Biometric feature recognition device and electronic equipment

Abstract

The invention provides a biometric feature recognition device and electronic equipment with the biometric feature recognition device. The biometric feature recognition device comprises a chip set, a dielectric cover plate which is placed on the chip set and a first wire set which is placed on the dielectric cover plate. The first wire set is connected with the chip set, and the first wire set provides pulse signals for a finger when the finger of a user makes contact with the biometric feature recognition device. The biometric feature recognition device has the advantages that integration density is high, and subsequent processing difficulty is low; the device can be manufactured to be of an ultrathin structure, so that the ornamental value is high; in addition, the inside of the biometric feature recognition device can be protected, and thus the degree of safety is high.

Description

technical field [0001] The invention relates to the technical field of biological feature identification, in particular to a biological feature identification device and electronic equipment with the biological feature identification device. Background technique [0002] A new generation of electronic equipment uses a fingerprint recognition device or an optical imaging device that slides with a finger. However, the sensitivity of the fingerprint recognition device is poor. There are stains on the user's finger or the direction of the user's finger sliding is not good, which will cause the fingerprint recognition device to fail. Failure, and the fingerprint of the user is easily copied, resulting in poor security of the fingerprint identification device. In addition, optical imaging devices also have similar security risks. [0003] At present, capacitive sensing fingerprint recognition devices have begun to be used in the new generation of electronic equipment. However, th...

[0002] A new generation of electronic equipment uses a fingerprint recognition device or an optical imaging device that slides with a finger. However, the sensitivity of the fingerprint recognition device is poor. There are stains on the user's finger or the direction of the user's finger sliding is not good, which will cause the fingerprint recognition device to fail. Failure, and the user's fingerprint is easy to be copied, resulting in poor security of the fingerprint recognition device

In addition, optical imaging devices also have similar safety hazards

[0003] At present, capacitive sensing fingerprint recognition devices have begun to be used in the new generation of electronic equipment. However, the structure of capacitive sensing fingerprint recognition devices is very complicated, and the requirements for raw material technology and module packaging technology are very high during production. Therefore, Not only the production efficiency and yield rate are very low, but also the production cost is high
