Abstract
An approach for dynamic refresh rate control. For one aspect, a policy, such as a power, performance, quality or other policy, for example, is accessed. A refresh rate may then be dynamically selected in response to detected display content activity and policy preferences for displays that are regularly refreshed. Alternatively, if the display is one of a bi-stable, a self-refreshing display or another type of display that is refreshed irregularly, whether or not to refresh the display may be determined based on detected content activity.
