A method and apparatus for driving a plasma display panel (PDP) with discharge cells arranged between a first substrate and second substrate, address electrodes arranged along a first direction, first electrodes and second electrodes arranged along a second direction crossing the first direction on opposite sides of each of a discharge cell, and scan electrodes arranged along the second direction that partition each discharge cell into two discharge spaces. The two discharge spaces of one discharge cell share a scan electrode. By selectively biasing the first electrodes and second electrodes during an address period, the two discharge spaces can be addressed during a first half and a second half of a single address period or during two distinct address periods. Sustain discharge for a single subfield can be generated in the two discharge spaces during a single sustain discharge period or during two distinct sustain discharge periods.
