Abstract
A resetting method includes a line discharge step, an erasure step, and an iteration step. The line discharge step is performed during a part of a first pulse width period. During the first pulse width period since a second subfield corresponding to a first XY-electrode line pair starts after a first subfield corresponding to the first XY-electrode line pair ends, a negative voltage of a first level is applied to all X-electrode lines, and simultaneously, a positive voltage of the first level is applied to all Y-electrode lines. In the line discharge step, a negative voltage of a second level higher than the first level is applied to an X-electrode line of the first XY-electrode line pair, and simultaneously, a positive voltage of a third level higher than the first level is applied to a Y-electrode line of the first XY-electrode line pair, thereby provoking discharges in all discharge cells corresponding to the first XY-electrode line pair. In the erasure step, wall charges are erased from all of the discharge cells corresponding to the first XY-electrode line pair. In the iteration step, the line discharge step and the erasure step are repeatedly performed on all XY-electrode line pairs other than the first XY-electrode line pair.
