ABSTRACT:
An improved write circuit for a gas panel produces a sequence of alternating polarity write pulses that are superimposed on a sequence of half cycle pulses of the sustain waveform. Thus the accumulation of charges on the walls of a light-emmitting cell that is required for a write operation is produced by a sequence of write pulses, and each write pulse is lower in amplitude than is required for a single write pulse. The write pulses are progressively shifted ahead in phase to further improve the operation.
