You still see them in military/aerospace applications. Planar used to be industry leader in those, but it was acquired a couple of years ago by a Finnish outfit, Beneq. The business unit is called Lumineq: http://lumineq.com/ Thin-film EL displays are pretty cool. They're transparent. Like all modern EL displays, they're pre-patterned with display elements. --Chuck
