  • Patent number: 10739134
    Abstract: Embodiments of the present invention relate to the technical field of fingerprint sensor detection, and in particular, relate to a method and system for detecting a thickness of a protection layer of a fingerprint sensor. The method includes the following steps: step a: collecting fingerprint data via a fingerprint sensor, the fingerprint sensor comprising a plurality of chip sensing units, arranged in an array; step b: calculating a derivative of the fingerprint data, normalizing the derivative of the fingerprint data, and calculating an integration according to the normalized derivative of the fingerprint data; and step c: acquiring a thickness of a protection layer of the fingerprint sensor according to the integration result.

  • Patent number: 10643048
    Abstract: A fingerprint sensor and a correction method thereof are provided. The fingerprint sensor includes a sensing part to be touched by a finger, including sensing units, a processing unit, and a correction unit; the sensing unit is configured to sense, when correction starts, a fingerprint signal and output first data; the processing unit is configured to calculate, according to a mathematical model, a new correction coefficient of the corresponding sensing unit by the first data; and the correction unit is configured to correct, according to the new correction coefficient, second data output by the corresponding sensing unit. The fingerprint sensor can automatically modify a correction coefficient when a physical characteristic of the fingerprint sensor changes, thereby reducing the product return rate and prolonging the product service life, omitting a step of correction before delivery, and reducing the manufacturing difficulty and the manufacturing costs.
