Plasma display panel driving method

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 of the display cells, 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, and a microemission step, in which the display cells in the state of the ON mode are caused to microemission discharge, said reset step, said address step and said microemission step being executed in a first subfield when a display period of a single field in the video signal is divided into a plurality of subfields, wherein
• in the reset step, the reset discharge is generated between ones of the row electrodes of the row electrode pairs and the column electrodes by applying a voltage, using the ones of the row electrodes as the anode and the column electrodes as the cathode, between the one of the row electrodes and the column electrodes, and
• in the microemission step, together with generating the microemission discharge between the column electrodes and the ones of the row electrodes in 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, a potential of the same polarity as a potential applied to the ones of the row electrodes is applied to the others of the row electrodes of the row electrode pairs.
