Abstract
A plasma display panel with a drive circuit that divides a field into a plurality of sub-fields with each sub-field including a write period, a discharge sustain period and an erase period. In the discharge sustain period at least one of a plurality of pulses applied in a later part of the discharge sustain period has a larger pulse width than a pulse applied in an earlier part of the discharge sustain period and in the erase period, a narrow pulse is applied to a pair of electrodes extending across each of a plurality of discharge cells. The narrow pulse has a pulse height lower than a discharge firing voltage of the plurality of discharge cells and a smaller pulse width than the pulses applied in the discharge sustain period.
