Abstract: During a setup interval, the wall charges of scan and sustain electrodes having performed sustain discharging in the previous sub-field are adjusted; a part of the positive charges of the scan electrode that is on the sustain electrode side is reversed to negative charges; and a part of the negative charges of the sustain electrode that is on the scan electrode side is reversed to positive charges. During an address interval, a write pulse is applied to the scan electrode, and a priming discharge between the scan electrode and a priming electrode is utilized to cause a write discharging to occur. During a sustain interval, the positive charges are stored on the whole scan electrode, and the negative charges are stored on the whole sustain electrode.
