Paper Abstract

We propose and demonstrate a single DLP projection system with high illumination efficiency by the moving color stripe method. White light from the lamp is split and focused as color images by the color filter and lens cells of spiral lens wheel (SLW). Fly eye lens and relay lens superpose color bars on the light valve, and then 3 color strips are scrolled linearly by rotating SLW. As a result, the system output is evaluated as 1.7 times compared to a typical single panel DLP system.
