The present invention relates to the field of communications. Provided are a terminal screen control method, and a system and terminal. A terminal is provided with at least one magnetic field sensing device therein; if a terminal screen is in a screen-off state and a trigger device is sensed to be adjacent to the terminal, then triggering turning on of the terminal screen; if the terminal screen is in a screen-on state and the trigger device is sensed to be away from the terminal, then triggering locking of the terminal screen. A screen is automatically turned on or locked via sensing whether the trigger device is adjacent to the terminal (a terminal is used) or away from the terminal (the terminal is not used); namely, when a user intends to use the terminal, the screen is automatically turned on without key pressing by the user; when the terminal is not used by a user, the screen is automatically locked without key pressing by the user or waiting for a preset time, thus avoiding waste of electric power; the present invention solves the problem of burdensome operation on currently used terminals and reduces electric power consumption of a terminal to a certain extent, thus providing easier and more convenient operation for a terminal and improving user experiences. |
