Zusammenfassung:A flat type multi-figure numeric or alpha numeric display device employing a cold cathode gas discharge with a barrier anode associated with each figure. Each figure of the device is composed of segmented electrodes located in a co-planar arrangement. Segments are selectively energized by the driver logic to display required figures, in combination with an electrode in the same plane which selectively may function as either an anode or as an ion barrier.
