Abstract (en)

[origin: WO2015103633A1] A system (100), method (900), and apparatus (110) for displaying an image (880). The system (100) can utilize two or more diffusers (282) separated by a gap (290) to reduce the coherence of the light (800) used in the display of the image (880). The diffusers (282) can be diffuser film (283), diffuser paper (284), diffuser glass (285), diffuser coatings (286), or virtually any form of multi-textured surfaces (287). The gap (290) between two diffusers (282) can be an air gap (291 ), a glass gap (292), or some other form of space that is different from the diffusers (282) and at least semi-transparent. The system (100) can be embodied as a DLP system (141 ), an LCD system (142), an LCOS system (143), a system (100) utilizing virtually any type of display technology (140).
