The advantages and disadvantages of DLP projectors

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

Compared with competing technologies, DLP provides sharp, colourful, clear contrast images. For the reason that house between every micromirror is less than 1 micron, the area between pixels is vastly limited. Due to this fact, the final image appears clearer. With the usage of a mirror, the light loss is tremendously reduced and the light output is sort of high.

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

Utilizing a replaceable light supply signifies that it may take longer than CRT and plasma displays, and the light from the projected image is not inherently polarized. Light sources are simpler to interchange than backlights for LCDs and lighter than LCDs and plasma TVs, which are sometimes person replaceable. The new LED and laser DLP show system more or less eliminates the need for lamp replacement. DLP gives affordable 3D projection displays from a single unit and can be used with each energetic and passive 3D solutions.

Not like liquid crystal displays and plasma displays, DLP shows do not rely on the fluid as a projection medium and therefore should not restricted by their inherent mirror mechanism, making them excellent for rising HD cinema and venue screens.

The DLP projector can deal with as much as seven different colours, giving it a wider color gamut.

DLP, which represents digital light processing, is a Texas Instruments technology. It makes use of mirrors and shade wheels to mirror 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 10,000 US dollars. Most individuals solely know about single-panel DLP projectors.


The only downside of DLP projectors is what believers call “rainbow effects.” Shopper DLP projectors use transparent colour discs (half-colour wheels) rotating in entrance of the lamp. This disk, divided into several major colors, reconstructs all the final colors. The position of those major colours 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 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 typically see something like a rainbow, particularly in bright areas of the image. Happily, not everybody sees these rainbows. So earlier than buying a DLP projector, make sure to check out some video sequences.

Some viewers discover the tweeter of the color wheel an annoyance. However, the driveline may be designed to be silent, and some projectors don’t produce any audible color wheel noise.

The perimeters of the projected image between black and light are often jagged. This is called jitter. This is how the image transitions from one coloration to another, or how the curve appears within the image. In DLP projectors, the best projector way to current this gray transition is by turning the light source on and off sooner in this area. Often, inconsistent dither artifacts can occur in color conversions.

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