Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out clearly the technical solution of the utility model embodiment
Chu is fully described by.
Referring to Fig. 1, Fig. 1 is a kind of display screen component 10 provided by the embodiment of the utility model.The display screen component
10 include fingerprint Identification sensor 1, touch screen 3 and light-emitting component 4.The touch screen 3 is the screen with touch function, described
Touch screen 3 has the first face 31 and the second face 34 being oppositely arranged.Wherein, when display screen component 10 is used for electronic equipment, the
On one side 31 relative to the second face 34 close to the other elements such as the mainboard of electronic equipment and battery.First face 31 has transparent area
33 and reflective areas 35.Transmission line 3a, the transmission line 3a are formed between the reflective areas 35 and second face 34
It can be used for conducting the optical signal a that the light-emitting component 4 is emitted.The light-emitting component 4 and the touch screen 3 are at least partly
Surface is oppositely arranged.Specifically, the light-emitting component 4 can towards the touch screen 3 it is any one or more surfaces.Further
Ground, light-emitting component 4 can be towards the side of the touch screen 3 or the first faces 31 of touch screen 3.
Referring to Fig. 1, the light-emitting component 4 is used to emit optical signal a towards the touch screen 3.The transmission line
3a is for conducting the optical signal a, so that the partial optical signal a penetrates second face 34 and is reflected by fingerprint lines,
Form target optical signal b.The target optical signal b carries finger print information.The transparent area 33 is used to believe through the target light
Number b.Transparent area 33 described in the fingerprint Identification sensor 1 at least partly face, the fingerprint Identification sensor 1 is for receiving institute
Target optical signal b is stated, and the target optical signal b is converted into electric signal, to identify the fingerprint letter according to the electric signal
Breath, and then realize receiving and recognizing for finger print information.
It should be understood that optical signal a is greater than the aerial refractive index of optical signal a in the refractive index of the touch screen 3, when
Incidence angle of the optical signal a that light-emitting component 4 is emitted at touch screen 3 Yu the interface of air is greater than the full transmitting angle of optical signal a
When, optical signal a will be totally reflected in the touch screen 3, after in touch screen 3 multiple total reflection occurs for the optical signal a
Realization is transmitted in entire touch screen 3, so that optical signal a emitted by light-emitting component 4 is transmitted in entire touch screen 3.
Referring to Fig. 1, when the second face 34 of the fingerprint lines F of user's finger touching touch screen 3, since optical signal a exists
Refractive index in finger is greater than refractive index of the optical signal a in touch screen 3, so optical signal a will be projected simultaneously out of touch screen 3

Drain electrode 243 is located on the same floor with the photosensitive layer 111.Filter layer 113 can be same layer, micro-lens with flatness layer 244
114 can be with pixel electrode layer 245 in same layer.In other embodiments, photosensitive layer 111 may be located on thin film transistor (TFT) 24
The other structures layer of substrate 23；Or photosensitive layer 111 may be located on the outer surface of thin film transistor (TFT) round substrate 23；Or it is photosensitive
Layer 111 may be located in other layers except thin film transistor (TFT) round substrate 23.In other embodiments, 113 He of filter layer
Micro-lens 114 can be located at the outer surface of thin film transistor (TFT) round substrate 23, alternatively, filter layer 113 and micro-lens 114 can
Other layers between thin film transistor (TFT) round substrate 23 and touch screen 3 to be located at display screen component 10.
Figure 21 is please referred to, Figure 21 is a kind of electronic equipment 100 provided in this embodiment, and the electronic equipment 100 includes upper
State display screen component 10 described in any one embodiment.It should be understood that electronic equipment 100 can be such as mobile phone, pen
Note sheet, palm PC, electronic reader, TV device, intelligent appliance, intelligent operation screen, smart home, wearable electronic are set
Standby, Vehicular display device etc. has the electronic equipment of touch-control and display function.
Figure 21 is please referred to, the electronic equipment 100 further includes frame 30.The frame 30 surrounds the side of the touch screen 3
Face 32.The light-emitting component 4 can be abutted far from one end of the touch screen 3 on the inner wall of the frame 30.In other implementations
In example, multiple accommodating chamber 30a can be set on the inner wall of frame 30, so that light-emitting component 4 is contained in accommodating chamber 30a.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these are improved and profit
Decorations are also considered as the protection scope of the utility model.
