摘要： The present invention relates to a plasma display apparatus and, more particularly, to a method of driving a plasma display panel. The plasma display apparatus includes a plasma display panel including a plurality of scan electrodes and sustain electrodes formed on an upper substrate, and a plurality of address electrodes formed on a lower substrate, and a driver for supplying driving signals to the plurality of electrodes. The plurality of scan electrodes are divided into first and second groups and then supplied with scan signals, and scan bias voltages supplied to the first and second groups in at least any one period of an address period are different from each other. In at least one of a plurality of subfields constituting one frame, a width of a first sustain signal of a plurality of sustain signals supplied during a sustain period is larger than a width of each of the remaining sustain signals.

摘要： The present invention relates to a method of driving a plasma display panel and a plasma display apparatus employing the same. A plurality of scan electrodes formed in a plasma display panel may be divided into first and second groups, each of the first and second groups may be divided into a plurality of subgroups and then sequentially supplied with scan signals on a subgroup basis. Scan bias voltages supplied to two or more subgroups belonging to the first group in a first period of the address period may be different from one another, scan bias voltages supplied to two or more subgroups belonging to the second group in a second period of the address period may be different from one another, and scan bias voltages supplied to any one subgroup belonging to the first group and any one subgroup belonging to the second group in a third period of the address period may be different from each other. Accordingly, the panel can be driven at high speed and an address erroneous discharge due to the loss of wall charges can be reduced. Consequently, the image quality of a display image can be improved.

摘要： The present invention relates to a method of driving a plasma display panel and a plasma display apparatus employing the same. In the plasma display apparatus, a plurality of scan electrodes formed in a plasma display panel are divided into first and second groups and then supplied with scan signals. When a scan bias voltage supplied in a first subfield of first and second subfields is higher than that supplied in a second subfield of the first and second subfields, a lowest voltage of a reset signal supplied in the second subfield is higher than that supplied in the first subfield. In accordance with the plasma display apparatus of the present invention, the lowest voltage of the reset signal is controlled according to the scan bias voltage in dividing the plurality of scan electrodes into two or more groups and driving them. Accordingly, an address erroneous discharge due to the loss of wall charges can be reduced, the occurrence of spots can be prevented and therefore the image quality of a display image can be improved.
