Source-side synchronization of frame updates for displays

A non-transitory computer-readable medium configured to store instructions that, if executed by one or more processors, cause an apparatus to:

• determine a number of elapsed emission cycles since a previously provided frame based on an elapsed time since the previously provided frame and an emission cycle frequency of a display;
• determine a number of emission cycles per frame based on the emission cycle frequency and a frame rate of the display;
• determine a time delay based on the number of emission cycles elapsed and the number of emission cycles per frame;
• and
• provide, based on the time delay, a next frame to the display to align the next frame with an emission cycle boundary of the display.

An apparatus comprising:

• one or more processors configured to:
• determine a number of elapsed emission cycles since a previously provided frame based on an elapsed time since the previously provided frame and an emission cycle frequency of a display;
• determine a number of emission cycles per frame based on the emission cycle frequency and a frame rate of the display;
• determine a time delay based on the number of elapsed emission cycles, the number of emission cycles per frame, and whether the number of elapsed emission cycles aligns with an emission cycle boundary;
• and
• provide, based on the time delay, a next frame to the display to align the next frame with a next emission cycle boundary of the display.
