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.
A method for providing a data line output from a display driver of a display device having a display panel, the method comprising:
A system for reducing power consumption of a display device having a display panel, based on content data to be displayed with the display panel of the display device, the system comprising:
A display driver directly coupled to a plurality of data lines of a display panel and configured to reduce power consumption by the display panel having at least a first row line and a second row line, based on content data to be displayed by the display panel, the display driver comprising:
