[0057] For example, the second camera (242) and the third camera (243) may be positioned below (e.g., in the -z direction) the flexible display (230). For example, the second camera (242) and / or the third camera (243) may include an under-display camera (UDC) and / or a punch-hole camera.
[0058] For example, the first housing part (210) and the second housing part (220) may be rotatably coupled. For example, the second housing part (220) may be rotatably coupled to the first housing part (210) via a hinge structure (250) with respect to the first housing part (210).
[0059] For example, the hinge structure (250) can rotatably connect the first housing part (210) and the second housing part (220). The hinge structure (250) can be disposed between the first housing part (210) and the second housing part (220) of the foldable electronic device (101) so that the foldable electronic device (101) can be folded. The hinge structure (250) can enable the foldable electronic device (101) to change from an unfolded state to a folded state. The hinge structure (250) can enable the foldable electronic device (101) to change from a folded state to an unfolded state. The hinge structure (250) can maintain the foldable electronic device (101) in an intermediate state between the unfolded state and the folded state.
[0060] For example, the unfolded state may be referred to as a state in which the first direction toward which the first display area (230a) faces and the second direction toward which the second display area (230b) faces are the same. For example, the folded state may be referred to as a state in which the first direction is opposite to the second direction. When the foldable electronic device (101) is in the folded state, the first housing part (210) and the second housing part (220) may be covered or overlapped.
[0061] For example, when the foldable electronic device (101) is in a folded state and an intermediate state, the first direction and the second direction may be different from each other. For example, when the foldable electronic device (101) is in a folded state, the first direction and the second direction may be opposite to each other. For example, when the foldable electronic device (101) is in an intermediate state, the first direction may have an inclination (e.g., an angle between 0 and 180 degrees) with respect to the second direction.
[0062] For example, the foldable electronic device (101) may be rotatable about a folding axis (f). The folding axis (f) may be referred to as an imaginary line extending along a direction parallel to the longitudinal direction of the foldable electronic device (101) (e.g., the y-axis) or a direction parallel to the width direction of the foldable electronic device (101) (e.g., the x-axis).
[0063] For example, the foldable electronic device (101) may include at least one conductive portion (214a, 224a) and at least one non-conductive portion (214b, 224b) included within the first side (213) and / or the third side (223). For example, the at least one conductive portion (214a, 224a) may be separated from other conductive portions within the first side (213) and / or the third side (223) by being in contact with the at least one non-conductive portion (214b, 224b). The at least one conductive portion (214a, 224a) may operate as an antenna radiator to be used for communication with an external electronic device.
[0064] Referring to FIG. 2C, the hinge structure (250) may include a hinge cover (251), a first hinge plate (252), a second hinge plate (253), and a hinge module (254). The hinge cover (251) may surround internal components of the hinge structure (250) and form an outer surface of the hinge structure (250). For example, at least a portion of the hinge cover (251) may be exposed to the outside of the foldable electronic device (101) through a space between the first housing part (210) and the second housing part (220) when the foldable electronic device (101) is in a folded state. According to one embodiment, when the foldable electronic device (101) is in an unfolded state, the hinge cover (251) may be covered by the first housing part (210) and the second housing part (220) and may not be exposed to the outside of the foldable electronic device (101).
[0065] For example, the first hinge plate (252) and the second hinge plate (253) can be operatively coupled with the first housing part (210) and the second housing part (220), respectively, thereby rotatably connecting the first housing part (210) and the second housing part (220). For example, the first hinge plate (252) can be operatively coupled with the first frame (215) of the first housing part (210), and the second hinge plate (253) can be operatively coupled with the second frame (227) of the second housing part (220). As the first hinge plate (252) and the second hinge plate (253) are operatively coupled to the first frame (215) and the second frame (227), respectively, the first housing part (210) and the second housing part (220) can be rotated according to the rotation of the first hinge plate (252) and the second hinge plate (253).
[0066] The hinge module (254) can rotate the first hinge plate (252) and the second hinge plate (253). For example, the hinge module (254) can rotate the first hinge plate (252) and the second hinge plate (253) about the folding axis (f) by including gears that are interlocked with each other and can rotate.
[0067] For example, the first housing part (210) may include a first frame (215) and a rear cover (216). The first frame (215) may be disposed inside the first housing part (210) and may support at least one component disposed inside the first housing part (210). The rear cover (216) may at least partially form the second surface (222) of the first housing part (210). For example, the second housing part (220) may include a second frame (227). The second frame (227) may be disposed inside the second housing part (220) and may support at least one component disposed inside the second housing part (220). For example, the sub-display (235) may be disposed below (e.g., in the -z direction) the second frame (227).
[0068] An exemplary foldable electronic device (101) may include a plurality of electronic components for implementing various functions, in addition to at least one camera (240) described above. For example, the foldable electronic device (101) may include a first printed circuit board (261), a second printed circuit board (262), a connection structure (e.g., a flexible printed circuit board) (263), and / or a battery (189). The electronic components described above are merely exemplary and are not limited thereto.
[0069] For example, the first printed circuit board (261) and the second printed circuit board (262) may each provide electrical connections between components within the foldable electronic device (101). For example, the first printed circuit board (261) may be disposed within the first housing part (210), and the second printed circuit board (262) may be disposed within the second housing part (220). The first printed circuit board (261) may provide electrical connections between electronic components disposed within the first housing part (210). The second printed circuit board (262) may provide electrical connections between electronic components disposed within the second housing part (220). The connection structure (263) may electrically connect the first printed circuit board (261) and the second printed circuit board (262). For example, the connection structure (263) may extend from the first printed circuit board (261) across the hinge structure (250) to the second printed circuit board (262). For example, the connection structure (263) may at least partially overlap the hinge structure (250).
[0070] For example, the battery (189) may be a device for supplying power to at least one component of the foldable electronic device (101), and may include, for example, a non-rechargeable primary battery and / or a rechargeable secondary battery.
[0071] For example, the foldable electronic device (101) may include a plurality of antennas (ANT1, ANT2, ANT3, ANT4) to be used for communication with an external electronic device. For example, the foldable electronic device (101) may include a main antenna (ANT1), a sub antenna (ANT2), an ultra-wide band (UWB) antenna (ANT3), and / or an antenna for short-range wireless communication (ANT4). However, the present disclosure is not limited thereto.
[0072] Hereinafter, one or more components to be described in more detail with reference to the drawings may be implemented together with the components of the foldable electronic device (101) described with reference to FIGS. 2A, 2B, and 2C. The same reference numerals are assigned to the same components as those described above, and any overlapping descriptions may not be repeated.
[0073] In this disclosure, relative terms such as "above" and "under" may be used to describe relative positions between components. For example, if the foldable electronic device (101) illustrated in the drawing is flipped over, "above" and "under" may be interchanged.
[0074] FIG. 3A illustrates an exemplary display device according to various embodiments. FIG. 3B is an exploded perspective view of an exemplary foldable electronic device according to various embodiments.
[0075] Referring to FIG. 3A, a display device (300) (e.g., the display module (160) of FIG. 1) may include a flexible display (310) (e.g., the flexible display (230) of FIG. 2A) and a display driver integrated circuit (DDI) for driving the flexible display (310). For example, the flexible display (310) may have a structure for electrically connecting to the display driver circuit (340) and a printed circuit board (262). For example, the flexible display (310) may include a first display portion (311), a second display portion (312), and a third display portion (313). The first display portion (311), the second display portion (312), and the third display portion (313) may be referred to as respective portions of a panel forming the flexible display (310).
[0076] For example, the first display portion (311) may include an active area for providing visual information. For example, the active area may include a plurality of pixels for displaying visual information. For example, the pixels may be referred to as the smallest unit forming an image when visually displaying an image. The first display portion (311) may output an image and / or text using a plurality of pixels within the active area. Since the first display portion (311) includes an active area for providing visual information, it may be referred to as a display portion or a display area.
[0077] For example, the second display portion (312) may be opposite to the first display portion (311). For example, the second display portion (312) may be positioned below (e.g., in the -z direction) the first display portion (311). For example, the second display portion (312) may be spaced apart from the first display portion (311). For example, the second display portion (312) positioned below the first display portion (311) may be electrically connected to the display driving circuit (340) and the printed circuit board (262). For example, the display driving circuit (340) may be positioned on the back surface (e.g., the surface facing the -z direction) of the second display portion (312). Since the display driving circuit (340) is positioned on the second display portion (312), the display device (300) may be referred to as a COP (chip on plastic) structure. For example, the printed circuit board (262) may be electrically connected to the second display portion (312), thereby electrically connecting the printed circuit board (262) and the display driving circuit (340). For example, the printed circuit board (262) may be a component included in the foldable electronic device (101) illustrated in FIG. 3B and described in more detail below.
[0078] The display driving circuit (340) may be configured to provide visual information through the flexible display (310) based on receiving a control signal and / or data from at least one processor (e.g., the processor (120) of FIG. 1). For example, the at least one processor may be disposed on the printed circuit board (262). Since the display driving circuit (340) is electrically connected to the printed circuit board (262) through the second display portion (312), the at least one processor may provide the control signal and / or data to the display driving circuit (340) through the printed circuit board (262) and the second display portion (312). For example, the display driving circuit (340) may control the operation of a plurality of pixels based on receiving the control signal and / or data from the processor. The display driving circuit (340) may include a Gate IC that controls on / off of sub-pixels included in a plurality of pixels and a Source IC that controls visual information expressed by the sub-pixels.
[0079] For example, the third display portion (313) can connect the first display portion (311) and the second display portion (312), which are spaced apart from each other. For example, the third display portion (313) can extend from the first display portion (311) to the second display portion (312). For example, the third display portion (313) can be bent to have a curvature with respect to the first display portion (311) and the second display portion (312). For example, the third display portion (313) can be flexible.
[0080] For example, in order to control a plurality of pixels within an active area, an electrical connection between the display driving circuit (340) and the first display portion (311) may be required. The electrical connection between the display driving circuit (340) and the first display portion (311) may be provided by the second display portion (312) and the third display portion (313). The display driving circuit (340) may be electrically connected to the second display portion (312) by being disposed on the second display portion (312). The second display portion (312) may be electrically connected to the first display portion (311) via the third display portion (313). By the above structure, an electrical connection between the display driving circuit (340) and the first display portion (311) may be established. For example, the first display portion (311) may be referred to as a panel portion, and the second display portion (312) and the third display portion (313) may be referred to as panel extension portions. For example, the display device (300) may include a plurality of layers. The plurality of layers arranged within the display device (300) will be described in more detail with reference to FIGS. 7A and 7B.
[0081] Referring to FIG. 3B, an exemplary foldable electronic device (101) may include a housing (201) forming an exterior of the foldable electronic device (101). The housing (201) may include a housing (201) having a rotatable structure. For example, the housing (201) may include a first housing part (210) and a second housing part (220) rotatable with respect to the first housing part (210). The first housing part (210) and the second housing part (220) may be rotatable with respect to a folding axis (f). For example, the foldable electronic device (101) may include a first frame (215) for supporting components associated with the first housing part (210) and a second frame (227) for supporting components associated with the second housing part (220). At least a portion of the first frame (215) may be wrapped by a first side bezel structure (271), and at least a portion of the second frame (227) may be wrapped by a second side bezel structure (272). The display device (300) illustrated in FIG. 3A may be included in a foldable electronic device (101).
[0082] The exemplary foldable electronic device (101) may include protective members (273, 274) for protecting the edges of the flexible display (310). For example, the protective members (273, 274) may form a part of the housing (201). For example, the first display portion (311) may be at least partially supported by the first frame (215) and the second frame (227). Although not shown, the exemplary foldable electronic device (101) may include adhesive members (e.g., double-sided tape) for attaching the flexible display (310) to the first frame (215) and the second frame (227). For example, the edge of the flexible display (310) may be exposed to the outside of the foldable electronic device (101) by being spaced apart from the first side bezel structure (271) and the second side bezel structure (272). The protective members (273, 274) may at least partially cover the exposed edge of the flexible display (310). For example, the first protective member (273) may cover the edge of the first display portion (311) forming at least a portion of the front surface of the first housing part (210). For example, the second protective member (274) may cover the edge of the second display portion (312) forming at least a portion of the front surface of the second housing part (220). The edge of the flexible display (310) may not be exposed to the outside of the foldable electronic device (101) by being at least partially covered by the protective members (273, 274). The protective members (273, 274) can reduce damage to the flexible display (310).
[0083] For example, the third display portion (313) may be positioned above the second frame (227) (e.g., in the +z direction). The third display portion (313) may protrude toward the second side bezel structure (272) because it extends from the first display portion (311) to the second display portion (312) positioned below the first display portion (311). The second protective member (274) may be positioned above the third display portion (313) to cover the third display portion (313). For example, the size of the second display portion (312) may be smaller than the size of the first display portion (311). The first display portion (311) may at least partially form the front surface of the first housing portion (210) and the front surface of the second housing portion (220). The second display part (312) can be located inside the second housing part (220).
[0084] For example, since the folding axis (f) may be positioned between the first protective member (273) and the second protective member (274), the first protective member (273) and the second protective member (274) may be spaced apart from each other with the folding axis (f) therebetween. The exemplary foldable electronic device (101) may include a cap (275) for covering the gap between the first protective member (273) and the second protective member (274).
[0085] FIG. 4 is a drawing illustrating a portion of a housing of an exemplary foldable electronic device according to various embodiments.
[0086] Referring to FIG. 4, an exemplary foldable electronic device (101) may include a housing (201), a hinge structure (250), and magnets (M1, M2).
[0087] For example, the foldable electronic device (101) may include a first frame (215) and a second frame (227) disposed inside the housing (201). For example, the first frame (215) may support a portion of a flexible display (e.g., the flexible display (310) of FIG. 3B). For example, the portion of the flexible display (310) supported by the first frame (215) may be a portion of the flexible display (310) that forms at least a portion of the front surface (e.g., the surface in the +z direction) of the first housing part (210). For example, the second frame (227) may support another portion of the flexible display (310). For example, the other part of the flexible display (310) supported by the first frame (215) may be a part of the flexible display (310) that forms at least a part of the front surface of the second housing part (220).
[0088] For example, the hinge structure (250) can rotatably connect the first housing part (210) and the second housing part (220). For example, the hinge structure (250) can include a first hinge plate operatively coupled with the first frame (215) and a second hinge plate operatively coupled with the second frame (227). For example, rotation of the second hinge plate with respect to the first hinge plate can cause rotation of the second frame (227) with respect to the first frame (215). Rotation of the second frame (227) with respect to the first frame (215) can cause rotation of the second housing part (220) with respect to the first housing part (210). For example, the foldable electronic device (101) can be in a folded state, an unfolded state, and a plurality of intermediate states. The hinge structure (250) can provide the above states of the foldable electronic device (101).
[0089] An exemplary foldable electronic device (101) may include a first waterproof structure (410) and a second waterproof structure (420). For example, the first waterproof structure (410) may form a first waterproof space (S1) between the portion of the flexible display (310) and the first frame (215). For example, the first waterproof structure (410) may be formed by a first waterproof tape (411). For example, the first waterproof tape (411) may attach the portion of the flexible display (310) onto the first frame (215).
[0090] As illustrated in FIG. 4, the first waterproof tape (411) may have a closed loop shape, thereby forming a first waterproof space (S1). For example, the first waterproof tape (411) may be spaced apart from the first magnet (M1). The first waterproof tape (411) forming the first waterproof space (S1) may reduce the inflow of moisture into the first waterproof space (S1). For example, electronic components and / or electronic circuits placed within the first waterproof space (S1) wrapped by the first waterproof tape (411) may be protected from moisture and / or foreign substances.
[0091] For example, the second waterproof structure (420) can form a second waterproof space (S2) between the other part of the flexible display (310) and the second frame (227). For example, the second waterproof structure (420) can be formed by a second waterproof tape (421), a third waterproof tape (422), and a resin portion (423). For example, the second waterproof tape (421) can be disposed between the second display portion (312) and the second frame (227), thereby attaching the second display portion (312) onto the second frame (227). For example, the second waterproof tape (421) can be attached to each of the second frame (227) and the second display portion (312) located inside the second housing part (220). For example, the second waterproof tape (421) may extend along the extension direction (e.g., y-axis) of the folding axis (f). For example, the third waterproof tape (422) may attach the first display portion (311) to the second frame (227). For example, the third waterproof tape (422) may be disposed on the outside of the second display portion (312) on the second frame (227). The gap between the second waterproof tape (421) and the third waterproof tape (422) may be stepped due to the second display portion (312). The gap caused by the step between the second waterproof tape (421) and the third waterproof tape (422) may be filled by the resin portion (423). By filling the gap with the resin portion (423), the second waterproof tape (421), the third waterproof tape (422), and the resin portion (423) can form a closed loop. By the closed loop, a second waterproof space (S2) can be formed. As the second waterproof space (S2) is formed, the inflow of moisture into the second waterproof space (S2) can be reduced.For example, electronic components and / or electronic circuits placed within the first waterproof space (S1) wrapped by the second waterproof tape (421), the third waterproof tape (422), and the resin portion (423) can be protected from moisture and / or foreign substances.
[0092] An exemplary foldable electronic device (101) may include magnets (M1, M2) for maintaining a folded state of the foldable electronic device (101). For example, the foldable electronic device (101) may include a first magnet (M1) and a second magnet (M2). For example, the first magnet (M1) may be disposed below the flexible display (310) (e.g., in the -z direction). For example, the first magnet (M1) may be disposed inside the first frame (215). For example, the second magnet (M2) may be disposed below the flexible display (310). For example, the second magnet (M2) may be disposed inside the second frame (227). The second magnet (M2) may be paired with the first magnet (M1) to maintain the folded state of the foldable electronic device (101). For example, in the folded state of the foldable electronic device (101), the folded state may be maintained by the attractive force between the first magnet (M1) and the second magnet (M2). By an external force greater than the attractive force, the foldable electronic device (101) may be changed from the folded state to the unfolded state. For example, the first magnet (M1) may be arranged adjacent to the edge of the first frame (215), and the second magnet (M2) may be arranged adjacent to the edge of the second frame (227).
[0093] FIG. 5 is a drawing illustrating the back of an exemplary flexible display with the second display portion omitted according to various embodiments.
[0094] For convenience of explanation, a third display portion (e.g., the third display portion (313) of FIG. 3A) connected to one side of the first display portion (311) and a second display portion (e.g., the second display portion (312) of FIG. 3A) connected to the third display portion (313) are omitted in FIG. 5.
[0095] For example, a plurality of layers may be interposed between the first display portion (311) and the second display portion (312). For example, the plurality of layers may include a first layer (320) and a second layer (330). For example, the first layer (320) may include an electromagnetic induction panel (e.g., an electromagnetic induction panel (321) of FIG. 6B) and / or a conductive sheet (e.g., a conductive sheet (322) of FIG. 7A). For example, the first layer (320) may be disposed below the first display portion (311) (e.g., in the -z direction). For example, the second layer (330) may be disposed below the first layer (320). The laminated structure and components of the first layer (320) and the second layer (330) will be described later.
[0096] Referring to FIG. 5, the second layer (330) may include a shielding member (331) and a waterproofing member (332). For example, the shielding member (331) may reduce interference between a second magnet (e.g., the second magnet (M2) of FIG. 4) and an electromagnetic induction panel (321) (e.g., see FIG. 6a). For example, the shielding member (331) may be positioned between the second magnet (M2) and a portion of the electromagnetic induction panel (321) positioned above the second magnet (M2). For example, the size of the electromagnetic induction panel (321) may correspond to the size of the second magnet (M2).
[0097] For example, the waterproofing member (332) can surround the shielding member (331) within the second layer (330). For example, the waterproofing member (332) can reduce moisture inflow through the gap by filling the gap between the first display portion (311) and the second display portion (312). For example, the waterproofing member (332) can include an adhesive and / or a flexible material (e.g., butyl rubber, foam, polyethylene, and / or polyurethane).
[0098] For example, the shielding member (331) and the waterproofing member (332) disposed within the same layer (e.g., the second layer (330)) may be disposed substantially on the same plane. For example, the shielding member (331) may be disposed within the second layer (330) on substantially the same plane as the waterproofing member (332). The shielding member (331) being disposed substantially on the same plane as the waterproofing member (332) may be referred to as meaning that the shielding member (331) and the waterproofing member (332) do not overlap, and that the shielding member (331) is disposed parallel to the waterproofing member (332). As illustrated in FIG. 5, the waterproofing member (332) may be disposed to avoid the shielding member (331). Since the waterproof member (332) and the shielding member (331) are not overlapped but are arranged in parallel on the same layer, the thickness of the flexible display (310) can be reduced.
[0099] FIG. 6A is a cross-sectional view taken along line A-A' of FIG. 2A of an exemplary foldable electronic device according to various embodiments. FIG. 6B is an enlarged cross-sectional view of a portion of a display device according to various embodiments.
[0100] Referring to FIG. 6A, the second protective member (274) can protect the flexible display (310) by covering a portion of the flexible display (310). The third display portion (313) can be covered by the second protective member (274). For example, a plurality of layers can be arranged between the first display portion (311) and the second display portion (312). For example, the plurality of layers can include a first layer (320) and a second layer (330). For example, the first layer (320) can include an electromagnetic induction panel (321). For example, the second layer (330) can include a shielding member (331) and a waterproof member (332).
[0101] For example, the electromagnetic induction panel (321) may be configured to receive input from an external electronic device. For example, the external electronic device may include an electronic pen and / or a stylus pen configured to provide input through the electromagnetic induction panel (321). The electromagnetic induction panel (321) may be configured to receive a hovering input or a touch input on the flexible display (310). For example, the electromagnetic induction panel (321) may be referred to as an electromagnetic resonance (EMR) panel and / or a digitizer.
[0102] For example, the electromagnetic induction panel (321) may be configured to transmit an electromagnetic signal to an external electronic device or receive an electromagnetic signal from an external electronic device. For example, at least one processor (e.g., the processor (120) of FIG. 1) may transmit a first electromagnetic signal to the external electronic device through the electromagnetic induction panel (321). The first electromagnetic signal received by the external electronic device may cause electromagnetic resonance within the external electronic device. For example, the first electromagnetic signal may cause electromagnetic induction of a coil within the external electronic device. A second electromagnetic signal generated by the electromagnetic resonance within the external electronic device may be transmitted to the electromagnetic induction panel (321). For example, the external electronic device may generate the second electromagnetic signal based on a current within the coil generated by electromagnetic induction and transmit the generated second electromagnetic signal to the electromagnetic induction panel (321). By the current generated by the electromagnetic induction, the external electronic device can generate a second electromagnetic signal without a separate power supply. The second electromagnetic signal received by the electromagnetic induction panel (321) can cause electromagnetic resonance within the electromagnetic induction panel (321). At least one processor can identify an input from the external electronic device based on the third electromagnetic signal generated by the electromagnetic resonance within the electromagnetic induction panel (321). However, the present disclosure is not limited thereto.
[0103] For example, the shielding member (331) may be positioned between a second magnet (M2) positioned below the flexible display (310) (e.g., in the -z direction) and a portion of the electromagnetic induction panel (321) positioned above the second magnet (M2) (e.g., in the +z direction). The portion of the electromagnetic induction panel (321) positioned above the second magnet (M2) may be referred to as a portion that overlaps the second magnet (M2) within the electromagnetic induction panel (321).
[0104] For example, the above-mentioned part of the electromagnetic induction panel (321) may be positioned above the second magnet (M2) arranged in the second frame (227). The shielding member (331) may reduce the influence of the magnetic field formed by the second magnet (M2) on the electromagnetic induction panel (321). For example, the magnetic field formed by the second magnet (M2) may interfere with the electromagnetic induction panel (321). For example, the magnetic field formed by the second magnet (M2) may affect electromagnetic resonance caused in the electromagnetic induction panel (321) by an external electronic device, thereby causing a malfunction of the electromagnetic induction panel (321). A shielding member (331) may be placed between the second magnet (M2) and a portion of the electromagnetic induction panel (321) positioned above the second magnet (M2) to reduce the influence of the magnetic field formed by the second magnet (M2) on the electromagnetic induction panel (321). To reduce the influence, the size of the shielding member (331) may correspond to the size of the portion of the electromagnetic induction panel (321) or may be larger than that. For example, the shielding member (331) may include an amorphous ribbon sheet (ARS). The shielding member (331) may include a shielding sheet.
[0105] Since the second display portion (312) is spaced apart from the first display portion (311), a gap may be formed between the first display portion (311) and the second display portion (312). If the gap is an empty space, moisture and / or foreign substances may enter through the gap. For example, if moisture enters through the gap, damage to the flexible display (310) may be caused by the moisture. For example, the waterproof member (332) may reduce the inflow of moisture through the gap by filling the gap between the first display portion (311) and the second display portion (312). For example, the waterproof member (332) may include a spacer that fills the empty space by occupying the empty space. For example, the waterproof member (332) may be flexible so as to be able to fill the gap.
[0106] For example, the waterproof member (332) may be arranged parallel to the shielding member (331). For example, the waterproof member (332) and the shielding member (331) may be arranged in different layers without overlapping each other, but may be arranged in the same layer (e.g., the second layer (330)). For example, the waterproof member (332) and the shielding member (331) may be arranged on substantially the same plane. For example, when the shielding member (331) is arranged on the waterproof member (332), the distance between the first display portion (311) and the second display portion (312) increases, and thus the thickness of the flexible display (310) may increase. As the thickness increases, the curvature of the third display portion (313) connecting the first display portion (311) and the second display portion (312) may increase, and the thickness of the second frame (227) may increase for mounting space of electronic components (e.g., speakers and / or batteries) overlapping the second display portion (312). The exemplary foldable electronic device (101) may include a waterproof member (332) and a shielding member (331) arranged parallel to each other within the same layer (e.g., the second layer (330)), thereby reducing the distance between the first display portion (311) and the second display portion (312). By reducing the distance, the thickness of the flexible display (310) and the thickness of the second frame (227) may become thinner, and the curvature of the third display portion (313) may be reduced.
[0107] Referring to FIG. 6B, the first layer (320) may include an electromagnetic induction panel (321) disposed below (e.g., in the -z direction) the first display portion (311). For example, the second layer (330) may be in contact with the second display portion (312) (e.g., the second polymer film (3112)) between the first layer (320) and the second display portion (312). The second layer (330) may be interposed between the first layer (320) and the second display portion (312).
[0108] For example, the second layer (330) may include a first side (330a) and a second side (330b). For example, the first side (330a) may be a side of the second layer (330) that faces the first display portion (311). For example, the first side (330a) may face in the +z direction. The second side (330b) may be opposite to the first side (330a). For example, the second side (330b) may be a side of the second layer (330) that faces the second display portion (312). For example, the second side (330b) may face in the -z direction. Referring to FIG. 6b, the first side (330a) can be in contact with the first layer (320), and the second side (330b) can be in contact with the second display portion (312).
[0109] For example, the first display portion (311) and the second display portion (312) may include at least one polymer film (3111, 3112), which is a base substrate. For example, the first display portion (311) may include a first polymer film (3111), and the second display portion (312) may include a second polymer film (3112). The at least one polymer film (3111, 3112) may have high heat resistance, transparency, and electrical properties, thereby protecting the flexible display (310) and improving the electrical properties of the flexible display (310). For example, the at least one polymer film (3111, 3112) may include a PI (polyimide) film. However, the present disclosure is not limited thereto.
[0110] For example, the second polymer film (3112) may be in contact with the second layer (330). For example, the second layer (330) may further include an adhesive member (333) that attaches the shielding member (331) onto the polymer film (3112). For example, the adhesive member (333) may include, but is not limited to, an optically clear adhesive (OCA). The adhesive member (333) may include an adhesive sheet. The adhesive member (333) may attach the shielding member (331) onto the second polymer film (3112). For example, if the shielding member (331) is interposed between the first layer (320) and the second polymer without the adhesive member (333), the shielding member (331) may not be fixed. Due to the unfixed shielding member (331), wrinkles and damage may occur in the flexible display (310). The adhesive member (333) can reduce the wrinkles and damage by fixing the shielding member (331) by attaching the shielding member (331) onto the second polymer film (3112).
[0111] For example, the second layer (330) may further include a support member (334) interposed between the first layer (320) and the waterproof member (332). For example, the support member (334) may include a conductive material (e.g., copper) and / or a non-conductive material (e.g., polyethylene terephthalate (PET)). However, the present disclosure is not limited thereto. The support member (334) may form the thickness of the second layer (330) by filling the space between the waterproof member (332) and the first layer (320). The support member (334) may compensate for the difference in thickness between the shielding member (331) and the adhesive member (333) and the waterproof member (332). For example, the thicknesses of the shielding member (331) and the adhesive member (333) may correspond to the thicknesses of the waterproof member (332) and the support member (334). For example, the thickness of the shielding member (331) may be about 80 um to 100 um, and the thickness of the adhesive member (333) may be about 20 um to about 30 um. For example, the thickness of the waterproofing member (332) may be about 80 um to 100 um, and the thickness of the support member (334) may be about 20 um to about 30 um. The thicknesses of the shielding member (331) and the adhesive member (333) correspond to the thicknesses of the waterproofing member (332) and the support member (334), so that the overall thickness of the second layer (330) may be substantially constant. For example, the thickness of the second layer (330) may be about 100 um to about 130 um. If a shielding member (331) and a waterproofing member (332) having the same thickness as the aforementioned thickness are overlapped, the thickness of the second layer (330) may be about 160 um to about 200 um. Since the shielding member (331) and the waterproofing member (332) are arranged in parallel within the second layer (330), the thickness of the second layer (330) may be relatively thin. The aforementioned thickness values are merely exemplary, and the present disclosure is not limited thereto.
[0112] Referring to FIGS. 6A and 6B , various components may be positioned within the display device (300). For example, a barrier member (e.g., the barrier member (350) of FIG. 6B ) and / or a polymer member (e.g., the polymer member (360) of FIG. 6B ) may be positioned between the first polymer film (3111) and the first layer (320). For example, the barrier member (350) may reduce wrinkling of the first display portion (311) that may be caused by a spaced-off area between the shielding member (331) and the waterproofing member (332). For example, the polymer member (360) may include a polymer having rigidity (e.g., carbon fiber reinforced plastic (CFRP). The polymer member (360) may support the first display part (311). For example, a protective tape (370) for discharging static electricity may be placed under (e.g., in the -z direction) the second display part (312). For example, a bending protection layer (BPL) (313a) for protecting the bent third display part (313) may be placed on the outer surface of the third display part (313). For example, a protective sheet (e.g., the protective sheet (391) of FIG. 6a) for protecting the active area may be placed on (e.g., in the +z direction) the first display part (311). For example, a polarizing layer (e.g., a polarizing layer) for reducing the amount of light reflected within the active area may be placed on (e.g., in the +z direction) the first display part (311). A polarizing layer (392) of 6a may be placed. In addition, various components may be placed within the display device (300).
[0113] FIG. 7A is a cross-sectional view illustrating an exemplary foldable electronic device according to various embodiments, taken along line B-B' of FIG. 2A. FIG. 7B is a cross-sectional view schematically illustrating an exemplary foldable electronic device according to various embodiments, taken along line C-C' of FIG. 2A.
[0114] Referring to FIGS. 7A and 7B, the third display portion (313) may be positioned inside the second housing portion (220) among the first housing portion (210) and the second housing portion (220). For example, the third display portion (313) may be extended from one end (311a) of the first display portion (311) included in the second housing portion (220) to one end (312a) of the second display portion (312) within the second housing portion (220) by being at least partially bent. For example, the second display portion (312) may be extended from one end (312a) of the second display portion (312) to a point within the second housing portion (220). For example, the second display portion (312) may not be positioned within the first housing portion (210).
[0115] For example, the display device (300) may include a plurality of layers. For example, the plurality of layers may be interposed between the first display portion (311) and the second display portion (312). For example, the plurality of layers may include, but are not limited to, the first layer (320) and the second layer (330) described above. For example, the plurality of layers may further include a support plate (710) disposed below (e.g., in the -z direction) the first display portion (311), a step compensation film (720) disposed below the grid portion (710a) of the support plate (710), and / or adhesive members (730) interposed between the first display portion (311) and the support plate (710) and / or between the first layer (320) and the support plate. For example, the adhesive members (730) may include a pressure sensitive adhesive (PSA).
[0116] For example, the support plate (710) may be disposed under the first polymer film (3111) of the first display portion (311) to support the first display portion (311). The support plate (710) may include a lattice portion (710a) for a folded state of the foldable electronic device (101). The lattice portion (710a) may include a lattice structure formed by a plurality of openings and / or a plurality of recesses. For example, when the foldable electronic device (101) is in a folded state, the support plate (710) may be bent by the lattice portion (710a).
[0117] For example, a step compensation film (720) may be positioned within the gap to compensate for the gap formed for the folded state. For example, as illustrated in FIGS. 7A and 7B , the step compensation film (720) may be positioned within the gap between the adhesive members (730), but is not limited thereto. The step compensation film (720) may be flexible. In addition, the plurality of layers may include various components.
[0118] Referring to FIG. 7a, a shielding member (e.g., a shielding member (331) of FIG. 7b) may be omitted within a position spaced apart from the first magnet (e.g., a first magnet (M1) of FIG. 7b) and the second magnet (e.g., a second magnet (M2) of FIG. 7b). Since the shielding member (331) is a component for reducing interference between the first magnet (M1) and the second magnet (M2) and the electromagnetic induction panel (321), it may be omitted within a position spaced apart from the first magnet (M1) and the second magnet (M2). For example, the first layer (320) may further include a conductive sheet (322). The conductive sheet (322) may be attached to the electromagnetic induction panel (321) below the electromagnetic induction panel (321). For example, the conductive sheet (322) can reduce electromagnetic waves transmitted from the inside of the foldable electronic device (101) to the electromagnetic induction panel (321) and / or electromagnetic waves transmitted from an external electronic device (e.g., an electronic pen and / or a stylus pen) to the inside of the foldable electronic device (101). For example, the conductive sheet (322) can include magnetic metal powder (MMP). For example, the magnetic metal powder can include, but is not limited to, iron, aluminum, nickel, and / or silicon. For example, a second layer (330) disposed under the first layer (320) can be in contact with the conductive sheet (322). For example, since the electromagnetic induction panel (321) is rigid, it can include a first electromagnetic induction panel (321a) and a second electromagnetic induction panel (321b) that are separated for a folded state of the foldable electronic device (101). For example, the first electromagnetic induction panel (321a) may be placed within the first housing part (210), and the second electromagnetic induction panel (321b) may be placed within the second housing part (220). The first electromagnetic induction panel (321a) and the second electromagnetic induction panel (321b) may be spaced apart from each other with the folding axis (f) therebetween.
[0119] For example, the first layer (320) may further include a reinforcing member (323). For example, the reinforcing member (323) may be disposed below the electromagnetic induction panel (321). For example, the reinforcing member (323) may be rigid. The rigid reinforcing member (323) may support the first display portion (311). When the conductive sheet (322) is included in the first layer (320), the reinforcing member (323) may be disposed below the conductive sheet (322). Since the reinforcing member (323) is rigid, it may include a separated first reinforcing member (323a) and a second reinforcing member (323b) for a folded state of the foldable electronic device (101). For example, the first reinforcing member (323a) may be placed within the first housing part (210), and the second reinforcing member (323b) may be placed within the second housing part (220). The first reinforcing member (323a) and the second reinforcing member (323b) may be spaced apart from each other with the folding axis (f) therebetween. For example, the reinforcing member (323) may be omitted.
[0120] For example, the foldable electronic device (101) may include waterproof structures that provide waterproof spaces. For example, the foldable electronic device (101) may include a first waterproof tape (411) forming a first waterproof structure (410). For example, the foldable electronic device (101) may include a second waterproof tape (421), a third waterproof tape (422), and a resin portion (e.g., the resin portion (423) of FIG. 4) forming a second waterproof structure (420). The waterproof structures may reduce the ingress of moisture and / or foreign substances between the display device (300) and the first frame (215) and between the display device (300) and the second frame (227). For example, the first waterproof tape (411) having a closed-loop shape may be attached to the first layer (320) and the first frame (215). For example, the second waterproof tape (421) may be attached to the second display portion (312) and the second frame (227). For example, the third waterproof tape (422) may be attached to the first layer (320) and the second frame (227). For example, a cushion (740) may be placed in the first waterproof space (S1) and the second waterproof space (S2). The cushion (740) may reduce damage to the display device (300) by absorbing external impact. The above-described waterproof tapes (e.g., the first waterproof tape (411), the second waterproof tape (421), and the third waterproof tape (422)) may be distinguished from the waterproof member (e.g., the waterproof member (332) of FIG. 7B) in the second layer (330) because they attach the display device (300) to the first frame (215) and / or the second frame (227).
[0121] Referring to FIG. 7b, the second layer (330) may include a shielding member (331) within a position overlapping the first magnet (M1) and the second magnet (M2). For example, the second layer (330) may be positioned between the first layer (320) and the second display portion (312). For example, the second layer (330) may be in contact with the first layer (320) and the second display portion (312).
[0122] For example, the shielding member (331) may be placed above the second magnet (M2) (e.g., in the +z direction). For example, when the display device (300) is viewed from above (e.g., in the -z direction), the second magnet (M2) may overlap the shielding member (331). The size of the shielding member (331) may correspond to the size of the second magnet (M2) or may be larger than the size of the second magnet (M2). The shielding member (331) may reduce the influence of the magnetic field formed by the second magnet (M2) on a portion of the electromagnetic induction panel (321) positioned above the second magnet (M2). For example, the portion of the electromagnetic induction panel (321) positioned above the second magnet (M2) may be a portion of the second electromagnetic induction panel (321b) that overlaps the second magnet (M2). For example, when a conductive sheet (322) is included in the first layer (320), the electromagnetic induction panel (321) may have a double shielding structure by the conductive sheet (322) and the shielding member (331). For example, the conductive sheet (322) and the shielding member (331) may improve electromagnetic interference (EMI).
[0123] For example, since the second display portion (312) is not included within the first housing part (210), another shielding member (750) may be placed over the first magnet (M1). The other shielding member (750) may be substantially identical to the shielding member (331). The other shielding member (750) may reduce interference between the first magnet (M1) and the first electromagnetic induction panel (321a).
[0124] Referring to FIG. 7B, since the shielding member (331) and the waterproofing member (332) are arranged parallel within the second layer (330), the thickness of the second layer (330) can be relatively thinned. For example, when the shielding member (331) and the waterproofing member (332) are arranged to overlap, the thickness of the second layer (330) can be determined by the thicknesses of the shielding member (331) and the waterproofing member (332). For example, when the shielding member (331) is arranged on the waterproofing member (332), the thickness of the second layer (330) can become relatively thick. Due to the increase in the thickness of the second layer (330), the distance between the first display portion (311) and the second display portion (312) can be increased. As the thickness increases, the curvature of the third display portion (313) may increase, and the thickness of the second frame (227) may increase. The exemplary foldable electronic device (101) may include a waterproof member (332) and a shielding member (331) that are arranged parallel to each other within the same layer (e.g., the second layer (330)), thereby reducing the curvature of the third display portion (313), and reducing the thickness of the display device (300) and the foldable electronic device (101). For example, when the shielding member (331) is arranged parallel to the waterproof member (332), the shielding member (331) may have a relatively thicker thickness compared to when the shielding member (331) overlaps the waterproof member (332). As the thickness of the shielding member (331) becomes relatively thicker, the effect of reducing interference between the second magnet (M2) and the above-mentioned portion of the electromagnetic induction panel (321) can be improved.
[0125] FIG. 8A is an enlarged view of portion X of FIG. 5. FIG. 8B is a cross-sectional view illustrating a cross-section taken along line D-D' of the foldable electronic device of FIG. 8A according to various embodiments.
[0126] Referring to FIG. 8A, the second display portion (312) may extend from the third display portion (313) to a point within the second housing part (220). For example, the second display portion (312) may not extend beyond the hinge structure (e.g., the hinge structure (250) of FIG. 2C) to the first housing part (210), but may be positioned only within the second housing part (220). Due to the thickness of the second display portion (312), a step may be formed between the front surface of the second frame (227) and the second display portion (312).
[0127] For example, the second waterproof structure (420) may form a second waterproof space (S2). For example, the second waterproof structure (420) may include a second waterproof tape (421), a third waterproof tape (422), and a resin portion (423). The second waterproof tape (421) and the third waterproof tape (422) may not be connected to each other but may be spaced apart from each other by the step. If the second waterproof tape (421) and the third waterproof tape (422) are connected, a wrinkle may be formed by the step. A gap may be formed between the front surface of the second frame (227) and the second waterproof structure (420) by the wrinkle. Moisture and / or foreign substances may enter the second waterproof space (S2) through the gap, which may cause damage to the flexible display (310).
[0128] For example, the second waterproof structure (420) may include a resin portion (423) for filling a gap between the second waterproof tape (421) and the third waterproof tape (422). For example, the waterproof member (332) may include a portion protruding outside the second display portion (312). For example, the waterproof member (332) may include a first portion (332a) that comes into contact with the second display portion (312) and a second portion (332b) that protrudes from the second display portion (312). Referring to FIG. 8B, the resin portion (423) may be formed between the second waterproof tape (421) and the third waterproof tape (422). For example, the resin portion (423) may be referred to as a sealing member for filling the gap and reducing leakage of the second waterproof space (S2). For example, the resin portion (423) can cover the second portion (332b) protruding from the second display portion (312). The second portion (332b) protruding from the second display portion (312) can reduce the inflow of a material before curing into the flexible display (310) during the process of forming the resin portion (423). For example, the resin portion (423) can include a cured-in place gasket (CIPG) including butyl rubber, ethylene propylene diene monomer (EPDM), and / or polyurethane. The second waterproof structure (420) can have a closed-loop shape formed by the second waterproof tape (421), the third waterproof tape (422), and the resin portion (423). By forming a second waterproof space (S2) by a second waterproof structure (420) having a closed loop shape, damage to the flexible display (310) can be reduced.
[0129] FIG. 9 is an enlarged view of a portion of a display device according to various embodiments.
[0130] Referring to FIG. 9, the second layer (330) may include a waterproof member (332). For example, the waterproof member (332) may be disposed on the second polymer film (3112).
[0131] For example, the shielding member (331) may be positioned between the second magnet (M2) and the portion of the second display portion (312) positioned above the second magnet (M2) (e.g., in the +z direction). Compared to the structure illustrated in FIG. 6b, the structure illustrated in FIG. 9 may have the shielding member (331) positioned outside the second display portion (312).
[0132] For example, the thickness of the second layer (330) can be reduced by the shielding member (331) being disposed between the second display portion (312) and the second magnet (M2) rather than within the second layer (330). For example, the thickness of the waterproof member (332) can be about 80 um to about 100 um. For example, the thickness of the adhesive member (333) for attaching the waterproof member (332) to the first layer (320) (e.g., the electromagnetic induction panel (321)) can be about 20 um to about 30 um. For example, the thickness of the support member (334) interposed between the first layer (320) and the waterproof member (332) can be about 20 um to about 30 um. The thickness of the second layer (330) can be about 100 um to 130 um. Since the thickness of the second layer (330) illustrated in FIG. 6b is about 107 μm, the thickness of the second layer (330) can be made relatively thinner by placing the shielding member (331) outside the second display portion (312). As the thickness of the second layer (330) becomes relatively thinner, the curvature of the third display portion (313) can be reduced, and the thickness of the display device (300) and the foldable electronic device (101) can be reduced. The shielding member (331) can be fixed by being attached to the second display portion (312) under the second display portion (312). The shielding member (331) may not be attached to the second frame (227), but is not limited thereto.
[0133] According to an exemplary embodiment, a foldable electronic device is provided. The foldable electronic device may include a housing, a flexible display, a first layer, a second layer, a first magnet, and a second magnet. The housing may include a first housing part and a second housing part configured to rotate relative to the first housing part about a folding axis. The flexible display may include a first display portion, a second display portion, and a third display portion. The first display portion may include an active area forming at least a portion of a front surface of the housing. The second display portion may be opposite the first display portion. The second display portion may be spaced apart from the first display portion. The third display portion may connect the first display portion and the second display portion. The third display portion may be bendable. The first layer may include an electromagnetic induction panel disposed below the first display portion.
