Abstract: Aspects described herein include a method and associated processing system for a display having a plurality of pixels. The method comprises driving, using display circuitry, a plurality of pixels of a display device to display one or more test patterns. The display device is integrated into a manufactured input device. The method further comprises receiving field-set mura compensation data that is based on one or more images of the plurality of pixels. The one or more images are acquired responsive to displaying the one or more test patterns. The method further comprises writing the field-set mura compensation data to a memory of the input device. The field-set mura compensation data replaces or is stored along with factory-set mura compensation data.

Abstract: A capacitive fingerprint sensor is configured to be integrated in a display. The capacitive fingerprint sensor includes a plurality of transmitter electrodes. Each respective transmitter electrode including at least one transmitter conductor formed in a first metal layer of a sensor stack and disposed between pixels of a display. The capacitive fingerprint sensor further includes a plurality of receiver electrodes. Each respective receiver electrode including at least one receiver conductor formed in a second metal layer of a sensor stack and disposed between pixels of the display. The receiver electrodes have an orientation different from the transmitter electrodes.

Abstract: A method comprises acquiring measured luminance levels at a measurement point of a display area for a plurality of test images displayed in the display area, and estimating one or more luminance levels at one or more corresponding luminance estimation points of the display area using the measured luminance levels. The method further comprises determining, based on the one or more estimated luminance levels, a correction parameter using the estimated one or more luminance levels.
