    • The present invention relates to a plasma display apparatus. The plasma display apparatus includes a first layer and a second layer over an upper substrate of a plasma display panel. The first layer emits light having a peak at a first wavelength region with light emitted from a discharge space. The second layer emits light having a peak at a second wavelength region lower than the first wavelength region with light emitted from a discharge space. The first layer and the second layer are disposed over a dielectric layer of the upper substrate. 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 one period of an address period are different from each other. Accordingly, the occurrence of address erroneous discharge due to the loss of wall charges can be reduced and the discharge efficiency can be enhanced. Further, consumption power for panel driving can be saved and driving margin of a panel can be secured sufficiently.

    • 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.
