ABSTRACT:
Disclosed herein is a method for driving a display panel that provides excellent halftone brightness at low power consumption. A unit display period of a video signal is constituted by a plurality of divided display periods. In each of the divided display periods, the pixel data write process in which each of the pixel cells is set to either a light-emitting cell or a non-light-emitting cell in accordance with pixel data corresponding to the video signal is carried out. In addition, in each of the divided display periods, the light emission sustain process in which only the aforementioned light-emitting cell is allowed to emit light for the number corresponding to a weight assigned to each of the divided display periods is carried out. In accordance with the brightness level of the video signal, the number of light emissions that is to be assigned to each of the divided display periods is changed.
