Abstract: 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.

Abstract: 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.
