Patent Description:
Advancing information communication and semiconductor technologies accelerate the spread and use of various electronic devices. In particular, recent electronic devices are being developed to carry out communication while carried on.

The term "electronic device" may mean a device performing a particular function according to its equipped program, such as a home appliance, an electronic scheduler, a portable multimedia player, a mobile communication terminal, a tablet PC, a video/sound device, a desktop PC or laptop computer, a navigation for automobile, etc. For example, electronic devices may output stored information as voices or images. As electronic devices are highly integrated, and high-speed, high-volume wireless communication becomes commonplace, an electronic device, such as a mobile communication terminal, is recently being equipped with various functions.

For example, an electronic device comes with the integrated functionality, including an entertainment function, such as playing video games, a multimedia function, such as replaying music/videos, a communication and security function for mobile banking, and a scheduling or e-wallet function. Such electronic devices become compact enough for users to carry in a convenient way.

As the demand for mobile communication increases, or as the degree of integration of electronic devices increases, the portability of electronic devices such as mobile communication terminals may be increased, and better convenience may be provided in use of multimedia functions. For example, as touchscreen-integrated displays replace traditional mechanical (button-type) keypads, electronic devices may come more compact while functioning as an input device. For example, as the mechanical keypad may be omitted from the electronic device, portability of the electronic device may be improved. As the display area may be expanded to the area which used to be occupied by the mechanical keypad, the electronic device may provide a larger screen while remaining in the same size and weight as when it has the mechanical keypad.

Use of an electronic device with a larger screen may give more convenience in, e.g., web browsing or multimedia playing. A larger display may be adopted to output a larger screen. However, this way may be limited by the portability of the electronic device. According to an embodiment, a display using organic light emitting diodes may secure the portability of the electronic device while providing a larger screen. For example, a display using, or equipped with, organic light emitting diodes may implement a stable operation even if it is made quite thin, so that the display may be applied to an electronic device in a foldable, bendable, or rollable form.

<CIT> discloses an electronic device, comprising a housing having first and second housing portions, a rotating roller within the first housing portion, a flexible display that is attached to the second housing portion and the rotating roller, and support members perpendicular to the first and second housing portions and extended entirely behind the flexible display.

In an electronic device in which mechanical structures move relative to each other, the relative movement of the structures may be smoothed by securing a certain distance between the mechanical structures. However, the gap between the mechanical structures may be a passage through which foreign substances are introduced. Foreign substances introduced into the electronic device may cause damage to the mechanical structures (e.g., a hinge structure or a roller) that perform a folding operation or a rolling operation, and damage may be caused due to scratches or crushing of an electronic component, such as the display.

A foldable or rollable electronic device may include a flexible display. The flexible display may be attached to the mechanical structure. Since the flexible display is flexible enough to be folded or rolled, it may be damaged due to friction or interference with foreign substances.

According to various embodiments of the disclosure, there may be provided an electronic device capable of preventing damage to a mechanical structure and/or an electronic component, such as a display, by blocking or removing an inflow of external foreign substances.

According to various embodiments of the disclosure, there may be provided an electronic device including a flexible display, which may block entry of foreign substances while allowing the flexible display to be folded or rolled more smoothly.

According to various embodiments of the disclosure, an electronic device comprises a first structure, a second structure receiving at least a portion of the first structure and guiding a sliding movement of the first structure, a flexible display including a first area connected with the first structure and a second area extending from the first area and being bendable, and a sweeper member configured to slide along an inside of the second structure while being attached to an end of the second area of the flexible display, according to the sliding movement of the flexible display.

According to various embodiments of the disclosure, the electronic device may provide a sweeper capable of removing foreign substances introduced into the inner space.

According to various embodiments of the disclosure, the electronic device may prevent scratches to the display or damage to the coating layer as the sweeper is attached to one end of the display to prevent the display from being rubbed due to the movement of the sweeper.

According to various embodiments of the disclosure, as the display slides, the electronic device may not only block an inflow of foreign substances but also discharge the introduced foreign substances to the outside.

According to an embodiment, the third plate 221c may be referred to as a "front case", and the first structure <NUM>, e.g., the first plate 211a, may be slid while substantially facing the third plate 221c. In some embodiments, the first sidewall 223a may be formed of a combination of a first sidewall portion 223a-<NUM> extending from the second plate 221a and a second sidewall portion 223a-<NUM> formed at an edge of the third plate 221c. According to another embodiment, the first sidewall portion 223a-<NUM> may be coupled to surround an edge of the third plate 221c, e.g., the second sidewall portion 223a-<NUM>. In this case, the first sidewall portion 223a-<NUM> itself may form the first sidewall 223a.

According to various embodiments, the supporting member 221d may be disposed in a space between the second plate 221a and the third plate 221c, and may have a flat plate shape formed of a metal or polymer. The supporting member 221d may provide an electromagnetic shielding structure in the internal space of the second structure <NUM> or may increase mechanical rigidity of the second structure <NUM>. In one embodiment, when received into the inside of the second structure <NUM>, a partial area (e.g., the second area A2) of the articulated hinge structure <NUM> and/or the display <NUM> may be positioned in a space between the second plate 221a and the supporting member 221d.

According to various embodiments, a printed circuit board (not shown) may be disposed in a space between the third plate 221c and the supporting member 221d. For example, the printed circuit board may be received in a space separated by the supporting member 221d from the space in which a partial area of the articulated hinge structure <NUM> and/or the display <NUM> is received inside the second structure <NUM>. A processor, memory, and/or interface may be mounted on the printed circuit board. The processor may include one or more of, e.g., a central processing unit, an application processor, a graphic processing device, an image signal processing, a sensor hub processor, or a communication processor.

The memory may include, e.g., a volatile or non-volatile memory.

The interface may include, e.g., a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, a secure digital (SD) card interface, and/or an audio interface. The interface may electrically or physically connect, e.g., the electronic device <NUM> with an external electronic device and may include a USB connector, an SD card/multimedia card (MMC) connector, or an audio connector.

According to various embodiments, the display <NUM> may be an organic light emitting diode-based flexible display, and the display <NUM> may normally remain in the flat shape and may be at least partially deformed into a curved shape. In one embodiment, the first area A1 of the display <NUM> may be mounted or attached to the first surface F1 of the first structure <NUM> and maintained in a substantially flat shape. The second area A2 may extend from the first area A1 and may be supported or attached to the articulated hinge structure <NUM>. For example, the second area A2 may extend along the sliding direction of the first structure <NUM> and, along with the articulated hinge structure, may be received in the second structure <NUM>. As the articulated hinge structure <NUM> is deformed, the second area A2 may be at least partially deformed into a curved shape.

According to various embodiments, as the first structure <NUM> slides on the second structure <NUM>, the area of the display <NUM> exposed to the outside may vary. The electronic device <NUM> (e.g., processor) may change the area of the display <NUM> that is activated based on the area of the display <NUM> that is exposed to the outside. For example, in the open state or in an intermediate position between the closed state and the open state, the electronic device <NUM> may activate a partial area exposed to the outside of the second structure <NUM> of the entire area of the display <NUM>. In the closed state, the electronic device <NUM> may activate the first area A1 of the display <NUM> and deactivate the second area A2. In the closed state, when there is no user input for a certain period of time (e.g., <NUM> seconds or <NUM> minutes), the electronic device <NUM> may deactivate the entire area of the display <NUM>. In some embodiments, in the state in which the entire area of the display <NUM> is deactivated, the electronic device <NUM> may activate a partial area of the display <NUM> as necessary (e.g., a notification according to user settings, missing call/received message notification) and provide visual information through the auxiliary display area (e.g., a portion of the second plate 221a and/or the rear plate 221b formed of a material that transmits light).

According to various embodiments, in the open state (e.g., the state shown in <FIG>), the entire area (e.g., the first area A1 and the second area A2) of the display <NUM> may be substantially exposed to the outside, and the first area A1 and the second area A2 may be arranged to form a plane. In one embodiment, even in the open state, a portion (e.g., one end) of the second area A2 may be positioned corresponding to the roller <NUM>, and the portion of the second area A2, which corresponds to the roller <NUM> may remain in the curved shape. For example, according to an embodiment, despite the phrase "the second area A2 is disposed to form a plane in the open state," a portion of the second area A2 may remain in the curved shape. Likewise, although it is stated that "in the closed state, the articulated hinge structure <NUM> and/or the second area A2 are received inside the second structure <NUM>," a portion of the second area A2 of the articulated hinge structure <NUM> may be positioned outside the second structure <NUM>.

According to an embodiment, the guide member, e.g., the roller <NUM>, may be rotatably mounted on the second structure <NUM> in a position adjacent to an edge of the second structure <NUM> (e.g., the second plate 221a). For example, the roller <NUM> may be disposed adjacent to an edge (e.g., the portion indicated with reference denotation 'IE') of the second plate 221a parallel to the first sidewall 223a. Although no reference denotation is assigned in the drawings, another sidewall may extend from the edge of the second plate 221a, and the sidewall adjacent to the roller <NUM> may be substantially parallel to the first sidewall 223a. As mentioned above, the sidewall of the second structure <NUM> adjacent to the roller <NUM> may be formed of a material that transmits light, and a portion of the second area A2 may provide visual information via the portion of the second structure <NUM> while being received in the second structure <NUM>.

According to various embodiments, an end of the roller <NUM> may be rotatably coupled to the second sidewall 223b, and the other end thereof may be rotatably coupled to the third sidewall 223c. For example, the roller <NUM> may be mounted on the second structure <NUM>, rotating about the rotation axis R perpendicular to the sliding direction (e.g., direction ① indicated with the arrow in <FIG> or <FIG>) of the first structure <NUM>. The rotation axis R may be disposed substantially parallel to the first sidewall 223a, and may be positioned away from the first sidewall 223a, for example, at one edge of the second plate 221a. In one embodiment, the gap formed between the outer circumferential surface of the roller <NUM> and the inner surface of the edge of the second plate 221a may form an entrance through which the articulated hinge structure <NUM> or display <NUM> enters the second structure <NUM>.

According to various embodiments, when the display <NUM> is deformed into a curved shape, the roller <NUM> maintains a radius of curvature of the display <NUM> to a certain degree, thereby suppressing excessive deformation of the display <NUM>. The term "excessive deformation" may mean that the display <NUM> is deformed to have a radius of curvature that is too small to damage pixels or signal lines included in the display <NUM>. For example, the display <NUM> may be moved or deformed while being guided by the roller <NUM> and may be protected from damage due to excessive deformation. In some embodiments, the roller <NUM> may rotate while the articulated hinge structure <NUM> or the display <NUM> is inserted into or extracted from the second structure <NUM>. For example, the friction between the articulated hinge structure <NUM> (or display <NUM>) and the second structure <NUM> may be suppressed, allowing the articulated hinge structure <NUM> (or display <NUM>) to smooth the insertion/extraction of the second structure <NUM>.

According to various embodiments, the electronic device <NUM> may further include a guide rail(s) <NUM> and/or an actuating member(s) <NUM>. The guide rail(s) <NUM> may be mounted on the second structure <NUM>, e.g., the third plate 221c to guide a sliding of the first structure <NUM> (e.g., the first plate 211a or the slide plate). The actuating member(s) <NUM> may include a spring or a spring module that provides an elastic force in a direction to allow both ends thereof to move away from each other. An end of the actuating member(s) <NUM> may be rotatably supported by the second structure <NUM>, and the other end may be rotatably supported by the first structure <NUM>. When the first structure <NUM> slides, both the ends of the actuating member(s) <NUM> may be positioned closest to each other (hereinafter, a 'nearest point') at any one point between the closed state and the open state. For example, in the interval between the nearest point and the closed state, the actuating member(s) <NUM> may provide an elastic force to the first structure <NUM> in a direction moving toward the closed state and, in the interval between the nearest point and the open state, the actuating member(s) <NUM> may provide an elastic force to the first structure <NUM> in a direction moving toward the open state.

In the following description, the components easy to understand from the description of the above embodiments are denoted with or without the same reference numerals and their detailed description may be skipped. According to an embodiment, an electronic device (e.g., the electronic device <NUM> of <FIG>) may be implemented by selectively combining configurations of different embodiments, and the configuration of one embodiment may be replaced by the configuration of another embodiment. However, it is noted that the disclosure is not limited to a specific drawing or embodiment.

<FIG> is a perspective view illustrating an arrangement relationship between a sweeper member <NUM> (hereinafter, simply "sweeper" <NUM>) and a surrounding structure according to various embodiments of the disclosure. <FIG> is a side view illustrating an arrangement relationship between a sweeper <NUM> and a surrounding structure and a movement path of the sweeper <NUM> according to various embodiments of the disclosure.

Referring to <FIG> and <FIG>, an electronic device <NUM> may include a first structure <NUM>, a second structure <NUM> (e.g., a housing), a flexible display <NUM> (hereinafter, simply "display" <NUM>), an articulated hinge structure <NUM>, and at least one sweeper <NUM> formed of a low-density elastic body, such as a sponge, or a brush. Hereinafter, the configuration of the first structure <NUM>, the second structure <NUM> (e.g., a housing), the display <NUM>, and the articulated hinge structure <NUM> of <FIG> and <FIG> may be identical in whole or part to the configuration of the first structure <NUM>, the second structure <NUM> (e.g., the housing), the display <NUM>, and the articulated hinge structure <NUM> of <FIG>.

According to various embodiments, the sweeper <NUM> may include at least three layers. The sweeper <NUM> may include an adhesive part <NUM>, a support part <NUM>, and a brush part <NUM>. The adhesive part <NUM>, the support part <NUM>, and the brush part <NUM> may be stacked. For example, the adhesive part <NUM> may be formed of an adhesive material, such as a double-sided tape, to attach the support part <NUM> to the second area A2. For example, the support part <NUM> may support the brush part <NUM> so that, when the sweeper <NUM> slides, at least a portion of the brush part <NUM> may move to tightly contact the inside of the second structure <NUM>. For example, the brush part <NUM> may be formed of a low-density elastic material, such as a sponge.

According to various embodiments, to prevent an inflow of foreign substances into the electronic device <NUM>, the thickness h of the sweeper <NUM> may be larger than the interval between the second plate 221a of the second structure <NUM> and the second areas A2 of the display <NUM>. According to an embodiment, the thickness h of the sweeper <NUM> may be set <NUM> to <NUM> wider than the interval between the second plate 221a of the second structure <NUM> and the second area A2 of the display <NUM>. For example, the length of the overlapping portion may be <NUM> to <NUM> or less. The thickness h of the sweeper <NUM> may be designed to easily prevent foreign substances d even with the smallest dimension, considering a tolerance of ±<NUM> for the thickness h of the sweeper <NUM> upon manufacturing the sweeper <NUM>. However, the configuration and size of the sweeper <NUM> are not limited to the above-described embodiment, and various design changes may be made thereto depending on the size or arrangement of surrounding structures. According to various embodiments, when the sweeper <NUM> slides according to the sliding movement of the first structure <NUM>, it may overlap the inner surface of the second plate 221a of the second structure <NUM>, preventing an inflow of foreign substances d.

According to various embodiments, the sweeper <NUM> may be disposed substantially in the internal space of the second structure <NUM>. For example, the sweeper <NUM> may be attached to one end of the second area A2 of the display <NUM> and may slide along the inside of the second structure <NUM> in response to the sliding movement of the first structure <NUM>. Accordingly, since the sweeper <NUM> slides together with the first structure <NUM> and the display <NUM>, the rubbing of the display <NUM> due to the movement of the sweeper <NUM> may be avoided, preventing scratches to the display <NUM> or damage to the coating layer (e.g., anti-finger (AF) coating).

According to various embodiments, when the sweeper <NUM> is driven, the layer attached to the first structure <NUM> may be the adhesive part <NUM>, and the layer overlapping the second structure <NUM> may be the brush part <NUM>. The brush part <NUM> may be formed of a soft material, and when the sweeper <NUM> slides, it may move smoothly, thereby preventing malfunction due to an overlap between the sweeper <NUM> and the second plate 221a.

According to various embodiments, when the first structure <NUM> moves from the closed state to the open state with respect to the second structure <NUM>, the sweeper <NUM> may come in contact with the second plate 221a while moving toward an edge of the second plate 221a in the second direction (e.g., direction ②).

According to various embodiments, if the first structure <NUM> reaches the open state, the sweeper <NUM> may contact the inner surface of the edge of the second plate 221a. In this case, the sweeper <NUM> may block the inflow of foreign substances by sealing the gap between the inner surface of the edge of the second plate 221a and the surface of the display <NUM>.

<FIG> is an enlarged cross-sectional view illustrating a structure of a flexible display <NUM> (hereinafter, simply "display" <NUM>) according to one of various embodiments of the disclosure.

Referring to <FIG>, an electronic device <NUM> may include a first structure (e.g., the first structure <NUM> of <FIG>), a second structure <NUM> (e.g., a housing), a display <NUM>, an articulated hinge structure (e.g., the articulated hinge structure <NUM> of <FIG> and <FIG>), and at least one sweeper member <NUM> (hereinafter, simply "sweeper") formed of a low-density elastic body, such as a sponge, or a brush. Hereinafter, the configuration of the first structure (e.g., the first structure <NUM> of <FIG>), the second structure <NUM> (e.g., the housing), the display <NUM>, and the articulated hinge structure <NUM> of <FIG> may be identical in whole or part to the configuration of the first structure <NUM>, the second structure <NUM> (e.g., the housing), the display <NUM>, and the articulated hinge structure <NUM> of <FIG> and <FIG>.

According to various embodiments, a second area A2 of the display <NUM> may include a <NUM>-1th area A2-<NUM> extending from a first area A1 and a <NUM>-2th area A2-<NUM> extending from the <NUM>-1th area A2-<NUM>. However, the segmentation of the display <NUM> as shown in <FIG> is merely an example, and the display <NUM> may be divided into a plurality of (e.g., four or more, or two) areas depending on the structure or function of the display <NUM>.

According to various embodiments, the display <NUM> may include a plurality of layers. For example, in the display <NUM>, a display panel layer 203a, a protection layer 203b, and a metal layer 203c may be sequentially stacked. The protection layer 203b may cover the display panel 203a from external impact and/or foreign substances so that the display panel 203a is not damaged. The protection layer 203b may extend along one surface or a side surface of the display panel 203a and may seal the display panel 203a.

According to an embodiment, the <NUM>-1th area A2-<NUM> may be composed of layers including the display panel layer 203a and the protection layer 203b, and the <NUM>-2th area A2-<NUM> may be composed of layers other than the display panel layer 203a. For example, the <NUM>-2th area A2-<NUM> may include the protection layer 203b or the metal layer 203c which is not related to damage to the display panel, except for the display panel layer 203a. The protection layer 203b of the <NUM>-2th area A2-<NUM> may be formed to surround the side surface of the display panel layer 203a of the <NUM>-1th area A2-<NUM>, protecting the display panel 203a from external impact and/or foreign substances.

According to various embodiments, the sweeper <NUM> may be attached to one end of the <NUM>-2th area A2-<NUM> of the display <NUM>. When the sweeper <NUM> is attached to the display <NUM>, a pressing process may be required to secure the adhesive strength, and damage to the display may be induced by the pressure caused by the pressing process. In this case, when the layers other than the display panel layer 203a are damaged, the use of the electronic device <NUM> is not affected, but when the display panel layer 203a is damaged, the use of the electronic device <NUM> may be affected. Accordingly, as the sweeper <NUM> is attached to one end of the <NUM>-2th area A2-<NUM>, the display panel layer 203a may be prevented from damage due to the attachment and driving of the sweeper <NUM>.

<FIG> is a view illustrating a path along which foreign substances d are introduced into the inside according to various embodiments of the disclosure. <FIG> is a view illustrating an operation in which foreign substances d introduced into the inside are discharged to the outside through a sweeper member <NUM> (hereinafter, simply "sweeper" <NUM>) according to various embodiments of the disclosure.

Referring to <FIG> and <FIG>, an electronic device <NUM> may include a first structure <NUM>, a second structure <NUM> (e.g., a housing), a flexible display <NUM> (hereinafter, simply "display" <NUM>), an articulated hinge structure <NUM>, and a sweeper <NUM>. Hereinafter, the configuration of the first structure <NUM>, the second structure <NUM> (e.g., a housing), the display <NUM>, and the articulated hinge structure <NUM> of <FIG> and <FIG> may be identical in whole or part to the configuration of the first structure <NUM>, the second structure <NUM> (e.g., the housing), the display <NUM>, and the articulated hinge structure <NUM> of <FIG>.

According to various embodiments, foreign substances d may be introduced through the gap between the second plate 221a of the second structure <NUM> and the second area A2 of the display <NUM>. However, due to the sweeper <NUM> having a thickness h larger than the interval between the second plate 221a of the second structure <NUM> and the second area A2 of the display <NUM>, the foreign substances d may be prevented from entry.

According to various embodiments, foreign substances d may be introduced through the gap between the second plate 221a of the second structure <NUM> and the second area A2 of the display <NUM>. In this case, the sweeper <NUM> that slides together with the first structure <NUM> sliding from the closed state to the open state may sweep the foreign substances d in the second direction (e.g., direction ②), discharging the foreign substances d to the outside.

<FIG> is a view illustrating a configuration of a chamfer <NUM> according to one of various embodiments of the disclosure.

Referring to <FIG>, an electronic device <NUM> may include a first structure <NUM>, a second structure <NUM> (e.g., a housing), a flexible display <NUM> (hereinafter, simply "display" <NUM>), an articulated hinge structure <NUM>, a sweeper member <NUM> (hereinafter, simply "sweeper" <NUM>), and a chamfer <NUM> formed at a designated angle θ. Hereinafter, the configuration of the first structure <NUM>, the second structure <NUM> (e.g., the housing), the display <NUM>, the articulated hinge structure <NUM>, and the sweeper <NUM> of <FIG> may be identical in whole or part to the configuration of the first structure <NUM>, the second structure <NUM> (e.g., the housing), the display <NUM>, the articulated hinge structure <NUM>, and the sweeper <NUM> of <FIG> and <FIG>.

According to various embodiments, when the chamfer <NUM> is formed at an end of the second plate 221a of the second structure <NUM>, it may help to discharge the foreign substances d. According to an embodiment, at least a portion of the second plate 221a may form the chamfer <NUM>. According to another embodiment, the second structure <NUM> may further include the second plate 221a and the chamfer <NUM> extending from one end of the second plate 221a.

According to various embodiments, the chamfer <NUM> may be formed at an end of the second structure <NUM> that is bent upward along the shape of the articulated hinge structure <NUM> connected with one end of the first structure <NUM>. For example, the position where the chamfer <NUM> is formed may be a portion where the sweeper <NUM> contacts the second plate 221a of the second structure <NUM> when the first structure <NUM> is in the open state.

According to various embodiments, the direction of the sliding movement of the display <NUM> may be defined as an x-axis direction. Further, a direction perpendicular to the x-axis direction may be defined as a y-axis direction. The chamfer <NUM> may be formed by cutting a corner portion connecting the upper surface (xy plane) and the inner surface of the end of the second structure <NUM> at a designated angle θ and extending it in the y-axis direction. The designated angle θ may be larger than or equal to <NUM>° and less than <NUM>°. For example, the designated angle θ may be about <NUM>°.

According to various embodiments, in the open state of the first structure <NUM>, a second gap @ between one surface of the chamfer <NUM> and the display <NUM> may be wider than a first gap ⓑ between the second plate 221a of the second structure <NUM> and the display <NUM>. Accordingly, when the first structure <NUM> slides from the closed state to the open state, the gap of the portion in contact with the sweeper <NUM> in the open state is widened, allowing the foreign substances d to be easily discharged.

<FIG> is a view illustrating a form in which processing has been performed to widen a gap between a second plate 221a of a second structure <NUM> and a second area A2 of a flexible display <NUM> (hereinafter, simply "display" <NUM>) according to one of various embodiments of the disclosure.

Referring to <FIG>, an electronic device <NUM> may include a first structure <NUM>, a second structure <NUM> (e.g., a housing), a display <NUM>, an articulated hinge structure <NUM>, a sweeper member <NUM> (hereinafter, simply "sweeper" <NUM>), and a chamfer <NUM>. Hereinafter, the configuration of the first structure <NUM>, the second structure <NUM> (e.g., the housing), the display <NUM>, the articulated hinge structure <NUM>, the sweeper <NUM>, and the chamfer <NUM> of <FIG> may be identical in whole or part to the configuration of the first structure <NUM>, the second structure <NUM> (e.g., the housing), the display <NUM>, the articulated hinge structure <NUM>, the sweeper <NUM>, and the chamfer <NUM> of <FIG>.

According to various embodiments, in the closed state of the first structure <NUM>, the foreign substances d may not enter from the position (e.g., the <NUM>-2th area A2-<NUM>) where the sweeper <NUM> is attached to the inside of the electronic device due to the sweeper <NUM>. However, up to the portion where the sweeper <NUM> is attached, the foreign substances d may be introduced through the passage between the second plate 221a of the second structure <NUM> and the second area A2 of the display <NUM>. In this case, the inner surface of the second structure <NUM> may be recessed downward to prevent the risk of damage to the display <NUM> due to the introduced foreign substances d. According to various embodiments, a recessed surface, such as a dent, may be defined as a recess. According to an embodiment, it is possible to widen the gap between the second plate 221a of the second structure <NUM> and the <NUM>-2th area A2-<NUM> of the display <NUM> by cutting the inner surface of the second plate 221a of the second structure <NUM>. For example, the inner surface of the second structure <NUM> may be recessed downward as compared with the end of the second structure <NUM> which is bent upward along the shape of the articulated hinge structure <NUM> connected with one end of the first structure <NUM>, i.e., the inlet where the foreign substances d are introduced. For example, the inner surface of the second plate 221a of the second structure <NUM> may be recessed by about <NUM>.

According to various embodiments, the section where the inner surface of the second plate 221a is cut may be a section from the portion a in contact with the sweeper <NUM> when the first structure <NUM> is in the closed state to the portion b in contact with the sweeper <NUM> when the first structure <NUM> is in the open state.

According to various embodiments, cutting the inner surface of the second plate 221a of the second structure <NUM> may be defined as slimming. In the process of slimming, the overlapping thickness between the sweeper <NUM> and the second structure <NUM> may be decreased, thereby reducing the effect of preventing foreign substances. To prevent this, the thickness of the brush part <NUM> of the sweeper <NUM> may be extended. According to various embodiments, the thickness of the brush part <NUM> of the sweeper <NUM> may be extended, corresponding to the thickness of the recessed portion of the second structure <NUM>. In an embodiment, the thickness of the brush part <NUM> of the sweeper <NUM> may be increased by <NUM>, corresponding to the dimensions of cutting the inner surface of the second plate 221a of the second structure <NUM>. Thus, even while the sweeper <NUM> passes the slimming area, the overlapping thickness between the sweeper <NUM> and the second structure <NUM> may remain constant, thus preventing an inflow of foreign substances d due to the overlap and damage to the display <NUM> due to the foreign substances d introduced into the inside.

According to various embodiments of the disclosure, an electronic device (e.g., the electronic device <NUM> of <FIG>) comprises a first structure (e.g., the first structure <NUM> of <FIG>), a second structure (e.g., the second structure <NUM> of <FIG>) receiving at least a portion of the first structure <NUM> and guiding a sliding movement of the first structure <NUM>, a flexible display (e.g., the flexible display <NUM> of <FIG>) including a first area A1 connected with the first structure <NUM> and a second area A2 extending from the first area A1 and bendable, and a sweeper member <NUM> formed to slide along an inside of the second structure <NUM> while being attached to an end of the second area A2 of the flexible display <NUM>, corresponding to the sliding movement of the flexible display <NUM>.

According to various embodiments, a length of the overlapping portion may be <NUM> or more and <NUM> or less, reflecting dimensional tolerances of the sweeper and the structure.

According to various embodiments, the overlapping portion may be a brush part <NUM> of the sweeper member <NUM>.

According to various embodiments, the sweeper member <NUM> may slide to sweep out a foreign substance d introduced through a gap between the flexible display <NUM> and the second structure <NUM>.

According to various embodiments, the sweeper member <NUM> may contact an inner surface of an edge of the second structure <NUM> to block an inflow of an external foreign substance d, in an open state of the first structure <NUM> with respect to the second structure <NUM>.

According to various embodiments, an inner surface of the second structure <NUM> may be recessed downward as compared with an inlet portion which is an end of the second structure <NUM> bent upward along a shape of the articulated hinge structure <NUM>.

According to various embodiments, a recessed section of the second structure <NUM> may be from a portion in contact with the sweeper member <NUM> in a closed state of the first structure <NUM> with respect to the second structure <NUM> to a portion in contact with the sweeper member <NUM> in an open state of the first structure <NUM> with respect to the second structure <NUM>.

According to various embodiments, a thickness of a brush part <NUM> of the sweeper <NUM> may be extended corresponding to a thickness of the recessed portion of the second structure <NUM>.

According to various embodiments, the thickness of the recessed portion of the second structure <NUM> and the thickness of the extension of the brush part <NUM> of the sweeper member <NUM> may be <NUM>.

According to various embodiments, the electronic device may further comprise a chamfer <NUM> formed at an end of the second structure <NUM> to easily discharge a foreign substance d according to the sliding movement of the sweeper member <NUM>.

According to various embodiments, the chamfer <NUM> may be formed in a corner portion connecting an inner surface and an upper surface of an end bent upward along a shape of an articulated hinge structure <NUM> in the second structure <NUM>.

According to various embodiments, the chamfer <NUM> may be formed at a designated angle θ with respect to an end of the second structure <NUM> and may be formed to extend in a direction perpendicular to a direction of the sliding movement of the flexible display <NUM>.

According to various embodiments, an interval between one surface of the chamfer <NUM> and the flexible display <NUM> may be larger than an interval between an inner surface of the second structure <NUM> and the flexible display <NUM>.

According to various embodiments, an electronic device <NUM> may comprise a first structure (e.g., the first structure <NUM> of <FIG>), a second structure (e.g., the second structure <NUM> of <FIG>) receiving at least a portion of the first structure <NUM> and guiding a sliding movement of the first structure <NUM>, a flexible display <NUM> including a first area A1 connected with the first structure <NUM> and a second area A2 extending from the first area A1 and bendable, the second area A2 including a <NUM>-1th area A2-<NUM> extending from the first area A1 and in which a display panel and a protection layer are stacked, and a <NUM>-2th area A2-<NUM> extending from the <NUM>-1th area and in which the protection layer is positioned and the display panel is excluded, and a sweeper member <NUM> attached onto the <NUM>-2th area A2-<NUM> of the flexible display <NUM>.
