ABSTRACT:
A method for driving a plasma display panel is provided, in which one field time is divided into a plurality of sub-field times having different light emitting times from each other. At least one sub-field time is longer than others to have a light emitting time longer than the other sub-field times. In each sub-field time, a state is selected from a light emission state and a non-light emission state to provide a predetermined gradation of an image to be displayed without decreasing light efficiency.
