Abstract:
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.
