First embodiment
Fingerprint mould group 100 under a kind of screen is present embodiments provided, to change existing fingerprint mould group by the thickness of terminal device
Degree limitation, shorter, the problem for causing fingerprint recognition precision lower of fingerprint light path of light distance.As a kind of application scenarios, this reality
Applying fingerprint mould group 100 under the screen of example offer can apply in smart phone, tablet computer and other shiftings with display screen
Dynamic terminal device or other terminal devices.
Referring to Fig. 1, Fig. 1 shows the schematic diagram of fingerprint mould group 100 under screen provided in this embodiment, shield lower fingerprint mould group
100 include self light emitting display panel, bracket 120, prism 130, camera lens 140, fingerprint recognition chip 160 and substrate 170, bracket 120,
Prism 130, camera lens 140, fingerprint recognition chip 160 and substrate 170 be arranged in the lower section of self light emitting display panel regional area or
Whole region, to form (Under-display) optical fingerprint identification system under screen.It should be noted that relative to user
For what finger touched touches one side surface of screen, bracket 120, prism 130, camera lens 140, fingerprint recognition chip 160 and substrate 170 are set
Set the lower section that is to say screen in the other side of screen.
Self light emitting display panel is using spontaneous light display unit as display pixel, such as Organic Light Emitting Diode (Organic
Light-Emitting Diode, OLED) display screen or micro-led (Micro-LED) display screen.To use
For OLED display screen 110, referring to Fig. 3, Fig. 3 shows the schematic diagram of OLED display screen 110.Refer to down typically, for screen
For line mould group 100, OLED display screen 110 includes finger-print region 113, and finger-print region 113 can be OLED display screen 110
The specific region in certain (e.g., virtual HOME key), finger-print region 113 can also be whole areas of OLED display screen 110
Domain.When the finger of user touches or presses finger-print region 113, OLED display screen 110 shines and is radiated on the fingerprint of user, instead
It penetrates to form fingerprint light, fingerprint mould group identification fingerprint light obtains finger print information, verifies so as to the identity to user.
It is to be appreciated that self light emitting display panel further includes non-finger-print region 112, in this present embodiment, non-finger-print region 112 refers to
Other regions other than the finger-print region 113 of OLED display screen 110, non-finger-print region 112 are arranged far from the side of user's finger
