A gas-plasma display is a technology that is a collection of neon gas between two plates. Each plate contains a conductive print; one is horizontal, and the other is vertical. These displays ranged from 42 to 60-inches and originally cost anywhere from $8,000 to $30,000 or higher.
Although gas-plasma technology was found in older portable computers and large displays, like the CRT television, it is now obsolete. Today, because of advances in LCD technologies and the power requirements of gas-plasma displays, nearly all flat panel screens are LED backlit LCDs.
