Abstract

A method for switching a screen state, a terminal, and computer-readable medium are provided. The method includes: transmitting a transmission sound wave when it is detected that the screen state of the terminal is in a light-on state during a voice communication session, the transmission sound wave being a sound wave of a pre-defined frequency; determining a target detection region when a target receiving sound wave is received through a plurality of pre-installed sound wave receiving devices, the target receiving sound wave being formed by reflecting the transmission sound wave by a target object; and switching the screen state of the terminal from the light-on state into a light-off state when it is determined that the target object is located in the target detection region.
