How do DLP Cinema Projectors Work?

DLP Cinema systems have been deployed and tested commercially in theatres since 1999. In June 1999, Star Wars: Episode I – The Phantom Menace was the first movie to be entirely scanned and distributed to theaters. Four theaters installed digital projectors for the...

How do Xenon Arc Projector Lamps Work?

How Do 3 Chip DLP Projectors Work?

A three-chip DLP projector uses a prism to split light from the lamp, and each primary color of light is then routed to its own DLP chip, then recombined and routed out through the lens. Three chip systems are found in higher-end home theater projectors, large venue...
