Abstract
The present application provides a mini-LED backlight module, a driving method thereof, and a display device thereof that dispose a plurality of scan line sets. Each of the scan line sets includes a number of M of scan lines. ith ones of the scan lines in the different ones of the scan line sets are connected to one another, and the ith ones of the scan lines in the different ones of the scan line sets are connected to the ith ones of the mini-LED partitions of the backlight groups respectively. Therefore, a number of the source electrode chips is reduced, which drastically decreases a manufacturing cost of the mini-LED backlight module.
