Digital Light Processing (DLP) is a show machine based on optical micro-electro-mechanical digital micromirror device. DLP is used for a wide range of show functions from traditional static shows to interactive displays, as well as non-traditional embedded functions including medical, security and industrial applications.
Compared with competing applied sciences, DLP supplies sharp, colourful, clear contrast images. For the reason that area between each micromirror is less than 1 micron, the area between pixels is drastically limited. Therefore, the ultimate image looks clearer. With using a mirror, the light loss is greatly reduced and the light output is kind of high.
Clean (1080p resolution), no jitter image. Excellent geometry and wonderful grayscale linearity are achievable
Using a replaceable light supply means that it might take longer than CRT and plasma displays, and the light from the projected image just isn’t inherently polarized. Light sources are easier to switch than backlights for LCDs and lighter than LCDs and plasma TVs, which are sometimes consumer changeable. The new LED and laser DLP show system more or less eliminates the necessity for lamp replacement. DLP affords affordable 3D projection shows from a single unit and can be utilized with each energetic and passive 3D solutions.
Not like liquid crystal displays and plasma shows, DLP shows don’t depend on the fluid as a projection medium and therefore should not limited by their inherent mirror mechanism, making them ultimate for growing HD cinema and venue screens.
The DLP pico projector can deal with as much as seven completely different colors, giving it a wider color gamut.
DLP, which represents digital light processing, is a Texas Instruments technology. It uses mirrors and color wheels to mirror and filter the projected light. For house and enterprise 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 people solely learn about single-panel DLP projectors.
The one downside of DLP projectors is what believers call “rainbow effects.” Consumer DLP projectors use transparent coloration discs (half-color wheels) rotating in entrance of the lamp. This disk, divided into a number of main colours, reconstructs all the final colors. The place of those main colours is just like the slice of pie. Depending on the projector, there could also be three 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 typically see something like a rainbow, especially in shiny areas of the image. Happily, not everyone sees these rainbows. So before shopping for a DLP projector, make sure to check out some video sequences.
Some viewers discover the tweeter of the color wheel an annoyance. Nonetheless, the driveline might be designed to be silent, and a few 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 color to another, or how the curve appears in the image. In DLP projectors, the way in which to present this gray transition is by turning the light supply on and off sooner in this area. Sometimes, inconsistent dither artifacts can happen in colour conversions.
Because one pixel can not render shadows exactly, error diffusion artifacts caused by averaging shadows on completely different pixels
