[0025] Figure 1 This is a block diagram illustrating an electronic device 101 in a network environment 100 according to various embodiments.

[0026] Figure 1 This is a block diagram illustrating an electronic device 101 in a network environment 100 according to various embodiments. (Refer to...) Figure 1 In network environment 100, electronic device 101 can communicate with electronic device 102 via a first network 198 (e.g., a short-range wireless communication network), or with at least one of 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. According to an embodiment, electronic device 101 may include a processor 120, memory 130, input module 150, sound output module 155, display module 160, audio module 170, sensor module 176, interface 177, connection terminal 178, haptic module 179, camera module 180, power management module 188, battery 189, communication module 190, user identification module (SIM) 196, or antenna module 197. In some embodiments, at least one of the above components (e.g., connection terminal 178) may be omitted from electronic device 101, or one or more other components may be added to electronic device 101. In some embodiments, some of the components described above (e.g., sensor module 176, camera module 180, or antenna module 197) may be implemented as a single integrated component (e.g., display module 160).

[0027] 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 one embodiment, as at least part of the data processing or calculation, 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 result data in non-volatile memory 134.

For example, when electronic device 101 includes a main processor 121 and an auxiliary processor 123, the auxiliary processor 123 may be adapted to consume less power than the main processor 121, or 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 part of the main processor 121.

[0028] 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. Artificial intelligence models can be generated through machine learning. For example, such learning can be performed via electronic device 101 where artificial intelligence is performed or via a separate server (e.g., server 108). The learning algorithm may include, but is not limited to, supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning. The artificial intelligence model may include multiple layers of artificial neural networks. The artificial neural network may be a deep neural network (DNN), a convolutional neural network (CNN), a recurrent neural network (RNN), a restricted Boltzmann machine (RBM), a deep belief network (DBN), a bidirectional recurrent deep neural network (BRDNN), or a deep Q-network, or a combination of two or more thereof, but is not limited thereto. Additionally or optionally, the artificial intelligence model may include software structures in addition to hardware structures.

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

[0033] 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 adapted to detect touch or a pressure sensor adapted to measure the intensity of the force caused by touch.

[0034] The audio module 170 can convert sound into electrical signals and vice versa.

[0035] Sensor module 176 can detect the operating state of electronic device 101 (e.g., power or temperature) or the environmental state outside electronic device 101 (e.g., user 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, gyroscope sensor, atmospheric pressure sensor, magnetic sensor, accelerometer, grip sensor, proximity sensor, color sensor, infrared (IR) sensor, biometric sensor, temperature sensor, humidity sensor, or illuminance sensor.

[0036] Interface 177 may support one or more specific protocols used to enable electronic device 101 to connect directly (e.g., wired) or wirelessly to external electronic devices (e.g., electronic device 102). According to embodiments, interface 177 may include, for example, a High Definition Multimedia Interface (HDMI), a Universal Serial Bus (USB) interface, a Secure Digital Card (SD) interface, or an audio interface.

According to embodiments, connection end 178 may include, for example, an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).

[0038] The tactile module 179 can convert electrical signals into mechanical stimuli (e.g., vibration or motion) or electrical stimuli that can be recognized by a user through his touch or kinesthesia. According to embodiments, the tactile module 179 may include, for example, a motor, a piezoelectric element, or an electrical stimulator.

[0039] 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.

[0040] 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).

[0041] Battery 189 can power at least one component of electronic device 101. According to an embodiment, battery 189 may include, for example, a non-rechargeable primary battery, a rechargeable rechargeable battery, or a fuel cell.

[0042] 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 support 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). One of these communication modules can communicate with an external electronic device via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wi-Fi Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, 5G network, next-generation communication network, the Internet, or a computer network (e.g., a 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 (e.g., multiple chips) that are separate from each other. The wireless communication module 192 can identify and verify the electronic device 101 in the communication network (such as the first network 198 or the second network 199) using user information (e.g., the International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.

[0043] Antenna module 197 can transmit or receive signals or power to or from the outside of electronic device 101 (e.g., external electronic device). According to an embodiment, antenna module 197 may include an antenna comprising a radiating element formed of a conductive material or conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)). According to an embodiment, antenna module 197 may include multiple antennas (e.g., an array antenna). 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 (e.g., wireless communication module 192). Signals or power can then be transmitted or received between communication module 190 and the external electronic device via the selected at least one antenna.

[0044] 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)).

[0045] 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. Each of electronic device 102 or electronic device 104 can 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 that would be performed on electronic device 101 can be performed on one or more of external electronic devices 102, external electronic devices 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 at least a portion of the requested 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.

[0046] The electronic device according to various embodiments can be one of a variety of types of electronic devices. Electronic devices may include, for example, portable communication devices (e.g., smartphones), computer devices, 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.

Figure 2b This is a rear perspective view of an electronic device 200 in a closed state according to an embodiment. Figure 3a This is a front perspective view of an electronic device 200 in the open state according to an embodiment. Figure 3b This is a rear perspective view of an electronic device 200 in the open state according to an embodiment.

[0053] According to various embodiments, Figure 2a The electronic device 200 may include Figure 1 Electronic device 101.

[0054] refer to Figure 2a , Figure 2b , Figure 3a and Figure 3b In an embodiment, the electronic device 200 may be implemented to extend the screen 2301 in a sliding manner. For example, the screen 2301 may be an area of ​​a flexible display 230 viewed from the outside. Figure 2a and Figure 2b The electronic device 200 is shown in its unextended state with screen 2301. Figure 3a and Figure 3bThe electronic device 200 is shown in an extended state with screen 2301. The extended state is when the slider 220 for sliding movement of display 230 is not in a slid-out state, and can be referred to hereinafter as the "closed state". The extended state is when screen 2301 is extended to its maximum extent and no longer extended by the sliding of slider 220, and can be referred to hereinafter as the "open state". For example, when the electronic device 200 switches from the closed state to the open state, sliding can be a movement of at least a portion of slider 220 in a first direction (e.g., the +x axis direction). According to various embodiments, the open state can be defined as the extended state of screen 2301 compared to the closed state, and screens of various sizes are provided depending on the movement position of slider 220. According to various embodiments, intermediate states can indicate... Figure 2a The closed state and Figure 3a The screen 2301 may include an active area of ​​a flexible display 230 that is visually exposed and capable of outputting images, and the electronic device 200 may adjust the active area according to the movement of the slider 220 or the movement of the flexible display 230. In the following description, the open state may indicate a state in which the screen 2301 is maximized. In one embodiment, it is slidably set... Figure 2a The flexible display 230 provided on the electronic device 200 and the screen 2301 can also be referred to as a "slide-out display" or "expandable display".

[0055] According to an embodiment, the electronic device 200 may include a sliding structure associated with the flexible display 230. For example, if the flexible display 230 is moved a predetermined distance by an external force, the electronic device 200 can switch from an off state to an on state, or from an on state to an off state, without any further external force (e.g., semi-automatic sliding operation) due to the elastic structure included in the sliding structure.

[0056] According to one embodiment, if a signal is generated via an input device included in the electronic device 200, the electronic device 200 can switch from a closed state to an open state, or from an open state to a closed state, via a driving device, such as a motor connected to the flexible display 230. For example, if a signal is generated via a hardware button or software button provided on the screen, the electronic device 200 can switch from a closed state to an open state, or from an open state to a closed state.

[0057] According to various embodiments, if a signal is generated from various sensors such as pressure sensors, the electronic device 200 can switch from a closed state to an open state, or from an open state to a closed state. For example, when the electronic device 200 is carried or grasped by a hand, the sensor can sense a squeezing gesture of a part of the hand (e.g., palm or fingers) pressing a designated part of the electronic device 200, and correspondingly, the electronic device 200 can switch from a closed state to an open state, or from an open state to a closed state.

[0058] According to an embodiment, the display 230 may include a second part ② (see embodiment 2). Figure 3a When the electronic device 200 switches from an off state to an on state, the second part ② may include an extended portion of the screen 2301. When the electronic device 200 switches from an off state to an on state, the second part ② can be slidably withdrawn from the internal space of the electronic device 200, thus expanding the screen 2301. When the electronic device 200 switches from an on state to an off state, at least a portion of the second part ② can be slidably drawn into the internal space of the electronic device 200, thus retracting the screen 2301. When the electronic device 200 switches from an on state to an off state, at least a portion of the second part ② can be bent and moved into the internal space of the electronic device 200. For example, the flexible display 230 may include a flexible substrate (e.g., a plastic substrate) formed of a polymer material including polyimide (PI) or polyester (PET). The second part ② is a bent portion of the flexible display 230 when the electronic device 200 switches between an on state and an off state, and may be referred to as, for example, a bendable portion. In the following description, the second part ② will be referred to as a bendable portion.

[0059] According to an embodiment, the electronic device 200 may include a housing 210, a sliding plate 220, and / or a flexible display 230.

[0060] The housing (or casing) 210 may include, for example, a rear cover 212, a first side cover 213, or a second side cover 214. The rear cover 212, the first side cover 213, or the second side cover 214 may be connected to a support member (not shown) located inside the electronic device 200 and may at least partially form the exterior of the electronic device 200.

[0061] The back cover 212 may form at least a portion of, for example, the rear surface 200B of the electronic device 200. In embodiments, the back cover 212 may be substantially opaque. For example, the back cover 212 may be formed of a coating or colored glass, ceramic, polymer, metal (e.g., aluminum, stainless steel (STS), or magnesium), or a combination of at least two of the above materials. According to one embodiment, when the flexible portion ② of the flexible display 230 is retracted into the internal space of the housing 210 (e.g., in a closed state), at least a portion of the flexible portion ② may be configured to be visible from the outside through the back cover 212. In this case, the back cover 212 may be formed of a transparent and / or translucent material.

[0062] According to an embodiment, the back cover 212 may include a planar portion 212a and curved portions 212b and 212c located on opposite sides of each other, with the planar portion 212a interposed between the two.

For example, as an elastic structure 401, a torsion spring may include a portion connected to one end of the sliding plate 220, a portion connected to the other end of the first support member 410, and a spring portion between the one end portion and the other end portion. If the sliding plate 220 moves a predetermined distance in a first sliding direction (e.g., the +x axis direction) by an external force, the position of one end portion relative to the other end portion changes, so that even without any further external force, the sliding plate 220 can move in the first direction due to the elasticity of the spring portion, thereby allowing the sliding plate 220 to move from the open state to the closed state. Figure 2a Switching to the off state Figure 3a The sliding plate 220 is in the open state. If the sliding plate 220 is moved a predetermined distance in a second direction (e.g., the -x-axis direction) opposite to the first direction by an external force, the position of one end portion relative to the other end portion changes. Therefore, even without any further external force, the sliding plate 220 can move in the second direction due to the elasticity of the spring portion, so that the sliding plate 220 can be moved from the open state.

According to an embodiment, the second surface 482 may include a plurality of extension bars (not shown) arranged in a shape pointing from a second axis of rotation 463 of the pulley 460 to a first axis of rotation (not shown) (e.g., the +y axis direction). The multi-bar structure 480 may be bent at portions of relatively thin thickness among the plurality of bars. In various embodiments, the multi-bar structure 480 may be referred to by another term, such as "flexible track" or "hinge rail".

[0091] According to an embodiment, in Figure 2a The closed state or Figure 3a In the open state, at least a portion of the multi-bar structure 480 can overlap with the screen 2301 (see...). Figure 2a or Figure 3aThe multi-bar structure 480 can support the flexible portion ②, ensuring that the flexible portion ② of the flexible display 230 remains smoothly connected to the first portion ① of the flexible display 230 without unfastening (or detachment). The multi-bar structure 480 can facilitate the movement of the flexible portion ② within... Figure 2a The closed state and Figure 3a During the switching between open states, a smooth connection with the first part ① is maintained without loosening.

[0092] According to an embodiment, the support sheet 470 can make components located inside the electronic device 200 (e.g., the multi-bar structure 480) substantially invisible through the flexible display 230.

[0093] In extended screen mode (e.g., Figure 3a In the open state, the flexible display 230 and / or support sheet 470 may loosen due to elasticity, potentially resulting in an uneven screen. According to various embodiments, to mitigate this, a stretching structure (not shown) may be provided for the flexible display 230 and / or support sheet 470. The stretching structure can help smooth sliding operations while maintaining stretch.

[0094] According to an embodiment, the processor (e.g., Figure 1 The processor 120), memory (e.g., Figure 1 The memory 130) and / or interface (e.g., Figure 1 The interface 177 can be mounted on the printed circuit board 490. The processor may include one or more of, for example, a central processing unit, an application processor, a graphics processing device, an image signal processor, a sensor hub processor, or a communication processor.

[0095] The memory may include, for example, volatile or non-volatile memory. The interface may include, for example, a High Definition Multimedia Interface (HDMI), a Universal Serial Bus (USB) interface, an SD card interface, and / or an audio interface. The interface can electrically or physically connect the electronic device 200 to an external electronic device and may include a USB connector, an SD card / MMC connector, or an audio connector.

[0096] Electronic device 200 may include various other components disposed on or electrically connected to printed circuit board 490. For example, electronic device 200 may include a battery (not shown) located between first support member 410 and second support member 420 or between second support member 420 and rear cover 212. The battery (not shown) is a device for supplying power to at least one component of electronic device 200 and may include, for example, a non-rechargeable primary battery, a rechargeable rechargeable battery, or a fuel cell. The battery (not shown) may be integrally disposed within electronic device 200 or may be detachably disposed with electronic device 200. According to an embodiment, electronic device 200 may include an antenna (not shown) located between first support member 410 and second support member 420 or between second support member 420 and rear cover 212. The antenna (not shown) may include, for example, a near-field communication (NFC) antenna, a wireless charging antenna, and / or a magnetically secure transmission (MST) antenna. The antenna (not shown) may perform, for example, short-range communication with external devices or wirelessly transmitting and receiving power required for charging. In another embodiment, the antenna structure may be formed by a portion of the first side cover 213 and / or the second side cover 214, or a combination thereof.

[0097] According to an embodiment, the electronic device 200 may include a flexible printed circuit board (FPCB) 237 that electrically connects the flexible display 230 and the printed circuit board 490 to each other. For example, the flexible printed circuit board 237 may be electrically connected to the printed circuit board 490 through an opening (not shown) formed on the sliding plate 220 and an opening (not shown) formed on the first support member 410.

[0098] Figure 5 It is in accordance with the embodiments Figure 2a A cross-sectional view of a portion of the electronic device 200 along line A-A' in the off state. Figure 6 It is in accordance with the embodiments Figure 3a A cross-sectional view of a portion of the electronic device 200 along line B-B' in the open state.

[0099] refer to Figure 5 and Figure 6 The electronic device 200 may include a back cover 212, a first support member 410, a second support member 420, a third support member 430, a sliding plate 220, a flexible display 230, a support sheet 470, a multi-bar structure 480, a printed circuit board 490, and / or a pulley 460. (The details will be omitted.) Figure 5 or Figure 6 The repeated interpretation of some of the figure labels in the illustrations.

[0100] According to an embodiment, the sliding plate 220 may be disposed on the first support member 410 so that it can slide out. The flexible display 230 may include a first portion ① and a bendable portion ②. Figure 5 The closed state or Figure 6 In its open state, screen 2301 may include a planar portion 230a and a first curved portion 230b and a second curved portion 230c located on opposite sides of the planar portion 230a. The first portion ① may be disposed along the planar portion 230a and the first curved portion 230b of screen 2301. A flexible portion ② may extend from the first portion ① and may be extracted from the internal space of the electronic device 200 during sliding out of the slide plate 220. The first curved portion 230b may be formed as a curved surface (not shown) corresponding to a surface formed on one surface of the slide plate 220. The second curved portion 230c may be formed from a portion of the curved surface (not shown) corresponding to the pulley 460 in the flexible portion ②.

[0101] According to one embodiment, the support sheet 470 may be disposed on the rear surface of the flexible display 230. According to another embodiment, the support sheet 470 may be included within the flexible display 230. The pulley 460 may be located inside the electronic device 200 and may be connected to the flexible portion ② of the flexible display 230. A multi-bar structure 480 may extend from the sliding plate 220 between the support sheet 470 and the pulley 460. The multi-bar structure 480 may facilitate the movement of the movable flexible portion ②. Figure 5 The closed state and Figure 6 During the switching between open and closed states, a smooth connection with the first part ① is maintained without loosening. Figure 5 The closed state or Figure 6 In the open state, a portion of the flexible section ② can form the second curved section 230c of the screen 2301, and can be supported by the multi-bar structure 480 between the pulley 460 and the flexible section ②, so as to smoothly connect to the first section ① without loosening. Figure 6 In the open state, a portion 230d of the flexible portion ② can form part of the planar portion 230a of the screen 2301, and can be supported by a multi-bar structure 480 between a surface 410a of the first support member 410 and the flexible portion ②, so as to be smoothly connected to the first portion ① without loosening.

[0102] According to various embodiments (not shown), instead of pulley 460, a curved member including a curved portion contacted by the multi-bar structure 480 can be provided. For example, in Figure 5 The closed state and Figure 6During the switching between open and closed states, the multi-bar structure 480 can slide relative to the curved portion. According to various embodiments, to reduce friction between the curved portion and the multi-bar structure 480, the surface of the curved portion or the surface of the multi-bar structure 480 can be surface-treated. According to various embodiments, the curved member can be connected to... Figure 4 The support structure 400. According to one embodiment, the pulley 460 can be defined as a curved member that is rotatably realized based on friction with the multi-bar structure 480. According to one embodiment (not shown), a track portion (not shown) for guiding the movement of the multi-bar structure 480 can be implemented instead of the curved member, or can be formed along the curved portion of the curved member. The track portion can be formed in, for example... Figure 2a On the outer casing 210 or Figure 4 The support member 440 is mounted on the support member assembly 400. According to an embodiment, the fourth support member 440 may include a first track portion into which one side portion of the multi-bar structure 480 is inserted to guide movement of the multi-bar structure 480. The fifth support member 450 may include a second track portion into which the other side portion of the multi-bar structure 480 is inserted to guide movement of the multi-bar structure 480.

[0103] According to various embodiments, the electronic device 200 may not be limited to Figure 4 , Figure 5 or Figure 6 Instead of the traditional embodiment, it can be implemented in such a way that when the sliding plate 220 slides out, the portion of the flexible display 230 that has been rolled up on the rollers located inside the electronic device (e.g., the flexible portion ②) comes out and is unfolded to expand the screen.

[0104] According to an embodiment, the flexible portion ② of the flexible display 230, the flexible portion (not shown) of the support sheet 470 corresponding to the flexible portion ②, and the multi-bar structure 480 can be connected to the pulley 460. The movement and direction of movement of the flexible portion ② of the flexible display 230, the flexible portion of the support sheet 470, and the multi-bar structure 480 can be guided by the pulley 460. The multi-bar structure 480 can face the roller 461 of the pulley 460 (see...). Figure 4The flexible portion of the support plate 470 can be located between the multi-bar structure 480 and the flexible portion ② of the flexible display 230. Since the flexible portion of the support plate 470 does not directly face and contact the pulley 460, but moves based on the rotation of the pulley 460 through a driving relationship with the pulley 460 corresponding to the multi-bar structure 480, the flexible portion of the support plate 470 can be described as being in a connected state (or a driven connection state) with the pulley 460. Since the flexible portion ② of the flexible display 230 does not directly face and contact the pulley 460, but moves based on the rotation of the pulley 460 through a driving relationship with the pulley 460 corresponding to the multi-bar structure 480 and the flexible portion of the support plate 470, the flexible portion ② of the flexible display 230 can be described as being in a connected state (or a driven connection state) with the pulley 460.

[0105] According to an embodiment, the electronic device 200 may include a tensioning structure (or tensioning device) (not shown) for the flexible display 230 and / or the support sheet 470. The tensioning structure may be connected to, for example, the support sheet 470 and may provide tension (or tensile force) T to the flexible display 230 and / or the support sheet 470, which are in a driven connection with pulleys 460. The tensioning structure may apply tension T to the support sheet 470 attached to the flexible display 230.

[0106] According to the embodiment, when the tension T of the tension structure is within the critical range, the bendable portion ② can... Figure 5 The closed state or Figure 6 In its open state, it maintains a smooth connection with the first part ① without loosening. When the tension T of the tensile structure is within the critical range, in Figure 5 The closed state and Figure 6 During the switching between open and closed states, the flexible part ② can be in Figure 5 The closed state or Figure 6 In its open state, it moves while maintaining a smooth connection with the first part ① without loosening. When the tension T of the tensile structure is within the critical range, Figure 5 The closed state and Figure 6 During the transition between open and closed states, the sliding operation can be performed smoothly.

[0107] For example, the tension T of the tensile structure may be below a critical range. In this case, due to the elasticity of the flexible display 230 and / or the support sheet 470, the bendable part ② may loosen or may not be able to connect smoothly to the first part ①.

[0108] As another example, the tension T in a tensile structure can exceed a critical range. In this case, although the flexible part ② can be smoothly connected to the first part ① without loosening, Figure 5 The closed state and Figure 6 During the switching between open and closed states, it may be difficult to perform a smooth sliding operation. If the tension applied to the support plate 470 attached to the flexible display 230 is higher than the critical range, the load on the rotation axis of the pulley 460 will exceed the critical value, increasing the rotational resistance of the pulley 460, thus making a smooth and gentle sliding operation difficult.

[0109] While the tension T acting on the flexible display 230 and / or the support sheet 470 remains within a critical range, it may be difficult to assemble the tension structure and related components (e.g., electromechanical components) in the electronic device 200. Due to the repetition of sliding operations, the tension T acting on the flexible display 230 and / or the support sheet 470 may fall below the critical range.

[0110] Figure 7 According to the embodiments Figure 2a A block diagram of an electronic device.

[0111] refer to Figure 7 The electronic device may include a display 720, a camera 730, a motor module 740, a contact sensor 750, and a processor 710, and some of the components shown in the various embodiments may be omitted or replaced. The electronic device may also include... Figure 1 The electronic device contains at least some of its constructions and / or functions. At least some of the illustrated (or not shown) constructions of the electronic device may be operatively, functionally, and / or electrically interconnected. According to various embodiments, a contact sensor 750 (e.g., a touch sensor) may be included in the display 720. For example, the function of the contact sensor 750 may be established in the liquid crystal panel (not shown) of the (in-cell) display 720, or the function of the contact sensor 750 may be established between the color filter substrate (not shown) and the polarizer (not shown) of the (in-cell) display 720, or the function of the contact sensor 750 may be included on top of the liquid crystal panel (not shown) of the (on-cell) display 720.

[0112] According to various embodiments, the display 720 can display various images under the control of the processor 710. The display 720 can be implemented using any of, but is not limited to, liquid crystal displays (LCDs), light-emitting diode (LED) displays, and organic light-emitting diode (OLED) displays. The display 720 can consist of a touchscreen that senses touch and / or proximity touch (or hover) input using a user's body part (e.g., a finger) or an input device (e.g., a stylus). The display 720 may include... Figure 1 The display module has at least some of its construction and / or functions.

[0113] According to various embodiments, the display 720 may be at least partially flexible and may be implemented as a foldable or rollable display.

[0114] According to various embodiments, camera 730 can acquire external image data. Camera 730 can acquire image data by using a charge-coupled device (CCD) type or complementary metal-oxide-semiconductor (CMOS) type image sensor. In the electronic device, one or more cameras can be disposed on the front and / or rear surface of the housing, and hereinafter, unless otherwise stated, image data including the user's eye area can be image data acquired by using a rear camera.

[0115] According to various embodiments, camera 730 can capture an image of a subject by zooming in or zooming out. The camera can perform zooming in and / or zooming out using at least one of optical zoom and digital zoom. Optical zoom is used to adjust the focus position, angle of view, and / or size of the subject in the captured image by moving the optical lens back and forth. Digital zoom is used to adjust the angle of view and / or size of the subject in the image provided to the user by cropping and expanding a preview image obtained by the charge-coupled device (CCD) in digital signal processing. According to embodiments, during zooming in, camera 730 can additionally zoom in on the object by using digital zoom with the maximum size (or minimum angle of view) (e.g., 50x) in the zoomed-in state.

[0116] According to various embodiments, when performing zoom in and / or zoom out, camera 730 can provide an optical zoom effect by switching between multiple cameras with different perspectives. For example, the cameras of the electronic device may include a first wide-angle camera, a second wide-angle camera that captures a wider angle than the first wide-angle camera, and a third wide-angle camera that captures a wider angle than the second wide-angle camera. If the user increases the magnification while using the first wide-angle camera, optical zoom can be performed by switching to the second wide-angle camera. If the user further increases the magnification while using the second wide-angle camera, optical zoom can be performed by switching to the third wide-angle camera.

[0117] According to various embodiments, the motor module 740 can extend the rollable display of the electronic device. For example, the motor module 740 can pull out the retracted, bendable portion ② of the display 720 based on user touch input. Conversely, the motor module 740 can retract the retracted display 720 back into the housing. The motor module 740 can receive extension information calculated by the processor 710 based on a scaling factor, and extend the display 720 based on the received extension information (e.g., control signals for controlling the opening and / or closing of the display). The extension information may include control signals for the motor module to control the opening or closing of the display.

[0118] According to various embodiments, the motor module 740 can expand the display 720 to match the user's pinch-to-zoom speed. For example, if the user zooms the display 720 to its maximum magnification within two seconds, the processor 710 can receive information about the touch input from the touch sensor 750 in real time and calculate the zoom ratio. The processor can send expansion information to the motor module 740 to expand the display at the maximum magnification within two seconds, the expansion information being calculated based on the calculated zoom ratio. The motor module can receive the expansion information and expand the display 720 to its maximum length within two seconds. According to another embodiment, the motor module 740 can expand the display 720 after the zoom ratio has been determined. That is, the processor can calculate the zoom ratio after the touch input ends, generate expansion information, and send it to the motor module, which can then expand the display 720 to the length indicated by the expansion information.

[0119] According to various embodiments, the motor module can be configured to expand the display only up to a specified maximum expansion length. According to embodiments, the scaling factor when the display is expanded to the maximum expansion length can be less than the maximum scaling factor. For example, the maximum scaling factor (optical scaling factor and digital scaling factor) provided by the camera module can be configured to be 50.0x, the maximum expansion length of the display is 10 cm, and the scaling factor is expanded to up to 30.0x when only the display is expanded to the maximum expansion length. If, after the display has been expanded to the maximum expansion length, the digital scaling factor and / or optical scaling factor of the camera is additionally increased by a user's pinch-to-zoom gesture, the display is no longer expanded further, and the processor can enlarge the image according to the scaling factor.

[0120] According to various embodiments, the contact sensor 750 (e.g., a touch sensor) can sense touch input from a user. The user can zoom in or out of a specific portion of the preview via touch input. The user's touch input can include, for example, a pinch-to-zoom gesture for a camera preview or a touch and drag gesture for zooming a guide bar. A pinch-to-zoom gesture can be a gesture of touching and dragging two touch points to increase or decrease the distance between the two touch points. According to embodiments, the zoom guide bar is a long strip and can be located on one side of the display 720, and can include a graphic indicating the current zoom level. If the zoom level with the maximum extended length of the display is less than the maximum zoom level, the zoom guide bar can additionally include a graphic object indicating the zoom level with the maximum extended length of the display. The contact sensor 750 can sense touch input as described above and send information about it to the processor 710.

[0121] According to various embodiments, processor 710 may be configured to be operatively, functionally, and / or electrically connected to corresponding component elements (e.g., display 720, camera 730, motor module 740, and / or contact sensor 750), and is capable of performing calculations or data processing related to the control and / or communication of the corresponding component elements. Processor 710 may include Figure 1 The processor 120 has at least some of its construction and / or functions.

[0122] According to various embodiments, the computation and data processing that can be implemented by the processor 710 on the electronic device are not limited, but various embodiments for expanding the rollable display of the electronic device based on user touch input will be described below. The operation of the processor 710, which will be described later, can be executed by loading instructions stored in memory.

[0123] According to various embodiments, processor 710 operates camera 730. Camera 730 can capture images of a subject in front and convert the captured images into image data, which processor 710 displays on display 720, for example, in preview form. According to embodiments, processor 710 can perform image capture by using a single camera or multiple cameras. When using a single camera, processor 710 can be configured (e.g., with zoom folding) to use both optical zoom and digital zoom simultaneously. For example, a single camera can perform optical zoom up to a specified zoom level, and if the zoom level exceeds the specified zoom level, the image of the subject can be captured by performing digital zoom.

[0124] According to various embodiments, if the processor 710 performs image capture via a single camera, it can be configured to expand the display 720 up to a maximum extended length as the zoom level increases while performing optical zoom. If the zoom level exceeds a specified zoom level for optical zoom, optical zoom is switched to digital zoom, and the display 720 cannot be expanded further. Subsequently, if the zoom level is additionally increased based on user input, the processor 710 can enlarge the image according to the zoom level and display the enlarged image on the display 720.

[0125] When using multiple cameras, different cameras can be used depending on the zoom level. For example, if the maximum zoom level is 50.0x, the first camera can be used for image capture in the range of 1.0x to 10.0x, the second camera can be used for image capture in the range of 10.0x to 30.0x, and the third camera can be used for image capture in the range of 30.0x to 50.0x. In this case, if the zoom level determined by touch input is 35.0x, the first camera can be used for image capture up to 10.0x, the second camera can be used in the range of 10.0x to 30.0x, and the third camera can be used in the range of 30.0x to 35.0x. According to an embodiment, the user can change the screen magnification ratio based on the number of cameras 730.

[0126] According to various embodiments, processor 710 receives information about user touch input from touch sensor 750. According to embodiments, processor 710 determines a zoom level by utilizing the information about the touch input. The zoom level can represent how much the preview of an object is magnified. For example, if the maximum zoom level of the electronic device is 50.0x, processor 710 can be configured to increase the zoom level by 5.0x whenever the length between two touch points increases by 1 cm via a pinch-to-zoom gesture. If the distance between the touch points increases by 7 cm via a first touch input, the zoom level can be determined to be 35.0x; if the distance between the touch points decreases by 2 cm via a second touch input, the zoom level can be determined to be 25.0x.

[0127] According to another embodiment, touch input may include operations related to a zoom guide bar. Specifically, the zoom guide bar may include at least one of a bar in the form of a strip, scales, a zoom ratio graph, and an indicator line. If the zoom ratio with the maximum extended length of the display is less than the maximum zoom ratio, the zoom guide bar may additionally include a graphic object indicating the zoom ratio with the maximum extended length of the display 720. For example, if the zoom ratio with the maximum extended length is 10.0x, the portion of the zoom guide bar corresponding to 10.0x may be displayed in a different color. The scales may be displayed along with the bar and may be displayed at a distance so that the user can easily know the zoom ratio at the corresponding position. The zoom ratio graph may be displayed on one side of the bar and may display graphic information about the zoom ratio corresponding to that position. According to an embodiment, if the zoom guide bar is set to be horizontally long, the zoom ratio may be configured to increase from left to right. However, the embodiment is not limited to this, and the zoom ratio may increase from right to left, or if the bar is set to be vertically long, the zoom ratio may be configured to increase from bottom to top. The indicator line may be located inside the bar and may indicate information about the current zoom ratio. Users can adjust the zoom level by touching and dragging the indicator line. For example, if a user wants to change the current zoom level from 10.0x to 25.0x, the user can touch the indicator line at the 10.0x position and drag it to the position corresponding to 25.0x. After determining the zoom level, the processor 710 enlarges the image to match the determined zoom level, generates extended information including control signals for controlling the display to turn on or off, and sends the generated extended information to the motor module 740.

[0128] According to various embodiments, the processor 710 can perform the operation of reducing the size of the display 720 based on a user's pinch-to-zoom gesture or operation on the zoom guide bar. For example, when moving the pinch-to-zoom gesture or the indicator line of the zoom guide bar to the left (or right), the zoom level can be reduced, and the display 720 can be reduced by transmitting extended information calculated based on the reduced zoom level to the motor module 740. The following description includes cases where the image and display 720 are reduced by receiving a pinch-to-zoom or operation on the zoom guide bar.

[0129] According to various embodiments, processor 710 enlarges or shrinks the image to the same extent as a determined scaling factor. That is, processor 710 can enlarge or shrink the image received by camera 730 and display it on display 720. In this case, the image can be enlarged around the center point of the line connecting the two touch points or the center of the display screen. For example, if the user performs a pinch-to-zoom operation, the image can be enlarged around the center point of the line connecting the two touch points. If the user operates a zoom guide bar, a touch point is provided, and the image can be enlarged based on the center of the display screen. The user can view a wider horizontally (or vertically) screen through the enlarged display 720.

[0130] According to various embodiments, processor 710 sends expansion information calculated based on scaling factor to motor module 740. The expansion information may include information about the length of display 720 that should be expanded. The length of display 720 to be expanded can be determined proportionally to the maximum expansion length. For example, if the maximum expansion length of display 720 is 10 cm and the maximum scaling factor is 50.0x, and the scaling factor calculated via the first touch input is 35.0x, then display 720 can be expanded by 7 cm. Subsequently, if the scaling factor calculated via the second touch input is 25.0x, then display 720 can be reduced by 2 cm. Motor module 740 can expand display 720 based on the received expansion information.

[0131] According to various embodiments, at least a portion of the flexible portion extended by the display 720 can be an extended area of ​​the display screen. In this extended area, an image that expands based on user touch input can be displayed.

[0132] According to various embodiments, processor 710 can display animation simultaneously with an image displayed in the extended area. According to embodiments, processor 710 can operate such that during the extension of display 720 via motor module 740, only a black screen is displayed in the extended area, and after extension is complete, processor 710 immediately displays the extended image across the entire area of ​​display 720, including the extended area. For example, if the magnification is increased from 10.0x to 20.0x via user touch input, the extended area may increase when the flexible portion of motor module 740 is withdrawn. During withdrawal, only a black screen is displayed in the extended area, and no image may appear. Furthermore, after extension is complete, the image is expanded to the same magnification as the increased magnification, and the extended image is displayed on display 720.

[0133] According to another embodiment, the processor 710 can first complete and extract the screen in the extended area to be extracted. For example, in the case of extracting a flexible portion based on user touch input, the processor 710 can expand the screen based on a predetermined scaling factor, and can also expand the image simultaneously when extracting the flexible portion. That is, the expansion of the display 720 and the expansion of the image can occur simultaneously.

[0134] According to various embodiments, processor 710 can adjust the center position of the existing display screen that the user is already seeing when the flexible portion is pulled out. For example, if display 720 extends to the right, processor 710 can move the display screen to the right and position the display screen such that the center of display 720 and the center of the screen coincide with each other. According to embodiments, in this case, extended areas can be generated on both side surfaces of the existing display screen.

[0135] According to various embodiments, the processor 710 can extend the display 720 in only one direction, and can extend the display 720 in both lateral directions. For example, if the motor module 740 appears on both side surfaces of the display 720, the display 720 can extend to the right and left simultaneously.

[0136] According to various embodiments, if a user expands the display 720 by applying physical force to it, the same effect as pinch-to-zoom can occur. For example, if the display 720 is expanded by applying force, the processor 710 can calculate a scaling factor based on the expanded length, enlarge the image based on the calculated scaling factor, and move the indicator line of the scaling guide bar. Even when the display 720 is reduced, the opposite effect occurs in the same way, and therefore will not be explained in more detail. Everything described below includes expanding the image by physically expanding the display 720.

[0137] Figure 8a and Figure 8b An electronic device is shown that expands the display via touch input according to various embodiments.

[0138] refer to Figure 8a The display can be expanded based on the user's pinch-to-zoom gestures. Pinch-to-zoom gestures can mean touching and dragging two touch points to narrow or widen the distance between the two touch points. Figure 8a and Figure 8b An embodiment of the display being extended in the lateral direction is shown, but the direction of extension is not limited to this, and the display can be extended in various directions.

[0139] According to various embodiments, if a user performs a pinch-to-zoom gesture, the image is expanded. If the touch sensor 750 senses the user's touch input, the processor 710 can calculate the zoom level by analyzing the information received from the touch sensor 750. The processor 710 can calculate expansion information based on the calculated zoom level and send the calculated expansion information to the motor module 740, which can then expand the display 720 based on the received expansion information. According to embodiments, the processor 710 can provide a wider screen by simultaneously expanding the image and the display 720. According to another embodiment, the indicator line of the zoom guide bar 805 located on one side of the display screen can move together with different zoom levels.

[0140] For example, if the distance between two touch points increases by 1 cm, the zoom ratio can be calculated to increase by 5.0 times. The first zoom display 800 has a zoom ratio of 1.0 times in its unexpanded state, and in this case, if the user performs a 4 cm pinch-to-zoom, the zoom ratio increases to 20.0 times. As a result, the first zoom body 801 is expanded into the second zoom body 811, the first zoom display 800 is expanded into the second zoom display 810, and the indicator line of the zoom guide bar 805 moves to the right, indicating 20.0 times. Similarly, if the user performs a 6 cm pinch-to-zoom, the zoom ratio increases to 50.0 times, and the second zoom body 811 and the second zoom display 810 are expanded into the third zoom body 821 and the third zoom display 820, respectively. With 50.0 times being the maximum zoom ratio, the indicator line of the zoom guide bar 805 continues to move to the right.

[0141] refer to Figure 8b The processor 710 can determine the scaling factor by receiving the operation 807 on the scaling guide 805, thereby enlarging the image and expanding the display 720. Since the operation 807 on the scaling guide 805 is a user-determined scaling factor, the processor 710 does not need to calculate the scaling factor separately. The following is referenced above. Figure 8a As stated above.

[0142] Figure 9 An electronic device is shown in which the display is expanded when using multiple cameras, according to an embodiment.

[0143] refer to Figure 9The processor 710 can capture images of a subject by using multiple cameras that capture images of the subject at different zoom levels. The respective cameras can have different viewing angles. For example, in the case of a maximum magnification of 50.0x for the electronic device, a first camera with the widest viewing angle can handle magnifications from 1.0x to 10.0x, a second camera can handle magnifications from 10.0x to 30.0x, and a third camera with the narrowest viewing angle can handle magnifications from 30.0x to 50.0x. To capture an image of the subject at 40.0x magnification, the user operates the first camera up to 1.0x to 10.0x, the second camera up to 10.0x to 30.0x, and the third camera up to 40.0x. According to an embodiment, flickering may occur on the display screen when the cameras are switched.

[0144] According to various embodiments, if the scaling factor increases based on user touch input, the display 720 also expands to match the corresponding scaling factor. For example, when the user performs a capture using the first camera (900), it may expand by only 1 / 5 of the maximum expansion length; when capturing with the second camera (910), it may expand by only 3 / 5 of the maximum expansion length; and when capturing with the third camera (920), it may expand by the maximum expansion length. Other embodiments are the same as those described above and will therefore be omitted.

[0145] Figure 10a and Figure 10b An electronic device is shown that expands an image when the display is expanded according to an embodiment.

[0146] refer to Figure 10a Users can enlarge images by applying physical force to the display to expand it. According to various embodiments, processor 710 can enlarge or reduce the image by calculating a scaling factor based on the extended length of the display. For example, when a first-magnification subject is displayed on a first-magnification display 1000, the user can enlarge the image by pulling the display to either side. If the maximum scaling factor is 30.0x and the maximum extended length of the display is 10 cm, the user can extend the first-magnification display 1000 (e.g., 4 cm) to a second-magnification display 1010, and in this case, processor 710 can calculate the scaling factor and enlarge the first-magnification subject (e.g., 1.0x) to the second-magnification subject (e.g., 12.0x). If the user further extends (e.g., 10 cm) to a third-magnification display 1020, the image can also be enlarged to the third-magnification subject (e.g., 30.0x).

[0147] According to various embodiments, the scaling factor of the display at its maximum extended length can be configured to be less than the maximum scaling factor. (See reference...) Figure 10bIn the third-magnification display 1020, where the display is in its maximum expanded state, the scaling factor can be less than 10.0 times the maximum scaling factor. Thereafter, even if the user performs a pinch-to-zoom gesture (1030), the display will not expand further. The user can additionally enlarge the image displayed on the screen through the pinch-to-zoom gesture 1030 or by operating the scaling guide bar.

[0148] According to various embodiments, when expanding the display from a first magnification display 1000 to a second magnification display 1010 or from a second magnification display 1010 to a third magnification display 1020 by increasing the magnification, it is possible that no image is displayed in the expanded area when the display is expanded. After the expansion of the display ends, the processor 710 can display the expanded image on the entire display including the expanded area. According to another embodiment, the processor 710 can calculate the scaling factor in real time simultaneously with the expansion of the display. The processor can expand the image in real time based on the calculated scaling factor and display the expanded image in the expanded area.

[0149] According to an embodiment, the display screen may include at least one zoom guide bar 1005. The zoom guide bar 1005 may include at least one of the following: a bar in the form of a scale, a marker line, and a zoom level graph. If the zoom level of the display's maximum extended length is less than the maximum zoom level, the zoom guide bar may additionally include a graphic object indicating the zoom level of the display's maximum extended length. The marker line is a configuration that displays the current zoom level, and if the user changes the zoom level by enlarging the display, the marker line may move accordingly. For example, when capturing an image of a subject at a first zoom level, the marker line is located at the left end of the zoom guide bar 1005, but when performing image capture at a second or third zoom level, the marker line may gradually move to the right end of the zoom guide bar 1005.

[0150] According to various embodiments, although not shown in the figures, if the display is physically reduced, the processor 710 can operate in the opposite manner to what has been described above. That is, the image can be reduced, and the indicator line of the scaling guide bar 1005 can be moved to the left.

[0151] Figure 11 An electronic device with a display that is extended vertically according to an embodiment is shown.

[0152] According to various embodiments, the processor 710 can expand the display horizontally as shown in Figures 2 to 10, and can also expand the display vertically. (Reference) Figure 11 When the user performs a pinch-to-zoom gesture or operates the zoom guide bar, the processor 710 can expand the display vertically and simultaneously enlarge the image based on touch input.

[0153] For example, processor 710 can receive an image of a subject from a camera and display a first magnified subject 1101 on a first magnification display 1100. The first magnified subject 1101 displayed on the first magnification display 1100 can be enlarged to a second magnification object 1111 via user touch input 1113, which includes at least one of a pinch-to-zoom gesture and a zoom guide bar operation. As the image is enlarged, the first magnification display 1100 can also be expanded to a second magnification display 1110 via motor module 740. When the image is reduced to a third magnification subject 1121 via a pinch-to-zoom gesture or a zoom guide bar operation, the second magnification display 1110 is reduced to the third magnification display 1120 via motor module 740. Other operations of processor 710 and motor module 740 are the same as described above and will be omitted.

[0154] According to various embodiments, physically pushing the display upwards can enlarge the image, similar to performing a pinch-to-zoom gesture. Conversely, pulling the display downwards can shrink the image, similar to performing a pinch-to-zoom gesture.

[0155] Figure 12a and Figure 12b A method for expanding a rollable display for an electronic device is shown.

[0156] The method shown can be obtained from the above text. Figures 1 to 11 The described electronic device (e.g., Figure 7 The electronic device 700) performs the operation, and the explanation of the technical features described above will be omitted.

[0157] According to various embodiments, in step 1201, the electronic device may operate camera 730. Camera 730 may capture an image of a subject in front and convert the captured image into image data, and the electronic device may display the corresponding image data on a display in the form of a preview. According to embodiments, the electronic device processor 710 may perform image capture with a single camera in step 1210, or may perform image capture with multiple cameras in step 1220. When using multiple cameras, different cameras may be used according to the zoom level.

[0158] According to various embodiments, if the electronic device uses a single camera, optical scaling and / or digital scaling can be used depending on the scaling factor. For example, optical scaling can be used up to a scaling factor of 5.0x, and if the scaling factor exceeds 5.0x, digital scaling can be used. The display can be configured to expand in response to scaling factors up to 5.0x when optical scaling occurs. When digital scaling occurs, the electronic device may not expand the display, but may instead only enlarge the image displayed on the screen.

[0159] According to various embodiments, in steps 1230, 1240, and 1250, the electronic device can change the camera used for image capture according to the scaling factor. For example, if the maximum scaling factor is 50.0x, a first camera can be used for image capture in the range of 1.0x to 10.0x, a second camera can be used for image capture in the range of 10.0x to 30.0x, and a third camera can be used for image capture in the range of 30.0x to 50.0x. In this case, if the scaling factor determined by touch input is 35.0x, in step 1231, the first camera can be used for image capture up to 10.0x, the second camera can be used in the range of 10.0x to 30.0x, and the third camera can be used in the range of 30.0x to 35.0x. According to embodiments, the user can change the screen magnification ratio according to the number of cameras.

[0160] According to various embodiments, the electronic device can receive information about user touch input from a touch sensor. According to embodiments, the electronic device can determine a zoom level by utilizing the information about the touch input. The zoom level can mean how much the preview of the subject is magnified. For example, if the maximum zoom level of the electronic device is 50.0x, the electronic device can be configured to increase the zoom level by 5.0x whenever the distance between two touch points increases by 1 cm via a pinch-to-zoom gesture. If the distance between the touch points increases by 7 cm via a first touch input, the zoom level can be determined to be 35.0x, and if the distance between the touch points decreases by 2 cm via a second touch input, the zoom level can be determined to be 25.0x.

[0161] According to another embodiment, touch input may include operations related to a zoom guide bar. Specifically, the zoom guide bar may include at least one of a bar in the form of a strip, scales, a zoom ratio graph, and an indicator line. If the zoom ratio of the display's maximum extended length is less than the maximum zoom ratio, the zoom guide bar may additionally include a graphical object indicating the zoom ratio of the display's maximum extended length. The scales may be displayed along with the bar and may be displayed at a distance so that the user can easily know the zoom ratio at the corresponding position. The zoom ratio graph may be displayed on one side of the bar and may display graphical information about the zoom ratio corresponding to that position. According to an embodiment, if the zoom guide bar is set to be horizontally long, the zoom ratio may be configured to increase from left to right. However, the embodiment is not limited to this, and the zoom ratio may increase from right to left, or if the bar is set to be vertically long, the zoom ratio may be configured to increase from bottom to top. The indicator line may be located inside the bar and may represent information about the current zoom ratio. The user can adjust the zoom ratio by touching and dragging the indicator line. For example, if a user wants to change the current zoom level from 10.0x to 25.0x, the user can touch the indicator line at the 10.0x position and drag the indicator line to the position corresponding to 25.0x, referring to the zoom level. After determining the zoom level, the electronic device can enlarge the image to the same zoom level, calculate expansion information about the length the display should expand to based on the zoom level, and send the calculated expansion information to the motor module 740.

[0162] According to various embodiments, the electronic device can also perform the operation of reducing the display based on the user's pinch-to-zoom gesture or operation on the zoom guide bar. For example, in the case of moving the pinch-to-zoom gesture to the left (or right) or the indicator line of the zoom guide bar, the reduction zoom ratio can be calculated, and the display can be reduced by transmitting extended information based on the zoom ratio calculation to the motor module. The following description includes cases where the image and display are reduced by receiving pinch-to-zoom or operation on the zoom guide bar.

[0163] Figure 12bThis is a flowchart illustrating a method for enlarging an image and expanding a display based on a calculated zoom level. According to various embodiments, in step 1271, the electronic device can enlarge or shrink the image to the same determined zoom level. That is, the electronic device can enlarge or shrink the image received by camera 730 and display that image on the display. In this case, the image can be enlarged around the center point of the line connecting the two touch points or the center of the display screen. For example, if the user performs a pinch-to-zoom operation, the image can be enlarged around the center point of the line connecting the two touch points. If the user operates a zoom guide bar, a touch point is provided, and the image can be enlarged based on the center of the display screen. The user can view a wider screen horizontally (or vertically) through the enlarged display.

[0164] According to various embodiments, in step 1273, the electronic device may send expansion information calculated based on the scaling factor to the motor module 740. The expansion information may include information about the length of the display that should be expanded. The length of the display to be expanded may be determined proportionally to the maximum expansion length. For example, if the maximum expansion length of the display is 10 cm and the maximum scaling factor is 50.0x, and the scaling factor calculated via the first touch input is 35.0x, then the display can be expanded by 7 cm, and the expansion information may include a command to expand the display by 7 cm. The motor module 740 can expand the display by 7 cm by receiving the expansion information. Subsequently, if the scaling factor calculated via the second touch input is 25.0x, the display can be reduced by 2 cm, and the expansion information may include a command to reduce the display by 2 cm. The motor module can reduce the display by 2 cm based on the received expansion information.

[0165] According to various embodiments, at least a portion of the flexible portion extended by the display can be an extended area of ​​the display screen. In step 1275, the electronic device can display an enlarged image in the extended area based on user touch input.

[0166] According to various embodiments, the electronic device can display an animation simultaneously with an image displayed in the extended area. According to one embodiment, the electronic device can operate such that during the expansion of the display via the motor module, only a black screen is displayed in the extended area, and after the expansion is complete, the electronic device immediately displays the enlarged image across the entire area of ​​the display, including the extended area. For example, if the magnification is increased from 10.0x to 20.0x via user touch input, the extended area may increase when the flexible portion of the motor module is withdrawn. During withdrawal, only a black screen is displayed in the extended area, and no image may appear. Furthermore, after the expansion is complete, the image is expanded to the same magnification as the increased magnification, and the expanded image is displayed on the display.

[0167] According to another embodiment, the electronic device can first complete and extract the screen from the extended area to be extracted. For example, in the case of extracting a flexible portion based on user touch input, the electronic device can enlarge the screen based on a predetermined scaling factor, and can also enlarge the image simultaneously while extracting the flexible portion. That is, the expansion of the display and the enlargement of the image can occur simultaneously.

[0168] According to various embodiments, the electronic device can adjust the center position of an existing display screen that the user has already viewed when the flexible portion is pulled out. For example, if the display extends to the right, the electronic device can move the display screen to the right and position the display screen such that the center of the display and the center of the screen coincide with each other. According to embodiments, in this case, extended areas can be generated on both side surfaces of the existing display screen.

[0169] According to various embodiments, the electronic device can extend the display in only one direction, or it can extend the display in both lateral directions. For example, if the motor module appears on both side surfaces of the display, the display can extend to the right and left simultaneously.

[0170] According to various embodiments, if a user expands the display by applying physical force to it, the same effect as pinch-to-zoom can occur. For example, if the display is expanded by applying force, the electronics can calculate a scaling factor based on the expanded length, enlarge the image based on the calculated scaling factor, and move the zoom guide bar's indicator line. Even in the case of shrinking the display, the opposite effect occurs in the same way, and therefore will not be explained in more detail. All that is described below includes expanding the image by physically expanding the display.

[0171] According to various embodiments, the display can be expanded based on the user's pinch-to-zoom gestures. A pinch-to-zoom gesture can mean touching and dragging two touch points to increase or decrease the distance between the two touch points.

[0172] According to various embodiments, if a user performs a pinch-to-zoom gesture, the image is enlarged. If a touch sensor detects the user's touch input, the electronic device can calculate the zoom level by analyzing information received from the touch sensor. The electronic device can then calculate the extended length of the display based on the calculated zoom level. The electronic device can send extension information, including the calculated extended length, to a motor module, and the motor module can extend the display based on the received extension information. According to embodiments, the electronic device can provide a wider screen by simultaneously enlarging the image and extending the display. According to another embodiment, the indicator line of a zoom guide bar located on one side of the display screen can move together with different zoom levels.

[0173] For example, if the distance between two touch points increases by 1 cm, the zoom level increases by 2.0x. The first zoom level display has a zoom level of 1.0x without any expansion, and in this case, if the user performs a 4 cm pinch-to-zoom, the zoom level increases to 9.0x. As a result, the first zoom level is expanded to the second zoom level, the first zoom level display is expanded to the second zoom level display, and the zoom guide bar indicator moves to the right, indicating 9.0x. Similarly, if the user performs a 6 cm pinch-to-zoom, the zoom level increases to 21.0x, and the second zoom level and the second zoom level display are expanded to the third zoom level and the third zoom level display, respectively. At 21.0x, which is the maximum zoom level, the zoom guide bar indicator will continue to move to the right.

[0174] According to various embodiments, the electronic device can determine the scaling factor by receiving operations on the scaling guide bar, thereby enlarging the image and expanding the display. Since the scaling factor is directly determined by the user through the scaling guide bar operation, the electronic device does not need to calculate the scaling factor separately.

[0175] According to various embodiments, an electronic device can capture an image of a subject by using multiple cameras that capture images of the subject at different zoom levels. The respective cameras can have different viewing angles. For example, with the electronic device's maximum zoom level at 50.0x, a first camera with the widest viewing angle can handle zoom levels from 1.0x to 10.0x, a second camera can handle zoom levels from 10.0x to 30.0x, and a third camera with the narrowest viewing angle can handle zoom levels from 30.0x to 50.0x. According to embodiments, flickering may occur on the display screen when the cameras are switched.

[0176] According to various embodiments, if the scaling factor increases based on user touch input, the display also expands to match the corresponding scaling factor. For example, when the user performs a capture using the first camera, it may expand by only 1 / 5 of the maximum expansion length; when capturing with the second camera, it may expand by only 3 / 5 of the maximum expansion length; and when capturing with the third camera, it may expand by the maximum expansion length. Other embodiments are the same as those described above and will therefore be omitted.

[0177] According to various embodiments, a user can enlarge an image by applying physical force to the display to expand the display. According to embodiments, the electronic device can enlarge or reduce the image by calculating a scaling factor based on the extended length of the display. For example, when displaying a first-magnification subject on a first-magnification display, the user can enlarge the image by pulling the display to either side. If the maximum scaling factor is 50.0x and the maximum extended length of the display is 10 cm, the user can extend the first-magnification display (e.g., 4 cm) to a second-magnification display, and in this case, the electronic device can calculate the scaling factor and enlarge the first-magnification subject (e.g., 1.0x) to the second-magnification subject (e.g., 20.0x). If the user further extends (e.g., 10 cm) to a third-magnification display, the image can also be enlarged to the third-magnification subject (e.g., 50.0x).

[0178] According to an embodiment, the display screen may include at least one zoom guide bar. The zoom guide bar may include at least one of the following: a bar in the form of a scale, an indicator line, and a zoom level graph. The indicator line is a configuration that displays the current zoom level, and if the user changes the zoom level by enlarging the display, the indicator line may move accordingly. For example, when capturing an image of a subject at a first zoom level, the indicator line is located at the left end of the zoom guide bar, but when performing image capture at a second or third zoom level, the indicator line may gradually move to the right end of the zoom guide bar.

[0179] According to various embodiments, although not shown in the figures, if the display is physically reduced, the electronic device can operate in the opposite manner to the above. That is, the image can be reduced, and the zoom guide bar's indicator line can be moved to the left.

[0180] According to various embodiments, the electronic device can expand the display horizontally and vertically. When a user performs a pinch-to-zoom gesture or operates a zoom guide bar, the electronic device can expand the display vertically while simultaneously enlarging the image based on touch input.

[0181] For example, an electronic device can receive an image of a subject from a camera and display the subject at a first magnification on a first magnification display. The first magnification subject displayed on the first magnification display can be enlarged to a second magnification subject via user touch input, including at least one pinch-to-zoom gesture and a zoom guide bar operation. As the image is enlarged, the first magnification display can also be expanded to a second magnification display via a motor module. In the case of shrinking the image to a third magnification subject via a pinch-to-zoom gesture or a zoom guide bar operation, the second magnification display is shrunk to the third magnification display via the motor module.

[0182] According to various embodiments, physically pushing the display upwards can enlarge the image, similar to performing a pinch-to-zoom gesture. Conversely, pulling the display downwards can shrink the image, similar to performing a pinch-to-zoom gesture.
