Abstract

The embodiment of the invention discloses a fingerprint recognition module, a preparation method thereof and an electronic device. The fingerprint recognition module comprises a circuit board, a fingerprint recognition unit, at least one first light-emitting unit, a first supporting unit and a packaging unit. The packaging unit comprises a first light-transmitting area, a second light-transmittingarea and a non-light-transmitting area, the first light-transmitting area comprises a plurality of light-transmitting holes arranged in an array mode, and the vertical projection of the first light-transmitting area on the plane where the circuit board is located and the vertical projection of the fingerprint recognition unit on the plane where the circuit board is located have an overlapping area; the vertical projection of the second light-transmitting area on the plane where the circuit board is located and the vertical projection of the first light-emitting unit on the plane where the circuit board is located have an overlapping area. By arranging the first light-transmitting area and the second light-transmitting area on the packaging unit, it is guaranteed that light emitted by thefirst light-emitting unit can be reflected into the fingerprint recognition unit after passing through a finger, meanwhile, the non-light-transmitting area is arranged outside the first light-transmitting area and the second light-transmitting area, and personalized setting of the optical fingerprint recognition module can be achieved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of fingerprint identification, and in particular to a fingerprint identification module, a preparation method thereof, and an electronic device. Background technique [0002] At present, fingerprint recognition, as the mainstream biometric means, is widely used in all aspects of people's lives, and the most common and most relevant to daily life is the application in clock-in machines at work. [0003] The fingerprint identification module can be divided into an optical fingerprint identification module and a capacitive fingerprint identification module. Generally speaking, because the capacitive fingerprint recognition module does not use a backlight, it can realize the personalized setting of the appearance color to a certain extent, such as using a coating or a glass cover. Generally speaking, the thickness of the coating or glass on the surface of the capacitive fingerprint chi...
