Furthermore, for clarity and brevity, well-known functions and configurations are not described in the drawings and related descriptions.

[0046] Figure 1 This is a block diagram illustrating an electronic device 101 in a network environment 100 according to various embodiments. (Refer to...) Figure 1Electronic device 101 in network environment 100 can communicate with at least one of the following: electronic device 102 via a first network 198 (e.g., a short-range wireless communication network), or electronic device 104 or server 108 via a second network 199 (e.g., a long-range wireless communication network). According to an embodiment, electronic device 101 can communicate with electronic device 104 via server 108.

[0047] Processor 120 may run software (e.g., program 140) to control at least one other component (e.g., hardware or software component) of electronic device 101 connected to processor 120, and may perform various data processing or calculations. According to embodiments, as at least part of the data processing or calculations, processor 120 may store commands or data received from another component (e.g., sensor module 176 or communication module 190) in volatile memory 132, process the commands or data stored in volatile memory 132, and store the resulting data in non-volatile memory 134.

For example, in the case where electronic device 101 includes a main processor 121 and an auxiliary processor 123, the auxiliary processor 123 may be configured to consume less power than the main processor 121, or may be configured to be dedicated to a specific function. The auxiliary processor 123 may be implemented separately from the main processor 121, or may be implemented as a part of the main processor 121.

[0048] When the main processor 121 is inactive (e.g., in sleep mode), the auxiliary processor 123 (rather than the main processor 121) can control at least some of the functions or states associated with at least one component of the electronic device 101 (e.g., display module 160, sensor module 176, or communication module 190), or when the main processor 121 is active (e.g., running an application), the auxiliary processor 123 can work with the main processor 121 to control at least some of the functions or states associated with at least one component of the electronic device 101 (e.g., display module 160, sensor module 176, or communication module 190). According to embodiments, the auxiliary processor 123 (e.g., an image signal processor or a communication processor) may be implemented as part of another component (e.g., camera module 180 or communication module 190) functionally associated with the auxiliary processor 123. According to embodiments, the auxiliary processor 123 (e.g., a neural processing unit) may include hardware architecture dedicated to artificial intelligence model processing.

[0052] The audio output module 155 can output audio signals to the outside of the electronic device 101. The audio output module 155 may include, for example, a speaker or a receiver. The speaker can be used for general purposes such as playing multimedia or playing records. The receiver can be used to receive incoming calls. According to embodiments, the receiver can be implemented separately from the speaker or as part of the speaker.

[0053] Display module 160 can visually provide information to the outside of electronic device 101 (e.g., to a user). Display device 160 may include, for example, a display, a holographic device, or a projector, and control circuitry for controlling a respective one of the display, holographic device, and projector. According to an embodiment, display module 160 may include a touch sensor configured to detect a touch or a pressure sensor configured to measure the intensity of the force generated by the touch.

[0054] The audio module 170 can convert sound into electrical signals and vice versa.

[0055] Sensor module 176 can detect the operating state of electronic device 101 (e.g., power or temperature) or the state of the external environment (e.g., the user's state), and then generate an electrical signal or data value corresponding to the detected state. According to embodiments, sensor module 176 may include, for example, a gesture sensor, a gyroscope sensor, an atmospheric pressure sensor, a magnetic sensor, an accelerometer, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

According to an embodiment, the haptic module 179 may include, for example, a motor, a piezoelectric element, or an electrical stimulator.

[0059] Camera module 180 can capture still or moving images. According to an embodiment, camera module 180 may include one or more lenses, an image sensor, an image signal processor, or a flash.

[0060] The power management module 188 manages the power supply to the electronic device 101. According to an embodiment, the power management module 188 may be implemented as at least part of, for example, a power management integrated circuit (PMIC).

[0061] Battery 189 can power at least one component of electronic device 101. According to embodiments, battery 189 may include, for example, a non-rechargeable primary battery, a rechargeable rechargeable battery, or a fuel cell.

[0062] Communication module 190 can support the establishment of a direct (e.g., wired) or wireless communication channel between electronic device 101 and external electronic devices (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. Communication module 190 may include one or more communication processors capable of operating independently of processor 120 (e.g., application processor (AP)) and supporting direct (e.g., wired) or wireless communication. According to embodiments, communication module 190 may include wireless communication module 192 (e.g., cellular communication module, short-range wireless communication module, or Global Navigation Satellite System (GNSS) communication module) or wired communication module 194 (e.g., local area network (LAN) communication module or power line communication (PLC) module). A corresponding one of these communication modules can communicate via a first network 198 (e.g., a short-range communication network, such as Bluetooth). TM The wireless communication module 192 can communicate with external electronic devices 104 via a Wi-Fi Direct or Infrared Data Association (IrDA) network or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a local area network (LAN) or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip) or as multiple components separate from each other (e.g., multiple chips). The wireless communication module 192 can use user information (e.g., an International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196 to identify or verify electronic devices 101 in a communication network (such as a first network 198 or a second network 199).

[0063] Wireless communication module 192 can support 5G networks following 4G networks and next-generation communication technologies (such as new radio (NR) access technologies). NR access technologies can support enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), or ultra-reliable low-latency communication (URLLC). Wireless communication module 192 can support high-frequency bands (e.g., millimeter-wave bands) to achieve, for example, high data transmission rates. Wireless communication module 192 can support various technologies used to ensure performance in high-frequency bands, such as, for example, beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, or massive antennas. Wireless communication module 192 can support various requirements specified in electronic device 101, external electronic device (e.g., electronic device 104), or network system (e.g., second network 199). According to an embodiment, the wireless communication module 192 may support peak data rates (e.g., 20 Gbps or greater) for implementing eMBB, lost coverage (e.g., 164 dB or less) for implementing mMTC, or U-plane latency (e.g., 0.5 ms or less for each of the downlink (DL) and uplink (UL), or 1 ms or less round trip) for implementing URLLC.

[0064] Antenna module 197 can transmit or receive signals or power to or from an external source (e.g., an external electronic device). According to an embodiment, antenna module 197 may include an antenna comprising a radiator formed of a conductor or conductive pattern on a substrate (e.g., a printed circuit board (PCB)). According to an embodiment, antenna module 197 may include multiple antennas (e.g., an antenna array). In this case, at least one antenna suitable for a communication scheme used in a communication network (such as a first network 198 or a second network 199) can be selected from the multiple antennas by, for example, communication module 190. Signals or power can then be transmitted or received between communication module 190 and external electronic device via the selected at least one antenna. According to an embodiment, other components besides the radiator (e.g., a radio frequency integrated circuit (RFIC)) may also be formed as part of antenna module 197.

[0065] According to various embodiments, antenna module 197 may form a millimeter-wave antenna module. According to embodiments, the millimeter-wave antenna module may include a printed circuit board, a radio frequency integrated circuit (RFIC), and multiple antennas (e.g., an array antenna), wherein the RFIC is disposed on or adjacent to a first surface (e.g., a bottom surface) of the printed circuit board and is capable of supporting a specified high-frequency band (e.g., a millimeter-wave band), and the multiple antennas are disposed on or adjacent to a second surface (e.g., a top surface or a side surface) of the printed circuit board and are capable of transmitting or receiving signals in the specified high-frequency band.

[0066] At least some of the aforementioned components can be interconnected and communicate signals (e.g., commands or data) between them via an inter-peripheral communication scheme (e.g., bus, general purpose input / output (GPIO), serial peripheral interface (SPI), or mobile industrial processor interface (MIPI)).

[0067] According to an embodiment, commands or data can be sent or received between electronic device 101 and external electronic device 104 via server 108 connected to a second network 199. External electronic device 102 or electronic device 104 may each be a device of the same type as electronic device 101, or a device of a different type. According to an embodiment, all or some operations to be performed on electronic device 101 may be performed on one or more of external electronic device 102, external electronic device 104, or server 108. For example, if electronic device 101 is required to automatically perform a function or service, or is required to perform a function or service in response to a request from a user or another device, electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service, instead of running the function or service, or electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service in addition to running the function or service. Upon receiving the request, the one or more external electronic devices may perform the requested at least portion of the function or service, or perform additional functions or services related to the request, and transmit the result of the execution to electronic device 101. Electronic device 101 may provide the result as at least a partial response to the request, with or without further processing of the result. For this purpose, technologies such as cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing may be used. Electronic device 101 may use, for example, distributed computing or mobile edge computing to provide ultra-low latency services. In another embodiment, external electronic device 104 may include Internet of Things (IoT) devices. Server 108 may be an intelligent server using machine learning and / or neural networks. According to embodiments, external electronic device 104 or server 108 may be included in a second network 199. Electronic device 101 can be applied to intelligent services (e.g., smart homes, smart cities, smart cars, or healthcare) based on 5G communication technology or IoT-related technologies.

[0068] The electronic device according to various embodiments of this disclosure can be one of a variety of types of electronic devices. Electronic devices may include, for example, portable communication devices (e.g., smartphones), computer equipment, portable multimedia devices, portable medical devices, cameras, wearable devices, or home appliances. According to embodiments of this disclosure, the electronic device is not limited to those described above.

[0069] Figure 2A This is a perspective view showing a foldable electronic device in an unfolded state according to an embodiment. Figure 2B This is a perspective view showing a foldable electronic device in a folded state according to an embodiment. Figure 3This is an exploded view illustrating a foldable electronic device according to an embodiment. Figures 2A to 3 The electronic devices shown are for illustrative purposes only, and this disclosure is not limited to the accompanying drawings. Figures 2A to 3 The XYZ coordinate system shown is for illustrative purposes to describe the layout of the components and does not limit the scope of the claims.

[0070] Electronic device 200 (e.g., Figure 1 The electronic device 101 may include at least a pair of housings 210 and 220. The pair of housings 210 and 220 may be rotatably coupled to fold relative to each other, for example, around a hinge while facing each other (e.g., Figure 3 The hinge 240 folds the shell. For example, a pair of housings 210 and 220 may include a first housing 210 and a second housing 220. The first housing 210 and the second housing 220 may be disposed on two opposite sides of the folding axis F. An end region of the first housing 210 and an end region of the second housing 220 may be disposed side by side, with the hinge 240 between them. The first housing 210 and the second housing 220 may have a shape symmetrical with respect to a plane including the folding axis F and extending in the Z1 axis direction. Here, the folding axis F may be an axis in the X1 direction formed by the hinge 240.

[0071] The first housing 210 may have substantially the same length as the second housing 220 (e.g., length in the Y1 axis direction), but is not limited thereto. The first housing 210 may have substantially the same width as the second housing 220 (e.g., width in the X1 axis direction), but is not limited thereto.

[0072] In the following text, "unfolded state (or flat state)" or "unfolded state" may refer to a state in which the angle between the first housing 210 and the second housing 220 is substantially 180 degrees. "Folded state" or "folded state" may refer to a state in which the angle formed between the first housing 210 and the second housing 220 is substantially 0 degrees. "Intermediate state" may refer to any state between the unfolded state and the folded state. For example, the electronic device 200 may rotate about the hinge 240 such that the first housing 210 and the second housing 220 form an angle from 0 degrees to 180 degrees. The electronic device 200 may rotate about the hinge 240 such that the first housing 210 and the second housing 220 form an angle, for example, from 180 degrees to 360 degrees.

[0073] The first housing 210 may include a first surface 210a and a second surface 210b. For example, the first surface 210a may be configured to face a first direction (e.g., the +Z1 axis direction). The first surface 210a may be, for example, a surface on which at least a portion of the flexible display 230 is disposed. The first surface 210a may refer to, for example, a virtual surface overlapping with at least a portion of the flexible display 230. For example, the second surface 210b may be configured to face a second direction (e.g., the -Z1 axis direction). The second surface 210b may be, for example, a surface on which a first back cover 212 is disposed. The second surface 210b may be parallel to the first surface 210a. The second surface 210b may refer to a plane defined by, for example, the first back cover 212.

[0074] The second housing 220 may include a third surface 220a and a fourth surface 220b. For example, the third surface 220a may be configured to face a first direction (e.g., the +Z1 axis direction). The third surface 220a may be, for example, a surface on which at least a portion of the flexible display 230 is disposed. The third surface 220a may refer to, for example, a virtual surface overlapping with at least a portion of the flexible display 230. For example, the fourth surface 220b may be configured to face a second direction (e.g., the -Z1 axis direction). The fourth surface 220b may be, for example, a surface on which a second rear cover 222 is disposed. The fourth surface 220b may be parallel to the third surface 220a. The fourth surface 220b may refer to a plane defined by, for example, the second rear cover 222.

[0075] When the electronic device 200 is deployed, the first surface 210a and the third surface 220a can be positioned within an arbitrary virtual plane (e.g., the X1-Y1 plane). For example, when the electronic device 200 is deployed, the first surface 210a and the third surface 220a can form the same plane. For example, the first surface 210a and the third surface 220a can be configured to form a 180-degree angle with respect to the X1-Y1 plane in the deployed state. When the electronic device 200 is deployed, the second surface 210b and the fourth surface 220b can be positioned within another arbitrary virtual plane (e.g., the X1-Y1 plane). For example, the second surface 210b and the fourth surface 220b can form the same plane in the deployed state of the electronic device 200. For example, the second surface 210b and the fourth surface 220b can be configured to form a 180-degree angle with respect to the X1-Y1 plane in the deployed state.

[0076] In the folded state of the electronic device 200, at least a portion of the first surface 210a and at least a portion of the third surface 220a can face each other. For example, in the folded state of the electronic device 200, the angle between the first surface 210a and the third surface 220a can be 0 degrees with respect to the X1-Y1 plane. As the electronic device 200 folds from the unfolded state, the angle between the first surface 210a and the third surface 220a and the X1-Y1 plane can gradually decrease. For example, in an intermediate state, the angle formed between the first surface 210a and the third surface 220a and the X1-Y1 plane can be determined to be between approximately 0 degrees and approximately 180 degrees. In the folded state of the electronic device 200, the second surface 210b and the fourth surface 220b can be parallel to each other. For example, the second surface 210b and the fourth surface 220b can face opposite directions in the folded state of the electronic device 200.

[0077] The pair of housings 210 and 220 included in the electronic device 200 are not limited to the shape and connection shown, but may be implemented in other shapes or via the combination and / or connection of other components.

[0096] Figure 4This is a perspective view showing the stacked structure of a flexible display according to an embodiment.

[0097] Figure 4 The flexible display 400 shown can be at least partially similar to the electronic device described above (e.g., Figure 2A Flexible displays in electronic devices 200 (e.g., Figure 2A Flexible display 230).

[0098] According to an embodiment, one of the housings (e.g., Figure 2A The first housing 210) is relative to another housing (e.g., Figure 2A The second housing 220) of the electronic device 200, which moves in various shape factors, may include Figure 4 The flexible display 400 shown is illustrated.

[0099] According to an embodiment, the flexible display 400 can be configured to at least traverse the first housing 210 and the second housing 220. Therefore, when the second housing 220 moves relative to the first housing 210, at least a portion of the flexible display 400 can be bent.

[0100] According to an embodiment, the flexible display 400 may include flexible regions and non-flexible regions. The flexible and non-flexible regions can be configured in various shapes and numbers according to the shape factor of the electronic device 200 on which the flexible display 400 is mounted. A flexible region may refer to an area that bends according to the electronic device 200. A non-flexible region may refer to areas other than the flexible regions, i.e., areas that do not bend or maintain a flat surface.

[0101] Reference Figure 4 The flexible display 400 may include a protective member 410 (e.g., a protective film), a glass member 420, and a display panel 430. According to an embodiment, the flexible display 400 may be configured such that the protective member 410, the glass member 420, and the display panel 430 are stacked sequentially from top to bottom. Each component may be bonded together by adhesive members P1, P2, but this disclosure is not limited thereto.

[0102] The adhesive components P1 and P2 may include at least one of optically clear adhesive (OCA) film, optically clear resin (OCR), pressure-sensitive adhesive (PSA) film, thermally reactive adhesive, general-purpose adhesive, and double-sided tape. The adhesive components P1 and P2 may include photocurable adhesives or thermosetting adhesives, and their materials are not particularly limited. The adhesive components P1 and P2 may include, for example, at least one of a first adhesive component P1 and a second adhesive component P2, wherein the first adhesive component P1 is configured to bond the protective component 410 and the glass component 420, and the second adhesive component P2 is configured to bond the glass component 420 and the display panel 430.

[0103] The first adhesive member P1 may be configured to be attached to at least a portion of the upper surface of the glass member 420. The second adhesive member P2 may be configured to be attached to at least a portion of the lower surface of the glass member 420. However, it is not limited thereto; as described below, the first adhesive member P1 may be attached to a portion of the upper surface of the glass member 420, and the second adhesive member P2 may be attached to the remaining portion of the upper surface of the glass member 420. Adhesive members with different physical properties may be arranged around the glass member 420 in various ways and structures.

[0104] Figure 4 The configuration shown is for ease of description, and the flexible display 400 may also include additional configurations. For example, although not shown, various types of layers, such as a touch sensing layer, may be disposed above the display panel 430. The touch sensing layer may be configured to receive coordinate information from external input. The touch sensing layer may be, for example, a capacitive touch sensing element. However, this is not limited to this, and other types of touch sensing layers, including two types of touch electrodes, may be reconfigured, such as electromagnetic induction methods.

[0105] According to an embodiment, the display panel 430 may be disposed below the glass member 420. The display panel 430 may be disposed, for example, below the glass member 420, wherein the polarizing layer 450 is interposed between the display panel 430 and the glass member 420. The display panel 430 may be an organic light-emitting display panel, an electrophoretic display panel, an electrowetting display panel, or a quantum dot display panel, but the type is not limited. The light-emitting layer of an organic light-emitting display panel may include organic light-emitting materials. The light-emitting layer of a quantum dot display panel may include quantum dots and quantum rods. The display panel 430 may be formed such that at least a portion thereof is flexible. For example, the display panel 430 may be formed such that at least a portion thereof is deformable.

[0106] According to an embodiment, the flexible display 400 may include a polarizing layer 450. The polarizing layer 450 may be disposed on the display panel 430. For example, the polarizing layer 450 may be disposed between the glass member 420 and the display panel 430. The polarizing layer 450 can reduce the external light reflectivity of the flexible display 400 by absorbing or destructively interfering with externally incident light. For example, the polarizing layer 450 may be integrally formed with the display panel 430 through a continuous process. For example, the polarizing layer 450 may be a component of the display panel 430. When the polarizing layer 450 and the display panel 430 are integrally formed, the adhesive members therebetween can be omitted. When the polarizing layer 450 is manufactured separately and attached to the display panel 430, it can be attached using adhesive members.

[0107] According to an embodiment, the glass component 420 may be disposed above the display panel 430. The glass component 420 may be attached by an adhesive component to directly contact the display panel 430. However, it is not limited to this, and various types of layers such as a polarizing layer 450 or a touch sensing layer (not shown) may be disposed between the glass component 420 and the display panel 430.

[0108] According to embodiments, the glass member 420 can have various shapes to enhance the rigidity of the edge portions in the flexible region 400b. The edge portions of the glass member 420 corresponding to the flexible region 400b can be formed with multiple recesses (e.g., Figure 8 Multiple recesses 830 or Figure 10 The glass member 420 may have multiple recesses 1040, or may be formed to have a greater thickness than other parts. The glass member 420 may have various structures in the edge portions to prevent or reduce breakage in the flexible region 400b, and will be described in detail later.

[0109] According to an embodiment, a protective member 410 (e.g., a protective film) may be disposed on the uppermost layer of the flexible display 400. The protective member 410 may be disposed above the glass member 420 to protect the glass member 420 from external impacts. The protective member 410 can protect the glass member 420 from external impacts and, in the event of breakage of the glass member 420, help prevent or reduce the scattering of glass fragments.

[0110] The protective member 410 and the glass member 420 can be bonded together by the first adhesive member P1. When the protective member 410 and the glass member 420 are bonded together, the first adhesive member P1 can be disposed between the protective member 410 and the glass member 420.

[0111] According to an embodiment, the protective member 410 can be detachably attached to the glass member 420. In the event of damage to the protective member 410 from an external impact, a new protective member 410 can be attached to the glass member 420. Therefore, the adhesive force of the first adhesive member P1 can be weaker than the adhesive force of the second adhesive member P2.

[0112] According to embodiments, the protective member 410 may include, but is not limited to, polyethylene terephthalate (PET) or polyimide (PI), and may include the material used for the glass member 420 or polymer member 460, which will be described below. For example, the thickness of the protective member 410 may be substantially the same as or relatively thinner than the thickness of the glass member 420. As an example, the protective member 410 may be omitted from the configuration of the flexible display 400. If the protective member 410 is omitted, the first adhesive member P1 may also be omitted.

[0113] According to an embodiment, the flexible display 400 may include a polymer member 460 disposed below the display panel 430. The polymer member 460 may, for example, have an applied dark color to help display the background when the display is off. The polymer member 460 may, for example, serve as a cushioning member to absorb impacts from outside the electronic device to prevent or reduce damage to the flexible display 400.

[0114] The polymer component 460 may include a plastic film as a base layer. The polymer component may include a plastic film comprising any one selected from the group consisting of polyethersulfone (PES), polyacrylate (PAR), polyetherimide (PEI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polyarylate, polyimide (PI), polycarbonate (PC), or combinations thereof.

[0115] Although not shown, a metal sheet layer may be disposed beneath the display panel 430. The metal sheet layer helps enhance the rigidity of the electronic device. It can be used, for example, to shield ambient noise and dissipate heat emitted from surrounding heat-generating components. The metal sheet layer may include at least one of stainless steel (STS), Cu, Al, or other alloy materials.

[0116] According to an embodiment, the flexible display 400 may further include a printed layer 440. The printed layer 440 may be disposed in a portion of the flexible display 400. For example, the printed layer 440 may be disposed near the edge of the protective member 410. For example, the printed layer 440 may be disposed along the edge of the protective member 410. As an example, the printed layer 440 may extend along the edge of the protective member 410 to have a substantially rectangular shape. For example, the printed layer 440 may be disposed along the edge of the protective member 410. The printed layer 440 may be disposed on the upper or lower surface of the protective member 410. However, it is not limited thereto; the printed layer 440 may also be disposed on the upper or lower surface of the glass member 420.

[0117] However, not limited to this, unlike what is shown, the printed layer 440 may also be disposed along the edge of the glass member 420. For example, the printed layer 440 may also be disposed on the upper or lower surface of the glass member 420.

[0118] According to an embodiment, the printed layer 440 may be disposed on the flexible display 400 in an electronic device (e.g., Figure 2A The boundary of the display area visible from the outside in the state of the electronic device 200 (e.g., a black matrix (BM) printed layer). The printed layer 440 may be formed along the peripheral portion of the protective member 410, but this disclosure is not limited thereto. For example, the printed layer 440 may form a border pattern. The printed layer 440 may include, for example, a light-blocking material that is not light-transmitting.

[0119] The printed layer 440 may have a width of, for example, 2.5 mm or less, but this disclosure is not limited thereto.

[0120] Figure 5 It is a cross-sectional view taken along the peripheral portion of the electronic device according to the embodiment.

[0121] Figure 5 The structure shown is a schematic diagram for describing a foreign body intrusion structure, and this disclosure is not limited thereto. For ease of description, it is shown schematically. Figure 5 The structure shown, and Figure 5 The shape does not limit the scope of the rights disclosed herein.

[0122] refer to Figure 5 The electronic device 200 may include a flexible display 400, a protective cap 510, and a housing 210 or 220.

[0123] According to an embodiment, a protective cap 510 may be disposed between the flexible display 400 and the housing 210 or 220 to prevent or reduce the entry of foreign objects between the flexible display 400 and the housing 210 or 220. The protective cap 510 may be configured to contact an edge portion of the flexible display 400. The protective cap 510 may be formed, for example, of a rubber material, but this disclosure is not limited thereto.

[0124] Due to the size differences of each component, steps can be formed on the side of the flexible display 400. As an example, the side of the glass member 420 can be positioned inward between the protective member 410 and the display panel 430 to form a concave space.

[0125] When using the electronic device 200, foreign objects may enter between the flexible display 400 and the protective cap 510. In particular, when the electronic device 200 is bent, a tiny gap is formed between the protective cap 510 and the flexible display 400, and foreign objects may enter through this gap.

[0126] Foreign objects entering between the flexible display 400 and the protective cap 510 may damage the glass component 420.

[0127] As an example, if a foreign object is positioned at the first location D1 as shown in the figure, the glass component 420 may break. Here, the first location D1 may refer to the space between the protective component 410 and the protective cap 510. With the foreign object positioned at the first location D1, if a force is applied from above to press down on the protective cap 510, the glass component 420 may break due to the stress applied to the foreign object. For example, through electronic devices (e.g., Figure 2AForeign objects positioned in a first position during the folding and / or unfolding operation of the electronic device 200 can be subjected to a pressing load in the direction toward the flexible display 400 by being pressed by the protective cap 510. This may cause breakage starting from the protective member 410 in contact with the foreign object, and in addition, high stress may be transmitted to the glass member 420, thereby causing damage to the glass member 420 and the display panel 430.

[0128] As an example, if a foreign object is located at the second position D2 as shown in the figure, the glass component 420 may break. The second position D2 can refer to a location adjacent to the glass component 420 in the empty space between the side of the flexible display 400 and the housing 210 or 220. A foreign object located at the second position D2 may cause a small crack on the side of the glass component 420 by directly contacting it. This small crack may occur due to factors such as… Figure 2A The stress caused by the folding operation or external impact of the electronic device 200 can eventually cause the glass component 420 to break.

[0129] This disclosure presents structures for glass member 420 according to various embodiments, thereby reducing breakage of glass member 420. A detailed description of glass member 420 according to various embodiments is provided later.

[0134] Reference Figure 6 and Figure 7 The glass member 600 can be configured such that at least a portion thereof is deformable. For example, the glass member 600 may include a non-flexible region 600a and a flexible region 600b. Here, the non-flexible region 600a of the glass member 600 may correspond to... Figure 4 Non-flexible regions (e.g., Figure 4 The non-flexible region 400a). Here, the flexible region 600b of the glass member 600 can correspond to Figure 4 Flexible regions (e.g., Figure 4 Flexible region 400b).

[0135] According to an embodiment, the glass component 600 may include a first side surface 601, a second side surface 602 extending vertically from the first side surface 601, a third side surface 603 extending vertically from the second side surface 602 and parallel to the first side surface 601, and a fourth side surface 604 extending vertically from the third side surface 603 and parallel to the second side surface 602.

The first glass portion 610 may include a region within a predetermined distance from the edge of the glass member 600. For example, the first glass portion 610 may include a region within a predetermined distance from the edge of the glass member 600 included in the flexible region 600b. For example, the first glass portion 610 may include a region within a predetermined interval from the edge portion of the glass member 600 corresponding to the edge portion of the flexible region 600b. For example, the first glass portion 610 may include a region within a predetermined interval from a portion of a side surface of the glass member 600 (e.g., the second side surface 602 or the fourth side surface 604). Here, the predetermined interval may be 1 mm or less, but this disclosure is not limited thereto.

[0138] According to an embodiment, the glass component 600 is included Figure 4 In the case of the flexible display 400, the first glass portion 610 can be positioned therewith in relation to the printed layer (e.g., Figure 4The overlapping position of a portion of the printed layer 440. The first glass portion 610 can be positioned so that it is visually hidden by the printed layer 440.

[0139] According to an embodiment, the first glass portion 610 may have a vertically symmetrical structure. However, it is not limited to this and may have a shape that further protrudes from at least one of the upper or lower sides. According to an embodiment, the first glass portion 610 may have a shape that protrudes from at least one of the upper or lower sides. For example, one of the upper or lower sides may have a non-protruding shape.

[0140] According to an embodiment, the second glass portion 620 may be a portion different from the first glass portion 610. The second glass portion 620 may include at least a portion of the glass member 600 other than the first glass portion 610.

[0141] According to an embodiment, the thickness of the first glass portion 610 can be made relatively thicker than the thickness of the second glass portion 620. For example, the thickness of the first glass portion 610 can be greater than the average thickness of the glass member 600. The rigidity of the first glass portion 610 can be relatively stronger than the rigidity of the second glass portion 620. The thickness difference between the first glass portion 610 and the second glass portion 620 can be formed by an etching process using chemicals, but the manufacturing method is not limited to this.

[0142] According to an embodiment, the first glass portion 610 can be positioned therewith. Figure 5 The protective cap shown (e.g., Figure 5 Protective cap 510) and protective components (e.g., Figure 5 The overlapping area of ​​at least a portion of the contact area of ​​the protective member 410. By forming a first glass portion 610 that is relatively thicker than the second glass portion 620, even if a foreign object is stuck... Figure 5 The first position (e.g., Figure 5 In the case of the first position D1), damage caused by foreign objects can also be effectively prevented or reduced.

[0143] According to an embodiment, the glass component 600 may include a third glass portion 630. The third glass portion 630 may be positioned between the first glass portion 610 and the second glass portion 620. The third glass portion 630 may be the portion connecting the first glass portion 610 and the second glass portion 620.

[0144] The third glass portion 630 may be formed to slope upward from the second glass portion 620 toward the first glass portion 610. The third glass portion 630 may also be formed to slope downward from the first glass portion 610 toward the second glass portion 620. However, it is not limited to this, and unlike what is shown, the third glass portion 630 may form a step based on the thickness difference between the first glass portion 610 and the second glass portion 620.

[0146] Figure 8 and Figure 9 The glass component 800 shown may include in Figure 4 The flexible display shown (e.g., Figure 4 In the flexible display 400). Figure 8 and Figure 9 The glass component 800 shown can be with Figure 4 The glass components shown (e.g., Figure 4 The glass components (420) have a substantially the same or similar configuration. Alternatively, Figure 8 and Figure 9 The glass component 800 shown can be replaced Figure 4 The flexible display shown (e.g., Figure 4 The glass components in the flexible display 400 (e.g., Figure 4 Glass component 420).

[0147] exist Figure 9 For ease of description, the thickness of the glass component 800 may be shown in slightly exaggerated form.

[0148] Figure 8 and Figure 9 The embodiments can be selectively associated with Figures 1 to 7 Examples of combinations. Figure 8 and Figure 9 The embodiments can be selectively associated with Figures 10 to 33C Examples of combinations.

[0149] Reference Figure 8 and Figure 9 The glass member 800 can be configured such that at least a portion thereof is deformable. For example, the glass member 800 may include a non-flexible region 800a and a flexible region 800b. Here, the non-flexible region 800a of the glass member 800 may correspond to... Figure 4 Non-flexible regions (e.g., Figure 4The non-flexible region 400a). Here, the flexible region 800b of the glass member 800 can correspond to Figure 4 Flexible regions (e.g., Figure 4 Flexible region 400b).

[0150] According to an embodiment, the glass component 800 may include a first side surface 801, a second side surface 802 extending vertically from the first side surface 801, a third side surface 803 extending vertically from the second side surface 802 and parallel to the first side surface 801, and a fourth side surface 804 extending vertically from the third side surface 803 and parallel to the second side surface 802.

[0151] According to an embodiment, the glass component 800 may include a first glass portion 810 and a second glass portion 820.

[0152] According to an embodiment, the first glass portion 810 may include a portion adjacent to the edge of the glass member 800. The first glass portion 810 may include a region within a predetermined distance from the edge of the glass member 800. For example, the first glass portion 810 may include a region within a predetermined distance from the edge of the glass member 800 included in the flexible region 800b. For example, the first glass portion 810 may include a region within a predetermined interval from the edge portion of the glass member 800 corresponding to the edge portion of the flexible region 800b. For example, the first glass portion 810 may include a region within a predetermined interval from a portion of a side surface of the glass member 800 (e.g., the second side surface 802 or the fourth side surface 804). Here, the predetermined interval may be 1 mm or less, but this disclosure is not limited thereto.

[0153] In glass component 800 included Figure 4 In the case of the flexible display 400, the first glass portion 810 can be positioned therewith in relation to the printed layer (e.g., Figure 4 The overlapping position of a portion of the printed layer 440. The first glass portion 810 can be positioned so that it is visually hidden by the printed layer 440.

[0154] The second glass portion 820 may be a portion different from the first glass portion 810. The second glass portion 820 may include at least a portion of the glass member 800 other than the first glass portion 810.

[0155] According to an embodiment, the glass member 800 may include a plurality of recesses 830. The plurality of recesses 830 may be formed to be recessed inward from an edge or side surface of the glass member 800. For example, the plurality of recesses 830 may be formed inward from the outside (or from its edge) of the glass member 800 on at least one side surface of the glass member 800. The plurality of recesses 830 may be formed near an edge corresponding to a flexible region 800b of the glass member 800. For example, the plurality of recesses 830 may be formed to be recessed inward from an edge or side surface corresponding to a flexible region 800b. The plurality of recesses 830 may be formed to perpendicularly penetrate the glass member 800, but this disclosure is not limited thereto. The plurality of recesses 830 may be disposed adjacent to a first glass portion 810. The plurality of recesses 830 may be formed by physical processing methods, laser processing methods, or chemical etching methods, but this disclosure is not limited thereto.

[0156] According to an embodiment, a plurality of recesses 830 may be formed around the first glass portion 810. For example, the first glass portion 810 may have a comb-like shape due to the plurality of recesses 830, but the present disclosure is not limited thereto. For example, the first glass portion 810 may be disposed between two adjacent recesses 830.

[0157] According to an embodiment, the plurality of recesses 830 may be configured to be spaced apart at a predetermined interval. For example, the plurality of recesses 830 may be configured to be spaced apart at a predetermined interval along the length direction of the glass member 800. Here, the length direction of the glass member 800 may refer to the length direction of the second side surface 802. Here, the predetermined interval may be within 1 micrometer to 1 millimeter, but this disclosure is not limited thereto. For example, the depth L2 of the plurality of recesses 830 may be within 1 micrometer to 1 millimeter, but this disclosure is not limited thereto. For example, the width L1 of the plurality of recesses 830 may be within 1 micrometer to 1 millimeter, but this disclosure is not limited thereto.

[0158] According to an embodiment, the plurality of recesses 830 may include a first recess 830-1 and a second recess 830-2. The first recess 830-1 and the second recess 830-2 may be disposed adjacent to each other. The first recess 830-1 and the second recess 830-2 may be spaced apart, wherein the first glass portion 810 is positioned between the first recess 830-1 and the second recess 830-2. The first recess 830-1 and the second recess 830-2 may be substantially the same in size or shape, but this disclosure is not limited thereto.

[0159] Since each of the plurality of recesses 830 is formed with a small size of less than 1 mm, it is possible to prevent or reduce the impact of the plurality of recesses 830 on the display panel (e.g., Figure 4 The display panel 430) is subjected to direct impact. For example, even when force is applied to a flexible display (e.g., Figure 4In the case of the first glass portion 810 side of the flexible display 400, the force will not be released from the protective member (e.g., Figure 4 The protective component 410) is applied directly to the display panel (e.g., Figure 4 The display panel 430 has a generally comb-shaped first glass portion 810 that can protect the display panel 430.

[0160] According to an embodiment, the spacing L3 between the plurality of recesses 830 can vary even within the flexible region 800b. According to an embodiment, the spacing between the plurality of recesses 830 can vary as they approach the center of the flexible region 800b (e.g., ...). Figure 3 The folding axis F becomes smaller.

[0161] According to an embodiment, when the first glass portion 810 of the glass member 800 has a generally comb-like shape due to the plurality of recesses 830, damage to the glass member 800 due to the intrusion of foreign objects can be prevented or reduced. For example, even if a foreign object enters... Figure 5 The second position (e.g., Figure 5 In the case of the second position D2), by reducing the side surface area of ​​the first glass portion 810, the possibility of foreign objects contacting the side surface of the glass component 800 can also be reduced.

[0162] Even when a foreign object comes into contact with the first glass portion 810 of the glass member 800 and a crack appears on the side surface of the first glass portion 810, the generally comb-shaped structural features can prevent or reduce the propagation of the crack to the entire area of ​​the glass member 800. Even when the flexible region 800b of the glass member 800 is bent, the stress applied to the first glass portion 810 can be relatively reduced due to the generally comb-shaped first glass portion 810. In other words, since the stress applied to the first glass portion 810 with multiple recesses 830 during bending is relatively small compared to glass without multiple recesses 830, crack propagation can be prevented or reduced.

[0163] Figure 10 This is a view showing a glass component according to an embodiment. Figure 11 It is along Figure 10 A cross-sectional view taken from the CC line.

[0164] Figure 10 and Figure 11 The glass component 1000 shown may be included in Figure 4 The flexible display shown (e.g., Figure 4 In the flexible display 400). Figure 10 and Figure 11 The glass component 1000 shown can be with Figure 4 The glass components shown (e.g., Figure 4 The glass components (420) have a substantially the same or similar configuration. Alternatively, Figure 10 and Figure 11 The glass component 1000 shown can be replaced Figure 4 The flexible display shown (e.g., Figure 4 The glass components in the flexible display 400 (e.g., Figure 4 Glass component 420).

[0165] exist Figure 11 For ease of description, the thickness of the glass component 1000 can be shown in slightly exaggerated form.

[0166] Figure 10 and Figure 11 The embodiments can be selectively associated with Figures 1 to 9 Examples of combinations. Figure 10 and Figure 11 The embodiments can be selectively associated with Figures 12 to 33C Examples of combinations.

[0167] Reference Figure 10 and Figure 11 The glass member 1000 can be configured such that at least a portion thereof is deformable. For example, the glass member 1000 may include a non-flexible region 1000a and a flexible region 1000b. Here, the non-flexible region 1000a of the glass member 1000 may correspond to... Figure 4 Non-flexible regions (e.g., Figure 4 The non-flexible region 400a). Here, the flexible region 1000b of the glass member 1000 can correspond to Figure 4 Flexible regions (e.g., Figure 4 Flexible region 400b).

[0168] According to an embodiment, the glass component 1000 may include a first side surface 1001, a second side surface 1002 extending vertically from the first side surface 1001, a third side surface 1003 extending vertically from the second side surface 1002 and parallel to the first side surface 1001, and a fourth side surface 1004 extending vertically from the third side surface 1003 and parallel to the second side surface 1002.

[0169] According to an embodiment, the glass component 1000 may include a first glass portion 1010 and a second glass portion 1020.

[0170] According to an embodiment, the first glass portion 1010 may include a portion adjacent to the edge of the glass member 1000. The first glass portion 1010 may include a region within a predetermined distance from the edge of the glass member 1000. For example, the first glass portion 1010 may include a region within the flexible region 1000b within a predetermined distance from the edge of the glass member 1000 included in the flexible region 1000b. For example, the first glass portion 1010 may include a region within a predetermined interval from the edge portion of the glass member 1000 corresponding to the edge portion of the flexible region 1000b. For example, the first glass portion 1010 may include a region within a predetermined interval from a portion of a side surface of the glass member 1000 (e.g., a second side surface 1002 or a fourth side surface 1004). Here, the predetermined interval may be 1 mm or less, but this disclosure is not limited thereto.

[0171] In the glass component 1000, including Figure 4 In the case of the flexible display 400, the first glass portion 1010 can be positioned therewith in relation to the printed layer (e.g., Figure 4 The overlapping position of a portion of the printed layer 440. The first glass portion 1010 can be positioned to be visually hidden by the printed layer 440.

[0172] According to an embodiment, the first glass portion 1010 may have a vertically symmetrical structure. However, it is not limited to this and may have a shape that further protrudes from at least one of the upper or lower sides. According to an embodiment, the first glass portion 1010 may have a shape that protrudes from at least one of the upper or lower sides. For example, one of the upper or lower sides may have a non-protruding shape.

[0173] The second glass portion 1020 may be a portion different from the first glass portion 1010. The second glass portion 1020 may include at least a portion of the glass member 1000 other than the first glass portion 1010.

[0174] According to an embodiment, the thickness of the first glass portion 1010 can be made relatively thicker than the thickness of the second glass portion 1020. For example, the thickness of the first glass portion 1010 can be thicker than the average thickness of the glass member 1000. The rigidity of the first glass portion 1010 can be relatively stronger than the rigidity of the second glass portion 1020. The thickness difference between the first glass portion 1010 and the second glass portion 1020 can be formed by an etching process using chemicals, but the manufacturing method is not limited to this.

[0175] According to an embodiment, the first glass portion 1010 can be positioned therewith. Figure 5 The protective cap shown (e.g., Figure 5 Protective cap 510) and protective components (e.g., Figure 5The overlapping location of at least a portion of the area in contact with the protective member 410. By forming a first glass portion 1010 that is relatively thicker than the second glass portion 1020, even if a foreign object is stuck... Figure 5 The first position (e.g., Figure 5 In the case of the first position D1), damage caused by foreign objects can also be effectively prevented or reduced.

[0176] According to an embodiment, the glass member 1000 may include a plurality of recesses 1040. The plurality of recesses 1040 may be formed to be recessed inward from an edge or side surface of the glass member 1000. For example, the plurality of recesses 1040 may be formed inward from the outside (or from its edge) of at least one side surface of the glass member 1000. The plurality of recesses 1040 may be formed near an edge corresponding to a flexible region 1000b of the glass member 1000. For example, the plurality of recesses 1040 may be formed to be recessed inward from an edge or side surface corresponding to a flexible region 1000b. The plurality of recesses 1040 may be disposed adjacent to a first glass portion 1010. The plurality of recesses 1040 may be formed by physical processing methods, laser processing methods, or chemical etching methods, but this disclosure is not limited thereto.

[0177] According to an embodiment, a plurality of recesses 1040 may be formed around the first glass portion 1010. For example, the first glass portion 1010 may have a comb-like shape due to the plurality of recesses 1040, but this disclosure is not limited thereto.

[0178] According to an embodiment, the plurality of recesses 1040 may be configured to be spaced apart at predetermined intervals. For example, the plurality of recesses 1040 may be configured to be spaced apart at predetermined intervals along the length direction of the glass member 1000. Here, the length direction of the glass member 1000 may refer to the length direction of the second side surface 1002. Here, the predetermined interval may be within 1 micrometer to 1 millimeter, but this disclosure is not limited thereto. For example, the depth L2 of the plurality of recesses 1040 may be within 1 micrometer to 1 millimeter, but this disclosure is not limited thereto. For example, the width L1 of the plurality of recesses 1040 may be within 1 micrometer to 1 millimeter, but this disclosure is not limited thereto.

[0179] According to an embodiment, the plurality of recesses 1040 may include a first recess 1040-1 and a second recess 1040-2. The first recess 1040-1 and the second recess 1040-2 may be disposed adjacent to each other. The first recess 1040-1 and the second recess 1040-2 may be configured to be spaced apart, wherein the first glass portion 1010 is positioned between the first recess 1040-1 and the second recess 1040-2. The first recess 1040-1 and the second recess 1040-2 may be substantially the same in size or shape, but this disclosure is not limited thereto.

[0180] Because each of the plurality of recesses 1040 is formed with a small size of less than 1 mm, direct impact on the display panel 430 by the plurality of recesses 1040 can be prevented or reduced. For example, even when force is applied to a flexible display (e.g., Figure 4 In the case of the first glass portion 1010 side of the flexible display 400, the force will not be released from the protective member (e.g., Figure 4 The protective component 410) is applied directly to the display panel (e.g., Figure 4 The display panel 430 has a generally comb-shaped first glass portion 1010 that can protect the display panel 430.

[0181] According to an embodiment, even within the flexible region 1000b, the spacing L3 between the plurality of recesses 1040 can vary. According to an embodiment, the spacing between the plurality of recesses 1040 can vary as they approach the center of the flexible region 1000b (e.g., ...). Figure 3 The folding axis F becomes smaller.

[0182] According to an embodiment, when the first glass portion 1010 of the glass member 1000 has a generally comb-like shape due to the plurality of recesses 1040, damage to the glass member 1000 due to the intrusion of foreign objects can be prevented or reduced. For example, even if a foreign object enters... Figure 5 The second position (e.g., Figure 5 In the case of the second position D2), by reducing the side surface area of ​​the first glass portion 1010, the possibility of foreign objects contacting the side surface of the glass component 1000 can also be reduced.

[0183] Even if a foreign object comes into contact with the first glass portion 1010 of the glass member 1000 and a crack appears on the side surface of the first glass portion 1010, the generally comb-shaped structural features can prevent the crack from propagating to the entire area of ​​the glass member 1000. Even if the flexible region 1000b of the glass member 1000 is bent, the stress applied to the first glass portion 1010 can be relatively reduced by having a generally comb-shaped first glass portion 1010. In other words, since the stress applied to the first glass portion 1010 with multiple recesses 1040 during bending is relatively small compared to glass without multiple recesses 1040, crack propagation can be prevented or reduced.

[0184] According to an embodiment, the glass component 1000 may include a third glass portion 1030. The third glass portion 1030 may be positioned between the first glass portion 1010 and the second glass portion 1020. The third glass portion 1030 may be the portion connecting the first glass portion 1010 and the second glass portion 1020.

[0185] The third glass portion 1030 may be formed to slope from the second glass portion 1020 toward the first glass portion 1010. The third glass portion 1030 may also be formed to slope downward from the first glass portion 1010 toward the second glass portion 1020. However, not limited thereto, unlike what is shown, the third glass portion 1030 may form a step based on the thickness difference between the first glass portion 1010 and the second glass portion 1020.

[0186] Figure 12 This is a cross-sectional view showing a flexible display according to an embodiment.

[0187] Figure 12 The illustration shows the inclusion of Figure 10 and Figure 11 The figure shows a partial cross-sectional view of the flexible display 1200 of the glass component 1000. In the following, the same reference numerals are used for the arrangement around the glass component 1000 and for reference. Figure 4 The configurations described are basically the same.

[0188] Figure 12 The embodiments can be selectively associated with Figures 1 to 11 Examples of combinations. Figure 12 The embodiments can be selectively associated with Figures 13 to 33C Examples of combinations.

[0189] Reference Figure 12 The protective member 410 can be attached or joined to the upper surface of the glass member 1000. The glass member 1000 can be attached or joined to the protective member 410 via the first adhesive member P1. The thickness of the portion of the first adhesive member P1 that contacts the first glass portion 1010 can be less than the thickness of the portion of the first adhesive member P1 that contacts the second glass portion 1020.

[0190] Display panel 430 or polarizing layer (e.g., Figure 4 The polarizing layer 450 can be attached or bonded to the lower surface of the glass component 1000. The glass component 1000 can be attached or bonded to the display panel 430 via the second adhesive member P2. The thickness of the portion of the second adhesive member P2 that contacts the first glass portion 1010 can be less than the thickness of the portion of the second adhesive member P2 that contacts the second glass portion 1020.

[0191] Figure 13 This is a view showing the magnitude of the stress applied during bending of a flexible display according to an embodiment.

[0192] Figure 13 (a) is a diagram where multiple recesses are not formed at the edge of the glass component. Figure 13 (b) is a diagram showing multiple recesses formed at the edge of a glass component. Figure 13(b) may be shown Figure 8 Glass components (e.g., Figure 8 Glass components 800) or Figure 10 Glass components (e.g., Figure 10 A view of the bending stress values ​​of a glass component (1000). Figure 13 The glass component shown in (a) and Figure 13 The glass components shown in (b) are substantially the same except that they have multiple recesses.

[0193] exist Figure 13 (a) and Figure 13 In (b), the shadows are shown to be darker as the bending stress increases during bending.

[0194] Compare Figure 13 (a) and Figure 13 (b) It is possible to identify the difference in the magnitude of the stress applied to the edges (or corners) during the bending of the glass component. In the case of forming multiple recesses, the magnitude of the stress applied to the edge portions of the glass component can be reduced. Therefore, as referenced Figure 5 As described, even if a foreign object enters the second position D2 and causes a crack on the edge of the glass member 1000, the stress applied during bending is reduced, thereby preventing or reducing the propagation of the crack.

[0195] As an example, in Figure 13 In case (a), the maximum stress applied to the edge can be 655.2 MPa. As an example, in Figure 13 In case (b), the maximum stress applied to the edge can be 510.2 MPa. By forming multiple recesses, it can be identified that the magnitude of the maximum stress applied to the edge during the bending of the glass component is reduced by approximately 22%.

[0196] Figure 14 This is a graph showing the strength of the glass component according to the thickness of the embodiment. Figure 15 This is a graph showing the relative repulsive force according to the thickness of the glass component in accordance with an embodiment.

[0197] Reference Figure 14 It can be identified that the strength of the glass component generally increases with increasing thickness. Here, "pen drop" can refer to the height from which the pen breaks if it is dropped from a predetermined distance above. Pen pressure is the force applied to the glass component when the pen is pressed down, and the value of the pen pressure can increase with increasing strength of the glass component. It can be identified that the strength of the glass component generally increases with increasing thickness.

[0198] For example, in the case of glass components with a thickness of 60 micrometers or more, it can be identified that pen drop and pen pressure show an increase in strength of more than 1.9 times and 2.8 times, respectively, compared to a thickness of 30 micrometers.

[0199] Reference Figure 15 The repulsive force can increase with the thickness of the glass component. For example, with a glass component thickness of 60 micrometers or more, the repulsive force can increase by about 8 times or more compared to a thickness of 30 micrometers. High repulsive forces can lead to a deterioration in the folding performance of the glass component.

[0200] Therefore, as Figure 6 or Figure 10 As shown, even in the first glass section ( Figure 6 First glass section 610 or Figure 10 When the thickness of the first glass portion 610 is increased to enhance rigidity, an appropriate thickness must also be set so that the repulsive force does not increase excessively. As an example, the thickness of the first glass portions 610 and 1010 can be 30 micrometers to 60 micrometers, but this disclosure is not limited thereto.

[0201] Figure 16 This is an example used to describe a method for forming multiple recesses in a glass component.

[0202] Figure 16 It shows the method for forming in Figure 8 Glass components (e.g., Figure 8 Glass components 800) or Figure 10 Glass components (e.g., Figure 10 Multiple recesses (e.g., in the glass component 1000) formed in the glass component 1000 Figure 8 Multiple recesses 830 or Figure 10 One of the methods (multiple recesses 1040).

[0203] Reference Figure 16 Multiple recesses 830, 1040 can be formed by stacking multiple glass components 1610 and etching the edges of the stacked glass components 1600. The locations where the recesses are to be formed in the stacked glass components 1600 can be physically etched using an etching tool C. The etching tool C can be, for example, a computer numerical control (CNC) tool. The etching tool C can include, for example, a diamond tip or a micro-grinding wheel.

[0204] Figure 17A and Figure 17B This is an example used to describe a method for forming multiple recesses in a glass component.

[0205] Figure 17A and Figure 17B It shows the method for forming in Figure 8Glass components (e.g., Figure 8 Glass components 800) or Figure 10 Glass components (e.g., Figure 10 Multiple recesses (e.g., in the glass component 1000) formed in the glass component 1000 Figure 8 Multiple recesses 830 or Figure 10 One of the methods (multiple recesses 1040).

[0206] Reference Figure 17A and Figure 17B Multiple recesses 830 and 1040 can be formed through chemical etching. First, as... Figure 17A As shown, a process can be performed to cause a phase transition in the portion 1720 to be etched in the glass component 1710. For example, a Bessel beam can be used to cause a phase transition in the portion 1720 to be etched, but this disclosure is not limited thereto.

[0207] After the portion 1720 to be etched undergoes a phase transformation, multiple recesses 1730 can be formed by exposing the glass component 1710 to the etching solution, such as... Figure 17B As shown. Various types of acidic or alkaline solutions can be used as etching solutions. For example, etching solutions may include ammonium fluoride, sulfuric acid, nitric acid, silicon fluoride, sodium oxide, or hydrofluoric acid.

[0208] Figure 18 This is a flowchart illustrating a method for manufacturing a flexible display according to an embodiment.

[0209] Use includes Figure 10 The flexible display of the glass component 1000 shown is described as an example. Figure 18 The manufacturing method is described above, but it can also be applied or adjusted in the case of manufacturing flexible displays that include glass components according to various other embodiments. Figure 18 The manufacturing method. Figure 18 The manufacturing method describes some of the processes involved in the manufacturing of flexible displays.

[0210] See Figure 18 A method for manufacturing a flexible display may include a process 1810 of forming a plurality of recesses in a partial region at the edge of a substrate glass. The plurality of recesses 1040 can be formed by physical etching or chemical etching. For example, it can be formed by referring to... Figures 16 to 17B The physical or chemical etching method described is used to form multiple recesses 1040.

[0211] According to an embodiment, a method for manufacturing a flexible display may include a process 1820 of masking a specific area and performing chemical etching. Here, the specific area may be a first glass portion 1010 or a third glass portion 1030 of the glass member 1000. By chemically etching the unmasked area, a thickness difference in the glass member 1000 can be formed. For example, the third glass portion 1030 may be appropriately masked so that only a portion is etched. The second glass portion 1020 is not masked and may be etched to be thinner overall. Through process 1820, a thickness difference can be formed between the first glass portion 1010, the second glass portion 1020, and the third glass portion 1030.

For example, protective components (e.g., Figure 4 The protective member 410 can be attached to the portion of the third adhesive member 2530 and the first adhesive member 2510 on the upper side of the glass member 1000. For example, a display panel (e.g., Figure 4 The display panel 430 can be attached to a portion of the third adhesive member 2530 and the second adhesive member 2520 on the underside of the glass member 1000.

[0279] According to an embodiment, the adhesive force of the second adhesive member 2520 may be relatively greater than the adhesive force of the first adhesive member 2510. However, this disclosure is not limited thereto.

[0280] According to an embodiment, the elastic modulus (e.g., modulus) of the third adhesive member 2530 may be greater than that of the first adhesive member 2510 or the second adhesive member 2520. The third glass portion 1030, positioned between the first glass portion 1010 and the second glass portion 1020, may be a vulnerable portion prone to breakage because stress may concentrate during bending. Therefore, rigidity can be supplemented by applying a third adhesive member 2530 with a large modulus value around the first glass portion 1010 and the third glass portion 1030.

Figure 26 The application process and structure of the adhesive component shown can also be applied to... Figure 6 Glass components (e.g., Figure 6 Glass components 600) and Figure 8 Glass components (e.g., Figure 8 Glass components 800).

[0283] In the case of glass members 600, 1000, and 1900 according to various embodiments of the present disclosure, steps may occur when the members are laminated using existing methods. For example, when the members are laminated on the upper and lower surfaces of glass member 1000 using existing methods, steps may occur in the adhesive member due to the thickness difference between the first glass portions 610, 1010, and 1910 and the second glass portions 620, 1020, and 1920. Due to the steps in the adhesive member, spaces may be created when the glass member 1000 is attached to surrounding components. Alternatively, visibility may be degraded due to the steps in the adhesive member. In this disclosure, methods and structures for addressing steps or visibility issues are provided.

[0288] According to an embodiment, the protective member 2610 may have a stepped structure. According to an embodiment, the protective member 2610 may have a portion that protrudes downwards. For example, the protective member 2610 may have a portion that protrudes toward the glass member 1000. The stepped portion 2611 may be formed on the underside of the protective member 2610 via a protruding surface. The stepped portion 2611 formed in the protective member 2610 may compensate for steps in the glass member 1000.

[0289] According to an embodiment, the refractive index of the protective member 2610 may be substantially the same as the refractive index of the first adhesive member P1.

The glass component 2720 may be bonded to the protective component 410 via a first adhesive component P1. The glass component 2720 may be bonded to the display panel 430 via a second adhesive component P2.

[0294] According to an embodiment, the glass component 2720 may include a first glass portion 2721, a second glass portion 2722, and a third glass portion 2723.

[0295] According to an embodiment, the first glass portion 2721 may include a portion adjacent to the edge of the glass member 2720. The first glass portion 2721 may include a region within a predetermined distance from the edge of the glass member 2720. For example, the first glass portion 2721 may include a region within the flexible region 400b (e.g., within the flexible region). Figure 4 The flexible region 400b) includes a region within a predetermined distance from the edge of the glass member 2720. For example, the first glass portion 2721 may include a region within a predetermined interval from the edge portion of the glass member 2720 corresponding to the edge portion of the flexible region 400b. Here, the predetermined interval may be 1 mm or less, but this disclosure is not limited thereto.

[0296] The second glass portion 2722 may be a portion different from the first glass portion 2721. The second glass portion 2722 may include at least a portion of the glass member 2720 other than the first glass portion 2721.

[0297] According to an embodiment, the thickness of the first glass portion 2721 can be made relatively thicker than the thickness of the second glass portion 2722. For example, the thickness of the first glass portion 2721 can be greater than the average thickness of the glass member 2720. The rigidity of the first glass portion 2721 can be relatively stronger than the rigidity of the second glass portion 2722. The thickness difference between the first glass portion 2721 and the second glass portion 2722 can be formed by an etching process using chemicals, but the manufacturing method is not limited to this.

[0298] According to an embodiment, the first glass portion 2721 may be formed to protrude to one side. The first glass portion 2721 may be formed to protrude downwards. Therefore, the upper surface 2720a of the glass member 2720 may be flat, and the lower surface 2720b of the glass member 2720 may have a downwardly protruding portion. By forming the upper surface 2720a of the glass member 2720 to be flat, the adhesion between the glass member 2720 and the protective member 410 can be enhanced.

[0299] According to an embodiment, the third glass portion 2723 may be disposed between the first glass portion 2721 and the second glass portion 2722. The third glass portion 2723 may be the portion connecting the first glass portion 2721 and the second glass portion 2722.

[0300] According to an embodiment, the third glass portion 2723 may be formed to slope from the second glass portion 2722 toward the first glass portion 2721 on the lower surface 2720b of the glass member 2720. The third glass portion 2723 may also be formed to slope downwards from the first glass portion 2721 toward the second glass portion 2722. However, not limited thereto, unlike what is shown, the third glass portion 2723 may form a step based on the thickness difference between the first glass portion 2721 and the second glass portion 2722.

[0304] According to an embodiment, the second housing 2820 can be housed within the first housing 2810. The second housing 2820 can be coupled to the first housing 2810 to slide relative to the first housing 2810. When the second housing 2820 slides away from the first housing 2810, the display area of ​​the flexible display 2830 can expand. When the second housing 2820 slides closer to the first housing 2810, the display area of ​​the flexible display 2830 can decrease. Here, the display area can refer to the area of ​​the flexible display 2830 that is visually visible from the outside of the slidable electronic device 2800.

[0305] According to an embodiment, a portion of the flexible display 2830 may be housed within a first housing 2810 or a second housing 2820. When the second housing 2820 slides outward relative to the first housing 2810, a portion of the flexible display 2830 housed within the first housing 2810 or the second housing 2820 may be pulled outward.

The non-flexible region 2830a may be an area that is always visually exposed regardless of movement of the second housing 2820. The flexible region 2830b may be an area that can be received within the first housing 2810 or the second housing 2820. The flexible region 2830b may have a visually exposed area that varies according to movement of the second housing 2820.

[0307] According to an embodiment, the flexible display 2830 can be configured with... Figure 4 Flexible displays (e.g.) Figure 4 The configurations of the flexible display 400 are basically the same or similar.

[0308] Figure 29 This is a view showing a glass component according to an embodiment.

[0309] Figure 29 The glass component 2900 shown can be Figure 28A and Figure 28B Flexible displays (e.g.) Figure 28A Components of the flexible display 2830.

[0310] Reference Figure 29 The glass member 2900 can be configured such that at least a portion thereof is deformable. For example, the glass member 2900 may include a non-flexible region 2900a and a flexible region 2900b. Here, the non-flexible region 2900a of the glass member 2900 may correspond to... Figure 28B Non-flexible regions (e.g., Figure 28B The non-flexible region 2830a). Here, the flexible region 2900b of the glass member 2900 can correspond to Figure 28B The flexible region 2830b.

[0311] According to an embodiment, the glass component 2900 may include a first side surface 2901, a second side surface 2902 extending vertically from the first side surface 2901, a third side surface 2903 extending vertically from the second side surface 2902 and parallel to the first side surface 2901, and a fourth side surface 2904 extending vertically from the third side surface 2903 and parallel to the second side surface 2902.

[0312] According to an embodiment, the glass component 2900 may include a first glass portion 2910 and a second glass portion 2920.

[0313] According to an embodiment, the first glass portion 2910 may include a portion adjacent to the edge of the glass member 2900. The first glass portion 2910 may include a region within a predetermined distance from the edge of the glass member 2900. For example, the first glass portion 2910 may include a region within the flexible region 2900b within a predetermined distance from the edge of the glass member 2900 included in the flexible region 2900b. For example, the first glass portion 2910 may include a region within a predetermined interval from the edge portion of the glass member 2900 corresponding to the edge portion of the flexible region 2900b. For example, the first glass portion 2910 may include a region within a predetermined interval from a portion of a side surface of the glass member 2900 (e.g., a second side surface 2902 or a fourth side surface 2904). Here, the predetermined interval may be 1 mm or less, but this disclosure is not limited thereto.

[0314] According to an embodiment, the first glass portion 2910 may have a vertically symmetrical structure. However, it is not limited to this and may have a shape that further protrudes from at least one of the upper or lower sides. According to an embodiment, the first glass portion 2910 may have a shape that protrudes from at least one of the upper or lower sides. For example, one of the upper or lower sides may have a non-protruding shape.

[0315] The second glass portion 2920 may be a portion different from the first glass portion 2910. The second glass portion 2920 may include at least a portion of the glass member 2900 other than the first glass portion 2910.

[0316] According to an embodiment, the thickness of the first glass portion 2910 can be made relatively thicker than the thickness of the second glass portion 2920. For example, the thickness of the first glass portion 2910 can be greater than the average thickness of the glass member 2900. The rigidity of the first glass portion 2910 can be relatively stronger than the rigidity of the second glass portion 2920. The thickness difference between the first glass portion 2910 and the second glass portion 2920 can be formed by an etching process using chemicals, but the manufacturing method is not limited to this.

[0317] According to an embodiment, the first glass portion 2910 can be positioned therewith. Figure 5 The protective cap shown (e.g., Figure 5 Protective cap 510) and protective components (e.g., Figure 5 The overlapping location of at least a portion of the area in contact with the protective member 410. By forming a first glass portion 2910 that is relatively thicker than the second glass portion 2920, even if a foreign object is stuck... Figure 5 The first position (e.g., Figure 5 In the case of the first position D1), damage caused by foreign objects can also be effectively prevented or reduced.

[0318] According to an embodiment, the glass member 2900 may include a plurality of recesses 2940. The plurality of recesses 2940 may be formed to be recessed inward from an edge or side surface of the glass member 2900. For example, the plurality of recesses 2940 may be formed inward from the outside (or from its edge) of at least one side surface of the glass member 2900. The plurality of recesses 2940 may be formed near an edge corresponding to a flexible region 2900b of the glass member 2900. For example, the plurality of recesses 2940 may be formed to be recessed inward from an edge or side surface corresponding to a flexible region 2900b. The plurality of recesses 2940 may be formed by physical processing methods, laser processing methods, or chemical etching methods, but this disclosure is not limited thereto.

[0319] According to an embodiment, a plurality of recesses 2940 may be formed around the first glass portion 2910. For example, the first glass portion 2910 may have a comb-like shape due to the plurality of recesses 2940, but this disclosure is not limited thereto.

[0320] According to an embodiment, the plurality of recesses 2940 can be arranged to be spaced apart at predetermined intervals. For example, the plurality of recesses 2940 can be arranged to be spaced apart at predetermined intervals along the length direction of the glass member 2900. Here, the length direction of the glass member 2900 can refer to the length direction of the second side surface 2902. Here, the predetermined interval can be within 1 micrometer to 1 millimeter, but this disclosure is not limited thereto. For example, the depth of the plurality of recesses 2940 can be within 1 micrometer to 1 millimeter, but this disclosure is not limited thereto. For example, the width of the plurality of recesses 2940 can be within 1 micrometer to 1 millimeter, but this disclosure is not limited thereto.

[0321] Because each of the multiple recesses 2940 is formed with a small size of less than 1 mm, direct impact of the multiple recesses 2940 on the display panel can be prevented or reduced. For example, even when force is applied to a flexible display (e.g., Figure 28A In the case of the first glass portion 2910 side of the flexible display (2830), the force will not be directly applied to the display panel located below the first glass portion 2910, and the first glass portion 2910, which has a generally comb-shaped shape, can protect the display panel.

[0322] According to an embodiment, even within the flexible region 2900b, the spacing between the plurality of recesses 2940 can vary.

[0323] According to an embodiment, when the first glass portion 2910 of the glass member 2900 has a generally comb-like shape due to the plurality of recesses 2940, damage to the glass member 2900 due to the intrusion of foreign objects can be prevented or reduced. For example, even if a foreign object enters... Figure 5 The second position (e.g., Figure 5In the case of the second position D2), by reducing the side surface area of ​​the first glass portion 2910, the possibility of foreign objects contacting the side surface of the glass component 2900 can also be reduced.

[0324] Even if a foreign object comes into contact with the first glass portion 2910 of the glass member 2900 and a crack appears on the side surface of the first glass portion 2910, the generally comb-shaped structural features can prevent or reduce the propagation of the crack to the entire area of ​​the glass member 2900. Even if the flexible region 2900b of the glass member 2900 is bent, the stress applied to the first glass portion 2910 can be relatively reduced by having a generally comb-shaped first glass portion 2910. In other words, since the stress applied to the first glass portion 2910 with multiple recesses 2940 during bending is relatively small compared to glass without multiple recesses 2940, crack propagation can be prevented or reduced.

[0325] According to an embodiment, the glass component 2900 may include a third glass portion 2930. The third glass portion 2930 may be positioned between the first glass portion 2910 and the second glass portion 2920. The third glass portion 2930 may be the portion connecting the first glass portion 2910 and the second glass portion 2920.

[0326] According to an embodiment, the third glass portion 2930 may be formed to slope from the second glass portion 2920 toward the first glass portion 2910. The third glass portion 2930 may also be formed to slope downwards from the first glass portion 2910 toward the second glass portion 2920. However, not limited thereto, unlike what is shown, the third glass portion 2930 may form a step based on the thickness difference between the first glass portion 2910 and the second glass portion 2920.

[0327] According to an embodiment, the glass component 2900 may include first glass portions 1910, 2010, 2110, 2210 or multiple recesses 2030, 2230 of various shapes, as shown in the reference. Figures 19A to 22 As stated above.

For example, the width of the plurality of recesses 3140 can be within 1 micrometer to 1 millimeter, but the present disclosure is not limited thereto.

[0351] Because each of the plurality of recesses 3140 is formed with a small size of less than 1 mm, direct impact on the display panel by the plurality of recesses 3140 can be prevented or reduced. For example, even when force is applied to a flexible display (e.g., Figure 12 In the case of the first glass portion 3110 side of the flexible display 1200, the force will not be directly applied to the display panel located below the first glass portion 3110, and the first glass portion 3110, which has a generally comb-shaped shape, can protect the display panel.

[0352] According to an embodiment, the plurality of recesses 3140 may include a first plurality of recesses 3141 and a second plurality of recesses 3142. The first plurality of recesses 3141 may be disposed around a first folding axis F1. The second plurality of recesses 3142 may be disposed around a second folding axis F2.

[0353] According to an embodiment, the spacing between the first plurality of recesses 3141 and the spacing between the second plurality of recesses 3142 may be different. For example, the spacing between the first plurality of recesses 3141 may be narrower than the spacing between the second plurality of recesses 3142. However, this disclosure is not limited thereto.

[0354] According to an embodiment, the shape of the first plurality of recesses 3141 may be different from the shape of the second plurality of recesses 3142.

[0355] According to an embodiment, when the first glass portion 3110 of the glass member 3100 has a generally comb-like shape due to the plurality of recesses 3140, damage to the glass member 3100 due to the intrusion of foreign objects can be prevented or reduced. For example, even if a foreign object enters... Figure 5 The second position (e.g., Figure 5 In the case of the second position D2), by reducing the side surface area of ​​the first glass portion 3110, the possibility of foreign objects contacting the side surface of the glass component 3100 can also be reduced.

[0356] Even if a foreign object comes into contact with the first glass portion 3110 of the glass member 3100 and a crack appears on the side surface of the first glass portion 3110, the generally comb-shaped structural features can prevent or reduce the propagation of the crack to the entire area of ​​the glass member 3100. Even if the first folding axis F1 or the second folding axis F2 of the glass member 3100 is bent, the stress applied to the first glass portion 3110 can be relatively reduced by having a generally comb-shaped first glass portion 3110. In other words, since the stress applied to the first glass portion 3110 with multiple recesses 3140 during bending is relatively small compared with glass without multiple recesses 3140, crack propagation can be prevented or reduced.

[0357] According to an embodiment, the glass component 3100 may include a third glass portion 3130. The third glass portion 3130 may be positioned between the first glass portion 3110 and the second glass portion 3120.

[0358] According to an embodiment, the third glass portion 3130 may be formed to slope from the second glass portion 3120 toward the first glass portion 3110. The third glass portion 3130 may also be formed to slope downwards from the first glass portion 3110 toward the second glass portion 3120. However, not limited thereto, unlike what is shown, the third glass portion 3130 may form a step based on the thickness difference between the first glass portion 3110 and the second glass portion 3120.

[0359] According to an embodiment, the third glass portion 3130 may include a third-first glass portion 3131 and a third-second glass portion 3132. The third-first glass portion 3131 may be disposed around a first folding axis F1. The third-second glass portion 3132 may be disposed around a second folding axis F2.

[0368] Reference Figure 33B The glass component 3200-1 may include a recessed portion 3220. The recessed portion 3220 may be formed in the flexible region 3200b. By forming the recessed portion 3220 in the flexible region 3200b, the thickness of the glass component 3200-1 in the flexible region 3200b can be reduced. As a result, the repulsive force can be reduced and the bending performance can be enhanced.

[0369] Reference Figure 33C The glass member 3200-2 may include a first groove portion 3230 and a second groove portion 3240. The first groove portion 3230 and the second groove portion 3240 may each be arranged in a flexible region of the glass member 3200-2. The first groove portion 3230 may be formed on, for example, the upper surface of the glass member 3200-2 (e.g., the surface facing the +Z1 direction). The second groove portion 3240 may be formed on, for example, the lower surface of the glass member 3200-2 (e.g., the surface facing the -Z1 direction). The first groove portion 3230 and the second groove portion 3240 may be formed to overlap perpendicularly to each other. By forming the first groove portion 3230 and the second groove portion 3240, the bending performance of the glass member 3200-2 in the flexible region 3200b can be enhanced.
