Light source assembly, method for reducing working current of backlight module and display device

The embodiment of the invention belongs to the technical field of display. The invention provides a light source assembly, a method for reducing the working current of a backlight module and a displaydevice. K light-emitting elements are connected in series to form a lamp string and are connected with the driving circuit of a driving light source assembly through a first light source bonding padand a second light source bonding pad to ensure that when each light source assembly is turned on, the current density in the lamp string is consistent with the current density of a light-emitting chip, so that the effect that the same light-emitting brightness can be emitted by 1/K of the driving current of the light-emitting chips is achieved, the large driving current caused by the fact that the backlight module adopts one light-emitting chip in each subarea is avoided, and the problems caused by the fact that the working current of an existing backlight module is too large are solved. 本发明实施例属于显示技术领域，提供了一种光源组件、降低背光模
