Different Types Of Home Theater Projectors

The main benefit of having a home theater is surely the luxurious viewing experience it affords us. It is always nice to possess something which the majority do not have. The unique ambience of cinemas can be captured completely(even with the popcorn if you choose!), minus the crowds which is usually a bonus, and your favorite movies can be watched with friends and relatives in comfort. Home theater video projectors are the main component around which the home theater system runs.

There are currently three kinds of video projector technology in use. They are LCD, CRT and DLP. As well as these, there are certain modifications also available, based on the technology used for the above three.

The first sort of video projector is the LCD projector, which stands for Liquid Crystal Display. An LCD projector primarily operates by delivering a strong light source through a transparent LCD chip comprising of individual pixels, which exhibits the moving video image. This image is subsequently projected through a lens to a big screen.

During the early years of video projectors, television expertise was centered on what’s known as Cathode Ray Tube technology, or CRT. Cathode ray tubes are simply used to produce a television image.

Three small CRTs with a single unit meant for each principal color, and a lens to magnify the light, helps in the projection of a color representation against a big screen especially in a dimly lit room. A CRT projector can create superior high-resolution images. This can be achieved with the help of the right combination of video processing circuitry, CRT size, and lens.

The third type which is becoming increasingly popular is the DLP, or Digital Light Processing projector. This type of projector is very similar to the LCD in that the real image is also exhibited on a chip.
