    • 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.
    • 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。 形成在等离子体显示面板中的多个扫描电极可以分为第一组和第二组,第一组和第二组中的每一个可以被划分成多个子组,然后以子组为基础依次提供扫描信号。 在地址周期的第一周期内提供给属于第一组的两个或更多个子组的扫描偏置电压可以彼此不同,在地址的第二周期中提供给属于第二组的两个或更多个子组的扫描偏置电压 周期可能彼此不同,并且在地址周期的第三周期中提供给属于第一组的任何一个子组和属于第二组的任何一个子组的扫描偏置电压可以彼此不同。 因此,可以高速地驱动面板,并且可以减少由于壁电荷的损失导致的地址错误放电。 因此,可以提高显示图像的图像质量。

    • 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.

    • The present invention relates to a plasma display apparatus. In this plasma display apparatus, a plurality of scan electrodes are divided into first and second groups. An address period includes first and second group scan periods in which scan signals are supplied to the first and second groups, respectively. Scan bias voltages supplied to the first and second groups in at least one of the first and second group scan periods are different from each other. In at least one of a plurality of subfields constituting one frame, a stabilization signal is supplied to at least one of the first and second groups before the scan signal is supplied after a reset signal is supplied. Accordingly, a reduction in the image quality of a display image due to the occurrence of a spot erroneous discharge or address erroneous discharge can be prevented.
