What about the
neat-looking amber electroluminescent panels that Planar
make? I always thought they looked cool.
Planar amber EL panels are nice (I have an ELT320), but I don't think
they ever scaled that down to the 1-line size like some of intelligent
LED displays. They probably didn't need to move into the range that
VFDs have occupied very successfully, if I had to guess.
What about the Panaplex 7-segemnt gas discharge displays?
Or the gas discharge dot-matrix displays that include their own 'sift
register)? You know how you can step a discharge round a dekatron tub,
well at least one mnufacturer made a dot matrix display on that
principle. You applied the next column of dots to the electrodes at one
end, then sequenced the 2 control electrodes, and all the dots moved
along one cloumn.
