Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle display, and more specifically, to a vehicle display screen with high-efficiency heat dissipation. Background Technology
[0002] Existing in-vehicle displays generally adopt touch control solutions. Their functions are driven by chips located at the edge of the display area. These chips are usually located under the cover plate. They generate a lot of heat when they are working. Since the chip is located close to the edge of the visible area of the display, users' fingers are likely to touch the corresponding cover plate surface when operating, thus perceiving local overheating, which affects the user experience. In addition, long-term overheating will also accelerate the aging of the display module and shorten its lifespan. Utility Model Content
[0003] The purpose of this invention is to provide a vehicle display screen with high-efficiency heat dissipation, which can quickly conduct heat from the edge of the display module to the frame, improve the user experience, and extend the service life of the display module.
[0004] A high-efficiency heat dissipation vehicle display includes a display module, a frame, and a flexible heat-conducting component. The display module is disposed inside the frame, and a gap exists between one side of the display module and the frame. The flexible heat-conducting component fills the gap and is in close contact with the display module and the frame to conduct heat from the display module to the frame.
[0005] In the above technical solution, the flexible thermal conductive component fills the gap between the display module and the frame, forming an efficient heat conduction path. This allows heat from the edge of the display module to be quickly diffused to the metal frame, effectively reducing the surface temperature of the touch area and preventing users from experiencing localized overheating. Passive heat dissipation through the large-area heat dissipation structure of the frame significantly reduces heat accumulation inside the display module, thereby delaying the aging of optical materials and extending the overall lifespan of the display. This solution eliminates the need for additional active cooling components, achieving stable heat dissipation solely through optimized structural design. It balances the lightweight and reliability requirements of automotive equipment, improving the user touch experience and product durability.
[0006] Furthermore, the display module includes a display panel, a flexible circuit board, and a thermally conductive tape. A heating element is provided on the first surface of the display panel. One end of the flexible circuit board is disposed adjacent to the heating element, and the other end extends outward from the display panel. One end of the thermally conductive tape is attached to the second surface of the display panel and its position corresponds to the heating element, and the other end is bonded to the flexible circuit board.
[0007] In the above technical solution, thermally conductive tape is used to connect the display panel and the flexible circuit board, so that the heat generated by the heat-generating element can be extended to the outer space of the display panel through the flexible circuit board for heat dissipation, thereby expanding the heat dissipation surface area and effectively reducing the temperature of the user contact area.
[0008] Furthermore, the heating elements are arranged on the first surface in the region near the flexible heat-conducting element.
[0009] In the above technical solution, the heating elements are concentrated in the area close to the flexible heat-conducting component, which shortens the distance of heat conduction to the frame and improves the heat dissipation speed.
[0010] Furthermore, the heating element is a control chip.
[0011] Furthermore, it also includes a cover plate, which is connected to the frame and covers the heating element.
[0012] In the above technical solution, the cover plate covers the heating element, and the heat of the heating element is quickly dissipated through the heat dissipation structure, which can reduce the surface temperature of the contact area of the cover plate.
[0013] Furthermore, the outline shape of the thermally conductive tape is adapted to the outline shape of the flexible circuit board.
[0014] In the above technical solution, the thermally conductive tape is adapted to the contour of the flexible circuit board and can cover the surface of the flexible circuit board, thereby increasing the heat dissipation area and improving the heat dissipation efficiency.
[0015] Furthermore, the frame has multiple heat dissipation holes on its sidewall corresponding to the flexible heat-conducting component.
[0016] In the above technical solution, the heat dissipation holes are opened on the side wall of the frame corresponding to the heat-conducting component, which can carry away heat through the air and accelerate the dissipation of heat into the environment.
[0017] Furthermore, the flexible thermal conductive element is graphene foam.
[0018] In the above technical solution, graphene foam has both flexible bonding and high thermal conductivity, and maintains close contact with the display module and frame even under vehicle vibration conditions, ensuring long-term stable heat dissipation performance.
[0019] Compared with existing technologies, the advantages of this invention are as follows: The flexible heat-conducting component fills the gap between the display module and the frame, forming an efficient heat conduction path. This allows heat from the edge of the display module to be quickly diffused to the metal frame, effectively reducing the surface temperature of the touch area and preventing users from experiencing localized overheating during operation. Passive heat dissipation through the large-area heat dissipation structure of the frame significantly reduces heat accumulation inside the display module, thereby delaying the aging of optical materials and extending the overall lifespan of the display screen. This solution eliminates the need for additional active heat dissipation components, achieving stable heat dissipation solely through optimized structural design. It balances the lightweight and reliability requirements of automotive equipment, improving the user touch experience and product durability. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0027] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0028] Please refer to Figures 1 to 4In a preferred embodiment, the high-efficiency heat dissipation vehicle display screen of the present invention mainly includes a display module 1, a frame 2, and a flexible heat-conducting component 3. The display module 1 is disposed inside the frame 2, and there is a gap between one side of the display module 1 and the frame 2. The flexible heat-conducting component 3 fills the gap and is in close contact with the display module 1 and the frame 2 so as to conduct the heat of the display module 1 to the frame 2.
[0029] For example, both the frame 2 and the display module 1 are rectangular. The frame 2 can be made of metal, and the display module 1 can be an existing direct-lit backlight display module 1. The length of the display module 1 matches the length of the frame 2, and the width of the display module 1 is smaller than the width of the frame 2, thus forming a gap between one side of the display module 1 and the frame 2. In this embodiment, the gap is located above the display module 1. The flexible heat-conducting component 3 fills the gap between the display module 1 and the frame 2, forming an efficient heat conduction path, which quickly diffuses the heat from the edge of the display module 1 to the metal frame 2, effectively reducing the surface temperature of the touch area and preventing the user from perceiving local overheating during operation. Passive heat dissipation through the large-area heat dissipation structure of the frame 2 significantly reduces the accumulation of heat inside the display module 1, thereby delaying the aging of optical materials and extending the overall lifespan of the display screen. This solution does not require the addition of active heat dissipation components, but achieves stable heat dissipation only through optimized structural design, taking into account the lightweight and reliability requirements of automotive equipment, improving the user touch experience and product durability.
[0030] The display module 1 includes a display panel 11, a flexible circuit board 12, and a thermally conductive tape 13. A heating element 113 is disposed on a first surface 111 of the display panel 11. One end of the flexible circuit board 12 is disposed adjacent to the heating element 113, and the other end extends outward from the display panel 11. One end of the thermally conductive tape 13 is attached to the second surface 112 of the display panel 11 and positioned corresponding to the heating element 113, while the other end is bonded to the flexible circuit board 12. Exemplarily, the first surface 111 and the second surface 112 face opposite directions. The first surface 111 has a display area, and the heating element 113 is disposed at the edge of the display area. The flexible circuit board 12 extends outward from the display panel 11. It is understood that the flexible circuit board 12 is connected to a main control circuit board (not shown) for signal transmission to the display panel 11. The thermally conductive tape 13 can be made of existing thermally conductive materials. By using the thermally conductive tape 13 to connect the display panel 11 and the flexible circuit board 12, the heat generated by the heating element 113 is extended to the outer space of the display panel 11 through the flexible circuit board 12 for heat dissipation, thereby expanding the heat dissipation surface area and effectively reducing the temperature of the user contact area.
[0031] Heating elements 113 are arranged on the first surface 111 in the region near the flexible heat conductor 3. Concentrating the heating elements 113 in the region near the flexible heat conductor 3 shortens the distance heat is conducted to the frame 2, thus improving heat dissipation speed. In this embodiment, the heating element 113 is a control chip; in other possible embodiments, the heating element 113 can be other electronic components that generate heat during operation.
[0032] The high-efficiency heat dissipation vehicle display screen of this invention also includes a cover plate 4, which is connected to the frame 2 and covers the heat-generating element 113. The cover plate 4 covers the heat-generating element 113, and the heat dissipation structure quickly dissipates the heat of the heat-generating element 113, thereby reducing the surface temperature of the contact area of the cover plate 4.
[0033] In this embodiment, the outline shape of the thermally conductive tape 13 is adapted to the outline shape of the flexible circuit board 12. The thermally conductive tape 13, being adapted to the outline of the flexible circuit board 12, can cover the surface of the flexible circuit board 12, thereby increasing the heat dissipation area and improving heat dissipation efficiency.
[0034] Multiple heat dissipation holes 21 are provided on the side wall of the frame 2 corresponding to the flexible heat-conducting component 3. These heat dissipation holes 21, located on the side wall of the frame 2 at the positions corresponding to the heat-conducting component, allow heat to be carried away by air, accelerating heat dissipation into the environment. In this embodiment, the heat dissipation holes 21 are located at the upper end of the frame 2, utilizing the principle that hot air has a low density and tends to rise, which is beneficial for accelerating heat dissipation.
[0035] In this embodiment, the flexible thermal conductive element 3 is graphene foam. Graphene foam combines flexible adhesion with high thermal conductivity, maintaining close contact with the display module 1 and the frame 2 even under vehicle vibration conditions, ensuring stable and long-lasting heat dissipation performance. In other possible embodiments, the flexible thermal conductive element 3 can be any existing flexible material with thermal conductivity.
