Abstract:
1. A method for driving a plasma display panel in accordance with pixel data based on a video signal, in which plasma display panel is constructed in such a manner that a first substrate and a second substrate are arranged so as to face each other through a discharge space in which a discharge gas has been sealed, a discharge cell is formed in each of cross portions of a plurality of row electrode pairs formed on said first substrate, each of said row electrode pairs is composed of a first row electrode and a second row electrode, and a plurality of column electrodes formed on said second substrate, and said panel has a phosphor layer containing a phosphor material formed on a surface of each of said discharge cells which are in contact with said discharge space and the driving method comprises: executing an addressing step of applying a scanning pulse to each of the first row electrodes and a sustaining step in each of a plurality of subfields every unit display period which is one frame display period or one field display period in said video signal and executing a resetting step of applying a reset pulse to each of said first row electrodes in one of said subfields prior to said addressing step; in said resetting step of said one of said subfields in a first one of said unit display periods, applying the reset pulse having a first peak electric potential to one of said first row electrodes and applying the reset pulse having a second peak electric potential lower than said first peak electric potential to remaining ones of said first row electrodes; and in said resetting step of said one of said subfields in a second unit display period subsequent to said first unit display period, applying the reset pulse having a third peak electric potential lower than said first peak electric potential to all of said first row electrodes.
