Classification: CPC G | IPC G

Claim 15:
16. A method of driving a display device, the method comprising:
inputting a first duty ratio and a second duty ratio;
inputting a first frame frequency (F1), a second frame frequency (F2), the number (N) of frequencies, whether or not gradual dimming control is on, and duty ratios of a light emission control signals; and
controlling a frame frequency and gamma correction data so as to be gradually changed such that N frames having N frame frequencies (N is a natural number not less than 3) between a first frame frequency of a first frame and a second frame frequency of a second frame are generated between the first frame and the second frame when the gradual dimming control is in an on state and the duty ratio of the light emission control signal is within a range from the first duty ratio to the second duty ratio, and not controlling the frame frequency and the gamma correction data so as to be gradually changed when the gradual dimming control is in an off state and the duty ratio of the light emission control signal is outside the range from the first duty ratio to the second duty ratio.
