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 an active array and a reference array. The active array includes a pixel and the reference array includes a reference pixel. The electronic device also includes processing circuitry communicatively coupled to the display. The processing circuitry is configured to instruct the active array to drive the pixel based at least in part on a set of degradation ratios and gamma tap points for each brightness setting of the display based at least in part on a reconstructed current-voltage curve.
