[0041] The above and other aspects, features and advantages of the present disclosure will become apparent from the following description of the embodiments given in conjunction with the accompanying drawings. However, the present disclosure is not limited to the embodiments disclosed herein and may be implemented in various different forms. Herein, embodiments are provided to provide a complete disclosure of the present disclosure and to provide a thorough understanding of the present disclosure to those skilled in the art to which the present disclosure belongs, and the scope of the present disclosure shall be limited only by the attached claims and their equivalents. The same reference numerals always refer to the same elements.

[0042] When an element or layer is referred to as being associated with another element or layer (such as “on” another element or layer), the element or layer may be directly on the other element or layer, or intervening elements or layers may be present. Conversely, when an element or layer is referred to as being associated with another element or layer (such as “directly on” another element or layer), there are no intervening elements or layers.

[0043] The term used herein is only used to describe the purpose of a particular embodiment, and is not intended to be limited. Unless the context clearly indicates otherwise, as used herein, "one", "one (kind / person)", "described (the)" and "at least one (kind / person)" do not indicate the limitation of quantity, and are intended to include both the singular and the plural. Therefore, the reference to "described" element after the reference to "one" element in the claim includes one element and multiple elements. For example, unless the context clearly indicates otherwise, "an element" has the same meaning as "at least one element". "At least one (kind / person)" should not be interpreted as limiting "one" or "one (kind / person)". "Or" means "and / or". As used herein, the term "and / or" includes all combinations of each of the items mentioned and one or more items. It will also be understood that the terms “comprises and / or comprising” or “includes and / or including” when used in the specification specify the presence of stated features, regions, integers, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, components and / or groups thereof.

[0044] Spatially relative terms (such as "below", "beneath", "below", "above", and "on") may be used to easily describe the relationship between one element or component and another element or component as shown in the drawings. Spatially relative terms should be understood as terms that also include different orientations of an element during use or operation in addition to the orientation shown in the drawings.

[0045] Although the terms "first" and "second" and the like are used herein to describe various elements, components and / or sections, these elements, components and / or sections should not be limited by these terms. These terms are only used to distinguish one element, component or section from another element, component or section. Therefore, within the spirit and scope of the present disclosure, the first element, first component or first section mentioned below may be referred to as the second element, second component or second section.

[0046] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as those commonly understood by those skilled in the art to which the present disclosure belongs. It will also be understood that, unless expressly defined as such herein, terms (such as those defined in general dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and the context of the present disclosure, and should not be interpreted in an idealized or overly formal sense.

[0047] Embodiments are described herein with reference to cross-sectional views of the illustrations as idealized embodiments. As such, variations in the shapes of the illustrations due to, for example, manufacturing techniques and / or tolerances are anticipated. Therefore, the embodiments described herein should not be construed as being limited to the shapes of specific regions as shown herein, but rather to include deviations in shapes, for example, caused by manufacturing. For example, a region shown or described as flat may typically have rough and / or nonlinear features. Moreover, the sharp corners shown may be rounded. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to illustrate the precise shapes of the regions, and are not intended to limit the scope of the claims.

[0048] The embodiments described herein will be described with reference to plan views and cross-sectional views as ideal schematic diagrams of the present disclosure. Therefore, the form of the diagrams may change depending on the manufacturing technology and / or allowed errors. The embodiments of the present disclosure are not limited to the specific forms shown, but include changes in the form generated according to the manufacturing process. The areas shown in the drawings have schematic characteristics, and the shapes of the areas shown in the drawings illustrate specific forms of the areas of the device and are not intended to limit the scope of the present disclosure.

[0049] Hereinafter, embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings.

[0169] The fourth adhesive layer AL4 may be disposed between the electronic panel EP and the panel protection layer PPL. The electronic panel EP and the panel protection layer PPL may be bonded to each other through the fourth adhesive layer AL4.

[0170] The fifth adhesive layer AL5 may be disposed between the panel protection layer PPL and the barrier layer BRL. The panel protection layer PPL and the barrier layer BRL may be bonded to each other through the fifth adhesive layer AL5.

Specifically, the support plate PLT may be disposed under the barrier layer BRL, and the sixth adhesive layer AL6 may be disposed between the barrier layer BRL and the support plate PLT. The barrier layer BRL and the support plate PLT may be bonded to each other through the sixth adhesive layer AL6.

[0172] The sixth adhesive layer AL6 may overlap the first non-folding area NFA1a and the second non-folding area NFA2a, and may not overlap the folding area FAa. That is, the sixth adhesive layer AL6 may not be disposed in the folding area FAa. The sixth adhesive layer AL6 may define an adhesive opening portion (e.g., a gap) therein at the folding area FAa. The sixth adhesive layer AL6 may be disconnected at the folding area FAa.

[0173] The first to sixth adhesive layers AL1 to AL6 may include a transparent adhesive such as a pressure sensitive adhesive (PSA) or an optically clear adhesive (OCA). However, the type of the adhesive is not limited thereto.

[0174] The thickness of the panel protection layer PPL may be less than the thickness of the window protection layer WP, and the thickness of the barrier layer BRL may be less than the thickness of the panel protection layer PPL. The thickness of the electronic panel EP may be less than the thickness of the barrier layer BRL and may be equal to the thickness of the window WIN.

[0175] The thickness of the first adhesive layer AL1 may be equal to that of the barrier layer BRL, and the thickness of the second adhesive layer AL2 and the thickness of the third adhesive layer AL3 may each be equal to that of the panel protection layer PPL. The thickness of the fourth adhesive layer AL4 may be equal to that of the fifth adhesive layer AL5.

[0176] The thickness of the fourth adhesive layer AL4 and the thickness of the fifth adhesive layer AL5 may each be less than the thickness of the electronic panel EP, and may each be greater than the thickness of the impact absorbing layer ISL. The thickness of the sixth adhesive layer AL6 may be less than the thickness of the impact absorbing layer ISL. The thickness of the hard coating layer HC may be less than the thickness of the sixth adhesive layer AL6.

[0177] Along the planar direction, the electronic panel EP, the impact absorbing layer ISL, the panel protection layer PPL, and the third adhesive layer AL3 and the fourth adhesive layer AL4 may have the same width. The window protection layer WP and the first adhesive layer AL1 may have the same width. Due to the same width, the corresponding side surfaces of the layers may be at substantially the same position along the planar direction. In an embodiment, at the same side of the display device DD, the corresponding side surfaces of the layers may be coplanar with each other (such as being considered to have the same width), but are not limited thereto.

[0178] The width of the electronic panel EP, the impact absorbing layer ISL, the panel protective layer PPL, and the third adhesive layer AL3 and the fourth adhesive layer AL4 along the first direction DR1 may be greater than the width of the window protection layer WP and the first adhesive layer AL1 along the first direction DR1. The periphery of the electronic panel EP, the impact absorbing layer ISL, the panel protective layer PPL, and the third adhesive layer AL3 and the fourth adhesive layer AL4 may be disposed outside the periphery of the window protection layer WP and the first adhesive layer AL1. That is, the electronic panel EP, the impact absorbing layer ISL, the panel protective layer PPL, and the third adhesive layer AL3 and the fourth adhesive layer AL4 may extend farther than the side surface of the window protection layer WP and the side surface of the first adhesive layer AL1.

[0179] The width of the window WIN along the first direction DR1 may be greater than the width of the electronic panel EP, the impact absorbing layer ISL, the panel protection layer PPL, and the third and fourth adhesive layers AL3 and AL4 in the first direction DR1. Fig. 9AAt the right side of the window WIN, the periphery of the window WIN may be disposed outside the peripheries of the electronic panel EP, the impact absorbing layer ISL, the panel protection layer PPL, and the third and fourth adhesive layers AL3 and AL4.

[0180] The width of the second adhesive layer AL2 in the first direction DR1 may be smaller than the widths of the window protection layer WP and the first adhesive layer AL1 in the first direction DR1. The periphery of the second adhesive layer AL2 may be disposed inside the peripheries of the window protection layer WP and the first adhesive layer AL1. That is, one or more of the plurality of side surfaces of the second adhesive layer AL2 may be recessed from the corresponding side surfaces of the window protection layer WP and the first adhesive layer AL1.

[0181] The barrier layer BRL and the fifth and sixth adhesive layers AL5 and AL6 may have a width along the first direction DR1 smaller than that of the second adhesive layer AL2. The periphery of the barrier layer BRL and the fifth and sixth adhesive layers AL5 and AL6 may be disposed inside the periphery of the second adhesive layer AL2.

[0182] The support plate PLT may be disposed under the display unit DSP and may support the display unit DSP. The support plate PLT may be disposed under the electronic panel EP and may support the electronic panel EP. The support plate PLT may have higher rigidity than the display unit DSP.

[0183] The support plate PLT may include a non-metal material. For example, the support plate PLT may include a fiber-reinforced composite material. The fiber-reinforced composite material may be a carbon fiber reinforced plastic (CFRP) or a glass fiber reinforced plastic (GFRP).

[0184] The support plate PLT including the fiber reinforced composite material can be made relatively light. The support plate PLT including the fiber reinforced composite material can be lighter than a metal support plate formed of a metal material, and can have a modulus (eg, elastic modulus) and stiffness similar to those of a metal support plate.

[0185] In addition, the support plate PLT including the fiber reinforced composite material can be easily shaped than the metal support plate. For example, the support plate PLT including the fiber reinforced composite material can be easily shaped by a laser process or a micro sandblasting process.

[0186] However, this is illustrative and not limited thereto, and the support plate PLT may include a metal material.

[0187] The support plate PLT may include a first non-folding portion PLT1, a folding portion PLF, and a second non-folding portion PLT2. The first non-folding portion PLT1 may overlap with the first non-folding area NFA1a. The folding portion PLF may overlap with the folding area FAa. The second non-folding portion PLT2 may overlap with the second non-folding area NFA2a.

[0188] The support plate PLT may have a plurality of openings OP defined therein at the folding portion PLF. The openings OP (e.g., plate openings) may be formed in the third direction DR3 to pass through a thickness portion of the support plate PLT. When viewed in the second direction DR2, the openings OP may be arranged in the first direction DR1 so as to be spaced apart from each other, with the plate openings between the openings OP. The openings OP may be formed (or provided) by the above-mentioned laser process or micro-sandblasting process. Based on the first direction DR1, the width of the openings OP may be smaller than the width of the adhesive opening portion of the sixth adhesive layer AL6.

[0189] Since the opening OP is defined in the portion of the support plate PLT overlapping the folding area FAa, the flexibility of the support plate PLT overlapping the folding area FAa (eg, the folding portion PLF) can be increased. Therefore, the support plate PLT can be folded around the folding area FAa.

[0190] The folding portion PLF may include a branch portion BR. Each of the plurality of branch portions BR may be disposed between openings OP adjacent to each other in the first direction DR1. The branch portion BR may be a material portion (or a solid portion) of the support plate PLT, and a gap corresponding to the opening OP may be defined by the branch portion BR. In an embodiment, the opening OP may be defined along the entire thickness portion of the support plate PLT at the folding area FAa (such as being open at the upper surface of the support plate PLT closest to the electronic panel EP and at the lower surface of the support plate PLT farthest from the electronic panel EP).

[0191] Although not shown, the display device DD may further include a digitizer, a shielding layer, and a heat radiation layer disposed under the support plate PLT.

[0192] Reference Fig. 9B The panel protection layer PPL and the fourth adhesive layer AL4 may not be disposed under the bending portion BA of the electronic panel EP. The panel protection layer PPL and the fourth adhesive layer AL4 may be disposed under the first panel portion AA1 of the electronic panel EP. The data driver DDV may be disposed under the second panel portion AA2 of the electronic panel EP.

[0193] The printed circuit board PCB may be connected to the electronic panel EP at the second panel portion AA2. The printed circuit board PCB may be connected to a side of the second panel portion AA2, wherein the side is farthest from the first panel portion AA1. As the display module DM is bent at the bending portion BA, the second panel portion AA2 may be disposed under the first panel portion AA1. Therefore, the data driver DDV and the printed circuit board PCB may be disposed under the first panel portion AA1 to face the first panel portion AA1 along the thickness direction of the folded display module DM.

[0194] Fig.10 It is along Figure 7 A cross-sectional view taken along line VI-VI' shown in FIG.

[0195] Fig.10 is a view showing a portion of the display unit DSP, a portion of the support panel PLT, and a portion of the window module WM.

[0196] Fig.10 is a cross-sectional view of the display device DD viewed in the first direction DR1.

Fig. 9A The window module WM, display unit DSP and support plate PLT shown in FIG. 1 are substantially the same. Therefore, the following description will focus on Fig.10 The display device DD and Fig. 9A The differences between the display devices DD are shown in FIG.

[0198] Reference Fig.10 , the electronic panel EP, the impact absorbing layer ISL, the panel protection layer PPL, the third and fourth adhesive layers AL3 and AL4, and the support plate PLT may have the same width as each other.

[0199] The window WIN, the window protection layer WP, the first adhesive layer AL1 and the hard coating layer HC may have the same width.

[0200] The barrier layer BRL and the fifth and sixth adhesive layers AL5 and AL6 may have the same width.

[0201] The width of the window module WM in the second direction DR2 may be greater than the width of the display module DM in the second direction DR2. The periphery of the window WIN, the window protection layer WP, the first adhesive layer AL1, and the hard coating layer HC may be disposed outside the periphery of the electronic panel EP, the impact absorbing layer ISL, the panel protection layer PPL, the third adhesive layer AL3, the fourth adhesive layer AL4, and the support plate PLT in the second direction DR2.

[0202] The display module DM and the support plate PLT may have substantially the same width in the second direction DR2. The width of the second adhesive layer AL2 may be smaller than the width of the display module DM and the support plate PLT. The periphery of the second adhesive layer AL2 may be disposed inside the periphery of the electronic panel EP, the impact absorbing layer ISL, the panel protection layer PPL, the third adhesive layer AL3 and the fourth adhesive layer AL4, and the support plate PLT.

[0203] The width of the barrier layer BRL and the fifth and sixth adhesive layers AL5 and AL6 may be smaller than the width of the display module DM and the support plate PLT. The periphery of the barrier layer BRL and the fifth and sixth adhesive layers AL5 and AL6 may be disposed inside the periphery of the display module DM and the support plate PLT.

[0204] The width of the second adhesive layer AL2 may be smaller than the widths of the barrier layer BRL and the fifth and sixth adhesive layers AL5 and AL6. The periphery of the second adhesive layer AL2 may be disposed inside the peripheries of the barrier layer BRL and the fifth and sixth adhesive layers AL5 and AL6.

[0205] Fig.11 It is along Figure 1A An enlarged cross-sectional view taken along line II' shown in FIG.

[0206] Fig.11 The structure of the electronic device EDa at a first edge portion viewed in the second direction DR2 is shown.

[0207] Fig.11 is a view showing the electronic device EDa in an unfolded state, the electronic device EDa having the display device DD bent inside the electronic device EDa.

[0208] Fig.11 The window module WM, display unit DSP and support plate PLT Fig. 9A and Fig. 9B The window module WM, the display unit DSP, and the supporting panel PLT shown in FIG. 1 are the same and thus will be omitted from the description or will be briefly described.

[0209] Reference Figure 3 and Fig.11 , the first molding part MP1 as the first molding member may be disposed on one side of the display device DD along the first direction DR1. The first molding part MP1 may be disposed on one side of the support plate PLT and one side of the display unit DSP corresponding to each other (for example, at the same side of the electronic device EDa). The first molding part MP1 may be disposed under the window WIN (specifically, the first molding part MP1 may be disposed between the window WIN and the display unit DSP). Figure 3The first molding part MP1 may cover the second panel portion AA2 overlapping the first panel portion AA1. One side of the display unit DSP may be parallel to the folding axis FXa (refer to Figure 1A ) and the side adjacent to the bending portion BA.

[0210] As used herein, "one side" may be considered to be an outer side surface or an end surface of a corresponding layer. Fig.11 The first molding part MP1 may cover one side of the support plate PLT, one side of the display unit DSP, and the bent portion BA of the display module DM bent at the bent portion BA. The first molding part MP1 may fix the positions of the support plate PLT, the display unit DSP, and the bent portion BA in the unfolded (or flat) form of the electronic device EDa.

[0211] Therefore, when the electronic device EDa is folded relative to the unfolded form, the first molding part MP1 can prevent the edges (e.g., outer edges or side surfaces) of the display module DM, the panel protection layer PPL, the fifth adhesive layer AL5, the barrier layer BRL, the sixth adhesive layer AL6 and the support plate PLT from moving or sliding at the first edge portion.

[0212] The bracket EDC may include a first bracket BR1 and a second bracket BR2. The first bracket BR1 may be disposed under the display device DD. The first bracket BR1 and the second bracket BR2 may represent Figure 3 The first housing EDC1 shown in FIG. 8 may include a display device DD and a first molding part MP1 disposed on an upper surface BR1 -U1 of the first bracket BR1 .

The first corner EG1 may be defined as a point of the second bracket BR2 having a maximum height from the upper surface BR1-U1 of the first bracket BR1 in the third direction DR3. The outer surface of the second bracket BR2 may be defined as a surface facing away from the display device DD. The outer surface of the second bracket BR2 may define the outer surface of the electronic device EDa at its first edge portion.

[0215] The first receiving groove GR1 may be defined by the upper surface BR1-U1 of the first bracket BR1 and a portion of the inner surface of the second bracket BR2. The first receiving groove GR1 may extend between the protrusion BPP and the second bracket BR2. The inner surface of the second bracket BR2 may be defined as a surface facing the display device DD and opposite to the outer surface of the second bracket BR2.

[0216] A portion of the window WIN may be disposed in the first receiving groove GR1. An outer periphery of the window WIN may be disposed in the first receiving groove GR1. A portion of the window WIN overlapping the second bracket BR2 may be defined as a first portion (or first window part) PT1.

[0217] The end of the window WIN may be bent into a curved shape. The bent end of the window WIN may be disposed in the first receiving groove GR1 in a curved shape. The first portion PT1 may be disposed in the first receiving groove GR1 in a curved shape. The first portion PT1 may extend along the second bracket BR2 along the first direction DR1 and extend into the first receiving groove GR1. The first portion PT1 may be adjacent to the bent portion BA.

[0218] The first adhesive layer AL1, the window protection layer WP, and the hard coating layer HC of the window module WM may not be disposed in the first receiving groove GR1. The first adhesive layer AL1, the window protection layer WP, and the hard coating layer HC may not overlap with the second bracket BR2. Due to not being disposed or not overlapping, the elements may be spaced apart from each other or adjacent to each other along the plane direction.

[0219] The bracket EDC may include a protrusion BPP. The protrusion BPP may be provided to protrude from a virtual plane corresponding to the upper surface BR1-U1 of the first bracket BR1. The protrusion BPP may extend from the upper surface BR1-U1 of the first bracket BR1 in the third direction DR3. Basically, the protrusion BPP may be formed integrally with the first bracket BR1. That is, the protrusion BPP and / or the second bracket BR2 may be a single integral body with the first bracket BR1.

[0220] For example, when viewed in the second direction DR2, the protrusion BPP may have a triangular cross-sectional shape. However, not limited thereto, the protrusion BPP may have various shapes. The opposite side surfaces of the protrusion BPP facing each other in the first direction DR1 may be inclined. The extending directions of the inclined surfaces may be opposite to each other.

[0221] The first adhesive part GRP1 may be disposed between the first side surface of the protrusion BPP and the first portion PT1 of the window WIN. A portion of the first adhesive part GRP1 may be attached to the first portion PT1 at the lower surface of the first adhesive part GRP1. Another portion of the first adhesive part GRP1 may be attached to one of a plurality of opposite side surfaces of the protrusion BPP that are opposite to each other in the first direction DR1. One side surface of the protrusion BPP may be defined as a side surface that is opposite to the other side surface of the first molding part MP1. The first portion PT1 and the protrusion BPP may be bonded to each other by the first adhesive part GRP1 as a first adhesive member. The bent state of the first portion PT1 may be maintained by the first adhesive part GRP1.

[0222] Fig.12 It is along Figure 1A An enlarged cross-sectional view taken along line II-II' shown in FIG.

[0223] Fig.12 The structure of the electronic device EDa at the second edge portion viewed in the second direction DR2 is shown.

[0224] Fig.12 is a view showing the electronic device EDa in an unfolded state, the electronic device EDa having a plurality of electronic devices (for example, Fig.11 A display device DD is bent at a first edge portion as shown in FIG.

[0225] Fig.12 The window module WM, display unit DSP and support plate PLT Fig. 9A and Fig. 9B The window module WM, the display unit DSP, and the supporting panel PLT shown in FIG. 1 are the same and thus will be omitted from the description or will be briefly described.

[0226] Reference Figure 3 and Fig.12 The second molding part MP2 as the second molding member may be disposed on the opposite side of the display device DD along the first direction DR1. The opposite side of the display device DD may be defined as a portion of the display device DD parallel to the folding axis FXa (refer to FIG. Figure 1A) on one side opposite to the side adjacent to the bending portion BA. The second molding part MP2 can be arranged on the opposite side of the fifth adhesive layer AL5, the opposite side of the barrier layer BRL, the opposite side of the sixth adhesive layer AL6, and the opposite side of the support plate PLT corresponding to each other (for example, can be arranged at the same side of the electronic device EDa). The second molding part MP2 can cover the opposite side of the fifth adhesive layer AL5, the opposite side of the barrier layer BRL, the opposite side of the sixth adhesive layer AL6, and the opposite side of the support plate PLT. The opposite side of the fifth adhesive layer AL5, the opposite side of the barrier layer BRL, the opposite side of the sixth adhesive layer AL6, and the opposite side of the support plate PLT can be defined as a side facing the third bracket BR3 to be described below. The second molding part MP2 can protect the support plate PLT, the barrier layer BRL, and the fifth adhesive layer AL5 and the sixth adhesive layer AL6 from moisture or foreign matter.

[0227] The first bracket BR1 as a first bracket portion may be disposed under the electronic panel EP. The upper surface BR1-U of the first bracket BR1 may include an upper surface 1-1BR1-U1 as a first upper surface portion (also referred to as upper surface BR1-U1) and an upper surface 1-2BR1-U2 as a second upper surface portion (also referred to as upper surface BR1-U2). Fig.11 ) can be considered as a part of the first upper surface portion, but is not limited to this. The upper surface 1-1BR1-U1 and the upper surface 1-2BR1-U2 can be arranged in different planes, and the step is between the upper surface 1-1BR1-U1 and the upper surface 1-2BR1-U2. Relative to the lower surface defined by the first bracket BR1 such as the bracket EDC, the upper surface 1-1BR1-U1 can be positioned at a higher position than the upper surface 1-2BR1-U2. Since the upper surface 1-1BR1-U1 and the upper surface 1-2BR1-U2 are arranged to have a step between the upper surface 1-1BR1-U1 and the upper surface 1-2BR1-U2, the receiving groove 2-1GR2-1 (also referred to as the receiving groove GR2-1) can be defined as a recess by the first bracket BR1.

[0228] The bracket EDC may further include a third bracket BR3. The third bracket BR3 may be arranged to extend from a virtual plane corresponding to the upper surface 1-2BR1-U2 toward the window WIN and cover the second portion PT2. The third bracket BR3 may extend from the upper surface 1-2BR1-U2 in a third direction DR3. When viewed in the second direction DR2, a portion of the third bracket BR3 may have a curved shape. Although not shown, the third bracket BR3 and the second bracket BR2 (refer to Fig.11) may be disposed on opposite sides of the first bracket BR1 that are opposite to each other in the first direction DR1. That is, the second bracket BR2 and the third bracket BR3 may be spaced apart from each other in the first direction DR1.

[0229] The second corner EG2 of the third bracket BR3 may be positioned at a higher position than the upper surface of the hard coating layer HC. The third bracket BR3 may overlap the hard coating layer HC, but the second bracket BR2 is adjacent to the end of the hard coating layer HC so as not to overlap the hard coating layer HC. The second corner EG2 may be defined as a point having a maximum height from the upper surface 1-1BR1-U1 of the first bracket BR1 to the outer surface of the third bracket BR3 in the third direction DR3. The outer surface of the third bracket BR3 may be defined as a surface opposite to the surface of the third bracket BR3 facing the display device DD.

[0230] The receiving groove 2-2GR2-2 (also referred to as the receiving groove GR2-2) may be formed by the inner surface of the third bracket BR3. The inner surface of the third bracket BR3 may be defined as a surface facing the display device DD. Basically, the receiving groove 2-2GR2-2 may be defined integrally with the receiving groove 2-1GR2-1 (such as forming a single receiving space). That is, the second receiving groove GR2 may be defined at the inner surfaces of both the first bracket BR1 and the third bracket BR3 together with the layers in the receiving space.

[0231] The display device DD and the second molding part MP2 may be accommodated in the bracket EDC. The support plate PLT may be disposed on the upper surface 1-1BR1-U1 of the first bracket BR1. The second molding part MP2 may be disposed on the upper surface 1-1BR1-U1 of the first bracket BR1.

[0232] When the display device DD is disposed on the upper surface 1-1BR1-U1 of the first bracket BR1, a portion of the window module WM and a portion of the display module DM may be disposed in the second receiving groove GR2. A portion of the window module WM and a portion of the display module DM may be disposed in the receiving groove 2-2GR2-2. The periphery of the window module WM and the display module DM that extends farther than the side surfaces of various other (modules) may be disposed in the receiving groove 2-2GR2-2. The portion of the window WIN that overlaps with the third bracket BR3 may be defined as a second portion (or second window portion) PT2. The second portion PT2 may overlap with the third bracket BR3 along the first direction DR1. Fig.11 The second portion PT2 may extend along the third bracket BR3 and extend into the second receiving groove GR2.

[0233] The portion of the window module WM extending into the second receiving groove GR2 and the portion of the display module DM extending into the second receiving groove GR2 may be bent into a curved shape. A portion of the window module WM and a portion of the display module DM may be disposed in the receiving groove 2-2GR2-2 in a curved shape. The second portion PT2 may be disposed in the receiving groove 2-2GR2-2 in a curved shape.

[0234] The electronic device EDa may further include a guide member GPa as a guide for the display device DD. The guide member GPa may be disposed between the first bracket BR1 and the lower surface of the display module DM (such as the panel protection layer PPL). A portion of the guide member GPa may be disposed on the upper surface BR1-U1 of the first bracket BR1. For example, another portion of the guide member GPa may be disposed on the lower surface of the panel protection layer PPL.

[0235] The guide member GPa may include a track CT and a wheel WH, the wheel WH being disposed inside the track CT bent into a curved shape. A portion of the track CT may be disposed on and extend along the upper surface BR1-U1 of the first bracket BR1, and another portion of the track CT may be disposed on and extend along the lower surface of the display module DM.

[0236] The track CT may include a first track portion CT1 between the wheel WH and the first bracket BR1, a bent track portion CBT, and a second track portion CT2 between the wheel WH and the window WIN. The first track portion CT1 may be defined as a portion of the track CT extending along the upper surface BR1-U1 of the first bracket BR1. The second track portion CT2 may be defined as a portion of the track CT facing the first track portion CT1 and extending along the lower surface of the display module DM. The bent track portion CBT may be defined as a portion of the track CT that is bent and connects the first track portion CT1 and the second track portion CT2 to each other.

[0237] When viewed in the second direction DR2, the first rail portion CT1 may be shorter than the second rail portion CT2 in a direction along the corresponding components (e.g., the display module DM and the first bracket BR1). However, not limited thereto, the first rail portion CT1 may have the same length as the second rail portion CT2, or the first rail portion CT1 may be longer than the second rail portion CT2. Fig.13A and Fig. 13B A detailed description is given thereon.

[0238] Each of the first track portion CT1, the second track portion CT2, and the curved track portion CBT may include a track protrusion PRP. The track protrusion PRP may be provided on virtual surfaces of the first track portion CT1 and the second track portion CT2 facing each other or protrude from virtual surfaces of the first track portion CT1 and the second track portion CT2 facing each other. The track protrusion PRP may be provided on a surface of the curved track portion CBT facing the wheel WH.

[0239] The wheel WH may be disposed between the first track portion CT1 and the second track portion CT2. The wheel WH and the curved track portion CBT may be arranged in the first direction DR1, and the curved track portion CBT is closer to the second end of the electronic device EDa than the wheel WH. The wheel WH may be differently engaged with the first track portion CT1, the second track portion CT2, and the curved track portion CBT.

[0240] The wheel protrusions PRG may be provided along the outer surface of the wheel WH. The wheel protrusions PRG may be spaced apart from each other at predetermined intervals along the outer surface of the wheel WH. The track protrusions PRP of the first track portion CT1, the second track portion CT2, and the bent track portion CBT may be engaged differently with the wheel protrusions PRG. Therefore, when the track protrusions PRP move along the outer surface of the wheel WH, the wheel WH may rotate about a rotation axis parallel to the second direction DR2. This will be referred to later. Fig.13A and Fig. 13B A detailed description is given thereon.

[0241] In an embodiment, the wheel WH may be actively driven to rotate, and the friction between the rotating wheel WH and the display module DM may cause the display device DD to slide passively along a sliding direction (e.g., a first direction DR1). In an embodiment, the active sliding of the display module DM may cause the wheel WH to rotate passively and allow the display device DD to slide in the sliding direction.

[0242] The electronic device EDa may further include a tip portion TP. The tip portion TP may be disposed on an inner surface of the third bracket BR3. The tip portion TP may extend from the inner surface of the third bracket BR3 in a direction toward the hard coating layer HC. The tip portion TP may be disposed adjacent to an upper portion of the third bracket BR3. The inner surface of the third bracket BR3 may be defined as a surface facing the display device DD.

[0243] For example, the tip portion TP may include an elastic material. Fig.12 As shown in , the distal end of the tip portion TP may contact the hard coating layer HC. When in contact, the elements may form an interface therebetween. The tip portion TP may be disposed between the third bracket BR3 and the hard coating layer HC, and may block foreign matter introduced into the second receiving groove GR2 from the outside of the electronic device EDa.

[0244] However, without limitation thereto, the tip portion TP may be spaced apart from the hard coating layer HC by a predetermined distance. The distance between the tip portion TP and the hard coating layer HC may be adjusted according to the size of the foreign matter. The distance may be defined at a position along the upper surface of the hard coating layer HC facing the inner surface of the third bracket BR3 (such as in a direction normal to the upper surface).

[0245] Although it has been described that the tip portion TP includes an elastic material, the present disclosure is not limited thereto, and the tip portion TP may be a non-elastic body. The tip portion TP may include metal or plastic. In this case, the tip portion TP may be spaced apart from the hard coating layer HC by a predetermined distance.

[0246] Fig.13A and Fig. 13B It is along Figure 1B A cross-sectional view taken along line IV-IV' shown in FIG. Fig.13A yes Fig.11 A view of the structure in which the structure is flipped and faces Fig.12 The structure in Figure 1B At the second edge portion of the folded electronic device EDa. Fig.14 is a cross-sectional view of an electronic device according to a comparative example.

[0247] Fig.13A and Fig. 13B 1 is a view of a corresponding edge portion of an electronic device EDa in a folded state, the electronic device EDa having a display device DD bent within the electronic device EDa (eg, referring to Fig.12 ).Although Fig.13A and Fig. 13B The views in are shown separately for illustration, but it will be understood that Fig.13A and Fig. 13B The structure can be found in Figure 1B The second edge portions of the folded electronic devices EDa are directly adjacent to each other.

[0248] Fig.14 is a diagram showing the electronic device EDa' and Fig. 13B A view of a second edge portion corresponding to the third bracket BR3.

[0249] Fig.14 is a cross-sectional view corresponding to the opposite side of the electronic device EDa′ (eg, at the second edge portion) according to the comparative example.

[0250] right Fig.14 The description of the electronic device EDa' shown in FIG. 1 will focus on the Fig. 13B The difference between the electronic device EDa shown in FIG.

[0251] Fig.13A and Fig. 13B The display device DD, the first bracket BR1, the second bracket BR2, the third bracket BR3, the guide part GPa, the first molding part MP1, the second molding part MP2 and the first adhesive part GRP1 are Fig.11 and Fig.12 The display device DD, the first bracket BR1, the second bracket BR2, the third bracket BR3, the guide part GPa, the first molding part MP1, the second molding part MP2, and the first adhesive part GRP1 are the same and thus will be omitted from the description or will be briefly described.

[0252] Reference Figure 1A , Figure 1B and Fig. 13B The third area FAa of the electronic device EDa may be folded about a folding axis FXa extending in the second direction DR2. When the electronic device EDa is folded at the third area FAa, the electronic device EDa may be folded inwardly so that the first area NFA1a and the second area NFA2a face each other.

[0253] When the electronic device EDa is folded, the first corner EG1 (for example, Fig.13A ) and the second corner EG2 may face each other at a second edge portion of the electronic device EDa. Figure 1A In the electronic device EDa that is unfolded as in FIG. 1 , the height of the first corner EG1 and the height of the second corner EG2 may each be greater than the height of the upper surface of the hard coating layer HC. Figure 1B When folded as in FIG. 1 , the first corner EG1 and the second corner EG2 may contact each other before the portion of the upper surface of the hard coating layer HC overlapping the first display area DAa1 and the portion of the upper surface of the hard coating layer HC overlapping the second display area DAa2 contact each other. Fig.13A and 13B As shown in the view of the stacking structure at the second edge portion of the folded electronic device EDa, the bracket EDC (refer to Figure 3 ) are closer to each other along the third direction DR3 than the closest corresponding parts of the hard coating layer HC. Therefore, when the electronic device EDa is folded, damage to the hard coating layer HC can be prevented.

[0254] The display device DD (for example, see Fig.12 ) with the second bracket BR2 (for example, refer to Fig.13A ) adjacent to one side (eg, at the first edge portion) may be formed by the first molding member MP1 (eg, referring to Fig.13A) is fixed. Therefore, when the electronic device EDa is folded, the periphery of the window module WM, the display module DM, the panel protection layer PPL, the fifth adhesive layer AL5, the barrier layer BRL, the sixth adhesive layer AL6 and the support plate PLT can be fixed in place without moving or sliding.

[0255] When the electronic device EDa is folded, sliding may occur on the opposite side of the display device DD adjacent to the third bracket BR3 (e.g., at the second edge portion). The periphery of the window module WM, the display module DM, the panel protection layer PPL, the fifth adhesive layer AL5, the barrier layer BRL, the sixth adhesive layer AL6, and the support plate PLT may move or slide. That is, the second end (e.g., periphery) of the window module WM, the display module DM, the panel protection layer PPL, the fifth adhesive layer AL5, the barrier layer BRL, the sixth adhesive layer AL6, and the support plate PLT can move or slide relative to the bracket EDC.

[0256] When the second ends (e.g., peripheries) of the window module WM, the display module DM, the fifth adhesive layer AL5, the barrier layer BRL, the sixth adhesive layer AL6, and the support plate PLT slide or move along the inner surface of the bracket EDC, the second end of the display module DM and the window module WM can be moved along the second receiving groove GR2 (e.g., along both the sliding direction and the thickness direction), the second end of the second part PT2 of the window WIN can be moved into the receiving groove 2-1GR2-1, and the area of ​​the second part PT2 overlapping with the third bracket BR3 can be increased. The display module DM and the window module WM can be in a bent state within the second receiving groove GR2 of the bracket EDC. Therefore, the sliding peripheries of the window module WM and the display module DM can be invisible to the user.

[0257] Reference Fig.14 When the electronic device EDa' according to the comparative example is folded, the second end (e.g., periphery) of the display device DD' may slide along the third bracket BR3'. The display device DD' may be disposed in a space defined by the first bracket BR1' and the third bracket BR3'. At this time, the periphery of the display device DD' may not be bent.

[0258] like Fig.14 As shown in , in order to prevent the sliding from being visible from the outside, the third bracket BR3' may have a flipped and inverted L-shape. In this case, a portion of the third bracket BR3' extending in the first direction DR1 may have a second length L2.

[0259] Reference Fig. 13B When the electronic device EDa is folded, the peripheries of the window module WM, the display module DM and the panel protection layer PPL can be disposed in the second receiving groove GR2 in a state of being bent in a curved shape to provide a bent display device DD (for example, referring to Fig.12 ).

[0260] According to one or more embodiments, the third bracket BR3 may overlap the periphery of the display device DD to prevent sliding from being visible from the outside. Even in the folded electronic device EDa, when viewed in the second direction DR2, the third bracket BR3 may have a first length L1 in the first direction DR1. The first length L1 may be smaller than the second length L2.

[0261] Reference Figure 1A , Figure 1B , Fig. 13B and Fig.14 ,because Fig.13A and Fig. 13B The display device DD (for example, see Fig.12 ) is arranged in the second receiving groove GR2 in a bent state, so the third bracket BR3 covering a portion of the display device DD can be shorter than the conventional bracket structure in the first direction DR1. Therefore, the plane area of ​​the display device DD overlapping with the third bracket BR3 (for example, defined in the DR1-DR2 plane) can be reduced. Therefore, the plane area of ​​the display surface DSa of the electronic device EDa can be increased. For example, the visible part of the display surface DSa is defined by the bracket EDC at the first corner EG1 and the second corner EG2 (refer to Figure 3 ) between the inner surfaces of the .

[0262] Reference Fig. 13B , when the display device DD (for example, referring to Fig.12 ) moves in a sliding direction (e.g., along the first direction DR1), the track CT attached to the lower surface of the panel protection layer PPL may be moved. The track CT may move together with the panel protection layer PPL and the layers attached thereto (e.g., the layers of the display device DD). In an embodiment, the track CT may be fixedly attached to the panel protection layer PPL at a position along the second track portion CT2. Fig.12 and Fig. 13B , the unattached portion of the track CT may extend from the fixed position in a direction toward the first track portion CT1. Fig.12 The unattached portion of the track CT at the second track portion CT2 in the panel protection layer PPL can be moved from the lower surface of the panel protection layer PPL and moved onto the upper surface BR1-U1 of the first bracket BR1 while traveling along the outer surface of the wheel WH to be included in Fig. 13B The first track portion CT1 may be disposed along the upper surface BR1-U1 of the first bracket BR1.

[0263] The rail protrusion PRP at the second rail portion CT2 of the rail CT can be moved while engaging with the wheel protrusion PRG provided on the surface of the wheel WH. When the electronic device EDa is folded, as the second rail portion CT2 moves around the wheel WH in the clockwise direction, the length of the first rail portion CT1 extending along the upper surface BR1-U1 of the first bracket BR1 can increase, and the length of the second rail portion CT2 extending along the lower surface of the panel protection layer PPL can decrease. In the folded electronic device EDa, the length of the first rail portion CT1 can be greater than the length of the second rail portion CT2.

[0264] The direction of movement of the display module DM and the window module WM can be adjusted by the guide member GPa connected to the display module DM and the window module WM. That is, since the guide member GPa is provided between the first bracket BR1 and the display module DM, the display module DM and the window module WM can be moved along the second receiving groove GR2 defined by the first bracket BR1 and the third bracket BR3 (for example, along both the sliding direction and the thickness direction). Therefore, the window module WM and the display module DM can be moved without separating the bracket EDC (refer to Figure 3 ). Therefore, the folding reliability of the electronic device EDa can be improved.

[0265] FIG. 15A to FIG. 15E is a cross-sectional view for explaining the second guide member GPb according to the embodiment of the present disclosure.

[0266] Fig.15A It is along Figure 1A A cross-sectional view taken along line II-II' shown in FIG. Fig. 15B and Fig. 15C yes Fig.15A A top plan view of the second guide member GPb shown in FIG. Fig.15D and Fig.15E It is along Figure 1B A cross-sectional view taken along line IV-IV' shown in FIG.

[0267] Fig.15A The electronic device EDa is shown in a deployed state, and Fig.15D and Fig.15E The electronic device EDa is shown in a folded state. Fig.15A ) and fold( Fig.15D and Fig.15E ) of the electronic device EDa, the display device DD at the first end ( Figure 1A line I-I' in) and the second end ( Figure 1A Line II-II' and Figure 1B Bend at line IV-IV'). Fig.15E yes Fig.11A view of the structure in which the structure is flipped and faces Fig.15A The structure in Figure 1B At the second edge portion of the folded electronic device EDa.

[0268] Fig.15A , Fig.15D and Fig.15E The display device DD, the first bracket BR1, the second bracket BR2, the third bracket BR3, the second molding part MP2, the first adhesive part GRP1 and the tip part TP are shown in FIG. Fig.13A and Fig. 13B The display device DD, the first bracket BR1, the second bracket BR2, the third bracket BR3, the second molding part MP2, the first adhesive part GRP1, and the tip portion TP are the same and thus will be omitted from the description or will be briefly described.

[0269] Reference Fig.15A , the second guide part GPb as a guide for the display device DD may be disposed between the first bracket BR1 and the display module DM. The second guide part GPb may be connected to the first bracket BR1. The second guide part GPb may be connected to the display module DM.

[0270] Reference FIG. 15A to FIG. 15C , the second guide part GPb may include a first guide plate GPT1 and a second guide plate GPT2. The first guide plate GPT1 may be connected to the first bracket BR1, and the second guide plate GPT2 may be connected to the display module DM. The first guide plate GPT1 may be fixedly connected to the first bracket BR1, and the second guide plate GPT2 may be fixedly connected to the display module DM and may be movable with the display module DM. The first guide plate GPT1 may be disposed on an upper surface BR1-U1 of the first bracket BR1. The second guide plate GPT2 may be disposed under the display module DM at a position where it overlaps with the second portion PT2. For example, the second guide plate GPT2 may be disposed on a lower surface of the panel protection layer PPL.

[0271] When viewed from above a plane (eg, a plan view of a DR1 - DR2 plane), the first guide plate GPT1 may have a shape of a portion of a rectangle. However, this is illustrative, and the first guide plate GPT1 may have various planar shapes.

[0272] The first guide plate GPT1 may have (or define) a plurality of guide grooves GR defined therein. The guide grooves GR may extend longitudinally in the first direction DR1 from one side of opposite sides of the first guide plate GPT1 facing each other in the first direction DR1 toward the other side. One side of the first guide plate GPT1 may be defined as a side facing the second guide plate GPT2.

[0273] The guide grooves GR may be spaced apart from each other in the second direction DR2. Fig. 15B and Fig. 15C Four guide grooves GR are shown in FIG. 4 , but the number of guide grooves GR may vary.

[0274] The second guide plate GPT2 may include a plurality of guide ribs GRB and a guide frame GFR. When viewed from above a plane, the guide frame GFR may have a rectangular shape extending longitudinally in the second direction DR2.

[0275] The guide rib GRB may be provided on one side of the guide frame GFR, which are opposite to each other in the first direction DR1. The guide rib GRB may extend from one side of the guide frame GFR in the first direction DR1. Basically, the guide rib GRB may be formed integrally with the guide frame GFR. One side of the guide frame GFR in the first direction DR1 may be defined as a side facing the first guide plate GPT1.

[0276] When viewed from above a plane, the plurality of guide ribs GRB may be arranged in the second direction DR2 so as to be spaced apart from each other in the second direction DR2. Fig. 15B and Fig. 15C Four guide ribs GRB are shown in FIG. 4 , but the present invention is not limited thereto, and the number of the guide ribs GRB may be varied to correspond to the number of the guide grooves GR.

[0277] When viewed from above in a plane, the guide rib GRB may have a planar shape corresponding to a planar shape of the first guide plate GPT1 at the guide groove GR For example, the guide rib GRB may have a rectangular shape.

[0278] The guide rib GRB can reciprocate along the sliding direction (for example, the first direction DR1) toward the inside or outside of the guide groove GR. That is, the first guide plate GPT1 and the second guide plate GPT2 can move relative to each other along the sliding direction. By inserting the guide rib GRB into the corresponding guide groove GR among the multiple guide grooves GR, or pulling the guide rib GRB out of the corresponding guide groove GR among the multiple guide grooves GR, the length portion of the guide rib GRB can be variable. The state in which substantially the entire length of the guide rib GRB is set in the guide groove GR can be defined as a first state. The state in which the length of the guide rib GRB set in the guide groove GR is less than the length of the guide rib GRB set in the guide groove GR in the first state can be defined as a second state.

[0279] When the second guide part GPb changes from the first state to the second state, a separation distance between the first guide plate GPT1 and the guide frame GFR in the sliding direction may increase.

[0280] Reference FIG. 15A to FIG. 15E , when the electronic device EDa is unfolded ( Fig.15A and Fig. 15B ), the second guide part GPb may be in the first state. Each of the plurality of guide ribs GRB may be disposed in a corresponding guide groove GR among the plurality of guide grooves GR. Here, a maximum length of the guide rib GRB may extend into the guide groove GR.

[0281] When the electronic device EDa is folded ( Fig. 15C , Fig.15D and Fig.15E ), the display module DM and the window module WM can slide into the second receiving groove GR2. The area of ​​the second portion PT2 overlapping with the third bracket BR3 can be increased. Here, the display module DM and the window module WM can be set to overlap the maximum length with the third bracket BR3.

[0282] When the electronic device EDa is folded, the second guide component GPb may be in a second state. Specifically, the second guide plate GPT2 connected to the display module DM may move together with the display module DM. The second guide plate GPT2 may move relative to the first bracket BR1 and along the upper surface BR1-U1 of the first bracket BR1. The guide ribs GRB of the second guide plate GPT2 may move out of the guide groove GR along the sliding direction (e.g., the first direction DR1). The distance between the guide frame GFR and the first guide plate GPT1 may increase. Here, the maximum distance (or maximum displacement) may be defined between the guide frame GFR of the second guide plate GPT2 and the guide frame of the first guide plate GPT1, and the minimum length of the guide ribs GRB may be in the guide groove GR.

[0283] Since the guide plates can slide relative to each other, the direction of movement of the display module DM and the window module WM can be adjusted by the second guide member GPb, which includes a first guide plate GPT1 connected to the first bracket BR1 and a second guide plate GPT2 connected to the display module DM. When the electronic device EDa is folded, the display module DM and the window module WM can be moved along the second receiving groove GR2 (for example, along both the sliding direction and the thickness direction) by the second guide member GPb. Therefore, the window module WM and the display module DM may not be separated from the bracket EDC (refer to Figure 3 ), and can be held in the bracket EDC. Therefore, the folding reliability of the electronic device EDa can be improved.

[0284] Fig.16 is a view for explaining a third guide part GPc for guiding the display module DM according to an embodiment of the present disclosure.

[0285] Fig.16 It is along Figure 1A A cross-sectional view taken along line II-II' shown in FIG.

[0286] Fig.16 1 is a view showing the electronic device EDa in an unfolded state. Here, the display device DD may be located at the first end ( Figure 1A line I-I' in) and the second end ( Figure 1A Line II-II' and Figure 1B Bend at line IV-IV').

Fig.12 The display device DD, the first bracket BR1, the third bracket BR3, and the tip portion TP are the same and thus will be omitted from the description or will be briefly described.

[0288] Reference Fig.16 , when viewed in the second direction DR2, the third guide member GPc may include a roller ROL. The roller ROL may be disposed between the first bracket BR1 and the window WIN. The roller ROL may contact the lower surface of the second portion PT2. The roller ROL may rotate about a rotation axis parallel to the second direction DR2.

[0289] When the electronic device EDa is folded, the second portion PT2 of the window WIN can be moved along the sliding direction (e.g., the first direction DR1) and along the third direction DR3. The second portion PT2 can be moved along the outer surface of the roller ROL. When the electronic device EDa is folded, the roller ROL can be rotated in a clockwise direction around a rotation axis parallel to the second direction DR2 by the second portion PT2.

[0290] The second portion PT2 of the window WIN may be moved along the second receiving groove GR2 (eg, along both the sliding direction and the thickness direction) together with the roller ROL. Therefore, the window module WM and the display module DM may not be separated from the bracket EDC (refer to Figure 3 ). In an embodiment, the roller ROL may be actively driven to rotate, and the friction between the rotating roller ROL and the display module DM may cause the display device DD to slide passively along the sliding direction. In an embodiment, the active sliding of the display module DM may cause the roller ROL to rotate passively and allow the display device DD to slide in the sliding direction. Therefore, the folding reliability of the electronic device EDa may be improved.

[0306] The second adhesive part GRP2 may be disposed between the window WIN and the first side wall WB1. The second adhesive part GRP2 may be disposed directly on the lower surface of the window WIN and the upper surface of the first side wall WB1. Therefore, the window WIN and the fourth bracket BR4 (specifically, the first side wall WB1) may be bonded to each other by the second adhesive part GRP2.

The bent track portion CBTa may be defined as a portion of the track CTa that is bent and connects the first track portion CT1a and the second track portion CT2a to each other.

[0339] When viewed in the second direction DR2, the first rail portion CT1a may be longer than the second rail portion CT2a.

[0340] Each of the first rail portion CT1a, the second rail portion CT2a, and the bent rail portion CBTa may include a rail protrusion PRPa.

[0341] The rail protrusion PRPa may be provided on surfaces of the first rail portion CT1a and the second rail portion CT2a facing each other. The rail protrusion PRPa may be provided on a surface of the bent rail portion CBTa facing the wheel WHa.

[0342] The wheel WHa may be provided between the first rail portion CT1a and the second rail portion CT2a. The wheel WHa may be connected to a portion of the first rail portion CT1a, a portion of the second rail portion CT2a, and the bent rail portion CBTa.

[0343] The wheel protrusions PRGa may be provided on the outer surface of the wheel WHa. The wheel protrusions PRGa may be spaced apart from each other at predetermined intervals along the outer surface of the wheel WHa.

[0344] The rail protrusions PRPa of the first rail portion CT1a, the second rail portion CT2a, and the bent rail portion CBTa may engage with the wheel protrusions PRGa. Therefore, when the rail protrusions PRP move along the outer surface of the wheel WHa, the wheel WHa may rotate about a rotation axis parallel to the second direction DR2.

[0345] The electronic device EDc may further include a tip portion TPa. The tip portion TPa may be disposed on an inner surface of the third bracket BR3a. The tip portion TPa may be disposed adjacent to an upper portion of the third bracket BR3a.

[0346] The tip portion TPa may prevent foreign matter from penetrating into the second receiving groove GR2a. The tip portion TPa may block foreign matter from penetrating into the second receiving groove GR2a.

[0347] refer to Fig.18B , Fig.19B , Fig.19C and Fig.19D When the electronic device EDc is folded outward, the third bracket BR3a may be disposed under the second bracket BR2a.

[0348] When the electronic device EDc is folded outward, the display unit DSP and the window module WM can be moved from the receiving slot 2-1GR2-1a ( Fig.19B ) moves to the first position inside the receiving groove 2-1GR2-1a ( Fig.19D ) outside. As the display unit DSP and the window module WM move out of the receiving groove 2-1GR2-1a, the area of ​​the second portion PT2a overlapping with the third bracket BR3a can be reduced. That is, the exposed area of ​​the second portion PT2a (corresponding to the bracket EDC at the first corner EG1 and the second corner EG2 (refer to Figure 3 )'s inner surface area can be increased.

[0349] When the display unit DSP and the window module WM move from the receiving groove 2-1GR2-1a to the outside thereof, the length of the second rail portion CT2a extending along the display unit DSP may increase, and the length of the first rail portion CT1a may decrease. Specifically, the unattached portion of the first rail portion CT1a originally disposed along the first bracket BR1a may move by moving along the outer surface of the wheel WHa to extend along the display unit DSP.

[0350] Although not shown, when the electronic device EDc changes from the outer folded state to the unfolded state, a portion of the second rail portion CT2a may be moved onto the first bracket BR1a along the outer surface of the wheel WHa. At this time, the length of the first rail portion CT1a may increase, and the length of the second rail portion CT2a may decrease.

[0351] Even if the electronic device EDc repeatedly performs the outer folding and unfolding operation, the fourth guide member GPd can move the display unit DSP and the window module WM into the receiving groove 2-1GR2-1a without moving out of the first bracket BR1a and the third bracket BR3a and being visible from the outside of the first bracket BR1a and the third bracket BR3a. Therefore, the window module WM and the display module DM can be moved out of the bracket EDC (refer to FIG. Figure 3 ). Therefore, the folding reliability of the electronic device EDc can be improved.

[0357] Reference Fig. 20A and Fig. 20B The electronic device EDd may have a rectangular shape having long sides extending in the first direction DR1 and short sides extending in the second direction DR2. However, not limited thereto, the electronic device EDd may have various shapes such as a circular shape and other polygonal shapes.

[0358] An upper surface of the electronic device EDd may be defined as a display surface DSd, and the display surface DSd may have a plane defined by the first direction DR1 and the second direction DR2. An image IM generated by the electronic device EDd may be provided to a user through the display surface DSd.

[0359] The display surface DSd may include a display area DAd and a non-display area NDAd around the display area DAd. The display area DAd may be defined as a front surface of the electronic device EDd. The display area DAd may display an image IM, and the non-display area NDAd may not display the image IM.

[0360] Reference Fig. 20A and Fig. 20B , the electronic device EDd may be rolled into a roll shape (e.g., has a roll shape). The electronic device EDd may be rolled around a roll axis RXa parallel to the second direction DR2. The electronic device EDd may be rolled around the roll axis RXa in the first direction DR1 as the roll direction. The electronic device EDd may be rolled outward so that the display surface DSd faces outward.

[0361] When the electronic device EDd is curled outwardly, one side of the electronic device EDd in the first direction DR1 (for example, the first edge portion) may be spaced apart from the curling axis RXa, and the opposite side of the electronic device EDd in the first direction DR1 may be adjacent to the curling axis RXa (for example, closer to the curling axis RXa than the side that is the first edge portion). The curling of the electronic device EDd relative to the curling axis RXa may start at the second edge portion. Hereinafter, one side of the electronic device EDd in the first direction DR1 may be defined as a first region, and the opposite side of the electronic device EDd in the first direction DR1 may be defined as a second region. When the electronic device EDd is curled, the second region may be positioned in the center of the curled electronic device EDd. The electronic device EDd may curl around the curling axis RXa starting from the second region.

[0362] For example, when the initial portion of the electronic device EDd starts to curl from the second edge portion, the second region of the electronic device EDd may be in a bent or curved state, and the remaining portion of the electronic device EDd up to the first region of the electronic device EDd may be in a flat state. However, the present disclosure is not limited thereto, and when the electronic device EDd is fully curled, the first region of the electronic device EDd may also be in a bent or curled state.

Fig. 21B is along Fig. 20A A cross-sectional view taken along the line XI-XI′ shown in FIG. 1 (eg, the second non-curled edge portion). Fig. 21C It is along Fig. 20B A cross-sectional view taken along line XII-XII' shown in FIG. 1 (eg, a curled edge portion).

[0364] Fig.21A and Fig. 21B is a cross-sectional view of a non-curled edge portion of the electronic device EDd in an uncurled state, and Fig. 21C is a cross-sectional view of the electronic device EDd in a rolled state.

[0365] Fig. 21C Only the portion adjacent to the periphery of the second region is shown. Fig. 21C The orientation of the structure in is basically similar to Fig. 21B of the orientation, but it will be understood that Fig. 21C The structure in can be rotated about the rotation axis RXa to different orientations.

[0366] In addition to the first area NFA1a (ref. Fig.11 ), Fig.21A The components shown in Fig.11The components shown in Fig.19A The components shown in FIG. 1 are substantially the same. Therefore, for ease of description, the Fig.21A Description.

Fig.19B and Fig.19C The display device DD, the first bracket BR1a, the third bracket BR3a, the first adhesive part GRP1a, the protrusion BPPa and the tip portion TPa shown in FIG. 1 are substantially the same and will therefore be omitted from the description or will be briefly described. The upper surface BR1-Ub of the first bracket BR1b may include an upper surface 1-1BR1-U1b as a first upper surface portion and an upper surface 1-2BR1-U2b as a second upper surface portion.

[0368] Reference Fig. 21B , the fifth guide part GPe may be disposed between the display unit DSP and the first bracket BR1b. A portion of the fifth guide part GPe may be connected to the upper surface BR1-U1b of the first bracket BR1b. Another portion of the fifth guide part GPe may be connected to the lower surface of the panel protection layer PPL.

[0369] The fifth guide member GPe may include a track CTb and a wheel WHb disposed inside the track CTb bent in a curved shape. A portion of the track CTb may be disposed on the upper surface BR1-U1b of the first bracket BR1b, and another portion of the track CTb may be disposed on the lower surface of the panel protection layer PPL.

[0370] The track CTb may include a first track portion CT1b, a bent track portion CBTb, and a second track portion CT2b. The first track portion CT1b may be defined as a portion of the track CTb disposed on the upper surface BR1-U1b of the first bracket BR1b. The second track portion CT2b may be defined as a portion of the track CTb disposed on the lower surface of the panel protection layer PPL to face the first track portion CT1b. The bent track portion CBTb may be defined as a portion of the track CTb that is bent and connects the first track portion CT1b and the second track portion CT2b to each other.

[0371] When the electronic device EDd is in an uncurled state, the first rail portion CT1b may be longer than the second rail portion CT2b.

[0372] Reference FIG. 21A to FIG. 21C, when the electronic device EDd is rolled, the first molding part MP1 may fix one side of the display unit DSP and one side of the support plate PLT at, for example, the same side adjacent to the first non-rolled edge portion. Therefore, when the electronic device EDd is rolled, one side of the display unit DSP and one side of the support plate PLT may not slide and may be fixedly disposed. One side of the display unit DSP and one side of the support plate PLT may be defined as a side adjacent to the second bracket BR2b. A portion of the window WIN overlapping the second bracket BR2b may be defined as a first portion PT1b.

[0373] When the electronic device EDd is curled, the opposite side of the display unit DSP and the opposite side of the window module WM can slide or slide at a position adjacent to the second edge portion, for example, to define the curled edge portion. The opposite side of the display unit DSP and the opposite side of the window module WM can be moved by the sliding. The opposite side of the display unit DSP and the opposite side of the window module WM can be moved from the inside of the first sub-groove GR2-1b of the second receiving groove GR2b to the outside of the first sub-groove GR2-1b. That is, one end of the window module WM can move from the first sub-groove GR2-1b to the second sub-groove GR2-2b. When the electronic device EDd is curled outward, the area of ​​the second part PT2b can be reduced. The opposite side of the display unit DSP and the opposite side of the window module WM can be defined as the side facing the third bracket BR3b.

[0374] As the display unit DSP and the window module WM move, the track CTb connected to the display unit DSP may move along the outer surface of the wheel WHb. Specifically, a portion of the first track portion CT1b may move along the outer surface of the wheel WHb to the lower surface of the panel protection layer PPL. Therefore, when the electronic device EDd is curled, the length of the first track portion CT1b may decrease. When the electronic device EDd is curled, the length of the second track portion CT2b may increase.

[0375] Even if the electronic device EDd repeatedly performs rolling and unrolling operations, the fifth guide member GPe may enable the display unit DSP and the window module WM to move along the second receiving groove GR2b (e.g., in both the sliding direction and the thickness direction) without moving out of the first bracket BR1b and the third bracket BR3b. Therefore, the window module WM and the display module DM may not be separated from the bracket EDC (refer to Figure 3 ). Therefore, the curling reliability of the electronic device EDd can be improved.

[0376] although Fig. 21C The electronic device EDd is shown to include a fifth guide member GPe, but the present disclosure is not limited thereto. For example, although not shown, Fig. 21C The electronic device EDd shown in FIG. 1 may include FIG. 15A to FIG. 15EIn this case, when the electronic device EDd is in the outer rolled state, the second guide member GPb may be in the first state. When the electronic device EDd is in the non-rolled state, the second guide member GPb may be in the second state.

[0377] Although not shown, Fig. 21C The electronic device EDd shown in FIG. 1 may include Fig.16 In this case, when the electronic device EDd is changed from the non-rolled state to the rolled state, the third guide member GPc may rotate in the counterclockwise direction around a rotation axis parallel to the second direction DR2.

[0378] Fig.22A and Fig. 22B is a view for explaining the electronic device EDe according to the embodiment of the present disclosure.

[0379] Fig.22A is a perspective view of the inwardly curled electronic device EDe, and Fig. 22B It is along Fig.22A A cross-sectional view at the curled edge portion taken along the line XIII-XIII' shown in FIG.

[0380] For ease of description, Fig. 22B Only Fig.22A Part of the electronic device EDe.

[0381] In addition to the curling direction, Fig.22A The electronic device EDe shown in Fig. 20A The electronic devices EDd shown in FIG. 1 are substantially the same, and thus the following description will focus on the differences. The display surface DSe may include a display area DAe and a non-display area NDAe around the display area DAe.

Fig. 21B The display device DD, the first bracket BR1b, the third bracket BR3b, the fifth guide part GPe, and the tip portion TPb shown in FIG. 1 are substantially the same, and thus will be omitted from the description or will be briefly described.

[0383] Reference Fig.22A , the electronic device EDe may be rolled into a roll shape. The electronic device EDe may be rolled around a roll axis RXb parallel to the second direction DR2. The electronic device EDe may be rolled around the roll axis RXb in the first direction DR1. The electronic device EDe may be rolled inwardly so that the display surface DSe does not face outward.

[0384] When the electronic device EDe is curled inwardly, one side of the first edge portion of the electronic device EDe in the first direction DR1 may be spaced apart from the curling axis RXb, and the opposite side of the second edge portion of the electronic device EDe in the first direction DR1 may be adjacent to the curling axis RXb. Hereinafter, one side of the electronic device EDe in the first direction DR1 may be defined as a first region, and the opposite side of the electronic device EDe in the first direction DR1 may be defined as a second region. When the electronic device EDe is curled, the second region may be defined in the center of the curled electronic device EDe. The electronic device EDe may start curling from the second region.

[0385] For example, when the electronic device EDe is curled inwardly, the second region of the electronic device EDe may be in a bent state. The first region of the electronic device EDe and the remaining portion between the bent state and the first edge portion may be in a flat state. However, the present disclosure is not limited thereto, and when the electronic device EDe is fully curled, the first region of the electronic device EDe may also be in a bent state.

[0386] Reference Fig.22A and Fig. 22B , when the electronic device EDe is curled inwardly, the opposite side of the display unit DSP and the opposite side of the window module WM can slide. The opposite side of the display unit DSP and the opposite side of the window module WM can move by the sliding. The opposite side of the display unit DSP and the opposite side of the window module WM can move along the second receiving groove GR2c (for example, along both the sliding direction and the thickness direction) (such as moving from the second sub-groove GR2-2c to the first sub-groove GR2-1c). The area of ​​the second portion PT2c overlapping with the third bracket BR3c can be increased. The opposite side of the display unit DSP and the opposite side of the window module WM can be defined as the side facing the third bracket BR3c.

[0387] As the display unit DSP and the window module WM move, the track CTc connected to the display unit DSP can move along the outer surface of the wheel WHc. The track CTc may include a first track portion CT1c, a bent track portion CBTc, and a second track portion CT2c. Specifically, a portion of the second track portion CT2c may move along the outer surface of the wheel WHc onto the upper surface BR1-U1c of the first bracket BR1c. The upper surface BR1-Uc of the first bracket BR1c may include an upper surface 1-1BR1-U1c as a first upper surface portion and an upper surface 1-2BR1-U2c as a second upper surface portion. Therefore, when the electronic device EDe is curled, the length of the second track portion CT2c may be reduced. When the electronic device EDe is curled, the length of the first track portion CT1c may be increased.

[0388] Even if the electronic device EDe repeatedly performs rolling and unrolling operations, the sixth guide member GPf can enable the display unit DSP and the window module WM to move along the second receiving groove GR2c (e.g., in both the sliding direction and the thickness direction) without moving out of the first bracket BR1c and the third bracket BR3c. Therefore, the window module WM and the display module DM may not be separated from the bracket EDC (refer to Figure 3 ). Therefore, the curling reliability of the electronic device EDe can be improved.

[0389] Reference FIG. 15A to FIG. 15E , Fig.22A and Fig. 22B , Fig.22A and Fig. 22B The electronic device EDe is shown to include a sixth guide component GPf. However, the present disclosure is not limited thereto. For example, although not shown, Fig.22A and Fig. 22B The electronic device EDe shown in FIG. 1 may include FIG. 15A to FIG. 15E In this case, when the electronic device EDe is in the inner curled state, the second guide member GPb may be in the second state. When the electronic device EDe is in the non-curled state, the second guide member GPb may be in the first state.
