Image display device and method of driving the same

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 Nth 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 Nth light emission region, and
• the first correction value is Nth correction value derived from tone data of the plurality of pixel circuits that are included in the Nth light emission region and the second correction value is (N+1)th correction value derived based on the Nth 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.
