Abstract:
Embodiments of the present invention generally provide shield electrodes for shielding one or more conductive routing traces from one or more receiver electrodes in an input device comprising a display device integrated with a sensing device to reduce the capacitive coupling between the conductive routing traces and the receiver electrodes. The shield electrode may be configured to reduce the effect of an input object on the capacitive coupling between the conductive routing traces and the receiver electrodes. In other embodiments, end portions of common electrodes shield the receiver electrodes from the conductive routing traces, thereby reducing the capacitive coupling between the receiver electrodes and the conductive routing traces.
