ABSTRACT:
A one sided a.c. plasma panel comprises a glass substrate encapsulated within a pair of glass plates dividing the panel into two interconnected chambers. One set of conductor arrays originate within the rear aperture are are conducted through display vias to circular electrodes in the front aperture. The second set of electrodes comprise annular rings which are concentric and coplanar with the circular electrodes. This configuration limits discharge spread on the display surface, permitting increased resolution without crosstalk. Multicolor capability is provided by the combination of ultraviolet sensitive phosphors on the inner surface of the front faceplate and an ultraviolet emitting gas within the plasma panel.
