Gas-plasma display
Display that is a collection of neon gas materials between two plates. Each plate contains a conductive print, one with a horizontal and the other with a vertical. Gas-plasma displays are found in older portable computers, however, because of advances in portable LCD technologies and the power requirements, gas-plasma displays today are only used with large displays. These displays can range anywhere to 42 to 60-inches and can cost anywhere from $8,000 to $30,000 and higher.
