[0206] When interpreting an element, the element is interpreted as including an error or tolerance range even if there is no explicit description of such an error or tolerance range. When describing a positional relationship, for example, when the positional relationship between two components is described as, for example, "on", "above", "under", and "next to", one or more other components may be arranged between the two components unless more restrictive terms such as "only" or "directly" are used. When describing a temporal relationship, for example, when the time sequence is described as, for example, "after", "subsequently", "then", and "before", discontinuous cases may be included unless more restrictive terms such as "exactly", "immediately", or "directly" are used.

[0207] It should be understood that although the terms "first", "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, without departing from the scope of the present disclosure, the first element may be referred to as the second element, and similarly, the second element may be referred to as the first element.

[0208] When describing the elements of the present disclosure, terms such as "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 quantity of the corresponding elements should not be limited by these terms. Unless otherwise specified, the expression that an element "is connected", "is coupled" or "is attached" to another element or layer means that the element or layer can not only be directly connected or attached to another element or layer, but also be indirectly connected or attached to another element or layer and "there is" one or more intermediate elements or layers between the elements or layers.

[0209] 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, the meaning of "at least one of the first item, the second item and the third item" means all combinations of two or more of the first item, the second item and the third item and the first item or the second item or the third item.

[0210] In the description of an embodiment, when a structure is described as being "on or above" or "under or below" another structure, such description should be interpreted to include the case where the structures are in contact with each other and the case where a third structure is provided therebetween. The dimensions and thicknesses of each element shown in the drawings are only given for convenience of description, and unless otherwise specified, the embodiments of the present disclosure are not limited thereto.

[0211] As can be fully understood by those skilled in the art, the features of various embodiments of the present disclosure can be partially or wholly coupled or combined with each other, and can be interoperated with each other in various ways and be technically driven. The embodiments of the present disclosure can be executed independently of each other, or can be executed together in a mutually dependent relationship.

[0212] In the present disclosure, examples of a display device may include a narrow display device 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 a display device may include a kit (or a complete set of equipment) or a complete electronic device that is a complete product (or a final product) including an LCM or an OLED module, such as a notebook computer, a TV, a computer monitor, a component including an automotive device or other types of devices for a vehicle, or a mobile electronic device such as a smart phone or an electronic tablet.

[0213] Thus, in the present disclosure, examples of the display device may include the display device itself in a narrow sense such as an LCM or an OLED module, and a set-top device that is a final consumer device or application product including the LCM or the OLED module.

[0214] In some embodiments, an LCM or an OLED module including a display panel and a driver may be referred to as a display device in a narrow sense, and an electronic device that is a final product including the LCM or the OLED module may be referred to as a set-top device. For example, the display device in a narrow sense may include a display panel such as an LCD or an OLED, and a source printed circuit board (PCB) that is a controller for driving the display panel. The set-top device may further include a set-top PCB, which is a set-top controller electrically connected to the source PCB to control the set-top device as a whole.

[0215] The display panel applied to this embodiment may use all types of display panels that are vibrated by the sound generating device according to this embodiment to output sound, such as a liquid crystal display panel, an organic light emitting diode (OLED) display panel, and an electroluminescent display panel, 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.

[0216] 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 disposed in a plurality of pixel regions defined by the intersections of the gate lines and the data lines. In addition, the display panel may include: an array substrate including thin film transistors (TFTs) that are 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 disposed between the array substrate and the upper substrate.

[0217] 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 disposed in a plurality of pixel regions defined by the intersections of the gate lines and the data lines. In addition, the display panel may include: an array substrate including TFTs that are elements for selectively applying a voltage to each pixel; an organic light emitting device layer disposed on the array substrate; and a package substrate disposed on the array substrate to cover the organic light emitting device layer. The package substrate may protect the TFTs 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 disposed 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 disposed on the array substrate may include micro light emitting diodes.

[0218] In the present disclosure, a display panel can be applied to a vehicle as a user interface module, for example, a central control panel for an automobile. For example, the display panel can be disposed between passengers sitting on two front seats so as to transmit vibrations of the display panel to the interior of the vehicle. Accordingly, compared with a case where a speaker is disposed inside the vehicle, an audio experience in the vehicle is improved.

[0219] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. When adding reference numerals to elements of each drawing, although the same elements are shown in other drawings, the same reference numerals may denote the same elements. In addition, for ease of description, the scale of each element shown in the drawings is different from the actual scale, and thus is not limited to the scale shown in the drawings.

[0220] Figure 1 A display device according to an embodiment of the present disclosure is shown. Figure 2 is a cross-sectional view taken along Figure 1 the line I-I' shown.

[0221] Referring to Figure 1 and Figure 2 , a display device according to an embodiment of the present disclosure may include a display module 100, a rear cover 300, and at least one sound generating module 500.

[0222] The display module 100 may vibrate based on driving of at least one sound generating module 500 to directly output sound PVS (or panel vibration sound) in a front surface direction (or front area) FD while displaying an image. Alternatively, the display module 100 may vibrate based on driving of at least one sound generating module 500 to directly output the sound PVS to the front area FD in a state where no image is displayed. Accordingly, the display module 100 according to the present disclosure can display an image and can generate (or output) the sound PVS.

[0223] 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.

[0224] The display panel 110 may be implemented as all types of display panels, 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 may vibrate based on vibrations of the sound generating module 500 to directly output the sound PVS to the front area FD. Accordingly, the display panel 110 may be a diaphragm or a speaker that directly generates the sound PVS. For example, when the display module 100 generates the sound PVS, the display module 100 may be a diaphragm, a panel speaker, or a flat panel speaker that directly generates the sound PVS.

[0225] According to some embodiments of the present disclosure, the display panel 110 may include a pixel circuit disposed on a substrate (or a bottom plate), and a pixel array layer (or a 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 may 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.

[0226] In the top-emission type, the light generated from the pixel array layer may be output to the front region FD in front of the substrate of the display panel 110. In the bottom-emission type, the light generated from the pixel array layer may be output to the outside through the substrate, thereby displaying an image.

[0227] 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.

[0228] 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.

[0229] According to some embodiments, the functional film 130 may include an antireflection layer (or an antireflection film) for preventing reflection of external light, so as to enhance outdoor visibility and contrast with respect to the image displayed by the display panel 110. For example, the antireflection layer may include a circularly polarizing layer (or a circularly polarizing film), which prevents external light reflected by thin-film transistors (TFTs) and / or lines disposed on the pixel array layer of the display panel 110 from propagating to the outside.

[0230] According to some embodiments of the present disclosure, the functional film 130 may further include an optical path control layer (or an optical path control film) for controlling the light output path from the pixel array layer of the display panel 110 to the outside. The optical path control layer may include a stacked structure in which a high-refractive-index layer and a low-refractive-index layer are alternately stacked, and may change the path of the light incident from the pixel array layer to minimize the color shift phenomenon based on the viewing angle. For example, the low-refractive-index layer may be disposed on the uppermost layer of the optical path control layer.

[0231] The display module 100 according to some embodiments of the present disclosure may further include a touch electrode unit for a user interface using user touch. The touch electrode unit may be disposed 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 type touch electrode or a self-capacitance type touch electrode.

[0232] The rear cover 300 may be disposed on the rear surface of the display module 100. The rear cover 300 may support or fix the sound generating module 500.

[0233] According to some embodiments of the present disclosure, the rear cover 300 may cover the rear surfaces of the display module 100 and the sound generating module 500. The rear cover 300 may be referred to as a support member, a housing, a system cover, a fixing cover, a rear 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.

[0234] According to some embodiments of the present disclosure, the rear cover 300 may include a first rear cover 310 and a second rear cover 350.

[0235] The first rear cover 310 may be disposed 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 rear cover 310 may be spaced apart from the last surface of the display module 100 with a gap space GS therebetween. The first rear cover 310 may support or fix the sound generating module 500. The first rear cover 310 may protect the rear surface of the display panel 110 from external impact. In addition, the first rear cover 310 may perform the function of a heat sink for dissipating heat generated in the display module 100.

[0236] According to some embodiments of the present disclosure, the first rear cover 310 may be a plate member that covers the last surface of the display module 100 (e.g., the entire rear surface of the display panel 110). For example, the edge or corner of the first rear cover 310 may have an inclined shape or a curved shape through a chamfering process or a rounding process.

[0237] According to some embodiments of the present disclosure, the first rear cover 310 according to the embodiments of the present disclosure may include a glass material, a metal material, or a plastic material. For example, the first rear cover 310 including a glass material may include one of sapphire glass and gorilla glass or a laminated structure (or a bonded structure) thereof, but is not limited thereto. For example, the first rear cover 310 including a metal material may include one material 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 laminated) structure thereof.

[0238] The second rear cover 350 may be disposed on the rear surface of the first rear cover 310 and may cover the rear surface of the first rear cover 310. According to some embodiments of the present disclosure, the second rear cover 350 may be a plate member that covers the entire rear surface of the first rear cover 310. For example, the edges or corners of the second rear cover 350 may have an inclined shape or a curved shape through a chamfering process or a rounding process.

[0239] According to some embodiments of the present disclosure, the second rear 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 rear cover 310. For example, the second rear cover 350 may be formed of a glass material, and the first rear 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 may be improved based on the second rear cover 350 disposed on the last surface and including a glass material, and the rear surface of the display device may use the first rear cover 310 including a metal material as a mirror surface.

[0240] According to some embodiments of the present disclosure, the second rear cover 350 according to the embodiments of the present disclosure may have a thickness equal to or thinner than that of the first rear cover 310 within the manufacturing process error range. For example, in order to more stably support the sound generation module 500 and reduce the weight of the display device, the first rear cover 310 may have a thickness thicker than that of the second rear cover 350.

[0241] According to some embodiments of the present disclosure, the first rear cover 310 and the second rear cover 350 may be coupled or connected to each other through 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 adhesive foam pad, and may have elasticity for absorbing shock.

[0242] According to some embodiments of the present disclosure, the cover coupling member 330 may be disposed in the entire area between the first rear cover 310 and the second rear cover 350.

[0243] According to some embodiments, the cover coupling member 330 may be disposed in a mesh structure including an air gap between the first rear cover 310 and the second rear cover 350. For example, a part of the air gap between the first rear cover 310 and the second rear cover 350 may be used as an arrangement area for a signal transmission member or a cable connected to the sound generation module 500.

[0244] At least one sound generation module 500 may use the display module 100 as a diaphragm to generate sound PVS. For example, at least one sound generation module 500 may use the display panel 110 as a diaphragm to generate sound PVS.

[0245] A display device according to some embodiments of the present disclosure may include one sound generating module disposed at a rear central portion (or central region) of the display module 100. For example, the one sound generating module may vibrate the rear central portion of the display module 100 to generate a sound PVS based on the vibration of the display module 100.

[0246] 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. Relative to the rear central portion of the display module 100, 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. For example, the first sound generating module 500-1 may vibrate a first rear region of the display module 100 to generate a sound PVS based on the vibration of the first region of the display module 100. The second sound generating module 500-2 may vibrate a second rear region of the display module 100 to generate a 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 a two-channel stereo based on left and right sound separation by 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 sound, and the second sound generating module 500-2 may be configured to output right sound.

[0247] 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 rear cover 300, and may vibrate the display module 100 to generate a sound PVS. The rear surface of at least one sound generating module 500 may be covered by the rear cover 300, so that it may be hidden and not directly exposed on the outermost rear surface of the display device. Therefore, since the rear surface of at least one sound generating module 500 is covered by the rear cover 300, the display device according to the embodiments of the present disclosure may have a simple back design, in which a part or the rear surface of at least one sound generating module 500 is not exposed or not visible to the user's eyes, thereby improving the rear appearance design.

[0248] At least one sound generating module 500 according to some embodiments of the present disclosure may be a single structure or a single body, in which a module structure 510 provided at the rear cover 300 and a 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 body through a modularization process (or an assembly process) instead of an assembly process performed on the display device, and then, at least one sound generating module 500 may be installed or disposed in a gap space GS between the display module 100 and the rear cover 300 through a relatively simple component mounting (or positioning) process in the assembly process performed on the display device. Therefore, in the display device according to the embodiments of the present disclosure, the assembly performance of at least one sound generating module 500 can be improved during the process of assembling the module, thereby improving the production yield.

[0249] At least one sound generating module 500 according to the embodiments of the present disclosure may directly or indirectly vibrate the display module 100. For example, 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, at least one sound generating module 500 may indirectly vibrate the display panel 110 by using a vibration transmission member directly connected to the display panel 110. For example, the vibration transmission member may be implemented in the corresponding sound generating module 500 or the display module 100. For example, the vibration transmission member implemented in at least one sound generating module 500 may be a vibration transmission plate (or a vibration transmission sheet) that contacts (or is coupled to) the display module 100. In addition, the vibration transmission 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 transmission plate (or a heat dissipation plate) coupled to (or attached to) the rear surface of the display panel 110.

[0250] The display device according to the embodiments of the present disclosure may further include an intermediate frame 700.

[0251] The intermediate frame 700 may be disposed between the rear edge of the display module 100 and the front edge of the rear cover 300. The intermediate frame 700 may support the edges (or peripheries) of each of the display module 100 and the rear cover 300, and may surround the side surfaces of each of the display module 100 and the rear cover 300. The intermediate frame 700 may provide a gap space GS between the display module 100 and the rear 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.

[0252] According to some embodiments of the present disclosure, the intermediate frame 700 may be connected or coupled to the rear edge (or rear periphery) of the display module 100 by a first adhesive member 7011, and may be connected or coupled to the front edge (or front periphery) of the rear cover 300 by 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 term is not limited thereto. In addition, the intermediate frame 700 may be referred to as an intermediate box, an intermediate cover, or an intermediate chassis, but the term is not limited thereto.

[0253] According to some embodiments of the present disclosure, the intermediate frame 700 may include a metal material or a plastic material. For example, the intermediate 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.

[0254] The intermediate frame 700 according to some embodiments of the present disclosure may include a support portion 7110 and a side wall portion 7130. The support portion 7110 may be a first part, and the side wall portion 7130 may be a second part, but the terms are not limited thereto.

[0255] 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 rear cover 300, so as to provide a clearance space GS between the display module 100 and the rear cover 300. The front surface of the support portion 7110 may be coupled to the rear edge of the display module 100 by a first adhesive member 7011, and the rear surface of the support portion 7110 may be coupled to the front edge of the rear cover 300 by a second adhesive member 7013. The support portion 7110 may have a thickness (or height) corresponding to the total 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 rear cover 300, the thickness of the first adhesive member 7011, and the thickness of the second adhesive member 7013.

[0256] According to some embodiments of the present disclosure, the support portion 7110 may have a single square (quadrilateral) photo 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.

[0257] 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 adhesive foam pad, but is not limited thereto.

[0258] 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.

[0259] The side wall portion 7130 may be perpendicularly coupled to the outer surface of the support portion 7110 parallel to the thickness direction Z of the display device. The side wall portion 7130 may surround the entire outer surface (or outer side wall) of the display module 100 and the outer surface (or outer side wall) of the rear cover 300, thereby protecting the outer surfaces of each of the display module 100 and the rear cover 300 and improving the appearance design of the side surface of the display device. The intermediate frame 700 according to some embodiments of the present disclosure may be coupled to each other such that the support portion 7110 and the side wall portion 7130 form a single body, thereby obtaining a photo frame structure having an "┣"-shaped single-sided structure.

[0260] A display device according to an embodiment of the present disclosure may include an adhesive member instead of the intermediate frame 700.

[0261] The adhesive member may be located between the rear edge of the display module 100 and the front edge of the rear cover 300, and may provide a gap space GS between the display module 100 and the rear cover 300. The adhesive member may have a thickness (or height) corresponding to the 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 rear cover 300. The adhesive member may perform the same function as the support portion 7110 of the intermediate frame 700.

[0262] When the display device includes an adhesive member instead of the intermediate frame 700, the rear 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 rear cover 300, and the outer surface (or outer side wall) of the adhesive member.

[0263] The sidewall covering portion may extend from an end of the second rear cover 350 and may be vertically bent 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 an end of any member is bent into a bent shape to overlap each other or be spaced apart parallel to each other. For example, the sidewall covering portion having a hemming structure may include a first sidewall and a second sidewall. The first sidewall extends from an end of the second rear cover 350 and is vertically bent to be parallel to the thickness direction Z of the display device. The second sidewall extends from an end of the first sidewall and is bent to be parallel to the first sidewall. The second sidewall may be located between the outer surface of the display module 100 and the first sidewall. 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.

[0264] In a display device according to an embodiment of the present disclosure, the display module 100 may further include a heat dissipation member 150.

[0265] 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 to overlap the sound generating module 500 and may be coupled or connected to the vibration device 530 of the sound generating module 500. The heat dissipation member 150 may be disposed on the rear surface of the display module 100 to overlap the vibration device 530 and may diffuse the heat generated when driving the vibration device 530 toward the display module 100, thereby preventing a performance degradation of the vibration device 530 caused by heat. In addition, the heat dissipation member 150 may have a wider size than the central portion of the vibration device 530 with respect to the vibration device 530 and may diffuse the heat generated when driving the vibration device 530 to a wide area, thereby preventing the heat from being concentrated and transferred to a local area of the display module 100 that overlaps the sound generating module 500. Accordingly, local brightness non-uniformity of the display module 100 may be prevented or minimized.

[0266] According to some embodiments of the present disclosure, the heat dissipation member 150 may include one or an alloy of aluminum (Al), copper (Cu), silver (Ag), and magnesium (Mg), or may include a metallic material having high thermal conductivity like its alloy, 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.

[0267] Accordingly, the display device according to an embodiment of the present disclosure can output the sound PVS to the front region FD based on the vibration of the display module 100 (e.g., the display panel 110) caused by the vibration of the sound generation module 500, thereby enhancing the immersive experience of a viewer who views an image displayed by the display device.

[0268] In addition, in the display device according to an 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 the design and component layout of the set-top device.

[0269] In addition, since the sound generation module 500 is disposed in the gap space GS between the display module 100 and the rear cover 300, the rear surface of the sound generation module 500 can be covered by the rear cover 300. Accordingly, the display device according to an embodiment of the present disclosure can have a simple rear design in which a part or the rear surface of the sound generation module 500 is not exposed or not visible to a user, thereby improving the rear appearance design of the display device.

[0270] In addition, in the display device according to an embodiment of the present disclosure, the module structure 510 and the vibration device 530 of the sound generation module 500 can be modularized into one element and can be installed in the gap space GS between the display module 100 and the rear cover 300 through a relatively simple component mounting process. Accordingly, the assembly performance of the sound generation module 500 can be improved during the assembly process performed on the display device, thereby improving the production yield.

[0271] Figures 3A to 3E The sound generation module according to an embodiment of the present disclosure is shown.

[0272] Referring to Figures 2 to 3E , the sound generation module 500 according to an embodiment of the present disclosure can include a module structure 510 and a vibration device 530.

[0273] The module structure 510 can be disposed at the rear cover 300. For example, the module structure 510 can be disposed at the rear cover 300 and can fix or support the vibration device 530. According to some embodiments of the present disclosure, the module structure 510 can be a metal plate including a metal material and having a plate shape. The module structure 510 can 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.

[0274] The module structure 510 may be disposed on or fixed to the rear cover 300 by using the first member 410 (or module fixing member). The rear surface of the module structure 510 may be covered by the rear cover 300, and thus may be hidden without being directly exposed at the outermost rear surface of the display device. For example, the rear surface of the module structure 510 may be completely covered by the rear cover 300, and thus may be hidden without being directly exposed at the outermost rear surface of the display device.

[0275] According to some embodiments of the present disclosure, the first member 410 may be a double-sided adhesive member between the module structure 510 and the rear cover 300. The double-sided adhesive member may be a double-sided tape or a double-sided 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 rear 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 rear cover 300 (e.g., the front surface of the first rear 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 rear cover 310 in a state where the lower protective sheet is peeled off therefrom.

[0276] According to some embodiments of the present disclosure, the first member 410 may be coupled (or modularized) to the last surface of the sound generation module 500 modularized as one element, so as to facilitate the assembly between the sound generation 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.

[0277] According to some embodiments of the present disclosure, the double-sided adhesive member as the first member 410 may further include a heat transfer material. The heat transfer material may rapidly transfer the heat generated in the sound generation module 500 to the rear cover 300, and thus may dissipate the heat of the sound generation module 500 toward the rear cover 300, thereby preventing or minimizing the local brightness non-uniformity of the display module 100 caused by the heat generated during the driving of the sound generation module 500 being locally transferred to the area of the display module 100 overlapping with the sound generation 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, the double-sided adhesive member including the heat transfer material may be referred to as a heat transfer tape or a heat dissipation tape, but the term is not limited thereto.

[0278] The vibration device 530 may be disposed at the module structure 510 and may vibrate the display module 100. For example, the vibration device 530 may be disposed 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 disposed with or fixed to the module structure 510.

[0279] 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 by using the 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.

[0280] 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. For example, the vibration device 530 may be a vibration device including a voice coil, but the term is not limited thereto.

[0281] The base plate 531 may be disposed on or fixed to the module structure 510 and may be the main body of the vibration device 530. The base plate 531 may support each of the magnet 532, the center pole 533, and the frame 536. The base plate 531 may include a magnetic metal material such as iron (Fe). The base plate 531 may be referred to as a lower plate, a chassis, or a yoke, but the term is not limited thereto.

[0282] The base plate 531 may include a groove portion for accommodating the magnet 532 and the bobbin 534. For example, the groove portion may be recessed from the upper surface of the base plate 531 and may be formed in a circular shape.

[0283] By using the module integration member 520, the base plate 531 may be integrally disposed with the module structure 510 or disposed at the module structure 510.

[0284] The module integration member 520 may be an adhesive member. The adhesive member may be disposed between an extension portion (or fixing portion) 531a of the base plate 531 and the module structure 510, and thus, the base plate 531 may be disposed at the module structure 510. The module integration member 520 including the adhesive member may be an adhesive or a double-sided tape, but is not limited thereto.

[0285] According to another embodiment of the present disclosure, the module integration member 520 may include a plurality of screws. The plurality of screws may pass through the extension portion 531a of the base plate 531 and may be fastened to the module structure 510, and thus, the base plate 531 may be disposed at the module structure 510.

[0286] According to another embodiment of the present disclosure, the module integration member 520 may include a bolt and a nut. The nut may be disposed or fixed to the module structure 510 that overlaps with the extension 531a of the bottom plate 531. The bolt may pass through the extension 531a of the bottom 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 disposed at the module structure 510, but is not limited thereto. The self-tightening nut may be a nut.

[0287] 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.

[0288] 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 a 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 a generally smaller size and low leakage magnetic 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.

[0289] According to some embodiments of the present disclosure, the magnet 532 may be inserted 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 or accommodated in the bobbin 534. According to some embodiments of the present disclosure, the magnet 532 may be implemented with a sintered magnet such as barium ferrite, and the material of the magnet 532 may include one or more of Fe2O3, BaCO3, neodymium magnets, strontium ferrite (Fe 12 O 19 Sr) with improved magnetic components, and alloy cast magnets 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.

[0290] The spool 534 according to some embodiments of the present disclosure may be disposed on the base plate 531 and surround the magnet 532. The spool 534 may have a circular or oval shape, but is not limited thereto. The oval may be an ellipse, a rectangle 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 spool 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 spool 534 having an oval shape may improve the sound in the high-pitched sound band better than the circular shape, and may reduce the generation of heat caused by vibration, and thus may have excellent heat dissipation characteristics.

[0291] The coil 535 according to some embodiments of the present disclosure may be wound around the outer circumferential surface of the spool 534, and a sound generating current (or voice current) may be provided thereto from the outside. The coil 535 may move down or up together with the spool 534. The coil 535 may be referred to as a voice coil. When a current is applied to the coil 535, the entire part of the spool 534 may move up and down according to Fleming's left hand rule based on the applied magnetic field generated around the coil 535 and the external magnetic field generated around the magnet 532, and sound PVS or sound waves may be generated based on the vibration of the display module 100 caused by the vertical movement (or vibration) of the spool 534.

[0292] According to an embodiment of the present disclosure, when the coil 535 is wound around the outer circumferential surface of the spool 534, the heat generated in the coil 535 may be transferred to the spool 534, and the coil 535 may include a material having relatively good heat dissipation characteristics to reduce image quality defects affecting the display panel 110 due to the heat of the spool 534. In addition, since the spool 534 vibrates up and down, horizontal vibration may occur due to the vertical vibration, and the horizontal vibration of the spool 534 may be affected by the weight of the spool 534. The weight of the spool 534 may be affected by the weight of the coil 535. Therefore, when the weight of the coil 535 is reduced, the horizontal vibration of the spool 534 may be reduced. Therefore, considering the heat transferred to the spool 534 and the horizontal vibration of the spool 534, the coil 535 may have relatively good heat dissipation characteristics because its thermal conductivity is better than that of copper, which is a general coil material, and the coil 535 may include an Al material having relatively good heat dissipation characteristics and relatively light weight compared to copper.

[0293] In addition, in aluminum, since oxides are formed in air, welding may not be easy when manufacturing the vibration device 530. Therefore, the coil 535 according to an 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 an aluminum-clad copper wire covered with copper. The metal covering layer may be formed as a thin film type outside the first metal layer, and thus, may not have a great impact on the weight increase of the coil 535. Therefore, compared with a coil including only Cu or a Cu wire, the weight of the coil 535 according to an embodiment of the present disclosure may be reduced by about 60%.

[0294] According to some embodiments of the present disclosure, the bobbin 534 may include a structure including a material obtained by processing pulp or paper, Al or Mg or an alloy thereof, or a synthetic resin such as polyimide. For example, the bobbin 534 may be implemented with a polyimide film having relatively good heat dissipation characteristics and relatively light weight to prevent image quality defects of the display panel 110 caused by heat generated in the coil 535.

[0295] The polyimide film may have physical properties that are unchanged in a wide temperature range from -273°C to -400°C, and may have heat resistance, electrical insulation, flexibility, and non-flammability. In addition, since the polyimide film has good thermal strength and mechanical strength, the polyimide film may enhance the reliability of the bobbin 534 and may reduce the generation of heat caused by the vibration of the bobbin 534 based on excellent heat dissipation characteristics. For example, the polyimide film may be KAPTON and may be a condensate of pyromellitic dianhydride and 4,4'-oxydianiline, but is not limited thereto.

[0296] The center pole 533 may be received or inserted into the bobbin 534 and may guide the ascent or descent of the bobbin 534. For example, since the center pole 533 is received or inserted into 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 a lifting guide or a pole piece, but the term is not limited thereto.

[0297] The frame 536 may be provided at the front edge (or front peripheral edge) 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 the shape 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 the shape of the bobbin 534.

[0298] The damper 537 can be provided or connected between the frame 536 and the magnetic circuit unit. For example, the damper 537 can be arranged or connected between the frame 536 and the bobbin 534. The damper 537 can be referred to as a spider, a suspension, or an edge member, but the term is not limited thereto.

[0299] One end or a part of the damper 537 according to some embodiments of the present disclosure can be connected to the frame 536, and the other end or another part of the damper 537 can be connected to the upper outer surface of the bobbin 534. The damper 537 can have a corrugated structure between its one end and the other end, and can contract and relax based on the vertical movement of the bobbin 534 to control the vibration of the bobbin 534. The damper 537 can be connected between the bobbin 534 and the frame 536, and can use the restoring force to limit the vibration distance of the bobbin 534. For example, when the bobbin 534 vibrates a certain distance or more or vibrates a certain distance or less, the bobbin 534 can return to the original position by the restoring force of the damper 537.

[0300] Since the vibration device 530 is provided between the display module 100 and the rear cover 300, the vibration device 530 should have a relatively thin thickness in order to reduce the thickness of the display device more thinly or make the display device thinner. Thus, 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 the reduction in 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 provided near the bobbin 534 is wide. When the area of the damper 537 is enlarged, the inventors have recognized that the space for arranging the line for applying current to the coil 535 becomes narrow, resulting in interference between the line and the damper 537. Therefore, through various experiments, the inventors have configured the damper 537 formed of a conductor and performing the function of the line.

[0301] The damper 537 according to some embodiments of the present disclosure can include a metal material electrically connected to the coil 535. For example, the damper 537 can be formed of stainless steel or copper (Cu), but is not limited thereto.

[0302] The vibration device 530 according to some embodiments of the present disclosure can further include a bobbin protection member 538.

[0303] The spool protection member 538 may be disposed on the front surface (or front end portion) of the spool 534, and may transfer the lifting motion (or vibration) of the spool 534 to the rear surface of the display module 100. The spool protection member 538 according to some embodiments of the present disclosure may have an annular shape disposed on the front surface of the spool 534, a disk shape covering the entire front surface of the spool 534, or a cap shape surrounding the front surface and the upper outer surface of the spool 534, but the shape is not limited thereto. For example, the spool protection member 538 may be referred to as a spool ring, but the term is not limited thereto.

[0304] The sound generating module 500 according to an embodiment of the present disclosure may further include a connection member 550.

[0305] The connection member 550 may be disposed between the module structure 510 and the display module 100. The connection member 550 according to some embodiments of the present disclosure may be disposed 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 connection member 550 may be a double-sided tape or a double-sided adhesive foam tape, but is not limited thereto. The connection member 550 may provide a vibration space around 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 speaker, a sound part, a resonance box, or a resonance part, but the term is not limited thereto.

[0306] The sound generating module 500 according to an embodiment of the present disclosure may further include a vibration transfer member 570.

[0307] The vibration transfer 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.

[0308] According to some embodiments of the present disclosure, the rear edge portion or rear peripheral portion of the vibration transfer member 570 may be connected or coupled to the connection member 550, and the rear central portion of the vibration transfer member 570 may be coupled to the front surface of the spool 534 of the vibration device 530, or may be coupled to the spool protection member 538 of the vibration device 530.

[0309] According to some embodiments of the present disclosure, the vibration transmission member 570 may be formed of one or more materials among 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 among Al, zinc (Zn), and manganese (Mn). The Mg alloy may be the lightest material among the metallic materials that can be used as a diaphragm of a speaker, may have relatively high non-rigidity (stiffness / specific gravity), and relatively high vibration damping ability (ability to absorb and gradually reduce vibration), and may have good dimensional stability against temperature change and the passage of time.

[0310] According to some embodiments of the present disclosure, the front surface of the vibration transmission member 570 may be coupled or connected to the rear surface of the display module 100 using the second member 430 (or module bonding member).

[0311] The second member 430 may be a double-sided bonding member between the display module 100 and the vibration transmission member 570. The double-sided bonding 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 second member 430 may be disposed 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 or coupled to the front surface of the vibration transmission member 570. For example, one surface of the second member 430 may be disposed or fixed to the rear surface of the display module 100 in a state where the upper protective sheet is peeled off.

[0312] According to some embodiments of the present disclosure, in order to facilitate the assembly between the sound generation module 500 and the display module 100, the second member 430 may be coupled (or modularized) to the uppermost surface of the sound generation module 500 that 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 release sheet or a top liner, but the term is not limited thereto.

[0313] For example, all of the vibration transmission member 570 and the second member 430 may be omitted. For example, the sound generation module 500 may include an upper protective sheet that is coupled or connected to each of the connection member 550 and the vibration device 530. The upper protective sheet may be coupled or connected to each of the connection member 550 and the vibration device 530 to cover the entire front surface of the sound generation module 500. Therefore, in the transfer process after the modularization process of the sound generation module 500 that is modularized into one element, each of the vibration device 530 and the connection member 550 of the sound generation module 500 can be prevented from being exposed, and particles such as dust can be prevented from penetrating into the sound generation module 500. The upper protective sheet may be peeled off from the sound generation module 500 immediately before the assembly process between the sound generation module 500 and the display module 100.

[0314] Therefore, the sound generation module 500 according to an embodiment of the present disclosure can be disposed between the display module 100 and the rear 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 diaphragm, 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.

[0315] Referring to Figure 3B and Figure 3C , the bonding member 522 can be disposed between the vibration device 530 and the module structure 510. The bonding member 522 can include one or more of a double-sided tape, a double-sided foam tape, a double-sided adhesive pad, a double-sided foam adhesive pad, and a bonding member, but is not limited thereto. When the bonding member 522 is provided, compared with screws or nuts and bolts, the assembly process can be simplified 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 that given above with reference to Figure 3A Therefore, its description is omitted.

[0316] Referring to Figure 3B , the vibration device 530 can be asymmetrically disposed. When the vibration device 530 is asymmetrically disposed, the dip phenomenon at a specific frequency can be reduced. For example, when standing waves appear in the upper, lower, left, and right portions relative to the vibration device 530, the dip phenomenon may occur in the upper, lower, left, and right portions. However, when the vibration device 530 is asymmetrically disposed, the phenomenon that standing waves simultaneously appear in the upper, lower, left, and right portions can be reduced. Therefore, the dip phenomenon can be reduced, and thus the sound characteristics can be further enhanced.

[0317] Referring to Figure 3D and Figure 3E , the rear cover 300 can include a first rear cover 310 and a second rear cover 350. The description of the first rear cover 310 and the second rear cover 350 is the same as that given above with reference to Figure 2 Therefore, its description is omitted.

[0318] Referring to Figure 3D, the vibration device 530 can be accommodated in the first rear cover 310. For example, the vibration device 530 can be disposed at the removal portion of the first rear cover 310. The first rear cover 310 can be attached to the vibration device 530 through the adhesive member 522. The adhesive member 522 can be disposed between the vibration device 530 and the second rear cover 350. As another example, the adhesive member 522 can also be disposed between the vibration device 530 and the first rear cover 310. For example, the adhesive member 522 can also be disposed between the extension portion 531a of the bottom plate 531 and the first rear cover 310. The adhesive member 522 can include one or more of a double-sided tape, a double-sided foam tape, a double-sided adhesive pad, a double-sided foam adhesive pad, and a bonding member, but is not limited thereto. A part of the first rear cover 310 can be removed, and the vibration device 530 can be disposed at the removal area of the first rear cover 310. Therefore, the thickness of the vibration device 530 can be reduced, thereby reducing the thickness of the display device. In addition, when the vibration device 530 is disposed adjacent to the first rear cover 310 and / or the second rear cover 350, abnormal vibration may occur when the vibration device 530 vibrates. Therefore, the vibration device 530 can be spaced apart from the first rear cover 310 and / or the second rear cover 350 by a certain interval or distance D. For example, the vibration device 530 can be spaced apart from the first rear cover 310 and / or the second rear cover 350 by this interval or distance D. For example, this interval or distance D can be 1 mm or more, but is not limited thereto.

[0319] Referring to Figure 3E , the vibration device 530 can be accommodated between the first rear cover 310 and the second rear cover 350. For example, the bottom plate 531 of the vibration device 530 can have an exposed surface. The bottom plate 531 of the vibration device 530 can be disposed between the first rear cover 310 and the second rear cover 350. The bottom plate 531 of the vibration device 530 can be configured to penetrate the first rear cover 310 and the second rear cover 350. The adhesive member 522 can be disposed between the vibration device 530 and the first rear cover 310. For example, the adhesive member 522 can be disposed on the extension portion 531a of the bottom plate 531 and one side of the first rear cover 310. The adhesive member 522 can include one or more of a double-sided tape, a double-sided foam tape, a double-sided adhesive pad, a double-sided foam adhesive pad, and a bonding member, but is not limited thereto. 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. In addition, when the vibration device 530 is disposed adjacent to the first rear cover 310 and the second rear cover 350, abnormal vibration may occur when the vibration device 530 vibrates. Therefore, the vibration device 530 can be spaced apart from the first rear cover 310 and the second rear cover 350 by a certain interval or distance D. For example, the vibration device 530 can be spaced apart from the first rear cover 310 and the second rear cover 350 by this interval or distance D. For example, this interval or distance D can be 1 mm or more, but is not limited thereto.

[0320] Figure 4 shows Figures 3A to 3E the connection member shown.

[0321] Referring to Figures 3A to 3E and Figure 4 According to some embodiments of the present disclosure, the connection member 550 may include a first connection portion 551 to a fourth connection portion 554. The first connection portion 551 to the fourth connection portion 554 may be a first connection portion to a fourth coupling portion, respectively, but these terms are not limited thereto.

[0322] Each of the first connection portion 551 to the fourth connection portion 554 may have a linear shape having a certain width and length, and may be disposed between the module structure 510 and the vibration transmission member 570.

[0323] According to some embodiments of the present disclosure, regarding Figure 4 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 part of the first front edge portion and a part 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 part of the first front edge portion and another part of the second front edge portion.

[0324] The first connection portion 551 may be disposed at the first front edge portion of the module structure 510, and the second connection portion 552 may be disposed at the second front edge portion of the module structure 510. The third connection portion 553 may be disposed at the third front edge portion of the module structure 510, and the fourth connection portion 554 may be disposed at the fourth front edge portion of the module structure 510.

[0325] Each of the first connection portion 551 to the fourth connection portion 554 may have a structure separated from the corresponding corner portion of the module structure 510. For example, each of the first connection portion 551 to the fourth connection portion 554 may have a square (quadrilateral) strip shape that is not separated therefrom, and in this case, materials other than the connection member 550 in the raw materials for forming the connection member 550 may be wasted, resulting in an increase in material costs.

[0326] A part of each of the first connection portion 551 to the fourth connection portion 554 may be disposed to contact an adjacent connection portion among the first connection portion 551 to the fourth connection portion 554 at the corresponding corner portion of the module structure 510. Therefore, external leakage of sound waves generated in the vibration space defined by the connection member 550 can be minimized.

[0327] At least one of the first connection part 551 to the fourth connection part 554 may include a plurality of bending parts 553a and 554a facing the vibration device 530.

[0328] When the display module 100 vibrates by using the vibration device 530, the sound waves generated can radially spread from the center of the vibration generating device and can propagate. The sound waves can be referred to as progressive waves. The progressive waves can be reflected by the connection member 550 to generate reflected waves, and the reflected waves can propagate in a direction opposite to that of the progressive waves. The reflected waves are superimposed and interfere with the progressive waves, and do not travel, thereby generating standing waves that are stationary at specific positions. The standing waves reduce the sound pressure, thereby reducing the sound output characteristics. Therefore, the bending parts 553a and 554a can be provided in the connection member 550 to reduce the phenomenon of sound pressure reduction caused by the standing waves generated due to the interference between the reflected waves and the progressive waves. For example, the bending parts 553a and 554a can be provided at the positions where the levels of each of the progressive waves and the reflected waves are the highest, or in at least one of the connection parts 551 to 554 where the strongest sound waves reach. For example, the bending parts 553a and 554a can be provided on the extension line EL of the central part of the vibration device 530 to face the central part of the vibration device 530, thereby minimizing the phenomenon of the sound pressure being reduced by the standing waves.

[0329] According to some embodiments, the bending parts 553a and 554a can be provided in the third connection part 553 and the fourth connection part 554. In addition, the bending parts 553a and 55a can have a certain inclination angle θ with respect to the horizontal direction (or width direction) X of the display device. The inclination angle θ of each of the bending parts 553a and 554a according to some embodiments of the present disclosure can vary based on the degree to which the standing waves are suppressed, and can be set, for example, to vary within a range of 10 degrees to 30 degrees. For example, when the vibration device 530 outputs sound in the bass band or the output of the vibration device 530 is large, the bending parts 553a and 553b can have a relatively large inclination angle θ. For example, when the vibration device 530 outputs sound in the treble band or the output of the vibration device 530 is small, the bending parts 553a and 554a can have a relatively small inclination angle θ.

[0330] The third connecting portion 553 and the fourth connecting portion 554 may have a structure that is symmetric about the bending portions 553a and 554a in the left - right direction. The bending portions 553a and 554a may have an opening structure on the extension line EL of the central portion of the vibration device 530, but are not limited thereto, and may have a V - shaped closed structure. When the bending portions 553a and 554a have an opening structure on the extension line EL of the central portion of the vibration device 530, the material cost can be reduced compared to the closed structure. In addition, according to the sound characteristic experiment, when the bending portions 553a and 554a have an opening structure on the extension line EL of the central portion of the vibration device 530 and when the bending portions 553a and 554a have a closed structure on the extension line EL, the inventors have confirmed that the difference in sound characteristics is very small or there is no difference in sound characteristics.

[0331] In addition, the bending portions 553a and 554a can be applied to the first connecting portion 551 and the second connecting portion 552 in the same or similar manner.

[0332] At least one of the first connecting portion 551 to the fourth connecting portion 554 may include at least one protrusion 555 and 556 facing the vibration device 530. For example, at least one of the protrusions 555 and 556 may be provided in the first connecting portion 551 and the second connecting portion 552 respectively to face the central portion of the vibration device 530. At least one of the protrusions 555 and 556 can absorb (trap) reflected waves, and can reduce the floating or settling phenomenon caused by standing waves, thereby minimizing the phenomenon of sound pressure reduction.

[0333] Figure 5A and Figure 5B are diagrams for describing the damper structure of a vibration device according to an embodiment of the present disclosure.

[0334] Figure 5A shows a vibration device having a single - body type structure, and Figure 5B shows a vibration device having a double - body type structure. The double - body type structure may be referred to as a double - array structure. A vibration device according to the present disclosure may be configured as a double - array structure or a more - array structure, and for example, may be configured as a four - array structure or a six - array structure.

[0335] Referring to Figures 3A - 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 spool 534 and the frame 536 provided on the base plate 531.

[0336] The damper 537 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 a positive voice signal) and a second damper 537-2 that receives negative power (or a negative voice signal).

[0337] For example, the damper 537 can be vertically divided with respect to the width direction X. For example, with respect to a center line passing through the central portion of the spool 534 in the width direction X, the first damper 537-1 can be disposed above the center line, and the second damper 537-2 can be disposed below the center line. For example, the first damper 537-1 can be electrically connected to the first line terminal 530p, and the second damper 537-2 can be electrically connected to the second line terminal 530m. The line terminals can be referred to as line pads, but these terms are not limited thereto. For example, the first line terminal 530p can be a positive (+) terminal, and the second line terminal 530m can be a negative (-) terminal.

[0338] According to some embodiments of the present disclosure, each of the first damper 537-1 and the second damper 537-2 can include an inner portion 537a, an outer portion 537b, and a plurality of damping portions 537c.

[0339] The inner portion 537a can have a semi-circular (or oval) shape and can be coupled or connected to the spool 534. For example, the central portion of the inner portion 537a has a semi-circular (or oval) shape. The inner portions 537a of the first damper 537-1 and the second damper 537-2 can be spaced apart (or separated) from each other on the center line passing through the central portion of the spool 534 in the width direction X, so that they can be electrically disconnected from each other.

[0340] The outer portion 537b can have a semi-circular (or oval) shape to surround the inner portion 537a and can be disposed on or coupled to the frame 536. For example, the central portion of the outer portion 537b having a semi-circular (or oval) shape can be the same as the central portion of the spool 534. The outer portions 537b of the first damper 537-1 and the second damper 537-2 can be spaced apart (or separated) from each other on the center line passing through the central portion of the spool 534 in the width direction X, so that they can be electrically disconnected from each other.

[0341] Each of the plurality of damping portions 537c may be connected between the inner portion 537a and the outer portion 537b to have a certain interval or distance (or equal intervals). Each of the plurality of damping portions 537c according to some embodiments of the present disclosure may have an S-shaped or serrated shape. Each of the plurality of damping portions 537c may contract and relax based on the vertical movement of the inner portion 537a (which is based on the vertical movement of the spool 534) to control the vibration of the spool 534. For example, each of the plurality of damping portions 537c may have a length relatively longer than the shortest distance between the frame 536 and the spool 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 may be set to be long.

[0342] According to some embodiments of the present disclosure, one end or a portion of each of the plurality of damping portions 537c may be connected to the inner portion 537a. For example, the connection portion between one end or a portion of each of the plurality of damping portions 537c and the inner portion 537a may be rounded into a curved shape. Therefore, each of the damping portions 537c can be prevented from being torn by the vertical movement of the corresponding damping portion 537c.

[0343] Referring to Figures 3A - 3E and Figure 5B According to another embodiment of the present disclosure, the vibration device 530 may include two sub-vibration devices 530a and 530b disposed on the 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 this term is not limited thereto.

[0344] In the dual-body type vibration device 530, the dampers 537 of the two sub-vibration devices 530a and 530b may be connected in parallel with each other. The dampers 537 of each of the two sub-vibration devices 530a and 530b may be configured to act as signal lines or signal wirings. Therefore, it may include a first damper 537-1 that receives positive power (or a positive voice signal) and a second damper 537-2 that receives negative power (or a negative voice signal).

[0345] According to some embodiments of the present disclosure, the damper 537 of each of the two sub-vibration devices 530a and 530b may be vertically divided with respect to the width direction X. For example, with respect to the center line passing through the center portion of the spool 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.

[0346] 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 given above with reference to Figure 5A the description given, and thus, the repetitive description is omitted.

[0347] The first dampers 537-1 of the two sub-vibration devices 530a and 530b may be electrically connected to each other in the central region 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 region of the bottom plate 531. Accordingly, the dampers 537 of the two sub-vibration devices 530a and 530b may be connected in parallel with each other.

[0348] 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 may be electrically connected to an audio amplifier (or an audio processor) through a signal cable (or a signal transmission member). Accordingly, the position of each of the first line terminal 530p and the second line terminal 530m exposed at the bottom plate 531 may be changed to a corner of the bottom plate 531 to facilitate electrical connection to the signal cable.

[0349] A vibration device 530 according to another embodiment of the present disclosure may further include a first bracket 539a to a fourth bracket 539d.

[0350] Each of the first bracket 539a to the fourth bracket 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 the first side surface (or the first short side) of the bottom plate 531, and the second bracket 539b may be disposed on the second side surface (or the second short side) of the bottom plate 531. The third bracket 539c may be disposed on the third side surface (or the first long side) of the bottom plate 531, and the fourth bracket 539d may be disposed on the fourth side surface (or the second long side) of the bottom plate 531.

[0351] Each of the first bracket 539a to the fourth bracket 539d may be fixed to the module structure 510 through a module integration member 520, and thus, the bottom plate 531 may be disposed on or fixed to the module structure 510.

[0352] For example, each of the first bracket 539a to the fourth bracket 539d can be fixed to or disposed on the module structure 510 by using a module integration member 520 such as double-sided tape. For example, one surface of each of the first bracket 539a to the fourth bracket 539d facing the module structure 510 can be set to a flat surface structure to increase the bonding area with the double-sided tape.

[0353] As another example, each of the first bracket 539a to the fourth bracket 539d can be fixed to or disposed on the module structure 510 by using a module integration member 520 such as an adhesive (or bonding member). For example, one surface of each of the first bracket 539a to the fourth bracket 539d facing the module structure 510 can be set to a concavo-convex structure including a plurality of ribbed patterns RP for controlling the flow of the adhesive and preventing the adhesive from overflowing.

[0354] As another example, each of the first bracket 539a to the fourth bracket 539d can be fixed to or disposed on the module structure 510 by using a module integration member 520 such as a plurality of screws. For example, each of the first bracket 539a to the fourth bracket 539d facing the module structure 510 can include at least one hole SH through which at least one screw passes.

[0355] Each of the first bracket 539a to the fourth bracket 539d can basically include at least one hole SH, and for the compatibility of the modular process performed between the vibration device 530 and the module structure 510 by using the module integration member 520, one surface of each of the first bracket 539a to the fourth bracket 539d can include a flat surface structure or a concavo-convex structure.

[0356] Figure 6 A sound generating module according to another embodiment of the present disclosure is shown.

[0357] Figure 6 An embodiment of adding a heat dissipation structure to the Figures 3A - 3E shown sound generating module is shown. 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 hereinafter.

[0358] Refer to Figure 2 and Figure 6 , a sound generating module 500 according to another embodiment of the present disclosure can include a module structure 510 and a vibration device 530.

[0359] The module structure 510 may be the basic structure of the sound generating module 500 and may be disposed on or fixed to the rear cover 300 by using the first member 410. The module structure 510 may include a groove 510h that overlaps with the vibration device 530.

[0360] The groove 510h may be formed to vertically penetrate 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.

[0361] The size of the groove 510h according to an embodiment of the present disclosure may be smaller than the size 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 propagates toward the rear cover 300.

[0362] According to another embodiment of the present disclosure, the groove 510h may have a size capable of accommodating or inserting a part of the rear surface of the vibration device 530 therein. For example, the groove 510h may be a receiving hole that accommodates a part 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 propagates toward the rear cover 300. In addition, the groove 510h according to another embodiment of the present disclosure may reduce the distance between the rear surface of the vibration device 530 and the rear cover 300 to improve heat dissipation efficiency.

[0363] Except that the module structure 510 further includes the groove 510h, other structures are the same as those of the Figures 3A - 3E module structure shown, so its repeated description can be omitted.

[0364] The vibration device 530 may be integrally disposed with or disposed at the module structure 510 by using the module integration member 520 to overlap with the groove 510h of the module structure 510. 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 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.

[0365] The elements of the vibration device 530 other than the bottom plate 531 and the hollow portion 530h are the same as those of the Figures 3A - 3E vibration device shown, so their repeated description is omitted.

[0366] 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 the size 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.

[0367] According to another embodiment of the present disclosure, the rear surface of the bottom plate 531 may be inserted or received 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 greater than the size of the bottom plate 531, a part of the rear surface of the bottom plate 531 may be inserted or received 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 and may be disposed in the groove 510h of the module structure 510. Accordingly, the thickness of the sound generating module 500 may be reduced by the accommodation height (or depth) or the insertion height (or depth) at which the bottom plate 531 is received or inserted into the groove 510h of the module structure 510, so that the sound generating module may become thinner.

[0368] At least one of the extension portion 531a (or the brackets 539a to 539d) of the bottom plate 531 and the module integration member 520 may be implemented such that a part of the rear surface of the bottom plate 531 is received or inserted into the groove 510h of the module structure 510. For example, the extension portion 531a (or the brackets 539a to 539d) of the bottom plate 531 may have a relatively thin thickness or may extend from the upper surface of the bottom plate 531 to be maximally spaced apart from the rear surface of the bottom plate 531 such that a part of the rear surface of the bottom plate 531 is received or inserted into the groove 510h of the module structure 510. In addition, the thickness of the module integration member 520 may be adjusted within a range in which a certain part of the rear surface of the bottom plate 531 is received or inserted into the groove 510h of the module structure 510.

[0369] 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 due to the driving of the vibration device 530 is dissipated toward the rear cover 300, may increase the sound pressure based on the driving of the vibration device 530, and may reduce the weight of the vibration device 530. In addition, when the vibration space provided in the connection member 550 is sealed, the sound pressure generated due to the driving of the vibration device 530 may be insufficient due to the limited sealed space, but since the vibration space communicates with the outside through the hollow portion 530h, the sound pressure generated in the vibration space based on the driving of the vibration device 530 may increase.

[0370] According to some embodiments of the present disclosure, the vibration device 530 may further include a plurality of plate holes 531h disposed in the bottom plate 531 and overlapping with the grooves 510h of the module structure 510. The plurality of plate holes 531h may penetrate the bottom plate 531 in the vertical direction Z, so as to overlap with at least one of the spool 534 and the magnet 532. For example, the plate holes 531h overlapping with the magnet 532 may be blocked during the manufacturing process of the vibration device 530. Therefore, the plate holes 531h may be disposed in the bottom plate 531 overlapping with the spool 534. For example, each of the plurality of plate holes 531h may be radially disposed in the rear surface of the bottom plate 531, but is not limited thereto. The plate holes 531h may be referred to as ventilation holes, but this term is not limited thereto. The plurality of plate holes 531h may additionally dissipate the heat generated in the vibration device 530.

[0371] Therefore, the sound generating module 500 according to another embodiment of the present disclosure may include the grooves 510h disposed in the module structure 510, and the hollow portion 530h and the plate holes 531h disposed in the vibration device 530, so as to enhance the heat dissipation function and increase the sound pressure generated in the vibration space based on the driving of the vibration device 530.

[0372] Figure 7 Shows the covering Figure 6 The rear cover covering the rear surface of the sound generating module according to another embodiment of the present disclosure as shown.

[0373] Figure 7 An embodiment is shown in which a plurality of holes (or ventilation holes) are additionally provided in the rear cover overlapping with the sound generating module. Therefore, hereinafter, descriptions of the same elements will be briefly given or omitted except for the elements related to the plurality of holes.

[0374] Referring to Figure 2 、 Figure 6 and Figure 7 According to another embodiment of the present disclosure, the rear cover 300 may include a plurality of holes 300h overlapping with the sound generating module 500.

[0375] Each of the plurality of holes 300h may be disposed to vertically penetrate through the entire second rear cover 350 and the first rear cover 310 of the rear cover 300 in the thickness direction Z, and may overlap with the vibration device 530.

[0376] A plurality of holes 300h may be radially arranged to overlap with a 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 a certain interval or distance (or equal intervals) with respect to the central portion of the hollow portion 530h provided in the vibration device 530. For example, the plurality of holes 300h may be arranged at a certain interval on the circumferences of a plurality of concentric circles, and these concentric circles together with the hollow portion 530h provided in the vibration device 530 form a concentric shape.

[0377] 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 rear 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 generation module 500 or the hollow portion 530h provided in the vibration device 530, and thus, the simple back design of the display device is not reduced.

[0378] Figure 8 is along Figure 1 Another schematic cross-sectional view taken along the line I-I' shown, and shows a display device according to another embodiment of the present disclosure.

[0379] Referring to Figure 1 and Figure 8 , a display device according to another embodiment of the present disclosure may include one sound generation module 500 located between the display module 100 and the rear cover 300.

[0380] The display module 100 and the rear cover 300 are the same as the display module and the rear cover shown in Figure 2 and Figures 3A - 3E , so their repeated descriptions are omitted.

[0381] One sound generation module 500 may be configured by modularizing the Figure 2 and Figures 3A - 3E first sound generation module 500-1 and the second sound generation module 500-2 into one element.

[0382] According to some embodiments of the present disclosure, one sound generation module 500 may include a module structure 1510, a first vibration device 530-1, and a second vibration device 530-2.

[0383] 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 on the outermost rear surface of the display device. Except that Figure 2 and Figures 3A - 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 plate structure, the module structure 1510 is the same as the module structure shown in Figure 2 and Figures 3A - 3E so the repeated description thereof is omitted.

[0384] The first vibration device 530-1 can be disposed on or fixed to the first area of the module structure 1510 and can vibrate the display module 100 (for example, the first area (or the 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 on 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 at the central part of the first area of the module structure 1510, or can be disposed close to the edge or the peripheral part of the first area of the module structure 1510.

[0385] The second vibration device 530-2 can be disposed on or fixed to the second area of the module structure 1510 and can vibrate the display module 100 (for example, the second area (or the right area) of the display panel 110). For example, by using the module integration member 520, the second vibration device 530-2 can be disposed on or fixed to the second 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 second vibration device 530-2 can be disposed at the central part of the second area of the module structure 1510, or can be disposed close to the edge or the peripheral part of the second area of the module structure 1510. For example, the second vibration device 530-2 can be disposed symmetrically with the first vibration device 530-1 with respect to the central part of the module structure 1510.

[0386] Except that each of the first vibration device 530-1 and the second vibration device 530-2 is disposed as a single module structure 1510, each of the first vibration device 530-1 and the second vibration device 530-2 is the same as the vibration device shown in Figure 2 and Figures 3A - 3E so the repeated description thereof is omitted. In addition, each of the first vibration device 530-1 and the second vibration device 530-2 can have the single body type structure shown in Figure 5A but is not limited thereto, and can haveFigure 5B The twin - body type structure shown.

[0387] Figure 8 One sound generation module 500 shown is shown to include 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, stereo PVS with three channels or more channels may be output based on the vibration of each of the three or more vibration devices embedded in one sound generation module 500.

[0388] One sound generation module 500 may further include a connection member 550 and a partition member 560.

[0389] The connection member 550 may be disposed between the module structure 1510 and the display module 100. For example, the connection member 550 may be disposed between the 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 disposed on or fixed to the module structure 1510.

[0390] A partition member 560 may be disposed 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 region and the second region of the module structure 1510. For example, the partition member 560 may include a first partition portion 561 and a second partition portion 562 disposed in parallel in the central region between the first region and the second region of the module structure 1510. Based on the vibrations generated in each of the first region and the second region of the module structure 1510 in the display module 100 (for example, the first region and the second region of the display panel 110), the first partition portion 561 and the second partition portion 562 may reduce the influence on the sound characteristics caused by the resonance frequency difference of the medium - high - pitched sounds.

[0391] One sound generation module 500 may further include a vibration transmission member 1570 and a second member 430.

[0392] The vibration transmission member 1570 may be disposed on or coupled to each of the plurality of vibration devices 530 - 1 and 530 - 2, as well as the connection member 550 and the partition 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 (for example, the display panel 110). In addition to the vibration transmission member 1570 being additionally coupled to each of the plurality of vibration devices 530 - 1 and 530 - 2 and the partition member 560, the vibration transmission member 1570 and Figure 2 andFigures 3A - 3E is the same as the vibration device shown, and thus a repetitive description thereof will be omitted.

[0393] The second member 430 may be a double-sided adhesive member disposed between the display module 100 and the vibration transmission member 570. The double-sided adhesive member may be a double-sided tape or a double-sided foam tape, but is not limited thereto. The second member 430 is the same as Figures 3A - 3E the second member 430 shown, and thus, a repetitive description thereof will be omitted.

[0394] Accordingly, 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 may be further improved during the process of assembling the module, thereby improving the production yield of the display device.

[0395] Figure 9 shows Figures 3A - 3E the connection member and the partition member shown.

[0396] Referring to Figure 8 and Figure 9 , a connection member 550 according to an embodiment of the present disclosure may include first to fourth connection portions 1551 to 1554.

[0397] Each of the first to fourth connection portions 1551 to 1554 may be disposed between a front edge or a peripheral portion of the module structure 1510 and the display module 100, or may be disposed between a front edge or a peripheral portion of the module structure 1510 and the vibration transmission member 1570.

[0398] 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.

[0399] According to some embodiments of the present disclosure, for Figure 9 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 part of the first front edge portion and a part 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 part of the first front edge portion and another part of the second front edge portion.

[0400] The first connection part 1551 may be disposed at the first front edge part of the module structure 1510, and the second connection part 1552 may be disposed at the second front edge part of the module structure 1510. The third connection part 1553 may be disposed at the third front edge part of the module structure 1510, and the fourth connection part 1554 may be disposed at the fourth front edge part of the module structure 1510.

[0401] Each of the first connection part 1551 to the fourth connection part 1554 may have a structure separated from the corresponding corner part of the module structure 1510. For example, each of the first connection part 1551 to the fourth connection part 1554 may have a rectangular (quadrilateral) belt shape that is not separated from it, and in this case, materials other than the connection member 550 in the raw material for forming the connection member 550 may be wasted, resulting in an increase in material costs.

[0402] A part of each of the first connection part 1551 to the fourth connection part 1554 may be arranged to contact an adjacent connection part among the first connection part 1551 to the fourth connection part 1554 at the corresponding corner part of the module structure 1510. Therefore, external leakage of sound waves generated in the vibration space defined by the connection member 550 can be minimized.

[0403] At least one of the first connection part 1551 to the fourth connection part 1554 may include a plurality of bent parts 1553a and 1554a facing the first vibration device 530-1 and the second vibration device 530-2.

[0404] Each of the plurality of bent parts 1553a and 1554a may be disposed at the position where the level of each of the progressive wave and the reflected wave is the highest, or at least one connection part where the strongest sound wave among the first connection part 1551 to the fourth connection part 1554 arrives. For example, each of the plurality of bent parts 1553a and 1554a may be disposed on the extension line EL of the center part of each of the first vibration device 530-1 and the second vibration device 530-2 to face the center part of each of the first vibration device 530-1 and the second vibration device 530-2, thereby minimizing the phenomenon that the sound pressure is reduced by the standing wave.

[0405] According to some embodiments of the present disclosure, the plurality of bent parts 1553a and 1554a may be disposed in the third connection part 1553 and the fourth connection part 1554. In addition, the plurality of bent parts 1553a and 1554a may have a certain inclination angle θ with respect to the horizontal direction (or width direction) X of the display device. The inclination angle θ of each of the plurality of bent parts 1553a and 1554a according to some embodiments of the present disclosure may vary based on the degree of suppression of the standing wave, and may be set, for example, to vary within a range of 10 degrees to 30 degrees.

[0406] Each of the plurality of bent portions 1553a and 1554a may have an opening structure on the extension line EL of the central portion of the corresponding vibration device of the first vibration device 530-1 and the second vibration device 530-2, but is not limited thereto, and may have a V-shaped closed structure.

[0407] In addition, each of the plurality of bent portions 1553a and 1554a may be applied to at least one of the first connecting portion 1551 and the second connecting portion 1552 in the same or similar manner.

[0408] At least one of the first connecting portion 1551 to the fourth connecting portion 1554 may include at least one protrusion 555 and 556 facing the corresponding vibration device of the first vibration device 530-1 and the second vibration device 530-2. For example, at least one of the protrusions 555 and 556 may be respectively provided in the first connecting portion 1551 and the second connecting portion 1552 to face the central portion of the corresponding vibration device of the first vibration device 530-1 and the second vibration device 530-2. At least one of the protrusions 555 and 556 may absorb reflected waves, and may reduce the floating or settling phenomenon caused by standing waves, thereby minimizing the phenomenon of sound pressure reduction. At least one of the protrusions 555 and 556 may be referred to as the first protrusion, but the term is not limited thereto.

[0409] The partition member 560 may include a first partition portion 561 and a second partition portion 562 disposed in parallel in a central region between a first region and a second region of the module structure 1510.

[0410] Each of the first partition portion 561 and the second partition portion 562 may be disposed between the third connecting portion 1553 and the fourth connecting portion 1554 in parallel with each of the first connecting portion 1551 and the second connecting portion 1552. For example, each of the first partition portion 561 and the second partition portion 562 may have the same width as each of the first connecting portion 1551 to the fourth connecting portion 1554, but is not limited thereto.

[0411] An end portion of a part of each of the first partition portion 561 and the second partition portion 562 may approach the third connecting portion 1553 in a state of contacting or not contacting the third connecting portion 1553. An end portion of another part of each of the first partition portion 561 and the second partition portion 562 may approach the fourth connecting portion 1554 in a state of contacting or not contacting the fourth connecting portion 1554. The first partition portion 561 and the second partition portion 562 may reduce the influence on sound characteristics caused by the resonance frequency difference of medium and high pitch sounds based on vibrations generated in each of the first region and the second region of the module structure 1510 in the display module 100 (for example, the first region and the second region of the display panel 110).

[0412] The first partition portion 561 and the second partition portion 562 according to some embodiments of the present disclosure may each include at least one second protrusion 563 and 564, respectively.

[0413] According to some embodiments of the present disclosure, at least one second protrusion 563 in the first partition portion 561 may be disposed in the first partition portion 561 to face the central portion of the first vibration device 530-1. At least one second protrusion 564 in the second partition portion 562 may be disposed in the second partition portion 562 to face the central portion of the second vibration device 530-2. The second protrusions 563 and 564 may have the same or different lengths as the first protrusions 555 and 556. For example, the second protrusions 563 and 564 may have a longer length than the first protrusions 555 and 556. At least one of the protrusions 563 and 564 may absorb reflected waves and may reduce the floating or settling phenomenon caused by standing waves, thereby minimizing the phenomenon of sound pressure reduction.

[0414] Figure 10 is along Figure 1 Another cross-sectional view taken along the line I-I' shown. Figure 11 shows Figure 10 the back cover shown.

[0415] Figure 10 An embodiment in which a module accommodation portion is additionally provided in the back cover according to an embodiment of the present disclosure is shown. Therefore, hereinafter, descriptions of the same elements will be briefly given or omitted except for the module accommodation portion and elements related thereto.

[0416] Referring to Figure 10 and Figure 11 , the back cover 300 according to an embodiment of the present disclosure may further include at least one module accommodation portion 370 in which at least one sound generation module 500 is accommodated.

[0417] At least one module accommodation part 370 may be provided in the first rear cover 310 of the rear cover 300 and may be covered by the second rear cover 350. For example, at least one module accommodation part 370 may be provided to vertically penetrate 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. In order to make the display device thin in thickness and improve the simple back design of the display device, at least one module accommodation part 370 may be provided only in the first rear cover 310 and not in the second rear cover 350, so that it may not be exposed to the outside of the rear cover 300. At least one module accommodation part 370 may not completely penetrate the rear cover 300 and thus may be referred to as a module accommodation groove. At least one module accommodation part 370 may be referred to as a module insertion part, a module insertion groove, a module receiving part, a module receiving groove, or a groove, but the term is not limited thereto.

[0418] According to some embodiments of the present disclosure, the rear cover 300 may include two module accommodation parts 370, in which the first sound generation module 500-1 and the second sound generation module 500-2 are respectively accommodated or provided.

[0419] According to some embodiments of the present disclosure, each of the two module accommodation parts 370 may have a size capable of accommodating the corresponding sound generation module 500 therein. In addition, each of the two module accommodation parts 370 may have a height (or depth) smaller than the total height of the sound generation module 500. Each of the two module accommodation parts 370 may be provided to penetrate the first rear cover 310, and thus, the thickness (or depth) of the first rear cover 310 is smaller than the total height of the sound generation module 500. When the thickness of the first rear cover 310 is greater than the total height of the sound generation module 500, the height of the gap space GS provided between the display module 100 and the rear cover 300 may be insufficient, and thus, due to the physical contact between the first rear 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 noises such as frictional sounds may occur. Therefore, the thickness of the first rear cover 310 or the height (or depth) of the module accommodation part 370 may be set within a range that prevents physical contact between the first rear cover 310 and the display module 100 vibrating based on the driving of the vibration device 530.

[0420] According to some embodiments of the present disclosure, in addition to at least one sound generation 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 accommodation part 370 by using the first member 410 (or module fixing member), at least one sound generation module 500 is the same as Figures 2 to 5B the sound generation module shown, and thus its repeated description is omitted.

[0421] According to another embodiment of the present disclosure, the rear cover 300 may include a module receiving portion 370 in which the Figure 8 and Figure 9 shown one sound generating module 500 is received and disposed. Even for example, a module receiving portion 370 may be disposed to vertically penetrate 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.

[0422] Therefore, in a display device according to another embodiment of the present disclosure, since at least one sound generating module 500 is received and disposed in the module receiving portion 370 in the rear cover 300, the thickness may be reduced by the height (or depth) of the module receiving portion 370, and the weight may be reduced by the size of the module receiving portion 370. In a display device according to another embodiment of the present disclosure, since the sound generating module 500 is received and disposed in the module receiving portion 370 in the rear cover 300, the assembly process between the sound generating module 500 and the rear cover 300 may be simplified.

[0423] As another example, the rear cover 300 may include a plurality of holes 300h overlapping with at least one module receiving portion 370.

[0424] Each of the plurality of holes 300h may be disposed to vertically penetrate the second rear cover 350 of the rear cover 300 in the thickness direction Z, and may be connected to (or communicate with) at least one module receiving portion 370. The plurality of holes 300h may be radially disposed to overlap with the sound generating module 500 received in at least one module receiving portion 370. For a simple back design of the display device, the Figure 7 description of may be applied to the shape and size of each of the plurality of holes 300h in the same way, and thus, the repeated description is omitted.

[0425] Figure 12 FIG. shows a display device according to another embodiment of the present disclosure. Figure 13 is a cross-sectional view taken along the Figure 12 shown line II-II'.

[0426] Figure 12 and Figure 13 show an embodiment in which the structure of the sound generating module is modified in the display device shown in Figure 10 and Figure 11 Therefore, hereinafter, the repeated description of elements other than the sound generating module will be briefly given or omitted.

[0427] Referring to 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 rear cover 300 to vibrate the display module 100, and at least one sound generating module 500 may be received and disposed in at least one module receiving portion 370 provided in the rear cover 300.

[0428] At least one module receiving portion 370 in the rear cover 300 is the same as Figure 10 and Figure 11 the module receiving portion shown, and thus, its repeated description is omitted.

[0429] At least one sound generating module 500 may be received and disposed in at least one module receiving portion 370 provided in the rear cover 300 when modularized into one element. At least one sound generating module 500 according to some embodiments of the present disclosure may be received in at least one module receiving portion 370 provided in the first rear cover 310 of the rear cover 300, and may be supported by the front surface of the first rear cover 310. For example, at least one sound generating module 500 may have a box structure with one side open and including a border. 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).

[0430] According to an embodiment of the present disclosure, the rear central portion of the sound generating module 500 may pass through the module receiving portion 370, and may be disposed 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 (or stably placed thereon) by the front surface of the first rear cover 310, and may be disposed 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 or coupled to the rear surface of the heat dissipation member 150 provided on the last surface of the display module 100 by using the connecting member 550.

[0431] According to another embodiment of the present disclosure, the sound generating module 500 may be disposed or fixed to the second rear cover 350 by a plurality of screws. For example, the edge portion or boundary portion of the sound generating module 500 may be disposed or fastened to the first rear cover 310 by a plurality of screws. For example, each of the plurality of screws may pass through the edge portion of the sound generating module 500 and the connecting member 550, and may be disposed or fastened to the first rear cover 310.

[0432] According to another embodiment of the present disclosure, the sound generating module 500 may be disposed or fixed to the second rear cover 350 by bolts and nuts. The nut may be disposed 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.

[0433] Therefore, in a 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 accommodation portion 370 provided in the rear cover 300, the thickness may be reduced by the height (or depth) of the module accommodation portion 370, and the weight may be reduced by the size of the module accommodation portion 370. In a display device according to another embodiment of the present disclosure, since the sound generating module 500 is accommodated and disposed in the module accommodation portion 370 provided in the rear cover 300, the assembly process between the sound generating module 500 and the rear cover 300 may be simplified.

[0434] Figure 14 Shows Figure 12 and Figure 13 the sound generating module shown. Figure 15 Shows Figure 14 the module structure shown.

[0435] Referring to Figures 12 to 15 , the sound generating module 500 according to another embodiment of the present disclosure may include a module structure 2510, a vibration device 530, a connecting member 550, and a module bonding member 450.

[0436] The module structure 2510 may be accommodated and disposed in the module accommodation 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 metallic material.

[0437] The module structure 2510 according to some embodiments of the present disclosure may include a boundary portion or an edge portion 511, 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.

[0438] The edge portion 511 may have a quadrangular (e.g., quadrilateral) band shape and may be supported (or stably placed thereon) by the front surface of the rear cover 300 (e.g., the first rear cover 310) adjacent to the module accommodation portion 370. For example, the edge portion 511 may be an edge portion (or an edge part or a peripheral part or a boundary part) of a metal plate that is a base member for forming the module structure 2510.

[0439] The bottom portion 513 may be disposed on or fixed to the second rear cover 350 of the rear cover 300 exposed by the module accommodation portion 370. For example, the bottom portion 513 may pass through the module accommodation portion 370 and may be disposed on or fixed to the second rear cover 350 by using the first member 410 (or the module fixing member).

[0440] The inclined portion 515 may be disposed to be inclined between the edge portion 511 and the bottom portion 513, so that a receiving space may be defined on the bottom portion 513. For example, the bottom portion 513 and the inclined portion 515 may have such a structure by using a molding process: a portion of the metal plate other than the edge portion projects toward the rear cover 300. The bottom portion 513 and the inclined portion 515 may be referred to as a receiving portion, a forming portion, or a pocket portion for receiving the vibration device 530, but these terms are not limited thereto.

[0441] 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 edge portion 511 may be equal to or less than the height of the first rear cover 310. When the height H of the inclined portion 515 is greater than the height of the first rear cover 310, the edge portion 511 may not be stably supported by the front surface of the first rear cover 310, and a part of the inclined portion 515 and the edge portion 511 may project upward from the front surface of the first rear cover 310, resulting in a problem that a part of the inclined portion 515 and the edge 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 edge portion 511 may be equal to or less than the height of the first rear cover 310, so that the edge portion 511 is stably supported on (or stably placed on) the front surface of the first rear cover 310.

[0442] The vibration device 530 may be accommodated in the receiving space of the module structure 2510. The vibration device 530 according to some embodiments of the present disclosure may be disposed on or fixed to the bottom portion 513 of the module structure 2510 and may vibrate the display module 100 (e.g., the display panel 110). By using the module integration member 520, the vibration device 530 may be disposed on or fixed to the module structure 2510, or may be integrally provided with the module structure 2510. Therefore, the vibration device 530 and the module structure 2510 may be modularized into one element.

[0443] 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) configured 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 the same as the elements of the vibration device shown in Figures 2 to 5B the vibration device shown, and thus a repetitive description thereof is omitted.

[0444] The uppermost surface of the vibration device 530 according to some embodiments of the present disclosure may be on the same uppermost surface extension line HL (or horizontal line) as the edge portion 511 of the module structure 2510, or may protrude upward from the uppermost surface extension line 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, through only a simple module arrangement process, the uppermost surface of the vibration device 530 may 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.

[0445] The connection member 550 may be disposed between the edge portion 511 of the module structure 2510 and the rear surface of the display module 100. Thus, a gap space GS may be provided between the rear surface of the display module 100 and the rear cover 300, and the module structure 2510 may be disposed or coupled to the rear surface of the display module 100.

[0446] According to some embodiments of the present disclosure, one surface (or front surface) of the connection member 550 may be disposed 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 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 adhesive foam tape, but is not limited thereto. The connection member 550 may provide a vibration space around the vibration device 530 between the module structure 2510 and the display module 100.

[0447] The module bonding member 450 may be a double-sided bonding member between the display module 100 and the vibration device 530. The double-sided bonding 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 module bonding member 450 may be disposed on or coupled to the rear surface of the heat dissipation member 150 provided in the display module 100 (e.g., the rear surface of the display panel 110 or the display panel 110), and the other surface (or rear surface) of the module bonding member 450 may be disposed on or coupled to the bobbin 534 or the bobbin protection member 538 of the vibration device 530.

[0448] As another example, the heat dissipation member 150 coupled to or disposed on the rear surface of the display panel 110 may be integrally provided with the sound generation module 500. For example, the heat dissipation member 150 may be coupled to or disposed on each of the connection member 550 and the module bonding member 450 of the sound generation module 500 to cover the front surface of the sound generation module 500. Therefore, in the transfer process after the modular processing of the sound generation module 500 modularized into one element, the vibration device 530, the connection member 550, and the module bonding member 450 of the sound generation module 500 can be prevented from being exposed, and particles such as dust can be prevented from penetrating into the sound generation module 500.

[0449] The sound generation 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 a 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 each of the groove 510h, the hollow portion 530h, and the plurality of plate holes 531h of the sound generation module 500 shown, and thus, their repeated description is omitted. For example, Figure 6 each of the groove 510h, the hollow portion 530h, and the plurality of plate holes 531h of the sound generation module 500 shown may be applied to the corresponding elements of the sound generation module shown Figure 14 in the same or similar manner.

[0450] Figure 16A The rear surface of the module structure of the sound generation module according to an embodiment of the present disclosure is shown. Figure 16B The voice signal cable and the vibration device provided in the module structure of the sound generation module according to an embodiment of the present disclosure are shown.

[0451] Referring toFigure 16A and Figure 16B According to an embodiment of the present disclosure, the module structure 2510 may include a groove 510h and a plurality of cable holes 517 (or cable through-holes).

[0452] The groove 510h may be provided to penetrate 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 part of the rear surface of the vibration device 530. For example, the groove 510h may have a quadrilateral (e.g., a quadrangular) 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.

[0453] According to some embodiments of the present disclosure, the groove 510h may expose the line terminals 530p and 530m of the vibration device 530 at the rear surface of the module structure 2510.

[0454] Each of the plurality of cable holes 517 may extend from a corresponding corner of the groove 510h to have a specific size and shape, and may communicate with the corresponding corner of the groove 510h. For example, each of the plurality of cable holes 517 may 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 unloaded into the receiving space of the module structure 2510. Accordingly, the voice signal cable 590 may be electrically connected to the line terminals 530p and 530m of the vibration device 530 exposed at the groove 510h, and then may be unloaded into the receiving space of the module structure 2510 through the corresponding cable hole 517, and the voice signal cable 590 unloaded into the receiving space of the module structure 2510 may be unloaded 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.

[0455] According to an embodiment of the present disclosure, the module structure 2510 may accommodate the voice signal cable 590 connected to the line terminals 530p and 530m of the vibration device 530. Accordingly, in a transfer process after modular processing of the sound generation module 500 modularized as one element, defects such as disconnection of the voice signal cable 590 may be prevented.

[0456] Figure 17 The rear surface of a rear cover according to an embodiment of the present disclosure is shown.

[0457] Figure 17 It is a diagram for describing a setting structure of a voice signal cable through which a voice signal is applied to a sound generation module.

[0458] Referring to Figure 12 and Figure 17, according to an embodiment of the present disclosure, the voice signal cable 590 may be disposed between the display module 100 and the sound generation module 500, and may be discharged to the outside through the cable discharge hole 390 provided in the rear cover 300.

[0459] According to some embodiments of the present disclosure, one end or a portion of the voice signal cable 590 may be electrically connected to the line terminal provided in the corresponding sound generation 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 generation module 500 by welding.

[0460] According to some embodiments of the present disclosure, the other end or another portion of the voice signal cable 590 may be discharged to the outside of the receiving space of the corresponding sound generation module 500 via the receiving space of the corresponding sound generation module 500 and the space between the display module 100 and the sound generation module 500. Then, it may pass through the cable discharge hole 390 via the space between the display module 100 and the rear cover 300, and may be discharged to the outside of the display device. In Figure 17 , a portion of the voice signal cable 590 indicated by the dashed line may be covered by the rear cover 300, and thus may not be seen from the rear surface of the rear cover 300, and another portion of the voice signal cable 590 indicated by the thick solid line may be discharged to the outside of the display device via the cable discharge hole 390, and thus may be seen 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 that covers the circuit unit of the display device.

[0461] Therefore, since the voice signal cable 590 and the sound generation module 500 are covered by the rear cover 300, the display device according to the embodiment of the present disclosure may have a simple back design.

[0462] Figure 18 Shows a display device according to another embodiment of the present disclosure. Figure 19 Is a cross-sectional view taken along the Figure 18 Shown line III-III'. Figure 20 Is a cross-sectional view taken along the Figure 18 Shown line III-III'. Figure 21 Is a cross-sectional view taken along the Figure 18 Shown line III-III'.

[0463] Figure 18 And Figure 19 Shows based on Figures 12 to 17An embodiment in which the structure of the rear cover according to an embodiment of the present disclosure is modified by the shown display device. Therefore, hereinafter, descriptions of the same elements will be briefly given or omitted except for the rear cover and its related elements.

[0464] First, in Figures 12 to 17 In the shown display device, the rear cover 300 may include a plurality of module accommodating parts 370, and the sound generating module 500 modularized into one element is accommodated or inserted into the plurality of module accommodating parts 370. In a display device having only one sound generating module 500 based on the finished product structure of the display device, a rear cover 300 including only one module accommodating part 370 may be used. In addition, in a display device having no sound generating module 500 based on the finished product structure of the display device, a rear cover 300 having no module accommodating part 370 may be used. Manufacturing rear covers corresponding to each finished product structure of the display device may cost a large amount of money, and thus, the manufacturing cost of the display device may increase. To solve such a problem, a display device according to an embodiment of the present disclosure may include a rear cover that is universal regardless of the final product structure. For example, whether it is a display device not including the sound generating module 500 or a display device including the sound generating module 500, a display device according to an embodiment of the present disclosure may include a universal rear cover. Therefore, the cost (e.g., molding cost) spent on manufacturing the rear cover based on the finished product structure of the display device may be reduced, and by modularizing the sound generating module, the degree of freedom of whether the finished product is provided with the sound generating module or not can be improved.

[0465] Referring to Figure 18 and Figure 19 A display device according to another embodiment of the present disclosure may include a first sound generating module 500-1 to a third sound generating module 500-3 provided between the display module 100 and the rear cover 1300.

[0466] The display module 100 is the same as the display module shown in Figure 2 and Figures 3A - 3E and thus, repeated descriptions thereof are omitted.

[0467] The rear cover 1300 may be a universal rear cover and may include a plurality of module accommodating parts 370a to 370c. Each of the plurality of module accommodating parts 370 may be provided to penetrate the first rear cover 310 of the rear cover 1300 in the vertical direction Z. For example, the rear cover 1300 may include a first module accommodating part 370a overlapping with the first area (or left area) of the display module 100, a second module accommodating part 370b overlapping with the second area (or right area) of the display module 100, and a third module accommodating part 370c overlapping with the third area (or central area) of the display module 100 located between the first area and the second area.

[0468] The first sound generation module 500-1, the second sound generation module 500-2, and the third sound generation module 500-3 can be respectively received and disposed in the plurality of module receiving portions 370a, 370b, and 370c, and can respectively and individually vibrate the first region to the third region of the display module 100 (e.g., the display panel 110). Each of the first sound generation module 500-1, the second sound generation module 500-2, and the third sound generation module 500-3 is the same as Figures 3A - 3E , Figure 6 , Figure 10 and Figures 14 to 16B the sound generation modules shown, and thus, their repetitive descriptions are omitted.

[0469] Therefore, the display device according to another embodiment of the present disclosure can output a three-channel stereo based on the left sound LS, the right sound RS, and the center sound CS according to the vibration of the display module 100 (e.g., the display panel 110) based on the driving of each of the first sound generation module 500-1, the second sound generation module 500-2, and the third sound generation module 500-3.

[0470] As another example, the display device according to another embodiment of the present disclosure can include some of the first sound generation module 500-1, the second sound generation module 500-2, and the third sound generation module 500-3 based on a finished product structure. For example, the display device according to another embodiment of the present disclosure may not include the third sound generation module 500-3 among the first sound generation module 500-1, the second sound generation module 500-2, and the third sound generation module 500-3, and may include the first sound generation module 500-1 and the second sound generation module 500-2. For example, as Figure 18 and Figure 20 shown, each of the first sound generation module 500-1 and the second sound generation module 500-2 including the vibration device 530 can be respectively received and disposed in the first module receiving portion 370a and the second module receiving portion 370b provided in the rear cover 1300, and can respectively and individually vibrate the first region and the second region of the display module 100 (e.g., the display panel 110), thereby outputting a two-channel stereo based on the left sound LS and the right sound RS based on the vibration of each of the first region and the second region of the display panel 110.

[0471] In addition, in a display device according to another embodiment of the present disclosure, since the third sound generation module 500-3 is not accommodated or inserted into the third module accommodation part 370c provided in the rear cover 1300 and the third module accommodation part 370c is open, there may be a problem due to a change in sound pressure caused by the overlap between the gap space between the rear cover 1300 and the display module 100 and the third module accommodation part 370c, and the heat dissipation characteristics of the display module 100 overlapping with the third module accommodation part 370c may be reduced. To solve these problems, a display device according to another embodiment of the present disclosure may further include a cover body 900, as Figure 20 shown.

[0472] The cover body 900 may be a covering structure for covering the module accommodation part where the third sound generation module 500-3 is not inserted (or accommodated). The cover body 900 according to some embodiments of the present disclosure may be configured to have a structure substantially the same as the module structure 2510 of each of the sound generation modules 500-1, 500-2, and 500-3, and different from the sound generation modules 500-1, 500-2, and 500-3, the cover body 900 may not include a vibration device. For example, the cover body 900 may include Figure 15 the edge part 511, the bottom part 513, and the inclined part 515 of the module structure 2510 as shown. For example, the rear surface of the cover body 900 may be provided or fixed to the second rear cover 350 exposed by the third module accommodation part 370c by using a first member 910 (or a cover body fixing member). In addition, the front surface of the cover body 900 may be connected to the rear surface of the display module 100 by using a cover body bonding member 920. Therefore, the cover body 900 can cover the third module accommodation part 370c where the third sound generation module 500-3 is not accommodated, thereby solving the problems caused by the opening of the third module accommodation part 370c. The cover body 900 may be referred to as a hole cover, a cap, or a lid, but the term is not limited thereto.

[0473] As another example, a display device according to another embodiment of the present disclosure may not include all of the first sound generation module 500-1, the second sound generation module 500-2, and the third sound generation module 500-3 based on the finished product structure. For example, as Figure 18 and Figure 21As shown, in a display device according to another embodiment of the present disclosure, the first sound generation module 500-1, the second sound generation module 500-2, and the third sound generation module 500-3 may not be accommodated in the first module accommodation part 370a, the second module accommodation part 370b, and the third module accommodation part 370c provided in the rear cover 1300, and the first module accommodation part 370a, the second module accommodation part 370b, and the third module accommodation part 370c may be open, resulting in a reduction in heat dissipation characteristics in the display module 100 that overlaps with the first module accommodation part 370a, the second module accommodation part 370b, and the third module accommodation part 370c. To solve such a problem, the display device according to another embodiment of the present disclosure may further include a first cover body 900-1, a second cover body 900-2, and a third cover body 900-3, which are respectively accommodated and provided in the first module accommodation part 370a, the second module accommodation part 370b, and the third module accommodation part 370c.

[0474] Each of the first cover 900-1, the second cover 900-2, and the third cover 900-3 may 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. Different from 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 may 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 may be disposed on or fixed to the second rear 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 by 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 disposed on or coupled to the rear surface of the display module 100 by using the cover bonding 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 that do not accommodate or insert the first sound generating module 500-1, the second sound generating module 500-2, and the third sound generating module 500-3, thereby solving the problems arising from the opening of each of the first module accommodating portion 370a, the second module accommodating portion 370b, and the third module accommodating portion 370c. Therefore, the rear cover 1300 may include a plurality of module accommodating portions 370a, 370b, and 370c, and the plurality of module accommodating portions 370a, 370b, and 370c are selectively provided with the first sound generating module 500-1, the second sound generating module 500-2, and the third sound generating module 500-3 and the cover 900, so that the rear cover 1300 may be universal regardless of the finished structure of the display device.

[0475] Figure 22 A display device according to another embodiment of the present disclosure is shown.

[0476] Referring to Figure 22 , a display device according to another embodiment of the present disclosure may include at least one sound generating module 500 disposed on the rear surface of the rear cover 300. The at least one sound generating module 500 may be accommodated and disposed in at least one module accommodating portion 370 provided in the rear cover 300. The at least one sound generating module 500 may be attached to the rear cover 300.

[0477] At least one module accommodating portion 370 provided in the rear cover 300 and Figure 10 and Figure 11The module accommodation parts shown are the same, and thus, a repeated description thereof will be omitted.

[0478] At least one sound generating module 500 may be accommodated and disposed in at least one module accommodation part 370 provided in the rear cover 300 and modularized into one element. At least one sound generating module 500 according to some embodiments of the present disclosure may be accommodated in at least one module accommodation part 370 provided in the first rear cover 310 of the rear cover 300 and may be supported by the rear surface of the first rear 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 a 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).

[0479] Thus, in a 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 accommodation part 370 provided in the rear cover 300, the thickness may be reduced by the height (or depth) of the module accommodation part 370, and the weight may be reduced by the size of the module accommodation part 370. In a display device according to another embodiment of the present disclosure, since the sound generating module 500 is disposed on the rear surface of the rear cover 300, the assembly process between the sound generating module 500 and the rear cover 300 may be simplified.

[0480] Figures 23A to 23D A board according to another embodiment of the present disclosure is shown.

[0481] Referring to Figures 23A to 23D , a board may be used as a vibrating plate to generate sound.

[0482] For example, Figure 23A it may be a glass plate 601 including a glass material, and the glass plate 601 may be implemented as a sound plate, where Figures 3A - 3E , Figure 5A , Figure 5B , Figure 6 and Figures 14 to 16B the sound generating modules of are disposed on the rear surface of the glass plate 601 to output sound. Alternatively, the sound generating module or the sound generating device described below with reference to Figures 24A to 46B may be disposed on the rear surface of the glass plate 601. For example, the glass plate 601 may be set as a photo frame type. The sound generating module may be disposed on the rear surface of a photo frame including a photo or a picture, and thus, a user may hear sound while gazing at or viewing the photo or the picture.

[0483] As another example, Figure 23BIt can be a wooden board 602 including a wooden material, and the wooden board 602 can be implemented as a soundboard. For example, the wooden board 602 can be implemented as a soundboard, where Figures 3A - 3E 、 Figure 5A 、 Figure 5B 、 Figure 6 and Figures 14 to 16B The sound generation modules are provided on the rear surface of the wooden board 602 to output sound. Alternatively, the sound generation module or sound generation device described with reference to Figures 24A to 46B can be provided on the rear surface of the wooden board 602.

[0484] As another example, Figure 23C It can be a plastic board 603 including a plastic material, and the plastic board 603 can be implemented as a soundboard. For example, the plastic board 603 can be implemented as a soundboard, where Figures 3A - 3E 、 Figure 5A 、 Figure 5B 、 Figure 6 and Figures 14 to 16B The sound generation modules are provided on the rear surface of the plastic board 603 to output sound. Alternatively, the sound generation module or sound generation device described with reference to Figures 24A to 46B can be provided on the rear surface of the plastic board 603.

[0485] As another example, Figure 23D It can be a metal plate 604 including a metal material, and the metal plate 604 can be implemented as a soundboard. The metal plate 604 can be a metal injection material. For example, the metal plate 604 can be implemented as a soundboard, where Figures 3A - 3E 、 Figure 5A 、 Figure 5B 、 Figure 6 and Figures 14 to 16B The sound generation modules are provided on the rear surface of the metal plate 604 to output sound. Alternatively, the sound generation module or sound generation device described with reference to Figures 24A to 46B can be provided on the rear surface of the metal plate 604.

[0486] As another example, Figures 3A - 3E 、 Figure 5A 、 Figure 5B 、 Figure 6 and Figures 14 to 16B The sound generation modules can be provided in a projection screen or an image reproduction device to output sound, thereby providing stereo sound to the user. As another example, Figures 3A - 3E 、 Figure 5A 、 Figure 5B 、 Figure 6 and Figures 14 to 16B The sound generation modules can be provided in a device such as a Bluetooth device to output sound, thereby providing sound to the user.

[0487] As another example, when the sound generation module with multiple channels described below with reference to Figures 24A to 32E is provided in the implementation manner of Figures 23A to 23D and in a projection screen, an image reproduction device, or a Bluetooth device, stereo sound and realistic stereophonic sound or surround sound can be provided to the user.

[0488] As another example, when the sound generation module of a thin film type or a piezoelectric composite described below with reference to Figures 33 to 44C is provided in the implementation manner of Figures 23A to 23D 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 and realistic stereophonic sound or surround sound can be provided to the user.

[0489] Therefore, according to another implementation manner of the present disclosure, due to the application of a sound board and a modular sound generation module, images and stereo sound can be provided, thereby enhancing the user's immersive experience and providing realistic stereophonic sound or surround sound.

[0490] When the sound generation module described above with reference to Figures 1 to 23D is applied to a display device, the sound generation module can be provided in at least two of the three regions. For example, the sound generation module can be provided in the left region and the right region of the display device, and the left sound and the right sound can be output to the front region in front of the display panel. For example, the inventors have recognized that the sound of the display panel is output in the left-right direction, but the sound of the display panel is not output in the up-down direction. Multiple sound generation modules can be provided to enhance the sound of the display panel in the up-down direction, but when multiple sound generation modules are provided, there may be a problem that the thickness of the display device becomes thick. In addition, in order to output stereo sound, an additional speaker can be provided 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 provided based on the user position or the image position. Therefore, the inventors have conducted various experiments to implement such a sound generation module, in which the thickness of the display device is not thickened, and left sound, right sound, top sound (height sound), and bottom sound are realized based on the image. Through various experiments, the inventors have invented a display device including a sound generation module with a new structure, which realizes left sound, right sound, top sound, and bottom sound. This will be described below with reference to Figures 24A to 44C as follows.

[0491] Figure 24A and Figure 24BA display device including a sound generation module according to an embodiment of the present disclosure is shown.

[0492] Referring to Figure 24A and Figure 24B , a display device according to an embodiment of the present disclosure may include a board 30, and the board 30 includes a first region 1, a second region 2, a third region 3, a fourth region 4, and a fifth region 5. As an example, as described above with reference to Figures 1 to 22 , the board 30 may be a display panel 110 that displays an image. Hereinafter, examples in which the board 30 is the display panel 110 or the rear cover 300 will be described. As another example, as described above with reference to Figures 23A to 23D , the board 30 may be one of a glass plate 601, a wooden plate 602, a plastic plate 603, and a metal plate 604. As another example, a display device according to an embodiment of the present disclosure may further include a second board, and the second board includes a first region 1, a second region 2, a third region 3, a fourth region 4, and a fifth region 5. For example, the board 30 may be a display panel that displays an image, and a sound generating device or a sound generation module may be provided on the second board including the first region 1, the second region 2, the third region 3, the fourth region 4, and the fifth region 5. For example, the board 30 may display an image, and the second board may be a sound board that outputs sound.

[0493] The rear surface of the display panel 110 may include the first region 1 to the fifth region 5. For example, the first region 1 and the fourth region 4 may be the left regions of the rear surface of the display panel 110. For example, the second region 2 and the fifth region 5 may be the right regions of the rear surface of the display panel 110. For example, the third region 3 may be the central region of the rear surface of the display panel 110. As another example, when the sound generation module is provided on the rear surface of the rear cover 300 as described above with reference to Figure 2 , the first region 1 to the fifth region 5 may be the regions of the rear surface of the rear cover 300. Related descriptions may be applied to Figures 26A to 32E and Figures 41A to 44C in the same or similar manner. In the embodiments described below, an example in which the sound generation module is provided on the rear surface of the display panel will be described, but the embodiments are not limited thereto. In other embodiments, the sound generation module may be provided on the rear surface of the rear cover.

[0494] At least one sound generation module may be provided in at least one of the first region 1, the second region 2, the third region 3, the fourth region 4, and the fifth region 5. At least one sound generation module may include the vibration device or the sound generation module described above with reference to Figures 1 to 22 . The vibration device may be a vibration device including a voice coil.

[0495] For example, the fourth sound generation module 1500HL may be disposed in the fourth area 4 on the rear surface of the display panel 110. The sound generation module W1 integrated with the first woofer may be disposed in the first area 1 on the rear surface of the display panel 110. The fifth sound generation module 1500HR may be disposed in the fifth area 5 on the rear surface of the display panel 110, and the sound generation module W2 of the second integrated woofer may be disposed in the second area 2 on the rear surface of the display panel 110.

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

[0496] The sound generation module W1 of the first integrated woofer and the sound generation module W2 of the second integrated woofer may each be a sound generation module configured integrally with a woofer. Therefore, a separate woofer may not be provided. The sound generation module W1 of the first integrated woofer and the sound generation module W2 of the second integrated woofer may each be a sound generation module including a woofer. Hereinafter, reference will be made to Figure 25A and Figure 25B to describe the sound generation module W1 of the first integrated woofer and the sound generation module W2 of the second integrated woofer.

[0497] The sound generation module W1 of the first integrated woofer and the sound generation module W2 of the second integrated woofer may output sounds of about 60 Hz to about 40 kHz, and the third sound generation module 1500C, the fourth sound generation module 1500HL, and the fifth sound generation module 1500HR may output sounds of about 80 Hz to about 40 kHz. Therefore, the display device may output 3.2-channel sounds.

[0498] Compared with the sound generation modules on the left and right sides of the display panel, since the sound generation modules are further arranged on the upper and lower parts of the display panel, the left and right sounds as well as the top and bottom sounds can be enhanced, and the user can feel a sound field similar to real sound. For example, since the fourth sound generation module 1500HL and the fifth sound generation module 1500HR are further arranged, the sound can be output from the upper part of the display panel 110, thereby providing a display device for realizing a stereo including the left and right sounds as well as the top and bottom sounds. Therefore, 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 can be realized, and a true stereo of real sound including the stereo left and right sounds and the stereo top and bottom sounds can be realized, thereby providing real sound rather than virtual sound to the user. Therefore, a true stereo or surround sound of real sound including the stereo left and right sounds and the stereo top and bottom sounds can be provided to the user, thereby enhancing the sense of reality. Therefore, in a theater, a private cinema, and devices such as a television, the user can simultaneously feel real sounds and images similar to or the same as reality, and for example, can feel a true audio-visual (AV) or Dolby sound system.

[0499] In addition, when implementing Figures 23A to 23D in the sound board of Figure 24A and Figure 24B the sound generation module with multiple channels as shown, a true stereo or surround sound of real sound including the stereo left and right sounds and the stereo top and bottom sounds can be provided to the user, thereby enhancing the sense of reality. When arranging Figures 23A to 23D in the sound board of Figure 24A and Figure 24B the sound generation module with multiple channels as shown and a projection or image reproduction device, a true AV or Dolby sound system can be provided, enabling the user to simultaneously feel real sounds and images similar to or the same as reality. In addition, a stereo for providing the user with an immersive experience and a sense of reality can be provided. In addition, as described above with reference to Figures 1 to 22 a modular sound generation module can be applied. Therefore, in the case of arranging the sound generation module, the design freedom of the display device or the rear cover can be improved.

[0500] For example, the fourth sound generation module 1500HL and the fifth sound generation module 1500HR may be symmetrically arranged, but the present disclosure is not limited thereto. For example, the fourth sound generation module 1500HL and the fifth sound generation module 1500HR may be arranged on the same line, but the present disclosure is not limited thereto. For example, the sound generation module W1 of the first integrated bass speaker may be arranged symmetrically with the sound generation module W2 of the second integrated bass speaker, but the present disclosure is not limited thereto. For example, the sound generation module W1 of the first integrated bass speaker and the sound generation module W2 of the second integrated bass speaker may be arranged on the same line, but the present disclosure is not limited thereto. For example, the sound generation module W1 of the first integrated bass speaker and the sound generation module W2 of the second integrated bass speaker may be arranged symmetrically with the third sound generation module 1500C, but the present disclosure is not limited thereto. For example, the sound generation module W1 of the first integrated bass speaker and the sound generation module W2 of the second integrated bass speaker may be arranged on the same line as the third sound generation module 1500C, but the present disclosure is not limited thereto.

[0501] Referring to Figure 24B , the sound generation module W1 of the first integrated bass speaker and the sound generation module W2 of the second integrated bass speaker may be arranged asymmetrically with the third sound generation module 1500C, but the embodiments of the present disclosure are not limited thereto. For example, the sound generation module W1 of the first integrated bass speaker and the sound generation module W2 of the second integrated bass speaker may be arranged on different lines from the third sound generation module 1500C, but the embodiments of the present disclosure are not limited thereto. For example, the sound generation module W1 of the first integrated bass speaker may be separated from the fourth sound generation module 1500HL disposed in the fourth area 4. Therefore, the sound of the lower part of the display panel 110 can be more vividly realized in the sound generation module W1 of the first integrated bass speaker, and based on the distance between the sound generation module W1 of the first integrated bass speaker and the fourth sound generation module 1500HL, a sound for distinguishing the difference between the sound of the sound generation module W1 of the first integrated bass speaker and the sound of the fourth sound generation module 1500HL can be realized. In addition, the sound generation module W2 of the second integrated bass speaker may be separated from the fifth sound generation module 1500HR disposed in the fifth area 5. Therefore, the sound of the lower part of the display panel 110 can be more vividly realized in the sound generation module W2 of the second integrated bass speaker, and based on the distance between the sound generation module W2 of the second integrated bass speaker and the fifth sound generation module 1500HR, a sound for distinguishing the difference between the sound of the sound generation module W2 of the second integrated bass speaker and the sound of the fifth sound generation module 1500HR can be realized.

[0502] Referring to Figure 24A andFigure 24B , the sound generation module W1 of the first integrated bass speaker can be set to be asymmetric with the fourth sound generation module 1500HL. The sound generation module W2 of the second integrated bass speaker can be set to be asymmetric with the fifth sound generation module 1500HR. For example, the constructive or destructive interference of sound caused by the vibration interference between the vibration and standing wave generated by the sound generation module W1 of the first integrated bass speaker and the vibration and standing wave generated by the fourth sound generation module 1500HL can be reduced. In addition to the vibration based on the reproduced sound source, the unwanted constructive or destructive interference of sound caused by external interference will cause sound distortion, thus reducing the sound quality, and the asymmetric structure between the sound generation module W1 of the first integrated bass speaker and the fourth sound generation module 1500HL can prevent the unwanted interference, thus reproducing a natural sound similar to the original sound. The constructive or destructive interference of sound caused by the vibration interference between the vibration and standing wave generated by the sound generation module W2 of the second integrated bass speaker and the vibration and standing wave generated by the fifth sound generation module 1500HR can be reduced. In addition to the vibration based on the reproduced sound source, the unwanted constructive or destructive interference of sound caused by external interference will cause sound distortion, thus reducing the sound quality, and the asymmetric structure between the sound generation module W2 of the second integrated bass speaker and the fifth sound generation module 1500HR can prevent the unwanted interference, thus reproducing a natural sound similar to the original sound. As another example, the sound generation module W1 of the first integrated bass speaker can be set to be symmetric with the fourth sound generation module 1500HL. The sound generation module W2 of the second integrated bass speaker can be set to be symmetric with the fifth sound generation module 1500HR. For example, the sound reproduction positions can be aligned on the same line, and thus, compared with the asymmetric structure, effects such as reproducing sound at the same position can be achieved. Therefore, the sense of recognition of the sound position can be enhanced, thereby enhancing the sound localization.

[0503] As another example, at least one of the fourth sound generation module 1500HL and the fifth sound generation module 1500HR may be configured as a sound generation module including a woofer. For example, the sound generation module W1 integrating the first woofer may be disposed in the fourth region 4, and the sound generation module W2 integrating the second woofer may be disposed in the fifth region 5. For example, the sound generation module including a woofer may be disposed in one or more of the fourth region 4 and the fifth region 5. As another example, the sound generation module including a woofer may be disposed in the third region 3. As another example, the third sound generation module 1500C may be configured as a sound generation module including a woofer. Accordingly, the sound generation module including a woofer may be disposed in one or more of the first region 1 to the fifth region 5, and may output sound in the bass band, thereby providing a display device for outputting sound in the bass band, midrange band, and treble band. For example, the sound generation module may be driven based on the same signal or a mono signal applied thereto.

[0504] Figure 25A and Figure 25B FIG. shows a sound generation module according to another embodiment of the present disclosure.

[0505] The sound generation module 1800 according to another embodiment of the present disclosure may be a sound generation module integrating a woofer, a hybrid sound generation module, and a sound generation module having a woofer, but the term is not limited thereto. Figure 25A is a front view of the sound generation module, and Figure 25B is a cross-sectional view of the sound generation module.

[0506] Referring to Figure 25A and Figure 25B , the sound generation module 1800 may include a first sound generation device 1801 and a second sound generation device 1802. For example, the first sound generation device 1801 may be disposed on the rear surface of the display panel, and the second sound generation device 1802 may be spaced apart from the rear surface of the display panel.

[0507] The sound generation module 1800 may include a frame for accommodating the first sound generation device 1801 and the second sound generation device 1802. The frame may include a lower frame 1610a supporting the lower part of each of the first sound generation device 1801 and the second sound generation 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.

[0508] The lower frame 1610a may support the magnet 1620. The magnet 1620 may share 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 may be disposed 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 may be disposed near the magnet 1620. For example, the lower frame 1610a and the plate 1611 may be disposed under and over the magnet 1620, respectively, and the magnetic flux density generated by the magnet 1620, the coil 1660a and the second coil 1660b may be increased, thereby enhancing the vibration characteristics. The lower frame 1610a may be a yoke, but the term is not limited thereto.

[0509] The side frame 1610b may be connected to the lower frame 1610a and may include at least one hole 217 to output sound. For example, the hole 217 may be a vent hole. For example, the hole 217 may output the sound of the bass band generated by the vibration plate 214b of the second sound generating device 1802 in the air gap in the sound generating module 1800 to the rear area behind the display panel 110.

[0510] 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, and thus, the magnetic flux generated by the magnet 1620 may be allowed to be concentrated inside the second bobbin 1650b, thereby preventing the magnetic flux from leaking. The side frame 1610b may be a yoke, but the term is not limited thereto. 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.

[0511] 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 Figures 3A - 3E , Figure 6 and Figure 14 description is given, and therefore their detailed description is omitted.

[0512] The magnet 1620 can be disposed on the lower frame 1610a. For example, the magnet 1620 can be disposed between the plate 1611 and the lower frame 1610a. The lower frame 1610a and the plate 1611 can control the magnetic flux generated by the magnet 1620. For example, the magnet 1620 can be surrounded by the lower frame 1610a and the plate 1611. Thus, the magnetic flux generated by the magnet 1620 can be concentrated inside the bobbin 1650a and can be controlled.

[0513] 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 peripheral surface of the bobbin 1650a to generate a magnetic field in the first sound generating device 1801, the display panel can vibrate based on the magnetic field by using the bobbin ring 1652a. The bobbin ring 1652a can be disposed 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 sounds in the mid-high frequency band.

[0514] The second sound generating device 1802 can include a magnet 1620 disposed on the frame, a plate 1611 located on the magnet 1620, a second bobbin 1650b located near the magnet 1620, and a second coil 1660b and a second damper 1670b located near the second bobbin 1650b.

[0515] The diaphragm 214b can be disposed on the second bobbin 1650b. For example, the diaphragm 214b can be spaced apart from the rear surface of the display panel 110 and can prevent heat generated in the second bobbin 1650b from being transferred to the display panel.

[0516] When a sound generating current is applied to the second coil 1660b wound around the outer peripheral surface of the second bobbin 1650b to generate a magnetic field in the second sound generating device 1802, the second bobbin 1650b can vibrate the air layer or air gap at the peripheral portion of the diaphragm by using the diaphragm 214b based on the magnetic field. For example, the front surface of the second bobbin 1650b can contact the diaphragm 214b and can vibrate the diaphragm 214b based on the state of whether current is applied thereto. The second sound generating device 1802 can output sounds to the front region and the rear region with respect to the diaphragm 214b. For example, the second sound generating device 1802 can output sounds in the low frequency band. For example, the sounds generated by the diaphragm 214b of the second sound generating device 1802 can include a first low-pitched sound propagated to the upper portion of the diaphragm 214b and a second low-pitched sound propagated to the lower portion of the diaphragm 214b. For example, the second sound generating device 1802 can be a subwoofer, but the term is not limited thereto.

[0517] The magnet 1620 may be disposed on the lower frame 1610a. The plate 1611 may be spaced apart from the diaphragm 214b. The second bobbin 1650b may be disposed on the rear surface of the diaphragm 214b. For example, the second bobbin 1650b may surround the magnet 1620 and the plate 1611.

[0518] The second damper 1670b may be disposed between the first sound generating device 1801 and the second sound generating device 1802. For example, the second damper 1670b may be disposed between the damper 1670a of the first sound generating device 1801 and the second bobbin 1650b of the second sound generating device 1802. For example, the second damper 1670b may be disposed between the diaphragm 214b of the second sound generating device 1802 and the first sound generating device 1801. The diaphragm 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. The edge 1670c may be disposed on the diaphragm 214b. When the diaphragm 214b performs a vertical movement, the edge 1670c may prevent deformation (e.g., twisting of the diaphragm 214b), and thus may provide a clear sound quality and enhance 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.

[0519] The magnet 1620 of the first sound generating device 1801 and the second magnet 1620 of the second sound generating device 1802 may have opposite magnetic fields. The first sound generating device 1801 may directly vibrate the display panel to output sound in the high frequency band to the front area in front of the display panel, and the second sound generating device 1802 may output sound in the low frequency band to the rear area behind the display panel. Therefore, since the first sound generating device 1801 and the second sound generating device 1802 have opposite magnetic fields, each of the first sound generating device 1801 and the second sound generating device 1802 can be independently driven or controlled to vibrate.

[0520] Therefore, the sound generating module integrated with the subwoofer may include a subwoofer disposed near the sound generating module. The sound generating module may be disposed on the rear surface of the display panel and may generate sound in the mid-high frequency band, while the subwoofer may be spaced apart from the rear surface of the display panel and may perform vertical vibration to generate sound in the low frequency band. For example, the sound generating module and the subwoofer may be driven based on different sound signals or voice signals applied thereto. Therefore, the sound generating module integrated with the subwoofer may enhance the sound in the low frequency band.

[0521] Figure 26A and Figure 26BA display device including a sound generation module according to another embodiment of the present disclosure is shown.

[0522] Referring Figure 26A and Figure 26B , at least one sound generation module may be disposed in at least one of a first region 1, a second region 2, a third region 3, a fourth region 4, and a fifth region 5. For example, a first sound generation module 1500L may be disposed in the first region 1 on the rear surface of the display panel 110, and a fourth sound generation module 1500HL may be disposed in the fourth region 4 on the rear surface of the display panel 110. A second sound generation module 1500R may be disposed in the second region 2 on the rear surface of the display panel 110, and a fifth sound generation module 1500HR may be disposed in the fifth region 5 on the rear surface of the display panel 110. A third sound generation module 1500C may be disposed in the third region 3 on the rear surface of the display panel 110. As another example, as referred to above Figure 22 as described, the first to fifth sound generation modules may be disposed on the rear surface of the rear cover 300. For example, the first to fifth sound generation modules may be disposed in a module structure.

[0523] The first sound generation module 1500L may be the left channel of the display panel 110, and the fourth sound generation module 1500HL may be the top left channel of the display panel 110. The second sound generation module 1500R may be the right channel of the display panel 110, and the fifth sound generation module 1500HR may be the top right channel of the display panel 110. The third sound generation module 1500C may be the central channel of the display panel 110.

[0524] Referring Figure 26A and Figure 26B, the first sound generation module 1500L can be set to be symmetrical with the fourth sound generation module 1500HL, but is not limited thereto. For example, the first sound generation module 1500L can be arranged on the same line as the fourth sound generation module 1500HL, but is not limited thereto. For example, the sound reproduction positions can be aligned on the same line. Therefore, compared with an asymmetrical structure, effects such as sound reproduction at the same position can be achieved. Therefore, the sense of recognition of the sound position can be enhanced, thereby enhancing sound localization. For example, the second sound generation module 1500R can be set to be symmetrical with the fifth sound generation module 1500HR. For example, the second sound generation module 1500R can be arranged on the same line as the fifth sound generation module 1500HR, but is not limited thereto. For example, the sound reproduction positions can be aligned on the same line. Therefore, compared with an asymmetrical structure, effects such as sound reproduction at the same position can be achieved. Therefore, the sense of recognition of the sound position can be enhanced, thereby enhancing sound localization. For example, the first sound generation module 1500L and the fourth sound generation module 1500HL can be set to be symmetrical with the second sound generation module 1500R and the fifth sound generation module 1500HR, but the present disclosure is not limited thereto. For example, the first sound generation module 1500L and the fourth sound generation module 1500HL can be arranged on the same line as the second sound generation module 1500R and the fifth sound generation module 1500HR, but the embodiments of the present disclosure are not limited thereto.

[0525] Referring to Figure 26A , the first sound generation module 1500L and the second sound generation module 1500R can be arranged on the same line as the third sound generation module 1500C, but is not limited thereto. For example, the sound reproduction positions can be aligned on the same line. Therefore, compared with an asymmetrical structure, effects such as sound reproduction at the same position can be achieved. Therefore, the sense of recognition of the sound position can be enhanced, thereby enhancing sound localization.

[0526] Referring to Figure 26B, the first sound generation module 1500L and the second sound generation module 1500R can be set to be asymmetric with the third sound generation module 1500C, but the embodiments of the present disclosure are not limited thereto. For example, the first sound generation module 1500L and the second sound generation module 1500R can be arranged on different lines from the third sound generation module 1500C, but the embodiments of the present disclosure are not limited thereto. For example, the first sound generation module 1500L and the second sound generation module 1500R can be arranged on the same line. For example, the third sound generation module 1500C can be arranged on a different line from the first sound generation module 1500L. For example, the third sound generation module 1500C can be arranged on a different line from the second sound generation module 1500R. For example, the first sound generation module 1500L can be separated from the fourth sound generation module 1500HL arranged in the fourth area 4. Therefore, the sound of the lower part of the display panel 110 can be more vividly realized in the first sound generation module 1500L, and based on the distance between the first sound generation module 1500L and the fourth sound generation module 1500HL, a sound for distinguishing the difference between the sound of the first sound generation module 1500L and the sound of the fourth sound generation module 150HL can be realized. In addition, the second sound generation module 1500R can be separated from the fifth sound generation module 1500HR arranged in the fifth area 5. Therefore, the sound of the lower part of the display panel 110 can be more vividly realized in the second sound generation module 1500R, and based on the distance between the second sound generation module 1500R and the fifth sound generation module 1500HR, a sound for distinguishing the difference between the sound of the second sound generation module 1500R and the sound of the fifth sound generation module 1500HR can be realized.

[0527] The fourth sound generation module 1500HL can be arranged in the fourth area 4, the fifth sound generation module 1500HR can be arranged in the fifth area 5, and no sound generation module may be arranged in the sixth area 6 between the fourth area 4 and the fifth area 5. Therefore, the vibration of each of the fourth sound generation module 1500HL and the fifth sound generation module 1500HR can be attenuated or absorbed in the sixth area 6 of the display panel 110, so that the transmission of the sound in the fourth area 4 to the fifth area 5 can be blocked or reduced, and the transmission of the sound in the fifth area 5 to the fourth area 4 can be blocked or reduced. Therefore, the reduction of the sound quality caused by the sound interference occurring in the fourth sound generation module 1500HL and the fifth sound generation module 1500HR can be reduced, and the sound characteristics of the mid-high frequency band can be further enhanced.

[0528] Therefore, the first sound generation module 1500L and the fourth sound generation module 1500HL can be disposed in the first area 1 and the fourth area 4 which are the left areas of the rear surface of the display panel 110, and can vibrate the left area of the display panel 110. The second sound generation module 1500R and the fifth sound generation module 1500HR can be disposed in the second area 2 and the fifth area 5 which are the right areas of the rear surface of the display panel 110, and can vibrate the right area of the display panel 110. The third sound generation 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 generation module 1500L, the second sound generation module 1500R, the third sound generation module 1500C, the fourth sound generation module 1500HL, and the fifth sound generation module 1500HR can receive different vibration signals and can be independently driven respectively. For example, the first sound generation module 1500L and the fourth sound generation module 1500HL can generate sound by using the left area of the rear surface of the display panel 110 as a diaphragm, and the second sound generation module 1500R and the fifth sound generation module 1500HR can generate sound by using the right area of the rear surface of the display panel 110 as a diaphragm. In addition, the third sound generation module 1500C can generate sound by using the central area of the display panel 110 as a diaphragm.

[0529] In the display device according to an embodiment of the present disclosure, a woofer can be provided to further enhance the sound in the bass band. For example, one or more woofers can be further provided below at least one of the first sound generation module 1500L and the second sound generation module 1500R. For example, one or more woofers can also be provided below at least one of the first area 1 and the second area 2. For example, the first woofer W3 can be provided below the first area 1 of the display panel 110. For example, the first woofer W3 can be provided below the first sound generation module 1500L. For example, the second woofer W4 can be provided below the second area 2 of the display panel 110. For example, the second woofer W4 can be provided below the second sound generation module 1500R. Therefore, the first woofer W3 and the second woofer W4 can output the sound in the bass band. The first sound generation module 1500L, the second sound generation module 1500R, the third sound generation module 1500C, the fourth sound generation module 1500HL, and the fifth sound generation 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.

[0530] Compared with the sound generating modules disposed on the left and right sides of the display panel, since the sound generating modules are further disposed on the upper and lower portions of the display panel with respect to the width direction of the display panel, the left and right sounds and the top and bottom sounds can be enhanced, and the user can feel a sound field feeling like a real sound. For example, since the fourth sound generating module 1500HL and the fifth sound generating module 1500HR are further provided, sound can be output from the upper portion of the display panel 110, thereby providing a display device for implementing a stereo sound including the left and right sounds and the top and bottom sounds. Therefore, 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 can be realized, and a real stereo sound including the stereo left and right sounds and the stereo top and bottom sounds can be realized, thereby providing a real sound rather than a virtual sound to the user. Therefore, a real stereo sound or surround sound including the stereo left and right sounds and the stereo top and bottom sounds can be provided to the user, thereby enhancing the sense of reality. Therefore, in a theater, a private cinema, and a device such as a television, the user can simultaneously feel real sounds and images similar to or the same as reality, and for example, can feel a real AV (audio-visual) or Dolby sound system.

[0531] In addition, when Figures 23A to 23D is implemented in the sound board of Figure 24A and Figure 24B the sound generating module having multiple channels as shown, a real stereo sound or surround sound including the stereo left and right sounds and the stereo top and bottom sounds can be provided to the user, thereby enhancing the sense of reality. When Figure 24A and Figure 24B the sound generating module having multiple channels as shown and a projection or image reproduction device are disposed in Figures 23A to 23D the sound board of Figures 1 to 22 a real AV or Dolby sound system can be provided, enabling the user to simultaneously feel real sounds and images similar to or the same as reality.

For example, the tenth region 10 may be the region between the first region 1, the fourth region 4, and the seventh region 7 and the third region 3, the sixth region 6, and the ninth region 9. For example, the eleventh region 11 may be the region between the second region 2, the fifth region 5, and the eighth region 8 and the third region 3, the sixth region 6, and the ninth region 9. The reference numerals 1 to 11 representing the regions in the first region to the eleventh region may be arbitrarily displayed, and the classification of the reference numerals 1 to 11 and the first region to the eleventh region does not limit the description of the present disclosure. The related description may be applied in the same or similar manner to Figures 28 to 44C .

[0534] At least one sound generating module may be disposed in at least one of the first region 1 to the eleventh region 11. For example, the first sound generating module 1500L may be disposed in the first region 1 on the rear surface of the display panel 110, the fourth sound generating module 1500HL may be disposed in the fourth region 4 on the rear surface of the display panel 110, and the seventh sound generating module 1500BL may be disposed in the seventh region 7 on the rear surface of the display panel 110.

As another example, as referred to above with reference to Figure 22 As described above, the first to eleventh sound generating modules may be disposed on the rear surface of the rear cover.

[0536] For example, the first sound generation module 1500L may be set to be symmetrical with the fourth sound generation module 1500HL and / or the seventh sound generation module 1500BL, but is not limited thereto. For example, the first sound generation module 1500L may be arranged on the same line as the fourth sound generation module 1500HL and / or the seventh sound generation module 1500BL, but is not limited thereto. For example, the sound reproduction positions may be aligned on the same line. Therefore, compared with an asymmetrical structure, effects such as reproducing sound at the same position can be achieved. Accordingly, the sense of recognition of the sound position can be enhanced, thereby enhancing the sound localization.

[0537] For example, the second sound generation module 1500R may be set to be symmetrical with the fifth sound generation module 1500HR and / or the eighth sound generation module 1500BR, but is not limited thereto. For example, the second sound generation module 1500R may be arranged on the same line as the fifth sound generation module 1500HR and / or the eighth sound generation module 1500BR, but is not limited thereto. For example, the sound reproduction positions may be aligned on the same line. Therefore, compared with an asymmetrical structure, effects such as reproducing sound at the same position can be achieved. Accordingly, the sense of recognition of the sound position can be enhanced, thereby enhancing the sound localization.

[0538] For example, the third sound generation module 1500C may be set to be symmetrical with the sixth sound generation module 1500HC and / or the ninth sound generation module 1500BC, but is not limited thereto. For example, the third sound generation module 1500C may be arranged on the same line as the sixth sound generation module 1500HC and / or the ninth sound generation module 1500BC, but is not limited thereto. For example, the sound reproduction positions may be aligned on the same line. Therefore, compared with an asymmetrical structure, effects such as reproducing sound at the same position can be achieved. Accordingly, the sense of recognition of the sound position can be enhanced, thereby enhancing the sound localization.

[0539] For example, the tenth sound generation module 1500LC and the eleventh sound generation module 1500RC may be set to be symmetrical with at least one of the first sound generation module 1500L, the second sound generation module 1500R, and the third sound generation module 1500C, but is not limited thereto. For example, the tenth sound generation module 1500LC and the eleventh sound generation module 1500RC may be arranged on the same line as at least one of the first sound generation module 1500L, the second sound generation module 1500R, and the third sound generation module 1500C, but is not limited thereto. For example, the sound reproduction positions may be aligned on the same line. Therefore, compared with an asymmetrical structure, effects such as reproducing sound at the same position can be achieved. Accordingly, the sense of recognition of the sound position can be enhanced, thereby enhancing the sound localization.

[0540] For example, one of the fourth sound generation module 1500HL and the fifth sound generation module 1500HR can be set to be symmetrical with the sixth sound generation module 1500HC, but not limited thereto. For example, one of the fourth sound generation module 1500HL and the fifth sound generation module 1500HR can be arranged on the same line as the sixth sound generation module 1500HC, but not limited thereto. For example, the sound reproduction positions can be aligned on the same line, and thus, compared with the asymmetrical structure, effects such as reproducing sound at the same position can be achieved. Therefore, the sense of recognition of the sound position can be enhanced, thereby enhancing the sound localization. For example, one of the first sound generation module 1500L, the second sound generation module 1500R, the tenth sound generation module 1500LC, and the eleventh sound generation module 1500RC can be set to be symmetrical with the third sound generation module 1500C, but not limited thereto. For example, one of the first sound generation module 1500L, the second sound generation module 1500R, the tenth sound generation module 1500LC, and the eleventh sound generation module 1500RC can be arranged on the same line as the third sound generation module 1500C, but not limited thereto. For example, the sound reproduction positions can be aligned on the same line, and thus, compared with the asymmetrical structure, effects such as reproducing sound at the same position can be achieved. Therefore, the sense of recognition of the sound position can be enhanced, thereby enhancing the sound localization. For example, one of the seventh sound generation module 1500BL and the eighth sound generation module 1500BR can be set to be symmetrical with the ninth sound generation module 1500BC, but not limited thereto. For example, one of the seventh sound generation module 1500BL and the eighth sound generation module 1500BR can be arranged on the same line as the ninth sound generation module 1500BC, but not limited thereto. For example, the sound reproduction positions can be aligned on the same line, and thus, compared with the asymmetrical structure, effects such as reproducing sound at the same position can be achieved. Therefore, the sense of recognition of the sound position can be enhanced, thereby enhancing the sound localization.

[0541] Therefore, the first sound generation module 1500L, the fourth sound generation module 1500HL, and the seventh sound generation module 1500BL can be disposed in the first region 1, the fourth region 4, and the seventh region 7, which are the left regions of the rear surface of the display panel 110, and can vibrate the left region of the display panel 110. The second sound generation module 1500R, the fifth sound generation module 1500HR, and the eighth sound generation module 1500BR can be disposed in the second region 2, the fifth region 5, and the eighth region 8, which are the right regions of the rear surface of the display panel 110, and can vibrate the right region of the display panel 110. The third sound generation module 1500C, the sixth sound generation module 1500HC, and the ninth sound generation module 1500BC can be disposed in the third region 3, the sixth region 6, and the ninth region 9, which are the central regions of the rear surface of the display panel 110, and can vibrate the central region of the display panel 110. The first sound generation module 1500L, the second sound generation module 1500R, the third sound generation module 1500C, the fourth sound generation module 1500HL, the fifth sound generation module 1500HR, the sixth sound generation module 1500HC, the seventh sound generation module 1500BL, the eighth sound generation module 1500BR, the ninth sound generation module 1500BC, the tenth sound generation module 1500LC, and the eleventh sound generation module 1500RC can receive different vibration signals and can be independently driven. For example, the first sound generation module 1500L, the fourth sound generation module 1500HL, and the seventh sound generation module 1500BL can generate sound by using the left region of the rear surface of the display panel 110 as a diaphragm. The second sound generation module 1500R, the fifth sound generation module 1500HR, and the eighth sound generation module 1500BR can generate sound by using the right region of the rear surface of the display panel 110 as a diaphragm. The third sound generation module 1500C, the sixth sound generation module 1500HC, and the ninth sound generation module 1500BC can generate sound by using the central region of the rear surface of the display panel 110 as a diaphragm. The tenth sound generation module 1500LC and the eleventh sound generation module 1500RC can generate sound by using the left region, the central region, and the right region of the rear surface of the display panel 110 as a diaphragm. For example, the sixth sound generation module 1500HC can generate sound toward the upper part of the display panel 110. For example, the fourth sound generation module 1500HL, the fifth sound generation module 1500HR, and the sixth sound generation module 1500HC can generate sound toward the upper part of the display panel 110, thereby enhancing the sound of the upper part of the display panel 110.For example, the seventh sound generation module 1500BL, the eighth sound generation module 1500BR, and the ninth sound generation module 1500BC can generate sound toward the lower part of the display panel 110, thereby enhancing the sound of the lower part of the display panel 110.

[0542] In addition, a subwoofer can be provided to further enhance the sound in the bass range. For example, one or more subwoofers can also be provided below at least one of the seventh area 7 and the eighth area 8. For example, one or more subwoofers can also be provided below at least one of the seventh sound generation module 1500BL and the eighth sound generation module 1500BR. For example, the first subwoofer W3 can be provided below the seventh area 7 of the display panel 110. For example, the first subwoofer W3 can be provided below the seventh sound generation module 1500BL. For example, the second subwoofer W4 can be provided below the eighth area 8 of the display panel 110. For example, the second subwoofer W4 can be provided below the eighth sound generation module 1500BR. Therefore, the first subwoofer W3 and the second subwoofer W4 can output the sound in the bass range.

[0543] As another example, the first subwoofer W3 and the second subwoofer W4 may not be provided, and at least one of the seventh sound generation module 1500BL and the eighth sound generation module 1500BR may be configured as a sound generation module having a subwoofer. For example, the sound generation module W1 of the first integrated subwoofer can be provided in the seventh area 7, and the sound generation module W2 of the second integrated subwoofer can be provided in the eighth area 8. For example, the sound generation module having a subwoofer can be provided in one or more of the seventh area 7 and the eighth area 8. The description of the sound generation module W1 of the first integrated subwoofer and the sound generation module W2 of the second integrated subwoofer is the same as the description given above with reference to Figures 24A to 25B The description is the same, so their descriptions are omitted.

[0544] When the sound generation module W1 of the first integrated bass speaker is disposed in the seventh region 7, the sound generation module W1 of the first integrated bass speaker can be arranged to be symmetrical with one of the first sound generation module 1500L and the fourth sound generation module 1500HL. For example, the sound generation module W1 of the first integrated bass speaker can be disposed on the same line as one of the first sound generation module 1500L and the fourth sound generation module 1500HL. When the sound generation module W2 of the second integrated bass speaker is disposed in the eighth region 8, the sound generation module W2 of the second integrated bass speaker can be arranged to be symmetrical with one of the second sound generation module 1500R and the fifth sound generation module 1500HR. For example, the sound generation module W2 of the second integrated bass speaker can be disposed on the same line as one of the second sound generation module 1500R and the fifth sound generation module 1500HR. For example, the sound reproduction positions can be aligned on the same line, and thus, compared with the asymmetrical structure, effects such as reproducing sound at the same position can be achieved. Therefore, the sense of recognition of the sound position can be enhanced, thereby enhancing the sound localization.

[0545] As another example, when the sound generation module W1 of the first integrated woofer is disposed in the seventh region 7, the sound generation module W1 of the first integrated woofer can be set to be asymmetric with one of the first sound generation module 1500L and the fourth sound generation module 1500HL. For example, the sound generation module W1 of the first integrated woofer can be disposed on a different line from one of the first sound generation module 1500L and the fourth sound generation module 1500HL. When the sound generation module W2 of the second integrated woofer is disposed in the eighth region 8, the sound generation module W2 of the second integrated woofer can be set to be asymmetric with one of the second sound generation module 1500R and the fifth sound generation module 1500HR. For example, the sound generation module W2 of the second integrated woofer can be disposed on a different line from one of the second sound generation module 1500R and the fifth sound generation module 1500HR. For example, the sound generation module W1 of the first integrated woofer and the sound generation module W2 of the second integrated woofer can be disposed on different lines from the third sound generation module 1500C. For example, constructive or destructive interference of sound caused by vibration interference between the vibration and standing wave generated by the sound generation module W1 of the first integrated woofer and the vibration and standing wave generated by the fourth sound generation module 1500HL or the seventh sound generation module 1500BL can be reduced. In addition to the vibration based on the reproduced sound source, the unwanted constructive or destructive interference of sound caused by external interference can cause sound distortion, thereby degrading the sound quality, and the asymmetric structure between the sound generation module W1 of the first integrated woofer and one of the fourth sound generation module 1500HL and the seventh sound generation module 1500BL can prevent the unwanted interference, thereby reproducing a natural sound similar to the original sound. Constructive or destructive interference of sound caused by vibration interference between the vibration and standing wave generated by the sound generation module W2 of the second integrated woofer and the vibration and standing wave generated by the fifth sound generation module 1500HR or the eighth sound generation module 1500BR can be reduced. In addition to the vibration based on the reproduced sound source, the unwanted constructive or destructive interference of sound caused by external interference can cause sound distortion, thereby degrading the sound quality, and the asymmetric structure between the sound generation module W2 of the second integrated woofer and one of the fifth sound generation module 1500HR and the eighth sound generation module 1500BR can prevent the unwanted interference, thereby reproducing a natural sound similar to the original sound.

[0546] As another example, the first bass speaker W3 and the second bass speaker W4 may not be provided, and at least one of the first sound generation module 1500L and the second sound generation module 1500R may be configured to be a sound generation module including a bass speaker or a sound generation module having a bass speaker. For example, the sound generation module W1 of the first integrated bass speaker may be provided in the first area 1, and the sound generation module W2 of the second integrated bass speaker may be provided in the second area 2. For example, the sound generation module including a bass speaker may be provided in one or more of the first area 1 and the second area 2. The descriptions of the sound generation module W1 of the first integrated bass speaker and the sound generation module W2 of the second integrated bass speaker are the same as those given above with reference to Figures 24A to 25B The description is the same, so their descriptions are omitted. The description related thereto is the same as the description of the example in which the sound generation module W1 of the first integrated bass speaker and the sound generation module W2 of the second integrated bass speaker are provided in the seventh area 7 and the eighth area 8, so it is omitted.

[0547] As another example, the first bass speaker W3 and the second bass speaker W4 may not be provided, and at least one of the tenth sound generation module 1500LC and the eleventh sound generation module 1500RC may be configured to be a sound generation module including a bass speaker. For example, the sound generation module W1 of the first integrated bass speaker may be provided in the tenth area 10, and the sound generation module W2 of the second integrated bass speaker may be provided in the eleventh area 11. For example, the sound generation module including a bass speaker may be provided in one or more of the tenth area 10 and the eleventh area 11.

[0548] As another example, the first bass speaker W3 and the second bass speaker W4 may not be provided, and at least one of the fourth sound generation module 1500HL and the fifth sound generation module 1500HR may be configured to be a sound generation module including a bass speaker. For example, the sound generation module W1 of the first integrated bass speaker may be provided in the fourth area 4, and the sound generation module W2 of the second integrated bass speaker may be provided in the fifth area 5. For example, the sound generation module including a bass speaker may be provided in one or more of the fourth area 4 and the fifth area 5.

[0549] As another example, the first bass speaker W3 and the second bass speaker W4 may not be provided, and at least one of the sixth sound generation module 1500HC and the ninth sound generation module 1500BC may be configured as a sound generation module including a bass speaker. For example, the sound generation module W1 of the first integrated bass speaker may be provided in the sixth region 6, and the sound generation module W2 of the second integrated bass speaker may be provided in the ninth region 9. For example, the sound generation module including a bass speaker may be provided in one or more of the sixth region 6 and the ninth region 9. As another example, the sound generation module including a bass speaker may be provided in the third region 3. For example, the third sound generation module 1500C may be configured as a sound generation module including a bass speaker.

[0550] Therefore, the bass speaker may not be provided separately, and the sound generation module of the integrated bass speaker may be provided in one or more of the first region 1 to the eleventh region 11, and the sound of the bass band may be output, thereby providing a display device for outputting the sounds of the bass band, the midrange band, and the treble band. For example, the sound generation module may be driven based on the same signal or a mono signal applied thereto.

[0551] The first sound generation module 1500L, the second sound generation module 1500R, the third sound generation module 1500C, the fourth sound generation module 1500HL, the fifth sound generation module 1500HR, the sixth sound generation module 1500HC, the seventh sound generation module 1500BL, the eighth sound generation module 1500BR, the ninth sound generation module 1500BC, the tenth sound generation module 1500LC, and the eleventh sound generation module 1500RC may output sounds of approximately 80 Hz to approximately 40 kHz. The first bass speaker W3 and the second bass speaker W4 may output sounds of 80 Hz or lower. Therefore, the display device may output 11.1-channel sound.

[0552] The display device according to an embodiment of the present disclosure may implement left and right sounds corresponding to a left image and a right image and top and bottom sounds corresponding to an upper image and a lower image, and may implement a true stereo of true sounds including stereo left and right sounds and stereo top and bottom sounds, thereby providing true sounds rather than virtual sounds to the user. Therefore, a true stereo or surround sound including stereo left and right sounds and stereo top and bottom sounds of true sounds may be provided to the user, thereby enhancing the sense of reality. Therefore, in a theater, a private cinema, and a device such as a television, the user may simultaneously feel true sounds and images similar to or the same as reality, and for example, may feel a true AV or Dolby sound system.

[0553] In addition, when implementing Figures 23A to 23D in the soundboard of Figure 24A and Figure 24B the sound generation module with multiple channels shown, a real sound or a real stereo sound or a surround sound including a stereo left sound and a right sound as well as a stereo top sound and a bottom sound can be provided to the user, thereby enhancing the sense of reality.

In addition, a stereo sound for providing the user with an immersive experience and a sense of reality can be provided. In addition, as described above with reference to Figures 1 to 22 a modular sound generation module can be applied. Therefore, in the case of setting the sound generation module, the design freedom of the display device or the rear cover can be improved.

For example, the second sound generating module 1500R can be set to be symmetric with the fifth sound generating module 1500HR and / or the eighth sound generating module 1500BR, but not limited thereto. 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 not limited thereto. For example, the third sound generating module 1500C can be set to be symmetric with the sixth sound generating module 1500HC and / or the ninth sound generating module 1500BC, but not limited thereto. 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 not limited thereto. For example, the sound reproduction positions can be aligned on the same line. Therefore, compared with an asymmetric structure, effects such as reproducing sound at the same position can be achieved. Therefore, the sense of recognition of the sound position can be enhanced, thereby enhancing the sound localization.

[0559] For example, the tenth sound generation module 1500LC can be set to be symmetrical with the twelfth sound generation module 1500HLC and / or the fourteenth sound generation module 1500BLC, but not limited thereto. For example, the tenth sound generation module 1500LC can be arranged on the same line as the twelfth sound generation module 1500HLC and / or the fourteenth sound generation module 1500BLC, but not limited thereto. For example, the eleventh sound generation module 1500RC can be set to be symmetrical with the thirteenth sound generation module 1500HRC and / or the fifteenth sound generation module 1500BRC, but not limited thereto. For example, the eleventh sound generation module 1500RC can be arranged on the same line as the thirteenth sound generation module 1500HRC and / or the fifteenth sound generation module 1500BRC, but not limited thereto. For example, the sound reproduction positions can be aligned on the same line. Therefore, compared with an asymmetrical structure, effects such as reproducing sound at the same position can be achieved. Therefore, the sense of recognition of the sound position can be enhanced, thereby enhancing the sound localization.

[0560] For example, one of the fourth sound generation module 1500HL, the fifth sound generation module 1500HR, and the sixth sound generation module 1500HC can be set to be symmetrical with one of the twelfth sound generation module 1500HLC and the thirteenth sound generation module 1500HRC, but not limited thereto. For example, one of the fourth sound generation module 1500HL, the fifth sound generation module 1500HR, and the sixth sound generation module 1500HC can be arranged on the same line as one of the twelfth sound generation module 1500HLC and the thirteenth sound generation module 1500HRC, but not limited thereto. For example, one of the first sound generation module 1500L, the second sound generation module 1500R, and the third sound generation module 1500C can be set to be symmetrical with one of the tenth sound generation module 1500LC and the eleventh sound generation module 1500RC, but not limited thereto. For example, one of the first sound generation module 1500L, the second sound generation module 1500R, and the third sound generation module 1500C can be arranged on the same line as one of the tenth sound generation module 1500LC and the eleventh sound generation module 1500RC, but not limited thereto. For example, one of the seventh sound generation module 1500BL, the eighth sound generation module 1500BR, and the ninth sound generation module 1500BC can be set to be symmetrical with one of the fourteenth sound generation module 1500BLC and the fifteenth sound generation module 1500BRC, but not limited thereto. For example, one of the seventh sound generation module 1500BL, the eighth sound generation module 1500BR, and the ninth sound generation module 1500BC can be arranged on the same line as one of the fourteenth sound generation module 1500BLC and the fifteenth sound generation module 1500BRC, but not limited thereto. For example, the sound reproduction positions can be aligned on the same line. Therefore, compared with an asymmetrical structure, effects such as reproducing sound at the same position can be achieved. Therefore, the sense of recognition of the sound position can be enhanced, thereby enhancing the sound localization.

[0561] In addition, a subwoofer can be provided to further enhance the sound in the bass range. For example, the subwoofer can be further provided below at least one of the first region 1 to the fifteenth region 15. For example, the subwoofer can be further provided below at least one of the first sound generation module 1500L to the fifteenth sound generation module 1500BRC. For example, the first subwoofer W3 can be provided below the seventh region 7 of the display panel 110. For example, the first subwoofer W3 can be provided below the seventh sound generation module 1500BL. For example, the first subwoofer W3 can be provided between the seventh region 7 and the fourteenth region 14. For example, the second subwoofer W4 can be provided below the eighth region 8 of the display panel 110. For example, the second subwoofer W4 can be provided below the eighth sound generation module 1500BR. For example, the second subwoofer W4 can be provided between the eighth region 8 and the fifteenth region 15. Therefore, the first subwoofer W3 and the second subwoofer W4 can output the sound in the bass range.

[0562] As another example, the first subwoofer W3 and the second subwoofer W4 may not be provided, and at least one of the seventh sound generation module 1500BL and the eighth sound generation module 1500BR may be configured as a sound generation module including a subwoofer. For example, the sound generation module W1 of the first integrated subwoofer can be provided in the seventh region 7, and the sound generation module W2 of the second integrated subwoofer can be provided in the eighth region 8. For example, the sound generation module including a subwoofer can be provided in one or more of the seventh region 7 and the eighth region 8. The description of the sound generation module W1 of the first integrated subwoofer and the sound generation module W2 of the second integrated subwoofer is the same as the description given above with reference to Figures 24A to 25B The description is the same, and thus the description thereof is omitted.

[0563] When the sound generation module W1 of the first integrated bass speaker is disposed in the seventh region 7, the sound generation module W1 of the first integrated bass speaker can be arranged to be symmetrical with one of the first sound generation module 1500L and the fourth sound generation module 1500HL. For example, the sound generation module W1 of the first integrated bass speaker can be arranged on the same line as one of the first sound generation module 1500L and the fourth sound generation module 1500HL. When the sound generation module W2 of the second integrated bass speaker is disposed in the eighth region 8, the sound generation module W2 of the second integrated bass speaker can be arranged to be symmetrical with one of the second sound generation module 1500R and the fifth sound generation module 1500HR. For example, the sound generation module W2 of the second integrated bass speaker can be arranged on the same line as one of the second sound generation module 1500R and the fifth sound generation module 1500HR. For example, the sound reproduction positions can be aligned on the same line, and thus, compared with an asymmetrical structure, effects such as reproducing sound at the same position can be achieved. Therefore, the sense of recognition of the sound position can be enhanced, thereby enhancing the sound localization.

[0564] As another example, when the sound generation module W1 of the first integrated woofer is disposed in the seventh region 7, the sound generation module W1 of the first integrated woofer can be set to be asymmetric with one of the first sound generation module 1500L and the fourth sound generation module 1500HL. For example, the sound generation module W1 of the first integrated woofer can be disposed on a different line from one of the first sound generation module 1500L and the fourth sound generation module 1500HL. When the sound generation module W2 of the second integrated woofer is disposed in the eighth region 8, the sound generation module W2 of the second integrated woofer can be set to be asymmetric with one of the second sound generation module 1500R and the fifth sound generation module 1500HR. For example, the sound generation module W2 of the second integrated woofer can be disposed on a different line from one of the second sound generation module 1500R and the fifth sound generation module 1500HR. For example, the sound generation module W1 of the first integrated woofer and the sound generation module W2 of the second integrated woofer can be disposed on different lines from the third sound generation module 1500C. For example, it is possible to reduce the constructive or destructive interference of sound caused by the vibration interference between the vibration and standing wave generated by the sound generation module W1 of the first integrated woofer and the vibration and standing wave generated by the fourth sound generation module 1500HL or the seventh sound generation module 1500BL. In addition to the vibration based on the reproduced sound source, the unwanted constructive or destructive interference of sound caused by external interference causes sound distortion, thereby degrading the sound quality, and the asymmetric structure between the sound generation module W1 of the first integrated woofer and one of the fourth sound generation module 1500HL and the seventh sound generation module 1500BL can prevent the unwanted interference, thereby reproducing a natural sound similar to the original sound. It is possible to reduce the constructive or destructive interference of sound caused by the vibration interference between the vibration and standing wave generated by the sound generation module W2 of the second integrated woofer and the vibration and standing wave generated by the fifth sound generation module 1500HR or the eighth sound generation module 1500BR. In addition to the vibration based on the reproduced sound source, the unwanted constructive or destructive interference of sound caused by external interference causes sound distortion, thereby degrading the sound quality, and the asymmetric structure between the sound generation module W2 of the second integrated woofer and one of the fifth sound generation module 1500HR and the eighth sound generation module 1500BR can prevent the unwanted interference, thereby reproducing a natural sound similar to the original sound.

For example, the sound generation module including a bass speaker may be provided in one or more of the first region 1 and the second region 2. The descriptions of the sound generation module W1 of the first integrated bass speaker and the sound generation module W2 of the second integrated bass speaker are the same as those given above with reference to Figures 24A to 25B The description is the same as that given above, and thus their descriptions are omitted. The description related thereto is the same as the description of the example in which the sound generation module W1 of the first integrated bass speaker and the sound generation module W2 of the second integrated bass speaker are provided in the first region 1 and the second region 2, and thus is omitted.

For example, the sound generation module W1 of the first integrated bass speaker may be provided in the tenth region 10, and the sound generation module W2 of the second integrated bass speaker may be provided in the eleventh region 11. For example, the sound generation module including a bass speaker may be provided in one or more of the tenth region 10 and the eleventh region 11. The descriptions of the sound generation module W1 of the first integrated bass speaker and the sound generation module W2 of the second integrated bass speaker are the same as those given above with reference to Figures 24A to 25B The description is the same as that given above, and thus their descriptions are omitted. The description related thereto is the same as the description of the example in which the sound generation module W1 of the first integrated bass speaker and the sound generation module W2 of the second integrated bass speaker are provided in the tenth region 10 and the eleventh region 11, and thus is omitted.

[0567] As another example, the first bass speaker W3 and the second bass speaker W4 may not be provided, and at least one of the fourteenth sound generation module 1500BLC and the fifteenth sound generation module 1500BRC may be configured as a sound generation module including a bass speaker. For example, the sound generation module W1 of the first integrated bass speaker may be provided in the fourteenth region 14, and the sound generation module W2 of the second integrated bass speaker may be provided in the fifteenth region 15. For example, the sound generation module including a bass speaker may be provided in one or more of the fourteenth region 14 and the fifteenth region 15. The descriptions of the sound generation module W1 of the first integrated bass speaker and the sound generation module W2 of the second integrated bass speaker are the same as those given above with reference to Figures 24A to 25B The description is the same, so their descriptions are omitted. The description related thereto is the same as the description of the example in which the sound generation module W1 of the first integrated bass speaker and the sound generation module W2 of the second integrated bass speaker are provided in the fourteenth region 14 and the fifteenth region 15, so it is omitted.

[0568] As another example, the first bass speaker W3 and the second bass speaker W4 may not be provided, and at least one of the fourth sound generation module 1500HL and the fifth sound generation module 1500HR may be configured as a sound generation module including a bass speaker. For example, the sound generation module W1 of the first integrated bass speaker may be provided in the fourth region 4, and the sound generation module W2 of the second integrated bass speaker may be provided in the fifth region 5. For example, the sound generation module including a bass speaker may be provided in one or more of the fourth region 4 and the fifth region 5.

[0569] As another example, the first bass speaker W3 and the second bass speaker W4 may not be provided, and at least one of the twelfth sound generation module 1500HLC and the thirteenth sound generation module 1500HRC may be configured as a sound generation module including a bass speaker. For example, the sound generation module W1 of the first integrated bass speaker may be provided in the twelfth region 12, and the sound generation module W2 of the second integrated bass speaker may be provided in the thirteenth region 13. For example, the sound generation module including a bass speaker may be provided in one or more of the twelfth region 12 and the thirteenth region 13.

[0570] As another example, the first bass speaker W3 and the second bass speaker W4 may not be provided, and at least one of the sixth sound generation module 1500HC and the ninth sound generation module 1500BC may be configured as a sound generation module including a bass speaker.

For example, the sound generation module including a bass speaker may be provided in one or more of the sixth region 6 and the ninth region 9. As another example, the sound generation module including a bass speaker may be provided in the third region 3. For example, the third sound generation module 1500C may be configured as a sound generation module including a bass speaker.

[0571] Therefore, the bass speaker may not be provided separately, and the sound generation module of the integrated bass speaker may be provided in one or more of the first region 1 to the fifteenth region 15, and may output the sound of the bass band, thereby providing a display device for outputting the sounds of the bass band, the midrange band, and the treble band. For example, the sound generation module may be driven based on the same signal or a mono signal applied thereto.

[0572] The first sound generation module 1500L, the second sound generation module 1500R, the third sound generation module 1500C, the fourth sound generation module 1500HL, the fifth sound generation module 1500HR, the sixth sound generation module 1500HC, the seventh sound generation module 1500BL, the eighth sound generation module 1500BR, the ninth sound generation module 1500BC, the tenth sound generation module 1500LC, the eleventh sound generation module 1500RC, the twelfth sound generation module 1500HLC, the thirteenth sound generation module 1500HRC, the fourteenth sound generation module 1500BLC, and the fifteenth sound generation module 1500BRC may output sounds of approximately 80 Hz to approximately 40 kHz. The first bass speaker W3 and the second bass speaker W4 may output sounds of 80 Hz or lower. Therefore, the display device may output 15.1-channel sound.

[0573] A display device according to an embodiment of the present disclosure can implement left and right sounds corresponding to a left image and a right image, and top and bottom sounds corresponding to an upper image and a lower image, and can implement a true stereo of true sounds including stereo left and right sounds and stereo top and bottom sounds, thereby providing true sounds rather than virtual sounds to a user. Therefore, a true stereo or surround sound of true sounds including stereo left and right sounds and stereo top and bottom sounds can be provided to the user, thereby enhancing the sense of reality. Therefore, in a theater, a private cinema, and devices such as a television, a user can simultaneously feel true sounds and images similar to or the same as reality, and for example, can feel a true AV or Dolby sound system.

[0574] In addition, when a sound generation module having multiple channels as shown in Figures 23A to 23D is implemented in the sound board of Figure 24A and Figure 24B , a true stereo or surround sound of true sounds including stereo left and right sounds and stereo top and bottom sounds can be provided to the user, thereby enhancing the sense of reality. When a sound generation module having multiple channels and a projection or image reproduction device as shown in Figures 23A to 23D are provided in the sound board of Figure 24A and Figure 24B , a true AV or Dolby sound system can be provided, enabling a user to simultaneously feel true sounds and images similar to or the same as reality. In addition, a stereo for providing a user with an immersive experience and a sense of reality can be provided. Further, as described above with reference to Figures 1 to 22 , a modular sound generation module can be applied. Therefore, in the case of setting the sound generation module, the design freedom of the display device or the rear cover can be improved.

[0575] Figures 29A to 29E A sound generation module and a partition according to another embodiment of the present disclosure are shown.

[0576] Referring to Figures 29A to 29E, the display panel 110 may include a first region 1 to a sixth region 6. The first region 1 to the sixth region 6 may have the same area, but is not limited thereto. For example, the first region 1 to the sixth region 6 may be arranged at equal intervals or distances. For example, all channels of the sound generation module provided in the first region 1 to the sixth region 6 may reproduce or output sounds having the same frequency domain or range, so that the harmony between the channels may be uniform. Therefore, the difference in sound quality between the case with an acoustic effect (for example, the case where the sound field is widened) and the case without an acoustic effect (for example, the case where the sound field is not widened) may be reduced, and a uniform or constant sound quality may be achieved. As another example, the areas of the first region 1, the second region 2, and the third region 3 may be larger than the areas of the fourth region 4, the fifth region 5, and the sixth region 6. For example, the low sound range of the left and right stereo may be enhanced, so that the quality of the normal sound without an acoustic effect may be enhanced. As another example, the areas of the fourth region 4, the fifth region 5, and the sixth region 6 may be smaller than the areas of the first region 1, the second region 2, and the third region 3. For example, the low sound range of the channels associated with the acoustic effect may be enhanced. Therefore, in the case of reproducing sounds with an acoustic effect, the sound field as the space for expressing the sound may be increased, thereby enhancing the acoustic effect of expressing the sound position. Therefore, the size of each of the first region 1 to the sixth region 6 may be adjusted based on the desired sound band.

[0577] Referring to Figures 29A to 29E , a partition may also be provided near the sound generation 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 sounds or may separate channels, and may prevent or reduce the occurrence of unclear sounds 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 of providing the partition on the rear cover will be described, but the embodiments of the present disclosure are not limited thereto. In other embodiments, the partition may be provided on the rear surface of the display panel 110. To illustrate the sound generation module and the partition, an example of providing the partition on the rear cover will be described. For example, in the case where the partition is provided on the rear cover, the influence of the partition on the image quality of the display panel may be reduced. As referred to above Figure 22 described, in the case where the sound generation module is provided on the rear cover, the partition may be provided on the rear cover.

[0578] Referring to Figure 29A, the partition part can separate the left sound and the right sound output from the sound generation module provided on the rear surface of the display panel 110. For example, the partition part can be provided between the rear cover 300 and the display panel 110 corresponding to the first area 1 to the sixth area 6 of the display panel 110. For example, the fourth partition part 1701 can be provided between the first area 1 and the fourth area 4 and the third area 3. For example, the fourth partition part 1701 can be provided between the first area 1 and the fourth area 4 and the third area 3 and the sixth area 6. The fifth partition part 1702 can be provided between the second area 2 and the fifth area 5 and the third area 3. For example, the fifth partition part 1702 can be provided between the second area 2 and the fifth area 5 and the third area 3 and the sixth area 6. The fourth partition part 1701 and the fifth partition part 1702 can separate the left and right channels or the left sound and the right sound generated in the sound generation module W1 of the first integrated bass speaker and the fourth sound generation module 1500HL, and the sound generation module W2 of the second integrated bass speaker and the fifth sound generation module 1500HR.

[0579] In order to achieve stereo or stereophonic sound, the fourth sound generation module 1500HL and the fifth sound generation module 1500HR can also be provided, and a partition part should also be provided to separate the channels or sounds generated by the fourth sound generation module 1500HL and the fifth sound generation module 1500HR from the channels or sounds generated by the sound generation module W1 of the first integrated bass speaker, the sound generation module W2 of the second integrated bass speaker, and the third sound generation module 1500C. In the case where the fourth partition part 1701 and the fifth partition part 1702 are provided, the left sound and the right sound or the left and right channels can be separated. A partition part for generating the sound of each sound generation module should be provided so that the top sound or the top channel is separated, and the sound generation module provided in the area on the rear surface of the display panel 110 realizes independent sound for each area.

[0580] The separation part can be configured to separate the top channel and the bottom channel of the display panel 110. For example, the first separation part 1721 can separate the top channel and the bottom channel of the display panel 110. For example, the first separation part 1721 can separate the channels or sounds generated by the fourth sound generation module 1500HL and the fifth sound generation module 1500HR disposed in the upper part of the display panel 110 from the channels or sounds generated by the sound generation module W1 of the first integrated bass speaker, the sound generation module W2 of the second integrated bass speaker, and the third sound generation module 1500C disposed in the lower part of the display panel 110. The second separation part 1722 can be disposed in the lower part of the display panel 110 and can be separated from the driver for driving the display panel 110. For example, the second separation part 1722 can be disposed below the sound generation module W1 of the first integrated bass speaker, the sound generation module W2 of the second integrated bass speaker, and the third sound generation module 1500C. For example, the second separation part 1722 can be separated from the driver for driving the sound generation module W1 of the first integrated bass speaker, the sound generation module W2 of the second integrated bass speaker, the third sound generation module 1500C, and the display panel 110.

[0581] The first separation part 1721, the second separation part 1722, the fourth separation part 1701, and the fifth separation part 1702 can be disposed on the rear cover 300. For example, the first separation part 1721, the second separation part 1722, the fourth separation part 1701, and the fifth separation part 1702 can be disposed on the front surface of the rear cover 300. For example, the first separation part 1721, the second separation part 1722, the fourth separation part 1701, and the fifth separation part 1702 can be disposed between the display panel 110 and the rear cover 300. For example, the first separation part 1721, the second separation part 1722, the fourth separation part 1701, and the fifth separation part 1702 can be disposed between the rear surface of the display panel 110 and the front surface of the rear cover 300.

[0582] The first partition portion 1721, the second partition portion 1722, the fourth partition portion 1701, and the fifth partition portion 1702 may be formed of one or more of a double-sided tape, a double-sided foam tape, a double-sided foam pad, a single-sided tape, a single-sided foam pad, an adhesive, and a bonding member, but are not limited thereto. When each of the first partition portion 1721, the second partition portion 1722, the fourth partition portion 1701, and the fifth partition portion 1702 is formed of a double-sided tape or a double-sided foam pad, the adhesive force can be enhanced during the process of attaching the front surface of the rear cover 300 to the rear surface of the display panel 110. For example, the first partition portion 1721, the second partition portion 1722, the fourth partition portion 1701, and the fifth partition portion 1702 may include a material having elasticity capable of being compressed to a certain extent, and may include, for example, polyurethane, polyolefin, and / or polyethylene, etc., but are not limited thereto.

[0583] Referring to Figure 29B , the first partition portion 1721, the fourth partition portion 1701, and the fifth partition portion 1702 may be provided, and the partition portion 1750 may be provided between the rear cover 300 and the display panel 110. For example, the partition portion 1750 may be provided at the edge or periphery of the rear cover 300. For example, the partition portion 1750 may be provided at the edge or periphery of the front surface of the rear cover 300. The partition portion 1750 may be the entire area of the four outer sides of the front surface of the rear cover 300. As another example, the partition portion 1750 may be provided at the edge or periphery of the rear surface of the display panel 110. The partition portion 1750 may be the entire area of the four outer sides of the rear surface of the display panel 110. The partition portion 1750 may be the entire area of the rear cover 300 or the four outer sides of the rear surface of the display panel 110. For example, the partition portion 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 portion 1750 may be provided along the shape of the display panel 110 to prevent the corrugation phenomenon of the display panel 110. The corrugation phenomenon may be the phenomenon that when the thickness of the substrate configuring the display panel becomes thinner, the shape of the connection portion described above with reference to Figure 4 or Figure 9 bounces up to the screen of the display panel, and the corrugation phenomenon may be the problem that the display panel is uneven or the rear cover is uneven and the screen is seen unevenly. For example, when the partition portion 1750 is the bonding member for attaching the rear cover to the display panel described above with reference to Figure 8 , Figure 10 and Figures 19 to 21 , the above-mentioned reference to Figure 8 , Figure 10 and Figures 19 to 21The described adhesive member, and the partition 1750 can be used as an adhesive member. However, embodiments of the present disclosure are not limited thereto, and an adhesive for attaching the display panel to the rear cover can be provided on the rear surface of the display panel or on the rear cover.

[0584] During the placement of the first partition 1721, the fourth partition 1701, the fifth partition 1702, and the partition 1750, the first partition 1721 can be placed, the partition 1750 can be placed, and then the fourth partition 1701 and the fifth partition 1702 can be placed. As another example, the first partition 1721 can be placed, the fourth partition 1701 and the fifth partition 1702 can be placed, and then the partition 1750 can be placed. However, the order of placing the partitions does not limit the description of the embodiments of the present disclosure. The partition 1750 can be placed first along the length direction of the rear cover and then along the width direction. However, the order of placing the partitions does not limit the description of the embodiments of the present disclosure. In the following embodiments, an example of placing the first partition 1721, placing the partition 1750, and then placing the fourth partition 1701 and the fifth partition 1702 is shown, but embodiments of the present disclosure are not limited thereto. Such a description can be applied to the following embodiments in the same or similar manner.

[0585] Referring to Figure 29C , the shape of the first partition 1721 and the shape of the second partition 1722 can be implemented differently. The shape of the first partition 1721 and the shape of the second partition 1722 can be different from the shape of the display panel 110 or the shape of the fourth partition 1701 and the fifth partition 1702. For example, the first partition 1721 and the second partition 1722 can have a non-flat shape or can not have a linear shape. When the partition has a non-flat shape or does not have a linear shape, the partition can diffuse standing waves. For example, when the partition is implemented as a zigzag shape, a triangular shape, and a rounded-end triangular shape, the standing waves can be diffused in various directions through the zigzag shape, the triangular shape, and the rounded-end triangular shape, thereby enhancing the sound output characteristics. For example, the first partition 1721 and the second partition 1722 can have a zigzag shape, a triangular shape, and a rounded-end triangular shape. For example, the serrations of the partition can be set toward the sound generation module. For example, when the partition has a triangular shape, the end of the triangle can be set toward the sound generation module. For example, when the partition has a rounded-end triangular shape, the end of the rounded-end triangle can be set toward the sound generation module. For example, referring to Figure 29C, when the first partition portion 1721 has an end-rounded triangular shape, the ends of the end-rounded triangle can be arranged facing the fourth sound generation module 1500HL and the fifth sound generation module 1500HR. For example, referring to Figure 29C , when the second partition portion 1722 has an end-rounded triangular shape, the ends of the end-rounded triangle can be arranged facing the sound generation module W1 of the first integrated bass speaker, the sound generation module W2 of the second integrated bass speaker, and the third sound generation module 1500C. Therefore, since the shape of the partition portion is arranged facing at least one sound generation module, it is possible to control the floating or settling phenomenon caused by the standing wave of the sound generation module, and it is possible to reduce the ripple phenomenon of the display panel. In addition, by changing the shape of the partition portion, it is possible to solve sound interference such as diffused reflection of the sound generation module.

[0586] Referring to Figure 29D and Figure 29E , pads can also be provided on at least one side of the partition portion. Standing waves that cause a decrease in sound pressure may occur at the positions where the levels of each of the progressive wave and the reflected wave are the highest. Therefore, the pads can be provided at the positions where the sound waves transmitted from the sound generation module are the strongest. For example, the pads can be provided on one or more sides where the strongest sound waves reach in the partition portion, and can be arranged facing the sound generation module.

[0587] Referring to Figure 29D, the spacer can be disposed on at least one side of the fourth partition portion 1701 to face the sound generation module W1 of the first integrated bass speaker and the fourth sound generation module 1500HL. For example, the 1-3 spacers 713 can be disposed on at least one side of the fourth partition portion 1701 to face the sound generation module W1 of the first integrated bass speaker. The 1-1 spacer 711 can be disposed on the side facing the 1-3 spacers 713. Each of the 1-1 spacer 711 and the 1-3 spacers 713 can be set to one, but is not limited thereto. One of the 1-1 spacer 711 and the 1-3 spacers 713 can be set to two or more. For example, the 4-3 spacer 723 and the 4-4 spacer 724 can be disposed on at least one side of the fourth partition portion 1701 to face the fourth sound generation module 1500HL. The 4-1 spacer 721 and the 4-2 spacer 722 can be disposed on the side facing the 4-3 spacer 723 and the 4-4 spacer 724. Each of the 4-1 spacer 721 to the 4-4 spacers 724 can be set to two, but is not limited thereto. One of the 4-1 spacer 721 to the 4-4 spacers 724 can be set to one or three or more. For example, the 3-1 spacer 911 can be disposed on at least the other side of the fourth partition portion 1701 to face the third sound generation module 1500C. The 3-1 spacer 911 can be set to one or more.

[0588] The spacer can be disposed on at least one side of the fifth partition portion 1702 to face the sound generation module W2 of the second integrated bass speaker and the fifth sound generation module 1500HR. For example, the 2-1 spacer 811 can be disposed on at least one side of the fifth partition portion 1702 to face the sound generation module W2 of the second integrated bass speaker. The 2-3 spacer 813 can be disposed on the side facing the 2-1 spacer 811. In Figure 29D it, each of the 2-1 spacer 811 and the 2-3 spacer 813 can be set to one, but is not limited thereto. One of the 2-1 spacer 811 and the 2-3 spacer 813 can be set to two or more. For example, the 5-1 spacer 821 and the 5-2 spacer 822 can be disposed on at least one side of the fifth partition portion 1702 to face the fifth sound generation module 1500HR. The 5-3 spacer 823 and the 5-4 spacer 824 can be disposed on the side facing the 5-1 spacer 821 and the 5-2 spacer 822. Each of the 5-1 spacer 821 to the 5-4 spacers 824 can be set to two, but is not limited thereto, and one of the 5-1 spacer 821 to the 5-4 824 can be set to one or three or more. For example, the 3-3 spacer 913 can be disposed on at least the other side of the fifth partition portion 1702 to face the third sound generati...
