According to one embodiment of the underscreen fingerprint assembly of the present invention, a surface of the black silicone sleeve facing the fingerprint FOV area does not interfere with the fingerprint FOV area.

According to one embodiment of the underscreen fingerprint assembly, the surface of the black silica gel sleeve is parallel to and spaced from the boundary of the FOV area of the fingerprint.

According to one embodiment of the underscreen fingerprint assembly of the present invention, a distance between a surface of the black silicone sleeve and the FOV area of the fingerprint is 0.3-0.5 mm.

According to one embodiment of the fingerprint assembly under the screen, one side of the front shell surrounding the FOV area of the fingerprint is a step surface, and the black silica gel sleeve is attached to the step surface and the shape and the size of the black silica gel sleeve are matched with those of the step surface.

According to one embodiment of the underscreen fingerprint assembly, the black silicone sleeve is directly and hermetically fixed on the surface of the front shell facing the FOV area of the fingerprint.

Compared with the prior art, the area surrounding the FOV of the fingerprint is provided with the black silica gel sleeve, and the black silica gel sleeve is sealed, light-tight and non-reflective, so that a good optical working environment can be provided, and the periphery of the FOV area of the fingerprint is free from reflection to interfere with the normal work of the fingerprint. In addition, black silica gel cover's setting can reduce processes and materials such as seal black, sealed bubble cotton, not only can realize simplifying the structure, but also can reduce manufacturing cost.
