US Patent 9715304 Regular via pattern for sensor-based input device

This disclosure generally describes an input device, a display device having an integrated capacitive sensing device, and an assembly for an input device. The input device comprises a plurality of sensor electrodes disposed in a first layer, and a processing system configured to detect presence of input objects in a sensing region defined proximate to the plurality of sensor electrodes. The input device further comprises a plurality of routing traces disposed in a second layer and coupled with the processing system, and a plurality of vias arranged in a regular pattern within an areal extent of the sensing region, wherein at least a portion of the plurality of vias couple the plurality of sensor electrodes with the plurality of routing traces.
