ABSTRACT:
A system and method for increasing contrast in displays using micromechanical light modulators. Contrast is enhanced by an optical system that uses polarization to discriminate unmodulated light. Contrast obtained from polarization sensitive components of an optical system has a multiplicative effect on contrast already available.
