The first support film supports the first straight portion, and the second support film supports the second straight portion. The opening is configured to allow the flexible screen body to bend around it. An adhesive fills the opening and connects the first support film and the second support film. Before the support component is attached to the flexible screen body, the adhesive is in a pre-cured state. After the support component is attached to the flexible screen body, the adhesive in the opening is in a cured state.

[0005] The support film has a first surface and a second surface arranged opposite to each other. The first surface is used to attach to the flexible screen.

[0027] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the unfolded structure of an existing display module 1. Figure 2 This is a schematic diagram of the bending structure of display module 1. Display module 1 includes a flexible screen 2, a support film 3, a composite tape 4, and a shim block 5. The flexible screen 2 includes a display section 2a, a bendable section 2b, and a non-display section 2c connected in sequence. The display section 2a, bendable section 2b, and non-display section 2c together form a bending space 2d. The support film 3 includes a first support section 3a disposed on the display section 2a and a second support section 3b disposed on the non-display section 2c. A through hole 3c is formed between the first support section 3a and the second support section 3b at a position corresponding to the bendable section 2b. The support film 3, composite tape 4, and shim block 5 are all disposed within the bending space 2d. One side of the composite tape 4 is connected to the first support section 3a, and the other side is connected to the shim block 5. After bending, the side of the shim block 5 facing away from the composite tape 4 is connected to the second support section 3b.

[0028] In existing technology, after the support film 3 is attached to the flexible screen 2, the through holes 3c of the support film 3 are filled with colloid 6. Because colloid 6 is fluid, it is easy for it to overflow during the filling of the through holes 3c and cover the attachment positions of the composite tape 4 and the shim 5, thereby affecting the attachment effect of the composite tape 4 and the shim 5 and causing product peeling problems in the subsequent display module 1.

[0029] To address the aforementioned problems, embodiments of the present invention provide a display module, and the following description, in conjunction with the accompanying drawings, illustrates various embodiments of the display module.

[0030] Please refer to the following: Figure 3 and Figure 4 In one embodiment of this application, a support component 100 is provided for supporting a flexible screen 10.

[0031] The flexible screen 10 has a first straight portion 11, a bent portion 12, and a second straight portion 13 connected in sequence. The first straight portion 11 is used to display the image, that is, the first straight portion 11 can be the display part of the flexible screen 10. The second straight portion 13 is used as a bonding part, that is, the second straight portion 13 can be the non-display part of the flexible screen 10, used to connect the driving circuit or other devices. The first straight portion 11, the bent portion 12, and the second straight portion 13 together form an accommodating space 14, which is used to accommodate other devices or to provide a buffer area for bending of the flexible screen 10 (e.g., composite tape 40 or shims 50 provided in the accommodating space 14), reducing the risk of the flexible screen 10 being squeezed and damaged.

[0032] The support assembly 100 includes a support film 20 and an adhesive 30. The support film 20 supports the flexible screen 10 and has an opening 21 corresponding to the bending portion 12. The opening 21 divides the support film 20 into a first support film 22 and a second support film 23 spaced apart. The first support film 22 supports the first flat portion 11, providing rigid support to the first flat portion 11, thereby improving the display flatness of the flexible screen 10. The second support film 23 supports the second flat portion 13, providing rigid support to the second flat portion 13, thereby improving the bonding stability of the flexible screen 10. The opening 21 in the support film 20 is configured to allow the flexible screen 10 to bend around it. The opening 21 allows the flexible screen 10 to bend without damaging the support assembly 100. When the flexible screen 10 is bent / unfolded, the support assembly 100 can deform synchronously with the flexible screen 10 without generating additional stress.

[0033] The colloid 30 fills the opening 21 and connects the first support film 22 and the second support film 23. Before the support assembly 100 is attached to the flexible screen 10, the colloid 30 is in a pre-cured state. The pre-cured colloid 30 has a certain degree of viscosity and fluidity, which facilitates the subsequent bonding of the support film 20 to the flexible screen 10. After the support assembly 100 is attached to the flexible screen 10 and the flexible screen 10 is bent, the colloid 30 in the opening 21 is further processed and cured, so that the colloid 30 in the opening 21 is in a cured state, reducing the possibility of the colloid 30 overflowing into other components (such as composite tape 40, shims 50, etc.). The cured colloid 30 can further fix and bond the first support film 22 and the second support film 23, thereby improving the structural strength of the support assembly 100 and thus improving the stability when supporting the flexible screen 10.

[0034] In the aforementioned support component 100, by pre-setting an opening 21 in the support film 20 not attached to the flexible screen 10, and filling the opening 21 with adhesive 30 and pre-curing the adhesive 30, the pre-cured state of the adhesive 30 improves the flexibility and fit of the support film 20 when it is subsequently attached to the flexible screen 10. It also reduces the risk of adhesive 30 overflowing and affecting the attachment of other components (such as the shim block 50) and causing subsequent product delamination. Furthermore, when the flexible screen 10 with the support film 20 attached is bent, the cured state of the adhesive 30 allows the support film 20 to effectively support the flexible screen 10, improving its stability and thus enhancing the product reliability of the display module 200.

[0035] Please refer to the following: Figure 5 and Figure 6In one embodiment, the support film 20 has a first surface 24 and a second surface 25 disposed opposite to each other, the first surface 24 being used to attach to the flexible screen 10 (see Figure 10). Figure 4 This allows the entire support membrane 20 to provide physical support for the flexible screen 10. The opening 21 includes either a through-hole penetrating the first surface 24 and the second surface 25, or a blind hole located on the second surface 25.

[0036] It is understandable that when the opening 21 is a through hole penetrating the first surface 24 and the second surface 25, in the process of preparing the opening 21 on the support film 20, it is possible to directly cut from the first surface 24 to the second surface 25 in the vertical direction, thereby improving the convenience of preparing the opening 21 on the support film 20.

[0037] When the opening 21 is a blind hole located on the second surface 25, the blind hole is equivalent to a groove structure opened on the second surface 25. Without affecting the adhesion between the first surface 24 and the flexible screen 10, the blind hole structure of the second surface 25 can improve the local flexibility and adaptability of the support film 20, and at the same time maintain the structural strength of the entire support film 20 to a certain extent.

[0038] Please see Figure 4 In one embodiment, the width of the opening 21 in the length direction X of the support film 20 is in the range of 0.5mm-1mm, so as to ensure that the position of the opening 21 can correspond to the bending portion 12 of the flexible screen body 10. For example, the width of the opening 21 is 0.5mm, 0.75mm or 1mm, etc., which are not limited here.

[0039] In one embodiment, the depth of the opening 21 is in the range of 50μm-90μm, for example, the depth of the opening 21 is 50μm, 65μm or 90μm, etc., and there is no limitation here.

[0040] In one embodiment, the material of the support membrane 20 includes at least one of polyimide (PI), polyethylene terephthalate (PET), and cyclic olefin polymer (COP), without specific limitation, and can be set as needed.

[0041] In one embodiment, the material of the colloid 30 includes at least one of hot melt adhesive and ultraviolet curable adhesive, without specific limitations, and can be set as needed.

[0042] Please refer to the following: Figure 4 and Figure 5In one embodiment, the support assembly 100 further includes a protective layer 60, which is disposed on one side of the support film 20. The protective layer 60 ensures the cleanliness of the support film 20 and prevents damage to the support film 20 during transportation and handling. It is understood that, relative to the positional relationship between the flexible screen 10 and the support film 20, the protective layer 60 is disposed on the side of the support film 20 facing away from the flexible screen 10, that is, the protective layer 60 is disposed on the second surface 25 of the support film 20.

[0043] In one embodiment, the material of the protective layer 60 includes at least one of polyethylene terephthalate (PET), polyethylene (PE), and polypropylene (PP), and its thickness can be set according to actual needs.

[0044] Please continue reading. Figure 4 and Figure 5 In one embodiment, the support assembly 100 further includes a release layer 70, which is disposed on the side of the support film 20 opposite to the protective layer 60. This ensures the cleanliness and reliable adhesion of the support film 20 before it is adhered to the flexible screen 10. The release layer 70 is configured to be peelable from the support film 20, allowing the support film 20 to adhere to the flexible screen 10, thereby supporting and protecting the flexible screen 10 and reducing the risk of deformation caused by bending.

[0045] In one embodiment, the material of the release layer 70 includes at least one of polyethylene terephthalate (PET), polyethylene (PE), and polypropylene (PP), and its thickness can be set according to actual needs.

[0046] Please continue reading. Figure 4 and Figure 5 In one embodiment, the orthographic projection of the release layer 70 onto the protective layer 60 completely coincides with the orthographic projection of the support film 20 onto the protective layer 60, so that the release layer 70 can cover the entire support film 20, thereby improving the cleanliness and adhesion reliability of the support film 20. Of course, in other embodiments, the orthographic projection of the release layer 70 onto the protective layer 60 may extend beyond the orthographic projection of the support film 20 onto the protective layer 60, while simultaneously covering it.

[0047] It is easy to understand that when attaching the support component 100 to the flexible screen 10, the release layer 70 needs to be peeled off first, and then the support component 100 is attached to the flexible screen 10.

[0048] Please refer to it again. Figure 3 and Figure 4 This application also provides a display module 200, including a flexible screen 10 and the aforementioned support component 100, wherein the support component 100 is connected to the flexible screen 10 and is used to support the flexible screen 10.

[0049] Specifically, the flexible screen 10 is provided with a first straight portion 11, a bent portion 12, and a second straight portion 13 connected in sequence. The first straight portion 11 is used to display the image, that is, the first straight portion 11 can be the display portion of the flexible screen 10. The second straight portion 13 is used as a bonding portion, that is, the second straight portion 13 can be the non-display portion of the flexible screen 10, used to connect the driving circuit or other devices. The first straight portion 11, the bent portion 12, and the second straight portion 13 together form an accommodating space 14, which is used to accommodate other devices or to provide a buffer area for bending of the flexible screen 10 (for example, by setting composite tape 40 and shims 50 in the accommodating space 14) to reduce the risk of the flexible screen 10 being squeezed and damaged.

[0050] The support assembly 100 is located in the accommodating space 14 and attached to the flexible screen body 10. The support assembly 100 is used to support the flexible screen body 10. The support assembly 100 includes a support film 20 and an adhesive 30. The support film 20 supports the flexible screen body 10 and has an opening 21 corresponding to the bent portion 12. The opening 21 divides the support film 20 into a first support film 22 and a second support film 23 spaced apart. The first support film 22 supports the first flat portion 11, providing rigid support to the first flat portion 11, thereby improving the display flatness of the flexible screen body 10. The second support film 23 supports the second flat portion 13, providing rigid support to the second flat portion 13, thereby improving the bonding stability of the flexible screen body 10. The opening 21 in the support membrane 20 allows the flexible screen body 10 to be bent around it, so that the flexible screen body 10 can be bent without damaging the support component 100. When the flexible screen body 10 is bent / unfolded, the support component 100 can deform synchronously with the flexible screen body 10 without generating additional stress.

[0051] The colloid 30 fills the opening 21 and connects the first support film 22 and the second support film 23. Before the support assembly 100 is attached to the flexible screen 10, the colloid 30 is in a pre-cured state. The pre-cured colloid 30 has a certain degree of viscosity and fluidity, which facilitates the subsequent bonding of the support film 20 to the flexible screen 10. After the support assembly 100 is attached to the flexible screen 10 and the flexible screen 10 is bent, the colloid 30 in the opening 21 is further processed and cured, so that the colloid 30 in the opening 21 is in a cured state, reducing the possibility of the colloid 30 overflowing into other components (such as composite tape 40, shims 50, etc.) located in the accommodating space 14. The cured colloid 30 can further fix and bond the first support film 22 and the second support film 23, thereby improving the structural strength of the support assembly 100 and thus improving the stability when supporting the flexible screen 10.

[0052] In the aforementioned display module 200, by pre-setting an opening 21 in the support film 20 not attached to the flexible screen 10, and filling the opening 21 with colloid 30 and pre-curing the colloid 30, the pre-cured state of the colloid 30 improves the flexibility and adhesion of the support film 20 to the flexible screen 10 when the support film 20 is subsequently attached. It also reduces the risk of colloid 30 overflowing and affecting the attachment of other components (such as the shim block 50) and causing subsequent product delamination. Furthermore, when the flexible screen 10 with the support film 20 attached is bent, the cured state of the colloid 30 allows the support film 20 to effectively support the flexible screen 10, improving the stability of the flexible screen 10 and thus enhancing the product reliability of the display module 200.

[0053] Please refer to it again. Figure 5 and Figure 6 In one embodiment, the support film 20 has a first surface 24 and a second surface 25 disposed opposite to each other, the first surface 24 being used to attach to the flexible screen 10 (see Figure 10). Figure 4 This allows the entire support membrane 20 to provide physical support for the flexible screen 10. The opening 21 includes either a through-hole penetrating the first surface 24 and the second surface 25, or a blind hole located on the second surface 25.

[0054] Understandably, in Figure 5 In the process of preparing the opening 21 on the support film 20, when the opening 21 is a through hole that penetrates the first surface 24 and the second surface 25, the opening 21 can be directly cut from the first surface 24 to the second surface 25 in the vertical direction, thereby improving the convenience of preparing the opening 21 on the support film 20.

[0055] exist Figure 6 In the case where the opening 21 is a blind hole located on the second surface 25, the blind hole is equivalent to a groove structure formed on the second surface 25, without affecting the first surface 24 and the flexible screen 10 (see reference). Figure 4 When the two surfaces are bonded together, the blind hole structure of the second surface 25 can improve the local flexibility and adaptability of the support membrane 20, while also maintaining the structural strength of the entire support membrane 20 to a certain extent.

[0056] Please refer to it again. Figure 4 In one embodiment, the width of the opening 21 in the length direction X of the support film 20 is in the range of 0.5mm-1mm, so as to ensure that the position of the opening 21 can correspond to the bending portion 12 of the flexible screen body 10. For example, the width of the opening 21 is 0.5mm, 0.75mm or 1mm, etc., which are not limited here.

[0057] In one embodiment, the depth of the opening 21 is in the range of 50μm-90μm, for example, the depth of the opening 21 is 50μm, 65μm or 90μm, etc., and there is no limitation here.

[0058] In one embodiment, the material of the support membrane 20 includes at least one of polyimide (PI), polyethylene terephthalate (PET), and cyclic olefin polymer (COP), without specific limitation, and can be set as needed.

[0059] In one embodiment, the material of the colloid 30 includes at least one of hot melt adhesive and ultraviolet curable adhesive, without specific limitations, and can be set as needed.

[0060] Please continue reading. Figure 4 In one embodiment, the orthographic projection of the first support film 22 onto the first flat portion 11 covers the first flat portion 11. That is, when viewed from a direction perpendicular to the flexible screen 10, the first support film 22 completely covers the first flat portion 11 (i.e. the part used to display the image), ensuring that the part of the flexible screen 10 used to display the image receives sufficient physical support and maintaining the stability and consistency of the display effect.

[0061] Furthermore, the orthographic projection of the second support film 23 onto the second straight portion 13 covers the second straight portion 13, that is, the second support film 23 also completely covers the second straight portion 13 (i.e. the part in the flexible screen 10 that serves as the bonding portion), so that the second support film 23 not only provides the necessary structural support for the second straight portion 13, but also further protects the electronic components inside the flexible screen 10's accommodating space 14 from damage after bending.

[0062] Please continue reading. Figure 4 In one embodiment, the outer edges of the first support film 22 and the second support film 23 are flush with the outer edge of the flexible screen 10, thereby improving the structural consistency of the display module 200.

[0063] Please see Figure 3 In one embodiment, the display module 200 further includes a protective adhesive layer 80, which is disposed on the side of the bending portion 12 away from the accommodating space 14. The protective adhesive layer 80 is at least partially connected to the bending portion 12. The function of the protective adhesive layer 80 is to form a stress buffer for the bending portion 12 of the flexible screen 10, protect the bending portion 12 during the bending process, reduce the risk of product failure due to cracks in the bending portion 12, and thus extend the service life of the entire display module 200.

[0064] Please continue reading. Figure 3In one embodiment, the protective adhesive layer 80 extends further to the first flat portion 11 and the second flat portion 13, thereby enabling the protective adhesive layer 80 to provide physical protection for the non-bending positions of the flexible screen body 10, further improving the product reliability of the entire display module 200.

[0065] In one embodiment, the material of the protective adhesive layer 80 includes a UV-curable adhesive. In other embodiments, the material of the protective adhesive layer 80 may be specifically set according to requirements, and is not limited herein.

[0066] It is understandable that when the protective adhesive layer 80 extends further to the first flat portion 11 (i.e. the portion used to display the image), in order to meet the requirements of light transmittance, the portion of the protective adhesive layer 80 extending to the first flat portion 11 needs to be made of a light-transmitting material, thereby reducing the risk of the protective adhesive layer 80 blocking the light emitted from the first flat portion 11.

[0067] Please continue reading. Figure 3 In one embodiment, the display module 200 further includes a polarizer 90, which is a core light processing element. The polarizer 90 primarily polarizes the light emitted from the flexible screen 10, thereby improving the display quality of the flexible screen 10 and making the image clearer and brighter. The polarizer 90 is located on the side of the first flat portion 11 opposite to the second flat portion 13, and one end of the polarizer 90 is connected to a protective adhesive layer 80, which helps to fix the position of the polarizer 90 on the first flat portion 11 and reduces the risk of displacement or detachment of the polarizer 90 during bending or use of the flexible screen 10. The orthographic projection of the polarizer 90 on the flexible screen 10 lies within the orthographic projection of the first support film 22 on the flexible screen 10. That is, when viewed in a direction perpendicular to the flexible screen 10, the edge of the polarizer 90 will not exceed the edge of the first support film 22. This ensures that the polarizer 90 can function effectively while reducing potential problems caused by the polarizer 90 exceeding the support range, such as edge lifting.

[0068] In this embodiment, the edge of the polarizer 90 near the protective adhesive layer 80 is recessed relative to the edge of the first straight portion 11 near the bending portion 12, which reduces the risk of cracking or delamination of the polarizer 90 due to stretching / compression during bending. Therefore, it can be understood that in this embodiment, the first straight portion 11 can only emit light to display the image at the position corresponding to the polarizer 90, thereby improving the display quality of the display module 200.

[0069] Please refer to it again. Figure 3 and Figure 4In one embodiment, the display module 200 further includes a composite tape 40 and a shim block 50. The composite tape 40 is disposed on the side of the first support film 22 opposite to the first straight portion 11, and the composite tape 40 has a foam or similar structure to provide cushioning. The shim block 50 is disposed on the side of the composite tape 40 opposite to the first support film 22. After the flexible screen 10 is bent, the shim block 50 is located within the accommodating space 14, and the side of the shim block 50 opposite to the composite tape 40 connects to the side of the second support film 23 opposite to the second straight portion 13. As the main stress-bearing component for bearing bending stress, the shim block 50 elevates the entire display module 200, thereby absorbing the stress generated during bending and reducing the risk of breakage at the bending position of the display module 200 due to excessive stress.

[0070] Please continue reading. Figure 3 and Figure 4 In one embodiment, the orthographic projection of the shim 50 on the flexible screen 10 coincides with the orthographic projection of the composite tape 40 on the flexible screen 10, providing a stable support structure for the flexible screen 10. In other embodiments, the orthographic projections of the shim 50 and the composite tape 40 on the flexible screen 10 may not coincide, and this is not a limitation. For example, in this embodiment, the outer edge of the shim 50 is recessed relative to the outer edge of the composite tape 40.

[0071] Understandably, before the flexible screen 10 is bent, the support film 20 needs to be attached to the flexible screen 10. At this time, the adhesive 30 inside the opening 21 of the support film 20 is in a pre-cured state. After the composite tape 40, the shim block 50 and other components are set on the side of the first support film 22 away from the flexible screen 10, since the adhesive 30 near the end of the first support film 22 is in a pre-cured state, the pre-cured adhesive 30 will not overflow onto the composite tape 40 or the shim block 50. This reduces the risk of the adhesive 30 overflowing and affecting the adhesion of the composite tape 40 or the shim block 50, leading to subsequent product delamination, and improves the structural stability of the entire display module 200.

[0072] Please refer to the following: Figure 7 and Figure 8 This application also provides a method for manufacturing a display module, the method comprising:

[0073] S300: An opening 21 is made in the support membrane 20 to divide the support membrane 20 into a first support membrane 22 and a second support membrane 23 that are spaced apart.

[0074] The opening 21 includes either a through hole penetrating the support membrane 20 or a blind hole located on one side surface of the support membrane 20.

[0075] It is understandable that when the opening 21 is a through hole of the support membrane 20, the support membrane 20 can be directly cut in the vertical direction during the process of preparing the opening 21 on the support membrane 20, thereby improving the convenience of preparing the opening 21 on the support membrane 20.

[0076] When the opening 21 is a blind hole located on one side of the support membrane 20, the blind hole is equivalent to a groove structure opened on the surface of the support membrane 20.

[0077] In one embodiment, the opening 21 can be formed on the support film 20 by means of laser or etching.

[0078] In one embodiment, the width of the opening 21 in the longitudinal direction X of the support membrane 20 ranges from 0.5mm to 1mm, for example, the width of the opening 21 is 0.5mm, 0.75mm or 1mm, etc., and there is no limitation here.

[0079] In one embodiment, the depth of the opening 21 is in the range of 50μm-90μm, for example, the depth of the opening 21 is 50μm, 65μm or 90μm, etc., and there is no limitation here.

[0080] S310: Colloid 30 is formed in opening 21.

[0081] The colloid 30 inside the opening 21 can connect the first support membrane 22 and the second support membrane 23, thereby forming a complete support structure.

[0082] In one embodiment, the materials of the first support film 22 and the second support film 23 include at least one of polyimide (PI), polyethylene terephthalate (PET), and cyclic olefin polymer (COP), without specific limitations, and can be set as needed.

[0083] In one embodiment, the material of the colloid 30 includes at least one of hot melt adhesive and ultraviolet curable adhesive, without specific limitations, and can be set as needed.

[0084] S320: Pre-curing of colloid 30 is performed so that colloid 30 inside opening 21 is in a pre-cured state.

[0085] The pre-cured state of colloid 30 refers to the intermediate state of colloid 30 that is partially cured or not fully cured, and requires subsequent treatment (such as light exposure or heating) to achieve final curing.

[0086] S330: Attach the support film 20 to the flexible screen body 10.

[0087] Understandably, after the support film 20 is attached to the flexible screen 10 to be bent, other components, such as composite tape 40 and shims 50, will be placed on the side of the support film 20 away from the flexible screen 10. At this time, since the adhesive 30 in the support film 20 is in a pre-cured state, it can remain soft or semi-fluid (such as gel) to buffer the stress generated during subsequent bending. At the same time, it can also reduce the situation where the adhesive 30 overflows into other components (such as composite tape 40 and shims 50), reducing the risk that the overflow of adhesive 30 will affect the adhesion effect of other components (such as composite tape 40 and shims 50) and cause delamination of the subsequent product.

[0088] S340: Bend the flexible screen body 10 with the opening 21 of the support film 20 as the bending point.

[0089] Specifically, the flexible screen 10 is bent with opening 21 as the bending point. That is, opening 21 corresponds to the bending position in the flexible screen 10. The opening 21 set in the support film 20 at the bending position of the flexible screen 10 can buffer the stress generated during the bending process of the flexible screen 10, thereby reducing the risk of deformation or cracking of the flexible screen 10 at the bending position. At the same time, the setting of opening 21 also makes the bending and shaping process of the flexible screen 10 at the bending position easier, thereby improving bending efficiency and bending effect.

[0090] S350: Curing the colloid 30 so that the colloid 30 inside the opening 21 is in a cured state.

[0091] In this process, the colloid 30 is cured after the flexible screen 10 is bent to achieve the required hardness and strength, so that the support film 20 can provide stable support for the flexible screen 10.

[0092] Please continue reading. Figure 7 and Figure 8 In one embodiment, step S310 includes: forming an adhesive 30 in the opening 21 by dispensing.

[0093] It is understandable that by dispensing glue into the opening 21, the fluid glue 30 can be naturally filled into the opening 21, and the thickness of the glue 30 can be controlled by controlling the number of dispensings and the amount of glue 30 overflowing during the dispensing process.

[0094] Please refer to the following: Figure 5 , Figure 7 and Figure 8 In one embodiment, a release layer 70 is further provided on one side of the support film 20, and the release layer 70 is configured to be peelable from the support film 20. Before step S330, the method further includes:

[0095] S360: Release layer 70 on the support film 20.

[0096] Specifically, before the support film 20 is adhered to the flexible screen 10, a release layer 70 is provided on the support film 20 to ensure its cleanliness and adhesion reliability. The release layer 70 is configured to be peelable from the support film 20 so that the support film 20 adheres to the flexible screen 10, thereby supporting and protecting the flexible screen 10 and reducing the risk of deformation of the flexible screen 10 due to bending.

[0097] Please refer to it again. Figure 7 and Figure 8 In one embodiment, the flexible screen 10 has a first straight portion 11, a bent portion 12, and a second straight portion 13 connected in sequence. The first straight portion 11 is used to display the image, and the second straight portion 13 is used as a bonding portion. The first straight portion 11, the bent portion 12, and the second straight portion 13 together form an accommodating space 14 in the flexible screen 10. Step S330 includes:

[0098] S331: The first support film 22 is attached to the first straight portion 11, the second support film 23 is attached to the second straight portion 13, and the opening 21 is correspondingly provided in the bending portion 12.

[0099] Specifically, the first support film 22 is attached to the first flat portion 11, which is used to display an image. That is, the first flat portion 11 can be the display portion of the flexible screen 10. In this case, the first support film 22 can provide rigid support for the first flat portion 11, thereby improving the display flatness of the flexible screen 10. The second support film 23 is used to support the second flat portion 13, which is used as a bonding portion. That is, the second flat portion 13 can be the non-display portion of the flexible screen 10, used to connect the driving circuit or other devices. In this case, the second support film 23 can provide rigid support for the second flat portion 13, thereby improving the bonding stability of the flexible screen 10.

[0100] It is understandable that after the flexible screen body 10 is bent with the opening 21 of the support film 20 as the bending point in S340, the first support film 22 and the second support film 23 are placed in the accommodating space 14.

[0101] Please continue reading. Figure 7 and Figure 8 In one embodiment, step S330 is followed by:

[0102] S370: A composite tape 40 and a shim block 50 are attached to the side of the first support membrane 22 opposite to the first straight portion 11.

[0103] Specifically, the composite tape 40 contains foam and other structures that act as a buffer. After bending the flexible screen 10 in S340 using the opening 21 of the support film 20 as the bending point, the composite tape 40 and the shim 50 are also placed within the accommodating space 14. At this time, the side of the shim 50 facing away from the composite tape 40 connects to the side of the second support film 23 facing away from the second straight portion 13. As the main stress-bearing component for bearing bending stress, the shim 50 elevates the entire display module 200, thereby absorbing the stress generated during bending and reducing the risk of breakage at the bending point of the display module 200 due to excessive stress.

[0104] Understandably, the colloid 30 fills the opening 21 and connects the first support film 22 and the second support film 23. Before the support assembly 100 is attached to the flexible screen 10, the colloid 30 is in a pre-cured state. The pre-cured colloid 30 has a certain degree of viscosity and fluidity, which facilitates the subsequent bonding of the support film 20 to the flexible screen 10. After the support assembly 100 is attached to the flexible screen 10 and the flexible screen 10 is bent, the colloid 30 in the opening 21 is further processed and cured, thereby keeping the colloid 30 in the opening 21 in a cured state and reducing the possibility of the colloid 30 overflowing into other components (such as the composite tape 40, the shim block 50, etc.). The cured colloid 30 can further fix and bond the first support film 22 and the second support film 23, thereby improving the structural strength of the support film 20 and thus improving the stability when supporting the flexible screen 10.

[0105] In the above method, by pre-setting an opening 21 in the support film 20 that is not attached to the flexible screen 10, and filling the opening 21 with colloid 30 and pre-curing the colloid 30, the pre-cured state of the colloid 30 can improve the flexibility and adhesion of the support film 20 to the flexible screen 10 when the support film 20 is subsequently attached to the flexible screen 10. It also reduces the risk of colloid 30 overflowing and affecting the attachment of other components (such as the shim block 50) and causing subsequent product delamination. Simultaneously, after the flexible screen 10 with the support film 20 attached is bent, the cured state of the colloid 30 allows the support film 20 to effectively support the flexible screen 10, improving the stability of the flexible screen 10 and thus enhancing the product reliability of the display module 200.

[0106] In one embodiment, step S350 includes: pre-curing the colloid 30 with ultraviolet light.

[0107] Specifically, UV curing can be completed in seconds, thus improving curing efficiency.

[0108] In other embodiments, the colloid 30 may also be cured by thermosetting or other natural curing methods.

[0109] The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
