Abstract:
1. A method for controlling a screen of a terminal, comprising: during a calling process or a call originating process of the terminal, determining whether a distance between a specified area of the screen and a human body is larger than a distance threshold value based on an electrical signal generated by the screen when the specified area of the screen gets close to the human body; controlling the screen to be off if it is determined that the distance is not larger than the distance threshold value, and controlling the screen to be on if it is determined that the distance is larger than the distance threshold value; wherein determining whether the distance between the specified area and the human body is larger than the distance threshold value comprises: detecting a current value of a supplemental current of a contact capacitance generated by the screen when the specified area of the screen gets close to the human body; determining that the distance between the specified area and the human body is not larger than the distance threshold value when the current value is not less than the current threshold value; and determining that the distance between the specified area and the human body is larger than the distance threshold value when the current value is less than the current threshold value.
