Method for driving plasma display panel with display discharge pulses having different power levels
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 and parallel to each other and address electrode lines orthogonal to the X and Y electrode lines, to define corresponding pixels at intersections. In the driving method, a scan pulse is applied to the respective Y electrode lines with a time difference and the corresponding display data signals are simultaneously applied to the respective address electrode lines to form wall charges at pixels where a display discharge is to occur. 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 formed. Also, the pulses for display discharges simultaneously applied to the X electrode lines start after the pulses for display discharges simultaneously applied to the Y electrode lines terminate, and the scan pulses and the corresponding display data signals are applied after the pulses for display discharges simultaneously applied to the X electrode lines terminate and before the pulses for display discharges simultaneously applied to the Y electrode lines start. The power levels of pulses for display discharges simultaneously applied to the Y electrode lines are greater than the power levels of pulses for display discharges simultaneously applied to the X electrode lines.
