[0038] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0039] The embodiments of the present application provide a display module and a bonding method thereof, and a display device. The following are detailed descriptions. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0040] In a first aspect, the present application embodiment provides a display module 100, see Figure 2b The display module 100 includes a display panel 1 and a cover plate assembly 2, wherein the cover plate assembly 2 is arranged on the display side of the display panel 1, and the cover plate assembly 2 includes a cover plate 21, a protective film 22 and a supporting portion 23, wherein the cover plate 21 is attached to the display panel 1, and the protective film 22 is arranged on the side of the cover plate 21 away from the display panel 1; wherein the edge of the cover plate 21 is retracted compared to the edge of the display panel 1; the edge of the protective film 22 exceeds the edge of the cover plate 21 and is flush with the edge of the display panel 1, and the portion of the protective film 22 that exceeds the cover plate 21 forms a suspended portion a; the supporting portion 23 is arranged on the suspended portion a, and supports the protective film 22 and the display panel 1.

[0041] It is known that in the prior art, please refer to Figure 1In order to improve the impact resistance of the display module 100', the cover assembly 2' is bonded to the display side of the display panel 1'. Since the cover assembly 2' is formed by bonding multiple film layers layer by layer, the bonding tolerance between the film layers makes the edge of the display module 100' uneven; after the bonding is completed, the edge of the cover assembly 2' is usually cut to make the edge of the display module 100' neat, thereby improving the fit between the cover assembly 2' and the display panel 1' and further improving the impact resistance of the display module 100'.

[0042] Typically, the cover plate assembly 2' comprises a cover plate 21' and a protective film 22'. The cover plate 21' is attached to the display panel 1', and the protective film 22' is arranged on the side of the cover plate 21' away from the display panel 1'. In order to avoid the cover plate 21' from breaking during cutting, the edge of the cover plate 21' is usually set inward. At this time, the edge of the protective film 22' exceeds the edge of the cover plate 21' and is flush with the edge of the display panel 1', and the protective film 22' exceeds the cover plate 21'. 1' forms the suspended portion a'; after lamination, a gap is formed between the protective film 22' and the display panel 1' at a position corresponding to the suspended portion a'. Based on the self-gravity factor of the protective film 22', the protective film 22' collapses at a position corresponding to the suspended portion a' and adheres to the first optical adhesive layer 3' on the display panel 1', thereby causing the front side of the display module 100' to collapse at its edge, which not only affects the appearance but also reduces the impact resistance of the display module 100'.

[0043] In the present application, the support portion 23 is arranged on the suspended portion a to support the protective film 22 and the display panel 1, which not only can reduce the extent of edge collapse of the protective film 22 and beautify the product appearance, but also can improve the edge strength of the display module 100 and improve the impact resistance of the edge of the display module 100.

[0044] The present application does not impose any specific restrictions on the cover plate 21 and the protective film 22. In one embodiment, the cover plate 21 can be set to UTG (Ultra-Thin Glass in English, and ultra-thin glass in Chinese); the protective film 22 can be set to PW (Protect Window in English, and protective film 22 in Chinese), and the material of the protective film 22 includes but is not limited to one of PET (polyethylene glycol terephthalate in English, and polyethylene terephthalate in Chinese) and CPI (Colorless Polyimide in English, and transparent polyimide in Chinese).

[0045] And it can be known that in the prior art, see Figure 1 The cover plate assembly 2' will be accompanied by a release film 25' when it is received. Usually, a single-layer release barrier film 24' is arranged on the peripheral side of the cover plate 21', and the release film 25' and the protective film 22' are blocked by the single-layer release barrier film 24'. At the same time, a release coating is arranged on the side of the single-layer release barrier film 24' facing the protective film 22', so that the single-layer release barrier film 24' and the protective film 22' are easy to separate, so that the release film 25' is easy to tear off; however, in the bonding process, it is usually necessary to first use plasma technology to clean the film layer, and the gas used for cleaning will make the release coating on the surface of the single-layer release barrier film 24' invalid. Therefore, after the bonding is completed, the invalid single-layer release barrier film 24' will be tightly adhered to the protective film 22', which will still make it difficult for the release film 25' to be torn off from the protective film 22'.

[0046] In an embodiment of the present application, when receiving materials, the cover plate assembly 2 also includes a release portion 24 and a release film 25, the release portion 24 is arranged on the side of the support portion 23 away from the protective film 22, and the release film 25 is arranged on the side of the release portion 24 away from the support portion 23, and the release film 25 covers the cover plate 21 and the release portion 24.

[0047] Before lamination, it is usually necessary to use plasma technology to clean each film layer. Since the release portion 24 is covered with the support portion 23, the gas used for cleaning will not affect the release portion 24, nor will it affect the separation of the release portion 24 from the support portion 23, so that the release film 25 is extremely easy to tear off.

[0048] See also Figure 2a and Figure 2b , Figure 2a A schematic diagram of a first film layer of a cover plate assembly 2 provided in an embodiment of the present application; Figure 2b Schematic diagram of the first film layer of the display module 100 provided in the embodiment of the present application. In the first embodiment of the present application, the support portion 23 includes a second support adhesive layer 234, and the second support adhesive layer 234 is disposed on the suspended portion a, and the second support adhesive layer 234 supports the protective film 22 and the display panel 1.

[0049] Please note that Figure 2aBefore lamination, the incoming material of the cover assembly 2 includes the release portion 24 and the release film 25, the release portion 24 includes a first release substrate 241 and a first release adhesive layer 242 which are stacked, the first release substrate 241 is connected to the second supporting adhesive layer 234, and the first release adhesive layer 242 is connected to the release film 25; wherein the adhesion between the second supporting adhesive layer 234 and the first release substrate 241 is less than the adhesion between the first release adhesive layer 242 and the release film 25; therefore, when tearing off the release film 25, the first release substrate 241 is easier to separate from the second supporting adhesive layer 234, thereby reducing the difficulty of tearing off the release film 25.

[0050] And, after tearing off the release film 25, please refer to Figure 2b The second supporting adhesive layer 234 is retained on the protective film 22. After the cover plate assembly 2 is attached to the display panel 1, the second supporting adhesive layer 234 can contact the display panel 1, thereby supporting the protective film 22, which can not only reduce the extent of the edge collapse of the protective film 22 and beautify the product appearance, but also improve the edge strength of the display module 100 and improve the impact resistance of the display module 100.

[0051] However, it can be known that, in the first embodiment, since only the second supporting rubber layer 234 is retained on the protective film 22, the supporting property of the supporting portion 23 is poor. When being bent or squeezed, the second supporting rubber layer 234 will have the phenomenon of rubber overflowing, and as the product is used for a longer time, the stiffness of the second supporting rubber layer 234 will be greatly reduced. These will cause the second supporting rubber layer 234 to partially collapse, thereby failing to support the protective film 22.

[0052] See also Figure 3a and Figure 3b , Figure 3a A schematic diagram of a second film layer of the cover plate assembly 2 provided in an embodiment of the present application; Figure 3b A schematic diagram of a second film layer of the display module 100 provided in an embodiment of the present application. In the second embodiment, the support portion 23 includes a first support substrate 231 and a first support adhesive layer 232, the first support substrate 231 is disposed on the suspended portion a, the first support adhesive layer 232 is disposed on a side of the first support substrate 231 away from the protective film 22, and the first support adhesive layer 232 connects the first support substrate 231 and the display panel 1.

[0053] The difference from the first embodiment is that in the second embodiment, refer to Figure 3aBefore lamination, the incoming material of the cover assembly 2 includes the release portion 24 and the release film 25, the release portion 24 includes a second release substrate 243 and a second release adhesive layer 244 stacked, the second release substrate 243 is connected to the first supporting adhesive layer 232, and the second release adhesive layer 244 is connected to the release film 25; wherein the adhesion between the first supporting adhesive layer 232 and the second release substrate 243 is less than the adhesion between the second release substrate 243 and the release film 25; therefore, when tearing off the release film 25, the second release substrate 243 is easier to separate from the first supporting adhesive layer 232, thereby reducing the difficulty of tearing off the release film 25.

[0054] And, after tearing off the release film 25, please refer to Figure 3b , the first supporting substrate 231 and the first supporting adhesive layer 232 are retained on the protective film 22. After the cover plate assembly 2 is attached to the display panel 1, the first supporting adhesive layer 232 can contact the display panel 1. The first supporting substrate 231 and the first supporting adhesive layer 232 can jointly support the protective film 22, which can not only reduce the extent of the edge collapse of the protective film 22 and beautify the product appearance, but also improve the edge strength of the display module 100 and improve the impact resistance of the display module 100. Compared with the first embodiment, the first supporting substrate 231 in the second embodiment makes the supporting portion 23 have stronger support and can provide better support for the protective film 22.

[0055] It can be known that, in some embodiments, the display panel 1 adopts a POP (full name: Panel on Plastic, Chinese abbreviation: the display panel 1 is made on a plastic substrate) structure, and the display panel 1 includes a display layer 11 and a plastic base layer 12, and the plastic base layer 12 is located on the display side of the display layer 11; the first optical adhesive layer 3 is provided on the side of the plastic base layer 12 away from the display layer 11. Generally, the edge of the first optical adhesive layer 3 can be arranged flush with the edge of the display panel 1, or can be arranged inward relative to the edge of the display panel 1.

[0056] Based on the first embodiment and the second embodiment, the cover plate assembly 2 is disposed on the side of the first optical adhesive layer 3 away from the display panel 1, and the cover plate 21 is connected to the display panel 1 through the first optical adhesive layer 3, and the first supporting adhesive layer 232 or the second supporting adhesive layer 234 of the supporting portion 23 is connected to the display panel 1. In this way, the display module 100 described in the first embodiment and the second embodiment can be applied to "the edge of the first optical adhesive layer 3 can be arranged flush with the edge of the display panel 1", and the supporting portion 23 is adhered to the first optical adhesive layer 3; it can also be applied to "the edge of the first optical adhesive layer 3 is arranged inwardly relative to the edge of the display panel 1", and the supporting portion 23 is adhered to the display panel 1, thereby increasing the adaptability diversity of the display module 100.

[0057] In one embodiment, the edge of the first optical adhesive layer 3 is retracted compared to the edge of the display panel 1, and the projection of the first optical adhesive layer 3 on the display panel 1 and the projection of the support portion 23 on the display panel 1 are offset, and the support portion 23 is adhered to the plastic base layer 12.

[0058] Based on the first embodiment and the second embodiment, the present application does not impose any specific restrictions on the method of achieving "the adhesion between the support portion 23 and the release portion 24 is less than the adhesion between the release portion 24 and the release film 25". It can be achieved by setting the adhesion strength of the first support adhesive layer 232 to be less than the adhesion strength of the second release adhesive layer 244, or the adhesion strength of the second support adhesive layer 234 to be less than the adhesion strength of the first release adhesive layer 242; it can also be achieved by setting a release coating on the surface of the first release substrate 241 or the second release substrate 243 facing the support portion 23; it can also be achieved by setting the adhesion strength of the adhesive layer of the support portion 23 to be less than the adhesion strength of the adhesive layer of the release portion 24, and also setting a release coating on the surface of the first release substrate 241 or the second release substrate 243 facing the support portion 23. Different solutions can be selected according to different usage scenarios and requirements.

[0059] See also Figure 4a and Figure 4b , Figure 4a A schematic diagram of a third film layer of the display module 100 provided in an embodiment of the present application; Figure 4b A third film layer schematic diagram of the display device 1000 provided in the embodiment of the present application. In the third embodiment, the support portion 23 includes a second support substrate 233, and the second support substrate 233 is disposed on the suspended portion a.

[0060] The difference from the second embodiment is that in the third embodiment of the present application, please refer to Figure 4a Before lamination, the incoming material of the cover assembly 2 includes the release portion 24 and the release film 25, the release portion 24 includes a third release adhesive layer 246 and a fourth release adhesive layer 247 which are stacked, and a third release substrate 245 sandwiched therebetween, the third release adhesive layer 246 is connected to the second supporting substrate 233, and the fourth release adhesive layer 247 is connected to the release film 25; wherein the adhesion between the third release adhesive layer 246 and the second supporting substrate 233 is less than the adhesion between the fourth release adhesive layer 247 and the release film 25; therefore, when tearing off the release film 25, the third release adhesive layer 246 is easier to separate from the second supporting substrate 233, thereby reducing the difficulty of tearing off the release film 25.

[0061] And, after tearing off the release film 25, please refer to Figure 4b The second supporting substrate 233 is retained on the protective film 22. After the cover plate assembly 2 is attached to the display panel 1, the second supporting substrate 233 is located between the protective film 22 and the display panel 1, thereby supporting the protective film 22. This can not only reduce the extent of the edge collapse of the protective film 22 and beautify the product appearance, but also improve the edge strength of the display module 100 and improve the impact resistance of the display module 100.

[0062] In combination with the above embodiments, it can be known that the display panel 1 adopts a POP structure, the display side of the display panel 1 is provided with the first optical adhesive layer 3, the cover plate assembly 2 is provided on the side of the first optical adhesive layer 3 away from the display panel 1, and the cover plate 21 is connected to the display panel 1 through the first optical adhesive layer 3. Since only the second supporting substrate 233 is retained on the protective film 22 after the release film 25 is torn off, the supporting portion 23 has no adhesion. In order to ensure the lamination stability of the display panel 1, in the third embodiment, the edge of the first optical adhesive layer 3 is flush with the edge of the display panel 1, and the second supporting substrate 233 is adhered and fixed to the first optical adhesive layer 3.

[0063] Similarly, the present application does not impose any specific restrictions on the method of achieving "the adhesion between the third release adhesive layer 246 and the second supporting substrate 233 is less than the adhesion between the fourth release adhesive layer 247 and the release film 25". It can be achieved by setting the adhesion strength of the third release adhesive layer 246 to be less than the adhesion strength of the fourth release adhesive layer 247; it can also be achieved by setting a release coating on the surface of the second supporting substrate 233 facing the third release adhesive layer 246; it can also be achieved by setting the adhesion strength of the third release adhesive layer 246 to be less than the adhesion strength of the fourth release adhesive layer 247, and also setting a release coating on the surface of the second supporting substrate 233 facing the third release adhesive layer 246. Different solutions can be selected according to different usage scenarios and requirements.

[0064] The present application does not impose any specific restrictions on the materials of the first supporting substrate 231 and the second supporting substrate 233. The materials of the first supporting substrate 231 and the second supporting substrate 233 may be the same or different. The materials of the first supporting substrate 231 and the second supporting substrate 233 both include PET (full name in English: Polyethylene Terephthalate, Chinese abbreviation: polyethylene terephthalate) or PI (full name in English: Polyimide, Chinese abbreviation: polyimide).

[0065] The present application does not impose any specific restrictions on the materials of the first release substrate 241, the second release substrate 243 and the third release substrate 245. The materials of the three may be the same or different, and all include PET (full name in English: Polyethylene Terephthalate, Chinese abbreviation: polyethylene terephthalate) or PI (full name in English: Polyimide, Chinese abbreviation: polyimide).

[0066] In the manufacturing process of the display module 100 , based on the bonding accuracy, the relative displacement of each film layer when the folding screen is in a folded state, and the bonding tolerance, the distance between the support portion 23 and the cover plate 21 is greater than or equal to 0.2 mm.

[0067] Following the above, before the cover plate assembly 2 and the display panel 1 are bonded, the cover plate assembly 2 is a two-in-one material. That is to say, the cover plate 21, the support portion 23, the release portion 24 and the release film 25 are a whole, and the protective film 22 is bonded to the cover plate 21 to form a complete cover plate assembly 2. In the actual bonding process, in order to avoid the phenomenon of the protective film 22 being falsely bonded, the total thickness of the support portion 23 and the release portion 24 is usually less than or equal to the thickness of the cover plate 21. During the bonding process, when the release film 25 is torn off, the release portion 24 will be taken away, leaving only the support portion 23 on the protective film 22, so the thickness of the support portion 23 is less than the thickness of the cover plate 21.

[0068] Furthermore, as mentioned above, after the cover plate assembly 2 and the display panel 1 are bonded together, the edges need to be cut to ensure that the edges of the display module 100 are aligned; to ensure that the edges of the support portion 23 remain consistent, the edge of the support portion 23 on one side away from the cover plate 21 is flush with the edge of the display panel 1; that is, after the cover plate assembly 2 and the display panel 1 are bonded together, the edges of the protective film 22 and the support portion 23 are flush, and the protective film 22 and the support portion 23 can be cut at the same time so that the edges of the protective film 22, the support portion 23 and the display panel 1 remain flush; in this way, not only can the edges of the display module 100 after bonding be ensured to be aligned, but also after cutting, the support portion 23 also reserves enough parts to support the protective film 22 and the display panel 1.

[0069] In one embodiment, the display module 100 also includes a backplane assembly 4, which is arranged on the back side of the display panel 1. The backplane assembly 4 includes a stacked backplane 41 and a backlight source 42. The backplane 41 is arranged close to the display panel 1, and the backlight source 42 is located on the side of the backplane 41 away from the display panel 1.

[0070] In a third aspect, based on the structure of the display module 100 described above, please refer to Figure 5 The embodiment of the present application further provides a method for attaching a display module 100, and the method for attaching a display module 100 includes:

[0071] S10: providing a display panel 1;

[0072] S20: Provide a cover plate assembly 2; wherein the cover plate assembly 2 comprises a cover plate 21, a protective film 22, a support portion 23, a release portion 24 and a release film 25, wherein the protective film 22 and the release film 25 are arranged on both sides of the cover plate 21, and the edge of the cover plate 21 is arranged inwardly relative to the protective film 22, the support portion 23 is arranged on the protective film 22 and is located on the outer side of the cover plate 21, the release portion 24 is arranged on the release film 25 and is located on the outer side of the cover plate 21, and the release portion 24 is connected to the support portion 23;

[0073] S30: Cleaning the cover plate assembly 2 and the display panel 1;

[0074] S40: tearing off the release film 25 and the release portion 24 from the cover plate 21;

[0075] S50: Lay the cover plate assembly 2 on the display panel 1, wherein the cover plate 21 is laminated to the display side of the display panel 1, the protective film 22 is located on the side of the cover plate 21 away from the display panel 1, and the support portion 23 is located on the outer side of the cover plate 21 and supports the protective film 22 and the display panel 1.

[0076] When the materials are received, the cover plate assembly 2 includes a release portion 24 and a release film 25. The release portion 24 is arranged on the side of the support portion 23 away from the protective film 22, and the release film 25 is arranged on the side of the release portion 24 away from the support portion 23. The release film 25 covers the cover plate 21 and the release portion 24. Before bonding, it is usually necessary to first use plasma technology to clean each film layer. Since the release portion 24 is covered with the support portion 23, the gas used for cleaning will not affect the release portion 24, nor will it affect the separation of the release portion 24 from the support portion 23, so that the release film 25 is extremely easy to tear off.

[0077] During lamination, the release film 25 and the release portion 24 are torn off from the cover plate 21. At this time, the cover plate assembly 2 is left with the cover plate 21, the protective film 22 and the support portion 23. The cover plate assembly 2 is laminated to the display panel 1, the cover plate 21 is laminated to the display side of the display panel 1, the protective film 22 is located on the side of the cover plate 21 away from the display panel 1, and the support portion 23 is located on the outside of the cover plate 21 and supports the protective film 22 and the display panel 1.

[0078] By arranging the support portion 23 on the suspended portion a, the protective film 22 and the display panel 1 are supported, which not only reduces the extent of edge collapse of the protective film 22 and beautifies the product appearance, but also improves the edge strength of the display module 100 and improves the impact resistance of the edge of the display module 100.

[0079] In a third aspect, the embodiments of the present application further provide a display device, the display device comprising a display module 100.
