Fingerprint recognition unit and fabrication method thereof, fingerprint recognition module and display device
The present disclosure provides a fingerprint recognition unit and a fabrication method thereof, a fingerprint recognition module and a display device. The fingerprint recognition unit includes: a bearing substrate; a receiving electrode layer on the bearing substrate; a piezoelectric material layer on a side of the receiving electrode layer away from the bearing substrate; and a driving electrode layer on a side of the piezoelectric material layer away from the receiving electrode layer. A density of the driving electrode layer is greater than 5 g/cm3, and a thickness of the driving electrode layer, a thickness of the piezoelectric material layer and a thickness of the bearing substrate are configured such that a vibration nodal plane of the piezoelectric material layer is within the piezoelectric material layer.
