DLP 
Digital Light Processing 
A data projection technology used for projecting images from a computer onto a much larger screen. DLP projectors use a color wheel and an array of tiny mirrors, each corresponding to a single pixel, that tilt back and forth to control the amount of light hitting the lens. The technology delivers a higher contrast ratio with truer blacks, and it doesn't suffer from the pixelation (known as the "screen-door" effect) that plagues LCD projectors.
