dc.description.abstract | A capacitance-type fingerprint sensor. The capacitance-type fingerprint sensor includes a plurality of pixel groups, each of which electrically connects a plurality of sensing electrodes to a plurality of coupling electrodes, respectively; a plurality of first sensing-electrode switches for connecting the sensing electrodes to a voltage source; a plurality of second sensing-electrode switches for interconnecting the sensing electrodes contained in the pixel groups; a plurality of third sensing-electrode switches for interconnecting the pixel groups; and a plurality of coupling-electrode switches for interconnecting the coupling electrodes contained in all pixel groups. Therefore, the fingerprint sensor blocks or corrects capacitance generated by internal components of a fingerprint sensor, such that it acquires a high-quality fingerprint image. Also, the fingerprint sensor corrects or reduces the influence of the dry or moist state of a finger surface, such that a fingerprint image can be more uniformly indicated. | - |
