1. A system comprising:
an integrated circuit configured to:
determine a first line-specific common voltage (Vcom) for a first line of pixels of a plurality of lines of pixels of an electronic display by interpolating between a first Vcom of a plurality of common voltages (Vcoms) and a second Vcom of the plurality of Vcoms, wherein the first Vcom is associated with a first row of regions of a plurality of rows of regions of the electronic display, wherein the second Vcom is associated with a second row of regions of the plurality of rows of regions, wherein the first line of pixels is located between the first row of regions and the second row of regions, wherein each respective Vcom of the plurality of Vcoms is associated with a respective row of regions of the plurality of rows of regions of the electronic display, wherein each row of the plurality of rows comprises more than one line of pixels;
determine a second line-specific Vcom for a second line of pixels of the electronic display by interpolating between the second Vcom of the plurality of Vcoms and a third Vcom of the plurality of Vcoms, wherein the second line of pixels is located between the second row of regions and a third row of regions of the plurality of rows of regions, wherein the third Vcom is associated with the third row of regions; and
cause the first line-specific Vcom to be provided to the first line of pixels and the second line-specific Vcom to be provided to the second line of pixels.
