digital light processing?

Answer 1

Digital Light Processing (DLP) is a technology used in projectors and video projectors. It was originally developed at Texas Instruments, in 1987 by Dr. Larry Hornbeck.

One application is DLP front projectors (small standalone projection units). DLP, along with LCD and LCoS are the current display technologies behind rear-projection television, having supplanted CRT projectors. These rear-projection technologies compete against LCD and Plasma flat panel displays in the HDTV market.

Pros
Smooth (at 1080p resolution), jitter-free images.
Perfect geometry and excellent grayscale linearity achievable.
Usually great ANSI contrast.
No possibility of phosphor burn-in.
Less "screen door effect" than with LCD projectors.
DLP rear projection TVs are smaller, thinner, and lighter than CRT projectors.
DLP rear projection TVs are considerably cheaper than LCD or plasma flat-panel displays and can still offer 1080p resolution.
The use of a replaceable light source means a potentially longer life than CRTs and plasma displays.
The light source is more-easily replaceable than the backlights used with LCDs, and on DLPs is often user-replaceable.
Using two projectors, one can project full color stereoscopic images using polarized process (because beams can be polarized).

Pros Projectors :
Exact pixels (due to the mirror technology) (Will not be "blurry" like a CRT projector)
No possible "burnout" with the picture like with LCD or CRT since the mirrors are a mechanical solution. On many LCD projectors will the visual failure be visible after only ~1000 hours due to the heat from the lamp which burns the LCD display
High contrast
Minimal separations between the pixels

Cons
In single-chip designs, some viewers are bothered by the "rainbow effect," explained above. Some viewers experience eye strain, headaches, and migraines when viewing DLP screens. Not as thin as LCD or plasma flat-panel displays (although approximately comparable in weight), though newer sets are thin enough to be wall-mounted. Some devices may have fan noise.
Silk screen effect "Screen door effect" (SDE) may be visible at close distance and/or with lower resolution models (720p resolution and lower). SDE can also be perceived as artificially sharp looking (due to dark gaps between mirrors/pixels which are high frequency content, not part of the image displayed) and not film-like.
Dithering noise may be noticeable, especially in dark image areas. Newer (post ~2004) chip generations have less noise than older ones. Error-diffusion artifacts caused by averaging a shade over different pixels, since one pixel cannot render the shade exactly. Mediocre on-off contrast compared to CRT reference.
Response time in video games may be affected by upscaling lag. While all HDTVs have some lag when upscaling lower resolution input to their native resolution, DLPs are commonly reported to have noticeably longer delays. Newer consoles such as the Xbox 360 and PlayStation 3 do not have this problem as long as they are connected with HD-capable cables.
Color rendition can be off, especially the bright reds and yellows when at maximum brightness. More mechanical than traditional CRT, LCD, plasma, and LCoS displays.
Poor viewing angle compared with direct-view technologies such as CRT, Plasma, and LCD.

Cons Projectors
The rainbow effect. Some people can feel sick even if they can't see the "effect".
More sensitive to "bumps/knocks" than an LCD projector since it uses a mechanical solution.

Answer 2

Yes, digital light processing!

(you need to be specific, what did you want to know?)

Answer 3

Yeah, sure. Why not?
