Abstract
A plasma display driving system. The system includes a controlling circuit, a scan driver, and a data driver. The controlling circuit outputs a first scan driving pulse and a second scan driving pulse, and a third scan driving pulse during addressing period. The frequency of the first scan driving pulse is higher than the second scan driving pulse, and the frequency of the second scan driving pulse is higher than the third scan driving pulse. The scan driver drives the first scanning electrodes, the second scanning electrodes, and the third scanning electrodes according to the first scan driving pulse, the second scan driving pulse, and the third scan driving pulse respectively. The data driver drives the first data electrodes, the second data electrodes, and the third data electrodes responding to the first scanning electrodes, the second scanning electrodes and the third scanning electrodes when the scanning electrodes are driven.
