Abstract:
1. A method for driving a plasma display panel consisting of plural display electrodes forming pairs of electrodes for a sustain discharge, plural address electrodes arranged so as to intersect the pairs of electrodes, and display cells formed at the intersections of the pairs of electrodes and the address electrodes, comprising: an initialization period during which the display cells are initialized; an address period during which an address discharge is caused to occur according to display data of each display cell so that each display cell is put into a state in accordance with the display data; a charge form period during which a charge form pulse is applied to the pair of electrodes; and a sustain discharge period during which a sustain pulse and that with the opposite polarity are applied alternately to the pair of electrode so as to cause a sustain discharge light emission to occur, wherein the initialization period comprises a write period during which first amount of charges is accumulated in the display cells and a charge adjust period during which the first amount of charges accumulated during the write period is adjusted to second amount of charges, wherein the voltage to be applied to the pair of electrode during the charge adjust period is an inclined wave-shaped charge adjust pulse, the voltage of which varies gradually, and wherein the absolute value of voltage of the charge form pulse is greater than the absolute value of voltage of the sustain discharge pulse.
