Abstract: In a method for driving a plasma display panel, scanning electrodes (SC1-SCn) of the plasma display panel are classified into two scanning electrode groups, and a subfield write period is divided into two write periods that correspond to the two scanning electrode groups. In at least one write period, scanning pulses, which transit from a second voltage (Vs2) higher than a scanning pulse voltage (Vad) to the scanning pulse voltage (Vad) and transit again to the second voltage (Vs2), are applied in sequence to the scanning electrodes (SC1, SC3 and so on) belonging to one scanning electrode group. A third voltage (Vs3) higher than the scanning pulse voltage (Vad) or a fourth voltage (Vs4) higher than the second voltage (Vs2) and the third voltage (Vs3) is applied to the scanning electrodes (SC2, SC4 and so on) belonging to the other scanning electrode group. While the scanning pulse voltage (Vad) is applied to at least adjacent scanning electrodes (SC1, SC3 and so on), the third voltage (Vs3) is applied. ® KIPO & WIPO 2009
