Abstract
A driving circuit for a gaseous discharge display device comprises a processing circuit for processing data signals and clock signals and a data input counter connected in parallel and a scanning control circuit connected to the data input counter to control the turning on and off of scan operations so that unnecessary power consumption can be reduced and the contrast ratio enhanced by preventing auxiliary discharge effects from occurring when no data is input for display at the gaseous discharge display device.
