Abstract:
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 pivoting microelectrical mechanical actuators that support and selectively pivot plural microelectrical mechanical shutters over the apertures in directions parallel to the planar substrate, 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 through the microelectrical mechanical optical modulator selectively according to the selective pivoting of the shutters; and a display screen that receives the illumination light passing through the microelectrical mechanical optical modulator.
