Patent ID: 7209100

Claim:
A method for driving a display panel with a plurality of pixel cells formed therein in accordance with a video signal, comprising: a resetting step for resetting all of said pixel cells into a light-emitting cell state only in one of a plurality of divided display periods at a head position of a unit display period, said plurality of divided display periods constituting said unit display period; a writing step for selectively setting said pixel cells to a non-light-emitting cell state in accordance with pixel data corresponding to said video signal only in one of said divided display periods; a light emitting step for allowing only pixel cells in said light-emitting cell state to emit light a number of light emitting times assigned correspondingly to each of weights assigned to said respective divided display periods a brightness range measuring step for measuring a range of brightness of said video signal for each said unit display period; a light emission number changing step for changing said number of light emitting times to be assigned to said one of divided display periods at the head position, in accordance with said range of brightness of said video signal measured in said brightness range measuring step, wherein in said light emission number changing step said number of light emitting times assigned to said one of said divided display periods at the head position is changed in such a way that said number of light emitting times increases as a lowest brightness level in said range of brightness rises.
