Abstract: Image processing circuitry may include burn-in compensation circuitry that receives image data indicative of luminance outputs for display pixels of an electronic display and compensates the image data for burn-in related aging associated with the display pixels, generating compensated image data. Moreover, compensating the image data may include applying gains based on estimated amounts of aging associated with the display pixels and estimated amounts of current to be delivered to the display pixels. The image processing circuitry may also include burn-in statistics circuitry that tracks the estimated amounts of aging based on the compensated image data.

Abstract: An electronic device may include an electronic display having a pixel and that displays an image based on compensated image data. The electronic device may also include image processing circuitry communicatively coupled to the electronic display. The image processing circuitry may receive image data and determine a gain value for the pixel based on an aging value of the pixel that is based on previously displayed pixel values of the pixel. The image processing circuitry may also adjust the gain value based on a pixel value of the image data corresponding to the pixel to generate an updated gain value and adjust the pixel value of the image data based on the updated gain value to generate, at least in part, the compensated image data.

Abstract: An electronic device may include an electronic display having display pixels that display an image based on compensated image data. The electronic display may also include pixel drive circuitry that provides power to the display pixels in accordance with the compensated image data. Additionally, the electronic device may include burn-in compensation circuitry communicatively coupled to the electronic display that receives input image data and generates the compensated input image data based on the input image data, a pixel aging history corresponding to the display pixels, and a driver aging history corresponding to the pixel drive circuitry.
