Abstract:
A method of driving a plasma display panel comprising a plurality of pairs of first and second electrodes arranged in parallel, and a plurality of third electrodes crossed with a plurality of said first and second electrodes, said first, second and third electrodes selectively defining a plurality of cells adapted for light emission by discharge, said method comprising the steps of:performing self-erasure discharge by applying a reset voltage at least to a part of said first, second and third electrodes and thereby causing a plurality of said cells to discharge, and setting a plurality of said cells in a predetermined state by neutralizing the charge of each of said electrodes;addressing each of said cells in said predetermined state by applying a voltage selectively to said cells in accordance with the display data and accumulating the charge corresponding to said display data for each cell; andapplying a sustaining discharge voltage to a plurality of said cells and thereby causing the cells with predetermined charge accumulated therein to discharge and emit light;wherein said reset voltage is set in such a manner that said self-erasure discharge occurs when said reset voltage is superposed on the charge accumulated on said electrodes of a plurality of said cells, and said self-erasure discharge is caused selectively in a part of said cells.
