AC Gas Discharge Display Panel using Woven Wires and Incorporating Color

A gaseous discharge display device structure for producing a mulitcolor display utilizes woven wires of conductive metal coated with dielectric glass as discharge electrodes and phosphors excited by the ultraviolet radiation generated in the glow of a helium neon xenon discharge.

Referring to Fig. 1, woven wires 3 and 4 of conductive metal, such as aluminum, gold or silver, coated with dielectric glass 5, are used as orthogonal sets of discharge electrodes. The woven electrode structure is placed on and fastened to plate glass substrate 1. A coating of refractory high secondary emissive material 6, such as magnesium oxide, is then deposited over the dielectric glass to protect the surface of the glass against degradation from ion bombardment and provide low operating voltages. Green-emitting, red-emitting and blue-emitting phosphors 10, such as Zn(2) SiO(4): Mn, YVO(4): Eu and CaWO(4): Pb, repectively are deposited in dot or strip patterns on plate glass substrate 2. The phosphor patterns are aligned to the woven electrode structure, as shown in Fig. 1, and plate glass substrates 1 and 2 are then sealed about their edges, the panel evacuated, and a gas mixture emitting sufficient ultraviolet radiation, such as helium neon xenon, is introduced into the panel under a less than atmospheric pressure during a backfill operation.
