LCD Projector, LCD Projector Bulbs, HD LCD Projectors
An LCD projector is a type of video projector utilized for displaying video, images or computer data on a screen or other flat projection surface. It is the modern equivalent to the slide projector and overhead projector used in the past.LCD (liquid crystal display) projectors usually contain three separate LCD panels, one each for the red, green, and blue components of the video signal. However single panel LCD projectors have been produced in the past. Light from halogen lamp, which outputs an ideal color temperature and a broad spectrum of color, is split by a prism into the three component colors.
Early LCD systems were often intended to be used with existing overhead projectors, built as a large "plate" that was put on the projector in place of the transparencies. This provided the market with a stop-gap solution in the era when the computer was not yet the universal display medium so that there was a market for LCD projectors before their current main use became popular.
In 2004 and 2005, LCD front projection has been enjoying a come-back because of the addition of the dynamic iris which has improved perceived contrast up to the levels of DLP.
Different display technologies have vastly different temporal characteristics, leading to claimed perceptual differences for motion, flicker etc.
LCDs have a constant (backlit) image, where the intensity is varied by blocking the light shining through the panel.
