ABSTRACT:
A structure of direct type backlight module with high uniform emitting light explores a design of lenticular lens of diffusing plate. The lenticular lens is against the central location of light source, where the light of lamp is scattered and the curvature of said lenticular lens far away light source is enlarged, then to reduce the scatter effect and achieve uniformity. The other lenticular lens also can be designed for light location and distance. Each lenticular lens is against light location, and incident light can be reflected through the angle of microstructure surface at the entrance facet, but farther location can be resulted in total refraction due to large inclined angle, and diminishing the transmission light of light source then influencing the uniformity, finally reducing total reflection of wide angle.
