  • Patent number: 9519390
    Abstract: The present invention provides a single electrode layer of a touch panel, which comprises a plurality of electrodes. The electrodes comprise a plurality of holes arranged in a plurality of rows in a first direction and adjacent to one another. The holes are also arranged in a plurality of columns in a second direction and adjacent to one another. The columns of the holes are arranged in a zigzag pattern along the first direction. The rows of the holes are arranged in a zigzag pattern along the second direction. The electrodes are arranged in a zigzag pattern along the first direction corresponding to the holes and forming a first side and a second side opposing to the first side, which are zigzag shape. The first and second sides form a plurality of convex parts and a plurality of concave parts. The geometric shapes of the convex parts and the concave parts extend the zigzag shapes of the holes along the second direction.
