Title: Optimizing LEDs for Driving Pico-Projectors

Abstract: Pico projectors are emerging as a tool for sharing information as well as enabling completely new applications made possible by their small size. LEDs are emerging as the light source of choice for these tiny projection systems. We will examine the requirements of small projectors using color-sequential imagers. The optimization of RGB LEDs to meet these requirements in brightness, efficacy (lm/W), size and cost for a variety of pico-projector engine designs is examined in conjunction with other key components used in the projector such as the imager type and size, optics used and the drive electronics.
