A PDP apparatus is disclosed in which degradation in image quality such as display missing points does not occur, even if the peak luminance is increased. 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 (29) 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 duration of a sustain pulse cycle within respective subfields and increases/decreases the number of sustain pulses of each subfield according to the total amount of variations in time. The ratio between the different subfields in respect of the number of sustain pulses is the same after said changes in the sustain pulse cycles as before said changes having taken place. <IMAGE>A PDP apparatus is disclosed in which degradation in image quality such as display missing points does not occur, even if the peak luminance is increased.
