ABSTRACT:
A multi-state light modulator comprises a first reflector104. A first electrode142is positioned at a distance from the first reflector104. A second reflector14is positioned between the first reflector104and the first electrode142. The second reflector14is movable between an undriven position, a first driven position, and a second driven position, each having a corresponding distance from the first reflector104. In one embodiment, the light modulator has latch electrodes17and143, which hold the light modulator in a driven state. In another embodiment the latch electrodes17and143are used to alter the actuation and release thresholds of the light modulator.
