[0027] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in some embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments provided by the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present application.

[0028] Unless the context requires otherwise, throughout the specification and claims, the term "comprising" is to be construed in an open, inclusive sense, ie, meaning "including, but not limited to."

[0029] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

[0030] When describing some embodiments, the term "connection" and its derivative expressions may be used. The term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For example, when describing some embodiments, the term "connection" may be used to indicate that two or more components are in direct physical or electrical contact with each other.

[0031] Additionally, the use of “based on” is meant to be open and inclusive, as a process, step, calculation, or other action “based on” one or more stated conditions or values ​​may, in practice, be based on additional conditions or values ​​beyond those stated.

[0032] It will be understood that when a layer or an element is referred to as being on another layer or substrate, it can be directly on the other layer or substrate, or intervening layers may be present between the layer or element and the other layer or substrate.

[0033] Exemplary embodiments are described herein with reference to cross-sectional views that are idealized exemplary drawings. In the drawings, the thickness of layers and the area of ​​regions are exaggerated for clarity. Therefore, variations in shape relative to the drawings due to, for example, manufacturing techniques and / or tolerances are contemplated. Therefore, the exemplary embodiments should not be construed as limited to the shapes of the regions shown herein, but include deviations in shape due to, for example, manufacturing. For example, an etched region shown as a rectangle will typically have curved features. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to illustrate the actual shape of regions of the device, and are not intended to limit the scope of the exemplary embodiments.

[0034] Figure 1 It is a structural schematic diagram of a display module in the related art.

[0035] like Figure 1 As shown, the display module 1' includes a display panel 10'. In order to achieve a full-screen effect, a bending area 12' is usually set on one side of the display area 11' of the display panel 10'. For example, a bending area 12' is set on the side of the display area 11' close to the lower frame, so that the display panel 10' can be bent on the plane XZ, and the binding area (the binding area is provided with a Pad) used to connect the circuit is bent to the back of the display panel 10'.

[0036] Since the bending area 12 ′ is close to the edge of the display module 1 ′, it is easy to be bumped or squeezed, resulting in poor display. Usually, a modified chloroprene latex (MCL) adhesive is coated on the surface of the bending area 12 ′ to protect the bending area.

[0037] However, currently, MCL glue is usually designed and used with a thickness of 90μm. Thicker MCL glue is not conducive to further narrowing the screen frame. In addition, due to the process characteristics of MCL glue coating, reducing the coating thickness of MCL glue is prone to cause reliability problems such as glue breaking.

[0038] Based on this, an embodiment of the present application provides a display panel, such as Figure 2 As shown, Figure 2 A schematic diagram of the structure of a display panel provided in an embodiment of the present application; Figure 3 for Figure 2 A partial enlarged view of the display panel at position A; Figure 4 for Figure 2 A partial enlarged view of the display panel at point B.

[0039] like Figure 2 As shown, the display panel 10 includes a display area 11 and a bending area 12 arranged on one side of the display area 11. The display panel 10 includes a display substrate 13, the display substrate 13 includes a substrate 131, a pixel driving circuit 132 and a light emitting layer 133, wherein the pixel driving circuit 132 includes a plurality of thin film transistors, and the light emitting layer 133 includes a plurality of light emitting devices.

[0040] The display substrate 13 further includes a source-drain conductive layer 134, a first retaining wall 135 and a second retaining wall 136 located on the source-drain conductive layer 134, and a stacked layer 137. In addition, the display panel 10 further includes an encapsulation layer 14 disposed on the display substrate 13. When the encapsulation layer 14 includes an organic encapsulation layer, the organic encapsulation layer is formed by an inkjet printing process, and the first retaining wall 135 and the second retaining wall 136 can be used to prevent the organic encapsulation material from overflowing.

[0041] The stack 137 is a plurality of dielectric layers disposed in the bending zone 12 , and the stack 137 forms a groove in the bending zone 12 , the depth direction of the groove is direction Z, and the length direction is direction Y, so that the display panel 10 is bent at the groove in the bending zone 12 .

[0042] like Figure 2 As shown, the display panel 10 further includes at least one organic material layer 15 , which is disposed on a side of the encapsulation layer 14 away from the display substrate 13 , and extends from the display area 11 to the bending area 12 .

[0043] In the embodiment of the present application, at least one organic material layer 15 of the display area 11 is extended to the bending area 12, that is, the organic material layer 15 is used to cover the bending area 12 to replace the MCL glue to protect the bending area 12, thereby avoiding the aforementioned problems caused by the use of MCL glue.

[0044] Furthermore, the organic material layer 15 is made of organic material. According to the material properties of the organic material, the neutral layer can be adjusted to reduce the strain of the organic material layer 15 , improve the stress concentration problem of the display panel 10 during the bending process, and improve the bending performance of the display panel 10 .

[0045] In addition, the at least one organic material layer 15 extends from the display area 11 to the bending area 12, which means that the organic material layer 15 can be formed in the bending area 12 simultaneously during the process of forming the organic material layer 15 in the display area 11, without adding additional processes.

[0046] In some embodiments, Figure 2 As shown, the material of the organic material layer 15 includes at least one of acrylic resin, methacrylic resin, polyisoprene, vinyl resin, epoxy resin, polyurethane resin, cellulose resin, and siloxane. The above materials have the relevant characteristics of organic materials. While extending to the bending area 12 to protect the bending area 12, they can adjust the neutral layer, reduce strain, improve the problem of stress concentration during the bending process, and ensure the bending effect. In addition, the above materials have good insulation properties and can play a relevant role, such as electrical isolation, when used as relevant film layers in the display area 11. In addition, the preparation process is simpler when the above materials are used to form relevant film layers, and a uniform film thickness can be obtained by accurately controlling the coating and curing process.

[0047] In some embodiments, Figure 2 As shown, the display panel 10 further includes a touch structure 16 and a color filter 17. Figure 3 As shown, the touch control structure 16 includes a first conductive layer 161, a first insulating layer 162, a second conductive layer 163 and a second insulating layer 164 which are sequentially stacked on the packaging layer 14. Figure 4 As shown, the color filter 17 includes a color resist layer 171 and a third insulating layer 172 which are sequentially stacked on the second insulating layer 164 .

[0048] Among them, at least one of the first insulating layer 162, the second insulating layer 164 and the third insulating layer 172 is the above-mentioned organic material layer 15, that is, at least one of the first insulating layer 162, the second insulating layer 164 and the third insulating layer 172 is made of organic material, and the insulating layer made of organic material extends from the display area 11 to the bending area 12 to replace the MCL glue to protect the bending area 12.

[0049] For example, Figure 2 As shown, one of the first insulating layer 162 and the second insulating layer 164 of the touch structure 16 is made of an organic material, and the insulating layer made of the organic material extends from the display area 11 to the bending area 12 to replace the MCL glue to protect the bending area 12. Alternatively, the first insulating layer 162 and the second insulating layer 164 are both organic material layers 15, and both extend from the display area 11 to the bending area 12 to protect the bending area 12.

[0050] In the related art, the first insulating layer and the second insulating layer in the touch structure are usually made of inorganic materials, such as silicon oxide, silicon nitride, silicon oxynitride, aluminum oxide, titanium dioxide, tantalum oxide, hafnium oxide, or zinc oxide, etc. In the above embodiment of the present application, at least one of the first insulating layer 162 and the second insulating layer 164 is replaced by an organic material instead of an inorganic material, and the insulating layer made of the organic material is extended from the display area 11 to the bending area 12 to replace the MCL glue to protect the bending area 12.

[0051] Furthermore, during the process of forming the touch structure 16 , at least one of the first insulating layer 162 and the second insulating layer 164 is simultaneously formed in the bending region 12 , without adding additional processes.

[0052] Figure 5 A schematic diagram of the structure of another display panel provided in an embodiment of the present application.

[0053] like Figure 5 As shown, the third insulating layer 172 of the color filter 17 is the above-mentioned organic material layer 15, and the third insulating layer 172 extends from the display area 11 to the bending area 12 to protect the bending area 12. In addition, in the process of forming the color filter 17, the third insulating layer 172 is simultaneously formed in the bending area 12, and no additional process is added.

[0054] Figure 6 A schematic diagram of the structure of another display panel provided in an embodiment of the present application.

[0055] like Figure 6 As shown, in the touch structure 16, at least one of the first insulating layer 162 and the second insulating layer 164 is made of organic material, and the third insulating layer 172 of the color filter 17 is also made of organic material. The insulating layer made of organic material extends from the display area 11 to the bending area 12 to replace the MCL glue to protect the bending area 12.

[0056] Exemplarily, the first insulating layer 162 and the third insulating layer 172 are both organic material layers 15, and both extend from the display area 11 to the bending area 12 to protect the bending area 12. Alternatively, the second insulating layer 164 and the third insulating layer 172 are both organic material layers 15, and both extend from the display area 11 to the bending area 12 to protect the bending area 12. Alternatively, the first insulating layer 162, the second insulating layer 164 and the third insulating layer 172 are all organic material layers 15, and all three extend from the display area 11 to the bending area 12 to protect the bending area 12.

[0057] In some embodiments, at least one organic material layer 15 is disposed in the bending region 12 of the display panel 10, and the total thickness of the one or more organic material layers 15 located in the bending region 12 is less than 90 μm. For example, the total thickness of the organic material layer 15 may be 10 μm, 30 μm, 45 μm, 70 μm or 80 μm.

[0058] It is understandable that the coating process of MCL glue makes the thickness of MCL glue relatively large. The thickness of MCL glue can reach 90μm. In the present application, the organic material layer 15 is formed by a thin film deposition process, which can form a thinner and continuous organic material layer 15, so that the total thickness of one or more organic material layers 15 in the bending area 12 is less than 90μm, which is conducive to achieving a narrow frame of the screen.

[0059] In some examples, the organic material layer 15 is formed by a thin film deposition process, and the thickness of each organic material layer 15 is in the range of 1.5 μm to 3 μm, so that the total thickness of one or more organic material layers 15 in the bending area 12 can be less than 10 μm. For example, the total thickness of the organic material layer 15 can be 1 μm, 3 μm, 5 μm, 7 μm or 9 μm, which can further reduce the width of the screen border.

[0060] In other examples, the total thickness of one or more organic material layers 15 located in the bending zone 12 may also be greater than or equal to 10 μm, but still less than 90 μm, so as to protect the bending zone 12 and achieve a narrow frame while ensuring that the total thickness of the organic material layer 15 in the bending zone 12 meets the requirements for adjusting the neutral layer.

[0061] In some embodiments, Figure 6As shown, the second insulating layer 164 of the touch structure 16 and the third insulating layer 172 of the color filter 17 are both organic material layers 15, and both the second insulating layer 164 and the third insulating layer 172 extend from the display area 11 to the bending area 12. The thickness of the second insulating layer 164 ranges from 1.5 μm to 3 μm, for example, the thickness of the second insulating layer 164 is 1.5 μm, 2 μm, 2.25 μm, 2.5 μm or 3 μm. The thickness of the third insulating layer 172 ranges from 1.5 μm to 3 μm, for example, the thickness of the third insulating layer 172 is 1.5 μm, 2 μm, 2.25 μm, 2.5 μm or 3 μm.

[0062] The total thickness of the second insulating layer 164 and the third insulating layer 172 in the bending area 12 is in the range of 3μm to 6μm, which is less than 10μm. Compared with the related art, the thickness of the protective layer in the bending area 12 is reduced from 90μm of MCL glue to 3μm to 6μm, which greatly reduces the thickness of the protective layer and is conducive to achieving an extremely narrow frame of the screen.

[0063] The embodiment of the present application further provides a display module, Figure 7 A schematic diagram of the structure of a display module provided in an embodiment of the present application.

[0064] like Figure 7 As shown, in the display module 1, the glass cover CG covers the display area 11 and the bending area 12 of the display panel 10, and generally the distance c from the outermost side of the bending to the edge of the glass cover CG is kept at a fixed value to prevent the bending area 12 from being bumped. Figure 1 As shown, the thickness of the MCL glue is d, and the distance from the edge of the display area 11' to the outermost side of the bend is b. In the embodiment of the present application, the sum of the thicknesses of the organic material layer 15 extending from the display area 11 to the bending area 12 is e, then in the embodiment of the present application, the distance from the edge of the display area 11 to the outermost side of the bend is reduced to b'=b-(de). According to the aforementioned related embodiments, it can be seen that usually d=90μm, and e<10μm, or in some embodiments, 10μm≤e<90μm. That is, in the embodiment of the present application, the organic material layer 15 extending from the display area 11 to the bending area 12 is used to replace the MCL glue in the related art, which greatly reduces the thickness of the protective layer, and then reduces the thickness of the bending area 12, which is beneficial to reduce the frame width and provides favorable conditions for a smaller bending radius.

[0065] In some embodiments, Figure 7 As shown, in the display module 1, the display panel 10 includes a first portion 101 (eg, Figure 7The display panel 10 is shown in FIG. 1 , and the second portion 102 and the third portion 103 are located on opposite sides of the bending area 12, and the second portion 102 is located on the display area 11. The first portion 101 of the display panel 10 is bent, and the third portion 103 is located on the back of the second portion 102. The second portion 102, the first portion 101 and the third portion 103 form a cavity K1. The display panel 10 also includes a first filling layer 104, which is disposed in the cavity K1 and contacts a side of the first portion 101 close to the cavity K1.

[0066] In the embodiment of the present application, since the MCL glue is no longer applied, the thickness of the protective layer of the bending area 12 becomes thinner and the protection strength is correspondingly affected to a certain extent. In order to improve the protection strength of the bending area 12 (or the first portion 101), the following can be done: Figure 7 As shown, a first filling layer 104 is provided in the cavity K1. That is, before the first part 101 is bent, glue is dispensed on the inner side of the bend, and as the bend is formed, the glue is filled in the cavity K1 formed by the bend to form the first filling layer 104. The "glue" here can be at least one of acrylic resin, methacrylic resin, polyisoprene, vinyl resin, epoxy resin, polyurethane resin, cellulose resin, and siloxane. When impacted or squeezed, the cured glue, i.e., the first filling layer 104, can play a supporting and buffering role, and can ensure that the first part 101 will not bend dead.

[0067] In some embodiments, Figure 7 As shown, the display panel 10 further includes a second filling layer 105 . The second filling layer 105 is disposed in the bending area 12 and contacts a side of the first portion 101 away from the cavity K1 .

[0068] like Figure 7As shown, first, on the outside of the bending area 12, a first blocking dam 107 is formed on the surface of the binding area bent to the back of the display panel 10 by printing with high-viscosity glue, and a second blocking dam 108 is formed on the surface of the glass cover plate CG. The "high-viscosity glue" here can be at least one of acrylic resin, methacrylic resin, polyisoprene, vinyl resin, epoxy resin, polyurethane resin, cellulose resin, and siloxane. Then, the filling glue 109 is injected between the first blocking dam 107 and the second blocking dam 108 by dispensing, and the cured filling glue 109 and the first bank 107 and the second bank 108 form the above-mentioned second filling layer 105 together. Among them, the filling glue 109 can be at least one of acrylic resin, methacrylic resin, polyisoprene, vinyl resin, epoxy resin, polyurethane resin, cellulose resin, and siloxane. The filling glue 109 has good fluidity, which can make the final second filling layer 105 have a relatively flat surface, which is convenient for the subsequent installation of the whole machine middle frame. The second filling layer 105 supports and protects the bending area 12 to prevent the first portion 101 from being hit or squeezed and thus being bent.

[0069] In some embodiments, Figure 7 As shown, the display module 20 further includes a plurality of films 21 , wherein the display panel 10 includes a light-emitting side and a non-light-emitting side opposite to each other, and the plurality of films 21 are disposed on the non-light-emitting side of the display panel 10 .

[0070] Exemplarily, a first back film (U-film) 201 is further provided on the inner side of the bend, that is, the side of the second part 102 close to the third part 103 after the bend, and a second back film 202 is further provided on the side of the third part 103 close to the second part 102. A heat dissipation film (Super Clean Foam, SCF) 204 and a spacer (spacer) 203 are further provided between the first back film 201 and the second back film 202, wherein the spacer 203 is usually a glue layer for providing good optical performance and bonding strength. In addition, an optically clear adhesive (OCA) 22 is further provided on the light-emitting side of the second part 102, and the material of the optical adhesive layer 22 includes optically transparent adhesive, which can be used as an adhesive, and the optically transparent adhesive has good light transmittance and will not affect the screen display effect.

[0071] The above multiple films 21 are used to provide a certain bending radius for the display panel 10 to avoid the first part 101 from being bent due to a too small bending radius. As the thickness of the protective layer of the bending area 12 decreases, the thickness of the bending area 12 is further reduced, providing favorable conditions for a smaller bending radius. Therefore, the thickness of the multiple films 21 can also be adaptively reduced, thereby achieving a thinner display module 20.

[0072] The present application also provides a display device, such as Figure 8 As shown, Figure 8 A schematic diagram of the structure of a display device provided in an embodiment of the present application. The display device 2 includes the display module 1 and the circuit board 3 mentioned above, wherein the circuit board 3 is arranged on the side of the multiple membranes 21 of the display module 1 away from the display panel 10. The circuit board 3 is arranged on the non-display side of the display module 1 to provide a driving signal for the display module 1 so that the display module 1 displays an image. In addition, the display device 2 also includes a whole machine middle frame 4, which is used to support and fix the internal component structures to prevent the display module 1 from being damaged by external impact. The material of the whole machine middle frame 4 generally includes at least one of metal (such as aluminum alloy, titanium alloy) or non-metal (such as plastic, glass).

[0073] The display device 2 described above may be any device that displays images, whether in motion (e.g., video) or fixed (e.g., still images), and whether textual or . More specifically, it is contemplated that the embodiments described may be implemented in or associated with a variety of electronic devices, such as (but not limited to) mobile phones, wireless devices, personal data assistants (PDAs), handheld or portable computers, GPS receivers / navigators, cameras, MP4 video players, camcorders, game consoles, watches, clocks, calculators, television monitors, flat panel displays, computer monitors, automotive displays (e.g., odometer displays, etc.), navigators, cockpit controls and / or displays, displays of camera views (e.g., displays of rear-view cameras in vehicles), electronic photographs, electronic billboards or signs, projectors, architectural structures, packaging, and aesthetic structures (e.g., displays of images of a piece of jewelry), etc.

[0074] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that a person skilled in the art can think of within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
