    • The present invention relates to a plasma display apparatus and driving method thereof, and more particularly, to a plasma display apparatus implementing gray levels and driving method thereof. The plasma display apparatus according to the present invention comprises a plasma display panel in which a plurality of scan electrodes and a plurality of sustain electrodes are formed on a substrate, drivers for driving the plurality of the scan electrodes and the sustain electrodes, and a sustain pulse controller for controlling the drivers to set a total number of sustain pulses applied to the scan electrodes and the sustain electrodes to be at least one or more of a plurality of sub-fields in which a sub-field having an odd number constitutes one frame. The present invention can implement a finer gray level. Accordingly, half-tone noise when implementing a low gray level can be reduced and the picture quality can be improved.
    • 等离子体显示装置及其驱动方法技术领域本发明涉及等离子体显示装置及其驱动方法,更具体地,涉及实现灰度等离子体显示装置及其驱动方法 根据本发明的等离子体显示装置包括:等离子体显示面板,其中在基板上形成有多个扫描电极和多个维持电极,用于驱动多个扫描电极和维持电极的驱动器和维持电极 脉冲控制器,用于控制驱动器,将施加到扫描电极和维持电极的维持脉冲的总数设置为多个子场中的至少一个或多个,其中具有奇数的子场构成一个帧 。 本发明可以实现更精细的灰度级。 因此,可以降低实现低灰度级时的半色调噪声,并且可以提高图像质量。
