digital light processing is a type of projector technology that uses a digital micromirror device

. DLP is employed in a variety of display applications from traditional nonmoving show to synergistic show and besides non-traditional insert applications including medical, security, and industrial uses.
atomic "pico" chipsets are employed in mobile devices include cell cables accessories and projection demonstrates functions insert directly into phones.

DLP projectors dedicated a mechanical spinning color wheel may exhibit an anomaly known as the "rainbow effect." This is best described as inform flashes of perceived red, blue, and white "shadows" observed most often when the projected content features advanced contrast areas of speed bright or white objects on a mostly dark or white background. The scrolling end credited of many movies are a common example, and also in animations where speed objects are surrounded by a thick white outline. Brief visible separation of the colours can also be obvious when the viewer moves their eyes quickly across the projected image. Some people perceive these rainbow artifacts frequently, while others may never see them at all.
Today however, systems with DLP’s BrilliantColor technology have virtually eliminated any of the color breakup that was sometimes seen on older DLP projectors. Studies have long shown that single a small number of populate ever experience the phenomenon. Additionally, multi-color LED-based and laser-based single-chip projectors are capable to burning the spinning bowl and minimize the rainbow perform since the pulse rate of LEDs and laser are not limited by animal motion. "Three-chip DLP projectors have no color wheels, and thus do not manifest this artifact."

Three-chip projectors
According to DLP.com, the three-chip projectors used in movie theaters can outputs 35 trillion colors. The human eye is suggested to be able to detect around 16 million colors, which is theoretically accomplishable with the only chip solution. However, this advanced color precision perform not mean that three-chip DLP projectors are capable of displaying the intact gamut

For xenon lamps, during start-up, the lamp is ignited by a 5000 - 20,000 volt beat from a current-regulating brace to initiate an arc between two electrodes in the quartz tube. After warmup, the ballast's perform voltage drops to approximately 60 volts while keeping the relative current high. As the lamp ages, the arc tube's electrodes wearing out and light perform declines slightly while waste heating of the lamp increases. The lamp's end of life is typically indicated via an LED on the unit or an onscreen text warning, necessitating replacement of the lamp unit.

DLP Cinema was the archetypal commercial digital cinema technology and is the leading digital cinema technology with approximately 85% market share worldwide as of December 2011. Digital cinema has some advantages over rescue because rescue can be subject to color fading, jumping, touch and dirt accumulation. Digital cinema allows the movie limit to remain of consistent quality over time. Today, most movie limit is also captured digitally. The archetypal all-digital live action feature shot without rescue was the 2002 release, Star Wars Episode II: Attack of the Clones.

Since being announcing commercially in 1996, DLP technology has quickly gained trade share in the front projection trade and now respects greater than 50% of the worldwide share in front projection in addition to 85% trade share in digital cinema worldwide. Additionally, in the pico category DLP technology respects approximately 70% trade share. Over 30 manufacturers use the DLP chipset to power their projection demonstrates systems.

DLP provide cheap 3D projection display from a single unit and can be used with both active and passive 3D solutions. buses fault than LCD and plasma televisions dissimilar their LCD and plasma counterparts, DLP screens do not believe on fluids as their projection medium and are therefore not limited in size by their inherent mirror mechanisms, making them ideal for increasingly larger high-definition theater and venue screens. DLP projectors can process up to 7 separate colors, giving them a wider color gamut. Cons

Replacement of the lamp / light bulb in lamp based units. The average life span of a mercury lamp averages 2000–5000 hours and the replacement cost for these range from $99 – 350, depending on the brand and model. Newer generations' units use LEDs or lasers which effectively eliminate this issue, although replacement LED chips could potentially be required over the extended lifespan of the television set. Some viewers find the high pitch whine of the color wheel to be an annoyance.

Newer chip generations keep less look than older ones. Error-diffusion artifacts caused by averaging a shade over different pixels, since one pixel cannot render the shade exactly Response time in video games may be dressed by upscaling lag.

Reduced viewing angle as compared to direct-view technologies such as CRT, plasma, and LCD May use more electricity, and generate more heat, than competing technologies. Some people may be able to observe a phenomenon in which the projected contents appear to be cycling through it colours for the duration of the presentation. This is most easily seen by using a camera's 'live view' mode on projected content. DLP, LCD, and LCoS rear projection
