DLP

TV DLP

Digital Light Processing(Digital Light Processing) is a technology used in projectors and projection televisions. In DLP projectors, the image is created by microscopic mirrors arranged in a matrix on a semiconductor chip, known as Digital Micromirror Device (DMD). Each mirror represents a pixel in the projected image. The number of mirrors corresponds to the resolution of the projected image: the parents of 800? 600, 1024? 768, and 1280? 720 are some of the common sizes DMD. .-In a projector with a single DMD chip, colors are produced by placing a color wheel between the lamp and the DMD where it is reflected through the optical. The color wheel is usually divided into three sectors, the primary colors: red, green and blue, and an additional clear section to shine. Since the clear sector reduces color saturation in some models can be effectively disabled, and others are omitted altogether.

The DMD chip is synchronized with the movement of rotation of the color wheel to display the green component in the DMD when the green section of the color wheel is in front of the lamp. The same goes for red and blue sections. The images of red, green and blue are displayed sequentially at a frequency so high enough for the viewer to see the composite image in "full color".

DLP lamps have a short shelf life and must be replaced in 1000 than 6000 hours.
