Abstract
The present application provides a backlight module and a display device. The backlight module includes multiple light-emitting units, at least one driving chip, and an adjustment module. In the driving chip, control units are used to control the respective corresponding light-emitting unit to emit light based on control signals. Each control unit has a feedback node. A signal acquisition unit is connected to the feedback nodes to collect feedback voltages of the feedback nodes. An adjustment module is connected to the at least one driving chip and is used to adjust light-emission brightness of the light-emitting units according to the feedback voltages.
