LED DRIVE SYSTEM AND ELECTRONIC DEVICE

The present application provides an LED drive system and an electronic device. The LED drive system comprises an LED circuit board; the LED circuit board comprises an LED drive and an LED; the LED drive comprises a control circuit and a switching circuit; the switching circuit is used for controlling the brightness of the LED; the control circuit is connected to a control end of the switching circuit for controlling the connection/disconnection of the switching circuit; and the other ends of the switching circuit other than the control end are all arranged separately from a ground end of the control circuit inside the LED drive. The LED drive system and the electronic device provided by the present application can reduce the influence of a large current of the LED on the ground end of the control circuit, and ground bounce of an LED loop does not interfere with the voltage of the control circuit as much as possible, thereby reducing a circuit failure caused by the ground bounce, and improving the device opera
