[0075] Aspects of some embodiments of the present disclosure and methods for implementing them can be more easily understood by reference to the detailed description of the embodiments and the accompanying drawings. The described embodiments are provided as examples so that the present disclosure will be thorough and complete, and will fully convey aspects of the present disclosure to those skilled in the art. Therefore, redundant, irrelevant or unrelated to the description of the embodiments or unnecessary processes, elements and techniques for a complete understanding of aspects of the present disclosure by those of ordinary skill in the art can be omitted. Unless otherwise stated, in all drawings and written descriptions, the same reference numerals, characters or combinations thereof represent the same elements, and therefore, their repeated descriptions can be omitted.

[0076] The described embodiments may have various modifications and may be implemented in different forms, and should not be construed as being limited to the embodiments shown herein. The "may", "can" or "may not" used in describing the embodiments corresponds to one or more embodiments of the present disclosure. The present disclosure encompasses all modifications, equivalents and substitutions within the conceptual and technical scope of the present disclosure. In addition, each of the features of the various embodiments of the present disclosure may be partially combined with each other or combined with each other as a whole, and various interlocks and drives are technically possible. Each embodiment may be implemented independently of one another, or may be implemented together in association.

[0077] In the drawings, the relative sizes of elements, layers, and regions may be exaggerated for clarity and / or descriptive purposes. In addition, cross-hatching and / or shading are generally used in the drawings to make the boundaries between adjacent elements clear. Therefore, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for specific materials, material properties, dimensions, proportions, commonalities between the elements shown, and / or any other characteristics, attributes, properties, etc. of the elements.

[0078] Various embodiments are described herein with reference to cross-sectional views as schematic diagrams of embodiments and / or intermediate structures. In this way, deviations from the illustrated shapes caused by, for example, manufacturing techniques and / or tolerances are expected. In addition, the specific structural or functional descriptions disclosed herein are merely illustrative for the purpose of describing embodiments according to the concepts of the present disclosure. Therefore, the embodiments disclosed herein should not be interpreted as being limited to the illustrated shapes of elements, layers, or regions, but will include deviations from shapes caused by, for example, manufacturing.

[0079] For example, an implanted region illustrated as a rectangle will, typically, have rounded or curved features and / or a gradient of implant concentration at its edges rather than a binary change from implanted to non-implanted region. Likewise, a buried region formed by implantation may result in some implantation in the region between the buried region and the surface through which the implantation takes place.

[0080] For ease of explanation, spatially relative terms such as "below", "below", "lower", "lower side", "below", "above", "upper", "upper side" and the like may be used herein to describe the relationship between an element or feature and another (some) element or feature as shown in the figure. It will be understood that, in addition to the orientation depicted in the accompanying drawings, spatially relative terms are intended to include different orientations of the device in use or operation. For example, if the device in the accompanying drawings is turned over, the elements described as being "below", "below" or "below" other elements or features will then be oriented "above" other elements or features. Therefore, the exemplary terms "below" and "below" can cover both upper and lower orientations. The device can 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. Similarly, when a first portion is described as being arranged "on" a second portion, this indicates that the first portion is arranged at the upper or lower side of the second portion, without being limited to its upper side based on the direction of gravity.

[0081] In addition, the phrase "in a plan view" means when the object portion is observed from above, and the phrase "in a schematic cross-sectional view" means when the schematic cross-section obtained by vertically cutting the object portion is observed from the side. The term "overlap" or "overlapping" means that the first object can be above or below the second object or on one side of the second object, and conversely, the second object can be above or below the first object or on one side of the first object. In addition, the term "overlap" can include stacking, facing or facing, extending throughout..., covering or partially covering, or any other suitable term as will be understood and appreciated by a person of ordinary skill in the art. The expression "non-overlapping" can include meanings such as "separated from..." or "set beside..." or "deviation from..." and any other suitable equivalents as will be understood and appreciated by a person of ordinary skill in the art. The terms "facing" and "facing" can mean that the first object can be directly opposite to the second object or indirectly opposite to the second object. In the case where a third object is inserted between the first object and the second object, the first object and the second object can be understood to be indirectly opposite to each other, but still facing each other.

[0082] It will be understood that when an element, layer, region, or component is referred to as being "formed on," "on," "connected to," or "(operably or communicatively) coupled to" another element, layer, region, or component, it may be formed directly on, or directly on, or directly connected to, or directly coupled to, another element, layer, region, or component, or indirectly formed on, or indirectly on, or indirectly connected to, or indirectly coupled to, another element, layer, region, or component such that one or more intervening elements, layers, regions, or components may be present. Additionally, this may generally mean direct or indirect coupling or connection, and integral or non-integral coupling or connection. For example, when an element, layer, region, or component is referred to as being "electrically connected" or "electrically coupled" to another element, layer, region, or component, it may be directly electrically connected to or directly electrically coupled to the other element, layer, region, or component, or there may be one or more intervening elements, layers, regions, or components. One or more intervening components may include switches, resistors, capacitors, etc. In describing embodiments, unless explicitly described as being directly connected, the expression of connection indicates electrical connection, and "directly connected / directly coupled" or "directly on..." means that one component is directly connected or coupled to another component or directly on another component without intermediate components.

[0083] In addition, in this specification, when a part of a layer, film, zone, plate, etc. is formed on another part, the formation direction is not limited to the upward direction, but includes forming the part on the side surface or in the downward direction. On the contrary, when a part of a layer, film, zone, plate, etc. is formed "under" another part, this includes not only the case where the part is "directly under" another part, but also the case where there is another part between the part and the other part. At the same time, other expressions describing the relationship between parts, such as "between" and "directly between" or "adjacent to" and "directly adjacent to", can be similarly interpreted. 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 there may also be one or more intervening elements or layers.

[0084] For the purposes of this disclosure, when expressions such as "at least one of," or "any one of," or "one or more of," follow an element of a list, they modify the elements of the entire list rather than the individual elements of the list. For example, "at least one of X, Y, and Z," and "at least one selected from the group consisting of X, Y, and Z" may be interpreted as any combination of only X, only Y, only Z, or any combination of two or more of X, Y, and Z (such as, for example, XYZ, XYY, YZ, and XZ, or any variation thereof). Similarly, the expression "at least one of A and B" may include A, B, or A and B. As used herein, "or" generally means "and / or," and 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" may include A, B, or A and B.

[0085] It will be understood that, although the terms "first", "second", "third", etc. can be used in this article 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 do not correspond to a specific order, position or priority, but are only used to distinguish an element, member, component, region, area, layer, section or part from another element, member, component, region, area, layer, section or part. Therefore, without departing from the spirit and scope of the present disclosure, the first element, first component, first area, first layer or first section described below can be referred to as the second element, second component, second area, second layer or second section. Describing an element as a "first" element may not require or imply the presence of a second element or other elements. The terms "first", "second", etc. may also be used in this article to distinguish between different categories or different groups of elements. For simplicity, the terms "first", "second", etc. may respectively represent "first category (or first group)", "second category (or second group)", etc.

[0086] In the example, the x-axis, y-axis and / or z-axis are not limited to the three axes of the rectangular coordinate system, and can be interpreted in a broader sense. For example, the x-axis, y-axis and z-axis can be perpendicular to each other, or can represent different directions that are not perpendicular to each other. The same description applies to the first direction, the second direction and / or the third direction.

[0087] The terms used herein are for the purpose of describing embodiments only 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, and the plural forms are intended to include the singular forms as well, unless the context clearly indicates otherwise. It will also be understood that when used in this specification, the terms "comprises", "comprising", "have", "having", "includes" and "including" specify the presence of the features, wholes, steps, operations, elements and / or parts described, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, parts and / or combinations thereof.

[0088] When one or more embodiments can be implemented differently, the process order different from the described order can be performed. For example, two processes described in succession can be performed substantially at the same time, or in the reverse order of the described order.

[0089] As used herein, the terms "substantially", "about", "approximately" and similar terms are used as approximate terms rather than as terms of degree, and are intended to explain the inherent deviation of the measured or calculated values ​​that will be recognized by those of ordinary skill in the art. For example, "substantially" can include a range of + / -5% of the corresponding value. In view of the measurement discussed and the errors associated with the measurement of a specific amount (i.e., the limitations of the measurement system), as used herein, "about" or "approximately" includes the values ​​​​stated and means within the acceptable deviation range of the specific value determined by those of ordinary skill in the art. For example, "about" can mean within one or more standard deviations, or within ± 30%, ± 20%, ± 10%, ± 5% of the values ​​​​stated. In addition, "may" used in describing embodiments of the present disclosure means "one or more embodiments of the present disclosure".

[0090] The term "part" or "unit" refers to a software component or a hardware component that performs a corresponding function. The hardware component may include, for example, a field programmable gate array (FPGA) or an application specific integrated circuit (ASIC). A software component may refer to executable code in an addressable storage medium and / or data used by the executable code. Therefore, a software component may be, for example, an object-oriented software component, a class component, and a task component, and may include a process, a function, a property, a program, a subroutine, a program code segment, a driver, firmware, microcode, a circuit, data, a database, a data structure, a table, an array, or a variable.

[0091] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those skilled 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.

[0092] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0093] Figure 1A is a perspective view of an electronic device 1000 according to one or more embodiments of the present disclosure. Figure 1B is a rear perspective view of an electronic device 1000 according to one or more embodiments of the present disclosure. Figure 2 is a perspective view of an electronic device 1000 - 1 according to one or more embodiments of the present disclosure.

[0094] refer to Figure 1A and Figure 1B , the electronic device 1000 may be a display device activated according to an electrical signal. For example, the electronic device 1000 may display an image and may sense an externally applied input. The external input may be an input by a user. The external input may include various types of inputs, such as input by a body part of a user or input by an input device.

[0095] 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. 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. Each of the first display panel DP1 and the second display panel DP2 may be coupled to a housing HUS.

[0096] The area of ​​the second display panel DP2 may be smaller than that of the first display panel DP1. If the electronic device 1000 is unfolded, the first display panel DP1 may have a plane substantially parallel to the first direction DR1 and the second direction DR2. The thickness direction of the electronic device 1000 may be parallel to a third direction DR3 intersecting the first direction DR1 and the second direction DR2. Therefore, the front surface (or upper surface) and the rear surface (or lower surface) of the components constituting the electronic device 1000 may be defined based on the third direction DR3.

[0097] The first display panel DP1 may include a folding area FA that can be folded and unfolded and a plurality of non-folding areas NFA1 and NFA2 that are spaced apart from each other, and the folding area FA is interposed between the plurality of non-folding areas NFA1 and NFA2. The second display panel DP2 may overlap any 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.

[0098] The display direction of the first image IM1a displayed on a portion of the first display panel DP1 (e.g., in the first non-folding area NFA1) and the display direction of the second image IM2a displayed on the second display panel DP2 may be opposite to each other. 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 (see Figure 1B )superior.

[0099] In one or more embodiments of the present disclosure, the folding area FA may be bent based on a folding axis extending in a direction parallel to the long side of the electronic device 1000 (e.g., in a direction parallel to the second direction DR2). In a state where the electronic device 1000 is folded, the folding area FA has a curvature (e.g., a predetermined curvature) and a radius of curvature (e.g., a predetermined radius of curvature). The first non-folding area NFA1 and the second non-folding area NFA2 face each other, or face away from each other, and the electronic device 1000 may be folded inwardly so that the first display panel DP1 is not exposed to the outside. That is, the first display panel DP1 may be folded inwardly.

[0100] In one or more embodiments of the present disclosure, the first display panel DP1 may be folded outwardly to be exposed to the outside. In one or more embodiments of the present disclosure, the electronic device 1000 may selectively operate between folding inwardly from an unfolded state and folding outwardly from an unfolded state, but the present disclosure is not limited thereto.

[0101] Figure 1AIt is shown that 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 corresponding to the multiple folding axes may be defined in the electronic device 1000-1, and the electronic device 1000 may be folded inward or outward from the unfolded state in each of the multiple folding areas.

[0102] According to one or more embodiments of the present disclosure, at least one of the first display panel DP1 and the second display panel DP2 can sense input by the pen PN even if a digitizer is not included. Therefore, since the digitizer for sensing the pen PN is omitted, the thickness and weight of the electronic device 1000 can be reduced, and the flexibility of the electronic device 1000, which may be undesirably affected by the addition of the digitizer, can be increased. Therefore, not only the first display panel DP1 but also the second display panel DP2 can be designed to sense the pen PN.

[0103] refer to Figure 2 The electronic device 1000-1 may be a mobile phone or a tablet, and is not particularly limited thereto. The electronic device 1000-1 may include a display panel DP.

[0104] In one or more embodiments of the present disclosure, the display panel DP may sense external input. According to one or more embodiments of the present disclosure, although the digitizer is not included / omitted, the display panel DP may sense input by the pen PN. Therefore, since the digitizer for sensing the pen PN is omitted, the thickness and weight of the electronic device 1000 or 1000-1 do not need to be increased due to the addition of the digitizer.

[0105] Figure 1A and Figure 1B A foldable electronic device 1000 is shown, and Figure 2 A tablet-type electronic device 1000 - 1 is shown, but the present disclosure is not limited thereto. For example, the description given below may be applied to various electronic devices such as a rollable electronic device, a slidable electronic device, and a stretchable electronic device.

[0106] Figure 3 1 is a schematic cross-sectional view of a display panel DP according to one or more embodiments of the present disclosure. The display panel DP may be the first display panel DP1 or the second display panel DP2 of FIG. 1 .

[0107] refer to Figure 3 , the display panel DP may include a display layer 100 and a sensor layer 200. In one or more embodiments of the present disclosure, the display layer 100 may be defined as a display panel, and the sensor layer 200 may be defined as an input sensor.

[0108] The display layer 100 may be configured to substantially generate an image. The display layer 100 may be a light-emitting display layer. For example, the display layer 100 may include 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.

[0109] The base layer 110 may be a member providing a base surface on which the circuit layer 120 is positioned. 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 is not particularly limited thereto.

[0110] The circuit layer 120 may be located on the base layer 110 (as used herein, "located on" may mean "above"). The circuit layer 120 may include an insulating layer, a semiconductor pattern, a conductive pattern, a signal line, etc. The insulating layer, the semiconductor layer, and the conductive layer may be formed on the base layer 110 by coating, deposition, etc., and the circuit layer 120 may be formed by selectively patterning the insulating layer, the semiconductor layer, and the conductive layer by multiple photolithography processes. In one or more embodiments of the present disclosure, the circuit layer 120 may be defined as a driving element layer.

[0111] The light emitting element layer 130 may be located 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.

[0112] The encapsulation layer 140 may be located 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.

[0113] The sensor layer 200 may be located on the display layer 100. The sensor layer 200 may sense external input. The sensor layer 200 may be an integrated sensor continuously formed during a manufacturing process of the display layer 100, or 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 for sensing input coordinates, an input sensing layer, an input sensing panel, or an electronic device.

[0114] In one or more embodiments of the present disclosure, a portion of the sensor layer 200 may be located on the display layer 100, and a portion of the sensor layer 200 may be located below the display layer 100. For example, Figure 5The first conductive layer 202 and the sensing insulating layer (which may also be referred to as the second insulating layer) 203 shown in FIG. 1 may be located below the display layer 100, rather than above the display layer 100. In this case, the second conductive layer 204 and the cover insulating layer 205 may be located on the base insulating layer (which may also be referred to as the first insulating layer) 201. The first conductive layer 202 may be located below the base layer 110, and the sensing insulating layer 203 may be located below the first conductive layer 202.

[0115] According to one or more embodiments of the present disclosure, the sensor layer 200 may sense not only inputs made by a body part of a user, but also inputs made by an input device that generates a magnetic field at a resonant frequency (e.g., a predetermined resonant frequency). In one or more embodiments of the present disclosure, the input device that generates a magnetic field at a resonant frequency (e.g., a predetermined resonant frequency) may be referred to as a pen, an input pen, a magnetic pen, a stylus, or an electromagnetic resonance pen.

[0116] Figure 4 The operation of the electronic device 1000 according to one or more embodiments of the present disclosure is described.

[0117] refer to Figure 4 , 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 supply circuit 1000P.

[0118] The sensor layer 200 may sense a first input 2000 or a second input 3000 applied from the outside. Each of the first input 2000 and the second input 3000 may be an input device capable of providing a capacitance change of the sensor layer 200, or an input device capable of causing an induced current in the sensor layer 200. For example, the first input 2000 may be an input device capable of providing an electric charge. The second input 3000 may be an input by a pen PN or an RFIC tag. For example, the pen PN may be a passive pen or an active pen.

[0119] In one or more embodiments of the present disclosure, the pen PN may be a device that generates a magnetic field at a resonant frequency (e.g., a predetermined resonant frequency). The pen PN may be configured to transmit an output signal based on an electromagnetic resonance method. The pen PN may be referred to as an input pen, a magnetic pen, a stylus pen, or an electromagnetic resonance pen.

[0120] The pen PN may include an RLC resonant circuit, and the RLC resonant circuit may include an inductor L and a capacitor C. In one or more embodiments 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, but the present disclosure is not particularly limited thereto.

[0121] The inductor L generates a current through a magnetic field formed in the sensor layer 200. However, the present disclosure is not particularly limited thereto. For example, if the pen PN operates as an active type, the pen PN can generate a current even if the pen PN does not receive a magnetic field from the outside. The generated current is transmitted to the capacitor C. The capacitor C is charged with the current input from the inductor L, and discharges the charged current to the inductor L. Hereinafter, the inductor L may emit a magnetic field at a resonant frequency. The induced current may flow in the sensor layer 200 due to the magnetic field emitted by the pen PN, and the induced current may be transmitted to the sensor driver 200C as a received signal (or a sensing signal).

[0122] The main driver 1000C may control the overall operation of the electronic device 1000. For example, the main driver 1000C may 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.

[0123] The display driver 100C may drive the display layer 100. The display driver 100C may receive image data and control signals from the main driver 1000C. The control signals may include various signals. For example, the control signals may include an input vertical synchronization signal, an input horizontal synchronization signal, a main clock signal, a data enable signal, and the like.

[0124] The sensor driver 200C may drive the sensor layer 200. The sensor driver 200C may receive a control signal from the main driver 1000C. The control signal may include a clock signal of the sensor driver 200C. In addition, the control signal may further include a mode determination signal that determines a driving mode of the sensor driver 200C and the sensor layer 200.

[0125] The sensor driver 200C may be implemented as 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 area (e.g., a predetermined area) of the display panel DP, or may be mounted on a separate printed circuit board by a chip on film (COF) method so as to be electrically connected to the sensor layer 200.

[0126] The sensor driver 200C may selectively operate the sensor layer 200 in a first mode or a second mode. For example, the first mode may be a mode for sensing a touch input (e.g., the first input 2000). The second mode may be a mode for sensing a pen input (e.g., the second input 3000). The first mode may be referred to as a touch sensing mode (e.g., a pen standby mode), and the second mode may be referred to as a pen sensing mode.

[0127] The conversion between the first mode and the second mode can be performed in various ways. For example, the sensor driver 200C and the sensor layer 200 can be driven in the first mode and the second mode in time division, and the first input 2000 and the second input 3000 can be sensed. Alternatively, the conversion between the first mode and the second mode can occur due to the user's selection or corresponding action, or any one of the first mode or the second mode can be activated or disabled, or converted to another mode by activation or deactivation of the corresponding application. Alternatively, when the sensor driver 200C and the sensor layer 200 operate alternately in the first mode and the second mode, if the first input 2000 is sensed, the first mode can be maintained, or if the second input 3000 is sensed, the second mode can be maintained.

[0128] The sensor driver 200C may calculate the input coordinate information based on the signal received from the sensor layer 200, and may provide a coordinate signal having 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 may operate the display driver 100C so that a new application image is displayed on the display layer 100.

[0129] The power supply circuit 1000P may include a power management integrated circuit (PMIC). The power supply 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 limited to the above examples.

In other words, a portion of the semiconductor pattern may be the active region AL of the transistor 100PC, another portion thereof may be the source region SC or the drain region DR of the transistor 100PC, and another portion thereof may be a connecting electrode or a connecting signal line SCL.

The non-display area may be located outside the display area (eg, in a plan view).

[0163] 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 ("first electrodes" may also be referred to as "first sensing electrodes", and "second electrodes" may also be referred to as "second sensing electrodes") located in a sensing region 200A.

[0164] The first electrodes 210 may cross the second electrodes 220, respectively. Each of the first electrodes 210 may extend along the second direction DR2, and the first electrodes 210 may be arranged to be spaced apart from each other in the first direction DR1. Each of the second electrodes 220 may extend along the first direction DR1, and the second electrodes 220 may be arranged to be spaced apart from each other in the second direction DR2. The sensing unit SU of the sensor layer 200 may be a region where one of the first electrodes 210 and one of the second electrodes 220 cross each other. Figure 6 Six first electrodes 210 , ten second electrodes 220 , and sixty sensing units SU are illustrated, but the number of the first electrodes 210 and the number of the second electrodes 220 are not limited thereto.

[0165] refer to Figure 6 and Figure 7 , each of the first electrodes 210 may include first separation electrodes 210-dv1 and 210-dv2. The first separation electrodes 210-dv1 and 210-dv2 may extend along the second direction DR2 and may be spaced apart from each other in the first direction DR1. The first separation electrodes 210-dv1 and 210-dv2 may have a linearly symmetrical shape with respect to a line extending in the second direction DR2 (e.g., may be symmetrical).

[0166] Each of the second electrodes 220 may include second separation electrodes 220-dv1 and 220-dv2. The second electrodes 220 may extend along the first direction DR1 and may be spaced apart from each other in the second direction DR2. The second separation electrodes 220-dv1 and 220-dv2 may have a linearly symmetrical shape with respect to a line extending in the first direction DR1 (eg, may be symmetrical).

[0167] refer to Figure 7 , Fig. 8A , Figure 8B and Fig. 9 Each of the second separation electrodes 220-dv1 and 220-dv2 may include a bridge pattern 221 and two sensing patterns 222 located in the sensing unit SU. The bridge pattern 221 may be located on a layer different from that of the sensing pattern 222, and the bridge pattern 221 and the sensing pattern 222 may be electrically connected to each other through the first contact hole CNa. Figure 5 Similar to the contact hole CNT-4 in FIG. 1 , the contact holes including the first contact hole CNa described below may pass through the sensing insulating layer 203. For example, the bridge pattern 221 may be included in the first conductive layer 202SU, and the sensing pattern 222 and the first separation electrodes 210-dv1 and 210-dv2 may be included in the second conductive layer 204SU. The first conductive layer 202SU may be included in Figure 5 The first conductive layer 202, and the second conductive layer 204SU may include Figure 5 The conductive pattern and / or the electrode may be formed from the conductive layer by a photolithography process.

[0168] refer to Figure 6 , each of the third electrodes 230 may extend along the second direction DR2, and the third electrodes 230 may be arranged to be spaced apart from each other in the first direction DR1. In one or more embodiments of the present disclosure, each of the third electrodes 230 may include a plurality of first auxiliary electrodes 230s ("first auxiliary electrodes" may also be referred to as "first electrodes") connected in parallel to each other. The number of the first auxiliary electrodes 230s included in each of the third electrodes 230 may vary. 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 decreases, and therefore, power efficiency and sensing sensitivity may be improved. On the contrary, as the number of the first auxiliary electrodes 230s included in each of the third electrodes 230 decreases, the annular coil pattern formed by using the third electrode 230 may be implemented in a more diverse form.

[0169] Figure 6It is shown that one third electrode 230 includes two first auxiliary electrodes 230s, but the present disclosure is not particularly limited thereto. In one or more embodiments of the present disclosure, each of the third electrodes 230 may include one first auxiliary electrode 230s. Figure 6 , the first auxiliary electrode 230s may be positioned in a one-to-one correspondence with the first electrode 210. Therefore, a portion of one first auxiliary electrode 230s may be positioned Figure 6 and Figure 7 In one sensing unit SU shown in FIG. In one or more embodiments of the present disclosure, the third electrode 230 may include three first auxiliary electrodes 230s.

[0170] refer to Figures 6 to 9 , a coupling capacitor may be defined between one first electrode 210 and one first auxiliary electrode 230s. In this case, the induced current generated during pen sensing may be transmitted from the first auxiliary electrode 230s to the first electrode 210 through the coupling capacitor. That is, the first auxiliary electrode 230s may be used to supplement the signal transmitted from the first electrode 210 to the sensor driver 200C. Therefore, if the phase of the signal induced in the first auxiliary electrode 230s matches the phase of the signal induced in the first electrode 210, the maximum effect may be obtained. Therefore, (for example, in a plan view) the center of each of the first electrodes 210 in the first direction DR1 and the center of each of the first auxiliary electrodes 230s in the first direction DR1 may overlap each other.

[0171] In one or more embodiments of the present disclosure, since one third electrode 230 includes two first auxiliary electrodes 230s, one third electrode 230 may correspond to (or overlap) two first electrodes 210. Therefore, the number of third electrodes 230 included in the sensor layer 200 may be less than the number of first electrodes 210. For example, the number of first electrodes 210 may be equal to a value obtained by multiplying the number of third electrodes 230 included in the sensor layer 200 by the number of first auxiliary electrodes 230s included in each of the third electrodes 230. Figure 6 , the number of the first electrodes 210 may be six, the number of the third electrodes 230 may be three, and the number of the first auxiliary electrodes 230 s included in each of the third electrodes 230 may be two.

[0172] The fourth electrode 240 may be arranged along the second direction DR2, and the fourth electrode 240 may extend along the first direction DR1. In one or more embodiments of the present disclosure, the fourth electrode 240 may be divided into two groups. The fourth electrodes 240 belonging to the same group may be connected to the same trace (or the same connection line). The fourth electrode 240 divided into two groups may be referred to as second auxiliary electrodes 240s1 and 240s2 ("second auxiliary electrode" may also be referred to as "second electrode"). The second auxiliary electrodes 240s1 and 240s2 may be referred to as 2-1st auxiliary electrodes 240s1 and 2-2nd auxiliary electrodes 240s2. The 2-1st auxiliary electrode 240s1 and the 2-2nd auxiliary electrode 240s2 are connected to different corresponding fourth traces 240t-1 and 240t-2. The 2-1st auxiliary electrode 240s1 is connected to the same fourth trace 240t-1, and the 2-2nd auxiliary electrode 240s2 is connected to the same fourth trace 240t-2.

[0173] In one or more embodiments of the present disclosure, the fourth electrode 240 may be divided into two or more groups. If the fourth electrode 240 is connected to different traces, the fourth electrode 240 may be divided into different groups. The fourth electrodes 240 divided into different groups may receive synchronization signals or the same signal through different fourth traces. In one or more embodiments of the present disclosure, the fourth electrode 240 may be a group. The fourth electrode 240 may be connected to one fourth trace.

[0174] In one or more embodiments of the present disclosure, the fourth electrode 240 may be divided into three groups, two of which may be located on the left side of the sensing region 200A, and one of which may be located on the right side of the sensing region 200A.

[0175] In one or more embodiments of the present disclosure, the fourth electrode 240 may be divided into four groups. Two of the four groups may be located on the left side of the sensing region 200A, and two of the four groups may be located on the right side of the sensing region 200A. In the second direction DR2, the two groups located on the left side may be located farther from or closer to the second pad PD2 or the third pad PD3 than the two groups located on the right side. In the second direction DR2, the two groups located on the left side and the two groups located on the right side may be in a zigzag shape from the second pad PD2 or the third pad PD3.

[0176] The wiring directions of the 2-1st auxiliary electrode 240s1 and the 2-2nd auxiliary electrode 240s2 may be different from each other. In the present specification, the expression that the wiring directions are different from each other means that the connection positions between the electrodes and the traces are different from each other. For example, the first connection position of the fourth trace 240t-1 electrically connected to the 2-1st auxiliary electrode 240s1 and the second connection position of the fourth trace 240t-2 electrically connected to the 2-2nd auxiliary electrode 240s2 may be different from each other. The first connection position may be at the left end of the 2-1st auxiliary electrode 240s1, and the second connection position may be at the right end of the 2-2nd auxiliary electrode 240s2.

[0177] Figure 6 It is shown that five 2-1st auxiliary electrodes 240s1 are electrically connected to each other, and five 2-2nd auxiliary electrodes 240s2 are electrically connected to each other. In one or more embodiments of the present disclosure, the number of 2-1st auxiliary electrodes 240s1 and the number of 2-2nd auxiliary electrodes 240s2 may be different from each other.

[0178] In one or more embodiments of the present disclosure, as the number of the 2-1st auxiliary electrodes 240s1 increases and the number of the 2-2nd auxiliary electrodes 240s2 increases, an effect of increasing the area of ​​the electrode (e.g., a single continuous electrode) in which the electrode is electrically defined as one can occur. In addition, the resistance of the electrode electrically defined as one can be reduced, thereby improving the second input 3000 (see Figure 4 )’s sensing sensitivity.

[0179] refer to Figures 6 to 9 , 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 during pen sensing may be transmitted from the second auxiliary electrode 240s1 or 240s2 to the second electrode 220 through the coupling capacitor. That is, the second auxiliary electrode 240s1 or 240s2 may be used to supplement the signal transmitted from the second electrode 220 to the sensor driver 200C. Therefore, if the phase of the signal induced in the second auxiliary electrode 240s1 or 240s2 matches the phase of the signal induced in the second electrode 220, the maximum effect may be obtained. Therefore, (for example, in a plan view) the center of each of the second electrodes 220 in the second direction DR2 and the center of each of the second auxiliary electrodes 240s1 and 240s2 in the second direction DR2 may overlap each other.

[0180] refer to Figure 7 , Fig. 8A and Figure 8B, each of the first auxiliary electrodes 230s may include a 3-1st pattern 231 and a 3-2nd pattern 232. Meanwhile, the terms "3-1st pattern 231" and "3-2nd pattern 232" are used only for the purpose of distinguishing them from other patterns. If the 3-1st pattern 231 is defined as a first pattern, the 3-2nd pattern 232 may be defined as a second pattern.

[0181] The 3-1st pattern 231 and the 3-2nd pattern 232 may be located on different corresponding layers and may be electrically connected to each other through the second contact hole CNb. The 3-1st pattern 231 may be included in the first conductive layer 202SU, and the 3-2nd pattern 232 may be included in the second conductive layer 204SU.

[0182] In one or more embodiments of the present disclosure, any one of the 3-1st pattern 231 and the 3-2nd pattern 232 may be omitted. In one or more embodiments of the present disclosure, although the 3-1st pattern 231 and the 3-2nd pattern 232 are positioned, they may not be electrically connected to each other. In this case, one of the 3-1st pattern 231 and the 3-2nd pattern 232 may correspond to the first auxiliary electrode 230s, and the other thereof may correspond to a dummy electrode (or floating electrode).

[0183] In one or more embodiments of the present disclosure, a portion of the 3-1st pattern 231 may overlap a portion of each of the first separation electrodes 210-dv1 and 210-dv2. Therefore, a coupling capacitor may be disposed (or formed) between the first electrode 210 and the third electrode 230. An opening 231-OP may be defined in the 3-1st pattern 231. The bridge pattern 221 described above and the 4-2nd pattern 242 to be described later may be located in the opening 231-OP.

[0184] refer to Figure 7 , Fig. 8A and Figure 8B , each of the second auxiliary electrodes 240s1 and 240s2 may include two 4-1st patterns 241, one 4-2nd pattern 242, and two 4-3rd patterns 243 located in the sensing unit SU. Meanwhile, the terms "4-1st pattern 241, 4-2nd pattern 242, and 4-3rd pattern 243" are used only for the purpose of distinguishing them from other patterns. If the 4-1st pattern 241 is defined as the first pattern, the 4-2nd pattern 242 may be defined as the second pattern, and the 4-3rd pattern 243 may be defined as the third pattern.

[0185] The 4-1st pattern 241 and the 4-2nd pattern 242 may be located on the same layer, and the 4-3rd pattern 243 may be located on a different layer from the 4-1st pattern 241 and the 4-2nd pattern 242. The 4-1st pattern 241 and the 4-3rd pattern 243 may be electrically connected to each other through the third contact hole CNc. The 4-2nd pattern 242 and the 4-3rd pattern 243 may be electrically connected to each other through the fourth contact hole CNd. The 4-1st pattern 241 and the 4-2nd pattern 242 may be included in the first conductive layer 202SU, and the 4-3rd pattern 243 may be included in the second conductive layer 204SU.

[0186] refer to Figure 7 , Fig. 8A and Figure 8B , a portion of the 4-1st pattern 241 may overlap the sensing pattern 222 of each of the second separation electrodes 220 - dv1 and 220 - dv2. Therefore, a coupling capacitor may be defined (or provided, formed) between the second electrode 220 and the fourth electrode 240.

[0187] In one or more embodiments of the present disclosure, the first conductive layer 202SU may further include a dummy pattern DMP. Each of the dummy patterns DMP may be electrically floating or electrically grounded. Some of the dummy patterns DMP may overlap with the first separation electrodes 210-dv1 and 210-dv2, and other of the dummy patterns DMP may overlap with the sensing pattern 222. In one or more embodiments of the present disclosure, the dummy pattern DMP may be omitted. In one or more embodiments of the present disclosure, the dummy pattern DMP may be electrically connected to the overlapping electrodes among the first separation electrodes 210-dv1 and 210-dv2, so that the sensing sensitivity may be further improved.

[0188] refer to Figure 6 , the sensor layer 200 may further include a plurality of first traces 210t located in the peripheral area 200NA and a plurality of first pads PD1 connected to the first traces 210t in a one-to-one correspondence, and may further include a plurality of second traces 220t and a plurality of second pads PD2 connected to the second traces 220t in a one-to-one correspondence. The traces including the first traces 210t and the second traces 220t described below may also be defined as connection lines or lines.

[0189] The first trace 210t may be electrically connected to the first electrode 210 in a one-to-one correspondence. Two first separation electrodes 210-dv1 and 210-dv2 included in one first electrode 210 may be connected to one of the first traces 210t. Each of the first traces 210t may include a plurality of branches for connecting to the two first separation electrodes 210-dv1 and 210-dv2.

[0190] The second trace 220t may be electrically connected to the second electrode 220 in a one-to-one correspondence. Two second separation electrodes 220-dv1 and 220-dv2 included in one second electrode 220 may be connected to one of the second traces 220t.

[0191] refer to Figure 6 , the sensor layer 200 may further include a third trace (e.g., a peripheral trace, or simply referred to as a trace or a connection line in the claims) 230rt1 located in the peripheral area 200NA, two third pads PD3 connected to respective ends of the third trace 230rt1, two fourth traces 240t-1 and 240t-2, two fourth pads PD4 connected to the fourth traces 240t-1 and 240t-2, respectively, a fifth trace 230rt2, and fifth pads PD5 connected to the fifth trace 230rt2 in a one-to-one correspondence. In one or more embodiments, the fifth pad PD5 may be positioned closer to one of the third pads PD3 (e.g., the third pad PD3 on the left side) than another of the third pads PD3 (e.g., the third pad PD3 on the right side).

[0192] 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 along the first direction DR1 and electrically connected to one end of the third electrode 230, a second line portion 232t extending along the second direction DR2 from a first end of the first line portion 231t, and a third line portion 233t extending along the second direction DR2 from a second end of the first line portion 231t. One end of the second line portion 232t is connected to the third pads PD3 (e.g., one of the third pads PD3), and one end of the third line portion 233t is connected to the third pads PD3 (e.g., another of the third pads PD3).

[0193] The fifth trace lines 230rt2 may be connected to the third electrodes 230 in a one-to-one correspondence. That is, the number of the fifth trace lines 230rt2 may correspond to the number of the third electrodes 230. Figure 6 Three fifth traces 230rt2 are shown as an example.

[0194] The fourth traces 240t-1 and 240t-2 may be spaced apart from each other, with the sensing region 200A interposed therebetween. One end of each of the 2-1st auxiliary electrodes 240s1 may be connected to one fourth trace 240t-1. One end of each of the 2-2nd auxiliary electrodes 240s2 may be connected to another fourth trace 240t-2.

[0195] refer to Figures 6 to 9 Describes in detail the Figure 5 The sensor layer 200 is formed of a first conductive layer 202 and a second conductive layer 204 , but the present disclosure is not limited thereto.

[0197] Fig. 10A yes Fig. 8A An enlarged plan view of the area AA' shown in FIG. Fig. 10B yes Figure 8B An enlarged plan view of the area BB' shown in FIG.

[0198] refer to Fig. 8A , Figure 8B , Fig. 10A and Fig. 10B, each of the first electrode 210, the second electrode 220, the third electrode 230, the fourth electrode 240, and the dummy pattern DMP may have a grid structure. Each of the grid structures may include a plurality of grid lines. Each of the plurality of grid lines may have a straight line shape extending in a corresponding direction (e.g., a predetermined direction) and may be connected to each other. An opening where no grid structure is positioned may be defined (set 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.

However, the extending directions of the grid lines constituting the grid structure are not particularly limited to Fig. 10A and Fig. 10B For example, the grid structure may include only grid lines extending 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 crossing direction CDR1, and the second crossing direction CDR2. That is, the grid structure may be changed in various forms.

[0200] Fig.11 A sensor driver 200C (see FIG. Figure 4 ) operation.

[0201] refer to Figure 4 and Fig.11 , the sensor driver 200C may be configured to be selectively driven in any one of a first operation mode DMD1 , a second operation mode DMD2 , and a third operation mode DMD3 .

[0202] The first operation mode DMD1 may be referred to as a touch standby and pen standby mode, the second operation mode DMD2 may be referred to as a touch activation and pen standby mode, and the third operation mode DMD3 may be referred to as a pen activation mode. The first operation mode DMD1 may be a mode of waiting for the first input 2000 and the second input 3000. Here, the standby mode means "detecting the occurrence of the first input 2000 or the second input 3000". The second operation mode DMD2 may be a mode of sensing information of the first input 2000 and waiting for the second input 3000 after sensing the occurrence of the first input 2000. "Sensing information of the first input 2000" means "calculating coordinate information of the first input 2000". Unlike the second operation mode DMD2, the third operation mode DMD3 may be a mode of sensing information of the second input 3000.

[0203] In one or more embodiments of the present disclosure, the sensor driver 200C may first operate in the first operating mode DMD1. If the occurrence of the first input 2000 is sensed in the first operating mode DMD1, the sensor driver 200C may switch (or change) to the second operating mode DMD2. Alternatively, if the occurrence of the second input 3000 is sensed in the first operating mode DMD1, the sensor driver 200C may switch (or change) to the third operating mode DMD3.

[0204] In one or more embodiments of the present disclosure, if the occurrence of the second input 3000 is sensed in the second operating mode DMD2, the sensor driver 200C may switch to the third operating mode DMD3. If the first input 2000 is released in the second operating mode DMD2 (or if the occurrence of the first input 2000 is no longer sensed), the sensor driver 200C may switch to the first operating mode DMD1. If the second input 3000 is released in the third operating mode DMD3 (or the occurrence of the second input 3000 is no longer sensed), the sensor driver 200C may switch to the first operating mode DMD1.

[0205] Fig.12 A sensor driver 200C (see FIG. Figure 4 ) operation.

[0206] refer to Figure 4 , Fig.11 and Fig.12 , operations in the first operation mode DMD1 , the second operation mode DMD2 , and the third operation mode DMD3 are shown in sequence with time t.

[0207] 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 (see Figure 4 During the first mode MD1-d, the sensor layer 200 may be scan-driven to detect the first input 2000 (see Figure 4 ) occurs. Fig.12 It is shown that the sensor driver 200C operates in the first mode MD1 - d successively after the second mode MD2 - d , but the order is not limited thereto.

[0208] In the second operation 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 occurrence of the second input 3000. During the first mode MD1, the sensor layer 200 may be scan-driven to detect information of the first input 2000.

[0209] In the third operation 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 information of the second input 3000. In the third operation mode DMD3, the sensor driver 200C may not operate in the first mode MD1-d or MD1 until the second input 3000 is released (or the occurrence of the second input 3000 is no longer sensed).

[0210] Also refer to Figure 6 In the first mode MD1-d and the first mode MD1, both the third electrode 230 and the fourth electrode 240 may be grounded. Therefore, the touch noise may be reduced or prevented from entering through the third electrode 230 and the fourth electrode 240.

[0211] In the second mode MD2-d and the second mode MD2, the first end of each of the third electrode 230 and the fourth electrode 240 may be floated. In addition, in the second mode MD2-d and the second mode MD2, the other end of each of the third electrode 230 and the fourth electrode 240 may be grounded or floated. Therefore, by coupling the first electrode 210 and the third electrode 230 and by coupling the second electrode 220 and the fourth electrode 240, the compensation of the sensing signal may be improved or maximized.

[0212] Fig.13A The first mode according to one or more embodiments of the present disclosure has been described. Fig. 13B The first mode according to one or more embodiments of the present disclosure has been described.

[0213] refer to Fig.12 , Fig.13A and Fig. 13B The first mode MD1-d and the first mode MD1 may include a self-capacitance detection mode. The self-capacitance detection mode may include a first sub-section and a second sub-section. Fig.13A The operations in the first subsection are described, and Fig. 13B The operations in the second subsection are described.

[0214] The sensor driver 200C outputs driving signals Txs1 and Txs2 to the first electrode 210 and the second electrode 220 in the self-capacitance detection mode, and reads the changed signals after a period of time (e.g., a predetermined time). The sensor driver 200C can calculate the input coordinates by sensing the capacitance change of each of the first electrode 210 and the second electrode 220. Fig.13A , in the first sub-section, the sensor driver 200C may output a driving signal Txs1 to the first trace 210t. Fig. 13B , in the second subsection, the sensor driver 200C may output a driving signal Txs2 to the second trace 220t. In the first subsection, the sensor driver 200C may sense a signal changed from the driving signal Txs1 passing through the first trace 210t. In the second subsection, the sensor driver 200C may sense a signal changed from the driving signal Txs2 passing through the second trace 220t.

[0215] The third electrode 230 is electrically connected to the third and fifth traces 230rt1 and 230rt2, and the fourth electrode 240 is electrically connected to the fourth traces 240t-1 and 240t-2. In the self-capacitance detection mode, both the third and fourth electrodes 230 and 240 may be grounded. Therefore, noise may not enter through the third and fourth electrodes 230 and 240.

[0216] In one or more other embodiments of the present disclosure, a reference potential may be applied to the third electrode 230 and the fourth electrode 240. In one or more other embodiments of the present disclosure, a transmission signal and an in-phase signal may be applied to the third electrode 230 and the fourth electrode 240. In this case, noise may not enter through the third electrode 230 and the fourth electrode 240.

[0217] Fig.14 The first mode according to one or more embodiments of the present disclosure has been described.

[0218] refer to Figure 4 , Fig.12 and Fig.14 , the first mode MD1-d and the first mode MD1 may further include a mutual capacitance detection mode. Fig.14 Describes the mutual capacitance detection mode.

[0219] 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 first input 2000 by using a reception signal RX detected through the second electrode 220 (see Figure 4) coordinates. For example, the sensor driver 200C may be configured to calculate the input coordinates by sensing the mutual capacitance change between the first electrode 210 and the second electrode 220. In one or more embodiments of the present disclosure, the transmission signal TX may be sequentially provided to the second electrode 220, and the first input 2000 (see Figure 4 ) may be detected by using the reception signal RX detected through the first electrode 210. The conflicting driving methods described above may be alternately performed.

[0220] Fig.14 FIG. 2 shows that a transmission signal TX is provided to one first electrode 210, and a reception signal RX is output from a plurality of second electrodes 220. In order to clearly represent the signal, Fig.14 Only one first electrode 210 to which the transmission signal TX is provided is indicated by hatching / shading in FIG. The sensor driver 200C may detect the input coordinates of the first input 2000 by sensing a capacitance change between the first electrode 210 and each of the second electrodes 220 .

[0221] In the mutual capacitance detection mode, both the third electrode 230 and the fourth electrode 240 may be grounded. Therefore, noise may not enter through the third electrode 230 and the fourth electrode 240. In one or more other embodiments of the present disclosure, a reference potential may be applied to the third electrode 230 and the fourth electrode 240. In one or more other embodiments of the present disclosure, a transmission signal and an in-phase signal may be applied to the third electrode 230 and the fourth electrode 240. In this case, noise may not enter through the third electrode 230 and the fourth electrode 240.

[0222] In each of the first mode MD1-d and the first mode MD1, the sensor layer 200 may alternately repeat Fig.13A , Fig. 13B and Fig.14 However, this is only an example, and the present disclosure is not particularly limited thereto. For example, in each of the first mode MD1-d and the first mode MD1, the sensor layer 200 may only repeatedly perform Fig.14 Alternatively, in the first mode MD1-d, the sensor layer 200 may repeatedly perform Fig.13A , Fig. 13B and Fig.14 At least one of the operations described in the first mode MD1, and in the first mode MD1, the sensor layer 200 may alternately repeat Fig.13A , Fig. 13B and Fig.14 The operations described in .

[0223] Fig.15The second mode according to one or more embodiments of the present disclosure is described. Fig.16 Graphs showing waveforms of a first signal and a second signal according to one or more embodiments of the present disclosure are presented.

[0224] refer to Fig.12 and Fig.15 , the second mode MD2-d and the second mode MD2-d may include a charging driving mode and a pen sensing driving mode. In addition, the charging driving mode may include a searching charging driving mode and a tracking charging driving mode. Fig.15 The search charging drive mode is described.

[0225] refer to Fig.12 , Fig.15 and Fig.16 , in the charging drive mode, the sensor driver 200C may apply the first signal SG1 to one of the third pad PD3a and the fifth pad PD5a, and may apply the second signal SG2 to the other of the third pad PD3a and the fifth pad PD5a. The second signal SG2 may be an inverted signal of the first signal SG1. For example, the first signal SG1 may be a sinusoidal signal. Each of the first signal SG1 and the second signal SG2 may be a square wave signal. The relationship between the first signal SG1 and the second signal SG2 is not limited thereto. In one or more embodiments of the present disclosure, if the first signal SG1 is a square wave signal, the second signal SG2 may have a constant voltage (e.g., a predetermined constant voltage).

[0226] Since the first and second signals SG1 and SG2 are applied to at least two pads, the current RFS forms a current path from one pad to another pad. In addition, since the first and second signals SG1 and SG2 are sinusoidal signals having an anti-phase relationship with each other, the direction of the current RFS may change periodically.

[0227] Reference again Fig.15 , Fig.15 It is shown that the first signal SG1 is provided to a fifth pad PD5a connected to the third electrode 230 and the second signal SG2 is provided to a third pad PD3a connected to the third line portion 233t. The current RFS can flow along the 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 first line portion 231t, the third line portion 233t 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-d and the second mode MD2, the RLC resonant circuit of the pen PN can be charged by the magnetic field induced by the current path.

[0228] According to one or more embodiments of the present disclosure, the current path of the loop coil pattern may be implemented by a component included in the sensor layer 200. Therefore, the electronic device 1000 (see FIG. 1 ) may charge the pen PN by using the sensor layer 200. Therefore, since there is no need to separately add a component having a coil for charging the pen PN, the thickness and weight of the electronic device 1000 may not increase, and the flexibility of the electronic device 1000 may not deteriorate.

[0229] In the charging driving mode, the first electrode 210, the second electrode 220 and the fourth electrode 240 may be grounded, may have a constant voltage applied, or may be electrically floating. For example, the first electrode 210, the second electrode 220 and the fourth electrode 240 may float. In this case, the current RFS may not flow to the first electrode 210, the second electrode 220 and the fourth electrode 240.

[0230] Fig.17A is a table illustrating signals provided to a sensor layer according to one or more embodiments of the present disclosure. Fig. 17B is a table illustrating signals provided to a sensor layer according to one or more embodiments of the present disclosure. FIG. 17C to FIG. 17E The charging driving mode of the second mode according to one or more embodiments of the present disclosure is described. FIG. 17F to FIG. 17H The charging driving mode of the second mode according to one or more embodiments of the present disclosure is described.

[0231] refer to Figure 6 , Fig.15 , Fig.16 and Fig.17A , in each of the first time period t1, the second time period t2, the third time period t3, the fourth time period t4, the fifth time period t5, the sixth time period t6, the seventh time period t7, the eighth time period t8 and the ninth time period t9, Fig.17AThe table in shows the signal provided to the second line portion 232t, the signal provided to the first charging channel 230ch1, the second charging channel 230ch2, the third charging channel 230ch3, the fourth charging channel 230ch4, the fifth charging channel 230ch5, the sixth charging channel 230ch6, the seventh charging channel 230ch7, the eighth charging channel 230ch8, the ninth charging channel 230ch9 and the tenth charging channel 230ch10 (hereinafter referred to as the first charging channel 230ch1 to the tenth charging channel 230ch10) and the signal provided to the third line portion 233t, or shows the state of the third pad PD3 and the fifth pad PD5. The first charging channel 230ch1 to the tenth charging channel 230ch10 may be referred to as the first channel to the tenth channel, ten third electrode channels or ten channels. In this article, the charging channel may also be referred to as a "channel" or a "third electrode channel".

[0232] The first to tenth charging channels 230ch1 to 230ch10 may correspond to the third electrodes 230, respectively. Fig.15 Only three third electrodes 230 are shown as an example, but the sensor layer 200 may include more third electrodes 230 which may be described as first to tenth charging channels 230ch1 to 230ch10. That is, the first to tenth charging channels 230ch1 to 230ch10 may correspond one to one to the ten third electrodes 230.

[0233] In the search charging drive mode, Fig.17A The signals listed in the table shown in FIG. 1 are provided to the sensor layer 200 (see Fig.15 ). Therefore, since the position of the pen PN is not sensed, the first signal SG1 or the second signal SG2 may be provided to all channels included in the sensor layer 200. That is, the entire area of ​​the sensor layer 200 may be scanned in the search charge driving mode.

[0234] In the second mode, the charging driving mode and the pen sensing driving mode (see Fig. 20A ) may be repeated alternately. For example, after being charged and driven during the first time period t1, the sensor layer 200 may be operated in the pen sensing driving mode. During the second time period t2, if the pen PN is not sensed, the sensor layer 200 may be charged and driven again. Alternatively, if the pen PN is sensed, the sensor layer 200 may be driven in the tracking charging driving mode, which will be referred to below. Fig.18 , Fig.19A and Fig.19B Meanwhile, in one or more embodiments of the present disclosure, alternatively, even if the pen PN is sensed, the sensor layer 200 may be continuously driven in the search charge driving mode.

[0235] During the first time period t1, the second signal SG2 may be provided to the second line portion 232t, and the first signal SG1 may be provided to the third charging channel 230ch3 and the fourth charging channel 230ch4. During the first time period t1, the third line portion 233t to which neither the first signal SG1 nor the second signal SG2 is provided and all of the remaining charging channels 230ch1, 230ch2, 230ch5, 230ch6, 230ch7, 230ch8, 230ch9, and 230ch10 may be floated (FL). Fig.17A and Fig. 17B In the figure, “FL” means that the second line portion 232 t , the third line portion 233 t , and corresponding portions of the charging channels 230 ch1 to 230 ch10 are floating.

[0236] During the second time period t2, the second signal SG2 may be provided to the second line portion 232t and the first charging channel 230ch1, and the first signal SG1 may be provided to the fourth charging channel 230ch4 and the fifth charging channel 230ch5. Hereinafter, during the third time period t3, the fourth time period t4, the fifth time period t5, the sixth time period t6, the seventh time period t7, the eighth time period t8, and the ninth time period t9, the second signal SG2 and the first signal SG1 may be provided while being shifted by one channel.

[0237] In one or more embodiments of the present disclosure, except for the first time period t1 in which the second signal SG2 is provided to the second line portion 232t and except for the ninth time period t9 in which the first signal SG1 is provided to the third line portion 233t, the first signal SG1 may be provided to two channels, and the second signal SG2 may be provided to two channels. If the same signal is provided to a plurality of channels, an effect of reducing resistance may be obtained. Therefore, as resistance is reduced, power consumption of the sensor layer 200 may be reduced.

[0238] However, the number of channels to which the first signal SG1 and the second signal SG2 are provided is not particularly limited thereto. For example, the first signal SG1 may be provided to one channel and the second signal SG2 may be provided to another channel, or the first signal SG1 may be provided to three or more channels and the second signal SG2 may be provided to three or more other channels.

[0239] In one or more embodiments of the present disclosure, the operation of the second time period t2 may be omitted, and the operation of the third time period t3 may be performed immediately after the operation of the first time period t1. In addition, the operation of the eighth time period t8 may be omitted, and the operation of the ninth time period t9 may be performed immediately after the operation of the seventh time period t7.

[0240] In order to generate an electromagnetic field having an intensity equal to or exceeding a level (e.g., a predetermined level), it is desired that the floating charging channel should be located between the charging channels to which the second signal SG2 and the first signal SG1 are provided, or should be located between the second line portion 232t or the third line portion 233t and the charging channel. In one or more embodiments of the present disclosure, it is shown that the first charging channel 230ch1 and the second charging channel 230ch2 float between the second line portion 232t and the third charging channel 230ch3 in the first time period t1. That is, two floating channels (hereinafter referred to as gap channels) are shown to exist between the channel to which the first signal SG1 is provided and the channel to which the second signal SG2 is provided. As the number of gap channels increases, the intensity of the magnetic field formed by the current RFS can increase. Therefore, the number of gap channels can be increased according to the electronic device 1000 (see Figure 1A )'s usage conditions or the type of pen.

[0241] refer to Fig.15 , Fig.16 and Fig. 17B , in the first time period t1, the second signal SG2 may be provided to the second line portion 232t and the first charging channel 230ch1, and the first signal SG1 may be provided to the fourth charging channel 230ch4 and the fifth charging channel 230ch5. The third line portion 233t to which neither the first signal SG1 nor the second signal SG2 is provided and all of the remaining charging channels 230ch2, 230ch3, 230ch6, 230ch7, 230ch8, 230ch9, and 230ch10 may be floated. Hereinafter, during the second time period t2, the third time period t3, the fourth time period t4, the fifth time period t5, the sixth time period t6, the seventh time period t7, the eighth time period t8, and the ninth time period t9, the second signal SG2 and the first signal SG1 may be provided while being shifted by one channel.

[0242] At the first time period t1, the third trace 230rt1 may be driven by the second signal SG2, the third trace 230rt1 being connected to the first end of each of the third electrodes 230. In addition, a portion of the fifth trace 230rt2 may be driven by the second signal SG2, the portion of the fifth trace 230rt2 being connected to the second end of each of the first group of electrodes in the third electrodes 230. Another portion of the fifth trace 230rt2 may be driven by the first signal SG1 different from the second signal SG2, the other portion of the fifth trace 230rt2 being connected to the second end of each of the second group of electrodes in the third electrodes 230.

[0243] When with Fig.17AThe drive operation shown in Fig. 17B In the driving operation shown in , the operation in which the first signal SG1 or the second signal SG2 is provided only to the second line portion 232t or the third line portion 233t may be omitted. Therefore, the entire sensor layer 200 may be scanned during the first time period t1, the second time period t2, the third time period t3, the fourth time period t4, the fifth time period t5, the sixth time period t6, and the seventh time period t7. That is, according to Fig. 17B One or more embodiments described in Fig.17A In comparison, the entire sensor layer 200 may be scanned in a relatively short time.

[0244] FIG. 17C to FIG. 17E The operations in the first time period, the nth time period, and the last time period of a frame (or cycle) in the search charging driving mode are shown respectively. The nth time period may be Fig.17A The third time period t3 to the seventh time period t7 in one or more embodiments described in .

[0245] In order to allow the current RFS having the same strength to flow during the first time period, the nth time period, and the last time period, it is possible to Fig.17A The resistance of the second line portion 232t and the third line portion 233t is set based on the resistance of the third electrode 230 (e.g., the charging channels 230ch1 to 230ch10). In one or more embodiments of the present disclosure, each of the resistance of the second line portion 232t and the resistance of the third line portion 233t may be substantially equal to the resistance of one of the charging channels 230ch1 to 230ch10. In addition, the resistance of the second line portion 232t and the resistance of the third line portion 233t may be substantially equal to each other.

[0246] Because the third electrodes 230 define charging channels 230ch1 to 230ch10, respectively, each of the resistances of the second line portion 232t and the third line portion 233t may be substantially equal to the resistance of one of the third electrodes 230. The charging channels 230ch1 to 230ch10 may include a plurality of first auxiliary electrodes 230s electrically connected to each other or receiving the same signal. FIG. 17C to FIG. 17E It is shown that the charging channels 230ch1 to 230ch10 include two first auxiliary electrodes 230s.

[0247] The second line portion 232t and the third line portion 233t can be used as the third electrode 230, and the second line portion 232t and the third line portion 233t can produce substantially the same effect as having the third electrode 230 located in the peripheral area 200NA. For example, any one of the second line portion 232t and the third line portion 233t and any one of the third electrodes 230 can form a coil that induces an electromagnetic field. Although the pen PN is positioned in the peripheral area 200NA, the RLC resonant circuit of the pen PN can be charged. As the charging sensitivity of the pen PN in the peripheral area 200NA is improved, the signal-to-noise ratio of the pen PN in the peripheral area 200NA can be improved. This improvement in the signal-to-noise ratio of the pen PN can reduce the reference Figure 4 and Fig.11 In addition, the improvement of the signal-to-noise ratio of the pen PN can increase the detectable hovering height.

[0248] FIG. 17F to FIG. 17H The present invention shows a method for FIG. 17C to FIG. 17E The search charging driving mode is different from the search charging driving mode. FIG. 17F to FIG. 17H In the embodiment, the charging channels 230ch1 to 230ch10 may include one first auxiliary electrode 230s. Each of the resistance of the second line portion 232t and the resistance of the third line portion 233t may be substantially equal to the resistance of one first auxiliary electrode 230s. In addition, the resistance of the second line portion 232t may be less than the resistance of one of the first auxiliary electrodes 230s.

[0249] Fig.18 The second mode according to one or more embodiments of the present disclosure is described. Fig.19A is a table illustrating signals provided to a sensor layer according to one or more embodiments of the present disclosure. Fig.19B is a table illustrating signals provided to a sensor layer according to one or more embodiments of the present disclosure.

[0250] Fig.18 Describes the Track Charge Drive Mode. Fig.12 and Fig.18 , if the pen PN is sensed in the search charge driving mode, the sensor layer 200 may be driven in the tracking charge driving mode. For example, in the tracking charge driving mode, the sensor driver 200C may sequentially output the first signal SG1 and the second signal SG2 to an area overlapping with a point at which the pen PN is sensed, instead of sequentially outputting the first signal SG1 and the second signal SG2 to the entire area of ​​the sensor layer 200.

[0251] refer to Fig.18 and Fig.19A, indicating the position PN-dt of the pen PN sensed in the previous frame. Fig.19A It is shown that the pen PN is sensed in the area overlapping the fifth charging channel 230ch5 and the sixth charging channel 230ch6. In this case, the sensor driver 200C may provide the first signal SG1 and the second signal SG2 to the channel located in the area including the fifth charging channel 230ch5 and the sixth charging channel 230ch6.

[0252] In one or more embodiments of the present disclosure, the first signal SG1 and the second signal SG2 may be provided to a central loop around the position PN-dt of the pen PN of the previous frame and an area shifted by one channel from left to right based on the central loop. Fig.19A In the second time period t2 shown in FIG. 1 , the central loop may be provided (or formed) by the third charging channel 230ch3 and the fourth charging channel 230ch4 and the seventh charging channel 230ch7 and the eighth charging channel 230ch8 .

[0253] In the first time period t1, the second signal SG2 may be provided to the second charging channel 230ch2 and the third charging channel 230ch3, and the first signal SG1 may be provided to the sixth charging channel 230ch6 and the seventh charging channel 230ch7. In the second time period t2, the second signal SG2 may be provided to the third charging channel 230ch3 and the fourth charging channel 230ch4, and the first signal SG1 may be provided to the seventh charging channel 230ch7 and the eighth charging channel 230ch8. In the third time period t3, the second signal SG2 may be provided to the fourth charging channel 230ch4 and the fifth charging channel 230ch5, and the first signal SG1 may be provided to the eighth charging channel 230ch8 and the ninth charging channel 230ch9.

[0254] Therefore, after sensing the position PN-dt of the pen PN, the channel driven by charge in response to the position PN-dt of the pen PN of the previous frame may be limited. Therefore, since the channel overlapping the area where the pen PN is not positioned is not driven by charge, the efficiency of charge driving can be improved.

[0255] refer to Fig.18 and Fig.19B , indicating the position PN-dt of the pen PN in the previous frame. Fig.19BIt is shown that the pen PN is sensed in the area overlapping with the fifth charging channel 230ch5 and the sixth charging channel 230ch6. In this case, the sensor driver 200C can provide the first signal SG1 and the second signal SG2 to the channel located in the area including the fifth charging channel 230ch5 and the sixth charging channel 230ch6. For example, the first signal SG1 and the second signal SG2 can be provided to the central loop around the position PN-dt of the pen PN of the previous frame and the area shifted from left to right by two channels based on the central loop.

[0256] Fig.19A Describes sequentially forming three loop coils including a central loop in a tracking charge drive mode, and Fig.19B It is described that five loop coils including a central loop are sequentially formed in the tracking charge driving mode, but the present disclosure is not particularly limited thereto. For example, the number of loop coils sequentially formed in the tracking charge driving mode may be variously changed.

[0257] Fig. 20A The second mode according to one or more embodiments of the present disclosure is described. Fig. 20B The second mode based on the sensing unit SU according to one or more embodiments of the present disclosure is described.

[0258] Fig. 20A and Fig. 20B The pen sensing drive mode is described. Fig. 20B A sensing unit SU through which a first sensing current Ia, a second sensing current Ib, a third sensing current Ic, and a fourth sensing current Id generated by the pen PN flow is shown.

[0259] The RLC resonant circuit of the pen PN may emit a magnetic field at a resonant frequency while discharging the charged electric charge. Through the magnetic field provided by the pen PN, a first induced current Ia may be generated in the first electrode 210, and a second induced current Ib may be generated in the second electrode 220. In addition, a third induced current Ic may be generated in the first auxiliary electrode 230s of the third electrode 230, and a fourth induced current Id may be generated in the second auxiliary electrode 240s of the fourth electrode 240.

[0260] The first coupling capacitor Ccp1 may be formed between the first auxiliary electrode 230s and the first electrode 210, and the second coupling capacitor Ccp2 may be formed between the second auxiliary electrode 240s and the second electrode 220. The third induced current Ic may be transmitted to the first electrode 210 through the first coupling capacitor Ccp1, and the fourth induced current Id may be transmitted to the second electrode 220 through the second coupling capacitor Ccp2.

[0261] The sensor driver 200C may receive a first reception signal PRX1a based on the first sensing current Ia and the third sensing current Ic from the first electrode 210, and may receive a second reception signal PRX2a based on the second sensing current Ib and the fourth sensing current Id from the second electrode 220. The sensor driver 200C may detect input coordinates of the pen PN based on the first reception signal PRX1a and the second reception signal PRX2a.

[0262] During the pen sensing driving mode, one end of both the third electrode 230 and the fourth electrode 240 may be floated. By coupling the first electrode 210 and the third electrode 230 and by coupling the second electrode 220 and the fourth electrode 240, the compensation of the sensing signal may be improved or maximized. The other ends of the third electrode 230 and the fourth electrode 240 may be grounded or floated. Therefore, by coupling the first electrode 210 and the third electrode 230 and by coupling the second electrode 220 and the fourth electrode 240, the third sensing current Ic and the fourth sensing current Id may be sufficiently transmitted to the first electrode 210 and the second electrode 220.

[0263] Fig.21A is an equivalent circuit diagram showing a relationship between one channel CH-c and a pen PN according to one or more comparative embodiments of the present disclosure. Fig. 21B is an equivalent circuit diagram showing a relationship between one channel CH-c and a pen PN according to one or more comparative embodiments of the present disclosure.

[0264] refer to Fig.21A and Fig. 21B , one channel CH-c may be composed of one electrode 210-c connected to the input terminal IT. The input terminal IT may correspond to one pad electrically connected between the sensor driver 200C and one electrode 210-c.

[0265] Capacitors Cbc1, Cbc2, Cbc3, and Cbc4 are defined in one electrode 210-c. Capacitors Cbc1, Cbc2, Cbc3, and Cbc4 may be referred to as parasitic capacitors or base capacitors.

[0266] refer to Fig.21A , if the pen PN approaches a channel CH-c, a first induced electromotive force Vs(t) may be generated in the electrode 210-c by the magnetic field generated by the pen PN. Therefore, an induced current IN-C may be generated in the channel CH-c. Fig.21A and Fig. 21B The input terminal IT can be electrically connected to the sensor driver 200C (see Figure 4 ) corresponds to a pad between a channel CH-c. For example, the input terminal IT may be the first pad PD1 (see Figure 6 ). If the pen PN approaches one channel CH-c, the input terminal IT may be grounded. Therefore, since both ends of the first capacitor Cbc1 among the capacitors Cbc1, Cbc2, Cbc3, and Cbc4 are grounded, current may not flow to the first capacitor Cbc1.

[0267] The induced current IN-C may be proportional to the sum of the capacitances of the capacitors Cbc2, Cbc3, and Cbc4. For example, assuming that the capacitance of each of the capacitors Cbc2, Cbc3, and Cbc4 is Cb, the induced current IN-C varying with time may be expressed as the following mathematical expression 1.

[0268] Mathematical expression 1

[0269]

[0270] refer to Fig. 21B , if the pen PN approaches a channel CH-c, an induced current IF-C may be generated in the channel CH-c by the magnetic field generated by the pen PN. Because both ends of the first capacitor Cbc1, the second capacitor Cbc2, and the third capacitor Cbc3 among the capacitors Cbc1, Cbc2, Cbc3, and Cbc4 are grounded, the current may not flow to the capacitors Cbc1, Cbc2, and Cbc3. Assuming that the capacitance of the fourth capacitor Cbc4 is Cb, the induced current IF-C that varies with time can be expressed as the following mathematical expression 2.

[0271] Mathematical Expression 2

[0273] refer to Fig.21A and Fig. 21B , if the pen PN is positioned in an area adjacent to the input terminal IT, or if the pen PN is positioned in an area away from the input terminal IT, it can be seen that the intensity of the induced current may be different. For example, a signal input from the pen PN in an area away from the input terminal IT or a signal input from the pen PN in an area away from the sensor driver 200C may be smaller than a signal input from the pen PN in an area close to the input terminal IT or a signal input from the pen PN in an area close to the sensor driver 200C. For example, the induced current IF-C may not be large enough to sense the input of the pen PN.

[0274] Fig.22A is an equivalent circuit diagram showing a relationship between one channel CH and a pen PN according to one or more embodiments of the present disclosure. Fig. 22B is an equivalent circuit diagram showing a relationship between one channel CH and a pen PN according to one or more embodiments of the present disclosure.

[0276] A plurality of first coupling capacitors Ccp11, Ccp12, Ccp13, and Ccp14 may be defined between the first electrode 210 and the first auxiliary electrode 230s. Capacitors Cbc1, Cbc2, Cbc3, and Cbc4 are defined in the first electrode 210. Capacitors Cbc1, Cbc2, Cbc3, and Cbc4 may be referred to as parasitic capacitors or base capacitors.

[0277] The input terminal IT may correspond to one pad (e.g., a first pad PD1 electrically connected between the sensor driver 200C and the first electrode 210). One end of the first auxiliary electrode 230s may be electrically connected to the fifth pad PD5, and the other end of the first auxiliary electrode 230s may be electrically connected to the third trace 230rt1. In one or more embodiments of the present disclosure, the fifth pad PD5 may be floated, and the third trace 230rt1 may be grounded or grounded through a bias capacitor.

[0278] refer to Fig.22A , if the pen PN approaches one channel CH, a first induced electromotive force Vs(t) may be generated in the first electrode 210 by a magnetic field generated by the pen PN, and a second induced electromotive force Va(t) may be generated in the first auxiliary electrode 230s of the third electrode 230. A first induced current IN-M and a third induced current IN-B may be generated by the first induced electromotive force Vs(t), and a second induced current IN-A may be generated by the second induced electromotive force Va(t). Therefore, the total induced current IN input to the input terminal IT may correspond to the sum of the first induced current IN-M, the second induced current IN-A, and the third induced current IN-B.

[0279] For example, it is assumed that the capacitance of each of the capacitors Cbc1 , Cbc2 , Cbc3 , and Cbc4 is Cb, and the capacitance of each of the first coupling capacitors Ccp11 , Ccp12 , Ccp13 , and Ccp14 is Cc.

[0288]

[0289] The first induced current IN-M may be an induced current due to at least some of the capacitors Cbc1, Cbc2, Cbc3, and Cbc4, and may be referred to as an auxiliary induced current. The first induced current IN-M generated in the first electrode 210 may be referred to as a first auxiliary induced current, and the first induced current IN-M generated in the second electrode 220 may be referred to as a second auxiliary induced current. Each of the second induced current IN-A and the third induced current IN-B may be an induced current due to at least some of the first coupling capacitors Ccp11, Ccp12, Ccp13, and Ccp14, and may be referred to as a coupled induced current.

[0290] refer to Fig. 22B , if the pen PN approaches one channel CH, a first induced electromotive force Vs(t) may be generated in the first electrode 210 by a magnetic field generated by the pen PN, and a second induced electromotive force Va(t) may be generated in the first auxiliary electrode 230s of the third electrode 230. Since both ends of each of the capacitors Cbc1, Cbc2, and Cbc3 located between the first induced electromotive force Vs(t) and the input terminal IT are grounded, current may not flow to the capacitors Cbc1, Cbc2, and Cbc3.

[0291] The first induced current IF-M and the third induced current IF-B may be generated by the first induced electromotive force Vs(t), and the second induced current IF-A may be generated by the second induced electromotive force Va(t). Therefore, the total induced current IF input to the input terminal IT may correspond to the sum of the first induced current IF-M, the second induced current IF-A, and the third induced current IF-B.

[0292] For example, it is assumed that the capacitance of each of the capacitors Cbc1 , Cbc2 , Cbc3 , and Cbc4 is Cb, and the capacitance of each of the first coupling capacitors Ccp11 , Ccp12 , Ccp13 , and Ccp14 is Cc.

Therefore, the total induced current IF may be greater than the total induced current IF-C according to one or more comparative embodiments of the present disclosure, and the intensity of the total induced current IF may be large enough to sense the input of the pen PN. In addition, at the first point PP1, the total induced current IN may be greater than the total induced current IN-C according to one or more comparative embodiments of the present disclosure. Therefore, the intensity of each of the total induced current IN at the first point PP1 and the total induced current IF at the second point PP2 may be ensured to be a value (e.g., a predetermined value) or greater.
