<P>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.</P>
<P>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 project image.</P>
<P>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.</P>
