Problems solved by technology

[0004] However, the above-mentioned conversion of the received infrared light signal into an infrared light intensity value is very unstable. Even when there is no occluder close to the screen of the mobile terminal, the reported infrared light intensity value will still jump, especially under sunlight. The jump in the infrared light intensity value is particularly strong
The continuously changing infrared light intensity value may cause the screen of the mobile terminal to flicker

Abstract

The invention discloses a screen on-off control method, a screen on-off control device and a mobile terminal. The method comprises the following steps: collecting infrared light intensity values at a preset frequency; getting an Nth infrared light intensity value and M infrared light intensity values before the Nth infrared light intensity value, wherein N is greater than M, and N and M are positive integers; calculating the Nth infrared light intensity reported value according to the Nth infrared light intensity value and the M infrared light intensity values before the Nth infrared light intensity value; getting the state of the screen of a mobile terminal; and when the screen is off, lighting up the screen under control according to the Nth infrared light intensity reported value and a first preset threshold. Through the method, the change of infrared light intensity value is relatively gentle, a splash screen is avoided for the mobile terminal, and the user experience is enhanced.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a method and device for controlling screen on and off, and a mobile terminal. Background technique [0002] At present, mobile terminals (such as smart phones) use proximity sensors to detect whether the shield is too close to the screen, for example, when the user is making a call, whether the face is too close to the screen of the mobile terminal, when it is detected that the user's face is too close to the screen , in order to avoid misoperation of the face on the mobile terminal, control the screen of the mobile terminal to turn off. [0003] Among them, the receiving end of the proximity sensor performs analog-to-digital conversion according to the received infrared light, and converts the infrared light into an infrared light intensity value for reporting. When there is no blocking object approaching, the infrared light intensity value calculated by the rec...
