Disclosed is a method of driving an AC plasma display panel, wherein charge control is easy, a reset voltage can be lowered, a high contrast and a high brightness can be obtained by using a positive electric power source only, and false contour can be decreased. The method is characterized in that: a voltage (pulse wave) abruptly increased to a voltage for starting a discharge (Vf) is applied to the scan electrodes in the reset period of a first subfield of each frame; the voltage is maintained at the discharge starting voltage (Vf) for a discharge stabilizing time after the discharge starts for which wall charges are sufficiently accumulated on a dielectric layer covering the scan electrodes, the sustain electrodes and the data electrodes; subsequently, the voltage is slowly decreased to OV; and a voltage of OV is applied to the sustain electrodes while the discharge starting voltage (Vf) is applied to the scan electrodes, and then the voltage is slowly increased to about a sustain voltage (Vs) while the voltage to be applied to the sustain electrodes is slowly decreased form the discharge starting voltage (Vf). |
