Abstract
A method of adjusting a test gray voltages applied to a component of an electronic display during a test frame between image frames, wherein the adjustment is based at least in part on the control signal to the component during a prior image frame. The method may reduce hysteresis effects on the extraction of sensed currents of the component during the test frame, which may increase the accuracy and/or consistency of determined parameters evaluated from the sensed currents. The determined parameters may include temperature and/or aging of the component. The determined parameters may be used to adjust control signals for the component and other components in a region near the component during the next image frame.
