ABSTRACT:
A glass cylindrical or spherical double walled enclosure defines a containing envelope for containing an ionized gas discharge among dielectric pellets or beads. The double walls of the enclosure form a torus or hollow cylinder, sphere or other suitable shape and define an enclosed glass discharge area. The gas discharge area is formed by the double walls being filled with an ionizable gas. Electrodes are attached to ends of the enclosure and a constant current transformer is connected for supplying a high voltage sufficient to produce visible discharges in the gas discharge area. The center of the torus, or other suitable shape, is accessible to the outside and allows the application of an electrostatic grounding conductor of metal, or a conventional neon tube which acts as a double duty attracter and illuminator for the background of the display device. Traps are provided between the dielectric pellets and the electrodes to prevent the dielectric pellets from contacting the electrodes.
