Referring to Fig. 1 to Fig. 4, the structural schematic diagram of display module provided in an embodiment of the present invention is shown in figure.Extremely such as Fig. 1
Shown in Fig. 4, which includes：Display screen 1, infrared fileter 3 and infrared sensitive chip 5.
Wherein, display screen 1 is the screen of light-permeable comprising the display surface (upper table shown in Fig. 2 and Fig. 3 being disposed opposite to each other
Face) and the back side (Fig. 2 and Fig. 3 shown in lower surface).
Specifically, display screen 1 can be Organic Light Emitting Diode (Organic Light-Emitting Diode, OLED)
Display screen.Certainly, the type of display screen 1 is not limited thereto, and only need to ensure 1 light-permeable of display screen, the embodiment of the present invention
Any restriction is not done to the type of display screen 1.
Infrared fileter 3 is located at the back side of display screen 1, and opposite with the entire display area of display screen 1.
It is understood that infrared fileter 3 is spike filter, it is used for through infrared light and filters other colors
Light.In general, spike filter uses principle of interference, it is made of tens layers optical coating.
It should be pointed out that since infrared fileter 3 is located at the back side of display screen 1, and with the entire viewing area of display screen 1
Domain is opposite, therefore the light for penetrating the entire display area of display screen 1 can be received by infrared fileter 3, in this way, infrared filtering
Piece 3 can penetrate the infrared light in the light from entire display area.
Infrared fileter 3 is between display screen 1 and infrared sensitive chip 5, and infrared sensitive chip 5 is in infrared fileter 3
On frontal projected area be greater than or equal to infrared fileter 3 area, infrared sensitive chip 5 be used for coming from infrared fileter 3
Infrared light handled.
Wherein, display screen 1, infrared fileter 3 and 5 three of infrared sensitive chip can be arranged in parallel.Infrared sensitive chip 5
Can be infrared CMOS complementary metal-oxide-semiconductor (Complementary Metal Oxide Semiconductor,
CMOS), certainly, the type of infrared sensitive chip 5 is not limited to infrared CMOS, only need to ensure that infrared sensitive chip 5 can be right
Infrared light is handled, and the embodiment of the present invention does not do any restriction to the type of infrared sensitive chip 5.
Since frontal projected area of the infrared sensitive chip 5 on infrared fileter 3 is greater than or equal to the face of infrared fileter 3
Product, can be received through all infrared lights of infrared fileter 3 by infrared sensitive chip 5.
In display module provided in an embodiment of the present invention, 1 light-permeable of display screen, in this way, the light outside display module
It can be propagated at infrared fileter 3 through display screen 1.Next, infrared fileter 3 can penetrate the light from display screen 1
In infrared light, which can propagate at infrared sensitive chip 5.Later, infrared sensitive chip 5 can be infrared to coming from
The infrared light of optical filter 3 is handled, to realize infrared imaging.

Outer photoinduction is poor, it is difficult to be sensed, wavelength is too near to visible light in the wavelength of 800 nanometers of infrared lights below, easily
It is interfered by visible light.In view of this, in the present embodiment, infrared fileter 3 only transmits wavelength at 800 nanometers to 1000 nanometers
Between infrared light, so on the one hand can ensure irritability of the display module to infrared light, on the other hand can be to avoid visible
The interference of light.
In addition, RGB cameras are usually provided in mobile terminal, to obtain the plane information of subject.Due to moving
Infrared sensitive chip 5 in dynamic terminal can obtain the spatial information of subject, the sky obtained according to infrared sensitive chip 5
Between information, and the plane information of subject for coordinating RGB cameras to obtain can synthesize to obtain three-dimensional (three
Dimensional, 3D) image.Specifically, under recognition of face scene, mobile terminal can acquire face by RGB cameras
Flat image information, and coordinate infrared sensitive chip 5 obtain face spatial image information, with synthesis obtain with 3D effects
The facial image of fruit, to realize 3D face shooting functions.
As can be seen that in the present embodiment, mobile terminal can have 3D shooting functions.By infrared filtering in this present embodiment
Piece 3 can not only ensure the line of induction to infrared light, but also can be to avoid the interference of visible light, therefore, the 3D shooting effects of mobile terminal
Fruit can preferably be ensured.
