ABSTRACT:
A method for driving a cell of a plasma display panel in a duration of a frame, in which the frame contains a plurality of subfields. The method comprises setting a selected subfield in the frame of at least one cell of a scanning line to a selected state; setting each one of the subfields preceding the selected subfield to a state opposite the selected state; setting each one of the subfields succeeding the selected subfield in the frame to the same state as a corresponding subfield of a corresponding cell in an adjacent previous scanning line; and driving the one cell by turning the cell into either an ON or OFF condition from the selected subfield throughout the succeeding subfields in the frame based on the selected state of the selected subfield. Another method is to set each one of the subfields succeeding the selected subfield in the frame, based on states of corresponding subfields of corresponding cells in an adjacent previous scanning line and an adjacent next scanning line. Another aspect of the present invention is a plasma display panel driven by the aforementioned methods.
