Abstract
A free form touch device includes a substrate, a first switching device, a first touch electrode, a second switching device, and a second touch electrode. The first switching device includes a first channel layer, a first gate, a first source, and a first drain. An overlapping width of the first gate and the first channel layer is W, and an overlapping length of the first gate and the first channel layer is L. The first touch electrode is electrically connected with the first switching device. An area of the first touch electrode is A. The second switching device includes a second channel layer, a second gate, a second source, and a second drain. An overlapping width of the second gate and the second channel layer is W, and an overlapping length of the second gate and the second channel layer is L, W/L>W/L. The second touch electrode is electrically connected with the second switching device. An area of the second touch electrode is A, and A>A
