DETAILED DESCRIPTION

[0044] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0045] In the related art, flexible devices are widely used in high-end fields such as wearables, mobile phones, tablets, and computers because they have larger screens and better portability and adaptability. Devices that can be bent to a smaller radius and have almost no permanent deformation after multiple bends are expected by more and more people. Flexible display panels are generally formed by stacking multiple film layers with specific functions. When subjected to external loads such as tension, bending and compression, the compressive stress will cause buckling including wrinkling, creases and warping, resulting in unstable deformation of the device. The failure caused by the external load will seriously affect the conductivity and structural integrity of the flexible display panel, which is very unfavorable to the flexible display panel. Among them, the adhesive layer corresponding to the bendable part of the flexible display panel will be stretched outward by extrusion when folded, and accumulate in the area near the bendable part, resulting in increased strain, especially along the folding direction, and the greater the thickness of the adhesive layer, the wider the accumulation area. Due to the flow of the material of the adhesive layer, the area near the bendable part of the adhesive layer can accumulate to form a hump shape and undergo permanent deformation. During the long folding process, due to the extrusion of the adhesive layer, in severe cases, the functional layer film of the display panel may be damaged by extrusion, shearing or delamination, thus affecting the display effect. Therefore, it is very important to effectively prevent the device from creases under external loads to ensure the safe and reliable operation of the flexible display panel.

[0046] like Figures 1 to 9 As shown, the present application provides a display panel 1, comprising:

[0047] The display panel 1 includes a bendable portion 11 and a non-bendable portion 12 connected to the bendable portion 11. The display panel 1 includes:

[0048] Cover plate 13;

[0049] Display component 14;

[0050] The first adhesive layer 15 is disposed between the cover plate 13 and the display assembly 14 . The first adhesive layer 15 has a groove 151 corresponding to the bendable portion 11 .

[0051] The embodiment of the present application provides a display panel 1, the display panel 1 has a bendable portion 11 and a non-bending portion 12, the bendable portion 11 is a portion that can be bent, the non-bending portion 12 is a portion that does not bend, the bendable portion 11 is connected to the non-bending portion 12, so that the display panel 1 is bent at the bendable portion 11, which can drive the non-bending portion 12 to be in different positions, so that the display panel 1 has different states. The display panel 1 includes a stacked cover plate 13, a first adhesive layer 15 and a display assembly 14, the first adhesive layer 15 is arranged between the cover plate 13 and the display assembly 14, the first adhesive layer 15 bonds the cover plate 13 to the display assembly 14, so that the cover plate 13 can be covered outside the display assembly 14, for protecting the display assembly 14, and can display the display content of the display assembly 14. In the first adhesive layer 15, the first adhesive layer 15 has an area corresponding to the bendable portion 11 and the non-bending portion 12, and the first adhesive layer 15 has a groove 151 at the bendable portion 11. When the bendable portion 11 of the display panel 1 is bent, the groove 151 provided on the first adhesive layer 15 corresponding to the bendable portion 11 can provide additional space for the material to stretch, so that when the bendable portion 11 of the display panel 1 is bent, the tensile stress of the material can be reduced, so that the stress can be dispersed over a larger volume. At the same time, the groove 151 provided on the first adhesive layer 15 corresponding to the bendable portion 11 also changes the path of stress transmission in the material, forcing the stress to bypass the groove 151 area, thereby reducing the stress directly in the bending area. The hump-shaped deformation at the bendable portion 11 is avoided, thereby reducing the probability of wrinkles, creases or warping of the bendable portion 11 of the display panel 1.

[0052] Therefore, the display panel 1 provided in the present application has a groove 151 disposed at the first adhesive layer 15 corresponding to the bendable portion 11, thereby improving the bending performance of the display panel 1, enhancing the bending durability and flatness of the display panel 1, and improving the user experience. At the same time, the probability of the display panel 1 being damaged due to bending is avoided, and the bending life of the display panel 1 is enhanced.

[0053] like Figures 1 to 9 As shown, in the embodiment of the present application, the light emitting direction of the display panel 1 is a first direction;

[0054] The display panel 1 may be bent in a first direction, and the opening of the groove 151 may face the first direction; or, the display panel 1 may be bent in a second direction, and the opening of the groove 151 may also face the second direction, and the second direction may be opposite to the first direction.

[0055] In this embodiment, the display panel 1 can emit light, and the light emitting direction can be a first direction, and the first direction can be a direction approximately perpendicular to the surface of the display panel 1 when the display panel 1 is in a flat state. The display panel 1 can be bent in the first direction or in a second direction opposite to the first direction. The display panel 1 includes a bendable portion 11 and a non-bending portion 12. In the display panel 1, the bendable portion 11 is an area where the display panel 1 can be bent. The non-bending portion 12 is an area where the display panel 1 cannot be bent.

[0056] like Figure 1 As shown, in one embodiment of the present application, the display panel 1 can be an inward folding screen, in which case the first adhesive layer 15 in the display panel 1 and the groove 151 corresponding to the bendable portion 11 face the first direction, so that the display panel 1 can be bent toward the first direction of the bendable portion 11. During the bending process, the first adhesive layer 15 can be provided with a groove 151 opening toward the first direction, so that when bending toward the first direction, the groove 151 can provide additional space for the material of the display panel 1 to stretch, so that when the bendable portion 11 of the display panel 1 is bent, the tensile stress of the material can be reduced, so that the stress can be dispersed over a larger volume. At the same time, the groove 151 corresponding to the bendable portion 11 on the first adhesive layer 15 also changes the path of stress transmission in the material, forcing the stress to bypass the groove 151 area, thereby reducing the stress directly formed in the bending area, avoiding the formation of a hump-shaped deformation at the bendable portion 11, and thus avoiding the display panel 1 from wrinkling, creases or warping when folding inward.

[0057] like Figure 1 As shown, in another embodiment of the present application, the display panel 1 can be an external folding screen, in which case the first adhesive layer 15 in the display panel 1 and the groove 151 corresponding to the bendable portion 11 face the second direction, so that the display panel 1 can be bent toward the second direction of the bendable portion 11. During the bending process, the first adhesive layer 15 can be provided with a groove 151 opening toward the second direction, so that when bending toward the second direction, the groove 151 can provide additional space for the material of the display panel 1 to stretch, so that when the bendable portion 11 of the display panel 1 is bent, the tensile stress of the material can be reduced, so that the stress can be dispersed over a larger volume. At the same time, the groove 151 corresponding to the bendable portion 11 on the first adhesive layer 15 also changes the path of stress transmission in the material, forcing the stress to bypass the groove 151 area, thereby reducing the stress directly formed in the bending area, avoiding the formation of a hump-shaped deformation at the bendable portion 11, and thus avoiding the display panel 1 from wrinkling, creases or warping when folding outward.

[0058] like Figure 2 As shown, in the embodiment of the present application, it may also include:

[0059] The flexible member 16 may be located in the groove 151 and may be connected to the cover plate 13 or the display assembly 14 .

[0060] In this embodiment, the display panel 1 may include a cover plate 13, a first adhesive layer 15, a display component 14 and a flexible member 16. The first adhesive layer 15 is arranged between the cover plate 13 and the display component 14, and is used to connect the display component 14 and the cover plate 13. The display panel 1 includes a bendable portion 11 and a non-bendable portion 12. The first adhesive layer 15 has an area corresponding to the bendable portion 11 and the non-bendable portion 12. A groove 151 may be arranged on the first adhesive layer 15 in the area corresponding to the bendable portion 11. A flexible member 16 may be arranged in the groove 151. The flexible member 16 can fill at least part of the groove 151 and can be connected to the cover plate 13 or the display component 14 facing the groove 151. The molecular structure of the flexible parts 16 allows them to deform under the action of external force, and then return to their original shape after the external force is removed. Therefore, when the display panel 1 is bent, the flexible parts 16 are deformed and play a buffering role, thereby further avoiding the occurrence of wrinkles, creases or warping in the bendable portion 11 of the display panel 1.

[0061] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, the display panel 1 can be an inward folding screen. At this time, the first adhesive layer 15 in the display panel 1 and the groove 151 corresponding to the bendable portion 11 are facing in a first direction, and the first direction is the direction of the first adhesive layer 15 toward the cover plate 13. A flexible member 16 can be provided in the groove 151 of the first adhesive layer 15. The flexible member 16 can also be connected to the side of the cover plate 13 facing the first adhesive layer 15, and corresponding to the position of the groove 151, the flexible member 16 extends into the groove 151 to fill the groove 151. The flexible member 16 can be an organic transparent material. The organic transparent material located in the groove 151 can play a buffering role, thereby further improving the ability of the cover plate 13 to resist bending and folding, and further avoiding wrinkles, creases or warping on the bendable portion 11 of the cover plate 13.

[0062] like Figure 1 and Figure 2As shown, in another embodiment of the present application, the display panel 1 can be an external folding screen. At this time, the first adhesive layer 15 in the display panel 1 and the groove 151 corresponding to the bendable portion 11 are facing in a second direction, and the second direction is the direction of the first adhesive layer 15 toward the display component 14. A flexible member 16 can be provided in the groove 151 of the first adhesive layer 15. The flexible member 16 can also be connected to the side of the display component 14 facing the first adhesive layer 15, and corresponding to the position of the groove 151, the flexible member 16 extends into the groove 151 to fill the groove 151. The flexible member 16 can be an organic transparent material. The organic transparent material located in the groove 151 can play a buffering role, thereby further improving the ability of the display component 14 to resist bending and folding, and further avoiding wrinkles, creases or warping on the bendable portion 11 of the display component 14.

[0063] like Figure 1 As shown, in another embodiment of the present application, the first adhesive layer 15 can be thinned at the corresponding bendable portion 11, so that the thinned portion can form a groove 151 on the first adhesive layer 15, and the depth of the groove can be, for example, between 0-10um, but the present application is not limited thereto, thereby reducing the area where stress is concentrated during the bending process, thereby further improving the bending performance and avoiding the probability of creases.

[0064] like Figure 1 and Figure 2 As shown, in another embodiment of the present application, the first adhesive layer 15 can be thinned at the corresponding bendable portion 11, so that the thinned portion can form a groove 151 on the first adhesive layer 15, and the depth of the groove can be, for example, between 0-10um, but the present application is not limited to this, and a flexible member 16 connected to the cover plate 13 is provided at the corresponding groove 151, so that the groove 151 and the flexible member 16 can further improve the bending performance and avoid the probability of creases.

[0065] In the embodiment of the present application, the display panel may further include:

[0066] The rigid member may be located in the groove 151 and may be connected to the cover plate 13 or the display assembly 14 .

[0067] In this embodiment, the display panel 1 may include a cover plate 13, a first adhesive layer 15, a display assembly 14 and a rigid member, the first adhesive layer 15 is arranged between the cover plate 13 and the display assembly 14, and is used to connect the display assembly 14 and the cover plate 13, the display panel 1 includes a bendable portion 11 and a non-bending portion 12, the first adhesive layer has an area corresponding to the bendable portion 11 and the non-bending portion 12, a groove 151 is arranged on the area corresponding to the bendable portion 11 of the first adhesive layer 15, and a rigid member is arranged in the groove 151, the rigid member fills at least part of the groove 151, and is connected to the cover plate 13 or the display assembly 14 facing the groove 151. The rigid member can be a transparent inorganic material, such as silicon nitride (SiNx) and silicon oxide (SiOx), etc., which is characterized by providing sufficient hardness. They have higher hardness and rigidity and are not easy to bend, so as to provide better protection performance for the display panel 1, so that they can be used in equipment requiring high protection and structural stability.

[0068] like Figure 3 As shown, in the embodiment of the present application, the bottom wall of the groove 151 may have one or more sub-recesses 1511; and / or,

[0069] The inner wall of the groove 151 may be a curved surface.

[0070] In one embodiment of the present application, the display panel 1 may include a cover plate 13, a first adhesive layer 15 and a display component 14. The first adhesive layer 15 is arranged between the cover plate 13 and the display component 14, and is used to connect the display component 14 and the cover plate 13. The display panel 1 may include a bendable portion 11 and a non-bendable portion 12. The first adhesive layer has an area corresponding to the bendable portion 11 and the non-bendable portion 12. The area of ​​the first adhesive layer 15 corresponding to the bendable portion 11 is thinned relative to the non-bendable portion 12 to form a groove 151 on the first adhesive layer 15. The bottom wall of the groove 151 may have a sub-recessed portion 1511, which may be correspondingly arranged on the axis of the bendable portion 11. The sub-recessed portion 1511 located on the axis can make the dispersed stress more uniform, thereby making the bending effect of the display panel 1 more symmetrical.

[0071] like Figure 3 As shown, in another embodiment of the present application, the first adhesive layer 15 can be thinned relative to the non-bending portion 12 in the area corresponding to the bendable portion 11 to form a groove 151, and the bottom wall of the groove 151 can have a plurality of sub-recesses 1511, and the plurality of sub-recesses 1511 can be evenly spaced, so that stress can be dispersed in more locations, thereby further reducing the probability of creases or deformations.

[0072] like Figure 3 and Figure 4As shown, in another embodiment of the present application, the first adhesive layer 15 can be thinned relative to the non-bending portion 12 in the area corresponding to the bendable portion 11, so as to form a groove 151 in the area corresponding to the first adhesive layer 15 and the bendable portion 11, and the bottom wall of the groove 151 can have a plurality of sub-recesses 1511, and the plurality of sub-recesses 1511 are evenly spaced, and a flexible member 16 is arranged in the groove 151 of the first adhesive layer 15, and the flexible member 16 is also connected to the display component 14 toward the side of the first adhesive layer 15, so that the stress can be dispersed in more positions, thereby further reducing the probability of creases or deformation.

[0073] like Figure 5 As shown, in another embodiment of the present application, the first adhesive layer 1 can be thinned relative to the non-bending portion 12 in the area corresponding to the bendable portion 11, so as to form a groove 151 on the area corresponding to the first adhesive layer 15 and the bendable portion 11, and the bottom wall of the groove 151 can have a plurality of sub-recesses 1511, and the plurality of sub-recesses 1511 are evenly spaced. A flexible member 16 is arranged in the groove 151 of the first adhesive layer 15, and the flexible member 16 is also connected to the display component 14 toward the side of the first adhesive layer 15, and the flexible member 16 is connected to the display component 14. 6 has a certain thickness along the thickness direction of the display panel 1, which is used to supplement the reduced thickness of the first adhesive layer to avoid a large height difference, and a flexible protrusion filling the groove 151 is provided on the side facing the groove 151. The flexible member 16 is an organic transparent material. The flexible member 16 located in the groove 151 and the flexible member 16 with a certain thickness can play a buffering role, thereby further improving the ability of the display component 14 to resist bending and folding, and further avoiding wrinkles, creases or warping of the bendable portion 11 of the display component 14.

[0074] like Figure 1 and Figure 3 As shown, in another embodiment of the present application, the inner wall of the groove 151 that can be set in the area corresponding to the first adhesive layer 15 and the bendable portion 11 can be a curved surface, that is, the edge of the groove 151 can be in a smooth state, and the edge of the groove 151 in a smooth state can disperse stress more effectively than a sharp edge, avoiding the formation of new stress concentration points, thereby further reducing the probability of creases.

[0075] In the embodiment of the present application, the first adhesive layer 15 has a hollow area 18 corresponding to the bendable portion 11, and the hollow area 18 forms a groove 151. The display panel 1 may further include:

[0076] The second adhesive layer 19 may be disposed in the groove 151 , and the modulus of the second adhesive layer 19 may be smaller than the modulus of the first adhesive layer 15 .

[0077] like Figure 6 and Figure 7As shown, in this embodiment, the display panel 1 may include a cover plate 13, a first adhesive layer 15, a display component 14 and a second adhesive layer 19. The first adhesive layer 15 is used to be arranged between the cover plate 13 and the display component 14, and is used to connect the cover plate 13 to the display component 14. The display panel 1 may have a bendable portion 11 and a non-bendable portion 12. The first adhesive layer 15 has areas corresponding to the bendable portion 11 and the non-bendable portion 12. The first adhesive layer 15 may have a hollow area 18 at the bendable portion 11 corresponding to the first adhesive layer 15. The hollow area 18 is the groove 151 of the first adhesive layer 15, so that the groove 151 can have different shapes according to the shape of the hollow area 18, so as to meet more bending requirements. The groove 151 is also filled with a second adhesive layer 19, which is liquid glue or pressure-sensitive adhesive (PSA). The modulus of the second adhesive layer 19 is smaller than that of the first adhesive layer 15. The modulus refers to the ratio of stress to strain of a material under stress. The modulus of the second adhesive layer 19 is smaller than that of the first adhesive layer 15, which means that the ability of the second adhesive layer 19 to resist elastic deformation under external force is smaller than that of the first adhesive layer 15. Therefore, the second adhesive layer 19 arranged in the groove 151 is more likely to be deformed under external force than the first adhesive layer 15, that is, the first adhesive layer 15 is relatively hard and not easy to be deformed under external force, while the second adhesive layer is softer than the second adhesive layer 19 and is more likely to be deformed under external force. Therefore, when bending occurs, the characteristics of the second adhesive layer 19 enable the integrity of the material to be better maintained when bent or stretched, thereby reducing damage and improving the bending performance of the display panel 1.

[0078] like Figure 6 As shown, in the embodiment of the present application, the display panel may further include:

[0079] A first release film 20, which may be disposed on one side of the first adhesive layer 15;

[0080] A second release film 21, which may be disposed on the other side of the first adhesive layer away from the first release film 20;

[0081] When the first adhesive layer is connected to the cover plate 13 and the display assembly 14 , the first release film 20 and the second release film 21 may be removed.

[0082] In this embodiment, when the first adhesive layer 15 is not used to bond the display assembly 14 and the cover plate 13, the first surface and the second surface of the first adhesive layer 15 may be respectively provided with a first release film 20 and a second release film 21 to protect the first adhesive layer 15. When the display panel 1 is assembled and installed, the first release film 20 and the second release film 21 on the first surface and the second surface of the first adhesive layer 15 may be removed first, and then the first adhesive layer 15 may be disposed on the display assembly 14 to be connected to the display assembly 14, and then the cover plate 13 may be covered on the side of the first adhesive layer 15 that is away from the display assembly 14, so that the cover plate 13 and the display assembly 14 are connected through the first adhesive layer 15. Therefore, when the display panel 1 is not installed, the first adhesive layer 15 may be protected by the first release film 20 and the second release film 21 to prevent the first adhesive layer 15 from being damaged.

[0083] In the embodiment of the present application, the groove 151 may be a rectangular groove 151;

[0084] Furthermore, the groove 151 may penetrate the first adhesive layer along the thickness direction of the display panel 1 .

[0085] In this embodiment, the display panel 1 may include a cover plate 13, a first adhesive layer 15 and a display component 14. The first adhesive layer 15 is used to be arranged between the cover plate 13 and the display component 14 to connect the cover plate 13 and the display component 14. The display panel 1 may have a bendable portion 11 and a non-bendable portion 12. The first adhesive layer 15 has an area corresponding to the bendable portion 11 and the non-bendable portion 12. The first adhesive layer 15 has a groove 151 at the bendable portion 11. The groove 151 penetrates the first adhesive layer 15 along the thickness direction of the display panel 1 to form the first adhesive layer 15 into a segmented structure, thereby providing more additional space for the material to stretch, thereby further reducing the tensile stress of the material when bending occurs, further improving the bending performance, and improving the bending performance of the display panel 1.

[0086] like Figure 6 and Figure 7 As shown, in the embodiment of the present application, the groove 151 may pass through along the length direction of the bendable portion 11; or

[0087] The groove 151 may have at least part of the first bonding block 22 at both ends along the length of the bendable portion 11;

[0088] The first adhesive block 22 is a portion of the first adhesive layer 15 .
