Abstract
Abstract 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 in contact with the gaseous medium, each dielectric being backed on the non-gas contacting side by an array of conductor (electrode) members, the conductor members behind each dielectric material member being appropriately oriented with respect to the conductor members behind the opposing dielectric material member so as to define a plurality of discrete discharge volumes constituting a discharge unit, the gas contacting surface of the dielectric material having a first layer of at least one oxide of Al, Ti, Zr, Hf, and Si and a second layer of lead oxide, both layers being applied to the surface in an amount sufficient to provide substantially lower and more stable panel operating voltages which do not significantly change with panel operating time.

Claim 4
Dependent Claim
29 words
The discharge panel as defined in claim 1 wherein each oxide layer thickness is in a range of from about 200 angstom units up to about 10,000 angstrom units.
Claim 5
Dependent Claim
155 words
In a gaseous discharge panel comprising a chamber formed by a pair of opposed walls and being sealed to contain an ionizable gaseous medium therein, said opposed walls including dielectric material charge storage surfaces on the gaseous side of each wall and being backed by electrode members, the electrode members behind one of the dielectric material surfaces being transversely oriented with respect to the electrode members behind the other opposing dielectric material surface so as to define a plurality of discharge units, the improvement comprising: a. a first contiguous layer of at least one oxide of Al, Ti, Zr, Hf, or Si, disposed on each dieleCtric surface, b. A second contiguous layer of lead oxide disposed on said first layer, and c. each said layer having a thickness of an amount sufficient to decrease the operating voltages of the panel and to provide stable panel operating voltages for a given period of panel operating time.
