To be fixed in groove by conductive or non-conductive double-sided adhesive.For example, can be in the lower surface of fingerprint identification device 430 or recessed
Rooved face attaches double-sided adhesive, and applies certain pressure in the upper surface of fingerprint identification device 430, by itself and groove fixed bonding.
Alternatively possible embodiment are as follows: the fingerprint identification device 430 can pass through mechanical connection manner by dedicated location structure
It is fixed on groove surfaces.For example, screw installation fixed form, mode and coupling fixed form etc. is welded and fixed.
Wherein, the depth of the groove can be less than or equal to 0.3mm, and the thickness of center 440 is generally 0.6mm, in order not to
Other performances of electronic equipment are influenced, guarantee that the thickness for having the thinnest part of reeded center 440 is greater than or equal to as far as possible
0.2mm, it should be appreciated that the depth of groove can be related to the thickness of center, and parameters value is used only for example herein, does not make to have
Body limits.
The display screen 420 used in the technical solution of the embodiment of the present application can be OLED screen, soft screen or hard screen, with
Under be explained in detail by taking OLED screen as an example.If the fingerprint identification device 430 is optical fingerprint identification device, which knows
The optical signal that other device 430 needs to detect the display screen 420 sending passes through the reflected light that finger reflects to form, fingerprint recognition dress
At least 50 μm of the air gap should be kept by setting between 430 and display screen 420.There can also be one layer of screening below display screen 420
The laminations such as photosphere, screen protection foam, optical cement, screen assembly flexible circuit board are needed by each lamination aperture, so that this refers to
Line identification device 430 is at least partially housed in aperture, effectively to receive the light penetrated from display screen 420.The bore size phase
For electronic equipment, it can laterally be less than or equal to 30mm along screen, it is longitudinal then less than or equal to 60mm along screen, or
Person, shielding lower lamination bore size can extend outwardly 0.7~1.5mm relative to the outer dimension of fingerprint identification device.This field
