Abstract
A voltage of sustain electrodes is lowered from Ve1 to a ground potential at a time point immediately before a first SF (sub-field). Then, a pulsed positive voltage is applied to data electrodes at a starting time point of a setup period of the first SF. Immediately before this, a large amount of negative wall charges is stored on the sustain electrodes and positive wall charges are stored on the data electrodes, and therefore application of the pulsed positive voltage to the data electrodes generates strong discharges between the sustain electrodes and the data electrodes. After that, application of a ramp voltage to scan electrodes is started at a time point, generating setup discharges between the scan electrodes and the sustain electrodes.
