Contrast‐enhanced wide‐angle high‐speed polarization modulator for active‐retarder 3‐D displays

— A contrast-enhanced wide-angle high-speed polarization modulator for active-retarder 3-D displays is proposed. By using a double liquid-crystal-cell structure together with a dedicated driving scheme and an external quarter-wave retarder, a high-performance modulator can be realized, resulting in minimized brightness loss and low cross-talk levels in fast-refresh time-multiplexed 3-D displays.
