Abstract

Advances in front projection technology, particularly imager chips and illumination sources, are heralding a whole "New Era" of sub-500 lumen projectors that are significantly smaller and/or cheaper than the classical (500+ lumen) models available up to now. Liquid crystal and MEMS technology imager chips are being joined by MOEMS scanner chips, and lamps are being joined by LEDs and lasers. These New Era models are finding myriad applications, from wall-powered toy and gaming projectors (for which price, not size, is the key consideration) and personal projectors that can be used for a variety of vertical markets, to a host of viewing needs that can be filled by tiny battery-powered pico projectors.
