Abstract:
1. A method for driving a plasma display panel, comprising the steps of: supplying a first re-set waveform to a scanning electrode during a reset interval of the n-th (n is a natural number) sub-field; supplying a first scan pulse to the scanning electrode during an address interval of the n-th sub-field; supplying a first sustain pulse to the scanning electrode during a sustaining interval of the n-th sub-field; supplying a second re-set waveform to the scanning electrode during a reset interval of a (n+1)-th sub-field; supplying a second scan pulse to the scanning electrode during an address interval of the (n+1)-th sub-field; supplying a second sustain pulse to the scanning electrode during a sustaining interval of the (n+1)-th sub-field, wherein a peak voltage value of the second re-set waveform is less than a peak voltage value of the first re-set waveform and greater than a peak voltage value of the second sustain pulse, wherein the first re-set waveform comprises a first ramp-up waveform and a first ramp-down waveform, and wherein the first ramp-down waveform falls to a first negative voltage value and a voltage value of the first scan pulse is greater than the first negative voltage value in an absolute value.
