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 and parallel to each other, and address electrode lines orthogonal to the X and Y electrode lines, to define corresponding pixels at intersections, the method comprising applying scan pulses to respective groups of Y electrode lines with a time difference and simultaneously applying corresponding display data signals to respective address electrode lines to form wall charges at pixels where a display discharge is to occur, and alternately applying pulses for a display discharge to the X and Y electrode lines to cause a display discharge at the pixels where wall charges have been formed, wherein, as a time difference between (i) a first pulse of the pulses for display discharges, and (ii) pulses of the display data signals applied to pixels for a display discharge before application of the first pulse becomes larger, widths of the pulses of the display data signals applied to pixels where a display discharge is to occur and of corresponding scan pulses are increased.
