Abstract
The disclosure generally describes input devices with associated processing system configured to perform display updating and capacitive sensing. The processing system includes first and second pluralities of display driver pads coupled with a plurality of source lines, and a plurality of sensor pads disposed between the first and second pluralities of display driver pads and coupled with a plurality of sensor electrodes through a plurality of conductive routing traces. The plurality of sensor electrodes includes at least one common electrode of a display device, the common electrode configured to be driven for display updating and capacitive sensing. The processing system is configured to drive the plurality of source lines for display updating, and to drive the plurality of sensor electrodes for capacitive sensing.
