    • The present invention provides a gray level display AC-type PDP driving method comprising (a) dividing a single image frame into n number of subframes, each of the subframes having predetermined number of sustaining pulses; (b) selecting scan electrodes whose number is identical to the number of said subframes, assigning specific subframes to said selected scan electrodes, sequentially providing scanning pulses having different phases on said selected scan electrodes and applying addressing pulses on said data electrodes in order to designate pixels to be displayed, and alternately supplying the predetermined number of sustaining pulses onto the selected scan electrodes and said data electrodes, to thereby display said assigned subframes for said selected display lines; (c) shifting by one or more than scan electrode(s) from each of said selected scan electrodes; and (d) repeating said shifting of step (c) and displaying of said assigned subframes until each of said divided subframes is displayed for all the display lines, to thereby display an image frame. According to the present invention, it is possible to eliminate a suspending time and to provide advantages of advanced driving stability, high luminance and improved contrast.
    • 本发明提供了一种灰度显示AC型PDP驱动方法,包括:(a)将单个图像帧划分为n个子帧,每个子帧具有预定数量的维持脉冲; (b)选择数量与所述子帧数相同的扫描电极,将特定子帧分配给所述选择的扫描电极,在所述选择的扫描电极上依次提供具有不同相位的扫描脉冲,并在所述数据电极上施加寻址脉冲,以指定 像素,并且将预定数量的维持脉冲交替地提供到所选择的扫描电极和所述数据电极上,从而显示所选择的显示行的所分配的子帧; (c)从每个所述选择的扫描电极移动一个或多个扫描电极; 和(d)重复所述步骤(c)的所述移位和所述分配的子帧的显示,直到对于所有的显示行显示所述划分的子帧的每一个,从而显示图像帧。 根据本发明,可以消除悬挂时间并提供先进的驱动稳定性,高亮度和改进的对比度的优点。
