years? Is that the case?
From what I've read, the lifetime thing's been
pretty much licked on
modern units. Planar apparently produced quite a few
full-color
displays for DOD, but then got derailed when DOD decided to adopt TFT
for displays.
The "cool neon" EL wire really does run the phosphors quite "hot" and
I've heard that they will begin dropping in brightness after a couple
hundred hours. Apparently, however, some of the white LED phosphor
technology is migrating to EL use, as I'm starting to see superbright
white wire now.
I'm surprised that Grid Compass 1101 owners haven't popped up to
volunteer that their systems use an EL displayl. How's the
brightness holding up?
Sharp apparently makes EL displays, but they're hard to find.
Here's a datasheet for a 640x480 unit:
