    Patent number: 4019086
    Abstract: The indicia display device of the present invention comprises a sealed compartment having a dielectric substrate therein with anodes and cathode segments imprinted therein. The anodes are imprinted on the dielectric substrate and a layer of dielectric material is imprinted over the anodes. The cathode segments are then imprinted over the layer of dielectric material. An ionizable gas is within the compartment, and produces a cathode glow adjacent the cathode segments whenever an electric potential of a predetermined magnitude is imposed between the cathodes and anodes.
