. Plasma displays are made, quite literally, of tiny cells full of ionised gas. Early types were filled with neon which glowed the characteristic red-orange when a high voltage was applied, creating the bright orange flat panel displays found in early 90s laptops.
This image reveals the structure of the Pioneer PDP-V402 plasma display panel. There a mesh over the front of the matrix of cells to provide electrical conductivity and not great fill factorFull-colour plasma displays are filled with a gas mix including mercury which, as in a fluorescent tube, emits ultraviolet radiation when excited. Notice the higher fill factor and lack of meshThe problem was, it was not a lot better than the best LCDs, because LCD was a maturing technology. Plasma as a full-colour display dates back….
