Abstract
Vertically aligned nematic mode liquid crystal on silicon micro displays exhibit a residual birefringence in the dark or off-state. This retardance has to be compensated in order to achieve high contrast projection systems. A birefringent film compensator with individually controllable on- and off-axis retardance and high uniformity is presented. Sequential contrast of 4500:1 has been demonstrated in a wire grid polarizer based light engine for a rear projection television.
