What is DLP technology and how does it work?
Digital Light Processing, or DLP technology is an all-digital technology used to project and display images. Invented by Texas Instruments, DLP technology is based on an optical semiconductor called the Digital Micromirror Device, or DMD. Digital Light Processing technology is based on the Digital Micromirror Device, or DMD, an optical switch semiconductor. The DMD is comprised of a standard memory cell on top of which is mounted a rectangular array of more than a million hinged, microscopic mirrors. In a DLP projection system, red, green, and blue light is shone alternately onto the DMD mirrors, which switch on and off in response to a video or graphics signal being fed into the underlying memory chip. The mirrors can switch at a rate of up to 5,000 times per second; the light they reflect is directed through a lens and onto the screen, creating an image. In projectors for high brightness applications, three DMDs are used-one each for green, red, and blue. Light from the lamp is split
