Fingerprint identification unit and device
The present disclosure provides a fingerprint identification unit. The fingerprint identification unit includes a substrate, a reception layer, a first electrode layer, a transmission layer, a second electrode layer, and a third electrode layer. The reception layer is positioned at one side of the substrate. The first electrode layer is formed on the reception layer. The transmission layer is positioned at another side of the substrate opposite to the reception layer. The second electrode layer and the third electrode layer are formed on two opposite sides of the transmission layer respectively. The reception layer and the transmission layer are made of piezoelectric materials. At least one of the first electrode layer, the second electrode layer, and the third electrode layer is a transparent conductive layer.
