Display device driving method and display device

A display device driving method of driving a display device that includes a display panel including a plurality of pixels, the display device driving method comprising:

• calculating, for each of the plurality of pixels, cumulative stress that is an accumulation of stress corresponding to an output luminance of the pixel;
• determining, for each of the plurality of pixels, an efficiency residual ratio indicating a degradation degree of the pixel, based on the cumulative stress and correlation data that corresponds to the pixel and indicates a relationship between the cumulative stress and the efficiency residual ratio;
• generating, for each of the plurality of pixels, a first correction signal by correcting a luminance signal corresponding to the pixel based on the efficiency residual ratio that corresponds to the pixel and is determined in the determining of the efficiency residual ratio;
• and
• generating a second correction signal by correcting the first correction signal based on an additional gain signal input to the display device.

A display device that includes a display panel including a plurality of pixels, the display device comprising:

• a cumulative stress calculator that calculates, for each of the plurality of pixels, cumulative stress that is an accumulation of stress corresponding to an output luminance of the pixel;
• a selector that selects, based on a selection signal input to the display device, one correlation data item from among a plurality of correlation data items each corresponding to a different one of the plurality of pixels and indicating a relationship between the cumulative stress and an efficiency residual ratio that indicates a degradation degree of the pixel;
• an efficiency residual ratio determiner that determines the efficiency residual ratio, based on the one correlation data item and the cumulative stress;
• and
• a corrector that corrects, for each of the plurality of pixels, a luminance signal corresponding to the pixel based on the efficiency residual ratio that corresponds to the pixel and is determined by the efficiency residual ratio determiner.
