Abstract
A device may include an electronic display to display an image frame based on image data. The electronic display may include an illuminator that generates light, multiple light regulators that control emission of the light pixel locations on the electronic display based on bitplane data, and driving circuitry that applies an operating electrical stimulus to the illuminator during an emission period of the image frame and a reference electrical stimulus to the illuminator during an off period of the image frame. While the reference electrical stimulus is applied the bitplane data may be indicative of off bitplane. Additionally, the electronic display may include measurement circuitry that measures a response characteristic of the illuminator in response to the reference electrical stimulus and generates temperature data indicative of the temperature of the illuminator based on the response characteristic.
