US 2026/0018147 A1 · METHOD FOR REQUESTING VSYNC SIGNAL AND ELECTRONIC DEVICE

Abstract

This application provides a method for requesting a vSync signal and an electronic device, and relates to the field of image display technologies. When a plurality of image frames that are dynamically changing and consecutive need to be displayed, a possibility of freezing and unsmoothness can be reduced. At a first moment, a first application in the electronic device calls a setVsyncRate interface of a window system SF in the electronic device to send a first request to the SF. The first request is for requesting a vSync signal. The SF periodically distributes the vSync signal to the first application in response to the first request. At a second moment, the first application calls the setVsyncRate interface to send a second request to the SF.

Dependent claims

A method for requesting a vSync signal, applied to an electronic device having a display function and having a first application installed thereon, wherein the method comprises:

at a first moment, calling, by the first application in the electronic device, a setVsyncRate interface of a window system SF in the electronic device to send a first request to the SF, wherein the first request is for requesting a vSync signal;
periodically distributing, by the SF, the vSync signal to the first application in response to the first request;
and
at a second moment, calling, by the first application, the setVsyncRate interface to send a second request to the SF, wherein the second request is for requesting to cancel the vSync signal, and after receiving the second request, the SF ends the periodically distributing the vSync signal to the first application.
