ABSTRACT:
Disclosed is a driving method of a PDP (Plasma Display Panel) which removes excess charged particles collected on the outside of a display screen through a reciprocating action of a scan order. The driving method of a PDP (Plasma Display Panel) includes dividing a field of an input video signal into a plurality of sub-fields having brightness weights and applying a scan pulse. Next, applying an input video data signal pulse to address electrodes to have an address period designating cells to be displayed and a sustain period applying a sustain pulse to the designated cells according to the brightness weight of the corresponding sub-field, wherein the plurality of sub-fields include sub-fields, which have the address period applying the scan pulse to the scan electrodes to the number of N in order of 1, 2, . . . , N−1 and N, and sub-fields, which have the address period applying the scan pulse to the scan electrodes in order of N, N−1 , . . . , 2 and 1.
