It is designed with a bending area, and part of the structure of the display panel is bent to the back through the bending area, so as to achieve a narrow bezel design. In order to protect the bending area, a protective layer is usually provided outside the bending area to reduce the risk of damage to the bending area caused by external forces. However, the existing protective layer has a poor effect, and problems such as fracture are likely to occur in the protective layer itself and the protected screen body part. Summary of the Invention

[0006] The first main structures and the second main structures are alternately arranged on both sides of the substrate layer in sequence, and the orthographic projection of the first main structure on the substrate layer partially overlaps with the orthographic projections of two adjacent second main structures on the substrate layer; the first main structure and two adjacent second main structures corresponding to it form a shaping structure;

Detailed implementation manners

[0031] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0032] Application Overview

[0033] Refer to Figure 1 , Figure 1 is a schematic structural diagram of an existing display module. As Figure 1 shown, the display module includes a display panel 1, a support film 2, a composite tape 3, and a pad filling 4.

[0034] Among them, the display panel 1 includes a display area 11 and a non - display area 12. The display area 11 includes a plurality of sub - pixels arranged in an array (not shown in the figure) for light - emitting display. The non - display area 12 includes a bending area 121 and a bonding area 122. The bonding area 122 is provided with a plurality of bonding pads (PADs) for bonding a driving chip and a flexible circuit board (not shown in the figure). The function of the bending area 121 is to reduce the border. Specifically, the bonding area 122 is bent to the back (backlight side) of the display area 11 through the bending area 121, so that the space occupied by the bonding area 122 is adjusted from the border position to the back position of the display area 11, thereby reducing the border.

[0035] The support film 2 plays a supporting role for the display area 11 and the bonding area 122 of the display panel 1. The composite tape 3 includes multiple composite film layers and plays roles such as insulation. The pad filling 4 plays a role in increasing the bending radius, avoiding problems such as inconvenience in bending when the bending radius is too small and easy breakage of the bending area 121.

[0036] For the bending region 121, it includes multiple traces inside for realizing the electrical connection of the devices in the display region 11 and the bonding region 122. And, as Figure 1 shown, the thickness of the bending region 121 is generally less than that of the display region 11 (the reason is that the bending region 121 does not include light-emitting sub-pixels, and it is easier to bend when reducing the thickness of the bending region 121). Based on this, in order to protect the thinner bending region 121 and avoid problems such as fracture (especially the fracture of the internal traces), generally, a bending protection layer (BPL) 5 is considered to be provided on the outer side of the bending region 121, so as to improve the strength of the bending region 121 and reduce the risk of functional abnormalities caused by physical damage.

[0037] In addition, during the design, as Figure 1 shown, after the bending region 121 is bent, it should be an ideal circular arc transition shape. However, in reality, since the bending protection layer 5 of the bending region 121 cannot provide sufficient "shaping" support for the bending region 121, therefore, it is difficult for the bending region 121 to reach the ideal circular arc shape after bending. As Figure 2 shown, the actual product more presents a near-elliptical arc shape after bending, especially after the product ages, this phenomenon will be more obvious. Compared with the ideal circular arc shape, in the elliptical arc shape, the bending region 121 will face the problem of uneven stress distribution. Referring to Figure 2 , the stress in region B will be significantly greater than that in region A and region C, so local cracks may appear in region B of the bending region 121, and in severe cases, it will lead to an open circuit of the internal traces, thus affecting the display function.

[0038] In view of this, the present invention provides an improved bending protection layer solution to solve the problem that the bending region cannot maintain an ideal circular arc shape. The following non-limitingly illustrates the specific implementation solutions through several examples or embodiments.

[0039] Exemplary Shaping Protective Layer

[0040] Referring to Figure 3 , Figure 3 is a schematic structural diagram of the shaping protection layer provided in an embodiment of the present invention. As Figure 3As shown in the figure, the shaping protection layer 51 of this embodiment includes a substrate layer 51c, a plurality of first main structures 51a spaced apart on the first side of the substrate layer 51c, and a plurality of second main structures 51b spaced apart on the second side of the substrate layer 51c; the first main structures 51a and the second main structures 51b are alternately arranged on both sides of the substrate layer 51c in sequence, and the orthographic projection of the first main structure 51a on the substrate layer 51c overlaps partially with the orthographic projections of two adjacent second main structures 51b on the substrate layer 51c (that is, the first main structure 51a and two adjacent second main structures 51b overlap partially in the thickness direction); the first main structure 51a and two adjacent second main structures 51b corresponding to it form a shaping structure 51s. The shaping protection layer 51 is used to protect the bending area after being disposed on the bending area of the display panel 1, and to keep the bent bending area in a preset bending form through the shaping structure 51s. Among them, the preset bending form can be an ideal arc or a form similar to an arc.

[0041] First of all, it should be noted that in each embodiment of the present invention, unless otherwise specified, "a plurality of" means at least two.

[0042] In addition, the substrate layer 51c of the shaping protection layer 51 plays a supporting role for the first main structure 51a and the second main structure 51b. And the resistance of the substrate layer 51c during bending should not be too large. Therefore, the substrate layer 51c preferably uses a substrate with good plasticity, such as it can include memory foam (or other materials with slow rebound performance) or rolled grid copper-based materials, etc.

[0043] The first main structures 51a and the second main structures 51b on both sides of the substrate layer 51c are alternately distributed, and there are gaps between adjacent first main structures 51a and adjacent second main structures 51b (no material is filled in the gaps), thus forming a structure similar to a stitch line, that is, the adjacent first main structures 51a and adjacent second main structures 51b are separated by the stitch line structure.

[0044] Through the above design, after the shaping protective layer 51 is disposed in the bending area before bending and then bent, the substrate layer 51c will deform under the action of bending stress, and the first main structure 51a and the second main structure 51b on both sides of the substrate layer 51c will partially fill the gap portions on both sides of the substrate layer 51c (the gap portions only include air and do not include other filling materials), and generate interaction forces. Specifically, the overlapping portions of the first main structure 51a and two adjacent second main structures 51b in the thickness direction can provide interaction forces to maintain each other in a specific shape. Based on this, the shaping protective layer 51 can provide a supporting force through the shaping structure 51s to keep the bending area in an ideal bending shape (i.e., the above-mentioned preset bending shape), so that the bending shape of the bending area will not change significantly due to product aging or other reasons, achieving better protection for the bending area, thereby weakening the uneven stress distribution in the bending area, making the bending area in a better structural shape, and further reducing the risk of local cracks or fractures.

[0045] The specific principle is as follows: Referring to Figure 4 , in the bending shape, due to the existence of the first main structure 51a on the outer side of the substrate layer 51c, it is equivalent to converting the arc of the ideal shape into short straight lines (i.e., the arc is composed of multiple short straight lines) at local positions, and the stitching line positions between adjacent first main structures 51a on the outer side of the substrate layer 51c are supported by the second main structures 51b on the inner side of the substrate layer 51c. And due to the existence of the alternating second main structures 51b on the inner side, local "fitting" is achieved at the stitching line positions between adjacent first main structures 51a on the outer side, so as to be closer to the arc structure, realizing the transition of the local bending from the trajectory line L1 (dashed line) to the trajectory line L2 (solid line), and making the abrupt connection points between the original adjacent first main structures 51a achieve a smooth transition. Moreover, due to the supporting forces in different directions provided by the first main structure 51a and the second main structure 51b, the shaping protective layer 51 structure can be in a stable shape (similar to the structure of a tank chain), and thus the shaping protective layer 51 can be maintained in a shape approximately similar to an ideal arc, so that the stress in the upper region B thereof is released to the regions A and C, enabling the stress to be distributed more evenly and avoiding problems such as local fractures caused by excessive stress differences.

[0046] Furthermore, after the shaping protection layer 51 is disposed on the bending area of the display panel, the first main structure 51a and the second main structure 51b alternately arranged on both sides of the substrate layer 51c can support the bending area, and the shaping protection layer 51 will not undergo obvious deformation after the product ages. Thus, the uneven stress distribution in the shaping and bending areas can be weakened, enabling the bending area to be in an ideal preset bending form (such as an arc structure form), thereby greatly reducing the risk of local fracture, decreasing the incidence of abnormal display panel functions, enhancing the reliability and stability of the product structure, and improving the product quality.

[0047] Among them, to better achieve the above object, generally, the strength of the materials of the first main structure 51a and the second main structure 51b needs to be greater than the strength of the material of the substrate layer 51c. Thus, when the first main structure 51a and the second main structure 51b are subjected to the pressure caused by bending, they can better maintain their initial forms and avoid large deformations. For example, the materials of the first main structure 51a and the second main structure 51b can be polyethylene terephthalate (PET), which has good creep resistance, fatigue resistance, friction resistance, and dimensional stability. Of course, it can be understood that the first main structure 51a and the second main structure 51b can also use other materials with similar properties as long as they can meet the actual use requirements, and specific limitations are not imposed.

[0048] In addition, continuing to refer to Figure 3 , in some embodiments, the intervals between the multiple first main structures 51a arranged at intervals are equal, and at the same time, the intervals between the multiple second main structures 51b arranged at intervals are also equal. This facilitates design and preparation and can also better ensure uniform stress distribution on the shaping protection layer 51 after bending.

[0049] In addition, continuing to refer to Figure 3, in some embodiments, the distance a1 between adjacent first main body structures 51a is less than the width a2 of the first main body structure 51a, and the distance b1 between adjacent second main body structures 51b is less than the width b2 of the second main body structure 51b. The width a1 of the first main body structure 51a, that is, the dimension of the first main body structure 51a along the tangent direction of the bending arc. Similarly, the width b1 of the second main body structure 51b, that is, the dimension of the second main body structure 51b along the tangent direction of the bending arc. With such a setting, it is equivalent to increasing the ratio of the first main body structure 51a and the second main body structure 51b along the tangent direction of the bending arc, thereby providing a greater supporting force. However, it should be noted that the widths of the first main body structure 51a and the second main body structure 51b cannot be too large. If they are too large, the shaped protective layer 51 after bending will deviate from the ideal arc shape (not smooth enough), which is not conducive to the uniform distribution of stress. At the same time, the distance a1 between the first main body structures 51a and the distance b1 between adjacent second main body structures 51b cannot be too small, otherwise it is not conducive to bending.

[0050] Furthermore, in some embodiments, the distance a1 between adjacent first main body structures 51a is equal to the distance b1 between adjacent second main body structures 51b, and the width a2 of the first main body structure 51a is equal to the width b2 of the second main body structure 51b. In this way, it is convenient for design and preparation in practical applications. However, it can be understood that in other embodiments, the distance a1 between adjacent first main body structures 51a may not be equal to the distance b1 between adjacent second main body structures 51b, and furthermore, the width a2 of the first main body structure 51a may not be equal to the width b2 of the second main body structure 51b, and the object of the present invention can still be achieved at this time.

[0051] In addition, in practice, the width a2 of the first main body structure 51a is greater than the distance b1 between adjacent second main body structures 51b, and the width b2 of the second main body structure 51b is greater than the distance a1 between adjacent first main body structures 51a. In this way, partial overlap of the first main body structure 51a and the second main body structure 51b in the thickness direction is achieved.

[0052] In addition, continue to refer to Figure 3 , in some embodiments, the cross-sectional shapes of the first main body structure 51a and the second main body structure 51b along the thickness direction of the protective layer are rectangular, and the rectangular structure can provide better supporting force. However, it can be understood that the cross-sectional shapes of the first main body structure 51a and the second main body structure 51b along the thickness direction of the protective layer are not limited, and other shapes can also be used, such as rounded rectangles or ellipses, etc.

[0053] In addition, multiple spaced-apart first main body structures 51a and multiple spaced-apart second main body structures 51b can be formed by etching. Taking the first main body structure 51a as an example, the specific process is as follows: First, a whole-layer film layer is formed on one side of the substrate layer using the material corresponding to the first main body structure 51a (such as PET, etc.). Then, a stitch line structure is etched on the corresponding film layer through etching, and the multiple spaced-apart first main body structures 51a can be separated by the stitch line structure.

[0054] The structure and working principle of the shaping protective layer 51 provided by the present invention have been exemplarily described through multiple embodiments. However, it can be understood that for the convenience of practical application, in addition to the above-mentioned structure, the shaping protective layer 51 can further include other structures, which will be exemplarily described in subsequent embodiments.

[0055] Exemplary Display Module

[0056] Referring to Figures 5 - 7 , Figure 5 is a schematic structural diagram of a display module provided in an embodiment of the present invention. Figure 6 is Figure 5 a partial enlarged schematic diagram of the area P of the display module shown in Figure 7 is a schematic structural diagram of the bending protective layer of the display module before bending. As Figures 5 - 7 shown, the display module of this embodiment includes a display panel 1, the display panel 1 includes a display area 11 and a non-display area 12 provided on at least one side of the display area 11, and the non-display area 12 includes a bending area 121. In addition, the display module further includes a bending protective layer 5 provided in the bending area 121 of the display panel 1, and the bending protective layer 5 includes the shaping protective layer 51 described in the above embodiment and protective outer layers 52 provided on both sides of the shaping protective layer 51.

[0057] Specifically, in order for the shaping protective layer 51 to play a sufficient shaping and supporting role, its overall strength is relatively large. In practice, its overall thickness cannot be too large, otherwise its bending difficulty will be relatively large and it will be inconvenient for practical applications. However, when the thickness of the shaping protective layer 51 is small, the problem is that its protection performance will be relatively poor, that is, the effect of protecting the bending area 121 from external force damage is relatively poor. Based on this, in the bending protective layer 5 of this embodiment, in addition to including the above-mentioned shaping protective layer 51, protective outer layers 52 are also provided on both sides of the shaping protective layer 51, so as to mainly protect the bending area 121 through the protective outer layers 52. Among them, the protective outer layer 52 can adopt the bending protective layer design in the existing solution and is formed by coating. Its specific materials, structure and protection principle will not be elaborated here. In this way, the protective outer layer 52 provides protection, and the shaping protective layer 51 provides plastic support for the protective outer layer 52. The two cooperate with each other, which can not only protect the bending area 121, but also keep the bending area 121 in the preset bending form, thus avoiding problems such as local cracks in the bending area 121.

[0058] It should be noted that in the above embodiments, the bending protective layer 5 includes the protective outer layers 52 provided on both sides of the shaping protective layer 51. However, in fact, in some other embodiments, the bending protective layer 5 may only include the shaping protective layer 51 and the protective outer layer 52 provided on one side of the shaping protective layer 51. At this time, its purpose can still be achieved. In addition, Figure 7 In the corresponding embodiment, the thicknesses of the protective outer layers 52 on both sides of the shaping protective layer 51 are the same. However, in some other embodiments, the thicknesses of the protective outer layers 52 on both sides of the shaping protective layer 51 may also be different, and its purpose can still be achieved.

[0059] In addition, the specific structures and uses of the display area 11 and the bending area 121 of the non-display area 12 of the display panel 1 are the same as those of the same structures of the existing display panel 1 and will not be elaborated here. And, in addition to the display panel 1 and the bending protective layer 5 provided in the bending area 121 of the display panel 1, the display module of this embodiment may also include other structures, such as Figure 1 the display module shown, the display module of this embodiment may also include a support film, a composite tape, a padding filling, etc. Its specific structure and use will not be elaborated either.

[0060] Continue to refer to Figures 5 - 7, in some embodiments, the thickness of the shaping protective layer 51 is less than that of the protective outer layer 52. Specifically, when forming the protective outer layer 52 by coating according to the existing solution, due to its material properties, in order to better play a buffering and protective role, a protective outer layer 52 with a larger thickness (greater than the shaping protective layer 51) is usually considered. Also, since the strength of the shaping protective layer 51 is greater than that of the protective outer layer 52, that is, the strength of the shaping protective layer 51 is relatively large, the thickness of the shaping protective layer 51 cannot be too large, otherwise the actual bending difficulty will also be relatively large. Therefore, in some embodiments, it is set that the thickness of the shaping protective layer 51 is less than that of the protective outer layer 52 to ensure easy bending and that the overall thickness of the bending protective layer 5 will not be too large to avoid other adverse effects.

[0061] In addition, since the smaller the bending radius of the bending area 121, the greater the possibility of local cracks appearing after bending, therefore, the solution of the above embodiments is more obvious in the solution with a smaller radius, and is particularly applicable to the solution with a bending radius less than 0.25 mm (millimeter).

[0062] In addition, continue to refer to Figure 5 , in some embodiments, the non-display area 12 further includes a bonding area 122 connected to the display area 11 through the bending area 121, and the shaping protective layer 51 (or the bending protective layer 5) is provided in the bending area 121 and extends to the bonding area 122. Such a setting is equivalent to increasing the size of the shaping protective layer 51 (or the bending protective layer 5), which can better play a shaping and supporting role for the bending area 121. At the same time, when directly or indirectly attaching the shaping protective layer 51 (or the bending protective layer 5) to the display panel 1, it can also increase the attachment area to ensure that the shaping protective layer 51 (or the bending protective layer 5) will not peel off due to bending.

[0063] In addition, it should be noted that in addition to the structures mentioned in the above embodiments, the display module further includes other structures necessary to implement its functions. For example, it may further include structures such as a cover plate, an optical adhesive layer, and a polarizer disposed on the light-emitting side of the display panel. However, the present invention has not made improvements to them, so they will not be described one by one here.
