Abstract

A light guide fully composed of reflective plate has been proposed for a planar illuminator with the light source located at the side edge. Using mirror reflection as the light guiding mechanism increases the light acceptance angle of the light guide, and the hollow structure allows increasing the source coupling area without inducing further weight. Accompanying with the optical films, for example, a diffuser, a prismatic film, and a reflective polarizer to spread light distribution, the uniformity of the prototype has shown the feasibility for a planar illuminator.
