Everywhere says it's electroluminescent. I mentioned "burning out" instead of burning in. I know it's not the most technical term, but I mean LEDs failing in displays. In your speedometer for your car, either the whole display with fail (probably the circuit is broken) or the whole thing works, because it's one EL panel behind a translucent screen.

Also because of the nature of an ELD's components being static, (they radiate when a charge is applied, in a way very different to the phosphors that move around in CRT and plasma screens) I don't think it's possible for them to burn in.
