As a spare part from whatever it came out of, such items are rarely standard - there is an American Company (who's name escapes me at the moment) who lists a wide range of displays. They actually list a display we were trying to source (the product manufacturer refuses to supply spare parts or service information), but we never got any reply to emails, and we even tried phoning the number on their website (during working hours in their time zone) but they never answered. In the end we gave up.
