Method for driving plasma display panel
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. A scan pulse is sequentially applied to the respective Y electrode lines at a predetermined time difference and the corresponding display data signals are simultaneously applied to the respective address electrode lines to produce wall charges at pixels where a discharge display discharge is to take place and pulses for 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 produced. The scan pulse is progressively applied between pulses for a display discharge, to the corresponding Y electrode lines of subfields set as driving periods for time-division gray scale display, and the voltage of the display data signal applied to the pixels where a discharge display is to take place as a time difference between (i) the first pulse, among the pulses for a display discharge and (ii) the pulse of the display data signal applied to the pixels where a discharge display is to take place before application of the first pulse, becomes larger.
