Abstract
Abstract There is disclosed a gas discharge display/member panel comprising opposed dielectric charge storage members backed by conductor electrode members and having an ionizable gas confined within the space between the opposed dielectric members, the conductor members being specific standardized visual shapes so as to form upon gas discharge alpha-numeric and other selected forms and shapes.

A gas discharge display panel system for displaying characters comprised of numerals, letters and words comprising in combination, a first rigid inorganic nonconductive support member, a first plurality of continuous conductor members formed in situ and spaced apart relation on an inner surface of said first rigid nonconductive support member, said first plurality of conductor members being specific standardized visual shapes arranged on said first nonconductive support member and a pattern such that selective activation thereof constitutes numerals, letters and words, a layer consisting essentially of a heat resistant inorganic dielectric material formed in situ on at least all surfaces of said first plurality of conductor members except the ends thereof and on the surface of said first support member surface therebetween, a second rigid inorganic nonconductive support member having an inner surface area facing the inner surface area of said first rigid nonconductive support member, a plurality of second continuous conductor members formed in situ on said inner surface of said second rigid nonconducting support member and in opposed cooperating relationship with respect to the conductors on said first nonconductive support member to define therewith a plurality of gaseous discharge points, a second layer of heat resistant inorganic dielectric material formed in situ on at least all surfaces of said second plurality of conductor members except the ends thereof and on the surface of said second support member therebetween, an inorganic spacer sealant means joining said first and said second support members in spaced apart relation define with said inner surface areas of said support members thin hermetically sealed gas chamber means, an ionizable gaseous medium within said thin gas chamber, and means for applying exciting potentials to selected ones of the conductors on said first and said second inorganic nonconductive support members to generate selected numerals, letters and words according to the shapes of the selected conductors.
