Abstract: A driving circuit for a gas-discharge display device (20) includes a pair of switching members (94, 144) and the secondary windings (92) of a transformer (118) wired in series with one of the switching members. The switching members in response to receiving out-of-phase control signals alternately apply a low voltage pulse to the display device. The secondary windings of the transformer output continuously a high voltage pulse in phase with one of the switching members. Upon the generation of appropriate control signals enabling the operation of the switching members, a voltage of sufficient magnitude is applied to selected cell segments in the display device to fire the cells. The transformer together with the low voltage pulses are driven by a high frequency clock to provide a high intensity display operation.
