A sensing device comprises sensor electrodes arranged in an array of rows and columns, and vias. A first vias is arranged in a first direction, and corresponds to a first column of sensor electrodes adjacent to a first side edge of the sensing device. A second via is arranged in a second direction different than the first direction, and corresponds to a second column of the sensor electrodes adjacent to a second side edge of the sensing device. Each of the sensor electrodes is configured to be coupled to a routing trace through one of the vias. In a first row of the plurality of sensor electrodes, a two vias are different distances from the first side edge and in a second row of the plurality of sensor electrodes, two vias are different distances from the second side edge.

Sensor electrode patterns for input devices

Techniques for determining force applied by an input object in a sensing region of an input device are provided. The techniques generally include driving a plurality of sensor electrodes within a sensing region to acquire sensor data, generating a first histogram based on the sensor data, the first histogram including a plurality of bins each having an associated value, and based on the values associated with at least a subset of the plurality of bins of the first histogram, determining force information for an input object.

Estimating force applied by an input object to a touch sensor

Embodiments described herein include an input device, a display device having a capacitive sensing device, a processing system and a method for detecting presence of an input object using a capacitive sensing device. In one embodiment, an input device includes a plurality of sensor electrodes arranged in a planar matrix array. Each sensor electrode is coupled to unique routing trace and has an identical geometric plan form that is symmetrical about a center of area of the sensor electrode. The geometric plan form of each sensor electrode includes core and a plurality of protrusions extending outward from the core. The protrusions are configured to overlap with protrusions extending outward from each adjacent sensor electrode of the matrix array.
