[0002] An encapsulation layer for isolating moisture and oxygen is provided on the display panel. In the border area of the display panel, the encapsulation layer usually includes two inorganic encapsulation layers stacked on top of each other.

[0003] However, in the related art, the sealing performance of the encapsulation layer in the border area needs to be improved. Summary of the Invention

[0004] The main technical problem to be solved by this application is to provide a display panel, which reduces the probability of delamination between the encapsulation layers in the border area of the display panel and reduces the probability of problems such as bubbling and black spots on the display panel.

[0005] To solve the above technical problem, a technical solution adopted by this application is: to provide a display panel having a display area and a non-display area, the display panel includes a substrate, a partition portion, and an encapsulation layer. The partition portion is located in the non-display area and is disposed on one side of the substrate; the encapsulation layer is located on the side of the substrate where the partition portion is provided, and the encapsulation layer covers the partition portion and the substrate. Wherein, the encapsulation layer includes a first inorganic layer and a second inorganic layer stacked on top of each other. The first inorganic layer includes a first magnetic attraction portion, and the second inorganic layer includes a second magnetic attraction portion. The orthographic projection of the first magnetic attraction portion on the substrate at least partially overlaps with the orthographic projection of the second magnetic attraction portion on the substrate, and the polarities of the first magnetic attraction portion and the second magnetic attraction portion are opposite.

[0006] Preferably, at least a part of the overlapping portion of the orthographic projection of the first magnetic attraction portion on the substrate and the orthographic projection of the second magnetic attraction portion on the substrate is located on the side of the partition portion away from the display area. So that the position where the probability of delamination between the first inorganic layer and the second inorganic layer is relatively large has a strong adhesion force and is not easily delaminated.

[0007] Preferably, the orthographic projection of the first magnetic attraction portion on the substrate and the orthographic projection of the second magnetic attraction portion on the substrate are both located on the side of the partition portion away from the display area. It is possible to further reduce the amount of magnetic attraction material in the two magnetic attraction portions, reduce costs, and avoid interfering with the normal display of the display area.

[0009] Preferably, the first magnetic attraction part is located on the side of the first inorganic layer close to the second inorganic layer; and / or, the second magnetic attraction part is located on the side of the second inorganic layer close to the first inorganic layer. Since only part of the inorganic layer is doped with magnetic particles in the thickness direction, the encapsulation ability of the inorganic layer is ensured; and the two magnetic attraction parts are close to each other in the thickness direction, improving the adsorption force between the first inorganic layer and the second inorganic layer.

[0010] Preferably, corrosion-resistant particles are doped in the first main layer, and / or the second main layer. The corrosion-resistant particles can increase the corrosion resistance and oxidation resistance of the encapsulation layer, thereby improving its encapsulation performance. Since the encapsulation layer has strong encapsulation performance, the width of the encapsulation layer in the border area can be reduced, thus realizing a narrow border of the display panel.

[0011] Preferably, the corrosion-resistant particles are located in the first magnetic attraction part, and / or the second magnetic attraction part. The corrosion-resistant particles can be doped synchronously with the magnetic particles, reducing the complexity of the manufacturing process, and the corrosion-resistant particles do not affect the magnetism of the magnetic particles.

[0012] Preferably, in the length direction of the encapsulation layer, the length of the overlapping part of the orthographic projection of the first magnetic attraction part on the substrate and the orthographic projection of the second magnetic attraction part on the substrate is 110 μm - 130 μm. In this width range, sufficient adsorption force between the first inorganic layer and the second inorganic layer can be ensured, and the encapsulation performance of the encapsulation layer can be ensured.

[0013] Preferably, the doping ratio of the first magnetic particles in the first magnetic attraction part is 50% - 100%; and / or, the doping ratio of the second magnetic particles in the second magnetic attraction part is 50% - 100%. In this range, the adsorption force between the first inorganic layer and the second inorganic layer is ensured.

[0014] Preferably, the doping ratio of the corrosion-resistant particles is 1.5 - 2.5 times the doping ratio of the first magnetic particles and / or the second magnetic particles. To ensure the corrosion resistance of the encapsulation layer.

[0015] To solve the above technical problems, another technical solution adopted by this application is: to provide a manufacturing method of a display panel, including: forming an isolation part on a substrate; forming a first main layer on the side of the substrate where the isolation part is provided, wherein the first inorganic layer covers the isolation part and the substrate; doping first magnetic particles in the first main layer to form a first magnetic attraction part; laminating and forming a second main layer on the side of the first main layer facing away from the substrate; doping second magnetic particles in the second main layer to form a second magnetic attraction part; wherein, the orthographic projection of the first magnetic attraction part on the substrate at least partially overlaps with the orthographic projection of the second magnetic attraction part on the substrate and the polarities of the first magnetic attraction part and the second magnetic attraction part are opposite.

[0016] Preferably, before the step of laminating and forming a second main layer on the side of the first main layer facing away from the substrate, it further includes: doping corrosion-resistant particles in the first main layer; and / or after the step of laminating and forming a second main layer on the side of the first main layer facing away from the substrate, it further includes: doping corrosion-resistant particles in the second main layer. The corrosion-resistant particles and the magnetic particles are doped synchronously, reducing the complexity of the manufacturing steps, and the corrosion-resistant particles do not affect the magnetism of the magnetic particles.

[0017] To solve the above technical problems, another technical solution adopted by this application is: to provide a display device, including the display panel according to any one of the embodiments.

[0018] The beneficial effects of this application are: Different from the prior art, the display panel and the display device provided by this application respectively set two magnetic attraction parts with different polarities in two inorganic layers in the encapsulation layer. By the mutual attraction of the two magnetic attraction parts, the adhesion force between the two inorganic layers is improved, making the two inorganic layers fit tightly, reducing the probability of peeling and breakage of the two inorganic layers at high temperature, thereby reducing the probability of generating bubbles on the display panel, and avoiding the problem of water vapor invading into the screen body and generating black spots. Moreover, the manufacturing method of the display panel provided by this application does not increase the thickness of the inorganic layer by doping magnetic particles. This method is simple and effective, and there is no need to adjust the light-emitting layer, reducing costs. Description of the Drawings

[0027] To make the purpose, technical solutions and effects of the present application clearer and more definite, the following further describes the present application in detail with reference to the accompanying drawings and by way of examples. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0028] The inventors have found through long-term research that at high temperatures, the existing display panel is prone to peeling between two inorganic encapsulation layers in the border area, resulting in bubbling defects in the display panel, thereby causing water vapor to invade the display area from between the inorganic encapsulation layers and forming black spots and other problems on the display panel.

[0029] To solve the above problems, the present application provides a display panel, its manufacturing method, and a display device, which will be introduced in detail below.

[0030] Refer to Figure 1 , Figure 1 It is a schematic structural diagram of the first embodiment of the display panel of the present application. The display panel has a display area AA and a non-display area AB, where the border area of the display panel is located in the non-display area AB. In the non-display area AB, specifically, it can be the border area. The display panel includes a substrate 1, a spacer 2, and an encapsulation layer 3; the spacer 2 is disposed on one side of the substrate 1; the encapsulation layer 3 is located on the side of the substrate 1 where the spacer 2 is provided, and the encapsulation layer 3 covers the spacer 2 and the substrate 1; wherein, the encapsulation layer 3 includes a first inorganic layer 31 and a second inorganic layer 32 stacked, the first inorganic layer 31 includes a first magnetic attraction part 311, the second inorganic layer 32 includes a second magnetic attraction part 321, the orthographic projection of the first magnetic attraction part 311 on the substrate 1 at least partially overlaps with the orthographic projection of the second magnetic attraction part 321 on the substrate 1, and the polarities of the first magnetic attraction part 311 and the second magnetic attraction part 321 are opposite.

[0031] Specifically, in the border area of the display panel, the display panel includes an isolation part 2 and a packaging layer 3 provided on a substrate 1. The packaging layer 3 covers the surface of the display panel to prevent moisture, oxygen, etc. from the outside of the display panel from invading the display area AA. The isolation part 2 is used to block the overflow of the organic layer (not shown in the figure) in the packaging layer 3 and communicate with the outside of the display panel, thereby improving the packaging effect. The packaging layer 3 in the border area includes a first inorganic layer 31 and a second inorganic layer 32 arranged in two layers. In the display panel provided in this application, first magnetic attraction parts 311 and second magnetic attraction parts 321 with different polarities are respectively arranged in the first inorganic layer 31 and the second inorganic layer 32 of the packaging layer 3. Since the orthographic projections of the first magnetic attraction part 311 and the second magnetic attraction part 321 on the substrate 1 have an overlapping part, there is a magnetic attraction force between the first magnetic attraction part 311 and the second magnetic attraction part 321, so that the first inorganic layer 31 and the second inorganic layer 32 attract each other to improve the adhesion force between the two inorganic layers, making the two inorganic layers fit tightly, reducing the probability of peeling and damage of the two inorganic layers at high temperature, thereby reducing the probability of bubbling and damage on the border area of the display panel, and avoiding the problem of moisture invading into the screen body and generating black spots.

[0032] In this embodiment, both the first magnetic attraction part 311 and the second magnetic attraction part 321 cover the isolation part 2. In other embodiments, the first magnetic attraction part 311 and / or the second magnetic attraction part 321 may not cover or partially cover the isolation part 2. The orthographic projection of the first magnetic attraction part 311 on the substrate 1 is located within the orthographic projection of the second magnetic attraction part 321 on the substrate 1, or the orthographic projection of a part of the first magnetic attraction part 311 on the substrate 1 may also be located outside the second magnetic attraction part 321, or the orthographic projection of the second magnetic attraction part 321 on the substrate 1 is located within the orthographic projection of the first magnetic attraction part 311 on the substrate 1.

[0033] It can be understood that the packaging layer 3 extends from the border area to the display area AA.

[0034] Optionally, the isolation part 2 on the substrate 1 may be provided with one isolation member or multiple isolation members. Refer to Figure 2 and Figure 3 , Figure 2 is a schematic structural diagram of the second embodiment of the display panel of this application, Figure 3 is a schematic structural diagram of the third embodiment of the display panel of this application. In the second embodiment and the third embodiment, the isolation part 2 includes a first isolation member 21 and a second isolation member 22, and the second isolation member 22 is arranged on the side of the first isolation member 21 away from the display area AA. As shown in Figure 2 in the second embodiment shown, the first magnetic attraction part 311 and the second magnetic attraction part 321 cover the second isolation member 22 and a part of the first isolation member 21. Of course, it can also be as shown in Figure 3In the third embodiment shown, the first magnetic attraction portion 311 and the second magnetic attraction portion 321 only cover the second spacer 22. This can avoid the first magnetic attraction portion 311 and the second magnetic attraction portion 321 from interfering with the normal display of the display area AA, and can also reduce the usage amount of the magnetic attraction material and lower the cost.

[0035] Optionally, continue to refer to Figure 2 and Figure 3 , a touch layer 4 may further be provided on the side of the encapsulation layer 3 away from the substrate 1. The touch layer 4 may be made of an inorganic material to further improve the encapsulation effect.

[0036] Refer to Figure 4 , Figure 4 FIG. is a schematic structural diagram of the fourth embodiment of the display panel of the present application. In this embodiment, at least a part of the overlapping portion of the orthographic projection of the first magnetic attraction portion 311 on the substrate 1 and the orthographic projection of the second magnetic attraction portion 321 on the substrate 1 is located on the side of the spacer 2 away from the display area AA. It can be understood that at least a part of this overlapping portion is located on the side of the orthographic projection of the spacer 2 on the substrate 1 away from the display area AA. Optionally, at least a part of the overlapping portion of the orthographic projection of the first magnetic attraction portion 311 on the substrate 1 and the orthographic projection of the second magnetic attraction portion 321 on the substrate 1 is located on the side of the orthographic projection of the second spacer 22 on the substrate 1 away from the display area AA. Since there is a strong attraction between the overlapping first magnetic attraction portion 311 and the second magnetic attraction portion 321, and the probability of peeling of the encapsulation layer 3 on the side of the spacer 2 away from the display area AA is the greatest, this attraction makes the adhesion force between the side of the first inorganic layer 31 away from the display area AA and the side of the second inorganic layer 32 away from the display area AA strong and not easy to peel. Further, the orthographic projection of the first magnetic attraction portion 311 on the substrate 1 and the orthographic projection of the second magnetic attraction portion 321 on the substrate 1 are both located on the side of the spacer 2 away from the display area AA. Since the length of the encapsulation layer 3 on the side of the spacer 2 away from the display area AA is limited, the foregoing technical solution can further reduce the usage amount of the magnetic attraction material in the magnetic attraction portion, lower the cost, and avoid interfering with the normal display of the display area AA.

[0037] Optionally, refer to Figure 5 , Figure 5It is a partial structural schematic diagram of the fifth embodiment of the display panel of the present application. The first inorganic layer 31 includes a first main layer 31a and first magnetic particles 31b doped in the first main layer 31a; wherein, the first main layer 31a doped with the first magnetic particles 31b forms a first magnetic attraction part 311; the second inorganic layer 32 includes a second main layer 32a and second magnetic particles 32b doped in the second main layer 32a; wherein, the second main layer 32a doped with the second magnetic particles 32b forms a second magnetic attraction part 321, and the first magnetic particles 31b and the second magnetic particles 32b have opposite polarities. Specifically, the first magnetic particles 31b and the second magnetic particles 32b can be made of magnetizable materials. For example, both of them can be made of materials such as ferrite, NdFeB magnet or SmCo magnet. The magnetizable materials can be magnetized separately before doping, so that the first magnetic particles 31b and the second magnetic particles 32b have opposite polarities, and an attraction force is formed between the first magnetic attraction part 311 and the second magnetic attraction part 321 formed after doping; or one is made of materials such as ferrite, NdFeB magnet or SmCo magnet, and the other is made of a metal material that can be attracted by the former. The materials such as ferrite, NdFeB magnet or SmCo magnet can be magnetized before doping to make them have polarities. After doping, one of the magnetic attraction parts has a polarity, and the magnetizable materials in the other magnetic attraction part are magnetized, so that an attraction force is formed between the first magnetic attraction part 311 and the second magnetic attraction part 321. The first main layer 31a and the second main layer 32a can be made of ceramic materials such as oxides, fluorides, silicon nitride, etc. deposited by vapor deposition.

[0038] Optionally, continue to refer to Figure 5 , the first magnetic attraction part 311 is located on the side of the first inorganic layer 31 close to the second inorganic layer 32; and / or, the second magnetic attraction part 321 is located on the side of the second inorganic layer 32 close to the first inorganic layer 31. Specifically, the thickness h11 of the first magnetic attraction part 311 can be 1 / 2 of the thickness h1 of the first inorganic layer 31; and / or, the thickness h21 of the second magnetic attraction part 321 can be 1 / 2 of the thickness h2 of the second inorganic layer 32. Since only part of the inorganic layer is doped with magnetic particles in the thickness direction, the encapsulation ability of the inorganic layer is ensured; and the two magnetic attraction parts are close to each other in the thickness direction, improving the adsorption force between the first inorganic layer 31 and the second inorganic layer 32.

[0039] Optionally, corrosion-resistant particles (not shown in the figure) are doped in the first main layer 31a and / or the second main layer 32a. The corrosion-resistant particles can increase the corrosion resistance and oxidation resistance of the encapsulation layer 3, thereby improving its encapsulation performance. Since the encapsulation layer 3 has strong encapsulation performance, the width of the encapsulation layer 3 located in the border area can be reduced, thereby realizing a narrow border of the display panel.

[0040] Optionally, the corrosion-resistant particles are located in the first magnetic attraction part 311 and / or the second magnetic attraction part 321. The corrosion-resistant particles can be doped synchronously with the first magnetic particles 31b and / or the second magnetic particles 32b, reducing the complexity of the manufacturing steps, and the corrosion-resistant particles do not affect the magnetism in the first magnetic particles 31b and / or the second magnetic particles 32b. Specifically, the material of the corrosion-resistant particles can be graphene or the like.

[0041] Continue to refer to Figure 4 , in the length direction of the encapsulation layer 3 (such as Figure 4 the X direction in Figure 6 ), the length d of the overlapping part of the orthographic projection of the first magnetic attraction part 311 on the substrate 1 and the orthographic projection of the second magnetic attraction part 321 on the substrate 1 is 110 μm - 130 μm. Specifically, the length d of the overlapping part of the orthographic projection of the first magnetic attraction part 311 on the substrate 1 and the orthographic projection of the second magnetic attraction part 321 on the substrate 1 can be 120 μm. At this width, sufficient adsorption force between the first inorganic layer 31 and the second inorganic layer 32 in the encapsulation layer 3 can be ensured, and the encapsulation performance of the encapsulation layer 3 can be ensured. Further, refer to Figure 6 , Figure 6 is a schematic structural diagram of the sixth embodiment of the display panel of the present application. In the length direction of the encapsulation layer 3 (such as

[0042] the X direction in

[0043] ), the lengths of the orthographic projections of the first magnetic attraction part 311 and the second magnetic attraction part 321 on the substrate 1 are both d, and the two completely overlap, further ensuring that the encapsulation layer 3 has sufficient adsorption force and encapsulation performance at the minimum length.

[0044] Specifically, the doping ratio of the first magnetic particles 31b in the first magnetic attraction part 311 is 50% - 100%; and / or the doping ratio of the second magnetic particles 32b in the second magnetic attraction part 321 is 50% - 100%. Within this range, the adsorption force between the first inorganic layer 31 and the second inorganic layer 32 is ensured. Figure 7 、 Figures 8a - 8e Figure 7 is a schematic flow diagram of the first embodiment of the manufacturing method of the display panel of the present application. Figures 8a - 8e is a schematic structural diagram of each step of the first embodiment of the manufacturing method of the display panel of the present application. The manufacturing method of the display panel includes:​

[0045] Step S101: forming an isolation portion 2 on a substrate 1. Figure 8a As shown, the isolation part 2 may include one isolation member or multiple isolation members. The isolation member may be made of optical adhesive, and the patterned isolation part 2 may be formed through an exposure step.

[0046] Step S102: forming a first main body layer 31a on the side of the substrate 1 where the isolation portion 2 is provided, wherein the first main body layer 31a covers the isolation portion 2 and the substrate 1. Figure 8b As shown, the first main layer 31 a can be formed by vapor-depositing oxide, fluoride, silicon nitride or other materials on the isolation part 2 and the substrate 1 to form a ceramic film, and the thickness of the first main layer 31 a can be 1 μm.

[0047] Step S103: doping the first magnetic particles 31b into the first main layer 31a to form the first magnetic attraction portion 311. Figure 8c As shown, after forming the first main body layer 31a, the first magnetic particles 31b are doped in the first main body layer 31a, and the first magnetic attraction portion 311 is formed without increasing the thickness of the first main body layer 31a and without affecting the structure of the first main body layer 31a. Optionally, the first magnetic attraction portion 311 can be arranged on the side of the isolation portion 2 away from the display area AA.

[0048] Step S104: The first main body layer 31a is stacked on the side away from the substrate 1 to form a second main body layer 32a. Figure 8d As shown, a ceramic film may be formed by vapor-depositing oxide, fluoride, silicon nitride or other materials on the first main layer 31a to form a second main layer 32a covering the first main layer 31a. The thickness of the second main layer 32a may be 1 μm.

[0049] Step S105: doping the second magnetic particles 32b in the second main layer 32a to form a second magnetic attraction portion 321; wherein the orthographic projection of the first magnetic attraction portion 311 on the substrate 1 and the orthographic projection of the second magnetic attraction portion 321 on the substrate 1 at least partially overlap, and the polarities of the first magnetic attraction portion 311 and the second magnetic attraction portion 321 are opposite, such as Figure 8e As shown. Optionally, the second magnetic attraction portion 321 can be arranged on the side of the isolation portion 2 away from the display area AA. Specifically, the first magnetic particles 31b and the second magnetic particles 32b can be pre-magnetized before doping, or one can be pre-magnetized before doping and the other can be magnetized by the pre-magnetized magnetic particles after doping, thereby generating an attractive force between the first magnetic attraction portion 311 and the second magnetic attraction portion 321. This method can achieve close fitting of the inorganic layer in the encapsulation layer 3 without major adjustments, is simple and effective, simplifies the process, and reduces costs.

[0050] Optionally, before step S104, it further includes: doping corrosion-resistant particles in the first main body layer 31a, and further, the corrosion-resistant particles are located in the first magnetic attraction part 311; and / or, after step S104, it further includes: doping corrosion-resistant particles in the second main body layer 32a, and further, the corrosion-resistant particles are located in the second magnetic attraction part 321. The corrosion-resistant particles can be doped only in one inorganic layer or in two inorganic layers, and the corrosion-resistant particles can be doped synchronously with the first magnetic particles 31b and / or the second magnetic particles 32b, which can further improve the manufacturing efficiency, enhance the encapsulation performance of the display panel, and facilitate the realization of a narrow border of the display panel.

[0051] The present application also provides a display device, including the display panel described in any one of the foregoing embodiments. The display device can be a mobile phone, a tablet computer, a smart wearable device such as a smart watch, etc.
