A LCD projector or Liquid Crystal Display projector is basically a modern analogue version of the slide projector or overhead projector. LCD projectors are used for projecting videos, images or computer outputs on a screen.

LCD projectors use small Metal Halide lamps that can send a very strong light through a prism to cast the projection on any flat surface. LCD projectors tend to be of smaller size and more portable when compared with other type of projectors. However, LCD projectors would still be the best in terms of image quality, particularly when projected against a blank white or grey surface, or when a projector screen is used.

Unlike CRT (Cathode Ray Tube) projectors, the LCD projector does not function according to the traditional projection-tube system. The LCD projector contains three separate LCD glass panels, red, green and blue for the three components of video signal. The LCD chip is transparent, and when a powerful light source is passed through it, each individual pixel transforms the light and projects the image or data through a lens onto the screen.

The miniature size of the LCD chip enables the manufacturers to create compact and portable LCD projectors. These compact, portable projectors are certainly ideal for mobile professionals. Most LCD projectors are also typically capable of producing 2,000 to 2,500 ANSI lumens brightness with 1024 x 768 VGA resolutions, resulting in better image quality. LCD projectors are also relatively cheap compared to CRT projectors, and they consume less energy.
