The Three Most Popular Technologies that Are Used in HDTV Televisions
IF you have thought about getting rid of your old conventional tv set 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, motion and color projection. In fact, the differences between screen types are so noticeable that people that are HDTV savvy can easily distinguish from an LCD and a Plasma set without having to look at product specifications. So which one is the best one for you? That question can only be answered by you. In this article you will learn about the pros and cons of different technologies that are used when manufacturing HDTV televisions.
One of the most know technologies is Plasma. HDTV televisions with Plasma screens were very abundant during the first years of high definition tv. Plasma screens project warm beautiful colors and dark blacks. When it comes to tv sets, dark blacks translate into higher contrast and more sense of depth inside the image. They also have very fast refresh rates. Older models 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 they are heavy and can suffer from burn in if some precautions are not taken. They also require more energy to operate.
LCD HDTV televisions on their part are lighter. They are more energy efficient. When it comes to image quality, colors on LCD sets are very bright. When it comes to blacks, these Tvs do not have the solid dark blacks that Plasma sets have. Although, in recent times manufacturers have worked very hard to create models that can display dark blacks to help enhance the quality of the image. Some sets have a slow refresh rate that leads to image ghosting on fast moving scenes. Overall, LCD sets have a long lifespan and have a lower price than Plasma if you are looking for smaller sets. Be sure to read reviews since the performance of these high definition tvs varies from model to model.
There is another HDTV technology that goes by the name of DLP. DLPs are very cost effective compared to the other ones. Usually DLP technology is used to manufacture huge rear projectors. When it comes to image quality, this technology has lower image quality than the two mentioned above. There have been complaints about a rainbow effect that not all people but some are able to detect on images that are being created by a DLP projector. Some people have reported feeling dizzy after watching television on them.
There are more HDTV technologies available on the market. However these three technologies are the ones that dominate the market. Even with these more modern projection technologies the one that had the best image quality of all, and that is no longer manufactured for HDTV televisions was CRT, the same one that powered conventional television sets.
