摘要： A driving method of a plasma display panel including a discharge space defined by a plurality of scan electrodes, a plurality of sustain electrodes and a plurality of address electrodes for preventing or reducing a misfiring address discharge. In the driving method, a low scan pulse voltage, which is lower than a low scan pulse voltage applied to a previously addressed scan electrode, is applied to a scan electrode which is scanned later in an address period. A low scan pulse voltage applied in an address period of a subfield having a sub-reset period is established to be lower than a low scan pulse voltage applied in an address period of a subfield having a main reset period.

摘要： A method for driving a plasma display panel having a plurality of scan, sustain, and address electrodes is presented. Reset, address, and sustain discharge are performed by applying a driving waveform to a scan electrode while the sustain electrode is biased at a ground voltage. Address electrode is set to be at a positive voltage while the voltage of the scan electrode is gradually increased during the reset period. The foregoing driving voltage scheme obviates the need for a separate driving board for the sustain electrode. A single integrated board is sufficient for driving the scan and sustain electrodes. Various slopes for rising and falling portions of the scan waveform during the reset period are presented. A falling only reset period in second and subsequent subfields is used.

摘要： Reset, address, and sustain operations of a plasma display device are performed by applying a driving waveform to a scan electrode while biasing a sustain electrode at a ground voltage allowing a driving board for driving the sustain board to be eliminated. Since a low voltage is applied to the scan electrode while biasing the sustain electrode at the ground voltage during the reset period, a potential formed by a wall charge may be greater at the scan electrode than at the address electrode. In addition, a misfiring discharge may be prevented during the sustain period when a low voltage applied to the scan electrode during the sustain period is set to be greater than the scan voltage of a scan pulse applied to the scan electrode during the address period.

摘要： A plasma display device and a driving method therefor are provided. The driving method includes gradually decreasing a voltage of a first electrode during a reset period, biasing a voltage of a second electrode to a first voltage during a first period of the falling period, and biasing the second electrode to a second voltage lower than the first voltage during a second period of the falling period. The first voltage is higher than a voltage that is applied to the second electrode during an address period. Therefore, as a voltage of the second electrode is biased to a predetermined voltage in a falling period of a reset period, wall charges of the scan electrode Y and the sustain electrode X can be fully erased.

摘要： A driving method of a plasma display panel, the plasma display panel including a plurality of first electrodes and a plurality of second electrodes, and a plurality of third electrodes which lie in a direction perpendicular to that of the first electrodes and the second electrodes. The second electrode is biased at a first voltage during the reset period, the address period, and the sustain period. A voltage of the first electrode is increased from a second voltage to a third voltage. The voltage of the first electrode is decreased from a fourth voltage to a fifth voltage during the reset period. The fifth voltage is lower than the lower voltage among the voltages that are applied for a sustain discharge in the sustain period.

摘要： A plasma display device and a driving method thereof. During a sustain period of a first subfield, a sustain discharge alternating waveform alternating between a Vs voltage and a −Vs voltage is applied to a sustain electrode while a scan electrode is supplied with a constant reference voltage. During an initialization period of a second subfield consecutive to the first subfield, a voltage of the sustain electrode is gradually decreased from a ground voltage to a negative voltage while a scan electrode is applied with the ground voltage, causing a weak discharge to be generated between the scan electrode and the sustain electrode and between the sustain electrode and an address electrode so that wall charges formed on each electrode are partially erased. Accordingly, a scan electrode driver does not need a power recovery circuit by applying the sustain discharge pulse only to the sustain electrode. In addition, an appropriate wall charge distribution can be achieved thus eliminating misfiring.
