Abstract: PROBLEM TO BE SOLVED: To uniformize display luminance of respective discharge cells, by reducing an after-image phenomenon itself.
SOLUTION: A method is provided for driving a panel having a plurality of discharge cells having a scan electrode and a sustain electrode. One field period is constituted by arranging a plurality of subfields each having an initialization period for generating initialization discharge by the discharge cells, a write period for generating write discharge by the discharge cells and a sustain period for emitting the light by the discharge cells by alternately applying a sustain pulse onto the scan electrode and the sustain electrode. The sustain pulse is either a first sustain pulse for generating a light emission with one peak in the discharge cell or a second sustain pulse for generating a light emission with two peaks in the discharge cell. The rise time of the second sustain pulse applied onto the scan electrode and the rise time of the second sustain pulse applied onto the sustain electrode are set independently of each other based on the percentage of the discharge cells in which the light is emitted during the sustain period of the subfield.
