AI Technical Summary
The existing vehicle display has poor heat dissipation effect in the IC area and cannot meet the heat dissipation needs in the core area, resulting in a higher temperature rise in the IC area.
A thermally conductive film is used as a cooling structure. The thermally conductive film is connected to the metal shell, covered on the IC area, and a heat-insulating film is pasted on the thermally conductive film to insulate heat conduction onto the glass cover plate.
The heat in the IC region is directed to the housing through a thermally conductive film, which reduces the heat around the IC region, and prevents heat from being transmitted to the glass cover plate through a thermally insulating film, achieving uniformity between the IC region and other areas.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of vehicle-mounted display screens, and specifically relates to a novel display screen IC zone heat dissipation structure. Background Art
[0002] The current development trend of vehicle-mounted display screens is large screens and high brightness. In summer, due to the high ambient temperature, high brightness of the display screen, and high heat generation, the display screen feels very hot after it is turned on. The temperature rise of the display screen is mainly composed of two parts: the temperature rise caused by the heat of the display backlight LED and the temperature rise caused by the power of the display IC. For conventional displays, the heat dissipation of the backlight LED is dissipated through the backlight shell, but the heat in the IC area will be directly conducted to the cover plate, causing the temperature rise of the IC area to be about 3 degrees higher than other areas of the display screen.
[0003] The patent number is 202111353009.7, and a public specification published on December 12, 2023 discloses a display screen heat dissipation assembly, a display screen, and a control method for the display screen heat dissipation assembly. The display screen heat dissipation assembly includes a mounting seat, a light source assembly, and a heat dissipation adjustment structure, wherein the mounting seat forms a mounting cavity with an opening at one end, and the light source assembly is arranged in the mounting cavity. The light source assembly has a relative light-emitting surface and a heat dissipation surface, and the light-emitting surface is arranged corresponding to the open end of the mounting seat. A heat dissipation cavity is formed between the light source assembly and the mounting seat, and a heat dissipation port is provided on the side wall of the heat dissipation cavity. The heat dissipation adjustment structure includes a heat dissipation cover movably arranged at the heat dissipation port, and a driving assembly arranged on the mounting seat. The driving assembly drives the heat dissipation cover to open or close the heat dissipation port. The heat dissipation port is opened or closed by the movement of the heat dissipation cover, which can not only ensure the heat dissipation of the display screen, but also prevent impurities from entering the display screen, thereby effectively protecting the electrical components in the display screen and improving the service life of the display screen.
[0004] In the prior art, the heat dissipation structure is relatively large and is not suitable for vehicle-mounted display screens. In addition, the vehicle-mounted display screens have poor heat dissipation effect on the IC area and cannot meet the heat dissipation requirements of the core area. Utility Model Content
[0005] The utility model aims to provide a novel display screen IC zone heat dissipation structure which has good IC zone heat dissipation effect.
[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a new display screen IC zone heat dissipation structure, including a display screen, a shell arranged on the display screen and a glass cover plate arranged on the display screen, the IC zone is arranged on one side of the display screen, and a cooling structure connected to the shell is provided on the IC zone, and the shell is a metal shell.
[0007] The cooling structure is a heat-conducting film arranged on the IC area, and the heat-conducting film is connected to the housing.
[0008] The thermal conductive film covers the IC area, and the thermal conductive film is attached to the surface of the IC area.
[0009] A flat plate is provided on the side of the shell, and the heat-conducting film is attached to the flat plate.
[0010] The glass cover plate is pressed onto the surface of the display screen, and the heat conductive film is arranged between the glass cover plate and the IC area.
[0011] The glass cover plate is provided with a heat insulation film.
[0012] The thermal insulation film is arranged between the thermal conductive film and the glass cover plate, and the thermal insulation film covers the portion of the thermal conductive film attached to the IC area.
[0013] The technical effect of the utility model is as follows: the IC is connected to the backlight housing through a heat-conducting film with a back adhesive, and the back adhesive can conduct heat. Since the backlight housing is made of metal material, the heat of the IC is transferred to the housing through the heat-conducting film, thereby reducing the heat around the IC area; a layer of heat-insulating film is pasted on the heat-conducting film, so that the heat conducted by the IC is isolated by the heat-insulating film and cannot be conducted to the cover plate, so that in the touch area of the cover plate, the temperature of the IC position is consistent with other areas, and the temperature is uniform.
