ABSTRACT:
Systems and methods for reducing the power consumption necessary for updating a display are provided. The methods include determining a row addressing order based on an attribute of the image data that minimizes the number of column charging transitions necessary to write the image data to the display. In some embodiments, the row-addressing order is determined based on a determination of a whiteness value for the row. In some embodiments, a power-optimized row-addressing order is embedded in image data, allowing a display device to write the image data to the display more efficiently.
