Abstract: An electronic device with fingerprint recognition circuit powered by dedicated power source includes a functional circuit, a plurality of fingerprint sensing electrodes, and a fingerprint sensing control circuit. The functional circuit is powered by a first power source. The fingerprint sensing electrodes are provided for sensing a contact of a finger. The fingerprint sensing control circuit is powered by a second power source which is different from the first power source.

Abstract: A touch control method is provided. The method includes: providing a touch device with multiple touch electrodes; determining whether an object is located in a sensing distance; detecting a sensing group sensing the object if the determination is yes; determining whether an electrode amount in the electrode group is between a first value and a second value; determining whether a sensing time of a predetermined proportion of the touch electrodes in the sensing group is equal to or greater than a predetermined time; executing a fingerprint recognition mode if the electrode amount is between the first value and the second value, and the sensing time is equal to or greater than the predetermined time; executing a touch operation mode if the electrode amount is less than the first value or greater than the second value, or the sensing time is less than the predetermined time.

Abstract: A rapid identification method for fingerprint first provides a fingerprint identification apparatus having a fingerprint sensing area and divides the fingerprint sensing area into fingerprint sensing sub-regions. In a registration stage, the method performs fingerprint sensing for the entire fingerprint sensing area to obtain fingerprint image for a whole fingerprint sensing area, fingerprint minutiae and relevant locations for the fingerprint minutiae and then pre-stores those data. In an identification stage, the method performs fingerprint sensing on a part of the fingerprint sensing sub-regions for a user to be identified and detects fingerprint minutiae and relevant locations for the fingerprint minutiae in the part of the fingerprint sensing sub-regions. The method compares the fingerprint minutiae and relevant locations detected in the identification stage with respect to the corresponding fingerprint minutiae and relevant locations in the registration stage in order to determine whether the user can be granted with access right.

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.
