Abstract: A plasma display panel (PDP) and a method for driving the PDP are described. A falling pulse waveform including alternately repeated voltage falling periods and floating periods that have a first mean slope and another falling pulse waveform including alternately repeated voltage falling periods and floating periods that have a second mean slope gentler than the first mean slope may be applied to sustain electrodes. The first and second slopes may be controlled by controlling the floating time or voltage falling range. In accordance with the present invention, it may be possible to apply pulse waveforms having diverse slopes through a simple driving circuit by floating a voltage charged in or discharged from a panel capacitor.

Abstract: A PDP driving method. A falling ramp voltage is applied to a scan electrode so as to reset a state of wall charges of a discharge cell during a reset period. In this instance, a sustain electrode is maintained at a high voltage during an initial period for applying the falling ramp voltage, and the voltage at the sustain electrode is reduced to a normal voltage at a latter part of the period for applying the falling ramp voltage. Accordingly, the voltage applied to an address electrode is reduced in an address period since an erased amount of the wall charges of the address electrode is reduced during the reset period.

Abstract: A PDP driving method. When a first sustain pulse is applied to a scan electrode during a sustain period, an address electrode is biased by a positive voltage, or the address electrode is biased. Therefore, when a large amount of wall charges are formed on the address and scan electrodes by address discharging during an address period, no main discharge is generated since a high potential of the address electrode is formed in the sustain period.

Abstract: Disclosed are a driving device and a driving method for a plasma display panel (PDP). A panel capacitor is formed by a scan electrode and a sustain electrode. The charges are moved from the panel capacitor to a capacitor by turning on a transistor which is connected between the scan electrode and the capacitor. By this method, the voltage of the panel capacitor is steeply reduced so that a discharge is generated in the panel capacitor. When the voltage of the capacitor increases because of the charges moved from the panel capacitor, the gate-source voltage of the transistor is reduced. As a result, the transistor is turned off so that the scan electrode is floated. Accordingly, the discharge is steeply quenched so that the wall charges are precisely controlled. After the capacitor is discharged, the above-noted operation may be repeated.
