Digital Light Processing (DLP) is a display machine based on optical micro-electro-mechanical digital micromirror device. DLP is used for a variety of display functions from traditional static shows to interactive displays, as well as non-traditional embedded functions together with medical, security and industrial applications.

Compared with competing technologies, DLP gives sharp, colourful, clear contrast images. Since the space between each micromirror is less than 1 micron, the area between pixels is enormously limited. Therefore, the final image seems clearer. With the use of a mirror, the light loss is tremendously reduced and the light output is kind of high.

Clean (1080p decision), no jitter image. Perfect geometry and wonderful grayscale linearity are achievable

Using a replaceable light supply signifies that it could take longer than CRT and plasma displays, and the light from the projected image will not be inherently polarized. Light sources are simpler to interchange than backlights for LCDs and lighter than LCDs and plasma TVs, which are sometimes consumer changeable. The new LED and laser DLP display system more or less eliminates the necessity for lamp replacement. DLP offers affordable 3D projection displays from a single unit and can be used with each active and passive 3D solutions.

In contrast to liquid crystal displays and plasma displays, DLP displays do not depend on the fluid as a projection medium and subsequently aren’t limited by their inherent mirror mechanism, making them perfect for growing HD cinema and venue screens.

The DLP projector can handle up to seven completely different colours, giving it a wider shade gamut.

DLP, which represents digital light processing, is a Texas Instruments technology. It uses mirrors and colour wheels to reflect and filter the projected light. For dwelling and business use, the DLP projector uses a reflective panel for all three colors. Digital cinema has three-panel DLP projectors priced at more than 10,000 US dollars. Most people only know about single-panel DLP projectors.


The one downside of DLP projectors is what believers call “rainbow effects.” Consumer DLP projectors use transparent coloration discs (half-shade wheels) rotating in entrance of the lamp. This disk, divided into a number of main colours, reconstructs all the final colors. The place of those major colours is just like the slice of pie. Depending on the projector, there may be three segments (1 red, 1 green and 1 blue) or 4 segments (1 red, 1 green, 1 blue and 1 white), 6 segments (1 red, 1 green, 1 blue, then 1 red, 1 green and 1 blue), and even eight segments have a number of white. The smaller the section, the less the turntable, the stronger the power of the eyes to disassemble the color. This means you typically see something like a rainbow, especially in shiny areas of the image. Fortuitously, not everybody sees these rainbows. So before shopping for a DLP projector, you should definitely check out some video sequences.

Some viewers find the tweeter of the colour wheel an annoyance. Nonetheless, the driveline may be designed to be silent, and some projectors do not produce any audible colour wheel noise.

The perimeters of the projected image between black and light are often jagged. This is called jitter. This is how the image transitions from one shade to a different, or how the curve seems within the image. In DLP projectors, the best projector way to current this gray transition is by turning the light source on and off quicker in this area. Sometimes, inconsistent dither artifacts can happen in colour conversions.

Because one pixel can not render shadows precisely, error diffusion artifacts caused by averaging shadows on completely different pixels
