Frame sending and displaying time anchoring method, electronic equipment and storage medium

Abstract

The invention discloses a frame sending and displaying time anchoring method, electronic equipment and a storage medium, and relates to the technical field of terminals. The method comprises the following steps: when detecting that a VSYNC signal jumps, terminal equipment firstly calculates the expected sending and displaying time of a target frame through SF, then judges whether the target frame is the first frame and judges whether the current time is shorter than the earliest sending and displaying time, if so, sends the expected sending and displaying time to an HWC of an HAL layer, and then sends the expected sending and displaying time to the HWC of the HAL layer according to the expected sending and displaying time and the period of the VSYNC signal; the method comprises the following steps: calculating a time period when the HWC needs to pause transmission display, controlling the HWC to carry out dormancy operation according to the time period when the HWC needs to pause transmission display until wrong transmission display time is missed, and when the expected transmission display time is reached, carrying out the operation of transmitting and displaying a target frame to a screen. In the embodiment of the invention, the expected transmit-display time is only packaged at the first frame and transmitted to the HWC to anchor the transmit-display time, so that the anchoring cost can be reduced, the parameter transmission path can be shortened, and the maintainability of the anchoring method can be improved.
