Fingerprint recognition module, pressure detection method, and fingerprint recognition IC

The invention discloses a fingerprint recognition module, a pressure detection method, and a fingerprint recognition IC. The invention relates to the fingerprint recognition module, and belongs to thetechnical field of fingerprint recognition. The fingerprint recognition module comprises a fingerprint sensor module, the fingerprint recognition IC and a reference electrode which is disposed belowthe fingerprint sensor module. The fingerprint sensor module is electrically connected with the fingerprint recognition IC, and the fingerprint sensor module comprises an induction electrode. When thefingerprint recognition IC detects a fingerprint input operation, the pressure value of the fingerprint recognition module can be determined through the monitoring of the capacitance changes betweenthe reference electrode and the induction electrode, so as to facilitate the subsequent differential processing, thereby enlarging the application range of fingerprint recognition, and improving the user experience.
