Abstract
An improved AC plasma display panel structure and method of driving for improved efficiency. Gaseous discharges can tunnel or initiate in microchannels parallel to sustain electrodes in a front substrate lowering operating voltages and allowing the use of more efficient gas mixtures. A write step applies a pulse to selected first and second sustain electrodes corresponding to cells on a row that will be turned ON, and an erase step applies a voltage to first and third electrodes corresponding to cells that are to be turned OFF. Write discharges are tunneled through microchannels.
