Abstract
An LED backlight driving circuit with a voltage regulating unit is provided. The LED backlight driving circuit includes a power supply unit, an LED string, an ADC voltage detection circuit, and a driving controller; the ADC voltage detection circuit is used to detect a voltage value Vof a negative terminal of a LED string, and the ADC voltage detection circuit includes an ADC sampling module that converts the measured voltage value Vat the negative terminal of the LED string into a voltage numerical code; for the numerical code of the negative terminal voltage value Vmeasured by the ADC sampling module, a first threshold Vand a second threshold Vare set.
