Like many people, you may be filled with a burning curiosity to know what makes an RPTV do its magic. Well, it’s pretty much done with smoke and mirrors. (Just kidding - if there is smoke appearing out of your RPTV you have a serious problem!)
First, a video image is projected via a projectors lamp inside the box, then a system of mirrors and lenses redirect the image onto the inner surface of a translucent screen.
When this technology was first developed, CRTs (cathode ray tubes - the things that made old-fashioned TVs so bulky) were used, and it was very successful. The only problem here was that the tube made the chassis very heavy and, usually, a floor standing cabinet was needed to house it.
So, as screens grew bigger, and the industry began to take up the new, wider 16:9 aspect ratio (the ratio of width to height), those old CRT boxes were gradually replaced by new models which deliver high quality pictures in light, compact cases.
Rear-projection TVs have built-in high definition capability nowadays. This is a very important point - they are equipped to handle everything HDTV broadcasting and discs can throw at them. And make no mistake - High-Definition TV will provide wide screen pictures in much more detail and clarity than we are accustomed to from traditional broadcasting. As well as tuners for cable and analog TV - not to mention the ability to receive unencrypted digital cable signals without requiring a set top box - HD tuners come as standard with modern RPTVs, which means they can take full advantage of all the broadcasting innovations which will be coming soon.
