Buying A CRT Rear Projection TVThe television industry has evolved significantly, especially over the last few years. While a couple of years ago our parents had to decide whether to buy a color TV set or a cheaper, black and white set, nowadays you have other questions: would your next TV be an LCD, a plasma set or a big screen CRT rear projection tv. Other questions when you have to buy a TV are its size, the image's diagonal, its supported resolution and its technology. Each technology used to manufacture television screens has its pros and cons, so you should choose carefully your future TV set according to your needs. The latest technology in the domain of very large TV sets is the projection television screens. It may sound complicated, but they are exactly what their name announces: the image is projected from behind the actual screen. If you like, it is an evolution of the classic projectors adapted for your TV screen. Manufacturers make use of three technologies for their projection TV screens: CRT, LCD projection sets and DLP screens. However, they are built around the same basic idea: using a complex set of mirrors, lenses and projection beams, the images appears on the screen itself. CRT rear projection TV sets are the next step in the evolution of the cathode ray tube (the grandfather of today's television sets and computer screens). Being the oldest projection technology, it shares some of the manufacturing details with the normal CRT screens. Actually, they make use of three CRT, as there are three primary colors used to produce the colors on the screen. As CRT rear projection TVs are based on classic CRTs, they are the cheapest projection screens on the market and they offer very large resolutions. Their main advantages are the screen size. While other projection TVs start at lower diagonal sizes, the smallest CRT rear projection TV set you can find has a 42" diagonal. CRT rear projection TV sets also offer great resolutions and image quality and they are perhaps the most suitable rear projection TVs for watching 1080p High Definition movies. However, you may experience a lower image quality if you watch classic VSH tapes or regular cable TV channels. Indeed, some newer rear projection technologies (such as DLP or LCD projection TVs) offer a better image quality, but at much higher prices. You can also use CRT rear projection TV sets for static images, as they are least prone to burn-in problems (when a certain static image is displayed for a longer period on a screen). Because CRT rear projection TV sets are built around a time-tested technology, they offer you the greatest life span. If you respect all the manufacturer's advices and instructions, you can expect your CRT rear projection TV set to last up to 10 or 15 years. The main drawbacks of CRT rear projection TV sets are that because they are built around classic CRTs, they are very heavy and occupy a lot of space in your living room. |
