Fingerprint identification module

Abstract

The present invention provides a fingerprint identification module. The fingerprint identification module (10) comprises a ceramic cover plate (12) and a fingerprint identification chip (13) which are arranged from top to bottom. An annular conductive part (121) is integratedly formed at the outer edge of the upper surface of the ceramic cover plate (12). The annular conductive part (121) and the fingerprint identification chip (13) are connected through a conductive wire (14). According to the fingerprint identification module, through integratedly forming the annular conductive part (121) with a conductive function at the outer edge of the upper surface of the ceramic cover plate, the annular conductive part can substitute a metal ring to realize the function of the metal ring, the problem of a height difference brought by the existence of the metal ring is avoided completely, the problems of finger cut by protruding edges and dust dead corners do not exist, structural parts are reduced, the problem of an assembly error is completely avoided, and the product precision is improved while the cost is saved.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint identification module with a fingerprint identification function. Background technique [0002] Fingerprint identification is to match a person with his fingerprints, and to verify the person's true identity by comparing the detailed feature points of different fingerprints of this person with the pre-saved fingerprints. With the development of science and technology, the application fields of fingerprint recognition are becoming more and more extensive. In addition to access control and attendance systems, devices with touch screens such as laptops and mobile phones have realized the fingerprint recognition function. [0003] figure 1 Shown is a schematic structural diagram of a fingerprint recognition module used on a mobile phone. The fingerprint recognition module 10 shown in the figure includes a metal ring 11, a glass cover 12, a fingerprin...

AI Technical Summary

Problems solved by technology

[0004] The problem with the above-mentioned fingerprint recognition module 10 is that the metal ring 11 is arranged around the glass cover 12 and protrudes outside the upper surface of the glass cover 12, and its protruding edge is easy to scratch fingers, and because the metal ring 11 and the glass cover There is a height difference on the upper surface of the board 12, and the user feels that it is not smooth when touched, which affects the operating experience, and the height difference between the two is easy to form a dead corner where dust and dirt gather, which is difficult to remove

In addition, due to the obvious color difference between the metal ring 11 and the glass cover 12, the visual experience is very poor, which affects the appearance of the product.
