Longer battery life is a critically important end user experience for mobile devices such as Ultrabook™. Panel Self Refresh technology allows PSR enabled display to update the images itself thus allowing SoC and link components to be power managed. In addition, power optimized panel designs also help save power while in the PSR mode. This paper overviews mobile PC platform power profile, opportunity and potential for power savings, design considerations of Timing Controller and panel for power optimization and provides a glimpse at the future version of the PSR technology.
