[0041] In the following, the technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work should belong to the protection scope of the present application.

[0042] It should be noted that the terms "first", "second" and the like in the description and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in other than the order illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a list of steps or units need not be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to such processes, methods, products or devices.

[0043] Figure 1 A bottom structure schematic diagram of a display module provided by an embodiment of the present application, Figure 2 A bottom structure schematic diagram of a display module provided by an embodiment of the present application, Figure 1 A sectional structure schematic diagram along the sectional line AA', as shown in Figure 1 A sectional structure schematic diagram along the sectional line AA', as shown in Figure 2 As shown in the drawings, the display module 100 includes a display panel 101, a support structure 102 located at the backlight side of the display panel 101, the support structure 102 including a bending area 103 and a non-bending area 104 connected with each other, the support structure 102 further including a first support part 105 and a second support part 106, the first support part 105 being located at the bending area 103, and the second support part 106 being located at the non-bending area 104, the first support part 105 including at least a first etching part 107, the first etching part 107 including at least one first groove 108, and the second support part 106 including at least one second groove 109, along a first direction Z, a height H1 of the first groove 108 being greater than a height H2 of the second groove 109, wherein the first direction Z is a thickness direction of the display panel 101.

[0044] The display panel 101 can be a flexible display panel 101 with bending capability. The support structure 102 is located on the backlight side of the display panel 101, and the support structure 102 includes a bending area 103 and a non-bending area 104 connected to each other. In the example shown in the figure, there is one bending area 103 and two non-bending areas 104. The bending area 103 is connected to the non-bending area 104, and the non-bending area 104 is designed to be axisymmetric according to the bending axis L1 of the bending area 103. During the bending process, the support structure 102 and the display panel 101 are bent synchronously, so the display panel 101 also has a bending area 103 and a non-bending area 104 corresponding to the support structure 102, which ensures the bending effect. The support structure 102 can support the display panel 101, and at the same time, when the display panel 101 is impacted by external force, it can also resist the impact of external force, reducing the risk of damage to the display panel 101. The material of the support structure 102 can include stainless steel, titanium alloy, aluminum alloy, and other metal alloys with good ductility, or high-molecular materials with high modulus, which can also play a certain role in resisting impact. The specific choice can be made according to the actual design requirements, and the present application does not make specific limitations. The support structure 102 includes a first groove 108 in the bending area 103 and a second groove 109 in the non-bending area 104. The first groove 108 is used to release the bending stress during the bending process of the support structure 102, avoid stress concentration, and ensure the bending effect of the display module 100. Multiple second grooves 109 are arranged in the non-bending area 104, and multiple support components similar to reinforcing ribs are formed in the support structure 102. The support components are located between adjacent second grooves 109. When the support components are subjected to external force, the stress can be dispersed to the entire support component, avoiding local stress and damage to the display module 100. At the same time, the design of the second groove 109 in the non-bending area 104 of the support structure 102 can reduce the overall weight of the display module 100 and also play a good role in heat dissipation. In addition, along the first direction Z, the shape of the second groove 109 includes one or a combination of a square, a rectangle, a triangle, a circle, and an ellipse. The specific shape can be selected according to the actual design requirements to ensure the support performance of the support structure 102. In this application, the shape of the second groove 109 is taken as an example of a rectangle. Along the first direction Z, the height H1 of the first groove 108 is greater than the height H2 of the second groove 109. The height H1 of the first groove 108 is set to ensure the bending effect of the bending area 103, and the height H2 of the second groove 109 is set to ensure the impact resistance of the non-bending area 104, improve the use performance of the display module 100 during use, and reduce the risk of damage by external force.

[0045] The embodiment of the present application sets the second groove in the non-bending area of the support structure, matches the first groove formed in the bending area of the support structure, guarantees the bending effect of the support structure, further improves the impact resistance of the display module by the design of the second groove, and guarantees the use effect and display effect of the display module.

[0047] Wherein, the second groove 109 is arranged in the non-bending area 104, the first width of the second groove 109 in the second direction X and the second width of the second groove 109 in the third direction Y are reasonably designed, the bending effect of the display module 100 is guaranteed, and the impact resistance of the module is effectively improved, wherein the bending axis L1 of the support structure 102 can be understood as the bending area 103 in the support structure 102 can be bent away from the light-emitting surface of the display panel 101 or bent towards the light-emitting surface of the display panel 101 with the bending axis L1 as the axis, and the bending area 103 is bent at different angles with the bending axis L1 as the axis during the bending process. The central axis L2 can be understood as the support structure 102 is symmetrically arranged with the central axis L2, that is, the size of the support structure 102 on both sides of the central axis L2 is the same. As shown in Figure 2 As shown in the first width W11 of the first groove 108 is less than the first width W21 of the second groove 109 along the second direction X; or, as shown in Figure 3 The first width W11 of the first groove 108 is equal to the first width W21 of the second groove 109, the layout design of the support structure 102 is reasonably performed, the first groove 108 and the second groove 109 can be formed synchronously by etching, and the preparation process difficulty is simplified. Along the third direction Y, the second width W12 of the first groove 108 and the second width of the second groove 109 can be designed to be the same or be different, Figure 2 and Figure 3The second width W12 of the first groove 108 and the second width of the second groove 109 are the same, which is shown as an example. Figure 4 As shown in the figure, along the second direction X, the first width W11 of the first groove 108 is smaller than the first width W21 of the second groove 109; and along the third direction Y, the second width W12 of the first groove 108 and the second width of the second groove 109 can be designed differently, along the third direction Y, the second width W12 of the first groove 108 is smaller than the second width of the second groove 109, which ensures the release effect of the first groove 108 on the bending stress, and at the same time improves the ability of the support structure 102 to absorb external impact force, thereby improving the impact resistance of the display module 100.

[0048] Optionally, Figure 5 Another bottom view structural schematic diagram of a support structure provided by an embodiment of the present application is provided, Figure 6 Another bottom view structural schematic diagram of a support structure provided by an embodiment of the present application is provided, Figure 5 and Figure 6 As shown in the figure, along the second direction X, the first width W21 of the second groove 109 close to the bending area 103 is greater than the first width W21 of the second groove 109 away from the bending area 103.

[0049] As shown in the figure, Figure 5 along the second direction X, the first width W21 of the second groove 109 close to the bending area 103 is greater than the first width W21 of the second groove 109 away from the bending area 103, so that the support strength of the area close to the bending area 103 is less than the support strength of the area away from the bending area 103, thereby realizing the improvement of the support strength of the edge area of the non-bending area 104 in the second direction X, reducing the risk of damage to the edge area due to external force, and thereby improving the impact resistance of the non-bending area 104. Further, as shown in the figure, Figure 6 the first width W21 of the second groove 109 can be gradually reduced along the second direction X, that is, the first width W21 is gradually designed, so as to gradually improve the support strength of the non-bending area 104 in the second direction X, and further improve the overall impact resistance of the display module 100, thereby ensuring the use performance of the display module 100.

[0050] Optionally, Figure 7 Another bottom view structural schematic diagram of a support structure provided by an embodiment of the present application is provided, Figure 8 Another bottom view structural schematic diagram of a support structure provided by an embodiment of the present application is provided, Figure 9 Another bottom view structural schematic diagram of a support structure provided by an embodiment of the present application is provided, as shown in the figure, Figure 7 , Figure 8 and Figure 9As shown, along the third direction Y, the second width W22 of the second groove 109 close to the middle axis L2 is less than or equal to the second width W22 of the second groove 109 away from the middle axis L2.

[0051] As shown, along the third direction Y, the second width W22 of the second groove 109 close to the middle axis L2 is less than or equal to the second width W22 of the second groove 109 away from the middle axis L2. Figure 5 and Figure 6 As shown, along the third direction Y, the second width W22 of the second groove 109 close to the middle axis L2 is less than or equal to the second width W22 of the second groove 109 away from the middle axis L2. Figure 7 As shown, along the third direction Y, the second width W22 of the second groove 109 close to the middle axis L2 is less than or equal to the second width W22 of the second groove 109 away from the middle axis L2. Figure 8 As shown, along the third direction Y, the second width W22 of the second groove 109 close to the middle axis L2 is less than or equal to the second width W22 of the second groove 109 away from the middle axis L2. Figure 9 As shown, along the third direction Y, the second width W22 of the second groove 109 close to the middle axis L2 is less than or equal to the second width W22 of the second groove 109 away from the middle axis L2.

[0052] As shown, along the third direction Y, the second width W22 of the second groove 109 close to the middle axis L2 is less than or equal to the second width W22 of the second groove 109 away from the middle axis L2. Figure 9 As shown, along the third direction Y, the second width W22 of the second groove 109 close to the middle axis L2 is less than or equal to the second width W22 of the second groove 109 away from the middle axis L2.

[0053] As shown, along the third direction Y, the second width W22 of the second groove 109 close to the middle axis L2 is less than or equal to the second width W22 of the second groove 109 away from the middle axis L2. Figure 9As shown, along the second direction X, the first width W21 of the second groove 109 near the bending area 103 in the non-bending area 104 is greater than the first width W21 of the second groove 109 away from the bending area 103. Along the third direction Y, under the premise that the second width W22 of the second groove 109 near the central axis L2 in the non-bending area 104 is equal to the second width W22 of the second groove 109 away from the bending area 103, along the third direction Y, the first edges 110 of adjacent second grooves 109 are aligned, so that the support components of adjacent second grooves 109 are located on the same straight line, simplifying the manufacturing process of the second grooves 109. Simultaneously, adjusting the first width W21 of the second groove 109 in the second direction X gradually decreases, and simultaneously, along the third direction Y, the second width of the second groove 109 gradually decreases, thereby improving the support strength of the edge region of the non-bending area 104, and thus ensuring the impact resistance of the display module 100.

[0054] Optional, Figure 10 This is a bottom view schematic diagram of another support structure provided in an embodiment of the present invention, as shown below. Figure 9 and Figure 10 As shown, the second groove 109 also includes a second edge 111 parallel to the second direction X, and the second edges 111 of the second groove 109 are aligned with each other at least partially along the second direction X; or the second edges 111 of the second groove 109 are staggered at least partially along the second direction X.

[0055] Furthermore, the second groove 109 also includes a second edge 111 parallel to the second direction X, for example, as shown in the example. Figure 9 As shown, under the premise that the first edges 110 of at least partially adjacent second grooves 109 are aligned along the third direction Y, the second edges 111 of adjacent second grooves 109 are aligned along the second direction X to ensure the support effect and external force release effect of the support structure 102. Or as... Figure 10 As shown, along the second direction X, the first width W21 of a portion of the second groove 109 gradually decreases, and along the third direction Y, the second width W22 of a portion of the second groove 109 gradually decreases. At the same time, along the second direction X, the second edges 111 of adjacent second grooves 109 are staggered. That is, along the third direction Y, the first edges 110 of adjacent second grooves 109 are all located on the same straight line, while along the second direction X, the second edges 111 of adjacent second grooves 109 are located on different straight lines. This makes the adjacent support components in the second direction X discontinuously arranged, which can improve the release effect of the external force when the non-bending area 104 is subjected to external force, ensure the impact resistance of the non-bending area 104, and thus improve the performance of the display module 100. Figure 10In the design of the second groove 109 in the middle, there are some second grooves 109 located on both sides of the middle axis L2, and along the third direction Y, the second width W22 of the second groove 109 close to the middle axis L2 is smaller than the second width W22 of the second groove 109 away from the middle axis L2. For the rational design of each area in the support structure 102, further realize the staggered arrangement of the second edges 111 of adjacent second grooves 109 along the second direction X, and at the same time make the uniformity of the impact resistance of each area of the support structure 102, ensure the support effect of the whole support structure 102, and improve the use performance of the display module 100.

[0056] Optionally, Figure 11 Another bottom structure schematic view of a support structure provided by the embodiment of the present application is shown in Figure 11 As shown, along the second direction X, the first support assembly 112 is arranged between adjacent second grooves 109; along the second direction X, the first width w1 of the first support assembly 112 close to the bending area 103 is greater than the first width w1 of the first support assembly 112 away from the bending area 103.

[0057] Among them, along the second direction X, the first support assembly 112 is arranged between adjacent second grooves 109; along the second direction X, the first width W21 of the second groove 109 gradually decreases, and at the same time, along the second direction X, the first width w1 of the first support assembly 112 close to the bending area 103 is greater than the first width w1 of the first support assembly 112 away from the bending area 103, so that the support strength of the area close to the bending area 103 is smaller than the support strength of the area away from the bending area 103, the support strength of the edge area of the non-bending area 104 is improved, and the impact resistance of the non-bending area 104 is further improved. Further, as shown in Figure 11 The first width w1 of the first support assembly 112 along the second direction X can be adjusted to gradually decrease, so as to gradually improve the support strength of the non-bending area 104 along the second direction X, ensure the overall impact resistance of the display module 100, and further ensure the use performance of the display module 100.

[0058] Optionally, Figure 12 Another bottom structure schematic view of a support structure provided by the embodiment of the present application is shown in Figure 13 Another bottom structure schematic view of a support structure provided by the embodiment of the present application is shown in Figure 12 And Figure 13 As shown, along the third direction Y, the second support assembly 113 is arranged between adjacent second grooves 109; along the third direction Y, the second width w2 of the second support assembly 113 close to the middle axis L2 is greater than the second width w2 of the second support assembly 113 away from the middle axis L2.

[0059] Among them, as shown in Figure 12As shown, the second support assembly 113 is arranged between the adjacent second grooves 109 along the third direction Y; the second width of the second groove 109 gradually decreases along the third direction Y, and the second width w2 of the second support assembly 113 close to the central axis L2 in the non-bending area 104 is smaller than the second width w2 of the second support assembly 113 away from the central axis L2 along the third direction Y, so that the support strength of the area close to the bending area 103 is smaller than the support strength of the area away from the bending area 103, thereby improving the support strength of the edge area of the non-bending area 104 along the third direction Y, and further improving the impact resistance of the non-bending area 104. Further, based on the above embodiment, as shown, Figure 13 As shown, the second width w2 of the second support assembly 113 gradually decreases along the third direction Y, so that the support strength of the non-bending area 104 gradually increases along the third direction Y, thereby ensuring the overall impact resistance of the display module 100, and further ensuring the use performance of the display module 100. Since the first support assembly 112 and the second support assembly 113 are formed by etching the second groove 109 of the support assembly 102, there is a connection relationship between the first support assembly 112 and the second support assembly 113 to ensure the support effect of the support structure 102. The cross-sectional shape of the first support assembly 112 and the second support assembly 113 can be rectangular, trapezoidal, etc. The cross-sectional shape of the first support assembly 112 and the second support assembly 113 is rectangular in the example, and the first support assembly 112 and the second support assembly 113 can provide good support to the display panel 101 to ensure the use effect of the display module 100.

[0060] Optionally, Figure 14 A structural schematic diagram of a display module provided by an embodiment of the present application is shown in the figure, Figure 15 A bottom view structural schematic diagram of another support structure provided by an embodiment of the present application is shown in the figure, Figure 14 And Figure 15 As shown, the first support part 105 further includes a second etching part 114, the second etching part 114 is connected with the first etching part 107 and the second support part 106 respectively, and the second etching part 114 at least includes a third groove 115; the height H3 of the third groove 115 along the first direction Z is smaller than the height H2 of the second groove 109.

[0061] The first support part 105 further comprises a second etching part 114 located between the first etching part 107 and the second support part 106 and connected with the first etching part 107 and the second support part 106 respectively. The second etching part 114 can perform a bending stress transition, reduce the risk of film separation in the second etching part 114 area of the support structure 102 in the bending process, and ensure the bending effect of the support structure 102 as a whole in the bending process.
