Systems and methods for low power common electrode voltage generation for displays

A display system for displaying an image comprising:

• a display panel having a plurality of pixels, each of the plurality of pixels having a pixel electrode voltage, and a common electrode voltage;
• and
• a digital drive device coupled to the display panel comprising:
• a bit plane memory storing values for providing the pixel electrode voltage to each of the plurality of pixels;
• a common electrode circuit coupled to the display panel for providing the common electrode voltage;
• and
• at least one first amplifier coupled to the display panel configured to generate a maximum pixel voltage and a minimum pixel voltage;
• wherein the pixel electrode voltage switches from the maximum pixel voltage to the minimum pixel voltage according to a voltage received by at least one of the plurality of pixels from the bit plane memory,
• wherein the common electrode circuit further comprises at least one second amplifier configured to generate a predetermined voltage, and
• wherein a value of the common electrode voltage switches between the minimum pixel voltage minus the predetermined voltage and switches between the maximum pixel voltage plus the predetermined voltage.
