plasma display

[ratstar]

Has anyone ever seen someone making a display out of spark gaps?
It would be similar voltage to a neon bulb no?

Would be quite spectacular.

Hello,

Plasma displays do exist:

But I actually mean *spark gap* as in that kind of plasma. Just the electricity in the air.

Is it actually the same thing?

Hello,

From the give page:
A display in which sets of parallel conductors at right angles to each other are deposited on glass plates,
with the very small space between the plates filled with a gas;
each intersection of two conductors defines a single cell that can be energized to produce a gas discharge forming one element of a dot-matrix display.

Oh I see. but its just not as zany as doing it in the open air like a spark plug.
