A method of driving a plasma display panel is disclosed. According to this method, a global writing pulse is applied between the sustaining electrode X and the scan electrode Yi at a first time point of the reset period, so that wall charges of every cells in the plasma display panel are produced by the discharge between the sustaining electrode X and the scan electrode Yi. The global writing pulse includes a waveform having a large slope, which rises from the first voltage to the second voltage, and a waveform having a relatively small slope, which rises from the second voltage to the third voltage. Raising the voltage in a large slope can make the cells accumulate a large amount of wall charges, and raising the voltage in a small slope can avoid affecting the image quality by producing a high brightness.
