IMPROVED DIELECTRIC INSULATOR FOR GASEOUS DISCHARGE DEVICE Abstract of the Disclosure 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 which, when appropriately energized, pro- duce a confined gaseous discharge in the selected cell. The conductors are insulated from direct contact with the gas by a dielectric insulator, and the dielectric insulator may be composed of or include a layer of refractory material having high secondary emission characteristics such as an alkaline earth metal oxide to prevent degradation of the dielectric layer during operation, to reduce the required discharge voltage and to extend the life of the gaseous discharge panel. Cross Reference to Related Applications Canadian Application Serial No. 162,719 for "Improved Method and Apparatus for a Gas Display Panel" filed by Tony N. Criscimagna et al, December 15, 1969. Background of the Invention Plasma or gaseous discharge display and/or storage apparatus has certain characteristics such as a flat display surface and an inherent capability which render it particularly desirable for alphanumeric display apparatus. One example of a known gaseous discharge device is disclosed in U.S. Patent 3,559,190, "Gaseous Display and Memory -1-
