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.

Time-synchronized pixel array and touch array crosstalk mitigation systems and methods

An electronic display may include an ambient light sensor (ALS) located beneath an active area to sense ambient light above the active area. The ALS may have multiple response channels to perform fast sensing integration, which is synchronized with blanking periods of a pixel on the active area. An emission mask and a heat map may be generated for the ALS and used to generate a calibrated heat map for the ALS. The calibrated heat map of the ALS is used with display content to calculate a crosstalk compensation for the ALS.

System for ambient light sensing or compensation

This disclosure provides various techniques for providing fine-grain digital and analog pixel compensation to account for voltage error across an electronic display. By employing a two-dimensional digital compensation and a local analog compensation, a fine-grain and robust pixel compensation scheme may be provided to the electronic display.
