Description

[Technical Field]

[0001] The present specification relates to a display device. [Background technology]

[0002] A display device includes a display panel that displays images and an audio device that outputs audio related to the images on the display panel. While the screen size of display devices tends to become larger, there is also a growing demand for lighter and slimmer devices. However, since a display device needs to have sufficient space to accommodate an audio device, such as a speaker, for audio output, it is difficult to achieve lighter and smaller devices. Furthermore, since the audio generated by the audio device built into the display device is output toward the back or side of the display device rather than the front of the display panel, it does not travel toward the viewer or user viewing the image in front of the display panel, which can hinder the viewer's immersion in the video.

[0003] The speaker applied to the display device may be, for example, an actuator including a magnet and a coil. However, when an actuator is applied to a display device, it has a drawback in that it is thick. Summary of the Invention [Problem to be solved by the invention]

[0017] Unless otherwise stated, throughout the drawings and detailed description, the same drawing numerals should be understood to refer to the same components, features, and structures. The relative size and depiction of these elements may be exaggerated for clarity, explanation, and convenience. DETAILED DESCRIPTION OF THE INVENTION

[0018] Reference will now be made in detail to the embodiments of the present specification, examples of which may be illustrated in the accompanying drawings. In the following description, if a detailed description of well-known functions or configurations would unnecessarily obscure the gist of the present specification, such detailed description may be omitted for the sake of brevity. The sequence of steps and / or operations described is exemplary, but the order of steps and / or operations is not limited to that described herein and may be modified, except for steps and / or operations that necessarily occur in a particular order. Unless otherwise specified, the same reference numerals may generally refer to similar components even if they are illustrated in different drawings. In one or more embodiments, identical components (or components having the same name) in different drawings may have the same or substantially the same functions and characteristics, unless otherwise specified. The names of the components used in the following description are selected for convenience and may differ from the actual products.

[0019] The advantages and features of the present specification and methods for achieving them will become more apparent from the following detailed description of various examples with reference to the accompanying drawings. However, the present specification is not limited to the embodiment disclosed below, and may be embodied in various different forms. The embodiments of the present specification are provided solely to complete the disclosure of the present specification and to fully convey the scope of the technical idea to those skilled in the art to which the technical idea of ​​the present specification pertains.

[0020] The shapes, sizes, areas, ratios, angles, numbers, etc. disclosed in the drawings for explaining the embodiments of this specification are illustrative only and the present specification is not limited to the illustrated matters.

[0021] When terms such as "comprise," "have," "consist," "comprise," and "formed" are used herein, other terms may be added unless "only" or "only" is used. The terms used herein are used merely to describe particular embodiments and are not intended to limit the scope of the present disclosure. The terms used herein are used merely to describe exemplary embodiments and are not intended to limit the scope of the present disclosure. Terms used in the singular to describe elements include the plural unless otherwise expressly stated. An "embodiment" may be an illustrative example. Any configuration described as an "embodiment" or "example" herein should not necessarily be construed as preferred or advantageous over other configurations.

[0022] In one or more embodiments, components, features, or corresponding information (e.g., levels, ranges, dimensions, sizes, etc.) may be interpreted as including an error or tolerance range even if an explicit description of the error or tolerance range is not provided. The error or tolerance range may be caused by various factors (e.g., process factors, internal or external impact, noise, etc.).

[0023] In the case of a description of a locational relationship, when the locational relationship between two parts is described using words such as "on" or "above" or "over," "on top," "under" or "below," "on bottom," "near," "adjacent to," "beside," or "next to," one or more other parts may be located between the two parts, unless words such as "just," "immediately," "closely," or "directly" are used. For example, when structures are described as being located "above or over," "on top," "under or below," "below," "near," "adjacent to," "beside," or "next to," this description must be interpreted to include cases where the structures touch each other and where a third structure is located between them. For example, when structures are described as being located "above or over," "on top," "under or below," "below," "near," "adjacent to," "beside," or "next to," this description must be interpreted to include cases where the structures touch each other and where a third structure is located between them. Additionally, terms such as "front," "back," "dorsal," "left," "right," "top," "bottom," "downward," "upward," "top," "bottom," "column," "row," "vertical," "horizontal," etc., refer to any frame of reference.

[0024] When describing temporal relationships, if the temporal sequence is described using terms such as "after," "subsequent," "next," or "before, preceding, or prior to," it can also include consecutive or discontinuous situations, as long as terms such as "just," "immediately," or "directly" are not used.

[0025] Although terms such as "first" and "second" are used to describe various components, these components are not limited to these terms. These terms are used merely to distinguish one component from another. Thus, a first component referred to below may also be a second component within the technical spirit of this specification. Furthermore, first elements, second elements, etc. may be arbitrarily named according to the convenience of those skilled in the art without departing from the scope of this specification. Terms such as "first" and "second" may be used to distinguish components from each other, but the function or structure of the components is not limited by the ordinal number preceding the component or the name of the component.

[0026] In describing elements of the present specification, terms such as first, second, A, B, (a), (b), etc. are used to distinguish the elements from other elements, and are not used to define the nature, basis, order, or number of the elements.

[0027] When a component or layer is described as being "connected," "bonded," or "coupled" to another component, it should be understood that the component may be directly connected or coupled to the other component, but that other components or layers may also be "disposed" or "interposed" between each component that may be indirectly connected or coupled unless otherwise expressly stated.

[0028] When a component or layer is described as "contacting" or "overlapping" another component or layer, the component can be in direct contact with or overlaid on the other component or layer, but it should be understood that one or more other components or layers can be "disposed" or "interposed" between each component or layer that is in indirect contact or overlaid unless otherwise explicitly stated. For example, in this specification, terms such as "overlap" and "overlapping" should be understood to mean, for example, "overlapping, electrically and / or physically connected" by surface-to-surface connection, or "overlapping, electrically and / or physically connected" by surface-to-surface connection.

[0029] Terms such as "line" or "direction" should not be interpreted solely in terms of a geometric relationship in which the respective lines or directions are aligned or perpendicular to each other, but may refer to lines or directions having a broader directionality within which the components of this specification can functionally operate.

[0030] The term "at least one" should be understood to include all possible combinations of one or more associated items. For example, the meaning of "at least one of the first, second, and third items" may include only any combination of the first, second, and third items, not just any combination of items presented from two or more of the first, second, or third items.

[0031] The phrase "first component," "second component," and / or "third component" should be understood to mean one of the first, second, and third components, or any or all combinations of the first, second, and third components. For example, A, B, and / or C can be considered as A only, B only, C only, any or some combination of A, B, and C, or all of A, B, and C. Furthermore, the phrase "component A / component B" should be understood to mean component A and / or component B.

[0032] In one or more embodiments, the terms "between" and "in" may be used interchangeably for convenience only, unless otherwise specified. For example, the phrase "between a plurality of components" may also be understood as "among a plurality of components." In other embodiments, the phrase "among a plurality of components" may also be understood as "between a plurality of components." In one or more embodiments, the number of components may be two. In one or more embodiments, the number of components may be more than two.

[0033] In one or more embodiments, the phrase "different from each other" may be understood to mean that any component is different from the other component.

[0034] In one or more embodiments, the expressions "one or more of" and "one or more of" may be used interchangeably for convenience only, unless otherwise specified. For example, the expression "one or more of" can also be understood as "one or more of." For example, the expression "one or more of" can also be understood as "one or more of."

[0035] The features of one or more embodiments of the present specification may be partially or fully combined or combined with each other, and various technical interlocking and driving mechanisms may be possible, and each embodiment may be implemented independently of the other, or may be implemented together in a linked relationship. In one or more embodiments of the present specification, the components of each device according to various embodiments of the present specification may be operably coupled or configured.

[0036] Terms used herein (including technical and scientific terms) may have the same meaning as that understood by a person of ordinary skill in the art to which this specification pertains. Furthermore, terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with the meaning in the context of the relevant art, and should not be interpreted as idealized or overly formal unless otherwise specified.

[0037] The term "device" as used herein may refer to a display device including a display panel and a driver for driving the display panel. Examples of display devices may include light-emitting elements, etc. Further, examples of display devices may include a notebook computer, a television, a computer monitor, an automotive device, a wearable device, an automotive equipment device, and a set electronic device (or apparatus), for example, a mobile electronic device such as a smartphone or electronic pad, which is a complete product or final product including a light-emitting device, although examples of the present specification are not limited thereto.

[0038] For convenience of explanation, the source electrode and the drain electrode are distinguished in the description herein. However, the terms source electrode and drain electrode are used interchangeably. A source electrode may be a drain electrode, and a drain electrode may be a source electrode. Furthermore, a source electrode in one embodiment of the present specification may be a drain electrode in another embodiment of the present specification, and a drain electrode in any embodiment of the present specification may be a source electrode in another embodiment of the present specification.

[0039] Hereinafter, vibration devices, vibration devices, and vehicles including the same according to various embodiments of the present specification will be described in detail with reference to the accompanying drawings. The same reference numbers for components in each drawing may refer to similar components, even if the same components are shown in other drawings, unless otherwise specified. Furthermore, for convenience of explanation, the scales, dimensions, sizes, and thicknesses of the components shown in the drawings may differ from the actual scales, dimensions, sizes, and thicknesses, and therefore are not limited to the scales, dimensions, sizes, and thicknesses shown in the drawings.

[0040] Fig. 1 is a diagram showing a display device according to an embodiment of the present specification. Fig. 2 is a cross-sectional view taken along line II' in Fig. 1. Fig. 3 is a cross-sectional view showing one subpixel configured in the display unit of Fig. 2. All components of each display device according to all embodiments of the present specification can be operably coupled and configured.

[0041] 1 to 3, a display device (or a light-emitting display device or a flexible display device) according to an embodiment of the present disclosure may include a display panel 100 and a vibrating member 200. In the embodiment of the present disclosure, a display panel 100 is disposed on the vibrating member 200. As shown in FIG.

[0042] The display panel 100 is configured to display images and can be configured to output sound based on the vibration of the plate member 150. For example, the display panel 100 can provide sound and / or haptic feedback to the user through vibration.

[0043] A display panel 100 according to an embodiment of the present disclosure may include a base member 110 , a display portion 130 , and a plate member 150 .

[0044] The base member 110 may be made of one or more of a glass material and a plastic material. For example, the base member 110 may be made of a polyimide material. The base member 110 may also include a laminated structure of a glass layer and a plastic layer. For example, the base member 110 may be one or more of a base substrate, a first substrate, a display substrate, a front substrate, a front member, or an external substrate, but the embodiments of the present specification are not limited thereto.

[0045] When a plastic material is used as the material for the base member 110, considering that the components of the display panel are deposited on the base member 110 through a high-temperature deposition process, polyimide, which has excellent heat resistance and can withstand high temperatures, can be used, but the examples in this specification are not limited to this. For example, the plastic material may include any of polyethylene terephthalate (PET), acrylonitrile-butadiene-styrene copolymer (ABS), polymethyl methacrylate (PMMA), polyethylene naphthalate (PEN), polycarbonate (PC), polyethersulfone (PES), polyarylate (PAR), polysulfone (PSF), cycloolefin copolymer (COC), triacetylcellulose (TAC), polyvinyl alcohol (PVA), and polystyrene (PS).

[0046] The entire first surface (or interior surface) of the base member 110 may be covered by one or more buffer layers 111 .

[0047] The buffer layer 111 can prevent materials contained in the base member 110 from diffusing into the transistor layer during high-temperature processes during the manufacturing process of the thin film transistor. The buffer layer 111 can also prevent external moisture or humidity from penetrating into the light emitting device. The buffer layer 111 can be made of an inorganic material.

[0048] The display unit 130 may be configured on the base member 110 or the buffer layer 111. For example, the display unit 130 may be configured on the base member 110 or the buffer layer 111 so as to display an image.

[0049] The display unit 130 may include a plurality of pixels (P) that display an image according to signals supplied to signal lines configured on the base member 110 or the buffer layer 111. For example, the display unit 130 may include a pixel array unit arranged in a pixel area (PA) provided by a plurality of gate lines and / or a plurality of data lines. The pixel array unit may include a plurality of pixels (P) that display an image according to signals supplied to the signal lines. The signal lines may include gate lines, data lines, and pixel driving power lines, but the embodiments of the present specification are not limited thereto.

[0050] Each of the plurality of pixels (P) (or pixel areas (PA)) may include an emissive area (EA) and a non-emissive area (NEA) adjacent to or surrounding the emissive area (EA). The emissive area (EA) may be, but is not limited to, an aperture area, an emissive portion, or an opening. The non-emissive area (NEA) may be a non-emissive portion or a circuit area. Each of the plurality of pixels (P) is the smallest unit area from which light actually emits and may be defined as a subpixel. At least three adjacent pixels (P) may constitute one unit pixel for color display. For example, one unit pixel may include adjacent red, green, and blue pixels, and may further include a white pixel to improve brightness.

[0051] Each of the plurality of pixels (P) may be configured to display an image in a bottom emission manner. In the bottom emission manner, light generated in the pixel (P) may pass through the base member 110 and be emitted toward the rear surface of the base member 110. Alternatively, each of the plurality of pixels (P) may be configured to display an image in a top emission manner or a bottom and top emission manner.

[0052] Each of the plurality of pixels (P) according to an example herein can include a pixel circuit 131, an overcoat layer 133, and a light-emitting element layer (or light-emitting element) .

[0053] The pixel circuit 131 is configured in a non-emission area (NEA) of the pixel (P) together with a signal line and can be connected to adjacent gate lines, data lines, and pixel driving power lines. The pixel circuit 131 can control a current flowing through the light emitting element layer 134 by a data signal from the data line in response to a scan pulse from the gate line based on a pixel driving power supplied from the pixel driving power line. The pixel circuit 131 according to an embodiment of the present specification may include a switching thin film transistor, a driving thin film transistor, and a capacitor, but the embodiment of the present specification is not limited thereto.

[0054] A thin film transistor may include a gate electrode, a gate insulating film, a semiconductor layer, a source electrode, and a drain electrode. Here, the thin film transistor may be an amorphous TFT, a polycrystalline TFT, an oxide TFT, an organic TFT, or the like, but the examples herein are not limited thereto.

[0055] Amorphous TFTs can include amorphous semiconductor materials, which can be made of amorphous silicon (a-Si), although examples herein are not limited thereto.

[0056] Oxide TFTs can include oxide semiconductor materials. Oxide semiconductor materials can have excellent leakage current prevention effects and relatively low manufacturing costs. The oxide semiconductor can be composed of a metal oxide such as zinc (Zn), indium (In), gallium (Ga), tin (Sn), or titanium (Ti), or a combination of metals such as zinc (Zn), indium (In), gallium (Ga), tin (Sn), or titanium (Ti) and their oxides. Specifically, oxide semiconductors can include zinc oxide (ZnO), zinc-tin oxide (ZTO), zinc-indium oxide (ZIO), indium oxide (InO), titanium oxide (TiO), indium-gallium-zinc oxide (IGZO), indium-zinc-tin oxide (IZTO), indium zinc oxide (IZO), indium gallium tin oxide (IGTO), and indium gallium oxide (IGO), but the examples herein are not limited thereto.

[0057] The polycrystalline semiconductor may include a polycrystalline semiconductor material. The polycrystalline semiconductor material has high mobility, such as high mobility of carriers (electrons and holes), low energy consumption, and excellent reliability. The polycrystalline semiconductor may be polysilicon, but the examples of the present specification are not limited thereto.

[0058] The organic TFT can include an organic semiconductor material.

[0059] The switching thin film transistor is switched by a scan pulse supplied to the gate line and supplies a data signal supplied to the data line to the driving thin film transistor. The capacitor is disposed in an overlapping region between the gate electrode and source electrode of the driving thin film transistor and can store a voltage corresponding to the data signal supplied to the gate electrode of the driving thin film transistor. The driving thin film transistor is turned on by the voltage supplied from the switching thin film transistor and / or the voltage of the capacitor, thereby controlling the amount of current flowing from the pixel driving power line to the light emitting element layer 134. For example, the driving thin film transistor controls the data current flowing from the pixel driving power line to the light emitting element layer 134 based on the data signal supplied from the switching thin film transistor, thereby causing the light emitting element layer 134 to emit light with a brightness corresponding to the data signal.

[0060] The display device according to an embodiment of the present specification may further include a scan driving circuit (or gate driving circuit) provided in a non-display area around the display area 130 of the base member 100. The scan driving circuit generates a scan pulse according to a gate control signal and supplies it to the gate line. The scan driving circuit according to an embodiment of the present specification may be configured as a shift register including a transistor formed in the non-display area of ​​the base member 110 by the same process as the thin film transistor, together with the thin film transistor of the pixel (P).

[0061] The pixel circuit 131 may be covered by a passivation layer 132. For example, the passivation layer 132 may be configured on the base member 110 to cover the pixel circuit 131. The passivation layer 132 may be configured of an inorganic material. For example, the passivation layer 132 may include silicon oxide (SiOx) or silicon nitride (SiNx), although examples herein are not limited thereto. For example, the passivation layer 132 may be omitted.

[0062] The overcoat layer 133 may be formed on the base member 110 to cover the pixel circuits 131. The overcoat layer 133 may be configured to provide a flat surface on the pixel circuits 131. For example, the overcoat layer 133 may be made of an organic material. For example, the overcoat layer 133 may include acrylic resin, epoxy resin, phenolic resin, polyamide resin, polyimide resin, etc. For example, the overcoat layer 133 may be a protective layer or a flattening layer, and is not limited to the literal configuration.

[0063] The light emitting element layer 134 may be configured on the overcoat layer 133. The light emitting element layer 134 may include a pixel electrode 134a, a light emitting element 134b, and a common electrode 134c.

[0064] The pixel electrode 134a (or anode electrode) may be formed on the overcoat layer 133, overlapping the entire light-emitting area (EA) and part of the non-light-emitting area (NEA) of each pixel area (PA). For example, the pixel electrode 134a may be formed in a pattern. The pixel electrode 134a may be electrically connected to a driving thin film transistor of the pixel circuit 131 through a contact hole formed in the overcoat layer 133. The pixel electrode 134a may be made of a transparent conductive material such as ITO (indium tin oxide) or IZO (indium zinc oxide), but the embodiments of the present specification are not limited thereto. Alternatively, the pixel electrode 134a may have a multi-layer structure including a transparent conductive film with high reflective efficiency and an opaque conductive film. The transparent conductive film may be made of a material with a relatively high work function, such as ITO (indium tin oxide) or IZO (indium zinc oxide). The opaque conductive film may have a single layer or multi-layer structure containing Al, Ag, Cu, Pb, Mo, Ti, or an alloy thereof. For example, the pixel electrode 134a may have a structure in which a transparent conductive film, an opaque conductive film, and a transparent conductive film are sequentially stacked, or a structure in which a transparent conductive film and an opaque conductive film are sequentially stacked, but the embodiments of the present specification are not limited thereto.

[0065] The edge portions of the pixel electrodes 134a arranged in part of the non-light-emitting area (NEA) of each pixel area (PA) may be covered by a bank layer 135. The bank layer 135 may be provided on the overcoat layer 133 so as to cover the edge portions of the pixel circuits 131 and the pixel electrodes 134a, thereby defining (or partitioning) the light-emitting areas (EA) (or aperture areas or light extraction areas) of each of the multiple pixels (P). The bank layer 135 may be made of an opaque material (e.g., a black material) to prevent optical interference between adjacent pixels. In this case, the bank layer 135 may be made of at least one of a color pigment, organic black, black ink, and carbon.

[0066] The light-emitting element 134b may be formed or configured on the pixel electrode 134a. The light-emitting element 134b may be configured to be in direct contact with the pixel electrode 134a. For example, the light-emitting element 134b may include an organic light-emitting element or an inorganic light-emitting element. For example, the light-emitting element 134b may include any one of an organic light-emitting layer, an inorganic light-emitting layer, and a quantum dot light-emitting layer, or may include a stacked or mixed structure of an organic light-emitting layer (or an inorganic light-emitting layer) and a quantum dot light-emitting layer.

[0067] The common electrode 134c (or cathode electrode) may be configured to be commonly connected to the light emitting elements 134b provided in each of the plurality of pixels (P). The common electrode 134c may include a metal material with high reflectivity to reflect incident light emitted from the light emitting elements 134b toward the base member 110.

[0068] The light-emitting element 134b according to the embodiments of the present specification may be realized to emit light of the same color, for example, white, for each pixel, or may be realized to emit light of different colors, for example, red, green, or blue, for each pixel. In the embodiments of the present specification, the light-emitting element 134b may be a single structure containing the same color for each pixel, or a stack structure including two or more structures. In other embodiments of the present specification, the light-emitting element 134b may be a stack structure including two or more structures containing one or more other colors for each pixel.

[0073] The display panel 100 or the display unit 130 according to an embodiment of the present disclosure may further include an encapsulation layer 136 .

[0074] The encapsulation layer 136 may be configured to surround and cover the display unit 130. The encapsulation layer 136 may be configured to prevent external moisture or humidity from penetrating into the light emitting element layer 134. The encapsulation layer 136 may be formed of an inorganic material layer or an organic material layer, or may have a multi-layer structure in which inorganic material layers and organic material layers are alternately stacked.

[0075] For example, the encapsulation layer 136 can include a first inorganic encapsulation layer, a second organic encapsulation layer, and a third inorganic encapsulation layer stacked in sequence.

The adhesive member may be configured on the base member 110 to surround the display unit 130. A first surface of the plate member 150 may be bonded (or attached) to the adhesive member or directly bonded (or attached) to the adhesive member 140. As a result, the display unit 130 may be surrounded by the base member 110 and the adhesive member 140, and thus embedded or built-in between the base member 110 and the adhesive member 140. For example, a second surface 150a of the plate member 150 opposite the first surface may be the front surface (or screen) of the display panel 100 exposed to the outside of the display device.

[0082] The plate member 150 can dissipate heat generated in the display panel 100. The plate member 150 can protect the display unit 130 or the display panel 100 from external impact and prevent external moisture or humidity from penetrating into the light emitting element layer 134.

For example, the vibration transmission medium can include a piezoelectric material contained in or added to the adhesive member 140, but the embodiments of the present specification are not limited thereto.

[0085] The vibration member 200 can be configured to vibrate the display panel 100 or the plate member 150. The vibration member 200 can be configured directly on the display panel 100 or directly connected to the rear surface of the display panel 100. For example, the vibration member 200 can be integrated into the display panel 100. For example, the display panel 100 can be a display panel with an integrated vibration device.

[0086] The vibrating member 200 may include the plate member 150 of the display panel 100. The plate member 150 of the display panel 100 may be used as an electrode of the vibrating member 200.

[0087] The vibrating member 200 according to an embodiment of the present specification can vibrate the display panel 100 (or the plate member 150) by vibrating in the thickness direction (Z) through alternately repeating contraction and / or expansion due to the piezoelectric effect. For example, the vibrating member 200 can directly vibrate the display panel 100 (or the plate member 150) by vibrating in the thickness direction (Z) through alternately repeating contraction and / or expansion due to the inverse piezoelectric effect.

[0088] A vibration member 200 according to an embodiment of the present disclosure may include a first electrode 150 , a vibration layer 210 , and a second electrode 230 .

[0089] The first electrode 150 may be formed as a plate member 150 of the display panel 100. For example, the first electrode (or plate member) 150 may be a conductive substrate, a conductive plate, a metal electrode, an electrode member, an electrode plate, a lower electrode, a lower electrode plate, a common electrode member, or a common electrode.

[0090] The vibration layer 210 may be configured on a second surface of the first electrode 150 opposite to the first surface of the first electrode 150 corresponding to the first surface of the plate member 150. The vibration layer 210 may be formed directly on or directly coupled to the second surface of the first electrode 150. In the following description, the "first electrode 150" may mean the "first electrode (or plate member) 150."

[0091] The vibration layer 210 may include a piezoelectric material or an electroactive material that exhibits the piezoelectric effect. For example, a piezoelectric material may have the property that, when pressure or torsion is applied to a crystal structure by an external force, a potential difference is generated by dielectric polarization due to a change in the relative positions of positive (+) ions and negative (-) ions, and vibration is generated by an electric field due to an inversely applied voltage. For example, the vibration layer 210 may be a piezoelectric layer, a piezoelectric material layer, an electroactive layer, a piezoelectric material portion, an electroactive portion, a piezoelectric structure, a piezoelectric ceramic, a vibration portion, a vibration generating portion, a displacement portion, a displacement generating portion, a sound generating portion, or an active vibration portion.

[0092] The vibration layer 210 may be made of a ceramic-based material that can achieve relatively high vibration, or may be made of a piezoelectric ceramic having a perovskite-based crystal structure.

[0093] The piezoelectric ceramic may be composed of a single-crystal ceramic having a single crystal structure, or a ceramic material having a polycrystalline structure or a polycrystalline ceramic. The single-crystal ceramic piezoelectric material may include, but is not limited to, α-AlPO4, α-SiO2, LiNbO3, Tb2(MoO4)3, Li2B4O7, or ZnO. The polycrystalline ceramic piezoelectric material may include, but is not limited to, a PZT (lead zirconate titanate)-based material containing lead (Pb), zirconium (Zr), and titanium (Ti), or a PZNN (lead zirconate nickel niobate)-based material containing lead (Pb), zirconium (Zr), nickel (Ni), and niobium (Nb). For example, the vibration layer 210 may include at least one of lead-free CaTiO3, BaTiO3, and SrTiO3, but is not limited to, the embodiment of the present specification.

[0094] The vibration layer 210 may be configured on the second surface 150a of the plate member 150 through a process prior to the bonding process between the plate member 150 and the display unit 130. The first surface of the vibration layer 210 may be bonded to or in contact with the second surface 150a of the plate member 150. For example, the first surface of the vibration layer 210 may be electrically bonded to or in electrical contact with the second surface 150a of the plate member 150.

[0095] The vibration layer 210 may include three or more polygonal shapes, a circular shape, or an elliptical shape, and the vibration layer 210 may include a non-rectangular shape, and examples herein are not limited thereto. For example, the non-rectangular shape may include one or more straight lines and one or more curves having curvature, and examples herein are not limited thereto.

[0096] The vibration layer 210 according to an embodiment of the present specification may be formed or realized on the second surface 150a of the first electrode 150 by a tape casting method. For example, the vibration layer 210 may be formed on the second surface 150a of the plate member 150 by a tape casting process (or method) using a piezoelectric material on the plate member 150 in a process prior to a bonding process between the plate member 150 and the display unit 130 or in a manufacturing process of the plate member 150.

[0097] According to one embodiment of the present specification, the vibration layer 210 may be formed (or manufactured) through a process of preparing a slurry containing a piezoelectric powder (or ceramic powder) and an additive, applying (or tape-casting or forming) the slurry to the second surface of the plate member 150, and molding (or sintering) the applied (or formed) slurry at least once. For example, the additive added to the slurry may include a substance or material known in the field of piezoelectric material compositions, and the present specification is not limited thereto. For example, the additive may include one or more of a dispersant, a solvent, a binder, and a plasticizer.

[0098] According to one embodiment of the present disclosure, the binder may include a high-temperature binder. For example, the binder may include glass frit. The binder may remain in a particulate state on the second surface of the plate member 150 when the slurry dries. The binder changes to a liquid state when the piezoelectric particles (or ceramic particles) grow at the molding (or sintering) temperature of the slurry, moves to the interface between the plate member 150 and the piezoelectric material, and solidifies as the molding temperature decreases, thereby increasing the bonding (or adhesive) strength between the plate member 150 and the piezoelectric material. For example, the content of the glass frit may be 1 wt% to 12 wt%, and preferably, the content of the glass frit may be 3 wt% to 10 wt%, although the present disclosure is not limited thereto. The glass frit may include a PbO- or Bi2O3-based material, although the present disclosure is not limited thereto.

[0099] The vibration layer 210 according to one embodiment of the present specification is formed on the second surface 150a of the first electrode 150 by a tape casting method, and is not limited to a specific shape and may include three or more polygonal shapes, a circular shape, or an elliptical shape, and the vibration layer 210 may include a non-rectangular shape including one or more straight lines and one or more curves having curvature.

[0100] According to one embodiment of the present specification, the vibrating layer 210 may overlap the display unit 130 of the display panel 100. For example, the vibrating layer 210 may have a size corresponding to that of the display unit 130 of the display panel 100. For example, the size of the vibrating layer 210 may be the same as or smaller than that of the display unit 130. For example, the size of the vibrating layer 210 may be 0.9 to 1.1 times the size of the display unit 130, and preferably 0.9 to 1 times the size of the display unit 130, although the embodiment of the present specification is not limited thereto. For example, the size of the vibrating layer 210 may be the same as or approximately the same as that of the display unit 130 of the display panel 100, thereby covering most of the area of ​​the display panel 100. Furthermore, vibrations generated from the vibrating layer 210 can vibrate the entire area of ​​the display panel 100, thereby improving the sense of sound localization and improving user satisfaction. In addition, since the contact area (or panel coverage) between the display panel 100 and the vibrating member 200 can be increased, the vibration area of ​​the display panel 100 can be increased, and the mid-low frequency range sound generated by the vibration of the display panel 100 can be improved.

[0101] The second electrode 230 may be configured on or coupled to the second surface 210a of the vibration layer 210. This allows the vibration layer 210 to vibrate in response to a signal (or voltage or vibration drive signal) applied to the plate member 150 of the display panel 100 and the second electrode (or electrode layer) 230.

[0102] The second electrode 230 may have the same or substantially the same size as the vibration layer 210, or may have a smaller size than the vibration layer 210. For example, the second electrode 230 may have the same shape as the vibration layer 210, although examples herein are not limited thereto. For example, the second electrode 230 may be an electrode layer, an upper electrode, an upper electrode layer, an individual electrode, an individual electrode layer, a patterned electrode, or a patterned electrode layer.

[0103] According to one embodiment of the present specification, in order to prevent an electrical connection (or short circuit) between the first electrode 150 and the second electrode 230, the second electrode 230 may be formed on the remaining portion of the second surface 210a of the vibration layer 210 excluding the periphery portion. For example, the second electrode layer 230 may be formed on the entire remaining first surface 210a of the vibration layer 210 excluding the periphery portion. For example, the distance between the side surface (or outer wall) of the second electrode 230 and the side surface (or outer wall) of the vibration layer 210 may be at least 0.5 mm or more. For example, the distance between the side surface of the second electrode 230 and the side surface of the vibration layer 210 may be at least 1 mm or more, although the embodiment of the present specification is not limited thereto.

[0104] According to an embodiment of the present specification, the second electrode 230 may be made of a transparent conductive material, a semi-transparent conductive material, or an opaque conductive material. For example, the transparent or semi-transparent conductive material of the second electrode 230 may include, but is not limited to, ITO (indium tin oxide) or IZO (indium zinc oxide). The opaque conductive material may include, but is not limited to, gold (Au), silver (Ag), platinum (Pt), palladium (Pd), molybdenum (Mo), magnesium (Mg), carbon, or silver (Ag) containing glass frit, or an alloy thereof, but is not limited to ...

[0105] In the second electrode 230 made of silver (Ag) containing glass frit, the content of the glass frit may be 1 wt% to 12 wt%, preferably 3 wt% to 10 wt%, although the embodiment of the present specification is not limited thereto. The glass frit may include a PbO or Bi2O3-based material, although the embodiment of the present specification is not limited thereto. As a result, the bonding strength (or adhesive strength) between the first surface of the second electrode 230 and the second surface 210a of the vibration plate 210 may be increased by the glass frit.

[0106] The vibrating layer 210 may be poled by a constant voltage applied to the first electrode 150 and the second electrode 230 in a constant temperature environment or in a temperature environment that changes from a high temperature to a room temperature, but the embodiments of the present specification are not limited thereto. For example, the vibrating layer 210 may vibrate by alternately repeating contraction and / or expansion due to an inverse piezoelectric effect caused by a drive signal externally applied to the first electrode 150 and the second electrode 230. For example, the vibrating layer 210 may vibrate by vibrating in a vertical direction and / or a planar direction according to the drive signal applied to the first electrode 150 and the second electrode 230. As a result, the contraction and / or expansion of the vibrating layer 210 in the planar direction may increase or improve the displacement of the vibrating member 200 or the display panel 100 (or the plate member 150).

[0107] The display or vibration member 200 according to an embodiment of the present disclosure may further include a cover member 270 .

[0108] The cover member 270 may be configured to protect the vibration layer 210 and the second electrode 230. The cover member 270 may be configured to surround and cover the vibration layer 210 and the second electrode 230. For example, the cover member 270 may be a cover film, a cover layer, a protective member, or a protective layer. For example, the cover member 270 may be a polyimide (PI) film, a polyethylene terephthalate (PET) film, a polyethylene naphthalate (PEN) film, or the like, but examples of the present specification are not limited thereto.

[0109] The cover member 270 may be connected or bonded to the second surface of the second electrode 230 via the adhesive layer 250. For example, the cover member 270 may be connected or bonded to the second electrode 230 by a film lamination process using the adhesive layer 250.

[0110] The adhesive layer 250 may be disposed between the second electrode 230 and the cover member 270. For example, the adhesive layer 250 may be configured or interposed between the first electrode 150 and the cover member 270 to encase or surround the vibration layer 210 and the second electrode 230. For example, the adhesive layer 250 may be configured or filled between the first electrode 150 and the cover member 270 to completely encase the second surface of the second electrode 230 and each side surface of the vibration layer 210. For example, the vibration layer 210 and the second electrode 230 may be embedded or built-in between the first electrode 150 and the adhesive layer 250.

[0111] The adhesive layer 250 may include an electrically insulating material that is compressible and resilient while having adhesive properties, such as epoxy resin, acrylic resin, silicone resin, or urethane resin, but the embodiments of the present specification are not limited thereto.

[0112] In one embodiment of the present specification, the vibration member 200 uses the plate member 150 of the display panel 100 as the first electrode 150, thereby eliminating the need for a separate first electrode and slimming down the thickness of the omitted first electrode, thereby reducing the thickness of the display device.

For example, the adhesive layer of the panel connecting member 450 may include an epoxy-based, acrylic-based, silicone-based, or urethane-based adhesive material, although the embodiments of the present specification are not limited thereto. For example, the adhesive layer of the panel connecting member 450 may include a urethane-based material, which has relatively softer properties than an acrylic-based material, among acrylic-based and urethane-based materials, in order to minimize transmission of vibrations of the display panel 100 to the support member 300. This may minimize vibrations of the display panel 100 transmitted by the support member 300.

[0130] When a display device according to an embodiment of the present disclosure includes a panel connecting member 450 instead of a middle frame 400, the support member 300 may include a curved sidewall that is bent from one side (or end) of the second support member 330 and surrounds the outer surface (or outer wall) of the display panel 100. The curved sidewall according to an embodiment of the present disclosure may have a single sidewall structure or a hemming structure. A hemming structure may be a structure in which the end of a member is bent into a curved shape and overlaps or is spaced apart from each other. For example, to improve the aesthetic appeal of the side design, the curved sidewall may include a first curved sidewall that is bent from one side (or end) of the second support member 330 and a second curved sidewall that is bent from the first curved sidewall to between the first curved sidewall and the outer surface of the display panel 100. The second bent side wall may be in contact with the inner surface of the first bent side wall or may be spaced apart from the inner surface of the first bent side wall so as to reduce the transmission of an external impact in the lateral direction to the outer surface of the display panel 100. Thus, the second bent side wall may prevent the outer surface of the display panel 100 from contacting the inner surface of the first bent side wall or reduce the transmission of an external impact in the lateral direction to the outer surface of the display panel 100.

[0131] A display device according to an embodiment of the present specification can output sound in the forward direction (FD) of the display panel 100 by generating vibration sound and / or sound due to vibration of the display panel 100 based on vibration of the vibrating member 200 configured on the plate member 150 of the display panel 100. Furthermore, by using the plate member 150 of the display panel 100 to protect the display unit 130 from external impact and as an electrode of the vibrating member 200, the display device according to an embodiment of the present specification can be made thinner or slimmer by reducing the thickness of the vibrating member 200. Therefore, the display device according to an embodiment of the present specification can output sound in the forward direction (FD) of the display panel 100 and can be made slimmer.

[0132] Fig. 5 is a diagram illustrating a rear surface of a display panel and a vibrating member in a display device according to an embodiment of the present disclosure, and Fig. 6 is a cross-sectional view taken along line II-II' in Fig. 5 according to an embodiment of the present disclosure.

[0133] 5 and 6, the display device according to an embodiment of the present specification may further include a panel driving circuit 170 and a signal cable 500.

[0134] The panel driving circuit 170 may be configured to be electrically connected to the display panel 100. The panel driving circuit 170 may be disposed on the rear surface of the display panel 100 and electrically connected to a pad unit 138 configured on the display panel 100.

[0135] The pad unit 138 may be disposed on one side of the display panel 100. For example, the pad unit 138 may be disposed on one side edge of the display panel 100. For example, the pad unit 138 may include a plurality of pads 138p electrically connected to signal lines configured on the display panel 100.

[0136] A panel driving circuit 170 according to one embodiment of the present disclosure may include a plurality of flexible films 171 , a plurality of data driving integrated circuits 173 , and one or more printed circuit boards 175 .

[0137] Each of the flexible films 171 may be attached to the pad portion 138 of the display panel 100 by a film attachment process. Each of the flexible films 171 may be disposed on the rear surface of the display panel 100.

[0138] Each of the plurality of data driving integrated circuits 173 may be individually mounted on each of the plurality of flexible films 171. Each of the plurality of data driving integrated circuits 173 may receive pixel data and a timing control signal provided from a display control circuit, convert the pixel data into an analog pixel-specific data signal according to the timing control signal, and output the converted pixel data. The pixel-specific data signal may be supplied to a data line of the display unit 130 via the flexible film 171 and the pad unit 138.

[0139] One or more printed circuit boards 175 may be connected to the multiple flexible films 171 and disposed on the rear surface of the display panel 100. For example, the one or more printed circuit boards 175 may be disposed so as to overlap an edge portion of one side of the rear surface of the display panel 100 or so as to overlap the plate member 150. The one or more printed circuit boards 175 may be configured to transmit signals and power between components of the panel drive circuit 170. For example, the one or more printed circuit boards 175 may be connected (or attached) to the second surface (or rear surface) 500a of the plate member 150 via a buffer member 180. The buffer member 180 may be made of a material that can block or minimize transmission of vibrations of the plate member 150 to the printed circuit board 175. For example, the buffer member 180 may be a double-sided tape or a double-sided cushion tape, and the partition member 610 may block vibrations generated in a first region (A1) of the display panel 100 by the first vibrating member 200-1 from being transmitted to a second region (A2) of the display panel 100, or may block vibrations generated in the second region (A2) of the display panel 100 by the second vibrating member 200-2 from being transmitted to the first region (A1) of the display panel 100. Thus, the partition member 610 attenuates or absorbs vibrations of the display panel 100 at the center of the display panel 100, thereby blocking sound in the first region (A1) from being transmitted to the second region (A2) or sound in the second region (A2) from being transmitted to the first region (A1). Therefore, the partition member 610 can further improve the sound output characteristics of the display device by separating left and right sounds, and thus the display device according to the embodiments of the present specification can output two-channel stereo sound toward the front of the display panel 100 by separating left and right sounds by the partition member 610.

[0140] The signal cable 500 may be disposed on the rear surface of the display panel 100 so as to be electrically coupled to the vibrating member 200. For example, the signal cable 500 may be configured to be electrically coupled to the plate member 150 of the display panel 100. For example, the signal cable 500 may be configured to be electrically coupled to the first electrode 150 and the second electrode 230, which are the plate member of the vibrating member 200. For example, the signal cable 500 may be integrated with the vibrating member 200. For example, a portion of the signal cable 500 adjacent to the vibrating layer 210 may be integrated with the vibrating member 200 by being inserted (or housed) in the adhesive layer 250 between the plate member 150 and the cover member 270. This allows the vibrating member 200 to vibrate in response to a signal applied from the plate member 150 and the signal cable 500.

[0141] The signal cable 500 according to an embodiment of the present disclosure may include a wiring portion 510 , a first contact line 511 , a second contact line 513 , and a terminal portion 530 .

[0142] The wiring unit 510 may be disposed on the rear surface of the display panel 100. A portion or one side edge of the wiring unit 510 may be inserted (or housed) in the vibrating member 200 or may be integrated with the vibrating member 200. For example, a portion or one side edge of the wiring unit 510 may be covered by the cover member 270 of the vibrating member 200. For example, a portion or one side edge of the wiring unit 510 may be inserted (or housed) in the adhesive layer 250 of the vibrating member 200, thereby being fixed to the vibrating member 200 or being integrated with the vibrating member 200. This may reduce or minimize poor contact between the vibrating member 200 and the signal cable 500 due to movement or bending of the signal cable 500.

[0143] The wiring unit 510 may include a base film, a wiring layer having first and second signal lines formed on the base film, and an insulating layer covering the wiring layer.

[0144] The first contact line 511 may be configured to be electrically connected to (or in contact with) the first electrode (or plate member) 150 of the vibrating member 200. For example, the first contact line 511 may be a portion of the first signal line exposed at an edge portion of one side of the wiring unit 510, or a first finger line (or first protruding signal line) extending (or protruding) to a certain length from the first signal line of the wiring unit 510. According to one embodiment of the present specification, the first contact line 511 may be electrically connected to (or in contact with) the first electrode (or plate member) 150 of the vibrating member 200, or may be electrically connected to (or in contact with) the first electrode (or plate member) 150 of the vibrating member 200 directly. According to other embodiments of the present specification, the first contact line 511 may be electrically connected to (or in contact with) the first electrode (or plate member) 150 of the vibrating member 200 via a conductive double-sided tape or an anisotropic conductive film. The first contact line 511 can be fixed to or integrated with the vibration member 200 by being covered by the cover member 270 of the vibration member 200, thereby minimizing poor contact between the vibration member 200 and the signal cable 500 due to movement or bending of the signal cable 500.

[0145] According to one embodiment of the present specification, the vibrating member 200 uses the plate member 150 of the display panel 100 as the first electrode 150, so that the contact portion (or contact area) between the first contact line 511 and the plate member 150 is not limited to a specific position on the second surface 150a of the plate member 150. For example, the contact portion (or contact area) between the first contact line 511 and the plate member 150 can be adjacent to the vibrating layer 210 or the second electrode 230 of the vibrating member 200, thereby shortening or minimizing the length of the signal cable 500.

[0146] The second contact line 513 may be configured to be electrically connected to (or in contact with) the second electrode 230 of the vibrating member 200. The second contact line 513 may protrude from one edge portion of the wiring unit 510 onto the second electrode 230 of the vibrating member 200. For example, the second contact line 513 may be a portion of the second signal line exposed at a protruding wiring unit that protrudes from one edge portion of the wiring unit 510 onto the second electrode 230 of the vibrating member 200, or may be a second finger line (or a second protruding signal line) that protrudes to have a certain length from the second signal line of the wiring unit 510.

[0147] According to one embodiment of the present specification, the second contact line 513 may be electrically connected (or in contact with) or directly connected (or in contact with) the second electrode 230 of the vibrating member 200. According to another embodiment of the present specification, the second contact line 513 may be electrically connected (or in contact with) the second electrode 230 of the vibrating member 200 via a conductive double-sided tape or an anisotropic conductive film. The second contact line 513 may be fixed to or integrated with the vibrating member 200 by being covered by the cover member 270 of the vibrating member 200, thereby reducing or minimizing poor contact between the vibrating member 200 and the signal cable 500 due to movement or bending of the signal cable 500.

[0148] The terminal portion 530 may be configured on the other edge portion of the wiring portion 510. The terminal portion 530 may be configured to expose a portion of each of the first and second signal lines arranged on the other edge portion of the wiring portion 510. For example, the terminal portion 530 may be electrically coupled to a vibration drive circuit (or an acoustic processing circuit) or may include a connector electrically coupled to the vibration drive circuit (or an acoustic processing circuit).

[0149] The signal cable 500 is electrically coupled to the first electrode (or plate member) 150 and the second electrode 230, thereby enabling the first and second vibration drive signals supplied from the vibration drive circuit (or acoustic processing circuit) via the terminal portion 530 to be applied or transmitted to the first electrode (or plate member) 150 and the second electrode 230 of the vibration member 200.

[0150] The vibration member 200 according to one embodiment of the present specification can vibrate the plate member 150 or the display panel 100 by vibrating in response to a vibration drive signal (or acoustic signal) applied to the first electrode (or plate member) 150 and the second electrode 230 via the signal cable 500.

[0151] FIG. 7 is a diagram showing a display device according to another embodiment of the present specification. FIG. 8 is a cross-sectional view taken along line III-III' in FIG. 7 according to another embodiment of the present specification. FIGS. 7 and 8 show modifications of the vibrating member described with reference to FIGS. 1 to 6. Therefore, in the following description, the modified configuration will be described in detail, and the remaining configuration will be given the same reference numerals as FIGS. 1 to 6, and redundant description thereof will be omitted or will be briefly described.

[0152] 7 and 8, in a display device according to another embodiment of the present disclosure, the vibrating member 200 may include a plurality of vibrating members 200-1 and 200-2. For example, the vibrating member 200 may include a first vibrating member 200-1 and a second vibrating member 200-2.

[0153] The first vibrating member 200-1 may be configured in a first region (A1) of the display panel 100. For example, the first region (A1) of the display panel 100 may be a first rear region, a left region, or a rear left region. According to one embodiment of the present specification, the first vibrating member 200-1 may be configured to have a size (or area) smaller than the first region (A1) of the display panel 100. For example, the first vibrating member 200-1 may be configured to have a square shape within the first region (A1) of the display panel 100. The first vibrating member 200-1 may be configured similarly to the vibrating member 200 described with reference to FIGS. 1 to 6, except that it is configured in the first region (A1) of the display panel 100. For example, the first vibrating member 200-1 uses the plate member 150 of the display panel 100 as a first electrode and includes a vibrating layer 210 coupled (or configured) to a portion of the first region (A1) of the plate member 150, a second electrode 230 coupled to the vibrating layer 210, and a cover member 270 covering the vibrating layer 210 and the second electrode 230, so redundant explanations thereof will be omitted.

[0154] The first vibrating member 200-1 can vibrate the first region (A1) of the display panel 100 by vibrating in response to a signal applied from the plate member 150 and the signal cable (or first signal cable) 500. For example, the first vibrating member 200-1 can vibrate the first region (A1) of the plate member 150 or the display panel 100 by vibrating in response to a vibration drive signal (or an acoustic signal) applied to the first electrode (or plate member) 150 and the second electrode 230 via the signal cable 500. For example, the first region (A1) of the plate member 150 or the display panel 100 can vibrate in response to the vibration of the first vibrating member 200-1 to generate a first sound (or first haptic feedback) or a left sound (or left haptic feedback), and thereby the first sound (or left sound) can be output in the front direction of the display panel 100.

[0155] The second vibrating member 200-2 may be configured in the second region (A2) of the display panel 100. For example, the second region (A2) of the display panel 100 may be a second rear region, a right region, or a rear right region. According to one embodiment of the present specification, the second vibrating member 200-2 may be configured to have a size (or area) smaller than the second region (A2) of the display panel 100. For example, the second vibrating member 200-2 may be configured to have a square shape in the second region (A2) of the display panel 100. The second vibrating member 200-2 may be configured similarly to the vibrating member 200 described with reference to FIGS. 1 to 6, except that it is configured in the second region (A2) of the display panel 100. For example, the second vibrating member 200-2 uses the plate member 150 of the display panel 100 as a first electrode and includes a vibrating layer 210 coupled (or configured) to a portion of the second region (A2) of the plate member 150, a second electrode 230 coupled to the vibrating layer 210, and a cover member 270 covering the vibrating layer 210 and the second electrode 230, so redundant explanations thereof will be omitted.

[0156] The second vibrating member 200-2 can vibrate the second region (A2) of the display panel 100 by vibrating in response to a signal applied from the plate member 150 and the signal cable (or second signal cable) 500. For example, the second vibrating member 200-2 can vibrate the second region (A2) of the plate member 150 or the display panel 100 by vibrating in response to a vibration drive signal (or an acoustic signal) applied to the first electrode (or plate member) 150 and the second electrode 230 via the signal cable 500. For example, the second region (A2) of the plate member 150 or the display panel 100 can vibrate in response to the vibration of the second vibrating member 200-2, thereby generating a second sound (or a second haptic feedback) or a right sound (or a right haptic feedback), and the second sound (or a right sound) can be output in the front direction of the display panel 100.

[0157] The plate member 150 of the display panel 100 is used as a first electrode of each of the first vibrating member 200-1 and the second vibrating member 200-2, and can receive a first vibration driving signal from a first signal line of a signal cable 500 connected to each of the first vibrating member 200-1 and the second vibrating member 200-2. For example, the first vibration driving signal can be a first acoustic signal, a common acoustic signal, a lower electrode signal, a common electrode signal, or a negative polarity vibration signal, but the embodiments of the present specification are not limited thereto.

[0158] The first vibrating member 200-1 and the second vibrating member 200-2 may be configured symmetrically with respect to the midpoint between the first area (A1) and the second area (A2) of the display panel 100 (or the partition member 610), but are not limited thereto and may be configured asymmetrically.

[0159] A display device according to another embodiment of the present disclosure may further include a partition 600 that divides the display panel 100 into a first area (A1) and a second area (A2).

[0160] The partition 600 may be an air gap or space through which sound is generated when the display panel 110 is vibrated by the first vibrating member 200-1 and the second vibrating member 200-2. For example, the partition 600 may separate sounds or separate channels, thereby preventing or reducing degradation of acoustic characteristics due to acoustic interference. The partition 600 may be disposed between the display panel 100 and the support member 300. For example, the partition 600 may be disposed between the rear surface of the display panel 100 and the front surface of the support member 300. The partition 600 may be disposed on the support member 300 to reduce the effect of the partition 600 on the image quality of the display panel 100. The partition 600 may be referred to as a sound-blocking member, a sound-separating member, a space-separating member, an enclosure, a baffle, or the like, and the embodiments of the present specification are not limited to these terms.

[0161] The partition 600 according to embodiments herein may include a partition member (or first partition member) 610 disposed between the first and second vibrating members 200-1, 200-2.

[0162] The partition member 610 may be disposed between the first area (A1) and the second area (A2) of the display panel 100. The partition member 610 may be disposed between the plate member 150 and the support member 300, which are located between the first area (A1) and the second area (A2) of the display panel 100. For example, the partition member 610 may be disposed between the rear surface of the plate member 150 and the support member 300, which are located between the first area (A1) and the second area (A2) of the display panel 100. The partition member 610 can separate a first sound generated by the first vibrating member 200-1 from a second sound generated by the second vibrating member 200-2. For example, the partition member 610 can block vibrations generated in the first region (A1) of the display panel 100 by the first vibrating member 200-1 from being transmitted to the second region (A2) of the display panel 100, or can block vibrations generated in the second region (A2) of the display panel 100 by the second vibrating member 200-2 from being transmitted to the first region (A1) of the display panel 100. Thus, the partition member 610 can attenuate or absorb the vibrations of the display panel 100 at the center of the display panel 100, thereby blocking sound in the first region (A1) from being transmitted to the second region (A2) or sound in the second region (A2) from being transmitted to the first region (A1). Therefore, the partition member 610 can further improve the sound output characteristics of the display device by separating left and right sounds, and thus the display device according to the embodiments of the present specification can output two-channel stereo sound toward the front of the display panel 100 by separating left and right sounds by the partition member 610.

[0163] A partition 600 according to embodiments herein may include a second partition member 620 surrounding the first vibrating member 200-1 and a third partition member 630 surrounding the second vibrating member 200-2.

[0164] The second partition member 620 may be disposed between the first region (A1) of the display panel 100 and the support member 300 to surround the first vibrating member 200-1. The second partition member 620 may be disposed between the first region (A1) of the display panel 100 and the support member 300 to be spaced a certain distance from the first vibrating member 200-1. The second partition member 620 may form a first air gap (AG1) surrounding the first vibrating member 200-1 between the display panel 100 and the support member 300. For example, the second partition member 620 may be disposed between the first region (A1) of the plate member 150 corresponding to the first region (A1) of the display panel 100 and the support member 300. For example, the second partition member 620 may define or limit the vibration region (or vibration area) of the first region (A1) of the display panel 100 caused by the first vibrating member 200-1.

[0165] The third partition member 630 may be disposed between the second region (A2) of the display panel 100 and the support member 300 to surround the second vibrating member 200-2. The third partition member 630 may be disposed between the second region (A2) of the display panel 100 and the support member 300 to be spaced a certain distance from the second vibrating member 200-2. The third partition member 630 may form a second air gap (AG2) surrounding the second vibrating member 200-2 between the display panel 100 and the support member 300. For example, the third partition member 630 may be disposed between the second region (A2) of the plate member 150, which corresponds to the second region (A2) of the display panel 100, and the support member 300. For example, the third partition member 630 may define or limit the vibration region (or vibration area) of the second region (A2) of the display panel 100 caused by the second vibrating member 200-2.

[0166] The first air gap (AG1) and the second air gap (AG2) may be a sound separating space, a sound blocking space, or a sound interference preventing space, and the embodiments of this specification are not limited thereto.

[0167] The second and third partition members 620 and 630 can separate a first sound generated by the first vibrating member 200-1 from a second sound generated by the second vibrating member 200-2. For example, the second and third partition members 620 and 630 can block vibrations generated in a first region (A1) of the display panel 100 by the first vibrating member 200-1 from being transmitted to a second region (A2) of the display panel 100, or can block vibrations generated in the second region (A2) of the display panel 100 by the second vibrating member 200-2 from being transmitted to the first region (A1) of the display panel 100. Thus, the second and third partition members 620 and 630 can attenuate or absorb vibrations of the display panel 100, thereby blocking the transmission of sound in the first region (A1) to the second region (A2) or the transmission of sound in the second region (A2) to the first region (A1). Therefore, the second and third partition members 620, 630 can further improve the sound output characteristics of the display device by separating left and right sounds, and as a result, the display device according to the embodiments of the present specification can output stereo sound, including two-channel sound, or two-channel sound toward the front of the display panel 100 by separating left and right sounds using the second and third partition members 620, 630.

[0168] According to an embodiment of the present specification, the partition 600, the partition member 610, and the second and third partition members 620 and 630 may each be made of an elastic material that can be compressed to a certain extent, but the embodiment of the present specification is not limited thereto. In one embodiment of the present specification, the partition 600, the partition member 610, and the second and third partition members 620 and 630 may each be made of a polyurethane or polyolefin material, but the embodiment of the present specification is not limited thereto. In another embodiment of the present specification, the partition 600, the partition member 610, and the second and third partition members 620 and 630 may each be made of a single-sided tape, a single-sided foam tape, a double-sided tape, or a double-sided foam tape, etc.

[0169] According to other embodiments of the present specification, it is possible to configure only one of the partition member 610, the second and third partition members 620, 630. In this case as well, by disposing one of the partition member 610, the second and third partition members 620, 630 between the first vibrating member 200-1 and the second vibrating member 200-2, it is possible to separate left and right sounds.

[0170] Therefore, the left and right sounds are separated by one or more of the partition member 610, the second and third partition members 620, 630, thereby further improving the sound output characteristics of the display device, and the separation of the left and right sounds allows stereo sound, including two-channel sound, or two-channel sound to be output toward the front of the display panel 100.

[0171] 1 to 6, the display device according to the other embodiments of the present specification can output sound in the front direction (FD) of the display panel 100, and the thickness of the display device can be reduced or made slimmer. In addition, the display device according to the other embodiments of the present specification can output stereo sound including two-channel sound or two-channel sound in the front direction of the display panel 100 through left and right divided vibration of the display panel 100 due to vibration of the first and second vibrating members 200-1 and 200-2.

[0172] 9A to 9D are diagrams showing a display device according to another embodiment of the present specification. Figures 9A to 9D show a modification of the vibration layer of the vibration member described with reference to Figures 7 and 8. Therefore, in the following description, the modified configuration will be described in detail, and the remaining configuration will be given the same reference numerals as in Figures 7 and 8, and redundant description thereof will be omitted or briefly described.

[0173] Referring to FIG. 9A, in a display device according to another embodiment of the present specification, the vibrating member 200 may include a first vibrating member 200-1 configured in a first region (A1) of the display panel 100 and a second vibrating member 200-2 configured in a second region (A2) of the display panel 100.

[0174] In the first vibrating member 200-1, the vibrating layer 210 may be configured to have a size (or area) that is larger than half of the first region (A1) of the display panel 100 but smaller than the first region (A1) of the display panel 100. For example, the first vibrating member 200-1 may be configured to have a square shape within the first region (A1) of the display panel 100, with a size (or area) that is larger than half of the first region (A1) but smaller than the entire size of the first region (A1), thereby improving mid- and low-frequency sounds generated by vibration of the first region (A1) of the display panel 100. For example, the vibrating layer 210 of the first vibrating member 200-1 may be formed or applied in a square shape on the second surface of the plate member 150 corresponding to the first region (A1) of the display panel 100 and then molded. The second electrode 230 may be configured to have the same shape and size as the vibrating layer 210. The cover member 270 may be configured to cover the vibration layer 210 and the second electrode 230 .

[0175] In the second vibrating member 200-2, the vibrating layer 210 may be configured to have a size (or area) that is larger than half of the second region (A2) of the display panel 100 but smaller than the second region (A2) of the display panel 100. For example, the second vibrating member 200-2 may be configured to have a square shape within the second region (A2) of the display panel 100, with a size (or area) that is larger than half of the second region (A2) but smaller than the entire size of the second region (A2), thereby improving the mid- and low-frequency sound generated by vibration of the second region (A2) of the display panel 100. For example, the vibrating layer 210 of the second vibrating member 200-2 may be formed or applied in a square shape on the second surface of the plate member 150 corresponding to the second region (A2) of the display panel 100 and then molded. The second electrode 230 may be configured to have the same shape and size as the vibrating layer 210. The cover member 270 may be configured to cover the vibration layer 210 and the second electrode 230 .

[0176] The first vibrating member 200-1 and the second vibrating member 200-2 may be configured symmetrically with respect to the midpoint between the first area (A1) and the second area (A2) of the display panel 100 (or the partition member 610), but are not limited thereto and may be configured asymmetrically.

[0177] Referring to FIG. 9B, in a display device according to another embodiment of the present specification, the vibrating member 200 may include a first vibrating member 200-1 configured in a first region (A1) of the display panel 100 and a second vibrating member 200-2 configured in a second region (A2) of the display panel 100.

[0178] In the first vibrating member 200-1, the vibrating layer 210 may be configured to have a rectangular shape with a size (or area) equal to or less than half the size of the first region (A1) of the display panel 100. However, embodiments of the present specification are not limited thereto. The vibrating layer 210 may be configured to have a rectangular shape with a size (or area) greater than half the size of the first region (A1) but smaller than the entire size of the first region (A1). This may improve mid- and low-frequency sounds generated by vibration of the first region (A1) of the display panel 100. For example, the vibrating layer 210 of the first vibrating member 200-1 may be formed or applied in a rectangular shape on the second surface of the plate member 150 corresponding to the first region (A1) of the display panel 100 and then molded. The second electrode 230 may be configured to have the same shape and size as the vibrating layer 210. The cover member 270 may be configured to cover the vibrating layer 210 and the second electrode 230.

[0179] In the second vibrating member 200-2, the vibrating layer 210 may be configured to have a rectangular shape with a size (or area) equal to or less than half the size of the second region (A2) of the display panel 100. However, embodiments of the present specification are not limited thereto. The vibrating layer 210 may be configured to have a rectangular shape with a size (or area) greater than half the size of the second region (A2) but less than the entire size of the second region (A2). This may improve mid- and low-frequency sounds generated by vibration of the second region (A2) of the display panel 100. For example, the vibrating layer 210 of the second vibrating member 200-2 may be formed or coated and then molded into a rectangular shape on the second surface of the plate member 150 corresponding to the second region (A2) of the display panel 100. The second electrode 230 may be configured to have the same shape and size as the vibrating layer 210. The cover member 270 may be configured to cover the vibrating layer 210 and the second electrode 230.

[0180] The vibration layer 210 of each of the first vibration member 200-1 and the second vibration member 200-2 may have a rectangular shape including a long side parallel to a first direction (X) (e.g., the horizontal length direction of the display panel 100) and a short side parallel to a second direction (Y) (e.g., the vertical length direction of the display panel 100) that intersects the first direction (X).

[0181] The first vibrating member 200-1 and the second vibrating member 200-2 may be configured symmetrically with respect to the midpoint between the first area (A1) and the second area (A2) of the display panel 100 (or the partition member 610), but are not limited thereto and may be configured asymmetrically.

[0182] Referring to FIG. 9C, in a display device according to another embodiment of the present specification, the vibrating member 200 may include a first vibrating member 200-1 configured in a first region (A1) of the display panel 100 and a second vibrating member 200-2 configured in a second region (A2) of the display panel 100.

[0183] In the first vibrating member 200-1, the vibrating layer 210 may be configured to have a circular shape with a size (or area) equal to or less than half the size of the first region (A1) of the display panel 100. However, embodiments of the present specification are not limited thereto. The vibrating layer 210 may be configured to have a circular shape with a size (or area) greater than half the size of the first region (A1) but less than the entire size of the first region (A1). This allows the vibrating layer 210 to form a circular vibration source (or vibrator), thereby improving vibration characteristics or sound output characteristics and improving mid-to-low frequency sounds generated by vibration of the first region (A1) of the display panel 100. For example, the vibrating layer 210 of the first vibrating member 200-1 may be formed or coated in a circular shape on the second surface of the plate member 150 corresponding to the first region (A1) of the display panel 100 and then molded. The second electrode 230 may be configured to have the same shape and size as the vibrating layer 210. The cover member 270 may be configured to cover the vibration layer 210 and the second electrode 230 .

[0184] In the second vibrating member 200-2, the vibrating layer 210 may be configured to have a circular shape with a size (or area) equal to or less than half the size of the second region (A2) of the display panel 100. However, embodiments of the present specification are not limited thereto. The vibrating layer 210 may be configured to have a circular shape with a size (or area) greater than half the size of the second region (A2) but less than the entire size of the second region (A2). This allows the vibrating layer 210 to form a circular vibration source (or vibrator), thereby improving vibration characteristics or sound output characteristics and improving mid- and low-frequency sounds generated by vibration of the second region (A2) of the display panel 100. For example, the vibrating layer 210 of the second vibrating member 200-2 may be formed or coated in a circular shape on the second surface of the plate member 150 corresponding to the second region (A2) of the display panel 100 and then molded. The second electrode 230 may be configured to have the same shape and size as the vibrating layer 210. The cover member 270 may be configured to cover the vibration layer 210 and the second electrode 230 .

[0185] The first vibrating member 200-1 and the second vibrating member 200-2 may be configured symmetrically with respect to the midpoint between the first area (A1) and the second area (A2) of the display panel 100 (or the partition member 610), but are not limited to this and may also be configured asymmetrically.

[0186] Referring to FIG. 9D, in a display device according to another embodiment of the present specification, the vibrating member 200 may further include a third vibrating member 200-3 configured in the first region (A1) of the display panel 100 and a fourth vibrating member 200-4 configured in the second region (A2) of the display panel 100.

[0187] The first vibrating member 200-1 and the second vibrating member 200-2 are the same as the first vibrating member 200-1 and the second vibrating member 200-2 described with reference to FIG. 9C, and therefore a duplicated description thereof will be omitted.

[0188] The third vibrating member 200-3 may be arranged at an edge portion of the first region (A1) of the display panel 100. For example, the third vibrating member 200-3 may be arranged parallel to the first vibrating member 200-1 or diagonally opposite each other within the first region (A1) of the display panel 100. For example, the third vibrating member 200-3 may be configured to be spaced apart from the first vibrating member 200-1 along any one of the first direction (X), the second direction (Y), and a diagonal direction between the first direction (X) and the second direction (Y). For example, the third vibrating member 200-3 may be arranged at a corner portion on one side of the first region (A1) of the display panel 100. The third vibrating member 200-3 may be configured to have a smaller size (or area) than the first vibrating member 200-1, but the embodiments of the present specification are not limited thereto. The third vibrating member 200-3 vibrates the edge portion of the first area (A1) of the display panel 100, thereby improving the high-frequency sound generated by the vibration of the first area (A1) of the display panel 100.

[0189] The vibrating layer 210 of the third vibrating member 200-3 may have the same shape as or a different shape from the vibrating layer 210 of the first vibrating member 200-1. For example, the vibrating layer 210 of the third vibrating member 200-3 may have a square or rectangular shape, different from the vibrating layer 210 of the first vibrating member 200-1, but the embodiments of the present specification are not limited thereto. The vibrating layer 210 of the third vibrating member 200-3 may have the same circular shape as the vibrating layer 210 of the first vibrating member 200-1. For example, the vibrating layer 210 of the third vibrating member 200-3 may be formed or applied in a square shape (or a rectangular shape or a circular shape) on the second surface of the plate member 150 corresponding to the first region (A1) of the display panel 100 and then molded. The second electrode 230 may be configured to have the same shape and size as the vibrating layer 210. The cover member 270 may be configured to cover the vibrating layer 210 and the second electrode 230.

[0190] The fourth vibrating member 200-4 may be arranged at an edge portion of the second region (A2) of the display panel 100. For example, the fourth vibrating member 200-4 may be arranged parallel to or diagonally opposite the second vibrating member 200-2 within the second region (A2) of the display panel 100. For example, the fourth vibrating member 200-4 may be configured to be spaced apart from the second vibrating member 200-2 along any one of the first direction (X), the second direction (Y), and a diagonal direction between the first direction (X) and the second direction (Y). For example, the fourth vibrating member 200-4 may be arranged at a corner portion on one side of the second region (A2) of the display panel 100. The fourth vibrating member 200-4 may be configured to have a smaller size (or area) than the second vibrating member 200-2, although examples of the present specification are not limited thereto. The fourth vibrating member 200-4 vibrates the edge portion of the second area (A2) of the display panel 100, thereby improving the high-frequency range sound generated by the vibration of the second area (A2) of the display panel 100.

[0191] The vibrating layer 210 of the fourth vibrating member 200-4 may have the same shape as or a different shape from the vibrating layer 210 of the second vibrating member 200-2. For example, the vibrating layer 210 of the fourth vibrating member 200-4 may have a square or rectangular shape, different from the vibrating layer 210 of the second vibrating member 200-2, but the embodiments of the present specification are not limited thereto. The vibrating layer 210 of the fourth vibrating member 200-4 may have the same circular shape as the vibrating layer 210 of the second vibrating member 200-2. For example, the vibrating layer 210 of the fourth vibrating member 200-4 may be formed or coated in a square shape (or a rectangular shape or a circular shape) on the second surface of the plate member 150 corresponding to the second region (A2) of the display panel 100 and then molded. The second electrode 230 may be configured to have the same shape and size as the vibrating layer 210. The cover member 270 may be configured to cover the vibrating layer 210 and the second electrode 230.

[0192] The first vibrating member 200-1 and the second vibrating member 200-2 may be configured symmetrically with respect to the midpoint between the first area (A1) and the second area (A2) of the display panel 100 (or the partition member 610), but are not limited to this and may be configured asymmetrically. The third vibrating member 200-3 and the fourth vibrating member 200-4 may be configured symmetrically with respect to the midpoint between the first area (A1) and the second area (A2) of the display panel 100 (or the partition member 610), but are not limited to this and may be configured asymmetrically.

[0193] Figure 10 is a diagram showing a display device according to another embodiment of the present specification. Figure 10 shows a modification of the vibration layer of the vibration member described with reference to Figure 9A according to another embodiment of the present specification. Therefore, in the following description, the modified configuration will be described in detail, and the remaining configuration will be given the same reference numerals as in Figures 7 to 9A, and redundant description thereof will be omitted or will be briefly described.

[0194] Referring to FIG. 10, in a display device according to another embodiment of the present specification, the vibrating member 200 may include a first vibrating member 200-1 configured in a first region (A1) of the display panel 100 and a second vibrating member 200-2 configured in a second region (A2) of the display panel 100.

[0195] Each of the first vibrating member 200-1 and the second vibrating member 200-2 can include a plurality of vibrating layers (or one or more vibrating layers) 210 and a plurality of second electrodes (or one or more second electrodes) 230. Each of the first vibrating member 200-1 and the second vibrating member 200-2 can further include a cover member 270. Each of the first vibrating member 200-1 and the second vibrating member 200-2 can use the plate member 150 of the display panel 100 as a first electrode.

[0196] In each of the first vibrating member 200-1 and the second vibrating member 200-2, the plurality of vibrating layers 210 may be arranged on the second surface of the plate member 150 of the display panel 100 at regular intervals along the first direction (X) and the second direction (Y). For example, the plurality of vibrating layers 210 may be arranged in a lattice pattern at regular intervals along the first direction (X) and the second direction (Y). For example, the plurality of vibrating layers 210 may be arranged in an N×M (N and M are natural numbers equal to or greater than 2, and may be the same or different) lattice pattern at regular intervals along the first direction (X) and the second direction (Y).

[0197] Each of the plurality of vibration layers 210 may include a non-rectangular shape including one or more of three or more polygonal shapes, one or more straight lines and one or more curves with curvature, a circular shape, or an elliptical shape, but examples of the present specification are not limited thereto. For example, one or more of the plurality of vibration layers 210 may have different shapes. As an example of the present specification, each of the plurality of vibration layers 210 may have a square shape. As another example of the present specification, some of the plurality of vibration layers 210 may have a square shape and the rest may have a circular shape. As another example of the present specification, the plurality of vibration layers 210 may be divided into first to third groups. The vibration layers 210 included in the first group may have a square shape, the vibration layers 210 included in the second group may have a rectangular shape, and the vibration layers 210 included in the third group may have a circular shape. For example, if the first and second regions (A1, A2) of the display panel 100 each include a central region, a middle region, and an edge region, the vibration layer 210 included in the first group may be configured in the central region, the vibration layer 210 included in the second group may be configured in the middle region, and the vibration layer 210 included in the third group may be configured in the edge region, but the examples of the present specification are not limited thereto. For example, the shapes of the vibration layers 210 configured in each of the central region, middle region, and edge region may be changed depending on the acoustic characteristics and / or sound pressure characteristics of the display device.

[0198] Each of the plurality of second electrodes 230 may be configured to have the same shape and size as a corresponding vibration layer 210 among the plurality of vibration layers 210. The cover member 270 may be configured to cover the plurality of vibration layers 210 and the plurality of second electrodes 230 in common.

[0199] The signal cable 500 may include one or more first contact lines 511 and a plurality of second contact lines 513 .

[0200] The one or more first contact lines 511 may be configured to be electrically coupled to the plate member 150. For example, the one or more first contact lines 511 may be electrically coupled to a second surface of the plate member 150 exposed in the first region (A1) of the display panel 100.

[0201] The signal cable 500 may include a plurality of first contact lines 511. For example, the signal cable 500 may include two first contact lines 511. The two first contact lines 511 may extend (or protrude) long from the wiring portion 510 along the second direction (Y) and be electrically coupled to the second surface of the plate member 150 in a region between two adjacent vibration layers 210 along the first direction (X), thereby allowing a more uniform first vibration drive signal to be applied to each of the plurality of vibration layers 210.

[0202] Each of the plurality of second contact lines 513 may be configured to be electrically coupled to each of the plurality of second electrodes 230. Each of the plurality of second contact lines 513 may be extended (or protruded) long from the wiring part 510 along the second direction (Y) and electrically coupled to a corresponding second electrode 230 among the plurality of second electrodes 230.

[0203] In each of the first vibrating member 200-1 and the second vibrating member 200-2, each of the multiple vibrating layers 210 can vibrate identically or independently (or individually) by the same or different second vibration drive signals. For example, one or more of the second vibration drive signals applied to each of the multiple vibrating layers 210 can be different. This allows each of the first vibrating member 200-1 and the second vibrating member 200-2 to generate sound for two or more channels. For example, when the second vibration drive signals applied to each of the multiple vibrating layers 210 are all different, each of the first vibrating member 200-1 and the second vibrating member 200-2 can generate sound for N×M channels (N and M are N rows and M columns, and are natural numbers equal to or greater than two and may be the same or different).

[0204] According to one embodiment of the present specification, among the plurality of vibrating layers 210 arranged in a 3x3 pattern, the 1x1 to 1x3 vibrating layers 210 may form upper channels, the 2x1 to 2x3 vibrating layers 210 may form middle channels, and the 3x1 to 3x3 vibrating layers 210 may form lower channels. As a result, each of the first vibrating member 200-1 and the second vibrating member 200-2 can generate three-channel or horizontal three-channel sounds.

[0205] According to one embodiment of the present specification, in the plurality of vibration layers 210 arranged in a 3x3 configuration, the first x1, second x1, and third x1 vibration layers 210 may form a left channel, the first x2, second x2, and third x2 vibration layers 210 may form a middle channel, and the first x3, second x3, and third x3 vibration layers 210 may form a right channel. This allows each of the first vibrating member 200-1 and the second vibrating member 200-2 to generate three-channel or vertical three-channel sound.

[0206] The first vibrating member 200-1 and the second vibrating member 200-2 may be configured symmetrically with respect to the midpoint between the first area (A1) and the second area (A2) of the display panel 100 (or the partition member 610), but are not limited thereto and may also be configured asymmetrically.

[0207] FIG. 11 is a diagram showing a display device according to another embodiment of the present specification. FIG. 12 is an enlarged view of a portion "B1" shown in FIG. 11 according to another embodiment of the present specification. FIGS. 11 and 12 show a modification of the vibration layer of the vibration member described with reference to FIGS. 7 to 9A and 10. Therefore, in the following description, the modified configuration will be described in detail, and the remaining configuration will be given the same reference numerals as FIGS. 7 to 9A and 10, and redundant description thereof will be omitted or will be briefly described.

[0208] Referring to Figures 11 and 12, in a display device according to another embodiment of the present specification, the vibrating member 200 may include a first vibrating member 200-1 configured in a first region (A1) of the display panel 100 and a second vibrating member 200-2 configured in a second region (A2) of the display panel 100.

[0209] Each of the first vibrating member 200-1 and the second vibrating member 200-2 can include a plurality of vibrating layers (or one or more vibrating layers) 210 and a plurality of second electrodes (or one or more second electrodes) 230. Each of the first vibrating member 200-1 and the second vibrating member 200-2 can further include a cover member 270. Each of the first vibrating member 200-1 and the second vibrating member 200-2 can use the plate member 150 of the display panel 100 as a first electrode.

[0210] In each of the first vibrating member 200-1 and the second vibrating member 200-2, the plurality of vibrating layers 210 are substantially the same as the plurality of vibrating layers 210 described with reference to Fig. 10 except for their size (or area), and therefore, redundant description thereof will be omitted or simplified. The plurality of vibrating layers 210 may be configured in an N x M (N and M are the same or different natural numbers of 2 or greater) lattice pattern having regular intervals along the first direction (X) and the second direction (Y). The description of the plurality of vibrating layers 210 described with reference to Fig. 10 may be included in the description of the vibrating layer 210 shown in Figs. 11 and 12.

[0211] Each of the plurality of vibration layers 210 may be configured to have a size (or area) that will not be damaged or broken even if it is bent or curved, so that the display panel 100 has a certain radius of curvature. For example, each of the plurality of vibration layers 210 may be a micro-vibration layer.

[0212] Each of the plurality of second electrodes 230 can be configured to have the same shape and size as a corresponding vibration layer 210 among the plurality of vibration layers 210. The cover member 270 can be configured to cover the plurality of vibration layers 210 and the plurality of second electrodes 230 in common.

[0213] The signal cable 500 may include one or more first contact lines 511 electrically coupled to the plate member 150 and a plurality of second contact lines 513 electrically coupled to each of the plurality of second electrodes 230, which is substantially the same as the signal cable 500 described with reference to FIG. 10, and therefore, a duplicate description thereof will be omitted.

[0214] In each of the first vibrating member 200-1 and the second vibrating member 200-2, each of the multiple vibrating layers 210 can vibrate identically or independently (or individually) by the same or different second vibration drive signals. For example, one or more of the second vibration drive signals applied to each of the multiple vibrating layers 210 can be different. This allows each of the first vibrating member 200-1 and the second vibrating member 200-2 to generate sound of two or more channels. For example, when the second vibration drive signals applied to each of the multiple vibrating layers 210 are all different, each of the first vibrating member 200-1 and the second vibrating member 200-2 can generate sound of N×M channels.

[0215] The first vibrating member 200-1 and the second vibrating member 200-2 may be configured symmetrically with respect to the midpoint between the first area (A1) and the second area (A2) of the display panel 100 (or the partition member 610), but are not limited thereto and may be configured asymmetrically.

[0216] Fig. 13 is a diagram showing the rear surface of a display panel and a vibrating member in a display device according to another embodiment of the present specification. Fig. 14 is a cross-sectional view taken along line IV-IV' in Fig. 13 according to another embodiment of the present specification. Figs. 13 and 14 show modifications of the vibrating member described with reference to Figs. 1 to 6. Therefore, in the following description, only the modified configuration will be described in detail, and the remaining configuration will be given the same reference numerals as Figs. 1 to 6, and redundant descriptions thereof will be omitted or briefly described.

[0217] 13 and 14, a vibration member 200 of a display device according to another embodiment of the present disclosure may include a vibration layer 210, an insulating layer 220, a second electrode 230, and a protection layer 240.

[0218] The vibrating member 200 can use the plate member 150 of the display panel 100 as a first electrode. For example, the plate member 150 of the display panel 100 can serve as the first electrode of the vibrating member 200.

[0219] The vibration layer 210 may be configured on the plate member 150 of the display panel 100, and is substantially the same as the vibration layer 210 described with reference to FIGS. 1 to 6, so a duplicated description thereof will be omitted.

[0220] The insulating layer 220 may be disposed on the second surface 150a of the plate member 150 around the periphery of the vibration layer 210. For example, the insulating layer 220 may be disposed on the second surface 150a of the plate member 150 so as to surround each side of the vibration layer 210. For example, the insulating layer 220 may be disposed on part or all of the remaining portion of the second surface 150a of the plate member 150 excluding the region where the vibration layer 210 is disposed.

[0221] The insulating layer 220 may be formed to have a thickness thinner than that of the vibration layer 210. For example, the top surface of the insulating layer 220 may be disposed below the top surface of the vibration layer 210, or may be disposed closer to the plate member 150 than the top surface of the vibration layer 210. For example, if the insulating layer 220 has the same thickness as the vibration layer 210 or a thickness thicker than that of the vibration layer 210, the top surface (or second surface) of the vibration layer 210 may be contaminated during the formation process of the insulating layer 220. To prevent this, the insulating layer 220 may be formed to have a thickness thinner than that of the vibration layer 210. For example, the insulating layer 220 may be made of an organic or inorganic material. For example, the insulating layer 220 may include an organic material such as an acrylic resin, an epoxy resin, a phenolic resin, a polyamide resin, or a polyimide resin, or the insulating layer 220 may include an inorganic material such as silicon oxide (SiOx) or silicon nitride (SiNx).

[0222] The insulating layer 220 may include an exposure hole 221 (see FIG. 16 ) for exposing a portion of the plate member 150. The exposure hole 221 may be formed by removing a portion of the insulating layer 220 disposed on a portion of the plate member 150. According to one embodiment of the present specification, the exposure hole 221 may be formed by removing a portion of the insulating layer 220 disposed around the vibration layer 210.

[0223] The second electrode 230 may be configured on or coupled to the second surface 210a of the vibration layer 210. The second electrode 230 may have the same size as the vibration layer 210 or may have a smaller size than the vibration layer 210.

[0224] The vibration member 200 or the second electrode 230 may further include an extension line (or one or more extension lines) 231 .

[0225] The extension line 231 may protrude or extend from one side of the second electrode 230 onto the insulating layer 220 adjacent to the exposure hole 221. The extension line 231 may be formed on the insulating layer 220 together with the second electrode 230 formed on the second surface 210a of the vibration layer 210. An end of the extension line 231 may be arranged parallel to the exposure hole 221. For example, the extension line 231 may be an extension electrode, a protruding line, an extension electrode, or a protruding electrode, but the embodiments of the present specification are not limited thereto.

[0226] The protective layer 240 may be configured to protect the insulating layer 220 and the second electrode 230. For example, the protective layer 240 may be configured to protect the vibration member 200. For example, the protective layer 240 may be configured to cover the entire second surface 150a of the plate member 150 except for an edge portion on one side adjacent to the pad portion of the display panel 100. For example, the protective layer 240 may be made of an inorganic or organic material. For example, the protective layer 240 may be made of the same material as the insulating layer 220. For example, the protective layer 240 may include an organic material such as acrylic resin, epoxy resin, phenolic resin, polyamide resin, or polyimide resin, or the protective layer 240 may include an inorganic material such as silicon oxide (SiOx) or silicon nitride (SiNx), but the embodiments of the present specification are not limited thereto.

[0227] The protective layer 240 may include a first hole 241 and a second hole 242. For example, the protective layer 240 may include the first hole 241 and the second hole 242 arranged parallel to each other.

[0228] The first hole 241 may be formed in the protective layer 240 to overlap the exposure hole 221 disposed in the insulating layer 220. The first hole 241 may be configured to expose a portion of the plate member 150 overlapping the exposure hole 221. For example, the first hole 241 may be formed to penetrate both the insulating layer 220 and the protective layer 240, overlapping a portion of the plate member 150, thereby exposing a portion of the plate member 150 to the outside of the protective layer 240. Alternatively, the exposure hole 221 formed in the insulating layer 220 may be omitted, or the process of forming the exposure hole 221 in the insulating layer 220 may be omitted. For example, the first hole 241 may be a first electrode exposure hole, a first electrode contact hole, a first signal line contact hole, or a first line contact hole, but the embodiments of the present specification are not limited thereto.

[0229] The second hole 242 may be formed in the protective layer 240 adjacent to the first hole 241. The second hole 242 may be configured to expose a portion of the extension line 231 of the second electrode 230. For example, the second hole 242 may be formed to penetrate the protective layer 240 overlapping a portion of the extension line 231 of the second electrode 230, thereby exposing the portion of the extension line 231 of the second electrode 230 to the outside of the protective layer 240. For example, the second hole 242 may be a second electrode exposure hole, a second electrode contact hole, a second signal line contact hole, or a second line contact hole, but the embodiments of the present specification are not limited thereto.

[0230] A portion of the protective layer 240 in which the first hole 241 and the second hole 242 are formed may be a pad portion of the vibrating member 200. The pad portion of the vibrating member 200 may be electrically coupled to the signal cable 500. For example, the pad portion of the vibrating member 200 may be disposed in a peripheral region of the vibrating member 200 that does not overlap with the vibrating layer 210. For example, the pad portion of the vibrating member 200 may be configured at a position on the rear surface of the display panel 100 that facilitates the coupling process with the signal cable 500.

[0231] The signal cable 500 may include a wiring portion 510 , a first contact line 511 , a second contact line 513 , and a terminal portion 530 .

[0232] The wiring unit 510 may be disposed on the rear surface of the display panel 100 and on the protective layer 240 of the vibrating member 200. The wiring unit 510 may include a base film, a wiring layer having first and second signal lines formed on the base film, and an insulating layer covering the wiring layer.

[0233] The first contact line 511 may be configured to be electrically connected to (or in contact with) the first electrode (or plate member) 150 of the vibrating member 200. For example, the first contact line 511 may be a part of a first signal line exposed at an edge portion on one side of the wiring part 510. The first contact line 511 may be electrically connected to (or in contact with) the first electrode (or plate member) 150 of the vibrating member 200 through a first hole 241. For example, the first hole 241 of the protective layer 240 may be configured between a portion of the first electrode (or plate member) 150 and the first contact line 511. For example, the first contact line 511 may be electrically connected to (or in contact with) the first electrode (or plate member) 150 of the vibrating member 200 through a conductive material filled in the first hole 241 of the protective layer 240. For example, the first contact line 511 may be electrically connected (or contacted) with the first electrode (or plate member) 150 of the vibration member 200 via an anisotropic conductive film including conductive particles 550 (see FIG. 16) filled in the first hole 241.

[0234] The second contact line 513 may be configured to be electrically connected to (or in contact with) the second electrode 230 of the vibrating member 200. For example, the second contact line 513 may be configured to be electrically connected to (or in contact with) the extension line 231 of the second electrode 230. For example, the second contact line 513 may be a part of a second signal line exposed at an edge portion of one side of the wiring part 510. The second contact line 513 may be electrically connected to (or in contact with) the extension line 231 of the second electrode 230 through a second hole 242. For example, the second hole 242 of the protective layer 240 may be configured between a part of the extension line 231 and the second contact line 513. For example, the second contact line 513 may be electrically connected to (or in contact with) the extension line 231 of the second electrode 230 through a conductive material filled in the second hole 242 of the protective layer 240. For example, the second contact line 513 may be electrically connected (or in contact) with the extension line 231 of the second electrode 230 of the vibration member 200 via an anisotropic conductive film including conductive particles 550 filled in the second holes 242.

[0235] The terminal portion 530 may be formed on the other edge portion of the wiring portion 510 .

[0236] The signal cable 500 is electrically coupled to the first electrode (or plate member) 150 and the second electrode 230, thereby enabling the first and second vibration drive signals supplied from the vibration drive circuit (or acoustic processing circuit) via the terminal portion 530 to be applied or transmitted to the first electrode (or plate member) 150 and the second electrode 230 of the vibration member 200.

[0237] The vibrating member 200 described with reference to Figures 7 to 12 can be similarly applied to the vibrating member 200 described with reference to Figures 13 and 14. For example, the vibrating member 200 described with reference to Figures 13 and 14 can be configured in the same manner as the vibrating member 200 described with reference to Figures 7 to 12, and therefore, a duplicated description thereof will be omitted.

[0238] 1 to 6, the display device according to the other embodiment of the present specification can output sound in the front direction (FD) of the display panel 100, and the thickness of the display device can be reduced or made slimmer. Also, in the display device according to the other embodiment of the present specification, the pad portion of the vibrating member 200 is disposed in the peripheral region of the vibrating member 200 that does not overlap with the vibrating layer 210, which makes it easier to connect the pad portion of the vibrating member 200 to the signal cable 500.

[0239] FIG. 15 is a view showing the rear surface of a display panel and a vibrating member in a display device according to another embodiment of the present specification. FIG. 16 is a cross-sectional view taken along line V-V' in FIG. 15 according to another embodiment of the present specification. FIGS. 15 and 16 show a display device or a vibrating member described with reference to FIGS. 13 and 14, to which a cover member is further added. Therefore, in the following description, the added components will be described in detail, and the remaining components will be given the same reference numerals as in FIGS. 13 and 14, and redundant descriptions thereof will be omitted or briefly described.

[0240] 15 and 16, a display or vibration member 200 according to another embodiment of the present disclosure may further include a cover member 290. In the example shown in FIG.

[0241] The cover member 290 may be configured to cover the protective layer 240 of the vibrating member 200 and a portion of the signal cable 500. The cover member 290 may be configured to surround or cover the remaining portion of the signal cable 500 excluding the terminal portion 530 and the protective layer 240 of the vibrating member 200. For example, the cover member 270 may be a cover film, cover layer, protective member, or protective layer, although the embodiments of the present specification are not limited thereto. For example, the cover member 290 may be a polyimide (PI) film, a polyethylene terephthalate (PET) film, or a polyethylene naphthalate (PEN) film, although the embodiments of the present specification are not limited thereto.

[0242] The cover member 290 may be connected or bonded to the protective layer 240 of the vibrating member 200 and a portion of the signal cable 500 via the adhesive layer 280. For example, the cover member 290 may be connected or bonded to the protective layer 240 of the vibrating member 200 and a portion of the signal cable 500 by a film lamination process using the adhesive layer 280 as an intermediary. In this way, the portion of the signal cable 500 may be embedded or built-in between the protective layer 240 of the vibrating member 200 and the adhesive layer 280 (or the cover member 290), thereby being integrated into or fixed to the vibrating member 200.

[0243] The adhesive layer 280 may include an electrically insulating material that is compressible and resilient while having adhesive properties. For example, the adhesive layer 280 may include an epoxy-based resin, an acrylic-based resin, a silicone-based resin, or a urethane-based resin, but the embodiments of the present specification are not limited thereto.

[0244] The vibrating member 200 described with reference to Figures 7 to 12 can be applied to the vibrating member 200 described with reference to Figures 15 and 16. For example, the vibrating member 200 described with reference to Figures 15 and 16 can be configured to include the first vibrating member 200-1 and the second vibrating member 200-2 of the vibrating member 200 described with reference to Figures 7 to 12, and therefore, a redundant description thereof will be omitted.

[0245] 13 and 14, a display device according to another embodiment of the present specification can output sound in the front direction (FD) of the display panel 100, and can be reduced in thickness or slimmed down, facilitating the process of connecting the pad portion of the vibrating member 200 and the signal cable 500. In addition, a display device according to another embodiment of the present specification can protect the vibrating member 200 from external impacts by including a protective layer 240 of the vibrating member 200 and a cover member 290 that covers a portion of the signal cable 500, and can reduce poor contact between the pad portion of the vibrating member 200 and the signal cable 500 due to movement or bending of the signal cable 500.

[0246] Figure 17 is a view showing the rear surface of a display panel and a vibrating member in a display device according to another embodiment of the present specification. Figure 18 is a cross-sectional view taken along line VI-VI' in Figure 17 according to another embodiment of the present specification. Figures 17 and 18 show modifications to the plate member described with reference to Figures 7 and 8. Therefore, in the following description, only the modified configuration will be described in detail, and the remaining configuration will be given the same reference numerals as Figures 7 and 8, and redundant descriptions thereof will be omitted or briefly described.

[0247] 17 and 18, in a display device according to another embodiment of the present disclosure, a plate member 150 of a display panel 100 may include an inner plate 151 and a plurality of outer plates 152. In the embodiment shown in FIG.

[0248] The inner plate 151 is substantially the same as the plate member 150 described with reference to FIGS. 1 to 3, and therefore, a duplicated description thereof will be omitted or simplified.

[0249] The internal plate 151 may be configured to cover the display unit 130. The internal plate 151 may be attached to the display unit 130 via an adhesive member. The adhesive member may be configured on the base member 110 to surround the display unit 130. A first surface 151a of the internal plate 151 may be bonded (or attached) to the adhesive member or directly bonded (or attached) to the adhesive member. The internal plate 151 may additionally or effectively dissipate heat generated in the display panel 100, thereby reducing image quality degradation due to image retention that is partially caused by the heat generated in the display panel 100. The internal plate 151 may protect the display unit 130 or the display panel 100 from external impact and prevent external moisture or humidity from penetrating into the light-emitting element layer. The internal plate 151 may compensate for the rigidity of the display panel 100. For example, the internal plate 151 may be an internal conductive plate, an internal heat dissipation member, an internal heat dissipation plate, an internal heat dissipation substrate, a sealing substrate, a sealing plate, a rigid plate, a second substrate, a rear substrate, a rear member, a rear plate, an internal substrate, or an internal plate, but examples of the present specification are not limited thereto.

[0250] The multiple external plates 152 may be configured to be connected or coupled to the internal plate 151. The multiple external plates 152 may be configured to be spaced apart from each other or electrically isolated from each other on the back surface (or second surface) 151b of the internal plate 151. The multiple external plates 152 may be configured to further dissipate heat from the internal plate 151. For example, the multiple external plates 152 may be configured to have a relatively thinner thickness than the internal plate 151.

[0251] According to one embodiment of the present disclosure, the outer plates 152 may be made of one or more materials selected from the group consisting of an iron-nickel alloy, stainless steel, aluminum (Al), magnesium (Mg), a magnesium (Mg) alloy, a magnesium-lithium (Mg-Li) alloy, and an aluminum (Al) alloy, but the present disclosure is not limited thereto. For example, the outer plates 152 may be made of one or more materials selected from the group consisting of an iron-nickel alloy, stainless steel, aluminum (Al), magnesium (Mg), a magnesium (Mg) alloy, a magnesium-lithium (Mg-Li) alloy, and an aluminum (Al) alloy, but different from the inner plate 151. For example, the outer plates 152 may be made of aluminum (Al) or an aluminum (Al) alloy.

[0252] The plate member 150 or plurality of outer plates 152 according to one embodiment of the present disclosure may include a first outer plate 152a and a second outer plate 152b.

[0253] The first outer plate 152a may be connected or coupled to a first region of the inner plate 151 corresponding to a first region (A1) of the display panel 100. The second outer plate 152b may be connected or coupled to a second region of the inner plate 151 corresponding to a second region (A2) of the display panel 100.

[0254] Each of the first outer plate 152 a and the second outer plate 152 b can be coupled to the rear surface (or second surface) 151 b of the inner plate 151 via a coupling member 153 .

[0255] The coupling members 153 may be disposed between the first outer plate 152a, the second outer plate 152b, and the inner plate 151, respectively.

[0256] The coupling member 153 according to an embodiment of the present disclosure may include an adhesive material that has excellent adhesion or bonding strength between each of the first outer plate 152a and the second outer plate 152b and the inner plate 151. For example, the coupling member 153 may include an acrylic-based or urethane-based adhesive material, but the embodiment of the present disclosure is not limited thereto. For example, the coupling member 153 may include an acrylic-based adhesive material that has relatively excellent adhesion and high hardness properties so that vibrations of the vibrating member 200 are efficiently transmitted to the inner plate 151. For example, the coupling member 153 may include a double-sided foam adhesive pad with an acrylic-based adhesive layer or an acrylic-based adhesive resin cured layer. The adhesive layer of the coupling member 153 may further include additives such as a tackifier, a wax component, or an antioxidant.

[0257] The coupling member 153 according to other embodiments of the present specification may include a pressure sensitive adhesive (PSA), an optically cleared adhesive (OCA), or an optically cleared resin (OCR). For example, the coupling member 153 may further include a vibration transmission medium. For example, the vibration transmission medium may reduce loss of vibration transmitted to the inner plate 151. For example, the vibration transmission medium may include a piezoelectric material contained in or added to the coupling member 153.

[0258] The coupling member 153 according to other embodiments of the present specification may further include hollow portions provided between each of the first and second outer plates 152a and 152b and the inner plate 151. The hollow portions of the coupling member 153 may provide air gaps between each of the first and second outer plates 152a and 152b and the inner plate 151. The air gaps allow sound waves (or sound pressure) caused by the vibration of the vibrating member 200 to be concentrated on the inner plate 151 without being dispersed by the coupling member 153, thereby minimizing vibration loss caused by the coupling member 153.

[0259] The first outer plate 152a and the second outer plate 152b may be spaced apart from each other in an intermediate region between the first region (A1) and the second region (A2) of the display panel 100. The distance D1 between the first outer plate 152a and the second outer plate 152b may be 3 cm or more. For example, the distance D1 between the first outer plate 152a and the second outer plate 152b may be 3 cm or more so that the first outer plate 152a and the second outer plate 152b can vibrate individually (or independently). For example, if the distance D1 between the first outer plate 152a and the second outer plate 152b is less than 3 cm, interference between the vibrations of the first outer plate 152a and the second outer plate 152b generated by the vibration of the vibrating member 200 may result in a decrease in acoustic characteristics and / or sound pressure characteristics.

[0260] The vibrating member 200 may be configured to vibrate each of the multiple outer plates 152a, 152b. For example, the vibrating member 200 may be configured to use each of the multiple outer plates 152a, 152b as an electrode. For example, the vibrating member 200 may be configured to vibrate each of the first outer plate 152a and the second outer plate 152b individually (or independently). For example, the vibrating member 200 may be configured to use each of the first outer plate 152a and the second outer plate 152b as an electrode. For example, the vibrating member 200 may include a first vibrating member 200-1 configured on the back surface of the first outer plate 152a and a second vibrating member 200-2 configured on the back surface of the second outer plate 152b.

[0261] The first vibrating member 200-1 and the second vibrating member 200-2 are substantially the same as the first vibrating member 200-1 and the second vibrating member 200-2 described with reference to FIG. 7, except that they are configured on the back surfaces of the first outer plate 152a and the second outer plate 152b, respectively, and therefore, redundant explanations thereof will be omitted or simplified.

[0262] The first vibrating member 200-1 may include a vibrating layer 210 and a second electrode 230. The vibrating layer 210 of the first vibrating member 200-1 may be formed on the rear surface of the first outer plate 152a or may be applied and then molded. The second electrode 230 of the first vibrating member 200-1 may be configured to have the same shape and size as the vibrating layer 210. The first vibrating member 200-1 may further include a cover member 270 configured to cover the vibrating layer 210 and the second electrode 230. In one embodiment of the present specification, the vibrating layer 210 of the first vibrating member 200-1 vibrates in response to a first vibration drive signal applied to the first outer plate 152a and a second vibration drive signal applied to the second electrode 230, thereby vibrating the first outer plate 152a and a first region A1 of the display panel 100 and outputting a first sound. In another embodiment of the present specification, the vibration layer 210 of the first vibration member 200-1 can vibrate in response to a second vibration drive signal applied to the first outer plate 152a and a first vibration drive signal applied to the second electrode 230 via the signal cable 500, thereby vibrating the first outer plate 152a and the first area (A1) of the display panel 100 and outputting a first sound.

[0263] The second vibrating member 200-2 may include a vibrating layer 210 and a second electrode 230. The vibrating layer 210 of the second vibrating member 200-2 may be formed on the rear surface of the second outer plate 152b or may be molded after being applied thereto. The second electrode 230 of the second vibrating member 200-2 may be configured to have the same shape and size as the vibrating layer 210. The second vibrating member 200-2 may further include a cover member 270 configured to cover the vibrating layer 210 and the second electrode 230. In one embodiment of the present specification, the vibrating layer 210 of the second vibrating member 200-2 may vibrate in response to a first vibration drive signal applied to the second outer plate 152b and a second vibration drive signal applied to the second electrode 230, thereby vibrating the second outer plate 152b and a second area (A2) of the display panel 100 and outputting a second sound. In another embodiment of the present specification, the vibration layer 210 of the second vibration member 200-2 can vibrate in response to a second vibration drive signal applied to the second outer plate 152b and a first vibration drive signal applied to the second electrode 230 via the signal cable 500, thereby vibrating the second outer plate 152b and the second area (A2) of the display panel 100 and outputting a second sound.

[0264] The first vibrating member 200-1 and the second vibrating member 200-2 can be configured symmetrically with respect to the midpoint between the first area (A1) and the second area (A2) of the display panel 100, but this is not limited thereto and they may also be configured asymmetrically.

[0265] The vibrating member 200 described with reference to Figures 9A to 12 can be similarly applied to the vibrating member 200 described with reference to Figures 17 and 18. For example, the vibrating member 200 described with reference to Figures 17 and 18 can be configured in the same manner as the vibrating member 200 described with reference to Figures 9A to 12, and therefore, a duplicated description thereof will be omitted.

[0266] 1 to 6, a display device according to another embodiment of the present specification can output sound in a front direction (FD) of the display panel 100 and can be slimmed down or reduced in thickness. In addition, the display device according to another embodiment of the present specification includes an inner plate 151 and a plurality of outer plates 152 of a plate member 150, thereby more effectively dissipating heat generated in the display panel 100 and reducing degradation of image quality due to image retention caused partially by heat generated in the display panel 100. In addition, the display device according to another embodiment of the present specification can output two-channel stereo sound in a front direction of the display panel 100 through left and right divided vibration of the display panel 100 caused by vibration of first and second vibrating members 200-1 and 200-2 formed on a first outer plate 152a and a second outer plate 152b, respectively, which are separated from each other.

[0267] Figure 19 is a view showing the rear surface of a display panel and a vibrating member in a display device according to another embodiment of the present specification. Figure 20 is a cross-sectional view taken along line VII-VII' in Figure 19 according to another embodiment of the present specification. Figures 19 and 20 show the display device described with reference to Figures 17 and 18, to which a partition is further added. Therefore, in the following description, the partition and related components will be described in detail, and the remaining components will be given the same reference numerals as in Figures 7 and 8, and redundant descriptions thereof will be omitted or will be briefly described.

[0268] 19 and 20, a display device according to another embodiment of the present disclosure may further include a partition 600 that divides the display panel 100 into a first area (A1) and a second area (A2).

[0269] The display panel 100 may include regions (A1, A2) divided to correspond to each of the plurality of outer plates 152 of the plate member 150. For example, the display panel 100 may include regions (A1, A2) divided along the regions between the plurality of outer plates 152. For example, the display panel 100 may include a first region (A1) overlapping with the first outer plate 152a of the plate member 150 and a second region (A2) overlapping with the second outer plate 152b of the plate member 150.

[0270] The partition 600 may be an air gap or space through which sound is generated when the display panel 110 is vibrated by the first and second vibrating members 200-1 and 200-2. For example, the partition 600 may separate sounds or separate channels, thereby preventing or reducing degradation of acoustic characteristics due to acoustic interference. The partition 600 may be disposed between the display panel 100 and the support member 300. For example, the partition 600 may be disposed between the rear surface of the display panel 100 and the front surface of the support member 300. The partition 600 may be disposed on the support member 300 to reduce the effect of the partition 600 on the image quality of the display panel 100. The partition 600 may be referred to as a sound-blocking member, a sound-separating member, a space-separating member, an enclosure, a baffle, or the like, but the embodiments of the present specification are not limited to these terms.

[0271] The partition 600 according to embodiments herein may include a partition member (or first partition member) 610 disposed between the first and second vibrating members 200-1, 200-2.

[0272] The partition member 610 may be disposed between the first area (A1) and the second area (A2) of the display panel 100. The partition member 610 may be disposed between the support member 300 and the inner plate 151 of the plate member 150, which is located between the first area (A1) and the second area (A2) of the display panel 100. For example, the partition member 610 may be disposed between the support member 300 and the second surface 151b of the inner plate 151, which corresponds to an intermediate area between the first area (A1) and the second area (A2) of the display panel 100. The partition member 610 can separate a first sound generated by the first vibrating member 200-1 from a second sound generated by the second vibrating member 200-2. For example, the partition member 610 can block vibrations generated in the first region (A1) of the display panel 100 by the first vibrating member 200-1 from being transmitted to the second region (A2) of the display panel 100, or can block vibrations generated in the second region (A2) of the display panel 100 by the second vibrating member 200-2 from being transmitted to the first region (A1) of the display panel 100. Thus, the partition member 610 can attenuate or absorb the vibrations of the display panel 100 at the center of the display panel 100, thereby blocking sound in the first region (A1) from being transmitted to the second region (A2) or sound in the second region (A2) from being transmitted to the first region (A1). Therefore, the partition member 610 can further improve the sound output characteristics of the display device by separating left and right sounds, and as a result, the display device according to the embodiments of the present specification can output stereo sound including two-channel sound or two-channel sound toward the front of the display panel 100 by separating left and right sounds by the partition member 610.

[0273] A partition 600 according to embodiments herein may include a second partition member 620 surrounding the first vibrating member 200-1 and a third partition member 630 surrounding the second vibrating member 200-2.
