  • Spatial light modulator
    Patent number: 7629197
    Abstract: An interferometric spatial light modulator comprises of two cavities. One is the optical resonant cavity having a partially reflective film and a movable reflective membrane as two walls, and the other is the electromechanical actuation cavity having the movable reflective membrane and a bottom metal layer as electrodes. The spatial light modulator is built on silicon substrate and is actively addressed. A microdisplay apparatus of such spatial light modulators and a projection display system using such microdisplay are also disclosed.
