[0043] In the following description, numerous specific details are set forth for illustrative purposes to provide a thorough understanding of various exemplary embodiments or implementations of the invention. As used herein, “embodiment” and “implementation” are interchangeable terms and are non-limiting examples of apparatus or methods employing one or more inventive concepts disclosed herein. However, it will be apparent that various exemplary embodiments may be implemented 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 exemplary embodiments. Furthermore, the various exemplary embodiments may be different, but not necessarily exclusive. For example, a particular shape, construction, and characteristic of one exemplary embodiment may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0044] Unless otherwise stated, the exemplary embodiments shown are to be understood as exemplary features providing details of variations in some ways in which the inventive concept can be implemented in practice. Therefore, unless otherwise stated, features, components, modules, layers, films, panels, regions and / or aspects, etc. (hereinafter, individually or collectively referred to as “elements”) of various embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the inventive concept.

[0045] Crosshairs and / or shading are typically used in the accompanying drawings to clearly define 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, size, scale, commonalities between the elements shown, or any other characteristics, properties, etc. Furthermore, in the drawings, the dimensions and relative dimensions of elements may be exaggerated for clarity and / or descriptive purposes. A particular process sequence may be performed in a different order than that described when exemplary embodiments can be implemented differently. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Moreover, the same reference numerals denote the same elements.

[0046] When a component or layer is referred to as being "on" another component or layer, "connected to," or "bonded to" another component or layer, the component or layer may be directly on, directly connected to, or directly bonded to the other component or layer, or there may be intermediate components or layers present. However, when a component or layer is referred to as being "directly on" another component or layer, "directly connected to," or "directly bonded to" another component or layer, there are no intermediate components or layers present. Therefore, the term "connection" can refer to a physical connection, electrical connection, and / or fluid connection, with or without intermediate components. Furthermore, the DR1, DR2, and DR3 axes are not limited to the three axes of a Cartesian coordinate system such as the x, y, and z axes, but can be interpreted in a broader sense. For example, the DR1, DR2, and DR3 axes can be perpendicular to each other, or they can represent different directions that are not perpendicular to each other. For the purposes of this disclosure, “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 only X, only Y, only Z, or any combination of two or more of X, Y, and Z, such as XYZ, XYY, YZ, and ZZ. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items.

[0047] Although the terms “first,” “second,” etc., can be used here to describe various types of elements, these elements should not be limited by these terms. These terms are used to distinguish one element from another. Therefore, without departing from the publicly stated teachings, the first element discussed below can be referred to as the second element.

[0048] For descriptive purposes, spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” “side” (e.g., as in a “sidewall”) may be used herein to describe the relationship of one element to another, as shown in the accompanying drawings. Spatial relative terms are intended to include not only the orientations depicted in the drawings but also different orientations of the device in use, operation, and / or manufacture. For example, if the device in the drawings is flipped, an element described as “below” or “under” other elements or features will subsequently be oriented “above” said other elements or features. Thus, the exemplary term “below” can encompass both above and below orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or in other orientations), and thus, the spatial relative descriptive terms used herein are interpreted accordingly.

[0049] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, the terms “comprising,” “including,” and / or variations thereof, when used in this specification, indicate the presence of the stated features, integrals, steps, operations, elements, components, and / or groups thereof, but do not preclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, and are thus used to interpret inherent biases in measurements, calculations, and / or provided values ​​that will be recognized by those skilled in the art.

[0050] Various exemplary embodiments are described herein with reference to cross-sectional views and / or exploded views, which are schematic diagrams of idealized exemplary embodiments and / or intermediate structures. Thus, variations in the shapes of the illustrations, for example, due to manufacturing techniques and / or tolerances, will be expected. Therefore, the exemplary embodiments described herein should not necessarily be interpreted as limited to the shapes of the specifically shown areas, but rather to include, for example, deviations in shape due to manufacturing processes. In this way, the areas shown in the drawings can be schematic in nature, and the shapes of these areas may not reflect the actual shapes of the areas of the device, thus not necessarily intended to be limiting.

[0051] 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 is a part. Terms (such as those defined in a general dictionary) shall be interpreted as having the same meaning as they have in the context of the relevant field and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0052] In the following description, embodiments of the inventive concept will be illustrated with reference to the accompanying drawings.

[0053] Figure 1 This is a perspective view of a display device DD according to an embodiment of the inventive concept. Figure 2 This is a cross-sectional view of a display device DD according to an embodiment of the inventive concept.

[0054] like Figure 1 As shown, the display device DD can display the image IM via the display surface DD-IS. The display surface DD-IS is parallel to the plane defined by the first direction axis DR1 and the second direction axis DR2, and the second direction axis DR2 intersects the first direction axis DR1. The normal direction of the display surface DD-IS (i.e., the thickness direction of the display device DD) is indicated by the third direction axis DR3.

[0055] The front (or top) and rear (or bottom) surfaces of each of the components or members described below are distinguished by a third direction axis DR3. However, the first direction axis DR1, the second direction axis DR2, and the third direction axis DR3 shown in the exemplary embodiments are merely examples. Hereinafter, the first direction to the third direction is defined as the direction indicated by the first direction axis DR1, the second direction axis DR2, and the third direction axis DR3, respectively, and refers to the same reference numerals.

[0056] An exemplary embodiment of the inventive concept shows a display device DD having a flat display surface, but embodiments of the inventive concept are not limited thereto. The display device DD may include a curved display surface. The display device DD may include a three-dimensional display surface. The three-dimensional display surface has display areas indicating different directions and may include, for example, a polygonal prism-shaped display surface.

[0057] The display device DD according to an exemplary embodiment may be a rigid display device. However, embodiments of the inventive concept are not limited thereto, and the display device DD according to the embodiment may be a flexible display device. A flexible display device may include a foldable display device that can be folded and a bendable display device in which a portion is bent.

[0058] In an exemplary embodiment, Figure 1 The diagram illustrates a display device DD that can be used in a mobile terminal. Although not shown, electronic modules, camera modules, power modules, etc., mounted on the motherboard are housed together with the display device DD in a bracket / housing, etc., thus constituting a mobile terminal. The display device DD according to embodiments of the inventive concept can be used in large-sized electronic devices such as televisions and monitors, as well as in small-to-medium-sized electronic devices such as tablet computers, vehicle navigation devices, game consoles, and smartwatches.

[0059] like Figure 1 As shown, the display surface DD-IS includes an image area DD-DA on which an image IM is displayed, and a border area DD-NDA adjacent to the image area DD-DA. The border area DD-NDA is the area on which no image is displayed. Figure 1 In the image, the application icon is shown as an example of an IM.

[0060] like Figure 1 As shown, the image region DD-DA can have a substantially quadrilateral shape. "Substantially quadrilateral shape" can include not only quadrilateral shapes in a mathematical sense, but also quadrilateral shapes in vertex regions (corner regions) that do not define vertices but define curved boundaries.

[0061] The border region DD-NDA may surround the image region DD-DA. However, embodiments of the inventive concept are not limited to this, and the shapes of the image region DD-DA and the border region DD-NDA may be designed to other shapes. The border region DD-NDA may be disposed only on one side of the image region DD-DA. Depending on the bonding state between the display device DD and other components of the electronic device (not shown), the border region DD-NDA may not be exposed to the outside.

[0062] A display device DD according to an exemplary embodiment of the inventive concept can sense user input TC applied externally. The user input TC can be one or a combination of various external inputs, such as a tool (e.g., a stylus) or a part of the user's body. The display device DD senses changes in one or a combination of reflected light, temperature, pressure, ultrasound, and electromagnetic fields caused by the user input TC, and thus can sense the user input TC. The user input TC shown in the exemplary embodiment is assumed to be tactile input by the user's hand applied to the front surface of the display device DD. However, this is merely an example, and the user input TC can be provided in various forms as described above. Furthermore, the display device DD can also sense user input TC applied to the side or bottom surface of the display device DD based on the structure of the display device DD, but is not limited to one embodiment.

[0063] Figure 2 A cross-section of the display device DD, defined by a first directional axis DR1 and a third directional axis DR3, is shown. Figure 2 The components of the display device DD are schematically shown to explain their stacking relationship.

[0064] A display device DD according to an exemplary embodiment of the inventive concept may include a display panel DP, an input sensing layer ISL, an antireflector RPP, and a window WP. At least some of the components of the display panel DP, the input sensing layer ISL, the antireflector RPP, and the window WP may be formed by a continuous process, or at least some of the components may be bonded together by an adhesive member ADS. The adhesive member ADS may be a pressure-sensitive adhesive film (PSA) or a transparent adhesive member, such as an optically transparent adhesive film (OCA) or an optically transparent resin (OCR). The adhesive members described below may include general adhesives or bonding agents. In an exemplary embodiment of the inventive concept, the antireflector RPP and the window WP may be replaced by other components or omitted.

[0065] exist Figure 2In the process described, among the input sensing layer ISL, anti-reflective RPP, and window WP, the input sensing layer ISL is formed together with the display panel DP through a continuous process and is directly disposed on the display panel DP. In the specification, "component B is directly disposed on component A" means that there is no separate adhesive layer / adhesive component between component A and component B. After component A is formed, component B is formed on the substrate surface provided by component A through a continuous process.

[0066] In an exemplary embodiment, the antireflector RPP and window WP can be of the "panel" type, and the input sensing layer ISL can be of the "layer" type. The "panel" type includes a substrate layer (such as a synthetic resin film, composite film, and glass substrate) providing a substrate surface, but the "layer" type may not have a substrate layer. That is, the "layer" type component is disposed on a bottom surface provided by other components. In an exemplary embodiment of the inventive concept, the antireflector RPP and window WP can be of the "layer" type.

[0067] The display panel DP generates an image, and the input sensing layer ISL acquires coordinate information about external inputs (e.g., touch events). Although not shown separately, the display device DD according to an exemplary embodiment of the inventive concept may also include a protective member disposed on the bottom surface of the display panel DP. The protective member and the display panel DP may be bonded to each other by an adhesive member.

[0068] The display panel DP according to exemplary embodiments of the inventive concept can be a light-emitting display panel, but is not specifically limited thereto. For example, the display panel DP can be an organic light-emitting display panel or a quantum dot light-emitting display panel. These panels can be classified according to the materials constituting the light-emitting elements. The light-emitting layer of an organic light-emitting display panel may include organic light-emitting materials. The light-emitting layer of a quantum dot light-emitting display panel may include quantum dots and / or quantum rods. Hereinafter, the display panel DP is described as an organic light-emitting display panel.

[0069] An antireflective refractive power plate (RPP) can reduce the reflectivity of external light incident from the upper side of a window (WP). An exemplary embodiment of the antireflective RPP according to the inventive concept may include a phase retarder and a polarizer. The phase retarder may be a film-type or a liquid crystal-coated type, and may include a λ / 2 phase retarder and / or a λ / 4 phase retarder. The polarizer may also be a film-type or a liquid crystal-coated type. A film-type may include an elongated synthetic resin film, and a liquid crystal-coated type may include liquid crystals arranged in a predetermined configuration. The phase retarder and polarizer may also include a protective film. The phase retarder and polarizer themselves or the protective film may be defined as a substrate layer of the antireflective RPP.

[0070] An antireflective reflector RPP according to an exemplary embodiment of the inventive concept may include a color filter. The color filter has a predetermined arrangement. The arrangement of the color filter can be determined by considering the emission colors of the pixels included in the display panel DP. The antireflective reflector RPP may also include a black matrix adjacent to the color filter.

[0071] An antireflector RPP according to an exemplary embodiment of the inventive concept may include a destructive interference structure. For example, the destructive interference structure may include a first reflective layer and a second reflective layer disposed on different layers. First reflected light and second reflected light reflected from the first reflective layer and the second reflective layer, respectively, can be destructively interfered with, thus reducing the reflectivity of external light.

[0072] A window WP according to exemplary embodiments of the inventive concept may include a glass substrate and / or a synthetic resin film. The window WP is not limited to a single layer. The window WP may include two or more films bonded together by adhesive members. Although not shown separately, the window WP may also include a functional coating. The functional coating may include an anti-fingerprint layer, an anti-reflective layer, and a hard coating.

The DP-OLED light-emitting element layer may also include an organic layer such as a pixel defining layer.

[0078] A thin-film encapsulation layer (TFE) can be deposited on the DP-OLED light-emitting element layer to cover it. The TFE can completely cover the active area (AA). Alternatively, the TFE can cover a portion of the peripheral area (NAA).

[0079] The thin-film encapsulation layer TFE comprises thin films. Some thin films are provided to improve optical efficiency, and other thin films are provided to protect the organic light-emitting diode.

[0084] The signal line SGL includes scan line SL, data line DL, power line PL, light emission control line EL, and control signal line CSL. Each of the scan line SL, data line DL, and light emission control line EL is connected to the corresponding pixel PX. The power line PL is collectively connected to pixel PX. The control signal line CSL provides control signals to the scan drive circuit SDC. The power line PL provides the voltage required for the operation of pixel PX. The power line PL may include multiple lines providing different voltages.

[0085] In an exemplary embodiment, the signal line SGL may further include an auxiliary line SSL. The auxiliary line SSL may be connected to the input sensing layer ISL (see...). Figure 2 The signal line is a signal line. In embodiments of the inventive concept, the auxiliary line SSL can be omitted. The auxiliary line SSL can be connected to the contact hole CNT. The auxiliary line SSL can be connected to the input sensing layer ISL (see below) which will be described later via the contact hole CNT. Figure 6 (Signal line)

[0086] Signal pads DP-PD and ISL-PD may include a first type of signal pad DP-PD connected to the data line DL, power line PL, and control signal line CSL, and a second type of signal pad ISL-PD connected to the auxiliary line SSL. The first type of signal pad DP-PD and the second type of signal pad ISL-PD are arranged adjacent to each other in a pad region NDA-PA defined within a portion of the peripheral region NAA. The stacked structure or composition of the signal pads DP-PD and ISL-PD may be indistinguishable from each other and formed using the same process.

[0087] The effective area AA can be defined as the area in which pixels PX are disposed. Multiple electronic components are disposed within the effective area AA. These electronic components include an organic light-emitting diode disposed in each pixel PX and a pixel driving circuit connected thereto. The scan driving circuit SDC, signal line SGL, signal pads DP-PD and ISL-PD, and the pixel driving circuit may be included. Figure 3 The circuit element layer DP-CL is shown in the diagram.

[0088] Although not shown in the accompanying drawings, each of the pixels PX may include multiple transistors, capacitors, and organic light-emitting diodes. The pixel PX emits light in response to signals received via the scan line SL, data line DL, light emission control line EL, and power line PL.

[0089] The signal pads DP-PD and ISL-PD of the display panel DP can be electrically connected to a printed circuit board not shown in the attached diagram.

[0090] exist Figure 4 A portion of the display panel DP shown is bendable. A portion of the peripheral area NAA of the display panel DP is bendable. The portion can be bent about a bending axis parallel to a first direction DR1. The bending axis can be defined as overlapping some of the data lines DL and some of the auxiliary lines SSL.

[0091] Figure 5 This is a cross-sectional view of the display panel DP and the input sensing layer ISL of a display device DD according to an embodiment of the inventive concept. The display panel DP is shown schematically to illustrate the stacking relationship of the input sensing layer ISL.
