There are mainly two kinds of projectors, video projectors and transparency projectors. Under the video projectors, there are four kinds. These are the LCD projector, CRT projector, DLP projector and LCOS projector. As for the transparency projector, it has the movie projector, slide projector, and overhead projector.
An LCD projector is also known as a liquid crystal display. It uses a metal halide lamp in order to send light through the LCD panels so as to display images. It is the modern slide projector and overhead projector of today.
CRT projectors are popularly known as video projectors. It utilizes high brightness picture tubes or CRT so as to create an image. The created image is then enlarged and focused with the use of a lens. This lens is placed behind the face of the CRT.
A DLP or digital light processing device uses a Digital Micromirror Device (DMD). It is a small memory chip which adjusts the electromagnetic mirrors for every pixel in the image. It is also good to use even in rooms that are lit.
LCOS stands for liquid crystal on silicon. It is known as a micro projection technology device which is used for televisions. Like DLP, it makes use of reflective technology but has liquid crystals instead.
Under the transparency projector, the movie projector uses films on a reel to form moving pictures. A slide projector also enlarges photographic slides on the screen. The overhead projector also enlarges images of pictorial or written material on a transparency that is placed underneath the projector.
