Abstract
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.
