[0016] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0017] Please also read Figure 1 and Figure 2 In one embodiment of the present application, a support component 100 is provided, including a bending area 101 and non-bending areas 102 located on both sides of the bending area 101. The support component 100 can be bent in the bending area 101. The support component 100 includes a first support plate 103, a first adhesive layer 104 and a second support plate 105.

[0018] The first support plate 103 is provided with at least one groove 1031 located in the bending area 101 . The groove 1031 is used to provide a deformation space for the first support plate 103 when it is bent or folded, which is beneficial to the release of internal stress.

[0019] The first adhesive layer 104 is disposed on one side of the first support plate 103 , and the first adhesive layer 104 is used to adhere the second support plate 105 to the first support plate 103 .

[0020] The second support plate 105 is disposed on the side of the first adhesive layer 104 away from the first support plate 103, and includes a first support portion 1051 located in the bending area 101 and a second support portion 1052 located in the non-bending area 102, and the second support portion 1052 is located on both sides of the first support portion 1051 and is spaced apart from the first support portion 1051. That is, the first support portion 1051 does not completely cover the bending area 101, and / or the second support portion 1052 does not completely cover the non-bending area 102.

[0021] In the above-mentioned support assembly 100, by providing the first support portion 1051 and the second support portion 1052 spaced apart on the first support plate 103, and providing the first support portion 1051 in the bending zone 101, the support assembly 100 can reduce the bending stress generated by the second support plate 105 when being bent, thereby reducing the risk of the bonding state between the first support plate 103, the first adhesive layer 104 and the second support plate 105 being damaged by internal stress. At the same time, the second support portion 1052 is provided in the non-bending zone 102, for supporting the display module in the non-bending zone 102, reducing the risk of deformation of the display module 200 in the non-bending zone 102, and improving the reliability of the display module 200.

[0022] See also Figure 1In one embodiment, the groove 1031 located in the bending area 101 may be, for example, a strip-shaped groove, and the present application does not limit the shape of the groove 1031. Optionally, there may be multiple grooves 1031 on the bending area 101, and the multiple grooves 1031 are distributed in an array along the direction X from the non-bending area 102 to the bending area 101, so that the first support plate 103 can obtain a larger deformation space when bending or folding, which is conducive to the release of internal stress and reduces the internal stress of each layer structure of the support assembly 100.

[0023] In one embodiment, the number of the grooves 1031 may be one or more, which is set according to actual needs and is not specifically limited in this application.

[0024] In one embodiment, the groove 1031 can be formed on the first support plate 103 by using a laser cutting or etching process.

[0025] See also Figure 2 In one embodiment, the first support plate 103 and the second support plate 105 are made of the same material, which can reduce the manufacturing cost of the support assembly 100 .

[0026] In other embodiments, the materials of the first support plate 103 and the second support plate 105 may also be different. For example, the material of the first support plate 103 includes titanium alloy, and the material of the second support plate 105 includes stainless steel.

[0027] In this embodiment, the material of the first support plate 103 and the second support plate 105 includes stainless steel to improve the structural strength of the entire support assembly 100. At the same time, stainless steel has good elongation, so it can better adapt to the needs of repeated flattening and folding of the display module 200, reducing the risk of breakage or difficulty in bending.

[0028] Please continue reading Figure 2 In one embodiment, the interval between the second support portion 1052 and the first support portion 1051 is disposed outside the bending zone 101. The above arrangement reduces the risk of the interval between the first support portion 1051 and the second support portion 1052 being broken due to stress because the interval between the first support portion 1051 and the second support portion 1052 is not directly exposed to the repeated bending action of the bending zone 101.

[0029] In one embodiment, the interval between the second support portion 1052 and the first support portion 1051 is located in the non-bending area 102. The above arrangement enables the interval between the first support portion 1051 and the second support portion 1052 to be away from the bending area 101, further reducing the risk of the interval between the first support portion 1051 and the second support portion 1052 being broken due to stress.

[0030] Please refer again Figure 1 and Figure 2 In one embodiment, the first adhesive layer 104 includes a first adhesive portion 1041 located in the bending area 101 and a second adhesive portion 1042 located in the non-bending area 102. The second adhesive portion 1042 is located on both sides of the first adhesive portion 1041 and is spaced apart from the first adhesive portion 1041.

[0031] Through the above-mentioned arrangement, the first adhesive layer 104 adopts a segmented design, and at least part of the bending zone 101 is not provided with the first adhesive portion 1041, and / or at least part of the non-bending zone 102 is not provided with the second adhesive portion 1042, that is, the first adhesive portion 1041 does not completely cover the bending zone 101, and / or the second adhesive portion 1042 does not completely cover the non-bending zone 102. This can reduce to a certain extent the risk of cracks caused by excessive compression of the bending zone 101 due to bending stress when the support component 100 is folded or bent.

[0032] In one embodiment, the material of the first adhesive layer 104 includes OCA adhesive (Optically Crystal Adhesive, optical adhesive).

[0033] Please continue reading Figure 1 and Figure 2 In one embodiment, in the direction X pointing from the non-bending area 102 to the bending area 101, the width D1 of the first adhesive portion 1041 is smaller than the width D2 of the bending area 101, so that the first support plate 103 can have a larger deformation space in the bending area 101, so the internal stress generated by the support component 100 in the bending area 101 is smaller, which is beneficial to reducing the overall stress of the support component 100 when folded or bent.

[0034] Please continue reading Figure 1 and Figure 2 In this embodiment, the second glue portion 1042 is provided on both sides of the first glue portion 1041, so that when the support assembly 100 is bent or folded, the second glue portions 1042 on both sides of the first glue portion 1041 apply the same or similar forces to the first support plate 103, which is beneficial to improving the bending reliability of the support assembly 100.

[0035] Please continue reading Figure 1 and Figure 2 In one embodiment, in the direction X from the non-bending area 102 to the bending area 101, the second adhesive portion 1042 is retracted relative to the second supporting portion 1052. When the support component 100 is bent or folded, the risk of the second adhesive portion 1042 extending relative to the first supporting plate 103 and overflowing outside the non-bending area 102 is reduced, thereby further helping to improve the bending reliability of the support component 100.

[0036] Please continue reading Figure 1 and Figure 2In one embodiment, in the direction X from the non-bending area 102 to the bending area 101, the width D1 of the first adhesive portion 1041 is smaller than the width of the second adhesive portion 1042, thereby reducing the lateral bending stress generated by the first adhesive portion 1041 when the support component 100 is bent or folded.

[0037] In one embodiment, the width D1 of the first adhesive portion 1041 is in the range of 5-10 cm, for example, the width D1 of the first adhesive portion 1041 is 5 cm, 7.5 cm or 10 cm.

[0038] In one embodiment, the width of the second adhesive portion 1042 is in the range of 20-30 cm, for example, the width of the second adhesive portion 1042 is 20 cm, 25 cm or 30 cm.

[0039] Please also read Figure 2 and Figure 3 In one embodiment, the orthographic projection of the first support portion 1051 on the first support plate 103 covers the orthographic projection of the first adhesive portion 1041 on the first support plate 103. That is, the orthographic projection of the first support portion 1051 and the first adhesive portion 1041 on the first support plate 103 can be completely overlapped, or the orthographic projection of the first adhesive portion 1041 on the first support plate 103 is located within the orthographic projection of the first support portion 1051 on the first support plate 103, which reduces the bending stress generated by the bending or folding of the support assembly 100, and can also improve the buffering and supporting effects of the first support portion 1051 in the thickness direction Y of the first support plate 103.

[0040] In this embodiment, the orthographic projection of the first support portion 1051 on the first support plate 103 extends beyond the orthographic projection of the first adhesive portion 1041 on the first support plate 103. That is, the first adhesive portion 1041 is retracted relative to the first support portion 1051, thereby improving the overall stiffness of the support assembly 100. The increase in stiffness can reduce the creases generated by the folding of the support assembly 100, and can also reduce the risk of the first adhesive portion 1041 extending to the outside of the first support portion 1051 due to the bending stress when the support assembly 100 is bent.

[0041] In one embodiment, the width D3 of the first support portion 1051 is in the range of 8-13 cm, for example, the width D3 of the first support portion 1051 is 8 cm, 10 cm or 13 cm.

[0042] Please continue reading Figure 2 and Figure 3In one embodiment, the orthographic projection of the second support portion 1052 on the first support plate 103 covers the orthographic projection of the second adhesive portion 1042 on the first support plate 103. That is, the orthographic projection of the second support portion 1052 and the second adhesive portion 1042 on the first support plate 103 can be completely overlapped, or the orthographic projection of the second adhesive portion 1042 on the first support plate 103 is located within the orthographic projection of the second support portion 1052 on the first support plate 103, which reduces the bending stress generated by the bending or folding of the support assembly 100, and can also improve the buffering and supporting effects of the second support portion 1052 in the thickness direction Y of the first support plate 103.

[0043] In this embodiment, the orthographic projection of the second support portion 1052 on the first support plate 103 extends beyond the orthographic projection of the second adhesive portion 1042 on the first support plate 103. That is, the second adhesive portion 1042 is retracted relative to the second support portion 1052, thereby improving the overall stiffness of the support assembly 100. The increase in stiffness can reduce the creases generated by the folding of the support assembly 100, and can also reduce the risk of the second adhesive portion 1042 extending to the outside of the second support portion 1052 due to the bending stress when the support assembly 100 is bent.

[0044] In one embodiment, the width of the second support portion 1052 is in the range of 25-35 cm, for example, the width of the second support portion 1052 is 25 cm, 30 cm or 35 cm.

[0045] Please continue reading Figure 2 and Figure 3 In one embodiment, the outer edge of the first adhesive layer 104 is flush with the outer edge of the second support plate 105 , thereby reducing the risk of the first adhesive layer 104 overflowing from the second support plate 105 .

[0046] In another embodiment, the outer edge of the first adhesive layer 104 may not be flush with the outer edge of the second support plate 105 . For example, the outer edge of the first adhesive layer 104 is retracted relative to the outer edge of the second support plate 105 .

[0047] Please continue reading Figure 2 and Figure 3 In one embodiment, in a direction parallel to the first support plate 103, the first support plate 103 extends beyond the first adhesive layer 104, so that the first support plate 103 can protect the edge of the first adhesive layer 104, thereby reducing the risk of scratches and abrasions on both sides of the first adhesive layer 104 caused by external collisions.

[0048] In another embodiment, in a direction parallel to the first support plate 103 , the outer edge of the first support plate 103 may also be flush with the outer edge of the first adhesive layer 104 .

[0049] Please refer again Figure 1 and Figure 2, in one embodiment, the support assembly 100 further includes a second glue layer 106 , which is disposed on the side of the second support plate 105 facing away from the first support plate 103 . The support assembly 100 may be bonded with other structures of the display module 200 through the second adhesive layer 106 to form a display module 200 of the complete folding screen device.

[0050] In one embodiment, the second glue layer 106 is the same material as the first glue layer 104 , which can reduce the production cost of the support assembly 100 . For example, the materials of the first adhesive layer 104 and the second adhesive layer 106 include OCA adhesive (Opt ica lly C learAdhes ive).

[0051] In another embodiment, the second adhesive layer 106 and the first adhesive layer 104 may also be made of different materials.

[0052] Please refer again Figure 2 , in one embodiment, the second glue layer 106 includes a third glue portion 1061 located in the bending region 101 and a fourth glue portion 1062 located in the non-bending region 102 , and the fourth glue portion 1062 is located on both sides of the third glue portion 1061 and is disposed at a distance from the third glue portion 1061 .

[0053] The fourth glue portion 1062 is arranged in the non-bending area 102 to adhere to the side of the second support plate 105 facing away from the second rubber portion 1042, so that when the support assembly 100 is bent or folded, the forces applied by the two fourth glue portions 1062 to the second support plate 105 are the same or similar, which is conducive to improving the bending reliability of the support assembly 100.

[0054] Please refer again Figure 2 and Figure 3 In one embodiment, the orthographic projection of the first support portion 1051 on the first support plate 103 covers the orthographic projection of the third adhesive portion 1061 on the first support plate 103. That is, the orthographic projections of the first support portion 1051 and the third adhesive portion 1061 on the first support plate 103 can be completely overlapped, or the orthographic projection of the third adhesive portion 1061 on the first support plate 103 is located within the orthographic projection of the first support portion 1051 on the first support plate 103, which reduces the bending stress generated by the bending or folding of the support assembly 100, and can also improve the buffering and supporting effects of the first support portion 1051 in the thickness direction Y of the first support plate 103.

[0055] In this embodiment, the orthographic projection of the first support portion 1051 on the first support plate 103 extends beyond the orthographic projection of the third adhesive portion 1061 on the first support plate 103. That is, the third adhesive portion 1061 is retracted relative to the first support portion 1051, which can improve the overall stiffness of the support assembly 100. The increase in stiffness can reduce the creases generated by the folding of the support assembly 100, and also reduce the risk of the third adhesive portion 1061 extending to the outside of the first support portion 1051 due to the bending stress when the support assembly 100 is bent.

[0056] In one embodiment, the width D4 of the third adhesive portion 1061 is in the range of 6-11 cm, for example, the width D4 of the third adhesive portion 1061 is 6 cm, 8.5 cm or 11 cm.

[0057] Please continue reading Figure 2 and Figure 3 In one embodiment, the orthographic projection of the second support portion 1052 on the first support plate 103 covers the orthographic projection of the fourth adhesive portion 1062 on the first support plate 103. That is, the orthographic projections of the second support portion 1052 and the fourth adhesive portion 1062 on the first support plate 103 can be completely overlapped, or the orthographic projection of the fourth adhesive portion 1062 on the first support plate 103 is located within the orthographic projection of the second support portion 1052 on the first support plate 103, which reduces the bending stress generated by the bending or folding of the support assembly 100, and can also improve the buffering and supporting effects of the second support portion 1052 in the thickness direction Y of the first support plate 103.

[0058] In this embodiment, the orthographic projection of the second support portion 1052 on the first support plate 103 extends beyond the orthographic projection of the fourth adhesive portion 1062 on the first support plate 103. That is, the fourth adhesive portion 1062 is retracted relative to the second support portion 1052, which can improve the overall stiffness of the support assembly 100. The increase in stiffness can reduce the creases generated by the folding of the support assembly 100, and can also reduce the risk of the fourth adhesive portion 1062 extending to the outside of the second support portion 1052 due to the bending stress when the support assembly 100 is bent.

[0059] In one embodiment, the width of the fourth adhesive portion 1062 is in the range of 22-32 cm, for example, the width of the fourth adhesive portion 1062 is 22 cm, 26 cm, or 32 cm.

While the third adhesive portion 1061 achieves buffering and supporting functions, it can also further improve the extensibility of the support assembly 100 in the direction X from the non-bending area 102 to the bending area 101, thereby reducing the risk of bending stress generated by the support assembly 100 when it is bent or folded.

[0061] Please continue reading Figure 2 and Figure 3 In one embodiment, the orthographic projection of the fourth adhesive portion 1062 on the first support plate 103 covers and extends beyond the orthographic projection of the second adhesive portion 1042 on the first support plate 103, that is, the fourth adhesive portion 1062 is extended relative to the second adhesive portion 1042. While the fourth adhesive portion 1062 achieves buffering and supporting functions, it can also further improve the extensibility of the support assembly 100 in the direction X from the non-bending area 102 to the bending area 101, thereby reducing the risk of bending stress generated by the support assembly 100 when it is bent or folded.

[0062] Please continue reading Figure 2 and Figure 3 In one embodiment, the outer edge of the second adhesive layer 106 is flush with the outer edge of the second support plate 105 , thereby reducing the risk of the second adhesive layer 106 overflowing from the second support plate 105 .

[0063] In another embodiment, the outer edge of the second adhesive layer 106 may not be flush with the outer edge of the second support plate 105 , for example, the second adhesive layer 106 is retracted relative to the second support plate 105 .

[0064] Please refer again Figure 1 In one embodiment, the support assembly 100 further includes an electrostatic protection layer 107, which is disposed on the side of the second adhesive layer 106 away from the first support plate 103. The electrostatic protection layer 107 can improve the electrostatic dissipation capability of the support assembly 100, thereby improving the uneven brightness (Mura) of the bending area 101.

[0065] Please continue reading Figure 1 In one embodiment, the material of the electrostatic protection layer 107 includes a conductive material. The conductive material can be selected from materials with low density, light weight and high strength, for example, the conductive material includes at least one of graphite sheet, carbon fiber and copper foil, so that the weight of the support assembly 100 can be reduced.

[0066] Please continue reading Figure 1The present application also provides a display module 200, comprising a display panel 300 and the above-mentioned support assembly 100, wherein the support assembly 100 is located on the backlight side of the display panel 300, and the display panel 300 is located on the side of the second support plate 105 away from the first support plate 103. The support assembly 100 is used to support the display panel 300, improve the situation where the display panel 300 is prone to bending stress when being bent or folded, thereby improving the reliability of the display module 200.

[0067] Please continue reading Figure 1 In one embodiment, the display module 200 further includes a protective layer 400, which is connected to the side of the display panel 300 away from the supporting assembly 100, that is, the protective layer 400 is connected to the light-emitting side of the display panel 300.

[0068] In one implementation, the material of the protective layer 400 may include glass, and the present application does not impose any specific limitation on the material of the protective layer 400 .

[0069] It is understandable that the protection layer 400 can be any feasible film structure that is attached to the display panel 300 and is away from the surface of the support assembly 100 and has no stickiness, as long as it can protect the display panel 300 .

[0070] It should be noted that the display module 200 provided in the embodiment of the present invention can be embodied as any product or component with a display function, such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, etc.
