ABSTRACT Electronic projection display technology for high-brightness applicationshad its origins in the Gretag Eidophor, an oil film-based projection systemdeveloped in the early 1940s. A number of solid state technologies have challengedthe Eidophor, including CRT-addressed LCD light valves and active-matrix-addressed LCD panels. More recently, in response to various limitations of theLCD technologies,high-brightness systems have been developed based on Digitallight Processing tm technology. At the heart of the DLP tm projection display is theDigital Micromirror Device tm (DMD)tm, a semiconductor-based array of fast,reflective digital light switches that precisely control a light source using a binarypulse width modulation technique. This paper describes the design, operation, performance, and advantages ofDLP-based projection systems for high-brightness,high-resolution applications. Italso presents the current status of high-brightness products that will soon be on themarket.
