Abstract:
A display device includes: luminance converter that converts an input gradation value into a target luminance value corresponding to the input gradation value; correction calculator that calculates an output gradation value from the target luminance value and calculates a corrected luminance value from the output gradation value using an efficiency residual rate; cumulative stress calculator that updates the efficiency residual rate using a cumulative stress amount obtained by converting a stress amount on the light emitting element calculated from the corrected luminance value into a first stress amount at a reference current and accumulating a second stress amount obtained by converting the converted first stress amount according to a frame rate; and stress amount converter that converts the first stress amount into the second stress amount by multiplying the first stress amount by a conversion coefficient corresponding to the frame rate obtained from the video signal.
