DLP™ Overview
DLP™ technology is a revolutionary display solution that uses an optical semiconductor to manipulate light digitally, creating an authentic feel in your home theater setup.
 At the heart of DLP™ projectors is an optical semiconductor known as the Digital Micromirror Device, or DMD chip. The DMD and the sophisticated electronics that surround it are called Digital Light Processing™ technology.
The DLP™ system contains a rectangular array of up to 2 million hinge-mounted microscopic mirrors that measure less than one-fifth the width of a human hair. Mounted on tiny hinges that enable them to tilt either toward the light source in a DLP™ projection system (ON) or away from it (OFF), these mirrors reflect an all-digital image onto a screen or other surface. In fact, the mirrors in DLP™ home projectors can reflect pixels in up to 1,024 shades of gray to convert the video or graphic signal into a highly detailed grayscale image.

The white light generated by the lamp in DLP™ projectors pass through a color wheel as it travels to the surface of the DMD panel. The color wheel filters the light into red, green, and blue, from which single-chip DLP™ projectors create at least 16.7 million colors, filling the room of your home theater setup.
White light passes through a color wheel filter, causing red, green and blue light to be shone in sequence on the surface of the DMD. The switching of the mirrors and the proportion of time they are 'on' or 'off', is coordinated according to the color shining on them. The human eye integrates the sequential color and sees a full-color image.
Televisions, business and home projectors using DLP™ technology rely on a single DMD chip configuration like the one described above.

Benefits of DLP™
DLP™ technology is in use wherever visual excellence is in demand - especially your home theater setup. In fact, it's the only display solution that enables home projectors, televisions, business projectors, and other home theater systems to create an entirely digital connection between a graphic or video source and the screen in front of you.

You'll experience a smarter product in your home theater setup, as DLP™ technology is helping to create the most cutting edge projection technology. The Digital Micromirror Device, the heart of DLP™ technology, can modulate light much more quickly than other display ingredients. That means DLP™ projectors only have one panel (other technologies usually require three) so your system is smaller and lighter. The reliability stems from DLP™ technology as well, making your home theater system more robust, repelling heat, humidity and vibration. Finally, its versatility allows you to bring the same peerless visual standard to entertainment, work, and play. As far as we're concerned, you can't have innovation without versatility, so projectors had to fit wherever you do.
When home projectors are turned on, beautiful pictures are displayed as DLP™ technology provides the absolute maximum fidelity. Those images are always sharp and crystal clear with DLP™ technology because it comes closer than any other display solution to reproducing the exact mirror image of its source material. Picture's enduring brightness is created by the DLP™ projection system that outshines the alternatives because, being mirror-based, they use light more efficiently. More light from the lamp, means more light on the screen in your home theater setup. We could talk about it all day, but the color has to be seen to be believed.
