Embodiment Construction

[0025] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0026] With the popularity of the full-screen design of mobile terminals, in order to save the top space of mobile terminals, more and more manufacturers have adopted ultrasonic proximity detection solutions on mobile terminals to replace traditional infrared proximity detection solutions. The mobile terminal emits ultrasonic waves through the ultrasonic wave sending device (such as earpiece, speaker, special ultrasonic transmitter, etc.), and part of the ultrasonic wave propagates through the air to the ultrasonic receiving device (pickup) (such as figure 1 Path 1), a part of the ultrasonic wave propagates through the air and is reflected by obstacles before reaching th...

Abstract

The application discloses a screen state control method, device, mobile terminal and storage medium. When the mobile terminal is in a call state, send an ultrasonic signal through the ultrasonic sending device, and receive the ultrasonic signal returned by the ultrasonic signal after encountering an obstacle through the ultrasonic receiving device, obtain the attribute value of the ultrasonic signal during transmission, and based on the attribute value Calculate the Doppler effect area difference and the Doppler effect area sum of the ultrasonic signal during transmission, and judge the relative motion state between the mobile terminal and the obstacle according to the Doppler effect area difference and the Doppler effect area sum. The motion state controls whether the display screen is on or off. The present application calculates the Doppler effect area difference and the Doppler effect area during the transmission process of the ultrasonic signal and controls the display screen to be in the bright screen state or the off screen state to improve the accuracy of detection and control.

Description

technical field [0001] The present application relates to the technical field of mobile terminals, and more specifically, to a screen state control method, device, mobile terminal and storage medium. Background technique [0002] With the popularity of the full-screen design of mobile terminals, in order to save the top space of mobile terminals, more manufacturers have adopted ultrasonic proximity detection solutions on mobile terminals to replace traditional infrared proximity detection solutions. However, at present, the anti-interference ability of the proximity detection through the ultrasonic detection scheme is poor, so when there is some ultrasonic noise interference in the environment, the detection result will have a large error. Contents of the invention [0003] In view of the above problems, the present application proposes a screen state control method, device, mobile terminal and storage medium to solve the above problems. [0004] In the first aspect, the ...
