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 parallel first and second electrodes covered with dielectric and a third electrode 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. The addressing comprises effecting an operation of producing wall charges having the same polarity on the dielectric layers over the first and second electrodes before an operation of producing discharge between the second and third electrodes for addressing, so that the discharge for addressing occurs only between the second and third electrodes.
