Abstract
A system and method for mitigating interference within a sensing device. The sensing device may be part of an input device that also includes a display device. The display device may include a display panel having a plurality of display electrodes, and a display driver configured to drive the plurality of display electrodes. The sensing device may include a plurality of sensor electrodes disposed over the display panel, and a sensor driver communicatively coupled to the plurality of sensor electrodes and the display driver. The sensor driver may be configured to acquire sensor data from the plurality of sensor electrodes, receive a display signal from the display driver, and reduce interference within the sensor data at least partially based on the display signal.
