Abstract
A display system receives first timing information prior to the display system entering a panel self-refresh (PSR) mode. The display system supports a range of refresh rates. Prior to the display system entering the PSR mode, first timing information indicating a first refresh rate that is lower than a maximum refresh rate supported by the display system is received by the display system. The display system then refreshes images at a second refresh rate that is less than or equal to the first refresh rate using a frame stored in a buffer prior to entering the PSR mode. In some cases, the processing unit also receives second timing information from the display system in response to initiating an exit from a panel self-refresh (PSR) mode. The second timing information indicates a current scanout line that is used to schedule transmission of a subsequent frame.
