Plasma display apparatus
A PDP apparatus in which degradation in image quality such as display missing points does not occur, even if the peak luminance is increased, has been disclosed. In the PDP apparatus, the display load ratio of each subfield is detected and a sustain pulse cycle is changed according to the display load ratio of each subfield. Moreover, an adaptive sustain pulse number change means is provided, which calculates the total amount of variations in time by summing the variations in time in a display field caused by the changes in the sustain pulse cycles and increases/decreases the number of sustain pulses of each subfield according to the total amount of variations in time.
