![]() ![]() There are two primary methods by which DLP projection systems create a color image: those utilized by single-chip DLP projectors, and those used by three-chip projectors. Rapidly toggling the mirror between these two orientations (essentially on and off) produces grayscales, controlled by the ratio of on-time to off-time. These mirrors can be repositioned rapidly to reflect light either through the lens or on to a heat sink (called a light dump in Barco terminology). The number of mirrors corresponds to the resolution of the projected image (often half as many mirrors as the advertised resolution due to wobulation). Each mirror represents one or more pixels in the projected image. In DLP projectors, the image is created by microscopically small mirrors laid out in a matrix on a semiconductor chip, known as a Digital Micromirror Device (DMD). Availability for final products would show up in the market early 2009. In March 2008, TI announced the initial production of the DPP1500 chipset, which are micro projectors to be used in mobile devices. The single-chip version of DLP and 3LCD are the two main technologies used in modern colour digital projectors, with the two technologies being used in over 95% of the projectors sold in 2008. These rear-projection technologies compete against LCD and plasma flat panel displays in the HDTV market. It is also one of the leading technologies used in digital cinema projection.ĭLP, along with LCD and LCoS, are the current display technologies behind rear-projection television, having supplanted CRT rear projectors.
