Description

Technical Field

[0001] Various embodiments of the present disclosure relate to a rollable electronic device.

Background Art

[0002] Electronic devices are becoming thinner, increasing rigidity, enhancing design aspects, and improving their functional elements. Electronic devices are deviating from the uniform rectangular shape and are gradually transforming into various shapes. Electronic devices can have a deformable structure that is convenient to carry and can use a large-screen display. For example, as an example of a deformable structure, an electronic device can have a structure (e.g., a rollable structure or a slidable structure) that can vary the display area of a flexible display through the support of a housing that operates in a sliding manner with respect to each other. A rollable electronic device (or a slidable electronic device) can be configured such that a flexible display can be wound or unfolded. A slidable electronic device can be configured such that a flexible display moves in a sliding manner and the screen expands and contracts.

Summary of the Invention

Problems to be Solved by the Invention

[0003] When a bendable section of a display moves in a first direction (e.g., the x-axis direction) through a bent portion of an electronic device, a compressive force is applied, and the distance between the multi-bars of a bending member becomes narrower. When the distance between the multi-bars becomes narrower, interference between the multi-bars can occur, and local compressive forces and tensile stresses can be generated in the section between the multi-bars. Due to such compressive and tensile stresses, the display can lift and deformation can occur. Various embodiments of the present disclosure can provide a bending plate that can reduce the tensile stress caused by the narrowing of the distance between multi-bars at the bent portion of an electronic device and an electronic device including the same. [Means for solving the problem]

[0004] Electronic devices according to various embodiments of the present disclosure may include a first housing, a second housing, a flexible display, a bendable member, and a bending plate. The second housing may be slid in a first direction to be pulled out of the first housing by at least a portion thereof, and may be slid in a second direction to be pulled in of the first housing by at least a portion thereof. The flexible display may be arranged in the space formed by the first and second housings and may include a first region that is visually visible to the outside and a second region that extends from the first region, is housed inside when closed, and is visually visible to the outside when open. The bendable member may be arranged on the back of the flexible display to support the flexible display in the closed and open states and may include a plurality of multibars arranged at regular intervals. The bending plate may be attached to the flexible display and the plurality of multibars.

[0005] Display assemblies according to various embodiments of the present disclosure may include a flexible display, a bendable member, and a bending plate in a display assembly for an electronic device. The flexible display may include a first region that is visible from the outside and a second region that extends from the first region, is housed inside in a closed state, and is visible from the outside in an open state. The bendable member may include a plurality of multibars positioned behind the flexible display to support the flexible display in the closed and open states and arranged at regular intervals. The bending plate may be attached to the bottom of the flexible display and to the plurality of multibars.

Those skilled in the art will understand that the principles of the disclosure may be embodied in any appropriately configured system or apparatus.

[0015] Figure 1 is a block diagram of an electronic device 101 in a network environment 100 according to various embodiments of the present disclosure. Referring to Figure 1, in the network environment 100, the electronic device 101 can communicate with an electronic device 102 via a first network 198 (e.g., a short-range wireless communication network) or with at least one of an electronic device 104 or a server 108 via a second network 199 (e.g., a long-range wireless communication network). According to one embodiment, the electronic device 101 can communicate with an electronic device 104 via a server 108. According to one embodiment, the electronic device 101 may include a processor 120, memory 130, input module 150, acoustic output module 155, display module 160, audio module 170, sensor module 176, interface 177, coupling terminal 178, haptic module 179, camera module 180, power management module 188, battery 189, communication module 190, subscriber identification module 196, or antenna module 197. In some embodiments, the electronic device 101 may omit at least one of these components (e.g., the coupling terminal 178) or may have one or more other components added. In some embodiments, some of these components (e.g., the sensor module 176, the camera module 180, or the antenna module 197) may be integrated into a single component (e.g., the display module 160).

[0016] The processor 120 can, for example, control at least one other component (e.g., hardware or software component) of the electronic device 101 connected to the processor 120 by performing software (e.g., program 140), and can perform a variety of data processing or calculations.

According to one embodiment, the processor 120 may include a main processor 121 (e.g., central processing unit or application processor) or an auxiliary processor 123 (e.g., graphics processing unit, neural processing unit (NPU), image signal processor, sensor processor, or communication processor) that can be operated independently or together with it. For example, if the electronic device 101 includes a main processor 121 and an auxiliary processor 123, the auxiliary processor 123 may use less power than the main processor 121 or be configured to specialize in a specified function. The auxiliary processor 123 can be implemented separately from the main processor 121, or as part of it.

According to one embodiment, the receiver can be embodied separately from or as part of the speaker.

[0022] The display module 160 can visually provide information to an external party (e.g., a user) outside of the electronic device 101. The display module 160 may include, for example, a display, a hologram device, or a projector and a control circuit for controlling said device. According to one embodiment, the display module 160 may include a touch sensor configured to detect touches, or a pressure sensor configured to measure the intensity of the force generated by said touches.

[0023] The audio module 170 can convert sound into electrical signals, or conversely, convert electrical signals into sound. In one embodiment, the audio module 170 can acquire sound via the input module 150, or output sound via the acoustic output module 155, or via an external electronic device (e.g., electronic device 102) (e.g., speaker or headphones) directly or wirelessly connected to the electronic device 101.

[0024] The sensor module 176 can detect the operating state of the electronic device 101 (e.g., power or temperature) or the external environmental state (e.g., user state) and generate an electrical signal or data value corresponding to the detected state. According to one embodiment, the sensor module 176 may include, for example, a gesture sensor, a gyroscope, a barometric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an IR (infrared) sensor, a biosensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

[0025] Interface 177 can support one or more designated protocols that can be used for the electronic device 101 to connect directly or wirelessly to an external electronic device (e.g., electronic device 102). According to one embodiment, interface 177 may include, for example, HDMI (High Definition Multimedia Interface) (registered trademark), USB (Universal Serial Bus) interface, SD card interface, or audio interface.

[0026] The connecting terminal 178 may include a connector through which the electronic device 101 can be physically connected to an external electronic device (e.g., electronic device 102). According to one embodiment, the connecting terminal 178 may include, for example, an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).

[0029] The power management module 188 can manage the power supplied to the electronic device 101. According to one embodiment, the power management module 188 can be embodied, for example, as at least part of a PMIC (power management integrated circuit).

[0030] The battery 189 can supply power to at least one component of the electronic device 101. According to one embodiment, the battery 189 may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0031] The communication module 190 can support the establishment of a direct (e.g., wired) or wireless communication channel between the electronic device 101 and an external electronic device (e.g., electronic device 102, electronic device 104, or server 108), and the execution of communication through the established communication channel. The communication module 190 operates independently of the processor 120 (e.g., an application processor) and may include one or more communication processors that support direct (e.g., wired) or wireless communication. According to one embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a near-field wireless communication module, or a GNSS (global navigation satellite system) communication module) or a wired communication module 194 (e.g., a LAN (local area network) communication module, or a power line communication module). The relevant communication module among these communication modules can communicate with an external electronic device 104 via a first network 198 (e.g., a short-range communication network such as Bluetooth®, WiFi (wireless fidelity) direct, or IrDA (infrared data association)) or a second network 199 (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or WAN)). Many types of such communication modules can be integrated into a single component (e.g., a single chip) or embodied in multiple separate components (e.g., multiple chips). The wireless communication module 192 can verify or authenticate the electronic device 101 within a communication network such as the first network 198 or the second network 199 using subscriber information (e.g., an International Mobile Subscriber Identifier (IMSI)) stored in the subscriber identification module 196.

[0032] The wireless communication module 192 can support 5G networks and next-generation communication technologies beyond 4G networks, such as NR connection technology (new radio access technology). NR connection technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimizing terminal power and connecting a large number of terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). For example, the wireless communication module 192 can support high-frequency bands (e.g., mmWave bands) to achieve high data transmission rates. The wireless communication module 192 supports various technologies to ensure performance in high-frequency bands, such as beamforming, massive array multiplexing (massive MIMO (multiple-input and multiple-output)), full-dimensional multiplexing (FD-MIMO) (full-dimensional MIMO), array antennas, analog beamforming, or large-scale antennas. It can support technologies such as antennas. The wireless communication module 192 can support a variety of requirements specified by the electronic device 101, external electronic devices (e.g., electronic device 104), or network system (e.g., second network 199). According to one embodiment, the wireless communication module 192 can support a peak data rate for eMBB realization (e.g., 20 Gbps or more), loss coverage for mMTC realization (e.g., 164 dB or less), or U-plane latency for URLLC realization (e.g., 0.5 ms or less for both downlink (DL) and uplink (UL), or 1 ms or less for round trip).

[0033] The antenna module 197 can transmit or receive signals or power to or from an external source (e.g., an external electronic device). In one embodiment, the antenna module 197 may include an antenna comprising a radiator consisting of a conductor or conductive pattern formed on a substrate (e.g., a PCB). In one embodiment, the antenna module 197 may include a plurality of antennas (e.g., an array antenna). In such a 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 plurality of antennas, for example, by a communication module 190. Signals or power can be transmitted or received between the communication module 190 and an external electronic device via the selected at least one antenna. In one embodiment, other components (e.g., an RFIC (radio frequency integrated circuit)) may be added in addition to the radiator to form part of the antenna module 197.

[0034] According to one embodiment, the antenna module 197 can form an mmWave antenna module. According to one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent to a first surface (e.g., the bottom surface) of the printed circuit board and capable of supporting a specified high-frequency band (e.g., the mmWave band), and a plurality of antennas (e.g., array antennas) disposed on or adjacent to a second surface (e.g., the top or side surface) of the printed circuit board and capable of transmitting or receiving signals in the specified high-frequency band.

[0035] At least some of the aforementioned components are connected to each other via a communication method between peripheral devices (e.g., bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)) and can exchange signals (e.g., instructions or data) with each other.

[0036] In one embodiment, commands or data can be transmitted to or received between the electronic device 101 and an external electronic device 104 via a server 108 connected to a second network 199. Each of the external electronic devices 102 or 104 may be the same type of device as the electronic device 101 or a different type of device. In one embodiment, all or part of the operation performed by the electronic device 101 can be performed by one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 must perform a certain function or service automatically or in response to a request from a user or another device, the electronic device 101 may, instead of performing the function or service itself, or additionally, request one or more external electronic devices to perform at least part of that function or service. One or more external electronic devices that receive the request may perform at least part of the requested function or service, or additional functions or services related to the request, and transmit the result of the execution to the electronic device 101. The electronic device 101 can process the results as they are or additionally and provide them as at least part of the response to the request. For this purpose, for example, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology can be used. The electronic device 101 can provide ultra-low latency services using, for example, distributed computing or mobile edge computing. In other embodiments, the external electronic device 104 may include IoT (Internet of Things) devices. The server 108 may be an intelligent server using machine learning and / or neural networks. According to one embodiment, the external electronic device 104 or the server 108 may be included within the second network 199. The electronic device 101 can be applied to intelligent services (e.g., smart homes, smart cities, smart cars, or healthcare) based on 5G communication technology and IoT-related technologies.

In such cases, the integrated component may perform one or more functions of each of the multiple components in the same or similar manner as they were performed by those components in the multiple components prior to the integration. According to various embodiments, operations performed by a module, program or other component may be performed sequentially, in parallel, repeatedly, or heuristically, or one or more of the operations may be performed in other steps, omitted, or one or more other operations may be added.

[0043] According to one embodiment, the display module 160 shown in Figure 1 may include a flexible display configured to be folded or unfolded.

[0044] According to one embodiment, the display module 160 shown in Figure 1 may include a flexible display that is slidably positioned to provide a screen (e.g., a display screen).

[0045] For example, the display area of ​​the electronic device 101 is an area that is visually exposed and capable of outputting an image, and the electronic device 101 can adjust the width of the display area by moving the housing or the display. An example of such a display module 160 is a rollable electronic device configured to selectively expand the display area by having at least a part of the electronic device 101 (e.g., the housing) operate in a sliding manner at least partially. For example, the display module 160 may also be referred to as a slide-out display or an expandable display.

[0046] Figure 2 is a drawing showing the front (e.g., first surface) and rear (e.g., second surface) of a rollable electronic device in a first state (e.g., closed state) according to various embodiments of the present disclosure.

[0047] According to various embodiments, the electronic device 300 in Figure 2 may include the electronic device 101 in Figure 1.

[0048] Referring to Figure 2, an electronic device 300 (e.g., a rollable electronic device) according to various embodiments of the present disclosure may include a first plate 201 facing a first direction (e.g., the front) and a second plate 203 facing a second direction (e.g., the rear) opposite to the first direction (e.g., the front). The electronic device 300 may include a display 310 (e.g., display 310 in Figures 3 and 4, display 610 in Figure 6) that is visually exposed through a housing 320 (e.g., a first housing 360, a second housing 370, and the first plate 201 in Figures 3 and 4) that forms a space between the first plate 201 and the second plate 203. Here, the display 310 may be an OLED display or an LCD display. According to one embodiment, the first plate 201 may be formed to be substantially transparent in part. For example, the first plate 201 may be formed from a glass plate or a polymer plate including various coating layers.

[0049] The electronic device 300 may include a front surface 301 (e.g., a first surface) facing a first direction (e.g., the z-axis direction), a rear surface 302 (e.g., a second surface) facing a second direction opposite to the first direction (e.g., the -z-axis direction), a side surface 303 formed between the front surface 301 and the rear surface 302, and a predetermined space provided between the front surface 301 and the rear surface 302. The side surface 303 may include a first side surface 303a positioned in the x-axis direction, a second side surface 303b positioned in the -x-axis direction, a third side surface 303c positioned in the y-axis direction, and a fourth side surface 303d positioned in the -y-axis direction.

[0050] In one embodiment, the electronic device 300 can slide in at least one direction from the x-axis direction, -x-axis direction, y-axis direction, and / or -y-axis direction to expand or shrink the screen of the display 310. In this disclosure, one example can be described of the display 310 screen being expanded by sliding the electronic device 300 in the x-axis direction while it is in a reduced state. Another example can be described of the display 310 screen being reduced by sliding the electronic device 300 in the -x-axis direction while it is in an expanded state. However, the invention is not limited thereto, and the display 310 screen can also be expanded and reduced in the x-axis direction and the -x-axis direction (for example, both directions with respect to the x-axis). On the other hand, the display 310 screen can also be expanded and reduced in the y-axis direction and the -y-axis direction (for example, both directions with respect to the y-axis).

[0051] In one embodiment, the housing 320 can be formed of a metallic material so as to surround the space between the front 301 and rear 302 of the electronic device 300. In one embodiment, at least a portion of the housing 320 can also be formed of a non-metallic material. The display 310 can be visually exposed to the outside from the front 301 of the electronic device 300. A back cover 330 (e.g., back cover 690 in Figure 6) (e.g., rear cover) can be visually exposed to the outside from the rear 302 of the electronic device 300. The back cover 330 can be formed of a polymer, coated or colored glass, ceramics, metal (e.g., aluminum, stainless steel (STS), or magnesium), or a combination of at least two of the above materials.

[0052] In one embodiment, the electronic device 300 may include a connector hole 322 and an audio hole 324. In one embodiment, the connector hole 322 may house a first connector for transmitting and receiving power and / or data with an external electronic device, and / or a second connector for transmitting and receiving audio signals with an external electronic device. For example, the connector hole 322 may include a USB connector or an earphone jack. In one embodiment, the USB connector and the earphone jack may be embodied in a single hole. In one embodiment, the electronic device 300 may also transmit and receive power and / or data or audio signals wirelessly with an external electronic device without a separate connector hole. In one embodiment, the audio hole 324 may include a microphone hole and / or a speaker hole. In one embodiment, the electronic device 300 may include an audio module (e.g., the audio module 170 in Figure 1). The audio module may include a microphone for acquiring external sound and a speaker for outputting sound externally. At least a microphone and at least one speaker may be located inside the audio hole 324. In one embodiment, the speaker hole and microphone hole may be embodied in a single audio hole 324, or a speaker (e.g., a piezo speaker) may be included without a speaker hole. The speaker hole may include an external speaker hole and a receiver hole for communication.

[0053] In one embodiment, the electronic device 300 may include at least one of the following: an input module (e.g., input module 150 in Figure 1), an acoustic output module (e.g., acoustic output module 155 in Figure 1), a sensor module 307 (e.g., sensor module 176 in Figure 1), a camera module 305 (e.g., camera module 180 in Figure 1), and a connector port (e.g., connecting terminal 178 in Figure 1). For example, the camera module 305 (e.g., camera module 180 in Figure 1) and the sensor module 307 (e.g., sensor module 176 in Figure 1) may be located below the display 310. In other embodiments, the electronic device 300 may be configured to omit at least one of the above-described components or to include additional components.

[0054] In one embodiment, the sensor module 307 (for example, the sensor module 176 in Figure 1) can generate electrical signals or data values ​​corresponding to the internal operating state of the electronic device 300 or the external environmental state.

[0055] In one embodiment, the sensor module 307 (for example, the sensor module 176 in Figure 1) may include a first sensor module (for example, a proximity sensor or an illuminance sensor) located on the front 301 of the electronic device 300 and / or a second sensor module (for example, an HRM (heart rate monitoring) sensor) located on the rear 302.

[0056] In one embodiment, the first sensor module can be positioned on the front surface 301 of the electronic device 300, below (for example, at the bottom) of the display 310. According to one embodiment, the first sensor module may include at least one of the following: a proximity sensor, an illuminance sensor, a TOF (time of flight) sensor, an ultrasonic sensor, a fingerprint recognition sensor, a gesture sensor, a gyroscope sensor, a barometric pressure sensor, a magnetic sensor, an accelerometer, a grip sensor, a color sensor, an IR (infrared) sensor, a biosensor, a temperature sensor, or a humidity sensor.

[0057] According to one embodiment, the electronic device 300 may also include at least one antenna (e.g., the antenna module 197 in Figure 1). According to one embodiment, the at least one antenna (e.g., the antenna module 197 in Figure 1) may be configured to transmit and receive signals for wireless communication with, for example, an external electronic device (e.g., the electronic device 104 in Figure 1). According to one embodiment, the electronic device 300 may also include other antennas located in the internal space. According to one embodiment, the other antennas may wirelessly transmit and receive power necessary for charging. According to one embodiment, the at least one antenna and / or the other antennas may include a legacy antenna, a mmWave antenna, an NFC (near-field communication) antenna, a wireless charging antenna, and / or an MST (magnetic secure transmission) antenna.

[0058] In one embodiment, the first state of the electronic device 300 (for example, the closed state) can be represented as a screen-reduced state, a slide-in state, or a slide-closed state. In another embodiment, the second state of the electronic device 300 (for example, the open state) can be represented as a screen-expanded state, a slide-out state, or a slide-open state.

[0059] In one embodiment, when the display 310 is moved by an external force, the electronic device 300 can be switched from a closed state to an open state, or from an open state to a closed state (for example, by a semi-automatic sliding operation), without any further external force.

[0060] In other embodiments, when a signal is generated via an input device included in the electronic device 300, a drive device such as a motor or hinge connected to the display 310 can cause the electronic device 300 to switch from a closed state to an open state, or from an open state to a closed state. For example, when a signal is generated via a hardware button or a software button provided via the screen, the electronic device 300 can switch from a closed state to an open state, or from an open state to a closed state.

[0061] In other embodiments, when signals are generated from various sensors, such as pressure sensors, the electronic device 300 can be switched from a closed state to an open state, or from an open state to a closed state. For example, a squeeze gesture in which a part of the hand (e.g., palm or fingers) pressurizes a designated section of the electronic device 300 when it is carried or grasped can be detected via a sensor, and the device can be switched in response from a closed state to an open state, or from an open state to a closed state.

[0062] Figure 3 is a drawing showing the front (e.g., first surface) (e.g., the surface on which a screen is displayed) of an electronic device in a first state (e.g., closed state) according to various embodiments of the present disclosure. Figure 4 is a drawing showing the front (e.g., first surface) (e.g., the surface on which a screen is displayed) of an electronic device in a second state (e.g., open state) according to various embodiments of the present disclosure. Figure 5 is a drawing showing the rear (e.g., second surface) of an electronic device in a second state (e.g., open state) according to various embodiments of the present disclosure.

[0063] The electronic devices 300 in Figures 3 to 5 are at least partially similar to the electronic device 101 in Figure 1 or the electronic device 300 in Figure 2, or may further include other embodiments of the electronic device.

[0064] Referring to Figures 3 to 5, the display 310 of the electronic device 300 according to various embodiments of the present disclosure may include an extended region 312 and a fixed region 314. In the open state (e.g., second state) of the electronic device 300 according to various embodiments of the present disclosure, the fixed region 314 can be supported by one region of a bendable member (e.g., the bendable member 620 in Figures 6 and 7). Also, in the open state (e.g., second state) of the electronic device 300, the extended region 312 can be supported by another region of the bendable member (e.g., the bendable member 620 in Figures 6 and 7). This allows the fixed region 314 of the display 310 supported by the bendable member (e.g., the bendable member 620 in Figures 6 and 7) to form a plane. Furthermore, a portion of the extended area 312 of the display 310 can form a flat surface using a support plate (for example, the support plate 641 in Figure 6), while another portion can form a curved surface using a curved area of ​​the support plate (for example, the sliding bar 634 in Figure 6) (for example, the pressurizing portion).

[0065] As an example, in the closed state of the electronic device 300 (e.g., first state), at least a portion of the bendable member (e.g., the bendable member 620 in Figure 6) can be housed inside the second housing 370 (e.g., the second housing 660 in Figure 6). The bendable member (e.g., the bendable member 620 in Figure 6) can be retracted into the space between the support plate (e.g., the support plate 641 in Figure 6) and the second housing 370 (e.g., the second housing 660 in Figure 6) under the support of the sliding bar (e.g., the pressurizing section 643 in Figure 6) (e.g., the sliding bar) of the electronic device 300. In this case, at least a portion of the bendable member (e.g., the bendable member 620 in Figures 6 and 7) can be in contact with the drive body (e.g., the pressurizing link 645 in Figure 6) (e.g., the drive body).

[0066] In one embodiment, although not shown, a bendable member (e.g., the bendable member 620 in Figures 6 and 7) may have a portion of the plate (e.g., a support plate) that substantially corresponds to the fixed region 314. At least a portion of the display 310 (e.g., a bendable section) (e.g., an extended region 312) can be arranged so as not to be seen from the outside by being housed in the internal space of the second housing 370 (e.g., the second housing 660 in Figure 6) while being supported by the bendable member (e.g., the bendable member 620 in Figures 6 and 7) in a closed state (e.g., a first state).

[0067] According to one embodiment, at least a portion of the display 310 (e.g., a bendable section) (e.g., an extended region 312) can be positioned in an open state (e.g., a second state) and be visible from the outside while being supported by the bendable member 620.

[0068] According to one embodiment, the electronic device 300 may include a front surface 301 on which the screen of the display 310 is displayed, a rear surface 302 facing in the opposite direction from the front surface 301, and a side surface 303 surrounding the space between the front surface 301 and the rear surface 302.

[0069] According to one embodiment, the area of ​​the front 301 and rear 302 of the electronic device 300 can be varied depending on the state of the electronic device 300 (e.g., open or closed). For example, when the electronic device 300 is in an open state (e.g., the open state in Figure 4), the area of ​​the front 301 of the electronic device 300 (e.g., the screen area) can be increased by extending the bendable section (e.g., the extended area 312) of the display 310. For example, when the electronic device 300 is in a closed state (e.g., the closed state in Figure 3), the area of ​​the rear 302 of the electronic device 300 may include the area of ​​the back cover (e.g., the back cover 330 in Figure 2, the back cover 690 in Figure 6) (e.g., the rear cover). Furthermore, when the electronic device 300 is in an open state, the area of ​​the rear surface 302 of the electronic device 300 may include the area of ​​the back cover (e.g., the back cover 330 in Figure 2, the back cover 690 in Figure 6) (e.g., the rear cover) and substantially corresponding areas in the bendable region of the rear surface of the second housing 370 (e.g., the second housing 660 in Figure 6).

[0070] According to one embodiment, the display 310 may include a fixed area 314 that is always visually visible to the outside and an extended area 312 that is visually visible to the outside when it is in an open state (e.g., a second state). The extended area 312 is visually visible to the outside only when the electronic device 300 is in an open state (e.g., a second state), and the fixed area 314 is visually visible to the outside when it is in a closed state (e.g., a first state) and an open state (e.g., a second state). For example, the extended area 312 extends from the fixed area 314 and can be retracted inward or pulled outward in accordance with the movement of the second housing 370 (e.g., the second housing 660 in Figure 6).

[0071] According to one embodiment, the display 310 can be extended in an open state according to a first direction (e.g., the -x axis direction) while being supported by a bending member 620 (e.g., the bending member 620 in Figures 6 and 7). In such a case, at least a portion of the fixed region 314 and the extended region 312 can form substantially the same plane.

[0072] In one embodiment, the size (or area) of the display area of ​​the display 310 of the electronic device 300 can be varied by moving the second housing 370 (e.g., the second housing 660 in Figure 6) and the support plate (e.g., the support plate 641 in Figure 6) in a sliding manner in a first direction (e.g., the -x axis direction) or in a second direction (e.g., the x axis direction) opposite to the first direction (e.g., the -x axis direction).

[0073] According to one embodiment, the closed state (e.g., first state) (e.g., screen expansion, slide-out) and / or open state (e.g., second state) (e.g., screen reduction, slide-in) of the electronic device 300 can be passively performed through user operation.

[0074] According to one embodiment, the closed state (e.g., first state) (e.g., screen expansion, slide-out) and / or open state (e.g., second state) (e.g., screen reduction, slide-in) of the electronic device 300 can be performed automatically or semi-automatically using a drive device (e.g., motor, ball screw, cam, slider crank, or hinge).

[0075] Figure 6 is an exploded perspective view of an electronic device according to various embodiments of this disclosure.

[0076] Referring to Figure 6, an electronic device 600 according to various embodiments of the present disclosure (e.g., the electronic device 300 in Figures 3 and 4) may include a display 610 (e.g., the display 310 in Figure 2, the display 310 in Figures 3 and 4), a bendable member 620, a first housing 630, a support assembly 640, a guide rail 650, a second housing 660 (e.g., the second housing 370 in Figures 3 and 4), a printed circuit board 670, a battery 680, and a back cover (690) (e.g., a back glass) (e.g., a rear cover).

[0077] In various embodiments of the present disclosure, the electronic device 300 has an internal space provided by a first housing 630 and a second housing 660, in which a battery 680 (e.g., battery 189 in Figure 1) and a printed circuit board 670 can be arranged. At least some of the processor 120, memory 130, input module 150, acoustic output module 155, audio module 170, sensor module 176, interface 177, coupling terminal 178, haptic module 179, camera module 180, power management module 188, and communication module 190 shown in Figure 1, and / or other components of the electronic device 300 can be arranged.

[0078] In one embodiment, the display 610 is made of a flexible material, is capable of rolling, and can display images based on input video signals. The display 610 may include a first section 612 (e.g., fixed section 610a in Figure 10) that is visually exposed to the outside when the screen is retracted (e.g., closed), and a second section 614 (e.g., bendable section 610b in Figure 10) that is visually exposed to the outside when the screen is extended (e.g., open).

[0079] In one embodiment, the electronic device 600 can have a first space 661 formed by a first housing 630 and a second space 662 formed by a second housing 660. The second housing 660 can be slidably coupled to the first housing 630. A bendable member 620 can be positioned to be at least partially rotatable in the second space 662. A display 610 can be positioned to be supported by at least a portion of the bendable member 620 and the first housing 630.

[0080] According to one embodiment, the first space 661 of the first housing 630 can be provided through the coupling of the first bracket housing 630a and the second bracket housing 630b.

[0081] According to one embodiment, the electronic device 600 may include a printed circuit board 670 and a battery 680 arranged in the first space 661. The printed circuit board 670 and the battery 680 can be arranged in close proximity.

[0082] According to one embodiment, the electronic device 600 may include a camera module (e.g., camera module 305 in Figure 3) and a sensor module (e.g., sensor module 307 in Figure 3) located in the first space 661.

[0083] In one embodiment, the bendable member 620 can be arranged such that one end is fixed to the first housing 630 and the other end is at least partially movably housed in the second space 662 of the second housing 660. For example, in a retracted state, the bendable member 620 can be at least partially housed in the second space 662. In an extended state, the bendable member 620 can be at least partially extended from the second space 662 so as to form substantially the same plane as the first housing 630 (e.g., the second bracket housing 630b). Thus, the display 610, supported by at least a portion of the first housing 630 and the bendable member 620, can have its visible display area varied by sliding.

[0084] In one embodiment, the electronic device 600 is positioned between the first housing 630 and the second housing 660 and may include at least one guide rail 650 for guiding the sliding motion of the second housing 660. In one embodiment, the electronic device 600 may further include a cover member (not shown) positioned to cover both sides of the first housing 630 (e.g., the third side 303c in Figures 2 and 3) and the fourth side 303d.

[0085] According to various embodiments, the electronic device 600 may include a support assembly 640. The support assembly 640 is positioned to be at least partially movable from the first housing 630 in a first direction (e.g., the x-axis direction in Figures 2 and 3) and can be pressed in a direction that pulls out the second housing 660.

[0086] In one embodiment, the support assembly 640 may include a support plate 641 and at least one pressurizing link 645. In one embodiment, the support plate 641 may be slidably coupled to a first housing 630 (e.g., a second bracket housing 630b). In one embodiment, at least one pressurizing link 645 may be positioned to be supported by the first housing 630 (e.g., a second bracket housing 630b) and pressurize the support plate 641 in the pull-out direction (e.g., the x-axis direction in Figures 2 and 3).

[0087] In one embodiment, at least one pressurizing link 645 includes at least two unit links connected via an elastic member (e.g., a torsion spring), and can provide an extensor that pressurizes the support plate in the pull-out direction (e.g., in the -x axis direction) via the opening force of the unit links.

[0088] In one embodiment, the support plate 641 may include a plate portion 642 and a pressurizing portion 643 (e.g., a sliding bar). In one embodiment, the plate portion 642 may be slidably coupled to the first housing 630 and may include a first surface 6421 facing a specified direction (e.g., the z-axis direction) and a second surface 6422 facing the opposite direction to the first surface 6421 (e.g., the -z-axis direction). In one embodiment, the pressurizing portion 643 (e.g., a sliding bar) may be extended at the end of the plate portion 642 to have substantially the same length as the support plate 641 in the longitudinal direction (e.g., the y-axis direction in Figures 2 and 3).

[0089] In one embodiment, the pressurizing portion 643 can be formed in a shape that minimizes frictional force in order to pressurize the back surface of the bendable member 620. For example, the outer surface of the pressurizing portion 643 can be formed to have a curved surface. In one embodiment, the pressurizing portion 643 can also be structurally coupled to the plate portion 642 as a separate component. In one embodiment, the plate portion 642 can include a link guide 6423 formed to guide at least one pressurizing link 645. In one embodiment, at least one pressurizing link 645 can provide an applied pressure that always pressurizes the second housing 660 in the draw direction ((1) direction). During operation, at least one pressurizing link 645 can help reduce the sagging phenomenon of the display 610 by supporting the bendable member 620. In one embodiment, a support plate 641 can help form the second space 662 by being coupled to the second housing 660. In one embodiment, the support plate 641 can also be replaced by a part of the second housing 660.

[0090] According to various embodiments, the electronic device 600 may have an anti-lift structure for guiding the bendable member 620 to move in a manner that brings it into close contact with the first surface 6421 of the plate portion 642 of the support plate 641. According to one embodiment, the anti-lift structure may be positioned via at least a portion of the support assembly 640. According to one embodiment, the anti-lift structure may include at least one guide slit 6424 formed at specified intervals on the back surface of the bendable member 620.

[0091] According to one embodiment, at least one guide slit 6424 can also be formed to have a length along the retraction and withdrawal directions of the electronic device 600.

[0092] According to one embodiment, the bendable member 620 may include a plurality of multibars (for example, a plurality of multibars 622 in Figure 7) that are rotatably connected to one another.

[0093] According to various embodiments, at least a portion of the display 610 can be fixed to the bendable member 620 by taping, welding, or bonding. In one embodiment, the bendable member 620 to which at least a portion of the display 610 is attached can be positioned in substantially close contact with at least a portion of the first surface 6421 of the plate portion 642 of the support plate 641 and the outer surface of the pressurizing portion 643. In a retracted state, the bendable member 620 can be housed together with the display 610 in the second space 662 of the second housing 660 by the sliding motion of the support plate 641.

[0094] Figure 7 is a drawing showing a bendable member according to various embodiments of the present disclosure. Figure 8 is a drawing showing a display supported by a bendable member according to various embodiments of the present disclosure.

[0095] Referring to Figures 6 to 8, in one embodiment, the bendable member 620 may include a plurality of multi-bars 622 to perform the rolling motion of the display 610. The front surface 620a of the bendable member 620 may be in contact with the display 610, and the rear surface 620b may be in contact with the first housing 630.

[0096] In one embodiment, the front surface 615 of the display 610 can be oriented in the direction of the y-axis (e.g., the y-axis in Figures 2 and 3), and the back surface 616 of the display 610 can be oriented in the direction of the -y-axis (e.g., the -y-axis in Figures 2 and 3). In one embodiment, the bendable member 620 can be attached to the back surface 616 of the display 610 with an adhesive (e.g., a heat-activated adhesive, a photo-activated adhesive, a general adhesive, and / or double-sided tape). Multiple multi-bars 622 of the bendable member 620 can be arranged at regular intervals (gaps). The bendable member 620 can support the bendable section 610b of the display 610 (e.g., the bendable section 610b in Figure 10) so that the bendable section 610b of the display 610 is maintained in a form that is smoothly connected to the fixed section (1) of the display 610.

[0097] According to one embodiment, the multiple multibars 622 can be formed from a metal material and / or polymer. Each of the multiple multibars 622 may include guide projections 624 formed at both ends to guide along the guide rail 650 in the internal space of the electronic device 600.

[0098] According to one embodiment, some or all of the multiple multibars 622 may include at least one of the friction reduction regions (e.g., a POM layer, an acetal layer, or a teplon layer) to reduce friction. For example, the friction reduction region may be included in the region where contact (or friction) occurs between at least one of the multibars 622.

[0099] In one embodiment, although not shown, a bending plate (for example, the bending plate 1320 in Figure 13) can be placed on the bendable member 620. For example, the bending plate (for example, the bending plate 1320 in Figure 13) can be used to connect multiple bars to support a fixed section (for example, the fixed section 610a in Figure 10).

[0100] According to one embodiment, the support assembly 640 can slide in the -x-axis direction and the x-axis direction in accordance with the movement of the second housing 660 to expand or contract the screen of the display 610. For example, the support assembly 640 can expand the screen of the display 610 by pushing the bendable member 620 in the x-axis direction. Alternatively, when the second housing 660 moves in the -x-axis direction due to an external force, the support assembly 640 can contract the screen of the display 610 by pushing the bendable member 620 in the -x-axis direction. The support assembly 640 can support at least a portion of the bendable member 620 at the bend where the display 610 is bent (e.g., the bend 601 in Figure 10). Furthermore, when the screen of the display 610 is expanded, the support assembly 640 can support the bendable member 620 in a flat area other than the bend (e.g., the flat area 602 in Figure 10).

[0101] Figure 9 is a drawing showing guide rails according to various embodiments of the present disclosure.

[0102] Referring to Figures 6, 8, and 9, the guide rail 650 may include a side body 652 forming at least one side of the electronic device 600, and a guide groove 654 into which at least a portion of the display 610 and / or the bendable member 620 (e.g., a guide projection 624) is inserted to guide the movement of the bendable member 620. The guide rail 650 can provide a path for the display 610 and / or the bendable member 620 to move through the guide groove 654. For example, the guide rail 650 can be positioned inside the second housing 660 in the y-axis direction and the -y-axis direction, respectively. The guide rail 650 allows the display 610 to be retracted or pulled out in the second housing 660 by the bendable section of the display 610 (e.g., the bendable section 610b in Figure 10) being retracted or pulled out along the guide rail 650, thereby allowing the display 610 to smoothly connect with the side of the second housing 660.

[0103] In one embodiment, the first housing 630 can house at least a portion of the second housing 660, be coupled with the second housing 660, protect the electronic components located inside the electronic device 600, and form the appearance of the electronic device 600.

[0104] According to one embodiment, the second housing 660 can be slid in a first direction (e.g., the x-axis direction in Figures 2 and 3) when moving the display 610 to expand its screen. According to one embodiment, the second housing 660 can be slid in a second direction (e.g., the -x-axis direction in Figures 2 and 3) when moving the display 610 to reduce its screen size.

[0105] According to one embodiment, a back cover 690 (e.g., back glass) is located at the bottom of the first housing 630 and can become the apparent case of the electronic device 600. The back cover 690 can be formed from a polymer, coated or colored glass, ceramics, metal (e.g., aluminum, stainless steel (STS), or magnesium), or a combination of at least two of the above materials.

[0106] Figure 10 is a drawing showing fixed and bendable sections of a display according to various embodiments of the present disclosure. Figures 11 and 12 are drawings showing that a display is supported by a bendable member according to various embodiments of the present disclosure.

[0107] Referring to Figures 10 to 12, the movement of the bendable member 620 is guided by the guide rail 650, allowing the bendable member 620 to move in the x-axis direction and the -x-axis direction. The display 610 attached to the bendable member 620 can be expanded or contracted by the movement of the bendable member 620.

[0108] In various embodiments of the present disclosure, in a first state (e.g., closed state), only the fixed section 610a of the display 610 can be visually exposed to the outside. In a second state (e.g., open state) of the electronic device 600, the bendable section 610b of the display 610 moves in the x-axis direction via the bend 601, thereby allowing both the fixed section 610a and the bendable section 610b to be visually exposed to the outside. Multiple multibars of the bendable member 620 (e.g., multibar 622 in Figure 8) support the display 610 in at least a portion of the bendable section 610b and the fixed section 610a, thereby reducing the display 610 from floating up or sagging in the z-axis direction.

[0109] Figure 13 is a drawing showing a bending plate 1320 positioned between a display 610 and a multi-bar 1310 of a bendable member in various embodiments of the present disclosure. Figure 14 is a drawing showing a bending plate in various embodiments of the present disclosure.

[0110] Referring to Figures 13 and 14, the bending plate 1320 can be positioned between the display 610 and the multi-bar 1310 of the bendable member.

[0111] According to one embodiment, the bending plate 1320 can be placed in a bendable section (for example, the bendable section 610b in Figure 10) located in the lower part of the display 610 so as to be visible from the outside when in a slide-out state.

[0112] In one embodiment, the upper surface of the bending plate 1320 can be attached to the lower surface of the display 610 via a first adhesive member 1330 (e.g., a first adhesive tape). For example, the first adhesive member 1330 can be attached to the entire upper surface of the bending plate 1320. The lower surface of the bending plate 1320 can be attached to the upper surface of the multibar 1310 (e.g., the upper surface 1311 in Figure 15a) via a separate second adhesive member (e.g., a second adhesive tape). For example, the second adhesive member 1340 can be attached to the entire lower surface of the bending plate 1320.

[0113] According to one embodiment, the lower surface of the bending plate 1320 can be attached to the upper surface of the multibar 1310 (for example, the upper surface 1311 in Figure 15a) via welding. According to one embodiment, the lower surface of the bending plate 1320 can be attached to the upper surface of the multibar 1310 (for example, the upper surface 1311 in Figure 15a) via bonding.

[0114] According to one embodiment, the bending plate 1320 can be made of a metal material or rubber (for example, urethane, LSR (liquid silicone rubbers)). However, it is not limited thereto, and the bending plate 1320 can be made of a material that is flexible to compressive and tensile stresses and has little change in thickness when compressed and tensile stresses are applied.

[0115] According to one embodiment, the bending plate 1320 may include a support plate 1322 positioned to correspond to the upper surface of the multibar 1310 and an expandable section 1324 (e.g., an interlocking section) positioned to correspond to the gap (d) formed between the multibar 1310. At least a portion of the support plate 1322 can be uniformly cut open to form the expandable section 1324. When the bendable section of the display 610 (e.g., the bendable section 610b in Figure 10) moves in the x-axis direction via the bend 601, a compressive force is applied, narrowing the gap (d) between the multibars 131. When the gap (d) between the multibars 1310 narrows, interference between the multibars 1310 can occur, and local tensile stress can be generated in the gap between the multibars 1310. The expandable section 1324 allows the bendable member to bend flexibly, reducing interference between the multibars 1310 due to the compressive and tensile stresses applied to the multibars 1310, thereby reducing the lifting of the bending plate 1320. For example, if a bending plate 1320 is not placed between the display 610 and the multiple multi-bars 1310, the spacing between the multi-bars 1310 narrows at the bend, which can cause a compressive force to be applied to the display 610, potentially causing it to lift up in at least a portion of its length. By placing a bending plate 1320, including a support plate 1322 and an expansion / contraction section 1324 (e.g., an interlocking section), between the display 610 and the multiple multi-bars 1310, the compressive force that can be applied to the display 610 even when the spacing between the multi-bars 1310 narrows at the bend can be reduced, preventing defects such as the display 610 lifting up or deformation.

[0116] Figure 15a is a drawing showing a multibar of a bendable member according to various embodiments of the present disclosure. Figure 15b is a drawing showing how interference between the multibars is avoided when the bendable member moves across a curved surface. Figure 15c is a drawing showing the shape of the multibars to avoid interference between the multibars when the bendable member moves across a curved surface.

[0117] Referring to Figures 15a to 15c, the multibars 1310 can be arranged at regular intervals (for example, interval (d) in Figure 14) so ​​that no interference occurs between the multibars 1310 in the bendable section of the display 610 (for example, the bendable section 610b in Figure 10). A regular interval (d) is formed between the multibars 1310 so that the display 610 can realize a curved shape in the bendable section (for example, the bendable section 610b in Figure 10).

[0118] According to one embodiment, compressive and tensile stresses can be applied to portions of the multibars 1310 where there is a certain interval (d) between them, and expansion and contraction sections (e.g., expansion and contraction sections 1324 in Figures 13 and 14) of the bending plate (e.g., bending plate 1320 in Figure 14) can be arranged to correspond to the interval (d). As the interval between the multibars 1310 narrows in the bendable section (e.g., bendable section 610b in Figure 10), the compressive force that can be applied to the display 610 can be reduced by the expansion and contraction sections (e.g., interlocking sections) (e.g., expansion and contraction sections 1324 in Figures 13 and 14).

[0119] According to one embodiment, in order to realize the curved shape of the display 610 in a bendable section (for example, the bendable section 610b in Figure 10), the multibar 1310 can be formed such that the first width (w1) of the upper surface 1311 and the second width (w2) of the lower surface 1312 are different. The first width (w1) of the upper surface of the multibar 1310 can be formed to be wider than the second width (w2) of the lower surface. A side surface 1313 can be positioned between the upper surface 1311 and the lower surface 1312 of the multibar 1310, and the side surface 1313 can be formed to be inclined at a certain angle (A). For example, the side surface 1313 can be formed to be at an angle of 100 to 110° such that the upper surface 1311 is wider than the lower surface 1312.

[0120] According to one embodiment, when the multibar 1310 undergoes curved surface motion, the corner 1311a of the upper surface 1311 of the multibar 1310 can be formed to have a constant curvature (e.g., 0.2R) (e.g., rounded shape) in order to avoid or reduce interference between the multibars 1310. Similarly, the corner 1312a of the lower surface 1312 of the multibar 1310 can also be formed to have a constant curvature (e.g., 0.2R) (e.g., rounded shape).

[0121] Figure 16 is a drawing showing a bending plate according to various embodiments of the present disclosure, positioned between a display and a bendable member. Figure 17a is a drawing showing the configuration of a bending plate according to various embodiments of the present disclosure. Figure 17b is a drawing showing a multibar 622 bonded to the bottom of the bending plate. Figure 17c is a drawing showing the support plate and expansion section of the bending plate.

[0122] Referring to Figures 16 to 17c, a bending plate 1620 can be positioned between the multibar 1610 and the display 610 of a bendable member (e.g., the bendable member 620 in Figure 8). The support plate 1622 of the bending plate 1620 can be positioned between the top surface of the multibar 1610 and the display 610. The extension section 1624 (e.g., the interlocking section) of the bending plate 1620 can be positioned to correspond to the spacing (d) between the multibars 1610. For example, the multibar 1610 can be positioned so as to overlap at least with the support plate 1622 of the bending plate 1620 (e.g., positioned vertically and overlapping with respect to the z-axis direction in Figures 2, 3, and 6). At least a portion of the multibar 1610 can be positioned so as to overlap at least a portion of the extension section 1624 of the bending plate 1620. For example, in a bent section (e.g., the bent section 601 in Figure 10), the spacing between the multibars 1310 narrows to form a bend, while the expandable section 1624 of the bending plate 1620 allows the bendable section (e.g., the bendable section 610b in Figure 10) to flexibly bend the bendable member (e.g., the bendable member 620 in Figure 8) and the display 610, thereby forming a curved section.

[0123] In one embodiment, a first adhesive member 1630 (e.g., adhesive tape) can be placed on the upper surface of the bending plate 1620. The first adhesive member 1630 can be placed over the entire upper surface area of ​​the bending plate 1620. The bending plate 1620 can be attached to the lower surface of the display 610 by the first adhesive member 1630. For example, the first adhesive member 1630 can be attached to the entire upper surface of the bending plate 1620.

[0124] According to one embodiment, a plurality of second adhesive members 1640 (e.g., adhesive tape) can be placed on the lower surface of the bending plate 1620. The plurality of second adhesive members 1640 can be placed on the portion of the lower surface of the bending plate 1620 corresponding to the support plate 1622 (e.g., the portion corresponding to the upper surface of the multi-bar 1610). The bending plate 1620 can be attached to the upper surface of the multi-bar 1610 by the second adhesive members 1640.

Figure 18b shows how the bendable member and the bending plate are attached using a welding method. Figure 18c shows how the bendable member and the bending plate are attached using a bonding method.

[0126] Referring to Figure 18a, the bending plate 1810 may include a support plate 1812 and an expandable section 1814. The bending plate 1810 can be attached to the upper surface of the bendable member 620. In one embodiment, the bending plate 1810 can be attached to the upper surface of the multi-bar of the bendable member 620 by a taping method using adhesive tape 1820 (e.g., double-sided adhesive tape) (e.g., the second adhesive member 1340 in Figure 13, the multiple second adhesive members 1640 in Figure 16). The adhesive tape 1820 (e.g., double-sided adhesive tape) (e.g., the second adhesive member 1340 in Figure 13, the multiple second adhesive members 1640 in Figure 16) can be placed on the portion of the multi-bar of the bendable member 620 that overlaps with it (e.g., arranged vertically and overlapping with respect to the z-axis direction in Figures 2, 3, and 6) to attach the bending member 620 and the bending plate 1810.

[0127] Referring to Figure 18b, the bending plate 1810 may include a support plate 1812 and an expansion / contraction section 1814. The bending plate 1810 can be attached to the upper surface of the bendable member 620. In one embodiment, the bending plate 1810 can be attached to the upper surface of the multibar of the bendable member 620 by welding. Multiple welding points 1830 can be formed between the multibar and the support plate 1812 to attach the bendable member 620 and the bending plate 1810.

[0128] Referring to Figure 18c, the bending plate 1810 may include a support plate 1812 and an expandable section 1814. The bending plate 1810 can be attached to the upper surface of the bendable member 620. In one embodiment, the bending plate 1810 can be attached to the upper surface of the multibar of the bendable member 620 by a bonding method. Multiple bonding regions 1840 can be formed between the multibar and the support plate 1812 to attach the bendable member 620 and the bending plate 1810.

The bending plate 1920 can be made of metal or rubber (e.g., urethane, LSR (liquid silicone rubbers)) and may include a uniformly cut lattice pattern (e.g., the expandable section 1624 in Figure 17) on at least a portion of the plate (e.g., the support plate 1622 in Figure 17a). The bending plate 1920 can be placed between the multibars 1910 and attached to the multibars 1910. An adhesive member 1930 (e.g., adhesive tape) can be placed on top of the multibars 1910 and the bending plate 1920. The adhesive member 1930 can be placed between the display 610 and the multibars 1910 and between the display 610 and the bending plate 1920. The multibars 1910 can be connected by the bending plate 1920 and the adhesive member 1930. The multibars 1910 and the bending plate 1920 can be attached to the underside of the display 610 by the adhesive member 1930.

[0131] Figure 20 is a drawing illustrating the configuration of a bending plate according to various embodiments of the present disclosure.

[0132] Referring to Figure 20, the multibars 2010 of the bendable member (e.g., the bendable member 620 in Figure 8) can be arranged at regular intervals (d). Bending plates 2020 can be placed in the intervals (d) between the multibars 2010 of the bendable member (e.g., the bendable member 620 in Figure 8). The bending plates 2020 may include support plates with flat top and bottom surfaces (e.g., support plate 1622 in Figure 17a). The bending plates 2020 can be made of metal or rubber (e.g., urethane, LSR (liquid silicone rubbers)). The bending plates 2020 can be made of a material that is flexible to compressive and tensile stresses and has little change in thickness when subjected to compressive and tensile stresses.

[0133] In one embodiment, an adhesive member 2030 (e.g., adhesive tape) can be placed on top of the multi-bar 2010 and the bending plate 2020. The adhesive member 2030 can be placed between the display 610 and the multi-bar 2010 and between the display 610 and the bending plate 2020. The multi-bar 2010 can be connected by the bending plate 2020 and the adhesive member 2030. The multi-bar 2010 and the bending plate 2020 can be attached to the underside of the display 610 by the adhesive member 2030.

[0134] Figure 21 is a drawing illustrating a bendable member according to various embodiments of the present disclosure. Figure 22 is a drawing illustrating a method for forming a bendable member according to various embodiments of the present disclosure.

[0135] Referring to Figures 21 and 22, the bendable member 2100 can be formed in a form in which a multibar (for example, the multibar 1610 in Figure 16) and a bending plate (for example, the bending plate 1620 in Figure 16) are integrated.

[0136] According to one embodiment, the bendable member 2100 may include a plurality of multibars 2110 and a plurality of bending sections 2120. The bending sections 2120 can be arranged between each of the plurality of multibars 2110. The plurality of multibars 2110 may be formed to have a first thickness (h1), and the plurality of bending sections 2120 may have a second thickness (h2) that is thinner than the first thickness (h1). The upper surfaces of the plurality of multibars 2110 and the upper surfaces of the plurality of bending sections 2120 may be located on substantially the same plane. The bending sections 2120 are formed to be thin with a second thickness (h2), and the bendable member 2100 can flexibly bend in a bendable section (for example, the bendable section 610b in Figure 10) to embody the curved shape of the display 610.

[0137] In one embodiment, when forming the bendable member 2100, multiple multi-bars 2110 can be formed by cutting a metal material, and multiple bending portions 2120 can be formed by selectively etching the portions between the multiple multi-bars 2110 to reduce their thickness.

[0139] As one embodiment, when forming the bendable member 2100, a multi-bar 2110 and a bending portion 2120 can be formed by double injection molding of a metal material or a rubber (e.g., urethane, LSR) material.
