Abstract:
This application relates to systems, methods, and apparatus for optimizing the operations of a power converter of a display panel based on image data to be output by the display panel. The power converter can include one or more switches that can be activated or deactivated based on the image data in order to shift a power efficiency of the power converter. Power efficiency is shifted as a result of balancing an amount of charge necessary for a load with an amount of resistance created when activating switches of the power converter. Therefore, by dynamically altering a configuration of a power converter based on image data, power efficiency of the power converter can be improved.
