Digital Light Processing

Abstract : Seminar ppt Digital Light Processing (DLP) is a registered trademark of Texas Instruments, which is a technology used in some television and video projectors. It was originally developed in 1987 by Dr. Larry Hornbeck of Texas Instruments. DLP is used in DLP front projectors (small standalone projection units) and DLP rear projection TV. DLP, LCD and LCoS are the current display technologies behind rear-projection television, which has supplanted CRT projectors back. These rear-projection technologies compete against LCD and plasma flat screen in the market for HDTV. Single-chip version of the DLP and 3LCD are the two main technologies used in modern digital projector color, with the two technologies used in more than 95% of projectors sold in 2008. DLP is also one of the technologies used in digital cinema projection. There are two main methods by which DLP projection systems create a color image: those used for single-chip DLP projectors, and those used by the three-chip projectors. A third method, the sequential illumination by three colored LEDs are being developed, and is currently used in televisions manufactured by Samsung. Yet another method, color laser printers, is being used by Mitsubishi LaserVue products
