These displays are from mid 80s to mid 90s and they look cool, but they are rather expensive ($100 a piece..). The lib was developed and tested with displays salvaged from some equipment. You see them mostly in HP printers, medical equipment etc.

Some info can be found here and here.

Datasheet is here
