NOVELTY - The utility model claims a vehicle-mounted display screen based on graphene heat-conducting, comprising a glass cover plate a liquid crystal panel a backlight plate, a die-casting cover and LED lamp strip, LED lamp strip is set on the inner side wall of the die-casting cover; the graphene heat conducting film is adhered on the inner wall surface of the die-casting rear cover; LED lamp strip is adhered on the graphene heat conducting film. Preferably, the graphene heat conducting film and LED lamp strip are made of non-base material heat conducting double faced adhesive tape. The beneficial effects of the utility model are as follows: using high heat characteristics of the graphite, the heat of the LED strip is quickly conducted and dispersed to the whole inner wall surface of the die-casting back cover, and fully exerting the heat dissipation structure of the die-casting cover to quickly radiate the heat to the external environment, so as to eliminate the heat concentration phenomenon, reducing the temperature of the LED eliminating the failure LED trouble, improving uniformity of screen temperature distribution of the display screen, reducing the temperature difference between the highest temperature and different areas of each area, the screen temperature distribution requirement of satisfy product design, and high productivity
