摘要： A data processing system can store a long-term history of pixel luminance values in a secure memory and use those values to create burn-in compensation values that are used to mitigate burn-in effect on a display. The long-term history can be updated over time with new, accumulated pixel luminance values.

摘要： Systems, methods, and non-transitory media are presented that provide for improving color accuracy. An electronic display (12) includes a display region having multiple pixels each having multiple subpixels. The electronic device (10) also includes a display pipeline (36) coupled to the electronic display (12). The display pipeline (36) is configured to receive image data and perform white point compensation on the image data to compensate for a current drop in the display (12) to cause the display (12) to display a target white point when displaying white. The display pipeline (36) also is configured to correct white point overcompensation on the image data to reduce possible oversaturation of non-white pixels using the white point compensation. Finally, the display pipeline (36) is configured to output the compensated and corrected image data to the electronic display (12) to facilitate displaying the compensated and corrected image data on the display region.
