Abstract
When a current frame of a video expresses only grayscales less than a reference grayscale, a sustain pulse applying period and a holding period are alternately provided in a sustain period of at least one subfield having a weight greater than a reference weight in all of the discharge cells of a plasma display panel, thereby reducing power consumption in the plasma display panel. In the sustain pulse applying period, sustain pulses alternately having a first voltage and a second voltage less than the first voltage are applied in opposite phases to first electrodes and second electrodes of the plasma display panel. In the holding period, the first electrodes and/or the second electrodes are maintained at the first voltage.
