Abstract
Abstract—A highly compact single‐beam cholesteric liquid‐crystal video projection optics is presented. Cholesteric filters in series with liquid‐crystal light modulators are switched pixel by pixel in a subtracting color‐modulation scheme. No absorbing polarizers or dye filters are used. The projector exhibits an excellent efficiency of 20% for white light, high contrast, and full‐color saturation.Keywords
