Abstract: A capacitive touch sensor includes a touch sensitive viewing area with a border area surrounding the touch sensitive viewing area and having an outermost polygonal perimeter comprising a plurality of sides and vertices. A plurality of spaced apart electrically conductive first electrodes is disposed in the touch sensitive viewing area and extends along a first direction. A plurality of spaced apart electrically conductive second electrodes is disposed in the touch sensitive viewing area and extends along a different second direction. Electrically conductive bus lines are disposed in the border area for electrically coupling the pluralities of the first and second electrodes to a controller. At least one first alignment feature is disposed within the border area near each of at least three vertices of the polygonal perimeter for aligning the touch sensor to a substrate. At least one second alignment feature is disposed within the border area near at least one side of the polygonal perimeter and away from the vertices corresponding to the side.
