Abrégé
(EN)

The present invention provides a backlight module, which includes a backplane and a backlight source fixed to the backplane through fusion. The backplane includes a first backplane segment and a second backplane segment coupled to the first backplane segment. The present invention provides a backlight module, which includes a backplane that is formed by combining a material of high thermal conductivity and a material of high strength. The backplane has a great strength, excellent thermal conductivity, and low cost so as to reduce the overall cost of the entire backlight module. Further, a backlight source is fixed, through fusion, to the backplane made of a material of high thermal conductivity so that the backlight source and the backplane are connected in a gap-free manner to further improve the performance of thermal conduction of the backlight module.
