    Abstract: A method and device of compensating a brightness for a display device and a method and device of driving a display device are provided. The method of compensating a brightness includes: acquiring display brightness data of multiple frames of pictures displayed after a display picture of the display device is switched from a first grayscale value to a second grayscale value; determining a brightness coefficient of each frame of picture according to the display brightness data; determining a reference picture and at least one frame of to-be-compensated picture according to the brightness coefficient; and determining a grayscale compensation value, so that a ratio of a display brightness of each frame of to-be-compensated picture displayed by the display device to a display brightness of the reference picture displayed by the display device is greater than or equal to a preset first brightness threshold.
