If you have though of changing from your old Tv and move to the wonderful world of HDTV televisions you may find that there are many types of screens. Every type of screen has its own pros and cons when it comes to image quality. In fact, the differences between them are so noticeable that people that are HDTV savvy can easily differentiate them without having to look at product manuals. So which one is the best one for you? That question can only be answered by you. Here you will read about the pros and cons of the different technologies that are used when manufacturing HDTV televisions. One of the most common technologies is Plasma. HDTV televisions with Plasma screens were very abundant during the first years of high definition Tv. Plasma Tvs project warm beautiful colors and dark blacks. Dark blacks translate into high contrast and very defined images. They also have very fast refresh rates. Older models did had a short lifespan and were prone to image burn in. In a sense, Plasma HDTV televisions have the better image quality than most HDTVs but lose screen brightness as they get older. They also consume more energy. The leading technology in the high definition world is LCD. LCD means liquid crystal display. Colors are usually very bright on them. These sets can last for many years with the proper treatment. LCD are not prone to the problems that Plasma sets are and do not require as work to maintain in optimal conditions. However, the quality of the Tv is very dependent on the model in question. Some of these sets can easily rival the image quality of a Plasma screen while others have suffer from unwanted artifacts in their image. In general, most LCDs made by the big brands are excellent. So as a general rule stick with the known brands if you decide to buy one of them. The other leading technology is known as DLP. There are two types of DLP technologies one uses one micro chip and the other uses three. Usually DLP is used to manufacture rear projectors and are of great value of the money to those that are interested in purchasing an huge screen. When it comes to image quality, DLPs are not to good compared to the other two leading technologies.It is strange that even if these technologies are very advanced, they can not match the contrast and colors of CRT, the oldest television technology to date. CRT is still used in some small conventional televisions. It was used to manufacture HDTV sets but, due to their heavy weigh and the fact that they take a lot of room made manufacturers change their mind about this technology.
