Abstract
A plasma display device which improves the contrast of an image displayed. The plasma display device includes a plurality of row electrodes formed in pairs corresponding to each display line, a plurality of column electrodes arranged to cross the row electrodes to form a discharge cell corresponding to one pixel at each intersection with a pair of said row electrodes, and a driving controller for controlling driving of the row and column electrodes. A gradation display of input pixel data is performed by dividing one field display period into a plurality of subfields. The driving controller, when one field of input pixel data is displayed, changes the number of reset discharges for initializing all discharge cells in accordance with an average luminance value of input pixel data in the preceding field.
