1. plasm display device of realizing having gray shade scale to show with sub-field method, comprise a plasma display panel, this flat board has a plurality of scan electrodes and keeps electrode, they are along same direction extension and be positioned to mutual vicinity, and a plurality of address electrodes, it is along with a plurality of scan electrodes with keep the perpendicular direction of electrode bearing of trend to extend;

  • One keeps the recurrence interval modifier, and it detects the demonstration loading ratio of each height field and recently changes the maintenance recurrence interval of each son field according to detected demonstration load;

    A self-adaptation keeps the pulse number modifier, it is by changing summation to the time in a display field that causes owing to the variation that keeps the recurrence interval, calculate the total variation of time, and increase/reduce the number of the maintenance pulse of each son field according to the total variation of time.
