Abstract

The invention relates to a novel fingerprint recognition sensor. The novel fingerprint recognition sensor comprises a fingerprint recognition array used for detecting finger touch, the fingerprint recognition array comprises a first fingerprint recognition unit and a second fingerprint recognition unit, the first fingerprint recognition unit and the second fingerprint recognition unit are arrayed alternately, and no overlapped regions exist between the first fingerprint recognition unit and the second fingerprint recognition unit. The first fingerprint recognition unit comprises multiple first fingerprint recognition subunits which are transversely arranged at intervals, the second fingerprint recognition unit comprises multiple second fingerprint recognition subunits which are longitudinally arranged at intervals, and various patterns are engraved on the surfaces of the first fingerprint recognition subunits and the surfaces of the second fingerprint recognition subunits respectively. The novel fingerprint recognition sensor has the advantages that good sensitivity is achieved during fingerprint recognition in all directions, and appropriate light transmission is achieved; the intervals are set, so that light transmission is greatly improved; in addition, various patterns are engraved on the surfaces of the fingerprint recognition subunits, in this way, the reflectivity of the fingerprint recognition unit is smaller, and touch feeling is stronger.

Description

technical field [0001] The invention belongs to the technical field of fingerprint identification, in particular to a novel fingerprint identification sensor. Background technique [0002] In recent years, with the development of storage technology, terminal devices such as smart phones and tablet computers store a large amount of personal information and other important data, and its security has become more important. At present, passwords, graphics and other forms are often used to realize the password protection of terminal equipment. However, for encryption methods such as passwords and graphics, users need to remember the set passwords or graphics. In addition, in public places, there is also the danger of password leakage. In order to improve security, it is often necessary to increase the complexity of passwords and graphics, which undoubtedly further increases the difficulty of user memory, causing conflicts between security and ease of use. [0003] Fingerprint ...
