Some of the indispensable parts of a projector are the feed spool, xenon
arc lamp, projection lens, optical sound head, take up spool, an aperture,
normal lens and a rotating shutter. But with the advancement of science,
new technologies have come into play. The projectors have become much more
advanced in terms of clarity of picture and the quality of the pixels.
Also, the projectors have found use in everyday households, as new versions
of domestic projectors have arrived on the market. The abundance of LCD
projectors, DLP projectors and video projectors has allowed the common man
to enjoy the experience of a big theater hall in his living room.
DLP, or Digital Light Processing, is a technology implemented in today’s
projectors and projection televisions. In DLP projectors, the image is
created by microscopically small mirrors. These minute pieces are then put
in a matrix on a semiconductor chip. This chip is called DMD (Digital
Micromirror Device). These mirrors are treated as pixels. The number of
those minutely small mirrors exactly corresponds with the resolution of the
There are single-chip projectors and three-chip projectors. A single-chip
projector has a single DMD, and a single color wheel produces all the
colors. The color wheel is divided into four sectors of basic primary
colors. They are red, green, and blue, and an additional clear section to
boost brightness. A three-chip DLP projector uses a prism to split light
from the lamp. Then the basic colors are routed to their own DMD chip. Then
these colors are passed through the lens, where they are combined together.
