Abstract
A display panel driving method capable of performing a good intermediate luminance display corresponding to an input video signal. A unit display period in a video signal is composed of a plurality of divisional display periods. In each of the divisional display periods, a pixel data writing process is performed for setting each of pixel cells to either a light emitting cell or a non-light emitting cell in accordance with pixel data corresponding to the video signal, and a light emission sustain process is performed for causing only the light emitting cells to emit light a number of light emissions allocated in correspondence to a weighting factor applied to each of the divisional display period. A luminance distribution of the video signal is measured every display line on the display panel, and the number of light emissions allocated to each of the light emission sustain process is changed every display line in accordance with the luminance distribution.
