Patent ID: 6967761

Claim:
A microelectrical mechanical optical display system, comprising: an illumination source that provides illumination light; a collimating lens that receives the illumination light and forms from it collimated illumination light; a converging microlens array having an array of plural lenslets that converge the collimated illumination light; a microelectrical mechanical optical modulator including a planar substrate through which plural pixel apertures extend and plural microelectrical mechanical out-of-plane thermal buckle-beam actuators that support and selectively position plural microelectrical mechanical shutters over the apertures, the microelectrical mechanical optical modulator being positioned such that the pixel apertures receive the illumination light from the converging microlens array, the illumination light passing the microelectrical mechanical optical modulator selectively according to the selective positioning of the shutters; a display screen that receives the illumination light passing the microelectrical mechanical optical modulator; and a projection microlens array positioned between the microelectrical mechanical optical modulator and the display screen and having an array of plural lenslets that project the illumination light to the display screen.
