Driving circuit, backlight module and driving method therefor, and display apparatus

Abstract

The present disclosure provides a driving circuit, a backlight module and a driving method therefor, and a display apparatus. The driving circuit includes a driving transistor and a voltage adjusting circuit; a source of the driving transistor is coupled to a first voltage signal end, a drain of the driving transistor is coupled to a light-emitting device group, and a gate of the driving transistor is coupled to an output terminal of the voltage adjusting circuit, where the light-emitting device group includes a plurality of light-emitting regions arranged in a first direction, and each light-emitting region includes at least one light-emitting device; a first input terminal of the voltage adjusting circuit is coupled to a second voltage signal end; the voltage of the second voltage signal end is a preset driving voltage Vgs of the driving transistor.
