Abstract

In this paper, we focus on improving the performance of the SLM based on Liquid Crystal on Silicon, like frame rate, color control, phase linearity, surface flatness and surface process. The colorfulness is realized by lighting different laser light source with color sequential driving method. With this method, the color could be recovered simply using compact three color light sources, like in the present AR glasses. The lights are collimated and illuminate the SLM panel in pre-set time sequence, synchronized with the display content. Light efficiency has always been a great concern. It is important to increase the light efficiency while not decrease the diffraction efficiency at the same time.
