Description

Technology Field

[0001] Various embodiments of the present disclosure relate to rollable electronic devices. Background Technology

[0002] Electronic devices are becoming increasingly slimmer and are being improved to increase rigidity, enhance design aspects, and differentiate functional elements. Electronic devices are moving away from uniform rectangular shapes and are gradually transforming into various shapes. Electronic devices can have a deformable structure that allows for convenient portability and the use of large-screen displays. For example, as an example of a deformable structure, an electronic device may have a structure (e.g., a rollable structure or a sliderable structure) that can vary the display area of ​​a flexible display through the support of housings that operate in a sliding manner relative to each other. A rollable electronic device (or a sliderable electronic device) can be configured so that the flexible display can be rolled up or unfolded. A sliderable electronic device can be configured so that the flexible display moves in a sliding manner to expand and contract the screen. The problem to be solved

[0003] When a bendable section of a display moves in a first direction (e.g., x-axis direction) through a curved portion of an electronic device, a compressive force is applied, and the spacing between the multi-bars of the bendable member narrows. When the spacing between the multi-bars narrows, interference between the multi-bars may occur, and local compressive and tensile stresses may be generated in the section between the multi-bars. Due to these compressive and tensile stresses, the display may lift and deform. Various embodiments of the present disclosure may provide a bending plate capable of reducing tensile stress caused by the narrowing of the spacing between the multi-bars in the curved portion of an electronic device, and an electronic device including the same. means of solving the problem

The second housing may be slid in a first direction so that at least a portion is withdrawn from the first housing, and may be slid in a second direction so that at least a portion is drawn into the first housing. The flexible display may be disposed in a space formed by the first housing and the second housing and may include a first region that is visually visible to the outside and a second region that extends from the first region, is received internally in a closed state, and is visually visible to the outside in an open state. The bendable member may include a plurality of multi-bars disposed on the back surface of the flexible display to support the flexible display in the closed state and the open state, and arranged at a certain interval. The bending plate may be attached to the flexible display and the plurality of multi-bars.

[0005] A display assembly according to various embodiments of the present disclosure may include a flexible display, a bendable member, and a bending plate, in a display assembly of an electronic device. The flexible display may include a first region positioned to be visible from the outside and a second region extending from the first region, which is received internally in a closed state and positioned to be visible from the outside in an open state. The bendable member may include a plurality of multi-bars positioned at a certain interval, which are positioned on the back surface of the flexible display to support the flexible display in the closed state and the open state. The bending plate may be attached to the lower part of the flexible display and may be attached to the plurality of multi-bars.

[0006] The technical problems to be solved by the present invention are not limited to those mentioned above, and other technical problems not mentioned can be clearly understood by those skilled in the art to which the present invention belongs from the description below. Effects of the invention

[0007] An electronic device according to various embodiments of the present disclosure may place a bending plate between a display and a bendable member so that the bendable member is flexibly bent by the bending plate, thereby reducing the compressive force and tensile stress applied to the multi-bars at the bending portion of the electronic device, and thus reducing the lifting or deformation of the display.

[0057] FIG. 3 is a drawing showing a front surface (e.g., a first surface) (e.g., a surface on which a screen is displayed) in a first state (e.g., a closed state) of an electronic device according to various embodiments of the present disclosure. FIG. 4 is a drawing showing a front surface (e.g., a first surface) (e.g., a surface on which a screen is displayed) in a second state (e.g., an open state) of an electronic device according to various embodiments of the present disclosure. FIG. 5 is a drawing showing a rear surface (e.g., a second surface) in a second state (e.g., an open state) of an electronic device according to various embodiments of the present disclosure.

[0058] The electronic device (300) of FIGS. 3 to 5 may be at least partially similar to the electronic device (101) of FIG. 1 or the electronic device (300) of FIG. 2, or may further include other embodiments of the electronic device.

[0059] Referring to FIGS. 3 through 5, a display (310) of an electronic device (300) according to various embodiments of the present disclosure may include an extended area (312) and a fixed area (314). In an open state (e.g., a second state) of the electronic device (300) according to various embodiments of the present disclosure, the fixed area (314) may be supported by one area of ​​a bendable member (e.g., a bendable member (620) of FIGS. 6 and 7). Additionally, in an open state (e.g., a second state) of the electronic device (300), the extended area (312) may be supported by another area of ​​a bendable member (e.g., a bendable member (620) of FIGS. 6 and 7). Accordingly, the fixed area (314) of the display (310) supported by the bendable member (e.g., a bendable member (620) of FIGS. 6 and 7) may form a plane. Additionally, some of the extended area (312) of the display (310) may form a flat surface by a support plate (e.g., support plate (641) of FIG. 6), and other parts may form a curved surface by a curved area (e.g., sliding bar (634) of FIG. 6) (e.g., a pressing part) of the support plate (e.g., support plate (641) of FIG. 6).

[0060] As an example, in a closed state (e.g., a first state) of the electronic device (300), at least a portion of a bendable member (e.g., a bendable member (620) of FIG. 6) may be received inside a second housing (370) (e.g., a second housing (660) of FIG. 6). The bendable member (e.g., a bendable member (620) of FIG. 6) may be supported by a sliding bar (e.g., a pressure member (643) of FIG. 6) of the electronic device (300) and may be drawn into the space between a support plate (e.g., a support plate (641) of FIG. 6) and the second housing (370) (e.g., a second housing (660) of FIG. 6). In this case, at least some portion of the bendable member (e.g., the bendable member (620) of FIG. 6 and 7) may come into contact with a driving member (e.g., the joining link (645) of FIG. 6).

[0061] In one embodiment, although not illustrated, the bendable member (e.g., the bendable member (620) of FIGS. 6 and 7) may be formed as a plate (e.g., a support plate) having a region substantially corresponding to the fixed region (314). At least a portion of the display (310) (e.g., a bendable section) (e.g., an extended region (312)) may be positioned so as not to be seen from the outside by being received into the internal space of the second housing (370) (e.g., the second housing (660) of FIGS. 6) while being supported by the bendable member (e.g., the bendable member (620) of FIGS. 6 and 7) in a closed state (e.g., a first state).

[0062] According to one embodiment, at least a portion of the display (310) (e.g., a bendable section) (e.g., an extended area (312)) may be positioned to be visible from the outside while being supported by a bendable member (620) in an open state (e.g., a second state).

[0063] According to one embodiment, the electronic device (300) may include a front surface (301) on which the screen of the display (310) is displayed, a rear surface (302) facing in the opposite direction to the front surface (301), and a side surface (303) surrounding the space between the front surface (301) and the rear surface (302).

[0064] According to one embodiment, the front (301) and rear (302) of the electronic device (300) may vary in area depending on the state of the electronic device (300) (e.g., open state or closed state). For example, when the electronic device (300) is in an open state (e.g., the open state of FIG. 4), the area of ​​the front (301) of the electronic device (300) (e.g., screen area) may be expanded as the bendable section (e.g., extended area (312)) of the display (310) is extended. For example, when the electronic device (300) is in a closed state (e.g., the closed state of FIG. 3), the area of ​​the rear (302) of the electronic device (300) may include the area of ​​the back cover (e.g., the back cover (330) of FIG. 2, the back cover (690) of FIG. 6) (e.g., rear cover). Additionally, when the electronic device (300) is in an open state, the area of ​​the rear surface (302) of the electronic device (300) may include the area of ​​the back cover (e.g., back cover (330) of FIG. 2, back cover (690) of FIG. 6) (e.g., rear cover) and the area substantially corresponding to the bendable area of ​​the rear surface of the second housing (370) (e.g., second housing (660) of FIG. 6).

[0065] According to one embodiment, the display (310) may include a fixed area (314) that is always visually visible to the outside and an extended area (312) that is visually visible to the outside when in an open state (e.g., a second state). The extended area (312) is visually visible to the outside only when the electronic device (300) is in an open state (e.g., a second state), and the fixed area (314) may be visually visible to the outside when in a closed state (e.g., a first state) and an open state (e.g., a second state). For example, the extended area (312) extends from the fixed area (314) and may be drawn inward or drawn outward depending on the movement of the second housing (370) (e.g., the second housing (660) of FIG. 6).

[0066] According to one embodiment, the display (310) can have an extended area (312) extended while being supported by a bendable member (620) (e.g., FIGS. 6 and 7) in an open state along a first direction (e.g., -x axis direction). In this case, at least a portion of the fixed area (314) and the extended area (312) can form substantially the same plane.

[0067] According to one embodiment, the size (or area) of the display area of ​​the display (310) of the electronic device (300) can be varied as the second housing (370) (e.g., the second housing (660) of FIG. 6) and the support plate (e.g., the support plate (641) of FIG. 6) move in a sliding manner in a first direction (e.g., -x-axis direction) or in a second direction (e.g., x-axis direction) opposite to the first direction (e.g., -x-axis direction).

[0068] According to one embodiment, the operation of the closed state (e.g., first state) (e.g., screen expansion, slide out) and / or the open state (e.g., second state) (e.g., screen reduction, slide in) of the electronic device (300) can be performed manually through user operation.

[0069] According to one embodiment, the operation of the closed state (e.g., first state) (e.g., screen expansion, slide out) and / or the open state (e.g., second state) (e.g., screen reduction, slide in) of the electronic device (300) can be performed automatically or semi-automatically using a driving device (e.g., motor, ball screw, cam, slider crank, or hinge).

[0070] FIG. 6 is an exploded perspective view of an electronic device according to various embodiments of the present disclosure.

[0071] Referring to FIG. 6, an electronic device (600) (e.g., electronic device (300) of FIG. 3 and 4) according to various embodiments of the present disclosure may include a display (610) (e.g., display (310) of FIG. 2, display (310) of FIG. 3 and 4), a bendable member (620), a first housing (630), a support assembly (640), a guide rail (650), a second housing (660) (e.g., second housing (370) of FIG. 3 and 4), a printed circuit board (670), a battery (680), and a back cover (690) (e.g., back glass) (e.g., rear cover).

[0077] According to one embodiment, the electronic device (600) may include a camera module (e.g., camera module (305) of FIG. 3) and a sensor module (e.g., sensor module (307) of FIG. 3) placed in a first space (661).

[0078] According to one embodiment, the bendable member (620) may be positioned such that one end is fixed to the first housing (630) and the other end is movably received at least partially in the second space (662) of the second housing (660). For example, the bendable member (620) may be received at least partially in the second space (662) in the retracted state. In the extended state, the bendable member (620) may be withdrawn at least partially from the second space (662) to form substantially the same plane as the first housing (630) (e.g., the second bracket housing (630b)). Accordingly, the display (610), supported by at least a portion of the first housing (630) and the bendable member (620), may have a display area visible from the outside that can be varied according to the sliding motion.

[0079] According to one embodiment, the electronic device (600) may be disposed between the first housing (630) and the second housing (660) and may include at least one guide rail (650) for inducing a sliding motion of the second housing (660). In some embodiments, the electronic device (600) may further include a cover member (not shown) disposed to cover both sides of the first housing (630) (e.g., the third side (303c) and the fourth side (303d) of FIG. 2 and FIG. 3).

[0080] According to various embodiments, the electronic device (600) may include a support assembly (640).

For example, the bending plate (e.g., the bending plate (1320) of FIG. 13) may connect a plurality of bars to support a fixed section (e.g., the fixed section (610a) of FIG. 10).

[0095] According to one embodiment, the support assembly (640) can slide in the -x-axis direction and the x-axis direction according to the movement of the second housing (660) to expand or contract the screen of the display (610). For example, the support assembly (640) can expand the screen of the display (610) by pushing the bendable member (620) in the x-axis direction. Alternatively, when the second housing (660) moves in the -x-axis direction due to an external force, the support assembly (640) can contract the screen of the display (610) by pushing the bendable member (620) in the -x-axis direction. The support assembly (640) can support at least a portion of the bendable member (620) of the bendable part (e.g., the bendable part (601) of FIG. 10) where the display (610) is bent. Additionally, the support assembly (640) can support a bendable member (620) in a flat area (e.g., a flat area (602) of FIG. 10) other than a curved part (e.g., a curved part (601) of FIG. 10) when the screen of the display (610) is expanded.

[0096] FIG. 9 is a drawing showing a guide rail according to various embodiments of the present disclosure.

[0097] Referring to FIGS. 6, 8, and 9, the guide rail (650) may include a side body (652) forming at least one side of the electronic device (600), and a guide groove (654) into which at least a part (e.g., a guide projection (624)) of the display (610) and / or bendable member (620) is inserted to guide the movement of the bendable member (620). The guide rail (650) may provide a path for the display (610) and / or bendable member (620) to move through the guide groove (654). For example, the guide rail (650) may be positioned in the y-axis direction and the -y-axis direction, respectively, inside the second housing (670). The guide rail (650) allows the bendable section of the display (610) (e.g., the bendable section (610b) of FIG. 10) to be drawn into or drawn out of the second housing (670) along the guide rail (650), thereby allowing the display (610) to be drawn into or drawn out in a shape that is smoothly connected to the side of the second housing (670).

[0098] In one embodiment, the first housing (630) accommodates at least a portion of the second housing (660) and is combined with the second housing (660) to protect electronic components placed inside the electronic device (600) and to form the exterior of the electronic device (600).

[0099] According to one embodiment, the second housing (660) can be slid in a first direction (e.g., the x-axis direction of FIGS. 2 and 3) when moving to expand the screen of the display (610). According to one embodiment, the second housing (660) can be slid in a second direction (e.g., the -x-axis direction of FIGS. 2 and 3) when moving to reduce the screen of the display (610).

[0100] According to one embodiment, a back cover (690) (e.g., back glass) is located at the bottom of the first housing (630) and may be an exterior case of the electronic device (600). The back cover (690) may be formed by a polymer, coated or colored glass, ceramic, metal (e.g., aluminum, stainless steel (STS), or magnesium), or a combination of at least two of the above materials.

[0101] FIG. 10 is a drawing showing a fixed section and a bendable section of a display according to various embodiments of the present disclosure. FIG. 11 and FIG. 12 are drawings showing a display supported by a bendable member according to various embodiments of the present disclosure.

[0102] Referring to FIGS. 10 to 12, the movement of the bendable member (620) is guided by a guide rail (650), so that the bendable member (620) can move in the x-axis direction and the -x-axis direction. A display (610) attached to the bendable member (620) can be expanded or contracted by the movement of the bendable member (620).

[0103] In the electronic device (600) according to various embodiments of the present disclosure, in a first state (e.g., closed state), only the fixed section (610a) of the display (610) may be visually exposed to the outside. In a second state of the electronic device (600) (e.g., open state), the bendable section (610b) of the display (610) may be moved in the x-axis direction via the bending section (601), thereby allowing the fixed section (610a) and the bendable section (610b) to be visually exposed to the outside. A plurality of multi-bars of the bendable member (620) (e.g., multi-bars (622) of FIG. 8) may support the display (610) in at least a portion of the bendable section (610b) and the fixed section (610a), thereby reducing the display (610) from lifting in the z-axis direction or sagging in the -z-axis direction.

[0104] FIG. 13 is a drawing showing a bending plate (1320) disposed between a display (610) and a multi-bar (1310) of a bendable member according to various embodiments of the present disclosure. FIG. 14 is a drawing showing a bending plate according to various embodiments of the present disclosure.

[0105] Referring to FIGS. 13 and 14, a bending plate (1320) may be placed between the display (610) and the multi-bars (1310) of the bendable member.

[0106] According to one embodiment, the bending plate (1320) may be placed in a bendable section (e.g., the bendable section (610b) of FIG. 10) that is positioned to be visible from the outside in a slide-out state among the lower parts of the display (610).

[0107] According to one embodiment, the upper surface of the bending plate (1320) can be attached to the lower surface of the display (610) via a first adhesive member (1330) (e.g., a first adhesive tape). For example, the first adhesive member (1330) can be attached to the entire upper surface of the bending plate (1320). The lower surface of the bending plate (1320) can be attached to the upper surface of the multi-bar (1310) (e.g., the upper surface (1311) of FIG. 15a) via a separate second adhesive member (e.g., a second adhesive tape). For example, the second adhesive member (1340) can be attached to the entire lower surface of the bending plate (1320).

[0108] According to one embodiment, the lower surface of the bending plate (1320) can be attached to the upper surface of the multi-bar (1310) (e.g., the upper surface (1311) of FIG. 15a) through a welding method. According to one embodiment, the lower surface of the bending plate (1320) can be attached to the upper surface of the multi-bar (1310) (e.g., the upper surface (1311) of FIG. 15a) through a bonding method.

[0109] According to one embodiment, the bending plate (1320) may be formed from a metal material or a rubber material (e.g., urethane, LSR (liquid silicone rubbers)). Not limited thereto, the bending plate (1320) may be formed from a material that flexibly changes with compressive and tensile stresses and has little change in thickness when compressive and tensile stresses are applied.

[0110] According to one embodiment, the bending plate (1320) may include a support plate (1322) positioned to correspond to the upper surface of the multi-bar (1310) and an extension section (1324) (e.g., an interlocking section) positioned to correspond to the gap (d) formed between the multi-bars (1310). At least a portion of the support plate (1322) may be uniformly cut to form the extension section (1324). When the bendable section of the display (610) (e.g., the bendable section (610b) of FIG. 10) moves in the x-axis direction via the bending portion (601), a compressive force is applied, and the gap (d) between the multi-bars (1310) is narrowed. When the gap (d) between the multi-bars (1310) is narrowed, interference between the multi-bars (1310) may occur, and local tensile stress may occur in the section between the multi-bars (1310). The bendable member can be flexibly bent by the expansion section (1324), thereby reducing interference between the multi-bars (1310) caused by compressive and tensile stresses applied to the multi-bars (1310), and reducing lifting of the bending plate (1320). For example, if the bending plate (1320) is not placed between the display (610) and the plurality of multi-bars (1310), the gap between the multi-bars (1310) at the bending section is narrowed, and as a result, compressive force is applied to the display (610), causing lifting to occur in at least a portion of the display (610). A bending plate (1320) including a support plate (1322) and an extension section (1324) (e.g., an interlocking section) is placed between a display (610) and a plurality of multi-bars (1310), thereby reducing the compressive force that can be applied to the display (610) even if the gap between the multi-bars (1310) narrows at the bending section, so as to prevent defects such as lifting or deformation of the display (610).

[0111] FIG. 15a is a drawing showing a multi-bar of a bendable member according to various embodiments of the present disclosure. FIG. 15b is a drawing showing avoidance of interference between multi-bars during curved movement of the bendable member. FIG. 15c is a drawing showing the shape of a multi-bar for avoiding interference between multi-bars during curved movement of the bendable member.

[0112] Referring to FIGS. 15a through 15c, the multi-bars (1310) can be arranged at regular intervals (e.g., interval (d) in FIG. 14) so ​​that interference between the multi-bars (1310) does not occur in the bendable section (e.g., bendable section (610b) of FIG. 10) of the display (610). By forming regular intervals (d) between the multi-bars (1310), the display (610) can implement a curved shape in the bendable section (e.g., bendable section (610b) of FIG. 10).

[0113] According to one embodiment, a portion with a certain gap (d) between the multi-bars (1310) may be subjected to compressive and tensile stresses, and an extension section (e.g., the extension section (1324) of FIG. 13 and FIG. 14) of a bending plate (e.g., the bending plate (1320) of FIG. 14) may be positioned to correspond to the gap (d). In the bendable section (e.g., the bendable section (610b) of FIG. 10), the gap between the multi-bars (1310) is narrowed, and the compressive force that can be applied to the display (610) can be reduced by the extension section (e.g., the interlocking section) (e.g., the extension section (1324) of FIG. 13 and FIG. 14).

[0114] According to one embodiment, in order to realize the curved shape of the display (610) in a bendable section (e.g., bendable section (610b) of FIG. 10), the multi-bar (1310) may have a first width (w1) of the upper surface (1311) and a second width (w2) of the lower surface (1312) formed differently. The first width (w1) of the upper surface of the multi-bar (1310) may be formed wider than the second width (w2) of the lower surface. A side surface (1313) may be disposed between the upper surface (1311) and the lower surface (1312) of the multi-bar (1310), and the side surface (1313) may be formed to be inclined at a certain angle (A). As an example, the side surface (1313) may be formed to form an angle of 100 to 110° so that the upper surface (1311) becomes wider than the lower surface (1312).

[0115] According to one embodiment, in order to avoid or reduce interference between the multi-bars (1310) during the curved movement of the multi-bars (1310), the edge (1311a) of the upper surface (1311) of the multi-bar (1310) may be formed to have a certain curvature (e.g., 0.2R) (e.g., rounded shape). Additionally, the edge (1312a) of the lower surface (1312) of the multi-bar (1310) may also be formed to have a certain curvature (e.g., 0.2R) (e.g., rounded shape).

[0117] Referring to FIGS. 16 through 17c, a bending plate (1620) may be positioned between the multi-bars (1610) of a bendable member (e.g., the bendable member (620) of FIG. 8) and the display (610). The support plate (1622) of the bending plate (1620) may be positioned between the upper surface of the multi-bar (1610) and the display (610). The extension section (1624) (e.g., the interlocking section) of the bending plate (1620) may be positioned to correspond to the gap (d) between the multi-bars (1610). For example, at least the multi-bars (1610) may be positioned to overlap with the support plate (1622) of the bending plate (1620) (e.g., positioned vertically with respect to the z-axis direction of FIGS. 2, 3, and 6 so as to overlap). At least a portion of the multi-bars (1610) may be arranged to overlap with at least a portion of the extension section (1624) of the bending plate (1620). For example, the spacing between the multi-bars (1310) is narrowed and a bend is formed in the bending section (e.g., the bending section (601) of FIG. 10), and the bendable member (e.g., the bendable member (620) of FIG. 8) and the display (610) can be flexibly bent by the extension section (1624) of the bending plate (1620) in the bendable section (e.g., the bendable section (610b) of FIG. 10) to form a curved section.

[0118] According to one embodiment, a first adhesive member (1630) (e.g., adhesive tape) may be disposed on the upper surface of the bending plate (1620).

[0119] According to one embodiment, a plurality of second adhesive members (1640) (e.g., adhesive tape) may be disposed on the lower surface of the bending plate (1620). The plurality of second adhesive members (1640) may be disposed on a portion of the lower surface of the bending plate (1620) corresponding to the support plate (1622) (e.g., a portion corresponding to the upper surface of the multi-bar (1610)). The bending plate (1620) may be attached to the upper surface of the multi-bar (1610) by means of the second adhesive members (1640).
