Abstract
A method for driving an AC plasma display panel which makes it possible to reduce flicker in display and have stable and high luminance. In a first step, a wall charge of same amount is produced both in an X electrodeand a Y electrodeby writing discharge during a scanning period. At this time, the amount of the wall charge is adjusted depending on gray scale to be displayed. In a second step, during a sustaining period, a timing of a start of the sustaining discharge is changed by changing a sustaining start control voltage as a voltage of a data electrode. Gradation sequence are displayed through the above steps.
