The Science Behind DLP Television

DLP televisions are based on a technology invented by Texas Instruments back in 1987 called Digital Light Processing. The technology is based on an optical semiconductor called DMD (Digital Micromirror Device) chip. It is a highly reliable, all-digital display chip that delivers the best picture across a broad range of products, including large screen digital TVs, and projectors for business, home, professional venue and digital cinema. The chip consists of over one million mirrors to process light. They come in either single chip or 3 chip configurations. One-chip DLP systems use a projection lamp to pass white light through a color wheel that sends red-green-blue colors to the DMD chip in a sequential order to create an image on-screen. Only one DMD chip is used to process the primary RGB colors. Three-chip DLP systems use a projection lamp to send white light through a prism, which creates separate red, green, and blue light beams. Each beam is sent to their respective red, green, and blue DMD chip to process the image for display on-screen. One-chip models are said to produce a display of over 16-million colors. Three-chip models can produce a display of over 35-trillion colors. The result is maximum fidelity: a picture whose clarity, brilliance and color must be seen to be believed. When a DLP chip is coordinated with a digital video or graphic signal, a light source, and a projection lens, its mirrors can reflect an all-digital image onto a screen or other surface. The DLP chip and the sophisticated electronics that surround it are what we call Digital Light Processing technology. Benefits of Single chip DLP: 1. Fantastic color accuracy. 2. The best contrast ratios and shadow detail. 3. Generally very quiet. 4. Very little space between each pixel creates a very smooth image, even when using lower resolution projectors. 5. Light engine failures are very rare so repairs are less costly than other technologies. 6. Technology doesn't degrade over time. With proper routine maintenance, DLP
