Description

An electronic device comprising a structure for bending an end of a display

[0001] Various embodiments disclosed in this document relate to an electronic device including a structure for bending an end portion of a display.

[0002] Advances in display technology have led to the development of electronic devices that can be transformed into various shapes. For example, a foldable electronic device can be provided that operates by folding or unfolding two housings. The foldable electronic device may include a display that can fold together in response to the folding motion of the two housings. Meanwhile, since the electrical components are placed in each of the two housings, an electrical structure may be required to connect the electrical components.

[0003] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above-described matters constitute prior art related to the present disclosure.

[0004] A foldable electronic device may include a hinge device, and a first housing and a second housing that are connected to each other in opposite directions through the hinge device. The foldable electronic device may be operated in an in-folding manner and / or an out-folding manner by allowing the first housing to rotate with respect to the second housing through the hinge device (e.g., a hinge module, a hinge structure, or a hinge assembly) in a range of 0 degrees to 360 degrees. The foldable electronic device may include a display that is arranged to be at least partially supported by the first housing and the second housing when in an unfolded state. The display may include a folding area that is deformed in response to a folding or unfolding operation of the foldable electronic device. The display may include a plurality of layers (e.g., a window layer, a POL, a polymer layer, or a functional layer) arranged on an upper surface and / or a lower surface with respect to an electronic display panel.

[0005] The plurality of layers constituting the display may be arranged separately in the first housing and the second housing to prevent plastic deformation from occurring in the folding region of the display. For example, any one of the plurality of layers may be arranged separately in the first housing and the second housing with respect to the folding axis. For example, layers including metal components (e.g., a support plate, a reinforcing plate, a digitizer panel) may be arranged separately in the first housing and the second housing because plastic deformation may occur when bent.

[0006] However, since the layers constituting the display are arranged separately in the first housing and the second housing, a gap may occur in the folding area. The larger the gap between the layers arranged in the first housing and the layers arranged in the second housing in the folding area, the more the durability of the folding area may be weakened. For example, when an external force is applied between the gaps, the display may be damaged due to insufficient support area.

[0007] Meanwhile, the display may include a digitizer panel. The digitizer panel may be disposed separately in the first housing and the second housing to prevent plastic deformation. As described above, since the digitizer panel is disposed separately in the first housing and the second housing, a gap may occur in the folding area. The larger the gap between the digitizer panels, the lower the recognition rate of the stylus pen in the folding area.

[0008] As described above, when the gap between the layer disposed in the first housing and the layer disposed in the second housing is reduced in the folding area, when the foldable electronic device is folded, the mechanism located at the bottom of the display and the end of the layer disposed separately in the first and second housings may come into contact, causing deformation. When the thickness of the foldable electronic device is increased, the mechanism located at the bottom of the display and the end of the layer disposed separately in the first and second housings may not come into contact, but the aesthetic appeal of the foldable electronic device may be reduced.

[0009] The technical tasks to be achieved in this document are not limited to the technical tasks mentioned above, and other technical tasks not mentioned will be clearly understood by those with ordinary skill in the technical field to which this document pertains from the description below.

[0010] According to one embodiment of the present disclosure, an electronic device may include a foldable housing including a first housing and a second housing rotatably connected to the first housing about a folding axis. The electronic device may include a display including a first plate, at least a portion of which is disposed on the first housing, a second plate, at least a portion of which is disposed on the second housing, and a folding area deformed in response to a rotational motion of the first housing and the second housing. The electronic device may include a bending member disposed between the foldable housing and the display, the bending member supporting an end portion of the first plate and an end portion of the second plate based on the rotation of the first housing and the second housing. The bending member may include a base layer including a deformable portion deformed in response to the rotational motion of the first housing and the second housing, at least a portion of which corresponds to the folding area.

[0011] According to one embodiment disclosed in the present document, a bending member disposed between a display and a housing can press and bend an end portion of a layer constituting a display separately disposed in a first housing and a second housing when the electronic device is folded. Accordingly, even if the gap between the layer disposed in the first housing and the layer disposed in the second housing is reduced, the end portion of the layer constituting the display may not come into contact with a mechanism disposed under the display. Accordingly, by reducing the gap between one layer of the display separately disposed in the first housing and the second housing while maintaining the thickness of the electronic device, the durability of the display in the folding area can be enhanced.

[0012] Additionally, the recognition rate of the stylus pen in the folding area can be improved as the gap between the digitizer panels arranged separately in the first housing and the second housing is reduced.

[0013] The effects that can be obtained from the present disclosure are not limited to the effects mentioned above, and other effects that are not mentioned can be clearly understood by a person having ordinary skill in the art to which the present disclosure belongs from the description below.

The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0054] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna.

Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service.

[0094] FIG. 5 is an exploded perspective view of a display (400) according to one embodiment disclosed in this document.

[0095] The display (400) of FIG. 5 may be an example of the first display described above in FIG. 2A and FIG. 4 (e.g., the first display (230) of FIG. 2A and FIG. 4).

[0096] The display (400) according to exemplary embodiments of the present disclosure may include an unbreakable (UB) type OLED display (e.g., a curved display). However, the present invention is not limited thereto, and the display (400) may also include a flat type display of an on-cell touch AMOLED (active matrix organic light-emitting diode) (OCTA) type.

[0097] Referring to FIG. 5, the display (400) may include a window layer (410), a polarizing layer (POL) (420) (e.g., a polarizing film) sequentially disposed on the back surface (e.g., the -z-axis direction of FIG. 4) of the window layer (410), a display panel (430), a polymer layer (440), a support plate (450), and reinforcing plates (461, 462). In some embodiments, the display (400) may include a damping layer disposed between the window layer (410) and the display panel (430) instead of the polarizing layer (420). Additionally, in some embodiments, the damping layer may be disposed on or below the polarizing layer (420).

[0098] In one embodiment, the display (400) may include a digitizer panel (470) positioned below the support plate (450). In one embodiment, the display (400) may also include a digitizer panel (470) positioned between the support plate (450) and the reinforcing plates (461, 462). In one embodiment, the digitizer panel (470) may be positioned between the polymer layer (440) and the support plate (450). For example, if the display (400) is a POL-less display, the polarizing layer may be omitted, and a transparent reinforcing layer (e.g., a buffer layer) may be further positioned therein. In some embodiments, the reinforcing plate (460) (e.g., the first reinforcing plate (461) and the second reinforcing plate (462)) may be omitted.

[0099] Although not shown in the drawing, in one embodiment, a buffer member (not shown) may be placed between the window layer (410) and the support plate (450). The buffer member may cushion the impact transmitted from the window layer (410) to the support plate (450).

[0100] In one embodiment, the window layer (410) may include a glass layer. In some embodiments, the window layer (410) may have a protective film disposed thereon. For example, a protective film may be disposed on the upper portion of the window layer (410) to protect it from external impact. In one embodiment, the window layer (410) may include ultra-thin glass (UTG). In some embodiments, the window layer (410) may include a polymer. In this case, the window layer (410) may include polyethylene terephthalate (PET) or polyimide (PI). In some embodiments, the window layer (410) may be disposed in multiple layers to include a glass layer and a polymer.

[0101] According to one embodiment, the window layer (410), the polarizing layer (420), the display panel (430), the polymer layer (440), and the support plate (450) may be arranged to cross at least a portion of a first surface (e.g., the first surface (211) of FIG. 2A) of the first housing (e.g., the first housing (210) of FIG. 2A) and a third surface (e.g., the third surface (221) of FIG. 2A) of the second housing (e.g., the second housing (220) of FIG. 2A). According to one embodiment, the reinforcing plates (461, 462) may include a first reinforcing plate (461) corresponding to the first housing (e.g., the first housing (210) of FIG. 2A) and a second reinforcing plate (462) corresponding to the second housing (e.g., the second housing (220) of FIG. 2A). According to one embodiment, the reinforcing plates (461, 462) provide rigidity for the display (400) and can be used as a ground to prevent or reduce malfunction of the display (400). According to one embodiment, the reinforcing plates (461, 462) can be formed of a metal material. According to one embodiment, the reinforcing plates (461, 462) can be formed of SUS, CU or AL. According to one embodiment, the window layer (410), the polarizing layer (420), the display panel (430), the polymer layer (440), the support plate (450) and the reinforcing plates (461, 462) can be attached to each other via an adhesive (P1, P2, P3) (or adhesive). For example, the adhesive (P1, P2, P3) can include at least one of an optical clear adhesive (OCA), a pressure sensitive adhesive (PSA), a heat-reactive adhesive, a general adhesive or a double-sided tape.

[0102] According to one embodiment, the display panel (430) may include a plurality of pixels and a wiring structure (e.g., an electrode pattern). According to one embodiment, the polarizing layer (420) may selectively transmit light generated from a light source of the display panel (430) and vibrating in a certain direction. According to one embodiment, the display panel (430) and the polarizing layer (420) may be formed integrally. According to one embodiment, the display (400) may also include a touch panel (not shown).

[0103] In one embodiment, the polymer layer (440) is disposed under the display panel (430), thereby providing a dark background for ensuring visibility of the display panel (430) and may be formed as a buffering material for buffering. In some embodiments, to ensure waterproofing of the display (400), the polymer layer (440) may be removed or disposed under the support plate (450).

[0104] In one embodiment, the support plate (450) can provide a bending characteristic to the display (400). For example, the support plate (450) can be formed of a non-metallic thin-plate material, such as fiber reinforced plastics (FRP) (e.g., carbon fiber reinforced plastics (CFRP) or glass fiber reinforced plastics (GFRP)) having a rigid characteristic for supporting the display panel (430). In one embodiment, the support plate (450) can include a first flat portion (451) corresponding to a first housing (e.g., the first housing (210) of FIG. 2A), a second flat portion (452) corresponding to a second housing (e.g., the second housing (220) of FIG. 2A), and a bending portion (453) (flexible portion or bending portion) connecting the first flat portion (451) and the second flat portion (452). According to one embodiment, the banding portion (453) may include a plurality of openings (4531) spaced apart from each other. According to one embodiment, the bending characteristic of the banding portion (453) may be determined through at least one of the size, shape, or arrangement density of at least some of the openings among the plurality of openings (4531). In some embodiments, the support plate (450) may be formed of a metal material such as SUS (steel use stainless) (e.g., STS (stainless steel)), Cu, Al, or a metal CLAD (e.g., a laminated member in which SUS and Al are alternately arranged). In this case, the support plate (450) may have a plurality of openings formed throughout the entire area so that a detection operation of the digitizer panel (470) arranged below is induced. In one embodiment, the support plate (450) can help reinforce the rigidity of an electronic device (e.g., the electronic device (200) of FIG. 2A), shield ambient noise, and dissipate heat emitted from surrounding heat-emitting components.

[0105] According to one embodiment, the display (400) may be disposed under the support plate (450) and may include a digitizer panel (470) as a detection member that receives an input from an electronic pen (e.g., a stylus). According to one embodiment, the digitizer panel (470) may include coil members disposed on a dielectric substrate (e.g., a dielectric film or a dielectric sheet) so as to detect an electromagnetic induction type resonant frequency applied from the electronic pen. According to one embodiment, the digitizer panel (470) may include a first digitizer panel (471) corresponding to a first housing (e.g., the first housing (210) of FIG. 2A) and a second digitizer panel (472) corresponding to a second housing (e.g., the second housing (220) of FIG. 2A). In one embodiment, the first digitizer panel (471) and the second digitizer panel (472) may be physically and / or electrically connected in the folding area (230C) of the display (400). According to one embodiment, the first digitizer panel (471) and the second digitizer panel (472) may be electrically connected to substrates (e.g., substrates 271 and 272 of FIG. 4) of an electronic device (e.g., electronic device (200) of FIG. 4) through connecting members (not shown), thereby operating as a single digitizer panel. In some embodiments, the first digitizer panel (471) and the second digitizer panel (472) may be operated separately. In some embodiments, the first digitizer panel (471) and the second digitizer panel (472) may be formed integrally and may operate separately.

[0106] According to one embodiment, the display (400) may include at least one functional member (not shown) disposed between the polymer layer (440) and the support plate (450), or under the support plate (450). According to one embodiment, the functional member may include a graphite sheet for heat dissipation, an added display, a force touch FPCB, a fingerprint sensor FPCB, an antenna radiator for communication, or a conductive / non-conductive tape. According to one embodiment, the functional member may be individually disposed in a first housing (e.g., a first housing (210) of FIG. 2A) and a second housing (e.g., a second housing (220) of FIG. 2A) if the functional member is not bendable. In one embodiment, the functional member, if bendable, may be arranged from a first housing (e.g., the first housing (210) of FIG. 2a) to at least a portion of a second housing (e.g., the second housing (220) of FIG. 2a) via a hinge device (e.g., the hinge devices (320, 320-1, 320-2) of FIG. 4).

[0107] According to one embodiment, the display (400) may include a bending portion (432) arranged in a manner of being folded from the display panel (430) to at least a portion of the back surface (e.g., the −z-axis direction of FIG. 4) of the display (400). According to one embodiment, the bending portion (432) may include an extension portion (4321) extending from the display panel (430) and including a control circuit (4321a), and a flexible substrate (4322) electrically connected to the extension portion (4321) and including a plurality of electrical elements. According to one embodiment, the control circuit (4321a) may include a display driver IC (DDI) or a touch display driver IC (TDDI) arranged in the extension portion (4321) having an electrical wiring structure. According to one embodiment, the control circuit (4321a) may have a chip on panel (COP) or chip on plastic (COP) structure arranged directly in the extension portion (4321). In some embodiments, the control circuit (4321a) may have a chip on film (COF) structure disposed on a separate connecting film (not shown) connecting the extension (4321) and the flexible substrate (4322). According to one embodiment, the display (400) may include a plurality of electrical elements (not shown) disposed on the flexible substrate (4322). According to one embodiment, the display (400) may include a connecting member (4323) extending from the flexible substrate (4322) and electrically connected to a substrate (e.g., the second substrate (272) of FIG. 4) of an electronic device (e.g., the electronic device (200) of FIG. 4). According to one embodiment, the plurality of electrical elements may include passive elements such as a touch IC, a flash memory for a display, an ESD prevention diode, a pressure sensor, a fingerprint sensor, or a decap.According to one embodiment, when the banding portion (432) is positioned in an area facing the first housing (e.g., the first housing (210) of FIG. 2A) of the display (400), the connecting member (4323) may be electrically connected to another substrate (e.g., the first substrate (271) of FIG. 4) of the electronic device (e.g., the electronic device (200) of FIG. 4).

[0108] The display (400) described above is merely an example for explaining the present invention, and the display (400) does not necessarily have to include all of the components described above. Therefore, it may be possible to configure the display (400) by omitting some of the components described above or adding some of them.

[0109] According to one embodiment, at least some of the plurality of layers (e.g., window layer (410), polarizing layer (420), display panel (430), polymer layer (440), support plate (450), digitizer panel (470), reinforcing plates (461, 462)) constituting the display (400) may be disposed separately in the first housing (210) and the second housing (220) with respect to the folding axis (A) in the folding area (230C) of the display (400). For example, a layer (e.g., digitizer panel (470), reinforcing plates (461, 462)) formed of a material (e.g., a material including a metal component) that may undergo plastic deformation in the folding area (230C) when folded together with the electronic device (200) may be disposed separately in the first housing (210) and the second housing (220) with respect to the folding axis (A). In one embodiment, referring to FIG. 5, the digitizer panel (470) may be divided into a first digitizer panel (471) disposed in the first housing (210) and a second digitizer panel (472) disposed in the second housing (220). In one embodiment, the reinforcing plates (461, 462) may be divided into a first reinforcing plate (461) disposed in the first housing (210) and a second reinforcing plate (462) disposed in the second housing (220).

[0110] Hereinafter, the layers of the display that are separated and arranged in the first housing (210) and the second housing (220) based on the folding axis (A) will be described as plates (510, 520) (e.g., the first plate (510) of FIG. 8A, the second plate (520) of FIG. 8A). In one embodiment, the plates (510, 520) may face a mechanism located at the bottom of the display (400). For example, the plates (510, 520) may face the first housing (210), the second housing (220), the hinge device (320, 320-1, 320-2), the first hinge plate (311), the second hinge plate (312), and / or the center bar (313).

[0111] In one embodiment, the plates (510, 520) may include a first plate (510) disposed in a first housing (210) and a second plate (520) disposed in a second housing (220). In one embodiment, the first plate (510) may be a first digitizer panel (471) and the second plate (520) may be a second digitizer panel (472). For example, the first plate (510) may include conductive wiring (not shown) and / or via holes (not shown). For example, the second plate (520) may include conductive wiring (not shown) and / or via holes (not shown). In one embodiment, when the digitizer panel (470) is omitted from the display (400) or the reinforcing plate (460) is disposed under the digitizer panel (470), the first plate (510) may be a first reinforcing plate (461) and the second plate (520) may be a second reinforcing plate (462). In one embodiment, the first plate (510) may be a combined structure of the first digitizer panel (471) and the first reinforcing plate (461) disposed in the first housing (210). The second plate (520) may be a combined structure of the second digitizer panel (472) and the second reinforcing plate (462) disposed in the second housing (220). In addition, the first plate (510) and the second plate (520) may be one of the layers of the display that are separated and arranged in the first housing (210) and the second housing (220) based on the folding axis (A).

[0112] In one embodiment, the first plate (510) and the second plate (520) are disposed separately in the first housing (210) and the second housing (220) with respect to the folding axis (A), so that a gap may be formed between the first plate (510) and the second plate (520). As the gap between the first plate (510) and the second plate (520) increases, the area supporting the layers of the display (400) in the folding area (230C) of the display (400) decreases, so that when an external force is applied between the gap between the first plate (510) and the second plate (520), damage may occur to the display (400). In one embodiment, when the gap between the first plate (510) and the second plate (520) is reduced in the folding area (230C), during the folding operation of the electronic device (200), the end portion (511) of the first plate (510) (e.g., the first end portion) and / or the end portion (521) of the second plate (520) (e.g., the second end portion) may come into contact with a mechanism (e.g., the first housing (210), the second housing (220), the hinge device (320, 320-1, 320-2)) located at the bottom of the display (400), causing plastic deformation or damage to the first plate (510) and the second plate (520).

[0113] Meanwhile, when the first plate (510) is the first digitizer panel (471) and the second plate (520) is the second digitizer panel (472), the larger the gap between the first plate (510) and the second plate (520), the lower the recognition rate of the digitizer panel (470) for the electronic pen (e.g., stylus) in the folding area (230C).

[0114] According to one embodiment of the present disclosure, a bending member (600, 700, 800, 900) (e.g., the bending member (600) of FIG. 8A, the bending member (700) of FIG. 12A, the bending member (800) of FIG. 13, and the bending member (900) of FIG. 14) may be disposed between the display (400) and the foldable housing (210, 220). In one embodiment, the bending member (600, 700, 800, 900) may be disposed in a space between the display (400) and the foldable housing (210, 220). In one embodiment, the bending member (600, 700, 800, 900) may be folded together with the electronic device (200) as the electronic device (200) transitions from an unfolded state to a folded state. The end portion (511) of the first plate (510) and the end portion (521) of the second plate (520) can be supported by the banding member (600, 700, 800, 900) and bent toward the folding area (230C) that is deformed into a curved shape. In one embodiment, the end portion (511) of the first plate (510) and the end portion (521) of the second plate (520) can be bent toward the folding area (230C) by directly contacting the banding member (600, 700, 800, 900). In one embodiment, the end portion (511) of the first plate (510) and the end portion (521) of the second plate (520) may be indirectly supported by the bending member (600, 700, 800, 900) through the layer of the display (400) disposed between the bending member (600, 700, 800, 900) and the plates (510, 520). Therefore, even if the gap between the first plate (510) and the second plate (520) is reduced, the end portions of the plates (510, 520) may not come into contact with the mechanism disposed below the display (400) as they bend toward the folding area (230C) during the folding operation of the electronic device (200).Accordingly, the electronic device (200) can enhance the durability of the display (400) in the folding area (230C) by reducing the gap between the plates (510, 520) while maintaining the thickness. In one embodiment, when the plates (510, 520) are digitizer panels (470), the recognition rate of the digitizer panel (470) for an electronic pen (e.g., stylus) in the folding area (230C) can be improved as the gap between the digitizer panels (471, 472) in the folding area (230C) is reduced. For example, when the electronic device (200) is in an unfolded state, the gap between the plates (510, 520) (e.g., digitizer panels (471, 472)) may be smaller than the thickness of the plates (510, 520) (e.g., digitizer panels (471, 472)). A detailed description of the banding members (600, 700, 800, 900) will be provided with reference to FIGS. 6a to 14 below.

[0115] FIG. 6A is an assembly diagram of a display, a bending member, and a foldable housing according to an embodiment of the present disclosure. FIG. 6B is a diagram showing a state in which a bending member is positioned in a foldable housing according to an embodiment of the present disclosure. FIG. 7 is an exploded perspective view of a bending member according to an embodiment of the present disclosure. FIG. 8A is a cross-sectional view taken along line XX of the drawing shown in FIG. 6B, showing a state in which a base layer of the bending member is attached to the foldable housing via a first adhesive member. FIG. 8B is an enlarged view of the bending member of FIG. 8A. FIG. 8C is a cross-sectional view taken along line XX of the drawing shown in FIG. 6B, showing a state in which a base layer of the bending member is attached to plates via a first adhesive member. FIGS. 9A and 9B are drawings of the electronic device of FIG. 8A in a folded state, with the ends of the first plate and the ends of the second plate bent along the folding area of ​​the display through the bending member.

[0116] According to one embodiment, a bending member (600, 700, 800, 900) (e.g., the bending member (600) of FIG. 8A, the bending member (700) of FIG. 12A, the bending member (800) of FIG. 13, the bending member (900) of FIG. 14) may be disposed between a display (400) (e.g., the first display (230) of FIG. 2A, the display 400 of FIG. 5)) and a foldable housing (210, 220), as illustrated in FIGS. 6A and 6B. For example, the bending member (600) may be disposed between the plates (510, 520) of the display (400) and the foldable housing (210, 220). In one embodiment, the banding member (600) may be positioned within the folding area (230C) to face the plates (510, 520). In one embodiment, the banding member (600) may bend the ends of the plates (510, 520) based on the folding or folding action of the electronic device (200).

[0117] According to one embodiment, as illustrated in FIG. 8A, which will be described later, the display (400) (e.g., the first display (230) of FIGS. 2A and 4) may be fixed to the foldable housing (210, 220) via a first side adhesive member (530) disposed between the first housing (210) and the display (400) and a second side adhesive member (540) disposed between the second housing (220) and the display (400). In one embodiment, the first side adhesive member (530) may be disposed between the first housing (210) and the first plate (510) to adhere the first housing (210) and the first plate (510). In one embodiment, the second side adhesive member (540) may be disposed between the second housing (220) and the second plate (520) to adhere the second housing (220) and the second plate (520). In one embodiment, the banding member (600) can be positioned between the first side adhesive member (530) and the second side adhesive member (540) to support the plates (510, 520).

[0118] In one embodiment, referring to FIGS. 8A and 8C described below, the banding member (600) can support the first plate (510) and the second plate (520). In one embodiment, the banding member (600) can come into contact with the first plate (510) and the second plate (520) when the electronic device (200) (e.g., the electronic device (101) of FIG. 1) is in an unfolded state. In one embodiment, the banding member (600) can support the end portion (511) of the first plate (510) and the end portion (521) of the second plate (520) when the electronic device (200) is switched from an unfolded state to a folded state. In one embodiment, referring to FIGS. 9A and 9B described below, when the electronic device (200) is in a folded state, the end portion (511) of the first plate (510) and the end portion (521) of the second plate (520) may be in direct contact with the bending member (600) and may be bent toward the folding area (230C). In one embodiment, the end portion (511) of the first plate (510) and the end portion (521) of the second plate (520) may be indirectly supported by the bending member (600) through a layer (e.g., a sponge layer, a polymer layer, a graphite layer, a metal layer, an adhesive layer, etc.) of the display (400) disposed between the bending member (600) and the plates (510, 520). In one embodiment, the banding member (600) can press the end portion (511) of the first plate (510) and the end portion (521) of the second plate (520) toward the folding area (230C) that has been deformed into a shape having a curved surface. Accordingly, the end portion (511) of the first plate (510) and the end portion (521) of the second plate (520) can bend toward the folding area (230C) when the electronic device (200) is switched from an unfolded state to a folded state.

[0119] In one embodiment, referring to FIGS. 6A and 6B, the bending member (600) may face a mechanism that is at least partially disposed at the bottom (e.g., in the -Z direction with respect to FIG. 6A) of the display (400). For example, the bending member (600) may face a hinge module that rotatably connects the first housing (210) and the second housing (220). In one embodiment, the hinge module may include a first hinge plate (311), a second hinge plate (312), a center bar (313), a first hinge device (320), a second hinge device (320-1), and a connection module (320-2). In one embodiment, referring to FIG. 8A, which will be described later, the bending member (600) may be disposed on the foldable housing (210, 220) to cover the hinge module.

[0120] According to one embodiment, as illustrated in FIG. 7, the banding member (600) may include a base layer (610), a protective layer (620, 630) positioned on the top (e.g., in the +Z direction with respect to FIG. 7) and / or the bottom (e.g., in the -Z direction with respect to FIG. 7) of the base layer (610). In one embodiment, the protective layer (620, 630) may include a first cover layer (620) positioned on the top of the base layer (610) and / or a second cover layer (630) positioned on the bottom of the base layer (610). In one embodiment, the banding member (600) may include only one of the first cover layer (620) and the second cover layer (630), and the other may be omitted. In the following descriptions of FIGS. 6A to 10B, the banding member (600) is described as including a base layer (610), a first cover layer (620), and a second cover layer (630). However, the present invention may not be limited thereto. In one embodiment, the banding member (600) may be composed of only the base layer (610), and in one embodiment, the banding member (600) may omit at least one of the first cover layer (620) and the second cover layer (630).

[0121] According to one embodiment, as illustrated in FIGS. 7, 8A, and 8B, the base layer (610) may be configured to substantially bend the end portion (511) of the first plate (510) and the end portion (521) of the second plate (520) when the electronic device (200) is converted from an unfolded state to a folded state. In one embodiment, the base layer (610) may be formed of a material having a higher strength than the first cover layer (620) and the second cover layer (630) so that the end portions of the plates (510, 520) can be pressed when the electronic device (200) is converted from an unfolded state to a folded state. For example, the base layer (610) may be formed of a metal material such as aluminum, stainless steel (e.g., SUS, steel use stainless), iron, magnesium, or titanium.

[0122] In one embodiment, the base layer (610) may be formed with a thickness within a range of about 50 μm to 500 μm (e.g., the length in the Z-axis direction of FIG. 8a).

[0123] According to one embodiment, as illustrated in FIGS. 7, 8a, and 8b, the first cover layer (620) may be disposed on top of the base layer (610) to prevent interference between the back surface of the display (400) located on top of the base layer (610) and the base layer (610). For example, the first cover layer (620) may be disposed on top of the base layer (610) to prevent interference between the base layer (610) and the plates (510, 520) of the display (400) and / or the back surface unevenness of the display (400) and the base layer (610). Accordingly, noise generation due to contact between the base layer (610) and the plates (510, 520) of the display (400) and / or the back surface unevenness of the display (400) may be prevented or reduced.

[0124] According to one embodiment, as illustrated in FIGS. 7, 8a, and 8b, the second cover layer (630) may be disposed at the bottom of the base layer (610) to prevent or reduce interference between a mechanism positioned at the bottom of the base layer (610) and the base layer (610). For example, the second cover layer (630) may be disposed at the bottom of the base layer (610) to prevent or reduce interference between the base layer (610) and the foldable housing (210, 220) and / or the hinge module (e.g., the hinge device (320, 320-1, 320-2) of FIG. 4). Accordingly, noise generation due to contact between the base layer (610) and the foldable housing (210, 220) and / or the hinge module may be prevented or reduced.

[0125] According to one embodiment, as illustrated in FIGS. 7, 8a, and 8b, the base layer (610) may include a deformable portion (613), a first fixing portion (611) disposed on one side of the deformable portion (613), and a second fixing portion (612) disposed on the other side of the deformable portion (613). In one embodiment, the deformable portion (613) may be deformed in response to a folding operation of the electronic device (200). For example, the deformable portion (613) may be bent in response to the folding operation of the electronic device (200). In one embodiment, the first fixing portion (611) and the second fixing portion (612) may be relatively undeformed or may be deformed to a small degree when the deformable portion (613) is deformed in response to the folding operation of the electronic device (200). In one embodiment, the fixed portion (611, 612) may not be physically distinct from the deformable portion (613), and may be a portion located at one end and the other end of the deformable portion (613), and may be an area of ​​the base layer (610) in which a lattice structure, a plurality of openings, and / or a plurality of recesses are not formed.

[0126] In one embodiment, the deformation portion (613) may be formed of various structures or materials so as to be able to expand in accordance with the rotational motion of the first housing (210) and the second housing (220). In one embodiment, the deformation portion (613) may include a lattice structure, a plurality of openings and / or a plurality of recesses. In one embodiment, the number of the plurality of openings and / or the plurality of recesses formed in the deformation portion (613) may increase per unit area as they get closer to the folding axis (A). In one embodiment, the depth of the plurality of recesses formed in the deformation portion (613) in the z-axis direction of FIG. 8A may increase as they get closer to the folding axis (A). In one embodiment, the deformation portion (613) may not have separate openings and recesses formed therein, and may be formed of a material that can expand in accordance with the rotational motion of the first housing (210) and the second housing (220). For example, the deformation portion (613) may be formed of a material that is relatively softer than the first fixing portion (611) and the second fixing portion (612) and may be deformed in response to the folding operation of the electronic device (200). Accordingly, the deformation portion (613) may be formed of a lattice structure, a plurality of openings, a plurality of recesses, and / or a soft material and may be expanded in response to the transition of the electronic device (200) from an unfolded state to a folded state, or may be contracted in response to the transition of the electronic device (200) from a folded state to an unfolded state.

[0127] According to one embodiment, a first adhesive member (640) may be disposed on the first fixing member (611) and the second fixing member (612) to adhere the base layer (610) to the foldable housing (210, 220) (e.g., the first housing (210), the second housing (220)) or the display (400) (e.g., the plates (510, 520)). In one embodiment, the first adhesive member (640) may be disposed between the base layer (610) and the foldable housing (210, 220), the base layer (610) and the display (400), or between the base layer (610) and the foldable housing (210, 220) and the base layer (610) and the display (400), respectively.

[0128] In one embodiment, referring to FIGS. 8A and 8B, the first adhesive member (640) may be disposed on at least one of the first fixing portion (611) of the base layer (610) and / or the second fixing portion (612) of the base layer (610) to adhere the base layer (610) to the foldable housing (210, 220).

[0129] In one embodiment, referring to FIGS. 8A and 8B, the first fixing member (611) may be fixed to the first housing (210) via the first-first adhesive member (641). The second fixing member (612) may be fixed to the second housing (220) via the first-second adhesive member (642). Since the first adhesive member (640) is disposed at the lower end of the base layer (610) (e.g., in the -Z direction with reference to FIG. 8A), the length of the first cover layer (620) (e.g., in the X-axis direction with reference to FIG. 8A) may be longer than the length of the second cover layer (630) (e.g., in the X-axis direction with reference to FIG. 8A).

[0130] In one embodiment, referring to FIG. 8C, the first adhesive member (640) may be disposed on at least one of the first fixing member (611) and the second fixing member (612) of the base layer (610) to adhere the base layer (610) to the display (400). In one embodiment, the first fixing member (611) may be fixed to the first plate (510) of the display (400) via the first-first adhesive member (641). The second fixing member (612) may be fixed to the second plate (520) of the display (400) via the first-second adhesive member (642). As the first adhesive member (640) is placed on the top of the base layer (610) (e.g., in the +Z direction based on FIG. 8c), the length of the first cover layer (620) (e.g., in the X-axis direction based on FIG. 8c) may be shorter than the length of the second cover layer (630) (e.g., in the X-axis direction based on FIG. 8c).

[0131] According to one embodiment of the present disclosure, as illustrated in FIGS. 8A and 8C, the base layer (610) may be fixed to the foldable housing (210, 220) or the plates (510, 520) with the first fixing portion (611) and the second fixing portion (612) centered around the deformable portion (613). In this case, when the electronic device (200) is folded, the base layer (610) may be uniformly and symmetrically extended or contracted around the folding axis (A). For example, the base layer (610) may be extended or contracted through the deformable portion (613) in response to the folding operation of the electronic device (200). In one embodiment, the contraction of the base layer (610) may mean that the deformable portion (613) is extended when the electronic device (200) is in a folded state, and that the deformable portion (613) is restored to its original state as the electronic device (200) transitions from a folded state to an unfolded state. In one embodiment, as the base layer (610) is uniformly extended or contracted in a symmetrical shape, the end portion (511) of the first plate (510) and the end portion (521) of the second plate (520) can be bent symmetrically with respect to the folding axis (A).

[0132] According to one embodiment, as illustrated in FIGS. 7 to 9B, the first cover layer (620) and the second cover layer (630) may be formed to a size that includes the deformable portion (613) of the base layer (610). For example, referring to FIG. 8A, the first cover layer (620) and the second cover layer (630) may be formed to a size that can cover the deformable portion (613) of the base layer when the electronic device (200) is in an unfolded state. In one embodiment, referring to FIGS. 7 and 8A, the first cover layer (620) may be formed to a size that substantially includes the base layer (610). The second cover layer (630) may be formed to a size that is included in the base layer (610).

[0133] In one embodiment, when the plurality of openings and / or the plurality of recesses formed in the deformation portion (613) come into contact with another structure, noise may be generated. For example, the other structure may be a protrusion of the display (400), a foldable housing (210, 220), a hinge device (320, 320-1, 320-2), a first hinge plate (311), or a second hinge plate (312). When the plurality of openings and / or the plurality of recesses of the deformation portion (613) come into contact with another structure, a scratching sound or a cracking sound may be generated, which may degrade the usability of the electronic device (200), and the operating feel of the electronic device (200) may be degraded due to friction between the other structure and the deformation portion (613) during a folding operation. The first cover layer (620) and the second cover layer (630) of the present disclosure may be formed of a non-adhesive and soft material such as a rubber, urethane, or polyurethane (PU) series material (e.g., thermoplastic polyurethane (TPU)). The first cover layer (620) and the second cover layer (630) may cover the deformable portion (613) when the electronic device (200) is in a folded and / or unfolded state, thereby preventing or reducing contact (e.g., interference, catching) between other structures (e.g., foldable housings (210, 220), the rear surface of the display (400), and hinge devices (320, 320-1, 320-2)) and the deformable portion (613). Accordingly, when the electronic device (200) is folded, noise and reduced operational feel of the electronic device (200) due to contact between the other structure and the deformation part (613) can be improved or prevented.

[0134] In one embodiment, at least one of the thickness of the first cover layer (620) (e.g., the length in the Z-axis direction of FIG. 8a) and the thickness of the second cover layer (e.g., the length in the Z-axis direction of FIG. 8a) may be formed to a thickness within a range of about 1 μm to 300 μm.

[0135] In one embodiment, at least one of the first cover layer (620) and the second cover layer (630) may be formed to be sized to cover the deformable portion (613) of the base layer (610) when the deformable portion (613) is maximally stretched as the electronic device (200) transitions from an unfolded state to a folded state. In one embodiment, referring to FIGS. 9A and 9B , the first cover layer (620) may cover the deformable portion (613) of the base layer (610) when the deformable portion (613) is maximally stretched as the electronic device (200) transitions from a folded state. Accordingly, when the electronic device (200) is in a folded state and the deformation portion (613) is in a maximally extended state, the base layer (610) is covered by the first cover layer (620), thereby preventing contact between the deformation portion (613) and the plates (510, 520) of the display (400) and / or the back surface unevenness of the display (400), thereby preventing or reducing noise generation. In one embodiment, when the base layer (610) is in a folded state and the deformation portion (613) is in a maximally extended state, the base layer (610) is at least partially covered by the second cover layer (630), thereby preventing contact between the deformation portion (613) and a mechanism (e.g., a hinge module), thereby preventing or reducing noise generation.

[0136] According to one embodiment, as illustrated in FIGS. 8A and 8C, when the electronic device (200) is in an unfolded state, the length of the bending portion (453) of the support plate (450) (e.g., the length in the X-axis direction based on FIG. 8A) and the length of the deformation portion (613) of the base layer (610) (e.g., the length in the X-axis direction based on FIG. 8A) may be different from each other. For example, the length of the bending portion (453) of the support plate (450) may be shorter than the length of the deformation portion (613) of the base layer (610). In other words, the length of the deformation portion (613) of the base layer (610) may be longer than the length of the bending portion (453) of the support plate (450).

[0137] In one embodiment, the plurality of openings or the plurality of recesses formed in the deformation portion (613) may be formed at a wider interval than the plurality of openings (4531) formed in the banding portion (453). Accordingly, the elongation of the deformation portion (613) of the base layer (610) may be greater than the elongation of the banding portion (453) of the support plate (450).

[0138] According to one embodiment, as illustrated in FIGS. 8A to 9B, the first cover layer (620) may be fixed to the base layer (610) via the second adhesive member (650). In one embodiment, the first cover layer (620) may be fixed to either the first fixing portion (611) or the second fixing portion (612) of the base layer (610) via the second adhesive member (650). For example, referring to FIGS. 8A, 9A, and 9B, the first cover layer (620) may be fixed to the second fixing portion (612) via the second adhesive member (650). In one embodiment, the first cover layer (620) may be fixed to the first fixing portion (611) via the second adhesive member (650). In summary, the first cover layer (620) may be fixed to the base layer (610) at only one of its two ends.

[0139] In one embodiment, the first cover layer (620) may be secured to the back surface of the display (400) via the second adhesive member (650). For example, the first cover layer (620) may be secured to either the first plate (510) (e.g., the first digitizer panel (471) or the first reinforcing plate (461)) or the second plate (520) (e.g., the second digitizer panel (472) or the second reinforcing plate (462)) of the display (400) via the second adhesive member (650). In summary, the first cover layer (620) may be secured to the back surface of the display (400) at only one of its two ends.

[0140] For example, if both ends of the first cover layer (620) are respectively fixed to the first fixing portion (611) and the second fixing portion (612) via the second adhesive member (650), the first cover layer (620) may be damaged due to friction with the back surface irregularities or plates (510, 520) of the display (400) as the folding operation of the electronic device (200) is repeated. Since the first cover layer (620) of the present disclosure is fixed at only one end to either the first fixing portion (611) or the second fixing portion (612) via the second adhesive member (650), friction with the back surface irregularities or plates (510, 520) of the display (400) may be reduced even if the folding operation of the electronic device (200) is repeated. In one embodiment, referring to FIG. 9A, the first cover layer (620) may have one end fixed to the second fixing portion (612) and the other end not fixed to the first fixing portion (611), and thus the other end may slip (e.g., the 'first movement' direction of FIG. 9A) relative to the first fixing portion (611) in the -Z direction of FIG. 9A based on the transition of the electronic device (200) from the unfolded state to the folded state. In one embodiment, referring to FIG. 9B, the first cover layer (620) may have one end fixed to the second fixing portion (612) and the other end not fixed to the first fixing portion (611), and thus the other end may slip (e.g., the 'first movement' direction of FIG. 9B) relative to the first fixing portion (611) based on the transition of the electronic device (200) from the unfolded state to the folded state. Accordingly, the first cover layer (620) can reduce friction with the counterpart mechanism, such as the first fixing member (611), the back surface protrusions of the display (400), or the plates (510, 520), as the electronic device (200) slips in response to the folding or unfolding motion, thereby reducing the frequency of damage. The above description can also be applied to a case where the other end of the first cover layer (620) is fixed to the first fixing member (611) and one end is not fixed to the second fixing member (612).

[0141] According to one embodiment, as illustrated in FIGS. 8A to 9B, the second cover layer (630) may be fixed to the base layer (610) via a third adhesive member (660). In one embodiment, the second cover layer (630) may be fixed to either the first fixing portion (611) or the second fixing portion (612) of the base layer (610) via the third adhesive member (660). For example, referring to FIGS. 8A, 9B, and 9, the second cover layer (630) may be fixed to the second fixing portion (612) via the third adhesive member (660). In one embodiment, the second cover layer (630) may be fixed to the first fixing portion (611) via the third adhesive member (660). In summary, the second cover layer (630) may be fixed to the base layer (610) at only one of its two ends.

[0142] In one embodiment, the second cover layer (630) can be secured to the foldable housing (210, 220) via the third adhesive member (660). For example, the second cover layer (630) can be secured to either the first housing (210) or the second housing (220) via the third adhesive member (660). In summary, the second cover layer (630) can be secured to the foldable housing (210, 220) at only one of its two ends.

[0143] In one embodiment, the second cover layer (630) can be relatively flexibly bent in response to the folding or unfolding motion of the electronic device (200) compared to a case where both ends of the second cover layer (630) are respectively fixed to the first fixing portion (611) and the second fixing portion (612) via the third adhesive member (660). For example, when both ends of the second cover layer (630) are respectively fixed to the first fixing portion (611) and the second fixing portion (612) via the third adhesive member (660), the second cover layer (630) may be damaged due to friction with structures disposed at the bottom of the display (400) (e.g., the foldable housing (210, 220), the first hinge plate (311), the second hinge plate (312), the hinge devices (320, 320-1, 320-2)) as the folding motion of the electronic device (200) is repeatedly performed. The second cover layer (630) of the present disclosure can reduce friction with a structure disposed at the bottom of the display (400) even when the folding operation of the electronic device (200) is repeatedly performed since only one end thereof is fixed to either the first fixing portion (611) or the second fixing portion (612) via the third adhesive member (660). In one embodiment, referring to FIG. 9A, since one end of the second cover layer (630) is fixed to the second fixing portion (612) and the other end thereof is not fixed to the first fixing portion (611), the other end thereof can slip (e.g., in the 'second movement' direction of FIG. 9A) relative to the first fixing portion (611) based on the electronic device (200) transitioning from an unfolded state to a folded state. In one embodiment, referring to FIG. 9b, the second cover layer (630) may have one end fixed to the second fixing portion (612) and the other end not fixed to the first fixing portion (611), so that the other end may slip relative to the first fixing portion (611) in the second movement direction of FIG. 9b as the electronic device (200) transitions from an unfolded state to a folded state.Accordingly, the second cover layer (630) can reduce friction with the counterpart mechanism, such as the foldable housing (210, 220), the hinge device (320, 320-1, 320-2), the first hinge plate (311), and the second hinge plate (312), as the electronic device (200) slips in response to the folding or unfolding motion, thereby reducing the frequency of damage. The above description can also be applied to a case where the other end of the second cover layer (630) is fixed to the first fixing part (611) and one end is not fixed to the second fixing part (612).

[0144] According to one embodiment, as illustrated in FIGS. 8A and 8B, when the second adhesive member (650) is disposed between the second fixing member (612) and the first cover layer (620), when viewed in a direction perpendicular to the display (400) (e.g., the z-axis direction), the second adhesive member (650) may at least partially overlap the first adhesive member (640) (e.g., the first-second adhesive member (642)) disposed between the second fixing member (612) and the second housing (220).

[0145] According to one embodiment, as illustrated in FIG. 8c, when the third adhesive member (660) is disposed between the second fixing member (612) and the second cover layer (630), when viewed in a direction perpendicular to the display (400) (e.g., the z-axis direction), it may at least partially overlap the first adhesive member (640) (e.g., the first-second adhesive member (642)) disposed between the second fixing member (612) and the second plate (520).

[0146] In one embodiment, the thickness (e.g., length in the Z-axis direction based on FIG. 8A) of the second adhesive member (650) and the third adhesive member (660) may be formed to a thickness within a range of about 1 μm to 200 μm.

[0147] According to one embodiment, the first side adhesive member (530), the second side adhesive member (540), the first adhesive member, the second adhesive member (650), and / or the third adhesive member (660) may include at least one of a double-sided tape, a waterproof tape, an optical clear adhesive (OCA), a pressure sensitive adhesive (PSA), a heat-reactive adhesive, or a general adhesive.

[0148] In one embodiment, the thickness of the first side adhesive member (530) (e.g., the length in the Z-axis direction of FIG. 8A) and the thickness of the second side adhesive member (540) (e.g., the length in the Z-axis direction of FIG. 8A) may be thicker than the thickness of the first cover layer (620) and the thickness of the second cover layer (630). In one embodiment, the thickness of the first side adhesive member (530) and the thickness of the second side adhesive member (540) may be thicker than at least one of the thickness between the base layer and the first cover layer (620) and the thickness between the base layer (610) and the second cover layer (630).

[0149] According to one embodiment, as illustrated in FIG. 9B, the bending member (600) may be supported at least in part by the center bar (313) when the electronic device (200) is in a folded state. For example, the bending member (600) may be supported in a region corresponding to the folding region (230C) by the center bar (313). In one embodiment, the second cover layer (630) of the bending member (600) may be in contact with the center bar (313), but is not limited thereto.

[0150] In one embodiment, referring to FIG. 9B, the banding member (600) may be supported by the first hinge plate (311) and the second hinge plate (312) when the electronic device (200) is in a folded state. In one embodiment, the second cover layer (630) of the banding member (600) may be in contact with the first hinge plate (311) and the second hinge plate (312), but is not limited thereto.

[0151] FIG. 10A is a drawing of an embodiment in which deformation portions are formed in the first and second directions, respectively, based on the central region of the base layer of FIG. 8A. FIG. 10B is a drawing of a state in which the end of the first plate and the end of the second plate are bent along the folding region of the display by a bending member when the electronic device of FIG. 10A is in a folded state.

[0152] In the following description, the deformation portion (613) of the banding member (600) described through FIGS. 6A to 9B may be an embodiment in which the center (614) is located in a first direction (e.g., + X direction based on FIG. 10A) and a second direction (e.g., - X direction based on FIG. 10B). Descriptions of configurations identical or similar to those described through FIGS. 6A to 9B will be omitted.

[0153] According to one embodiment, as illustrated in FIGS. 10A and 10B, the base layer (610) of the banding member (600) may include a first deformable portion (613-1) (e.g., the deformable portion (613) of FIG. 8A) located in a first direction (e.g., the + X direction with respect to FIG. 10A) with respect to the center (614) and a second deformable portion (613-2) (e.g., the deformable portion (613) of FIG. 8A) located in a second direction (e.g., the - X direction with respect to FIG. 10A) with respect to the center (614). In one embodiment, the center (614) may be an area corresponding to the folding area (230C).

[0154] In one embodiment, referring to FIG. 10B, the base layer (610) may be bent about a center portion (614) corresponding to the folding axis (A) as the electronic device (200) transitions from an unfolded state to a folded state. Based on the transition of the electronic device (200) from an unfolded state to a folded state, the first deformable portion (613-1) and the second deformable portion (613-2) may be stretched.

[0155] In one embodiment, referring to FIG. 10b, the central portion (614) may be bent as the electronic device (200) transitions from an unfolded state to a folded state.

[0156] In one embodiment, the first deformation portion (613-1) and the second deformation portion (613-2) may be formed of various structures or various materials so as to be expandable according to the rotational motion of the first housing (210) and the second housing (220). In one embodiment, the first deformation portion (613-1) and the second deformation portion (613-2) may include a lattice structure, a plurality of openings and / or a plurality of recesses. In one embodiment, the number of the plurality of openings and / or the plurality of recesses formed in the first deformation portion (613-1) and the second deformation portion (613-2) may increase per unit area as they get closer to the folding axis (A). In one embodiment, the depth of the plurality of recesses formed in the first deformation portion (613-1) and the second deformation portion (613-2) in the z-axis direction of FIG. 10A may increase as they get closer to the folding axis (A). Accordingly, the first deformation portion (613-1) and the second deformation portion (613-2) are formed of a lattice structure, a plurality of openings, a plurality of recesses, and / or a soft material so that the electronic device (200) can expand in response to a transition from an unfolded state to a folded state, or contract in response to a transition from a folded state to an unfolded state.

[0157] According to one embodiment, as illustrated in FIG. 10B, at least a portion of the bending member (600) may be supported by the center bar (313) when the electronic device (200) is in a folded state. For example, the bending member (600) may be supported by the center bar (313) in an area (e.g., a center area (614)) corresponding to the folding area (230C). In one embodiment, the second cover layer (630) of the bending member (600) may be in contact with the center bar (313), but is not limited thereto. In one embodiment, the second cover layer (630) may be in contact with the center bar (313) in an area corresponding to the center area (614) of the base layer (610).

[0158] In one embodiment, referring to FIG. 10b, the banding member (600) may be supported by the first hinge plate (311) and the second hinge plate (312) when the electronic device (200) is in a folded state. In one embodiment, the second cover layer (630) of the banding member (600) may be in contact with the first hinge plate (311) and the second hinge plate (312), but is not limited thereto.

[0159] FIG. 11 is a drawing of a state in which a bending member is positioned in a foldable housing according to one embodiment of the present disclosure. FIG. 12a is a cross-sectional view taken along the YY line illustrated in FIG. 11. FIG. 12b and FIG. 12c are drawings of a state in which the end of the first plate and the end of the second plate are bent along the folding area of ​​the display by the bending member when the electronic device of FIG. 12a is in a folded state.

[0160] The following description may be a description of a banding member (700) of one embodiment of the banding member (600) described through FIGS. 6a to 9b. Descriptions of configurations identical or similar to the above-described configurations will be omitted.

[0161] According to one embodiment, as illustrated in FIGS. 11 and 12A, the banding member (700) may include a base layer (710), a first cover layer (720) positioned at an upper end of the base layer (710) (e.g., in the +Z direction with respect to FIG. 12A), and a second cover layer (730) positioned at a lower end of the base layer (710). In one embodiment, the banding member (700) may include only one of the first cover layer (720) and the second cover layer (730), and the other may be omitted. In the following description, the banding member (700) will be described on the assumption that it includes the base layer (710), the first cover layer (720), and the second cover layer (730).

[0162] According to one embodiment, as illustrated in FIGS. 12A and 12B , the base layer (710) may be formed of a soft material and may deform in response to a folding operation of the electronic device (200) (e.g., the electronic device (101) of FIG. 1 ). Accordingly, the base layer (710) may expand in response to a transition of the electronic device (200) from an unfolded state to a folded state, or may contract in response to a transition of the electronic device (200) from a folded state to an unfolded state.

[0163] According to one embodiment, as illustrated in FIGS. 12A and 12B , the first cover layer (720) may be adhered to the upper end of the base layer (710) to prevent interference between the back surface of the display (400) (e.g., the first display (230) of FIGS. 2A and 4 ) positioned on the upper end of the base layer (710) and the base layer (710). For example, the first cover layer (720) may be adhered to the upper end of the base layer (710) to prevent interference between the base layer (710) and the plates (510, 520) of the display (400) and / or the back surface unevenness of the display (400) and the base layer (710). Accordingly, noise generation due to contact between the base layer (710) and the plates (510, 520) of the display (400) and / or the back surface unevenness of the display (400) may be prevented or reduced.

[0164] According to one embodiment, as illustrated in FIGS. 12A and 12B, the second cover layer (730) may be adhered to the lower end of the base layer (710) to prevent interference between the base layer (710) and a mechanism positioned at the lower end of the base layer (710). For example, the second cover layer (730) may be adhered to the lower end of the base layer (710) to prevent interference between the base layer (710) and the foldable housing (210, 220) and / or the hinge module (e.g., the first hinge plate (311), the second hinge plate (312), the center bar (313), the first hinge device (320), the second hinge device (320-1), the connection module (320-2)). Accordingly, noise generation due to contact between the base layer (710) and the foldable housing (210, 220) and / or the hinge module may be prevented or reduced.

[0165] According to one embodiment, the base layer (710), the first cover layer (720) and the second cover layer (730) may be formed of a non-adhesive and / or soft material such as a rubber, urethane, or polyurethane (PU) series material (e.g., one is thermoplastic polyurethane (TPU)).

[0166] According to one embodiment, a first adhesive member (740) may be disposed between the base layer (710) and the foldable housings (210, 220), as illustrated in FIGS. 12A and 12B. In one embodiment, the first adhesive member (740) may adhere one end of the first housing (210) and the base layer (710). In one embodiment, referring to FIG. 12A, the first adhesive member (740) may adhere the other end of the second housing (220) and the base layer (710). In this case, since the first adhesive member (740) is disposed at the lower end of the base layer (710) (e.g., in the -Z direction with reference to FIG. 12A), the length of the first cover layer (720) (e.g., in the X-axis direction with reference to FIG. 12A) may be longer than the length of the second cover layer (730) (e.g., in the X-axis direction with reference to FIG. 12A).

[0167] According to one embodiment, a first adhesive member (740) may be disposed between the base layer (710) and the display (400). In one embodiment, the first adhesive member (740) may bond one end of the base layer (710) to a first plate (510) (e.g., a first digitizer panel (471) or a first reinforcing plate (461)). In one embodiment, the first adhesive member (740) may bond the other end of the base layer (710) to a second plate (520) (e.g., a second digitizer panel (472) or a second reinforcing plate (462)). In this case, since the first adhesive member (740) is placed on the top of the base layer (710) (e.g., in the +Z direction based on FIG. 12a), the length of the first cover layer (720) (e.g., in the X-axis direction based on FIG. 12a) may be shorter than the length of the second cover layer (730) (e.g., in the X-axis direction based on FIG. 12a).

[0168] According to one embodiment of the present disclosure, as illustrated in FIG. 12B, the bending member (700) may be folded together with the electronic device (200) as the electronic device (200) transitions from an unfolded state to a folded state. The end portion (511) of the first plate (510) and the end portion (521) of the second plate (520) may be supported by the bending member (700) and bent toward the folding area (230C) that is deformed into a curved shape. For example, the end portion (511) of the first plate (510) and the end portion (521) of the second plate (520) may be in direct contact with the bending member (700) and bent toward the folding area (230C). Accordingly, the electronic device (200) can reduce the gap between the plates (510, 520) while maintaining the thickness, thereby enhancing the durability of the display (400) in the folding area (230C). In one embodiment, when the plates (510, 520) are digitizer panels (470), the recognition rate of the digitizer panel (470) for an electronic pen (e.g., a stylus) in the folding area (230C) can be improved as the gap between the digitizer panels (470) in the folding area (230C) is reduced.

[0169] In one embodiment, referring to FIGS. 12B and 12C, the banding member (700) may have one end fixed to the second housing (220) by bonding the base layer (710) and the second housing (220) via the first adhesive member (740), and the other end may not be fixed to the first housing (210). In this case, the other end of the banding member (700) may slip in the first movement direction of FIG. 12C with respect to the first plate (510) based on the transition of the electronic device (200) from the unfolded state to the folded state. Accordingly, as the banding member (700) slips in response to the folding or unfolding motion of the electronic device (200), friction with the opposing mechanism may be reduced, thereby reducing the frequency of damage occurrence. The above description can be equally applied to a case where the other end of the banding member (700) is fixed to the first housing (210) by bonding the base layer (710) and the first housing (210) via the first adhesive member (740) and one end is not fixed to the second housing (220).

[0170] In one embodiment, referring to FIG. 12C, the bending member (700) can be spaced apart from the hinge module. In one embodiment, referring to FIG. 12C, the bending member (700) can be spaced apart from the center bar (313) at least partially when the electronic device (200) is in an unfolded state and a folded state. For example, the bending members (600, 700) can have an area corresponding to the folding area (230C) spaced apart from the center bar (313). The second cover layer (730) of the bending member (700) is adhered to the lower surface (e.g., the surface facing the -Z direction with reference to FIG. 12A) of the base layer (710), so that slipping may not occur with respect to the base layer (710) when the electronic device (200) is switched from an unfolded state to a folded state. The second cover layer (730) may not be damaged by contact with the center bar (313) and the hinge device (320-2) as the banding member (700) is spaced apart in the +Z direction with respect to FIG. 12b when the electronic device (200) is in a folded state.

[0171] FIG. 13 is a drawing of various types of banding members arranged between a display and a foldable housing according to one embodiment of the present disclosure.

[0172] The following description may be a description of a banding member (800) of one embodiment of the banding member (600, 700) described through FIGS. 6a to 12b. Descriptions of configurations identical or similar to the above-described configurations will be omitted.

[0173] According to one embodiment, the banding member (800) illustrated in FIG. 13 may be an embodiment in which the second adhesive member (650) and the third adhesive member (660) are omitted from the banding member (600) illustrated in FIG. 8A. For example, the banding member (800) of FIG. 13 may have a configuration substantially identical to the banding member (600) of FIG. 8A except for the second adhesive member (650) and the third adhesive member (660).

[0174] According to one embodiment, as illustrated in FIG. 13, the banding member (800) may include a base layer (810), a first cover layer (820) positioned at the top of the base layer (810) (e.g., in the +Z direction based on FIG. 13), and a second cover layer (830) positioned at the bottom of the base layer (810) (e.g., in the -Z direction based on FIG. 13). In one embodiment, the banding member (800) may include only one of the first cover layer (820) and the second cover layer (830), and the other may be omitted. In the following description, the banding member (800) will be described on the assumption that it includes the base layer (810), the first cover layer (820), and the second cover layer (830).

[0175] According to one embodiment, as illustrated in FIG. 13, the first cover layer (820) may be adhered to the upper end of the base layer (810) to prevent interference between the back surface of the display (400) (e.g., the first display (230) of FIGS. 2A and 4) positioned on the upper end of the base layer (810) and the base layer (810). For example, the first cover layer (820) may be adhered to the upper end of the base layer (810) to prevent interference between the base layer (810) and the plates (510, 520) of the display (400) and / or the back surface unevenness of the display (400) and the base layer (810). Accordingly, noise generation due to contact between the base layer (810) and the plates (510, 520) of the display (400) and / or the back surface unevenness of the display (400) may be prevented or reduced.

[0176] According to one embodiment, as illustrated in FIG. 13, the second cover layer (830) may be adhered to the lower end of the base layer (810) to prevent interference between a mechanism located at the lower end of the base layer (810) and the base layer (810). For example, the second cover layer (830) may be adhered to the lower end of the base layer (810) to prevent interference between the base layer (810) and the foldable housing (210, 220) and / or the hinge module (e.g., the first hinge plate (311), the second hinge plate (312), the center bar (313), the first hinge device (320), the second hinge device (320-1), and the connection module (320-2). Accordingly, noise generation due to contact between the base layer (810) and the foldable housing (210, 220) and / or the hinge module may be prevented or reduced.

[0177] In one embodiment, referring to FIG. 13, the first cover layer (820) and the second cover layer (830) may be formed to a size that includes the deformation portion (813) of the base layer (810). In one embodiment, at least one of the first cover layer (820) and the second cover layer (830) may be formed to a size that can cover the deformation portion (813) of the base layer (810) when the deformation portion (813) is maximally extended as the electronic device (200) transitions from an unfolded state to a folded state.

[0178] According to one embodiment, as illustrated in FIG. 13, the base layer (810) may include a deformable portion (813), a first fixing portion (811) disposed on one side of the deformable portion (813), and a second fixing portion (812) disposed on the other side of the deformable portion (813). In one embodiment, the deformable portion (813) may be deformed in response to a folding operation of the electronic device (200) (e.g., the electronic device (101) of FIG. 1). In one embodiment, the first fixing portion (811) and the second fixing portion (812) may be relatively undeformed or deformed to a small degree when the deformable portion (813) is deformed in response to the folding operation of the electronic device (200).

[0179] According to one embodiment, a first adhesive member (840) may be disposed on the first fixing member (811) and the second fixing member (812) to adhere the base layer (810) to the foldable housing (e.g., the first housing (210), the second housing (220)) or the display (400) (e.g., the plates (510, 520)). In one embodiment, referring to FIG. 13, the first adhesive member (840) may be disposed on at least one of the first fixing member (811) of the base layer (810) and the second fixing member (812) of the base layer (810) to adhere the base layer (810) to the foldable housing (210, 220). In one embodiment, the first adhesive member (840) may include a first-first adhesive member (841) and a first-second adhesive member (842). In one embodiment, referring to FIG. 13, the first fixing member (811) may be fixed to the first housing (210) via the first-first adhesive member (841). The second fixing member (812) may be fixed to the second housing (220) via the first-second adhesive member (842). In this case, since the first adhesive member (840) is disposed at the lower end of the base layer (810) (e.g., in the -Z direction with reference to FIG. 13), the length of the first cover layer (820) (e.g., in the X-axis direction with reference to FIG. 13) may be longer than the length of the second cover layer (830) (e.g., in the X-axis direction with reference to FIG. 13).

[0180] In one embodiment, referring to FIG. 13, a first adhesive member (840) may be disposed on at least one of a first fixing member (811) and a second fixing member (812) of a base layer (810) to adhere the base layer (810) to the display (400). In one embodiment, the first fixing member (811) may be fixed to the first plate (510) of the display (400) via the first-first adhesive member (841). The second fixing member (812) may be fixed to the second plate (520) of the display (400) via the first-second adhesive member (842). In this case, since the first adhesive member (840) is placed on the top of the base layer (810) (e.g., in the +Z direction based on FIG. 13), the length of the first cover layer (820) (e.g., in the X-axis direction based on FIG. 13) may be shorter than the length of the second cover layer (830) (e.g., in the X-axis direction based on FIG. 13).

[0181] According to one embodiment of the present disclosure, as illustrated in FIG. 13, the base layer (810) may be fixed to the foldable housing (210, 220) or the plates (510, 520) with the first fixing portion (811) and the second fixing portion (812) centered around the deformable portion (813). In this case, when the electronic device (200) is folded, the base layer (810) may be uniformly and symmetrically extended or contracted around the folding axis (A). For example, the base layer (810) may be extended or contracted through the deformable portion (813) in response to the folding operation of the electronic device (200). In one embodiment, as the base layer (810) is uniformly extended or contracted in a symmetrical shape, the end portion (511) of the first plate (510) and the end portion (521) of the second plate (520) may be bent symmetrically with respect to the folding axis (A).

[0182] FIG. 14 is a drawing of various types of banding members arranged between a display and a foldable housing according to one embodiment of the present disclosure.

[0183] The following description may be a description of a banding member (900) of one embodiment of the banding member (600, 700, 800) described through FIGS. 6a to 13. Descriptions of configurations identical or similar to the above-described configurations will be omitted.

[0184] According to one embodiment, the banding member (900) illustrated in FIG. 14 may be formed of a non-adhesive and / or soft material, such as a rubber, urethane, or polyurethane (PU) series material (e.g., thermoplastic polyurethane (TPU)). The banding member is formed of a soft material and may be deformed in response to the folding operation of the electronic device (200) (e.g., the electronic device (101) of FIG. 1). Accordingly, the banding member (900) may expand in response to the transition of the electronic device (200) from an unfolded state to a folded state, or may contract in response to the transition of the electronic device (200) from a folded state to an unfolded state.

[0185] According to one embodiment, a first adhesive member (940) may be disposed at one end and the other end of the banding member (900) to adhere the banding member (900) to plates (510, 520) of a foldable housing (e.g., a first housing (210), a second housing (220)) or a display (400) (e.g., the first display (230) of FIGS. 2A and 4).

[0186] In one embodiment, referring to FIG. 14, a first adhesive member (940) may be disposed on at least one of one end and the other end of the banding member (900) to adhere the banding member (900) to the foldable housing (210, 220). In one embodiment, the first adhesive member (940) may include a first-first adhesive member (941) and a first-second adhesive member (942). In one embodiment, referring to FIG. 14, one end of the banding member (900) may be fixed to the first housing (210) via the first-first adhesive member (941). The other end of the banding member (900) may be fixed to the second housing (220) via the first-second adhesive member (942).

[0187] In one embodiment, referring to FIG. 14, a first adhesive member (940) may be disposed on at least one of one end and the other end of the banding member (900) to adhere the banding member (900) to the display (400). In one embodiment, referring to FIG. 14, one end of the banding member (900) may be fixed to the first plate (510) of the display (400) via the first-first adhesive member (941). The other end of the banding member (900) may be fixed to the second plate (520) of the display (400) via the first-second adhesive member (942).

[0188] According to one embodiment of the present disclosure, as illustrated in FIG. 14, the bending member (900) may be folded together with the electronic device (200) as the electronic device (200) transitions from an unfolded state to a folded state.
