The glass cover 200 includes a visible portion 220 and a frame portion 210, and a visible portion 220 corresponds to the display screen 300. The visible portion 220 is used to observe the image of the display screen 300, and the frame portion 210 is disposed at the edge of the visible portion 220, that is, the frame portion 210 is disposed around the visible portion 220. A receiving structure 400 is disposed on the display screen 300 and the visible portion 220. The fingerprint recognition module 100 is embedded in the receiving structure 400.

Referring to FIG. 3 , in one embodiment, the accommodating structure 400 includes a first mounting hole 210 and a second mounting hole 310 . The first mounting hole 210 is disposed on the visible portion 220 of the cover glass 200 , and the second mounting hole 310 . The display hole 300 is disposed opposite to the first mounting hole 210 and the second mounting hole 310. The first mounting hole 210 and the second mounting hole 310 may be circular holes, square holes or other polygonal holes, or other irregular shapes. Hole.

Referring to FIG. 3, in the embodiment, the first mounting hole 210 is a first circular through hole 211, and the second mounting hole 310 is a second circular through hole 311, and the first circular through hole 211 and the second circular shape The through holes 311 are coaxially disposed, and the diameter of the first circular through holes 211 is smaller than the diameter of the second circular through holes 311. Of course, it can be understood that the diameter of the first circular through hole 211 may be greater than or equal to the diameter of the second circular through hole 311.

Referring to FIG. 2 and FIG. 3 , the fingerprint identification module 100 has a T-shaped structure, and the fingerprint identification module 100 includes a first mounting portion 110 and a second mounting portion 120 each having a cylindrical structure. The first mounting portion 110 and the first mounting portion 110 A circular through hole 211 is engaged, and the second mounting portion 120 is engaged with the second circular through hole 311.

When the diameter of the second circular through hole 311 is larger than the diameter of the first circular through hole 211, the diameter of the second mounting portion 120 is larger than the diameter of the first mounting portion 110, and the second mounting portion 120 is adjacent to the glass cover 200. The side is in contact with the glass cover 200. At this time, the glass cover 200 can provide axial positioning for the fingerprint recognition module 100 such that the upper surface of the second mounting portion 120 is flush with the surface of the cover glass 200. Similarly, when the diameter of the first circular through hole 211 is larger than the diameter of the second circular through hole 311, the diameter of the first mounting portion 110 is larger than the diameter of the second mounting portion 120, and the first mounting portion 110 is away from the glass cover. One side of the board 200 abuts the display screen 300, and the display screen 300 can provide axial positioning for the fingerprint recognition module 100 such that the upper surface of the first mounting portion 110 is flush with the surface of the cover glass 200.
