A plasma TV is a type of high definition display that, along with LCD TVs, slowly replacing standard cathode ray televisions that have been the standard for a number of decades. A plasma TV gives very vibrant colors and crisp images. The high quality is more noticeable when high definition broadcasts are watched from the plasma TV.
A plasma TV has an aspect ratio of 16:9, which is the same ratio for widescreen movie formats. In contrast, a standard definition CRT TV has an aspect ratio of 4:3, which is like a box. One of the most popular features of a plasma TV is the flat screen that allows a user to mount it on a wall like a picture frame. The vibrant pictures given by the plasma TV is also complemented by the very large sizes of the screens. There are models that range from 32 inches to screens as large 52 inches. The very big screens mean it is a great addition to a home theater. All one needs will be speakers and an A/V receiver to deliver 5.1 surround sound.
Plasma TVs, as its name implies, employs plasma (considered the fourth state of matter) in producing pictures. The pixels that are used inside the panel contain three minuscule containers of an inert gas – usually neon or xenon. The pixels are sandwiched between two plates that are electrically charged. An electrical current is passed on to the thousands of pixels to either produce red, green or blue colors in order to produce the image.
