Neon bulbs work on the principle of voltage-induced ionization, creating a visible glowing plasma. If the applied voltage is high enough, around 60 to 80 V, electrons get knocked off the neutral ...

That sounds exotic compared to gasses, solids, and liquids, but it turns out that over 99% of the visible universe is plasma. Things like lightning, the sun, and neon signs are all forms of plasma.

Plasma displays were similar to the way neon signs work combined with the phosphors of a CRT. In fact, a plasma screen was like having a miniature CRT for each pixel (see CRT). THIS DEFINITION IS ...
