1. A device comprising an electronic display configured to display an image frame based on image data, wherein the electronic display comprises:
an illuminator configured to generate a light;
a plurality of light regulators configured to control emission of the light at a plurality of pixel locations of the electronic display based on bitplane data;
driving circuitry configured to apply an operating electrical stimulus to the illuminator during an emission period of the image frame and a reference electrical stimulus during an off period of the image frame, wherein the bitplane data comprises an off bitplane while the reference electrical stimulus is applied; and
measurement circuitry configured to measure a response characteristic of the illuminator in response to the reference electrical stimulus.
