[0049] In this specification, when it is mentioned that a certain component (or region, layer, part, etc.) is "above", "connected" to, or "combined" with another component, it means that it can be directly arranged on or directly connected / combined with another component, or a third component can be arranged between them.

[0050] The same reference numerals refer to the same constituent elements. Furthermore, in the drawings, the thickness, proportions, and dimensions of the constituent elements are exaggerated for the purpose of effective illustration of the technical content. "And / or" includes all but one combination of the related constituent elements that can be defined.

[0051] The terms "first," "second," etc., can be used to describe multiple constituent elements, but the constituent elements should not be limited by the terms. The terms are used only to distinguish one constituent element from another. For example, without departing from the scope of the invention, a first constituent element can be named a second constituent element, and similarly, a second constituent element can be named a first constituent element. Singular expressions include plural expressions as long as the context does not explicitly indicate a different meaning.

[0052] Furthermore, terms such as "below," "lower side," "above," and "upper side" are used to describe the relationships between the components shown in the accompanying drawings. These terms are relative concepts and are explained based on the directions indicated in the accompanying drawings.

[0053] Terms such as “including” or “having” should be understood as: used to specify the presence of features, figures, steps, operations, constituent elements, components or combinations thereof described in the specification, rather than precluding the presence or possibility of one or more other features or figures, steps, operations, constituent elements, components or combinations thereof.

[0054] Unless otherwise defined, all terms (including technical and scientific terms) used in this specification shall have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Furthermore, terms identical to those defined in commonly used dictionaries shall be interpreted as having the same meaning as in the context of the relevant art, and are hereby expressly defined unless interpreted as having an ideal or overly formal meaning.

[0055] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0056] Figure 1 This is a perspective view of a display device DD according to an embodiment of the present invention. Figure 2 This is a cross-sectional view of a display device DD according to an embodiment of the present invention.

[0057] like Figure 1 As shown, the display device DD can display the image IM through 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. 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.

[0058] The front (or upper surface) and back (or lower surface) of each component or unit 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 illustrated in this embodiment are merely examples. Hereinafter, the direction from the first direction to the third direction will be defined as the direction indicated by the first direction axis DR1, the second direction axis DR2, and the third direction axis DR3, respectively, and will be referred to by the same reference numerals.

[0059] In one embodiment of the present invention, a display device DD equipped with a planar display surface is illustrated; however, it is not limited thereto. The display device DD may also include a curved display surface. The display device DD may also include a three-dimensional display surface. A three-dimensional display surface may include multiple display areas indicating different directions, for example, it may also include a polygonal prism-shaped display surface.

[0060] The display device DD according to this embodiment can be a rigid display device. However, it is not limited thereto; the display device DD according to the present invention can be a flexible display device. A flexible display device can include a foldable flexible display device or a curved display device with a portion of its area bent.

[0061] In this embodiment, Figure 1 An exemplary illustration shows a display device DD applicable to a portable terminal. Although not shown, electronic modules, camera modules, power modules, etc., mounted on a motherboard, are arranged together with the display device DD on a bracket / housing, etc., to form a portable telephone terminal. The display device DD according to the present invention can be applied to large electronic devices such as televisions and monitors, as well as small and medium-sized electronic devices such as tablet computers, car navigation systems, game consoles, and smartwatches.

[0062] like Figure 1 As shown, the display surface DD-IS includes the image area DD-DA that displays the image IM and the border area DD-NDA adjacent to the image area DD-DA. The border area DD-NDA is the area where no image is displayed. Figure 1 The illustration shows an example of an icon image used as an image IM.

[0063] like Figure 1 As shown, the image region DD-DA can essentially be a quadrilateral shape. "Essentially a quadrilateral shape" includes not only quadrilateral shapes in the mathematical sense, but also quadrilateral shapes with curved boundaries that are not defined at vertex regions (or corner regions).

[0064] The border area DD-NDA may surround the image area DD-DA. However, it is not limited to this; the image area DD-DA and the border area DD-NDA may be designed in other shapes. The border area DD-NDA may also be arranged only on one side of the image area DD-DA. Depending on the combination of the display device DD with other components of the electronic device, the border area DD-NDA may not be exposed to the outside.

[0065] According to an embodiment of the present invention, the display device DD can sense a first user input TC1 applied from the outside. The first user input TC1 can be any one or a combination of various forms of external input, such as a part of the user's body, light, heat, and pressure. In this embodiment, it is assumed that the first user input TC1 is a touch input caused by a user's hand applied to the front; however, this is merely exemplary, and as described above, the first user input TC1 can be provided in various forms. Furthermore, the display device DD can also sense the first user input TC1 applied to the side or back of the display device DD, depending on the structure of the display device DD, and is not limited to any particular embodiment.

[0066] Furthermore, according to an embodiment of the present invention, the display device DD can sense a second input TC2 applied from the outside. The second input TC2 includes input from electronic input devices other than the user's hand (stylus, stylus, electronic pen, reading pen, etc.). In the following description, it is assumed that the second input TC2 is input from an electronic pen EP. The electronic pen EP includes a tip TP made of conductive material. The display device DD can sense the second input TC2 by sensing the resonance (electromagnetic resonance (EMR)) caused by the electromagnetic induction between the magnetic field generated internally and the tip TP of the electronic pen EP.

[0067] Figure 2 The diagram illustrates a cross-section of the display device DD defined by the first directional axis DR1 and the third directional axis DR3. Figure 2 In order to illustrate the stacking relationship of the components of the display device DD, the components of the display device DD are simply illustrated.

[0068] A display device DD according to an embodiment of the present invention may include a display panel DP, an input sensor ISL, an anti-reflector RPP, and a window WP. At least some of the components of the display panel DP, the input sensor ISL, the anti-reflector 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 component. The adhesive component ADS may be a transparent adhesive component such as a pressure-sensitive adhesive film (PSA), an optically clear adhesive film (OCA), or an optically clear resin (OCR). The adhesive components described below may include conventional adhesives or bonding agents. In one embodiment of the present invention, the anti-reflector RPP and the window WP may be replaced or omitted by other components.

[0069] exist Figure 2 In this design, the input sensor ISL, the anti-reflection component RPP, and the input sensor ISL in the window WP, which are formed in a continuous process with the display panel DP, are directly disposed on the display panel DP. In this specification, "Component B is directly disposed on Component A" means that no additional adhesive layer / adhesive component is disposed between Component A and Component B. After Component A is formed, Component B is formed on the base surface provided by Component A through a continuous process.

[0070] In this embodiment, the anti-reflector RPP and window WP are of the "panel" type, and the input sensor ISL is of the "layer" type. While the "panel" type includes a base layer (e.g., a synthetic resin film, composite film, glass substrate, etc.) providing the substrate, the "layer" type may omit the base layer. In other words, the components of the "layer" type are arranged on a base surface provided with other components. In one embodiment of the invention, the anti-reflector RPP and window WP may also be of the "layer" type.

[0071] The display panel DP generates an image, and the input sensor ISL acquires coordinate information of external inputs (e.g., touch events). Although not shown separately, the display device DD according to an embodiment of the present invention may further include a protective member disposed on the lower surface of the display panel DP. The protective member and the display panel DP may be bonded together by an adhesive member.

[0072] According to an embodiment of the present invention, the display panel DP can be a light-emitting display panel, and is not particularly limited thereto. For example, the display panel DP can be an organic light-emitting display panel or a quantum dot light-emitting display panel. The panel is distinguished according to the constituent material of the light-emitting element. The light-emitting layer of an organic light-emitting display panel may include an organic light-emitting material. The light-emitting layer of a quantum dot light-emitting display panel may include quantum dots and / or quantum rods, etc. Hereinafter, the display panel DP will be described as an organic light-emitting display panel.

[0073] The anti-reflection component RPP reduces the reflectivity of external light incident from the upper side of the window WP. According to an embodiment of the present invention, the anti-reflection component RPP may include a phase retarder and a polarizer. The phase retarder may be a film-type or 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 liquid crystal-coated type. The film-type may include an extended synthetic resin film, and the liquid crystal-coated type includes liquid crystals arranged in a predetermined pattern. 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 the base layer of the anti-reflection component RPP.

[0074] A reflection-prevention component RPP according to an embodiment of the present invention may include color filters. The color filters have a predetermined arrangement. The arrangement of the color filters may be determined taking into account the emission colors of the pixels included in the display panel DP. The reflection-prevention component RPP may also include a black matrix adjacent to the color filters.

[0075] A reflection prevention component RPP according to an embodiment of the present invention may include a destructive interference structure. For example, the destructive interference structure may include a first reflective layer and a second reflective layer arranged on different layers. The first reflected light and the second reflected light reflected by the first reflective layer and the second reflective layer, respectively, can destructively interfere, thereby reducing the external light reflectivity.

[0076] According to an embodiment of the present invention, the window WP includes a base layer WP-BS and a light-blocking pattern WP-BZ. The base layer WP-BS may include a glass substrate and / or a synthetic resin film, etc. The base layer WP-BS is not limited to a single layer. The base layer WP-BS may include two or more films bonded together by an adhesive component.

[0077] The light-blocking pattern WP-BZ partially overlaps with the base layer WP-BS. The light-blocking pattern WP-BZ is located on the back side of the base layer WP-BS, and it substantially defines the bezel area DD-NDA of the display device DD. The area where the light-blocking pattern WP-BZ is not located defines the image area DD-DA of the display device DD. If the window WP is defined, the area where the light-blocking pattern WP-BZ is located is defined as the light-blocking area of ​​the window WP, and the area where the light-blocking pattern WP-BZ is not located is defined as the transmissive area of ​​the window WP.

[0078] The light-blocking pattern WP-BZ can have a multi-layered structure. This multi-layered structure can include a colored layer and a colorless (especially black) light-blocking layer. The colored layer and the colorless light-blocking layer can be formed through deposition, printing, or coating processes. Although not shown separately, the window WP can also include a functional coating layer disposed in front of the base layer WP-BS. This functional coating layer can include an anti-fingerprint layer, an anti-reflective layer, and a hard coating, etc.

[0079] Figure 3 This is a cross-sectional view of a display panel DP according to an embodiment of the present invention. Figure 4 This is a plan view of a display panel DP according to an embodiment of the present invention.

(The last sentence appears to be incomplete and possibly refers to a different display panel.) Figure 1 The image area DD-DA and the border area DD-NDA shown correspond to the display area DP-DA and the non-display area DP-NDA, which can be defined on the display panel DP. In this specification, "area / part corresponding to area / part" means "overlapping", but is not limited to having the same area and / or the same shape.

[0086] The driving circuit SDC may include a scan driving circuit. The scan driving circuit generates multiple scan signals (hereinafter referred to as "scan signals") and outputs the scan signals sequentially to multiple scan lines GL (hereinafter referred to as "scan lines") as described below. The scan driving circuit may also output another control signal to the driving circuit of pixel PX.

[0087] The scan driving circuit may include multiple thin-film transistors formed using the same process as the driving circuit of the pixel PX (e.g., low-temperature polycrystalline silicon (LTPS) process or low-temperature polycrystalline oxide (LTPO) process).

[0088] The signal line SGL may include scan lines GL, data lines DL, power lines PL, and control signal lines CSL. Scan lines GL are connected to corresponding pixels PX, and data lines DL are connected to corresponding pixels PX. Power lines PL are connected to pixels PX. Control signal lines CSL provide control signals to the scan drive circuit.

[0089] In this embodiment, the signal line SGL may further include an auxiliary line SSL. The auxiliary line SSL is connected to the input sensor ISL (see reference). Figure 2The signal line (SSL). In one embodiment of the invention, the auxiliary line SSL can be omitted.

[0090] Signal lines (SGLs) can include multiple parts arranged on different layers. Figure 4 An exemplary illustration shows a data line DL comprising four parts P1, P2, P3, and P4, and an auxiliary line SSL comprising two parts P10 and P20. The four parts P1, P2, P3, and P4 can be connected via contact holes CNT, and the two parts P10 and P20 can be connected via contact holes CNT. The first part P10 of the auxiliary line SSL is connected via contact hole CNT to the input sensor ISL (see reference 1) described later. Figure 6 (Signal line connection).

[0091] Signal pads DP-PD and ISL-PD may include a first type of signal pad DP-PD connected to data line DL, power line PL, and control signal line CSL, and a second type of signal pad ISL-PD connected to 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 non-display area DP-NDA. The pad region NDA-PA may be adjacent to the edge DP-E of the display panel DP. The stacked structure or constituent materials of the signal pads DP-PD and ISL-PD may be indistinguishable from each other and may be formed using the same process.

[0092] The display area DP-DA can be defined as an area where pixels PX are arranged. Multiple electronic components are arranged in the display area DP-DA. These electronic components include an organic light-emitting diode (OLED) equipped in each pixel PX and a pixel driving circuit connected thereto.

The circuit board PCB may include a circuit board pad PCB-P electrically connected to signal pads DP-PD and ISL-PD. Although not shown, the circuit board PCB also includes signal lines connecting the circuit board pad PCB-P to the panel control circuit PC and / or the input sensing circuit ISL-C. Furthermore, the circuit board pad PCB-P may include at least one output pad and at least one input pad.

[0096] The signal pads DP-PD and ISL-PD of the display panel DP can be directly connected to the circuit board pad PCB-P. In another embodiment, the signal pads DP-PD and ISL-PD can be electrically connected to the circuit board pad PCB-P via a connection substrate such as an anisotropic conductive film.

[0097] In another embodiment, the panel control circuit PC can be mounted on the non-display area DP-NDA of the display panel DP, instead of being mounted on the circuit board PCB.

[0098] Figure 4 The display panel DP shown can be partially bent. A portion of the non-display area DP-NDA can be bent, with a bending axis parallel to the second direction DR2 as a reference. The bending axis can be defined as overlapping with the third portion P3 of the data line DL and the first portion P10 of the auxiliary line SSL.

[0100] Reference Figure 5aThe display panel (DP) can include multiple insulating layers, as well as semiconductor patterns, conductive patterns, signal lines, etc. Insulating layers, semiconductor layers, and conductive layers are formed through coating, deposition, or other methods. Subsequently, the insulating layers, semiconductor layers, and conductive layers can be selectively patterned using photolithography. This process forms the semiconductor patterns, conductive patterns, signal lines, etc., included in the circuit element layer (DP-CL) and the display element layer (DP-OLED).

[0101] The base layer BL may include a synthetic resin layer. The synthetic resin layer may include a thermosetting resin. The base layer BL may have a multilayer structure. For example, the base layer BL may also have a three-layer structure consisting of a synthetic resin layer, an adhesive layer, and a synthetic resin layer. In particular, the synthetic resin layer may be a polyimide resin layer, and the material is not particularly limited. The synthetic resin layer may include at least one of acrylic resins, methacrylic resins, polyisoprene, ethylene resins, epoxy resins, urethane resins, cellulose resins, siloxane resins, polyamide resins, and dinaphthalene-based resins.

A semiconductor pattern can include doped and undoped regions. Doped regions can be doped with N-type or P-type dopants. A P-type transistor includes a doped region doped with P-type dopants.

[0106] Doped regions have higher conductivity than undoped regions and essentially function as electrodes or signal lines.

A hole control layer (HCL) and the ECL may be co-formed on multiple pixels using an open mask. A second electrode (CE) is disposed on the ECL. The second electrode (CE) has a monolithic shape and is co-located on multiple pixels (PX) (see reference). Figure 4 ).

[0118] like Figure 5a and Figure 5b As shown, an upper insulating layer TFL is disposed on the second electrode CE. The upper insulating layer TFL may include multiple thin films.

The first input insulating layer ISL-IL1 is directly disposed on the upper insulating layer TFL. In one embodiment of the present invention, the first input insulating layer ISL-IL1 may be omitted.

[0125] The first conductive layer ISL-CL1 and the second conductive layer ISL-CL2 can each have a single-layer structure or a multilayer structure stacked along a third directional axis DR3.

[0128] Figure 7a This is a plan view of an input sensor ISL according to an embodiment of the present invention. Figure 7b It is shown in magnification Figure 7a The diagram shows the first region AA of the input sensor ISL. Figure 7c and Figure 7d This is a partial cross-sectional view of an input sensor ISL according to an embodiment of the present invention.

[0129] like Figure 7a and Figure 7b As shown, the input sensor ISL includes first sensing electrodes IE1-1 to IE1-10, second sensing electrodes IE2-1 to IE2-8, first connecting lines CNL1-1 to CNL1-5, second connecting lines CNL2-1 to CNL2-4, first sensing lines SL1-1 to SL1-10, and second sensing lines SL2-1 to SL2-8. The input sensor ISL may include a sensing area ISL-DA and a wiring area ISL-NDA corresponding to the display area DP-DA and the non-display area DP-NDA of the display panel DP, respectively. The sensing area ISL-DA can be defined as the area where the first sensing electrodes IE1-1 to IE1-10 and the second sensing electrodes IE2-1 to IE2-8 are arranged. The first connecting lines CNL1-1 to CNL1-5, the second connecting lines CNL2-1 to CNL2-4, the first sensing lines SL1-1 to SL1-10, and the second sensing lines SL2-1 to SL2-8 are arranged in the wiring area ISL-NDA.

[0130] In this embodiment, the input sensor ISL can be a capacitive touch sensor. One of the first sensing electrodes IE1-1 to IE1-10 and the second sensing electrodes IE2-1 to IE2-8 receives a drive signal, while the other outputs the capacitance change between the first sensing electrodes IE1-1 to IE1-10 and the second sensing electrodes IE2-1 to IE2-8 as a sensing signal.

[0131] Each of the first sensing electrodes IE1-1 to IE1-10 has a shape extending along the second direction DR2. Furthermore, the first sensing electrodes IE1-1 to IE1-10 can be arranged sequentially along the first direction DR1.

[0132] Each of the second sensing electrodes IE2-1 to IE2-8 has a shape extending along the first direction DR1. Furthermore, the second sensing electrodes IE2-1 to IE2-8 can be arranged sequentially along the second direction DR2.

[0133] The first sensing lines SL1-1 to SL1-10 may include the same number of signal lines as the first sensing electrodes IE1-1 to IE1-10. The first sensing lines SL1-1 to SL1-10 may be connected to at least one of the two ends of the first sensing electrodes IE1-1 to IE1-10. The second sensing lines SL2-1 to SL2-8 may include the same number of signal lines as the second sensing electrodes IE2-1 to IE2-8. The second sensing lines SL2-1 to SL2-8 may be connected to at least one of the two ends of the second sensing electrodes IE2-1 to IE2-8.

[0134] The first sensing lines SL1-1 to SL1-10 can be connected via contact holes CNT to the auxiliary lines SSL arranged on one side of the pad area NDA-PA (see reference). Figure 4 A portion of the second sensing lines SL2-1 to SL2-8 can be connected via contact holes CNT to auxiliary lines SSL arranged on the other side of the pad area NDA-PA (see reference). Figure 4 (a part of the connection).

[0135] The contact hole CNT penetrates the insulating layer arranged between the first sensing lines SL1-1 to SL1-10 and the second sensing lines SL2-1 to SL2-8 and the auxiliary line SSL. The contact hole CNT may penetrate the first insulating layer 10 to the sixth insulating layer 60 (see reference). Figure 5a Part of it, and through the first input insulating layer ISL-IL1 of the input sensor ISL (refer to) Figure 6 ) and the second input insulating layer ISL-IL2 (refer to Figure 6 ).

[0136] Each of the first sensing electrodes IE1-1 to IE1-10 may include a plurality of first sensor units SP1 and a plurality of first connecting units CP1. Each of the second sensing electrodes IE2-1 to IE2-8 includes a plurality of second sensor units SP2 and a plurality of second connecting units CP2.

[0137] Each of the first connecting lines CNL1-1 to CNL1-5 is electrically connected to two corresponding first sensing electrodes IE1-1 to IE1-10 (hereinafter referred to as "first sensing electrode pairs"). For example, first connecting line CNL1-1 is electrically connected to first sensing electrodes IE1-1 and IE1-2, and first connecting line CNL1-2 is electrically connected to first sensing electrodes IE1-3 and IE1-4. Figure 7a In the example shown, the first connecting lines CNL1-1 to CNL1-5 are electrically connected to adjacent pairs of first sensing electrodes IE1-1 to IE1-10; however, the present invention is not limited thereto. For example, the first connecting line CNL1-1 can be electrically connected to first sensing electrodes IE1-1 and IE1-3 that are not adjacent to each other.

[0138] Each of the first connecting lines CNL1-1 to CNL1-5 can be connected to the other end of the first sensing electrodes IE1-1 to IE1-10 that is not connected to the first sensing lines SL1-1 to SL1-10. The first sensing lines SL1-1 to SL1-10 can be formed in the same layer using the same material as the first sensor part SP1.

[0139] Each of the second connecting lines CNL2-1 to CNL2-4 is electrically connected to two corresponding second sensing electrodes IE2-1 to IE2-8 (hereinafter referred to as "second sensing electrode pairs"). For example, second connecting line CNL2-1 is electrically connected to second sensing electrodes IE2-1 and IE2-2, and second connecting line CNL2-2 is electrically connected to second sensing electrodes IE2-3 and IE2-4. Figure 7a In the example shown, the second connecting lines CNL2-1 to CNL2-4 are electrically connected to adjacent pairs of second sensing electrodes IE2-1 to IE2-8. However, the present invention is not limited thereto. For example, the second connecting line CNL2-1 can be electrically connected to second sensing electrodes IE2-1 and IE2-3 that are not adjacent to each other.

[0140] Each of the second connecting lines CNL2-1 to CNL2-4 can be connected to the other end of the two ends of the second sensing electrodes IE2-1 to IE2-8 that is not connected to the second sensing lines SL2-1 to SL2-8. The second sensing lines SL2-1 to SL2-8 can be formed on the same layer using the same material as the second sensor part SP2.

[0141] Figure 7c The diagram illustrates the relationship between... Figure 7b The section corresponding to I-I'. Figure 7cThe figure illustrates an embodiment where the first connecting portion CP1 and the second connecting portion CP2 intersect. In this embodiment, the first connecting portion CP1 can be equivalent to a bridge pattern. In another embodiment of the invention, the second connecting portion CP2 can also be a bridge pattern.

[0142] Reference Figure 7b and Figure 7c Multiple first connection portions CP1 can be connected from the first conductive layer ISL-CL1 (refer to...) Figure 6 Multiple first sensor units SP1, multiple second sensor units SP2, and multiple second connection units CP2 are formed from the second conductive layer ISL-CL2. The first sensor units SP1 and the first connection units CP1 can be connected through contact holes CNT-IL2 that penetrate the second input insulating layer ISL-IL2.

[0143] This embodiment illustrates a scenario where multiple first connecting portions CP1 and multiple second connecting portions CP2 intersect, but it is not limited to this. For example, each of the first connecting portions CP1 can be deformed into a curve "∧" and / or a curve "∨" shape, so as not to overlap with the second connecting portions CP2. The first connecting portion CP1 in the shape of a curve "∧" and / or a curve "∨" can overlap with the second sensor portion SP2 on a plane.

[0144] According to the present invention, the first sensing lines SL1-1 to SL1-10 and the second sensing lines SL2-1 to SL2-8 include at least one of the portions arranged on the same layer as the first sensing electrodes IE1-1 to IE1-10 and the portions arranged on the same layer as the second sensing electrodes IE2-1 to IE2-8.

[0145] Figure 7d The diagram illustrates the relationship between... Figure 7a The cross section corresponding to II-II' is illustrated. First sensing lines SL1-9 to SL1-10 of the first sensing lines SL1-1 to SL1-10 are exemplary. The first sensing lines SL1-1 to SL1-10 at least include portions disposed on the same layer as the first sensing electrodes IE1-1 to IE1-10. The first sensing lines SL1-1 to SL1-10 and the second sensing lines SL2-1 to SL2-8 may also include portions from the first conductive layer ISL-CL1 (refer to...). Figure 6 The part formed.

[0146] Refer again Figure 7a In sensing the user's first input TC1 (refer to) Figure 1During the first sensing mode, the first sensing electrodes IE1-1 to IE1-10 and the second sensing electrodes IE2-1 to IE2-8 sense the user's first input TC1 and output the sensing signal to at least one of the first sensing lines SL1-1 to SL1-10 and the second sensing lines SL2-1 to SL2-8.

[0147] The second input TC2 of the sensing pen EP (refer to) Figure 1 During the second sensing mode, the first sensing electrode pair and the second sensing electrode pair sense the second input TC2 and output to at least one of the first sensing lines SL1-1 to SL1-10 and the second sensing lines SL2-1 to SL2-8. During the second sensing mode, for example, a loop formed by the first sensing line SL1-1, the first sensing electrode IE1-1, the first connecting line CNL1-1, the first sensing electrode IE1-2, and the first sensing line SL1-2 can resonate with a capacitor (not shown) inside the electronic pen EP to emit electromagnetic force or receive touch information.

[0148] like Figure 7a As shown, besides the first input TC1 used to sense the user (refer to...), Figure 1 In addition to the first sensing electrodes IE1-1 to IE1-10 and the second sensing electrodes IE2-1 to IE2-8, the input sensor ISL may also include only the first connecting lines CNL1-1 to CNL1-5 and the second connecting lines CNL2-1 to CNL2-4 to sense the second input TC2 of the electronic pen EP (see reference). Figure 1 Therefore, an input sensor ISL and a display device DD can be provided that can sense the user's first input TC1 and the electronic pen EP's second input TC2 while minimizing the increase in production costs. Figure 2 (As shown).

[0149] Figure 7e This is a simplified illustration to illustrate the second sensing mode of the second input of the sensing pen. Figure 7a The diagram shows the first sensing electrodes IE1-1 to IE1-10 and the second sensing electrodes IE2-1 to IE2-8 of the input sensor ISL.

[0150] Reference Figure 7a and Figure 7e At least one of the first sensing electrodes IE1-1 to IE1-10 and the second sensing electrodes IE2-1 to IE2-8 can operate as a drive coil that senses magnetic field lines due to the flow of current, and the other can operate as a sensing coil that senses voltage through magnetic field lines.

[0151] For example, the first coils C1-1 to C1-5 formed by the first sensing lines SL1-1 to SL1-10 and the first sensing electrodes IE1-1 to IE1-10 can be operated as drive coils. Furthermore, the second coils C2-1 to C2-4 formed by the second sensing lines SL2-1 to SL2-8 and the second sensing electrodes IE2-1 to IE2-8 can be operated as sensing coils.

[0152] Each of the first coils C1-1 to C1-5 is fed from the second sensing circuit EP-C (refer to...). Figure 4 The current path receives current and forms a closed loop. If the electronic pen EP (refer to...) Figure 1 When a coil approaches one of the first coils C1-1 to C1-5, it resonates with a capacitor (not shown) inside the electronic pen EP, creating a magnetic field around the current path. At this time, a current flows through one of the second coils C2-1 to C2-4 due to the magnetic field. Therefore, by sensing the signal changes received from the second sensing lines SL2-1 to SL2-8, the second input TC2 generated by the electronic pen EP can be sensed.

[0153] For example, suppose a second input TC2 is input at a predetermined position (x, y). When current flows through the first coil C1-4, which is adjacent to the predetermined position (x, y), the first coil C1-4 can resonate with a capacitor (not shown) inside the electronic pen EP, thereby forming a magnetic field. At this time, current flows through the second coil C2-3, which is orthogonal to the first coil C1-4 and adjacent to the predetermined position (x, y). The second sensing circuit EP-C can sense the current changes in the second sensing lines SL2-5 and SL2-6 when current is supplied to the first sensing lines SL1-7 and SL1-8, thereby detecting the input position (x, y) of the second input TC2.

Figure 8b It is shown in magnification Figure 8a The diagram shows the second region BB of the input sensor ISL2.

The input sensor ISL2 may include a sensing area ISL-DA and a wiring area ISL-NDA corresponding to the display area DP-DA and non-display area DP-NDA of the display panel DP. The sensing area ISL-DA can be defined as the area where the first sensing electrodes IE1-1 to IE1-10 and the second sensing electrodes IE2-1 to IE2-8 are arranged. The first sensing lines SL1-1 to SL1-10, the second sensing lines SL2-1 to SL2-8, the third sensing lines SL3-1 to SL3-10, and the fourth sensing lines SL4-1 to SL4-8 ​​are arranged in the wiring area ISL-NDA.

[0156] Each of the first sensing electrodes IE1-1 to IE1-10 has a shape extending along the second direction DR2. Furthermore, the first sensing electrodes IE1-1 to IE1-10 can be arranged sequentially along the first direction DR1. Each of the second sensing electrodes IE2-1 to IE2-8 has a shape extending along the first direction DR1. Furthermore, the second sensing electrodes IE2-1 to IE2-8 can be arranged sequentially along the second direction DR2.

[0157] The first sensing lines SL1-1 to SL1-10 may include the same number of signal lines as the first sensing electrodes IE1-1 to IE1-10. The first sensing lines SL1-1 to SL1-10 may be connected to at least one of the two ends of the first sensing electrodes IE1-1 to IE1-10.

Figure 6 A plurality of first sensor units SP1, a plurality of second sensor units SP2, and a plurality of second connecting units CP2 are formed from a second conductive layer ISL-CL2. The first sensor units SP1 and the first connecting units CP1 can be connected through contact holes SCNT3 penetrating the second input insulating layer ISL-IL2. This embodiment illustrates a case where the plurality of first connecting units CP1 and the plurality of second connecting units CP2 intersect each other; however, it is not limited to this. For example, each of the first connecting units CP1 can be deformed into a curve “∧” and / or a curve “∨” shape, so as not to overlap with the second connecting units CP2. The first connecting units CP1 in the shape of curves “∧” and / or curves “∨” can overlap with the second sensor units SP2 on a plane.

[0168] like Figure 8c As shown, the first sub-sensor unit SSP1 and the first sub-connector unit SCP1 can be connected through the first sub-contact hole SCNT1 penetrating the second input insulating layer ISL-IL2. The second sub-sensor unit SSP2 and the first sub-connector unit SCP1 can be connected through the second sub-contact hole SCNT2 penetrating the second input insulating layer ISL-IL2. Furthermore, the first sub-sensor unit SSP1 and the first connecting part CP1 can be connected through the third sub-contact hole SCNT3 penetrating the second input insulating layer ISL-IL2. Thus, the first sub-sensor unit SSP1 and the second sub-sensor unit SSP2 can be electrically connected through the first sub-connector unit SCP1 and the first connecting part CP1. Furthermore, the first sub-sensor unit SSP1 and the fourth sensing lines SL4-1 to SL4-8 ​​can be insulated from each other through the second input insulating layer ISL-IL2.

[0169] like Figure 8dAs shown, the third sub-sensor unit SSP3 and the second sub-connector unit SCP2 can be connected via the fourth sub-contact hole SCNT4 penetrating the second input insulating layer ISL-IL2. Furthermore, the fourth sub-sensor unit SSP4 and the second sub-connector unit SCP2 can be connected via the fifth sub-contact hole SCNT5 penetrating the second input insulating layer ISL-IL2. Thus, the third sub-sensor unit SSP3 and the fourth sub-sensor unit SSP4 are electrically connected via the second sub-connector unit SCP2. Furthermore, the third sub-sensor unit SSP3 and the fourth sub-sensor unit SSP4 are insulated from each other via the second input insulating layer ISL-IL2.

[0170] like Figure 8e As shown, the fourth sensing line SL4-1 and the third sub-connector SCP3 can be connected via the sixth sub-contact hole SCNT6 penetrating the second input insulating layer ISL-IL2. Furthermore, the third sub-connector SCP3 and the fourth sensing line SL4-1 can be connected via the seventh sub-contact hole SCNT7 penetrating the second input insulating layer ISL-IL2. Thus, the fourth sensing line SL4-1 can be electrically connected via the third sub-connector SCP3. Moreover, the third sensing lines SL3-1 to SL3-10 and the fourth sensing lines SL4-1 to SL4-8 ​​can be insulated from each other via the second input insulating layer ISL-IL2.

[0172] Refer again Figure 8a In sensing the user's first input TC1 (refer to) Figure 1 During the first sensing mode, the first sensing electrodes IE1-1 to IE1-10 and the second sensing electrodes IE2-1 to IE2-8 sense the user's first input TC1 and output the sensing signal to at least one of the first sensing lines SL1-1 to SL1-10 and the second sensing lines SL2-1 to SL2-8.

[0173] The second input TC2 of the sensing pen EP (refer to) Figure 1During the second sensing mode, the third sensing line pairs of the third sensing lines SL3-1 to SL3-10 and the fourth sensing line pairs of the fourth sensing lines SL4-1 to SL4-8 ​​sense the second input TC2 and output it to at least one of the third sensing lines SL3-1 to SL3-10 and the fourth sensing lines SL4-1 to SL4-8. During the second sensing mode, for example, a loop formed by a pair of third sensing lines SL3-1 and SL3-2 can resonate with a capacitor (not shown) inside the electronic pen EP to emit electromagnetic force or receive touch information.

[0174] like Figure 8a As shown, besides the first input TC1 used to sense the user (refer to...), Figure 1 In addition to the first sensing electrodes IE1-1 to IE1-10 and the second sensing electrodes IE2-1 to IE2-8, the input sensor ISL2 may also include the third sensing lines SL3-1 to SL3-10 and the fourth sensing lines SL4-1 to SL4-8 ​​to sense the second input TC2 of the electronic pen EP (see reference). Figure 1 In particular, the third sensing lines SL3-1 to SL3-10 and the fourth sensing lines SL4-1 to SL4-8 ​​can be formed from the same first conductive layer ISL-CL1 and second conductive layer ISL-CL2 as the first sensing electrodes IE1-1 to IE1-10 and the second sensing electrodes IE2-1 to IE2-8. Therefore, an input sensor ISL2 and a display device DD can be provided that can sense the user's first input TC1 and the electronic pen EP's second input TC2 while minimizing the increase in production costs. Figure 2 (As shown).

[0175] Since the third sensing lines SL3-1 to SL3-10 are respectively arranged between the third sub-sensor section SSP3 and the fourth sub-sensor section SSP4 of the second sensor section SP2, they do not overlap with the second connecting portion CP2 of the second sensor section SP2. Therefore, short-circuit defects caused by the overlap of the third sensing lines SL3-1 to SL3-10 with the second connecting portion CP2 can be prevented. Furthermore, since the third sensing lines SL3-1 to SL3-10 are respectively arranged between the third sub-sensor section SSP3 and the fourth sub-sensor section SSP4 of the second sensor section SP2, the effects of signal interference or electrostatic discharge (ESD) between the third sub-sensor section SSP3 and the fourth sub-sensor section SSP4 and the third sensing lines SL3-1 to SL3-10 can be minimized.

[0176] Since the fourth sensing lines SL4-1 to SL4-8 ​​are respectively arranged between the first sub-sensor section SSP1 and the second sub-sensor section SSP2 of the first sensor section SP1, they do not overlap with the first connecting portion CP1 of the first sensor section SP1. Therefore, short-circuit defects caused by the overlap of the fourth sensing lines SL4-1 to SL4-8 ​​with the first connecting portion CP1 can be prevented. Furthermore, since the fourth sensing lines SL4-1 to SL4-8 ​​are respectively arranged between the first sub-sensor section SSP1 and the second sub-sensor section SSP2 of the first sensor section SP1, the effects of signal interference or electrostatic discharge (ESD) between the first sub-sensor section SSP1 and the second sub-sensor section SSP2 of the first sensor section SP1 and the fourth sensing lines SL4-1 to SL4-8 ​​can be minimized.

One end of each of the third sensing lines SL3-1 to SL3-10 is connected to the other end of the corresponding first sensing electrode among the first sensing electrodes IE1-1 to IE1-10.

Figure 6 A plurality of first sensor units SP1, a plurality of second sensor units SP2, and a plurality of second connecting units CP2 are formed from the second conductive layer ISL-CL2. The first sensor units SP1 and the first connecting units CP1 can be connected through contact holes SCNT13 penetrating the second input insulating layer ISL-IL2. This embodiment illustrates a case where the plurality of first connecting units CP1 and the plurality of second connecting units CP2 intersect each other; however, it is not limited to this. For example, each of the first connecting units CP1 can be deformed into a curve “∧” and / or a curve “∨” shape, so as not to overlap with the second connecting units CP2. The first connecting units CP1 in the shape of curves “∧” and / or curves “∨” can overlap with the second sensor units SP2 on a plane.

[0191] like Figure 9c As shown, the first sub-sensor unit SSP1 and the first sub-connector unit SCP1 can be connected through the first sub-contact hole SCNT11 penetrating the second input insulating layer ISL-IL2.

The first sub-sensor unit SSP1 and the first connecting part CP1 can be connected through the third sub-contact hole SCNT13 penetrating the second input insulating layer ISL-IL2. Thus, the first sub-sensor unit SSP1 and the second sub-sensor unit SSP2 can be electrically connected through the first sub-connector unit SCP1 and the first connecting part CP1. Furthermore, the first sub-sensor unit SSP1 and the fourth sensing lines SL4-1 to SL4-8 ​​can be insulated from each other through the second input insulating layer ISL-IL2.

Furthermore, the fourth sub-sensor unit SSP4 and the second sub-connector unit SCP2 can be connected via the fifth sub-contact hole SCNT15 penetrating the second input insulating layer ISL-IL2.

Furthermore, the second sub-sensor SSP2 and the fourth sub-connector SCP4 can be connected via the seventh sub-contact hole SCNT17 penetrating the second input insulating layer ISL-IL2. Thus, the third sensing lines SL3-2 to SL3-9 can be electrically connected to the second sub-sensor SSP2 via the fourth sub-connector SCP4. Additionally, two adjacent third sensing lines among the third sensing lines SL3-1 to SL3-10 (e.g., SL3-9 and SL3-10) can be insulated from each other via the second input insulating layer ISL-IL2.

[0195] exist Figure 9a In this case, a portion of the first sensing lines SL1-1 to SL1-10 and a portion of the third sensing lines SL3-1 to SL3-10 may cross in the wiring area ISL-NDA. In this situation, as... Figure 9e As shown, one of the first sensing lines SL1-1 to SL1-10 and the third sensing lines SL3-1 to SL3-10 can be connected in a bridge pattern via sub-connectors. Furthermore, the first sensing lines SL1-1 to SL1-10 and the third sensing lines SL3-1 to SL3-10 can be insulated from each other via the second input insulating layer ISL-IL2. (Refer to again...) Figure 9a In sensing the user's first input TC1 (refer to) Figure 1 During the first sensing mode, the first sensing electrodes IE1-1 to IE1-10 and the second sensing electrodes IE2-1 to IE2-8 sense the user's first input TC1 and output the sensing signal to at least one of the first sensing lines SL1-1 to SL1-10 and the second sensing lines SL2-1 to SL2-8.

Therefore, an input sensor ISL3 and a display device DD can be provided that can sense the user's first input TC1 and the electronic pen EP's second input TC2 while minimizing the increase in production costs. Figure 2 (As shown).

[0199] Since the third sensing lines SL3-1 to SL3-10 are respectively arranged between the third sub-sensor section SSP3 and the fourth sub-sensor section SSP4 of the second sensor section SP2, they do not overlap with the second connecting portion CP2 of the second sensor section SP2. Therefore, short-circuit defects caused by the overlap of the third sensing lines SL3-1 to SL3-10 with the second connecting portion CP2 can be prevented. Furthermore, since the third sensing lines SL3-1 to SL3-10 are respectively arranged between the third sub-sensor section SSP3 and the fourth sub-sensor section SSP4 of the second sensor section SP2, the effects of signal interference or electrostatic discharge (ESD) between the third sub-sensor section SSP3 and the fourth sub-sensor section SSP4 and the third sensing lines SL3-1 to SL3-10 can be minimized.

[0200] Since the fourth sensing lines SL4-1 to SL4-8 ​​are respectively arranged between the first sub-sensor section SSP1 and the second sub-sensor section SSP2 of the first sensor section SP1, they do not overlap with the first connecting portion CP1 of the first sensor section SP1. Therefore, short-circuit defects caused by the overlap of the fourth sensing lines SL4-1 to SL4-8 ​​with the first connecting portion CP1 can be prevented. Furthermore, since the fourth sensing lines SL4-1 to SL4-8 ​​are respectively arranged between the first sub-sensor section SSP1 and the second sub-sensor section SSP2 of the first sensor section SP1, the effects of signal interference or electrostatic discharge (ESD) between the first sub-sensor section SSP1 and the second sub-sensor section SSP2 of the first sensor section SP1 and the fourth sensing lines SL4-1 to SL4-8 ​​can be minimized.

[0201] and, Figure 9a The input sensor ISL3 shown uses first sensing electrodes IE1-1 to IE1-10 and second sensing electrodes IE2-1 to IE2-8 as part of the signal path for sensing the second input TC2.
