Abstract
A method for adjusting a gamma curve, a device for adjusting a gamma curve, and a display device. The method for adjusting a gamma curve includes that: a reference duty cycle of a light-emitting control signal is determined according to a duty cycle of the light-emitting control signal at a preset refresh rate; a third refresh rate is determined according to the light-emitting control signal at a first refresh rate, the light-emitting control signal at a second refresh rate and the reference duty cycle, where the third refresh rate is between the first refresh rate and the second refresh rate, and the duty cycle of the light-emitting control signal at the third refresh rate is equal to the reference duty cycle; and the gamma curve is adjusted according to the third refresh rate.
