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.
Abstract:
There is disclosed a multiple gas discharge display panel comprising a matrix of display cells formed by intersecting electrodes and having one or more pilot cells in the onstate for the conditioning of the matrix display cells, each pilot cell being located in the matrix border and being defined by the intersection of one electrode common to matrix display cells and another electrode not common to matrix display cells, the geometric width of the common electrode being greater in the matrix border pilot cell than in the matrix display cells.
Abstract:
There is disclosed a gas discharge device gas mixture consisting essentially of about 0.1 to 5 percent atoms of xenon and about 99.9 to 95 percent atoms of a helium-based composition, the mixture having a pressure of 100 to 700 Torr, this mixture to be used in a color phosphor gas discharge display/memory device so as to provide adequate stimulation of phosphors in a gas discharge display panel with low operating voltages and without a pronounced visible discharge emission to distort phosphor colors.
Abstract:
There is disclosed a gas discharge display/memory device containing electrode arrays and an ionizable gaseous medium, the gaseous medium having incorporated therein an effective amount of helium sufficient to decrease the minimum applied voltage sufficient to sustain a gas discharge once initiated and increase the memory margin of the device. In the preferred embodiment, there is incorporated at least about 0.01 percent atoms of helium, based on the gaseous medium concentration after helium addition, to an initial gaseous medium consisting essentially of about 99.5 percent to about 99.99 percent atoms of neon and about 0.5 percent to about 0.01 percent atoms of at least one member selected from argon, xenon, and krypton. The gas discharge device is preferably of a display/memory type wherein electrical charges are stored on opposing dielectric surfaces.
