Led projectors

Listing ID #1791311

An LCDLED 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, LCDLED (liquid-crystal display)(Light Emitting Diode) 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, LCDLED panel and analyzer), individual pixels can be opened to allow light to pass or closed to block the light.
