Fig. 1 is a schematic partial cross-sectional view of an electronic device 100 in the related art, and as shown in fig. 1, the electronic device 100 may include a flexible display layer 101, a housing 102, a first adhesive layer 103, a first flexible cover 104, a second adhesive layer 105, and a second flexible cover 106. The flexible display layer 101 may be connected to the first flexible cover plate 104 through a first adhesive layer 103, and the first flexible cover plate 104 may be connected to the second flexible cover plate 106 through a second adhesive layer 105. In this way, a double-layer cover plate layer can be formed by the first flexible cover plate 104 and the second flexible cover plate 106, thereby increasing the thickness and strength, and thus the flatness of the second flexible cover plate 106 forming the surface of the electronic device 100 can be improved. However, in this related art, since a double-layered flexible cover plate is provided, the thickness is increased, thereby increasing the difficulty of folding the electronic device 100, and the increase in thickness also reduces the folding fatigue limit of the display panel.
Accordingly, the present application provides an electronic device 200 as shown in fig. 2 and 3, the electronic device 200 may include a flexible display panel 1 and a middle frame 2, and the flexible display panel 1 may include a flexible display layer 11 and a flexible cover sheet layer 12 bonded to the flexible display layer 11. The middle frame 2 may include a bottom wall 21, a plurality of side walls 22, and a receiving cavity 23, the bottom wall 21 and the plurality of side walls 22 may enclose the receiving cavity 23, the flexible display layer 11 may be disposed within the receiving cavity 23, and the flexible cover layer 12 may be disposed in a stack with the side walls 22. The flexible cover plate layer 12 may include a PI (polyimide film) film layer, and because the flexible cover plate layer 12 has larger flexibility and smaller strength, and is very prone to be uneven, as shown in fig. 3, the electronic device 200 may further include a reinforcing layer 3, where the reinforcing layer 3 may be disposed between the side wall 22 and the flexible cover plate layer 12, so that a certain support may be provided for the flexible cover plate layer 12 by the reinforcing layer 3, and wrinkles and unevenness of the flexible cover plate layer 12 may be reduced, and because the reinforcing layer 3 is disposed only between the side wall 22 and the flexible cover plate layer 12, its area may be far smaller than the whole area of the flexible cover plate layer 12, so that the thickness of the middle area of the flexible cover plate layer 12 may not be increased, which is beneficial to realizing folding of the flexible display panel 1.
Wherein the thickness of the stiffening layer 3 may be greater than or equal to 0.04mm and less than or equal to 0.3mm, for example, the thickness of the stiffening layer 3 may be equal to 0.05mm, or 0.06mm, or 0.1mm, or 0.15mm, which may be specifically selected according to practical situations, and by limiting the thickness of the stiffening layer 3, it may be avoided that the stiffening layer 3 is too thin to play a supporting role, while it may be avoided that the stiffening layer 3 is too thick to increase the overall thickness of the electronic device 200. The reinforcing layer 3 may include one or more of a glass fiber layer, a kevlar fiber layer, a carbon fiber layer, a boron fiber layer, and a steel sheet layer, which is not limited by the present disclosure.
Further, in order to improve the bending performance of the flexible display panel 1, the surface of the flexible cover plate layer 12 facing the outside of the electronic device 200, or the surface of the flexible cover plate layer 12 facing the inside of the electronic device 200 may be designed as a neutral layer of the electronic device 200, so that when the electronic device 200 is bent, the structural layers of the flexible display panel 1, which are located on the side of the flexible cover plate layer 12 facing the inside of the electronic device 200, are compressed, and the probability of unrecoverable deformation of the structural layers due to stretching is reduced.
As shown in fig. 3, the reinforcing layer 3 may be disposed on a surface of the side wall 22 away from the bottom wall 21 in a stacked manner, or in other embodiments, as shown in fig. 4, the side wall 22 may include a step portion 221, where the step portion 221 may be formed by recessing from a surface of the side wall 22 away from the bottom wall 21 with respect to the bottom wall 21, and the reinforcing layer 3 may be disposed in the step portion 221, so that compared with the technical solution shown in fig. 1, the technical solution of fig. 4 is beneficial to reduce the overall thickness of the electronic device 200, and accords with the trend of light and thin development of the electronic device 200. Still referring to fig. 4, the flexible cover plate layer 12 may be received in the step 221, and the flexible cover plate layer 12 may be flush with the surface of the side wall 22 away from the bottom wall 21, so as to improve the aesthetic appearance, and the thickness of the electronic device 200 may be further reduced by the arrangement that the reinforcement layer 3 is received in the step 221, while being located outside the step 221 with respect to the flexible cover plate layer 12.
In an embodiment, the flexible cover sheet layer 12 may include a first side edge 121, and the first side edge 121 may be disposed flush with the flexible display layer 11. The sidewall 22 may include a first sidewall 222, the first sidewall 222 may include a stepped portion 221, both the first side edge 121 and a portion where the flexible display layer 11 and the first side edge 121 are laminated may extend into the stepped portion 221, and the reinforcing layer 3 may include a first reinforcing layer 31, and the first reinforcing layer 31 may be disposed between the stepped portion 221 and the flexible display layer 11, and may be strength-reinforced by the first reinforcing layer 31 on one hand and may support the flexible display layer 11 by the first reinforcing layer 31 on the other hand.
In another embodiment, as shown in fig. 5, the flexible cover layer 12 may include a second side edge 122, the second side edge 122 may protrude from a corresponding side edge of the flexible display layer 11, the flexible display panel 1 may further include a polarizer 18, the polarizer 18 is disposed between the flexible cover layer 12 and the flexible display layer 11, and the polarizer 18 protrudes from a side of the flexible display layer 11 corresponding to the second side edge 122, the side wall 22 may further include a second side wall 223, the second side wall 223 includes a step 221, a portion of the second side edge 122 of the flexible cover layer 12 and the polarizer 18 corresponding to the second side edge 122 may protrude into the step 221, the reinforcing layer 3 may include a second reinforcing layer 32 disposed between the polarizer 18 and the step 221, and compared to the embodiment shown in fig. 4, the strength of the flexible cover layer 12 is enhanced, and at the same time, since the flexible display layer 11 may be relatively far from the second side wall 223, damage to the flexible display layer 11 may be reduced, which is beneficial for improving the yield of the assembly process, and in case of the electronic device 100 may also reduce the risk of damage to the flexible display layer 11 due to impact.
In fact, in the embodiments of fig. 4 and 5, a third side wall 224 may be included, respectively, the flexible cover layer 12 may extend towards the third side wall 224 and protrude from the flexible display layer 11, and the flexible cover layer 12 may cover the surface of the third side wall 224 remote from the bottom wall 21, and the stiffening layer 3 may include a third stiffening layer 33 arranged between the third side wall 224 and the flexible cover layer 12.

Specifically, since the flexible cover sheet layer 12 extends toward the third sidewall 224 and protrudes from the flexible display layer 11, a relief space may be formed by the portion of the flexible cover sheet layer 12 protruding from the flexible display layer 11 and the flexible display layer 11, so that the flexible circuit board 13 may be bent from the flexible display layer 11 toward the side edge of the third sidewall 224 in a direction away from the flexible cover sheet layer 12, thereby covering the flexible circuit board 13 by the flexible cover sheet layer 12 and improving the aesthetic appearance. The third sidewall 224 may be located at the bottom, top, or may be a side of the electronic device 200, which is not limited by the present disclosure.
