Abstract

The embodiments of the invention provide a fingerprint module and a mobile terminal. The fingerprint module includes a fingerprint identifying chip, a flexible printed circuit and a pressure detectionunit, wherein the pressure detection unit includes a rigid substrate and a pressure detection circuit which is formed on the rigid substrate. The fingerprint identifying chip and the pressure detection unit are respectively disposed on the two opposite surfaces of the flexible printed circuit, and are in separate and electrical connection to the flexible printed circuit. According to the embodiments of the invention, the a pressure detection circuit is directly formed on a rigid substrate, and the rigid substrate is intended for replacing a reinforcing steel sheet as well as a flexible printed circuit which is used for manufacturing a pressure sensor in the prior art. In this way, the system is able to detect pressure, help to thicken the entire fingerprint module, and reduce the influence on the thickness of an entire machine by the fingerprint module.

Description

technical field [0001] The present application relates to the technical field of biometric identification, and in particular, to a fingerprint module and a mobile terminal. Background technique [0002] As a convenient and practical biometric technology, fingerprint unlocking function is widely used in terminal devices such as smart phones. In order to further enhance the user's experience, some terminal devices in the prior art also integrate the function of the pressure sensor into the fingerprint module, so that the fingerprint module can recognize the pressure on it, and according to the pressure Notify the main control chip to trigger the corresponding function. [0003] Generally speaking, the above-mentioned pressure sensor is made based on a flexible circuit board, which is usually directly attached to the underside of the reinforcing steel sheet of the fingerprint module by laminating glue, and the reinforcing steel sheet is mainly used to improve the fingerprint m...
