Detailed Implementation
[0030] Aspects of some embodiments of this disclosure and methods of implementing them can be more readily understood by referring to the detailed description and accompanying drawings of the embodiments. The described 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, redundant processes, elements, and techniques that are irrelevant or unrelated to the description of the embodiments, or that are not essential for a person of ordinary skill in the art to fully understand aspects of this disclosure, may be omitted. Unless otherwise stated, the same reference numerals, characters, or combinations thereof denote the same elements throughout the drawings and written description; therefore, repeated descriptions may be omitted.
[0031] The described embodiments may have various modifications and may be implemented in different forms, and should not be construed as being limited to the embodiments shown herein. In describing embodiments, the use of “may,” “can,” or “may not” corresponds to one or more embodiments of this disclosure.
[0032] Those skilled in the art will understand that, in view of the whole of this disclosure, each suitable feature of the various embodiments of this disclosure may be combined in part or in whole, or combined with each other, and may be technically interlocked and operated in a variety of suitable ways, and each embodiment may be implemented independently of each other or in combination with each other in any suitable way, unless otherwise stated or implied.
[0033] In the accompanying drawings, the relative dimensions of elements, layers, and regions may be exaggerated for clarity and / or descriptive purposes. In other words, the disclosure is not limited thereto because the dimensions and thicknesses of elements in the drawings are arbitrarily shown for ease of description. Furthermore, crosshairs and / or shading are typically provided in the drawings to clarify the boundaries between adjacent elements. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, scale, commonalities and / or any other characteristics, properties, etc., of the elements shown.
[0034] Various embodiments are described herein with reference to cross-sectional views that serve as schematic diagrams of examples and / or intermediate structures. Thus, variations in the illustrated shapes are contemplated due to factors such as 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 shapes shown for elements, layers, or regions, but rather include deviations in shape caused, for example, by manufacturing processes.
[0035] For example, an injection region shown as rectangular will typically have circular or curved features at its edges and / or a gradient of injection concentration, rather than a binary variation from the injection region to the non-injection region. Similarly, the buried region formed by injection may result in some injection in the region between the buried region and the surface through which the injection occurs.
[0036] For ease of description, spatial relative terms such as “below,” “under,” “lower,” “lower side,” “below,” “above,” “above,” “higher,” “upper side,” “side” (e.g., as in “sidewall”) may be used herein to describe the relationship of one element or feature to another, as shown in the accompanying drawings. It will be understood that, in addition to the orientations depicted in the drawings, the spatial relative terms are intended to cover different orientations of the device in use or operation. For example, if the device in the drawings is flipped, an element described as “below,” “under,” or “below” other elements or features will subsequently be oriented “above” said other elements or features. Thus, the example terms “below” and “below” can cover 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 the first part is described as being arranged "on" the second part, this means that the first part is arranged on the upper or lower side of the second part, and is not limited to the upper side of the second part based on the direction of gravity.
[0037] Furthermore, the phrase "in a plan view" means when viewing a portion of the object from above, and the phrase "in a schematic sectional view" means when viewing a schematic section taken by vertically cutting a portion of the object from the side. The term "overlay" or variations thereof means that the first object may be above, below, or to the side of the second object, or vice versa. Furthermore, the term "overlay" can include stacking, facing or oriented, extending over, covering or partially covering, or any other suitable term as will be understood and appreciated by one of ordinary skill in the art. The expression "not overlay" can include meanings such as "spaced apart from," "offset from," or "offset from," and any other suitable equivalent as will be understood and appreciated by one of ordinary skill in the art. The terms "facing" and "oriented" can mean that the first object may be directly or indirectly opposite the second object. In the case where a third object is placed between the first and second objects, the first and second objects, although still facing each other, can be understood as being indirectly opposite each other.
[0038] It will be understood that when an element, layer, region, or component (e.g., device, apparatus, circuit, wiring, electrode, terminal, conductive film, etc.) is referred to as being "formed on," "on," "connected to," or "(operably, functionally, or communicatively) incorporated into" another element, layer, region, or component, the element, layer, region, or component may be directly formed on, directly on, directly connected to, or directly incorporated into the other element, layer, region, or component, or indirectly formed on, indirectly on, indirectly connected to, or indirectly incorporated into the other element, layer, region, or component, such that one or more intermediary elements, layers, regions, or components may exist. Additionally, this can collectively mean direct (or indirect) incorporation (or connection) and integral (or non-integral) incorporation (or connection). For example, when a layer, region, or component is referred to as "electrically connected" or "electrically bonded" to another layer, region, or component, the layer, region, or component may be directly electrically connected or directly bonded to the other layer, region, and / or component, or one or more intermediary layers, regions, or components may be present. One or more intermediary components may include switches, transistors, resistors, inductors, capacitors, diodes, etc. Therefore, connections are not limited to those shown in the accompanying drawings or detailed descriptions, and may also include other types of connections. In describing embodiments, unless explicitly described as a direct connection, the expression for a connection indicates an electrical connection, and "directly connected / directly bonded" or "directly on" means that one component is directly connected to or directly bonded to another component, or directly on another component without any intermediate components.
[0039] Furthermore, in this specification, when a portion of a layer, film, region, plate, etc., is formed on another portion, the forming direction is not limited to the upward direction, but includes forming the portion on a side surface or in the downward direction. Conversely, when a portion of a layer, film, region, plate, etc., is formed "below" another portion, this includes not only the case where the portion is "directly" "below" the other portion, but also the case where there is another portion between the portion and the other portion. Similarly, other expressions describing relationships between components, such as "between," "immediately between," "adjacent to," and "directly adjacent to," can be interpreted similarly. It will be understood that when an element or layer is referred to as "between" two elements or layers, the element or layer may be the only element or layer between the two elements or layers, or there may be one or more intervening elements or layers.
[0040] For the purposes of this disclosure, expressions such as “at least one of…”, “any one of…”, or “one or more of…” modify the entire list of elements without modifying any individual element within that 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 only X, only Y, only Z, two or more of X, Y, and Z (e.g., XYZ, XY, YZ, and XZ) or any variation thereof. Similarly, the expression “at least one of A and B” can include A, B, or A and B. As used herein, “or” generally means “and / or”, and the term “and / or” includes any and all combinations of one or more of the associated listed items. For example, the expression “A and / or B” can include A, B, or A and B. Similarly, expressions such as “at least one of…”, “multiple…”, “one of…”, and other prepositional phrases modify the entire list of elements before (or after) it, without modifying any individual elements within that list. When stating “C to D”, unless otherwise specified, it means C or greater and D or less.
[0041] It will be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, layers, and / or parts should not be limited by these terms. These terms do not correspond to a particular order, position, or priority, and are used only to distinguish one element, component, assembly, region, area, layer, segment, or part from another. Therefore, without departing from the spirit and scope of this disclosure, the first element, component, region, layer, or segment described below may be referred to as a second element, component, region, layer, or segment. Describing an element as a “first” element does not require or imply the existence of a second element or other elements. The terms “first,” “second,” etc., may also be used herein to distinguish different categories or sets of elements. For the sake of brevity, the terms “first,” “second,” etc., may respectively represent “first category (or first set),” “second category (or second set),” etc.
[0042] 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.
[0043] The terminology used herein is for the purpose of describing embodiments only and is not intended to limit this disclosure. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “an” are intended to include the plural forms as well, and the plural forms are intended to include the singular forms as well. It will also be understood that when the terms “comprising,” “having,” and “including,” and “featuring,” are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof.
[0044] When one or more embodiments 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.
[0045] As used herein, the terms “basic,” “about,” “approximate,” and similar terms are used as approximate terms rather than as terms of degree and are intended to account for inherent deviations in measured or calculated values that would be recognized by one of ordinary skill in the art. For example, “basic” can include a range of + / - 5% of the corresponding value. As used herein, “about” or “approximate” includes the stated value and means: within an acceptable deviation range of the specific value as determined by one of ordinary skill in the art, taking into account the measurement under discussion and the errors associated with the measurement of the specific quantity (i.e., limitations of the measurement system). For example, “about” can mean within one or more standard deviations, or within ±30%, ±20%, ±10%, ±5% of the stated value. Furthermore, when describing embodiments of this disclosure, the use of “may” refers to “one or more embodiments of this disclosure.” Additionally, the expression “identical” can mean “substantially identical.” In other words, the expression “identical” can include a range that is tolerable by one of ordinary skill in the art. Other expressions may also be those from which “basic” has been omitted.
[0046] Unless otherwise defined, 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 field and / or in this specification, and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.

However, this disclosure should not be limited to or construed therein, and the shapes of the display area DA and the non-display area NDA may be varied.
[0050] In the following text, the direction substantially perpendicular to the plane defined by the first direction DR1 and the second direction DR2 may be referred to as the third direction DR3. The front and rear surfaces of each component of the electronic device ED may be distinguished from each other relative to the third direction DR3.

The folding axis can be substantially parallel to a first direction DR1 or a second direction DR2, and the folding area can be defined within a portion of the display area DA. The electronic device ED can fold inward (inward folding) to allow a portion of the display area DA to face another portion of the display area DA, or it can fold outward (outward folding) to allow a portion of the display area DA not to face another portion of the display area DA.

The pad area PA can be electrically bonded or connected to the flexible circuit board FCB, which will be described later. The pad area PA can be defined in the rear surface of the display panel DP.
[0058] Display panels (DPs) can have a generally quadrilateral shape. The term "generally quadrilateral shape" as used herein can refer not only to the mathematical concept of a rectangle, but also to a shape that resembles a rectangle and is perceived as such by the user. For example, a generally quadrilateral shape can include a quadrilateral shape with rounded corners. Furthermore, the edges of a display panel (DP) with a generally rectangular shape should not be limited to straight lines, and the edges may have curved areas.

The substrate BS may include a thin glass substrate, a protective film located on the thin glass substrate, and an adhesive layer to which the thin glass substrate and the protective film are attached.
[0066] The border pattern BM can be a colored light-blocking layer and can be formed through a coating process. The border pattern BM can include a base material and pigments or dyes mixed with the base material. The border pattern BM can be combined with... Figure 1 The non-display area NDA and shown Figure 2 The border region BZA shown is stacked. The border pattern BM can be located on the lower surface of the substrate BS. When the substrate BS has a multilayer structure, the border pattern BM can be located at the interface defined between the multiple layers. For example, the border pattern BM can be located between a thin glass substrate and a protective film. In one or more embodiments, the window WM can include at least one of a hard coating, an anti-fingerprint layer, and an anti-reflective layer located on the upper surface of the substrate BS.
[0067] The upper component UM may include the upper membrane UF. The upper membrane UF may include a synthetic resin membrane. The synthetic resin membrane may include polyimide, polycarbonate, polyamide, cellulose triacetate, polymethyl methacrylate, or polyethylene terephthalate.
[0068] The upper UF film can absorb external impacts applied to the front surface of the display device DD. According to one or more embodiments, the display module DM may include a color filter as an anti-reflective component instead of a polarizing film, and in this case, the impact resistance of the display device DD relative to external impacts applied to its front surface may be reduced. The upper UF film can compensate for the reduction in impact resistance relative to external impacts caused by applying a color filter to the display module DM.
[0069] The top film UF can be superimposed on the border region BZA and the transmission region TA. The top film UF can also be superimposed on only a portion of the border region BZA. A portion of the border pattern BM can be exposed and not covered by the top film UF. According to one or more embodiments, the top film UF can be omitted. According to one or more embodiments, the top film UF can be replaced by an optical film including a polarizer and a retarder.
[0070] The upper component UM may further include a first adhesive layer AL1 for attaching the upper film UF to the window WM and a second adhesive layer AL2 for attaching the upper film UF to the display module DM. The first adhesive layer AL1 and the second adhesive layer AL2 may be a pressure-sensitive adhesive (PSA) film or an optically clear adhesive (OCA). The adhesive layers described below may also include the same adhesive as the first adhesive layer AL1.
[0071] The display module DM can be located below the upper film UF. The display module DM can be overlaid with the border area BZA and the transmission area TA. The display module DM can be completely overlaid with the upper film UF within the border area BZA. When viewed in a plane, the side surface of the display module DM can be aligned with the side surface of the upper film UF, and the corners of the display module DM can be aligned with the corners of the upper film UF.
[0072] In the bezel area BZA, the pad area PA of the display module DM can be stacked with the upper film UF. The portion of the display module DM corresponding to the pad area PA can be bonded to the lower surface of the upper film UF through the second adhesive layer AL2. Because the pad area PA is stacked with the upper film UF and the portion of the display module DM that is stacked with the pad area PA is bonded to the upper film UF, the upper film UF can adequately support the pad area PA when the flexible circuit board FCB is bonded to the pad area PA.
[0073] The lower component LM may include the lower membrane PF, the cover plate CP, the third adhesive layer AL3, and the fourth adhesive layer AL4. The lower component LM may also include a support plate and a digitizer.
[0074] The lower film PF can be located below the display module DM and can be bonded to the lower surface of the display module DM via a third adhesive layer AL3. The lower film PF can protect the lower part of the display module DM. The lower film PF can include a flexible synthetic resin film. As an example, the lower film PF can include polyethylene terephthalate or polyimide. However, this disclosure should not be limited thereto or thereby restricted.
[0075] The lower film PF can expose at least the pad area PA of the display module DM. The lower film PF can have an area smaller than that of the display module DM. For example, the lower film PF can be superimposed only on the display area DA.
[0076] The lower film PF can have essentially the same dimensions as the display module DM. The lower film PF can be configured to correspond to the pad area PA (see reference). Figure 2 The opening area PF-OP. Even if the lower film PF completely protects the lower surface of the display module DM, the opening area PF-OP can be defined to allow the flexible circuit board FCB to approach the pad area PA.
[0077] like Figure 3 As shown, the lower film PF can be bonded to the cover panel CP via a fourth adhesive layer AL4. The cover panel CP can increase resistance to compressive forces caused by external pressure. Therefore, the cover panel CP can reduce or prevent deformation of the display module DM. The cover panel CP can include flexible plastic materials, such as polyimide or polyethylene terephthalate. Alternatively, the cover panel CP can be a colored film with low light transmittance. The cover panel CP can absorb light incident upon it from the outside. As an example, the cover panel CP can be a black synthetic resin film. When the display device DD is viewed from above the window WM, the components located under the cover panel CP are not visible to the user.
[0078] In one or more embodiments, the support plate may also be located below the cover panel CP. The support plate may include a high-strength metallic material. The support plate may include a fiber-reinforced composite material. The support plate may include reinforcing fibers located in the matrix portion. The reinforcing fibers may be carbon fiber or glass fiber. The matrix portion may include a polymer resin. The matrix portion may include a thermoplastic resin. As an example, the matrix portion may include a polyamide resin or a polypropylene resin. For example, the fiber-reinforced composite material may be carbon fiber reinforced plastic (CFRP) or glass fiber reinforced plastic (GFRP).

[0084] The light-emitting element layer 130 may be located on the driving element layer 120. The light-emitting element layer 130 may include light-emitting elements and transistors. For example, the light-emitting element may include organic light-emitting materials, inorganic light-emitting materials, organic-inorganic light-emitting materials, quantum dots, quantum rods, micro-LEDs, or nano-LEDs.

Encapsulation layer 140 may include at least one encapsulating inorganic layer. Encapsulation layer 140 may include a stacked structure in which a first encapsulating inorganic layer, an encapsulating organic layer, and a second encapsulating inorganic layer are sequentially stacked.
[0086] The input sensor ISL can be directly located on the display panel DP. The input sensor ISL can sense user input using either electromagnetic induction or capacitive methods. The display panel DP and the input sensor ISL can be formed through a continuous process. As used herein, the phrase "directly located on" can mean that there are no intermediate components between the input sensor ISL and the display panel DP. That is, a separate adhesive layer may not be required between the input sensor ISL and the display panel DP.

The first power supply voltage may be provided to the pixel PX via the first power line PL1, and the second power supply voltage may be provided to the pixel PX via the second power line PL2. Although multiple control signal lines CSL may be configured, in Figure 5 The diagram shows a control signal line CSL as a representative example.
[0093] Scan lines GL, data lines DL, and power lines PL can be stacked with the display area DP-DA and the non-display area DP-NDA, and control signal lines CSL can be stacked with the non-display area DP-NDA. Each of the signal lines GL can have a monolithic shape, but can include multiple portions located on different layers.

The pixel driving circuit PC can include multiple transistors S-TFT and O-TFT and capacitor Cst. Figure 6 The diagram shows silicon transistor S-TFT and oxide transistor O-TFT as representative examples of transistors. Figure 6 The pixel driving circuit PC is merely an example, and the components of the pixel driving circuit PC should not be limited to or restricted by it. The pixel driving circuit PC may consist of only one type of transistor, between silicon transistors (S-TFTs) and oxide transistors (O-TFTs).

Therefore, it can be ensured that the sixth insulating layer 60 covers the space at the boundary between the first pad conductive portion PCP1 and the first data conductive portion DCP1. When the sixth insulating layer 60 does not cover the boundary between the first pad conductive portion PCP1 and the first data conductive portion DCP1, the first bridge conductive pattern BCP1 may break due to the step difference between the first pad conductive portion PCP1 and the first data conductive portion DCP1, and the reliability of the display panel may deteriorate.

A portion of the second resin layer 110-B2 can be etched during the process of forming the first barrier opening BOP1, resulting in an over-etched area OEA that partially exposes the lower surface of the barrier layer 10br. When conductive material is applied to the second resin layer 110-B2 and the barrier layer 10br to form the first conductive pattern CP1, a separation portion CK can be formed between the first pad conductive portion PCP1 and the first data conductive portion DCP1 located on the second resin layer 110-B2 due to the over-etched area OEA. The separation portion CK can be a space that allows the first pad conductive portion PCP1 and the first data conductive portion DCP1 to be separated from each other. Due to the separation portion CK, the first pad conductive portion PCP1 and the first data conductive portion DCP1 can be non-electrically connected to each other or can be electrically insulated / separated. The separation portion CK can also be formed between the first additional conductive portion LCP1 and the first pad conductive portion PCP1.
