Description

Technical Field

[0001] Aspects of embodiments of the present disclosure relate to an electronic device for sensing an input through a pen and a proximity input through a pen. Background Art

[0002] Multimedia electronic devices such as televisions, mobile phones, tablet computers, laptops, car navigation units, and game consoles include display devices for displaying images. In addition to conventional input methods such as buttons, keyboards, and mice, these electronic devices may include a sensor layer (e.g., input sensor) capable of providing a touch-based input method. This touch-based input method allows users to intuitively and conveniently input information or instructions in a simple and easy manner. The sensor layer can sense the user's touch or pressure. Furthermore, users are increasingly being accustomed to using writing instruments or pens to input information, enabling precise touch input in specific applications (e.g., drawing or painting applications).

[0065] Hereinafter, embodiments will be described in more detail with reference to the accompanying drawings, in which the same reference numerals represent the same elements throughout. However, the present disclosure can be implemented in various different forms and should not be construed as being limited to the embodiments described herein. On the contrary, these embodiments are provided as examples so that the present disclosure will be thorough and complete, and will fully convey the aspects and features of the present disclosure to those skilled in the art. Therefore, unnecessary processes, elements and techniques for fully understanding the aspects and features of the present disclosure for those of ordinary skill in the art may not be described. Unless otherwise stated, throughout the drawings and written description, the same reference numerals represent the same elements, and therefore, their redundant descriptions may not be repeated.

[0066] When a specific embodiment can be implemented differently, the specific process order can be different from the described order. For example, two consecutively described processes can be performed simultaneously or substantially simultaneously, or can be performed in the reverse order of the described order.

[0067] In addition, as will be understood by those skilled in the art, considering the overall content of the present disclosure, each suitable feature of the various embodiments of the present disclosure may be combined or partially or completely combined with each other, and may be technically interconnected and operated in various suitable manners, and each embodiment may be implemented independently of each other or in combination with each other in any suitable manner, unless otherwise stated or implied.

[0068] In the accompanying drawings, the relative sizes, thicknesses, and proportions of elements, layers, and regions may be exaggerated and / or simplified for clarity. For ease of explanation, spatially relative terms such as "below," "beneath," "below," "beneath," "above," and "on" may be used herein to describe the relationship between an element or feature and another element or feature as shown in the figures. It will be understood that, in addition to the orientation depicted in the figures, spatially relative terms are intended to include different orientations of the device in use or in operation. For example, if the device in the figure is flipped, an element described as being "below," "below," or "below" another element or feature will then be oriented "above" the other element or feature. Therefore, the exemplary terms "below" and "below" may include both above and below orientations. The device may be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein should be interpreted accordingly.

[0069] Furthermore, it is contemplated that, in practice, the shapes shown in the figures may vary depending on, for example, tolerances and / or manufacturing techniques. Accordingly, embodiments of the present disclosure should not be construed as limited to the specific shapes shown in the figures and should be interpreted in light of changes in shape that may occur, for example, due to manufacturing. Thus, the shapes shown in the figures may not depict the actual shape of regions of the device, and the present disclosure is not limited thereto.

[0070] In the drawings, the DR1, DR2, and DR3 axes are not limited to the three axes of the rectangular coordinate system and can be interpreted in a broader sense. For example, the DR1, DR2, and DR3 axes may be perpendicular or substantially perpendicular to each other, or may represent different directions that are not perpendicular to each other.

[0071] It will be understood that although the terms "first," "second," "third," etc. may be used herein to describe various elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms are used to distinguish one element, component, region, layer, or section from another element, component, region, layer, or section. Thus, a first element, first component, first region, first layer, or first section described below may be referred to as a second element, second component, second region, second layer, or second section without departing from the spirit and scope of the present disclosure.

[0072] It will be understood that when an element or layer is referred to as being "on," "connected to," or "coupled to" another element or layer, it can be directly on, directly connected to, or directly coupled to the other element or layer, or one or more intervening elements or layers may be present. Similarly, when a layer, region, or element is referred to as being "electrically connected to" another layer, region, or element, it can be directly electrically connected to the other layer, region, or element, and / or can be indirectly electrically connected to the other layer, region, or element with one or more intervening layers, regions, or elements therebetween. Furthermore, it will be understood that when an element or layer is referred to as being "between" two elements or layers, it can be the only element or layer between the two elements or layers, or one or more intervening elements or layers may also be present.

[0073] The terms used herein are for the purpose of describing specific embodiments and are not intended to limit the present disclosure. As used herein, the singular forms "a" and "an" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that, when used in this specification, the terms "comprises," "comprising," "includes," "incluiding," "has," "have," and "having" specify the presence of the stated features, wholes, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or groups thereof. As used herein, the term "and / or" includes any and all combinations of one or more of the relevant listed items. For example, the expression "A and / or B" means A, B, or A and B. When located after an element of a list, expressions such as "at least one of..." modify the elements of the entire list without modifying the individual elements in the list. For example, the expressions "at least one of a, b, and c" and "at least one selected from the group consisting of a, b, and c" mean only a, only b, only c, both a and b, both a and c, both b and c, all of a, b, and c, or variations thereof.

[0074] As used herein, the terms "substantially," "about," and similar terms are used as terms of approximation, not as terms of degree, and are intended to allow for the inherent deviations in measurements or calculations that will be recognized by one of ordinary skill in the art. In addition, when describing embodiments of the present disclosure, the use of "may" refers to "one or more embodiments of the present disclosure." As used herein, the terms "use," "using," and "used" may be understood as synonymous with the terms "utilize," "utilizing," and "utilized," respectively.

[0075] 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 the present disclosure belongs. It will also be understood that 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 / or this specification, and should not be interpreted in an idealized or overly formal sense unless explicitly defined as such herein.

[0076] Figure 1A is a perspective view of an electronic device 1000 according to an embodiment of the present disclosure. Figure 1B is a rear perspective view of the electronic device 1000 according to an embodiment of the present disclosure.

[0077] refer to Figure 1A and Figure 1B The electronic device 1000 may be a device activated by an electrical signal. For example, the electronic device 1000 may display an image and may sense an input applied from the outside (e.g., an external input). The external input may be a user input. The user input may include various suitable types of external inputs, such as a part of the user's body, a pen, light, heat, or pressure.

[0078] The electronic device 1000 may include a first display panel DP1 and a second display panel DP2. The first display panel DP1 and the second display panel DP2 may be separate panels that are spaced apart (e.g., separated) from each other. The first display panel DP1 may be referred to as a main display panel, and the second display panel DP2 may be referred to as an auxiliary display panel or an external display panel.

[0079] The first display panel DP1 may include a first display portion DA1-F, and the second display panel DP2 may include a second display portion DA2-F. The area of the second display panel DP2 may be smaller than that of the first display panel DP1. The area of the first display portion DA1-F may be larger than that of the second display portion DA2-F to correspond to the sizes of the first display panel DP1 and the second display panel DP2.

[0080] When the electronic device 1000 is in the unfolded state, the first display portion DA1-F may have a plane that is parallel or substantially parallel to the first direction DR1 and the second direction DR2. The thickness direction of the electronic device 1000 may be parallel or substantially parallel to a third direction DR3 that intersects the first direction DR1 and the second direction DR2. Therefore, the front surface (e.g., the upper surface) and the rear surface (e.g., the lower surface) of the components constituting the electronic device 1000 may be defined based on the third direction DR3.

[0081] The first display panel DP1 or the first display portion DA1-F may include a foldable and unfoldable folding area FA and a plurality of non-folding areas NFA1 and NFA2 spaced apart from each other with the folding area FA therebetween. The second display panel DP2 may overlap one of the plurality of non-folding areas NFA1 and NFA2. For example, the second display panel DP2 may overlap the first non-folding area NFA1.

[0082] The display direction of the first image IM1a displayed on a portion of the first display panel DP1 (e.g., such as displayed on the second non-folding area NFA2) may be opposite to the display direction of the second image IM2a displayed on the second display panel DP2. For example, the first image IM1a may be displayed in a third direction DR3, and the second image IM2a may be displayed in a fourth direction DR4 opposite to the third direction DR3.

[0083] In embodiments of the present disclosure, the folding area FA can be curved about a folding axis that extends parallel to or substantially parallel to the long sides of the electronic device 1000, such as, for example, extending parallel to or substantially parallel to the second direction DR2. When the electronic device 1000 is folded, the folding area FA can have a curvature (e.g., a specific or predetermined curvature) and a curvature radius (e.g., a specific or predetermined curvature radius). The electronic device 1000 can be folded inwardly, such that the first non-folding area NFA1 and the second non-folding area NFA2 face each other, and the first display portion DA1-F is not exposed to the outside.

[0084] In an embodiment of the present disclosure, the electronic device 1000 can be folded in an outward folding manner so that the first display portion DA1-F is exposed to the outside. In an embodiment of the present disclosure, the electronic device 1000 can be folded in an inward folding manner and an outward folding manner from an unfolded state. However, the present disclosure is not limited thereto.

[0085] although Figure 1A An example is shown in which one folding area FA is defined in the electronic device 1000, but the present disclosure is not limited thereto. For example, multiple folding axes and multiple folding areas FA corresponding to the folding axes may be defined in the electronic device 1000. In this case, the electronic device 1000 can be folded from the unfolded state in an inward folding manner and / or an outward folding manner around the multiple folding axes.

[0086] According to an embodiment of the present disclosure, even without including or using a digitizer, at least one of the first display panel DP1 and the second display panel DP2 can sense input from the pen PN. Because the digitizer for sensing the pen PN can be omitted, the increase in thickness and weight of the electronic device 1000 and the decrease in flexibility of the electronic device 1000 caused by the addition of the digitizer can be avoided. Therefore, in some embodiments, one or both of the first display panel DP1 and the second display panel DP2 can be designed to sense the pen PN.

[0087] Figure 2 is a perspective view of an electronic device 1000 - 1 according to an embodiment of the present disclosure. Figure 3 is a perspective view of an electronic device 1000 - 2 according to an embodiment of the present disclosure.

[0088] Figure 2 An example is shown in which the electronic device 1000 - 1 is a mobile phone, and the electronic device 1000 - 1 may include a display panel DP. Figure 3 An example is shown in which the electronic device 1000 - 2 is a notebook computer, and the electronic device 1000 - 2 may include a display panel DP.

[0089] In an embodiment of the present disclosure, the display panel DP may sense an input applied from the outside (eg, an external input). The external input may be a user input. The user input may include various appropriate types of external inputs, such as a part of the user's body, a pen PN (eg, a reference Figure 1A ), light, heat or pressure.

[0090] According to an embodiment of the present disclosure, the display panel DP can sense the input of the pen PN even without using or including a digitizer. Since the digitizer for sensing the pen PN can be omitted, the increase in thickness and weight of the electronic device 1000-1 or 1000-2 caused by adding a digitizer can be avoided.

[0091] Despite Figure 1A A foldable electronic device 1000 is shown in FIG. Figure 2 1 shows a bar-type electronic device 1000 - 1 , but the present disclosure is not limited thereto.

Furthermore, the embossed sheet may include an embossed pattern to prevent or substantially prevent bubbles from forming when the first lower layer CSL is attached to the protective film PFa. The cushion layer may protect the display panel DP from impacts transmitted from below. The cushion layer may improve the impact resistance of the electronic device 1000-1.

[0123] An opening F_OP may be defined in the first lower layer CSL, and a fingerprint sensor FOD may be disposed in the opening F_OP. The fingerprint sensor FOD may be attached to the protective film PFa. In an embodiment of the present disclosure, the fingerprint sensor FOD may be omitted as needed or desired.

[0124] The shielding layer MMPa may be disposed below the first lower layer CSL. The shielding layer MMPa may shield magnetic fields transmitted through the display panel DP.

[0130] Figure 6 is a schematic cross-sectional view of a display panel DP according to an embodiment of the present disclosure.

[0131] refer to Figure 6 , the display panel DP may include a display layer 100 and a sensor layer 200 .

[0132] The display layer 100 may be a component that generates or substantially generates an image. The display layer 100 may be an emissive display layer. For example, the display layer 100 may be an organic light-emitting display layer, an inorganic light-emitting display layer, an organic-inorganic light-emitting display layer, a quantum dot display layer, a micro-LED display layer, or a nano-LED display layer. The display layer 100 may include a base layer 110, a circuit layer 120, a light-emitting element layer 130, and an encapsulation layer 140.

[0133] The base layer 110 may be a member providing a base surface on which the circuit layer 120 is provided. The base layer 110 may have a multi-layer structure or a single-layer structure. The base layer 110 may be a glass substrate, a metal substrate, a silicon substrate, or a polymer substrate, but the present disclosure is not particularly limited thereto.

[0134] The circuit layer 120 may be provided on the base layer 110. The circuit layer 120 may include an insulating layer, a semiconductor pattern, a conductive pattern, and a signal line. The insulating layer, the semiconductor layer, and the conductive layer may be formed on the base layer 110 by appropriate processes such as coating or deposition, and may be selectively patterned by performing a photolithography process multiple times.

[0135] The light emitting element layer 130 may be provided on the circuit layer 120. The light emitting element layer 130 may include a light emitting element. For example, the light emitting element layer 130 may include an organic light emitting material, an inorganic light emitting material, an organic-inorganic light emitting material, a quantum dot, a quantum rod, a micro-LED, or a nano-LED.

[0136] The encapsulation layer 140 may be disposed on the light emitting element layer 130. The encapsulation layer 140 may protect the light emitting element layer 130 from moisture, oxygen, and foreign substances such as dust particles.

[0137] The sensor layer 200 may be provided on the display layer 100. The sensor layer 200 may sense external input applied from the outside. The sensor layer 200 may be an integrated sensor formed continuously during the process of manufacturing the display layer 100. As another example, the sensor layer 200 may be an external sensor attached to the display layer 100. The sensor layer 200 may be referred to as a sensor, an input sensing layer, an input sensing panel, or an electronic device for sensing input coordinates.

[0138] According to an embodiment of the present disclosure, the sensor layer 200 can sense both input through a passive input device (such as a part of the user's body) and input through an input device that generates a magnetic field with an appropriate resonant frequency (e.g., a specific or predetermined resonant frequency). The input device may be referred to as a pen, input pen, magnetic pen, stylus, or electromagnetic resonance pen.

[0139] Figure 7 is a view illustrating the operation of the electronic device 1000 according to an embodiment of the present disclosure.

[0140] refer to Figure 7 , the electronic device 1000 may include a display layer 100, a sensor layer 200, a display driver 100C, a sensor driver 200C, a main driver 1000C, and a power circuit 1000P.

[0141] Sensor layer 200 can sense a first input 2000 or a second input 3000 applied externally. Each of first input 2000 and second input 3000 can be an input capable of causing a change in capacitance of sensor layer 200 or an input capable of inducing an induced current in sensor layer 200. For example, first input 2000 can be a passive input, such as a part of a user's body. Second input 3000 can be an input via a pen PN or an input via an RFIC tag. For example, pen PN can be a passive pen or an active pen.

[0142] In embodiments of the present disclosure, a pen PN may be a device that generates a magnetic field having an appropriate resonant frequency (e.g., a specific or predetermined resonant frequency). The pen PN may transmit an output signal based on an appropriate electromagnetic resonance scheme. The pen PN may also be referred to as an input device, an input pen, a magnetic pen, a stylus, or an electromagnetic resonance pen.

[0143] The pen PN may include an RLC resonant circuit. The RLC resonant circuit may include an inductor L and a capacitor C. In an embodiment of the present disclosure, the RLC resonant circuit may be a variable resonant circuit that changes the resonant frequency. In this case, the inductor L may be a variable inductor, and / or the capacitor C may be a variable capacitor. However, the present disclosure is not particularly limited to this.

[0144] Inductor L generates current through the magnetic field formed in sensor layer 200. However, the present disclosure is not particularly limited to this. For example, when pen PN operates in an active mode, pen PN can generate current even without an external magnetic field. The generated current is transmitted to capacitor C. Capacitor C is charged with the current input from inductor L and discharges the charged current to inductor L. Thereafter, inductor L can emit a magnetic field having a resonant frequency. The magnetic field emitted from pen PN can cause an induced current to flow in sensor layer 200. The induced current can be transmitted to sensor driver 200C as a received signal (e.g., a sensing signal or a signal).

[0145] The main driver 1000C can control the overall operation of the electronic device 1000. For example, the main driver 1000C can control the operation of the display driver 100C and the sensor driver 200C. The main driver 1000C may include at least one microprocessor and may also include a graphics controller. The main driver 1000C may be referred to as an application processor, a central processing unit, or a main processor.

[0146] The display driver 100C can drive the display layer 100. The display driver 100C can receive image data and control signals from the main driver 1000C. The control signals can include various suitable signals. For example, the control signals can include an input vertical synchronization signal, an input horizontal synchronization signal, a main clock, and a data enable signal.

[0147] The sensor driver 200C can drive the sensor layer 200. The sensor driver 200C can receive a control signal from the main driver 1000C. The control signal may include a clock signal for the sensor driver 200C. In addition, the control signal may also include a mode determination signal for determining a driving mode of the sensor driver 200C and the sensor layer 200.

[0148] The sensor driver 200C may be implemented with an integrated circuit (IC) and may be electrically connected to the sensor layer 200. For example, the sensor driver 200C may be directly mounted on an appropriate area (e.g., a specific or predetermined area) of the display panel DP, or may be mounted on a separate printed circuit board using a chip on film (COF) method and may be electrically connected to the sensor layer 200.

[0149] The sensor driver 200C and the sensor layer 200 can selectively operate in a first mode or a second mode. For example, the first mode may be a mode for sensing touch input (e.g., such as the first input 2000). The second mode may be a mode for sensing input via a pen PN (e.g., such as the second input 3000). The first mode may be referred to as a touch sensing mode, and the second mode may be referred to as a pen sensing mode.

[0150] Switching between the first mode and the second mode can be performed in various suitable ways. For example, the sensor driver 200C and the sensor layer 200 can be driven in the first mode and the second mode in a time-division manner, and can sense the first input 2000 and the second input 3000. As another example, switching between the first mode and the second mode can be performed by a user's selection or a user's action (e.g., a specific action), or by activating or deactivating an application (e.g., a specific application). One of the first mode and the second mode can be activated or deactivated, or the driving mode can be switched from one mode to the other. As another example, when the sensor driver 200C and the sensor layer 200 operate alternately in the first mode and the second mode, when the first input 2000 is sensed, the sensor driver 200C and the sensor layer 200 can remain in the first mode, and when the second input 3000 is sensed, the sensor driver 200C and the sensor layer 200 can remain in the second mode.

[0151] The sensor driver 200C can calculate the input coordinate information based on the signal received from the sensor layer 200 and can provide a coordinate signal containing the coordinate information to the main driver 1000C. The main driver 1000C performs an operation corresponding to the user input based on the coordinate signal. For example, the main driver 1000C can operate the display driver 100C so that a new application image is displayed on the display layer 100.

[0152] The power circuit 1000P may include a power management integrated circuit (PMIC). The power circuit 1000P may generate a plurality of driving voltages for driving the display layer 100, the sensor layer 200, the display driver 100C, and the sensor driver 200C. For example, the plurality of driving voltages may include a gate high voltage, a gate low voltage, a first driving voltage (e.g., an ELVSS voltage), a second driving voltage (e.g., an ELVDD voltage), an initialization voltage, etc., but the present disclosure is not particularly limited thereto.

[0154] refer to Figure 8 At least one buffer layer (BFL) may be formed on the upper surface of the base layer 110. The buffer layer (BFL) may improve the coupling force between the base layer 110 and the semiconductor patterns SC, AL, DR, and SCL. The buffer layer (BFL) may be formed of multiple layers. As another example, the display layer 100 may further include a barrier layer. The buffer layer (BFL) may include at least one of silicon oxide, silicon nitride, and silicon oxynitride. For example, the buffer layer (BFL) may include a structure in which silicon oxide layers and silicon nitride layers are alternately stacked.

[0155] The semiconductor patterns SC, AL, DR, and SCL may be disposed on the buffer layer BFL. The semiconductor patterns SC, AL, DR, and SCL may include polysilicon.

The semiconductor patterns SC, AL, DR, and SCL may be arranged throughout the pixel according to appropriate rules (e.g., specific or predetermined rules). Depending on whether doping is performed, the semiconductor patterns SC, AL, DR, and SCL may have different electrical properties. The semiconductor patterns SC, AL, DR, and SCL may include first regions SC, DR, and SCL having higher conductivity and second regions AL having lower conductivity. The first regions SC, DR, and SCL may be doped with either N-type or P-type dopants. A P-type transistor may include a doped region doped with a P-type dopant, and an N-type transistor may include a doped region doped with an N-type dopant. The second region AL may be an undoped region or a region more lightly doped than the first regions SC, DR, and SCL.

[0157] The first regions SC, DR, and SCL may have a higher conductivity than the second region AL and may function as or substantially function as electrodes or signal lines. The second region AL may correspond to or substantially correspond to the active region AL (e.g., the channel region) of the transistor 100PC. In other words, one portion AL of the semiconductor patterns SC, AL, DR, and SCL may be the active region AL of the transistor 100PC, another portion SC or DR of the semiconductor patterns SC, AL, DR, and SCL may be the source region SC or drain region DR of the transistor 100PC, and another portion SCL of the semiconductor patterns SC, AL, DR, and SCL may be a connection electrode or a connection signal line SCL.

[0158] Each of the pixels may have an equivalent circuit including seven transistors, one capacitor, and a light emitting element, but the present disclosure is not limited thereto, and as will be understood by those of ordinary skill in the art, the equivalent circuit of the pixel may be variously modified as needed or desired.

[0170] The first electrode AE may be disposed on the sixth insulating layer 60. The first electrode AE may be connected to the second connection electrode CNE2 through a contact hole CNT-3 passing through the sixth insulating layer 60.

[0171] The pixel defining layer 70 may be disposed on the sixth insulating layer 60 and may cover a portion of the first electrode AE. The pixel defining layer 70 may have an opening 70-OP defined therein. The opening 70-OP of the pixel defining layer 70 exposes at least a portion of the first electrode AE.

[0173] The emission layer EL may be provided on the first electrode AE. The emission layer EL may be provided in a region corresponding to the opening 70-OP. In other words, an emission layer EL may be formed separately for each pixel. When an emission layer EL is formed separately for each pixel, the emission layer EL may each emit at least one of blue light, red light, and green light.

In this case, the emission layer EL may provide blue light or white light.

[0174] The second electrode CE may be disposed on the emission layer EL. The second electrode CE may have an integral shape and may be commonly included in a plurality of pixels.

[0175] In an embodiment of the present disclosure, a hole control layer may be provided between the first electrode AE and the emission layer EL.

[0178] The sensor base layer 201 may be an inorganic layer including at least one of silicon nitride, silicon oxynitride, and silicon oxide. As another example, the sensor base layer 201 may be an organic layer including epoxy resin, acrylic resin, or imide resin. The sensor base layer 201 may have a single-layer structure or a multi-layer structure stacked in the third direction DR3.

[0179] Each of the first conductive layer 202 and the second conductive layer 204 may have a single-layer structure, or may have a multi-layer structure stacked in the third direction DR3 .

[0180] Each of the first conductive layer 202 and the second conductive layer 204 having a single-layer structure may include a metal layer or a transparent conductive layer. The metal layer may include molybdenum, silver, titanium, copper, aluminum, or a suitable alloy thereof. The transparent conductive layer may include a transparent conductive oxide such as indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), indium zinc tin oxide (IZTO), etc. Furthermore, the transparent conductive layer may include a conductive polymer (such as poly(3,4-ethylenedioxythiophene) (PEDOT)), metal nanowires, or graphene.

The metal layer may have a three-layer structure of, for example, titanium / aluminum / titanium. The multi-layer conductive layer may include at least one metal layer and at least one transparent conductive layer.

[0182] In an embodiment of the present disclosure, the thickness of the first conductive layer 202 may be greater than or equal to the thickness of the second conductive layer 204. When the thickness of the first conductive layer 202 is greater than the thickness of the second conductive layer 204, the resistance of the components included in the first conductive layer 202 may be reduced. In addition, since the first conductive layer 202 may be disposed below the second conductive layer 204, even if the thickness of the first conductive layer 202 increases, the probability of visually recognizing a pattern by reflection of external light may be lower than that of the second conductive layer 204.

[0183] In an embodiment of the present disclosure, the width of the first grid lines included in the first conductive layer 202 may be less than or equal to the width of the second grid lines included in the second conductive layer 204. Because the first grid lines may have a smaller width than the second grid lines, the visual experience when viewing or observing the electronic device 1000 (e.g., referring to FIG. 1 ) may be reduced. Figure 1A ) is the probability that the user will visually identify the first grid line.

[0184] At least one of the intermediate insulating layer 203 and the capping insulating layer 205 may include an inorganic film. The inorganic film may include at least one of aluminum oxide, titanium oxide, silicon oxide, silicon nitride, silicon oxynitride, zirconium oxide, and hafnium oxide.

[0186] Although the sensor layer 200 is shown as including the first conductive layer 202 and the second conductive layer 204, or in other words, the sensor layer 200 is shown as including a total of two conductive layers, the present disclosure is not particularly limited thereto. For example, the sensor layer 200 may include three or more conductive layers.

[0187] Figure 9 is a plan view of a sensor layer 200 according to an embodiment of the present disclosure. Figure 10 is an enlarged plan view illustrating one sensing unit SU according to an embodiment of the present disclosure. Figure 11A is a plan view illustrating a first conductive layer 202SU of a sensing unit SU according to an embodiment of the present disclosure. Figure 11B is a plan view illustrating the second conductive layer 204SU of the sensing unit SU according to an embodiment of the present disclosure. Figure 12 According to the embodiment of the present disclosure Figure 11A and Figure 11B FIG. 2 is a cross-sectional view of the sensor layer 200 taken along line II′ shown in FIG.

[0188] refer to Figure 9 , a sensing region 200A and a peripheral region 200NA adjacent to the sensing region 200A may be defined in the sensor layer 200 .

[0189] The sensor layer 200 may include a plurality of first electrodes 210 , a plurality of second electrodes 220 , a plurality of third electrodes 230 , and a plurality of fourth electrodes 240 disposed in the sensing region 200A.

[0190] Each of the first electrodes 210 may intersect with the second electrode 220. Each of the first electrodes 210 may extend in the second direction DR2. The first electrodes 210 may be arranged spaced apart from each other along the first direction DR1. Each of the second electrodes 220 may extend in the first direction DR1. The second electrodes 220 may be arranged spaced apart from each other along the second direction DR2. The sensing unit SU of the sensor layer 200 may be a region (e.g., a sensing region) where one first electrode 210 and one second electrode 220 intersect with each other.

[0191] exist Figure 9 , six first electrodes 210 and ten second electrodes 220 are shown as an example, and sixty sensing units SU are shown as an example. However, the number of the first electrodes 210 and the number of the second electrodes 220 are not limited thereto.

[0192] refer to Figure 9 and Figure 10Each of the first electrodes 210 may include first dividing electrodes 210dv1 and 210dv2. The first dividing electrodes 210dv1 and 210dv2 may extend in the second direction DR2 and may be spaced apart from each other in the first direction DR1. The first dividing electrodes 210dv1 and 210dv2 may have a shape having lines symmetrical to each other with respect to a line extending in the second direction DR2.

[0193] Each of the second electrodes 220 may include second dividing electrodes 220dv1 and 220dv2. The second dividing electrodes 220dv1 and 220dv2 may extend in the first direction DR1 and may be spaced apart from each other in the second direction DR2. The second dividing electrodes 220dv1 and 220dv2 may have a shape having lines symmetrical to each other with respect to a line extending in the first direction DR1.

[0194] refer to Figure 10 、 Figure 11A 、 Figure 11B and Figure 12 Each of the second dividing electrodes 220dv1 and 220dv2 may include a sensing pattern 221 and a bridge pattern 222. The sensing pattern 221 and the bridge pattern 222 may be provided at different layers from each other (e.g., in or on a layer). The sensing pattern 221 and the bridge pattern 222 may be electrically connected to each other through the first contact hole CNa. For example, the bridge pattern 222 may be included in the first conductive layer 202SU, and the sensing pattern 221 and the first dividing electrodes 210dv1 and 210dv2 may be included in the second conductive layer 204SU. The first conductive layer 202SU may be included in the above reference Figure 8 The first conductive layer 202 described above and the second conductive layer 204SU may include Figure 8 The second conductive layer 204 is described.

[0195] Each of the third electrodes 230 may extend in the second direction DR2. The third electrodes 230 may be arranged to be spaced apart from each other along the first direction DR1. In an embodiment of the present disclosure, each of the third electrodes 230 may include a plurality of first auxiliary electrodes 230s connected in parallel to each other. Figure 9An example in which one of the third electrodes 230 includes two first auxiliary electrodes 230s is shown, but the present disclosure is not particularly limited to this. The number of the first auxiliary electrodes 230s included in each of the third electrodes 230 can be modified in various ways as needed or desired. For example, as the number of the first auxiliary electrodes 230s included in each of the third electrodes 230 increases, the resistance of each of the third electrodes 230 can be reduced, and thus power efficiency and sensing sensitivity can be improved. On the other hand, as the number of the first auxiliary electrodes 230s included in each of the third electrodes 230 decreases, the loop coil pattern formed using the third electrode 230 can be implemented in more various desired forms.

[0196] The first auxiliary electrode 230s can be arranged to correspond to the first electrode 210 in a one-to-one manner. Therefore, one sensing unit SU can include a portion of one first auxiliary electrode 230s. A coupling capacitor can be defined between one first electrode 210 and one first auxiliary electrode 230s. In this case, the induced current generated when the pen is sensed can be transmitted from the first auxiliary electrode 230s to the first electrode 210 through the coupling capacitor. In other words, the first auxiliary electrode 230s can be used to supplement the signal transmitted from the first electrode 210 to the sensor driver 200C. Therefore, when the phase of the signal induced in the first auxiliary electrode 230s is consistent with the phase of the signal induced in the first electrode 210, the maximum effect can be obtained.

[0197] The center of the first electrode 210 in the second direction DR2 may overlap with the center of the first auxiliary electrode 230s in the second direction DR2. In addition, the center of the first electrode 210 in the first direction DR1 may overlap with the center of the first auxiliary electrode 230s in the first direction DR1.

[0198] In the embodiment of the present disclosure, since one third electrode 230 includes two first auxiliary electrodes 230s, one third electrode 230 may correspond to two first electrodes 210 (for example, may overlap with two first electrodes 210). Therefore, the number of first electrodes 210 included in the sensor layer 200 may be greater than the number of third electrodes 230. For example, the number of first electrodes 210 may be equal to the product of the number of third electrodes 230 included in the sensor layer 200 and the number of first auxiliary electrodes 230s included in each of the third electrodes 230. Figure 9 , the number of the first electrodes 210 may be 6, the number of the third electrodes 230 may be 3, and the number of the first auxiliary electrodes 230s included in each of the third electrodes 230 may be 2. However, the present disclosure is not limited thereto.

[0199] The fourth electrode 240 may be arranged along the second direction DR2. The fourth electrode 240 may extend in the first direction DR1. In an embodiment of the present disclosure, each of the fourth electrodes 240 may include a second auxiliary electrode 240s1 or 240s2 connected in parallel to each other. The second auxiliary electrode 240s1 or 240s2 may include a second-first auxiliary electrode 240s1 and a second-second auxiliary electrode 240s2. Figure 9 , two fourth electrodes 240 are shown as an example. One of the two fourth electrodes 240 includes five second-first auxiliary electrodes 240s1 connected in parallel to each other, and the other of the two fourth electrodes 240 includes five second-second auxiliary electrodes 240s2 connected in parallel to each other. However, the present disclosure is not limited thereto.

[0200] In an embodiment of the present disclosure, the sensor layer 200 may include one fourth electrode. In this case, the fourth electrode 240 may include ten second auxiliary electrodes connected in parallel to each other. However, the present disclosure is not limited thereto, and the number of second auxiliary electrodes included in the fourth electrode may be modified as needed or desired.

[0201] Figure 9 An example is shown in which five second-first auxiliary electrodes 240s1 are electrically connected together, and five second-second auxiliary electrodes 240s2 are electrically connected together. In other words, the ratio between the areas of the two fourth electrodes 240, or the ratio between the number of second-first auxiliary electrodes 240s1 included in each of the two fourth electrodes 240 and the number of second-second auxiliary electrodes 240s2 included in each of the two fourth electrodes 240, may be 1:1. However, the present disclosure is not particularly limited thereto. For example, the number of second-first auxiliary electrodes 240s1 and the number of second-second auxiliary electrodes 240s2 may be different from each other.

[0202] In an embodiment of the present disclosure, when each of the fourth electrodes 240 includes the second auxiliary electrodes 240s1 or 240s2 connected in parallel to each other, an effect of increasing the area of one fourth electrode 240 can be obtained. In addition, the resistance of each of the fourth electrodes 240 can be reduced, and therefore, the second input 3000 (for example, referring to Figure 7 )’s sensing sensitivity can be improved.

[0203] A coupling capacitor may be defined between one second electrode 220 and one second auxiliary electrode 240s1 or 240s2. In this case, the induced current generated when a pen is sensed can be transmitted from the second auxiliary electrode 240s1 or 240s2 to the second electrode 220 via the coupling capacitor. In other words, the second auxiliary electrode 240s1 or 240s2 can be used to supplement the signal transmitted from the second electrode 220 to the sensor driver 200C. Therefore, the maximum effect is achieved when the phase of the signal induced in the second auxiliary electrode 240s1 or 240s2 is consistent with the phase of the signal induced in the second electrode 220. Therefore, the center of each second electrode 220 in the first direction DR1 can overlap with the center of the corresponding second auxiliary electrode 240s1 or 240s2 in the first direction DR1. Furthermore, the center of each second electrode 220 in the second direction DR2 can overlap with the center of the corresponding second auxiliary electrode 240s1 or 240s2 in the second direction DR2.

[0204] refer to Figure 9 、 Figure 11A and Figure 11B Each of the first auxiliary electrodes 230s included in the third electrode 230 may include a third-first pattern 231 and a third-second pattern 232. The third-first pattern 231 and the third-second pattern 232 may be disposed at different layers (e.g., in or on a layer). The third-first pattern 231 and the third-second pattern 232 may be electrically connected to each other via a second contact hole CNb. The third-first pattern 231 may be included in the first conductive layer 202SU, and the third-second pattern 232 may be included in the second conductive layer 204SU.

[0205] In an embodiment of the present disclosure, a portion of the third-first pattern 231 may overlap a portion of each of the first dividing electrodes 210dv1 and 210dv2. Thus, a coupling capacitor may be provided between the first electrode 210 and the third electrode 230 (e.g., may be formed between the first electrode 210 and the third electrode 230).

[0206] refer to Figure 9 、 Figure 11A and Figure 11B Each of the second auxiliary electrodes 240s1 or 240s2 included in the fourth electrode 240 includes a plurality of auxiliary patterns and an auxiliary bridge pattern 243 (e.g., a fourth-third pattern) electrically connecting the plurality of auxiliary patterns to each other. Each of the plurality of auxiliary patterns may include a first auxiliary pattern 241 (e.g., a fourth-first pattern) and a second auxiliary pattern 242 (e.g., a fourth-second pattern).

[0207] The first auxiliary pattern 241 and the auxiliary bridge pattern 243 may be disposed on the same layer (e.g., in or on the same layer). The second auxiliary pattern 242 may be disposed on a layer different from the layer on which the first auxiliary pattern 241 and the auxiliary bridge pattern 243 are disposed. The first auxiliary pattern 241 and the second auxiliary pattern 242 may be electrically connected to each other through a third contact hole CNc. The second auxiliary pattern 242 and the auxiliary bridge pattern 243 may be electrically connected to each other through a fourth contact hole CNd. The first auxiliary pattern 241 and the auxiliary bridge pattern 243 may be included in the first conductive layer 202SU, and the second auxiliary pattern 242 may be included in the second conductive layer 204SU.

[0208] In an embodiment of the present disclosure, a portion of the first auxiliary pattern 241 may overlap the sensing pattern 221 of each of the second dividing electrodes 220dv1 and 220dv2 . Therefore, a coupling capacitor may be defined (eg, provided or formed) between the second electrode 220 and the fourth electrode 240 .

[0209] In an embodiment of the present disclosure, the first conductive layer 202SU may further include dummy patterns DMP. Each of the dummy patterns DMP may be electrically floating or electrically grounded. In an embodiment of the present disclosure, the dummy patterns DMP may be omitted as needed or desired. Because the dummy patterns DMP may be provided in an empty space, the probability that a specific pattern will be visually recognized due to reflection of external light may be reduced. In other words, an electronic device 1000 (e.g., referring to FIG. 1 ) may be provided in which visibility due to reflection of external light is improved. Figure 1A ).

[0210] The sensor layer 200 may further include a plurality of first traces 210t disposed in the peripheral area 200NA, a plurality of first pads PD1 connected one-to-one to the first traces 210t, a plurality of second traces 220t, and a plurality of second pads PD2 connected one-to-one to the second traces 220t.

[0211] The first traces 210t can be electrically connected to the first electrodes 210 in a one-to-one correspondence. The two first dividing electrodes 210dv1 and 210dv2 included in one first electrode 210 can be connected to one of the first traces 210t. Each of the first traces 210t may include two first branching portions for connecting to the corresponding two first dividing electrodes 210dv1 and 210dv2. In an embodiment of the present disclosure, the two first dividing electrodes 210dv1 and 210dv2 can be connected to each other in the sensing area 200A.

[0212] The second traces 220t can be electrically connected to the second electrodes 220 in a one-to-one correspondence. The two second dividing electrodes 220dv1 and 220dv2 included in one second electrode 220 can be connected to one second trace in the second traces 220t. Each of the second traces 220t may include two second branching portions for connecting to the corresponding two second dividing electrodes 220dv1 and 220dv2. In an embodiment of the present disclosure, the two second dividing electrodes 220dv1 and 220dv2 can be connected to each other in the sensing area 200A.

[0213] The second trace 220t may include a second-first trace 220t1 and a second-second trace 220t2. The second-first trace 220t1 is connected to the second-first electrode 220s1 of the second electrode 220, and the second-second trace 220t2 is connected to the second-second electrode 220s2 of the second electrode 220. The wiring direction of the second-first electrode 220s1 may be different from the wiring direction of the second-second electrode 220s2.

[0214] As used herein, when the routing directions differ, the locations of the connection portions connecting electrodes and traces differ. For example, the location of the first connection portion connecting the second-first electrode 220s1 and the second-first trace 220t1 may differ from the location of the second connection portion connecting the second-second electrode 220s2 and the second-second trace 220t2. The first connection portion may be located at a first end of the second-first electrode 220s1 on a first side (e.g., the right side) of the sensing region 200A, and the second connection portion may be located at a second end of the second-second electrode 220s2 on a second side (e.g., the left side) of the sensing region 200A that is opposite (e.g., facing away from) the first side.

[0215] The sensor layer 200 may further include a third trace 230rt1 disposed in the peripheral area 200NA, a plurality of third pads PD3 connected to one end and opposite ends of the third trace 230rt1, a fourth trace 240t, and fourth pads PD4 connected to the fourth trace 240t in a one-to-one correspondence.

[0216] The third trace 230rt1 may be electrically connected to at least one of the first auxiliary electrodes 230s. In an embodiment of the present disclosure, the third trace 230rt1 may be electrically connected to all of the first auxiliary electrodes 230s. In other words, the third trace 230rt1 may be electrically connected to all of the third electrodes 230. The third trace 230rt1 may include a first line portion 231t extending in the first direction DR1 and electrically connected to the third electrode 230, a second line portion 232t extending from a first end of the first line portion 231t in the second direction DR2, and a third line portion 233t extending from a second end of the first line portion 231t in the second direction DR2.

[0217] In an embodiment of the present disclosure, each of the resistance of the second line portion 232t and the resistance of the third line portion 233t can be the same as or substantially the same as the resistance of one of the third electrodes 230. Therefore, the second line portion 232t and the third line portion 233t can function as the other of the third electrodes 230, and can achieve the same or substantially the same effect as that of providing the third electrode 230 in the peripheral area 200NA. For example, one of the second line portion 232t and the third line portion 233t and one of the third electrodes 230 can form a coil. Therefore, a pen located in an area adjacent to the peripheral area 200NA can also be fully charged through a loop including the second line portion 232t or the third line portion 233t.

[0218] In an embodiment of the present disclosure, in order to adjust the resistance of the second line portion 232t and the resistance of the third line portion 233t, the widths of the second line portion 232t and the third line portion 233t in the first direction DR1 may be adjusted differently. However, the present disclosure is not limited thereto, and in some embodiments, the first line portion 231t, the second line portion 232t, and the third line portion 233t may have the same or substantially the same width as each other.

[0219] The fourth trace 240t includes a fourth-first trace 240t1 and a fourth-second trace 240t2. The fourth-first trace 240t1 is connected to the second-first auxiliary electrode 240s1 in the fourth electrode 240, and the fourth-second trace 240t2 is connected to the second-second auxiliary electrode 240s2 in the fourth electrode 240. The wiring direction of the second-first auxiliary electrode 240s1 may be different from the wiring direction of the second-second auxiliary electrode 240s2.

[0220] The position of the third connection portion at which the second-first auxiliary electrode 240s1 and the fourth-first trace 240t1 are connected to each other may be different from the position of the fourth connection portion at which the second-second auxiliary electrode 240s2 and the fourth-second trace 240t2 are connected to each other. The third connection portion may be located at the second end of the second-first auxiliary electrode 240s1 located on the second side (e.g., the left side) of the sensing region 200A, and the fourth connection portion may be located at the first end of the second-second auxiliary electrode 240s2 located on the first side (e.g., the right side) of the sensing region 200A.

[0221] The sensor layer 200 may further include fifth traces 230rt2 disposed in the peripheral area 200NA and fifth pads PD5 connected to the fifth traces 230rt2 in a one-to-one correspondence. The fifth traces 230rt2 may be connected to the third electrodes 230 in a one-to-one correspondence. In other words, the number of the fifth traces 230rt2 may correspond to the number of the third electrodes 230. Figure 9 , three fifth traces 230rt2 are shown as an example.

[0222] In an embodiment of the present disclosure, the fifth trace 230rt2 and the fifth pad PD5 may be omitted as needed or desired, and the charging driving mode for charging the pen may be omitted. In this case, even if no magnetic field is provided from the sensor layer 200, the sensor layer 200 can sense input by an active pen capable of emitting a magnetic field.

[0223] refer to Figure 11A and Figure 11B , in the second conductive layer 204SU in one sensing unit SU, the area occupied by the components included in the first electrode 210 and the second electrode 220 may be larger than the area occupied by the components included in the third electrode 230 and the fourth electrode 240. Figure 4 ) can increase as the distance decreases. Therefore, for sensing the first input 2000 (eg, reference Figure 4 ) components may be provided with the electronic device 1000 (eg, reference Figure 1A ). Therefore, the touch performance can be improved.

[0224] although Figures 6 to 9 The structure in which the first electrode 210, the second electrode 220, the third electrode 230, and the fourth electrode 240 are distributed and arranged in two conductive layers 202SU and 204SU is shown, but the present disclosure is not particularly limited thereto. For example, the first electrode 210, the second electrode 220, the third electrode 230, and the fourth electrode 240 may be distributed and arranged in three conductive layers or four conductive layers.

[0225] In an embodiment of the present disclosure, the third electrode 230 to which a signal is applied in the charge driving mode may be included in a third conductive layer disposed below the first conductive layer 202SU and the second conductive layer 204SU. For example, the third conductive layer may be disposed below the sensor base layer 201. The third conductive layer may be disposed between the sensor base layer 201 and the display layer 100, may be disposed below the display layer 100, or may be included in the display layer 100.

[0226] The first electrode 210, the second electrode 220, and the fourth electrode 240 may be included in the first conductive layer 202SU and the second conductive layer 204SU. For example, when the third electrode 230 is implemented as a separate conductive layer (such as the third conductive layer), the shape of the third electrode 230 can be designed more freely. For example, the third electrode 230 can be arranged in a suitable form including multiple coils. Furthermore, by using the third conductive layer, the third electrodes 230 can be arranged more densely. In this case, pen sensing sensitivity can be improved. In embodiments of the present disclosure, the fourth electrode 240 can be included in the third conductive layer instead of the third electrode 230.

The grid structure may include a plurality of grid lines. The plurality of grid lines may have a straight line shape extending in an appropriate direction (e.g., a specific or predetermined direction) and may be connected to each other. An opening not provided with the grid structure may be defined (e.g., may be provided or formed) in each of the first electrode 210, the second electrode 220, the third electrode 230, the fourth electrode 240, and the dummy pattern DMP.

[0229] Figure 13A and Figure 13B An example is shown in which the grid structure includes grid lines extending in a first crossing direction CDR1 crossing the first direction DR1 and the second direction DR2 and grid lines extending in a second crossing direction CDR2 crossing the first crossing direction CDR1. However, the extending directions of the grid lines constituting the grid structure are not particularly limited to Figure 13A and Figure 13B. For example, the grid structure may include grid lines extending in the first direction DR1 and the second direction DR2 (e.g., grid lines extending only in the first direction DR1 and the second direction DR2), or may include grid lines extending in the first direction DR1, the second direction DR2, the first cross direction CDR1, and the second cross direction CDR2. In other words, the grid structure may be modified in various suitable forms as needed or desired.

Figure 17A is a plan view showing the first conductive layer of region FF′ according to an embodiment of the present disclosure. Figure 17B is a plan view illustrating the second conductive layer of region FF′ according to an embodiment of the present disclosure.

[0231] refer to Figure 9 、 Figure 14 and Figure 16 The second-first electrode 220s1 is positioned on the upper side relative to a center line passing through the center of the sensing region 200A in the first direction DR1, and the second-second electrode 220s2 is positioned on the lower side relative to the center line. In the central portion where the center line is located, the second-first electrode 220s1 and the second-second electrode 220s2 are adjacent to each other. More specifically, a first boundary electrode 220bs1 in the second-first electrode 220s1 is adjacent to a second boundary electrode 220bs2 in the second-second electrode 220s2 in the second direction DR2.

[0232] The first boundary electrode 220bs1 is connected to the first boundary trace 220bt1 among the second-first traces 220t1, and the second boundary electrode 220bs2 is connected to the second boundary trace 220bt2 among the second-second traces 220t2. The first boundary trace 220bt1 is connected to the first end of the first boundary electrode 220bs1, and the second boundary trace 220bt2 is connected to the second end of the second boundary electrode 220bs2.

[0233] The first boundary electrode 220bs1 includes two first dividing boundary electrodes 220bv11 and 220bv12 spaced apart from each other in the second direction DR2 (eg, see Figure 15B and Figure 17B). The first dividing boundary electrodes 220bv11 and 220bv12 are commonly connected to the first boundary trace 220bt1. The second boundary electrode 220bs2 includes two second dividing boundary electrodes 220bv21 and 220bv22 spaced apart from each other in the second direction DR2. The second dividing boundary electrodes 220bv21 and 220bv22 are commonly connected to the second boundary trace 220bt2. The two first dividing boundary electrodes 220bv11 and 220bv12 may be referred to as the first-first dividing boundary electrode 220bv11 and the first-second dividing boundary electrode 220bv12, respectively. The two second dividing boundary electrodes 220bv21 and 220bv22 may be referred to as the second-first dividing boundary electrode 220bv21 and the second-second dividing boundary electrode 220bv22, respectively. The first-second dividing boundary electrode 220bv12 may be adjacent to the second-first dividing boundary electrode 220bv21.

[0234] refer to Figures 14 to 17B The dummy pattern DMP includes a first dummy boundary pattern DMP_b1 that overlaps with the first boundary electrode 220bs1 and a second dummy boundary pattern DMP_b2 that overlaps with the second boundary electrode 220bs2. The first boundary electrode 220bs1 is connected to the first dummy boundary pattern DMP_b1 via a first compensation contact hole CT1. The second boundary electrode 220bs2 is connected to the second dummy boundary pattern DMP_b2 via a second compensation contact hole CT2.

[0235] In an embodiment of the present disclosure, the first-second dividing boundary electrode 220bv12 of the first boundary electrode 220bs1 may be connected to the first boundary dummy pattern DMP_b1 via a first compensation contact hole CT1. However, the present disclosure is not limited thereto. As another example, the first-first dividing boundary electrode 220bv11 and the first-second dividing boundary electrode 220bv12 may be connected to the first boundary dummy pattern DMP_b1 via a first compensation contact hole CT1. In an embodiment of the present disclosure, the second-first dividing boundary electrode 220bv21 of the second boundary electrode 220bs2 may be connected to the second boundary dummy pattern DMP_b2 via a second compensation contact hole CT2. However, the present disclosure is not limited thereto. As another example, the second-first dividing boundary electrode 220bv21 and the second-second dividing boundary electrode 220bv22 may be connected to the second boundary dummy pattern DMP_b2 via a second compensation contact hole CT2.

[0236] The number of first compensation contact holes CT1 may increase from the center point of the first boundary electrode 220bs1 toward the second end of the first boundary electrode 220bs1. In addition, the number of first compensation contact holes CT1 may increase from the center point of the first boundary electrode 220bs1 toward the first end of the first boundary electrode 220bs1. The number of first compensation contact holes CT1 at the second end of the first boundary electrode 220bs1 may be different from the number of first compensation contact holes CT1 at the first end of the first boundary electrode 220bs1.

[0237] The number of second compensation contact holes CT2 may increase from the center point of the second boundary electrode 220bs2 toward the first end of the second boundary electrode 220bs2. In addition, the number of second compensation contact holes CT2 may increase from the center point of the second boundary electrode 220bs2 toward the second end of the second boundary electrode 220bs2. The number of second compensation contact holes CT2 at the first end of the second boundary electrode 220bs2 may be different from the number of second compensation contact holes CT2 at the second end of the second boundary electrode 220bs2.

[0238] In addition, the number of first compensation contact holes CT1 at the second end of the first boundary electrode 220bs1 may be different from the number of second compensation contact holes CT2 at the second end of the second boundary electrode 220bs2, and the number of first compensation contact holes CT1 at the first end of the first boundary electrode 220bs1 may be different from the number of second compensation contact holes CT2 at the first end of the second boundary electrode 220bs2.

[0239] Figure 18 1 shows a diagram depicting the mutual capacitance Cm of the first boundary electrode 220bs1 and the second boundary electrode 220bs2 according to an embodiment of the present disclosure. Figure 18 , the first graph G1 and the second graph G2 depict a structure in which the first compensation contact hole CT1 and the second compensation contact hole CT2 are not provided (eg, referring to FIG. 1 ). Figure 14 and Figure 16 ) in the structure of the first boundary electrode 220bs1 and the second boundary electrode 220bs2 mutual capacitance Cm. Figure 18 , the first graph G1a and the second graph G2a depict a first compensation contact hole CT1 and a second compensation contact hole CT2 (eg, referring to FIG. 1 ). Figure 14 and Figure 16 ) in the structure of the first boundary electrode 220bs1 and the second boundary electrode 220bs2.

[0240] refer to Figure 14 、 Figure 16 and Figure 18When the first boundary electrode 220bs1 and the first boundary dummy pattern DMP_b1 are not connected to each other through the first compensation contact hole CT1, the mutual capacitance Cm of the first boundary electrode 220bs1 may vary depending on the position. When the number of the first compensation contact holes CT1 is adjusted according to the position to compensate for the variation in the mutual capacitance Cm as in some embodiments of the present disclosure described above, the mutual capacitance Cm of the first boundary electrode 220bs1 may not vary depending on the position.

[0241] When the second boundary electrode 220bs2 and the second boundary dummy pattern DMP_b2 are not connected to each other through the second compensation contact hole CT2, the mutual capacitance Cm of the second boundary electrode 220bs2 may vary depending on the position. When the number of second compensation contact holes CT2 is adjusted according to the position to compensate for the variation in the mutual capacitance Cm as in some embodiments of the present disclosure, the mutual capacitance Cm of the second boundary electrode 220bs2 may not vary depending on the position.

[0242] Furthermore, when the mutual capacitance Cm of the first boundary electrode 220bs1 and the second boundary electrode 220bs2 is compensated by adjusting the number of the first compensation contact holes CT1 and the second compensation contact holes CT2, the variation in the mutual capacitance Cm between the first boundary electrode 220bs1 and the second boundary electrode 220bs2 can also be reduced. In other words, the phenomenon in which the difference in the mutual capacitance Cm between the first end of the first boundary electrode 220bs1 and the first end of the second boundary electrode 220bs2 and the difference in the mutual capacitance Cm between the second end of the first boundary electrode 220bs1 and the second end of the second boundary electrode 220bs2 are greater than the difference in the mutual capacitance Cm in the central portion can be prevented or substantially prevented.

[0243] Figure 19 It shows Figure 9 An enlarged plan view of the first conductive layer in the region EE' is shown in FIG. Figure 20 It is shown that Figure 19 A plan view of the first conductive layer in areas AA1, AA2 and AA3 shown in FIG. Figure 21 It shows Figure 9 An enlarged plan view of the first conductive layer in the region FF′ is shown in FIG. Figure 22 It is shown that Figure 21 A plan view of the first conductive layer in areas AA4, AA5 and AA6 is shown in FIG.

[0244] refer to Figures 19 to 22 , dummy pattern DMP (for example, reference Figure 10) may include a first boundary dummy pattern DMP_b1 connected to the first boundary electrode 220bs1 and a second boundary dummy pattern DMP_b2 connected to the second boundary electrode 220bs2. The first boundary electrode 220bs1 may be connected to the first boundary dummy pattern DMP_b1, and the second boundary electrode 220bs2 may be connected to the second boundary dummy pattern DMP_b2.

[0245] Each of the first and second dummy border patterns DMP_b1 and DMP_b2 may include grid lines, and the width of the grid lines may vary or differ depending on the location. The width of the grid lines of the first dummy border pattern DMP_b1 may be determined based on the distance from the first boundary trace 220bt1 connected to the first boundary electrode 220bs1 among the second-first traces 220t1. The width of the grid lines of the second dummy border pattern DMP_b2 may be determined based on the distance from the second boundary trace 220bt2 connected to the second boundary electrode 220bs2 among the second-second traces 220t2.

[0246] Figure 20 Shown Figure 19 The first area AA1 is closer to the first boundary trace 220bt1 than the second area AA2 and the third area AA3, and the second area AA2 is closer to the first boundary trace 220bt1 than the third area AA3.

[0247] The grid lines of the first border dummy pattern DMP_b1 in the first area AA1 have a first width W1, the grid lines of the first border dummy pattern DMP_b1 in the second area AA2 have a second width W2, and the grid lines of the first border dummy pattern DMP_b1 in the third area AA3 have a third width W3. In an embodiment of the present disclosure, the second width W2 may be greater than the first width W1, and the third width W3 may be greater than the second width W2.

[0248] By including the grid lines of the first boundary dummy pattern DMP_b1 having different widths depending on the distance from the first boundary trace 220bt1, the variation in the mutual capacitance Cm of the first boundary electrode 220bs1 according to the position can be compensated. Therefore, the mutual capacitance Cm of the first boundary electrode 220bs1 may not vary or substantially not vary according to the position in the first direction DR1.

[0249] Figure 22 Shown Figure 21The fourth area AA4, the fifth area AA5 and the sixth area AA6 are shown in FIG. The fourth area AA4 is closer to the second boundary trace 220bt2 than the fifth area AA5 and the sixth area AA6, and the fifth area AA5 is closer to the second boundary trace 220bt2 than the sixth area AA6.

[0250] The grid lines of the second border dummy pattern DMP_b2 in the fourth area AA4 have a fourth width W4, the grid lines of the second border dummy pattern DMP_b2 in the fifth area AA5 have a fifth width W5, and the grid lines of the second border dummy pattern DMP_b2 in the sixth area AA6 have a sixth width W6. In an embodiment of the present disclosure, the fifth width W5 may be greater than the fourth width W4, and the sixth width W6 may be greater than the fifth width W5.

[0251] By including the grid lines of the second boundary dummy pattern DMP_b2 having different widths depending on the distance from the second boundary trace 220bt2, the variation in mutual capacitance Cm of the second boundary electrode 220bs2 according to the position can be compensated. Therefore, the mutual capacitance Cm of the second boundary electrode 220bs2 may not vary or substantially not vary according to the position in the first direction DR1.

[0252] Furthermore, by adjusting the width of the grid lines of first and second boundary dummy patterns DMP_b1 and DMP_b2 to compensate for the mutual capacitance Cm of first and second boundary electrodes 220bs1 and 220bs2, variations in mutual capacitance Cm between first and second boundary electrodes 220bs1 and 220bs2 can also be reduced. In other words, the phenomenon in which the difference in mutual capacitance Cm between the first end of first boundary electrode 220bs1 and the first end of second boundary electrode 220bs2 and the difference in mutual capacitance Cm between the second end of first boundary electrode 220bs1 and the second end of second boundary electrode 220bs2 are greater than the difference in mutual capacitance Cm in the central portion can be prevented or substantially prevented.

[0253] Figure 23 200C is a diagram illustrating the operation of the sensor driver 200C according to the embodiment of the present disclosure.

[0254] refer to Figure 7 and Figure 23 , the sensor driver 200C may be selectively driven in one of the first operation mode DMD1 , the second operation mode DMD2 , and the third operation mode DMD3 .

[0255] The first operating mode DMD1 may be referred to as a touch and pen standby mode. The second operating mode DMD2 may be referred to as a touch active and pen standby mode. The third operating mode DMD3 may be referred to as a pen active mode. The first operating mode DMD1 may be a mode in which the sensor driver 200C waits for the first input 2000 and the second input 3000. The second operating mode DMD2 may be a mode in which the sensor driver 200C senses the first input 2000 and waits for the second input 3000. The third operating mode DMD3 may be a mode in which the sensor driver 200C senses the second input 3000.

[0256] In an embodiment of the present disclosure, the sensor driver 200C may be initially driven in the first operating mode DMD1. When a first input 2000 is sensed in the first operating mode DMD1, the sensor driver 200C may switch (e.g., change) to the second operating mode DMD2. As another example, when a second input 3000 is sensed in the first operating mode DMD1, the sensor driver 200C may switch (e.g., change) to the third operating mode DMD3.

[0257] In an embodiment of the present disclosure, when the second input 3000 is sensed in the second operating mode DMD2, the sensor driver 200C may switch to the third operating mode DMD3. When the first input 2000 is released (e.g., not sensed) in the second operating mode DMD2, the sensor driver 200C may switch to the first operating mode DMD1. When the second input 3000 is released (e.g., not sensed) in the third operating mode DMD3, the sensor driver 200C may switch to the first operating mode DMD1.

[0258] Figure 24 200C is a diagram illustrating the operation of the sensor driver 200C according to the embodiment of the present disclosure.

[0259] refer to Figure 7 、 Figure 23 and Figure 24 , operations in the first operation mode DMD1 , the second operation mode DMD2 , and the third operation mode DMD3 are shown in order of time (t).

[0260] In the first operation mode DMD1, the sensor driver 200C may be repeatedly driven in the second mode MD2-d and the first mode MD1-d. During the second mode MD2-d, the sensor layer 200 may be scan-driven to detect the second input 3000. During the first mode MD1-d, the sensor layer 200 may be scan-driven to detect the first input 2000. Although Figure 24An example is shown in which the sensor driver 200C operates in the first mode MD1 - d continuously after the second mode MD2 - d , but the present disclosure is not limited thereto, and the order thereof may be variously modified as needed or desired.

[0261] In the second operating mode DMD2, the sensor driver 200C may be repeatedly driven in the second mode MD2-d and the first mode MD1. During the second mode MD2-d, the sensor layer 200 may be scan-driven to detect the second input 3000. During the first mode MD1, the sensor layer 200 may be scan-driven to detect the coordinates of the first input 2000.

[0262] In the third operating mode DMD3, the sensor driver 200C may be driven in the second mode MD2. During the second mode MD2, the sensor layer 200 may be scan-driven to detect the coordinates of the second input 3000. In the third operating mode DMD3, the sensor driver 200C may not operate in the first mode MD1-D or MD1 until the second input 3000 is released (e.g., not sensed).

[0263] refer to Figure 9 and Figure 24 In the first mode MD1-d and the first mode MD1, the third electrode 230 and the fourth electrode 240 may all be grounded. Therefore, the introduction of touch noise through the third electrode 230 and the fourth electrode 240 may be prevented or substantially prevented.

[0264] In the first operating mode DMD1 or the second mode MD2-d of the second operating mode DMD2, and the second mode MD2 of the third operating mode DMD3, the first ends of the third electrode 230 and the fourth electrode 240 can all be floating. Furthermore, in the second mode MD2-d and the second mode MD2, the second ends of the third electrode 230 and the fourth electrode 240 can all be grounded or floating. Therefore, through the coupling between the first electrode 210 and the third electrode 230, and the coupling between the second electrode 220 and the fourth electrode 240, compensation of the sensing signal can be increased or maximized.

[0265] Figure 25A is a view showing a first mode of embodiment according to the present disclosure. Figure 25B is a view showing a first mode of embodiment according to the present disclosure.

[0266] Refer to Figure 17. Figure 25A and Figure 25B , the first mode MD1 - d and the first mode MD1 - d may include at least one of a self-capacitance detection mode and a mutual capacitance detection mode. Figure 25A and Figure 25Bis a diagram showing the operation of the self-capacitance detection mode.

[0267] In the self-capacitance detection mode, the sensor driver 200C can calculate the input coordinates by outputting a transmission signal TX to at least one of the first electrode 210 and the second electrode 220 and sensing a change in capacitance of at least one of the first electrode 210 and the second electrode 220. Figure 25A and Figure 25B An example is shown in which the sensor driver 200C outputs the transmission signal TX to the first trace 210t connected to the first electrode 210, but the present disclosure is not limited thereto. As another example, the sensor driver 200C may output the transmission signal TX to the second trace 220t connected to the second electrode 220. Furthermore, when the self-capacitance detection mode includes two subsections (e.g., a first subsection and a second subsection), the sensor driver 200C may output the transmission signal TX to the first trace 210t during the first subsection, and may output the transmission signal TX to the second trace 220t during the second subsection.

[0268] The third electrode 230 is electrically connected to the third trace 230rt1 and the fifth trace 230rt2, and the fourth electrode 240 is electrically connected to the fourth trace 240t. In the self-capacitance detection mode, the third electrodes 230 can be grounded. Therefore, noise can be prevented from being introduced through the third electrodes 230.

[0269] As another example, in the self-capacitance detection mode, all of the third electrodes 230 may be floating or may receive a reference voltage (e.g., a preset or predetermined reference voltage). In an embodiment of the present disclosure, a signal in phase with the transmission signal TX may be applied to the third electrodes 230. In this case, noise may not be introduced through the third electrodes 230.

[0270] In an embodiment of the present disclosure, in the self-capacitance detection mode, a first compensation voltage Vb1 may be applied to the second-first auxiliary electrode 240s1 of the fourth electrode 240, and a second compensation voltage Vb2 may be applied to the second-second auxiliary electrode 240s2. In the self-capacitance detection mode, the sensor driver 200C may output the first compensation voltage Vb1 to the fourth-first trace 240t1, and may output the second compensation voltage Vb2 to the fourth-second trace 240t2.

[0271] In an embodiment of the present disclosure, the first compensation voltage Vb1 and the second compensation voltage Vb2 may have different voltage levels. The voltage levels of the first compensation voltage Vb1 and the second compensation voltage Vb2 may be determined to appropriately compensate for the difference in mutual capacitance Cm between the first boundary electrode 220bs1 and the second boundary electrode 220bs2. Therefore, the difference in mutual capacitance Cm between the first boundary electrode 220bs1 and the second boundary electrode 220bs2 may be reduced, and thus, changes in capacitance may be accurately sensed in the self-capacitance detection mode.

[0272] refer to Figure 25B Fourth trace 240ta may include a fourth-first trace 240t1, a fourth-second trace 240t2, a first auxiliary boundary trace 240bt1, and a second auxiliary boundary trace 240bt2. First auxiliary boundary trace 240bt1 is connected to first auxiliary boundary electrode 240bs1 in fourth electrode 240a, and second auxiliary boundary trace 240bt2 is connected to second auxiliary boundary electrode 240bs2 in fourth electrode 240a. First auxiliary boundary electrode 240bs1 overlaps with first boundary electrode 220bs1 to form a coupling capacitor, and second auxiliary boundary electrode 240bs2 overlaps with second boundary electrode 220bs2 to form a coupling capacitor.

[0273] In the self-capacitance detection mode, the third electrode 230, the second-first auxiliary electrode 240s1, and the second-second auxiliary electrode 240s2 can all be grounded. Therefore, noise can be prevented from being introduced through the third electrode 230, the second-first auxiliary electrode 240s1, and the second-second auxiliary electrode 240s2. As another example, in the self-capacitance detection mode, the third electrode 230, the second-first auxiliary electrode 240s1, and the second-second auxiliary electrode 240s2 can all be floating or receive a reference voltage (e.g., a preset or predetermined reference voltage).

[0274] In an embodiment of the present disclosure, in the self-capacitance detection mode, a first compensation voltage Vb1 may be applied to the first auxiliary boundary electrode 240bs1 of the fourth electrode 240, and a second compensation voltage Vb2 may be applied to the second auxiliary boundary electrode 240bs2. In the self-capacitance detection mode, the sensor driver 200C may output the first compensation voltage Vb1 to the first auxiliary boundary trace 240bt1, and may output the second compensation voltage Vb2 to the second auxiliary boundary trace 240bt2.

[0275] In an embodiment of the present disclosure, the first compensation voltage Vb1 and the second compensation voltage Vb2 may have different voltage levels from each other. The coupling capacitance between the first auxiliary boundary electrode 240bs1 and the first boundary electrode 220bs1 may vary according to the first compensation voltage Vb1, and the coupling capacitance between the second auxiliary boundary electrode 240bs2 and the second boundary electrode 220bs2 may vary according to the second compensation voltage Vb2.

[0276] The voltage levels of first compensation voltage Vb1 and second compensation voltage Vb2 can be determined to appropriately compensate for the difference in mutual capacitance Cm between first boundary electrode 220bs1 and second boundary electrode 220bs2. By adjusting the voltage levels of first compensation voltage Vb1 and second compensation voltage Vb2, the magnitude of the coupling capacitance can be controlled, thereby reducing the difference in mutual capacitance Cm between first boundary electrode 220bs1 and second boundary electrode 220bs2. When the difference in mutual capacitance Cm between first boundary electrode 220bs1 and second boundary electrode 220bs2 is reduced, changes in capacitance can be accurately sensed in the central portion of sensing area 200A.

[0277] Figure 26 is a view showing a first mode of embodiment according to the present disclosure.

[0278] refer to Figure 7 、 Figure 24 and Figure 26 , the first mode MD1-d and the first mode MD1 may further include a mutual capacitance detection mode. Figure 26 2 is a diagram illustrating the mutual capacitance detection mode in the first mode MD1 - d and the first mode MD1 .

[0279] In the mutual capacitance detection mode, the sensor driver 200C may sequentially provide a transmission signal TX to the first electrode 210, and may detect the coordinates of the first input 2000 using a reception signal RX detected by the second electrode 220. For example, the sensor driver 200C may sense a change in mutual capacitance between the first electrode 210 and the second electrode 220, and may calculate the input coordinates.

[0280] Figure 26 2 shows an example in which a transmission signal TX is supplied to one first electrode 210 and a reception signal RX is output from the second electrode 220. Figure 26 In FIG. 2 , to clarify the representation of the signal, hatching is drawn only on one first electrode 210 to which the transmission signal TX is supplied. The sensor driver 200C can sense a change in capacitance between the first electrode 210 and the second electrode 220 and can detect the input coordinates of the first input 2000 .

[0281] In mutual capacitance detection mode, all third electrodes 230 can be grounded. Therefore, noise can be prevented from being introduced through the third electrodes 230. As another example, in mutual capacitance detection mode, all third electrodes 230 can be floating or receive a reference voltage (e.g., a preset or predetermined reference voltage). In embodiments of the present disclosure, a signal in phase with the transmission signal TX can be applied to the third electrodes 230. In this case, noise can be prevented from being introduced through the third electrodes 230.

[0282] In an embodiment of the present disclosure, in the mutual capacitance detection mode, a first compensation voltage Vb1 may be applied to the second-first auxiliary electrode 240s1 of the fourth electrode 240, and a second compensation voltage Vb2 may be applied to the second-second auxiliary electrode 240s2. In the mutual capacitance detection mode, the sensor driver 200C may output the first compensation voltage Vb1 to the fourth-first trace 240t1, and may output the second compensation voltage Vb2 to the fourth-second trace 240t2.

[0283] In an embodiment of the present disclosure, the first compensation voltage Vb1 and the second compensation voltage Vb2 may have different voltage levels. The voltage levels of the first compensation voltage Vb1 and the second compensation voltage Vb2 may be determined to appropriately compensate for the difference in mutual capacitance Cm between the first boundary electrode 220bs1 and the second boundary electrode 220bs2. Therefore, the difference in mutual capacitance Cm between the first boundary electrode 220bs1 and the second boundary electrode 220bs2 may be reduced, and thus, changes in capacitance may be accurately sensed in the mutual capacitance detection mode.

[0284] In the first mode MD1-d of the first operating mode DMD1 and the first mode MD1 of the second operating mode DMD2, the sensor layer 200 may alternately repeat the self-capacitance detection operation and the mutual capacitance detection operation. However, the present disclosure is not limited thereto. For example, in each of the first mode MD1-d and the first mode MD1, the sensor layer 200 may only repeat the mutual capacitance detection operation. As another example, in the first mode MD1-d, the sensor layer 200 may only repeat the self-capacitance detection operation or the mutual capacitance detection operation, and in the first mode MD1, the sensor layer 200 may alternately repeat the self-capacitance detection operation and the mutual capacitance detection operation.

[0285] Figure 27 is a view showing a second mode according to an embodiment of the present disclosure. Figure 28A Graphs depicting waveforms of a first signal and a second signal are shown according to an embodiment of the present disclosure. Figure 28B Graphs depicting waveforms of a first signal and a second signal are shown according to an embodiment of the present disclosure. Figure 28CGraphs depicting waveforms of a first signal and a second signal are shown according to an embodiment of the present disclosure.

[0286] refer to Figure 24 and Figure 27 The second mode MD2 may include a charging driving mode and a pen sensing driving mode. In addition, the charging driving mode may include a search charging driving mode and a tracking charging driving mode. Figure 27 is a view showing a search charging driving mode.

[0287] refer to Figure 24 、 Figure 27 and Figure 28A In the charging driving mode, the sensor driver 200C may apply a first signal SG1 to at least one of the third pad PD3 and the fifth pad PD5, and may apply a second signal SG2 to at least one other pad. The second signal SG2 may be an inverse signal of the first signal SG1. For example, the first signal SG1 may be a sinusoidal signal.

[0288] although Figure 27 An example is shown in which the first signal SG1 is applied to one pad and the second signal SG2 is applied to another pad, but the present disclosure is not limited thereto. For example, the first signal SG1 may be applied to two or more pads, and the second signal SG2 may be applied to two or more other pads.

[0289] Because the first signal SG1 and the second signal SG2 are applied to at least two pads, the current can have a current path flowing through at least one pad to at least one other pad. In addition, because the first signal SG1 and the second signal SG2 can be sinusoidal signals with opposite phases, the direction of the current can change periodically.

[0290] refer to Figure 27 and Figure 28B , first signal SG1a and second signal SG2a can be square wave signals. Second signal SG2a can be an inverted signal of first signal SG1a. Because first signal SG1a and second signal SG2a are applied to at least two pads, current can have a current path that flows through at least one pad to at least one other pad. Furthermore, because first signal SG1a and second signal SG2a can be square wave signals with opposite phases, the direction of the current can change periodically.

[0291] Figure 28A and Figure 28B The first signal SG1 or SG1a shown in FIG. 4 may have an inverse relationship with the second signal SG2 or SG2a. Therefore, the first signal SG1 or SG1a may be used to generate an inverse relationship between the first signal SG1 and the second signal SG2a. Figure 7) can be offset by the noise caused by the second signal SG2 or SG2a. Therefore, a flicker phenomenon may not occur in the display layer 100, and the display quality of the display layer 100 may be improved.

[0292] refer to Figure 27 and Figure 28C , first signal SG1 may be a sinusoidal signal. However, this is not limiting and first signal SG1 may be a square wave signal. Second signal SG2b may have a constant voltage (e.g., a specific or predetermined constant voltage). For example, second signal SG2b may be a ground voltage. In other words, the pad to which second signal SG2b is applied may be considered to be grounded. Even in this case, current may flow from at least one pad to at least one other pad. Furthermore, even if at least one other pad is grounded, the direction of the current may change periodically because first signal SG1 may be a sinusoidal or square wave signal.

[0293] refer to Figure 27 , the second signal SG2 is provided to a third pad PD3a connected to a third trace 230rt1, and the first signal SG1 is provided to a fifth pad PD5a connected to the third electrode 230. Current can flow along a current path defined by the fifth pad PD5a, the fifth trace 230rt2 connected to the fifth pad PD5a, the third electrode 230, a portion of the third trace 230rt1 connected to the third pad PD3a, and the third pad PD3a. The current path can have a coil shape. Therefore, in the charging drive mode of the second mode MD2, the resonant circuit of the pen PN can be charged through the current path.

[0294] According to some embodiments of the present disclosure, a current path having a loop coil pattern may be implemented by components included in the sensor layer 200. Therefore, the electronic device 1000 (eg, referring to Figure 1A ) The pen PN can be charged using the sensor layer 200. Therefore, a component having a coil for charging the pen PN may not be separately added, so that an increase in thickness and weight of the electronic device 1000 and a decrease in flexibility of the electronic device 1000 may not occur.

[0295] In the charging drive mode, the first electrode 210, the second electrode 220, and the fourth electrode 240 may be grounded or electrically floating, or may receive a constant voltage. More specifically, the first electrode 210, the second electrode 220, and the fourth electrode 240 may be floating. In this case, current may not flow to the first electrode 210, the second electrode 220, and the fourth electrode 240.
