ABSTRACT:
A circuit for driving one electrode group of a gas discharge display panel includes a plurality of PNP transistors and NPN transistors. The emitter electrodes of the PNP transistors are connected to a positive voltage source and the emitter electrodes of the NPN transistors are connected to ground. Diode means are connected between the collector electrodes of the PNP transistors and those of the NPN transistors across matrix points formed at the intersections of a first plurality of conductors connected respectively to the collector electrodes of the PNP transistors and a second plurality of conductors connected respectively to the collector electrodes of the NPN transistors. The individual electrodes of one electrode group of the gas discharge panel are connected to the diode means. The circuit also includes a first plurality of diodes and a second plurality of diodes connected to the first plurality of conductors and the second plurality of conductors, respectively.
