Abstract
A method for driving an Independent Sustain/Address line (ISA) AC plasma display panel comprises the steps of: energizing address and sustain lines to turn on all four pixel cells in a cell group; applying an erase pulse to an address cell to cause a first coupling cell in the cell group to have wall charges deposited therein; applying next, a preset duration potential between intersecting sustain lines, one sustain line intersecting the first coupling cell and firs and second adjacent pixel cells, to migrate electrons from a discharge of the first coupling cell to a first adjacent pixel cell to erase the pixel cell, such potential further causing an 'on' pixel cell adjacent to the first coupling cell to discharge; applying next, another erase pulse to an address cell, to cause a different coupling cell to have wall charges deposited therein; and applying next, a lesser duration potential than the preset duration potential, between a pair of intersecting sustain lines to migrate the deposited wall charges to a pixel cell adjacent the different coupling cell to erase to pixel cell, such lesser duration potential being insufficient to cause another pixel cell adjacent the different coupling cell to discharge.
