摘要： LED backlight driver, LED backlight module, and liquid crystal display are disclosed. The LED backlight driver comprises DC voltage input end, boost circuit, LED string, and constant current driver. The DC voltage input end is used for inputting a DC voltage. The boost circuit is used for boosting the DC voltage input from the DC voltage input end and outputting a boosted DC voltage. The LED string comprises a plurality of LEDs connected in series and a first resistor. The LED string receives the boosted DC voltage from the boost circuit. A sum of forward voltages of all of the LEDs in the LED string is less than or equal to the boosted DC voltage output from the boost circuit. The constant current driver is used for outputting a level signal to the boost circuit based on a voltage across the first resistor and a voltage for a triangular signal.
