Abstract
For the decoupling between drive lines 9 for applying the firing and extinguishing pulses and supply lines 7 for supplying the sustain voltage, as well as for firing and maintaining discharges in gas discharge display devices, electrodes 2 are applied via conductive multi-layer zones 3 of the surrounding dielectric layer 4, from the supply lines 7 and also via counter-plates provided on the surface of the dielectric layer 4. The counter-plates are interconnected by lines 9, and form with associated counter-electrodes, respective capacitors in which one counter-plate vertical row can represent a first coordinate while the second coordinate may be formed by time-defined shifting of this vertical row of counter-plates in a direction which is vertical with respect to its extension. If instead of a linear displacement of the counter-plate row, there is an angular displacement round a fixed center of rotation, a planar coordinate image display representation may be formed which is advantageous in cases of displays covered by rotating scanning elements such as, for example, radar systems.
