Abstract
An intelligent adjustment method and system for an LED backlight drive, a device and a storage medium are disclosed. The method includes: acquiring optimized channel current on each of other LED substring branches other than a non-maximum conduction branch; calculating, according to the optimized channel current, the number of cycles of conducting PWM of each LED substring branch in one frame of a frame synchronizing signal as the number of cycles of the optimized conducting PWM; and adjusting a channel current of each LED substring branch to be a corresponding optimized channel current, and adjusting the number of cycles of a conducting PWM of each LED substring branch to be the number of cycles of the optimized conducting PWM.
