DLP technology is based on an optical semiconductor called a DMD chip (Digital Micromirror Device), which was invented in 1987 by Texas Instruments. The way it works is that a DMD chip is made up of millions of tiny mirrors that can rotate at a 12 degrees angle. These mirrors are literally capable of switching on and off thousands of times per second and are used to direct light towards and away from a dedicated pixel space.
LCD uses a number of liquid crystal panels which are illuminated by a single high-wattage metal halide lamp. A series of filters and reflectors split the spectrally pure white light into rays of red, green, and blue. Each of these beams illuminates a liquid crystal panel and the images from the panels converge at the focal point of a single lens.
The key is our LampFree™ hybrid light source technology which completely eliminates the need to purchase and install replacement lamps. Since the cost of lamps is normally as high or higher than the initial cost of the projector, you get superior quality at a low lifetime cost.
The digital signal is now ready to be processed into an image for projection. Currently, there are two technologies used in business and home theater projectors to display images: liquid-crystal display (LCD Projector) and Digital Light Processing (DLP Projector).
