Abstract
A backlight module includes a drive substrate and a plurality of light sources. The drive substrate has a first side on which the plurality of light sources are provided at intervals. The backlight module further includes a first heat dissipation layer. The first heat dissipation layer is a transparent film and disposed on the first side of the drive substrate and located between adjacent light sources, to be directly in contact with the light sources, so as to block the light sources and absorb the heat of the light source and radiate heat, which is beneficial for reducing or eliminating the thermal coupling between adjacent light sources and helping the first side of the drive substrate to dissipate heat, so that the designed backlight module has better thermal stability and longer service life.
