What makes DLP television technology so unique is that it uses a small digital micromirror device, or DMD, to tilt over 1.3 million tiny mirrors, each smaller than the width of a human hair. Each of these tiny mirrors is tilted either toward or away from the source of the light, thus producing the light and dark pixels that make up the display. DLP televisions are rear projection TVs, but they are not as large, as heavy or as bulky as the traditional rear projection televisions of years past.
