采用高分辨率反射液晶显示器（LCD）面板，设计了一种分时全息彩色显示系统，该液晶显示器由1920x1080方形像素阵列组成，像素间距为8.1微米。利用红色激光二极管（LCD）、绿色二极管泵浦激光器和蓝色二极管泵浦激光器重建全息显示系统中的红、绿、蓝三色高分辨率图像。在室内光线下可以清晰地观察到重建的彩色图像。该图像呈现出较大的色域，色彩表现良好。利用所研制的全息显示系统，再现了实际物体的高质量彩色图像。采用多通道液晶调制器扩大了全息显示器的视域或视野。采用6通道LCD调制器，将彩色图像的视区角度或视场角度放大约20度。
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.
