DLP TV
DLP TV technology could emerge as the best choice for affordable large screen displays.
DLP TV is a rear-projector technology similar to the LCD rear projection TV. At the heart of the DLP TV is the Digital Micromirror Device (DMD). The DMD uses tiny mirrors to reflect colored light onto the screen. The DMD is a technical marvel developed by Texas Instruments in 1996. Effectively over 750,000 mirrors 13.8 microns square spaced just 0.8 microns apart, each mirror represents a single pixel in the display. DLP TV technology is so successful that some movie theaters are equipped with DLP projectors.
- DLP TV is a low-energy, low-heat display.
- DLP TV has no screen door effect found in LCD projection displays.
- Fixed pixel display means sharp, high-contrast images.
- A rear projection DLP TV is smaller and lighter than CRT.
- DLP technology is used in digital movie theaters.
- DLP TV only has a finite number of pixels.
- To deliver the picture of a CRT running 1080i a resolution of 1920x1080 would be required.
- Rainbow effect can occur on DLP TVs when a viewer quickly looks from one side of the display to other.
- Motion artifacts that appear as noise around high-contrast images moving across the screen may be a problem for single-chip DLP TV.
