Abstract:
A method of driving a plasma display panel having a discharge cell corresponding to one pixel at each intersection of each of a plurality of row electrodes arranged to form each scanning line with each of a plurality of column electrodes intersecting with said row electrodes, said method comprising the steps of:dividing a display period of one field into a plurality of subfields; executing a resetting stage, which simultaneously initializes all said discharge cells, wherein said resetting stage is executed only in the first subfield of said one field; after said resetting stage, setting said discharge cells to either light emitting cells or non-light emitting cells in accordance with display pixel data only in a pixel data writing stage in one or less of said subfields in said one field; wherein said subfields comprise N consecutive subfields in said one field, wherein N consecutive subfields define N+1 levels of gradation, wherein an (N+1)th gradation level is displayed in said light emitting cells by continuously sustaining light emission in said light emission sustaining stage, without interruption, in each of n consecutive subfields of said N consecutive subfields, wherein 0&lE;m&lE;N, and wherein said pixel data writing stage for the discharge cell is provided only once or less in said one field without regard to the level of gradation.
