The advantages and disadvantages of DLP projectors

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

Compared with competing technologies, DLP offers sharp, colorful, clear distinction images. Because the area between each micromirror is less than 1 micron, the area between pixels is significantly limited. Subsequently, the final image appears to be like clearer. With the use of a mirror, the light loss is enormously reduced and the light output is quite high.

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

Using a exchangeable light supply signifies that it may take longer than CRT and plasma displays, and the light from the projected image is just not inherently polarized. Light sources are easier to replace than backlights for LCDs and lighter than LCDs and plasma TVs, which are often user exchangeable. The new LED and laser DLP display system more or less eliminates the necessity for lamp replacement. DLP offers affordable 3D projection shows 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 displays don’t rely on the fluid as a projection medium and due to this fact should not limited by their inherent mirror mechanism, making them ideally suited for rising HD cinema and venue screens.

The DLP projector can handle as much as seven 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 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 people only learn about single-panel DLP projectors.


The only downside of DLP projectors is what believers call “rainbow effects.” Client DLP projectors use transparent shade discs (half-coloration wheels) rotating in entrance of the lamp. This disk, divided into several main colors, reconstructs all the final colors. The position of those primary colors is just like the slice of pie. Relying on the projector, there may 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 8 segments have a few 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 brilliant areas of the image. Thankfully, not everyone sees these rainbows. So earlier than shopping for a DLP projector, remember to check out some video sequences.

Some viewers discover the tweeter of the color wheel an annoyance. Nevertheless, the driveline might be designed to be silent, and some projectors don’t 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 color to another, or how the curve appears in the image. In DLP projectors, the way to current this gray transition is by turning the light source on and off faster in this area. Often, inconsistent dither artifacts can occur in color conversions.

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