Abstract:
An exemplary power supply circuit (200) for a liquid crystal display device (2) includes a switch control circuit (28) for receiving a control signal from an external control circuit, the control signal controlling the turning on or turning off of the switch control circuit; a first DC/DC converter (27) for adjusting the direct current voltage from an external circuit, outputting an output voltage. The switch control circuit controls switches the power supply of the output voltage to a liquid crystal display panel (20) of the liquid crystal display device.
