Abstract
In one implementation, a capacitive sensing structure comprises rows of first sensors electrically coupled together and columns of second sensors electrically coupled together, wherein the first sensors include: a first arm extending in a first direction and having a first plurality of finger structures extending therefrom, a second arm extending in the first direction and having a second plurality of finger structures extending therefrom, and an end portion connecting the arms, wherein the first sensors define open regions that are occupied by the second sensors. In a second implementation, a capacitive sensing structure comprises rows of first sensors and columns of second sensors, wherein each of the first sensors includes an elongated portion having finger structures extending therefrom, and wherein each of the second sensors includes a primary portion connected to secondary portions via arms, wherein the secondary portions occupy gaps defined by the finger structures of the first sensors.
