Abstract

The embodiment of the invention provides a display screen state control method and apparatus, a storage medium and a terminal. The method comprises the following steps: in a closed state of a signal transmitter, obtaining, by a signal receiver, a first signal; controlling the signal transmitter to send a detection signal, and obtaining, by the signal receiver, a second signal; obtaining a first intermediate signal according to the first signal and the second signal, and converting the first intermediate signal into a digital signal obtain a first digital signal; controlling to close the signaltransmitter and controlling the signal receiver to obtain a third signal; obtaining a second intermediate signal according to the first signal and the third signal, and converting the second intermediate signal into a digital signal obtain a second digital signal; calculating a proximity signal according to the first digital signal and the second digital signal, and controlling the state of a display screen according to the signal strength of the proximity signal. The magnitudes of the first digital signal and the second digital signal are reduced and the accuracy of the data is improved, thereby improving the accuracy of controlling the state of the display screen of the terminal.

Description

Technical field [0001] This application relates to the field of terminal technology, and in particular to a method, device, storage medium, and terminal for controlling the state of a display screen. Background technique [0002] With the rapid development of terminal technology, terminals such as smart phones have become more and more popular and become indispensable devices in people's lives. [0003] Currently, it is a necessary function in the terminal to determine the close or far state between the terminal and the external object to control the screen to turn off or on. The terminal usually uses an infrared transmitter and an infrared receiver to detect the proximity or distance between the terminal and an external object. The infrared transmitter emits infrared light, which forms a reflected light after being reflected by a barrier. After receiving the reflected light, the infrared receiver judges whether the terminal is close to or far from the barrier according to the int...
