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

[0039] The present application provides a display module and a display device. The following will be described in detail. It should be noted that the order of the following embodiments is not limited as the preferred order of the embodiments.

[0040] In a first aspect, the present application provides a display module 100, as shown in FIG. 1A. Figure 2b The display module 100 includes a display panel 1 and a cover plate assembly 2. The cover plate assembly 2 is arranged on the display side of the display panel 1. The cover plate assembly 2 includes a cover plate 21, a protective film 22, and a support part 23. The cover plate 21 is attached to the display panel 1. The protective film 22 is arranged on the side of the cover plate 21 away from the display panel 1. The edge of the cover plate 21 is arranged inwardly compared with the edge of the display panel 1. The edge of the protective film 22 exceeds the edge of the cover plate 21 and is arranged flush with the edge of the display panel 1. The part of the protective film 22 exceeding the cover plate 21 forms a hanging part a. The support part 23 is arranged on the hanging part a and supports the protective film 22 and the display panel 1.

[0041] It can be known that in the prior art, as shown in FIG. 1A, Figure 1In order to improve the impact resistance of the display module 100', the cover plate assembly 2' is attached to the display side of the display panel 1'. Since the cover plate assembly 2' is formed by attaching multiple film layers one by one, the attachment tolerance between the film layers makes the edges of the display module 100' uneven. After the attachment is completed, the edges of the cover plate assembly 2' are usually cut to make the edges of the display module 100' even, thereby improving the attachment of the cover plate assembly 2' to the display panel 1' and further improving the impact resistance of the display module 100'.

[0042] Generally, the cover plate assembly 2' includes two parts of 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 being broken during cutting, the edges of the cover plate 21' are usually arranged to be inwardly recessed. At this time, the edges of the protective film 22' protrude beyond the edges of the cover plate 21' and are arranged flush with the edges of the display panel 1'. The part of the protective film 22' that protrudes beyond the cover plate 21' forms the overhanging portion a'. After the attachment, a gap is formed between the protective film 22' and the display panel 1' at the position corresponding to the overhanging portion a'. Due to the self-gravity of the protective film 22', the protective film 22' collapses at the position corresponding to the overhanging portion a' and adheres to the first optical adhesive layer 3' on the display panel 1', thereby causing the front surface of the display module 100' to collapse at the edge position. This 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 at the overhanging portion a' to support the protective film 22 and the display panel 1'. This not only reduces the collapse of the edges of the protective film 22 and beautifies the appearance of the product, but also improves the edge strength of the display module 100 and improves the edge impact resistance of the display module 100.

[0044] The present application does not specifically limit the cover plate 21 and the protective film 22. In an embodiment, the cover plate 21 can be arranged as UTG (English full name: Ultra-Thin Glass, Chinese abbreviation: ultra-thin glass). The protective film 22 can be arranged as PW (English full name: protect window, Chinese abbreviation: cover plate 21 material protective film 22). The material of the protective film 22 includes but is not limited to one of PET (English full name: polyethylene glycol terephthalate, Chinese abbreviation: polyethylene terephthalate) and CPI (English full name: Colorless Polyimide, Chinese abbreviation: transparent polyimide).

[0045] And it can be known that, in the prior art, referring to Figure 1 , the cover plate assembly 2' is attached with a release film 25' when it is delivered, and a single-layer release barrier film 24' is usually arranged on the peripheral side of the cover plate 21', which blocks the release film 25' and the protective film 22' through the single-layer release barrier film 24'. At the same time, the side of the single-layer release barrier film 24' facing the protective film 22' is provided with a release coating, so that the single-layer release barrier film 24' is easy to separate from the protective film 22', so that the release film 25' is easy to tear off; but because in the lamination process, it is usually necessary to clean the film layer by using plasma technology, and the gas used for cleaning will cause the release coating on the surface of the single-layer release barrier film 24' to fail, so after the lamination is completed, the single-layer release barrier film 24' which has failed will be tightly adhered to the protective film 22', which will still cause the release film 25' to be difficult to tear off from the protective film 22'.

[0046] In the embodiment of the present application, when delivered, the cover plate assembly 2 further comprises a release part 24 and a release film 25, the release part 24 is arranged on the side of the support part 23 away from the protective film 22, and the release film 25 is arranged on the side of the release part 24 away from the support part 23, and the release film 25 covers the cover plate 21 and the release part 24.

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

[0048] Please refer to Figure 2a and Figure 2b , Figure 2a the first film layer schematic diagram of the cover plate assembly 2 provided by the embodiment of the present application; Figure 2b the first film layer schematic diagram of the display module 100 provided by the embodiment of the present application. In the first embodiment of the present application, the support part 23 comprises a second support adhesive layer 234, the second support adhesive layer 234 is arranged on the overhanging part a, and the second support adhesive layer 234 supports the protective film 22 and the display panel 1.

[0049] It should be noted that, please refer to Figure 2aBefore the lamination, the cover plate assembly 2 includes the release part 24 and the release film 25, the release part 24 includes the first release substrate 241 and the first release adhesive layer 242 which are arranged in a stack, the first release substrate 241 is connected with the second support adhesive layer 234, and the first release adhesive layer 242 is connected with the release film 25; wherein the adhesion between the second support 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; thus when the release film 25 is peeled off, the first release substrate 241 is more likely to be separated from the second support adhesive layer 234, thereby reducing the difficulty of peeling off the release film 25.

[0050] After the release film 25 is peeled off, please refer to Figure 2b , the second support adhesive layer 234 is reserved on the protective film 22, and after the cover plate assembly 2 is laminated with the display panel 1, the second support adhesive layer 234 can be in contact with the display panel 1, thereby supporting the protective film 22, which not only can reduce the collapse amplitude of the edge of the protective film 22, beautify the product appearance, but also can 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 support adhesive layer 234 is reserved on the protective film 22, the supportability of the support part 23 is poor, and when subjected to bending and extrusion, the second support adhesive layer 234 will have the phenomenon of adhesive material overflow, and with the increase of product use time, the stiffness of the second support adhesive layer 234 will decrease greatly, which will cause the second support adhesive layer 234 to have local collapse defects, thereby failing to support the protective film 22.

[0052] Please refer to Figure 3a and Figure 3b , Figure 3a the second film layer schematic view of the cover plate assembly 2 provided in the embodiments of the present application; Figure 3b the second film layer schematic view of the display module 100 provided in the embodiments of the present application. In the second embodiment, the support part 23 includes the first support substrate 231 and the first support adhesive layer 232, the first support substrate 231 is arranged on the overhanging part a, the first support adhesive layer 232 is arranged on the 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, please refer to Figure 3aBefore the lamination, the cover plate assembly 2 includes the release part 24 and the release film 25, the release part 24 includes the second release substrate 243 and the second release adhesive layer 244 which are arranged in a stack, the second release substrate 243 is connected with the first supporting adhesive layer 232, and the second release adhesive layer 244 is connected with the release film 25; 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 the release film 25 is peeled off, the second release substrate 243 is more easily separated from the first supporting adhesive layer 232, thereby reducing the difficulty of peeling off the release film 25.

[0054] After the release film 25 is peeled off, referring to Figure 3b , the first supporting substrate 231 and the first supporting adhesive layer 232 are retained on the protective film 22, and after the cover plate assembly 2 is laminated with the display panel 1, the first supporting adhesive layer 232 can be in contact with the display panel 1, and the first supporting substrate 231 and the first supporting adhesive layer 232 can jointly support the protective film 22, which not only can reduce the 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 display module 100. Compared with the first embodiment, the first supporting substrate 231 in the second embodiment makes the supporting part 23 have stronger supporting property, 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 (Panel on Plastic) structure, and the display panel 1 includes a display layer 11 and a plastic base layer 12 which is located on the display side of the display layer 11; the plastic base layer 12 is provided with a first optical adhesive layer 3 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 to be inwardly recessed relative to the edge of the display panel 1.

[0056] Based on the first and second embodiments, the cover plate assembly 2 is arranged on the side of the first optical adhesive layer 3 away from the display panel 1, and the cover plate 21 is connected with the display panel 1 through the first optical adhesive layer 3, and the first support adhesive layer 232 or the second support adhesive layer 234 of the support part 23 is connected with the display panel 1. In this way, the display module 100 in the first and second embodiments can be applied to both the case where the edge of the first optical adhesive layer 3 is arranged flush with the edge of the display panel 1, and the support part 23 is adhered to the first optical adhesive layer 3, and the case where the edge of the first optical adhesive layer 3 is arranged inwardly relative to the edge of the display panel 1, and the support part 23 is adhered to the display panel 1, thereby increasing the adaptation diversity of the display module 100.

[0057] In an embodiment, the edge of the first optical adhesive layer 3 is arranged inwardly relative to the edge of the display panel 1, and the projection of the first optical adhesive layer 3 on the display panel 1 is arranged in a staggered manner with the projection of the support part 23 on the display panel 1, and the support part 23 is adhered to the plastic base layer 12.

[0058] Based on the first and second embodiments, the present application does not make specific limitations on the way of realizing that the adhesion between the support part 23 and the release part 24 is less than the adhesion between the release part 24 and the release film 25. It can be realized 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 realized by setting a release coating on the side surface of the first release substrate 241 or the second release substrate 243 facing the support part 23; it can also be realized by both setting the adhesion strength of the adhesive layer of the support part 23 to be less than the adhesion strength of the adhesive layer of the release part 24, and setting a release coating on the side surface of the first release substrate 241 or the second release substrate 243 facing the support part 23. Different solutions can be selected according to different use scenarios and requirements.

[0059] Please refer to Figure 4a and Figure 4b , Figure 4a the third film layer schematic diagram of the display module 100 provided in the embodiments of the present application; Figure 4b the third film layer schematic diagram of the display device 1000 provided in the embodiments of the present application. In the third embodiment, the support part 23 comprises a second support substrate 233, and the second support substrate 233 is arranged on the overhanging part a.

[0060] The difference between the third embodiment of the present application and the second embodiment is that, in the third embodiment of the present application, please refer toFigure 4a Before the lamination, the cover plate assembly 2 includes the release part 24 and the release film 25, the release part 24 includes the third release adhesive layer 246 and the fourth release adhesive layer 247 which are arranged in a stack, and the third release substrate 245 which is sandwiched between the third release adhesive layer 246 and the fourth release adhesive layer 247, the third release adhesive layer 246 is connected with the second support substrate 233, and the fourth release adhesive layer 247 is connected with the release film 25; the adhesion between the third release adhesive layer 246 and the second support substrate 233 is less than the adhesion between the fourth release adhesive layer 247 and the release film 25; therefore, when the release film 25 is peeled off, the third release adhesive layer 246 is more easily separated from the second support substrate 233, thereby reducing the difficulty of peeling off the release film 25.

[0061] After the release film 25 is peeled off, the second support substrate 233 is retained on the protective film 22, and after the cover plate assembly 2 is laminated with the display panel 1, the second support substrate 233 is between the protective film 22 and the display panel 1, thereby supporting the protective film 22, which not only reduces the 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 display module 100. Figure 4b As can be seen from the above embodiments, the display panel 1 adopts a POP structure, the first optical adhesive layer 3 is arranged on the display side of the display panel 1, the cover plate assembly 2 is arranged on the side of the first optical adhesive layer 3 away from the display panel 1, and the cover plate 21 is connected with the display panel 1 through the first optical adhesive layer 3. Since only the second support substrate 233 is retained on the protective film 22 after the release film 25 is peeled off, the support part 23 has no adhesion, and 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 support substrate 233 is adhesively fixed with the first optical adhesive layer 3.

[0062]

[0063] ​Similarly, the application does not make specific restrictions on the way to achieve "the adhesion between the third release adhesive layer 246 and the second support substrate 233 is less than the adhesion between the fourth release adhesive layer 247 and the release film 25". It can be that the adhesion strength of the third release adhesive layer 246 is set to be less than the adhesion strength of the fourth release adhesive layer 247; it can also be that a release coating is arranged on the side surface of the second support substrate 233 facing the third release adhesive layer 246; it can also be that both the adhesion strength of the third release adhesive layer 246 is set to be less than the adhesion strength of the fourth release adhesive layer 247, and a release coating is arranged on the side surface of the second support substrate 233 facing the third release adhesive layer 246. Different solutions can be selected according to different use scenarios and requirements.

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

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

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

[0067] In the light of the above, before the cover plate assembly 2 and the display panel 1 are laminated, the cover plate assembly 2 is a two-in-one material. That is, the cover plate 21, the support part 23, the release part 24, and the release film 25 are an integral whole, and the protective film 22 is laminated with the cover plate 21 to form a complete cover plate assembly 2. In the actual lamination process, in order to avoid the phenomenon of virtual lamination of the protective film 22, the total thickness of the support part 23 and the release part 24 is less than or equal to the thickness of the cover plate 21. In the lamination process, the release film 25 is torn away with the release part 24, and only the support part 23 is left on the protective film 22, so the thickness of the support part 23 is less than the thickness of the cover plate 21.

[0068] In addition, as described above, after the cover plate assembly 2 and the display panel 1 are laminated, the edge needs to be cut to ensure that the edge of the display module 100 is neat; in order to ensure that the edge of the support part 23 is consistent, the edge of the side away from the cover plate 21 of the support part 23 is flush with the edge of the display panel 1; that is, after the cover plate assembly 2 and the display panel 1 are laminated, the edges of the protective film 22 and the support part 23 are flush, and the protective film 22 and the support part 23 can be cut at the same time, so that the edges of the protective film 22, the support part 23, and the display panel 1 are flush; in this way, not only can the edge of the display module 100 after lamination be ensured to be neat, but also after cutting, the support part 23 also reserves enough part to support the protective film 22 and the display panel 1.

[0069] In an embodiment, the display module 100 further comprises a back plate assembly 4, which is arranged on the back side of the display panel 1. The back plate assembly 4 comprises a back plate 41 and a backlight 42 arranged in layers. The back plate 41 is arranged close to the display panel 1, and the backlight 42 is located on the side of the back plate 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 also provides a lamination method of a display module 100. The lamination method of the display module 100 comprises the following steps:

[0071] S10: providing a display panel 1;

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

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

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

[0075] S50: bonding the cover plate assembly 2 and the display panel 1, wherein the cover plate 21 is bonded 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 part 23 is located outside the cover plate 21 and supports the protective film 22 and the display panel 1.
