ABSTRACT:
Multicelled gas discharge display/memory device addressing is enhanced by altering the sustainer voltage waveform during addressing to provide longer intervals for the transfer of addressed cells between an "on state" and an "off state" of discharge. Sustainer waveforms allow more time for "turn on" and "turn off" partial select signals to be effective by extending the sustainer waveform pedestals on which the partial selects are imposed. These sustainer alterations can be performed by extending the sustainer periods in which addressing is performed or by maintaining the sustainer periods and shortening those portions of the period which are not utilized for addressing as by employing only a "write" pedestal or only an "erase" pedestal.
