This invention provides a dynamic control method for LED backlight module, in which each LED of a backlight module is connected with respective parallel circuit, and each parallel circuit is connected in series together. Then, only a single current source is used to supply the required power for light emitting of the whole LEDs series, and the brightness of each LED is controlled by controlling the current flowing through each LED with the parallel circuit according to flow dividing method. In this manner, the connection in the whole circuit design and its control become easier and simpler.
