POWER EFFICIENT ADAPTIVE PANEL PIXEL CHARGE SCHEME
Abstract:
This application relates to systems, methods, and apparatus for reducing the power consumption of a display panel. Specifically, the embodiments discussed herein relate to a panel pixel charge scheme that allows the current output of a display driver to be modified based on the content to be displayed at the display panel. The display driver can compare current and upcoming display content in order to determine how the line voltage for one or more output lines will change over time. If, based on the comparison, the voltage for an output line is not going to vary substantially over time, the bias current output from the display driver can be modified in order to save power. The modification to the bias current can depend on the amount of change the line voltage will undergo in subsequent executions of the content data.
