Abstract:
A display panel driving method for driving a display panel having pixel cells formed at each of intersections of a plurality of row electrodes corresponding to display lines with a plurality of column electrodes arranged to intersect said row electrodes to provide a display in gradation representation in accordance with a video signal, said method comprising:performing, in each of a plurality of divided 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 times of light emission allocated thereto corresponding to a weighting factor applied to each of said divided display periods; sequentially writing said pixel data of every display line into each of said pixel cells on display lines belonging to a first display region in a display screen on said display panel; and stopping writing said pixel data into each of said pixel cells on display lines belonging to a second display region in said display screen, or simultaneously setting said pixel cells into said non-light emitting cell.
