Abstract:
1. A plasma display panel driving method for driving a plasma display panel, in which discharge cells bearing pixels are formed at intersection points of a plurality of row electrodes corresponding to display lines and a plurality of column electrodes arranged so as to intersect said row electrodes, in a plurality of subfields constituting each field of a video signal, said method comprising: an address step for setting each said discharge cell in accordance with the pixel data of each pixel based on said video signal either in an emission enable state or an emission disable state, for each said subfield; and an emission sustain step for causing only said discharge cells in said emission enable state to emit light repeatedly, wherein said address step comprises a step for, when said discharge cells are in said emission disable state, shifting said discharge cells to an emission enable state by selectively causing said discharge cells to perform a selective writing discharge in accordance with said pixel data, thus generating wall charges in said discharge cells; and, on the other hand, when said discharge cells are in said emission enable state, shifting said discharge cells to an emission disable state by selectively causing said discharge cells to perform a selective erasing discharge in accordance with said pixel data, thus erasing the wall charges in said discharge cells.
