This paper describes a viewing-zone-angle- expanded color electronic holography system using ultra-high-definition liquid crystal displays (LCDs) with undesirable light elimination. The authors first investigate methods eliminating undesirable light, color aberration, and astigmatism. They then investigate spatio–temporal multiplexing methods to reduce system complexity. These investigations enable an electronic holography system to be constructed using 33 Mpixel LCDs. Experimental results show high-quality full-color 3D images with a diagonal size of 4 cm, viewing-zone-angle of 15 deg, and frame rate of 20 fps.
