Abstract
A driving method for a plasma display panel. The plasma display panel has a plurality of plasma display units. Each unit includes a first and second electrode forming a capacitor-like load, and a passivation layer formed above the first and second electrodes. The plasma display unit is filled with a dischargeable gas that generates wall charges above the passivation layer after application of a potential difference by a driving circuit. The driving circuit includes a resonant unit electrically connected to the first electrode of the plasma display unit. Firstly, the driving circuit charges the resonant unit. Next, the driving circuit resonates the capacitor-like load of the plasma display unit together with the resonant unit. By using the smooth slope of a sinusoidal waveform, abrupt discharge between the first and second electrodes can be avoided.
