Patent ID: 8305527

Claim:
A color separation system, comprising: a backlight source, being highly collimated and used for providing an incident beam; a color separation module, formed with a first color separation film configured with a first light incident surface and a first light emergence surface; and a beam splitting module, being configured with at least one beam splitting plate and a liquid crystal layer; wherein, the first light incident surface, being configured with periodic light-splitting microstructures, is provided for separating the incident beam basing on the difference in wavelengths; and the first light emergence surface, being configured with periodic polygon microstructures, is used for receiving the incident beam passing through the first light incident surface while deflecting the optical paths of the resulting split beams for enabling the same to travel in a normal direction of a light emitting surface of the backlight source; and the at least one beam splitting plate, each having periodic microstructures formed thereon, is used for converging the beams from the color separation module while directing the optical paths thereof toward the liquid crystal layer in positions respectively corresponding with multiple sub-pixels thereof, and thereafter, enabling those to be discharged thereout in a direction parallel with the normal direction.
