Method of driving a plasma display panel
A plasma display panel (PDP), and a method of driving plasma display panel, achieve improved contrast by minimizing quantity of luminescence in a non-luminescent display period, that is, a reset period. A method of driving a PDP having a plurality of discharge cells with a plurality of scanning electrodes, a plurality of sustain electrodes, and a plurality of address electrodes involves forming a frame having a plurality of sub-fields; causing a reset discharge in only first sub-fields of the respective plurality of discharge cells; deciding ON/OFF state of discharge cells in current sub-field in accordance with ON/OFF state of discharge cells in previous sub-field; and converting the discharge cell into any one of ON/OFF wall electric charges in accordance with the ON/OFF state of the decided discharge cell.
