Abstract:
A method for resetting to normalize discharge cells of each of XY-electrode line pairs while applying a positive voltage of a first magnitude and a negative voltage of the first magnitude alternately to all X-electrode lines and all Y-electrode lines in a surface discharge type plasma display panel, comprising steps of:(a) applying simultaneously a negative voltage of a second magnitude to an X-electrode line of a first XY-electrode line pair and a positive voltage of a third magnitude to a Y-electrode line of the first XY-electrode line pair, so as to provoke discharges in all discharge cells corresponding to the first XY-electrode line pair during pulse period; (b) after a first subfield corresponding to the first XY-electrode line pair ends, simultaneously applying the positive voltage of the first magnitude to all of the Y-electrode lines; (c) erasing wall charges from all of the discharge cells corresponding to the first XY-electrode line pair, and (d) repeating steps (a), (b) and (c) on rest of XY-electrode line pairs, wherein both the second magnitude and the third magnitude are greater than the first magnitude.
