Abstract
An exemplary liquid crystal display () includes a liquid crystal panel () having pixel units (), a scanning circuit () configured to activate the pixel units, and a power supply circuit () having a control unit () and a logic converter (). The control unit generates a control signal when an external command is applied to the power supply circuit. The logic converter carries out a predetermined logic calculation between the control signal and the external command. The scanning circuit activates all the pixel units to discharge in response to a result of the logic calculation, such that an image displayed by the liquid crystal panel is removed.
