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 and defining corresponding pixels at intersections of the address electrode lines relative to the X and Y electrode lines, the method comprising:applying scan pulses sequentially to respective Y electrode lines, and simultaneously applying pulses of a display data signal to respective address electrode lines to produce wall charges at pixels for producing display discharges, and alternately applying pulses for the display discharges at the pixels where the wall charges have been produced, wherein the scan pulses are applied between pulses for the display discharges, to the corresponding Y electrode lines in a plurality of subfields set as driving periods for a time-division gray scale display, and each pulse of the display data signal decreases in voltage as time difference between each pulse of the display data signal and a subsequent pulse for the display discharges decreases.
