At the heart of every TI DLP® projection system is an optical semiconductor known as the DLP chip, which was invented by Dr. Larry Hornbeck of Texas Instruments in 1987.
The DLP chip is perhaps the world's most sophisticated light switch. It contains a rectangular array of up to 8.8 million hinge-mounted microscopic mirrors; each of these micromirrors measures less than one-fifth the width of a human hair. The DLP chip micromirrors tilt either toward the light source in a DLP projection system (ON) or away from it (OFF). This creates a light or dark pixel on the projection surface.
When a DLP chip is coordinated with a digital video or graphic signal, a light source, and a projection lens, its mirrors can reflect a digital image with precise color onto any surface from 60 inches up to over 100 feet wide.
Although known worldwide for its projection technology, Texas Instruments DLP technology enables innovative optical solutions that disrupt existing end equipment and create new markets. The DLP chip can be used for high speed, efficient, and reliable spatial light modulation. The flexible and programmable DLP technology is redefining industrial, medical, telecom, security, and many other applications. With TI's powerful yet easy-to-use development tools, customers are able to reduce design cycles and deliver disruptive products.
