Abstract
Abstract There is disclosed a display/memory panel or unit containing an ionizable gaseous medium and at least one dielectric charge storage member, the gaseous medium consisting essentially of neon and about 0.01 to about 10 percent atoms of xenon so as to significantly increase the memory margin of the panel. In one preferred embodiment the gaseous medium consists essentially of neon and about 0.05 to about 5 percent atoms of xenon, most preferably about 0.05 to about 0.5 percent atoms of xenon. The gaseous medium may contain small beneficial amounts of other gaseous ingredients, such as mercury. Likewise, buffering quantities of helium may be incorporated into the panel with the ionizable medium. In the most preferred practice hereof, the charge storage portion of the dielectric is coated with at least one layer of at least one member selected from oxides of lead, aluminum, titanium, zirconium, hafnium, silicon and Group IIa.
