Description

Technical Field

[0001] This specification relates to a display device, and more particularly, to a display device having a structure in which a camera module can be stably attached.

Background Art

[0002] The content described herein merely provides background information related to the present invention and does not constitute prior art.

[0003] As we enter the full-fledged information age, the field of display devices that visually display electrical information signals has been rapidly developing, and research has been continuously conducted to develop performance such as thinning, weight reduction, and low power consumption for various display devices.

[0004] These display devices include liquid crystal display devices (LCD), quantum dot display panel devices (QD), field emission display devices (FED), electro-wetting display devices (EWD), and organic light emitting display devices (OLED).

[0005] Display devices have been developed to be miniaturized so that users can carry and move them, or attached to mobile devices such as vehicles, and improved to be more conveniently utilized by users.

Summary of the Invention

Problems to be Solved by the Invention

[0006] A camera module may be disposed in the display device to capture an external image.

[0007] In a conventional display device, when a camera module is provided, a separate area for arranging the camera module is provided. That is, the camera module is arranged at a separate position away from the display module.

[0008] In these conventional structures, in order to provide a separate area for arranging the camera module, the area of the display module becomes smaller, and the overall area of the display device becomes larger.

[0009] As a result, even if the display device is enlarged, the screen size that the user can actually view the video becomes smaller, and the area efficiency and volume efficiency of the display device decrease.

[0010] In order to compensate for the disadvantages of the conventional ones, in recent years, the display device may be arranged at the position where the display module is arranged without providing a separate area where the camera module is arranged.

[0011] When the camera module is arranged on the display module, a structure in which the camera module is stably attached to the display device and can maintain its position is required.

[0012] Therefore, an object of the present specification is to provide a display device having a structure in which a camera module can be stably attached.

[0013] Another object of the present specification is to provide a display device having a structure in which a camera module can be easily attached.

[0014] Another object of the present specification is to provide a display device having an attachment structure of a camera module that can be processed at a low cost.

[0015] The object of this specification is not limited to the objects mentioned above, and other objects and advantages of this specification not mentioned can be understood from the following description and can be more clearly understood from the embodiments of this specification. Also, it can be easily understood that the objects and advantages of this specification can be realized by the means shown in the claims and their combinations.

Means for Solving the Problems

[0016] One embodiment of the display device includes a camera module in which a lens barrel is disposed at a position having a first through hole formed in a display module, and a metal plate is formed at a position corresponding to the first through hole and includes a second through hole in which the lens barrel is disposed and a guide portion disposed so as to surround the second through hole and protruding in the direction of the camera module.

[0017] A plurality of guide portions are provided, and each guide portion surrounds the body at a distance from each other and can determine the arrangement position of the body.

[0018] The guide portion may include a forming hole for forming the guide portion in the metal plate, and a portion adjacent to the forming hole may be bent to be formed.

[0019] The metal plate may include a rib formed along the circumferential direction of the second through hole at the edge of the second through hole and protruding in the direction of the camera module.

[0020] The rib may be formed by bending a portion of the metal plate in contact with the second through hole.

[0021] One embodiment of a display device includes a camera module in which a lens barrel is disposed at a position where a first through hole is formed in a display module, a cover member disposed in front of the display module so as to cover the first through hole, and a chip on film (COF) having one side electrically connected to the display module and the other side electrically connected to a printed circuit board. A metal plate is formed at a position corresponding to the first through hole and includes a second through hole where the lens barrel is disposed, a guide portion disposed so as to surround the second through hole and protruding in the direction of the camera module, and a rib formed along the circumferential direction of the second through hole at the edge of the second through hole and protruding in the direction of the camera module.

[0022] The guide portion may include a formation hole for forming the guide portion in the metal plate, with a portion adjacent to the formation hole being bent, and the rib may be formed by bending a portion of the metal plate that contacts the second through hole.

Advantages of the Invention

[0023] In the display device according to an embodiment of the present invention, the camera module is stably attached to the metal plate by the guide portion and the rib. Specifically, the lens barrel may be disposed inside the rib.

[0024] At this time, the body is disposed so as to be surrounded by a plurality of guide portions, and the end of the rib may be fitted into a fitting groove. In this way, due to the double structure of the guide portion and the rib, the camera module can be stably attached to the metal plate and maintain the fitting position.

[0025] Further, in the display device of the present invention, when attaching the camera module to the display device, since the fitting position is determined by the guide portion and the rib, the operator does not need to separately set the arrangement position of the camera module and only needs to sandwich the camera module between the guide portion and the rib. Therefore, the camera module can be easily attached to the display device.

[0026] In the display device of the present invention, a guide portion and ribs are formed on the metal plate by punching and bending processes, and a separate mold does not need to be used for casting, die casting, injection, etc.

[0027] Therefore, the process of forming the guide portion and the ribs is easy, the manufacturing process of the display device is simplified, and the manufacturing cost can be reduced. In addition, in forming the guide portion and the ribs having a relatively small volume in the whole display device, the defective rate can be significantly reduced compared with methods such as casting.

[0028] The above-described effects and the specific effects of the present invention will be described and described while explaining the mode for carrying out the following invention.

[0035] In the following description, when a user views the display device in a state where the display device is arranged for daily use, the direction in which the user is located is referred to as "front", and the opposite direction of the front is referred to as "rear".

[0036] Also, "up and down", "upper side", "lower side", "upper part" or "lower part" mean the position or direction of each component in a state where the display device is arranged for daily use. In the drawings, the front means the +z direction, the rear means the -z direction, and up and down mean the x-axis direction, respectively.

[0037] The display device according to an embodiment can be attached to, for example, the cockpit of a vehicle to provide necessary images or pictures for driving to the driver and passengers of the vehicle. However, it is not limited to this, and it can also be used by a user without being attached to a vehicle. Hereinafter, for example, a display device attached to a vehicle will be described.

[0038] FIG. 1 is a front view showing a display device according to an embodiment. FIG. 2 is a rear view showing a display device according to an embodiment.

[0039] A display device according to an embodiment may include a display module 110 (see FIG. 10), a metal plate 120, a cover member 150, a bezel 170, a printed circuit board 130, a chip on film 160 (COF), and a camera module 140.

[0040] The display module 110 can be provided to reproduce video or images. The video or images to be reproduced may be navigation information necessary for driving, video captured by a camera attached to the vehicle, or various other contents necessary for the driver or passengers.

[0041] A first through-hole 111 may be formed in the display module 110 such that the lens barrel 141 of the camera module 140 is disposed within the display area of the display panel 113. Thus, the lens barrel 141 can penetrate through the display module 110 and view the front of the display device to capture video. The specific structure of the display module 110 will be described below.

[0042] The metal plate 120 may be disposed behind the display module 110. The metal plate 120 can function as a heat sink that dissipates the heat generated by the display panel 113 provided in the display module 110 to the outside and cools the display panel 113.

[0043] The metal plate 120 may be formed of, for example, aluminum, copper, or a metal material containing these, which have high heat transfer rates. However, it is not limited thereto.

[0044] The cover member 150 may be disposed in front of the display module 110 so as to cover the first through-hole 111. The cover member 150 may be disposed at the very front of the display device. The cover member 150 is disposed in front of the display panel 113 and can protect the display panel 113. The cover member 150 is formed of a transparent material, and the light irradiated from the display panel 113 can pass through the cover member 150.

[0045] Thus, the lens barrel 141 can receive the light passing through the cover member 150 made of a transparent material and capture an image in front of the display device.

[0046] The bezel 170 is arranged to surround the edges of the display module 110, the metal plate 120, and the cover member 150, connect these to each other, and can form a part of the appearance of the display device.

[0047] The printed circuit board 130 can be arranged behind the metal plate 120. The printed circuit board 130 is arranged behind the metal plate 120 and can be electrically connected to the display panel 113.

[0048] The printed circuit board 130 is provided with a camera module 140, a device for communicating with external devices such as the main control module of the vehicle, a device for driving the display panel 113 so that the display panel 113 reproduces video or images, and can be provided with a circuit, various other active elements and passive elements.

[0049] One side of the chip - on - film 160 can be electrically connected to the display module 110, and the other side can be electrically connected to the printed circuit board 130. The chip - on - film 160 can be attached to one surface of the display panel 113 of the display module 110 and be electrically connected to the display module 110.

[0050] A part of the chip - on - film 160 can be bent and arranged to surround the end of the metal plate 120. The chip - on - film 160 can be formed of a flexible material so as to be thin and bendable.

[0051] The chip - on - film 160 can electrically connect the display panel 113 and the printed circuit board 130. The chip - on - film 160 can be provided with various active elements and passive elements, and may be provided with a driving circuit for driving the display panel 113.

[0052] The driving circuit for driving the display panel 113 can also be provided so as to be dispersed on the printed circuit board 130 and the chip-on-film 160, respectively. The chip-on-film 160 may be provided with driving elements that form at least a part of the driving circuit of the display panel 113. A plurality of chip-on-films 160 can be provided. Each chip-on-film 160 can be arranged so as to be separated from each other.

[0053] The camera module 140 can be attached to the display device to capture an image in front of the display device. The camera module 140 may have the lens barrel 141 arranged at a position where the first through hole 111 formed in the display module 110 is located.

[0054] In a conventional display device, when the camera module 140 is provided, a separate area for arranging the camera module 140 is provided. That is, the camera module 140 is arranged at a separate position separated from the display module 110.

[0055] In the case of these conventional structures, in order to provide a separate area for arranging the camera module 140, the area of the display module 110 becomes smaller, and the overall area of the display device becomes larger.

[0056] As a result, even if the display device is enlarged, the size of the screen on which the user can actually view the video becomes smaller, and the area efficiency and volume efficiency of the display device decrease.

[0057] In recent years, in order to compensate for the disadvantages of the conventional ones, the display device can be arranged at the position where the display module 110 is arranged without providing a separate area where the camera module 140 is arranged. The display device according to the embodiment also has these structures.

[0058] When the camera module 140 is disposed on the display module 110, a structure is required in which the camera module 140 can be stably attached to the display device and maintain its position. This will be specifically described below.

[0059] First, the camera module 140 according to an embodiment will be described. FIG. 3 is a perspective view showing the front surface of the camera module 140 according to an embodiment. FIG. 4 is a perspective view showing the back surface of the camera module 140 according to an embodiment.

[0060] The camera module 140 can include an auto focusing (AF) device for taking a high-resolution image and an optical image stabilizing (OIS) device for correcting the shake of the camera module 140 due to an external impact.

[0061] The camera module 140 may include a body 142 and a lens barrel 141. The body 142 is connected to the printed circuit board 130, electricity is transmitted from the printed circuit board 130, and it can communicate with a control unit provided on the printed circuit board 130. Further, the body 142 can constitute various elements and circuits for controlling the AF and OIS operations of the lens barrel 141.

[0062] The lens barrel 141 protrudes from the body 142 and may include at least one lens. For example, the lens barrel 141 can be arranged with a plurality of lenses in various forms to enhance the resolution of the captured image.

[0063] The body 142 may include a fitting groove 1421. The fitting groove 1421 is formed in a shape corresponding to the rib 122 of the metal plate 120, and the rib 122 can be fitted therein. As will be described later, the rib 122 can be formed to protrude from the metal plate 120 in a ring shape.

[0064] Therefore, the insertion groove 1421 can be formed such that a part of the body 142 is recessed in a ring shape so as to surround the lens barrel 141, corresponding to the shape of the rib 122.

[0065] FIG. 5 is a partial view showing a state in which a preliminary through hole 121' is formed in the metal plate 120 according to an embodiment. FIG. 6 is a partial view showing a state in which the second through hole 121 is formed by performing processing on FIG. 5.

[0066] The metal plate 120 is a structure for attaching the camera module 140 and may include a second through hole 121 and a guide portion 124. The second through hole 121 is formed at a position corresponding to the first through hole 111, and the lens barrel 141 can be disposed therein. The second through hole 121 can be formed, for example, by punching the metal plate 120.

[0067] The lens barrel 141 is disposed in the second through hole 121, penetrates the metal plate 120, and can view the front of the display device. The body 142 can be disposed behind the metal plate 120.

[0068] The guide portion 124 is disposed so as to surround the second through hole 121 and can protrude in the direction of the camera module 140. A plurality of guide portions 124 are provided, and each guide portion 124 surrounds the body 142 at a distance from each other, and can determine the arrangement position of the body 142.

[0069] The plurality of guide portions 124 are disposed at the edge of the body 142 and can support the body 142. Therefore, the plurality of guide portions 124 need to be disposed at positions where the body 142 can be stably supported.

[0070] For example, the body 142 is formed as a hexahedron, and each of the plurality of guide portions 124 can be arranged to support each side of the body 142. With such a structure, the body 142 is placed inside the plurality of guide portions 124, whereby the plurality of guide portions 124 can determine the arrangement position of the body 142.

[0071] The body 142 attached to the guide portion 124 is stably supported by the guide portion 124 and can maintain the attached position. On the other hand, the rib 122 of the metal plate 120 described later can also determine the arrangement position of the body 142 together with the guide portion 124.

[0072] The metal plate 120 is a structure for attaching the camera module 140 and may further include ribs 122. The rib 122 is formed along the circumferential direction of the second through hole 121 at the edge of the second through hole 121 in the metal plate 120 and can protrude in the direction of the camera module 140.

[0073] When the rib 122 is inserted into the fitting groove 1421 formed in the body 142 of the camera module 140, the camera module 140 can be attached to the designed position of the metal plate 120 and maintain the attached position.

[0074] Since the rib 122 is sandwiched by the fitting groove 1421, the rib 122 and the fitting groove 1421 can be manufactured in shapes corresponding to each other. For example, the rib 122 and the fitting groove 1421 can be configured in a ring shape surrounding the lens barrel 141. On the other hand, the plurality of guide portions 124 can be configured to surround the rib 122.

[0075] The rib 122 is formed by bending a part of the metal plate 120. However, by providing the rib 122 in a ring shape, the bending process is easier compared to other shapes, and the manufacturing of the rib 122 can be facilitated.

[0076] In an embodiment, the camera module 140 can be stably attached to the metal plate 120 by the guide portion 124 and the rib 122. Specifically, the lens barrel 141 can be disposed inside the rib 122.

[0077] At this time, the body 142 is disposed so as to be surrounded by a plurality of guide portions 124, and the end of the rib 122 can be fitted into the fitting groove 1421. In this way, due to the double structure of the guide portion 124 and the rib 122, the camera module 140 can be stably attached to the metal plate 120 and maintain the attached position.

[0078] In an embodiment, when attaching the camera module 140 to the display device, since the attachment position is determined by the guide portion 124 and the rib 122, the operator does not need to separately set the arrangement position of the camera module 140, and only needs to sandwich the camera module 140 between the guide portion 124 and the rib 122. Therefore, the camera module 140 can be easily attached to the display device.

[0079] When forming the guide portion 124 and the rib 122 on the metal plate 120, for example, methods such as casting, die casting, and injection can be used. However, these methods may require a separate mold.

[0080] Also, the camera module 140 may be very small compared to the overall size of the display device, and the guide portion 124 and the rib 122 for attaching it can also be provided very small. Therefore, it is difficult to form the very small guide portion 124 and rib 122 on the metal plate 120 by methods such as casting, and there is a high possibility of defects.

[0081] Hereinafter, specifically, forming the guide portion 124 and the rib 122 using bending processing, which is simpler and has a lower defect rate compared to methods such as casting, will be described.

[0082] The guide portion 124 is provided with a forming hole 123 for forming the guide portion 124 in the metal plate 120, and the portion adjacent to the forming hole 123 can be bent and formed.

[0083] Since the metal plate 120 is made of a metal with very excellent malleability and ductility, the guide portion 124 and the rib 122 with a relatively small volume can be formed by bending.

[0084] Referring to FIG. 5, a forming hole 123 can be made at the designed position on the metal plate 120 by punching to form the guide portion 124. The forming holes 123 can be formed at a plurality of positions spaced apart from each other, for example, so as to surround the second through hole 121 or the preliminary through hole 121' in a "U" shape.

[0085] At this time, a second region 124' that will become the guide portion 124 in the future can be formed by the forming hole 123. In the bending process, the second region 124' is bent and protrudes forward, and thereby, the second region 124' can become the guide portion 124.

[0086] These bending processes can be performed manually by an operator or using an automated vent machine.

[0087] The rib 122 can be formed by bending the portion of the metal plate 120 that contacts the second through hole 121. The diameter of the second through hole 121 can increase when the rib 122 is bent. The second through hole 121 can be formed by expanding the diameter of a relatively small-diameter hole when the rib 122 is bent.

[0088] Referring to FIG. 5, first, a preliminary through hole 121' with a relatively small diameter can be formed at the designed position on the metal plate 120 by punching. A first region 122' that will become the rib 122 in the future can exist in a ring shape at the position surrounding the preliminary through hole 121' of the metal plate 120.

[0089] By bending, the first region 122' protrudes forward, and thus, the first region 122' can become the rib 122. For example, when a rod-shaped tool having a diameter identical to or extremely similar to that of the second through-hole is sandwiched in the preliminary through-hole 121' and pressure is applied, the first region 122' protrudes, and the rib 122 can be formed.

[0090] At this time, the relatively small-diameter preliminary through-hole 121' can have its diameter expanded and become the relatively large-diameter second through-hole as the rib 122 is bent and formed.

[0091] Since the metal plate 120 is extremely excellent in malleability and ductility, even if these bending processes are performed, the first region 122' of the metal plate 120 can be smoothly deformed into the rib 122 without breaking.

[0092] The guide portion 124 and the rib 122 can be easily formed by punching and bending in the manner described above.

[0093] In an embodiment, the guide portion 124 and the rib 122 are formed on the metal plate 120 by punching and bending, and a separate mold may not be used for casting, die-casting, injection, etc.

[0094] Therefore, the process of forming the guide portion 124 and the rib 122 is easy, the manufacturing process of the display device is simplified, and the manufacturing cost can be reduced. Further, in forming the guide portion 124 and the rib 122 having a relatively small volume in the whole display device, the defective rate can be significantly reduced as compared with methods such as casting.

[0095] The camera module 140 can enhance the area efficiency and space efficiency of the display device regardless of where it is disposed on the display module 110. However, for example, the camera module 140 can be disposed at a position overlapping with the printed circuit board 130.

[0096] Specifically, holes are formed in the printed circuit board 130 for inserting the lens barrel 141, and the lens barrel 141 can be disposed in these holes and arranged at a position overlapping the printed circuit board 130.

[0097] When the camera module 140 is disposed on the printed circuit board 130, a cable 126 for electrically connecting the camera module 140 and the printed circuit board 130 can be easily installed. Compared with the case where the camera module 140 is not disposed on the printed circuit board 130, the cable 126 can be shortened, and the space efficiency in the display device can be improved.

[0098] Hereinafter, a structure in which the camera module 140 is disposed on the printed circuit board 130, that is, a structure in which the camera module 140 and the printed circuit board 130 are disposed overlapping each other will be specifically described.

[0099] FIG. 7 is a partial view showing a portion where the third through hole 131 is formed in the printed circuit board 130 according to an embodiment. FIG. 8 is a partial view showing a state in which the metal plate 120 and the printed circuit board 130 are coupled.

[0100] The printed circuit board 130 may include a third through hole 131 and an insertion hole 132 for disposing the camera module 140. The third through hole 131 is formed at a position corresponding to the second through hole 121, and the lens barrel 141 can be disposed therein.

[0101] The lens barrel 141 is disposed in the third through hole 131, penetrates the printed circuit board 130, and also penetrates the first through hole 111 and the second through hole 121, so that an image can be captured by looking at the front of the display device.

[0102] The rib 122 can be inserted into the third through hole 131. The rib 122 is disposed so as to pass through the third through hole 131 and protrude forward, and the rib 122 may be sandwiched between the fitting grooves 1421 of the body 142. With these structures, the camera module 140 and the metal plate 120 disposed via the printed circuit board 130 can be coupled to each other.

[0103] The insertion hole 132 is formed at a position corresponding to the guide portion 124, and the guide portion 124 can be inserted therein. The insertion hole 132 may have the same number as or a smaller number than the number of the guide portions 124. That is, when the recessed groove 133 described later is formed in the printed circuit board 130 and the guide portion 124 is inserted therein, the insertion hole 132 may have a number smaller than the number of the guide portions 124.

[0104] For example, similar to the guide rib 122 surrounding the second through hole 121, the insertion hole 132 may be disposed so as to surround at least a part of the third through hole 131.

[0105] When the guide portion 124 is inserted into the insertion hole 132, the printed circuit board 130 can be stably disposed at the position designed on the metal plate 120. Further, the guide portion 124 passing through the insertion hole 132 protrudes forward, and the body 142 can be sandwiched between the guide portions 124 and supported by the guide portions 124. With such a structure, the camera module 140 and the metal plate 120 disposed via the printed circuit board 130 can be coupled to each other.

[0106] The printed circuit board 130 may include a recessed groove 133 separately from the insertion hole 132 for disposing the camera module 140. The recessed groove 133 is formed by the end portion of the printed circuit board 130 being recessed, and the guide portion 124 can be inserted therein.

[0107] Depending on the arrangement position of the camera module 140 on the printed circuit board 130, it is necessary to arrange the guide portion 124 at the end of the printed circuit board 130. In the case of such a structure, a recessed groove 133 is formed at the end of the printed circuit board 130, and a part of the plurality of guide portions 124 can be inserted into the recessed groove 133 and protrude forward.

[0108] Similar to the insertion hole 132, the guide portion 124 passing through the recessed groove 133 protrudes forward, and the body 142 can be sandwiched between the guide portions 124 and supported by the guide portions 124.

[0109] FIG. 9 is an enlarged view showing a portion A of FIG. 2. FIG. 10 is a cross-sectional view taken along the direction BB of FIG. 9. As shown in FIG. 9, the lens barrel 141 can be disposed in the second through area and the third through area when viewing the front of the display device through the first through hole.

[0110] The cover member 150 that closes the first through hole is made of a transparent material and does not block the field of view of the lens barrel 141.

[0111] Adhesion means can be provided to fixedly attach the camera module 140 to the display device. For example, the body 142 of the camera module 140 contacts the back surface of the printed circuit board 130, and thus, a double-sided tape can be used between the body 142 of the camera module 140 and the printed circuit board 130 to adhere to the printed circuit board 130 of the camera module 140.

[0112] The display module 110 according to an embodiment may include a back plate 112, a display panel 113, a polarizing plate 114, and a fixing member 115.

[0113] The back plate 112 can be disposed in front of the metal plate 120. The back plate 112 can be disposed between the display panel 113 and the metal plate 120. The back plate 112 can be attached to the rear surface of the display panel 113 to prevent the display panel 113 from bending and being damaged. That is, the back plate 112 can function to reinforce the rigidity of the display panel 113.

[0114] The back plate 112 can be provided in a film form, for example, and can be attached to the display panel 113. However, it is not limited thereto.

[0115] The display panel 113 is disposed in front of the back plate 112 and can reproduce an image or a picture. The reproduced image or picture may be navigation information necessary for driving, an image captured by a camera attached to the vehicle, or other various contents necessary for the driver or the passenger.

[0116] The display panel 113 can be electrically connected to the chip-on-film 160 and can be electrically connected to the printed circuit board 130 by the chip-on-film 160. Thereby, the control unit and the drive element provided in the chip-on-film 160 and / or the printed circuit board 130 can control the operation of the display panel 113.

[0117] The polarizing plate 114 can be disposed in front of the display panel 113. The polarizing plate 114 can be disposed between the display panel 113 and the fixing member 115. The polarizing plate 114 can prevent reflection of external light and improve outdoor visibility and contrast ratio of the image displayed on the display panel 113.

[0118] The fixing member 115 can be disposed in front of the polarizing plate 114. The fixing member 115 is disposed between the cover member 150 and the display panel 113, and can attach the display panel 113 and the cover member 150 to each other. Since the light irradiated from the display panel 113 must pass through the fixing member 115, it can be formed of a transparent material.

[0119] Therefore, the fixing member 115 can be formed of, or include, a material that is transparent and has good adhesion, such as a substance like OCA (Optical Clear Adhesive), OCR (Optical Clear Resin), or PSA (Pressure Sensitive Adhesive).

[0120] The first through hole 111 can be formed excluding the display panel 113, the polarizing plate 114, and the fixing member 115. A light-shielding layer can be disposed on the side surfaces of the display panel 113, the polarizing plate 114, and the fixing member 115 disposed in the first through hole 111 to prevent light leakage.

[0121] On the other hand, a cushion plate can be disposed between the back plate 112 and the metal plate 120 for buffering. The cushion plate can mitigate the impact applied to various components of the display device and can include an emboss layer and a cushion layer.

[0122] The emboss layer can be disposed behind the back plate 112. The emboss layer can be disposed to adhere to the back plate 112 and can be formed of an adhesive layer having an emboss pattern. In one example, the emboss pattern of the emboss layer may be a concavo-convex structure formed on the surface.

[0123] Since the emboss layer can be in direct contact with the back plate 112 to fix the cushion layer to the back plate 112, it contains an adhesive component and can also perform the function of an adhesive layer. The emboss layer can be formed of, or include, a substance like OCA, OCR, or PSA.

[0124] The emboss layer may have a thickness of at least 40 μm at a minimum for the adhesion function and bubble prevention.

[0125] The cushion layer may be disposed between the emboss layer and the metal plate 120. The cushion layer may be formed of a foam tape or a foam pad. The cushion layer can function to mitigate the impact of various components that can come into contact with the cushion plate. Also, the cushion layer can reinforce the rigidity of the cushion plate.

[0126] In other embodiments, the cushion plate may include a porous member. The porous member may adhere to the emboss layer or the cushion layer and become an element forming the cushion plate. The porous member may be a metal foam.

[0127] The porous member can function as a kind of cushioning means together with the cushion layer and can mitigate the impact of various components that can come into contact with the cushion plate. Also, the porous member can be formed of a metal material and reinforce the rigidity of the cushion plate.

[0128] The lens barrel 141 is disposed within a first through hole 111 formed in the display module 110, is disposed below the display panel 113, and a spaced space can be formed between the lens barrel 141 and the cover member 150.

[0131] In an embodiment, the camera module 140 can be disposed at a position overlapping the printed circuit board 130 in the front-rear direction of the display device. Also, the connector 125 can be provided on the printed circuit board 130.

[0132] With such a structure, the cable 126 connecting the camera module 140 and the printed circuit board 130 can be disposed so as to overlap the printed circuit board 130 in the front-rear direction of the display device.

[0133] Therefore, the cable 126 can be provided relatively short, and the extra space for disposing the cable 126 can be minimized. Also, on the xy plane perpendicular to the front-rear direction, there is no need to provide a separate space for disposing the cable 126.

[0134] By disposing the camera module 140 so as to overlap the printed circuit board 130 and minimizing the extra space for disposing the cable 126, the area efficiency and space efficiency of the display device can be improved.
