A touch apparatus includes a plurality of first sensing electrodes, a plurality of second sensing electrodes, and a plurality of third sensing electrodes. The first sensing electrodes extend along a first direction. The second sensing electrodes are electrically isolated from the first sensing electrodes, and extend along a second direction. The plurality of third sensing electrodes are electrically isolated from the second sensing electrodes, and extend along the first direction. At least some of the first sensing electrodes, at least some of the second sensing electrodes, and at least some of the third sensing electrodes are formed at different film layers respectively.
