Abstract:
Methods and systems for compensating for VCOM variations include determining a voltage change in pixels between frames to be displayed on an electronic display. Based on the determined voltage change, VCOM variation is calculated based on coupling the VCOM to one or more data lines of the electronic display. VCOM compensation is determined and applied to offset for the VCOM variation. Using the VCOM offset, subsequent pixel content for the one or more pixels is written using the compensated VCOM.
