Description

Electronic devices including flexible displays

[0001] Various embodiments disclosed in this document relate to electronic devices including flexible displays.

[0002] Electronic devices are becoming increasingly slimmer, more rigid, and more aesthetically pleasing, while simultaneously being developed to differentiate their functional elements. Electronic devices are evolving beyond their conventional rectangular form factor into increasingly diverse shapes. Electronic devices may have a transformable structure that allows for portability and the use of large-screen displays. Electronic devices may include rollable electronic devices (e.g., slideable electronic devices) that can vary the display area of ​​a flexible display (e.g., a rollable display) by supporting housings that slide relative to each other.

[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] The electronic device may include a rollable electronic device (e.g., a slidable electronic device) in which the display area of ​​the flexible display can be expanded and / or contracted. The rollable electronic device may include a first housing (e.g., a first housing structure, a movable structure, a slide housing, a slide bracket, or a slide structure) and a second housing (e.g., a second housing structure, a fixed structure, a base housing, a base bracket, or a base structure) that are slidably coupled to each other in a manner that is at least partially fitted together. For example, the first housing and the second housing may be configured to slide relative to each other and support at least a portion of a flexible display (e.g., an expandable display or a stretchable display), thereby inducing the flexible display to have a first display area in a slide-in state and inducing the flexible display to have a second display area larger than the first display area in a slide-out state.

[0005] A flexible display may include a plurality of layers laminated on the upper and / or lower portions of the display panel via an adhesive member (e.g., a pressure sensitive adhesive (PSA)). For example, the plurality of layers may include a first window layer (first layer, first window layer, or glass layer), a second window layer (second layer, or protective layer), or a plurality of functional layers.

[0006] Meanwhile, the flexible display may include a first portion (e.g., a flat portion) that is always visible from the outside and a second portion (e.g., a bendable portion or a bendable portion) that extends from the first portion and is accommodated in a manner that is at least partially bendable into an internal space of the electronic device when in a retracted state. An adhesive layer made of a plurality of adhesive members having different moduli may be disposed between the first window layer and the second window layer. The adhesive layer may include a first adhesive portion that corresponds at least partially to the first portion and a second adhesive portion that corresponds at least partially to the second portion when the flexible display is viewed from above. The first adhesive portion may be formed of a material that is relatively harder than the second adhesive portion so that the rigidity of the first portion that is always visible from the outside of the electronic device can be increased. The second adhesive portion may be formed of a material softer than the first adhesive portion so as to accommodate slip occurring in the plurality of layers (e.g., the first window layer, the second window layer, and / or the functional layer) constituting the flexible display when the electronic device is inserted or extracted.

[0007] When using a first adhesive portion with a high modulus to enhance the durability of a flexible display, the fluidity of the first adhesive portion may decrease when the electronic device is slid. In this case, as the stress applied to the second adhesive portion increases, the strain of the second adhesive portion may increase, increasing the likelihood of fatigue failure.

[0008] Conversely, if a first adhesive portion having a low modulus is used to reduce the possibility of fatigue failure of the second adhesive portion, the durability of the flexible display in the first portion may be reduced.

[0009] However, the problem to be solved in this disclosure is not limited to the problem mentioned above, and may be expanded in various ways without departing from the spirit and scope of this disclosure.

[0010] 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.

[0011] In one embodiment of the present disclosure, an electronic device may include a first housing, a second housing movable relative to the first housing, and a flexible display having a first portion and a second portion, wherein at least a portion of the second portion is introduced into or withdrawn from an internal space of the electronic device based on the movement of the second housing relative to the first housing. The flexible display may include at least two adhesive layers, including a first window layer, a second window layer disposed on the first window layer, and a first adhesive layer and a second adhesive layer disposed between the first window layer and the second window layer to adhere the first window layer and the second window layer. The first adhesive layer may include a first adhesive portion corresponding to a first portion of the flexible display and a second adhesive portion corresponding to the second portion of the flexible display. A modulus of the second adhesive portion may be lower than a modulus of the first adhesive portion. The modulus of the second adhesive layer may be equal to or lower than the modulus of the first adhesive portion.

[0012] According to one embodiment of the present disclosure, a flexible display, which is disposed in an electronic device in which a first housing and a second housing are movably coupled and includes a second portion at least partially introduced into or withdrawn from an internal space of the electronic device based on movement of the first portion and the second housing relative to the first housing, may include at least two adhesive layers, including a first window layer, a second window layer disposed on the first window layer, and a first adhesive layer and a second adhesive layer disposed between the first window layer and the second window layer to adhere the first window layer to the second window layer. The first adhesive layer may include a first adhesive portion corresponding to the first portion of the flexible display and a second adhesive portion corresponding to the second portion of the flexible display. A modulus of the second adhesive portion may be lower than a modulus of the first adhesive portion. The modulus of the second adhesive layer may be equal to or lower than the modulus of the first adhesive portion.

[0013] Various embodiments of the present disclosure may include an additional adhesive layer disposed between the first window layer and the second window layer. The additional adhesive layer may increase the durability of the flexible display or reduce the likelihood of damage to an adhesive member (e.g., the second adhesive portion) located on the second portion of the flexible display.

[0014] Accordingly, the flexible display of the present disclosure can have natural slip between each layer, and its durability against external impact can be improved.

[0015] 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.

[0055] A battery (189) may power at least one component of the electronic device (101). In one embodiment, the battery (189) may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0056] The communication module (190) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (101) and an external electronic device (e.g., electronic device (102), electronic device (104), or server (108)), and the performance of communication through the established communication channel. 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).

[0057] 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.

In one embodiment, the antenna module (197) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (198) or the second network (199), may be selected from the plurality of antennas, for example, by the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device via the at least one selected antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (197).

[0059] According to various embodiments, the antenna module (197) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high-frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high-frequency band.

[0060] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0061] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). 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. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (101) may provide an ultra-low latency service by using distributed computing or mobile edge computing, for example. In another embodiment, the external electronic device (104) may include an Internet of Things (IoT) device. The server (108) may be an intelligent server utilizing machine learning and / or a neural network. According to one embodiment, the external electronic device (104) or the server (108) may be included in the second network (199).The electronic device (101) can be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology and IoT-related technology.

In some embodiments, the processor (120) may detect, in real time, the movement distance while the second housing (220) is moved from the first housing (210) through the sensor module (176), and may display the movement distance on a flexible display (e.g., a flexible display (230) of FIG. 4). The display module (160) may be controlled to display an object corresponding to the changing display area. In one embodiment, the electronic device (101) may include a drive motor control module (181) for controlling the operation of a drive motor (e.g., a DC motor or a stepping motor) (e.g., the drive motor (260) of FIG. 4) disposed inside the electronic device.

[0065] Referring to FIGS. 2A to 3B , the electronic device (200) may include a first housing (210) (e.g., a book cover or a first housing structure), a second housing (220) (e.g., a front cover or a second housing structure) slidably coupled from the first housing (210) in a specified direction (e.g., direction ① or direction ②) (e.g., ± y-axis direction), and a flexible display (230) (e.g., a rollable display, an expandable display, or a stretchable display) arranged to be supported by at least a portion of the first housing (210) and the second housing (220). In one embodiment, the second housing (220) may be slidably coupled with the first housing (210) so as to be slid out in a first direction (direction ①) or slid in in a second direction (direction ②) opposite to the first direction (direction ①).

According to one embodiment, the support member (240) may include a plurality of multi-bars (241) attached at a specified interval through an adhesive layer (P) (e.g., the adhesive layer (P) of FIG. 7A) on a back surface of the support plate (460). According to one embodiment, the window layer (410), the polarizing layer (420), the display panel (430), the polymer layer (440), the support plate (460), and the support member (240) may be attached to each other via an adhesive layer (P) (e.g., an adhesive or glue). For example, the adhesive layer (P) may include a pressure sensitive adhesive (PSA), an optical clear adhesive (OCA), an optical clear resin (OCR), a heat-reactive adhesive, a general adhesive, or a double-sided tape. In one embodiment, the first adhesive layer (510), the second adhesive layers (520, 620, 720), and the third adhesive layer (630) that are attached between the first window layer (411) and the second window layer (412), which will be described later, may include a pressure sensitive adhesive (PSA), an optical clear adhesive (OCA), an optical clear resin (OCR), a heat-reactive adhesive, a general adhesive, or a double-sided tape.

In one embodiment, the second window layer (412) may be formed of a polymer (e.g., polyethylene terephthalate (PET), polyimide (PI), or thermoplastic polyurethane (TPU)). In some embodiments, the flexible display (230) may be formed as a part of the window layer (410) and may further include a coating layer disposed on top of the second window layer (412). In such a case, the coating layer may include a hard coating layer (HC layer), an anti-reflection / low reflection (AR / LR) coating layer, a shatterproof (SP) coating layer, or an anti-fingerprint (AF) coating layer.

[0098] 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 flexible display (230) may also include a touch panel (not shown).

[0099] In one embodiment, the polymer layer (440) may be disposed under the display panel (430) to provide 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 flexible display (230), the polymer layer (440) may be removed or disposed under the support plate (460).

[0100] According to one embodiment, the flexible display (230) may include at least one functional layer (450) disposed under the polymer layer (440). According to one embodiment, the functional layer (450) may include a protective layer (e.g., a TPU layer) for preventing deformation due to bending of the support member (240), a graphite sheet for heat dissipation, an added display, a force touch FPCB, a fingerprint sensor FPCB, a communication antenna radiator, a conductive / non-conductive tape, or a digitizer. According to one embodiment, the digitizer may include a plurality of conductive patterns (e.g., a dielectric film or a dielectric sheet) disposed on a dielectric substrate so as to detect a resonant frequency of an electromagnetic induction method applied from an electronic pen.

[0101] According to one embodiment, the support plate (460) can provide rigidity and bendability to the flexible display (230). For example, the support plate (460) 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 rigid properties for supporting the display panel (430). According to one embodiment, the support plate (460) can include a first region (e.g., a flat region) corresponding to a first portion (230a) of the flexible display (230) and a second region (e.g., a bending region) corresponding to a second portion (230b). According to one embodiment, the second region can include a plurality of openings arranged at a specified interval. According to one embodiment, the bending properties of the second region can 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. In some embodiments, the support plate (460) may be formed of a metal material such as SUS, Cu, Al, or a metal CLAD (e.g., a laminated member in which SUS and Al are alternately arranged). In one embodiment, the support plate (460) may help reinforce the rigidity of the electronic device (200), shield ambient noise, and may be used to disperse heat emitted from surrounding heat-emitting components.

According to one embodiment, the control circuit (4321a) may include a display driver IC (DDI) or a touch display driver IC (TDDI) mounted on the extension portion (4321) having an electrical wiring structure. According to one embodiment, the bending portion (432) may include a COP (chip on panel or chip on plastic) structure in which the control circuit (4321a) is directly disposed on the extension portion (4321). In some embodiments, the bending portion (432) may include a COF (chip on film) structure in which the control circuit (4321a) is mounted on a separate connecting film (not shown) that connects the extension portion (4321) and the flexible substrate (4322). According to one embodiment, the plurality of electrical components (4322a) may include passive components such as a touch IC, a flash memory for a display, an ESD prevention diode, a pressure sensor, a fingerprint sensor, or a decapping capacitor.

[0104] FIGS. 7A to 7C are cross-sectional views of a flexible display taken along line 5b-5b of FIG. 3A, according to one embodiment of the present disclosure. FIG. 8A is a diagram illustrating stress acting on a first adhesive layer disposed between a first window layer and a second window layer, according to one embodiment. FIG. 8B is a diagram illustrating stress acting on a first adhesive layer in a state where a second adhesive layer is disposed between the first window layer and the first adhesive layer, according to one embodiment of the present disclosure.

[0105] According to one embodiment, as illustrated in FIGS. 7A to 7C , the flexible display (230) may include a first portion (230a) (e.g., a planar portion) that is always visible from the outside in a slide-in and / or slide-out state of the electronic device and at least a portion of which is substantially flat, and a second portion (230b) (e.g., a bendable portion or a bendable portion) that extends from the first portion (230a) and is accommodated in a manner that is at least partially bent into the first space (2101) of the first housing (210) so as not to be visible from the outside in the slide-in and / or slide-out state of the electronic device. In one embodiment, at least a portion of the second portion (230b) may form a plane that is visible from the outside in a slide-in and / or slide-out state of the electronic device and is substantially parallel to the first portion (230a).

[0106] According to one embodiment, at least two adhesive layers (e.g., the first adhesive layer (510)) may be disposed between the first window layer (411) and the second window layer (412), as illustrated in FIGS. 7A to 7C. The first window layer (411) and the second window layer (412) may be attached to each other via the adhesive layers (e.g., the first adhesive layer (510) and the second adhesive layer (520)). In one embodiment, the first adhesive layer (510) may include a first adhesive portion (511) at least partially corresponding to the first portion (230a) of the flexible display (230) when the flexible display (230) is viewed from above (e.g., in the -Z direction of FIG. 7A), and a second adhesive portion (512) at least partially corresponding to the first portion (230a) and the second portion (230b) of the flexible display (230). In one embodiment, the first adhesive portion (511) and the second adhesive portion (512) may be separate components, but may also be formed integrally with each other. In one embodiment, the first adhesive portion (511) may be formed of a hard material to provide a certain level of strength to the first portion (230a) of the flexible display (230) that is always exposed to the outside. For example, the first adhesive portion (511) may be formed to have a relatively higher modulus than the second adhesive portion (512). In one embodiment, the second adhesive portion (512) may be formed of a soft material so that the slip generated in the second portion (230b) of the flexible display (230) is accommodated by the first window layer (411) and / or the second window layer (412) when the electronic device (200) is inserted or extracted. For example, the second adhesive portion (512) may be formed to have a relatively lower modulus than the first adhesive portion (511). In one embodiment, the first adhesive portion (511) may have a modulus of about 0.1 MPa to about 0.6 MPa. The second adhesive portion (512) may have a modulus of about 0.01 MPa to about 0.04 MPa.In one embodiment, the aforementioned modulus may be Young's modulus. In one embodiment, a higher modulus may result in a relatively reduced deformation due to external impact. Additionally, a higher modulus may result in a relatively stiffer material.

[0107] In one embodiment, referring to FIGS. 7A to 7C, when the second housing (220) is pulled out relative to the first housing (210), the boundary between the first adhesive portion (511) and the second adhesive portion (512) may be positioned toward the first portion (230a) in a horizontal direction with respect to the support member (240). For example, when the second housing (220) is pulled out relative to the first housing (210), the boundary between the first adhesive portion (511) and the second adhesive portion (512) may be positioned in the + Y direction of FIG. 7A with respect to the support member (240). In one embodiment, the boundary between the first portion (230a) and the second portion (230b) may be positioned in the + Y direction of FIG. 7A with respect to the support member (240).

[0108] In one embodiment, referring to FIGS. 7A to 7C, the boundaries of the first portion (230a) and the second portion (230b) and the boundaries of the first adhesive portion (511) and the second adhesive portion (512) may coincide as shown in FIG. 7A or may not coincide as shown in FIGS. 7B and 7C.

[0109] In one embodiment, referring to FIG. 7A, the first adhesive portion (511) may correspond to the first portion (230a) of the flexible display (230), and the second adhesive portion (512) may correspond to the second portion (230b) of the flexible display. In one embodiment, the boundary between the first adhesive portion (511) and the second adhesive portion (512) may coincide with the boundary between the first portion (230a) and the second portion (230b) of the flexible display (230) (e.g., line CC of FIG. 7A).

[0110] In one embodiment, referring to FIG. 7B, the second adhesive portion (512) may be positioned so that at least a portion corresponds to at least a portion of the first portion (230a) and at least a portion of the second portion (230b) of the flexible display (230). In this case, the boundary between the first adhesive portion (511) and the second adhesive portion (512) may be located in the + Y direction of FIG. 7B with respect to the boundary between the first portion (230a) and the second portion (230b) of the flexible display (230) (e.g., line CC of FIG. 7B).

[0111] In one embodiment, referring to FIG. 7c, the first adhesive portion (511) may be positioned to correspond to a portion of the first portion (230a) and the second portion (230b) of the flexible display (230). In this case, the boundary between the first adhesive portion (511) and the second adhesive portion (512) may be positioned in the -Y direction of FIG. 7c with respect to the boundary between the first portion (230a) and the second portion (230b) of the flexible display (230) (e.g., line CC of FIG. 7c).

[0112] According to one embodiment, when the electronic device (200) undergoes a sliding operation (e.g., sliding the second housing (220) relative to the first housing (210) or sliding the first housing (210) relative to the second housing (220), the adhesive layer (e.g., the first adhesive layer (510) and / or the second adhesive layer (520)) positioned between the first window layer (411) and the second window layer (412) may be elongated to accommodate the slipping of the first window layer (411) and / or the second window layer (412). For example, the first adhesive layer (510) and the second adhesive layer (520) may be elongated by stress due to a repulsive force on the plurality of layers of the flexible display (230) during the sliding operation of the electronic device (200). In one embodiment, the relatively hard first adhesive portion (511) may elongate less than the relatively soft second adhesive portion (512). Conversely, the relatively soft second adhesive portion (512) may elongate more than the relatively hard first adhesive portion (511).

[0113] In one embodiment, FIG. 8A may be a comparative example in which only the first adhesive layer (510) is disposed between the first window layer (411) and the second window layer (412). In one embodiment, referring to FIG. 8A, as the thickness (e.g., L1, the length in the Z-axis direction in FIG. 8A) of the window layer (e.g., the second window layer (412)) or the thickness of the flexible display (230) increases, the degree to which the second adhesive portion (512) must be stretched to accommodate slipping of the first window layer (411) and / or the second window layer (412) during a sliding operation of the electronic device (200) may increase. As the thickness (W1) of the second window layer (412) or the thickness of the flexible display (230) increases, the strength of the flexible display (230) may increase. However, as the thickness (W1) of the second window layer (412) or the thickness of the flexible display (230) increases, the repulsive force of the second window layer (412) or the flexible display (230) at the second portion (230b) increases during the sliding operation of the electronic device (200), so the stress applied to the second adhesive portion (512) increases, and the degree to which the second adhesive portion (512) is stretched may increase. Accordingly, the strain applied to the second adhesive portion (512) may increase. In addition, as the modulus of the first adhesive portion (511) increases, the degree to which the first adhesive portion (511) is stretched during the sliding operation of the electronic device (200) may decrease. In this case, the degree to which the second adhesive portion (512) must be elongated to accommodate slip of the first window layer (411) and / or the second window layer (412) may increase while the degree of elongation of the first adhesive portion (511) is reduced. Accordingly, the strain applied to the second adhesive portion (512) may increase as the modulus of the first adhesive portion (511) increases. As the strain applied to the second adhesive portion (512) increases, the possibility of breakage of the second adhesive portion (512) may increase.

[0114] According to one embodiment of the present disclosure, as illustrated in FIGS. 7A to 7C and 8B, the flexible display (230) may include at least two adhesive layers (e.g., a first adhesive layer (510) and a second adhesive layer (520)) bonded between a first window layer (411) and a second window layer (412). In one embodiment, compared to FIG. 8A, the flexible display (230) may include an additional adhesive layer (e.g., the second adhesive layer (520) of FIGS. 7A to 7C , the second adhesive layer (520) of FIGS. 10A to 10C , the second adhesive layer (620) of FIGS. 11A to 11C , the third adhesive layer (630) of FIGS. 11A to 11C , and / or the second adhesive layer (720) of FIGS. 12A to 12C ) disposed between the first window layer (411) and the first adhesive layer (510) in addition to the first adhesive layer (510). In one embodiment, referring to FIG. 8B, the thickness (W1) of the second window layer (412) or the thickness of the flexible display (230) may be greater than a certain value and / or the modulus of the first adhesive portion (511) may be greater than a certain value (e.g., greater than about 0.6 Mpa). In this case, an additional adhesive layer (e.g., the second adhesive layer (520) of FIGS. 7A to 7C and FIG. 8B) having a lower modulus than the first adhesive portion (511) may be disposed between the first window layer (411) and the second window layer (412) so that the strain applied to the second adhesive portion (512) can be reduced.

[0115] According to one embodiment, as illustrated in FIG. 8B, the second adhesive layer (520) may be disposed between the first window layer (411) and the first adhesive layer (510). In one embodiment, the second adhesive layer (520) may correspond to the first adhesive portion (511) and the second adhesive portion (512) when the flexible display (230) is viewed from above (e.g., in the -Z direction of FIG. 8B). In one embodiment, the second adhesive layer (520) may be adhered to the first window layer (411) and / or the first adhesive layer (510). In one embodiment, the thickness (W1) of the window layer (e.g., the first window layer (411) and / or the second window layer (412)) may be greater than or equal to a certain value (e.g., greater than or equal to about 90 micrometers) and / or the modulus of the first adhesive portion (511) may be greater than or equal to a certain value (e.g., greater than or equal to about 0.6 Mpa). In this case, a second adhesive layer (520) having a lower modulus than that of the first adhesive portion (511) may be disposed between the first adhesive layer (510) and the first window layer (411) to reduce the stress applied to the second adhesive portion (512). For example, it can be confirmed that the elongation (D'1) of the second adhesive portion (512) of FIG. 8b is reduced compared to the elongation (D1) of the second adhesive portion (512) of FIG. 8a. Therefore, the second adhesive portion (512) may have a lower possibility of being broken.

[0116] In one embodiment, the modulus of the second adhesive layer (520) illustrated in FIG. 8B may be the same as the modulus of the second adhesive portion (512). For example, the second adhesive layer (520) may be formed to have any one of values ​​from about 0.01 Mpa to about 0.04 Mpa. However, the present invention is not limited thereto, and the modulus of the second adhesive layer (520) and the modulus of the second adhesive portion (512) may have values ​​that are lower than the modulus of the first adhesive portion (511) but different from the modulus of the second adhesive portion (512). For example, the modulus of the second adhesive layer (520) may be higher than the modulus of the second adhesive portion (512), or may be lower than the modulus of the second adhesive portion (512).

[0117] In one embodiment, the modulus value of the first adhesive portion (511) that causes the breakage of the second adhesive portion (512) and / or the thickness (W1) of the second window layer (412) can also be varied.

[0118] FIG. 9A is a diagram illustrating stress acting on a first adhesive layer disposed between a first window layer and a second window layer, according to one embodiment. FIG. 9B is a diagram illustrating stress acting on a first adhesive layer in a state where a second adhesive layer is disposed between the first window layer and the first adhesive layer, according to one embodiment of the present disclosure.

[0119] In one embodiment, the thickness (W2) of the second window layer (412) of FIGS. 9A and 9B may be thinner than the thickness (W1) of the second window layer (412) of FIGS. 8A and 8B. For example, the thickness (W2) of the second window layer (412) of FIG. 9A may be about 65 micrometers or less.

[0120] According to one embodiment, as illustrated in FIG. 9A, as the thickness (W2) of the second window layer (412) or the thickness of the flexible display (230) (e.g., the length in the Z-axis direction in FIG. 9A) becomes thinner, the degree to which the second adhesive portion (512) must be stretched to accommodate slippage of the first window layer (411) and / or the second window layer (412) during the sliding operation of the electronic device (200) may be reduced, thereby reducing the possibility of breakage. In addition, as the modulus of the first adhesive portion (511) becomes lower, the degree to which the second adhesive portion (512) must be stretched to accommodate slippage of the first window layer (411) and / or the second window layer (412) during the sliding operation of the electronic device (200) may be reduced, thereby reducing the possibility of breakage. However, as the thickness (W2) of the second window layer (412) or the thickness of the flexible display (230) becomes thinner or the modulus of the first adhesive portion (511) decreases, the strength of the first portion (230a) of the flexible display (230) may decrease. Accordingly, the durability of the flexible display (230) may decrease.

[0121] According to one embodiment of the present disclosure, as illustrated in FIGS. 9A and 9B , the thickness (W2) of the second window layer (412) may be thinner than a certain value (e.g., about 65 micrometers or less) and / or the modulus of the first adhesive portion (511) may be less than a certain value (e.g., about 0.1 Mpa or less). In this case, an additional adhesive layer (e.g., the second adhesive layer (520) of FIGS. 7A to 7C , the second adhesive layer (520) of FIGS. 10A to 10C , the second adhesive layer (620) of FIGS. 11A to 11C , the third adhesive layer (630) of FIGS. 11A to 11C , and / or the second adhesive layer (720) of FIGS. 12A to 12C ) may be disposed between the first window layer (411) and the second window layer (412). In one embodiment, the additional adhesive layer may have a higher modulus than the second adhesive portion (512) so as to supplement the durability of the flexible display (230).

[0122] According to one embodiment, as illustrated in FIG. 9B, the second adhesive layer (520) may be disposed between the first window layer (411) and the first adhesive layer (510). In one embodiment, the second adhesive layer (520) may correspond to the first adhesive portion (511) and the second adhesive portion (512) when the flexible display (230) is viewed from above (e.g., in the -Z direction of FIG. 9B). In one embodiment, the second adhesive layer (520) may be adhered to the first window layer (411) and / or the first adhesive layer (510). In one embodiment, the thickness (W2) of the second window layer (412) may be thinner than or equal to a certain value (e.g., about 65 micrometers or less) and / or the modulus of the first adhesive portion (511) may be less than or equal to a certain value (e.g., about 0.1 Mpa or less). In this case, the second adhesive layer (520) is formed to have a higher modulus than the second adhesive portion (512) and can increase the strength of the flexible display (230) by being additionally placed between the first window layer (411) and the first adhesive layer (510).

[0123] In one embodiment, the elongation (D'2) of the second adhesive portion (512) of FIG. 9B may increase compared to the elongation (D2) of the second adhesive portion (512) of FIG. 9A as a second adhesive layer (520) having a higher modulus than the second adhesive portion (512) is disposed between the first adhesive layer (510) and the first window layer (411). For example, the degree to which the second adhesive portion (512) of the first adhesive layer (510) must elongate to accommodate slip of the first window layer (411) and / or the second window layer (412) may increase while the degree of elongation of the first adhesive portion (511) is reduced by the second adhesive layer (520). Accordingly, when the electronic device (200) slides, slip occurring in multiple layers of the flexible display (230) (e.g., the first window layer (411) and / or the second window layer (412)) can be accommodated.

[0124] In one embodiment, the modulus of the second adhesive layer (520) illustrated in FIG. 9B may be substantially the same as the modulus of the first adhesive portion (511). For example, the second adhesive layer (520) may be formed to have a value of any one of about 0.1 MPa to about 0.6 MPa. However, the present invention is not limited thereto, and the modulus of the first adhesive layer (510) and the modulus of the first adhesive portion (511) may have higher values ​​than the modulus of the second adhesive portion (512), but different values.

[0125] In one embodiment, the modulus value of the first adhesive portion (511) and / or the thickness (W2) of the second window layer (412) that reduces the durability of the flexible display (230) may also be varied.

[0126] FIGS. 10A to 10C are drawings showing a second adhesive layer disposed between a second window layer and a first adhesive layer according to one embodiment of the present disclosure.

[0127] In one embodiment, FIGS. 10A through 10C may be for an embodiment in which a second adhesive layer (520) is disposed between the second window layer (412) and the first adhesive layer (510), as compared to FIGS. 8B and 9B described above. In one embodiment, the function of the second adhesive layer (520) described through FIGS. 8A through 9B may be substantially identically applied to the embodiment of FIG. 10.

[0128] In one embodiment, referring to FIGS. 10A to 10C, the second adhesive layer (520) may correspond to the first adhesive portion (511) and the second adhesive portion (512) when the flexible display (230) is viewed from above (e.g., in the -Z direction of FIG. 10A). In one embodiment, the second adhesive layer (520) may be adhered to the second window layer (412) and / or the first adhesive layer (510). In one embodiment, the thickness of the second window layer (412) may be greater than or equal to a certain value (e.g., greater than or equal to about 90 micrometers) and / or the modulus of the first adhesive portion (511) may be greater than or equal to a certain value (e.g., greater than or equal to about 0.6 Mpa). In this case, the second adhesive layer (520) is formed to have a lower modulus than the first adhesive portion (511) and is placed between the first adhesive layer (510) and the second window layer (412) to reduce the stress applied to the second adhesive portion (512). Accordingly, the second adhesive portion (512) may have a lower possibility of being damaged.

[0129] In one embodiment, referring to FIGS. 10A to 10C, the thickness of the second window layer (412) may be thinner than a certain value (e.g., about 65 micrometers or less) and / or the modulus of the first adhesive portion (511) may be less than a certain value (e.g., about 0.1 Mpa or less). In this case, the second adhesive layer (520) may be formed to have a higher modulus than the second adhesive portion (512) and may be disposed between the second window layer (412) and the first adhesive layer (510) to increase the strength of the flexible display (230).

[0130] In one embodiment, referring to FIGS. 10A to 10C, when the second housing (220) is pulled out relative to the first housing (210), the boundary between the first adhesive portion (511) and the second adhesive portion (512) may be positioned toward the first portion (230a) in a horizontal direction with respect to the support member (240). For example, when the second housing (220) is pulled out relative to the first housing (210), the boundary between the first adhesive portion (511) and the second adhesive portion (512) may be positioned in the + Y direction of FIG. 10A with respect to the support member (240). In one embodiment, the boundary between the first portion (230a) and the second portion (230b) may be positioned in the + Y direction of FIG. 10A with respect to the support member (240).

[0131] In one embodiment, referring to FIG. 10A, the first adhesive portion (511) may correspond to the first portion (230a) of the flexible display (230), and the second adhesive portion (512) may correspond to the second portion (230b) of the flexible display. In one embodiment, the boundary between the first adhesive portion (511) and the second adhesive portion (512) may coincide with the boundary between the first portion (230a) and the second portion (230b) of the flexible display (230) (e.g., line CC of FIG. 10A).

[0132] In one embodiment, referring to FIG. 10b, the second adhesive portion (512) may be positioned so that at least a portion corresponds to at least a portion of the first portion (230a) and at least a portion of the second portion (230b) of the flexible display (230). In this case, the boundary between the first adhesive portion (511) and the second adhesive portion (512) may be positioned in the +Y direction of FIG. 10b with respect to the boundary between the first portion (230a) and the second portion (230b) of the flexible display (230) (e.g., line CC of FIG. 10b).

In this case, the boundary between the first adhesive portion (511) and the second adhesive portion (512) may be positioned in the -Y direction of FIG. 10c with respect to the boundary between the first portion (230a) and the second portion (230b) of the flexible display (230) (e.g., line CC of FIG. 10c).

[0134] FIGS. 11A to 11C are drawings showing a state in which a second adhesive layer, a first adhesive layer, and a third adhesive layer are laminated according to one embodiment of the present disclosure.

[0135] According to one embodiment, as illustrated in FIGS. 11A to 11C, the flexible display (230) may include a second adhesive layer (620) disposed between the second window layer (412) and the first adhesive layer (510) and a third adhesive layer (630) (e.g., the second adhesive layer (520) of FIG. 7A) disposed between the first window layer (411) and the first adhesive layer (510). In one embodiment, the second adhesive layer (620)

[0136] The first adhesive layer (510) may be disposed and / or adhered to a first surface of the first adhesive layer (510) facing the second window layer (412). In one embodiment, the third adhesive layer (630) may be disposed and / or adhered to a second surface of the first adhesive layer (510) facing the first window layer (411) and opposite the first surface. In one embodiment, the second adhesive layer (620) may correspond to the first adhesive portion (511) and the second adhesive portion (512) when the flexible display (230) is viewed from above (e.g., in the -Z direction of FIG. 11A). In one embodiment, the second adhesive layer (620) may be adhered to the second window layer (412) and / or the first adhesive layer (510). In one embodiment, the third adhesive layer (630) may correspond to the first adhesive portion (511) and the second adhesive portion (512) when the flexible display (230) is viewed from above (e.g., in the -Z direction of FIG. 11A). In one embodiment, the third adhesive layer (630) may be adhered to the first window layer (411) and / or the first adhesive layer (510).

[0137] In one embodiment, the function of the second adhesive layer (520) described through FIGS. 8A to 10C may be substantially identically applied to the second adhesive layer (620) and / or the third adhesive layer (630) of the embodiment of FIGS. 11A to 11C.

[0138] In one embodiment, referring to FIGS. 11A to 11C, the thickness of the second window layer (412) may be greater than or equal to a certain value (e.g., greater than or equal to about 90 micrometers) and / or the modulus of the first adhesive portion (511) may be greater than or equal to a certain value (e.g., greater than or equal to 0.6 MPa). In this case, the second adhesive layer (620) may be formed to have a lower modulus than the first adhesive portion (511) and may be disposed between the first adhesive layer (510) and the second window layer (412) to reduce stress applied to the second adhesive portion (512) during a sliding operation of the electronic device (200). Additionally, the third adhesive layer (630) is formed to have a lower modulus than the first adhesive portion (511) and is disposed between the first adhesive layer (510) and the first window layer (411) to reduce stress applied to the second adhesive portion (512) during a sliding operation of the electronic device (200). In one embodiment, the second adhesive layer (620) and the third adhesive layer (630) may have moduli that are equal to, higher than, or lower than the modulus of the second adhesive portion (512). The second adhesive layer (620) and the third adhesive layer (630) may have the same modulus or may have different moduli.

[0139] In one embodiment, referring to 11, the thickness of the second window layer (412) may be thinner than a certain value (e.g., about 65 micrometers or less) and / or the modulus of the first adhesive portion (511) may be less than a certain value (e.g., 0.1 MPa or less). In this case, the second adhesive layer (620) may be formed to have a higher modulus than the second adhesive portion (512) and may be disposed between the second window layer (412) and the first adhesive layer (510) to increase the strength of the flexible display (230). In addition, the third adhesive layer (630) may be formed to have a higher modulus than the second adhesive portion (512) and may be disposed between the first window layer (411) and the first adhesive layer (510) to increase the strength of the flexible display (230). In one embodiment, at least one of the second adhesive layer (620) and the third adhesive layer (630) may have a modulus equal to or lower than the modulus of the first adhesive portion (511). The second adhesive layer (620) and the third adhesive layer (630) may have the same modulus, or may have different moduli.

[0140] In one embodiment, the second adhesive layer (620) and the third adhesive layer (630) may be formed with a modulus that can reduce the possibility of damage to the second adhesive portion (512) and increase the durability of the flexible display (230). For example, the second adhesive layer (620) may have a lower modulus than the first adhesive portion (511) and / or the third adhesive layer (630) so that the stress applied to the second adhesive portion (512) during a sliding operation of the electronic device (200) can be reduced. On the other hand, the third adhesive layer (630) may have a higher modulus than the second adhesive layer (620) so that the durability of the flexible display (230) can be increased. In one embodiment, the third adhesive layer (630) may have a higher modulus than the second adhesive portion (512).

[0141] Alternatively, conversely, the second adhesive layer (620) may be formed with a higher modulus than the third adhesive layer (630) and / or the second adhesive portion (512) so that the durability of the flexible display (230) can be increased. In this case, the third adhesive layer (630) may be formed with a lower modulus than the first adhesive portion (511) and / or the second adhesive layer (620) so that the possibility of breakage of the second adhesive portion (512) can be reduced.

[0142] In one embodiment, referring to FIGS. 11A to 11C, when the second housing (220) is pulled out relative to the first housing (210), the boundary between the first adhesive portion (511) and the second adhesive portion (512) may be positioned toward the first portion (230a) in a horizontal direction with respect to the support member (240). For example, when the second housing (220) is pulled out relative to the first housing (210), the boundary between the first adhesive portion (511) and the second adhesive portion (512) may be positioned in the + Y direction of FIG. 11A with respect to the support member (240). In one embodiment, the boundary between the first portion (230a) and the second portion (230b) may be positioned in the + Y direction of FIG. 11A with respect to the support member (240).

[0143] In one embodiment, referring to FIG. 11A, the first adhesive portion (511) may correspond to the first portion (230a) of the flexible display (230), and the second adhesive portion (512) may correspond to the second portion (230b) of the flexible display. In one embodiment, the boundary between the first adhesive portion (511) and the second adhesive portion (512) may coincide with the boundary between the first portion (230a) and the second portion (230b) of the flexible display (230) (e.g., line CC of FIG. 11A).

[0144] In one embodiment, referring to FIG. 11B, the second adhesive portion (512) may be positioned so that at least a portion corresponds to at least a portion of the first portion (230a) and at least a portion of the second portion (230b) of the flexible display (230). In this case, the boundary between the first adhesive portion (511) and the second adhesive portion (512) may be located in the +Y direction of FIG. 11B with respect to the boundary between the first portion (230a) and the second portion (230b) of the flexible display (230) (e.g., line CC of FIG. 11B).

[0145] In one embodiment, referring to FIG. 11C, the first adhesive portion (511) may be positioned to correspond to a portion of the first portion (230a) and the second portion (230b) of the flexible display (230). In this case, the boundary between the first adhesive portion (511) and the second adhesive portion (512) may be positioned in the -Y direction of FIG. 11C with respect to the boundary between the first portion (230a) and the second portion (230b) of the flexible display (230) (e.g., line CC of FIG. 11C).

[0146] FIGS. 12A to 12C are drawings of an embodiment of the present disclosure in which a second adhesive layer disposed between a first adhesive layer and a first window layer is formed of a plurality of adhesive members having different moduli.

[0147] According to one embodiment, as illustrated in FIGS. 12A to 12C, the flexible display (230) may include a second adhesive layer (720) (e.g., the second adhesive layer (520) of FIG. 7A) disposed between the first adhesive layer (510) and the first window layer (411). In one embodiment, the second adhesive layer (720) may include a third adhesive portion (721) at least partially corresponding to the first portion (230a) of the flexible display (230) and a fourth adhesive portion (722) at least partially corresponding to the first portion (230a) and the second portion (230b) of the flexible display (230) when the flexible display (230) is viewed from above (e.g., in the -Z direction of FIG. 12A). In one embodiment, when the flexible display (230) is viewed from above, at least a portion of the third adhesive portion (721) may overlap the first adhesive portion (511). Additionally, at least a portion of the fourth adhesive portion (722) may overlap the second adhesive portion (512). In one embodiment, the third adhesive portion (721) and the fourth adhesive portion (722) may be separate components, but may also be formed integrally with each other. In one embodiment, the third adhesive portion (721) may be formed of a hard material to provide a certain level of strength to the first portion (230a) of the flexible display (230) that is always exposed to the outside. For example, the third adhesive portion (721) may be formed to have a relatively higher modulus than the fourth adhesive portion (722). In one embodiment, the fourth adhesive portion (722) may be formed of a material that is relatively softer than the third adhesive portion (721) so that the slip that occurs in the second portion (230b) of the flexible display (230) is accommodated when the electronic device (200) is inserted or extracted, the first window layer (411) and / or the second window layer (412).

[0148] In one embodiment, referring to FIGS. 12A to 12C, the boundary between the third adhesive portion (721) and the fourth adhesive portion (722) may be positioned toward the first portion (230a) in a horizontal direction with respect to the support member (240). For example, when the second housing (220) is pulled out with respect to the first housing (210), the boundary between the third adhesive portion (721) and the fourth adhesive portion (722) may be positioned in the + Y direction of FIG. 12A with respect to the support member (240). In one embodiment, the boundary between the first portion (230a) and the second portion (230b) may be positioned in the + Y direction of FIG. 12A with respect to the support member (240).

[0149] In one embodiment, referring to FIGS. 12A to 12C, the third adhesive portion (721) and the fourth adhesive portion (722) may correspond to the first adhesive portion (511) and the second adhesive portion (512), respectively.

[0150] In one embodiment, referring to FIG. 12A, the third adhesive portion (721) may correspond to the first portion (230a) of the flexible display (230), and the fourth adhesive portion (7222) may correspond to the second portion (230b) of the flexible display. In one embodiment, the boundary between the third adhesive portion (721) and the fourth adhesive portion (722) may coincide with the boundary between the first portion (230a) and the second portion (230b) of the flexible display (230) (e.g., line CC of FIG. 12A).

[0151] In one embodiment, referring to FIG. 12B, the second adhesive portion (512) may be arranged so that at least a portion corresponds to at least a portion of the first portion (230a) and at least a portion of the second portion (230b) of the flexible display (230). The fourth adhesive portion (722) may be arranged so that at least a portion corresponds to at least a portion of the first portion (230a) and at least a portion of the second portion (230b) of the flexible display (230), since it corresponds to the second adhesive portion (512). In this case, the boundary between the third adhesive portion (721) and the second adhesive portion (722) may be located in the +Y direction of FIG. 12B with respect to the boundary between the first portion (230a) and the second portion (230b) of the flexible display (230) (e.g., line CC of FIG. 12B).

[0152] In one embodiment, referring to FIG. 12C, the first adhesive portion (511) may be positioned to correspond to a portion of the first portion (230a) and the second portion (230b) of the flexible display (230). Since the third adhesive portion (721) corresponds to the first adhesive portion (511), at least a portion thereof may be positioned to correspond to a portion of the first portion (230a) and the second portion (230b) of the flexible display (230). In this case, the boundary between the third adhesive portion (721) and the fourth adhesive portion (722) may be positioned in the -Y direction of FIG. 12C with respect to the boundary between the first portion (230a) and the second portion (230b) of the flexible display (230) (e.g., line CC of FIG. 12C).

[0153] In one embodiment, referring to FIGS. 12A to 12C, when the thickness of the second window layer (412) is greater than or equal to a certain value (e.g., greater than or equal to about 90 micrometers) and / or the modulus of the first adhesive portion (511) is greater than or equal to a certain value, at least one of the third adhesive member (721) and the fourth adhesive member (722) may be formed to have a lower modulus than the first adhesive portion (511) and may be disposed between the first adhesive layer (510) and the second window layer (412) to reduce the stress applied to the second adhesive portion (512).

[0154] In one embodiment, referring to FIGS. 12A to 12C, when the thickness of the window layer (e.g., the first window layer (411) and / or the second window layer (412)) is thinner than a certain value (e.g., about 65 micrometers or less) and / or the modulus of the first adhesive portion (511) is less than a certain value, at least one of the third adhesive member (721) and the fourth adhesive member (722) may be formed to have a higher modulus than the second adhesive portion (512) and may be disposed between the second window layer (412) and the first adhesive layer (510) to increase the strength of the flexible display (230). For example, at least one of the third adhesive portion (721) and the fourth adhesive portion (722) of the second adhesive layer (720) may be formed to have a higher modulus than the second adhesive portion (512), thereby increasing the strength of the flexible display (230).

[0155] According to one embodiment of the present disclosure, in addition to the first adhesive layer (510), an additional adhesive layer (e.g., the second adhesive layer (520) of FIGS. 7A to 7C , the second adhesive layer (520) of FIGS. 10A to 10C , the second adhesive layer (620) of FIGS. 11A to 11C , the third adhesive layer (630) of FIGS. 11A to 11C , and / or the second adhesive layer (720) of FIGS. 12A to 12C ) may be disposed between the first window layer (411) and the second window layer (412). The additional adhesive layer may increase the durability of the flexible display or reduce the possibility of damage to the adhesive member (e.g., the second adhesive portion (512)) located in the second portion of the flexible display.

[0156] In the above description, the numerical values ​​for the modulus of the first adhesive layer (510), the second adhesive layer (520, 620, 720), the third adhesive layer (730) and / or the thickness of the second window layer (412) have been exemplarily described, but may not be limited thereto. The numerical values ​​for the modulus of the first adhesive layer (510), the second adhesive layer (520, 620), the third adhesive layer and / or the thickness of the second window layer (412) may be variously modified within a range that can be implemented by a person skilled in the art.

[0157] FIGS. 13A and 13B are front and rear views of an unfolded state of an electronic device according to an embodiment of the present disclosure. FIGS. 14A and 14B are front and rear views of a folded state of an electronic device according to an embodiment of the present disclosure.

[0158] The electronic device (800) of FIGS. 13a, 13b, 14a, and 14b below may be a foldable electronic device in which a plurality of housings (810, 820) are formed to be folded or unfolded through a hinge device. The electronic device (800) below may include the flexible display (230) described above with reference to FIGS. 6 to 12c. For example, the electronic device (800) of FIGS. 13a to 14b may include at least one of the first adhesive layer (510) of the flexible display (230) described through FIGS. 6 to 12c, the second adhesive layer (520) of FIGS. 7a to 7c, the second adhesive layer (520) of FIGS. 10a to 10c, the second adhesive layer (620) of FIGS. 11a to 11c, the third adhesive layer (630) of FIGS. 11a to 11c, and / or the second adhesive layer (720) of FIGS. 12a to 12c.

[0159] According to one embodiment, the first display (830) (e.g., a flexible display) may include the flexible display (230) of FIGS. 6 to 12C described above. In one embodiment, the first display (830) may include a window layer (410) of FIG. 6, a polarizing layer (POL (polarizer)) (420) (e.g., a polarizing film) disposed on a back surface of the window layer (410), a display panel (430), a polymer layer (440), at least one functional layer (450), and a support plate (460).

[0160] According to one embodiment, at least two adhesive layers (e.g., a first adhesive layer (510)) may be disposed between a first window layer (411) and a second window layer (412). The first window layer (411) and the second window layer (412) may be attached to each other via the adhesive layers (e.g., the first adhesive layer (510) and the second adhesive layer (520)). In one embodiment, when the first display (830) is viewed from above (e.g., in the Z direction of FIG. 13A), at least a portion of the first adhesive portion (511) of the first adhesive layer (510) may correspond to at least a portion of the first region (830a) and the second region (830b) of the first display (830), respectively. In one embodiment, the second adhesive portion (512) of the first adhesive layer (510) may correspond to the folding area (830C) of the first display (830). In one embodiment, the second adhesive portion (512) may extend at least partially from the folding area (830c) to the first area (830a) and the second area (830b). For example, when the first display (830) is viewed from above, the second adhesive portion (512) may be disposed in the folding area (830c) and at least partially extend to the first area (830a) and the second area (830b). In one embodiment, the first adhesive portion (511) may be formed of a rigid material to provide a certain level of strength to the first area (830a) and the second area (830b), which are substantially planar areas. In one embodiment, the second adhesive portion (512) may be formed of a material that is relatively softer than the first adhesive portion (511) so that the strength of the repulsive force generated in the folding area (830c) during the folding operation of the electronic device (800) can be reduced.

[0161] According to one embodiment of the present disclosure, in addition to the first adhesive layer (510), an additional adhesive layer (e.g., the second adhesive layer (520) of FIGS. 7A to 7C , the second adhesive layer (520) of FIGS. 10A to 10C , the second adhesive layer (620) of FIGS. 11A to 11C , the third adhesive layer (630) of FIGS. 11A to 11C , and / or the second adhesive layer (720) of FIGS. 12A to 12C ) may be disposed between the first window layer (411) and the second window layer (412).

The second hinge member (1002) can include a hinge device, a hinge module, a hinge plate, or a hinge assembly. The second housing (1020) and the third housing (1030) can be rotatably coupled about a second folding axis (A2) using the second hinge member (1002). According to various embodiments, one side (e.g., in the x-axis direction) of the third housing (1030) may be foldably coupled to a second side (e.g., in the -x-axis direction) of the second housing (1020).

[0191] According to one embodiment, the multi-foldable electronic device (1000) may be configured to recognize a case in which the first housing (1010) is first folded relative to the second housing (1020) via the first hinge member (1001), and the third housing (1030) is later folded relative to the second housing (1020) via the second hinge member (1002) as a normal folding order. According to various embodiments, the multi-foldable electronic device (1000) may be configured to recognize a case in which the third housing (1030) is first folded relative to the second housing (1020) via the second hinge member (1002), and the first housing (1010) is later folded relative to the second housing (1020) via the first hinge member (1001) as an abnormal folding order.

[0192] According to one embodiment, the width (w1) of the first housing (1010) in the transverse direction (e.g., in the x-axis and -x-axis directions) may be configured to be smaller than the width (w2) of the second housing (1020) in the transverse direction (e.g., in the x-axis and -x-axis directions). The width (w2) of the second housing (1020) in the transverse direction (e.g., in the x-axis and -x-axis directions) may be configured to be substantially the same as the width (w3) of the third housing (1030) in the transverse direction (e.g., in the x-axis and -x-axis directions). According to various embodiments, the width (w3) of the third housing (1030) in the transverse direction (e.g., in the x-axis and -x-axis directions) may be configured to be larger than the width (w2) of the second housing (1020) in the transverse direction (e.g., in the x-axis and -x-axis directions).

[0193] According to one embodiment, the first housing (1010) and the second housing (1020) are disposed on opposite sides of the first folding axis (A1) on which the first hinge member (1001) is disposed, and may have an asymmetrical shape with respect to the first folding axis (A1). According to various embodiments, the first housing (1010) and the second housing (1020) may also have a symmetrical shape with respect to the first folding axis (A1). The angle or distance between the first housing (1010) and the second housing (1020) may vary depending on whether the foldable electronic device (1000) is in an unfolded state, a folded state, or an intermediate state.

[0194] According to one embodiment, the second housing (1020) and the third housing (1030) are disposed on both sides with respect to the second folding axis (A2) on which the second hinge member (1002) is disposed, and may have a shape that is substantially symmetrical with respect to the second folding axis (A2). According to various embodiments, the second housing (1020) and the third housing (1030) may have an asymmetrical shape with respect to the second folding axis (A2). The angle or distance between the second housing (1020) and the third housing (1030) may vary depending on whether the foldable electronic device (1000) is in an unfolded state, a folded state, or an intermediate state.

[0195] According to one embodiment, the width (w12) of the second hinge member (1002) may be formed wider than the width (w11) of the first hinge member (1001). For example, when the first housing (1010) is folded with respect to the second housing (1020) and the third housing (1030) is folded with respect to the second housing (1020), and the third housing (1030) is placed on top of the first housing (1010), the width (w12) of the second hinge member (1002) may be formed wider than the width (w11) of the first hinge member (1001). For example, the first hinge member (1001) may include a slim hinge having a narrow width. For example, the second hinge member (1002) may include a wide hinge that is wider than the first hinge member (1001).

[0196] According to various embodiments, since the width (w12) of the second hinge member (1002) is formed wider than the width (w11) of the first hinge member (1001), when the third housing (1030) is first folded toward the second housing (1020), a portion of the second housing (1020) may come into contact with a portion of the first housing (1010). In this state, when the first housing (1010) is later folded toward the second housing (1020), the first housing (1010) may collide with a portion of the third housing (1030) and be damaged.

[0197] According to one embodiment, the flexible display (1040) can be arranged across at least a portion of the front (e.g., in the z-axis direction) of the first housing (1010), the second housing (1020), and the third housing (1030). The flexible display (1040) can be a first display, a foldable display, or a main display. According to various embodiments, a sub-display (1050) (e.g., a second display) can be arranged on the rear (e.g., in the -z-axis direction) of the third housing (1030).

[0198] In this document, the surface on which the flexible display (1040) is placed may be defined as the front side (e.g., in the z-axis direction) of the multi-foldable electronic device (1000), and the surface opposite the front side may be defined as the back side (e.g., in the -z-axis direction) of the multi-foldable electronic device (1000). The surface surrounding the space between the front side and the back side may be defined as the side surface of the multi-foldable electronic device (1000).

[0199] According to one embodiment, the flexible display (1040) may include a first display area (1040a) disposed in a first housing (1010), a second display area (1040b) disposed in a second housing (1020), and a third display area (1040c) disposed in a third housing (1030). The first display area (1040a), the second display area (1040b), and the third display area (1040c) may be integrally formed to form the flexible display (1040). According to various embodiments, when the multi-foldable electronic device (200) is in an unfolded state, the flexible display (240) may be configured to be disposed on most of the front surface (e.g., in the z-axis direction) of the multi-foldable electronic device (200). The flexible display (1040) can be transformed into a flat or curved surface in at least some areas. The divisions into the first display area (1040a), the second display area (1040b), and the third display area (1040c) of the flexible display (1040) may be exemplary physical divisions. The flexible display (1040) can be formed as a seamless, single, full screen.

[0201] According to various embodiments, when the multi-foldable electronic device (1000) is in an unfolded state, the second housing (1020) may include a third side (1021) that is connected to at least a portion of the first hinge member (1001) and the second hinge member (1002) and arranged to face the front of the multi-foldable electronic device (1000), a fourth side (1022) that faces in an opposite direction of the third side (1021), and / or a second side member (1023) that surrounds at least a portion of a second space between the third side (1021) and the fourth side (1022).

[0202] According to various embodiments, when the multi-foldable electronic device (1000) is in an unfolded state, the third housing (1030) may include a fifth side (1031) connected to at least a portion of the second hinge member (1002) and arranged to face the front of the multi-foldable electronic device (1000), a sixth side (1032) facing in an opposite direction of the fifth side (1031), and / or a third side member (1033) surrounding at least a portion of a third space between the fifth side (1031) and the sixth side (1032).

[0203] According to various embodiments, when the multi-foldable electronic device (1000) is in an unfolded state, the first side (1011), the third side (1021), and the fifth side (1031) may face substantially the same direction (e.g., the z-axis direction). When the multi-foldable electronic device (1000) is in an unfolded state, the second side (1012), the fourth side (1022), and the sixth side (1032) may face substantially the same direction (e.g., the -z-axis direction).

[0204] According to various embodiments, when the first housing (1010) and the second housing (1020) of the multi-foldable electronic device (1000) are in a folded state, the first side (1011) and the third side (1021) may be arranged to face each other. When the second housing (1020) and the third housing (1030) of the multi-foldable electronic device (1000) are in a folded state, the third side (1021) and the fifth side (1031) may be arranged to face each other.

[0205] According to various embodiments, the multi-foldable electronic device (1000) may include a recess (1045) formed to accommodate a flexible display (1040) through structural coupling of the first housing (1010), the second housing (1020), and the third housing (1030). The recess (1045) may have substantially the same size as the flexible display (1040).

[0206] According to various embodiments, when the multi-foldable electronic device (1000) is in an unfolded state, the first housing (1010), the second housing (1020), and the third housing (1030) form an angle of about 180 degrees, and the first display area (1040a), the second display area (1040b), and the third display area (1040c) of the flexible display (1040) form substantially the same plane and can be arranged to face substantially the same direction (e.g., the z-axis direction).

[0207] According to various embodiments, the first housing (1010) and the second housing (1020) may form an angle that allows them to stop at a designated folding angle between a folded state and an unfolded state (e.g., a free stop function) using the first hinge member (1001). In various embodiments, the first housing (1010) may also be rotated to move toward the rear of the second housing (1020) while being pressed in the unfolding direction (e.g., in the -z-axis direction) based on the designated inflection angle using the first hinge member (1001).

[0208] According to various embodiments, the second housing (1020) and the third housing (1030) may form an angle that allows them to stop at a designated folding angle between a folded state and an unfolded state using the second hinge member (1002). In various embodiments, the third housing (1030) may also be rotated to move toward the rear of the second housing (1020) while being pressed in an unfolding direction (e.g., along the -z-axis direction) based on the designated inflection angle using the second hinge member (1002).

[0209] According to various embodiments, the flexible display (1040) may be arranged to be supported by the first side (1011) of the first housing (1010), the first hinge member (1001), the third side (1021) of the second housing (1020), the second hinge member (1002), and the fifth side (1031) of the third housing (1030).

[0215] FIG. 16 is a schematic diagram illustrating a state in which a first housing of a multi-foldable electronic device according to an embodiment of the present invention is folded relative to a second housing. FIG. 17 is a schematic diagram illustrating a state in which a first housing and a third housing of a multi-foldable electronic device according to an embodiment of the present invention are folded relative to a second housing.

[0216] According to one embodiment, FIG. 16 may be a drawing of a multi-foldable electronic device (1000) in a state where the first housing (1010) is folded toward the second housing (1020) as viewed in the -y-axis direction. According to one embodiment, FIG. 17 may be a drawing of a multi-foldable electronic device (1000) in a state where the first housing (1010) is folded toward the second housing (1020) first and the third housing (1030) is folded toward the second housing (1020) later (e.g., a normal folding order) as viewed in the -y-axis direction.

[0217] Referring to FIGS. 16 and 17, the multi-foldable electronic device (1000) may include a first housing (1010), a second housing (1020), a third housing (1030), a first hinge member (1001), and a second hinge member (1002).

[0218] In one embodiment, the first housing (1010) may first be folded over the top (e.g., in the z-axis direction) of the second housing (1020) via a first hinge member (1001) (e.g., a slim hinge).

[0219] In one embodiment, after the first housing (1010) is folded toward the second housing (1020) via the first hinge member (1001), the third housing (1030) can be folded toward the second housing (1020) via the second hinge member (1002) (e.g., a wide hinge) and placed on top (e.g., in the z-axis direction) of the first housing (1010).

[0220] According to one embodiment, the multi-foldable electronic device (1000) can recognize as a normal folding order a case in which the first housing (1010) is first folded toward the second housing (1020) through the first hinge member (1001), and the third housing (1030) is later folded toward the second housing (1020) through the second hinge member (1002). According to various embodiments, the multi-foldable electronic device (1000) can recognize as an abnormal folding order a case in which the third housing (1030) is first folded toward the second housing (1020) through the second hinge member (1002), and the first housing (1010) is later folded toward the second housing (1020) through the first hinge member (1001).

[0221] In one embodiment, the first hinge member (1001) may have a first width (w11). The second hinge member (1002) may have a second width (w12). The second width (w12) may be wider than the first width (w11). In various embodiments, since the first housing (1010) is folded relative to the second housing (1020) and the third housing (1030) is folded relative to the second housing (1020), and the third housing (1030) should be positioned on top (e.g., in the z-axis direction) of the first housing (1010), the second width (w12) of the second hinge member (1002) may be formed wider than the first width (w11) of the first hinge member (1001). For example, the first hinge member (1001) may include a slim hinge having a narrow width. For example, the second hinge member (1002) may include a wide hinge having a wider width than the first hinge member (1001).

[0222] According to various embodiments, since the second width (w12) of the second hinge member (1002) is formed wider than the first width (w11) of the first hinge member (1001), when the third housing (1030) is first folded toward the second housing (1020), a portion of the second housing (1020) may come into contact with a portion of the first housing (1010). In this state, when the first housing (1010) is later folded toward the second housing (1020), the first housing (1010) may collide with a portion of the third housing (1030) and be damaged.

[0223] In one embodiment, the multi-foldable electronic device (1000) may be folded in a sequence (e.g., a normal folding sequence) in which the first housing (1010) is folded first toward the second housing (1020), and the third housing (1030) is folded later toward the second housing (1020). This can reduce the risk of breakage.

[0224] According to various embodiments, the multi-foldable electronic device (1000) may provide at least one notification (e.g., a warning sound, vibration, and / or pop-up message) to the user when the third housing (1030) is folded first toward the second housing (1020) and the first housing (1010) is folded later toward the second housing (1020) in an abnormal folding order (e.g., an abnormal folding order).

[0225] According to various embodiments, the multi-foldable electronic device (1000) described above is described assuming that the first housing (1010) is folded inward toward the second housing (1020) and the third housing (1030) is folded inward toward the second housing (1020), but may not be limited thereto. In one embodiment, the multi-foldable electronic device (1000) may be configured such that the first housing (1010) is outfolded with respect to the second housing (1020), such that a portion (e.g., a folding area (1040d)) of a flexible display (1040) disposed in the first housing (1010) and the second housing (1020) is bent by 180 degrees or more, and a first display area (1040a) of the flexible display (1040) disposed in the first housing (1010) is exposed to the outside. In this case, the third housing (1030) may be folded in an infolding manner toward the second housing (1020), so that the second display area (1040b) and the third display area (1040c) may face each other and not be exposed to the outside of the electronic device (1000). Conversely, the third housing (1030) may be folded outward with respect to the second housing (1020), so that a portion (e.g., folding area (1040e)) of the flexible display (1040) disposed in the second housing (1020) and the third housing (1030) may be bent by more than 180 degrees, and the third display area (1040c) of the flexible display (1040) disposed in the third housing (1030) may be exposed to the outside. In this case, the first housing (1010) is folded in an infolding manner toward the second housing (1020), so that the first display area (1040a) and the second display area (1040b) face each other and are not exposed to the outside of the electronic device (1000).
