Abstract

A display method, two-field driving scheme based on angularly positioned color LEDs, is proposed for field sequential color liquid crystal displays (LCDs) without color filters. In each field, the angular rays of two colors from LEDs are collimated by a collimation lens, redirected by a light guide and converged by a cylindrical-lens array to map into corresponding sub-pixel positions for efficiently displaying color image.
