DLP Projectors (1)

The DLP chip is the central part of this type of projector.

A DLP chip consists of many small pixel-sized mirrors laid out on a semi-
conductor chip. Light shone on the DLP chip is reflected by all these tiny
mirrors. (For a chip with 1024 x 768 resolution, there are 786,432 small
mirrors.)

Light is shone onto the chip through a fast-spinning wheel that has a red
sector, a green sector, and a blue sector. This light is reflected off the chip
and out through a lens onto a screen.
