The motors tilt their mirrors up to 20 degrees at incredible speeds. This allows the mirrors to modulate light from a lamp, and send the "modulated signal" out through a lens, on to a screen. The most amazing part of DLP micro mirrors, is the scale of size. The 480,000 mirrors (actually 580,000 are used), hinges and motors are packed onto a "wafer" a bit larger than your thumbnail. LCD: LCD stands for liquid crystal display and comes in many forms, sizes, and resolutions. Its primary purpose is to present a digital image for viewing. A common use of LCDs is as a display on a notebook computer. Until recently, it was tough to find a decent 1,000-lumen projector that listed for less than $4,000. Now, you can pick up new 1,000-lumen LCD that the 6.6-pound projector builds on award-winning display technology to provide improved video imaging in a lightweight, easy-to-use design. Introduced at three 0.7-inch LCD display panels produce a native SVGA (800 x 600) resolution and a reported contrast ratio of 400:1.

The also uses resizing technology that makes the compatible with resolutions from VGA (640 x 480) up to XGA (1,024 x 768), says The projector is also HDTV-ready and supports popular digital video signals, such as 480i, 480p, 720p, 1080i and 1080p. A member of of travel projectors, the is about 1 pound heavier than its series mates, the As a member of the line, the features picture-in-picture technology, 15-degree digital keystone correction, electronic zoom, multifunction remote control and onscreen help features. The projector''s lens also retracts to protect it during transport. Our Value Series projectors have been incredibly popular among customers and the attractive prices offered in those models have definitely opened the doors to a lot of people who thought they could never afford a high-performance projector,""Now that we''ve boosted the performance on these models while maintaining affordability,

Lamp life is commonly discussed in terms of " Half Life". This simply means the manufacture has set a limit on what they feel is the quality life of the lamp. If the lamp half life is 2000 hours, the lamp will generally last much longer although the brightness of the image may deteriorate. For example, on an LCD projector, the lamp half life is generally 2000 hours. The image brightness is normally above 85% of the original brightness up to 2000 hours. After 2000 hours you may see a drastic reduction in brightness. DLP projectors normally have less of a life and the brightness generally starts deteriorating before the half life. DLP & LCD Digital Light Processing (DLP): The commercial name for this technology from Texas Instruments (TI): The technology inside is often referred to as either "micro-mirrors", or DMD: It works this way: build a few hundred thousand tiny mirrors, and line them up in 800 rows of 600 mirrors each. Now attach a hinge to each of those 480,000 mirrors. Attach each of those 480,000 hinges to its own very tiny motor! Power each motor with electrostatic energy!
