plasma display

A type of flat-panel display that works by sandwiching a neon/xenon gas mixture between two sealed glass plates with parallel electrodes deposited on their surfaces. The plates are sealed so that the electrodes form right angles, creating pixels. When a voltage pulse passes between two electrodes, the gas breaks down and produces weakly ionized plasma, which emits UV radiation. The UV radiation activates color phosphors and visible light is emitted from each pixel.

Today, Plasma displays are becoming more and more popular. Compared to conventional CRTdisplays, plasma displays are about one-tenth the thickness--around 4'', and one-sixth the weight--under 67 pounds for a 40" display. They use over 16 million colors and have a 160 degree-viewing angle.

Plasma displays are manufactured by companies such as Panasonic, Fujitsu, and Pioneer.
