The advantages and disadvantages of DLP projectors

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

Compared with competing applied sciences, DLP offers sharp, colorful, clear distinction images. For the reason that space between every micromirror is less than 1 micron, the space between pixels is greatly limited. Therefore, the ultimate image seems clearer. With using a mirror, the light loss is vastly reduced and the light output is sort of high.

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

Using a exchangeable light supply implies that it could take longer than CRT and plasma displays, and the light from the projected image just isn’t inherently polarized. Light sources are simpler to exchange than backlights for LCDs and lighter than LCDs and plasma TVs, which are often consumer replaceable. The new LED and laser DLP display system more or less eliminates the need for lamp replacement. DLP presents affordable 3D projection shows from a single unit and can be used with both energetic and passive 3D solutions.

Not like liquid crystal displays and plasma shows, DLP displays do not depend on the fluid as a projection medium and due to this fact aren’t limited 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 color gamut.

DLP, which represents digital light processing, is a Texas Instruments technology. It uses mirrors and coloration wheels to mirror and filter the projected light. For dwelling and enterprise 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 individuals solely find out about single-panel DLP projectors.


The one downside of DLP projectors is what believers call “rainbow effects.” Client DLP projectors use clear colour discs (half-color wheels) rotating in front of the lamp. This disk, divided into a number of major colours, reconstructs all the final colors. The position of these main colors is like the slice of pie. Relying on the projector, there could also be 3 segments (1 red, 1 green and 1 blue) or four 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 couple of white. The smaller the section, the less the turntable, the stronger the ability of the eyes to disassemble the color. This means you generally see something like a rainbow, especially in shiny areas of the image. Fortuitously, not everyone sees these rainbows. So earlier than buying a DLP projector, be sure to check out some video sequences.

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

The perimeters of the projected image between black and light are normally 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 way to current this gray transition is by turning the light source on and off quicker in this area. Sometimes, inconsistent dither artifacts can occur in color conversions.

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