Abstract: A backlight module is provided, and includes: a plurality of LED strings, each of which is formed from a plurality of LEDs connected in series and has an LED string current flowing through it, and a dimming controller which controls the duty cycle of a voltage pulse wave supplied to each of the LED strings, wherein the LED string current of each of the LED strings multiplied by the duty cycle of the voltage pulse wave for the same LED string equals a value, and the error between the values of the LED strings is within 6% of any of the values.
