DLP Projector

DLP Projector is an optical system driven by digital electronics. Its the only display solution that enables movie video projectors, televisions, home theater systems and business video projectors to create an entirely digital connection between a graphic or video source and the screen in front of you. At the heart of every DLP projection system is an optical semiconductor that manipulates light digitally known as the Digital Micromirror Device, or DLP chip which is a rectangular array of up to 2 million hinge-mounted microscopic mirrors( each of these micro mirrors measures less than one-fifth the width of a human hair. When a DLP chip is coordinated with a digital video or graphic signal, a light source, and a projection lens, its mirrors can reflect an all-digital image onto a screen or other surface. It has three key advantages over existing projection technologies. The digital nature of DLP enables digital gray scale and color reproduction and also positions DLP to be the final link in the digital video infrastructure. Because it is based on the reflective DMD, DLP is more efficient than competing transmissive LCD technologies. Finally, DLP has the ability to create seamless, film like images. DLP makes images look better. You\'ve heard the digital revolution, now see it with Digital Light Processing.
