Abstract

Some embodiments of the present application provide a fingerprint module and a mobile terminal. The fingerprint module includes a fingerprint recognition chip, a flexible circuit board and a pressure detection unit, wherein the pressure detection unit includes a hard substrate and a pressure detection circuit formed on the hard substrate; the fingerprint recognition chip and the pressure detection unit are respectively arranged on the flexible circuit board. The two opposite surfaces are respectively electrically connected to the flexible circuit board. In the embodiment of the present application, the pressure detection circuit is directly formed on the hard substrate, and the rigid substrate provided with the pressure detection circuit is used to replace the reinforcing steel sheet in the prior art and the flexible circuit board for making the pressure sensor. This design method can not only ensure the realization of the pressure detection function, but also help to reduce the overall thickness of the fingerprint module, and reduce the impact of the fingerprint module on the thickness of the whole machine.

Description

technical field [0001] The present application relates to the technical field of biometric identification, in particular to a fingerprint module and a mobile terminal. Background technique [0002] As a convenient and practical biometric technology, the fingerprint unlocking function is widely used in terminal devices such as smartphones. In order to further enhance the user 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 applied to 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 through bonding glue, and the reinforcing steel sheet is mainly used to improve the fingerp...
