A method for controlling a screen of a terminal, includes: determining a real-time state of the 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 on a surface of the terminal through a first human body communication component, such that the first electromagnetic signal is transmitted via a skin of a user; receiving, by the first human body communication component via the metal structure, a second electromagnetic signal sent by a wearable device associated with the terminal, the second electromagnetic signal being generated by the wearable device according to the first electromagnetic signal; and if the second electromagnetic signal includes state switching information regarding the screen, switching the real-time state of the screen from the first state to a second state.
