Abstract

The present application provides a method for driving a mini-LED backlight module. The method includes dividing the mini-LED backlight module into a plurality of partitions along an extending direction of a data line, dividing a period of each frame used in the mini-LED backlight module into an adjusting sub-field, and adjusting durations of a bright sub-field or a dark sub-field of the adjusting sub-field corresponding to different partitions based on different gray modes. In such a way, the brightness of each partition falls within a configured brightness threshold range.
