Abstract: A plasma display device is provided. In the plasma display device, a plurality of scan electrodes are divided into one or more scan electrode groups, and different driving signals are applied to the scan electrode groups. More specifically, different scan bias voltages are applied to the scan electrodes during a scan period, and different signals are applied to the scan electrodes during a set-down period of a reset period. Therefore, it is possible to stabilize an address discharge in scan electrodes to which scan signals are applied late.

Abstract: A plasma display device is provided. In the plasma display device, a plurality of scan electrodes are divided into one or more scan electrode groups, and different driving signals are applied to the scan electrode groups. More specifically, a minimum voltage detected during a set-down period of a reset period is made to be discrepant from a scan voltage, thereby reducing the amount by which wall charge is erased and stabilizing an address discharge. In addition, different driving signals are applied to a plurality of scan electrodes, and thus, it is possible to stabilize an address discharge even in scan electrodes to which a scan signal is applied late.

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.
