Abstract
A touch panel includes a substrate and a first electrode array. The first electrode array is disposed on the substrate and includes first and second touch regions. The first electrode array further includes first, second, third, and fourth electrodes. The first electrode is disposed on the first touch region. The second electrode is disposed on the first touch region corresponding in position to the first electrode. The third electrode is disposed on the second touch region. The fourth electrode is disposed on the second touch region corresponding in position to the third electrode. In addition, the first to fourth electrodes are all disposed on the same layer. The first electrode is disposed diagonally to the fourth electrode, and the first electrode is electrically coupled to the fourth electrode. Furthermore, a method for controlling the touch panel is also disclosed herein.
