Abstract:
Systems, apparatuses, and methods for adjusting the frame refresh rate used for driving frames to a display. A display pipeline is configured to drive a display using a reduced frame refresh rate in certain scenarios. The reduced frame refresh rate may be specified in frame packets which contain configuration data for processing corresponding frames. The display pipeline may drive idle frames to the display to generate the reduced frame refresh rate. When a touch event is detected, the display pipeline may override the reduced frame refresh rate and instead utilize a standard frame refresh rate until all of the frames corresponding to stored frame packets have been processed.
