Description

Technical Field

[0001] The present disclosure relates to a display device, and more particularly, to a display device having a structure capable of stably mounting a camera module therein. Background Art

[0002] The content described in this section only provides background information of the present disclosure and does not constitute related art.

[0003] In the era of all-round development of information, the field of display devices for visually displaying electrical information signals is developing rapidly, and research on developing the performance of various display devices, such as thinness, light weight, and low power consumption, is constantly ongoing.

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

[0005] Display devices have been developed to be miniaturized so that users can carry the display devices or install them on movable devices such as vehicles, and are being improved to make it more convenient for users to use the display devices. Summary of the Invention

[0006] The display device may be provided with a camera module for capturing an external image.

[0007] When a conventional display device is provided with a camera module, a separate area is provided to arrange the camera module. That is, the camera module is disposed at a separate position spaced apart from the display module.

[0008] In the case of the conventional structure, the area of the display module becomes smaller, and the total area of the display device becomes larger to provide a separate area for arranging the camera module.

[0009] Therefore, even when the display device becomes larger, the size of the screen on which the user can actually view an image becomes smaller, thereby reducing the area efficiency and volume efficiency of the display device.

[0010] To overcome the disadvantages of the prior art, recent display devices may be provided at a position where the display module is provided without a separate area for the camera module.

[0011] When the camera module is disposed on the display module, a structure capable of stably maintaining the position of the camera module mounted in the display device is required.

[0012] Therefore, the present disclosure aims to provide a display device having a structure capable of stably mounting a camera module.

[0013] In addition, the present disclosure aims to provide a display device having a structure in which a camera module can be simply installed.

[0014] In addition, the present disclosure aims to provide a display device having a mounting structure of a camera module that can be processed at low cost.

[0041] The display device according to an embodiment can be installed in, for example, the cockpit of a vehicle to provide videos or images required for driving to the driver and passengers of the vehicle. However, the present disclosure is not limited thereto, and the display device can be used when carried by a user instead of being installed in a vehicle. Hereinafter, for example, the display device installed in a vehicle will be described.

[0042] Figure 1 is a front view showing a display device according to an embodiment. Figure 2 is a rear view showing a display device according to an embodiment.

[0043] The display device according to an 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 (COF) 160, and a camera module 140.

[0044] The display module 110 may be configured to display videos or images. The videos or images to be displayed may be navigation information required for driving, videos captured by a camera installed in the vehicle, or various other contents required by the driver or passengers.

[0045] A first through hole 111 may be formed in the active area of the display panel 113 in the display module 110, and the lens barrel 141 of the camera module 140 is disposed through the first through hole 111. Accordingly, the lens barrel 141 may pass through the display module 110 to face the front of the display device and capture videos. The specific structure of the display module 110 will be described below.

[0046] The metal plate 120 may be disposed behind the display module 110. The metal plate 120 may be used as a heat sink for cooling the display panel 113 by dissipating heat generated from the display panel 113 provided in the display module 110 to the outside.

[0047] The metal plate 120 may be made of, for example, aluminum, copper, or a metal material including the same, which has a high heat transfer rate. However, the present disclosure is not limited thereto.

[0048] The cover member 150 may be configured to cover the first through hole 111 in front of the display module 110. The cover member 150 may be disposed at the very front of the display device. The cover member 150 may be disposed in front of the display panel 113 to protect the display panel 113. The cover member 150 may be made of a transparent material to allow light emitted from the display panel 113 to pass through the cover member 150.

[0049] Accordingly, since the light passing through the cover member 150 made of a transparent material can be incident on the lens barrel 141, an image in front of the display device can be captured.

[0050] The bezel 170 may be configured to surround the edges of the display module 110, the metal plate 120, and the cover member 150, couple the display module 110, the metal plate 120, and the cover member 150, and form a part of the appearance of the display device.

[0051] The printed circuit board 130 may be disposed behind the metal plate 120. The printed circuit board 130 may be disposed behind the metal plate 120 and electrically connected to the display panel 113.

[0052] The printed circuit board 130 may include a camera module 140, a device for communicating with an external device (e.g., a main control module of a vehicle), a device for driving the display panel 113 such that the display panel 113 displays video or images, etc., and is provided with circuits and various other active and passive components.

[0053] The COF 160 may have one side electrically connected to the display module 110 and the other side electrically connected to the printed circuit board 130. The COF 160 may be attached to one surface of the display panel 113 of the display module 110 and electrically connected to the display module 110.

[0054] The COF 160 may be configured such that a part thereof is bent to surround an end portion of the metal plate 120. The COF 160 may be formed thin and made of a flexible material to be able to be bent.

[0055] The COF 160 may electrically connect the display panel 113 to the printed circuit board 130. The COF 160 may be provided with various active and passive components and a driving circuit for driving the display panel 113.

[0056] The driving circuit for driving the display panel 113 may be configured to be dispersed to each of the printed circuit board 130 and the COF 160. The COF 160 may be provided with driving elements forming at least a part of the driving circuit of the display panel 113. A plurality of COF 160s may be provided. The COF 160s may be configured to be spaced apart from each other.

[0057] The camera module 140 is installed on the display device to capture a front image of the display device. The camera module 140 may have a lens barrel 141 disposed at a position where a first through hole 111 formed in the display module 110 is located.

[0058] When a conventional display device is provided with the camera module 140, a separate area in which the camera module 140 is provided is set. That is, the camera module 140 is disposed at a separate position spaced apart from the display module 110.

[0059] In the case of a conventional structure, in order to provide a separate area in which the camera module 140 is provided, the area of the display module 110 becomes smaller, and the total area of the display device becomes larger.

[0060] Therefore, even when the display device becomes larger, the size of the screen on which the user can actually view an image becomes smaller, thereby reducing the area efficiency and volume efficiency of the display device.

[0061] To compensate for the disadvantages of the related art, a recent camera module may be disposed at a position where the display module 110 is provided, without a separate area in which the camera module 140 is provided. The display device according to the present embodiment also has such a structure.

[0062] 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 mounted on the display device to maintain its position. This will be described in detail below.

[0063] First, the camera module 140 according to an embodiment will be described. Figure 3 is a perspective view showing a front surface of the camera module 140 according to an embodiment. Figure 4 is a perspective view showing a rear surface of the camera module 140 according to an embodiment.

[0064] To capture a high-resolution image, the camera module 140 may include an auto focus (AF) device and an optical image stabilization (OIS) device for correcting jitter of the camera module 140 due to external shock.

[0065] The camera module 140 may include a main body 142 and a lens barrel 141. The main body 142 may be connected to the printed circuit board 130 to receive power from the printed circuit board 130 and may communicate with a controller disposed on the printed circuit board 130. In addition, the main body 142 may be implemented with various elements and circuits for controlling the AF and OIS operations of the lens barrel 141.

[0066] The lens barrel 141 can protrude from the main body 142 and include at least one lens. For example, the lens barrel 141 can improve the resolution of the captured image by arranging a plurality of lenses of various types.

[0067] The main body 142 can include a seating groove 1421. The seating groove 1421 can be formed in a shape corresponding to the rib 122 of the metal plate 120, and the rib 122 can be seated therein. As will be described below, the rib 122 can be formed to protrude from the metal plate 120 in an annular shape.

[0068] Therefore, the seating groove 1421 can be formed in an annular shape to correspond to the shape of the rib 122, formed by the recessed portion of the main body 142, and formed to surround the lens barrel 141.

[0069] Figure 5 is a partial view showing the state of forming the preliminary through hole 121' in the metal plate 120 according to one embodiment. Figure 6 is for performing Figure 5 The process of to form the second through hole 121 is a partial view of the state.

[0070] The metal plate 120 is a structure for mounting the camera module 140, and can include a second through hole 121 and a guide portion 124. The second through hole 121 can be formed at a position corresponding to the first through hole 111, and the lens barrel 141 can be disposed in the second through hole. The second through hole 121 can be formed, for example, by stamping the metal plate 120.

[0071] The lens barrel 141 can be disposed in the second through hole 121 to pass through the metal plate 120 to view the front of the display device. The main body 142 can be disposed behind the metal plate 120.

[0072] The guide portion 124 can be disposed to surround the second through hole 121 and can protrude toward the camera module 140. A plurality of guide portions 124 can be disposed and spaced apart from each other to surround the main body 142 and determine the arrangement position of the main body 142.

[0073] A plurality of guide portions 124 can be disposed at the edge of the main body 142 to support the main body 142. Therefore, a plurality of guide portions 124 need to be disposed at positions where the main body 142 can be stably supported.

[0074] For example, the main body 142 can be formed in a hexahedron shape, and each of the plurality of guide portions 124 can be disposed to support each side of the main body 142. With this structure, the main body 142 can be disposed inside the plurality of guide portions 124, and thus the plurality of guide portions 124 can determine the arrangement position of the main body 142.

[0075] The main body 142 mounted on the guiding part 124 can be stably supported by the guiding part 124 to maintain the mounting position. Meanwhile, the rib 122 of the metal plate 120, which will be described below, can determine the arrangement position of the main body 142 together with the guiding part 124.

[0076] The metal plate 120 is a structure for mounting the camera module 140 and can additionally include ribs 122. The ribs 122 can be formed at the edge of the second through-hole 121 in the circumferential direction of the second through-hole 121 in the metal plate 120 and can protrude toward the camera module 140.

[0077] Since the rib 122 is seated in the seating groove 1421 formed in the main body 142 of the camera module 140, the camera module 140 can be mounted at the designed position of the metal plate 120 to maintain the mounting position.

[0078] Since the rib 122 is fitted into the seating groove 1421, the rib 122 and the seating groove 1421 can be manufactured in corresponding shapes. For example, the rib 122 and the seating groove 1421 can be arranged in a ring shape around the lens barrel 141. Meanwhile, a plurality of guiding parts 124 can be arranged around the rib 122.

[0079] The rib 122 can be formed by bending a part of the metal plate 120, and since the rib 122 is arranged in a ring shape, end processing is easier compared to other shapes, so that the rib 122 can be easily manufactured.

[0080] In one embodiment, the camera module 140 can be stably mounted on the metal plate 120 through the guiding part 124 and the rib 122. In particular, the lens barrel 141 can be arranged inside the rib 122.

[0081] In this case, the main body 142 can be arranged to be surrounded by a plurality of guiding parts 124, and the end of the rib 122 can be seated in the seating groove 1421. The camera module 140 can be stably mounted in the metal plate 120 through the dual structure of the guiding part 124 and the rib 122 to maintain the mounting position.

[0082] In one embodiment, when the camera module 140 is mounted on the display device, the mounting position is determined by the guiding part 124 and the rib 122. Therefore, the worker simply assembles the camera module 140 into the guiding part 124 and the rib 122 without separately setting the arrangement position of the camera module 140. Therefore, the camera module 140 can be easily mounted on the display device.

[0083] When the guiding part 124 and the rib 122 are formed on the metal plate 120, methods such as casting, die-casting, or injection molding can be used. However, these methods may require a separate mold frame.

[0084] In addition, compared with the overall size of the display device, the camera module 140 can be very small, and the guiding part 124 and the rib 122 for mounting the camera module 140 can also be provided in very small sizes. Therefore, it is difficult to form the very small guiding part 124 and the rib 122 on the metal plate 120 by methods such as casting, and defects are likely to occur.

[0085] Hereinafter, an example in which the guiding part 124 and the rib 122 are formed by using bending processing, which is simpler than methods such as casting and has a lower defect rate, will be described in detail.

[0086] The metal plate 120 may be provided with a forming hole 123 for forming the guiding part 124 in the metal plate 120, and the guiding part 124 is formed by bending a portion adjacent to the forming hole 123.

[0087] Since the metal plate 120 is made of a metal having excellent malleability and ductility, the guiding part 124 and the rib 122 having a relatively small volume can be formed by bending processing.

[0088] Referring to Figure 5 , the forming hole 123 for forming the guiding part 124 can be formed at a designed position on the metal plate 120 by stamping. For example, a plurality of forming holes 123 can be formed in a "U" shape at spaced-apart positions to surround the second through-hole 121 or the primary through-hole 121'.

[0089] In this case, a second area 124' that will subsequently become the guiding part 124 can be formed by the forming hole 123. In the bending process, the second area 124' can be bent to protrude forward, and thus, the second area 124' can become the guiding part 124.

[0090] Such bending processing can be performed manually by a worker or using an automatic bending machine.

[0091] The rib 122 can be formed by bending a portion of the metal plate 120 that contacts the second through-hole 121. As the rib 122 having a relatively small diameter is formed by bending, the second through-hole 121 can be formed to have an enlarged diameter.

[0092] Referring to Figure 5 , first, a preliminary through-hole 121' having a relatively small diameter can be formed at a designed position on the metal plate 120 by stamping. A first area 122' that is set to be annular and will become the rib 122 in the future can exist at a position surrounding the preliminary through-hole 121' of the metal plate 120.

[0093] Through bending, the first region 122' can protrude forward, so that the first region 122' can become the rib 122. For example, when pressure is applied by inserting a rod-shaped tool with a diameter the same as or very similar to that of the second through-hole into the preliminary through-hole 121', the first region 122' can protrude to form the rib 122.

[0094] In this case, as the rib 122 is formed by bending, the primary through-hole 121' with a relatively small diameter can have an enlarged diameter, and thus become the second through-hole with a relatively large diameter.

[0095] Since the metal plate 120 has excellent malleability and ductility, even when such bending is performed, the first region 122' of the metal plate 120 can be smoothly deformed without breaking, and thus become the rib 122.

[0096] The guiding part 124 and the rib 122 can be easily formed by stamping and bending according to the above method.

[0097] In one embodiment, the guiding part 124 and the rib 122 can be formed on the metal plate 120 by stamping and bending, and a separate mold frame for casting, die-casting, injection molding, etc. may not be used.

[0098] Therefore, the process for forming the guiding part 124 and the rib 122 can be easy, the manufacturing process of the display device can be simplified, and the manufacturing cost can be reduced. In addition, when the guiding part 124 and the rib 122 with a relatively small volume in the entire display device are formed, the defect rate can be significantly reduced compared with methods such as casting.

[0099] Regardless of which part of the display module 110 it is set in, the camera module 140 can increase the area efficiency and space efficiency of the display device. However, the camera module 140 can be set at a position overlapping with the printed circuit board 130, for example.

[0100] Specifically, a hole for inserting the lens barrel 141 can be formed in the printed circuit board 130, and the lens barrel 141 can be placed in the hole to be set at a position overlapping with the printed circuit board 130.

[0101] When the camera module 140 is set 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 compared with the case where the camera module 140 is not set on the printed circuit board 130, the cable 126 can be shortened, thereby improving the space efficiency in the display device.

[0102] Hereinafter, the structure in which the camera module 140 is disposed on the printed circuit board 130, that is, the structure in which the camera module 140 and the printed circuit board 130 are disposed to overlap each other, will be described in detail.

[0103] Figure 7 FIG. is a partial view showing a portion of the printed circuit board 130 in which a third through hole 131 is formed according to an embodiment. Figure 8 FIG. is a partial view showing a state in which the metal plate 120 and the printed circuit board 130 are coupled.

[0104] The printed circuit board 130 may include a third through hole 131 and an insertion hole 132 to arrange the camera module 140. The third through hole 131 may be formed at a position corresponding to the second through hole 121, and the lens barrel 141 may be disposed therein.

[0105] The lens barrel 141 may be disposed in the third through hole 131 to pass through the printed circuit board 130, and may also pass through the first through hole 111 and the second through hole 121 to face the display device and capture an image.

[0106] The rib 122 may be inserted into the third through hole 131. The rib 122 may be provided to protrude forward through the third through hole 131, and the rib 122 may be assembled into the seating groove 1421 of the main body 142. With this structure, the camera module 140 and the metal plate 120 may be coupled in a case where the printed circuit board 130 is disposed between the metal plate 120 and the camera module 140.

[0107] The insertion hole 132 may be formed at a position corresponding to the guide portion 124, and the guide portion 124 may be inserted therein. The number of the insertion holes 132 may be equal to or less than the number of the guide portions 124. That is, when a groove 133, which will be described below, is formed in the printed circuit board 130 and the guide portion 124 is inserted therein, the number of the insertion holes 132 may be less than the number of the guide portions 124.

[0108] For example, similar to the case where the rib 122 surrounds the second through hole 121, the insertion hole 132 may be provided to surround at least a part of the third through hole 131.

[0109] By inserting the guide portion 124 into the insertion hole 132, the printed circuit board 130 may be stably disposed at a designed position on the metal plate 120. In addition, the guide portion 124 passing through the insertion hole 132 may protrude forward, and the main body 142 may be assembled into the guide portion 124 and supported by the guide portion 124. With this structure, the camera module 140 and the metal plate 120 may be coupled in a state where the printed circuit board 130 is interposed therebetween.

[0110] The printed circuit board 130 may include a groove 133 separate from the insertion hole 132 to dispose the camera module 140. An end portion of the printed circuit board 130 may be recessed to form the groove 133, and the guiding portion 124 may be inserted into the groove 133.

[0111] The guiding portion 124 needs to be provided at an end portion of the printed circuit board 130 according to the disposition position of the camera module 140 on the printed circuit board 130. In the case of such a structure, the groove 133 may be formed at the end portion of the printed circuit board 130, and some of the plurality of guiding portions 124 may be inserted into the groove 133 to protrude forward.
