[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0027] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0028] Figure 1is a schematic structural diagram of a first display module provided by an embodiment of the present invention, Figure 2 is a schematic structural diagram of a second display module provided by an embodiment of the present invention, Figure 3 yes Figure 1 The first cross-sectional diagram along the section line A-A', refer to Figures 1 to 3 As shown, an embodiment of the present invention provides a display module 10, which includes a bendable area 10B and a non-bending area 10A; the display module 10 also includes a display panel 100 and a support structure 200, and the support structure 200 is located on the non-light-emitting side of the display panel 100; the support structure 200 includes a support body 210, a plurality of grooves 220 penetrating at least part of the support body 210 along a first direction X, and a first pressure regulating structure 230 located in the groove 220, at least part of the groove 220 and at least part of the first pressure regulating structure 230 are located in the bendable area 10B; the first pressure regulating structure 230 includes a first state and a second state, the pressure borne by the first pressure regulating structure 230 in the first state is greater than the pressure borne by the first pressure regulating structure 230 in the second state, and the Young's modulus of the first pressure regulating structure 230 in the first state is greater than the Young's modulus of the first pressure regulating structure 230 in the second state.

[0029] Specifically, refer to Figure 1 and Figure 2 As shown, the display module 10 includes a display panel 100 and a support structure 200, the display panel 100 is used to realize the display function of the display module 10, and the support structure 200 is used to provide a supporting force, thereby ensuring the overall structural stability of the display module 10. And the support structure 200 is located on the non-light-emitting side of the display panel 100, that is, the support structure 200 provided will not block or affect the display of the display panel 100, thereby ensuring the overall display effect of the display module 10. Optionally, the display panel 100 includes a plurality of light-emitting elements (not specifically shown in the figure), as well as a driving circuit for driving the light-emitting elements to display light, and signal routing, etc., which are not described in detail in the embodiment of the present invention. Optionally, the display module 10 also includes a backplane assembly located on the support structure 200 away from the display panel 100, a cover plate located on the display panel 100 away from the support structure 200, etc., which are not described in detail in the embodiment of the present invention.

[0030] Furthermore, the display module 10 includes a non-bending area 10A and a bendable area 10B, wherein the non-bending area 10A can be understood as a display area that does not deform, and the bendable area 10B is a display area that can be deformed and bent. Figure 1 and Figure 2 As shown, the display module 10 can be formed at the bending area 10B as shown in FIG. Figure 2 As shown, the display module 10 is bent, so that a foldable design of the display module 10 can be realized. It should be noted that Figure 2 It can be understood as Figure 1 , which is used to illustrate the appearance of the display panel 100 and the supporting structure 200 when the display module 10 is bent in the bending area 10B.

[0031] The support structure 200 includes a support body 210, and the support body 210 is used to achieve the support effect of the support structure 200 on the display module 10 as a whole. The support structure 200 also includes a plurality of grooves 220, and the grooves 220 penetrate at least part of the support body 210 along the thickness direction of the display module 10. At least part of the grooves 220 are located in the bendable area 10B, which can ensure that when the display module 10 is bent in the bending area 10B, stress concentration in the bending area 10B can be avoided, that is, when the display module 10 is bent in the bending area 10B, stress concentration in the bending area 10B can be avoided. Figure 2 As shown, when bending, the stress at the bending area 10B is dispersed by the groove 220; or it can be understood that the groove 220 provided at the bending area 10B of the support structure 200 can prevent the support structures 200 from being squeezed against each other when the display module 10 is bent, thereby ensuring the stability of the structure.

[0032] Furthermore, the support structure 200 further includes a first pressure regulating structure 230, which is disposed in the slot 220. The first pressure regulating structure 230 may include different states, and in different states, the first pressure regulating structure 230 bears different pressures, so that the support structure 200 can have different pressure resistance conditions in the bending area 10B under different stress conditions, thereby ensuring the stability of the overall structure of the display module 10.

[0033] Specifically, the pressure that the first pressure regulating structure 230 can withstand in the first state is greater than the pressure that the first pressure regulating structure 230 can withstand in the second state. In addition, the Young's modulus of the first pressure regulating structure 230 in the first state is greater than the Young's modulus of the first pressure regulating structure 230 in the second state. It can be understood that in the first state, the hardness of the first pressure regulating structure 230 is relatively large, and the pressure it can withstand is relatively large; while in the second state, the hardness of the first pressure regulating structure 230 is relatively small, and the pressure it can withstand is relatively small. Based on the differences in the Young's modulus of the first pressure regulating structure 230 in different states, and the differences in the pressure it can withstand, it can be ensured that the display module 10 can be adjusted accordingly under different stress conditions, thereby ensuring the overall structural stability and bendability of the display module 10.

[0034] For example, if the display module 10 is a touch display module, the first state can be understood as a situation where a finger or a stylus pen slides or clicks in the bending area 10B, and the second state can be understood as a situation where a finger or a stylus pen does not slide or click in the bending area 10B. In the first state, when a finger or a stylus pen clicks or slides in the bending area 10B, the display module 10 is equivalent to being impacted by an external force. In this case, the Young's modulus of the first pressure adjustment structure 230 is relatively large, that is, the hardness of the first pressure adjustment structure 230 is large, and it can withstand a large pressure, thereby ensuring that the display module 10 can withstand a large pressure, thereby avoiding deformation such as depression of the display module 10 in the bending area 10B, that is, ensuring the overall structural stability of the display module 10. In the second state, when the finger or the stylus does not click or slide in the bending area 10B, the display module 10 is equivalent to having no external force impact. In this case, the Young's modulus of the first pressure adjustment structure 230 can be relatively small, that is, the hardness of the first pressure adjustment structure 230 is relatively small, that is, the support structure 200 is relatively soft in the bending area 10B, which can facilitate the display module 10 to bend in the bending area 10B, that is, it is conducive to realizing the bending design of the display module 10.

[0035] In summary, the display module provided by the embodiment of the present invention includes a display panel and a supporting structure, the display panel is used to realize the display function of the display module; the supporting structure includes a supporting body, a groove and a first pressure adjustment structure; wherein the first pressure adjustment structure may include a first state and a second state, and the pressure borne by the first pressure adjustment structure in the first state is greater than the pressure borne by the first pressure adjustment structure in the second state, and the Young's modulus of the first pressure adjustment structure in the first state is greater than the Young's modulus of the first pressure adjustment structure in the second state, which reflects that the first pressure adjustment structure can withstand different pressures in different states, so the display module can ensure the overall structural stability and bendability under different conditions.

[0036] Figure 4 yes Figure 3 The first enlarged schematic diagram of area B in the middle, refer to Figures 1 to 4 As shown, the first pressure regulating structure 230 includes a non-Newtonian fluid 231 and lossy particles 232 doped in the non-Newtonian fluid 231; the loss capacity of the first pressure regulating structure 230 in the first state is greater than the loss capacity of the first pressure regulating structure 230 in the second state.

[0037] Specifically, the first pressure regulating structure 230 includes a non-Newtonian fluid 231 and lossy particles 232, wherein the non-Newtonian fluid 231 refers to a fluid that does not satisfy Newton's experimental law of viscosity, that is, a fluid whose shear stress and shear strain rate are not linearly related. Furthermore, in the first pressure regulating structure 230, lossy particles 232 are doped inside the non-Newtonian fluid 231. Due to the presence of lossy particles 232, when the first pressure regulating structure 230 is subjected to pressure, the loss capacity is improved, that is, the ability to absorb pressure is improved, and it becomes hard, thereby achieving a good support effect; similarly, when the first pressure regulating structure 230 is not subjected to pressure, the loss capacity remains unchanged, and the degree of hardness remains unchanged; the ability of the non-Newtonian fluid 231 and lossy particles 232 to adjust pressure can be understood as the ability to absorb pressure. Therefore, under the action of the non-Newtonian fluid 231 and the lossy particles 232, the first pressure regulating structure 230 can present different Young's moduli under different pressures, that is, when the pressures that the first pressure regulating structure 230 can withstand are different, its Young's modulus is adjusted accordingly. In this way, it can be ensured that the display module 10 can withstand pressures under different stress conditions. The ability to adjust can be adjusted accordingly, thereby ensuring the overall structural stability and bendability of the display module 10.

[0038] Figure 5 yes Figure 3 The second enlarged schematic diagram of area B in the middle, refer to Figures 1 to 3 , Figure 5 As shown, the first pressure adjustment structure 230 includes a first adjustment section 230a and a second adjustment section 230b, the first adjustment section 230a is located on the side of the second adjustment section 230b close to the display panel 10; the doping ratio of the loss particles 232 in the first adjustment section 230a is greater than the doping ratio of the loss particles 232 in the second adjustment section 230b.

[0039] Among them, the first pressure adjustment structure 230 includes a first adjustment section 230a and a second adjustment section 230b, and the doping ratio of the loss particles 233 in the first adjustment section 230a and the doping ratio of the loss particles 233 in the second adjustment section 230b are differentiated, so that the pressure absorption capacity of the first pressure adjustment structure 230 can be differentiated.

[0040] Specifically, due to the location of the external pressure, different areas of the first pressure regulating structure 230 have different pressure tolerances. Therefore, by differentially setting the pressure absorption capacity of the first pressure regulating structure 230, it can be ensured that the first pressure regulating structure 230 can better adjust its ability to withstand pressure under different force conditions, thereby ensuring the overall structural stability and bendability of the display module 10.

[0041] Specifically, refer to Figure 5 As shown, the first adjustment section 230a is located on the side of the second adjustment section 230b close to the display panel 10, and the doping ratio of the loss particles 232 in the first adjustment section 230a is adjusted to be greater than the doping ratio of the loss particles 232 in the second adjustment section 230b. Further, taking the touch pressure as an example, it is applied to the display panel, so in the first pressure adjustment structure 230, the area close to the display panel 100 will be subject to greater pressure, so the doping ratio of the loss particles 232 in the first adjustment section 230a is adjusted to be greater than the doping ratio of the loss particles 232 in the second adjustment section 230b, ensuring that the first pressure adjustment structure 230 has adaptability to withstand pressure under different stress conditions. For example, when the display module 10 is subjected to external force, it can be understood that when the display module 10 is a touch display module, a finger or a stylus slides and clicks on the display panel 100. In this case, the pressure borne by the first adjustment section 230a will be greater than the pressure borne by the second adjustment section 230b. Therefore, the doping ratio of the loss particles 232 in the first adjustment section 230a is adjusted to ensure the overall structural stability and bendability of the display module 10.

[0042] Figure 6 yes Figure 3 The first enlarged schematic diagram of area C in the middle, Figure 7 yes Figure 1 The first enlarged schematic diagram of area D in the middle, refer to Figures 1 to 3 , Figure 6 and Figure 7 As shown, the support structure 200 includes a first A pressure regulating structure 2301 and a first B pressure regulating structure 2302. The first A pressure regulating structure 2301 is located on the side of the first B pressure regulating structure 2302 away from the non-bending area 10A; the doping ratio of the loss particles 232 in the first A pressure regulating structure 2301 is greater than the doping ratio of the loss particles 232 in the first B pressure regulating structure 2302.

[0043] Among them, reference Figure 6 and Figure 7As shown, the support structure 200 includes a first A pressure regulating structure 2301 and a first B pressure regulating structure 2302, wherein the first A pressure regulating structure 2301 is located on the side of the first B pressure regulating structure 2302 away from the non-bending area 10A. And the doping ratio of the loss particles 232 in the first A pressure regulating structure 2301 and the doping ratio of the loss particles 232 in the first B pressure regulating structure 2302 are designed differently, so as to further ensure the stability of the overall structure of the display module 10. Among them, the first A pressure regulating structure 2301 and the first B pressure regulating structure 2302 can be understood as the first pressure regulating structure 230 filled in the groove 220 at different distances from the non-bending area 10A in the support structure 200.

[0044] Specifically, compared with the area close to the non-bending area 10A, the number of slots 220 in the area far from the non-bending area 10B is larger, and the support body 210 is more missing. On the basis of the same bearing pressure, the pressure required to be borne by the first pressure regulating structure 230 is larger, so the first pressure regulating structure 230 in the area far from the non-bending area 10B has a larger pressure bearing capacity. Therefore, in order to ensure that the pressure bearing of the support structure 200 is balanced, the pressure bearing capacity of the first pressure regulating structure 230 in the slots 220 far from the non-bending area 10A can be greater than the pressure bearing capacity of the first pressure regulating structure 230 in the slots 220 close to the non-bending area 10A.

[0045] Specifically, refer to Figure 6 and Figure 7 As shown, the first A pressure regulating structure 2301 is located on the side of the first B pressure regulating structure 2302 away from the non-bending area 10A. The doping ratio of the loss particles 232 in the first A pressure regulating structure 2301 is adjusted to be greater than the doping ratio of the loss particles 232 in the first B pressure regulating structure 2302. This can ensure that the pressure bearing capacity of the first A pressure regulating structure 2301 is greater than the pressure bearing capacity of the first B pressure regulating structure 2302. That is, according to the difference in the setting position of the groove 220, the doping ratio of the loss particles 232 of the first pressure adjusting structure 220 filled in the groove 220 is adaptively adjusted to further ensure the overall structural stability and bendability of the display module 10.

[0046] Figure 8 yes Figure 1 The second cross-sectional diagram along the section line A-A', refer to Figure 1 and Figure 8As shown, the support structure 200 also includes a second pressure adjustment structure 240 located in the groove 220; the second pressure adjustment structure 240 is located on the side of the first pressure adjustment structure 230 close to the display panel 10, and the Young's modulus of the second pressure adjustment structure 240 is greater than the Young's modulus of the first pressure adjustment structure 230.

[0047] Specifically, refer to Figure 8 As shown, the first pressure regulating structure 230 and the second pressure regulating structure 240 can be filled in the groove 220 provided in the support structure 200, and the second pressure regulating structure 240 is located on the side of the first pressure regulating structure 230 close to the display panel 10. That is, the first pressure regulating structure 230 and the second pressure regulating structure 240 filled in the groove 220 have a position setting difference in the first direction X.

[0048] Furthermore, the Young's modulus of the second pressure regulating structure 240 is greater than that of the first pressure regulating structure 230, which can be understood as the hardness of the second pressure regulating structure 240 is greater than the hardness of the first pressure regulating structure 230, and therefore the pressure bearing capacity of the second pressure regulating structure 240 is greater than the pressure bearing capacity of the first pressure regulating structure 230. And the second pressure regulating structure 240 is arranged on the side close to the display panel 100, so that on the one hand, the pressure bearing capacity of the entire support structure 200 can be improved, and on the other hand, the flatness of the support structure 200 at the groove 220 can be ensured, so that the support structure 200 can provide a good flatness setting condition for the display panel 100, thereby ensuring a good display effect.

[0049] Fig. 9 yes Figure 8 The first enlarged schematic diagram of the middle area E, refer to Figure 1 and Fig. 9 As shown, the support structure 200 includes a first groove 221 and a second groove 222, and the first groove 221 is located on a side of the second groove 222 away from the non-bending area 10A; along the first direction X, the thickness of the first pressure regulating structure 230 in the first groove 221 is d11, the thickness of the second pressure regulating structure 240 is d21, the thickness of the first pressure regulating structure 230 in the second groove 222 is d12, and the thickness of the second pressure regulating structure 240 is d22; wherein, d11 / d21<d12 / d22.

[0050] Furthermore, by adjusting the thickness difference between the first pressure regulating structure 230 and the second pressure regulating structure 240 in the groove 220, a differentiated setting of the pressure bearing capacity in the corresponding groove 220 can be achieved. Specifically, the support structure 200 includes a first groove 221 and a second groove 222, wherein the first groove 221 is located on the side of the second groove 222 away from the non-bending area 10A. Compared with the grooves 220 close to the non-bending area 10A, the number of grooves 220 in the area away from the non-bending area 10B is larger, and the support body 210 is more missing. On the basis of the same bearing pressure, the pressure required to be borne by the first pressure regulating structure 230 is larger, so the first pressure regulating structure 230 in the area away from the non-bending area 10B has a larger pressure bearing capacity. Therefore, in order to ensure that the support structure 200 has a balanced bearing capacity for pressure, the pressure-bearing capacity of the first pressure regulating structure 230 and the second pressure regulating structure 240 in the first groove 221 away from the non-bending area 10A can be greater than the pressure-bearing capacity of the first pressure regulating structure 230 and the second pressure regulating structure 240 in the second groove 222 close to the non-bending area 10A.

[0051] Furthermore, the Young's modulus of the second pressure regulating structure 240 is greater than that of the first pressure regulating structure 230, so increasing the thickness ratio of the second pressure regulating structure 240 in the slot 220 can enhance the pressure bearing capacity of the region. Fig. 9 As shown, the thickness of the first pressure regulating structure 230 in the first slot 221 is d11, the thickness of the second pressure regulating structure 240 is d21, the thickness of the first pressure regulating structure 230 in the second slot 222 is d12, and the thickness of the second pressure regulating structure 240 is d22; wherein d11 / d21<d12 / d22, it can be understood that the ratio of the first pressure regulating structure 230 and the second pressure regulating structure 240 in the first slot 221 is smaller than the ratio of the first pressure regulating structure 230 and the second pressure regulating structure 240 in the second slot 222 The ratio of the pressure regulating structure 240, that is, the thickness of the first pressure regulating structure 230 in the first groove 221 accounts for a smaller proportion, and the thickness of the second pressure regulating structure 240 accounts for a larger proportion, while in the second groove 222, the thickness of the first pressure regulating structure 230 accounts for a larger proportion, and the thickness of the second pressure regulating structure 240 accounts for a smaller proportion, thereby realizing adaptive adjustment of the pressure-bearing capacity in the grooves 220 at different positions, thereby ensuring the pressure-bearing balance of different areas of the support structure, and further ensuring the overall structural stability of the display module 10.

[0052] Continue to refer Figure 1 and Figure 8As shown, along the first direction X, the thickness of the first pressure regulating structure 230 is d1, the thickness of the second pressure regulating structure 240 is d2, and the depth of the groove 220 is d3; wherein, 80%≤d1 / d3≤95%; 5%≤d2 / d3≤20%.

[0053] Furthermore, 80%≤d1 / d3≤95%, which can be understood as the ratio between the thickness of the first pressure regulating structure 230 and the depth of the groove 220 is between 80%-95%. At this time, the first pressure regulating structure 230 is more filled in the groove, but it does not completely fill the groove. Since the first pressure regulating structure 230 has a larger Young's modulus under a larger pressure, its "stronger when facing strong" characteristic can ensure that the support structure has a wider pressure bearing range and ensure that the support structure can have a wide range of applicability under different degrees of pressure. In addition, even if lossy particles are provided in the first pressure regulating structure 230, its overall Young's modulus is still smaller than the support body 210, that is, relative to the support body 210, the first pressure regulating structure 230 still has good softness, ensuring that the bending zone 10B has good bendability.

[0054] 5%≤d2 / d3≤20%, which can be understood as the ratio between the thickness of the second pressure regulating structure 240 and the depth of the groove 220 is between 5%-20%. At this time, the second pressure regulating structure 230 is partially filled in the groove, but the filling ratio is smaller than that of the first pressure regulating structure 240. Due to the larger Young's modulus of the second pressure regulating structure 240, the setting of the second pressure regulating structure 240 can improve the pressure bearing energy and flatness performance of the support structure 200. When the second pressure regulating structure 240 has a smaller filling ratio, it ensures that it will not cause significant interference to the bendability of the bending zone, thereby ensuring good bendability of the display module.

[0055] Fig.10 yes Figure 3 The third enlarged schematic diagram of area B in the middle, refer to Figures 1 to 3 , Fig.10 As shown, in the same slot 220 , there is a gap between the first pressure regulating structure 230 located in the slot 220 and the side wall 220 a of the slot 220 .

[0056] Specifically, refer to Fig.10 As shown, there is a gap d between the first pressure regulating structure 230 and the side wall 220a of the groove 220 in the groove 220, that is, there is a non-contact design between the first pressure regulating structure 230 and the side wall 220a of the groove 220. By ensuring that there is a gap d between the side wall 220a and the first pressure regulating structure 230 in the groove 220, it is easy to bend the display module 10 in the bending area 10B, thereby ensuring the overall structural stability of the display module 10.

[0057] Optionally, during the preparation of the support structure 200, after the groove 220 is set, before the first pressure regulating structure 230 is filled, a dispensing or other filling film layer can be set on the surface of the side wall 220a of the groove 220, and then the first pressure regulating structure 230 is prepared. After the first pressure regulating structure 230 is prepared, the film layer filled at the side wall 220a is removed, so as to achieve a non-contact design between the first pressure regulating structure 230 and the side wall 220a of the groove 220. The embodiment of the present invention does not specifically limit the material of the film layer filled at the side wall 220a during preparation, and it is sufficient to ensure that there is a gap d between the first pressure regulating structure 230 and the side wall 220a of the groove 220.

[0058] Fig.11 yes Figure 1 The third cross-sectional diagram along the section line A-A', refer to Figure 1 and Fig.11 As shown, the first pressure regulating structure 230 includes a light shielding structure 250 .

[0059] Specifically, refer to Fig.11 As shown, the first pressure regulating structure 230 includes a shading structure 250, that is, the first pressure regulating structure 230 itself has a shading property and can block light, or it can be understood that the first pressure regulating structure 230 itself is a light-absorbing material and can absorb and block light transmitted to the first pressure regulating structure 230.

[0060] Furthermore, the first pressure regulating structure 230 provided in the groove 220 includes a light shielding structure 250, which can be understood as the non-Newtonian fluid 231 in the first pressure regulating structure 230 being a light shielding structure, that is, the first pressure regulating structure 230 itself can block and shield the light transmitted thereto, thereby ensuring that the display effect of the display panel 100 will not be disturbed, thereby ensuring the overall display effect of the display module 10. Furthermore, when the first pressure regulating structure 230 itself can shield the light, the additional light shielding structure at the groove 220 can also be reduced, thereby reducing the overall process preparation cost of the display module 10.

[0061] Fig.12 yes Figure 1 The fourth cross-sectional diagram along the section line A-A', refer to Figure 1 and Fig.12 As shown, the first pressure regulating structure 230 includes a light-transmitting structure 260 ; the display module 10 also includes a light-shielding layer 270 located on a side of the support structure 200 away from the display panel 100 , and along the first direction X, the light-shielding layer 270 covers a plurality of grooves 220 .

[0062] Specifically, refer to Fig.12 As shown, the first pressure regulating structure 230 includes a light-transmitting structure 260, that is, when the light is transmitted to the first pressure regulating structure 230, the light will continue to be transmitted. In order to prevent the light from being transmitted at the slot 220 and affecting the overall display effect of the display module 10, the display module 1 is provided with a light-shielding layer 270 on the side of the support structure 200 away from the display panel 100. The light-shielding layer 270 has a light-shielding property and can block the light, or it can be understood that the light-shielding layer 270 itself is a light-absorbing material, which can absorb and block the light transmitted to the light-shielding layer 270.

[0063] refer to Fig.12 As shown, along the thickness direction of the display module 10 , the light shielding layer 270 covers a plurality of slots 220 , which can prevent the slots 220 provided on the support structure 200 from affecting the overall display effect of the display module 10 .

[0064] Fig.13 yes Figure 1 The fifth cross-sectional diagram along the section line A-A', refer to Figure 1 and Fig.13 As shown, the slot 220 includes a first opening 223 close to the display panel 100 and a second opening 224 away from the display panel 100 ; the opening area of ​​the first opening 223 is smaller than the opening area of ​​the second opening 224 .

[0065] Among them, reference Fig.13 As shown, the slot 220 includes a first opening 223 and a second opening 224, wherein the first opening 223 is closer to the display panel 100 than the second opening 224. Furthermore, the shape of the slot 220 can be adjusted by adjusting the opening areas of the first opening 223 and the second opening 224.

[0066] Specifically, the slot 220 in the support structure 200 needs to have a good pressure bearing capacity near the display panel 100, so as to ensure the overall structural stability of the display module 10. Therefore, the opening area of ​​the first opening 223 is adjusted to be smaller than the opening area of ​​the second opening 224, or it can be understood that the slot 220 is set to an inverted trapezoid, so that the larger the area of ​​the support body 210 near the display panel 100, the better the pressure bearing capacity of the support structure 200 is ensured.

[0067] Furthermore, when the non-bending areas 10A on both sides of the display module are Figure 2When bending in the shown bending manner, the bottom end of the groove 220, that is, the end away from the display panel 100, is subjected to greater extrusion stress. At this time, the groove 220 has a larger opening area here, which is filled with more first pressure adjustment structures 230 which are relatively softer than the supporting body 210, which can ensure that the display module has good bendability.

[0068] Continue to refer Figures 1 to 13 As shown, along the first direction X, the thickness of the first pressure regulating structure 230 is less than or equal to the depth of the groove 220 , and the first pressure regulating structure 230 is located in the groove 220 .

[0069] Furthermore, along the first direction X, i.e., along the thickness direction of the display module 10, the thickness of the first pressure regulating structure 230 is adjusted to be less than or equal to the depth of the groove 220, i.e., to prevent the first pressure regulating structure 230 from escaping from the groove 220. It can also be understood that there will be no protruding part of the first pressure regulating structure 230 at the support structure 200, thereby ensuring the flatness of the overall structure of the display module 10.
