Zusammenfassung:This document describes systems and techniques for image retention mitigation via voltage biasing for organic light-emitting diode (OLED) displays. In aspects, a pixel array is described having pixel circuits including a first transistor configured to receive a biasing signal from one or more drivers and, based on the biasing signal, enable or disable an application of a bias voltage at a terminal of a second transistor. In so doing, the bias voltage reduces a hysteresis effect experienced by the second transistor for each of the multiple pixel circuits of the pixel array, thereby mitigating an image retention.
