The advantages and disadvantages of DLP projectors

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

Compared with competing technologies, DLP supplies sharp, colourful, clear contrast images. For the reason that area between each micromirror is less than 1 micron, the space between pixels is vastly limited. Subsequently, the final image appears to be like clearer. With the usage of a mirror, the light loss is greatly reduced and the light output is sort of high.

Easy (1080p resolution), no jitter image. Excellent geometry and excellent grayscale linearity are achievable

Utilizing a exchangeable light supply means that it may take longer than CRT and plasma displays, and the light from the projected image is not inherently polarized. Light sources are easier to interchange than backlights for LCDs and lighter than LCDs and plasma TVs, which are sometimes user changeable. The new LED and laser DLP show system more or less eliminates the necessity for lamp replacement. DLP provides affordable 3D projection shows from a single unit and can be used with each active and passive 3D solutions.

Unlike liquid crystal displays and plasma shows, DLP shows do not rely on the fluid as a projection medium and subsequently aren’t restricted by their inherent mirror mechanism, making them ideal for rising HD cinema and venue screens.

The DLP projector can handle up to seven totally different colors, giving it a wider coloration gamut.

DLP, which represents digital light processing, is a Texas Instruments technology. It makes use of mirrors and colour wheels to mirror and filter the projected light. For home and enterprise 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 individuals only know about single-panel DLP projectors.


The only downside of DLP projectors is what believers call “rainbow effects.” Shopper DLP projectors use transparent coloration discs (half-colour wheels) rotating in front of the lamp. This disk, divided into a number of main colors, reconstructs all the final colors. The position of those main colours is like the slice of pie. Relying on the projector, there could also be 3 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 few white. The smaller the part, the less the turntable, the stronger the flexibility of the eyes to disassemble the color. This means you sometimes see something like a rainbow, particularly in brilliant areas of the image. Happily, not everyone sees these rainbows. So before shopping for a DLP best projector, remember to check out some video sequences.

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

The sides 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 another, or how the curve seems in the image. In DLP projectors, the way in which to present this gray transition is by turning the light source on and off sooner in this area. Sometimes, inconsistent dither artifacts can happen in shade conversions.

Because one pixel can’t render shadows exactly, error diffusion artifacts caused by averaging shadows on different pixels
