ABSTRACT:
Improved writing and erasing in AC gas discharge display panels is obtained by applying a special normalizing voltage waveform to cause the cells to be in a more standardized state, so that the applied writing and erasing pulses act to cause wall voltage changes which are less sensitive to the cell's recent history. The special normalizing waveform is applied adjacent to the erase pulse and/or to the write pulse and acts to fire the cells in a manner such that there is no loss in the memory state of the cells.
