Specific embodiment
It is below in conjunction with the accompanying drawings and concrete real to make those skilled in the art more fully understand the technical solution of the utility model
Apply mode to be described in further detail this utility model.
Embodiment 1：
With reference to shown in Fig. 1, the present embodiment provides a kind of contact panel with fingerprint identification function, and it includes：Array base
Plate 1 and fingerprint recognition substrate 2；Wherein, array base palte 1 includes：First substrate 10；The multiple pixels being arranged in the first substrate 10
Unit, each pixel cell includes thin film transistor (TFT) 11 and organic electroluminescent LED 12；Fingerprint recognition substrate 2 includes：The
Two substrates 20；Fingerprint identification unit 21 in second substrate 20 is set；Fingerprint recognition substrate 2 is located at the first substrate 10 and deviates from pixel
The side of unit；Specifically, also include on the array base palte 1 in the present embodiment：Light shield layer 13, and be arranged at least partly
Via 14 between two adjacent pixel cells, and via 14 is formed in light shield layer 13；Via 14 is used to send out organic electroluminescence
The light that optical diode 12 is sent is exposed in multiple fingerprint identification units 21 after reflecting via touch body surfaces, wherein, touch
Body surfaces are touched including valley and a ridge, the light of the via 14 is reflected by the valley and a ridge of touch body surfaces, exposed to respectively not
In same fingerprint identification unit 21.
Wherein, the touch main body in the present embodiment can include finger, toe, and have appointing for valley and a ridge with surface
What can implement the object for touching.In the present embodiment example is illustrated mainly as a example by touching main body as finger.This enforcement
The contact panel of example arranges fingerprint recognition base in organic electroluminescent LED (OLED) array base palte 1 away from the side of display surface
Via 14 is set between plate 2, and at least part of two adjacent pixel cells on array base palte 1, and the via 14 meets little
Borescopic imaging principle, the light that organic electroluminescent LED 12 is sent reflexes to multiple fingerprint identification units 21 via finger
On, and the light that the valley and a ridge of finger is reflected, expose to respectively in different fingerprint identification units 21, now by analyzing finger
The light intensity magnitude of light that reflects of valley and a ridge, so as to judge valley and a ridge.It is additionally, since and is being provided with via 14, therefore finger
The light for being reflected of far region can then be blocked layer 13 and block, it is impossible to reflect via 14, that is to say, that what via 14 was projected
Light is only the light that finger small area region is reflected, and now finger print information received in fingerprint identification unit 21 is also just more
Plus precisely, therefore beneficial to the judgement of finger valley and a ridge.It is, of course, also possible to be understood by, light shield layer 13 is arranged on OLED array bases
Plate 1 can't affect the aperture opening ratio of the contact panel away from the side of display surface.
Wherein, via number is multiple 14 in the light shield layer 13 of the present embodiment, and any two adjacent via 14
Between spacing be equal to 1~2 times of image distance；(namely via 14 is near fingerprint identification unit for the bottom of via 14 for the image distance
21 side) to the fingerprint identification unit 21 vertical dimension between layers.That is, between two adjacent vias 14
Every multiple pixel cells, why it is arranged such and is because, if the design of via 14 density is overstocked, it will cause adjacent vias 14
The light for transmiting will expose to same fingerprint identification unit 21, cause signal cross-talk, so as to cause valley and a ridge detection not
Accurately.
Wherein, the light that the light for being sent due to the reflective diode of organic electroluminescence is reflected through finger is through array base
Each Rotating fields of plate 1, and after the air layer between array base palte 1 and fingerprint recognition substrate 2, reach in fingerprint identification unit 21
The light intensity of light can decrease；Meanwhile, light, because angle is different, has different light incidence interfaces through via 14,
Although light intensity is closer to, can there are different reflections and absorption in the light of incidence angles degree when different interfaces, this
Sample, as shown in Figures 3 and 4, and fingerprint identification unit 21 (sensor1) light intensity of the corresponding centre of via 14 receive it is most strong, but
As angle increases, fingerprint identification unit 21 (light intensity that sensor2 and sensor3 are received is less than the light intensity that sensor1 is received)
Different light intensity can be received, be originally the light-intensity difference that fingerprint identification unit 21 is received be to judge finger valley and a ridge,
Paddy ridge is now caused to obscure.Particularly, the fingerprint identification unit 21 in the present embodiment selects light-sensitive device (PIN devices).Such as Fig. 5
Shown, if the light of vertical irradiation can enter into PIN devices, a photon can produce an electron hole pair.But there is certain angle
The light of degree is irradiated to after device surface, can because superficial film medium refraction index problem, have some light can occur transmitting or
Person reflects, and causes phototranstormation efficiency to reduce, and so as to the device immediately below aperture, to produce electric current big, it is more remote where produce electric current
Little, now the difference caused by paddy ridge can be therefore disturbed.Therefore, it is all provided with each fingerprint identification unit 21 in the present embodiment
Lenticule 22 is put, as shown in fig. 6, being changed into vertical irradiation to fingerprint from the direction of the light for being incident to lenticule 22 of different angles
On recognition unit 21, so that light increases, the light intensity of the light sent closer to the reflective diode of organic electroluminescence, while by Jing
The light that via 14 gets off more is evenly distributed in corresponding multiple fingerprint identification units 21, is now more beneficial for fingerprint
Paddy ridge is detected.
Wherein, the material of light shield layer 13 can also select other lightproof materials certainly using metal or black resin
Material.As shown in Figure 2, it is preferred that also including the grid of thin film transistor (TFT) 11 in light shield layer 13, that is to say, that via 14 is same with grid
Layer is arranged, therefore both can be formed using a patterning processes.It is of course also possible in any two film layer of array base palte 1
Between set up one layer have via 14 light shield layer 13.
Wherein, the size design of via 14 in the present embodiment is general 1 μm~100 μm, preferably several μm of magnitudes, via 14 and mistake
Between hole 14 spacing then farther out, such as several mm magnitudes, after such fingerprint recognition substrate 2 and array base palte 1 are fitted, each via
14 light for transmiting then can be exposed in multiple fingerprint identification units 21.It is of course also possible to according to fingerprint identification unit 21
Size is setting the aperture of via 14.
Wherein, the material and the second substrate of fingerprint recognition substrate 2 of the first substrate 10 of the array base palte 1 in the present embodiment
20 material is polyimides (PI), it is of course also possible to choose other conventional materials.
Certainly, also include being located at first substrate 10 near the pixel cell one in the contact panel of the present embodiment
Side to box substrate 3.
Embodiment 2：
The present embodiment provides a kind of display device, and it includes contact panel in embodiment 1.
Display device is due to the contact panel in embodiment 1 in the present embodiment, therefore it can preferably enter to fingerprint
Row identification.
Wherein, display device can be person's el display device, such as Electronic Paper, mobile phone, panel computer, TV
Any product with display function such as machine, display, notebook computer, DPF, navigator or part.
It is understood that embodiment of above be merely to illustrate that principle of the present utility model and adopt it is exemplary
Embodiment, but this utility model is not limited thereto.For those skilled in the art, without departing from this
In the case of the spirit and essence of utility model, various modifications and improvement can be made, these modifications and improvement are also considered as this reality
With new protection domain.
