1. A method of compensating a brightness for a display device, comprising:
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 in the multiple frames of pictures according to the display brightness data of the multiple frames of pictures;
determining a reference picture and at least one frame of to-be-compensated picture in the multiple frames of pictures according to the brightness coefficient; and
determining a grayscale compensation value of the at least one frame of to-be-compensated picture, so that a ratio of a display brightness of each frame of to-be-compensated picture in the at least one 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.
