[0007] Optionally, the orientation of the slope formed by the edge is consistent with the target bending direction of the display screen module.

[0008] Optionally,

[0009] The target bending direction is the direction from the back panel side of the electronic device to the front panel side;

[0010] Or, the target bending direction is the direction from the front panel side of the electronic device to the back panel side.

[0011] Optionally, the slope formed by the edge forms a preset angle with the plane where the display screen module is located, and the value of the preset angle is negatively correlated with the bendability of the display screen module.

[0033] Figure 1 Schematic three-dimensional structure diagram of an electronic device shown according to an exemplary embodiment. As Figure 1 shown, the electronic device 1 may include a display screen module 11 and a device frame 12. The device frame 12 wraps the edges of the display screen module 11 in the x-axis and y-axis directions, thereby assembling and fixing the display screen module 11.

[0034] In one embodiment, the display module 11 can adopt a flexible screen, enabling the display module 11 to be bent. For example, the electronic device 1 can be divided into a first part 1A and a second part 1B along an axis L, and the display module 11 can be bent around the axis L; wherein, assuming the target bending direction of the display module 11 is Figure 1 the negative direction of the z-axis in Figure 1 (i.e., the direction from the front panel side of the electronic device 1 to the back panel side, which is the direction from top to bottom), the display module 11 can be bent along the target bending direction until it forms a Figure 2 folded state as shown in Figure 2 , such that the first part 1A and the second part 1B are stacked in the z-axis direction. In the Figure 1 embodiment shown in Figure 1 , the axis L can be the perpendicular bisector of the long side of the display module 11 along the y-axis direction (the edge along the x-axis direction is the short side), which can reduce the size of the electronic device 1 in the y-axis direction to Figure 1 half of the unfolded state in Figure 1 ; of course, the axis L and the display module 11 can also have other relationships, and the present disclosure does not limit this.

[0035] In one embodiment, the display module 11 includes edges 111 and 112 as shown in Figure 1 Figure 1 , and both edges 111 - 112 are the short sides along the x-axis direction. In the technical solution of the present disclosure, structural improvements are made to the display module 11 and the device frame 12 at the edges 111 and 112 respectively to adapt to the bendable display module 11; for ease of understanding, the structures of the display module 11 and the device frame 12 at the edge 111 will be introduced in detail below.

[0036] Figure 3 is Figure 1 a partial cross-sectional view of the edge area of the electronic device shown in Figure 1 along the A - A direction. As shown in Figure 3 Figure 3 , the edge 111 on the display module 11 is in a slope shape, and the inner side wall of the device frame 12 (the side wall facing the display module 11) is recessed inward (recessed into the interior of the device frame 12 itself) to form a wedge-shaped groove 120 that fits the edge 111. Then, by inserting the edge 111 into the wedge-shaped groove 120, the assembly and fixation of the device frame 12 to the display module 11 can be achieved; wherein, an adhesive layer can be provided between the edge 111 and the wedge-shaped groove 120 to bond the edge 111 and the wedge-shaped groove 120, further enhancing the stability between the display module 11 and the device frame 12.

[0037] Among them, when the display module 11 is bent along the Figure 1 negative direction of the z-axis shown in Figure 1 , the display module 11 is at Figure 3The upper surface in [description] is more affected by the tension than the lower surface. Therefore, by setting the edge 111 to be ramp-shaped, with the orientation of the ramp being consistent with the target bending direction (both roughly from bottom to top), and forming a wedge-shaped groove 120 on the device frame 12 that fits the edge 111, the tension effect on the edge 111 can be reduced or even eliminated, avoiding the delamination (if there is an adhesive layer) or separation between the edge 111 and the wedge-shaped groove 120, which helps to improve the bonding strength between the display module 11 and the device frame 12.

[0038] Although Figure 1 the electronic device 1 in [description] can achieve the folding scenario as shown in Figure 2 , the present disclosure does not limit the bending angle; in fact, limited by the bendable condition of the display module 11 and the actual structure of the electronic device 1, smaller or larger bending angles can also be achieved. And in order to reduce or eliminate the tension effect caused by bending, taking Figure 3 as an example: Assume that the ramp formed by the edge 111 forms a preset angle α with the plane where the display module 11 is located. The value of this preset angle α in the related art is 90° (i.e., perpendicular), while in the present disclosure, the value of this preset angle α can be negatively correlated with the bendable degree of the display module 11, that is, when the bendable angle of the display module 11 is larger, the value of the preset angle α is smaller.

[0039] In one embodiment, although Figure 3 in the embodiment shown in Figure 4 , the ramp formed by the edge 111 is planar, and the wedge-shaped groove 120 has a planar inclined surface that fits the ramp, but the present disclosure does not limit the specific shape of the edge 111. For example, as shown in Figure 5 , the ramp formed by the edge 111 can be arc-shaped, and the wedge-shaped groove 120 has an arc-shaped inclined surface that fits the ramp; or for another example, as shown in

[0040] When the display module 11 is bent around the axis L, in addition to using the negative direction of the z-axis in Figure 1 as the target bending direction of the display module 11, the target bending direction can also be the positive direction of the z-axis in Figure 1 (that is, the direction from the back panel side of the electronic device 1 to the panel side, which is also the direction from bottom to top). The display module 11 can be bent along the target bending direction until it forms the folded state as shown in Figure 6 , so that the first part 1A and the second part 1B are stacked in the z-axis direction, and the display module 11 can be "enclosed" inside the electronic device 1.

[0041] Regarding Figure 6The illustrated embodiment Figure 7 is Figure 1 a partial cross-sectional view of the edge region of the illustrated electronic device along the A-A direction. When the display module 11 is bent in the positive direction of the z-axis as shown Figure 1 the lower surface of the display module 11 in Figure 7 is more affected by the tensile force than the upper surface. Therefore, by setting the edge 111 to be ramp-shaped, with the orientation of the ramp being consistent with the target bending direction (both roughly from top to bottom), and forming a wedge-shaped groove 120 on the device frame 12 that fits the edge 111, the tensile force effect on the edge 111 can be reduced or even eliminated, avoiding the glue opening (if there is an adhesive layer) or separation between the edge 111 and the wedge-shaped groove 120, which helps to improve the bonding strength between the display module 11 and the device frame 12. At the same time, the edge 111 can also adopt a curved surface similar to Figure 4 shown or Figure 5 a stepped inclined surface as shown, which will not be elaborated here.

[0042] In one embodiment, there is a black edge region at the edge of the display module 11. Taking Figure 7 as an example, there is an edge region corresponding to the black edge at the edge 111 of the display module 11; correspondingly, in the embodiment as shown in Figure 8 the edge region of the display module 11 corresponding to the black edge can be bent towards the backplane direction of the electronic device 1 (manifested as bending downwards in Figure 8 ). Thus, when the user observes the edge 111 of the display module 11 from top to bottom, the black edge region can be visually hidden, achieving a visually extremely narrow border effect. In addition to the edge 111, similar designs can also be adopted for other edges of the display module 11 in the x-axis and y-axis directions, which will not be elaborated here one by one; and Figure 8 the relevant structures for the extremely narrow border effect shown Figures 2 - 5 can also be applied to the embodiment as shown, and the present disclosure does not limit this.
