Enhanced smoothness digital-to-analog converter interpolation systems and methods

An electronic device comprising:

• an electronic display panel comprising a plurality of display pixels configured to display an image based at least in part on a plurality of analog voltage signals;
• and
• interpolation circuitry configured to generate the plurality of analog voltage signals based at least in part on digital image data corresponding to the image, wherein the interpolation circuitry is configured to:
• receive a plurality of analog reference voltages;
• and
• interpolate between sets of the plurality of analog reference voltages to generate a plurality of intermediate voltages, wherein the plurality of analog voltage signals comprises the plurality of intermediate voltages, wherein interpolating between the sets of the plurality of analog reference voltages comprises performing a first level interpolation of a first set of the plurality of analog reference voltages to generate a first intermediate voltage of the plurality of intermediate voltages and performing a second level interpolation of a second set of the plurality of analog reference voltages to generate a second intermediate voltage of the plurality of intermediate voltages, wherein the first level interpolation is different from the second level interpolation.
