Abstract: IMPROVED DIELECTRIC OVERCOAT FOR GAS DISCHARGE PANEL A high resolution gaseous discharge display and/or memory device comprises a panel array of bistable charge storage areas designated gaseous discharge cells or sites, each cell having an associated pair of coordinate orthogonal conductors defining the cell walls which, when appropriately energized, produce a confined gaseous discharge in the selected sites. The conductors are insulated from direct contact with the gas by a dielectric insulator, the dielectric insulator being composed of a layer of refractory material having high secondary emission characteristics such as a Group IIA oxide doped with a Group IA element to prevent degradation of the dielectric during operation, to increase the static margin of the panel and improve the stability of the maximum and minimum sustain voltages, thereby providing stable operating voltages and extending the life of the gaseous discharge panel. Other embodiments of the dielectric insulator utilize additional small concentrations of elements of Groups VIII or VIB with the above combination.

Abstract: IMPROVED GAS PANEL ASSEMBLY A method is disclosed for the fabrication of a gas panel assembly with improved static and dynamic operating margins which includes depositing arrays of parallel lines as electrical conductors on a pair of glass plates, providing a dielectric layer over the parallel lines, baking out the respective glass plates in vacuum to eliminate residual gasses or impurities, depositing a layer of refractory electron emissive material over the dielectric of the glass plate assemblies at a prescribed elevated temperature range, and spacing the glass plates a specified distance apart with their arrays substantially orthogonal. The assembly is subsequently fired in an oven to seal the glass plates about their periphery while providing a chamber therebetween, evacuating the chamber, filling it with an illuminable gas, exposing the parallel lines at one end of each glass plate for electrical contact and testing the electrical characteristics of the panel after fabrication.
