For example, a hinge structure (260) within the hinge cover (265) may be positioned between a first housing part (210) and a second housing part (220) of the electronic device (201) to allow the electronic device (201) to be bent, curved, or folded. For example, the first housing part (210) may be connected to the second housing part (220) through a hinge structure (260) positioned within the hinge cover (265) and may be rotated along a folding axis (237).
[0075] In one embodiment, the electronic device (201) can be folded so that the first housing part (210) and the second housing part (220) face each other by rotating about a folding axis (237). In one embodiment, the electronic device (201) can be folded so that the first housing part (210) and the second housing part (220) overlap or overlap each other. The first housing part (210) and the second housing part (220) rotatable relative to the first housing part (210) can be described as a foldable housing of the electronic device (201). The foldable housing of the electronic device (201) may further include a hinge structure (260) that enables mutual rotation of the first housing part (210) and the second housing part (220).
[0076] The hinge structure (260) may include a hinge module and hinge plates (266, 267). The hinge module may include a hinge gear (262, 263) that makes the first housing part (210) and the second housing part (220) pivotable.
[0077] The first housing part (210) may include a first bracket (270), and the second housing part (220) may include a second bracket (280). The first bracket (270) may be partially covered by the first side wall (213), and the second bracket (280) may be partially covered by the second side wall (223). The first bracket (270) may be formed integrally with the first side wall (213), and the second bracket (280) may be formed integrally with the second side wall (223). According to one embodiment, the first bracket (270) may be formed separately from the first side wall (213), and the second bracket (280) may be formed separately from the second side wall (223). The first side wall (213) and the second side wall (223) may be formed of a metal material, a non-metal material, or a combination thereof.
[0078] For example, the first sidewall (213) may be configured to function as at least part of the antenna of the electronic device (201). For example, the conductive portion included in the first sidewall (213) may be used as the antenna radiator of the electronic device (201). For example, the second sidewall (223) may be configured to function as at least part of the antenna of the electronic device (201). For example, the second sidewall (223) may include a conductive portion (228) and a non-conductive portion (229). The conductive portion (228) of the second sidewall (223) may be used as the antenna radiator of the electronic device (201).
[0079] One side of the first bracket (270) is coupled to the rear plate (290), and the other side of the first bracket (270) can be coupled to the flexible display (230). One side of the second bracket (280) is coupled to the display (235), and the other side of the second bracket (280) can be coupled to the flexible display (230).
[0080] A printed circuit board (250) and a battery may be disposed in the space between the surface formed by the first bracket (270) and the second bracket (280) and the surface formed by the display (235) and the rear plate (290). The printed circuit board (250) may be separated so as to be disposed on the first bracket (270) of the first housing part (210) and the second bracket (280) of the second housing part (220), respectively. Components for implementing various functions of the electronic device (201) may be disposed on the printed circuit board (250).
[0081] According to one embodiment, the first printed circuit board (251) may have components for implementing the overall function of the electronic device (201) placed thereon, and the second printed circuit board (252) may have electronic components for implementing some function of the first printed circuit board (251) placed thereon, or components for driving a display panel placed on the fourth side (222) placed thereon. The first printed circuit board (251) and the second printed circuit board (252) may be electrically connected by a flexible printed circuit board (240).
[0082] The battery (255) may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell as a device for supplying power to at least one component of the electronic device (201). At least a portion of the battery (255) may be disposed substantially coplanar with the printed circuit board (250). The surface formed substantially coplanar with the printed circuit board (250) and the battery (255) may be disposed on one side of the first bracket (270) and the second bracket (280) (e.g., the side facing the second side (212) and the fourth side (222) or the side facing the display panel and the rear plate (290). For example, a flexible display (230) may be placed on the first surface (211) and the third surface (221), and a printed circuit board (250) and a battery (255) may be placed on the second surface (212) and the fourth surface (222) facing the surface where the flexible display (230) is placed.
[0083] In one embodiment, the antenna (285) may be positioned between the rear plate (290) and the battery (255). The antenna (285) may include, for example, a near field communication (NFC) antenna, a wireless charging antenna, and / or a magnetic secure transmission (MST) antenna. The antenna (285) may, for example, communicate near-field with an external device or wirelessly transmit and receive power required for charging.
[0084] In the following, redundant descriptions of configurations having the same reference numerals as the configurations described above may not be repeated. Additionally, in the description of a specific drawing, reference numerals of other drawings may be referenced.
[0085] FIG. 3a shows an electronic device in an unfolded state according to one embodiment.
[0086] FIG. 3b shows an electronic device in a folded state according to one embodiment.
[0087] FIG. 3a may be a cross-sectional view of the electronic device (201) of FIG. 2a cut in a direction perpendicular to the folding axis (237) (e.g., X-axis). The Z-axis shown in FIG. 3a and other drawings may be an axis substantially perpendicular to the display (330) of the electronic device (201) in an unfolded state.
[0088] Referring to FIG. 3a, an electronic device (201) according to one embodiment may include a flexible display (330) (hereinafter, display (330) (e.g., flexible display (230)), a plate (390), and a hinge assembly (360) (e.g., hinge structure (260)).
[0089] The display (330) may include a first part (331), a second part (332) spaced apart from the first part (331), and a third part (333) extending from the first part (331) to the second part (332). The first display area (231) (Fig. 2a) of the display (330) may be included in the first part (331) of the display (330) or defined by the first part (331) of the display (330). The second display area (232) (Fig. 2a) of the display (330) may be included in the second part (332) of the display (330) or defined by the second part (332) of the display (330). The third display area (233) (Fig. 2a) of the display (330) may be included in the third part (333) of the display (330) or defined by the third part (333) of the display (330).
[0090] As illustrated in FIG. 3a, the third portion (333) of the display (330) may be unfolded (or substantially flat) when the electronic device (201) is unfolded. Alternatively, as illustrated in FIG. 3b, at least a portion of the third portion (333) of the display (330) may be bent when the electronic device (201) is folded. The first portion (331) and the second portion (332) of the display (330) may remain substantially flat regardless of whether the electronic device (201) is folded or unfolded.
[0091] Referring again to FIG. 3a, the plate (390) may be positioned below the display (330) (e.g., in the -Z direction). The plate (390) may be attached to at least a portion of the back surface of the display (330). The plate (390) may be formed to have a predetermined rigidity to support the display (330) and to protect the display (330). For example, the plate (390) may be formed of metal, though not limited thereto. The plate (390) may be described as being included in the display (330).
[0092] The plate (390) may include a first part (391), a second part (392) spaced apart from the first part (391), and a third part (393) extending from the first part (391) to the second part (392).
[0093] A first part (391) of the plate (390) may be positioned below (e.g., in the -Z direction) the first part (331) of the display (330) to support the first part (331) of the display (330). A first part (391) of the plate (390) may be attached to the first part (331) of the display (330). A first part (391) of the plate (390) may be positioned on (e.g., in the +Z direction) the first bracket (270) (Fig. 2c) of the first housing part (210) (Fig. 2c) of the electronic device (201).
[0094] The second part (392) of the plate (390) may be positioned below the second part (332) of the display (330) (e.g., in the -Z direction) to support the second part (332) of the display (330). The second part (392) of the plate (390) may be attached to the second part (332) of the display (330). The second part (392) of the plate (390) may be positioned on the second bracket (280) (Fig. 2c) of the second housing part (220) (Fig. 2c) of the electronic device (201) (e.g., in the +Z direction).
[0095] The third part (393) of the plate (390) may be positioned below the third part (333) of the display (330) (e.g., in the -Z direction). For example, the third part (393) of the plate (390) may overlap at least partially with the third part (333) of the display (330) (e.g., in the Z axis).
[0096] Referring to FIG. 3b, the third portion (393) of the plate (390) can be bent when the electronic device (201) is folded. For example, the third portion (393) of the plate (390) can be bent together with the third portion (333) of the display (330) when the electronic device (201) is folded. The third portion (393) of the plate (390) can be described as a bendable portion.
[0097] In the third portion (393) of the plate (390), a plurality of slits (396) (or openings) may be formed to provide flexibility to the third portion (393) of the plate (390). For example, the third portion (393) of the plate (390) may include an area where a plurality of slits (396) are formed. For example, the plate (390) may include recesses in addition to the plurality of slits (396). Alternatively, the plurality of slits (396) may be formed in the form of recesses that do not completely penetrate the plate (390). That is, the plate (390) may include an area where a plurality of slits (396) are formed and / or an area where recesses are formed. For example, without limitation, each of the plurality of slits (396) may have an elongated shape in a direction substantially parallel to the folding axis (237) (Fig. 2a) of the electronic device (201). A third portion (393) of the plate (390) may include a pattern (397) defined by the plurality of slits (396). For example, without limitation, the pattern (397) may be a lattice pattern formed by arranging the plurality of slits (396) in a brick pattern. For example, the plurality of slits (396) may be aligned in a line in a direction parallel to the folding axis (237) but arranged offset in a direction perpendicular to the folding axis (237). As another example, the pattern (397) may be a stripe pattern in which a plurality of slits (396) are each elongated in a direction parallel to the folding axis (237) and arranged at regular intervals in a direction perpendicular to the folding axis (237) (e.g., plate (490) of FIG. 5B). The plate (390) may be described as a support plate or a lattice plate.
[0098] Referring again to FIG. 3a, the third portion (393) of the plate (390) can be unfolded (or substantially flat) when the electronic device (201) is unfolded. The first portion (391) and the second portion (392) of the plate (390) can remain substantially flat regardless of whether the electronic device (201) is unfolded or folded.
[0099] The hinge structure (360) may include a first hinge plate (361) (e.g., first hinge plate (266)), a second hinge plate (362) (e.g., second hinge plate (267)), and a center plate (363). The first hinge plate (361) and the second hinge plate (362) may be described as a first wing plate and a second wing plate, respectively. The center plate (363) may have a bar shape extending parallel to the folding axis (237) (Fig. 2a) of the electronic device (201). In this respect, the center plate (363) may be described as a center bar (363).
[0100] The first hinge plate (361) and the second hinge plate (362) may be positioned below the plate (390) (e.g., in the -Z direction). The first hinge plate (361) and the second hinge plate (362) may be attached to the plate (390). For example, the first hinge plate (361) may be attached to a first portion (391) of the plate (390) and / or a first area of a third portion (393) of the plate (390) adjacent to the first portion (391) through an adhesive material (366). For example, the second hinge plate (362) may be attached to the second part (392) of the plate (390) and / or the second region (e.g., opposite to the first region) of the third part (393) of the hinge plate (390) adjacent to the second part (392) through an adhesive material (367).
[0101] The center plate (363) may be positioned below the plate (390) (e.g., in the -Z direction). For example, the center plate (363) may be positioned below the third part (393) of the plate (390) (e.g., in the -Z direction). When the electronic device (201) is unfolded, the center plate (363) may be positioned between the first hinge plate (361) and the second hinge plate (362).
[0102] Referring to FIG. 3b, when the electronic device (201) is folded, the first hinge plate (361) and the second hinge plate (362) may each rotate in the direction in which the electronic device (201) is folded. For example, when the electronic device (201) is folded, the first hinge plate (361) and the second hinge plate (362) may each rotate toward each other. The center plate (363) may not move regardless of whether the electronic device (201) is folded or unfolded.
[0103] When the electronic device (201) is folded, the third part (333) of the display (330) and the third part (393) of the plate (390) can be bent within the space defined by the first hinge plate (361), the second hinge plate (362), and the center plate (363). For example, when the electronic device (201) is folded, the first hinge plate (361), the second hinge plate (362), and the center plate (363) can bend the third part (333) of the display (330) and the third part (393) of the plate (390) into a specified shape.
[0104] In FIG. 3b, an example is shown in which the third part (333) of the display (330) and the third part (393) of the plate (390) are bent into a teardrop shape by the first hinge plate (361), the second hinge plate (362), and the center plate (363), but is not limited thereto. For example, when the electronic device (201) is folded, the third part (333) of the display (330) and the third part (393) of the plate (390) can be bent into a U shape by the hinge structure (360).
[0105] The center plate (363) can support the third part (393) of the plate (390) when the electronic device (201) is folded. When the electronic device (201) is folded, the center plate (363) can press the third part (393) of the plate (390) (e.g., in direction (A)). When the electronic device (201) is folded, the area of the third part (393) of the plate (390) that is pressed by the center plate (363) can be deformed along the surface shape of the third part (393) of the plate (390). For example, the center plate (363) may include a recess formed as a curved surface that contacts the third part (393) of the plate (390) when the electronic device (201) is folded.
[0106] When the electronic device (201) is folded, the third part (393) of the plate (390) can be pressed by the center plate (363), and the third part (393) of the plate (390) can press the third part (333) of the display (330). Accordingly, the third part (333) of the display (330) can be pressed by the pattern (397) of the third part (393) of the plate (390). As the third part (333) of the display (330) is pressed by the pattern (397) of the plate (390), at least one of the layers included in the display (330) can be plastically deformed into the shape of the pattern (397). The mark resulting from this plastic deformation can be seen from outside the display (330). In the drawings below, a stack structure of a display (330) capable of reducing and / or preventing the aforementioned problems is illustrated.
[0107] FIG. 4 is a cross-sectional view showing a layer structure of a display according to one embodiment. FIG. 4 may be a cross-sectional view of the electronic device (201) of FIG. 2a cut in a direction perpendicular to the folding axis (237) (e.g., X-axis).
[0108] Referring to FIG. 4, a display (330) according to one embodiment may include a plurality of layers. For example, the display (330) may include a flexible display panel (430) (hereinafter, display panel (430)), a window (420) placed on the display panel (430) (e.g., + Z direction), a first layer (450) placed below the display panel (430) (e.g., - Z direction), a second layer (470) placed below the first layer (450) (e.g., - Z direction), and a plate (490) placed below the second layer (470) (e.g., - Z direction) (e.g., plate (390)). The plate (490) may include a first portion (491) (e.g., first portion (391)), a second portion (492) (e.g., second portion (392)), and a bendable portion (493) (e.g., third portion (393)) having a plurality of slits (496) (e.g., slits (396)) formed therein. The display (330) may further include a protective layer (410) disposed on the window (420) (e.g., in the +Z direction).
[0109] Each of the protective layer (410), window (420), display panel (430), first layer (450), second layer (470), and plate (490) may include a front side (e.g., facing the +Z direction) and a back side opposite to the front side (e.g., facing the -Z direction). For example, at least a portion of the front side of the protective layer (410) may be visually exposed to the outside of the electronic device (201).
[0110] According to one embodiment, the display (330) may include adhesive layers for mutually attaching the plurality of layers included in the display (330). For example, the display (330) may include an adhesive layer (415) for attaching the back surface of the protective layer (410) to the front surface of the window (420), an adhesive layer (425) for attaching the back surface of the window (420) to the front surface of the display panel (430), an adhesive layer (440) for attaching the back surface of the display panel (430) to the front surface of the first layer (450), a first adhesive layer (460) for attaching the back surface of the first layer (450) to the front surface of the second layer (470), and a second adhesive layer (480) for attaching the back surface of the second layer (470) to the front surface of the plate (490). The adhesive layers (415, 425, 440, 460, and 480) may include a pressure-sensitive adhesive (PSA).
[0111] The display panel (430) may be configured to emit light to provide visual information. For example, the display panel (430) may include a flexible substrate, a circuit layer comprising thin film transistors (TFTs) formed on the flexible substrate, a light-emitting layer comprising light-emitting diodes (LEDs) or organic LEDs (OLEDs) formed on the circuit layer and configured to emit light by being controlled by the TFTs, and an encapsulation layer formed on the light-emitting layer. Additionally, the display panel (430) may include a touch sensor layer used to identify a user's touch on the protective layer (410). Light emitted from the display panel (430) may be transmitted to the outside through an adhesive layer (425), a window (420), an adhesive layer (415), and a protective layer (410).
[0112] The window (420) can be formed to be substantially transparent and flexible. The window (420) can protect the display panel (430) by covering the display panel (430). The window (420) can be formed of, for example, glass (e.g., UTG (ultra thin glass)) and / or plastic.
[0113] The protective layer (410) can protect the window (420) from external impact or scratches. The protective layer (410) can be formed of plastic, for example, PET (Polyethylene Terephthalate), but is not limited to plastic.
[0114] The first layer (450) may be placed between the display panel (430) and the plate (490). For example, the first layer (450) may be placed between the display panel (430) and the second layer (470). The first layer (450) may be formed of, for example, a polymer material. The first layer (450) may be configured to block light. The first layer (450) may be configured to block light emitted downward (e.g., in the -Z direction) from the display panel (430). For example, the first layer (450) may include a coating layer configured to block light. For example, the first layer (450) may include a black coated film (e.g., a PET (polyethylene terephthalate) film).
[0115] The second layer (470) may be disposed between the display panel (430) and the plate (490). For example, the second layer (470) may be disposed between the first layer (450) and the plate (490). The second layer (470) may overlap at least partially with the bendable portion (493) of the plate (490). For example, the second layer (470) may overlap at least one of the plurality of slits (496) formed in the bendable portion (493) of the plate (490). For example, the second layer (470) may cover at least one of the plurality of slits (496) formed in the bendable portion (493) of the plate (490). The second layer (470) may be formed of plastic, not limited to, for example, polyimide, and / or polyethylene terephthalate (PET).
[0116] A second layer (470) may be attached to the front surface of the plate (490) to flatten the surface of the plate (490). By attaching the plate (490) to the display panel (430) (or the first layer (450)) through the second layer (470), the adhesion between the plate (490) and the display panel (430) (or the first layer (450)) may be improved. Additionally, by attaching the plate (490) to the display panel (430) (or the first layer (450)) through the second layer (470), the surface characteristics of the display (330) may be improved (for example, the uneven surface characteristics of the plate (490) being visible through the display panel (490) may be reduced and / or prevented).
[0117] Additionally, the second layer (470) is positioned between the display panel (430) and the plate (490), thereby mitigating the impact that may be applied to the display panel (430) by the plate (490), which has relatively strong rigidity, in the event of an external impact such as a fall.
[0118] Additionally, the second layer (470) can reduce and / or block the inflow of foreign substances through the plurality of slits (496) by covering the plurality of slits (496) of the plate (490). Additionally, the second layer (470) can reduce and / or prevent foreign substances stuck in the plurality of slits (496) or already entered through the plurality of slits (496) from being visible from the outside through the display (330) by covering the plurality of slits (496) of the plate (490).
[0119] Each of the plurality of layers included in the display (330) may include a first portion corresponding to or at least partially included in a first portion (331) of the display (330). Additionally, each of the plurality of layers included in the display (330) may include a second portion corresponding to or at least partially included in a second portion (332) of the display (330). Additionally, each of the plurality of layers included in the display (330) may include a third portion corresponding to or at least partially included in a third portion (333) of the display (330).
[0120] For example, each of the protective layer (410), window (420), display panel (430), first layer (450), second layer (470), and plate (490) may include the first part corresponding to or at least partially included in the first part (331) of the display (330), the second part corresponding to or at least partially included in the second part (332) of the display (330), and the third part corresponding to or at least partially included in the third part (333) of the display (330).
[0121] For example, the second layer (470) may include a first part (471) corresponding to or at least partially included in the first part (331) of the display (330), a second part (472) corresponding to or at least partially included in the second part (332) of the display (330), and a third part (473) corresponding to or at least partially included in the third part (333) of the display (330). For example, the first part (471) of the second layer (470) may be spaced apart from the second part (472) of the second layer (470). For example, the third part (473) of the second layer (470) may extend from the first part (471) of the second layer (470) to the second part (472).
[0122] For example, the plate (490) may include a first part (491) corresponding to or at least partially included in a first part (331) of the display (330), a second part (492) corresponding to or at least partially included in a second part (332) of the display (330), and a third part (493) corresponding to or at least partially included in a third part (333) of the display (330).
[0123] The first adhesive layer (460) may be disposed between the first layer (450) and the second layer (470). The first adhesive layer (460) may include a first portion (461) and a second portion (462) spaced apart from the first portion (461). For example, the first portion (461) of the first adhesive layer (460) may be spaced apart from the second portion (462) of the first adhesive layer (460) by a first gap (g1). The first width of the first gap (g1) may be smaller than the width of the bendable portion (493) of the plate (490). The first width of the first gap (g1) and the width of the bendable portion (493) may be lengths along a direction perpendicular to the folding axis (237) (e.g., the X-axis).
[0124] A first portion (471) of the second layer (470) can be attached to the first layer (450) (e.g., the first portion of the first layer (450)) through the first portion (461) of the first adhesive layer (460). A second portion (472) of the second layer (470) can be attached to the first layer (450) (e.g., the second portion of the first layer (450)) through the second portion (462) of the first adhesive layer (460). A third portion (473) of the second layer (470) can face the first layer (450) (e.g., the third portion of the first layer (450)) through the first gap (g1). A third portion (473) of the second layer (470) can overlap at least partially with the bendable portion (493) of the plate (490). For example, the third part (473) of the second layer (470) may overlap with at least one of the plurality of slits (496) formed in the bendable part (493) of the plate (490).
[0125] The second adhesive layer (480) may be disposed between the second layer (470) and the plate (490). The second adhesive layer (480) may include a first portion (481) and a second portion (482) spaced apart from the first portion (481). For example, the first portion (481) of the second adhesive layer (480) may be spaced apart from the second portion (482) of the second adhesive layer (480) by a second gap (g2).
[0126] The first width of the first gap (g1) may differ from the second width of the second gap (g2). For example, the first width of the first gap (g1) may be smaller than the second width of the second gap (g2), but is not limited thereto. Alternatively, the first width of the first gap (g1) may be substantially the same as the second width of the second gap (g2). The first width of the first gap (g1) and the second width of the second gap (g2) may be lengths along a direction perpendicular to the folding axis (237) (e.g., X-axis) when the electronic device (201) is unfolded.
[0127] A first portion (491) of the plate (490) can be attached to a second layer (470) (e.g., first portion (471)) through a first portion (481) of the second adhesive layer (480). A second portion (492) of the plate (490) can be attached to a second layer (470) (e.g., second portion (472)) through a second portion (482) of the second adhesive layer (480). A bendable portion (493) of the plate (490) can face a second layer (470) (e.g., third portion (473)) through a second gap (g2) of the second adhesive layer (480).
[0128] When the electronic device (201) is folded, the bendable portion (493) of the plate (490) can press against the third portion (473) of the second layer (470). In a comparative example, the first adhesive layer (460) may further include a third portion that attaches the third portion (473) of the second layer (470) to the first layer (450) (e.g., filling the first gap (g1)). When the electronic device (201) is folded, the third portion (473) of the second layer (470) can be plastically deformed by being pressed by the bendable portion (493) of the plate (490). In this case, a mark corresponding to the pattern (397) (Fig. 3b) of the bendable portion (493) of the plate (490), defined by a plurality of slits (496), can be formed on the third portion (473) of the second layer (470). Since the third portion (473) of the second layer (470) is in contact with the third portion of the first adhesive layer (460) and the third portion of the first adhesive layer (460) is in contact with the first layer (450), the mark formed on the third portion (473) of the second layer (470) can be seen from outside the display (330). In addition, since the first layer (450) can be pressed from the bendable portion (493) of the plate (490) through the third portion (473) of the second layer (470) and the third portion of the first adhesive layer (460), the first layer (450) can be plastically deformed even if the second layer (470) is not plastically deformed. In this case, a mark corresponding to the pattern (397) (Fig. 3b) of the bendable portion (493) of the plate (490) can be formed on the first layer (450). The mark formed on the first layer (450) can be seen from outside the display (330).
[0129] In one embodiment, the third portion (473) of the second layer (470) may be spaced apart from the first layer (450) through a first gap (g1) so that the bendable portion (493) of the plate (490) does not press the first layer (450) (e.g., the third portion of the first layer (450)) through the third portion (473) of the second layer (470). Accordingly, plastic deformation of the first layer (450) by the bendable portion (493) of the plate (490) may be reduced and / or prevented. Additionally, even if the third portion (473) of the second layer (470) is plastically deformed, the visibility of the mark formed on the third portion (473) of the second layer (470) from outside the display (330) may be reduced and / or prevented because it is physically spaced apart from the first layer (450).
[0130] FIG. 5a is a cross-sectional view showing a layer structure of a display according to one embodiment. FIG. 5b is a plan view showing a plate having a stripe pattern according to one embodiment.
[0131] FIG. 5a may be a cross-sectional view of the electronic device (201) of FIG. 2a cut in a direction perpendicular to the folding axis (237) (e.g., X-axis).
[0132] Referring to FIG. 5a, according to one embodiment, the second adhesive layer (480) may further include a third portion (583). The first portion (481), the second portion (482), and the third portion (583) of the second adhesive layer (480) may be formed integrally. Whether the second adhesive layer (480) is configured as a separate type (e.g., the second adhesive layer (480) of FIG. 4) or as an integral type (e.g., the second adhesive layer (480) of FIG. 5a) may depend on the pattern of the bendable portion (493) of the plate (490) below the second adhesive layer (480). For example, if the plate (490) is composed of physically separated multiple pieces by opening at least a portion of the slits (496) defining the pattern of the bendable portion (493) of the plate (490) to both edges of the plate (490), the second adhesive layer (480) attached to the plate (490) may be formed integrally to maintain the shape of the plate (490).
[0133] The third portion (583) of the second adhesive layer (480) may be positioned between the bendable portion (493) of the plate (490) and the third portion (473) of the second layer (470). The third portion (583) of the second adhesive layer (480) may attach the bendable portion (493) of the plate (490) to the second layer (470) (e.g., the third portion (473)).
[0134] Referring to FIG. 5b, the bendable portion (493) of the plate (490) may include a plurality of bars (597) forming a stripe pattern. For example, the plurality of bars (597) may be spaced apart from each other. The plurality of bars (597) may be completely separated from each other. The plurality of bars (597) may be spaced apart from the first portion (491) and the second portion (492) of the plate (490). The plurality of bars (597) may each be elongated in a direction parallel to the folding axis (237) (e.g., Y-axis) and may be arranged to have a specified spacing in a direction perpendicular to the folding axis (237) (e.g., X-axis). For example, each of the plurality of slits defined between the plurality of bars (597) may be open to the upper side (e.g., +Y direction) and the lower side (e.g., -Y direction) of the plate (490). For example, at least some of the plurality of slits defined between the plurality of bars (597) may be closed to the upper side and the lower side of the plate (490). In this case, the bendable portion (493) of the plate (490) may include bridge portions extending between the plurality of bars (597) to close both ends of the at least some of the plurality of slits. For example, when both ends of all of the plurality of slits defined between the plurality of bars (597) are closed, the bridge portions may form the upper and lower edges of the bendable portion (493) of the plate (490).
[0135] Referring to FIG. 5a, a plurality of bars (597) can be attached to a third portion (583) of a second adhesive layer (480). A plurality of bars (597), a first portion (491) of a plate (490), and a second portion (492) of a plate (490) can be connected to each other through the second adhesive layer (480).
[0136] FIG. 6 is a cross-sectional view showing a layer structure of a display according to one embodiment. FIG. 6 may be a cross-sectional view of the electronic device (201) of FIG. 2a cut in a direction perpendicular to the folding axis (237) (e.g., X-axis).
[0137] Referring to FIG. 6, the display (330) may not include the aforementioned second layer (470). In this case, the display (330) may include a second adhesive layer (680) (e.g., second adhesive layer (480)) and a third adhesive layer (640) (e.g., adhesive layer (440)). The plate (490) may be attached to the first layer (450) through the second adhesive layer (680), and the first layer (450) may be attached to the display panel (430) through the third adhesive layer (640). The second adhesive layer (680) and the third adhesive layer (640) may include a pressure-sensitive adhesive (PSA).
[0138] For example, the first layer (450) may include a first part (651) corresponding to or at least partially included in a first part (331) of the display (330), a second part (652) corresponding to or at least partially included in a third part (333) of the display (330), and a third part (653) corresponding to or at least partially included in a third part (333) of the display (330). For example, the first part (651) of the first layer (450) may be spaced apart from the second part (652) of the first layer (450). For example, the third part (653) of the first layer (450) may extend from the first part (651) of the first layer (450) to the second part (652).
[0139] The first layer (450) may be disposed between the display panel (430) and the plate (490). The first layer (450) may overlap at least partially with the bendable portion (493) of the plate (490). For example, the first layer (450) may overlap at least one of the plurality of slits (496) formed in the bendable portion (493) of the plate (490). For example, the first layer (450) may cover at least one of the plurality of slits (496) formed in the bendable portion (493) of the plate (490).
[0140] The second adhesive layer (680) may be disposed between the first layer (450) and the plate (490). The second adhesive layer (680) may include a first portion (681) and a second portion (682) spaced apart from the first portion (681). For example, the first portion (681) of the second adhesive layer (680) may be spaced apart from the second portion (682) of the second adhesive layer (680) by a second gap (g2).
[0141] A first portion (491) of the plate (490) can be attached to a first layer (450) (e.g., first portion (651)) through a first portion (681) of the second adhesive layer (680). A second portion (492) of the plate (490) can be attached to a first layer (450) (e.g., second portion (652)) through a second portion (682) of the second adhesive layer (680). A bendable portion (493) of the plate (490) can face a first layer (450) (e.g., third portion (653)) through a second gap (g2) of the second adhesive layer (680).
[0142] A third adhesive layer (640) may be disposed between the display panel (430) and the first layer (450). The third adhesive layer (640) may include a first portion (641) and a second portion (642) spaced apart from the first portion (641). For example, the first portion (641) of the third adhesive layer (640) may be spaced apart from the second portion (642) of the third adhesive layer (640) by a third gap (g3) (e.g., a first gap (g1)).
[0143] The third width of the third gap (g3) may be smaller than the width of the bendable portion (493) of the plate (490). The third width of the third gap (g3) may be a length along a direction perpendicular to the folding axis (237) (e.g., the X-axis). The third width of the third gap (g3) may be different from the second width of the second gap (g2). For example, the third width of the third gap (g3) may be smaller than the second width of the second gap (g2), but is not limited thereto. Alternatively, the third width of the third gap (g3) may be substantially the same as the second width of the second gap (g2).
[0144] A first portion (651) of the first layer (450) can be attached to the display panel (430) (e.g., the first portion of the display panel (430)) through the first portion (641) of the third adhesive layer (640). A second portion (652) of the first layer (450) can be attached to the display panel (430) (e.g., the second portion of the display panel (430)) through the second portion (642) of the third adhesive layer (640). A third portion (653) of the first layer (450) can be attached to the display panel (430) (e.g., the third portion of the display panel (430)) through the third gap (g3). By separating the first layer (450) from the display panel (430) through the third gap (g3), plastic deformation of the layer within the display (330) caused by the bendable portion (493) of the plate (490) can be reduced and / or prevented. By separating the first layer (450) from the display panel (430) through the third gap (g3), the visibility of marks caused by plastic deformation of the first layer (450) by the bendable portion (493) of the plate (490) to the outside through the display (330) can be reduced and / or prevented.
[0145] FIG. 7 is a cross-sectional view showing a layer structure of a display according to one embodiment. FIG. 7 may be a cross-sectional view of the electronic device (201) of FIG. 2a cut in a direction perpendicular to the folding axis (237) (e.g., X-axis).
[0146] Referring to FIG. 7, according to one embodiment, the second adhesive layer (680) may further include a third portion (783). The first portion (681), the second portion (682), and the third portion (783) of the second adhesive layer (680) may be formed integrally.
[0147] The third portion (783) of the second adhesive layer (680) may be positioned between the bendable portion (493) of the plate (490) and the third portion (653) of the first layer (450). The third portion (783) of the second adhesive layer (680) may attach the bendable portion (493) of the plate (490) to the first layer (450) (e.g., the third portion (653)).
[0148] A plurality of bars (597) of the plate (490) can be connected to each other through a third portion (783) of a second adhesive layer (680) attached to a bendable portion (493) of the plate (490). Additionally, a plurality of bars (597) can be connected to a first portion (491) and a second portion (492) of the plate (490) through the second adhesive layer (680).
[0149] FIGS. 8A, FIGS. 8B, and FIGS. 8C are drawings showing examples of slits in an adhesive layer according to one embodiment.
[0150] The adhesive layer (810) shown in FIGS. 8a, 8b, and 8c may be a first adhesive layer (460), a second adhesive layer (480), a second adhesive layer (680), or a third adhesive layer (640).
[0151] Referring to FIGS. 8A, 8B, and 8C, the adhesive layer (810) may include a first portion (811) and a second portion (812). The first portion (811) of the adhesive layer (810) may be the first portion (461) of the first adhesive layer (460), the first portion (481) of the second adhesive layer (480), the first portion (681) of the second adhesive layer (680), or the first portion (641) of the third adhesive layer (640). The second portion (812) of the adhesive layer (810) may be the second portion (462) of the first adhesive layer (460), the second portion (482) of the second adhesive layer (480), the second portion (682) of the second adhesive layer (680), or the second portion (642) of the third adhesive layer (640).
[0152] Referring to FIG. 8a, the first portion (811) and the second portion (812) of the adhesive layer (810) can be completely separated. Between the first portion (811) and the second portion (812), a slit (820) substantially parallel to the folding axis (237) (e.g., Y-axis) of the electronic device (201) can be formed. The slit (820) can be opened upward (e.g., +Y direction) and downward (e.g., -Y direction) of the adhesive layer (810). The slit (820) can define, for example, a first gap (g1) of the first adhesive layer (460), a second gap (g2) of the second adhesive layer (480), a second gap (g2) of the second adhesive layer (680), or a third gap (g3) of the third adhesive layer (640).
[0153] The bendable portion (493) of the plate (490) may include one or more portions protruding from the adhesive layer (810). For example, the bendable portion (493) of the plate (490) may include portions (895) (e.g., portion (1595) of FIG. 15a) protruding from the top of the adhesive layer (810) (e.g., the edge of the adhesive layer (810) facing the +Y direction) and the bottom of the adhesive layer (810) (e.g., the edge of the adhesive layer (810) facing the -Y direction), respectively.
[0154] Referring to FIG. 8b, a slit (822) may be formed in the adhesive layer (810). The slit (822) may be located in the center of the adhesive layer (810). The adhesive layer (810) may include a first connecting portion (813) and a second connecting portion (814). The first connecting portion (813) may extend from a first area of the first part (811) to a first area of the second part (812) facing the first area of the first part (811). The second connecting portion (814) may extend from a second area of the first part (811) to a second area of the second part (812) facing the second area of the first part (811). The first part (811), the second part (812), the first connecting part (813) and the second connecting part (814) can define the circumference of the slit (822).
[0155] The slit (822) can define, for example, a first gap (g1) of the first adhesive layer (460), a second gap (g2) of the second adhesive layer (480), a second gap (g2) of the second adhesive layer (680), or a third gap (g3) of the third adhesive layer (640).
[0156] The first connecting portion (813) or the second connecting portion (814) may be the third portion (583) of the second adhesive layer (480) or the third portion (783) of the second adhesive layer (680). For example, in FIG. 5a, the first portion (481) and the second portion (482) of the second adhesive layer (480) are shown as being connected by the third portion (583), but in other sections, a slit (822) may be formed in the second adhesive layer (480). For example, in FIG. 7, the first portion (681) and the second portion (682) of the second adhesive layer (680) are shown as being connected by the third portion (783), but in other sections, a slit (822) may be formed in the second adhesive layer (480).
[0157] Referring to FIG. 8c, a first slit (824), a second slit (826), and a third slit (828) may be formed in the adhesive layer (810). The first slit (824), the second slit (826), and the third slit (828) may be arranged parallel to the folding axis (237) (e.g., Y-axis) of the electronic device (200). The first slit (824) may be located between the second slit (826) and the third slit (828). The second slit (826) may be opened at the top of the adhesive layer (810) (e.g., in the +Y direction), and the third slit (828) may be opened at the bottom of the adhesive layer (810) (e.g., in the -Y direction).
[0158] The adhesive layer (810) may include a first connecting portion (815) extending from a third area of a first part (811) to a third area of a second part (812) to separate a first slit (824) and a second slit (826), and a second connecting portion (816) extending from a fourth area of a first part (811) to a fourth area of a second part (812) to separate a first slit (824) and a third slit (828).
[0159] At least one of the first slit (824), the second slit (826), and / or the third slit (828) may define, for example, a first gap (g1) of the first adhesive layer (460), a second gap (g2) of the second adhesive layer (480), a second gap (g2) of the second adhesive layer (680), or a third gap (g3) of the third adhesive layer (640).
[0160] The first connecting portion (815) or the second connecting portion (816) may be the third portion (583) of the second adhesive layer (480) or the third portion (783) of the second adhesive layer (680). For example, in FIG. 5a, the first portion (481) and the second portion (482) of the second adhesive layer (480) are shown as being connected by the third portion (583), but in other sections, at least one of the first slit (824), the second slit (826), and / or the third slit (828) may be formed in the second adhesive layer (480). For example, in FIG. 7, the first part (681) and the second part (682) of the second adhesive layer (680) are shown as being connected by a third part (783), but in other sections, at least one of a first slit (824), a second slit (826), and / or a third slit (828) may be formed in the second adhesive layer (480).
[0161] FIG. 9 is a cross-sectional view showing a part of the configuration of an electronic device according to one embodiment. FIG. 9 may be a cross-sectional view of the electronic device (201) of FIG. 2a cut in a direction perpendicular to the folding axis (237) (e.g., X-axis).
[0162] Referring to FIG. 9, an electronic device (201) according to one embodiment may include a first printed circuit board (951) (e.g., first printed circuit board (251)), a second printed circuit board (952) (e.g., second printed circuit board (252)), and a flexible printed circuit board (940) (e.g., flexible printed circuit board (240)).
[0163] The display (330) may include a layer (970) to which an adhesive layer (810) is attached. The layer (970) may be an example of the second layer (470) of FIG. 4, the second layer (470) of FIG. 5a, the first layer (450) of FIG. 6, or the first layer (450) of FIG. 7. A slit (920) between a first portion (811) and a second portion (812) may be formed in the adhesive layer (810). The slit (920) may be an example of slits (820, 822, 824, 826, or 828).
[0164] The flexible printed circuit board (940) may extend from the first printed circuit board (951) across the hinge structure (360) (or center plate (363)) (or the third part (333) of the display (330)) to the second printed circuit board (952).
[0165] The slit (920) of the adhesive layer (810) may overlap the flexible printed circuit board (940) (e.g., along the Z-axis). For example, the slit (920) of the adhesive layer (810) may be positioned on the flexible printed circuit board (940) and aligned with the flexible printed circuit board (940). For example, at least a portion of the slit (920) of the adhesive layer (810) may be formed on a portion (971) of the layer (970) that overlaps the flexible printed circuit board (940) and the center plate (363) (e.g., along the Z-axis).
[0166] To provide a space through which the flexible printed circuit board (940) passes, the center plate (363) may be positioned higher (e.g., in the +Z direction) than other sections that do not span the space between the first printed circuit board (951) and the second printed circuit board (952). Accordingly, when the electronic device (201) is folded, the degree to which the display (330) (e.g., layer (970)) is pressed by the center plate (363) may be greater in the section than in the other sections. By forming a slit (920) of the adhesive layer (810) on a portion (971) of the layer (970) that overlaps the flexible printed circuit board (940) and the center plate (363), the visibility of marks caused by the pattern of the plate (490) (e.g., pattern (397 and / or 597)) in the section where the display (330) is pressed more strongly can be effectively reduced and / or prevented.
[0167] FIGS. 10a, FIGS. 10b, FIGS. 10c, FIGS. 10d, FIGS. 10e, FIGS. 10f, FIGS. 10g, FIGS. 10h, FIGS. 10i, and FIGS. 10j illustrate examples of adhesive layers.
[0168] With reference to the preceding drawings, the adhesive layers (460, 480, 640, 680, 810, or 910) have been described as including sections separated by one or more slits (e.g., slits (820, 822, 824, 826, 828, or 920), but are not limited thereto, and various examples of the adhesive layers (460, 480, 640, 680, 810, 910) are described with reference to FIG. 10a, FIG. 10b, FIG. 10c, FIG. 10d, FIG. 10e, FIG. 10f, FIG. 10g, FIG. 10h, FIG. 10i, and FIG. 10j.
[0169] For example, referring to FIG. 10a, the adhesive layer (1010a) may include a first surface (1011a) and a second surface (1012a) opposite to the first surface (1011a). The first surface (1011a) may face in the +Z direction, and the second surface (1012a) may face in the -Z direction.

For example, the modulus of the material (1030d) may be different from the modulus of the adhesive layer (1010c).
[0175] For example, referring to FIG. 10e, the adhesive layer (1010e) may include a first surface (1011e) and a second surface (1012e) opposite to the first surface (1011e). The first surface (1011e) may face in the +Z direction, and the second surface (1012e) may face in the -Z direction.

The material (1030g), together with the adhesive layer (1010b), may define a first surface (1011g) of the adhesive layer (1010g). The material (1030g) may have different physical properties from the adhesive layer (1010b).

[0184] The material (1030h) may have different physical properties from the adhesive layer (1010g). For example, the modulus of the material (1030h) may be different from the modulus of the adhesive layer (1010g). The material (1030h) may be formed integrally with the material (1030g).
[0185] For example, referring to FIG. 10i, the adhesive layer (1010i) may include a first surface (1011i) and a second surface (1012i) opposite to the first surface (1011i). The first surface (1011i) may face in the +Z direction, and the second surface (1012i) may face in the -Z direction.

[0193] FIG. 11 shows a multi-foldable electronic device according to one embodiment.
[0194] FIG. 12 is a cross-sectional view of a display of a multi-foldable electronic device according to one embodiment.
[0195] Referring to FIG. 11, according to one embodiment, an electronic device (1100) (e.g., electronic device (101 or 201)) may include a first housing part (1101) (e.g., first housing part (210)), a second housing part (1102) (e.g., second housing part (220)), and a first hinge structure (1161) (e.g., hinge structure (260) or hinge assembly (360)) that rotatably connects the second housing part (1102) to the first housing part (1101).
[0196] The electronic device (1100) may also include a third housing part (1103) and a second hinge structure (1162). The third housing part (1103) may be rotatably coupled to the second housing part (1102) through the second hinge structure (1162). The first housing part (1101), the second housing part (1102), and the third housing part (1103) may be described as a foldable housing of the electronic device (1100).
[0197] Although not illustrated, the electronic device (1100) may include a flexible display (e.g., the flexible display (1130) of FIG. 12) disposed within the foldable housing of the electronic device (1100) so as to form at least a portion of the front surface of the electronic device (1100) (or the foldable housing).
[0198] The state of the electronic device (1100) illustrated in FIG. 11 may be a multi-folded state in which the first housing part (1101), the second housing part (1102), and the third housing part (1103) are folded relative to each other. In the multi-folded state, the first housing part (1101) may be placed on the third housing part (1103), and the second housing part (1102) may be placed on the first housing part (1101).
[0199] Although not illustrated, in the unfolded state of the electronic device (1100), the first housing part (1101), the second housing part (1102), and the third housing part (1103) may be placed on substantially the same plane.
[0200] Although not illustrated, in a single-folded state of the electronic device (1100), the second housing part (1102) and the third housing part (1103) can be unfolded relative to each other, and the first housing part (1101) can be folded relative to the second housing part (1102).
[0201] In the multi-folded state of the electronic device (1100), the first housing part (1101) can be folded relative to the second housing part (1102) through the first hinge structure (1161) so as to be spaced apart from the second housing part (1102) by a first distance.
[0202] In a multi-folded state of the electronic device (1100), the third housing part (1103) can be folded relative to the second housing part (1102) through the second hinge structure (1162) so as to be spaced apart from the second housing part (1102) by a second distance. When the third housing part (1103) is folded relative to the second housing part (1102), the third housing part (1103) and the second housing part (1102) are positioned, so the second distance provided through the second hinge structure (1162) may be greater than the first distance provided through the first hinge structure (1161). Accordingly, the flexible display disposed within the foldable housing of the electronic device (1100) so as to cross the first hinge structure (1161) and the second hinge structure (1162) may have different structures in the first region (R1) corresponding to the first hinge structure (1161) and the second region (R2) corresponding to the second hinge structure (1162).
[0203] For example, referring to FIG. 12, a flexible display (1130) (hereinafter, display (1130)) (e.g., display module (160) or display (330)) may include a first part (1131) (e.g., first part (331)), a second part (1132) (e.g., second part (332)), and a third part (1133) (e.g., third part (333)).
[0204] Additionally, the display (1130) may include a fourth part (1134) spaced apart from the second part (1132) and a fifth part (1135) extending from the second part (1132) to the fourth part (1134).
[0205] Referring to FIG. 12 together with FIG. 11, a first part (1131) of the display (1130) may be placed on or within a first housing part (1101), a second part (1132) of the display (1130) may be placed on or within a second housing part (1102), and a fourth part (1134) of the display (1130) may be placed on or within a third housing part (1103).
[0206] The third part (1133) of the display (1130) can be bent as the first housing part (1101) and the second housing part (1102) are folded together. The fifth part (1135) of the display (1130) can be bent as the second housing part (1102) and the third housing part (1103) are folded together.
[0207] Referring to FIG. 12, the display (1130) may include a protective layer (1210) (e.g., protective layer (410)), an adhesive layer (1215) (e.g., adhesive layer (415)), a window (1220) (e.g., window (420)), an adhesive layer (1225) (e.g., adhesive layer (425)), a display panel (1230) (e.g., display panel (430)), an adhesive layer (1240) (e.g., adhesive layer (440)), a first layer (1250) (e.g., first layer (450)), a first adhesive layer (1260) (e.g., first adhesive layer (460)), a second layer (1270) (e.g., second layer (470)), a second adhesive layer (1280) (e.g., second adhesive layer (1280)), and a plate (1290) (e.g., plate (490)).
[0208] Each of the protective layer (1210), adhesive layer (1215), window (1220), adhesive layer (1225), display panel (1230), adhesive layer (1240), first layer (1250), first adhesive layer (1260), second layer (1270), second adhesive layer (1280), and plate (1290) may include a fourth part corresponding to the fourth part (1134) of the display (1130) and a fifth part corresponding to the fifth part (1135) of the display (1130). The description of each layer of the display (1130) corresponding to the fourth part (1134) and the fifth part (1135) of the display (1130) may be applied in a substantially identical, similar, or corresponding manner to the description provided for the first part (331) and the third part (333) of the display (330) mentioned above.
[0209] The third part (1133) of the display (1130) corresponding to the first region (R1) of the first hinge structure (1161) may have a structure different from the fifth part (1135) of the display (1130) corresponding to the second region (R2) of the second hinge structure (1162).
[0210] For example, the plate (1290) may include a first area (1293) corresponding to a third part (1133) of the display (1130) and having a first pattern formed therein, and a second area (1295) corresponding to a fifth part (1135) of the display (1130) and having a second pattern formed therein. For example, the width of the first area (1293) having the first pattern formed therein and the width of the second area (1295) having the second pattern formed therein may be different from each other. For example, the width of the second area (1295) having the second pattern formed therein may be larger than the width of the first area (1293) having the first pattern formed therein. For example, the width of the first pattern itself in the first area (1293) and the width of the second pattern itself in the second area (1295) may be different from each other. For example, the width of the second pattern itself in the second region (1295) may be greater than the width of the first pattern itself in the first region (1293). For example, the width of each of the first slits defining the first pattern in the first region (1293) may be different from the width of each of the second slits defining the second pattern in the second region (1295). For example, the number of the first slits defining the first pattern in the first region (1293) may be different from the number of the second slits defining the second pattern in the second region (1295). For example, the number of the second slits defining the second pattern in the second region (1295) may be greater than the number of the first slits defining the first pattern in the first region (1293). For example, the area of the fifth part (1135) of the display (1130) corresponding to the second area (R2) may be larger than the area of the third part (1133) of the display (1130) corresponding to the first area (R1).
[0211] For example, the first adhesive layer (1260) may include a first portion (1261) (e.g., first portion (461)), a second portion (1262) (e.g., second portion (462)), and a third portion (1263). The first portion (1261) and the second portion (1262) of the first adhesive layer (1260) may be separated from each other within a first region (R1). The second portion (1262) and the third portion (1263) of the first adhesive layer (1260) may be separated from each other within a second region (R2). In the first region (R1), the first width of the first gap (S1) (e.g., first gap (g1)) formed by separating the first part (1261) and the second part (1262) of the first adhesive layer (1260) may be smaller than the second width of the second gap (S2) formed by separating the second part (1262) and the third part (1263) of the first adhesive layer (1260) in the second region (R2). The first width of the first gap (S1) and the second width of the second gap (S2) may be lengths along a direction perpendicular to the folding axis (237) of the electronic device (1100) when the electronic device (1100) is fully unfolded, for example.
[0212] Alternatively, the second part (1262) and the third part (1263) of the first adhesive layer (1260) may be connected so that the second gap (S2) is omitted from the first adhesive layer (1260) (for example, in which the fifth part (1135) of the display (1130) in a multi-folded state is bent into a U shape, but is not limited to).
[0213] With reference to FIG. 11, the electronic device (1100) is described as comprising three housing parts (1101, 1102, and 1103) and two hinge structures (1161 and 1162), but the number of housing parts and hinge structures included in the electronic device (1100) is not limited thereto. For example, the electronic device (1100) may comprise four or more housing parts and three or more hinge structures. For example, the electronic device (1100) may further comprise a fourth housing part rotatably coupled to a third housing part (1103). For example, the electronic device (1100) may further comprise a third hinge structure connecting the third housing part (1103) and the fourth housing part. For example, the fourth housing part may be located below the third housing part (1103) in a multi-folded state of the electronic device (1100). As another example, the fourth housing part may be located on the second housing part (1102) in a multi-folded state of the electronic device (1100). If the electronic device (1100) further includes the fourth housing part, the second layer (1270) may include an area that is not attached to the first layer (1250) within an area corresponding to the third hinge structure (e.g., by physically separating the first adhesive layer (1260) within said area corresponding to the third hinge structure).
[0214] FIG. 13 is a plan view showing a plate according to one embodiment.
[0215] Referring to FIG. 13, according to one embodiment, the bendable portion (493) of the plate (490) may protrude relative to the first portion (491) and the second portion (492). For example, the bendable portion (493) of the plate (490) may protrude in a first direction (e.g., +Y direction) parallel to the folding axis (237) relative to the first portion (491) and the second portion (492). Additionally, the bendable portion (493) of the plate (490) may protrude in a second direction (e.g., -Y direction) parallel to the folding axis (237) and opposite to the first direction relative to the first portion (491) of the plate (490) and the second portion (492) of the plate (490).
[0216] The pattern of the plate (490) (e.g., pattern (397 or 597)) has been described as being formed on the bendable portion (493) of the plate (490), but is not limited thereto. For example, the pattern of the plate (490) may be further formed on the first portion (491) of the plate (490) adjacent to the bendable portion (493) of the plate (490), as in pattern (1301), and / or further formed on the second portion (492) of the plate (490) adjacent to the bendable portion (493), as in pattern (1302).
[0217] FIG. 14 is a plan view showing a plate and a protective layer of a display according to one embodiment.
[0218] Referring to FIG. 14, the plate (490) may include a portion that protrudes outward from the protective layer (410) in the direction of the folding axis (237) when the display (330) is viewed from above. For example, when the display (330) is viewed from above, the bendable portion (493) of the plate (490) may protrude outward from the protective layer (410). For example, when the display (330) is viewed from above, the bendable portion (493) of the plate (490) may protrude outward from the protective layer (410) in the first direction (e.g., +Y direction) and the second direction (e.g., -Y direction). For example, the bendable portion (493) of the plate (490) may protrude outward from the protective layer (410) in the first direction (e.g., +Y direction) and the second direction (e.g., -Y direction) over the entire length. In another example, the bendable portion (493) of the plate (490) may include a first section overlapping the folding axis (237) (and / or center plate (363)) and second sections on either side of the first section. The first section of the bendable portion (493) may protrude outward from the protective layer (410) in the first direction (e.g., +Y direction) and the second direction (e.g., -Y direction). The second section of the bendable portion (493) may be recessed inward from the protective layer (410) when the display (330) is viewed from above. Alternatively, the outer edge of the second section of the bendable portion (493) may substantially coincide with the outer edge of the protective layer (410) when the display (330) is viewed from above.
[0219] When the display (330) is viewed from above, a first portion (491) of the plate (490) may protrude outside the protective layer (410). For example, when the display (330) is viewed from above, a first portion (491) of the plate (490) may protrude outside the protective layer (410) in the first direction (e.g., +Y direction) and the second direction (e.g., -Y direction).
[0220] For example, without limitation, when the display (330) is viewed from above, the side (e.g., facing the +X direction) of the first portion (491) of the plate (490) may not protrude from the first side (e.g., facing the +X direction) of the protective layer (410). For example, when the display (330) is viewed from above, the side (e.g., facing the +X direction) of the first portion (491) of the plate (490) may be located on substantially the same vertical plane (e.g., the YZ plane) as the first side (e.g., facing the +X direction) of the protective layer (410). For another example, the side (e.g., facing the +X direction) of the first portion (491) of the plate (490) may be recessed relative to the first side (e.g., facing the +X direction) of the protective layer (410).
[0221] When the display (330) is viewed from above, the second portion (492) of the plate (490) may protrude outside the protective layer (410). For example, when the display (330) is viewed from above, the second portion (492) of the plate (490) may protrude outside the protective layer (410) in the first direction (e.g., +Y direction) and the second direction (e.g., -Y direction).
[0222] For example, the plate (490) may not protrude outside the protective layer (410) in a direction perpendicular to the folding axis (237) when the display (330) is viewed from above. For example, the plate (490) may be recessed inwardly into the protective layer (410) in a direction perpendicular to the folding axis (237). For another example, a portion of the outer edge of the plate (490) may substantially match the outer edge of the protective layer (410) so that the plate (490) does not protrude outside the protective layer (410) in a direction perpendicular to the folding axis (237).
[0223] For example, without limitation, when the display (330) is viewed from above, the side (e.g., facing the -X direction) of the second portion (492) of the plate (490) may not protrude from the second side (e.g., facing the -X direction) of the protective layer (410). For example, when the display (330) is viewed from above, the side (e.g., facing the -X direction) of the second portion (492) of the plate (490) may be located on substantially the same vertical plane (e.g., the YZ plane) as the second side (e.g., facing the -X direction) of the protective layer (410). For another example, the side (e.g., facing the -X direction) of the second portion (492) of the plate (490) may be recessed relative to the second side (e.g., facing the -X direction) of the protective layer (410).
[0224] The electronic device (201) may include a protective member that wraps around at least a portion of the edge of the display (330) to protect the edge of the display (330). The protective member may reduce and / or prevent foreign matter from entering the electronic device (201) by covering the gap between the edge of the display (330) and the foldable housing of the electronic device (201).
[0225] The above protective member may include, for example, a first protective member disposed on a first housing part (210) to cover the edge of a first part (331) of the display (330), and a second protective member disposed on a second housing part (220) to cover the edge of a second part (332) of the display (330). Additionally, the above protective member may include a third protective member disposed on the first housing part (210) and the second housing part (220) to cover the edge of a third part (333) of the display (330), for example.
[0226] To allow bending of the third part (333) of the display (330), the third protective member may be formed of a more flexible material (e.g., rubber) than the first protective member and the second protective member. The third protective member of the display (330) may be supported by an edge portion (e.g., portion (1595) of FIG. 15a) of the bendable portion (493) of the plate (490) that protrudes out of the protective layer (410).
[0227] FIG. 15a is a cross-sectional view showing a display according to one embodiment. FIG. 15b is a plan view showing a display. FIG. 15c is a cross-sectional view showing a display according to one embodiment. FIG. 15d and FIG. 15e are cross-sectional views showing a display according to one embodiment.
[0228] FIGS. 15a, FIGS. 15c, FIGS. 15d, and FIGS. 15e may be drawings showing the A-A' section of FIG. 14. FIG. 15b may be a plan view corresponding to FIG. 15a.
[0229] Referring to FIG. 15a and FIG. 15b, the display (330) may include a side (or edge) facing the first direction (e.g., +Y direction). Layers included in the display (330) may each include a side that defines (or forms) the side of the display (330).
[0230] For example, the protective layer (410) may protrude from the window (420) when viewed from above (e.g., in the -Z direction). For example, the side of the window (420) may be located inside the display (330) (e.g., in the -Y direction) relative to the side of the protective layer (410).
[0231] For example, the adhesive layer (415) may have a shape and / or area corresponding to the protective layer (410), but is not limited to. For example, the side of the adhesive layer (415) may be located on a vertical plane (e.g., the XY plane) substantially the same as the side of the protective layer (410).
[0232] The display panel (430) may protrude from the window (420) when viewed from above (e.g., in the -Z direction). For example, the side of the display panel (430) may be located outside (e.g., in the +Y direction) the side of the window (420).
[0233] For example, the side of the display panel (430) may be located on substantially the same vertical plane (e.g., XZ plane) as the side of the protection layer (410), without limitation.
[0234] For example, the adhesive layer (425) and / or the adhesive layer (440) may have a shape and / or area corresponding to the display panel (430), but is not limited thereto. For example, the side of the adhesive layer (425) and / or the side of the adhesive layer (440) may be located on a vertical plane (e.g., XZ plane) substantially identical to the side of the display panel (430).
[0235] The first layer (450) may have a shape and / or area corresponding to the display panel (430). For example, the side of the first layer (450) may be located on a vertical plane (e.g., XZ plane) substantially identical to the side of the display panel (430).
[0236] The second layer (470) (or the third part (473)) may include a portion (1575) that overlaps the bendable portion (493) of the plate (490) when viewed from above (e.g., in the -Z direction) and protrudes outward from the display panel (430) (e.g., in the +Y direction). For example, the length (D1) of the second layer (470) protruding outward from the display panel (430) may be, for example, about 20 μm, which is not limited.
[0237] For example, but not limited to, the side of the first adhesive layer (460) (e.g., first part (461) and / or second part (462)) may be located on substantially the same vertical plane (e.g., XZ plane) as the side of the second layer (470) (or third part (473)). For example, the first adhesive layer (460) may include a portion (1565) that protrudes outward (e.g., in the +Y direction) of the display panel (430) when viewed from above (e.g., in the -Z direction). For example, the portion (1565) of the first adhesive layer (460) may protrude outward (e.g., in the +Y direction) of the first layer (450) when viewed from above (e.g., in the -Z direction).
[0238] For example, the side of the second adhesive layer (480) may be located on substantially the same vertical plane (e.g., XZ plane) as the side of the second layer (470) (or the third part (473)). For example, the second adhesive layer (480) may include a portion (1585) that protrudes outward (e.g., in the +Y direction) of the display panel (430) when viewed from above (e.g., in the -Z direction).
[0239] The plate (490) (or bendable portion (493)) may include a portion (1595) that protrudes out of the second layer (470) (e.g., in the +Y direction) when the display (330) is viewed from above. For example, the length (D2) of the bendable portion (493) of the plate (490) protruding out of the second layer (470) may be, for example, about 150 μm, which is not limited. The portion (1595) may protrude out of the first layer (450) (e.g., in the +Y direction) when the display (330) is viewed from above.
[0240] Referring to FIG. 15b, the third portion (473) of the second layer (470) may protrude from the first portion (471) of the second layer (470) and the second portion (472) of the second layer (470) (e.g., in the +Y direction). For example, though not limited to, the length (D5) of the third portion (473) of the second layer (470) protruding from the first portion (471) of the second layer (470) and the second portion (472) of the second layer (470) may be about 360 μm.
[0241] Alternatively, referring to FIG. 15c, in the third part (333) of the display (330), the side of the third part (473) of the second layer (470), the side of the first adhesive layer (460), and the side of the second adhesive layer (480) may be located on a vertical plane (e.g., XZ plane) substantially the same as the side of the display panel (430).
[0242] Referring to FIG. 15d, unlike the illustration in FIG. 15a, the display (330) may not include a first layer (450) and an adhesive layer (440) that attaches the first layer (450) to the display panel (430). In this case, the second layer (470) may be attached to the display panel (430) through the first adhesive layer (460) (e.g., a first part (461) and a second part (462)).
[0243] Referring to FIG. 15e, unlike the illustration in FIG. 15a, the display panel (330) may not include a second layer (470) and a first adhesive layer (460) that attaches the second layer (470) to the first layer (450). In this case, the plate (490) may be attached to the first layer (450) through the second adhesive layer (680). When the first adhesive layer (460) and the second layer (470) are omitted, the first portion (651) of the first layer (450) may protrude outward from the display panel (430) (e.g., in the +Y direction) when the display (330) is viewed from above. For example, the first portion (651) of the first layer (450) may protrude outward from the display panel (430) by a length (D1) (e.g., about 20 μm). For example, the first part (651) of the first layer (450) may include a part (1557) that overlaps the first part (491) of the plate (490) when viewed from above (e.g., in the -Z direction) and protrudes outward from the display panel (430) (e.g., in the +Y direction).
[0244] For example, the side of the first portion (641) of the adhesive layer (640) may be located on substantially the same vertical plane (e.g., XZ plane) as the side of the first portion (651) of the first layer (450). For example, the first portion (641) of the adhesive layer (640) may include a portion (1547) that protrudes outward (e.g., in the +Y direction) of the display panel (430) when viewed from above (e.g., in the -Z direction).
[0245] For example, the side of the first portion (681) of the second adhesive layer (680) may be located on substantially the same vertical plane (e.g., XZ plane) as the side of the first portion (651) of the first layer (450). For example, the first portion (681) of the second adhesive layer (680) may include a portion (1587) that protrudes outward (e.g., in the +Y direction) of the display panel (430) when viewed from above (e.g., in the -Z direction).
[0246] A first portion (491) of the plate (490) may include a portion (1597) that protrudes (e.g., in the +Y direction) out of a first portion (651) of the first layer (450) when viewed from above the display (330). For example, the portion (1597) of the plate (490) may protrude out of a first portion (651) of the first layer (450) by a length (D2) (e.g., about 150 μm).
[0247] The description of the first part (641) of the adhesive layer (640), the first part (651) of the first layer (450), and the first part (681) of the second adhesive layer (680), provided with reference to FIG. 15e, may be applied to the second part (642) of the adhesive layer (640), the second part (652) of the first layer (450), and the second part (682) of the second adhesive layer (680) in a substantially the same, similar, or corresponding manner.
[0248] For example, the second part (652) of the first layer (450) may protrude outward from the display panel (430) (e.g., in the +Y direction) when the display (330) is viewed from above. For example, the second part (652) of the first layer (450) may protrude outward from the display panel (430) by a length (D1) (e.g., about 20 μm). For example, the second part (652) of the first layer (450) may include a part (1558) that overlaps with the second part (492) of the plate (490) when viewed from above (e.g., in the -Z direction) and protrudes outward from the display panel (430) (e.g., in the +Y direction).
[0249] For example, the side of the second portion (642) of the adhesive layer (640) may be located on substantially the same vertical plane (e.g., XZ plane) as the side of the second portion (652) of the first layer (450). For example, the second portion (642) of the adhesive layer (640) may include a portion (1548) that protrudes outward (e.g., in the +Y direction) of the display panel (430) when viewed from above (e.g., in the -Z direction).
[0250] For example, the side of the second portion (682) of the second adhesive layer (680) may be located on substantially the same vertical plane (e.g., XZ plane) as the side of the second portion (652) of the first layer (450). For example, the second portion (682) of the second adhesive layer (680) may include a portion (1588) that protrudes outward (e.g., in the +Y direction) of the display panel (430) when viewed from above (e.g., in the -Z direction).
[0251] The second portion (492) of the plate (490) may include a portion (1598) that protrudes (e.g., in the +Y direction) outward from the second portion (652) of the first layer (450) when viewed from above the display (330). For example, the protruding portion (1598) of the second portion (492) of the plate (490) may protrude outward from the second portion (652) of the first layer (450) by a length (D2) (e.g., about 150 μm). The description provided with reference to FIGS. 15a, 15b, 15c, 15d, and 15e may also be applied in a substantially the same, similar, or corresponding manner to the opposite side of the display (330) (e.g., facing the -Y direction), which is not illustrated.
[0252] FIG. 15f is a plan view showing layers of a display according to one embodiment.
[0253] Referring to FIG. 15f, the display (330) may include a first layer (1501) and a second layer (1502). The second layer (1502) may be placed on and / or above the first layer (1501) (e.g., placed in the +Z direction relative to the first layer (1501)).
[0254] For example, the second layer (1502) may be a display panel (430), and the first layer (1501) may be the second layer (470). For example, the second layer (1502) may be a display panel (430), and the first layer (1501) may be the first layer (450).
[0255] The first layer (1501) may include edges (1501a and 1501b) substantially perpendicular to the folding axis (237) and edges (1501c and 1501d) substantially parallel to the folding axis (237). For example, the first edge (1501a) of the first layer (1501) may be opposite to the second edge (1501b) of the first layer (1501). For example, the third edge (1501c) of the first layer (1501) may extend from one end of the first edge (1501a) of the first layer (1501) to one end of the second edge (1501b) of the first layer (1501). For example, the fourth edge (1501d) of the first layer (1501) may extend from the other end of the first edge (1501a) of the first layer (1501) to the other end of the second edge (1501b). For example, the fourth edge (1501d) of the first layer (1501) may be opposite to the third edge (1501c) of the first layer (1501).
[0256] The second layer (1502) may include edges (1502a and 1501b) substantially perpendicular to the folding axis (237) and edges (1502c and 1501d) substantially parallel to the folding axis (237). For example, the first edge (1502a) of the second layer (1502) may be opposite to the second edge (1502b) of the second layer (1502). For example, the third edge (1502c) of the second layer (1502) may extend from one end of the first edge (1502a) of the second layer (1502) to one end of the second edge (1502b) of the second layer (1502). For example, the fourth edge (1502d) of the second layer (1502) may extend from the other end of the first edge (1502a) of the second layer (1502) to the other end of the second edge (1502b). For example, the fourth edge (1502d) of the second layer (1502) may be opposite to the third edge (1502c) of the second layer (1502).
[0257] For example, the first edge (1501a) of the first layer (1501) may face substantially the same direction (e.g., +Y direction) as the first edge (1502a) of the second layer (1502).
[0258] For example, the second edge (1501b) of the first layer (1501) may face substantially the same direction (e.g., -Y direction) as the second edge (1502b) of the second layer (1502).
[0259] For example, the third edge (1501c) of the first layer (1501) may face substantially the same direction (e.g., -X direction) as the third edge (1502c) of the second layer (1502).
[0260] For example, the fourth edge (1501d) of the first layer (1501) may face substantially the same direction (e.g., -X direction) as the fourth edge (1502d) of the second layer (1502).
[0261] The first edge (1501a) of the first layer (1501) may protrude from the first edge (1502a) of the second layer (1502) (e.g., protrude in the +Y direction). For example, the first edge (1502a) of the first layer (1501) may protrude from the first edge (1502a) of the second layer (1502) in the first part (331), second part (332), and third part (333) of the display (330) (e.g., protrude in the +Y direction). For example, the second edge (1501b) of the first layer (1501) may protrude from the second edge (1502b) of the second layer (1502) (e.g., protrude in the -Y direction). For example, the second edge (1502b) of the first layer (1501) may protrude from the second edge (1502b) of the second layer (1502) in the first part (331), second part (332), and third part (333) of the display (330) (e.g., protruded in the -Y direction).
[0262] The third edge (1501c) of the first layer (1501) may be recessed inward from the third edge (1502c) of the second layer (1502) so as not to protrude from the third edge (1502c) of the second layer (1502) (e.g., recessed in the +X direction). The fourth edge (1501d) of the first layer (1501) may be recessed inward from the fourth edge (1502d) of the second layer (1502) so as not to protrude from the fourth edge (1502d) of the second layer (1502) (e.g., recessed in the -X direction).
[0263] Unlike what is illustrated, the third edge (1501c) of the first layer (1501) may overlap (e.g., coincide) with the third edge (1502c) of the second layer (1502), or may protrude from the third edge (1502c) of the second layer (1502) (e.g., protrude in the -X direction). Also, unlike what is illustrated, the fourth edge (1501d) of the first layer (1501) may overlap (e.g., coincide) with the fourth edge (1502d) of the second layer (1502), or may protrude from the fourth edge (1502d) of the second layer (1502) (e.g., protrude in the +X direction). Accordingly, damage to the display (330) caused by bending of the first edge (1502a) and second edge (1502b) (or third edge (1502c), and fourth edge (1502d)) of the second layer (1502) upon external impact can be reduced and / or prevented.
[0264] FIG. 16 is a cross-sectional view of a display according to a comparative example.
[0265] Referring to FIG. 16, the second layer (1670) of the display (1630) of the comparative example may be recessed into the interior of the display panel (430), unlike the second layer (470) of the display (330). In this case, the first adhesive layer (1660) attaching the second layer (1670) to the first layer (450) and the second adhesive layer (1680) attaching the plate (490) to the second layer (1670) may also be recessed into the interior of the display panel (430). Accordingly, the edge portion of the display panel (430) may not be supported. Consequently, upon external impact, the display panel (430) may bend downward, causing the display panel (430) to be damaged. To reduce and / or prevent such problems, the electronic device (201) may include a bonding material attached to the side of the display (1630). This is explained with reference to FIGS. 19a, 19b, 19c, 20a, and 20b.
[0266] Referring again to FIG. 15a, in one embodiment, the durability of the third part (333) of the display (330), which is more vulnerable to impact than the first part (331) and second part (332) of the display panel (430), can be improved through a structure in which the third part (473) of the second layer (470) protrudes outward from the display panel (430). The reason the third part (333) of the display (330) is more vulnerable to impact than the first part (331) and second part (332) of the display (330) may be that the third protective member protecting the third part (333) of the display (330) has less rigidity than the first protective member and the second protective member protecting the first part (331) and second part (332) of the display (330).
[0267] FIG. 17 is a cross-sectional view showing a first part of a display according to one embodiment. FIG. 17 may be a drawing showing the B-B' cross-section of FIG. 14.
[0268] Referring to FIG. 17, in the first part (331) of the display (330), the window (420) may be recessed relative to the display panel (430). The length (D4) of the window (420) recessed relative to the display panel (430) may be about 110 μm.
[0269] In the first part (331) of the display (330), the first part (471) of the second layer (470) may be recessed relative to the display panel (430). The length (D3) of the first part (471) of the second layer (470) recessed relative to the display panel (430) may be greater than the length (D4). For example, the length (D3) may be about 150 μm.
[0270] Unlike in FIG. 14, where the first part (491) of the plate (490) is described as protruding outside the protective layer (410) (or display panel (430)), in the first part (331) of the display (330), the side of the first part (491) of the plate (490) may be located on a vertical plane (e.g., XZ plane) substantially the same as the side of the display panel (430).
[0271] The description provided with reference to FIG. 17 may also be applied in a substantially the same, similar, or corresponding manner to the opposite side (e.g., facing the -Y direction) of the first part (331) of the display (330), which is not illustrated.
[0272] The description provided with reference to FIG. 17 may also be applied to the second part (332) of the display (330), which is not illustrated, in a substantially the same, similar, or corresponding manner.
[0273] FIGS. 18a and FIGS. 18b are cross-sectional views showing a third part of a display according to one embodiment. FIGS. 18a and FIGS. 18b may be drawings showing the A-A' cross-section of FIG. 14.
[0274] Referring to FIG. 18a, in the third part (333) of the display (330), the side of the window (420) may be located on substantially the same plane (e.g., XZ plane) as the side of the display panel (430). Alternatively, referring to FIG. 18b, in the third part (333) of the display (330), the window (420) may protrude outward relative to the display panel (430). In the third part (333) of the display (330), the side of the window (420) may be located on substantially the same vertical plane (e.g., XZ plane) as the side of the second layer (470).
[0275] Although not shown in FIGS. 18a and 18b, an adhesive layer (440) and a first layer (450) may be disposed between the display panel (330) and the first adhesive layer (460). In this case, the display panel (430), the adhesive layer (440), the first layer (450), the first adhesive layer (460), the second layer (470), and the second adhesive layer (480) may be configured as shown in FIG. 15a.
[0276] FIG. 19a is a cross-sectional view showing a display with a bonding material attached according to one embodiment. FIG. 19b and FIG. 19c are drawings showing a method of applying a bonding material.
[0277] Referring to FIG. 19a, an electronic device (201) according to one embodiment may include a bonding material (1900) attached to a side of a display (330). The bonding material (1900) may be formed of a resin or an adhesive material. For example, the bonding material (1900) may be formed of an epoxy-based material having a relatively high modulus.
[0278] The bonding material (1900) may be attached to the side of the display panel (430) corresponding to the bendable portion (493) of the plate (490), the portion (1595) of the second layer (470), the third portion (333) of the display (330), and the side of the window (420) corresponding to the third portion (333) of the display (330). The bonding material (1900) can improve the durability of the display (330) by increasing the rigidity of the edge portion of the display (330).
[0279] Although not shown in FIG. 19a, an adhesive layer (440) and a first layer (450) may be disposed between the display panel (330) and the first adhesive layer (460). In this case, the display panel (430), the adhesive layer (440), the first layer (450), the first adhesive layer (460), the second layer (470), and the second adhesive layer (480) may be configured as shown in FIG. 15a. Additionally, a bonding material (1900) may be further attached to the side of the adhesive layer (440) and the side of the first layer (450).
[0280] Referring to FIG. 19b, a bonding liquid of a bonding material (1900) may be applied before the protective layer (410) is attached to the window (420). To prevent leakage of the bonding liquid, a dam (1904) may be installed on the side of the plate (490). Using a bonding needle (1902), the bonding liquid may be injected into the space between the display (330) and the dam (1904). Since the side of the display (330) includes a step that increases as it goes downward, the bonding liquid may be filled into the space between the display (330) and the dam (1904) by its own weight. Subsequently, the bonding material (1900) may be formed by curing the bonding liquid. After the bonding material (1900) is formed, the dam (1904) may be separated from the display (330). The protective layer (410) can be attached to the window (420) after the injection of the bonding liquid or after the formation of the bonding material (1900).
[0281] Referring to FIG. 19b, an example has been described in which the bonding liquid is injected in the -Z direction through the bonding needle (1902), but this is not limited thereto. For example, referring to FIG. 19c, the bonding needle (1902) may be directed toward the side of the display (330) (e.g., -Y direction), and the bonding liquid may also be applied to the side of the display (330).
[0282] FIGS. 20a and FIGS. 20b are cross-sectional views showing a display with a bonding material attached, according to one embodiment.
[0283] Referring to FIG. 20a and FIG. 20b, according to one embodiment, an electronic device (201) may include a display (1630) and a bonding material (2000) (e.g., a bonding material (1900)) attached to the display (1630).
[0284] In one embodiment, the second layer (1670) of the display (1630) may be drawn into the interior of the display panel (430), unlike the second layer (470) of the display (330). In this case, the first adhesive layer (1660) that attaches the second layer (1670) to the first layer (450) and the second adhesive layer (1680) that attaches the plate (490) to the second layer (1670) may also be drawn into the interior of the display panel (430).
[0285] The bonding material (2000) can be at least partially filled into the groove formed by the layers of the display panel (1630) being drawn in from other layers.
[0286] For example, referring to FIG. 20a, the bonding material (2000) may include a first portion disposed at least partially within a space formed by the second layer (1670) being recessed from the display panel (430) (and / or the first layer (450)) and the plate (490). For example, the first portion of the bonding material (2000) may be disposed at least partially within a gap between the edge portion of the display panel (430) and the bendable portion (493) of the plate (490). For example, the first portion of the bonding material (2000) may be disposed at least partially within a gap between the edge portion of the first layer (450) and the bendable portion (493) of the plate (490). For example, the first portion of the bonding material (2000) may be attached to the side of the first adhesive layer (1660), the side of the second layer (1670), and the side of the second adhesive layer (1680). Additionally, the first portion of the bonding material (2000) may be attached to the back surface of the edge portion of the first layer (450) and to the area of the bendable portion (493) of the plate (490) facing it.
