[0040] Reference Figure 1a , Figure 1b , Figure 2a and Figure 2b In one embodiment, the electronic device 100 may be implemented to extend the screen in a sliding manner. Figure 1a and Figure 1b The electronic device 100 is shown in its unextended screen state, and Figure 2a and Figure 2bAn electronic device 100 is shown in an extended screen state. The non-extended screen state is the state where the slider 120 for sliding movement of the display 130 is not slid out, and may be referred to hereinafter as the "closed state." The extended screen state is the maximum extended state where the screen is no longer extended due to the sliding of the slider 120, and may be referred to hereinafter as the "open state." According to various embodiments, the open state may be defined as the state in which the screen is extended compared to the closed state, and the screen may be set in various sizes depending on the movement position of the slider 120. The screen is the effective area of ​​the flexible display 130 that is visually exposed to output images, and the electronic device 100 is capable of adjusting the effective area according to the movement of the slider 120 or the movement of the flexible display 130. In the following description, the open state may refer to the state in which the screen is extended to its maximum extent. In some embodiments, it is arranged to be in Figure 1a The flexible display 130 in the electronic device 100 that can slide to provide a screen may be referred to as a "slide-out display" or "expandable display".

[0041] According to an embodiment, the electronic device 100 may include a sliding structure based on an elastic structure connected to (or associated with) the flexible display 130. When the flexible display 130 is moved a set distance by an external force, the flexible display 130 may switch from a closed state to an open state or from an open state to a closed state without any further external force due to the elastic structure (e.g., semi-automatic sliding operation).

[0042] According to some embodiments, when a signal is generated via 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 due to a driving device (such as a motor connected to the flexible display 130). For example, when a signal is generated via a hardware button or a 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.

[0043] 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 held or grasped by hand, a squeezing gesture of a part of the hand (e.g., palm or fingers) pressing a portion of a predetermined section of the electronic device 100 can be detected by a gesture sensor, and in response to this, the electronic device 100 can switch from a closed state to an open state or from an open state to a closed state.

[0044] According to an embodiment, the flexible display 130 may include a first bendable segment 133 (see [link]). Figure 2aWhen the electronic device 100 switches from a closed state to an open state, the first flexible section 133 provides an extension of the screen. When the electronic device 100 switches from a closed state to an open state, the first flexible section 133 is slidably pulled out from the internal space of the electronic device 100, thus extending the screen. When the electronic device 100 switches from an open state to a closed state, the first flexible section 133 is slidably introduced into the internal space of the electronic device 100, thus retracting the screen. When the electronic device 100 switches from an open state to a closed state, the first flexible section 133 can be bent and moved into the internal space of the electronic device 100. The flexible display 130 can be implemented using a flexible display based on a flexible substrate (e.g., a plastic substrate), and may be referred to hereinafter as a flexible display, wherein the flexible substrate (e.g., a plastic substrate) is formed of a polymer material including polyimide (PI) or polyester fiber (PET (polyester)).

[0045] According to an embodiment, the electronic device 100 may include a housing 110, a sliding plate 120, or a flexible display 130.

For example, the first curved portion 130b and the second curved portion 130c may be substantially symmetrical to each other, wherein the flat portion 130a is located between the first curved portion 130b and the second curved portion 130c. Figure 1a In the closed state, the first bent portion 130b and the second bent portion 130c can be positioned correspondingly with the bent portions 112b and 112c of the rear cover 112, respectively, 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, the first flexible segment 133 in... Figure 1a The portion of the area forming the first curved portion 130b in the closed state can be included when the electronic device 100 is in the closed state.

[0069] According to an embodiment, the flexible display 130 may include a first segment 131 extending from a first bendable segment 133. The first segment 131 may be arranged on a sliding plate 120. When the electronic device 100 is... Figure 1a Switching to the closed state Figure 2a When the screen is in the open state, due to the movement of the sliding plate 120, the first flexible section 133 connected to the first section 131 slides out of the electronic device 100, allowing the screen to expand. When the electronic device 100 switches from the closed state to the open state, due to the movement of the sliding plate 120, at least a portion of the first flexible section 133 is introduced into the electronic device 100, allowing the screen to retract. The support member assembly 300 may include an opening (not shown) for introducing or pulling out the first flexible section 133, and a first pulley 360 may be located in the opening. The opening may include a gap on one side between the first support member 310 and the third support member 330, and the portion 331 of the third support member 330 positioned adjacent to the opening may have a curved shape corresponding to the curved surface of the roller 361.

[0070] According to an embodiment, the support sheet 370 may be attached to the rear surface of the flexible display 130. The rear surface of the flexible display 130 may refer to a surface positioned relative to a light-emitting surface, wherein the light originates from a light-emitting layer (or display panel) comprising a plurality of pixels. For example, the support sheet 370 may include a second segment (not shown), a second flexible segment (not shown), or a third segment (not shown), wherein the second segment is arranged at least partially along the first segment 131, the second flexible segment is arranged along the first flexible segment 133, and the third segment is spaced apart from the second segment and does not overlap with the flexible display 130 if the second flexible segment is located between the second segment and the third segment. According to some embodiments, at least a portion of the second segment or at least a portion of the third segment may be omitted. The support sheet 370 may contribute to the durability of the flexible display 130. The support sheet 370 may reduce the impact of light emitted by the flexible display 130. Figure 1a The closed state and Figure 2aThe loads or stresses that may occur during the switching between open and closed states affect the flexible display 130. When the sliding plate 120 moves, the support sheet 370 prevents the flexible display 130 from being damaged by forces transmitted from the sliding plate 120. Although not shown, the flexible display 130 may include a first layer comprising a plurality of pixels and a second layer bonded to the first layer. The first layer may include, for example, a light-emitting layer and various other layers (e.g., optical layers for improving image quality for outdoor visibility of the screen, such as polarizing layers), wherein the light-emitting layer comprises a plurality of pixels implemented with light-emitting elements (such as organic light-emitting diodes (OLEDs) or micro light-emitting diodes (LEDs)). According to various embodiments, when viewed from above the screen (e.g., along the -z-axis direction), the plurality of pixels may not be arranged in a portion of the flexible display 130 that at least partially overlaps with a portion of an electronic component (e.g., a camera module or sensor module) included in the electronic device 100. According to some embodiments, when viewed from above the screen, the portion of the flexible display 130 that at least partially overlaps with at least one electronic component (e.g., a camera module or sensor module) included in the electronic device 100 may include a pixel structure and / or wiring structure different from the pixel structure and / or wiring structure of other regions. For example, the portion of the flexible display 130 that at least partially overlaps with at least one electronic component (e.g., a camera module or sensor module) may have a pixel density different from the pixel density of other regions. For example, even if the portion of the flexible display 130 that at least partially overlaps with at least one electronic component (e.g., a camera module or sensor module) does not include an opening, the portion may be implemented as a substantially transparent region formed by changing the pixel structure and / or wiring structure. The second layer may include various layers for supporting and protecting the first layer (e.g., a buffer member), blocking light, absorbing or blocking electromagnetic waves, or diffusing heat, dissipating heat, or radiating heat. According to an embodiment, at least a portion of the second layer is a conductive member (e.g., a metal plate). This conductive member can help enhance the rigidity of the electronic device 100 and can be used to block ambient noise and dissipate heat from surrounding heat-generating components (e.g., display driving circuitry). According to an embodiment, the conductive member may include at least one of copper (Cu), aluminum (Al), stainless steel (SUS), or CLAD (e.g., a stack of alternating SUS and Al components). A support sheet 370 may cover at least a portion of the second layer of the flexible display 130 and may be attached to the rear surface of the second layer. The support sheet 370 may be formed of various metallic and / or non-metallic materials (e.g., polymers). According to an embodiment, the support sheet 370 may include stainless steel. According to some embodiments, the support sheet 370 may include engineering plastics. According to some embodiments, the support sheet 370 may be integrally implemented with the flexible display 130.

The second surface 382 may be spaced apart from the support plate 370 with the first surface 381 between the second surface 382 and the support plate 370. When the sliding plate 120 moves, the movement and direction of movement of the multi-bar structure 380 may be guided by rollers 361 that rotate in friction with the second surface 382. According to an embodiment, the second surface 382 may include a plurality of bars (not shown) arranged in a direction (e.g., +y axis direction) extending from a second axis of rotation 363 of the first pulley 360 to a first axis of rotation (not shown). The multi-bar structure 380 may be bent at portions with relatively small thicknesses between the bars. In various embodiments, the multi-bar structure 380 may be referred to by various other terms, such as "flexible guide" or "hinge track." According to various embodiments, various other types of flexible members that perform substantially the same function as the multi-bar structure 380 may replace the multi-bar structure 380.

[0072] According to an embodiment, in Figure 1a The closed state or Figure 2a In the open state, at least a portion of the multi-bar structure 380 can be located on the screen side to support the first flexible segment 133 of the flexible display 130, such that the first flexible segment 133 can be smoothly connected to the first segment 131 of the flexible display 130 without being raised. The multi-bar structure 380 can help enable the first flexible segment 133 to... Figure 1a The closed state and Figure 2a During the switching between open and closed states, the device moves while remaining smoothly connected to the first segment 131 without being raised.

[0073] According to an embodiment, the support sheet 370 can substantially prevent components located inside the electronic device 100 (e.g., the multi-bar structure 380) from being visible through the flexible display 130.

[0074] According to an embodiment, a first belt 410 interconnects a sliding plate 120 with a support plate 370, and a second pulley 440 may be located on the first support member 310 to correspond to the first belt 410. The second pulley 440 may include a rotation axis (not shown) parallel to the rotation axis of the first pulley 360 and may be positioned spaced apart from the first pulley 360. The first support member 310 may include an opening (not shown) through a surface facing the sliding plate 120 and another surface facing the second support member 320, and the second pulley 440 may be arranged in the opening. The first belt 410 may be arranged through the opening, wherein one end 411 of the first belt 410 may be connected to the sliding plate 120, and the other end 412 may be connected to the support plate 370. The second pulley 440 connected to the first belt 410 may guide the movement and direction of movement of the first belt 410. Correspondingly positioned second belts 420 and third pulleys 450 interconnect the sliding plate 120 and support plate 370 at different locations, and can be implemented in substantially the same manner as the correspondingly positioned first belt 410 and second pulleys 440. The third pulley 450, connected to the second belt 420, guides the movement and direction of movement of the second belt 420. Correspondingly positioned third belts 430 and fourth pulleys 460 interconnect the sliding plate 120 and support plate 370 at different locations, and can be implemented in substantially the same manner as the correspondingly positioned first belt 410 and second pulleys 440. The fourth pulley 460, connected to the third belt 410, guides the movement and direction of movement of the third belt 410. According to various embodiments, the number or position of belts or corresponding pulleys may vary, and is not limited to... Figure 3 Examples of implementations.

[0075] According to the embodiment, the sliding plate 120, the multi-bar structure 380, the flexible display 130, the support sheet 370, the first belt 410, the second belt 420, the third belt 430, the first pulley 360, the second pulley 440, the third pulley 450, and the fourth pulley 460 can be Figure 1a The closed state and Figure 2a Movement or force is transmitted during the switching between open and closed states. For example, the force used to move the sliding plate 120 on the first support member 310 can cause movement of the flexible display 130, movement of the first belt 410, movement of the second belt 420 and the third belt 430, rotation of the first pulley 360, rotation of the second pulley 440, rotation of the third pulley 450 and rotation of the fourth pulley 460. When the sliding plate 120 is moved a set distance by an external force, the electronic device 100 can be moved from the open state without additional external force due to at least one elastic structure 490. Figure 1a Switching to the closed state Figure 2a The sliding plate 120 can be moved from the open state to the closed state. The force used to move the sliding plate 120 on the first support member 310 may include an external force or a force generated by the elastic structure 490.

[0076] According to an embodiment, the flexible display 130 has a first flexible section 133, and the support sheet 370 has a second flexible section corresponding to the first flexible section 133 (for example, see...). Figure 6 The first flexible section 370 (reference numeral 373) and the multi-bar structure 380 can be connected to the first pulley 360. The movement and direction of movement of the first flexible section 133, the second flexible section, and the multi-bar structure 380 can be guided by the first pulley 360. The multi-bar structure 380 can be in face-to-face contact with the rollers 361 of the first pulley 360. The second flexible section of the support piece 370 can be located between the multi-bar structure 380 and the first flexible section 133 of the flexible display 130. The second flexible section of the support piece 370 does not directly contact the first pulley 360, but moves according to the driving relationship with the first pulley 360 based on the rotation of the first pulley 360, corresponding to the multi-bar structure 380. Therefore, in the following description, the second flexible section can be described as being in a connected state (or a driven connected state) with the first pulley 360. The first flexible section 133 does not directly contact the first pulley 360, but moves according to the driving relationship with the first pulley 360 based on the rotation of the first pulley 360, corresponding to the second flexible section of the multi-bar structure 380 and the support plate 370. Therefore, in the following description, the first flexible section 133 can be described as being in a connected state (or a driven connected state) with the first pulley 360.

[0077] According to an embodiment, a first belt 410 may be connected to a second pulley 440 positioned opposite to the first pulley 360, wherein the first pulley 360 is in a driven connection with the first flexible section 133 to provide tension to the flexible display 130 and the support sheet 370. A second belt 420 may be connected to a third pulley 450 positioned opposite to the first pulley 360, wherein the third pulley 450 is in a driven connection with the first flexible section 133 to provide tension to the flexible display 130 and the support sheet 370. A third belt 430 may be connected to a fourth pulley 460 positioned opposite to the first pulley 360, wherein the fourth pulley 460 is in a driven connection with the first flexible section 133 to provide tension to the flexible display 130 and the support sheet 370. The tension of the first belt 410, the tension of the second belt 420, and / or the tension of the third belt 430 may help to form a smooth connection of the first flexible section 133 to the screen of the first section 131 without lifting it up. The tension of the first belt 410, the tension of the second belt 420, and the tension of the third belt 430 can help enable the first flexible section 133 to be smoothly connected to the first section without lifting due to the elasticity of the flexible display 130 and / or the elasticity of the support sheet 370.

[0078] According to an embodiment, the third pulley 450 may be located between the second pulley 440 and the fourth pulley 460. The second pulley 440, the third pulley 450, and the fourth pulley 460 may be arranged along a direction from the second side cover 114 to the first side cover 113 (e.g., the +y axis direction). The distance between the third pulley 450 and the second pulley 440 along the +y axis direction may be substantially the same as the distance between the third pulley 450 and the fourth pulley 460 along the -y axis direction. According to an embodiment, the third pulley 450 may be positioned along the y axis direction corresponding to the center of the first segment 131 or the center of the screen. The distance between the third pulley 450 and the fourth support member 340 along the -y axis direction may be substantially the same as the distance between the third pulley 450 and the fifth support member 350 along the +y axis direction. The second pulley 440, the third pulley 450, and the fourth pulley 460 may be positioned with a distance substantially equal to that between them and the first pulley 360.

[0081] According to various embodiments, a belt or other pulleys corresponding to the belt and spaced apart from the first pulley 360 may be provided in an even number. The even-numbered pulleys may be arranged symmetrically along the y-axis relative to the center of the first segment 131 or the center of the screen.

A flexible display 130 may include a first segment 131 overlappingly coupled to the sliding plate 120. The flexible display 130 may include a first flexible segment 133 extending from the first segment 131, and the first flexible segment 133 may be pulled out from the internal space of the electronic device 100 while sliding out of the sliding plate 120. A support sheet 370 may be arranged on the rear surface of the flexible display 130. According to some embodiments, the support sheet 370 may be included within the flexible display 130. A first pulley 360 may be located inside the electronic device 100 and may be connected to the first flexible segment 133 of the flexible display 130. A first belt 410 may interconnect the support sheet 370 with the sliding plate 120. For example, one end 411 of the first belt 410 may be connected between the first support member 310 and the sliding plate 120. The support piece 370 may include a second segment (not shown), a second flexible segment (not shown), or a third segment (not shown), wherein the second segment is arranged at least partially along the first segment 131, the second flexible segment is arranged along the first flexible segment 133, or the third segment is spaced apart from the second segment if the second flexible segment is located between the second and third segments, and does not overlap with the flexible display 130. The other end 412 of the first band 410 may be connected to the third segment of the support piece 370. According to embodiments, the first band 410 may be connected to the sliding plate 120 by various methods, such as bolting, welding, or hooking. According to various embodiments, means are available to adjust the connection position between the first band 410 and the support piece 370. The tension of the first band 410 may vary depending on the connection position between the first band 410 and the support piece 370. According to some embodiments, means are available to adjust the connection position between the first band 410 and the sliding plate 120. The tension of the first belt 410 can vary depending on the connection position between the first belt 410 and the sliding plate 120. The second pulley 440 may have a rotation axis parallel to the first pulley 360 and may be arranged inside the electronic device 100 to be spaced apart from the first pulley 360 in the sliding direction (e.g., the +x axis direction). The second pulley 440 may be connected to the first belt 410. A multi-bar structure 380 may extend from the sliding plate 120 to the space between the support plate 370 and the first pulley 360. The multi-bar structure 380 may facilitate the first flexible section 133 to... Figure 4 The closed state and Figure 5 During the switching between open and closed states, it moves smoothly while remaining connected to the first segment 131 without rising. Figure 4 The closed state or Figure 5In the open state, a portion of the first flexible section 133 can form a first curved portion 130b of the screen, and the first curved portion 130b can be supported by a multi-bar structure 380 between the first pulley 360 and the first flexible section 133, so as to smoothly connect to the first section without raising it. Figure 5 In the open state, a portion of the first flexible section 133 can form a partially flat portion 130d of the screen, and the flat portion 130d can be formed by a surface 310b of the first support member 310 (e.g., Figure 3 A multi-bar structure 380 supports the area around the first recess 310c in a surface 310a and the first flexible section 133 to smoothly connect to the first section 131 without lifting.

For example, the force used to move the sliding plate 120 on the first support member 310 can cause movement of the flexible display 130, movement of the first belt 410, rotation of the first pulley 360, and rotation of the second pulley 440.

[0089] According to an embodiment, in Figure 4 The closed state or Figure 5 In the open state, the tension (belt tension) generated on the opposite side of the first belt 410 relative to the second pulley 440 is basically the same.

[0090] According to an embodiment, in Figure 4 The closed state and Figure 5 During the switching between open and closed states, the first band 410 can help enable the first flexible section 133 to move while remaining in the form of a smooth connection to the first section 131 without being raised.

[0091] For example, when electronic device 100 from Figure 4 Switching to the closed state Figure 5When in the open state, the sliding plate 120 can move along the +x axis on the first support member 310. Referring to the second pulley 440, a slack-side tension T3 can be generated on one side of the first belt 410 connected to the sliding plate 120, and a tension-side tension (or tensile-side tension) T4 can be generated on the other side of the first belt 410 connected to the support plate 370. According to the embodiment, the slack-side tension T3 and the tension-side tension T4 can be generated to make the first flexible section 133 movable while maintaining a shape that is smoothly connected to the first section 131 without lifting, while minimizing the loads applied to the rotation axis C1 of the first pulley 360 and the rotation axis C2 of the second pulley 440.

[0092] For example, when electronic device 100 from Figure 5 Switch the open state to Figure 4 In the closed state, the sliding plate 120 can move along the -x axis direction on the first support member 310. Referring to the second pulley 440, a tension-side tension T5 can be generated on one side of the first belt 410 connected to the sliding plate 120, and a relaxation-side tension T6 can be generated on the other side of the first belt 410 connected to the support plate 370. According to the embodiment, the tension-side tension T5 and the relaxation-side tension T6 can be generated to make the first flexible section 133 movable while maintaining a shape that is smoothly connected to the first section 131 without lifting, while minimizing the load applied to the rotation axis C1 of the first pulley 360 and the rotation axis C2 of the second pulley 440.

[0093] According to an embodiment, the stress acting on the first belt 410 may include stress due to tension (tensile stress) or stress due to bending (bending stress). Tensile stress may, for example, be proportional to the tension acting on the first belt 410 and inversely proportional to the cross-sectional area of ​​the first belt 410. Bending stress may be proportional to, for example, the vertical elastic modulus (the degree of resistance to tension or compression) of the first belt 410 and / or the thickness of the first belt 410, and inversely proportional to the diameter of the second pulley 440. To prevent the first belt 410 from... Figure 4 The closed state and Figure 5 The shape or material of the first strip 410 can be selected based on the tensile or bending stresses that may cause breakage during the switching between open and closed states. According to an embodiment, the first strip 410 may comprise stainless steel and may be implemented in the form of a thin strip.

[0094] According to various embodiments, Figure 3 The second band 420 or the third band 430 can be implemented in essentially the same way as the first band 410. Figure 3The third pulley 450 or the fourth pulley 460 can be implemented in a substantially the same way as the second pulley 420. The interaction operation between the second belt 420 and the third pulley 450, and the interaction operation between the third belt 430 and the fourth pulley 460, can be substantially the same as the interaction operation between the first belt 410 and the second pulley 440.

[0095] According to various embodiments (not shown), a first curved member including a first curved portion that contacts the multi-bar structure 380 may be arranged instead of the first pulley 360. For example, in Figure 4 The closed state and Figure 5 During the switching between open and closed states, the multi-bar structure 380 can slide relative to the first curved portion. According to various embodiments, to reduce friction between the first curved portion and the multi-bar structure 380, the surface of the first curved portion or the surface of the multi-bar structure 380 may be surface-treated.

According to some embodiments, the first pulley 360 may be defined as a first curved member, wherein the first curved member is implemented to be rotatable based on friction with the multi-bar structure 380. According to some embodiments (not shown), a track portion (not shown) for guiding the movement of the multi-bar structure 380 may be implemented by replacing the first curved member or by forming along a curved portion of the first curved member. The track portion may be formed in, for example... Figure 1a The housing 110 or Figure 3 The support member structure 300 is included. According to an embodiment, the fourth support member 340 may include a first track portion, wherein the first track portion is used to guide movement of the multi-bar structure 380 by inserting one side of the multi-bar structure 380 into the first track portion. The fifth support member 350 may include a second track portion, wherein the second track portion is used to guide movement of the multi-bar structure 380 by inserting the other side of the multi-bar structure 380 into the second track portion.

[0096] According to various embodiments (not shown), a second curved member, including a second curved portion that contacts the first belt 410, may be arranged instead of the second pulley 440. For example, in Figure 4 The closed state and Figure 5 During the switching between open and closed states, the first band 410 can slide relative to the second curved portion. According to various embodiments, to reduce friction between the second curved portion and the first band 380, the surface of the second curved portion or the surface of the multi-bar structure 380 can be surface-treated. According to various embodiments, the second curved member can be connected to... Figure 3 The support structure 300. According to some embodiments, the second pulley 440 may be defined as a second bending member, wherein the second bending member is made rotatable based on friction with the first belt 440.

The third bending member can be connected to Figure 3 The support structure 300. According to some embodiments, the third pulley 440 may be defined as a third bending member, wherein the third bending member is made rotatable based on friction with the second belt 450.

Figure 7b According to the embodiments Figure 6 A plan view of the rear surface of the display assembly 600 when the display assembly 600 is in the unfolded state.

[0100] Reference Figure 6 In an embodiment, the display assembly 600 may include a flexible display 130, a support sheet 370 disposed on the flexible display 130, or a flexible display 130 and... Figure 3 The printed circuit board 390 is an electrically interconnected flexible printed circuit board 135.

[0101] According to an embodiment, the flexible display 130 may be implemented based on a substrate (e.g., a plastic substrate) 610 formed of a flexible material (such as polyimide). Various layers (such as light-emitting layers and optical layers) may be arranged on the substrate 610 through a series of processes (such as deposition, patterning, and etching). The substrate 610 may be referred to as a “backplane” or “backplane substrate”. A portion 620 of the substrate 610 may extend outside the screen and may be electrically connected to a flexible printed circuit board 135. For example, the flexible printed circuit board 135 may be electrically connected to the extension 620 of the substrate 610 based on anisotropic conductive film (ACF) bonding. The flexible printed circuit board 135 may be electrically connected to the extension 620 of the substrate 610 through various other methods (e.g., connections between connectors). One end (not shown) of the flexible printed circuit board 135 may be electrically connected to the extension 620 of the substrate 610, and the other end (not shown) of the flexible printed circuit board 135 may be electrically connected to... Figure 3 , Figure 4 or Figure 5 The printed circuit board 390 shown is included. The flexible printed circuit board 135 may include a connector 135a for electrically connecting the flexible printed circuit board 135 to the printed circuit board 390.

[0102] According to an embodiment, a display driving circuit (e.g., a display driver integrated circuit (DDI)) 135b electrically connected to the light-emitting layer can be arranged on a flexible printed circuit board 135. A processor (e.g., an application processor (AP)) can be arranged on... Figure 3 , Figure 4 or Figure 5 On the printed circuit board 390, and the signal commanded by the processor can be sent to the display driver circuit 135b via the flexible printed circuit board 135.

[0103] According to embodiments, the flexible display 130 may be based on an OLED and may include an encapsulation layer disposed between the light-emitting layer and an optical layer (e.g., a circular polarization layer). The encapsulation layer may seal the light-emitting layer so that oxygen and / or moisture cannot permeate into the OLED. The encapsulation layer may be implemented as, for example, a thin-film encapsulation (TFE). According to various embodiments, the flexible display 130 may include conductive patterns, such as a metal mesh (e.g., an aluminum mesh), wherein the conductive patterns are disposed on the encapsulation layer as touch-sensitive circuitry between the encapsulation layer and the optical layer. For example, in response to bending of the flexible display 130, the metal mesh may have greater durability than a transparent conductive layer made of ITO.

[0104] According to an embodiment, the flexible display 130 may include a first segment 131 and a first flexible segment 133 extending from the first segment 131. The support sheet 370 may include a second segment 371, a third segment 372, or a second flexible segment 373. The second segment 371 may be arranged at least partially along the first segment 131. The second flexible segment 373 may be arranged at least partially along the first flexible segment 133. The third segment 372 may be spaced apart from the second segment 371 without overlapping the flexible display 130, provided that the second flexible segment 373 is located between the third segment 372 and the second segment 371.

[0105] According to an embodiment, the display assembly 600 may include a first fastening member 710, a second fastening member 720, or a third fastening member 730 disposed in the third segment 372. The first fastening member 710 may be connected to... Figure 3 The first belt 410. The second fastening component 720 can be connected to Figure 3 The second fastener 420 may be located between the first fastening member 710 and the third fastening member 730. The third fastening member 730 may be connected to Figure 3 The third zone, 430. (Refer to...) Figure 7b The support piece 370 may include a first edge 370a, a second edge 370b, a third edge 370c, or a fourth edge 370d. The second edge 370b may extend opposite to the first edge 370a and may be substantially parallel to the first edge 370a. The third edge 370c may interconnect one end of the first edge 370a with one end of the second edge 370b. The fourth edge 370d may interconnect the other end of the first edge 370a with the other end of the second edge 370b and may be substantially parallel to the third edge 370c. A first fastening member 710, a second fastening member 720, and a third fastening member 730 may be positioned adjacent to the second edge 370b. According to an embodiment, the distance between the first fastening member 710 and the second fastening member 720 may be substantially the same as the distance between the second fastening member 720 and the third fastening member 730.

[0106] According to various embodiments, Figure 3 The connection position between the support piece 370 and the first belt 410 is adjustable. Figure 3 The connection position between the support plate 370 and the second belt 420 is adjustable. Figure 3 The connection position between the support piece 370 and the third belt 430 is adjustable. The connection position between the support piece 370 and the belt (e.g., the first belt 410, the second belt 420, or the third belt 430) is adjustable such that the tension applied to the support piece 370 is within a threshold range. When the tension applied to the flexible display 130 and the attached support piece 370 is within the threshold range, the first flexible segment 133 can... Figure 1aThe closed state or Figure 2a In its open state, it remains smoothly connected to the shape of the first segment 131 without rising. When the tension applied to the flexible display 130 and the attached support sheet 370 is within a threshold range, the first flexible segment 133 can... Figure 1a The closed state and Figure 2a During the switching between open and closed states, it moves while maintaining a shape smoothly connected to the first segment 131 without rising. When the tension applied to the flexible display 130 and the attached support sheet 370 is within a threshold range, it can... Figure 1a The closed state and Figure 2a The sliding operation is performed smoothly during the transition between open and closed states.

[0107] For example, due to the connection position between the support piece 370 and the belt (e.g., the first belt 410, the second belt 420, or the third belt 430), the tension applied to the flexible display 130 and the attached support piece 370 may be below a threshold range. In this case, due to the elasticity of the flexible display 130 and / or the elasticity of the support piece 370, the first flexible segment 133 may rise or may be unevenly connected to the first segment 131.

[0108] As another example, due to the connection location between the support piece 370 and the belt (e.g., the first belt 410, the second belt 420, or the third belt 430), the tension applied to the flexible display 130 and the attached support piece 370 can exceed a threshold range. In this case, the first flexible segment 133 can be smoothly connected to the first segment 131 without lifting, but... Figure 1a The closed state and Figure 2a Sliding operations may be difficult to perform smoothly during the switching between open and closed states. When the tension applied to the flexible display 130 and the attached support plate 370 exceeds a threshold range, the load applied to the rotation axis of the pulleys (e.g., the first pulley 360, the second pulley 440, the third pulley 450, or the sixth pulley 460) may exceed the threshold and may increase the rotational resistance of the pulleys, making it difficult to perform smooth and gentle sliding operations.

[0109] According to an embodiment, the second flexible segment 373 may include a lattice structure 702, wherein the lattice structure 702 includes a plurality of openings (or a plurality of slits) 701 (see [link to embodiment]). Figure 7b For example, multiple openings 701 can be arranged periodically, can have substantially the same shape, and can be repeatedly arranged at regular intervals. Due to the lattice structure 702, the second bendable segment 373 can be more flexible than the second segment 371 or the third segment 372. The lattice structure 702 can contribute to the flexibility of the second bendable segment 373. The lattice structure 702 of the second bendable segment 373 is not limited to... Figure 7b This is one embodiment, and can be implemented in various other forms. According to various embodiments, the support sheet 470 may include a recessed pattern (not shown) comprising a plurality of recesses replacing the lattice structure 702, wherein the recessed pattern may contribute to the flexibility of the flexible display 130. According to various embodiments (not shown), the lattice structure 702 or the recessed pattern may further extend to at least a portion of the second segment 371.

[0110] According to an embodiment, the support sheet 370 allows components located inside the electronic device 100 to pass through... Figure 4 or Figure 5 The flexible display 130 is substantially invisible. For example, the lattice structure 702 of the second flexible segment 373 includes multiple openings 701, but is able to transmit light at a level where the multi-bar structure 380 is substantially invisible through the flexible display 130. According to various embodiments, the lattice structure 702 of the second flexible structure 373 includes multiple openings 701, but is also able to prevent the multiple bars of the multi-bar structure 380 from being seen through the flexible display 130 due to protrusion.

[0111] According to an embodiment, the display assembly 600 may include a support 740 connected to the first fastening member 710, the second fastening member 720, and the third fastening member 730 (see [link]). Figure 7b The support member 740 may be arranged adjacent to the second edge 370b of the support piece 370 and may extend along the second edge 370b. According to an embodiment, the support member 740 may be a rigid reinforcing substrate, and due to the support member 740, the first band 410 connected to the first fastening member 710 (see...) Figure 3 The tension can be dispersed and not concentrated in a localized area of ​​the support piece 370 (see reference numeral "761"). Due to the support piece 740, the second band 420 connected to the second fastening member 720 (see reference numeral "761") can be distributed. Figure 3 The tension can be dispersed and not concentrated in a localized area of ​​the support plate 370 (see reference numeral "762"). Due to the support member 740, the third band 430 connected to the third fastening member 730 (see reference numeral "762") can be distributed and not concentrated in a localized area of ​​the support plate 370. Figure 3 The tension can be dispersed rather than concentrated in a local area of ​​the support sheet 370 (see reference numeral "763" in the attached diagram).

[0112] According to various embodiments, the support member 740 may be integrated with the first fastening member 710, the second fastening member 720, and the third fastening member 730, and the support member and the fastening members may comprise the same material. According to various embodiments, the support member 740 may be integrated with the support sheet 370, and the support member and the support sheet may comprise the same material. According to various embodiments, the support member 740 may be implemented as part of the support sheet 370. For example, the support member 740 may be implemented with a structure in which a portion of the support sheet 370 is folded (e.g., a rolled edge structure).

[0113] Reference Figure 6 and 7a In an embodiment, the flexible display 130 may include a border region 137 adjacent to and provided along the edge 136 of the flexible display 130. The border region 137 may not include pixels implemented using light-emitting elements (such as OLEDs) and may include, for example, a black or black-based material with relatively low light transmittance. The border region 137 may be formed by various methods, such as coating or printing a light-shielding material onto a transparent cover forming the front surface of the flexible display 130. (See also...) Figure 2a In the open state, the bezel area 137 can be positioned between the screen and the mechanical structure while sliding out, contributing to the aesthetics of the electronic device 100. In one embodiment, referring to... Figure 1a In the closed state, a border region may be absent on the side of the opening (not shown) for introducing or pulling out the first flexible segment 133. However, in various embodiments, the border region can be implemented software-based at the boundary between the first segment 131 and the first flexible segment 133. The software-based border region can be implemented, for example, by not activating a portion of the flexible display 130 or by using an image displayed on a portion of the flexible display 130. According to various embodiments, the flexible display 130 can be implemented such that the border region 137 is minimized or substantially absent. In this case, the mechanical structure around the screen can be implemented in an elongated shape that allows it to slide out without sacrificing aesthetics, or in some cases, for Figure 1a The closed state or Figure 2a In the open state, the bezel area can be implemented in software. According to various embodiments, the signal lines and / or touch screen panel (TSP) electrodes of the flexible display 130 can be arranged in the bezel area 137.

(The remaining text is omitted.) Figure 8 Redundant descriptions of some of the reference numerals. When tension is applied to the support plate 370, the second segment 371 or the third segment 373 is not stretched, but the second flexible segment 373 may be stretched due to… Figure 7b The crystal structure 702 is stretched. According to an embodiment, the first reinforcing sheet 810, the second reinforcing sheet 820, and the third reinforcing sheet 830 prevent the second flexible segment 373 from being stretched. The first reinforcing sheet 810, the second reinforcing sheet 820, and the third reinforcing sheet 830 prevent the second flexible segment 373 from being stretched due to... Figure 7b The crystal lattice structure 702 is stretched, so that the tension of the first band 410, the tension of the second band 420, and the tension of the third band 430 are not reduced. Therefore, Figure 4 or Figure 5 The first flexible section 133 can be maintained in the shape of being smoothly connected to the first section 131 without being raised.

[0116] According to embodiments, the first reinforcing sheet 810, the second reinforcing sheet 820, or the third reinforcing sheet 830 may be joined to at least a portion of the second segment 371 and / or the third segment 372 by means such as welding. According to some embodiments, the first reinforcing sheet 810, the second reinforcing sheet 820, or the third reinforcing sheet 830 may additionally be joined to the second flexible segment 373. According to some embodiments, to reduce the deterioration of the flexibility of the second flexible segment 373, the first reinforcing sheet 810, the second reinforcing sheet 820, or the third reinforcing sheet 830 may not be joined to the second flexible segment 373, or may be joined in a manner that minimizes the joint area.

[0117] The first reinforcing piece 810 may, for example, extend from the second section 371 to the third section 372 via a second flexible section 373 between the first fastening member 710 and the second section 371. According to various embodiments, the first reinforcing piece 810 may be connected to the support member 740. The first reinforcing piece 810 may be provided to the second flexible section 373 by offering resistance to a first band 410 connected to the first fastening member 710 (see [link to relevant documentation]).

[0118] The second reinforcing piece 820 may, for example, extend from the second segment 371 to the third segment 372 across the second flexible segment 373 between the second fastening member 720 and the second segment 371. According to various embodiments, the second reinforcing piece 820 may be connected to the support member 740. The second reinforcing piece 820 may be provided to the second flexible segment 373 by offering resistance to a second band 420 connected to the second fastening member 720 (see...).

[0119] The third reinforcing piece 830 may, for example, extend from the second segment 371 to the third segment 372 across the second flexible segment 373 between the third fastening member 730 and the second segment 371. According to various embodiments, the third reinforcing piece 830 may be connected to the support member 740. The third reinforcing piece 830 may be provided to the second flexible segment 373 to resist a third band 430 connected to the third fastening member 730 (see [link to relevant documentation]). Figure 3 The tension of the second bendable section 373 is used to support the tension (e.g., tensile stress) to prevent stretching.

[0120] According to an embodiment, the first reinforcing sheet 810, the second reinforcing sheet 820, or the third reinforcing sheet 830 may be implemented to support the first flexible segment 133 of the flexible display 130 based on the tension of the first strip 410, the tension of the second strip 420, and the tension of the third strip 430 (see [link]). Figure 4 or Figure 5 The smooth bending of the first reinforcing strip 810 and the smooth bending of the second flexible section 373 of the support strip 370 can be achieved to have durability against tension. For example, the first reinforcing strip 810, the second reinforcing strip 820 and the third reinforcing strip 830 can be substantially unstretched due to the tension of the first strip 410, the tension of the second strip 420 and the tension of the third strip 430.
