Abstract
A control device for a power switch, a control method for the power switch, and an electronic display system are provided. The control device includes an acoustic sensor and a switch. The switch is coupled between a power supply and an external electronic device. The acoustic sensor senses an acoustic signal. In a standby mode, the acoustic sensor generates a switch control signal according to a frequency of the acoustic signal. The switch turns on or turns off a path for the external electronic device to receive power according to the switch control signal. In the standby mode, the acoustic sensor periodically and actively performs a generating operation of the switch control signal.
