Patent ID: 7598931

Claim:
A plasma display apparatus including scan electrodes, data electrodes intersecting the scan electrodes, and discharge cells at the intersections of the scan electrodes and the data electrodes, the apparatus comprising: a scan driving unit that scans the scan electrodes in a scan sequence; a data driving unit that supplies a data signal to the data electrodes; and a control unit for controlling the scan driving unit and the data driving unit, wherein the control unit detects at least one predetermined data pattern of input data and determines if a data load associated with the at least one data pattern exceeds a first reference point or a second reference point, and controls the scan sequence according to the data load, wherein the control unit detects at least two data patterns, the at least two data patterns includes at least one of a first data pattern in which a high level and a low level alternate in both a row direction and a column direction of the discharge cells, and a second data pattern in which a high level and a low level alternate in the row direction and alternate in groups of two in the column direction, wherein the control unit controls the scan driving unit to scan the scan electrodes in a first scan sequence if the data load of the first data pattern exceeds the first reference point, and the control unit controls the scan driving unit to scan the scan electrodes in a second scan sequence, different from the first scan sequence, if the data load of the second data pattern exceeds the second reference point, and wherein the first scan sequence is a sequence in which the scan electrodes are divided into two groups and then scanned and the second scan sequence is a sequence in which the scan electrodes are divided into four groups and then scanned.
