[0002] Currently, in the field of display technology, existing display modules require a filling support structure to support the cover plate during the packaging process. However, the filling support structure in existing display modules is easily damaged during the packaging process, which seriously affects the display effect and appearance of the existing display modules.

[0003] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in this field. Summary of the Invention

[0004] The present disclosure aims to provide a display module and a display device with better display effect and better appearance.

[0005] In one aspect, the present disclosure provides a display module, wherein the display module has a display area and a non-display area located outside the display area, and the display module includes:

[0006] Driver backplane;

[0007] a cover plate, spaced apart from the driving back plate;

[0008] a light-emitting structure, disposed between the driving back plate and the cover plate and located in the display area;

[0009] A support stop structure, supported between the driving back plate and the cover plate, and arranged around the display area;

[0010] A filling support structure, filling the space enclosed by the driving back plate, the cover plate and the support stop structure, and covering the light-emitting structure;

[0011] An edge sealing structure is arranged around the support stop structure, and the edge sealing structure is sealed between the driving back plate and the cover plate.

[0012] In an exemplary embodiment of the present disclosure, a first gap is defined between the edge sealing structure and the support and stop structure; and the display module further comprises:

[0013] The first reinforcing structure is located in the first interval and supported between the driving back plate and the cover plate.

[0014] In an exemplary embodiment of the present disclosure, the support stop structure and the edge sealing structure are both polygonal ring structures, and the vertex in the support stop structure is a first vertex, and the vertex in the edge sealing structure is a second vertex;

[0015] The first reinforcement structure is located between a region where the first vertex is located and a region where the second vertex is located.

[0016] In an exemplary embodiment of the present disclosure, the first reinforcing structure has a third vertex and a first extension portion and a second extension portion located on both sides of the third vertex, and the extension directions of the first extension portion and the second extension portion are respectively the same as the extension directions of the partial supporting stop structures located on both sides of the first vertex.

[0017] In an exemplary embodiment of the present disclosure, the first vertex, the second vertex and the third vertex are collinear.

[0018] In an exemplary embodiment of the present disclosure, a second interval is provided between the support and stop structure and the light-emitting structure; and the display module further comprises:

[0019] The second reinforcing structure is located in the second interval and supported between the driving back plate and the cover plate.

[0020] In an exemplary embodiment of the present disclosure, the support and stop structure is a polygonal ring structure, and the vertex in the support and stop structure is a first vertex;

[0021] The second reinforcement structure is located between the area where the first vertex is located and the light-emitting structure.

[0022] In an exemplary embodiment of the present disclosure, a minimum distance between the second reinforcement structure and the light emitting structure is greater than or equal to 5 micrometers.

[0023] In an exemplary embodiment of the present disclosure, the support and stop structure includes:

[0024] At least two sub-support structures are nested with each other, and a third interval exists between any two adjacent sub-support structures.

[0025] Another aspect of the present disclosure provides a display device, which includes the display module described above.

[0026] The technical solution provided by the present disclosure can achieve the following beneficial effects:

[0027] The present disclosure provides a display module, including a driving back plate, a cover plate, a light-emitting structure, a support stop structure, a filling support structure and an edge sealing structure. The support stop structure is supported between the driving back plate and the cover plate and is arranged around the display area. The filling support structure fills the space enclosed by the driving back plate, the cover plate and the support stop structure, and covers the light-emitting structure. It can be seen that by setting the support stop structure, the material forming the filling support structure can be stopped when the filling support structure is filled, thereby avoiding the problem of overflow of the material forming the filling support structure and ensuring the shape and support strength of the finally formed filling support structure.

[0028] Furthermore, using only the filling support structure for support in the display area ensures display uniformity, prevents other support structures from affecting the display in the display area, and prevents other support structures from being squeezed and deformed or collapsed, resulting in poor appearance and display quality in the display area. Furthermore, using the support stop structure for support in the non-display area further increases support strength, ensures the flatness of the cover plate, and improves display quality.

[0029] The edge sealing structure surrounds the support stop structure and seals between the driver backplate and the cover plate. The support stop structure can be positioned between the filling support structure and the edge sealing structure, increasing the distance between them. This prevents the filling support structure from being sintered during sintering of the edge sealing structure, thus preventing deformation of the filling support structure. This further ensures the support strength of the support stop structure and the display quality and appearance of the display module.

[0030] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0042] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express open-ended inclusion and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first" and "second" etc. are used only as labels and are not intended to limit the quantity of their objects.

[0043] The present disclosure provides a display device, which may be a mobile phone, a tablet computer, a television, a car display, etc. The display device may include a display module, which may be used to display images.

[0044] like Figures 1 to 6 As shown, the display module may have a display area 1a and a non-display area 1b located outside the display area 1a. The display area 1a may be used to display images, and the non-display area 1b is used for circuit routing, etc.

[0045] like Figure 1 and Figure 2 As shown, the display module may include: a driving backplane 2, a cover plate 3, and a light-emitting structure 4. The cover plate 3 may be arranged relative to the driving backplane 2, and the light-emitting structure 4 may be arranged between the driving backplane 2 and the cover plate 3, and located in the display area 1a. The light-emitting structure 4 may be electrically connected to the driving backplane 2, and the driving backplane 2 may provide a driving signal to drive the light-emitting structure 4 to emit light. The cover plate 3 may be used to protect the structures located below the cover plate 3, such as the light-emitting structure 4 and the driving backplane 2. The material of the cover plate 3 may be glass, but is not limited thereto. The material of the cover plate 3 may also be a resin material, etc.

[0046] The light-emitting structure 4 may be an OLED pixel unit 41. The light-emitting structure 4 may include multiple pixel units 41, which may be arranged in an array. The multiple pixel units 41 may include red pixels, green pixels, and blue pixels. The present disclosure does not limit the arrangement of the red pixels, green pixels, and blue pixels, and the arrangement may be selected and configured according to actual circumstances, all of which are within the scope of protection of the present disclosure.

[0047] The display module may further include a support and stop structure 5 and a filling support structure 6. The support and stop structure 5 may be supported between the driver backplate 2 and the cover plate 3 and disposed around the display area 1a, such that the support and stop structure 5, the driver backplate 2, and the cover plate 3 together form a receiving space. The support and stop structure 5 may be made of a transparent photoresist, which can improve the molding efficiency of the support and stop structure 5 and ensure the supporting strength of the support and stop structure 5. However, the present invention is not limited to this and the support and stop structure 5 may also be made of other transparent materials.

[0048] The support and stop structure 5 may be a polygonal ring structure, for example, a rectangular ring structure, a square ring structure, a triangular ring structure, a pentagonal ring structure, a hexagonal ring structure, etc. However, the support and stop structure 5 is not limited thereto and may also be a circular ring structure.

[0049] The filling support structure 6 can fill the space enclosed by the driver backplane 2, cover plate 3, and support stop structure 5, and cover the light-emitting structure 4. Thus, this embodiment utilizes only the filling support structure 6 for support in the display area 1a, ensuring display uniformity and preventing other support structures from affecting the display in the display area 1a. It also prevents other support structures from being squeezed and deformed or collapsed, resulting in poor appearance and display quality in the display area 1a. Furthermore, utilizing the support stop structure 5 for support in the non-display area 1b further increases support strength, further ensures the flatness of the cover plate 3, and further enhances the display quality.

[0050] At the same time, this embodiment can stop the material forming the filling support structure 6 when the filling support structure 6 is filled by setting the support stop structure 5, thereby avoiding the problem of overflow of the material forming the filling support structure 6 and ensuring the shape and support strength of the final filling support structure 6.

[0051] The thickness of the support and stop structure 5 can be 2 μm to 5 μm, for example, 2 μm, 3 μm, 4 μm, 5 μm, etc. The thickness of the filling support structure 6 can be the same as that of the support and stop structure 5, that is, the thickness of the filling support structure 6 can also be 2 μm to 5 μm, for example, 2 μm, 3 μm, 4 μm, 5 μm, etc.

[0052] In some embodiments, a second spacing S2 may be provided between the support and stop structure 5 and the light-emitting structure 4. Specifically, it is understood that the second spacing S2 may be the spacing between the edge of the support and stop structure 5 closest to the light-emitting structure 4 and a pixel unit 41 in the light-emitting structure 4 closest to the support and stop structure 5. Providing the second spacing S2 prevents the support and stop structure 5 from affecting the light emitted by the light-emitting structure 4, thereby preventing color shift during display by the display module.

[0053] The second interval S2 may be greater than or equal to 5 μm to ensure that there is a sufficient interval between the support and stop structure 5 and the light emitting structure 4 , and to ensure that the display module does not have a color shift problem during display.

[0054] The second interval S2 can be less than or equal to 400 μm. For example, the second interval S2 can be 5 μm, 10 μm, 50 μm, 100 μm, 150 μm, 200 μm, 250 μm, 300 μm, 350 μm, 400 μm, etc. This configuration can avoid the problem of the non-display area 1b of the display module being too large due to the second interval S2 being too large, and can increase the proportion of the display area 1a, thereby improving the user's viewing experience.

[0055] The display module may also include an edge sealing structure 7. This structure can be positioned around the support and stop structure 5 and seal between the driver backplane 2 and the cover plate 3. This structure blocks moisture and impurities from the external environment, preventing them from entering the display module and potentially impacting the device structure within. This improves the stability and lifespan of the display module. Furthermore, the edge sealing structure 7 provides support for the cover plate 3, further ensuring its flatness and enhancing the display quality.

[0056] In this embodiment, when the edge sealing structure 7 is arranged around the support stop structure 5, the support stop structure 5 can be located between the filling support structure 6 and the edge sealing structure 7, thereby increasing the distance between the edge sealing structure 7 and the filling support structure 6. In this way, when the edge sealing structure 7 is sintered, the filling support structure 6 will not be sintered, and the filling support structure 6 can be avoided from deformation and deformation, further ensuring the supporting strength of the support stop structure 5, and further ensuring the display effect and appearance effect of the display module.

[0057] The edge sealing structure 7 may be a polygonal ring structure, for example, a rectangular ring structure, a square ring structure, a triangular ring structure, a pentagonal ring structure, a hexagonal ring structure, etc. However, the invention is not limited thereto, and the edge sealing structure 7 may also be a circular ring structure.

[0058] The width W2 of the edge seal structure 7 can be greater than or equal to 200 μm and less than or equal to 500 μm, for example, 200 μm, 250 μm, 300 μm, 350 μm, 400 μm, 450 μm, 500 μm, etc. This configuration ensures that the edge seal structure 7 has a sufficient width W2, thereby providing good sealing, isolation, and support capabilities. This also avoids the problem of excessive width W2 of the edge seal structure 7 resulting in an oversized non-display area 1b, thereby increasing the proportion of the display area 1a and improving the user's viewing experience.

[0059] In some embodiments, the driving back plate 2 may have a groove, and the end of the edge sealing structure 7 away from the cover plate 3 may be located in the groove, thereby improving the sealing effect of the edge sealing structure 7 .

[0060] In some embodiments, a first gap S1 may be provided between the edge sealing structure 7 and the support stop structure 5 to further increase the gap between the edge sealing structure 7 and the filling support structure 6. When the edge sealing structure 7 is sintered, the filling support structure 6 can be further prevented from being sintered, thereby further preventing the filling support structure 6 from being deformed and deformed, further ensuring the support strength of the support stop structure 5, and further ensuring the display effect and appearance of the display module.

[0061] The first interval S1 can be greater than or equal to 150 μm and less than or equal to 500 μm. For example, the second interval S2 can be 150 μm, 200 μm, 250 μm, 300 μm, 350 μm, 400 μm, 450 μm, 500 μm, etc. This arrangement ensures sufficient spacing between the edge sealing structure 7 and the support and stop structure 5. Furthermore, it can also avoid the problem of the non-display area 1b being too large due to the first interval S1 being too large.

[0062] In some embodiments, the width W1 of the support stop structure 5 can be greater than or equal to 100 μm and less than or equal to 500 μm, for example: 100 μm, 150 μm, 200 μm, 250 μm, 300 μm, 350 μm, 400 μm, 450 μm, 500 μm, etc. This configuration can ensure that the support stop structure 5 has a sufficient width W1 so that it has better supporting capacity. In addition, the spacing between the edge sealing structure 7 and the filling support structure 6 can be further increased. At the same time, it can also avoid the problem of the non-display area 1b being too large due to the width W1 of the support stop structure 5 being too large, and the proportion of the display area 1a can be increased, thereby improving the user's viewing experience.

[0063] like Figure 3 and Figure 4 As shown, the support stop structure 5 may include: at least two sub-support structures 51. For example: the support stop structure 5 may include: two, three, four sub-support structures 51, etc. At least two sub-support structures 51 may be nested with each other, and there is a third interval S3 between any two adjacent sub-support structures 51. It should be noted that the width of the support stop structure 5 described above is the sum of the width W3 of each sub-support structure 51 and each third interval S3. With such an arrangement, when the width W1 of the support stop structure 5 is constant, the material for manufacturing the support stop structure 5 can be saved, thereby saving the cost of manufacturing the display module.

[0064] In some embodiments, as Figure 2 As shown, the upper surface of the edge sealing structure 7, the upper surface of the support stop structure 5 and the upper surface of the filling support structure 6 can be flush to ensure the flatness of the cover plate 3 and the display effect of the display module.

[0065] In some embodiments of the present disclosure, Figure 5 and Figure 6 As shown, the display module further includes a first reinforcement structure 8. The first reinforcement structure 8 can be located within the first gap S1 and supported between the drive backplane 2 and the cover plate 3. By providing the first reinforcement structure 8, the cover plate 3 can be supported at the first gap S1. This arrangement prevents bending of the cover plate 3 caused by unevenness between the upper surface of the edge sealing structure 7 and the upper surface of the support stop structure 5, thereby avoiding the problem of Newton rings in the display module and improving the display quality of the display module.

[0066] When the support and stop structure 5 and the edge sealing structure 7 are both polygonal ring structures, the vertex in the support and stop structure 5 is the first vertex 52 , and the vertex in the edge sealing structure 7 is the second vertex 71 .

[0067] It should be noted that the vertex in the support and stop structure 5 is the intersection of any two adjacent sides in the support and stop structure 5 . The vertex in the edge sealing structure 7 is the intersection of any two adjacent sides in the edge sealing structure 7 .

[0068] The first reinforcing structure 8 can be located between the area where the first vertex 52 is located and the area where the second vertex 71 is located. The area where the first vertex 52 is located is the area located near the first vertex 52. The area where the second vertex 71 is located is the area located near the second vertex 71. Since the upper surface of the area where the second vertex 71 of the edge sealing structure 7 is located and the upper surface of the area where the first vertex 52 of the support stop structure 5 is located are prone to unevenness, the first reinforcing structure 8 is set between the area where the first vertex 52 is located and the area where the second vertex 71 is located, which can further solve the problem of Newton rings appearing on the display module, thereby improving the display effect of the display module.

[0069] The first reinforcement structure 8 may include a third vertex 81 and first and second extensions 82 and 83 located on either side of the third vertex 81. The first and second extensions 82 and 83 may extend in the same direction as the portions of the support stop structure 5 located on either side of the first vertex 52. This arrangement further improves the flatness of the cover plate 3 and eliminates the problem of Newton rings caused by unevenness of the cover plate 3.

[0070] Furthermore, the first vertex 52 of the support stop structure 5, the second vertex 71 of the edge sealing structure 7 and the third vertex 81 of the first reinforcement structure 8 can be collinear, thereby ensuring that the first reinforcement structure 8 can be supported at the part between the first vertex 52 and the second vertex 71 where the cover plate 3 is most likely to be uneven, thereby further eliminating the problem of Newton rings caused by the unevenness of the cover plate 3.

[0071] like Figure 5 and Figure 6 As shown, the shape of the first reinforcement structure 8 may be similar to a semicircle, but is not limited thereto. The edge shape of the first reinforcement structure 8 may also be similar to a triangle, etc.

[0072] The spacing S4 between the first reinforcing structure 8 and the edge sealing structure 7 can be greater than or equal to 150 μm and less than or equal to 500 μm, for example, 150 μm, 200 μm, 250 μm, 300 μm, 350 μm, 400 μm, 450 μm, 500 μm, etc. This arrangement ensures a sufficient spacing S4 between the edge sealing structure 7 and the first reinforcing structure 8. Furthermore, the problem of the non-display area 1 b being too large due to an excessive spacing S4 can be avoided.

[0073] The display module may further include a second reinforcement structure 9. The second reinforcement structure 9 may be located within the second gap S2 and supported between the drive backplane 2 and the cover plate 3. By providing the second reinforcement structure 9, the cover plate 3 at the second gap S2 can be supported. This configuration prevents bending of the cover plate 3 caused by unevenness between the upper surface of the filling support structure 6 and the upper surface of the support stop structure 5, thereby preventing Newton rings in the display module and improving the display quality of the display module.

[0074] The second reinforcement structure 9 is located between the area of ​​the first vertex 52 and the light-emitting structure 4. The upper surface of the area where the first vertex 52 of the support stop structure 5 is located is prone to unevenness with the sealing and filling structure. Therefore, arranging the second reinforcement structure 9 in the area where the first vertex 52 is located can further reduce the Newton ring problem of the display module, thereby improving the display effect of the display module.

[0075] The spacing S5 between the second reinforcement structure 9 and the light-emitting structure 4 can be greater than or equal to 5μm to ensure that there is a sufficient spacing S5 between the second reinforcement structure 9 and the light-emitting structure 4 to ensure that the display module does not have color deviation problems when displaying. In addition, the spacing S5 between the second reinforcement structure 9 and the light-emitting structure 4 can be less than or equal to 400μm. For example, the spacing S5 between the second reinforcement structure 9 and the light-emitting structure 4 can be 5μm, 10μm, 50μm, 100μm, 150μm, 200μm, 250μm, 300μm, 350μm, 400μm, etc. This setting can avoid the problem of the non-display area 1b of the display module being too large due to the excessive spacing S5 between the second reinforcement structure 9 and the light-emitting structure 4, and can increase the proportion of the display area 1a, thereby improving the user's viewing experience.

[0076] In some embodiments, the support stop structure 5, the first reinforcement structure 8 and the second reinforcement structure 9 can be an integrated structure, that is, the support stop structure 5, the first reinforcement structure 8 and the second reinforcement structure 9 can be manufactured through an integrated manufacturing process, thereby reducing the process steps for manufacturing the support stop structure 5, the first reinforcement structure 8 and the second reinforcement structure 9, thereby improving the manufacturing efficiency of the display module.

[0077] In some embodiments of the present disclosure, Figure 2 As shown, the display module may further be provided with a substrate 10 , and the driving backplane 2 may be provided on the surface of the substrate 10 to support and protect the driving backplane 2 .

This disclosure is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein.
