1. A driving device, adapted to drive at least one light emitting diode (LED), and comprising:

  • a clock recovery unit, for receiving a first alternating current (AC) signal, and generating a square wave signal according to the first alternating current signal;

    a modulation unit, coupled to the clock recovery unit, for receiving the square wave signal and a signal source, and generating a message signal according to the square wave signal and the signal source; and

    a bias tee unit, coupled to the modulation unit, for receiving a second alternating current signal and the message signal, and for outputting a driving signal to the at least one light emitting diode by using the second alternating current signal and the message signal, in order to make the at least one light emitting diode generate an optical signal.
