Abstract: A display device driving method includes: converting a plurality of first luminance signals corresponding to a plurality of pixels to a plurality of second luminance signals; and driving a display component based on the plurality of second luminance signals. The converting includes: calculating a weight corresponding to a lighting period of the display component, based on the plurality of first luminance signals or the plurality of second luminance signals; calculating a cumulative value that is an accumulation of a value corresponding to the weight; calculating, based on the cumulative value, a reduction rate at which each of the plurality of first luminance signals is to be reduced; and calculating the plurality of second luminance signals, based on the reduction rate and the plurality of first luminance signals.

Abstract: A display device driving method of driving a display device that includes a display panel including plural pixels, the display device driving method including: calculating, for each of the plural pixels, cumulative stress that is an accumulation of stress corresponding to an output luminance of the pixel; selecting, 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 plural pixels and indicating a relationship between the cumulative stress and an efficiency residual ratio that indicates a degradation degree of the pixel; determining the efficiency residual ratio, based on the one correlation data item and the cumulative stress; and correcting, for each of the plural pixels, a luminance signal corresponding to the pixel, based on the efficiency residual ratio that corresponds to the pixel and is determined in the determining.
