Abstract
Disclosed is a method, a system, a device, an apparatus and a medium for driving an LED display screen. When the total grayscale value of an LED lamp bead is greater than a grayscale threshold value, the sub-grayscale value of the LED lamp bead is determined based on a total grayscale value of the LED lamp bead, a total number of sub-frames and a grayscale growth sequence number of each sub-frame image, otherwise, the sub-grayscale value of the LED lamp bead is determined according to the total grayscale value of the LED lamp bead, the grayscale non-dispersion threshold value and the grayscale growth sequence number of each sub-frame image; according to the sub-grayscale value of each LED lamp bead in each sub-frame image, the LED display screen is driven to display each sub-frame image, so that the grayscale value can be uniformly dispersed, and image display quality is improved.
