Rear Projection is a TV set in a "boxy" cabinet and having an optical system consisting of (for color TV, usually three) small CRTs or LCD panels or other picture forming elements, together with lenses and mirrors and perhaps a projection lamp used to project a picture against the back side of a translucent panel that serves as the viewing screen.

RPTV's typically have screens ranging from 35 to 70 inches in size. The same concept is also used for small film and viewgraph viewers.

The term "rear-projection" comes from the fact that the image is projected and reflected onto the screen from behind the screen, unlike traditional video and film projection in which the projector itself is placed in front of the screen, such as in a movie theater.

Plasma and LCD flat panel televisions seem to be all the rage these days, with growing numbers of consumers reaching into their pockets to buy the stylish sets, they are still out of reach of most average household budgets. As a result, the rear-projection TV (also referred to as an RPTV), with its lower pricing yet high performance, is taking center stage in the consumer television market.

The Elements Of Rear-Projection Television--->
There are five basic elements in the construction of a rear-projection television. First, there is the type of projector technology used to produce a video image. Second, the type of lens assembly used to magnify the projected image. Third, the necessity to employ a mirror to reflect the projected image. Fourth, the screen upon which the reflected image is presented. Fifth, the sealed box that contains all of the previous elements.

well Kajol, Televisions in the 40" to 80" diagonal screen sizes are possible with rear projection TVs and are now available with higher resolution ,Enormous televisions and home theaters used to be a real luxury. But in the last few years, many people have started to view large screens with great pictures as necessary for watching TV and movies at home. Although old-fashioned cathode ray tube (CRT) TVs can provide a great picture, they can't support the screen size that people look for today. Projection TVs can provide a much bigger picture than CRT sets can, and front- and rear-projection models can suit a range of rooms and budgets.

RPTVs often weigh less at a given screen size (only a few tip the scales at more than 100 pounds). And especially for screens larger than 50 inches, they frequently cost less. Rear-projection TVs come in multiple flavors, however; here's what you need to know to sort through the alternatives.Today's microdisplay technologies--DLP, LCoS, and LCD--deliver superb high-definition pictures from cabinets much smaller and lighter than those of the CRT rear-projection TVs of yesteryear.
