[0076] It is understood in this disclosure that any combination of features and / or embodiments disclosed in connection with FIGS. 2, 3, and 4 is conceived and included. Any combination of features described below in connection with FIGS. 2, 3, and 4 may be considered to be included in this disclosure as specific examples.

[0077] Referring to FIGS. 2, 3, and 4, a wearable electronic device (2) (e.g., the electronic device (101) of FIG. 1) may include a flexible display (also called a bendable display) (21) (e.g., the display module (160) of FIG. 1). When viewed in the unbended state of the wearable electronic device (2), the flexible display (21) may be a rectangular plate including, for example, a first edge (211), a second edge (212), a third edge (213), and a fourth edge (214). Looking at the unbended state of the wearable electronic device (2), the flexible display (21) may be provided (or formed) in a shape such that the distance between the first edge (211) and the second edge (212) is relative to the distance between the third edge (213) and the fourth edge (214). The unbended state of the wearable electronic device (2) can be understood as the flexible display (21) being substantially flat. The bent state of the wearable electronic device (2) can be understood as the flexible display (21) being bent.

[0078] According to various embodiments, the wearable electronic device (2) may include a bendable structure (also referred to as a bendable frame) (22) configured to support the back surface of a flexible display (21). The bendable structure (22) may be configured to be bendable so as to be worn on a user's body, such as a finger or wrist. The bendable structure (22) may be configured, for example, so that the wearable electronic device (2) can be bent at various radii of curvature. For example, FIG. 3 shows a bent state in which the wearable electronic device (2) is bent at a first radius of curvature, and FIG. 4 shows a bent state in which the wearable electronic device (2) is bent at a second radius of curvature larger than the first radius of curvature. The wearable electronic device (2) can be bent at various radii of curvature to fit the size of the user's body (e.g., finger) and worn on the user's body. It can be understood that the wearable electronic device (2) is not restricted to bending with a constant radius of curvature as in FIG. 3 or 4, and that the wearable electronic device (2) is configured to be bent into a rounded shape that wraps around the user's body (e.g., fingers or wrist) through a bendable structure (22).

[0079] According to various embodiments, the bendable structure (22) may include first to 16 support members (301, ..., 316)) connected in sequence. The first to 16 support members (301, ..., 316)) may be arranged in a direction extending from the first edge (211) of the flexible display (21) to the second edge (212). The bendable structure (22) may have flexibility through the boundaries (or connections) between the first to 16 support members (301, ..., 316)). The boundaries between the first to 16 support members (301, ..., 316)) may be configured to have the property that the bendable structure (22) does not return to its pre-deformation state even after the force is removed following deformation caused by the force. In various embodiments, although not separately illustrated, the boundaries (or connections) between the first to sixteenth support members (301, ..., 316)) may be configured such that, through friction between mechanical components such as links, the bendable structure (22) does not return to its pre-deformed state even after the force is removed following deformation. There may be various other ways in which the bendable structure (22) is configured to have the property of not returning to its pre-deformed state even after the force is removed following deformation. The number of multiple support members included in the bendable structure (22) is not limited to the illustrated examples. The first support member (301) may include a partial upper surface (e.g., the partial upper surface (301A) of FIG. 5). The partial upper surface of the first support member (301) may be coupled to the back surface of the flexible display (21) and configured to support the back surface of the flexible display (21). The first support member (301) may include a partial lower surface (e.g., the partial lower surface (301B) of FIG. 7) facing in the opposite direction to the partial upper surface.When the wearable electronic device (2) in a bent state is worn on the user's body (e.g., finger or wrist), a partial lower surface of the first support (301) may be configured to face at least partially with the user's body and be supported by the user's body. The partial lower surface of the first support (301) may improve contact with the user's body when the wearable electronic device (2) in a bent state is worn on the user's body. The first support (301) may have a thickness corresponding to the distance between the third edge (213) and the fourth edge (214) in a direction toward the third edge (213) of the flexible display (21) to the fourth edge (214) (or a direction parallel to the first edge (211) or the second edge (212) of the flexible display (21). The first support member (301) may have a shape (e.g., cross-sectional shape) that narrows in the direction from the partial upper surface to the partial lower surface. When viewed in the direction from the third edge (213) to the fourth edge (214) of the flexible display (21) (or in a direction parallel to the first edge (211) or the second edge (212) of the flexible display (21)), the first support member (301) may be provided (or formed) in a trapezoidal shape. The remaining second to sixteenth support members (32,…, 316) may be provided (or formed) in a shape substantially identical to or at least partially similar to the first support member (301). The bendable structure (22) may include a plurality of partial upper surfaces formed by the first to 16 support members (301, ..., 316), and the plurality of partial upper surfaces may be understood as display support surfaces. The flexible display (21) may be placed or bonded to the display support surface through an adhesive material (or adhesive material) (e.g., adhesive material (8) of FIG. 9) placed between the back surface of the flexible display (21) and the display support surface of the bendable structure (22).The bendable structure (22) may include a plurality of lower upper surfaces formed by the first to 16th support members (301,…, 316), and the plurality of lower upper surfaces may be understood as body support surfaces for the user's body when the wearable electronic device (2) in a bent state is worn on the user's body. The trapezoidal shape of the first to 16th support members (301,…, 316)) can improve the bendable structure (22) so that it can be bent with a smaller radius of curvature.

[0080] According to various embodiments, the bendable structure (22) may include a plurality of holes provided (or formed) at the boundaries (or connections) between the first to 16 support members (301, ..., 316)) (e.g., a hole (320) formed at the boundary between the first support member (301) and the second support member (302). The plurality of holes may be openings penetrating the bendable structure (22) in a direction toward the third edge (213) of the flexible display (21) toward the fourth edge (214) (or a direction parallel to the first edge (211) or the second edge (212) of the flexible display (21). The plurality of holes may improve the bendability of the bendable structure (22).

[0081] According to various embodiments, the bendable structure (22) may be provided (or formed) as an integrated or single structure (e.g., a single continuous structure or a complete structure).

[0082] According to various embodiments, although not separately illustrated, the bendable structure (22) may not be limited to the examples of FIGS. 2, 3, and 4. For example, the bendable structure (22) may be provided in the form of a plate (e.g., a flexible plate) comprising a display support surface and a body support surface, replacing a plurality of support members (e.g., first to sixth support members (301,…, 316)). The bendable structure (22) may be implemented so that it does not substantially return to its pre-deformation shape even after the force is removed, after being deformed by receiving a force.

[0083] According to various embodiments, the bendable structure (22) may be formed of a metallic material and / or a non-metallic material.
