[0034] The scheme of the embodiment of the present application is described in detail below in conjunction with the drawings of the specification.

[0035] In the following description, for the purpose of explanation rather than limitation, specific details such as specific system structures, interfaces, and technologies are provided to facilitate a thorough understanding of the present application.

[0036] The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the objects associated before and after are in an "or" relationship. In addition, "many" in this article means two or more than two. In addition, the term "at least one" in this article means any combination of at least two of any one or more of a plurality of, for example, including at least one of A, B, and C, can mean including any one or more elements selected from the set consisting of A, B, and C.

[0037] See also Figure 1 , Figure 1 1 is a schematic diagram of the structure of an embodiment of the display module of the present application. The display module 100 includes: a screen body 110 and a cover plate 120. The screen body 110 includes a display area 111 and a non-display area 112 arranged outside the display area 111. The cover plate 120 is arranged on the light emitting surface side of the screen body 110, and includes a plurality of cover plate parts 121 spliced ​​together.

[0038] The display area 111 of the screen body 110 is used to display the picture, and usually includes structures such as light-emitting elements and pixel driving circuits. The non-display area 112 of the screen body 110 does not display the picture, and usually includes structures such as peripheral circuits. The screen body 110 can specifically include film layers such as a substrate, an array layer, and a light-emitting layer that are stacked in sequence.

[0039] The cover plate 120 is used to protect the screen body 110 and is attached to the screen body 110. In this embodiment, the cover plate 120 includes a plurality of cover plate portions 121, the plurality of cover plate portions 121 are independent of each other, and the plurality of cover plate portions 121 can be made of the same material.

[0040] In one embodiment, see Figure 2 , Figure 2 1 is a flow chart of an embodiment of a method for preparing a display module 100 of the present application. Specifically, the method may include the following steps:

[0041] Step S210 : sequentially attaching a plurality of cover plate portions 121 to one side of the light emitting surface of the screen body 110 .

[0042] The orthographic projections of the plurality of cover plate portions 121 on the screen body 110 do not overlap.

[0043] Specifically, since the cover plate 120 includes a plurality of independent cover plate portions 121 , during attachment, the plurality of cover plate portions 121 may be attached to the light emitting surface side of the screen body 110 in sequence.

[0044] In the prior art, the cover plate 120 is usually an integrated structure. If there is a deviation during attachment, the already attached cover plate 120 needs to be removed and reattached. This process can easily cause damage to the cover plate 120 and is cumbersome.

[0045] However, in the present application, if the attachment position of one cover plate portion 121 deviates during attachment, the position and size of the unattached cover plate portion 121 can be adjusted to compensate for the deviation, so the present application can reduce the requirements for the attachment accuracy of the cover plate 120. At the same time, during the attachment process, the present application can also adjust the size of the unattached cover plate portion 121 to ensure that the size of the final cover plate 120 is the same as the size of the screen body 110, so as to achieve a narrow frame of the display module 100.

[0046] In one embodiment, the materials of the multiple cover plate parts 121 are the same to ensure that the light transmittance of each position of the cover plate 120 is consistent, thereby ensuring the display effect of the display module 100. For example, in one embodiment, the materials of the multiple cover plate parts 121 all include glass. Of course, in other embodiments, the materials of the multiple cover plate parts 121 can also be different.

[0047] In one embodiment, the plurality of cover portions 121 are all transparent cover portions, and the display module 100 further includes a shading layer 160, which is disposed between the screen body 110 and the cover plate 120, wherein the shading layer 160 has an orthographic projection on the screen body 110 covering the non-display area 112, so that the shading layer 160 can be used to cover the peripheral circuits and other structures in the non-display area 112, so that the non-display area of ​​the display module 100 is the non-display area 112 of the screen body 110, thereby achieving a narrow frame of the display module 100.

[0048] In one embodiment, during the preparation process, Figure 3 as well as Figure 4 Before the above step S210 , the method further includes: performing a blackening treatment on the non-display area 112 of the screen body 110 on the light emitting surface side of the screen body 110 , so as to form the above-mentioned light shielding layer 160 .

[0049] Specifically, before attaching the cover plate 120, the non-display area 112 of the screen body 110 is first blackened to form a light shielding layer 160 covering the non-display area 112, so that the multiple cover plate parts 121 attached subsequently can all be transparent cover plate parts. The material of the light shielding layer 160 includes at least one of a black matrix and ink.

[0050] In one embodiment, a black light shielding material may be applied to the entire light emitting surface of the screen body 110 to obtain a light shielding layer 160, and then the light shielding layer 160 is patterned to expose the screen body 110 located in the display area 111. The black light shielding material may include at least one of a black matrix and ink.

[0051] After the screen body is blackened, the screen body 110 can be processed by normal display module process, for example, a filter layer 130 is set on the screen body 110 to prevent the parallel light generated by the screen body 110 from being captured by the naked eye. The filter layer 130 can be set as a polarizer. Therefore, in this embodiment, the light shielding layer 160 is located between the screen body 110 and the filter layer 130. For details, please refer to Figure 1 .

[0052] In addition, a protective film may be attached to the screen body 110 , or the screen body 110 may be packaged using a COP (Chip On Pi) packaging process.

[0053] Combination Figures 1 to 5 In one embodiment, the plurality of cover plate portions 121 include a first cover plate portion 1211 and at least one second cover plate portion 1212 disposed on the periphery of the first cover plate portion 1211, wherein the orthographic projection of the first cover plate portion 1211 on the screen body 110 covers the screen body in the display area 111, and the orthographic projection of the second cover plate portion 1212 on the screen body 110 is located in the non-display area 112. In the preparation process, step S210 specifically includes: attaching the first cover plate portion 1211 to one side of the light emitting surface of the screen body 110, and then attaching at least one second cover plate portion 1212 surrounding the first cover plate portion 1211 to one side of the light emitting surface of the screen body 110.

[0054] Specifically, the first cover portion 1211 is the main structure, and its orthographic projection on the screen body 110 covers the screen body 110 located in the display area 111, but does not cover the entire screen body 110. That is to say, the first cover portion 1211 is retracted relative to the screen body 110, so that the edge of the first cover portion 1211 is at a safe distance from the display area 111. At the same time, the edges of the first cover portion 1211 are all located in the non-display area 112 to avoid affecting the normal display of the screen body 110.

[0055] The number of the second cover plate portion 1212 can be one or more. When attaching, the first cover plate portion 1211 is attached first, and then the second cover plate portion 1212 is attached.

[0056] See also Figure 3In one embodiment, the non-display area 112 includes a first non-display sub-area 1121 and a second non-display sub-area 1122 arranged on opposite sides of the display area 111 along a first direction X, and a third non-display sub-area 1123 and a fourth non-display sub-area 1124 arranged on opposite sides of the display area 111 along a second direction Y, wherein the first direction X intersects with the second direction Y. Specifically, in this embodiment, the first direction X is the up-down direction of the screen body 110, and the second direction Y is the left-right direction of the screen body 110. In other embodiments, the first direction X and the second direction Y may be directions intersecting at other angles.

[0057] Combination Figure 5 When the first cover plate portion 1211 is attached, the orthographic projection of the first cover plate portion 1211 on the screen body 110 covers the screen body 110 in the display area 111 and the second non-display sub-area 1122. At this time, there are still parts of the screen body 110 not covered at the upper left and right edges of the first cover plate portion 1211, so the second cover plate portion 1212 can be attached next.

[0058] In one embodiment, three second cover portions 1212 are provided, and the three second cover portions 1212 are respectively provided on the first non-display sub-area 1121, the third non-display sub-area 1123 and the fourth non-display sub-area 1124, and the orthographic projections of the three second cover portions 1212 on the screen body 110 are located in the non-display area 112, so that the total area of ​​the first cover portion 1211 and the second cover portion 1212 is close to the area of ​​the screen body 110.

[0059] In order to avoid inconsistent light transmittance between the first cover plate portion 1211 and the second cover plate portion 1212 after bonding, the materials of the bonded first cover plate portion 1211 and the second cover plate portion 1212 are the same, and the first cover plate portion 1211 and the second cover plate portion 1212 may be different in size but also have the same thickness. Specifically, the materials of the first cover plate portion 1211 and the second cover plate portion 1212 both include glass, for example, a hard transparent glass strip.

[0060] Combination Figure 1 During the bonding process, in order to enable the cover plate 120 to be tightly attached to the screen body 110 or the filter layer 130, an adhesive layer 140 may be provided in the display module 100, and the adhesive layer 140 may be provided on a side of the cover plate 120 close to the screen body 110, so that the cover plate 120 is tightly adhered to the screen body 110 through the adhesive layer 140.

[0061] In one embodiment, the bonding layer 140 may be made of OCA (Optically Clear Adhesive) glue, and the OCA glue is applied to the side of the first cover portion 1211 and the second cover portion 1212 close to the screen body 110, so that the first cover portion 1211 and the second cover portion 1212 can be tightly adhered to the screen body 110, and at the same time, the light output rate of the screen body 110 can be guaranteed as much as possible.

[0062] Continue reading Figure 1 In one embodiment, the display module 100 further includes: a protective glue 122, the outer edge of the protective glue 122 being projected on the screen body 110 is located outside the outer edge of the screen body 110 or coincides with the outer edge of the screen body 110. Specifically, in order to prevent the plurality of cover plate portions 121 from not being able to completely cover the screen body 110, the protective glue 122 is preferably disposed on the outer edge of the screen body 110. Figure 2 as well as Figure 6 , during the preparation process, after step S110, the following steps are further included:

[0063] Step S220: coating the protective glue 122 on the peripheries of the plurality of cover plate parts.

[0064] The total orthographic projection of the plurality of cover plate portions 121 and the protective adhesive 122 on the screen body 110 covers the screen body 110 .

[0065] Specifically, the protective glue 122 is applied to cover the area of ​​the screen body 110 that is not covered by the multiple cover plate parts 121 to protect the edge of the screen body 110, so that the total orthographic projection of the multiple cover plate parts 121 and the protective glue 122 on the screen body 110 covers the screen body 110. The protective glue 122 can be the same color as the multiple cover plate parts 121, for example, transparent; or the protective glue 122 can be the same color as the light shielding layer on the screen body 110, for example, black. Therefore, the color of the protective glue 122 is not specifically limited here.

[0066] In the above scheme, considering the accuracy of the attachment equipment and the tolerance of the materials, and the fact that the multiple cover plate parts 121 are attached to the screen body 110 step by step, at this time, there are still some areas of the screen body 110 that are not covered by the cover plate parts 121. And after the multiple cover plate parts 121 are attached step by step, the width of the area on the screen body 110 that is still not covered is very small, and it is no longer suitable to be attached and covered by the cover plate parts 121. Therefore, the protective glue 122 can be used to coat and cover the periphery of the spliced ​​multiple cover plate parts 121 and the area of ​​the screen body 110 that is still not covered, so that the total orthographic projection of the multiple cover plate parts 121 and the protective glue 122 on the screen body 110 can completely cover the screen body 110.

[0067] The material of the protective glue 122 includes shadowless glue, for example, UV (Ultraviolet Rays) glue, etc., which is not specifically limited here.

[0068] In order to better understand the solution of this application, Figures 4 to 6 The preparation method of the display module 100 is introduced as follows:

[0069] First, the non-display area 112 of the screen body 110 is blackened to obtain the light shielding layer 160. The process may specifically include: coating the entire light emitting surface of the screen body 110 with a black light shielding material to obtain the entire light shielding layer 160, and then patterning the light shielding layer 160 to expose the screen body 110 located in the display area 111.

[0070] Afterwards, the first cover plate portion 1211 is attached to the screen body 110 in an inwardly retracted manner, so that the orthographic projection of the first cover plate portion 1211 on the screen body 110 covers the screen body 110 located in the display area 111 and the second non-display sub-area 1122. At this time, there is still a part of the screen body 110 that is not covered at the upper left and right edges of the first cover plate portion 1211. Therefore, three second cover plate portions 1212 are provided to be attached to the upper left and right edges of the first cover plate portion 1211 to supplement the coverage of the first cover plate portion 1211. After the first cover portion 1211 and the second cover portion 1212 are attached, if there are still some areas at the edge of the screen body 110 that are not covered by the cover portion 121, UV glue is applied to the edge of the cover portion 121 to obtain the protective glue 122, so that the total orthographic projection of the multiple cover portions 121 and the protective glue 122 on the screen body 110 covers the screen body 110, thereby achieving the purpose of the frame of the display module 100 being the frame of the screen body 110, thereby realizing the narrow frame of the display module 100.

[0071] It should be noted that between the blackening of the non-display area of ​​the screen body 110 and the attachment of the first cover plate portion 1211, conventional processes such as attaching polarizers, supporting film layers, bonding flexible circuit boards, chips, etc. can also be carried out. These conventional processes are all existing technologies and will not be introduced in detail here.
