[0026] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0027] In the related art, the folding screen includes functional layers such as a substrate layer, a polarizing layer, a touch layer, and a cover layer, and the functional layers are bonded together by adhesive layers to form a complete screen assembly. When the folding screen is bent, the bending area of ​​the functional layer will bend and deform, thereby generating stress that may cause damage and fracture. At this time, the adhesive layer between adjacent functional layers can relieve stress to a certain extent, but the overall size of the functional layer is large, which increases the difficulty of releasing the stress of the adhesive layer. Simply reducing the size of the adhesive layer will affect the overall display effect of the screen assembly.

[0028] Figure 1 FIG. 1 is a schematic diagram of a cross-sectional structure of a screen assembly in an exemplary embodiment of the present disclosure. Figure 1 As shown, the screen assembly 1 includes: a plurality of functional layers 11 and at least two transparent connection layers 12. The functional layer 11 includes a bending portion 111. When the screen assembly 1 is bent, the bending portion 111 of each functional layer 11 is deformed accordingly. The transparent connection layer 12 is arranged between two adjacent functional layers 11 and is respectively connected to two adjacent functional layers 11 so that the adjacent functional layers 11 can be assembled and matched. Each transparent connection layer 12 is matched with a partial area of ​​the corresponding functional layer 11, and the longitudinal projections of all transparent connection layers 12 match the longitudinal projections of the functional layer 11, and the longitudinal projections of any two transparent connection layers 12 do not overlap each other.

[0029] Each transparent connection layer 12 cooperates with a partial area of ​​the functional layer 11 to facilitate stress buffering and release, and the cooperation of each transparent connection layer 12 to form a complementary structure also avoids the transparent connection layer 12 from interfering with the display effect of the screen assembly 1.

[0030] In the above embodiment, at least a portion of each transparent connection layer 12 cooperates with the bending portion 111 , so that each transparent connection layer 12 can independently implement stress buffering for the deformation of the functional layer 11 , thereby improving the buffering efficiency.

[0031] The present disclosure does not limit the number of the functional layers 11 and the transparent connection layers 12 disposed between adjacent functional layers 11. The structure of the transparent connection layer 12 is exemplarily described below by taking three functional layers 11 and two transparent connection layers 12 as an example:

[0032] The transparent connection layer 12 is a continuous structure, and the continuous transparent connection layer 12 is matched with a partial area of ​​the functional layer 11. When the functional layer 11 is deformed due to the bending of the screen assembly 1, the continuous transparent connection layer 12 implements stress buffering for the multiple functional layers 11 corresponding to the partial projection area. The transparent connection layer 12 corresponding to other areas of the functional layer 11 implements stress buffering for the multiple functional layers 11 corresponding to other partial projection areas. The above-mentioned continuous transparent connection layer 12 has a simple structure and low molding cost.

[0033] Figure 2 is a schematic structural diagram of a functional layer 11 and a corresponding transparent connection layer 12 in an exemplary embodiment of the present disclosure; Figure 3 is a schematic structural diagram of another functional layer 11 and a corresponding transparent connection layer 12 in an exemplary embodiment of the present disclosure; Figure 4 yes Figure 2 , Figure 3 A schematic diagram of the structure of the functional layer 11 and the transparent connection layer 12 cooperating with each other. Figure 2 , Figure 3 , Figure 4 As shown, the transparent connection layer 12 includes a plurality of connection parts 121 arranged at intervals. The above structural setting allows a gap to exist between any two connection parts 121. When the screen assembly 1 is bent and the transparent connection layer 12 generates stress, each connection part 121 can utilize the above gap to deform to release the stress, thereby improving the stress release efficiency and reducing the difficulty of the transparent connection layer 12 to release the stress. From the perspective of the overall screen assembly 1, the connection parts 121 of the upper and lower transparent connection layers 12 form a complementary structure, thereby avoiding the transparent connection layer 12 from interfering with the display of the screen assembly 1.

[0034] In the above embodiment, the transverse cross-section of the connecting portion 121 may be a rectangle, a trapezoid, a polygon, or a shape with an arc edge, etc., and the present disclosure is not limited thereto. When the transverse cross-section of the connecting portion 121 includes an arc edge, the arc edge can be used to enable the transparent connecting layer 12 to smoothly absorb and release stress, so that it can effectively match the stress changes in different regions of the functional layer 11. When the transverse cross-section of the connecting portion 121 is a rectangle, multiple connecting portions 121 can be arranged in an array along the extension direction of the bending portion 111 of the functional layer 11 to reduce the difficulty of forming the transparent connecting layer 12, and facilitate the upper and lower position matching between the multiple transparent connecting layers 12.

[0035] It should be noted that the width of the intervals between adjacent connecting portions 121 can be equal to facilitate the position correspondence of the upper and lower connecting portions 121 and the molding of the connecting portions 121; or, the width of the intervals between adjacent connecting portions 121 can be different so that the interval width corresponds to the stress of different regions of the functional layer 11. For example, when the stress generated by the functional layer 11 in the region is relatively dense, the interval width can be reduced to enhance the buffering capacity of the connecting portion 121 for the stress in the region.

[0036] In addition, the structures of any two connecting parts 121 may be the same, or the structures of two connecting parts 121 may be different, and the present disclosure does not limit this. When the structures of any two connecting parts 121 are the same, on the one hand, the molding cost of the transparent connecting layer 12 is reduced, and on the other hand, it is convenient for the coordination between the projections of all transparent connecting layers 12, and the influence of the transparent connecting layer 12 on the display effect of the screen assembly 1 is reduced. When there are two connecting parts 121 with different structures, the structure of the connecting part 121 can be set according to the different stresses in different areas of the functional layer 11 to improve the stress buffering efficiency.

[0037] In order to provide different levels of stress buffering according to the deformation degree of different areas of the screen assembly 1, the transverse cross-sectional area of ​​the transparent connection layer 12 can also be optimized:

[0038] In one embodiment, the functional layer 11 includes a bending portion 111 and an extension portion connected to the bending portion 111. When the screen assembly 1 is bent, the bending portion 111 undergoes a large deformation, and the extension portion cooperates with the bending portion 111 to undergo a small deformation. At this time, the transparent connection layer 12 corresponding to the bending portion 111 produces a large stress buffering effect, thereby improving the utilization rate of the transparent connection layer 12.

[0039] For example, the rectangular screen assembly 1 is divided into three regions: the upper part, the middle part, and the lower part, wherein the middle part is the bending region, and the bending portion 111 of the functional layer 11 corresponds to the middle region of the screen assembly 1. That is, the middle part of the screen assembly 1 is bent, causing the bending portion 111 of the functional layer 11 to undergo a large deformation, and other regions of the functional layer 11 undergo an adaptive deformation that is smaller than the bending portion 111. The stress distribution corresponding to the deformation of the functional layer 11 from the upper part to the middle increases linearly. Therefore, Figure 5 As shown, the transverse cross-sectional area of ​​the transparent connection layer 12 can be increased linearly from the extension portion to the bending portion 111, so that the transverse cross-sectional area of ​​the transparent connection layer 12 corresponding to the bending portion 111 gradually increases, and the stress buffering effect increases to the maximum from the edge of the extension portion to the center line of the bending portion 111, thereby improving the utilization rate of the transparent connection layer 12 in buffering stress.

[0040] In addition, the screen assembly 1 can also be divided into three areas: the left side, the middle, and the right side, and the deformation of the functional layer 11 corresponding to the three areas can be analyzed to obtain the corresponding stress change areas, thereby optimizing the transverse cross-sectional area distribution of the transparent connection layer 12 from left to right. The optimization process is similar to the above process and will not be repeated here. The stress distribution of the functional layer 11 corresponding to the upper, middle, and lower parts of the screen assembly 1 and the left, middle, and right sides is comprehensively adjusted to adjust the transverse cross-sectional area of ​​the transparent connection layer 12, further improving the utilization rate of the transparent connection layer 12 in buffering stress.

[0041] It should be noted that the transparent connection layer 12 is OCA (optical clear adhesive), and may also be other structures that can connect adjacent functional layers 11, and the present disclosure is not limited to this.

[0042] The present disclosure further proposes an electronic device, which includes: a device body and the above-mentioned screen assembly 1, and the screen assembly 1 is assembled to the device body.

[0043] Among them, the screen assembly 1 cooperates with each transparent connection layer 12 in a partial area of ​​the functional layer 11 to facilitate stress buffering and release, and the cooperation of each transparent connection layer 12 to form a complementary structure also avoids the interference of the transparent connection layer 12 on the display effect of the screen assembly 1, thereby improving the display effect, service life and user experience of the electronic device.

[0044] It should be noted that the electronic device may be a mobile phone, a computer, etc., and the present disclosure is not limited to this.
