Patent ID: 8427405

Claim:
A method of driving an image display device including a plurality of pixel circuits each having a light emitting element; a power source line connected in common to the plurality of pixel circuits, supplying a current from one end side toward an opposite end side of a light emission region in which the plurality of pixel circuits are arranged; and an image signal line for applying a potential corresponding to image data to the plurality of pixel circuits, the method comprising: a deriving step of deriving a second correction value based on a first correction value derived from tone data of the plurality of pixel circuits included in a first light emission region extending halfway from the opposite end side to the one end side of the light emission region, a resistance of the power source line, and tone data of the plurality of pixel circuits included in a second light emission region arranged closer to the one end side than the first light emission region; an adjusting step of adjusting a tone indicated by the image data based on the second correction value; a setting step of setting a potential of the plurality of pixel circuits arranged in the second light emission region or a potential of the plurality of pixel circuits arranged closer to the one end side than the second light emission region by applying a potential corresponding to the tone adjusted in the adjusting step to the image signal line; and a light emission step of causing each of the light emitting elements to emit light by supplying a current from the power source line to each of the light emitting elements, wherein the first light emission region is an N th light emission region (N is a natural number) extending halfway from the opposite end side to the one end side of the light emission region and the second light emission region is an (N+1) th light emission region arranged closer to the one end side than the N th light emission region, and the first correction value is N th correction value derived from tone data of the plurality of pixel circuits that are included in the N th light emission region and the second correction value is (N+1) th correction value derived based on the N th correction value, the resistance of the power source line, and tone data of the plurality of pixel circuits included in the (N+1) th light emission region.
