Abstract
Systems, methods, and devices are provided for mitigating visual artifacts by dynamically tuning bias voltages applied to display pixels. An electronic display may include a display pixel and a bias voltage supply. The bias voltage supply may supply a first bias voltage to the display pixel for a first subframe of a frame of image data. The bias voltage supply may supply a different second bias voltage to the display pixel for a second subframe of the frame of image data. This may mitigate certain image artifacts, such as flicker or variable refresh rate luminance difference, that could arise due to display pixel hysteresis that varies across subframes of the image frame.
