DETAILED DESCRIPTION

[0012] In the following description, for the purpose of explanation, many specific details are set forth to provide a thorough understanding of various exemplary embodiments. As used herein, the terms "embodiment" and "implementation method" are used interchangeably and are non-limiting examples of one or more inventive concepts disclosed herein. However, it is apparent that various exemplary embodiments may be implemented without these specific details or with one or more equivalent arrangements. In other cases, in order to avoid making various exemplary embodiments unnecessarily obscure, known structures and devices are shown in block diagram form. In addition, various exemplary embodiments may be different, but need not be exclusive. For example, without departing from the inventive concept, the specific shape, construction and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0013] Unless otherwise specified, the illustrated exemplary embodiments will be understood as providing exemplary features of different details of the exemplary embodiments. Therefore, unless otherwise specified, various exemplified features, components, modules, layers, films, panels, regions and / or aspects, etc. (hereinafter, individually or collectively referred to as "elements" or "multiple elements") may be further combined, separated, interchanged and / or rearranged without departing from the inventive concept.

[0014] The use of cross hatching and / or shadows is usually provided in the drawings to make the boundaries between adjacent elements clear. Thus, unless otherwise specified, the presence and absence of cross hatching or shadows do not express or indicate 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 drawings, the size and relative size of the elements can be exaggerated for clarity and / or descriptive purposes. Thus, the size and relative size of each element are not necessarily limited to the size and relative size shown in the figures. When the exemplary embodiment can be implemented differently, the specific process sequence can be performed in a different order from that described. For example, two processes described in succession can be performed substantially simultaneously or in an order opposite to that described. In addition, the same reference numerals represent the same elements.

[0015] When an element such as a layer is referred to as being "on" another element, "connected to" or "bonded to" another element, the element may be directly on, directly connected to or directly bonded to the other element, or there may be intervening elements. However, when an element is referred to as being "directly on" another element, "directly connected to" or "directly bonded to" another element, there are no intervening elements. Other terms and / or phrases used to describe the relationship between elements should be interpreted in a similar manner, for example, "between" versus "directly between", "adjacent" versus "directly adjacent", "above" versus "directly above", etc. In addition, the term "connected" may refer to a physical connection, an electrical connection, and / or a fluid connection. In addition, the DR1 axis, the DR2 axis, and the DR3 axis are not limited to the three axes of a rectangular coordinate system, and may be interpreted in a broader sense. For example, the DR1 axis, the DR2 axis, and the DR3 axis may be perpendicular to each other, or may represent different directions that are not perpendicular to each other. For the purpose 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 understood as any combination of only X, only Y, only Z, or two or more of X, Y, and Z, such as, for example, XYZ, XYY, YZ, and ZZ. As used herein, the term "and / or" includes any and all combinations of one or more of the relevant listed items.

[0016] Although the terms "first", "second", etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used to distinguish one element from another element. Therefore, the first element discussed below may be named as the second element without departing from the disclosed teachings.

[0017] For descriptive purposes, spatially relative terms such as "under," "below," "below," "down," "above," "up," "above," "higher," "side" (e.g., as in "sidewall"), etc., may be used herein to describe the relationship of one element to another (other) element as shown in the accompanying drawings. Spatially relative terms are intended to include different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, an element or feature described as "under" or "beneath" other elements or features will then be positioned as "above" the other elements or features. Thus, the exemplary term "under" can include both above and below orientations. In addition, the device can be positioned otherwise (e.g., rotated 90 degrees or at other orientations), so that the spatially relative descriptors used herein are interpreted accordingly.

[0018] 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 "one", "one (kind / person)" and "said (the)" are also intended to include plural forms. In addition, when the terms "comprise" and / or "include" and their variations are used in this specification, the stated features, integral bodies, steps, operations, elements, components and / or their groups are indicated, but the presence or addition of one or more other features, integral bodies, steps, operations, elements, components and / or their groups are not excluded. It should also be noted that, as used herein, the terms "substantially", "approximately" and other similar terms are used as approximate terms rather than as terms of degree, so that 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.

[0019] Various exemplary embodiments are described herein with reference to cross-sectional views, isometric views, perspective views, plan 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 to be expected. Therefore, the exemplary embodiments disclosed herein should not be construed as limited to the specific illustrated shapes of the regions, but rather are to include deviations in shape due to, for example, manufacturing. To this end, the regions illustrated in the drawings may be schematic in nature, and the shapes of these regions may not reflect the actual shapes of the regions of the device, and as such, no limitation is intended.

[0020] Unless otherwise defined, all terms (including technical and scientific terms) used herein 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 general dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and will not be interpreted in an ideal or overly formal sense unless expressly defined as such herein.

[0021] As is customary in the art, exemplary embodiments are described and illustrated in the accompanying drawings from the perspective of functional blocks, units and / or modules. It will be understood by those skilled in the art that these functional blocks, units and / or modules are physically implemented by electronic (or optical) circuits, discrete components, microprocessors, hard-wired circuits, memory elements, wiring connections, etc., such as logic circuits, which can be formed using semiconductor-based manufacturing techniques or other manufacturing techniques. In the case where the functional blocks, units and / or modules are implemented by microprocessors or other similar hardware, they can be programmed and controlled using software (e.g., microcode) to perform the various functions discussed herein, and they can be optionally driven by firmware and / or software. It is also contemplated that each functional block, unit and / or module can be implemented by dedicated hardware, or as a combination of dedicated hardware that performs some functions and processors (e.g., one or more programmed microprocessors and related circuits) that perform other functions. In addition, without departing from the inventive concept, each functional block, unit and / or module of the exemplary embodiment can be physically separated into two or more interactive and discrete functional blocks, units and / or modules. Furthermore, the functional blocks, units and / or modules of the exemplary embodiments may be physically combined into more complex functional blocks, units and / or modules without departing from the inventive concept.

[0022] Hereinafter, various exemplary embodiments will be explained in detail with reference to the accompanying drawings.

[0023] Figure 1 is a perspective view of a display device according to an exemplary embodiment. Figure 1 , the display device DD can display an image IM through the front surface IS. The front surface IS is parallel to a surface defined by the first direction axis DR1 and the second direction axis DR2.

[0024] The normal direction of the front surface IS (i.e., the thickness direction of the display device DD) is represented as a third directional axis DR3. The front surface (or top surface) and the rear surface (or bottom surface) of each component, unit, layer, etc. described below are distinguished by the third directional axis DR3. However, the first directional axis DR1, the second directional axis DR2, and the third directional axis DR3 shown in this embodiment may be only examples. In the following, the first direction, the second direction, and the third direction may be directions indicated by the first directional axis DR1, the second directional axis DR2, and the third directional axis DR3, respectively, and respectively indicated by the same reference numerals.

[0025] Although a display device DD having a planar front surface is shown as an exemplary embodiment, the exemplary embodiments are not limited thereto. The display device DD may include a curved front surface or a stereoscopic front surface. The stereoscopic front surface may include a plurality of display areas indicating different directions. For example, the stereoscopic front surface may include a polygonal columnar front surface.

[0026] like Figure 1 The display device DD shown in FIG. 1 may be a rigid display device DD. However, exemplary embodiments are not limited thereto. For example, the display device DD may be a flexible display device DD. According to exemplary embodiments, the display device DD can be applied to a mobile terminal.

[0027] Although Figure 1 Although not shown in the figure, an electronic module, a camera module, a power module, etc. mounted on (or coupled to) a main board may be provided on (in) a frame / casing together with a display device DD to constitute a mobile terminal. The display device DD according to an exemplary embodiment may be applied to large-sized electronic devices such as televisions and monitors, and small and medium-sized electronic devices such as tablet personal computers, navigation units for vehicles, game consoles, and smart watches.

[0028] Reference Figure 1 , the front surface IS of the display device DD includes an active area AA and a peripheral area NAA adjacent to (eg, outside) the active area AA. The active area AA may be an area in which an image IM is displayed and in which an external input TC may also be detected.

[0029] The image IM may include a still image and / or a dynamic image. Figure 1 An icon image is shown as an example of the image IM.

[0030] The external input TC includes a user's input TC applied from the outside. The user's input TC includes various types of external inputs, such as a part of the user's body, light, heat, and / or pressure, etc. It is also contemplated that the external input TC may be a near input, such as hovering or approaching input. Figure 1As seen in FIG. 8 , the user's input TC is shown as being applied to the front surface IS by the user's hand.

[0031] The peripheral area NAA is an area in which the image IM is not displayed, or an area in which the external input TC is not sensed even if an electric signal is applied. Figure 1 As shown in , the active area AA may have a rectangular shape. The peripheral area NAA may surround the active area AA. However, exemplary embodiments are not limited thereto. For example, the shapes of the active area AA and the peripheral area NAA may be relatively designed.

[0032] FIG. 2A to FIG. 2D is a cross-sectional view of a display device according to an exemplary embodiment. For example, FIG. 2A to FIG. 2D The cross section defined by the second direction axis DR2 and the third direction axis DR3 is shown.

[0033] The display device DD according to an exemplary embodiment may include a display unit (or display panel), an input sensing unit (or input sensing sensor), an anti-reflection unit, and a window. At least some of the display panel, the input sensing sensor, the anti-reflection unit, and the window may be formed by a continuous process, and the at least some of the parts may be bonded to each other by a bonding member. Likewise, it will be understood that the parts of the display device DD formed by a continuous process do not use bonding members between adjacent components (e.g., layers, etc.) formed by a continuous process. FIG. 2A to FIG. 2D An optically clear adhesive OCA is shown as an example of a bonding member, but the exemplary embodiment is not limited thereto. Hereinafter, the bonding member may include a common adhesive or bonding agent. In an exemplary embodiment, the anti-reflection unit and the window may be replaced with different components or the anti-reflection unit and the window may be omitted.

[0034] exist FIG. 2A to FIG. 2D In the embodiment of the present invention, the corresponding components among the input sensing sensor, the anti-reflection unit and the window formed by a continuous process relative to other components can be represented as a "layer". The components among the input sensing unit, the anti-reflection unit and the window bonded to other components by bonding members can be represented as a "panel". The "panel" may include a substrate layer providing a substrate surface, such as a synthetic film, a composite material film, and a glass substrate, etc., but the substrate layer can be omitted in the "layer". That is, the unit represented as a "layer" can be arranged on a substrate surface provided by other units (for example, the following unit).

[0035] The display unit, the input sensing unit, the anti-reflection unit and the window may be referred to as a display panel DP, an input sensing panel ISP, an anti-reflection panel RPP and a window panel WP, or a display panel DP, an input sensing layer ISL, an anti-reflection layer RPL and a window layer WL.

[0036] like Figure 2A As shown in , the display device DD may include a display panel DP, an input sensing layer ISL, an anti-reflection panel RPP and a window panel WP. The input sensing layer ISL may be directly disposed on the display panel DP. For the purpose of the present disclosure, when "component B is directly disposed on component A", it means that a separate adhesive layer / adhesive member is not disposed between component A and component B. After component A is formed, component B may be formed on a substrate surface provided by component A by a continuous process.

[0037] The display panel DP and the input sensing layer ISL directly disposed on the display panel DP may be defined as a display module DM. An optically clear adhesive OCA is disposed between the display module DM and the anti-reflection panel RPP and between the anti-reflection panel RPP and the window panel WP.

[0038] The display panel DP generates an image, and the input sensing layer ISL acquires (or detects) coordinate information of the external input TC (e.g., a touch event or a touch interaction).

[0041] The anti-reflection panel RPP according to an exemplary embodiment may include a color filter. The color filter may have a predetermined arrangement. The arrangement of the color filter may be determined in consideration of the color of light emitted from the pixel provided by the display panel DP. The anti-reflection panel RPP may further include a black matrix adjacent to the color filter.

[0042] The anti-reflection panel RPP according to an exemplary embodiment may include a destructive interference structure. For example, the destructive interference structure may include a first reflection layer and a second reflection layer disposed on different layers (or in different layers) from each other. The first reflection light and the second reflection light respectively reflected from the first reflection layer and the second reflection layer may destructively interfere, thereby reducing the reflection of external light.

[0043] The window panel WP according to an exemplary embodiment 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 film. The base layer WP-BS is not limited to a single layer.

[0044] The light-blocking pattern WP-BZ partially overlaps the base layer WP-BS. The light-blocking pattern WP-BZ is disposed on the rear surface of the base layer WP-BS. The light-blocking pattern WP-BZ may be disposed to correspond to the peripheral area NAA of the display device DD. The area in which the light-blocking pattern WP-BZ is not disposed may be set as the active area AA of the display device DD.

[0045] The light blocking pattern WP-BZ may be, for example, a colored organic layer formed by coating. Although not shown, the window panel WP may further include a functional coating layer disposed on the entire surface of the base layer WP-BS. The functional coating layer may include an anti-fingerprint layer, an anti-reflection layer, and / or a hard coating layer, etc. FIG. 2B to FIG. 2D , the window panel WP and the window layer WL will be simply illustrated without distinguishing the base layer WP-BS and the light blocking pattern WP-BZ from each other.

The bonding member may be omitted from the display device DD, and the input sensing layer ISL, the anti-reflection layer RPL, and the window layer WL may be formed on a base surface provided by the display panel DP through a continuous process. Although not shown, it may be possible to Figure 2B and Figure 2C In a similar manner, the stacking order of the input sensing layer ISL and the anti-reflection layer RPL is changed.

The display panel DP may correspond to a display unit to be described later. In an exemplary embodiment, a region corresponding to a region may mean that the regions overlap each other and have the same surface area, but is not limited thereto.

[0056] Figure 4 is a perspective view of an electronic device according to an exemplary embodiment. Figure 5A According to an exemplary embodiment Figure 4 Block diagram of an electronic device. Figure 5B According to an exemplary embodiment Figure 4 hereinafter, reference will be made to Figures 1 to 5B Various exemplary embodiments are described.

[0057] According to an exemplary embodiment, an electronic device EA including a smart phone will be described as an example. The electronic device EA may display an image IM on a display surface FS parallel to each of the first direction DR1 and the second direction DR2 and in a third direction DR3. The display surface FS on which the image IM is displayed may correspond to the front surface of the electronic device EA.

[0058] The electronic device EA according to the exemplary embodiment can sense the user's input TC applied from the outside. However, this is only an example. For example, the electronic device EA can sense the user's input TC applied to the side surface or rear surface of the electronic device EA according to the structure of the electronic device EA. Here, the active area AA can extend to the side surface and / or rear surface of the electronic device EA. The electronic device EA according to the exemplary embodiment can be designed to have various shapes, but is not limited to a specific structure or shape.

[0059] Reference Figure 5A The electronic device EA may include a power module PM, a display device DD, an electronic module EM1, a bracket and a housing EDC (see Figure 4 ).

The display panel unit DPU may correspond to the above-mentioned display panel DP, and the input sensing unit ISU may correspond to the input sensing layer ISL or the input sensing panel ISP. Therefore, as described above, the display device DD may display an image IM and sense an external input TC.

[0061] For example, the display panel unit DPU may be configured to generate an image IM. The image IM generated by the display panel unit DPU may be displayed on the display surface FS through the transmissive area TA to be visible to an external user.

[0062] The input sensing unit ISU detects the external input TC applied from the outside. As described above, the input sensing unit ISU may sense the external input TC provided to the window member WM.

For example, the electronic device EA may include a window member WM, a display device DD, and a housing EDC. The display device DD may include an electronic panel EP, a main circuit board MCB, a first circuit board CB1, and a second circuit board CB2.

[0064] The window member WM may include an insulating panel. For example, the window member WM may be made of glass, plastic, or a combination thereof. The front surface FS of the window member WM may define the front surface of the electronic device EA as described above.

[0065] The transmission area TA may be an optically transparent area. For example, the transmission area TA may be an area having a visible light transmittance of about 90% or more, but exemplary embodiments are not limited thereto.

[0066] The border area BZA may be an area having a relatively smaller transmittance than that of the transmission area TA. The border area BZA defines the shape of the transmission area TA. The border area BZA may be arranged adjacent to the transmission area TA to surround the transmission area TA. The border area BZA may have a predetermined color. The border area BZA may cover the peripheral area NAA of the electronic panel EP to prevent the peripheral area NAA from being visible from the outside. However, this is only an example. For example, in a window member WM according to an exemplary embodiment, the border area BZA may be omitted. It is also contemplated that the border area BZA may include one or more openings exposing an underlying electronic module such as a camera module, a sensor module, etc., for example, an electronic module opening EMH.

[0067] The electronic panel EP includes a front surface IS including an active area AA and a peripheral area NAA.

[0068] As described above, the active area AA may be an area activated according to an electrical signal. In an exemplary embodiment, the electronic panel EP may be an area on which a display panel unit DPU (see FIG. 1 ) is disposed. Fig. 6A ) and thereon is disposed an image IM generated by an input sensing unit ISU (see, for example, Figure 6B and Figure 6C ) provides the input sensing area of ​​the component.

[0069] The transmissive area TA overlaps at least the active area AA. For example, the transmissive area TA overlaps the entire surface of at least a portion of the active area AA. Therefore, the user can see the image IM through the transmissive area TA, or provide an external input TC in the transmissive area TA. However, this is only an example. For example, the area of ​​the active area AA where the image is displayed and the area of ​​the active area AA where the external input TC is sensed may be separated from each other, and likewise, the exemplary embodiments are not limited to the specific configuration of the active area AA.

[0070] The peripheral area NAA may be an area covered by the frame area BZA. The peripheral area NAA is adjacent to the active area AA. The peripheral area NAA may surround the active area AA. A driving circuit or driving line for driving the active area AA may be disposed on the peripheral area NAA.

[0071] A plurality of pads (also referred to as pads) PD are schematically shown in the peripheral area NAA. The pads PD are arranged to be spaced apart from each other in the first direction DR1. In an exemplary embodiment, the pads PD may include a plurality of display panel pads DPD and a plurality of input sensing pads TPD.

[0072] The display panel pad DPD is connected to the first circuit board CB1. For ease of description, the display panel pad DPD is shown in a state of being covered and shielded by the first circuit board CB1.

[0073] The input sensing pad TPD is exposed from the first circuit board CB1 and connected to the second circuit board CB2. The input sensing pad TPD may be disposed on two separate areas, and the display panel pad DPD connected to the first circuit board CB1 is disposed between the two separate areas. However, this is only an example. For example, the input sensing pad TPD may be disposed to be biased (or arranged) to one side of the display panel pad DPD, but is not limited thereto.

[0074] The first circuit board CB1 and the second circuit board CB2 may be connected to the pad PD and electrically connected to the display device DD. The first circuit board CB1 and the second circuit board CB2 may be connected to one of the pads PD different from each other.

[0075] The first circuit board CB1 is connected to the display panel pad DPD. The first circuit board CB1 may be a flexible circuit board. The first circuit board CB1 may be electrically connected to the display panel unit DPU of the display device DD through the display panel pad DPD.

[0076] The second circuit board CB2 is connected to the input sensing pad TPD. The second circuit board CB2 may be a flexible circuit board. The second circuit board CB2 may be electrically connected to the input sensing unit ISU of the electronic panel EP through the input sensing pad TPD.

[0077] The second circuit board CB2 may include a first cutoff portion (or first portion) P1, a second cutoff portion (or second portion) P2, and a third cutoff portion (or third portion) P3. The first cutoff portion P1 and the second cutoff portion P2 may be spaced apart from each other in the first direction DR1, and respectively connected to the input sensing pad TPD divided into two regions. The second circuit board CB2 according to an exemplary embodiment includes the first cutoff portion P1 and the second cutoff portion P2 spaced apart from each other, and thus may be easily connected to the input sensing pad TPD arranged to be divided into two regions.

[0078] The third cut-off portion P3 extends in a direction opposite to the direction of each of the first cut-off portion P1 and the second cut-off portion P2. The third cut-off portion P3 may be connected to the main circuit board MCB. Although not shown, a predetermined connector to be connected to the main circuit board MCB may also be provided on the third cut-off portion P3. The second circuit board CB2 may include the third cut-off portion P3 and thus may be easily connected to the main circuit board MCB.

[0079] The main circuit board MCB may include various driving circuits for driving the electronic panel EP and connectors for supplying power. The first circuit board CB1 and the second circuit board CB2 may be connected to the main circuit board MCB, respectively. According to an exemplary embodiment, the electronic panel EP can be easily controlled by one main circuit board MCB. However, this is only an example. In the electronic panel EP according to the exemplary embodiment, the input sensing unit ISU and the display panel unit DPU may be connected to different main circuit boards from each other, and one of the first circuit board CB1 and the second circuit board CB2 may not be connected to the main circuit board MCB, but the exemplary embodiment is not limited to a specific configuration.

[0080] According to an exemplary embodiment, the electronic panel EP can be assembled in a state where the active area AA and the peripheral area NAA are flat and face the window member WM. However, this is only an example. For example, a portion of the peripheral area NAA of the electronic panel EP may be bent. Here, a portion of the peripheral area NAA may be set to face the rear surface of the electronic device EA to reduce the area of ​​the border area BZA on the front surface FS of the electronic device EA. Additionally or optionally, the electronic panel EP may be assembled in a state where a portion of the active area AA is bent. In the electronic panel EP according to an exemplary embodiment, the peripheral area NAA may be omitted.

[0081] Refer again Figure 5A The electronic module EM1 includes various functional modules for driving the electronic device EA. The electronic module EM1 can be directly mounted on the main circuit board MCB electrically connected to the electronic panel EP, or mounted on a separate substrate and then electrically connected to the main circuit board MCB through a connector (not shown).

[0082] The electronic module EM1 may include a control module CM, a wireless communication module TM, an image input module IIM, an audio input module AIM, a memory MM, an external interface IF, an audio output module AOM, a transmitting module (eg, a light emitting module) LM, a light receiving module LRM, and a camera module CMM.

[0083] The control module CM controls the overall operation of the electronic device EA. The control module CM may be a microprocessor. For example, the control module CM may activate or deactivate the electronic panel EP. The control module CM may control other modules (such as an image input module IIM or an audio input module AIM) based on a touch signal received from the electronic panel EP.

[0084] The wireless communication module TM can use, for example, Bluetooth TM The wireless communication module TM can use a general communication line to send / receive audio signals. The wireless communication module TM includes a transmitter TM1 that modulates and sends a signal to be sent and a receiver TM2 that demodulates a received signal.

[0085] The image input module IIM processes the image signal to convert the processed image signal into image data that can be displayed on the electronic panel EP. The audio input module AIM receives an external audio signal using a microphone during a recording mode or a voice recognition mode to convert the received audio signal into electrical sound data.

[0086] The external interface IF serves as an interface connected to an external charger, a wired / wireless data port, and / or a card slot (eg, a memory card and a Subscriber Identity Module (SIM) / User Identity Module (UIM) card).

[0087] The audio output module AOM converts audio data received from the wireless communication module TM or converts audio data stored in the memory MM to output the converted audio data to the outside.

[0088] The transmitting module LM generates and outputs light. The transmitting module LM may output infrared rays. The transmitting module LM may include a light emitting diode (LED).

[0089] The light receiving module LRM may sense infrared rays. The light receiving module LRM may be activated when infrared rays having a predetermined level or higher are sensed. The light receiving module LRM may include a complementary metal oxide semiconductor (CMOS) sensor. Infrared rays generated in the transmitting module LM may be output, and then may be reflected by an external object (e.g., a user's finger or face), and the reflected infrared rays may be incident into the light receiving module LRM. The camera module CMM captures external images.

[0090] Refer again Figure 5B , the housing EDC may be coupled to the window member WM. The housing EDC defines the appearance of the electronic device EA. Although not shown, a receiving member or a bracket may be coupled to the window member WM and / or the housing EDC to define an internal space.

[0091] The housing EDC may include a material having relatively high rigidity. For example, the housing EDC may include a plurality of frames and / or plates made of glass, plastic and / or metal. The housing EDC may stably protect the components of the electronic device EA contained in the internal space from external impacts and / or debris. The various components constituting the electronic device EA may be contained in the internal space of the housing EDC.

[0092] FIG. 6A to FIG. 6C 1 is a plan view showing a portion of some components of an electronic panel according to various exemplary embodiments. For ease of description, Fig. 6A 2 shows a schematic plan view of a display panel unit DPU according to an exemplary embodiment, Figure 6B A schematic plan view of an input sensing unit ISU according to an exemplary embodiment is shown. Figure 6C is a plan view of an input sensing unit ISU_P according to an exemplary embodiment. FIG. 6A to FIG. 6C Various exemplary embodiments are described. The same reference numerals may refer to Figures 1 to 5B The components are the same as those of the components of FIG. 1 , and their detailed description will be omitted.

[0093] like Fig. 6A As shown in FIG. 1 , the display panel unit DPU may include a plurality of signal lines GL, DL, and PL, a plurality of pixels PX, a power pattern VDD, and a plurality of display panel pads DPD. The components of the display panel unit DPU may be disposed on a base substrate BS. For ease of description, Fig. 6A : shows a schematic signal circuit diagram of one pixel PX. Here, signal lines GL, DL, and PL connected to one pixel PX are shown.

[0094] The base substrate BS may provide a front surface IS1 including a first area AA1 and a first peripheral area NAA1. The first area AA1 may correspond to the active area AA (see Figure 5B ), and the first peripheral area NAA1 may correspond to the peripheral area NAA (see Figure 5B ).

[0095] The signal lines GL, DL, and PL may include scan lines GL, data lines DL, and power lines PL. The scan lines GL transmit scan signals to the pixels PX. The pixels PX may be turned on / off in response to the scan signals. The data lines DL transmit data signals to the pixels PX. The pixels PX may display images corresponding to the data signals. The power lines PL transmit power signals (hereinafter, referred to as first power signals) to the pixels PX. However, this is merely an example. For example, in addition to the scan lines GL, the data lines DL, and the power lines PL, the signal lines GL, DL, and PL may also include other signal lines that are additionally connected to the pixels PX. Likewise, the exemplary embodiments are not limited to the specific configurations of the signal lines.

[0096] The pixel PX may be provided in plurality and arranged on the first area AA1. A signal circuit diagram of one pixel PX among the plurality of pixels is shown as an example. The pixel PX may include a first thin film transistor TR1, a capacitor CP, a second thin film transistor TR2, and a light emitting element EE.

[0097] The first thin film transistor TR1 may be a switching device that controls on / off of the pixel PX. The first thin film transistor TR1 may transmit or block a data signal transmitted through the data line DL in response to a scan signal transmitted through the scan line GL.

[0098] The capacitor CP is connected to the first thin film transistor TR1 and the power line PL. The capacitor CP charges an amount of electric charge corresponding to a difference between a data signal received from the first thin film transistor TR1 and a first power signal applied to the power line PL.

[0099] The second thin film transistor TR2 is connected to the first thin film transistor TR1, the capacitor CP and the light emitting element EE. The second thin film transistor TR2 controls the driving current flowing through the light emitting element EE to correspond to the amount of charge stored in the capacitor CP. The on time of the second thin film transistor TR2 can be determined according to the amount of charge charged in the capacitor CP. The second thin film transistor TR2 provides the first power signal transmitted through the power line PL to the light emitting element EE during the on time.

[0100] The light emitting element EE can generate light or control the amount of light according to the electrical signal. For example, the light emitting element EE can include an organic light emitting element, a quantum dot light emitting element, an electrophoresis element, or an electrowetting element.

[0101] The light emitting element EE may be connected to the power supply terminal VSS to receive a power signal (hereinafter, referred to as a second power signal) different from the first power signal provided by the power line PL. A driving current corresponding to the difference between the electric signal provided from the second thin film transistor TR2 and the second power signal may flow through the light emitting element EE, and the light emitting element EE may generate light corresponding to the driving current. However, this is only an example. For example, the pixel PX may include electronic components having various configurations and arrangements, and likewise, the exemplary embodiments are not limited to the specific configuration of the pixel PX.

[0102] The power pattern VDD is disposed in the first peripheral area NAA1. In an exemplary embodiment, the power pattern VDD is connected to the plurality of power lines PL. Therefore, the display panel unit DPU may include the power pattern VDD to provide the same first power signal to the plurality of pixels PX.

[0103] The display panel pad DPD is disposed on the first peripheral area NAA1. As described above, the first circuit board CB1 (see Figure 5B ) is electrically connected to the display panel unit DPU through the display panel pad DPD. The display panel pad DPD may be connected to one of the signal lines connected to the pixel PX. For example, the display panel pad DPD may include a first pad PDD1 connected to the data line DL and a second pad PDD2 connected to the power pattern VDD. However, this is only an example. For example, the display panel pad DPD may also include a pad connected to the scan line GL and / or a pad connected to other signal lines (not shown). Likewise, exemplary embodiments are not limited to the specific configuration and connection of the display panel pad DPD.

[0104] Reference Figure 6B, the input sensing unit ISU is disposed on the base substrate BS. The input sensing unit ISU may be disposed on the display panel unit DPU, disposed between the display panel unit DPU and the base substrate BS, or spaced apart from the display panel unit DPU and the base substrate BS disposed between the display panel unit DPU and the input sensing unit ISU. In an exemplary embodiment, the base substrate BS may correspond to the upper insulating layer TFL (see, for example, Figure 3A ).

[0105] The input sensing unit ISU includes a plurality of first electrodes TE1 , a plurality of second electrodes TE2 , a plurality of third electrodes GE, a plurality of signal lines TL11 , TL12 , TL21 , TL22 , and TL3 , and a plurality of input sensing pads TPD1 and TPD2 .

[0106] The first, second, and third electrodes TE1, TE2, and GE are disposed in a first area AA2 of the front surface IS2 of the input sensing unit ISU. The first area AA2 may overlap the first area AA1 of the display panel unit DPU and correspond to the active area AA of the electronic panel EP.

[0107] Signal lines TL11, TL12, TL21, TL22, and TL3 and input sensing pads TPD1 and TPD2 are disposed on a second area NAA2 of the front surface IS2. The second area NAA2 may overlap the first peripheral area NAA1 of the display panel unit DPU and correspond to the peripheral area NAA of the electronic panel EP.

[0108] The signal lines TL11, TL12, TL21, TL22, and TL3 may include a plurality of first sensing lines TL11 and TL12, a plurality of second sensing lines TL21, TL22, and a third sensing line TL3. The input sensing pads TPD1 and TPD2 may correspond to Figure 5B The input sensing pads TPD1 and TPD2 may include a first sensing pad group (also referred to as input sensing pads) TPD1 and a second sensing pad group (also referred to as input sensing pads) TPD2 disposed in separate areas.

[0109] The first electrodes TE1 are arranged in the first direction DR1 (eg, spaced apart from each other in the first direction DR1). Each of the first electrodes TE1 extends in the second direction DR2. Each of the first electrodes TE1 may include a plurality of first sensing patterns SP1 and a plurality of first connection patterns BP1.

[0110] Each of the first sensing patterns SP1 and the first connection patterns BP1 may be arranged in the second direction DR2. Each of the first connection patterns BP1 is disposed between adjacent ones of the first sensing patterns SP1. The first sensing patterns SP1 are electrically connected through the first connection patterns BP1.

[0111] The first sensing lines TL1 are respectively connected to the first electrodes TE1. The first sensing lines TL1 respectively connect the first electrodes TE1 to some of the input sensing pads TPD corresponding to the first electrodes TE1 among the first pads T11 and T12.

[0112] In an exemplary embodiment, the first sensing line TL1 may include a first lower sub-line TL11 and a second lower sub-line TL12. The first lower sub-line TL11 connects a portion of the first electrode TE1 to the first pad T11 of the first pads T11 and T12, and the second lower sub-line TL12 connects the remaining portion of the first electrode TE1 to the first pad T12 of the first pads T11 and T12.

[0113] The first sensing line TL1 may transmit an electrical signal provided through the first pads T11 and T12 to the first electrode TE1, or may transmit an electrical signal provided from the first electrode TE1 to the outside through the first pads T11 and T12. However, this is only an example. For example, the first pads T11 and T12 may be continuously arranged on one side of the display panel pad DPD, and likewise, the exemplary embodiment is not limited to the specific configuration of the first pads T11 and T12.

[0114] The second electrodes TE2 are arranged in the second direction DR2 (eg, spaced apart from each other in the second direction DR2). Each second electrode TE2 extends in the first direction DR1. Each second electrode TE2 may include a plurality of second sensing patterns SP2 and a plurality of second connection patterns BP2.

[0115] The second sensing patterns SP2 and the second connection patterns BP2 may be arranged in the first direction DR1. Each second connection pattern BP2 is disposed between adjacent ones of the second sensing patterns SP2. The second sensing patterns SP2 are electrically connected through the second connection patterns BP2.

[0116] The second sensing lines TL21 and TL22 are respectively connected to the second electrode TE2. The second sensing lines TL21 and TL22 connect the second electrode TE2 to the second pads T21 and T22. The second sensing lines TL21 and TL22 may include a first sub-line TL21 and a second sub-line TL22.

[0117] The first sub-line TL21 may be disposed at the left side of the first area AA2 and connected to a portion of the second electrode TE2. Each first sub-line TL21 may be connected to one side of a portion of the second electrode TE2. In an exemplary embodiment, each first sub-line TL21 may be connected to one side of each second electrode TE2 disposed in the odd-numbered rows of the second electrodes TE2.

[0118] The second sub-line TL22 may be disposed at the right side of the first area AA2 and connected to another portion of the second electrode TE2. The second sub-line TL22 is connected to the other side of the remaining electrode of the second electrode TE2. In an exemplary embodiment, each second sub-line TL22 may be connected to the other side of each of the second electrodes TE2 arranged in the even-numbered rows. The other side may be opposite to the one side in the first direction DR1.

[0119] The second electrode TE2 connected to the second sub-line TL22 may be an electrode not connected to the first sub-line TL21. That is, in an exemplary embodiment, each second electrode TE2 may be selectively connected to one line of the first sub-line TL21 and the second sub-line TL22.

[0120] The second sensing line TL2 may transmit an electrical signal provided through the second pads T21 and T22 to the second electrode TE2 , or may transmit an electrical signal provided from the second electrode TE2 to the outside through the second pads T21 and T22 .

[0121] The second electrode TE2 may receive an electrical signal different from the electrical signal applied to the first electrode TE1. Here, the second electrode TE2 may generate an electric field together with the first electrode TE1. The input sensing unit ISU may sense the external input TC by a change in capacitance formed between the second electrode TE2 and the first electrode TE1 (see, for example, Figure 4 ).

[0122] Alternatively, the second electrode TE2 may receive the same electrical signal as that of the first electrode TE1. Here, the input sensing unit ISU may sense the external input TC by a change in capacitance generated in each of the second electrode TE2 and the first electrode TE1 due to the external input TC (see, for example, Figure 4 ).

[0123] The third electrodes GE are arranged in the second direction DR2 (eg, spaced apart from each other in the second direction DR2 ). Each of the third electrodes GE extends in the first direction DR1 . Each of the third electrodes GE may include a plurality of conductive patterns GP and a plurality of conductive connection patterns GBP.

[0124] The conductive patterns GP and the conductive connection patterns GBP are arranged in the first direction DR1. The conductive connection patterns GBP are respectively disposed between adjacent conductive patterns GP among the conductive patterns GP and overlap the first electrodes TE1. However, this is only an example. For example, the third electrodes GE may be arranged in the first direction DR1, but exemplary embodiments are not limited thereto.

[0125] In a plan view, the third electrode GE may be spaced apart from the second electrode TE2. Each of the conductive patterns GP may be surrounded by a corresponding second sensing pattern SP2 in the second sensing patterns SP2, respectively. For example, the conductive patterns GP may be respectively disposed in openings defined in the second sensing patterns SP2. The conductive connection pattern GBP may be disposed so that the conductive connection pattern GBP does not overlap with the second connection pattern BP2 in a plan view. This will be described in more detail later. However, this is merely an example. For example, each of the first electrode TE1, the second electrode TE2, and the third electrode GE may have various shapes, but exemplary embodiments are not limited thereto.

[0126] The third sensing line TL3 is connected to the third electrode GE. The third sensing line TL3 connects the third pads T31 and T32 to the third electrode GE. The third pads T31 and T32 may be spaced apart from each other and disposed on both sides of the display panel pad DPD, respectively, but exemplary embodiments are not limited thereto.

[0127] In an exemplary embodiment, the third sensing line TL3 may be provided as a single integrated body. Thus, a plurality of third electrodes GE may be connected to each other through the single integrated third sensing line TL3. However, this is merely an example. For example, the third sensing line TL3 may be provided as a plurality of third sensing lines TL3 that transmit the same electrical signal and are respectively connected to corresponding pads of the input sensing pad TPD. The third sensing line TL3 according to the exemplary embodiment may have various shapes, and likewise, the exemplary embodiment is not limited to the specific configuration of the third sensing line TL3.

[0128] According to an exemplary embodiment, the third sensing line TL3 is connected to one side of a portion of the third electrodes GE among the third electrodes GE, and is also connected to the other side of the remaining electrodes among the third electrodes GE. For example, the third sensing line TL3 may be connected to a portion of the third electrodes GE among the third electrodes GE at the left side of the first area AA2, and to the remaining electrodes among the third electrodes GE at the right side of the first area AA2. This will be described in more detail later.

[0129] The third sensing line TL3 may transmit an electrical signal provided through the third pads T31 and T32 to the third electrode GE. In an exemplary embodiment, the third sensing line TL3 may transmit an electrical signal different from an electrical signal transmitted by each of the first and second sensing lines TL1 and TL2.

[0130] For example, in an exemplary embodiment, the third sensing line TL3 may receive a ground voltage. Therefore, the third electrode GE may maintain a ground voltage. The third electrode GE may prevent parasitic capacitance from being generated between an electrical component provided in the display panel unit DPU and the first electrode TE1 or the second electrode TE2. Therefore, even if the input sensing unit ISU and the display panel unit DPU constitute one electronic panel EP, the occurrence of noise in the input sensing unit ISU due to the display panel unit DPU may be stably prevented (or at least reduced) to improve the electrical reliability and sensitivity of the input sensing unit ISU.

[0131] The input sensing unit ISU according to an exemplary embodiment may include a plurality of row electrodes CLE sequentially arranged in a direction opposite to the second direction DR2. Each of the row electrodes CLE may be defined by a second electrode TE2 and a third electrode GE. For example, one row electrode CLE may be composed of one second electrode TE2 extending in the first direction DR1 and a third electrode GE including a conductive pattern GP surrounded by a second sensing pattern SP2.

[0132] According to an exemplary embodiment, in one row electrode CLE, one side and the other side opposite to each other in the first direction DR1 may be connected to different sensing lines from each other. For example, one side of one row electrode CLE may be connected to one of the second sensing lines TL21 and TL22 and the third sensing line TL3, and the other side may be connected to the other of the second sensing lines TL21 and TL22 and the third sensing line TL3.

[0133] For example, when one of the second sensing lines TL21 and TL22 is connected to the left side of the second electrode TE2 of one row electrode CLE, the third sensing line TL3 may be connected to the right side of the third electrode GE of the same row electrode CLE. Here, the sensing line may not be connected to the right side of the second electrode TE2 and the left side of the third electrode GE. Alternatively, when one of the second sensing lines TL21 and TL22 is connected to the right side of the second electrode TE2 of one row electrode CLE, the third sensing line TL3 may be connected to the left side of the third electrode GE of the same row electrode CLE. Here, the sensing line may not be connected to the left side of the second electrode TE2 and the right side of the third electrode GE.

[0134] like Figure 6CAs shown in , in the input sensing unit ISU_P, each of the third sensing line TL3P and the third pad T3P may be set to a plurality. The plurality of third sensing lines TL3P and the plurality of third pads T3P may be respectively connected to the corresponding third electrodes GE. As described above, the plurality of third sensing lines TL3P and the second sensing lines TL21 and TL22 may be alternately connected to the side of the row electrode CLE. Here, the third electrode GE may receive an electrical signal for sensing noise in the active area AA to sense whether noise occurs due to the position. According to exemplary embodiments, the input sensing unit ISU_P may be designed to have various structures, and likewise, the exemplary embodiments are not limited to the specific configuration of the input sensing unit ISU_P.

[0135] Fig. 7A and Figure 7B is a plan view of an input sensing unit according to various exemplary embodiments. For example, Fig. 7A and Figure 7B Schematic plan views of input sensing units ISU_N and ISU_H according to various exemplary embodiments are shown. As described above, although each of the first sub-line TL11, the second lower sub-line TL12, the first sub-line TL21, and the second sub-line TL22 includes a plurality of lines divided into lines connected to the corresponding pads T11, T12, T21, and T22, respectively, for ease of description, each of the first sub-line TL11, the second lower sub-line TL12, the first sub-line TL21, the second sub-line TL22, and the corresponding pads T11, T12, T21, and T22 is shown as a single grouped line or pad. Hereinafter, the present disclosure will be described with reference to the accompanying drawings.

[0136] like Fig. 7A and Figure 7B As shown in FIG. 1 , the input sensing units ISU_N and ISU_H may have various shapes. Fig. 7A , the input sensing unit ISU_N may include a predetermined notch portion NT. The notch portion NT may be defined in the base substrate BS or the display panel unit DPU (see Fig. 6A In an exemplary embodiment, the notch portion NT may be defined by recessing a portion of the upper side of the base substrate BS extending in the first direction DR1 in an opposite direction of the second direction DR2.

[0137] Since the notch portion NT is defined, a portion of the first electrode TE1 and a portion of the third electrode GE may be Figure 6B The input sensing unit ISU is removed. At least one of the row electrodes CLE may extend through the notch portion NT. In an exemplary embodiment, the row electrode CLE disposed at the uppermost side may pass through the notch portion NT.

[0138] For example, due to the notch portion NT, a portion of the first electrode TE1 may have a surface area or length smaller than that of the first electrode TE1 of a region spaced apart from the notch portion NT. The first electrode TE1 spaced apart from the notch portion NT in the second direction DR2 may have a length and a surface area smaller than those of the remaining first electrode TE1 spaced apart from the notch portion NT in the first direction DR1.

[0139] In addition, for example, a portion of the second electrode TE2 may be divided into a left portion and a right portion relative to the notch portion NT. The second connection pattern element BP2N that connects the second sensing pattern SP2 of the second electrode TE2 adjacent to the left side of the notch portion NT and the second sensing pattern SP2 adjacent to the right side of the notch portion NT may extend along the edge of the notch portion NT. Therefore, even if some of the second electrodes TE2 are divided by the notch portion NT, a portion of the second electrode TE2 may be electrically connected through the second connection pattern element BP2N.

[0140] In addition, for example, a portion of the third electrode GE may be divided into a left portion and a right portion with respect to the notch portion NT, like the second electrode TE2. Therefore, the conductive connection pattern GBPN adjacent to the notch portion NT may extend along the edge of the notch portion NT to connect two conductive patterns GP, which are spaced apart from each other in the first direction DR1 and have the notch portion NT therebetween, to each other. Therefore, even if some of the third electrodes GE are separated by the notch portion NT, a portion of the third electrodes GE may be electrically connected through the conductive connection pattern GBPN.

[0141] like Figure 7B As shown in FIG. 1 , the input sensing unit ISU_M may include a predetermined hole MH. The hole MH is defined in the first area AA2 to at least pass through the input sensing unit ISU_H. In an exemplary embodiment, the hole MH may pass through the input sensing unit ISU_H and the base substrate BS. The electronic module EM1 (see FIG. 1 ) Figure 5A ) (such as a camera module CMM (see Figure 5A ) or optical receiver module LRM (see Figure 5A )) can be arranged to overlap with hole MH.

[0142] At least a portion of the first electrode TE1, the second electrode TE2, and the third electrode GE may have a shape from which a portion adjacent to the hole MH is removed. In an exemplary embodiment, the hole MH may be defined between two row electrodes CLE sequentially arranged from the outermost electrodes of the row electrodes CLE.

[0143] According to an exemplary embodiment, the hole MH is adjacent to the two first sensing patterns SP1, the two second sensing patterns SP2, and the two conductive patterns GP. Each of the two first sensing patterns SP1, the two second sensing patterns SP2, and the two conductive patterns GP adjacent to the hole MH may have a relatively small surface area when compared with the corresponding peripheral patterns. Sides of the two first sensing patterns SP1, the two second sensing patterns SP2, and the two conductive patterns GP facing the hole MH may have a curved shape extending along the edge of the hole MH.

[0144] According to various exemplary embodiments, input sensing units ISU, ISU_P, ISU_N, and ISU_H having various shapes may be provided. In addition, the input sensing units ISU, ISU_P, ISU_N, and ISU_H having various shapes may have a structure in which the second sensing lines TL21 and TL22 and the third sensing line TL3 are connected at different positions with respect to a single row electrode CLE, respectively. Therefore, an electronic device EA is provided in which the third sensing line TL3 is prevented from overlapping with the second sensing lines TL21 and TL22 in a top view, and this can improve the electrical reliability of the electronic device EA.

[0145] Fig. 8A and Figure 8B is a diagram showing various exemplary embodiments Figure 6B , Figure 6C , Fig. 7A and Figure 7B A plan view of a portion of the area of ​​each of the input sensing units. For ease of description, Fig. 8A Shows Figure 6B The right area of ​​the four row electrodes CLE1, CLE2, CLE3 and CLE4 of the input sensing unit ISU, Figure 8B In addition, the left area is shown in Fig. 7A and Figure 7B The parts L11, L12 and L1N of the plurality of first sub-lines TL21 are described. Figures 1 to 7B The components are the same as those of FIG. 1 , and their detailed description will be mainly omitted.

Fig. 8A , the right end GP1R of the third electrode GE of the first row electrode CLE1 is connected to the third sensing line TL3. On the other hand, the right end SP21R of the second electrode TE2 of the first row electrode CLE1 is not connected to the second sub-line TL22. The right end SP21R of the second electrode TE2 of the first row electrode CLE1 is spaced apart from the second sub-line TL22 and the third sensing line TL3. Therefore, the third sensing line TL3 can be stably connected to the third electrode GE without overlapping the second sub-line TL22 or the second electrode TE2.

[0148] Reference Figure 8B , the left end SP21L of the second electrode TE2 of the first row electrode CLE1 is connected to one line of the first sub-line TL21. Here, the electronic device EA may further include a connection portion CP11 connecting the second electrode TE2 of the first row electrode CLE1 to the one line L11 of the first sub-line TL21. The left end SP21L of the second electrode TE2 of the first row electrode CLE1 and the line L11 may be connected to the connection portion CP11, and then electrically connected to each other through a contact portion CTS between the connection portion CP11 and the second electrode TE2 of the first row electrode CLE1 and a contact portion CTL between the connection portion CP11 and the one line L11 of the first sub-line TL21. Therefore, the second electrode TE2 of the first row electrode CLE1 may be stably connected to the one line L11 of the first sub-line TL21 without contacting the third sensing line TL3.

[0149] On the other hand, the left end GP1L of the third electrode GE of the first row electrode CLE1 is not connected to the third sensing line TL3. The left end GP1L of the third electrode GE of the first row electrode CLE1 is spaced apart from the first sub-line TL21 and the third sensing line TL3.

Therefore, the overlap between the third sensing line TL3 and the second electrode TE2 may be reduced. In an exemplary embodiment, the interference between the third sensing line TL3 and the line L11 may be prevented to improve the electrical reliability of the electronic device EA.

One side of each of the second to fourth row electrodes CLE2, CLE3, and CLE4 may be selectively connected to one of the second sensing lines TL21 and TL22 and the third sensing line TL3.

The left end GP2L of the third electrode GE of the second row electrode CLE2 may be connected to the third sensing line TL3, and the left end SP22L of the second electrode TE2 of the second row electrode CLE2 may not be connected to the second sensing lines TL21 and TL22. On the other hand, the right end SP22R of the second electrode TE2 of the second row electrode CLE2 may be connected to one line L21 of the second sensing lines TL21 and TL22, and the right end GP2R of the third electrode GE of the second row electrode CLE2 may not be connected to the third sensing line TL3 and may be spaced apart from the third sensing line TL3.

[0153] In an exemplary embodiment, the third row electrode CLE3 may have a connection structure corresponding to that of the first row electrode CLE1. For example, the left end SP23L of the third row electrode CLE3 may be connected to one line L12 of the second sensing lines TL21 and TL22, and the right end GP3R of the third row electrode CLE3 may be connected to the third sensing line TL3. That is, the left end SP23L of the second electrode TE2 of the third row electrode CLE3 may be connected to one line L12 of the second sensing lines TL21 and TL22, and the right end GP3R of the third electrode GE of the third row electrode CLE3 may be connected to the third sensing line TL3. The right end SP23R of the second electrode TE2 of the third row electrode CLE3 and the left end GP3L of the third electrode GE of the third row electrode CLE3 are not connected to the second sensing lines TL21 and TL22 and the third sensing line TL3.

[0154] The fourth row electrode CLE4 may have a connection structure corresponding to the connection structure of the second row electrode CLE2. For example, the left end GP4L of the fourth row electrode CLE4 may be connected to the third sensing line TL3, and the right end SP24R of the fourth row electrode CLE4 may be connected to one line L22 of the second sensing lines TL21 and TL22. That is, the left end GP4L of the third electrode GE of the fourth row electrode CLE4 may be connected to the third sensing line TL3, and the left end SP24L of the second electrode TE2 of the fourth row electrode CLE4 may not be connected to the second sensing lines TL21 and TL22. On the other hand, the right end SP24R of the second electrode TE2 of the fourth row electrode CLE4 may be connected to one line L22 of the second sensing lines TL21 and TL22, and the right end GP4R of the third electrode GE of the fourth row electrode CLE4 may not be connected to the third sensing line TL3.

[0155] According to various exemplary embodiments, the second electrode TE2 and the third electrode GE constituting the same row electrode CLE may be connected to corresponding lines of the second sensing lines TL21 and TL22 and the third sensing line TL3 at different positions, respectively. Therefore, the connection between the second electrode TE2 and the second sensing lines TL21 and TL22 and the connection between the third electrode GE and the third sensing line TL3 may be designed not to overlap each other in a plan view.

[0156] In addition, according to various exemplary embodiments, overlap between the third sensing line TL3 and other sensing lines TL11, TL12, TL21, and TL22, or overlap between the third electrode GE and other sensing lines TL11, TL12, TL21, and TL22 may be reduced or prevented. Thus, malfunctions (such as in the case of an input sensing unit (e.g., Figure 6B The occurrence of noise generated between different signal lines in the input sensing unit ISU) can be reduced, and in this way, the electrical reliability of the electronic device EA can be improved.

[0163] Reference Fig. 9B, the right end SP22R of the second electrode TE2 of the second row electrode CLE2 is connected to the corresponding line L21 of the second sensing line TL22. Here, the line L21 corresponding to the second row electrode CLE2 may be electrically connected by a connection portion CP12 disposed on a different layer from the second electrode TE2. In an exemplary embodiment, the connection portion CP12 may be disposed on the same layer as the first connection pattern BP1 or the conductive connection pattern GBP. The line L21 corresponding to the right end SP22R of the second electrode TE2 of the second row electrode CLE2 may be connected to the connection portion CP12 through the insulating layer SIL, and thus may be stably connected to the line L21 without being electrically connected to the third sensing line TL3. However, this is merely an example. For example, the connection portion CP12 may be disposed above the third sensing line TL3 and overlap the third sensing line TL3, but exemplary embodiments are not limited thereto.

The first grid line MSL1 and the second grid line MSL2 form a first sensing pattern SP1_M, a second sensing pattern SP2_M, a second connection pattern BP2_M, and a conductive pattern GP_M. The boundaries between the first sensing pattern SP1_M, the second sensing pattern SP2_M, the second connection pattern BP2_M, and the conductive pattern GP_M may be formed by cutting the first grid line MSL1 and the second grid line MSL2.

In addition, when the second electrode TE2_M and the third electrode GE_M are arranged in the same row, the second electrode TE2_M and the third electrode GE_M may be spaced apart from each other in a plan view. Therefore, electrical connection between the second electrode TE2_M and the third electrode GE_M that independently transmit signals may be prevented, and thus the electrical reliability of the electronic device EA_M may be improved.

Fig. 12A As shown in , in the first row electrode CLE_M1, the right end of the third electrode GE_M1 may extend further in the first direction DR1 than the right end of the second electrode TE2_M1.

Therefore, the right end of the third electrode GE_M1 may be directly connected to the third sensing line TL3. However, this is only an example. For example, the right end of the third electrode GE_M1 may be integrated with the third sensing line TL3, but the exemplary embodiment is not limited thereto.

[0181] Fig. 12B FIG. 4 shows a portion of the right end region of the second row electrode CLE_M2. Fig. 12B As shown in FIG. 2 , in the second row electrode CLE_M2 , the right end of the second electrode TE2_M2 may extend farther in the first direction DR1 than the right end of the third electrode GE_M2 .

The second electrode TE2_M2 may be connected to the connection portion CP_M through a predetermined contact portion CTS. The second sensing line TL2 may be connected to the connection portion CP_M through a predetermined contact portion CTL. Therefore, the second electrode TE2_M may be stably connected to the second sensing line TL2 without overlapping the third sensing line TL3.

[0183] According to various exemplary embodiments, overlap between signal lines that transmit different electrical signals can be reduced or prevented. Therefore, the occurrence of noise due to electrical interference between signal lines can be reduced (or prevented) to improve the input sensing unit to have improved external input sensitivity. In addition, a display device with improved electrical reliability can be provided.
