Abstract:
1. A backlight module, comprising a light guide plate and light sources, where said light guide plate comprises lateral incident faces, an exit face that joins the lateral incident faces, and an underside that corresponds to the exit face; said light sources each comprising an emitting surface, being disposed near one side of one lateral incident face of said light guide plate, and corresponding to the lateral incident face of said light guide plate with the emitting surface, characterized in that: the backlight module further comprises diffusion strips, where the diffusion strips each is disposed in between one lateral incident face of said light guide plate and the emitting surface of said light source, and the diffusion strip being provided with through holes, where the locations of the through holes correspond to the locations between adjacent light emitting diodes of said light source, and the light rays emitted from the emitting surface of said light source passing the through holes of the diffusion strip and diffusing into said light guide plate; wherein the backlight module further comprises a diffusion plate, where the diffusion plate is located on said light guide plate, said light guide plate and the diffusion plate being planar, and the diffusion plate being disposed directly on said light guide plate; wherein the diffusion strips connect to the diffusion plate, the diffusion strips and the diffusion plate are shaped into one piece, and the diffusion strips are formed by bending the two lateral ends of the diffusion plate downward followed by an extension.
