Abstract: Systems, methods, and devices are described that may mitigate display pixel and touch crosstalk noise. A touch processing system may compensate touch scan data to reduce the noise based on a luminance value. An image processing system may determine the luminance value based on image data and a display brightness value of an electronic display. Using the compensated touch scan data, the touch processing system may determine a proximity of a capacitive object to at least one touch sense region of the electronic display.

Abstract: Sensing circuitry of a first electronic device can be configured to sense a signal transmitted by the second, external electronic device contacting and coupling through the body of the user. The first electronic device can be configured to detect the contact while receiving data from the second device, and determine whether the signal transmitted by the external device corresponds an “intentional touch,” or corresponds to a signal coupling between a different body part and the external device or through a different signal pathway (e.g., electromagnetically, through the air, etc.).
