Abstract: The present disclosure is directed to estimating and modulating peak luminance of the display substantially in real-time to allow very bright pixels to be shown on the electronic display as long as the total electrical energy drawn by the electronic display does not exceed a threshold. The amount of electrical energy that is being drawn by the electronic display may be estimated from the image data by counting the number of rows of pixels that are emitting pulses in discrete bins of time. Because the pulses draw a predictable amount of electrical energy per row per time bin, the amount of electrical energy drawn by the electronic display may be estimated substantially in real time. The image data on the electronic display may therefore be modulated to avoid drawing too much electrical energy from the power source of the electronic device while permitting a high dynamic range.

Abstract: To reduce image artifacts induced by temperature variations associated with display pixels of an electronic display, processing circuitry may process temperature sensing data to obtain an average temperature and a temperature distribution of the electronic display. Based on the processed temperature data, the processing circuit may adjust a reference voltage applied to the display pixels to compensate for the average temperate. To further correct for the image artifacts, the processing circuitry may transform image data to luminance domain. Based on the processed temperature data, the processing may adjust luminance vales of the image data to compensate for the temperature distribution.
