Abstract: In a plasma display panel, a sustain discharge pulse voltage is applied to the scan or sustain electrodes while the address electrode is biased with a ground voltage, and a negative assistant pulse voltage is applied to an electrode that is not receiving the sustain discharge pulse. At least a part of a period for applying the negative assistant pulse is positioned prior to a period of applying the sustain discharge pulse. Discharge efficiency can be improved by applying the negative assistant voltage to the sustain electrode when the sustain discharge is applied to the scan electrode across a long discharge gap.

Abstract: 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.

A board for driving the sustain electrodes and a switch for supplying a ground voltage is eliminated and accordingly manufacturing cost of driving boards is reduced. Various circuits for generating the desirable waveforms and simplifications that do not compromise the effectiveness of the circuits are also presented.

The method includes resetting the electrodes by applying a waveform having a predetermined voltage to the first electrode, applying a fourth voltage to the second electrodes for a predetermined period; selecting cells to be discharged by applying a scan pulse voltage to each of the first electrodes and the third electrodes; and alternately applying a plurality of sustain discharge pulses having a first voltage as peak value to each of the first electrodes and the second electrodes, wherein the step of applying the fourth voltage Ve stops the application of the fourth voltage Ve while the first sustain discharge pulse of the first electrodes continues.

Abstract: 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.

Abstract: A plasma display apparatus may include a PDP having respective pluralities of first electrodes formed in a first direction, and second and third electrodes formed in a second direction perpendicular to the first direction, and a driving apparatus to alternately apply first and second sustain discharge pulses to one of the second electrodes and the third electrodes, the first sustain discharge pulses having a second voltage higher than a first voltage as a peak value and having a first pulse width, and the second sustain discharge pulses having a third voltage lower than the first voltage as a peak value and having a second pulse width shorter than the first pulse width.

Abstract: 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.

Abstract: A plasma display device and a driving method thereof are provided. A sustain pulse is applied to a scan electrode while biasing a sustain electrode at a predetermined voltage during a sustain period. A first sustain pulse having a first magnitude of voltage is applied at lease once to the scan electrode during a first part of the sustain period, and a second sustain pulse and a third sustain pulse are alternately applied to the scan electrode during a second part of the sustain period. The second sustain pulse has a voltage of a second magnitude that is smaller than the first magnitude, and the third sustain pulse has a voltage of a third magnitude that is larger than the second magnitude.

Abstract: 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.

Abstract: A plasma display device and a driving method thereof. In a plasma display panel having an opening or a groove between a scan electrode and a sustain electrode, a driving waveform is applied to the scan electrode and an address electrode while the sustain electrode is biased at a predetermined voltage. Then, since a discharge path is formed through the opening or the groove between the scan and sustain electrodes, a discharge firing voltage may be reduced and misfiring prevented in a sustain period.

Abstract: A plasma display device and a driving method. A driving waveform is applied while sustain electrodes are biased at a predetermined voltage. During an address period of a predetermined first subfield, a first scan pulse of a first voltage is applied to perform write addressing at a discharge cell to be selected at the first subfield, and during an address period of a predetermined second subfield, a second scan pulse having a second voltage that is greater than the first voltage is applied to perform erase addressing at a discharge cell that is not to be selected at the first subfield. A width of the second scan pulse is set to be less than that of the first scan pulse. Accordingly, a separate board for driving the sustain electrode may not be required and the address period can be shortened for a faster address operation.

At least a part of a period for applying the negative assistant pulse is positioned prior to a period of applying the sustain discharge pulse. Discharge efficiency can be improved by applying the negative assistant voltage to the sustain electrode when the sustain discharge is applied to the scan electrode across a long discharge gap.

Abstract: 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.
