  • Publication number: 20220139015
    Abstract: Video or graphics, received by a render engine within a graphics processing unit, may be segmented into a region of interest such as foreground and a region of less interest such as background. In other embodiments, an object of interest may be segmented from the rest of the depiction in a case of a video game or graphics processing workload. Each of the segmented portions of a frame may themselves make up a separate surface which is sent separately from the render engine to the display engine of a graphics processing unit. In one embodiment, the display engine combines the two surfaces and sends them over a display link to a display panel. The display controller in the display panel displays the combined frame. The combined frame is stored in a buffer and refreshed periodically.
