High Definition Display Based on the Digital Micromirror Device (DMD) SpatialLight Modulator

摘要

This report describes the effort over a six year period to develop a highdefinition display using the Texas Instrument (TI) Digital Micromirror Device (DMD) formerly deformable mirror device. The majority of this work carried out at TI in Dallas, Texas and its subcontractor, the David Sarnoff Research Center (Sarnoff) in Princeton, New Jersey. The program began in March 1990 and ended in March 1996 with the delivery of an HD projection display to the Government. This program resulted in the world's largest micro-electro-mechanical system (MEMS) device, from the standpoint of the number of moving mechanical structures (2,359,296 mirrors), built on a single monolithic chip. Three of these chips were used to bulld a truly digital high definition front projection display.
