The video projectors are the need of the hour in the high tech world of this technologically advanced that most of the tasks is performed by means of various technological tools.The video projectors perform their function by means of detection and recognition of the video signal and then presents the image through a lens system. These projections are very useful in the case of professional presentations and classroom and with the progress of time, technological tools developed further facilitated the efficient operation of video projectors. There are certain ways that are the predominant technology used by video projectors for good quality and perfect projection image.

Techniques previously determined that they like the oil-film projectors as Eidophor and Talaria, Schmidt-CRT, ILA or valves clear clear picture of the amplifier were used for the facilitation of operations of the projectors.

However these were outdated and newer techniques are nowadays in use. The first among them would be the LCD projector that works through the gates, clear LCD and is the most prevalent technology used for projection.

The projector CRT works by means of cathode ray tubes and is of three colors blue, red and green. Is one of the oldest of the projection technologies used today and is favored because of its low maintenance costs. Also offers the largest screen size if paid accordingly.

DLP technology by Texas Instruments is used by the DLP projector that contains the drives or digital micromirror DMDs that are microfabricated light valves, varying one – three of number and function through a color wheel and turn the mirror that allows the modulation of color.

The video projection is also possible with the help of LCOS projectors that use the crystal clear on the technology of silicon and the same technique is also used in the operation of D-ILA JVC direct-drive image light amplifier, which in turn Gain is another way of video projection. The major suppliers include Samsung, Panasonic, Sony, Toshiba, Hitachi, the Sharp, Mitsubishi.
