A fingerprint recognition key including a fingerprint recognition module and a flex-rigid printed circuit board is described. The fingerprint recognition module is arranged on one side surface of a first rigid circuit board area of the flex-rigid printed circuit board. A circuit of the fingerprint recognition module is connected to a flexible circuit area of the flex-rigid printed circuit board. A tact switch connected to the flexible circuit area is arranged at a position, corresponding to the position of the fingerprint recognition module, on the other side surface of the rigid circuit board area. A circuit of the flexible circuit area is connected to a circuit of a second rigid circuit board area of the flex-rigid printed circuit board. A mobile terminal and a mobile phone, both including said fingerprint recognition key, are also described.
A fingerprint recognition key, comprising a fingerprint recognition module and a flexible and rigid combination board, wherein:
A mobile terminal comprising a fingerprint recognition key, wherein the fingerprint recognition key comprises a fingerprint recognition module and a flexible and rigid combination board, wherein the fingerprint recognition module is arranged on a first side surface in a first rigid circuit board area of the flexible and rigid combination board, a circuit of the fingerprint recognition module is connected to a flexible circuit area of the flexible and rigid combination board, a dome switch connected to the flexible circuit area is disposed in a position corresponding to a position of the fingerprint recognition module on a second side surface of the rigid circuit board area opposite to the first side surface, a circuit of the flexible circuit area is connected to a circuit of a second rigid circuit board area of the flexible and rigid combination board.
A mobile phone comprising a fingerprint recognition key, wherein the fingerprint recognition key comprises a fingerprint recognition module and a flexible and rigid combination board, wherein the fingerprint recognition module is arranged on a first side surface in a first rigid circuit board area of the flexible and rigid combination board, a circuit of the fingerprint recognition module is connected to a flexible circuit area of the flexible and rigid combination board, a dome switch connected to the flexible circuit area is disposed in a position corresponding to a position of the fingerprint recognition module on a second side surface of the rigid circuit board area opposite to the first side surface, a circuit of the flexible circuit area is connected to a circuit of a second rigid circuit board area of the flexible and rigid combination board.
