ABSTRACT:
An address pulse width is reduced so that a display period for driving a plasma display panel (PDP) can be made longer. The PDP comprises cells, each cell having first and second electrodes covered with dielectric and a third electrode covered with dielectric disposed in a direction crossing the first and second electrodes. A method of driving the PDP comprises addressing ones of the cells to be illuminated for displaying, by applying, between the second and third electrodes of the respective cells to be illuminated, a preparatory address pulse having a pulse width that produces no discharge, and by subsequently applying therebetween main address pulses, each main address pulse having a pulse width that produces discharge.
