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.
