Abstract
An electronic device may include an electronic display panel having multiple display pixels for displaying an image based on analog voltage signals. The electronic device may also include interpolation circuitry to generate the analog voltage signals based on digital image data corresponding to the image. The interpolation circuitry may also receive analog reference voltages and interpolate between sets of the analog reference voltages to generate intermediate voltages, which may be a part of the analog voltage signals. Interpolating between the sets analog reference voltages may include performing a first level interpolation of a first set of the analog reference voltages to generate a first intermediate voltage and performing a second level interpolation of a second set of the analog reference voltages to generate a second intermediate voltage, wherein the first level interpolation is different from the second level interpolation.
