This works with the plasma plates.
The electricity leaving the discharge
tube will follow the path of least
resistance in the shape of numbers
with the help of electromagnets
behind the display.
Also, available in flashing 12:00.

Plasma discharge controlled by shaped wires

Nixie tubes use shaped wires to control the "path" of the plasma. [oldvan, Oct 05 2004, last modified Oct 17 2004]

I'm biased cause the idea's got my
name in the subtitle, but how
exactly would the electromagnets
make this work? The only way I
can immediately see this 'cursive'
in plasma would be to have
something that rarefies the noble
gas inside the tube in that specific
shape [possibly by heating?] thus
lowering the ionization potential
along that route. |
