Abstract: A light-emitting diode circuit and a light-emitting diode driving circuit are disclosed. The light-emitting diode driving circuit includes the DC-DC converter and the switch circuit. The DC-DC converter converts a DC voltage to the driving voltage for driving the light-emitting diode. One end of the switch circuit is electrically connected to the DC-DC converters and a cathode of the light-emitting diode, the other end of the circuit switching is electrically connected to a ground terminal. The switch circuit controls the connection between the DC-DC converters, the Light-emitting diodes and the ground terminal based on the control signal.
