Problems solved by technology

[0005] When applied to portable mobile devices, hardware production cost control is particularly important, so the area of ​​the sensing area will be continuously reduced, eventually resulting in the need for multiple entries to unlock, which greatly prolongs the fingerprint recognition time and reduces the fingerprint recognition sensor. Sensitivity, reducing user experience
If the conventional solution is followed, in order to ensure the speed of fingerprint recognition, the increased sensing area will increase the hardware cost

Abstract

The invention relates to the field of fingerprint identification and discloses a sensing unit scanning method and a fingerprint identification method of a fingerprint identification sensor. The sensing unit scanning method of the fingerprint identification sensor comprises the following steps of A, simultaneously scanning a sensing unit currently in a working state and a plurality of sensing units around the currently-working sensing unit to obtain scanning results; B, finding out a sensing unit working in a next time sequence and a plurality of sensing units around the sensing unit working in the next time sequence according to a present sequence; C, repeating steps A and B until scanning of all the sensing unit needs to work finished. According to the sensing unit scanning method of the fingerprint identification sensor, the number of the sensing units which can be scanned with the currently-working sensing unit simultaneously can be increased, sensing area during scanning each time can be expanded, by means of the improvement in scanning methods of the sensing units, sensing areas during scanning each time can be increased, sensitivity of the fingerprint identification sensor can be improved and user experience can further be improved.

Description

technical field [0001] The invention relates to the field of fingerprint identification, in particular to a scanning method of an inductive unit of a fingerprint identification sensor and a fingerprint identification method thereof. Background technique [0002] Fingerprint identification technology is a high-tech developed recently. Fingerprint identification is a technology that uses the unique and invariable physiological characteristics of the human body to use fingerprints as a "living ID card" for the human body or a special seal that is carried around for identification. [0003] Existing fingerprint detection relies on the unevenness of the fingerprint, that is, the difference between the valleys and ridges on the fingerprint, and the so-called fingerprint pattern is extracted by detecting the capacitance value change between the electrode and the finger during the movement of the finger. [0004] At present, the sensing area of ​​the mainstream fingerprint recognit...
