Abstract
A light guide plate includes a light incident surface, a light output surface, a bottom surface opposite to the light output surface, and a plurality of dots formed on the bottom surface. Each dot includes a first curved surface, a second curved surface and two flat surfaces separately interconnecting the first curved surface and the second curved surface. The first curved surface is configured for perpendicularly reflecting light towards the light output surface. The second curved surface is configured for scattering and reflecting light back into the light guide plate. The two flat surfaces are configured for diverging light to lateral sides of an original path.
Claims8
A light guiding plate, comprising:
- a light incident surface;
- a light output surface;
- a bottom surface opposite to the light output surface;
- and
- a plurality of dots formed on the bottom surface, wherein each dot comprises a first curved surface, a second curved surface and two flat surfaces interconnecting the first curved surface and the second curved surface, lights which are directed to the first curved surface are reflected by the first curved surface to perpendicularly enter the output surface, lights which are directed to the second curved surface are scattered and reflected by the second curved surface to the inner of the light guiding plate, lights which are directed to the two flat surfaces are reflected and scattered by the two flat surfaces to lateral sides of the original incident pathway of the lights which enter the two flat surfaces.
