The possibility of an all-digital (sourceto-eye) projection display was realized in 1987 with the invention of the Digital Micromirror Device™ projection display chip at Texas Instruments (TI). The DMD™ chip is a microelectromechanical systems (MEMS) array of fast digital micromirrors, monolithically integrated onto and controlled by an underlying silicon memory chip. Digital Light Processing™ projection displays are based on the DMD chip. DLP™ projection displays present bright, seamless images to the eye that have high image fidelity, and stability.
Larry J. Hornbeck is a TI Fellow in DLP™ Products at Texas Instruments in Dallas. In 1987, he invented the Digital Micromirror Device™ projection display chip, a MEMS array of fast digital light switches monolithically integrated onto a silicon address circuit. He has continued to develop architectures and fabrication processes to improve performance and reliability. The DMD™ display chip forms the basis for Texas Instruments Digital Light Processing™ projection display technology.
Hornbeck has received numerous awards for his invention of the DMD display chip, including Germany's Eduard Rhein Foundation Technology Award, England's Rank Prize, an Emmy™ Award from the Academy of Television Arts & Sciences, and the Karl Ferdinand Braun Prize from the Society for Information Display. He holds 30 patents in CCD, infraredimage- sensor, and DMD technology, including the fundamental patent for the DMD display chip. He received his PhD degree in solidstate physics from Case Western Reserve University in 1974.
