Pico-projectors enable a mobile phone to project an image up to 120-inches wide onto almost any flat, whitish surface--for instance presentations or just to share your photos. Look for every mobile phone to have a pico-projector built-in within five years. R.C.J.
Texas Instruments today unveiled its newest digital light processor chip which will enable nHD resolution pico projector modules for the smallest of mobile phones. The DLP chip was announced at the Mobile World Congress (Barcelona, Feb. 15-18, 2010). Texas Instruments pioneered the micro-electro-mechanical system (MEMS) technique of creating millions of movable micromirrors on a chip which reflect the light projected onto them thereby forming images on any projection screen—from the "big screen" at the digital cinema, to home projection televisions and now to hand-held pico projectors. The nHD format (640-by-360 pixels) allows DVDs to be viewed at nearly their full resolution for sharp images even when they are projected at sizes over 50-inches diagonal.
