Hello, I obtained these displays. What are thay called? Are they just normal LED segments? or something that requires special treatment? Any sites with info on these?
The display itself seems to be between two glass plates.
It's a VFD (Vacuum Flourescent Display), it's not 'between two glass plates', the insides are sealed in a vacuum - it's essentially a valve (or vacuum tube, depending where you come from).
Like any valve, they require a heater supply and a fairly high HT supply (usually 60-90V), and (again like a valve) you control them by applying voltages to grids and cathodes.
