Abstract:
An electronic device may include a display panel to display an image and a display pipeline to process image data for the image. The display pipeline may include a controller to determine a first potential presentation time based on a maximum refresh rate of the display panel. The controller may also determine if a second target presentation time of a second image is equal to the first potential presentation time before a pipeline configuration time, and if the second target presentation time of the second image is equal to a second potential presentation time that occurs after the first potential presentation time and before a first pre-notification time occurring before the pipeline configuration time. The controller may output a first pre-notification signal at the first pre-notification time that instructs the display panel to pause self-refreshes until after the second image is displayed.
