Patent ID: 7283112

Claim:
A microelectrical mechanical optical display engine, comprising: a microlens array having an array of plural lenslets for receiving and directing illumination light; an aperture plate through which plural pixel apertures extend, the plural pixel apertures being aligned with and to receive illumination light from the plural lenslets of the microlens array; and a microelectrical mechanical reflector array positioned opposite the aperture plate from the microlens array, the microelectrical mechanical reflector array including plural microelectrical mechanical actuators that support reflectors in alignment with the plural pixel apertures to receive and reflect the illumination light, the plural microelectrical mechanical actuators being constructed and arranged to orient the reflectors selectively to direct the illumination light back through the pixel apertures or against the aperture plate, wherein a microelectrical mechanical actuator is placed in an actuated state having an actuated position by an actuation voltage and held in a storage state to maintain the actuated position by a storage voltage, wherein the storage voltage is less than the actuation voltage.
