Touch pad

摘要

A touch pad includes a first transparent substrate and a second transparent substrate. The first transparent substrate has a plurality of first axial electrodes and at least one hollow channel. The second transparent substrate has a plurality of second axial electrodes. Each of the second axial electrodes has a plurality of first sensing electrode regions and at least one second sensing electrode region. The first sensing electrode regions are provided on both sides of the second sensing electrode region and arranged to extend along a second direction. The central portion of the second sensing electrode regions is formed with a hollow region. By means of the first axial electrode and the second axial electrode, the touch pad of the present invention has an increased signal-to-noise ratio and an enhanced anti-jamming capability.
