PROBLEM TO BE SOLVED: To improve the driving voltage margin at the time of driving a plasma display panel by applying the narrow width pulse as an eliminating pulse for eliminating the only cell lighted in the last sub field for elimination discharge. SOLUTION: Full surface writing discharge is not performed in a sub field sFn+1, and the elimination pulse of the narrow width pulse having 2 μs or less of pulse width is applied to an X electrode so as to eliminate a wall charge. The narrow width pulse concludes the apply of the pulse voltage immediately after forming discharge, and almost of the charged particles generated at the time of discharge are left in a discharging cell space, and attracted to the wall charge on a panel dielectric layer by the electrostatic force, and connected again on the wall surface so as to be eliminated. Opposite electrode electrical potential during the maintenance discharge period of a three-electrode structure panel is set at an intermediate value of an electrical potential between the maintenance discharge electrodes so as to stabilize the operation of the panel. With this structure, even at the time of discharge for eliminating the narrow width pulse having a pulse width at 2 μs or less, the opposite electrode is maintained at a positive electrode electrical potential during the maintenance discharge period. |
