1. An input device comprising:

  • a plurality of sensor electrodes disposed in a matrix on a surface of a first layer of a display panel; and

    a processing system coupled to the plurality of sensor electrodes via a plurality of conductive routing traces in a second layer of the display panel, the processing system is configured to;

    acquire a capacitive image frame with the plurality of sensor electrodes based on a pattern such that during a first time period of the pattern a first sensor electrode of the plurality of sensor electrodes is operated in a first mode and a second sensor electrode of the plurality of sensor electrodes is operated in a second mode, and during a second time period of the pattern the first sensor electrode is operated in the second mode and the second sensor electrode is operated in the first mode.
