Title:
SCREEN DISPLAY CONTROL METHOD, AND MEDIUM AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/037460
Kind Code:
A1
Abstract:
The present application relates to the technical field of electronics. Disclosed are a screen display control method, and a medium and an electronic device. The method comprises: transmitting an ultrasonic signal; acquiring a plurality of echo signals, which are received within a first time period and are generated after the ultrasonic signal is reflected by objects; when there is a user who moves relative to an electronic device among the objects that reflect the ultrasonic signal, executing a first screen display mode if the plurality of echo signals meet a first condition for indicating whether the user is present; and when there is not a user who moves relative to the electronic device among the objects that reflect the ultrasonic signal, executing a second screen display mode if the plurality of echo signals do not meet the first condition for indicating whether the user is present. On this basis, an electronic device can correspond to different screen display modes according to whether there is a user in front of the electronic device, such that the user experience is improved, thereby avoiding power consumption waste caused by a normally open screen when there is no user in front of the electronic device.
