DETAILED DESCRIPTION

[0050] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0051] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0052] Currently, there is fierce competition in the mobile phone market. As an important component, the screen has higher and higher requirements on its reliability and price.

[0053] In the related art, refer to Figures 1 to 3 The display panel 100 includes a first protective layer 110, a second protective layer 120 and a screen body located between the first protective layer 110 and the second protective layer 120, the screen body includes a display area 103, an area to be opened 101 and a transition area 102, the transition area 102 is located between the display area 103 and the area to be opened 101, the screen body (also referred to as a display substrate) includes a stacked array substrate 130, a display function layer 170, an encapsulation layer 140, a filling layer 160 and a touch layer 150, wherein the filling layer 160 includes a resin liquid and is manufactured by a spraying resin liquid anti-shattering (OC0) process. The strength of the screen body can be increased by spraying the resin liquid. In the area to be opened 101, the thickness of the screen body with the filling layer 160 is consistent with that of the screen body in other areas, so that there is no gap between the second protective layer 120 and the screen body.

[0054] Reference Figure 3Due to the cost reduction demand of the screen body, the OC0 process needs to be cancelled, that is, the filling layer 160 is no longer arranged between the encapsulation layer 140 and the array substrate 130. The inventors found that the following problems exist in the related art: after the filling layer 160 is cancelled, the thickness of the screen body in the area 101 to be opened is smaller than that in other areas. After the second protective layer 120 is attached to the screen body, a second gap 12 is generated between the second protective layer 120 and the screen body in the area 101 to be opened. Before opening the hole, the first protective layer 110 needs to be torn off. In this process, the second protective layer 120 and the screen body can be adsorbed and fixed together. Since the thickness of the screen body in the area 101 to be opened is relatively small, after the screen body is subjected to the tension from the side where the first protective layer 110 is located, the stress is concentrated in the area 101 to be opened, and deformation is likely to occur, resulting in the failure problems such as peeling and black spots on the film layer of the screen body.

[0055] Figure 1 The diagram is a schematic diagram of the peeling problem around the area to be opened 101 when the first protective layer 110 is torn off. The arrow direction in the figure is the tearing direction.

[0056] Based on this, the present application provides a display panel solution, which adjusts the design structure of the display panel in the area to be opened to solve the above technical problems. See the following embodiments for details.

[0057] Reference Figure 4 , a display panel 100 provided in an embodiment of the present application, the area to be opened 101, the display panel 100 comprises a display substrate and a first protective layer 110 and a second protective layer 120 located on both sides of the display substrate, the display substrate comprises an array substrate 130 and an encapsulation layer 140, wherein the encapsulation layer 140 is located on one side of the array substrate 130, the display substrate comprises a display area 103, an area to be opened 101 and a transition area 102, wherein the transition area 102 is located between the display area 103 and the area to be opened 101. The first protective layer 110 is located on a side of the array substrate 130 away from the encapsulation layer 140, and the second protective layer 120 is located on a side of the encapsulation layer 140 away from the array substrate 130; in the area to be opened 101, a first gap 11 is provided between the first protective layer 110 and the array substrate 130. wherein the orthographic projection of the first gap 11 on the array substrate 130 may overlap with the area to be opened 101.

[0058] Reference Figure 5 In another embodiment, the orthographic projection of the first gap 11 on the array substrate 130 is located in the area to be opened 101 .

[0059] Reference Figure 8 In another embodiment, the orthographic projection of the first protection layer 110 on the array substrate 130 does not overlap with the area to be opened 101 .

[0060] Reference Fig. 9In another embodiment, the orthographic projection of the first protective layer 110 on the array substrate 130 overlaps with part of the area to be opened 101. That is, the coverage of the first protective layer 110 at most partially overlaps with the area to be opened 101, and the first protective layer 110 does not completely cover the area to be opened 101.

[0061] Specifically, the area to be drilled 101 may be, for example, a drilling area for components such as cameras and sensors where drilling operations are required. The first protective layer 110 and the second protective layer 120 correspond to the lower protective film and the upper protective film, respectively. Before the drilling operation, the lower protective film corresponding to the first protective layer 110 needs to be torn off. The display panel 100 provided in the present application sets a first gap 11 between the first protective layer 110 in the area to be opened 101 and the array substrate 130, or the first protective layer 110 does not cover or partially covers the area to be opened 101. During the process of tearing off or sticking the first protective layer 110, the tension or pressure on the side where the first protective layer 110 is located on the array substrate 130 or the entire display substrate in the area to be opened 101 will be greatly reduced, or even not subjected to stress, thereby reducing stress concentration, thereby eliminating deformation of the hole area, avoiding undesirable conditions such as breakage and peeling of the film layer due to deformation of the display panel 100 in the area to be opened 101, and preventing water and oxygen from invading the display area 103 and generating black spots in the display area 103.

[0062] Reference Figure 6 In one embodiment, the first protective layer 110 includes a first body layer 111 and a first adhesive layer 112, and the orthographic projection of the first adhesive layer 112 on the array substrate 130 does not overlap with the area to be opened 101, thereby forming a first gap 11 between the first body layer 111 and the array substrate 130.

[0063] Among them, the orthographic projection of the first adhesive layer 112 on the array substrate 130 has no overlap with the area to be opened 101, that is, the first adhesive layer 112 is not provided on the first main layer 111 in the area to be opened 101. Therefore, when the first protective layer 110 is torn off or pasted, the array substrate 130 or the entire display substrate located in the area to be opened 101 will not be subjected to tension or pressure from the side where the first protective layer 110 is located, thereby reducing stress concentration and preventing the display panel 100 from deforming in the area to be opened 101 and causing the film layer to break.

[0064] Optionally, refer to Figure 5 In the plane where the display panel 100 is located, the area where the first gap 11 is located covers a portion of the area 101 to be opened.

[0065] Reference Figure 7In one embodiment, the first protective layer 110 includes a first body layer 111 and a first adhesive layer 112, and the orthographic projection of the first adhesive layer 112 on the array substrate 130 overlaps with a portion of the area to be opened 101, thereby forming a first gap 11 between the first body layer 111 and the array substrate 130.

[0066] Among them, the orthographic projection of the first adhesive layer 112 on the array substrate 130 overlaps with a part of the area to be opened 101, that is, the area of ​​the first adhesive layer 112 in the area to be opened 101 is smaller than the first main layer 111. Therefore, when the first protective layer 110 is torn off or pasted, the tension or pressure on the side where the first protective layer 110 is located on the array substrate 130 or the entire display substrate located in the area to be opened 101 will be greatly reduced, thereby reducing stress concentration and avoiding deformation of the display panel 100 in the area to be opened 101 and causing the film layer to break.

[0067] Reference Figure 4 In one embodiment, in the area to be opened 101, a second gap 12 is provided between the second protection layer 120 and the encapsulation layer 140. The second gap 12 is generated because the existing filling layer 160 is eliminated to save costs; specifically, a portion of the encapsulation layer 140 sinks toward the original position of the filling layer 160, so that the second gap 12 is formed on the side of the encapsulation layer 140 away from the array substrate 130.

[0068] Reference Fig.10 In one embodiment, the display panel 100 further includes a touch layer 150, the touch layer 150 is located between the second protection layer 120 and the encapsulation layer 140, and the second gap 12 is located between the second protection layer 120 and the touch layer 150. The touch layer 150 receives the user's touch action and responds to it, thereby realizing touch control of the display panel 100.

[0069] Continue to refer to Fig.10 In one embodiment, the touch layer 150 includes a first touch layer 151 and a second touch layer 152, the second touch layer 152 is located on a side of the first touch layer 151 away from the array substrate 130, and the second gap 12 is located between the second protection layer 120 and the second touch layer 152. The first touch layer 151 is closer to the array substrate 130 than the second touch layer 152, and the second touch layer 152 protects the first touch layer 151, thereby ensuring good touch performance of the display panel 100. Exemplarily, touch electrodes or touch traces are provided in both the first touch layer 151 and the second touch layer 152.

[0070] Reference Fig.11In one embodiment, the second protective layer 120 includes a second body layer 121 and a second adhesive layer 122 . The second adhesive layer 122 includes a protrusion 123 . The protrusion 123 extends into the second gap 12 and fills the second gap 12 .

[0071] Reference Fig.12 In another embodiment, the protruding portion of the second adhesive layer 122 extends into the second gap 12 and fills a portion of the second gap 12 .

[0072] Among them, the second gap 12 is filled by designing a convexity on the second adhesive layer 122 of the second protective layer 120, so that the part of the display substrate located in the area to be opened 101 is adhered and fixed. When the first protective layer 110 is torn off or pasted, the difference between the force on the display substrate in the area to be opened 101 and the force on other areas is reduced, which improves the stress concentration phenomenon and avoids the large deformation of the display substrate in the area to be opened, which may cause film breakage, black spots and other undesirable problems.

[0073] In one embodiment, the second protective layer 120 includes a second protective film, and the first protective layer 110 includes a first protective film. The first protective film and the second protective film protect opposite sides of the display substrate, thereby improving the packaging performance and display reliability of the display panel 100.

[0074] Alternatively, in one embodiment, the second protective layer 120 includes a second protective film, and the first protective layer 110 includes a supporting film. The supporting film provides structural support and reinforcement for the display panel 100 to prevent the display panel 100 from curling during manufacturing and use. In particular, for a flexible OLED screen, the supporting film can effectively maintain the shape of the screen and prevent undesirable deformation during bending.

[0075] Reference Fig.13 In one embodiment, the encapsulation layer 140 includes an inorganic encapsulation layer and an organic encapsulation layer 143, and the inorganic encapsulation layer is located on the side of the organic encapsulation layer 143 away from the array substrate 130. Further, the inorganic encapsulation layer includes a first inorganic encapsulation layer 141 and a second inorganic encapsulation layer 142, and the second inorganic encapsulation layer 142 is located on the side of the first inorganic encapsulation layer 141 away from the array substrate 130. Among them, the encapsulation layer 140 adopts a multilayer structure including an organic encapsulation layer and an inorganic encapsulation layer. On the one hand, the organic encapsulation layer usually has good flexibility and conformability, and can adapt to the complex shape and curved surface design of the display panel; the inorganic encapsulation layer has high hardness and wear resistance, and can effectively protect the display panel from damage from the external environment, such as scratches, impacts and moisture erosion; on the other hand, the combination of the organic encapsulation layer and the inorganic encapsulation layer can improve stress matching, which helps to improve the bending characteristics of the display panel, so that the panel can maintain good stability and durability when subjected to external pressure or deformation.

[0076] Continue to refer to Fig.13 In one embodiment, the display panel 100 further includes a dam 180, which is located in the transition area 102 and is arranged around the area to be opened 101; the dam 180 is located between the array substrate 130 and the inorganic encapsulation layer, and the dam 180 is located on a side of the organic encapsulation layer 143 close to the area to be opened 101. The organic encapsulation layer 143 is blocked by the dam 180 to prevent the organic encapsulation layer 143 from overflowing to the area to be opened 101. Exemplarily, the dam 180 is an insulating structure, which can be made of an organic insulating material, such as polyimide or acrylic.

[0077] Reference Fig.13 In one embodiment, the array substrate 130 includes a stacked substrate layer 131 and a barrier layer 132, wherein the barrier layer 132 is located between the substrate layer 131 and the display function layer 170, wherein the array substrate 130 provides support for other film layers of the display panel, such as the display function layer 170 and the encapsulation layer 140. Exemplarily, the substrate layer 131 may be a rigid substrate, such as a stainless steel plate. The substrate layer 131 may also be a flexible substrate, such as polyimide, polyethylene terephthalate, or polycarbonate. The material of the barrier layer 132 may be an inorganic insulating material such as silicon nitride or silicon oxide.

[0078] Reference Fig.14 As shown, another embodiment of the present application further provides a display panel 100. The display panel 100 includes a display substrate and a first protective layer 110 and a second protective layer 120 located on both sides of the display substrate. The display substrate includes an array substrate 130 and an encapsulation layer 140, wherein the encapsulation layer 140 is located on one side of the array substrate 130. The display substrate includes a display area 103, an area to be opened 101, and a transition area 102, wherein the transition area 102 is located between the display area 103 and the area to be opened 101. The first protective layer 110 is located on a side of the array substrate 130 away from the encapsulation layer 140, and the second protective layer 120 is located on a side of the encapsulation layer 140 away from the array substrate 130. A protrusion 123 is provided on a side of the second protective layer 120 close to the encapsulation layer 140.

[0079] The area to be drilled 101 is located within the orthographic projection area of ​​the protrusion 123 on the array substrate 130. Alternatively, the orthographic projection of the protrusion 123 on the array substrate 130 overlaps with a portion of the area to be drilled 101.

[0080] In the display panel 100 of the present embodiment, the raised portion 123 of the second protective layer 120 is at least partially located in the area to be opened 101, thereby protecting the portion of the display substrate located in the area to be opened 101. When the first protective layer 110 is torn off or applied, the difference between the force on the display substrate in the area to be opened 101 and the force on other areas is reduced, thereby improving the stress concentration phenomenon and avoiding large deformation of the display substrate in the area to be opened, thereby preventing film breakage, black spots and other undesirable problems.

[0081] It should be noted that Figure 1 The area to be opened 101 is shown as a circle, which is only a schematic diagram. In fact, the shape of the area to be opened 101 can be square, oval, teardrop-shaped, etc., and the shape of the area to be opened 101 is not specifically limited here. The transition area 102 is at least partially arranged around the area to be opened 101. In addition, the area to be opened 101 in the present application is in a pre-opening state, and a through hole is subsequently formed in the area corresponding to the area to be opened 101.

[0082] Reference Fig.15 As shown, another embodiment of the present application further provides a display panel 100. The display panel 100 includes a display substrate and a first protective layer 110 and a second protective layer 120 located on both sides of the display substrate. The display substrate includes an array substrate 130 and an encapsulation layer 140, wherein the encapsulation layer 140 is located on one side of the array substrate 130. The display substrate includes a display area 103, an area to be opened 101, and a transition area 102, wherein the transition area 102 is located between the display area 103 and the area to be opened 101. The first protective layer 110 is located on a side of the array substrate 130 away from the encapsulation layer 140, and the second protective layer 120 is located on a side of the encapsulation layer 140 away from the array substrate 130. A recessed portion 113 is provided on a side of the first protective layer 110 close to the array substrate 130, and the area to be opened 101 is located within the orthographic projection area of ​​the recessed portion 113 on the array substrate 130.

[0083] The display panel 100 of the present embodiment has a recessed portion 113 between the first protective layer 110 and the array substrate 130 in the area 101 to be opened. In the area 101 to be opened, the array substrate 130 or the entire display substrate will not be subjected to tension or pressure from the side where the first protective layer 110 is located, thereby avoiding stress concentration, avoiding film breakage due to deformation of the display panel 100 in the area 101 to be opened, and avoiding water and oxygen intrusion into the display area 103 to generate black spots in the display area 103, thereby improving product yield.

[0084] In some embodiments, the depth of the recessed portion 113 is less than the thickness of the first protective layer 110 .
