Rear Projection TV
If you're like me and really into your television then it goes without saying that the bigger the screen the better. Yes, if we're going to watch television then let's do it properly - enter the Rear Projection TV.
If you feel the same way then you're probably thinking about upgrading your TV and getting your hands on one of the big televisions that are available these days. How do I know that? Because I'm in that state constantly - I'm always considering a bigger television.
Although most of the current buzz is around flat screen or LCD screens, recent improvements in technology are now making a rear projection TV an affordable option for many people. Advances in the quality of the picture using rear projection TV have made them a reasonable and not too expensive alternative choice to the big flat screen televisions we usually see.
So what exactly is a rear projection TV? Well, the term comes from the fact that the rear projection TV projects the image onto the viewing screen from behind. It's a bit like being in the movie theater except the projector is behind the screen instead of in front of it. The picture gets displayed onto the screen from behind and you see the effect of it showing through the screen from the other side.
Improvements in the manufacturing technology of rear projection TV have provided us with a variety of models that have never been available before. Your normal television set probably uses a CRT - cathode ray tube - to display or project the image. Some rear projection TV use a similar technology, buth these televisions are quite large when you start to increase the screen size. But, there are picture quality issues you need to consider. For instance, you might get improved blacks and colors but if the image is not exactly aligned then this type of rear projection TV can produce some incorrect color blending.
Another type of rear projection TV is based on a LCD - Liquid Crystal Display. Don't get these mixed up with the LCD used in a flat panel screen though. This LCD type of rear projection TV can offer many advantages including the size of the TV itself, which is quite small in comparison to the older CRT models. There is higher contrast and brightness in the LCD type rear projection TV, but as with other models there are some disadvantages. Without getting too technical, the output on the LCD type can sometimes look a little blurred or fuzzy due to the resolution.
If you're really going for it you need to take a look at something called DLP, or Digital Light Processing technology. This is used in the newer rear projection TV technology. It's not the same as CRT or LCD, but rather uses a mirror to reflect and display the image. The end result is that you get superior picture quality without many of the inherent disadvantages of the other types.
So, how do you get hold of one of these? You need to find yourself a reputable and trusted dealer, and then explain that you're interested in a DLP rear projection TV. They'll no doubt show you other models of rear projection TV and explain the pros and cons of each.
If you already know which model you want, then you'll most likely get the best deal online. Take a look at what's being offered at the moment and keep your eye out for specials. I say there's absolutely no reason not to have the best viewing experience you can, and a rear projection TV could be just the thing.
