ABSTRACT:
Disclosed is a PDP image display method and device for dividing an image of each frame displayed on a PDP corresponding to an input video signal into subfields, each subfield corresponding to a bit that represents one of a plurality of luminance weights, combining luminance weights of the subfields, and displaying gray. The subfields include first and second subfield groups. A number of the subfields included in the second subfield group is greater than a number of the subfields included in the first subfield group. At least one of the subfields, which is used for forming low gray, is included in the second subfield group, and a start point of the second subfield group is varied according to a load ratio of the input video signal.
