Abstract:
A method for driving a plasma display panel, in which a plurality of discharge cells constituting display pixels are arrange in a matrix form, in accordance with an image signal, said method comprising:a simultaneous resetting step for applying reset pulses having gradual level changes at front edge portions thereof to said discharge cells respectively, to cause a reset discharge for initializing said respective discharge cells to either of a light emitting cell state and a non light emitting cell state respectively; a pixel data writing step for applying a scan pulse for causing selective discharge to said discharge cells for shifting said discharge cells selectively to the no light emitting cell state or the light emitting cell state in accordance with pixel data corresponding to said image signal; and a light emission sustaining step for respectively applying, to said discharge cells, sustaining pulses for causing a sustaining discharge that causes only discharge cells brought into the light emitting cell state to emit light repeatedly; wherein said simultaneous resetting step includes a reset pulse waveform adjusting step of adjusting a time period before a level at the front edge portion of said reset pulse reaches a predetermined level in accordance with an average brightness level of said image signal.
