Description

Technical Field

[0001] The present disclosure relates to a display device and a vehicle having the same, wherein the display device improves waterproof performance of the display device by the shape of a rear cover covering a printed circuit board in the display device mounted on the vehicle, and reduces the thickness of the display device while ensuring rigidity by a cover member covering a backlight unit. Background Art

[0002] The central instrument panel display of the vehicle can display various visual information about the vehicle. Such a display device can also be installed in the dashboard of the vehicle arranged in front of the driver's seat and the front passenger seat, and provide various convenient information such as navigation, vehicle management and operation, Internet and entertainment.

[0003] The display device processes signals via a printed circuit board (PCB) located on a rear surface of the display panel to display images.

[0004] Typically, the printed circuit board is arranged parallel to the rear surface of the display panel. In this case, there is a risk that the printed circuit board may be damaged by moisture or water that may flow into the gap of the display device.

[0005] For example, when a vehicle occupant operates the display device while drinking a beverage, the beverage may flow into a gap of the display device, thereby causing damage to the printed circuit board.

[0006] Therefore, there is a need for an apparatus for improving waterproof performance of a display device so that a printed circuit board can be protected from moisture or water that may flow into a gap of the display device.

[0007] Furthermore, in recent years, the size of a display device mounted on a vehicle has been increasing, and therefore, there is a need for an apparatus that reduces the thickness of the display device while ensuring rigidity.

[0008] In addition, the electronic device emits electromagnetic waves between the electronic components mounted on the printed circuit board, thereby causing electromagnetic interference (EMI). Such EMI causes the electronic device to malfunction or has a negative impact on the human body. In particular, when the operating frequency of the electronic device increases to a range of tens of MHz to several GHz, the EMI problem becomes more serious.

[0009] Therefore, even in the case where the display device is mounted on a vehicle, a device capable of solving the above-mentioned EMI noise problem is required. Utility Model Content

[0039] Figure 1 1 is an exploded perspective view showing a display device 10 which is generally mounted on a vehicle.

[0040] like Figure 1 As shown, the conventional display device 10 includes: a display module 11 ; a printed circuit board 12 connected to the display module 11 ; a bracket 13 covering the display module 11 and the printed circuit board 12 ; and a back cover 14 .

[0041] In the case of a conventional display device 10, a printed circuit board 12 is disposed parallel to the rear surface of the display module 11. In addition, a bracket 13 covering the display module 11 and the printed circuit board 12 is generally made of aluminum as a configuration for shielding and heat dissipation, and a rear cover 14 is generally made of plastic.

[0042] However, when the printed circuit board 12 is disposed in parallel with the rear surface of the display module 11 as described above, there is a problem that the printed circuit board 12 may be damaged by moisture that may flow into the gap of the display device 10. Therefore, it is necessary to improve the watertightness by protecting the printed circuit board 12 from moisture that may flow into the gap of the display device 10.

[0043] In addition, as described above, in order to reduce the thickness of the display device 10, it is necessary to omit the configuration when the display device 10 becomes larger. If the bracket 13 covering the display module 11 and the printed circuit board 12 can be omitted, the thickness of the display device 10 can be reduced.

[0044] Figure 2 is an exploded perspective view showing a display device 100 according to an embodiment of the present disclosure. Figure 3 is a diagram illustrating a shape in which a printed circuit board 130 is covered by a cover bracket 121 of a back cover 120 in a display device 100 according to an embodiment of the present disclosure. Figure 4 It shows Figure 2 A magnified view of area A, and Figure 5 It shows Figure 2 Magnified view of area B.

[0045] The display device 100 according to an embodiment of the present disclosure may include a display module 110, a back cover 120, a printed circuit board 130, and a bottom cover 140. The back cover 120 may cover the display module 110 while surrounding the side surface and the rear surface of the display module 110. In addition, a cover bracket 121 may be included, which is formed in a manner of protruding from the lower side of the rear surface of the back cover 120. In addition, the bottom cover 140 may be coupled to the cover bracket 121, and the bottom cover 140 may be fixed and coupled to the cover bracket 121 by a coupling groove 122 formed in the side surface of the cover bracket 121. In addition, the cover bracket 121 and the bottom cover 140 may be embedded in a mounting portion of a vehicle. As shown in FIG. Figure 2 and Figure 3 As shown, the rear cover 120 may protrude from the rear surface to form a right angle and have an "L" shape by the cover bracket 121. In addition, one surface of the printed circuit board 130 may be covered by the cover bracket 121, and the bottom cover 140 may be coupled to the cover bracket 121 to cover the other surface of the printed circuit board 130.

[0046] That is, the display device 100 according to one embodiment of the present disclosure may cover the printed circuit board 130 with the bottom cover 140 and the cover bracket 121 of the back cover 120 , and the printed circuit board 130 may be positioned perpendicular to the rear surface of the back cover 120 .

[0047] Thus, the display device 100 according to one embodiment of the present disclosure may improve the watertightness of the display device 100 by protecting the printed circuit board 130 from moisture that may flow into the gap of the display device 100 .

[0048] In addition, in the display device 100 according to an embodiment of the present disclosure, the back cover 120 may include a high-strength composite material having conductivity. This is to reduce EMI noise through the back cover 120 including the conductive material, because as described above, electromagnetic waves are emitted between electronic components mounted on the printed circuit board 130 and may cause electromagnetic interference (EMI).

[0049] In addition, the display device 100 according to one embodiment of the present disclosure may omit Figure 1 The bracket 13 shown in FIG. 1 is provided to reduce the thickness of the display device 100 as described above, and the back cover 120 may include a high-strength composite material having greater rigidity than a plastic material.

[0050] Furthermore, the display device 100 can thereby be stably mounted on the vehicle and can be advantageous against damage caused by external force that may be applied to the display device 100. Therefore, the rigidity of the display device 100 can be ensured by the back cover 120 including the high-strength composite material.

[0051] Furthermore, in the display device 100 according to one embodiment of the present disclosure, the bottom cover 140 is coupled to the cover bracket 121 and covers the other surface of the printed circuit board 130. And, the bottom cover 140 may be formed of a metal material such as aluminum for shielding and heat dissipation.

[0052] In addition, the printed circuit board 130 may be connected to the display module 110 in the display device 100 according to one embodiment of the present disclosure, and in this case, the connection cable 131 of the printed circuit board 130 may pass through a hole provided in the back cover 120 to be connected to the display module 110 .

Here, the backlight unit 113 may be a device that provides a light source to the display panel 111 by forming a uniform surface light source.

[0054] The cover member 114 may be coupled to the rear surface of the glass 112 and may cover the backlight unit 113. In addition, upper and lower portions of the cover member 114 may be bent toward the rear surface of the glass 112. Here, the display module 110 may include a fixing member 115 positioned inside the cover member 114 to fix the display panel 111 to the cover member 114.

[0055] That is, because the upper and lower portions of the cover member 114 can be bent toward the rear surface of the glass 112 and the fixing member 115 can be located inside the cover member 114 , the upper and lower surfaces of the cover member 114 can be directly connected to the rear surface of the glass 112 through the adhesive member 150 .

[0056] Therefore, according to one embodiment of the present disclosure, the display device 100 can reduce the thickness of the display device 100 through such a structure, that is, in which the cover member 114 covering the backlight unit 113 is directly connected to the rear surface of the glass 112 and the fixing member 115 fixing the display panel 111 is located on the inner side of the cover member 114.

[0057] Furthermore, in the display device 100 according to one embodiment of the present disclosure, the cover member 114 may include a high-strength composite material having stronger rigidity than a plastic material, thereby ensuring the rigidity of the display device 100 .

[0058] In addition, if Figure 5As shown, the cover member 114 may include a partition 114a protruding from the lower side of its front surface, and the light source 113a of the backlight unit 113 may be positioned on the upper surface of the partition 114a. Here, according to one embodiment of the present disclosure, the light source 113a may include a light emitting diode (LED). That is, a plurality of LEDs may be arranged in a row on the upper surface of the partition 114a to directly apply light to the front surface of the display panel 111.

[0059] In summary, the display device and the vehicle having the same according to the present disclosure can improve the waterproof performance of the display device by covering the printed circuit board by a cover bracket formed to protrude from the rear cover and a bottom cover coupled to the cover bracket. In addition, a cover member covering the backlight unit is coupled to the glass and a fixing member fixing the display panel is positioned inside the cover member, thereby reducing the thickness of the display device while ensuring rigidity.

[0060] The above detailed description should be construed in all aspects as illustrative rather than restrictive. The scope of the present disclosure should be determined by reasonable interpretation of the appended claims, and all changes that come within the equivalent range of the present disclosure are intended to be included in the scope of the present disclosure.
