摘要: An electronic device with standby state includes a MCU, a voltage conversion unit, a screen lock circuit, and a power-saving trigger circuit. The voltage conversion unit is connected to the MCU and is used to convert a power supply voltage to a suitable voltage to power the MCU. The screen lock circuit includes a switch, therein, the screen lock circuit is connected to the MCU and is used to lock or unlock the electronic device in response to an operation on the switch when the electronic device is in a work state. The power-saving trigger circuit is connected to the MCU, the voltage conversion unit, and the screen lock circuit, and is used to disable or enable the voltage conversion unit in response to the operation on the switch when the electronic device is in the standby state.

摘要: A power management circuit comprising a power-on signal input, an output terminal a control unit, a switching unit, and a discharge unit. The control unit configured to selectively turn on the switching unit to output a power-on signal to a display module and selectively turn off the switching unit to cut off an electrical connection between the power-on signal input and the output terminal. The discharge unit configured to discharge residual electrical charges in the display module when the switching unit is turned off.
