Description

Technical Field

[0001] Various embodiments of this disclosure relate to a flexible display and an electronic device including the flexible display. Background Technology

[0002] Electronic devices require small form factors for portability and large displays to provide users with large amounts of information. To achieve both small size and large display area in electronic devices, various shape factors such as foldable, sliding, or rollable designs are emerging, moving away from rectangular or bar-shaped designs. Electronic devices with these shape factors require flexible displays that can change shape through folding or bending.

[0003] The flexible display can be disposed in the space formed by the housing. When the flexible display is installed, there may be a gap (or space) between the side surface of the flexible display and the housing at a predetermined distance, and this can be referred to as a "gap".

[0004] During the bending operation of a flexible display, if a panel-side protective member (e.g., a decorative member) with a separate structure designed to cover the gap is not used, the gap may not be completely sealed, and external foreign objects such as sand and dust may intrude into the panel side, causing damage to the panel. Furthermore, in cases where the panel-side protective member includes joints with complex mobility, the panel-side protective member is assembled to the side surface of the flexible display via a separate assembly process, which may increase the complexity of the electronic device's manufacturing process.

[0005] Therefore, by filling the gap between the side surface of the flexible display and the housing with protective components (e.g., sealing components or protective components), foreign objects can be prevented from entering the flexible display. Summary of the Invention

[0045] The power management module 188 manages the power supply to the electronic device 101. According to an embodiment, the power management module 188 may be implemented as at least part of, for example, a power management integrated circuit (PMIC).

[0046] Battery 189 can power at least one component of electronic device 101. According to embodiments, battery 189 may include, for example, a non-rechargeable primary battery, a rechargeable accumulator, or a fuel cell.

[0047] Communication module 190 can support the establishment of a direct (e.g., wired) or wireless communication channel between electronic device 101 and external electronic devices (e.g., electronic device 102, electronic device 104, or server 108), and perform communication via the established communication channel. Communication module 190 may include one or more communication processors capable of operating independently of processor 120 (e.g., application processor (AP)) and support direct (e.g., wired) or wireless communication. According to embodiments, communication module 190 may include wireless communication module 192 (e.g., cellular communication module, short-range wireless communication module, or Global Navigation Satellite System (GNSS) communication module) or wired communication module 194 (e.g., local area network (LAN) communication module or power line communication (PLC) module). One of these communication modules can communicate with an external electronic device via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wi-Fi Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a traditional cellular network, 5G network, next-generation communication network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip) or as multiple components separate from each other (e.g., multiple chips). The wireless communication module 192 can use user information (e.g., an International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196 to identify and verify the electronic device 101 in the communication network (such as the first network 198 or the second network 199).

[0048] Wireless communication module 192 can support 5G networks following 4G networks and next-generation communication technologies (e.g., 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).

[0049] Antenna module 197 can transmit or receive signals or power to or from the exterior of electronic device 101 (e.g., external electronic device). According to an embodiment, antenna module 197 may include an antenna comprising a radiating element formed using a conductive material or conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)). According to an embodiment, antenna module 197 may include multiple antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication scheme used in a communication network (such as a first network 198 or a second network 199) can be selected from the multiple antennas by, for example, communication module 190 (e.g., wireless communication module 192). Signals or power can be transmitted or received between communication module 190 and external electronic device via the selected at least one antenna. According to an embodiment, additional components besides the radiating element (e.g., a radio frequency integrated circuit (RFIC)) may be additionally incorporated into antenna module 197.

[0050] According to various embodiments, antenna module 197 can form a millimeter-wave antenna module. According to an embodiment, the millimeter-wave antenna module may include a printed circuit board, an 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 in the specified high-frequency band.

[0051] At least some of the aforementioned components can be interconnected via an inter-peripheral communication scheme (e.g., bus, general purpose input / output (GPIO), serial peripheral interface (SPI), or mobile industrial processor interface (MIPI)) and signals (e.g., commands or data) can be communicated between them.

[0052] According to an embodiment, commands or data can be sent or received between electronic device 101 and external electronic device 104 via server 108 connected to a second network 199. Each of electronic device 102 or electronic device 104 can be a device of the same type as electronic device 101, or a device of a different type. According to an embodiment, all or some operations that would be performed on electronic device 101 can be performed on one or more of external electronic devices 102, 104, or 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 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 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, one or more external electronic devices may perform at least a portion of the requested function or service, or perform additional functions or services related to the request, and transmit the result of the execution to electronic device 101. Electronic device 101 may provide the result as at least a partial response to the request, with or without further processing of the result. For this purpose, technologies such as cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing may be used.

[0053] The electronic device according to embodiments of this disclosure can be one of various types of electronic devices. Electronic devices may include, for example, portable communication devices (e.g., smartphones), computer devices, portable multimedia devices, portable medical devices, cameras, wearable devices, or home appliances. According to embodiments of this disclosure, the electronic device is not limited to those described above.

[0054] According to various embodiments, portable electronic devices (e.g., Figure 1The electronic device 101 may have a foldable housing divided into two housings based on a folding axis. A first portion of a display (e.g., a flexible display) may be disposed in the first housing, and a second portion of the display may be disposed in the second housing. The foldable housing may be implemented in an inward folding manner with the first and second portions facing each other when the portable electronic device is folded. Alternatively, the foldable housing may be implemented in an outward folding manner with the first and second portions facing opposite directions when the portable electronic device is folded. The surfaces on which the first and second portions of the display are disposed may be defined as the front surface of the portable electronic device, the opposing surfaces may be defined as the rear surface of the portable electronic device, and the surface surrounding the space between the front and rear surfaces may be defined as the side surface of the portable electronic device.

[0055] According to the embodiments mentioned in this document, when the display of a portable electronic device is folded, an inward folding configuration is described as an example, where the first portion of the display in the first housing faces the second portion of the display in the second housing. However, according to the embodiments, when the display is folded, an outward folding configuration where the first portion of the display in the first housing 210 faces the opposite direction to the second portion of the display in the second housing is also applicable. Furthermore, the various embodiments described in this document can be applied to foldable electronic devices that combine inward folding with inward folding, inward folding with outward folding, or outward folding with outward folding.

[0056] The electronic device described below can be understood as illustrating a portable electronic device 200 having an inwardly folding housing structure (e.g., Figure 2a (and below, electronic device 200). For ease of description, based on the front surface of the electronic device 200 in its unfolded state, the rightward direction can be defined as the x-axis direction, and the upward direction can be defined as the y-axis direction. Furthermore, based on the front surface of the electronic device 200 in its unfolded state, the height direction (or thickness direction) can be defined as the z-axis direction. However, the above directions do not limit the position of the components constituting the electronic device 200, and can be defined from various angles depending on the operating state of the electronic device 200 (e.g., unfolded state, folded state, or intermediate state).

[0057] Figure 2a This is a perspective view of an electronic device 200 in an unfolded (flat or open) state, as viewed from the front according to an embodiment.

[0058] Figure 2b This is a front view showing the electronic device 200 in an unfolded state according to an embodiment.

[0059] Figure 2c This is a rear view showing the electronic device 200 in its unfolded state according to an embodiment.

[0060] Figure 2d This is a perspective view showing an electronic device 200 in a middle (or partially folded) state as viewed from the front according to an embodiment.

[0061] Reference Figures 2a to 2d The electronic device 200 may include a first housing 210, a second housing 220, a hinge assembly 240 connecting the first housing 210 and the second housing 220 such that the second housing 220 can rotate relative to the first housing 210, a flexible or foldable display 299 disposed within the space formed by the foldable housings 210 and 220, and a sensor module (e.g., Figure 1 (Sensor module 176).

[0062] According to an embodiment, a display 299 may be disposed from a first housing 210 across a hinge assembly 240 to a second housing 220. The display 299 may be divided, based on a folding axis A, into a first display area 211 disposed within the interior space of the first housing 210 and a second display area 221 disposed within the interior space of the second housing 220. Viewed from the front, a sensor module (e.g., an illuminance sensor) may be disposed below a sensor area (or light-transmitting area) 242a of the first display area 211. The position and / or size of the sensor area 242a within the first display area 211 may be determined by the position and / or size of the illuminance sensor disposed below it. For example, the size (e.g., diameter) of the sensor area 242a may be determined based on the field of view (FOV) of the illuminance sensor. In an embodiment, the sensor area 242a may be configured to have a lower pixel density and / or lower line density than the surrounding area to enhance light transmittance.

[0063] According to an embodiment, the hinge assembly 240 can be in an unfolded state when the portable electronic device 200 is in such a state (e.g., Figure 2a The state transitions to the folded state (e.g., the state of the folded state). Figure 2c The folding mechanism allows the two display areas 211 and 221 to fold inwards, facing each other. For example, when the electronic device 200 is in the unfolded state, the two display areas (e.g., the first display area 211 and the second display area 221) can face substantially the same direction. When the state transitions from unfolded to folded, the two display areas 211 and 221 can rotate in the direction they face each other. The hinge assembly 240 can be configured such that the foldable housings 210 and 220 have resistance to rotation. When an external force exceeding the resistance is applied to the foldable housings 210 and 220, the foldable housings 210 and 220 can rotate.

[0064] According to an embodiment, the state of the electronic device 200 can be defined based on the angle formed between the two display areas 211, 221. For example, when the angle between the two display areas 211, 221 is approximately 180 degrees, the state of the electronic device 200 can be defined as an unfolded (flat or open) state. When the angle between the two display areas 211, 221 is between approximately 0 degrees and approximately 10 degrees, the state of the portable electronic device 200 can be defined as a folded (or closed) state. When the two display areas 211, 221 form an angle greater than the angle in the folded state and less than the angle in the unfolded state (e.g., between approximately 10 degrees and approximately 179 degrees), the state of the portable electronic device 200 can be defined as an intermediate state (i.e., a partially folded or partially unfolded state), such as... Figure 2e As shown in the image.

[0065] According to an embodiment, in the unfolded state, the first housing 210 may include a first surface (first display area) 211 facing a first direction (e.g., front direction) (z-axis direction) and a second surface 212 facing a second direction (e.g., rear direction) (-z-axis direction) opposite to the first surface 211. In the unfolded state, the second housing 220 may include a third surface (second display area) 221 facing the first direction (e.g., z-axis direction) and a fourth surface 222 facing the second direction (e.g., -z-axis direction). The electronic device 200 may be operated such that in the unfolded state, the first surface 211 of the first housing 210 and the third surface 221 of the second housing 220 face the same first direction (e.g., z-axis direction), and in the folded state, the first surface 211 and the third surface 221 face each other. The electronic device 200 may be operated such that in the unfolded state, the second surface 212 of the first housing 210 and the fourth surface 222 of the second housing 220 face the same second direction (-z-axis direction), and in the folded state, the second surface 212 and the fourth surface 222 face opposite directions.

[0066] According to an embodiment, the first housing 210 may include a first side frame 213 that at least partially forms the appearance of the electronic device 200 and a first back cover 214 that is coupled to the first side frame 213 and forms at least a portion of the second surface 212 of the electronic device 200. For example, the first side frame 213 may include a first side 213a, a second side 213b extending from one end of the first side 213a, and a third side 213c extending from the other end of the first side 213a. For example, the first side frame 213 may be formed into a rectangular (e.g., square or rectangular) shape by means of the first side 213a, the second side 213b, and the third side 213c. At least a portion of the first side frame 213 may be formed using a conductor.

[0067] According to an embodiment, the second housing 220 may include a second side frame 223 that at least partially forms the exterior of the electronic device 200, and a second rear cover 224 that is coupled to the second side frame 223 and forms at least a portion of the fourth surface 222 of the electronic device 200. For example, the second side frame 223 may include a fourth side 223a, a fifth side 223b extending from one end of the fourth side 223a, and a sixth side 223c extending from the other end of the fourth side 223a. For example, the second side frame 223 may be formed into a rectangular shape by means of the fourth side 223a, the fifth side 223b, and the sixth side 223c. At least a portion of the second side frame 223 may be formed using a conductor.

[0068] According to the embodiments, the pair of housings 210 and 220 are not limited to the shapes and combinations shown, but can be implemented in other shapes or through combinations and / or combinations of other components. For example, the first side frame 213 may be integrally formed with the first rear cover 214, and the second side frame 223 may be integrally formed with the second rear cover 224.

[0069] According to an embodiment, the first back cover 214 and the second back cover 224 may be formed by at least one or a combination of glass, ceramic, polymer or metal (e.g., aluminum, stainless steel (STS) or magnesium) that is coated or colored.

[0070] According to an embodiment, the electronic device 200 may include a first cover member 215 disposed along the edge of the first housing 210 (e.g., Figure 4 The first protective member 410). The electronic device 200 may include a second cover member 225 disposed along the edge of the second housing 220 (e.g., Figure 4 (First protective member 410). For example, the first cover member 215 and the second cover member 225 may be formed using polymer materials.

[0071] According to an embodiment, the electronic device 200 may include a sub-display 231 disposed separately from the display 299. For example, the sub-display 231 may be configured to be at least partially exposed on a second surface 212 of the first housing 210 and may display status information of the electronic device 200 in a folded state. For example, the sub-display 231 may be configured to be visible from the outside through at least a portion of the first rear cover 214. In some embodiments, the sub-display 231 may be disposed on a fourth surface 222 of the second housing 220. In this case, the sub-display 231 may be configured to be visible from the outside through at least a portion of the second rear cover 224.

[0072] According to an embodiment, the electronic device 200 may include at least one of an input device 203, an audio output device 201, 202, a camera module 205, 208, a key input device 206, a connector port 207, and a sensor module (not shown). In an embodiment, viewed from the front, the sensor module (e.g., Figure 1 The sensor module 176 and camera 205 can be positioned below the display 299.

[0073] According to an embodiment, the electronic device 200 can be operated to maintain an intermediate state via the hinge assembly 240. In this case, the electronic device 200 can control the display 299 such that different content is displayed in the display area corresponding to the first surface 211 and the display area corresponding to the third surface 221.

[0074] Figure 2e This is an exploded perspective view of an electronic device 200 according to an embodiment.

[0075] Reference Figure 2e The electronic device 200 may include a first side frame 213, a second side frame 223, and a hinge assembly 240 rotatably connecting the first side frame 213 and the second side frame 223. For example, the electronic device 200 may include a first support plate 2131 extending at least partially from the first side frame 213 and a second support plate 2231 extending at least partially from the second side frame 223. For example, the first support plate 2131 may be integrally formed with or structurally coupled to the first side frame 213. Similarly, the second support plate 2231 may be integrally formed with or structurally coupled to the second side frame 223. For example, the electronic device 200 may include a display 299 configured to be supported by the first support plate 2131 and the second support plate 2231. For example, electronic device 200 may include a first rear cover 214 and a second rear cover 224. The first rear cover 214 is coupled to a first side frame 213 and provides a first space between the first rear cover 214 and a first support plate 2131. The second rear cover 224 is coupled to a second side frame 223 and provides a second space between the second rear cover 224 and a second support plate 2231. In an embodiment, the first side frame 213 and the first rear cover 214 may be integrally formed. In an embodiment, the second side frame 223 and the second rear cover 224 may be integrally formed. For example, electronic device 200 may include a first housing 210 disposed via the first side frame 213, the first support plate 2131, and the first rear cover 214. For example, electronic device 200 may include a second housing 220 disposed via the second side frame 223, the second support plate 2231, and the second rear cover 224.

[0076] According to an embodiment, the hinge assembly 240 may include a first arm structure coupled to a first housing 210 (e.g., a first support plate 2131), a second arm structure coupled to a second housing 220 (e.g., a second support plate 2231), and a detent structure that physically contacts the first and second arm structures to give the first and second housings 210 and 220 resistance to rotation. Due to the contact force of the detent structure (e.g., a force pushing the first and second arm structures), the foldable housings 210, 220 may have resistance to rotation.

[0077] According to an embodiment, the electronic device 200 may include a first board assembly 261 (e.g., a main printed circuit board), a camera assembly 263, a first battery 271, or a first bracket 251 disposed in a first space between the first side frame 213 and the first rear cover 214. For example, the camera assembly 263 may include multiple cameras (e.g., Figure 2a and Figure 2c The camera modules 205 and 208 are electrically connected to the first board assembly 261. For example, the first bracket 251 can provide a support structure and enhanced rigidity for supporting the first board assembly 261 and / or the camera assembly 263. For example, the electronic device 200 may include a second board assembly 262 (e.g., a sub-printed circuit board), an antenna 290 (e.g., a coil member), a second battery 272, or a second bracket 252 disposed in a second space between the second side frame 223 and the second rear cover 224. For example, the electronic device 200 may include a wire member 280 (e.g., a flexible printed circuit board (FPCB)) extending from the first board assembly 261 across the hinge assembly 240 to a plurality of electronic components (e.g., the second board assembly 262, the second battery 272, or the antenna 290) disposed between the second side frame 223 and the second rear cover 224, and providing electrical connections.

[0078] According to an embodiment, the electronic device 200 may include a hinge cover 241 that supports a hinge assembly 240, is exposed to the outside when the electronic device 200 is in a folded state, and is configured to be invisible from the outside by retracting into a first space and a second space when the electronic device 200 is in an unfolded state.

[0079] According to an embodiment, the electronic device 200 may include a first cover member 215 joined along the edge of a first side frame 213. For example, the electronic device 200 may include a second cover member 225 joined along the edge of a second side frame 223. In the display 299, the edge of a first display area 211 may be protected by the first cover member 215. The edge of a second display area 221 may be protected by the second cover member 225.

[0080] In the following text, the first protective member (e.g., between the display 299 of the electronic device 200 and the side frame (e.g., the first side frame 213 and the second side frame 223) is mainly described. Figure 4 The first protective member 410) and the second protective member (e.g.,) disposed along the periphery of the rear surface of the display 299. Figure 3a The second protective member 420). The display 299 is supported by the first support plate 2131 and the second support plate 2231, and a predetermined distance may be provided between the side surface of the display 299 and the side frames 213, 223, which may be referred to as a gap (or assembly gap or assembly clearance). This gap may be provided to ensure space for sliding that occurs when the display 299 is repeatedly folded and unfolded. This gap may be set to about 0.5 mm or greater. Therefore, predetermined particulate foreign objects (or impurities) may penetrate the gap and be introduced into the side surface of the display 299 or the interior of the electronic device 200. Foreign objects (or impurities) may damage the display panel (e.g., Figure 3a The display panel 330 may be scratched or cause scratches on each layer constituting the display 299. Therefore, the first protective member 410 and the second protective member 420 can prevent foreign objects from being introduced (or penetrated) into the side surface and / or rear surface of the display 299.

[0081] Figure 3a This is an exploded perspective view showing a flexible display 300 according to an embodiment. For ease of description, the z-axis direction (the direction in which image information of the flexible display 300 is displayed) in the figures may be referred to as the upward direction, upper part, or upper surface, and the direction perpendicular to the z-axis may be referred to as the lateral direction, lateral part, or side surface.

[0082] Reference Figure 3a The flexible display 300 (e.g., display 299 of FIG. 2) may include a protective layer 310, a cover window 320, a display panel 330, and a back cover 340. The protective layer 310 may be a layer that protects the flexible display 300 from contamination, scratches, and external physical damage. For example, the protective layer 310 may include a synthetic resin film such as PET or polyurethane.

[0083] According to an embodiment, the cover window 320 may be a layer that provides rigidity to the front surface of the display panel 330 and protects the display panel 330 from external forces such as impacts or compression. For example, the cover window 320 may comprise a transparent polymer material (such as colorless polyimide) and / or an ultrathin glass material. The ultrathin glass may have a predetermined thickness to maintain flexibility. The ultrathin glass may have a thickness of, for example, 100 micrometers or less.

[0084] According to an embodiment, the display panel 330 may be an area for displaying image information. The display panel 330 may include an AMOLED or similar electroluminescent display. In some embodiments, the display panel 330 may include a polarizing film, a panel region 332, and a plastic film 333. The panel region 332 may include, for example, a plurality of light-emitting elements (such as AMOLED), electrodes supplying power to the light-emitting elements, and control circuitry. The polarizing film is located on the upper part of the panel region 332 and can reduce visibility degradation due to reflected light by polarizing light emitted from the panel region 332 and reflected light reflected from the rear surface of the panel region 332. The plastic film 333 may include a substrate for forming the panel region 332. The plastic film 333 may include a substrate capable of providing flexibility to the display panel 330 using a synthetic resin material. For example, the display panel 330 may include a touch screen panel (not shown).

[0085] According to embodiments, the support housing 350 helps enhance the rigidity of the electronic device, shields against environmental noise generated from other components of the electronic device, and can be used to dissipate heat generated during operation of the display panel 330. The support housing 350 provides a predetermined space for housing the flexible display 300. The support housing 350 may include a metallic material. Metals are effective for noise shielding and heat dissipation due to their electrical and thermal conductivity. The metal may include stainless steel, aluminum, copper, or composites thereof (e.g., components in which different metals are laminated in a plate-like manner). In some embodiments, the support housing 350 may include a grid structure capable of bending during bending operations of the flexible display 300 and mechanically supporting the components of the flexible display 300.

[0086] According to an embodiment, a portion of the support housing 350 may be structurally integrated with side frames (e.g., first side frame 213 and second side frame 223). For example, the inner sides of the side frames 213, 223 and the side surfaces of the support housing 350 may be physically joined together in a state where they are in contact with each other. For example, the side frames 213, 223 and the support housing 350 may be integrally formed. The flexible display 300 may be disposed on the front side of the structure integrally formed by the side frames 213, 223 and the support housing 350.

[0087] According to an embodiment, the support housing 350 may include a plurality of holes (e.g., Figure 3b The first hole 370 and the second hole 380). A plurality of holes 370, 380 may include a first hole 370 and a second hole 380. The first hole 370 may form a first protective member (e.g., Figure 4 The first protective member 410 has an injection inlet. The first hole 370 may be referred to as an "injection hole." The second hole 380 forms an inlet through which a light source passes to partially cure the first protective member 410. The second hole 380 may be referred to as a "light source illumination hole." (See reference...) Figure 3bDescribe multiple holes 370 and 380.

[0088] According to an embodiment, a second protective member 420 may be disposed between the support housing 350 and the display panel 330. The second protective member 420 may be disposed along at least a portion of the rearward edge of the display panel 330. The second protective member 420 may close the area formed between the support housing 350 and the display panel 330 (e.g., a gap of predetermined thickness). Therefore, in the case of a first protective member 410 injected with liquid, the second protective member 420 may prevent the first protective member 410 from penetrating between the flexible display 300 and the support housing 350.

[0089] For example, the second protective member 420 may be positioned along at least a portion of the edge of the rear surface of the display panel 330. The second protective member 420 may be disposed in an area of ​​the edge of the rear surface of the display panel 330 other than the area where an adhesive member (e.g., the first adhesive layer 301a) is disposed.

[0090] For example, the second protective member 420 may be positioned along the entire edge of the rear surface of the display panel 330.

[0091] According to an embodiment, the second protective member 420 may be formed using PSA, but this disclosure is not limited thereto. For example, the second protective member 420 may have a predetermined adhesive strength (e.g., tackiness) at room temperature and may be formed using a material that is solid or semi-solid at room temperature. The second protective member 420 may be implemented as, for example, a double-sided adhesive tape having a predetermined adhesive strength. The second protective member 420 may be used interchangeably with adhesive members (e.g., first adhesive layer 301a, second adhesive layer 301b, third adhesive layer 301c).

[0092] According to an embodiment, the second protective member 420 may have various widths, lengths, and thicknesses corresponding to areas of the flexible display 300. For example, if the gap in a predetermined area of ​​the flexible display 300 to which the second protective member 420 is applied is relatively larger than the surrounding area, the thickness of the second protective member 420 applied in that predetermined area may be relatively greater.

[0093] According to an embodiment, at least a portion of the second protective member 420 may be disposed corresponding to the area where a chip-on-plastic (COP) is provided. The COP may include a flexible substrate on which driving circuitry for driving a display driver IC (DDI) for the flexible display 300 is located. A bending portion of the COP may be applied to the area where the COP is bent or folded to the lower part of the flexible display 300, so that the driving circuitry of the electronic device is aligned with the printed circuit board (e.g., Figure 2eThe first plate assembly 261 and / or the second plate assembly 262 are electrically connected. In this case, the second protective member 420 may cover at least a portion of the area where the COP is located.

[0094] According to an embodiment, the flexible display 300 may include at least one adhesive layer 301a, 301b, 301c that bonds at least two or more of the protective layer 310, cover window 320, display panel 330, back cover 340, and support housing 350 together. For example, the flexible display 300 may include a first adhesive layer 301a bonding the protective layer 310 to the cover window 320, a second adhesive layer 301b bonding the cover window 320 to the panel, and a third adhesive layer 301c bonding the panel region 332 to the back cover 340.

[0095] For example, adhesive layers 301a, 301b, and 301c may include pressure-sensitive adhesives (PSAs). To provide the flexible display 300 with bending properties, sliding can occur between the multiple layers included in the flexible display 300. Therefore, when each layer is bonded with a pressure-sensitive adhesive having a low shear modulus and a high elastic limit, the multiple layers of the flexible display 300 can slide relative to each other while being held together by the PSA. Furthermore, adhesive layers 301a, 301b, and 301c may include transparent adhesives, such as optically clear adhesives (OCA), optically clear resins (OCR), or superview resins (SVR).

[0096] Figure 3b This is a rear view showing the flexible display 300 as viewed from the rear direction (e.g., the -z axis direction) according to an embodiment. Therefore, Figure 3b This can be understood as showing a rear view of the support housing 350 as viewed from the rear.

[0097] Reference Figure 3b The support housing 350 ensures the rigidity of the flexible display 300. The support housing 350 may be formed using at least one of metal and plastic or a combination thereof.

[0098] According to an embodiment, the support housing 350 may include a first side frame (e.g., Figure 2a The first side of the first side frame 213 (e.g., Figure 2a The first side 351a corresponds to the first side 213a. The support housing 350 may include a second side 351b connected to one end of the first side 351a and a third side 351c connected to the other end of the first side 351a. The support housing 350 may include a second side 351b connected to one end of the first side 351a and a third side 351c connected to the other end of the first side 351a. Figure 2a The fourth side of the second side frame 223 (e.g., Figure 2a The fourth side 353a corresponds to the fourth side 223a. The support housing 350 may include a fifth side 353b connected to one end of the fourth side 353a and a sixth side 353c connected to the other end of the fourth side 353a.

[0099] According to an embodiment, the support housing 350 may include a COP placement portion 303. The COP placement portion 303 can be understood as a predetermined area corresponding to the support housing 350 when the COP is bent and covers one surface of the support housing 350.

[0100] According to an embodiment, the support housing 350 may include a plurality of holes 370, 380. The plurality of holes 370, 380 may be provided along the side edges of the support housing 350.

[0101] According to embodiments, the plurality of holes 370, 380 may have a circular or elliptical shape. For example, when the plurality of holes 370, 380 are implemented in a circular shape, they may have a diameter of 0.3 mm to 3 mm. For example, when the plurality of holes 370, 380 are implemented in an elliptical shape, they may have a major axis of 0.3 mm to 3 mm.

[0102] According to an embodiment, the plurality of holes 370, 380 may include a first hole 370 and a second hole 380. The first hole 370 may form an inlet for filling the first protective member 410 with liquid. The second hole 380 may form an inlet for light source transmission to cure the first protective member 410. Multiple first holes 370 and multiple second holes 380 may each be provided.

[0103] According to an embodiment, the first hole 370 may be provided near the first side 351a and the fourth side 353a of the support housing 350.

[0104] According to an embodiment, the first hole 370 may be positioned to accommodate the location of electrical components (e.g., camera module or connector) included in the electronic device 200. The first hole 370 may be configured to minimize interference with the electrical components. For example, if the electrical components are mounted near the center of the first side 351a, the first hole 370 may be located near one end and / or the other end of the first side 351a.

[0105] According to an embodiment, the first protective member 410 of the liquid can be cured by a light source (e.g., ultraviolet light) radiated from the front and rear surfaces of the flexible display 300. Due to the repulsive force generated by the cured first protective member 410 during folding, a protective element is positioned along the folding axis (e.g., Figure 2a The first protective member 410 near the folding axis A may interfere with the folding operation of the flexible display 300. Therefore, the thickness of the first protective member 410 needs to be reduced as it gets closer to the folding axis A.

[0106] According to an embodiment, by irradiating a light source through the second hole 380, the first protective member 410 near the folding axis A can be partially cured. Therefore, the thickness of the first protective member 410 can decrease as it gets closer to the folding axis A. (Refer to...) Figure 5 This will be described.

[0107] According to an embodiment, the second hole 380 may be provided near the folding axis A of the second side 351b, the third side 351c, the fifth side 353b, and the sixth side 353c of the support housing 350.

[0108] Figure 4 This is an enlarged cross-sectional view showing a portion of the flexible display 300 and the housing (e.g., side frames 213, 223) according to an embodiment. In other words, Figure 4 It can be understood as from Figure 3b The cross-sectional view observed at B-B'.

[0109] Reference Figure 4 The flexible display 300 can be made of a support plate (e.g., Figure 2e The flexible display 300 is supported by a first support plate and a second support plate 2131. The flexible display 300 can be disposed in the space formed by the side frames 213, 223. To provide sliding during bending of the flexible display 300, a gap with a predetermined distance can exist between the space formed by the side frames 213, 223 and the support plates 2131, 2231 and the side surface of the flexible display 300. For example, this gap can have a predetermined width w. The predetermined width w can be, for example, about 0.5 mm. Because the multiple layers included in the flexible display 300 have different lengths or widths, the predetermined width w can vary corresponding to the height.

[0110] According to an embodiment, the first protective member 410 can prevent foreign objects from intruding through the gap. The first protective member 410 can be disposed between the side surface of the flexible display 300 and the side frames 213, 223. The first protective member 410 can closely contact the area including the space formed between the side surface of the flexible display 300 and the side frames 213, 223. Therefore, the first protective member 410 can close the path through which foreign objects are introduced into the gap.

[0111] According to an embodiment, the first protective member 410 may include a polymer material. Because the first protective member 410 is formed using a polymer material, in the event of bending of the flexible display 300, the first protective member 410 can bend while maintaining close contact with a region on the side surface of the flexible display. During the bending of the flexible display 300, multiple layers included in the flexible display 300 (e.g., Figure 3aThe cover window 320 or display panel 330 can be bent at different curvatures while causing sliding between them. The polymer material of the first protective member 410 can have the elasticity and elongation to be bent while maintaining close contact with the multiple layers of the flexible display 300 as described above.

[0112] According to an embodiment, the first protective member 410 may be formed using a polymer material having a predetermined dielectric constant and a predetermined dielectric loss. The dielectric constant of the polymer material may be, for example, 3.5 or less. The dielectric loss of the polymer material may be 0.02 or less. Due to the use of a polymer material with a predetermined dielectric constant and a predetermined dielectric loss, the degradation of antenna performance caused by the side frames 213, 223 formed using metallic materials can be minimized.

[0113] According to the embodiments, close contact of the first protective member 410 can be understood as the first protective member 410 being bonded and / or attached. For example, the first protective member 410 may be bonded to a region including the space between the cover window 320 and the display panel 330 on the side surface of the flexible display 300. For example, the first protective member 410 may fill the region including the space between the cover window 320 and the display panel 330 on the side surface of the flexible display 300 by the adhesiveness of a polymer material.

[0114] According to an embodiment, the first protective member 410 may closely contact an area including the space between the lower portion of the protective layer 310 and the upper surface of the display panel 330. A gap may exist in this area to allow sliding between the protective layer 310 and the cover glass 320. The first protective member 410 closely contacts the area where the gap exists, thereby reducing damage to the display panel 330 or the cover glass caused by foreign objects introduced during bending operations.

[0115] According to an embodiment, the first protective member 410 can be passed through the first hole 370 (e.g., Figure 3b Injection through the first orifice 370. Injection device (e.g., Figure 8 The first protective member 370 (dispensing nozzle 840) can inject liquid through the first hole 370. The liquid first protective member 410 can be injected through the first hole 370 and flows along the path between the flexible display 300 and the side frames 213, 223 and fills the space forming the gap. For example, in order to make the first protective member 410 have a predetermined fluidity in the liquid state, the first protective member 410 can be formed using a flexible material with low viscosity and high tensile strength.

[0116] For example, the first protective member 410 may have a predetermined viscosity. The first protective member 410 may have a viscosity of, for example, 1000 cPs to 10000 cPs in the solution state.

[0117] According to an embodiment, the first protective member 410 may have a predetermined elasticity and a predetermined elongation.

[0118] According to an embodiment, polymer material can be injected through the first hole 370 into the gap between the flexible display 300 and the side frames 213, 223. The polymer material solution can be injected via a spraying process such as jetting or dispensing. Subsequently, the polymer material can be cured by one or more of the following curing methods: photocuring by a light source, thermal curing by heat, room temperature curing, or moisture curing.

[0119] According to an embodiment, the polymer material constituting the first protective member 410 can be introduced through the first hole 370 and flow along the side edge of the flexible display 300. To facilitate the flow of the introduced polymer material, the portions of the inner sides of the side frames 213, 223 facing the side surface of the flexible display 300 can be curved, and this can be referred to as a flow channel 350a. Due to the flow channel 350a, the polymer material can easily move along a path formed through the gap near the edge of the electronic device 200.

[0120] According to an embodiment, the flow channel 350a may be formed on at least a portion of the path formed by the gap. For example, the flow channel 350a may be formed only near the first hole 370, at a point where the width of the path narrows, or along the entire path. The flow channel 350a may be formed taking into account the fluidity of the polymer material itself and the flow resistance of the polymer material flowing in the path.

[0121] According to an embodiment, the first protective member 410 may have a first surface 415 corresponding to the front surface of the flexible display 300 and a second surface 417 corresponding to the rear surface of the flexible display 300. The thickness t of the first protective member 410 may be defined as the distance between the first surface 415 and the second surface 417.

[0122] According to an embodiment, the second surface 417 of the first protective member 410 may be determined by the volume of polymer material injected through the first hole 370. For example, the second surface 417 may be located at substantially the same height as the lower surface of the second protective member 420.

[0123] According to an embodiment, the height or shape of the first surface 415 of the first protective member 410 may be determined by the engaging protrusion 340 provided on the fixing pad 700, which will be described below. The height of the first surface 415 may be determined by the height of the engaging protrusion 340 provided on the fixing pad 700. The shape of the first surface 415 may be determined by the shape of the engaging protrusion 340 provided on the fixing pad 700. For example, the first surface 415 may be flat or curved in a rearward direction. (Refer to...) Figure 8 This will be described below.

[0124] According to an embodiment, the first surface 415 of the first protective member 410 may be located at a height relative to or at the same height as the top of the flexible display 300. In other words, the thickness t of the first protective member 410 may be less than or equal to the thickness h of the flexible display 300 and the second protective member 420. The relationship between t and h can be defined as follows: 1 / 2h ≤ t ≤ h.

[0125] According to an embodiment, when the first surface 415 of the first protective member 410 is located relatively below the top of the flexible display 300, the first protective member 410 can prevent foreign objects from being introduced into the gap while ensuring the space required to allow sliding to occur in the flexible display 300.

[0126] According to an embodiment, the height t of the first protective member 410 can be determined by taking into account the degree of deformation caused by sliding in the flexible display 300. For example, in areas where the degree of deformation caused by sliding in the flexible display 300 is large, the height of the first protective member 410 can be reduced.

[0127] For example, the first surface 415 may be located at substantially the same height as the lower surface of the protective layer 410. The first protective member 410 may be configured to correspond at the height of the upper surface of the cover window 320 on the side surface of the flexible display 300.

[0128] For example, the first surface 415 may be located at substantially the same height as the ultrathin glass included in the cover window 320.

[0129] According to an embodiment, the second protective member 420 may be configured to prevent the polymer material constituting the first protective member 410 from flowing and penetrating into the rear surface of the flexible display 300. The second protective member 420 may be disposed along the edge of the rear surface of the flexible display 300.

[0130] According to an embodiment, a second protective member 420 may be disposed between the support housing 350 and the display panel 330. The second protective member 420 may be disposed along the edge of the display panel 330 in the rearward direction. The second protective member 420 may seal the area formed between the support housing 350 and the display panel 330 (e.g., a gap of predetermined thickness). Therefore, in the case of a first protective member 410 injected with liquid, the second protective member 420 may prevent the first protective member 410 from penetrating between the flexible display 300 and the support housing 350.

[0131] According to an embodiment, the second protective member 420 may be formed using PSA, but this disclosure is not limited thereto. For example, the second protective member 420 may have a predetermined adhesive strength (e.g., tackiness) at room temperature and may be formed using a material that is solid or semi-solid at room temperature. The second protective member 420 may be implemented as, for example, a double-sided adhesive tape having a predetermined adhesive strength. The second protective member 420 may be used interchangeably with adhesive members (e.g., first adhesive layer 301a, second adhesive layer 301b, third adhesive layer 301c).

[0132] According to an embodiment, the second protective member 420 may have various widths, lengths, and thicknesses corresponding to areas of the flexible display 300. For example, if the step in a predetermined area of ​​the flexible display 300 to which the second protective member 420 is applied is relatively larger than the surrounding area, the thickness of the second protective member 420 applied in that predetermined area may be relatively greater.

[0133] Figure 5 This is an enlarged cross-sectional view showing a portion of the first protective member 410 and the housing (e.g., side frames 213, 223) according to an embodiment. In other words, Figure 5 It can be understood as from Figure 3b The cross-sectional view observed at C-C'.

[0134] Reference Figure 5 The two opposite sides of the first protective member 410 may be based on the folding axis A (e.g., Figure 2a The folding axis A) is symmetrical.

[0135] According to an embodiment, the first protective member 410 may have a substantially uniform thickness. However, the first protective member 410 may have a reduced thickness near the folded area. The first protective member 410 may include a first-1 protective member 413 located near the folded area. The first protective member 410 may include a first-2 protective member 411 adjacent to the first-1 protective member 413.

[0136] According to an embodiment, the first-1 protective member 413 may include a first surface 416 corresponding to the front surface of the flexible display 300. The first-1 protective member 413 may include a second surface 418 corresponding to the rear surface of the flexible display 300.

[0137] According to an embodiment, the first-second protective member 411 may include a first surface 415 corresponding to the front surface of the flexible display 300. The first surface 415 may be substantially the same as the first surface 415 of the first protective member 410. The first-second protective member 411 may include a second surface 417 corresponding to the rear surface of the flexible display 300. The second surface 417 may be substantially the same as the second surface 417 of the first protective member 410.

[0138] According to an embodiment, due to the repulsive force of the polymer material constituting the first protective member 410, the first protective member 410 near the folding area may degrade the folding performance of the electronic device 200. Therefore, the first protective member 410 may be configured to reduce the area it occupies near the folding area.

[0139] For example, the first protective member 413 may not be present in the region corresponding to the folding axis A. In other words, the space formed by the gap may be empty in this region.

[0140] According to an embodiment, the first protective member 413 may have a decreasing thickness as it approaches the folding axis A. The height of the first protective member 413 at the first surface 416 is constant, while the thickness at the second surface 418 may decrease as it approaches the folding axis A, thus becoming adjacent to the first surface 416. Therefore, when the electronic device 200 is viewed from the front, the first protective member 410 appears to extend into the folding area, thereby providing aesthetics.

[0141] According to an embodiment, the height of the second surface 418 of the first-1 protective member 413 can be determined by passing through the second hole 380 (e.g., Figure 3b The curing of the first-1 protective member 413 is controlled by the light source radiating through the second hole 380. When the light source for curing the first-1 protective member 413 radiates through the second hole 380, the first-1 protective member near the second hole 380 is partially cured, and the second surface 418 can be configured to be inclined. (Refer to...) Figure 9 This will be described.

[0142] Figure 6 This is a manufacturing process diagram according to an embodiment for filling the gap formed between the flexible display 300 and the housing (e.g., side frames 213, 223) with a first protective member 410.

[0143] Reference Figure 6 In step 610, the placement pad (e.g., Figure 7 The mounting pad 700 is set in the lower clamp (e.g., Figure 8 The lower clamp 810 is used as a fixture. A space for the placement pad 700 can be formed in the lower clamp 810. This space can be at least partially recessed or cut to allow the placement pad 700 to be placed. The placement pad 700 can be fixed in this space.

[0144] According to an embodiment, in step 620, the display assembly can be attached to the mounting pad 700. Here, the display assembly is a structure in which the flexible display 300 is partially attached to the side frames 213, 223, and can be understood as a semi-assembled structure of the electronic device 200 for filling the first protective member 410.

[0145] According to an embodiment, the display assembly can be joined such that the front surface of the display assembly (e.g., the front surface of the flexible display 300) faces the mounting pad 700. When the display assembly and the mounting pad 700 are assembled, a mounting portion (e.g., ...) is provided in the mounting pad 700. Figure 7 The engagement protrusion 740 on the mounting portion 730 can engage with the gap formed along the edge of the flexible display 300.

[0146] According to an embodiment, in step 630, the lower clamp 810 can be connected to the upper clamp (e.g., Figure 8 The upper clamp 820) is used for fastening. When the display assembly is positioned between the lower clamp 810 and the upper clamp 820, they can be secured by fastening members (e.g., Figure 8 The fastening member 830 is fastened. According to an embodiment, the upper clamp 820 may include a plurality of holes. When the lower clamp 810 and the upper clamp 820 are fastened, the plurality of holes may be positioned to correspond to the first hole 730 and the second hole 380.

[0147] According to an embodiment, in step 640, a filling member can be injected. The filling member can be, for example, a polymeric material of liquid constituting the first protective member 410. The polymeric material can be injected from an injection nozzle (e.g., Figure 8 The polymer material is sprayed through an injection nozzle 840, passes through a hole in the upper clamp 820, and is introduced through a first hole 730. The polymer material can flow through the path formed by the gaps.

[0148] According to an embodiment, in step 650, the filler component can be cured. The liquid polymer material can be cured by a light source, heat source, or moisture radiated from the front or rear direction of the fixture. While the polymer material is curing near the second hole 380, one surface of the first protective component 410 (e.g., Figure 5 The second surface 418 can be set to be inclined, and the thickness of the first protective member 410 can be reduced.

[0149] Figure 7 This is a perspective view showing the placement pad 700 according to an embodiment.

[0150] Reference Figure 7 The mounting pad 700 guides the display assembly to facilitate filling the first protective member 410. The display assembly is a state in which the flexible display 300 is combined with a portion of the side frames 213, 223, and can be understood as a semi-assembled electronic device 200 for filling the first protective member 410 in the gap formed between the flexible display 300 and the side frames 213, 223.

[0151] According to an embodiment, the front surface of the display assembly can be bonded to face the mounting pad 700.

[0152] According to an embodiment, the mounting pad 700 may be formed using a flexible material with low stiffness and high tensile strength to ensure airtightness with the display assembly. For example, the mounting pad 700 may be formed using silicone, polyurethane, or rubber.

[0153] According to an embodiment, in order for a light source (e.g., UV) used to cure the first protective member 410 to transmit through the mounting pad 700, the mounting pad 700 may be formed using a material having a predetermined light transmittance. The predetermined light transmittance, for example, a light density value may be less than or equal to 1.

[0154] According to an embodiment, the mounting pad 700 may include a mounting portion 730, a frame 720 surrounding the outer edge of the mounting portion 730, and a fixing guide 710 for fixing the corner of the display assembly.

[0155] According to an embodiment, the fixing guide 710 can be disposed at the four corners of the mounting pad 700. The height of the fixing guide 710 can be substantially the same as the height of the display assembly.

[0156] According to an embodiment, the frame 720 can secure the display assembly to the mounting pad 700. The inner side of the frame 720 may correspond to the outer edge of the side frames 213, 223 included in the display assembly.

[0157] According to an embodiment, the mounting portion 730 may provide an area for mounting at least a portion of the front surface of the display assembly.

[0158] According to an embodiment, the mounting portion 730 may include a coupling protrusion 740. The coupling protrusion 740 may engage with a gap in the display assembly. The shape of the first surface 415 of the first protective member 410 may be determined based on the shape of the coupling protrusion 740.

[0159] According to the embodiments, the cross-section of the protrusion 740 can be formed into a circular shape, an elliptical shape, a rectangular shape, etc., and can be implemented with multiple steps to achieve higher adhesion when placed together with the front surface of the display assembly.

[0160] According to an embodiment, a barrier structure may be provided in a predetermined area of ​​the placement portion 730 corresponding to the folding area of ​​the flexible display 300. The barrier structure can prevent the first protective member 410 from overflowing into the folding area. The barrier structure may be formed, for example, at a point corresponding to the folding axis A of the flexible display 300.

[0161] Figure 8 This is a cross-sectional view showing a display assembly fixed to a clamping device according to an embodiment. Figure 8 It shows Figure 6 Step 640, and can be understood as a cross-sectional view near the first hole 370 included in the electronic device 200.

[0162] Reference Figure 8 Placement pads (e.g., Figure 7 A mounting pad 700 may be disposed on the upper side of the lower clamp 810. A display assembly may be attached to the upper side of the mounting pad 700. When the mounting pad 700 and the display assembly are attached, a connecting protrusion 740 included in the mounting pad 700 may engage with a gap formed along the side edge of the flexible display 300. The connecting protrusion 740 is substantially in close contact with this gap, and the height or shape of the first surface 415 of the first protective member 410 may be uniformly provided. The shape of the first surface 415 of the first protective member 410 may be determined according to the shape of the connecting protrusion 740.

[0163] According to an embodiment, a liquid polymer material can be introduced from an injection nozzle 840 and sprayed into gaps formed on the edge of the flexible display 300.

[0164] According to an embodiment, the flow channel 350a can provide a wide flow path to facilitate the flow of liquid polymer materials. The flow channel 350a can be formed by bending a portion of the inner side surface of the side frames 213, 223 facing the flexible display 300.

[0165] According to an embodiment, the flow channel 350a may be formed on at least a portion of the path formed by the gap. For example, the flow channel 350a may be formed only near the first hole 370, at a point where the width of the path narrows, or along the entire path. The flow channel 350a may be formed taking into account the fluidity of the polymer material itself and the flow resistance of the polymer material flowing in the path.

[0166] Figure 9 This is a cross-sectional view showing a display assembly fixed to a clamping device according to an embodiment. Figure 9 It shows Figure 6 Step 650, and can be understood as showing a cross-sectional view near the second hole 380 included in the electronic device 200.

[0167] Reference Figure 9 The first protective member 410 can be formed by solidifying a liquid polymer material. The liquid polymer material can flow along the fold axis A. For example, the polymer material can flow in the order of ①, ②, and ③.

[0168] According to an embodiment, UV light S can be radiated through the second hole 380. The first protective member 410, which is closer to the second hole 380, can cure faster and has a slower flow rate. Therefore, the second surface of the first protective member 410 adjacent to the second hole 380 (e.g., Figure 5 The second surface 418 can be configured relative to the first surface (e.g., Figure 5The first surface (416) is inclined.

[0169] According to the embodiment, the first protective component 410 can be cured not only by a light source, but also by a heat source, room temperature curing or moisture curing.

[0170] Figure 10 The shape of the first surface 415 of the first protective member 410 according to an embodiment is shown.

[0171] Reference Figure 10 The first surface 415 of the first protective member 410 may be provided by a mounting member (e.g., Figure 7 The shape of the connecting protrusion 740 on the mounting component 700 is determined.

[0172] According to an embodiment, the first surface 415 may be flat or curved. When the first surface 415 is curved, it may be curved in a rearward direction.

[0173] For example, when the first surface 415 is bent, the first surface 415-1 of the first protective member 410 can be bent symmetrically from left to right.

[0174] For example, if the first surface 415 is bent, the first surface 415-2 of the first protective member 410 can be bent to the left.

[0175] For example, if the first surface 415 is bent, the first surface 415-3 of the first protective member 410 may be bent to the right.
