In one embodiment, referring to fig. 7, the display screen 210 includes a cover 2101, a liquid crystal panel 2102 and a light module 2103. The liquid crystal panel 2102 is attached to the display cover 2101. The fingerprint module 100 and the signal gathering device 30 are fixed between the light emitting module 2103 and the liquid crystal panel 2102. The light emitting module 2103 may provide backlight to the liquid crystal panel 2102. The light emitted from the light emitting module 2103 can form a display image through the liquid crystal panel 2102 and exit through the transparent region.
The liquid crystal panel 2102 may be attached to the display cover 2101 by an optical adhesive. The liquid crystal panel 2102 is provided with a liquid crystal region 2104 and an encapsulation region 2105 encapsulating the liquid crystal region 2104.

The fingerprint module 100 and the signal gathering device 30 are fixed between the driving portion 2111 and the display cover 2101. The light-emitting module 2103 may be disposed obliquely relative to the display screen cover 2101, or may be disposed in parallel with the display screen cover 2101.
