The display area 110 includes a first surface and a second surface disposed opposite each other in a first direction. The bending area 120 is bendable so that the bonding area 130 is located on the side of the second surface of the display area 110. The support functional layer 200 is disposed on the second surface of the display area 110. The flexible circuit board 400 is electrically connected to the bonding area 130 and is located on the side of the support functional layer 200 away from the display area 110. Chip 300 is disposed on bonding area 130 or on flexible circuit board 400. Printed circuit board 500 is electrically connected to flexible circuit board 400 and is located on the side of support functional layer 200 away from display area 110. Component 600 is disposed on printed circuit board 500. Optical functional layer 700 is disposed on first surface of display area 110. Cover plate 800 is disposed on the side of optical functional layer 700 away from display area 110, and cover plate 800 includes edge cover plate area 810, which is the area around cover plate 800 extending beyond the orthographic projection of flexible display panel 100 onto cover plate 800. Mounting assembly is disposed on the side of edge cover plate area 810 near display area 110 and / or on the side of support functional layer 200 away from display area 110. The mounting assembly is made of elastic and / or flexible material and is used for detachable mounting of display module.

[0051] In some embodiments of the display module disclosed herein, as shown in Figures 1 to 17, mounting components are provided on the side of the edge cover plate area 810 near the display area 110 and / or on the side of the support functional layer 200 away from the display area 110. These mounting components can be used for the detachable installation of the display module, enabling simple and quick multiple disassembly and assembly to meet the needs of high-frequency replacement and rapid disassembly / assembly. Simultaneously, the simple arrangement of the mounting components within the display device allows the display module to form a modular structure, thereby reducing the assembly difficulty to some extent. Furthermore, the simple structure of the mounting components can also reduce the manufacturing cost of the display module to some extent.

[0052] In some embodiments of this disclosure, the flexible display panel 100 may optionally be a flexible OLED display panel. Alternatively, the flexible display panel 100 may also adopt an on-cell design, integrating functional film layers such as the touch layer into the flexible display panel 100 to achieve integrated touch functionality.

[0053] In some embodiments of this disclosure, the supporting functional layer 200 may optionally include a support plate to support the flexible display panel 100, optical functional layer 700, and other structures in the display module, thereby ensuring the structural stability and bending resistance of the display module. Optionally, the supporting functional layer 200 may also include functional film layers such as a back film and a heat dissipation buffer film (SCF), which can be disposed on one side of the second surface of the display area 110.

[0054] In some embodiments of this disclosure, the flexible circuit board 400 is optionally electrically connected to the bonding area 130, and the flexible circuit board 400 is located on the side of the support functional layer 200 away from the display area 110. Optionally, the flexible circuit board 400 may also be stacked with the bonding area 130, and the flexible circuit board 400 may be located on the side of the bonding area 130 away from the support functional layer 200, or it may be located between the bonding area 130 and the support functional layer 200.

[0055] In some embodiments of this disclosure, chip 300 may include a driver integrated circuit (Driver IC) and a timing controller integrated circuit (TCON IC). Chip 300 is disposed on the bonding area 130 or on the flexible circuit board 400, meaning its placement can be determined based on the packaging method of the display module. Optionally, as shown in Figures 1 and 2, the flexible circuit board 400 is electrically connected to the bonding area 130 and the printed circuit board 500 respectively via conductive adhesive 410, etc. The display module can employ a chip-on-film (COF) packaging method, that is, the chip 300 is packaged onto a chip-on-film (COF) film disposed on the flexible circuit board 400 to achieve its driving function. Optionally, as shown in Figures 3 and 4, the display module can adopt a Chip on PNL (COP) packaging method, in which the chip 300 is directly bonded to the bonding area 130 of the flexible display panel 100 using conductive adhesive 410. The bonding area 130 is electrically connected to the flexible circuit board 400 via conductive adhesive 410 or similar means. The flexible circuit board 400 is then electrically connected to the printed circuit board via conductive adhesive 410 or similar means. Optionally, the conductive adhesive 410 can be an anisotropic conductive film (ACF), which can be used for electrical connection between the display panel and the chip 300, etc. The anisotropic conductive film allows current to be conducted in the vertical direction while insulating in the horizontal direction, so as to facilitate a precise thermo-press bonding process. Optionally, depending on design requirements, the chip 300 can be located on the side of the bonding area 130 near the support functional layer 200, on the side of the flexible circuit board 400 near the support functional layer 200, on the side of the bonding area 130 away from the support functional layer 200, or on the side of the flexible circuit board 400 away from the support functional layer 200. In the following embodiments of this disclosure, a display module of this disclosure is exemplarily described using a COP (Chip-on-Plastic) packaging method.

[0056] In some embodiments of this disclosure, as shown in Figures 1 to 17, the printed circuit board 500 is a basic platform carrying the components 600 and interconnect circuits, and can serve as an external driving circuit board in the display module. The components 600 are disposed on the printed circuit board 500, and can be positioned on the side of the printed circuit board 500 closer to the supporting functional layer 200 or on the side of the printed circuit board 500 farther away from the supporting functional layer 200, depending on design requirements.

[0057] In some embodiments of this disclosure, as shown in Figures 1 to 17, an optical functional layer 700 is disposed on a first surface of the display area 110. The optical functional layer 700 may include a polarizing layer 710, which can be used to control the direction of light, allowing only light with a specific polarization direction to pass through, thereby improving display contrast and color saturation. The optical functional layer 700 also includes an optically clear adhesive layer 720 (OCA) for bonding the layers in the display module, ensuring tight bonding between different structural layers and maintaining optical transparency.

[0058] In some embodiments of this disclosure, as shown in Figures 1 to 17, a cover plate 800 is disposed on the side of the optical functional layer 700 away from the display area 110. The cover plate 800 is a protective component located on the outermost layer of the display panel and can be made of reinforced glass or special plastic material, providing mechanical strength, wear resistance, and protection against the influence of the external environment on the internal structural layers of the display module. The cover plate 800 includes an edge cover plate area 810, which is the area around the cover plate 800 extending beyond the orthographic projection of the flexible display panel 100 onto the cover plate 800. The edge cover plate area 810 can reduce the risk of damage to the flexible display panel 100 and other structural layers from external impacts to a certain extent.

[0059] In some embodiments of this disclosure, as shown in Figures 1 to 17, mounting components are provided on the side of the edge cover plate area 810 near the display area 110 and / or on the side of the support functional layer 200 away from the display area 110. This can reduce the assembly difficulty while ensuring the functionality of the display module product, optimize the production process, facilitate large-scale production and flexible deployment of mounting components, and reduce production and maintenance costs. In particular, it can reduce the consumption of manpower and materials when it is necessary to frequently replace the display module. Meanwhile, the mounting components, made of elastic and / or flexible materials, enable the display module to form a modular structure. This allows for easy, repeated, and non-destructive installation and disassembly of the display module, meeting the needs of various temporary setups or entertainment venues requiring frequent relocation. This satisfies the requirements for high-frequency replacement and rapid assembly / disassembly. Furthermore, it improves the mechanical shock resistance and port contact durability of the display module and mounting components during repeated assembly / disassembly, extending the display module's lifespan, reducing maintenance costs and replacement frequency, and optimizing economic benefits. It also enhances the durability of the display module under frequent handling and high-intensity use environments, ensuring stability and safety in high-wear scenarios such as outdoor entertainment venues, and guaranteeing stable operation in various weather conditions.

[0060] In some embodiments of this disclosure, as shown in Figures 1 to 17, the elastic and / or flexible material used in the mounting assembly can be a silicone-based resin, plastic, or other elastic and / or flexible material. This not only gives the mounting assembly a certain degree of elasticity and / or flexibility to improve the ease of disassembly and reassembly of the mounting assembly and its ability to be repeatedly disassembled and reassembled, but also solves the problem of insufficient durability of the display module under high-intensity use conditions. This can improve the durability of the mounting assembly, enabling it to resist harsh weather conditions and improve its weather resistance and service life.

[0061] In some embodiments of this disclosure, the mounting components can be arranged in various combinations, as shown in Figures 5 and 6. Multiple sets of mounting components can be arranged only on the side of the edge cover area 810 near the display area 110; multiple sets of mounting components can be arranged only on the side of the support functional layer 200 away from the display area 110; as shown in Figures 9 and 10, multiple sets of mounting components can also be arranged on the side of the edge cover area 810 near the display area 110 and the side of the support functional layer 200 away from the display area 110, respectively.

[0062] It should be noted that when the mounting components are placed on the side of the support functional layer 200 away from the display area 110, the mounting components need to avoid the flexible circuit board 400, printed circuit board and other structures on the support functional layer 200.

[0063] As an alternative implementation, as shown in Figures 5 to 17, at least one set of mounting components is disposed on the edge cover area 810 corresponding to the bending area 120.

[0064] In some embodiments of this disclosure, as shown in Figures 5 to 17, the flexible display panel 100 causes the bonding area 130 to flip to the side where the second surface of the display area 110 is located by bending the bending area 120. The bonding area 130 and the flexible circuit board 400 electrically connected to the bonding area 130 are located on the side of the support functional layer 200 away from the display area 110. In order to avoid interference between the mounting components and the bending area 120, bonding area 130, flexible circuit board 400 and printed circuit board when the mounting components are placed on the side of the support functional layer 200 away from the display area 110, at least one set of mounting components can be placed on the edge cover area 810 corresponding to the bending area 120. That is, the display module can be installed and fixed in the area corresponding to the bending area 120 by the mounting components. It can also avoid interference between the mounting components and the bending area 120, bonding area 130, flexible circuit board 400 and printed circuit board, thus achieving the purpose of avoiding the bending bonding area 130 domain.

[0065] In some embodiments of this disclosure, as shown in Figures 5 to 17, with at least one set of mounting components disposed on the edge cover area 810 corresponding to the bending area 120, the remaining mounting components may be disposed only on the side of the edge cover area 810 near the display area 110, and the remaining mounting components may be disposed only on the side of the support functional layer 200 away from the display area 110. The remaining mounting components may also be disposed on the side of the edge cover area 810 near the display area 110 and the side of the support functional layer 200 away from the display area 110, respectively. Thus, by adjusting the placement of the mounting components, mounting components can be provided on all four sides of the back of the display module, enabling the display module to be installed and fixed by the mounting components on all four sides of the back, thereby improving the strength and stability of the installation and fixing of the display module.

[0066] As an optional implementation, as shown in Figures 1 to 12, the mounting assembly includes a plate-type body 910, which includes a plate-type fixing end 911 and a plate-type mounting end 912 disposed opposite to each other in a first direction; the plate-type fixing end 911 is disposed on the side of the edge cover plate area 810 near the display area 110 and / or disposed on the side of the support functional layer 200 away from the display area 110, and the plate-type bodies 910 of the multiple mounting assemblies surround each other.

[0067] In some embodiments of this disclosure, as shown in Figures 1 to 12, the mounting assembly includes a plate-type body 910. The plate-type body 910 includes a plate-type fixing end 911 and a plate-type mounting end 912 disposed opposite to each other in a first direction. By setting the plate-type fixing end 911 on the side of the edge cover plate area 810 near the display area 110 and / or on the side of the support functional layer 200 away from the display area 110, the plate-type bodies 910 of multiple mounting assemblies can surround the back of the display module. On the one hand, a relatively sealed structure can be formed on the back of the display module to protect the flexible circuit board 400, printed circuit board 500, chip 300, and components 600 located on the back of the display module, ensuring the waterproof, dustproof, and temperature resistance range of the display module. On the other hand, the display module can be mounted and fixed by the mounting assemblies around the back, improving the strength and stability of the display module mounting and fixing.

[0068] As an optional implementation, as shown in Figures 9 to 11, the support functional layer 200 includes an edge support area 210, which is a region whose edge distance from the support functional layer 200 is less than a first distance D1. When the plate-type fixing end 911 is disposed on the side of the support functional layer 200 away from the display area 110, the plate-type fixing end 911 is located within the edge support area 210.

[0069] In some embodiments of this disclosure, as shown in Figures 9 to 11, the edge support area 210 is the area of ​​the supporting functional layer 200 near its edge. By placing the plate-type fixing end 911 within the edge support area 210, the plate-type fixing end 911 can be located in the edge area of ​​the supporting functional layer 200. Thus, the fixed plate-type body 910 of the plate-type fixing end 911 surrounds the supporting functional layer 200, enclosing the electrical structures such as printed circuit boards on the supporting functional layer 200 within the space formed by the plate-type body 910.

[0070] As an optional implementation, as shown in Figures 1 to 12, the plate-type fixing end 911 is provided with a plate-type adhesive layer 9111; the plate-type adhesive layer 9111 is attached to the side of the edge cover plate area 810 near the display area 110, the height of the plate-type adhesive layer 9111 in the first direction is a first height F1 in the first direction; H1, the total height of the optical functional layer 700, the display area 110 and the support functional layer 200 in the first direction is a second height H2, the first height F1 in the first direction; H1 is greater than or equal to the second height H2; and / or, the plate-type adhesive layer 9111 is attached to the side of the support functional layer 200 away from the display area 110.

[0071] In some embodiments of this disclosure, as shown in Figures 1 to 12, the plate adhesive layer 9111 can be double-sided adhesive, that is, one side of the double-sided adhesive is adhered to the plate fixing end 911, and the other side of the double-sided adhesive is adhered to the edge cover plate area 810 and / or the support functional layer 200, thereby achieving the purpose of fixing the plate body 910 to the edge cover plate area 810 and / or the support functional layer 200 through the plate adhesive layer 9111.

[0072] In some embodiments of this disclosure, as shown in Figures 1 to 12, the plate adhesive layer 9111 can be made of foam double-sided adhesive so that the plate adhesive layer 9111 can have a certain buffering performance, improve its adhesion and fixation reliability and impact resistance, and thus improve the service life of the installation components.

[0073] In some embodiments of this disclosure, as shown in Figures 1 to 12, the height of the plate adhesive layer 9111 in the first direction is a first height F1 (first direction H1), and the total height of the optical functional layer 700, the display area 110, and the support functional layer 200 in the first direction is a second height H2. By making the first height F1 (first direction H1) greater than or equal to the second height H2, when the plate adhesive layer 9111 is attached to the side of the edge cover plate area 810 near the display area 110, the plate adhesive layer 9111 can exceed the optical functional layer 700, the display area 110, and the support functional layer 200 in the first direction. The total height of the display area 110 and the supporting functional layer 200 allows the panel adhesive layer 9111 to be arranged adjacent to or in flexible contact with the optical functional layer 700, the display area 110 and the supporting functional layer 200. This avoids contact between the panel body 910 and the optical functional layer 700, the display area 110 and the supporting functional layer 200, and prevents interference or collision with them. This can improve the protection of the optical functional layer 700, the display area 110 and the supporting functional layer 200 to a certain extent.

[0074] As an optional implementation, as shown in Figures 1 to 12, the bonding width W of the plate adhesive layer 9111 is greater than or equal to 1.5 mm.

[0075] In some embodiments of this disclosure, as shown in Figures 1 to 12, the plate-type body, as an installation component, is bonded and fixed to the side of the edge cover plate area 810 near the display area 110 and / or disposed on the side of the support functional layer 200 away from the display area 110 by a plate adhesive layer 9111. By making the bonding width W of the plate adhesive layer 9111 greater than or equal to 1.5 mm, the bonding area of ​​the plate adhesive layer 9111 can be ensured, and its bonding strength can be ensured, thereby reducing the risk of the plate-type body 910 falling off the edge cover plate area 810 and / or the support functional layer 200 to a certain extent.

[0076] In some embodiments of this disclosure, as shown in Figures 1 to 12, provided that the board adhesive layer 9111 does not interfere with electrical structures such as printed circuit boards on the edge cover plate area 810 and / or the support functional layer 200, the bonding width W of the board adhesive layer 9111 can be adaptively adjusted according to the bonding width available on the edge cover plate area 810 and / or the support functional layer 200, so that the board adhesive layer 9111 has a suitable bonding width W.

[0077] As an optional implementation, as shown in Figures 1 to 12, the maximum distance between the chip 300, flexible circuit board 400, printed circuit board 500, and component 600 and the cover plate 800 in the first direction is the second distance D2, and the distance between the board mounting end 912 and the cover plate 800 in the first direction is the third distance D3, which is greater than the second distance D2.

[0078] In some embodiments of this disclosure, as shown in Figures 1 to 12, in a first direction, the chip 300, flexible circuit board 400, printed circuit board 500, and component 600 can have different stacking arrangements. The maximum distance between the chip 300, flexible circuit board 400, printed circuit board 500, and component 600 and the cover plate 800 is a second distance D2, which reflects the thickness of the display module on the cover plate 800. In the first direction, the distance between the board mounting end 912 and the cover plate 800 is a third distance D3. By making the third distance D3 greater than the second distance D2, it can be ensured that the board mounting end 912 extends beyond the chip 300, flexible circuit board 400, printed circuit board 500, and component 600 in the first direction. This avoids interference between the mounting surface of the display module and the electrical structures such as the chip 300, flexible circuit board 400, printed circuit board 500, and component 600 when the module is mounted and fixed via the board mounting end 912. Optionally, the maximum distance between the chip 300, flexible circuit board 400, printed circuit board 500, and component 600 and the cover plate 800 in the first direction generally does not exceed 4mm. Therefore, the third distance D3 between the board mounting end 912 and the cover plate 800 in the first direction can be made greater than 4mm.

[0079] As an optional implementation, the display module further includes an ink layer 820, which is disposed on the side of the cover plate 800 near the display area 110. The orthographic projection of the ink layer 820 on the cover plate 800 covers the edge cover plate area 810, and the orthographic projection of the ink layer 820 on the cover plate 800 overlaps with the edge area of ​​the orthographic projection of the display area 110 on the cover plate 800. The board adhesive layer 9111 is attached to the side of the ink layer 820 away from the cover plate 800.

[0080] In some embodiments of this disclosure, as shown in Figures 1 to 7, the display module further includes an ink layer 820. The ink layer 820 is disposed on the side of the cover plate 800 near the display area 110. By making the orthographic projection of the ink layer 820 on the cover plate 800 cover the edge cover plate area 810, and by making the orthographic projection of the ink layer 820 on the cover plate 800 overlap with the edge area of ​​the orthographic projection of the display area 110 on the cover plate 800, the ink layer 820 can shield the traces of the flexible display panel 100 and prevent light leakage from the edge of the display module. At the same time, the board adhesive layer 9111 is attached to the side of the ink layer 820 away from the cover plate 800. The ink layer 820 can also shield the board adhesive layer 9111 and the board body 910. Therefore, the ink layer 820 can ensure the aesthetics of the display module.

[0081] In some embodiments of this disclosure, the ink layer 820 may optionally increase the abrasion resistance of the edge cover area 810 to facilitate the placement of mounting components in the edge cover area 810.

[0082] As an optional implementation, as shown in Figures 5 to 12, the plate mounting end 912 is provided with a mounting buckle 9121, and the orthographic projection of the mounting buckle 9121 on the cover plate 800 does not exceed the cover plate 800.

[0083] In some embodiments of this disclosure, as shown in Figures 5 to 12, the plate mounting end 912 is provided with a mounting clip 9121, thereby enabling the detachable installation of the display module. By ensuring that the orthographic projection of the mounting clip 9121 on the cover plate 800 does not exceed the cover plate 800, interference between the mounting clip 9121 and adjacent display modules can be avoided during the installation of the display module.

[0084] In some embodiments of this disclosure, as shown in Figures 5 to 8, when the plate fixing end 911 of the plate body 910 is located on the side of the edge cover area 810 near the display area 110, the orthographic projection of the plate mounting end 912 on the cover plate 800 is relatively close to the edge of the cover plate 800. Therefore, the mounting buckle 9121 provided on the plate mounting end 912 can be set in a single-sided hook manner to avoid the orthographic projection of the mounting buckle 9121 on the cover plate 800 exceeding the cover plate 800.

[0085] In some embodiments of this disclosure, as shown in Figures 9 to 12, the plate-type fixing end 911 of the plate-type main body 910 is located on the side of the supporting functional layer 200 away from the display area 110. The orthographic projection of the plate-type mounting end 912 on the cover plate 800 is at a certain distance from the edge of the cover plate 800. The distance between the orthographic projection of the plate-type mounting end 912 on the cover plate 800 and the edge of the cover plate 800 is at least greater than the width of the edge cover plate area 810. Therefore, the mounting buckle 9121 provided on the plate-type mounting end 912 can adopt a double-sided hook setting to improve the installation fixing strength and stability of the mounting buckle 9121. Optionally, when the plate-type fixing end 911 of the plate-type main body 910 is located on the side of the supporting functional layer 200 away from the display area 110, the mounting buckle 9121 provided on the plate-type mounting end 912 can also adopt a single-sided hook setting.

[0086] As an optional implementation, as shown in Figures 5 to 12, the height of the mounting buckle 9121 in the first direction is the third height H3, and the height of the plate body 910 in the first direction is the fourth height H4. The third height H3 is greater than one-tenth of the fourth height H4.

[0087] In some embodiments of this disclosure, as shown in Figures 5 to 12, the height of the mounting buckle 9121 in the first direction is the third height H3, and the height of the plate body 910 in the first direction is the fourth height H4. By making the third height H3 greater than one-tenth of the fourth height H4, the mounting buckle 9121 can have sufficient strength to ensure that the mounting buckle 9121 has sufficient fixing strength.

[0088] As an optional implementation, as shown in Figures 5 to 12, the display module further includes a side seal 920. The side seal 920 is at least disposed on the side end face and edge cover plate area 810 of the optical functional layer 700, the display area 110 and the support functional layer 200 that are not surrounded by the plate body 910. The orthographic projection of the side seal 920 on the cover plate 800 does not exceed the cover plate 800. The side end face is a surface of the optical functional layer 700, the display area 110 and the support functional layer 200 that are parallel to the first direction.

[0089] In some embodiments of this disclosure, as shown in Figures 5 to 12, by providing side seals 920 at least on the side end faces and edge cover areas 810 of the optical functional layer 700, display area 110, and support functional layer 200 not enclosed by the plate-type main body 910, the side seals 920 can improve the sealing performance of the display module, preventing corrosion from moisture and dust, thereby improving the weather resistance of the display module and enabling its use in outdoor environments, thus enhancing its safety and lifespan in outdoor settings. Simultaneously, the orthographic projection of the side seals 920 onto the cover plate 800 does not extend beyond the cover plate 800, preventing interference between the side seals 920 and adjacent display modules during installation.

[0090] In some embodiments of this disclosure, as shown in Figures 5 to 12, the height of the side seal 920 in the first direction is at least greater than the support functional layer 200. The height of the side seal 920 in the first direction can also exceed the maximum distance between the flexible circuit board 400, the printed circuit board 500, and the components 600 and the cover plate 800 in the first direction. That is, the height of the side seal 920 in the first direction exceeds the second distance D2, so that the side area of ​​the display module can be completely sealed by the side seal 920, thereby improving the sealing performance of the display module.

[0091] In some embodiments of this disclosure, as shown in Figures 5 to 12, the side seal 920 can be formed on the side end face and edge cover area 810 of the optical functional layer 700, the display area 110 and the support functional layer 200 that are not surrounded by the plate body 910 by using silicone filling, so as to improve the sealing performance of the display module after assembly.

[0092] As an alternative implementation, as shown in Figures 5 to 12, the side seal 920 is also provided in the area where the plate-type fixed end 911 connects with the edge cover area 810 and / or the support functional layer 200.

[0093] In some embodiments of this disclosure, as shown in Figures 5 to 12, by providing the side seal 920 in the area where the plate fixing end 911 connects to the edge cover area 810 and / or the support functional layer 200, the sealing performance of the area where the plate fixing end 911 connects to the edge cover area 810 and / or the support functional layer 200 can be ensured, thereby further improving the sealing performance of the assembled display module.

[0094] With the continuous evolution of OLED technology, especially flexible OLED technology, display products can adapt to more diverse application scenarios, such as achieving curved, foldable, and even rollable designs. As the demand for larger-size displays grows and non-planar application environments expand, the need for display modules to be used in non-planar display applications with curved surfaces is gradually increasing. However, when display modules are installed on non-planar mounting surfaces, they are prone to deformation and wrinkles.

[0095] To address the problem of deformation and wrinkling defects that easily occur when display modules are installed on non-planar mounting surfaces, a display module according to some embodiments of this disclosure, as shown in Figures 13 to 17, includes a mounting component in the display module comprising a suction cup body 930. The suction cup body 930 includes a suction cup fixing end 931 and a suction cup adsorption end 932 disposed opposite to each other in a first direction. The suction cup fixing ends 931 of multiple sets of mounting components are arranged in an array on the side of the edge cover plate area 810 near the display area 110 and / or arranged in an array on the side of the support functional layer 200 away from the display area 110.

[0096] In some embodiments of this disclosure, as shown in Figures 13 to 17, the mounting assembly includes a suction cup body 930. The suction cup body 930 includes a suction cup fixing end 931 and a suction cup adsorption end 932 disposed opposite to each other in a first direction. Multiple sets of suction cup fixing ends 931 of the mounting assembly are arranged in an array on the side of the edge cover plate area 810 near the display area 110 and / or arranged in an array on the side of the support functional layer 200 away from the display area 110. Correspondingly, an array of suction cup adsorption ends 932 is formed on the display module. The array of suction cup adsorption ends 932 mimics the structure of a remora's suction cup. Simultaneously, by adjusting the suction cup body 930 in the first direction… The height of the suction cups 932 can be adjusted to shape the overall suction surface of the display module, allowing it to be fixed to non-planar mounting surfaces. This satisfies non-planar mounting requirements while preventing deformation and wrinkles in the display module, significantly simplifying the installation process. It effectively prevents problems such as wrinkles, film separation, and insufficient rigidity caused by improper installation, ensuring good display functionality and enhancing the overall stability and durability of the display module. This improves the functional value of the display module and strengthens its unique competitive advantage and attractiveness in the market. Furthermore, the suction fixation method of the suction cups 932 is simple to install, allowing for frequent assembly and disassembly, meeting the needs of high-frequency replacement and rapid disassembly of the display module. In addition, the assembly method of the suction cup body 930 on the edge cover area 810 and / or supporting functional layer 200 is simple, and the manufacturing cost of the suction cup body 930 is correspondingly low, effectively reducing the assembly and manufacturing costs of the display module. In some embodiments of this disclosure, a suction cup adsorption method is used to fix the device, which can meet the needs of multi-scene coverage and repeated disassembly and assembly, effectively expanding the installation scenarios of the display module and greatly increasing the added value of OLED products, such as opening up the field of OLED decoration.

[0097] In some embodiments of this disclosure, the suction cup adsorption method can also meet the lightweight requirements of the display module, which can satisfy application scenarios such as vehicle displays that have corresponding requirements for weight reduction.

[0098] In some embodiments of this disclosure, the suction cup bodies 930 are arranged in an array with suction cup fixing ends 931 on the side of the edge cover plate area 810 near the display area 110 and / or arranged in an array on the side of the support functional layer 200 away from the display area 110, forming a certain heat dissipation gap between the suction cup bodies 930, which can improve the heat dissipation performance of the display module and ensure the stability and reliability of the display module during long-term operation.

[0099] In some embodiments of this disclosure, the suction cup body 930 may be made of silicone material, thereby giving the suction cup body 930 good adhesion and durability.

[0100] As an optional implementation, the supporting functional layer 200 includes an edge supporting area 210 and an inner supporting area 220. The edge supporting area 210 is the region whose distance from the edge of the supporting functional layer 200 is less than a first distance D1, and the inner supporting area 220 is the region whose distance from the edge of the supporting functional layer 200 is greater than the first distance D1. When the suction cup fixing end 931 is disposed on the side of the supporting functional layer 200 away from the display area 110, the suction cup fixing end 931 is disposed in the edge supporting area 210 and / or the inner supporting area 220, and the orthographic projection of the suction cup fixing end 931 on the functional supporting layer does not coincide with the orthographic projection of the chip 300, the flexible circuit board 400, the printed circuit board 500, and the component 600 on the functional supporting layer.

[0101] In some embodiments of this disclosure, the suction cup bodies 930 can be positioned in various combinations within the display module according to design requirements. For example, as shown in Figures 13 and 14, multiple suction cup bodies 930 can be arranged in an array on the side of the edge cover area 810 near the display area 110. Alternatively, multiple suction cup bodies 930 can be arranged in an array on the side of the support functional layer 200 away from the display area 110. As shown in Figures 15 and 16, multiple suction cup bodies 930 can be arranged in an array on the side of the edge cover area 810 near the display area 110, and simultaneously, multiple suction cup bodies 930 can be arranged in an array on the side of the support functional layer 200 away from the display area 110. Furthermore, as shown in Figures 15 and 16, when multiple suction cup bodies 930 are arranged in an array on the side of the support functional layer 200 away from the display area 110, the suction cup bodies 930 can also be distributed in the edge support area 210 and / or the internal support area 220. In other words, while ensuring that the orthographic projection of the suction cup fixing end 931 on the functional support layer does not coincide with the orthographic projections of the chip 300, flexible circuit board 400, printed circuit board 500, and component 600 on the functional support layer, thus ensuring that the suction cup body 930 does not interfere with the chip 300, flexible circuit board 400, printed circuit board 500, and component 600, the position of the suction cup body 930 in the display module can be adaptively adjusted according to design needs, and the suction cup body 930 can be distributed as evenly as possible on the back of the display module to provide a more balanced force to the display module.

[0102] In some embodiments of this disclosure, the adsorption area of ​​the suction cup adsorption end 932 at the corresponding position can be adjusted according to the different positions of the suction cup body 930 in the display module. That is, the adsorption area of ​​the suction cup adsorption end 932 is designed differently to adjust the force distribution generated by the arrayed suction cup bodies 930, thereby improving the installation and fixing effect of the display module.

[0103] As an optional implementation, the height of the suction cup body 930 in the first direction is the fifth height H5, and the deformation of the suction cup body 930 in the first direction is less than two-thirds of the fifth height H5; the maximum distance between the chip 300, flexible circuit board 400, printed circuit board 500 and component 600 and the cover plate 800 in the first direction is the second distance D2, and the second distance D2 is less than one-third of the fifth height H5.

[0104] In some embodiments of this disclosure, as shown in Figures 13 to 17, the suction cup body 930 can be deformed in the first direction to allow the suction cup adsorption end 932 to adhere to the mounting surface for vacuum adsorption and fixation. The height of the suction cup body 930 in the first direction is a fifth height H5. By making the deformation amount of the suction cup body 930 in the first direction less than two-thirds of the fifth height H5, the adsorption and fixation effect of the suction cup bodies 930 arranged in an array of deformation amounts in the first direction can be improved. Meanwhile, the maximum distance between the chip 300, flexible circuit board 400, printed circuit board 500, and component 600 and the cover plate 800 in the first direction is the second distance D2. By making the second distance D2 less than one-third of the fifth height H5, that is, by making the suction cup body 930 extend beyond the chip 300, flexible circuit board 400, printed circuit board 500, and component 600 in the first direction, and the extended part is at least two-thirds of the fifth height H5, that is, the extended part exceeds the deformation of the suction cup body 930 in the first direction, thereby avoiding interference between the suction cup body 930 and the electrical structures such as the chip 300, flexible circuit board 400, printed circuit board 500, and component 600 after adsorption, fixation, and deformation.

[0105] In some embodiments of this disclosure, as shown in Figures 13 to 17, the overall shape of the display module can be a curved or other irregular structure. Simultaneously, the mounting surface of the display module can be curved or flat, resulting in different distances between different areas of the back of the display module and the mounting surface. Therefore, the fifth height H5 of the suction cup body 930 can be adaptively adjusted according to the distance between the back of the display module and the mounting surface, matching the fifth height H5 of the suction cup body 930 with the distance between the back of the display module and the mounting surface. This ensures that the height of the suction cup body 930 after adsorption and deformation matches the distance between the back of the display module and the mounting surface, and avoids interference between the electrical structures such as the chip 300, flexible circuit board 400, printed circuit board 500, and components 600 and the mounting surface. As an optional implementation, the suction cup fixing end 931 is provided with a suction cup adhesive layer 9311, which adheres to the side of the edge cover area 810 near the display area 110 and / or adheres to the side of the support functional layer 200 away from the display area 110.

[0106] In some embodiments of this disclosure, as shown in Figures 12 to 17, the suction cup fixing end 931 may be provided with a suction cup adhesive layer 9311, so that the suction cup body 930 can be attached to the side of the edge cover plate area 810 near the display area 110 and / or attached to the side of the support function layer 200 away from the display area 110 through the suction cup adhesive layer 9311.

[0107] In some embodiments of this disclosure, the suction cup adhesive layer 9311 may optionally be double-sided tape, i.e., one side of the double-sided tape is adhered to the suction cup fixing end 931, and the other side of the double-sided tape is adhered to the edge cover plate area 810 and / or the support functional layer 200, thereby achieving the purpose of fixing the suction cup body 930 to the edge cover plate area 810 and / or the support functional layer 200 through the suction cup adhesive layer 9311.

[0108] In some embodiments of this disclosure, the suction cup adhesive layer 9311 may optionally be made of foam double-sided adhesive, so that the suction cup adhesive layer 9311 can have a certain buffering performance, improve its adhesion and fixation reliability and impact resistance, and thus improve the service life of the installation components.

[0109] As an optional implementation, the adsorption area of ​​the suction cup adsorption end 932 is larger than the adhesion area of ​​the suction cup fixing end 931.

[0110] In some embodiments of this disclosure, as shown in Figures 13 to 17, the suction cup fixing end 931 is disposed on the back of the display module and is greatly affected by the structural dimensions of the back of the display module. However, the adsorption area of ​​the suction cup adsorption end 932 is not affected by the size of the display module. Therefore, the adsorption area of ​​the suction cup adsorption end 932 can be increased by making it larger than the contact area of ​​the suction cup fixing end 931, thereby ensuring the adsorption and fixing effect of the suction cup adsorption end 932.

[0111] As an optional implementation, the suction cup adsorption end 932 is funnel-shaped, and the suction cup body 930 is provided with at least one vent hole.

[0112] In some embodiments of this disclosure, as shown in Figures 13 to 17, by making the suction cup adsorption end 932 into a funnel shape, the adsorption area of ​​the suction cup body 930 at the adsorption end 932 is larger than the contact area of ​​the suction cup fixing end 931. Simultaneously, at least one vent hole is provided on the suction cup body 930. When the suction cup body 930 deforms and adsorbs onto the mounting surface, the vent hole can be sealed, ensuring the adsorption and fixing effect of the suction cup body 930. During assembly and disassembly, the vent hole can be kept open, allowing the suction cup adsorption end 932 to be easily removed from the mounting surface.
