There is disclosed a multiple gaseous discharge display/memory panel having an electrical memory and capable of producing a visual display, the panel being characterized by an ionizable gaseous medium in a gas chamber formed by a pair of opposed dielectric material charge storage members which are respectively backed by a series of parallel-like conductor (electrode) members, the conductor members behind each dielectric material member being transversely oriented with respect to the conductor member behind the opposing dielectric material member so as to define a plurality of discrete discharge volumes constituting a discharge unit, the surface of the dielectric material having at least one oxide of Al, Ti, Zr, Hf, and Si applied thereto in an amount sufficient to provide stable panel operating voltages which do not significantly change with panel operating time.
An article of manufacture for a gaseous discharge display/memory device consisting of a dielectric body having at least one electrode on one side thereof and on the opposite side thereof a coating consisting of at least one oxide of Al, Ti, Zr, Hf, or Si in an amount sufficient to provide gaseous discharge operating voltages in the device which do not substantially change over a given period of operating time.
An article of manufacture for a display device utilizing gas discharge and comprising a dielectric material member having a pair of oppositely facing surfaces and comprising heavy metallic elements, at least one electrode on one of said surfaces and, on the opposite surface thereof, a layer of a composition selected from the group consisting of oxides of aluminum, titanium, zirconium, hafnium and silicon for providing operating voltages in the display device which do not significantly vary or substantially change during long term operation of the display device and thereby increase the effective and useful operating life of the display device.
An article of manufacture for a display device utilizing gas discharge and consisting of a dielectric material member having a pair of oppositely facing surfaces and comprising heavy metallic elements, a group of electrodes on one of said surfaces, and a protection layer consisting of at least one oxide of aluminum, titanium, zirconium, hafnium and silicon on the other of said surfaces for providing operating voltages in the display device which do not significantly vary or substantially change during long term operation of the display device and thereby increase the effective and useful operating life of the display device.
