Display panel driving method

A display panel driving method for driving a display panel having a plurality of pixel cells arranged in matrix in accordance with a video signal, said method comprising:

• performing, in each of a plurality of divisional display periods of a unit display period in said video signal, a pixel data writing process for setting each of said pixel cells to either a light emitting cell or a non-light emitting cell in accordance with pixel data corresponding to said video signal to write the pixel data, and a light emission sustain process for causing only said light emission cells to emit light a number of light emissions allocated thereto corresponding to a weighting factor applied to each of said divisional display periods;
• obtaining a luminance distribution of said video signal every plural display lines on said display panel;
• and
• changing said number of light emissions allocated to said divisional display period every plural display lines in accordance with said luminance distribution.
