substrate) disposed on the array substrate to cover the organic light-emitting element layer. The encapsulation substrate protects the TFTs and the organic light-emitting element layer from external impacts and prevents moisture and oxygen from penetrating the organic light-emitting element layer. The organic light-emitting element layer formed on the array substrate may be replaced with an inorganic light-emitting element layer, a quantum dot light-emitting element layer, or a micro light-emitting diode element.

[0038] The display device including the sound generating module in this specification can be applied to a vehicle as a user interface module, such as a central control panel in an automobile. For example, such a display panel can be installed between two front seat occupants so that vibrations of the display panel are propagated toward the interior of the vehicle. Therefore, the audio experience inside the vehicle can be improved compared to when speakers are only installed on the interior sides of the vehicle.

[0039] The following detailed description of the embodiments of the present specification will be given with reference to the accompanying drawings and examples. When assigning reference numerals to components in the accompanying drawings, identical components may be assigned the same numerals as much as possible, even if they are displayed in different drawings. Furthermore, the scales of the components shown in the accompanying drawings may be different from the actual scales for the sake of convenience, and are not limited to the scales shown in the drawings.

[0040] Fig. 1 is a diagram showing a display device according to an embodiment of the present specification, and Fig. 2 is a cross-sectional view taken along line II' shown in Fig. 1.

[0041] Referring to FIGS. 1 and 2, a display device according to an embodiment of the present specification may include a display module 100, a back cover 300, and at least one sound-generating module 500.

[0042] The display module 100 vibrates by driving at least one sound-generating module 500 while displaying an image, and outputs sound (PVS) (or panel vibration sound) directly in the front direction (or forward) (FD). Alternatively, the display module 100 can vibrate by driving at least one sound-generating module 500 while not displaying an image, and output sound (PVS) directly in the forward direction (FD). As a result, the display module 100 according to the present specification can both display an image and generate (or output) sound (PVS).

[0043] The display module 100 according to the embodiment of the present specification includes a display panel 110 for displaying an image. For example, the image may include an electronic image or a digital image.

[0044] The display panel 110 may be implemented as any type of display panel, such as an organic light emitting diode (OLED) display panel, a liquid crystal display panel, an electroluminescent display panel, a micro light emitting diode (LMD) display panel, or a quantum dot luminescent display panel. The display panel 110 vibrates in response to the vibration of the sound generating module 500 and directly outputs sound (PVS) to the front (FD). Thus, the display panel 110 may be a diaphragm or a speaker that directly generates sound (PVS). For example, when the display module 100 generates sound (PVS), the display module 100 may be a diaphragm, a panel speaker, or a flat speaker that directly generates sound (PVS).

[0045] According to some embodiments of the present specification, the display panel 110 includes pixel circuits disposed on a substrate (or base substrate), and a pixel array layer (or display unit) connected to the pixel circuits and having an anode electrode, a cathode electrode, and an organic light-emitting layer. The display panel 110 can display images in a top emission, bottom emission, or dual emission format depending on the structure of the pixel array layer. For example, the anode electrode may be a first electrode or a pixel electrode, and the terms are not limited thereto. The cathode electrode may be a second electrode or a common electrode, and the terms are not limited thereto.

[0046] The top emission method displays images by emitting light generated in the pixel array layer to the front (FD) of the substrate of the display panel 110, while the bottom emission method displays images by emitting light generated in the pixel array layer to the outside through the substrate.

[0047] The display module 100 according to some embodiments of the present disclosure may further include a functional film 130 disposed on the display panel 110 .

[0048] The functional film 130 may be attached to the display panel 110 using a transparent adhesive member. The adhesive member may include, but is not limited to, a pressure-sensitive adhesive (PSA), an optical clear adhesive (OCA), or an optical clear resin (OCR).

[0049] According to some embodiments of the present specification, the functional film 130 may include an anti-reflection layer (or an anti-reflection film) for preventing reflection of external light to improve outdoor visibility and contrast ratio of an image displayed on the display panel 110. For example, the anti-reflection layer may include a circular polarization layer (or a circular polarization film) for blocking reflected light, which is external light reflected by thin film transistors and / or lines arranged on the pixel array layer of the display panel 110, from traveling to the outside.

[0050] According to some embodiments of the present specification, the functional film 130 may further include a light path control layer (or light path control film) that controls the path of light exiting from the pixel array layer of the display panel 110 to the outside. The light path control layer may include a structure in which high refractive index layers and low refractive index layers are alternately stacked, thereby changing the path of light incident from the pixel array layer and minimizing the color shift phenomenon due to viewing angles. For example, the low refractive index layer may be disposed on the top layer of the light path control layer.

[0051] The display module 100 according to some embodiments of the present disclosure may further include a touch electrode unit for a user interface using a user's touch. The touch electrode unit may be interposed between the display panel 110 and the functional film 130 or may be built into the display panel 110 based on an in-cell touch method. For example, the in-cell touch touch electrode unit may include a mutual capacitance type touch electrode or a self-capacitance type touch electrode.

[0052] The rear cover 300 is disposed on the rear surface (rear surface) of the display module 100. The rear cover 300 can support or fix the sound-generating module 500.

[0053] According to some embodiments of the present specification, the rear cover 300 covers the rear surface of the display module 100 and the sound-generating module 500. The rear cover 300 may be expressed as a support member, a housing, a system cover, a set cover, a back cover, a cover bottom, a rear frame, a chassis, or the like, and is not limited to these terms. Furthermore, the rear surface of the display module 100 may be expressed as one surface, a first surface, a rear surface, a bottom surface, or the like, and is not limited to these terms.

[0054] According to some embodiments herein, the back cover 300 may include a first back cover 310 and a second back cover 350 .

[0055] The first rear cover 310 is disposed on the rear surface of the display module 100 and covers the rear surface of the display module 100, for example, the display panel 110. The first rear cover 310 is separated from the rearmost surface of the display module 100 with a gap space (GS) therebetween. The first rear cover 310 can support or fix the sound-generating module 500. The first rear cover 310 can protect the rear surface of the display module 100 from external impact. The first rear cover 310 can also serve as a heat sink for dissipating heat generated from the display module 100.

[0056] According to some embodiments of the present specification, the first rear cover 310 may be a plate-like member that covers the rearmost surface of the display module 100, for example, the entire rear surface of the display panel 110. For example, the edges or corners of the first rear cover 310 may have a sloped or curved shape through a chamfering process or a corner rounding process.

[0057] According to some embodiments of the present specification, the first rear cover 310 according to one embodiment of the present specification may be made of glass, metal, or plastic. For example, the first rear cover 310 made of glass may be made of sapphire glass or Gorilla Glass, or may have a laminated structure (or bonded structure) of these. For example, the first rear cover 310 made of metal may be made of aluminum, aluminum alloy, magnesium alloy, iron-nickel alloy, or stainless steel, or may have an alloy or bonded structure of these.

[0058] The second rear cover 350 is disposed on the rear surface of the first rear cover 310 and covers the rear surface of the first rear cover 310. According to some embodiments of the present specification, the second rear cover 350 may be a plate-like member that covers the entire rear surface of the first rear cover 310. For example, the edges or corners of the second rear cover 350 may have a beveled or curved shape by a chamfering process or a corner rounding process.

[0059] According to some embodiments of the present specification, the second rear cover 350 may be made of any one of glass, metal, and plastic materials, or may be made of a different material from the first rear cover 310. For example, the second rear cover 350 may be made of glass, and the first rear cover 310 may be made of a metal material such as aluminum (Al) that has excellent thermal conductivity. For example, the appearance design of the display device can be improved by using the second rear cover 350 made of glass and arranged at the rearmost part, and the rear of the display device can be made of a mirror-like first rear cover 310 made of metal.

[0060] According to some embodiments of the present specification, the second rear cover 350 according to an example of the present specification may have the same thickness as the first rear cover 310 within a manufacturing process tolerance, or may have a thickness relatively thinner than the first rear cover 310. For example, the first rear cover 310 may have a thickness relatively thicker than the second rear cover 350 in order to more stably support the sound generating module 500 and reduce the weight of the display device.

[0061] According to some embodiments of the present disclosure, the first rear cover 310 and the second rear cover 350 may be joined or connected to each other via a cover connecting member 330. For example, the cover connecting member 330 may be an adhesive resin, double-sided tape, or a double-sided adhesive foam pad, and may have elasticity for shock absorption.

[0062] According to some embodiments of the present disclosure, the cover connecting member 330 may be interposed over the entire area between the first rear cover 310 and the second rear cover 350 .

[0063] According to some embodiments of the present specification, the cover connecting member 330 may be formed in a mesh structure with an air gap between the first rear cover 310 and the second rear cover 350. For example, part of the air gap may be used as an arrangement area for a cable or signal transmission member connected to the sound-generating module 500.

[0064] At least one sound generating module 500 can use the display module 100, for example the display panel 110, as a diaphragm to generate sound (PVS).

[0065] A display device according to some embodiments of the present specification may include one sound-generating module disposed in the center (or central region) of the rear surface of the display module 100. For example, the one sound-generating module vibrates the center of the rear surface of the display module 100 to generate sound (PVS) due to vibration of the display module 100.

[0066] According to another embodiment of the present specification, a display device may include a first sound-generating module 500-1 arranged in a first region (or left region) of the display module 100 and a second sound-generating module 500-2 arranged in a second region (or right region) of the display module 100, based on the center of the rear surface of the display module 100. For example, the first sound-generating module 500-1 vibrates a first rear region of the display module 100 to generate sound (PVS) due to vibration of the first region of the display module 100. The second sound-generating module 500-2 vibrates a second region of the display module 100 to generate sound (PVS) due to vibration of the second region of the display module 100. Such a display device according to another embodiment of the present specification may output stereo sound in a two-channel mode by separating left and right sounds through the first and second sound-generating modules 500-1 and 500-2. For example, the first sound-generating module 500-1 may be configured to output left sound, and the second sound-generating module 500-2 may be configured to output right sound.

[0067] According to some embodiments of the present disclosure, at least one sound-generating module 500 is disposed between the display module 100 and the rear cover 300 and vibrates the display module 100 to generate sound (PVS). The rear surface of the at least one sound-generating module 500 is covered by the rear cover 300 and is therefore concealed and not directly exposed to the outermost rear surface of the display device. As a result, the display device according to the embodiments of the present disclosure may have a clean back design in which the rear surface or a portion of the at least one sound-generating module 500 is not exposed or is not visible to the user, as the rear surface of the at least one sound-generating module 500 is covered by the rear cover 300, thereby improving the exterior design of the rear surface.

[0068] The at least one sound-generating module 500 according to some embodiments of the present disclosure may be a single structure or a single component, in which the module structure 510 disposed on the rear cover 300 and the vibration device 530 disposed on the module structure 510 for vibrating the display module 100 are modularized into a single component. For example, the at least one sound-generating module 500 may be mounted or positioned in the gap space (GS) between the display module 100 and the rear cover 300 by a relatively simple parts mounting (or batching) process during the display device assembly process, after the module structure 510 and the vibration device 530 are manufactured as a single component or a finished product, through a modularization process (or assembly process) rather than a display device assembly process. As a result, the display device according to the embodiments of the present disclosure may improve the assemblability of the at least one sound-generating module 500 during the module assembly process, thereby increasing production yields.

[0069] At least one sound-generating module 500 according to the embodiments of the present specification can directly or indirectly vibrate the display module 100. For example, the at least one sound-generating module 500 can be directly connected to the display panel 110 to directly vibrate the display panel 110. As another example, the at least one sound-generating module 500 can indirectly vibrate the display panel 110 via a vibration transmission member directly connected to the display panel 110. For example, the vibration transmission member may be implemented in the corresponding sound-generating module 500 or in the display module 100. For example, the vibration transmission member implemented in the at least one sound-generating module 500 may be a vibration transmission plate (or vibration transmission sheet) in contact with (or coupled to) the display module 100. Furthermore, the vibration transmission member implemented in the display module 100 may be a backlight module disposed on the rear surface of the display panel 110, or a vibration transmission plate (or heat dissipation plate) coupled to (or attached to) the rear surface of the display panel 110.

[0070] The display device according to an embodiment of the present disclosure may further include a middle frame 700 .

[0071] The middle frame 700 is disposed between the rear edge of the display module 100 and the front edge of the rear cover 300. The middle frame 700 supports the respective edges of the display module 100 and the rear cover 300 and surrounds the respective sides of the display module 100 and the rear cover 300. The middle frame 700 provides a gap space (GS) between the display module 100 and the rear cover 300. The gap space (GS) may be expressed by an air gap, a vibration space, an arrangement space for the sound-generating module, or the like, and is not limited to any particular term.

[0072] According to some embodiments of the present specification, the middle frame 700 is connected or coupled to a rear edge of the display module 100 via a first adhesive member 7011, and is connected or coupled to a front edge of the rear cover 300 via a second adhesive member 7013. The front face of the rear cover 300 may be referred to as the other face, second face, top face, front face, or the like, and is not limited to these terms. The middle frame 700 may be referred to as a middle cabinet, middle cover, middle chassis, or the like, and is not limited to these terms.

[0073] According to some embodiments of the present disclosure, the middle frame 700 may be made of a metal material or a plastic material. For example, the middle frame 700 may be made of a metal material to improve the side appearance design of the display device and protect the side of the display device.

[0074] The middle frame 700 according to some embodiments of the present disclosure may include a support portion 7110 and a side wall portion 7130. The support portion 7110 may be a first portion, and the side wall portion 7130 may be a second portion, and these terms are not intended to be limiting.

[0075] The support 7110 is interposed between the rear edge of the display module 100 and the front edge of the rear cover 300, thereby providing a gap space (GS) between the display module 100 and the rear cover 300. The front surface of the support 7110 is coupled to the rear edge of the display module 100 via a first adhesive member 7011, and the rear surface of the support 7110 is coupled to the front edge of the rear cover 300 via a second adhesive member 7013. The support 7110 may have a thickness (or height) corresponding to the overall module thickness of the sound-generating module 500. For example, the thickness of the support 7110 may be set or varied depending on the module thickness of the sound-generating module 500 disposed between the display module 100 and the rear cover 300, the thickness of the first adhesive member 7011, and the thickness of the second adhesive member 7013.

[0076] According to some embodiments of the present specification, the support portion 7110 has a single rectangular (e.g., square) frame structure, but is not necessarily limited thereto. For example, the support portion 7110 may have the form of a plurality of dividing bars interposed between the rear edge of the display module 100 and the front edge of the rear cover 300.

[0077] The first adhesive member 7011 is disposed between the rear edge of the display module 100 and the front surface of the support 7110. For example, the first adhesive member 7011 may be, but is not limited to, an adhesive resin, double-sided tape, or a double-sided adhesive foam pad.

[0078] The second adhesive member 7013 is disposed between the front edge of the rear cover 300 and the rear surface of the support portion 7110. For example, the second adhesive member 7013 may be, but is not limited to, adhesive resin, double-sided tape, or a double-sided adhesive foam pad. The second adhesive member 7013 may be made of a different material from the first adhesive member 7011.

[0079] The side wall 7130 is perpendicularly coupled to the outer surface of the support 7110 in parallel with the thickness direction (Z) of the display device. The side wall 7130 surrounds both the outer surface (or outer wall) of the display module 100 and the outer surface (or outer wall) of the rear cover 300, thereby protecting the outer surfaces of the display module 100 and the rear cover 300 and improving the outer design of the side of the display device. The middle frame 700 according to some embodiments of the present specification may have a frame structure with a cross-sectional structure in the shape of a "┣" as the support 7110 and the side wall 7130 are coupled to each other to form a single housing.

[0080] The display device according to the embodiment of the present specification may include an adhesive member instead of the middle frame 700.

[0081] The adhesive member is interposed between the rear edge of the display module 100 and the front edge of the rear cover 300, thereby providing a gap space (GS) between the display module 100 and the rear cover 300. The adhesive member may have a thickness (or height) corresponding to the overall module thickness of the sound-generating module 500. For example, the thickness of the adhesive member may be set or varied depending on the module thickness of the sound-generating module 500 disposed between the display module 100 and the rear cover 300. Such an adhesive member may function the same as the support portion 7110 of the middle frame 700.

[0082] When the display device includes an adhesive member instead of the middle frame 700, the rear cover 300 includes a side wall cover portion that surrounds both the outer surface (or outer wall) of the display module 100 and the outer surface (or outer wall) of the rear cover 300 and the outer surface (or outer wall) of the adhesive member.

[0083] The side wall cover portion extends from the end of the second rear cover 350 and is bent perpendicularly to be parallel to the thickness direction (Z) of the display device. According to some embodiments of the present specification, the side wall cover portion has a single side wall structure or a hamming structure. A hamming structure refers to a structure in which the ends of a member are bent into a curved shape and overlap each other or are spaced apart parallel to each other. For example, a side wall cover portion having a hamming structure may include a first side wall extending from the end of the second rear cover 350 and bent to be parallel to the thickness direction (Z) of the display device, and a second side wall extending from the end of the first side wall and bent to be parallel to the first side wall. The second side wall may be disposed between the outer surface of the display module 100 and the first side wall. For example, the second side wall may not be exposed to the outermost side of the display device but may be covered by the first side wall, improving the side outline design of the display device.

[0084] In the display device according to the examples of this specification, the display module 100 may further include a heat diffusion member 150 .

[0085] The heat diffusion member 150 may be disposed between the vibration device 530 of the sound-generating module 500 and the display module 100. The heat diffusion member 150 according to the examples of this specification may be attached to the rear surface of the display module 100 so as to overlap the sound-generating module 500, and may be coupled or connected to the vibration device 530 of the sound-generating module 500. The heat diffusion member 150 is disposed on the rear surface of the display module 100 so as to overlap the vibration device 530, and diffuses heat generated when the vibration device 530 is driven toward the display module 100, thereby preventing a deterioration in performance of the vibration device 530 due to heat. In addition, the heat diffusion member 150 is relatively larger than the vibration device 530, with the center of the vibration device 530 as the center, and thereby diffuses the heat generated when the sound generating module 500 is driven over a wide area. This prevents heat from being transferred intensively to a localized area of ​​the sound generating module 500 and the overlapping display module 100, thereby preventing or minimizing local brightness unevenness of the display module 100.

[0086] According to some examples in this specification, the heat diffusion member 150 may be formed of a metal material with high thermal conductivity, such as, but not limited to, aluminum (Al), copper (Cu), silver (Ag), or magnesium (Mg), or an alloy thereof. The heat diffusion member 150 may be expressed by other terms, such as, but not limited to, a heat diffusion sheet, a heat diffusion layer, a heat diffusion plate, a heat sink, a heat dissipation sheet, a heat dissipation layer, or a heat dissipation plate.

[0087] Therefore, the display device according to the embodiments of the present specification can output sound (PVS) forward (FD) by vibrating the display module 100, for example, the display panel 110, using the sound generating module 500 arranged between the display module 100 and the rear cover 300, thereby improving the sense of immersion of the viewer watching the image on the display device.

[0088] In addition, the display device according to the embodiments of the present specification generates sound (PVS) by vibration of the display panel 110, eliminating the need for a separate speaker, thereby improving the freedom of design of the set device and speaker placement.

[0089] In addition, in the display device according to the embodiments of the present specification, the sound-generating module 500 is disposed in the gap space (GS) between the display module 100 and the rear cover 300, and the rear surface of the sound-generating module 500 is covered by the rear cover 300, so that the rear surface or a part of the sound-generating module 500 is not exposed or is not visible to the user, thereby providing a clean back design, which can improve the rear exterior design of the display device.

[0090] In addition, in the display device according to the embodiments of the present specification, the module structure 510 and the vibration device 530 of the sound-generating module 500 are modularized into a single component and are mounted in the gap space (GS) between the display module 100 and the rear cover 300 through a relatively simple component mounting process, thereby improving the assembly of the sound-generating module 500 during the display device assembly process, thereby increasing production yield.

[0091] 3A to 3E are diagrams illustrating a sound generating module according to one embodiment of the present specification.

[0092] 2 to 3E, a sound-generating module 500 according to an embodiment of the present disclosure includes a module structure 510 and a vibration device 530. As shown in FIG.

[0093] The module structure 510 may be disposed on the rear cover 300. For example, the module structure 510 may be disposed on the rear cover 300 to fix or support the vibration device 530. According to some examples in this specification, the module structure 510 may be a metal plate made of a metal material and having a flat plate shape. The module structure 510 may be expressed as a plate-shaped mechanism, a base structure, a module support frame, a module support plate, or the like, and is not limited to these terms.

[0094] The module structure 510 may be disposed on or fixed to the rear cover 300 via the first member 410 (or a module fixing member). The rear surface of the module structure 510 is covered by the rear cover 300 and is therefore concealed and not directly exposed to the outermost rear surface of the display device. For example, the rear surface of the module structure 510 is completely covered by the rear cover 300 and is therefore concealed and not directly exposed to the outermost rear surface of the display device.

[0095] According to some examples herein, the first member 410 may be a double-sided adhesive member interposed between the module structure 510 and the rear cover 300. The double-sided adhesive member may be, but is not limited to, a double-sided tape or a double-sided foam tape. One side (or front side) of the first member 410 is bonded or disposed on the rear side of the module structure 510, and the other side (or rear side) of the first member 410 is disposed or fixed to the front side of the first rear cover 310, for example, the rear cover 300. For example, the other side of the first member 410 may be fixed or disposed on the front side of the first rear cover 310 with the lower protective sheet peeled off.

[0096] According to some examples in this specification, the first member 410 may be coupled (or modularized) to the rearmost surface of the modularized sound-generating module 500 as a single component for ease of assembly between the sound-generating module 500 and the display module 100, and may be protected by a bottom protective sheet. For example, the bottom protective sheet may be expressed as a bottom release sheet or a bottom liner, and the terms are not limited thereto.

[0097] According to some examples herein, the double-sided adhesive member of the first member 410 may further include a heat transfer material. The heat transfer material quickly transfers heat generated from the sound-generating module 500 toward the rear cover 300, thereby dissipating the heat from the sound-generating module 500 toward the rear cover 300. This prevents or minimizes local brightness unevenness of the display module 100 caused by heat generated when the sound-generating module 500 is driven being locally transferred to an area of ​​the display module 100 that overlaps with the sound-generating module 500. According to some examples herein, the heat transfer material may include, but is not limited to, conductive particles or a conductive layer. For example, a double-sided adhesive member including a heat transfer material may be referred to as a thermally conductive tape or a heat dissipation tape, and the terms are not limited thereto.

[0098] The vibration device 530 is disposed in the module structure 510 to vibrate the display module 100. For example, the vibration device 530 may be disposed in the module structure 510 to vibrate the display panel 110. The vibration device 530 may be fixed to or integrated with the module structure 510 via the module integration member 520.

[0099] The vibration device 530 may include any acoustic device or vibration generating device that can vibrate the display module 100 with an electrical signal. For example, the vibration device 530 may be configured to vibrate the display module 100 with a current (or voice current) applied based on Fleming's left hand rule. The vibration device 530 may be expressed as an acoustic generating unit, and the acoustic generating module may be expressed as a vibration generating module, actuator, exciter, transducer, or the like, and the terms are not limited thereto.

[0100] The vibration device 530 includes an actuator (or exciter) arranged to contact the rear surface of the display module 100. For example, the vibration device 530 including the actuator may include a base plate 531, a magnet 532, a center pole 533, a bobbin 534, a coil 535, an edge frame 536, and a damper 537. For example, the vibration device 530 may be a vibration device including a voice coil, and is not limited to the term.

[0101] The base plate 531 is disposed on or fixed to the module structure 510 and may be the main body of the vibration device 530. The base plate 531 may support the magnet 532, the center pole 533, and the edge frame 536. The base plate 531 may be made of a magnetic metal material such as iron (Fe), and may be referred to as a lower plate, a base frame, a yoke, or the like, and is not limited to these terms.

[0102] The base plate 531 includes a groove that accommodates the magnet 532 and the bobbin 534. For example, the groove may be recessed from the upper surface of the base plate 531 to have a circular shape.

[0103] The base plate 531 may be disposed on or integrated into the module structure 510 via the module integration member 520 .

[0104] The module integrating member 520 may be an adhesive member. The adhesive member is disposed between the extension portion (or fixing portion) 531a of the base plate 531 and the module structure 510, thereby attaching the base plate 531 to the module structure 510. The module integrating member 520 made of an adhesive member may be, but is not necessarily limited to, an adhesive agent or double-sided tape.

[0105] According to another embodiment of the present disclosure, the module integration member 520 may be a plurality of screws that pass through the extensions 531 a of the base plate 531 and fasten to the module structure 510, thereby positioning the base plate 531 on the module structure 510.

[0106] According to other embodiments of the present disclosure, the module integration member 520 may be a bolt and a nut. The nut is disposed on or fixed to the module structure 510 overlapping the extension 531a of the base plate 531. The bolt passes through the extension 531a of the base plate 531 and fastens to the nut. According to some examples of the present disclosure, the nut may be, but is not limited to, a self-clinching nut disposed on the module structure 510. The self-clinching nut may be a PEM nut.

[0107] The magnet 532, the center pole 533, the bobbin 534, and the coil 535 can be expressed as a magnetic circuit unit or a magnetic vibration unit that is installed on the base plate 531 and vibrates the display module 100.

[0108] The magnetic circuit unit according to some examples herein may have an external magnetic type or dynamic type structure in which the magnet 532 is disposed outside the coil 535, or an internal magnetic type or micro type structure in which the magnet 532 is disposed inside the coil 535. A vibration device 530 including a magnetic circuit unit having an internal magnetic type structure has the advantage of having small leakage magnetic flux and a small overall size. The vibration device 530 according to some examples herein may have an external magnetic type or internal magnetic type structure, and the following description will be made assuming that it has an internal magnetic type structure.

[0109] According to some examples herein, the magnet 532 is accommodated or inserted into a groove in the base plate 531. The magnet 532 may be a cylindrical permanent magnet that can be accommodated or inserted into a bobbin 534. According to some examples herein, the magnet 532 may be a sintered magnet such as barium ferrite, and the material may be ferric oxide (Fe2O3), barium carbonate (BaCO3), neodymium magnet, or strontium ferrite (Fe) with improved magnetic properties. 12 O 19 The magnets may include one or more of alloy cast magnets of Sr, aluminum (Al), nickel (Ni), cobalt (Co), etc. For example, the neodymium magnet may be, but is not limited to, neodymium-iron-boron (Nd-Fe-B).

[0110] According to some examples herein, the bobbin 534 is disposed on the base plate 531 so as to surround the magnet 532. The bobbin 534 may have a circular or elliptical shape, but is not limited thereto. The oval shape may include, but is not limited to, an elliptical shape, a rectangular shape with rounded corners, or a non-circular curved shape having a width different from its height. For example, the elliptical bobbin 534 may have a ratio of the major diameter to the minor diameter of 1.3:1 to 2:1. Such an elliptical bobbin 534 may improve the acoustics in the high frequency range compared to a circular shape and may have excellent heat dissipation properties due to less heat generation due to vibration.

[0111] The coil 535 according to some examples of this specification is wound around the outer periphery of the bobbin 534 and is supplied with an external current (or voice current) for generating sound. The coil 535 moves up and down together with the bobbin 534. The coil 535 may be expressed as a voice coil, etc. When a current is applied to the coil 535, the entire bobbin 534 moves up and down according to Fleming's left-hand rule based on the magnetic field formed around the coil 535 and the external magnetic field formed around the magnet 532. The up and down movement (or vibration) of the bobbin 534 causes the display module 100 to vibrate, generating sound (PVS) or sound waves.

[0112] According to some examples herein, when the coil 535 is wound around the outer periphery of the bobbin 534, heat generated in the coil 535 is transferred to the bobbin 534. To reduce image quality defects that may affect the display panel 110 due to the heat from the bobbin 534, the coil 535 may be made of a material with relatively excellent heat dissipation properties. Furthermore, since the bobbin 534 vibrates up and down, biased vibrations due to the up and down vibrations occur. The biased vibrations of the bobbin 534 may be affected by the weight of the bobbin 534, which in turn is affected by the weight of the coil 535. Thus, if the weight of the coil 535 is reduced, the biased vibrations of the bobbin 534 can be reduced. Therefore, considering the heat transferred to the bobbin 534 and the biased vibrations of the bobbin 534, the coil 535 may be made of aluminum, which has better thermal conductivity and relatively better heat dissipation properties than copper, a common coil material, and is relatively lighter than copper.

[0113] Furthermore, since aluminum forms an oxide film in air and is difficult to solder during the manufacture of the vibration device 530, the coil 535 according to the example of this specification may include an aluminum layer (or a first metal layer) for heat dissipation and a metal outer layer (or a second metal layer) surrounding the aluminum layer. For example, the metal outer layer may include any of copper (Cu), silver (Ag), and gold (Au). For example, the coil 535 may be copper-clad aluminum (copper clad aluminum wire). Because the metal outer layer is formed as a thin film on the outside of the first metal layer, it may not significantly affect the weight of the coil 535. The weight of the coil 535 according to the example of this specification may be approximately 60% lighter than a coil made of only copper material or copper wire.

[0114] According to some examples herein, the bobbin 534 may be a structure formed of a material such as processed pulp or paper, aluminum, magnesium or alloys thereof, synthetic resin such as polyimide, etc. For example, the bobbin 534 may be made of a polyimide film, which has relatively good heat dissipation properties and is relatively light, in order to prevent localized image quality defects of the display panel 110 due to heat generated by the coil 535.

[0115] Polyimide film has properties that remain unchanged over a wide temperature range, from -273°C to 400°C, and is characterized by heat resistance, electrical insulation, flexibility, and non-flammability. Furthermore, polyimide film has excellent thermal and mechanical strength, which can improve the reliability of the bobbin 534, and its excellent heat dissipation properties can reduce heat generation due to vibration of the bobbin 534. For example, the polyimide film can be KAPTON, which can be a condensation product of pyromellitic dianhydride and 4,4'-oxydianiline.

[0116] The center pole 533 is accommodated or inserted into the bobbin 534 to guide the lifting and lowering of the bobbin 534. For example, the center pole 533 is accommodated or inserted inside the bobbin 534, so that the outer periphery of the center pole 533 is surrounded by the bobbin 534. The center pole 533 can be expressed as a lifting guide or pole pieces, and is not limited to these terms.

[0117] The edge frame 536 is installed at the front edge of the base plate 531 and supports the damper 537. According to some examples herein, the edge frame 536 may be formed at a certain height at the front edge of the base plate 531 so as to have the same shape as the bobbin 534. According to other examples herein, the edge frame 536 may include a hollow portion formed at a certain height at the front edge of the base plate 531 and having the same shape as the bobbin 534.

[0118] The damper 537 may be disposed between or coupled to the edge frame 536 and the magnetic circuit unit. For example, the damper 537 may be coupled between the edge frame 536 and the bobbin 534. The damper 537 may be expressed by other terms such as a spider, a suspension, or an edge, and is not limited to these terms.

[0119] According to some examples herein, one end (or a portion) of the damper 537 may be connected to the edge frame 536, and the other end (or another portion) of the damper 537 may be connected to the upper outer surface of the bobbin 534. The damper 537 has a bellows structure between one end and the other end, and adjusts the vibration of the bobbin 534 by contracting and relaxing according to the up and down movement of the bobbin 534. The damper 537 is connected between the bobbin 534 and the edge frame 536, and limits the vibration distance of the bobbin 534 through its restoring force. For example, if the bobbin 534 vibrates more than a certain distance or less than a certain distance, the bobbin 534 can return to its original position due to the restoring force of the damper 537.

[0120] Since the vibration device 530 is interposed between the display module 100 and the rear cover 300, it must have a relatively thin thickness in order to make the display device thin or slim. Therefore, if the height (or thickness) of the bobbin 534 is reduced, there is a problem of reduced sound pressure. Therefore, in order to solve the problem of reduced sound pressure caused by a reduced height of the bobbin 534, the inventors of the present specification designed a structure that increases the area of ​​the damper 537 arranged around the bobbin 534. They recognized that if the area of ​​the damper 537 is increased, the arrangement space for the wiring that applies current to the coil 535 becomes narrow, causing interference between the wiring and the damper 537. Therefore, through several experiments, they constructed the damper 537 from a conductor so that the damper 537 can also function as a wiring.

[0121] According to some examples herein, the damper 537 may include a metal material electrically connected to the coil 535. For example, the damper 537 may be made of, but is not limited to, stainless steel or copper (Cu).

[0122] The vibration device 530 according to some examples herein may further include a bobbin protection member 538.

[0123] The bobbin protection member 538 is disposed on the front surface (or tip) of the bobbin 534 and transmits the elevation (or vibration) of the bobbin 534 to the rear surface of the display module 100. The bobbin protection member 538 according to some examples herein may have a ring shape attached to the front surface of the bobbin 534, a disk shape covering the entire front surface of the bobbin 534, or a cap shape covering the front surface and upper outer surface of the bobbin 534. The bobbin protection member 538 may be expressed as a bobbin ring or the like, and is not limited to the term.

[0124] The sound generating module 500 according to an embodiment of the present disclosure may further include a connecting member 550 .

[0125] The connecting member 550 is interposed between the modular structure 510 and the display module 100. According to some examples herein, the connecting member 550 may be interposed between the front end of the modular structure 510 and the rear end of the display module 100. For example, the connecting member 550 may be, but is not limited to, double-sided tape or double-sided foam tape. The connecting member 550 may provide a vibration space surrounding the vibration device 530 between the modular structure 510 and the display module 100. The vibration space may also be expressed as a sound pressure space, a sound body, a resonating section, a resonance tube, or a resonating section, and is not limited to these terms.

[0126] The sound-generating module 500 according to the embodiment of the present specification may further include a vibration transmission member 570 .

[0127] The vibration transmission member 570 is connected or coupled to the connecting member 550 and the vibration device 530 , respectively, and vibrates with the vibration of the vibration device 530 , and can transmit the vibration of the vibration device 530 to the display module 100 .

[0128] According to some examples herein, the rear end or rear peripheral portion of the vibration transmission member 570 may be connected or coupled by a connecting member 550, and the rear central portion of the vibration transmission member 570 may be coupled to the front of the bobbin 534 of the vibration device 530 or to the bobbin protection member 538 of the vibration device 530.

[0129] According to some examples of the present specification, the vibration transmission member 570 may be made of one or more of aluminum (Al), magnesium (Mg) alloy, magnesium-lithium (Mg-Li) alloy, and aluminum (Al) alloy, but is not limited thereto. For example, a magnesium alloy may contain aluminum, zinc (Zn), and / or manganese (Mn). Magnesium alloy is the lightest metal material that can be used for a speaker diaphragm. It has relatively high specific rigidity (strength / specific gravity), relatively high vibration damping capacity (the ability to absorb vibrations and gradually reduce them), and excellent dimensional stability over temperature and time.

[0130] According to some examples herein, the front surface of the vibration transmission member 570 can be coupled or connected to the rear surface of the display module 100 via the second member 430 (or a module adhesive member).

[0131] The second member 430 may be a double-sided adhesive member interposed between the display module 100 and the vibration transmission member 570. The double-sided adhesive member may be, but is not limited to, a double-sided tape or a double-sided foam tape. One surface (or front surface) of the second member 430 is disposed on or coupled to the rear surface of the display module 100, and the other surface (or rear surface) of the second member 430 is disposed on or coupled to the front surface of the vibration transmission member 570. For example, one surface of the second member 430 may be disposed on or fixed to the rear surface of the display module 100 with the upper protective sheet peeled off.

[0132] According to some examples in this specification, the second member 430 may be attached (or modularized) to the top surface of the modularized sound-generating module 500 as a single component for ease of assembly between the sound-generating module 500 and the display module 100, and may be protected by an upper protective sheet. For example, the upper protective sheet may be expressed as an upper release sheet or a top liner, but is not limited to these terms.

[0133] For example, the vibration transmission member 570 and the second member 430 may be omitted altogether. For example, the sound-generating module 500 may include an upper protective sheet coupled to or connected to the connecting member 550 and the vibrating device 530, respectively. The upper protective sheet is coupled to or connected to the connecting member 550 and the vibrating device 530, respectively, and covers the entire front surface of the sound-generating module 500. This prevents the vibrating device 530 and the connecting member 550 of the sound-generating module 500 from being exposed to the outside during transportation after the modularization process of the sound-generating module 500 modularized into a single component, and prevents foreign matter such as dust from penetrating into the sound-generating module 500. Such an upper protective sheet may be peeled off from the sound-generating module 500 immediately before the assembly process between the sound-generating module 500 and the display module 100.

[0134] Therefore, the sound generating module 500 according to an embodiment of the present specification, in which the module structure 510 and the vibration device 530 are modularized into a single component and interposed between the display module 100 and the rear cover 300, uses the display module 100 as a diaphragm to output sound (PVS) due to the vibration of the display panel 110, and is not exposed on the outermost rear surface of the display device, thereby improving the rear appearance design of the display device.

[0135] 3B and 3C, an adhesive member 522 may be disposed between the vibration device 530 and the module structure 510. The adhesive member 522 may be one or more of, but is not limited to, double-sided tape, double-sided foam tape, double-sided padding, double-sided foam padding, and glue. When the adhesive member 522 is used, the assembly process may be simplified compared to screws or nuts and bolts, and a slimmer vibration device may be provided because holes or plate extensions for fastening with screws or nuts and bolts are not required. The description of the vibration device is the same as that described with reference to FIG. 3A, so a description thereof will be omitted here.

[0136] 3B, the vibration device 530 may be arranged asymmetrically. When arranged asymmetrically, the deep sound phenomenon at a specific frequency can be improved. For example, when standing waves are generated from above, below, left, and right with respect to the vibration device 530, the deep sound phenomenon occurs from above, below, left, and right. However, when arranged asymmetrically, the phenomenon of standing waves simultaneously occurring from above, below, left, and right can be reduced. This can improve the deep sound phenomenon, thereby further improving the acoustic characteristics.

[0137] 3D and 3E, the rear cover 300 may include a first rear cover 310 and a second rear cover 350. The first rear cover 310 and the second rear cover 350 are the same as those described in FIG. 2, and therefore will not be described here.

[0138] Referring to FIG. 3D , the vibration device 530 may be housed between the first rear cover 310 and the first rear cover 310. For example, the vibration device 530 may be disposed in a portion of the first rear cover 310 from which a portion has been removed. The first rear cover 310 and the vibration device 530 may be attached by an adhesive member 522. The adhesive member 522 may be disposed between the vibration device 530 and the second rear cover 350. As another example, the adhesive member 522 may be further disposed between the vibration device 530 and the first rear cover 310. For example, the adhesive member 522 may be further disposed between the extension portion 531a of the base plate 531 and the first rear cover 310. The adhesive member 522 may be one or more of, but is not limited to, double-sided tape, double-sided foam tape, double-sided padding, double-sided foam padding, and glue. By removing a portion of the first rear cover 310 and disposing the vibration device 530 in the removed area of ​​the first rear cover 310, the thickness of the vibration device 530 can be reduced, thereby reducing the thickness of the display device. In addition, when the vibrating device 530 and the first rear cover 310 and / or the second rear cover 350 are disposed adjacent to each other, abnormal vibrations may occur when the vibrating device 530 vibrates, so they may be spaced apart by a distance (D). For example, the vibrating device 530 may be spaced apart by a distance (D) from the first rear cover 310 and / or the second rear cover 350. For example, the distance (D) may be 1 mm or more, but is not limited thereto.

[0139] Referring to FIG. 3E , the vibration device 530 may be housed between the first rear cover 310 and the second rear cover 350. For example, the base plate 531 of the vibration device 530 may be casing. The base plate 531 of the vibration device 530 may be disposed between the first rear cover 310 and the second rear cover 350. An adhesive member 522 may be disposed between the first rear cover 310 and the vibration device 530. For example, the adhesive member 522 may be disposed on an extension portion 531 a of the base plate 531 and one side of the first rear cover 310. The adhesive member 522 may be one or more of, but is not limited to, double-sided tape, double-sided foam tape, double-sided padding, double-sided foam padding, and glue. By casing the base plate 531 of the vibration device 530, the thickness of the vibration device 530 can be reduced, thereby reducing the thickness of the display device. Furthermore, if the vibrating device 530 is disposed adjacent to the first rear cover 310 and the second rear cover 350, abnormal vibrations may occur when the vibrating device 530 vibrates, so the vibrating device 530 may be spaced apart by a distance (D). For example, the vibrating device 530 may be spaced apart by a distance (D) from the first rear cover 310 and the second rear cover 350. For example, the distance (D) may be 1 mm or more, but is not limited thereto.

[0140] FIG. 4 is a diagram showing the connecting member shown in FIGS. 3A to 3E.

[0141] 3A to 3E and 4, a connecting member 550 according to some examples herein may include first to fourth connecting portions 551, 552, 553, and 554. The first to fourth connecting portions 551, 552, 553, and 554 may be first to fourth coupling portions, and are not limited to the terms.

[0142] Each of the first to fourth connecting portions 551 , 552 , 553 , and 554 has a line shape with a certain width and length, and is disposed between the module structure 510 and the vibration transmitting member 570 .

[0143] According to some examples herein, based on the plan view of the modular structure 510 shown in FIG. 4 , the modular structure 510 may include a first front edge (or periphery) portion (or left side), a second front edge portion (or right side) parallel to the first front edge portion, a third front edge portion (or upper side) between one side (or part) of each of the first and second front edge portions, and a fourth front edge portion (or lower side) parallel to the third front edge portion and between the other side (or other part) of each of the first and second front edge portions.

[0144] The first connecting portion 551 may be positioned at a first front end portion of the modular structure 510, the second connecting portion 552 may be positioned at a second front end portion of the modular structure 510, the third connecting portion 553 may be positioned at a third front end portion of the modular structure 510, and the fourth connecting portion 554 may be positioned at a fourth front end portion of the modular structure 510.

[0145] Each of the first to fourth connecting portions 551, 552, 553, and 554 may have a structure separated from each corner of the modular structure 510. For example, each of the first to fourth connecting portions 551, 552, 553, and 554 may have an unseparated rectangular (e.g., square) band shape, which may result in wasting the remaining material excluding the connecting member 550 from the raw material for forming the connecting member 550, thereby increasing material costs.

[0146] By arranging a portion of each of the first to fourth connecting portions 551, 552, 553, 554 so that they are in contact with the connecting portions 551, 552, 553, 554 adjacent to each corner of the modular structure 510, it is possible to minimize the leakage of sound waves generated in the vibration space defined by the connecting member 550 to the outside.

[0147] At least one of the first to fourth connecting portions 551 , 552 , 553 , and 554 may include a bent portion 553 a or 554 a facing the vibration device 530 .

[0148] The sound waves generated by the vibration device 530 vibrating the display module 100 propagate radially from the center of the vibration device 530. These sound waves can be considered as progressive waves, but as these progressive waves propagate radially, they are reflected by the connecting member 550 to form reflected waves that propagate in the opposite direction to the progressive waves. These reflected waves overlap and interfere with the progressive waves, forming standing waves in which the overlapped sound waves cannot propagate and remain stationary. These standing waves can reduce sound pressure and degrade acoustic output characteristics. Therefore, the vents 553a and 554a are provided on the connecting member 550 to reduce the reduction in sound pressure caused by standing waves generated by interference between the reflected waves and the progressive waves. For example, the vents 553a and 554a may be formed at a point where the magnitude of the forward wave and the reflected wave is large or at least one of the connecting portions where the strongest sound waves arrive among the first to fourth connecting portions 551, 552, 553, and 554. For example, the vents 553a and 554a may be positioned toward the center of the vibrating device 530, for example, on an extension line (EL) of the center of the vibrating device 530, thereby minimizing the reduction in sound pressure caused by standing waves.

[0149] According to some examples herein, the vent portions 553a and 554a may be configured at the third and fourth connecting portions 553 and 554. The vent portions 553a and 554a may have a certain inclination angle (θ) with respect to the horizontal (or lateral) direction (X) of the display device. The inclination angle (θ) of the vent portions 553a and 554a according to some examples herein may vary depending on the required amount of standing wave suppression, and may be set to a value ranging from 10 degrees to 30 degrees, for example. For example, when the vibration device 530 outputs low-frequency sound or the output of the vibration device 530 is large, the vent portions 553a and 554a may have a relatively large inclination angle (θ). For example, when the vibration device 530 outputs high-frequency sound or the output of the vibration device 530 is small, the vent portions 553a and 554a may have a relatively small inclination angle (θ).

[0150] The third and fourth connecting portions 553 and 554 may have a symmetrical structure with respect to the vent portions 553a and 554a. The vent portions 553a and 554a may have an open structure on an extension line (EL) of the center of the vibration device 530, but are not limited thereto and may have a closed structure in the shape of a "V". When the vent portions 553a and 554a have an open structure on the extension line (EL) of the center of the vibration device 530, there is an advantage in that material costs can be reduced compared to when the vent portions have a closed structure. Furthermore, an acoustic property experiment confirmed that there is little or no difference in acoustic properties between when the vent portions 553a and 554a have an open structure on the extension line (EL) of the center of the vibration device 530 and when they have a closed structure.

[0151] The vent portions 553a and 554a can be applied to the first and second connecting portions 551 and 552 in the same or similar manner.

[0152] At least one of the first to fourth connecting portions 551, 552, 553, and 554 may include at least one protrusion 555, 556 facing the vibration device 530. For example, at least one protrusion 555, 556 may be configured on each of the first and second connecting portions 551, 552 so as to face the center of the vibration device 530. Such at least one protrusion 555, 556 can trap reflected waves, thereby reducing peaks and dips caused by standing waves and thereby minimizing the reduction in sound pressure.

[0153] 5A and 5B are diagrams illustrating a damper structure of a vibration device according to an embodiment of the present specification.

[0154] 5A is a diagram showing a vibration device with a single type structure, and FIG. 5B is a diagram showing a vibration device with a twin type structure. The twin type structure can also be expressed as a two-array structure. One vibration device according to this specification can be configured with a structure of two or more arrays, for example, a four-array structure or a six-array structure.

[0155] 3A to 3E and 5A, in a vibration device 530 according to an embodiment of the present specification, a damper 537 is coupled between an edge frame 536 disposed on a base plate 531 and a bobbin 534.

[0156] The damper 537 is configured to act as a wiring, and may include a first damper 537-1 that receives a positive polarity power supply (or a positive voice signal) and a second damper 537-2 that receives a negative polarity power supply (or a negative voice signal).

[0157] For example, the damper 537 may be divided into upper and lower parts based on the horizontal direction (X). For example, based on a center line in the horizontal direction (X) passing through the center of the bobbin 534, the first damper 537-1 may be disposed above the center line and the second damper 537-2 may be disposed below the center line. For example, the first damper 537-1 may be electrically connected to the first wiring terminal 530p, and the second damper 537-2 may be electrically connected to the second wiring terminal 530m. The wiring terminals 530p and 530m may be expressed as wiring pads or the like and are not limited to the terms. For example, the first wiring terminal 530p may be a + (plus) terminal, and the second wiring terminal 530m may be a - (minus) terminal.

[0158] According to some examples herein, each of the first damper 537-1 and the second damper 537-2 can include an inner portion 537a, an outer portion 537b, and a plurality of damping portions 537c.

[0159] The inner portion 537a may have a semicircular (or elliptical) shape and may be coupled or connected to the bobbin 534. For example, the center of the inner portion 537a having a semicircular (or elliptical) shape may be the same as the center of the bobbin 534. The inner portions 537a of the first damper 537-1 and the second damper 537-2 are electrically isolated from each other by being spaced apart (or separated) from each other on a center line in the lateral direction (X) that passes through the center of the bobbin 534.

[0160] The outer portion 537b has a semicircular (or elliptical) shape to surround the inner portion 537a, and can be disposed on or coupled to the edge frame 536. For example, the center of the outer portion 537b having a semicircular (or elliptical) shape can be the same as the center of the bobbin 534. The outer portions 537b of the first damper 537-1 and the second damper 537-2 are electrically isolated from each other by being spaced apart (or separated) from each other on a center line in the lateral direction (X) that passes through the center of the bobbin 534.

[0161] Each of the damping portions 537c is connected between the inner portion 537a and the outer portion 537b at a fixed distance or interval (or equal intervals). According to some examples herein, each of the damping portions 537c may have an S-shape or a zigzag shape. Each of the damping portions 537c adjusts the vibration of the bobbin 534 by contracting and relaxing in response to the up and down movement of the inner portion 537a due to the up and down vibration of the bobbin 534. Here, each of the damping portions 537c has a distance relatively longer than the shortest distance between the edge frame 536 and the bobbin 534. Therefore, the length of the damper 537 can be set long to reduce the thickness of the vibration device 530 and improve the performance of the magnet 532.

[0162] According to some examples herein, one end (or a portion) of each of the damping portions 537c is connected to the inner portion 537a. For example, the connecting portion between one end (or a portion) of each of the damping portions 537c and the inner portion 537a may be rounded into a curved shape, thereby preventing the damping portion 537c from breaking due to the up and down movement of the corresponding damping portion 537c.

[0163] 3A to 3E and 5B, a vibration device 530 according to another embodiment of the present specification can include two sub-vibration devices 530a and 530b arranged on a base plate 531. A vibration device 530 including such two sub-vibration devices 530a and 530b can be expressed as a twin-type vibration device, and is not limited to this term.

[0164] In the twin-type vibration device 530, the dampers 537 of the two sub-vibration devices 530a and 530b may be connected in parallel. The dampers 537 of the two sub-vibration devices 530a and 530b may be configured to function as wiring, and may include a first damper 537-1 that receives a positive polarity power supply (or a positive voice signal) and a second damper 537-2 that receives a negative polarity power supply (or a negative voice signal).

[0165] According to some examples in this specification, the damper 537 of each of the two sub-vibration devices 530a, 530b may be divided into upper and lower parts based on the lateral direction (X). For example, based on a center line in the lateral direction (X) passing through the center of the bobbin 534, the first damper 537-1 may be arranged above the center line and the second damper 537-2 may be arranged below the center line. For example, the first damper 537-1 may be electrically connected to the first wiring terminal 530p, and the second damper 537-2 may be electrically connected to the second wiring terminal 530m.

[0166] According to some examples herein, each of the first damper 537-1 and the second damper 537-2 may include an inner portion 537a, an outer portion 537b, and a plurality of damping portions 537c. Each of the first damper 537-1 and the second damper 537-2 is similar to the content described in FIG. 5A, and therefore, a repeated description thereof will be omitted.

[0167] The first dampers 537-1 of the two sub-vibration devices 530a and 530b are electrically connected to each other in the intermediate region of the base plate 531, and the second dampers 537-2 of the two sub-vibration devices 530a and 530b are also electrically connected to each other in the intermediate region of the base plate 531. This allows the dampers 537 of the two sub-vibration devices 530a and 530b to be connected in parallel.

[0168] In a vibration device 530 according to another embodiment of the present specification, the first wiring terminal 530p and the second wiring terminal 530m can be electrically connected to an audio amplifier (or an audio processing unit) via a signal cable (or a signal transmission member). As a result, the positions of the first wiring terminal 530p and the second wiring terminal 530m exposed on the base plate 531 can be changed to corners of the base plate 531 for easy electrical connection with the signal cable.

[0169] The vibration device 530 according to another embodiment may further include first to fourth brackets 539a, 539b, 539c, and 539d.

[0170] The first to fourth brackets 539a, 539b, 539c, and 539d can be disposed on or coupled to respective side surfaces of the base plate 531. For example, the first bracket 539a can be disposed on a first side surface (or a first short side) of the base plate 531, the second bracket 539b can be disposed on a second side surface (or a second short side) of the base plate 531, the third bracket 539c can be disposed on a third side surface (or a first long side) of the base plate 531, and the fourth bracket 539d can be disposed on a fourth side surface (or a second long side) of the base plate 531.

[0171] Each of the first to fourth brackets 539a, 539b, 539c, and 539d is fixed to the module structure 510 by the module integration member 520, thereby disposing or fixing the base plate 531 on the module structure 510.

[0172] As an example, each of the first to fourth brackets 539a, 539b, 539c, and 539d can be fixed or positioned to the module structure 510 via a module integration member 520 such as double-sided tape. For example, one surface of each of the first to fourth brackets 539a, 539b, 539c, and 539d facing the module structure 510 can have a flat surface structure to increase the adhesion area with the double-sided tape.

[0173] As another example, each of the first to fourth brackets 539a, 539b, 539c, and 539d may be disposed on or fixed to the module structure 510 via a module integration member 520 such as an adhesive (or bond). For example, one surface of each of the first to fourth brackets 539a, 539b, 539c, and 539d facing the module structure 510 may have an uneven structure having a plurality of rib patterns (RP) for restricting the flow of adhesive and preventing overflow.

[0174] As another example, each of the first to fourth brackets 539a, 539b, 539c, and 539d may be disposed on or fixed to the module structure 510 by a module integration member 520, such as a plurality of screws. For example, each of the first to fourth brackets 539a, 539b, 539c, and 539d facing the module structure 510 may include at least one hole (SH) through which at least one screw passes.

[0175] Each of the first to fourth brackets 539a, 539b, 539c, and 539d may basically include at least one hole (SH), and for compatibility during the modularization process between the vibration device 530 and the module structure 510 using the module integration member 520, one side of each of the first to fourth brackets 539a, 539b, 539c, and 539d may include a flat surface structure or a concave-convex structure.

[0176] FIG. 6 is a diagram showing a sound-generating module according to another embodiment of the present specification.

[0177] 6 shows a sound generating module according to the embodiment shown in FIGS. 3A to 3E, to which a heat dissipation structure has been added. Therefore, in the following description, the description of the remaining identical components, excluding the components related to the heat dissipation structure of the sound generating module, will be simplified or omitted.

[0178] Referring to FIGS. 2 and 6, a sound-generating module 500 according to another embodiment of the present disclosure includes a module structure 510 and a vibration device 530 .

[0179] The module structure 510 is a base structure of the sound-generating module 500, and is disposed on or fixed to the rear cover 300 via the first member 410. The module structure 510 includes a groove 510h that overlaps with the vibration device 530.

[0180] The groove 510h according to an embodiment of the present specification is formed to penetrate the modular structure 510 in the vertical direction (Z) and exposes the rear surface of the vibration device 530 to the rear cover 300. For example, the groove 510h may have a circular, elliptical, or polygonal shape, but is not limited thereto. The groove 510h may be expressed as a through hole or a hole, but is not limited to the terminology.

[0181] According to one embodiment of the present disclosure, the groove 510h may be smaller than the rear surface of the vibration device 530. For example, the groove 510h according to one embodiment of the present disclosure may be a heat release passage through which heat generated from the vibration device 530 travels toward the rear cover 300.

[0182] According to another embodiment of the present disclosure, the groove 510h may have a size that allows a portion of the rear surface of the vibrating device 530 to be accommodated or inserted therein. For example, the groove 510h may be a receiving hole that accommodates a portion of the rear surface of the vibrating device 530, and may also serve as a heat dissipation path through which heat generated from the vibrating device 530 travels toward the rear cover 300. Furthermore, the groove 510h according to another embodiment of the present disclosure may reduce the distance between the rear surface of the vibrating device 530 and the rear cover 300, thereby increasing heat dissipation efficiency.

[0183] As described above, the modular structure 510 further includes the platform 510h, and the remaining structure is the same as that of the modular structure shown in FIGS. 3A to 3E, and therefore, a redundant description thereof will be omitted.

[0184] The vibration device 530 may be disposed on or integrated with the module structure 510 via the module integration member 520 so as to overlap with the home 510h of the module structure 510. Such a vibration device 530 includes an actuator (or exciter) disposed so as to contact the rear surface of the display module 100. For example, the vibration device 530 made up of an actuator may include a base plate 531, a magnet 532, a center pole 533, a bobbin 534, a coil 535, an edge frame 536, a damper 537, and a hollow portion 530h.

[0185] The remaining configuration of vibration device 530, excluding base plate 531 and hollow portion 530h, is the same as that of the vibration device shown in FIGS. 3A to 3E, and therefore a duplicated description thereof will be omitted.

[0186] A rear surface of the base plate 531 according to an embodiment of the present disclosure may be positioned on a groove 510h of the modular structure 510. For example, when the groove 510h of the modular structure 510 is smaller than the size of the base plate 531, the rearmost surface of the base plate 531 may be seated on the modular structure 510 and positioned on the groove 510h.

[0187] According to another embodiment of the present specification, the rear surface of the base plate 531 may be inserted or housed in the groove 510h of the modular structure 510. For example, when the groove 510h of the modular structure 510 has a size equal to or larger than that of the base plate 531, a portion of the rear surface of the base plate 531 may be inserted or housed in the groove 510h of the modular structure 510. For example, the rearmost surface of the base plate 531 may be located inside the groove 510h of the modular structure 510 without passing through the groove 510h of the modular structure 510 and protruding outside the rearmost surface of the modular structure 510. This allows the thickness of the sound-generating module 500 to be reduced by the housing height (or depth) or insertion height (or depth) of the base plate 531 housed or inserted in the groove 510h of the modular structure 510, thereby slimming down the sound-generating module.

[0188] At least one of the extension 531a (or brackets 539a, 539b, 539c, and 539d) of the base plate 531 and the module integration member 520 is realized so that a portion of the rear surface of the base plate 531 is received in or inserted into the groove 510h of the modular structure 510. For example, the extension 531a (or brackets 539a, 539b, 539c, and 539d) of the base plate 531 may extend from an upper surface of the base plate 531 that is farthest from the rear surface of the base plate 531 so that a portion of the rear surface of the base plate 531 is received in or inserted into the groove 510h of the modular structure 510, or may have a relatively thin thickness. The thickness of the module integration member 520 may be set or varied within a range that allows a portion of the rear surface of the base plate 531 to be received in or inserted into the groove 510h of the modular structure 510.

[0189] The hollow portion 530h may penetrate the base plate 531, the magnet 532, and the center pole 533 in the vertical direction (Z) so as to overlap with the platform 510h of the modular structure 510. The hollow portion 530h may be a heat dissipation passage through which heat generated by the operation of the vibrating device 530 is dissipated toward the rear cover 300, and may increase the sound pressure generated by the operation of the vibrating device 530 and reduce the weight of the vibrating device 530. Furthermore, if the vibration space defined by the connecting member 550 is sealed, the sound pressure generated by the operation of the vibrating device 530 may be insufficient due to the limited sealed space. However, since the vibration space is connected to the outside through the hollow portion 530h, the sound pressure generated in the vibration space by the operation of the vibrating device 530 may increase.

[0190] According to some examples of the present specification, the vibration device 530 may further include a plurality of plate holes 531h formed in the base plate 531, overlapping the groove 510h of the modular structure 510. The plurality of plate holes 531h may penetrate the base plate 531 in the vertical direction (Z) to overlap at least one of the bobbin 534 and the magnet 532. For example, since the plate holes 531h overlapping the magnet 532 may be clogged during the manufacturing process of the vibration device 530, the plate holes 531h may be formed in the base plate 531 overlapping the bobbin 534. For example, each of the plurality of plate holes 531h may be formed radially on the back surface of the base plate 531, but is not limited to this example. The plate holes 531h may also be referred to as ventilation holes, but are not limited to this term. Such a plurality of plate holes 531h may further dissipate heat generated in the vibration device 530.

[0191] Therefore, the sound generating module 500 according to another embodiment of the present specification may have an improved heat dissipation function by including a groove 510h formed in the module structure 510 and a hollow portion 530h and a plate hole 531h formed in the vibration device 530, and the sound pressure generated in the vibration space by driving the vibration device 530 may be increased.

[0192] FIG. 7 is a diagram showing a rear cover that covers the rear surface of the sound generating module according to another embodiment of the present specification shown in FIG.

[0193] 7 shows a case where a plurality of holes (or vent holes) are further configured on the rear cover overlapping the sound generating module. Therefore, in the following description, the redundant description of the remaining same components except for the components related to the plurality of holes will be simplified or omitted.

[0194] Referring to FIGS. 2, 6 and 7, a rear cover 300 according to another embodiment of the present disclosure may include a plurality of holes 300 h overlapping with the sound generating module 500 .

[0195] Each of the holes 300h may be formed to vertically penetrate both the second rear cover 350 and the first rear cover 310 of the rear cover 300 in the thickness direction (Z) and overlap with the vibration device 530.

[0196] The plurality of holes 300h may be arranged radially to overlap with the hollow portion 530h formed in the vibration device 530. According to some examples herein, the plurality of holes 300h may be arranged radially at a certain distance or interval (or at equal intervals) based on the center of the hollow portion 530h formed in the vibration device 530. For example, the plurality of holes 300h may be spaced apart at regular intervals on the circumference of each of a plurality of concentric circles that are concentric with the hollow portion 530h formed in the vibration device 530.

[0197] According to some examples of the present specification, each of the plurality of holes 300h may have a certain width and a certain length set within a range that does not detract from the clean-back design of the display device. If each of the plurality of holes 300h has a line or hole shape that is large enough to be easily distinguishable from the rear cover 300, the clean-back design of the display device will not be realized. Therefore, each of the plurality of holes 300h has a size that allows air outside the display device to enter and exit the interior of the sound-generating module 500 or the hollow portion 530h formed in the vibration device 530, so as not to detract from the clean-back design of the display device.

[0198] FIG. 8 is another schematic cross-sectional view taken along line II' in FIG. 1, illustrating a display device according to another embodiment of the present specification.

[0199] 1 and 8, a display device according to another embodiment of the present specification includes one sound-generating module 500 between the display module 100 and the rear cover 300. In the example shown in FIG.

[0200] The display module 100 and the rear cover 300 are similar to the display module and the rear cover shown in FIG. 2 and FIGS. 3A to 3E, respectively, and therefore will not be described again.

[0201] One sound generating module 500 can be configured by modularizing the first and second sound generating modules 500-1 and 500-2 shown in FIG. 2 and FIGS. 3A to 3E into a single component.

[0202] According to some examples herein, one sound-generating module 500 includes a modular structure 1510, a first vibrating device 530-1, and a second vibrating device 530-2.

[0203] The module structure 1510 is disposed on or fixed to the rear cover 300 via the first member 410 (or the first module fixing member). The rear surface of the module structure 1510 is completely covered by the rear cover 300 and is therefore concealed and not directly exposed to the outermost rear surface of the display device. This module structure 1510 is similar to the module structures shown in FIGS. 2 and 3A to 3E except that the module structures 510 of the first and second sound-generating modules 500-1 and 500-2 shown in FIGS. 2 and 3A to 3E are each formed into a single plate-like structure, and therefore a repeated description thereof will be omitted.

[0204] The first vibrating device 530-1 is disposed on or fixed to a first region of the module structure 1510 to vibrate the first region (or the left region) of the display module 100, for example, the display panel 110. For example, the first vibrating device 530-1 can be disposed on, fixed to, or integrated into the first region of the module structure 1510 via the module integration member 520. According to some examples herein, the first vibrating device 530-1 can be disposed in the exact center of the first region of the module structure 1510, or can be disposed so as to be biased toward an edge (or peripheral) portion of the first region of the module structure 1510.

[0205] The second vibrating device 530-2 is disposed on or fixed to the second region of the module structure 1510 to vibrate the second region (or right region) of the display module 100, for example, the display panel 110. For example, the second vibrating device 530-2 can be disposed on, fixed to, or integrated into the second region of the module structure 1510 via the module integration member 520. According to some examples herein, the second vibrating device 530-2 can be disposed in the exact center of the second region of the module structure 1510, or can be disposed biased toward the edge (or peripheral) portion of the second region of the module structure 1510. For example, the second vibrating device 530-2 can be disposed symmetrically to the first vibrating device 530-1 with respect to the center of the module structure 1510.

[0206] 2 and 3A to 3E except that the first and second vibration devices 530-1 and 530-2 are arranged together on a single module structure 1510, and therefore a redundant description thereof will be omitted. Each of the first and second vibration devices 530-1 and 530-2 may have a single-type structure as shown in FIG. 5A or a twin-type structure as shown in FIG. 5B.

[0207] Although the example of one sound generating module 500 shown in FIG. 8 includes two vibration devices 530-1 and 530-2, this is not necessarily limited to this and may include three or more vibration devices. In this case, the display device can output three or more channels of stereo sound (PVS) through the vibration of each of the three or more vibration devices built into one sound generating module 500.

[0208] One sound-generating module 500 may further include a connecting member 550 and a partition member 560 .

[0209] The connecting member 550 may be interposed between the modular structure 1510 and the display module 100. For example, the connecting member 550 may be interposed between an edge (or peripheral) portion of the modular structure 1510 and the display module 100. For example, the connecting member 550 may be configured to entirely surround a plurality of vibration devices 530-1, 530-2 disposed on or fixed to the modular structure 1510.

[0210] The partition member 560 is disposed between the plurality of vibration devices 530-1 and 530-2 fixed on the modular structure 1510, and spatially separates the first and second regions of the modular structure 1510. For example, the partition member 560 may include first and second partitions 561 and 562 disposed side by side in a central region between the first and second regions of the modular structure 1510. The first and second partitions 561 and 562 can reduce the influence of vibrations generated in the first and second regions of the modular structure 1510 on acoustic characteristics resulting from differences in mid- and high-range resonance frequencies between the first and second regions of the display module 100, for example, the display panel 110.

[0211] One sound-generating module 500 may further include a vibration transmission member 1570 and a second member 430 .

[0212] The vibration transmission member 1570 is disposed on or coupled to the connecting member 550, the partition member 560, and each of the plurality of vibrating devices 530-1 and 530-2, vibrates in response to the vibration of each of the plurality of vibrating devices 530-1 and 530-2, and transmits the vibration of each of the plurality of vibrating devices 530-1 and 530-2 to the display module 100, for example, the display panel 110. The vibration transmission member 1570 is the same as the vibrating device shown in FIGS. 2 and 3A to 3E except that it is additionally coupled to the partition member 560 and each of the plurality of vibrating devices 530-1 and 530-2, and therefore a repeated description thereof will be omitted.

[0213] The second member 430 may be a double-sided adhesive member interposed between the display module 100 and the vibration transmission member 570. The double-sided adhesive member may be, but is not limited to, a double-sided tape or a double-sided foam tape. The second member 430 is similar to the second member 430 shown in Fig. 2 and Figs. 3A to 3E, and therefore a repeated description thereof will be omitted.

[0214] Therefore, the display device according to another embodiment of the present specification includes a single module structure 1510 and a single sound-generating module 500 in which multiple vibration devices 530-1, 530-2 are modularized into a single component, thereby further improving the assembly of the sound-generating module 500 during the assembly process between modules, thereby further improving the production yield of the display device.

[0215] FIG. 9 is a view showing the connecting member and the partition member shown in FIG.

[0216] 8 and 9, a connecting member 550 according to an embodiment of the present specification may include first to fourth connecting portions 1551, 1552, 1553, and 1554. FIG.

[0217] Each of the first to fourth connecting parts 1551, 1552, 1553, and 1554 may be interposed between the front edge (or peripheral) portion of the module structure 1510 and the display module 100, or may be disposed between the front edge (or peripheral) portion of the module structure 1510 and the vibration transmission member 1570.

[0218] According to some examples in the present specification, each of the first to fourth connecting portions 1551, 1552, 1553, and 1554 may have a line shape with a certain width and length.

[0219] According to some examples herein, based on the plan view of the modular structure 1510 shown in FIG. 9 , the modular structure 1510 may include a first front edge (or peripheral) portion (or left edge), a second front edge (or peripheral) portion (or right edge) parallel to the first front edge (or peripheral) portion, a third front edge (or peripheral) portion (or upper edge) between one side (or part) of each of the first and second front edge (or peripheral) portions, and a fourth front edge (or peripheral) portion (or lower edge) between the other side (or other part) of each of the first and second front edge (or peripheral) portions parallel to the third front edge (or peripheral) portion.

[0220] The first connection portion 1551 may be positioned at a first front end portion of the modular structure 1510, the second connection portion 1552 may be positioned at a second front end portion of the modular structure 1510, the third connection portion 1553 may be positioned at a third front end portion of the modular structure 1510, and the fourth connection portion 1554 may be positioned at a fourth front end portion of the modular structure 1510.

[0221] Each of the first to fourth connecting portions 1551, 1552, 1553, and 1554 may have a structure separated from each corner of the modular structure 510. For example, each of the first to fourth connecting portions 1551, 1552, 1553, and 1554 may have a rectangular (e.g., square) strip shape that is not separated, which may result in increased material costs due to the waste of material remaining after excluding the connecting member 550 from the raw materials used to form the connecting member 550.

[0222] By arranging a portion of each of the first to fourth connecting portions 1551, 1552, 1553, and 1554 so that they are in contact with the adjacent first to fourth connecting portions 1551, 1552, 1553, and 1554 at each corner of the modular structure 1510, it is possible to reduce or minimize the leakage of sound waves generated in the vibration space defined by the connecting member 550 to the outside.

[0223] At least one of the first to fourth connecting portions 1551, 1552, 1553, and 1554 may include a plurality of vent portions 1553a and 1554a directed toward the corresponding first and second vibrating devices 530-1 and 530-2.

[0224] Each of the plurality of vents 1553a, 1554a may be formed at at least one connecting portion where the magnitude of the forward wave and the reflected wave is large or where the strongest sound wave arrives among the first to fourth connecting portions 1551, 1552, 1553, and 1554. For example, each of the plurality of vents 1553a, 1554a may be positioned on an extension line (EL) of the center of the corresponding first and second vibrating devices 530-1, 530-2 so as to face the center of the corresponding first and second vibrating devices 530-1, 530-2, thereby minimizing the reduction in sound pressure caused by standing waves.

[0225] According to some examples of the present specification, each of the plurality of vent portions 1553a, 1554a may be configured in at least one of the third and fourth connection portions 1553, 1554. Each of the plurality of vent portions 1553a, 1554a may have a certain inclination angle (θ) with respect to the horizontal (or lateral) direction (X) of the display device. The inclination angle (θ) of each of the plurality of vent portions 1553a, 1554a according to some examples of the present specification may vary depending on the required amount of standing wave suppression, and may be set to a variable value between 10 degrees and 30 degrees, for example.

[0226] Each of the plurality of vent portions 1553a, 1554a may have an open structure on an extension line (EL) of the center of the corresponding first and second vibration devices 530-1, 530-2, but is not necessarily limited to this and may have a closed structure in the shape of a "V".

[0227] Also, each of the plurality of vent portions 1553a, 1554a can be applied to at least one of the first and second connecting portions 1551, 1552 in the same or similar manner.

[0228] At least one of the first to fourth connecting portions 1551, 1552, 1553, and 1554 may include at least one first protrusion 555, 556 facing the corresponding first and second vibrating devices 530-1 and 530-2. For example, at least one first protrusion 555, 556 may be configured on each of the first and second connecting portions 1551 and 1552 so as to face the center of the corresponding first and second vibrating devices 530-1 and 530-2. Such at least one first protrusion 555, 556 can trap reflected waves and reduce peaks and dips caused by standing waves, thereby minimizing the reduction in sound pressure.

[0229] The partition member 560 may include first and second partitions 561 , 562 positioned alongside each other in a central region between the first and second regions of the modular structure 1510 .

[0230] The first and second partitions 561, 562 are arranged between the third and fourth connecting portions 1553, 1554 so as to be parallel to the first and second connecting portions 1551, 1552, respectively. For example, the first and second partitions 561, 562 may have the same width as the first to fourth connecting portions 1551, 1552, 1553, 1554, respectively, but are not limited to this.

[0231] One side (or a portion) of each of the first and second partitions 561 and 562 may contact or be close to the third connecting portion 1553 in a non-contact state. The other side (other portion) of each of the first and second partitions 561 and 562 may contact or be close to the fourth connecting portion 1554 in a non-contact state. The first and second partitions 561 and 562 may reduce the influence of vibrations generated in the first and second regions of the module structure 1510 on acoustic characteristics resulting from differences in mid- and high-range resonance frequencies between the first and second regions of the display module 100, for example, the display panel 110.

[0232] Each of the first and second partitions 561, 562 according to some examples herein may include at least one second protrusion 563, 564.

[0233] According to some examples herein, the at least one second protrusion 563 included in the first partition 561 can be configured on the first partition 561 to face the center of the first vibration device 530-1. The at least one second protrusion 564 included in the second partition 562 can be configured on the second partition 562 to face the center of the second vibration device 530-2. Each of the at least one second protrusion 563, 564 can trap reflected waves and reduce peaks and dips caused by standing waves, thereby minimizing the reduction in sound pressure.

[0234] Fig. 10 is another cross-sectional view taken along line II' shown in Fig. 1. Fig. 11 is a view showing the rear cover shown in Fig. 10.

[0235] 10 shows a rear cover according to an embodiment of the present specification, in which a module receiving section is added. Therefore, in the following description, redundant descriptions of the remaining same components except for the module receiving section and its related components will be omitted or simplified.

[0236] 10 and 11, the rear cover 300 according to the embodiment of the present specification further includes at least one module receiving portion 370 for receiving at least one sound generating module 500 therein.

[0237] At least one module accommodating portion 370 is formed in the first rear cover 310 of the rear cover 300 and is covered by the second rear cover 350. For example, the at least one module accommodating portion 370 is formed to penetrate the first rear cover 310 of the rear cover 300 vertically in the thickness direction (Z) and is covered by the second rear cover 350. The at least one module accommodating portion 370 is formed only in the first rear cover 310 and not in the second rear cover 350 to slim the thickness of the display device and achieve a clean back design of the display device, and is therefore not exposed to the outside of the rear cover 300. Since the at least one module accommodating portion 370 does not completely penetrate the rear cover 300, it can also be referred to as a module accommodating groove. The at least one module accommodating portion 370 can also be referred to as a module insertion portion, module insertion groove, module accommodating portion, module accommodating groove, or groove, but these terms are not limited to these.

[0238] According to some examples herein, the rear cover 300 may include two module receiving portions 370 in which the first sound-generating module 500-1 and the second sound-generating module 500-2 are respectively received and disposed.

[0239] According to some examples herein, each of the two module receiving portions 370 has a size capable of receiving a corresponding sound-generating module 500. Each of the two module receiving portions 370 may have a height (or depth) that is smaller than the overall height of the sound-generating module 500. Since each of the two module receiving portions 370 is formed by penetrating the first rear cover 310, the thickness of the first rear cover 310 may have a height (or depth) that is smaller than the overall height of the sound-generating module 500. If the thickness of the first rear cover 310 is greater than the overall height of the sound-generating module 500, the gap space (GS) disposed between the display module 100 and the rear cover 300 may not have sufficient height, and physical contact between the display module 100 and the first rear cover 310, which vibrate due to the driving of the vibration device 530, may not generate desired sound or may generate noise such as a frictional sound. Therefore, the thickness of the first rear cover 310 or the height (or depth) of the module accommodating portion 370 can be set within a range that can prevent physical contact between the display module 100, which vibrates when the vibration device 530 is driven, and the first rear cover 310.

[0240] According to some examples in this specification, at least one sound-generating module 500 is disposed on the second rear cover 350 exposed by the module accommodating portion 370 via the first member 410 (or module fixing member), and is similar to the sound-generating modules shown in Figures 2 to 5B except that it is disposed on the rear of the display module 100, and therefore a redundant description thereof will be omitted.

[0241] According to another embodiment of the present specification, the rear cover 300 may include one module receiving portion 370 in which the single sound generating module 500 shown in Figures 8 and 9 is received. In this case, the module receiving portion 370 is also formed to penetrate the first rear cover 310 of the rear cover 300 vertically in the thickness direction (Z) and is covered by the second rear cover 350.

[0242] Therefore, in the display device according to another embodiment of the present specification, at least one sound-generating module 500 is accommodated in the module accommodating portion 370 formed in the rear cover 300, so that the thickness may be reduced by the height (or depth) of the module accommodating portion 370 and the weight may be reduced by the size of the module accommodating portion 370. In the display device according to another embodiment of the present specification, the sound-generating module 500 is accommodated in the module accommodating portion 370 disposed in the rear cover 300, so that the assembly process between the sound-generating module 500 and the rear cover 300 may be simplified.

[0243] As another example, the rear cover 300 includes a plurality of holes 300 h overlapping with at least one module receiving portion 370 .

[0244] Each of the plurality of holes 300h is formed to vertically penetrate the second rear cover 350 of the rear cover 300 in the thickness direction (Z) and communicate (or connect) with at least one module receiving portion 370. The plurality of holes 300h may be radially arranged to overlap with the sound generating module 500 received in at least one module receiving portion 370. The shape and size of each of the plurality of holes 300h are similar to the description of FIG. 7 due to the clean back design of the display device, and therefore, a repeated description thereof will be omitted.

[0245] 12 is a diagram showing a display device according to another embodiment of the present specification, and FIG 13 is a cross-sectional view taken along line II-II' shown in FIG 12.

[0246] 12 and 13 show the display device shown in Fig. 10 and 11, with the sound generating module structure changed. Therefore, in the following description, redundant description of the remaining components excluding the sound generating module will be omitted or simplified.

[0247] Referring to Figures 12 and 13, a display device according to another embodiment of the present specification includes at least one sound-generating module 500 disposed between the display module 100 and the rear cover 300 and vibrating the display module 100, and the at least one sound-generating module 500 is accommodated in at least one module accommodating portion 370 provided in the rear cover 300.

[0248] At least one module receiving portion 370 provided in the rear cover 300 is the same as the module receiving portion shown in FIGS. 10 and 11, and therefore a duplicated description thereof will be omitted.

[0249] The at least one sound-generating module 500 is modularized as a single component and accommodated in at least one module accommodating portion 370 provided in the rear cover 300. According to some examples herein, the at least one sound-generating module 500 is accommodated in at least one module accommodating portion 370 provided in the first rear cover 310 of the rear cover 300 and supported on the front surface of the first rear cover 310. For example, the at least one sound-generating module 500 may have a box structure with an opening on one side and a frame. The at least one sound-generating module 500 directly vibrates the display module 100, thereby generating sound (PVS) due to vibration of the display module 100, for example, the display panel 110.

[0250] According to one embodiment of the present specification, the center portion of the rear surface of the sound-generating module 500 passes through the module receiving portion 370 and is disposed or fixed to the second rear cover 350 via the first member 410 (or module fixing member). The frame portion (or boundary portion) of the sound-generating module 500 is supported (or mounted) on the front surface of the first rear cover 310 and disposed or connected to the rear surface of the display module 100, for example, the display panel 110, via the connecting member 550, or disposed or connected to the rear surface of the heat diffusion member 150 disposed at the rearmost part of the display module 100 via the connecting member 550.

[0251] According to another embodiment of the present disclosure, the sound-generating module 500 may be disposed or fixed to the second rear cover 350 by a plurality of screws. For example, a frame portion (or a boundary portion) of the sound-generating module 500 may be disposed or fastened to the first rear cover 310 by a plurality of screws. For example, each of the plurality of screws may pass through the connecting member 550 and the frame portion of the sound-generating module 500 and be disposed or fastened to the first rear cover 310.

[0252] According to another embodiment of the present disclosure, the sound-generating module 500 may be disposed or fixed to the second rear cover 350 using a bolt and a nut. The nut may be disposed or fixed to the front surface of the first rear cover 310 that overlaps the frame portion of the sound-generating module 500. The bolt may pass through the connecting member 550 and the frame portion of the sound-generating module 500 and be fastened to the nut. The nut according to one embodiment of the present disclosure may be a self-clinching nut fixed to the front surface of the first rear cover 310.

[0253] Therefore, in the display device according to another embodiment of the present specification, by accommodating and disposing at least one sound-generating module 500 in the module accommodating portion 370 formed in the rear cover 300, the thickness can be reduced by the height (or depth) of the module accommodating portion 370 and the weight can be reduced by the size of the module accommodating portion 370. In the display device according to another embodiment of the present specification, by accommodating and disposing the sound-generating module 500 in the module accommodating portion 370 formed in the rear cover 300, the assembly process between the sound-generating module 500 and the rear cover 300 can be simplified.

[0254] Fig. 14 is a diagram showing the sound generating module shown in Fig. 12 and Fig. 13. Fig. 15 is a diagram showing the module structure shown in Fig. 14.

[0255] 12 to 15, a sound generating module 500 according to another embodiment of the present specification includes a module structure 2510, a vibration device 530, a connecting member 550, and a module adhesive member 450.

[0256] The module structure 2510 is accommodated in the module accommodating portion 370 formed in the rear cover 300 to accommodate or fix (or support) the vibration device 530. According to some examples herein, the module structure 2510 may be made of a formable metal material.

[0257] The modular structure 2510 according to some examples herein can include a frame (or border) 511, a bottom 513, and a sloped portion 515. The frame 511 can be expressed as a first portion, the bottom 513 as a second portion, and the sloped portion 515 as a third portion, without being limited by these terms.

[0258] The frame 511 has a rectangular (e.g., square) band shape and is supported (or mounted) on the front surface of the rear cover 300, e.g., the first rear cover 310, which is in contact with the module receiving portion 370. For example, the frame 511 may be a frame portion (or an edge or boundary portion) of a metal plate, which is a base material for forming the module structure 2510.

[0259] The bottom portion 513 is disposed on or fixed to the second rear cover 350 of the rear cover 300 exposed by the module accommodating portion 370. For example, the bottom portion 513 can pass through the module accommodating portion 370 and be disposed on or fixed to the second rear cover 350 via the first member 410 (or a module fixing member).

[0260] The inclined portion 515 is formed to be inclined between the frame portion 511 and the bottom portion 513, thereby defining a storage space on the bottom portion 513. For example, the bottom portion 513 and the inclined portion 515 may have a structure in which the remaining portion of the metal plate excluding the frame portion protrudes toward the rear cover 300 through a molding process using a mold. The bottom portion 513 and the inclined portion 515 may be expressed as a storage portion, a forming portion, a pocket portion, or the like for storing the vibration device 530, and are not limited to the terms.

[0261] According to some examples herein, the height (H) of the inclined portion 515 or the height (H) between the rear surface of the bottom portion 513 and the rear surface of the frame portion 511 may be the same as or lower than the height of the first rear cover 310. If the height (H) of the inclined portion 515 is higher than the height of the first rear cover 310, the frame portion 511 may not be stably supported on the front surface of the first rear cover 310, and a portion of the inclined portion 515 and the frame portion 511 may protrude above the front surface of the first rear cover 310, which may cause a problem that the portion of the inclined portion 515 and the frame portion 511 vibrate due to vibration of the display module 100. Therefore, the height (H) of the inclined portion 515 or the height (H) between the rear surface of the bottom portion 513 and the rear surface of the frame portion 511 should be set to be the same as or lower than the height of the first rear cover 310 so that the frame portion 511 is stably supported (or seated) on the front surface of the first rear cover 310.

[0262] The vibration device 530 is housed in a storage space of the module structure 2510. The vibration device 530 according to some examples herein may be disposed on or fixed to the bottom 513 of the module structure 2510 to vibrate the display module 100, for example, the display panel 110. The vibration device 530 is disposed on, fixed to, or integrated with the module structure 2510 via a module integration member 520, whereby the vibration device 530 and the module structure 2510 are modularized as a single component.

[0263] The vibration device 530 according to some examples herein may include any acoustic device or vibration generating device that can vibrate the display module 100 in response to an electrical signal. According to some examples herein, the vibration device 530 includes an actuator (or exciter) arranged to contact the rear surface of the display module 100. For example, the vibration device 530 including the actuator includes a base plate 531, a magnet 532, a center pole 533, a bobbin 534, a coil 535, an edge frame 536, and a damper 537, which are similar to the description related to the vibration device shown in FIGS. 2 to 5B, and therefore, a repeated description thereof will be omitted.

[0264] The top surface of the vibration device 530 according to some examples of the present specification may be located on the same horizontal line (HL) as the frame 511 of the modular structure 2510, or may protrude above the top extension line of the frame 511. For example, if the top surface of the vibration device 530 is located below the top extension line (HL) of the frame 511 and is completely housed in the housing space of the modular structure 2510, it may be difficult to combine or connect the vibration device 530 with the rear surface of the display module 100. Therefore, in order to combine or connect the vibration device 530 with the rear surface of the display module 100 through only a simple module placement process, the top surface of the vibration device 530 may protrude above the top extension line (HL) of the frame 511.

[0265] The connecting member 550 is interposed between the frame portion 511 of the module structure 2510 and the rear surface of the display module 100, thereby creating a gap space (GS) between the rear surface of the display module 100 and the rear cover 300, and positioning or connecting the module structure 2510 to the rear surface of the display module 100.

[0266] According to some examples herein, one surface (or front surface) of the connecting member 550 is disposed on or coupled to the display module 100, for example, the display panel 110 or the rear surface of the heat diffusion member 150 coupled to the rear surface of the display panel 110, and the other surface (or rear surface) of the connecting member 550 is disposed on or coupled to the frame 511 of the module structure 2510. For example, the connecting member 550 may be, but is not limited to, double-sided tape or double-sided foam tape. The connecting member 550 provides a vibration space surrounding the vibration device 530 between the module structure 2510 and the display module 100.

[0267] The module adhesive member 450 may be a double-sided adhesive member interposed between the display module 100 and the vibration device 530. The double-sided adhesive member may be, but is not limited to, double-sided tape or double-sided foam tape. One surface (or front surface) of the module adhesive member 450 is disposed on or coupled to the display module 100, for example, the display panel 110 or the rear surface of the heat diffusion member 150 disposed on the rear surface of the display panel 110, and the other surface (or rear surface) of the module adhesive member 450 is disposed on or coupled to the bobbin 534 or bobbin protection member 538 of the vibration device 530.

[0268] As another example, the heat diffusion member 150 coupled to or disposed on the rear surface of the display panel 110 may be integrated into the sound-generating module 500. For example, the heat diffusion member 150 is coupled to or disposed on each of the connecting member 550 and the module adhesive member 450 of the sound-generating module 500 to cover the front surface of the sound-generating module 500. This prevents the vibration device 530, the connecting member 550, and the module adhesive member 450 of the sound-generating module 500 from being exposed to the outside during transportation of the sound-generating module 500 modularized into a single component after a modularization process, and prevents foreign matter such as dust from penetrating into the sound-generating module 500.

[0269] A sound-generating module 500 according to another embodiment of the present specification may further include at least one of a groove provided on the bottom 513 of the modular structure 2510 to overlap the vibration device 530, a hollow portion passing through each of the base plate 531, magnet 532, and center pole 533 of the vibration device 530 in the vertical direction (Z) to overlap the groove, and a plurality of plate holes formed in the base plate 531 to overlap each of the magnet 532 and bobbin 534 of the vibration device 530. For example, the groove, hollow portion, and plurality of plate holes substantially correspond to the groove 510h, hollow portion 530h, and plurality of plate holes 531h of the sound-generating module 500 shown in FIG. 6, and therefore, a repeated description thereof will be omitted. For example, the groove 510h, hollow portion 530h, and plurality of plate holes 531h of the sound-generating module 500 shown in FIG. 6 may be the same as or similar to the corresponding configurations of the sound-generating module shown in FIG. 14.

[0270] 16A and 16B are diagrams illustrating a rear view and a vibration device and a voice signal cable disposed on a modular structure of a sound-generating module according to an embodiment of the present disclosure, respectively.

[0271] Referring to FIGS. 16A and 16B, a modular structure 2510 according to an embodiment of the present disclosure includes a home 510h and a plurality of cable holes 517 (or cable passage holes).

[0272] The groove 510h is formed by penetrating the bottom 513 of the modular structure 2510 in the vertical direction (Z) so as to overlap the vibration device 530. The groove 510h can accommodate a portion of the rear surface of the vibration device 530. For example, the groove 510h can have a quadrilateral (e.g., rectangular) shape corresponding to the base plate 531 of the vibration device 530, but is not limited thereto. For example, the groove 510h can have a circular or elliptical shape.

[0273] According to some examples herein, the home 510h exposes wiring terminals 530p, 530m of the vibration device 530 on the back surface of the modular structure 2510.

[0274] Each of the plurality of cable holes 517 extends from a corner of the platform 510h to have a certain size and shape and communicates with each corner of the platform 510h. For example, each of the plurality of cable holes 517 may be a passage through which a voice signal cable 590 electrically connected to the wiring terminals 530p, 530m of the vibration device 530 exposed in the platform 510h is pulled out toward the storage space of the modular structure 2510. Thus, the voice signal cable 590 is electrically connected to the wiring terminals 530p, 530m of the vibration device 530 exposed in the platform 510h, and then pulled out into the storage space of the modular structure 2510 through a corresponding one of the plurality of cable holes 517. The voice signal cable 590 pulled out into the storage space of the modular structure 2510 is then pulled out to the outside of the modular structure 2510 via the bottom 513, inclined portion 515, and frame portion 511 of the modular structure 2510.

[0275] The module structure 2510 according to the embodiment of the present specification stores the voice signal cable 590 connected to the wiring terminals 530p, 530m of the vibration device 530, thereby preventing defects such as breakage of the voice signal cable 590 during transportation after the modularization process of the sound generating module 500 modularized as a single component.

[0276] FIG. 17 is a diagram showing the rear surface of a rear cover according to an embodiment of the present specification.

[0277] FIG. 17 is a diagram for explaining the layout structure of a voice signal cable that applies a voice signal to the sound generating module.

[0278] Referring to Figures 12 and 17, the voice signal cable 590 according to the embodiments of the present specification is arranged between the display module 100 and the sound generating module 500, and can be pulled out to the outside through the cable outlet 390 provided in the rear cover 300.

[0279] According to some examples herein, one end (or a portion) of the voice signal cable 590 is electrically connected to a wiring terminal provided on the corresponding sound-generating module 500. For example, one end (or a portion) of the voice signal cable 590 can be electrically connected to the wiring terminal provided on the corresponding sound-generating module 500 by soldering.

[0280] According to some examples herein, the other end (or another portion) of the voice signal cable 590 may pass through the storage space of the corresponding sound-generating module 500 and between the display module 100 and the sound-generating module 500, be pulled out to the outside of the storage space of the corresponding sound-generating module 500, and then pass between the display module 100 and the rear cover 300, and be pulled out to the outside of the display device through the cable outlet 390. In FIG. 17 , a portion of the voice signal cable 590 represented by a dotted line is hidden by the rear cover 300 and is therefore not visible from the rear of the rear cover 300, while the remaining portion of the voice signal cable 590 represented by a thick solid line is pulled out to the outside of the display device through the cable outlet 390 and is therefore visible from the rear of the rear cover 300. The voice signal cable 590 pulled out through the cable outlet 390 is then covered by a circuit cover or cover shield that covers the circuits of the display device.

[0281] Therefore, the display device according to the embodiment of the present specification can have a clean back design by covering the voice signal cable 590 and the sound generating module 500 with the rear cover 300 .

[0282] Fig. 18 is a diagram showing a display device according to another embodiment of the present specification. Fig. 19 is a cross-sectional view taken along line III-III' in Fig. 18. Fig. 20 is another cross-sectional view taken along line III-III' in Fig. 18. Fig. 21 is another cross-sectional view taken along line III-III' in Fig. 18.

[0283] 18 and 19 show modifications to the structure of the rear cover according to the examples of the present specification based on the display device shown in Figures 12 to 17. Therefore, in the following, redundant descriptions of the configuration other than the rear cover and its related configuration will be omitted or will be explained briefly.

[0284] First, in the display devices shown in FIGS. 12 to 17 , the rear cover 300 includes multiple module receiving sections 370 for receiving or inserting the sound-generating modules 500 modularized as a single component. Depending on the structure of the final display device, if a display device is equipped with only a single sound-generating module 500, a rear cover 300 including only one module receiving section 370 is used. Also, depending on the structure of the final display device, if a display device is equipped with no sound-generating module 500, a rear cover 300 without a module receiving section 370 is used. This results in significant costs associated with manufacturing rear covers that correspond to the respective structures of the final display device, thereby increasing the manufacturing cost of the display device. To address these issues, the display devices according to the embodiments of the present specification include a rear cover that can be used in common regardless of the structure of the final product. For example, by including a rear cover that can be used in common regardless of the structure of the final product, the cost of manufacturing a rear cover for a display device that does not include a sound-generating module 500 and a display device that includes a sound-generating module 500 can be reduced, such as mold costs, and the modularization of the sound-generating module can improve the flexibility of the placement of the sound-generating module in the final product.

[0285] 18 and 19, a display device according to another embodiment of the present specification includes first to third sound generating modules 500-1, 500-2, and 500-3 arranged between the display module 100 and the rear cover 1300. In the example shown in FIG.

[0286] The display module 100 is similar to the display module shown in FIG. 2 and FIGS. 3A to 3E, and therefore a duplicated description thereof will be omitted.

[0287] The rear cover 1300 is a shared rear cover and includes a plurality of module accommodating portions 370a, 370b, and 370c. Each of the plurality of module accommodating portions 370 is formed in the rear cover 1300 by penetrating the first rear cover 310 in the vertical direction (Z). For example, the rear cover 1300 may include a first module accommodating portion 370a overlapping a first region (or left region) of the display module 100, a second module accommodating portion 370b overlapping a second region (or right region) of the display module 100, and a third module accommodating portion 370c overlapping a third region (or central region) between the first and second regions of the display module 100.

[0288] The first to third sound-generating modules 500-1, 500-2, 500-3 are respectively housed and arranged in the plurality of module housing portions 370a, 370b, 370c, and individually vibrate the first to third regions of the display module 100, for example, the display panel 110. The first to third sound-generating modules 500-1, 500-2, 500-3 are the same as the sound-generating modules shown in Figures 3A to 3E, 6, 10, and 14 to 16B, and therefore a repeated description thereof will be omitted.

[0289] Therefore, the display device according to another embodiment of this specification can output three-channel stereo sound consisting of left sound (LS), right sound (RS), and center sound (CS) by vibrating the display module 100, for example, the display panel 110, by driving each of the first to third sound generating modules 500-1, 500-2, 500-3.

[0290] As another example, a display device according to another embodiment of the present specification may be configured to include a portion of the first to third sound-generating modules 500-1, 500-2, and 500-3 depending on the structure of the final product. For example, a display device according to another embodiment of the present specification may be configured to include the first and second sound-generating modules 500-1 and 500-2, but not the third sound-generating module 500-3, of the first to third sound-generating modules 500-1, 500-2, and 500-3. For example, as shown in Figures 18 and 20, the first and second sound generating modules 500-1, 500-2 each having a vibration device 530 are housed and arranged in the first and second module housing sections 370a, 370b provided in the rear cover 1300, respectively, and vibrate the display module 100, for example, the first and second areas of the display panel 110, respectively, so that two-channel stereo sound consisting of left sound (LS) and right sound (RS) can be output by the vibration of the first and second areas of the display panel 110.

[0291] In addition, in a display device according to another embodiment of the present specification, the third sound-generating module 500-3 is not accommodated or inserted in the third module accommodating portion 370c provided in the rear cover 1300, and the third module accommodating portion 370c is left open, which can cause problems associated with changes in sound pressure due to a gap space between the rear cover 1300 and the display module 100 overlapping the third module accommodating portion 370c, and can also reduce the heat dissipation characteristics of the display module 100 overlapping the third module accommodating portion 370c. To prevent these problems, the display device according to another embodiment of the present specification may further include a cover 900.

[0292] The cover 900 may be a cover structure for covering a module accommodating portion that does not insert (or accommodate) the third sound-generating module 500-3. The cover 900 according to some examples herein may have substantially the same structure as the module structure 2510 of the sound-generating modules 500-1, 500-2, and 500-3, and may not include a vibration device, unlike the sound-generating modules 500-1, 500-2, and 500-3. For example, the cover 900 may include the frame portion 511, bottom portion 513, and inclined portion 515 of the module structure 2510 shown in FIG. 15. For example, the rear surface of the cover 900 is disposed on or fixed to the second rear cover 350 exposed by the third module accommodating portion 370c via a first member 910 (or a cover fixing member). The front surface of the cover 900 is connected to the rear surface of the display module 100 via a cover adhesive member 920. In this way, the cover 900 covers the third module accommodating portion 370c that does not accommodate the third sound generating module 500-3, thereby preventing problems caused by opening the third module accommodating portion 370c. The cover 900 may be a hole cover, a cap, a lid, or the like, and is not limited to these terms.

[0293] As another example, a display device according to another embodiment of the present specification may be configured not to include any of the first to third sound-generating modules 500-1, 500-2, and 500-3, depending on the structure of the final product. For example, as shown in Figures 18 and 21, a display device according to another embodiment of the present specification does not house the sound-generating modules 500-1, 500-2, and 500-3 in the first to third module housing portions 370a, 370b, and 370c provided in the rear cover 300, respectively, and the first to third module housing portions 370a, 370b, and 370c are open, respectively, which may reduce the heat dissipation characteristics of the display module 100 overlapping the first to third module housing portions 370a, 370b, and 370c, respectively. In order to prevent such problems, a display device according to another embodiment of the present specification further includes first to third covers 900-1, 900-2, and 900-3 that are housed in the first to third module housing portions 370a, 370b, and 370c, respectively.

[0294] Each of the first to third covers 900-1, 900-2, and 900-3 has substantially the same structure as the module structure 2510 of the sound-generating modules 500-1, 500-2, and 500-3, but does not include a vibration device, unlike the sound-generating modules 500-1, 500-2, and 500-3. For example, each of the first to third covers 900-1, 900-2, and 900-3 is disposed on or fixed to the second rear cover 350 exposed by each of the first to third module accommodating portions 370a, 370b, and 370c via a first member 910 (or a cover fixing member). The front surfaces of each of the first to third covers 900-1, 900-2, and 900-3 are disposed on or connected to the rear surface of the display module 100 via a cover adhesive member 920. As a result, the first to third covers 900-1, 900-2, 900-3 cover the first to third module accommodating sections 370a, 370b, 370c, respectively, into which the sound-generating modules 500-1, 500-2, 500-3 are not accommodated or inserted, thereby preventing problems caused by opening the first to third module accommodating sections 370a, 370b, 370c. Therefore, the rear cover 1300 according to the embodiment of the present specification includes a plurality of module accommodating sections 370a, 370b, 370c to which the sound-generating modules 500-1, 500-2, 500-3 and the cover 900 are selectively attached depending on the structure of the final product, and thus can be used in common regardless of the final product structure of the display device.

[0295] FIG. 22 is a diagram showing a display device according to another embodiment of the present specification.

[0296] 22 , a display device according to another embodiment of the present disclosure may include at least one sound-generating module 500 disposed on the rear surface of the rear cover 300. The at least one sound-generating module 500 may be disposed and accommodated in at least one module accommodating portion 370 provided in the rear cover 300. The at least one sound-generating module 500 may be attached to the rear cover 300.

[0297] At least one module receiving portion 370 provided in the rear cover 300 is the same as the module receiving portion shown in FIGS. 10 and 11, and therefore a duplicated description thereof will be omitted.

[0298] The at least one sound-generating module 500 may be modularized as a single component and accommodated in at least one module accommodating portion 370 provided in the rear cover 300. According to some examples herein, the at least one sound-generating module 500 may be accommodated in at least one module accommodating portion 370 provided in the first rear cover 310 of the rear cover 300 and supported on the rear surface of the first rear cover 310. For example, the at least one sound-generating module 500 may have a box structure having a frame (or boundary) with one side open. The at least one sound-generating module 500 may indirectly vibrate the display module 100, thereby generating sound (PVS) due to vibration of the display module 100, for example, the display panel 110.

[0299] Therefore, in the display device according to another embodiment of the present specification, at least one sound-generating module 500 is accommodated in the module accommodating portion 370 formed in the rear cover 300, thereby reducing the thickness by the height (or depth) of the module accommodating portion 370 and the weight by the size of the module accommodating portion 370. In the display device according to another embodiment of the present specification, the sound-generating module 500 is arranged on the rear side of the rear cover 300, which may simplify the assembly process between the sound-generating module 500 and the rear cover 300.

[0300] 23A to 23D are diagrams showing plates according to other embodiments of the present specification.

[0301] Referring to Figures 23A-23D, a plate can be applied to a diaphragm to generate sound.

[0302] For example, FIG. 23A may be glass 601, and a sound generating module such as one of FIGS. 3A to 3E, 5, 6, and 14 to 16B may be disposed on the rear surface of the glass 601 to realize a sound plate capable of outputting sound. Alternatively, a sound generating module or sound generating device such as one of FIGS. 24A to 46B, which will be described later, may be disposed on the rear surface of the glass 601. For example, the glass 601 may be configured in the form of a picture frame. A sound generating module may be disposed on the rear surface of the picture frame, which contains a photograph or picture, allowing sound to be heard while viewing the photograph or image.

[0303] As another example, as shown in Figure 23B, a sound plate can be realized using wood 602. For example, a sound plate that can output sound can be realized by placing a sound generating module such as those shown in Figures 3A to 3E, 5, 6, and 14 to 16B on the back of wood 602. Alternatively, a sound generating module or sound generating device such as those shown in Figures 24A to 46B, which will be described later, can be placed on the back of tree 602.

[0304] As another example, as shown in Figure 23C, a sound plate can be realized using plastic 603. For example, a sound plate capable of outputting sound can be realized by arranging the sound generating module shown in Figures 3A to 3E, 5, 6, and 14 to 16B on the back surface of plastic 603. Alternatively, a sound generating module or sound generating device shown in Figures 24A to 46B, which will be described later, can be arranged on the back surface of plastic 603.

[0305] As another example, as shown in FIG. 23D, a sound plate can be realized using metal 604. The metal can be, but is not limited to, a metal injection molding. For example, a sound plate capable of outputting sound can be realized by arranging a sound generating module such as those shown in FIGS. 3A to 3E, 5, 6, and 14 to 16B on the back surface of the metal 604. Alternatively, a sound generating module or sound generating device such as those shown in FIGS. 24A to 46B, which will be described later, can be arranged on the back surface of the metal 604.

[0306] As another example, a projector screen or video playback device and / or the sound generating modules of Figures 3A to 3E, 5, 6, and 14 to 16B may be disposed to output sound, thereby providing a user with stereo sound. As another example, a device such as a Bluetooth device may be disposed to output sound, thereby providing a user with sound.

[0307] As another example, when a sound generating module having multiple channels as shown in Figures 23A to 23D, a video playback device, or a Bluetooth device is configured, it is possible to provide the user with stereophonic sound and realistic three-dimensional sound.

[0308] As another example, when a film-type or piezoelectric composite sound generating module as shown in Figures 33 to 44C (described later) is configured on a projector screen, video playback device, or Bluetooth device as shown in Figures 23A to 23D, a thin vibration device can be configured, and stereo sound and realistic three-dimensional sound can be provided to the user.

[0309] Therefore, according to another embodiment of the present specification, by applying a sound generating module modularized with a sound plate, it is possible to provide images and stereo sound, thereby improving the user's sense of immersion and providing realistic stereo sound.

[0310] When the sound-generating module described with reference to FIGS. 1 to 23D is applied to a display device, sound-generating modules can be configured in at least two of the three regions. For example, sound-generating modules can be arranged in the left and right regions of the display device, outputting left and right sounds in front of the display panel. For example, we recognized the problem that sound can be output in the left and right directions of the display panel, but sound cannot be output in the up and down directions of the display panel. To improve sound in the up and down directions of the display panel, multiple sound-generating modules can be arranged, but this increases the thickness of the display device. Furthermore, additional speakers for outputting stereophonic sound can be arranged around the display device. Since the distance from the speaker to the user needs to be adjusted according to the desired frequency, there is a problem in that the speakers must be positioned depending on the user's position or the position of the image. Therefore, the inventors of this specification conducted several experiments to realize a sound-generating module that can generate left and right sounds and up and down sounds according to the image without increasing the thickness of the display device. Through multiple experiments, we invented a display device including a sound-generating module with a new structure that can generate left and right sounds and up and down sounds. This will be described with reference to FIGS. 24A to 44C.

[0311] 24A and 24B are diagrams illustrating a display device including a sound-generating module according to an embodiment of the present disclosure.

[0312] 24A and 24B, a display device may include a plate including a first region 1, a second region 2, a third region 3, a fourth region 4, and a fifth region 5. The plate may be a display panel that displays images, and the following description will be given using an example in which the plate is a display panel. As another example, the plate may be made of one of glass, wood, plastic, and metal, as described with reference to FIGS. 23A to 23D. As another example, a display device may further include a second plate that includes a first region 1, a second region 2, a third region 3, a fourth region 4, and a fifth region 5, and the second plate may be made of one of glass, wood, plastic, and metal. In this case, the plate may be a display panel that displays images, and a sound generating device or sound generating module may be disposed on the second plate that includes the first region 1, the second region 2, the third region 3, the fourth region 4, and the fifth region 5. In this configuration, the plate may display images, and the second plate may be a sound plate that outputs sound.

[0313] The rear surface of the display panel 110 may include a first region 1 to a fifth region 5. For example, the first region 1 and the fourth region 4 may be a region on the left side of the rear surface of the display panel 110. For example, the second region 2 and the fifth region 5 may be a region on the right side of the rear surface of the display panel 110. For example, the third region 3 may be a central region on the rear surface of the display panel 110. As another example, as described with reference to FIG. 22, when the sound-generating module is disposed on the rear surface of the rear cover 300, the first region 1 to the fifth region 5 may be regions on the rear surface of the rear cover 300. The same or similar description can be applied to FIGS. 26A to 32E and 41A to 44C. The following embodiments will be described taking the case where the sound-generating module is disposed on the rear surface of the display panel as an example, but are not limited thereto and the sound-generating module may be disposed on the rear surface of the rear cover.

[0314] At least one sound-generating module may be arranged in at least one of the first region 1, the second region 2, the third region 3, the fourth region 4, and the fifth region 5. The at least one sound-generating module may be the sound-generating module or the vibration device described with reference to Figures 1 to 22. The vibration device may be a vibration device including a voice coil.

[0315] For example, the fourth sound-generating module 1500HL may be disposed in the fourth region 4 on the rear surface of the display panel 110. The first woofer-integrated sound-generating module (W1) may be disposed in the first region 1 on the rear surface of the display panel 110. The fifth sound-generating module 1500HR may be disposed in the fifth region 5 on the rear surface of the display panel 110, and the second woofer-integrated sound-generating module (W2) may be disposed in the second region 2 on the rear surface of the display panel 110. The third sound-generating module 1500C may be disposed in the third region 3 on the rear surface of the display panel 110. The fourth sound-generating module 1500HL may be the top left channel of the display panel 110, and the fifth sound-generating module 1500HR may be the top right channel of the display panel 110. The third sound-generating module 1500C may be the center channel of the display panel 110.

[0316] The first woofer-integrated sound-generating module (W1) and the second woofer-integrated sound-generating module (W2) are sound-generating modules integrated with woofers, which has the advantage of eliminating the need for separate woofers. The first woofer-integrated sound-generating module (W1) and the second woofer-integrated sound-generating module (W2) may be sound-generating modules that include woofers. The first woofer-integrated sound-generating module (W1) and the second woofer-integrated sound-generating module (W2) will be described later with reference to Figures 25A and 25B.

[0317] The first woofer-integrated sound-generating module (W1) and the second woofer-integrated sound-generating module (W2) can output sound in the range of 60 Hz to 40 kHz, and the third sound-generating module 1500C, the fourth sound-generating module 1500HL, and the fifth sound-generating module 1500HR can output sound in the range of 80 Hz to 40 kHz. Therefore, the display device can output 3.2-channel sound.

[0318] Compared to sound generating modules arranged on the left and right sides of the display panel, sound generating modules arranged above and below the display panel can improve left-right and up-down sounds, providing the user with a sound field similar to that of real sound. For example, by further configuring a fourth sound generating module 1500HL and a fifth sound generating module 1500HR, sound can be output from the upper side of the display panel 110, thereby providing a display device that can realize three-dimensional sound including left-right and up-down sounds. Therefore, left-right and up-down sounds can be realized for left-right images and up-down images, and real stereophonic sound (e.g., real sound) including three-dimensional left-right and up-down sounds can be realized for the user, providing real sound rather than virtual sound. This allows the user to realize real stereophonic sound or surround sound (e.g., real sound) including three-dimensional left-right and up-down sounds, thereby improving the sense of presence. Therefore, even in movie theaters, private movie theaters, and devices such as televisions, users can simultaneously experience sounds and images that are similar to or identical to reality, for example, they can experience a realistic AV (AudioVisual) or Dolby sound system.

[0319] Furthermore, when the sound generating module having the multi-channels shown in FIGS. 24A and 24B is implemented on the sound plate of FIGS. 23A to 23D, it is possible to realize real stereophonic sound or surround sound that includes stereophonic left and right sounds and stereophonic sounds above and below, thereby improving the sense of realism. When the sound generating module having the multi-channels shown in FIGS. 24A and 24B is implemented on the sound plate of FIGS. 23A to 23D and a projector or video playback device are respectively configured, it is possible to provide a realistic AV (AudioVisual) or Dolby sound system, for example, so that the user can experience real sound and video simultaneously in a manner similar to or identical to reality, thereby providing immersive and realistic stereophonic sound. Furthermore, as described with reference to FIGS. 1 to 22, applying a modularized sound generating module can improve the design freedom of the display device or rear cover when arranging the sound generating module.

[0320] For example, the fourth sound-generating module 1500HL may be arranged symmetrically with the fifth sound-generating module 1500HR, but is not limited thereto. For example, the fourth sound-generating module 1500HL may be arranged collinearly with the fifth sound-generating module 1500HR, but is not limited thereto. For example, the first woofer-integrated sound-generating module (W1) may be arranged symmetrically with the second woofer-integrated sound-generating module (W2), but is not limited thereto. For example, the first woofer-integrated sound-generating module (W1) may be arranged collinearly with the second woofer-integrated sound-generating module (W2), but is not limited thereto. For example, the first woofer-integrated sound-generating module (W1) and the second woofer-integrated sound-generating module (W2) may be arranged symmetrically with the third sound-generating module 1500C, but is not limited thereto. For example, the first woofer-integrated sound-generating module (W1) and the second woofer-integrated sound-generating module (W2) can be arranged in the same line as the third sound-generating module 1500C, but is not limited thereto.

[0321] 24B, the first woofer-integrated sound-generating module (W1) and the second woofer-integrated sound-generating module (W2) may be arranged asymmetrically with respect to the third sound-generating module 1500C, but the embodiments herein are not limited thereto. For example, the first woofer-integrated sound-generating module (W1) and the second woofer-integrated sound-generating module (W2) may be arranged on a different line from the third sound-generating module 1500C, but the embodiments herein are not limited thereto. When configured in this manner, the first woofer-integrated sound-generating module (W1) is separated from the fourth sound-generating module 1500HL in the fourth area 4, so that sound from the underside of the display panel 110 can be more clearly reproduced by the first woofer-integrated sound-generating module (W1), and the distance between the first woofer-integrated sound-generating module (W1) and the fourth sound-generating module 1500HL makes it possible to realize sound that allows the difference between the sound of the first woofer-integrated sound-generating module (W1) and the sound of the fourth sound-generating module 1500HL to be distinguished. Furthermore, since the second woofer-integrated sound-generating module (W2) is separated from the fifth sound-generating module 1500HR in the fifth area 5, the second woofer-integrated sound-generating module (W2) can more clearly reproduce sound from the underside of the display panel 110, and the distance between the second woofer-integrated sound-generating module (W1) and the fifth sound-generating module 1500HR makes it possible to realize sound that allows the difference between the sound of the second woofer-integrated sound-generating module (W2) and the sound of the fifth sound-generating module 1500HR to be distinguished.

[0322] 24A and 24B, the first woofer-integrated sound-generating module (W1) may be disposed asymmetrically with the fourth sound-generating module 1500HL. The second woofer-integrated sound-generating module (W2) may be disposed asymmetrically with the fifth sound-generating module 1500HR. This configuration can reduce acoustic reinforcement or cancellation due to vibration interference between the vibrations and standing waves generated by the first woofer-integrated sound-generating module (W1) and the vibrations and standing waves generated by the fourth sound-generating module 1500HL. In addition to vibrations from the sound source being reproduced, unwanted acoustic reinforcement or cancellation due to external interference can cause sound distortion and degradation of sound quality. However, the asymmetric structure of the first woofer-integrated sound-generating module (W1) and the fourth sound-generating module 1500HL prevents this, allowing for the reproduction of natural sound that is closer to the original sound. This reduces acoustic reinforcement or cancellation caused by vibration interference between the vibrations and standing waves generated by the second woofer-integrated sound-generating module (W2) and the vibrations and standing waves generated by the fifth sound-generating module 1500HR. In addition to vibrations from the sound source being reproduced, unwanted acoustic reinforcement or cancellation due to external interference can cause sound distortion and deterioration in sound quality. However, the asymmetric structure of the second woofer-integrated sound-generating module (W2) and the fifth sound-generating module 1500HR prevents this and reproduces natural sound closer to the original sound. As another example, the first woofer-integrated sound-generating module (W1) can be arranged symmetrically with the fourth sound-generating module 1500HL. The second woofer-integrated sound-generating module (W2) can be arranged symmetrically with the fifth sound-generating module 1500HR. This configuration allows the sound reproduction positions to be aligned on the same line, providing the effect of sound being reproduced from the same position compared to an asymmetric structure. This can improve the sense of awareness of the position of the sound, and can improve the sense of sound localization.

[0323] As another example, at least one of the fourth sound-generating module 1500HL and the fifth sound-generating module 1500HR may be configured as a sound-generating module including a woofer. For example, a first woofer-integrated sound-generating module (W1) may be configured in the fourth region 4, and a second woofer-integrated sound-generating module (W2) may be configured in the fifth region 5. For example, a sound-generating module including a woofer may be configured in one or more of the fourth region 4 and the fifth region 5. As another example, a sound-generating module including a woofer may be configured in the third region 3. For example, the third sound-generating module 1500C may be configured as a sound-generating module including a woofer. Therefore, by arranging a sound-generating module including a woofer in one or more of the first region 1, the second region 2, the third region 3, the fourth region 4, and the fifth region 5, low-frequency sound can be output, thereby providing a display device that can output low-, mid-, and high-frequency sound. In this configuration, the sound-generating modules can be driven by applying the same signal or a mono signal.

[0324] 25A and 25B are diagrams illustrating a sound-generating module according to another embodiment of the present disclosure.

[0325] The sound-generating module 1800 according to other embodiments of the present specification may be a woofer-integrated sound-generating module, a hybrid sound-generating module, or a sound-generating module including a woofer, and is not limited to these terms. Fig. 25A is a front view of the sound-generating module, and Fig. 25B is a cross-sectional view of the sound-generating module.

[0326] 25A and 25B, the sound-generating module 1800 may include a first sound-generating device 1801 and a second sound-generating device 1802. For example, the first sound-generating device 1801 may be disposed behind the display panel, and the second sound-generating device 1802 may be spaced apart from the rear of the display panel.

[0327] The sound generating module 1800 may include a frame that can accommodate the first sound generating device 1801 and the second sound generating device 1802. The frame may include a lower frame 1610a that supports the undersides of the first sound generating device 1801 and the second sound generating device 1802 and a side frame 1610b that connects to the lower frame 1610a. The frame may be a yoke, and is not limited to the term.

[0328] The lower frame 1610a can support the magnet 1620. The magnet 1620 can be shared by the first sound generator 1801 and the second sound generator 1802. For example, the bobbin 1650a of the first sound generator 1801 and the coil 1660a around the bobbin 1650a can be arranged around the magnet 1620. For example, the second bobbin 1650b of the second sound generator 1802 and the second coil 1660b around the second bobbin 1650b can be arranged around the magnet 1620. For example, the lower frame 1610a and the plate 1611 can be arranged below and above the magnet 1620, respectively, to increase the magnetic flux density formed through the magnet 1620 and the coil 1660a and the second coil 1660b, thereby improving vibration characteristics. The lower frame 1610a can be a yoke, but the term is not limited to this.

[0329] The side frame 1610b is connected to the lower frame 1610a and may include at least one hole 217 for sound discharge. For example, the hole 217 may be a vent. For example, the hole 217 may be an air gap inside the sound-generating module 1800, through which low-frequency sound generated by the diaphragm 214b of the second sound-generating device 1802 may be output to the rear of the display panel 110.

[0330] The side frame 1610b is made of a conductive material and can control the magnetic flux generated by the magnet 1620. For example, the side frame 1610b surrounds the magnet 1620 at a distance, thereby concentrating the magnetic flux generated by the magnet 1620 within the second bobbin 1650b and suppressing leakage magnetic flux. The side frame 1610b may be a yoke, but is not limited to the term. The holes 217 may be formed not only in the side frame 1610b but also in the lower frame 1610a, and may be formed in the area where the side frame 1610b and the lower frame 1610a are connected. The side frame 1610b may be connected to the rear cover via a connecting member 1710, such as a nut, or may be disposed between the side frame 1610b and the display panel 110.

[0331] The first sound-generating device 1801 may include a magnet 1620 disposed on a frame, a bobbin 1650a around the magnet 1620, and a coil 1660a and a damper 1670a around the bobbin 1650a, etc. For example, the description thereof is similar to that described in FIGS. 3A to 3E, 6, and 14, and therefore detailed description thereof will be omitted or simplified here.

[0332] The magnet 1620 may be disposed on the lower frame 1610a. For example, the magnet 1620 may be interposed between the plate 1611 and the lower frame 1610a. The lower frame 1610a and the plate 1611 may control the magnetic flux generated by the magnet 1620. For example, by surrounding the magnet 1620 with the lower frame 1610a and the plate 1611, the magnetic flux generated by the magnet 1620 may be concentrated within the bobbin 1650a, thereby suppressing leakage magnetic flux.

[0333] The bobbin 1650a may be attached to the rear surface of the bobbin ring 1652a. For example, when a current for generating sound is applied to the coil 1660a wound around the outer periphery of the bobbin 1650a, a magnetic field is formed within the first sound generating device 1801. The magnetic field can vibrate the display panel via the bobbin ring 1652a. The bobbin ring 1652a is interposed between the bobbin 1650a and the display panel, and can transmit the vibration of the bobbin 1650a to the display panel. The first sound generating device 1801 can output mid- to high-frequency sounds.

[0334] The second acoustic generating device 1802 may include a magnet 1620 arranged on the frame, a plate 1611 on the magnet 1620, a second bobbin 1650b around the magnet 1620, and a second coil 1660b and a second damper 1670b around the second bobbin 1650b.

[0335] A diaphragm 214b may be disposed on the second bobbin 1650b. For example, the diaphragm 214b may be spaced apart from the rear surface of the display panel to block heat generated in the second bobbin 1650b from being transferred to the display panel.

[0336] When a sound-generating current is applied to the coil 1660b wound around the outer periphery of the second bobbin 1650b, a magnetic field is formed within the second sound-generating device 1802. The magnetic field vibrates the air layer or air gap around the diaphragm 214b via the diaphragm 214b, thereby outputting sound. For example, the front surface of the second bobbin 1650b contacts the diaphragm 214b and can vibrate the diaphragm 214b depending on whether or not a current is applied. The second sound-generating device 1802 can output sound to the front and rear of the diaphragm 214b. For example, the second sound-generating device 1802 can output sound in the low-frequency range. For example, the sound generated by the diaphragm 214b of the second sound-generating device 1802 can include a first low-pitched sound propagated to the upper side of the diaphragm 214b and a second low-pitched sound propagated to the lower side of the diaphragm 214b. For example, the second sound generating device 1802 may be a woofer, and is not limited to the term.

[0337] The magnet 1620 may be disposed on the lower frame 1610a. The plate 1611 may be spaced apart from the diaphragm 214b. The second bobbin 1650b may be disposed on the rear surface of the diaphragm 214b. For example, the second bobbin 1650b may surround the magnet 1620 and the plate 1611.

[0338] The second damper 1670b may be disposed between the first sound-generating device 1801 and the second sound-generating device 1802. For example, the second damper 1670b may be disposed between the damper 1670a of the first sound-generating device 1801 and the second bobbin 1650b of the second sound-generating device 1802. For example, the second damper 1670b may be disposed between the diaphragm 214b of the first sound-generating device 1801 and the diaphragm 214b of the second sound-generating device 1802. The diaphragm 214b may not be in physical contact with the first sound-generating device 1801. For example, the second damper 1670b may prevent acoustic interference between the first sound-generating device 1801 and the second sound-generating device 1802. An edge 1670c may be disposed on the diaphragm 214b. The edge 1670c can prevent deformation such as distortion of the diaphragm 214b when the diaphragm 214b moves up and down, thereby providing clear sound quality and improving the reliability of the sound generating module 1800. The second damper 1670b can be a first suspension, and the edge 1670c can be a second suspension.

[0339] The magnet 1620 of the first sound generating device 1801 and the magnet 1620 of the second sound generating device 1802 may have magnetic fields in opposite directions. The first sound generating device 1801 can directly vibrate the display panel to output high-frequency sound to the front of the display panel, and the second sound generating device 1802 can output low-frequency sound to the rear of the display panel. Therefore, the first sound generating device 1801 and the second sound generating module have magnetic fields in opposite directions, which allows the vibrations of the first sound generating device 1801 and the second sound generating device 1802 to be driven or controlled independently.

[0340] Therefore, the woofer-integrated sound-generating module may include a woofer disposed around the sound-generating module. The sound-generating module is disposed behind the display panel to generate mid- to high-frequency sounds, and the woofer is disposed at a distance from the rear of the display panel to generate low-frequency sounds by vertical vibration. For example, the sound-generating module and the woofer may be driven by applying different acoustic signals or voice signals. Therefore, the woofer-integrated sound-generating module may improve low-frequency sounds.

[0341] 26A and 26B are diagrams showing a display device including a sound generating module according to another embodiment of the present specification.

[0342] 26A and 26B, at least one sound-generating module may be arranged in at least one of the first region 1, the second region 2, the third region 3, the fourth region 4, and the fifth region 5. For example, the first sound-generating module 1500L may be arranged in the first region 1 on the rear surface of the display panel 110, and the fourth sound-generating module 1500HL may be arranged in the fourth region 4 on the rear surface of the display panel 110. The second sound-generating module 1500R may be arranged in the second region 2 on the rear surface of the display panel 110, and the fifth sound-generating module 1500HR may be arranged in the fifth region 5 on the rear surface of the display panel 110. The third sound-generating module 1500C may be arranged in the third region 3 on the rear surface of the display panel 110. As another example, the first to fifth sound-generating modules may be arranged on the rear surface of the rear cover 300, as described in FIG. 22. For example, the first to fifth sound-generating modules may be arranged in a modular structure.

[0343] The first sound-generating module 1500L may be the left channel of the display panel 110, and the fourth sound-generating module 1500HL may be the height left channel of the display panel 110. The second sound-generating module 1500R may be the right channel of the display panel 110, and the fifth sound-generating module 1500HR may be the height right channel of the display panel 110. The third sound-generating module 1500C may be the center channel of the display panel 110.

[0344] 26A and 26B, the first sound-generating module 1500L may be arranged symmetrically with the fourth sound-generating module 1500HL, but is not limited to this arrangement. For example, the first sound-generating module 1500L may be arranged on the same line as the fourth sound-generating module 1500HL, but is not limited to this arrangement. In this configuration, the sound reproduction positions may be arranged on the same line, giving the effect of sounds being reproduced from the same position. This may improve the sense of awareness of the sound position, and therefore the sense of sound localization. For example, the second sound-generating module 1500R may be arranged symmetrically with the fifth sound-generating module 1500HR, but is not limited to this arrangement. For example, the second sound-generating module 1500R may be arranged on the same line as the fifth sound-generating module 1500HR, but is not limited to this arrangement. In this configuration, the sound reproduction positions may be arranged on the same line, giving the effect of sounds being reproduced from the same position. This may improve the sense of awareness of the sound position, and therefore the sense of sound localization. For example, the first sound-generating module 1500L and the fourth sound-generating module 1500HL can be arranged symmetrically with the second sound-generating module 1500R and the fifth sound-generating module 1500HR, but are not limited thereto. The first sound-generating module 1500L and the fourth sound-generating module 1500HL can be arranged collinearly with the second sound-generating module 1500R and the fifth sound-generating module 1500HR, but are not limited thereto.

[0345] 26A, the first sound-generating module 1500L and the second sound-generating module 1500R may be arranged on the same line as the third sound-generating module 1500C, but the embodiments of this specification are not limited to this. In this configuration, the sound reproduction positions may be arranged on the same line, giving the impression that the sounds are being reproduced from the same position. This may improve the perception of the sound position, thereby improving the sense of sound localization.

[0346] 26B , the first sound-generating module 1500L and the second sound-generating module 1500R can be arranged asymmetrically with respect to the third sound-generating module 1500C, although examples herein are not limited thereto. For example, the first sound-generating module 1500L and the second sound-generating module 1500R can be arranged on a different line from the third sound-generating module 1500C, although examples herein are not limited thereto. For example, the first sound-generating module 1500L and the second sound-generating module 1500R can be arranged on the same line. For example, the third sound-generating module 1500C can be arranged on a different line from the first sound-generating module 1500L. For example, the third sound-generating module 1500C can be arranged on a different line from the second sound-generating module 1500R. With this configuration, the first sound-generating module 1500L is spaced apart from the fourth sound-generating module 1500HL in the fourth region 4, so that sound from below the display panel 110 can be more clearly generated by the first sound-generating module 1500L, and the distance between the first sound-generating module 1500L and the fourth sound-generating module 1500HL makes it possible to realize sound that allows the difference between the sound of the first sound-generating module 1500L and the sound of the fourth sound-generating module 1500HL to be distinguished. Furthermore, the second sound-generating module 1500R is spaced apart from the fifth sound-generating module 1500HR in the fifth region 5, so that sound from below the display panel 110 can be more clearly generated than by the second sound-generating module 1500R, and the distance between the second sound-generating module 1500R and the fifth sound-generating module 1500HR makes it possible to realize sound that allows the difference between the sound of the second sound-generating module 1500R and the sound of the fifth sound-generating module 1500HR to be distinguished.

[0347] A fourth sound-generating module 1500HL can be configured in the fourth region 4 and a fifth sound-generating module 1500HR can be configured in the fifth region 5, and no sound-generating module can be configured in the sixth region 6 between the fourth region 4 and the fifth region 5. This allows the vibrations of the fourth sound-generating module 1500HL and the fifth sound-generating module 1500HR to be attenuated or absorbed in the sixth region 6 of the display panel 110, thereby blocking or reducing the transmission of sound from the fourth region 4 to the fifth region 5, and blocking or reducing the transmission of sound from the fifth region 5 to the fourth region 4. This reduces the deterioration in sound quality caused by interference between the sounds generated by the fourth sound-generating module 1500HL and the fifth sound-generating module 1500HR, and has the effect of further improving the acoustic characteristics in the mid- to high-frequency range.

[0348] Therefore, the first sound-generating module 1500L and the fourth sound-generating module 1500HL are arranged in a first region 1 and a fourth region 4, which are left regions on the rear surface of the display panel 110, and can vibrate the left region of the display panel 110. The second sound-generating module 1500R and the fifth sound-generating module 1500HR are arranged in a second region 2 and a fifth region 5, which are right regions on the rear surface of the display panel 110, and can vibrate the right region of the display panel 110. The third sound-generating module 1500C is arranged in a third region 3, which is a central region on the rear surface of the display panel 110, and can vibrate the central region of the display panel 110. The first sound-generating module 1500L, the second sound-generating module 1500R, the third sound-generating module 1500C, the fourth sound-generating module 1500HL, and the fifth sound-generating module 1500HR can each receive a different vibration signal and be driven independently. For example, the first sound-generating module 1500L and the fourth sound-generating module 1500HL can generate sound by using the left region of the back surface of the display panel 110 as a diaphragm, the second sound-generating module 1500R and the fifth sound-generating module 1500HR can generate sound by using the right region of the back surface of the display panel 110 as a diaphragm, and the third sound-generating module 1500C can generate sound by using the central region of the display panel 110 as a diaphragm.

[0349] The display device according to the embodiments of the present specification may include woofers to further improve low-frequency sound. For example, at least one or more woofers may be further disposed below at least one of the first sound-generating module 1500L and the second sound-generating module 1500R. For example, at least one or more woofers may be further disposed below at least one of the first region 1 and the second region 2. For example, the first woofer (W3) may be disposed below (or below) the first region 1 of the display panel 110. For example, the first woofer (W3) may be disposed below (or below) the first sound-generating module 1500L. For example, the second woofer (W4) may be disposed below (or below) the second region 2 of the display panel 110. For example, the second woofer (W4) may be disposed below (or below) the second sound-generating module 1500R. Therefore, the first woofer (W3) and the second woofer (W4) can output low-frequency sound. The first sound-generating module 1500L, the second sound-generating module 1500R, the third sound-generating module 1500C, the fourth sound-generating module 1500HL, and the fifth sound-generating module 1500HR can output sounds in the range of 80 Hz to 40 kHz, and the first woofer (W3) and the second woofer (W4) can output sounds below 80 Hz. Therefore, the display device can output 5.1 channel sounds.

[0350] Furthermore, because sound generating modules are further configured above and below the horizontal direction of the display panel in comparison with the sound generating modules arranged on the left and right, left and top sounds can be improved, providing the user with a sound field similar to that of real sound. For example, by further configuring a fourth sound generating module 1500HL and a fifth sound generating module 1500HR, sound can be output from the upper side of the display panel 110 or output to the upper side of the display panel 110, thereby providing a display device that can realize three-dimensional sound including left and right sounds and top and bottom sounds. Therefore, left and right sounds and top and bottom sounds can be realized for left and right images and top and bottom images, and real stereophonic sound (e.g., real sound) including three-dimensional left and right sounds and top and bottom sounds can be realized for the user, providing real sound rather than virtual sound. This allows the user to realize real stereophonic sound or surround sound (e.g., real sound) including three-dimensional left and right sounds and top and bottom sounds, thereby improving the sense of presence. Therefore, even in movie theaters, private cinemas, and devices such as televisions, users can experience real sound and images at once that are similar to or identical to reality, for example, they can experience a realistic AV (AudioVisual) or Dolby sound system.

[0351] Furthermore, when the sound generating module having the multi-channels of FIGS. 24A and 24B is implemented on the sound plate of FIGS. 23A to 23D, it is possible to realize a real stereophonic sound or surround sound that is an actual sound (e.g., real sound) including stereophonic left and right sounds and stereophonic sounds above and below, thereby improving the sense of realism. When the sound generating module having the multi-channels of FIGS. 24A and 24B is implemented on the sound plate of FIGS. 23A to 23D and a projector or video playback device, respectively, it is possible to provide a realistic AV (AudioVisual) or Dolby sound system, for example, so that the user can experience real sound and video simultaneously in a manner similar to or identical to reality, thereby providing immersive and realistic stereophonic sound. Furthermore, as described with reference to FIGS. 1 to 22, applying a modularized sound generating module can improve the design flexibility of the display device or rear cover when arranging the sound generating module.

[0352] FIG. 27 is a diagram showing a display device including a sound generating module according to another embodiment of the present specification.

[0353] Referring to FIG. 27, the display panel 110 may include a first region 1 to an eleventh region 11. For example, the first region 1, the fourth region 4, and the seventh region 7 may be left regions on the rear surface of the display panel 110. For example, the second region 2, the fifth region 5, and the eighth region 8 may be right regions on the rear surface of the display panel 110. For example, the third region 3, the sixth region 6, and the ninth region 9 may be central regions on the rear surface of the display panel 110. For example, the sixth region 6 may be a region between the fourth region 4 and the fifth region 5. For example, the ninth region 9 may be a region between the seventh region 7 and the eighth region 8. For example, the tenth region 10 may be a region between the first region 1 and the third region 3. For example, the eleventh region 11 may be a region between the second region 2 and the third region 3. For example, the seventh region 7 may be below the first region 1, and the eighth region 8 may be below the second region 2. For example, the tenth region 10 may be the region between the first region 1, the fourth region 4, and the seventh region 7 and the third region 3, the sixth region 6, and the ninth region 9. For example, the eleventh region 11 may be the region between the second region 2, the fifth region 5, and the eighth region 8 and the third region 3, the sixth region 6, and the ninth region 9. The numbers 1 to 11 indicating the regions in the first to eleventh regions are arbitrary, and the numbers 1 to 11 and the division of the first to eleventh regions do not limit the contents of the specification. The explanation therefor can be applied identically or similarly to Figures 28 to 44C.

[0354] At least one sound-generating module may be arranged in at least one of the first region 1 to the eleventh region 11. For example, the first sound-generating module 1500L may be arranged in the first region 1 on the rear surface of the display panel 110, the fourth sound-generating module 1500HL may be arranged in the fourth region 4 on the rear surface of the display panel 110, and the seventh sound-generating module 1500BL may be arranged in the seventh region 7 on the rear surface of the display panel 110. The second sound-generating module 1500R may be arranged in the second region 2 on the rear surface of the display panel 110, the fifth sound-generating module 1500HR may be arranged in the fifth region 5 on the rear surface of the display panel 110, and the eighth sound-generating module 1500BR may be arranged in the eighth region 8 on the rear surface of the display panel 110. The third sound-generating module 1500C can be arranged in a third region 3 on the back surface of the display panel 110, the sixth sound-generating module 1500HC can be arranged in a sixth region 6 on the back surface of the display panel 110, and the ninth sound-generating module 1500BC can be arranged in a ninth region 9 on the back surface of the display panel 110. The tenth sound-generating module 1500LC can be arranged in a tenth region 10 on the back surface of the display panel 110, and the eleventh sound-generating module 1500RC can be arranged in an eleventh region 11 on the back surface of the display panel. As another example, the first to eleventh sound-generating modules can be arranged on the back surface of the rear cover as described in FIG. 22 . For example, the first to eleventh sound-generating modules can be arranged in a modular structure.

[0355] The first sound-generating module 1500L may be the left channel of the display panel 110, the fourth sound-generating module 1500HL may be the height left channel of the display panel 110, and the seventh sound-generating module 1500BL may be the bottom left channel of the display panel 110. The tenth sound-generating module 1500LC may be the left center channel of the display panel 110. The second sound-generating module 1500R may be the right channel of the display panel 110, the fifth sound-generating module 1500HR may be the height right channel of the display panel 110, and the eighth sound-generating module 1500BR may be the bottom right channel of the display panel 110. The eleventh sound-generating module 1500RC may be the right center channel of the display panel 110. The third sound generating module 1500C may be the center channel of the display panel 110, the sixth sound generating module 1500HC may be the height center channel of the display panel 110, and the ninth sound generating module 1500BC may be the bottom center channel of the display panel 110.

[0356] For example, the first sound-generating module 1500L may be arranged symmetrically with the fourth sound-generating module 1500HL and / or the seventh sound-generating module 1500BL, but is not limited thereto. For example, the first sound-generating module 1500L may be arranged on the same line as the fourth sound-generating module 1500HL and / or the seventh sound-generating module 1500BL, but is not limited thereto. In this configuration, the sound reproduction positions can be aligned on the same line, giving the effect of sounds being reproduced from the same position. This can improve the perception of the position of the sound, and therefore the sense of sound localization can be improved.

[0357] For example, the second sound-generating module 1500R may be arranged symmetrically with the fifth sound-generating module 1500HR and / or the eighth sound-generating module 1500BR, but is not limited thereto. For example, the second sound-generating module 1500R may be aligned on the same line as the fifth sound-generating module 1500HR and / or the eighth sound-generating module 1500BR, but is not limited thereto. In this configuration, the sound reproduction positions may be aligned on the same line, giving the effect of sounds being reproduced from the same position. This may improve the perception of the position of the sound, and thus the sense of sound localization may be improved.

[0358] For example, the third sound-generating module 1500C may be arranged symmetrically with the sixth sound-generating module 1500HC and / or the ninth sound-generating module 1500BC, but is not limited thereto. For example, the third sound-generating module 1500C may be aligned on the same line as the sixth sound-generating module 1500HC and / or the ninth sound-generating module 1500BC, but is not limited thereto. In this configuration, the sound reproduction positions may be aligned on the same line, giving the effect of sounds being reproduced from the same position. This may improve the perception of the position of the sound, and thus the sense of sound localization may be improved.

[0359] For example, the tenth sound-generating module 1500LC and the eleventh sound-generating module 1500RC may be arranged symmetrically with at least one of the first sound-generating module 1500L, the second sound-generating module 1500R, and the third sound-generating module 1500C, but this arrangement is not limited thereto. For example, the tenth sound-generating module 1500LC and the eleventh sound-generating module 1500RC may be aligned on the same line with at least one of the first sound-generating module 1500L, the second sound-generating module 1500R, and the third sound-generating module 1500C, but this arrangement is not limited thereto. In this configuration, the sound reproduction positions can be aligned on the same line, creating the effect of sounds being reproduced from the same position. This can improve the perception of the position of the sound, thereby improving the sense of sound localization.

[0360] For example, one of the fourth sound-generating module 1500HL and the fifth sound-generating module 1500HR may be arranged symmetrically with the sixth sound-generating module 1500HC, but this is not a limitation. For example, one of the fourth sound-generating module 1500HL and the fifth sound-generating module 1500HR may be aligned on the same line as the sixth sound-generating module 1500HC, but this is not a limitation. In this configuration, the sound reproduction positions may be aligned on the same line, creating the effect of sounds being reproduced from the same position. This may improve the perception of the sound position, thereby improving the sense of sound localization. For example, one of the first sound-generating module 1500L, the second sound-generating module 1500R, the tenth sound-generating module 1500LC, and the eleventh sound-generating module 1500RC may be arranged symmetrically with the third sound-generating module 1500C, but this is not a limitation. For example, but not limited to, one of the first sound-generating module 1500L, the second sound-generating module 1500R, the tenth sound-generating module 1500LC, and the eleventh sound-generating module 1500RC may be aligned on the same line as the third sound-generating module 1500C. With this configuration, the sound reproduction positions may be aligned on the same line, creating the effect of sounds being reproduced from the same position. This may improve the perception of the sound position, thereby improving the sense of sound localization. For example, but not limited to, one of the seventh sound-generating module 1500BL and the eighth sound-generating module 1500BR may be positioned symmetrically with the ninth sound-generating module 1500BC. For example, but not limited to, one of the seventh sound-generating module 1500BL and the eighth sound-generating module 1500BR may be aligned on the same line as the ninth sound-generating module 1500BC. With this configuration, the sound reproduction positions may be aligned on the same line, creating the effect of sounds being reproduced from the same position. This can improve the perception of the location of the sound, thereby improving the sense of sound localization.

[0361] Therefore, the first sound-generating module 1500L, the fourth sound-generating module 1500HL, and the seventh sound-generating module 1500BL can be arranged in the first region 1, the fourth region 4, and the seventh region 7, which are left regions on the rear surface of the display panel 110, to vibrate the left region on the rear surface of the display panel 110. The second sound-generating module 1500R, the fifth sound-generating module 1500HR, and the eighth sound-generating module 1500BR can be arranged in the second region 2, the fifth region 5, and the eighth region 8, which are right regions on the rear surface of the display panel 110, to vibrate the right region on the rear surface of the display panel 110. The third sound-generating module 1500C, the sixth sound-generating module 1500HC, and the ninth sound-generating module 1500BC can be arranged in the third region 3, the sixth region 6, and the ninth region 9, which are central regions on the rear surface of the display panel 110, to vibrate the central region on the rear surface of the display panel 110. The tenth sound-generating module 1500LC and the eleventh sound-generating module 1500RC are arranged in the tenth region 10 and the eleventh region 11 of the display panel 110, and can vibrate the left region, the center region, and the right region on the rear surface of the display panel 110. The first sound-generating module 1500L, the second sound-generating module 1500R, the third sound-generating module 1500C, the fourth sound-generating module 1500HL, the fifth sound-generating module 1500HR, the sixth sound-generating module 1500HC, the seventh sound-generating module 1500BL, the eighth sound-generating module 1500BR, the ninth sound-generating module 1500BC, the tenth sound-generating module 1500LC, and the eleventh sound-generating module 1500RC can each receive a different vibration signal and be driven independently. For example, the first sound-generating module 1500L, the fourth sound-generating module 1500HL, and the seventh sound-generating module 1500BL can generate sounds by using the left region of the back surface of the display panel 110 as a diaphragm. The second sound-generating module 1500R, the fifth sound-generating module 1500HR, and the eighth sound-generating module 1500BR can generate sounds by using the right region of the back surface of the display panel 110 as a diaphragm.The third sound-generating module 1500C, the sixth sound-generating module 1500HC, and the ninth sound-generating module 1500BC can generate sound by using the central region of the display panel 110 as a diaphragm. The tenth sound-generating module 1500LC and the eleventh sound-generating module 1500RC can generate sound by using the left region, the central region, and the right region of the back surface of the display panel 110 as diaphragms. For example, the sixth sound-generating module 1500HC can generate sound on the upper side of the display panel 110. For example, the fourth sound-generating module 1500HL, the fifth sound-generating module 1500HR, and the sixth sound-generating module 1500HC can generate sound on the upper side of the display panel 110, thereby improving sound from the upper side of the display panel 110. For example, the seventh sound generating module 1500BL, the eighth sound generating module 1500BR, and the ninth sound generating module 1500BC can generate sound below the display panel 110, thereby improving the sound from below the display panel 110.

[0362] A woofer may be disposed to further improve the sound in the low-frequency range. For example, at least one woofer may be disposed below at least one of the seventh region 7 and the eighth region 8. For example, at least one woofer may be disposed below at least one of the seventh sound-generating module 1500BL and the eighth sound-generating module 1500BR. For example, the first woofer W3 may be disposed below (or below) the seventh region 7 of the display panel 110. For example, the first woofer W3 may be disposed below (or below) the seventh sound-generating module 1500BL. For example, the second woofer W4 may be disposed below (or below) the eighth region 8 of the display panel 110. For example, the second woofer W4 may be disposed below (or below) the eighth sound-generating module 1500BR. Therefore, the first woofer W3 and the second woofer W4 can output sound in the low-frequency range.

[0363] As another example, at least one of the seventh sound-generating module 1500BL and the eighth sound-generating module 1500BR may be configured as a sound-generating module including a woofer, without configuring the first woofer (W3) and the second woofer (W4). For example, the seventh region 7 may be configured with a first woofer-integrated sound-generating module (W1) and the eighth region 8 may be configured with a second woofer-integrated sound-generating module (W2). For example, a sound-generating module including a woofer may be configured in one or more of the seventh region 7 and the eighth region 8. The first woofer-integrated sound-generating module (W1) and the second woofer-integrated sound-generating module (W2) are the same as those described in Figures 24A to 25B, so their description will be omitted here.

[0364] When the first woofer-integrated sound-generating module (W1) is disposed in the seventh region 7, the first woofer-integrated sound-generating module (W1) may be disposed symmetrically with either the first sound-generating module 1500L or the fourth sound-generating module 1500HL. For example, the first woofer-integrated sound-generating module (W1) may be aligned in the same line as either the first sound-generating module 1500L or the fourth sound-generating module 1500HL. When the second woofer-integrated sound-generating module (W2) is disposed in the eighth region 8, the second woofer-integrated sound-generating module (W2) may be disposed in the same line as either the second sound-generating module 1500R or the fifth sound-generating module 1500HR. For example, the second woofer-integrated sound-generating module (W2) may be aligned in the same line as either the second sound-generating module 1500R or the fifth sound-generating module 1500HR. In this configuration, the sound reproduction positions can be aligned on the same line, giving the effect of sounds being reproduced from the same position, which can improve the perception of the sound position and improve the sense of sound localization.

[0365] As another example, when the first woofer-integrated sound-generating module (W1) is arranged in the seventh region 7, the first woofer-integrated sound-generating module (W1) may be arranged asymmetrically with either the first sound-generating module 1500L or the fourth sound-generating module 1500HL. For example, the first woofer-integrated sound-generating module (W1) may be arranged on a different line from either the first sound-generating module 1500L or the fourth sound-generating module 1500HL. When the second woofer-integrated sound-generating module (W2) is arranged in the eighth region 8, the second woofer-integrated sound-generating module (W2) may be arranged asymmetrically with either the second sound-generating module 1500R or the fifth sound-generating module 1500HR. For example, the second woofer-integrated sound-generating module (W2) may be arranged on a different line from either the second sound-generating module 1500R or the fifth sound-generating module 1500HR. For example, the first woofer-integrated sound-generating module (W1) and the second woofer-integrated sound-generating module (W2) can be arranged on a different line from the third sound-generating module 1500C, but this is not limiting. This configuration can reduce acoustic reinforcement or cancellation due to vibration interference between the vibrations and standing waves generated by the first woofer-integrated sound-generating module (W1) and the vibrations and standing waves generated by the fourth sound-generating module 1500HL or the seventh sound-generating module 1500BL. Unwanted acoustic reinforcement or cancellation interference due to external interference, as well as vibrations from the sound source being reproduced, can cause sound distortion and degradation of sound quality. However, the asymmetric structure of either the fourth sound-generating module 1500HL or the seventh sound-generating module 1500BL and the first woofer-integrated sound-generating module (W1) can prevent this, allowing for the reproduction of natural sound that is closer to the original sound. It is possible to reduce acoustic reinforcement or cancellation due to vibration interference between the vibrations and standing waves generated by the second woofer-integrated sound generating module (W2) and the vibrations and standing waves generated by the fifth sound generating module 1500HR or the eighth sound generating module 1500BR.In addition to vibrations caused by the sound source being reproduced, unnecessary acoustic reinforcement or cancelling interference due to external interference can cause sound distortion and deterioration in sound quality. However, the asymmetric structure of either the fifth sound generating module 1500HR or the eighth sound generating module 1500BR and the second woofer-integrated sound generating module value (W2) can prevent this and reproduce natural sound that is close to the original sound.

[0366] As another example, at least one of the first sound-generating module 1500L and the second sound-generating module 1500R may be configured as a sound-generating module including a woofer, without configuring the first woofer (W3) and the second woofer (W4). For example, the first woofer-integrated sound-generating module (W1) may be configured in the first region 1, and the second woofer-integrated sound-generating module (W2) may be configured in the second region 2. For example, a sound-generating module including a woofer may be configured in one or more of the first region 1 and the second region 2. The first woofer-integrated sound-generating module (W1) and the second woofer-integrated sound-generating module (W2) are the same as those described in Figures 24A to 25B, so their description will be omitted here. The description will be the same as that for arranging the first woofer-integrated sound-generating module (W1) and the second woofer-integrated sound-generating module (W2) in the seventh region 7 and the eighth region 8, so their description will be omitted here.

[0367] As another example, at least one of the tenth sound-generating module 1500LC and the eleventh sound-generating module 1500RC may be configured as a sound-generating module including a woofer, without configuring the first woofer (W3) and the second woofer (W4). For example, the tenth region 10 may be configured with a first woofer-integrated sound-generating module (W1) and the eleventh region 11 may be configured with a second woofer-integrated sound-generating module (W2). For example, one or more of the tenth region 10 and the eleventh region 11 may be configured with a sound-generating module including a woofer.

[0368] As another example, at least one of the fourth sound-generating module 1500HL and the fifth sound-generating module 1500HR may be configured as a sound-generating module including a woofer, without configuring the first woofer (W3) and the second woofer (W4). For example, a first woofer-integrated sound-generating module (W1) may be configured in the fourth region 4, and a second woofer-integrated sound-generating module (W2) may be configured in the fifth region 5. For example, a sound-generating module including a woofer may be configured in one or more of the fourth region 4 and the fifth region 5.

[0369] As another example, at least one of the sixth sound-generating module 1500HC and the ninth sound-generating module 1500BC may be configured as a sound-generating module including a woofer, without configuring the first woofer (W3) and the second woofer (W4). For example, the sixth region 6 may be configured with a first woofer-integrated sound-generating module (W1) and the ninth region 9 may be configured with a second woofer-integrated sound-generating module (W2). For example, one or more of the sixth region 6 and the ninth region 9 may be configured with a sound-generating module including a woofer. As another example, the third region 3 may be configured with a sound-generating module including a woofer. For example, the third sound-generating module 1500C may be configured with a sound-generating module including a woofer.

[0370] Therefore, without configuring a woofer separately, it is possible to provide a display device that can output low-, mid-, and high-frequency sounds by disposing the woofer-integrated sound-generating module in at least one of the first area 1 to the eleventh area 11 and outputting low-frequency sounds. When configured in this manner, the sound-generating modules can be driven by applying the same signal or a monaural signal.

[0371] The first sound-generating module 1500L, the second sound-generating module 1500R, the third sound-generating module 1500C, the fourth sound-generating module 1500HL, the fifth sound-generating module 1500HR, the sixth sound-generating module 1500HC, the seventh sound-generating module 1500BL, the eighth sound-generating module 1500BR, the ninth sound-generating module 1500BC, the tenth sound-generating module 1500LC, and the eleventh sound-generating module 1500RC can output sound in the range of 80 Hz to 40 kHz. The first woofer (W3) and the second woofer (W4) can output sound below 80 Hz. Therefore, the display device can output 11.1-channel sound.

[0372] A display device according to an embodiment of the present specification can realize left-right and up-down sounds for left-right and up-down images and can realize real stereophonic sound (e.g., real sound) including stereophonic left-right and up-down sounds to a user, thereby providing real sound rather than virtual sound. This allows the user to realize real stereophonic sound or surround sound (e.g., real sound) including stereophonic left-right and up-down sounds, thereby enhancing the sense of realism. Therefore, even in devices such as movie theaters, private cinemas, and televisions, users can experience real sound and images at the same time in a manner similar to or identical to reality, for example, they can experience a realistic AV (AudioVisual) or Dolby sound system.

[0373] Furthermore, when the sound generating module having the multi-channels of FIGS. 24A and 24B is implemented on the sound plate of FIGS. 23A to 23D, it is possible to realize a real stereophonic sound or surround sound that is an actual sound (e.g., real sound) including stereophonic left and right sounds and stereophonic sounds above and below, thereby improving the sense of realism. When the sound generating module having the multi-channels of FIGS. 24A and 24B is implemented on the sound plate of FIGS. 23A to 23D and a projector or video playback device are respectively configured, it is possible to provide a realistic AV (Audio Visual) or Dolby sound system, for example, so that the user can experience real sound and video simultaneously in a manner similar to or identical to reality, thereby providing immersive and realistic stereophonic sound. Furthermore, as described with reference to FIGS. 1 to 22, the application of a modularized sound generating module can improve the design freedom of the display device or rear cover when arranging the sound generating module.

[0374] FIG. 28 is a diagram showing a display device including a sound generating module according to another embodiment of the present specification.

[0375] Referring to FIG. 28, the display panel 110 may include a first region 1 to a fifteenth region 15. The first region 1 to the fifteenth region 15 may have the same area, but is not limited to this. For example, the first region 1 to the fifteenth region 15 may be arranged at equal intervals, but is not limited to this. For example, the first region 1, the fourth region 4, and the seventh region 7 may be regions on the left side of the rear surface of the display panel 110. For example, the second region 2, the fifth region 5, and the eighth region 8 may be regions on the right side of the rear surface of the display panel 110. For example, the third region 3, the sixth region 6, and the ninth region 9 may be central regions on the rear surface of the display panel 110. For example, the twelfth region 12 may be a region between the fourth region 4 and the sixth region 6. For example, the thirteenth region 13 may be a region between the fifth region 5 and the sixth region 6. For example, the fourteenth region 14 may be a region between the seventh region 7 and the ninth region 9. For example, the 15th region 15 may be a region between the 8th region 8 and the 9th region 9. For example, the 10th region 10, the 12th region 12, and the 14th region 14 may be regions between the 1st region 1, the 4th region 4, and the 7th region 7 and the 3rd region 3, the 6th region 6, and the 9th region 9. For example, the 11th region 11, the 13th region 13, and the 15th region 15 may be regions between the 2nd region 2, the 5th region 5, and the 8th region 8 and the 3rd region 3, the 6th region 6, and the 9th region 9. The numbers 1 to 15 indicating the regions in the 1st region 1 to the 15th region 15 are arbitrary, and the division of the numbers 1 to 15 and the 1st region to the 15th region does not limit the contents of the specification. The same or similar explanation can be applied to Figures 29 to 44C.

[0376] At least one sound-generating module may be arranged in at least one of the first region 1 to the fifteenth region 15. For example, the first sound-generating module 1500L may be arranged in the first region 1 on the rear surface of the display panel 110, the fourth sound-generating module 1500HL may be arranged in the fourth region 4 on the rear surface of the display panel 110, and the seventh sound-generating module 1500BL may be arranged in the seventh region 7 on the rear surface of the display panel 110. The second sound-generating module 1500R may be arranged in the second region 2 on the rear surface of the display panel 110, the fifth sound-generating module 1500HR may be arranged in the fifth region 5 on the rear surface of the display panel 110, and the eighth sound-generating module 1500BR may be arranged in the eighth region 8 on the rear surface of the display panel 110. The third sound-generating module 1500C may be disposed in a third region 3 on the back surface of the display panel 110, the sixth sound-generating module 1500HC may be disposed in a sixth region 6 on the back surface of the display panel 110, and the ninth sound-generating module 1500BC may be disposed in a ninth region 9 on the back surface of the display panel 110. The tenth sound-generating module 1500LC may be disposed in a tenth region 10 on the back surface of the display panel 110, the twelfth sound-generating module 1500HLC may be disposed in a twelfth region 12 on the back surface of the display panel 110, and the fourteenth sound-generating module 1500BLC may be disposed in a fourteenth region 14 on the back surface of the display panel 110. The eleventh sound-generating module 1500RC can be arranged in an eleventh region 11 on the back surface of the display panel 110, the thirteenth sound-generating module 1500HRC can be arranged in a thirteenth region 13 on the back surface of the display panel 110, and the fifteenth sound-generating module 1500BRC can be arranged in a fifteenth region 15 on the back surface of the display panel 110. As another example, the first to fifteenth sound-generating modules can be arranged on the back surface of the rear cover as described in FIG. 22. The first to fifteenth sound-generating modules can be arranged in a modular structure.

[0377] The first sound-generating module 1500L may be the left channel of the display panel 110, the fourth sound-generating module 1500HL may be the height left channel of the display panel 110, and the seventh sound-generating module 1500BL may be the bottom left channel of the display panel 110. The tenth sound-generating module 1500LC may be the left center channel of the display panel 110, the twelfth sound-generating module 1500HLC may be the height left center channel of the display panel 110, and the fourteenth sound-generating module 1500BLC may be the bottom left center channel of the display panel 110. The second sound-generating module 1500R may be the right channel of the display panel 110, the fifth sound-generating module 1500HR may be the height right channel of the display panel 110, and the eighth sound-generating module 1500BR may be the bottom right channel of the display panel 110. The eleventh sound-generating module 1500RC may be the right center channel of the display panel 110, the thirteenth sound-generating module 1500HRC may be the height right center channel of the display panel 110, and the fifteenth sound-generating module 1500BRC may be the bottom right center channel of the display panel 110. The third sound generating module 1500C may be the center channel of the display panel 110, the sixth sound generating module 1500HC may be the height center channel of the display panel 110, and the ninth sound generating module 1500BC may be the bottom center channel of the display panel 110.

[0378] For example, but not limited to, the first sound-generating module 1500L can be arranged symmetrically with the fourth sound-generating module 1500HL and / or the seventh sound-generating module 1500BL. For example, but not limited to, the first sound-generating module 1500L can be aligned collinearly with the fourth sound-generating module 1500HL and / or the seventh sound-generating module 1500BL. For example, but not limited to, the second sound-generating module 1500R can be arranged symmetrically with the fifth sound-generating module 1500HR and / or the eighth sound-generating module 1500BR. For example, but not limited to, the second sound-generating module 1500R can be aligned collinearly with the fifth sound-generating module 1500HR and / or the eighth sound-generating module 1500BR. For example, but not limited to, the third sound-generating module 1500C can be arranged symmetrically with the sixth sound-generating module 1500HC and / or the ninth sound-generating module 1500BC. For example, the third sound-generating module 1500C may be aligned on the same line as the sixth sound-generating module 1500HC and / or the ninth sound-generating module 1500BC, but this is not limiting. In this configuration, the sound reproduction positions may be aligned on the same line, creating the effect of sounds being reproduced from the same position. This may improve the perception of the sound position, thereby improving the sense of sound localization.

[0379] For example, but not limited to, the tenth sound-generating module 1500LC can be arranged symmetrically with either the twelfth sound-generating module 1500HLC and / or the fourteenth sound-generating module 1500BLC. For example, but not limited to, the tenth sound-generating module 1500LC can be aligned in the same line with either the twelfth sound-generating module 1500HLC and / or the fourteenth sound-generating module 1500BLC. For example, but not limited to, the eleventh sound-generating module 1500RC can be arranged symmetrically with either the thirteenth sound-generating module 1500HRC and / or the fifteenth sound-generating module 1500BRC. For example, but not limited to, the eleventh sound-generating module 1500RC can be aligned in the same line with either the thirteenth sound-generating module 1500HRC and / or the fifteenth sound-generating module 1500BRC. In this configuration, the sound reproduction positions can be aligned in the same line, creating the effect of sounds being reproduced from the same position. This can improve the perception of the location of the sound, thereby improving the sense of sound localization.

[0380] For example, but not limited to, one of the fourth sound-generating module 1500HL, the fifth sound-generating module 1500HR, and the sixth sound-generating module 1500HC can be arranged symmetrically with either the twelfth sound-generating module 1500HLC or the thirteenth sound-generating module 1500HRC. For example, but not limited to, one of the fourth sound-generating module 1500HL, the fifth sound-generating module 1500HR, and the sixth sound-generating module 1500HC can be aligned on the same line as either the twelfth sound-generating module 1500HLC or the thirteenth sound-generating module 1500HRC. For example, but not limited to, one of the first sound-generating module 1500L, the second sound-generating module 1500R, and the third sound-generating module 1500C can be arranged symmetrically with either the tenth sound-generating module 1500LC or the eleventh sound-generating module 1500RC. For example, but not limited to, one of the first sound-generating module 1500L, the second sound-generating module 1500R, and the third sound-generating module 1500C can be aligned in the same line as either the tenth sound-generating module 1500LC or the eleventh sound-generating module 1500RC. For example, but not limited to, one of the seventh sound-generating module 1500BL, the eighth sound-generating module 1500BR, and the ninth sound-generating module 1500BC can be arranged symmetrically with either the fourteenth sound-generating module 1500BLC or the fifteenth sound-generating module 1500BRC. For example, but not limited to, one of the seventh sound-generating module 1500BL, the eighth sound-generating module 1500BR, and the ninth sound-generating module 1500BC can be aligned in the same line as either the fourteenth sound-generating module 1500BLC or the fifteenth sound-generating module 1500BRC. In this configuration, the sound reproduction positions can be aligned on the same line, giving the effect of sounds being reproduced from the same position, which can improve the perception of the sound position and improve the sense of sound localization.

[0381] A woofer may be disposed to further improve the sound in the low-frequency range. For example, a woofer may be disposed below at least one of the first region 1 to the fifteenth region 15. For example, a woofer may be further disposed below at least one of the first sound-generating modules 1500L to 15th sound-generating modules 1500BRC. For example, the first woofer (W3) may be disposed below (or below) the seventh region 7 of the display panel 110. For example, the second woofer (W4) may be disposed below (or below) the seventh sound-generating module 1500BL. For example, the first woofer (W3) may be disposed between the seventh region 7 and the fourteenth region 14. For example, the second woofer (W4) may be disposed below (or below) the eighth region 8 of the display panel 110. For example, the second woofer (W4) may be disposed below (or below) the eighth sound-generating module 1500BR. For example, the second woofer (W4) may be disposed between the eighth region (8) and the fifteenth region 15. Therefore, the first woofer (W1) and the second woofer (W2) can output sounds in the low frequency range.

[0382] As another example, at least one of the seventh sound-generating module 1500BL and the eighth sound-generating module 1500BR may be configured as a sound-generating module including a woofer, without configuring the first woofer (W3) and the second woofer (W4). For example, the seventh region 7 may be configured with a first woofer-integrated sound-generating module (W1) and the eighth region 8 may be configured with a second woofer-integrated sound-generating module (W2). For example, a sound-generating module including a woofer may be configured in one or more of the seventh region 7 and the eighth region 8. The first woofer-integrated sound-generating module (W1) and the second woofer-integrated sound-generating module (W2) are the same as those described in Figures 24A to 25B, so their description will be omitted here.

[0383] When the first woofer-integrated sound-generating module (W1) is disposed in the seventh region 7, the first woofer-integrated sound-generating module (W1) may be disposed symmetrically with either the first sound-generating module 1500L or the fourth sound-generating module 1500HL. For example, the first woofer-integrated sound-generating module (W1) may be aligned in the same line as either the first sound-generating module 1500L or the fourth sound-generating module 1500HL. When the second woofer-integrated sound-generating module (W2) is disposed in the eighth region 8, the second woofer-integrated sound-generating module (W2) may be disposed in the same line as either the second sound-generating module 1500R or the fifth sound-generating module 1500HR. For example, the second woofer-integrated sound-generating module (W2) may be aligned in the same line as either the second sound-generating module 1500R or the fifth sound-generating module 1500HR. In this configuration, the sound reproduction positions can be aligned on the same line, giving the effect of sounds being reproduced from the same position, which can improve the perception of the sound position and improve the sense of sound localization.

[0384] As another example, when the first woofer-integrated sound-generating module (W1) is arranged in the seventh region 7, the first woofer-integrated sound-generating module (W1) may be arranged asymmetrically with either the first sound-generating module 1500L or the fourth sound-generating module 1500HL. For example, the first woofer-integrated sound-generating module (W1) may be arranged on a line different from either the first sound-generating module 1500L or the fourth sound-generating module 1500HL. When the second woofer-integrated sound-generating module (W2) is arranged in the eighth region 8, the second woofer-integrated sound-generating module (W2) may be arranged asymmetrically with either the second sound-generating module 1500R or the fifth sound-generating module 1500HR. For example, the second woofer-integrated sound-generating module (W2) may be arranged on a line different from either the second sound-generating module 1500R or the fifth sound-generating module 1500HR. For example, the first woofer-integrated sound-generating module (W1) and the second woofer-integrated sound-generating module (W2) can be arranged on a different line from the third sound-generating module 1500C, but this is not limiting. This configuration can reduce acoustic reinforcement or cancellation due to vibration interference between the vibrations and standing waves generated by the first woofer-integrated sound-generating module (W1) and the vibrations and standing waves generated by the fourth sound-generating module 1500HL or the seventh sound-generating module 1500BL. Unwanted acoustic reinforcement or cancellation due to external interference, as well as vibrations from the sound source being reproduced, can cause sound distortion and degradation of sound quality. However, the asymmetric structure of either the fourth sound-generating module 1500HL or the seventh sound-generating module 1500BL and the first woofer-integrated sound-generating module (W1) can prevent this, allowing for the reproduction of natural sound that is closer to the original sound. It is possible to reduce acoustic reinforcement or cancellation due to vibration interference between the vibrations and standing waves generated by the second woofer-integrated sound generating module (W2) and the vibrations and standing waves generated by the fifth sound generating module 1500HR or the eighth sound generating module 1500BR.In addition to vibrations caused by the sound source being reproduced, unnecessary acoustic reinforcement or cancelling interference due to external interference can cause sound distortion and deterioration in sound quality. However, the asymmetric structure of either the fifth sound generating module 1500HR or the eighth sound generating module 1500BR and the second woofer-integrated sound generating module value (W2) can prevent this and reproduce natural sound that is close to the original sound.

[0385] As another example, at least one of the first sound-generating module 1500L and the second sound-generating module 1500R may be configured as a sound-generating module including a woofer, without configuring the first woofer (W3) and the second woofer (W4). For example, the first woofer-integrated sound-generating module (W1) may be configured in the first region 1, and the second woofer-integrated sound-generating module (W2) may be configured in the second region 2. For example, a sound-generating module including a woofer may be configured in one or more of the first region 1 and the second region 2. The first woofer-integrated sound-generating module (W1) and the second woofer-integrated sound-generating module (W2) are the same as those described in FIGS. 24A to 25B, so their description will be omitted here. The description will be the same as that for the first woofer-integrated sound-generating module (W1) and the second woofer-integrated sound-generating module (W2) arranged in the first region 1 and the second region 2, so their description will be omitted here.

[0386] As another example, at least one of the tenth sound-generating module 1500LC and the eleventh sound-generating module 1500RC may be configured as a sound-generating module including a woofer, without configuring the first woofer (W3) and the second woofer (W4). For example, the tenth region 10 may be configured with the first woofer-integrated sound-generating module (W1) and the eleventh region 11 may be configured with the second woofer-integrated sound-generating module (W2). For example, a sound-generating module including a woofer may be configured in one or more of the tenth region 10 and the eleventh region 11. The first woofer-integrated sound-generating module (W1) and the second woofer-integrated sound-generating module (W2) are the same as those described in FIGS. 24A to 25B, so a description thereof will be omitted here. The description thereof will be the same as that for the first woofer-integrated sound-generating module (W1) and the second woofer-integrated sound-generating module (W2) arranged in the tenth region 10 and the eleventh region 11, so a description thereof will be omitted here.

[0387] As another example, at least one of the fourteenth sound-generating module 1500BLC and the fifteenth sound-generating module 1500BRC may be configured as a sound-generating module including a woofer, without configuring the first woofer (W3) and the second woofer (W4). For example, the fourteenth region 14 may be configured with a first woofer-integrated sound-generating module (W1) and the fifteenth region 15 may be configured with a second woofer-integrated sound-generating module (W2). For example, a sound-generating module including a woofer may be configured in one or more of the fourteenth region 14 and the fifteenth region 15. The first woofer-integrated sound-generating module (W1) and the second woofer-integrated sound-generating module (W2) are the same as those described in Figures 24A to 25B, so their description will be omitted here. The explanation for this is the same as that for the first woofer-integrated sound-generating module W1 and the second woofer-integrated sound-generating module W2 arranged in the fourteenth area 14 and the fifteenth area 15, so the explanation will be omitted here.

[0388] As another example, at least one of the fourth sound-generating module 1500HL and the fifth sound-generating module 1500HR may be configured as a sound-generating module including a woofer, without configuring the first woofer (W3) and the second woofer (W4). For example, a first woofer-integrated sound-generating module (W1) may be configured in the fourth region 4, and a second woofer-integrated sound-generating module (W2) may be configured in the fifth region 5. For example, a sound-generating module including a woofer may be configured in one or more of the fourth region 4 and the fifth region 5.

[0389] As another example, at least one of the twelfth sound-generating module 1500HLC and the thirteenth sound-generating module 1500HRC may be configured as a sound-generating module including a woofer, without configuring the first woofer (W3) and the second woofer (W4). For example, the twelfth region 12 may be configured with a first woofer-integrated sound-generating module (W1) and the thirteenth region 13 may be configured with a second woofer-integrated sound-generating module (W2). For example, one or more of the twelfth region 12 and the thirteenth region 13 may be configured with a sound-generating module including a woofer.

[0390] As another example, at least one of the sixth sound-generating module 1500HC and the ninth sound-generating module 1500BC may be configured as a sound-generating module including a woofer, without configuring the first woofer (W3) and the second woofer (W4). For example, the sixth region 6 may be configured with a first woofer-integrated sound-generating module (W1) and the ninth region 9 may be configured with a second woofer-integrated sound-generating module (W2). For example, one or more of the sixth region 6 and the ninth region 9 may be configured with a sound-generating module including a woofer. As another example, the third region 3 may be configured with a sound-generating module including a woofer. For example, the third sound-generating module 1500C may be configured with a sound-generating module including a woofer.

[0391] Therefore, without configuring a separate woofer, it is possible to provide a display device that can output low-, mid-, and high-frequency sounds by arranging the woofer-integrated sound-generating module in at least one of the first area 1 to the fifteenth area 15 and outputting low-frequency sounds. When configured in this manner, the sound-generating modules can be driven by applying the same signal or a monaural signal.

[0392] Therefore, the first sound-generating module 1500L, the second sound-generating module 1500R, the third sound-generating module 1500C, the fourth sound-generating module 1500HL, the fifth sound-generating module 1500HR, the sixth sound-generating module 1500HC, the seventh sound-generating module 1500BL, the eighth sound-generating module 1500BR, the ninth sound-generating module 1500BC, the tenth sound-generating module 1500LC, the eleventh sound-generating module 1500RC, the twelfth sound-generating module 1500HLC, the thirteenth sound-generating module 1500HRC, the fourteenth sound-generating module 1500BLC, and the fifteenth sound-generating module 1500BRC can output sound in the range of 80 Hz to 40 kHz. The first woofer (W3) and the second woofer (W4) can output sound below 80 Hz. Therefore, the display device can output 15.1-channel sound.

[0393] A display device according to an embodiment of the present specification can realize left-right and up-down sounds for left-right and up-down images and can realize real stereophonic sound (e.g., real sound) including stereophonic left-right and up-down sounds to a user, thereby providing real sound rather than virtual sound. This allows the user to realize real stereophonic sound or surround sound (e.g., real sound) including stereophonic left-right and up-down sounds, thereby enhancing the sense of realism. Therefore, even in devices such as movie theaters, private cinemas, and televisions, users can experience real sound and images at the same time in a manner similar to or identical to reality, for example, they can experience a realistic AV (AudioVisual) or Dolby sound system.

[0394] Furthermore, when the sound generating module having the multi-channels of FIGS. 24A and 24B is implemented on the sound plate of FIGS. 23A to 23D, it is possible to realize a real stereophonic sound or surround sound that is an actual sound (e.g., real sound) including stereophonic left and right sounds and stereophonic sounds above and below, thereby improving the sense of realism. When the sound generating module having the multi-channels of FIGS. 24A and 24B is implemented on the sound plate of FIGS. 23A to 23D and a projector or video playback device are respectively configured, it is possible to provide a realistic AV (AudioVisual) or Dolby sound system, for example, so that the user can experience real sound and video simultaneously in a manner similar to or identical to reality, thereby providing immersive and realistic stereophonic sound. Furthermore, as described with reference to FIGS. 1 to 22, the application of a modularized sound generating module increases the design freedom for the display device or rear cover when arranging the sound generating module.

[0395] 29A to 29E are diagrams showing a sound-generating module and a partition according to another embodiment of the present specification.

[0396] 29A to 29E, the display panel 110 may include a first region 1 to a sixth region 6. The first region 1 to the sixth region 6 may have the same area, but are not limited thereto. For example, the first region 1 to the sixth region 6 may be arranged at the same interval or distance. With this configuration, all channels of the sound generating modules arranged in the first region 1 to the sixth region 6 can reproduce or output the same frequency range (or frequency band), thereby achieving even harmony of sound between the channels. This reduces the difference in sound quality between when there is a sound effect (e.g., when the sound field is wide) and when there is no sound effect (e.g., when the sound field is not wide), thereby achieving uniform or consistent sound quality. As another example, the first region 1, the second region 2, and the third region 3 may have larger areas than the fourth region 4, the fifth region 5, and the sixth region 6. With this configuration, the bass range of the left and right stereo sound can be strengthened, thereby improving the sound quality of general sound without sound effects. As another example, the fourth region 4, fifth region 5, and sixth region 6 may have smaller areas than the first region 1, second region 2, and third region 3. This configuration can strengthen the bass range of the channel responsible for the sound effect, so that when playing back a sound with a sound effect, the sound field, which is the space in which the sound is expressed, can be widened, improving the sound effect that expresses the position of the sound. Therefore, the sizes of the first region 1 to the sixth region 6 can be adjusted depending on the desired sound range.

[0397] Referring to FIGS. 29A to 29E, a partition may be provided around the sound-generating module. The partition may be an air gap or space where sound is generated when the display panel 110 is vibrated by the sound-generating module. The air gap or space that generates or provides sound may be referred to as a partition. The partition may separate sounds or channels, and may block or reduce unclear sound generation due to sound interference. The partition may be an enclosure or a baffle, but is not limited to these terms. In the following examples, the partition is disposed on the rear cover, but the examples herein are not limited thereto and may be disposed on the rear of the display panel. To illustrate the sound-generating module and the partition, the partition will be disposed on the rear cover. For example, if the partition is disposed on the rear cover, the impact of the partition on the display panel on the image quality of the display panel can be reduced. If the sound-generating module is disposed on the rear cover as described in FIG. 22, the partition may be disposed on the rear cover.

[0398] 29A , partitions can be arranged to separate left and right sounds output from a sound generating module arranged behind the display panel 110. For example, partitions can be arranged between the display panel 110 corresponding to the first to sixth regions 1 to 6 of the display panel 110 and the rear cover 300. For example, the fourth partition 1701 can be arranged between the first region 1 and the fourth region 4 and the third region 3. For example, the fourth partition 1701 can be arranged between the first region 1 and the fourth region 4 and the third region 3 and the sixth region 6. The fifth partition 1702 can be arranged between the second region 2 and the fifth region 5 and the third region 3. For example, the fifth partition 1702 can be arranged between the second region 2 and the fifth region 5 and the third region 3. The fourth partition 1701 and the fifth partition 1702 can separate the left and right sounds or left and right channels generated by the first woofer-integrated sound generating module (W1) and the fourth sound generating module 1500HL from the second woofer-integrated sound generating module (W2) and the fifth sound generating module 1500HR.

[0399] To achieve stereophonic or spatial sound, the fourth sound-generating module 1500HL and the fifth sound-generating module 1500HR must be further configured to provide partitions to separate the sounds or channels generated by the fourth sound-generating module 1500HL and the fifth sound-generating module 1500HR from the sounds or channels generated by the first woofer-integrated sound-generating module (W1), the second woofer-integrated sound-generating module (W2), and the third sound-generating module 1500C. When the fourth partition 1701 and the fifth partition 1702 are provided, left and right sounds or left and right channels can be separated. To separate the upper sounds or upper channels and achieve independent sounds in each area with the sound-generating modules located in the rear area of ​​the display panel 110, partitions must be provided to generate sounds from each sound-generating module.

[0400] The partition can be configured to separate channels on the upper side of the display panel 110 from channels on the lower side of the display panel 110. For example, the first partition 1721 can separate channels on the upper side of the display panel 110 from channels on the lower side of the display panel 110. For example, the first partition 1721 can separate sounds or channels generated by the fourth sound-generating module 1500HL and the fifth sound-generating module 1500HR arranged on the upper side of the display panel 110 from sounds or channels generated by the first woofer-integrated sound-generating module (W1), the second woofer-integrated sound-generating module (W2), and the third sound-generating module 1500C arranged on the lower side (or below) of the display panel 110. The second partition 1722 can separate a driver unit arranged on the lower side (or below) of the display panel 110 for driving the display panel 110. For example, the second partition 1722 can be disposed below (or under) the first woofer-integrated sound-generating module (W1), the second woofer-integrated sound-generating module (W2), and the third sound-generating module 1500C. For example, the second partition 1722 can separate the first woofer-integrated sound-generating module (W1), the second woofer-integrated sound-generating module (W2), and the third sound-generating module 1500C from a driver for driving the display panel 110.

[0401] The first partition 1721, the second partition 1722, the fourth partition 1701, and the fifth partition 1702 may be disposed on the rear cover 300. For example, the first partition 1721, the second partition 1722, the fourth partition 1701, and the fifth partition 1702 may be disposed on the front surface of the rear cover 300. For example, the first partition 1721, the second partition 1722, the fourth partition 1701, and the fifth partition 1702 may be disposed between the display panel 110 and the rear cover 300. For example, the first partition 1721, the second partition 1722, the fourth partition 1701, and the fifth partition 1702 may be disposed between the rear surface of the display panel 110 and the front surface of the rear cover 300.

[0402] The first partition 1721, the second partition 1722, the fourth partition 1701, and the fifth partition 1702 may be made of one or more of, but are not limited to, double-sided tape, double-sided foam tape, double-sided foam pad, single-sided tape, single-sided foam tape, single-sided foam pad, adhesive, and bond. When made of double-sided tape or double-sided foam pad, adhesive strength can be improved when attaching the rear surface of the display panel 110 to the front surface of the rear cover 300. For example, the first partition 1721, the second partition 1722, the fourth partition 1701, and the fifth partition 1702 may be made of an elastic material that can be compressed to a certain extent. For example, the first partition 1721, the second partition 1722, the fourth partition 1701, and the fifth partition 1702 may be made of, but are not limited to, polyurethane, polyolefin, and polyethylene.

[0403] Referring to FIG. 29B , a first partition 1721, a fourth partition 1701, and a fifth partition 1702 may be configured, and a partition 1750 may be disposed between the rear cover 300 and the display panel 110. For example, the partition 1750 may be disposed at an edge or periphery of the rear cover 300. For example, the partition 1750 may be disposed at an edge or periphery of the front surface of the rear cover 300. The partition 1750 may cover the entire area of ​​the four sides of the outer periphery of the front surface of the rear cover 300. As another example, the partition 1750 may be disposed at an edge or periphery of the rear surface of the display panel 110. The partition 1750 may cover the entire area of ​​the rear surface of the display panel 110 or the rear cover. For example, the partition 1750 may be disposed to surround the third sound-generating module 1500C, the fourth sound-generating module 1500HL, and the fifth sound-generating module 1500HR. The partition 1750 may be disposed along the shape of the display panel 110 to prevent a wave phenomenon of the display panel 110. The wave phenomenon is a phenomenon in which the shape of the connecting portion, as illustrated in FIG. 4 or 9, becomes noticeable on the screen of the display panel when the thickness of the substrate constituting the display panel is thin, and may cause the display panel or the rear cover to appear uneven or bumpy. For example, if the partition 1750 is an adhesive member for attaching the display panel and the rear cover as illustrated in FIGS. 8, 10, and 19-21, the adhesive member illustrated in FIGS. 8, 10, and 19-21 may be omitted, and the partition 1750 may function as an adhesive member. However, the embodiments of the present specification are not limited thereto, and the adhesive member for attaching the display panel and the rear cover may be configured on the rear surface of the display panel or the rear cover.

[0404] When arranging the first partition 1721, the fourth partition 1701, the fifth partition 1702, and the partition 1750, the first partition 1721 may be arranged, the fourth partition 1701 and the fifth partition 1702 may be arranged, and then the fourth partition 1701 and the fifth partition 1702 may be arranged. As another example, the first partition 1721 may be arranged, the fourth partition 1701 and the fifth partition 1702 may be arranged, and then the partition 1750 may be arranged. However, the order in which the partitions are arranged is not limited to the description of the embodiment of this specification. The partition 1750 may be arranged first in the vertical direction of the rear cover and then in the horizontal direction. As another example, the partition 1750 may be arranged first in the vertical direction of the rear cover and then in the horizontal direction. However, the order in which the partitions are arranged is not limited to the description of the embodiment of this specification. In the following embodiment, an example is shown in which the first partition 1721 is arranged, the partition 1750 is arranged, and then the fourth partition 1701 and the fifth partition 1702 are arranged. However, the embodiment of this specification is not limited to this example. The above explanation can be applied to the following examples in the same or similar manner.

[0405] Referring to FIG. 29C , the shapes of the first partition 1721 and the second partition 1722 can be configured differently. The first partition 1721 and the second partition 1722 can be configured with a shape different from the shape of the display panel 110. For example, the first partition 1721 and the second partition 1722 can be non-flat or non-linear. When the partitions are non-flat or non-linear, standing waves can be dispersed. For example, when the partitions are realized in a sawtooth shape, a triangular shape, and a rounded triangular shape, the sawtooth shape, the triangular shape, and the rounded triangular shape can disperse standing waves in multiple directions, thereby further improving the acoustic output characteristics. For example, the first partition 1721 and the second partition 1722 can have a sawtooth shape, a triangular shape, and a rounded triangular shape. For example, the sawtooth of the partitions can be positioned to face the sound-generating module. For example, if the partitions are triangular, the tips of the triangles can be arranged to face the sound-generating modules. For example, if the partitions are triangular with rounded tips, the tips of the rounded triangles can be arranged to face the sound-generating modules. For example, referring to FIG. 29C , if the first partition 1721 is triangular with rounded tips, the tips of the rounded triangles can be configured to face the fourth sound-generating module 1500HL and the fifth sound-generating module 1500HR. For example, referring to FIG. 29C , if the second partition 1722 is triangular with rounded tips, the tips of the rounded triangles can be configured to face the first woofer-integrated sound-generating module (W1), the second woofer-integrated sound-generating module (W2), and the third sound-generating module 1500C. Therefore, by configuring the shape of the partition to face at least one sound-generating module, it is possible to control the peak and dip phenomena caused by the standing waves of the sound-generating module, and reduce the wave phenomenon of the display panel.By changing the shape of the partition, acoustic interference such as diffuse reflection from the sound generating module can be resolved.

[0406] 29D and 29E, a pad may be further configured on at least one side of the partition. Standing waves, which cause a decrease in sound pressure, may occur frequently at points where the magnitudes of forward and reflected waves are large. Therefore, the pad may be disposed at a position where the sound waves arriving from the sound-generating module are strongest. For example, the pad may be disposed on one or more sides of the partition where the strongest sound waves arrive, and may be configured to face the sound-generating module.

[0407] Referring to FIG. 29D , pads may be arranged on at least one side of the fourth partition 1701 so as to face the first woofer-integrated sound-generating module (W1) and the fourth sound-generating module 1500HL. For example, a 1-3 pad 713 may be arranged on at least one side of the fourth partition 1701 so as to face the first woofer-integrated sound-generating module (W1). A 1-1 pad 711 may be arranged on the side opposite the 1-3 pad 713. The 1-1 pad 711 and the 1-3 pad 713 may each consist of one pad, but this is not limited thereto; one of the 1-1 pad 711 and the 1-3 pad 713 may also consist of two or more pads. For example, a 4-3 pad 723 and a 4-4 pad 724 may be arranged on at least one side of the fourth partition 1701 so as to face the fourth sound-generating module 1500HL. The 4-1 pad 721 and the 4-2 pad 722 may be arranged on the side opposite the 4-3 pad 723 and the 4-4 pad 724. The 4-1 pad 721 to the 4-4 pad 724 may each be composed of two, but this is not limited thereto, and each of the 4-1 pad 721 to the 4-4 pad 724 may be composed of one or three or more. For example, the 3-1 pad 911 may be arranged on at least another side of the fourth partition 1701 so as to face the third sound-generating module 1500C. One or more 3-1 pads 911 may be arranged.

[0408] Pads may be arranged on at least one side of the fifth partition 1702 so as to face the second woofer-integrated sound-generating module (W2) and the fifth sound-generating module 1500HR. For example, a 2-1 pad 811 may be arranged on at least one side of the fifth partition 1702 so as to face the second woofer-integrated sound-generating module (W2). A 2-3 pad 813 may be arranged on the side opposite the 2-1 pad 811. In FIG. 29D, the 2-1 pad 811 and the 2-3 pad 813 may each be formed of one pad. However, this is not limited to this, and one of the 2-1 pad 811 and the 2-3 pad 813 may also be formed of two or more pads. For example, a 5-1 pad 821 and a 5-2 pad 822 may be arranged on at least one side of the fifth partition 1702 so as to face the fifth sound-generating module 1500HR. The 5-3 pad 823 and the 5-4 pad 824 may be arranged on the side opposite the 5-1 pad 821 and the 5-2 pad 822. The 5-1 pads 821 to the 5-4 pads 824 may each be configured with two pads, but this is not limited to this, and the pads may be configured with any one of the 5-1 pads 821 to the 5-4 pads 824 or three or more pads. For example, the 3-3 pad 913 may be arranged on another side of the fifth partition 1702 so as to face the third sound-generating module 1500C. The 3-3 pad 913 may be arranged on the side opposite the 3-1 pad 911. One or more of the 3-1 pad 911 and the 3-3 pad 913 may be arranged.

[0409] Pads may be arranged on at least one side of the first partition 1721 to face the first woofer-integrated sound-generating module (W1), the second woofer-integrated sound-generating module (W2), and the third sound-generating module 1500C. For example, a 1-5 pad 715 may be arranged on at least one side of the first partition 1721 to face the first woofer-integrated sound-generating module (W1). For example, a 2-5 pad 815 may be arranged on at least one side of the first partition 1721 to face the second woofer-integrated sound-generating module (W2). For example, a 3-5 pad 915 may be arranged on at least one side of the first partition 1721 to face the third sound-generating module 1500C. For example, a 4-6 pad 726 may be arranged on at least one side of the first partition 1721 to face the fourth sound-generating module 1500HL. For example, the 5-6 pad 826 may be arranged on at least one side of the first partition 1721 so as to face the fifth sound-generating module 1500HR. For example, the 4-5 pad 725 may be arranged on the side opposite the 4-6 pad 726, and the 4-5 pad 725 may be arranged so as to face the fourth sound-generating module 1500HL. The 5-5 pad 825 may be arranged on the side opposite the 5-6 pad 826, and the 5-5 pad 825 may be arranged so as to face the fifth sound-generating module 1500HR. Each of the 1-5 pad 715, the 2-5 pad 815, the 3-5 pad 915, the 4-5 pad 725, the 4-6 pad 726, the 5-5 pad 825, and the 5-6 pad 826 may be configured as a single pad. As another example, any one of the 1-5 pad 715, the 2-5 pad 815, the 3-5 pad 915, the 4-5 pad 725, the 4-6 pad 726, the 5-5 pad 825, and the 5-6 pad 826 may be configured with two or more.

[0410] For example, the 1-6 pad 716 may be arranged on at least one side of the second partition 1722 so as to face the first woofer-integrated sound-generating module (W1). For example, the 2-6 pad 816 may be arranged on at least one side of the second partition 1722 so as to face the second woofer-integrated sound-generating module (W2). For example, the 3-6 pad 916 may be arranged on at least one side of the second partition 1722 so as to face the third sound-generating module 1500C. For example, the 1-5 pad 715 may be arranged on the side opposite the 1-6 pad 716, and the 1-5 pad 715 may be arranged so as to face the first woofer-integrated sound-generating module (W1). The 2-5 pad 815 may be arranged on the side opposite the 2-6 pad 816, and the 2-5 pad 815 may be arranged so as to face the second woofer-integrated sound-generating module (W2). The 3-5 pad 915 can be arranged on the side opposite the 3-6 pad 916, and the 3-5 pad 915 can be arranged to face the third sound-generating module 1500C. The 1-5 pad 715, the 1-6 pad 716, the 2-5 pad 815, the 2-6 pad 816, the 3-5 pad 915, and the 3-6 pad 916 can be configured as a single pad. As another example, any one of the 1-5 pad 715, the 1-6 pad 716, the 2-5 pad 815, the 2-6 pad 816, the 3-5 pad 915, and the 3-6 pad 916 can be configured as two or more pads.

[0411] In the embodiments of the present specification, the sizes of the 1-1 pad 711 and the 1-3 pad 713 are shown to be larger than the 1-5 pad 715 and the 1-6 pad 716, respectively, but the size of the pads is not a limitation of the present specification. For example, the sizes of the 1-1 pad 711 and the 1-3 pad 713 may be smaller or the same as the 1-5 pad 715 and the 1-6 pad 716, respectively. This can also be applied to other pads. In FIG. 29D, a partition may not be disposed around the periphery of the rear cover 300. The rear cover 300 and the display panel 110 may be attached to each other around the periphery of the rear cover 300 using the adhesive member for attaching the display panel and the rear cover described in FIGS. 8, 10, and 19 to 21, and the adhesive member may be a partition.

[0412] 29E, the first partition 1721 and the second partition 1722 may include at least one vent. The vent may be arranged to reduce the reduction in sound pressure caused by standing waves generated by the interference of reflected and traveling waves. The vent may be formed on one or more sides of the partition where the strongest sound waves arrive, and may be configured to face the sound-generating module.

[0413] The first partition 1721 may include one or more vent portions. For example, the first partition 1721 may include a first vent portion 701 facing the first woofer-integrated sound-generating module (W1) and a second vent portion 702 facing the second woofer-integrated sound-generating module (W2). The first partition 1721 may include a third vent portion 703 facing the third sound-generating module 1500C. The reduction in sound pressure due to standing waves in the fourth sound-generating module 1500HL and the fifth sound-generating module 1500HR can be reduced by the fourth-fifth pad 725 and the fifth-fifth pad 825.

[0414] The second partition 1722 may include one or more vents. For example, the second partition 1722 may include a fourth vent 704 facing the first woofer-integrated sound-generating module (W1) and a fifth vent 705 facing the second woofer-integrated sound-generating module (W2). The second partition 1722 may also include a sixth vent 706 facing the third sound-generating module 1500C. The vents may have a "V"-shaped closed structure at the center of the sound-generating module. Without being limited thereto, the vents may have an open structure at the center of the sound-generating module. Having an open vent at the center of the sound-generating module has the advantage of reducing material costs compared to having a closed structure. Experiments on acoustic characteristics confirmed that there was little or no difference in acoustic characteristics between an open vent at the center of the sound-generating module and a closed vent. Therefore, the first partition 1721 and the second partition 1722 may include one or more vents to reduce the reduction in sound pressure caused by standing waves in the sound generating module.

[0415] 29E , the first partition 1721 and the second partition 1722 may include one or more vents, and the partition 1750 may be positioned accordingly. For example, one or more pads may be included on the edges of the partition 1750. On one edge of the partition 1750, the 4th-5th pad 725 may be positioned facing the fourth sound-generating module 1500HL, and the 5th-5th pad 825 may be positioned facing the fifth sound-generating module 1500HR. Configuring the partition 1750 can improve the fixing force of the sound-generating module positioned behind the display panel and reduce sound leakage from the edge of the display panel, thereby improving the sound output characteristics.

[0416] 30A to 30E are diagrams showing a sound-generating module and a partition according to another embodiment of the present specification.

[0417] 30A and 30B, the contents are the same as or similar to those described in FIGS. 29A and 29B, and therefore will not be described here.

[0418] Referring to FIG. 30C , the first partition 1721 may be composed of, but is not limited to, two partitions. For example, the first partition 1721 may include a 1-1 partition 1721a and a 1-2 partition 1721b and may be configured with a rounded triangular shape. The tip of the triangle or rounded triangular shape of the 1-1 partition 1721a may be configured to face the fourth sound-generating module 1500HL and the fifth sound-generating module 1500HR. The tip of the triangle or rounded triangular shape of the 1-2 partition 1721b may be configured to face the first sound-generating module 1500L, the second sound-generating module 1500R, and the third sound-generating module 1500C. The tip of the triangle or rounded triangular shape of the second partition 1722 may be configured to face the first sound-generating module 1500L, the second sound-generating module 1500R, and the third sound-generating module 1500C. This makes it possible to control peak and dip phenomena caused by standing waves in the sound generating module and reduce wave phenomena in the display panel. The remaining configuration is the same as or similar to that of FIG. 29C, so detailed description will be omitted. The embodiment of FIG. 29C can be similarly applied to the partition of FIG. 30C. The embodiment of FIG. 30C can be similarly applied to the partition of FIG. 29C.

[0419] Referring to FIG. 30D , the partition 1750 may include a first partition 1721, a fourth partition 1701, a fifth partition 1702, and a partition 1750. For example, the partition 1750 may be arranged to surround the first sound-generating module 1500L to the fifth sound-generating module 1500HR. For example, the partition 1750 may include one or more pads on its sides. On one side of the partition 1750, a 4-5 pad 725 may be arranged to face the fourth sound-generating module 1500HL, and a 5-5 pad 825 may be arranged to face the fifth sound-generating module 1500HR. On the other side of the partition 1750, a 1-6 pad 716 may be arranged to face the first sound-generating module 1500L, a 3-6 pad 916 may be arranged to face the third sound-generating module 1500C, and a 2-6 pad 816 may be arranged to face the second sound-generating module 1500R. By configuring the partition 1750, the fixing strength of the sound-generating module disposed behind the display panel can be improved, and sound leakage from the edges of the display panel can be reduced, thereby improving sound output characteristics. In FIG. 29D, a partition may not be disposed around the periphery of the rear cover 300. The rear cover 300 and the display panel 110 can be attached to each other around the periphery of the rear cover 300 using the adhesive material for attaching the display panel and the rear cover described in FIGS. 8, 10, and 19 to 21, and the adhesive material may be a partition. The remaining configuration is the same or similar to that of FIG. 29D, so detailed description will be omitted. The embodiment of FIG. 29D can be similarly applied to the partition of FIG. 30D. The embodiment of FIG. 30D can be similarly applied to the partition of FIG. 29D.

[0420] 30E, the first partition 1721 may include one or more vent portions. For example, the first partition 1721 may include a first vent portion 701 facing the first sound-generating module 1500L and a second vent portion 702 facing the second sound-generating module 1500R. The first partition 1721 may also include a third vent portion 703 facing the third sound-generating module 1500C. The reduction in sound pressure due to standing waves in the fourth sound-generating module 1500HL and the fifth sound-generating module 1500HR can be reduced by the fourth-fifth pad 725 and the fifth-fifth pad 825.

[0421] The second partition 1722 may include one or more vents. For example, the second partition 1722 may include a fourth vent 704 facing the first sound-generating module 1500L and a fifth vent 705 facing the second sound-generating module 1500R. The second partition 1722 may also include a sixth vent 706 facing the third sound-generating module 1500C. The vents may have a "V"-shaped closed structure at the center of the sound-generating module. However, they may also have an open structure. Having an open vent at the center of the sound-generating module has the advantage of reducing material costs compared to having a closed structure. Experiments on acoustic characteristics confirmed that there was little or no difference in acoustic characteristics between an open vent at the center of the sound-generating module and a closed vent. Therefore, by including one or more vent portions in the first partition 1721 and the second partition 1722, it is possible to reduce the phenomenon of sound pressure reduction due to standing waves in the sound-generating module. The remaining configuration is the same as or similar to that of FIG. 29E, so detailed description will be omitted. The embodiment of FIG. 29E can be similarly applied to the partition of FIG. 30E. The embodiment of FIG. 30E can be similarly applied to the partition of FIG. 29E.

[0422] 31A to 31E are diagrams showing a sound-generating module and a partition according to another embodiment of the present specification.

[0423] 31A to 31E, the rear surface of the display panel 110 may include a first region 1 to a fifteenth region 15. The first region 1 to the fifteenth region 15 may have the same area, but is not limited to this. For example, the first region 1 to the fifteenth region 15 may be arranged at equal intervals, but is not limited to this. The sizes of the first region 1 to the fifteenth region 15 may be adjusted depending on the desired sound range. For example, the first region 1, the fourth region 4, and the seventh region 7 may be regions on the left side of the rear surface of the display panel 110. For example, the second region 2, the fifth region 5, and the eighth region 8 may be regions on the right side of the rear surface of the display panel 110. For example, the third region 3, the sixth region 6, and the ninth region 9 may be central regions on the rear surface of the display panel 110. For example, the sixth region 6 may be a region between the fourth region 4 and the fifth region 5. For example, the ninth region 9 may be a region between the seventh region 7 and the eighth region 8. For example, the tenth region 10 may be a region between the first region 1 and the third region 3. For example, the eleventh region 11 may be a region between the second region 2 and the third region 3. For example, the seventh region 7 may be below the first region 1, and the eighth region 8 may be below the second region 2. For example, the tenth region 10, the twelfth region 12, and the fourteenth region 14 may be regions between the first region 1, the fourth region 4, and the seventh region 7 and the third region 3, the sixth region 6, and the ninth region 9. For example, the eleventh region 11, the thirteenth region 13, and the fifteenth region 15 may be regions between the second region 2, the fifth region 5, and the eighth region 8 and the third region 3, the sixth region 6, and the ninth region 9. The numbers 1 to 15 used to indicate the regions in the first to fifteenth regions are arbitrary, and the numbers 1 to 15 and the division of the regions 1 to 15 do not limit the contents of the specification. The explanations therefor can be applied identically or similarly to Figures 31B to 43C.

[0424] Referring to FIG. 31A , partitions may be further configured around the sound-generating modules. For example, partitions may be disposed between the display panel 110 corresponding to the first to eleventh regions 11 of the display panel 110 and the rear cover 300. For example, a fourth partition 1713 may be disposed between the first region 1, the fourth region 4, and the seventh region 7 and the third region 3, the sixth region 6, and the ninth region 9. The fourth partition 1713 may separate the sounds or channels generated by the first sound-generating module 1500L, the fourth sound-generating module 1500HL, and the seventh sound-generating module 1500BL from the sounds or channels generated by the third sound-generating module 1500C, the sixth sound-generating module 1500HC, and the ninth sound-generating module 1500BC. For example, a fifth partition 1714 may be disposed between the second region 2, the fifth region 5, and the eighth region 8 and the third region 3, the sixth region 6, and the ninth region 9. The fifth partition 1714 can separate the sounds or channels generated by the second sound-generating module 1500R, the fifth sound-generating module 1500HR, and the eighth sound-generating module 1500BR from the sounds or channels generated by the third sound-generating module 1500C, the sixth sound-generating module 1500HC, and the ninth sound-generating module 1500BC. Thus, the fourth partition 1713 and the fifth partition 1714 can separate the left and right sounds.

[0425] The first partition 1721 can separate channels above the display panel 110 from channels below the display panel 110. For example, the first partition 1721 can separate sounds or channels generated by the fourth sound-generating module 1500HL and the fifth sound-generating module 1500HR arranged above the display panel 110 from sounds or channels generated by the seventh sound-generating module 1500BL, the eighth sound-generating module 1500BR, and the ninth sound-generating module 1500BC arranged below (or below) the display panel 110.

[0426] To achieve stereophonic or spatial sound, the tenth sound-generating module 1500LC and the eleventh sound-generating module 1500RC must be further configured with partitions to separate the sounds or channels generated by the tenth sound-generating module 1500LC from the sounds or channels generated by the seventh sound-generating module 1500BL, the eighth sound-generating module 1500BR, and the ninth sound-generating module 1500BC. Furthermore, partitions must be configured to separate the sounds or channels generated by the eleventh sound-generating module 1500RC from the sounds or channels generated by the seventh sound-generating module 1500BL, the eighth sound-generating module 1500BR, and the ninth sound-generating module 1500BC. The fourth partition 1713 and the fifth partition 1714 can separate left and right sounds or left and right channels. To achieve stereophonic or spatial sound, the tenth sound-generating module 1500LC and the eleventh sound-generating module 1500RC must be further configured to provide a partition to separate the sound or channel generated by the tenth sound-generating module 1500LC from the sound or channels generated by the first sound-generating module 1500L, the fourth sound-generating module 1500HL, and the seventh sound-generating module 1500BL. Furthermore, a partition must be provided to separate the sound or channel generated by the eleventh sound-generating module 1500RC from the sound or channels generated by the second sound-generating module 1500R, the fifth sound-generating module 1500HR, and the eighth sound-generating module 1500BR. When the first partition 1721 is provided, it is possible to separate upper and lower sounds or upper and lower channels, but it is not possible to separate the upper and lower sounds or upper and lower channels from the center sound or center channel, so a partition must be provided for this purpose. When the fourth partition 1713 and the fifth partition 1714 are placed, it is possible to separate left and right sounds or left and right channels, but it is not possible to separate left and right sounds or left and right channels from the center sound or center channel, so partitions must be configured for this purpose.

[0427] For example, the sixth partition 1711 may be disposed between the first region 1, the fourth region 4, the seventh region 7, and the tenth region 10. For example, the sixth partition 1711 can separate the sounds or channels generated by the first sound-generating module 1500L, the fourth sound-generating module 1500HL, and the seventh sound-generating module 1500BL from the sounds or channels generated by the tenth sound-generating module 1500LC, thereby improving the sound output characteristics. For example, the sixth partition 1711 can separate the sounds or channels generated by the first sound-generating module 1500L, the fourth sound-generating module 1500HL, and the seventh sound-generating module 1500BL from the sounds or channels generated by the third sound-generating module 1500C, the sixth sound-generating module 1500HC, and the ninth sound-generating module 1500BC, thereby improving the sound output characteristics. For example, the sixth partition 1711 can separate the left sound or left channel, the left center sound or left center channel, and the center sound or center channel, thereby improving the sound output characteristics.

[0428] For example, the seventh partition 1712 may be disposed between the second region 2, the fifth region 5, and the eighth region 8 and the eleventh region 11. For example, the seventh partition 1712 can separate the sounds or channels generated by the second sound-generating module 1500R, the fifth sound-generating module 1500HR, and the eighth sound-generating module 1500BR from the sounds or channels generated by the eleventh sound-generating module 1500RC, thereby improving the sound output characteristics. For example, the seventh partition 1712 can separate the sounds or channels generated by the second sound-generating module 1500R, the fifth sound-generating module 1500HR, and the eighth sound-generating module 1500BR from the sounds or channels generated by the third sound-generating module 1500C, the sixth sound-generating module 1500HC, and the ninth sound-generating module 1500BC, thereby improving the sound output characteristics. For example, the seventh partition 1712 may separate the right sound or right channel, the right center sound or right center channel, and the center sound or center channel, thereby improving the sound output characteristics.

[0429] For example, the fourth partition 1713 may be disposed between the third region 3, the sixth region 6, and the ninth region 9 and the tenth region 10. The fourth partition 1713 can separate the sounds or channels generated by the third sound-generating module 1500C, the sixth sound-generating module 1500HC, and the ninth sound-generating module 1500BC from the tenth sound-generating module 1500LC, thereby improving the acoustic output characteristics. For example, the fifth partition 1714 may be disposed between the third region 3, the sixth region 6, and the ninth region 9 and the eleventh region 11. The fifth partition 1714 can separate the sounds or channels generated by the third sound-generating module 1500C, the sixth sound-generating module 1500HC, and the ninth sound-generating module 1500BC from the eleventh sound-generating module 1500RC, thereby improving the acoustic output characteristics. For example, the fourth partition 1713 can separate the sounds or channels in the central region from the sounds or channels in the left central region. For example, the fifth partition 1714 may separate sounds or channels for the center region from sounds or channels for the right-center region.

[0430] The first partition 1721 can separate the channels on the upper side of the display panel 110 from the channels on the lower side of the display panel 110. For example, the first partition 1721 can separate the sounds or channels generated by the fourth sound-generating module 1500HL, the fifth sound-generating module 1500HR, and the sixth sound-generating module 1500HC from the sounds or channels generated by the seventh sound-generating module 1500BL, the second sound-generating module 1500R, the eighth sound-generating module 1500BR, the ninth sound-generating module 1500BC, and the eleventh sound-generating module 1500RC. The first partition 1721 can separate the channels on the upper side of the display panel 110 from the channels in the center of the display panel 110. For example, the first partition 1721 can separate the sounds or channels generated by the fourth sound generating module 1500HL, the fifth sound generating module 1500HR, and the sixth sound generating module 1500HC from the sounds or channels generated by the first sound generating module 1500L, the second sound generating module 1500R, the third sound generating module 1500C, the tenth sound generating module 1500LC, and the eleventh sound generating module 1500RC.

[0431] The second partition 1722 can separate the central channel of the display panel 110 from the channel below the display panel 110. For example, the second partition 1722 can separate the sounds or channels generated by the first sound-generating module 1500L, the second sound-generating module 1500R, the third sound-generating module 1500C, the tenth sound-generating module 1500LC, and the eleventh sound-generating module 1500RC from the sounds or channels generated by the seventh sound-generating module 1500BL, the eighth sound-generating module 1500BR, and the ninth sound-generating module 1500BC. The third partition 1723 can separate the channel below the display panel 110 from the woofer. For example, the third partition 1723 can be disposed below (or below) the seventh sound-generating module 1500BL, the eighth sound-generating module 1500BR, and the ninth sound-generating module 1500BC. For example, the third partition 1723 can separate the sounds or channels generated by the seventh sound-generating module 1500BL, the eighth sound-generating module 1500BR, and the ninth sound-generating module 1500BC from the first woofer (W3) and the second woofer (W4).

[0432] The first partition 1721, the second partition 1722, the third partition 1723, the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, and the seventh partition 1712 may be disposed on the back cover 300. For example, the first partition 1721, the second partition 1722, the third partition 1723, the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, and the seventh partition 1712 may be disposed on the front side of the back cover 300. For example, the first partition 1721, the second partition 1722, the third partition 1723, the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, and the seventh partition 1712 may be disposed between the display panel 110 and the back cover 300. For example, the first partition 1721, the second partition 1722, the third partition 1723, the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, and the seventh partition 1712 may be disposed between the rear surface of the display panel 110 and the front surface of the rear cover 300.

[0433] The first partition 1721, the second partition 1722, the third partition 1723, the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, and the seventh partition 1712 may be formed using any of, but not limited to, double-sided tape, double-sided foam tape, double-sided foam padding, single-sided tape, single-sided foam tape, single-sided foam padding, adhesive, and bond. When the partitions are formed using double-sided tape, double-sided foam tape, or double-sided foam padding, the adhesive strength can be improved when attaching the rear surface of the display panel 110 to the front surface of the rear cover 300. For example, the first partition 1721, the second partition 1722, the third partition 1723, the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, and the seventh partition 1712 may be made of an elastic material that can be compressed to a certain extent. For example, the first partition 1721, the second partition 1722, the third partition 1723, the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, and the seventh partition 1712 may be made of polyurethane, polyolefin, and polyethylene materials, but are not limited to these.

[0434] 31A to 31E, a fourth sound-generating module 1500HL can be configured in the fourth region 4 and a sixth sound-generating module 1500HC can be configured in the sixth region 6, with no sound-generating module configured in the twelfth region 12. This allows vibrations of the fourth sound-generating module 1500HL and the sixth sound-generating module 1500HC to be attenuated or absorbed in the twelfth region 12 of the display panel 110, thereby blocking or reducing transmission of sound in the fourth region 4 to the sixth region 6 and blocking or reducing transmission of sound in the sixth region 6 to the fourth region 4. This reduces deterioration in sound quality due to interference between sounds generated in the fourth region 4 and the sixth region 6, and has the effect of further improving acoustic characteristics in the mid- to high-frequency range. For example, a fifth sound-generating module 1500HR can be configured in the fifth region 5 and a sixth sound-generating module 1500HC can be configured in the sixth region 6, with no sound-generating module configured in the thirteenth region 13. As a result, the vibrations of the fifth sound-generating module 1500HR and the sixth sound-generating module 1500HC are attenuated or absorbed in the thirteenth region 13 of the display panel 110, so that the transmission of sound in the fifth region 5 to the sixth region 6 can be blocked or reduced, and the transmission of sound in the sixth region 6 to the fifth region 5 can be blocked or reduced. Therefore, it is possible to reduce the deterioration in sound quality caused by interference between the sounds generated in the fifth region 5 and the sixth region 6, and it is possible to further improve the acoustic characteristics in the mid- to high-frequency range.

[0435] The seventh sound-generating module 1500BL can be configured in the seventh region 7 and the ninth sound-generating module 1500BC can be configured in the ninth region 9, with no sound-generating module configured in the fourteenth region 14. This allows vibrations of the seventh sound-generating module 1500BL and the ninth sound-generating module 1500BC to be attenuated or absorbed in the fourteenth region 14 of the display panel 110, thereby blocking or reducing transmission of sound from the seventh region 7 to the ninth region 9, and blocking or reducing transmission of sound from the ninth region 9 to the seventh region 7. This reduces deterioration in sound quality due to interference between sounds generated in the seventh region 7 and the ninth region 9, and has the effect of further improving acoustic characteristics in the mid- to high-frequency range. For example, the eighth sound-generating module 1500BR can be configured in the eighth region 8 and the ninth sound-generating module 1500BC in the ninth region 9, with no sound-generating module configured in the fifteenth region 15. As a result, the vibrations of the eighth sound-generating module 1500BR and the ninth sound-generating module 1500BC are attenuated or absorbed in the fifteenth region 15 of the display panel 110, so that the transmission of sound in the eighth region 8 to the ninth region 9 can be blocked or reduced, and the transmission of sound in the ninth region 9 to the eighth region 8 can be blocked or reduced. Therefore, it is possible to reduce the deterioration in sound quality caused by interference between the sounds generated in the eighth region 8 and the ninth region 9, and it is possible to further improve the acoustic characteristics in the mid- to high-frequency range.

[0436] In Fig. 31A, a partition may not be disposed around the periphery of the rear cover 300. The rear cover 300 and the display panel 110 may be attached to each other around the periphery of the rear cover 300 using an adhesive member for attaching the display panel and the rear cover, as described with reference to Figs. 8, 10, and 19 to 21, and the adhesive member may be a partition.
