ABSTRACT:
In driving an AC type PDP of a matrix formation formed of lines and rows, the PDP includes: plural first and second sustain electrodes arranged on a first substrate, each extending along the line direction, the first & second sustain electrodes being in parallel and adjacent to each other; plural address electrodes arranged on a second substrate opposing the first substrate via a discharge space, each extending along the row direction; and a dielectric layer for covering the first and second sustain electrodes, wherein the method comprises: in causing a writing discharge between the first & second sustain electrodes, the step of: causing supplementally a discharge between the address electrode and the second sustain electrode, wherein the address electrode is positive with respect to the second sustain electrode; and concurrently causing said writing discharge between the first and second electrodes, wherein the first sustain electrode is positive with respect to the second sustain electrode. The second sustain electrode is preferably negative with respect to the reference voltage so that the supplied pulse voltages can be lowered.
