What is Plasma display?
[[File:Plasma display.jpg|thumb|300px|right|A plasma screen television in 2003. These televisions are light-weight and save space]] Televisions with''' plasma display panel (PDP)''' are much thinner than [[cathode ray tube]]s and are usually higher definition. Only a few televisions use a PDP. Plasma screens are made of two sheets of glass with two gases stored between the sheets. The gases are [[xenon]] and [[neon]] and they fill thousands of tiny chambers, or spaces. Behind each space are a series of red, blue and green [[phosphor]]s that give off light when struck by radiation. When electricity connects to the plasma chambers the colored phosphors produce the right color on your screen. They work in a very similar way to [[fluorescent lamp]]s used for lighting. Plasma screens have been in use since 1964 but only two colors could be produced then. Now we have [[high definition]] Plasma screens up to 150 inches in size. In the early 21st century fewer plasma screens were made as people bought more [[liquid crystal display]]s. == Advantages == 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. One of the big advantages is the space saving. The problem with old cathode ray tubes is that they needed a lot of space so that the rays can fire upon all areas of the screen. The wider the screen, the larger the volume of the television would be. The average Plasma television is around 6 to 8 inches deep. Moving your Plasma onto the wall can really increase the amount of floor space and they can be looked at from almost any point in
