摘要：
An exemplary liquid crystal display (200) includes a liquid crystal panel (240) having pixel units (248), a scanning circuit (210) configured to activate the pixel units, and a power supply circuit (230) having a control unit (231) and a logic converter (232). 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.
