[0051] Some aspects of embodiments of this disclosure and methods of implementing them can be more readily understood by referring to the detailed description of the embodiments and the accompanying drawings. Hereinafter, embodiments will be described in more detail with reference to the accompanying drawings. However, the described embodiments can be implemented in various different forms and should not be construed as being limited to the embodiments shown herein. Rather, these embodiments are provided as examples so that this disclosure will be thorough and complete, and will fully convey aspects of this disclosure to those skilled in the art. Therefore, processes, components, and techniques unnecessary for those skilled in the art to fully understand aspects of this disclosure are not described.

[0052] Unless otherwise stated, throughout the drawings and written description, the same reference numerals, characters, or combinations thereof refer to the same elements, and therefore their descriptions will not be repeated. Additionally, portions unrelated to the description of the embodiments may be omitted to make the description clear. In the drawings, the relative dimensions of elements, layers, and regions may be exaggerated for clarity. Furthermore, crosshairs and / or shading are generally provided in the drawings to clarify the boundaries between adjacent elements. Therefore, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for particular materials, material properties, dimensions, proportions, commonalities between illustrated elements, and / or any other characteristics, properties, or characteristics of the elements, unless otherwise stated.

[0053] Various embodiments are described herein with reference to cross-sectional views that serve as schematic diagrams of implementations and / or intermediate structures. Therefore, variations in the shape of the figures will be anticipated, for example, due to manufacturing techniques and / or tolerances. Furthermore, the specific structural or functional descriptions disclosed herein are merely illustrative for the purpose of describing embodiments according to the concepts of this disclosure. Therefore, the embodiments disclosed herein should not be construed as limited to the shape of the specifically shown areas, but should include, for example, deviations in shape due to manufacturing processes.

[0054] For example, an implantation area shown as rectangular will typically have rounded or curved features at its edges and / or a gradient of implantation concentration, rather than a binary change from the implantation area to the non-implantation area. Similarly, the implantation area formed by implantation may result in some implantation in the area between the implantation area and the surface through which the implantation occurs. Therefore, the areas shown in the figures are schematic in nature, and their shapes are not intended to represent the actual shape of the areas of the device, nor are they intended to be limiting. Furthermore, as those skilled in the art will recognize, the described embodiments can be modified in various different ways without departing from the spirit and scope of this disclosure.

[0055] In the detailed description, numerous specific details are set forth for illustrative purposes to provide a thorough understanding of the various embodiments. However, it will be apparent that various embodiments may be practiced without these specific details or with one or more equivalent arrangements. In other instances, well-known structures and apparatuses are shown in block diagram form to avoid unnecessarily obscuring the various embodiments.

[0056] It will be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, areas, layers, and / or portions, these elements, components, areas, layers, and / or portions should not be limited by these terms. These terms are used to distinguish one element, component, area, layer, or portion from another element, component, area, layer, or portion. Therefore, without departing from the spirit and scope of this disclosure, the first element, first component, first area, first layer, or first portion described below may be referred to as a second element, second component, second area, second layer, or second portion.

[0057] For ease of explanation, spatial relative terms such as “below,” “under,” “down,” “below,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature and another element (or feature) or feature (or feature) as shown in the figures. It will be understood that, in addition to the orientation depicted in the figures, spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “below,” “under,” or “below” other elements or features will consequently be oriented “above” other elements or features. Thus, the exemplary terms “below” and “below” may encompass both above and below orientations. The device may be otherwise oriented (e.g., rotated 90 degrees or in other orientations), and the spatial relative descriptive terms used herein should be interpreted accordingly. Similarly, when a first part is described as being arranged “above” a second part, this means that the first part is arranged above or below the second part, not limited to its upper side based on the direction of gravity.

[0058] Furthermore, in this specification, the phrase "in a plane" or "plan view" means the target portion viewed from above, and the phrase "in a cross section" means the cross section formed by vertically cutting the target portion viewed from the side.

[0059] It will be understood that when a component, layer, area, or assembly is referred to as "formed on," "on," "connected to," or "coupled to" another component, layer, area, or assembly, it can be directly formed on, directly connected to, or directly coupled to, the other component, layer, area, or assembly, or indirectly formed on, indirectly connected to, or indirectly coupled to, the other component, layer, area, or assembly, such that one or more intermediate components, layers, areas, or assemblies may exist. For example, when a layer, area, or assembly is referred to as "electrically connected" or "electrically coupled to" another layer, area, or assembly, it can be directly electrically connected or electrically coupled to the other layer, area, and / or assembly, or there may be intermediate layers, areas, or assemblies. However, "directly connected / directly coupled" means that one component is directly connected to or coupled to another component without any intermediate components. Similarly, other expressions describing relationships between components can be interpreted in a similar way, such as "between," "directly between," or "adjacent to" and "directly adjacent to." Furthermore, it will be understood that when an element or layer is referred to as "between" two elements or layers, it can be the only element or layer between the two elements or layers, or there may be one or more intermediate elements or layers.

[0060] For the purposes of this disclosure, when a statement such as “at least one of…” follows an element of a list, it modifies the entire list rather than individual elements within the list. For example, “at least one of X, Y, and Z” and “at least one selected from the group consisting of X, Y, and Z” can be interpreted as any combination of two or more of X, Y, Z, such as, for example, XYZ, XYY, YZ, and ZZ, or any variations thereof. Similarly, a statement such as “at least one of A and B” can include A, B, or A and B. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. For example, a statement such as “A and / or B” can include A, B, or A and B.

[0061] In this example, the x-axis, y-axis, and / or z-axis are not limited to the three axes of a Cartesian coordinate system and can be interpreted in a broader sense. For example, the x-axis, y-axis, and z-axis can be perpendicular to each other, or they can represent different directions that are not perpendicular to each other. The same applies to the first direction, the second direction, and / or the third direction.

[0062] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure. As used herein, the singular forms “a” and “an” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that, when used in this specification, the terms “comprise,” “comprising,” “have,” “having,” “include,” and “including” specify the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof.

[0063] As used herein, the terms “substantially,” “about,” “approximately,” and similar terms are used as approximate terms rather than terms of degree and are intended to explain the inherent biases in measured or calculated values ​​that would be recognized by one of ordinary skill in the art. As used herein, “about” or “approximately” includes the value as well as the average of the acceptable range of deviations of a particular value as determined by one of ordinary skill in the art, taking into account the measurement in question and the errors associated with the measurement of the particular quantity (i.e., limitations of the measurement system). For example, “about” may mean within one or more standard deviations, or within ±30%, ±20%, ±10%, ±5% of the value. Additionally, the word “may” as used in describing embodiments of this disclosure means “one or more embodiments of this disclosure.”

[0064] When one or more implementations can be implemented differently, a particular process sequence can be performed differently than the described sequence. For example, two consecutively described processes can be performed substantially simultaneously, or in the reverse order of their description.

[0065] Furthermore, any numerical range disclosed and / or described herein is intended to include all subranges containing the same numerical precision within the described range. For example, the range “1.0 to 10.0” is intended to include all subranges between the described minimum value 1.0 and the described maximum value 10.0 (and including both the described minimum value 1.0 and the described maximum value 10.0), i.e., having a minimum value equal to or greater than 1.0 and a maximum value equal to or less than 10.0, such as, for example, 2.4 to 7.6. Any maximum numerical limit described herein is intended to include all lower numerical limits contained therein, and any minimum numerical limit described herein is intended to include all higher numerical limits contained therein. Therefore, the applicant reserves the right to modify this specification, including the claims, to clearly describe any subranges contained within the range expressly described herein.

[0066] Unless otherwise specified, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It will also be understood that terms (such as those defined in common dictionaries) shall be interpreted as having the same meaning as they have in the context of the relevant technology and / or this disclosure, and shall not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0067] Figure 1 A perspective view is shown illustrating a display device manufactured using a support member protected by a release film, according to some embodiments of the present disclosure. Figure 2 The demonstration is shown Figure 1 The image depicts a folded view of the display device.

[0068] Reference Figure 1 According to some embodiments of the present disclosure, the display device DD may have a rectangular shape having a long side extending in a first direction DR1 and a short side extending in a second direction DR2 intersecting / crossing the first direction DR1. However, the present disclosure is not limited thereto, and the display device DD may have various shapes such as a circular shape or a polygonal shape. The display device DD may be a flexible display device.

[0069] The third direction DR3 is defined herein as the direction that intersects substantially vertically with the plane formed by the first direction DR1 and the second direction DR2. In this specification, the phrase "when viewed in a plane" may be defined as "when viewed on the third direction DR3".

[0070] The display device DD may include a folded region FA and multiple non-folded regions NFA1 and NFA2. The non-folded regions NFA1 and NFA2 may include a first non-folded region NFA1 and a second non-folded region NFA2. The folded region FA may be located between the first non-folded region NFA1 and the second non-folded region NFA2. The folded region FA, the first non-folded region NFA1, and the second non-folded region NFA2 may be arranged in a second direction DR2.

[0071] Although a folded region FA and two non-folded regions NFA1 and NFA2 are shown by way of example, no limitation is imposed on the number of folded regions FA and the number of non-folded regions NFA1 and NFA2. For example, the display device DD may include more than two non-folded regions and multiple folded regions between the non-folded regions.

[0072] The display device DD may have a top surface defined as a display surface DS, and the display surface DS may have a plane defined by a first direction DR1 and a second direction DR2. The display surface DS may provide the user with an image IM generated from the display device DD.

[0073] The display surface DS may include a display area DA and a non-display area NDA surrounding the display area DA. The display area DA may display an image IM, and the non-display area NDA may not display an image IM. The non-display area NDA may surround the display area DA and may provide a colored edge to the display device DD.

[0074] The display device DD may include a plurality of sensors SN and at least one camera CAM. The sensor SN and camera CAM may be adjacent to the edge of the display device DD. The sensor SN and camera CAM may be located in the display area DA adjacent to the non-display area NDA. The sensor SN and camera CAM may be located in a first non-folding area NFA1 and / or a second non-folding area NFA2.

[0075] The sensor SN can be, for example, a proximity sensor, but the type of sensor SN is not limited. The camera CAM can capture external images.

[0076] Reference Figure 2 The display device DD can be a foldable display device that can be folded or unfolded. For example, the folding region FA can be bent about a folding axis FX parallel to the first direction DR1, and thus the display device DD can be folded. The folding axis FX can be defined as a long axis parallel to the long side of the display device DD.

[0077] When the display device DD is folded, the first non-folded area NFA1 and the second non-folded area NFA2 can face each other, and the display device DD can be folded inward so that the display surface DS is not exposed externally.

[0078] Figure 3 An exploded perspective view is shown illustrating a release film and a support member protected by the release film according to some embodiments of the present disclosure.

[0079] Reference Figure 3 Release film RFL can be applied to the upper and lower portions of the support member SUP, thereby protecting the support member SUP. The support member SUP can be protected by the release film RFL and can be transferred to the process chamber used to manufacture the display device DD.

[0080] The release film RFL may include a first release film RFL1, a second release film RFL2, and a third release film RFL3. The first release film RFL1 may be on or above the support SUP. The second release film RFL2 and the third release film RFL3 may be below the support SUP. The third release film RFL3 may be adjacent to the second release film RFL2.

[0081] The first release film RFL1 protects the upper portion of the support SUP, and the second release film RFL2 and the third release film RFL3 protect the lower portion of the support SUP. In some embodiments, each of the first release film RFL1, the second release film RFL2, and the third release film RFL3 may include a base film and an adhesive on one side of the base film.

[0082] The second release film RFL2 may include a first sub-release film RFL2_1 below the support SUP and a second sub-release film RFL2_2 below the first sub-release film RFL2_1.

[0083] Each of the first release film RFL1, the second release film RFL2, and the third release film RFL3 may have a planar structure, which will be referred to below. Figure 6 and Figure 7 Let's discuss this in detail.

[0084] The support component SUP may include a first plate PLT1, a cover layer COV, a second plate PLT2, a buffer layer CUL, an insulating layer INL, and a boundary adhesive layer BAD.

[0085] The first plate PLT1 may be located below the first release film RFL1. The first plate PLT1 may have an opening OP that overlaps with the folded region FA. The opening OP may have a feature that will be located below... Figure 4 and Figure 5 The structure shown in the figure.

[0086] The first plate PLT1 may comprise a material having an elastic modulus equal to or greater than about 60 GPa. The first plate PLT1 may comprise a metallic material such as stainless steel. For example, the first plate PLT1 may comprise SUS304, but this disclosure is not limited thereto, and the first plate PLT1 may comprise a variety of metallic materials.

[0087] The cover layer COV may be located below the first plate PLT1. The cover layer COV may have a lower elastic modulus than the first plate PLT1. For example, the cover layer COV may comprise thermoplastic polyurethane or rubber, but this disclosure is not limited thereto. The cover layer COV may be manufactured in sheet form and attached to the first plate PLT1.

[0088] The second plate PLT2 may be located beneath the COV capping layer. The second plate PLT2 may include metal. The second plate PLT2 may serve as a heat-radiating layer. The second plate PLT2 may include copper, copper alloys, and / or graphite. However, this is merely an example, and the second plate PLT2 may include various metals (e.g., Alloy (INVAR is a registered trademark of Aperam Alloys IMPHY Joint Stock Company) or stainless steel.

[0089] The cushioning layer CUL may be located below the second plate PLT2. The cushioning layer CUL absorbs external impacts. The cushioning layer CUL may include an elastic foam sheet. The cushioning layer CUL may include foam, sponge, polyurethane, or thermoplastic polyurethane.

[0090] The insulating layer INL may be located beneath the buffer layer CUL. The insulating layer INL may include a dielectric strip. The insulating layer INL reduces or prevents the introduction of static electricity.

[0091] The boundary adhesive layer BAD may be along the edge of the first plate PLT1. The boundary adhesive layer BAD may extend on the opposite sides of the first plate PLT1 that face each other relative to the first direction DR1.

[0092] The boundary adhesive layer BAD may be omitted from one of the opposing sides of the first plate PLT1 in the second direction DR2, while extending upward (e.g., downward) from the other of the opposing sides of the first plate PLT1 in the second direction DR2.

[0093] When viewed in a plane / planar view, the second plate PLT2, the buffer layer CUL, the insulating layer INL, and the boundary adhesive layer BAD can be separated at the areas overlapping with the folded area FA.

[0094] The cover layer COV, the second plate PLT2, the buffer layer CUL, and the insulating layer INL may have corresponding sides OS1, OS2, OS3, and OS4 adjacent to one side of the first plate PLT1, and the sides OS1, OS2, OS3, and OS4 may be patterned into appropriate shapes.

[0095] The first release film RFL2_1 and the second release film RFL2_2 may have their respective sides OS5 and OS6, each of which has a shape corresponding to the shape of the side OS1 of the cover layer COV, the side OS2 of the second plate PLT2, the side OS3 of the buffer layer CUL and the side OS4 of the insulating layer INL.

[0096] The third release film RFL3 may have a side portion OS7 facing the side portion OS5 of the first sub-release film RFL2_1 and the side portion OS6 of the second sub-release film RFL2_2, and the side portion OS7 of the third release film RFL3 may have a shape opposite to that of the side portion OS5 of the first sub-release film RFL2_1 and the side portion OS6 of the second sub-release film RFL2_2. For example, when the first sub-release film RFL2_1 and the second sub-release film RFL2_2 are defined to have their engraved side portions OS5 and OS6, the third release film RFL3 may be defined to have a side portion OS7 with embossing corresponding to the engraved side portions OS5 and OS6.

[0097] Figure 3 The example illustrates components with similar thicknesses, but in other implementations, components may have different thicknesses. This will be discussed below. Figure 8 The diagram shows the structure associated with this thickness.

[0098] Figure 4 The demonstration is shown Figure 3 The enlarged three-dimensional view of the first plate depicted in the text, and Figure 5 The demonstration is shown Figure 4 An enlarged plan view of part AA depicted in the figure.

[0099] Reference Figure 4 and Figure 5 The first plate PLT1 may include a first plate PLT1_1, a first plate PLT1_2, and a folding plate PLT_F. The folding plate PLT_F may be located between the first plate PLT1_1 and the first plate PLT1_2.

[0100] The folded plate PLT_F may have multiple openings OP defined therein. The openings OP may be arranged appropriately. The openings OP may be arranged in a grid shape.

[0101] Because the folding plate PLT_F has an opening OP defined therein, the folding plate PLT_F can have a reduced area to decrease its rigidity. Therefore, the flexibility of the folding plate PLT_F can be increased compared to the case where the folding plate PLT_F has no opening OP. Therefore, the folding plate PLT_F can be appropriately foldable.

[0102] The first plate PLT1 may have a first hole H1 and a plurality of second holes H2 defined therein. The first hole H1 and the second holes H2 may be adjacent to the edge of the first plate PLT1. For example, one of the second holes H2 and the first hole H1 may be defined by the first-second plate PLT1_2, and the other of the second holes H2 may be defined by the first-first plate PLT1_1, but no restriction is imposed on the position of either the first hole H1 or the second hole H2.

[0103] The camera (CAM) can be in the first hole H1. The sensor (SN) can be in the second hole H2.

[0104] Figure 6 The demonstration is shown Figure 3 The diagram depicts the support member and the first release film on the support member.

[0105] Figure 6 The opening defined by the first plate PLT1 is shown as gray, as an example. Furthermore, the first plate PLT1 is shown to have a shape aligned with the shape of the first release film RFL1, and the first plate PLT1 is located below the first release film RFL1. References will also be made below as needed. Figure 3 .

[0106] Reference Figure 3 and Figure 6 The first release film RFL1 may cover the upper portion of the support member SUP. The first release film RFL1 may cover the first plate PLT1. When viewed in a plan view, the first release film RFL1 may include a plurality of first shanks HD1 protruding outward beyond the support member SUP.

[0107] If appropriate, the first shank HD1 can be used to remove the first release film RFL1. For example, a delamination tool can clamp the first shank HD1 to separate the first release film RFL1.

[0108] Figure 7 The demonstration is shown Figure 3 The diagram depicts the support member and the second release film below the support member.

[0109] As an example, the insulating layer INL and the boundary adhesive layer BAD are shown to have shapes aligned with the shapes of the second release film RFL2 and the third release film RFL3, with the insulating layer INL and the boundary adhesive layer BAD located below the second release film RFL2 and the third release film RFL3. References will also be made below as needed. Figure 3 .

[0144] Reference Figure 11A A cutting tool KNF (or a cutting device) can be prepared, and the cutting tool KNF can move along the first direction DR1 to cut the first part PT1 of the second release film RFL2. Therefore, a first sub-cutting area S_INC1 can be formed in the first part PT1. For example, the first sub-cutting area S_INC1 can be about 3 mm long.

[0145] Reference Figure 11B The cutting tool KNF can move along the second direction DR2 to cut the first portion PT1 of the second release film RFL2. Therefore, a second sub-cutting area S_INC2 can be formed in the first portion PT1. The cutting tool KNF can move across the first sub-cutting area S_INC1, and thus the second sub-cutting area S_INC2 can be formed in the first portion PT1. For example, the second sub-cutting area S_INC2 can be approximately 3 mm long.

The fourth sub-cutting region S_INC4 may intersect with the third sub-cutting region S_INC3. The third sub-cutting region S_INC3 and the fourth sub-cutting region S_INC4 may intersect each other and may be defined as a single unit to form the second cutting region INC2 having a cross shape.

[0154] Figure 14 and Figure 15 The illustration shows the display module being attached to... Figure 8 The cross-sectional view depicting the process of the support component.

[0155] Reference Figure 14 The first release film RFL1 can be removed from the support SUP.

[0156] Reference Figure 15 The display module DM can be attached to the support SUP. The display module DM can be attached to the top surface of the first plate PLT1. The first plate PLT1 supports the display module DM. The first plate PLT1 and the second plate PLT2 allow the display module DM to have enhanced thermal radiation performance.

[0157] The second plate PLT2_1 can support the first non-folded region NFA1. The second plate PLT2_2 can support the second non-folded region NFA2. The second plate PLT2_1 and the second plate PLT2_2 can extend toward the folded region FA, and therefore can be adjacent to each other at or near the folded region FA.

[0158] In the folded region FA, the second plate PLT2_1 and the second plate PLT2_2 can support the folded plate PLT_F, which defines the opening OP. When downward pressure is applied to the folded plate PLT_F, the second plate PLT2_1 and the second plate PLT2_2 can prevent or partially prevent partial deformation of the folded plate PLT_F.

[0159] The display module DM may include a display panel DP, an anti-reflective layer RPL, a window WIN, a window protective layer WP, a panel protective layer PPL, a barrier layer BRL, and fifth adhesive layers AL5 to tenth adhesive layers AL10.

[0160] A display panel DP may include multiple pixels for displaying images. The display panel DP may be a flexible display panel. For example, a display panel DP may include multiple electronic components on a flexible substrate.

[0161] According to some embodiments of this disclosure, an emitting display panel can be used as the display panel DP. For example, the display panel DP can be an organic light-emitting display panel or a quantum dot light-emitting display panel. The emitting layer of an organic light-emitting display panel may include an organic light-emitting material. The emitting layer of a quantum dot light-emitting display panel may include quantum dots or quantum rods. Examples of using an organic light-emitting display panel as the display panel DP will be described below.

[0162] The display panel DP may include a first region AA1, a second region AA2, and a curved region BA between the first region AA1 and the second region AA2. The data driver DDV may be located in the second region AA2.

[0163] An anti-reflective layer (RPL) may be present on a display panel (DP). The RPL can be defined as a film used to reduce or prevent the reflection of external light. The RPL reduces the reflectivity of light incident on the display panel (DP).

[0164] When external light traveling toward and reflecting from the display panel DP is again presented to the user, a mirror-like effect occurs, and the external light is visible to the user. To reduce or prevent the effects of this phenomenon, the anti-reflective layer RPL may include multiple color filters that display the same colors generated from the pixels.

[0165] The color filter can be configured such that external light is filtered to the same colors as those generated from the pixels. In this case, the external light is invisible to the user. However, this disclosure is not limited thereto, and the antireflective layer RPL may include one or more of a retarder and a polarizer.

[0166] The window (WIN) can be placed on the anti-reflective layer RPL. The window protects the display panel (DP) and the anti-reflective layer RPL from external scratches. The window can also be optically transparent.

[0167] Window WIN may include glass. Window WIN may be limited to ultra-thin glass (UTG). However, this disclosure is not limited thereto, and window WIN may include a synthetic resin film.

[0168] The window WIN can have a single-layer or multi-layer structure. For example, the window WIN can include multiple synthetic resin films bonded to each other by an adhesive, or the window WIN can include a glass substrate to which the plastic film is bonded by an adhesive.

[0169] A window protective layer WP may be applied to a window WIN. The window protective layer WP may comprise a flexible plastic material, such as polyimide or polyethylene terephthalate. In some embodiments, one or more of a hard coating, an anti-fingerprint layer, and an anti-reflective layer may be applied to the top surface of the window protective layer WP.

[0170] The printed layer PIT can be on the bottom surface of the window protector WP. The printed layer PIT can be black, but there are no restrictions on the color of the printed layer PIT. The printed layer PIT can be adjacent to the edge of the window protector WP.

[0171] The fifth adhesive layer AL5 can be placed between the window protective layer WP and the window WIN. The fifth adhesive layer AL5 can attach the window protective layer WP to the window WIN. The fifth adhesive layer AL5 can cover the printed layer PIT.

[0172] The sixth adhesive layer AL6 can be placed between the window WIN and the anti-reflective layer RPL. The sixth adhesive layer AL6 can attach the window WIN to the anti-reflective layer RPL.

[0173] The seventh adhesive layer AL7 can be placed between the anti-reflective layer RPL and the display panel DP. The seventh adhesive layer AL7 can attach the anti-reflective layer RPL to the display panel DP.

[0174] The panel protective layer (PPL) is located beneath the display panel (DP). The PPL protects the lower portion of the display panel (DP). The PPL may comprise a flexible plastic material. For example, the PPL may comprise polyethylene terephthalate (PET).

[0175] The panel protective layer PPL may include a first PPL_1 below the first region AA1 and a second PPL_2 below the second region AA2. The panel protective layer PPL may not be below the bending region BA.

[0176] The barrier layer (BRL) is located beneath the panel protective layer (PPL). The BRL increases resistance to compressive forces caused by external suppression. Therefore, the BRL can be used to reduce or prevent deformation of the display panel (DP). The BRL may comprise a flexible plastic material, such as polyimide or polyethylene terephthalate.

[0177] The barrier layer (BRL) can have a light-absorbing color. The barrier layer (BRL) can be black. In this case, when viewed from above the display module (DM), the components beneath the barrier layer (BRL) are effectively invisible to the user.

[0178] The eighth adhesive layer AL8 may be located between the display panel DP and the panel protective layer PPL. The eighth adhesive layer AL8 may attach the display panel DP to the panel protective layer PPL. The eighth adhesive layer AL8 may include a first portion AL8_1 below the first region AA1 and a second portion AL8_2 below the second region AA2. The eighth adhesive layer AL8 may not be located below the curved region BA.

[0179] The ninth adhesive layer AL9 can be located between the barrier layer BRL and the first part PPL_1 of the panel protective layer PPL. The ninth adhesive layer AL9 can attach the barrier layer BRL to the first part PPL_1 of the panel protective layer PPL.

[0180] The tenth adhesive layer AL10 can be located between the barrier layer BRL and the first plate PLT1. The tenth adhesive layer AL10 can attach the barrier layer BRL to the first plate PLT1.

[0181] When viewed in a plan view, the tenth adhesive layer AL10 may include a first portion AL10_1 overlapping the first non-folded region NFA1, and a second portion AL10_2 overlapping the second non-folded region NFA2. The tenth adhesive layer AL10 may not overlap with the folded region FA. Because the tenth adhesive layer AL10 is not in the portion overlapping with the folded region FA, the first plate PLT1 can have increased flexibility.

[0182] The fifth adhesive layer AL5 to the tenth adhesive layer AL10 may include a transparent adhesive, such as a pressure-sensitive adhesive (PSA) or an optically transparent adhesive (OCA).

[0183] In some embodiments, the second release film RFL2 and the third release film RFL3 may then be removed, and the boundary adhesive layer BAD may be attached to the set structure that houses the display module DM and the support SUP.

[0187] The circuit element layer DP-CL may include a dielectric layer, semiconductor patterns, conductive patterns, and signal lines. A coating or deposition process can form the dielectric layer, semiconductor layer, and conductive layer on a substrate SUB. Subsequently, multiple photolithography processes can be performed, in which the dielectric layer, semiconductor layer, and conductive layer can be patterned to form semiconductor patterns, conductive patterns, and signal lines.

[0188] The circuit element layer DP-CL may include transistors formed by semiconductor patterns, conductive patterns, and signal lines. The display element layer DP-OLED may include light-emitting elements connected to the transistors. The transistors and light-emitting elements may be included in the pixels.

[0189] A thin-film encapsulation layer (TFE) can be placed on the circuit element layer (DP-CL) to cover the display element layer (DP-OLED). The TFE can include an inorganic layer, an organic layer, and another inorganic layer stacked sequentially. The inorganic layer can include inorganic materials and can protect the pixels from moisture and / or oxygen. The organic layer can include organic materials and can protect the pixels from impurities such as dust particles.

[0190] In some implementations, the input sensing unit (ISP) may include multiple sensors for detecting external inputs. The sensors may use capacitive methods to detect external inputs. External inputs may include a user's body part, light, heat, a pen, pressure, or various other types of external inputs.

[0191] When manufacturing a display panel DP, the input sensing unit ISP can be directly fabricated on the thin-film encapsulation layer TFE. However, this disclosure is not limited to this, and when manufacturing a display panel DP, the input sensing unit ISP can be fabricated separately in the form of a panel and then attached to the display panel DP by adhesive.

[0194] The first region AA1 may include a display region DA and a non-display region NDA surrounding the display region DA. The non-display region NDA may surround the display region DA (e.g., in a plan view). The display region DA may display an image, and the non-display region NDA may not display an image. In some embodiments, neither the second region AA2 nor the curved region BA displays an image.

[0195] When viewed in the second direction DR2, the first region AA1 may include a first non-folded region NFA1, a second non-folded region NFA2, and a folded region FA between the first non-folded region NFA1 and the second non-folded region NFA2.

[0197] The scan driver SDV and transmit driver EDV may be located in the non-display area NDA and may be adjacent to the corresponding opposite sides of the first area AA1 facing each other in the first direction DR1. The data driver DDV may be located in the second area AA2. The data driver DDV may be manufactured as an integrated circuit chip and may be mounted in the second area AA2.

[0198] Scan lines SL1 to SLm can extend in the first direction DR1 to connect to the scan driver SDV. Data lines DL1 to DLn can extend in the second direction DR2 to connect to the data driver DDV via the bend region BA. Transmit lines EL1 to ELm can extend in the first direction DR1 to connect to the transmit driver EDV.

[0199] The power line PL may extend in the second direction DR2 within the non-display area NDA. The power line PL may be between the display area DA and the transmit driver EDV, or between the display area DA and the scan driver SDV, but this disclosure is not limited thereto.

[0200] The power supply line PL can extend towards the second region AA2 and through the curved region BA. When viewed in a plan view, the power supply line PL can extend towards the bottom end of the second region AA2. The power supply line PL can receive the drive voltage.

[0201] The connecting line CNL can extend along the first direction DR1 and can be arranged along the second direction DR2. The connecting line CNL can be connected to the power line PL and the pixel PX. The driving voltage can be applied to the pixel PX through the power line PL and the connecting line CNL.

[0202] The first control line CSL1 can be connected to the scan driver SDV and can extend towards the bottom of the second region AA2 through the curved region BA. The second control line CSL2 can be connected to the transmit driver EDV and can extend towards the bottom of the second region AA2 through the curved region BA. The data driver DDV can be located between the first control line CSL1 and the second control line CSL2.

[0203] When viewed in a plan view, pad PD may be adjacent to the bottom of the second area AA2. Data driver DDV, power line PL, first control line CSL1, and second control line CSL2 may be connected to pad PD.

[0204] Data lines DL1 to DLn can be connected to the corresponding pads PD via the data driver DDV. For example, data lines DL1 to DLn can be connected to the data driver DDV, and the data driver DDV can be connected to the pads PD corresponding to the data lines DL1 to DLn.

[0205] In some implementations, a printed circuit board (PCB) may be provided connected to the pad PD. The timing controller and voltage generator may be located on the PCB. The timing controller may be manufactured as an integrated circuit chip and may be mounted on the PCB. The timing controller and voltage generator can be connected to the pad PD via the PCB.

[0206] The timing controller controls the operation of the scan driver (SDV), data driver (DDV), and transmit driver (EDV). In response to externally received control signals, the timing controller generates scan control signals, data control signals, and transmit control signals. A voltage generator generates drive voltages.

[0207] Scan control signals can be provided to the scan driver SDV via the first control line CSL1. Transmit control signals can be provided to the transmit driver EDV via the second control line CSL2. Data control signals can be provided to the data driver DDV. The timing controller can receive image signals from an external source (e.g., externally supplied image signals) and can convert the data format of the image signals to match the interface specifications of the data driver DDV, and can then provide the converted image signals to the data driver DDV.

[0208] In response to a scan control signal, the scan driver SDV generates multiple scan signals. These scan signals are applied to pixel PX via scan lines SL1 to SLm. The scan signals are applied to pixel PX sequentially. In response to a data control signal, the data driver DDV generates multiple data voltages corresponding to the image signal. These data voltages are supplied to pixel PX via data lines DL1 to DLn. In response to a transmit control signal, the transmit driver EDV generates multiple transmit signals. These transmit signals are applied to pixel PX via transmit lines EL1 to ELm.

[0209] In response to a scan signal, a data voltage can be provided to pixel PX. In response to a transmit signal, pixel PX can emit light corresponding to the data voltage, thereby displaying an image. The transmit signal can control the timing of light emission from pixel PX.

[0211] As an example, Figure 18 and Figure 20 It shows the relationship with Figure 9 The corresponding section of the cross section, and Figure 19 and Figure 21 It shows the relationship with Figure 12 The cross section corresponding to the cross section.

[0212] Reference Figure 18 The display module DM may include a first hole H1' corresponding to a first hole H1 defined by the support member SUP. The first hole H1' may be defined below the window WIN. The first hole H1' may be defined by an anti-reflective layer RPL, a display panel DP, a panel protective layer PPL, a barrier layer BRL, and a sixth adhesive layer AL6 to a tenth adhesive layer AL10.

[0213] Based on the first direction DR1 and the second direction DR2, the width of the first hole H1' defined by the barrier layer BRL, the ninth adhesive layer AL9, and the tenth adhesive layer AL10 can be greater than the width of the first hole H1' defined by the anti-reflective layer RPL, the display panel DP, the panel protective layer PPL, and the sixth adhesive layer AL6 to the eighth adhesive layer AL8.

[0214] Based on the first direction DR1 and the second direction DR2, the width of the first hole H1' defined by the anti-reflective layer RPL, the display panel DP, the panel protective layer PPL, and the sixth adhesive layer AL6 to the eighth adhesive layer AL8 can be smaller than the width of the first hole H1 defined by the first plate PLT1.

[0215] Based on the first direction DR1 and the second direction DR2, the width of the first hole H1' defined by the barrier layer BRL, the ninth adhesive layer AL9, and the tenth adhesive layer AL10 can be greater than the width of the first hole H1 defined by the first plate PLT1. Based on the first direction DR1 and the second direction DR2, the width of the first hole H1' defined by the barrier layer BRL, the ninth adhesive layer AL9, and the tenth adhesive layer AL10 can be less than the width of the first hole H1 defined by the boundary adhesive layer BAD, the step compensation layer CP, and the fourth adhesive layer AL4.

[0216] When viewed in a plan view, the first aperture H1' may overlap with the first aperture H1. In some embodiments, the camera (CAM) may be placed within the first aperture H1' and the first aperture H1 in a subsequent process.

[0217] In some embodiments, the second release film RFL2 and the support SUP can be vacuum-adsorbed onto the stage. Subsequently, when the display module DM is compressed toward and attached to the support SUP, the portion of the display module DM overlapping the first hole H1' can be recessed toward the first hole H1'. In this case, air can be discharged to the outside through the first cutting area INC1 from the first holes H1' and H1.

[0218] Reference Figure 19 The display module DM may include a second hole H2' corresponding to a second hole H2 defined by the support member SUP. The second hole H2' may be defined below the panel protective layer PPL. The second hole H2' may be defined by a barrier layer BRL and a ninth adhesive layer AL9 and a tenth adhesive layer AL10.

[0219] Based on the first direction DR1 and the second direction DR2, the width of the second hole H2' defined by the barrier layer BRL, the ninth adhesive layer AL9, and the tenth adhesive layer AL10 can be greater than the width of the second hole H2 defined by the first plate PLT1. Based on the first direction DR1 and the second direction DR2, the width of the second hole H2' defined by the barrier layer BRL, the ninth adhesive layer AL9, and the tenth adhesive layer AL10 can be less than the width of the second hole H2 defined by the boundary adhesive layer BAD, the step compensation layer CP, and the fourth adhesive layer AL4.

[0220] When viewed in a plan view, the second aperture H2' may overlap with the second aperture H2. In some embodiments, the sensor SN may be placed in the second aperture H2' and the second aperture H2 in a subsequent process.

[0221] When the display module DM is compressed toward and attached to the support SUP, the portion of the display module DM that overlaps with the second hole H2' can be recessed toward the second hole H2'. In this case, air can be discharged to the outside through the second cutting area INC2 from the second holes H2' and H2.

[0222] Reference Figure 20 and Figure 21 After the display module DM is attached to the support SUP, external air can be supplied to the first holes H1' and H1 through the first cutting area INC1. Therefore, the portion of the display module DM that overlaps with the first hole H1' can return to a flat state.

[0223] Furthermore, external air can be supplied to the second holes H2' and H2 through the second cutting zone INC2. Therefore, the portion of the display module DM that overlaps with the second hole H2' can return to a flat state.

[0224] When neither the first cutting area INC1 nor the second cutting area INC2 is formed, the second release film RFL2 can close or seal the first holes H1 and H1' and the second holes H2 and H2'. In this case, when the display module DM is compressed toward the support member SUP, the air pressure formed in the first holes H1 and H1' and the second holes H2 and H2' may prevent the attachment between the support member SUP and the portion of the display module DM surrounding the first hole H1' and the second hole H2'.

[0225] As air is discharged through the first cutting zone INC1 and the second cutting zone INC2, the first holes H1 and H1' and the second holes H2 and H2' can have low air pressure. Therefore, the display module DM can be properly attached to the support SUP.

[0226] When the display module DM is attached to the support member SUP, the portions of the display module DM at the first hole H1' and the second hole H2' can be recessed. However, after the display module DM is attached to the support member SUP, air can again be supplied to the first holes H1 and H1' and the second holes H2 and H2' through the first cutting area INC1 and the second cutting area INC2. Therefore, the portions of the display module DM that overlap with the first holes H1' and the second holes H2' can return to a flat state. In short, the display module DM will not deform.

[0227] refer to Figure 19 and Figure 21 External light can pass through the second release film RFL2 and then be supplied to the display panel DP through the second holes H2 and H2'. The photoelectric effect caused by the light can change the characteristics of the elements on the portions of the display panel DP with respect to the second holes H2 and H2'. In this case, when the display panel DP is operating, a brightness difference may occur between the portions of the display panel DP with respect to the second holes H2 and H2' and other portions of the display panel DP.

[0228] The light-shielding layer LSL blocks external light. Because the light-shielding layer LSL blocks external light, little or no external light can be supplied to the display panel DP through the second holes H2 and H2'.

[0229] Figure 22 The demonstration is shown Figure 15 The image depicts a cross-sectional view of the display panel in a curved state.

[0230] Reference Figure 22 , Figure 15 The second release film RFL2 and the third release film RFL3 can be removed, and then the bending region BA can be bent such that the second region AA2 is below the first region AA1. Therefore, the data driver DDV is below the first region AA1.

[0231] The spacer SPC may be located on the portion of the third release film RFL3 from which it is removed. The spacer SPC may be located below the first plate PLT1. The second portion PPL_2 of the panel protective layer PPL may be located below the spacer SPC.

[0232] The spacer SPC can be double-sided adhesive tape. For example, the spacer SPC may include a base layer such as flexible polyethylene terephthalate and adhesive on the top and bottom surfaces of the base layer. The second part PPL_2 of the panel protective layer PPL can be attached to the spacer SPC. Therefore, the display device DD can be as follows: Figure 22 As shown in the diagram.

[0233] The display device DD may include a protective layer BPL. The protective layer BPL may be in the curved region BA, in the portion of the first region AA1 adjacent to the curved region BA, and in the portion of the second region AA2 adjacent to the curved region BA. The protective layer BPL may extend from the portion of the first region AA1 adjacent to the curved region BA through the curved region BA toward the portion of the second region AA2 adjacent to the curved region BA.

[0234] The protective layer BPL can be used to protect the bending area BA. The protective layer BPL covers and protects the connecting lines within the bending area BA. The protective layer BPL supplements the rigidity of the bending area BA, and therefore prevents or reduces cracking in the bending area BA when it bends. The protective layer BPL protects the bending area BA from external impacts.

[0235] Figure 23 and Figure 24 A cross-sectional view showing a light-shielding layer according to some embodiments of the present disclosure is shown.

[0236] Figure 23 and Figure 24 The cross-section is shown as an example, with each section being... Figure 12 The cross-section corresponds to that.

[0237] Reference Figure 23 The light-shielding layer LSL' can be located on the bottom surface of the second sub-release film RFL2_2. The light-shielding layer LSL' can be attached to the bottom surface of the second sub-release film RFL2_2 by the adhesive ADH. The second cutting area INC2 can be defined in the light-shielding layer LSL', the adhesive ADH, and the second sub-release film RFL2_2.

[0238] Reference Figure 24 The light-shielding layer "LSL" can be applied to the bottom surface of the second sub-release film RFL2_2. For example, an inkjet printing process can be performed in which black ink can be printed on the bottom surface of the second sub-release film RFL2_2.

[0239] Figure 25 A plan view illustrating the construction of the cutting region according to some embodiments of the present disclosure is shown. Figure 26 It shows along Figure 25 The sectional view depicted by line IV-IV', and Figure 27 It shows along Figure 25 The sectional view is taken by the line V-V' depicted in the figure.

[0240] Figure 25 The second release film RFL2 is shown only as an example.

[0241] Reference Figure 25 and Figure 26The first cutting area INC1' may have a certain width and may be defined from the opening of the first part PT1 of the first sub-release film RFL2_1 that overlaps with the first hole H1 to the edge of the first sub-release film RFL2_1 adjacent to the first part PT1.

[0242] and Figure 9 Unlike the first cutting region INC1, the first cutting region INC1' may not be confined within the second release membrane RFL2_2. Furthermore, the first cutting region INC1' may be defined to extend in one direction without having a cross shape. The first cutting region INC1' may define an air passage (in... Figure 26 (represented by a double-headed arrow).

[0243] Reference Figure 25 and Figure 27 The second cutting area INC2' may have a certain width and may be defined from the opening of the second part PT2 of the first sub-release film RFL2_1 that overlaps with the second hole H2 to the edge of the first sub-release film RFL2_1 adjacent to the second part PT2.

[0244] and Figure 12 Unlike the second cutting region INC2, the second cutting region INC2' may not be confined within the second release membrane RFL2_2. Furthermore, the second cutting region INC2' may be defined as extending in one direction without having a cross shape. The second cutting region INC2' may define an air channel (in... Figure 27 (represented by a double-headed arrow).

[0245] According to some embodiments of this disclosure, the cutting area may be defined in the portion of the release film that overlaps with the hole defined by the support member. When the display module is attached to the support member, an air channel may be formed by the hole in the display module, the hole in the support member, and the cutting area. In summary, deformation of the upper portion of the display module that overlaps with the hole in the display module can be reduced or prevented.

[0246] Although this disclosure has been described in conjunction with some embodiments thereof, those skilled in the art will understand that this disclosure may be modified or altered in various ways without departing from the spirit and scope of this disclosure as defined by the appended claims. Furthermore, the embodiments disclosed herein are not intended to limit the technical spirit of this disclosure, and all technical spirit within the claims and their equivalents should be construed as being included in this disclosure.
