Abstract
A method and an apparatus for driving an image display device, such as, a plasma display panel, to represent a gradation. The pixels of a panel are classified into a plurality of groups, and one frame period is divided with time into n subfields. An address period and a sustain period are sequentially executed on each of the groups during at least two of the n subfields. While the pixels of one group are undergoing an address period during a subfield, the pixels of the other groups remain idle. While the pixels of one group are undergoing a sustain period, the pixels of groups that have already been addressed also undergo the sustain period. During one subfield, different gradation weights are allocated to the groups. A gradation of visual brightness for each pixel is determined by performing an address period for either all or some of the groups during at least two subfields. The panel driving method for representing gradation is adaptable.
