Abstract
Embodiments disclosed herein provide systems and methods for testing and compensating for pixel degradation in an electronic display based on current and voltage values sensed in a reference array. An electronic display includes an active array, a reference array, and sensing circuitry. A compensation manager obtains current data values of the reference array from the sensing circuitry. The compensation manager generates a current-voltage curve based on the current data and adjusts the current-voltage curve to compensate for variations in temperature and/or pixel brightness. In this way, the compensation manager may improve performance of the electronic display by, for example, by reducing visible anomalies.
