The advantages and disadvantages of DLP projectors

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

Compared with competing technologies, DLP supplies sharp, colorful, clear distinction images. Because the area between every micromirror is less than 1 micron, the area between pixels is tremendously limited. Subsequently, the final image appears clearer. With using a mirror, the light loss is enormously reduced and the light output is sort of high.

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

Using a substituteable light supply signifies that it might take longer than CRT and plasma displays, and the light from the projected image is just not inherently polarized. Light sources are easier to interchange than backlights for LCDs and lighter than LCDs and plasma TVs, which are sometimes user substituteable. The new LED and laser DLP show 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 both energetic and passive 3D solutions.

Unlike liquid crystal displays and plasma shows, DLP displays don’t depend on the fluid as a projection medium and therefore aren’t limited by their inherent mirror mechanism, making them best for rising HD cinema and venue screens.

The DLP projector can handle as much as seven totally different colors, giving it a wider color gamut.

DLP, which represents digital light processing, is a Texas Instruments technology. It makes use of mirrors and colour wheels to replicate and filter the projected light. For residence and business use, the DLP projector makes use of 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 know about single-panel DLP projectors.


The one downside of DLP projectors is what believers call “rainbow effects.” Shopper DLP projectors use clear colour discs (half-color wheels) rotating in front of the lamp. This disk, divided into several major colours, reconstructs all the ultimate colors. The position of those main colours is just 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 just 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 generally see something like a rainbow, especially in shiny areas of the image. Luckily, not everyone sees these rainbows. So earlier than shopping for a DLP projector, be sure to check out some video sequences.

Some viewers find the tweeter of the colour wheel an annoyance. Nevertheless, the driveline can be designed to be silent, and some projectors don’t produce any audible colour wheel noise.

The perimeters of the projected image between black and light are usually jagged. This is called jitter. This is how the image transitions from one shade to a different, or how the curve appears within the image. In DLP projectors, the best way to present this gray transition is by turning the light supply on and off sooner in this area. Often, inconsistent dither artifacts can occur in colour conversions.

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