Abstract:
1. A panel driving method for driving pixels of a panel, wherein 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, a frame period for displaying a single image is divided into a plurality of sub-fields to each of which a predetermined gradation weight is allocated, the sub-fields are selectively operated to determine a gradation of visual brightness for each cell, and for at least one of the sub-fields, the method comprising: during a write/sustain mixed period, sequentially applying, address signals, during an address period, and sustain signals, during a sustain period, to the pixels of one of the plurality of groups before applying address signals and sustain signals to the pixels of another of the plurality of groups, wherein the step of applying address signals and sustain signals is repeated for each of the plurality of groups and while a sustain period is being performed on the pixels of one of the plurality of groups, the pixels of others of the plurality of groups to which address signals and sustain signals have already been applied being are selectively subjected to sustain periods; during a concurrent sustain period, performing a predetermined length of sustain period concurrently on the pixels of all of the plurality of groups; and during a brightness compensation period, selectively performing an additional sustain period on the pixels of each of the plurality of groups so that the pixels of each of the plurality of groups satisfy a predetermined gradation allocated to the sub-field.
