Abstract: A circuit for driving a gas-discharge device wherein discharge cells (120) each have a column electrode (28) and a segment electrode (26), includes a transformer (80) whose secondary winding (86) provides operating voltages for application to the electrodes. In operation, the secondary winding (86) is arranged during first time intervals to supply to the column electrodes (28) a first potential while a reference potential is applied to the segment electrodes (26). During second time intervals, the secondary winding (86) is arranged to supply to selected segment electrodes (26) a second potential, the reference potential being applied to selected column electrodes (28). Cells including selected column and segment electrodes are repeatedly ignited. A voltage regulator circuit (196) is coupled to the secondary winding (86).
