Background

Fingerprint identification (fingerprint identification) is the most typical identification system in the biometric identification technology, and comprises a fingerprint image acquisition module, a fingerprint image processing module, a fingerprint form and detail feature extraction module and a fingerprint comparison module. The fingerprint image acquisition module acquires a fingerprint image by using a fingerprint acquisition instrument. Fingerprint scanners are classified into optical, capacitive, and pressure-sensitive types, wherein the capacitive type is widely used in various electronic devices. With the development of light and thin market demand of electronic devices, especially mobile phones and other communication mobile terminals, the requirement for the structural design of each module of the fingerprint identification system is higher and higher.

The existing fingerprint identification module has two methods: one is the scheme adopted by apple, incorporated below the HOME key, and the other is the scheme adopted by hua mao. In the scheme adopted by Huashi corporation, a fingerprint identification sensing area is added on the back of the mobile phone to realize the fingerprint identification function. The existing methods of fingerprint identification modules all need to specially set a through hole on a mobile phone shell for setting a fingerprint sensing lens, which not only affects the appearance of electronic equipment, but also increases the manufacturing cost.
