Abstract
The present invention provides a backlight module, which includes: a backplane (), a light guide plate () arranged in the backplane (), a backlight source () mounted on the backplane (), and a heat dissipation film () mounted on the backplane (). The heat dissipation film () is made of graphene and has a thickness of 0.01-0.05 mm. The backlight module of the present invention provides includes a graphene-made heat dissipation film formed on a backplane to effectively improve the heat dissipation performance of the backlight module, allowing thermal energy to be uniformly distributed on the entire surface of the heat dissipation film in the plane direction to eliminate localized hot spots. Further, the graphene material is light-weighted so that addition of the heat dissipation film made of graphene does not significantly increase the weight of the backlight module.
