Electronic device 101 can communicate with external electronic device 104 via server 108. Electronic device 101 may include processor 120, memory 130, input module 150, sound output module 155, display module 160, audio module 170, sensor module 176, interface 177, connector 178, haptic module 179, camera module 180, power management module 188, battery 189, communication module 190, subscriber identification module (SIM) 196, and / or antenna module 197. In some embodiments of this disclosure, at least one of the above-mentioned components (e.g., connector 178) may be omitted from electronic device 101, or one or more other components may be added to electronic device 101. In some embodiments of this disclosure, some components may be implemented as a single integrated circuit. For example, sensor module 176, camera module 180, or antenna module 197 may be implemented as embedded in a single component (e.g., display module 160).

[0028] Processor 120 can run software (e.g., program 140) to control at least one other component (e.g., hardware or software component) of electronic device 101 connected to processor 120, and can perform various data processing or calculations. As at least part of the data processing or calculations, processor 120 can store commands or data received from another component (e.g., sensor module 176 or communication module 190) in volatile memory 132, process the commands or data stored in volatile memory 132, and store the resulting data in non-volatile memory 134.

Additionally or alternatively, auxiliary processor 123 may be adapted to consume less power than main processor 121, or adapted to be dedicated to a specific function. The auxiliary processor 123 can be implemented separately from the main processor 121, or it can be implemented as part of the main processor 121.

[0029] When the main processor 121 is inactive (e.g., in sleep) state, the auxiliary processor 123 (rather than the main processor 121) can control at least some of the functions or states associated with at least one component of the electronic device 101 (e.g., display module 160, sensor module 176, or communication module 190), or when the main processor 121 is active (e.g., running an application), the auxiliary processor 123 can work with the main processor 121 to control at least some of the functions or states associated with at least one component of the electronic device 101 (e.g., display module 160, sensor module 176, or communication module 190). The auxiliary processor 123 (e.g., an image signal processor (ISP) or communication processor (CP)) can be implemented as part of another component (e.g., camera module 180 or communication module 190) functionally associated with the auxiliary processor 123. According to embodiments of this disclosure, the auxiliary processor 123 (e.g., a neural network processing device) can include hardware architectures specifying the processing of artificial intelligence models.

The receiver can be implemented separately from the speaker or as part of the speaker.

[0034] Display module 160 can visually provide information to the outside of electronic device 101 (e.g., to a user). Display device 160 may include, for example, a display, a holographic device, or a projector, and control circuitry for controlling a corresponding one of the display, holographic device, and projector. Display module 160 may include touch circuitry (e.g., a touch sensor) adapted to detect touch, or sensor circuitry (e.g., a pressure sensor) adapted to measure the force of a touch.

[0035] Audio module 170 can convert sound into electrical signals and vice versa. Audio module 170 can obtain sound via input module 150, or output sound via sound output module 155 or headphones of an external electronic device (e.g., external electronic device 102) that is directly (e.g., wired) or wirelessly connected to electronic device 101.

[0036] Sensor module 176 can detect the operating state of electronic device 101 (e.g., power or temperature) or the environmental state outside electronic device 101 (e.g., user state), and then generate an electrical signal or data value corresponding to the detected state. Sensor module 176 may include, for example, a gesture sensor, gyroscope sensor, atmospheric pressure sensor, magnetic sensor, accelerometer, grip sensor, proximity sensor, color sensor, infrared (IR) sensor, biometric sensor, temperature sensor, humidity sensor, or illuminance sensor.

The haptic module 179 may include, for example, a motor, a piezoelectric element, or an electrical stimulator.

[0040] Camera module 180 can capture still or moving images. Camera module 180 may include one or more lenses, an image sensor, an image signal processor, or a flash.

[0041] The power management module 188 can manage the power supplied to or consumed by the electronic device 101. The power management module 188 can be implemented as at least part of, for example, a power management integrated circuit (PMIC).

[0042] Battery 189 can power at least one component of electronic device 101. Battery 189 may include, for example, a non-rechargeable primary battery, a rechargeable rechargeable battery, and / or a fuel cell.

[0043] Communication module 190 can support the establishment of a direct (e.g., wired) or wireless communication channel between electronic device 101 and external electronic devices (e.g., external electronic device 102, external electronic device 104, or server 108), and perform communication via the established communication channel. Communication module 190 may include one or more communication processors capable of operating independently of processor 120 (e.g., application processor (AP)) and supporting direct (e.g., wired) or wireless communication. Communication module 190 may include wireless communication module 192 (e.g., cellular communication module, short-range wireless communication module, or Global Navigation Satellite System (GNSS) communication module) or wired communication module 194 (e.g., local area network (LAN) communication module or power line communication (PLC) module). One of these communication modules can communicate with an external electronic device via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wi-Fi Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, 5G network, next-generation communication network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip) or as multiple components (e.g., multiple chips) that are separate from each other. The wireless communication module 192 can identify and verify the electronic device 101 in the communication network (such as the first network 198 or the second network 199) using user information (e.g., the International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.

[0044] Wireless communication module 192 can support 5G networks following 4G networks and next-generation communication technologies (such as new radio (NR) access technologies). NR access technologies can support enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), or ultra-reliable low-latency communication (URLLC). Wireless communication module 192 can support high-frequency bands (e.g., millimeter-wave bands) to achieve, for example, high data transmission rates. Wireless communication module 192 can support various technologies for guaranteeing performance in high-frequency bands, such as, for example, beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, or massive antennas. The wireless communication module 192 of this disclosure can support various requirements specified in electronic device 101, external electronic device (e.g., external electronic device 104), or network system (e.g., second network 199). According to the implementation, the wireless communication module 192 may support peak data rates (e.g., 20 Gbps or greater) for implementing eMBB, lost coverage (e.g., 164 dB or less) for implementing mMTC, or U-plane delay (e.g., 0.5 ms or less for each of the downlink (DL) and uplink (UL), or 1 ms or less round trip) for implementing URLLC.

[0045] Antenna module 197 can transmit or receive signals or power to or from the exterior of electronic device 101 (e.g., external electronic device). Antenna module 197 may include an antenna comprising a radiating element formed of a conductive material or conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)). According to embodiments, antenna module 197 may include multiple antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication scheme used in a communication network (such as a first network 198 or a second network 199) can be selected from the multiple antennas by, for example, communication module 190 (e.g., wireless communication module 192). Signals or power can then be transmitted or received between communication module 190 and the external electronic device via the selected at least one antenna. Additional components besides the radiating element (e.g., a radio frequency integrated circuit (RFIC)) may be additionally incorporated into antenna module 197.

[0046] According to various embodiments of this disclosure, antenna module 197 can form a millimeter-wave antenna module. According to embodiments of this disclosure, the millimeter-wave antenna module may include a printed circuit board, a radio frequency integrated circuit (RFIC), and multiple antennas (e.g., an array antenna), wherein the RFIC is disposed on or adjacent to a first surface (e.g., a bottom surface) of the printed circuit board and is capable of supporting a specified high-frequency band (e.g., a millimeter-wave band), and the multiple antennas are disposed on or adjacent to a second surface (e.g., a top surface or a side surface) of the printed circuit board and are capable of transmitting or receiving signals of the specified high-frequency band.

[0047] At least some of the aforementioned components can be interconnected and communicate signals (e.g., commands or data) between them via an inter-peripheral communication scheme (e.g., bus, general purpose input / output (GPIO), serial peripheral interface (SPI), or mobile industrial processor interface (MIPI)).

[0048] Commands or data can be transmitted or received between electronic device 101 and external electronic device 104 via server 108 connected to the second network 199. Each of electronic device 102 or electronic device 104 can be a device of the same type as electronic device 101, or a device of a different type. All or some operations to be performed on electronic device 101 can be performed on one or more of external electronic devices 102, external electronic devices 104, or server 108. For example, if electronic device 101 is required to automatically perform a function or service, or is required to perform a function or service in response to a request from a user or another device, electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service instead of running the function or service, or electronic device 101 may request the one or more external electronic devices to perform at least a portion of the function or service in addition to running the function or service. Upon receiving the request, the one or more external electronic devices may perform the requested at least portion of the function or service, or perform additional functions or services related to the request, and transmit the result of the execution to electronic device 101. Electronic device 101 may provide the result as at least a partial response to the request, with or without further processing of the result. For this purpose, technologies such as cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing can be used. Electronic device 101 may use, for example, distributed computing or mobile edge computing to provide ultra-low latency services. In another embodiment of this disclosure, external electronic device 104 may include an Internet of Things (IoT) device. Server 108 may be an intelligent server using machine learning and / or neural networks. According to embodiments of this disclosure, external electronic device 104 or server 108 may be included in a second network 199. Electronic device 101 can be applied to intelligent services (e.g., smart homes, smart cities, smart cars, or healthcare) based on 5G communication technology or IoT-related technologies.

[0049] The electronic device according to embodiments of this disclosure can be one of various types of electronic devices. The electronic device may include a portable communication device (e.g., a smartphone), a computer device, a portable multimedia device, a portable medical device, a camera, a wearable device, or a home appliance. However, the electronic device is not limited to any of the above.

[0050] The various embodiments of this disclosure and the terminology used herein are not intended to limit the technical features described herein to a particular embodiment, and include various changes, equivalents, or alternatives for corresponding embodiments. In the description of the drawings, similar reference numerals may be used to refer to similar or related elements. It will be understood that nouns in the singular form corresponding to terms may include one or more things unless the relevant context clearly indicates otherwise. As used herein, each of the phrases such as “A or B,” “at least one of A and B,” “at least one of A or B,” “A, B, or C,” “at least one of A, B, and C,” and “at least one of A, B, or C” may include any one or all possible combinations of the items listed together with the corresponding phrase among the plurality of phrases. As used herein, terms such as “first” and “second” or “first” and “second” may be used to simply distinguish one component from another and do not limit the components in other respects (e.g., importance or order). It will be understood that, whether the terms “operably” or “communically” are used or not, if an element (e.g., a first element) is referred to as “combined with another element (e.g., a second element),” “combined to another element (e.g., a second element),” “connected to another element (e.g., a second element),” or “attached to another element (e.g., a second element)”, it means that the first element can be directly (e.g., wired) connected to the second element, wirelessly connected to the second element, or connected to the second element via a third element.

[0051] The term "module" can include units implemented in hardware, software, or firmware, and can be used interchangeably with other terms (e.g., "logic," "logic block," "part," or "circuit"). A module can be a single integrated component adapted to perform one or more functions, or the smallest unit or part of such a single integrated component.

[0052] The various embodiments described herein can be implemented as software (e.g., program 140) containing one or more instructions that can be read by a machine (e.g., electronic device 101) and stored in a storage medium (e.g., internal memory 136 or external memory 138). For example, under the control of a processor, the processor (e.g., processor 120) of the machine (e.g., electronic device 101) can invoke and execute at least one of the one or more instructions stored in the storage medium, with or without the use of one or more other components. This enables the machine to operate to perform at least one function according to the invoked at least one instruction. The one or more instructions may include code generated by a compiler or code that can be run by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. The term "non-transitory" simply means that the storage medium is a tangible device and does not include signals (e.g., electromagnetic waves), but this term does not distinguish between data being stored semi-permanently in the storage medium and data being temporarily stored in the storage medium.

[0053] The method according to embodiments of this disclosure may be included and provided in a computer program product. The computer program product can be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., a compact disk read-only memory (CD-ROM)) or may be distributed via an app store (e.g., a Playstore).

One or more of the aforementioned components may be omitted, or one or more other components may be added. Alternatively or additionally, multiple components (e.g., modules or programs) may be integrated into a single component. In this case, the integrated component may perform one or more functions of each of the multiple components in the same or similar manner as one or more functions performed by a corresponding component of the multiple components prior to integration. Operations performed by a module, program, or other component may be performed sequentially, in parallel, repeatedly, or tentatively, or one or more operations may be performed in a different order or omitted, or one or more other operations may be added.

[0055] Figure 2 An electronic device 2 according to an embodiment is illustrated. Figure 3 A portion of the electronic device 2 according to an embodiment is shown along... Figure 2 The cross-sectional structure of line A-A' in the yz plane is 300. Figure 4 The following is illustrated according to an embodiment. Figure 2 A portion of the shell 20 has a cross-sectional structure 400 in the xz plane. Figure 5 According to the embodiments Figure 2 A plan view of the flexible display module 30 in the unfolded state included in the electronic device 2.

[0056] refer to Figure 2 and Figure 3 Electronic device 2 (e.g., Figure 1 The electronic device 101 may include a housing (or housing structure) 20, a flexible display module 30, a columnar roller 40, a first bending mechanism 50, a second bending mechanism 60, a printed circuit board 70, and / or a battery 80 (e.g., Figure 1 Battery 189 in the middle.

[0057] Figure 2 An electronic device 2 in a first state is shown. For example, the first state of electronic device 2 can refer to a state where the flexible display module 30 is moved to the interior space of the housing 20 by a certain amount (e.g., to a maximum extent), such that the display area (or screen) seen from the outside is reduced. In one embodiment, in the first state of electronic device 2, as shown, a substantially non-externally visible display area may not be formed. In a particular embodiment, electronic device 2 may be implemented such that an externally visible display area is formed in the first state. The first state of electronic device 2 can be referred to by various other terms corresponding to the state in which the flexible display module 30 is not pulled out of the housing 20 (e.g., the closed state).

[0058] At least a portion of the flexible display module 30 can be introduced (e.g., inserted) into the interior space of the housing 20 while being circularly rolled around a first axis C1 (e.g., a rolling axis). In one embodiment, the housing 20 may include a first surface 201 and a second surface 202 positioned spaced apart in a direction extending along the first axis C1 (e.g., the x-axis direction). The first surface 201 may face a first direction (e.g., the -x-axis direction) and form one surface of the electronic device 2, and the second surface 202 may face a second direction opposite to the first direction (e.g., the +x-axis direction) and form another surface of the electronic device 2. The housing 20 may include a third surface 203 (e.g., an outer surface or side surface) of the electronic device 2 surrounding the space between the first surface 201 and the second surface 202. The housing 20 may include an opening 204 on the third surface 203, through which the flexible display module 30 can be introduced into the interior space of the housing 20 or pulled out of the housing 20 through the opening 204. In a particular embodiment, housing 20 may refer to a structure that includes at least a portion of a first surface 201, a second surface 202, and a third surface 203. For example, housing 20 may include a plurality of housing components connected to each other to form the outer surface of electronic device 2.

[0059] According to an embodiment, the cylindrical roller 40 can be positioned inside the housing 20 to be rotatable about a first axis C1. When the flexible display module 30 is introduced into the interior space of the housing 20 through the opening 204 or pulled out of the housing 20 through the opening 204, there may be a transition between the movement of the flexible display module and the rotational movement of the cylindrical roller 40. For example, when the flexible display module 30 is introduced into the interior space of the housing 20, at least a portion of the flexible display module 30 may be introduced into the interior space of the housing 20 while rolling on the cylindrical outer surface of the cylindrical roller 40 rotating about the first axis C1. The cylindrical outer surface of the cylindrical roller 40 may be a circular outer peripheral surface (e.g., a cylindrical surface) spaced apart from the first axis C1 by a corresponding radius.

[0060] According to an embodiment, the electronic device 2 may include a drive module (not shown) associated with the rotation of the cylindrical roller 40 or the movement of the flexible display module 30. For example, the drive module may rotate the cylindrical roller 40, thereby facilitating the movement of the flexible display module 30. Alternatively, the drive module may move the flexible display module 30, and the cylindrical roller 40 may rotate accordingly. In one embodiment, the drive module may include an elastic structure that applies a resilient force to the cylindrical roller 40, causing the cylindrical roller 40 to rotate or the flexible display module 30 to move. For example, the elastic structure included in the drive module may cause the cylindrical roller 40 to rotate or the flexible display module 30 to move without the need for an electric drive device such as a motor.

[0061] According to an embodiment, the flexible display module 30 (see...) Figure 3 and Figure 5 The flexible display module 30 may include a front surface 30A, a rear surface 30B facing the opposite direction to the front surface 30A, and a side surface 30C connecting the front surface 30A and the rear surface 30B. Light generated by the display panel included in the flexible display module 30 can propagate outward through the front surface 30A. The side surface 30C of the flexible display module 30 may include a first side surface 301, a second side surface 302, a third side surface 303, or a fourth side surface 304. The first side surface 301 and the second side surface 302 may be located on opposite sides. The third side surface 303 and the fourth side surface 304 may be located on opposite sides. The third side surface 303 may be connected to one end of the first side surface 301 and one end of the second side surface 302. The fourth side surface 304 may be connected to the other end of the first side surface 301 and the other end of the second side surface 302. The first end 311 of the third side surface 303 forming the flexible display module 30 may be connected to the columnar roller 40. In the first state of the electronic device 2, the second end 312 of the fourth side surface 304 of the flexible display module 30 can be positioned externally through the opening 204 of the housing 20.

Figure 5 The handle 90 can be implemented as a flexible element so as not to compromise the flexibility of the flexible display module 30. In a particular embodiment (not shown), the electronic device 2 can be implemented such that in a first state of the electronic device 2, the second end 312 is not exposed to the outside of the housing 20 while the handle 90 is exposed to the outside.

The second distance L2 between the third inner surface 204C and the fourth inner surface 204D can be formed to be greater than the thickness T of the flexible display module 30 (e.g., the distance between the front surface 30A and the rear surface 30B).

[0064] According to an embodiment, the flexible display module 30 may include a display area (or, active area) 31 and a non-display area (or, passive area) 32. The display area 31 is a portion forming the screen of the electronic device 2 and may include a light-emitting layer containing multiple pixels (e.g., an organic light-emitting diode (OLED) or a micro light-emitting diode (micro LED)). In an embodiment, the display area 31 may be at least partially surrounded by the non-display area 32. For example, a first boundary B1, a second boundary B2, a third boundary B3, or a fourth boundary B4 may exist between the display area 31 and the non-display area 32.

The third portion 73 may be connected to the columnar roller 40 (see...). Figure 3 The first portion 71 and / or the third portion 73 may be formed to have a first width W1 between the first side surface 301 and the second side surface 302. In one embodiment, the second portion 72 may be formed to have a second width W2 that is smaller than the first width W1. Hereinafter, the first portion 71 may be referred to as the screen portion, and the second portion 72 may be referred to as the neck of the flexible display module.

[0068] According to an embodiment, the flexible display module 30 may include a first notch 810 and / or a second notch 820 formed in the non-display area 32. The first notch 810 may be, for example, a first opening penetrating between the front surface 30A and the rear surface 30B of the flexible display module 30, and may refer to a recessed or recessed portion in the first side surface 301. The second notch 820 may be, for example, a second opening penetrating between the front surface 30A and the rear surface 30B of the flexible display module 30, and may refer to a recessed or recessed portion in the second side surface 302.

[0069] According to an embodiment, when viewed from above the front surface 30A of the flexible display module 30 in its unfolded state, the first notch 810 and the second notch 820 can be formed symmetrically to each other. For example, the first depth D1 into which the first notch 810 is cut along the direction from the first side surface 301 to the second side surface 302 can be substantially the same as the second depth D2 into which the second notch 820 is cut along the direction from the second side surface 301 to the first side surface 301.

[0070] According to an embodiment, the screen portion 71 of the flexible display module 30 may include a first region ①, a second region ②, and a third region ③ located between the first region ① and the second region ③. The first region ① may include a portion of the screen portion 71 corresponding to the first notch 810. The first region ① may include a first display area (not shown) of the display area 31. The first region ① may include a first edge 811 positioned between the first region ① and the first notch 810. The first edge 811 may form the inner surface of the first notch 810.

The second region ② may include a second edge 821 positioned between the second region ③ and the second notch 820. The second edge 821 may form the inner surface of the second notch 820. The first edge 811 and the second edge 821 may be parallel to the third boundary B3 of the display area 31. When viewed from above the front surface 30A of the flexible display module 30 in its unfolded state, the distance between the first edge 811 and the third boundary B3 can be the same as the distance between the second edge 821 and the third boundary B3. The third region ③ can be connected to the neck 72 and can include a third display region (not shown) within the display region 31. In one embodiment, when viewed from above the front surface 30A of the flexible display module 30 in its unfolded state, the first display region included in the first region ① and the second display region included in the second region ② can be arranged symmetrically to each other, with the third display region included in the third region ③ situated between the first and second display regions.

[0071] According to an embodiment, when the flexible display module 30 is pulled out of the housing 20 so that the display area 31 is fully exposed to the outside, the neck 72 is positioned at the opening 204 of the housing 20 (see embodiment 204). Figure 3 When the flexible display module 30 is pulled out of the housing 20 so that the display area 31 is fully exposed to the outside, the first edge 811 can be located outside the housing 20, and the first area ① of the flexible display module 30 can be placed in the following state: the first area ① can be positioned along a direction perpendicular to the first axis C (e.g., Figure 2 or Figure 3 The flexible display module 30 bends along the y-axis direction without interference from the housing 20. When the flexible display module 30 is pulled out of the housing 20 so that the display area 31 is fully exposed to the outside, the second edge 821 can be outside the housing 20, and the second area ② of the flexible display module 30 can be placed in a second state in which the second area ② can be along a direction perpendicular to the first axis C (e.g., along the y-axis direction) without interference from the housing 20. Figure 2 or Figure 3 The y-axis direction of the shell is bent without being interfered with by the shell 20.

[0072] Figure 6 An electronic device 2 in a second state according to an embodiment is shown, in which the screen portion 71 of the flexible display module 30 is pulled out of the housing 20. Figure 7 According to the embodiments Figure 6 The example shows a planar diagram of electronic device 2 in the xy plane. (Reference) Figure 6 and Figure 7 By applying external force to the handle 90, the flexible display module 30 can be pulled out from the inside of the housing 20, and the electronic device 2 can be pulled out from the handle 90. Figure 2 The first state transforms into Figure 6 The second state can refer to the state where the flexible display module 30 is pulled out of the housing 20 to its maximum extent, such that the display area 31 no longer expands and is arranged in a substantially planar shape. For example, due to the elasticity of the flexible display module 30, the screen portion 71 pulled out of the housing 20 can be configured to be substantially flat. In one embodiment, when the external force pulling the flexible display module 30 out of the housing 20 is removed, the electronic device 2 can be released from... Figure 6 The second state transforms into Figure 2 The first state. For example, electronic device 2 may include a drive module operatively connected to the cylindrical roller 40 or the flexible display module 30, and the drive module may maintain the force that introduces the flexible display module 30 into the internal space of housing 20. The drive module may include an elastic structure using an elastic member such as a torsion spring. The elastic structure may elastically maintain the force used to introduce the flexible display module 30 into the internal space of housing 20. When the external force that pulls the flexible display module 30 out of housing 20 disappears, electronic device 2 may be released from the housing 20 due to the drive module. Figure 6 The second state transforms into Figure 2 The first state (automatic transition).

[0073] refer to Figure 2 and Figure 3 In one embodiment, when the flexible display module 30 is pulled out of the housing 22, causing the display area 31 to be fully exposed, the first bending mechanism 50 can bend the first area ① of the flexible display. The first bending mechanism 50 may include, for example, a first rotating member 51 and a first driving portion 52 (e.g., a first driving unit or a first driving module) connected to the first rotating member 51. The first rotating member 51 can be rotated by the first driving portion 52 to press and bend the first area ① of the flexible display module 30. Figure 6In the second state shown, the first rotating member 51 can be positioned to rotatably press the portion included in the first region ① of the rear surface 30B of the flexible display module 30. In one embodiment, the shaft 521 of the first drive portion 52 located inside the housing 20 can pass through a hole formed in the housing 20 and be connected to the first rotating member 51 located outside the housing 20 by means of screws (or bolts) 53. The first rotating member 51 can rotate when the first drive portion 52 rotates the shaft 521. When the display area 31 is fully pulled out of the housing 20 through the opening 204, the second bending mechanism 60 can bend the second region ② of the flexible display module 30 corresponding to the second notch 520. The second bending mechanism 60 can be implemented in substantially the same manner as the first bending mechanism 50 and can include, for example, the second rotating member 61 and a second drive portion (e.g., a second drive unit or a second drive module) connected to the second rotating member 61. The first rotating member 51 can rotate about a third axis C3, and the second rotating member 61 can rotate about a fourth axis C4 spaced apart from the third axis C3. The third axis C3 and the fourth axis C4 can be perpendicular to the first axis C1. The printed circuit board 70, located inside the housing 20, can be electrically connected to the first drive section 52 and the second drive section via electrical paths such as those of a flexible printed circuit board. When the display area 31 is fully pulled out of the housing 20 through the opening 204, the control circuitry (e.g., ...) provided on the printed circuit board 70... Figure 1 The processor 120 in the process can: control the first bending mechanism 50 so that the first region ① of the flexible display module 30 can be bent; and / or control the second bending mechanism 60 so that the second region ② of the flexible display module 30 can be bent. The first drive section 52 may include a motor operably connected to the shaft 521, and a motor drive circuit (e.g., a motor controller or motor driver) electrically connected to the motor. The motor drive circuit may be based on the processor (e.g., ... Figure 1 The processor 120 receives control signals to control the motor. The motor drive circuit may include a motor encoder for detecting the drive state of the motor. For example, the motor encoder may include: a disk coupled to the rotating shaft of the motor; and a detector capable of detecting the direction of rotation, rotation angle, amount of rotation, rotational speed, rotational acceleration, or rotational angular velocity of the rotating shaft by marking electronically identifiable scales and markings on the disk. The processor may base its control on signals stored in memory (e.g., ...). Figure 1 The instructions in the memory 130 are used to control the motor drive circuit. The second drive section included in the second bending mechanism 60 can be implemented in substantially the same manner as the first drive section. The control circuit (e.g., electrically connected to the first drive section 52 and the second drive section) is used to control the motor drive circuit. Figure 1The processor 120 can identify the following state by using various sensors (e.g., accelerometer, geomagnetic sensor, optical sensor, magnetic detection sensor) or various current-carrying structures (e.g., electrical contacts): that is, the flexible display module 30 is pulled out of the housing 20, so that the display area 31 is fully exposed to the outside.

[0074] Figure 8 An electronic device 2 in a third state according to an embodiment is shown, in which the screen portion 71 of the flexible display module 30 pulled out from the housing 20 is configured to be bent. Figure 9 According to the embodiments Figure 8 The example shows a planar diagram of electronic device 2 in the xy plane. (Reference) Figure 8 and Figure 9 The electronic device 2 can rotate from the first rotating member 51 and the second rotating member 61. Figure 6 The second state transforms into Figure 8 The third state can refer to the following state: the flexible display module 30 is pulled out of the housing 20 to its maximum extent so that the display area 31 no longer expands, and the display area 31 is set to a curved shape. In the third state, the screen portion 71 of the flexible display module 30 can be positioned relative to the first axis C1 ( Figure 2 or Figure 6 The second axis C2 (see) Figure 6 and Figure 8 (For example, a curved axis) bends. The second axis C2 may be a virtual line passing through the center of the display area 31. For example, when viewed from above the front surface 30A of the flexible display module 30 in its unfolded state (see...) Figure 5 The distance between the second axis C2 and the first boundary B1 can be substantially the same as the distance between the second axis C2 and the second boundary B2. In one embodiment, in the third state, interference between the first edge 811 and the housing 20 and / or interference between the second edge 821 and the housing 20 can prevent the screen portion 71 of the flexible display module 30 from being introduced into the internal space of the housing 20. In one embodiment, when the first region ① of the screen portion 71 is bent by the first rotating member 51 and the second region ② of the screen portion 71 is bent by the second rotating member 61, force can be transmitted to the third region ③ in the screen portion 71, and the third region ③ can be bent about the second axis C2 to be smoothly aligned with the first region ① and the second region ②. Reference Figure 3 The opening 204 of the housing 20 may have space that allows the third region ③ to bend. For example, the second distance L2 between the third inner surface 204C and the fourth inner surface 204D of the opening 204 may be formed corresponding to the bending of the third region ③.

[0075] According to the embodiment, when the first region ① of the screen portion 71 is bent by the first rotating member 51 and the second region ② of the screen portion 71 is bent by the second rotating member 61, the screen portion 71 can be bent in a specific bending shape in the direction of the second axis C2 due to the transmission of force or motion. For example, the second end 312 of the screen portion 71 can be bent in a bending shape that is substantially the same as the portion 313 of the screen portion 71 pressed by the first rotating member 51 and the second rotating member 61.

[0076] According to one embodiment, when the first region ① of the screen portion 71 is bent by the first rotating member 51 and the second region ② of the screen portion 71 is bent by the second rotating member 61, a rigid structure responsive to the elasticity of the screen portion 71 can be implemented. This rigid structure can facilitate bending the screen portion 71 in a specific bending shape in the direction of the second axis C2. For example, the support structure included in the flexible display module 30 (e.g., Figure 12 or Figure 13 The display support structure 1130 may include one or more inner cores extending along the direction of the second axis C2. In one embodiment, reference... Figure 3 The first inner core can be positioned in the non-display area 32 corresponding to the first side surface 301, and the second inner core can be positioned in the non-display area 32 corresponding to the second side surface 302.

[0077] In one embodiment, a separate fixing member (or support member) can be implemented that can be connected to the second end 312 of the screen portion 71. The fixing member (e.g., a cap) can help ensure that the second end 312 can maintain substantially the same curved shape as the portion 313 of the screen portion 71 pressed by the first rotating member 51 and the second rotating member 61.

[0078] According to an embodiment, when a signal (e.g., a signal from a hardware button or software button on a screen) is generated by an input device included in electronic device 2, electronic device 2 can... Figure 8 The third state via Figure 6 The second state transforms into Figure 2 The first state. In a particular embodiment, when a signal is generated from various sensors such as a pressure sensor, the electronic device 2 can... Figure 8 The third state via Figure 6 The second state transition to Figure 2 The first state. For example, when the first rotating member 51 and the second rotating member 61 return to the first state as the initial state (see...). Figure 2 When the flexible display module 30 is in operation, the screen portion 71 can return to a flat state due to its elasticity and can be introduced into the internal space of the housing 20 due to the drive module (e.g., an elastic structure).

[0079] refer to Figure 5 In one embodiment, the flexible display module 30 may include a first reinforcing member (or protective member) 910 disposed in a first recess 710. The first reinforcing member 910 may be disposed at least partially along the surface of the first recess 810. The first reinforcing member 910 may reduce the decrease in the flexibility of the flexible display module 30. The first reinforcing member 910 may include, for example, a coating. In a particular embodiment, the first reinforcing member 910 may include a film bonded using an adhesive material. In a particular embodiment, the first reinforcing member 910 may be fabricated separately and disposed or attached to the first recess 810. The first reinforcing member 910 may include, for example, a metal or a polymer. When force or motion is transmitted to the flexible display module 30, the first reinforcing member 910 may help prevent damage to the flexible display module 30 by reducing the stress generated in the first recess 810 or the neck 72. The flexible display module 30 may include a second reinforcing member (or second protective member) 920 disposed in a second recess 820, and the second reinforcing member 920 may be formed in substantially the same manner as the first reinforcing member 910 for the first recess 810. When force or motion is transmitted to the flexible display module 30, the second reinforcing member 920 can help prevent damage to the flexible display module 30 by reducing the stress generated in the second notch 820 or the neck 72.

[0080] refer to Figure 2 Electronic device 2 can be, for example Figure 1 The electronic device 101 may include or may include the electronic device 101 contained in Figure 1 At least one component from the components (e.g., processor 120, memory 130, input module 150, sound output module 155, display module 160, audio module 170, sensor module 176, interface 177, connection terminal 178, haptic module 179, camera module 180, power management module 188, battery 189, communication module 190, user identification module 196, and antenna module 197) in the electronic device 101. In a particular embodiment, Figure 1Some components shown may be omitted from electronic device 2, or other components may be additionally included in electronic device 2. The location or number of components included in electronic device 2 may vary and is not limited to the examples shown. At least one component may be disposed on printed circuit board 70, or electrically connected to printed circuit board 70 via an electrical path (e.g., flexible printed circuit board or cable). For example, electronic device 2 may include a support structure (or support member) 205 positioned between printed circuit board 70 and battery 80 inside housing 20, and printed circuit board 70 and battery 80 may be electrically connected via various current-carrying structures (e.g., current-carrying via flexible printed circuit board, or current-carrying via physical contacts). As a portion inside housing 20 on which components (e.g., brackets or mounting plates) are arranged, support structure 205 may contribute to the durability or rigidity (e.g., torsional strength) of electronic device 2. Support structure 205 may be attached to housing 20 or may be integrally formed with at least a portion of housing 20, and may comprise metal and / or polymer. As another example, portion 206 of housing 20 may be electrically connected to a wireless communication module disposed on printed circuit board 70 (e.g., wireless communication module). Figure 1 The wireless communication module 192 in the middle can also be operated as an antenna radiator.

[0081] According to a specific embodiment (not shown), the battery 80 may be located within the internal space of the flexible display module 30, which is wound up. For example, the cylindrical roller 40 may include a cylindrical outer surface and a cylindrical inner surface, with the flexible display module 30 positioned on the cylindrical outer surface in a wound state, and the cylindrical inner surface positioned on the opposite side of the cylindrical outer surface. The cylindrical roller 40 may be hollow, for example, extending from a first opening on one side to a second opening on the other side. The cylindrical roller 40 may include a first cover covering the first opening and rotatably connected to the housing 20, and a second cover covering the second opening and rotatably connected to the housing 20. The battery 80 may be located within the internal space (e.g., hollow) of the cylindrical roller 40, which is defined by the cylindrical inner surface of the cylindrical roller. The cylindrical roller 40 may be referred to by various other terms, such as a hollow cylinder or a cylindrical shell. The cylindrical inner surface may have a shape corresponding to the internal space of the cylindrical roller 40 in which the battery 80 is housed. For example, the battery 80 may be cylindrical, and the cylindrical inner surface of the cylindrical roller 40 may be parallel to the cylindrical outer surface of the battery 80 or the cylindrical outer surface of the cylindrical roller 40. The cylindrical inner surface of the cylindrical roller 40 is not limited to a circular surface and may be formed into various other shapes capable of supporting the battery 80. In one embodiment, the battery 80 may rotate together with the cylindrical roller 40 when the flexible display module 30 is introduced into or pulled out of the housing 20 through the opening 204. For example, the battery 80 may be fitted into the internal space of the cylindrical roller 40, and a rotating body comprising the cylindrical roller 40 and the battery 80 may be formed. As another example, an adhesive material may be positioned between the battery 80 and the cylindrical roller 40, and a rotating body comprising the cylindrical roller 40 and the battery 80 may be formed. In one embodiment, the rotating body comprising the cylindrical roller 40 and the battery 80 may be achieved by balancing the weight around a first axis C1. This weight balance centered on the first axis C1 can reduce the vibration generated in the electronic device 2 when the rotating body, including the columnar roller 40 and the battery 80, rotates about the first axis C1.

[0082] Figure 10 It is included according to another embodiment Figure 2 A plan view of the flexible display module 30 in the unfolded state in the electronic device 2.

[0083] refer to Figure 10 In one embodiment, with Figure 5Compared to the example, the flexible display module 30 can be implemented such that the neck 1030 extends while replacing or reducing the size of the third portion 73. In one embodiment, the flexible display module 30 may include a first reinforcing member (or a first protective member) 1041 disposed along the first side surface 301 corresponding to the first edge 811 and the neck 1030. The flexible display module 30 may include a second reinforcing member (or a second protective member) 1042 disposed along the second side surface 302 corresponding to the second edge 821 and the neck 1030. The first reinforcing member 1041 and / or the second reinforcing member 1042 may be implemented to reduce the decrease in flexibility of the flexible display module 30. The first reinforcing member 1041 and / or the second reinforcing member 1042 may include, for example, a coating. In a particular embodiment, the first reinforcing member 1041 and / or the second reinforcing member 1042 may include a film bonded using an adhesive material. In a particular embodiment, the first reinforcing member 1041 and / or the second reinforcing member 1042 may be fabricated separately and disposed or coupled to the flexible display module 30. The first reinforcing member 1041 and / or the second reinforcing member 1042 may comprise, for example, metal or polymer. The first reinforcing member 1041 (e.g., a coating) can help prevent damage to the flexible display module 30 by reducing the stress generated in the first edge 811 or neck 1030 when force or motion is transmitted to the flexible display module 30. The second reinforcing member 1042 (e.g., a coating) can help prevent damage to the flexible display module 30 by reducing the stress generated in the second edge 821 or neck 1030 when force or motion is transmitted to the flexible display module 30.

[0084] Figure 11 An example is shown. Figure 3 The cross-sectional structure of the flexible display module 30 is 1100. Figure 12 A display support structure 1130 according to an embodiment is shown.

[0085] refer to Figure 11 and Figure 12 In an embodiment, the flexible display module (or flexible display component) 30 may include a flexible display 1110, a support sheet 1120, a display support structure 1130 and / or a back cover 1140.

[0086] According to an embodiment, the display support structure 1130 can SettingsThe flexible display 1110 is attached to or on the rear surface of the flexible display 1110. The display support structure 1130 can, for example, allow the flexible display 1110 to be movable while maintaining a smoothly connected shape. In one embodiment, the display support structure 1130 may include a multi-bar structure (or, multi-bar assembly). In one embodiment, the display support structure (e.g., multi-bar structure) 1130 may include a first layer 1131 and a second layer 1132 including a plurality of support bars (or, multiple support bars) 1132a. The first layer 1131 may be positioned between the support sheet 1120 and the second layer 1132. The first layer 1131 may be in the form of a flexible film or sheet. The plurality of support bars 1132a may be along a first axis C1 (reference...). Figure 2 and Figure 3 The support rods 1132a extend in the direction of extension (e.g., the x-axis direction). The plurality of support rods 1132a may have substantially the same cross-sectional shape and may be arranged at a specific spacing from each other. In a particular embodiment, some of the support rods 1132a may be arranged at a first spacing, and others may be arranged at a second spacing different from the first spacing. The display support structure 1130 can be flexible due to the separate arrangement of the plurality of support rods 1132a on the first layer 1131 and the flexibility of the first layer 1131. The first layer 1131 may include a first region in which the plurality of support rods 1132a are disposed, and a second region between the first regions. The display support structure 1130 can be bent significantly due to the second region. The plurality of support rods 1132a may have a cross-sectional shape (e.g., a trapezoidal shape) that narrows along a direction from the front surface 30A of the flexible display module 30 to the rear surface 30B of the flexible display module 30. This cross-sectional shape can facilitate bending the display support structure 1130 with a smaller bending radius. The cross-sectional shapes of the multiple support rods 1132a can be varied and are not limited to the embodiments shown.

[0087] According to an embodiment, the first layer 1131 and the second layer 1132 may comprise the same material. For example, the first layer 1131 and the second layer 1132 may be integrally formed. As another example, the display support structure 1130 can be implemented by separately forming the first layer 1131 and the second layer 1132 and then combining them together.

[0088] According to a particular embodiment, the first layer 1131 and the second layer 1132 may comprise different materials. Compared to the first material included in the first layer 1131, the second material included in the second layer 1132 may have greater strength or greater stiffness (or stiffness characteristics).

[0089] According to an embodiment, the first layer 1131 and the second layer 1132 may include metallic materials. For example, the first layer 1131 and the second layer 1132 may include the same metallic material. As another example, the first layer 1131 may include a first metallic material, and the second layer 1132 may include a first metallic material and a second metallic material. The first metallic material of the first layer 1131 may include a material having a bonding affinity with the support sheet 1120 and the second metallic material of the second layer 1132.

[0090] According to a specific embodiment, the first layer 1131 may include a first polymer, and the second layer 1132 may include a second polymer different from the first polymer. The first polymer included in the first layer 1131 may have greater flexibility (or flexibility properties) than the second polymer included in the second layer 1132. The first polymer may be a variety of materials, such as polyester (PET), polyimide (PI), or thermoplastic polyurethane (TPU). The first polymer may contribute to the bonding strength between the support sheet 1120 and the second layer 1132, and contribute to the durability of the display support structure 1130. The first polymer may include a material having bonding affinity with the second polymer of the support sheet 1120 and the second layer 1132. The first layer 1131 may be formed to have a thickness that ensures the bending properties of the display support structure 1130, depending on the flexibility properties of the first polymer. The second polymer included in the second layer 1132 may have higher strength or higher stiffness (or stiffness properties) than the first polymer included in the first layer 1131. The second polymer may include, for example, engineering plastics (e.g., polycarbonate (PC) or polymethyl methacrylate (PMMA)). As another example, the second polymer may include a material obtained by mixing engineering plastics with various reinforcing materials such as glass fibers or carbon fibers (e.g., fiber reinforced plastic (FRP)).

[0091] According to a particular embodiment, the first layer 1131 may comprise a polymer, while the second layer 1132 may comprise a metallic material. In this case, to increase the mechanical bonding force between the first layer 1131 and the second layer 1132, a connecting structure (e.g., an anchoring effect) may be included, in which a portion of the first layer 1131 is positioned in a hole or groove formed in the second layer 1132.

[0092] According to a particular embodiment, a track portion for guiding the movement of the flexible display module 30 can be implemented. The track portion may include, for example, a first guide rail (not shown) and a second guide rail (not shown), with the first guide rail connected to one end 1201 of a plurality of support rods 1132a (see...). Figure 12 Correspondingly formed in the shell 20 (see Figure 2In the housing 20, a second guide rail is formed corresponding to the other end (not shown) of one of the plurality of support rods 1132a. The first and second guide rails may include grooves or recesses corresponding to the movement path of the display support structure. One end 1201 of the plurality of support rods 1132a may be positioned in or inserted into the first guide rail, and the other end (not shown) of the plurality of support rods 1132a may be positioned in or inserted into the second guide rail. The display support structure can move while being guided by the first and second guide rails. In a particular embodiment, a rotating member (e.g., a rolling member such as a bearing) may be provided on one end 1201 and the other end of the plurality of support rods 1132a.

[0093] According to an embodiment, a support sheet 1120 may be disposed on or attached to the rear surface of the flexible display 1110. The support sheet 1120 can contribute to the durability of the flexible display 1110. The support sheet 1120 can reduce the impact of loads or stresses that may occur when the flexible display module 30 moves on the flexible display 1110. The support sheet 1120 can prevent damage to the flexible display 1110 from forces transmitted when the flexible display 1110 moves. The support sheet 1120 may include a lattice structure. The lattice structure may include, for example, multiple openings (or slits). For example, the multiple openings may be formed periodically and may have substantially the same shape and may be repeatedly arranged at regular intervals. The lattice structure can contribute to the flexibility of the flexible display 1110. In a particular embodiment, the support sheet 1120 may include a groove pattern (not shown) with multiple grooves instead of a lattice structure. In a particular embodiment, the support sheet 1120 or corresponding conductive member including a lattice structure or groove pattern may be formed as a multilayer. In a particular embodiment, the first layer 1131 of the display support structure 1130 may be omitted, and in this case, the support piece 1120 may replace the first layer 1131. In a particular embodiment, the display support structure 1130 or the first layer 1131 may be used as the support piece 1120, and in this case, the support piece 1120 may be omitted.

[0094] In one embodiment, reference Figure 8 When the first region ① of the screen portion 71 is bent by the first rotating member 51 and the second region ② of the screen portion 71 is bent by the second rotating member 61, the support piece 1120 can help allow the screen portion 71 to bend in a specific bending shape in the direction of the second axis C2 in response to the elasticity of the screen portion 71.

[0095] According to an embodiment, the flexible display 1110 can be attached to the transparent cover 1115 using an optically transparent adhesive member 1116 (e.g., optically transparent adhesive (OCA), optically transparent resin (OCR), or optically elastic resin (SVR)). The transparent cover 1115 (e.g., a window) can protect the flexible display 1110 from external influences by covering it. The transparent cover 1115 can be implemented in the form of a flexible film (e.g., a film layer). The transparent cover 1115 can include, for example, a plastic film (e.g., a polyimide film) or a thin-film glass (e.g., ultra-thin glass). In a particular embodiment, the transparent cover 1115 can include multiple layers. For example, the transparent cover 1115 can have various coatings disposed on the plastic film or thin-film glass. For example, the transparent cover 1115 can have at least one protective layer or coating containing a polymer material (e.g., polyester (PET), polyimide (PI), or thermoplastic polyurethane (TPU)) disposed on the plastic film or thin-film glass.

[0096] The flexible display 1110 may include, for example, a display panel 1111, a base film 1112, a lower panel 1113, or an optical layer 1114. The display panel 1111 may be positioned between the optical layer 1114 and the base film 1112. The base film 1112 may be positioned between the display panel 1111 and the lower panel 1113. The optical layer 1114 may be positioned between an optically transparent adhesive member 1116 and the display panel 1111. Various polymer adhesive members (not shown) may be arranged between the display panel 1111 and the base film 1112, between the base film 1112 and the lower panel 1113, and / or between the display panel 1111 and the optical layer 1114. The display panel 1111 may include, for example, a light-emitting layer 1111a, a thin-film transistor (TFT) film 1111b, and / or an encapsulation layer (e.g., a thin-film encapsulation (TFE)) 1111c. The light-emitting layer 1111a may include multiple pixels implemented using light-emitting elements such as OLEDs or micro-LEDs. The light-emitting layer 1111a may be deposited on a TFT film 1111b by vapor deposition of an organic material. The TFT film 1111b may be positioned between the light-emitting layer 1111a and the base film 1112. The TFT film 1111b may refer to a film structure in which at least one TFT is disposed on a flexible substrate (e.g., a PI film) through a series of processes such as deposition, patterning, and etching. At least one TFT may control the current to the light-emitting element of the light-emitting layer 1111a to turn the pixel on or off or adjust the brightness of the pixel. This at least one TFT may be implemented using, for example, an amorphous silicon (a-Si) TFT, a liquid crystal polymer (LCP) TFT, a low-temperature polycrystalline oxide (LTPO) TFT, or a low-temperature polycrystalline silicon (LTPS) TFT. The display panel 1111 may include a storage capacitor, which may hold the voltage signal in the pixel, maintain the voltage applied to the pixel for one frame, or reduce the variation in the gate voltage of the TFT due to leakage current during the light-emitting time. Through routine procedures (e.g., initialization, data writing) used to control at least one TFT, the storage capacitor can maintain the voltage applied to the pixel at preset time intervals. In one embodiment, the display panel 1111 can be implemented based on an OLED, and the encapsulation layer 1111c can cover the light-emitting layer 1111a. Since the organic materials and electrodes emitting light in an OLED are highly sensitive to oxygen and / or moisture and may lose their light-emitting properties, the encapsulation layer 1111c can seal the light-emitting layer 1111a to prevent oxygen and / or moisture from penetrating into the OLED. The base film 1112 can comprise a flexible film made of a polymer or plastic such as polyimide or polyester (PET). The base film 1112 can be used to support and protect the display panel 1111. In certain embodiments, the base film 1112 may be referred to as a protective film, back film, or backplate.

[0097] The lower plate 1113 may include multiple layers for various functions. Adhesive components (not shown) of various polymers may be disposed between the multiple layers included in the lower plate 1113. The lower plate 1113 may include, for example, a light-shielding layer 1113a, a buffer layer 1113b, or a lower layer 1113c. The light-shielding layer 1113a may be positioned between the base film 1112 and the buffer layer 1113b. The buffer layer 1113b may be positioned between the light-shielding layer 1113a and the lower layer 1113c. The light-shielding layer 1113a may at least partially block light incident from the outside. For example, the light-shielding layer 1113a may include an embossed layer. The embossed layer may be a black layer including an embossed pattern. The buffer layer 1113b may mitigate external impacts applied to the flexible display 1110. For example, the buffer layer 1113b may include a sponge layer or a padding layer. The lower layer 1113c may diffuse, disperse, or dissipate within the electronic device 2 (reference). Figure 2 The lower layer 1113c can absorb or shield electromagnetic waves. The lower layer 1113c can mitigate external impacts applied to the electronic device 2 or the flexible display 1110. For example, the lower layer 1113c may include a composite sheet 1113d or a conductive sheet 1113e. In one embodiment, the composite sheet 1113d may be a sheet processed by combining layers or sheets with different properties. For example, the composite sheet 1113d may include at least one of polyimide or graphite. The composite sheet 1113d may be replaced by a single sheet comprising a material (e.g., polyimide or graphite). The composite sheet 1113d may be positioned between the buffer layer 1113b and the conductive sheet 1113e. The conductive sheet 1113e can be used to shield the flexible display 1110 from electromagnetic interference (EMI). The conductive sheet 1113e may include various different metallic materials (e.g., copper). In certain embodiments, at least a portion of the lower layer 1113c, which serves as a conductive component (e.g., a metal plate), can help enhance the rigidity of the flexible display module 30, shield ambient noise, and dissipate heat emitted from surrounding heat dissipation components (e.g., display driving circuitry (e.g., DDI)). The conductive component may include at least one of, for example, copper (Cu), aluminum (Al), stainless steel (SUS), or CLAD (e.g., a laminated component with alternating SUS and Al). The lower layer 1113c may include various layers for various other functions. According to various embodiments (not shown), at least one additional polymer layer (e.g., a layer comprising PI, PET, or TPU) in addition to the base film 1112 may be disposed on the rear surface of the display panel 1111. In various embodiments, at least one of the multiple layers included in the lower plate 1113 (e.g., light-shielding layer 1113a, buffer layer 1113b, composite sheet 1113d, and conductive sheet 1113e) may be omitted. In various embodiments, the arrangement order of the multiple layers included in the lower plate 1113 may vary and is not limited to these embodiments. Figure 11 Examples of implementations.

[0098] Optical layer 1114 may include, for example, a polarizing layer (or polarizer) or a phase retardation layer (or retarder). The polarizing layer and phase retardation layer can improve the outdoor visibility of the screen. Optical layer 1114 can selectively transmit light generated from a light source, such as display panel 1111, and vibrate in a specific direction. In a particular embodiment, a layer in which the polarizing layer and phase retardation layer are combined may be provided, and this layer may be defined as a "circular polarizing layer". Optically transparent adhesive member 1116 may be positioned between transparent cover 1115 and optical layer 1114. In a particular embodiment, the polarizing layer (or circular polarizing layer) may be omitted, and in this case, a black pixel definition layer (PDL) and / or a color filter may be included instead of the polarizing layer. Electronic device 2 (reference) Figure 2 The display panel 1111 may include touch sensing circuitry (e.g., a touch sensor) (not shown). The touch sensing circuitry can be implemented using a transparent conductive layer (or film) based on various conductive materials such as indium tin oxide (ITO). In a particular embodiment, the touch sensing circuitry may be disposed between the transparent cover 1115 and the optical layer 1114 (e.g., add-on type). In another embodiment, the touch sensing circuitry may be disposed between the optical layer 1114 and the display panel 1111 (e.g., on-cell type). In yet another embodiment, the display panel 1111 may include touch sensing circuitry or touch sensing functionality (e.g., in-cell type). In a particular embodiment, the display panel 1111 may be based on an OLED and may include an encapsulation layer 1111c disposed between the light-emitting layer 1111a and the optical layer 1114. The encapsulation layer 1111c may serve as a pixel protection layer for protecting multiple pixels of the light-emitting layer 1111a. In one embodiment (not shown), the flexible display 1110 may include a conductive pattern, such as a metal mesh (e.g., an aluminum mesh), as a touch sensing circuit within the encapsulation layer 1111c between the encapsulation layer 1111c and the optical layer 1114. For example, in response to bending of the flexible display 1110, the metal mesh may have higher durability than a transparent conductive layer implemented with ITO. In a particular embodiment, the flexible display 1110 may also include a pressure sensor (not shown) capable of measuring touch intensity (pressure). The multiple layers, stacking structures, or stacking orders included in the display panel 1111 or the lower panel 1113 can be varied. The flexible display 1110 may be implemented by omitting some components or adding others, depending on the form of provision of flexible displays or convergence trends.

[0099] According to an embodiment, the back cover 1140 may be flexible and may form the rear surface 30B of the flexible display module 30. The back cover 1140 may make at least one component of the flexible display module 30 (e.g., the display support structure 1130) substantially invisible to the rear surface 30B. For example, the back cover 1140 may be formed to be substantially opaque. In one embodiment, the back cover 1140 may be attached to the display support structure 1130 using an adhesive material. In a particular embodiment, to ensure the flexibility of the flexible display module 30 or to reduce stress generated in at least one component included in the flexible display module 30 when bent, the back cover 1140 and the display support structure 1130 may be configured to be in a non-attached state. In a particular embodiment, a lubricant (e.g., grease) may be positioned between the back cover 1140 and the display support structure 1130. In a particular embodiment, the back cover 1140 may be omitted.
