DETAILED DESCRIPTION

[0028] The following are preferred implementations of the present application. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of the cover of the present application.

[0029] Before introducing the technical solutions provided by this application, the technical problems in the related technologies are introduced in detail.

[0030] Flexible screens have the characteristics of low power consumption and bendability, and have been widely used in a variety of electronic devices. Taking foldable mobile phones as an example, the flexible screen in a foldable mobile phone generally includes a cover layer (Cover layer), a display layer (Panel layer), a support layer (Ufilm ​​layer), and a backplane layer (BKT layer) stacked in sequence, and each film layer is bonded by glue. In addition, each film layer may also have a mutually bonded structure. For example, the cover layer may be bonded by two or more layers of polyethylene terephthalate (PET), transparent polyimide (CPI), ultra-thin flexible glass (UTG), and ultra-thin flexible glass (UFG) of unequal thickness. However, in the process of preparing and using foldable screen mobile phones, the performance of the edge of the flexible screen will be reduced due to various reasons.

[0031] For example, when the film layers of the flexible screen are cut and produced, certain damage may occur to the edges of the film layers, thereby reducing the strength of the edges of the folding screen. For example, inorganic materials such as UTG or UFG may produce microcracks on the edges when they are cut, and organic materials such as PET or CPI may produce heat-affected zones when they are cut, resulting in carbonization of the edges. These damages may cause the edge strength of the flexible screen to be relatively poor during or after the installation of the flexible screen, causing the flexible screen to break when the edge of the flexible screen contacts the decorative parts (Deco), pressing blocks, and the middle frame. Or pressing the edge of the flexible screen during the use of a folding phone may also cause cracks in the flexible screen.

[0032] At the same time, after multiple foldings, the film layers of the flexible screen may be separated and delaminated due to the displacement between the film layers. This delamination not only occurs between the film layers, but also may occur within the film layers. For example, the double pi layer inside the panel layer may be delaminated, or the PET layer and UTG layer inside the cover layer may be delaminated.

[0033] In view of this, in order to solve the above problems, this application provides a display module. Please refer to Figure 1-Figure 3 , Figure 1 It is a cross-sectional schematic diagram of a display module in one embodiment of the present application. Figure 2 This is a schematic diagram of an adhesive layer disposed in a folding area in one embodiment of the present application. Figure 3 This is a schematic diagram of another embodiment of the present application in which an adhesive layer is disposed in a folding area.

[0034] The display module 1 provided in this embodiment includes a display component 10 and an adhesive layer 20. The display component 10 includes a display surface and a non-display surface arranged opposite to each other, and a side surface arranged between the display surface and the non-display surface. The display component 10 has a folding area 11. Along the folding direction of the display component 10, the adhesive layer 20 is bonded to the side surface of the display component 10 located in the folding area 11.

[0035] The display module 1 provided in this embodiment is mainly used as a flexible screen, installed in a folding screen mobile phone and used to display images. The folding screen mobile phone mentioned in this embodiment includes but is not limited to a horizontal folding mobile phone, a vertical folding mobile phone, a multi-folding mobile phone, etc.

[0036] The display module 1 mainly includes a display component 10 and an adhesive layer 20, wherein the display component 10 is mainly used to emit light to display images, and the adhesive layer 20 is mainly used to be arranged on part of the side or all of the side of the display component 10 to protect the display component 10. Optionally, the material of the adhesive layer 20 includes but is not limited to silicone gel, optical transparent glue, etc. The display component 10 includes a display surface and a non-display surface arranged opposite to each other. In other words, the display component 10 has two sides, one side can emit light and is the display surface, and the other side cannot emit light and is the non-display surface.

[0037] At the same time, the display component 10 also has a side surface arranged between the display surface and the non-display surface. In other words, the display surface and the non-display surface are arranged opposite to each other, the side surface is arranged between the display surface and the non-display surface, and the side surface connects the display surface and the non-display surface. The display component 10 has a folding area 11 and a non-folding area 12. In other words, when the display component 10 is applied to a folding screen mobile phone, and the folding screen mobile phone is folded and bent, the area where the display component 10 is bent is the folding area 11, and the area where the display component 10 is not bent is the non-folding area 12. Optionally, the display component 10 has two non-folding areas 12, one folding area 11, and two non-folding areas 12 are arranged on both sides of the folding area 11.

[0038] Along the folding direction of the display assembly 10 ( Figure 2 In other words, along the fold direction perpendicular to the display component 10, the adhesive layer 20 can be bonded to the side of the display component 10 in the folding area 11. Figure 2 As shown, the adhesive layer 20 is bonded to the side surface of the display assembly 10 within the dotted frame.

[0039] From the above content, it can be known that during the manufacturing and use of the flexible screen, the strength of the edge of the flexible screen is often reduced due to various reasons, which makes the edge of the flexible screen prone to breakage, delamination and other problems. In this embodiment, the adhesive layer 20 is bonded to the edge of the display component 10, that is, the side of the display component 10 in the folding area 11, so as to protect the display component 10, prevent the display component 10 from being impacted, and prevent further expansion of the damage to the edge of the display component 10 in the folding area 11. At the same time, the adhesive layer 20 bonded to the side of the display component 10 in the folding area 11 can also bond the multi-layer display component 10 more firmly, thereby preventing the display component 10 from being delaminated, and further improving the strength of the edge of the display component 10 in the folding area 11.

[0040] In summary, this embodiment improves the strength of the edge of the display component 10 in the folding area 11 by bonding the adhesive layer 20 to the side of the display component 10 in the folding area 11, thereby reducing the risk of damage to the edge of the display component 10 in the folding area 11 during use after the display component 10 is installed in the folding screen mobile phone.

[0041] Optionally, the installation process of the adhesive layer 20 includes but is not limited to inkjet printing, manual gluing, etc., so the process of installing the adhesive layer 20 can also be called glue dispensing.

[0042] Optionally, the adhesive layer 20 may include multiple sub-adhesive layers 21, and the multiple sub-adhesive layers 21 are arranged at intervals along the extension direction of the adhesive layer 20, so as to reduce the amount of glue used in the adhesive layer 20, thereby reducing the influence of the adhesive layer 20 on the folding effect of the display component 10.

[0043] Please refer to Figure 4 , Figure 4 2 is a cross-sectional schematic diagram of an embodiment of the present application in which an adhesive layer is disposed on the side of the display layer. In this embodiment, the display assembly 10 includes a display layer 13, and a cover layer 14 and a support layer 15 bonded to opposite sides of the display layer 13. The display layer 13 includes a first substrate layer 131 and a second substrate layer 132 stacked in layers. The adhesive layer 20 is bonded to the side of the display layer 13, thereby simultaneously connecting the side of the first substrate layer 131 and the side of the second substrate layer 132.

[0044] The display assembly 10 includes a display layer 13, a cover layer 14, and a support layer 15, wherein the display layer 13 (Panel layer) is mainly used to emit light to display images. The cover layer 14 (Cover layer) is arranged on the side of the display layer 13 that emits light to protect the display layer 13, and light can penetrate the cover layer 14. The support layer 15 (Cover-Panel layer and Ufilm ​​layer) is arranged on the other side of the display layer 13, and the support layer 15 has a certain rigidity, so that the flexible and bendable display layer 13 can remain flat and prevent wrinkles. The cover layer 14 and the support layer 15 are bonded to both sides of the display layer 13 by glue. In other words, the cover layer 14 is bonded to one side of the display layer 13 by the glue layer 18, and the support layer 15 is bonded to the other side of the display layer 13 by the glue layer 18. The display layer 13 further includes a first substrate layer 131 and a second substrate layer 132 which are stacked. In other words, the display layer 13 also has a stacked structure and includes at least two layers of the first substrate layer 131 and the second substrate layer 132. The first substrate layer 131 and the second substrate layer 132 are bonded by glue. Optionally, the glue in this embodiment includes but is not limited to optically clear glue (OCA), pressure sensitive glue (PSA), etc.

[0045] As can be seen from the above, the adhesive layer 20 can be bonded to the side of the display component 10 in the folding area 11 to protect the side of the display component 10. On this basis, the present embodiment can make the adhesive layer 20 bonded to the side of the display layer 13 located in the folding area 11, so that the adhesive layer 20 can simultaneously bond the first substrate layer 131 and the second substrate layer 132 (double Pi layer) inside the display layer 13, thereby making the first substrate layer 131 and the second substrate layer 132 connected more closely, preventing the first substrate layer 131 and the second substrate layer 132 from being delaminated, that is, preventing delamination inside the display layer 13.

[0046] Optionally, the display assembly 10 further includes a protection film 16 (Protoction Film PF-protection film 16), which is disposed on the side of the cover layer 14 away from the display layer 13, and the protection film 16 is attached to the cover layer 14, thereby protecting the cover layer 14 and reducing the probability of scratching the cover layer 14, and the protection film 16 can be replaced by itself. Further, optionally, the cover layer 14 protrudes from the protection film 16, thereby preventing the protection film 16 from peeling off due to the misalignment when the display assembly 10 is folded.

[0047] Optionally, when the display component 10 is applied to a mobile phone that folds up and down, the display component 10 may further include a polarizer layer 19 (POL layer), so that the display component 10 has stronger impact resistance and minimizes the reflection intensity of the display component 10 to ambient light.

[0048] Please refer to Figure 5-Figure 6 , Figure 5 It is a cross-sectional schematic diagram of an embodiment of the present application in which an adhesive layer is disposed on a side surface of the display layer and a side surface of the cover layer. Figure 6 The cross-sectional schematic diagram of an adhesive layer disposed on the side of the display layer and the side of the support layer in one embodiment of the present application. In this embodiment, along the arrangement direction of the cover layer 14, the display layer 13, and the support layer 15, the adhesive layer 20 can extend and bond to the side of the cover layer 14 and / or the side of the support layer 15, so that the adhesive layer 20 bonds to the side of the display layer 13 and at least one of the side of the cover layer 14 and the side of the support layer 15.

[0049] Along the arrangement direction of the cover layer 14, the display layer 13, and the support layer 15, the adhesive layer 20 can extend and bond to at least one of the side surfaces of the cover layer 14 and the side surfaces of the support layer 15. In other words, along the thickness direction of the display assembly 10, the adhesive layer 20 can extend to at least one of the side surfaces of the cover layer 14 and the side surfaces of the support layer 15 based on the side surfaces of the display layer 13. That is, the adhesive layer 20 simultaneously bonds and connects the display layer 13 and the cover layer 14, or the adhesive layer 20 simultaneously bonds and connects the display layer 13 and the support layer 15, or the adhesive layer 20 simultaneously bonds and connects the display layer 13, the support layer 15, and the cover layer 14.

[0050] As can be seen from the above, the adhesive layer 20 can be bonded to the side of the display layer 13 located in the folding area 11 to prevent delamination inside the display layer 13. On this basis, the present embodiment can further extend the coverage area of ​​the adhesive layer 20, so that the adhesive layer 20 can simultaneously bond and connect the display layer 13 and the cover layer 14, or the adhesive layer 20 can simultaneously bond and connect the display layer 13 and the support layer 15, or the adhesive layer 20 can simultaneously bond and connect the display layer 13, the support layer 15, and the cover layer 14. In this way, delamination between the display layer 13 and the cover layer 14 or between the display layer 13 and the support layer 15 can be prevented, that is, delamination of the multi-layer structure of the display assembly 10 can be prevented.

[0051] Please refer to Figure 7-Figure 8 , Figure 7 It is a cross-sectional schematic diagram of a support layer protruding from a display layer in one embodiment of the present application. Figure 8 This is a cross-sectional schematic diagram of another embodiment of the present application in which the support layer protrudes from the display layer. In this embodiment, along a direction perpendicular to the arrangement of the cover layer 14, the display layer 13, and the support layer 15, the support layer 15 protrudes from the display layer 13, and the adhesive layer 20 is bonded to the surface of the support layer 15 close to the display layer 13, or the adhesive layer 20 is bonded to the surface of the support layer 15 close to the display layer 13 and the side surface of the support layer 15.

[0052] The supporting layer 15 protrudes from the display layer 13 along the arrangement direction perpendicular to the cover layer 14, the display layer 13, and the supporting layer 15. In other words, along the extension direction of the plane where the display layer 13 is located, the supporting layer 15 protrudes from the display layer 13. In other words, the length and width of the supporting layer 15 are greater than the display layer 13, so that the four sides of the supporting layer 15 all protrude from the display layer 13. The adhesive layer 20 is bonded to the surface of the supporting layer 15 close to the display layer 13, or the adhesive layer 20 is bonded to the surface of the supporting layer 15 close to the display layer 13 and the side of the supporting layer 15. In other words, the adhesive layer 20 is bonded to the side of the display layer 13 and also to the side of the supporting layer 15 that is protruding from the display layer 13. Or the adhesive layer 20 is bonded to the side of the display layer 13, the side of the supporting layer 15 that is protruding from the display layer 13 and the side of the supporting layer 15 at the same time.

[0053] As can be seen from the above, the adhesive layer 20 can be bonded to the side of the display layer 13 located in the folding area 11 to prevent delamination inside the display layer 13. On this basis, in this embodiment, the support layer 15 can be protruded from the display layer 13, and the adhesive layer 20 can also be bonded to the side of the support layer 15 protruding from the display layer 13 facing the display layer 13, or the adhesive layer 20 can be bonded to the side of the support layer 15 protruding from the display layer 13 facing the display layer 13 and the side of the support layer 15. In this way, the adhesive layer 20 can be better bonded to the support layer 15, and during the coating process of the adhesive layer 20, the protruding support layer 15 can carry the adhesive layer 20, preventing the adhesive layer 20 in a liquid state from flowing under the support layer 15, and avoiding the adhesive layer 20 from being bonded and connected to other components.

[0054] Please refer to Fig. 9 , Fig. 9 The cross-sectional schematic diagram of a display assembly including a backplane in one embodiment of the present application. In this embodiment, the display assembly 10 further includes a backplane 17, which is disposed on a side of the support layer 15 away from the display layer 13, and along a direction perpendicular to the arrangement of the cover layer 14, the display layer 13, and the support layer 15, the backplane 17 protrudes from the display layer 13, and the adhesive layer does not protrude from the side of the backplane 17.

[0055] The display assembly 10 may further include a back plate 17 (BKT), which is usually made of a material with a certain hardness to keep the flexible display assembly 10 flat. The material of the back plate 17 includes, but is not limited to, stainless steel, titanium alloy, carbon fiber, and the like. The back plate 17 is disposed on the side of the support layer 15 away from the display layer 13. In other words, the display layer 13, the support layer 15, and the back plate 17 are stacked, and the support layer 15 is closer to the display layer 13 than the back plate 17.

[0056] The back plate 17 protrudes from the display layer 13 along the arrangement direction perpendicular to the cover layer 14, the display layer 13, and the support layer 15. In other words, along the extension direction of the plane where the display layer 13 is located, the back plate 17 protrudes from the display layer 13. In other words, the length and width of the back plate 17 are greater than the display layer 13, so that the four sides of the back plate 17 all protrude from the display layer 13. The adhesive layer 20 does not protrude from the side of the back plate 17. In other words, the back plate 17 protrudes from the adhesive layer 20, or the back plate 17 is horizontal with the adhesive layer 20. Therefore, when the display module 1 is installed in the electronic device 2, the adhesive layer 20 will not protrude from the display component 10, that is, it will not affect the installation of the display module 1.

[0057] Please refer to Fig.10 , Fig.10 2 is a cross-sectional schematic diagram of an embodiment of the present application in which an adhesive layer is disposed on the side of a glass layer. In this embodiment, the display assembly 10 includes a display layer 13, and a cover layer 14 and a support layer 15 bonded to opposite sides of the display layer 13. The cover layer 14 includes a stacked glass layer 142 and a protective layer 141. The glass layer 142 is closer to the display layer 13 than the protective layer 141. The adhesive layer 20 is bonded to the side of the glass layer 142.

[0058] The display assembly 10 includes a display layer 13, a cover layer 14, and a support layer 15. The cover layer 14 and the support layer 15 are bonded to both sides of the display layer 13 by glue. In other words, the cover layer 14 is bonded to one side of the display layer 13 by the glue layer 18, and the support layer 15 is bonded to the other side of the display layer 13 by the glue layer 18. The cover layer 14 includes a stacked glass layer 142 and a protective layer 141 (PL layer). The glass layer 142 and the protective layer 141 are bonded by glue. For example, the glass layer 142 is a 0.03 mm UTG layer, and the protective layer 141 is a 0.05 mm CPI layer. And the glass layer 142 is closer to the display layer 13 than the protective layer 141. In other words, along the arrangement direction of the cover layer 14 and the display layer 13, the protective layer 141, the glass layer 142, and the display layer 13 are arranged in sequence.

[0059] The adhesive layer 20 is bonded to the side of the glass layer 142. In other words, based on the adhesive layer 20 being bonded to the side of the display assembly 10 located in the folding area 11, the present embodiment can also bond the adhesive layer 20 to the side of the glass layer 142 located in the folding area 11. As can be seen from the above, during the manufacturing process of the flexible screen, microcracks may appear in the inorganic material layer when cutting. In the present embodiment, the adhesive layer 20 is bonded to the side of the glass layer 142 located in the folding area 11, so that the adhesive layer 20 can protect the glass layer 142, that is, after the glass layer 142 is cut and microcracks are generated, the microcracks are prevented from further expanding, or other components are prevented from colliding with the glass layer 142 and causing the glass layer 142 to break.

[0060] Please refer to Fig.11 , Fig.11 This is a cross-sectional schematic diagram of another embodiment of the present application in which the adhesive layer is arranged on the side of the glass layer. In this embodiment, along the direction perpendicular to the arrangement of the cover layer 14, the display layer 13, and the support layer 15, the protective layer 141 protrudes from the display layer 13, and the protruding portion of the protective layer 141 is used to be fixed to the folding device 5; the display layer 13 protrudes from the glass layer 142, and one side of the adhesive layer 20 is bonded to the protective layer 141, and the other side is bonded to the display layer 13.

[0061] The protective layer 141 protrudes from the display layer 13 along the arrangement direction perpendicular to the cover layer 14, the display layer 13, and the support layer 15. In other words, along the extension direction of the plane where the display layer 13 is located, the protective layer 141 protrudes from the display layer 13. In other words, the length and width of the protective layer 141 are greater than the display layer 13, so that the four sides of the protective layer 141 all protrude from the display layer 13. The part of the protective layer 141 protruding from the display layer 13 is mainly used to cooperate with the folding device 5, so as to fix the display assembly 10 to the folding device 5.

[0062] The display layer 13 protrudes from the glass layer 142. In other words, along the extension direction of the plane where the display layer 13 is located, the display layer 13 protrudes from the glass layer 142. In other words, the length and width of the display layer 13 are greater than the glass layer 142, so that the four sides of the display layer 13 all protrude from the glass layer 142. One side of the adhesive layer 20 is bonded to the protective layer 141, and the other side is indirectly bonded to the display layer 13 through the glue layer 18. In other words, the adhesive layer 20 is arranged between the protective layer 141 and the display layer 13, and the display layer 13 protrudes from the glass layer 142, and the protective layer 141 protrudes from the display layer 13. As a result, a groove is formed in the layer where the glass layer 142 is located between the display layer 13 and the protective layer 141, and the adhesive layer 20 is arranged in the groove between the protective layer 141 and the display layer 13. Thus, the adhesive layer 20 is bonded to the side of the glass layer 142, protecting the glass layer 142 while filling the gap between the protective layer 141 and the display layer 13, thereby preventing the display component 10 from being broken due to pressing on the edge of the display component 10 during use.

[0063] Please refer to Fig.12 , Fig.12 Schematic diagram of an adhesive layer disposed in a folding area and a non-folding area in one embodiment of the present application. In this embodiment, the display component 10 further has a non-folding area 12, and along the folding direction of the display component 10, the adhesive layer 20 is bonded to the side of the display component 10 located in the non-folding area 12.

[0064] The display assembly 10 also has a non-folding area 12, which is the area on the display assembly 10 other than the folding area 11, and the non-folding area 12 does not bend when the display assembly 10 is bent. As can be seen from the above content, the adhesive layer 20 is bonded to the side of the display assembly 10 located in the folding area 11. On this basis, the present embodiment can also enable the display assembly 10 to have a non-folding area 12, and along the folding direction of the display assembly 10, the adhesive layer 20 is bonded to the side of the display assembly 10 located in the non-folding area 12 and can extend from the folding area 11 to the side of the non-folding area 12. In other words, along the direction perpendicular to the fold in the plane where the display assembly 10 is located, on the basis of the adhesive layer 20 being bonded to the side of the display assembly 10 located in the folding area 11, the adhesive layer 20 can also extend from the side of the display assembly 10 located in the folding area 11 to the side of the display assembly 10 located in the non-folding area 12. As a result, the bonding area of ​​the adhesive layer 20 is larger, the protection range of the side of the display component 10 is wider, and the risk of delamination and edge fragmentation on the side of the display component 10 is further reduced.

[0065] Please refer to Figure 13-14 , Fig.13 This is a schematic diagram of an adhesive layer disposed in a folding area and a non-folding area in another embodiment of the present application. Fig.14 Schematic diagram of another embodiment of the present application in which the adhesive layer is disposed in the folding area and the non-folding area. In this embodiment, along a folding direction perpendicular to the display assembly 10, the adhesive layer 20 is bonded to the side surface of the display assembly 10.

[0066] From the above content, it can be known that the adhesive layer 20 can extend from the side of the display component 10 located in the folding area 11 to the side of the display component 10 located in the non-folding area 12. On this basis, the present embodiment can also make the adhesive layer 20 bonded to the side of the display component 10 along the folding direction perpendicular to the display component 10. In other words, on the basis that the adhesive layer 20 is arranged on the two sides of the display component 10 parallel to the folding direction, the adhesive layer 20 can also continue to extend to the two sides of the display component 10 perpendicular to the folding direction. That is to say, the adhesive layer 20 extends from the two sides of the display component 10 perpendicular to the fold of the display component 10 to the two sides of the display component 10 parallel to the fold of the display component 10. As a result, the adhesive layer 20 is provided on all four sides of the display component 10, so that the adhesive layer 20 covers a larger area of ​​the edge of the display component 10, and the protective effect is better.

[0067] Optionally, the adhesive layer 20 is arranged in a ring shape around the side of the display assembly 10, so that the adhesive layer 20 covers the entire side of the display assembly 10. In other words, the adhesive layer 20 is connected to form a ring shape, so that the adhesive layer 20 has a better protection effect on the edge of the display assembly 10.

[0068] Optionally, the elastic modulus of the adhesive layer 20 parallel to the folding direction is greater than the elastic modulus of the adhesive layer 20 perpendicular to the folding direction, thereby making the adhesive layer 20 perpendicular to the folding direction softer and reducing the influence of the adhesive layer 20 on the folding effect of the display assembly 10.

[0069] Optionally, the thickness of the adhesive layer 20 parallel to the folding direction is greater than the thickness of the adhesive layer 20 perpendicular to the folding direction, so that the adhesive layer 20 perpendicular to the folding direction is more likely to deform, thereby reducing the impact of the adhesive layer 20 on the folding effect of the display assembly 10.

[0070] Please refer to Fig.15 , Fig.15 Schematic diagram of an adhesive layer disposed at a camera hole in one embodiment of the present application. In this embodiment, the display component 10 has a camera hole 30, which penetrates the cover layer 14, the display layer 13 and the support layer 15, and the adhesive layer 20 is disposed on the side of the display component 10 in the camera hole 30. In other words, the adhesive layer 20 can also be disposed on the inner wall of the camera hole 30, so as to protect the side of the display component 10 at the inner edge of the camera hole 30, and prevent the side of the display component 10 on the inner wall of the camera hole 30 from being delaminated or broken.
