No, there are two types. The older DMD displays found in late 80's and 90's pins have plasma DMD's. These are prone to degassing, and to some extent, burn-ins. Newer DMD's usually consist of LEDs. These might get slightly less bright over time, but should not really fail over time.
Quoted from Mitch:I've seen many led dmds have a led go bad and then a whole row always stays slightly lit. It's become g more common even in low play huo games.
Ok, I was talking about LED's in general I guess. Didn't know they could fail like that. Thanks!
