▎ 摘　　要

NOVELTY - The module has a driving substrate (120) and light sources (140). The driving substrate has a first side surface. The light sources are arranged at intervals on the first side surface of the driving substrate. A first heat dissipation layer (110) is arranged on the first side surface of the driving substrate and between the adjacent light sources. The first heat dissipation layer is a transparent film layer. The first heat dissipation layer comprises a graphene coating. An optical film is arranged on the side of the first heat dissipation layer away from the driving substrate. USE - Backlight module for display device (claimed). ADVANTAGE - The backlight module is used to reduce or eliminate the thermal coupling between adjacent light sources and help the first side of the driving substrate to dissipate heat, so that the thermal stability of the designed backlight module is better and the service life is shortened. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for forming a backlight module. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the backlight module.
