A folded screen assembly and an electronic device provided according to an embodiment of the present application are described below with reference to fig. 1 to 9.
The present embodiment provides a foldable screen assembly, which comprises a display main body 102, a transparent cover plate 104, a tensioning device 108 and a heating element 110, wherein the display main body 102 is connected to the transparent cover plate 104 through an adhesive layer 106, the transparent cover plate 104 serves as an outer screen to protect the display main body 102, and the display effect of the display main body 102 can be better improved by selecting different materials. For the display main body 102, the display main body mainly includes a folding portion 1022 and a display portion 1024 connected to each other, when the display main body is folded, the folding portion 1022 is bent, so that the display portion 1024 connected to the folding portion 1022 rotates accordingly, when the display portions 1024 on both sides are attached to each other, the folding screen assembly can be considered to be folded in place, and when the display portions 1024 on both sides are coplanar, the folding screen assembly can be considered to be unfolded in place, it can be understood that the display main body 102 itself includes a plurality of pixel points 1026, so as to display contents to be displayed. On the basis that the display main body 102 is folded, in order to ensure the display effect of folding to different degrees, a tensioning device 108 connected with one end or two ends of the display main body is further arranged, and under the action of the tensioning device 108, the display main body can be in different folding degrees, the flatness of the display surface is ensured, and the display effect of the interface is further improved.
It should be emphasized that when the display main body 102 is folded for too many times, a crease is inevitably generated, the crease is generated due to creep deformation of the cured adhesive layer 106 after being folded for many times, in the present application, the heating element 110 is directly arranged in the adhesive layer 106, so that the state of the cured adhesive layer 106 can be changed by heating, the specific position is molten, and in the molten state, the adhesive layer 106 has certain fluidity, and can be gradually refilled between the display main body 102 and the transparent cover plate 104, so as to recover the original use experience of the product, and greatly improve the use experience of the product.
Further, the Adhesive layer 106 may be an Optical Clear Adhesive (OCA), which is generally in a liquid state and can be cured to be converted into a solid state under specific illumination.
In addition, whether the heating element 110 is heated or not only needs to be controlled by electrifying, so that a user can repair the foldable screen assembly by himself or herself in the using process, and the using convenience is greatly improved.
In order to reduce the influence on the interface display of the display main body 102, the adhesive layer 106 may be selected to be fully transparent or semi-transparent, and it can be understood that when the adhesive layer 106 is selected to be fully transparent, the influence on the interface display effect of the display main body 102 is the lowest.
The adhesive layer 106 is required to be disposed between the display body 102 and the transparent cover plate 104 in order to connect the display body 102 and the transparent cover plate 104.

The heating element 110 mainly includes a plurality of first heating lines 1102, and by limiting the extension of the first heating lines 1102 along the folding line direction, a certain amount of heat can be generated when power is applied, and the adhesive layer 106 can change its state after being heated, and since the position of the folding line is generally along the axis of the rotating shaft during folding, the heating element 110 can heat the adhesive layer 106 on the left and right sides of the extension direction after power is applied, so that the adhesive layer is changed into a flowing molten state.
It can be understood that when the first heating line 1102 is folded, the position of the fold is the position where the variation of the adhesive layer 106 is the largest, so that the fold can be repaired greatly by directly extending the first heating line 1102 along the direction of the fold, and the flatness of the display main body is ensured.
Further, the interval between any two adjacent first heating wires 1102 among the plurality of first heating wires 1102 is proportional to the distance of the first heating wires 1102 from the folded part 1022.
Since the plurality of first heater lines 1102 are arranged in the adhesive layer 106, and the position where the folding is generated is generally located in the folding portion 1022, that is, the area where the folding deformation is largest, when the first heater lines 1102 are disposed, the distance between the two first heater lines 1102 gradually increases from the folding portion 1022 to the display portion 1024, in other words, the distance in the folding portion 1022 is smallest, the arrangement of the first heater lines 1102 is the most dense, and the arrangement of the first heater lines 1102 is more sparse at the position farther from the folding portion 1022.
