Like many people, you may be filled with a burning curiosity to understand what makes a rear-projection TV perform its magic. Actually, it’s pretty much done with smoke and mirrors. (Just kidding - if you have smoke appearing out of your rear-projection TV you have a problem!)

How it works is this: a video picture is projected via a projectors lamp inside the television, then a system of mirrors and lenses redirect the image onto the inside surface of a translucent screen.

When this technology was first introduced, CRTs (cathode ray tubes - the things that made traditional television sets so bulky) were used, and it worked very well. The down side to this was that the tube made the chassis extremely heavy and, typically, a floor standing cabinet was needed to house it.

Eventually,In the end, as screens grew in size, and the industry began to adopt the new, wider 16:9 aspect ratio (the ratio of height to width), those old CRT cabinets were gradually replaced by new models which deliver high quality pictures in light, compact enclosures.

Rear projection TVs come ready with high definition capability nowadays. This is a very important point - they are equipped to handle everything HDTV broadcasting and discs can demand of them. And make no mistake - High-Definition TV will produce wide screen images in much greater detail and clarity than we are accustomed to from traditional broadcasting. As well as tuners for analog and cable TV - not to mention being able to receive unencrypted digital cable signals without the need for a set top box - HD tuners are included in all modern RPTVs, which means they can take full advantage of all the exciting broadcasting improvements which are just around the corner.
