Abstract
A backlight module includes a mold frame, a light guide plate, a light bar light source, and an optic film. The light guide plate, the light source, and the optic film are disposed in the mold frame. The light source is arranged between the light guide plate and the mold frame. The optic film and the light guide plate are stacked on each other. The backlight module includes a heat dissipation frame that includes first, second, and third heat dissipation walls. The third heat dissipation wall is opposite to the first heat dissipation wall and the second heat dissipation wall is connected to the first and third heat dissipation walls. An end of the mold frame at which the light source is arranged is received between the first and third heat dissipation walls and the mold frame is in tight engagement with the second heat dissipation wall.
