Abstract
A time-sharing holographic color display system is developed using a high-resolution reflective liquid-crystal display (LCD) panel that consists of a 1920x1080 array of square pixels with the pixel pitch of 8.1 micron. Red, green and blue high-resolution images are reconstructed from the holographic display system with a red laser diode (LCD), a green diode-pumped laser and a blue diode-pumped laser. The reconstructed color image can clearly be observed under the room light. The image exhibits a large color gamut good color expression. High-quality color images of the practical object are reconstructed from recorded holograms by using the developed holographic display system. The viewing zone or the visual field of the holographic display is enlarged by adopting a multi-channel LCD modulator. The viewing zone angle or the visual field angle of color images is enlarged up to about 20 degrees by adopting a 6-channel LCD modulator.
