Abstract
A sensing device has a first substrate, a second substrate, a plurality of sets of first electrodes, a plurality of second electrodes, a plurality of first axis signal lines, a plurality of second axis signal lines, and a plurality of second signal lines. The second substrate is above the first substrate and has a reset structure. The second electrodes are on the first surface of the second substrate in array. Each set of first electrodes is on the first substrate in array, corresponding to one of the plurality of second electrodes, and having at least one first axis electrode and at least one second axis electrode. The first axis electrode and the second axis electrode both partially overlap with the corresponding second electrode.
