Abstract:
1. A method for driving a plasma display panel, in which a first substrate and a second substrate are arranged in opposition with a discharge space having a discharge gas sealed therein positioned between the first substrate and the second substrate, and in which display cells are formed at each intersection of a plurality of row electrode pairs formed on the first substrate and a plurality of column electrodes formed on the second substrate, the plasma display panel being driven corresponding to pixel data of each pixel based on a video signal, the method comprising: sequentially executing a reset step, in which the display cells are initialized to a state of an OFF mode by generating a reset discharge between ones of the row electrodes of the row electrode pairs and the column electrodes within the display cells by applying a voltage, using ones of the row electrodes of the row electrode pairs as the anode and the column electrodes as the cathode, between the ones of the row electrodes and the column electrodes, and an address step, in which the display cells are changed to a state of an ON mode by causing the display cells to selectively address discharge, corresponding to the pixel data, said reset step and said address step being executed in at least a first subfield and a second subfield immediately following the first subfield when a display period of a single field in the video signal is divided into a plurality of subfields; executing a sustain step that causes a sustain discharge in only the display cells in the state of the ON mode by alternately applying a sustain pulse to the ones of the row electrode pairs and the others of the row electrode pairs in each subfield subsequent to the second subfield; and executing a microemission step, in which a microemission discharge is generated between the ones of the row electrodes and the column electrodes within the display cells in the state of the ON mode by applying a voltage, using the ones of the row electrodes as the anode and the column electrodes as the cathode, between the ones of the row electrodes and the column electrodes while respectively applying a potential lower than the voltage generated between the ones of the row electrodes and the others of the row electrodes to the ones of the row electrodes and the others of the row electrodes when applying the sustain pulse immediately after the address step in the first subfield.
