Content-based vcom driving

An electronic device, comprising:

• a display, comprising:
• VCOM compensation circuitry for the display, comprising:
• voltage calculation circuitry configured to:
• calculate VCOM variation coupling the VCOM to one or more data lines of the display;
• determine an offset for VCOM to offset the determined variation;
• VCOM driving circuitry configured to compensate the VCOM voltage using the calculated offset;
• and
• display driving circuitry configured to write pixel content to one or more pixels using the compensated VCOM.

Voltage compensation logic, comprising voltage calculation logic configured to:

• calculate VCOM variation due coupling the VCOM to one or more data lines of the display;
• and
• determine an offset for VCOM to offset the calculated variation;
• and
• VCOM driving logic configured to compensate the VCOM voltage using the calculated offset;
• and
• display driving logic configured to write pixel content to one or more pixels using the compensated VCOM.

One or more non-transitory, computer-readable media having instructions stored thereon that, when executed, are configured to cause a processor to:

• write pixel content of a current line of pixels to a first line buffer;
• write pixel content of a subsequent line of pixels to a second line buffer;
• determine a voltage change between the first line buffer and the second line buffer;
• cause the coupling the VCOM to a data line of the display corresponding to the first line buffer;
• calculate VCOM variation due to the determined voltage change in pixels;
• determine an offset for VCOM to offset the determined variation;
• compensate the VCOM voltage using the calculated offset;
• and
• cause pixel content of the second line buffer to be written the subsequent line of pixels using the compensated VCOM.
