Abstract:
The present disclosure relates to the technical field of biometric identification, and in particular, a fingerprint identification apparatus. The fingerprint identification apparatus includes: a substrate, a sensing chip, a first covering layer, and a second covering layer; wherein the sensing chip is arranged on the substrate, the first covering layer is coated over the sensing chip, the second covering layer is coated on an upper surface of the first covering layer, and the second covering layer is an oleophobic and hydrophobic coating. In the fingerprint identification apparatus according to the embodiment of the present disclosure, a hydrophobic and oleophobic coating is arranged on the surface of the fingerprint identification apparatus, where the density of the hydrophobic components is increased and the hydrophobic as well as oleophobic capabilities are enhanced, and thus the fingerprint identification accuracy and fingerprint identification speed in a wet-finger use environment are improved.
