Abstract of the DisclosureA display device for displaying pictures by sequentially performing an address period and a sustain period, such as, a plasma display panel (PDP), is provided. The pixels of a panel are arranged into a plurality of groups, and an address period and a sustain period are sequentially performed on the pixels of individual groups. While an address period is being performed on the pixels of a certain group, the pixels of other groups are idle. While a sustain period is being performed on the pixels of the group subsequent to the address period, a sustain period is selectively performed on the pixels of each of other groups that have already undergone an address period. Accordingly, a sustain discharge operation is performed within a short period of time after an address operation is performed on each of the pixels, so that a stable sustain discharge occurs.
