1. An electronic device comprising:
an electronic display comprising a plurality of display pixels; and
processing circuitry configured to generate image data for the plurality of display pixels, wherein the processing circuitry is configured to:
receive a current frame value of the image data targeted for a first display pixel of the plurality of display pixels; and
based on the current frame value and a pixel history of the first display pixel indicating a plurality of previous frames, determine a modified pixel value with a remapping function, and generate a compensated value used to drive the first display pixel to overcome pixel hysteresis due to the first display pixel being previously driven for the plurality of previous frames.
