Title :
Thin-film actuated mirror spatial light valve for high-brightness projection displays
Abstract :
Summary form only given. At the present time, there is no projection display device that can transmit enough light to the screen for the display of electronic images at normal room light condition with high brightness and high contrast. Thin Film Actuated Mirror Array (TFAMA) is a breakthrough reflective type light modulator that uses micromachined thin-film piezoelectric actuators in conjunction with microscopic mirrors. In this paper, the operation, design, fabrication, and performance of TFAMA devices are described for high-brightness projection display systems.
