The inventor of the DLP digital imaging chip from Texas Instruments will discuss the origins and workings of the technology in a special lecture marking National Engineers Week.

Dr. Larry Hornbeck will speak Wednesday, Feb. 17, at 5 p.m. in TI Auditorium (ECSS 2.102) in the Erik Jonsson School of Engineering and Computer Science at UT Dallas.

Titled “DLP Technology: Extreme Versatility,” the talk will be followed by an open discussion about how a concept can survive development and then blossom into unexpected applications.

The heart of the DLP chip is the Digital Micromirror Device (DMD), an optical semiconductor that includes as many as 2 million hinged, tiltable, individually controllable micromirrors. The DMD’s tiny mirrors tilt thousands of times a second to create an image by directing pulses of light through a projection lens and onto a television, presentation or movie theater screen.

DLP technology is used in a variety of display products ranging from pico-projectors embedded in cell phones to a wide selection of DLP front-projectors and rear-projection HDTVs to TI’s DLP Cinema projectors that light up nearly 11,000 screens globally. Hornbeck holds a series of seminal patents that form the foundation for DMD technology, and he has received numerous awards and honors, including an Emmy Engineering Award from the Academy of Television Arts & Sciences.

In May 2009 he was inducted into the National Inventors Hall of Fame. He is a TI fellow, an IEEE fellow, a fellow of the International Society for Optical Engineering and an elected member of the National Academy of Engineering.
