The advantages and disadvantages of DLP projectors

Digital Light Processing (DLP) is a show system primarily based on optical micro-electro-mechanical digital micromirror device. DLP is used for a wide range of display purposes from traditional static displays to interactive displays, as well as non-traditional embedded purposes including medical, safety and industrial applications.

Compared with competing applied sciences, DLP provides sharp, colourful, clear distinction images. Because the space between every micromirror is less than 1 micron, the area between pixels is tremendously limited. Due to this fact, the ultimate image appears clearer. With the usage of a mirror, the light loss is enormously reduced and the light output is quite high.

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

Using a replaceable light source signifies that it could take longer than CRT and plasma shows, and the light from the projected image isn’t inherently polarized. Light sources are easier to switch than backlights for LCDs and lighter than LCDs and plasma TVs, which are sometimes person exchangeable. The new LED and laser DLP display system more or less eliminates the necessity for lamp replacement. DLP presents affordable 3D projection displays from a single unit and can be used with each energetic and passive 3D solutions.

In contrast to liquid crystal shows and plasma displays, DLP shows don’t rely on the fluid as a projection medium and subsequently are usually not restricted by their inherent mirror mechanism, making them best for rising HD cinema and venue screens.

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

DLP, which represents digital light processing, is a Texas Instruments technology. It uses mirrors and color wheels to replicate 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 top 10 mini projector,000 US dollars. Most people only learn about single-panel DLP projectors.


The one downside of DLP projectors is what believers call “rainbow effects.” Shopper DLP projectors use transparent coloration discs (half-shade wheels) rotating in entrance of the lamp. This disk, divided into a number of major colours, reconstructs all the ultimate colors. The place of those main colors 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 8 segments have a few white. The smaller the section, the less the turntable, the stronger the flexibility of the eyes to disassemble the color. This means you generally see something like a rainbow, especially in brilliant areas of the image. Happily, not everyone sees these rainbows. So before buying a DLP projector, make sure you 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 colour to another, or how the curve seems within the image. In DLP projectors, the way in which to current this grey transition is by turning the light supply on and off sooner in this area. Occasionally, inconsistent dither artifacts can happen in color conversions.

Because one pixel cannot render shadows precisely, error diffusion artifacts caused by averaging shadows on totally different pixels
