For example, a process, method, system, product or device comprising a series of steps or units is not limited to the steps or units listed, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0018] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0019] Before introducing the solution of this application, Figure 1 Introduce the basic structure of display module 1:

[0020] The display module 1 includes a display panel 101, a composite film layer 201, a bonding device 301, a first colloid 401, a support film 501 and a glue layer 601. The composite film layer 201 is arranged on the non-display surface 1011 side of the display panel 101. The bonding device 301 is arranged on the display surface 1012 side of the display panel 101, with one end bonded to the display panel 101 and the other end protruding from the display panel 101 and extending outward. The first colloid 401 adheres the bonding device 301 and the side of the display panel 101 facing the composite film layer 201. The support film 501 is arranged between the display panel 101 and the composite film layer 201, and the glue layer 601 is arranged between the display panel 101 and the support film 501 to adhere the display panel 101 and the support film 501.

[0021] In the related art, cracks 6011 are easily formed in the adhesive layer 601 between the display panel 101 and the composite film layer 201 under the action of external force, and the side of the composite film layer 201 is usually retracted relative to the side of the display panel 101. The first colloid 401 can only adhere to the bonding device 301 and the side of the display panel 101 facing the composite film layer 201, thereby causing the side of the display panel 101 between two adjacent bonding devices 301 to be exposed. When cracks 6011 appear in the adhesive layer 601 between the display panel 101 and the composite film layer 201, water vapor can easily enter through the cracks 6011 and gather at the position of the bonding device 301, causing the bonding device 301 to short-circuit and fail, resulting in poor reliability of the display module 1.

[0022] To avoid the shortcomings of the prior art, please also refer to Figure 2 , Figure 3 and Figure 4 In one embodiment of the present application, a display module 100 is provided. The display module 100 includes a display panel 10, a composite film layer 20 and a first colloid 30. The composite film layer 20 is located on the side of the display panel 10 away from its display surface 11. The composite film layer 20 supports the display panel 10 and can also provide other functional effects for the display panel 10. The first colloid 30 is used to bond the display panel 10 and the composite film layer 20 to improve the overall structural stability of the display module 100.

[0023] Specifically, the composite film layer 20 is disposed on the non-display surface 12 side of the display panel 10, and the first end 21 of the composite film layer 20 extends outwardly by a first predetermined distance L1 relative to the first end 13 of the display panel to form a first extension portion 22 protruding from the first end 13 of the display panel 10. That is, the first extension portion 22 protrudes from the first end 13 of the display panel 10, and during the preparation and assembly process of the display module 100, the first extension portion 22 can protect the edge of the display panel 10 and reduce the risk of the first end 13 of the display panel 10 being impacted by external force.

[0024] The first colloid 30 is disposed on the side of the first extension portion 22 facing the display panel 10, and adheres the first extension portion 22 and the display panel 10. When the first extension portion 22 protrudes from the first end 13 of the display panel 10, the first colloid 30 adheres the first extension portion 22 in the composite film layer 20 and the display panel 10, thereby increasing the contact area between the first colloid 30 and the composite film layer 20, so that the first colloid 30 can cover the side of the display panel 10, reducing the risk of water vapor entering the display module 100 from the side of the display panel 10 and causing short circuit failure of the device in the display module 100.

[0025] In the above display module 100, the first end 21 of the composite film layer 20 is provided with a protruding first extension portion 22 relative to the first end 13 of the display panel 10, so that the first colloid 30 adheres to the first extension portion 22 and the display panel 10, which can increase the contact area between the first colloid 30 and the composite film layer 20 in the display module 100, thereby reducing the risk of external water vapor entering the cracks and causing short circuit failure of the device in the display module 100 when the glue layer 91 in the display module 100 is cracked due to external force. At the same time, increasing the contact area between the first colloid 30 and the composite film layer 20 can also further enhance the overall structural stability of the display module 100, reduce the risk of the display panel 10 being hit by external force, and improve the overall product reliability of the display module 100.

[0026] Please continue reading Figure 2 , Figure 3 and Figure 4 In one embodiment, the display module 100 further includes a cover plate 60, which is disposed on one side of the display surface 11 of the display panel 10, and the orthographic projection of the display panel 10 on the cover plate 60 is located within the cover plate 60. Specifically, the cover plate 60 can provide physical protection for the display panel 10 to prevent the display surface 11 of the display panel 10 from being scratched.

[0027] In one embodiment, the composite film layer 20 is specifically a composite adhesive tape.

[0028] Please also read Figure 4 and Figure 5 In one embodiment, the composite film layer 20 includes an adhesive layer 23, a buffer layer 24 and a conductive layer 25 which are stacked in sequence. The adhesive layer 23 is attached to the display panel 10, and the conductive layer 25 is used for grounding.

[0029] Specifically, the adhesive layer 23 is used to firmly adhere the composite film layer 20 to the display panel 10. The buffer layer 24 is located on the adhesive layer 23, and is used to provide physical buffering for the display panel 10 and absorb external impact force, thereby protecting the display panel 10 from direct damage, wherein the material of the buffer layer 24 includes foam. The conductive layer 25 is located on the buffer layer 24 and is used for static electricity output, and can effectively guide static electricity or electromagnetic interference to the ground, protecting the display panel 10 from electrostatic discharge (ESD) or electromagnetic interference (EMI), wherein the material of the conductive layer 25 includes copper foil.

[0030] Please continue reading Figure 4 and Figure 5 In one embodiment, the composite film layer 20 further includes a support layer 26, and the support layer 26 is disposed between the buffer layer 24 and the conductive layer 25. The support layer 26 is used to further improve the rigidity of the composite film layer 20, thereby increasing the strength of the composite film layer 20 when supporting the display panel 10. The material of the support layer 26 includes polyimide.

[0031] Please also read Figure 3 and Figure 4 In one embodiment, the first predetermined distance L1 ranges from 0.1 mm to 0.2 mm to ensure that the first extension portion 22 can effectively adhere to the first colloid 30 while protruding from the first end 13 of the display panel 10. For example, the first predetermined distance L1 is 0.1 mm, 0.15 mm or 0.2 mm.

[0032] In one embodiment, the material of the first colloid 30 includes any one of OCA (Optically Clear Adhesive) and UV (Ultraviolet) optical adhesive, which is not limited herein.

[0033] Please continue reading Figure 3 and Figure 4 In one embodiment, the display panel 10 further includes a bonding device 40, which is disposed on one side of the display surface 11 of the display panel 10, one end of the bonding device 40 is bonded to the display panel 10, and the other end of the bonding device 40 protrudes out of the display panel 10 and extends outward and is spaced from the first extension portion 22, wherein the first colloid 30 adheres the bonding device 40 and the first extension portion 22. Specifically, the bonding device 40 and the first extension portion 22 are adhered by the first colloid 30, so that the stability of the bonding device 40 when bonded to the display panel 10 can be enhanced, thereby reducing the risk of the bonding device 40 loosening or falling off due to external impact or vibration of the display module 100. At the same time, the first colloid 30 can also form a seal between the bonding device 40 and the first extension portion 22, which can improve the waterproof and dustproof ability of the display module 100, thereby reducing the risk of external water vapor or other impurities entering the display panel 10 from the sealed position of the first colloid 30 and causing the bonding device 40 to short-circuit and fail.

[0034] Please continue reading Figure 3 and Figure 4 In one embodiment, the bonding device 40 includes a chip on film (COF). In this embodiment, one end of the chip on film is bonded to the display surface 11 of the display panel 10, while the other end protrudes out of the display panel 10 and extends outward, so that the chip on film can be more conveniently connected to other components (such as a motherboard), providing flexibility for the subsequent assembly of the chip on film.

[0035] The first colloid 30 adheres the COF and the first extension portion 22 . While fixing the COF position, the first colloid 30 can seal the gap between the display panel 10 and the COF, preventing moisture from entering between the display panel 10 and the COF, thereby protecting the electrical components on the COF.

[0036] In other embodiments, the bonding device 40 further includes a flexible circuit board, a driving circuit, or various sensors.

[0037] Please also read Figure 3 and Figure 6 In one embodiment, the first colloid 30 further extends from the first extension portion 22 through the end surface of the first end 13 of the display panel 10 to the display surface 11 of the display panel 10. The orthographic projection of the first colloid 30 extending to the display surface 11 on the display panel 10 does not overlap with the orthographic projection of the bonding device 40 on the display panel 10.

[0038] Specifically, the first colloid 30 extends onto the display surface 11 of the display panel 10, so that the display panel 10 can be fixedly connected with other protective components, such as the cover plate 60, thereby protecting the display panel 10. At the same time, the distribution position of the first colloid 30 on the display panel 10 is staggered with the position of the bonding device 40, and there is no overlap, which can avoid any potential electrical interference or physical obstruction caused by the first colloid 30 to the bonding device 40, so as to ensure the normal operation of the bonding device 40, so that the first colloid 30 can play its adhesion and protection role without affecting the functionality of the display panel 10.

[0039] Please continue reading Figure 3 and Figure 6 In one embodiment, the end surface of the first end 13 of the display panel 10 is covered by the first colloid 30. Specifically, the first colloid 30 not only adheres the first extension portion 22 of the composite film layer 20 and the display panel 10, but also further covers the end surface of the first end 13 of the display panel 10. The continuous adhesion area formed by the first colloid 30 reduces the path for moisture or dust to enter, thereby improving the waterproof and dustproof performance of the display module 100. The first colloid 30 can also prevent external force impact from directly acting on the display panel 10 to a certain extent, thereby protecting the display panel 10.

[0040] In other embodiments, the end surface of the first end 13 of the display panel 10 may not be covered by the first colloid 30 , thereby partially exposing the first end 13 of the display panel 10 so that the first end 13 of the display panel 10 can be connected to other functional components.

[0041] Please continue reading Figure 3 and Figure 6 In one embodiment, the number of bonding devices 40 is multiple, and the multiple bonding devices 40 are arranged at intervals along the extension direction of the side of the display panel 10 and are bonded to the display panel 10. The multiple bonding devices 40 can be used to support various functions of the display panel 10. The bonding devices 40 arranged at intervals can ensure that each bonding device 40 has enough space for electrical connection, and also facilitate the operation during the production and maintenance of the display module 100.

[0042] In one embodiment, the plurality of bonding devices 40 may be of the same type, for example, the plurality of bonding devices 40 may all be chip-on-film, thereby facilitating bonding and manufacturing.

[0043] In other embodiments, the plurality of bonding devices 40 may also be of different types, such as a chip-on-film, a driving circuit, or a sensor, which are bonded and connected to the display panel 10 at the same time, thereby enriching the functions of the display module 100 .

[0044] Please continue reading Figure 3 and Figure 6 In one embodiment, the display module 100 further includes a polarizer 50, which is disposed on one side of the display surface 11 of the display panel 10, and the first end 13 of the display panel 10 extends outward relative to the first end 51 of the polarizer 50, and the first end 51 of the polarizer 50 is spaced apart from the bonding device 40. Specifically, the polarizer 50 is used to filter out part of the polarized light in the natural light, thereby improving the contrast and viewing angle of the display panel 10, thereby improving the display quality of the display panel 10 and making the image clearer and brighter. The first end 51 of the polarizer 50 is spaced apart from the bonding device 40, so that the bonding device 40 will not be blocked by the polarizer 50, which facilitates the connection between the bonding device 40 and the external circuit.

[0045] Please continue reading Figure 3 and Figure 6 In one embodiment, the first colloid 30 extending to the display surface 11 adheres the cover plate 60 and the polarizer 50. The first colloid 30 not only adheres the composite film layer 20 and the display panel 10, but also further ensures the close fit between the display panel 10 and the cover plate 60, thereby improving the structural stability of the entire display module 100.
