Abstract:
1. A driving method of a plasma display device, the plasma display device being driven by an input video signal during one frame, the one frame being divided into a plurality of subfields, the input video signal of the one frame being divided among the plurality of subfields, each input video signal corresponding to input grayscales, the driving method comprising: detecting a peak value, the peak value being a highest grayscale among the input grayscales of the input video signal of the one frame; converting an input grayscale of the one frame corresponding to the peak value to generate a converted grayscale; applying the converted grayscale to the plasma display device; detecting a total number of sustain discharge pulses applied during the one frame according to a load ratio as a first sustain discharge pulse number utilizing a first sustain discharge pulse number determiner; and determining a total number of sustain discharge pulses applied during the one frame as a second sustain discharge pulse number in correspondence to the peak value and the first sustain discharge pulse number utilizing a second sustain discharge pulse number determiner.
