Digital Light Processing and its Future Applications
      Goldy Katal, Nelofar Tyagi, Ashish Joshi
Abstract: Electronic projection display technology had its origin in the Oil film projector system. Developed in the early 1940s oil film projectors have been the workhorse for applications that require projection displays of the highest brightness. But due to various limitations a number of solid state technologies have challenged the oil firm projector, including CRT-LCD light valves and active-matrix- LCD panels. In response to various limitations of the LCD technologies and to provide superior image quality, high brightness projection display systems have been developed based on Digital Light Processing technology. DLP is based on the Digital Micro Mirror Device (DMD), a Micro Electro Mechanical System, invented in 1987 by Larry Hornbeck at Texas Instruments. DMD is a fast, reflective digital light switch that precisely controls a light source using a binary pulsewidth modulation technique. It can be combined with image processing, memory, a light source, and optics to form a DLP system capable of projecting large, bright, high contrast colour images with better colour fidelity and consistency than current displays. This paper describes the structure, working, operation, advantages and future use of the DLP system. It also compares the DLP system with other display technologies and presents the DLP technology based products in the market.
