Abstract

A light uniformizing algorithm based on rectangular CPC is presented for micro-projection display. The designed optical engine with rectangular CPC consists of LED, fly's-eye lens and micro-display panel DMD. The light uniformity on the micro-display panel and energy efficiency of the optical engine with rectangular CPC is analyzed by means of software. Experimental results show that the proposed light uniformizing algorithm and system compared with other uniformizing light algorithm and system have advantages such as lesser capacity, lesser Etendue, higher light uniformity more than 92% and higher energy efficiency of 43% to meet the needs of micro-projection display.
