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 LCD
panels are key elements in the production of the three RGB basic colors.
2. Images of high ratio contrast are produced. Usually the image contrast
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.
