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.
