Abstract: An electronic device may include an electronic display having multiple display pixels. The display pixels may illuminate at a target luminance based at least in part on a first analog voltage signal. The electronic device may also include an electrical bus configured to generate multiple analog voltage signals including the first analog voltage signal, which is output on an output of the electrical bus. The electrical bus may include a digital to analog converter to generate at least some of the analog voltage signals and multiple output buffers to buffer the analog voltage signals. The outputs may be buffered by an output buffer of the output buffers.

Abstract: An electronic device includes a display having a number of pixels, source driving circuitry that drives data to the pixels, and data lines that communicatively couple the source driving circuitry with the pixels. The electronic device also includes quality monitoring and calibration circuitry that identifies degradation in the source driving circuitry, one or more of the data lines, or both. The electronic device may be controlled based at least in part upon identification of the degradation.

Abstract: A mobile electronic device includes a display having a pixel and processing circuitry separate from but communicatively coupled to the display. The processing circuitry prepares image data to send to the pixel and adjusts the image data to compensate for operational variations of the display based on feedback received from the display that describes a present operational behavior of the pixel. The mobile electronic device also includes additional electronic components that affect the present operational behavior of the pixel depending on present operational behavior of the additional electronic components.
