LCD projector
From Wikipedia, the free encyclopedia
An LCD projector is a type of video projector for displaying video, images or computer data on a screen or other flat surface. It is a modern equivalent of the slide projector or overhead projector. To display images, LCD (liquid-crystal display) projectors typically send light from a metal-halide lamp through a prism or series of dichroic filters that separates light to three polysilicon
panels – one each for the red, green and blue components of the video
signal. As polarized light passes through the panels (combination of
polarizer, LCD panel and analyzer), individual pixels can be opened to
allow light to pass or closed to block the light. The combination of
open and closed pixels can produce a wide range of colors and shades in
the projected image.
