DLP (Digital Light Processing) technology utilizes a small Digital Micromirror Device (DMD) to tilt more than 1.3 million micromirrors-each of them less than the width of a human hair-toward (ON) or away from (OFF) the light source inside the DLP. This process creates light or dark pixels on the face of the projection screen. The light then filters to a color wheel, which rotates 120 times per second, producing the correct hue. Each mirror can turn on or off several thousands of times per second resulting in a technology that can reproduce up to 1024 shades of gray. In short, the gradations in color that make DLP images stand-out are the result of color filters backlit by just the right intensity of white light. There are 4 main components in the system: the DMD chip, color wheel, light source, and optics. Light from the lamp passes through a color wheel filter and into the DMD chip which will switch its mirrors on or off in relation to the color reflecting off them, producing an image.
