Abstract

The invention provides a fingerprint identification device and terminal equipment thereof. The device includes: a circuit board; a substrate formed on the upper surface of the circuit board and electrically connected to the circuit board; a fingerprint recognition sensor formed on the upper surface of the substrate away from the circuit board and electrically connected to the substrate; a light source module formed on the substrate The upper surface far away from the circuit board is electrically connected to the substrate; the light source sensing module is formed on the upper surface of the substrate far away from the circuit board and is electrically connected to the substrate; the control module is formed on the upper surface of the substrate far away from the circuit board and is connected to the substrate electrical connection; the cover ring, having a top opening, is formed on the upper surface of the circuit board, and constitutes a packaging space with the circuit board, and the packaging space accommodates the substrate, the fingerprint identification sensor, the light source module, the light source sensing module and the control module; and the molding layer are filled in the packaging space.

Description

technical field [0001] The invention relates to the technical field of biological feature identification, in particular to a fingerprint identification device with a living body detection function and a terminal device thereof. Background technique [0002] Biometric identification technology is the use of human physiological or behavioral characteristics to identify individuals. At present, the physiological characteristics that have been used for biometric identification include hand shape, fingerprint, face shape, iris, retina, pulse, auricle, etc. Among them, fingerprints are the most reliable physiological characteristics, so fingerprint recognition technology is the most widely used. [0003] However, by extracting residual fingerprints, and then using a fingerprint cover made of gelatin, silica gel or rubber, which is consistent with the pattern of the extracted fingerprint, and wearing the fingerprint cover on the finger or a fake finger, the extracted fingerprint ca...
