摘要： A back light unit comprising a light source and a transformer is provided. The transformer has a first side and a second side. The first side is used to receive a pulse width modulation (PWM) signal. More specifically, the second side has a first terminal, a measurement terminal and a second terminal. The first terminal is grounded so that a first inductance is formed between the measurement terminal and the first terminal and a second inductance is formed between the second terminal and the first terminal. In addition, the measurement terminal outputs a measurement voltage to represent a work characteristic parameter and the second terminal outputs a driving signal to drive the light source.
