DLP comes from Digital Light Processing. DLP is developed by Texas Instruments which is also currently the only producer to this technology. The technology is based on microscopically small mirrors, which number depends on the resolution (for example 1024 x 768). The image is based on these mirrors which reflect or not reflect light. The colours are then procuded by routing the light from the lamp through the colour wheel (which has three basic colours blue, red and green) and then the light is followed to the mirrors and out of the projector through the optics.
