Description

Electronic devices containing protective films

[0001] One embodiment disclosed in this document relates to an electronic device including a protective film.

[0002] Displays can play a key role in portable electronic devices. They can visually display information. Factors such as display design, size, and quality can significantly influence consumers' choice of electronic devices.

[0003] Recent advancements in display technology have led to the introduction of flexible displays into the market. These flexible displays can also be used to create displays with variable screen sizes. For example, electronic devices are being developed that include displays that can be expanded or contracted through sliding, or displays that can be rolled onto a specific structure. For example, an electronic device may have a structure (e.g., a rollable or slideable structure) that allows the display area of ​​a flexible display to be varied through the support of housings that slide relative to each other.

[0004] A rollable electronic device may include a plurality of housings that move relative to each other when slid-in or slid-out. A flexible display may be disposed in the plurality of housings, and a display area may be reduced or expanded when the plurality of housings slide. For example, the flexible display may include a flat portion that is always visible from the outside, and a bending portion that extends from the flat portion and is at least partially bent so as to be retracted into an internal space of the electronic device so as not to be visible from the outside in a slide-in state. The bending portion may be partially bent in a slide-in or slide-out state. Additionally, the bending portion may be pulled out from the internal space of the electronic device when the electronic device is in a slide-out state to form a substantially flat surface with the flat portion.

[0005] A protective film may be attached to the outermost layer of the flexible display. The protective film is provided in a replaceable form, and a portion of it may be bent along the bending portion of the flexible display and inserted into the internal space of the electronic device.

[0006] Meanwhile, the outermost layer of the flexible display may be composed of glass and / or a coating. In such a case, the adhesive strength of the protective film to the flexible display may be low, resulting in the protective film peeling off from the flexible display. The protective film is a replaceable component of the flexible display. Therefore, the protective film cannot be fixedly attached to the flexible display so as to be detachable from the flexible display.

[0007] According to one embodiment of the present disclosure, a structure can be proposed that alleviates or reduces the phenomenon of a protective film being peeled off from a flexible display.

[0008] According to one embodiment of the present disclosure, an electronic device may include a first housing, a second housing movably coupled to the first housing, a flexible display including an internal region disposed in the first housing and the second housing and at least a portion of which moves in an internal space of the electronic device based on movement of the second housing relative to the first housing, a support bar including a first support portion supporting an end of the flexible display located in the internal space of the electronic device and a second support portion extending from the first support portion and adjacent to an end of the flexible display, and a protective film including a first attachment region adhered to the flexible display and a second attachment region extending from the first attachment region and at least a portion of which faces the second support portion.

[0009] According to one embodiment of the present disclosure, a peeling phenomenon of the protective film on the flexible display can be reduced or mitigated by attaching a portion of the protective film to a structure having a higher surface roughness than the outermost layer of the flexible display. In one embodiment, the protective film can be formed to be longer than the flexible display in the sliding direction of the electronic device. In this case, an end of the protective film can be spaced apart from an end of the flexible display located inside the electronic device. The end of the protective film can be attached to a structure having a higher surface roughness than the outermost layer of the flexible display and spaced apart from the end of the flexible display in the internal space of the electronic device. Therefore, a phenomenon of the protective film peeling from the flexible display can be mitigated or reduced.

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)).

[0035] 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 operations.

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

[0036] 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.

[0050] 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).

[0051] 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) can 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.

[0052] 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, for example, by the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device via the at least one selected 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).

[0053] 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.

[0054] 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)).

[0055] 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.

[0085] In describing the electronic device (200) of FIGS. 5A to 5C, the same reference numerals are given to components that are substantially the same as those of the electronic device (200) of FIG. 4, and a detailed description thereof may be omitted.

[0086] Referring to FIGS. 5A to 5C, the electronic device (200) may include a first housing (210) having a first space (2101), a second housing (220) having a second space (2201), a support member (240) connected to the second housing (220) and at least partially accommodated in the first space (2101) in a slide-in state, a flexible display (230) arranged to be supported by at least a portion of the support member (240) and at least a portion of the second housing (220), and a drive motor (260) arranged in the first space (2101) and including a pinion gear (e.g., a pinion gear (261) of FIG. 4) gear-coupled with a rack gear (e.g., a rack gear (228) of FIG. 4) of the second space (2201). In one embodiment, the drive motor (260) can automatically move the second housing (220) in a slide-in direction (② direction) or a slide-out direction (① direction) with respect to the second housing (210) through gear engagement of a pinion gear (e.g., pinion gear (261) of FIG. 4) and a rack gear (2121) (e.g., rack gear (228) of FIG. 4).

[0087] According to one embodiment, at least a portion of the second housing (220) may be accommodated in the first space (2101) of the first housing (210) in the slide-in state of the electronic device (200) (state of FIG. 5a). In one embodiment, at least a portion of the flexible display (230) may be accommodated in a manner of being bent into the first space (2101) together with the support member (240), thereby being arranged so as not to be visible from the outside. In this case, the flexible display (230) may have a first display area (e.g., a display area corresponding to the first portion (230a) of FIG. 3a) exposed to the outside.

[0088] According to one embodiment, the electronic device (200) can transition from an intermediate state (state of FIG. 5b) to a slide-out state (state of FIG. 5c) by controlling the driving of the drive motor (260). In some embodiments, the electronic device (200) can be set to stop in a designated intermediate state between the slide-in state and the slide-out state (free stop function). In some embodiments, the electronic device (200) can transition to the slide-in state, the intermediate state, or the slide-out state through a user's operation in a state where no driving force is provided to the drive motor (260).

[0089] According to one embodiment, at least a portion of the second housing (220) may be transitioned to a slide-out state in which it is moved outwardly from the first housing (210) at least partially along the first direction (direction ①) by driving the drive motor (260). In one embodiment, the flexible display (230) may be supported by the support bracket (225) and moved together with the support member (240) in the slide-out state (state of FIG. 5c) of the electronic device (200), such that the portion that has slid in to the first space (2101) may be exposed so that it is at least partially visible to the outside. In this case, the flexible display (230) may have a second display area that is expanded beyond the first display area (e.g., a display area including the first portion (230a) and the second portion (230b) of FIG. 3a) to be exposed to the outside.

[0090] According to one embodiment, the electronic device (200) may include a battery (B) arranged through a battery mounting portion (2251) of a support bracket (225) fixed to a first space (2101) of a first housing (210). In one embodiment, since the battery (B) is arranged in the first housing (210), a separate driving gap may not be required to avoid interference with surrounding structures due to movement. Accordingly, the battery (B) may be expanded in thickness from the battery mounting portion (2251) of the support bracket (225) in a manner that it comes into close proximity to or comes into contact with the back surface of the support member (240), thereby relatively increasing the battery volume and supporting the moving support member (240), thereby reducing the sagging phenomenon of the flexible display (230) and helping to improve operational reliability.

[0091] FIG. 6 is a perspective view showing an exploded view of a protective film (300) and a flexible display (230) according to one embodiment of the present disclosure.

[0092] According to one embodiment, the flexible display (230) may include an unbreakable (UB) type OLED display (e.g., a curved display). However, the present invention is not limited thereto, and the display (230) may also include a flat type display of an on cell touch AMOLED (active matrix organic light-emitting diode) (OCTA) method.

[0093] According to one embodiment, as illustrated in FIG. 6, the flexible display (230) may include a protective layer (231), a window layer (232) sequentially disposed under the protective layer (231), a polarizing layer (233) (e.g., a polarizing film), a display panel (234), and a polymer layer (235). In some embodiments, the flexible display (230) may include a digitizer panel (not illustrated) disposed under the polymer layer (235).

[0094] According to one embodiment, the protective layer (231) can be attached to the upper part of the window layer (232) to protect the window layer (232). In one embodiment, the protective layer (231) can be formed of a hard material having a certain level of rigidity or higher so as to ensure durability against external force. For example, the protective layer (231) can be formed of a polymer material such as polyethylene terephthalate (PET), thermalplastic polyurethane (TPU), polyurethane (PU), and polyimide (PI). In addition, the protective layer (231) may also include a coating layer coated with a low-friction material (e.g., a hard coating layer or a Teflon coating layer).

[0095] In one embodiment, the protective film (300) may be attached to the outermost layer of the flexible display (230) to protect the protective layer (231). For example, the protective film (300) may be attached to the protective layer (231). In one embodiment, the protective film (300) may be a configuration that is exposed to the exterior of the electronic device (200). The protective film (300) may be subject to various damages as it is exposed to the external environment of the electronic device (200). The protective film (300) may be attached to the protective layer (231) of the flexible display (230) through an adhesive member (e.g., the first adhesive member (P1) of FIG. 8A) having adhesive strength that can be peeled off from the flexible display (230) so that it can be replaced depending on the degree of damage. In some embodiments, the protective film (300) may be directly attached to the window layer (232) to protect the window layer (232) from the external environment when the protective layer (231) is not disposed on the flexible display (230).

[0096] In one embodiment, the window layer (232) may include a glass layer. In one embodiment, the window layer (232) may include ultra-thin glass (UTG). In some embodiments, the window layer (232) may include a polymer. In this case, the window layer (232) may include polyethylene terephthalate (PET) or polyimide (PI). In some embodiments, the window layer (232) may be arranged in multiple layers to include a glass layer and a polymer. In one embodiment, the display panel (234) may include a plurality of pixels and a wiring structure. In one embodiment, the polarizing layer (233) may selectively transmit light generated from a light source of the display panel (234) and vibrating in a certain direction. In one embodiment, the polymer layer (235) may be arranged under the display panel (234) to provide a dark background for ensuring the visibility of the display panel (234) and may be formed as a buffering material for a buffering action.

[0097] Meanwhile, as described above, a protective layer (231) may be disposed on the outermost layer of the flexible display (230). The polymer material constituting the protective layer (231) or the material such as the hard coating layer or the Teflon coating layer constituting the protective layer (231) may be a low-friction material having low surface roughness. When the protective film (300) is attached to the protective layer (231), compared to the case where the protective film (300) is attached to a material having high surface roughness, such as a metal (e.g., an alloy of aluminum, stainless steel (STS, SUS), iron, magnesium, titanium, etc.) or a non-metal (e.g., a synthetic resin, ceramic, engineering plastic), the adhesive force for the protective layer (231) is not secured, and thus the protective layer (231) may be easily peeled off. For example, an adhesive member (e.g., a first folding member (P1)) disposed between a protective film (300) and a flexible display (230) can be easily peeled off from the protective layer (231) of the flexible display (230) while being attached to the protective film (300). In addition, in some embodiments, the protective film (300) can be directly attached to the window layer (232). The material constituting the window layer (232), such as PET, PI, and / or UTG, can also be a low-friction material with low surface roughness. Therefore, when the protective film (300) is attached to the window layer (232), compared to a case where the protective film (300) is attached to a material with high surface roughness, such as a metal or non-metal material, the adhesive force for the window layer (232) is not secured, and thus the protective film (300) can be peeled off from the window layer (232). Since the protective film (300) must be replaced from the flexible display (230) depending on the degree of damage, the adhesive strength of the adhesive member (e.g., the first adhesive member (P1)) that adheres the flexible display (230) and the protective film (300) may not be able to be increased indefinitely.

[0098] In one embodiment, the protective film (300) may be attached only to the active area where the screen is displayed in the flexible display (230). For example, the protective film (300) may be attached to the protective layer (231) in an area corresponding to the active area where the screen is displayed in the first portion (230a) (e.g., the flat portion) and the second portion (230b) (e.g., the bendable portion, the bending portion, and / or the inner area) of the flexible display (230). In this case, the end of the protective film (300) may be positioned in the second portion (230b) of the flexible display (230). For example, the end of the protective film (300) may be positioned in the internal space (e.g., the first space (2101)) of the electronic device (200) together with the second part (230b) of the flexible display (230) when the electronic device (200) is in a slide-in state, and may be positioned in the bent section of the second part (230b) of the flexible display (230) when the electronic device (200) is in a slide-out state. In this case, the end of the protective film (300) may be peeled off from the flexible display (230) by generating a repulsive force as it is at least partially bent in the bent section of the second part (230b) of the flexible display (230) when the electronic device (200) is in a slide-out state. In some embodiments, the protective film (300) may be attached to the entire area of ​​the flexible display (230). In this case, the end of the protective film (300) may be positioned at the end of the flexible display (230) (or the end of the second portion (230b)) so that when the electronic device (200) is in a slide-out state, it may be positioned in an internal space (e.g., the first space (2101)) of the electronic device (200). In this case, when the electronic device (200) is in a slide-out state, the length of a planar area located in the internal space (e.g., the first space (2101)) of the electronic device (200) may be reduced compared to when the electronic device (200) is in a slide-in state.The protective film (300) can be easily peeled off from the flexible display (230) through the repulsive force generated by at least some bending of the second part (230b) of the flexible display (230) as the length of the flat area located in the internal space of the electronic device (200) is shorter.

[0099] According to one embodiment of the present disclosure, the protective film (300) may be attached to a structure other than the flexible display (230) in one area. For example, one area (e.g., an end) of the protective film (300) may be attached to a material having a higher surface roughness than the protective layer (231) of the flexible display (230). Accordingly, compared to a case where the protective film (300) is attached only to the protective layer (231) of the flexible display (230), the phenomenon of the protective film (300) being peeled off from the protective layer (231) of the flexible display (230) may be alleviated or reduced. The structure thereof will be described in detail below.

[0100] Fig. 7a is a drawing showing a state in which a flexible display (230) with a protective film (300) attached to a support bracket (225) is coupled when the electronic device (200) is in a slide-in state. Fig. 7b is an exploded perspective view of one configuration of the electronic device (200) shown in Fig. 7a.

[0101] According to one embodiment, as illustrated in FIGS. 7A and 7B, the flexible display (230) may be disposed on the support member (240). In one embodiment, at least a portion of the flexible display (230) (e.g., the second portion (230b)) may be accommodated in a manner of being bent into the first space (2101) of the first housing (210) while being supported by the support member (240) in a slide-in state, thereby being disposed so as not to be visible from the outside. In one embodiment, an end of the second portion (230b) of the flexible display (230) (e.g., an end of the flexible display (230)) may always be positioned in the first space (2101) of the first housing (210) regardless of the slide-in or slide-out state of the electronic device (200).

[0102] In one embodiment, the support member (240) may include a plurality of multi-bars (241) supporting an area of ​​the flexible display (230) and a support bar (242) arranged at an end of the flexible display (230) and positioned in a first space (2101) of the first housing (210). In one embodiment, at least a portion of the support bar (242) may support an end of the flexible display (230) positioned in the first space (2101) of the first housing (210). In one embodiment, the support bar (242) may always be positioned in the first space (2101) of the first housing (210) regardless of a slide-in or slide-out state of the electronic device (200).

[0103] In one embodiment, the plurality of multi-bars (241) and the support bars (242) may include guide protrusions (2411) protruding from both ends. The plurality of multi-bars (241) and the support bars (242) may be movably coupled to the guide rail (226) by inserting the guide protrusions (2411) into guide slits (2261) formed in the guide rail (226).

[0104] According to one embodiment, the flexible display (230) may be supported by a support bracket (225). In one embodiment, the support bracket (225) may support a support member (240) disposed on the back surface of the flexible display (230). In one embodiment, the flexible display (230) may be supported by the support bracket (225) and may slide along the guide rails (226) according to the sliding motion of the electronic device (200) as guide rails (226) are disposed on both sides of the support bracket (225).

[0105] According to one embodiment, as illustrated in FIGS. 7A and 7B, the electronic device (200) may include at least one drive belt (270) (e.g., a life belt or a tension belt) to support the flexible display (230) and reduce lifting of the flexible display (230) by providing uniform tension during operation. In one embodiment, the drive belt (270) may help reduce driving resistance due to eccentricity of the second housing (220) that is moved by the driving motor (260). In one embodiment, one end (2701) of the drive belt (270) may be fixed to the support bar (242), and the other end (2702) may be fixed to at least a portion of the second extension member (222) of the second housing (220). In one embodiment, one end (2701) of the drive belt (270) may be secured to a mounting portion (243) formed on a second support portion (2422) of the support bar (242) and secured to the second support portion (2422) via a fixing plate (310) disposed on the second support portion (2422). In one embodiment, the drive belt (270) may be arranged in a manner such that it is wound around at least one rotating roller (271) rotatably disposed on the support bracket (225). In one embodiment, when the second housing (220) transitions from a slide-in state to a slide-out state, one end (2701) of the drive belt (270) may move in a first spatial direction (e.g., in the -y-axis direction) along the support bar (242), and the other end (2702) of the drive belt (270) may move in a second spatial direction (e.g., in the y-axis direction) along the second housing (220) by a corresponding amount of movement. For example, the drive belt (270) may move while being supported by at least one rotating roller (271) and a support portion (2252) of the support bracket (225), but the distance from one end (2701) fixed to the support bar (242) to the other end (2702) fixed to the second housing (220) may not change.Therefore, the drive belt (270) can help the flexible display (230) to always remain tight even during sliding operation.

[0106] FIG. 8A is a cross-sectional view taken along line P1-P1 of FIG. 2A according to one embodiment of the present disclosure. FIG. 8B is a cross-sectional view taken along line P2-P2 of FIG. 3A according to one embodiment of the present disclosure.

[0107] In one embodiment, the support bar (242) can slide along the guide rail (226) in the first space (2101) of the first housing (210). The support bar (242) can support an end of a second portion (230b) (e.g., a bendable portion, a bending portion, and / or an inner region) of the flexible display (230) at least partially located in the first space (2101) of the first housing (210). In one embodiment, the support bar (242) can include a first support portion (2421) that supports an end of the flexible display (230) and a second support portion (2422) that extends from the first support portion (2421) and is adjacent to the end of the flexible display (230). For example, the second support (2422) may extend in the + Y direction of FIG. 8A relative to the first support (2421) and may be adjacent to an end of the flexible display (230). In one embodiment, the second support (2422) may be a portion of the support bar (242) that does not support the flexible display (230). In one embodiment, at least a portion of the second support (2422) may be in contact with an end of the flexible display (230) when viewed in the + Z direction of FIG. 8A.

[0108] In one embodiment, the support bar (242) may be formed of a material having a higher surface roughness than the protective layer (231) of the flexible display (230). For example, the support bar (242) may be formed of a material having a higher surface roughness than the surface roughness of the protective layer (231) of the flexible display (230), such as a metal (e.g., an alloy of aluminum, stainless steel (STS, SUS), iron, magnesium, titanium, etc.) or a non-metal (e.g., a synthetic resin, ceramic, engineering plastic) material. Accordingly, as described below, the protective film (300) may have a higher adhesive strength to the second support portion (2422) of the support bar (242) than to the protective layer (231) of the flexible display (230).

[0109] According to one embodiment, the protective film (300) may be formed such that a length in the first direction (e.g., a length in the Y-axis direction of FIG. 8A) is longer than a length in the first direction of the flexible display (230) (e.g., a length in the Y-axis direction of FIG. 8A). In this case, a portion of the protective film (300) may protrude relative to one end of the flexible display (230). For example, a portion of the protective film (300) may protrude relative to an end of a second portion (230b) (e.g., an inner region) of the flexible display (230) located in the first space (2101) of the first housing (210). The protective film (300) may be attached to a device whose remaining area is attached to the flexible display (230) and located in the first space (2101) of the first housing (210). For example, a portion of the protective film (300) may be attached to the second support portion (2422) of the support bar (242).

[0110] In one embodiment, the protective film (300) may include a first attachment area (301) attached to the flexible display (230) and a second attachment area (302) extending from the first attachment area (301). In one embodiment, the second attachment area (302) may be an area that is not adhered to the flexible display (230). In one embodiment, the first attachment area (301) of the protective film (300) may face the first support portion (2421) of the support bar (242), and at least a portion of the second attachment area (302) of the protective film (300) may face the second support portion (2422) of the support bar (242).

[0111] According to one embodiment, as illustrated in FIGS. 8A and 8B, the protective film (300) may have a first attachment area (301) attached to the protective layer (231) of the flexible display (230), and a second attachment area (302) attached to the second support portion (2422) of the support bar (242). In one embodiment, the first attachment area (301) of the protective film (300) may be attached to the protective layer (231) of the flexible display (230) via a first adhesive member (P1). The second attachment area (302) of the protective film (300) may be attached to the second support portion (2422) of the support bar (242) via a second adhesive member (P2). As described above, the support bar (242) may be formed of a material having a higher surface roughness than the protective layer (231). In this case, the adhesive force between the second support portion (2422) and the second attachment area (302) through the second adhesive member (P2) may be stronger than the adhesive force between the protective layer (231) and the first attachment area (301) through the first adhesive member (P1). Accordingly, the protective film (300) may be attached to the second support portion (2422) of the support bar (242) having a surface roughness higher than that of the protective layer (231) of the flexible display (230), so that peeling from the flexible display (230) may be reduced or alleviated compared to the case where the protective film (300) is attached only to the protective layer (231) of the flexible display (230). In particular, a portion of the protective film (300) may be bent together with a portion of the second portion (230b) of the flexible display (230) when the electronic device (200) is in a slide-out state. The protective film (300) may not be peeled off from the flexible display (230) even if a repulsive force is generated in the banding section because the second attachment area (302) of the protective film (300) is fixed to the second support portion (2422) of the support bar (242).In addition, since the bonding force between the second attachment area (302) of the protective film (300) and the second support portion (2422) is stronger than the bonding force between the first attachment area (301) and the protective layer (231), when replacing the protective film (300), after separating the support bar (242) from the electronic device (200), the protective film (300) can be peeled off from the flexible display (230) by holding the support bar (242).

[0112] According to one embodiment, the thickness of the first adhesive member (P1) and the second adhesive member (P2) may be determined based on the degree of slippage of the protective film (300) with respect to the flexible display (230) according to the difference between the radius of curvature of the bending section of the flexible display (230) and the radius of curvature of the bending section of the protective film (300). According to one embodiment, a slip phenomenon may occur in which the protective film (300) slides with respect to the flexible display (230) according to the sliding motion of the electronic device (200). In one embodiment, referring to FIG. 8B, at least a portion of the second portion (230b) of the flexible display (230) may be bent. The protective film (300) may be bent together with the second portion (230b) of the flexible display (230) and introduced into the first space (2101). Since the protective film (300) is attached to the outermost layer (e.g., the protective layer (231)) of the flexible display (230), the bending section of the protective film (300) may have a larger radius of curvature than the bending section of the second part (230b) of the flexible display (230). Accordingly, when the electronic device (200) is switched from a slide-in state to a slide-out state, the amount by which a part of the protective film (300) located on the second part (230b) of the flexible display (230) moves in the -Y direction in the first space (2101) of the first housing (210) may be greater than the amount by which the second part (230b) of the flexible display (230) moves in the -Y direction in the first space (2101). Accordingly, when the electronic device (200) is switched from a slide-in state to a slide-out state, the end of the protective film (300) located in the first space (2101) of the first housing (210) can move in the Y direction with respect to the end of the flexible display (230) as shown in FIG. 8B. The first adhesive member (P1) can be partially deformed in the Y direction based on the movement of the protective film (300) while being adhered to the protective layer (231).In addition, the second adhesive member (P2) may be partially deformed in the -Y direction based on the movement of the protective film (300) while being adhered to the second support member (2422). Accordingly, a change in the relative position between one end of the protective film (300) and one end of the flexible display (230) based on the difference between the radius of curvature of the bending section of the second part (230b) of the flexible display (230) and the radius of curvature of the bending section of the protective film (300) can be accommodated through the first adhesive member (P1) and the second adhesive member (P2).

[0113] In one embodiment, the first adhesive member (P1) and the second adhesive member (P2) may be formed to have the same adhesive strength. In some embodiments, the first adhesive member (P1) and the second adhesive member (P2) may be configured to have different adhesive strengths to facilitate replacement of the protective film (300). For example, the second adhesive member (P2) may be formed of a material having a higher adhesive strength than the first adhesive member (P1). In this case, the bonding force between the second attachment area (302) of the protective film (300) and the second support portion (2422) of the support bar (242) may be higher than the bonding force between the first attachment area (301) of the protective film (300) and the protective layer (231). Therefore, when replacing the protective film (300), the support bar (242) can be separated from the electronic device (200), and then the support bar (242) can be gripped to peel the protective film (300) from the flexible display (230).

[0114] In one embodiment, referring to FIGS. 8A and 8B , the second adhesive member (P2) may be formed to a thickness thicker than the first adhesive member (P1) so that the first attachment area (301) and the second attachment area (302) of the protective film (300) can be flat in an area corresponding to the support bar (242). For example, since the support bar (242) supports the flexible display (230), the gap (e.g., the length in the Z-axis direction based on FIG. 8A) between the second support portion (2422) of the support bar (242) and the second attachment area (302) of the protective film (300) may be wider than the gap (e.g., the length in the Z-axis direction based on FIG. 8A) between the flexible display (230) and the first attachment area (301) of the protective film (300). Accordingly, as the second adhesive member (P2) is formed to a thickness thicker than the first adhesive member (P1), the protective film (300) can be substantially flat in the area corresponding to the support bar (242).

[0115] In the above description, the support bar (242) is described as including a first support portion (2421) and a second support portion (2422). However, the first support portion (2421) and the second support portion (2422) may not be limited to a configuration in which they are physically separated. For example, the first support portion (2421) and the second support portion (2422) are only separated to explain the relationship with the flexible display (230) and may not be a physically separated configuration. Similarly, the protective film (300) is described as including a first attachment area (301) and a second attachment area (302), but this is separated for the convenience of explanation and the first attachment area (301) and the second attachment area (302) may not be a configuration in which they are physically separated.

[0116] In one embodiment, the first adhesive member (P1) and the second adhesive member (P2) may be formed of a soft material such as an acrylic series, a silicone series, a rubber series, and a urethane series so as to be able to bend together with the flexible display (230) according to the slide-in or slide-out operation of the electronic device (200) so as to enable bending.

[0117] FIG. 9A is a drawing showing a state in which a second attachment area (302) of a protective film (300) is attached to a fixing plate (310) disposed on a second support portion (2422) of a support bar (242) according to one embodiment of the present disclosure. FIGS. 9B and 9C are drawings showing a state in which a fixing plate (310) for fixing a drive belt (270) is disposed between the second support portion (2422) of the support bar (242) and the second attachment area (302) of the protective film (300) illustrated in FIGS. 8A and 8B. FIGS. 10A to 10F are drawings explaining various embodiments of a coupling relationship between a fixing plate (310) and a second support portion (2422) of a support bar (242) according to one embodiment of the present disclosure.

[0118] Hereinafter, an embodiment is described in which a fixing plate (310) is arranged between the support bar (242) and the protective film (300) described in FIGS. 8A and 8B to fix the drive belt (270) to the support bar (242). For example, the fixing plate (310) may be arranged between the second support portion (2422) of the support bar (242) and the second attachment area (302) of the protective film (300). Hereinafter, descriptions of configurations identical or similar to those described above will be omitted.

[0119] According to one embodiment, as illustrated in FIG. 9A, a fixing plate (310) may be disposed between the second support portion (2422) of the support bar (242) and the second attachment area (302) of the protective film (300). In one embodiment, the fixing plate (310) may be disposed on the second support portion (2422) to cover one end of the drive belt (270) disposed on the mounting portion (243) of the second support portion (2422) and may be disposed on the second support portion (2422) to fix one end of the drive belt (270) to the second support portion (2422). For example, the fixing plate (310) may be coupled to the support bar (242) via a fixing member (e.g., a screw, a thread, a rivet connection, and / or a bolt and nut connection) to fix one end of the drive belt (270) to the second support portion (2422) of the support bar (242).

[0120] In one embodiment, the fixing plate (310) may be formed to have a size corresponding to the second attachment area (302) of the protective film (300). For example, referring to FIG. 9A, the width of the fixing plate (310) (e.g., the length in the X-axis direction of FIG. 9A) may correspond to the width of the second attachment area (302) (e.g., the length in the X-axis direction of FIG. 9A). In some embodiments, the fixing plate (310) may be formed to have a size corresponding to the second support portion (2422) and may be formed to be smaller than the width of the second attachment area (302). For example, the fixing plate (310) may be formed to have a size included in the second attachment area (302). In this case, as the space occupied by the fixing plate (310) and the second support portion (2422) in the first space (2101) of the first housing (210) is reduced, the space in which electronic components can be arranged may be expanded by the corresponding space.

[0121] In one embodiment, the fixing plate (310) may be formed of a material having a higher surface roughness than the protective layer (231) of the flexible display (230). For example, the fixing plate (310) may be formed of a material having a higher surface roughness than the surface roughness of the protective layer (231) of the flexible display (230), such as a metal (e.g., an alloy of aluminum, stainless steel (STS, SUS), iron, magnesium, titanium, etc.) or a non-metal (e.g., a synthetic resin, ceramic, engineering plastic) material. Accordingly, as described below, the protective film (300) may have a higher adhesive strength to the fixing plate (310) than to the protective layer (231) of the flexible display (230).

[0122] According to one embodiment, as illustrated in FIGS. 9B and 9C, the protective film (300) may have a first attachment area (301) attached to the protective layer (231) of the flexible display (230), and a second attachment area (302) attached to the fixing plate (310). In one embodiment, the first attachment area (301) of the protective film (300) may be attached to the protective layer (231) of the flexible display (230) via a first adhesive member (P1). The second attachment area (302) of the protective film (300) may be attached to the fixing plate (310) via a second adhesive member (P2). As described above, the fixing plate (310) may be formed of a material having a higher surface roughness than the protective layer (231). In this case, the adhesive force between the fixing plate (310) and the second attachment area (302) through the second adhesive member (P2) may be stronger than the adhesive force between the protective layer (231) and the first attachment area (301) through the first adhesive member (P1). Therefore, since the protective film (300) is attached to the fixing plate (310) whose second attachment area (302) has a higher surface roughness than the protective layer (231) of the flexible display (230), peeling from the flexible display (230) may be reduced or alleviated compared to the case where the protective film (300) is attached only to the protective layer (231) of the flexible display (230). In particular, a portion of the protective film (300) may be bent together with a portion of the second portion (230b) of the flexible display (230) when the electronic device (200) is in a slide-out state. The protective film (300) may not be peeled off from the flexible display (230) because the second attachment area (302) of the protective film (300) is fixed to the fixing plate (310) even if a repulsive force is generated in the banding section.In addition, since the bonding force between the second attachment area (302) of the protective film (300) and the fixed plate (310) is stronger than the bonding force between the first attachment area (301) and the protective layer (231), when replacing the protective film (300), after separating the fixed plate (310) from the electronic device (200), the protective film (300) can be peeled off from the flexible display (230) by holding the fixed plate (310).

[0123] According to one embodiment, the thickness of the first adhesive member (P1) and the second adhesive member (P2) may be determined based on the degree of slippage of the protective film (300) relative to the flexible display (230) based on the difference between the radius of curvature of the bending section of the flexible display (230) and the radius of curvature of the bending section of the protective film (300). As described in FIGS. 8A and 8B , since the protective film (300) is attached to the outermost layer (e.g., the protective layer (231)) of the flexible display (230), the bending section of the protective film (300) may have a larger radius of curvature than the bending section of the second portion (230b) of the flexible display (230). Accordingly, when the electronic device (200) is switched from a slide-in state to a slide-out state, the amount by which a part of the protective film (300) located in the second part (230b) of the display moves in the -Y direction in the first space (2101) of the first housing (210) may be greater than the amount by which the second part (230b) of the flexible display (230) moves in the -Y direction in the first space (2101) of the first housing (210). Accordingly, when the electronic device (200) is switched from a slide-in state to a slide-out state, the end of the protective film (300) located in the first space (2101) of the first housing (210) may move in the -Y direction with respect to the end of the flexible display (230) as shown in FIG. 9C. The first adhesive member (P1) may be partially deformed in the -Y direction based on the movement of the protective film (300) while being adhered to the protective layer (231). Additionally, the second adhesive member (P2) may have some shape deformation in the Y direction based on movement of the protective film (300) while being adhered to the fixed plate (310).Accordingly, a change in the relative position between one end of the protective film (300) and one end of the flexible display (230) based on the difference between the radius of curvature of the bending section of the second part (230b) of the flexible display (230) and the radius of curvature of the bending section of the protective film (300) can be accommodated through the first adhesive member (P1) and the second adhesive member (P2).

[0124] In one embodiment, the first adhesive member (P1) and the second adhesive member (P2) may be formed to have the same adhesive strength. In some embodiments, the first adhesive member (P1) and the second adhesive member (P2) may be configured to have different adhesive strengths to facilitate replacement of the protective film (300). For example, the second adhesive member (P2) may be formed of a material having a higher adhesive strength than the first adhesive member (P1). In this case, the bonding force between the second attachment area (302) of the protective film (300) and the fixed plate (310) may be higher than the bonding force between the first attachment area (301) of the protective film (300) and the protective layer (231). Therefore, when replacing the protective film (300), the fixed plate (310) may be separated from the electronic device (200), and then the fixed plate (310) may be gripped to peel the protective film (300) from the flexible display (230).

[0125] In one embodiment, referring to FIGS. 9B and 9C, the protective film (300) may be substantially flat in an area corresponding to the support bar (242). In one embodiment, the thickness of the first adhesive member (P1) may be determined according to the gap between the protective layer (231) and the first attachment area (301). In addition, the thickness of the second adhesive member (P2) may be determined according to the gap between the fixed plate (310) and the second attachment area (302). For example, when the gap between the protective layer (231) and the first attachment area (301) and the gap between the fixed plate (310) and the second attachment area (302) are the same, the thicknesses of the first adhesive member (P1) and the second adhesive member (P2) may be the same. In contrast, when the gap between the protective layer (231) and the first attachment area (301) and the gap between the fixed plate (310) and the second attachment area (302) are different from each other, the thicknesses of the first adhesive member (P1) and the second adhesive member (P2) may be the same. Accordingly, since the gap (e.g., the gap in the Z-axis direction based on FIG. 9C) between the first support portion (2421) of the support bar (242) and the protective film (300) and the gap between the second support portion (2422) and the protective film (300) become substantially the same through the first adhesive member (P1) and the second adhesive member (P2), the protective film (300) may become substantially flat in the area corresponding to the support bar (242).

[0126] According to one embodiment, as illustrated in FIGS. 10A to 10D, the second support portion (2422) of the support bar (242) may be formed in various sizes. In one embodiment, referring to FIGS. 10A and 10B, the second support portion (2422) may be formed to have a width smaller than the width of the first support portion (2421) (e.g., the length in the X-axis direction based on FIG. 10A). In addition, the second support portion (2422) may be formed to have a width smaller than the width of the fixed plate (310) (e.g., the length in the X-axis direction based on FIG. 10A). In this case, as the space occupied by the second support portion (2422) of the support bar (242) in the first space (2101) of the first housing (210) is reduced, a space for arranging electronic components may be secured by the corresponding space.

[0127] In one embodiment, referring to FIGS. 10C and 10D , the second support portion (2422) of the support bar (242) may be formed to have a size corresponding to that of the fixed plate (310). For example, the second support portion (2422) may be formed to a size such that the entire area of ​​the fixed plate (310) can be secured to the second support portion (2422). Accordingly, compared to FIG. 10A , the fixed plate (310) can be stably coupled to the second support portion (2422).

[0128] In one embodiment, referring to FIGS. 10A to 10D , the fixed plate (310) may include a first fixing hole (3111) and a second fixing hole (3121) through which a fixing member passes. The fixing member may be a screw, a screw, a rivet joint, and / or a bolt and nut, and the following description will be made on the assumption that it is a screw. The fixed plate (310) may be arranged on the second support portion (2422) such that the first fixing hole (3111) and the second fixing hole (3121) correspond to the first fixing hole (2423) and the second fixing hole (2424) formed on the second support portion (2422), respectively. In addition, the fixed plate (310) may cover the fixing belt mounting portion (243) formed on the second support portion (2422). The screws are sequentially inserted into the first fixing hole (3111) of the fixing plate (310) - the first fixing hole (2423) of the second support member (2422), and are sequentially inserted into the second fixing hole (3121) of the fixing plate (310) - the second fixing hole (2424) of the second support member (2422), thereby fixing the fixing plate (310) to the second support member (2422).

[0129] According to one embodiment, as illustrated in FIGS. 10e and 10f, the fixing plate (310) may include a first section (311) covering one side of the second support portion (2422) and having a first fixing hole (3111) formed therein, and a second section (321) covering the other side of the second support portion (2422) and having a second fixing hole (3121) formed therein. In one embodiment, the screw may sequentially pass through the first fixing hole (3111) formed in the first section (311) and the first fixing hole (2421) formed in one side of the second support portion (2422). In addition, the screw may sequentially pass through the second fixing hole (3121) formed in the second section (321) and the second fixing hole (2424) formed in one side of the second support portion (2422). Accordingly, the fixed plate (310) can be fixed to the second support (2422) via a screw.

[0130] According to one embodiment, when the screw is inserted into the cut-off portion (311, 312) located on the side of the fixed plate (310) as shown in FIGS. 10e and 10f, the attachment area of ​​the second attachment area (302) to the fixed plate (310) can be increased compared to when the screw is inserted into one side of the fixed plate (310) where the second attachment area (302) of the protective film (300) is arranged as shown in FIGS. 10b and 10d.

[0131] FIG. 11a and FIG. 11b are drawings showing a state in which a lattice plate (320) including a mesh structure (321) is placed between the fixed plate (310) and the second attachment area (302) of the protective film (300) illustrated in FIGS. 9a to 9c.

[0132] Hereinafter, an embodiment in which a lattice plate (320) having a mesh structure (e.g., a mesh structure) is formed between a second support portion (2422) of a support bar (242) described in FIGS. 8a and 8b and a protective film (300) is disposed, and an embodiment in which a lattice plate is disposed between a fixed plate (310) and a protective film (300) described in FIGS. 9a and 9b are described. In the following, descriptions of configurations identical or similar to those described above will be omitted.

[0133] According to one embodiment, a lattice plate (320) may be disposed between the second support portion (2422) of the support bar (242) and the second attachment area (302) of the protective film (300), as illustrated in FIGS. 11A and 11B. In one embodiment, the lattice plate (320) may include a mesh structure (321) including a grid pattern and / or a mesh pattern. In one embodiment, the lattice plate (320) may be positioned between the fixed plate (310) and the second attachment area (302) of the protective film (300). In one embodiment, the lattice plate (320) may be adhered to the fixed plate (310) via a third adhesive member (P3). Hereinafter, the description will be made on the assumption that the lattice plate (320) is disposed on the fixed plate (310).

[0134] In one embodiment not shown in the drawing, the lattice plate (320) may be disposed on the second support portion (2422) of the support bar (242) and positioned between the second support portion (2422) and the second attachment area (302) of the protective film (300). For example, as shown in FIGS. 8A and 8B , when the fixing plate (310) is not disposed on the second support portion (2422), the lattice plate (320) may be fixed to the second support portion (2422) of the support bar (242) in various ways, such as an adhesive member, a screw connection, a bolt-nut connection, or a rivet connection.

[0135] In one embodiment, the first attachment area (301) of the protective film (300) may be attached to the protective layer (231) via a first adhesive member (P1), and the second attachment area (302) may be attached to the lattice plate (320) via a second adhesive member (P2). In one embodiment, the lattice plate (320) may be formed to have a size corresponding to the second attachment area (302) of the protective film (300). For example, the width of the lattice plate (320) may correspond to the width of the second attachment area (302). In one embodiment, the lattice plate (320) may be formed to have a size corresponding to the fixed plate (310).

[0136] In one embodiment, the lattice plate (320) may be formed of a material having a higher surface roughness than the protective layer (231) of the flexible display (230). For example, the lattice plate (320) may be formed of a material having a higher surface roughness than the surface roughness of the protective layer (231) of the flexible display (230), such as a metal (e.g., an alloy of aluminum, stainless steel (STS, SUS), iron, magnesium, titanium, etc.) or a non-metal (e.g., a synthetic resin, ceramic, engineering plastic) material. Accordingly, the protective film (300) may have a higher adhesive strength to the lattice plate (320) than to the protective layer (231) of the flexible display (230).

[0137] In one embodiment, referring to FIGS. 11A and 11B, the protective film (300) may have a first attachment area (301) attached to the protective layer (231) via a first adhesive member (P1), and a second attachment area (302) attached to the lattice plate (320) via a second adhesive member (P2). As described above, the lattice plate (320) may be formed of a material having a higher surface roughness than the protective layer (231). In this case, the adhesive force between the second lattice plate (230) and the second attachment area (302) via the second adhesive member (P2) may be stronger than the adhesive force between the protective layer (231) and the first attachment area (301) via the first adhesive member (P1). Accordingly, since the second attachment area (302) of the protective film (300) is attached to the lattice plate (320) having a higher surface roughness than the protective layer (231), peeling from the flexible display (230) can be reduced or alleviated compared to the case where the protective film (300) is attached only to the protective layer (231). In particular, a portion of the protective film (300) can be bent together with a portion of the second portion (230b) of the flexible display (230) when the electronic device (200) is in a slide-out state. Even if a repulsive force is generated in the bending section, the protective film (300) may not be peeled from the flexible display (230) since the second attachment area (302) of the protective film (300) is fixed to the lattice plate (320).

[0138] In one embodiment, the mesh structure (321) formed on the lattice plate (320) can increase the bonding strength between the lattice plate (320) and the protective film (300) through the second adhesive member (P2). In one embodiment, at least a portion of the second adhesive member (P2) and at least a portion of the third adhesive member (P3) can be adsorbed to the mesh structure (321) of the lattice plate (320). In this case, the adhesive strength between the second adhesive member (P2) and the lattice plate (320) can be increased compared to a case where the second adhesive member (P2) is bonded to one plane of the lattice plate (320) rather than the mesh structure (321). Similarly, the adhesive strength between the third adhesive member (P3) and the lattice plate (320) can be increased compared to a case where the third adhesive member (P3) is bonded to one plane of the lattice plate (320) rather than the mesh structure (321).

[0139] Accordingly, the bonding strength between the lattice plate (320) and the protective film (300) through the second adhesive member can be increased. In addition, the bonding strength between the lattice plate (320) and the fixed plate (310) through the third adhesive member (P3) can be increased.

[0140] In one embodiment, as described above with reference to FIGS. 9b and 9c, since the protective film (300) is attached to the outermost layer (e.g., the protective layer (231)) of the flexible display (230), the bending section of the protective film (300) may have a larger radius of curvature than the bending section of the second part (230b) of the flexible display (230). Accordingly, when the electronic device (200) is switched from a slide-in state to a slide-out state, the amount by which a portion of the protective film (300) located at the second part (230b) of the display moves in the -Y direction in the first space (2101) of the first housing (210) may be greater than the amount by which the second part (230b) of the flexible display (230) moves in the -Y direction in the first space (2101). Accordingly, when the electronic device (200) is switched from a slide-in state to a slide-out state, the end of the protective film (300) located in the first space (2101) of the first housing (210) can move in the Y direction with respect to the end of the flexible display (230) as shown in FIG. 11B. The first adhesive member (P1) can be partially deformed in the Y direction based on the movement of the protective film (300) while being adhered to the protective layer (231). In addition, the second adhesive member (P2) can be partially deformed in the Y direction based on the movement of the protective film (300) while being adhered to the lattice plate (320). Meanwhile, the mesh structure (321) of the lattice plate (320) can be freely deformed. For example, when the electronic device (200) is switched from a slide-in state to a slide-out state, the shape of the mesh structure (321) can be deformed in the Y direction together with the second adhesive member (P2) based on the movement of the protective film (300).Accordingly, a change in the relative position between one end of the protective film (300) and one end of the flexible display (230) based on the difference between the radius of curvature of the bending section of the second part (230b) of the flexible display (230) and the radius of curvature of the bending section of the protective film (300) can be accommodated through deformation of the first adhesive member (P1), deformation of the second adhesive member (P2), and deformation of the mesh structure (321) of the lattice plate (320).

[0141] FIGS. 12A and 12B are drawings showing a state in which a fixed plate (310) is slidably coupled to a second support portion (2422) of a support bar (242) according to one embodiment of the present disclosure. FIG. 12C is a drawing explaining a coupling relationship between the fixed plate (310) and the second support portion (2422) of FIG. 12A. FIGS. 12D and 12E are drawings showing a state in which a bearing ball (331) is arranged between the second support portion (2422) of the support bar (242) and the fixed plate (310) according to one embodiment of the present disclosure.

[0142] According to one embodiment, the fixed plate (310) can be movably coupled to the second support portion (2422) of the support bar (242). For example, the fixed plate (310) can slide relative to the second support portion (2422) of the support bar (242) in the first space (2101) of the first housing (210) based on the sliding motion of the electronic device (200) while the protective film (300) is attached.

[0143] In one embodiment, the flexible display (230) may have a second portion (230b) located in the first space (2101) of the first housing (210) move in the -Y direction with respect to FIG. 12A so that the second portion (230b) of the flexible display (230) has a second display area larger than the first display area when the electronic device (200) is switched from a slide-in state to a slide-out state. Meanwhile, as described above, since the protective film (300) is attached to the outermost layer (e.g., the protective layer (231)) of the flexible display (230), the bending section of the protective film (300) may have a larger radius of curvature than the bending section of the second portion (230b) of the flexible display (230). Accordingly, when the electronic device (200) is switched from a slide-in state to a slide-out state, the amount by which a part of the protective film (300) located in the second part (230b) of the display moves in the -Y direction in the first space (2101) of the first housing (210) may be greater than the amount by which the second part (230b) of the flexible display (230) moves in the -Y direction in the first space (2101) of the first housing (210). Accordingly, when the electronic device (200) is switched from a slide-in state to a slide-out state, the end of the protective film (300) located in the first space (2101) of the first housing (210) may move in the -Y direction with respect to the end of the flexible display (230) as shown in FIG. 12B. The first adhesive member (P1) may be partially deformed in the -Y direction based on the movement of the protective film (300) while being adhered to the protective layer (231). In addition, the second adhesive member (P2) may be partially deformed in the Y direction based on the movement of the protective film (300) while being adhered to the fixed plate (310). Meanwhile, the fixed plate (310) may slide in the Y direction relative to the second support member (2422) by the amount that the protective film (300) moves relative to the end of the flexible display (230) when the electronic device (200) is switched from a slide-in state to a slide-out state.Accordingly, a change in the relative position between one end of the protective film (300) and one end of the flexible display (230) based on the difference between the radius of curvature of the bending section of the second part (230b) of the flexible display (230) and the radius of curvature of the bending section of the protective film (300) can be accommodated through deformation of the first adhesive member (P1), deformation of the second adhesive member (P2), and sliding of the fixing plate (310) with respect to the second support member (2422).

[0144] According to one embodiment, the fixed plate (310) can be coupled to the second support (2422) so as to be slidable in various ways with respect to the second support (2422). In one embodiment, referring to FIGS. 12c, 12d, and 12e, a bearing ball (331) can be arranged between the fixed plate (310) and the second support (2422) to guide the sliding of the fixed plate (310) with respect to the second support (2422). In one embodiment, a ball guide portion (330) on which the bearing ball (331) is seated can be formed on at least one of the second support (2422) and the fixed plate (310). In one embodiment, referring to FIG. 12d, the second support (2422) can be formed with a ball guide portion (330) on which the bearing ball (331) is seated. The ball guide portion (330) may be formed in the sliding direction of the fixed plate (310) with respect to the second support portion (2422) (e.g., the Y-axis direction with reference to FIG. 12B). In one embodiment, referring to FIG. 12E, the ball guide portion (330) may be formed on one surface of the fixed plate (310) facing the bearing ball (331). Accordingly, the fixed plate (310) may move with respect to the second support portion (2422) via the bearing ball (331) based on the relative movement of the protective film (300) with respect to the flexible display (230) according to the sliding operation of the electronic device (200).

[0145] FIG. 13 is a drawing showing a state in which an area of ​​a protective film (300) that is easily peeled off from a flexible display (230) is removed according to one embodiment of the present disclosure.

[0146] According to one embodiment, the fixed plate (310) may be formed in a shape corresponding to the second support portion (2422) of the support bar (242) illustrated in FIG. 10A. For example, the width of the fixed plate (310) (e.g., the length in the X-axis direction based on FIG. 10A) may be smaller than the width of the first support portion (2421) of the support bar (242). In this case, as the space occupied by the second support portion (2422) of the support bar (242) and the fixed plate (310) in the first space (2101) of the 1st housing is reduced, a space for arranging electronic components can be secured by the corresponding space.

[0147] In one embodiment, referring to FIG. 13, the second attachment area (302) of the protective film (300) may be formed to correspond to the size of the fixed plate (310). In this case, the width (e.g., the length in the X-axis direction based on FIG. 13) of the second attachment area (302) of the protective film (300) illustrated in FIG. 13 may be smaller than the width (e.g., the length in the X-axis direction based on FIG. 9A) of the second attachment area (302) of the protective film (300) illustrated in FIG. 9A. Compared to the protective film (300) illustrated in FIG. 9A, the area where the second attachment area (302) adheres to the fixed plate (310) may be reduced in the protective film (300) illustrated in FIG. 13. Accordingly, a region of the protective film (300) (e.g., an end of the protective film (300) positioned at the end of the flexible display (230)) may be peeled off from the flexible display (230) due to the repulsive force generated in the bending section of the protective film (300) that is bent together with the second part (230b) of the flexible display (230). To alleviate this phenomenon, as illustrated in FIG. 13, the protective film (300) may have a first region (303) and a second region (304) that may be peeled off from the flexible display (230) removed. In one embodiment, the first region (303) and the second region (304) may be regions where stress due to the repulsive force generated in the bending section of the protective film (300) is concentrated. Accordingly, the phenomenon of the protective film (300) being peeled off from the flexible display (230) due to a decrease in the width of the second attachment area (302) of the protective film (300) can be alleviated.
