A display panel driving method capable of realizing a high definition gradation display while reducing power consumption. In each of a plurality of divisional display periods constituting a unit display period in a video signal, a pixel data writing stage 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 stage 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 periods. A luminance distribution of the video signal is measured every display line on the display panel, and the number of divisional display periods in the unit display period is changed every display line in accordance with the luminance distribution.
