Description

AREA OF TECHNOLOGY

[0001] The present disclosure relates to the field of display technology, in particular to a display cover plate and a method for manufacturing the same, a display module and a method for manufacturing the same, and a display device. STATE OF THE ART

[0002] In related technologies, OLEDs (Organic Light-Emitting Diodes) are widely used in mobile displays as an emerging and rapidly growing light-emitting device due to their self-illuminating properties, high contrast, and flexibility. For end-device displays, such as those used in mobile phones, those with an ultra-high aspect ratio and four curved surfaces will be at the forefront of the competition for future display screens.

[0003] A four-curve screen refers to a display screen where the left, right, top, and bottom edges are curved to one side of the screen with a specific radius of curvature. Four-curve screens have an attractive appearance, are very grippy, and can achieve an ultra-high aspect ratio when viewed from the front. However, the design of the top panel of a four-curve screen creates a curved surface with a specific spherical angle at the four corner areas where the curved surfaces intersect. The stress and strain in these areas are unevenly distributed in the two-dimensional direction, exhibiting anisotropy. Therefore, an anti-reflective film (such as a polarizer) applied to the top panel would easily lead to problems such as wrinkles, insufficient contact, and gaps.

[0004] It should be noted that the information disclosed in the above paragraphs is only intended to improve the understanding of the background of the present disclosure and may therefore include information that does not represent prior art already known to the person skilled in the art. SUMMARY

[0030] Exemplary embodiments are now described in more detail with reference to the drawings. However, these exemplary embodiments can be implemented in a variety of ways and should not be interpreted as being limited to those presented herein. Rather, the provision of these embodiments makes the present disclosure comprehensive and complete and conveys ideas of the exemplary embodiments to those skilled in the art in an understandable manner.

[0032] Terms like "one," "an," "the," "said," and "at least one" are used to indicate the presence of one or more elements / components / etc. Terms like "include" and "comprehensive" are used to indicate open inclusion and mean that additional elements / components / etc. are present beyond those listed. Terms like "first," "second," "third," etc., are used only as markers and not to limit the number of objects.

[0033] Embodiments of the present disclosure provide a schematic diagram of the structure of a display cover plate 10. As in Fig. As shown in Figure 1, the display cover plate 10 comprises an antireflective layer 11 and an injection layer 12. The antireflective layer 11 comprises an antireflective film 111 and a first adhesive layer 112. The antireflective film 111 includes a curved surface region (at least part of the antireflective film 111 has a curved surface shape), and the antireflective film 111 has a convex surface and a concave surface. The first adhesive layer 112 is located on the side of the convex surface 111a of the antireflective film. The injection layer 12 is located on a side of the first adhesive layer 112 furthest from the antireflective film 111 and is formed by an injection molding process. The injection layer 12 has a curved surface shape that is adapted to the curved surface region of the antireflective film 111.The injection layer 12 has a convex surface and a concave surface, and the concave surface 12b of the injection layer is directed towards the first adhesive layer 112.

[0034] In some embodiments of the present disclosure, a hard-structured injection layer 12 is formed on the side of the convex surface 112a of the first adhesive layer by injection molding, thereby achieving bonding between the antireflective film 111 and the injection layer 12 and improving the structural strength of the display cover plate 10. As a result, the bonding in the related technology, which is between the curved antireflective film 111 and the pre-formed curved protective layer (glass substrate, resin substrate, etc.), is avoided, thereby reducing adhesive wrinkles at the corners of the antireflective film 111, which lead to gaps and insufficient contact, and improving the yield of the display cover plate 10.Furthermore, for the cen anti-reflective film 111, during the formation of the injection layer 12 by the injection molding process, the injection material can effectively compress the anti-reflective layer 11, and then furthermore shape the curved surface area of ​​the anti-reflective layer 11 with the assistance of the injection mold 19, in order to reduce the requirements for the size and / or shape of the curved surface shape of the anti-reflective layer 11 and at the same time ensure the yield of the display cover plate 10.

[0035] In some embodiments, the display cover plate 10 involved in the present disclosure can be a cover plate with double curved surfaces, as in Fig. Figure 2 shows a cover plate with four curved surfaces, as in Fig. 3 shown, or a cover plate with a spherical crown, as in Fig. 4 shown.

[0036] The antireflective film 111 can be a film layer with an antireflective function, such as a polarizer, and the antireflective film 111 is plastic or stretchable to avoid creases at the corners during molding. The first adhesive layer 112 can be an OCA optical adhesive, an OCR optical adhesive, a hot-melt adhesive, etc. The injection material of the injection layer 12 can be one or more fusible materials, such as polyimide, polyethylene terephthalate, polymethyl methacrylate, polyethylene naphthalate, polyurethane, etc. In some embodiments, the injection material of the injection layer 12 can also be other materials, as long as the materials can ensure that the injection layer 12 has a certain structural strength after injection, which are not limited in embodiments of the present disclosure.

[0037] In some embodiments, the thickness of the injection layer 12 is greater than or equal to 200 micrometers and less than or equal to 700 micrometers. As a result, for the injection layer 12 with a specific structural strength, the maximum thickness is limited to achieve a lightweight and thin display cover plate 10, while simultaneously the minimum thickness is limited to ensure the structural strength of the injection layer 12, thus guaranteeing the structural strength of the display cover plate 10. In some embodiments, the thickness of the injection layer 12 can be 200 micrometers, 250 micrometers, 300 micrometers, 350 micrometers, 400 micrometers, 500 micrometers, 600 micrometers, or 700 micrometers.

[0038] In some embodiments, the stiffness modulus of the injection layer 12 is greater than or equal to 1 GPa to ensure the structural strength of the injection layer 12, thereby ensuring the structural stability of the display cover plate 10. In some embodiments, the stiffness modulus of the injection layer 12 is 1 GPa, 2 GPa, 3 GPa, 4 GPa, 5 GPa, or 6 GPa.

[0039] For the antireflective layer 11 described above, an antireflective film 111 can first be placed in a forming mold 18 (such as a hot-pressure forming mold, a high-pressure forming mold, etc.) to form the antireflective film 111 into a curved surface shape, and then a first adhesive layer 112 can be applied or bonded to the side of the convex surface 111a of the antireflective film being formed to obtain the curved antireflective layer 11. In some embodiments, as in Fig. As shown in Figure 5, a first adhesive layer 112 is first applied or glued to one side of the antireflective film 111, and then the antireflective film 111 and the first adhesive layer 112 as a whole are placed in the mold 18 to form it into a curved surface shape and to obtain the antireflective layer 11, which includes a curved surface area (at least part of the antireflective layer 11 has a curved surface shape), as shown in Figure 5. Fig. 6 shown.

[0040] In some embodiments, when placing the anti-reflective film 111 and the first adhesive layer 112 as a whole into the mold 18 for demolding, a side of the first adhesive layer 112 away from the anti-reflective film 111 is provided with a release paper to prevent the first adhesive layer 112 from being stuck to the mold 18 and being difficult to demold.

[0041] When the injection layer 12 is formed in the injection mold 19 by injection molding, the release paper on the first adhesive layer 112 is removed to obtain the injection layer 12, while the bond between the injection layer 12 and the first adhesive layer 112 is achieved in order to reduce the process steps used for the display cover plate 10 and to improve the manufacturing efficiency of the display cover plate 10.

[0042] It should be noted that for the display cover plate 10 described above, which comprises the anti-reflective film 111 and the injection layer 12, injection molding can be carried out directly in the injection mold 19 based on the anti-reflective layer 11 to obtain the display cover plate 10 comprising the injection layer 12. In some embodiments, as in Fig. As shown in Figure 7, a curved auxiliary film layer 17 can also be prefabricated so that injection molding in the injection mold 19 can be carried out based on the auxiliary film layer 17 and the anti-reflective layer 11 to obtain the display cover plate 10, which comprises the anti-reflective film 111, the injection layer 12, and the auxiliary film layer 17. The auxiliary film layer 17 can then be peeled off by a specific process.

[0043] In some embodiments, such as in Fig. As shown in Figure 8, the auxiliary film layer 17 comprises an auxiliary base film 171 and a fourth adhesive layer 172. The auxiliary base film 171 has a curved surface shape adapted to the antireflective film 111, and the fourth adhesive layer 172 is located on the side of the concave surface of the auxiliary base film 171. The auxiliary film layer 17 and the antireflective layer 11 are then placed in an injection mold 19 (which comprises a concave mold 191 and a convex mold 192). The convex surface of the auxiliary film layer 17 is attached to the concave mold 191 of the injection mold 19, and the concave surface of the antireflective layer 11 is attached to the convex mold 192 of the injection mold 19. Then injection molding takes place between the concave surface of the auxiliary film layer 17 and the convex surface of the anti-reflective layer 11 (i.e.between the first adhesive layer 112 and the fourth adhesive layer 172), to obtain the display cover plate 10, which includes the injection layer 12 and the auxiliary film layer 17, as shown in . Fig. 7 is shown. Then, as in Fig. 9 shown, the auxiliary film layer 17 peeled off to reveal the in Fig. 1. Display cover plate 10 shown.

[0044] In some embodiments, the auxiliary base film 171 can be a CPI base film, a PET film, ultrathin glass, etc., as long as the auxiliary base film 171 exhibits a certain degree of plasticity. That is, as long as the auxiliary base film 171 can be shaped into a curved surface shape, and embodiments of the present disclosure do not restrict this.

[0045] In some embodiments, the fourth adhesive layer 172 can be a UV anti-adhesive layer or the like, as long as it facilitates the removal of the auxiliary film layer 17 from the injection layer 12, and embodiments of the present disclosure do not restrict this. Using the example of the fourth adhesive layer 172 being a UV anti-adhesive layer, after obtaining the injection layer 12 by injection molding, UV light can be used to irradiate the fourth adhesive layer 172, causing it to lose its adhesive strength and thus facilitating the removal of the auxiliary film layer 17 from the injection layer 12.

[0046] In some embodiments of the present disclosure, the display cover plate 10, which includes the injection layer 12 described above, further comprises an oleophobic layer 16. The oleophobic layer 16 is located on the side of the convex surface 12a of the injection layer. In this way, the oleophobic layer 16 enhances the user's tactile experience while simultaneously helping to ensure the cleanliness of the display cover plate 10. The material of the oleophobic layer 16 and the method for producing the oleophobic layer 16 may relate to relevant technologies, and embodiments of the present disclosure do not limit this.

[0047] In some embodiments, such as in Fig. As shown in Figure 10, the display cover plate 10 further comprises a hardened layer 15 located on the side of the convex surface 12a of the injection layer. In this way, the provision of the hardened layer 15 further improves the structural strength of the display cover plate 10 and reduces the occurrence of concave deformation of the display cover plate 10 under an external force. The material of the hardened layer 15 and the method for producing the hardened layer 15 may relate to relevant technologies, and embodiments of the present disclosure do not limit this.

[0048] In some embodiments, such as in Fig. As shown in Figure 11, the display cover plate 10 comprises both an oleophobic layer 16 and a hardened layer 15. The hardened layer 15 is located on the side of the convex surface 12a of the injection layer, and the oleophobic layer 16 is located on a side of the hardened layer 15 away from the injection layer 12. In this way, by providing both the hardened layer 15 and the oleophobic layer 16, not only is the tactile experience of the user improved and the cleanliness of the display field 20 ensured, but the structural strength of the display cover plate 10 is also further improved and the occurrence of concave deformation of the display cover plate 10 under an external force is reduced.

[0049] In some embodiments, the display cover plate 10 further comprises at least one first substrate 13, and the at least one first substrate 13 is stacked on a side of the injection layer 12 furthest from the antireflective layer 11. In this way, the thickness of the protective layer of the display cover plate 10 is further increased by providing the at least one first substrate 13, thereby improving the structural stability of the display cover plate 10.

[0050] In some embodiments, a first substrate 13 is typically provided to avoid a thick display device resulting from the mounting of an excessively thick display cover plate 10. As in Fig. As shown in Figure 12, the display cover plate 10 comprises a first substrate 13 which is stacked on the side of the injection layer 12 furthest from the anti-reflective layer 11.

[0051] In some embodiments, such as in Fig. As shown in Figure 12, the first substrate 13 comprises a first base film 131 and a second adhesive layer 132. The first base film 131 has a curved surface shape adapted to the curved surface region of the antireflective film 111. The first base film 131 has a convex surface and a concave surface, with the concave surface 131b of the first base film facing the injection layer 12, and the second adhesive layer 132 being located on the side of the concave surface 131b of the first base film.

[0052] In some embodiments, the film material of the first base film 131 can be identical or different from the film material of the auxiliary base film 171, and the material of the second adhesive layer 132 can be identical or different from the material of the first adhesive layer 112. Embodiments of the present disclosure do not restrict this.

[0053] The method for producing the first substrate 13 may refer to the method for producing the antireflective layer 11 described above. The methods for producing the two may be the same or different, and embodiments of the present disclosure do not restrict this. In some embodiments, the second adhesive layer 132 is first applied or bonded to one side of the first base film 131, and then the first base film 131 and the second adhesive layer 132 are placed as a whole into the mold 18 to form them into the curved surface shape, thus obtaining the curved antireflective layer 11.

[0054] In some embodiments of the present disclosure, the display cover plate 10, which comprises the first substrate 13 described above, further includes an oleophobic layer 16. The oleophobic layer 16 is located on the side of the convex surface 131a of the first base film. In this way, the oleophobic layer 16 enhances the user's tactile experience while simultaneously helping to ensure the cleanliness of the display cover plate 10. The material of the oleophobic layer 16 and the method for producing the oleophobic layer 16 may relate to relevant technologies, and embodiments of the present disclosure do not limit this.

[0055] In some embodiments, such as in Fig. As shown in Figure 13, the display cover plate 10 further comprises a hardened layer 15 located on the side of the convex surface 131a of the first base film. In this way, the provision of the hardened layer 15 further improves the structural strength of the display cover plate 10 and reduces the occurrence of concave deformation of the display cover plate 10 under an external force. The material of the hardened layer 15 and the method for producing the hardened layer 15 may relate to relevant technologies, and embodiments of the present disclosure do not limit this.

[0056] In some embodiments, such as in Fig. As shown in Figure 14, the display cover plate 10 comprises both an oleophobic layer 16 and a hardened layer 15. The hardened layer 15 is located on the side of the convex surface 131a of the first base film, and the oleophobic layer 16 is located on a side of the hardened layer 15 away from the first base film 131. In this way, by providing both the hardened layer 15 and the oleophobic layer 16, not only is the tactile experience of the user improved and the cleanliness of the display field 20 ensured, but the structural strength of the display cover plate 10 is also further improved and the occurrence of concave deformation of the display cover plate 10 under an external force is reduced.

[0057] In some embodiments, the display cover plate 10 further comprises at least one second substrate 14, and the at least one second substrate 14 is stacked between the antireflective layer 11 and the injection layer 12. In this way, by providing one or more second substrates 14, the thickness of the protective layer of the display cover plate 10 is further increased, thereby improving the structural stability of the display cover plate 10.

[0058] In some embodiments, a second substrate 14 is typically provided to avoid a thick display device resulting from the mounting of an excessively thick display cover plate 10. As in Fig. As shown in Figure 15, the display cover plate 10 comprises a second substrate 14 stacked between the anti-reflective layer 11 and the injection layer 12.

[0059] In some embodiments, such as in Fig. As shown in Figure 15, the second substrate 14 comprises a second base film 141 and a third adhesive layer 142. The second base film 141 has a curved surface shape adapted to the curved surface region of the antireflective film 111. The second base film 141 has a convex surface and a concave surface; the concave surface 141b of the second base film faces the first adhesive layer 112, and the third adhesive layer 142 is located on the side of the convex surface 141a of the second base film.

[0060] In some embodiments, the film material of the second base film 141 can be the same as or different from the film material of the auxiliary base film 171, and the material of the third adhesive layer 142 can be the same as or different from the material of the first adhesive layer 112 mentioned above. Embodiments of the present disclosure do not restrict this.

[0061] It should be noted that since the second substrate 14 and the anti-reflective layer 11 are attached by gluing, in order to avoid wrinkling and other problems at the corners of the anti-reflective layer 11 when gluing the curved second substrate 14 onto the curved anti-reflective layer 11, the second substrate 14 and the anti-reflective layer 11 can first be stacked, and then placed as a whole into the forming mold 18 to form a curved surface shape.

[0062] In some embodiments, after the second base film 141 and the antireflective layer 11 have been stacked and placed as a whole in the forming mold 18 to create a curved surface shape, the third adhesive layer 142 is formed on the convex surface 141a of the second base film. In some embodiments, the third adhesive layer 142, the second base film 141, and the antireflective layer 11 can also first be stacked sequentially and then placed as a whole in the forming mold 18 to create a curved surface shape. The embodiments described in this disclosure do not restrict this.

[0063] It should be noted that if the display cover plate 10 includes the first substrate 13 and / or the second substrate 14, the thickness of the injection layer 12 can be suitably reduced to avoid making the overall thickness of the display cover 10 too large. In some embodiments, the thickness of the injection layer 12 can be greater than or equal to 150 micrometers and less than or equal to 500 micrometers. The stiffness modulus of the injection layer 12 can also be suitably adjusted. In some embodiments, the stiffness modulus of the injection layer 12 is greater than or equal to 0.5 GPa.

[0064] Embodiments of the present disclosure also provide a method for manufacturing a display cover plate. As in Fig. As shown in Figure 16, the procedure comprises the following steps S1610 to S1640.

[0065] In step S1610 an anti-reflective film is provided, and based on the anti-reflective film an anti-reflective layer is formed, wherein at least part of the anti-reflective layer has a curved surface shape.

[0066] In step S1620, a first base film is provided, and a first substrate is formed based on the first base film, wherein at least part of the first substrate has a curved surface shape.

[0067] In step S1630, the antireflective layer and the first substrate are placed in an injection mold, with a curved surface region of the antireflective layer and a curved surface region of the first substrate facing each other. The convex surface of the first substrate is in contact with the convex part of the injection mold, and the concave surface of the antireflective layer is in contact with the concave part of the injection mold.

[0068] In step S1640, a display cover plate comprising an injection layer is obtained by performing injection molding between the concave surface of the first substrate and the convex surface of the anti-reflective layer.

[0069] According to embodiments of the present disclosure, for the display cover plate produced by the above steps, the injection layer between the anti-reflective layer and the first substrate is formed by injection molding, thereby avoiding the bonding in the associated technology between the curved anti-reflective film and the curved protective layer (glass substrate, resin substrate, etc.) which is prefabricated, reducing wrinkling, insufficient contact and gaps at the corners of the anti-reflective film, and improving the yield of the display cover plate.Furthermore, for the curved anti-reflective layer, during the formation of the injection layer by the injection molding process, the injection material can effectively compress the anti-reflective layer, and then furthermore shape the curved surface form of the anti-reflective layer with the assistance of the injection mold, in order to reduce the requirements for the size and / or shape of the curved surface form of the anti-reflective layer while ensuring the yield of the display cover plate.

[0070] In step S1610 above, specific film layers of the anti-reflective film may refer to the embodiments above, which are not repeated here.

[0071] In some embodiments, the process of forming the antireflective layer, at least part of which has a curved surface shape, using the antireflective film can be as follows. As in Fig. As shown in Figure 5, a first adhesive layer is formed on one side of the antireflective film, thus obtaining a flat antireflective layer. Hot-press forming is applied to the flat antireflective layer to shape the antireflective layer, resulting in a curved antireflective layer that includes a curved surface area (at least part of the antireflective layer has a curved surface shape), and the first adhesive layer is located on the side of the convex surface of the antireflective layer.

[0072] The specific details of the first adhesive layer can refer to the embodiments described above, and the first adhesive layer can be formed on one side of the antireflective film by gluing or application. For the flat antireflective layer, in addition to hot-pressure forming, high-pressure forming, etc., can also be used, which are not repeated in this disclosure. When the flat antireflective layer is formed using hot-pressure forming, one side of the first adhesive layer, furthest from the antireflective film, has the release paper to prevent the first adhesive layer from adhering to the forming mold during hot-pressure forming and interfering with the subsequent demolding.

[0073] In some embodiments, hot-pressure forming is applied to the antireflective film, thus obtaining a curved antireflective film that includes a curved surface area (at least part of the antireflective film has a curved surface shape). Then, the first adhesive layer is formed on the side of the convex surface of the antireflective film to obtain the curved antireflective layer that includes a curved surface area (at least part of the antireflective layer has a curved surface shape).

[0074] In some embodiments, in addition to hot-press forming, high-pressure forming, etc., can also be used for the flat antireflective film. The specific details of the first adhesive layer can refer to the embodiments mentioned above, which are not repeated in the present disclosure. Compared to the embodiments mentioned above, since hot-press forming is applied directly to the antireflective film to form it, the forming effect of the antireflective layer is not affected by the presence of the release paper. After the forming of the antireflective film is complete, the curved antireflective film is obtained, and the first adhesive layer can be formed by applying it to the convex surface of the antireflective film.

[0075] In some embodiments, a first adhesive layer is formed on one side of the antireflective film, and a second base film and a third adhesive layer are successively formed on a side of the first adhesive layer furthest from the antireflective film to obtain a flat antireflective layer. Hot stamping is then applied to the flat antireflective layer, and the curved antireflective layer, which includes a curved surface area (at least part of the antireflective layer has a curved surface shape), is obtained.

[0076] In some embodiments, the first adhesive layer, the third adhesive layer, and the second base film may refer to the embodiments described above, which are not repeated in the present disclosure. The provision of the second base film further increases the thickness of the protective layer of the display cover plate, thereby improving the structural stability of the display cover plate.

[0077] Based on the embodiments described above, the third adhesive layer can be formed on the convex surface side of the first base film after the antireflective film, the first adhesive layer, and the first base film have been stacked and hot-press forming has been applied. Alternatively, the third adhesive layer can first be formed on the side of the first base film furthest from the first adhesive layer and then formed by hot-press forming. The embodiments described in this disclosure do not restrict this.

[0078] In step S1620 above, specific film layers of the first base film may refer to the embodiments described above, which are not repeated here.

[0079] In some embodiments, the process of forming the first substrate, at least part of which has a curved surface shape, using the first base film can be as follows. As in Fig. As shown in Figure 17, a second adhesive layer is formed on one side of the first base film, thus obtaining a first substrate. Hot-press molding is applied to the first substrate, which is curved and includes a curved surface area (at least part of the first substrate has a curved surface shape), as shown in Figure 17. Fig. 18 shown, will be received.

[0080] The specific details of the second adhesive layer can refer to the embodiments described above, and the second adhesive layer can be formed on one side of the first base film by gluing or application. For the flat first substrate, in addition to hot-pressure demolding, high-pressure demolding, etc., can also be used, which are not repeated in this disclosure. When the flat first substrate is demolded using hot-pressure demolding, one side of the second adhesive layer, furthest from the first base film, has the release paper to prevent the second adhesive layer from adhering to the demolding mold during hot-pressure demolding and interfering with the subsequent demolding.

[0081] In some embodiments, hot-pressure forming is applied to the first base film, thus obtaining a curved first base film that includes a curved surface region (at least part of the first base film has a curved surface shape). Then, the first adhesive layer is formed on the side of the concave surface of the first base film to obtain the curved first substrate that includes a curved surface region (at least part of the first substrate has a curved surface shape).

[0082] In some embodiments, in addition to hot-pressure forming, high-pressure forming, etc., can also be used for the flat first base film. The specific details of the second adhesive layer can refer to the embodiments mentioned above, which are not repeated in the present disclosure. Compared to the embodiments mentioned above, since hot-pressure forming is applied directly to the first base film to form it, the forming effect of the first base film is not affected by the presence of the release paper. After the forming of the first base film is complete, the curved first base film is obtained, and the second adhesive layer can be formed by application to the concave surface of the first base film.

[0083] In the above step S1630, as in Fig. As shown in Figure 19, the convex surface of the first substrate is in contact with the convex shape of the injection mold, and the concave surface of the anti-reflective layer is in contact with the concave shape of the injection mold to form a space for receiving the injection layer between the concave surface of the first substrate and the convex surface of the anti-reflective layer.

[0084] The injection material of the injection layer involved in step S1640 may refer to the embodiments above, which are not repeated here.

[0085] When forming the injection layer by injection molding between the concave surface of the first substrate and the convex surface of the anti-reflective layer, the injection layer can overflow from the injection hole of the injection mold. As in Fig. As shown in Figure 20, an edge of the injection layer will inevitably protrude from an edge of the antireflective layer. In some embodiments, the method further comprises, after the injection layer has been obtained in step S1640, removing a protruding portion of an edge of the injection layer at an edge of the display cover plate after the display cover plate containing the injection layer has been removed from the injection mold. In some embodiments, processes such as polishing, laser cutting, etc., are used to remove the protruding portion of the edge of the injection layer.

[0086] In some embodiments, after obtaining the injection layer by injection molding in step S1640, in order to obtain a light and thin display cover plate while ensuring that the injection layer has a certain structural strength to meet the structural strength requirements for the display cover plate, the first substrate can be peeled off to obtain a display cover plate comprising only the anti-reflective film and the injection layer.

[0087] To facilitate peeling off the first substrate, the second adhesive layer contained in the first substrate may relate to the fourth adhesive layer described in the embodiments mentioned above, i.e., as long as it facilitates peeling off the first substrate from the injection layer. Embodiments of the present disclosure do not restrict this.

[0088] In some embodiments, after injection molding between the concave surface of the first substrate and the convex surface of the antireflective layer, a hardened layer and / or an oleophobic layer can be formed on the convex surface side of the first substrate. The hardened layer further improves the structural strength of the display cover plate and reduces the occurrence of concave deformation under external force. The oleophobic layer enhances the user's tactile experience while ensuring the cleanliness of the display cover plate.

[0089] It should be noted that if the display cover plate includes both the hardened layer and the oleophobic layer, the hardened layer is located on the side closest to the first substrate; that is, after the injection layer has been obtained in step S1640, the hardened layer and the oleophobic layer are formed successively on the side of the convex surface of the first substrate.

[0090] In some embodiments, after the first substrate has been peeled away from the injection layer, a hardened layer and / or an oleophobic layer can be formed on the convex surface of the injection layer. Providing the hardened layer can further improve the structural strength of the display cover plate and reduce the occurrence of concave deformation of the display cover plate under external force. Providing the oleophobic layer can improve the user's tactile experience while ensuring the cleanliness of the display cover plate.If the display cover plate includes both the hardened layer and the oleophobic layer, the hardened layer is located on the side closest to the injection layer; that is, after the injection layer has been obtained in step S1640, the first substrate is peeled off the injection layer, and then the hardened layer and the oleophobic layer are successively formed on the side of the convex surface of the injection layer.

[0091] It should be noted that, although various steps of the process for manufacturing the display cover plate are described in the drawings in a specific order in the present disclosure, this does not require or imply that these steps must be carried out in this specific order, or that all the steps shown must be carried out to achieve the desired result. Additionally or alternatively, some steps may be omitted, several steps may be combined into one step for execution, and / or one step may be divided into several steps for execution.

[0092] Embodiments of the present disclosure also provide a display module 100. As in Fig. As shown in Figure 21, the display module 100 comprises a display panel 20 and the display cover plate module 10 described in the embodiments above. The display panel 20 is located on the side of the concave surface of the display cover plate 10.

[0093] In some embodiments of the present disclosure, according to the display cover plate 10 described above, the display module 100, which includes the display cover plate 10, can avoid the bonding in the associated technology between the curved anti-reflective film 111 and the curved protective layer (glass substrate, resin substrate, etc.) that is prefabricated, thereby reducing wrinkling, insufficient contact and gaps at the corners of the anti-reflective film 111, which contributes to improving the display effect and the service life of the display module 100.

[0094] In some embodiments, such as in Fig. 21 and Fig. As shown in Figure 22, the concave surface of the display cover plate 10 has a flat surface area 101 and a curved surface area 102, and the display panel 20 comprises a flat surface panel 201 and a curved surface panel 202. The flat surface panel 201 is bonded to the flat surface area 101, and the curved surface panel 202 is bonded to the curved surface area 102. In this way, by adapting the structure of the display panel 20 (which comprises both the flat surface panel 201 and the curved surface panel 202), the bonding of the display panel 20 to the concave surface of the curved display cover plate 10 is facilitated, thereby improving the bonding effect of the display panel 20 while ensuring the display function of the display module 100.

[0095] In some embodiments, such as in Fig. As shown in Figure 22, the curve surface table 202 is designed as a ring-shaped structure, the plane surface table 201 is located in the inner ring of the curve surface table 202, and a gap is formed between the plane surface table 201 and the curve surface table 202.

[0102] In step S2360, a display module comprising an injection molding layer is obtained by performing injection molding between the convex surface of the anti-reflective layer and the concave surface of the first substrate.

[0103] In some embodiments of the present disclosure, the bonding in the associated technology between the curved anti-reflective film and the curved protective layer, which is pre-fabricated, can be avoided in the manufacture of the display module, thereby reducing wrinkling, insufficient contact and gaps at the corners of the anti-reflective film, which contributes to improving the display effect and the lifetime of the display module.
