DLP Television Technology DLP Semiconductor Technology At the
heart of every DLP television is an optical semiconductor known
as the Digital Micromirror Device, or DMD chip. The DMD chip is
probably the world's most sophisticated light switch. It
contains a rectangular array of up to 1.3 million hinge-mounted
microscopic mirrors; each of these micromirrors measures less
than one-fifth the width of a human hair, and corresponds to one
pixel in a projected image. When a DMD 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. The DMD and the sophisticated
electronics that surround it are what we call Digital Light
Processing technology. DLP Television Grayscaling A DMD panel's
micromirrors are mounted on tiny hinges that enable them to tilt
either toward the light source in a DLP television (ON) or away
from it (OFF)-creating a light or dark pixel on the projection
surface. The bitstream im
