Abstract: A backlight constant current control circuit and a backlight structure are disclosed. The backlight constant current control circuit and the backlight structure include a light-emitting module and a constant current control module. The constant current control module includes a feedback unit connected to an output end of the light-emitting module and a voltage regulating unit connected to an input end of the light-emitting module. When a working current of the light-emitting module deviates from a preset current, the feedback unit outputs a voltage regulation signal to the voltage regulating unit, and the voltage regulating unit adjusts a voltage of the input end of the light-emitting module according to the voltage regulation signal to make the working current the preset current.
