Description

[0001] This application claims priority to and the benefit of Korean Patent Application No. 10-2019-0109502, filed on September 4, 2019, and No. 10-2019-0139935, filed on November 5, 2019, which are hereby incorporated by reference for all purposes as if fully set forth herein. Technical Field

[0002] Exemplary embodiments of the invention relate to a touch sensing unit and a display device including the touch sensing unit. Background Art

[0003] Display devices for displaying images are used in various electronic appliances such as smartphones, tablet PCs, digital cameras, notebook computers, navigation systems, and televisions to provide images to users. Display devices include a display panel for generating and displaying images and various input devices.

[0004] Recently, in the fields of smartphones and tablet PCs, touch sensing units that recognize touch inputs have been widely used in display devices. The touch sensing units determine whether a user inputs a touch and calculate a corresponding position as touch input coordinates.

[0005] The touch sensing unit includes first touch electrodes electrically connected in a first direction and second touch electrodes electrically connected in a second direction intersecting the first direction.

[0006] As the bezel area of ​​display devices decreases and the edges of the display screen adopt a rounded (or chamfered) shape (corner-rounded shape), the edges of the touch sensing unit corresponding to the edges of the display screen may also adopt a rounded shape (corner-rounded shape). However, when this corner-rounded shape is applied, the area of ​​the first and second touch electrodes at the bottom edge of the touch sensing unit may decrease more than the area of ​​the first and second touch electrodes at the top edge of the touch sensing unit. In this case, due to the reduction in sensing area at the bottom edge of the touch sensing unit, the charging rate may decrease, which may lead to a decrease in touch detection power.

[0007] The above information disclosed in this Background section is only for understanding the background of the inventive concept and therefore it may contain information that does not constitute the prior art. Summary of the Invention

[0067] In the following description, for the purpose of explanation, many specific details are set forth to provide a thorough understanding of the various exemplary embodiments of the invention. As used herein, an "embodiment" is a non-limiting example of a device or method that adopts one or more of the inventive concepts disclosed herein. However, it is apparent that the various exemplary embodiments can be practiced without these specific details or with one or more equivalent arrangements. In other cases, well-known structures and devices are shown in block diagram form to avoid making the various exemplary embodiments unnecessarily obscure. In addition, the various exemplary embodiments may be different, but are not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, configuration (configuration) and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0068] Unless otherwise specified, the exemplary embodiments shown are to be understood as providing exemplary features of varying details of some of the ways in which the inventive concept can be implemented in practice. Therefore, unless otherwise specified, the features, components, modules, layers, films, panels, regions and / or aspects, etc. (hereinafter, individually or collectively referred to as "elements") of the various embodiments may be further combined, separated, interchanged and / or rearranged without departing from the inventive concept.

[0069] The use of cross hatching and / or shading is generally provided in the accompanying drawings to make the boundaries between adjacent elements clear. Thus, unless otherwise specified, the presence and absence of cross hatching or shading do not convey or represent any preference or requirement for the specific material, material properties, size, ratio, commonality between the elements shown and / or any other characteristics, attributes, properties, etc. of the elements. In addition, in the accompanying drawings, the size and relative size of the elements can be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two processes described in succession can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same reference numerals represent the same elements.

[0070] When an element or layer is referred to as being "on," "connected to," or "coupled to" another element or layer, the element or layer may be directly on, directly connected to, or directly coupled to the other element or layer, or there may be intervening elements or layers. However, when an element or layer is referred to as being "directly on," "directly connected to," or "directly coupled to" another element or layer, there are no intervening elements or layers. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, and / or a fluid connection with or without intervening elements. In addition, the D1 axis, the D2 axis, and the D3 axis are not limited to the three axes of a rectangular coordinate system (such as the x-axis, the y-axis, and the z-axis), but may be interpreted in a broader sense. For example, the D1 axis, the D2 axis, and the D3 axis may be perpendicular to each other, or may 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” may 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 for example. As used herein, the term “and / or” includes any and all combinations of one or more of the relevant listed items.

[0071] Although the terms "first," "second," etc. may be used herein 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. Thus, the first element discussed below could be named the second element without departing from the disclosed teachings.

[0072] In this specification, "on," "above," "top," "upper side," or "upper surface" refers to the direction along which the touch sensing unit TDU is disposed relative to the display panel 100 (i.e., the Z-axis direction), and "under," "below," "bottom," "lower side," or "lower surface" refers to the direction along which the display panel 100 is disposed relative to the touch sensing unit TDU (i.e., the direction opposite to the Z-axis direction). Furthermore, "left," "right," "upper," and "lower" refer to directions when the display panel 100 is viewed from a planar perspective. For example, "left" refers to the direction opposite to the X-axis direction, "right" refers to the X-axis direction, "upper" refers to the Y-axis direction, and "lower" refers to the direction opposite to the Y-axis direction.

[0073] Furthermore, the device may be otherwise oriented (eg, rotated 90 degrees or at other orientations) and, as such, the spatially relative descriptors used herein interpreted accordingly.

[0074] The terms used herein are for the purpose of describing specific embodiments and are not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms "a", "one", and "said" are also intended to include plural forms. In addition, when the terms "comprise" and variations thereof and / or "include" and variations thereof are used in this specification, the description indicates the presence of the stated features, integral bodies, steps, operations, elements, components, and / or groups thereof, but do not exclude the presence or addition of one or more other features, integral bodies, steps, operations, elements, components, and / or groups thereof. It is also noted that, as used herein, the terms "substantially", "approximately", and other similar terms are used as approximate terms rather than as terms of degree, and as such, they are used to explain the inherent deviations of measured values, calculated values, and / or provided values ​​that will be recognized by those of ordinary skill in the art.

[0075] Various exemplary embodiments are described herein with reference to cross-sectional views and / or exploded views that are schematic diagrams of idealized exemplary embodiments and / or intermediate structures. As such, variations in the shapes of the illustrations due to, for example, manufacturing techniques and / or tolerances are anticipated. Therefore, the exemplary embodiments disclosed herein should not necessarily be construed as limited to the shapes of the specifically illustrated regions, but rather are intended to include deviations in shape due to, for example, manufacturing. In this manner, the regions illustrated in the accompanying drawings may be schematic in nature, and the shapes of these regions may not reflect the actual shapes of regions of the device and, as such, are not necessarily intended to be limiting.

[0076] Unless otherwise defined, all terms used herein (including technical and scientific terms) 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 commonly used dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and should not be interpreted in an idealized or overly formal sense unless expressly defined as such herein.

[0077] Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

[0078] Figure 1 is a perspective view of a display device according to an exemplary embodiment, Figure 2 is a plan view of a display device according to an exemplary embodiment.

[0079] Reference Figure 1 and Figure 2The display device 10 is a device for displaying moving or still images. The display device 10 can be used as a display screen for various products (such as televisions, notebooks, monitors, billboards, and the Internet of Things) and portable electronic appliances (such as mobile phones, smartphones, tablet personal computers (PCs), smart watches, watch phones, mobile communication terminals, electronic notebooks, e-books, portable multimedia players (PMPs), navigation systems, and ultra-mobile PCs (UMPs)). The display device 10 can be any of an organic light-emitting display device, a liquid crystal display device, a plasma display device, a field emission display device, an electrophoretic display device, an electrowetting display device, a quantum dot emission display device, and a micro-LED display device. Hereinafter, the display device 10 will be described assuming that it is an organic light-emitting display device, but the inventive concept is not limited thereto.

[0080] The display device 10 according to an exemplary embodiment may include a display panel 100 , a display driving circuit 200 , a display circuit board 300 , a touch driving circuit 400 , a touch circuit board 410 , and a touch sensing unit TDU.

[0081] The display panel 100 may have a rectangular planar shape having a short side in a first direction (X-axis direction) and a long side in a second direction (Y-axis direction) intersecting the first direction (X-axis direction). The corner where the short side in the first direction (X-axis direction) meets the long side in the second direction (Y-axis direction) may be rounded with a predetermined curvature or have a right angle. The planar shape of the display panel 100 is not limited to a rectangular shape and may be another polygonal shape, a circular shape, or an elliptical shape.

[0082] The display panel 100 may be formed to be flat, but the inventive concept is not limited thereto. The display panel 100 may include curved portions formed at its left and right ends. In this case, the curved portions may have a constant curvature or a variable curvature. In addition, the display panel 100 may be formed to be flexible so that the display panel 100 is bent, folded, or curled.

[0083] The display panel 100 may include pixels disposed in a display area to display an image and display electrode pads ("pads," also referred to as "pads" or "pads") disposed in a non-display area surrounding the display area. The display electrode pads may be formed on one edge of the display panel 100 to be electrically connected to the display circuit board 300. Figure 3 and Figure 5 Details of the display panel 100 are described.

[0084] The display driver circuit 200 outputs signals and voltages for driving the display panel 100. For example, the display driver circuit 200 can supply data voltages to data lines. Furthermore, the display driver circuit 200 can supply power voltages to power lines and scan control signals to a scan driver. The display driver circuit 200 can be formed as an integrated circuit (IC) and can be attached to the display panel 100 using a chip-on-glass (COG) method, a chip-on-plastic (COP) method, or an ultrasonic bonding method. The display driver circuit 200 can be attached to the display panel 100 that is exposed and not covered by the touch sensing unit TDU. Alternatively, the display driver circuit 200 can be mounted on the display circuit board 300.

[0085] The display circuit board 300 may be attached to the display electrode pads of the display panel 100 using an anisotropic conductive film. Thus, the leads of the display circuit board 300 may be electrically connected to the display electrode pads of the display panel 100. The display circuit board 300 may be a flexible printed circuit board, a printed circuit board, or a flexible film such as a chip on film.

[0086] The touch sensing unit TDU may be provided on the display panel 100. The touch sensing unit TDU may have a rectangular planar shape having a short side in a first direction (X-axis direction) and a long side in a second direction (Y-axis direction). The corner where the short side in the first direction (X-axis direction) meets the long side in the second direction (Y-axis direction) may be rounded with a predetermined curvature or have a right angle. The planar shape of the touch sensing unit TDU is not limited to a rectangular shape and may be another polygonal shape, a circular shape, or an elliptical shape. The planar shape of the touch sensing unit TDU may be similar to the planar shape of the display panel 100.

[0087] The touch sensing unit TDU may include curved portions formed at its left and right ends. In this case, the curved portions may have a constant or variable curvature. The curved portion located above the touch sensing unit TDU in the second direction (Y-axis direction) may have a smaller radius of curvature than the curved portion located below the touch sensing unit TDU in the second direction (Y-axis direction). Because the curved portion located above the touch sensing unit TDU in the second direction (Y-axis direction) has a different radius of curvature than the curved portion located below the touch sensing unit TDU in the second direction (Y-axis direction), as will be described later, a touch electrode adjacent to the curved portion located above the touch sensing unit TDU in the second direction (Y-axis direction) may have an area different from that of a touch electrode adjacent to the curved portion located below the touch sensing unit TDU in the second direction (Y-axis direction).

[0088] In addition, like the display panel 100 , the touch sensing unit TDU may be formed to be flexible such that the touch sensing unit TDU may be bent, curved, folded, or rolled.

[0089] The touch sensing unit TDU may include touch electrodes disposed in the touch sensor region to detect a user's touch and touch electrode pads disposed in a touch peripheral region surrounding the touch sensor region. The touch electrode pads may be formed on the touch sensing unit TDU at one edge thereof to electrically connect to the touch circuit board 410.

[0090] Will refer to it later Figure 3 and Figure 5 Describe the details of the touch sensing unit TDU. Figure 1 and Figure 2 2 shows that the touch sensing unit TDU is a separate touch panel separated from the display panel 100 , but the inventive concept is not limited thereto.

[0091] The touch circuit board 410 can be attached to the touch electrode pads of the touch sensing unit TDU using an anisotropic conductive film. Thus, the leads of the touch circuit board 410 can be electrically connected to the touch electrode pads of the touch sensing unit TDU. The touch circuit board 410 can be a flexible printed circuit board, a printed circuit board, or a flexible film such as a chip-on-film.

[0092] The touch drive circuit 400 can be connected to the touch electrodes of the touch sensing unit TDU. The touch drive circuit 400 applies a touch drive signal to the touch electrodes of the touch sensing unit TDU and measures the capacitance of the touch electrodes. The touch drive signal can include multiple drive pulses. The touch drive circuit 400 can not only determine whether a touch has been input based on the capacitance value but also calculate the touch coordinates of the input touch. The touch drive circuit 400 can be formed as an integrated circuit (IC) and can be mounted on the touch circuit board 410.

[0093] Figure 3 It is along Figure 2 An example of a cross-sectional view taken along line II'.

[0094] Reference Figure 3 , the display device 10 may include a display unit DU, a touch sensing unit TDU, and an adhesive member SEAL for attaching the display unit DU to the touch sensing unit TDU.

[0095] The display unit DU may include a first substrate SUB1, a thin film transistor layer TFTL, and a light emitting element layer EML.

[0096] The first substrate SUB1 can be a rigid substrate or a flexible substrate capable of bending, folding, curling, etc. The first substrate SUB1 may include an insulating material such as glass, quartz, or a polymer resin. Examples of polymer resins include polyethersulfone (PES), polyacrylate (PA), polyarylate (PAR), polyetherimide (PEI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polyallyl acrylate, polyimide (PI), polycarbonate (PC), cellulose triacetate (CAT), cellulose acetate propionate (CAP), and combinations thereof. Alternatively, the first substrate SUB1 may include a metal material.

[0097] The thin film transistor layer TFTL may be provided on the first substrate SUB1. The thin film transistor layer TFTL may be provided with not only a thin film transistor for each pixel, but also a scan line, a data line, a power line, a scan control line, and a data connection line for connecting the display driving circuit 200 and the data line. Each thin film transistor may include a gate electrode, a semiconductor layer, a source electrode, and a drain electrode. Figure 4 When the scan driver 110 is formed in the non-display area NDA of the display panel 100 as shown in FIG, the scan driver 110 may include a thin film transistor.

[0098] The thin film transistor layer TFTL may be disposed in the display area DA and the non-display area NDA. Specifically, the thin film transistor of each pixel of the thin film transistor layer TFTL, the scan line, the data line, and the power line may be disposed in the display area DA. In addition, the scan control line, the data connection line, and the pad connection line of the thin film transistor layer TFTL may be disposed in the non-display area NDA.

[0099] The light emitting element layer EML may be disposed on the thin film transistor layer TFTL. The light emitting element layer EML may include pixels and a pixel defining film defining the pixels, each pixel including a first electrode, a light emitting layer, and a second electrode. The pixels of the light emitting element layer EML may be disposed in the display area DA.

[0100] The light-emitting layer may be an organic light-emitting layer comprising an organic material. In this case, the light-emitting layer may include a hole transport layer, an organic light-emitting layer, and an electron transport layer. When a predetermined voltage is applied to the first electrode through the thin film transistor of the thin film transistor layer TFTL and a cathode voltage is applied to the second electrode, holes and electrons are transferred to the organic light-emitting layer through the hole transport layer and the electron transport layer, respectively, and combine with each other to emit light. In this case, the first electrode may be an anode electrode, and the second electrode may be a cathode electrode.

[0101] The touch sensing unit TDU may include a second substrate SUB2 and a touch sensor layer TSL.

[0102] The second substrate SUB2 can be a rigid substrate or a flexible substrate that can be bent, folded, curled, etc. The second substrate SUB2 may include an insulating material such as glass, quartz, or a polymer resin. Examples of polymer resins include polyethersulfone (PES), polyacrylate (PA), polyarylate (PAR), polyetherimide (PEI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polyallyl acrylate, polyimide (PI), polycarbonate (PC), cellulose triacetate (CAT), cellulose acetate propionate (CAP), and combinations thereof. Alternatively, the second substrate SUB2 may include a metal material. Furthermore, the second substrate SUB2 may serve as an encapsulation substrate for encapsulating the light-emitting element layer (EML).

[0103] The touch sensor layer TSL may be provided on the second substrate SUB2. The touch sensor layer TSL may include touch electrodes for capacitively sensing a user's touch, touch electrode pads, and touch signal lines for connecting the touch electrode pads and the touch electrodes. For example, the touch sensor layer TSL may sense a user's touch using a self-capacitance method or a mutual-capacitance method.

[0104] like Figure 5 and Figure 8 As shown in , the touch electrodes of the touch sensor layer TSL may be arranged in a touch sensor area TSA. That is, the touch sensor area TSA may be defined as a region in which the first touch electrode TE, the second touch electrode RE, the first-first touch electrode TEa, the second-first touch electrode REa, the connection electrode CE connecting the first touch electrode TE adjacent to the capacitance compensation patterns TEb and REb, and the first touch island electrode TEI are arranged.

[0105] The touch sensor area TSA may be aligned with the Figure 4 The touch sensor area TSA may not overlap with the non-display area NDA, but the inventive concept is not limited thereto. The touch sensor area TSA may partially overlap with the non-display area NDA.

[0106] The touch signal lines and the touch electrode pads of the touch sensor layer TSL may be disposed in a touch peripheral area TPA overlapping the non-display area NDA. The touch peripheral area TPA may be disposed around the touch sensor area TSA.

[0107] A polarizing film and a cover window may be additionally provided on the touch sensor layer TSL. In this case, the polarizing film may be provided on the touch sensor layer TSL, and the cover window may be attached to the polarizing film by a transparent adhesive member.

[0108] The adhesive member SEAL may attach the first substrate SUB1 of the display unit DU to the second substrate SUB2 of the touch sensing unit TDU. The adhesive member SEAL may be a frit adhesive layer, an ultraviolet curable resin layer, or a thermosetting resin layer, but is not limited thereto.

[0109] Despite Figure 3 FIG. 4 shows that the space between the light emitting element layer EML and the second substrate SUB2 is empty, but the inventive concept is not limited thereto. For example, a filling film may be provided between the light emitting element layer EML and the second substrate SUB2. The filling film may be an epoxy filling film or a silicone filling film.

[0110] Figure 4 It specifically shows Figure 3 For ease of explanation, Figure 4 Pixels P, scan lines SL, data lines DL, power lines PL, scan control lines SCL, a scan driver 110, a display driving circuit 200, display electrode pads DP, data link lines DLL, and pad link lines PLL of the display unit DU are shown.

[0111] Reference Figure 4 The display panel 100 may include a display area DA in which pixels P are formed to display an image and a non-display area NDA disposed around the display area DA. The non-display area NDA may be defined as a region from the outside of the display area DA to the edge of the display panel 100.

[0112] Scan lines SL, data lines DL, power lines PL, and pixels P may be arranged in the display area DA. The scan lines SL may extend in a first direction (X-axis direction), and the data lines DL may extend in a second direction (Y-axis direction) intersecting the first direction (X-axis direction). The power lines PL may include at least one line arranged parallel to the data lines DL in the second direction (Y-axis direction) and a plurality of lines branching from the at least one line in the first direction (X-axis direction).

[0113] Each pixel P can be connected to at least one scan line SL, at least one data line DL, and a power line PL. Each pixel P can include a thin film transistor, an organic light-emitting diode, and a capacitor. The thin film transistor includes a drive transistor and at least one switching transistor. When a scan signal is applied from the scan line SL, each pixel P can receive a data voltage from the data line DL and supply a drive current to the organic light-emitting diode in response to the data voltage applied to the gate electrode, thereby emitting light.

[0114] The scan driver 110 , the display driving circuit 200 , the scan control lines SCL, the data link lines DLL, and the pad link lines PLL may be disposed in the non-display area NDA.

[0115] The scan driver 110 is connected to the display driving circuit 200 through at least one scan control line SCL. Therefore, the scan driver 110 can receive a scan control signal from the display driving circuit 200. The scan driver 110 generates a scan signal according to the scan control signal and supplies the scan signal to the scan line SL.

[0116] Despite Figure 4 1 shows that the scan driver 110 is disposed in the non-display area NDA outside one side of the display area DA, but the inventive concept is not limited thereto. For example, the scan driver 110 may be disposed in the non-display area NDA outside both sides of the display area DA.

[0117] The display driver circuit 200 is connected to the display electrode pads DP of the display pad area DPA via pad connection lines PLL to receive digital video data and timing signals. The display driver circuit 200 converts the digital video data into analog positive / negative data voltages and supplies the analog positive / negative data voltages to the data lines DL via data connection lines DLL. Furthermore, the display driver circuit 200 generates scan control signals for controlling the scan driver 110 and supplies these scan control signals via scan control lines SCL. The scan signals from the scan driver 110 can select a pixel P to be supplied with a data voltage, and the data voltage can be supplied to the selected pixel P. The display driver circuit 200 can be formed as an integrated circuit (IC) and can be attached to the first substrate SUB1 using a chip-on-glass (COG) method, a chip-on-plastic (COP) method, or an ultrasonic bonding method.

[0118] Figure 5 It specifically shows Figure 3 A plan view of an example of a touch sensing unit.

[0119] Reference Figure 5 As described above, the touch sensing unit TDU may include curved portions formed at its left and right ends. The touch sensing unit TDU may include a first curved portion CR1 located at the upper left end in the second direction (Y direction), a second curved portion CR2 located at the upper right end in the second direction (Y direction), a third curved portion CR3 located at the lower left end in the second direction (Y direction), and a fourth curved portion CR4 located at the lower right end in the second direction (Y direction).

[0120] As described above, the curvature radius of the third curved portion CR3 and the curvature radius of the fourth curved portion CR4 may be larger than the curvature radius of the first curved portion CR1 and the curvature radius of the second curved portion CR2. That is, the line constituting the third curved portion CR3 and the line constituting the fourth curved portion CR4 may have a steeper line slope than the line constituting the first curved portion CR1 and the line constituting the second curved portion CR2.

[0121] The touch sensor area TSA of the touch sensing unit TDU may be an area surrounded by the first to fourth curved portions CR1 to CR4. Figure 8 As shown in , the touch sensor area TSA may include a first touch sensor area TSA1 located at the center of the touch sensing unit TDU and a second touch sensor area TSA2 located near the first touch sensor area TSA1. The center of the touch sensing unit TDU may be defined as a region in which the first touch electrode TE, the second touch electrode RE, a portion of the first-first touch electrode TEa adjacent to the second touch electrode RE, and a portion of the second-first touch electrode REa adjacent to the first touch electrode TE are arranged. The vicinity of the first touch sensor area TSA1 may be defined as a region in which another portion of the first-first touch electrode TEa spaced apart from the portion of the first-first touch electrode TEa adjacent to the second touch electrode RE, another portion of the second-first touch electrode REa spaced apart from the portion of the second-first touch electrode REa adjacent to the first touch electrode TE, and the capacitance compensation patterns TEb and REb are arranged. Therefore, the first touch sensor area TSA1 can be defined as an area in which the first touch electrode TE, the second touch electrode RE, a portion of the first-first touch electrode TEa adjacent to the second touch electrode RE, and a portion of the second-first touch electrode REa adjacent to the first touch electrode TE are arranged, and the second touch sensor area TSA2 can be defined as an area in which another portion of the first-first touch electrode TEa spaced apart from the portion of the first-first touch electrode TEa adjacent to the second touch electrode RE, another portion of the second-first touch electrode REa spaced apart from the portion of the second-first touch electrode REa adjacent to the first touch electrode TE, and the capacitance compensation patterns TEb and REb are arranged.

[0122] The touch sensing unit TDU may also include capacitance compensation patterns TEb and REb disposed adjacent to the third and fourth curved portions CR3 and CR4. The second touch sensor area TSA2 may be disposed so as to overlap the capacitance compensation patterns TEb and REb disposed adjacent to the third and fourth curved portions CR3 and CR4. In other words, the second touch sensor area TSA2 may be located to the lower left and lower right of the first touch sensor area TSA1 in the second direction (the Y direction).

[0123] The radius of curvature of the line formed by the boundary between the capacitance compensation patterns TEb and REb adjacent to the third curved portion CR3 and the first touch sensor area TSA1 can be substantially the same as the radius of curvature of the line formed by the boundary between the capacitance compensation patterns TEb and REb adjacent to the fourth curved portion CR4 and the first touch sensor area TSA1. The capacitance compensation patterns TEb and REb can include an opaque metal to function as a shielding film pattern for preventing light leakage in the second touch sensor area TSA2. Furthermore, as will be described later, a plurality of capacitance compensation patterns TEb and REb can be provided, and each of the plurality of capacitance compensation patterns TEb and REb can be electrically connected to the first-first touch electrode TEa and the second-first touch electrode REa located in the second touch sensor area TSA2 to increase the total capacitance in the second touch sensor area TSA2.

[0124] The first touch electrodes TE and the second touch electrodes RE may be arranged in the first touch sensor area TSA1. The first touch electrodes TE and the second touch electrodes RE may be spaced apart from each other. The first touch electrodes TE may be arranged in multiple columns in the second direction (Y-axis direction), and the second touch electrodes RE may be arranged in multiple rows in the first direction (X-axis direction). The first touch electrodes TE arranged in each of the multiple columns in the second direction (Y-axis direction) may be electrically connected to each other. Furthermore, the second touch electrodes RE arranged in each of the multiple rows in the first direction (X-axis direction) may be electrically connected to each other.

[0125] The first touch electrodes TE and the second touch electrodes RE provided in the first touch sensor area TSA1 may be formed roughly in a rhombus shape or a triangular shape on a plane. Specifically, the first touch electrodes TE and the second touch electrodes RE provided on the edge of the first touch sensor area TSA1 may be formed in a triangular shape on a plane, and the other first touch electrodes TE and the second touch electrodes RE may be formed in a rhombus shape on a plane.

[0126] In contrast, the areas of the first-first touch electrodes TEa and the second-first touch electrodes REa provided in the second touch sensor area TSA2 may be partially reduced along the bending line of the first to fourth bending portions CR1 to CR4 of the touch sensing unit TDU, thereby allowing the first-first touch electrodes TEa and the second-first touch electrodes REa to have an amorphous shape on a plane that is different from the aforementioned triangular shape. That is, the first-first touch electrodes TEa and the second-first touch electrodes REa may have a shape formed by cutting at least one vertex of the triangular shape along the bending line of the first to fourth bending portions CR1 to CR4 of the touch sensing unit TDU.

[0127] In addition, in order to prevent a moiré phenomenon from occurring by the first touch electrode TE and the first-first touch electrode TEa and the second touch electrode RE and the second-first touch electrode REa when viewing an image of the display device 10, the first touch electrode TE and the first-first touch electrode TEa and the second touch electrode RE and the second-first touch electrode REa may have protruding edges on a plane.

[0128] To prevent the first touch electrodes TE and first-first touch electrodes TEa from short-circuiting with the second touch electrodes RE and second-first touch electrodes REa at their intersections, the first touch electrodes TE and first-first touch electrodes TEa, which are adjacent to each other in the second direction (Y-axis direction), may be electrically connected via a connecting electrode CE. In this case, the first touch electrodes TE and first-first touch electrodes TEa, and the second touch electrodes RE and second-first touch electrodes REa may be arranged on a layer, while the connecting electrode CE may be arranged on a different layer from the first touch electrodes TE and first-first touch electrodes TEa, and the second touch electrodes RE and second-first touch electrodes REa. Consequently, the first touch electrodes TE and first-first touch electrodes TEa, which are electrically connected in the second direction (Y-axis direction), can be electrically insulated from the second touch electrodes RE and second-first touch electrodes REa, which are electrically connected in the first direction (X-axis direction).

[0129] First touch signal lines TL11 to TL1p (p is a positive integer of 2 or greater), second touch signal lines TL21 to TL2p (p is a positive integer of 2 or greater), third touch signal lines RL1 to RLq (q is a positive integer of 2 or greater), and touch electrode pads TP may be disposed in the touch peripheral area TPA.

[0130] One end of the first touch signal lines TL11 to TL1p may be connected to the first touch electrodes TE located on a first side of the touch sensor area TSA. The first side of the touch sensor area TSA may be the side closest to the touch pad area TDA where the touch electrode pads TP are located, among the four sides of the touch sensor area TSA. The other ends of the first touch signal lines TL11 to TL1p may be connected to some of the touch electrode pads TP in the touch pad area TDA. In other words, the first touch signal lines TL11 to TL1p may be used to connect the first touch electrodes TE located on the first side of the touch sensor area TSA to some of the touch electrode pads TP in the touch pad area TDA.

[0131] For example, Figure 5 As shown in , the first-first touch signal line TL11 can be electrically connected to the first touch electrode TE arranged in the first column of the touch sensor area TSA, and the first-second touch signal line TL12 can be electrically connected to the first touch electrode TE arranged in the second column of the touch sensor area TSA. In addition, the first-p-1th touch signal line TL1(p-1) can be electrically connected to the first touch electrode TE arranged in the p-1th column of the touch sensor area TSA, and the first-pth touch signal line TL1p can be electrically connected to the first touch electrode TE arranged in the p-th column of the touch sensor area TSA. In this case, the first column of the touch sensor area TSA can be the column arranged at the leftmost side of the touch sensor area TSA, and the p-th column can be the column arranged at the rightmost side of the touch sensor area TSA.

[0132] One end of the second touch signal line TL21 to TL2p may be connected to the first touch electrode TE disposed at the second side of the touch sensor area TSA. The second side of the touch sensor area TSA may be a side opposite to the first side, that is, forming a recessed area EA (see FIG. Figure 14 ). The other ends of the second touch signal lines TL21 to TL2p can be connected to other touch electrode pads TP of the touch pad area TDA. That is, the second touch signal lines TL21 to TL2p are used to connect the first touch electrodes TE disposed on the second side of the touch sensor area TSA to the other touch electrode pads TP of the touch pad area TDA.

[0133] For example, Figure 5As shown in , the second-first touch signal line TL21 can be electrically connected to the first touch electrode TE arranged in the first column of the touch sensor area TSA, and the second-second touch signal line TL22 can be electrically connected to the first touch electrode TE arranged in the second column of the touch sensor area TSA. In addition, the second-p-1th touch signal line TL2(p-1) can be electrically connected to the first touch electrode TE arranged in the p-1th column of the touch sensor area TSA, and the second-pth touch signal line TL2p can be electrically connected to the first touch electrode TE arranged in the p-th column of the touch sensor area TSA.

[0134] One end of each of the third touch signal lines RL1 to RLq can be connected to the second touch electrode RE located on the third side of the touch sensor area TSA. The third side of the touch sensor area TSA may be a side opposite to the fourth side of the touch sensor area TSA. The other ends of the third touch signal lines RL1 to RLq can be connected to other touch electrode pads TP of the touch pad area TDA. In other words, the third touch signal lines RL1 to RLq are used to connect the second touch electrode RE located on the third side of the touch sensor area TSA to the other touch electrode pads TP of the touch pad area TDA.

[0135] For example, Figure 5 As shown in , the third-first touch signal line RL1 can be electrically connected to the second touch electrode RE set in the first row of the touch sensor area TSA, the third-second touch signal line RL2 can be electrically connected to the second touch electrode RE set in the second row of the touch sensor area TSA, and the third-third touch signal line RL3 can be electrically connected to the second touch electrode RE set in the third row of the touch sensor area TSA. In addition, the third-q-3th touch signal line RLq-3 can be electrically connected to the second touch electrode RE set in the q-3th row of the touch sensor area TSA, the third-q-2th touch signal line RLq-2 can be electrically connected to the second touch electrode RE set in the q-2th row of the touch sensor area TSA, the third-q-1th touch signal line RLq-1 can be electrically connected to the second touch electrode RE set in the q-1th row of the touch sensor area TSA, and the third-qth touch signal line RLq can be electrically connected to the second touch electrode RE set in the qth row of the touch sensor area TSA.

[0136] The touch electrode pad TP may be provided at one side of the second substrate SUB2. The touch circuit board 410 may be attached to the touch electrode pad TP using an anisotropic conductive film. Therefore, the touch electrode pad TP may be electrically connected to the touch circuit board 410.

[0137] The first touch electrodes TE and the second touch electrodes RE may be driven by a mutual capacitance method or a self capacitance method.

[0138] First, when the first touch electrode TE and the second touch electrode RE are driven using a mutual capacitance method, a touch drive signal is supplied to the first touch electrode TE via the first touch signal lines TL11 to TL1p and the second touch signal lines TL21 to TL2p. As a result, the mutual capacitance formed at the intersection of the first touch electrode TE and the second touch electrode RE is charged. Then, the charge change in the mutual capacitance is measured by the second touch electrode RE, and whether a touch has been input is determined based on the charge change in the mutual capacitance. The touch drive signal may be a signal having multiple touch drive pulses.

[0139] Second, when the first touch electrodes TE and the second touch electrodes RE are driven using a self-capacitance method, a touch drive signal is supplied to both the first touch electrodes TE and the second touch electrodes RE through the first touch signal lines TL11 to TL1p, the second touch signal lines TL21 to TL2p, and the third touch signal lines RL1 to RLq. As a result, the self-capacitance of the first touch electrodes TE and the second touch electrodes RE is charged. Then, a charge change in the self-capacitance is measured through the first touch signal lines TL11 to TL1p, the second touch signal lines TL21 to TL2p, and the third touch signal lines RL1 to RLq, and whether a touch input has been made is determined based on the charge change in the self-capacitance.

[0140] Hereinafter, for ease of explanation, a description will be mainly given of a case where a plurality of touch drive pulses are applied to the first touch electrode TE and the first touch electrode TE and the second touch electrode RE are driven using a mutual capacitance method. In the mutual capacitance method, charge changes in mutual capacitance are measured via the third touch signal lines RL1 to RLq connected to the second touch electrode RE. In this case, the first touch electrode TE can serve as a touch drive electrode, the second touch electrode RE can serve as a touch sensing electrode, the first touch signal lines TL11 to TL1p and the second touch signal lines TL21 to TL2p can serve as touch drive lines, and the third touch signal lines RL1 to RLq can serve as touch sensing lines.

[0141] In addition, a first shield line GL1 , a second shield line GL2 , a third shield line GL3 , a fourth shield line GL4 , a first ground line GRL1 , and a second ground line GRL2 may be disposed in the touch peripheral area TPA.

[0142] The first guard line GL1 may be disposed outside the third to qth touch signal lines RLq, which are located at the outermost sides of the third touch signal lines RL1 to RLq. Furthermore, the first ground line GRL1 may be disposed outside the first guard line GL1. That is, because the first guard line GL1 is disposed between the third to qth touch signal lines RLq, which are located at the outermost sides of the third touch signal lines RL1 to RLq, and the first ground line GRL1, the first guard line GL1 may be used to minimize the effect of voltage variations of the first ground line GRL1 on the third to qth touch signal lines RLq. One end of the first guard line GL1 and one end of the first ground line GRL1 may be connected to the touch electrode pad TP located on the rightmost side.

[0143] The second guard line GL2 may be disposed between the third-first touch signal line RL1 and the first-pth touch signal line TL1p, which are disposed at the innermost side of the third touch signal lines RL1 to RLq. Thus, the second guard line GL2 may be used to minimize the influence of the third-first touch signal line RL1 and the first-pth touch signal line TL1p on each other. One end of the second guard line GL2 may be connected to the touch electrode pad TP.

[0144] The third protection line GL3 may be disposed between the second-first touch signal line TL21 and the first-first touch signal line TL11, which are located at the innermost sides of the second touch signal lines TL21 to TL2p. Thus, the third protection line GL3 may be used to minimize the mutual influence of the first-first touch signal line TL11 and the second-first touch signal line TL21. One end of the third protection line GL3 may be connected to the touch electrode pad TP.

[0145] The fourth guard line GL4 can be arranged outside the second-pth touch signal line TL2p, which is arranged at the outermost side of the second touch signal lines TL21 to TL2p. In addition, the second ground line GRL2 can be arranged outside the fourth guard line GL4. That is, because the fourth guard line GL4 is arranged between the second-pth touch signal line TL2p, which is arranged at the outermost side of the second touch signal lines TL21 to TL2p, and the second ground line GRL2, the fourth guard line GL4 can be used to minimize the impact of voltage changes of the second ground line GRL2 on the second-pth touch signal line TL2p. One end of the fourth guard line GL4 and one end of the second ground line GRL2 can be connected to the touch electrode pad TP located on the leftmost side.

[0146] The first ground line GRL1 may be provided at the outermost side from the right side of the touch sensing unit TDU, and the second ground line GRL2 may be provided at the outermost sides of the lower side, the left side, and the upper side of the touch sensing unit TDU, and a ground voltage may be applied to the first ground line GRL1 and the second ground line GRL2. Therefore, when static electricity is applied from the outside, the static electricity may be discharged to the first ground line GRL1 and the second ground line GRL2.

[0147] Meanwhile, when the first touch electrode TE and the second touch electrode RE are driven by the mutual capacitance method, preferably, the ground voltage is applied to the first to fourth shielding lines GL1 to GL2 , to the third to GL3 , and to the fourth shielding line GL4 .

[0148] Figure 6 It shows Figure 5 An enlarged plan view of an example of area A; Figure 7 It is along Figure 6 An example of a cross-sectional view taken along line II-II'; Figure 8 It shows Figure 5 An enlarged plan view of an example of region B; Figure 9 It is along Figure 8 An example of a cross-sectional view taken along line III-III'; Figure 10 It is along Figure 8 An example of a cross-sectional view taken along line IV-IV'; Figure 11 is a schematic diagram showing the capacitance Cm compensated in the second touch sensor area. Figure 8 , the touch electrode and the capacitance compensation pattern adjacent to the fourth curved portion CR4 will be described. However, the description of the touch electrode and the capacitance compensation pattern to be described later may also be applied to the third curved portion CR3.

[0149] Reference Figures 6 to 11 A thin film transistor layer TFTL is formed on the first substrate SUB1. The thin film transistor layer TFTL includes a thin film transistor 120, a gate insulating film 130, an interlayer insulating film 140, a protective film 150, and a planarization film 160.

[0150] A buffer film BF may be formed on one surface of the first substrate SUB1. The buffer film BF is formed on one surface of the first substrate SUB1 to protect the thin film transistor 120 and the organic light-emitting layer 172 of the light-emitting element layer EML from moisture that penetrates through the first substrate SUB1, which is susceptible to moisture permeation. The buffer film BF may be formed of a plurality of alternately stacked inorganic films. For example, the buffer film BF may be formed of a multilayer film in which one or more inorganic layers of silicon nitride, silicon oxynitride, silicon oxide, titanium oxide, and aluminum oxide are alternately stacked. The buffer film BF may be omitted.

[0151] The thin film transistor 120 is formed on the buffer film BF. The thin film transistor 120 includes an active layer 121, a gate electrode 122, a source electrode 123, and a drain electrode 124. Figure 7 1 shows that the thin film transistor 120 is formed by a top-gate method in which the gate electrode 122 is located on the active layer 121, but it should be noted that the inventive concept is not limited thereto. That is, the thin film transistor 120 can be formed by a bottom-gate method in which the gate electrode 122 is located below the active layer 121, or can be formed by a dual-gate method in which the gate electrode 122 is located both above and below the active layer 121.

[0152] The active layer 121 is formed on the buffer film BF. The active layer 121 may include an oxide semiconductor or an inorganic semiconductor such as polycrystalline silicon, single crystal silicon, low temperature polycrystalline silicon, or amorphous silicon. A light blocking layer for blocking external light incident on the active layer 121 may be formed between the buffer film BF and the active layer 121.

[0153] The gate insulating film 130 may be formed on the active layer 121. The gate insulating film 130 may be formed of an inorganic layer (eg, a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer).

[0154] The gate electrode 122 and the gate line may be formed on the gate insulating film 130. The gate electrode 122 and the gate line may be formed of a single layer or multiple layers including at least one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu), or alloys thereof.

[0155] An interlayer insulating film 140 may be formed on the gate electrode 122 and the gate line. The interlayer insulating film 140 may be formed of an inorganic layer (eg, a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer).

[0156] The source electrode 123 and the drain electrode 124 may be formed on the interlayer insulating film 140. Each of the source electrode 123 and the drain electrode 124 may be connected to the active layer 121 through a contact hole penetrating the gate insulating film 130 and the interlayer insulating film 140. The source electrode 123 and the drain electrode 124 may be formed of a single layer or a multilayer including at least one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu), or an alloy thereof.

[0157] A protective film 150 for insulating the thin film transistor 120 may be formed on the source electrode 123 and the drain electrode 124. The protective film 150 may be formed of an inorganic layer such as a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer.

[0158] A planarization film 160 for planarizing a step caused by the thin film transistor 120 may be formed on the protective film 150. The planarization film 160 may be formed of an organic film including acrylic resin, epoxy resin, phenol resin, polyamide resin, or polyimide resin.

[0159] The light emitting element layer EML is formed on the thin film transistor layer TFTL. The light emitting element layer EML includes a light emitting element 170 and a pixel defining layer 180.

[0160] The light emitting elements 170 and the pixel defining film 180 are formed on the planarization film 160. Each of the light emitting elements 170 may include a first electrode 171, an organic light emitting layer 172, and a second electrode 173.

[0161] The first electrode 171 may be formed on the planarization film 160. The first electrode 171 is connected to the drain electrode 124 of the thin film transistor 120 through a contact hole penetrating the protection film 150 and the planarization film 160.

[0162] In a top emission structure in which light is emitted toward the second electrode 173 relative to the organic light-emitting layer 172, the first electrode 171 may be formed of a metal material having high reflectivity, such as a stacked structure of aluminum and titanium (Ti / Al / Ti), a stacked structure of aluminum and ITO (ITO / Al / ITO), an APC alloy, or a stacked structure of APC and ITO (ITO / APC / ITO). The APC alloy is an alloy of silver (Ag), palladium (Pd), and copper (Cu).

[0163] In a bottom emission structure in which light is emitted toward the first electrode 171 relative to the organic light-emitting layer 172, the first electrode 171 may be formed of a light-transmitting transparent conductive material (TCO) such as ITO or IZO, or a semi-transmitting conductive material such as magnesium (Mg), silver (Ag), or an alloy of magnesium (Mg) and silver (Ag). In this case, when the first electrode 171 is formed of a semi-transmitting conductive material, light emission efficiency can be improved due to the microcavity.

[0164] A pixel defining film 180 may be formed on the planarization film 160 to divide the first electrode 171, thereby defining the pixels P. The pixel defining film 180 may be formed to cover edges of the first electrode 171. The pixel defining film 180 may be formed of an organic film including acrylic resin, epoxy resin, phenolic resin, polyamide resin, or polyimide resin.

[0165] Each of the pixels P represents a region where a first electrode 171 , an organic light emitting layer 172 , and a second electrode 173 are sequentially stacked, and holes from the first electrode 171 are combined with electrons from the second electrode 173 to emit light.

[0166] The organic light-emitting layer 172 is formed on the first electrode 171 and the pixel defining film 180. The organic light-emitting layer 172 may include an organic material to emit light of a predetermined color. For example, the organic light-emitting layer 172 may include a hole transport layer, an organic material layer, and an electron transport layer. In this case, the organic light-emitting layer 172 of the red pixel may emit red light, the organic light-emitting layer 172 of the green pixel may emit green light, and the organic light-emitting layer 172 of the blue pixel may emit blue light. Alternatively, the organic light-emitting layer 172 of the pixel P may emit white light, and in this case, the red pixel may further include a red color filter layer, the green pixel may further include a green color filter layer, and the blue pixel may further include a blue color filter layer.

[0167] The second electrode 173 is formed on the organic light emitting layer 172 . The second electrode 173 may be formed to cover the organic light emitting layer 172 . The second electrode 173 may be a common layer commonly formed in the pixels P. A capping layer may be formed on the second electrode 173 .

[0168] In a top emission structure, the second electrode 173 may be formed of a light-transmitting transparent conductive material (TCO) such as ITO or IZO, or a semi-transmitting conductive material such as magnesium (Mg), silver (Ag), or an alloy of magnesium (Mg) and silver (Ag). When the second electrode 173 is formed of a semi-transmitting conductive material, light emission efficiency can be improved due to the microcavity.

[0169] In a bottom emission structure, the second electrode 173 may be formed of a metal material having high reflectivity, such as a stacked structure of aluminum and titanium (Ti / Al / Ti), a stacked structure of aluminum and ITO (ITO / Al / ITO), an APC alloy, or a stacked structure of APC and ITO (ITO / APC / ITO). The APC alloy is an alloy of silver (Ag), palladium (Pd), and copper (Cu).

[0170] A second substrate SUB2 is disposed on the light emitting element layer EML, and a touch sensor layer TSL is formed on the second substrate SUB2. The touch sensor layer TSL may include a first touch electrode TE, a second touch electrode RE, a connecting electrode CE, a first-first touch electrode TEa, a second-first touch electrode REa, capacitance compensation patterns TEb and REb, first touch signal lines TL11 to TL1p, second touch signal lines TL21 to TL2p, third touch signal lines RL1 to RLq, guard lines GL1, GL2, GL3, and GL4, and ground lines GRL1 and GRL2.

[0171] For ease of explanation, Figure 7Only the first touch electrodes TE of the touch sensor layer TSL, the first touch island electrodes TEI disposed between the first touch electrodes TE, and the connecting electrode CE are shown. The first-first touch electrode TEa and the second-first touch electrode REa are referred to as the first touch electrode TE and the second touch electrode RE, respectively, whose shapes are cut by the third bent portion CR3 and the fourth bent portion CR4.

[0172] The connection electrodes CE and the capacitance compensation patterns TEb and REb are formed on the second substrate SUB2. Each of the connection electrodes CE connects the first touch electrode TE and the first touch island electrode TE1. That is, one end of each of the connection electrodes CE can be connected to the first touch electrode TE through the first contact hole CNT1 of the first insulating film 510, and the other end of each of the connection electrodes CE can be connected to the first touch island electrode TE1 through the second contact hole CNT2 of the first insulating film 510.

[0173] Each of the connection electrode CE and the capacitance compensation patterns TEb and REb may be formed of an opaque metal conductive layer. For example, each of the connection electrode CE and the capacitance compensation patterns TEb and REb may be formed of a single layer or multiple layers including at least one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu), or alloys thereof. For example, the connection electrode CE and the capacitance compensation patterns TEb and REb may include the same material, but the inventive concept is not limited thereto.

[0174] As described above, the capacitance compensation patterns TEb and REb may be provided in the second touch sensor area TSA2. The first capacitance compensation pattern TEb is provided to be spaced apart and insulated from the second capacitance compensation pattern REb. The first capacitance compensation pattern TEb may be integrally formed on a plane, and the second capacitance compensation pattern REb may be integrally formed on a plane.

[0175] The first capacitance compensation pattern TEb and the second capacitance compensation pattern REb can each be arranged to overlap the adjacent first-first touch electrode TEa and the adjacent second-first touch electrode REa in the thickness direction. In addition, each of the first capacitance compensation pattern TEb and the second capacitance compensation pattern REb can also be arranged to overlap the gap between the first-first touch electrode TEa and the second-first touch electrode REa in the thickness direction.

[0176] The first capacitance compensation pattern TEb can be electrically connected to the first-first touch electrode TEa through the third contact hole CNT3 of the first insulating film 510, and the second capacitance compensation pattern REb can be electrically connected to the second-first touch electrode REa through the fourth contact hole CNT4 of the first insulating film 510. In the embodiment, one third contact hole CNT3 and one fourth contact hole CNT4 are provided, but the inventive concept is not limited thereto. A plurality of third contact holes CNT3 and a plurality of fourth contact holes CNT4 may be provided, and their positions are not limited.

[0177] That is, the first capacitance compensation pattern TEb can be electrically connected to the first-first touch electrode TEa, and the second capacitance compensation pattern REb can be electrically connected to the second-first touch electrode REa, thereby compensating for the capacitance reduced due to the area of ​​the first-first touch electrode TEa and the second-first touch electrode REa being reduced by the fourth curved portion CR4.

[0178] The capacitance compensation patterns TEb and REb may each have an extension pattern and a main pattern. The extension patterns of the capacitance compensation patterns TEb and REb may each branch from the main pattern in one direction. For example, Figure 8 As shown in , the first capacitance compensation pattern TEb may include a plurality of extension patterns extending from the main pattern in a direction between a first direction (X-axis direction) and a second direction (Y-axis direction) on a plane, or in an upper right direction. Similar to the first capacitance compensation pattern TEb, the second capacitance compensation pattern REb may include a plurality of extension patterns extending from the main pattern in a direction between a first direction (X-axis direction) and a second direction (Y-axis direction) on a plane, or in a lower left direction.

[0179] The plurality of extension patterns of the first capacitance compensation pattern TEb and the plurality of extension patterns of the second capacitance compensation pattern REb may be arranged alternately. Figure 8As shown in , the first capacitance compensation pattern TEb may include a first-first extension pattern TEb11 closest to the first touch sensor area TSA1 and a first-second extension pattern TEb12 physically connected to the first-first extension pattern TEb11. The second capacitance compensation pattern REb may include a second-first extension pattern REb11 closest to the first touch sensor area TSA1 and a second-second extension pattern REb12 physically connected to the second-first extension pattern REb11. The first-first extension pattern TEb11, the second-first extension pattern REb11, the first-second extension pattern TEb12, and the second-second extension pattern REb12 may be arranged sequentially adjacent to the first touch sensor area TSA1. That is, the second-first extension pattern REb11 may be disposed between the first-first extension pattern TEb11 and the first-second extension pattern TEb12, and the first-second extension pattern TEb12 may be disposed between the second-first extension pattern REb11 and the second-second extension pattern REb12.

[0180] Despite Figure 8 , it is shown that each of the capacitance compensation patterns TEb and REb has two extension patterns, but the inventive concept is not limited thereto, and each of the capacitance compensation patterns TEb and REb may have one extension pattern or three or more extension patterns.

[0181] In addition, the extension directions of the extension patterns of the capacitance compensation patterns TEb and REb are not limited thereto. For example, the extension directions of the extension patterns of the capacitance compensation patterns TEb and REb may be the upper left direction and the lower right direction from the main pattern, respectively.

[0182] In some embodiments, the capacitance compensation patterns TEb and REb may include a plurality of extension patterns spaced apart from each other without including a main pattern. In this case, the extension pattern of each of the capacitance compensation patterns TEb and REb may electrically contact the first-first touch electrode TEa and the second-first touch electrode REa located in the adjacent second touch sensor area TSA2, respectively.

[0183] A first insulating film 510 is formed on the connection electrode CE and the capacitance compensation patterns TEb and REb. The first insulating film 510 may be formed of an inorganic layer (e.g., a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer). The first insulating film 510 may include the contact holes CNT1 to CNT4 described above.

[0184] The first touch electrode TE, the first touch island electrode TEI, the second touch electrode RE, the first-first touch electrode TEa, and the second-first touch electrode REa are disposed on the first insulating film 510 .

[0185] As described above, compared with the area of ​​the first touch electrode TE and the area of ​​the second touch electrode RE located at the edges of the first-first touch electrode TEa and the second-first touch electrode REa, the area of ​​the first-first touch electrode TEa and the area of ​​the second-first touch electrode REa are reduced by the fourth bent portion CR4 of the touch sensing unit TDU, and the area of ​​the first-first touch electrode TEa and the area of ​​the second-first touch electrode REa can be smaller than the area of ​​the first touch electrode TE and the area of ​​the second touch electrode RE whose areas are reduced by the first bent portion CR1.

[0186] Therefore, the capacitance charging rate is reduced by the first-first touch electrode TEa and the second-first touch electrode REa, the second touch electrode RE connected to the second-first touch electrode REa, and the first touch electrode TE connected to the first-first touch electrode TEa via the connection electrode CE. Therefore, in the touch sensor area TSA provided with the first-first touch electrode TEa and the second-first touch electrode REa, the second touch electrode RE connected to the second-first touch electrode REa, and the first touch electrode TE connected to the first-first touch electrode TEa via the connection electrode CE, the touch detection power in the corresponding area is degraded.

[0187] However, the touch sensing unit TDU may pattern the metal shielding film provided on the same layer as the connecting electrode CE to prevent light leakage in the second touch sensor area TSA2, and may include capacitance compensation patterns TEb and REb electrically connected to the first-first touch electrode TEa and the second-first touch electrode REa whose areas are reduced, thereby compensating for capacitance caused by the first-first touch electrode TEa and the second-first touch electrode REa whose areas are reduced by the fourth bent portion CR4.

[0188] That is to say, if Figure 8 and Figure 11As shown in FIG, a second capacitor Cm2 between the first capacitance compensation pattern TEb and the second capacitance compensation pattern REb, a third capacitor Cm3 between the second-first touch electrode REa and the first capacitance compensation pattern TEb, a fourth capacitor Cm4 between the first-first touch electrode TEa and the second capacitance compensation pattern REb, and a first capacitor Cm1 caused by the first-first touch electrode TEa and the second-first touch electrode REa are further provided to compensate for the capacitance caused by the first-first touch electrode TEa and the second-first touch electrode REa due to the reduction in area by the fourth bent portion CR4. Therefore, in the touch sensor area TSA provided with the first-first touch electrode TEa and the second-first touch electrode REa, the second touch electrode RE connected to the second-first touch electrode REa, and the first touch electrode TE connected to the first-first touch electrode TEa via the connecting electrode CE, degradation of touch detection power in the corresponding area can be prevented.

[0189] In addition, in an embodiment of the present disclosure, a second insulating film 520 may be formed on the first touch electrode TE, the first touch island electrode TE1, the second touch electrode RE, the first-first touch electrode TEa, and the second-first touch electrode REa. The second insulating film 520 may be formed of an inorganic layer (e.g., a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer). However, the present disclosure is not limited thereto.

[0190] Hereinafter, display devices according to other exemplary embodiments will be described. In the following exemplary embodiments, components identical to those of the already described embodiments are denoted by the same reference numerals, and repeated descriptions thereof will be omitted or simplified.

[0191] Figure 12 is an enlarged plan view illustrating a touch sensor area and a touch peripheral area according to another exemplary embodiment.

[0192] Reference Figure 12 The touch sensor layer TSL_1 according to the present exemplary embodiment is different from the aforementioned touch sensor layer TSL in that a plurality of capacitance compensation patterns TEb_1 and REb_1 are provided in the touch peripheral area TPA.

[0193] More specifically, the touch sensor layer TSL_1 according to this exemplary embodiment may include a first capacitance compensation pattern TEb_1 electrically connected to the first-first touch electrode TEa and a second capacitance compensation pattern REb_1 electrically connected to the second-first touch electrode REa in the touch peripheral area TPA (specifically, the touch peripheral area TPA adjacent to the fourth curved portion CR4 of the touch sensing unit TDU).

[0194] The first capacitance compensation pattern TEb_1 may contact the first-first touch electrode TEa through the third contact hole CNT3_1 of the first insulating film 510 , and the second capacitance compensation pattern REb_1 may contact the second-first touch electrode REa through the fourth contact hole CNT4_1 of the first insulating film 510 .

[0195] The first and second capacitance compensation patterns TEb_1, REb_1 may be formed on the same layer as the connection electrode CE. The first and second capacitance compensation patterns TEb_1, REb_1 may be disposed on the same layer as the metal shielding film pattern LSP and may be electrically insulated from the metal shielding film pattern LSP. In other words, the first and second capacitance compensation patterns TEb_1, REb_1 may be physically separated from the metal shielding film pattern LSP.

[0196] The first capacitance compensation pattern TEb_1 may include a plurality of first extension patterns TEb11_1 and TEb12_1 and a first connection pattern connecting adjacent first extension patterns TEb11_1 and TEb12_1. The second capacitance compensation pattern REb_1 may include a plurality of second extension patterns REb11_1 and REb12_1 and a second connection pattern connecting adjacent second extension patterns REb11_1 and REb12_1. The first extension patterns TEb11_1 and TEb12_1 and the second extension patterns REb11_1 and REb12_1 may be arranged alternately. For example, in the first capacitance compensation pattern TEb_1, the first extension pattern TEb11_1 closest to the fourth curved portion CR4 may extend in the upper right direction, the first connection pattern may extend from the end of the first extension pattern TEb11_1 extending in the upper right direction toward the lower right direction, and the first extension pattern TEb12_1 may extend from the end of the first connection pattern extending in the lower right direction toward the lower left direction. In the second capacitance compensation pattern REb_1, the second extension pattern REb11_1 can extend in the lower left direction, the second connection pattern can extend from the end of the second extension pattern REb11_1 extending in the lower left direction toward the upper left direction, and the second extension pattern REb12_1 can extend from the end of the second connection pattern extending in the upper left direction toward the upper right direction again.

[0197] Figure 13 is an enlarged plan view illustrating a touch sensor area and a touch peripheral area according to still another exemplary embodiment.

[0198] Reference Figure 13 The touch sensor layer TSL_2 according to the present exemplary embodiment is different from the aforementioned touch sensor layer TSL in the shapes of the first-first touch electrode TEa_1 and the second-first touch electrode REa_1.

[0199] More specifically, the first-first touch electrode TEa_1 and the second-first touch electrode REa_1 of the touch sensor layer TSL_2 may include a plurality of extension patterns extending toward each other. Figure 13 As shown in , the multiple extension patterns of the first-first touch electrode TEa_1 and the second-first touch electrode REa_1 may be arranged alternately. That is, the extension patterns of the second-first touch electrode REa_1 may be arranged between the extension patterns of the first-first touch electrode TEa_1. In addition, the extension patterns of the first-first touch electrode TEa_1 may be arranged between the extension patterns of the second-first touch electrode REa_1.

[0200] Figure 14 is a plan view specifically illustrating an example of a touch sensing unit according to still another exemplary embodiment, Figure 15 is an enlarged plan view illustrating a touch sensor area and a touch peripheral area according to still another exemplary embodiment.

[0201] Reference Figure 14 and Figure 15 , the touch sensing unit according to the present exemplary embodiment is different from the aforementioned touch sensing unit in that its planar shape includes a groove shape recessed from one edge.

[0202] More specifically, the touch sensor area TSA_1 of the touch sensing unit according to the present exemplary embodiment may include first to fourth touch sensor areas TSA1 to TSA4. The first touch sensor area TSA1 may have a rectangular shape on a plane. The first touch sensor area TSA1 may occupy most of the touch sensor area TSA_1.

[0203] Since the second touch sensor area TSA2 is the same as the above reference Figure 5 The description of the second touch sensor area TSA2 is the same, so any redundant description will be omitted.

[0204] The third touch sensor area TSA3 and the fourth touch sensor area TSA4 may protrude from one side of the first touch sensor area TSA1. The third touch sensor area TSA3 may protrude from one corner of one side of the first touch sensor area TSA1, and the fourth touch sensor area TSA4 may protrude from another corner of one side of the first touch sensor area TSA1. Therefore, the touch sensor area TSA_1 may further include a recessed area EA having a shape in which the center of one side is recessed. In addition, the recessed area EA may be provided between the third touch sensor area TSA3 and the fourth touch sensor area TSA4 in the first direction (X-axis direction). The recessed area EA may have a groove shape recessed from one edge of the touch sensing unit. As Figure 14 As shown in , the recessed area EA may have a rectangular shape in a plane, but the inventive concept is not limited thereto, and other shapes such as a square, a V-shape, a circle, and an ellipse may be applied to the recessed area EA.

[0205] In the recessed area EA, some second touch signal lines TL22 to TL2p and third connection lines CL3 for connecting the second touch electrodes of the third touch sensor area TSA3 to the second touch electrodes of the fourth touch sensor area TSA4 may be provided. Therefore, the second touch signal lines TL22 to TL2p and the third connection lines CL3 intersect with each other in the recessed area EA of the plane, but may be provided on different layers and may be insulated from each other.

[0206] Furthermore, since the second touch signal lines TL22 to TL2p are disposed within the recessed area EA, an empty area can be disposed outside one side of the recessed area EA in the second direction (the Y-axis direction). When the display device 10 is implemented as a mobile phone, smartphone, tablet, or the like, a camera device, a proximity sensor device, an illumination sensor device, an iris recognition sensor device, or the like can be disposed so as to overlap the empty area. Consequently, a separate bezel area for accommodating the camera device, proximity sensor device, illumination sensor device, iris recognition sensor device, or the like of the mobile phone, smartphone, tablet, or the like can be omitted. Consequently, the bezel area on one side of the mobile phone, smartphone, tablet, or the like can be reduced.

[0207] The first-first touch electrode TEa_2 and the second-first touch electrode REa_2 adjacent to the recessed area EA may have a shape cut by the recessed area EA.

[0208] A plurality of capacitance compensation patterns TEb_2 and REb_2 may be further disposed between the recessed area EA of the plane and the third and fourth touch sensor areas TSA3 and TSA4. The plurality of capacitance compensation patterns TEb_2 and REb_2 may be electrically connected to adjacent first-first touch electrodes TEa_2 and second-first touch electrodes REa_2 through third and fourth contact holes CNT3_2 and CNT4_2, respectively.

[0209] As already referred to above Figure 12 The shapes and functions of the plurality of capacitance compensation patterns TEb_2 and REb_2 are described, so any redundant description will be omitted.

[0210] Figure 16 is a plan view specifically illustrating an example of a touch sensing unit according to still another exemplary embodiment.

[0211] Reference Figure 16According to the present exemplary embodiment, the touch sensing unit and Figure 14 The difference between the touch sensing unit of the exemplary embodiment is that the recessed area EA_1 of the touch sensing unit of the exemplary embodiment has a U shape or an Ω shape. Figure 14 and Figure 15 The details of the touch sensing unit are described, so redundant description will be omitted.

[0212] Figure 17 is a plan view of a display device according to another exemplary embodiment; Figure 18 It shows Figure 17 a cross-sectional view of an example of; Figure 19 Specifically shows that Figure 17 a plan view of an example of a display unit of an exemplary embodiment; Figure 20 Specifically shows that Figure 17 A plan view of an example of a touch sensing unit of an exemplary embodiment; Figure 21 yes Figure 20 Enlarged plan view.

[0213] Reference Figures 17 to 21 The display device 11 according to the present exemplary embodiment is different from the aforementioned display device 10 in that the display panel 100 of the display device 11 according to the present exemplary embodiment includes a main area MA and a protrusion area PA protruding from the main area MA.

[0214] The display device 11 according to this exemplary embodiment includes a display panel 100, a display driver circuit 200, a circuit board 300, and a touch driver circuit 400. The display panel 100 may include a main area MA and a protrusion area PA protruding from one side of the main area MA. The main area MA may have a rectangular planar shape with a short side in a first direction (X-axis direction) and a long side in a second direction (Y-axis direction) intersecting the first direction (X-axis direction). The corner where the short side in the first direction (X-axis direction) meets the long side in the second direction (Y-axis direction) may be rounded with a predetermined curvature or have a right angle. The planar shape of the display device 11 is not limited to a rectangle and may be another polygonal shape, a circle, or an ellipse. The main area MA may be flat, but the inventive concept is not limited thereto. The main area MA may include curved portions formed at its left and right ends. In this case, the curved portions may have a constant curvature or a variable curvature.

[0215] The main area MA may include a display area DA where pixels are formed to display an image and a non-display area NDA which is a peripheral area of ​​the display area DA.

[0216] In the display area DA, not only pixels but also scan lines, data lines, and power lines connected to the pixels can be arranged. When the main area MA includes a curved portion, the display area DA can be arranged in the curved portion. In this case, the image of the display panel 100 can be seen even on the curved portion.

[0217] The non-display area NDA may be defined as a region from the outside of the display area DA to the edge of the display panel 100. In the non-display area NDA, a scan driver for applying a scan signal to a scan line and a data connection line for connecting a data line to the display driving circuit 200 may be disposed.

[0218] The protrusion area PA may protrude from one side of the main area MA. Figure 17 As shown in , the protrusion area PA may protrude from the lower side of the main area MA. The length of the protrusion area PA in the first direction (X-axis direction) may be shorter than the length of the main area MA in the first direction (X-axis direction).

[0219] The protrusion area PA may include a bending area BA and a pad area PDA. In this case, the pad area PDA may be provided on one side of the bending area BA, and the main area MA may be provided on the other side of the bending area BA. For example, the pad area PDA may be provided on the lower side of the bending area BA, and the main area MA may be provided on the upper side of the bending area BA.

[0220] The display panel 100 can be formed to be flexible, allowing it to be bent, curved, folded, or rolled. Therefore, the display panel 100 can be bent from the bending area BA in the thickness direction (Z-axis direction). In this case, before the display panel 100 is bent, one side of the pad area PDA of the display panel 100 faces upward, but after the display panel 100 is bent, one side of the pad area PDA of the display panel 100 faces downward. Therefore, since the pad area PDA is disposed below the main area MA, it can overlap the main area MA.

[0221] The pad area PDA of the display panel 100 may be provided with pads electrically connected to the display driving circuit 200 and the circuit board 300. The pads may include display electrode pads electrically connected to the display driving circuit 200 and the circuit board 300 and touch electrode pads electrically connected to touch lines.

[0222] The touch driving circuit 400 may be provided on the circuit board 300 . The touch driving circuit 400 may be formed as an integrated circuit (IC) and mounted on the circuit board 300 .

[0223] like Figure 18As shown in FIG, in the display device 11 according to the present exemplary embodiment, the second substrate SUB2 is omitted, and the touch sensor layer TSL_5 may be provided on the thin film encapsulation layer TFEL.

[0224] The thin film encapsulation layer TFEL may be provided in both the display area DA and the non-display area NDA. Specifically, the thin film encapsulation layer TFEL may be provided to cover the thin film transistor layer TFTL and the light emitting element layer EML in the non-display area NDA and the display area DA.

[0225] The touch sensor layer TSL_5 may be disposed on the thin film encapsulation layer TFEL. Since the touch sensor layer TSL_5 is disposed directly on the thin film encapsulation layer TFEL, the thickness of the display device 11 may be reduced compared to when a separate touch panel including the touch sensor layer TSL_5 is attached to the thin film encapsulation layer TFEL.

[0226] Reference Figure 19 and Figure 20 , the display electrode pads DP may be arranged in the pad area PDA of the protrusion area PA of the display panel 100 , and the touch electrodes TE and RE may be arranged in a grid form.

[0227] The display electrode pad DP may be disposed at one end of the protrusion area PA of the display panel 100 .

[0228] The drive electrodes TE and sensing electrodes RE can be formed as a grid of electrodes. When the touch sensor layer TSL_5, including the drive electrodes TE and sensing electrodes RE, is formed directly on the thin-film encapsulation layer TFEL, the second electrode of the light-emitting element layer EML is close to the drive electrodes TE or sensing electrodes RE of the touch sensor layer TSL_5. Consequently, a very large parasitic capacitance is formed between the second electrode of the light-emitting element layer EML and the drive electrodes TE or sensing electrodes RE of the touch sensor layer TSL_5. Therefore, to reduce parasitic capacitance, the drive electrodes TE and sensing electrodes RE are preferably formed as a grid of electrodes, compared to a case where the drive electrodes TE and sensing electrodes RE are formed as unpatterned electrodes of a transparent oxide conductive layer including ITO or IZO.

[0229] The adjacent first-first touch electrode TEa_3 and second-first touch electrode REa_3 may have a shape cut by the fourth curved portion CR4 of the touch sensing unit.

[0230] Even in this exemplary embodiment, a plurality of capacitance compensation patterns TEb_3 and REb_3 may be further provided in the second touch sensor area TSA2, and the plurality of capacitance compensation patterns TEb_3 and REb_3 may be electrically connected to the adjacent first-first touch electrodes TEa_3 and second-first touch electrodes REa_3 through the third contact hole CNT3_3 and the fourth contact hole CNT4_3, respectively. Figures 8 to 10 The shapes and functions of the capacitance compensation patterns TEb_3 and REb_3 are described, so redundant description will be omitted.

[0231] Figure 22 is an enlarged plan view illustrating a touch sensor area and a touch peripheral area according to still another exemplary embodiment.

[0232] Reference Figure 22 According to the present exemplary embodiment, the touch sensor layer TSL_6 and Figures 17 to 21 The difference of the touch sensor layer TSL_5 is that: Figure 12 The multiple capacitance compensation patterns TEb_1 and REb_1 are substantially the same as the multiple capacitance compensation patterns TEb_4 and REb_4, instead of Figures 17 to 21 Multiple capacitance compensation patterns TEb_3 and REb_3.

[0233] The plurality of capacitance compensation patterns TEb_4 and REb_4 may be electrically connected to the adjacent first-first touch electrodes TEa_3 and second-first touch electrodes REa_3 through the third contact hole CNT3_4 and the fourth contact hole CNT4_4, respectively. Figure 12 The shapes and functions of the capacitance compensation patterns TEb_4 and REb_4 are described, so any redundant description will be omitted.

[0234] Figure 23 is a plan view of a display device according to yet another exemplary embodiment; Figure 24 It shows Figure 23 a cross-sectional view of an example of; Figure 25 Specifically shows that Figure 23 A plan view of an example of a touch sensing unit of an exemplary embodiment; Figure 26 yes Figure 25 Enlarged plan view.

[0235] Reference Figures 23 to 26 The display device 12 according to this exemplary embodiment is different from the aforementioned display device 10 in that the display device 12 according to this exemplary embodiment includes a display area DA including a plurality of pixels and a first non-display area NDA1 and a second non-display area NDA2 that are arranged around the display area DA and do not display an image.

[0236] As already referred to above Figure 17 Details of the display area DA and the first non-display area NDA1 are described, so any redundant description will be omitted.

[0237] In the display device 12 according to the present exemplary embodiment, the penetration pattern may include a through hole TH, the through hole TH may penetrate the display device 12 in the third direction (Z-axis direction), and the electronic element EMD may be disposed in the through hole TH.

[0238] In some embodiments, as shown in the drawings, the planar shape of the through hole TH may be a circular shape, but is not limited thereto. The planar shape of the through hole TH may be variously modified, such as a polygon, a combination of straight lines and curves, and an ellipse.

[0239] The second non-display area NDA2 of the display device 12 may surround the through hole TH in a plan view. The display area DA may surround the second non-display area NDA2 in a plan view.
