摘要： In a driving method of a plasma display device, a final voltage of a falling ramp voltage is set to a discharge firing voltage of all the discharge cells after applying a gradually rising ramp voltage during a reset period. A difference in voltage applied to an address electrode and to a scan electrode is set to be greater than the maximum discharge firing voltage in turn-on discharge cells in an address period. A bias voltage applied in a rising reset period, an address period, and a sustain period of subfields that express low grayscales is increased, and the address electrode is biased with a positive voltage in the sustain period. With this configuration, the problem of worsening the margins by loss of wall charges is solved since addressing is not influenced by the wall charges and performance of expressing low grayscales is increased.

摘要： In a plasma display device and a driving method thereof, a switch for applying a voltage rising waveform to a scan electrode during an idle period and a first period is coupled between the scan electrode and a power source. The switch applies the voltage rising waveform having a first slope by being repeatedly turned on/off according to a first control signal during the idle period, and/or the switch applies the voltage rising waveform having a second slope (having a higher gradient than the first slope) by being repeatedly turned on/off according to a second control signal during the first period. As such, the scan electrode voltage is increased with the first slope during the idle period to perform a more stable reset operation. Also, when the idle period does not exist, the voltage of the scan electrode is increased within the first period to enable a normal reset operation.

摘要： 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.

摘要： 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.
