  • Patent number: 11990082
    Abstract: The present disclosure provides methods and apparatus for configuring an image data transfer time for sending image data from a processor to a display panel along a display path. One method includes receiving, by the processor from the display panel, a display panel refresh interval indication indicating a display panel refresh interval of the display panel. The display panel refresh interval of the display panel corresponds to a time duration of a display period of the display panel. The display panel is configured to refresh each display period. The image data transfer time is computed based on the display panel refresh interval. One or more components of the display path are configured to support the computed image data transfer time.

  • Publication number: 20230334746
    Abstract: High frames-per-second (FPS) displays are becoming more ubiquitous in devices such as smartphones, laptops, etc. For displaying data on displays, render sync signal and compose sync signal control timings of rendering and composing. Conventionally, there is one render sync signal and one compose sync signal for a display, and both share the same frequency as the HW sync signal of the display hardware. As the FPS of the display becomes faster and faster, i.e., as HW sync signal frequency increases, some application layers may be unable to render fast enough to keep up with the increased frequency. To address this issue, it is proposed to provide multiple render sync signals of differing frequencies and phases, and different render sync signals may be used to control the timings of rendering of different application layers. Through such managing of the application layer rendering, a better user experience can be provided.
