Hi we all know little bit about all things which are use in the audio visual Field.
know we see the little bit about projectors.

There are many types of projectors used in video conferencing for the display purpose.

There are main three types of projectors ...... !

1> LCD




LCD projectors start with a source of light (lamp) and split the light into three beams. Each beam passes through its own LCD panel. The LCD panels each have hundreds of thousands of tiny pixels the higher the resolution the more pixels.Data determines whether light is allowed to pass through each.

2> DLP



The vast majority of DLP projectors use a single monochrome DLP chip (officially DMD for "Digital Micro Device), and the aforementioned spinning color filter wheel to generate colors. Unless specifically noted, when this series of articles refers to DLP projectors, they are discussing single chip models

3> CRT



The full form of CRT is(Cathode Ray Tube)When video projectors first arrived on the scene, television technology was based on the Cathode Ray Tube (CRT), on which the viewer sees the television image. Three small CRTs (one for each primary color), coupled with a light magnifying lens, can project a color image onto a large screen in a darkened room. With the proper video processing circuitry, CRT size, and lens combination, a CRT projector can produce excellent high resolution images.
