METHOD FOR DRIVING PLASMA DISPLAY PANEL AND PLASMA DISPLAY DEVICE

摘要

The present invention aims to improve a low gradation expression ability by reducing the brightness of the 1st gradation level to about 1.05 cd/m2 of the intermediate brightness between the 0th gradation level and the 2nd gradation level at the time of driving a PDP. During a sustain erase period (P13) of a subfield (SF1) with the smallest brightness weight among a plurality of subfields (SF), a positive voltage (Vbk) that is smaller than a voltage (Vsus) applied during a sustain period (P23) of other SFs is applied to scan electrodes. Also, during the sustain erase period (P13) of SF1, a positive voltage (Vda) is applied to address electrodes or a positive voltage (Vda) is applied to the address electrodes during at least one period of a voltage rising period (T11) of an all-cell reset period (P11).
