Abstract:
A method for driving a plasma display panel having discharge cells each corresponding to one pixel formed at each of intersecting points between a plurality of row electrodes arranged at respective scanning lines and a plurality of column electrodes intersecting said row electrodes, comprising the steps of:executing, in each of a plurality of sub-fields forming a display period of one field of an input video signal, a pixel data writing step and a light emission sustaining step, said pixel data writing step being to set each of said discharge cells to one of a light emitting cell and a non-light emitting cell in accordance with a pixel data based on said input video signal, said light emission sustaining step being to allow only said light emitting cells to perform a light emission by a number of times corresponding to a weight of said sub-field, in which at least one of an execution time of said pixel data writing step in each of said sub-fields, an execution time of said light emission sustaining step in each of said sub-fields, and the number of sub-fields within said display period of one field is adjusted in accordance with a jitter of a vertical sync signal in said input video signal.
