Patent ID: 8797290

Claim:
A device comprising: a plurality of drive electrodes extending in a first direction; a first sense electrode extending in a second direction, the first sense electrode comprising: a first main spine extending in the second direction and adapted to be electrically coupled to control electronics by a first sense line; and a first plurality of interpolation spines extending in the second direction, the first plurality of interpolation spines being electrically coupled to the first main spine by the first sense line, each interpolation spine of the first plurality of interpolation spines overlapping multiple drive electrodes of the plurality of drive electrodes; a second sense electrode extending in the second direction and located adjacent to the first sense electrode, the second sense electrode comprising: a second main spine extending in the second direction and adapted to be electrically coupled to the control electronics by a second sense line; and a second plurality of interpolation spines extending in the second direction, the second plurality of interpolation spines being electrically coupled to the second main spine by the second sense line; wherein: none of the first plurality of interpolation spines of the first sense electrode is located between any one of the second plurality of interpolation spines and the second main spine; and none of the second plurality of interpolation spines of the second sense electrode is located between any one of the first plurality of interpolation spines and the first main spine.
