[0032] Figure 1A This is a front perspective view showing an electronic device 100 in a closed state according to an embodiment. Figure 1B This is a rear perspective view showing an electronic device 100 in a closed state according to an embodiment.

[0033] Reference Figure 1A , Figure 1B , Figure 2A and Figure 2B In one embodiment, the electronic device 100 may be configured to extend the screen in a sliding manner. Figure 1A and Figure 1B The electronic device 100 is shown in a state where the screen 1301 is not extended. Figure 2A and Figure 2B An electronic device 100 is shown in an extended state of screen 1301. The unextended state of screen 1301 is the state in which the sliding plate 120, which enables the flexible display 130 to slide, is not extended, and may be referred to hereinafter as the "closed state". The extended state of screen 1301 is the maximum extended state in which screen 1301 no longer extends due to the sliding of the sliding plate 120, and may be referred to hereinafter as the "open state". According to various embodiments, the open state may be defined as the extended state of screen 1301 compared to the closed state, and various screen sizes may be provided depending on the movement position of the sliding plate 120. Screen 1301 is the effective area of ​​the flexible display 130 that is visually exposed to output images, and the electronic device 100 may adjust the effective area according to the movement of the sliding plate 120 or the flexible display 130. In the following description, the open state may refer to the state in which screen 1301 is extended to its maximum extent. In some embodiments, in Figure 1A The flexible display 130 in the electronic device 100, which is configured to slide to provide a screen 1301, may be referred to as a "slide-out display" or "expandable display".

[0034] According to an embodiment, the electronic device 100 may include a sliding structure based on an elastic structure associated with the flexible display 130. When the flexible display 130 moves a predetermined distance by an external force, the flexible display 130 can switch from a closed state to an open state or from an open state to a closed state without any other external force due to the elastic structure.

[0035] According to some embodiments, when a signal is generated by an input device included in the electronic device 100, the electronic device 100 can switch from a closed state to an open state or from an open state to a closed state because of a driving device (such as a motor) connected to the flexible display 130. For example, when a signal is generated by a hardware button or software button provided on the screen, the electronic device 100 can switch from a closed state to an open state or from an open state to a closed state.

[0036] According to various embodiments, when a signal is generated from various sensors such as pressure sensors, the electronic device 100 can switch from a closed state to an open state or from an open state to a closed state. For example, when the electronic device 100 is carried or held by hand, a squeezing gesture of a part of the hand (e.g., the bottom of the hand or fingers) pressing on a designated part of the electronic device 100 can be detected by a sensor, and the electronic device 100 can switch from a closed state to an open state or from an open state to a closed state in response to this.

[0037] According to an embodiment, the flexible display 130 may include a bendable portion ③ (see embodiment 3). Figure 2A When the electronic device 100 switches from a closed state to an open state, the flexible portion ③ provides an extension of the screen 1301. When the electronic device 100 switches from a closed state to an open state, the flexible portion ③ is pulled out from the internal space of the electronic device 100; therefore, the screen 1301 can be extended. When the electronic device 100 switches from an open state to a closed state, the flexible portion ③ slides into the internal space of the electronic device 100; therefore, the screen 1301 can be reduced in size. When the electronic device 100 switches from an open state to a closed state, the flexible portion ③ can be moved into the internal space of the electronic device 100 while being bent. The flexible display 130 can be implemented based on a flexible substrate (e.g., a plastic substrate) made using a polymer material including polyimide (PI) or polyester (PET).

[0038] According to an embodiment, the electronic device 100 may include a housing 110, a sliding plate 120, and / or a flexible display 130.

[0039] The housing (or outer casing) 110 may include, for example, a rear cover 112, a first side cover 113, and / or a second side cover 114. The rear cover 112, the first side cover 113, and / or the second side cover 114 may be connected to a support member (not shown) located inside the electronic device 100 and form at least a portion of the appearance of the electronic device 100.

[0040] The back cover 112 may form at least a portion of, for example, the rear surface 100B of the electronic device 100. The back cover 112 may be substantially opaque. The back cover 112 may be made of coated or colored glass, ceramic, polymer, metal (e.g., aluminum, stainless steel (STS), or magnesium), or a combination of at least two of the above materials. According to various embodiments, at least a portion of the back cover 112 may be transparent or include openings, and...

[0041] According to an embodiment, the back cover 112 may include a flat portion 112a and curved portions 112b and 112c positioned opposite each other, with the flat portion 112a located between them. The curved portions 112b and 112c may be formed adjacent to two long sides (not shown) of the back cover 112, respectively, and may be curved and extend seamlessly toward a screen 1301 disposed opposite to the back cover 112. According to some embodiments, the back cover 112 may include one of the curved portions 112b and 112c, or may be implemented without the curved portions 112b and 112c.

[0042] According to an embodiment, a first side cover 113 and a second side cover 114 may be disposed opposite to each other. The first side cover 113 may form a first side surface 113a of the electronic device 100, and the second side cover 114 may form a second side surface 114a of the electronic device 100 facing a direction opposite to the first side surface 113a. The first side cover 113 may include a first edge (or first edge) 113b extending from the edge of the first side surface 113a, and the first edge 113b may at least partially form a side frame of the electronic device 100. The second side cover 114 may include a second edge (or second edge) 114b extending from the edge of the second side surface 114a, and the second edge 114b may at least partially form another side frame of the electronic device 100. According to an embodiment, in Figure 1AIn the closed state, the surfaces of the first edge 113b, the second edge 114b, and the sliding plate 120 can be smoothly connected to form a curved portion (not shown) corresponding to the first curved portion 130b of the screen 1301. According to various embodiments, the surfaces of the first edge 113b and / or the second edge 114b may include a curved portion (not shown) on the other side of the screen 1301 corresponding to the side of the second curved portion 130c disposed opposite to the first curved portion 130b.

According to embodiments, the adhesive member may include a heat-reactive adhesive, a photoreactive adhesive, a universal adhesive, and / or double-sided tape. According to various embodiments, the flexible display 130 can be slidably inserted into a recess (not shown) formed in the sliding plate 120 to set and secure it to the sliding plate 120. The sliding plate 120 is used to support the flexible display 130; according to some embodiments, the sliding plate 120 may be referred to as a slidable support plate.

[0044] According to an embodiment, the sliding plate 120 may include a third edge 120b forming the outer surface of the electronic device 100, and Figure 1A In the closed state, the third edge 120b, together with the first edge 113b and the second edge 114b, can form a border around the screen. Figure 1A In the closed state, the surface of the third edge 120b can be smoothly connected to the surface of the first edge 113b and / or the surface of the second edge 114b.

[0045] The flexible display 130 can be formed, for example, a screen 1301 disposed opposite to the back cover 112. Due to the sliding of the sliding plate 120, at least a portion of the flexible portion ③ can provide an expanded state (e.g., an open state) for the screen 1301 when it is removed from the interior of the electronic device 100, such as...

The first curved portion 130b and the second curved portion 130c may be substantially symmetrical to each other with respect to the flat portion 130a located between them. Figure 1A In the closed state, the first curved portion 130b and the second curved portion 130c can be positioned as curved portions 112b and 112c respectively corresponding to the rear cover 112 and can be bent toward the rear cover 112. When the electronic device 100 is in the closed state... Figure 1A Switching to the closed state Figure 2A When in the open state, the flat portion 130a can be expanded. For example, when the electronic device 100 is in the open state... Figure 1A Switching to the closed state Figure 2A When in the open state, the flexible part ③ is... Figure 1A At least a portion of the area forming the second curved portion 130c in the closed state may be included in the extended flat portion 130a, and may be formed as another area of ​​the flexible portion ③.

[0100] According to an embodiment, the base film 620 may be disposed along the junction ⑤ of the first portion ①, the flexible portion ③, and the second portion ②. For example, the base film 620 may include a first portion 621 disposed along the first portion ① and the flexible portion ③, and a second portion 622 disposed along the junction ⑤ of the second portion ②. The base film 620 may not be disposed in the folded portion ④ of the second portion ②, which may contribute to the flexibility of the folded portion ④.

[0101] According to an embodiment, FPCB 137 may be electrically connected to display panel 610 in bonding portion ②. Extension portion 614 of display panel 610 may be electrically connected to FPCB 137. For example, FPCB 137 may be electrically connected to extension portion 614 based on anisotropic conductive film bonding (ACF bonding). ACF may be an anisotropic conductive film formed by mixing fine conductive particles (e.g., Ni, carbon, or solder balls) with an adhesive resin (e.g., thermosetting resin) to form a film state and conducting electricity in only one direction. When the ACF is placed between FPCB 137 and extension portion 614 and then compressed by applying heat and pressure, the conductive pattern (not shown) formed in extension portion 614 may be electrically connected to the conductive pattern formed in FPCB 137 via the conductive particles, and the adhesive resin may bond extension portion 614 and FPCB 137 to each other. Electrical paths included in extension portion 614 may electrically connect at least one TFT and FPCB 137. For example, electrical paths may be formed in TFT film 612 together with the TFT based on LTPS, LTPO, or a-Si. FPCB 137 can be electrically connected to flexible display 130 by various other methods (e.g., connections between connectors). One end of FPCB 137 (not shown) can be electrically connected to flexible display 130, and the other end of FPCB 137 (not shown) can be electrically connected to... Figure 3 , Figure 4 or Figure 5PCB 390. FPCB 137 may include connector 137a for electrical connection to PCB 390.

[0102] According to an embodiment, the display driving circuit 640 may be disposed in the second part ② of the flexible display 130. Processor (e.g., application processor (AP)) (e.g., Figure 18 The processor 1820 can be set to Figure 3 , Figure 4 or Figure 5 At PCB 390, and the processor command signal can be transmitted to the display driver circuit 640 via FPCB137. According to an embodiment, the display driver circuit 640 may be located at the extension 614 of the display panel 610, such as... Figure 6A As shown in the diagram (e.g., chip-on-film (COP) method). According to some embodiments (not shown), the display driving circuit 640 may be disposed in the display assembly 600 using a chip-on-film (COF) method. The COF method may have a structure in which the display driving circuit 640 is disposed at a separate flexible film substrate that electrically connects the lower panel 630 and the FPCB 137. In the COF method, the flexible film substrate and the FPCB 137 can be connected by ACF bonding. According to various embodiments, the display driving circuit 640 may be disposed in an extension 614 of the display panel 610 (or the flexible film substrate in COF) by tape auto-bonding (TAB).

[0103] According to an embodiment, the display driving circuit 640 can be electrically connected to the FPCB 137 and TFT in the flexible display 130 via an electrical path included in the extension portion 614 of the display panel 610. According to an embodiment, the display driving circuit 640 can be used to connect the flexible display 130 to the FPCB 137 and TFT disposed in the flexible display 130. Figure 3 , Figure 4 or Figure 5 The signal path between the processor at PCB 390 is used to control pixels via TFTs within the flexible display 130. For example, the display driving circuit 640 may have the function of turning pixels included in the flexible display 130 on or off and may be electrically connected to the gate electrode of the TFT. The display driving circuit 640 may have the function of generating color difference by adjusting the amount of red, green, and blue (RGB) signals of the pixels and may be electrically connected to the source electrode of the TFT. The TFT may include gate lines electrically connected to the display driving circuit 640 and its gate electrodes, and source lines (or data lines) electrically connected to the display driving circuit 640 and its source electrodes. According to various embodiments, the display driving circuit 640 may operate in a red, green, blue, and white (RGBW) method corresponding to white pixels being added to RGB pixels.

[0104] According to some embodiments (not shown), the display driver circuit 640 may be located at FPCB 137.

[0105] According to various embodiments, the display driver circuit 640 may be a DDI package. The DDI package may include a DDI (or a DDI chip), a timing controller (T-CON), graphics RAM (GRAM), or power generation circuitry. According to various embodiments, the graphics RAM may be omitted, or a memory separate from the display driver circuit 640 may be used. The timing controller converts data signals input from the processor into signals required in the DDI. The timing controller functions to adjust input data information into signals suitable for the gate drivers (or gate ICs) and source drivers (or source ICs) of the DDI. The graphics RAM can be used as a memory for temporarily storing data to be input to the DDI driver (or IC). The graphics RAM can store input signals and send them back to the DDI driver, which can process the signals by interacting with the timing controller. The power driver generates the voltage to drive the flexible display 130 and supplies the required voltage to the gate drivers and source drivers of the DDI.

[0106] Reference Figure 6A In one embodiment, the flexible display 130 may include a border region 136a formed adjacent to its edge 136. The border region 136a may not include pixels implemented using light-emitting devices such as OLEDs, and may include, for example, a black material or black base material having relatively low light transmittance. The border region 136a may be implemented by coating or printing a light-shielding material onto a transparent cover protecting the flexible display 130. Figure 2A In the open state, the bezel area 136a can be positioned between the screen 1301 and the sliding mechanical structure surrounding the screen 1301 to help improve the aesthetic appearance of the electronic device 100. In an embodiment, in Figure 1A In the closed state, a border region for allowing the flexible portion ③ to enter or exit may not exist on the opening (not shown) side, but in various embodiments, the border region can be implemented by a software method. The software method for the border region can be implemented, for example, by not activating a portion of the flexible display 130 or by displaying an image in a portion of the flexible display 130. According to various embodiments, the flexible display 130 can be implemented to minimize or substantially eliminate the border region 136a. In this case, the mechanical structure around the screen 1301 can be implemented as a slim form factor that can slide out without degrading the aesthetic appearance, or in some cases, the border region can be targeted at… Figure 1A The closed state or Figure 2AThe open state is implemented using a software method. According to various embodiments, the signal lines and / or touch screen panel (TSP) electrodes of the flexible display 130 may be disposed in the bezel area 136a.

[0107] Figure 7 This is a cross-sectional view showing a portion of a display assembly 700 according to an embodiment.

[0108] Reference Figure 7 In this embodiment, the display assembly 700 may include a display panel 610, a base film 620, a lower panel 630, a display driving circuit 640, an FPCB 137, a transparent cover 710, an optically transparent adhesive member 720, an optical layer 730, a support sheet 370, and / or a spacer 740. The base film 620 may include a first portion 621 located in a first portion ① of the flexible display 130 and a second portion 622 located in a second portion ② of the flexible display 130. (The remaining text is omitted.) Figure 7 Redundant descriptions of some of the figure labels.

[0109] According to an embodiment, the flexible display 130 may be disposed in Figure 3 , Figure 4 or Figure 5 A screen is formed at the sliding plate 120, comprising a flat portion 130a and a first curved portion 130b extending from the flat portion 130a. The first portion ① of the flexible display 130 may be disposed along the flat portion 130a and the first curved portion 130b. The second portion ② of the flexible display 130 may include a folded portion ④ and a joining portion ⑤. For example, the folded portion ④ may be bent with a corresponding radius of curvature R, and the joining portion ⑤ may be disposed overlapping the first portion ①. The display panel 610 may be disposed along the first portion ① and the second portion ②. The first portion 621 of the base film 620 may be disposed along the first portion ①, and the second portion 622 of the base film 620 may be disposed along the joining portion ⑤ of the second portion ②.

[0110] According to an embodiment, the display driving circuit 640 may be disposed in the second part ②. For example, the display driving circuit 640 may be disposed at the extension 614 of the display panel 610, and may be disposed at least partially superimposed on the flat portion 130a. The FPCB 137 may be electrically connected to the extension 614 of the display panel 610. Because Figure 1A The electronic device 100 is implemented to slide out the sliding plate 120 on which the display assembly 700 is provided. Therefore, in order not to interrupt such sliding operation, the display driving circuit 640 bends the folding portion ④ at the side of the first bending portion 130b to be disposed in the joint portion ⑤ between the first portion ① and the sliding plate 120, as shown. Figure 6A or Figure 7 As in the embodiments.

[0111] According to an embodiment, a transparent cover (or window) 710 may cover the display panel 610 of the flexible display 130. The transparent cover 710 protects the flexible display 130 from external influences and may be implemented in the form of a thin film (e.g., a thin film layer) that contributes to flexibility. According to an embodiment, the transparent cover 710 may comprise a plastic film (e.g., a polyimide film) or a thin-film glass (e.g., ultra-thin glass (UTG)). An optical layer 730 may be interposed between the transparent cover 710 and the display panel 610.

[0112] According to various embodiments (not shown), the transparent cover 710 may include multiple layers. For example, the transparent cover 710 may have various coatings disposed in a plastic film or thin-film glass. For example, the transparent cover 710 may have at least one protective layer or coating comprising a polymer material (e.g., polyester (PET), polyimide (PI), or thermoplastic polyurethane (TPU)) disposed in a plastic film or thin-film glass.

[0113] According to various embodiments, the transparent cover 710 may be implemented with a relatively thin thickness in the flexible portion ③. For example, at least one of the plurality of layers of the transparent cover 710 may not extend at least partially into the flexible portion ③ compared to at least one other layer. According to some embodiments, the transparent cover 710 may be implemented with a relatively thin thickness in at least a portion of the portion corresponding to the first curved portion 130b. In this case, the optically transparent adhesive member 720 between the optical layer 730 and the transparent cover 710 may be in the form of... Figure 7 Different forms (e.g., different thicknesses) are provided in the portion corresponding to the first curved portion 130b in the embodiments.

[0114] Optical layer 730 may include, for example, a polarizing layer (or polarizer) or a phase retardation layer (or retarder). The polarizing layer and phase retardation layer improve the outdoor visibility of the screen. According to embodiments, optical layer 730 selectively allows light generated from a light source of display panel 610 and vibrating in a predetermined direction to pass through. According to various embodiments, a single layer combining a polarizing layer and a phase retardation layer may be provided, and such a layer may be defined as a “circularly polarized layer.” Optically clear adhesive member 720 may be located between transparent cover 710 and optical layer 730, and may include, for example, optically clear adhesive (OCA), optically clear resin (OCR), or super-long-range resin (SVR). According to various embodiments, the polarizing layer (or circularly polarized layer) may be omitted; in this case, a black pixel defining layer (PDL) and / or a color filter may be provided instead of the polarizing layer.

[0115] According to various embodiments (not shown), the display assembly 700 may include touch sensing circuitry (e.g., a touch sensor). The touch sensing circuitry may be implemented as a transparent conductive layer (or film) based on various conductive materials, such as indium tin oxide (ITO). According to one embodiment, the touch sensing circuitry may be disposed between the transparent cover 710 and the optical layer 730 (e.g., add-on type). According to another embodiment, the touch sensing circuitry may be disposed between the optical layer 730 and the display panel 610 (e.g., on-cell type). According to another embodiment, the display panel 610 may include touch sensing circuitry or touch sensing functionality (e.g., in-cell type).

[0116] According to various embodiments (not shown), the display panel 610 may be formed based on an OLED and may include a display panel disposed on an OLED. Figure 6B The light-emitting layer 611 and Figure 7 Encapsulation 613 between optical layers 730 (see Figure 6B (e.g., a thin-film encapsulation (TFE)). For example, encapsulation 613 can be used as a pixel protection layer for protecting a plurality of pixels of the light-emitting layer 611. According to various embodiments (not shown), flexible display 130 is a touch sensing circuit disposed at encapsulation 613 between encapsulation 613 and optical layer 730, and may include a conductive pattern such as a metal mesh (e.g., an aluminum mesh). For example, in response to bending of flexible display 130, the durability of the metal mesh may be greater than that of a transparent conductive layer implemented with ITO.

[0117] According to various embodiments (not shown), the flexible display 130 may also include a pressure sensor capable of measuring touch intensity (pressure).

[0118] According to various embodiments, some of the multiple layers included in the lower panel 630 may include a digitizer for detecting a pen input device (e.g., a stylus). The digitizer may be, for example, an electromagnetic induction panel for sensing a magnetic field-type pen input device. According to various embodiments, the electromagnetic induction panel may be omitted depending on the implementation method of the pen input device. For example, in embodiments where the pen input device uses power from a battery included therein to generate a signal, the electromagnetic induction panel may be omitted.

[0119] According to various embodiments, the multiple layers, stacking structures, or their stacking order included in the display panel 610 or the lower panel 630 may be different. According to various embodiments, the flexible display 130 may be implemented by omitting some components or adding others, depending on its form of provision or convergence tendency.

[0120] According to an embodiment, the support sheet 370 can be attached to the lower panel 630 along the first portion ① of the flexible display 130. Various polymer adhesive members (not shown) can be provided between the support sheet 370 and the lower panel 630. When the flexible display 130 is disposed in the sliding plate 120, the folded portion ④ of the second portion ② can be bent with a corresponding radius of curvature R, and the joining portion ⑤ of the second portion ② can be located between the first portion ① and the sliding plate 120. Therefore, a portion of the support sheet 370 can be located between the joining portion ⑤ of the first portion ① and the second portion ②.

[0121] Figure 8 This is a plan view showing the support sheet 370 in its unfolded state according to an embodiment.

[0122] Reference Figure 6A , Figure 7 and Figure 8 In an embodiment, the support sheet 370 may include a first portion 371 disposed along a first portion ① of the flexible display 130, and a flexible portion ③ extending from the first portion 371 and along the flexible display 130 (see Figure 3 , Figure 4 , Figure 5 or Figure 6A The second part 372 is provided. The first part 371 may include a first flat portion 810 provided along the flat portion 130a and a first curved portion 820 provided along the first curved portion 130b. The first curved portion 820 may include a grid structure 802 having a plurality of openings (or a plurality of slits) 801. For example, the plurality of openings 801 may be formed periodically, may have substantially the same shape, and may be arranged repeatedly at regular intervals. The display assembly 700 may be provided and supported on Figure 3 , Figure 4 or Figure 5 At the sliding plate 120; therefore, a screen can be formed (e.g., Figure 1A or Figure 2A The display assembly 700 has a flat portion 130a and a first curved portion 130b. According to an embodiment, the curved portion 790 of the display assembly 700 can be bent along and disposed at the curved portion 121 of the sliding plate 120; thus, the first curved portion 130b of the screen can be formed. The support piece 370 provides elasticity (or elastic restoring force) to return the curved portion 790 to its unfolded state, but because of the grid structure 802, the first curved portion 820 can be more flexible than the first flat portion 810 and can contribute to the flexibility of the curved portion 790. When the flexibility of the curved portion 790 is ensured, the curved portion 790 can be easily attached to the curved portion 121 of the sliding plate 120. According to various embodiments (not shown), the grid structure 802 of the first curved portion 820 is not limited to... Figure 8The embodiments described are as follows, and can be implemented in various other forms. According to various embodiments, the support sheet 370 may include recessed patterns (not shown) comprising a plurality of recesses replacing a grid structure, and the recessed patterns may contribute to the flexibility of the flexible display 130. According to various embodiments, the grid structure or recessed pattern may extend to and be disposed within at least a portion of the flat portion 130a of the screen. According to various embodiments, the support sheet 370 including the grid structure or recessed pattern may be formed in multiple layers.

[0123] According to an embodiment, the second portion 372 of the support sheet 370 may be configured opposite to the first curved portion 820, and the first flat portion 810 may be located between the second portion 372 and the first curved portion 820. The second portion 372 may include a grid structure comprising a plurality of openings (or a plurality of slits). The support sheet 370 may provide elasticity (or elastic restoring force) to allow the flexible portion ③ of the flexible display 130 (see...) Figure 3 , Figure 4 , Figure 5 or Figure 6A The second portion 372 is restored to its unfolded state, but due to the grid structure, it can be more flexible than the first flat portion 810 of the first portion 371 and can contribute to the flexibility of the bendable portion ③. According to various embodiments, a plurality of recessed patterns can be provided as an alternative to the grid structure.

[0124] According to an embodiment, the grid structure of the second portion 372 may be implemented in a shape substantially the same as that of the grid structure 802 included in the first curved portion 820 of the first portion 371. According to some embodiments, the grid structure 802 included in the first curved portion 820 of the first portion 371 may be implemented in a form that is at least partially different from the grid structure of the second portion 372.

[0125] According to various embodiments, the shape (e.g., width) or the arrangement spacing of the plurality of openings 801 included in the grid structure 802 of the first curved portion 820 may be implemented differently depending on the curvature or radius of curvature of the first curved portion 820. According to various embodiments, the shape or the arrangement spacing of the plurality of openings included in the grid structure of the second portion 372 may be implemented differently depending on the curvature or radius of curvature of the second portion 372.

[0126] According to an embodiment, when the folded portion ④ included in the second part ② is bent, its radius of curvature R can be a value capable of reducing the stress generated in the folded portion ④ due to bending. The folded portion ④ can be bent, for example, with a minimum radius of curvature R, while preventing damage to the folded portion ④ by reducing the stress that may occur due to bending. A minimum radius of curvature R can contribute to the thinning of the display assembly 700 (e.g., minimizing the spacing between the joint portion ⑤ of the first part ① and the second part ②).

[0127] According to an embodiment, the spacer 740 may be at least partially located between the support sheet 370 and the joint portion ⑤ of the second portion ②. The spacer 740 may be disposed in the space (not shown) between the support sheet 370 and the second portion 622 of the base film 620 to reduce the stress on the folded portion ④, while allowing the folded portion ④ to be arranged in a bent state with a corresponding radius of curvature R. The spacer 740 may comprise, for example, a non-metallic material (e.g., a polymer) and / or a metallic material.

[0128] The display panel 610 and / or the lower panel 630 may have a thickness of, for example, about 30 μm. According to an embodiment, in order to minimize stress generated in the portion of the extension 614 of the display panel 610 located in the folded portion ④, the radius of curvature R of the folded portion ④ may be about 300 μm, and the gap D between the display panel 610 and the portion of the extension 614 located in the joining portion ⑤ may be about 600 μm. The first portion 621 and / or the second portion 622 of the base film 620 may have a thickness of about 50 μm. The support sheet 370, the spacer 740, and / or the lower panel 630 may be formed with a thickness capable of maintaining the gap D.

[0129] According to some embodiments (not shown), the second portion 622 of the support sheet 370 and the base film 620 can be bonded to each other by a polymer adhesive member (not shown) without the spacer 740. In this case, the adhesive member can be formed with a thickness that reduces the stress on the folded portion ④ while allowing the folded portion ④ of the second portion ② to bend with a corresponding radius of curvature R.

[0130] Refer to Figure 6. Figure 7 and Figure 8In an embodiment, the spacer 740 may include: a second flat portion 830, located between the support sheet 370 and a second portion 622 of the base film 620 corresponding to the flat portion 130a of the screen; and a second curved portion 840, disposed along the first curved portion 130b of the screen. The second curved portion 840 may extend along the first curved portion 820 of the support sheet 370. The second curved portion 840 may include a plurality of openings 803. The grid structure of the second curved portion 840 may be formed, for example, at least partially similar to or identical to the grid structure of the first curved portion 820. The spacer 740 provides elasticity (or elastic restoring force) to restore the curved portion 790 of the display assembly 700 to its unfolded state, but because of the grid structure, the second curved portion 840 may be more flexible than the second flat portion 830 and may contribute to the flexibility of the curved portion 790. When ensuring the flexibility of the curved portion 790, the curved portion 790 can be easily attached to the curved portion 121 of the sliding plate 120.

[0131] When the first curved portion 820 of the support piece 370 is bent and disposed within the curved portion 790, stress may concentrate at the boundary between the first flat portion 810 and the first curved portion 820; therefore, there is a possibility that the support piece 370 may be damaged (e.g., cracked). According to an embodiment, the grid structure of the support piece 370 may further extend to at least a portion of the first flat portion 810 and be disposed within at least a portion of the first flat portion 810. For example, the grid structure of the support piece 370 may further extend to at least a portion of the first flat portion 810 and be disposed within at least a portion of the first flat portion 810, such as in an opening indicated by reference numeral 801a.

[0132] When the second curved portion 840 of the spacer 740 is bent and disposed within the curved portion 790, stress may concentrate in the boundary portion between the second flat portion 830 and the second curved portion 840; therefore, there is a possibility that the spacer 740 may be damaged (e.g., cracked). According to an embodiment, the grid structure of the spacer 740 may further extend to at least a portion of the second flat portion 830. For example, the grid structure of the spacer 740 may further extend to at least a portion of the second flat portion 830 and be disposed within at least a portion of the second flat portion 830, such as in an opening indicated by reference numeral 803a.

[0133] According to various embodiments, the plurality of openings 801 included in the first curved portion 820 of the support piece 370 and the plurality of openings 803 included in the second curved portion 840 of the spacer 740 may be configured to at least partially overlap. This may contribute to the flexibility of the curved portion 790.

[0134] According to an embodiment, the plurality of openings 801 included in the first curved portion 820 may have a first width W1 extending along a curve (not shown) of the first curved portion 130b (see...). Figure 7 and Figure 8 The second curved portion 840 may be closer to the inside than the first curved portion 820, and the plurality of openings 803 included in the second curved portion 840 may have a second width W2 extending along the curvature line of the first curved portion 130b of the screen. According to an embodiment, the second width W2 may be greater than the first width W1, which may contribute to the flexibility of the curved portion 790.

[0137] According to an embodiment, the spacer 740 may include a polymer film 930, a first adhesive member 910, and / or a second adhesive member 920. The polymer film 930 may be, for example, a polyester (PET) film. The first adhesive member 910 may be disposed between the polymer film 930 and the support sheet 370. The second adhesive member 920 may be disposed between the polymer film 930 and a second portion 622 of the base film 620. The first adhesive member 910 and / or the second adhesive member 920 may include adhesive materials of various polymers. The spacer 740 may be disposed in the space S1 between the support sheet 370 and the second portion 622 of the base film 620 so that the folded portion ④ can be arranged in a bent state with a corresponding radius of curvature R, thereby reducing the stress on the folded portion ④.

[0138] According to various embodiments, the polymer film 930 may include materials for heat dissipation or reinforcement of the display assembly 900.

[0139] According to various embodiments, a film made of a metallic material may be provided instead of the polymer film 930. For example, the film replacing the polymer film 930 may include a metallic material, such as copper or a copper alloy, for heat dissipation and / or reinforcement. For example, the metallic film replacing the polymer film 930 may include stainless steel for reinforcement. According to various embodiments, the metallic film replacing the polymer film 930 may contribute to electromagnetic interference (EMI) shielding for the display assembly 900.

[0140] According to various embodiments, multiple membranes (not shown) comprising non-metallic and / or metallic materials may be provided instead of polymer membrane 930.

[0141] According to embodiments, the first adhesive member 910 and the second adhesive member 920 may have different thicknesses. According to some embodiments, the first adhesive member 910 and the second adhesive member 920 may have substantially the same thickness.

[0142] According to embodiments, the first adhesive member 910 may be an adhesive member having a different composition from that of the second adhesive member 920.

The third film 1050 may be located between the second adhesive member 1020 and the first film 1030. According to various embodiments, adhesive members may be provided between the first film 1030 and the second film 1040 and / or between the second film 1040 and the third film 1050.

[0146] According to embodiments, the first film 1030, the second film 1040, and / or the third film 1050 may comprise non-metallic and / or metallic materials for heat dissipation and / or reinforcement of the display assembly 900.

[0148] According to various embodiments, Figure 11 The support sheet 1100 in the embodiment can be replaced Figure 7 The support plate 370 is set in Figure 7 In the display component 700.

[0149] Reference Figure 11 In an embodiment, the support sheet 1100 may include a support along... Figure 7 The first curved portion 130b is provided with a first curved portion 1120. The support piece 1100 may include a surface 1101 and another surface 1102 positioned opposite to each other. According to an embodiment, the support piece 1100 may include a recessed pattern 1104, which includes a plurality of recesses (or grooves) 1103 formed in a surface 1101 in the first curved portion 1120. The recessed pattern 1104 may extend along... Figure 7 The curve of the first curved portion 130b is set. The support piece 1100 can provide elasticity (or elastic restoring force) to hold Figure 7The curved portion 790 returns to its unfolded state, and the first curved portion 1120, which includes the recessed pattern 1104, can contribute to the flexibility of the curved portion 790.

[0150] According to an embodiment, a surface 1101 including the recessed pattern 1104 may face Figure 7 The lower panel 630, the other surface 1102 can face Figure 7 The spacer 740. According to another embodiment, a surface 1101 including the recessed pattern 1104 may face... Figure 7 The spacer 740, the other surface 1102 can face Figure 7 The lower panel is 630.

[0151] According to various embodiments, the shape (e.g., width or depth) or the arrangement spacing of the plurality of recesses 1103 included in the recessed pattern 1104 may be implemented differently depending on the curvature of the first curved portion 1120.

[0152] According to various embodiments, a recessed pattern may be formed on another surface 1102 of the support sheet 1100.

[0153] According to various embodiments, the recessed pattern 1104 may extend to the flat portion 130a of the screen (see...). Figure 7 At least a portion of the flat portion 130a of the screen is disposed in at least a portion of the flat portion 130a of the screen.

[0154] Figure 12 This is a cross-sectional view 1200 showing a first support piece 1210 and a second support piece 1220 according to various embodiments.

[0155] Reference Figure 12 In this embodiment, the first support piece 1210 can be coupled with... Figure 7 The support sheet 370 is substantially the same. For example, the first support sheet 1210 may include: a first portion 1201 (e.g., Figure 8 Part 1 (371), along Figure 7 The first portion ① of the flexible display 130 shown is configured; and the second portion 1202 (e.g., Figure 8 The second part 372), extends from the first part 1201 and along the flexible portion ③ of the flexible display 130 (see Figure 3 , Figure 4 , Figure 5 Or as shown in Figure 6). The first portion 1201 may include: a first flat portion 1231 (e.g., Figure 8 The first flat section 810), along Figure 7 The flat portion 130a is provided; and the first curved portion 1232 (e.g., Figure 8 The first curved section 820), along Figure 7The first curved portion 130b is provided. The first curved portion 1232 and the second portion 1202 may include a grid structure with multiple openings (e.g., Figure 8 (802) lattice structure.

[0156] According to an embodiment, the second support piece 1220 may be disposed at least partially along the first support piece 1210. Figure 12 The first support piece 1210 and the second support piece 1220 of the embodiment can be replaced Figure 7 The support plate 370 is set in Figure 7 In the display assembly 700. For example, the second support piece 1220 may be configured to... Figure 7 The lower panel 630 is spaced apart, and the first support piece 1210 is located between the second support piece 1220 and the lower panel 630. Alternatively, the first support piece 1210 can be configured to be... Figure 7 The lower panel 630 is spaced apart, and the second support piece 1220 is located between the first support piece 1210 and the lower panel 630.

[0157] According to an embodiment, the second support piece 1220 can reinforce the first support piece 1210. For example, when tension is applied to the first support piece 1210, the first flat portion 1231 of the first support piece 1210 does not extend, but due to the grid structure, the second portion 1202 and / or the first curved portion 1232 of the first support piece 1210 can elongate. The second support piece 1220 can prevent the second portion 1202 and / or the first curved portion 1232 of the first support piece 1210 from elongating. The second support piece 1220 may have the ability to reinforce the first support piece 1210 while minimizing elasticity (or elastic restoring force) to... Figure 7 The thickness of the bent portion 790 returns to its unfolded state. The second support piece 1220 may have a thickness that allows it to recover without reducing... Figure 7 The thickness of the first support sheet 1210 is increased to enhance the flexibility of the curved portion 790. According to an embodiment, the second thickness T2 of the second support sheet 1220 may be less than the first thickness T1 of the first support sheet 1210.

[0158] According to embodiments, the thickness of the second support piece 1220 may be substantially constant. According to some embodiments, the thickness of the second support piece 1220 may be partially different. For example, a portion of the second support piece 1220 may be configured to correspond to a second portion 1202 and / or a first curved portion 1232 of the first support piece 1210 of the grid structure, and may have a relatively thin thickness. According to various embodiments, the second support piece 1220 may be configured to correspond to a portion of the first support piece 1210 (e.g., at least a portion of the first portion 1201 or the second portion 1202).

[0159] According to an embodiment, the first support sheet 1210 and / or the second support sheet 1220 may comprise metallic and / or non-metallic materials. For example, the first support sheet 1210 and / or the second support sheet 1220 may comprise stainless steel. Alternatively, the first support sheet 1210 and / or the second support sheet 1220 may comprise engineering plastics.

[0160] According to various embodiments, the second support sheet 1220 can be used to diffuse, disperse, or radiate heat. Compared to the first flat portion 1231 of the first support sheet 1210, the second portion 1202 and / or the first curved portion 1232 of the first support sheet 1210 may have difficulty diffusing, dispersing, or dissipating heat due to the grid structure including multiple openings. The second support sheet 1220 can supplement the thermal conductivity of the first support sheet 1210.

[0161] Figure 13 This is a cross-sectional view showing a portion of a display assembly 1300 according to another embodiment.

[0162] Reference Figure 13 In this embodiment, the display assembly 1300 may include a display panel 610, a base film 620, a lower panel 630, a display driving circuit 640, an FPCB 137, a transparent cover 710, an optically transparent adhesive member 720, an optical layer 730, a support sheet 1370, and / or a spacer 1340. The base film 620 may include a first portion 621 located in a first portion ① of the flexible display 130 and a second portion 622 located in a second portion ② of the flexible display 130. (The remaining text is omitted.) Figure 13 Redundant descriptions of some of the figure labels.

[0163] According to an embodiment, the curved portion 790 of the display assembly 1300 may have an irregular radius of curvature along a curve (see reference numeral 1303) of the first curved portion 130b. For example, the radius of curvature of the curved portion 790 may decrease as the distance from the flat portion 130a increases. According to an embodiment, the support piece 1370 may include an opening pattern (or grid structure) having a plurality of openings formed in the curved portion 790, and the width W4 of the plurality of openings extending along the curve 1303 of the first curved portion 130b may be substantially constant. According to an embodiment, the support piece 1370 may include portions between the plurality of openings, and the width of the portions extending along the curve 1303 may decrease as the distance from the flat portion 130a increases. For example, in the opening pattern of the support piece 1370, a first portion spaced a first distance from the flat portion 130a along the curve 1303 may correspond to a first radius of curvature of the curved portion 790 and may extend along the curve 1303 to have a first width W5. In the opening pattern of the support piece 1370, the second portion, which is spaced apart from the flat portion 130a by a second distance (greater than the first distance) along the curve 1303, may correspond to a second radius of curvature (less than the first radius of curvature) and may extend along the curve 1303 to have a second width W6 (less than the first width W5).

[0164] According to some embodiments (not shown), the portion between the plurality of openings included in the opening pattern of the support piece 1370 may be implemented to have substantially the same width along the curve 1303 of the first curved portion 130b.

[0165] According to an embodiment, spacer 1340 may include an opening pattern that at least partially overlaps with the opening pattern of support piece 1370. Therefore, when the curved portion 790 is bent and configured such that the radius of curvature decreases with increasing distance from the flat portion 130a, support piece 1370 and spacer 1340 may contribute to the flexibility that allows the curved portion 790 to bend smoothly. According to an embodiment, spacer 1340 may include an opening pattern formed in a shape substantially similar to or the same as that of support piece 1370. For example, a plurality of openings included in the opening pattern of spacer 1340 may overlap with the same width (e.g., width W41 extending along curve 1303) as the plurality of openings included in the opening pattern of support piece 1370. For example, portions between the plurality of openings included in the opening pattern of spacer 1340 may overlap with the same width (e.g., the same width extending along curve 1303) as the portions between the plurality of openings included in the opening pattern of support piece 1370.

[0166] When the bent portion 790 is bent and disposed relative to the flat portion 130a, stress may concentrate at the boundary portion between the flat portion 130a and the first bent portion 130b; thus, there is a possibility that damage (e.g., breakage) may occur at the position of the support piece 1370 and / or the spacer 1340 corresponding to the boundary portion. According to various embodiments (not shown), the opening pattern of the support piece 1370 or the opening pattern of the spacer 1340 may extend to at least a part of the flat portion 130a of the screen and be disposed in at least a part of the flat portion 130a of the screen, thereby reducing the stress concentrated at the boundary portion.

[0167] According to another embodiment (not shown), the opening pattern of the spacer 1340 may be formed to be at least partially different from the opening pattern of the support piece 1370. For example, the plurality of openings included in the opening pattern of the spacer 1340 and the plurality of openings included in the opening pattern of the support piece 1370 may be aligned with each other, but may extend along the curve 1303 with different widths (e.g., W41>W4 or W41<W4). For example, the portions between the plurality of openings included in the opening pattern of the spacer 1340 and the portions between the plurality of openings included in the opening pattern of the support piece 1370 may be aligned with each other, but may extend along the curve 1303 to have different widths. The opening pattern of the spacer 1340 and the opening pattern of the support piece 1370 may be at least partially implemented as other different shapes.

[0168] According to some embodiments (not shown), at least one of the opening pattern of the support piece 1370 and the opening pattern of the spacer 1340 may be replaced with a recessed pattern including a plurality of recesses (e.g., Figure 11 the recessed pattern 1104). When the opening pattern of the support piece 1370 is replaced with a recessed pattern, the recessed pattern may be formed on one surface of the support piece 1370 facing the lower panel 630 and / or on the other surface of the support piece 1370 facing the spacer 1340. When the opening pattern of the spacer 1340 is replaced with a recessed pattern, the recessed pattern may be formed on one surface of the spacer 1340 facing the second portion 622 of the base film 620 and / or on the other surface of the spacer 1340 facing the support piece 1370.

[0169] According to some embodiments (not shown), the opening pattern of the support piece 1370 or the opening pattern of the spacer 1340 may be omitted.

[0170] Figure 14 is a cross-sectional view showing a part of the display assembly 1400 according to another embodiment.

[0171] Refer to Figure 14In this embodiment, the display assembly 1400 may include a display panel 610, a base film 620, a lower panel 630, a display driving circuit 640, an FPCB 137, a transparent cover 710, an optically transparent adhesive member 720, an optical layer 730, a support sheet 1470, and / or a spacer 1440. The base film 620 may include a first portion 621 located in a first portion ① of the flexible display 130 and a second portion 622 located in a second portion ② of the flexible display 130. (The remaining text is omitted.) Figure 14 Redundant descriptions of some of the figure labels.

[0172] According to an embodiment, the radius of curvature of the curved portion 790 may decrease as the distance from the flat portion 130a increases. According to an embodiment, the support piece 1470 may include an opening pattern (or grid structure) having a plurality of openings formed in the curved portion 790, and the width of the plurality of openings extending along the curve 1403 of the first curved portion 130b may increase as the distance from the flat portion 130a increases. For example, in the opening pattern of the support piece 1470, a first opening spaced a first distance from the flat portion 130a along the curve 1403 may correspond to a first radius of curvature of the curved portion 790 and may extend along the curve 1403 to have a first width W7. In the opening pattern of the support piece 1470, a second opening spaced a second distance (greater than the first distance) from the flat portion 130a along the curve 1403 may correspond to a second radius of curvature (less than the first radius of curvature) and may extend along the curve 1403 to have a second width W8 (greater than the first width W7). According to an embodiment, the support piece 1470 may include a portion between a plurality of openings, and the width W9 of the portion extending along curve 1403 may be substantially constant.

[0173] According to an embodiment, spacer 1440 may include an opening pattern that at least partially overlaps with the opening pattern of support piece 1470. Therefore, when the curved portion 790 is bent and configured such that the radius of curvature decreases with increasing distance from the flat portion 130a, support piece 1470 and spacer 1440 may contribute to the flexibility that allows the curved portion 790 to bend smoothly. According to an embodiment, spacer 1440 may include an opening pattern formed in a shape substantially similar to or the same as that of support piece 1470. For example, a plurality of openings included in the opening pattern of spacer 1440 may overlap with the same width (e.g., the same width extending along curve 1403) as a plurality of openings included in the opening pattern of support piece 1470. For example, portions between a plurality of openings included in the opening pattern of spacer 1440 may overlap with the same width (e.g., the same width extending along curve 1403) as portions between a plurality of openings included in the opening pattern of support piece 1470.

[0174] When the curved portion 790 is bent and positioned relative to the flat portion 130a, stress may concentrate at the boundary portion between the flat portion 130a and the first curved portion 130b; therefore, there is a possibility that damage (e.g., breakage) may occur at the location corresponding to the boundary portion of the support piece 1470 and / or the spacer 1440. According to various embodiments (not shown), the opening pattern of the support piece 1470 or the opening pattern of the spacer 1440 may extend to at least a portion of the flat portion 130a of the screen and be disposed in at least a portion of the flat portion 130a of the screen, thereby reducing the stress concentrated at the boundary portion.

[0175] According to another embodiment (not shown), the opening pattern of the spacer 1440 may be formed to be at least partially different from the opening pattern of the support piece 1470. For example, the plurality of openings included in the opening pattern of the spacer 1440 and the plurality of openings included in the opening pattern of the support piece 1470 may be aligned with each other, but may extend along the curve 1403 with different widths. For example, portions between the plurality of openings included in the opening pattern of the spacer 1440 and portions between the plurality of openings included in the opening pattern of the support piece 1470 may be aligned with each other, but may extend along the curve 1403 with different widths. The opening patterns of the spacer 1440 and the opening patterns of the support piece 1470 may be at least partially implemented as other different shapes.

[0176] According to some embodiments (not shown), at least one of the opening patterns of the support piece 1470 and the spacer 1440 may be a recessed pattern including a plurality of recesses (e.g., Figure 11 The recessed pattern 1104 is used instead. When the opening pattern of the support piece 1470 is replaced by a recessed pattern, the recessed pattern may be formed on one surface of the support piece 1470 facing the lower panel 630 and / or on the other surface of the support piece 1470 facing the spacer 1440. When the opening pattern of the spacer 1440 is replaced by a recessed pattern, the recessed pattern may be formed on one surface of the spacer 1440 facing the second portion 622 of the base film 620 and / or on the other surface of the spacer 1440 facing the support piece 1470.

[0177] According to some embodiments (not shown), the opening pattern of the support piece 1470 or the opening pattern of the spacer 1440 may be omitted.

[0178] Figure 15 This is a cross-sectional view showing a portion of a display assembly 1500 according to another embodiment.

[0179] Reference Figure 15In this embodiment, the display assembly 1500 may include a display panel 610, a base film 620, a lower panel 630, a display driving circuit 640, an FPCB 137, a transparent cover 710, an optically transparent adhesive member 720, an optical layer 730, a support sheet 1570, and / or a spacer 1540. The base film 620 may include a first portion 621 located in a first portion ① of the flexible display 130 and a second portion 622 located in a second portion ② of the flexible display 130. (The remaining text is omitted.) Figure 15 Redundant descriptions of some of the figure labels.

[0180] According to an embodiment, the radius of curvature of the curved portion 790 may decrease as the distance from the flat portion 130a increases. According to an embodiment, the support piece 1570 may include an opening pattern (or grid structure) having a plurality of openings formed in the curved portion 790, and the width of the plurality of openings extending along the curve 1503 of the first curved portion 130b may decrease as the distance from the flat portion 130a increases. For example, in the opening pattern of the support piece 1570, a first opening spaced a first distance from the flat portion 130a along the curve 1503 may correspond to a first radius of curvature of the curved portion 790 and may extend along the curve 1503 to have a first width W10. In the opening pattern of the support piece 1570, a second opening spaced a second distance (greater than the first distance) from the flat portion 130a along the curve 1503 may correspond to a second radius of curvature (less than the first radius of curvature) and may extend along the curve 1503 to have a second width W11 (less than the first width W10).

[0181] According to an embodiment, the support piece 1570 may include a portion between a plurality of openings, and the width of the portion extending along the curve 1503 may decrease as the distance from the flat portion 130a increases. For example, in the opening pattern of the support piece 1570, a third portion spaced a third distance from the flat portion 130a along the curve 1503 may correspond to a third radius of curvature of the curved portion 790, and may extend along the curve 1503 to have a third width W12. In the opening pattern of the support piece 1570, a fourth portion spaced a fourth distance (greater than the third distance) from the flat portion 130a along the curve 1503 may correspond to a fourth radius of curvature (less than the third radius of curvature), and may extend along the curve 1503 to have a fourth width W13 (less than the third width W12).

[0182] According to an embodiment, the spacer 1540 may include an opening pattern that at least partially overlaps with the opening pattern of the support piece 1570. Therefore, when the curved portion 790 is bent and configured such that the radius of curvature decreases with increasing distance from the flat portion 130a, the support piece 1570 and the spacer 1540 may contribute to the flexibility that allows the curved portion 790 to bend smoothly. According to an embodiment, the spacer 1540 may include an opening pattern formed in a shape substantially similar to or the same as that of the support piece 1570. For example, a plurality of openings included in the opening pattern of the spacer 1540 may overlap with the same width (e.g., the same width extending along curve 1503) as the plurality of openings included in the opening pattern of the support piece 1570. For example, portions between the plurality of openings included in the opening pattern of the spacer 1540 may overlap with the same width (e.g., the width extending along curve 1503) as the portions between the plurality of openings included in the opening pattern of the support piece 1570.

[0183] When the curved portion 790 is bent and positioned relative to the flat portion 130a, stress may concentrate at the boundary portion between the flat portion 130a and the first curved portion 130b; therefore, there is a possibility that damage (e.g., breakage) may occur to the support piece 1570 and / or the spacer 1540 at the location corresponding to the boundary portion. According to various embodiments (not shown), the opening pattern of the support piece 1570 or the opening pattern of the spacer 1540 may extend to at least a portion of the flat portion 130a of the screen and be disposed in at least a portion of the flat portion 130a of the screen, thereby reducing the stress concentrated at the boundary portion.

[0184] According to another embodiment (not shown), the opening pattern of the spacer 1540 may be formed to be at least partially different from the opening pattern of the support piece 1570. For example, the plurality of openings included in the opening pattern of the spacer 1540 and the plurality of openings included in the opening pattern of the support piece 1570 may be aligned with each other, but may extend along the curve 1503 with different widths. For example, portions between the plurality of openings included in the opening pattern of the spacer 1540 and portions between the plurality of openings included in the opening pattern of the support piece 1570 may be aligned with each other, but may extend along the curve 1503 with different widths. The opening patterns of the spacer 1540 and the opening patterns of the support piece 1570 may be at least partially implemented as other different shapes.

[0185] According to some embodiments (not shown), at least one of the opening patterns of the support piece 1570 and the spacer 1540 may be a recessed pattern comprising a plurality of recesses (e.g., Figure 11The recessed pattern 1104 is used instead. When the opening pattern of the support piece 1570 is replaced by a recessed pattern, the recessed pattern can be formed on one surface of the support piece 1570 facing the lower panel 630 and / or on the other surface of the support piece 1570 facing the spacer 1540. When the opening pattern of the spacer 1540 is replaced by a recessed pattern, the recessed pattern can be formed on one surface of the spacer 1540 facing the second portion 622 of the base film 620 and / or on the other surface of the spacer 1540 facing the support piece 1570.

[0186] According to some embodiments (not shown), the opening pattern of the support piece 1570 or the opening pattern of the spacer 1540 may be omitted.

The base film 620 may include a first portion 621 located in a first portion ① of the flexible display 130 and a second portion 622 located in a second portion ② of the flexible display 130.

[0189] According to an embodiment, the radius of curvature of the curved portion 790 may decrease as the distance from the flat portion 130a increases. According to an embodiment, the support piece 1670 may include an opening pattern (or grid structure) having a plurality of openings formed in the curved portion 790, and the width of the plurality of openings extending along the curve 1603 of the first curved portion 130b may increase as the distance from the flat portion 130a increases. For example, in the opening pattern of the support piece 1670, a first opening spaced a first distance from the flat portion 130a along the curve 1603 may correspond to a first radius of curvature of the curved portion 790 and may extend along the curve 1603 to have a first width W14. In the opening pattern of the support piece 1670, a second opening spaced a second distance (greater than the first distance) from the flat portion 130a along the curve 1603 may correspond to a second radius of curvature (less than the first radius of curvature) and may extend along the curve 1603 to have a second width W15 (greater than the first width W14).

[0190] According to an embodiment, the support piece 1670 may include a portion between a plurality of openings, and the width of the portion extending along curve 1603 may decrease as the distance from the flat portion 130a increases. For example, in the opening pattern of the support piece 1670, a third portion spaced a third distance from the flat portion 130a along curve 1603 may correspond to a third radius of curvature of the curved portion 790, and may extend along curve 1603 to have a third width W16. In the opening pattern of the support piece 1670, a fourth portion spaced a fourth distance (greater than the third distance) from the flat portion 130a along curve 1603 may correspond to a fourth radius of curvature (less than the third radius of curvature), and may extend along curve 1603 to have a fourth width W17 (less than the third width W16).

[0191] According to an embodiment, spacer 1640 may include an opening pattern that at least partially overlaps with the opening pattern of support piece 1670. Therefore, when the curved portion 790 is bent and configured such that the radius of curvature decreases with increasing distance from the flat portion 130a, support piece 1670 and spacer 1640 may contribute to the flexibility that allows the curved portion 790 to bend smoothly. According to an embodiment, spacer 1640 may include an opening pattern formed in a shape substantially similar to or the same as that of support piece 1670. For example, a plurality of openings included in the opening pattern of spacer 1640 may overlap with the same width (e.g., the same width extending along curve 1603) as a plurality of openings included in the opening pattern of support piece 1670. For example, portions between a plurality of openings included in the opening pattern of spacer 1640 may overlap with the same width (e.g., the width extending along curve 1603) as a portion between a plurality of openings included in the opening pattern of support piece 1670.

[0192] According to various embodiments (not shown), the opening pattern of the support piece 1670 and / or the plurality of openings and / or the portions between the plurality of openings included in the spacer 1640 are not limited to those shown, and may be formed in different shapes according to various embodiments. For example, the width of the plurality of openings extending along the curve 1603 of the first curved portion 130b may decrease as the distance from the flat portion 130a increases, and the width of the portions between the plurality of openings extending along the curve 1603 may be substantially constant. As another example, the width of the plurality of openings extending along the curve 1603 of the first curved portion 130b may decrease as the distance from the flat portion 130a increases, and the width of the portions between the plurality of openings extending along the curve 1603 may increase as the distance from the flat portion 130a increases.

[0193] When the curved portion 790 is bent and positioned relative to the flat portion 130a, stress may concentrate at the boundary portion between the flat portion 130a and the first curved portion 130b; therefore, there is a possibility that damage (e.g., breakage) may occur at the location of the support piece 1670 and / or the spacer 1640 corresponding to the boundary portion. According to various embodiments (not shown), the opening pattern of the support piece 1670 or the opening pattern of the spacer 1640 may extend to at least a portion of the flat portion 130a of the screen and be disposed in at least a portion of the flat portion 130a of the screen, thereby reducing the stress concentrated at the boundary portion.

[0194] According to another embodiment (not shown), the opening pattern of the spacer 1640 may be formed to be at least partially different from the opening pattern of the support piece 1670. For example, the plurality of openings included in the opening pattern of the spacer 1640 and the plurality of openings included in the opening pattern of the support piece 1670 may be aligned with each other, but may extend along curve 1603 to have different widths. For example, portions between the plurality of openings included in the opening pattern of the spacer 1640 and the portions between the plurality of openings included in the opening pattern of the support piece 1670 may be aligned with each other, but may extend along curve 1603 to have different widths. The opening patterns of the spacer 1640 and the opening patterns of the support piece 1670 may be at least partially implemented as other different shapes.

[0195] According to some embodiments (not shown), at least one of the opening patterns of the support piece 1670 and the spacer 1640 may be a recessed pattern comprising a plurality of recesses (e.g., Figure 11 The recessed pattern 1104 is used instead. When the opening pattern of the support piece 1670 is replaced by a recessed pattern, the recessed pattern may be formed on one surface of the support piece 1670 facing the lower panel 630 and / or on the other surface of the support piece 1670 facing the spacer 1640. When the opening pattern of the spacer 1640 is replaced by a recessed pattern, the recessed pattern may be formed on one surface of the spacer 1640 facing the second portion 622 of the base film 620 and / or on the other surface of the spacer 1640 facing the support piece 1670.

[0196] According to some embodiments (not shown), the opening pattern of the support piece 1670 or the opening pattern of the spacer 1640 may be omitted.

The front cover 1711 may include a flat region 1725 between the first region 1721, the second region 1722, the third region 1723, and the fourth region 1724.

According to an embodiment, electronic device 1801 can communicate with electronic device 1804 via server 1808. According to an embodiment, electronic device 1801 may include a processor 1820, a memory 1830, an input module 1850, a sound output module 1855, a display module 1860, an audio module 1870, a sensor module 1876, an interface 1877, a connection terminal 1878, a haptic module 1879, a camera module 1880, a power management module 1888, a battery 1889, a communication module 1890, a Subscriber Identity Module (SIM) 1896, or an antenna module 1897. In some embodiments, at least one of the aforementioned components (e.g., connection terminal 1878) may be omitted from electronic device 1801, or one or more other components may be added to electronic device 1801. In some embodiments, some of the aforementioned components (e.g., sensor module 1876, camera module 1880, or antenna module 1897) may be implemented as a single integrated component (e.g., display module 1860).

[0204] Processor 1820 may run software (e.g., program 1840) to control at least one other component (e.g., hardware or software component) of electronic device 1801 connected to processor 1820, and may perform various data processing or calculations.

For example, when electronic device 1801 includes a main processor 1821 and an auxiliary processor 1823, the auxiliary processor 1823 may be adapted to consume less power than the main processor 1821, or may be adapted to be dedicated to a specific function. The auxiliary processor 1823 may be implemented separately from the main processor 1821, or may be implemented as part of the main processor 1821.

[0205] When the main processor 1821 is inactive (e.g., in sleep) state, the auxiliary processor 1823 (other than the main processor 1821) can control at least some of the functions or states associated with at least one component of the electronic device 1801 (e.g., display module 1860, sensor module 1876, or communication module 1890), or when the main processor 1821 is active (e.g., running an application), the auxiliary processor 1823 can work with the main processor 1821 to control at least some of the functions or states associated with at least one component of the electronic device 1801 (e.g., display module 1860, sensor module 1876, or communication module 1890).

[0219] Communication module 1890 can support the establishment of a direct (e.g., wired) or wireless communication channel between electronic device 1801 and external electronic devices (e.g., electronic device 1802, electronic device 1804, or server 1808), and perform communication via the established communication channel. Communication module 1890 may include one or more communication processors capable of operating independently of processor 1820 (e.g., application processor (AP)) and support direct (e.g., wired) or wireless communication. According to embodiments, communication module 1890 may include wireless communication module 1892 (e.g., cellular communication module, short-range wireless communication module, or Global Navigation Satellite System (GNSS) communication module) or wired communication module 1894 (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 1898 (e.g., a short-range communication network such as Bluetooth, Wi-Fi Direct, or Infrared Data Association (IrDA)) or a second network 1899 (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 1892 can identify and verify the electronic device 1801 in the communication network (such as the first network 1898 or the second network 1899) using user information (e.g., the International Mobile Subscriber Identity (IMSI)) stored in the user identification module 1896.

[0220] Wireless communication module 1892 can support 5G networks following 4G networks and next-generation communication technologies (such as new radio (NR) access technologies). NR access technologies can support enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), or ultra-reliable low-latency communication (URLLC).

[0223] At least some of the aforementioned components can be interconnected and communicate signals (e.g., commands or data) between them via an inter-peripheral communication scheme (e.g., bus, general purpose input / output (GPIO), serial peripheral interface (SPI), or mobile industrial processor interface (MIPI)).

[0224] According to an embodiment, commands or data can be sent or received between electronic device 1801 and external electronic device 1804 via server 1808 connected to a second network 1899. Each of electronic device 1802 or electronic device 1804 can be a device of the same type as electronic device 1801, or a device of a different type. According to an embodiment, all or some operations that would be performed on electronic device 1801 can be performed on one or more of external electronic devices 1802, external electronic devices 1804, or server 1808. For example, if electronic device 1801 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 1801 may request the one or more external electronic devices to perform at least a portion of the function or service instead of running the function or service, or electronic device 1801 may request the one or more external electronic devices to perform at least a portion of the function or service in addition to running the function or service. Upon receiving the request, 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 1801. Electronic device 1801 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.
