Abstract
An electronic device may include an electronic display having display pixels and pixel drive circuitry that selects an analog voltage for the display pixels based on a first gray-to-voltage mapping and display image data that is based on compensated image data. The electronic display may also include image processing circuitry that receives input image data in a gray level domain, converts the input image data to a voltage domain based on a second gray-to-voltage mapping different from the first, and applies voltage compensations to voltage levels of the input image data in the voltage domain to generate compensated voltage data. The image processing circuitry may also convert the compensated voltage data from the voltage domain to the gray level domain to generate the compensated image data based on a voltage-to-gray mapping that is the inverse of the first gray-to-voltage mapping.
