The present invention relates to a plasma display panel, and more particularly to a method and apparatus for decreasing an afterimage of a plasma display panel. According to an embodiment of the present invention, a method for decreasing an afterimage of a plasma display panel by using an average picture level, comprises the steps of: generating an average picture level-to-sustain pulse number curve having a trigonometric function period or a linear function period; and driving the plasma display panel by calculating an average picture level of an input image, and deriving the number of sustain pulses corresponding to the calculated average picture level from the average picture level-to-the number of sustain pulses curve. The method and appratus for decreasing an afterimage of a PDP by using an APL according to the present invention can minimize the afterimage by using an APL-Nsus curve having a trigonometric function period or a linear function period and preventing an abrupt change in the number of sustain pulses when the APL varies. |
