A luminous discharge display device having two distinct, independent discharge
chambers, stacked vertically; of substantially flat circular shape containing inert
gas mixtures, and a central electrode coupled to a power supply which provides
ionizing means for the gas. The device utilizes two grooves formed into defining
members of the discharge chambers to increase the capacitance along their length
due to the inverse relationship between dielectric width and capacitance. Two electrode
assemblies are biased out of phase with respect to the main electrode further increasing
the capacitance and converging the luminous discharge at that specific point and
are fitted into the circular grooves. A clock mechanism moves the electrode assemblies
along their respective grooves thus creating a controlled motion of the luminous
glowing plasma.
