Abstract:
A trim retarder for a liquid crystal display based projection system including a light source, a polarizer/analyzer, a liquid crystal display panel, and a projection lens, is clocked to an optimal azimuthal angle that provides a system contrast level substantially unaffected by the orientation of the slow axis of the liquid crystal display panel.
