ABSTRACT:
A panel driving method for driving pixels of a panel. The pixels are classified into a plurality of groups and the pixels of one of the plurality of groups are addressed and sustain-discharged before the pixels of another one of the plurality of groups are addressed and sustain discharged. In the panel driving method, a frame period for displaying a single image is divided into a plurality of sub-fields, each of which has a predetermined gradation, and the sub-fields are selectively operated to determine a gradation of visual brightness for each cell. In at least one of the sub-fields, an address period and a sustain period are sequentially performed on the pixels of each of the groups. While an address period is being performed on the pixels of a one of the groups, the pixels of other groups are idle. While a sustain period subsequent to the address period is being performed on the pixels of one of the group, a sustain period is selectively performed on the pixels of each of other groups that have already undergone an address period.
