What is a DLP Projection System?
The most promising heir to the CRT-based rear-projection television in use today is the DLP (Digital Light Processing) rear-projection television. Like LCD, the actual image is displayed on a chip, however, the chip used in a DLP projection television is different. The chip in a DLP projection television is referred to as a DMD (Digital Micromirror Device). In essence, every pixel on a DMD chip is a reflective mirror.
The video image is displayed on the DMD chip. The micromirrors on the chip then tilt very rapidly as the image changes. This process produces the grayscale foundation for the image. Then, color is added as light passes through a high-speed color wheel and is reflected off of the micromirrors on the DLP chip as they rapidly tilt towards or away from the light source. |
The degree of tilt of each micromirror coupled with the rapidly spinning color wheel determines the color structure of the projected image. As the amplified light bounces off the micromirrors, it is sent through the lens, reflected off a large single mirror, and onto the screen.
