[0073] In order to better understand this application, Figures 1 to 11 The display device and the supporting assembly 100 according to the embodiment of the present application are described in detail.

[0074] Please also read Figures 1 to 4 , Figure 1 A schematic diagram of the structure of a display device provided in accordance with an embodiment of the first aspect of the present application. Figure 2 is a top view of a display device provided by an embodiment of the first aspect of the present application; Figure 31 is a schematic structural diagram of a support assembly 100 of a display device in a flattened state provided by an embodiment of the first aspect of the present application. Figure 2 It is a partial cross-sectional view of a display device provided in an embodiment of the first aspect of the present application.

[0075] like Figures 1 to 4 As shown, on one hand, an embodiment of the present application provides a display device, the display device having a plane area M and a bending area Q located on at least one side of the plane area M, the display device comprising: a support assembly 100, comprising a support layer 110 and a first adhesive layer 120 stacked on each other; a display panel 200, arranged on a side of the first adhesive layer 120 away from the support layer 110, wherein the support assembly 100 and the display panel 200 both extend from the plane area M to the bending area Q, and a cutout 130 is provided on the support layer 110, and the cutout 130 is located in the bending area Q.

[0076] In the display device of the embodiment of the present application, the display device has a plane area M and a bending area Q, and the display device is bent in the bending area Q. The display device includes a support assembly 100 and a display panel 200, the support assembly 100 includes a support layer 110 and a first adhesive layer 120, the support assembly 100 provides a support force to the display panel 200 through the support layer 110, and the support layer 110 and the display panel 200 are mutually bonded through the first adhesive layer 120. The display panel 200 is used to realize the display function of the display device. The support layer 110 is provided with a cutout 130 located in the bending area Q. By providing the cutout 130, the rigidity of the support layer 110 at the position of the cutout 130 can be reduced, so that the support layer 110 is convenient to bend and deform according to the bending demand, so as to improve the bonding yield of the support layer 110 and the display panel 200 in the bending area Q. It should be noted that the display device of the present disclosure may not be a terminal product, such as a mobile phone, a computer, etc. Of course, the display device may also be a terminal product.

[0077] Optionally, the display device further includes a cover plate 300, which is disposed on a side of the display panel 200 away from the support assembly 100. The cover plate 300 extends from the plane area M to the bending area Q.

[0078] See also Figure 5In the display device provided in the related art, when the cutout 130' is not provided on the support component 100', the support component 100' in the bending area Q will be deformed during the actual bonding process. After bonding with the display panel 200', the length of the surface of the support component 100' close to the display panel 200' will be greater than the length of the surface away from the display panel 200', resulting in the surface of the support component 100' facing the display panel 200' being stretched, while the surface of the side away from the display panel 200' is contracted, which may cause a poor bonding gap between the support component 100' and the display panel 200', and a poor bonding wrinkle on the side of the support component 100' away from the display panel 200'. All of these defects may cause the display device to have poor display such as halo and mold printing.

[0079] In the display panel 200 provided in the embodiment of the present application, since the support layer 110 of the support assembly 100 is provided with the cutout 130, the stiffness of the support layer 110 in the bending region Q can be reduced, making the support layer 110 more susceptible to deformation, thereby improving the poor fitting gap caused by the bending rebound stress of the support layer 110 itself. In addition, when the support layer 110 is bent, the cutout 130 can be deformed, for example, the opening size of the cutout 130 is increased, etc., which can release the volume deformation caused by the extrusion of the surface of the side of the support assembly 100 away from the substrate in the bending region Q, thereby improving the wrinkle defect.

[0080] Optionally, the incision 130 can be formed by directly cutting a portion of the support layer 110 using a cutter. Figure 6 As shown, the cutout 130 includes two side walls 130a disposed opposite to each other, one end of the two side walls 130a is connected to each other, and the other end is disposed opposite to each other and separated from each other to form an opening of the cutout 130. Optionally, as Figure 3 As shown, the support assembly 100 has a flattened state, and in the flattened state, the two side walls 130a of the cutout 130 can be arranged in contact with each other. The cutout 130 is different from the groove. The groove needs to remove part of the material of the support layer 110 to form. In the flattened state, the inner walls of the groove are spaced apart from each other but not in contact with each other. Optionally, before the support assembly 100 is not attached to the cover plate 300, the support assembly 100 can be in a flattened state. After the support assembly 100 and the display panel 200 are attached to one side of the cover plate 300 to form a display device, at least a portion of the support assembly 100 can be in a bent state, for example, the portion of the support assembly 100 located in the bending area Q is in a bent state.

[0081] In some optional embodiments, the support component 100 has a flattened state, in which the cutout 130 has a preset depth in a preset direction, and a first angle is formed between the preset direction and the thickness direction of the support component 100. Optionally, the first angle is not 0. That is, the extension direction of the cutout 130 intersects with the thickness direction of the support component 100, and the cutout 130 does not extend along the thickness direction, which can improve the problem of the support layer 110 being cut during the preparation process and improve the preparation yield of the support layer 110.

[0082] In some optional embodiments, the support layer 110 has a bottom surface 112 and a support surface 111 disposed opposite to each other, and the first adhesive layer 120 is disposed on the support surface 111. The support layer 110 can support the display panel 200 through the support surface 111.

[0083] There are many ways to set the cutout 130. For example, when the bending area Q is bent toward the backlight side of the display panel 200, the opening of the cutout 130 is set on the support surface 111, that is, the opening of the cutout 130 is connected to the support surface 111, and the cutout 130 is extended from the support surface 111 toward the bottom surface 112. When the support assembly 100 is transformed from the flat state to the bent state, the stretching of the support surface 111 can be absorbed by the opening size of the cutout 130, thereby improving the problem of the easy occurrence of a fitting gap between the support surface 111 and the display panel 200.

[0084] Optionally, the side of the display panel 200 facing away from the support assembly 100 is the light emitting side, and the side of the display panel 200 facing the support assembly 100 is the backlight side. When the bending area Q bends toward the backlight side of the display panel 200, the display panel 200 folds outward to increase the external display area of ​​the display device.

[0085] In some other optional embodiments, the opening of the cutout 130 is provided on the bottom surface 112, that is, the opening of the cutout 130 is connected to the bottom surface 112, and the bending area Q is bent toward the light-emitting side of the display panel 200. When the support assembly 100 is transformed from the flat state to the bent state, the opening of the cutout 130 can be increased to absorb the stretching of the bottom surface 112, thereby improving the problem of the fitting gap between the support surface 111 and the display panel 200, and can also absorb the shrinkage deformation of the support surface 111, thereby improving the problem of fitting wrinkles on the support surface 111.

[0086] When the bending area Q bends toward the light emitting side of the display panel 200, the display panel 200 is folded inwards. That is, when the display panel 200 is folded outwards, the cutout 130 extends from the support surface 111 toward the bottom surface 112, and when the display panel 200 is folded inwards, the cutout 130 extends from the bottom surface 112 toward the support surface 111.

[0087] The embodiment of the present application is described by taking the bending area Q bending toward the backlight side of the display panel 200 as an example.

[0088] In some optional embodiments, such as Figure 2 As shown, the cutout 130 is in a strip shape, and the cutout 130 is arranged parallel to at least a portion of the boundary of the plane area M.

[0089] In these optional embodiments, the strip shape of the cutout 130 means that the extension shape of the cutout 130 in the surface where the support surface 111 is located is strip-shaped. The cutout 130 is parallel to at least part of the boundary of the plane area M, so that the cutout 130 can improve the poor fitting problem near at least part of the boundary of the plane area M.

[0090] Optionally, the bending area Q is arranged along a preset track around the plane area M, and the cutout 130 is extended along the preset track. The cutout 130 and the bending area Q extend along the same track, so that the cutout 130 can improve the poor fitting at different positions in the bending area Q.

[0091] For example, when the bending area Q is arranged along a circular track around the plane area M, the cutout 130 may also be arranged along a circular track around the plane area M, so that the cutout 130 can improve the poor fitting at different positions in the bending area Q. When the bending area Q is located on at least one side of the plane area M, for example, when the bending area Q is located on one side of the plane area M in the first direction and extends along the second direction, the cutout 130 may also be extended and formed along the second direction.

[0092] Alternatively, when the number of the bending regions Q is two and the two bending regions Q are disposed on opposite sides of the plane region M, the same cutout 130 may include two sub-segments, each of which is located at each bending region Q.

[0093] Optionally, the number of the cutouts 130 may be one or more. When the number of the cutouts 130 is multiple, the multiple cutouts 130 are arranged at intervals along the direction from the plane area M to the bending area Q. By providing multiple cutouts 130, the rigidity of the support layer 110 can be better reduced and the stiffness of the support layer 110 can be improved.

[0094] In some optional embodiments, the bending area Q is bent toward the backlight side of the display panel 200, and the outer peripheral surface of the support component 100 includes a first edge 101 close to the display panel 200 and a second edge 102 away from the display panel 200; the orthographic projection of the first edge 101 on the display panel 200 is located on the side of the orthographic projection of the second edge 102 on the display panel 200 close to the plane area M. After the support component 100 is bent, due to the presence of the cutout 130, in order to adapt to the bending deformation, the surface of the support component 100 close to the display panel 200 will be stretched, and the surface away from the display panel 200 will be compressed, thereby making the surface away from the display panel 200 extend relative to the surface close to the display panel 200, so that the second edge 102 is arranged away from the plane area M relative to the first edge 101.

[0095] In some optional embodiments, such as Figure 6 As shown, the incision 130 is filled with the adhesive portion 121. Optionally, when the opening of the incision 130 faces the first adhesive layer 120, the adhesive portion 121 and the first adhesive layer 120 are integrally formed.

[0096] In these optional embodiments, when the support assembly 100 changes from a flattened state to a bent state, the opening size of the incision 130 gradually increases, and part of the material of the first adhesive layer 120 can overflow into the incision 130 to form a bonding portion 121, which can improve the bonding strength between the support layer 110 and the display panel 200 and improve the problem of holes in the incision 130 caused by the excessive opening size of the incision 130.

[0097] In some optional embodiments, a lubricant (not shown in the figure) may be filled in the cutout 130. When the support assembly 100 is transformed from a flat state to a bent state, the presence of the lubricant makes it easy for the two side walls 130a of the cutout 130 to be relatively displaced, thereby making it easier for the support layer 110 to be deformed, thereby better improving poor lamination.

[0098] In some optional embodiments, such as Figure 7 and Figure 8 As shown, the support layer 110 may include a support conductive layer 110a, and the cutout 130 includes a first cutout 131 disposed in the support conductive layer 110a. In addition, the bending area Q is bent toward the backlight side of the display panel 200, and the angle between the outer peripheral surface of the support assembly 100 and the display panel 200 is an acute angle.

[0099] In these optional embodiments, the supporting conductive layer 110a has conductive properties, so that the supporting conductive layer 110a can release static electricity of the display panel 200 and improve the performance of the display device. The material of the supporting conductive layer 110a can be a metal material, so that the supporting conductive layer 110a has a good supporting effect.

[0100] Optionally, the supporting conductive layer 110a may be a copper foil layer, so that the supporting conductive layer 110a has not only good supporting performance but also good conductive performance.

[0101] In some other optional embodiments, the support layer 110 may further include a support buffer layer 110 b , and the cutout 130 may include a second cutout 132 disposed in the support buffer layer 110 b .

[0102] In these optional embodiments, the supporting buffer layer 110 b has a good buffering effect, which can improve the stress of the display panel 200 and enhance the performance of the display device.

[0103] The material of the support buffer layer 110 b can be selected from at least one of instant noodles and polyimide, so that the support buffer layer 110 b can not only provide good support but also have good buffering performance.

[0104] There are many ways to arrange the support layer 110, and the support layer 110 may be a single-layer film structure. In this case, the support layer 110 may include the above-mentioned support conductive layer 110a or support buffer layer 110b.

[0105] In some other optional embodiments, the support layer 110 may also include more than two film layers, for example, the support layer 110 may include both the support conductive layer 110a and the support buffer layer 110b. When the support layer 110 includes the support conductive layer 110a and the support buffer layer 110b, the support buffer layer 110b is located on the side of the support conductive layer 110a facing the display panel 200, so that the support buffer layer 110b can better improve the stress of the display panel 200.

[0106] When the supporting buffer layer 110b is located on the side of the supporting conductive layer 110a facing the display panel 200, the supporting surface 111 is disposed on the side of the supporting buffer layer 110b facing the display panel 200, and the first adhesive layer 120 is disposed between the supporting buffer layer 110b and the display panel 200. The bottom surface 112 is located on the side of the supporting conductive layer 110a away from the supporting buffer layer 110b, and a second adhesive layer 140 may be further disposed between the supporting conductive layer 110a and the supporting buffer layer 110b to improve the stability of the relative position between the supporting conductive layer 110a and the supporting buffer layer 110b.

[0107] Optionally, when the first cutout 131 is provided on the supporting conductive layer 110a and the second cutout 132 is provided on the supporting buffer layer 110b, the first cutout 131 and the second cutout 132 are staggered along the thickness direction of the supporting component 100 to improve the overall supporting performance of the supporting layer 110. The first cutout 131 and the second cutout 132 are staggered along the thickness direction of the supporting component 100, which means that the orthographic projection of the top of the first cutout 131 on the supporting buffer layer 110b is arranged at an order interval with the second cutout 132.

[0108] Optionally, when the incision 130 is filled with the adhesive portion 121 , the adhesive portion 121 in the first incision 131 and the second adhesive layer 140 are integrally formed, and / or the adhesive portion 121 in the second incision 132 and the first adhesive layer 120 are integrally formed.

[0109] In some optional embodiments, such as Figures 7 to 10 As shown, the bending region Q may include a first bending region Q1 and a second bending region Q2, the curvature of the first bending region Q1 is greater than the curvature of the second bending region Q2, and / or the thickness of the support layer 110 in the first bending region Q1 is greater than the thickness of the support layer 110 in the second bending region Q2. For example, the curvature of at least one of the cover plate 300, the display panel 200, and the support assembly 100 in the first bending region Q1 is greater than the curvature of the second bending region Q2.

[0110] Optionally, cutouts 130 are provided in both the first bending area Q1 and the second bending area Q2 to improve poor fitting in different bending areas Q.

[0111] Optionally, the first bending region Q1 and the second bending region Q2 are distributed in a direction away from the plane region M, and the first bending region Q1 may be located on the side of the second bending region Q2 facing toward or away from the plane region M. That is, along the direction away from the plane region M, the curvature of the bending region Q may gradually increase or decrease, or the curvature of the bending region Q may gradually increase and then gradually decrease, or the curvature of the bending region Q may gradually decrease and then gradually increase.

[0112] Optional, such as Fig. 9 As shown, the cutout 130 has a preset depth, and the preset depth of the cutout 130 located in the first bending zone Q1 is greater than the preset depth of the cutout 130 located in the second bending zone Q2.

[0113] For example, the curvature of the first bending zone Q1 is greater than that of the second bending zone Q2. The curvature of the first bending zone Q1 is larger. When the support layer 110 changes from a flat state to a bent state, the deformation in the first bending zone Q1 is larger. A cutout 130 with a preset depth is set in the first bending zone Q1, which can improve the deformation ability of the support layer 110 in the first bending zone Q1 and better improve poor fitting.

[0114] And / or, the thickness of the supporting layer 110 in the first bending zone Q1 is greater than the thickness of the supporting layer 110 in the second bending zone Q2, that is, the greater the thickness of the supporting layer 110 and the deeper the depth of the incision 130, the better the structural rigidity of the supporting layer 110 can be improved, making it easier for the supporting layer 110 to bend as the display panel 200 bends.

[0115] Optional, such as Fig.10 As shown, the first bending zone Q1 and the second bending zone Q2 are both provided with a plurality of cutouts 130 , and the distribution density of the cutouts 130 located in the first bending zone Q1 is greater than the distribution density of the cutouts 130 located in the second bending zone Q2 .

[0116] Optionally, the multiple cutouts 130 in the first bending area Q1 and the second bending area Q2 are distributed at intervals along the direction from the plane area M to the bending area Q.

[0117] In these optional embodiments, for example, the curvature of the first bending zone Q1 is relatively large, and when the support layer 110 changes from a flat state to a bent state, the deformation in the first bending zone Q1 is relatively large. A cutout 130 with a relatively large distribution density is provided in the first bending zone Q1, which can improve the deformation ability of the support layer 110 in the first bending zone Q1 and better improve poor fitting.

[0118] And / or, the thickness of the support layer 110 in the first bending zone Q1 is relatively large, and a large distribution density of cutouts 130 is provided in the first bending zone Q1, which can improve the deformation ability of the support layer 110 in the first bending zone Q1 and better improve poor fitting.

[0119] Optionally, when the distribution density of the cutouts 130 in the first bending zone Q1 is relatively high, the distance between at least two adjacent cutouts 130 in the first bending zone Q1 is smaller than the distance between two adjacent cutouts 130 in the second bending zone Q2.

[0120] Optional, such as Fig.11 As shown, in the flattened state, the cutout 130 has a preset depth in a preset direction, the angle between the preset direction and the thickness direction of the support assembly 100 is a first angle, and the first angle in the first bending zone Q1 is smaller than the first angle in the second bending zone Q2. That is, in the flattened state, the angle between the depth direction (i.e., the preset direction) and the thickness direction of the cutout 130 in the first bending zone Q1 is smaller than the angle between the depth direction and the thickness direction of the cutout 130 in the second bending zone Q2.

[0121] When the angle between the depth direction and the thickness direction of the cutout 130 is small, in the bent state, the stress on the support layer 110 at the location of the cutout 130 is smaller, and the deformation ability of the support layer 110 at the location of the cutout 130 is better.

[0122] In the embodiment of the present application, the first angle in the first bending zone Q1 is smaller than the first angle in the second bending zone Q2, that is, when the curvature is greater, or the thickness of the support layer 110 is greater, the angle between the extension direction of the incision 130 and the thickness direction is smaller, so that the support layer 110 in the first bending zone Q1 has better deformation ability and can better improve the problem of poor fitting.

[0123] Optionally, the first angle is not 0, for example, the first angle is 5°, 10°, etc. When the cutout 130 extends along the thickness direction, the support layer 110 is easily cut off during the preparation of the cutout 130, resulting in a fracture of the support layer 110. The first angle is not 0, which can improve the preparation yield of the support layer 110.

[0124] In some optional embodiments, the preset depth of the incision 130 is less than or equal to half of the thickness of the support layer 110. For example, the preset depth of the incision 130 is equal to 9 / 24, 11 / 24, etc. of the thickness of the support layer 110, so as to improve the problem that the preset depth of the incision 130 is too large, which affects the structural strength of the support layer 110 itself and causes the support layer 110 to be easily broken.

[0125] The preset depth of the cutout 130 may be an extension dimension L2 of the cutout 130 in the thickness direction. For example, the extension dimension of the cutout 130 in the preset direction is L1, the first angle is a, and L2 satisfies the following relationship: L2=L1*cos a.

[0126] Optionally, the preset depth of the cutout 130 may also be the extension dimension of the cutout 130 in a preset direction, that is, the preset depth of the cutout 130 is L1, and L1 is less than or equal to half of the thickness of the support layer 110.

[0127] Optionally, when multiple incisions 130 are spaced apart and distributed in the direction from the plane area M to the bending area Q, the distance between two adjacent incisions 130 is greater than or equal to 0.1 mm. For example, the distance may be 0.2 mm, 0.5 mm, etc., so as to improve the problem that the distribution density of the incisions 130 is too small and the spacing between two adjacent incisions 130 is too small, which affects the structural strength of the support layer 110 and makes the support layer 110 prone to breakage.

[0128] like Figures 1 to 11As shown, the embodiment of the second aspect of the present application further provides a support assembly 100, and the support assembly 100 is used to support the display panel 200 of the display device.

The support assembly 100 includes: a support layer 110, having a bottom surface 112 and a support surface 111 arranged opposite to each other along the thickness direction of the support assembly 100; a first adhesive layer 120, arranged on the side where the support surface 111 of the support layer 110 is located; wherein the support layer 110 and the first adhesive layer 120 both extend from the first area N to the second area P, and a cutout 130 is arranged on the support layer 110, and the cutout 130 is located in the second area P.

[0131] Optionally, the bending area Q is arranged around the plane area M along a preset trajectory, and the corresponding second area P is arranged around the plane area M along a preset trajectory. The incision 130 is extended and formed along the preset trajectory so that the incision 130 can improve the poor fitting at different positions within the bending area Q.

[0132] Optionally, the number of the cutouts 130 may be one or more. When the number of the cutouts 130 is multiple, the multiple cutouts 130 are arranged at intervals along the direction from the plane area M to the bending area Q. That is, the multiple cutouts 130 are arranged at intervals along the direction from the first area N to the second area P.

[0133] Optionally, as mentioned above, the incision 130 is filled with the adhesive portion 121 ; and / or the incision 130 is filled with a lubricant.

[0134] In some embodiments, the support layer 110 may include the support conductive layer 110 a and / or the support buffer layer 110 b described above.

[0135] In some optional embodiments, please refer to the above, the bending area Q includes a first bending area Q1 and a second bending area Q2, and correspondingly, the second area P may include a first sub-area P1 and a second sub-area P2, the first sub-area P1 is used to support the display panel 200 in the first bending area Q1, and the second sub-area P2 is used to support the display panel 200 in the second bending area Q2, that is, in the display device, the first sub-area P1 is located in the first bending area Q1, and the second sub-area P2 is located in the second bending area Q2. The curvature of the first bending area Q1 is greater than the curvature of the second bending area Q2, and / or the thickness of the support layer 110 in the first sub-area P1 is greater than the thickness of the support layer 110 in the second sub-area P2.

[0136] Optionally, the first sub-region P1 and the second sub-region P2 are both provided with a cutout 130 , so that the cutout 130 can improve the bonding yield of the first sub-region P1 , the second sub-region P2 and the display panel 200 .

[0137] Optionally, the cutout 130 has a preset depth, and the preset depth of the cutout 130 in the first sub-region P1 is greater than the preset depth of the cutout 130 in the second sub-region P2, so as to improve the deformation ability of the first sub-region P1, so that the first sub-region P1 can better adapt to the first bending zone Q1 with a larger curvature.

[0138] Preferably, the first sub-region P1 and the second sub-region P2 are both provided with a plurality of cutouts 130, and the distribution density of the cutouts 130 in the first sub-region P1 is greater than the distribution density of the cutouts 130 in the second sub-region P2, so as to improve the deformation capacity of the first sub-region P1, so that the first sub-region P1 can better adapt to the first bending zone Q1 with a larger curvature.

[0140] Optionally, the first angle is not 0. When the cutout 130 extends along the thickness direction, the support layer 110 is easily cut off during the preparation of the cutout 130, resulting in a fracture of the support layer 110. The first angle is not 0, which can improve the preparation yield of the support layer 110.

[0141] Optionally, the opening directions of the cutouts 130 in the first sub-region P1 and the second sub-region P2 are the same, so that the cutouts 130 in the first sub-region P1 and the second sub-region P2 can cooperate to reduce the stiffness of the support layer 110 .

[0142] like Figures 1 to 11 As shown, the embodiment of the second aspect of the present application further provides a support assembly 100, which is used to support the display panel 200 of the display device. The display device can be the display device of any of the above-mentioned first aspect embodiments, and the support assembly 100 can be the support assembly 100 of the display device of any of the above-mentioned first aspect embodiments. For example, the display device has a plane area M and a bending area Q located on at least one side of the plane area M, and the support component 100 has a first area N corresponding to the plane area M and a second area P corresponding to the bending area Q, that is, the support component 100 includes the first area N and the second area P, and the second area P is located on the outer peripheral side of the first area N.

[0143] When the bending stiffness of the portion of the support layer 110 located in the second area P is smaller than the bending stiffness of the portion of the support layer 110 located in the first area N, the force applied to bend the portion of the support layer 110 located in the second area P to the first curvature is smaller than the force applied to bend the portion of the support layer 110 located in the first area N to the first curvature, that is, the smaller the bending stiffness is, the smaller the force required to bend to the preset curvature is, and the easier it is to bend.

[0144] In the support assembly 100 provided in the embodiment of the present application, the support assembly 100 includes a support layer 110 and a first adhesive layer 120.
