What is a plasma TV?

Answer 1

A regular TV has a Cathode Ray Tube (CRT). A CRT is basically a large vacuum tube in which a electric beam emanating from a single point in the neck of the tube scans the face of the tube very rapidly which, in turn, lights up red, green, or blue phosphors on the tube's surface to make an image.

Plasma TV is based on flouresent light. It contains cells in the two glass panels that are separated by a narrow gap which is injected with neon-xenon gas and then sealed in plasma form during the manufacturing process. The gas is electrically charged at specific times when you use the TV. The gas then puts out groups of red, green, or blue phosphors called pixels (picture element). The reason Plasma TVs are flat is because you don't need a tube. Using a sealed cell, you eliminate the need for a CRT.

Answer 2

A plasma display panel (PDP) is a type of flat panel display common to large TV displays (80 cm or larger). Many tiny cells between just two panels of glass hold a mixture of noble gases (a group of chemical elements with very similar properties). The gas in the cells is electrically turned into a plasma which emits ultraviolet light which then excites phosphors to emit visible light. Plasma displays should not be confused with LCDs, another lightweight flat screen display using different technology.

Answer 3

if im right, it is used in the LCD screen of the television to enhance the working preduction. look here on http://www.wikipedia.com/

Answer 4

Thanks to plasma technology, a plasma television can be much thinner than a regular TV. Plasma makes use of tiny fluorescent lighted pixels to form an image on the screen.
