Abstract
Large values of avalanche current are avoided in a gas discharge display panel by 'staggering' in time the application of the sustain voltage waveforms to different portions of the display panel. A plurality of individual sustain circuit modules each having two 100 v FET's are connected to a common sustain circuit module having another two 100 v FET's. The 'staggered' sustain operation is provided by selectively controlling the individual sustain circuit modules. The individual and common sustain circuit modules combine to alternatively produce 0-200 v square wave or a 0-100-200 v return-to-midpoint waveform by selectively controlling the FET's.
