摘要:
The present invention discloses an optical film with array of microstructures, having a first optical surface and a second optical surface for receiving an incident light. The optical film comprises at least a transparent microstructure formed on the first optical surface, wherein the microstructure further comprises: a first side for scattering the incident light; and a second side for collimating the incident light.

The present invention discloses a light modulation element, having a first optical surface and a second optical surface receiving an incident light, the light modulation element comprising: at least a transparent diffusion unit, for scattering the incident light, each being placed on the first optical surface; and at least a transparent collimation unit, for collimating the incident light, each being formed on top of the diffusion unit.
摘要:
An apparatus for homogeneously distributing lights includes a light guide plate, an incidence microstructure and an emergence microstructure. The incidence microstructure is arranged on a surface of the light guide plate and opposite to a light source. The emergence microstructure is arranged on a surface of the light guide plate opposite to the incidence microstructure. The lights emitted by the light source pass through said apparatus thereby being homogenously distributed. Thus the manufacture costs are lowered, and the light source utilization ratio is increased.
摘要:
A light guide plate and method for fabricating the same are proposed. An injection molding process is performed to form at least an arc-shaped first opening portion on the light guide plate, so that a concave lens structure is formed on an edge of the first opening portion to be in line with a light source. By such arrangement, the concave lens structure can direct light and achieve a uniform light dispersion effect.
