摘要： An optical diffusion device applied in a backlight module includes a plate. Multiple light sources are disposed on one side of the plate. Multiple optical microstructures provided with a longer axis and a shorter axis are disposed on the plate. The longer axis of each optical microstructure is approximately arranged in parallel with a direction extending from the light source, or, in other words, the shorter axis is arranged approximately crossing the direction extending from the light source. A diffusion effect is provided to each light source through the shorter axis of the optical microstructure to increase optical radiant energy among the light sources and to eliminate the dim and dark regions among the light sources for increasing general luminance of the backlight module.

摘要： A composite diffuser structure includes a transparent layer having a light-entering surface and a light-emitting surface, a lenticular structure having a plurality of lenticular lens formed on the light-emitting surface, and a plurality of refection structures located on the light-entering surface. Each of the lenticular lenses has a first width. There is an opening between two adjacent reflection structures. Each of the openings has a second width. Thereby, the light beam enters into the transparent layer via the opening to increase the light efficiency. By using the diffuser layer located above the lenticular structure, the view angle can be adjusted.

摘要： 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.
