Display screen brightness correction method and device, electronic equipment and storage medium

The invention relates to a display screen brightness correction method, a display screen brightness correction device, electronic equipment and a storage medium. The display screen brightness correction method comprises the steps of determining a gray level brightness mean value corresponding to display of a standard frame image and a gray level compensation brightness value corresponding to a to-be-corrected frame image based on gray level brightness when each frame image of a plurality of display screens is displayed; and based on the gray scale compensation brightness value corresponding to the to-be-corrected frame image, the gray scale brightness mean value corresponding to the standard frame image and the brightness regulation duty ratio when the standard frame image is displayed, determining the brightness regulation duty ratio corresponding to the to-be-corrected frame image when the to-be-corrected frame image is to be displayed. According to the method and the device, the display brightness of the f
