Abstract
An electronic device may include an electronic display having multiple display pixels to display an image based on analog voltage signals. The electronic device may also include optical calibration circuitry to generate digital-to-analog converter (DAC) data based on image data associated with the image and dither circuitry to reduce a bit-depth of the DAC data, generating dithered DAC data. Additionally, the electronic device may include a gamma generator having one or more DACs to generate the analog voltage signals based on the dithered DAC data, which may instruct the gamma generator to generate the analog voltage signals indicative of the image data.
