DLP® technology is based on the DLP® chip which is comprised of a
standard memory cell on top of which is mounted a rectangular array of
up to a million hinged, microscopic mirrors.
In a DLP® front projection system or HDTV, red, green, and blue light
is shone alternately onto the mirrors, which switch on and off in
response to a video or graphics signal being fed into the underlying
memory chip. The mirrors can switch at a rate of up to 5,000 times per
second; the light they reflect is directed through a lens and onto the
screen, creating an image.
The main display technologies in use today for projection and display applications are:
