摘要： A current-controlling apparatus is suitable for controlling the current passing through a light emitting device string (LEDS), wherein an end of the LEDS is electrically connected to a first-voltage level. The current-controlling apparatus includes a current-adjusting unit and a control unit. The current-adjusting unit, electrically connected between a second-voltage level and another end of the LEDS, is used for detecting a current of the LEDS, producing a feedback signal hereby and controlling the impedance between the LEDS and the second voltage level according to a conductance-controlling signal and an impedance-controlling signal to control the current. The control unit is electrically connected to the current-adjusting unit for receiving a reference signal and the feedback signal, comparing the feedback signal with the reference signal to give a comparison result, performing a current compensation on the comparison result and converting the compensated comparison result into the conductance-controlling signal and the impedance-controlling signal.
