Abstract
A plasma display apparatus has scan electrodes, data electrodes intersecting the scan electrodes, and discharge cells disposed at the intersections of the scan electrodes and the data electrodes. A scan driving unit scans the scan electrodes. A data driving unit supplies a data signal to the data electrodes, and a control unit controls the scan driving unit and the data driving unit. The control unit detects data patterns of input data to detect the load of data, and controls the scan of the scan driving unit according to the load. As such, if the scan electrodes are divided into two or more groups and supplied with scan signals, variation in the polarity of data signals applied to the data electrodes can be minimized.
