Digital Light Processing is a product of Texas Instruments which uses a single chip that is made up of up to 2 million microscopic mirrors to project light. This chip is called a Digital Micromirror Device (DMD). Each of the microscopic mirrors that make up the DMD represents a single pixel. These pixels are hinged so that they can tilt back and forth to create different shades of light when pointed at a light source. This first stage of light is in the form of a grayscale, comprised of over 1,000 different shades of white and black. In order to produce a color image, the white light that travels to the DLP™ chip is shown through a color wheel which is coordinated with the tilting back and forth of the microscopic mirrors. This produces a pixilated image of red, green, and blue that when these mirrors move thousands of times per second or eyes naturally blend to make up the real color. This is how the 1-chip DLP™ projection system operates. There is another form of this technology, the 3-chip DLP™ system, which operates with the same basic idea, but contains three chips instead of one. Each of the three chips represents a color, blue, red, and green. The white light that comes into the projector passes through a prism that divides the light into blue, red, and green light. The same process of reflecting the light using the microscopic mirrors then happens. The outcome is similar, but produces a wider range of richer color to form the image.

DLP uses tiny mirrors, one for each pixel, to reflect light. DLP modulates the image by tilting the mirrors either into or away from the lens path. It is therefore a "reflective" technology. It use an all-digital display chip. As opposed to analog systems, the DLP projector uses an optical semiconductor to duplicate source material and manipulate light.

DLP projectors feature the latest technology in audiovisual equipment. Digital Light Processing is the world's only all-digital display chip and a fundamental element in the best digital projectors on the market today. DLP systems employ an optical semiconductor to project a signal with such high fidelity, that analog system simply can't compete.

This system consists of a "Chip" featuring an array of micro mirrors, which are digitally polarized many times per second, thus depending on the number of times that these will be further polarized light reflected by each of these micro mirrors. By using a single "Chip" light that is reflected is passed through a color wheel that rotates so that YOU forming images with different colors.

The advantages of this technology are the mechanism that takes up less space than an LCD, and the grid between pixels is not visible to the naked eye. This gives an image smooth, with good contrasts.

The disadvantages of this technology, which is to have a single element, must share the light to project each color, so dark colors are poor and white is very intense.

Images from DLP projectors tend to be brighter and clearer than from other types, and this technology is the acknowledged growth area in the market. These projectors are among the lightest available, making them ideal for transportation. They are also the most expensive. Here's some distinct features and benefits of DLP projector:

• Offers great ANSI contrast
• Lighter in weight and more compact
• User-replaceable lamp means lower cost of maintenance
• Picture Reliability – Don’t settle for a projector that may experience color decay (yellowing screen image) over time.  DLP® projectors are virtually immune to color decay and give you a picture that lasts.
• Superior Readability – It’s all about contrast ratio and with DLP® projectors, incredibly high contrast levels make it the superior technology for easy to read text and graphics

There are two basic types of DLP projectors: projectors "one chip" used a single DMD chip with a rotating color wheel, while the projectors "3 chips spend a lot more expensive chip for each basic color: red, green, and blue.

The lamp has a higher wattage so they're teams that tend to heat up quickly. Also projectors on a single chip most of them have the rainbow effect (see animation), which many people find it especially annoying to see video.

There DLP Cinema Technology which is based on three "chips" to act as the 3 LCD panels, thereby achieving a Very Good Quality, but they are teams that exceed the 20,000 dls.
