Abstract: Aspects of the subject technology relate to electronic device display circuitry and methods of operating the display. The display circuitry a panel driver interface that decodes digital display data, for each display frame, received from host circuitry of the electronic device. The digital display data includes error correction and detection information for frame and line configuration information distributed in a frame packet and multiple line packets for each display frame. The frame and line configuration information facilitates, efficient, low-error, digital control of various display operational features.

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.
