Abstract
An exemplary power supply control circuit () includes a first port (), a second port (), a third port (), a controllable switch (), and a control circuit (). The first and second ports are configured to receive a power supply voltage signal. The second and third ports are configured to output the power supply voltage signal to a load circuit. The controllable switch includes a control member () and a switch member (). The control circuit is configured to control a working state of the control member. When the load circuit stops working, the control circuit controls the control member to control the switch member to be disconnected, so as to cut off the power supply voltage signal from outputting to the load circuit. A liquid crystal display () using the power supply control circuit is also provided.
