Fig. 1 is a schematic perspective view of an electronic device according to an exemplary embodiment. As shown in fig. 1, the electronic device 1 may include a display module 11 and a device bezel 12, where the device bezel 12 wraps edges of the display module 11 in x-axis and y-axis directions, thereby assembling and fixing the display module 11.

In an embodiment, the display module 11 may use a flexible screen, so that the display module 11 may be bent. For example, the electronic device 1 may be divided into a first portion 1A and a second portion 1B along an axis L, and the display module 11 may be bent around the axis L, where, assuming that a target bending direction of the display module 11 is a negative direction of the z-axis in fig. 1 (i.e., a direction from the panel side toward the back panel side of the electronic device 1, i.e., a direction from top to bottom), the display module 11 may be bent along the target bending direction until a folded-in-half state as shown in fig. 2 is formed, so that the first portion 1A and the second portion 1B are stacked in the z-axis direction. In the embodiment shown in fig. 1, the axis L may be a perpendicular bisector of a long side of the display screen module 11 along the y-axis direction (an edge along the x-axis direction is a short side), so that the size of the electronic device 1 along the y-axis direction may be reduced to half of the unfolded state in fig. 1, and of course, the axis L and the display screen module 11 may also have other relationships, which is not limited by the disclosure.

In one embodiment, the display module 11 includes an edge 111 and an edge 112 as shown in fig. 1, where the edges 111-112 are all the short sides along the x-axis. In the technical scheme of the disclosure, the structures of the display screen module 11 and the equipment frame 12 at the edge 111 and the edge 112 are improved respectively to adapt to the bendable display screen module 11, and the structures of the display screen module 11 and the equipment frame 12 at the edge 111 are described in detail for the sake of understanding.

Fig. 3 is a partial cross-sectional view of an edge region of the electronic device shown in fig. 1, taken along A-A. As shown in fig. 3, the edge 111 on the display module 11 is sloped, and the inner side wall (the side wall facing the display module 11) of the device frame 12 is recessed inward (the inner side of the device frame 12 is recessed) to form a wedge-shaped groove 120 matching with the edge 111. Then, the edge 111 is inserted into the wedge-shaped groove 120, so that the device frame 12 can be assembled and fixed to the display screen module 11, wherein an adhesive layer can be further arranged between the edge 111 and the wedge-shaped groove 120, so that the edge 111 and the wedge-shaped groove 120 are bonded, and the stability between the display screen module 11 and the device frame 12 is further improved.

When the display screen module 11 is bent along the negative direction of the z-axis shown in fig. 1, the tension influence on the upper surface of the display screen module 11 in fig. 3 is greater than that on the lower surface, so that by setting the edge 111 to be slope-shaped, the slope direction is consistent with the target bending direction (all are approximately from bottom to top), and forming the wedge-shaped groove 120 matched with the edge 111 on the device frame 12, the tension influence on the edge 111 can be reduced or even eliminated, the glue opening (if an adhesive layer exists) or separation between the edge 111 and the wedge-shaped groove 120 is avoided, and the bonding strength between the display screen module 11 and the device frame 12 is improved.

Although the electronic device 1 in fig. 1 may implement a folding scene as shown in fig. 2, the present disclosure does not limit the folding angle, and in practice, may implement a smaller or larger folding angle due to the bendable state of the display screen module 11 and the actual structure of the electronic device 1. In order to reduce or eliminate the tension effect caused by bending, taking fig. 3 as an example, assume that a slope formed by the edge 111 forms a preset angle α with a plane where the display screen module 11 is located, where the preset angle α has a value of 90 ° (i.e. vertical) in the related art, and the value of the preset angle α in the present disclosure may be inversely related to the bendable degree of the display screen module 11, i.e. the larger the bendable angle of the display screen module 11, the smaller the value of the preset angle α.

In one embodiment, although the ramp formed by the rim 111 is planar in the embodiment shown in fig. 3, the wedge-shaped recess 120 is provided with a planar sloped surface that mates with the ramp, the specific shape of the rim 111 is not limited by the present disclosure. For example, as shown in fig. 4, the slope formed by the edge 111 may be curved, and the wedge-shaped groove 120 is provided with a curved inclined surface that fits to the slope, and for example, as shown in fig. 5, the slope formed by the edge 111 may be stepped, and the wedge-shaped groove 120 is provided with a stepped inclined surface that fits to the slope.

When the display screen module 11 is bent around the axis L, the target bending direction of the display screen module 11 may be a positive direction of the z-axis in fig. 1 (i.e., a direction from the back plate side to the panel side of the electronic device 1, i.e., a downward-upward direction) in addition to the negative direction of the z-axis in fig. 1, and the display screen module 11 may be bent along the target bending direction until a folded state as shown in fig. 6 is formed, so that the first portion 1A and the second portion 1B are stacked in the z-axis direction, and the display screen module 11 may be "closed" inside the electronic device 1.

For the embodiment shown in fig. 6, fig. 7 is a partial cross-sectional view of the edge region of the electronic device shown in fig. 1 along the A-A direction. When the display screen module 11 is bent along the positive direction of the z-axis shown in fig. 1, the lower surface of the display screen module 11 in fig. 7 is more affected by the tension than the upper surface, so that by setting the edge 111 to be slope-shaped, the slope direction is consistent with the target bending direction (both being approximately from up to down), and forming the wedge-shaped groove 120 matched with the edge 111 on the device frame 12, the tension influence on the edge 111 can be reduced or even eliminated, the glue opening (if an adhesive layer exists) or separation between the edge 111 and the wedge-shaped groove 120 is avoided, and the bonding strength between the display screen module 11 and the device frame 12 is improved. Meanwhile, the edge 111 may also have a cambered surface shape similar to that shown in fig. 4 or a stepped inclined surface as shown in fig. 5, which will not be described herein.

In one embodiment, the display module 11 has a black border area at the border. Taking fig. 7 as an example, the display screen module 11 has an edge area corresponding to a black edge at the edge 111, and correspondingly, in the embodiment shown in fig. 8, the edge area corresponding to the black edge on the display screen module 11 may be bent towards the back panel of the electronic device 1 (as shown by bending downwards in fig. 8), so that when a user views the edge 111 of the display screen module 11 from top to bottom, the black edge area may be hidden visually, and a very narrow frame effect is achieved visually. In addition to the edge 111, other edges of the display screen module 11 in the x-axis and y-axis directions may be designed similarly, which will not be described in detail herein, and the related structure of the extremely narrow frame effect shown in fig. 8 may also be applied to the embodiments shown in fig. 2-5, which is not limited by the disclosure.

Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This application is intended to cover any adaptations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.
