A driving circuit for backlight LED comprises a power input, a control module, a voltage promotion module and a filter circuit module. The filter circuit is connected between the power input and the voltage promotion module. The filter circuit module is configured to filter ripple voltage signals from the power source and periodic voltage echo wave signals from the voltage promotion module to eliminate the "water wave" on a LCD display.
