Classification: CPC G  H | IPC G  H

Claim 18:
19. A display device comprising:
a display panel including a pixel emitting light with a luminance corresponding to a duty of a duty control signal and a data signal; and
a driver that generates the duty control signal and the data signal and receives a sensing signal from the pixel, wherein
the driver varies a voltage level of the data signal in a first grayscale section in which a grayscale corresponding to the data signal is greater than or equal to a reference grayscale, and varies a duty ratio of the duty control signal in a second grayscale section in which the grayscale is less than the reference grayscale, and
the driver corrects the duty ratio of the duty control signal based on the sensing signal.
