Abstract:
1. A method for driving a plasma display panel displaying a frame composed of a plurality of subfields, comprising: applying first and second sustain pulses having at least two kinds of waveforms different in luminance, the second sustain pulse having a higher luminance than the first sustain pulse, and the first and second sustain pulses being applied according to a weight of luminance to be given to the sub-fields at a predetermined constituent ratio in a sustain period of at least one sub-field; and adjusting the constituent ratio of the first and second sustain pulses according to a maximum luminance of the frame to be displayed wherein, if the maximum luminance of the frame to be displayed is lower than a luminance of a maximum gradation corresponding to the number of sub-fields, a constituent ratio of the first sustain pulse is increased such that the luminance of the maximum gradation decreases.
