Abstract

A method of driving a plasma display. Generally speaking, one frame comprises several sub-frames, each of which is displayed by one reset operation, one scan operation and a sustain operation in this driving method, the screen of the plasma display is first divided into a plurality of sub-regions. Then the controller sequentially performs the reset operation, the scanning operation and the sustain operation on these sub-regions. In the driving process, the sustain operation on one of the sub-regions is synchronized with the scan operation of another one of the sub-regions that is subsequently processed, thereby increasing the period of the sustain operation. In addition, the reset operation on one of the sub-regions does not overlap the scan operations and the sustain operations on others sub-regions for preventing signal interference.
