Digital Light Processing (DLP)

A technology developed by Texas Instruments (TI) and used in some projectors and rear projection televisions.

DLP is based on a digital micro-mirror device (DMD); a computer chip with over 480,000 microscopic, hinged mirrors. Red, green and blue light is filtered through a colour wheel that spins at high speed and directed at the micro-mirrors. The reflected light is directed through a lens and onto a screen, creating the image. High end projectors use three DMDs (and no colour wheel), with each of the DMD corresponding to a separate colour (red green or blue).

DLP televisions and projectors produce wonderfully bright images with fantastic contrast and depth of colour.
