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, in response to a video signal, at each of successively appearing sub-fields forming each of the fields of said video signal, which comprises:in each of said sub-fields, executinga pixel data writing step of sequentially applying a scanning pulse to cause a selective discharge to set said discharge cell to one of a light emitting cell and a non-light emitting cell in accordance with pixel data to each of said row electrodes; anda light emission sustaining step of applying a sustaining pulse to cause a sustaining discharge in only the light emitting cell to each of said row electrodes by only a number of times corresponding to a weight of said sub-field, in whicheither one of said scanning pulses and said sustaining pulses changes in its repetitive period between at least two of said sub-fields.
