[0219] Throughout the drawings and detailed description, unless otherwise indicated, the same reference numerals should be understood to refer to the same elements, features and structures. For the sake of clarity, illustration and convenience, the relative sizes and depictions of these elements may be exaggerated. The progress of the processing steps and / or operations described is an example; however, the order of the steps and / or operations is not limited to the order described herein and can be changed as known in the art (except for the steps and / or operations that must occur in a specific order). The same reference numerals always represent the same elements. The selection of the names of the various elements used in the following description is only for the convenience of writing this specification and may therefore be different from the names used in the actual product.

[0220] The shapes, sizes, proportions, angles, and quantities disclosed in the accompanying drawings for describing the embodiments of the present disclosure are merely examples, and therefore, the present disclosure is not limited to the details shown. Like reference numerals denote like elements throughout. In the following description, when it is determined that a detailed description of related known functions or configurations unnecessarily obscures the key points of the present disclosure, the detailed description will be omitted.

[0221] When “including,” “having,” and “comprising” are used in this specification, another part may be added unless “only” is used. Terms in the singular form may include plural forms unless otherwise stated.

[0222] When explaining an element, the element is interpreted as including an error or tolerance range, even if there is no explicit description of such error or tolerance range. When describing a positional relationship, for example, when the positional relationship between two components is described as "on," "above," "below," and "next to," one or more other components may be arranged between the two components, unless a more restrictive term, such as "only" or "directly," is used. When describing a temporal relationship, for example, when a temporal sequence is described as "after," "subsequently," "next," and "before," discontinuities may be included, unless a more restrictive term, such as "just," "immediately," or "directly," is used.

[0223] It should be understood that although the terms "first" and "second" may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element, without departing from the scope of this disclosure.

[0224] When describing the elements of the present disclosure, the terms "first," "second," "A," "B," "(a)," "(b)," etc. may be used. These terms are intended to distinguish the corresponding elements from other elements, and the basis, order, or number of the corresponding elements should not be limited by these terms. Unless otherwise specified, the statement that one element is "connected," "coupled," or "attached" to another element or layer indicates that the element or layer may be not only directly connected or attached to the other element or layer, but also indirectly connected or attached to the other element or layer and that one or more intermediate elements or layers are "disposed" between the elements or layers.

[0225] The term "at least one" should be understood to include any and all combinations of one or more of the associated listed items. For example, "at least one of the first item, the second item, and the third item" means all combinations of items selected from two or more of the first item, the second item, and the third item, as well as the first item, the second item, or the third item.

[0226] In the description of the embodiments, when one structure is described as being located "on or above" or "below or below" another structure, the description should be interpreted as including a case where the structures are in contact with each other and a case where a third structure is provided therebetween. The size and thickness of each element shown in the drawings are given merely for convenience of description, and unless otherwise specified, the embodiments of the present disclosure are not limited thereto.

[0227] As will be fully understood by those skilled in the art, the features of the various embodiments of the present disclosure may be coupled or combined with each other in part or in whole, and may interact and be technically driven in various ways. The embodiments of the present disclosure may be performed independently of each other, or may be performed together in a mutually dependent relationship.

[0228] In the present disclosure, examples of display devices may include narrowly defined display devices including a display panel and a driver for driving the display panel, such as an organic light-emitting display (OLED) module or a liquid crystal module (LCM). In addition, examples of display devices may include complete sets (or complete sets of equipment) or complete electronic devices that are complete products (or final products) including LCMs or OLED modules, such as laptop computers, TVs, computer monitors, components including automotive equipment or other types of equipment for vehicles, or mobile electronic devices such as smartphones or electronic tablets.

[0229] Therefore, in the present disclosure, examples of the display device may include a display device in a narrow sense such as an LCM or OLED module itself, and a complete device which is a final consumer device or application product including the LCM or OLED module.

[0230] In some embodiments, an LCM or OLED module including a display panel and a driver may be referred to as a narrow display device, and an electronic device as a final product including the LCM or OLED module may be referred to as a complete set. For example, a narrow display device may include a display panel such as an LCD or OLED, and a source printed circuit board (PCB) as a controller for driving the display panel. The complete set may also include a complete PCB, which is a complete controller electrically connected to the source PCB to control the complete set as a whole.

[0231] The display panel applied to this embodiment can use all types of display panels that are vibrated by the sound generating device according to this embodiment to output sound, such as liquid crystal display panels, organic light emitting diode (OLED) display panels, and electroluminescent display panels, but is not limited to a specific display panel. In addition, the shape or size of the display panel applied to the display device according to this embodiment is not limited.

[0232] 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 a plurality of pixels respectively arranged in a plurality of pixel areas defined by intersections of the gate lines and the data lines. In addition, the display panel may include: an array substrate including thin film transistors (TFTs) as switching elements for adjusting the light transmittance of each of the plurality of pixels; an upper substrate including a color filter and / or a black matrix; and a liquid crystal layer located between the array substrate and the upper substrate.

[0233] In addition, if the display panel is an organic light-emitting display panel, the display panel may include a plurality of gate lines, a plurality of data lines, and a plurality of pixels respectively arranged in a plurality of pixel areas defined by the intersections of the gate lines and the data lines. In addition, the display panel may include: an array substrate including a TFT as an element for selectively applying a voltage to each pixel; an organic light-emitting device layer located on the array substrate; and an encapsulation substrate provided on the array substrate to cover the organic light-emitting device layer. The encapsulation substrate may protect the TFT and the organic light-emitting device layer from external impacts and may prevent water or oxygen from penetrating into the organic light-emitting device layer. In addition, the layer provided on the array substrate may include an inorganic light-emitting layer (e.g., a nanoscale material layer or quantum dots, etc.). As another example, the layer provided on the array substrate may include a micro light-emitting diode.

[0234] In the present disclosure, a display panel can be used in a vehicle as a user interface module, such as a central control panel in a car. For example, the display panel can be positioned between passengers in the front seats to transmit vibrations from the display panel to the interior of the vehicle. This improves the audio experience in the vehicle compared to a case where speakers are positioned inside the vehicle.

[0235] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. When adding reference numerals to the elements of each drawing, the same reference numerals may represent the same elements even though the same elements are shown in other drawings. In addition, for ease of description, the scale of each element shown in the drawings is different from the actual scale and is therefore not limited to the scale shown in the drawings.

[0236] Figure 1 A display device according to an embodiment of the present disclosure is shown. Figure 2 It is along Figure 1 The cross-sectional view is taken along line II'.

[0237] Reference Figure 1 and Figure 2 , a display device according to an embodiment of the present disclosure may include a display module 100 , a back cover 300 , and at least one sound generating module 500 .

[0238] The display module 100 can vibrate based on the driving of at least one sound generating module 500 to directly output sound PVS (or panel vibration sound) in the front surface direction (or front area) FD while displaying an image. Alternatively, the display module 100 can vibrate based on the driving of at least one sound generating module 500 to directly output sound PVS to the front area FD when no image is displayed. Therefore, the display module 100 according to the present disclosure can display an image and can generate (or output) sound PVS.

[0239] The display module 100 according to an embodiment of the present disclosure may include a display panel 110 that displays an image. For example, the image may include an electronic image or a digital image.

[0240] The display panel 110 can be implemented as any type of display panel, such as an organic light-emitting diode display panel, a liquid crystal display panel, an electroluminescent display panel, a micro-light-emitting diode display panel, and a quantum dot light-emitting display panel. The display panel 110 can vibrate based on the vibration of the sound generating module 500 to output the sound PVS directly to the front area FD. Therefore, the display panel 110 can be a vibration plate or a speaker that directly generates the sound PVS. For example, when the display module 100 generates the sound PVS, the display module 100 can be a vibration plate, a panel speaker, or a flat panel speaker that directly generates the sound PVS.

[0241] According to some embodiments of the present disclosure, the display panel 110 may include a pixel circuit provided on a substrate (or base plate) and a pixel array layer (or display unit) connected to the pixel circuit and including an anode, a cathode, and an organic light-emitting layer. Based on the structure of the pixel array layer, the display panel 110 can display an image in a type such as a top emission type, a bottom emission type, or a dual emission type. For example, the anode may be referred to as a first electrode or a pixel electrode, and the term is not limited thereto. The cathode may be referred to as a second electrode or a common electrode, and the term is not limited thereto.

[0242] In the top emission type, light generated from the pixel array layer may be output to a front region FD in front of a substrate of the display panel 110. In the bottom emission type, light generated from the pixel array layer may be output to the outside through the substrate, thereby displaying an image.

[0243] 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 .

[0244] The functional film 130 may be attached to the display panel 110 using a transparent adhesive member. For example, the transparent adhesive member may include a pressure sensitive adhesive (PSA), an optically clear adhesive (OCA), or an optically clear resin (OCR), but is not limited thereto.

[0245] According to some embodiments, the functional film 130 may include an anti-reflection layer (or anti-reflection film) for preventing reflection of external light to enhance outdoor visibility and contrast with respect to an image displayed by the display panel 110. For example, the anti-reflection layer may include a circular polarization layer (or circular polarization film) that prevents external light reflected by thin film transistors (TFTs) and / or wiring provided on a pixel array layer of the display panel 110 from propagating to the outside.

[0246] According to some embodiments of the present disclosure, the functional film 130 may further include a light path control layer (or light path control film) for controlling the light output path from the pixel array layer of the display panel 110 to the outside. The light path control layer may include a stacked structure in which high-refractive layers and low-refractive layers are alternately stacked, and may change the path of light incident from the pixel array layer to minimize the color shift phenomenon based on the viewing angle, and, for example, the low-refractive layer may be provided on the uppermost layer of the light path control layer.

[0247] 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 touch. The touch electrode unit may be provided between the display panel 110 and the functional film 130, or may be embedded in the display panel 110 based on an in-cell touch type. For example, the touch electrode unit based on the in-cell touch type may include a mutual capacitance touch electrode or a self-capacitance touch electrode.

[0248] The back cover 300 may be disposed on the rear surface of the display module 100. The back cover 300 may support or fix the sound generating module 500.

[0249] According to some embodiments of the present disclosure, the back cover 300 may cover the rear surfaces of the display module 100 and the sound generating module 500. The back cover 300 may be referred to as a support member, a housing, a system cover, a fixing cover, a back cover, a cover bottom, a rear frame, or a chassis, but the term is not limited thereto. In addition, the rear surface of the display module 100 may be referred to as a surface, a first surface, a rear surface, or a lower surface, but the term is not limited thereto.

[0250] According to some embodiments of the present disclosure, the back cover 300 may include a first back cover 310 and a second back cover 350 .

[0251] The first back cover 310 may be provided on the rear surface of the display module 100 and may cover the display module 100 (e.g., the rear surface of the display panel 110). The first back cover 310 may be separated from the rear surface of the display module 100 with a gap space GS therebetween. The first back cover 310 may support or fix the sound generating module 500. The first back cover 310 may protect the rear surface of the display panel 110 from external impact. In addition, the first back cover 310 may function as a heat sink for dissipating heat generated in the display module 100.

[0252] According to some embodiments of the present disclosure, the first back cover 310 may be a plate member that covers the rear surface of the display module 100 (e.g., the entire rear surface of the display panel 110). For example, the edges or corners of the first back cover 310 may have an inclined or curved shape through a chamfering process or a rounded corner process.

[0253] According to some embodiments of the present disclosure, the first back cover 310 according to the embodiment of the present disclosure may include a glass material, a metal material, or a plastic material. For example, the first back cover 310 including a glass material may include one of sapphire glass and Gorilla Glass or a laminated structure (or bonded structure) thereof, but is not limited thereto. For example, the first back cover 310 including a metal material may include one of aluminum (Al), an aluminum alloy, a magnesium alloy, an iron-nickel alloy, and stainless steel, or may include an alloy material or a bonded (or bonded) structure thereof.

[0254] The second back cover 350 may be disposed on the rear surface of the first back cover 310 and may cover the rear surface of the first back cover 310. According to some embodiments of the present disclosure, the second back cover 350 may be a plate member covering the entire rear surface of the first back cover 310. For example, an edge or corner of the second back cover 350 may have an inclined shape or a curved shape through a chamfering process or a rounding process.

[0255] According to some embodiments of the present disclosure, the second back cover 350 may be formed of one of a glass material, a metal material, or a plastic material, or may be formed of a material different from that of the first back cover 310. For example, the second back cover 350 may be formed of a glass material, and the first back cover 310 may be formed of a metal material with good thermal conductivity, such as Al. For example, the appearance design of the display device can be improved based on the second back cover 350 provided on the rear surface and including a glass material, and the rear surface of the display device can use the first back cover 310 including a metal material as a mirror surface.

[0256] According to some embodiments of the present disclosure, the second back cover 350 according to an embodiment of the present disclosure may have a thickness that is the same as or thinner than the thickness of the first back cover 310 within a tolerance range of the manufacturing process. For example, in order to more stably support the sound generating module 500 and reduce the weight of the display device, the first back cover 310 may have a thickness that is thicker than the second back cover 350.

[0257] According to some embodiments of the present disclosure, the first and second rear covers 310 and 350 may be coupled or connected to each other by a cover coupling member 330. For example, the cover coupling member 330 may be an adhesive resin, a double-sided tape, or a double-sided foam pad, and may have elasticity for absorbing impact.

[0258] According to some embodiments of the present disclosure, the cover coupling member 330 may be provided in the entire region between the first back cover 310 and the second back cover 350 .

[0259] According to some embodiments, the cover coupling member 330 may be provided in a mesh structure including an air gap between the first back cover 310 and the second back cover 350. For example, a portion of the air gap between the first back cover 310 and the second back cover 350 may be used as an arrangement area for a signal transmission member or a cable connected to the sound generating module 500.

[0260] The at least one sound generating module 500 may generate the sound PVS using the display module 100 as a vibration plate. For example, the at least one sound generating module 500 may generate the sound PVS using the display panel 110 as a vibration plate.

[0261] The display device according to some embodiments of the present disclosure may include one sound generating module provided at the rear center portion (or central area) of the display module 100. For example, the one sound generating module may vibrate the rear center portion of the display module 100 to generate sound PVS based on the vibration of the display module 100.

[0262] According to another embodiment of the present disclosure, a display device may include a first sound generating module 500-1 and a second sound generating module 500-2. The first sound generating module 500-1 is disposed in a first region (or left region) of the display module 100, and the second sound generating module 500-2 is disposed in a second region (or right region) of the display module 100, relative to the rear center portion of the display module 100. For example, the first sound generating module 500-1 may vibrate the first rear region of the display module 100 to generate sound (PVS) based on the vibration of the first region of the display module 100. The second sound generating module 500-2 may vibrate the second rear region of the display module 100 to generate sound (PVS) based on the vibration of the second region of the display module 100. A display device according to another embodiment of the present disclosure may output two-channel stereo sound based on left-side and right-side sound separation using the first sound generating module 500-1 and the second sound generating module 500-2. For example, the first sound generating module 500-1 may be configured to output left-side sound, and the second sound generating module 500-2 may be configured to output right-side sound.

[0263] According to some embodiments of the present disclosure, at least one sound generating module 500 may be located between the display module 100 and the back cover 300 and may vibrate the display module 100 to generate sound PVS. The rear surface of the at least one sound generating module 500 may be covered by the back cover 300, thereby being hidden and not directly exposed to the outermost rear surface of the display device. Therefore, since the rear surface of the at least one sound generating module 500 is covered by the back cover 300, the display device according to an embodiment of the present disclosure may have a simple back design, wherein a portion or the rear surface of the at least one sound generating module 500 is not exposed or visible to the user's eyes, thereby improving the rear appearance design.

[0264] According to some embodiments of the present disclosure, the at least one sound generating module 500 may be a single structure or a single structure, wherein the module structure 510 provided at the back cover 300 and the vibration device 530 provided at the module structure 510 to vibrate the display module 100 are modularized into one element. For example, the module structure 510 and the vibration device 530 may be manufactured as a finished product type, such as a single structure or a single structure, through a modularization process (or assembly process) instead of an assembly process performed on the display device. Then, the at least one sound generating module 500 may be installed or provided in the gap space GS between the display module 100 and the back cover 300 through a relatively simple component installation (or positioning) process in the assembly process performed on the display device. Therefore, in the display device according to an embodiment of the present disclosure, the assembly performance of the at least one sound generating module 500 can be improved during the module assembly process, thereby improving the production yield rate.

[0265] The at least one sound generating module 500 according to an embodiment of the present disclosure may vibrate the display module 100 directly or indirectly. For example, the at least one sound generating module 500 may be directly connected to the display panel 110 and may directly vibrate the display panel 110. As another example, the at least one sound generating module 500 may indirectly vibrate the display panel 110 by using a vibration transfer member directly connected to the display panel 110. For example, the vibration transfer member may be implemented in the corresponding sound generating module 500 or the display module 100. For example, the vibration transfer member implemented in the at least one sound generating module 500 may be a vibration transfer plate (or vibration transfer sheet) that contacts (or is coupled to) the display module 100. In addition, the vibration transfer member implemented in the display module 100 may be a backlight module provided on the rear surface of the display panel 110, or may be a vibration transfer plate (or heat dissipation plate) coupled to (or attached to) the rear surface of the display panel 110.

[0266] The display apparatus according to an embodiment of the present disclosure may further include a middle frame 700 .

[0267] The middle frame 700 may be disposed between the rear edge of the display module 100 and the front edge of the back cover 300. The middle frame 700 may support the edge (or periphery) of each of the display module 100 and the back cover 300, and may surround the side surfaces of each of the display module 100 and the back cover 300. The middle frame 700 may provide a gap space GS between the display module 100 and the back cover 300. The gap space GS may be referred to as an air gap, a vibration space, or a sound generating module arrangement space, but the term is not limited thereto.

[0268] According to some embodiments of the present disclosure, the middle frame 700 may be connected or coupled to the rear edge (or rear periphery) of the display module 100 via a first adhesive member 7011, and may be connected or coupled to the front edge (or front periphery) of the rear cover 300 via a second adhesive member 7013. The front surface of the rear cover 300 may be referred to as another surface, a second surface, or an upper surface, but the terms are not limited thereto. Furthermore, the middle frame 700 may be referred to as an intermediate case, an intermediate cover, or an intermediate chassis, but the terms are not limited thereto.

[0269] According to some embodiments of the present disclosure, the middle frame 700 may include a metal material or a plastic material. For example, the middle frame 700 may be formed of a metal material to improve the side appearance design of the display device and protect the side surface of the display device.

[0270] The middle frame 700 according to some embodiments of the present disclosure may include a support portion 7110 and a sidewall portion 7130. The support portion 7110 may be a first portion, and the sidewall portion 7130 may be a second portion, but the terminology is not limited thereto.

[0271] The support portion 7110 may be disposed between the rear edge (or rear periphery) of the display module 100 and the front edge (or front periphery) of the back cover 300, thereby providing a gap space GS between the display module 100 and the back cover 300. The front surface of the support portion 7110 may be coupled to the rear edge of the display module 100 via the first adhesive member 7011, and the rear surface of the support portion 7110 may be coupled to the front edge of the back cover 300 via the second adhesive member 7013. The support portion 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 portion 7110 may be adjusted based on the module thickness of the sound generating module 500 between the display module 100 and the back cover 300, the thickness of the first adhesive member 7011, and the thickness of the second adhesive member 7013.

[0272] According to some embodiments of the present disclosure, the support portion 7110 may have a single square (quadrangular) picture frame structure, but is not limited thereto. For example, the support portion 7110 may be located between the rear edge of the display module 100 and the front edge of the rear cover 300 to have a plurality of partition bar shapes.

[0273] The first adhesive member 7011 may be located between the rear edge of the display module 100 and the front surface of the support portion 7110. For example, the first adhesive member 7011 may be an adhesive resin, a double-sided tape, or a double-sided foam pad, but is not limited thereto.

[0274] The second adhesive member 7013 may be located 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 an adhesive resin, a double-sided tape, or a double-sided adhesive foam pad. The second adhesive member 7013 may be formed of a material different from that of the first adhesive member 7011.

[0275] The sidewall portion 7130 can be perpendicularly coupled to the outer surface of the support portion 7110, parallel to the thickness direction Z of the display device. The sidewall portion 7130 can surround the entire outer surface (or outer sidewall) of the display module 100 and the outer surface (or outer sidewall) of the back cover 300, thereby protecting the outer surface of each of the display module 100 and the back cover 300 and improving the design of the side surface of the display device. The middle frame 700 according to some embodiments of the present disclosure can be coupled to each other so that the support portion 7110 and the sidewall portion 7130 form a single body, thereby obtaining a photo frame structure having a "┣"-shaped single-sided structure.

[0276] The display apparatus according to an embodiment of the present disclosure may include an adhesive member instead of the middle frame 700 .

[0277] The adhesive member may be located between the rear edge of the display module 100 and the front edge of the back cover 300, and may provide a gap space GS between the display module 100 and the back cover 300. The adhesive member may have a thickness (or height) corresponding to the total module thickness of the sound generating module 500. For example, the thickness of the adhesive member may be adjusted based on the module thickness of the sound generating module 500 between the display module 100 and the back cover 300. The adhesive member may perform the same function as the supporting portion 7110 of the middle frame 700.

[0278] When the display device includes an adhesive member instead of the middle frame 700, the back cover 300 may include a side wall covering portion that surrounds the outer surface (or outer side wall) of the display module 100, the outer surface (or outer side wall) of the back cover 300, and the outer surface (or outer side wall) of the adhesive member.

[0279] The sidewall covering portion may extend from the end of the second back cover 350 and may be bent vertically to be parallel to the thickness direction Z of the display device. According to some embodiments of the present disclosure, the sidewall covering portion may have a single sidewall structure or a hemming structure. The hemming structure may refer to a structure in which the ends of any component are bent into a curved shape to overlap each other or to be spaced parallel to each other. For example, the sidewall covering portion with a hemming structure may include a first sidewall and a second sidewall, the first sidewall extending from the end of the second back cover 350 and being bent vertically to be parallel to the thickness direction Z of the display device, and the second sidewall extending from the end of the first sidewall and being bent parallel to the first sidewall. The second sidewall may be located between the outer surface of the display module 100 and the first sidewall, and for example, the second sidewall may not be exposed at the outermost surface of the display device and may be covered by the first sidewall, thereby improving the side appearance design of the display device.

[0280] In the display device according to an embodiment of the present disclosure, the display module 100 may further include a heat dissipation member 150 .

[0281] The heat dissipation member 150 may be located between the vibration device 530 of the sound generating module 500 and the display module 100. The heat dissipation member 150 according to an embodiment of the present disclosure may be attached to the rear surface of the display module 100 so as to overlap with the sound generating module 500 and may be coupled or connected to the vibration device 530 of the sound generating module 500. The heat dissipation member 150 may be disposed on the rear surface of the display module 100 so as to overlap with the vibration device 530 and may diffuse heat generated when the vibration device 530 is driven toward the display module 100, thereby preventing heat-induced performance degradation of the vibration device 530. Furthermore, the heat dissipation member 150 may have a larger dimension than the vibration device 530 relative to the center portion of the vibration device 530 and may diffuse heat generated when the vibration device 530 is driven over a wide area, thereby preventing heat from being concentratedly transferred to a localized area of ​​the display module 100 that overlaps with the sound generating module 500. Consequently, localized brightness unevenness of the display module 100 may be prevented or minimized.

[0282] According to some embodiments of the present disclosure, the heat dissipation member 150 may include one of aluminum (Al), copper (Cu), silver (Ag), and magnesium (Mg), or an alloy thereof, or may include a metal material having high thermal conductivity like an alloy thereof, but is not limited thereto. The heat dissipation member 150 may be referred to as a heat sink, a heat dissipation layer, a heat dissipation plate, a heat sink, a heat conductive sheet, a heat conductive layer, or a heat conductive plate, but the term is not limited thereto.

[0283] Therefore, the display device according to an embodiment of the present disclosure can output sound PVS to the front area FD based on the vibration of the display module 100 (e.g., the display panel 110) caused by the vibration of the sound generating module 500, thereby enhancing the immersive experience of the viewer watching the image displayed by the display device.

[0284] Furthermore, in the display apparatus according to the embodiment of the present disclosure, since the sound PVS is generated based on the vibration of the display module 100 , a separate speaker may not be provided, thereby enhancing the degree of freedom in design of the set and arrangement of elements.

[0285] In addition, since the sound generating module 500 is set in the gap space GS between the display module 100 and the back cover 300, the rear surface of the sound generating module 500 can be covered by the back cover 300. Therefore, the display device according to the embodiment of the present disclosure can have a simple back design, in which a portion or the rear surface of the sound generating module 500 is not exposed or visible to the user, thereby improving the rear appearance design of the display device.

[0286] In addition, in the display device according to the embodiment of the present disclosure, the module structure 510 and the vibration device 530 of the sound generating module 500 can be modularized into one element and can be installed in the gap space GS between the display module 100 and the back cover 300 through a relatively simple component installation process. Therefore, the assembly performance of the sound generating module 500 can be improved during the assembly process performed on the display device, thereby improving the production yield.

[0287] Figures 3A to 3E A sound generation module according to an embodiment of the present disclosure is shown.

[0288] Reference Figures 2 to 3E , the sound generating module 500 according to an embodiment of the present disclosure may include a module structure 510 and a vibration device 530 .

[0289] The module structure 510 may be provided at the rear cover 300. For example, the module structure 510 may be provided at the rear cover 300 and may fix or support the vibration device 530. According to some embodiments of the present disclosure, the module structure 510 may be a metal plate including a metal material and having a plate shape. The module structure 510 may be referred to as a plate mechanism, a base structure, a base mechanism, a module support frame, or a module support plate, but the term is not limited thereto.

[0290] The module structure 510 can be disposed on or fixed to the rear cover 300 using the first member 410 (or module fixing member). The rear surface of the module structure 510 can be covered by the rear cover 300 and thus can be hidden and not directly exposed at the outermost rear surface of the display device. For example, the rear surface of the module structure 510 can be completely covered by the rear cover 300 and thus can be hidden and not directly exposed at the outermost rear surface of the display device.

[0291] The first member 410 according to some embodiments of the present disclosure may be a double-sided adhesive member between the module structure 510 and the back cover 300. The double-sided adhesive member may be a double-sided tape or a double-sided adhesive foam tape, but is not limited thereto. One surface (or front surface) of the first member 410 may be coupled to or disposed on the back surface of the module structure 510, and the other surface (or rear surface) of the first member 410 may be disposed on or fixed to the back cover 300 (e.g., the front surface of the first back cover 310). For example, the other surface of the first member 410 may be fixed to or disposed on the front surface of the first back cover 310 in a state where the lower protective sheet is peeled off from it.

[0292] According to some embodiments of the present disclosure, the first member 410 may be coupled (or modularized) to the rearmost surface of the sound generating module 500, which is modularized into one element, to facilitate assembly between the sound generating module 500 and the display module 100, and may be protected by a lower protective sheet. For example, the lower protective sheet may be referred to as a lower peeling sheet or a backing, but the term is not limited thereto.

[0293] According to some embodiments of the present disclosure, the double-sided adhesive member serving as the first member 410 may further include a heat transfer material. The heat transfer material may quickly transfer the heat generated in the sound generating module 500 to the back cover 300, thereby dissipating the heat of the sound generating module 500 toward the back cover 300, thereby preventing or minimizing local brightness unevenness of the display module 100 caused by heat generated during the driving of the sound generating module 500 being locally transferred to the area of ​​the display module 100 that overlaps with the sound generating module 500. According to some embodiments of the present disclosure, the heat transfer material may include conductive particles or a conductive layer, but is not limited thereto. For example, a double-sided adhesive member including a heat transfer material may be referred to as a heat transfer tape or a heat dissipation tape, but the term is not limited thereto.

[0294] The vibration device 530 may be provided at the module structure 510 and may vibrate the display module 100. For example, the vibration device 530 may be provided at the module structure 510 and may vibrate the display panel 110. By using the module integration member 520, the vibration device 530 may be integrally provided with the module structure 510 or fixed to the module structure 510.

[0295] The vibration device 530 may include a sound device or a vibration generating device that vibrates the display module 100 based on an electrical signal. For example, the vibration device 530 may be configured to vibrate the display module 100 using an electric current (or voice current) applied thereto based on Fleming's left-hand rule. The vibration device 530 may be referred to as a sound generating unit, a sound generating module, a vibration generating module, a vibration generating unit, an actuator, an exciter, or a transducer, but the term is not limited thereto.

[0296] The vibration device 530 may include an actuator (or exciter) disposed in contact with the rear surface of the display module 100. For example, the vibration device 530 including the actuator may include a bottom plate 531, a magnet 532, a center pole 533, a bobbin 534, a coil 535, a frame 536, and a damper 537. For example, the vibration device 530 may be a vibration device including a voice coil, but the term is not limited thereto.

[0297] The bottom plate 531 may be provided on or fixed to the module structure 510 and may be the main body of the vibration device 530. The bottom plate 531 may support each of the magnet 532, the center pole 533, and the frame 536. The bottom plate 531 may include a metallic material having magnetism, such as iron (Fe). The bottom plate 531 may be referred to as a lower plate, a base, or a yoke, but the term is not limited thereto.

[0298] The bottom plate 531 may include a groove portion accommodating the magnet 532 and the bobbin 534. For example, the groove portion may be concavely provided from the upper surface of the bottom plate 531 to have a circular shape.

[0299] By using the module integration member 520 , the bottom plate 531 may be provided integrally with or at the module structure 510 .

[0300] The module integration component 520 may be an adhesive component. The adhesive component may be provided between the extension portion (or fixing portion) 531a of the bottom plate 531 and the module structure 510. Therefore, the bottom plate 531 may be provided at the module structure 510. The module integration component 520 including the adhesive component may be an adhesive or a double-sided tape, but is not limited thereto.

[0301] According to another embodiment of the present disclosure, the module integration member 520 may include a plurality of screws that pass through the extension portion 531 a of the bottom plate 531 and may be fastened to the module structure 510 .

[0302] According to another embodiment of the present disclosure, the module integrated component 520 may include a bolt and a nut. The nut may be provided at or fixed to the module structure 510 that overlaps with the extension 531a of the base plate 531. The bolt may pass through the extension 531a of the base plate 531 and may be fastened to the nut. The nut according to some embodiments of the present disclosure may be a self-tightening nut provided at the module structure 510, but is not limited thereto. The self-tightening nut may be nut.

[0303] The magnet 532 , the center pole 533 , the bobbin 534 , and the coil 535 may be referred to as a magnetic circuit unit or a magnetic vibration unit, which is mounted on the bottom plate 531 to vibrate the display module 100 .

[0304] The magnetic circuit unit according to some embodiments of the present disclosure may have an external or dynamic magnetic type structure, in which the magnet 532 is disposed outside the coil 535, or may have an internal magnetic type or micro structure, in which the magnet 532 is disposed inside the coil 535. The vibration device 530 including the magnetic circuit unit having the internal magnetic type structure may have an overall smaller size and low leakage flux. The vibration device 530 according to some embodiments of the present disclosure may have an external magnetic type or an internal magnetic type structure. Hereinafter, an example in which the vibration device 530 has an internal magnetic type will be described.

[0305] The magnet 532 according to some embodiments of the present disclosure may be inserted into or accommodated in the groove portion of the bottom plate 531. The magnet 532 may be a permanent magnet having a cylindrical shape that can be inserted into or accommodated in the bobbin 534. According to some embodiments of the present disclosure, the magnet 532 may be implemented as a sintered magnet such as barium ferrite, and the material of the magnet 532 may include Fe2O3, BaCO3, neodymium magnet, strontium ferrite (Fe2O3) with improved magnetic components, and the like. 12 O 19 The neodymium magnet may be one or more of a cast magnet including Sr, an alloy including Al, nickel (Ni), and cobalt (Co). For example, the neodymium magnet may be neodymium-iron-boron (Nd-Fe-B), but is not limited thereto.

[0306] The bobbin 534 according to some embodiments of the present disclosure may be provided on the base plate 531 and surround the magnet 532. The bobbin 534 may have a circular or oval shape, but is not limited thereto. The oval may be an elliptical shape, a rectangular shape with rounded corners, or a non-circular curved shape having a width different from its height, but the present embodiment is not limited thereto. For example, in the bobbin 534 having an oval shape, the ratio of the major axis diameter to the minor axis diameter may be set to 1.3:1 to 2:1. The bobbin 534 having an oval shape may improve the sound of the high-pitched sound band better than a circular shape, and may reduce the occurrence of heat caused by vibration, thereby having excellent heat dissipation characteristics.

[0307] The coil 535 according to some embodiments of the present disclosure can be wound around the outer circumferential surface of the bobbin 534 and can be provided with a sound generating current (or voice current) from the outside. The coil 535 can be lowered or raised together with the bobbin 534. The coil 535 can be referred to as a voice coil. When current is applied to the coil 535, the entire portion of the bobbin 534 can move up and down based on the applied magnetic field generated around the coil 535 and the external magnetic field generated around the magnet 532 according to Fleming's left-hand rule, and can generate sound PVS or sound waves based on the vibration of the display module 100 caused by the vertical movement (or vibration) of the bobbin 534.

[0308] According to an embodiment of the present disclosure, when coil 535 is wound around the outer circumferential surface of bobbin 534, heat generated in coil 535 can be transferred to bobbin 534. Coil 535 can also be made of a material with relatively good heat dissipation properties, thereby reducing image quality defects affecting display panel 110 caused by heat from bobbin 534. Furthermore, since bobbin 534 vibrates up and down, horizontal vibration may occur due to vertical vibration, and the horizontal vibration of bobbin 534 may be affected by the weight of bobbin 534. The weight of bobbin 534 may be affected by the weight of coil 535. Therefore, when the weight of coil 535 is reduced, the horizontal vibration of bobbin 534 can be reduced. Therefore, considering the heat transferred to bobbin 534 and the horizontal vibration of bobbin 534, coil 535 can have relatively good heat dissipation properties because its thermal conductivity is superior to that of copper, a typical coil material. Furthermore, coil 535 can be made of aluminum, a material that has relatively good heat dissipation properties and is relatively lightweight compared to copper.

[0309] In addition, in aluminum, since oxides are formed in the air, welding may not be easy to perform when manufacturing the vibration device 530. Therefore, the coil 535 according to the embodiment of the present disclosure may include an Al layer (or a first metal layer) for heat dissipation and a metal covering layer (or a second metal layer) surrounding the Al layer. The metal covering layer may include one of Cu, Ag and gold (Au). For example, the coil 535 may be a copper-clad aluminum wire covered with copper. The metal covering layer can be formed as a thin film type outside the first metal layer, and therefore, it will not have a great impact on the weight increase of the coil 535. Therefore, compared with a coil including only Cu or Cu wire, the weight of the coil 535 according to the embodiment of the present disclosure can be reduced by about 60%.

[0310] According to some embodiments of the present disclosure, the bobbin 534 may include a structure comprising a material obtained by processing pulp or paper, Al or Mg or alloys thereof, or a synthetic resin such as polyimide. For example, the bobbin 534 may be implemented using a polyimide film having relatively good heat dissipation characteristics and being relatively lightweight, thereby preventing image quality defects of the display panel 110 caused by heat generated in the coil 535.

[0311] The polyimide film can have physical properties that remain unchanged over a wide temperature range of -273°C to -400°C, and can exhibit heat resistance, electrical insulation, flexibility, and non-flammability. Furthermore, due to its excellent thermal and mechanical strength, the polyimide film can enhance the reliability of the bobbin 534 and, due to its excellent heat dissipation properties, can reduce the generation of heat caused by vibration of the bobbin 534. For example, the polyimide film can be KAPTON, or a condensate of pyromellitic dianhydride and 4,4'-oxydianiline, but is not limited thereto.

[0312] The center pole 533 may be accommodated or inserted in the bobbin 534 and may guide the ascent or descent of the bobbin 534. For example, since the center pole 533 is accommodated or inserted in the bobbin 534, the outer circumferential surface of the center pole 533 may be surrounded by the bobbin 534. The center pole 533 may be referred to as an elevating guide or a pole piece, but the term is not limited thereto.

[0313] The frame 536 may be provided at the front edge (or front periphery) of the bottom plate 531 and may support the damper 537. The frame 536 according to some embodiments of the present disclosure may be provided at the front edge of the bottom plate 531 to have a certain height and a shape identical to that of the bobbin 534. According to another embodiment of the present disclosure, the frame 536 may include a hollow portion provided at the front edge of the bottom plate 531 to have a certain height and a shape identical to that of the bobbin 534.

[0314] The damper 537 may be disposed or connected between the frame 536 and the magnetic circuit unit. For example, the damper 537 may be disposed or connected between the frame 536 and the bobbin 534. The damper 537 may be referred to as a spider, a suspension, or an edge member, but the term is not limited thereto.

[0315] One end or a portion of the damper 537 according to some embodiments of the present disclosure may be connected to the 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 may have a pleated structure between one end and the other end thereof, and may contract and relax based on the vertical movement of the bobbin 534 to control the vibration of the bobbin 534. The damper 537 may be connected between the bobbin 534 and the frame 536, and may utilize a restoring force to limit the vibration distance of the bobbin 534. For example, when the bobbin 534 vibrates a certain distance or more or a certain distance or less, the bobbin 534 may be restored to its original position by the restoring force of the damper 537.

[0316] Since the vibration device 530 is arranged between the display module 100 and the back cover 300, the vibration device 530 should have a relatively thin thickness in order to further reduce the thickness of the display device or make the display device slimmer. As a result, when the height (or thickness) of the bobbin 534 is reduced, the sound pressure level may be reduced. Therefore, in order to solve the problem of reducing the sound pressure level due to the reduction in the height of the bobbin 534, the inventors have designed a structure in which the area of ​​the damper 537 arranged near the bobbin 534 is wider. When the area of ​​the damper 537 is expanded, the inventors have realized that the space for setting the circuit for applying current to the coil 535 becomes narrower, resulting in interference between the circuit and the damper 537. Therefore, through various experiments, the inventors have configured a damper 537 formed by a conductor and performing the function of a circuit.

[0317] The damper 537 according to some embodiments of the present disclosure may include a metal material electrically connected to the coil 535. For example, the damper 537 may be formed of stainless steel or copper (Cu), but is not limited thereto.

[0318] The vibration device 530 according to some embodiments of the present disclosure may further include a bobbin protection member 538 .

[0319] The bobbin protection member 538 may be provided on the front surface (or front end) of the bobbin 534 and may transmit the lifting motion (or vibration) of the bobbin 534 to the rear surface of the display module 100. The bobbin protection member 538 according to some embodiments of the present disclosure may have a ring shape provided on the front surface of the bobbin 534, a disc shape covering the entire front surface of the bobbin 534, or a hat shape surrounding the front surface and upper outer surface of the bobbin 534, but the shape is not limited thereto. For example, the bobbin protection member 538 may be referred to as a bobbin ring, but the term is not limited thereto.

[0320] The sound generating module 500 according to an embodiment of the present disclosure may further include a connection member 550 .

[0321] The connecting member 550 may be provided between the module structure 510 and the display module 100. The connecting member 550 according to some embodiments of the present disclosure may be provided between the front edge portion (or front peripheral portion) of the module structure 510 and the rear edge portion (or rear peripheral portion) of the display module 100. For example, the connecting member 550 may be a double-sided tape or a double-sided foam tape, but is not limited thereto. The connecting member 550 may provide a vibration space surrounding the vibration device 530 between the module structure 510 and the display module 100. The vibration space may be referred to as a sound pressure space, a sound box, a sound portion, a resonance box, or a resonance portion, but the term is not limited thereto.

[0322] The sound generating module 500 according to an embodiment of the present disclosure may further include a vibration transferring member 570 .

[0323] The vibration transferring member 570 may be connected or coupled to each of the connection member 550 and the vibration device 530 , and may vibrate based on the vibration of the vibration device 530 to transfer the vibration of the vibration device 530 to the display module 100 .

[0324] According to some embodiments of the present disclosure, the rear edge portion or rear peripheral portion of the vibration transfer member 570 can be connected or coupled to the connecting member 550, and the rear central portion of the vibration transfer member 570 can be coupled to the front surface of the bobbin 534 of the vibration device 530, or can be coupled to the bobbin protection member 538 of the vibration device 530.

[0325] The vibration transfer member 570 according to some embodiments of the present disclosure may be formed of one or more materials of aluminum (Al), magnesium (Mg) alloy, Mg-lithium (Li) alloy and aluminum alloy, but is not limited thereto. For example, the Mg alloy may include one or more materials of Al, zinc (Zn) and manganese (Mn). The Mg alloy may be the lightest material among the metal materials that can be used as the vibration plate of the speaker, may have a relatively high non-rigidity (rigidity / specific gravity) and a relatively high vibration damping capacity (the ability to absorb and gradually reduce vibration), and may have good dimensional stability against temperature changes and the passage of time.

[0326] According to some embodiments of the present disclosure, the front surface of the vibration transferring member 570 may be coupled or connected to the rear surface of the display module 100 using the second member 430 (or module adhesive member).

[0327] The second member 430 may be a double-sided adhesive member between the display module 100 and the vibration transfer member 570. The double-sided adhesive member may be, but is not limited to, a double-sided tape or double-sided foam tape. One surface (or front surface) of the second member 430 may be 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 may be disposed on or coupled to the front surface of the vibration transfer 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 detached.

[0328] According to some embodiments of the present disclosure, in order to facilitate assembly between the sound generating module 500 and the display module 100, the second member 430 may be coupled (or modularized) to the uppermost surface of the sound generating module 500, which is modularized into one element, and may be protected by an upper protective sheet. For example, the upper protective sheet may be referred to as an upper peeling sheet or a top liner, but the term is not limited thereto.

[0329] For example, all of the vibration transfer members 570 and the second member 430 may be omitted. For example, the sound generating module 500 may include an upper protective sheet coupled or connected to each of the connecting member 550 and the vibration device 530. The upper protective sheet may be coupled or connected to each of the connecting member 550 and the vibration device 530 to cover the entire front surface of the sound generating module 500. Thus, during the transfer process after the sound generating module 500 is modularized into one element, each of the vibration device 530 and the connecting member 550 of the sound generating module 500 can be prevented from being exposed to the outside, and particles such as dust can be prevented from penetrating into the sound generating module 500. The 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.

[0330] Therefore, the sound generating module 500 according to the embodiment of the present disclosure can be arranged between the display module 100 and the back cover 300 in a state where the module structure 510 and the vibration device 530 are modularized into one element. Therefore, by using the display module 100 as a vibration plate, the sound PVS based on the vibration of the display panel 110 can be output, and the outermost rear surface of the display device can be not exposed, thereby improving the rear appearance design of the display device.

[0331] Reference Figure 3B and Figure 3C , an adhesive member 522 may be provided between the vibration device 530 and the module structure 510. The adhesive member 522 may include one or more of a double-sided tape, a double-sided adhesive foam tape, a double-sided adhesive pad, a double-sided adhesive foam pad, and an adhesive member, but is not limited thereto. When the adhesive member 522 is provided, the assembly process may be simplified compared to screws or nuts and bolts and holes for fastening screws or nuts and bolts or extensions of the plate may not be required, thereby providing a thinner vibration device. The description of the vibration device is the same as above with reference to Figure 3A The descriptions given are the same, so the descriptions thereof are omitted.

[0332] Reference Figure 3B , the vibration device 530 can be arranged asymmetrically. When the vibration device 530 is arranged asymmetrically, the dip phenomenon of a specific frequency can be reduced. For example, when standing waves appear in the upper, lower, left, and right parts relative to the vibration device 530, the dip phenomenon may appear in the upper, lower, left, and right parts, but when the vibration device 530 is arranged asymmetrically, the phenomenon that the standing waves appear in the upper, lower, left, and right parts at the same time can be reduced. Therefore, the dip phenomenon can be reduced, thereby further enhancing the sound characteristics.

[0333] Reference Figure 3D and Figure 3E, the back cover 300 may include a first back cover 310 and a second back cover 350. The description of the first back cover 310 and the second back cover 350 is the same as that of the above reference Figure 2 The descriptions given are the same, and therefore, descriptions thereof are omitted.

[0334] Reference Figure 3D , the vibration device 530 can be housed in the first back cover 310. For example, the vibration device 530 can be located at the removed portion of the first back cover 310. The first back cover 310 can be attached to the vibration device 530 via an adhesive member 522. The adhesive member 522 can be located between the vibration device 530 and the second back cover 350. As another example, the adhesive member 522 can also be located between the vibration device 530 and the first back cover 310. For example, the adhesive member 522 can also be located between the extension 531a of the bottom plate 531 and the first back cover 310. The adhesive member 522 can include one or more of double-sided tape, double-sided foam tape, double-sided adhesive pad, double-sided foam pad, and adhesive, but is not limited thereto. A portion of the first back cover 310 can be removed, and the vibration device 530 can be located at the removed area of ​​the first back cover 310. Therefore, the thickness of the vibration device 530 can be reduced, thereby reducing the thickness of the display device. Furthermore, when the vibration device 530 is disposed adjacent to the first back cover 310 and / or the second back cover 350, abnormal vibrations may occur when the vibration device 530 vibrates. Therefore, the vibration device 530 may be separated from the first back cover 310 and / or the second back cover 350 by a certain interval or distance D. For example, the vibration device 530 may be separated from the first back cover 310 and / or the second back cover 350 by the interval or distance D. For example, the interval or distance D may be 1 mm or greater, but is not limited thereto.

[0335] Reference Figure 3EThe vibration device 530 may be housed between the first back cover 310 and the second back cover 350. For example, the bottom plate 531 of the vibration device 530 may have an exposed surface. The bottom plate 531 of the vibration device 530 may be disposed between the first back cover 310 and the second back cover 350. The bottom plate 531 of the vibration device 530 may be configured to penetrate the first back cover 310 and the second back cover 350. An adhesive member 522 may be disposed between the vibration device 530 and the first back cover 310. For example, the adhesive member 522 may be disposed between the extension 531a of the bottom plate 531 and a side of the first back cover 310. The adhesive member 522 may include, but is not limited to, one or more of double-sided tape, double-sided foam tape, double-sided adhesive pad, double-sided foam pad, and adhesive. Since the bottom plate 531 of the vibration device 530 is configured to have an exposed surface, the thickness of the vibration device 530 can be reduced, thereby reducing the thickness of the display device. Furthermore, when the vibration device 530 is disposed adjacent to the first and second back covers 310 and 350, abnormal vibrations may occur when the vibration device 530 vibrates. Therefore, the vibration device 530 may be separated from the first and second back covers 310 and 350 by a certain interval or distance D. For example, the vibration device 530 may be separated from the first and second back covers 310 and 350 by the interval or distance D. For example, the interval or distance D may be 1 mm or greater, but is not limited thereto.

[0336] Figure 4 Shown Figures 3A to 3E The connecting components shown.

[0337] Reference Figures 3A to 3E and Figure 4 , the connection member 550 according to some embodiments of the present disclosure may include first to fourth connection parts 551 to 554. The first to fourth connection parts 551 to 554 may be first to fourth coupling parts, respectively, but these terms are not limited thereto.

[0338] Each of the first to fourth connection portions 551 to 554 may have a linear shape having a certain width and length, and may be disposed between the module structure 510 and the vibration transfer member 570 .

[0339] According to some embodiments of the present disclosure, Figure 4 In the plan view of the module structure 510 shown, the module structure 510 may include a first front edge portion or a first front surface peripheral portion (or left side), a second front edge portion or a second front surface peripheral portion (or right side) parallel to the first front edge portion, a third front edge portion or a third front surface peripheral portion (or upper side) located between a portion of the first front edge portion and a portion of the second front edge portion, and a fourth front edge portion or a fourth front surface peripheral portion (or lower side) parallel to the third front edge portion and located between another portion of the first front edge portion and another portion of the second front edge portion.

[0340] The first connection portion 551 may be provided at a first front edge portion of the module structure 510, and the second connection portion 552 may be provided at a second front edge portion of the module structure 510. The third connection portion 553 may be provided at a third front edge portion of the module structure 510, and the fourth connection portion 554 may be provided at a fourth front edge portion of the module structure 510.

[0341] Each of the first to fourth connection portions 551 to 554 may have a structure separated from the corresponding corner portion of the module structure 510. For example, each of the first to fourth connection portions 551 to 554 may have a quadrilateral (quadrangular) strip shape that is not separated therefrom, and in this case, materials other than the connection member 550 among the raw materials for forming the connection member 550 may be wasted, resulting in an increase in material cost.

[0342] A portion of each of the first to fourth connection parts 551 to 554 can be arranged to contact an adjacent connection part among the first to fourth connection parts 551 to 554 at a corresponding corner of the module structure 510, so that external leakage of sound waves generated in the vibration space defined by the connecting member 550 can be minimized.

[0343] At least one of the first to fourth connection portions 551 to 554 may include a plurality of bent portions 553 a and 554 a facing the vibration device 530 .

[0344] When the display module 100 vibrates using the vibration device 530, the sound waves generated can diffuse radially from the center of the vibration generating device and propagate. These sound waves can be referred to as progressive waves. The progressive waves can be reflected by the connecting member 550 to generate reflected waves, which can propagate in the opposite direction of the progressive waves. The reflected waves overlap and interfere with the progressive waves and do not propagate, thereby generating standing waves that remain stationary at specific locations. Standing waves reduce sound pressure, thereby degrading sound output characteristics. Therefore, curved portions 553a and 554a can be provided in the connecting member 550 to reduce the phenomenon of reduced sound pressure caused by standing waves generated by the interference between the reflected and progressive waves. For example, the curved portions 553a and 554a can be provided at the location where the levels of each of the progressive and reflected waves are highest, or in at least one of the first to fourth connecting portions 551 to 554 where the strongest sound waves reach. For example, the bent portions 553a and 554a may be disposed on an extension line EL of the center portion of the vibration device 530 to face the center portion of the vibration device 530 , thereby minimizing a phenomenon in which sound pressure is reduced by standing waves.

[0345] According to some embodiments, the bends 553a and 554a may be provided in the third connection portion 553 and the fourth connection portion 554. In addition, the bends 553a and 55a may have a certain tilt angle θ relative to the horizontal direction (or width direction) X of the display device. The tilt angle θ of each of the bends 553a and 554a according to some embodiments of the present disclosure may vary based on the degree to which the standing wave is suppressed, and may be set to vary within a range of 10 to 30 degrees, for example. For example, when the vibration device 530 outputs a sound in a bass band or the output of the vibration device 530 is large, the bends 553a and 553b may have a relatively large tilt angle θ. For example, when the vibration device 530 outputs a sound in a treble band or the output of the vibration device 530 is small, the bends 553a and 554a may have a relatively small tilt angle θ.

[0346] The third connection portion 553 and the fourth connection portion 554 may have a structure that is left-right symmetrical with respect to the bent portions 553a and 554a. The bent portions 553a and 554a may have an open structure on the extension line EL of the center portion of the vibration device 530, but are not limited thereto, and may have a V-shaped closed structure. When the bent portions 553a and 554a have an open structure on the extension line EL of the center portion of the vibration device 530, the material cost can be reduced compared to a closed structure. In addition, according to the sound characteristic experiment, the inventors have confirmed that there is very little or no difference in sound characteristics when the bent portions 553a and 554a have an open structure on the extension line EL of the center portion of the vibration device 530 and when the bent portions 553a and 554a have a closed structure on the extension line EL.

[0347] In addition, the bent portions 553 a and 554 a may be identically or similarly applied to the first connection portion 551 and the second connection portion 552 .

[0348] At least one of the first to fourth connection parts 551 to 554 may include at least one protrusion 555 and 556 facing the vibration device 530. For example, the at least one protrusion 555 and 556 may be provided in the first and second connection parts 551 and 552, respectively, to face the center portion of the vibration device 530. The at least one protrusion 555 and 556 may absorb (trap) reflected waves and reduce a buoyancy or sinking phenomenon caused by standing waves, thereby minimizing a phenomenon of reduced sound pressure.

[0349] Figure 5A and Figure 5B is a diagram for describing a damper structure of a vibration device according to an embodiment of the present disclosure.

[0350] Figure 5A A vibration device having a monomer type structure is shown, and Figure 5B A vibration device having a dual-body structure is shown. The dual-body structure may be referred to as a dual array structure. A vibration device according to the present disclosure may be configured as a dual array structure or more array structures, and for example, may be configured as a quad array structure or a hexa array structure.

[0351] Reference Figure 3A-Figure 3E and Figure 5A In the vibration device 530 according to an embodiment of the present disclosure, the damper 537 may be connected to the bobbin 534 and the frame 536 provided on the bottom plate 531 .

[0352] The damper 537 may be configured to act as a signal line or signal wiring and thus may include a first damper 537-1 that receives positive power (or positive voice signal) and a second damper 537-2 that receives negative power (or negative voice signal).

[0353] For example, the damper 537 may be divided vertically relative to the width direction X. For example, relative to a center line passing through the center portion of the bobbin 534 along the width direction X, 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 line terminal 530p, and the second damper 537-2 may be electrically connected to the second line terminal 530m. The line terminals may be referred to as line pads, but these terms are not limited thereto. For example, the first line terminal 530p may be a positive (+) terminal, and the second line terminal 530m may be a negative (-) terminal.

[0354] According to some embodiments of the present disclosure, each of the first damper 537 - 1 and the second damper 537 - 2 may include an inner portion 537 a , an outer portion 537 b , and a plurality of damping parts 537 c .

[0355] The inner portion 537a may have a semicircular (or oval) shape and may be coupled or connected to the bobbin 534. For example, the center portion of the inner portion 537a may have a semicircular (or oval) shape. The inner portions 537a of the first damper 537-1 and the second damper 537-2 may be spaced (or separated) from each other on a center line passing through the center portion of the bobbin 534 in the width direction X, thereby being electrically disconnected from each other.

[0356] The outer portion 537b may have a semicircular (or oval) shape to surround the inner portion 537a and may be disposed on or coupled to the frame 536. For example, the center portion of the outer portion 537b having the semicircular (or oval) shape may be the same as the center portion of the bobbin 534. The outer portions 537b of the first damper 537-1 and the second damper 537-2 may be spaced (or separated) from each other on a center line passing through the center portion of the bobbin 534 in the width direction X, thereby being electrically disconnected from each other.

[0357] Each of the plurality of damping portions 537c can be connected between the inner portion 537a and the outer portion 537b to have a certain interval or distance (or equal interval). Each of the plurality of damping portions 537c according to some embodiments of the present disclosure can have an S-shaped or zigzag shape. Each of the plurality of damping portions 537c can contract and relax based on the vertical movement of the inner portion 537a (which is based on the vertical movement of the bobbin 534) to control the vibration of the bobbin 534. For example, each of the plurality of damping portions 537c can have a length that is relatively longer than the shortest distance between the frame 536 and the bobbin 534. Therefore, in order to reduce the thickness of the vibration device 530 and improve the performance of the magnet 532, the length of the damper 537 can be set to be longer.

[0358] According to some embodiments of the present disclosure, one end or a portion of each of the plurality of damping portions 537 c may be connected to the inner portion 537 a. For example, the connection between one end or a portion of each of the plurality of damping portions 537 c and the inner portion 537 a may be rounded into a curved shape, thereby preventing each of the damping portions 537 c from being torn apart by the vertical movement of the corresponding damping portion 537 c.

[0359] Reference Figure 3A-Figure 3E and Figure 5B , a vibration device 530 according to another embodiment of the present disclosure may include two sub-vibration devices 530a and 530b provided on a bottom plate 531. The vibration device 530 including the two sub-vibration devices 530a and 530b may be referred to as a dual-body type vibration device, but the term is not limited thereto.

[0360] In the dual-body type vibration device 530, the dampers 537 of the two sub-vibration devices 530a and 530b can be connected in parallel with each other. The damper 537 of each of the two sub-vibration devices 530a and 530b can be configured to act as a signal line or signal wiring, and thus can include a first damper 537-1 that receives positive power (or positive voice signal) and a second damper 537-2 that receives negative power (or negative voice signal).

[0361] According to some embodiments of the present disclosure, the damper 537 of each of the two sub-vibration devices 530a and 530b may be divided vertically with respect to the width direction X, and for example, with respect to a center line passing through the center portion of the bobbin 534 in the width direction X, the first damper 537-1 may be disposed above the center line, and the second damper 537-2 may be disposed below a portion of the center line. For example, the first damper 537-1 may be electrically connected to the first line terminal 530p, and the second damper 537-2 may be electrically connected to the second line terminal 530m.

[0362] According to some embodiments of the present disclosure, 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. The description of each of the first damper 537-1 and the second damper 537-2 is the same as that described above with reference to Figure 5A The descriptions given are the same, and therefore, duplicate descriptions are omitted.

[0363] The first dampers 537-1 of the two sub-vibration devices 530a and 530b may be electrically connected to each other in the central area of ​​the bottom plate 531, and the second dampers 537-2 of the two sub-vibration devices 530a and 530b may be electrically connected to each other in the central area of ​​the bottom plate 531. Therefore, the dampers 537 of the two sub-vibration devices 530a and 530b may be connected in parallel to each other.

[0364] In a vibration device 530 according to another embodiment of the present disclosure, each of the first line terminal 530p and the second line terminal 530m can be electrically connected to an audio amplifier (or audio processor) via a signal cable (or signal transmission member). Therefore, the position of each of the first line terminal 530p and the second line terminal 530m exposed at the bottom plate 531 can be changed to a corner of the bottom plate 531 to facilitate electrical connection to the signal cable.

[0365] The vibration device 530 according to another embodiment of the present disclosure may further include first to fourth brackets 539 a to 539 d .

[0366] Each of the first to fourth brackets 539a to 539d may be disposed on or coupled to a corresponding side surface of the bottom plate 531. For example, the first bracket 539a may be disposed on a first side surface (or first short side) of the bottom plate 531, and the second bracket 539b may be disposed on a second side surface (or second short side) of the bottom plate 531. The third bracket 539c may be disposed on a third side surface (or first long side) of the bottom plate 531, and the fourth bracket 539d may be disposed on a fourth side surface (or second long side) of the bottom plate 531.

[0367] Each of the first to fourth brackets 539 a to 539 d may be fixed to the module structure 510 through the module integrating member 520 , and thus, the bottom plate 531 may be disposed at or fixed to the module structure 510 .

[0368] For example, each of the first to fourth brackets 539a to 539d may be fixed to or provided on the module structure 510 by using a module integration member 520 such as a double-sided tape. For example, one surface of each of the first to fourth brackets 539a to 539d facing the module structure 510 may be provided as a flat surface structure to increase the bonding area with the double-sided tape.

[0369] As another example, each of the first to fourth brackets 539a to 539d may be fixed to or provided on the module structure 510 using a module integration member 520 such as an adhesive (or bonding member). For example, one surface of each of the first to fourth brackets 539a to 539d facing the module structure 510 may be provided with a concave-convex structure including a plurality of rib patterns RP for controlling adhesive flow and preventing adhesive overflow.

[0370] As another example, each of the first to fourth brackets 539a to 539d may be fixed to or provided at the module structure 510 by using the module integrating member 520 such as a plurality of screws. For example, each of the first to fourth brackets 539a to 539d facing the module structure 510 may include at least one hole SH through which at least one screw passes.

[0371] Each of the first to fourth brackets 539a to 539d may fundamentally include at least one hole SH, and for compatibility based on a modular process performed between the vibration device 530 and the module structure 510 by using the module integration component 520, one surface of each of the first to fourth brackets 539a to 539d may include a flat surface structure or a concave-convex structure.

[0372] Figure 6 A sound generating module according to another embodiment of the present disclosure is shown.

[0373] Figure 6 Shows adding heat dissipation structures to Figure 3A-Figure 3E Therefore, except for the elements related to the heat dissipation structure of the sound generating module, descriptions of the same elements will be briefly given or omitted below.

[0374] Reference Figure 2 and Figure 6 , a sound generating module 500 according to another embodiment of the present disclosure may include a module structure 510 and a vibration device 530 .

[0375] The module structure 510 may be a base structure of the sound generating module 500, and may be disposed on or fixed to the back cover 300 by using the first member 410. The module structure 510 may include a groove 510h overlapping with the vibration device 530.

[0376] The groove 510h may be formed to vertically pass through the module structure 510 in the vertical direction Z and may expose the rear surface of the vibration device 530 at the rear cover 300. For example, the groove 510h may have a circular, oval, or polygonal shape, but is not limited thereto. The groove 510h may be referred to as a through hole or a hole, but the term is not limited thereto.

[0377] The size of the groove 510h according to an embodiment of the present disclosure may be smaller than that of the rear surface of the vibration device 530. For example, the groove 510h according to an embodiment of the present disclosure may be a heat dissipation path through which heat generated in the vibration device 530 is transferred toward the back cover 300.

[0378] 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 vibration 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 vibration device 530, and may also be a heat dissipation path through which heat generated in the vibration device 530 is transmitted toward the back cover 300. In addition, the groove 510h according to another embodiment of the present disclosure can reduce the distance between the rear surface of the vibration device 530 and the back cover 300, thereby improving heat dissipation efficiency.

[0379] In addition to the module structure 510 including the groove 510h, the other structures are the same as Figure 3A-Figure 3E The modules shown have the same structure, so their repeated description can be omitted.

[0380] The vibration device 530 may be integrally provided with the module structure 510 or provided at the module structure 510 by using the module integration member 520 so as to overlap with the groove 510h of the module structure 510. The vibration device 530 may include an actuator (or exciter) provided to contact the rear surface of the display module 100. For example, the vibration device 530 including the actuator may include a bottom plate 531, a magnet 532, a center pole 533, a bobbin 534, a coil 535, a frame 536, a damper 537, and a hollow portion 530h.

[0381] The components of the vibration device 530 other than the bottom plate 531 and the hollow portion 530h are Figure 3A-Figure 3E The elements of the vibration device shown are the same, so their repeated description is omitted.

[0382] The rear surface of the bottom plate 531 according to an embodiment of the present disclosure may be disposed on the groove 510h of the module structure 510. For example, when the size of the groove 510h of the module structure 510 is smaller than that of the bottom plate 531, the rearmost surface of the bottom plate 531 may be stably placed at the module structure 510 and may be disposed on the groove 510h.

[0383] According to another embodiment of the present disclosure, the rear surface of the bottom plate 531 can be inserted into or accommodated in the groove 510h of the module structure 510. For example, when the size of the groove 510h of the module structure 510 is equal to or larger than the size of the bottom plate 531, a portion of the rear surface of the bottom plate 531 can be inserted into or accommodated in the groove 510h of the module structure 510. For example, the rearmost surface of the bottom plate 531 may not protrude outside the rearmost surface of the module structure 510 through the groove 510h of the module structure 510, but may be disposed in the groove 510h of the module structure 510. Therefore, the thickness of the sound generating module 500 can be reduced by the height (or depth) or insertion height (or depth) of the bottom plate 531 accommodated or inserted into the groove 510h of the module structure 510, thereby making the sound generating module slimmer.

[0384] At least one of the extension 531a (or brackets 539a to 539d) of the bottom plate 531 and the module integration component 520 can be configured so that a portion of the rear surface of the bottom plate 531 is accommodated or inserted into the recess 510h of the module structure 510. For example, the extension 531a (or brackets 539a to 539d) of the bottom plate 531 can have a relatively thin thickness, or extend from the upper surface of the bottom plate 531 to be spaced apart from the rear surface of the bottom plate 531 to the greatest extent possible, so that a portion of the rear surface of the bottom plate 531 is accommodated or inserted into the recess 510h of the module structure 510. Furthermore, the thickness of the module integration component 520 can be adjusted within a range that allows a certain portion of the rear surface of the bottom plate 531 to be accommodated or inserted into the recess 510h of the module structure 510.

[0385] The hollow portion 530h may pass through each of the bottom plate 531, the magnet 532, and the center pole 533 in the vertical direction Z to overlap with the groove 510h of the module structure 510. The hollow portion 530h may be a heat dissipation path through which heat generated by the driving of the vibration device 530 is dissipated toward the back cover 300, thereby increasing the sound pressure based on the driving of the vibration device 530 and reducing the weight of the vibration device 530. In addition, when the vibration space provided in the connecting member 550 is sealed, the sound pressure generated by the driving of the vibration 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 based on the driving of the vibration device 530 can be increased.

[0386] According to some embodiments of the present disclosure, the vibration device 530 may further include a plurality of plate holes 531h disposed in the base plate 531 and overlapping the recess 510h of the module structure 510. The plurality of plate holes 531h may pass through the base plate 531 in the vertical direction Z, thereby overlapping at least one of the bobbin 534 and the magnet 532. For example, the plate hole 531h overlapping the magnet 532 may be blocked during the manufacturing process of the vibration device 530. Therefore, the plate hole 531h may be disposed in the base plate 531 overlapping the bobbin 534. For example, each of the plurality of plate holes 531h may be radially disposed in the rear surface of the base plate 531, but this is not limited to this. The plate holes 531h may be referred to as vent holes, but this term is not limited to this. The plurality of plate holes 531h may additionally dissipate heat generated in the vibration device 530.

[0387] Therefore, the sound generating module 500 according to another embodiment of the present disclosure may include a groove 510h set in the module structure 510 and a hollow portion 530h and a plate hole 531h set in the vibration device 530, thereby enhancing the heat dissipation function and increasing the sound pressure generated in the vibration space based on the driving of the vibration device 530.

[0388] Figure 7 Shows coverage Figure 6 A back cover of a rear surface of a sound generating module according to another embodiment of the present disclosure is shown.

[0389] Figure 7 An embodiment in which a plurality of holes (or vent holes) are additionally provided in the back cover overlapping the sound generating module is shown. Therefore, hereinafter, descriptions of the same elements except for the elements related to the plurality of holes will be briefly given or omitted.

[0390] Reference Figure 2 、 Figure 6 and Figure 7 , the back 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 .

[0391] Each of the plurality of holes 300 h may be provided to vertically penetrate the entire second back cover 350 and the first back cover 310 of the back cover 300 in the thickness direction Z, and may overlap with the vibration device 530 .

[0392] The plurality of holes 300h may be radially arranged to overlap the hollow portion 530h provided in the vibration device 530. The plurality of holes 300h according to some embodiments of the present disclosure may be radially arranged at certain intervals or distances (or at equal intervals) relative to the center portion of the hollow portion 530h provided in the vibration device 530. For example, the plurality of holes 300h may be arranged at certain intervals on the circumferences of a plurality of concentric circles, which together with the hollow portion 530h provided in the vibration device 530 form a concentric shape.

[0393] According to some embodiments of the present disclosure, each of the plurality of holes 300h may have a certain width and a certain length, and these widths and lengths are set within a range that does not reduce the simple back design of the display device. When each of the plurality of holes 300h has a hole shape or a linear shape whose size can be easily seen in the back cover 300, the simple back design of the display device may not be achieved. Therefore, each of the plurality of holes 300h may have a size that allows external air of the display device to flow in or out through the sound generating module 500 or the hollow portion 530h provided in the vibration device 530, so that the simple back design of the display device is not reduced.

[0394] Figure 8 It is along Figure 1 Another schematic cross-sectional view taken along line II′ is shown, illustrating a display device according to another embodiment of the present disclosure.

[0395] Reference Figure 1 and Figure 8 , a display device according to another embodiment of the present disclosure may include one sound generating module 500 positioned between the display module 100 and the back cover 300 .

[0396] The display module 100 and the back cover 300 are Figure 2 and Figure 3A-Figure 3E The display module and rear cover shown are the same, so their repeated descriptions are omitted.

[0397] A sound generation module 500 can be Figure 2 and Figure 3A-Figure 3E The first sound generating module 500 - 1 and the second sound generating module 500 - 2 are modularly configured as one element.

[0398] According to some embodiments of the present disclosure, one sound generating module 500 may include a module structure 1510 , a first vibration device 530 - 1 , and a second vibration device 530 - 2 .

[0399] The module structure 1510 can be disposed on or fixed to the rear cover 300 by using the first member 410 (or the first module fixing member). The rear surface of the module structure 1510 can be completely covered by the rear cover 300 and thus can be hidden without being directly exposed to the outermost rear surface of the display device. Figure 2 and Figure 3A-Figure 3E The module structure 510 of each of the first sound generating module 500-1 and the second sound generating module 500-2 is configured as a panel structure. Figure 2 and Figure 3A-Figure 3E The modules shown have the same structure, so their repeated description is omitted.

[0400] The first vibration device 530-1 can be disposed in or fixed to the first area of ​​the module structure 1510 and can vibrate the display module 100 (e.g., the first area (or left area) of the display panel 110). For example, by using the module integration member 520, the first vibration device 530-1 can be disposed in or fixed to the first area of ​​the module structure 1510, or can be integrally provided with the module structure 1510. According to some embodiments of the present disclosure, the first vibration device 530-1 can be disposed in the center of the first area of ​​the module structure 1510, or can be disposed near the edge or periphery of the first area of ​​the module structure 1510.

[0401] The second vibration device 530-2 can be set in or fixed to the second area of ​​the module structure 1510, and can vibrate the display module 100 (for example, the second area (or right area) of the display panel 110). For example, by using the module integration component 520, the second vibration device 530-2 can be set in or fixed to the second area of ​​the module structure 1510, or can be set as a whole with the module structure 1510. According to some embodiments of the present disclosure, the second vibration device 530-2 can be set in the central part of the second area of ​​the module structure 1510, or can be set close to the edge or peripheral part of the second area of ​​the module structure 1510. For example, the second vibration device 530-2 can be set to be symmetrical with the first vibration device 530-1 relative to the central part of the module structure 1510.

[0402] In addition to each of the first vibration device 530-1 and the second vibration device 530-2 being provided as a single module structure 1510, each of the first vibration device 530-1 and the second vibration device 530-2 is similar to Figure 2 and Figure 3A-Figure 3E The vibration devices shown are the same, so their repeated description is omitted. In addition, each of the first vibration device 530-1 and the second vibration device 530-2 can have Figure 5A The monomer type structure shown is, but not limited thereto, and may have Figure 5B The dimeric type structure shown.

[0403] Figure 8 The sound generating module 500 shown includes two vibration devices 530-1 and 530-2, but is not limited thereto and may include three or more vibration devices. In the case of including three or more vibration devices, a stereo PVS of three or more channels can be output based on the vibration of each of the three or more vibration devices embedded in the sound generating module 500.

[0404] One sound generating module 500 may further include a connecting member 550 and a partitioning member 560 .

[0405] The connection member 550 may be provided between the module structure 1510 and the display module 100. For example, the connection member 550 may be provided between an edge or peripheral portion of the module structure 1510 and the display module 100. For example, the connection member 550 may be configured to completely surround the plurality of vibration devices 530-1 and 530-2 provided on or fixed to the module structure 1510.

[0406] A partition member 560 may be provided between the plurality of vibration devices 530-1 and 530-2 disposed on or fixed to the module structure 1510, and the partition member 560 may spatially separate the first and second regions of the module structure 1510. For example, the partition member 560 may include a first partition 561 and a second partition 562 disposed in parallel in a central region between the first and second regions of the module structure 1510. Based on vibrations generated in each of the first and second regions of the module structure 1510 in the display module 100 (e.g., the first and second regions of the display panel 110), the first and second partitions 561 and 562 may reduce the influence on the sound characteristics caused by the difference in the resonant frequencies of mid- and high-pitched sounds.

[0407] One sound generating module 500 may further include a vibration transferring member 1570 and a second member 430 .

[0408] The vibration transmitting member 1570 may be provided on or coupled to each of the plurality of vibration devices 530-1 and 530-2, the connecting member 550, and the partitioning member 560, and may vibrate based on the vibration of each of the plurality of vibration devices 530-1 and 530-2 to transmit the vibration of each of the plurality of vibration devices 530-1 and 530-2 to the display module 100 (e.g., the display panel 110). In addition to the vibration transmitting member 1570 being additionally coupled to each of the plurality of vibration devices 530-1 and 530-2 and the partitioning member 560, the vibration transmitting member 1570 and the partitioning member 560 may be coupled to each of the plurality of vibration devices 530-1 and 530-2. Figure 2 and Figure 3A-Figure 3E The vibration devices shown are the same, so their repeated description is omitted.

[0409] The second member 430 may be a double-sided adhesive member disposed between the display module 100 and the vibration transmitting member 570. The double-sided adhesive member may be a double-sided tape or a double-sided foam tape, but is not limited thereto. Figure 3A-Figure 3E The second member 430 shown is the same, and therefore, repeated description thereof is omitted.

[0410] Therefore, a display device according to another embodiment of the present disclosure may include a sound generating module 500, in which a module structure 1510 and a plurality of vibration devices 530-1 and 530-2 are modularized into one element, and thus, the assembly performance or assembly of the sound generating module 500 can be further improved in the process of assembling the modules, thereby improving the production yield of the display device.

[0411] Figure 9 Shown Figure 3A-Figure 3E The connecting members and separating members shown.

[0412] Reference Figure 8 and Figure 9 , the connection member 550 according to an embodiment of the present disclosure may include first to fourth connection parts 1551 to 1554 .

[0413] Each of the first to fourth connection portions 1551 to 1554 may be disposed between a front edge or periphery of the module structure 1510 and the display module 100 , or may be disposed between a front edge or periphery of the module structure 1510 and the vibration transfer member 1570 .

[0414] According to some embodiments of the present disclosure, each of the first to fourth connection portions 1551 to 1554 may have a linear shape having a specific width and length.

[0415] According to some embodiments of the present disclosure, Figure 9 In the plan view of the module structure 1510 shown, the module structure 1510 may include a first front edge portion or a first front surface peripheral portion (or left side), a second front edge portion or a second front surface peripheral portion (or right side) parallel to the first front edge portion, a third front edge portion or a third front surface peripheral portion (or upper side) located between a portion of the first front edge portion and a portion of the second front edge portion, and a fourth front edge portion or a fourth front surface peripheral portion (or lower side) parallel to the third front edge portion and located between another portion of the first front edge portion and another portion of the second front edge portion.

[0416] The first connection portion 1551 may be provided at a first front edge portion of the module structure 1510, and the second connection portion 1552 may be provided at a second front edge portion of the module structure 1510. The third connection portion 1553 may be provided at a third front edge portion of the module structure 1510, and the fourth connection portion 1554 may be provided at a fourth front edge portion of the module structure 1510.

[0417] Each of the first to fourth connection portions 1551 to 1554 may have a structure separated from a corresponding corner portion of the module structure 1510. For example, each of the first to fourth connection portions 1551 to 1554 may have a quadrilateral (quadrangular) band shape that is not separated therefrom, and in this case, materials other than the connection member 550 among the raw materials for forming the connection member 550 may be wasted, resulting in an increase in material cost.

[0418] A portion of each of the first to fourth connection portions 1551 to 1554 can be configured to contact adjacent connection portions among the first to fourth connection portions 1551 to 1554 at corresponding corners of the module structure 1510, so that external leakage of sound waves generated in the vibration space defined by the connecting member 550 can be minimized.

[0419] At least one of the first to fourth connection portions 1551 to 1554 may include a plurality of bent portions 1553 a and 1554 a facing the first and second vibration devices 530 - 1 and 530 - 2 .

[0420] Each of the plurality of curved portions 1553a and 1554a may be provided at a position where the level of each of the progressive wave and the reflected wave is highest, or may be provided in at least one connection portion to which the strongest sound wave reaches from the first connection portion 1551 to the fourth connection portion 1554. For example, each of the plurality of curved portions 1553a and 1554a may be provided on an extension line EL of the center portion of each of the first vibration device 530-1 and the second vibration device 530-2 so as to face the center portion of each of the first vibration device 530-1 and the second vibration device 530-2, thereby minimizing a phenomenon in which the sound pressure is reduced by the standing wave.

[0421] According to some embodiments of the present disclosure, a plurality of bent portions 1553a and 1554a may be provided in the third connection portion 1553 and the fourth connection portion 1554. In addition, the plurality of bent portions 1553a and 1554a may have a certain tilt angle θ relative to the horizontal direction (or width direction) X of the display device. The tilt angle θ of each of the plurality of bent portions 1553a and 1554a according to some embodiments of the present disclosure may vary based on the degree to which the standing wave is suppressed, and may be set to vary within a range of 10 to 30 degrees, for example.

[0422] Each of the plurality of bent portions 1553a and 1554a may have an open structure on an extension line EL of a center portion of a corresponding vibration device of the first and second vibration devices 530-1 and 530-2, but is not limited thereto and may have a V-shaped closed structure.

[0423] In addition, each of the plurality of bent portions 1553 a and 1554 a may be identically or similarly applied to at least one of the first connection portion 1551 and the second connection portion 1552 .

[0424] At least one of the first to fourth connecting portions 1551 to 1554 may include at least one protrusion 555 or 556 facing the corresponding vibration device in the first and second vibration devices 530-1 and 530-2. For example, the at least one protrusion 555 or 556 may be provided in the first and second connecting portions 1551 and 1552, respectively, to face the center of the corresponding vibration device in the first and second vibration devices 530-1 and 530-2. The at least one protrusion 555 or 556 may absorb reflected waves and reduce the rise or fall caused by standing waves, thereby minimizing the phenomenon of reduced sound pressure. The at least one protrusion 555 or 556 may be referred to as a first protrusion, but this term is not limited to this.

[0425] The partition member 560 may include a first partition 561 and a second partition 562 disposed in parallel in a central region between the first and second regions of the module structure 1510 .

[0426] Each of the first and second partitions 561 and 562 may be disposed between the third and fourth connection parts 1553 and 1554 in parallel with each of the first and second connection parts 1551 and 1552. For example, each of the first and second partitions 561 and 562 may have the same width as each of the first to fourth connection parts 1551 to 1554, but is not limited thereto.

[0427] An end portion of each of the first and second partitions 561 and 562 can approach the third connection portion 1553 in a state of contacting or not contacting the third connection portion 1553. An end portion of another portion of each of the first and second partitions 561 and 562 can approach the fourth connection portion 1554 in a state of contacting or not contacting the fourth connection portion 1554. The first and second partitions 561 and 562 can reduce the influence on sound characteristics caused by the difference in resonant frequency of medium and high-pitched sounds based on vibrations generated in each of the first and second regions of the module structure 1510 in the display module 100 (for example, the first and second regions of the display panel 110).

[0428] The first partition 561 and the second partition 562 according to some embodiments of the present disclosure may include at least one second protrusion 563 and 564 , respectively.

[0429] According to some embodiments of the present disclosure, at least one second protrusion 563 in the first partition 561 can be disposed in the first partition 561 so as to face the center of the first vibration device 530-1. At least one second protrusion 564 in the second partition 562 can be disposed in the second partition 562 so as to face the center of the second vibration device 530-2. The second protrusions 563 and 564 can have the same or different lengths as the first protrusions 555 and 556. For example, the second protrusions 563 and 564 can have a longer length than the first protrusions 555 and 556. The at least one second protrusion 563 and 564 can absorb reflected waves and reduce the rise or fall caused by standing waves, thereby minimizing the phenomenon of reduced sound pressure.

[0430] Figure 10 It is along Figure 1 Another cross-sectional view taken along line II' is shown. Figure 11 Shown Figure 10 Back cover shown.

[0431] Figure 10 An embodiment in which a module receiving portion is additionally provided in a rear cover according to an embodiment of the present disclosure is shown. Therefore, hereinafter, descriptions of the same elements except the module receiving portion and elements related thereto will be briefly given or omitted.

[0432] Reference Figure 10 and Figure 11 , the back cover 300 according to the embodiment of the present disclosure may further include at least one module receiving portion 370 in which at least one sound generating module 500 is received.

[0433] At least one module receiving portion 370 may be provided in the first back cover 310 of the back cover 300 and may be covered by the second back cover 350. For example, the at least one module receiving portion 370 may be provided to vertically pass through the first back cover 310 of the back cover 300 in the thickness direction Z and may be covered by the second back cover 350. In order to make the thickness of the display device thin and improve the simple back design of the display device, the at least one module receiving portion 370 may be provided only in the first back cover 310 and not in the second back cover 350, so that it may not be exposed to the outside of the back cover 300. The at least one module receiving portion 370 may not completely pass through the back cover 300 and may therefore be referred to as a module receiving groove. The at least one module receiving portion 370 may be referred to as a module insertion portion, a module insertion groove, a module receiving portion, a module receiving groove, or a groove, but the term is not limited thereto.

[0434] According to some embodiments of the present disclosure, the back 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 or disposed.

[0435] According to some embodiments of the present disclosure, each of the two module receiving portions 370 may have a size capable of accommodating the corresponding sound generating module 500 therein. Furthermore, each of the two module receiving portions 370 may have a height (or depth) that is smaller than the total height of the sound generating module 500. Each of the two module receiving portions 370 may be disposed so as to pass through the first back cover 310, and thus, the thickness (or depth) of the first back cover 310 is smaller than the total height of the sound generating module 500. When the thickness of the first back cover 310 is greater than the total height of the sound generating module 500, the height of the gap space GS provided between the display module 100 and the back cover 300 may be insufficient. Consequently, due to physical contact between the first back cover 310 and the display module 100 vibrating based on the driving of the vibration device 530, the desired sound may not be generated, or noise such as frictional sound may occur. Therefore, the thickness of the first back cover 310 or the height (or depth) of the module receiving portion 370 may be set within a range that prevents physical contact between the first back cover 310 and the display module 100 vibrating based on the driving of the vibration device 530.

[0436] According to some embodiments of the present disclosure, in addition to the at least one sound generating module 500 being provided on the rear surface of the display module 100 and being provided at the second rear cover 350 exposed by the module receiving portion 370 by using the first member 410 (or module fixing member), the at least one sound generating module 500 is provided with a plurality of Figures 2 to 5B The sound generating modules shown are the same, so their repeated description is omitted.

[0437] According to another embodiment of the present disclosure, the back cover 300 may include a module receiving portion 370 in which the module is received and arranged. Figure 8 and Figure 9 One sound generating module 500 is shown. Even for example, one module receiving portion 370 may be provided to vertically pass through the first rear cover 310 of the rear cover 300 in the thickness direction Z and may be covered by the second rear cover 350 .

[0438] Therefore, in the display device according to another embodiment of the present disclosure, since at least one sound generating module 500 is accommodated and disposed in the module receiving portion 370 in the back cover 300, the thickness can be reduced by the height (or depth) of the module receiving portion 370, and the weight can be reduced by the size of the module receiving portion 370. In the display device according to another embodiment of the present disclosure, since the sound generating module 500 is accommodated and disposed in the module receiving portion 370 in the back cover 300, the assembly process between the sound generating module 500 and the back cover 300 can be simplified.

[0439] As another example, the back cover 300 may include a plurality of holes 300 h overlapping with at least one module receiving part 370 .

[0440] Each of the plurality of holes 300h may be provided to vertically penetrate the second rear cover 350 of the rear cover 300 in the thickness direction Z and may be connected to (or communicated 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 the at least one module receiving portion 370. Figure 7 The description can be identically applied to the shape and size of each of the plurality of holes 300h, and thus, repeated description is omitted.

[0441] Figure 12 A display device according to another embodiment of the present disclosure is shown. Figure 13 It is along Figure 12 The cross-sectional view is taken along line II-II'.

[0442] Figure 12 and Figure 13 Shown in Figure 10 and Figure 11 The embodiment of the structure of the sound generating module is modified in the display device shown in FIG. Therefore, hereinafter, repeated description of elements other than the sound generating module will be briefly given or omitted.

[0443] Reference Figure 12 and Figure 13, a display device according to another embodiment of the present disclosure may include at least one sound generating module 500, which is disposed between the display module 100 and the back cover 300 to vibrate the display module 100, and the at least one sound generating module 500 may be accommodated and disposed in at least one module accommodating portion 370 provided in the back cover 300.

[0444] At least one module receiving portion 370 in the rear cover 300 is connected to Figure 10 and Figure 11 The module accommodating portions shown are the same, and therefore, repeated descriptions thereof are omitted.

[0445] At least one sound generating module 500 may be accommodated and disposed in at least one module receiving portion 370 provided in the back cover 300 while being modularized as one element. The at least one sound generating module 500 according to some embodiments of the present disclosure may be accommodated in at least one module receiving portion 370 provided in the first back cover 310 of the back cover 300 and may be supported by the front surface of the first back cover 310. For example, the at least one sound generating module 500 may have a box structure with one side open and including a border. The at least one sound generating module 500 may directly vibrate the display module 100 to generate sound PVS based on the vibration of the display module 100 (e.g., the display panel 110).

[0446] According to an embodiment of the present disclosure, the rear center portion of the sound generating module 500 may pass through the module receiving portion 370 and may be disposed on or fixed to the second rear cover 350 by using the first member 410 (or module fixing member). The edge portion or boundary portion of the sound generating module 500 may be supported by (or stably placed on) the front surface of the first rear cover 310 and may be disposed on or coupled to the display module 100 (e.g., the rear surface of the display panel 110) by using the connecting member 550, or may be disposed on or coupled to the rear surface of the heat dissipation member 150 disposed on the rearmost surface of the display module 100 by using the connecting member 550.

[0447] According to another embodiment of the present disclosure, the sound generating module 500 may be provided on or fixed to the second rear cover 350 by a plurality of screws. For example, an edge portion or a boundary portion of the sound generating module 500 may be provided on 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 edge portion of the sound generating module 500 and the connecting member 550, and may be provided on or fastened to the first rear cover 310.

[0448] According to another embodiment of the present disclosure, the sound generating module 500 may be provided on or fixed to the second rear cover 350 by means of a bolt and a nut. The nut may be provided on or fixed to the front surface of the first rear cover 310 that overlaps with the edge portion of the sound generating module 500. The bolt may pass through the edge portion of the sound generating module 500 and the connecting member 550 and may be fastened to the nut. The nut according to an embodiment of the present disclosure may be a self-tightening nut fixed to the front surface of the first rear cover 310.

[0449] Therefore, in the display device according to another embodiment of the present disclosure, since at least one sound generating module 500 is accommodated and disposed in the module receiving portion 370 provided in the back cover 300, the thickness can be reduced by the height (or depth) of the module receiving portion 370, and the weight can be reduced by the size of the module receiving portion 370. In the display device according to another embodiment of the present disclosure, since the sound generating module 500 is accommodated and disposed in the module receiving portion 370 provided in the back cover 300, the assembly process between the sound generating module 500 and the back cover 300 can be simplified.

[0450] Figure 14 Shown Figure 12 and Figure 13 The sound generation module shown. Figure 15 Shown Figure 14 The module structure shown.

[0451] Reference Figures 12 to 15 , a sound generating module 500 according to another embodiment of the present disclosure may include a module structure 2510 , a vibration device 530 , a connection member 550 , and a module adhesive member 450 .

[0452] The module structure 2510 may be received and disposed in the module receiving portion 370 in the rear cover 300, and may fix (or support) the vibration device 530. According to some embodiments of the present disclosure, the module structure 2510 may include a forming-enabled metal material.

[0453] The module structure 2510 according to some embodiments of the present disclosure may include an edge portion 511 (also referred to as a boundary portion), a bottom portion 513, and an inclined portion 515. The edge portion 511, the bottom portion 513, and the inclined portion 515 may be referred to as a first portion, a second portion, and a third portion, respectively, but these terms are not limited thereto.

[0454] The edge portion 511 may have a square (e.g., quadrilateral) strip shape and may be supported by (or stably placed on) the front surface of the rear cover 300 (e.g., the first rear cover 310) adjacent to the module receiving portion 370. For example, the edge portion 511 may be an edge portion (or edge portion, or peripheral portion, or boundary portion) of a metal plate serving as a base member for forming the module structure 2510.

[0455] The bottom portion 513 may be disposed on or fixed to the second back cover 350 of the back cover 300 exposed by the module receiving portion 370. For example, the bottom portion 513 may pass through the module receiving portion 370 and may be disposed on or fixed to the second back cover 350 by using the first member 410 (or module fixing member).

[0456] The inclined portion 515 can be provided to be inclined between the edge portion 511 and the bottom portion 513, thereby defining a receiving space on the bottom portion 513. For example, the bottom portion 513 and the inclined portion 515 can have a structure such that a portion of the metal plate other than the edge portion protrudes toward the rear cover 300 by using a molding process. The bottom portion 513 and the inclined portion 515 can be referred to as a receiving portion, a formed portion, or a pocket portion for receiving the vibration device 530, but these terms are not limited thereto.

[0457] According to some embodiments of the present disclosure, 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 rim portion 511 may be equal to or less than the height of the first back cover 310. When the height H of the inclined portion 515 is greater than the height of the first back cover 310, the rim portion 511 may not be stably supported by the front surface of the first back cover 310, and a portion of the inclined portion 515 and the rim portion 511 may protrude upward from the front surface of the first back cover 310, causing a problem in which a portion of the inclined portion 515 and the rim portion 511 vibrate based on the 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 rim portion 511 may be equal to or less than the height of the first back cover 310, so that the rim portion 511 is stably supported to (or stably placed on) the front surface of the first back cover 310.

[0458] The vibration device 530 can be accommodated in the receiving space of the module structure 2510. The vibration device 530 according to some embodiments of the present disclosure can be provided on or fixed to the bottom 513 of the module structure 2510 and can vibrate the display module 100 (e.g., the display panel 110). By using the module integration member 520, the vibration device 530 can be provided on or fixed to the module structure 2510, or can be provided integrally with the module structure 2510, so that the vibration device 530 and the module structure 2510 can be modularized into one element.

[0459] The vibration device 530 according to some embodiments of the present disclosure may include any sound device or vibration generating device for vibrating the display module 100 based on an electrical signal. According to some embodiments of the present disclosure, the vibration device 530 may include an actuator (or exciter) disposed 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, a frame 536, and a damper 537. These elements are connected to the vibration device 530. Figures 2 to 5B The elements of the vibration device shown are the same, so their repeated description is omitted.

[0460] The uppermost surface of the vibration device 530 according to some embodiments of the present disclosure can be disposed on the same uppermost surface extension line HL (or horizontal line) as the edge portion 511 of the module structure 2510, or can protrude upward from the uppermost surface extension line HL of the edge portion 511. For example, when the uppermost surface of the vibration device 530 is disposed below the uppermost surface extension line HL of the edge portion 511 and is completely received in the receiving space of the module structure 2510, it may be difficult to couple or connect the vibration device 530 to the rear surface of the display module 100. Therefore, by using only a simple module arrangement process, the uppermost surface of the vibration device 530 can protrude upward from the uppermost surface extension line HL of the edge portion 511 for coupling or connecting the vibration device 530 to the rear surface of the display module 100.

[0461] The connecting member 550 may be disposed between the edge portion 511 of the module structure 2510 and the rear surface of the display module 100 , and thus a gap space GS may be provided between the rear surface of the display module 100 and the back cover 300 , and the module structure 2510 may be disposed on or connected to the rear surface of the display module 100 .

[0462] According to some embodiments of the present disclosure, one surface (or front surface) of the connection member 550 may be disposed on or coupled to the rear surface of the heat dissipation member 150 coupled to the display module 100 (e.g., the display panel 110 or the rear surface of the display panel 110), and the other surface (or rear surface) of the connection member 550 may be disposed on or coupled to the edge portion 511 of the module structure 2510. For example, the connection member 550 may be a double-sided tape or a double-sided foam tape, but is not limited thereto. The connection member 550 may provide a vibration space surrounding the vibration device 530 between the module structure 2510 and the display module 100.

[0463] The module adhesive member 450 may be a double-sided adhesive member between the display module 100 and the vibration device 530. The double-sided adhesive member may be, but is not limited to, a double-sided tape or double-sided foam tape. One surface (or front surface) of the module adhesive member 450 may be disposed on or coupled to the rear surface of the heat dissipation member 150 disposed in the display module 100 (e.g., the display panel 110 or the rear surface of the display panel 110), and the other surface (or rear surface) of the module adhesive member 450 may be disposed on or coupled to the bobbin 534 or bobbin protection member 538 of the vibration device 530.

[0464] As another example, the heat dissipation member 150 coupled to or provided on the rear surface of the display panel 110 may be provided integrally with the sound generating module 500. For example, the heat dissipation member 150 may be coupled to or provided on each of the connection 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. Thus, in a transfer process after performing a modularization process on the sound generating module 500 modularized into one element, the vibration device 530 and each of the connection member 550 and the module adhesive member 450 of the sound generating module 500 may be prevented from being exposed to the outside, and particles such as dust may be prevented from penetrating into the sound generating module 500.

[0465] The sound generating module 500 according to another embodiment of the present disclosure may include: a groove provided in the bottom 513 of the module structure 2510 to overlap with the vibration device 530; a hollow portion passing through each of the bottom plate 531, the magnet 532, and the center pole 533 of the vibration device 530 in the vertical direction Z to overlap with the groove; and at least one of the plurality of plate holes provided in the bottom plate 531 to overlap with each of the magnet 532 and the bobbin 534 of the vibration device 530. For example, each of the groove, the hollow portion, and the plurality of plate holes may substantially and respectively correspond to Figure 6 The groove 510h and the hollow portion 530h and each of the plurality of plate holes 531h of the sound generating module 500 are shown, and therefore, their repeated description is omitted. Figure 6 Each of the groove 510h and the hollow portion 530h and the plurality of plate holes 531h of the illustrated sound generating module 500 may be identically or similarly applied to Figure 14 Corresponding elements of the sound generating module are shown.

[0466] Figure 16A A rear surface of a module structure of a sound generating module according to an embodiment of the present disclosure is shown. Figure 16B A voice signal cable and a vibration device provided in a module structure of a sound generating module according to an embodiment of the present disclosure are shown.

[0467] Reference Figure 16A and Figure 16B , the module structure 2510 according to an embodiment of the present disclosure may include a groove 510h and a plurality of cable holes 517 (or cable through-holes).

[0468] The groove 510h may be provided to pass through the bottom 513 of the module structure 2510 in the vertical direction Z to overlap with the vibration device 530. The groove 510h may accommodate a portion of the rear surface of the vibration device 530. For example, the groove 510h may have a square (e.g., quadrilateral) shape corresponding to the bottom plate 531 of the vibration device 530, but is not limited thereto. For example, the groove 510h may have a circular or oval shape.

[0469] The groove 510 h according to some embodiments of the present disclosure may expose the line terminals 530 p and 530 m of the vibration device 530 at the rear surface of the module structure 2510 .

[0470] Each of the plurality of cable holes 517 can extend from a corresponding corner of the groove 510h to have a specific size and shape and can communicate with the corresponding corner of the groove 510h. For example, each of the plurality of cable holes 517 can be a path through which a voice signal cable 590 electrically connected to the line terminals 530p and 530m of the vibration device 530 exposed at the groove 510h is discharged to the receiving space of the module structure 2510. Therefore, the voice signal cable 590 can be electrically connected to the line terminals 530p and 530m of the vibration device 530 exposed at the groove 510h, and then can be discharged to the receiving space of the module structure 2510 through the corresponding cable hole 517. The voice signal cable 590 discharged to the receiving space of the module structure 2510 can then be discharged to the outside of the module structure 2510 via the bottom 513, the inclined portion 515, and the edge portion 511 of the module structure 2510.

[0471] The module structure 2510 according to an embodiment of the present disclosure can accommodate the voice signal cable 590 connected to the line terminals 530p and 530m of the vibration device 530, and therefore, defects such as disconnection of the voice signal cable 590 can be prevented in the transfer processing after the modularization processing is performed on the sound generating module 500 modularized into one element.

[0472] Figure 17 A rear surface of a rear cover according to an embodiment of the present disclosure is shown.

[0473] Figure 17 This is a diagram for describing the arrangement structure of a voice signal cable through which a voice signal is applied to a sound generating module.

[0474] Reference Figure 12 and Figure 17, the voice signal cable 590 according to an embodiment of the present disclosure may be provided between the display module 100 and the sound generating module 500 , and may be discharged to the outside through a cable discharge hole 390 provided in the back cover 300 .

[0475] According to some embodiments of the present disclosure, one end or a portion of the voice signal cable 590 may be electrically connected to a line terminal provided in the corresponding sound generating module 500. For example, one end or a portion of the voice signal cable 590 may be electrically connected to the line terminal provided in the corresponding sound generating module 500 by welding.

[0476] According to some embodiments of the present disclosure, the other end or another portion of the voice signal cable 590 can be discharged to the outside of the receiving space of the corresponding sound generating module 500 via the receiving space of the corresponding sound generating module 500 and the space between the display module 100 and the sound generating module 500, and then, can pass through the cable discharge hole 390 via the space between the display module 100 and the back cover 300, and can be discharged to the outside of the display device. Figure 17 , a portion of the voice signal cable 590 indicated by a dotted line may be covered by the rear cover 300 and thus may not be visible from the rear surface of the rear cover 300, and another portion of the voice signal cable 590 indicated by a thick solid line may be discharged to the outside of the display device via the cable discharge hole 390 and thus may be visible from the rear surface of the rear cover 300. In addition, the voice signal cable 590 discharged through the cable discharge hole 390 may be covered by a circuit cover or a cover covering the circuit unit of the display device.

[0477] Therefore, since the voice signal cable 590 and the sound generating module 500 are covered by the rear cover 300 , the display device according to an embodiment of the present disclosure may have its simple rear design.

[0478] Figure 18 A display device according to another embodiment of the present disclosure is shown. Figure 19 It is along Figure 18 The cross-sectional view is taken along line III-III'. Figure 20 It is along Figure 18 Another cross-sectional view taken along line III-III' is shown. Figure 21 It is along Figure 18 Another cross-sectional view taken along line III-III' is shown.

[0479] Figure 18 and Figure 19 Shown based on Figures 12 to 17The display device shown is an embodiment in which the structure of the rear cover according to the embodiment of the present disclosure is modified. Therefore, hereinafter, except for the rear cover and its related elements, descriptions of the same elements will be briefly given or omitted.

[0480] First, in Figures 12 to 17 In the display device shown, the back cover 300 may include a plurality of module accommodating portions 370, into which the sound generating module 500 modularized as one element is accommodated or inserted. In a display device having only one sound generating module 500 based on the finished structure of the display device, a back cover 300 including only one module accommodating portion 370 may be used. In addition, in a display device having no sound generating module 500 based on the finished structure of the display device, a back cover 300 without a module accommodating portion 370 may be used. It may cost a lot to manufacture a back cover corresponding to each finished structure of the display device, and therefore, the manufacturing cost of the display device may increase. In order to solve such a problem, the display device according to an embodiment of the present disclosure may include such a back cover: regardless of the final product structure, the back cover is universal. For example, regardless of whether it is a display device that does not include the sound generating module 500 or a display device that includes the sound generating module 500, the display device according to an embodiment of the present disclosure can include a universal back cover, and therefore, the cost (for example, molding cost) of manufacturing the back cover based on the finished product structure of the display device can be reduced, and by modularizing the sound generating module, the freedom of whether the finished product is to be provided with or not provided with the sound generating module can be increased.

[0481] Reference Figure 18 and Figure 19 , a display apparatus according to another embodiment of the present disclosure may include first to third sound generating modules 500 - 1 to 500 - 3 provided between the display module 100 and the back cover 1300 .

[0482] The display module 100 and Figure 2 and Figure 3A-Figure 3E The display modules shown are the same, so repeated descriptions thereof are omitted.

[0483] The back cover 1300 may be a universal back cover and may include a plurality of module receiving portions 370a to 370c. Each of the plurality of module receiving portions 370 may be disposed so as to penetrate the first back cover 310 of the back cover 1300 in the vertical direction Z. For example, the back cover 1300 may include a first module receiving portion 370a overlapping with a first region (or left region) of the display module 100, a second module receiving portion 370b overlapping with a second region (or right region) of the display module 100, and a third module receiving portion 370c overlapping with a third region (or central region) of the display module 100 located between the first and second regions.

[0484] The first sound generating module 500-1, the second sound generating module 500-2, and the third sound generating module 500-3 may be accommodated and disposed in the plurality of module accommodating portions 370a, 370b, and 370c, respectively, and may respectively and individually vibrate the first to third areas of the display module 100 (e.g., the display panel 110). Each of the first sound generating module 500-1, the second sound generating module 500-2, and the third sound generating module 500-3 may be separately and individually vibrated. Figure 3A-Figure 3E 、 Figure 6 、 Figure 10 and Figures 14 to 16B The sound generating modules shown are the same, and therefore, their repeated descriptions are omitted.

[0485] Therefore, a display device according to another embodiment of the present disclosure can output three-channel stereo based on left sound LS, right sound RS and center sound CS according to the vibration of the display module 100 (e.g., display panel 110) driven by each of the first sound generating module 500-1, the second sound generating module 500-2 and the third sound generating module 500-3.

[0486] As another example, a display device according to another embodiment of the present disclosure may include some of the first sound generating module 500-1, the second sound generating module 500-2, and the third sound generating module 500-3 based on the finished product structure. For example, a display device according to another embodiment of the present disclosure may not include the third sound generating module 500-3 among the first sound generating module 500-1, the second sound generating module 500-2, and the third sound generating module 500-3, and may include the first sound generating module 500-1 and the second sound generating module 500-2. For example, Figure 18 and Figure 20 As shown, each of the first sound generating module 500-1 and the second sound generating module 500-2 including the vibration device 530 can be respectively accommodated and set in the first module accommodating portion 370a and the second module accommodating portion 370b set in the back cover 1300, and can respectively and individually vibrate the first area and the second area of ​​the display module 100 (for example, the display panel 110), thereby outputting two-channel stereo based on the left sound LS and the right sound RS based on the vibration of each of the first area and the second area of ​​the display panel 110.

[0487] Furthermore, in the display device according to another embodiment of the present disclosure, since the third sound generating module 500-3 is not accommodated or inserted into the third module accommodating portion 370c provided in the rear cover 1300, and the third module accommodating portion 370c is open, a problem may arise due to a change in sound pressure caused by the overlap of the gap space between the rear cover 1300 and the display module 100 with the third module accommodating portion 370c, and the heat dissipation characteristics of the display module 100 overlapping with the third module accommodating portion 370c may be reduced. In order to solve these problems, the display device according to another embodiment of the present disclosure may further include a cover body 900, such as Figure 20 shown.

[0488] The cover 900 may be a covering structure for covering a module receiving portion in which the third sound generating module 500-3 is not inserted (or received). The cover 900 according to some embodiments of the present disclosure may be configured to have a structure substantially identical to the module structure 2510 of each of the sound generating modules 500-1, 500-2, and 500-3, and unlike the sound generating modules 500-1, 500-2, and 500-3, the cover 900 may not include a vibration device. For example, the cover 900 may include Figure 15 The edge portion 511, the bottom portion 513 and the inclined portion 515 of the module structure 2510 shown. For example, the rear surface of the cover 900 can be set on or fixed to the second rear cover 350 exposed by the third module accommodating portion 370c by using a first member 910 (or a cover fixing member). In addition, the front surface of the cover 900 can be connected to the rear surface of the display module 100 by using a cover adhesive member 920. Therefore, the cover 900 can cover the third module accommodating portion 370c that does not accommodate the third sound generating module 500-3, thereby solving the problem caused by the opening of the third module accommodating portion 370c. The cover 900 can be referred to as a hole cover, a cap or a cover, but the term is not limited thereto.

[0489] As another example, a display device according to another embodiment of the present disclosure may not include all of the first sound generating module 500-1, the second sound generating module 500-2, and the third sound generating module 500-3 based on the finished product structure. Figure 18 and Figure 21As shown, in a display device according to another embodiment of the present disclosure, the first sound generating module 500-1, the second sound generating module 500-2, and the third sound generating module 500-3 may not be accommodated in the first module accommodating portion 370a, the second module accommodating portion 370b, and the third module accommodating portion 370c provided in the rear cover 1300, and the first module accommodating portion 370a, the second module accommodating portion 370b, and the third module accommodating portion 370c may be open, thereby causing a decrease in heat dissipation characteristics in the display module 100 overlapping with the first module accommodating portion 370a, the second module accommodating portion 370b, and the third module accommodating portion 370c. To solve such a problem, the display device according to another embodiment of the present disclosure may further include a first cover 900-1, a second cover 900-2, and a third cover 900-3, which are accommodated and provided in the first module accommodating portion 370a, the second module accommodating portion 370b, and the third module accommodating portion 370c, respectively.

[0490] Each of the first cover 900-1, the second cover 900-2, and the third cover 900-3 can be configured to have a structure substantially the same as the module structure 2510 of the first sound generating module 500-1, the second sound generating module 500-2, and the third sound generating module 500-3, and unlike the first sound generating module 500-1, the second sound generating module 500-2, and the third sound generating module 500-3, each of the first cover 900-1, the second cover 900-2, and the third cover 900-3 can not include a vibration device. For example, each of the first cover 900-1, the second cover 900-2, and the third cover 900-3 can be disposed on or fixed to the second back cover 350 exposed by each of the first module accommodating portion 370a, the second module accommodating portion 370b, and the third module accommodating portion 370c using the first member 910 (or cover fixing member). In addition, the front surface of each of the first cover 900-1, the second cover 900-2, and the third cover 900-3 may be provided on or coupled to the rear surface of the display module 100 by using the cover adhesive member 920. Therefore, the first cover 900-1, the second cover 900-2, and the third cover 900-3 may respectively cover the first module accommodating portion 370a, the second module accommodating portion 370b, and the third module accommodating portion 370c in which the first sound generating module 500-1, the second sound generating module 500-2, and the third sound generating module 500-3 are not accommodated or inserted, thereby solving a problem that occurs due to each of the first module accommodating portion 370a, the second module accommodating portion 370b, and the third module accommodating portion 370c being open. Therefore, the back cover 1300 can include a plurality of module accommodating portions 370a, 370b and 370c, and the plurality of module accommodating portions 370a, 370b and 370c are selectively equipped with a first sound generating module 500-1, a second sound generating module 500-2 and a third sound generating module 500-3 and a cover body 900, so that the back cover 1300 can be universal regardless of the finished structure of the display device.

[0491] Figure 22 A display device according to another embodiment of the present disclosure is shown.

[0492] Reference Figure 22 , a display device according to another embodiment of the present disclosure may include at least one sound generating module 500 provided on the rear surface of the back cover 300. The at least one sound generating module 500 may be accommodated and disposed in at least one module accommodating portion 370 provided in the back cover 300. The at least one sound generating module 500 may be attached to the back cover 300.

[0493] At least one module receiving portion 370 provided in the rear cover 300 is Figure 10 and Figure 11The module accommodating parts shown in FIG. 1 are the same, so repeated description thereof is omitted.

[0494] At least one sound generating module 500 may be housed and disposed in at least one module receiving portion 370 disposed in the back cover 300 and modularized into one element. At least one sound generating module 500 according to some embodiments of the present disclosure may be housed in at least one module receiving portion 370 disposed in the first back cover 310 of the back cover 300 and may be supported by the rear surface of the first back cover 310. For example, at least one sound generating module 500 may have a box structure with one side open and including an edge or boundary. At least one sound generating module 500 may indirectly vibrate the display module 100 to generate sound PVS based on the vibration of the display module 100 (e.g., the display panel 110).

[0495] Therefore, in the display device according to another embodiment of the present disclosure, since at least one sound generating module 500 is accommodated and disposed in the module receiving portion 370 provided in the back cover 300, the thickness can be reduced by the height (or depth) of the module receiving portion 370, and the weight can be reduced by the size of the module receiving portion 370. In the display device according to another embodiment of the present disclosure, since the sound generating module 500 is disposed on the rear surface of the back cover 300, the assembly process between the sound generating module 500 and the back cover 300 can be simplified.

[0496] 23A to 23D A panel according to another embodiment of the present disclosure is shown.

[0497] Reference 23A to 23D , the plate can be used as a vibrating plate to produce sound.

[0498] For example, Figure 23A The glass plate 601 may include a glass material, and the glass plate 601 may be implemented as a sound plate, wherein Figure 3A-Figure 3E 、 Figure 5A and Figure 5B 、 Figure 6 and Figures 14 to 16B The sound generating module is provided on the rear surface of the glass plate 601 to output the sound. Figures 24A to 46B The described sound generating module or sound generating device can be provided on the rear surface of the glass plate 601. For example, the glass plate 601 can be provided as a photo frame type. The sound generating module can be provided on the rear surface of a photo frame including a photo or picture, so that the user can hear the sound while looking at or viewing the photo or picture.

[0499] As another example, Figure 23BThe wooden board 602 may be a wooden board 602 including a wood material, and the wooden board 602 may be implemented as a sound board. For example, the wooden board 602 may be implemented as a sound board, wherein Figure 3A-Figure 3E 、 Figure 5A and Figure 5B 、 Figure 6 and Figures 14 to 16B The sound generating module is provided on the rear surface of the wooden board 602 to output the sound. Figures 24A to 46B The described sound generating module or sound generating device may be provided on the rear surface of the wooden board 602 .

[0500] As another example, Figure 23C The plastic plate 603 may be a plastic material, and the plastic plate 603 may be implemented as a soundboard. For example, the plastic plate 603 may be implemented as a soundboard, wherein Figure 3A-Figure 3E 、 Figure 5A and Figure 5B 、 Figure 6 and Figures 14 to 16B The sound generating module is provided on the rear surface of the plastic plate 603 to output the sound. Figures 24A to 46B The described sound generating module or sound generating device may be provided on the rear surface of the plastic plate 603 .

[0501] As another example, Figure 23D The metal plate 604 may be a metal material, and the metal plate 604 may be implemented as a sound board. The metal plate 604 may be a metal injection material. For example, the metal plate 604 may be implemented as a sound board, wherein Figure 3A-Figure 3E 、 Figure 5A and Figure 5B 、 Figure 6 and Figures 14 to 16B The sound generating module is provided on the rear surface of the metal plate 604 to output the sound. Figures 24A to 46B The described sound generating module or sound generating device may be provided on the rear surface of the metal plate 604 .

[0502] As another example, Figure 3A-Figure 3E 、 Figure 5A and Figure 5B 、 Figure 6 and Figures 14 to 16B The sound generation module can be set in the projection screen or image reproduction device to output sound, thereby providing stereo sound to the user. As another example, Figure 3A-Figure 3E 、 Figure 5A and Figure 5B 、 Figure 6 and Figures 14 to 16B The sound generation module may be provided in a device such as a Bluetooth device to output sound, thereby providing sound to a user.

[0503] As another example, when the following reference is made to Figures 24A to 32E The multi-channel sound generation module described is arranged in 23A to 23D In the embodiment of the present invention and in a projection screen, an image reproduction device or a Bluetooth device, stereo and realistic stereophonic sound or surround sound can be provided to the user.

[0504] As another example, when the following reference is made to Figures 33 to 44C The described thin film type or piezoelectric composite sound generating module is arranged in 23A to 23D In the embodiment and in a projection screen, an image reproduction device or a Bluetooth device, a vibration device with a thin thickness can be configured, and stereo sound or surround sound with a sense of reality can be provided to the user.

[0505] Therefore, according to another embodiment of the present disclosure, due to the application of the sound board and the modular sound generation module, images and stereo sounds can be provided, thereby enhancing the user's immersive experience and providing stereo sound or surround sound with a sense of reality.

[0506] When referring to the above Figures 1 to 23D When the described sound generating module is applied to a display device, the sound generating module can be set in at least two of the three areas. For example, the sound generating module can be set in the left area and the right area of ​​the display device, and the left sound and the right sound can be output to the front area in front of the display panel. For example, the inventor has realized that the sound of the display panel in the left and right directions is output, but the sound of the display panel in the up and down directions is not output. Multiple sound generating modules can be set to enhance the sound of the display panel in the up and down directions, but when multiple sound generating modules are set, the problem of thickening the thickness of the display device may arise. In addition, in order to output stereo sound, additional speakers can be set near the display device. Since the speaker should need to control the distance to the user based on the desired frequency, there may be a problem that the speaker should be set based on the user position or the image position. Therefore, the inventor has conducted various experiments to realize such a sound generating module, wherein the thickness of the display device is not thickened, and the left sound, right sound, top sound (height sound) and bottom sound are realized based on the image. Through various experiments, the inventor has invented a display device, which includes a sound generating module with a new structure, which realizes the left sound, right sound, top sound and bottom sound. This will be described below with reference to Figures 24A to 44C Provide a description.

For example, the second area 2 and the fifth area 5 may be the right area of ​​the rear surface of the display panel 110. For example, the third area 3 may be the central area of ​​the rear surface of the display panel 110. As another example, when the sound generating module is as described above with reference to Figure 2 When the device is provided on the rear surface of the rear cover 300, the first area 1 to the fifth area 5 may be areas of the rear surface of the rear cover 300. The descriptions related thereto may be applied identically or similarly to the device.

The third sound generating module 1500C may be the center channel of the display panel 110.

[0512] The first integrated woofer sound generating module W1 and the second integrated woofer sound generating module W2 can each be a sound generating module configured as a whole with a woofer, so a separate woofer may not be provided. The first integrated woofer sound generating module W1 and the second integrated woofer sound generating module W2 can each be a sound generating module including a woofer. Figure 25A and Figure 25B A first woofer-integrated sound generating module W1 and a second woofer-integrated sound generating module W2 are described.

[0513] The first and second woofer-integrated sound generating modules W1 and W2 can output sounds of about 60 Hz to about 40 kHz, and the third, fourth, and fifth sound generating modules 1500C, 1500HL, and 1500HR can output sounds of about 80 Hz to about 40 kHz. Therefore, the display device can output 3.2-channel sound.

[0514] Compared to the sound generation modules on the left and right sides of the display panel, since the sound generation modules are further arranged at the top and bottom of the display panel, the left and right sounds, as well as the top and bottom sounds, can be enhanced, allowing the user to experience a sound field that feels like real sound. For example, due to the additional arrangement of the fourth sound generation module 1500HL and the fifth sound generation module 1500HR, sound can be output from the top of the display panel 110, thereby providing a display device that implements stereo sound including left and right sounds, as well as top and bottom sounds. Thus, left and right sounds corresponding to the left and right images, as well as top and bottom sounds corresponding to the top and bottom images, can be implemented. Furthermore, true stereo sound including stereo left and right sounds, as well as stereo top and bottom sounds, can be implemented, providing the user with real sound rather than virtual sound. Thus, true stereo or surround sound including stereo left and right sounds, as well as stereo top and bottom sounds, can be provided to the user, enhancing the sense of reality. Therefore, in theaters, private cinemas, and devices such as televisions, users can simultaneously experience real sounds and images that are similar to or the same as reality, and can experience, for example, a real audio-visual (AV) or Dolby sound system.

[0515] In addition, when 23A to 23D Implemented in the soundboard Figure 24A and Figure 24B When the multi-channel sound generation module is provided, a real stereo or surround sound including real sounds of stereo left and right sounds and stereo top and bottom sounds can be provided to the user, thereby enhancing the sense of reality. 23A to 23D Set in the soundboard Figure 24A and Figure 24B When the multi-channel sound generation module and the projection or image reproduction device are provided, a real AV or Dolby sound system can be provided so that the user can simultaneously feel the real sound and image similar to or the same as the reality. In addition, stereo sound can be provided to provide the user with an immersive experience and a sense of reality. Figures 1 to 22 As described above, a modular sound generating module can be applied. Therefore, when the sound generating module is provided, the degree of freedom in designing the display device or the back cover can be improved.

[0516] For example, the fourth sound generating module 1500HL and the fifth sound generating module 1500HR may be arranged symmetrically, but the present disclosure is not limited to this. For example, the fourth sound generating module 1500HL and the fifth sound generating module 1500HR may be arranged on the same line, but the present disclosure is not limited to this. For example, the sound generating module W1 of the first integrated woofer may be arranged symmetrically with the sound generating module W2 of the second integrated woofer, but the present disclosure is not limited to this. For example, the sound generating module W1 of the first integrated woofer and the sound generating module W2 of the second integrated woofer may be arranged on the same line, but the present disclosure is not limited to this. For example, the sound generating module W1 of the first integrated woofer and the sound generating module W2 of the second integrated woofer may be arranged symmetrically with the third sound generating module 1500C, but the present disclosure is not limited to this. For example, the sound generating module W1 of the first integrated woofer and the sound generating module W2 of the second integrated woofer may be arranged on the same line with the third sound generating module 1500C, but the present disclosure is not limited to this.

[0517] Reference Figure 24B The first and second integrated woofer sound generating modules W1 and W2 may be arranged asymmetrically with respect to the third sound generating module 1500C, but the embodiments of the present disclosure are not limited thereto. For example, the first and second integrated woofer sound generating modules W1 and W2 may be arranged on different lines from the third sound generating module 1500C, but the embodiments of the present disclosure are not limited thereto. For example, the first integrated woofer sound generating module W1 may be separated from the fourth sound generating module 1500HL arranged in the fourth area 4. Therefore, the sound of the lower portion of the display panel 110 may be more vividly realized in the first integrated woofer sound generating module W1, and based on the distance between the first integrated woofer sound generating module W1 and the fourth sound generating module 1500HL, a sound for distinguishing the difference between the sound of the first integrated woofer sound generating module W1 and the sound of the fourth sound generating module 1500HL may be realized. In addition, the sound generating module W2 of the second integrated woofer can be separated from the fifth sound generating module 1500HR set in the fifth area 5, so that the sound of the lower part of the display panel 110 can be more vividly realized in the sound generating module W2 of the second integrated woofer, and based on the distance between the sound generating module W2 of the second integrated woofer and the fifth sound generating module 1500HR, a sound for distinguishing the difference between the sound of the second integrated woofer sound generating module W2 and the sound of the fifth sound generating module 1500HR can be realized.

[0518] Reference Figure 24A and Figure 24B The sound generating module W1 of the first integrated woofer can be configured asymmetrically with the fourth sound generating module 1500HL. The sound generating module W2 of the second integrated woofer can be configured asymmetrically with the fifth sound generating module 1500HR. For example, this can reduce constructive or destructive sound interference caused by vibration interference between the vibrations and standing waves generated by the sound generating module W1 of the first integrated woofer and the vibrations and standing waves generated by the fourth sound generating module 1500HL. Undesirable constructive or destructive sound interference caused by external interference other than the vibrations of the reproduced sound source can cause sound distortion and thus reduce sound quality. The asymmetrical structure between the sound generating module W1 of the first integrated woofer and the fourth sound generating module 1500HL can prevent undesirable interference, thereby reproducing natural sound similar to the original sound. This can also reduce constructive or destructive sound interference caused by vibration interference between the vibrations and standing waves generated by the sound generating module W2 of the second integrated woofer and the vibrations and standing waves generated by the fifth sound generating module 1500HR. In addition to the vibrations based on the reproduced sound source, unwanted constructive or destructive interference of sounds caused by external interference can cause sound distortion, thereby reducing sound quality. The asymmetric structure between the sound generating module W2 of the second integrated woofer and the fifth sound generating module 1500HR can prevent unwanted interference, thereby reproducing natural sound similar to the original sound. As another example, the sound generating module W1 of the first integrated woofer can be arranged to be symmetrical with the fourth sound generating module 1500HL. The sound generating module W2 of the second integrated woofer can be arranged to be symmetrical with the fifth sound generating module 1500HR. For example, the sound reproduction positions can be aligned on the same line, thereby achieving an effect such as reproducing the sound at the same position compared to an asymmetric structure. Therefore, the sense of recognition of the sound position can be enhanced, thereby enhancing the localization of the sound.

[0519] As another example, at least one of the fourth sound generating module 1500HL and the fifth sound generating module 1500HR can be configured to include a sound generating module of a woofer. For example, the first sound generating module W1 with an integrated woofer can be set in the fourth area 4, and the second sound generating module W2 with an integrated woofer can be set in the fifth area 5. For example, the sound generating module including a woofer can be set in one or more of the fourth area 4 and the fifth area 5. As another example, the sound generating module including a woofer can be set in the third area 3. As another example, the third sound generating module 1500C can be configured to include a sound generating module of a woofer. Therefore, the sound generating module including a woofer can be set in one or more of the first area 1 to the fifth area 5, and can output the sound of a bass band, thereby providing a display device for outputting the sound of a bass band, a mid-range band, and a treble band. For example, the sound generating module can be driven based on the same signal or a mono signal applied thereto.

[0520] Figure 25A and Figure 25B A sound generating module according to another embodiment of the present disclosure is shown.

[0521] The sound generating module 1800 according to another embodiment of the present disclosure may be a woofer-integrated sound generating module, a hybrid sound generating module, and a sound generating module with a woofer, but the term is not limited thereto. Figure 25A is a front view of the sound generating module, and Figure 25B is a cross-sectional view of the sound generating module.

[0522] Reference Figure 25A and Figure 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 provided on the rear surface of the display panel, and the second sound generating device 1802 may be spaced apart from the rear surface of the display panel.

[0523] The sound generating module 1800 may include a frame for accommodating the first sound generating device 1801 and the second sound generating device 1802. The frame may include a lower frame 1610a supporting the lower portion of each of the first sound generating device 1801 and the second sound generating device 1802, and a side frame 1610b connected to the lower frame 1610a. The frame may be a yoke, but the term is not limited thereto.

[0524] The lower frame 1610a can support the magnet 1620. The magnet 1620 can be shared by the first sound generating device 1801 and the second sound generating device 1802. For example, the bobbin 1650a of the first sound generating device 1801 and the coil 1660a near the bobbin 1650a can be arranged near the magnet 1620. For example, the second bobbin 1650b of the second sound generating device 1802 and the second coil 1660b near the second bobbin 1650b can be arranged near the magnet 1620. For example, the lower frame 1610a and the plate 1611 can be respectively arranged below and above the magnet 1620, and can increase the magnetic flux density generated by the magnet 1620, the coil 1660a, and the second coil 1660b, thereby enhancing the vibration characteristics. The lower frame 1610a can be a yoke, but the term is not limited to this.

[0525] The side frame 1610b may be connected to the lower frame 1610a and may include at least one hole 217 for outputting sound. For example, the hole 217 may be a vent. For example, the hole 217 may output the bass-band sound generated by the vibration plate 214b of the second sound generating device 1802 in the air gap of the sound generating module 1800 to the rear area behind the display panel 110.

[0526] The side frame 1610b may include a conductive material and may control the magnetic flux generated by the magnet 1620. For example, the side frame 1610b may surround the magnet 1620 separately from the magnet 1620, thereby allowing the magnetic flux generated by the magnet 1620 to be concentrated within the interior of the second bobbin 1650b, thereby preventing magnetic flux leakage. The side frame 1610b may be a yoke, but the term is not limited to this. The hole 217 may be provided in the side frame 1610b, and further, may be provided in the lower frame 1610a, and may be provided in an area connected to the side frame 1610b and the lower frame 1610a. The side frame 1610b may be connected to the back cover using a connecting member 1710 such as a nut, or may be provided in the display panel 110.

[0527] The first sound generating device 1801 may include a magnet 1620 disposed on a frame, a bobbin 1650a close to the magnet 1620, and a coil 1660a and a damper 1670a close to the bobbin 1650a. For example, their description is similar to that described above with reference to Figure 3A-Figure 3E 、 Figure 6 and Figure 14 descriptions are given, and therefore their detailed descriptions are omitted.

[0528] The magnet 1620 may be disposed on the lower frame 1610a. For example, the magnet 1620 may be disposed 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, the magnet 1620 may be surrounded by the lower frame 1610a and the plate 1611, so that the magnetic flux generated by the magnet 1620 may be concentrated inside the bobbin 1650a and may be controlled.

[0529] The bobbin 1650a can be attached to the rear surface of the bobbin ring 1652a. For example, when a sound-generating current is applied to the coil 1660a wound around the outer circumference of the bobbin 1650a, thereby generating a magnetic field in the first sound generating device 1801, the display panel can vibrate based on the magnetic field using the bobbin ring 1652a. The bobbin ring 1652a can be positioned 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 sound in the mid- and high-pitched range.

[0530] The second sound generating device 1802 may include a magnet 1620 provided on a frame, a plate 1611 located on the magnet 1620 , a second bobbin 1650 b located near the magnet 1620 , and a second coil 1660 b and a second damper 1670 b located near the second bobbin 1650 b .

[0531] The vibration plate 214b may be disposed on the second bobbin 1650b. For example, the vibration plate 214b may be spaced apart from the rear surface of the display panel 110, and heat generated in the second bobbin 1650b may be prevented from being transferred to the display panel.

[0532] When a sound-generating current is applied to the second coil 1660b wound around the outer circumferential surface of the second bobbin 1650b, thereby generating a magnetic field in the second sound generating device 1802, the second bobbin 1650b can vibrate the air layer or air gap around the vibrating plate 214b based on the magnetic field. For example, the front surface of the second bobbin 1650b can contact the vibrating plate 214b and vibrate the vibrating plate 214b based on whether current is applied thereto. The second sound generating device 1802 can output sound to areas forward and rearward relative to the vibrating plate 214b. For example, the second sound generating device 1802 can output sound in the bass band. For example, the sound generated by the vibrating plate 214b of the second sound generating device 1802 can include a first low-pitched sound propagating to the upper portion of the vibrating plate 214b and a second low-pitched sound propagating to the lower portion of the vibrating plate 214b. For example, the second sound generating device 1802 can be a woofer, but the term is not limited to this.

[0533] The magnet 1620 may be disposed on the lower frame 1610a. The plate 1611 may be spaced apart from the vibration plate 214b. The second bobbin 1650b may be disposed on the rear surface of the vibration plate 214b. For example, the second bobbin 1650b may surround the magnet 1620 and the plate 1611.

[0534] 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 spool 1650b of the second sound generating device 1802. For example, the second damper 1670b may be disposed between the vibration plate 214b of the second sound generating device 1802 and the first sound generating device 1801. The vibration plate 214b may not be in physical contact with the first sound generating device 1801. For example, the second damper 1670b may prevent sound interference between the first sound generating device 1801 and the second sound generating device 1802. An edge 1670c may be disposed on the vibration plate 214b. When the vibration plate 214b performs vertical movement, the edge 1670c may prevent deformation (e.g., twisting of the vibration plate 214b), thereby providing clear sound quality and enhancing the reliability of the sound generating module 1800. The second damper 1670b may be a first suspension, and the edge 1670c may be a second suspension.

[0535] Magnet 1620 of first sound generating device 1801 and second magnet 1620 of second sound generating device 1802 can have opposite magnetic fields. First sound generating device 1801 can directly vibrate the display panel to output high-pitched sound to the front area in front of the display panel, and second sound generating device 1802 can output low-pitched sound to the rear area behind the display panel. Therefore, because first sound generating device 1801 and second sound generating device 1802 have opposite magnetic fields, the vibration of each of first sound generating device 1801 and second sound generating device 1802 can be independently driven or controlled.

[0536] Therefore, the sound generating module with an integrated woofer can include a woofer disposed adjacent to the sound generating module. The sound generating module can be disposed on the rear surface of the display panel and can generate mid- and high-pitched sounds, while the woofer can be separated from the rear surface of the display panel and can perform vertical vibrations to generate low-pitched sounds. For example, the sound generating module and the woofer can be driven based on different sound signals or voice signals applied thereto. Thus, the sound generating module with an integrated woofer can enhance low-pitched sounds.

[0537] Figure 26A and Figure 26BA display device including a sound generating module according to another embodiment of the present disclosure is shown.

[0538] Reference Figure 26A and Figure 26B , at least one sound generating module may be provided in at least one of the first area 1, the second area 2, the third area 3, the fourth area 4, and the fifth area 5. For example, the first sound generating module 1500L may be provided in the first area 1 of the rear surface of the display panel 110, and the fourth sound generating module 1500HL may be provided in the fourth area 4 of the rear surface of the display panel 110. The second sound generating module 1500R may be provided in the second area 2 of the rear surface of the display panel 110, and the fifth sound generating module 1500HR may be provided in the fifth area 5 of the rear surface of the display panel 110. The third sound generating module 1500C may be provided in the third area 3 of the rear surface of the display panel 110. As another example, as described above with reference to Figure 22 As described above, the first to fifth sound generating modules may be provided on the rear surface of the back cover 300. For example, the first to fifth sound generating modules may be provided in a module structure.

[0539] The first sound generating module 1500L may be a left channel of the display panel 110, and the fourth sound generating module 1500HL may be a top left channel of the display panel 110. The second sound generating module 1500R may be a right channel of the display panel 110, and the fifth sound generating module 1500HR may be a top right channel of the display panel 110. The third sound generating module 1500C may be a center channel of the display panel 110.

[0540] Reference Figure 26A and Figure 26BThe first sound generating module 1500L can be arranged symmetrically with the fourth sound generating module 1500HL, but is not limited to this. For example, the first sound generating module 1500L can be arranged on the same line as the fourth sound generating module 1500HL, but is not limited to this. For example, the sound reproduction positions can be aligned on the same line, thereby achieving an effect such as sound reproduction at the same location compared to an asymmetrical structure. This can enhance the recognition of the sound location, thereby improving sound localization. For example, the second sound generating module 1500R can be arranged symmetrically with the fifth sound generating module 1500HR. For example, the second sound generating module 1500R can be arranged on the same line as the fifth sound generating module 1500HR, but is not limited to this. For example, the sound reproduction positions can be aligned on the same line, thereby achieving an effect such as sound reproduction at the same location compared to an asymmetrical structure. This can enhance the recognition of the sound location, thereby improving sound localization. For example, the first sound generating module 1500L and the fourth sound generating module 1500HL may be arranged symmetrically with the second sound generating module 1500R and the fifth sound generating module 1500HR, but the present disclosure is not limited thereto. For example, the first sound generating module 1500L and the fourth sound generating module 1500HL may be arranged on the same line as the second sound generating module 1500R and the fifth sound generating module 1500HR, but embodiments of the present disclosure are not limited thereto.

[0541] Reference Figure 26A First sound generating module 1500L and second sound generating module 1500R can be arranged on the same line as third sound generating module 1500C, but the arrangement is not limited thereto. For example, the sound reproduction positions can be aligned on the same line, thereby achieving an effect such as sound reproduction at the same position compared to an asymmetrical structure. This can enhance the recognition of the sound position, thereby enhancing the localization of the sound.

[0542] Reference Figure 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, but the embodiments of the present disclosure are not limited thereto. For example, the first sound generating module 1500L and the second sound generating module 1500R can be arranged on different lines from the third sound generating module 1500C, but the embodiments of the present disclosure 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. For example, the first sound generating module 1500L may be separated from the fourth sound generating module 1500HL disposed in the fourth area 4. Therefore, the sound of the lower portion of the display panel 110 may be more vividly realized in the first sound generating module 1500L, and a sound for distinguishing the difference between the sound of the first sound generating module 1500L and the sound of the fourth sound generating module 1500HL may be realized based on the distance between the first sound generating module 1500L and the fourth sound generating module 1500HL. Furthermore, the second sound generating module 1500R may be separated from the fifth sound generating module 1500HR disposed in the fifth area 5. Therefore, the sound of the lower portion of the display panel 110 may be more vividly realized in the second sound generating module 1500R, and a sound for distinguishing the difference between the sound of the second sound generating module 1500R and the sound of the fifth sound generating module 1500HR may be realized based on the distance between the second sound generating module 1500R and the fifth sound generating module 1500HR.

[0543] The fourth sound generating module 1500HL may be provided in the fourth region 4, the fifth sound generating module 1500HR may be provided in the fifth region 5, and no sound generating module may be provided in the sixth region 6 between the fourth region 4 and the fifth region 5. Therefore, vibrations of each of the fourth sound generating module 1500HL and the fifth sound generating module 1500HR may be attenuated or absorbed in the sixth region 6 of the display panel 110, thereby preventing or reducing the transmission of sound from the fourth region 4 to the fifth region 5, and preventing or reducing the transmission of sound from the fifth region 5 to the fourth region 4. Consequently, degradation in sound quality caused by sound interference occurring in the fourth sound generating module 1500HL and the fifth sound generating module 1500HR may be reduced, and the sound characteristics of the mid- and high-pitched sound bands may be further enhanced.

[0544] Therefore, the first sound generating module 1500L and the fourth sound generating module 1500HL can be disposed in the first area 1 and the fourth area 4, which are the left area of ​​the rear surface of the display panel 110, and can vibrate the left area of ​​the display panel 110. The second sound generating module 1500R and the fifth sound generating module 1500HR can be disposed in the second area 2 and the fifth area 5, which are the right area of ​​the rear surface of the display panel 110, and can vibrate the right area of ​​the display panel 110. The third sound generating module 1500C can be disposed in the third area 3, which is the central area of ​​the rear surface of the display panel 110, and can vibrate the central area 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 receive different vibration signals and can each be driven independently. For example, the first sound generating module 1500L and the fourth sound generating module 1500HL may generate sound by using the left area of ​​the rear surface of the display panel 110 as a vibration plate, and the second sound generating module 1500R and the fifth sound generating module 1500HR may generate sound by using the right area of ​​the rear surface of the display panel 110 as a vibration plate. In addition, the third sound generating module 1500C may generate sound by using the central area of ​​the display panel 110 as a vibration plate.

[0545] In a display device according to an embodiment of the present disclosure, a woofer may be provided to further enhance the sound of the bass band. For example, one or more woofers may be further provided below at least one of the first sound generating module 1500L and the second sound generating module 1500R. For example, one or more woofers may also be provided below at least one of the first area 1 and the second area 2. For example, the first woofer W3 may be provided below the first area 1 of the display panel 110. For example, the first woofer W3 may be provided below the first sound generating module 1500L. For example, the second woofer W4 may be provided below the second area 2 of the display panel 110. For example, the second woofer W4 may be provided below the second sound generating module 1500R. Therefore, the first woofer W3 and the second woofer W4 may output the sound of the bass band. 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 of about 80 Hz to about 40 kHz, and the first woofer W3 and the second woofer W4 can output sounds of 80 Hz or lower. Therefore, the display device can output 5.1 channel sound.

[0546] Compared to sound generation modules located on the left and right sides of the display panel, since the sound generation modules are further located at the top and bottom of the display panel relative to its width, the left and right sounds, as well as the top and bottom sounds, can be enhanced, allowing the user to experience a sound field that feels like real sound. For example, the addition of the fourth sound generation module 1500HL and the fifth sound generation module 1500HR allows sound to be output from the top of the display panel 110, thereby providing a display device that implements stereo sound, including left and right sounds, as well as top and bottom sounds. Thus, left and right sounds corresponding to the left and right images, as well as top and bottom sounds corresponding to the top and bottom images, can be implemented. This allows for true stereo sound, including stereo left and right sounds, as well as stereo top and bottom sounds, to be provided, providing the user with real sound rather than imaginary sound. Consequently, true stereo sound or surround sound, including stereo left and right sounds, as well as stereo top and bottom sounds, can be provided to the user, enhancing the sense of reality. Therefore, in theaters, private movie theaters, and devices such as televisions, users can simultaneously experience real sounds and images that are similar to or the same as reality, and for example, can experience a real AV (audio-visual) or Dolby sound system.

[0547] In addition, when 23A to 23D Implemented in the soundboard Figure 24A and Figure 24B When the multi-channel sound generation module is provided, a real stereo or surround sound including real sound of stereo left and right sounds and stereo top and bottom sounds can be provided to the user, thereby enhancing the sense of reality.

In addition, a stereo sound can be provided to provide the user with an immersive experience and a sense of reality.

For example, the eleventh region 11 may be a 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. Reference numerals 1 to 11 representing regions in the first to eleventh regions may be arbitrarily displayed, and the reference numerals 1 to 11 and the classification of the first to eleventh regions do not limit the description of the present disclosure. The description related thereto may be applied identically or similarly to the following: Figures 28 to 44C .

[0550] At least one sound generating module may be provided in at least one of the first to eleventh regions 1 to 11. For example, the first sound generating module 1500L may be provided in the first region 1 of the rear surface of the display panel 110, the fourth sound generating module 1500HL may be provided in the fourth region 4 of the rear surface of the display panel 110, and the seventh sound generating module 1500BL may be provided in the seventh region 7 of the rear surface of the display panel 110.

The tenth sound generating module 1500LC may be disposed in the tenth area 10 of the rear surface of the display panel 110, and the eleventh sound generating module 1500RC may be disposed in the eleventh area 11 of the rear surface of the display panel 110. As another example, as described above with reference to Figure 22 As described above, the first to eleventh sound generating modules may be provided on the rear surface of the rear cover. For example, the first to eleventh sound generating modules may be provided in a module structure.

[0551] 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 top 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.

[0552] For example, 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, but is not limited to this. For example, the first sound generating module 1500L can 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 to this. For example, the sound reproduction positions can be aligned on the same line, thereby achieving an effect such as reproducing sounds at the same position compared to an asymmetrical structure. As a result, the recognition of the sound position can be enhanced, thereby enhancing the localization of the sound.

[0553] For example, 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, but is not limited to this. For example, the second sound generating module 1500R can be arranged on the same line as the fifth sound generating module 1500HR and / or the eighth sound generating module 1500BR, but is not limited to this. For example, the sound reproduction positions can be aligned on the same line, thereby achieving an effect such as reproducing sounds at the same position compared to an asymmetrical structure. Therefore, the recognition of the sound position can be enhanced, thereby enhancing the localization of the sound.

[0554] For example, 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, but is not limited to this. For example, the third sound generating module 1500C can be arranged on the same line as the sixth sound generating module 1500HC and / or the ninth sound generating module 1500BC, but is not limited to this. For example, the sound reproduction positions can be aligned on the same line, thereby achieving an effect such as sound reproduction at the same position compared to an asymmetrical structure. This can enhance the recognition of the sound position, thereby enhancing the localization of the sound.

[0555] For example, the tenth sound generating module 1500LC and the eleventh sound generating module 1500RC can 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 the present invention is not limited thereto. For example, the tenth sound generating module 1500LC and the eleventh sound generating module 1500RC can be arranged on the same line as at least one of the first sound generating module 1500L, the second sound generating module 1500R, and the third sound generating module 1500C, but the present invention is not limited thereto. For example, the sound reproduction positions can be aligned on the same line, thereby achieving an effect such as reproducing sounds at the same position compared to an asymmetrical structure. Therefore, the recognition of the sound position can be enhanced, thereby enhancing the localization of the sound.

[0556] For example, one of the fourth sound generating module 1500HL and the fifth sound generating module 1500HR can be arranged symmetrically with the sixth sound generating module 1500HC, but the present invention is not limited to this. For example, one of the fourth sound generating module 1500HL and the fifth sound generating module 1500HR can be arranged on the same line as the sixth sound generating module 1500HC, but the present invention is not limited to this. For example, the sound reproduction positions can be aligned on the same line, thereby achieving an effect such as reproducing sounds at the same position compared to an asymmetrical structure. This can enhance the recognition of the sound position and thus improve the localization of the sound. 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 can be arranged symmetrically with the third sound generating module 1500C, but the present invention is not limited to this. 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 on the same line as the third sound generating module 1500C, but the arrangement is not limited thereto. For example, the sound reproduction positions may be aligned on the same line, thereby achieving an effect such as sound reproduction at the same location compared to an asymmetrical structure. This can enhance the recognition of the sound location, thereby improving sound localization. For example, one of the seventh sound generating module 1500BL and the eighth sound generating module 1500BR may be arranged symmetrically with the ninth sound generating module 1500BC, but the arrangement is not limited thereto. For example, one of the seventh sound generating module 1500BL and the eighth sound generating module 1500BR may be arranged on the same line as the ninth sound generating module 1500BC, but the arrangement is not limited thereto. For example, the sound reproduction positions may be aligned on the same line, thereby achieving an effect such as sound reproduction at the same location compared to an asymmetrical structure. This can enhance the recognition of the sound location, thereby improving sound localization.

[0557] Therefore, the first sound generating module 1500L, the fourth sound generating module 1500HL, and the seventh sound generating module 1500BL can be disposed in the first area 1, the fourth area 4, and the seventh area 7, which are the left area of ​​the rear surface of the display panel 110, and can vibrate the left area 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 disposed in the second area 2, the fifth area 5, and the eighth area 8, which are the right area of ​​the rear surface of the display panel 110, and can vibrate the right area 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 disposed in the third area 3, the sixth area 6, and the ninth area 9, which are the central area of ​​the rear surface of the display panel 110, and can vibrate the central area 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 receive different vibration signals and can each 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 sound by using the left area of ​​the rear surface of the display panel 110 as a vibration plate. The second sound generating module 1500R, the fifth sound generating module 1500HR, and the eighth sound generating module 1500BR can generate sound by using the right area of ​​the rear surface of the display panel 110 as a vibration plate. 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 area of ​​the rear surface of the display panel 110 as a vibration plate. The tenth sound generating module 1500LC and the eleventh sound generating module 1500RC can generate sound by using the left area, the central area, and the right area of ​​the rear surface of the display panel 110 as vibration plates. For example, the sixth sound generating module 1500HC can generate sound toward the upper portion 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 toward the upper portion of the display panel 110, thereby enhancing the sound of the upper portion 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 may generate sound toward the lower portion of the display panel 110 , thereby reinforcing the sound of the lower portion of the display panel 110 .

[0558] In addition, a woofer may be provided to further enhance the sound of the bass band. For example, one or more woofers may also be provided below at least one of the seventh area 7 and the eighth area 8. For example, one or more woofers may also be provided 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 provided below the seventh area 7 of the display panel 110. For example, the first woofer W3 may be provided below the seventh sound generating module 1500BL. For example, the second woofer W4 may be provided below the eighth area 8 of the display panel 110. For example, the second woofer W4 may be provided below the eighth sound generating module 1500BR. Therefore, the first woofer W3 and the second woofer W4 may output the sound of the bass band.

[0559] As another example, the first woofer W3 and the second woofer W4 may not be provided, and 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 having a woofer. For example, the first sound generating module W1 with an integrated woofer may be provided in the seventh area 7, and the second sound generating module W2 with an integrated woofer may be provided in the eighth area 8. For example, the sound generating module having a woofer may be provided in one or more of the seventh area 7 and the eighth area 8. The description of the sound generating module W1 with an integrated woofer and the sound generating module W2 with an integrated woofer is the same as that described above with reference to FIG. Figures 24A to 25B The descriptions given are the same, so their descriptions are omitted.

[0560] When the first integrated woofer sound generating module W1 is positioned in the seventh area 7, the first integrated woofer sound generating module W1 can be positioned symmetrically with one of the first and fourth sound generating modules 1500L and 1500HL. For example, the first integrated woofer sound generating module W1 can be positioned on the same line as one of the first and fourth sound generating modules 1500L and 1500HL. When the second integrated woofer sound generating module W2 is positioned in the eighth area 8, the second integrated woofer sound generating module W2 can be positioned symmetrically with one of the second and fifth sound generating modules 1500R and 1500HR. For example, the second integrated woofer sound generating module W2 can be positioned on the same line as one of the second and fifth sound generating modules 1500R and 1500HR. For example, the sound reproduction positions can be aligned on the same line, thereby achieving an effect such as sound reproduction at the same location compared to an asymmetrical structure. This can enhance the recognition of the sound location and thus improve sound localization.

[0561] As another example, when the first integrated woofer sound generating module W1 is positioned in the seventh area 7, the first integrated woofer sound generating module W1 may be positioned asymmetrically with respect to one of the first and fourth sound generating modules 1500L and 1500HL. For example, the first integrated woofer sound generating module W1 may be positioned on a different line than one of the first and fourth sound generating modules 1500L and 1500HL. When the second integrated woofer sound generating module W2 is positioned in the eighth area 8, the second integrated woofer sound generating module W2 may be positioned asymmetrically with respect to one of the second and fifth sound generating modules 1500R and 1500HR. For example, the second integrated woofer sound generating module W2 may be positioned on a different line than one of the second and fifth sound generating modules 1500R and 1500HR. For example, the first integrated woofer sound generating module W1 and the second integrated woofer sound generating module W2 may be positioned on a different line than the third sound generating module 1500C. For example, it is possible to reduce constructive or destructive sound interference caused by vibration interference between the vibration and standing waves generated by the sound generating module W1 of the first integrated woofer and the vibration and standing waves generated by the fourth sound generating module 1500HL or the seventh sound generating module 1500BL. Undesirable constructive or destructive sound interference caused by external interference other than the vibration based on the reproduced sound source can cause sound distortion, thereby reducing sound quality. The asymmetric structure between the sound generating module W1 of the first integrated woofer and one of the fourth sound generating module 1500HL and the seventh sound generating module 1500BL can prevent undesirable interference, thereby reproducing natural sound similar to the original sound. It is also possible to reduce constructive or destructive sound interference caused by vibration interference between the vibration and standing waves generated by the sound generating module W2 of the second integrated woofer and the vibration and standing waves generated by the fifth sound generating module 1500HR or the eighth sound generating module 1500BR. In addition to the vibration based on the reproduced sound source, unwanted constructive or destructive interference of sound caused by external interference may cause sound distortion, thereby reducing the sound quality, and the asymmetric structure between the sound generating module W2 of the second integrated woofer and one of the fifth sound generating module 1500HR and the eighth sound generating module 1500BR can prevent unwanted interference, thereby reproducing natural sound similar to the original sound.

[0562] As another example, the first woofer W3 and the second woofer W4 may not be provided, and 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 or a sound generating module having a woofer. For example, the first sound generating module W1 with an integrated woofer may be provided in the first area 1, and the second sound generating module W2 with an integrated woofer may be provided in the second area 2. For example, the sound generating module including the woofer may be provided in one or more of the first area 1 and the second area 2. The description of the sound generating module W1 with an integrated woofer and the sound generating module W2 with an integrated woofer is the same as that described above with reference to Figures 24A to 25B The descriptions given are the same, so their descriptions are omitted. The descriptions related thereto are the same as the description of the example in which the sound generating module W1 of the first integrated woofer and the sound generating module W2 of the second integrated woofer are set in the seventh area 7 and the eighth area 8, so they are omitted.

[0563] As another example, the first woofer W3 and the second woofer W4 may not be provided, and 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. For example, the first sound generating module W1 with an integrated woofer may be provided in the tenth area 10, and the second sound generating module W2 with an integrated woofer may be provided in the eleventh area 11. For example, a sound generating module including a woofer may be provided in one or more of the tenth area 10 and the eleventh area 11.

[0564] As another example, the first woofer W3 and the second woofer W4 may not be provided, and 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, the first sound generating module W1 with an integrated woofer may be provided in the fourth area 4, and the second sound generating module W2 with an integrated woofer may be provided in the fifth area 5. For example, a sound generating module including a woofer may be provided in one or more of the fourth area 4 and the fifth area 5.

[0565] As another example, the first woofer W3 and the second woofer W4 may not be provided, and 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. For example, the first sound generating module W1 with an integrated woofer may be provided in the sixth area 6, and the second sound generating module W2 with an integrated woofer may be provided in the ninth area 9. For example, a sound generating module including a woofer may be provided in one or more of the sixth area 6 and the ninth area 9. As another example, a sound generating module including a woofer may be provided in the third area 3. For example, the third sound generating module 1500C may be configured as a sound generating module including a woofer.

[0566] Therefore, a woofer may not be separately provided, and a sound generating module integrating a woofer may be provided in one or more of the first to eleventh areas 1 to 11, and may output sound in the bass band, thereby providing a display device for outputting sound in the bass band, the mid-range band, and the treble band. For example, the sound generating module may be driven based on the same signal or a mono signal applied thereto.

[0567] 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 sounds of about 80 Hz to about 40 kHz. The first woofer W3 and the second woofer W4 can output sounds of 80 Hz or lower. Therefore, the display device can output 11.1 channel sound.

[0568] The display device according to the embodiment of the present disclosure can realize the left and right sounds corresponding to the left and right images and the top and bottom sounds corresponding to the upper and lower images, and can realize real stereo sound including stereo left and right sounds and stereo top and bottom sounds of real sounds, thereby providing real sounds rather than virtual sounds to the user. Therefore, real stereo or surround sound including stereo left and right sounds and stereo top and bottom sounds of real sounds can be provided to the user, thereby enhancing the sense of reality. Therefore, in theaters, private theaters, and devices such as televisions, users can simultaneously experience real sounds and images similar to or identical to reality, and, for example, can experience a real AV or Dolby sound system.

[0569] In addition, when 23A to 23D Implemented in the soundboard Figure 24A and Figure 24B When the multi-channel sound generation module is provided, the user can be provided with real sound or real stereo or surround sound including stereo left and right sounds and stereo top and bottom sounds, thereby enhancing the sense of reality. 23A to 23D Set in the soundboard Figure 24A and Figure 24B When the multi-channel sound generation module and the projection or image reproduction device are provided, a real AV or Dolby sound system can be provided so that the user can simultaneously feel the real sound and image similar to or the same as the reality. In addition, stereo sound can be provided to provide the user with an immersive experience and a sense of reality. Figures 1 to 22 As described above, a modular sound generating module can be applied. Therefore, when the sound generating module is provided, the degree of freedom in designing the display device or the back cover can be improved.

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 arranged on the same line as the fifth sound generating module 1500HR and / or the eighth sound generating module 1500BR, but is not limited thereto. 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, third sound generating module 1500C may be arranged on the same line as sixth sound generating module 1500HC and / or ninth sound generating module 1500BC, but the arrangement is not limited thereto. For example, the sound reproduction positions may be aligned on the same line, thereby achieving an effect such as sound reproduction at the same location compared to an asymmetrical structure. This enhances the recognition of sound locations and thus improves sound localization.

[0575] For example, the tenth sound generating module 1500LC can be arranged symmetrically with the twelfth sound generating module 1500HLC and / or the fourteenth sound generating module 1500BLC, but is not limited to this. For example, the tenth sound generating module 1500LC can be arranged on the same line as the twelfth sound generating module 1500HLC and / or the fourteenth sound generating module 1500BLC, but is not limited to this. For example, the eleventh sound generating module 1500RC can be arranged symmetrically with the thirteenth sound generating module 1500HRC and / or the fifteenth sound generating module 1500BRC, but is not limited to this. For example, the eleventh sound generating module 1500RC can be arranged on the same line as the thirteenth sound generating module 1500HRC and / or the fifteenth sound generating module 1500BRC, but is not limited to this. For example, the sound reproduction positions can be aligned on the same line, thereby achieving an effect such as reproducing sounds at the same position compared to an asymmetrical structure. As a result, the recognition of the sound position can be enhanced, thereby enhancing the localization of the sound.

[0576] For example, one of the fourth sound generating module 1500HL, the fifth sound generating module 1500HR, and the sixth sound generating module 1500HC may be arranged symmetrically with one of the twelfth sound generating module 1500HLC and the thirteenth sound generating module 1500HRC, but the present invention is not limited thereto. For example, one of the fourth sound generating module 1500HL, the fifth sound generating module 1500HR, and the sixth sound generating module 1500HC may be arranged on the same line with one of the twelfth sound generating module 1500HLC and the thirteenth sound generating module 1500HRC, but the present invention is not limited thereto. For example, one of the first sound generating module 1500L, the second sound generating module 1500R, and the third sound generating module 1500C may be arranged symmetrically with one of the tenth sound generating module 1500LC and the eleventh sound generating module 1500RC, but the present invention is not limited thereto. For example, one of the first, second, and third sound generating modules 1500L, 1500R, and 1500C may be arranged on the same line as one of the tenth and eleventh sound generating modules 1500LC, 1500RC. For example, one of the seventh, eighth, and ninth sound generating modules 1500BL, 1500BR, and 1500BC may be arranged symmetrically with one of the fourteenth and fifteenth sound generating modules 1500BLC, 1500BRC, but is not limited to this. For example, one of the seventh, eighth, and ninth sound generating modules 1500BL, 1500BR, and 1500BC may be arranged on the same line as one of the fourteenth and fifteenth sound generating modules 1500BLC, 1500BRC, but is not limited to this. For example, the sound reproduction positions may be aligned on the same line, thereby achieving an effect such as sound reproduction at the same location compared to an asymmetrical structure. This may enhance the recognition of the sound location, thereby enhancing the localization of the sound.

[0577] In addition, a subwoofer may be provided to further enhance the sound in the bass band. For example, a subwoofer may be further provided below at least one of the first to fifteenth regions 1, 15. For example, a subwoofer may be further provided below at least one of the first to fifteenth sound generating modules 1500L, 1500BRC. For example, the first subwoofer W3 may be provided below the seventh region 7 of the display panel 110. For example, the first subwoofer W3 may be provided below the seventh sound generating module 1500BL. For example, the first subwoofer W3 may be provided between the seventh region 7 and the fourteenth region 14. For example, the second subwoofer W4 may be provided below the eighth region 8 of the display panel 110. For example, the second subwoofer W4 may be provided below the eighth sound generating module 1500BR. For example, the second subwoofer W4 may be provided between the eighth region 8 and the fifteenth region 15. Thus, the first and second subwoofers W3 and W4 may output the sound in the bass band.

[0578] As another example, the first woofer W3 and the second woofer W4 may not be provided, and 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. For example, the first sound generating module W1 with an integrated woofer may be provided in the seventh area 7, and the second sound generating module W2 with an integrated woofer may be provided in the eighth area 8. For example, the sound generating module including a woofer may be provided in one or more of the seventh area 7 and the eighth area 8. The description of the sound generating module W1 with an integrated woofer and the sound generating module W2 with an integrated woofer is the same as that described above with reference to FIG. Figures 24A to 25B The descriptions given are the same, so their descriptions are omitted.

[0579] When the first integrated woofer sound generating module W1 is positioned in the seventh area 7, the first integrated woofer sound generating module W1 can be positioned symmetrically with one of the first and fourth sound generating modules 1500L and 1500HL. For example, the first integrated woofer sound generating module W1 can be positioned on the same line as one of the first and fourth sound generating modules 1500L and 1500HL. When the second integrated woofer sound generating module W2 is positioned in the eighth area 8, the second integrated woofer sound generating module W2 can be positioned symmetrically with one of the second and fifth sound generating modules 1500R and 1500HR. For example, the second integrated woofer sound generating module W2 can be positioned on the same line as one of the second and fifth sound generating modules 1500R and 1500HR. For example, the sound reproduction positions can be aligned on the same line, thereby achieving an effect such as sound reproduction at the same location compared to an asymmetrical structure. This can enhance the recognition of the sound location and thus improve sound localization.

[0580] As another example, when the first integrated woofer sound generating module W1 is positioned in the seventh area 7, the first integrated woofer sound generating module W1 may be positioned asymmetrically with respect to one of the first and fourth sound generating modules 1500L and 1500HL. For example, the first integrated woofer sound generating module W1 may be positioned on a different line than one of the first and fourth sound generating modules 1500L and 1500HL. When the second integrated woofer sound generating module W2 is positioned in the eighth area 8, the second integrated woofer sound generating module W2 may be positioned asymmetrically with respect to one of the second and fifth sound generating modules 1500R and 1500HR. For example, the second integrated woofer sound generating module W2 may be positioned on a different line than one of the second and fifth sound generating modules 1500R and 1500HR. For example, the first integrated woofer sound generating module W1 and the second integrated woofer sound generating module W2 may be positioned on a different line than the third sound generating module 1500C. For example, it is possible to reduce constructive or destructive sound interference caused by vibration interference between the vibration and standing waves generated by the sound generating module W1 of the first integrated woofer and the vibration and standing waves generated by the fourth sound generating module 1500HL or the seventh sound generating module 1500BL. Undesirable constructive or destructive sound interference caused by external interference other than the vibration based on the reproduced sound source can cause sound distortion, thereby reducing sound quality. The asymmetric structure between the sound generating module W1 of the first integrated woofer and one of the fourth sound generating module 1500HL and the seventh sound generating module 1500BL can prevent undesirable interference, thereby reproducing natural sound similar to the original sound. It is also possible to reduce constructive or destructive sound interference caused by vibration interference between the vibration and standing waves generated by the sound generating module W2 of the second integrated woofer and the vibration and standing waves generated by the fifth sound generating module 1500HR or the eighth sound generating module 1500BR. In addition to the vibration based on the reproduced sound source, unwanted constructive or destructive interference of sound caused by external interference may cause sound distortion, thereby reducing the sound quality, and the asymmetric structure between the sound generating module W2 of the second integrated woofer and one of the fifth sound generating module 1500HR and the eighth sound generating module 1500BR can prevent unwanted interference, thereby reproducing natural sound similar to the original sound.

[0581] As another example, the first woofer W3 and the second woofer W4 may not be provided, and 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 or a sound generating module having a woofer. For example, the first sound generating module W1 with an integrated woofer may be provided in the first area 1, and the second sound generating module W2 with an integrated woofer may be provided in the second area 2. For example, the sound generating module including the woofer may be provided in one or more of the first area 1 and the second area 2. The description of the sound generating module W1 with an integrated woofer and the sound generating module W2 with an integrated woofer is the same as that described above with reference to Figures 24A to 25B The descriptions given are the same, so their descriptions are omitted. The descriptions related thereto are the same as the description of the example in which the sound generating module W1 of the first integrated woofer and the sound generating module W2 of the second integrated woofer are set in the first area 1 and the second area 2, so they are omitted.

[0582] As another example, the first woofer W3 and the second woofer W4 may not be provided, and 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. For example, the first sound generating module W1 with an integrated woofer may be provided in the tenth area 10, and the second sound generating module W2 with an integrated woofer may be provided in the eleventh area 11. For example, the sound generating module including a woofer may be provided in one or more of the tenth area 10 and the eleventh area 11. The description of the sound generating module W1 with an integrated woofer and the sound generating module W2 with an integrated woofer is the same as that described above with reference to FIG. Figures 24A to 25B The descriptions given are the same, so their descriptions are omitted. The descriptions related thereto are the same as the description of the example in which the sound generating module W1 of the first integrated woofer and the sound generating module W2 of the second integrated woofer are provided in the tenth area 10 and the eleventh area 11, so they are omitted.

[0583] As another example, the first woofer W3 and the second woofer W4 may not be provided, and 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. For example, the first sound generating module W1 with an integrated woofer may be provided in the fourteenth area 14, and the second sound generating module W2 with an integrated woofer may be provided in the fifteenth area 15. For example, the sound generating module including a woofer may be provided in one or more of the fourteenth area 14 and the fifteenth area 15. The description of the sound generating module W1 with an integrated woofer and the sound generating module W2 with an integrated woofer is the same as that described above with reference to Figures 24A to 25B The descriptions given are the same, so their descriptions are omitted. The descriptions related thereto are the same as the description of the example in which the sound generating module W1 of the first integrated woofer and the sound generating module W2 of the second integrated woofer are arranged in the fourteenth area 14 and the fifteenth area 15, so they are omitted.

[0584] As another example, the first woofer W3 and the second woofer W4 may not be provided, and 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, the first sound generating module W1 with an integrated woofer may be provided in the fourth area 4, and the second sound generating module W2 with an integrated woofer may be provided in the fifth area 5. For example, a sound generating module including a woofer may be provided in one or more of the fourth area 4 and the fifth area 5.

[0585] As another example, the first woofer W3 and the second woofer W4 may not be provided, and 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. For example, the first sound generating module W1 with an integrated woofer may be provided in the twelfth area 12, and the second sound generating module W2 with an integrated woofer may be provided in the thirteenth area 13. For example, a sound generating module including a woofer may be provided in one or more of the twelfth area 12 and the thirteenth area 13.

[0586] As another example, the first woofer W3 and the second woofer W4 may not be provided, and 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. For example, the first sound generating module W1 with an integrated woofer may be provided in the sixth area 6, and the second sound generating module W2 with an integrated woofer may be provided in the ninth area 9. For example, a sound generating module including a woofer may be provided in one or more of the sixth area 6 and the ninth area 9. As another example, a sound generating module including a woofer may be provided in the third area 3. For example, the third sound generating module 1500C may be configured as a sound generating module including a woofer.

[0587] Therefore, a woofer may not be separately provided, and a sound generating module integrating a woofer may be provided in one or more of the first to fifteenth areas 1 to 15, and may output sound in the bass band, thereby providing a display device for outputting sound in the bass band, the mid-range band, and the treble band. For example, the sound generating module may be driven based on the same signal or a mono signal applied thereto.

[0588] 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 sounds of about 80 Hz to about 40 kHz. The first woofer W3 and the second woofer W4 can output sounds of 80 Hz or lower. Therefore, the display device can output 15.1 channel sound.

[0589] The display device according to the embodiment of the present disclosure can realize the left and right sounds corresponding to the left and right images and the top and bottom sounds corresponding to the upper and lower images, and can realize real stereo sound including stereo left and right sounds and stereo top and bottom sounds of real sounds, thereby providing real sounds rather than virtual sounds to the user. Therefore, real stereo or surround sound including stereo left and right sounds and stereo top and bottom sounds of real sounds can be provided to the user, thereby enhancing the sense of reality. Therefore, in theaters, private theaters, and devices such as televisions, users can simultaneously experience real sounds and images similar to or identical to reality, and, for example, can experience a real AV or Dolby sound system.

[0590] In addition, when 23A to 23D Implemented in the soundboard Figure 24A and Figure 24B When the multi-channel sound generation module is provided, a real stereo or surround sound including real sounds of stereo left and right sounds and stereo top and bottom sounds can be provided to the user, thereby enhancing the sense of reality. 23A to 23D Set in the soundboard Figure 24A and Figure 24B When the multi-channel sound generation module and the projection or image reproduction device are provided, a real AV or Dolby sound system can be provided so that the user can simultaneously feel the real sound and image similar to or the same as the reality. In addition, stereo sound can be provided to provide the user with an immersive experience and a sense of reality. Figures 1 to 22 As described above, a modular sound generating module can be applied. Therefore, when the sound generating module is provided, the degree of freedom in designing the display device or the back cover can be improved.

[0591] Figures 29A to 29E A sound generating module and a partition according to another embodiment of the present disclosure are shown.

[0592] Reference Figures 29A to 29E, the display panel 110 may include a first area 1 to a sixth area 6. The first area 1 to the sixth area 6 may have the same area, but are not limited thereto. For example, the first area 1 to the sixth area 6 may be arranged at equal intervals or distances. For example, all channels of the sound generation module provided in the first area 1 to the sixth area 6 may reproduce or output sounds having the same frequency domain or range, and therefore, the harmony between the channels may be uniform. Therefore, the difference in sound quality between a case with an acoustic effect (e.g., a case where the sound field is widened) and a case without an acoustic effect (e.g., a case where the sound field is not widened) may be reduced, and uniform or constant sound quality may be achieved. As another example, the area of ​​the first area 1, the second area 2, and the third area 3 may be larger than the area of ​​the fourth area 4, the fifth area 5, and the sixth area 6. For example, the low sound range of left and right stereo sound may be enhanced, thereby enhancing the quality of normal sound without acoustic effects. As another example, the area of ​​the fourth area 4, the fifth area 5, and the sixth area 6 may be smaller than the area of ​​the first area 1, the second area 2, and the third area 3. For example, the bass range of a channel associated with acoustic effects can be enhanced. Therefore, when reproducing sounds with acoustic effects, the sound field, which is the space used to express the sound, can be enlarged, thereby enhancing the acoustic effect that expresses the location of the sound. Therefore, the size of each of the first to sixth areas 1 to 6 can be adjusted based on the desired soundtrack.

[0593] Reference Figures 29A to 29E , a partition may also be provided near the sound generating module. The partition may be an air gap or space that generates sound when the display panel 110 vibrates. The air gap or space that generates or transmits sound may be referred to as a partition. The partition may separate the sound or may separate the sound channels, and may prevent or reduce the occurrence of unclear sound caused by sound interference. The partition may be referred to as a housing or a baffle, but the term is not limited thereto. In an embodiment, an example in which the partition is provided at the back cover will be described, but the embodiments of the present disclosure are not limited thereto. In other embodiments, the partition may be provided at the rear surface of the display panel 110. In order to illustrate the sound generating module and the partition, an example in which the partition is provided at the back cover will be described. For example, in the case in which the partition is provided at the back cover, the influence of the partition on the image quality of the display panel may be reduced. As described above with reference to Figure 22 As described above, when the sound generating module is provided on the rear cover, the partition may be provided on the rear cover.

[0594] Reference Figure 29AThe partition can separate the left and right sounds output from the sound generating modules disposed on the rear surface of the display panel 110. For example, the partition can be disposed between the back cover 300 and the display panel 110, corresponding to the first to sixth areas 1 to 6 of the display panel 110. For example, the fourth partition 1701 can be disposed between the first and fourth areas 1 and 4 and the third area 3. For example, the fourth partition 1701 can be disposed between the first and fourth areas 1 and 4 and the third and sixth areas 6. The fifth partition 1702 can be disposed between the second and fifth areas 2 and 5 and the third area 3. For example, the fifth partition 1702 can be disposed between the second and fifth areas 2 and 5 and the third and sixth areas 6. The fourth partition 1701 and the fifth partition 1702 can separate the left and right channels, or the left and right sounds, generated by the first and fourth integrated woofer sound generating modules W1 and 1500HL, and the second and fifth integrated woofer sound generating modules W2 and 1500HR.

[0595] In order to achieve stereo or stereophonic sound, a fourth sound generating module 1500HL and a fifth sound generating module 1500HR may also be provided, and a partition should also be provided to separate the channels or sounds generated by the fourth sound generating module 1500HL and the fifth sound generating module 1500HR from the channels or sounds generated by the first integrated woofer sound generating module W1, the second integrated woofer sound generating module W2, and the third sound generating module 1500C. When the fourth partition 1701 and the fifth partition 1702 are provided, the left sound and the right sound or the left channel and the right channel can be separated. A partition should be provided for generating the sound of each sound generating module so that the top sound or the top channel is separated, and the sound generating module provided in the area of ​​the rear surface of the display panel 110 realizes independent sound for each area.

[0596] The partition can be configured to separate the top sound channel of the display panel 110 from the bottom sound channel of the display panel 110. For example, the first partition 1721 can separate the top sound channel of the display panel 110 from the bottom sound channel of the display panel 110. For example, the first partition 1721 can separate the sound channel or sound generated by the fourth sound generating module 1500HL and the fifth sound generating module 1500HR disposed above the display panel 110 from the sound channel or sound generated by the first integrated woofer sound generating module W1, the second integrated woofer sound generating module W2, and the third sound generating module 1500C disposed below the display panel 110. The second partition 1722 can be disposed below the display panel 110 and can be separated from the driver used to drive the display panel 110. For example, the second partition 1722 can be disposed below the first integrated woofer sound generating module W1, the second integrated woofer sound generating module W2, and the third sound generating module 1500C. For example, the second partition 1722 may be separated from a driver for driving the first integrated woofer sound generating module W1 , the second integrated woofer sound generating module W2 , the third sound generating module 1500C, and the display panel 110 .

[0597] The first spacer 1721, the second spacer 1722, the fourth spacer 1701, and the fifth spacer 1702 may be provided on the back cover 300. For example, the first spacer 1721, the second spacer 1722, the fourth spacer 1701, and the fifth spacer 1702 may be provided on the front surface of the back cover 300. For example, the first spacer 1721, the second spacer 1722, the fourth spacer 1701, and the fifth spacer 1702 may be provided between the display panel 110 and the back cover 300. For example, the first spacer 1721, the second spacer 1722, the fourth spacer 1701, and the fifth spacer 1702 may be provided between the back surface of the display panel 110 and the front surface of the back cover 300.

[0598] The first spacer 1721, the second spacer 1722, the fourth spacer 1701, and the fifth spacer 1702 may be formed from 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 pad, adhesive, and bonding member. When each of the first spacer 1721, the second spacer 1722, the fourth spacer 1701, and the fifth spacer 1702 is formed from double-sided tape or double-sided foam pad, adhesion may be enhanced during attachment of the front surface of the rear cover 300 to the rear surface of the display panel 110. For example, the first spacer 1721, the second spacer 1722, the fourth spacer 1701, and the fifth spacer 1702 may be made of a material having a certain degree of elasticity capable of compression, such as, but not limited to, polyurethane, polyolefin, and / or polyethylene.

[0599] Reference Figure 29B A first spacer 1721, a fourth spacer 1701, and a fifth spacer 1702 may be provided, and a spacer 1750 may be provided between the back cover 300 and the display panel 110. For example, the spacer 1750 may be provided at an edge or periphery of the back cover 300. For example, the spacer 1750 may be provided at an edge or periphery of the front surface of the back cover 300. The spacer 1750 may cover the entire area of ​​the four outer sides of the front surface of the back cover 300. As another example, the spacer 1750 may be provided at an edge or periphery of the rear surface of the display panel 110. The spacer 1750 may cover the entire area of ​​the back cover 300 or the four outer sides of the rear surface of the display panel 110. For example, the spacer 1750 may be provided 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 provided along the shape of the display panel 110 to prevent the ripple phenomenon of the display panel 110. The ripple phenomenon may be caused by the thickness of the substrate configuring the display panel becoming thinner. Figure 4 or Figure 9 The shape of the connecting portion described above bounces to the screen of the display panel, and the ripple phenomenon can be a problem that the display panel is not flat or the back cover is not flat and the unevenness of the screen is seen. For example, when the partition 1750 is the above reference Figure 8 、 Figure 10 and Figures 19 to 21 When describing the adhesive member for attaching the back cover to the display panel, the adhesive member described above with reference to Figure 8 、 Figure 10 and Figures 19 to 21The adhesive member described above and the partition 1750 may be used as the adhesive member. However, the embodiments of the present disclosure are not limited thereto, and the adhesive for attaching the display panel to the back cover may be provided on the rear surface of the display panel or on the back cover.

[0600] During the placement of the first separator 1721, the fourth separator 1701, the fifth separator 1702, and the separator 1750, the first separator 1721 may be placed, the separator 1750 may be placed, and then the fourth separator 1701 and the fifth separator 1702 may be placed. As another example, the first separator 1721 may be placed, the fourth separator 1701 and the fifth separator 1702 may be placed, and then the separator 1750 may be placed. However, the order in which the separators are placed does not limit the description of the embodiments of the present disclosure. The separator 1750 may be placed first along the length of the back cover and then along the width. However, the order in which the separators are placed does not limit the description of the embodiments of the present disclosure. In the following embodiments, an example of placing the first separator 1721, the separator 1750, and then the fourth separator 1701 and the fifth separator 1702 is shown, but the embodiments of the present disclosure are not limited to this. Such descriptions may apply identically or similarly to the following embodiments.

[0601] Reference Figure 29C The shape of the first separator 1721 and the shape of the second separator 1722 can be implemented differently. The shape of the first separator 1721 and the shape of the second separator 1722 can be different from the shape of the display panel 110 or the shape of the fourth separator 1701 and the shape of the fifth separator 1702. For example, the first separator 1721 and the second separator 1722 can have a non-flat shape or can have a non-linear shape. When the separator has a non-flat shape or a non-linear shape, the separator can diffuse standing waves. For example, when the separator is implemented as a sawtooth shape, a triangle shape, and a triangle shape with inverted end corners, the standing waves can be diffused in various directions by the sawtooth shape, the triangle shape, and the triangle shape with inverted end corners, thereby enhancing the sound output characteristics. For example, the first separator 1721 and the second separator 1722 can have a sawtooth shape, a triangle shape, and a triangle shape with inverted end corners. For example, the sawtooth of the separator can be positioned toward the sound generating module. For example, when the separator has a triangular shape, the end of the triangle can be positioned toward the sound generating module. For example, when the partition has a triangular shape with rounded ends, the end of the triangular shape with rounded ends may be disposed toward the sound generating module.
