Abstract
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 is rapidly developing, and research is continuously being conducted to develop performance such as thinning, lightening, and low power consumption for various display devices.
[0004] These display devices include a liquid crystal display device (LCD), a quantum dot display panel device (QD), a field emission display device (FED), an electro-wetting display device (EWD), and an organic light emitting display device (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 convenient for users to utilize.
Summary of the Invention
Problems to be Solved by the Invention
[0006] A camera module may be disposed in the display device for capturing an external image.
[0007] In conventional display devices, if a camera module is included, a separate area is provided for the camera module. That is, the camera module is positioned at a separate location, away from the display module.
[0008] In these conventional structures, the area of the display module is reduced to accommodate the camera module, resulting in a larger overall area for the display device.
[0009] As a result, even if the display device becomes larger, the actual screen size that users can see the image on becomes smaller, and the area efficiency and volume efficiency of the display device decrease.
[0010] To compensate for the shortcomings of conventional designs, in recent years, display devices are sometimes placed in the same location as the camera module, without requiring a separate area for the camera module.
[0011] When a camera module is placed on a display module, a structure is required that allows the camera module to be stably attached to the display device and maintain its position.
[0012] Therefore, the objective of this specification is to provide a display device having a structure that allows a camera module to be stably mounted.
[0013] Another objective of this specification is to provide a display device having a structure that allows for easy attachment of a camera module.
[0014] Another objective of this specification is to provide a display device having a camera module mounting structure that can be manufactured at low cost.
[0015] The purposes of this specification are not limited to those mentioned above. Other purposes and advantages of this specification not mentioned can be understood from the following description and more clearly from the embodiments described herein. Furthermore, it is readily apparent that the purposes and advantages of this specification can be achieved by the means and combinations thereof described in the claims. [Means for solving the problem]
[0016] One embodiment of the display device includes a camera module in which a lens barrel is positioned at a location having a first through-hole formed in the display module, and the metal plate may include a second through-hole formed at a location corresponding to the first through-hole in which the lens barrel is positioned, and a guide portion positioned to surround the second through-hole and projecting toward the camera module.
[0017] Multiple guide units are provided, each of which surrounds the body at a distance from the others, allowing for the determination of the body's position.
[0018] The guide portion is provided with a forming hole in the metal plate for forming the guide portion, and the portion adjacent to the forming hole may be formed in a curved shape.
[0019] The metal plate may include ribs formed along the circumferential direction of the second through-hole at the edge of the second through-hole, projecting toward the camera module.
[0020] The rib may be formed with a curve at the portion that contacts the second through-hole in the metal plate.
[0021] One embodiment of the display device includes a camera module in which a lens barrel is positioned at a location where a first through-hole is formed in the display module; a cover member positioned in front of the display module so as to cover the first through-hole; and a chip-on-film (COF) which is electrically connected to the display module on one side and to a printed circuit board on the other side. The metal plate may include a second through-hole formed at a location corresponding to the first through-hole in which the lens barrel is positioned; a guide portion positioned to surround the second through-hole and projecting toward the camera module; and a rib formed along the circumferential direction of the second through-hole and projecting toward the camera module.
[0022] The guide portion is formed by providing a forming hole in the metal plate for creating the guide portion, with the portion adjacent to the forming hole being curved, and the rib may be formed with a curve at the portion in contact with the second through hole in the metal plate. [Effects of the Invention]
[0023] In a display device according to one embodiment of the present invention, the camera module is stably attached to a metal plate by guides and ribs. Specifically, the lens barrel may be positioned inside the ribs.
[0024] In this configuration, the body is positioned so as to be surrounded by multiple guide sections, and the ends of the ribs can be fitted into the fitting grooves. Thus, the dual structure of the guide sections and ribs allows the camera module to be stably attached to the metal plate and maintain its fitted position.
[0025] Furthermore, in the display device of the present invention, when attaching the camera module to the display device, the insertion position is determined by the guide portion and the rib, so the operator does not need to separately set the placement position of the camera module; they only need to sandwich the camera module between the guide portion and the rib. Thus, the camera module can be easily attached to the display device.
[0026] In addition, in the display device of the present invention, a guide portion and ribs are formed on a metal plate by punching and bending, and a separate mold may not 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 as compared with methods such as casting.
[0028] The above-described effects as well as the specific effects of the present invention will be described and described while explaining the embodiments for carrying out the following invention.

[Modes for carrying out the invention]
[0030] The aforementioned objectives, features, and advantages will be described in detail below with reference to the accompanying drawings, so that a person with ordinary skill in the art to which the present invention pertains can implement the technical idea of the present invention. In describing the present invention, if a specific description of known technology according to the present invention is deemed to obscure the gist of the present invention, the detailed description will be omitted. Hereafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings are used to indicate the same or similar components.
[0031] Although terms such as "First," "Second," etc., are used to describe various components, these components are not limited by these terms. These terms are simply used to distinguish one component from another, and unless otherwise specified, the first component may also be the second component.
[0032] Throughout the specification, unless otherwise stated, each component may be singular or plural.
[0033] In this specification, singular expressions include plural expressions unless the context clearly indicates otherwise. In this application, terms such as “composed of” or “including” should not be construed as including any of the multiple components or stages described in the specification, and should be construed as including some of the components or stages which may not be included, or which may include further components or stages.
[0034] Throughout the specification, "A and / or B" means A, B, or A and B unless otherwise specified, and "C to D" means C or greater and D or less unless otherwise specified.
[0035] In the following explanation, assuming the display device is positioned for everyday use, the direction from which the user is looking at the display device will be referred to as "front," and the opposite direction will be referred to as "rear."
[0036] Furthermore, "up and down," "upper side," "lower side," "top," or "bottom" refer to the position or orientation of each component when the display device is positioned for everyday use. In drawings, "forward" refers to the +z direction, "backward" refers to the -z direction, and "up and down" refers to the x-axis direction.
[0037] The display device according to this embodiment can be mounted in the cockpit of a vehicle to provide the driver and passengers with the video or images necessary for driving. However, it is not limited to this, and can also be used by the user without being mounted in a vehicle. Below, we will describe, for example, a display device that can be mounted in a vehicle.
[0038] Figure 1 is a front view showing a display device according to one embodiment. Figure 2 is a rear view showing a display device according to one embodiment.
[0039] A display device according to one embodiment may include a display module 110 (see Figure 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 may be equipped with a function to play video or images. The video or images to be played may be navigation information necessary for driving, video footage taken by a camera mounted on the vehicle, or various other content necessary for the driver or passengers.
[0041] The display module 110 may have a first through-hole 111 formed within the display area of the display panel 113, through which the lens barrel 141 of the camera module 140 is positioned. Thus, the lens barrel 141 can penetrate the display module 110, view the front of the display device, and capture images. The specific structure of the display module 110 is described below.
[0042] The metal plate 120 may be positioned behind the display module 110. The metal plate 120 can function as a heat sink to dissipate heat generated by the display panel 113 of the display module 110 to the outside, thereby cooling the display panel 113.
[0043] The metal plate 120 may be formed from, for example, aluminum, copper, or a metal material containing these, which has high thermal conductivity. However, it is not limited to these materials.
[0044] The cover member 150 may be positioned in front of the display module 110 so as to cover the first through-hole 111. The cover member 150 may be positioned at the very front of the display device. The cover member 150 can be positioned in front of the display panel 113 to protect the display panel 113. The cover member 150 is made of a transparent material so that light shining from the display panel 113 can pass through the cover member 150.
[0045] Therefore, the lens barrel 141 can receive light passing through the transparent cover member 150, and can capture an image of the front of the display device.
[0046] The bezel 170 is positioned to surround the edges of the display module 110, the metal plate 120, and the cover member 150, connecting them together and forming part of the exterior appearance of the display device.
[0047] The printed circuit board 130 may be positioned behind the metal plate 120. The printed circuit board 130 can be positioned behind the metal plate 120 and electrically connected to the display panel 113.
[0048] The printed circuit board 130 may include a camera module 140, a device for communicating with external devices such as the vehicle's main control module, a device for driving the display panel 113 so that the display panel 113 plays video or images, and other circuits, as well as various other active and passive elements.
[0049] The chip-on film 160 can be electrically connected to the display module 110 on one side and to the printed circuit board 130 on the other side. The chip-on film 160 can be attached to one surface of the display panel 113 of the display module 110 and electrically connected to the display module 110.
[0050] The chip-on film 160 may be partially bent and positioned to surround the edge of the metal plate 120. The chip-on film 160 may be formed in a thin and flexible material so that it is 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 may be equipped with various active and passive elements, and may also be equipped with a drive circuit for driving the display panel 113.
[0052] The drive circuit for driving the display panel 113 may be provided so as to be distributed on the printed circuit board 130 and the chip-on film 160, respectively. The chip-on film 160 may be provided with drive elements that form at least a part of the drive circuit for the display panel 113. Multiple chip-on films 160 may be provided. Each chip-on film 160 may be arranged to be spaced apart from one another.
[0053] The camera module 140 can be attached to a display device to capture an image of the front of the display device. The camera module 140 may have a lens barrel 141 positioned at the location of the first through hole 111 formed in the display module 110.
[0054] In conventional display devices, if a camera module 140 is included, a separate area is provided for arranging the camera module 140. That is, the camera module 140 is positioned at a separate location, separated from the display module 110.
[0055] In these conventional structures, the area of the display module 110 becomes smaller in order to provide a separate area for the camera module 140, and the overall area of the display device becomes larger.
[0056] As a result, even if the display device becomes larger, the actual screen size that users can see the image on becomes smaller, reducing the area efficiency and volume efficiency of the display device.
[0057] To compensate for the shortcomings of conventional designs, in recent years, display devices can be positioned at the same location as the display module 110, without requiring a separate area for the camera module 140. Display devices according to the embodiments also have these structures.
[0058] When the camera module 140 is placed on the display module 110, a structure is required that allows the camera module 140 to be stably attached to the display device and maintain its position. This will be explained in detail below.
[0059] First, a camera module 140 according to one embodiment will be described. Figure 3 is a perspective view showing the front of the camera module 140 according to one embodiment. Figure 4 is a perspective view showing the rear of the camera module 140 according to one embodiment.
[0060] The camera module 140 may be equipped with an autofocus (AF) device and an optical image stabilizing (OIS) device to compensate for camera module 140 shaking caused by external shocks, in order to capture high-resolution images.
[0061] The camera module 140 may include a body 142 and a lens barrel 141. The body 142 is connected to a printed circuit board 130, receives electricity from the printed circuit board 130, and can communicate with a control unit provided on the printed circuit board 130. The body 142 can also be configured with various elements and circuits to control 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 may have multiple lenses of various configurations arranged to increase 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, into which the rib 122 can be fitted. As will be described later, the rib 122 may be formed to protrude from the metal plate 120 in a ring shape.
[0064] Therefore, the fitting groove 1421 can be formed in a ring shape, corresponding to the shape of the rib 122, so that a part of the body 142 is recessed and surrounds the lens barrel 141.
[0065] Figure 5 is a partial view showing the state in which a preliminary through hole 121' has been formed in a metal plate 120 according to one embodiment. Figure 6 is a partial view showing the state in which the processing in Figure 5 has been carried out and the second through hole 121 has been formed.
[0066] The metal plate 120 is a structure for mounting 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 a lens barrel 141 may be positioned therein. The second through-hole 121 may be formed, for example, by punching into the metal plate 120.
[0067] The lens barrel 141 is positioned in the second through-hole 121, penetrates the metal plate 120, and allows viewing in front of the display device. The body 142 may be positioned behind the metal plate 120.
[0068] The guide portion 124 is positioned to surround the second through hole 121 and may protrude in the direction of the camera module 140. Multiple guide portions 124 are provided, and each guide portion 124 is spaced apart from the others to surround the body 142 and determine the position of the body 142.
[0069] Multiple guide portions 124 are positioned along the edge of the body 142 to support the body 142. Therefore, the multiple guide portions 124 need to be positioned in a location that can stably support the body 142.
[0070] For example, the body 142 may be formed as a hexahedron, with each of the multiple guide portions 124 positioned to support each edge of the body 142. In such a structure, the body 142 is placed inside the multiple guide portions 124, thereby allowing the multiple guide portions 124 to determine the 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 its attached position. Meanwhile, the ribs 122 of the metal plate 120, described later, can also determine the position of the body 142 together with the guide portion 124.
[0072] The metal plate 120 is a structure for mounting the camera module 140 and may further include ribs 122. The ribs 122 are formed on the edge of the second through hole 121 in the metal plate 120 along the circumferential direction of the second through hole 121 and may protrude toward the camera module 140.
[0073] The rib 122 fits into the insertion groove 1421 formed in the body 142 of the camera module 140, thereby allowing the camera module 140 to be attached to the designed position on the metal plate 120 and to maintain that attached position.
[0074] Since the rib 122 is sandwiched in the fitting groove 1421, the rib 122 and the fitting groove 1421 can be manufactured in corresponding shapes. 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 multiple 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, but by providing the rib 122 in a ring shape, it is easier to bend compared to other shapes, which can make the manufacturing of the rib 122 easier.
[0076] In one 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 may be positioned inside the rib 122.
[0077] In this configuration, the body 142 is positioned so as to be surrounded by multiple guide portions 124, and the ends of the ribs 122 can be fitted into the fitting grooves 1421. Thus, the double structure of the guide portions 124 and the ribs 122 allows the camera module 140 to be stably attached to the metal plate 120 and maintain its attached position.
[0078] In this embodiment, when attaching the camera module 140 to the display device, the mounting position is determined by the guide portion 124 and the rib 122. Therefore, the operator does not need to separately set the placement position of the camera module 140; they only need to sandwich the camera module 140 between the guide portion 124 and the rib 122. Thus, the camera module 140 can be easily attached to the display device.
[0079] When forming the guide portion 124 and rib 122 on the metal plate 120, methods such as casting, die casting, and injection molding can be used. However, these methods may require a separate mold.
[0080] Furthermore, the camera module 140 can be very small compared to the overall size of the display device, and the guide portion 124 and rib 122 for attaching it can also be very small. Therefore, it is difficult to form the guide portion 124 and rib 122, which are formed to be very small, on the metal plate 120 by methods such as casting, and there is a high possibility of defects occurring.
[0081] The following section specifically describes how to form the guide portion 124 and the rib 122 using bending, which is simpler and has a lower defect rate compared to methods such as casting.
[0082] The guide portion 124 is provided with a forming hole 123 in the metal plate 120 for forming the guide portion 124, and the portion adjacent to the forming hole 123 may be formed in a curved shape.
[0083] Since the metal plate 120 is made of a metal with excellent malleability and ductility, it is possible to form relatively small volume guide portions 124 and ribs 122 by bending.
[0084] Referring to Figure 5, the forming holes 123 can be created in the metal plate 120 by punching to form guide portions 124 at the designed positions. Multiple forming holes 123 may be formed at positions spaced apart from each other, for example, in a "U" shape surrounding the second through hole 121 or preliminary through hole 121'.
[0085] At this time, the formed hole 123 may create a second region 124' which will later become the guide portion 124. During the bending process, the second region 124' is bent and protrudes forward, thereby allowing the second region 124' to become the guide portion 124.
[0086] These bending processes can be performed manually by workers or using automated bending machines.
[0087] The rib 122 may 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 may increase due to the bending of the rib 122. The second through hole 121 may be formed by expanding the diameter of a relatively small hole due to the bending of the rib 122.
[0088] Referring to Figure 5, first, a relatively small diameter preliminary through-hole 121' can be formed in the metal plate 120 at the designed location by punching. Surrounding the preliminary through-hole 121' in the metal plate 120, a ring-shaped first region 122' can exist, which will later become a rib 122.
[0089] Bending causes the first region 122' to protrude forward, thereby allowing the first region 122' to become a rib 122. For example, by inserting a rod-shaped tool with a diameter identical or very similar to that of the second through-hole into the preliminary through-hole 121' and applying pressure, the first region 122' may protrude, forming a rib 122.
[0090] At this time, the preliminary through-hole 121', which has a relatively small diameter, can expand in diameter as the rib 122 is bent, and become a second through-hole with a relatively larger diameter.
[0091] Because the metal plate 120 has excellent malleability and ductility, even when these bending processes are performed, the first region 122' of the metal plate 120 can deform smoothly without breaking and become a rib 122.
[0092] The guide portion 124 and the rib 122 can be easily formed by punching and bending using the method described above.
[0093] In this embodiment, guide portions 124 and ribs 122 are formed on the metal plate 120 by punching and bending, eliminating the need to use a separate mold for casting, die casting, injection, etc.
[0094] Therefore, the processing to form the guide portion 124 and the rib 122 is easy, simplifying the manufacturing process of the display device and reducing manufacturing costs. Furthermore, in forming the guide portion 124 and the rib 122, which occupy a relatively small volume in the overall display device, the defect rate can be significantly reduced compared to methods such as casting.
[0095] Regardless of where the camera module 140 is positioned on the display module 110, it can improve the area efficiency and spatial efficiency of the display device. However, for example, the camera module 140 may be positioned in a location that overlaps with the printed circuit board 130.
[0096] Specifically, holes are formed in the printed circuit board 130 into which the lens barrel 141 is inserted, and the lens barrel 141 can be positioned in these holes so that it overlaps with the printed circuit board 130.
[0097] When the camera module 140 is placed on the printed circuit board 130, the cable 126 for electrically connecting the camera module 140 and the printed circuit board 130 can be easily installed, and the cable 126 can be shortened compared to when the camera module 140 is not placed on the printed circuit board 130, thereby improving space efficiency in the display device.
[0098] The following describes in detail a structure in which the camera module 140 is placed on the printed circuit board 130, that is, a structure in which the camera module 140 and the printed circuit board 130 are superimposed on each other.
[0099] Figure 7 is a partial view showing a portion of the printed circuit board 130 in which the third through-hole 131 is formed according to one embodiment. Figure 8 is a partial view showing the state in which the metal plate 120 and the printed circuit board 130 are joined together.
[0100] The printed circuit board 130 may include a third through-hole 131 and an insertion hole 132 for arranging the camera module 140. The third through-hole 131 is formed in a position corresponding to the second through-hole 121, and a lens barrel 141 may be arranged therein.
[0101] The lens barrel 141 is positioned 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, allowing it to view the front of the display device and capture an image.
[0102] A rib 122 can be inserted into the third through-hole 131. The rib 122 is positioned to pass through the third through-hole 131 and protrude forward, and the rib 122 may be sandwiched in the fitting groove 1421 of the body 142. These structures allow the camera module 140 and the metal plate 120, which are arranged via the printed circuit board 130, to be coupled to each other.
[0103] The insertion holes 132 are formed at positions corresponding to the guide portion 124, into which the guide portion 124 can be inserted. The number of insertion holes 132 may be the same as or less than the number of guide portions 124. That is, if a recess groove 133, described later, is formed in the printed circuit board 130 and the guide portion 124 is inserted therein, the number of insertion holes 132 may be less than the number of guide portions 124.
[0104] For example, just as the guide rib 122 surrounds the second through hole 121, the insertion hole 132 may be positioned to surround at least a portion of the third through hole 131.
[0105] By inserting the guide portion 124 into the insertion hole 132, the printed circuit board 130 can be stably positioned on the metal plate 120 in the designed location. Furthermore, the guide portion 124 that has passed through the insertion hole 132 protrudes forward, so that the body 142 can be sandwiched between the guide portion 124 and supported by the guide portion 124. With this structure, the camera module 140 and the metal plate 120, which are positioned via the printed circuit board 130, can be coupled to each other.
[0106] The printed circuit board 130 may include a recessed groove 133 separate from the insertion hole 132 for arranging the camera module 140. The recessed groove 133 is formed by recessing the end of the printed circuit board 130, into which the guide portion 124 can be inserted.
[0107] Depending on the placement of the camera module 140 on the printed circuit board 130, it may be necessary to position the guide portion 124 at the edge of the printed circuit board 130. In such a structure, a recessed groove 133 is formed at the edge of the printed circuit board 130, and some of the multiple 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 that has passed through the recess groove 133 protrudes forward, so that the body 142 can be sandwiched between the guide portion 124 and supported by the guide portion 124.
[0109] Figure 9 is an enlarged view of portion A in Figure 2. Figure 10 is a cross-sectional view of Figure 9 in the direction BB. As shown in Figure 9, the lens barrel 141 may be positioned in the second and third through-holes, looking forward to 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 obstruct the field of view of the lens barrel 141.
[0111] The camera module 140 can be provided with means for permanently attaching it to the display device. For example, the body 142 of the camera module 140 can contact the back surface of the printed circuit board 130, and thus the camera module 140 can be attached to the printed circuit board 130 using double-sided tape between the body 142 and the printed circuit board 130.
[0112] A display module 110 according to one embodiment may include a back plate 112, a display panel 113, a polarizing plate 114, and a fixing member 115.
[0113] The backplate 112 may be positioned in front of the metal plate 120. The backplate 112 may be positioned between the display panel 113 and the metal plate 120. The backplate 112 can adhere to the rear surface of the display panel 113 to prevent the display panel 113 from bending and breaking. In other words, the backplate 112 can reinforce the rigidity of the display panel 113.
[0114] The backplate 112 may, for example, be provided in the form of a film and be attached to the display panel 113. However, it is not limited to this.
[0115] The display panel 113 is positioned in front of the backplate 112 and can play videos or images. The videos or images played may include navigation information necessary for driving, video footage captured by cameras mounted on the vehicle, or various other content necessary for the driver or passengers.
[0116] The display panel 113 is electrically connected to the chip-on film 160, and the chip-on film 160 is electrically connected to the printed circuit board 130. This allows the control unit and drive elements provided in the chip-on film 160 and / or the printed circuit board 130 to control the operation of the display panel 113.
[0117] The polarizing plate 114 may be positioned in front of the display panel 113. The polarizing plate 114 may be positioned 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 brightness ratio of the image displayed on the display panel 113.
[0118] The fixing member 115 may be positioned in front of the polarizing plate 114. The fixing member 115 can be positioned between the cover member 150 and the display panel 113 to allow the display panel 113 and the cover member 150 to adhere to each other. The fixing member 115 may be made of a transparent material because light irradiated from the display panel 113 must pass through it.
[0119] Therefore, the fixing member 115 may be formed from or include a transparent material with good adhesive strength, such as 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 may be placed on the side surfaces of the display panel 113, the polarizing plate 114, and the fixing member 115, which are positioned in the first through-hole 111, to prevent light leakage.
[0121] On the other hand, a cushioning plate may be placed between the backplate 112 and the metal plate 120 for buffering. The cushioning plate can mitigate the impact applied to various components of the display device and may include an embossed layer and a cushioning layer.
[0122] The embossed layer may be positioned behind the backplate 112. The embossed layer may be positioned to adhere to the backplate 112 and may be formed of an adhesive layer having an embossed pattern. The embossed pattern of the embossed layer may, in one example, be a surface-mounted uneven structure.
[0123] The embossed layer can directly contact the backplate 112 and fix the cushion layer to the backplate 112, and therefore can also function as an adhesive layer by containing an adhesive component. The embossed layer may be formed from or contain a substance such as OCA, OCR, or PSA.
[0124] The embossed layer may have a minimum thickness of 40 μm or more to provide adhesive properties and prevent air bubbles.
[0125] A cushioning layer may be placed between the embossed layer and the metal plate 120. The cushioning layer may be formed from foam tape or foam pad. The cushioning layer can function to mitigate the impact of various components that may come into contact with the cushioning plate. Furthermore, the cushioning layer can reinforce the rigidity of the cushioning plate.
[0126] In other embodiments, the cushion plate may include a porous member. The porous member may adhere to the embossed layer or cushion layer to form an element of the cushion plate. The porous member may be a metal foam.
[0127] The porous member can function as a type of cushioning mechanism in conjunction with the cushion layer, mitigating the impact on various components that may come into contact with the cushion plate. Furthermore, if the porous member is made of a metal material, it can reinforce the rigidity of the cushion plate.
[0128] The lens barrel 141 is positioned within the first through-hole 111 formed in the display module 110, below the display panel 113, and a space can be formed between the lens barrel 141 and the cover member 150.
[0129] Figure 11 shows a part of a printed circuit board 130 according to one embodiment. The camera module 140 is electrically connected to the printed circuit board 130, its operation is controlled by a control unit provided on the printed circuit board 130, and it can receive power from the printed circuit board 130.
[0130] For electrical connection between the camera module 140 and the printed circuit board 130, the printed circuit board 130 may be provided with a connector 125. The display device may also include a cable 126, one end of which is connected to the connector 125 and the other end of which is connected to the camera module 140, thereby electrically connecting the camera module 140 and the printed circuit board 130.
[0131] In one embodiment, the camera module 140 may be positioned so as to overlap the printed circuit board 130 in the front-to-back direction of the display device. The connector 125 may also be provided on the printed circuit board 130.
[0132] With this structure, the cable 126 connecting the camera module 140 and the printed circuit board 130 can be arranged so as to overlap the printed circuit board 130 in the front-to-back direction of the display device.
[0133] Therefore, the cable 126 can be relatively short, minimizing the extra space required to accommodate it. Furthermore, there is no need to provide additional space on the xy plane perpendicular to the front-to-back direction to accommodate the cable 126.
[0134] By arranging the camera module 140 so as to overlap with the printed circuit board 130, the extra space required for arranging the cable 126 can be minimized, thereby improving the area efficiency and spatial efficiency of the display device.
