Gaseous discharge display device

Abstract

Abstract A high resolution gaseous discharge display and/or memory device (21) 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 (23A-23N and 25A-25N) defining the cell walls which, when appropriately energized, produce a confined gaseous discharge in the selected sites. The conductors (23A-23N and 25A-25N) are insulated from direct contact with the gas by a dielectric insulator (33,35,39,41) the dielectric insulator (39,41) 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 display panel. Other embodiments of the dielectric insulator utilize additional small concentrations of elements of Groups VIII or VIB with the above concentration.
