Abstract:
A capacitive touch panel that improves detection of non-conductive objects includes a substrate; a first drive line; a first and second sense line disposed on the substrate; a first plurality of electrode elements, each electrode element of the first plurality of electrode elements is coupled to the first drive line, and the first plurality of electrode elements includes a first drive element; a second plurality of electrode elements, each electrode element of the second plurality of electrode elements is coupled to the first sense line, and the second plurality of electrode elements includes a first sense element disposed adjacent to the drive element; and a third plurality of electrode, each electrode element of the third plurality of electrode elements is coupled to the second sense line, and the third plurality of sensor elements includes a second sense element disposed in a nearest neighbor position relative to the first drive element.
