Magnavox - An Introduction To LCD Projectors

A projector is an apparatus for presenting an enlarged image on a screen from a transparency such as a photographic slide or a film. In a motion picture projector, each frame is held stationary at an illuminated aperture for a brief period, and then advanced by an intermittent sprocket or reciprocating claw, the light being cut off by a rotating shutter during the movement. The sound track on the film is reproduced at a separate sound head where the film is moved continuously at a constant speed.LCD projectors come with the capacity to deliver high-definition pictures with high pixel density. Most of the LCD projectors are compact and lightweight; most of the advanced LCD projectors even use two-inch poly silicon panels. These panels (an advanced LCD projector might have TFT panels) help to produce high-quality images with a high-definition quality of about 1,000 scanning lines.Most of the ordinary and average LCD screens have a screen ratio of 4:3. However, in some cases, an LCD might also have a screen ratio of 16:9. Images are projected on to a super-large screen. Some of the salient features of a compact, lightweight LCD projector are:1. The utilization of three high-definition two-inch poly silicon TFT LCDpanels are key elements in the production of the three RGB basic colors.2. Images of high ratio contrast are produced. Usually the image contrast is 400:1.3. A good LCD projector adds to the normal brightness by about 40% over most other conventional and ordinary LCD video projectors. These LCD projectors use a high-transparency LCD panel for the above purpose.For example, one of the recent high-quality LCD projectors is the Fujitsu LPF-D711 high-definition LCD projector for home theater.Projectors provides detailed information on Projectors, LCD Projectors, DLP Projectors, Video Projectors and more.
