Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the related art, the folding screen comprises functional layers such as a substrate layer, a polarizing layer, a touch layer and a cover plate layer, and a complete screen assembly is formed by bonding multiple functional layers through adhesive layers. When the folded screen is bent, the bending area of the functional layer is bent and deformed, and then stress which may cause damage and fracture is generated. At this moment, the glue film between the adjacent functional layers can relieve stress to a certain extent, but the monoblock size of matching in the functional layer is great, has increased the release degree of difficulty of glue film stress, reduces the glue film size simply and causes the influence to the whole display effect of screen subassembly again.

Fig. 1 is a schematic cross-sectional structural view of a screen assembly in an exemplary embodiment of the present disclosure. As shown in fig. 1, the screen assembly 1 includes: a plurality of functional layers 11 and at least two transparent tie layers 12. The functional layers 11 include bending portions 111, and when the screen assembly 1 is bent, the bending portion 111 of each functional layer 11 is deformed correspondingly. The transparent connecting layer 12 is disposed between two adjacent functional layers 11 and is connected to two adjacent functional layers 11, respectively, so that the adjacent functional layers 11 are assembled and matched. Wherein, each transparent connecting layer 12 is matched with a partial area of the corresponding functional layer 11, the longitudinal projection of all the transparent connecting layers 12 is matched with the longitudinal projection of the functional layer 11, and the longitudinal projections of any two transparent connecting layers 12 are not overlapped with each other.

Each transparent connecting layer 12 fitted to a partial region of the functional layer 11 facilitates the buffering and release of stress, and the transparent connecting layers 12 fitted to form a complementary structure also prevents the transparent connecting layers 12 from interfering with the display effect of the screen assembly 1.

In the above embodiment, at least a portion of each transparent connection layer 12 is fitted to the bending portion 111, so that each transparent connection layer 12 can independently buffer the stress of the functional layer 11, and the buffering efficiency is improved.

The present disclosure does not limit the number of the functional layers 11 and the transparent connecting layers 12 disposed between adjacent functional layers 11, and the following takes three functional layers 11 and two transparent connecting layers 12 as an example, and the structure of the transparent connecting layers 12 is exemplarily described:

the transparent connecting layer 12 is a continuous structure, the continuous transparent connecting layer 12 is matched with a partial area of the functional layer 11, and when the functional layer 11 deforms due to bending of the screen assembly 1, the continuous transparent connecting layer 12 implements stress buffering for the functional layers 11 corresponding to the partial projection area. The transparent connecting layer 12 corresponding to the other region of the functional layer 11 performs stress buffering for the plurality of functional layers 11 corresponding to the other partial projection region. The continuous transparent connecting layer 12 has a simple structure and low molding cost.

FIG. 2 is a schematic structural diagram of one functional layer 11 and a corresponding transparent tie layer 12 in an exemplary embodiment of the present disclosure; FIG. 3 is a schematic structural diagram of another functional layer 11 and a corresponding transparent tie layer 12 in an exemplary embodiment of the present disclosure; fig. 4 is a schematic view of the structure of the functional layer 11 and the transparent connecting layer 12 in fig. 2 and 3. As shown in fig. 2, 3 and 4, the transparent connection layer 12 includes a plurality of connection portions 121 disposed at intervals. Above-mentioned structure sets up and makes there is the clearance between two arbitrary connecting portion 121, takes place to buckle when screen pack 1, and transparent articulamentum 12 produces stress after, every connecting portion 121 can both utilize above-mentioned clearance to take place deformation in order to release stress, has promoted stress release efficiency, has also reduced the degree of difficulty of transparent articulamentum 12 release stress. And from the perspective of the whole screen assembly 1, the connecting portions 121 of the transparent connecting layers 12 of the upper and lower layers form a complementary structure, so that the display interference of the transparent connecting layers 12 on the screen assembly 1 is avoided.

In the above embodiments, the transverse cross section of the connecting portion 121 may be rectangular, trapezoidal, polygonal, or a shape with an arc-shaped edge, etc., and the disclosure is not limited thereto. When the transverse cross-section of the connecting portion 121 includes an arc-shaped edge, the arc-shaped edge can be used to enable the transparent connecting layer 12 to have smooth absorption and release capabilities for stress, so that it can be effectively matched to stress variations in different regions of the functional layer 11. When the transverse cross section of the connecting portion 121 is rectangular, the connecting portions 121 may be arranged in an array along the extending direction of the bending portion 111 of the functional layer 11, so as to reduce the molding difficulty of the transparent connecting layer 12, and facilitate the matching of the upper and lower positions between the transparent connecting layers 12.

It should be noted that the widths of the spaces between adjacent connecting portions 121 may be equal to facilitate the position correspondence of the upper and lower connecting portions 121 and the formation of the connecting portions 121; alternatively, the width of the space between adjacent connecting portions 121 may be different so that the space 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 gap width may be reduced to improve the buffering capacity of the connection portion 121 for the stress in the region.

In addition, the structures of any two connection parts 121 may be the same, and there may be a difference in the structures of the two connection parts 121, which is not limited by the present disclosure. When the structures of any two connecting parts 121 are the same, on one hand, the molding cost of the transparent connecting layer 12 is reduced, on the other hand, the matching between the projections of all the transparent connecting layers 12 is facilitated, and the influence of the transparent connecting layers 12 on the display effect of the screen assembly 1 is reduced. When there are two connecting portions 121 with different structures, the structures of the connecting portions 121 may be set for different stresses in different regions of the functional layer 11, so as to improve the buffering efficiency of the stresses.

In order to give different levels of stress buffering for different areas of the screen assembly 1 with respect to their degree of deformation, the transverse cross-sectional area of the transparent connecting layer 12 may also be optimized:

in an embodiment, the functional layer 11 includes a bending portion 111 and an extending portion connected to the bending portion 111, when the screen assembly 1 is bent, the bending portion 111 is deformed greatly, and the extending portion cooperates with the bending portion 111 to be deformed less. At this time, the transparent connection layer 12 corresponding to the bending portion 111 generates a large stress buffering effect, thereby improving the utilization rate of the transparent connection layer 12.

For example, the rectangular screen assembly 1 is divided into three regions, i.e., an upper region, a middle region and a lower region, wherein the middle region is a 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 portion of the screen assembly 1 is bent, so that the bent portion 111 of the functional layer 11 is largely deformed, and the other regions of the functional layer 11 are adaptively deformed smaller than the bent portion 111. The stress distribution corresponding to the deformation of the functional layer 11 from the upper part to the middle part is changed in a linear increasing way. Therefore, as shown in fig. 5, the transverse cross-sectional area of the transparent connection layer 12 can be linearly increased from the extending 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 is gradually increased, and the buffering effect for the stress is increased to the maximum from the edge of the extending portion to the central line of the bending portion 111, thereby increasing the utilization rate of the transparent connection layer 12 in terms of buffering the stress.

In addition, the screen assembly 1 can be divided into three areas, namely a left area, a middle area and a right area, deformation of the functional layer 11 corresponding to the three areas is analyzed to obtain a corresponding stress change area, so that the distribution of the transverse cross section area of the transparent connecting layer 12 from left to right is optimized, the optimization process is similar to the process, and the description is omitted here. Synthesize screen assembly 1 upper portion, middle part and lower part and left side, middle and right side corresponding functional layer 11's stress distribution and adjust the horizontal cross sectional area of transparent connecting layer 12, further promote the utilization ratio of transparent connecting layer 12 in the aspect of the buffering stress.

The transparent connecting layer 12 may be an OCA (optical clear adhesive tape), or may be another structure capable of connecting adjacent functional layers 11, and the present disclosure is not limited thereto.

The present disclosure further proposes an electronic device, comprising: the device body and the screen assembly 1, the screen assembly 1 is assembled to the device body.

The screen assembly 1 is matched with each transparent connecting layer 12 in the functional layer 11 partial area, so that stress buffering and releasing are facilitated, and the transparent connecting layers 12 are matched to form a complementary structure, so that interference of the transparent connecting layers 12 on the display effect of the screen assembly 1 is avoided, and the display effect, the service life and the user experience of the electronic equipment are improved.

It should be noted that the electronic device may be a mobile phone, a computer, etc., and the disclosure is not limited thereto.
