Method of manufacturing a multiple gaseous discharge display/memory panel having improved voltage characteristics

Claim 1

In the manufacture of a multiple gas discharge display/memory device comprising an ionizable gaseous medium in a gas chamber formed by a pair of opposed dielectric material members, each backed by an array of electrode members, each said dielectric material and array of electrode members being backed by a glass substrate, the electrode members behind each dielectric material member being transversely oriented with respect to the electrode members behind the opposing dielectric material so as to define a plurality of discharge units, the surfaces of said dielectric material members serving to store charges during each half-cycle of operation, the improvement comprising selectively enriching an uncured dielectric material with about 0.5 to about 8 weight percent, based on the total weight of the dielectric material, of at least one element in the oxide state and selected from the group consisting of lithium, sodium, potassium, rubidium, cessium, francium, beryllium, magnesium, calcium, strontium and barium to provide gas discharge device operating voltages which are substantially uniform and which do not significantly change with time after a period of aging, applying said selectively enriched dielectric material to at least one of said glass substrates supporting an array of electrodes, and heat curing said selectively enriched dielectric material to form said dielectric material member.
