Abstract
A self-capacitive touch device includes a transparent substrate, multiple sensing electrodes and multiple trace lines. The sensing electrodes are alternately disposed on the transparent substrate, and each of the sensing units has a polygonal planar contour having M sides, where M is a positive integer equal to or greater than 4. A side of each of the sensing electrodes corresponds to sides of at least two of the remaining sensing electrodes. The trace lines are electrically connected to the sensing electrodes in a way that a part of segments of the trace lines are disposed in an active region of the self-capacitive touch device.
