[0086] In the present specification, the expression that a first component (or region, layer, portion, part, etc.) is "on" a second component, "connected to" or "coupled to" a second component means that the first component is directly on the second component, directly connected to or directly coupled to the second component, or means that a third component is interposed between the first component and the second component.

[0087] The same reference numerals refer to the same components. In addition, in the drawings, in order to effectively describe the technical content, the thickness, ratio and size of the components are exaggerated. The term "and / or" includes one or more combinations of related elements defined in each thereof.

[0088] Although the terms "first", "second", etc. may be used to describe various components, these components should not be interpreted as being limited by these terms. These terms are only used to distinguish one component from another component. For example, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component without departing from the scope and spirit of the present disclosure. The articles "a", "an", and "the" are in the singular because they have a single referent, but the use of the singular form in the specification should not exclude the presence of more than one referent.

[0089] Furthermore, the terms "under," "below," "on," "above," etc. are used to describe the relationship between components shown in the drawings. Conceptually relative terms are described based on the directions shown in the drawings.

[0090] It will be understood that the terms "includes", "comprising", "having", etc. specify the presence of the features, numbers, steps, operations, elements or components, or a combination thereof, described in the specification, but do not exclude the possibility of the presence or addition of one or more other features, numbers, steps, operations, elements or components, or a combination thereof.

[0091] Unless otherwise defined, all terms (including technical terms and scientific terms) used in the specification have the same meaning as those generally understood by those skilled in the art to which the present disclosure belongs. In addition, 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 field, and should not be interpreted in an idealized or overly formalized meaning unless explicitly defined herein.

[0092] The terms "part" and "unit" mean a software component or a hardware component that performs a specific function. For example, a hardware component may include 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. Thus, 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 procedure, 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.

[0093] Hereinafter, aspects of some embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings.

[0094] Figure 1A is a perspective view of an electronic device 1000 according to some embodiments of the present disclosure. Figure 1B is a rear perspective view of an electronic device 1000 according to some embodiments of the present disclosure.

[0095] refer to Figure 1A and Figure 1B , the electronic device 1000 may be a device configured to be activated based on or according to an electrical signal. For example, the electronic device 1000 may be configured to display an image and may be configured to sense an input (e.g., external input) applied from the outside (e.g., from an external device or object). The external input may be an input from a user. The user's input may include various types of external inputs, such as a part of the user's body (e.g., a user's finger), a pen (or stylus) PN, light, heat, and / or pressure.

[0096] 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 panels separated from each other. For example, as described in more detail below, the first display panel DP1 and the second display panel DP2 may be located on opposite sides of the electronic device 1000. The first display panel DP1 may be referred to as a "main display panel". The second display panel DP2 may be referred to as an "auxiliary display panel" or an "external display panel". According to some embodiments, as described in more detail below, when the electronic device 1000 is in a folded state, the first display panel DP1 may be located on an inner side of the electronic device 1000 so that different non-folding areas of the first display panel DP1 on opposite sides of the folding area of ​​the first display panel DP1 face each other in the folded state. According to some embodiments, when the electronic device 1000 is in a folded state, the second display panel DP2 may be located on the outer side of the electronic device 1000.

[0097] The first display panel DP1 may include first display units DA1-F (eg, Figure 1A ) and a peripheral area NDA around the first display unit DA1-F. The second display panel DP2 may include second display units DA2-F (eg, Figure 1B ). The area of ​​the second display panel DP2 may be smaller than that of the first display panel DP1. The area of ​​the first display unit DA1-F may be larger than that of the second display unit DA2-F so as to correspond to the size of the first display panel DP1 and the size of the second display panel DP2.

[0098] When the electronic device 1000 is unfolded, the first display unit DA1-F may have a plane parallel (or substantially parallel) to a plane defined by 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 relative to the third direction DR3.

[0099] The first display panel DP1 or the first display unit DA1-F may include a folding area FA and a plurality of non-folding areas NFA1 and NFA2, wherein the folding area FA is configured to be folded and unfolded (e.g., without damaging the electronic device 1000), and the plurality of non-folding areas NFA1 and NFA2 are spaced apart from each other with the folding area FA therebetween. The second display panel DP2 may overlap one of the plurality of non-folding areas NFA1 and NFA2. For example, the second display panel DP2 may overlap the first non-folding area NFA1.

[0100] The display direction of the first image IM1a displayed in a portion of the first display panel DP1 (e.g., the first non-folding area NFA1) may be opposite to the display direction of the second image IM2a displayed in the second display panel DP2. For example, the first image IM1a may be displayed in a third direction DR3, and the second image IM2a may be displayed in a fourth direction DR4 which is a direction opposite to the third direction DR3.

[0101] According to some embodiments of the present disclosure, the folding area FA may be curved based on (e.g., around) a folding axis extending in a direction parallel to the long side of the electronic device 1000 (e.g., the second direction DR2). When the electronic device 1000 is folded, the folding area FA has a curvature and a radius of curvature (e.g., a set curvature and a radius of curvature or a predetermined curvature and a radius of curvature). The first non-folding area NFA1 and the second non-folding area NFA2 may face each other, and the electronic device 1000 may be folded inwardly so that the first display unit DA1-F is not exposed to the outside.

[0102] According to some embodiments of the present disclosure, the electronic device 1000 can be folded outward so that the first display unit DA1-F is exposed to the outside. According to some embodiments of the present disclosure, in the unfolded state, the electronic device 1000 can be folded both inwardly and outwardly, but the embodiments of the present disclosure are not limited thereto.

[0103] Figure 1A It is shown that one folding area FA is defined in the electronic device 1000, but the embodiments of the present disclosure are 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. In each unfolded state of the multiple folding areas, the electronic device 1000 may be folded inward or outward.

[0104] According to some embodiments of the present disclosure, at least one of the first display panel DP1 and the second display panel DP2 may be configured to sense the input of the pen PN even when it does not include a digitizer. Therefore, since the digitizer for sensing the pen PN may be omitted, an increase in the thickness of the electronic device 1000, an increase in the weight of the electronic device 1000, or a decrease in the flexibility of the electronic device 1000 due to the addition of the digitizer may not occur. Therefore, not only the first display panel DP1 but also the second display panel DP2 may be designed to sense the pen PN.

[0105] Figure 2 is a perspective view of an electronic device 1000 - 1 according to some embodiments of the present disclosure.

[0106] Figure 2 It is shown that the electronic device 1000 - 1 is a mobile phone, and the electronic device 1000 - 1 may include a display panel DP.

[0107] According to some embodiments of the present disclosure, the display panel DP may be configured to sense an input applied from the outside (eg, an external input). The external input may be an input of a user. The input of the user may include, for example, a part of the user's body (eg, a finger of the user), a pen PN (see Figure 1A ), various types of external inputs such as light, heat or pressure.

[0108] According to some embodiments of the present disclosure, even if the display panel DP does not include a digitizer, the display panel DP may be configured to sense the input of the pen PN. Therefore, since the digitizer for sensing the pen PN may be omitted, the thickness and weight of the electronic device 1000-1 may not be increased due to the addition of the digitizer.

[0109] Figure 1A A foldable type of electronic device 1000 is shown, and Figure 2A bar-shaped (or non-foldable or flat or plate-shaped) type electronic device 1000-1 is shown. However, the embodiments of the present disclosure described in more detail below are not limited thereto. For example, the description described below can be applied to various electronic devices, such as a rollable type electronic device, a slidable type electronic device, and a stretchable type electronic device.

[0110] Figure 3 is a schematic cross-sectional view of a display panel DP according to some embodiments of the present disclosure.

[0111] refer to Figure 3 , the display panel DP may include a display layer 100 and a sensor layer 200 .

[0112] The display layer 100 may be a component that basically generates an image or displays an image. The display layer 100 may be a light-emitting display layer. For example, the display layer 100 may be an organic light-emitting display layer, an inorganic light-emitting display layer, an organic-inorganic light-emitting display layer, a quantum dot display layer, a micro-LED display layer, or a nano-LED display layer. The display layer 100 may include a base layer 110, a circuit layer 120, a light-emitting element layer 130, and an encapsulation layer 140.

[0113] The base layer 110 may be a member providing a base surface on which the circuit layer 120 is located. The base layer 110 may include 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 according to embodiments of the present disclosure.

[0114] The circuit layer 120 may be located on the base layer 110. The circuit layer 120 may include an insulating layer, a semiconductor pattern, a conductive pattern, and a signal line. The insulating layer, the semiconductor layer, and the conductive layer may be formed on the base layer 110 in a manner such as coating, evaporation, etc. Then, the insulating layer, the semiconductor layer, and the conductive layer may be selectively patterned by performing a photolithography process multiple times.

[0115] 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.

[0116] 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 foreign substances or contaminants such as moisture, oxygen, and dust particles.

[0117] The sensor layer 200 may be located on the display layer 100. The sensor layer 200 may sense an external input applied from the outside. The sensor layer 200 may be an integrated sensor continuously formed during the manufacturing process of the display layer 100, or may be an external sensor attached to the display layer 100. In the present disclosure, the sensor layer 200 may be referred to as a sensor, an input sensing layer, an input sensing panel, or an electronic device for sensing input coordinates.

[0118] According to some embodiments of the present disclosure, the sensor layer 200 can sense both input from a passive input source such as a user's body and input from an input device (e.g., an active input source) for generating a magnetic field of a resonant frequency (e.g., a set or predetermined resonant frequency). The input device may be referred to as a "pen," "input pen," "magnetic pen," "stylus," or "electromagnetic resonance pen."

[0119] Figure 4 is a block diagram for describing the operation of the electronic device 1000 according to some embodiments of the present disclosure.

[0120] refer to Figure 4 , the electronic device 1000 may include a display layer 100, a sensor layer 200, a display driver 100C (e.g., a first driver circuit), a sensor driver 200C (e.g., a second driver circuit), a main driver 1000C (e.g., a third circuit) and a power supply circuit 1000P.

[0121] The sensor layer 200 can sense a first input 2000 or a second input 3000 applied from the outside (e.g., an external input from an external source). Each of the first input 2000 and the second input 3000 can be an input method or input source capable of providing a capacitance change of the sensor layer 200, or can be an input method capable of causing an induced current in the sensor layer 200. For example, the first input 2000 can be a passive input method such as a user's body (e.g., a user's finger). The second input 3000 can be an input of a pen PN or an input of an RFIC tag. For example, the pen PN can be a passive pen or an active pen.

[0122] According to some embodiments of the present disclosure, the pen PN may be a device that generates a magnetic field of a resonant frequency (e.g., a set or predetermined resonant frequency). The pen PN may be configured to send an output signal based on an electromagnetic resonance method. The pen PN may be referred to as an "input device", "input pen", "magnetic pen", "stylus pen" or "electromagnetic resonance pen".

[0123] The pen PN may include an RLC resonant circuit, and the RLC resonant circuit may include an inductor L and a capacitor C. According to some 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 according to embodiments of the present disclosure, it is not particularly limited thereto.

[0124] The inductor L generates a current through a magnetic field formed in the sensor layer 200. However, the embodiments according to the present disclosure are not particularly limited to this. For example, when the pen PN works as an active input device, the pen PN can generate a current even when 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. Then, the inductor L can emit a magnetic field at a resonant frequency. The induced current can flow in the sensor layer 200 through the magnetic field emitted by the pen PN, and the induced current can be transmitted to the sensor driver 200C as a receiving signal (or sensing signal).

[0125] 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."

[0126] 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, and a data enable signal.

[0127] 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 for determining an operation mode of the sensor driver 200C and the sensor layer 200.

[0128] 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 in an area (e.g., a set or predetermined area) of the display panel DP, or mounted on a separate printed circuit board in a chip on film (COF) method to be electrically connected to the sensor layer 200.

[0129] The sensor driver 200C and the sensor layer 200 can selectively operate in a first mode or a second mode. For example, the first mode can be a mode for sensing a touch input (e.g., a first input 2000). The second mode can be a mode for sensing an input of a pen PN (e.g., a second input 3000). The first mode can be referred to as a "touch sensing mode", and the second mode can be referred to as a "pen sensing mode".

[0130] The conversion between the first mode and the second mode can be implemented in various ways. For example, the sensor driver 200C and the sensor layer 200 can be driven in a time-division method in the first mode and the second mode, 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 (for example, via the user's interface) or the user's specific action, and the first mode or the second mode can be activated or deactivated by activating or deactivating a specific application, or one mode can be converted to another mode. Alternatively, when operating alternately in the first mode and the second mode, the sensor driver 200C and the sensor layer 200 can remain in the first mode when sensing the first input 2000, or can remain in the second mode when sensing the second input 3000.

[0131] 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's 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.

[0132] 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 is not particularly limited thereto according to embodiments of the present disclosure.

The buffer layer BFL may improve the bonding force between the base layer 110 and the semiconductor pattern. The buffer layer BFL may be formed of a plurality of layers. Alternatively, the display layer 100 may further include a barrier layer. The buffer layer BFL may include at least one of silicon oxide, silicon nitride, and silicon oxynitride. For example, the buffer layer BFL may include a structure in which silicon oxide layers and silicon nitride layers are alternately stacked.

For example, the semiconductor pattern may include amorphous silicon, low temperature polycrystalline silicon, or an oxide semiconductor.

The semiconductor pattern may be arranged across pixels according to a specific rule. The semiconductor pattern may have different electrical characteristics depending on whether the semiconductor pattern is doped. The semiconductor pattern may include a first region including a source region SC, a drain region DR and a connection signal line SCL having high conductivity, and a second region including an active region AL having low conductivity. The first region may be doped with an N-type dopant or a P-type dopant. The P-type transistor may include a region doped with a P-type dopant, and the N-type transistor may include a region doped with an N-type dopant. The second region may be an undoped region or a region doped with a concentration lower than that in the first region.

[0137] The conductivity of each of the first regions is greater than that of the second region. The first region can be basically used as an electrode or a signal line. The second region can actually correspond to the active area AL (or channel) of the transistor 100PC. In other words, a portion of the semiconductor pattern can be the active area AL of the transistor 100PC; another portion of the semiconductor pattern can be the source region SC or the drain region DR of the transistor 100PC; and another portion of the semiconductor pattern can be a connection electrode or a connection signal line SCL.

[0139] The source region SC, the active region AL, and the drain region DR of the transistor 100PC may be formed of a semiconductor pattern. The source region SC and the drain region DR may extend from the active region AL in opposite directions to each other in a cross-sectional view. Figure 5 A portion of the connection signal line SCL formed of a semiconductor pattern is shown in . According to some embodiments, the connection signal line SCL may be connected to the drain region DR of the transistor 100PC in a plan view.

[0164] Figure 6 is a plan view of a sensor layer 200 according to some embodiments of the present disclosure. Figure 7 is an enlarged plan view of a sensing unit SU according to some embodiments of the present disclosure. Fig. 8A is a plan view illustrating a first conductive layer 202SU of a sensing unit SU according to some embodiments of the present disclosure. Figure 8B is a plan view illustrating a second conductive layer 204SU of a sensing unit SU according to some embodiments of the present disclosure. Fig. 9 According to some embodiments of the present disclosure, Fig. 8A and Figure 8B FIG. 2 is a cross-sectional view of the sensor layer 200 taken along line II′ shown in FIG.

[0165] refer to Figure 6In the sensor layer 200 , a sensing region 200A and a peripheral region (or peripheral area) 200NA adjacent to the sensing region 200A (eg, outside the periphery or coverage area of ​​the sensing region 200A) may be defined.

[0166] 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 located in the sensing region 200A. The first electrodes 210 may be referred to as first sensing electrodes, the second electrodes 220 may be referred to as second sensing electrodes, the third electrodes 230 may be referred to as first electrodes, and the fourth electrodes 240 may be referred to as second electrodes.

[0167] The first electrode 210, the second electrode 220, the third electrode 230, and the fourth electrode 240 may be connected to each other on opposite sides (eg, Figure 6 The main area of ​​the sensor layer 200 corresponds to the main area between the first peripheral area (e.g., the left side and the right side of the peripheral area 200NA) and the second peripheral area (e.g., the right side of the peripheral area 200NA). Therefore, the main area of ​​the sensor layer 200 may be located between the first peripheral area (e.g., the left side of the peripheral area 200NA) and the second peripheral area (e.g., the right side of the peripheral area 200NA). The main area of ​​the sensor layer 200 may be the sensing area 200A.

[0168] The first electrode 210 may intersect with the second electrode 220. Each of the first electrodes 210 may extend in the second direction DR2. The first electrodes 210 may be arranged to be spaced apart from each other in the first direction DR1. Each of the second electrodes 220 may extend in the first direction DR1. 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 intersects with one of the second electrodes 220.

[0169] Figure 6 Six first electrodes 210 and ten second electrodes 220 are shown, and sixty sensing units SU are shown However, the number of the first electrodes 210 and the number of the second electrodes 220 are not limited thereto.

[0170] refer to Figure 6 and Figure 7 , each of the first electrodes 210 may include first separation electrodes 210dv1 and 210dv2. The first separation electrodes 210dv1 and 210dv2 may extend in the second direction DR2 and may be spaced apart from each other in the first direction DR1. The first separation electrodes 210dv1 and 210dv2 may have a linearly symmetrical shape with respect to a line extending in the second direction DR2.

[0171] Each of the second electrodes 220 may include second separation electrodes 220dv1 and 220dv2. The second electrodes 220 extend in the first direction DR1 and may be spaced apart from each other in the second direction DR2. The second separation electrodes 220dv1 and 220dv2 may have linearly symmetrical shapes with respect to a line extending in the first direction DR1.

[0172] refer to Figure 7 , Fig. 8A , Figure 8B and Fig. 9 , each of the second separation electrodes 220dv1 and 220dv2 may include a sensing pattern 221 and a bridge pattern 222. The sensing pattern 221 and the bridge pattern 222 may be located or formed on different layers, and the sensing pattern 221 and the bridge pattern 222 may be electrically connected to each other through a first contact CNa. For example, the bridge pattern 222 may be included in the first conductive layer 202SU. The sensing pattern 221 and the first separation electrodes 210dv1 and 210dv2 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 In the second conductive layer 204.

[0173] Each of the third electrodes 230 may extend in the second direction DR2. The third electrodes 230 may be arranged to be spaced apart from each other in the first direction DR1. According to some embodiments of the present disclosure, each of the third electrodes 230 may include a plurality of first auxiliary electrodes 230s electrically connected in parallel. 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 may decrease. Therefore, power efficiency may be relatively improved, and sensing sensitivity may be relatively improved. On the other hand, as the number of the first auxiliary electrodes 230s included in each of the third electrodes 230 decreases, the loop coil pattern formed by using the third electrode 230 may be implemented in different forms.

[0174] Figure 6 It is shown that one third electrode 230 includes two first auxiliary electrodes 230s, but the embodiment according to the present disclosure is not particularly limited thereto. The first auxiliary electrodes 230s may be arranged to correspond one to one with the first electrodes 210. Therefore, one sensing unit SU may include part of one first auxiliary electrode 230s.

[0175] A coupling capacitor may be defined between one first electrode 210 and one first auxiliary electrode 230s. In this case, a current induced when a pen is sensed may be transmitted from the first auxiliary electrode 230s to the first electrode 210 through the coupling capacitor. In other words, the first auxiliary electrode 230s may compensate for a signal transmitted from the first electrode 210 to the sensor driver 200C. Therefore, a maximum effect may be achieved when a phase of a signal induced in the first auxiliary electrode 230s matches a phase of a signal induced in the first electrode 210. Therefore, a center of each of the first electrodes 210 in the first direction DR1 may overlap a center of each of the first auxiliary electrodes 230s in the first direction DR1.

[0176] According to some 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 first electrodes 210 included in the sensor layer 200 may be greater than the number of third electrodes 230. For example, the number of first electrodes 210 may be equal to the product of the number of third electrodes 230 included in the sensor layer 200 and the number of first auxiliary electrodes 230s included in each of the third electrodes 230. Figure 6 In the embodiment, the number of the first electrodes 210 may be 6, the number of the third electrodes 230 may be 3; and the number of the first auxiliary electrodes 230s included in each of the third electrodes 230 may be 2, although the embodiments according to the present disclosure are not limited thereto, and the number of the first electrodes 210, the third electrodes 230, and the first auxiliary electrodes 230s may vary according to various embodiments.

[0177] The fourth electrodes 240 may be arranged in the second direction DR2, and the fourth electrodes 240 may extend in the first direction DR1. According to some embodiments of the present disclosure, each of the fourth electrodes 240 may include a second auxiliary electrode 240s1 or 240s2 electrically connected to each other. The second auxiliary electrodes 240s1 and 240s2 may be referred to as a 2-1st auxiliary electrode 240s1 and a 2-2nd auxiliary electrode 240s2, respectively.

[0178] The wiring directions of the 2-1st auxiliary electrode 240s1 and the 2-2nd auxiliary electrode 240s2 may be different from each other. Figure 6 Two fourth electrodes 240 and five second auxiliary electrodes 240 s 1 or 240 s 2 included in each of the fourth electrodes 240 are shown.

[0179] In this specification, the fact that the wiring directions are different from each other means that the connection positions of the electrodes and the traces (also referred to as lines) are different from each other. For example, the first connection position of the fourth trace 240t-1 electrically connected to the 2-1 auxiliary electrode 240s1 may be different from the second connection position of the fourth trace 240t-2 electrically connected to the 2-2 auxiliary electrode 240s2. The first connection position may be placed at the left end based on the 2-1 auxiliary electrode 240s1. The second connection position may be placed at the right end of the 2-2 auxiliary electrode 240s2.

[0180] Figure 6 It is shown that five 2-1 auxiliary electrodes 240s1 are electrically connected to each other, and five 2-2 auxiliary electrodes 240s2 are electrically connected to each other. That is, the area ratio of the two fourth electrodes 240 or the number ratio of the second auxiliary electrodes 240s1 or 240s2 included in each of the two fourth electrodes 240 may have a ratio of 1:1. However, embodiments according to the present disclosure are not particularly limited thereto. For example, according to some embodiments, the number of the 2-1 auxiliary electrodes 240s1 may be different from the number of the 2-2 auxiliary electrodes 240s2.

[0181] According to some embodiments of the present disclosure, when each of the fourth electrodes 240 includes the second auxiliary electrode 240s1 or 240s2 connected in parallel, the area of ​​one fourth electrode 240 may be increased. In addition, as the resistance of each of the fourth electrodes 240 decreases, the second input 3000 (see Figure 4 )’s sensing sensitivity can be relatively improved.

[0182] A coupling capacitor may be defined between one second electrode 220 and one 2-1st auxiliary electrode 240s1. In this case, a current induced when sensing the pen PN may be transmitted from the 2-1st auxiliary electrode 240s1 to the second electrode 220 through the coupling capacitor. In other words, the 2-1st auxiliary electrode 240s1 may compensate for a signal transmitted from the second electrode 220 to the sensor driver 200C. Therefore, a maximum effect may be achieved when a phase of a signal induced in the 2-1st auxiliary electrode 240s1 matches a phase of a signal induced in the second electrode 220. Therefore, a center of each of the second electrodes 220 in the second direction DR2 may overlap a center of each of the 2-1st auxiliary electrodes 240s1 in the second direction DR2.

[0183] refer to Figure 6 , Fig. 8A and Figure 8B, each of the first auxiliary electrodes 230s included in the third electrode 230 may include a 3-1st pattern 231 and a 3-2nd pattern 232. The 3-1st pattern 231 and the 3-2nd pattern 232 may be placed on different layers. The 3-1st pattern 231 and the 3-2nd pattern 232 may be electrically connected to each other through the second contact CNb. The 3-1st pattern 231 may be included in the first conductive layer 202SU. The 3-2nd pattern 232 may be included in the second conductive layer 204SU.

[0184] According to some embodiments of the present disclosure, a portion of the 3-1st pattern 231 may overlap a portion of each of the first separation electrodes 210dv1 and 210dv2 . Therefore, a coupling capacitor may be disposed (or formed) between the first electrode 210 and the third electrode 230 .

[0185] refer to Figure 6 , Fig. 8A and Figure 8B , the second auxiliary electrode 240s1 or 240s2 included in the fourth electrode 240 may include a 4-1st pattern 241, a 4-2nd pattern 242, and a 4-3rd pattern 243. The 4-2nd pattern 242 and the 4-3rd pattern 243 may be placed on the same layer as each other. The 4-1st pattern 241 may be placed on a different layer from the 4-2nd pattern 242 and the 4-3rd pattern 243. The 4-1st pattern 241 and the 4-2nd pattern 242 may be electrically connected to each other through the third contact CNc. The 4-1st pattern 241 and the 4-3rd pattern 243 may be electrically connected to each other through the fourth contact CNd. The 4-2nd pattern 242 and the 4-3rd pattern 243 may be included in the first conductive layer 202SU, and the 4-1st pattern 241 may be included in the second conductive layer 204SU.

[0186] According to some embodiments of the present disclosure, a portion of the 4-2nd pattern 242 may overlap the sensing pattern 221 of each of the second separation electrodes 220dv1 and 220dv2. Thus, a coupling capacitor may be defined (or disposed / formed) between the second electrode 220 and the fourth electrode 240.

[0187] According to some 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. According to some embodiments of the present disclosure, the dummy pattern DMP may be omitted. Alternatively, the dummy pattern DMP may be electrically connected to the first electrode 210 or the second electrode 220.

[0188] The sensor layer 200 may further include a plurality of first traces 210t disposed in the peripheral area 200NA, a plurality of first pads PD1 connected to the first traces 210t in a one-to-one correspondence, 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.

[0189] The first trace 210t may be electrically connected to the first electrode 210 in a one-to-one correspondence. Two first separation electrodes 210dv1 and 210dv2 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 branch units to be connected to the two first separation electrodes 210dv1 and 210dv2. According to some embodiments of the present disclosure, the two first separation electrodes 210dv1 and 210dv2 may be connected to each other within the sensing area 200A.

[0190] The second trace 220t may be electrically connected to the second electrode 220 in a one-to-one correspondence. Two second separation electrodes 220dv1 and 220dv2 included in one second electrode 220 may be connected to one of the second traces 220t. Each of the second traces 220t may include a plurality of branch units to be connected to the two second separation electrodes 220dv1 and 220dv2. According to some embodiments of the present disclosure, the two second separation electrodes 220dv1 and 220dv2 may be connected to each other within the sensing area 200A.

[0191] According to some embodiments of the present disclosure, the second electrode 220 may be classified (or divided) into a first electrode group 220G1 and a second electrode group 220G2. The first electrode group 220G1 and the second electrode group 220G2 may be adjacent in the second direction DR2. Some of the second electrodes 220-1 (hereinafter referred to as "2-1st electrodes") among the second electrodes 220 may be included in the first electrode group 220G1, and some of the second electrodes 220-2 (hereinafter referred to as "2-2nd electrodes") among the remaining second electrodes 220 among the second electrodes 220 may be included in the second electrode group 220G2.

[0192] The boundary RIL may be defined between the first electrode group 220G1 and the second electrode group 220G2. Thus, the 2-1st electrode 220-1 and the 2-2nd electrode 220-2 may be spaced apart from each other with the boundary RIL therebetween. The wiring direction of each of the 2-1st electrodes 220-1 may be different from the wiring direction of each of the 2-2nd electrodes 220-2.

[0193] The second traces 220t may be classified into a first trace group 220tG1 electrically connected to the first electrode group 220G1 and a second trace group 220tG2 electrically connected to the second electrode group 220G2. The first trace group 220tG1 and the second trace group 220tG2 may be spaced apart from each other with the sensing area 200A therebetween.

[0194] The sensor layer 200 may further include a third trace 230rt1 disposed in the peripheral area 200NA, a plurality of third pads PD3 connected to one end and the other end of the third trace 230rt1, fourth traces 240t-1 and 240t-2, a fourth pad PD4 connected to the fourth traces 240t-1 and 240t-2 in a one-to-one correspondence, a fifth trace 230rt2, and a fifth pad PD5 connected to the fifth trace 230rt2 in a one-to-one correspondence.

[0195] The third trace 230rt1 may be electrically connected to the entire third electrode 230. The third trace 230rt1 may include a first line portion 231t extending in the first direction DR1 and electrically connected to the third electrode 230, a second line portion 232t extending from a first end of the first line portion 231t in the second direction DR2, and a third line portion 233t extending from a second end of the first line portion 231t in the second direction DR2.

[0196] According to some 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 the same as the resistance of one of the third electrodes 230. Therefore, the second line portion 232t and the third line portion 233t may be used as the third electrode 230, and the same effect as the third electrode 230 also being placed in the peripheral area 200NA may be obtained. For example, one of the second line portion 232t and the third line portion 233t and one of the third electrodes 230 may form a coil. Therefore, the pen PN located in the area adjacent to the peripheral area 200NA may also be fully charged by a loop including the second line portion 232t or the third line portion 233t.

[0197] According to some embodiments of the present disclosure, in order to adjust the resistance of each of the second line portion 232t and the third line portion 233t, the width of each of the second line portion 232t and the third line portion 233t in the first direction DR1 may be adjusted. However, this is merely an example, and the first line portion 231t, the second line portion 232t, and the third line portion 233t may have the same (or substantially the same) width as each other.

[0198] The fifth traces 230rt2 may be connected to the third electrodes 230 in a one-to-one correspondence. In other words, the number of the fifth traces 230rt2 may correspond to the number of the third electrodes 230. Figure 6 , three fifth traces 230rt2 are shown.

[0199] According to some embodiments of the present disclosure, the fifth trace 230rt2 and the fifth pad PD5 may be omitted, and the charging driving mode for charging the pen PN may be omitted. In this case, the sensor layer 200 may sense input from an active pen capable of emitting a magnetic field even when no magnetic field is provided from the sensor layer 200.

[0200] According to some embodiments of the present disclosure, the fourth electrode 240 may include one fourth electrode 240G1 (hereinafter referred to as "4-1st electrode") overlapping the first electrode group 220G1 and another fourth electrode 240G2 (hereinafter referred to as "4-2nd electrode") overlapping the second electrode group 220G2. The 4-1st electrode 240G1 may include a 2-1st auxiliary electrode 240s1. The 4-2nd electrode 240G2 may include a 2-2nd auxiliary electrode 240s2.

[0201] The fourth traces 240t-1 and 240t-2 may be spaced apart from each other with the sensing region 200A therebetween. The fourth trace 240t-1 (hereinafter referred to as the "4-1st trace") among the fourth traces 240t-1 and 240t-2 may be electrically connected to the 4-1st electrode 240G1. The other fourth trace 240t-2 (hereinafter referred to as the "4-2nd trace") among the fourth traces 240t-1 and 240t-2 may be electrically connected to the 4-2nd electrode 240G2. One end of each of the 2-1st auxiliary electrodes 240s1 may be connected to the 4-1st trace 240t-1. One end of each of the 2-2nd auxiliary electrodes 240s2 may be connected to the 4-2nd trace 240t-2.

[0202] The 4-1st trace 240t-1 and the 4-2nd trace 240t-2 may be spaced apart from each other, with the sensing region 200A being between them. The 4-1st trace 240t-1 and the first trace group 220tG1 may be spaced apart from each other, with the sensing region 200A being between them. In addition, the 4-2nd trace 240t-2 and the second trace group 220tG2 may be spaced apart from each other, with the sensing region 200A being between them. The second trace group 220tG2 and the 4-1st trace 240t-1 may be placed in a portion of the peripheral area 200NA placed on the left side of the sensing region 200A. The first trace group 220tG1 and the 4-2nd trace 240t-2 may be placed in a portion of the peripheral area 200NA placed on the right side of the sensing region 200A.

[0204] 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 shape extending in a direction (e.g., a set or predetermined direction) and may be connected to each other. The shape may have various shapes such as a straight line, a line with a protrusion, or an uneven line. An opening in which no grid structure is located 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.

[0205] Fig. 10A and Fig. 10B The grid structure includes grid lines extending in a first crossing direction CDR1 intersecting the first direction DR1 and the second direction DR2 and grid lines extending in a second crossing direction CDR2 intersecting the first crossing direction CDR1. 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. In other words, the grid structure may be changed into various forms.

[0206] Fig.11 FIG. 2 is a diagram showing a sensor driver 200C according to some embodiments of the present disclosure (see FIG. Figure 4 ) operation.

[0207] refer to Figure 4 and Fig.11 , the sensor driver 200C may be configured to selectively operate in one of the first operation mode DMD1 , the second operation mode DMD2 , and the third operation mode DMD3 .

[0208] The first operation mode DMD1 may be referred to as a "touch and pen standby mode"; the second operation mode DMD2 may be referred to as a "touch activated and pen standby mode"; and the third operation mode DMD3 may be referred to as a "pen activated mode". The first operation mode DMD1 may be in a mode for waiting for the first input 2000 and the second input 3000. The second operation mode DMD2 may be in a mode for sensing the first input 2000 and waiting for the second input 3000. The third operation mode DMD3 may be a mode for sensing the second input 3000.

[0209] According to some embodiments of the present disclosure, the sensor driver 200C may be first driven in the first operating mode DMD1. When the first input 2000 is sensed in the first operating mode DMD1, the sensor driver 200C may be converted (or changed) to the second operating mode DMD2. Alternatively, when the second input 3000 is sensed in the first operating mode DMD1, the sensor driver 200C may be converted (or changed) to the third operating mode DMD3.

[0210] According to some embodiments of the present disclosure, when the second input 3000 is sensed in the second operation mode DMD2, the operation mode of the sensor driver 200C may be converted to the third operation mode DMD3. When the first input 2000 is terminated (or not detected) in the second operation mode DMD2, the operation mode of the sensor driver 200C may be converted to the first operation mode DMD1. When the second input 3000 is terminated (or not detected) in the third operation mode DMD3, the operation mode of the sensor driver 200C may be converted to the first operation mode DMD1.

[0211] Fig. 12A FIG. 2 is a diagram showing a sensor driver 200C according to some embodiments of the present disclosure (see FIG. Figure 4 ) operation.

[0212] refer to Figure 4 , Fig.11 and Fig. 12A , operations in the first operation mode DMD1 , the second operation mode DMD2 , and the third operation mode DMD3 are shown in order of time t.

[0213] 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 perform a scan driving operation to detect the second input 3000. During the first mode MD1-d, the sensor layer 200 may perform a scan driving operation to detect the first input 2000. Fig. 12AIt 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.

[0214] 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 perform a scan driving operation to detect the second input 3000. During the first mode MD1, the sensor layer 200 may perform a scan driving operation to detect the coordinates of the first input 2000.

[0215] 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 perform a scan driving operation to detect the coordinates 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 terminated (or the second input 3000 is not detected).

[0216] Reference together Figure 6 In the first mode MD1-d and the first mode MD1, all of the third electrodes 230 and the fourth electrodes 240 may be grounded. Therefore, the touch noise entering through the third electrodes 230 and the fourth electrodes 240 may be prevented or reduced.

[0217] In the second mode MD2-d and the second mode MD2, one 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, the compensation of the sensing signal may be maximized or improved by the coupling between the first electrode 210 and the third electrode 230 and the coupling between the second electrode 220 and the fourth electrode 240.

[0218] Fig. 12B is a diagram illustrating the operation of the second mode MD2 according to some embodiments of the present disclosure.

[0219] refer to Fig. 12B , the second mode MD2 may include a first driving mode MD2-1 and a second driving mode MD2-2. The first driving mode MD2-1 of the second mode MD2 may be referred to as a "proactive driving mode", and the second driving mode MD2-2 of the second mode MD2 may be referred to as a "main driving mode".

[0220] The first driving mode MD2-1 may include a touch driving mode FT, a charging driving mode SCC, and a pre-pen sensing driving mode PSS. The second driving mode MD2-2 may include a touch driving mode FT, a charging driving mode SCC, and a pen sensing driving mode SS.

[0221] The touch drive mode FT may be a mode driven to detect a touch of a palm or a blade of a hand. However, only the touch is detected, and an operation corresponding to the input may not be performed. In other words, the touch drive mode FT may only detect that a touch of a palm or a blade of a hand is occurring, and may be a mode that identifies coordinates without performing an operation corresponding to the identified result. In other words, according to some embodiments, during the touch drive mode FT, it may be detected or determined whether a touch occurs, regardless of the position or coordinates of the touch. According to some embodiments of the present disclosure, the touch drive mode FT may be omitted in at least one of the first drive mode MD2-1 and the second drive mode MD2-2.

[0222] The charging driving mode SCC may be a mode for providing a signal for charging the pen PN. In the charging driving mode SCC, a magnetic field may be formed in the sensor layer 200. In this case, the pen PN adjacent to the sensor layer 200 may be charged. The charging driving mode SCC may be referred to as a driving mode for generating a magnetic field for charging the pen PN.

[0223] The pre-pen sensing driving mode PSS may be a mode for detecting an effective area in which the pen PN is located. For example, the sensor driver 200C may change the weight applied to each of the signals received from the second electrode 220 according to the position of the effective area. That is, the pre-pen sensing driving mode PSS may be a mode for determining a weight value. The weight value may be at least one of a weight and a gain.

[0224] The pen sensing driving mode SS may be a mode for detecting the position of the pen PN. For example, the sensor driver 200C may change one of the weight and the gain, and may detect the pen coordinates based on the signals received from the first electrode 210 and the second electrode 220.

[0225] Fig.13 is a diagram for describing a first mode according to some embodiments of the present disclosure.

[0226] refer to Fig. 12A and Fig.13 , the first mode MD1 - d of the first operation mode DMD1 and the first mode MD1 of the second operation mode DMD2 may include a mutual capacitance detection mode. Fig.13 is a diagram for describing the mutual capacitance detection mode in the first mode MD1 - d and the first mode MD1 .

[0227] In the mutual capacitance detection mode, the sensor driver 200C may sequentially provide a transmission signal TX to the first electrode 210, and may detect the coordinates of the first input 2000 by using a reception signal RX detected via the second electrode 220. For example, the sensor driver 200C may be configured to calculate the input coordinates by sensing a change in mutual capacitance between the first electrode 210 and the second electrode 220.

[0228] Fig.13 It is shown that the transmission signal TX is provided to a first electrode 210, and the reception signal RX is output from the second electrode 220. In order to make the representation of the signal clear, Fig.13 It is shown that only one first electrode 210 to which the transmission signal TX is provided is shaded. The sensor driver 200C may detect the input coordinates of the first input 2000 by sensing a change in capacitance between each of the second electrodes 220 and the first electrode 210 .

[0229] In the mutual capacitance detection mode, both the third electrode 230 and the fourth electrode 240 may be grounded. Therefore, noise may not be introduced through the third electrode 230 and the fourth electrode 240.

[0230] According to some embodiments of the present disclosure, at least one of the first mode MD1-d and the first mode MD1 may further include a self-capacitance detection mode. In the self-capacitance detection mode, the sensor driver 200C may be configured to output a driving signal to the first electrode 210 and the second electrode 220, and calculate the input coordinates by sensing the capacitance change between the first electrode 210 and the second electrode 220.

[0231] Fig.14 is a diagram for describing the second mode MD2 (particularly, the charging driving mode SCC) according to some embodiments of the present disclosure. Fig.15A is a graph showing a waveform of a first signal according to some embodiments of the present disclosure. Fig. 15B is a graph showing a waveform of a second signal according to some embodiments of the present disclosure.

[0232] refer to Fig. 12B , Fig.14 , Fig.15A and Fig. 15B The charging driving mode SCC may include a searching charging driving mode and a tracking charging driving mode.

[0233] The search charge drive mode may be a drive mode before the position of the pen PN is sensed. Therefore, the first signal SG1 or the second signal SG2 may be provided to all channels included in the sensor layer 200. In other words, the entire area of ​​the sensor layer 200 may be scanned in the search charge drive mode. When the pen PN is sensed in the search charge drive mode, the sensor layer 200 may be driven to track the charge. For example, in the tracking charge drive mode, the sensor driver 200C may sequentially output the first signal SG1 and the second signal SG2 to the area overlapping the point where the pen PN is sensed instead of the entire sensor layer 200.

[0234] In the charging driving mode SCC, the sensor driver 200C may apply a first signal SG1 to one of the third pad PD3a and the fifth pad PD5a, and may apply a second signal SG2 to the other of the third pad PD3a and the fifth pad PD5a. The second signal SG2 may be an inverse signal of the first signal SG1. For example, the first signal SG1 may be a sinusoidal signal.

[0235] Because the first signal SG1 and the second signal SG2 are applied to at least two pads, the current RFS may have a current path from one pad to another pad. In addition, because the first signal SG1 and the second signal SG2 are sinusoidal signals having an anti-phase relationship with each other, the direction of the current RFS may change periodically. According to some embodiments of the present disclosure, the first signal SG1 and the second signal SG2 may be square wave signals having an anti-phase relationship with each other.

[0236] When the first signal SG1 and the second signal SG2 have an anti-phase relationship, the display layer 100 (see Figure 3 ) The noise caused by the first signal SG1 in the display layer 100 can be offset by the noise caused by the second signal SG2. Therefore, flickering may not occur in the display layer 100, and the display quality of the display layer 100 can be relatively improved.

[0237] According to some embodiments of the present disclosure, the first signal SG1 may be a sinusoidal signal. However, the embodiments of the present disclosure are not limited thereto, and the first signal SG1 may be a square wave signal. In addition, the second signal SG2 may have a constant voltage (e.g., a set or predetermined constant voltage). For example, the second signal SG2 may be a ground voltage. In other words, the pad to which the second signal SG2 is applied is identified to be grounded. In this case, the current RFS may flow from one pad to another. In addition, since the first signal SG1 is a sinusoidal wave signal or a square wave signal even when the other pad is grounded, the direction of the current RFS may change periodically.

[0238] refer to Fig.14, the second signal SG2 is provided through a third pad PD3a connected to a third trace 230rt1, and the first signal SG1 is provided through a fifth pad PD5a connected to the third electrode 230. The current RFS can flow through a current path defined by the fifth pad PD5a, the fifth trace 230rt2 connected to the fifth pad PD5a, the third electrode 230, the portion of the third trace 230rt1 connected to the third pad PD3a, and the third pad PD3a. The current path can have the form of a coil. Therefore, in the charging drive mode SCC of the second mode MD2, the resonant circuit of the pen PN can be charged by the current path.

[0239] According to some embodiments of the present disclosure, the current path of the loop coil pattern may be implemented by components included in the sensor layer 200. Figure 1A ) The pen PN may be charged by using the sensor layer 200. Therefore, since there is no need to add a separate configuration having a loop for charging the pen PN, the thickness and weight of the electronic device 1000 may not be increased and the flexibility of the electronic device 1000 may not be reduced.

[0240] In the charging driving mode SCC, the first electrode 210, the second electrode 220, and the fourth electrode 240 may be grounded, or may be electrically floating. Alternatively, a constant voltage may be applied to the first electrode 210, the second electrode 220, and the fourth electrode 240. In particular, 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.

[0241] Fig.16 is a diagram illustrating separation areas according to some embodiments of the present disclosure.

[0242] refer to Figure 6 and Fig.16 The sensing region 200A of the sensor layer 200 may include a plurality of separation regions DVA defined in the first direction DR1. For example, the plurality of separation regions DVA may include a first outer separation region DVA1, a central separation region DVA2, and a second outer separation region DVA3.

[0243] According to some embodiments of the present disclosure, at least one of the gain and weight applied to each of the signals received from the second electrode 220 can be changed according to the effective area in the partition area DVA in which the pen PN is located. For example, according to the effective area, at least one of the gain and weight applied to each of the signals received from the first electrode group 220G1 located above the boundary RIL can be adjusted; at least one of the gain and weight applied to each of the signals received from the second electrode group 220G2 located below the boundary RIL can be adjusted; and at least one of the gain and weight applied to each of the signals received from the first electrode group 220G1 and at least one of the gain and weight applied to each of the signals received from the second electrode group 220G2 can be adjusted.

[0244] Fig.17 is a diagram for describing the second mode MD2 (particularly, the pre-pen sensing driving mode PSS) according to some embodiments of the present disclosure.

[0245] refer to Figure 4 , Fig.16 and Fig.17 The second mode MD2 may include a pre-pen sensing driving mode PSS (see Fig. 12B ). refer to Fig.17 In the pre-pen sensing driving mode PSS, the sensor driver 200C may be configured to detect an effective area in which the pen PN is located from among the partition areas DVA based on a signal received from the sensor layer 200. The partition areas DVA are sequentially defined in the first direction DR1. Therefore, the effective area may be detected based on a position in the first direction DR1.

[0246] According to some embodiments of the present disclosure, the sensor driver 200C may receive a first reception signal PRX1 from the first electrode 210, and may detect an effective area based on the first reception signal PRX1. In other words, in the pre-pen sensing driving mode PSS, the second electrode 220 may not receive a signal. In this case, the current consumption of the electronic device 1000 may be reduced.

[0247] The sensor driver 200C is configured to change at least one of the gain and weight applied to each of the first electrode group 220G1 and the second electrode group 220G2 according to the position of the effective area. For example, at least one of the gain and weight can be adjusted so as to reduce or eliminate the sensitivity difference between the signals received from the second electrode 220 and the signals received from the second electrode 220 adjacent to the boundary RIL where the wiring direction changes. Therefore, the phenomenon of reduced coordinate accuracy due to the sensitivity difference can be alleviated or eliminated. In other words, the sensitivity difference according to the change in the wiring direction can be corrected, thereby improving the pen detection accuracy.

[0248] According to some embodiments of the present disclosure, the sensor driver 200C may receive signals, ie, receive signals, from both the first electrode 210 and the second electrode 220. Then, the sensor driver 200C may detect the effective area based on the received signals.

[0249] Fig.18 is a diagram illustrating a sensor driver 200C according to some embodiments of the present disclosure.

[0250] refer to Fig.17 and Fig.18 , a sensor driver 200C, one second electrode 220-1a, and another second electrode 220-2a are shown. One second electrode 220-1a may be included in the first electrode group 220G1, and another second electrode 220-2a may be included in the second electrode group 220G2.

[0251] The sensor driver 200C may include a charging voltage amplifier AP, a first variable capacitor VC1, a first variable resistor VR1, a second variable capacitor VC2, a second variable resistor VR2, a current transmitter CC, and an analog-to-digital converter ADC. The components included in the sensor driver 200C are not limited to the components described above. At least some of the components described above may be omitted, and other components may be added. In addition, the connection order of the components included in the sensor driver 200C may also be changed. For example, the current transmitter CC may be placed between the charging voltage amplifier AP and one second electrode 220-1a and between the charging voltage amplifier AP and another second electrode 220-2a.

[0252] According to some embodiments of the present disclosure, one second electrode 220-1a may be electrically connected to an inverting terminal of a charging voltage amplifier AP. Another second electrode 220-2a may be electrically connected to a non-inverting terminal of the charging voltage amplifier AP. For example, two second electrodes 220-1a and 220-2a adjacent to each other or spaced apart by a distance (e.g., a set or predetermined distance) may be electrically connected to the charging voltage amplifier AP.

[0253] According to some embodiments of the present disclosure, each of the first variable capacitor VC1 and the first variable resistor VR1 can be connected in parallel to the inverting terminal and the output terminal of the charging voltage amplifier AP. Each of the second variable capacitor VC2 and the second variable resistor VR2 can be connected in parallel to the non-inverting terminal and the output terminal of the charging voltage amplifier AP.

[0254] According to some embodiments of the present disclosure, the sensor driver 200C can adjust the gain by adjusting at least one of the first variable capacitor VC1, the first variable resistor VR1, the second variable capacitor VC2, and the second variable resistor VR2. For example, the first capacitor CM1 and the first resistor RT1 can be defined (formed or set) in one second electrode 220-1a. The second capacitor CM2 and the second resistor RT2 can be defined in another second electrode 220-2a.

[0255] The gain of one second electrode 220-1a may correspond to the minimum value of the ratio of the first capacitor CM1 / first variable capacitor VC1 and the first variable resistor VR1 / first resistor RT1. In addition, the gain of another second electrode 220-2a may correspond to the minimum value of the ratio of the second capacitor CM2 / second variable capacitor VC2 and the second variable resistor VR2 / second resistor RT2.

[0256] According to some embodiments of the present disclosure, a first signal RXSa received from one second electrode 220-1a and a second signal RXSb received from another second electrode 220-2a may be amplified with different gain values. Therefore, at least one of the gain and the weight may be adjusted so as to reduce or eliminate the sensitivity difference between the signals received from the second electrodes 220-1a and 220-2a adjacent to the boundary RIL where the wiring direction changes. Therefore, the phenomenon that the coordinate accuracy may be reduced due to the sensitivity difference may be reduced or eliminated.

[0257] The signal output from the charging voltage amplifier AP may be provided to the current conveyor CC. For example, the signals of two channels having different wiring directions from each other (e.g., a first signal RXSa received from one second electrode 220-1a and a second signal RXSb received from another second electrode 220-2a) may be opposite to each other. Therefore, the current conveyor CC may process the signal output from the charging voltage amplifier AP for differential sensing.

[0258] The analog-to-digital converter ADC may receive a signal provided from the current conveyor CC. The analog-to-digital converter ADC may sample a maximum value point of the received signal and may convert the sampling result into a digital signal. The analog-to-digital converter ADC may output a code CHD for converting an analog signal into a digital signal.

The components included in the sensor driver 200Ca are not limited to the components described above. At least some of the components described above may be omitted, and other components may be added.

[0262] According to some embodiments of the present disclosure, one second electrode 220-1a may be electrically connected to the inverting terminal of the first charging voltage amplifier APa, and the reference voltage V_Ref may be provided to the non-inverting terminal of the first charging voltage amplifier APa. Another second electrode 220-2a may be electrically connected to the inverting terminal of the second charging voltage amplifier APb, and the reference voltage V_Ref may be provided to the non-inverting terminal of the second charging voltage amplifier APb. According to some embodiments of the present disclosure, each of the first variable capacitor VCPa and the first variable resistor VRa may be connected in parallel to the inverting terminal and the output terminal of the first charging voltage amplifier APa. Each of the second variable capacitor VCPb and the second variable resistor VRb may be connected in parallel to the inverting terminal and the output terminal of the second charging voltage amplifier APb.

[0263] According to some embodiments of the present disclosure, the sensor driver 200Ca can adjust the gain by adjusting at least one of the first variable capacitor VCPa, the first variable resistor VRa, the second variable capacitor VCPb, and the second variable resistor VRb. For example, the first capacitor CM1 and the first resistor RT1 can be defined (formed or set) in one second electrode 220-1a. The second capacitor CM2 and the second resistor RT2 can be defined in another second electrode 220-2a.

[0264] The gain of one second electrode 220-1a may correspond to the minimum value of the ratio of the first capacitor CM1 / first variable capacitor VCPa and the first variable resistor VRa / first resistor RT1. In addition, the gain of another second electrode 220-2a may correspond to the minimum value of the ratio of the second capacitor CM2 / second variable capacitor VCPb and the second variable resistor VRb / second resistor RT2.

[0265] According to some embodiments of the present disclosure, a first signal RXSa received from one second electrode 220-1a and a second signal RXSb received from another second electrode 220-2a can be amplified with different gain values. Therefore, at least one of the gain and the weight can be adjusted so as to reduce or eliminate the sensitivity difference between the signals received from the second electrodes 220-1a and 220-2a adjacent to the boundary RIL where the wiring direction changes. Therefore, the phenomenon of reduced coordinate accuracy due to the sensitivity difference can be alleviated or eliminated.

[0266] The signals output from the first charging voltage amplifier APa and the second charging voltage amplifier APb may be provided to the intermediate circuit AC. The intermediate circuit AC may be a circuit composed of passive elements. For example, each of the intermediate circuits AC may include a low-pass filter, and the low-pass filter may include a resistor and a capacitor.

[0267] The signal output from the intermediate circuit AC can be output to the first analog-to-digital converter ADCa and the second analog-to-digital converter ADCb.

The first analog-to-digital converter ADCa can output the first data DT1. The second analog-to-digital converter ADCb can output the second data DT2.

[0268] The difference calculator DCC may receive the first data DT1 and the second data DT2.

Alternatively, when the signals of the first data DT1 and the second data DT2 are different from each other, the difference calculator DCC may output a code CHD based on the sum of the first data DT1 and the second data DT2.

[0269] Fig. 20 is a diagram illustrating a sensor driver 200Cb according to some embodiments of the present disclosure.

[0270] refer to Fig.17 and Fig. 20 , a sensor driver 200Cb, one second electrode 220 - 1 a , and another second electrode 220 - 2 a are shown.

[0271] The sensor driver 200Cb may include a first charging voltage amplifier APa and a second charging voltage amplifier APb, a first capacitor CPa, a second capacitor CPb, an intermediate circuit AC, a first analog-to-digital converter ADCa, a second analog-to-digital converter ADCb, and a difference calculator DCC. The components included in the sensor driver 200Cb are not limited to the components described above. At least some of the components described above may be omitted, and other components may be added.

[0272] According to some embodiments of the present disclosure, the first capacitor CPa may be connected in parallel to the inverting terminal and the output terminal of the first charging voltage amplifier APa. The second capacitor CPb may be connected in parallel to the inverting terminal and the output terminal of the second charging voltage amplifier APb. The first capacitor CPa and the second capacitor CPb may have an invariable capacitance, and the gain of each of the first charging voltage amplifier APa and the second charging voltage amplifier APb may be fixed.

[0273] The signals output from the first charging voltage amplifier APa and the second charging voltage amplifier APb may be provided to the intermediate circuit AC. Each of the intermediate circuits AC may include a low-pass filter, and the low-pass filter may include a resistor and a capacitor. The signal output from the intermediate circuit AC may be output to the first analog-to-digital converter ADCa and the second analog-to-digital converter ADCb.

[0274] According to some embodiments of the present disclosure, a first weight GA1 may be applied to the first data DT1a, and a second weight GA2 may be applied to the second data DT2a. The first data DT1a generated by the first signal RXSa received from one second electrode 220-1a and the second data DT2a generated by the second signal RXSb received from another second electrode 220-2a may be adjusted because different weights are applied. Therefore, the weights may be adjusted so as to reduce or eliminate the sensitivity difference between the signals received from the second electrodes 220-1a and 220-2a adjacent to the boundary RIL where the wiring direction changes. Therefore, the phenomenon of reduced coordinate accuracy due to the sensitivity difference may be alleviated or eliminated.

[0276] Fig.21 is a diagram showing a sensor driver 200Cc according to some embodiments of the present disclosure. Fig.21 In the description of Fig.19 and Fig. 20 The same components are described herein, and thus some repeated descriptions of the same or similar components may be omitted to avoid redundancy.

[0277] refer to Fig.17 and Fig.21 , a sensor driver 200Cc, one second electrode 220 - 1 a , and another second electrode 220 - 2 a are shown.

[0278] The sensor driver 200Cc includes first and second charging voltage amplifiers APa and APb, a first variable capacitor VCPa, a first variable resistor VRa, a second variable capacitor VCPa, a second variable resistor VRb, an intermediate circuit AC, a first analog-to-digital converter ADCa, a second analog-to-digital converter ADCb and a difference calculator DCC.

[0279] According to some embodiments of the present disclosure, the sensor driver 200Cc may adjust the gain by adjusting at least one of the first variable capacitor VCPa, the first variable resistor VRa, the second variable capacitor VCPb, and the second variable resistor VRb. In addition, the first weight GA1 may be applied to the first data DT1b output from the first analog-to-digital converter ADCa. The second weight GA2 may be applied to the second data DT2b output from the second analog-to-digital converter ADCb.

[0280] According to some embodiments of the present disclosure, a first signal RXSa received from one second electrode 220-1a and a second signal RXSb received from another second electrode 220-2a can be amplified with different gain values, and different weights can be applied. Therefore, at least one of the gain and the weight can be adjusted so as to reduce or eliminate the sensitivity difference between the signals received from the second electrodes 220-1a and 220-2a adjacent to the boundary RIL where the wiring direction changes. Therefore, the phenomenon of reduced coordinate accuracy caused by the sensitivity difference can be alleviated or eliminated.

[0281] Fig. 22 is a graph showing gain values ​​corresponding to channels according to some embodiments of the present disclosure. Fig.23 is a graph showing gain values ​​corresponding to channels according to some embodiments of the present disclosure.

[0282] refer to Figure 4 , Figure 6 , Fig. 22 and Fig.23 , the gain value applied to the signal received from the channel (e.g., the first electrode 210, the first electrode group 220G1, and the second electrode group 220G2) can be stored in a memory within the sensor driver 200C or in a memory that communicates with the sensor driver 200C, but is not particularly limited to this according to the embodiments of the present disclosure.

[0283] exist Fig. 22 , the gain value corresponding to the channel before the pre-pen sensing driving mode PSS (e.g., before the effective area in which the detection pen PN is located) is described. For example, the gain value applied to the signal received from the first electrode 210 may be GAIN_A, and the gain value applied to the signal received from the first electrode group 220G1 and the second electrode group 220G2 among the second electrodes 220 may be GAIN_B.

[0284] Then, when it is detected that the active area in which the pen PN is located, the gain value of at least one of the first electrode group 220G1 and the second electrode group 220G2 may be adjusted according to the position of the active area. Fig.23 An example of a gain value adjusted according to an effective area is shown in FIG. Fig.23 The gain adjustment mode or amount shown in .

[0285] refer to Fig.23 , the gain value applied to the signal received from the first electrode 210 may be maintained as GAIN_A without change. In addition, when the active area is the central partition area DVA2, the gain value applied to the signal received from the first electrode group 220G1 and the second electrode group 220G2 may be maintained as GAIN_B.

[0286] When the effective area is the first external separation area DVA1, the gain value applied to the signal received from the first electrode group 220G1 can be changed from GAIN_B to GAIN_1, and the gain value applied to the signal received from the second electrode group 220G2 can be maintained at GAIN_B. When the effective area is the second external separation area DVA3, the gain value applied to the signal received from the first electrode group 220G1 can be maintained at GAIN_B, and the gain value applied to the signal received from the second electrode group 220G2 can be changed from GAIN_B to GAIN_2. Each of GAIN_1 and GAIN_2 can have a value greater than GAIN_B. GAIN_1 and GAIN_2 can have values ​​that can reduce the deviation of sensitivity. GAIN_1 and GAIN_2 can be the same as each other or can be different from each other.

[0287] exist Fig. 22 and Fig.23 , adjusting the gain is described as an example, but the description can be substantially equally applied to reference Fig. 20 The weights can be the same as the weights from the analog-to-digital converter ADCa or ADCb (see Fig. 20 ) output data DT1a or DT2a (see Fig. 20 ) multiplied by. For example, when the effective area is the first external separation area DVA1, the weight applied to the signal received from the first electrode group 220G1 can be increased, and the weight applied to the signal received from the second electrode group 220G2 can be maintained. When the effective area is the second external separation area DVA3, the weight applied to the signal received from the first electrode group 220G1 can be maintained, and the weight applied to the signal received from the second electrode group 220G2 can be increased. When the weight is adjusted, the data difference caused by the sensitivity difference can be reduced. Therefore, the phenomenon of reduced coordinate accuracy due to the sensitivity difference can be relatively alleviated or eliminated.

[0288] According to some embodiments of the present disclosure, the first gains applied to the signals received from some second electrodes 220-1 included in the first electrode group 220G1 may be the same as each other. Alternatively, the first weights applied to the signals received from the second electrodes 220-1 may be the same as each other. In addition, the second gains applied to the signals received from some of the other second electrodes 220-2 included in the second electrode group 220G2 may be the same as each other. Alternatively, the second weights applied to the signals received from the other second electrodes 220-2 may be the same as each other.

[0289] When the pen PN is located in the central partition area DVA2, the first gain may be the same as the second gain, and the first weight may be the same as the second weight. When the pen PN is located in the first outer partition area DVA1 or the second outer partition area DVA3, the first gain may be different from the second gain. When the pen PN is located in the first outer partition area DVA1 and the second outer partition area DVA3, the first weight may be different from the second weight.

[0290] Fig.24A is a diagram for describing a second mode MD2 according to some embodiments of the present disclosure. Fig. 24B is a diagram for describing a second mode MD2 based on a sensing unit SU according to some embodiments of the present disclosure.

[0291] refer to Figure 4 , Fig.24A and Fig. 24B , the second mode MD2 may include a charging driving mode SCC and a pen sensing driving mode SS. Fig.24A and Fig. 24B is a diagram for describing the pen sensing driving mode SS. Fig. 24B 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.

[0292] The RLC resonant circuit of the pen PN may emit a magnetic field at a resonant frequency while discharging the charged charge. Due to 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 also be generated in the second auxiliary electrode 240s of the fourth electrode 240.

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.

[0295] The sensor driver 200C may receive a first reception signal PRX1a from the first electrode 210, and may receive a second reception signal PRX2a from the second electrode 220. In this case, all ends of the third electrode 230 and the fourth electrode 240 may be floated. Therefore, the compensation of the sensing signal may be maximized by coupling between the first electrode 210 and the third electrode 230 and by coupling between the second electrode 220 and the fourth electrode 240. In addition, the other ends of the third electrode 230 and the fourth electrode 240 may be grounded or floated. Therefore, by coupling between the first electrode 210 and the third electrode 230 and by coupling between the second electrode 220 and the fourth electrode 240, the third induced current Ic and the fourth induced current Id may be fully transmitted to the first electrode 210 and the second electrode 220.

[0296] According to some embodiments of the present disclosure, the wiring directions of the electrodes and auxiliary electrodes in the sensor layer 200 where the layers overlap may be different. For example, the wiring direction of the first electrode 210 may be different from the wiring direction of the first auxiliary electrode 230s. In addition, the wiring direction of the second electrode 220 may be different from the wiring direction of the second auxiliary electrode 240s. For example, in Fig. 24B , the first electrode 210 and the first trace 210t may be connected in the lower portion of the sensing unit SU. The first auxiliary electrode 230s and the third trace 230rt1 may be connected in the upper portion of the sensing unit SU. The second electrode 220 and the second trace 220t may be connected on the right side of the sensing unit SU. The second auxiliary electrode 240s and the fourth trace 240t may be connected on the left side of the sensing unit SU.

[0298] refer to Fig.24A and Fig.25 , one channel CH-rx may include a second electrode 220-2 and a second auxiliary electrode 240s2 overlapping the second electrode 220-2. For example, when the Fig.24A), the second electrode 220 and the second auxiliary electrode 240s2 may overlap each other when viewed from above (eg, in a plan view). The second electrode 220-2 may output a second reception signal PRX2a to the sensor driver 200C, and the second auxiliary electrode 240s2 may be connected to the second electrode 220-2 in a coupling method.

[0299] According to some embodiments of the present disclosure, in the pen sensing driving mode SS, the second auxiliary electrode 240s2 may be electrically connected to the ground. For example, the fourth pad PD4 electrically connected to the second auxiliary electrode 240s2 may be grounded. That is, the second auxiliary electrode 240s2 may be directly connected to the ground through the fourth trace 240t-2 and the fourth pad PD4.

[0300] A plurality of coupling capacitors Ccp may be defined between the second electrode 220-2 and the second auxiliary electrode 240s2. In the pen sensing mode, the sensor driver 200C may receive a sense current flowing from the second auxiliary electrode 240s2 to the second electrode 220-2 through the coupling capacitors Ccp.

[0303] A plurality of coupling capacitors Ccp11, Ccp12, Ccp13, and Ccp14 may be defined between the second electrode 220-2 and the second auxiliary electrode 240s2. In addition, capacitors Cbc1, Cbc2, Cbc3, and Cbc4 are defined in the second electrode 220-2. Capacitors Cbc1, Cbc2, Cbc3, and Cbc4 may be referred to as "parasitic capacitors" or "base capacitors".

[0304] The input terminal IT may correspond to one pad (eg, second pad PD2) electrically connected between the sensor driver 200C and the second electrode 220-2. One end of the second auxiliary electrode 240s2 may be electrically connected to the fourth trace 240t-2. The other end of the second auxiliary electrode 240s2 may float.

[0305] refer to Fig.26A , when the pen PN approaches a channel CH-rx, a first induced electromotive force Vs(t) may be generated in the second electrode 220-2 by a magnetic field generated by the pen PN, and a second induced electromotive force Va(t) may be generated in the second auxiliary electrode 240s2. The first induced current IN-M and the third induced current IN-B may be generated by the first induced electromotive force Vs(t), and the 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.

[0306] For example, it is assumed that the capacitance of each of the capacitors Cbc1 , Cbc2 , Cbc3 , and Cbc4 is Cb, and it is assumed that the capacitance of each of the coupling capacitors Ccp11 , Ccp12 , Ccp13 , and Ccp14 is Cc.

[0307] The time-varying first induction current IN-M can be expressed by the following formula.

[0308]

[0309] The second induction current IN-A that varies with time can be expressed by the following formula.

[0310]

[0311] The third induction current IN-B that varies with time can be expressed by the following formula.

[0312]

[0313] The first induced current IN-M may be an induced current caused by at least a portion 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 at the first electrode 210 may be referred to as a "first auxiliary induced current". 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 caused by at least a portion of the coupling capacitors Ccp11, Ccp12, Ccp13, and Ccp14, and may be referred to as a "coupled induced current".

[0314] refer to Fig.26B, when the pen PN approaches one channel CH-rx, a first induced electromotive force Vs(t) may be generated in the second electrode 220-2 by a magnetic field generated by the pen PN, and a second induced electromotive force Va(t) may be generated in the second auxiliary electrode 240s2. Since all voltages at both ends of each of the capacitors Cbc1, Cbc2, and Cbc3 placed between the first induced electromotive force Vs(t) and the input terminal IT are grounded, current may not flow through the capacitors Cbc1, Cbc2, and Cbc3.

[0315] 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.

[0316] For example, it is assumed that the capacitance of each of the capacitors Cbc1 , Cbc2 , Cbc3 , and Cbc4 is Cb, and it is assumed that the capacitance of each of the coupling capacitors Ccp11 , Ccp12 , Ccp13 , and Ccp14 is Cc.

[0317] The time-varying first induction current IF-M can be expressed by the following formula.

[0318]

[0319] The second induction current IF-A that varies with time can be expressed by the following formula.

[0320]

[0321] The third induction current IF-B that varies with time can be expressed by the following formula.

[0322]

[0323] The second induced current IF-A and the third induced current IF-B generated in the second auxiliary electrode 240s2 may be additionally generated by the coupling capacitors Ccp11, Ccp12, Ccp13, and Ccp14. Therefore, the total induced current IF may be increased compared to the case where the second auxiliary electrode 240s2 does not exist, and the total induced current IF may be large enough to sense the input of the pen PN.

[0324] Fig. 27 is a diagram schematically illustrating four channels CH-rxa according to some embodiments of the present disclosure. Fig.28A is an equivalent circuit diagram showing the relationship between one channel CH-rxa and the pen PN according to some embodiments of the present disclosure. Fig.28B is an equivalent circuit diagram showing the relationship between one channel CH-rxa and the pen PN according to some embodiments of the present disclosure.

[0325] refer to Fig.24A and Fig. 27 , one channel CH-rxa may include a second electrode 220-2 and an edge capacitor Ceg electrically connected to the second electrode 220-2. In the pen sensing driving mode SS, all the second electrodes 220-2 may be electrically connected to one terminal 220TM through the edge capacitor Ceg. The terminal 220TM may be grounded, or a bias voltage may be applied to the terminal 220TM.

[0326] refer to Fig. 27 and Fig.28A , one channel CH-rxa may include one second electrode 220-2 connected to the input terminal IT. The input terminal IT may correspond to a pad electrically connected between the sensor driver 200C and the second electrode 220-2.

[0327] Capacitors Cbc1, Cbc2, Cbc3, and Cbc4 are defined in the second electrode 220-2. Capacitors Cbc1, Cbc2, Cbc3, and Cbc4 may be referred to as "parasitic capacitors" or "base capacitors". In addition, the second electrode 220-2 may be electrically connected to a fringe capacitor Ceg-t. According to some embodiments of the present disclosure, the capacitance of the fringe capacitor Ceg-t may be greater than the capacitance of each of the capacitors Cbc1, Cbc2, Cbc3, and Cbc4.

[0328] refer to Fig.28A , when the pen PN approaches a channel CH-rxa, a first induced electromotive force Vs(t) may be generated in the second electrode 220-2 by the magnetic field generated by the pen PN. Therefore, an induced current INa may be generated in a channel CH-rxa. One of the non-inverting terminal and the inverting terminal of the charging voltage amplifier may be electrically connected to the input terminal IT, and the other thereof may be grounded. In this case, it is recognized that the input terminal IT is grounded. Therefore, all voltages on both ends of the capacitor Cbc1 among the capacitors Cbc1, Cbc2, Cbc3, and Cbc4 are grounded, and thus current may not flow into the capacitor Cbc1.

[0329] Assuming that the capacitance of each of the capacitors Cbc2 , Cbc3 , and Cbc4 is Cb, and the capacitance of the fringe capacitor Ceg-t is Ce, the time-varying induced current INa can be expressed by the following formula.

[0330]

[0331] refer to Fig.28B , when the pen PN is close to a channel CH-rxa, an induced current IFa may be generated in a channel CH-rxa by a magnetic field generated by the pen PN. All voltages across each of the first capacitor Cbc1, the second capacitor Cbc2, and the third capacitor Cbc3 among the capacitors Cbc1, Cbc2, Cbc3, and Cbc4 are grounded, and thus current may not flow through the capacitors Cbc1, Cbc2, and Cbc3. Assuming that the capacitance of the capacitor Cbc4 is Cb and the capacitance of the edge capacitor Ceg-t is Ce, the induced current IFa that varies with time may be expressed by the following formula.

[0332]

[0333] refer to Fig.28A and Fig.28B , the current intensity can be improved by the edge capacitor Ceg-t. Therefore, compared with the case where the edge capacitor Ceg-t does not exist, the total induced current IFa can be increased, and the total induced current IFa can be large enough to sense the input of the pen PN.

[0334] Fig.29 is a graph GP showing the current intensity according to the position of the pen PN for one channel.

[0335] refer to Fig.29 , the first point PP1 can be compared with Fig.26A and Fig.28A The position of the pen PN shown in FIG. 1 corresponds to the position of the pen PN shown in FIG. 1 , and the second point PP2 can correspond to the position of the pen PN shown in FIG. 1 . Fig.26B and Fig.28B Corresponding to the position of the pen PN shown in .

[0336] As reference Fig.25 and Fig.26B As described, the second sensing current IF-A and the third sensing current IF-B generated in the second auxiliary electrode 240s2 may be additionally generated by the coupling capacitors Ccp11, Ccp12, Ccp13, and Ccp14. Therefore, the total sensing current IF may be increased, and the total sensing current IF may be large enough to sense the input of the pen PN.

[0337] As reference Fig. 27 and Fig.28B As described above, the total capacitance can be compensated (or improved) by the fringe capacitor Ceg-t. Therefore, the total sensing current IFa can be increased, and the total sensing current IFa can be large enough to sense the input of the pen PN.

[0338] Fig.30 is a graph showing sensitivities according to positions of a plurality of channels according to a comparative example.

[0341] refer to Fig.30 , it can be identified that because the gain and weight are not adjusted, the sensitivity changes rapidly based on the boundary RIL. In this case, the coordinate accuracy based on the boundary RIL may be relatively reduced or undesirable. According to some embodiments of the present disclosure, the effective area can be detected, and at least one of the gain and weight can be adjusted accordingly. Therefore, the degree to which the sensitivity changes at the boundary RIL can be relatively mitigated or eliminated.

The first graph GP-DVA1 may correspond to a sensitivity change according to a first track P-MT1 in a first outer partition area DVA1, and the second graph GP-DVA3 may correspond to a sensitivity change according to a second track P-MT2 in a second outer partition area DVA3.

[0344] At least one of the gain and the weight can be adjusted to adjust the sensitivity of the signal received from the first electrode group 220G1 and the second electrode group 220G2 divided based on the boundary RIL so that the sensitivities are substantially the same as each other or the difference between the sensitivities is reduced. Therefore, even at the boundary RIL, the sensitivity can be adjusted by using the same (or substantially the same) slope, thereby relatively improving the coordinate detection accuracy.

[0345] Fig.32 is a graph showing gain values ​​corresponding to channels according to some embodiments of the present disclosure. Fig.33 is a graph showing sensitivity of pen position according to multiple channels according to some embodiments of the present disclosure.

[0346] refer to Figure 6 , Fig.32 and Fig.33 , a gain applied to a signal received from the second electrode 220-1 included in the first electrode group 220G1 and a gain applied to a signal received from the second electrode 220-2 included in the second electrode group 220G2 may be determined.

[0347] For example, when the active area is the first outer separation area DVA1, the gain values ​​applied to the signals received from the second electrode 220-1 and the second electrode 220-2 may be determined as GAIN_1a, GAIN_1b, GAIN_1c, and GAIN_1d, respectively. GAIN_1a, GAIN_1b, GAIN_1c, and GAIN_1d may be different from each other; some of GAIN_1a, GAIN_1b, GAIN_1c, and GAIN_1d may be the same as each other; and some of GAIN_1a, GAIN_1b, GAIN_1c, and GAIN_1d may be different from each other. For example, GAIN_1a may be the largest, and GAIN_1d may be the smallest. When the active area is the central separation area DVA2, the gain values ​​applied to the signals received from the second electrode 220-1 and the second electrode 220-2 may be determined as GAIN_2a, GAIN_2b, GAIN_2c, and GAIN_2d, respectively. GAIN_2a, GAIN_2b, GAIN_2c, and GAIN_2d may be different from each other; some of GAIN_2a, GAIN_2b, GAIN_2c, and GAIN_2d may be the same as each other; and some of GAIN_2a, GAIN_2b, GAIN_2c, and GAIN_2d may be different from each other. When the effective area is the second outer partition area DVA3, the gain values ​​applied to the signals received from the second electrode 220-1 and the second electrode 220-2 may be determined as GAIN_3a, GAIN_3b, GAIN_3c, and GAIN_3d, respectively. GAIN_3a, GAIN_3b, GAIN_3c, and GAIN_3d may be different from each other; some of GAIN_3a, GAIN_3b, GAIN_3c, and GAIN_3d may be the same as each other; and some of GAIN_3a, GAIN_3b, GAIN_3c, and GAIN_3d may be different from each other.

[0349] According to some embodiments of the present disclosure, at least one of the gain and the weight may be determined with respect to the signal received from the second electrode 220-1 and the second electrode 220-2. Therefore, the sensitivity of the signal received from the first electrode group 220G1 and the second electrode group 220G2 may be substantially the same as each other, and the sensitivity difference according to the distance may also be eliminated. Therefore, both the sensitivity difference according to the change in the wiring direction and the sensitivity difference according to the pen position are corrected, thereby relatively improving the pen detection accuracy.

[0350] Fig.34 is a diagram illustrating a separation area DVAa according to some embodiments of the present disclosure.

[0351] refer to Figure 6 and Fig.34 The sensing region 200A of the sensor layer 200 may include a plurality of separation regions DVAa defined in the first direction DR1. For example, the plurality of separation regions DVAa may include a first outer separation region DVA1a, a second outer separation region DVA2a, a central separation region DVA3a, a third outer separation region DVA4a, and a fourth outer separation region DVA5a.

[0352] According to some embodiments of the present disclosure, at least one of the gain and weight applied to each of the signals received from the second electrode 220 can be changed according to the effective area in which the pen PN in the partition area DVAa is located. For example, according to the effective area, at least one of the gain and weight applied to each of the signals received from the first electrode group 220G1 located above the boundary RIL can be adjusted; at least one of the gain and weight applied to each of the signals received from the second electrode group 220G2 located below the boundary RIL can be adjusted; and at least one of the gain and weight applied to each of the signals received from the first electrode group 220G1 and at least one of the gain and weight applied to each of the signals received from the second electrode group 220G2 can be adjusted.

[0353] According to some embodiments of the present disclosure, when the effective area is far away from the wiring area, at least one of the gain and the weight can be increased. Figure 6 and Fig.34, in the first electrode group 220G1, the weight applied when the active area is the first external partition area DVA1a may be greater than the weight applied when the active area is the fourth external partition area DVA5a. In addition, in the second electrode group 220G2, the weight applied when the active area is the first external partition area DVA1a may be less than the weight applied when the active area is the fourth external partition area DVA5a.

[0354] exist Fig.34 , it is described that the number of separation areas DVAa is 5. However, the number of separation areas DVAa is not limited to the examples described in this specification. For example, the number of separation areas DVAa may be two or more, or more than five, and may not be particularly limited thereto. That is, the number of separation areas DVAa may vary according to various embodiments, and any appropriate number of separation areas may be used according to the design of the display device.

[0355] Fig.35A is a graph showing current sensed at multiple channels according to some embodiments of the present disclosure. Fig.35B is a graph showing current obtained from a differential channel of a plurality of channels according to some embodiments of the present disclosure. Fig.35C is a diagram for describing a method for identifying a pen position according to some embodiments of the present disclosure.

[0356] refer to Figure 6 and Fig.35A , Fig.35A , the current sensed from the first electrode 210 or the second electrode 220 is shown in FIG. The first electrode 210 may correspond to the first channel, and the second electrode 220 may correspond to the second channel. In other words, Fig.35A is a graph showing the current sensed in the second channel, and Fig.35B is a graph showing the current obtained from the differential channel of the second channel.

[0357] refer to Fig.35A , the directions of the currents sensed from the second channels separated from each other and between which the portion where the pen PN is located may be different from each other. Therefore, based on the position of the pen PN, the direction of the current flowing into the channel on the left may be different from the direction of the current flowing into the channel on the right. Therefore, the sensor driver 200C can sense currents flowing in different directions based on the position of the pen PN. Fig.35B , the sensor driver 200C can sense the current by differentially sensing the channels adjacent to each other or the channels spaced apart from each other among the second channels. When the sensor driver 200C senses the current by using differential sensing, as shown in FIG. Fig.29 As shown in , the difference in current intensity according to the pen position for one channel can be compensated.

[0358] refer to Fig.35C , select points PTM, PTL, and PTR required for calculating the position coordinates of the pen PN from the sensing current value curve graph. Among the points PTM, PTL, and PTR, the point PTM of the maximum value of the sensing current value (also referred to as the maximum value point PTM), the n points PTL adjacent to the left side of the maximum value point PTM, and the n points PTR adjacent to the right side of the maximum value point PTM can be selected. n can be 1 or more. Fig.35C It is shown that n is 2. The sensor driver 200C can identify the y coordinate of the position of the pen PN from the selected points PTM, PTL, and PTR by using the centroid method. However, the embodiments according to the present disclosure are not particularly limited to this. For example, the sensor driver 200C can derive a trend line from the selected points PTM, PTL, and PTR, and can also calculate the y coordinate of the pen PN based on the maximum point of the trend line.

[0359] Although aspects of some embodiments of the present disclosure have been described for illustrative purposes, it will be understood by those skilled in the art that various modifications and substitutions may be made without departing from the scope and spirit of the embodiments of the present disclosure as disclosed in the attached claims and their equivalents. Therefore, the technical scope of the embodiments of the present disclosure is not limited to the detailed description of this specification, but should be limited by the claims and their equivalents.

[0360] As described above, the input of the pen and the touch input can be sensed by using the sensor layer. Because there is no need to add a separate component (e.g., a digitizer) for sensing the pen to the electronic device, the increase in thickness of the electronic device, the increase in weight of the electronic device, or the reduction in flexibility of the electronic device due to the addition of the digitizer may not occur. In addition, the sensor driver can be implemented so that at least one of the gain and weight applied to the signal received from the first electrode group and the second electrode group having different wiring directions from each other varies according to the position of the pen detected. Therefore, the sensitivity difference according to the change in the wiring direction can be corrected, thereby relatively improving the pen detection accuracy.

[0361] While aspects of some embodiments of the present disclosure have been described with reference to those embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications may be made to the disclosure without departing from the spirit and scope of the disclosure as set forth in the following claims and their equivalents.
