A plasma display panel displaying grayscales by a combination of brightness weights of a plurality of subfields in a frame. A peak subfield index of a current frame is generated based on a highest grayscale value detected from an input image data of the current frame, wherein the peak subfield index contains information of at least one subfield that is not used in the current frame. At least one period of reset, address, and sustain periods of the at least one subfield that is not used in the current frame is removed in response to a control signal and the peak subfield index of the current frame. The control signal is generated based on a comparison of a peak subfield index of a previous frame that has been delayed by one frame and the peak subfield index of the current frame.
