    Abstract: A capacitive touch sensitive apparatus comprises plurality of electrodes disposed within a touch sensitive viewing area. Spaced part electrically conductive first electrodes extend along a first direction and spaced apart electrically conductive second electrodes extend along a different second direction. Electrically isolated electrically conductive first polygonal islands are disposed between each pair of adjacent first electrodes and electrically isolated electrically conductive second polygonal islands are disposed between each pair of adjacent second electrodes. When viewed from a top plan view and except for a plurality of discrete spaced part open regions, the touch sensitive viewing area is covered by at least one of a first electrode, a second electrode, a first island, and a second island, each open region being at a vertex of at least one of the first and second polygonal islands.

    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.
