What is the difference between LCD and DLP projectors?

DLP (Digital Light Processors) and LCD (Liquid Crystal Display) are two competing technologies used in multimedia projectors. Most multimedia projectors use LCD technology. However, in the last few years many manufacturers have switched to applying DLP technology. Generally, there is no a noticeable difference between these two technologies.

LCD (liquid crystal display) projectors usually contain three separate LCD glass panels, one for each color. The three colors (red, green, and blue) form the image signal being fed into the projectors lens. As light passes through the LCD panels, individual pixels can be opened to allow light to pass through the lens or closed to block the light. This activity modulates the light and produces the image that is projected onto the screen. DLP (Digital Light Processing) is a proprietary technology developed by Texas Instruments. It works differently than an LCD projector. Instead of having glass panels through which light passes, the DLP chip is a reflective surface consisting of thousands of tiny mirrors. Each of these mirrors represents a single pixel. In a DLP projector, light from the projectors lamp is directed onto the surface of the DLP chip. The mirrors move back and forth, directing light either into the lens to turn the pixel on or away from the lens to turn it off. In expensive
