COLLIMATED SYSTEM WITH MULTI-BACKLIGHT SOURCE |
摘要 |
A multi-backlight collimated system at least comprises a plurality of light sources, a plurality of reflection elements, and at least a collimation element. The light sources are for providing light. Each reflection element has a reflective surface corresponding to one of the light sources and is disposed to reflect light from the corresponding light source. The reflective surface reflects light being emitted in a predetermined direction by the corresponding light source to form a projection area on a screen. The adjacent projection areas on the screen are joined at adjacent side edges. The collimation element is disposed on the screen for altering a path of light penetrating the screen and emitting light in a specific direction The multi-backlight collimated system is easily fabricated into large sizes and is beneficial for products having large display areas.
