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.

Abstract: A display may have both a full pixel density region and a pixel removal region with a plurality of high-transmittance areas that overlap an optical sensor. Each high-transmittance area may be devoid of thin-film transistors and other display components. To improve transmission while maintaining satisfactory touch sensing performance, one or more segments of the touch sensor metal in the pixel removal region may have a reduced width relative to the touch sensor metal in the full pixel density region and/or one or more segments of the touch sensor metal in the pixel removal region may be omitted relative to the touch sensor metal in the full pixel density region. To mitigate a different appearance between the pixel removal region and the full pixel density region at off-axis viewing angles, the position of the touch sensor metal in the pixel removal region may be tuned.
