Plasma TVs have more pixels (tiny dots that when put together can create an image on a picture) per inch than the old fashioned cathode ray tube (CRT) screens so they can produce a much sharper image. In the old style of CRT screens the pictures were made up of lines. If you look closely at a Plasma screen you will not see any lines. You will find out that most Plasma screens have a wide screen option so you can see movies in the way they were intended for movie theaters. They are also ideal for the latest digital broadcasting methods.
