In some embodiments, the electronic device (101) may omit at least one of these components (e.g., the connection 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 one component (e.g., the display module (160)).

[0027] The processor (120) may, for example, execute software (e.g., a program (140)) to control at least one other component (e.g., a hardware or software component) of the electronic device (101) connected to the processor (120) and perform various data processing or calculations.

For example, if the electronic device (101) includes a main processor (121) and a secondary processor (123), the secondary processor (123) may be configured to use less power than the main processor (121) or to be specialized for a specified function. The secondary processor (123) may be implemented separately from the main processor (121) or as a part thereof.

[0028] The auxiliary processor (123) may control at least a portion of functions or states associated with at least one component (e.g., a display module (160), a sensor module (176), or a communication module (190)) of the electronic device (101), for example, on behalf of the main processor (121) while the main processor (121) is in an inactive (e.g., sleep) state, or together with the main processor (121) while the main processor (121) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (123) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (180) or a communication module (190)). In one embodiment, the auxiliary processor (123) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, in the electronic device (101) itself where artificial intelligence is performed, or can be performed through a separate server (e.g., server (108)). The learning algorithm can include, for example, supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning, but is not limited to the examples described above.

In addition to, or alternatively to, a hardware structure, an artificial intelligence model may include a software structure.

[0029] The memory (130) can store various data used by at least one component (e.g., processor (120) or sensor module (176)) of the electronic device (101).

The speaker can be used for general purposes, such as multimedia playback or recording playback. The receiver can be used to receive incoming calls. In one embodiment, the receiver can be implemented separately from the speaker or as part of the speaker.

[0033] The display module (160) can visually provide information to an external party (e.g., a user) of the electronic device (101). The display module (160) may include, for example, a display, a holographic device, or a projector and a control circuit for controlling the device. In one embodiment, the display module (160) may include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the intensity of a force generated by the touch.

[0034] The audio module (170) can convert sound into an electrical signal, or vice versa, convert an electrical signal into sound. According to one embodiment, the audio module (170) can acquire sound through the input module (150), output sound through the sound output module (155), or an external electronic device (e.g., electronic device (102)) (e.g., speaker or headphone) directly or wirelessly connected to the electronic device (101).

[0035] The sensor module (176) can detect the operating status (e.g., power or temperature) of the electronic device (101) or the external environmental status (e.g., user status) and generate an electrical signal or data value corresponding to the detected status. According to one embodiment, the sensor module (176) can include, for example, a gesture sensor, a gyro sensor, a barometric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an IR (infrared) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

[0036] The interface (177) may support one or more designated protocols that may be used to directly or wirelessly connect the electronic device (101) with an external electronic device (e.g., the electronic device (102)). In one embodiment, the interface (177) may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, or an audio interface.

[0037] The connection terminal (178) may include a connector through which the electronic device (101) may be physically connected to an external electronic device (e.g., electronic device (102)). According to one embodiment, the connection 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).

[0038] The haptic module (179) can convert electrical signals into mechanical stimuli (e.g., vibration or movement) or electrical stimuli that a user can perceive through tactile or kinesthetic sensations. In one embodiment, the haptic module (179) can include, for example, a motor, a piezoelectric element, or an electrical stimulation device.

[0039] The camera module (180) can capture still images and videos. According to one embodiment, the camera module (180) may include one or more lenses, image sensors, image signal processors, or flashes.

[0040] The power management module (188) can manage power supplied to the electronic device (101). According to one embodiment, the power management module (188) can be implemented, for example, as at least a part of a power management integrated circuit (PMIC).

[0041] A battery (189) may power at least one component of the electronic device (101). In one embodiment, the battery (189) may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0042] The communication module (190) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (101) and an external electronic device (e.g., electronic device (102), electronic device (104), or server (108)), and the performance of communication through the established communication channel. The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0043] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module (192) can support various requirements specified in the electronic device (101), an external electronic device (e.g., the electronic device (104)), or a network system (e.g., the second network (199)). According to one embodiment, the wireless communication module (192) may support a peak data rate (e.g., 20 Gbps or more) for eMBB realization, a loss coverage (e.g., 164 dB or less) for mMTC realization, or a U-plane latency (e.g., 0.5 ms or less for downlink (DL) and uplink (UL), or 1 ms or less for round trip) for URLLC realization.

[0044] The antenna module (197) can transmit or receive signals or power to or from an external device (e.g., an external electronic device). In one embodiment, the antenna module (197) may include an antenna including a radiator formed of a conductor or a 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 this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (198) or the second network (199), may be selected from the plurality of antennas by, for example, the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device through the selected at least one antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (197).

[0045] In one embodiment, the antenna module (197) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high-frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high-frequency band.

[0046] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0047] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (101) may provide an ultra-low latency service by using distributed computing or mobile edge computing, for example. In another embodiment, the external electronic device (104) may include an Internet of Things (IoT) device. The server (108) may be an intelligent server utilizing machine learning and / or a neural network. According to one embodiment, the external electronic device (104) or the server (108) may be included in the second network (199).The electronic device (101) can be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology and IoT-related technology.

[0048] FIG. 2 is a simplified block diagram of an electronic device, an external case, and an external electronic device according to one embodiment.

[0049] Referring to FIG. 2, an electronic device (101) according to one embodiment may include a processor (120), a first housing (e.g., the first housing (310) of FIG. 3A), a second housing (e.g., the second housing (320) of FIG. 3A), a display (230), a wireless communication circuit (192), a sensor (210), a memory (130), and / or a battery (189). Depending on the embodiment, the second wireless communication circuit (222), the second sensor (212), and / or the third sensor (213) may be omitted. Although not illustrated, the electronic device (101) may include various components in addition to the components described above.

[0050] For example, the electronic device (101) may include a first housing (e.g., the first housing (310) of FIG. 3A) and a second housing (e.g., the second housing (320) of FIG. 3A) that are rotatably coupled to each other. For example, the second housing (320) may be rotatably coupled to the first housing (310) about a folding axis (e.g., the folding axis (337) of FIG. 3A). The first housing (310) and the second housing (320) will be described later with reference to FIGS. 3A and 3B.

[0051] For example, the processor (120) may be operatively connected to the cover display (231), the wireless communication circuit (192), the sensor (210), and / or the memory (130). The processor (120) being operatively connected to the memory (130), the cover display (231), the wireless communication circuit (192), and / or the sensor (210) may mean that the processor (120) is directly connected to the components or connected to the components through another component. For example, the processor (120) may be configured to control the cover display (231), the wireless communication circuit (192), the sensor (210), and / or the memory (130). For example, the processor (120) may include a hardware component for processing data based on one or more instructions. Hardware components for processing data may include, for example, an arithmetic and logic unit (ALU), a field programmable gate array (FPGA), and / or a central processing unit (CPU). The processor (120) may cause the electronic device (101) to operate by executing instructions stored in the memory (130). The operation of the processor (120) will be described below.

[0052] For example, the memory (130) (e.g., the memory (130) of FIG. 1) may be a volatile memory unit or units. For example, the memory (130) may be a non-volatile memory unit or units. For example, the memory (130) may be another form of computer-readable media, such as a magnetic or optical disk. For example, the memory (130) may store data acquired based on an operation performed by the processor (120) (e.g., an algorithm execution operation). For example, the memory (130) may be used to store one or more programs (e.g., the accessory manager (710) and / or the screen change manager (720) of FIG. 7). The one or more programs may include instructions for performing a defined operation when executed by the processor (120) of the electronic device (101). When the instructions are executed by the processor (120), an operation of the electronic device (101) may be caused.

[0053] For example, within the memory (130), one or more instructions representing operations and / or actions to be performed by the processor (120) on data may be stored. A set of one or more instructions may be referred to as firmware, an operating system, a process, a routine, a sub-routine, and / or an application. For example, the electronic device (101) and / or the processor (120) may perform at least one of the operations of the electronic device (101) described below when a set of a plurality of instructions distributed in the form of an operating system, firmware, driver, and / or application is executed. Hereinafter, the fact that an application is installed in an electronic device (101) may mean that one or more instructions provided in the form of an application are stored in the memory (130) of the electronic device (101), and that the one or more applications are stored in a format executable by the processor (120) of the electronic device (101) (e.g., a file having an extension specified by the operating system of the electronic device (101)).

[0054] For example, the display (230) may include a flexible display (232) and a cover display (231). For example, the flexible display (232) may be visible from the outside of the electronic device (101) in an unfolded state and / or an intermediate state. For example, the flexible display (232) may not be visible from the outside of the electronic device (101) in a folded state by being covered by the first housing (310) and the second housing (320). The flexible display (232) may be referred to as a main display.

[0055] For example, the cover display (231) can be externally visible independently of the state of the electronic device (101) (e.g., folded state, unfolded state, and / or intermediate state). For example, the cover display (231) can be disposed on the outer surface of the first housing (310). For example, the cover display (231) can be disposed on the second surface (e.g., the second surface (312) of FIG. 3B) of the first housing (310), thereby being externally visible at all times, independently of the state of the electronic device (101). The cover display (231) can be referred to as an external display or a sub-display. An example of the cover display (231) will be illustrated through FIG. 3B.

[0056] For example, the electronic device (101) may include a wireless communication circuit (192) to be used for communication with the external case (401) and / or an external electronic device (402). For example, the communication circuit may be used for various radio access technologies (RATs). According to one embodiment, the wireless communication circuit (192) may include a first wireless communication circuit (221) and / or a second wireless communication circuit (222). For example, the first wireless communication circuit (221) may be used for performing near field communication (NFC). For example, the second wireless communication circuit (222) may be used for performing cellular communication and / or wireless LAN communication with the external electronic device (402).

[0057] For example, the sensor (210) may generate electrical information that may be processed by the processor (120) and / or the memory (130) from non-electronic information related to the electronic device (101). The electrical information generated by the sensor (210) may be stored in the memory (130), processed by the processor (120), and / or transmitted to another electronic device distinct from the electronic device (101). For example, there may be one or more sensors (210).

[0058] For example, the sensor (210) may include a first sensor (211), a second sensor (212), and / or a third sensor (213). For example, the first sensor (211) may be used to identify a connection of the outer case. For example, the second sensor (212) may be used to identify a user input (e.g., a touch input) provided to the cover display. For example, the third sensor (213) may be used to identify a state of the electronic device (e.g., a folded state, an unfolded state, and / or an intermediate state). The functions of each of the first sensor (211), the second sensor (212), and / or the third sensor (213) will be described below.

[0059] For example, the battery (189) may be configured to store power and provide the stored power for various operations of the electronic device (101). For example, the battery (189) may include a rechargeable secondary battery. For example, the processor (120) may estimate the state of charge (SOC) of the battery (189), which represents the remaining capacity relative to the total capacity of the battery (189).

[0060] For example, the outer case (401) may be coupled to the outer side of the first housing (310) and the second housing (320). The outer case (401) may protect the electronic device (101) by at least partially covering the outer surface of the first housing (310) and the outer surface of the second housing (320). For example, the outer case (401) may include a frame (e.g., the frame (410) of FIG. 4A) and an external object (420). For example, the external object (420) may include, but is not limited to, a card and / or a palette. For example, the external object (420) may include a detection object (421) and a chip (e.g., an NFC chip). For example, the detection object (421) may include a magnet.

[0061] For example, when the detection object (421) is positioned within a specified distance from the electronic device (101), the processor (120) may identify, through the first sensor (211), that the detection object (421) is within the specified distance. For example, the processor (120) may be configured to identify that the external object (420) is coupled to the second housing (320) based on identifying, through the first sensor (211), that the detection object (421) is within a specified transaction. For example, the chip (422) may provide the first wireless communication circuit (221) with an identifier assigned to the external case (401) and data related to the external case (401) using NFC. The first wireless communication circuit (221) may receive the identifier and the data through the first antenna (223), and provide the received identifier and the data to the processor (120).

[0062] According to one embodiment, the electronic device (101) may display content to be displayed through the cover display (231) based on the data. For example, the content may include first content and second content. For example, the first content may be referenced as any of the content pre-stored in the memory (130). For example, the second content may be referenced as content that can be downloaded from an external electronic device (402).

[0063] Below, with reference to the drawings, an operation of displaying content on a cover display (231) is described.

[0064] FIG. 3A illustrates an unfolded state of an electronic device according to one embodiment. FIG. 3B illustrates intermediate states and a folded state of an electronic device according to one embodiment.

[0065] Referring to FIGS. 3A and 3B, the electronic device (101) may be an example of the electronic device (101) of FIG. 1. For example, the electronic device (101) may include a first housing (310) and a second housing (320).

[0066] For example, the first housing (310) and the second housing (320) may be rotatably coupled with respect to the folding axis (337). For example, the second housing (320) may be rotatably coupled to the first housing (310). For example, the electronic device (101) may include a hinge structure (e.g., the hinge structure (365) of FIG. 3B) for rotatably connecting the first housing (310) and the second housing (320). For example, the hinge structure (365) may enable the electronic device (101) to change from an unfolding state to a folding state. For example, the hinge structure (250) may enable the electronic device (101) to change from a folding state to an unfolding state. For example, the hinge structure (250) may maintain the electronic device (101) in an intermediate state between the unfolding state and the folding state. The intermediate state may be referred to as a state between the folding state and the unfolding state.

[0067] For example, the first housing (310) may include a first surface (311) and a second surface (312) opposite the first surface (311). For example, the second housing (320) may include a third surface (321) and a fourth surface (322) opposite the third surface (321). For example, the first surface (311) and the third surface (321) may be referred to as a front surface of the first housing (310) and a front surface of the second housing (320). For example, the second surface (312) and the fourth surface (322) may be referred to as a rear surface of the first housing (310) and a rear surface of the second housing (320).

[0068] For example, the electronic device (101) may include a flexible display (232). The flexible display (232) may be disposed on a first housing (310) (e.g., a first surface (311)) and a second housing (320) (e.g., a third surface (321)). For example, the flexible display (232) may include a first display area (232a), a second display area (232b), and a third display area (232c). The first display area (232a) may be disposed on the first surface (311) of the first housing (310). The second display area (232b) may be disposed on the third surface (321) of the second housing (320). The third display area (232c) may be positioned between the first display area (232a) and the second display area (232b). The third display area (232c) may be positioned along the folding axis (337).

[0069] For example, the electronic device (101) can provide an unfolding state in which the first housing (310) and the second housing (320) are fully folded out by the hinge structure (365). For example, referring to FIG. 3A, the electronic device (101) can be in the unfolding state. For example, the unfolding state can mean a state in which a first direction (391) toward which the first surface (311) faces corresponds to a second direction (392) toward which the third surface (321) faces. For example, within the state (300), the first direction (391) can be parallel to the second direction (392). For example, within the state (300), the first direction (391) can be identical to the second direction (392). The first direction (391) may correspond to the direction in which the first display area (232a) faces, and the second direction (392) may correspond to the direction in which the second display area (232b) faces.

[0070] In the unfolded state, the first side (311) can form substantially the same plane as the third side (321). For example, the angle (305-1) between the first side (311) and the third side (321) in the unfolded state can be 180 degrees. For example, the unfolded state can mean a state in which substantially the entire display area of ​​the flexible display (232) can be provided on a single plane. For example, the unfolded state can mean a state in which the first display area (232a), the second display area (232b), and the third display area (232c) can all be provided on a single plane. For example, the unfolded state can be referred to as an outspread state or outspreading state. Below, different states of the electronic device (101) based on angles (305-2, 205-3, 205-4) are described.

[0071] Referring to FIG. 3b, an electronic device (101) according to one embodiment can provide a folding state in which the first housing (310) and the second housing (320) are folded in by a hinge structure (365).

[0072] For example, the electronic device (101) may be in an intermediate state between an unfolded state and a folded state. For example, states (300A) and (300B) may be referred to as intermediate states. For example, state (300C) may be referred to as a folded state. Within the intermediate state and the folded state, the first direction (391) toward which the first face (311) faces may be different from the second direction (392) toward which the third face (321) faces. For example, within the intermediate state and the folded state, the third display area (232c) may be at least partially bent.

[0073] For example, within state (300A), the angle between the first direction (391) and the second direction (392) may be about 45 degrees. For example, within state (300B), the angle between the first direction (391) and the second direction (392) may be about 150 degrees. For example, in the folded state (300C), the angle between the first direction (391) and the second direction (392) may be substantially 180 degrees. For example, in state (300A), the angle (305-2) between the first side (311) and the third side (321) may be 135 degrees. For example, in state (300B), the angle (305-3) between the first side (311) and the third side (321) may be 30 degrees. For example, in state (300C), the angle (305-4) between the first side (311) and the third side (321) may be substantially 0 degrees. For example, the folded state may be referred to as a folded state. For example, the folded state may provide a state (300C) in which the first direction (391) is substantially opposite to the second direction (392). For example, state (300C) may mean a state in which the flexible display (232) is covered within the field of view of a user looking at the electronic device (101). However, the present invention is not limited thereto.

[0074] An electronic device (101) according to one embodiment can display a screen through a cover display (231). The cover display (231) can always be viewed from the outside, independently of the state of the electronic device (101). An external case (e.g., an external case (401) of FIG. 4A) can at least partially cover the outer surface of the first housing (310) and the outer surface of the second housing (320). For example, the external case (401) can at least partially cover the second side (312) and the fourth side (322). The electronic device (101) can display a screen including content using the cover display (231) based on an external object (e.g., an external object (420) of FIG. 4A) located within a specified distance from the electronic device (101). For example, the external object (420) can be fixed through a frame (410) coupled to the electronic device (101).

[0075] FIG. 4A illustrates an electronic device and an external case according to one embodiment. FIG. 4B illustrates an electronic device and an external object according to one embodiment.

[0076] Referring to FIG. 4a, an electronic device (101) according to one embodiment may include a first housing (310) and a second housing (320).

[0077] For example, the outer case (401) may include a frame (410) forming an exterior. For example, the frame (410) may include a first frame part (411) and a second frame part (412). For example, the first frame part (411) may be coupled to an outer surface of the first housing (310) to cover at least a portion of the first housing (310). For example, so that the cover display (231) can be viewed from the outside, the first frame part (411) may include an opening (411a) corresponding to the cover display (231). Through the opening (411a), the cover display (231) may be exposed to the outside of the outer case (401). The size of the first frame part (411) may correspond to the size of the first housing (310). For example, the second frame part (412) may cover at least a portion of the second housing (320) by being coupled to the outer surface of the second housing (320). The size of the second frame part (412) may correspond to the size of the second housing (320).

[0078] The outer case (401) may include an external object (420). For example, the external object (420) may be positioned between the second housing (320) and the frame (410) by being coupled to the frame (410). For example, since the first frame part (411) is coupled to the outer surface of the first housing (310) where the cover display (231) is positioned, the external object (420) may be inserted into the second frame part (412). The second frame part (412) may be coupled to the outer surface of the second housing (320) while the external object (420) is inserted therein. For example, the second frame part (412) may include a slot into which the external object (420) may be inserted. For example, the slot may include a guide portion through which the external object (420) may slide and be fixed to the second frame part (412). A portion of the edge of the external object (420) can be joined to the guide portion in a force-fit manner.

[0079] Referring to FIG. 4B, the external object (420) may include a sensing object (421) and a chip (422). The sensing object (421) and the chip (422) may be placed at designated locations within the external object (420). For example, the chip (422) may include various information. For example, the chip (422) may include an identifier of the external case (401) and data related to the external case (401).

[0080] For example, the electronic device (101) may include a first sensor (211) for identifying that a detection object (421) is located within a specified distance, and a first antenna (223) for receiving a wireless signal from a chip (422). For example, the location of the first sensor (211) may correspond to the location of the detection object (421), and the location of the first antenna (223) may correspond to the location of the chip (422). For example, when an external object (420) is inserted into the frame (410), the detection object (421) may at least partially overlap with the first sensor (211), and the chip (422) may at least partially overlap with the first antenna (223). For example, the first antenna (223) may be disposed within a second housing (e.g., the second housing (320) of FIG. 3A).

[0081] For example, the outer case (401) may be substantially transparent. For example, one side of the outer object (420) may include an image. When the outer object (420) is placed within the second frame part (412) with the one side facing the outside of the electronic device (101), the image within the one side may be recognized through the substantially transparent second frame part (e.g., the second frame part (412) of FIG. 4A). The image included within the one side may provide various visual effects to the user. For example, the user may select the outer object (420) including an image that suits the user's taste and insert it within the second frame part (412), and thus the outer case (401) may provide an enhanced user experience.

[0082] For example, a processor (e.g., processor (120) of FIG. 2) may identify content based on data acquired from a chip (422) of an external object (420) through a first antenna (223). The processor (120) may be configured to control the cover display (231) so that the identified content is displayed through the cover display (231). For example, the content may include content corresponding to an image included in one surface of the external object (420). Through the cover display (231), the content and the image included in one surface of the external object (420) may provide a visual effect provided to the outside of the electronic device (101). The electronic device (101) according to one embodiment may provide an enhanced user experience through the visual effect.

[0083] FIG. 5 is a flowchart illustrating an operation of displaying content through a cover display of an electronic device according to one embodiment.

[0084] The operations described in FIG. 5 may be operations caused by an electronic device (e.g., an electronic device (101) of FIG. 2) when instructions stored in a memory (e.g., a memory (130) of FIG. 2) are executed by a processor (e.g., a processor (120) of FIG. 2).

[0085] Referring to FIG. 5, in operation 501, a processor (e.g., processor (120) of FIG. 2) can identify a coupling between an outer case (e.g., outer case (401) of FIG. 2) and a second housing (e.g., second housing (320) of FIG. 3A) through a first sensor (e.g., first sensor (211) of FIG. 2).

[0086] For example, when the outer case (401) is positioned within a specified distance from the electronic device (e.g., the electronic device (101) of FIG. 2), the first sensor (211) can provide an electric signal to the processor (120) based on a detection object (e.g., a detection object (421) of FIG. 4B) positioned within a frame (e.g., a frame (410) of FIG. 4B). For example, the detection object (421) can include a magnet, and the first sensor (211) can include a Hall sensor that provides an electric signal representing a change in a magnetic field caused by the magnet. For example, when a second frame part (e.g., a second frame part (412) of FIG. 4A) into which the external object (420) is inserted is coupled to the outer surface of the second housing (320), the Hall sensor can provide an electric signal to the processor (120) based on a change in a magnetic field caused by a magnet positioned within a specified distance. The processor (120) may be configured to identify that the outer case (401) is coupled to the second housing (320) based on an electrical signal provided from the hall sensor.

[0087] In operation 503, the processor (120) may establish a communication channel with the external case (401) through a first antenna (e.g., the first antenna (223) of FIG. 2) and a first wireless communication circuit (e.g., the first wireless communication circuit (221) of FIG. 2).

[0088] For example, the first antenna (223) may include an NFC antenna used for short-range wireless communication. For example, the processor (120) may activate the first antenna (223) to establish a communication channel based on identifying the engagement of the outer case (401). For example, when a chip (e.g., chip (422) of FIG. 4B) located within the frame (410) is located within a specified distance (e.g., about 10 cm) from the activated first antenna (223), an NFC communication channel may be established to transmit information contained within the chip (422) (e.g., an identifier assigned to the outer case (401) and data related to content).

[0089] In operation 505, the processor (120) can obtain an identifier assigned to the external case (401) and data related to the external case (401) through an established communication channel.

[0090] For example, the first wireless communication circuit (221) may include an NFC communication circuit. The first wireless communication circuit (221) may receive data related to an identifier and content assigned to the outer case (401) from a chip (422) included in the frame (410) through an established communication channel.

[0091] For example, an identifier assigned to an external case (401) can be used to distinguish the type of the external case (401). For example, the identifier can be used for authentication of the external case (401).

[0092] In operation 507, the processor (120) may identify content to be displayed through a cover display (e.g., cover display (231) of FIG. 2).

[0093] For example, data related to content may include data related to content to be displayed through the cover display (231). For example, the content may include first content and second content. The first content will be described with reference to FIGS. 9A and 9B. The second content will be described with reference to FIGS. 9A and 9C. The data related to content may include information regarding content to be displayed on the cover display (231). The processor (120) may identify content to be displayed through the cover display (231) based on the acquired data. For example, the processor (120) may identify whether information regarding content included in the acquired data represents the first content or the second content.

[0094] In operation 509, the processor (120) may control the cover display (231) to display content through the cover display (231). The cover display (231) may be configured to display content. When content is displayed on the cover display (231), the content may be visible from outside the electronic device (101). The user may select an external object (420) to display content according to his / her preference and insert it into the frame (410). The user may express his / her individuality through the content displayed on the cover display (231). The electronic device (101) according to one embodiment may provide an enhanced user experience.

[0095] FIG. 6A illustrates a process of displaying content on a cover display. FIG. 6B illustrates an unfolded state of an electronic device according to one embodiment.

[0096] Referring to FIG. 6A, an external object (420) can be inserted into a frame (410) coupled to an electronic device (101). State 601 of FIG. 6A represents the electronic device (101) with the external case (401) coupled to the electronic device (101) before the external object (420) is inserted. State 603 of FIG. 6A represents the electronic device (101) before displaying content through the cover display (231) after the external object (420) is inserted. State 605 of FIG. 6A represents the electronic device (101) displaying content through the cover display (231).

[0097] Referring to FIG. 6A, in state 601, the electronic device (101) may be coupled with the external case (401). An external object (420) may be inserted into a frame (410) coupled to the electronic device (101). When the external object (420) is inserted into the frame (410), a first sensor (e.g., the first sensor (211) of FIG. 4B) may provide an electrical signal to a processor (e.g., the processor (120) of FIG. 2) based on a detection object (e.g., the detection object (421) of FIG. 4B) included in the external object (420). The processor (120) may identify the coupling of the external case (401) by identifying the insertion of the external object (420) through the first sensor (211). Although FIG. 6A illustrates the external object (420) being inserted into the frame (410), the present invention is not limited thereto. For example, the outer case (401) may be coupled to the electronic device (101) while being coupled to an external object (420).

[0098] For example, in state 601, before an external object (420) is inserted into the frame (410), the processor (120) may display a basic screen (602) through the cover display (231). For example, the basic screen (602) may refer to a screen that is provided by default through the cover display (231) in the electronic device (101). For example, the basic screen (602) may refer to a screen that does not include content.

[0099] At state 603, the processor (120) can identify that the outer case (401) is coupled. The processor (120) can establish a communication channel through a first antenna (e.g., the first antenna (223) of FIG. 4B) and a first wireless communication circuit (e.g., the first wireless communication circuit (221) of FIG. 2). Through the established communication channel, the processor (120) can obtain data related to an identifier and content assigned to the outer case (401) included in a chip (e.g., the chip (422) of FIG. 4B). For example, the processor (120) can obtain data related to an identifier and content assigned to the outer case (401) through NFC.

[0100] For example, the processor (120) may display a visual object (e.g., a user interface) (604) through the cover display (231). The visual object (604) may be displayed in an overlapping manner on the main screen (602). The visual object (604) may include text indicating that the external case (401) has been coupled and / or text indicating that content may be displayed on the cover display (231). However, the present invention is not limited thereto. The user may recognize that the electronic device (101) has identified the coupling of the external object (420) through the text and recognize that content may be displayed. As another example, the visual object may include text indicating that information related to the content is being acquired. Another example will be exemplified through FIG. 9D.

[0101] In state 605, the processor (120) can display content through the cover display (231). For example, the processor (120) can control the cover display (231) so that the content is identified through the cover display (231). For example, the processor (120) can change the screen displayed through the cover display (231) from the basic screen (602) to the screen (606) including the content based on data related to the acquired content. For example, the processor (120) can maintain the display of the content based on the state in which the external case (401) remains coupled to the electronic device (101).

[0102] Referring to FIG. 6B, the content displayed through the cover display (231) may be related to an image (423) included in one side of the external object (420). For example, the content may include a dynamic image (e.g., a video, a hologram, an animation, and / or a flash), and the image (423) included in one side of the external object (420) may include a static image. The dynamic image included in the content may be related to the static image (423). For example, the content may include a dynamic image related to a sense of color, a character, an atmosphere, a background, and / or a shape included in the static image.

[0103] An electronic device (101) according to one embodiment can provide a visual effect of extending a static image by providing content related to the static image contained within a frame (410). The electronic device (101) according to one embodiment can provide an enhanced user experience.

[0104] FIG. 7 is a flowchart illustrating an operation of an electronic device authenticating an external case according to one embodiment.

[0105] The operations described in FIG. 7 may be operations caused by an electronic device (e.g., an electronic device (101) of FIG. 2) when instructions stored in a memory (e.g., a memory (130) of FIG. 2) are executed by a processor (e.g., a processor (120) of FIG. 2).

[0106] Referring to FIG. 7, the memory (130) of an electronic device (e.g., the electronic device (101) of FIG. 2) can store programs (e.g., an accessory manager (710) and a screen change manager (720)) designed to change the screen of a cover display (e.g., a cover display (231) of FIG. 2). For example, a processor (e.g., the processor (120) of FIG. 2) can use the programs (e.g., the accessory manager (710) and the screen change manager (720)) designed to change the screen of the cover display (231) to perform an operation for authenticating an external case (e.g., an external case (401) of FIG. 4A) coupled to the electronic device (101) of FIG. 4A) and an operation for changing the screen displayed on the cover display (231).

[0107] In operation 701, the processor (120) may provide an identifier of the external case (401) and data related to the external case (401) to the accessory manager (710) via the first antenna (223) and the first wireless communication circuit (221).

[0108] For example, the processor (120) may use a first sensor (e.g., the first sensor (211) of FIG. 2) to identify that the location of the outer case (401) is within a specified distance from the electronic device (101). Based on identifying the engagement of the outer case (401) through the first sensor (211), the processor (120) may activate the first antenna (223). Through the activated first antenna (223), a communication channel between the electronic device (101) and the outer case (401) may be established.

[0109] For example, the identifier may be stored in a chip (422) located within the frame (410). The processor (120) may obtain the identifier by using a communication channel established through the first antenna (223) and the first wireless communication circuit (221). The processor (120) may provide the obtained identifier to the accessory manager (710).

[0110] In operation 703, the processor (120) may perform authentication on the external case (401) based on an identifier assigned to the external case (401) using the accessory manager (710). For example, the authentication may refer to an operation in which the processor (120) identifies the type of the external case (401) through the identifier assigned to the external case (401). For example, the processor (120) may identify, through the identifier assigned to the external case (401), whether the external case (401) coupled to the electronic device (101) is an external case (401) for changing a screen displayed through the cover display (231). For example, the processor (120) may identify, through the identifier assigned to the external case (401), whether data related to content provided by the external case (401) coupled to the electronic device (101) is secure data.

[0111] At operation 905, the processor (120) may release the communication channel established through the first antenna (223) and the first wireless communication circuit (221) based on completion of authentication for the external case (401).

[0112] For example, the processor (120) may deactivate the first antenna (223) based on completion of authentication for the external case (401). As the first antenna (223) is deactivated, the established communication channel may be released. For example, if the communication channel is maintained while the connection between the external case (401) and the electronic device (101) is maintained, power may be continuously consumed. By releasing the communication channel after the authentication is completed, unnecessary power consumption can be reduced. For example, if the communication channel is maintained while the connection between the external case (401) and the electronic device (101) is maintained, it may be difficult to establish a communication channel with an external electronic device (e.g., a credit card reader) through the first antenna (223). For example, the processor (120) may be configured to release the communication channel based on completion of the authentication in order to enable various functions provided using NFC communication. After authentication is completed, the communication channel is released, so that the electronic device (101) can perform NFC with an external electronic device using NFC.

[0113] In operation 707, the processor (120) may provide content-related data to the screen change manager (720) through the accessory manager (710) based on the authentication of the external case (401). For example, the processor (120) may provide (e.g., broadcast) a uniform resource identifier (URI) to the screen change manager (720) through the accessory manager (710). Based on the URI, the processor (120) may change the screen of the display (230) through the screen change manager (720). For example, the screen change manager (720) may change the screen based on calling the background screen API. For example, the screen change manager (720) may identify, among the contents stored in the memory (130), the first content to be displayed through the cover display (231). For example, the screen change manager (720) can control the cover display (231) so that the identified first content is displayed through the cover display (231). For example, the screen change manager (720) can download the second content from an external electronic device (402) (e.g., a server). For example, the screen change manager (720) can control the cover display (231) so that the downloaded second content is displayed through the cover display (231).

[0114] Figure 8 is a flowchart regarding an operation of changing content based on the SOC of the battery.

[0115] The operations described in FIG. 8 may be operations caused by an electronic device (e.g., an electronic device (101) of FIG. 2) when instructions stored in a memory (e.g., a memory (130) of FIG. 2) are executed by a processor (e.g., a processor (120) of FIG. 2).

[0116] Referring to FIG. 8, in operation 801, a processor (e.g., processor (120) of FIG. 2) may estimate the SOC of a battery (e.g., battery (189) of FIG. 2) while content is displayed through a cover display (e.g., cover display (231) of FIG. 2).

[0117] For example, the processor (120) can estimate the SOC of the battery (189) that supplies power to at least one component (e.g., the cover display (231)) of the electronic device (e.g., the electronic device (101) of FIG. 2). For example, the processor (120) can estimate the SOC of the battery (189), which represents the remaining capacity with respect to the total capacity of the battery (189), using a current integration method, an electric circuit model method, an electrochemical model method, and / or a data-based method. For example, the SOC can be calculated as a percentage (unit: %) of the remaining capacity with respect to the total capacity of the battery (189).

[0118] At operation 803, the processor (120) can identify whether the SOC of the battery (189) is below a threshold value.

[0119] For example, the processor (120) may compare the SOC of the battery (189) with a pre-stored threshold value. For example, the threshold value may be referred to as an SOC indicating a low power state of the battery (189). For example, the threshold value may be referred to as an SOC at which the discharge capacity (or remaining capacity) of the battery (189) is determined to be insufficient. For example, the threshold value may be, but is not limited to, 20% of the SOC. If the SOC of the battery (189) is less than the threshold value, the processor (120) may perform operation 805. If the SOC of the battery (189) is equal to or greater than the threshold value, the processor (120) may perform operation 807.

[0120] In operation 805, the processor (120) can change the content displayed on the cover display (231).

[0121] For example, the content displayed on the cover display (231) may include a dynamic image. For example, since the dynamic image includes multiple frames displayed over time, it may cause relatively high power consumption while the dynamic image is displayed on the cover display (231). The processor (120) may be configured to change the dynamic image to a static image based on estimating that the SOC of the battery (189) is below a threshold value. For example, since the static image includes a single frame, it may cause relatively low power consumption while the static image is displayed on the cover display (231). In a situation where the SOC of the battery (189) is low, the power consumption of the battery (189) may be reduced as the content displayed through the cover display (231) changes from a dynamic image to a static image. However, the present invention is not limited thereto. For example, the processor (120) may be configured to reduce the tone (e.g., brightness and / or saturation) of the content based on an estimation of the SOC of the battery (189) below a threshold value. As the tone of the content is reduced, the power consumption of the battery (189) may be reduced. This reduction in power consumption may increase the time required for the SOC of the battery (189) to be fully discharged.

[0122] In operation 807, the processor (120) can maintain content displayed on the cover display (231).

[0123] For example, if the SOC of the battery (189) is above a threshold value, the remaining capacity of the battery (189) may be sufficient. Since the remaining capacity of the battery (189) is sufficient, even if content that causes relatively high power consumption is displayed through the cover display (231), the battery (189) may not be completely discharged. The processor (120) may provide an enhanced user experience by maintaining the content displayed on the cover display (231) based on estimating the SOC above the threshold value.

[0124] FIG. 9A is a flowchart illustrating the operation of an electronic device according to the type of content displayed on the electronic device, according to one embodiment. FIG. 9B schematically illustrates a process for displaying first content through a cover display. FIG. 9C schematically illustrates a process for displaying second content through a cover display. FIG. 9D illustrates an example of a visual object for indicating the application of the second content.

[0125] The operations described in FIG. 9a may be operations caused by an electronic device (e.g., an electronic device (101) of FIG. 2) when instructions stored in a memory (e.g., a memory (130) of FIG. 2) are executed by a processor (e.g., a processor (120) of FIG. 2).

[0126] Referring to FIG. 9A, in operation 901, a processor (e.g., processor (120) of FIG. 2) may identify data acquired through a communication channel.

[0127] For example, the processor (120) may obtain data related to content through a communication channel. For example, the data may include information related to the content. For example, the information related to the content may be referenced as information indicating whether the content to be displayed through the cover display (e.g., the cover display (231) of FIG. 2) is the first content or the second content when the external case (e.g., the external case (401) of FIG. 2) is coupled. The processor (120) may be configured to identify whether the content to be displayed through the cover display (231) is the first content or the second content based on the data obtained through the first antenna (e.g., the first antenna (223) of FIG. 2) and the first wireless communication circuit (e.g., the first wireless communication circuit (221) of FIG. 2).

[0128] For example, content to be displayed through the cover display (231) may include first content and second content. For example, the first content may be referenced as content corresponding to the data among content pre-stored in a memory (e.g., memory (130) of FIG. 2). For example, the second content may be referenced as content downloaded through an external electronic device (e.g., external electronic device (402) of FIG. 2) (e.g., server) based on the data. The second content may be referenced as content stored in the memory (130) by being downloaded. For example, the first content may be referenced as preload content, and the second content may be referenced as download content.

[0129] In operation 903, the processor (120) may identify whether the content to be displayed through the cover display (231) is the first content based on the identified data. For example, the processor (120) may identify whether the identified content is the first content or the second content based on information related to the content included in the data. If the content identified in operation 903 is the first content, the processor (120) may perform operation 905.

[0130] In operation 905, the processor (120) can identify first content among the content stored in the memory (130) based on the URI data.

[0131] For example, the processor (120) may identify, among the contents stored in the memory (130), the first content corresponding to URI data obtained from a chip (e.g., chip (422) of FIG. 4B) inside the external case (401). For example, the first content may be related to an image included in one side of an external object (e.g., external object (420) of FIG. 4A) inserted in a frame (e.g., frame (410) of FIG. 4A).

[0132] In operation 907, the processor (120) may display first content through the cover display (231). For example, the processor (120) may control the cover display (231) so that the first content is displayed on the cover display (231).

[0133] Referring to FIG. 9B, a processor (e.g., processor (120) of FIG. 2) may obtain content-related data via NFC from an external case (401) including a chip (422). For example, the data may include URI data having a size of 23 bytes. For example, the format of the URI data may be set as shown in [Table 1] below. For example, the processor (120) may provide the URI data to the screen change manager (720) via the accessory manager (710).

[0134]

[0135] In the above [Table 1], the card may mean an external object (420). Referring to the above [Table 1], the 23-byte URI data may include a length field, a type field, a version field, a service type field, a service ID field, and a serial number field.

[0136] For example, the URI data length field may be set to a fixed value (e.g., 0x16). For example, the type field may be set to indicate which application (or module) will process the data acquired from the external case (401). For example, the version field may be set to a fixed value. For example, the service type field may indicate information about the content described above. For example, the service type field may indicate information indicating whether the content provided from the chip (422) is the first content or the second content. For example, the service ID field may indicate a unique ID for each type of the external case (401) (or the external object (420)). For example, in the case of the first content, any one of the contents stored in the memory (130) indicated by the service ID field may be specified. For example, in the case of the second content, any one of the contents stored in the external electronic device (402) (e.g., a server) may be specified by the service ID field. For example, the serial number field may be used to specify the screen displaying the content. However, the present invention is not limited thereto.

[0137] For example, the processor (120) may provide URI data to the data identification unit (910) through the accessory manager (710). The processor (120) may identify a service ID field included in the URI data through the data identification unit (910). Based on the value of the service ID field, the processor (120) may identify the first content stored in the memory (130). The processor (120) may provide information about a screen including the first content to the screen change manager (720). The processor (120) may change the screen of the cover display (231) to a screen including the first content through the screen change manager (720).

[0138] Referring again to FIG. 9A, if the content identified in operation 903 is not the first content (if the identified content is the second content), the processor (120) may perform operation 909.

[0139] In operation 909, the processor (120) may obtain second content from an external electronic device (402) through a second wireless communication circuit (e.g., the second wireless communication circuit (222) of FIG. 2) based on the URI data.

[0140] For example, the processor (120) may identify second content corresponding to URI data acquired from the chip (422) among content stored in an external electronic device (e.g., the external electronic device (402) of FIG. 2). For example, the second content may be related to an image included within one side of an external object (420) inserted within a frame (410).

[0141] In operation 911, the processor (120) may display second content through the cover display (231). For example, the processor (120) may control the cover display (231) so that the second content is displayed on the cover display (231).

[0142] Referring to FIG. 9c and FIG. 9b, the processor (120) can obtain content-related data from the chip (422) of the external case (401) via NFC. For example, the data can include URI data having a size of 23 bytes. For example, the processor (120) can provide the URI data to the screen change manager (720) via the accessory manager (710).

[0143] For example, the processor (120) may provide URI data to the data identification unit (910) through the accessory manager (710). The processor (120) may identify a service ID field included in the URI data through the data identification unit (910). Based on the value of the service ID field, the processor (120) may obtain information about second content to be downloaded through an external electronic device (402) (e.g., a server). For example, the processor (120) may identify an address for downloading information about the second content from the external electronic device (402) based on the value of the service ID field. As an example, the processor (120) may identify the value of the service ID field as part of the address. For example, the processor (120) may obtain the second content from the external electronic device (402).

[0144] For example, the electronic device (101) may include a second antenna (e.g., the second antenna (224) of FIG. 2) and a second wireless communication circuit (222). For example, the second antenna (224) and the second wireless communication circuit (222) may be used to perform cellular communication and / or wireless LAN communication with an external electronic device (402). For example, the processor (120) may download second content stored in the identified address through the second antenna (224) and the second wireless communication circuit (222). For example, the downloaded second content may be stored in the memory (130). The processor (120) may provide the second content to the screen change manager (720). The processor (120) may change the screen of the cover display (231) to a screen including the second content through the screen change manager (720).

[0145] Referring to FIG. 9d, the electronic device (101) may display a visual object (920) indicating that information about the second content is being acquired through the cover display (231). For example, the visual object (920) may include text such as “downloading…”. The visual object (920) may be displayed to overlap with the main screen (930). As the visual object (202) including the text is displayed, the user may recognize that the second content is being downloaded from an external electronic device (e.g., the external electronic device (402) of FIG. 9c). As the download of the second content is completed, the electronic device (101) may display a visual object (940) indicating that the second content is capable of being displayed through the cover display (231) within a state in which the second content can be displayed. For example, the visual object (940) may include text such as "content applied." For example, the visual object (940) may be displayed overlapping a screen (950) containing second content. The visual object (940) may disappear after a specified period of time has elapsed.

[0146] FIG. 10 is a flowchart illustrating an operation for deleting second content of an electronic device according to one embodiment.

[0147] The operations described in FIG. 10 may be operations caused by an electronic device (e.g., an electronic device (101) of FIG. 2) when instructions stored in a memory (e.g., a memory (130) of FIG. 2) are executed by a processor (e.g., a processor (120) of FIG. 2).

[0148] For example, the second content can be obtained from a chip (e.g., chip (422) of FIG. 4b) contained within an external object (e.g., external object (420) of FIG. 4b). For example, when an external object (420) is inserted into a frame (e.g., a frame (410) of FIG. 4A), an electronic device (e.g., an electronic device (101) of FIG. 2) can download second content based on URI data obtained from a chip (422) included in the external object (420). In order to change the content displayed on a cover display (e.g., a cover display (231) of FIG. 2), a user can replace the external object (420). When the external object (420) is replaced, new second content can be obtained from the chip (422) included in the replaced external object (420). Since the second content is stored in a memory (e.g., a memory (130) of FIG. 2), as the replacement of the external object (420) is repeated, the capacity of the second content stored in the memory (130) can increase. As the capacity of the second content increases, the capacity of the memory (130) The available capacity may be insufficient. According to one embodiment, the electronic device (101) can secure the capacity of the memory (130) by deleting the second content that has not been used for a specified period of time.

[0149] Referring to FIG. 10, in operation 1001, a processor (e.g., processor (120) of FIG. 2) may display second content through a cover display (231).

[0150] For example, the processor (120) may download second content from an external electronic device (e.g., an external electronic device (402) of FIG. 2) (e.g., a server) based on URI data obtained from an external case (e.g., an external case (401) of FIG. 2). The processor (120) may control the cover display (231) so that the downloaded second content is displayed through the cover display (231).

[0151] In operation 1003, the processor (120) can identify whether the external case (401) and the electronic device (101) are separated.

[0152] For example, the processor (120) can identify the coupling of the external case (401) and the electronic device (101) through the first sensor (e.g., the first sensor (211) of FIG. 2). For example, when a detection object (421) within the frame (410) is positioned within a specified distance from the first sensor (211), the first sensor (211) can provide an electrical signal based on the proximity of the detection object (421) to the processor (120). The processor (120) can identify that the external case (401) is coupled to the electronic device (101) based on the electrical signal provided from the first sensor (211). For example, when the external case (401) is separated from the electronic device (101), the detection object (421) within the frame (410) can move away from the specified distance from the first sensor (211). The first sensor (211) can provide an electrical signal to the processor (120) based on the separation of the detection object (421). The processor (120) can identify that the outer case (401) has been separated from the electronic device (101) based on the electrical signal provided from the first sensor (211).

[0153] In operation 1003, if the processor (120) identifies that the coupling between the external case (401) and the electronic device (101) is maintained, operation 1005 may be performed. In operation 1005, the processor (120) may maintain the display of the second content. For example, if the external case (401) is not separated from the electronic device (101) and maintains the coupling with the electronic device (101), the processor (120) may maintain the display of the second content. For example, the processor (120) may control the cover display (231) so that the second content is displayed through the cover display (231).

[0154] In operation 1003, if the processor (120) identifies separation of the external case (401) and the electronic device (101), operation 1007 may be performed. In operation 1007, the processor (120) may stop displaying the second content.

[0155] For example, a user may detach the outer case (401) from the electronic device (101) to change the second content displayed on the cover display (231) or to stop displaying the second content. For example, the processor (120) may identify the detachment of the outer case (401) when detaching the frame (410) coupled to the outer surface of the electronic device (101) or extracting an external object (420) inserted into the frame (410). The processor (120) may stop displaying the second content based on identifying the detachment of the outer case (401).

[0156] In operation 1009, the processor (120) can identify whether a specified period of time has elapsed since the timing at which the display of the second content was stopped.

[0157] For example, the processor (120) can identify the timing at which the outer case (401) is detached. The timing at which the outer case (401) is detached can be referred to as the timing at which the display of the second content is stopped. If another external object (420) is inserted into the frame (410) to display another second content, the processor (120) can display another second content through the cover display (231). The display of the other second content can be distinguished from the second content whose display is stopped. For example, the designated period of time can be a period during which it can be determined that the user detached the outer case (401) with the intention of not reusing the second content whose display is stopped for the time being. For example, the designated period of time can be referred to as one week (7 days), but is not limited thereto.

[0158] In operation 1009, if the processor (120) determines that a specified period of time has elapsed from the timing, operation 1011 may be performed. In operation 1011, the processor (120) may delete the second content stored in the memory (130).

[0159] For example, if a specified period of time has elapsed since the display of the second content was stopped, the processor (120) may delete the second content downloaded to the memory (130). Since the second content has not been reused for a considerable period of time, the processor (120) may delete the second content to secure the capacity of the memory (130).

[0160] In operation 1009, if the processor (120) determines that a specified period of time has not elapsed from the timing, operation 1013 may be performed. In operation 1013, the processor (120) may maintain the second content stored in the memory (130). For example, if a specified period of time has not elapsed from the timing at which the display of the second content was stopped, the user may insert an external object (420) corresponding to the second content into the frame (410) to display the second content again. Since the second content downloaded into the memory (130) has not been deleted, when the user inserts the external object (420) into the frame (410), the second content stored in the memory (130) may be displayed through the cover display (231) without the need to download the second content again. Since the second content is not deleted, there is no need for time to re-download the second content, and the second content can be quickly displayed again.

[0161] FIG. 11 is a flowchart of an operation based on a state of an electronic device according to one embodiment.

[0162] The operations described in FIG. 11 may be operations caused by an electronic device (e.g., an electronic device (101) of FIG. 2) when instructions stored in a memory (e.g., a memory (130) of FIG. 2) are executed by a processor (e.g., a processor (120) of FIG. 2).

[0163] Referring to FIG. 11, in operation 1101, a processor (e.g., processor (120) of FIG. 2) can identify a state of an electronic device (e.g., electronic device (101) of FIG. 2).

[0164] For example, the electronic device (101) may include a third sensor (e.g., the third sensor (213) of FIG. 2) used to identify a state of the electronic device (101) (e.g., a folded state, an unfolded state, and / or an intermediate state). The third sensor (213) may include one or more magnets and / or one or more magnetic sensors. At least one of the one or more magnets included in the third sensor (213) or the one or more magnetic sensors may be disposed at different locations within the electronic device (101). The positional relationship of the one or more magnets and / or the one or more magnetic sensors within the electronic device (101) may change depending on the state of the electronic device (101). The electronic device (101) may measure a change in the positional relationship through the one or more magnetic sensors. The change in the positional relationship may cause a change in a magnetic field formed by the one or more magnets. The electronic device (101) can obtain an electric signal indicating a change in the magnetic field using the third sensor (213). For example, the electronic device (101) can identify the state of the electronic device (101) using the electric signal obtained from the third sensor (213).

[0165] In operation 1103, the processor (120) can identify whether the state of the electronic device (101) is a folding state. For example, the processor (120) can identify whether the electronic device (101) is a folding state based on an electrical signal provided from the third sensor (213). For example, the processor (120) can identify that the electronic device (101) has transitioned from an unfolding state to a folding state.

[0166] In operation 1103, if the processor (120) identifies a folding state of the electronic device (101), operation 1105 may be performed. In operation 1105, the processor (120) may deactivate the cover display (e.g., the cover display (231) of FIG. 2) based on the elapse of a specified time from the timing at which the folding state was identified.

[0167] For example, when the electronic device (101) is in a folded state, the electronic device (101) may not be used by the user. For example, if content continues to be displayed through the cover display (231) while the user is not using the electronic device (101) in a folded state, unnecessary power consumption may occur. The processor (120) can reduce unnecessary power consumption by deactivating the cover display (231) based on a specified time elapsed from the time when the folded state is identified. The specified time may be about 30 seconds, but is not limited thereto. The specified time may be preset by the user.

[0168] In operation 1103, if the processor (120) does not identify the folding state of the electronic device (101), operation 1107 may be performed. In operation 1107, the processor (120) may display content through the cover display (231).

[0169] For example, when the electronic device (101) is in an unfolded state and / or an intermediate state, the electronic device (101) can be used. For example, while a user is using the electronic device (101) in an unfolded state and / or an intermediate state, content can be displayed through the cover display (231). By displaying content through the cover display (231) while the electronic device (101) is being used by the user, the user experience can be enhanced.

[0170] For example, the electronic device (101) may include a second sensor (e.g., the second sensor (212) of FIG. 2) for user input (e.g., touch input) provided through the cover display (231). For example, the second sensor (212) may include a touch sensor. For example, the processor (120) may be configured to identify the user input provided through the cover display (231) through the second sensor (212). According to one embodiment, the second sensor (212) may operate based on the state of the electronic device (101).

[0171] For example, in operation 1109, the processor (120) may activate the second sensor (212). For example, when the electronic device (101) is in a folded state, the processor (120) may identify a user input to the cover display (231) through the activated second sensor (212). In the folded state, the flexible display (232) may not be visible from the outside, and thus, user input to the flexible display (232) may not be possible. According to one embodiment, the electronic device (101) may activate the second sensor (212) to receive a user input to the cover display (231) in the folded state in which the user input to the flexible display (232) cannot be received.

[0172] For example, in operation 1111, the processor (120) may deactivate the second sensor (212). For example, when the electronic device (101) is in an unfolded state, the processor (120) may receive a user input provided through the flexible display (232) exposed to the outside. According to one embodiment, the electronic device (101) may deactivate the second sensor (212) to block a user input to the cover display (231) in an unfolded state in which a user input to the flexible display (232) can be received.

[0173] Figure 12 illustrates an exemplary process for changing content displayed on a cover display.

[0174] Referring to FIG. 12, the content displayed on the cover display (231) can be performed by changing an external object (420) including a chip (422).

[0175] For example, the outer case (401) may include a frame (410) and an external object (420). The frame (410) may be coupled to the electronic device (101), and the external object (420) may be inserted into the frame (410).

[0176] Referring to state 1201, within a state in which the external case (401) is coupled, content can be displayed through the cover display (231). For example, state 1301 can be referred to as a state in which a first external object (420-1) is inserted within a frame (410). Within a state in which the first external object (420-1) is inserted, a screen (1202) including content corresponding to the first external object (420-1) can be displayed through the cover display (231).

[0177] Referring to state 1203, when the first external object (420-1) is withdrawn from the frame (410), the electronic device (101) can identify that the external case (401) is separated through the first sensor (e.g., the first sensor (211) of FIG. 2). For example, when the distance between the first sensor (211) and the detection object (421) exceeds a specified distance, the processor (120) can identify the separation of the external case (401) and the electronic device (101). Based on identifying the separation, the processor (120) can stop displaying content corresponding to the first external object (420-1) through the cover display (231). When the display of the content corresponding to the first external object (420-1) is stopped, the cover display (231) can display the basic screen (1204). For example, the default screen (1204) may be referred to as a screen that does not contain content. For example, the default screen may display basic information such as the time and date.

[0178] Referring to state 1205, a second external object (420-2) different from the first external object (420-1) may be inserted into the frame (410). For example, a chip (422) included in the second external object (420-2) may include different information than the chip (422) included in the first external object (420-1). When the second external object (420-2) is inserted into the frame (410), the electronic device (101) may identify the coupling of the external case (401) through the first sensor (211). For example, when the distance between the first sensor (211) and the detection object (421) is within a specified distance, the processor (120) may identify the coupling of the external case (401) and the electronic device (101).

[0179] Referring to state 1207, content corresponding to the second external object (420-2) may be displayed. For example, the processor (120) may control the cover display (231) to display content corresponding to the second external object (420-2) based on data acquired from the chip (422) included in the second external object (420-2). For example, a screen (1208) including content corresponding to the second external object (420-2) may be displayed through the cover display (231). The content may be related to an image (423) included on one side of the second external object (420-2).

[0180] In one embodiment, as the external object (420) is replaced, the content displayed through the cover display (231) may change. Since various contents may be provided depending on the external object (420), the user experience may be enhanced.

[0181] Figure 13 is a flowchart regarding an operation of changing content based on an external environment.

[0182] The operations described in FIG. 13 may be operations caused by an electronic device (e.g., an electronic device (101) of FIG. 2) when instructions stored in a memory (e.g., a memory (130) of FIG. 2) are executed by a processor (e.g., a processor (120) of FIG. 2).

[0183] Referring to FIG. 13, in operation 1301, a processor (e.g., processor (120) of FIG. 2) can identify the brightness of an external environment through a light sensor.

[0184] For example, an electronic device (e.g., the electronic device (101) of FIG. 2) may include a light sensor for identifying the brightness of an external environment of the electronic device (101). For example, the light sensor may provide an electrical signal representing the brightness of the external environment to a processor (120). The processor (120) may identify the brightness of the external environment based on the electrical signal.

[0185] In operation 1303, the processor (120) may change the content displayed on the cover display (e.g., the cover display (231) of FIG. 2) based on the identified brightness.

[0186] For example, the processor (120) can adjust the brightness of the content according to the brightness of the external environment. For example, if the processor (120) determines through the light sensor that the brightness of the external environment is sufficient, the processor (120) can control the cover display (231) so that content that matches the brightness of the external environment is displayed through the cover display (231). For example, if the processor (120) determines through the light sensor that the brightness of the external environment is insufficient, the processor (120) can control the cover display (231) so that bright content is displayed through the cover display (231).

[0187] An electronic device (101) is provided. The electronic device (101) may include a first housing (310). The electronic device (101) may include a second housing (320). The electronic device (101) may include a hinge structure (365) that rotatably connects the first housing (310) and the second housing (320). The electronic device (101) may include a cover display (231) disposed on one surface (e.g., at least a portion of the second surface (312)) of the first housing (310). The electronic device (101) may include a first wireless communication circuit (221) configured to communicate via a first antenna (223). The electronic device (101) may include a memory (130) that includes one or more storage media that store instructions. The electronic device (101) may include a processor (120) including a processing circuit. The instructions, when individually or collectively executed by the processor (120), may cause the electronic device (101) to establish a communication channel with the external case (401) through the first antenna (223) and the first wireless communication circuit (221) based on identifying a coupling between the external case (401) and the electronic device (101) (e.g., the second housing (320)) through the first sensor (211). The instructions, when individually or collectively executed by the processor (120), may cause the electronic device (101) to obtain data related to an identifier and content assigned to the external case (401) through the communication channel. The above instructions, when individually or collectively executed by the processor (120), may cause the electronic device (101) to identify content to be displayed through the cover display (231) based on the acquired data.The instructions, when individually or collectively executed by the processor (120), may cause the electronic device (101) to control the cover display (231) so that the identified content is displayed through the cover display (231). The instructions, when individually or collectively executed by the processor (120), may be configured to cause the electronic device (101) to estimate the state of charge (SOC) of the battery (189) while the content is displayed through the cover display (231). The electronic device (101) according to one embodiment may provide an enhanced user experience by displaying a screen including content through the cover display (231). In order to reduce power consumption due to display of content, the electronic device (101) may be configured to estimate the SOC of the battery (189) and control the cover display (231) based on the estimated SOC.

[0188] For example, the instructions, when individually or collectively executed by the processor (120), may cause the electronic device (101) to maintain the content displayed through the cover display (231) based on an estimation that the SOC of the battery (189) is greater than or equal to a threshold value. The instructions, when individually or collectively executed by the processor (120), may cause the electronic device (101) to change the content displayed through the cover display (231) based on an estimation that the SOC of the battery (189) is less than a threshold value. For example, when the remaining capacity of the battery (189) is insufficient, the content may be changed to reduce power consumption. For example, the changed content may consume less power than the content before being changed.

[0189] For example, the instructions, when individually or collectively executed by the processor (120), may cause the electronic device (101) to change the content displayed on the cover display (231) by changing a dynamic image included in the content to a static image.

[0190] For example, the instructions, when individually or collectively executed by the processor (120), may cause the electronic device (101) to identify, from among the contents stored in the memory (130), a first content to be displayed through the cover display (231) based on information related to the content included in the data. For example, the first content may be referenced as preloaded content previously stored in the memory (130).

[0191] For example, the electronic device (101) may further include a second wireless communication circuit (222) configured to communicate via a second antenna (224). The instructions, when individually or collectively executed by the processor (120), may cause the electronic device (101) to download second content from an external electronic device (402) via the second antenna (224) and the second wireless communication circuit (222), based on the data. The instructions, when individually or collectively executed by the processor (120), may cause the electronic device (101) to control the cover display (231) such that the stored second content is displayed via the cover display (231). For example, the second content may be referred to as downloaded content obtained from an external electronic device (402) (e.g., a server).

[0192] For example, the instructions, when individually or collectively executed by the processor (120), may cause the electronic device (101) to identify uniform resource identifier (URI) data included in the data. The instructions, when individually or collectively executed by the processor (120), may cause the electronic device (101) to obtain the second content through the second wireless communication circuit (222) based on the identified URI data.

[0193] For example, the instructions, when individually or collectively executed by the processor (120), may cause the electronic device (101) to maintain display of the content through the cover display (231) based on identifying, through the first sensor (211), that the coupling between the external case (401) and the electronic device (101) is maintained. The instructions, when individually or collectively executed by the processor (120), may cause the electronic device (101) to stop displaying the second content through the cover display (231) based on identifying, through the first sensor (211), that the external case (401) and the electronic device (101) are separated. The above instructions, when individually or collectively executed by the processor (120), may cause the electronic device (101) to delete the downloaded second content based on the elapsed time period from the time when the display of the second content was stopped. For example, the electronic device (101) may delete the second content that has not been used for a certain period of time to secure capacity of the memory (130). As the second content that has not been used for a certain period of time is deleted, the capacity of the memory (130) can be secured.

[0194] For example, the instructions, when individually or collectively executed by the processor (120), may cause the electronic device (101) to authenticate the outer case (401) based on the identifier. The instructions, when individually or collectively executed by the processor (120), may cause the electronic device (101) to release the communication channel based on completion of the authentication. For example, if the communication channel is maintained while the coupling between the outer case (401) and the electronic device (101) is maintained, it may be difficult to establish a communication channel with an external electronic device (e.g., a credit card reader) through the first antenna (223). For example, the processor (120) may be configured to release the communication channel based on completion of the authentication in order to enable various functions provided using NFC communication. After authentication is completed, the communication channel is released, so that the electronic device (101) can perform NFC with an external electronic device using NFC.

[0195] For example, the instructions, when individually or collectively executed by the processor (120), may cause the electronic device (101) to identify a coupling of the outer case (401) based on identifying a detection object (421) contained within an external object (420) inserted into a frame (410) of the outer case (401) through the first sensor (211). For example, the detection object (421) may be a magnet, and the first sensor (211) may be a Hall sensor. When the detection object (421) is positioned within a specified distance from the first sensor (211), the first sensor (211) may provide an electrical signal based on the detection object (421) to the processor (120). The processor (120) may identify a coupling of the outer case (401) based on the electrical signal.

[0196] For example, the electronic device (101) may further include a flexible display (232) disposed on another side of the electronic device (101) opposite to the first side (e.g., the first side (311) and the third side (321)). The flexible display (232) may include a first display area (232a), a second display area (232b), and a third display area (232c). The first display area (232a) may be disposed on the first housing (310). The second display area (232b) may be disposed on the second housing (320). The third display area (232c) may be disposed between the first display area (232a) and the second display area (232b). The third display area (232c) may be deformable based on the second housing (320) that rotates relative to the first housing (310).

[0197] For example, the cover display (231) may be placed on one side (e.g., the second side (312)) of the first housing (310). The first antenna (223) may be placed within the second housing (320). The first antenna (223) may include an antenna for short-range wireless communication.

[0198] For example, the first housing (310) may include a first surface (311) and a second surface (312) opposite to the first surface (311). The second housing (320) may include a third surface (321) and a fourth surface (322) opposite to the third surface (321). The electronic device (101) may be capable of switching from a folded state in which a first direction toward which the first surface (311) faces and a second direction toward which the third surface (321) faces are the same to an unfolded state in which the first direction is opposite to the second direction. The cover display (231) may be disposed on the second surface (312).

[0199] For example, the electronic device (101) may further include a second sensor (212) for user input provided through the cover display (231). The processor (120) may be configured to identify user input provided through the cover display (231) through the second sensor (212) within the folded state. The processor (120) may be configured to deactivate the second sensor (212) within the unfolded state.

[0200] For example, the processor (120) may be configured to activate the cover display (231) so that the content is displayed on the cover display (231) based on identifying the unfolded state of the electronic device (101).

[0201] For example, the processor (120) may identify the folding state of the electronic device (101). The processor (120) may be configured to deactivate the cover display (231) based on a specified time elapsed from the timing at which the folding state is identified.

[0202] A method of an electronic device (101) is provided. The method may include an operation of identifying a coupling between an external case (401) and the electronic device (101) through a first sensor (211), an operation of establishing a communication channel with the external case (401) through a first antenna (223) and a first wireless communication circuit (221) of the electronic device (101), an operation of obtaining an identifier assigned to the external case (401) and data related to the content through the communication channel, an operation of identifying content to be displayed through a cover display (231) of the electronic device (101) based on the obtained data, an operation of controlling the cover display (231) so that the identified content is displayed through the cover display (231), and an operation of estimating a state of charge (SOC) of a battery (189) by the electronic device (101) while the content is displayed through the cover display (231).

[0203] For example, the method may further include an operation of maintaining the content displayed through the cover display (231) based on estimating that the SOC of the battery (189) is greater than or equal to a threshold value, and an operation of changing the content displayed through the cover display (231) based on estimating that the SOC of the battery (189) is less than or equal to a threshold value.

[0204] For example, the method may further include an operation of identifying a first content to be displayed through the cover display (231) among the content stored in the memory (130) based on information related to the content included in the data.

[0205] For example, the method may further include an operation of downloading second content from an external electronic device (402) through a second antenna (224) and a second wireless communication circuit (222) of the electronic device (101) based on the data, and an operation of controlling the cover display (231) so that the stored second content is displayed through the cover display (231).

[0206] The method may further include an operation of authenticating the external case (401) based on the identifier and an operation of releasing the communication channel based on completion of the authentication.
