Abstract

This application discloses a frame sending and display time anchoring method, an electronic device, and a storage medium, and relates to the field of terminal technologies. The method includes: When it is detected that a jump occurs in a VSYNC signal, a terminal device first calculates an expected sending and display time of a target frame through an SF; then determines whether the target frame is a first frame and whether a current time is less than an earliest sending and display time; if yes, sends the expected sending and display time to an HWC in a HAL layer; then calculates, based on the expected sending and display time and a period of the VSYNC signal, a time period in which the HWC needs to suspend sending and display; and then controls, based on the time period in which the HWC needs to suspend sending and display, the HWC to perform a sleep operation until an incorrect sending and display time is missed, and when the expected sending and display time is reached, performs an operation of sending and displaying the target frame on a screen. In this way, the expected sending and display time is packaged only for the first frame, and is transmitted to the HWC to anchor the sending and display time. This can reduce anchoring costs, shorten a parameter transmission path, and improve maintainability of the anchoring method.
