Abstract

A processing system for a transcapacitive sensing device comprises a plurality of sensor electrodes sectioned by a seam, a first sensor electrode integrated circuit, and a second sensor electrode integrated circuit. The plurality of sensor electrodes comprises a plurality of transmitter electrodes intersecting a plurality of receiver electrodes. The first sensor electrode integrated circuit is communicatively coupled to a first subset of the plurality of sensor electrodes. The second sensor electrode integrated circuit is communicatively coupled to a second subset of the plurality of sensor electrodes. The first sensor electrode integrated circuit and the second sensor electrode integrated circuit are configured to operate the plurality of sensor electrodes in synchrony to transmit with the plurality of transmitter electrodes a set of transmitter signals and receive with the plurality of receiver electrodes a set of responses corresponding to the set of transmitter signals.
