The embodiment of the invention provides a driving method of a mini LED backlight module and a display device. Comprising a backlight module and a control module, the backlight module comprises a plurality of light-emitting elements, a light-emitting area is divided into a plurality of different sub-light-emitting areas during driving, each sub-light-emitting area forms a new regulation and control area, and each sub-light-emitting area comprises at least two light-emitting elements; when the backlight module needs to emit light, a brightness control signal corresponding to the control module is adjusted, different light-emitting elements in the sub-light-emitting areas select corresponding bit values according to the brightness control signal and then combine the bit values, and when the backlight module needs to emit light, one group is selected from the different combinations and emits light according to the bit values in the group. The brightness control signal of the control module is adjusted, so that t
