Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to a display screen module and an electronic device. Background Art

[0002] Currently, quad-curved display screens are widely used in electronic devices such as mobile phones, tablets, and smart wearables. They not only help expand the display area but also improve the appearance. However, the quad-curved design is primarily limited by the lamination capabilities of the display layer. Deep quad-curved displays, in particular, further reduce the black borders of the display cover and increase the arc depth and width. This increases the risk of lamination between the display cover and the display layer, and can easily cause cracks, wrinkles, bubbles, and other defects in the display layer.

[0003] To overcome these issues, related art has proposed a display screen comprising a cover plate, an adhesive layer, and a display layer. The adhesive layer is recessed relative to the cover plate to alleviate these issues. However, this inward contraction of the adhesive layer weakens its protective effect on the display layer and can easily lead to problems such as poor airtightness. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a display screen module and an electronic device that can at least solve the problems of weakened protection of the display layer and poor air tightness caused by the shrinkage of the adhesive layer.

[0005] In order to solve the above technical problems, this application is implemented as follows:

[0006] The embodiment of the present application provides a display screen module, comprising: a cover plate, a first adhesive layer, and a display layer stacked sequentially from outside to inside along the thickness direction of the display screen module;

[0007] The cover plate includes a first arc-shaped edge having a first edge end located at a curved side of the display screen module;

[0008] The first adhesive layer includes a second curved edge that is in contact with the first curved edge. The second curved edge has a second edge end located at a curved side of the display module. At least a portion of the second edge end is flush with the first edge end. The second curved edge has a non-uniform thickness along its extension direction.

[0009] The display layer includes a third arc-shaped edge that is in contact with the second arc-shaped edge. The third arc-shaped edge has a third edge end located at the arc-shaped side of the display screen module. The third edge end is indented relative to the second edge end.

[0010] The embodiment of the present application further provides an electronic device, comprising: a device body and the above-mentioned display screen module;

[0011] The display screen module is arranged on the device body.

[0012] In the embodiment of the present application, at least a portion of the second edge of the first adhesive layer is flush with the first edge of the cover plate, thereby alleviating the problem of poor sealing and reduced protection of the display layer caused by the inward shrinkage of the second edge of the first adhesive layer. The second curved edge of the first adhesive layer also provides support for the first curved edge of the cover plate, thereby improving the cover plate's impact resistance. In addition, compared to the method of uniform thickness adhesive layers, the second curved edge adopts a non-uniform thickness setting, which can achieve a smooth transition, improve the bonding effect to a certain extent, and effectively alleviate bonding problems such as bubbles.

[0027] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0029] The embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0030] refer to Figures 1 to 6 The embodiment of the present application discloses a display screen module 10, which is applied to an electronic device, wherein the display screen module 10 can be a four-curved module. The disclosed electronic device includes a cover plate 11, a first adhesive layer 12 and a display layer 13, and the cover plate 11, the first adhesive layer 12 and the display layer 13 are stacked in sequence from the outside to the inside along the thickness direction of the display screen module 10. It should be noted here that the thickness direction of the display screen module 10 can be Figures 1 to 5 The up and down directions of each view in .

[0031] The cover plate 11 is located at the outermost layer and protects the display layer 13. It also prevents dust, impurities, water, etc. from entering the display screen module 10, thereby ensuring the normal operation of the display screen module 10. The cover plate 11 is transparent, and the image displayed by the display layer 13 can be transmitted outward through the cover plate 11 for viewing by the user. For example, the cover plate 11 can be made of glass, plastic, etc., but other materials are also possible and are not specifically limited here.

[0032] The display layer 13 is used to display images, and can be provided on the inner side of the cover plate 11. For example, the display layer 13 can be a flexible display layer, a rigid display layer, etc., and the specific form is not limited.

[0033] like Figure 1 As shown, the first adhesive layer 12 is located between the cover plate 11 and the display layer 13, and is used to bond the cover plate 11 and the display layer 13 together. The first adhesive layer 12 can be a transparent adhesive layer to ensure that the image displayed by the display layer 13 can be transmitted through the first adhesive layer 12. Alternatively, the first adhesive layer 12 can be a liquid optical adhesive, a semi-solid optical adhesive, or a solid optical adhesive, that is, the first adhesive layer 12 can be an optical characterization (OCR) or optical characterization (OCA) adhesive.

[0034] In the embodiment of the present application, the display screen module 10 is a curved display screen module 10, so that the display screen module 10 can have curved sides. Optionally, the two opposite sides of the display screen module 10 can be curved sides; or, all four sides of the display screen module 10 are curved sides; of course, the four corners of the display screen module 10 can also be curved corners. In addition, other forms are also possible, which are not specifically limited here. Taking the four-curved display screen module 10 as an example, its four sides are all curved sides, and its four corners are all curved corners.

[0035] If the display screen module 10 is a curved display screen module 10, the cover plate 11 may include a first curved edge 111. With respect to the electronic device, the edge of the cover plate 11 curves and extends from the outside to the inside along its own extension direction to form the first curved edge 111. Optionally, the first curved edge 111 may be a circular arc edge, and its specifications may be 2.5D, 3.0D, 4.0D, etc. Accordingly, the display screen module 10 may be a 2.5D screen, a 3.0D screen, a 4.0D screen, etc. Of course, other specifications are also possible.

[0036] Correspondingly, the first adhesive layer 12 includes a second curved edge 121, which is in contact with the first curved edge 111 of the cover plate 11. In this way, the edge of the first adhesive layer 12 can be adapted to the edge shape of the cover plate 11 to prevent the edge of the first adhesive layer 12 from interfering with the installation of the cover plate 11, thereby ensuring that the cover plate 11 can be installed smoothly.

[0037] In addition, the display layer 13 includes a third curved edge 131, which aligns with the second curved edge 121 of the first adhesive layer 12. This increases the contact area between the display layer 13 and the first adhesive layer 12, thereby enhancing the protective effect of the first adhesive layer 12 on the display layer 13. Furthermore, compared to a flat display layer 13, the curved display layer 13 with the third curved edge 131 can increase the area of the display layer 13 to a certain extent, thereby facilitating an increase in the display region.

[0038] In the embodiment of the present application, the first curved edge 111 has a first edge end 1111 located at the curved side of the display screen module 10. When the display screen module 10 is installed to the device body 20 of the electronic device, the first curved edge 111 can be connected to the device body 20 through the first edge end 1111, which can improve the stability and reliability of the connection between the display screen module 10 and the device body 20 to a certain extent.

[0039] The second curved edge 121 includes a second edge end 1211 located at the curved side of the display screen module 10, with at least a portion of the second edge end 1211 flush with the first edge end 1111. The third curved edge 131 includes a third edge end 1311 located at the curved side of the display screen module 10, with the third edge end 1311 set back relative to the second edge end 1211, i.e., the second edge end 1211 protrudes from the third edge end 1311. This arrangement provides a certain degree of protection for the third edge end 1311 via the second edge end 1211, thereby improving the impact resistance of the display screen module 10 and enhancing the sealing performance of the edge of the display screen module 10, thereby alleviating the problem of external dust, impurities, water, etc. entering the interior of the display screen module 10 and contacting the display layer 13, thereby causing damage to the display screen module 10.

[0040] In addition, the second curved edge 121 is not arranged with uniform thickness along its own extension direction, that is, the thickness dimensions of different areas of the second curved edge 121 along its own extension direction are not completely the same. In this way, the first adhesive layer 12 can have a smooth transition in the edge area, which is beneficial to improving the bonding yield and ensuring the reliability of the bonding between the first adhesive layer 12 and the cover plate 11 and the display layer 13.

[0041] Based on the above arrangement, at least a portion of the second edge 1211 of the first adhesive layer 12 in the embodiment of the present application is flush with the first edge 1111 of the cover plate 11, thereby alleviating the problem of poor sealing and reduced protection of the display layer 13 caused by the complete inward retraction of the second edge 1211 of the first adhesive layer 12. Furthermore, the second curved edge 121 of the first adhesive layer 12 also supports the first curved edge 111 of the cover plate 11, thereby improving the impact resistance of the cover plate 11. Furthermore, compared to a uniform thickness adhesive layer approach, the non-uniform thickness of the second curved edge 121 achieves a smooth transition, which, to a certain extent, improves the lamination effect and effectively alleviates problems such as lamination bubbles.

[0042] refer to Figures 1 to 3 、 Figure 5In some embodiments, the thickness of the second curved edge 121 gradually decreases along its extension direction toward the second edge end 1211. This allows for a more uniform transition of the first adhesive layer 12 from the area away from the second edge end 1211 toward the second edge end 1211, thereby improving the fit of the second curved edge 121 with the first curved edge 111 and the third curved edge 131, thereby alleviating the problem of bubbles forming during lamination. For example, the cross-section of the second edge end 1211 can be wedge-shaped.

[0043] In other embodiments, the thickness of the second curved edge 121 first increases and then decreases along the extension direction of the second curved edge 121 and toward the second edge end 1211. This also allows for a more uniform transition of the first adhesive layer 12 from the area away from the second edge end 1211 toward the second edge end 1211, thereby improving the fit of the second curved edge 121 with the first curved edge 111 and the third curved edge 131, thereby alleviating the problem of bubbles forming during lamination. For example, the cross-section of the second edge end 1211 can be crescent-shaped.

[0044] It should be noted that the shapes of the second curved edge 121 differ between the two aforementioned approaches, likely due to differences in the materials used for the first adhesive layer 12. When the first adhesive layer 12 is a solid or semi-solid optical adhesive, it is distributed not only along the first curved edge 111 of the cover plate 11 but also in areas other than the first curved edge 111. Furthermore, its thickness is relatively large, resulting in a relatively large overall thickness for the display screen module 10 formed in this configuration. When the first adhesive layer 12 is a liquid optical adhesive, it is primarily distributed in areas near the second curved edge 121 and is relatively thin, resulting in a relatively small overall thickness for the display screen module 10 formed in this configuration.

[0045] refer to Figure 1 In some embodiments, the second curved edge 121 may include a first curved surface 1212 and a second curved surface 1213 disposed opposite to each other along the curved side of the display module 10, wherein the first curved surface 1212 is in contact with the first curved edge 111, and the second curved surface 1213 is in contact with the second curved edge 121. In this way, the display layer 13 and the cover plate 11 can be stably and reliably connected at the edge through the first adhesive layer 12, thereby alleviating the problem of lamination bubbles.

[0046] Considering that the edge of the cover plate 11 needs to be connected to the device body 20, while the edge of the display layer 13 does not need to be connected to the device body 20, the shape of the display layer 13 is different from that of the cover plate 11. In some embodiments, when designing the second curved edge 121 of the first adhesive layer 12, the curvature of the second curved surface 1213 can be smaller than the curvature of the first curved surface 1212, such as Figure 1 As shown. Based on this, the curvature of the first curved surface 1212 of the second curved edge 121 can be adapted to the curvature of the first curved edge 111 to ensure good adhesion between the two, and the curvature of the display layer 13 can be designed to be smaller, improving the situation where the display layer 13 fails due to large-curvature adhesion, and the curvature of the second curved surface 1213 of the second curved edge 121 can be adapted to the curvature of the display layer 13 to ensure good adhesion between the two. Therefore, it is possible to effectively adhere to the large curved surface of the cover plate 11 and reduce the curvature of the bonding surface of the display layer 13 to improve the bonding yield, thereby ensuring the reliability, stability and sealing of the connection of the display screen module 10 in the curved edge area, and can increase the limit value of curved surface adhesion to create a product with more competitive appearance. In addition, it can also meet the appearance requirements of products with larger curvatures.

[0047] It should be noted here that no matter what type of optical adhesive the first adhesive layer 12 is, the curvature of the second curved surface 1213 of its second curved edge 121 is smaller than the curvature of the first curved surface 1212, thereby adapting the second curved edge 121 to the good fit with the first curved edge 111 and the third curved edge 131.

[0048] refer to Figure 2 In some embodiments, the first adhesive layer 12 may include at least one first sub-adhesive layer 12a and a second sub-adhesive layer 12b. The at least one first sub-adhesive layer 12a is stacked on the inner surface of the cover plate 11, and the second sub-adhesive layer 12b is stacked between the first sub-adhesive layer 12a and the display layer 13. Based on this configuration, at least one first sub-adhesive layer 12a is well bonded to the cover plate 11, the second sub-adhesive layer 12b is well bonded to the display layer 13, and the first sub-adhesive layer 12a and the second sub-adhesive layer 12b are well bonded to each other. Thus, the stability and reliability of the bond between the display layer 13 and the cover plate 11 can be ensured. Furthermore, at least one first sub-adhesive layer 12a and the second sub-adhesive layer 12b can also play a certain buffering role to buffer the force acting on the cover plate 11, thereby preventing the force acting on the cover plate 11 from being completely transferred to the display layer 13 and causing damage to the display layer 13.

[0049] At least one first sub-adhesive layer 12a is located at the edge end of the curved side of the display screen module 10 and is flush with the first edge end 1111. In this way, the first adhesive layer 12 can be completely fitted with the cover plate 11. Compared with the inward-retracted form of the first adhesive layer 12, the load-bearing capacity and impact resistance of the cover plate 11 are improved, and it is beneficial to improve the sealing effect.

[0050] The edge of the second sub-glue layer 12b located at the curved side of the display screen module 10 is not flush with the first edge 1111, so that the first glue layer 12 can adapt to the device body 20 without causing installation interference with the device body 20 and affecting the reliable installation of the cover plate 11 and the device body 20. For example, the edge of the second sub-glue layer 12b on the side connected to the first sub-glue layer 12a is flush with the edge of the first sub-glue layer 12a, while the edge of the second sub-glue layer 12b in the area away from the first sub-glue layer 12a extends obliquely toward the display layer 13 relative to the edge of the first sub-glue layer 12a.

[0051] In addition, each first sub-glue layer 12a is set with equal thickness at the second curved edge 121, and the second sub-glue layer 12b is set with non-equal thickness at the second curved edge 121. In this way, a smooth transition of the first glue layer 12 at the second curved edge 121 can be guaranteed, and both the first sub-glue layer 12a and the cover plate 11 can be reliably bonded, and the second sub-glue layer 12b and the display layer 13 can be reliably bonded, thereby effectively alleviating the problem of bonding bubbles.

[0052] In some embodiments, the modulus of the first sub-adhesive layer 12a can be smaller than the modulus of the second sub-adhesive layer 12b. That is, the first sub-adhesive layer 12a can be made of a low-modulus optical adhesive, and the second sub-adhesive layer 12b can be made of a high-modulus optical adhesive. Furthermore, the first sub-adhesive layer 12a can also be made of a high-viscosity optical adhesive. Thus, the first sub-adhesive layer 12a can be made of a low-modulus, high-viscosity optical adhesive, thereby ensuring a good bonding effect and alleviating the problem of bubbles during bonding.

[0053] The buffering performance of the second sub-glue layer 12b may be higher than that of the first sub-glue layer 12a. That is, the second sub-glue layer 12b may adopt optical glue with high buffering performance, and the first sub-glue layer 12a may adopt optical glue with low buffering performance.

[0054] Thus, the second sub-adhesive layer 12 b can be made of optical adhesive with high modulus and high buffering performance to ensure the overall buffering capacity of the display screen module 10 and the curvature of the bonding surface of the display layer 13 .

[0055] Optionally, at least one first sub-adhesive layer 12a can be molded and bonded at medium or high temperature to ensure high-area bonding, and the first sub-adhesive layer 12a can have certain viscoelasticity and deformation ability at high temperature; the second sub-adhesive layer 12b uses high modulus optical adhesive to ensure cohesion.

[0056] Based on the above configuration, the embodiment of the present application uses a combination of at least one first sub-glue layer 12 a and a second sub-glue layer 12 b to ensure the bonding effect at the edge of the display screen module 10 .

[0057] In some more specific embodiments, the number of the first sub-glue layer 12a may be one, two or more, which may be selected according to actual working conditions.

[0058] refer to Figure 3 In some embodiments, the display screen module 10 may further include a second adhesive layer 14 disposed between the first curved edge 111 and the second curved edge 121 , and the first curved edge 111 and the second curved edge 121 may be firmly adhered together by the second adhesive layer 14 .

[0059] Alternatively, the second adhesive layer 14 may be a liquid optical adhesive, wherein a mold may be used to seal the edge of the cover plate 11, and the liquid optical adhesive may be injected, and then UV curing may be used, and the mold may be demolded to form the desired uneven thickness. Of course, the second adhesive layer 14 may also be a solid optical adhesive or a semi-solid optical adhesive.

[0060] Alternatively, liquid optical adhesive can be layered on the curved surface of cover plate 11 using inkjet printing, with the adhesive cured layer by layer to achieve high-efficiency filling of the curved surface and maintain strong adhesion after curing. The printed liquid optical adhesive is then bonded to first adhesive layer 12 (or to display layer 13) to prevent wrinkles and bubbles. Furthermore, compared to bonding multiple first adhesive layers 12, using second adhesive layer 14 in conjunction with first adhesive layer 12 can also help reduce the thickness of display module 10, thereby achieving lightweighting.

[0061] It should be noted here that, in the embodiment of the present application, the cover plate 11 and the display layer 13 can be connected through the first adhesive layer 12, through the second adhesive layer 14, or through the cooperation of the first adhesive layer 12 and the second adhesive layer 14. The specific connection form can be selected according to the actual working conditions.

[0062] Among them, such as Figure 4 As shown, when the cover plate 11 and the display layer 13 are connected by a second adhesive layer 14, the second adhesive layer 14 has a fourth edge 141 located at the curved side of the display module 10. This fourth edge 141 is flush with the first edge 1111, and the display layer 13 is set back relative to the second adhesive layer 14. In this way, the second adhesive layer 14 can fully adhere to the cover plate 11, thereby improving the impact resistance of the cover plate 11 and the sealing effect between the cover plate 11 and the device body 20. The second adhesive layer 14 also protects the display layer 13. In this way, using the second adhesive layer 14 instead of the first adhesive layer 12 can solve the problem of poor adhesion while meeting the requirements of thinning the entire device and improving the lightness and thinness.

[0063] like Figure 3As shown, when the cover plate 11 and the display layer 13 are connected via the first adhesive layer 12 and the second adhesive layer 14, the second adhesive layer 14 may have a fourth edge 141 that is flush with the first edge 1111 and the second edge 1211. This ensures that the second adhesive layer 14 is fully bonded to the cover plate 11, thereby improving the impact resistance of the cover plate 11 and the sealing effect between the cover plate 11 and the device body 20. Furthermore, the second adhesive layer 14 protects the display layer 13 and improves its cushioning performance, thereby effectively alleviating the problem of forces acting on the cover plate 11 being transmitted to the display layer 13, causing damage to the display layer 13.

[0064] The second adhesive layer 14 is arranged to have a uniform thickness along its own extension direction. In this way, the second adhesive layer 14 can have a smooth transition in the edge area, thereby ensuring that no bubbles will appear between the second adhesive layer 14 and the cover plate 11, thereby ensuring the reliability of the bonding between the second adhesive layer 14 and the cover plate 11.

[0065] like Figure 3 and Figure 4 As shown, in some embodiments, the thickness of the second adhesive layer 14 increases and then decreases along the extension direction of the second adhesive layer 14 and toward the fourth edge end 141. Based on this, the second adhesive layer 14 can have a more uniform transition from the area away from the edge end to the edge end, thereby improving the adhesion between the second adhesive layer 14 and the cover plate 11 and the first adhesive layer 12, respectively, and alleviating the problem of lamination bubbles. For example, the cross-section of the second adhesive layer 14 can be crescent-shaped.

[0066] refer to Figure 5 In some embodiments, the display module 10 may further include an auxiliary material layer 15, which is cured and laminated to the side of the display layer 13 facing away from the cover plate 11. This increases the hardness of the auxiliary material layer 15 after curing, thereby improving its modulus and anti-overprinting capability through secondary curing. Furthermore, the lower hardness of the auxiliary material layer 15 before curing facilitates high-rate lamination. This configuration effectively alleviates the conflict between lamination and modulus.

[0067] It should be noted that the display screen module 10 may include the auxiliary material layer 15 when including the first adhesive layer 12 , the second adhesive layer 14 , or both the first adhesive layer 12 and the second adhesive layer 14 .

[0068] Furthermore, the auxiliary material layer 15 can have a fifth edge end 151 located at the curved side of the display screen module 10, and the fifth edge end 151 is flush with the third edge end 1311 of the display layer 13. In this way, the contact area of the auxiliary material layer 15 with the display layer 13 can be increased, thereby achieving full support for the display layer 13 and improving the supporting capacity of the display layer 13.

[0069] Optionally, the auxiliary material layer 15 may be made of a secondary hardened polymer material, such as a secondary hardened silicone gel. Specifically, before lamination, the auxiliary material layer 15 has a low hardness and high viscosity to meet the requirements of large-area lamination (e.g., large-area four-corner lamination). After lamination, the auxiliary material layer 15 is hardened using UV or temperature control to improve impact resistance, thereby meeting the dual requirements of hardness and modulus.

[0070] Based on the above display screen module 10, the embodiment of the present application also discloses an electronic device, such as Figures 1 to 6 As shown, the disclosed electronic device includes a device body 20 and the above-mentioned display screen module 10, wherein the display screen module 10 is provided in the device body 20. It should be noted that the specific structure and working principle of the device body 20 can refer to the existing technology and will not be elaborated here.

[0071] In addition, the display screen module 10 can be applied to straight-type electronic devices, foldable electronic devices, rollable electronic devices, sliding electronic devices, etc. Of course, it can also be applied to other scenarios and is not specifically limited here.

[0072] In summary, the adhesive layers (e.g., the first adhesive layer 12 and the second adhesive layer 14) in the embodiment of the present application are designed to be flush with the cover plate 11 without shrinkage, which can be beneficial to improving the impact resistance and sealing effect. By adopting a non-uniform thickness design, a uniform transition can be achieved to alleviate the problem of lamination bubbles.

[0073] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
