[0038] like Figures 1 to 4 As shown, an embodiment of the first aspect of the present application provides a display panel 10, comprising: a substrate 100, comprising a driving circuit 150 and a planarization layer 160 arranged on the driving circuit 150 facing the display side of the display panel 10, and a connecting hole 161 is opened on the planarization layer 160; an isolation structure 300 layer, arranged on one side of the substrate 100, comprising an isolation structure 300 and a first defined opening 310 formed by the isolation structure 300, at least one first defined opening 310 comprising a first opening area 311 and a second opening area 312, the isolation structure 300 comprising a partition 300a located between two adjacent first defined openings 310, and the partition 300a is adjacent to the second opening area 312; a light-emitting functional layer 40, comprising a first electrode 410, at least part of which is located in the first defined opening 310, and is sequentially layered in a direction away from the substrate 100. The stacked light-emitting unit 420 and the second electrode 430, at least a portion of each of the first electrode 410, the light-emitting unit 420 and the second electrode 430 is used to constitute a sub-pixel 400; a connecting portion 411 is connected to the first electrode 410, and the connecting portion 411 is connected to the driving circuit 150 through a connecting hole 161; wherein the orthographic projection of the first electrode 410 on the substrate 100 coincides with the orthographic projection of the first opening area 311 on the substrate 100, a light-transmitting gap TG is formed between the orthographic projection of the first electrode 410 on the substrate 100 and the orthographic projection of the partition edge of the corresponding partition 300a on the substrate 100, the orthographic projection of the second opening area 312 on the substrate 100 is located within the orthographic projection of the light-transmitting gap TG on the substrate 100, and the orthographic projection of the connecting hole 161 on the substrate 100 is located on the side of the partition 300a outside the orthographic projection of the substrate 100.

[0039] A display panel 10 provided in an embodiment of the present application includes a substrate 100, an isolation structure 300 layer, a light-emitting functional layer 40 and a connecting portion 411. The substrate 100 includes a driving circuit 150 and a planarization layer 160, the driving circuit 150 is used to drive the sub-pixel 400 to emit light, and the planarization layer 160 is used to improve the flatness of the substrate 100. The connecting hole 161 is used to realize the electrical connection between the first electrode 410 and the driving circuit 150. The isolation structure 300 layer is arranged on one side of the substrate 100 and includes an isolation structure 300, and the isolation structure 300 encloses a first defined opening 310. The first defined opening 310 is used to accommodate the sub-pixel 400 to improve the problem of light interference between different sub-pixels 400. The light-emitting functional layer 40 includes a first electrode 410, a light-emitting unit 420 and a second electrode 430, and the first electrode 410 and the second electrode 430 are used to drive the light-emitting unit 420 to emit light, so as to realize the light-emitting display of the sub-pixel 400. At least one first defined opening 310 includes a first opening area 311 and a second opening area 312 that are interconnected. The orthographic projection of the first electrode 410 on the substrate 100 coincides with the orthographic projection of the first opening area 311 on the substrate 100. The first opening area 311 is used to realize the light emission of the display panel 10. A light-transmitting gap TG located within the first defined opening 310 is formed between the orthographic projection of the first electrode 410 on the substrate 100 and the orthographic projection of the partition edge of the corresponding partition 300a on the substrate 100. The orthographic projection of the second opening area 312 on the substrate 100 is located within the orthographic projection of the light-transmitting gap TG on the substrate 100, that is, the second opening area 312 is used to realize the light transmission of the display panel 10. The connecting portion 411 can realize the electrical connection between the first electrode 410 and the driving circuit 150.

[0040] In the implementation of the present application, the first opening area 311 for achieving light emission and the second opening area 312 for achieving light transmittance are interconnected, so that in the thickness direction X of the display panel 10, light can better penetrate the display panel 10 at the second opening area 312, thereby better improving the light transmittance of the display panel 10.

[0041] Due to the presence of the connecting hole 161, the planarization layer 160 forms a groove in the area where the connecting hole 161 is located. When the isolation structure 300 is disposed in the area where the connecting hole 161 is located, a groove may be formed on the isolation structure 300, affecting the shape of the isolation structure 300. In the embodiment of the present application, the connecting hole 161 and the side of the partition 300a facing the first limited opening 310 are staggered, which can improve the depression of the side of the partition 300a, ensure the shape of the first limited opening 310, and thus improve the yield of the display panel 10.

[0042] The first opening area 311 in the present application may be the isolation opening in the priority case, and the second opening area 312 in the present application may be the light-transmitting groove in the priority case.

[0043] In the present application, the sub-pixel 400 refers to an area capable of emitting light on the light-emitting functional layer 40. For example, the display panel 10 further includes a pixel definition layer, the pixel definition layer includes a pixel defining portion 200 and a pixel opening 210 formed by the pixel defining portion 200, the first electrode 410 is exposed by the pixel opening 210, at least part of the light-emitting unit 420 is located in the pixel opening 210, the second electrode 430 is located on a side of the light-emitting unit 420 away from the substrate 100, and the first electrode 410, the light-emitting unit 420, and the second electrode 430 corresponding to the area where the pixel opening 210 is located form a sub-pixel 400.

[0044] In some optional embodiments, the orthographic projection of the pixel opening 210 on the substrate 100 is located within the orthographic projection of the first limiting opening 310 on the substrate 100.

[0045] In some embodiments of the present application, the first opening area 311 and the second opening area 312 are connected, and the second opening area 312 can be formed by a surface depression of the isolation structure 300 facing the first opening area 311, that is, the second opening area 312 can be formed by a wall depression relative to the isolation structure 300 that participates in enclosing the first opening area 311. Optionally, there are many ways to set the shape of the depression of the second opening area 312. For example, the orthographic projection shape of the second opening area 312 on the substrate 100 can be polygonal, or the orthographic projection shape of the second opening area 312 on the substrate 100 can be semicircular, semi-elliptical or other arcs, which are not specifically limited in the present application. Among them, the orthographic projection of the second opening area 312 on the substrate 100 can refer to the projection area enclosed by the orthographic projection of the inner wall surface of the second opening area 312 on the substrate 100, as above, and can also refer to the area where the orthographic projection of the hollow portion on the substrate 100 is located, or the area in the defined opening that is misaligned with the orthographic projection of the pixel opening 210 on the substrate 100.

[0050] In the embodiment of the present application, a light-transmitting gap TG located within the first limited opening 310 is formed between the orthographic projection of the first electrode 410 on the substrate 100 and the orthographic projection of the edge of the corresponding partition 300a on the substrate 100, and the orthographic projection of the second opening area 312 on the substrate 100 is located within the orthographic projection of the light-transmitting gap TG on the substrate 100, that is, the second opening area 312 is used to achieve light transmission of the display panel 10.

[0051] Optionally, the light emitting unit 420 may include a hole injection layer (HIL), a hole transport layer (HTL), the light emitting unit 420, an electron injection layer (EIL) and an electron transport layer (ETL).

[0052] Optionally, the first electrode 410 and the second electrode 430 may be used as pixel electrodes of the display panel 10, wherein one of the first electrode 410 and the second electrode 430 may be used as an anode, and the other may be used as a cathode to drive the light emitting unit 420 to emit light. In the embodiment of the present application, the first electrode 410 is used as the anode of the display panel 10, and the second electrode 430 is used as the cathode of the display panel 10 for illustration.

[0053] In some optional embodiments, such as Figure 5 and Figure 6 As shown, the display panel 10 includes an encapsulation layer 500 disposed on a side of the isolation structure 300 and the sub-pixel 400 away from the substrate 100 . The encapsulation layer 500 can be used to encapsulate the sub-pixel 400 .

[0054] Optionally, the encapsulation layer 500 may include a first encapsulation layer 510 disposed on the side of the isolation structure 300 and the sub-pixel 400 away from the substrate 100, that is, the display panel 10 also includes a first encapsulation layer 510 located on the side of the second electrode 430 away from the substrate 100, and the material of the first encapsulation layer 510 may include an inorganic material, so that the first encapsulation layer 510 can have a good encapsulation ability to reduce the influence of water vapor on the sub-pixel 400. Optionally, the first encapsulation layer 510 can be prepared by a chemical vapor deposition process (chemical vapor deposition, V).

[0055] Optionally, the encapsulation layer 500 may further include a second encapsulation layer 520 disposed on the side of the first encapsulation layer 510 away from the substrate 100, and the material of the second encapsulation layer 520 may include an organic material, so that the second encapsulation layer 520 may have good fluidity, and the surface of the second encapsulation layer 520 on the side away from the substrate 100 may be relatively flat. Optionally, the second encapsulation layer 520 may be prepared by inkjet printing (IJP).

[0056] Optionally, the encapsulation layer 500 may further include a third encapsulation layer 530 disposed on the side of the second encapsulation layer 520 away from the substrate 100, the touch electrode 600 may be disposed on the side of the third encapsulation layer 530 away from the substrate 100, and the material of the third encapsulation layer 530 includes an inorganic material, so that the third encapsulation layer 530 has a good encapsulation ability to further reduce the influence of water vapor on the sub-pixel 400. Optionally, the third encapsulation layer 530 may be prepared by a chemical vapor deposition process.

[0057] In some optional embodiments, the first encapsulation layer 510 includes a first encapsulation portion 511 for encapsulating each light emitting unit 420 and the second electrode 430 , and the orthographic projection of the first limiting opening 310 on the substrate 100 is located within the orthographic projection of the first encapsulation portion 511 on the substrate 100 .

[0058] In these optional embodiments, the first encapsulation portion 511 completely covers the first defined opening 310 , so that the first encapsulation portion 511 can provide more complete protection for the sub-pixel 400 .

[0059] Optionally, the first packaging portion 511 extends from the first defined opening 310 to a side of the isolation structure 300 facing away from the substrate 100 , so as to increase the distribution area of ​​the first packaging portion 511 and improve the sealing effect of the first packaging portion 511 .

[0060] In any of the above embodiments, there are various ways to stagger the side edges of the connecting hole 161 and the partition 300a. For example, the connecting hole 161 may be located below the isolation structure 300 , or the connecting hole 161 may be located within the area where the first limiting opening 310 is located.

[0061] For example, in some optional embodiments, Figure 1 and Figure 7 As shown, the orthographic projection of the communication hole 161 on the substrate 100 is located within the orthographic projection of the partition portion 300 a on the substrate 100 .

[0062] In these optional embodiments, the connecting hole 161 is located on the side of the isolation structure 300 facing the substrate 100, so that the isolation structure 300 completely covers the connecting hole 161, and the side of the partition 300a and the connecting hole 161 are misaligned, which can also improve the uneven side of the partition 300a that affects the shape of the first limiting opening 310.

[0063] Optionally, the connecting hole 161 is spaced apart from the orthographic projection edge of the substrate 100 and the orthographic projection edge of the partition 300a on the substrate 100. This increases the distance between the projection edge of the connecting hole 161 and the projection edge of the partition 300a, and better improves the influence of the connecting hole 161 on the edge of the isolation structure 300 and the shape of the first limiting opening 310.

[0064] When the connecting hole 161 is located below the isolation structure 300 and the connecting hole 161 is completely covered by the isolation structure 300, the connecting portion 411 may extend from the first electrode 410 to below the isolation structure 300 via the second opening area 312, or the connecting portion 411 may be arranged offset from the second opening area 312. When the connecting portion 411 extends to the side of the partition 300a facing the substrate 100 via the second opening area 312, that is, when the connecting portion 411 extends to the location of the connecting hole 161 via the second opening area 312, the material of the connecting portion 411 includes a light-transmitting material to improve the influence of the connecting portion 411 on the light transmittance at the location of the second opening area 312, thereby improving the light transmittance of the display panel 10.

[0065] Alternatively, the orthographic projection of the connection portion 411 on the substrate 100 is located outside the orthographic projection of the second opening area 312 on the substrate 100, that is, the connection portion 411 and the second opening area 312 are staggered, which can also improve the influence of the connection portion 411 on the transmittance of the position where the second opening area 312 is located, thereby improving the transmittance of the display panel 10. At this time, the material of the connection portion 411 can be a light-transmitting material or a non-light-transmitting material.

[0066] When the material of the connection portion 411 includes a light-transmitting material, the material of the connection portion 411 may include at least one of indium tin oxide, indium zinc oxide, or zinc oxide, so that the connection portion 411 has good light transmittance and electrical conductivity.

[0067] In some other optional embodiments, Figure 4 As shown, the orthographic projection of the communication hole 161 on the substrate 100 is located within the orthographic projection of the first limiting opening 310 on the substrate 100 .

[0068] In these optional embodiments, the position of the connecting hole 161 corresponds to the area where the first limited opening 310 is located, so that the connecting hole 161 can be completely offset from the isolation structure 300, and it is convenient for the connecting portion 411 to be offset from the isolation structure 300. The connecting hole 161 and the connecting portion 411 can both correspond to the position of the second opening area 312, which can ensure the flatness of the planarization layer 160 in the area where the isolation structure 300 is located, thereby improving the preparation yield of the isolation structure 300.

[0069] When the communication hole 161 is located in the first defined opening 310 area, the communication hole 161 may be disposed corresponding to the first opening area 311 or the second opening area 312 .

[0070] In some optional embodiments, the orthographic projection of the communication hole 161 on the substrate 100 is located within the orthographic projection of the second opening area 312 on the substrate 100 .

[0071] In these optional embodiments, the connecting hole 161 is arranged corresponding to the second opening area 312, and the first opening area 311 is arranged corresponding to the first electrode 410. The first opening area 311 and the connecting hole 161 are staggered, so that the first electrode 410 and the connecting hole 161 are staggered, which can improve the influence of the connecting hole 161 on the shape of the first electrode 410 and improve the problem of the unevenness of the first electrode 410 affecting the light-emitting effect.

[0072] When the connecting hole 161 is set corresponding to the second opening area 312, at least part of the connecting portion 411 is set corresponding to the second opening area 312.

[0117] Optionally, as described above, at least some of the connecting holes 161 may be arranged at intervals along a straight line in the arrangement direction of the sub-pixels 400. For example, the connecting holes 161 may be arranged at intervals along a straight line in the first direction Y and / or the second direction Z, so as to arrange the connecting holes 161 below the isolation structure 300 so that the edge portion of the isolation structure 300 facing the first limiting opening 310 is not easily affected by the arrangement of the connecting holes 161 and becomes concave.

[0118] like Fig.12 As shown, optionally, the pixel defining portion 200 is provided with a receiving groove 220, and the isolation structure 300 may be at least partially located in the receiving groove 220, so that the isolation structure 300 is less likely to have an excessively large height compared to the substrate 100, thereby being able to better reduce the thickness of the display panel 10.
