Digital Light Processing (DLP) is a display system based on optical micro-electro-mechanical digital micromirror device. DLP is used for a wide range of display applications from traditional static shows to interactive displays, as well as non-traditional embedded applications including medical, security and industrial applications.
Compared with competing technologies, DLP supplies sharp, colorful, clear distinction images. Since the space between every micromirror is less than 1 micron, the space between pixels is significantly limited. Due to this fact, the final image seems clearer. With using a mirror, the light loss is drastically 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 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 simpler to replace 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 presents affordable 3D projection shows from a single unit and can be utilized with each lively and passive 3D solutions.
Not like liquid crystal shows and plasma shows, DLP displays do not depend on the fluid as a projection medium and subsequently will not be restricted by their inherent mirror mechanism, making them ultimate for growing HD cinema and venue screens.
The DLP projector can handle as much as seven different colours, giving it a wider color gamut.
DLP, which represents digital light processing, is a Texas Instruments technology. It uses mirrors and colour wheels to reflect and filter the projected light. For dwelling 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 individuals solely find out about single-panel DLP projectors.
The only downside of DLP projectors is what believers call “rainbow effects.” Client DLP projectors use clear coloration discs (half-color wheels) rotating in entrance of the lamp. This disk, divided into several major colors, reconstructs all the ultimate colors. The place of these major colours is just like the slice of pie. Relying 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 eight segments have a number of white. The smaller the section, the less the turntable, the stronger the power of the eyes to disassemble the color. This means you typically see something like a rainbow, especially in bright areas of the image. Thankfully, not everybody sees these rainbows. So earlier than shopping for a DLP mini projector, remember to check out some video sequences.
Some viewers discover the tweeter of the color wheel an annoyance. Nevertheless, the driveline can be designed to be silent, and a few projectors don’t produce any audible color wheel noise.
The edges 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 a different, or how the curve seems in the image. In DLP projectors, the way to present this grey transition is by turning the light source on and off quicker in this area. Sometimes, inconsistent dither artifacts can occur in colour conversions.
Because one pixel can’t render shadows precisely, error diffusion artifacts caused by averaging shadows on different pixels
