Fingerprint identification key, mobile terminal and mobile phone

Abstract

The invention provides a fingerprint identification key, which comprises a fingerprint identification module, and further comprises a rigid-flex board, wherein the fingerprint identification module is arranged on the surface at one side of a first rigid circuit board region of the rigid-flex board; a circuit of the fingerprint identification module is connected to a flexible circuit area of the rigid-flex board; a touch switch connected to the flexible circuit area is arranged on a place corresponding to the position of the fingerprint identification module on the surface at the other side of the rigid circuit board region; and a circuit of the flexible circuit area is connected to a circuit of a second rigid circuit board area. The invention also provides a mobile terminal and a mobile phone. Each of the mobile terminal and the mobile phone comprises the fingerprint identification key. Compared with the prior art, through replacing a reinforcing steel sheet in the fingerprint identification key with the rigid-flex board and respectively arranging the fingerprint identification module and the touch switch on the surfaces at the two sides of the rigid circuit board of the rigid-flex board, the space is saved, the structure is reliable and the rigidity of the fingerprint identification key is improved.

Description

technical field [0001] The invention relates to a fingerprint identification technology, in particular to a fingerprint identification button, a mobile terminal and a mobile phone. Background technique [0002] At present, as people's requirements for privacy and security are getting higher and higher, many mobile terminal manufacturers will promote privacy and security as an important selling point when it comes to products, resulting in mobile terminals basically equipped with fingerprint recognition functions. The existing design of fingerprint identification buttons mainly uses flexible circuit boards and reinforcing steel sheets as carriers for fingerprint sensors, tact switches and wiring, because the reinforcing steel sheets are only used to partially reinforce the flexibility of this area. The process of preventing the circuit board from bending, after setting the tact switch and pressing the tact switch several times, because the reinforcing steel sheet is only used...

[0002] At present, as people's requirements for privacy and security are getting higher and higher, many mobile terminal manufacturers will promote privacy and security as an important selling point when it comes to products, resulting in mobile terminals basically equipped with fingerprint recognition functions. The existing design of fingerprint identification buttons mainly uses flexible circuit boards and reinforcing steel sheets as carriers for fingerprint sensors, tact switches and wiring, because the reinforcing steel sheets are only used to partially reinforce the flexibility of this area. The process of preventing the circuit board from bending, after setting the tact switch and pressing the tact switch several times, because the reinforcing steel sheet is only used to reinforce the flexible circuit board so that it will not bend, so He does not have the pressure to withstand multiple presses, so the reinforcing steel sheet is easily deformed and the strength is poor
