Description

[0001] This application is a divisional application of the original invention patent application No. 202011105614.8 (filed on October 15, 2020, invention title: display device).

[0002] Cross-references to related applications

[0003] This application claims the benefit and priority of Korean Patent Application No. 10-2019-0132514, filed on October 23, 2019, the entire contents of which are hereby incorporated by reference as fully set forth herein. Technical Field

[0005] Typically, display devices are incorporated into household appliances or electronic devices such as televisions (TVs), monitors, laptops, smartphones, tablets, electronic notebooks, electronic boards, wearable devices, smartwatches, portable information devices, navigation devices, and automotive control display devices, and are used as screens for displaying images.

[0006] Display devices may include a display panel for displaying images and a sound device for outputting sound associated with the images.

[0007] However, in display devices, sound quality can be degraded due to interference from reflections from walls and the floor, as sound from the audio output can propagate backward or downward. This can make it difficult to transmit accurate sound and reduce the viewer's immersive experience. Summary of the Invention

[0009] The inventors have recognized the problems of the display device described above and have conducted various experiments to ensure that when a user is viewing an image in front of the display panel, the direction of sound propagation is towards the front surface of the display panel. Therefore, sound quality can be improved. Thus, through various experiments, the inventors have invented a display device with a new structure that can generate sound that propagates to the forward area in front of the display panel, thereby improving sound quality.

[0010] One aspect of this disclosure is to provide a display device for providing improved sound quality and increasing the viewer's immersive experience.

[0099] The advantages and features of this disclosure and its implementation methods will be clarified by the following embodiments described with reference to the accompanying drawings. However, this disclosure may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Furthermore, this disclosure is limited only by the scope of the claims.

[0100] Throughout the accompanying drawings and detailed description, unless otherwise described, the same reference numerals should be understood to refer to the same elements, features, and structures. For clarity, illustration, and convenience, the relative dimensions and depictions of these elements may be enlarged. The described sequence of processing steps and / or operations is exemplary; however, the order of steps and / or operations is not limited to the order set forth herein and can be changed as is known in the art, except that the steps and / or operations must occur in a specific order. The same reference numerals denote the same elements throughout. The names of the various elements used in the following description are chosen solely for convenience of writing the specification and may therefore differ from the names used in the actual product.

[0101] The shapes, dimensions, ratios, angles, and quantities disclosed in the accompanying drawings to describe embodiments of this disclosure are merely examples, and therefore, this disclosure is not limited to the illustrated details. The same reference numerals refer to the same elements throughout. In the following description, detailed descriptions of relevant known art will be omitted where it is determined that such descriptions would unnecessarily obscure the essential points of this disclosure.

[0102] Where the terms “comprising,” “having,” and “including” are used as described in this specification, another component may be added unless “only” is used. Unless otherwise stated, singular terms may include plural forms.

[0103] When interpreting a component, it is interpreted as including a range of errors or tolerances, but such range of errors or tolerances is not explicitly described.

[0104] When describing positional relationships, for example, when the positional relationship between two components is described as "on," "above," "below," and "next to," one or more other components may be positioned between the two components unless more restrictive terms such as "just" or "directly" are used.

[0105] When describing temporal relationships, such as when describing temporal order as "after," "following," "next," and "before," discontinuous situations may be included unless more restrictive terms such as "exactly," "immediately after," or "directly" are used.

[0106] It should be understood that although the terms “first,” “second,” etc., may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, without departing from the scope of this disclosure, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.

[0107] In describing the elements of this disclosure, the terms “first,” “second,” “A,” “B,” “(a),” “(b),” etc., may be used. These terms are intended to identify the corresponding element from other elements, and the basis, order, or number of the corresponding elements shall not be limited by these terms. Unless otherwise specified, the expression “connected,” “joined,” or “adhered” to another element or layer means that the element or layer is not only directly connected or adhered to another element or layer, but also indirectly connected or adhered to another element or layer where one or more intermediate elements or layers are “set” between these elements or layers.

[0108] The term "at least one" should be understood as any and all combinations including one or more of the relevant listed items. For example, "at least one of the first, second, and third items" means a combination of all items derived from the first, second, and third items, as well as two or more of the first, second, or third items.

[0109] In the description of the embodiments, when a structure is described as being positioned "on" or "above" or "below" or "under" another structure, this description should be interpreted to include cases where the structures are in contact with each other and cases where a third structure is disposed therebetween. The dimensions and thicknesses of each element shown in the figures are given immediately for the convenience of description, and unless otherwise specified, the embodiments of this disclosure are not limited thereto.

[0110] As will be fully understood by those skilled in the art, the features of the various embodiments of this disclosure may be partially or entirely linked or combined with each other, and may interoperate differently and be technically driven. The embodiments of this disclosure may be performed independently of each other, or may be performed together in an interdependent manner.

[0111] In the following description, embodiments of the display device according to the present disclosure will be described in detail with reference to the accompanying drawings. When adding reference numerals to elements in each of the drawings, the same reference numerals may refer to the same elements even if the same elements are illustrated in other drawings. In the following description, detailed descriptions of related known functions or configurations will be omitted where it is determined that such detailed descriptions would unnecessarily obscure the essential points of the present disclosure. Furthermore, for ease of description, the scale of each element illustrated in the drawings differs from the actual scale; therefore, the description is not limited to the scale illustrated in the drawings.

[0112] The display device according to embodiments of the present disclosure may include a vibration generating module. When the display device is configured with a sound generating device as a vibration generating module, due to the complex structure of the display device, there is a problem that it is difficult to guarantee the sound of high-pitched vocal cords. To solve this problem, the display device according to embodiments of the present disclosure may further include a piezoelectric vibration device, which includes a piezoelectric material or a piezoelectric device having a strong piezoelectric effect (or inverse piezoelectric characteristics) with high-pitched vocal cord output. When such a piezoelectric vibration device is provided, the cost of the display device increases, and a separate element is required to realize the sound signal in the piezoelectric vibration device, thus leading to increased cost. Therefore, the inventors have conducted various experiments to realize the sound of high-pitched vocal cords without a piezoelectric vibration device. Through various experiments, the inventors have invented a display device with a novel structure. This will be described below.

[0113] Figure 1 An example of a display device according to an embodiment of the present disclosure is shown.

[0114] refer to Figure 1 According to embodiments of the present disclosure, a display device can output sound S1 based on the vibration of a display module 100 configured to display an image. For example, in the display device, the display module 100 can generate sound S1 by vibrating a vibration generating device (or a sound generating device). The sound S1 generated based on the vibration of the display module 100 can be directly output to the front area FD (or forward direction) of the screen in front of the display device. Therefore, by using the display module 100 as a vibrating plate for generating sound, the display device according to embodiments of the present disclosure can output sound S1 to the front area FD of the screen in front of the display device, thereby achieving accurate sound transmission, improving sound quality, and increasing the viewer's immersion.

[0115] Figure 2 The rear surface of a display device according to an embodiment of the present disclosure is illustrated. Figure 3 This is an exploded view of a display device according to an embodiment of the present disclosure. Figure 4 An example of a sound generating apparatus according to an embodiment of the present disclosure is shown. Figure 5 This is a top view of a display device according to an embodiment of the present disclosure. Figure 6 It is along Figure 3 The illustrated cross-sectional view taken by the I-I' line.

[0116] refer to Figures 2 to 6 The display device according to the embodiments of the present disclosure may include a display module 100, a support member 200, a back cover 300 and a vibration generating module 400.

[0117] The display module 100 may be a liquid crystal display module, but the embodiments of this disclosure are not limited thereto. For example, the display module 100 may be a display module such as a light-emitting display module, an electrophoretic display module, a micro light-emitting diode display module, an electrowetting display module, or a quantum dot light-emitting display module.

[0118] The rear cover 300 can be configured to support the support portion (or panel guide or panel guide section) 200 and can cover the rear surface of the display module 100. Furthermore, the rear cover 300 can be configured to support the vibration generating module 400. The rear cover 300 can also serve as a diaphragm, and therefore can include metallic or metal alloy materials. For example, the rear cover 300 can include materials selected from Fe, Al, Mg alloys, Mg-Li alloys, and Al alloys, but embodiments of this disclosure are not limited thereto. When the rear cover 300 includes a material containing non-ferrous metals, the sound of the bass band of the vibration generating module 400 can be further enhanced. For example, when the rear cover 300 includes ferrous metals, the sound characteristics of the vibration generating module 400 may be reduced due to vibration loss of the magnetic field of the vibration generating module 400. For example, the bass band can be 200Hz or lower, but embodiments of this disclosure are not limited thereto.

[0119] The rear cover 300 according to an embodiment of the present disclosure may further include: a rear portion 310 configured to support the rear surface of the display module 100; and a side portion 330 connected to the peripheral region EA of the rear portion 310 to support the support member 200.

[0120] The rear portion 310 can cover the rear surface of the display module 100 and support the display module 100. The rear portion 310 can have a plate structure, supporting the backlight portion 130 of the display module 100 and supporting the vibration generating module 400. For example, the rear portion 310 can directly contact the rear surface of the reflective sheet 133 and can transmit sound vibrations generated by the vibration of the vibration generating module 400 to the reflective sheet 133 of the backlight portion 130.

[0121] The rear portion 310 may include a central region MA that corresponds to (or overlaps with) the central portion of the display module 100 and a peripheral region EA that corresponds to (or overlaps with) the peripheral region of the display module 100.

[0122] Side portion 330 can be bent from the periphery of rear portion 310 and can be configured to support support member 200. Side portion 330 can provide a backlight receiving space on rear portion 310 and can surround the side surface of backlight portion 130 housed in (or supported by) backlight receiving space. Side portion 330 can transmit sound vibrations generated by vibration generating module 400 in rear portion 310 to support member 200.

[0123] The rear cover 300 according to the embodiments of the present disclosure may further include a reinforcing portion 350. The reinforcing portion 350 can enhance the rigidity of the rear cover 300, and therefore may be referred to as a rigidity reinforcing portion, but the embodiments of the present disclosure are not limited thereto.

[0124] The reinforcing portion 350 may be disposed in the region (or connecting region) where the rear portion 310 intersects with the side portion 330. For example, the reinforcing portion 350 may be disposed along the peripheral region EA of the rear portion 310. For example, the reinforcing portion 350 may protrude rearward to have an inclined surface that slopes from the end of the rear portion 310. When the rear cover 300 includes the reinforcing portion 350, the side portion 330 may be connected to the end of the reinforcing portion 350.

[0125] The display device according to embodiments of the present disclosure may further include a system back cover 600 on the rear surface of the back cover 300.

[0126] The system rear cover 600 can accommodate the display module 100, which is provided with the vibration generating module 400, and can surround the side surface of the display module 100. For example, the system rear cover 600 can be referred to as a collection cover, rear collection cover, outermost collection cover, product cover, or outermost product cover, but the embodiments of this disclosure are not limited thereto.

[0127] The rear surface (or back surface) of the display module 100 may include a central region MA and a peripheral region EA. For example, the rear surface (or back surface) of the display module 100 may be divided into a central region MA and a peripheral region EA. The vibration generating module 400 may be disposed in the peripheral region EA of the display module 100.

[0128] The vibration generating module 400 may include a first sound generating device 410 and a second sound generating device 430. According to embodiments of this disclosure, the first sound generating device 410 and the second sound generating device 430 may be disposed in the peripheral region EA of the rear cover 300. For example, the first sound generating device 410 and the second sound generating device 430 may be disposed along the peripheral region EA of the rear cover 300. For example, the orientation of the first sound generating device 410 and the second sound generating device 430 may be configured to be symmetrical or asymmetrical with respect to the center of the display module 100 in a first direction X (or width direction) relative to the display module 100.

[0129] The display panel 110 according to embodiments of the present disclosure may include a first substrate 111, a second substrate 113, a second polarizing member 115 and a first polarizing member 117.

[0130] The first substrate 111 may be an upper substrate or a thin-film transistor (TFT) array substrate, and may include a pixel array (or display section or display area), which includes multiple pixels in multiple pixel areas corresponding to the intersection of multiple gate lines and / or multiple data lines. Each of the multiple pixels may include: a TFT connected to the gate line and / or data line; a pixel electrode connected to the TFT; and a common electrode disposed adjacent to the pixel electrode and supplied with a common voltage.

[0131] The first substrate 111 may further include pad portions in its first periphery (or its first non-display portion) and gating drive circuitry in its second periphery (or its second non-display portion).

[0132] The pad portion can provide externally supplied signals to the pixel array and / or gating drive circuitry. For example, the pad portion can include multiple data pads connected to multiple data lines via multiple data link lines, and multiple gating input pads connected to the gating drive circuitry via gating control signal lines. A first periphery of the first substrate 111 including the pad portion can protrude from a corresponding side surface of the first periphery of the second substrate 113, and the pad portion can be exposed toward the rear cover 300 in a rearward direction. For example, the size of the first substrate 111 can be larger than the size of the second substrate 113, but embodiments of this disclosure are not limited thereto.

[0133] The gating drive circuit according to embodiments of the present disclosure can be embedded (or integrated) into a second periphery of the first substrate 111 to connect to a plurality of gating lines. For example, the gating drive circuit may be a shift register comprising transistors formed by the same process as forming TFTs in each of the pixel regions. As another example, the gating drive circuit may be configured as an integrated circuit without being embedded in the first substrate 111 and may be included in a panel drive circuit.

[0134] The second substrate 113 may be a lower substrate or a color filter array substrate, and may include a pixel pattern comprising an opening region overlapping each of the pixel regions on the first substrate 111 and a color filter layer in the opening region. The size of the second substrate 113 according to embodiments of the present disclosure may be smaller than the size of the first substrate 111, but embodiments of the present disclosure are not limited thereto. For example, the second substrate 113 may overlap with a portion of the first substrate 111 other than the first periphery. The second substrate 113 may be attached to the portion of the first substrate 111 other than the first periphery using a sealant via a liquid crystal layer between the second substrate 113 and the first substrate 111.

[0135] The liquid crystal layer may be located between the first substrate 111 and the second substrate 113, and may include liquid crystal comprising liquid crystal molecules having an orientation that changes based on an electric field generated from a common voltage supplied to each of the pixel electrodes in the plurality of pixels and a data voltage.

[0136] The second polarizing member 115 can be located on the lower surface of the second substrate 113 and can polarize the light that is irradiated from the backlight portion 130 and propagates to the liquid crystal layer.

[0137] The first polarizing member 117 can be located on the upper surface of the first substrate 111 and can polarize the light that passes through the first substrate 111 and is output to the outside.

[0138] According to an embodiment of the present disclosure, the display panel 110 can drive the liquid crystal layer based on the electric field generated from the common voltage and data voltage applied to the pixel electrodes of each of the plurality of pixels, thereby displaying an image formed by using light passing through the liquid crystal layer.

[0139] Because the first substrate 111, which serves as the TFT array substrate, is configured with an image display surface, the entire front surface of the display panel 110 according to the embodiment can be exposed externally without being covered by a separate mechanism.

[0140] According to another embodiment of the present disclosure, in the display panel 110, the first substrate 111 may be a color filter array substrate, and the second substrate 113 may be a TFT array substrate. For example, the display panel 110 according to another embodiment of the present disclosure may have a type in which the upper and lower portions of the display panel 110 according to the embodiment of the present disclosure are inverted therebetween. For example, the pad portion of the display panel 110 according to another embodiment of the present disclosure may be covered by a separate mechanism or structure.

[0141] The display module 100 according to embodiments of the present disclosure may further include a buffer member 150. The buffer member 150 may surround the side surfaces of the display panel 110. The buffer member 150 may cover each side surface and each corner of the panel. The buffer member 150 may protect the side surfaces of the display panel 110 from external impacts or may prevent light leakage through the side surfaces of the display panel 110. The buffer member 150 may include a silicone-based sealant or a UV-curable sealant (or resin), but considering production cycle time, the buffer member 150 may include a UV-curable sealant. Additionally, the buffer member 150 may have a color (e.g., blue, red, turquoise, or black), but embodiments of the present disclosure are not limited thereto. For example, the buffer member 150 may include a colored resin or a light-shielding resin for preventing light leakage through the side surfaces.

[0142] A portion of the upper surface of the buffer member 150 according to embodiments of the present disclosure may be covered by the first polarizing member 117. For example, the first polarizing member 117 may include an extension surface extending from a side surface corresponding to the outer surface of the first substrate 111 to cover a portion of the front surface of the buffer member 150, and attached to a portion of the front surface of the buffer member 150. The bonding or attachment surface between the buffer member 150 and the first substrate 111 (or the boundary between the buffer member 150 and the first substrate 111) may be hidden by the extension of the first polarizing member 117 and may not be exposed in the forward area where the viewer is located in front of the display device. Without the buffer member 150, the front surface of the display panel 110 may be exposed in the forward area FD in front of the display device without a separate mechanism, and light leakage through the side surface of the display panel 110 may occur. Therefore, in order to eliminate or minimize the bezel width of the display device, in a display device having a structure in which the entire front surface of the display panel 110 is exposed at the forward region FD, a buffer member 150 may be provided to prevent light leakage through the side surface of the display panel 110 and to protect the side surface of the display panel 110. However, embodiments of the present disclosure are not limited thereto, and the buffer member 150 may be omitted.

The light guiding component 131 may include a light-transmitting plastic or glass material. The light guiding component 131 can transmit (or output) light incident from the light source unit through the light incident surface to the display panel 110. For example, the light guiding component 131 may be referred to as a light guiding member or a planar light source, but embodiments of this disclosure are not limited thereto.

[0145] The light source component can illuminate light onto the light incident surface in the light guiding component 131. The light source component can be disposed on the rear cover 300 to overlap with the first periphery of the display panel 110. The light source component according to an embodiment of the present disclosure may include a plurality of light-emitting diode (LED) devices mounted on a light source printed circuit board (PCB) and illuminating light onto the light incident surface of the light guiding component 131.

[0146] A reflector 133 may be disposed on the rear cover 300 to cover the rear surface of the light guiding member 131. The reflector 133 can reflect light incident from the light guiding member 131 toward the light guiding member 131 to minimize or reduce light loss.

[0147] Optical sheet component 135 can be disposed on the front surface of light guiding component 131 and can enhance the luminance characteristics of light output from light guiding component 131. According to embodiments of the present disclosure, optical sheet component 135 may include a second diffuser, a second prism sheet, and a first prism sheet. For example, optical sheet component 135 may be configured as a single layer comprising a second diffuser, a second prism sheet, and a first prism sheet, but embodiments of the present disclosure are not limited thereto. For example, optical sheet component 135 may be composed of a stacked combination of one or more of diffuser, prism sheet, dual brightness enhancement film (DBEF), and biconvex lens sheet, or may be composed of a composite sheet having light diffusion and light focusing functions.

[0148] The support member 200 can support the rear peripheral region EA of the display panel 110. The support member 200 can be supported by or housed in the rear cover 300 to overlap with the rear peripheral region EA of the display panel 110. The support member 200 can be disposed below the rear peripheral region EA of the display panel 110 without protruding beyond the exterior of each side surface of the display panel 110.

[0149] The support member 200 may include a support portion 210 and a guide sidewall 230. For example, the support member 200 may have a cross-sectional structure with a ┓ or ┏ shape based on the connection or linking structure of the support portion 210 and the guide sidewall 230.

[0150] The support portion 210 can be coupled to or connected to the rear peripheral region EA of the display panel 110 and can be supported by the rear cover 300. For example, the support portion 210 may have a shape including a quadrangular strip (or band) that overlaps with the central region MA of the display panel 110 excluding the rear peripheral region EA, but embodiments of the present disclosure are not limited thereto. The size of the support portion 210 may be equal to or smaller than the size of the display panel 110 so as not to protrude beyond the exterior of each side surface of the display panel 110. For example, the opening of the support portion 210 may have a size equal to or larger than the size of the pixel array (or display section) in the display panel 110.

[0151] The support portion 210 can directly contact the uppermost surface of the backlight portion 130 (e.g., the uppermost surface of the optical sheet component 135), or it can be separated from the uppermost surface of the optical sheet component 135 by a certain distance.

[0152] The guide sidewall 230 can be connected to the support portion 210 and can surround the side surface of the rear cover 300. For example, the guide sidewall 230 can be bent from the support portion 210 to the side surface of the rear cover 300 and can surround the side surface of the rear cover 300, or can be surrounded by the side surface of the rear cover 300.

[0153] The support member 200 according to embodiments of the present disclosure may include a plastic material, a metal material, or a mixture of plastic and metal materials, but embodiments of the present disclosure are not limited thereto. For example, the support member 200 may serve as a vibration transmission member that transmits sound vibrations generated by the vibration generating module 400 to the rear peripheral region EA of the display panel 110. Therefore, the support member 200 can transmit sound vibrations generated by the vibration generating module 400 to the display panel 110 without loss while maintaining the rigidity of the display panel 110. For example, the support member 200 may include a metal material for transmitting sound vibrations generated by the vibration generating module 400 to the display panel 110 without loss while maintaining the rigidity of the display panel 110, but embodiments of the present disclosure are not limited thereto.

[0154] According to embodiments of the present disclosure, the support member 200 can be connected or attached to the rear peripheral area EA of the display panel 110 via the first connecting member 250.

[0155] The first connecting member 250 may be located between the rear peripheral region EA of the display panel 110 and the support portion 210 of the support member 200, and may be disposed on or attached to the support member 200. The first connecting member 250 according to embodiments of the present disclosure may include an acrylic adhesive member or a urethane-based adhesive member, but embodiments of the present disclosure are not limited thereto. For example, the first connecting member 250 may include an acrylic adhesive member with relatively good adhesion and hardness, such that vibrations of the support member 200 can be well transmitted to the display panel 110. For example, the first connecting member 250 may include a double-sided foam adhesive pad having an acrylic adhesive layer or an acrylic adhesive resin cured layer.

[0156] According to embodiments of the present disclosure, the front surface of the first connecting member 250 can be coupled to or connected to the second substrate 113 or the second polarizing member 115 of the display panel 110. For example, the first connecting member 250 can be directly coupled to or connected to the rear peripheral region EA of the second substrate 113 to enhance the adhesion between the first connecting member 250 and the display panel 110. For example, the first connecting member 250 can be attached to the rear peripheral region EA of the second substrate 113 and can surround the side surface of the second polarizing member 115 to prevent light leakage from the side surface in the second polarizing member 115.

[0157] The first connecting member 250 can provide a sound transmission space STS between the display panel 110 and the support member 200, having a certain thickness (or height). According to embodiments of the present disclosure, the first connecting member 250 can have a four-sided closed shape or a closed loop shape on the support portion 210 of the support member 200, but embodiments of the present disclosure are not limited thereto. For example, the first connecting member 250 can provide a closed sound transmission space STS between the last surface of the display panel 110 and the uppermost surface of the backlight portion 130, the uppermost surface of the backlight portion 130 and the opening of the support member 200 therebetween facing each other, thereby preventing or minimizing leakage (or loss) of sound pressure transmitted to the sound transmission space STS. The sound transmission space STS can also be used as a space for sound generation based on the vibration of the backlight portion 130 to produce sound pressure, or as a panel vibration space that allows the vibration of the display panel 110 to proceed smoothly.

[0158] refer to Figures 2 to 6 The vibration generating module 400 can be disposed in the peripheral area EA of the rear cover 300. For example, the vibration generating module 400 can be disposed along the peripheral area EA of the rear cover 300.

[0159] The vibration generating module 400 can be disposed in the rear region of the rear cover 300 and can cause the region of the display module 100 to vibrate. For example, the region of the display module 100 can overlap with the peripheral region EA of the display module 100, and the region of the display module 100 can be the peripheral region EA of the display module 100.

[0160] The vibration generating module 400 according to embodiments of the present disclosure can be coupled to or disposed on a peripheral region EA in the rear portion 310 of the rear cover 300. Therefore, in response to an external sound signal (or voice signal) input, the vibration generating module 400 can cause the peripheral region EA of the rear portion 310 to vibrate to generate sound pressure, and can utilize the sound pressure to cause the peripheral region EA of the display panel 110 to vibrate to generate sound S1. The vibration generating module 400 according to embodiments of the present disclosure may include a sound actuator or a sound exciter, but embodiments of the present disclosure are not limited thereto. For example, the vibration generating module 400 may be implemented as a sound generating device using a coil (or voice coil) and a magnet.

[0161] Figure 4 An example of a sound generating apparatus according to an embodiment of the present disclosure is shown.

[0162] The vibration generating module 400 according to embodiments of the present disclosure may include a first sound generating device 410 and a second sound generating device 430.

[0164] The module frame 401 may be supported by the rear portion 310. According to embodiments of the present disclosure, the module frame 401 may include a frame body 401a, a first plate 401b, and a support 401c.

[0165] The frame body 401a can be fixed to the rear 310, and the frame body 401a can be used as a lower plate or a second plate that can support the magnet component 403.

[0166] The first plate 401b may be disposed around the periphery of the front surface of the frame body 401a, having a cylindrical shape including a hollow portion. The frame body 401a and the first plate 401b may be configured as a single body having a U-shape. For example, the frame body 401a and the first plate 401b are not limited to these terms and may be referred to as a yoke, etc.

[0167] The bracket or fixed bracket 401c can protrude from the side surface of the upper plate 401b. The bracket 401c can be fixed to the rear part 310 by means of a module connecting member, and thereby the module frame 401 can be fixed to the rear part 310.

[0168] According to embodiments of the present disclosure, the module connecting member may be a screw or bolt that can pass through the bracket 401c and can be connected to the rear portion 310 of the rear cover 300. For example, a buffer ring may be located between the rear portion 310 of the rear cover 300 and the bracket 401c, and the buffer ring may prevent vibrations of the rear portion 310 from being transmitted to the module frame 401.

[0169] The module connecting member according to embodiments of the present disclosure can fix the bracket 401c or the module frame 401 to the rear portion 310. For example, the module connecting member may include an adhesive member disposed between the bracket 401c and the rear portion 310. For example, the adhesive member may include single-sided tape, single-sided adhesive pad, single-sided adhesive gap pad, single-sided adhesive foam pad, double-sided tape, double-sided adhesive pad, double-sided adhesive gap pad, or double-sided adhesive foam pad, but embodiments of the present disclosure are not limited thereto.

[0170] The spool 402 can be mounted on the module frame 401 and can cause the rear portion 310 of the rear cover 300 to vibrate. According to embodiments of the present disclosure, the spool 402 can have a cylindrical shape including a hollow portion 402a and can be attached to the rear surface of the rear portion 310. For example, the spool 402 can have an annular structure formed from materials produced by processing pulp or paper, Al or Mg, or alloys thereof, such as synthetic resins like polypropylene or polyamide-based fibers, but embodiments of the present disclosure are not limited thereto. The spool 402 can vibrate based on magnetic force and, for example, can perform a vertical reciprocating motion, thereby causing the rear cover 300 to vibrate.

[0171] The spool 402 according to embodiments of the present disclosure may have a circular or elliptical (or elliptical) shape, but embodiments of the present disclosure are not limited thereto. The spool 402 with an elliptical shape may have an elliptical shape, a rounded rectangular shape, or a non-circular curved shape with a width different from its height, but embodiments of the present disclosure are not limited thereto. For example, in the spool 402 with an elliptical shape, the ratio of the major axis diameter to the minor axis diameter may be 1.3:1 to 2:1. The spool 402 with an elliptical shape can improve the high-pitched sound band more than the spool 402 with a circular shape, and can reduce heat generated by vibration; therefore, the spool 402 with an elliptical shape can have good heat dissipation characteristics.

[0172] A magnet component 403 can be disposed on the module frame 401 to be housed in the hollow portion 402a of the wire cylinder 402. The magnet component 403 can be a permanent magnet with a cylindrical shape to be housed in the hollow portion 402a of the wire cylinder 402. The magnet component 403 according to embodiments of the present disclosure can be implemented using a sintered magnet such as barium ferrite, and the material of the magnet component 403 can include one or more of the following: ferric oxide (Fe₂O₃); barium carbonate (or barium carbonate) (BaCO₃); neodymium (Nd); strontium ferrite (Fe₂O₃) with an improved magnet composition. 12 O 19 Sr); and cast magnets comprising alloys such as aluminum (Al), nickel (Ni), and cobalt (Co), but the embodiments of this disclosure are not limited thereto. For example, neodymium magnets may be neodymium iron boron (Nd-Fe-B), but the embodiments of this disclosure are not limited thereto.

[0173] Coil 404 can be wound to surround the outer peripheral surface of the bobbin 402 and can be supplied with sound signals (or voice signals) from the outside. Coil 404 can be raised or lowered together with bobbin 402. When a sound signal (or current) is applied to coil 404, the entire portion of bobbin 402 can vibrate, for example, performing a vertical reciprocating motion based on the applied magnetic field generated around coil 404 and the external magnetic field generated around magnet member 403, according to Fleming's left-hand rule. For example, coil 404 can be referred to as a voice coil, but embodiments of this disclosure are not limited thereto.

[0174] The center pole 405 can be on the magnet component 403 and can guide the vibration of the bobbin 402. For example, the center pole 405 can be inserted into or accommodated in the hollow portion of the bobbin 402 and can be surrounded by the bobbin 402. For example, the center pole 405 can be referred to as an "elevation guide" or "pole plate", but the embodiments of this disclosure are not limited thereto.

[0175] A damper 406 may be located between the module frame 401 and the spool 402. For example, the damper 406 may be located between the frame body 401a of the module frame 401 and the upper outer peripheral surface of the spool 402. The damper 406 may be provided in the form of a crease structure, which may be creased between its ends and may contract and relax based on the vibration of the spool 402. The vibration distance (or vertical movement distance) of the spool 402 may be limited by the restoring force of the damper 406. As an example, when the spool 402 vibrates a certain distance or more or less, the spool 402 may be restored to its original position by the restoring force of the damper 406. For example, the damper 406 may be referred to as a "spider," "suspension," or "edge," but embodiments of this disclosure are not limited thereto.

[0176] Each of the first sound generating device 410 and the second sound generating device 430 according to embodiments of the present disclosure may be referred to as internal magnetic type (or miniature type) such that the magnet member 403 can be inserted into the hollow portion 402a of the spool 402.

[0177] Each of the first sound generating apparatus 410 and the second sound generating apparatus 430 according to another embodiment of this disclosure may be referred to as an external magnetic type (or dynamic type), such that the magnet member 403 is arranged to surround the exterior of the bobbin 402. For example, except that the magnet member 403 may be disposed between the frame body 401a and the first plate 401b, and the center pole 405 may be disposed on the second plate (such as the frame body 401a) to be inserted into or accommodated in the hollow portion of the bobbin 402, the external magnetic type sound generating apparatuses 410 and 430 may be substantially similar to the internal magnetic type. Therefore, detailed description is omitted.

[0178] Each of the first sound generating device 410 and the second sound generating device 430 according to embodiments of the present disclosure may further include a spool protection member 407 between the upper portion of the spool 402 and the rear portion 310 of the rear cover 300.

[0179] The spool protection member 407 can be provided in a cylindrical structure, which includes an opening overlapping the hollow portion 402a of the spool 402, and can be provided or connected to the upper surface of the spool 402. The spool protection member 407 can cover the upper surface of the spool 402 to protect the spool 402, thereby preventing the spool 402 from deforming due to external impact.

[0180] The spool protection member 407 according to embodiments of the present disclosure can be provided in a molded form as a molded product of injection-molded material or metal. For example, the spool protection member 407 may include a fabric reinforcement material, a composite resin including a fabric reinforcement material, or a metal, and may, for example, have a heat dissipation function to dissipate heat generated when the first sound generating device 410 and the second sound generating device 430 are activated. The fabric reinforcement material may be one of carbon fiber reinforced plastic (CFRP), glass fiber reinforced plastic (GFRP), and graphite fiber reinforced plastic (GFRP), or a combination thereof, but embodiments of the present disclosure are not limited thereto.

[0181] The spool protection member 407 can be attached to or connected to the spool 402 by double-sided tape or adhesive resin. For example, the adhesive resin can be epoxy resin or acrylic resin, but the embodiments of this disclosure are not limited thereto.

[0182] The spool protection component 407 can be connected or attached to the rear part 310 of the rear cover 300 by double-sided tape or adhesive resin.

[0183] refer to Figure 6 The display module 100 according to the embodiments of the present disclosure may include a display panel 110 and a backlight portion 130.

[0184] The display panel 110 can be configured to display an image using light emitted from the backlight section 130. The display panel 110 can also act as a vibrating plate, vibrating based on the vibration of the vibration generation module 400 to output sound S1 to the forward region FD in front of the display panel 110. For example, the display panel 110 can output sound S1 based on the vibration of the vibration generation module 400.

[0185] The first sound generating device 410 can cause the first peripheral region EA1 (or left peripheral region) of the peripheral area EA of the display module 100 to vibrate, so as to output the sound S1 to the front area FD in front of the display panel 110. For example, when the first sound generating device 410 vibrates based on the sound signal, the first peripheral region EA1 (or first rear region) of the rear part 310 can vibrate based on the vibration of the first sound generating device 410 to generate sound pressure in the gap space GS (or sound output space) between the first sound generating device 410 and the rear cover 300, so that the first peripheral region EA1 of the display module 100 vibrates to generate the sound S1. For example, when the first sound generating device 410 vibrates according to a sound signal, the first peripheral region EA1 of the rear portion 310 can vibrate based on the vibration of the first sound generating device 410 to generate sound pressure in the gap space GS. The backlight portion 130 can vibrate based on the generated sound pressure to generate sound pressure in the sound transmission space STS, and the display panel 110 can vibrate based on the sound pressure transmitted to the sound transmission space STS to generate sound S1, thereby outputting sound S1 to the forward region FD in front of the display panel 110. Therefore, the sound wave (or sound pressure) generated based on the vibration of the first sound generating device 410 can be directly transmitted (or propagated) to the display module 100, thereby enhancing the sound pressure characteristics and sound quality of sound S1.

[0186] The second sound generating device 430 can cause the second peripheral region EA2 (or the right peripheral region) of the peripheral region EA of the display module 100 to vibrate, so as to output the sound S1 to the front region FD in front of the display panel 110. For example, when the second sound generating device 430 vibrates based on the sound signal, the second peripheral region EA2 (or the second rear region) of the rear portion 310 can vibrate based on the vibration of the second sound generating device 430 to generate sound pressure in the gap space GS (or sound output space) between the second sound generating device 410 and the rear cover 300, thereby causing the second peripheral region EA2 of the display module 100 to vibrate to generate the sound S1. For example, when the second sound generating device 430 vibrates according to the sound signal, the second peripheral region EA2 of the rear portion 310 can vibrate based on the vibration of the second sound generating device 430 to generate sound pressure in the gap space GS. The backlight portion 130 can vibrate based on the generated sound pressure to generate sound pressure in the sound transmission space STS, and the display panel 110 can vibrate based on the sound pressure transmitted to the sound transmission space STS to generate sound S1, thereby outputting sound S1 to the forward region FD in front of the display panel 110. Therefore, the sound wave (or sound pressure) generated based on the vibration of the second sound generating device 430 can be directly transmitted (or propagated) to the display module 100, thereby enhancing the sound pressure characteristics and sound quality of sound S1.

[0187] refer to Figures 3 to 6According to embodiments of the present disclosure, the first sound generating device 410 and the second sound generating device 430 can be disposed at the rear periphery of the rear cover 300. For example, the sound generating device 410 and the second sound generating device 430 can be disposed separately from the rear surface of the rear cover 300. For example, the first sound generating device 410 and the second sound generating device 430 can be disposed on the rear cover 300 via a second connecting member 800. For example, the second connecting member 800 can be disposed between the first sound generating device 410 and the rear cover 300, and can also be disposed between the second sound generating device 430 and the rear cover 300.

[0188] The second connecting member 800 can be implemented to include an opening or opening region to address the problem that the sound generated by the first sound generating device 410 and the second sound generating device 430 is blocked between each of the first sound generating device 410 and the second sound generating device 430 and the rear cover 300. For example, the second connecting member 800 may include an opening or opening region disposed on its side surface. For example, the second connecting member 800 may have a structure with its side surface open. For example, one side surface of the second connecting member 800 may be open. For example, the sound from the first sound generating device 410 and the second sound generating device 430 can be output through one side of the second connecting member 800 to a lateral region (or lateral direction) in the side surface of the rear cover 300. Therefore, the first sound generating device 410 and the second sound generating device 430 can be disposed at the rear cover 300, and the sound from the first sound generating device 410 and the second sound generating device 430 can be output to the rear region of the side surface of the rear cover 300 and the rearward region (or rearward direction) of the lateral region.

[0189] refer to Figure 6 The sounds from the first sound generating device 410 and the second sound generating device 430 can be output in the rearward and lateral directions of the rear cover 300 through the second connecting member 800, which includes an opening or an opening region. Therefore, the path of the sounds generated by the first sound generating device 410 and the second sound generating device 430 can be the first sound path SP1. For example, when the first sound generating device 410 and the second sound generating device 430 are provided, the problem of not outputting high-pitched vocal cord sounds due to sounds output through or via the first sound path SP1 can be solved.

[0190] refer to Figures 4 to 6The vibration generating module 400 according to embodiments of the present disclosure may further include a first hole 409. The first hole 409 can prevent dust or particles from flowing into the vibration generating module 400 due to the second connecting member 800 including an opening or opening area. For example, the first hole 409 may include a plurality of holes communicating with the space between the periphery of the rear cover 300 and the first sound generating device 410 and the second sound generating device 430. The first hole 409 may have a mesh structure, but embodiments of the present disclosure are not limited thereto. For example, the first hole 409 may be provided at a cover 408 located near the bracket 401c. The cover 408 may be implemented independently of the bracket 401c, but embodiments of the present disclosure are not limited thereto. For example, the cover 408 may be integrally provided with the bracket 401c. For example, the cover 408 may be implemented to cover or close all or part of the opening (or opening area) of the second connecting member 800.

[0191] Therefore, in the vibration generating module 400 according to an embodiment of the present disclosure, a connecting member can be provided, which is disposed in the peripheral region EA of the rear cover 300 and between the rear cover 300 and the vibration generating module 400, and whose side or one side surface is open, so that sound can be output relative to the rear cover in the rearward and lateral directions. For example, in the sound generating devices 410 and 430 according to embodiments of the present disclosure, a connecting member can be provided, which is disposed in the peripheral region EA of the rear cover 300 and between the rear cover 300 and the sound generating devices 410 and 430, and whose side or one side surface is open, so that sound can be output relative to the rear cover in the rearward and lateral directions. Therefore, a display device including a vibration generating module for outputting high-pitched vocal cord sound can be provided.

[0192] Figure 7 This is an exploded view of a display device according to another embodiment of the present disclosure. Figure 8 A display device according to another embodiment of the present disclosure is illustrated.

[0193] refer to Figure 7 and Figure 8 According to another embodiment of the present disclosure, the display device may include a display module 100, a support member 200, a back cover 300, a vibration generating module 400, and a structure 900.

[0194] According to embodiments of the present disclosure, the structure 900 can be disposed on one side or a portion of the display module 100. For example, since the structure 900 is disposed on one side or a portion of the display module 100, the sounds from the first sound generating device 410 and the second sound generating device 430 can be reflected by the structure 900 and output in the forward direction relative to the display module 100. For example, the structure 900 can be a sound guiding structure that guides the sound of the vibration generating module 400 to be output in the forward or lateral direction of the display module 100. For example, a connecting member in which the structure 900 and / or one side or one side surface is open can be a sound guiding structure that guides the sound of the vibration generating module 400 to be output in the forward or lateral direction of the display module 100. The sound of the vibration generating module 400 can be reflected by the side surface of the structure 900 and output in the forward direction of the display module 100, thereby providing a display device for outputting high-pitched vocal cord sound.

[0195] For example, structure 900 may include a bottom 910, a sound guide 920, a side portion 930, and a recess 950. The recess 950 may be a portion where the vibration generating module 400 is disposed and may be located on one side (or part) of the bottom 910. The bottom 910 may be located on the rear surface of the rear cover 300. The side portion 930 may be spaced apart from one side surface or part of the display module 100 and may be connected to the bottom 910. The sound guide 920 may be located between the bottom 910 and the side portion 930, and may be a corner portion between the inner surface of the side portion 930 and the bottom 910. For example, the sound guide 920 may allow the sound from the vibration generating module 400 to be reflected by the sound guide 920 and output in the positive direction of the display module 100. Therefore, the sound from the vibration generating module 400 may be configured to be reflected by structure 900 and output in the positive direction of the display module 100. For example, the sounds from the first sound generating device 410 and the second sound generating device 430 can be configured to be reflected by the structure 900 and output in the forward direction of the display module 100. For example, the sound guide 920 can be implemented as a curved shape or a rounded corner shape. For example, when the sound guide 920 has a curved shape or a rounded corner shape, the reflection of sound propagating in the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300 can be further enhanced. For example, the path of the sound generated by the vibration generating module 400 can be a second sound path SP2. For example, the path of each of the sounds generated by the first sound generating device 410 and the second sound generating device 430 can be the second sound path SP2. For example, the second sound path SP2 can include the forward direction and the lateral direction of the display module 100. For example, the second sound path SP2 can include the forward direction (or the thickness direction of the display module) and the lateral direction of sound propagation in the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300. For example, the second sound path SP2 may include the positive and lateral directions of sound reflected from the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300, and may include the positive and lateral directions of sound output through or via the second connecting member 800.

[0196] Figure 9 A display device according to another embodiment of the present disclosure is illustrated. Even without further examples, the rear surface of the back cover or the back cover itself may be tilted.

[0197] refer to Figure 9The vibration generating module 400 can be configured to be inclined relative to the rear surface of the rear cover 300. For example, the vibration generating module 400 can be configured to be inclined via a second connecting member 800 with one side (or part) open. For example, the vibration generating module 400 can be inclined at the height of the second connecting member 800. For example, the second connecting member 800 can have a height that gradually decreases from one part to another part opposite to that one part. For example, the second connecting member 800 can include a first side parallel to one part of it, a second side connected to one end (or part) of the first side, and a third side connected to another end (or part) of the first side parallel to the second side, and each of the second and third sides can have a lower height (thickness) closer to the first side.

[0198] For example, the tilt angle of the vibration generating module 400 can vary from one side (or part) of the rear cover 300 to the other side (or part) of the rear cover 300, thereby amplifying the sound output at the side surface of the display module 100. For example, when one side (or part) of the second connecting member 800 is one side (or part) of the rear cover 300, the tilt angle of the vibration generating module 400 can increase from one side of the rear cover 300 to the other side (or part) of the rear cover 300. Therefore, the sound from the vibration generating module 400 can be effectively output at the other side (or part) of the second connecting member 800, where one side (or part) is open. For example, the sound from the vibration generating module 400 can be reflected between the vibration generating module 400 and the rear surface of the rear cover 300, and can be output in the forward direction of the display module 100. For example, the sound from the vibration generating module 400 can be reflected by the side surface of the structure 900 and can be output in the forward direction of the display module 100. For example, the tilted vibration generating module 400 and a second connecting member 800 with one side (or part) or one side surface open may include a sound guiding structure that guides the sound of the vibration generating module 400 to be output in the forward or lateral direction of the display module 100. For example, the tilted vibration generating module 400 with one side (or part) or one side surface open, the second connecting member 800, and / or structure 900 may include a sound guiding structure that guides the sound of the vibration generating module 400 to be output in the forward or lateral direction of the display module 100. Therefore, by providing a connecting member with one side or one side surface open, the sound of the vibration generating module 400 can be output in the lateral direction. The tilted vibration generating module 400 can increase the area where sound is reflected between the back cover 300 and the vibration generating module 400, and the sound can be reflected by the side surface of the structure 900 and can be output in the forward direction of the display module 100, thereby further enhancing the sound characteristics of the high-pitched vocal cords.

[0199] For example, the sound path generated by the vibration generating module 400 can be a third sound path SP3. For example, the sound path generated by the first sound generating device 410 and the second sound generating device 430 can be a third sound path SP3. For example, the third sound path SP3 can be the forward direction (or the thickness direction of the display module) and the lateral direction of sound reflected from the rear surface of the display module 100. For example, the third sound path SP3 can be the forward direction and the lateral direction of sound reflected from the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300, and can also be the forward direction and the lateral direction of sound output through the second connecting member 800. For example, the third sound path SP3 can be the forward direction and the lateral direction of sound reflected from the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300, and can also be the forward direction of sound reflected from the side surface of the structure 900. Therefore, a display device for further enhancing the sound of high-pitched vocal cords can be provided.

[0200] Figure 10 The rear surface of a display device according to another embodiment of the present disclosure is illustrated. Figure 11 This is a top view of a display device according to another embodiment of the present disclosure. Figure 12 A display device according to another embodiment of the present disclosure is illustrated. Figures 10 to 12 Examples are shown by modifying Figure 8 The embodiments of this disclosure are implemented by means of the structure of the back cover in the illustrated display device. Therefore, the back cover will be described in detail below, and other components will be described in terms of their relationship with the back cover. Figure 8 The same reference numerals refer to the same items, and their repeated descriptions are omitted or will be given briefly.

[0201] refer to Figures 10 to 12 According to another embodiment of the present disclosure, the display device may include a display module 100, a support member 200, a back cover 300, a vibration generating module 400, and a structure 900.

[0202] According to another embodiment of the present disclosure, the back cover 300 may further include at least one second hole 420. The at least one second hole 420 may overlap with the vibration generating module 400. For example, the at least one second hole 420 may overlap with the first sound generating device 410 and the second sound generating device 430. For example, the at least one second hole 420 may be formed by a patterning process or a drilling process performed on the back cover 300, but embodiments of the present disclosure are not limited thereto.

[0203] For example, at least one second hole 420 can enhance the sound reflection characteristics between the back cover 300 and the vibration generating module 400, thereby enhancing the sound of the high-pitched vocal cords. For example, at least one second hole 420 can enhance the sound reflection characteristics between the back cover 300 and the first sound generating device 410 and the second sound generating device 430, thereby enhancing the sound of the high-pitched vocal cords. For example, a back cover 300 including at least one second hole 420 and a connecting member 800 with one side (or part) or one side surface open can include a sound guiding structure for guiding the sound of the vibration generating module 400 to be output in the forward or lateral direction of the display module 100. For example, a back cover 300 including at least one second hole 420 can include a sound guiding structure for guiding the sound of the vibration generating module 400 to be output in the forward or lateral direction of the display module 100. For example, a back cover 300 including at least one second hole 420 can include a sound guiding structure for guiding the sound of the first sound generating device 410 and the second sound generating device 430 to be output in the forward or lateral direction of the display module 100. For example, a rear cover 300 and / or structure 900 including at least one second hole 420 and a connecting member 800 with one side (or part) or one side surface open may include a sound guiding structure that guides the sound of the vibration generating module 400 to be output in the forward or lateral direction of the display module 100. For example, a rear cover 300 including at least one second hole 420 and / or structure 900 may include a sound guiding structure that guides the sound of the first sound generating device 410 and the second sound generating device 430 to be output in the forward or lateral direction of the display module 100.

[0204] For example, the sound from the vibration generating module 400 can pass through or be output via the second hole 420 in the forward direction of the display module 100. For example, the sound from the first sound generating device 410 and the second sound generating device 430 can pass through or be output via the second hole 420 in the forward direction of the display module 100. For example, the path of the sound generated by the first sound generating device 410 and the second sound generating device 430 through the second hole 420 can be a fourth sound path SP4. For example, the fourth sound path SP4 can be both in the forward direction (or the thickness direction of the display module) and the lateral direction, in which the sound is output from the rear surface of the display module 100 through or via the second hole 420. For example, the fourth sound path SP4 can be in the forward direction of the sound output in the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300. For example, the path of the sound generated by the vibration generating module 400 can be a fifth sound path SP5. For example, the path of the sound generated by the first sound generating device 410 and the second sound generating device 430 can be a fifth sound path SP5. For example, the fifth sound path SP5 can be the forward direction (or the thickness direction of the display module) and the lateral direction of sound reflected by the rear surface of the display module 100. For example, the fifth sound path SP5 can be the direction in which sound from the vibration generating module 400 is reflected by the side surface of the structure 900 and output in the forward direction of the display module 100. For example, the fifth sound path SP5 can be the forward direction and the lateral direction of sound reflected from the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300, and can also be the forward direction and the lateral direction of sound output through the second connecting member 800. For example, the fifth sound path SP5 can be the direction in which sound from the first sound generating device 410 and the second sound generating device 430 is reflected by the side surface of the structure 900 and output in the forward direction of the display module 100. For example, the fifth sound path SP5 can be the forward direction and the lateral direction of sound reflected from the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300. Therefore, the sound generated by the vibration generating module 400 can be output through the fourth sound path SP4 and the fifth sound path SP5, thereby providing a display device for further enhancing the sound of the high-pitched vocal cords. For example, sound can be output by the first sound generating device 410 and the second sound generating device 430 through or via the fourth sound path SP4 and the fifth sound path SP5, thereby providing a display device for further enhancing the sound of the high-pitched vocal cords.

[0205] As mentioned above Figure 9The vibration generating module 400 can be configured to be tilted relative to the rear surface of the rear cover 300. For example, the first sound generating device 410 and the second sound generating device 430 can be configured to be tilted relative to the rear surface of the rear cover 300. For example, the sound from the vibration generating module 400 can be reflected between the vibration generating module 400 and the rear surface of the rear cover 300, and can be output in the forward direction of the display module 100 through at least one second hole 420. For example, the sound from the first sound generating device 410 and the second sound generating device 430 can be reflected between the first sound generating device 410 and the second sound generating device 430 and the rear surface of the rear cover 300, and can be output in the forward direction of the display module 100 through or via at least one second hole 420. Therefore, because a connecting member with one side or one side surface being open is provided, the sound from the vibration generating module 400 can be output in the lateral direction, and the area where the sound is reflected between the rear cover 300 and the vibration generating module 400 can be increased by tilting the vibration generating module 400, thereby enhancing the sound characteristics of the high-pitched vocal cords of the vibration generating module 400. Therefore, the area where sound is reflected between the back cover 300 and the vibration generating module 400 can be increased by the tilting generating module 400. Sound can be reflected from the side surface of the structure 900 and output in the forward direction of the display module 100, thereby further enhancing the sound characteristics of the high-pitched vocal bands and enhancing the sound of the low-pitched vocal bands. For example, the area where sound is reflected by the back cover 300 may increase the area where sound is reflected in each of the first sound generating device 410 and the second sound generating device 430. This sound can be output in the forward direction of the display module 100 through the second hole 420, and the sound can be reflected from the side surface of the structure 900 and output in the forward direction of the display module 100, thereby further enhancing the sound characteristics of the high-pitched vocal bands and enhancing the sound of the low-pitched vocal bands.

[0206] Figure 13 A display device according to another embodiment of the present disclosure is illustrated. Figure 14 A display device according to another embodiment of the present disclosure is illustrated. Figure 13 and Figure 14 Examples are shown by modifying Figure 12 Another embodiment of this disclosure is implemented by means of the structure of the back cover in the illustrated display device. Therefore, the back cover will be described in detail below, and other components will be derived from... Figure 12 The same reference numerals refer to the same items, and their repeated descriptions are omitted or will be given briefly.

[0207] refer to Figure 13 and Figure 14The rear cover 300 can be configured to be tilted relative to the vibration generating module 400. For example, the rear cover 300 can be configured to be tilted relative to the first sound generating device 410 and the second sound generating device 430. For example, the rear cover 300 may include at least one hole 420, and the at least one hole 420 may vary or change towards the center of the rear cover 300.

[0208] For example, including Figure 13 The rear cover 300 with at least one hole 420 can be formed by press forming or press molding, but the embodiments of this disclosure are not limited thereto. For example, it can be formed by a patterning process or a stamping process performed on the rear cover 300. Figure 14 At least one pattern 420, but the embodiments of this disclosure are not limited thereto. Figure 14 At least one hole 420 may be at least one pattern. For example, at least one hole or pattern 420 may be formed by patterning, chemical etching or drilling of the back cover 300 or by numerical control (NC) processing (e.g., processing performed by a CNC machine tool) or laser processing performed on the back cover 300, but embodiments of the present disclosure are not limited thereto.

[0209] For example, at least one hole or pattern 420 can be implemented to enhance the sound output at a side surface of the display module 100. For example, at least one hole or pattern 420 can have a height that gradually decreases from one side (or portion) to another side (or portion) opposite to one side (or portion). For example, at least one hole or structural pattern 420 can vary or change towards the center of the rear cover 300. For example, at least one hole or pattern 420 can vary from one side (or portion) of the display module 100 to another side (or portion). For example, at least one hole or pattern 420 overlapping with the vibration generating module 400 can vary from one side (or portion) of the display module 100 to another side (or portion). For example, at least one hole or pattern 420 overlapping with the first sound generating device 410 can vary from one side (or portion) of the display module 100 to another side (or portion). At least one hole or pattern 420 overlapping with the second sound generating device 430 can vary from another side (or portion) of the display module 100 to one side (or portion).

[0210] For example, the tilt angle of the back cover 300 can vary from one side (or part) of the display module 100 to the other side (or part), thereby enhancing the sound output at the side surface of the display module 100. For example, when the side where the second connecting member 800 is disposed is one side (or part) of the display module 100, the tilt angle of the back cover 300 can increase from one side (or part) of the display module 100 to the other side (or part). Therefore, the sound of the vibration generating module 400 can be effectively output at the other side of the second connecting member 800, where one side (or part) is open. For example, the sounds of the first sound generating device 410 and the second sound generating device 430 can be effectively output at the other side (or part) of the second connecting member 800, where one side (or part) is open. For example, the sound of the vibration generating module 400 can be reflected between the vibration generating module 400 and the rear surface of the back cover 300, and can be output in the forward direction of the display module 100, and can be reflected by the side surface of the structure 900 and can be output in the forward direction of the display module 100. For example, the sound from the first sound generating device 410 and the second sound generating device 430 can be reflected between the first sound generating device 410 and the second sound generating device 430 and the rear surface of the rear cover 300 and can be output in the forward direction of the display module 100, and can be reflected by the side surface of the structure 900 and can be output in the forward direction of the display module 100.

[0211] For example, at least one second hole 420 can enhance the sound reflection characteristics between the back cover 300 and the vibration generating module 400, thereby enhancing the sound of the high-pitched vocal cords. For example, at least one second hole 420 can enhance the sound reflection characteristics between the back cover 300 and the first sound generating device 410 and the second sound generating device 430, thereby enhancing the sound of the high-pitched vocal cords. For example, a back cover 300 including at least one second hole 420 and a connecting member 800 with one side (or part) open can include a sound guiding structure for guiding the sound of the vibration generating module 400 to be output in the forward or lateral direction of the display module 100. For example, a back cover 300 including at least one second hole 420 and a connecting member 800 with one side (or part) or one side surface open can include a sound guiding structure for guiding the sound of the first sound generating device 410 and the second sound generating device 430 to be output in the forward or lateral direction of the display module 100. For example, the rear cover 300 and / or structure 900, including at least one second hole 420 and a connecting member 800 with one side (or part) or one side surface open, may include a sound guiding structure that guides the sound of the vibration generating module 400 to be output in the forward or lateral direction of the display module 100. For example, the rear cover 300 and / or structure 900, including at least one second hole 420 and a connecting member 800 with one side (or part) or one side surface open, may include a sound guiding structure that guides the sound of the first sound generating device 410 and the second sound generating device 430 to be output in the forward or lateral direction of the display module 100.

[0212] refer to Figure 13The sound generated by the vibration generating module 400 can be reflected by the rear surface of the display module 100 and can be output in the lateral and forward directions of the display module 100. For example, the sound generated by the first sound generating device 410 and the second sound generating device 430 can be reflected by the rear surface of the display module 100 and can be output in the lateral and forward directions of the display module 100. For example, the path of the sound generated by the vibration generating module 400 can be a sixth sound path SP6. For example, the path of the sound generated by the first sound generating device 410 and the second sound generating device 430 can be a sixth sound path SP6. For example, the sixth sound path SP6 can be the direction in which the sound from the vibration generating module 400 is reflected by the side surface of the structure 900 and output in the forward direction of the display module 100. For example, the sixth sound path SP6 can be the direction in which the sound from the first sound generating device 410 and the second sound generating device 430 is reflected by the side surface of the structure 900 and output in the forward direction of the display module 100. For example, the sixth sound path SP6 can be the positive and lateral directions of sound reflected from the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300, and can be the positive and lateral directions of sound output through or via the second connecting member 800. For example, the sixth sound path SP6 can be the positive and lateral directions of sound reflected from the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300.

[0213] Sound from the vibration generating module 400 can be output in the forward direction of the display module 100 through or via the second hole 420. For example, sound from the first sound generating device 410 and the second sound generating device 430 can be output in the forward direction of the display module 100 through or via the second hole 420. For example, the path of sound generated by the vibration generating module 400 through or via the second hole 420 can be a seventh sound path SP7. For example, the path of each of the sounds generated by the first sound generating device 410 and the second sound generating device 430 through or via the second hole 420 can be the seventh sound path SP7. For example, the seventh sound path SP7 can be the forward direction in which sound is output from the rear surface of the display module 100 through or via the second hole 420 (or the thickness direction of the display module). For example, the seventh sound path SP7 can be the forward direction in which sound is output through or via the second hole 420 in the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300. Therefore, the sound generated by the vibration generation module 400 can be output through or via the sixth sound path SP6 and the seventh sound path SP7, thereby providing a display device for further enhancing the sound of the high-pitched vocal cords.

[0214] Therefore, the area where sound is reflected between the rear cover 300 and the vibration generating module 400 can be increased by including the second hole 420, thereby enhancing the sound of the high-pitched vocal cords. For example, since a connecting member with one side (or part) or one side surface open is provided, the sound of the vibration generating module 400 can be output in the lateral direction, and the area where sound is reflected between the rear cover 300 and the vibration generating module 400 can be increased by including the second hole 420. Therefore, the area where sound is reflected by the vibration generating module 400 can be increased due to the sound reflected by the rear cover 300, and the sound can be output in the forward direction of the display module 100 through the second hole 420, thereby providing a display device for enhancing the sound of the high-pitched vocal cords. For example, the area where the sound of each of the first sound generating device 410 and the second sound generating device 430 is reflected can be increased due to the sound reflected by the back cover 300. The sound can be output in the forward direction of the display module 100 through or via the second hole 420, and the sound can be reflected by the side surface of the structure 900 and can be output in the forward direction of the display module 100, thereby providing a display device for enhancing the sound of the high-pitched vocal cords.

[0215] refer to Figure 14 The sound generated by the vibration generating module 400 can be reflected by the rear surface of the display module 100 and can be output in the lateral and forward directions of the display module 100. For example, the sound generated by the first sound generating device 410 and the second sound generating device 430 can be reflected by the rear surface of the display module 100 and can be output in the lateral and forward directions of the display module 100. For example, the path of the sound generated by the vibration generating module 400 can be an eighth sound path SP8. For example, the path of the sound generated by the first sound generating device 410 and the second sound generating device 430 can be an eighth sound path SP8. For example, the eighth sound path SP8 can be the direction in which the sound from the vibration generating module 400 is reflected by the side surface of the structure 900 and output in the forward direction of the display module 100. For example, the eighth sound path SP8 can be the direction in which the sound from the first sound generating device 410 and the second sound generating device 430 is reflected by the side surface of the structure 900 and output in the forward direction of the display module 100. For example, the eighth sound path SP8 can be the positive and lateral directions of sound reflected from the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300, and can be the positive and lateral directions of sound output through or via the second connecting member 800. For example, the eighth sound path SP8 can be the positive and lateral directions of sound reflected from the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300.

[0216] The sound from the vibration generating module 400 can be output in the positive direction of the display module 100 via the second pattern 420. For example, the sound from the first sound generating device 410 and the second sound generating device 430 can be output in the positive direction of the display module 100 via the second pattern 420. For example, the path of the sound generated by the vibration generating module 400 through or via the second pattern 420 can be a ninth sound path SP9. For example, the path of the sound generated by the first sound generating device 410 and the second sound generating device 430 through or via the second pattern 420 can be a ninth sound path SP9. For example, the ninth sound path SP9 can be the positive direction of sound output from the rear surface of the display module 100 through or via the second pattern 420 (or the thickness direction of the display module). For example, the ninth sound path SP9 can be the positive direction of sound output from or via the second pattern 420 in the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300. Therefore, the sound from the vibration generation module 400 can be output through or via the eighth sound path SP8 and the ninth sound path SP9, thereby providing a display device for further enhancing the sound of the high-pitched vocal cords.

[0217] Therefore, the area where sound is reflected between the back cover 300 and the vibration generating module 400 can be increased by including the second pattern 420 on the back cover 300, thereby enhancing the sound of the high-pitched vocal cords. For example, since a connecting member with one side or one side surface open is provided, the sound of the vibration generating module 400 can be output in the lateral direction, and the area where sound is reflected between the back cover 300 and the vibration generating module 400 can be increased by including the second pattern 420 on the back cover 300. Therefore, the area where sound is reflected by the vibration generating module 400 can be increased due to the sound reflected by the back cover 300, and this sound can be output in the forward direction of the display module 100 via or through the second pattern 420, thereby providing a display device for enhancing the sound of the high-pitched vocal cords. For example, the area where the sound of each of the first sound generating device 410 and the second sound generating device 430 is reflected can be increased due to the sound reflected by the back cover 300. The sound can be output in the forward direction of the display module 100 through the second pattern 420, and the sound can be fed back from the side surface of the structure 900 and can be output in the forward direction of the display module 100, thereby providing a display device for enhancing the sound of the high-pitched vocal cords.

[0218] Despite Figure 13 and Figure 14While structure 900 is not provided, the area for reflecting sound from the vibration generating module 400 can be increased by tilting the rear cover 300 and / or by providing a second hole or pattern 420 in the rear cover 300. Sound can be output in the forward direction of the display module 100 via or through the second hole or pattern 420, thereby providing a display device for enhancing the sound of the high-pitched vocal cords. For example, the sound from the vibration generating module 400 can be reflected by the tilted rear cover 300 to increase the sound diffracted in the high-pitched vocal cords, and this sound can propagate in the forward direction of the display module 100, thereby providing a display device for enhancing the sound of the high-pitched vocal cords.

[0219] Figure 15 A display device according to another embodiment of the present disclosure is illustrated. Figure 15 By modifying Figure 9 The embodiments of this disclosure are implemented by the structure of the illustrated back cover. Therefore, the back cover will be described in detail below, and other components will be described in conjunction with... Figure 9 The same reference numerals refer to the same items, and their repeated descriptions are omitted or will be given briefly.

[0220] refer to Figure 15 The vibration generating module 400 can be configured to be inclined relative to the rear surface of the rear cover 300. For example, the vibration generating module 400 can be configured to be inclined via a second connecting member 800 that is open on one side (or part). For example, the vibration generating module 400 can be inclined at the height of the second connecting member 800. For example, the second connecting member 800 can have a height that gradually decreases from one side (or part) to another side (or part) opposite to the first side (or part). For example, the second connecting member 800 can include a first side parallel to one side (or part), a second side connected to one end (or part) of the first side, and a third side connected to another end (or part) of the first side that is parallel to the second side, and the height of the second and third sides can be lower when closer to the first side (thickness).

[0221] For example, the tilt angle of the vibration generating module 400 can vary from one side (or part) of the rear cover 300 to the other side (or part) of the rear cover 300, thereby amplifying the sound output at the side surface of the display module 100. For example, when the side where the second connecting member 800 is located is one side (or part) of the rear cover 300, the tilt angle of the vibration generating module 400 can increase from one side (or part) of the rear cover 300 to the other side (or part) of the rear cover 300. For example, the tilt angle of the vibration generating module 400 can increase from the central portion of the rear cover 300 to its side surface (or sidewall). Therefore, the sound from the vibration generating module 400 can be effectively output at the other side (or part) of the second connecting member 800, where one side (or part) is open.

[0222] According to another embodiment of this disclosure, the rear cover 300 can be disposed in a region other than the magnetic field region M corresponding to the magnetic member 403 of the vibration generating module 400. For example, the rear cover 300 can be disposed in a region other than the magnetic field region M corresponding to the magnetic member 403 of the first sound generating device 410 and the second sound generating device 430. For example, the portion other than the magnetic field region M can be the second hole 420 of the rear cover 300. The rear cover 300 can include an electroplated steel sheet (e.g., electrolytically galvanized steel sheet (EGI) or an iron (Fe) based material). For example, the electroplated steel sheet can be formed by electroplating zinc (Zn). Therefore, the rear cover 300 can be disposed in a region other than the magnetic field region M of the vibration generating module 400, thereby reducing the influence of the magnetic field caused by the rear cover 300 on the vibration generating module 400 and enhancing the sound characteristics of the vibration generating module 400. For example, the rear cover 300 can be disposed in a region other than the magnetic field region M of each of the first sound generating device 410 and the second sound generating device 430. Therefore, the influence of the magnetic field caused by the back cover 300 on the first sound generating device 410 and the second sound generating device 430 can be reduced, thereby enhancing the sound characteristics of the first sound generating device 410 and the second sound generating device 430.

[0223] For example, a rear cover 300 including at least one second hole 420 and a connecting member 800 with one side (or part) or one side surface open may include a sound guiding structure that guides the sound of the vibration generating module 400 to be output in the forward or lateral direction of the display module 100. For example, a rear cover 300 including at least one second hole 420 may include a sound guiding structure that guides the sound of the vibration generating module 400 to be output in the forward or lateral direction of the display module 100. For example, a rear cover 300 including at least one second hole 420 may include a sound guiding structure that guides the sound of the first sound generating device 410 and the second sound generating device 430 to be output in the forward or lateral direction of the display module 100. For example, a rear cover 300 and / or structure 900 including at least one second hole 420 and a connecting member 800 with one side (or part) or one side surface open may include a sound guiding structure that guides the sound of the vibration generating module 400 to be output in the forward or lateral direction of the display module 100. For example, the back cover 300, including at least one second hole 420 and / or structure 900, may include a sound guiding structure that guides the sound of the vibration generating module 400 to be output in the forward or lateral direction of the display module 100. For example, the back cover 300, including at least one second hole 420 and / or structure 900, may include a sound guiding structure that guides the sound of the first sound generating device 410 and the second sound generating device 430 to be output in the forward or lateral direction of the display module 100.

[0224] For example, the sound from the vibration generating module 400 can be reflected between the vibration generating module 400 and the rear surface of the rear cover 300, and can be output in the forward direction of the display module 100. For example, the sound from the first sound generating device 410 and the second sound generating device 430 can be reflected between the first sound generating device 410 and the second sound generating device 430 and the rear surface of the rear cover 300, and can be output in the forward direction of the display module 100. For example, the sound from the vibration generating module 400 can be reflected between the vibration generating module 400 and the rear surface of the rear cover 300 corresponding to the magnetic field region M, and can be output in the forward direction of the display module 100. For example, the sound from the first sound generating device 410 and the second sound generating device 430 can be reflected between the vibration generating module 400 and the rear surface of the rear cover 300 corresponding to the magnetic field region M, and can be output in the forward direction of the display module 100. For example, the sound from the first sound generating device 410 and the second sound generating device 430 can be reflected by the side surface of the structure 900, and can be output in the forward direction of the display module 100. For example, because a connecting member 800 with one side (or part) or one side surface open is provided, the sound of the vibration generating module 400 can be output in the lateral direction, thereby enhancing the sound of the high-pitched vocal cords. For example, because a connecting member 800 with one side (or part) or one side surface open is provided, the sound of the vibration generating module 400 can be output in the lateral direction, and the area where sound is reflected between the rear cover 300 and the vibration generating module 400 can be increased by tilting the vibration generating module 400, thereby enhancing the sound of the high-pitched vocal cords. Therefore, the area where sound is reflected by the vibration generating module 400 can be increased due to the sound reflected by the rear cover 300, the sound can be reflected by the side surface of the structure 900 and output in the forward direction of the display module 100, and the sound can be reflected from the magnetic field region M and output in the forward direction of the display module 100, thereby further enhancing the sound of the high-pitched vocal cords. For example, the area where the sound of the first sound generating device 410 and the second sound generating device 430 is reflected can be increased due to the sound reflected by the back cover 300. The sound can be reflected by the side surface of the structure 900 and can be output in the positive direction of the display module 100. The sound can also be reflected from the magnetic field region M and can be output in the positive direction of the display module 100, thereby further enhancing the sound of the high-pitched vocal cords.

[0225] For example, the path of sound generated by vibration generating module 400 can be a tenth sound path SP10. For example, the path of sound generated by first sound generating device 410 and second sound generating device 430 can be a tenth sound path SP10. For example, the tenth sound path SP10 can be the forward direction (or the thickness direction of the display module) and the lateral direction of sound reflected from the rear surface of display module 100. For example, the tenth sound path SP10 can be the forward direction and the lateral direction of sound reflected from the gap space GS (or sound output space) between vibration generating module 400 and rear cover 300, and can be the forward direction of sound reflected from the rear surface of structure 900. For example, the tenth sound path SP10 can be the forward direction and the lateral direction of sound reflected from the gap space GS (or sound output space) between vibration generating module 400 and rear cover 300, and can be the forward direction and the lateral direction of sound output through or via second connecting member 800. For example, the tenth sound path SP10 can be the lateral and forward direction of sound reflected from the magnetic field region M and / or the second hole 420, and can be the forward direction of sound reflected by the structure 900.

[0226] For example, sound from the vibration generating module 400 can be output in the positive direction of the display module 100 through or via the second hole 420. For example, sound from the first sound generating device 410 and the second sound generating device 430 can be output in the positive direction of the display module 100 through or via the second hole 420. For example, the path of sound generated by the vibration generating module 400 through or via the second hole 420 can be an eleventh sound path SP11. For example, the path of sound generated by the first sound generating device 410 and the second sound generating device 430 through the second hole 420 can be an eleventh sound path SP11. For example, the eleventh sound path SP11 can be the positive direction (or the thickness direction of the display module) in which sound is output from the rear surface of the display module 100 through the second hole 420 and / or the magnetic field region M. For example, the eleventh sound path SP11 can be the positive direction in which sound is output in the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300. Therefore, the sound from the vibration generation module 400 can be output through or via the tenth sound path SP10 and the eleventh sound path SP11, thereby providing a display device for further enhancing the sound of the high-pitched vocal cords.

[0227] Despite Figure 15While structure 900 is not provided, the area where sound from vibration generation module 400 is reflected can be increased by a structure comprising tilted vibration generation module 400 and / or second hole 420 disposed in rear cover 300. Sound can then be output in the forward direction of display module 100 through second hole 420, thereby providing a display device for enhancing the sound of high-pitched vocal cords. For example, sound from vibration generation module 400 can be reflected by tilted vibration generation module 400 to increase the sound diffracted in high-pitched vocal cords, and this sound can propagate in the forward direction of display module 100, thereby providing a display device for enhancing the sound of high-pitched vocal cords.

[0228] Figure 16 A display device according to another embodiment of the present disclosure is illustrated. Figure 16 Examples are shown by modifying Figure 9 and Figure 15 The embodiments of this disclosure are implemented by means of the structure of the back cover in the illustrated display device. Therefore, the back cover will be described in detail below, and other components will be described in terms of their relationship with the back cover. Figure 9 and Figure 15 The same reference numerals refer to the same items, and their repeated descriptions are omitted or will be given briefly.

[0229] refer to Figure 16 The vibration generating module 400 can be configured to be inclined relative to the rear surface of the rear cover 300. For example, the vibration generating module 400 can be configured to be inclined by a second connecting member 800 with one side (or part) open. For example, the vibration generating module 400 can be inclined at the height of the second connecting member 800. For example, the second connecting member 800 can have a height that gradually decreases from one side (or part) to another side (or part) opposite to one side (or part). For example, the second connecting member 800 can include a first side parallel to one side (or part), a second side connected to one end (or part) of the first side, and a third side connected to another end (or part) of the first side parallel to the second side, and each of the second and third sides can have a lower height (thickness) closer to the first side.

[0230] For example, the tilt angle of the vibration generating module 400 can vary from one side (or part) of the rear cover 300 to the other side (or part) of the rear cover 300, thereby amplifying the sound output at the side surface of the display module 100. For example, when the side where the second connecting member 800 is located is one side (or part) of the rear cover 300, the tilt angle of the vibration generating module 400 can increase from one side (or part) of the rear cover 300 to the other side of the rear cover 300. For example, the tilt angle of the vibration generating module 400 can increase from the central portion of the rear cover 300 to its side (or sidewall). Therefore, the sound from the vibration generating module 400 can be effectively output at the other side of the second connecting member 800, where one side (or part) is open.

[0231] According to another embodiment of this disclosure, the back cover 300 can be disposed in the magnetic field region M corresponding to the magnet component 403 of the vibration generating module 400 and on the rear surface of the display module 100. For example, the back cover 300 can be disposed in the magnetic field region M corresponding to the magnet component 403 of each of the first sound generating device 410 and the second sound generating device 430 and on the rear surface of the display module 100. For example, the second hole 420 can be disposed between the portion other than the magnetic field region M and the back cover 300. For example, the back cover 300 can include materials other than the iron (Fe)-based material included in the magnet component. For example, the back cover 300 can include one or more of Al material, Mg alloy material, Mg-Li alloy material and Al alloy material. However, the embodiments of this disclosure are not limited thereto, and the back cover 300 can be formed of a material that does not have an iron (Fe) material. Therefore, the back cover 300 can be disposed in the magnetic field region M, and a back cover 300 including the second hole 420 can be implemented. For example, the influence of the magnetic field caused by the back cover 300 on the first sound generating device 410 and the second sound generating device 430 can be reduced, and the sound characteristics of the first sound generating device 410 and the second sound generating device 430 can be enhanced.

[0232] For example, a rear cover 300 including at least one second hole 420 and a connecting member 800 with one side (or part) or one side surface open may include a sound guiding structure that guides the sound of the vibration generating module 400 to be output in the forward or lateral direction of the display module 100. For example, a rear cover 300 including at least one second hole 420 may include a sound guiding structure that guides the sound of the vibration generating module 400 to be output in the forward or lateral direction of the display module 100. For example, a rear cover 300 including at least one second hole 420 may include a sound guiding structure that guides the sound of the first sound generating device 410 and the second sound generating device 430 to be output in the forward or lateral direction of the display module 100. For example, a rear cover 300 and / or structure 900 including at least one second hole 420 and a connecting member 800 with one side (or part) or one side surface open may include a sound guiding structure that guides the sound of the vibration generating module 400 to be output in the forward or lateral direction of the display module 100. For example, the back cover 300, including at least one second hole 420 and / or structure 900, may include a sound guiding structure that guides the sound of the vibration generating module 400 to be output in the forward or lateral direction of the display module 100. For example, the back cover 300, including at least one second hole 420 and / or structure 900, may include a sound guiding structure that guides the sound of the first sound generating device 410 and the second sound generating device 430 to be output in the forward or lateral direction of the display module 100.

[0233] For example, the sound from the vibration generating module 400 can be reflected between the vibration generating module 400 and the rear surface of the rear cover 300, and can be output in the forward direction of the display module 100. For example, the sound from the first sound generating device 410 and the second sound generating device 430 can be reflected between the first sound generating device 410 and the second sound generating device 430 and the rear surface of the rear cover 300, and can be output in the forward direction of the display module 100. For example, the sound from the vibration generating module 400 can be reflected between the vibration generating module 400 and the rear surface of the rear cover 300 corresponding to the magnetic field region M, and can be output in the forward direction of the display module 100. For example, the sound from the first sound generating device 410 and the second sound generating device 430 can be reflected between the vibration generating module 400 and the rear surface of the rear cover 300 corresponding to the magnetic field region M, and can be output in the forward direction of the display module 100. For example, the sound from the vibration generating module 400 can be reflected by the side surface of the structure 900, and can be output in the forward direction of the display module 100. For example, the sound from the first sound generating device 410 and the second sound generating device 430 can be reflected by the side surface of the structure 900 and can be output in the forward direction of the display module 100. Therefore, since a connecting member 800 with one side (or part) or one side surface open is provided, the sound from the vibration generating module 400 can be output in the lateral direction, thereby enhancing the sound of the high-pitched vocal cords. For example, since a connecting member 800 with one side (or part) or one side surface open is provided, the sound from the vibration generating module 400 can be output in the lateral direction, and the area where sound is reflected between the rear cover 300 and the vibration generating module 400 can be increased by tilting the vibration generating module 400, thereby enhancing the sound of the high-pitched vocal cords. Therefore, the area where sound is reflected by the vibration generating module 400 can be increased due to the sound reflected by the rear cover 300, the sound can be reflected by the side surface of the structure 900 and output in the forward direction of the display module 100, and the sound can be reflected from the magnetic field region M and output in the forward direction of the display module 100, thereby further enhancing the sound of the high-pitched vocal cords. For example, the area where the sound of the first sound generating device 410 and the second sound generating device 430 is reflected can be increased due to the sound reflected by the back cover 300. The sound can be reflected by the side surface of the structure 900 and can be output in the positive direction of the display module 100. The sound can also be reflected from the magnetic field region M and can be output in the positive direction of the display module 100, thereby further enhancing the sound of the high-pitched vocal cords.

[0234] For example, the sound path generated by the vibration generating module 400 can be the twelfth sound path SP12. For example, the sound path generated by the first sound generating device 410 and the second sound generating device 430 can be the twelfth sound path SP12. For example, the twelfth sound path SP12 can be the forward direction (or the thickness direction of the display module) and the lateral direction of sound reflected from the rear surface of the display module 100. For example, the twelfth sound path SP12 can be the forward direction and the lateral direction of sound reflected from the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300, and can be the forward direction of sound reflected from the side surface of the structure 900. For example, the twelfth sound path SP12 can be the forward direction and the lateral direction of sound reflected from the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300, and can be the forward direction and the lateral direction of sound output through or via the second connecting member 800. For example, the twelfth sound path SP12 can be the lateral and forward directions of sound reflected from the magnetic field region M and / or the second hole 420, and can be the forward direction of sound reflected by the structure 900.

[0235] Sound from the vibration generating module 400 can be output in the positive direction of the display module 100 through the second hole 420. For example, sound from the first sound generating device 410 and the second sound generating device 430 can be output in the positive direction of the display module 100 through the second hole 420. For example, the path of sound generated by the vibration generating module 400 through or via the second hole 420 can be a thirteenth sound path SP13. For example, the path of each of the sounds generated by the first sound generating device 410 and the second sound generating device 430 through or via the second hole 420 can be a thirteenth sound path SP13. For example, the thirteenth sound path SP13 can be the positive direction (or the thickness direction of the display module) in which sound is output from the rear surface of the display module 100 through the second hole 420 and / or the magnetic field region M. For example, the thirteenth sound path SP13 can be the positive direction in which sound is output in the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300. Therefore, the sound from the vibration generation module 400 can be output through the twelfth sound path SP12 and the thirteenth sound path SP13, thereby providing a display device for further enhancing the sound of the high-pitched vocal cords.

[0236] Despite Figure 16While structure 900 is not explicitly provided, the area where sound from vibration generation module 400 is reflected can be increased by tilting the structure or magnetic field region M of the second hole 420 and / or the rear cover 300 of the magnetic field region M. This allows the sound reflected from the second hole, pattern 420, or magnetic field region M to be output to the forward direction of display module 100, thereby providing a display device for enhancing the sound of high-pitched vocal bands. For example, the sound from vibration generation module 400 can be reflected by tilting vibration generation module 400 to increase the sound diffracted in high-pitched vocal bands, and this sound can propagate in the forward direction of display module 100, thus providing a display device for enhancing the sound of high-pitched vocal bands.

[0237] Figure 17 A display device according to another embodiment of the present disclosure is illustrated. Figure 18 A display device according to another embodiment of the present disclosure is illustrated. Figure 17 and Figure 18 Examples are shown by modifying Figure 9 and Figure 15 The embodiments of this disclosure are implemented by means of the structure of the back cover in the illustrated display device. Therefore, the back cover will be described in detail below, and other components will be described in terms of their relationship with the back cover. Figure 9 and Figure 15 The same reference numerals refer to the same items, and their repeated descriptions are omitted or will be given briefly.

[0238] refer to Figure 17 and Figure 18 The vibration generating module 400 can be configured to be inclined relative to the rear surface of the rear cover 300. For example, the vibration generating module 400 can be configured to be inclined via a second connecting member 800 that is open on one side (or part). For example, the vibration generating module 400 can be inclined at the height of the second connecting member 800. For example, the second connecting member 800 can have a height that gradually decreases from one side (or part) to another side (or part) opposite to one side (or part). For example, the second connecting member 800 can include a first side parallel to one side (or part), a second side connected to one end (or part) of the first side, and a third side connected to another end (or part) of the first side that is parallel to the second side, and each of the second and third sides can have a lower height (thickness) closer to the first side.

[0239] For example, the tilt angle of the vibration generating module 400 can vary from one side (or part) of the rear cover 300 to the other side (or part) of the rear cover 300, thereby amplifying the sound output at the side surface of the display module 100. For example, when one side of the rear cover 300 is where the second connecting member 800 is located, the tilt angle of the vibration generating module 400 can increase from one side (or part) of the rear cover 300 to the other side (or part). For example, the tilt angle of the vibration generating module 400 can increase from the central portion of the rear cover 300 to its side (or sidewall). Therefore, the sound from the vibration generating module 400 can be effectively output at the other side (or part) of the second connecting member 800, where one side (or part) is open.

[0240] According to another embodiment of this disclosure, the rear cover 300 can be disposed in a region other than the magnetic field region M corresponding to the magnetic component 403 of the vibration generating module 400. For example, the rear cover 300 can be disposed in a region other than the magnetic field region M corresponding to the magnetic component 403 of each of the first sound generating device 410 and the second sound generating device 430. For example, the portion other than the magnetic field region M can be the second hole 420 of the rear cover 300. The rear cover 300 can include an electrolytic steel sheet (e.g., electrolytic galvanized steel sheet (EGI) or an iron (Fe) based material). For example, the electrolytic steel sheet can be formed by electroplating zinc (Zn). Therefore, the rear cover 300 can be disposed in a region other than the magnetic field region M of the vibration generating module 400, thereby reducing the influence of the magnetic field caused by the rear cover 300 on the vibration generating module 400 and enhancing the sound characteristics of the vibration generating module 400.

[0241] According to another embodiment of this disclosure, a second rear cover 320 disposed on the rear surface of the rear cover 300 may be provided. For example, the second rear cover 320 may be disposed between the rear cover 300 and the vibration generating module 400. For example, the second rear cover 320 may be disposed between the rear cover 300 and the first sound generating device 410 and the second sound generating device 430. For example, the second rear cover 320 may overlap a portion of the rear cover 300. For example, the second rear cover 320 may be disposed in a magnetic field region M corresponding to the magnetic member 403 of the vibration generating module 400. For example, the second rear cover 320 may be disposed in a magnetic field region M corresponding to the magnetic member 403 of each of the first sound generating device 410 and the second sound generating device 430.

[0242] For example, the second back cover 320 may include a non-ferrous metal to reduce the influence of the magnetic field induced by the back cover 300 on the vibration generating module 400. For example, the second back cover 320 may include a non-ferrous metal to reduce the influence of the magnetic field induced by the back cover 300 on the first sound generating device 410 and the second sound generating device 430. For example, the second back cover 320 may include a material other than the iron (Fe)-based material contained in the magnet member 403. For example, the second back cover 320 may include one of Al material, Mg alloy material, Mg-Li alloy material, and Al alloy material. However, embodiments of this disclosure are not limited thereto, and the second back cover 320 may be made of a material that does not contain iron (Fe). Therefore, the influence of the magnetic field induced by the back cover 300 on the vibration generating module 400 can be reduced, thus reducing the sound loss of the vibration generating module 400 and enhancing the sound characteristics of the vibration generating module 400. For example, the effect of the magnetic field caused by the back cover 300 on the first sound generating device 410 and the second sound generating device 430 can be reduced, and the sound characteristics of each of the first sound generating device 410 and the second sound generating device 430 can be enhanced.

[0243] For example, the back cover 300 may include at least one second hole 420. For example, the back cover 300 may include at least one second hole 420 overlapping with the second back cover 320. At least one second hole 420 may overlap with the back cover 300 and the second back cover 320.

[0244] The third connecting member 820 may be further disposed between the rear cover 300 and the second rear cover 320. The third connecting member 820 may be an adhesive. For example, the adhesive may be a single-sided adhesive, a single-sided foam adhesive, a single-sided tape, a single-sided foam tape, a double-sided adhesive, a double-sided foam adhesive, a double-sided tape, a double-sided foam tape, or a pressure-sensitive adhesive (PSA), but the embodiments of this disclosure are not limited thereto.

[0245] refer to Figure 17 The second rear cover 320 and the rear cover 300 can be disposed on the same plane. For example, the height and / or shape of the second rear cover 320 disposed near the second hole 420 can be adjusted to further enhance the sound reflected by the vibration generating module 400. For example, the height and / or shape of the second rear cover 320 disposed near the second hole 420 can be adjusted to further enhance the sound reflected by each of the first sound generating device 410 and the second sound generating device 430.

[0246] refer to Figure 18The second rear cover 320 can be disposed between the second holes 420 of the rear cover 300. For example, the second rear cover 320 can be disposed between the rear cover 300 and the vibration generating module 400. For example, the second rear cover 320 can be disposed between the rear cover 300 and the first sound generating device 410 and the second sound generating device 430. For example, the second rear cover 320 and / or the rear cover 300 can be implemented in a shaped form, thus simplifying the manufacturing process. The second hole 420 can be formed by forming a slit in the second rear cover 320. For example, since the second rear cover 320 and the rear cover 300 are formed in a shaped form, the area where the sound of the vibration generating module 400 is reflected can be further increased. For example, the height and / or shape of the second rear cover 320 disposed near the second hole 420 can be adjusted to further enhance the sound reflected by the vibration generating module 400.

[0247] For example, a connecting member 800 with one side (or part) or one side surface open, a rear cover 300 including at least one second hole 420, and / or a second rear cover 320 may include a sound guiding structure for guiding the sound of the first sound generating device 410 and the second sound generating device 430 to be output in the forward or lateral direction of the display module 100. For example, a rear cover 300 including at least one second hole 420 and / or a second rear cover 320 may include a sound guiding structure for guiding the sound of the first sound generating device 410 and the second sound generating device 430 to be output in the forward or lateral direction of the display module 100. For example, a rear cover 300 including at least one second hole 420 and / or a structure 900 including the second rear cover 320 may include a sound guiding structure for guiding the sound of the first sound generating device 410 and the second sound generating device 430 to be output in the forward or lateral direction of the display module 100. For example, a rear cover 300 including at least one second hole 420, a second rear cover 320, and / or a structure 900 may include a sound guiding structure that guides the sound of the first sound generating device 410 and the second sound generating device 430 to be output in the forward or lateral direction of the display module 100. For example, a connecting member 800 with one side (or part) or one side surface open, a rear cover 300 including at least one second hole 420, a second rear cover 320, and / or a structure 900 may include a sound guiding structure that guides the sound of the first sound generating device 410 and the second sound generating device 430 to be output in the forward or lateral direction of the display module 100.

[0248] For example, the sound from the vibration generating module 400 can be reflected between the vibration generating module 400 and the rear surface of the rear cover 300, and can be output in the forward direction of the display module 100. For example, the sound from the first sound generating device 410 and the second sound generating device 430 can be reflected between the first sound generating device 410 and the second sound generating device 430 and the rear surface of the rear cover 300, and can be output in the forward direction of the display module 100. For example, the sound from the vibration generating module 400 can be reflected between the vibration generating module 400 and the rear surface of the rear cover 300 corresponding to the magnetic field region M, and can be output in the forward direction of the display module 100. For example, the sound from the first sound generating device 410 and the second sound generating device 430 can be reflected between the vibration generating module 400 and the rear surface of the rear cover 300 corresponding to the magnetic field region M, and can be output in the forward direction of the display module 100. For example, the sound from the vibration generating module 400 can be reflected by the side surface of the structure 900, and can be output in the forward direction of the display module 100. For example, the sound from the first sound generating device 410 and the second sound generating device 430 can be reflected by the side surface of the structure 900 and can be output in the forward direction of the display module 100. Therefore, since a connecting member 800 with one side (or part) or one side surface open is provided, the sound from the vibration generating module 400 can be output in the lateral direction, thereby enhancing the sound of the high-pitched vocal cords. For example, since a connecting member 800 with one side (or part) or one side surface open is provided, the sound from the vibration generating module 400 can be output in the lateral direction, and the area where sound is reflected between the rear cover 300 and the vibration generating module 400 can be increased by tilting the vibration generating module 400, thereby enhancing the sound of the high-pitched vocal cords. Therefore, the area where sound is reflected by the vibration generating module 400 can be increased due to the sound reflected by the rear cover 300, the sound can be reflected by the side surface of the structure 900 and output in the forward direction of the display module 100, and the sound can be reflected from the magnetic field region M and output in the forward direction of the display module 100, thereby further enhancing the sound of the high-pitched vocal cords. For example, the area where the sound of the first sound generating device 410 and the second sound generating device 430 is reflected can be increased due to the sound reflected by the back cover 300. The sound can be reflected by the side surface of the structure 900 and can be output in the positive direction of the display module 100. The sound can also be reflected from the magnetic field region M and can be output in the positive direction of the display module 100, thereby further enhancing the sound of the high-pitched vocal cords.

[0249] refer to Figure 17The sound path generated by the vibration generating module 400 can be the fourteenth sound path SP14. For example, the sound path generated by the first sound generating device 410 and the second sound generating device 430 can be the fourteenth sound path SP14. For example, the fourteenth sound path SP14 can be the forward direction (or the thickness direction of the display module) and the lateral direction of sound reflected from the rear surface of the display module 100. For example, the fourteenth sound path SP14 can be the forward direction and the lateral direction of sound reflected from the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300, and it can be the forward direction of sound reflected from the side surface of the structure 900. For example, the fourteenth sound path SP14 can be the forward direction and the lateral direction of sound reflected from the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300, and it can be the forward direction and the lateral direction of sound output through the second connecting member 800. For example, the fourteenth sound path SP14 can be the positive direction of sound reflection from magnetic field region M and / or second hole 420, and can also be the positive direction of sound reflection from structure 900.

[0250] refer to Figure 17 The sound from the vibration generating module 400 can be output in the positive direction of the display module 100 through or via the second hole 420. For example, the sound from the first sound generating device 410 and the second sound generating device 430 can be output in the positive direction of the display module 100 through or via the second hole 420. For example, the path of the sound generated by the vibration generating module 400 through or via the second hole 420 can be the fifteenth sound path SP15. For example, the path of each sound generated by the first sound generating device 410 and the second sound generating device 430 through or via the second hole 420 can be the fifteenth sound path SP15. For example, the fifteenth sound path SP15 can be the positive direction (or the thickness direction of the display module) in which the sound is output from the rear surface of the display module 100 through or via the second hole 420 and / or the magnetic field region M. For example, the fifteenth sound path SP15 can be the positive direction in which the sound is output in the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300. Therefore, the sound generated by the vibration generation module 400 can be output through or via the fourteenth sound path SP14 and the fifteenth sound path SP15, thereby providing a display device for further enhancing the sound of the high-pitched vocal cords.

[0251] refer to Figure 18The sound path generated by the vibration generating module 400 can be the sixteenth sound path SP16. For example, the sound path generated by the first sound generating device 410 and the second sound generating device 430 can be the sixteenth sound path SP16. For example, the sixteenth sound path SP16 can be the positive direction (or the thickness direction of the display module) and the lateral direction of sound reflected from the rear surface of the display module 100. For example, the sixteenth sound path SP16 can be the positive direction and the lateral direction of sound reflected from the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300, and can be the positive direction of sound reflected from the side surface of the structure 900. For example, the sixteenth sound path SP16 can be the positive direction and the lateral direction of sound reflected from the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300, and can be the positive direction and the lateral direction of sound output through or via the second connecting member 800. For example, the sixteenth sound path SP16 can be the lateral and forward directions of sound reflected from the magnetic field region M and / or the second hole 420, and can be the forward direction of sound reflected by the structure 900.

[0252] refer to Figure 18 The sound from the vibration generating module 400 can be output in the positive direction of the display module 100 through or via the second hole 420. For example, the sound from the first sound generating device 410 and the second sound generating device 430 can be output in the positive direction of the display module 100 through or via the second hole 420. For example, the path of the sound generated by the vibration generating module 400 through or via the second hole 420 can be the seventeenth sound path SP17. For example, the path of the sound generated by the first sound generating device 410 and the second sound generating device 430 through or via the second hole 420 can be the seventeenth sound path SP17. For example, the seventeenth sound path SP17 can be the positive direction (or the thickness direction of the display module) in which the sound is output from the rear surface of the display module 100 through or via the second hole 420 and / or the magnetic field region M. For example, the seventeenth sound path SP17 can be the positive direction in which the sound is output in the gap space GS (or sound output space) between the vibration generating module 400 and the rear cover 300. Therefore, the sound of the vibration generation module 400 can be output through or via the sixteenth sound path SP16 and the seventeenth sound path SP17, thereby providing a display device for further enhancing the sound of the high-pitched vocal cords.

[0253] Despite Figure 17 and Figure 18While structure 900 is not provided, the area where sound from vibration generation module 400 is reflected can be increased by tilting vibration generation module 400 and / or rear cover 300 and / or second rear cover 320. Sound reflected from the second hole or pattern 420 or magnetic field region M can be output to the positive direction of display module 100, thereby providing a display device for enhancing the sound of high-pitched vocal bands. For example, sound from vibration generation module 400 can be reflected by tilting vibration generation module 400 to increase the sound diffracted in high-pitched vocal bands, and this sound can propagate in the positive direction of display module 100, thereby providing a display device for enhancing the sound of high-pitched vocal bands.

[0254] Figure 19 A display device according to another embodiment of the present disclosure is illustrated. Figure 20 It is along Figure 19 The cross-sectional view taken by line II-II' as illustrated in the figure. Figure 19 and Figure 20 Examples are shown by modifying Figures 1 to 18 The embodiments of this disclosure are implemented based on the structure of the back cover and backlight section of the display device illustrated herein. Therefore, the back cover and backlight section will be described in detail below, while other components will be described in detail based on the structure of the back cover and backlight section. Figures 1 to 18 The same reference numerals in the figures refer to the same things, and repeated descriptions of them are omitted or will be given briefly.

[0255] refer to Figure 19 and Figure 20 In another embodiment of the display device according to the present disclosure, the back cover 300 can support the backlight portion 130 of the display module 100, thereby providing an internal air gap 132 in the backlight portion 130.

[0256] According to an embodiment of the present disclosure, the rear cover 300 may include a rear portion 310 supporting the rear surface of the display module 100 and a side portion 330 connected to the periphery of the rear portion 310 to support the support member 200.

[0257] The rear portion 310 can be configured to cover the rear surface of the display module 100 and to support the display module 100. The rear portion 310 can support the backlight portion 130 of the display module 100 and can be configured to support the vibration generating module 400.

[0258] The rear portion 310 may include a cross-sectional structure with a concave curved shape, such that an internal air gap 132 is disposed in the backlight portion 130. The internal air gap 132 of the backlight portion 130 can serve as a speaker for sound generated and propagated based on the vibration of the first vibration generating module 400, thereby enhancing the sound characteristics of the bass vocal cords. Except for the cross-sectional structure with a concave curved shape, the rear portion 310 may be substantially the same as the rear portion described above; therefore, repeated descriptions of structures other than the cross-sectional structure with a concave curved shape are omitted.

[0259] According to embodiments of the present disclosure, the rear portion 310 may have a cup-shaped structure, wherein the central region MA of the display module 100 protrudes relative to the first direction X (or lateral direction) of the display module 100 onto the rear surface of the display device. For example, the distance (or interval) between the upper surface of the rear portion 310 and the rear surface of the display panel 110 may gradually increase relative to the first direction X (or lateral direction) of the display module 100 from the peripheral regions EA1 and EA2 to the central region MA.

[0260] In the rear portion 310 according to the embodiments of the present disclosure, the distance (or depth) between the middle region MA of the rear portion 310 and the virtual plane surface (or horizontal line) connecting one end and the other end of the rear portion 310 may be about 0.01% to 0.5% of the total length of the rear portion 310 relative to the first direction X (or lateral direction) of the display module 100.

[0261] For example, when the depth of the middle region MA of the rear portion 310 is approximately 0% of the total length of the rear portion 310, the rear portion 310 can have a generally planar structure; for example, the internal air gap 132 may not be provided in the backlight portion 130. Furthermore, when the depth of the middle region MA of the rear portion 310 is greater than approximately 0.5% of the total length of the rear portion 310, the distance (or size) of the internal air gap 132 of the backlight portion 130 may increase. Therefore, the loss of sound waves from the high-pitched vocal bands, which is proportional to the distance, may increase. Consequently, the sound from the mid-to-high-pitched vocal bands may not be realized or the sound waves from the mid-to-high-pitched vocal bands may be reduced. The sound from the mid-to-high-pitched vocal bands generated by the first vibration generating device 410 and the sound from the mid-to-low-pitched vocal bands generated by the second vibration generating device 430 may be separated from each other, and the thickness of the display device may increase. Therefore, the depth of the middle region MA of the rear portion 310 can be set to approximately 0.01% to 0.5% of the total length of the rear portion 310, such that the internal air gap 132 of the backlight portion 130 serves as a speaker enclosure for enhancing the sound characteristics of the low-pitched vocal bands. For example, the mid-pitched vocal bands can be from 200Hz to 3kHz, but embodiments of this disclosure are not limited thereto, and can be from 3kHz to 5kHz. The high-pitched vocal bands can be 3kHz or higher, but embodiments of this disclosure are not limited thereto, and can be 5kHz or higher.

[0262] The side portion 330 can be bent from the periphery of the rear portion 310 and can be configured to support the support member 200. The side portion 330 can provide a backlight receiving space in the rear portion 310 and can surround the side surface of the backlight portion 130 that is received in (or supported by) the backlight receiving space.

[0263] The backlight unit 130 may include a reflective sheet 133, a light guiding component 131, a light source component, and an optical sheet component 135.

[0264] A reflective sheet 133 may be disposed on the rear portion 310 of the rear cover 300. The reflective sheet 133 may be disposed on the rear portion 310 to have a concave shape along the concave shape of the rear portion 310. For example, the reflective sheet 133 may be bent into a concave shape by its own weight (or self-load), and thus may be disposed in the rear portion 310 to have a conformal shape based on the shape of the rear portion 310. The reflective sheet 133 may reflect light incident from the light guiding member 131 back to the light guiding member 131 to minimize or reduce light loss.

[0265] The light guiding component 131 may include a light incident surface disposed on the reflector 133 to overlap with the display panel 110 and disposed on at least one sidewall thereon. The light guiding component 131 may include a light-transmitting plastic or glass material. The light guiding component 131 may allow light incident from the light source component through the light incident surface to propagate to the display panel 110.

[0266] According to embodiments of the present disclosure, the light guiding member 131 can be disposed on the reflective sheet 133 in a concave shape not based on the concave shape of the rear portion 310. For example, the light guiding member 131 can be disposed on the reflective sheet 133 in a non-conformal shape not based on the shape of the reflective sheet 133 (or the rear portion 310). Therefore, the backlight portion 130 can include an internal air gap 132 between the reflective sheet 133 and the light guiding member 131. The internal air gap 132 can be provided between the light guiding member 131 and the reflective sheet 133 overlapping with the intermediate region MA of the display module 100. The reflective sheet 133 overlapping with the peripheral region EA of the display module 100 can contact the periphery of the light guiding member 131, therefore, the internal air gap 132 may not be provided between the reflective sheet 133 and the periphery of the light guiding member 131. The internal air gap 132 can be provided between the light guiding member 131 and the reflective sheet 133 overlapping with the intermediate region MA of the display module 100. Therefore, the internal air gap 132 can be used as a speaker for sound generated and propagated by vibration based on the vibration generation module 400, thereby enhancing the sound characteristics of the low-pitched vocal cords.

[0267] The light guiding component 131 can be bent into a concave shape by its own weight (or self-load) and can be disposed on the reflector 133.

[0268] For example, when the rigidity of the light guiding member 131 is relatively low, the light guiding member 131 can be bent into a concave shape based on the reflective sheet 133 (or the rear portion 310) and can be disposed on the reflective sheet 133. Therefore, an internal air gap 132 does not need to be provided between the reflective sheet 133 and the light guiding member 131. On the other hand, when the rigidity of the light guiding member 131 is relatively high, the light guiding member 131 can bend without its own weight (or self-load) and can be mounted or disposed on the reflective sheet 133 in a planar state. Therefore, an internal air gap 132 can be provided between the portions other than the two ends of the reflective sheet 133 and the light guiding member 131. For example, the distance (or size) of the internal air gap 132 may increase, thus increasing the loss of sound waves in the high-pitched vocal bands, which is proportional to the distance. This could prevent the mid-to-high-pitched vocal bands from producing sound, or reduce the sound waves in the mid-to-high-pitched vocal bands. Furthermore, the mid-to-high-pitched vocal bands generated by the first vibration generating device 410 and the mid-to-low-pitched vocal bands generated by the second vibration generating device 430 may be separated from each other. Therefore, the light guiding member 131 may be formed of a rigid material bent into a non-conformal shape not based on the concave shape of the reflector 133 (or rear portion 310), and disposed on the reflector 133 to provide an internal air gap 132 between the light guiding member 131 and the reflector 133 overlapping with the intermediate region MA of the display module 100.

[0269] The light source component can illuminate the light incident surface in the light guiding component 131. The light source component can be disposed in the rear cover 300 to overlap with the peripheral area EA of the display panel 110. The light source component according to embodiments of the present disclosure may include a plurality of light-emitting diode (LED) devices mounted on a printed circuit board (PCB) for a light source and illuminating the light incident surface.

[0270] The optical sheet component 135 can be located on the front surface of the light guide component 131 and can enhance the luminance characteristics of the light output from the light guide component 131. The optical sheet component 135 can be disposed on the light guide component 131 in a conformal shape having a concave shape based on the light guide component 131.

[0271] Therefore, the display device according to the embodiments of this disclosure can have the same... Figures 1 to 18 The same effect is achieved with the illustrated display device. Furthermore, in the display device according to this embodiment, the internal air gap 132 provided between the reflector 133 and the light guiding member 131 of the backlight portion 130 can be used as a speaker by using the rear portion 310 of the rear cover 300, which has a cross-sectional structure with a concave curved shape, thereby further enhancing the sound characteristics of the bass band.

[0272] Figure 21This is a diagram illustrating the sound output characteristics of a display device according to an embodiment of the present disclosure. Figure 21 In the diagram, the thin solid line represents the frequency-sound pressure level characteristics of the display device (or the display device of the comparative example), which includes one side (or part) of the display device. Figure 6 The display device does not have open connecting components. (Thick solid line indicates...) Figure 8 The frequency-sound pressure level characteristics of the display device. The dashed line indicates... Figure 17 The frequency-sound pressure level characteristics of the display device. Figure 21 In the diagram, the horizontal axis represents frequency (Hz), and the vertical axis represents sound pressure level (dB). Figure 21 The sound pressure levels shown were measured using an Audio Precision APX525 audio analyzer (FFT analyzer). Furthermore, measurements were taken under conditions of an applied voltage of 3 Vrms, a sinusoidal scan from 20 Hz to 20 kHz, and a distance of 0.5 m between the display panel and the measurement position. A sinusoidal scan can be performed for a short period, but is not limited to this method.

[0273] refer to Figure 21 Compared to the display device of the comparison example, it can be seen that, Figure 8 and Figure 17 In the display device, the sound pressure level is enhanced in low-frequency sound levels of 200Hz or below. For example, compared with the comparative example display device, it can be seen that... Figure 8 and Figure 17 In the display device, the sound pressure level at 200Hz or lower was enhanced by approximately 10dB or more. Therefore, compared to the display device of the comparative example, it can be seen that... Figure 8 and Figure 17 In the display device, the sound pressure level of the bass-heavy sound band is enhanced. For example, this enhancement can be seen because the back cover incorporates non-ferrous metal.

[0274] Furthermore, compared to the display device of the comparative example, it can be seen that, Figure 8 and Figure 17 In the display device, the sound pressure level in the mid-tone vocal band from 200Hz to 3kHz was increased by approximately 5dB to approximately 8dB or more. Compared to the display device of the comparative example, it can be seen that... Figure 8 and Figure 17In the display device, the sound pressure level in the high-pitched vocal bands at 3 kHz or higher is enhanced by about 5 dB to about 7 dB or higher. Therefore, in the display device according to embodiments of the present disclosure, it can be seen that the sound of the high-pitched vocal bands is enhanced. For example, although a piezoelectric vibration device with a strong output for the high-pitched vocal bands is not provided, a display device including a vibration generating module for outputting the sound of the high-pitched vocal bands can be provided. Therefore, a display device including a vibration generating module for enhancing the sound of the low-pitched vocal bands to the low-pitched vocal bands can be provided.

[0275] The display device according to embodiments of this disclosure can be applied to various applications that output sound based on the vibration of the display module without a separate speaker.
