    • 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.
    • 本发明涉及驱动等离子体显示面板的方法和采用该方法的等离子体显示装置。 在等离子体显示装置中,形成在等离子体显示面板上的多个扫描电极被分成第一组和第二组,然后提供扫描信号。 当在第一和第二子场的第一子场中提供的扫描偏置电压高于在第一和第二子场的第二子场中提供的扫描偏置电压时,在第二子场中提供的复位信号的最低电压高于在第二子场中提供的最低电压 第一子场 根据本发明的等离子体显示装置,在将多个扫描电极分成两组或更多组并驱动时,根据扫描偏置电压来控制复位信号的最低电压。 因此,可以减少由于壁电荷损失导致的地址错误放电,可以防止斑点的发生,从而可以提高显示图像的图像质量。

    • 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, cycles of scan signals supplied in first and second subfields of a plurality of subfields constituting one frame are identical to each other, 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.

    • 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.
