Abstract:
A method for driving a plasma display panel having front and rear substrates opposed to and facing each other, X and Y electrode lines between the front and rear substrates parallel to each other, and address electrode lines orthogonal to the X and Y electrode lines, defining corresponding pixels at intersections, wherein a scan pulse is applied to respective Y electrode lines with a time difference and corresponding display data signals are simultaneously applied to respective address electrode lines to form wall charges at pixels at which light is to be displayed, and pulses for producing a display discharge are alternately applied to the X and Y electrode lines to cause a display discharge at the pixels where the wall charges have been formed, the driving method including applying the scan pulse progressively to the corresponding Y electrode lines of a plurality of sub fields established as driving periods for a time-division gray scale display, and changing the scanning order for the plurality of subfields according to the field in a unit display period.
