[0002] With the development of display technologies, foldable flexible display technologies have attracted increasing attention in the market, and foldable flexible terminal products have gradually entered the consumer market. When a foldable flexible display screen is bent, the hollowed-out part of the support in the display component squeezes the adhesive layer, resulting in different loads transmitted to the display panel when it is flattened, thereby affecting the flatness of the display panel and seriously reducing the user experience. Summary of the Invention

[0003] The purpose of the present disclosure is to provide a display component and a display device that can reduce the film printing on the display panel.

[0004] To achieve the above-mentioned invention purpose, the present disclosure adopts the following technical solutions:

[0005] A first aspect of the present disclosure provides a display component, which includes a display panel, a support, a connecting member, a first adhesive layer, and a second adhesive layer. The display panel includes a bending area and a non-bending area. The support is located on the back of the display panel and is provided with a first groove, and the orthographic projection of the first groove on the display panel is located within the bending area. The connecting member is located within the first groove and includes a plurality of uniformly distributed sub-connecting members, and the orthographic projection of each sub-connecting member on the display panel is located within the bending area. The first adhesive layer is located between the support and the connecting member to bond the support and the connecting member. The second adhesive layer is located between the support and the display panel and covers the connecting member.

[0006] In an implementation manner of the first aspect of the present disclosure, the surface of each sub-connecting member facing the display panel is flush with the surface of the support facing the display panel.

[0007] In an implementation manner of the first aspect of the present disclosure, the shape of the support is strip-shaped, and the first adhesive layer intersects with the sub-connecting members.

[0008] In an implementation manner of the first aspect of the present disclosure, when the shape of the support is strip-shaped, the second adhesive layer intersects with the sub-connecting members.

[0009] In an implementation manner of the first aspect of the present disclosure, the cross-section of the sub-connecting member in the thickness direction of the support is trapezoidal.

[0010] In an implementation manner of the first aspect of the present disclosure, when the cross-section of the sub-connecting member in the thickness direction of the support is trapezoidal, there is no gap between the sub-connecting members.

[0011] In an implementation of the first aspect of the present disclosure, the cross-section of the sub-connectors in the thickness direction of the support member is rectangular, and the sub-connectors are arranged at intervals.

[0012] In an implementation of the first aspect of the present disclosure, when the cross-section of the sub-connector in the thickness direction of the support is trapezoidal, the sub-connector is provided with a second groove; when the display panel is bent, the second glue layer fills the second groove.

[0013] In an implementation of the first aspect of the present disclosure, a cross section of the sub-connector in a thickness direction of the support member is hexagonal, and the sub-connectors are arranged at intervals.

[0014] In an implementation of the first aspect of the present disclosure, the cross-section of the sub-connectors in the thickness direction of the support member is circular, and the sub-connectors are arranged at intervals.

[0015] In an implementation of the first aspect of the present disclosure, the display assembly further includes at least one optical adhesive layer, a film layer, a polarizing layer, and a cover frame.

[0027] 100 - display component; 101 - bending area; 102 - non-bending area; 110 - support member; 111 - first groove; 120 - sub-connector; 130 - first adhesive layer; 140 - second adhesive layer; 150 - display panel; 160 - second groove. Detailed implementation manners

[0028] Now, the exemplary embodiments will be described more comprehensively with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as being limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be more comprehensive and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The features, structures, or characteristics described can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of the embodiments of the present disclosure.

[0029] In the figures, for clarity, the thicknesses of regions and layers may be exaggerated. In the figures, the same reference numerals denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0030] When a structure is “on” another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is “directly” disposed on the other structure, or that the structure is “indirectly” disposed on the other structure through another structure.

[0031] In the display component of a foldable display device, when being bent and twisted, the hollowed-out portion of the support member of the display component extrudes the glue layer. After the glue layer is subjected to the extrusion force, the glue in the glue layer will overflow into the hollowed-out portion of the support member. When the display device is flattened, the glue in the hollowed-out portion of the support member cannot flow back into the glue layer in time. The glue remaining in the hollowed-out portion of the support member will extrude other film layers, thereby causing uneven indentations on the surfaces of other film layers, so that indentations appear in the bending area of the display panel, seriously reducing the user experience.

[0032] Embodiments of the present disclosure provide a display component to at least solve the above technical problems. As Figure 1 shown, the display component 100 may include a display panel 150, a support member 110, a connecting member, a first glue layer 130, and a second glue layer 140. Among them, the display panel 150 may include a bending area 101 and a non-bending area 102. The support member 110 may be located on the back of the display panel 150 and is provided with a first groove 111, and the orthographic projection of the first groove 111 on the display panel 150 is located within the bending area 101. The connecting member may be located in the first groove 111 and may include a plurality of uniformly distributed sub-connecting members 120, and the orthographic projection of each sub-connecting member 120 on the display panel 150 is located within the bending area 101. The first glue layer 130 may be located between the support member 110 and the connecting member to bond the support member 110 and the connecting member. The second glue layer 140 may be located between the support member 110 and the display panel 150 and cover the connecting member.

[0033] In the present disclosure, the support member 110 of the display component 100 may be provided with a first groove 111. The connecting member of the display component 100 may be located within the first groove 111 and may include a plurality of uniformly distributed sub-connecting members 120. When the display component 100 is bent, the adhesive in the second adhesive layer 140 will overflow into the first groove 111 of the support member 110. When the display component 100 is flattened, compared with the design of the entire surface of the support member 110 being hollowed out in the prior art, the design of having a plurality of evenly spaced sub-connecting members 120 in the first groove 111 can reduce the stiffness of the support member 110, improve the elastic deformation ability of the support member 110, and further enable the support member 110 to quickly rebound so that the adhesive remaining in the first groove 111 can quickly flow back into the second adhesive layer 140. Under this design, the extrusion of the adhesive on the display panel 150 can be reduced, and further the indentation of the display panel 150 can be reduced, thereby greatly improving the user experience. In addition, having a plurality of evenly spaced sub-connecting members 120 in the first groove 111 can also greatly improve the anti-bending performance of the display component 100 while improving the elastic deformation ability of the support member 110.

[0034] The following will describe in detail each component of the display component 100 provided by the embodiment of the present disclosure with reference to the accompanying drawings:

[0035] In an embodiment of the present disclosure, the number of the first grooves 111 may be multiple, that is, the first grooves 111 may include a plurality of first sub-grooves. Each first sub-groove is spaced apart, and the orthographic projection of each first sub-groove on the display panel 150 is located within the bending region 101. The plurality of sub-connecting members 120 may be respectively located in the plurality of first sub-grooves, so that each first sub-groove has a plurality of spaced-apart sub-connecting members 120. Under this design, a plurality of sub-connecting members 120 are accommodated in the plurality of first sub-grooves, which can further reduce the stiffness of the support member 110, thereby improving the elastic deformation ability of the support member 110, enabling the support member 110 to quickly rebound, reducing the extrusion of the adhesive on the display panel 150, and further greatly reducing the indentation of the display panel 150.

[0036] It should be noted that the surface of each sub-connecting member 120 in each first sub-groove facing away from the display panel 150 is adhered to the support member 110 through the first adhesive layer 130. And the surface of each sub-connecting member 120 in each first sub-groove facing the display panel 150 is adhered to the display panel 150 through the second adhesive layer 140.

[0037] For example, in at least one embodiment of the present disclosure, the cross-section of the first groove 111 in the thickness direction of the support member 110 is rectangular, and both the connecting member and the first adhesive layer 130 can be accommodated within the first groove 111. It can be understood that the cross-section of the first groove 111 in the thickness direction of the support member 110 can also be other shapes, and no special limitation is made in the present disclosure in this regard.

[0038] In one embodiment of the present disclosure, the surface of each sub-connecting member 120 facing the display panel 150 is flush with the surface of the support member 110 facing the display panel 150. Under this design, it is possible to avoid unevenness on the surface of the support member 110 facing the display panel 150, thereby avoiding extrusion of the second adhesive layer 140. Specifically, each sub-connecting member 120 may include a lower surface facing the display panel 150 and an upper surface facing away from the display panel 150. The support member 110 may include a lower surface facing the display panel 150 and an upper surface facing away from the display panel 150. Among them, the lower surface of each sub-connecting member 120 is flush with the lower surface of the support member 110. That is: the lower surfaces of each sub-connecting member and the support member 110 are in the same plane. It should be noted that when each sub-connecting member 120 is adhered to the support member 110 through the first adhesive layer 130, the lower surface of each sub-connecting member 120 is flush with the lower surface of the support member 110.

[0039] Optionally, the upper surfaces between each sub-connecting member 120 are flush. That is: the upper surfaces between each sub-connecting member 120 are in the same plane. Under this design, it is convenient to adhere the support member 110 and the connecting member through the first adhesive layer 130.

[0040] In one embodiment of the present disclosure, as Figure 2As shown, the support member 110 can be in a strip structure. The first adhesive layer 130 and the sub-connector 120 can be arranged crosswise. In this design, the crosswise arranged first adhesive layer 130 and sub-connector 120 can improve the resilience of the sub-connector 120. That is, after being bent, the sub-connector 120 can quickly rebound to its original shape, so that the adhesive material remaining in the first groove 111 can flow back to the second adhesive layer 140 in time, thereby avoiding the adhesive material from extruding other film layers and causing indentations on the display panel 150, which in turn affects the user experience. Specifically, the number of the first adhesive layers 130 can be multiple, and the shape of each first adhesive layer 130 can be in a strip structure, and the shape of each sub-connector 120 can be in a strip structure. Each sub-connector 120 is arranged crosswise with each first adhesive layer 130 so that all the sub-connectors 120 and all the first adhesive layers 130 form a woven pattern. Among them, the sub-connectors 120 are evenly spaced, and the first adhesive layers 130 are evenly spaced. In this way, when the woven pattern formed by the sub-connectors 120 and the first adhesive layers 130 is bent, the force is evenly distributed, avoiding stress concentration in the connectors.

[0041] For example, in at least one embodiment of the present disclosure, the second adhesive layer 140 and the sub-connector 120 can be arranged crosswise. In this design, the crosswise arranged second adhesive layer 140 and sub-connector 120 can improve the resilience of the support member 110. That is, after being bent, the support member 110 can quickly rebound and return to its original shape. Since the support member 110 and the display panel 150 are bonded by the second adhesive layer 140, the quickly rebounding support member 110 can reduce the extrusion on the display panel 150, thereby reducing the indentation on the display panel 150. Specifically, the number of the second adhesive layers 140 can be multiple, and the shape of each second adhesive layer 140 can be in a strip structure, and the shape of each sub-connector 120 can be in a strip structure. The sub-connector 120 and the second adhesive layer 140 are arranged crosswise so that all the sub-connectors 120 and all the second adhesive layers 140 form a woven pattern. Among them, the sub-connectors 120 are evenly spaced, and the second adhesive layers 140 are evenly spaced. In this way, when the woven pattern formed by the sub-connectors 120 and the second adhesive layers 140 is bent, the force is evenly distributed, avoiding stress concentration in the support member 110.

[0042] In one embodiment of the present disclosure, as Figure 3As shown, the cross-section of the sub-connector 120 in the thickness direction of the support member 110 can be a trapezoidal structure, and there is no gap between the sub-connectors 120. Under this design, the connection area between the sub-connector 120 and the second adhesive layer 140 can be reduced. Thus, when bending, the extrusion force of the sub-connector 120 on the second adhesive layer 140 can be reduced by reducing the extrusion area of the sub-connector 120 on the second adhesive layer 140, so that the shape of the sub-connector 120 can be prevented from being imprinted on other film layers. Specifically, the sub-connector 120 can have a short side close to the display panel 150 and a long side facing away from the display panel 150, and the short sides of the sub-connectors 120 are flush with each other, and the long sides of the sub-connectors 120 are flush with the surface of the support member 110 close to the display panel 150.

[0043] Optionally, the size of the short side of the sub-connector 120 is not greater than half of the size of the long side of the sub-connector 120. For example, the size of the short side of the sub-connector 120 is L1, and the size of the long side of the sub-connector 120 is L2. The dimensional requirement between the short side and the long side of the sub-connector 120 is L1 ≤ L2 / 2.

[0044] In another embodiment of the present disclosure, as Figure 4 shown, the support member 110 can include a plurality of sub-connectors 120 having a trapezoidal structure. The sub-connectors 120 are spaced apart from each other, and the orthographic projection of each sub-connector 120 on the display panel 150 is located within the bending region 101. It should be noted that the support member 110 is not provided with the first groove 111, but directly a plurality of sub-connectors 120 having a trapezoidal structure are provided in the portion of the support member 110 located in the bending region 101. Under this design, the connection area between the sub-connector 120 and the second adhesive layer 140 can also be reduced. Thus, when bending, the extrusion force of each sub-connector 120 on the second adhesive layer 140 can be reduced by reducing the extrusion area of the sub-connector 120 on the second adhesive layer 140, so that the shape of the sub-connector 120 can be prevented from being imprinted on other film layers.

[0045] In another embodiment of the present disclosure, as Figure 5 shown, the cross-section of the sub-connector 120 in the thickness direction of the support member 110 is rectangular, and the sub-connectors 120 are spaced apart from each other. Each sub-connector 120 is provided with a second groove 160, and the opening of the second groove 160 is in contact with the second adhesive layer 140. Under this design, after bending, a part of the adhesive in the second adhesive layer 140 can overflow into the second groove 160, so as to reduce the amount of adhesive entering the gap between the sub-connectors 120. When unfolding, a part of the adhesive remaining in the second groove 160 can flow back into the second adhesive layer 140 in time, so as to avoid squeezing other film layers, thereby improving the flatness of the display panel 150.

[0046] In another embodiment of the present disclosure, as Figure 6 shown, the cross-section of the sub-connector 120 in the thickness direction of the support 110 is hexagonal, and the sub-connectors 120 are spaced apart. Since the connection area between the surface of the hexagonal sub-connector 120 facing away from the display panel 150 and the first adhesive layer 130 is small, and the connection area between the surface of the sub-connector 120 facing the display panel 150 and the first adhesive layer 130 is also small, therefore, in this design, the connection area between the sub-connector 120 and the first adhesive layer 130 and the second adhesive layer 140 can be reduced. Thus, when bending, the extrusion force of the sub-connector 120 on the first adhesive layer 130 and the second adhesive layer 140 can be further reduced by reducing the extrusion area of the sub-connector 120 on the first adhesive layer 130 and the second adhesive layer 140, so that the imprint of the shape of the sub-connector 120 on other film layers can be significantly reduced.

[0047] In another embodiment of the present disclosure, as Figure 7 shown, the cross-section of the sub-connector 120 in the thickness direction of the support 110 is circular, and the sub-connectors 120 are spaced apart. Since the connection area between the surface of the circular sub-connector 120 facing away from the display panel 150 and the first adhesive layer 130 is smaller than that of the hexagonal sub-connector 120, and the connection area between the surface of the sub-connector 120 facing the display panel 150 and the first adhesive layer 130 is also smaller than that of the hexagonal sub-connector 120, therefore, in this design, the connection area between the sub-connector 120 and the first adhesive layer 130 and the second adhesive layer 140 can be further reduced. Thus, when bending, the extrusion force of the sub-connector 120 on the first adhesive layer 130 and the second adhesive layer 140 can be further reduced by reducing the extrusion area of the sub-connector 120 on the first adhesive layer 130 and the second adhesive layer 140, so that the imprint of the shape of the sub-connector 120 on other film layers can be significantly reduced.

[0048] In an embodiment of the present disclosure, the display component 100 may further include at least one optical adhesive layer, a thin film layer, a polarizing layer, and a cover plate frame. Among them, the thin film layer may be located between the second adhesive layer 140 and the display panel 150; the polarizing layer may be located on the side of the display panel 150 facing away from the thin film layer and adhered to the display panel 150 through an optical adhesive layer; the cover plate frame may be located on the side of the polarizing layer facing away from the display panel 150 and adhered to the polarizing layer through an optical adhesive layer. Using the support member 110 provided by the embodiment of the present disclosure to attach the thin film layer can reduce the extrusion of the support member 110 on the thin film layer, thereby reducing the extrusion of the adhesive on the display panel 150, and further reducing the indentation of the display panel 150, thus greatly improving the user experience. In addition, a plurality of uniformly spaced sub-connectors 120 are provided in the first groove 111, which can greatly improve the anti-bending performance of the display component 100 while improving the elastic deformation ability of the support member 110.

[0049] Optionally, the display component 100 may further include a touch layer, and the touch layer is located between the polarizing layer and the display panel 150; among them, the touch layer may be attached to the polarizing layer through an optical adhesive layer, and the touch layer is in contact with the display panel 1500 or attached to the display panel 150 through an optical adhesive layer. Specifically, the touch layer can enable the display device to have a touch function, and the user can use the sliding of a finger or a stylus to control the display function of the display panel 150. For example, the touch layer may also be set to include a pressure sensing film layer (such as a metal grid), etc., so as to have a three-dimensional touch function.

[0050] Optionally, the display component 100 may further include an array substrate, a display function layer formed on the array substrate, and a packaging layer covering the display function layer. When manufacturing the touch layer, the touch layer can be directly formed on the packaging layer through processes such as film deposition and patterning. In this way, it is beneficial to the thin and light design of the entire display device.

[0051] Optionally, the cover plate frame may include a first sub-cover plate frame and a second sub-cover plate frame. The second sub-cover plate frame and the first sub-cover plate frame are sequentially stacked on the side of the polarizing layer facing away from the display panel and adhered to each other by an optical adhesive layer. The first sub-cover plate and the second sub-cover plate are adhered together through an optical adhesive layer, and the second sub-cover plate is adhered to the polarizing layer through an optical adhesive layer. The design of the first sub-cover plate and the second sub-cover plate can further improve the protection of the display device to reduce the risk of the display device being impacted, broken, or scratched, and increase the reliability of the display device.

[0052] In an embodiment of the present disclosure, a display device is further provided. The display device includes any one of the display components 100 described in the above-described embodiment of the display component 100. The display device may be a smartphone screen, a computer monitor, a digital camera photo frame, a tablet computer, an electronic painting screen, an electronic billboard, or other types of display devices. Since the display device has any one of the display components 100 described in the above-described embodiment of the display component 100, it has the same beneficial effects, which will not be elaborated herein in the present disclosure.
