DLP
Stands for Digital Light Processing. It is a microdisplay technology invented by Texas Instruments, DLP is based on a digital micromirror device (DMD), a chip with millions of hinged, microscopic mirrors attached. Each mirror corresponds to a single pixel in the projected image. Red, green, and blue light filtered through a colour wheel is directed alternately onto the DMD, which switches on and off up to 5,000 times a second. The reflected light is directed through a lens and onto a screen, creating an image. High-end HDTV projectors use a three-chip solution, with separate DMD's for green, red, and blue, and forego the colour wheel.
