Abstract: A fingerprint identification apparatus includes a substrate, a second electrode layer, and a first electrode layer. The first electrode layer includes parallel first electrodes, and at least parts of the first electrodes have openings or dents. The second electrode layer includes parallel second electrodes and the second electrodes cross with the first electrodes on the substrate, where the openings or the dents are defined at the cross points from projected view. The second electrode is applied with transmitting signal and the corresponding electric field lines are received by the first electrode. The electric field lines detouring the edges of the first electrodes, or detouring the openings (or the dents) have induction with the finger close to or touching the first electrodes. The number of the effective electric field lines and the effective mutual capacitance changes can be increased to enhance the fingerprint sensing accuracy.
