CIRCUIT FOR SUPPLYING SPECIFIED ONE OF EXTERNAL ELECTRODES OF A GAS DISCHARGE DISPLAY PANEL WITH IRECTIONAL FIRING VOLTAGE PULSES AND OTHERS WITH PULSES OF A REDUCED VOLTAGE

摘要

In a driving circuit for a gas discharge display panel having first and second electrodes externally disposed on opposite sides of gas discharge cells, use has been made of an arrangement for supplying pulses of a unidirectional firing voltage of the panel to specified of the first electrodes. The present arrangement comprises means for producing the unidirectional pulses and means for supplying unidirectional pulses, with a reduced pulse height, to others of the first electrodes.
