Site preparation description, it is clear that the described embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Based on this
Embodiment in invention, every other reality obtained by those of ordinary skill in the art without making creative efforts
Example is applied, shall fall within the protection scope of the present invention.
In the conceived case, the same or similar part that the various pieces in attached drawing are mentioned will use identical attached drawing
Label.
Fig. 1 is the schematic diagram of display panel according to an embodiment of the invention.
As shown in Figure 1, display panel may include: substrate layer 3 and the detection luminescent layer 2 positioned at 3 the same side of substrate layer
With thin-film encapsulation layer 1.Detecting luminescent layer 2 may include at least one mark group, and each mark group includes continuous along preset direction
Multiple luminescence units of arrangement.In the particular embodiment, preset direction is along the boundary perpendicular to substrate layer 3 and towards film
The direction 4 on the boundary of encapsulated layer 1 is illustrated, and is not limited this.1 part of thin-film encapsulation layer covers at least one mark group.
For example, thin-film encapsulation layer 1 covers orthographic projection of multiple luminescence units on substrate layer 3 in the orthographic projection part on substrate layer 3.
Specifically, the display screen of display panel may include the thin-film encapsulation layer 1 being stacked, detection luminescent layer 2 and base
Material layer 3.Herein, thin-film encapsulation layer 1 and detection luminescent layer 2 can be and directly contact, and certainly, not influence to distinguish detection hair
In the case where the luminescence imaging of photosphere 2, detect luminescent layer 2 and substrate layer 3 be also possible between be additionally provided with other functional layers,
Detect luminescent layer 2 vapor deposition can the vapor deposition that carries out of any operation stage before thin-film package, here for thin-film package
Positional relationship between layer 1 and detection luminescent layer 2 is without limitation.For example, luminescent layer 2 can (pixel be shown in the region AA for detection
Region) vapor deposition when be deposited together, i.e. detection luminescent layer 2 can be one layer of picture element display area.Similarly, luminescent layer 2 is detected
Can be with substrate layer 3 and directly contact, be also possible between be additionally provided with other functional layers, here to detection luminescent layer 2 He
Positional relationship between substrate layer 3 is also without limitation.
Luminescent layer 2 is detected, can be the film layer for absorbing energy under shooting condition and converting the energy to light radiation.?
Here, detection luminescent layer 2 can be made of luminescent material.Specifically, which can be phosphor, for example,
The sulfide etc. of alkaline-earth metal；The luminescent material may be luminous organic material, for example, oxadiazoles and its derivative species, three
Azoles and its derivative species etc., here without limitation for the specific type of luminescent material.In order to ensure display panel has flexibility,
The luminescent material can be preferably luminous organic material, so that detection luminescent layer 2 can be with scatter display panel in bending
Part stress.For excitation-detection luminescent layer 2 shine condition, can be light, high energy particle, external electric field etc., here for
Specific shooting condition is without limitation.
Specifically, since detection luminescent layer 2 can be used for detecting the first boundary 11 and theoretical encapsulation side of thin-film encapsulation layer 1
Therefore the drift condition on boundary detects luminescent layer 2 and thin-film encapsulation layer 1 may exist overlapping region and Non-overlapping Domain, i.e. film
Encapsulated layer 1 can partially cover detection luminescent layer 2.Again in other words, it can be positive throwing of the thin-film encapsulation layer 1 on substrate layer 3
Shadow part covers orthographic projection of multiple luminescence units on substrate layer 3 of mark group, wherein overlapping region can D as shown in figure 1
Shown in region, underlapped region can be shown in the region C as shown in figure 1.Further, it is excited when under preset shooting condition
When detecting 2 luminescence imaging of luminescent layer, user is observed that the luminous intensity of the detection luminescent layer 2 in the region C and the detection in the region D
The luminous intensity of luminescent layer 2 is different, and then user can be concluded that the position on the first boundary 11 of thin-film encapsulation layer 1, may be used also
To conclude the lap position on the first boundary 11 with the mark group in detection luminescent layer 2.
Specifically, water oxygen may not contacted by the region that thin-film encapsulation layer 1 encapsulates, in turn results in failure, to make
It is low to obtain the region light emission luminance not encapsulated by thin-film encapsulation layer 1.
About the type of substrate layer 3, it can be glass baseplate, flexible parent metal etc., the type of substrate layer 3 is not done here
It is specific to limit.
It should be appreciated that multiple luminescence units of mark group are contact arrangements each other, i.e., mark group is by along pre-
The continuously arranged multiple luminescence units of set direction are constituted.
In addition to this, it is also understood that the luminescent color of multiple luminescence units can be same, or at least three
A different colours.Further, when multiple luminescence units are made of the luminescence unit of at least three kinds luminescent colors, luminescence unit
Arrangement be it is regular, the luminescence unit of different colours is arranged in that same order, such as RGBRGBRGB ....Herein, when
When the luminescent color of multiple luminescence units of mark group is same color, it may not connect by the region that thin-film encapsulation layer 1 encapsulates
Water oxygen is touched, failure is in turn resulted in, so that the region light emission luminance not encapsulated by thin-film encapsulation layer 1 is low, it can be according to more
The difference of a luminescence unit light emission luminance encapsulates the position on boundary to distinguish；When the luminescent color of multiple luminescence units of mark group
It, can be according to number and dimensions judgement the encapsulation boundary of luminescence unit in packaging area when being at least three kinds of colors.
For ease of description, two adjacent luminescence units the first luminescence unit 21 can be referred to as to shine with second
Unit 22.Herein, the first luminescence unit 21 can use different luminescent materials from the second luminescence unit 22, so that the
One luminescence unit 21 can be different from the luminescent color of the second luminescence unit 22；Identical luminescent material can also be used, so that
First luminescence unit 21 is identical as the luminescent color of the second luminescence unit 22.About the first luminescence unit 21 and the second luminescence unit
22 shape and size specification, the first luminescence unit 21 can be identical with shape with the second luminescence unit 22, such as can be circle
Shape or rectangle etc.；First luminescence unit 21 can also be with shape difference with the second luminescence unit 22, such as one is circle, another
For rectangle, here for the first luminescence unit 21 and the second luminescence unit 22 shape without limitation.When the first luminescence unit 21
When identical with 22 shape of the second luminescence unit, the size rule of the first luminescence unit 21 and the second luminescence unit 22 can be identical,
It can also be different, here also without limitation to this.
It should be appreciated that the precision of the spacing between the first boundary 11 and the second boundary 31 and these lists that shine of mark group
The dimensions of member is related, when the size of luminescence unit is smaller, the essence of the spacing between the first boundary 11 and the second boundary 31
Accuracy is higher.
Detection luminescent layer 2 is arranged in the embodiment of the present invention on a display panel, passes through the luminescence unit in detection luminescent layer 2
