Since white is more of a neutral color, white surfaces are best suited for natural color tones as such, white projection surfaces are more common in most business and school presentation environments. Perceived color in a projected image is a factor of both projection surface and projector quality. Even so, the best image quality is found using a blank white, grey, or black (which blocks reflected ambient light) surface, so dedicated projection screens are often used. Other technologies, such as Digital Light Processing (DLP) and liquid crystal on silicon (LCOS) are also becoming more popular in modestly priced video projection.īecause they use small lamps and the ability to project an image on any flat surface, LCD projectors tend to be smaller and more portable than some other types of projection systems. These lamps also have the ability to produce an extremely large amount of light within a small area current projectors average about 2,000 to 15,000 American National Standards Institute (ANSI) lumens. Metal-halide lamps are used because they output an ideal color temperature and a broad spectrum of color. The combination of open and closed pixels can produce a wide range of colors and shades in the projected image. 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. 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.
