Abstract:
1. A device for operating a plasma display panel (PDP) having sustain electrode lines, upper and lower address electrode lines, and a plurality of successive upper scan electrode lines and a plurality of successive lower scan electrode lines, comprising: a first Y operating part for providing a scan pulse to the upper scan electrode lines, each of the successive upper scan electrode lines being provided with a first scan pulse in a first sequence, the first sequence being changed at every new frame; a second Y operating part for providing a scan pulse to the lower scan electrode lines, each of the successive lower electrode lines being provided with a second scan pulse in a second sequence, the second sequence being changed at every new frame; a Z operating part for operating the sustain electrode lines; a first X operating part for operating the upper address electrode lines; and a second X operating part for operating the lower address electrode lines, wherein the first and second sequences are changed at every new frame so that sequences of the first and second scan pulses applied in one sub-field of one frame are different from sequences of the first and second scan pulses applied in a same number sub-field in a succeeding frame.
