Gas discharge display panel with lanthanide or actinide family oxide

摘要

A gas discharge device containing at least two electrodes is shown, at least one of the electrodes being insulated from the gas by at least one dielectric insulating member containing a predetermined beneficial amount of an oxide of at least one lanthanide series rare earth metal or at least one actinide series rare earth metal. In one embodiment, a multiple gaseous discharge display/memory panel having an electrical memory and capable of producing a visual display is used, the panel having an ionizable gaseous medium in a gas chamber, formed by a pair of opposed dielectric material charge storage members, each of which is respectively backed by an array of electrodes, the electrodes behind each dielectric member being oriented with respect to the electrodes behind the opposing member so as to define a plurality of discrete discharge volumes constituting a discharge unit. Each opposing dielectric surface is coated with a metal oxide of the lanthanide rare earth series or the actinide rare earth series.
