Abstract:
A method for driving a plasma display panel comprising a plurality of sustain electrodes and a plurality of scan electrodes disposed in parallel with each other on a substrate for each display line; a plurality of addressing electrodes isolated electrically from said sustain electrodes and said scan electrodes and disposed so as to cross said sustain electrodes and said scan electrodes; and discharge cells formed in areas in which said addressing electrodes cross said sustain electrodes and said scan electrodes;said method including: odd-numbered fields for carrying out display between odd-numbered sustain electrodes and odd-numbered scan electrodes and between even-numbered sustain electrodes and even-numbered scan electrodes; even-numbered fields for carrying out display between said odd-numbered sustain electrodes and said even-numbered scan electrodes and between said even-numbered sustain electrodes and said odd-numbered scan electrodes; each of said odd-numbered and even-numbered fields including: a reset period for applying a predetermined voltage to said sustain electrode, said scan electrode and said addressing electrode and executing a reset discharge in a plurality of said discharge cells in order to make uniform a charge distribution among a plurality of said discharge cells; an addressing period for executing a write discharge between said scan electrode and said addressing electrode in a selected one of said discharge cells and executing a selective write operation in accordance with display data; and a sustain discharge period for applying alternately a sustain discharge pulse to said sustain electrode and said scan electrode in order to repeatedly execute discharge light emission for displaying the display data in said discharge cell in which the selective write operation is executed in said addressing period; wherein a reset discharge pulse having a voltage higher than a discharge start voltage necessary for starting said reset discharge is applied in said reset period to said sustain electrode and said scan electrode for the period in which the discharge is started in only said discharge cell that has executed said sustain discharge and said discharge cells adjacent to the former discharge cell, and then a potential difference between said sustain electrode and said scan electrode is made substantially zero so that an erase discharge is done for at least said cell that has executed said sustain discharge.
