Many details are explained in the following description in order to fully understand the application, described embodiment
Only a part of embodiment of the application, rather than whole embodiments.Based on the embodiment in the application, this field
Those of ordinary skill's every other embodiment obtained without making creative work belongs to the application guarantor
The range of shield.
Referring to Fig. 1, for the planar structure schematic diagram of the display screen 1 in one embodiment of the application.The display screen 1 includes
Display area A0, the display screen further include in array distribution in several display units of the entire display area A0 of display screen 1
11, several infrared emission units 12 on the boundary close display area A0 being distributed in the A0 of display area are distributed in the display
Several acquisition units 13 in the A0 of region.That is, the first predeterminable area A1 is in the A0 of display area, and close to viewing area
The boundary position of domain A0.
Several infrared emission units 12 are used to emit infrared light in front of display screen 1, are located at display to be irradiated to
The iris of the target object in 1 front of screen, several acquisition units 13 are used to acquire the image for the iris that irradiation has infrared light
Signal, described image signal are used to generate the target image for identifying iris feature.
To in the application, by by the identification of the iris feature for identification such as infrared emission unit 12, acquisition unit 13
Component is embedded in the display area A0 of display screen 1, places those knowledges without additionally reserving excessive non-display area
Other component is effectively promoted screen accounting and can satisfy the demand of iris recognition.
In some embodiments, several infrared emission units 12 are distributed in leaning in the A0 of display area to be embedded
In the first predeterminable area A1 on the nearly display area boundary A0, several acquisition units 13 are distributed in the viewing area to be embedded
In the second predeterminable area A2 in the A0 of domain；Several acquisition units 13 are combined into an iris image sensor.That is, being distributed in
Several acquisition units 13 in the A0 of display area have been integrally formed an iris image sensor.
As shown in Figure 1, the second predeterminable area A2 is except the first predeterminable area A1 in the A0 of display area
Region.That is, the summation of the first predeterminable area A1 and the second predeterminable area A2 are the display area A0.Wherein,
Area of the area of the first predeterminable area A1 significantly less than the second predeterminable area A2.
For example, the area of the first predeterminable area A1 can be only 1/5, the 1/6 of the area of the second predeterminable area A2
Deng.Therefore, the first predeterminable area A1 is located only within close to the lesser partial region on the boundary display area A0, described infrared
Transmitting unit 12 is provided only in the lesser partial region on the boundary display area A0.
In some embodiments, it is corresponding that one is provided in the first predeterminable area A1, at each display unit 11
Infrared emission unit 12 is provided with a corresponding photosensitive unit in the second predeterminable area A2 at each display unit 11
13.That is, the quantity of infrared emission unit 12 is identical as the quantity of display unit 11 in the first predeterminable area A1, described
In two predeterminable area A2, the quantity of photosensitive unit 13 is identical as the quantity of display unit 11.Obviously, in other embodiments, exist
In first predeterminable area A1, the quantity of infrared emission unit 12 can be different from the quantity of display unit 11, default described second
In the A2 of region, the quantity of photosensitive unit 13 can also be different from the quantity of display unit 11.
Referring to Fig. 2, for the planar structure schematic diagram of the display screen 1 in another embodiment.In another embodiment, such as
Shown in Fig. 2, the first predeterminable area A1 and the second predeterminable area A2 are overlapped, that is, several infrared emission units 12 and institute
It states several infrared emission units 12 to be distributed in identical region to be embedded, and is to be set close to the boundary of display area A0
It sets.For example, as shown in Fig. 2, the first predeterminable area A1 and the second predeterminable area A2 of the coincidence are disposed proximate to the visual angle Fig. 2
At the side S1 at top.
Wherein, as shown in Fig. 2, in the first predeterminable area A of coincidence and the second predeterminable area, at each display unit 11
It is provided with a corresponding infrared emission unit 12 and a photosensitive unit 13.

It penetrates that unit 12 is equal with the quantity of photosensitive unit 13, and the quantity of the display unit 11 can be more than or less than.For example, can be with
A corresponding infrared emission unit 12 and a photosensitive unit 13 be just set at every two display unit 11, or can also be
Two infrared emission units 12 and two photosensitive units 13 are set at each display unit 11.
In further embodiments, in the first predeterminable area A of coincidence and the second predeterminable area, the infrared emission list
Member 12 and the quantity of photosensitive unit 13 can also be different, that is, the quantity of the infrared emission unit 12 can be more than or less than photosensitive list
The quantity of member 13.
Referring to Fig. 3, for the planar structure schematic diagram of the display screen in another embodiment.As shown in figure 3, further implementing
In example, the quantity of the first predeterminable area A1 be it is multiple, be respectively arranged at the position close to multiple sides of display area A0.
As shown in figure 3, the quantity of the first predeterminable area A1 can be 4, the display area A0 can be approximate rectangular
Region, including four side S1.Four the first predeterminable area A1 are respectively arranged at the position of four side S1 close to display area A0
It sets.It is embedded in each first predeterminable area A1 that several infrared emission units 12 are distributed with.
Wherein, the size of the first predeterminable area A1 can be significantly less than the size of display area A0, for example, viewing area
1/10,1/8 etc. of domain A0.
Wherein, as shown in figure 3, the second predeterminable area A2 is to be overlapped with the first predeterminable area A1, it is clear that when the first preset areas
When domain A1 is multiple, the second predeterminable area A2 also necessarily to be multiple, thus, each coincidence the first predeterminable area A1 and
It is embedded that several infrared emission units 12 and several acquisition units 13 is distributed in second predeterminable area A1.
In some embodiments, the second predeterminable area A2 can be four the first predeterminable area A1 in the A0 of display area
Except region.
Wherein, described several infrared when not being overlapped about the first predeterminable area A1 and the second predeterminable area A2 or when being overlapped
The more specific related introduction of the distribution of transmitting unit 12 and several acquisition units 13 can refer to the description of Fig. 1 and Fig. 2 respectively.
Therefore, in the application, the quantity of the first predeterminable area A1 can be one, be disposed in proximity to display area A0's
The position of one side S1；Alternatively, the quantity of first predeterminable area can be respectively arranged at close to display area A0's to be multiple
The position of multiple side S1.
Wherein, each display unit 11 has corresponded to a pixel of display screen 1, the quantity of the display unit 11 by
The resolution ratio of display screen 1 determines.
Wherein, in the application, the display screen 1 can for OLED (Organic Light Emitting Diode, it is organic
Light emitting diode) display screen, each display unit 11 can be one or more Organic Light Emitting Diode compositions.
