DLP Projectors
The DLP Projector is a front projector that uses the same DLP technology used in the DLP TV (which is a rear projector).
In DLP projectors, a powerful lamp passes light through the color wheel and reflects off the DLP projector's DMD chip. Expensive models use a three-chip configuration for better contrast cohesion, especially during motion. The DLP projector, like all front projectors, must be positioned behind or above the viewing with an unobstructed ray to a screen in front. The DLP projector is fixed pixel display so it has a finite number of pixels which is measured as resolution.

Sponsor Links (what's this?)
- DLP projectors are lightweight and portable.
- Fixed pixel display is sharp and high-contrast.
- The display area of a DLP projector can span from 40" to 250".
- DLP projector requires a dark room for optimal display.
- DLP projectors are cost prohibitive to the average consumer.
- Cooling fan overhead of viewing area could be distracting.
- Motion artifacts that appear as noise around high contrast images moving across the screen may be a problem for single-chip designs.
