Abstract:
1. A method for driving a plasma display panel which displays a frame by replacing the frame with a plurality of sub-fields assigned weights of luminance and applying a sustain pulse to a display electrode X and a display electrode Y alternately, each sub-field having at least an address period during which a cell to be illuminated in selected and a sustain period during which the selected cell is illuminated by the application of the sustain pulse, the method comprising: applying plural kinds of sustain pulses different in light emission luminance to the display electrode X and the display electrode Y during the sustain period of each sub-field; and differentiating a constituent ratio of the plural kinds of sustain pulses in accordance with a gradation level of a frame of a display image, the constituent ratio corresponding to a proportion of each kind of sustain pulse applied during the sustain period.
