Abstract :
An ultra small projector with LED light sources is developed to create a new category of projection display. This projector is battery-operated and has the SD port. Therefore this projector requires no power cable and signal cable. To realize the high efficient illumination system, we have developed a novel collimator with four aspheric surfaces. Using this technology, the total lumen of the projected image is improved.
