[0009] First chemical vapor deposition (CVD) layer;

[0010] Second CVD;

[0011] The self-healing layer is located between the first CVD and the second CVD. The self-healing layer is composed of a self-healing organic material or a self-healing hybrid material. The self-healing organic material is an organic material with a self-initiated polymerization molecular chain repair reaction. The self-healing hybrid material is obtained by mixing the self-healing organic material and an inorganic material with a first characteristic, the first characteristic including at least one of the following: lattice recrystallization; phase change self-healing reaction.

[0012] In some embodiments, the encapsulation layer further includes:

[0013] At least one dam structure, a portion of which is located between the first CVD and the self-healing layer, and another portion of which is located between the self-healing layer and the second CVD, wherein the dam structure is made of a semi-fluid material.

[0014] In some embodiments, the projections of one portion of the dam structure and the other portion of the dam structure in the self-healing layer are staggered.

[0018] Inorganic water and oxygen barrier layer;

[0019] A glass layer or a ceramic layer, wherein the inorganic water and oxygen barrier layer is located between the semiconductor circuit layer and the glass layer or the ceramic layer.

[0020] In some embodiments, an adhesive is provided at the edge region of the glass layer or the ceramic layer, and the glass layer or the ceramic layer is bonded to the inorganic water and oxygen barrier layer by the adhesive.

[0021] In some embodiments, the glass layer is an ultrathin glass (UTG) layer.

[0022] Secondly, embodiments of this application propose a display module, including a cover plate and the display panel described in the first aspect, wherein the touch layer is located between the cover plate and the light-emitting layer.

Detailed Implementation

[0042] The embodiments of this application will now be described in detail. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0043] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0044] The display template and display module according to embodiments of this application are described below with reference to the accompanying drawings.

[0045] like Figure 1 As shown, this application embodiment provides a display panel 100, including:

[0046] Touch layer 101;

[0047] Light-emitting layer 102;

[0048] Encapsulation layer 103 is located between touch layer 101 and light-emitting layer 102, and encapsulation layer 103 includes:

[0049] First chemical vapor deposition (CVD) layer 1031;

[0050] Second CVD 1033;

[0051] Self-healing layer 1032 is located between the first CVD 1031 and the second CVD 1033. Self-healing layer 1032 is composed of self-healing organic material or self-healing hybrid material. Self-healing organic material is an organic material with self-initiated polymerization molecular chain repair reaction. Self-healing hybrid material is obtained by mixing self-healing organic material with inorganic material with a first characteristic. The first characteristic includes at least one of the following: lattice recrystallization; phase change self-healing reaction.

[0052] As an example, both the first CVD1031 and the second CVD1032 in this embodiment can be inorganic chemical vapor deposition layers.

[0053] It should be understood that the touch layer 101 (i.e., the Touch Panel (TP) layer, also known as the touch function layer) can be used to detect user touch input, etc., the emissive layer 102 (EL) can be used for light emission and display, and is responsible for displaying content. The encapsulation layer 103 (Thin Film Encapsulation, TFE) can be used to protect the emissive layer 102, etc., reduce the corrosion of the emissive layer 102 in the display panel by the external environment, and improve the life of the display panel. The first CVD 1031 layer is a protective layer that can isolate the external environment from the self-healing layer 1032, prevent moisture and air from penetrating, prevent the self-healing layer 1032 and the emissive layer 102 from environmental corrosion, and protect the self-healing layer 1032 and the emissive layer 102, etc. The second CVD 1033 is another protective layer that further prevents moisture and air from penetrating, and enhances the protection of the self-healing layer 1032 and the emissive layer 102 in the display panel 100. In addition, in this embodiment, a self-healing layer 1032 is provided in the display panel 100. The self-healing layer 1032 is composed of a self-healing organic material with a self-initiated polymerization molecular chain repair reaction, or is composed of a self-healing hybrid material obtained by mixing an organic material with a self-initiated polymerization molecular chain repair reaction with an inorganic material with a lattice recrystallization and / or phase change self-healing reaction. Therefore, the self-healing layer 1032 has a self-healing function, is not easy to break, and can better resist impact. As an example, the self-healing layer 1032 can be formed by multiple precision vapor deposition / evaporation / printing methods.

[0054] In the embodiments of this application, since the organic material with self-initiated polymer chain repair reaction or the mixed material obtained by mixing the organic material with self-initiated polymer chain repair reaction and the inorganic material with lattice recrystallization and / or phase change self-repair reaction can better absorb impact force, deform after being subjected to force, and can better recover the deformation after the external force disappears, it has good impact resistance. By setting the self-repairing layer 1032 made of this material, the display panel 100 can improve its impact resistance.

[0055] like Figure 2 As shown, in some embodiments, the encapsulation layer 103 further includes:

[0056] At least one dam structure 104, a portion of the dam structure 104 is located between the first CVD 1031 and the self-healing layer 1032, and another portion of the dam structure 104 is located between the self-healing layer 1032 and the second CVD 1033, the dam structure 104 being made of a semi-fluid material.

[0057] In this embodiment, the display panel 100 is provided with a dam structure 104, which is embedded between the self-healing layer 1032, the first CVD 1031, and the second CVD 1033. For example, at least one part of the dam structure 104 is embedded between the first CVD 1031 and the self-healing layer 1032, and another part of the dam structure 104 is embedded between the self-healing layer 1032 and the second CVD 1033. Each dam structure 104 is made of a semi-fluid material and has a self-healing function. The semi-fluid material of the dam structure is compatible and has strong bonding with the first CVD1031 and the second CVD1033. Thus, if the first CVD1031 and the second CVD1033 are damaged by stress and cracks appear, the self-healing material of the dam structure can flow and fill the cracks in the first CVD1031 and the second CVD1033, and gradually repair them through molecular bonding with the outer layer material (for example, part of the dam structure 104 is with the first CVD1031, and another part is with the second CVD1033), thereby achieving a self-healing effect. In addition, the self-healing material of the dam structure itself can absorb and resist some of the impact force, further improving the impact resistance of the display panel.

[0058] In some embodiments, a portion of the cofferdam structure 104 and another portion of the cofferdam structure are interleaved in the projection of the self-healing layer 1032.

[0059] Since one part of the dam structure 104 and another part of the dam structure 104 are located in different layers, one part of the dam structure 104 is located between the first CVD 1031 and the self-healing layer 1032, and the other part of the dam structure 104 is located between the self-healing layer 1032 and the second CVD 1033, in order to avoid the influence between the dam structures 104 in the self-healing layer 1032, the projections of one part of the dam structure 104 and the other part of the dam structure 104 in the self-healing layer 1032 are staggered, that is, the dam structures are staggered. The self-healing material of the staggered dam structure can absorb and resist some of the impact force, improve the impact resistance of the display panel, and the staggered dam structure can improve the buffering performance.

[0060] like Figure 2 As shown, in some embodiments, the display panel 100 further includes:

[0061] Semiconductor circuit layer 106;

[0062] The substrate layer 107 and the semiconductor circuit layer 106 are located between the light-emitting layer 102 and the substrate layer 107. The substrate layer 107 includes:

[0063] Inorganic water and oxygen barrier layer 1071;

[0064] A glass or ceramic layer 1072 and an inorganic water and oxygen barrier layer 1071 are located between the semiconductor circuit layer 106 and the glass or ceramic layer.

[0065] The semiconductor circuit layer 106 (array) can be used to control the current of pixels, drive the switching state of pixels (display driving), and perform signal processing. The substrate layer 107 can be used for support, for example, to directly support the semiconductor circuit layer 106, the light-emitting layer 102, etc., thereby indirectly supporting the encapsulation layer 103 and the touch layer 101, etc. In this embodiment, the substrate layer 107 includes an inorganic water and oxygen barrier layer 1071 and a glass layer or ceramic layer 1072. The inorganic water and oxygen barrier layer 1071 can be used to block water and oxygen and to support the semiconductor circuit layer 106. The glass layer or ceramic layer 1072 is used for support, for example, to support the above layers in the display panel. Since glass and ceramic have high modulus, a single glass layer or ceramic layer 1072 can provide a good support effect, and the support effect of a single glass layer or ceramic layer 1072 is better than that of two PI layers. In this embodiment, the substrate 107 is improved to a two-layer structure consisting of an inorganic water and oxygen barrier layer 1071 and a glass layer (ceramic layer). Compared to related technologies that use at least two layers of Pi, an inorganic water and oxygen barrier layer 1071, and a polyethylene terephthalate (PET) layer (which has a larger thickness, lower modulus, and weaker rigidity), this improves both modulus and rigidity while reducing thickness, thus meeting the requirements of a thin and light design. As an example, the glass or ceramic can be cut using a high-precision alignment and low-energy, high-precision laser cutting process.

[0066] In this embodiment, the substrate 107 is improved to a structure of inorganic water and oxygen barrier layer 1071 + glass layer (ceramic layer). While reducing the thickness, the modulus and rigidity of the substrate 107 are improved, which can reduce the occurrence of display panel deformation failure under stress. By adjusting the thickness of the glass layer or ceramic layer 1072 in the substrate 107, various application scenarios of foldable and candybar phones can be met.

[0067] In some embodiments, the glass layer is an ultrathin glass UTG layer.

[0068] Due to its ultra-thin properties, the UTG layer not only meets the requirements for lightweight and thin designs, but also has high light transmittance to ensure display quality. Furthermore, its overall weight, strength, and impact resistance effectively protect the display panel from external impacts and scratches. Moreover, its flexibility allows for partial bending, making it suitable for use in foldable displays.

[0069] like Figure 2 and Figure 3 As shown, in some embodiments, the edge region of the glass layer or ceramic layer 1072 is provided with adhesive 1073, and the glass layer or ceramic layer 1072 is bonded to the inorganic water and oxygen barrier layer 1071 by adhesive 1073.

[0070] In this embodiment, adhesive 1073 is provided at the edge of the glass layer or ceramic layer 1072. This adhesive application not only ensures the adhesion of the inorganic water and oxygen barrier layer 1071, improving the stability of the display panel, but also allows for integrated cutting of the glass layer (or ceramic layer) and the adhesive coating, reducing breakage during cutting and improving the cutting effect. For example, the structure of the glass layer or ceramic layer 1072 before cutting is as follows: Figure 4 As shown, the width of the glass or ceramic layer 1072 is greater than the width of the inorganic water and oxygen barrier layer 1071. When applied to the display panel 100, it can be cut. Due to the adhesive applied to its edge areas, the glass (or ceramic) and the adhesive coating can be cut together during the cutting process. Figure 2 The glass or ceramic layer 1072 in the middle is the structure after cutting.

[0071] like Figure 5 As shown in the figure, this application embodiment also proposes a display module 200, including a cover plate 105 and a display panel 100 of the above embodiment, with a touch layer 101 located between the cover plate 105 and the light-emitting layer 102.

[0072] For a detailed description of the implementation of the display panel 100 in the display module 200, please refer to the above description of the display panel 100 embodiment, which can achieve the same beneficial effects. To avoid repetition, it will not be described in detail here.

[0073] like Figure 5 As shown, in some embodiments, the display module 200 further includes:

[0074] The support layer 108 and the base layer 107 of the display panel are located between the semiconductor circuit layer 106 and the support layer 108 of the display panel 100.

[0075] In this embodiment, the display module 200 includes the aforementioned display panel 100 and a support layer 108 (SuperClean Foam, SFC). The support layer 108 can be used to support the display panel 100, providing support and resisting external forces, thus providing impact protection for the display module 200.

[0076] like Figure 6 and Figure 7 As shown, in some embodiments, the support layer 108 includes:

[0077] The support mesh 1081 has a first non-Newtonian fluid adhesive layer 1083 coated on its first side and a second non-Newtonian fluid adhesive layer 1084 coated on its second side. The first side faces the display panel and the second side faces away from the display panel.

[0078] The frame 1082 connects to the edge of the support mesh 1081 and is connected to the frame of the electronic device.

[0079] Non-Newtonian fluid adhesive is an adhesive with non-Newtonian rheological properties. Due to its unique flow characteristics, the non-Newtonian fluid adhesive layer can provide good cushioning effect when subjected to impact. Both sides of the support mesh 1081 are coated with a non-Newtonian fluid adhesive layer. In addition, the edge of the support mesh 1081 is connected to the frame 1082, and the support mesh 1081 is fixed to the frame 1082 (as an example, the support mesh 1081 can be fixed to the frame 1082 bracket). The support mesh 1081 is taut under the action of the frame 1082, generating a certain tension. The non-Newtonian fluid adhesive layer and the support mesh 1081 are stretched synchronously, which can maintain preload and elasticity. The non-Newtonian fluid adhesive layer has instantaneous impact resistance and elasticity, thereby improving the impact resistance of the display module 200. As an example, the display module 200 is provided with a support layer 108 having this structure, and the frame 1082 is connected to the cover plate of the display module. The frame 1082 can be connected to the frame of the electronic device, which can provide a certain degree of protection for the display module 200 when subjected to external forces or impacts from external objects, thereby reducing color spots, top marks, and black spots. As an example, the support mesh 1081 is an elastic support mesh 1081.

[0080] In this embodiment, the support layer 108 is improved to include a frame 1082 and a support mesh 1081 coated with non-Newtonian fluid gel layers on both sides. The non-Newtonian fluid gel layers on both sides can achieve impact resistance and energy absorption. They interact with the support mesh 1081 through coating and are then stretched and fixed to the frame 1082 bracket to achieve a pre-tightening effect. The pre-tightening force can offset part of the external impact force when subjected to external impact, thereby improving the impact resistance level. The frame 1082 can be bonded and assembled with the cover plate 105 of the display module 200 and the frame (also called the middle frame) of the electronic device. The frame 1082 can be a plastic structure formed by injection molding or other methods, or it can be a sheet metal structure, which plays a fixing role.

[0081] In some embodiments, the support net 1081 is a mesh layer, and there are multiple support nets 1081 stacked together, with adjacent support nets 1081 having different mesh weaving directions.

[0082] As an example, the mesh layer can be made of plastic fiber materials such as carbon fiber or nylon, or other polymer elastic materials. In this embodiment, the number of support meshes 1081 is multiple, which can increase the thickness of the support meshes 1081 and improve impact resistance. Figure 8As shown in the example, there are three support nets 1081: a first support net 10811, a second support net 10812, and a third support net 10813. These three support nets are stacked, with the second support net 10812 located between the first and third support nets 10811 and 10813. The first support net 10811 is located between the base layer 107 and the second support net 10812. The support net 1081 is a mesh layer, including the mesh and the frame 1082, forming a support layer 108. It can also be called a non-cowhide mesh composite structure frame. The mesh layers are formed using a weaving process, and each mesh layer has its corresponding weaving direction, such as... Figure 8 As shown, the weaving directions of different mesh layers in multiple mesh layers can be the same or different, the weaving directions of adjacent mesh layers are different, and the weaving directions of the mesh layers are interlaced, forming an angle of 0 to 180 degrees, thereby improving the impact resistance of the display module in different directions. As an example, the mesh layer is an elastic mesh layer.

[0083] The display panel 100 provided in this application embodiment uses the aforementioned self-healing layer 1032 in the encapsulation layer 103, and a dam structure 104 with self-healing function can be provided in the encapsulation layer 103 to improve the impact resistance of the encapsulation layer 103, thereby improving the impact resistance of the display panel 100, and also having crack repair capabilities and inhibiting crack propagation, thus extending the service life of the display panel 100. In addition, the base layer 107 of the display panel 100 is improved to a rigid glass or ceramic material, which reduces the thickness of the display panel 100 while improving its impact deformation resistance. Moreover, the support layer 108 is improved to a non-woven mesh composite structure frame for support, further improving impact resistance. Through the improvements in materials and structure of the display panel 100 and support layer 108 in the display module 200 by this application embodiment, the impact resistance of the display panel 100 and the protective capability of the support layer 108 for the display panel 100 are improved.
