摘要:
A luminance control circuit including a detection unit, a control unit and a current adjustor is provided. The detection unit detects a working current of each light emitting module and produces detection signals to be transmitted to the control unit. The control unit produces control signals according to the detection signals to be transmitted to the current adjustor. The current adjustor adjusts each of the working currents of each of the light emitting modules according to the control signals.
