Gas discharge display panel having capacitively coupled, multiplex wiring for display electrodes

A gas discharge display panel, comprising:

• first and second substrates, each thereof defining a display area;
• first and second pluralities of display electrodes respectively formed on said first and second substrates, each said plurality of display electrodes extending in generally parallel relationship across, and in a predetermined direction relative to, said display area portion of the respective said substrate;
• first and second insulating layers disposed on said first and second pluralities of display electrodes;
• said first and second substrates being assembled in generally parallel, spaced relationship to define a discharge gas gap therebetween and with said respective display areas thereof in alignment and said first and second pluralities of display electrodes spatially intersecting in said aligned display areas, said spatial intersections defining discharge cells corresponding to individual display dots of a matrix thereof in said display area;
• a discharge gas received within said discharge gas gap;
• at least one multiplex wiring circuit formed on and associated with a corresponding one of said first and second substrates, each said associated substrate having first and second peripheral portions extending beyond corresponding first and second opposite edges of said display area thereof, in said predetermined direction, and each said multiplex wiring circuit comprising:
• a first plurality of coupling electrodes respectively corresponding to said display electrodes of the associated substrate, a first plurality of driving electrodes of said second predetermined number and respectively corresponding to said plurality of successive display electrodes of each of said successive groups thereof, and an insulating layer intervening between said first pluralities of coupling and driving electrodes, said first pluralities of coupling and driving electrodes and said intervening insulating layer being formed on said first peripheral portion of said associated substrate;
• said first plurality of driving electrodes being arranged in generally parallel relationship, and extending transversely of said predetermined direction;
• said first plurality of coupling electrodes being arranged in a plurality of successive groups of said first predetermined number, corresponding to said successive groups of successive display electrodes, with each said group comprising a plurality of successive coupling electrodes of said second predetermined number, the corresponding said successive coupling electrodes of said successive groups being positioned in alignment with and capacitively coupled through said intervening insulating layer to said respectively corresponding driving electrodes of said first plurality thereof;
• a second plurality of coupling electrodes respectively corresponding to said plurality of display electrodes, a second plurality of driving electrodes of said first predetermined number and respectively corresponding to said successive groups of said display electrodes, and an insulating layer intervening between said second pluralities of coupling and driving electrodes, said second pluralities of coupling and driving electrodes and said insulating layer being formed on said second peripheral portion of said associated substrate;
• said second plurality of driving electrodes being disposed in generally aligned relationship in a direction traversing said predetermined direction and in positions corresponding to the respective said plurality of successive groups of said display electrodes;
• said second plurality of coupling electrodes being disposed in generally aligned relationship in a direction traversing said predetermined direction with the coupling electrodes respectively associated with said successive display electrodes of each successive group thereof disposed in alignment with and capacitively coupled through said intervening insulating layer to the respectively corresponding driving electrode of said second plurality thereof;
• first means individually connecting said display electrodes from said first edge of said display area of said associated substrate to said respectively corresponding first coupling electrodes;
• and
• second means individually connecting said display electrodes from said second edge of said display area of said associated substrate to said respectively corresponding second coupling electrodes.
