State control method and device for terminal screen, and electronic equipment

The present disclosure relates to a state control method and device for a terminal screen, and electronic equipment. A terminal comprises a first human body communication assembly connected to a metal structure arranged on the surface of the terminal. The method comprises: determining a real-time state of a terminal screen as a first state; generating a first electromagnetic signal corresponding to the first state, and sending the first electromagnetic signal to a metal structure through a first human body communication assembly so that the first electromagnetic signal can be transmitted through the skin of a user; receiving a second electromagnetic signal returned by an associated wearable device according to the first electromagnetic signal; and when the second electromagnetic signal contains state switching information aiming at the terminal screen, switching the real-time state from the first state to a second state. The technical solution of the present disclosure can fast switch and control a locking state of the terminal screen and can facilitate improvement of safety and reduction of power consumption.
