ABSTRACT:
A direct backlight module is disclosed, which comprises: a frame; at least a light source, being arranged in the frame; a diffuser, being disposed over the frame; and at least an optical film, being disposed over the diffuser, comprising a substrate having a top surface and a bottom surface; wherein a diffusion unit and a collimation unit are formed on the top surface while using the diffusion unit for diffusing light incident to the bottom surface and the collimation unit for collimating light incident to the bottom surface. The direct backlight module of the invention is capable of enhancing luminous efficiency, and further, it has a comparatively simple structure so that the manufacturing cost of the optical film can be reduced.
