STAGGERED SUSTAIN VOLTAGE GENERATOR AND TECHNIQUE

摘要

STAGGERED SUSTAIN VOLTAGE GENERATOR AND TECHNIQUE 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 100v FET's are connected to a common sustain circuit module having another two 100v 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 0-200v square wave or a 0-100-200v return-to-midpoint waveform by selectively controlling the FET's. Ki9-78004
