LCD projector with screen.
- LCD gives a sharp image which is better in high detail data applications
- LCDs tend to have greater color saturation which increases perceived overall brightness
- LCD projectors are more “light efficient” than DLP projectors, meaning that given the same wattage of the lamps, an LCD projector will produce a brighter image

An LCD projector is a type of video projector that displays video, pictures, or computer data on a screen or other flat surface. It is the modern equivalent of a slide projector or overhead projector. An LCD projector is a type of video projector that displays video, pictures, or computer data on a screen or other flat surface. After that It is the modern equivalent of a 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 separate the light into three polysilicon panels – the red of the video, One signal each for the green and blue components.
After all As polarized light passes through the panels (a combination of polarizer, LCD panel and analyzer), individual pixels can be opened to allow light to pass or closed to block the light. As a result, The combination of open and closed pixels can produce a wide range of colors and shades in the projected image.
In 1989, Projectavision, Inc. was awarded the first Defense Advanced Research Projects Agency (DARPA) contract – for US$1 million – to propose that the United States High-Definition Television (HDTV) standard should use digital processing and projection. With Leon Shapiro as a member of the National Association of Photographic Manufacturers’ Standards subcommittee, IT7-3, Dolgoff co-developed the worldwide ANSI standard for the measurement of brightness, contrast and resolution of electronic projectors.
After all In 2004 and 2005, LCD front projection began to make a comeback with the introduction of dynamic iris and other modifications that have reportedly improved contrast to similar levels of DLP.
Since 2005, [9] the only remaining manufacturers of LCD Projector with screen to LCD projectors are the Japanese imaging companies Epson and Sony. Epson owns this technology and has branded it as “3LCD”. To market 3LCD projector technology, Epson established a consortium called the “3LCD Group” in 2005, with other projector manufacturers licensees for 3LCD technology which is use it in their projector models.
