[0001] Cross-reference to related applications

[0002] This application claims priority and benefit to Korean Patent Application No. 10-2024-0055551, filed on April 25, 2024, with the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference. Technical Field

[0003] One aspect of the embodiments of this disclosure relates to electronic devices capable of sensing input made by a pen. Background Art

[0004] Multimedia electronic devices such as televisions (TVs), mobile phones, tablets, laptops, navigation systems, and game consoles include display devices for displaying images. In addition to general input methods such as buttons, keyboards, and mice, electronic devices may include a sensor layer (e.g., input sensors) capable of providing touch-based input methods, allowing users to easily and intuitively input information or commands. The sensor layer can sense the user's touch or pressure. For users accustomed to using writing instruments to input information or for specific applications (e.g., applications for drawing or drafting), the need for more detailed touch input using a pen is increasing.

[0069] In the following description, embodiments will be illustrated in more detail with reference to the accompanying drawings, in which similar reference numerals consistently denote similar elements. However, this disclosure may be implemented in a variety of different forms and should not be construed as being limited to the embodiments shown herein. Rather, these embodiments are provided as examples so that this disclosure will be thorough and complete, and will fully convey to those skilled in the art the aspects and features of this disclosure. Therefore, processes, elements, and techniques that are not essential for a person of ordinary skill in the art to a full understanding of the aspects and features of this disclosure may not be described. Unless otherwise stated, similar reference numerals denote similar elements throughout the drawings and written description, and therefore, redundant descriptions may not be repeated.

[0070] When a particular implementation can be carried out differently, the specific process sequence may differ from the described sequence. For example, two consecutively described processes may be performed simultaneously or substantially simultaneously, or they may be performed in the reverse order of the described sequence.

[0071] Furthermore, as will be understood by those skilled in the art, in view of the entirety of this disclosure, each suitable feature of the various embodiments of this disclosure may be combined in part or in whole, or combined with one another, and may be technically linked and operated in various suitable ways, and each embodiment may be implemented independently of one another or in combination with one another in any suitable way, unless otherwise stated or implied.

[0072] In the accompanying drawings, for clarity, the relative dimensions, thicknesses, and proportions of elements, layers, and regions may be exaggerated and / or simplified. For ease of illustration, spatial relative terms such as “below,” “under,” “below,” “below,” “above,” “upper,” etc., may be used herein to describe the relationship of one element or feature to another(s) as shown in the drawings. It will be understood that, in addition to the orientations depicted in the drawings, spatial relative terms are intended to encompass different orientations of the device in use or operation. For example, if the device in the drawings is flipped, an element described as “below,” “under,” or “below” other elements or features will consequently be oriented “above” other elements or features. Thus, the exemplary terms “below” and “below” can encompass both above and below orientations. The device may be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relative descriptive terms used herein should be interpreted accordingly.

[0073] Furthermore, it should be anticipated that the shapes shown in the accompanying drawings may vary in practice depending on, for example, tolerances and / or manufacturing techniques. Therefore, embodiments of this disclosure should not be construed as limited to the specific shapes shown in the drawings, and should be interpreted in light of possible changes in shape due to, for example, manufacturing processes. Consequently, the shapes shown in the drawings may not depict the actual shape of an area of ​​the device, and this disclosure is not limited thereto.

[0074] In the accompanying diagram, the x-axis, y-axis, and z-axis are not limited to the three axes of a Cartesian coordinate system and can be interpreted in a broader sense. For example, the x-axis, y-axis, and z-axis can be perpendicular or substantially perpendicular to each other, or they can represent different directions that are not perpendicular to each other.

[0075] It will be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or portions, these elements, components, regions, layers, and / or portions should not be limited by these terms. These terms are used to distinguish one element, component, region, layer, or portion from another element, component, region, layer, or portion. Therefore, without departing from the spirit and scope of this disclosure, the first element, first component, first region, first layer, or first portion described below may be referred to as a second element, second component, second region, second layer, or second portion.

[0076] It will be understood that when an element or layer is referred to as being "on," "connected to," or "attached to" another element or layer, it can be directly on, directly connected to, or directly attached to the other element or layer, or there can be one or more intervening elements or layers. Similarly, when a layer, area, or element is referred to as being "electrically connected" to another layer, area, or element, it can be directly electrically connected to the other layer, area, or element, and / or can be indirectly electrically connected with one or more intervening layers, areas, or elements between them. Furthermore, it will be understood that when an element or layer is referred to as being "between" two elements or layers, it can be the only element or layer between the two elements or layers, or there can be one or more intervening elements or layers.

[0077] The terminology used herein is for the purpose of describing particular embodiments and is not intended to limit this disclosure. As used herein, the singular forms “a” and “an” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that when the terms “comprises,” “comprising,” “includes,” “including,” “has,” “have,” and “having” are used in this specification, they specify the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. For example, the expression “A and / or B” means A, B, or A and B. When an expression such as “at least one of” follows an element in a column, it modifies the entire column and does not modify any individual element in that column. For example, the expressions “at least one of a, b and c” and “at least one of the group consisting of a, b and c” mean only a, only b, only c, both a and b, both a and c, both b and c, all of a, b and c, or variations thereof.

[0078] Terms such as "part" and "unit" can refer to software or hardware components that perform a specific function. Hardware components can include, for example, field-programmable gate arrays (FPGAs) or application-specific integrated circuits (ASICs). Software components can refer to executable code in addressable storage media and / or data used by the executable code. Therefore, software components can be, for example, object-oriented software components, class components, and task components, and can include processes, functions, attributes, procedures, subroutines, program code segments, drivers, firmware, microcode, data, databases, data structures, tables, arrays, or variables.

[0079] As used herein, the terms “substantially,” “about,” and similar terms are used as approximate terms and not as terms of degree, and are intended to account for inherent biases in measurements or calculations that would be recognized by one of ordinary skill in the art. Furthermore, when describing embodiments of this disclosure, the use of “may” means “one or more embodiments of this disclosure.” As used herein, the terms “use,” “using,” and “used” may be considered synonymous with the terms “utilize,” “utilizing,” and “utilized,” respectively.

[0080] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It will also be understood that terms, such as those defined in common dictionaries, shall be interpreted as having a meaning consistent with their meaning in the relevant field and / or the context of this specification, and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0081] Figure 1A This is a perspective view of an electronic device 1000 according to an embodiment of the present disclosure. Figure 1B This is a rear perspective view of an electronic device 1000 according to an embodiment of the present disclosure.

[0082] refer to Figure 1A and Figure 1B The electronic device 1000 can be a device activated by an electrical signal. For example, the electronic device 1000 can display an image and sense input applied from an external source. The external input can be user input. User input can include various suitable types of external input, such as a part of the user's body (e.g., human body), a pen, light, heat, or pressure.

[0083] 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 independent panels spaced apart from each other (e.g., separate). The first display panel DP1 may be referred to as the main display panel, and the second display panel DP2 may be referred to as the auxiliary display panel or the external display panel.

[0084] The first display panel DP1 may include a first display unit (e.g., a first display or a first touch display) DA1-F, and the second display panel DP2 may include a second display unit (e.g., a second display or a second touch display) DA2-F. The area of ​​the second display panel DP2 may be smaller than the area of ​​the first display panel DP1. For example, corresponding to (e.g., based on) the dimensions of the first display panel DP1 and the second display panel DP2, the area of ​​the first display unit DA1-F may be larger than the area of ​​the second display unit DA2-F.

[0085] In the unfolded state of the electronic device 1000, the first display unit DA1-F may have a plane parallel to or substantially parallel to the first direction DR1 and the second direction DR2. The thickness direction of the electronic device 1000 may be parallel to or substantially parallel to a third direction DR3 that intersects or intersects with the first direction DR1 and the second direction DR2. Therefore, the front surface (e.g., upper surface) and rear surface (e.g., lower surface) of the components constituting the electronic device 1000 may be defined based on the third direction DR3.

[0086] The first display panel DP1 or the first display unit DA1-F may include a foldable region FA that can be folded or unfolded, and a plurality of non-foldable regions NFA1 and NFA2 spaced apart from each other and interposed between the foldable region FA. The second display panel DP2 may overlap with one of the plurality of non-foldable regions NFA1 and NFA2. For example, the second display panel DP2 may overlap with the first non-foldable region NFA1.

[0087] The display orientation of a first image IM1a displayed on a portion of the first display panel DP1 (e.g., on a first non-folding region NFA1 or a second non-folding region NFA2) may be opposite to the display orientation of a second image IM2a displayed on the second display panel DP2. For example, the first image IM1a may be displayed on a third direction DR3, and the second image IM2a may be displayed on a fourth direction DR4, which is opposite to the third direction DR3.

[0088] In embodiments of this disclosure, the folding region FA can be bent relative to a folding axis that extends in a direction parallel to or substantially parallel to the long side of the electronic device 1000 (e.g., a direction parallel to or substantially parallel to the second direction DR2). In the folded state of the electronic device 1000, the folding region FA can have a curvature (e.g., a predetermined curvature) and a radius of curvature (e.g., a predetermined radius of curvature). The first non-folding region NFA1 and the second non-folding region NFA2 can face each other, and the electronic device 1000 can be folded inwards such that the first display unit DA1-F is not exposed to the outside.

[0089] In embodiments of this disclosure, the electronic device 1000 can be folded outwards, exposing the first display unit DA1-F to the outside. In embodiments of this disclosure, the electronic device 1000 can be folded either inwards or outwards from its unfolded state, but this disclosure is not limited thereto.

[0090] Figure 1A An exemplary illustration shows a folding region FA defined (e.g., set or included) in an electronic device 1000, but this disclosure is not limited thereto. For example, a plurality of folding axes and a plurality of corresponding folding regions may be defined in the electronic device, and the electronic device may fold inward or outward from each of the plurality of folding regions from an unfolded state.

[0091] According to embodiments of this disclosure, even when at least one of the first display panel DP1 and the second display panel DP2 does not include a digitizer, at least one of the first display panel DP1 and the second display panel DP2 can still sense input from the pen PN. Therefore, since the digitizer for sensing the pen PN can be omitted, the increase in thickness, weight, and reduction in flexibility of the electronic device 1000 that might have been caused by the addition of a digitizer can be avoided. Therefore, the second display panel DP2 and the first display panel DP1 can be designed to sense the pen PN.

[0092] Figure 2 This is a perspective view of an electronic device 1000-1 according to an embodiment of the present disclosure. Figure 3 This is a perspective view of an electronic device 1000-2 according to an embodiment of the present disclosure.

[0093] Figure 2 An exemplary embodiment shows that electronic device 1000-1 is a mobile phone, and electronic device 1000-1 may include a display panel DP. Figure 3 An exemplary embodiment shows that electronic device 1000-2 is a laptop computer, and electronic device 1000-2 may include a display panel (DP). Although Figure 3 It is a 3D diagram of electronic device 1000-2, but Figure 3 The coordinate axes included are displayed based on the display panel DP within the electronic device 1000-2.

[0094] In embodiments of this disclosure, the display panel DP can sense input applied from the outside (e.g., external input). External input can be user input. User input can include various suitable types of external input, such as a part of the user's body, a pen PN (e.g., see...). Figure 1A ), light, heat or pressure.

[0095] According to embodiments of this disclosure, the display panel DP can sense input from the pen PN even when the display panel DP does not include a digitizer. Therefore, since the digitizer for sensing the pen PN can be omitted, the increase in thickness and weight of the electronic device 1000-1 or 1000-2 that might have been caused by the addition of a digitizer can be avoided.

[0096] Figure 1A A foldable electronic device 1000 is shown as an example, and Figure 2 A strip-shaped electronic device 1000-1 is illustrated as an example, but the present disclosure is not limited thereto. For example, electronic devices according to some embodiments of the present disclosure may include rollable electronic devices, slidable electronic devices, stretchable electronic devices, etc.

[0097] Figure 4 This is a schematic cross-sectional view of a display panel DP according to an embodiment of the present disclosure.

[0099] Display layer 100 may be a component that generates or substantially generates an image. Display layer 100 may be a light-emitting display layer. For example, 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 light-emitting diode (LED) display layer, or a nano LED display layer. Display layer 100 may include a base layer 110, a circuit layer 120, a light-emitting element layer 130, and an encapsulation layer 140.

[0100] The base layer 110 may be a component providing a base surface on which the circuit layer 120 is disposed. The base layer 110 may have a multilayer structure or a single-layer structure. The base layer 110 may be a glass substrate, a metal substrate, a silicon substrate, a polymer substrate, etc., but this disclosure is not limited thereto.

[0101] Circuit layer 120 may be disposed on base layer 110. Circuit layer 120 may include insulating layers, semiconductor patterns, conductive patterns, signal lines, etc. Insulating layers, semiconductor layers and conductive layers may be formed on base layer 110 in a suitable manner (such as coating and deposition), and insulating layers, semiconductor layers and conductive layers may be selectively patterned by multiple photolithography processes.

[0102] The light-emitting element layer 130 may be disposed on the circuit layer 120. The light-emitting element layer 130 may include light-emitting elements. For example, the light-emitting element layer 130 may include organic light-emitting materials, inorganic light-emitting materials, organic-inorganic light-emitting materials, quantum dots, quantum rods, micro LEDs, or nano LEDs.

[0103] An encapsulation layer 140 may be disposed on the light-emitting element layer 130. The encapsulation layer 140 can protect the light-emitting element layer 130 from moisture, oxygen and foreign matter such as dust particles.

[0104] Sensor layer 200 may be disposed on display layer 100. Sensor layer 200 can sense external input applied from external units (e.g., external devices). Sensor layer 200 may be an integrated sensor formed continuously during the manufacturing process of display layer 100, or sensor layer 200 may be an external sensor attached to display layer 100. Sensor layer 200 may be referred to as a sensor, input sensing layer, input sensing panel, electronic device for sensing input coordinates, etc.

[0105] According to embodiments of this disclosure, the sensor layer 200 can sense both input from a passive input means, such as a user's body (e.g., a human body), and input from an input device that generates a magnetic field with an appropriate resonant frequency (e.g., a predetermined resonant frequency). The input device may be referred to as a pen, input pen, magnetic pen, stylus, or electromagnetic resonant pen.

[0106] Figure 5 This is a view showing the operation of an electronic device 1000 according to an embodiment of the present disclosure.

[0107] refer to Figure 5 The electronic device 1000 may include a display layer 100, a sensor layer 200, a display driving unit (e.g., a display driving circuit or a display driver) 100C, a sensor driving unit (e.g., a sensor driving circuit or a sensor driver) 200C, a main driving unit (e.g., a main driving circuit or a main driver) 1000C, and a power supply circuit 1000P.

[0108] Sensor layer 200 can sense a first input 2000 or a second input 3000 applied from an external unit (e.g., an external device). The first input 2000 and the second input 3000 can be input means that can provide a change in the capacitance of sensor layer 200, or they can be input means that can induce a current in sensor layer 200. For example, the first input 2000 can be a passive input means such as a user's body. The second input 3000 can be an input made by a pen PN or an input made by a radio frequency integrated circuit (RFIC) tag. For example, the pen PN can be a passive pen or an active pen.

[0109] In embodiments of this disclosure, the pen PN can be a device that generates a magnetic field having an appropriate resonant frequency (e.g., a predetermined resonant frequency). The pen PN can transmit output signals based on an electromagnetic resonance method. The pen PN can be referred to as an input device, input pen, magnetic pen, stylus, or electromagnetic resonant pen.

[0110] The PN can include an RLC resonant circuit, and the RLC resonant circuit can include an inductor L and a capacitor C. In embodiments of this disclosure, the RLC resonant circuit can be a variable resonant circuit with a variable resonant frequency. In this case, the inductor L can be a variable inductor, and / or the capacitor C can be a variable capacitor, but this disclosure is not limited thereto.

[0111] The inductor L generates current through a magnetic field formed in the electronic device 1000 (e.g., in the sensor layer 200). However, this disclosure is not particularly limited thereto. For example, when the pen PN operates as an active type, the pen PN can generate current even when it does not receive a magnetic field from an external unit. The generated current can be transferred to the capacitor C. The capacitor C charges the current input from the inductor L and discharges the charged current to the inductor L. Thereafter, the inductor L can emit a magnetic field with 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 as a received signal (e.g., a sensing signal) can be transferred to the sensor drive unit 200C.

[0112] The main drive unit 1000C can control the overall operation of the electronic device 1000. For example, the main drive unit 1000C can control the operation of the display drive unit 100C and the sensor drive unit 200C. The main drive unit 1000C may include at least one microprocessor and may also include a graphics controller. The main drive unit 1000C may be referred to as an application processor, a central processing unit, or a main processor.

[0113] The display driving unit 100C can drive the display layer 100. The display driving unit 100C can receive image data and control signals from the main driving unit 1000C. The control signals can include various suitable signals. For example, the control signals can include input vertical synchronization signals, input horizontal synchronization signals, master clock signals, data enable signals, etc.

[0114] The sensor driving unit 200C can drive the sensor layer 200. The sensor driving unit 200C can receive control signals from the main driving unit 1000C. The control signals may include a clock signal of the sensor driving unit 200C. In addition, the control signals may also include a mode determination signal that determines the driving mode of the sensor driving unit 200C and the sensor layer 200.

[0115] The sensor driving unit 200C can be implemented as an integrated circuit (IC) and can be electrically connected to the sensor layer 200. For example, the sensor driving unit 200C can be directly mounted on an area of ​​the display panel (e.g., a predetermined area), or it can be mounted on a separate printed circuit board using a chip-on-film (COF) method and electrically connected to the sensor layer 200.

[0116] The sensor driving unit 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 touch input (e.g., such as first input 2000). The second mode can be a mode for sensing input made by the pen PN (e.g., such as 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.

[0117] The switching between the first mode and the second mode can be performed in various suitable ways. For example, the sensor driving unit 200C and the sensor layer 200 can be driven in a time-division manner in the first mode and the second mode, and can sense the first input 2000 and the second input 3000. As another example, the switching between the first mode and the second mode can be generated by a user selection or a specific user action (e.g., input), either the first mode or the second mode can be activated or disabled by activating or disabling a specific application, or the current mode can be switched from one of the first mode and the second mode to the other. As another example, while the sensor driving unit 200C and the sensor layer 200 operate alternately in the first mode and the second mode, the first mode is maintained when the first input 2000 is sensed, or the second mode is maintained when the second input 3000 is sensed.

[0118] The sensor driving unit 200C can calculate the input coordinate information based on the signal received from the sensor layer 200, and can provide the main driving unit 1000C with the coordinate information. The main driving unit 1000C can perform an operation corresponding to the user's input based on the coordinate signal. For example, the main driving unit 1000C can operate the display driving unit 100C to display a new application image on the display layer 100.

[0119] The power supply circuit 1000P may include a power management integrated circuit (PMIC). The power supply circuit 1000P can generate multiple driving voltages for driving the display layer 100, sensor layer 200, display driving unit 100C, and sensor driving unit 200C. For example, the multiple driving voltages may include a gate high voltage, a gate low voltage, a first driving voltage (e.g., ELVSS voltage), a second driving voltage (e.g., ELVDD voltage), an initialization voltage, etc., but this disclosure is not particularly limited thereto.

[0120] Figure 6A This is a cross-sectional view of a display panel DP according to an embodiment of the present disclosure.

[0121] refer to Figure 6AAt least one buffer layer BFL may be formed on the upper surface of the base layer 110. The buffer layer BFL can improve the adhesion between the base layer 110 and the semiconductor pattern. The buffer layer BFL can be formed in multiple layers. As another example, the display layer 100 may also include a barrier layer. The buffer layer BFL may include at least one of silicon oxide, silicon nitride, and silicon oxide nitride. For example, the buffer layer BFL may include a structure in which silicon oxide layers and silicon nitride layers are alternately stacked or layered.

[0122] Semiconductor patterns SC, AL, DR, and SCL can be disposed on the buffer layer BFL. The semiconductor patterns SC, AL, DR, and SCL can comprise polycrystalline silicon. However, this disclosure is not limited thereto, and the semiconductor patterns SC, AL, DR, and SCL can comprise amorphous silicon, low-temperature polycrystalline silicon, or oxide semiconductors.

[0123] Figure 6A Some of the semiconductor patterns SC, AL, DR, and SCL are shown, and semiconductor patterns can also be arranged in other regions. The semiconductor patterns SC, AL, DR, and SCL can be arranged across pixels according to appropriate rules (e.g., specific rules). Depending on whether the semiconductor patterns SC, AL, DR, and SCL are doped, they can have different electrical properties. The semiconductor patterns SC, AL, DR, and SCL can include a first region SC, DR, and SCL with high conductivity and a second region AL with low conductivity. The first region SC, DR, and SCL can be doped with N-type or P-type dopant. A P-type transistor can include a doped region doped with P-type dopant, and an N-type transistor can include a doped region doped with N-type dopant. The second region AL can be an undoped region or a region doped at a lower concentration than the first regions SC, DR, and SCL.

[0124] The conductivity of the first regions SC, DR, and SCL can be greater than that of the second region AL, and the first regions SC, DR, and SCL can be used, or substantially used, as electrodes or signal lines. The second region AL can correspond to, or substantially correspond to, the active region AL (e.g., the channel) of transistor 100PC. In other words, a portion of AL in the semiconductor pattern SC, AL, DR, and SCL can be the active region AL of transistor 100PC, other portions of SC and DR can be the source region SC or drain region DR of transistor 100PC, and another portion of SCL can be a connecting electrode or a connecting signal line SCL.

[0125] Each pixel may have an equivalent circuit comprising multiple transistors, at least one capacitor, and at least one light-emitting element. The equivalent circuit of a pixel may be modified in various suitable forms as will be understood by those skilled in the art. Figure 6A An example is shown including a transistor 100PC and a light-emitting element 100PE in a pixel.

[0126] The source region SC, active region AL, and drain region DR of transistor 100PC can be formed by semiconductor patterns SC, AL, DR, and SCL. The source region SC and drain region DR can extend from the active region AL in opposite directions in cross-section (e.g., in a sectional view). Figure 6A A portion of the connection signal line SCL, formed by semiconductor patterns SC, AL, DR, and SCL, is shown. In another view, the connection signal line SCL may be connected in a plane (e.g., in a planar view) to the drain region DR of transistor 100PC.

[0129] The second insulating layer 20 may be disposed on the first insulating layer 10 and cover the gate GT. The second insulating layer 20 may overlap with the pixel. The second insulating layer 20 may be an inorganic layer and / or an organic layer, and may have a single-layer structure or a multilayer structure. The second insulating layer 20 may include at least one of silicon oxide, silicon nitride, and silicon oxide nitride. In an embodiment, the second insulating layer 20 may have a multilayer structure including a silicon oxide layer and a silicon nitride layer.

[0130] The third insulating layer 30 may be disposed on the second insulating layer 20. The third insulating layer 30 may have a single-layer structure or a multi-layer structure. For example, the third insulating layer 30 may have a multi-layer structure including a silicon oxide layer and a silicon nitride layer.

[0131] The first connection electrode CNE1 can be disposed on the third insulating layer 30. The first connection electrode CNE1 can be connected to the connection signal line SCL through a contact hole CNT-1 that passes through (e.g., penetrates) the first insulating layer 10, the second insulating layer 20 and the third insulating layer 30.

For example, the light-emitting element layer 130 may include organic light-emitting materials, inorganic light-emitting materials, organic-inorganic light-emitting materials, quantum dots, quantum rods, microLEDs, or nanoLEDs. In the following description, the light-emitting element 100PE may be described in more detail in the context of organic light-emitting elements, but this disclosure is not particularly limited thereto.

[0136] The light-emitting element 100PE may include a first electrode AE, a light-emitting layer EL, and a second electrode CE.

[0137] The first electrode AE ​​can be disposed on the sixth insulating layer 60. The first electrode AE ​​can be connected to the second connecting electrode CNE2 through a contact hole CNT-3 passing through (e.g., penetrating) the sixth insulating layer 60.

[0138] A pixel defining film 70 may be disposed on a sixth insulating layer 60 and cover a portion of the first electrode AE. An opening 70-OP may be defined in the pixel defining film 70. The opening 70-OP of the pixel defining film 70 exposes at least a portion of the first electrode AE.

[0139] First display unit DA1-F (for example, see...) Figure 1A The electrode may include a light-emitting region PXA and a non-light-emitting region NPXA adjacent to the light-emitting region PXA. The non-light-emitting region NPXA may surround the light-emitting region PXA (e.g., around the periphery of the light-emitting region PXA). In an embodiment, the light-emitting region PXA is defined to correspond to a portion of the first electrode AE ​​exposed by the opening 70-OP.

[0140] The light-emitting layer EL can be disposed on the first electrode AE. The light-emitting layer EL can be disposed in the region corresponding to the opening 70-OP. Figure 6A An illuminating layer EL is shown disposed within the opening 70-OP, but the present disclosure is not limited thereto. For example, the illuminating layer EL may extend to a portion covering the side surface of the pixel defining film 70 defining the opening 70-OP and the upper surface of the pixel defining film 70.

[0141] In embodiments of this disclosure, an emissive layer EL can be formed individually for each pixel. When an emissive layer EL is formed individually for each pixel, each emissive layer EL can emit light having at least one color selected from blue, red, and green. However, this disclosure is not limited thereto, and the emissive layers EL can be connected to the pixels and can be collectively included in the pixels. In this case, the emissive layers EL can provide blue light or white light.

[0142] The second electrode CE can be disposed on the light-emitting layer EL. The second electrode CE can have a monolithic shape and can be included together in multiple pixels.

[0143] In embodiments of this disclosure, a hole control layer may be disposed between the first electrode AE ​​and the light-emitting layer EL. The hole control layer may be jointly disposed within the light-emitting region PXA and the non-light-emitting region NPXA. The hole control layer may include a hole transport layer and may optionally include a hole injection layer. An electron control layer may be disposed between the light-emitting layer EL and the second electrode CE. The electron control layer may include an electron transport layer and may optionally include an electron injection layer. The hole control layer and the electron control layer may be jointly formed in multiple pixels using an aperture mask or an inkjet process.

[0144] An encapsulation layer 140 may be disposed on the light-emitting element layer 130. The encapsulation layer 140 may include sequentially stacked inorganic layers, organic layers, and inorganic layers, but the layers constituting the encapsulation layer 140 are not limited to these.

The inorganic layer may include a silicon nitride layer, a silicon oxide nitride layer, a silicon oxide layer, a titanium oxide layer, an aluminum oxide layer, etc. The organic layer may include an acryloyl-based organic layer, but this disclosure is not limited thereto.

[0145] The sensor layer 200 may include a base layer 201, a first conductive layer 202, an intermediate insulating layer 203, a second conductive layer 204, and a cover insulating layer 205.

[0146] The base layer 201 may be an inorganic layer comprising at least one of silicon nitride, silicon oxide nitride, and silicon oxide. As another example, the base layer 201 may be an organic layer comprising epoxy resin, acrylic resin, or an imide-based resin. The base layer 201 may have a monolayer structure or a multilayer structure in which multiple layers are stacked on a third-direction DR3. In embodiments of this disclosure, the sensor layer 200 may not include the base layer 201.

[0147] Each of the first conductive layer 202 and the second conductive layer 204 may have a single-layer structure or a multi-layer structure in which multiple layers are stacked on a third-direction DR3.

[0148] Each of the first conductive layer 202 and the second conductive layer 204, having a single-layer structure, may include a metal layer or a transparent conductive layer. The metal layer may include molybdenum, silver, titanium, copper, aluminum, or suitable alloys thereof. The transparent conductive layer may include a transparent conductive oxide such as indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), or indium zinc tin oxide (IZTO). Furthermore, the transparent conductive layer may include conductive polymers such as poly(3,4-ethylenedioxythiophene) (PEDOT), metal nanowires, graphene, etc.

[0149] Each of the first conductive layer 202 and the second conductive layer 204, which have a multilayer structure, may include multiple metal layers. The metal layers may have, for example, a three-layer structure of titanium / aluminum / titanium. A conductive layer with a multilayer structure may include at least one metal layer and at least one transparent conductive layer.

[0150] In embodiments of this disclosure, the thickness of the first conductive layer 202 can be greater than or equal to the thickness of the second conductive layer 204. When the thickness of the first conductive layer 202 is greater than the thickness of the second conductive layer 204, the resistance of components (e.g., electrodes, sensing patterns, bridging patterns, etc.) can be reduced. Furthermore, since the first conductive layer 202 can be disposed below the second conductive layer 204, even when the thickness of the first conductive layer 202 increases, the probability that components included in the first conductive layer 202 are visible due to reflection of external light is less than the probability that components included in the second conductive layer 204 are visible due to reflection of external light.

[0151] At least one of the intermediate insulating layer 203 and the cover insulating layer 205 may include an inorganic film. The inorganic film may include at least one of aluminum oxide, titanium oxide, silicon oxide, silicon nitride, silicon nitride, zirconium oxide, and hafnium oxide.

[0153] The sensor layer 200, comprising a first conductive layer 202 and a second conductive layer 204 (or in other words, two conductive layers in total), has been described above, but this disclosure is not particularly limited thereto. For example, the sensor layer 200 may include three or more conductive layers.

When the user USR views the first grid line MS1 and the second grid line MS2, the first grid line MS1 has a smaller width than the second grid line MS2, and therefore, the probability of the first grid line MS1 being visually recognized by the user USR can be reduced.

[0156] Each of the first grid line MS1 and the second grid line MS2 may include a first metal layer M1 and a second metal layer M2 disposed between the first metal layers M1. Exemplarily, the first metal layer M1 may include titanium (Ti), and the second metal layer M2 may include aluminum (Al). However, this disclosure is not particularly limited thereto.

[0157] In embodiments of this disclosure, the first thickness TK1 of the second metal layer M2 of the first grid line MS1 may be the same as or substantially the same as the second thickness TK2 of the second metal layer M2 of the second grid line MS2, but this disclosure is not particularly limited thereto. For example, the first thickness TK1 may be greater than the second thickness TK2. As another example, the second thickness TK2 may be greater than the first thickness TK1. In embodiments of this disclosure, each of the first thickness TK1 and the second thickness TK2 may be... Or larger, for example, such as

Each of the second electrode groups 220G may extend in the first direction DR1, and the second electrode groups 220G may be spaced apart from each other along the second direction DR2. The sensing unit (e.g., sensing region) SU of the sensor layer 200 may be a region in which one of the first electrode groups 210G and the second electrode group 220G intersect or cross each other.

[0162] Figure 7 Ten first electrode groups 210G and five second electrode groups 220G are shown as an example, and thus 50 sensing units SU are shown as an example, but the number of first electrode groups 210G and the number of second electrode groups 220G are not limited thereto.

The length of the (1-2) separating electrode D12 may be the same as or substantially the same as the length of the (2-2) separating electrode D22.

The length of the (1-4) separating electrode D14 may be the same as or substantially the same as the length of the (2-4) separating electrode D24. The length of the (1-5) separating electrode D15 may be the same as or substantially the same as the length of the (2-5) separating electrode D25.

[0167] According to embodiments of this disclosure, all of the first separating electrodes D1 in the plurality of second electrode groups 220G may have the same or substantially the same length d1 in the extending direction. All of the second separating electrodes D2 in the plurality of second electrode groups 220G may have the same or substantially the same length d2 in the extending direction. For example, the lengths of the (1-1) separating electrode D11, the (1-2) separating electrode D12, the (1-3) separating electrode D13, the (1-4) separating electrode D14 and the (1-5) separating electrode D15 may be the same or substantially the same, and the lengths of the (2-1) separating electrode D21, the (2-2) separating electrode D22, the (2-3) separating electrode D23, the (2-4) separating electrode D24 and the (2-5) separating electrode D25 may be the same or substantially the same.

[0168] refer to Figure 7 The third electrode groups 230G may be spaced apart from each other along the first direction DR1. In embodiments of this disclosure, each of the third electrode groups 230G may include a plurality of first auxiliary electrodes 230S electrically connected to each other. The number of first auxiliary electrodes 230S included in each (e.g., one) of the third electrode groups 230G may be modified differently as needed or desired. For example, as the number of first auxiliary electrodes 230S included in each of the third electrode groups 230G increases, the resistance of each of the third electrode groups 230G may decrease, and therefore, power efficiency may be improved and sensing sensitivity may be improved. On the other hand, as the number of first auxiliary electrodes 230S included in each of the third electrode groups 230G decreases, the loop coil pattern formed using the third electrode groups 230G may be implemented in a wider variety of suitable forms.

[0169] Figure 7 An exemplary illustration shows a third electrode group 230G including two first auxiliary electrodes 230S, but this disclosure is not particularly limited thereto. The first auxiliary electrodes 230S may be arranged in a one-to-one correspondence with the first electrode group 210G. Therefore, a sensing unit SU may include a portion of a first auxiliary electrode 230S.

[0170] A coupling capacitor can be defined between a first electrode group 210G and a first auxiliary electrode 230S. In this case, the induced current generated during pen sensing can be transmitted from the first auxiliary electrode 230S to the first electrode group 210G through the coupling capacitor. In other words, the first auxiliary electrode 230S can be used to supplement the signal transmitted from the first electrode group 210G to the sensor driving unit 200C. Therefore, the maximum effect can be obtained when the phase of the signal sensed in the first auxiliary electrode 230S and the phase of the signal sensed in the first electrode group 210G are consistent with each other. Therefore, the center of each of the first electrode group 210G in the second direction DR2 and the corresponding center of each of the first auxiliary electrodes 230S in the second direction DR2 can overlap with each other. Furthermore, the center of each of the first electrode group 210G in the first direction DR1 and the corresponding center of each of the first auxiliary electrodes 230S in the first direction DR1 can also overlap with each other.

[0171] In embodiments of this disclosure, because a third electrode group 230G includes two first auxiliary electrodes 230S, one third electrode group 230G can correspond to two first electrode groups 210G (e.g., can overlap with two first electrode groups 210G). Therefore, the number of first electrode groups 210G included in the sensor layer 200 can be greater than the number of third electrode groups 230G. For example, the number of first electrode groups 210G can be the same as the product of the number of third electrode groups 230G included in the sensor layer 200 and the number of first auxiliary electrodes 230S included in each of the third electrode groups 230G. Figure 7 In this embodiment, the number of first electrode groups 210G can be ten, the number of third electrode groups 230G can be five, and the number of first auxiliary electrodes 230S included in each of the third electrode groups 230G can be two. However, this disclosure is not limited thereto. As used herein, the phrase "A and B overlap each other" can mean that a part of "A" and a part of "B" overlap each other, the whole of "A" and a part of "B" overlap each other, the whole of "B" and a part of "A" overlap each other, or the whole of "A" and the whole of "B" overlap each other.

[0172] The fourth electrode group 240G may be spaced apart from each other along the second direction DR2. The fourth electrode group 240G may include a plurality of second auxiliary electrodes 240S. In embodiments of this disclosure, each of the fourth electrode groups 240G may include two second auxiliary electrodes 240S, but this disclosure is not particularly limited thereto. The second auxiliary electrodes 240S may be arranged in a one-to-one correspondence with the fourth electrode group 240G. The fourth electrode group 240G may include a plurality of second auxiliary electrodes 240S arranged along the second direction DR2. Each of the second auxiliary electrodes 240S may extend in the first direction DR1. In embodiments of this disclosure, the second auxiliary electrodes 240S may be electrically connected to each other.

[0173] At least a portion of a second auxiliary electrode 240S may overlap with each of the first separator electrode D1 and the second separator electrode D2 constituting a second electrode group 220G. A second auxiliary electrode 240S may extend continuously in a first direction DR1 from one end of the first separator electrode D1 adjacent to the peripheral region 200NA to one end of the second separator electrode D2 adjacent to the peripheral region 200NA.

[0174] A coupling capacitor can be defined between a second electrode group 220G and a second auxiliary electrode 240S. In this case, the induced current generated during pen sensing can be transmitted from the second auxiliary electrode 240S to the second electrode group 220G through the coupling capacitor. In other words, the second auxiliary electrode 240S can be used to supplement the signal transmitted from the second electrode group 220G to the sensor driving unit 200C. Therefore, the maximum effect can be obtained when the phase of the signal sensed in the second auxiliary electrode 240S and the phase of the signal sensed in the second electrode group 220G are consistent with each other. Therefore, the center of each of the second electrode group 220G in the first direction DR1 and the corresponding center of each of the second auxiliary electrodes 240S in the first direction DR1 can overlap with each other. Furthermore, the center of each of the second electrode group 220G in the second direction DR2 and the corresponding center of each of the second auxiliary electrodes 240S in the second direction DR2 can also overlap with each other.

[0175] like Figure 8AAs shown, in this embodiment, the fourth electrode group 240G may include a (2-1) auxiliary electrode 240S1, a (2-2) auxiliary electrode 240S2, a (2-3) auxiliary electrode 240S3, a (2-4) auxiliary electrode 240S4, and a (2-5) auxiliary electrode 240S5 arranged sequentially along the second direction DR2. The (2-1) auxiliary electrode 240S1 may overlap with the (2-1) electrode group 220G1. The (2-2) auxiliary electrode 240S2 may overlap with the (2-2) electrode group 220G2. The (2-3) auxiliary electrode 240S3 may overlap with the (2-3) electrode group 220G3. The (2-4) auxiliary electrode 240S4 may overlap with the (2-4) electrode group 220G4. The (2-5) auxiliary electrode 240S5 may overlap with the (2-5) electrode group 220G5.

[0176] refer to Figure 7 The sensor layer 200 may further include a plurality of first traces 210t arranged in the peripheral region 200NA and a plurality of first pads PD1 connected to the first traces 210t in a one-to-one correspondence. The first traces 210t may be electrically connected to the first electrode group 210G in a one-to-one correspondence. In other words, one first trace 210t may be connected to one first electrode group 210G.

[0177] The sensor layer 200 may further include a plurality of second traces 220t and a plurality of second pads PD2 connected to the second traces 220t in a one-to-one correspondence. In embodiments of this disclosure, the second traces 220t may be associated with a non-display area 100NA (e.g., see...). Figure 4 The second trace 220t can be electrically connected to the second electrode group 220G in a two-to-one correspondence. Therefore, the number of second traces 220t can be twice the number of second electrode groups 220G. In other words, two second traces 220t can be connected to one second electrode group 220G.

[0178] The second trace 220t may include a first separating trace 220t1 and a second separating trace 220t2. The first separating trace 220t1 may be electrically connected to the first separating electrode D1 in a one-to-one correspondence. The second separating trace 220t2 may be electrically connected to the second separating electrode D2 in a one-to-one correspondence. In an embodiment, each of the first separating traces 220t1 may be connected to the end of the corresponding first separating electrode D1 adjacent to the peripheral region 200NA, and each of the second separating traces 220t2 may be connected to the end of the corresponding second separating electrode D2 adjacent to the peripheral region 200NA. The first separating traces 220t1 and the second separating trace 220t2 may be spaced apart from each other, with the first separating electrode D1 and the second separating electrode D2 interposed between them.

[0179] like Figure 8A As shown, in an embodiment, the first separating trace 220t1 may include the (1-1) separating trace 11 electrically connected to the (1-1) separating electrode D11, the (1-2) separating trace 12 electrically connected to the (1-2) separating electrode D12, the (1-3) separating trace 13 electrically connected to the (1-3) separating electrode D13, the (1-4) separating trace 14 electrically connected to the (1-4) separating electrode D14, and the (1-5) separating trace 15 electrically connected to the (1-5) separating electrode D15. The second separation trace 220t2 may include the (2-1) separation trace 21 electrically connected to the (2-1) separation electrode D21, the (2-2) separation trace 22 electrically connected to the (2-2) separation electrode D22, the (2-3) separation trace 23 electrically connected to the (2-3) separation electrode D23, the (2-4) separation trace 24 electrically connected to the (2-4) separation electrode D24, and the (2-5) separation trace 25 electrically connected to the (2-5) separation electrode D25.

[0180] refer to Figure 7 The sensor layer 200 may also include a third trace 230rt1 arranged in the peripheral area 200NA, a third pad PD3 connected to the third trace 230rt1 in a one-to-one correspondence, a fourth trace 230rt2, and a fourth pad PD4 connected to one end and the other end (e.g., opposite ends) of the fourth trace 230rt2.

[0181] The third trace 230rt1 can be connected to the third electrode group 230G in a one-to-one correspondence. In other words, the number of third traces 230rt1 can correspond to the number of third electrode groups 230G. Figure 7 Five third traces 230rt1 are shown as an example.

[0182] In embodiments of this disclosure, the third trace 230rt1 and the third pad PD3 may be omitted as needed or desired, and the charging drive mode for charging the pen may be omitted as needed or desired. In this case, the sensor layer 200 can sense input from an active pen that emits a magnetic field even when no magnetic field is provided from the sensor layer 200.

[0183] The fourth trace 230rt2 may be electrically connected to at least one of the first auxiliary electrodes 230S. In embodiments of this disclosure, the fourth trace 230rt2 may be electrically connected to all of the first auxiliary electrodes 230S. In other words, the fourth trace 230rt2 may be electrically connected to all of the third electrode group 230G. The fourth trace 230rt2 may include a first wire portion 231t extending in a first direction DR1 and electrically connected to the third electrode group 230G, a second wire portion 232t extending in a second direction DR2 from a first end of the first wire portion 231t, and a third wire portion 233t extending in a second direction DR2 from a second end of the first wire portion 231t.

[0184] In embodiments of this disclosure, each of the resistances of the second wire portion 232t and the third wire portion 233t can be the same as or substantially the same as the resistance of one of the third electrode groups 230G. Therefore, the second wire portion 232t and the third wire portion 233t can be used as the third electrode group 230G, and the same or substantially the same effect as if the third electrode group 230G were also arranged in the peripheral region 200NA can be obtained. For example, any one of the second wire portion 232t and the third wire portion 233t, and any one of the third electrode groups 230G, can form a coil. Therefore, a pen positioned in a region adjacent to the peripheral region 200NA can also be adequately charged through a loop including the second wire portion 232t or the third wire portion 233t.

[0185] In embodiments of this disclosure, the width of each of the second line portion 232t and the third line portion 233t in the first direction DR1 can be adjusted differently as needed or desired to adjust the resistance of the second line portion 232t and the third line portion 233t. However, this disclosure is not limited thereto, 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.

[0186] The sensor layer 200 may also include a fifth trace 240t, at least a portion of which is configured to overlap with the sensing area 200A. At least a portion of the fifth trace 240t may overlap with the display area 100A (e.g., see [link to display area]). Figure 4Overlap. For example, when viewed on a plane (e.g., in a plan view), display area 100A (e.g., see...) Figure 4 The shape or area of ​​the fifth trace 240t can be the same as or substantially the same as (or similar to) the shape or area of ​​the sensing area 200A. The fifth trace 240t can be electrically connected to the fourth electrode group 240G. The fifth trace 240t can be electrically connected to all of the second auxiliary electrodes 240S.

[0187] like Figure 7 and Figure 8A As shown, at least a portion of the fifth trace 240t may extend within the gap GP between the first separator electrode D1 and the second separator electrode D2. At least a portion of the fifth trace 240t may connect adjacent fourth electrode groups 240G (e.g., adjacent second auxiliary electrodes 240S) to each other within the sensing region 200A. In an embodiment, the fifth trace 240t may include a (5-1) trace 240t1 and a (5-2) trace 240t2.

[0188] Each of the (5-1) traces 240t1 can be a line connecting adjacent second auxiliary electrodes 240S to each other. For example, each of the (5-1) traces 240t1 can extend in the second direction DR2 from one side of any second auxiliary electrode 240S to one side of another adjacent second auxiliary electrode 240S. One side of any second auxiliary electrode 240S and one side of the other second auxiliary electrode 240S can correspond to side surfaces facing each other in the second direction DR2. Each side of any second auxiliary electrode 240S and one side of the other second auxiliary electrode 240S can correspond in a plane (e.g., in a plan view) to a long side extending in the first direction DR1. The (5-1) trace 240t1 can extend from the portion of the second electrode group 220G exposed from one side of the corresponding second auxiliary electrode 240S through the gap GP between the first separator D1 and the second separator D2. In other words, the (5-1)trace 240t1 can extend from the portion of the corresponding second auxiliary electrode 240S that does not overlap with the second electrode group 220G (e.g., the first separator electrode D1 and the second separator electrode D2).

[0189] The (5-2) trace 240t2 can be a line connecting the fourth electrode group 240G and the fifth pad PD5 to each other. In other words, the (5-2) trace 240t2 can electrically connect the fourth electrode group 240G and the sensor driving unit 200C to each other. The (5-2) trace 240t2 can connect the fifth pad PD5 and the second auxiliary electrode 240S closest to the fifth pad PD5 among the second auxiliary electrodes 240S to each other. For example, the (5-2) trace 240t2 can extend from one side of the second auxiliary electrode 240S closest to the fifth pad PD5 among the second auxiliary electrodes 240S to the fifth pad PD5.

[0190] like Figure 8A As shown, in an embodiment, the (5-1) trace 240t1 may include a first connecting trace S11 that connects the (2-1) auxiliary electrode 240S1 and the (2-2) auxiliary electrode 240S2 to each other, a second connecting trace S12 that connects the (2-2) auxiliary electrode 240S2 and the (2-3) auxiliary electrode 240S3 to each other, a third connecting trace S13 that connects the (2-3) auxiliary electrode 240S3 and the (2-4) auxiliary electrode 240S4 to each other, and a fourth connecting trace S14 that connects the (2-4) auxiliary electrode 240S4 and the (2-5) auxiliary electrode 240S5 to each other.

[0191] like Figure 8B As shown, the fourth electrode group 240G and the fifth trace 240t can be arranged in the same layer as each other (e.g., in the same layer or on the same layer). In an embodiment, the second auxiliary electrode 240S and the (5-1) trace 240t1 and the (5-2) trace 240t2 can be formed together in an integral shape.

[0192] According to the embodiment, in the sensor layer 200, a separation structure can be applied to the second electrode group 220G extending in the long axis direction, and thus, the resistance of the separation electrode included in the sensing unit SU of the second electrode group 220G can be reduced. Therefore, the frequency range (e.g., bandwidth) of the signal that can be applied to the sensor layer 200 can be more ensured, and the degree of freedom in selecting the frequency can be improved.

[0193] According to an embodiment, a separation structure can be applied to the second electrode group 220G, and therefore, the fifth trace 240t can be disposed through the gap GP inside the second electrode group 220G. Thus, at least a portion of the fifth trace 240t can be connected to the sensing area 200A or the display area 100A (e.g., see...). Figure 4 This overlaps. Therefore, the area of ​​the surrounding region 200NA can be reduced. As a result, the size of the electronic device 1000 can be reduced (see, for example, see...). Figure 1AThe front surface of the device is occupied by a 200NA area around the perimeter, and a narrower bezel can be achieved.

[0194] As used in this paper, multiple second traces 220t can be referred to as multiple first lines, multiple fifth traces 240t can be referred to as multiple second lines, multiple first traces 210t can be referred to as multiple third lines, and multiple third traces 230rt1 can be referred to as multiple fourth lines. Multiple first dividing traces 220t1 can be referred to as multiple (1-1) lines, and multiple second dividing traces 220t2 can be referred to as multiple (1-2) lines. The (5-1)th trace 240t1 can be referred to as the (2-1)th line, and the (5-2)th trace 240t2 can be referred to as the (2-2)th line.

Figure 10A This is a plan view showing the first conductive layer 202SU of a sensor unit according to an embodiment of the present disclosure. Figure 10B This is a plan view showing the second conductive layer 204SU of a sensor unit according to an embodiment of the present disclosure. Figure 10C It is according to the embodiments of this disclosure along Figure 10A and Figure 10B The cross-sectional view of sensor layer 200 taken by line I-I' shown is shown.

[0196] refer to Figure 7 , Figure 9 and Figures 10A to 10C Each of the first electrode groups 210G may include first unit separator electrodes 210dv1 and 210dv2. The first unit separator electrodes 210dv1 and 210dv2 may extend in a second direction DR2 and may be spaced apart from each other in a first direction DR1. The first unit separator electrodes 210dv1 and 210dv2 may have a shape that is linearly symmetrical to each other with respect to the lines extending in the second direction DR2.

[0197] Two first unit separator electrodes 210dv1 and 210dv2, included in a first electrode group 210G, can be connected to one of the first traces 210t. Each of the first traces 210t may include multiple branches for connecting to the two first unit separator electrodes 210dv1 and 210dv2. In embodiments of this disclosure, the two first unit separator electrodes 210dv1 and 210dv2 can be connected to each other within a sensing region 200A.

[0198] Each of the second electrode groups 220G may include a first separator electrode D1 and a second separator electrode D2. Each of the first separator electrode D1 and the second separator electrode D2 may include second unit separator electrodes 220dv1 and 220dv2. Figures 9 to 10B An exemplary illustration is shown of a first separator electrode 220-D1, which is one of a first separator electrode D1 and a second separator electrode D2. Second unit separator electrodes 220dv1 and 220dv2 may extend in a first direction DR1 and may be spaced apart from each other in a second direction DR2. The second unit separator electrodes 220dv1 and 220dv2 may have a shape that is linearly symmetrical to each other with respect to the lines extending in the first direction DR1.

[0199] Each of the second unit separator electrodes 220dv1 and 220dv2 may include a sensing pattern 221 and a bridging pattern 222. The sensing pattern 221 and the bridging pattern 222 may be disposed in different layers (e.g., in different layers or on different layers). The sensing pattern 221 and the bridging pattern 222 may be electrically connected to each other via a first contact CNa. For example, the bridging pattern 222 may be included in a first conductive layer 202SU, and the sensing pattern 221 and the first unit separator electrodes 210dv1 and 210dv2 may be included in a second conductive layer 204SU. The first conductive layer 202SU may be included in the above reference. Figure 6A The first conductive layer 202 is described, and the second conductive layer 204SU may be included in the above reference. Figure 6A In the second conductive layer 204 described.

[0200] Each of the first auxiliary electrodes 230S included in the third electrode group 230G may include a (3-1) pattern 231 and a (3-2) pattern 232. The (3-1) pattern 231 and the (3-2) pattern 232 may be arranged in different layers (e.g., in different layers or on different layers). The (3-1) pattern 231 and the (3-2) pattern 232 may be electrically connected to each other via a second contact CNb. The (3-1) pattern 231 may be included in the first conductive layer 202SU, and the (3-2) pattern 232 may be included in the second conductive layer 204SU.

[0201] In embodiments of this disclosure, a portion of the (3-1) pattern 231 may overlap with a portion of each of the first unit separating electrodes 210dv1 and 210dv2. Therefore, a coupling capacitor may be provided (e.g., may be formed) between the first electrode group 210G and the third electrode group 230G.

[0202] Each of the second auxiliary electrodes 240S included in the fourth electrode group 240G may include a (4-1) pattern 241, a (4-2) pattern 242, and a (4-3) pattern 243. The (4-2) pattern 242 and the (4-3) pattern 243 may be arranged in the same layer as each other (e.g., in the same layer or on the same layer). The (4-1) pattern 241 may be disposed in a different layer than the (4-2) pattern 242 and the (4-3) pattern 243 (e.g., in a different layer or on a different layer). The (4-1) pattern 241 and the (4-2) pattern 242 may be electrically connected to each other via a third contact CNc. The (4-1) pattern 241 and the (4-3) pattern 243 may be electrically connected to each other via a fourth contact CNd. Patterns 242 (4-2) and 243 (4-3) may be included in the first conductive layer 202SU, and pattern 241 (4-1) may be included in the second conductive layer 204SU.

[0203] In embodiments of this disclosure, a portion of the (4-2) pattern 242 may overlap with the sensing pattern 221 of each of the second unit separating electrodes 220dv1 and 220dv2. Therefore, a coupling capacitor may be provided (e.g., may be formed) between the second electrode group 220G and the fourth electrode group 240G.

[0204] In embodiments of this disclosure, the first conductive layer 202SU may further include dummy patterns DMPs. Each of the dummy patterns DMPs may be electrically floated or electrically grounded. In embodiments of this disclosure, the dummy patterns DMPs may be omitted as needed or desired. The dummy patterns DMPs may be arranged in empty spaces, and therefore, the probability that a particular pattern may be visually identifiable by reflection of external light can be reduced. In other words, an electronic device 1000 may be provided with improved visibility due to reflection of external light (e.g., see...). Figure 1A ).

[0205] Figure 11A This is a plan view showing the first conductive layer 202SUa of a sensor unit according to an embodiment of the present disclosure. Figure 11B This is a plan view showing the second conductive layer 204SUa of a sensor unit according to an embodiment of the present disclosure. Figure 11C It is according to the embodiments of this disclosure along Figure 11A and Figure 11B The cross-sectional view of sensor layer 200 taken by line II-II' shown is shown.

[0206] refer to Figure 7 , Figure 11A , Figure 11B and Figure 11CEach of the first electrode groups 210G may include a plurality of first sensing patterns 211 and a plurality of first bridging patterns 212. The first sensing patterns 211 may be spaced apart from each other in the second direction DR2. The first bridging patterns 212 may extend in the second direction DR2 and may be electrically connected to the first sensing patterns 211 through a first contact CNa1. Figure 11A and Figure 11B Exemplary illustration shows two adjacent first sensing patterns 211 electrically connected to each other via two first bridging patterns 212, but this disclosure is not particularly limited thereto. For example, two adjacent first sensing patterns 211 may be electrically connected to each other via one first bridging pattern 212, or via three or more first bridging patterns 212.

[0207] Figure 11B An exemplary illustration shows a first separator electrode 220-D1 from a first separator electrode D1 and a second separator electrode D2. First sensing patterns 211 adjacent to each other in the second direction DR2 may be spaced apart, with the first separator electrode 220-D1 interposed between them. In embodiments of this disclosure, the first sensing pattern 211, the first separator electrode 220-D1, and the second separator electrode D2 may be included in a second conductive layer 204SUa, and a first bridging pattern 212 may be included in a first conductive layer 202SUa. The first bridging pattern 212 may be insulated from and cross or intersect with the first separator electrode D1 or the second separator electrode D2 that overlaps with the first bridging pattern 212.

[0208] Each of the first auxiliary electrodes 230S included in the third electrode group 230G may extend in the second direction DR2. The first auxiliary electrodes 230S may be included in the first conductive layer 202SUa. One or more holes may be defined in each of the first auxiliary electrodes 230S. A first bridging pattern 212 may be disposed in one of the holes. Therefore, the first bridging pattern 212 may be electrically insulated from the first auxiliary electrodes 230S.

[0209] Each of the second auxiliary electrodes 240S included in the fourth electrode group 240G may include a plurality of second sensing patterns 241a and a plurality of second bridging patterns 242a. The second sensing patterns 241a may be spaced apart from each other in the first direction DR1. The second bridging patterns 242a may extend in the first direction DR1 and may be electrically connected to the second sensing patterns 241a through the second contact portion CNb1.

[0210] Figure 11A and Figure 11BExemplary illustration shows two adjacent second sensing patterns 241a electrically connected to each other via two second bridging patterns 242a, but this disclosure is not particularly limited thereto. For example, two adjacent second sensing patterns 241a may be electrically connected to each other via one second bridging pattern 242a, or via three or more second bridging patterns 242a.

[0211] In embodiments of this disclosure, the second sensing pattern 241a and the first auxiliary electrode 230S may be included in the first conductive layer 202SUa, and the second bridging pattern 242a may be included in the second conductive layer 204SUa. The second bridging pattern 242a may be insulated from and intersect or cross the first auxiliary electrode 230S that overlaps with the second bridging pattern 242a.

[0212] refer to Figure 11A and Figure 11B In the second conductive layer 204SUa inside a sensing unit SU, the area occupied by components included in the first electrode group 210G and the second electrode group 220G can be larger than the area occupied by components included in the third electrode group 230G and the fourth electrode group 240G. Because the first input 2000 (e.g., see...) Figure 4 The change in capacitance caused by this can vary with a distance of 2000 from the first input (e.g., see [reference]). Figure 4 The distance becomes shorter and larger. Therefore, the distance used to sense the first input 2000 (e.g., see...) Figure 4 The components can be used with electronic device 1000 (e.g., see...). Figure 1A The layers adjacent to the surface are arranged in a relatively larger area. As a result, touch performance can be improved.

[0213] In embodiments of this disclosure, the first conductive layer 202SUa may further include a first dummy pattern DMP1, and the second conductive layer 204SUa may further include a second dummy pattern DMP2. Each of the first dummy pattern DMP1 and the second dummy pattern DMP2 may be floating or electrically floating. Each of the first dummy pattern DMP1 and the second dummy pattern DMP2 may be divided into multiple conductive patterns. For example, a first dummy pattern DMP1 may include multiple floating dummy patterns spaced apart from each other (e.g., separated or electrically separated).

[0214] refer to Figure 11CThe regions of the first auxiliary electrode 230S and the first sensing pattern 211 can be adjusted differently as needed or desired. For example, the positions of the boundaries between the first auxiliary electrode 230S and the first dummy pattern DMP1, and the boundaries between the first sensing pattern 211 and the second dummy pattern DMP2, can be adjusted differently as needed or desired. In this case, the area of ​​the overlapping region where the first auxiliary electrode 230S and the first sensing pattern 211 overlap can be adjusted as needed or desired, and therefore, the capacitance of the coupling capacitor C-CP between the first auxiliary electrode 230S and the first sensing pattern 211 can be adjusted as needed or desired.

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 suitable direction (e.g., a predetermined direction) and may be interconnected. The shape may include a variety of suitable shapes, such as straight lines, lines with protrusions, and non-straight lines. Openings in which the grid structure is not arranged may be defined (e.g., may be provided or formed) in each of the first electrode group 210G, the second electrode group 220G, the third electrode group 230G, the fourth electrode group 240G, and the dummy pattern DMP.

However, this disclosure is not limited thereto, and the extension directions of the mesh lines constituting the mesh structure are not particularly limited to... Figure 12A and Figure 12BThe directions shown are as follows. For example, the mesh structure may include mesh lines extending in the first direction DR1 and the second direction DR2 (e.g., it may only include mesh lines extending in the first direction DR1 and the second direction DR2), or it may include mesh lines extending in the first direction DR1, the second direction DR2, the first intersecting direction CDR1, and the second intersecting direction CDR2. In other words, the mesh structure can be modified into various suitable forms as needed or desired.

Figure 14 The diagram schematically illustrates electrodes from a first electrode group 210G, a second electrode group 220G, a third electrode group 230G, and a fourth electrode group 240G (see, for example, see...). Figure 7 The second electrode group 220G and the fourth electrode group 240G are in the ).

[0221] refer to Figure 7 and Figure 14 Each of the second electrode groups 220G may include a first separating electrode D1 and a second separating electrode D2. According to embodiments of this disclosure, at least some of the first separating electrodes D1 of the second electrode group 220G may have different lengths from each other (e.g., lengths in the extending direction, the major axis direction, or the first direction DR1). At least some of the second separating electrodes D2 of the second electrode group 220G may have different lengths from each other (e.g., lengths in the extending direction, the major axis direction, or the first direction DR1).

[0222] For example, the lengths of the (1-1) separating electrode D11, the (1-2) separating electrode D12, the (1-3) separating electrode D13, the (1-4) separating electrode D14 and the (1-5) separating electrode D15 can be different from each other, and the lengths of the (2-1) separating electrode D21, the (2-2) separating electrode D22, the (2-3) separating electrode D23, the (2-4) separating electrode D24 and the (2-5) separating electrode D25 can be different from each other. For example, the (1-1) separating electrode D11, the (1-2) separating electrode D12, the (1-3) separating electrode D13, the (1-4) separating electrode D14, and the (1-5) separating electrode D15 may have successively increasing lengths, and the (2-1) separating electrode D21, the (2-2) separating electrode D22, the (2-3) separating electrode D23, the (2-4) separating electrode D24, and the (2-5) separating electrode D25 may have successively decreasing lengths. Within the second electrode group 220G, the gap GP' defined between the adjacent first separating electrode D1 and second separating electrode D2 may be arranged along an oblique direction of the first direction DR1 and the second direction DR2 (e.g., between the first direction DR1 and the second direction DR2).

[0223] The fifth trace 240t may include the (5-1) trace 240t1 and the (5-2) trace 240t2. In embodiments of this disclosure, at least some of the (5-1) traces 240t1 may extend within the gap GP' between adjacent first separator electrodes D1 and second separator electrodes D2. In embodiments, the gap GP' within the second electrode group 220G is arranged along a diagonal direction, and therefore, each of the (5-1) traces 240t1 may include a curved portion. However, this disclosure is not limited to... Figure 14 The (5-1) trace 240t1 shown, and the shape and / or extension direction of the (5-1) trace 240t1 can be modified differently as needed or desired.

[0224] Figure 15 This is a view showing some electrode groups inside the sensor layer 200 according to an embodiment of the present disclosure. Figure 15 The diagram schematically illustrates electrodes from a first electrode group 210G, a second electrode group 220G, a third electrode group 230G, and a fourth electrode group 240G (see, for example, see...). Figure 7 The second electrode group 220G and the fourth electrode group 240G are in the ).

[0225] refer to Figure 7 and Figure 15 In embodiments of this disclosure, at least some of the second traces 220t may be associated with display area 100A (e.g., see [reference]). Figure 4The second trace 220t may extend to overlap with the second electrode group 220G, or extend to be insulated from and intersect or cross the second electrode group 220G.

[0226] The second trace 220t can be electrically connected to the second electrode group 220G in a two-to-one correspondence. The second trace 220t may include a first separating trace 220t1 electrically connected to the first separating electrode D1 in a one-to-one correspondence and a second separating trace 220t2 electrically connected to the second separating electrode D2 in a one-to-one correspondence. At least some of the first separating traces 220t1 may overlap with at least some of the first separating electrodes D1, or may be insulated from and cross or intersect with at least some of the first separating electrodes D1. At least some of the second separating traces 220t2 may overlap with at least some of the second separating electrodes D2, or may be insulated from and cross or intersect with at least some of the second separating electrodes D2.

[0227] Figure 15 Exemplarily shown is each of the first separating traces 220t1 connected to a corresponding first separating electrode D1 via a first contact CNT1, and each of the second separating traces 220t2 connected to a corresponding second separating electrode D2 via a second contact CNT2. However, this disclosure is not limited thereto, and each of the first separating traces 220t1 may be disposed in the same layer as the corresponding first separating electrode D1 (e.g., in the same layer or on the same layer) and have an integral shape, and each of the second separating traces 220t2 may be disposed in the same layer as the corresponding second separating electrode D2 (e.g., in the same layer or on the same layer) and have an integral shape.

The (2-1) separating trace 21, the (2-2) separating trace 22, the (2-3) separating trace 23, the (2-4) separating trace 24, and the (2-5) separating trace 25 can be arranged sequentially along the first direction DR1. Therefore, the first contact portion CNT1 can be arranged along the oblique direction of the first direction DR1 and the second direction DR2 (for example, referred to as the first oblique direction below), and the second contact portion CNT2 can be arranged along the second oblique direction that intersects or crosses the first oblique direction. However, the arrangement order of the first separating trace 220t1 and the second separating trace 220t2, or the arrangement form of the first contact portion CNT1 and the second contact portion CNT2, is not limited to this.

[0229] According to the embodiment, all the second traces 220t and the fifth traces 240t are arranged such that they at least partially overlap with the sensing region 200A, and therefore, the area of ​​the surrounding region 200NA can be reduced. As a result, the size of the electronic device 1000 can be reduced (e.g., see...). Figure 1A The front surface of the device is occupied by a 200NA area around the perimeter, and a narrower bezel can be achieved.

Each of the second auxiliary electrodes 240Sa may include an electrode divided into two parts.

The first auxiliary separator electrode SD1 and the second auxiliary separator electrode SD2 included in a fourth electrode group 240Ga may sense the same axis (e.g., an axis extending in the first direction DR1). The first auxiliary separator electrode SD1 may overlap with a corresponding first separator electrode D1 of the second electrode group 220G, and the second auxiliary separator electrode SD2 may overlap with a corresponding second separator electrode D2 of the second electrode group 220G.

[0233] Figure 16 Exemplarily shown is the length d1-1 of the first auxiliary separator electrode SD1 in the extending direction (e.g., the major axis direction, such as the first direction DR1) being the same or substantially the same as the length d2-1 of the second auxiliary separator electrode SD2 in the extending direction (e.g., the major axis direction). Furthermore, in Figure 16 In the fourth electrode group 240Ga, all the first auxiliary separator electrodes SD1 have the same length d1-1, and all the second auxiliary separator electrodes SD2 have the same length d2-1. However, this disclosure is not limited thereto.

[0256] Figure 19 This is a view showing the operation of the sensor driving unit 200C according to an embodiment of the present disclosure. Figure 20 This is a view showing the operation of the sensor driving unit 200C according to an embodiment of the present disclosure.

[0257] refer to Figure 5 and Figure 19 The sensor driving unit 200C can be selectively driven in one of the first operating mode DMD1, the second operating mode DMD2, and the third operating mode DMD3.

[0258] The first operation mode DMD1 can be referred to as the touch and pen wait mode. The second operation mode DMD2 can be referred to as the touch-activated and pen wait mode. The third operation mode DMD3 can be referred to as the pen-activated mode. The first operation mode DMD1 can be a mode that waits for the first input 2000 and the second input 3000. The second operation mode DMD2 can be a mode that senses the first input 2000 and waits for the second input 3000. The third operation mode DMD3 can be a mode that senses the second input 3000.

[0259] In embodiments of this disclosure, the sensor driving unit 200C may initially be driven in a first operating mode DMD1. When the first input 2000 is sensed in the first operating mode DMD1, the sensor driving unit 200C may switch (e.g., may change) to a second operating mode DMD2. As another example, when the second input 3000 is sensed in the first operating mode DMD1, the sensor driving unit 200C may switch (e.g., may change) to a third operating mode DMD3.

[0260] In embodiments of this disclosure, when the second input 3000 is sensed in the second operating mode DMD2, the sensor driving unit 200C can switch to the third operating mode DMD3. When the first input 2000 is released (e.g., not sensed) in the second operating mode DMD2, the sensor driving unit 200C can switch to the first operating mode DMD1. When the second input 3000 is released (e.g., not sensed) in the third operating mode DMD3, the sensor driving unit 200C can switch to the first operating mode DMD1.

[0261] Figure 20 Some operations are illustrated in the order of time “t” under the first operating mode DMD1, the second operating mode DMD2, and the third operating mode DMD3.

[0262] refer to Figure 5 , Figure 19 and Figure 20 In the first operating mode DMD1, the sensor driving unit 200C can be driven repeatedly in the second mode MD2-d and the first mode MD1-d. During the second mode MD2-d, the sensor layer 200 can scan to detect the second input 3000. During the first mode MD1-d, the sensor layer 200 can scan to detect the first input 2000. Figure 20 An example is shown where the sensor drive unit 200C operates in the first mode MD1-d consecutively after the second mode MD2-d, but the order is not limited to this.

[0263] In the second operating mode DMD2, the sensor driving unit 200C can be driven repeatedly in the second mode MD2-d and the first mode MD1. During the second mode MD2-d, the sensor layer 200 can scan to detect the second input 3000. During the first mode MD1, the sensor layer 200 can scan to detect the coordinates of the first input 2000.

[0264] In the third operating mode DMD3, the sensor driving unit 200C can be driven in the second mode MD2. During the second mode MD2, the sensor layer 200 can scan to detect the coordinates of the second input 3000. In the third operating mode DMD3, the sensor driving unit 200C may not operate in the first mode MD1-d or MD1 until the second input 3000 is released (e.g., the second input 3000 is not sensed).

[0265] Let's refer to it together. Figure 7In the first operating mode MD1-d of DMD1 and the first operating mode MD1 of DMD2, all of the third electrode group 230G and the fourth electrode group 240G can be grounded or have a constant voltage applied to them. As another example, in the first operating modes MD1-d and MD1, all of the third electrode group 230G and the fourth electrode group 240G can be floating. As another example, in the first operating modes MD1-d and MD1, a signal having the same phase as the transmission signal provided to the first electrode group 210G can be applied to the third electrode group 230G and the fourth electrode group 240G. In this case, the introduction of touch noise through the third electrode group 230G and the fourth electrode group 240G can be prevented or substantially prevented.

[0266] In the first operating mode DMD1 or the second operating mode DMD2-d, and in the second operating mode DMD3, the second operating mode MD2, one end of each of the third electrode group 230G and the fourth electrode group 240G can be floating. Furthermore, in the second operating mode MD2-d and the second operating mode MD2, the other end (e.g., the opposite end) of each of the third electrode group 230G and the fourth electrode group 240G can be grounded or floating. Therefore, through the coupling between the first electrode group 210G and the third electrode group 230G, and the coupling between the second electrode group 220G and the fourth electrode group 240G, compensation for the sensing signal can be maximized or increased.

[0267] Figure 21 This is a view illustrating a first mode according to an embodiment of the present disclosure.

[0268] refer to Figure 5 , Figure 20 and Figure 21 The first mode MD1-d of the first operating mode DMD1 and the first mode MD1 of the second operating mode DMD2 may include a mutual capacitance detection mode. Figure 21 The mutual capacitance detection modes under the first mode MD1-d of the first operating mode DMD1 and the first mode MD1 of the second operating mode DMD2 are shown.

[0269] In mutual capacitance detection mode, the sensor driving unit 200C can sequentially provide transmission signals TX to the first electrode group 210G, and can use the received signal RX detected by the second electrode group 220G to detect the coordinates of the first input 2000. For example, the sensor driving unit 200C can calculate the input coordinates by sensing the change in mutual capacitance between the first electrode group 210G and the second electrode group 220G.

[0270] Figure 21An exemplary illustration shows the provision of a transmission signal TX to a first electrode group 210G and the output of a receive signal RX from a second electrode group 220G. For clarity of signal representation, Figure 21 A first electrode group 210G, which is provided with a transmission signal TX, is shown in bold. The sensor driving unit 200C can detect the input coordinates of the first input 2000 by sensing the change in capacitance between the first electrode group 210G and the second electrode group 220G.

[0271] In embodiments of this disclosure, at least one of the first mode MD1-d of the first operating mode DMD1 and the first mode MD1 of the second operating mode DMD2 may further include a self-capacitance detection mode. In the self-capacitance detection mode, the sensor driving unit 200C can output driving signals to the first electrode group 210G and the second electrode group 220G, and can calculate the input coordinates by sensing the change in capacitance between the first electrode group 210G and the second electrode group 220G. The operations of outputting driving signals to the first electrode group 210G and the second electrode group 220G can be performed separately at different times, or they can overlap in time.

[0272] Figure 22 This is a view illustrating a second mode according to an embodiment of the present disclosure. Figure 23A It is a graph showing the waveform of the first signal according to an embodiment of the present disclosure. Figure 23B This is a graph showing the waveform of the second signal according to an embodiment of the present disclosure. Figure 22 A second mode, or more specifically, a charging drive mode, is shown according to an embodiment of this disclosure.

[0273] refer to Figure 5 , Figure 22 , Figure 23A and Figure 23B The second mode may include a charging-driven mode. The charging-driven mode may include a search-based charging-driven mode and a tracking-based charging-driven mode.

[0274] The search-to-charge driving mode can be a driving mode prior to sensing the pen's position. Therefore, either the first signal SG1 or the second signal SG2 can be provided to all channels included in the sensor layer 200. In other words, in the search-to-charge driving mode, the entire area of ​​the sensor layer 200 can be scanned. In the search-to-charge driving mode, when the pen PN is sensed, the sensor layer 200 can be driven for tracking charging. For example, in the tracking charging driving mode, the sensor driving unit 200C can sequentially output the first signal SG1 and the second signal SG2 to the area overlapping with the point where the pen PN is sensed, instead of outputting them to the entire sensor layer 200.

[0275] In charging drive mode, the sensor drive unit 200C can apply a first signal SG1 to one of the third pad PD3 and the fifth pad PD5, and can apply a second signal SG2 to the other pad. The second signal SG2 can be the inverse of the first signal SG1. For example, the first signal SG1 can be a sine wave.

[0276] Because the first signal SG1 and the second signal SG2 can be applied to at least two pads, the current RFS can have a current path flowing from one pad to the other. Furthermore, because the first signal SG1 and the second signal SG2 can be sinusoidal signals with an inverse relationship, the direction of the current RFS can be changed periodically. In embodiments of this disclosure, the first signal SG1 and the second signal SG2 can be square wave signals with an inverse relationship.

[0277] When the first signal SG1 and the second signal SG2 are out of phase, the first signal SG1 may be displayed on the display layer 100 (for example, see...). Figure 4 The noise caused by the signal SG2 can be canceled out by the noise that may be caused by the second signal SG2. Therefore, flickering can be eliminated in the display layer 100 and the display quality of the display layer 100 can be improved.

[0278] In embodiments of this disclosure, the first signal SG1 can be a sinusoidal signal. However, this disclosure is not limited thereto, and the first signal SG1 can also be a square wave signal. Furthermore, the second signal SG2 can have a suitable constant voltage (e.g., a predetermined constant voltage). For example, the second signal SG2 can be a ground voltage. In other words, the pad to which the second signal SG2 is applied can be grounded or is considered to be grounded. Even in this case, the current RFS can flow from one pad to another. Furthermore, even when the other pad is grounded, the first signal SG1 can be a sinusoidal or square wave signal, and therefore, the direction of the current RFS can be changed periodically.

[0279] Figure 22 The diagram shows a first signal SG1 provided to a third pad PD3 connected to a third trace 230rt1, and a second signal SG2 provided to a fourth pad PD4 connected to a fourth trace 230rt2. Current RFS can flow through a current path defined by the fourth pad PD4, the fourth trace 230rt2 connected to the fourth pad PD4, the third electrode group 230G, a portion of the third trace 230rt1 connected to the third pad PD3, and the third pad PD3. The current path can have a coil shape. Therefore, in the charging drive mode of the second mode, the resonant circuit of the pen PN can be charged by the current path.

[0280] According to some embodiments of this disclosure, a current path having a loop coil pattern can be implemented by components included in the sensor layer 200. Therefore, the electronic device 1000 (e.g., see...) Figure 1A The sensor layer 200 can be used to charge the pen PN. Therefore, since it is not necessary to separately set up or require additional components with coils for charging the pen PN, it is possible to prevent or substantially prevent an increase in the thickness, weight, and reduced flexibility of the electronic device 1000.

[0281] In charging drive mode, the first electrode group 210G, the second electrode group 220G, and the fourth electrode group 240G can be grounded, electrically floated, or a constant voltage can be applied to them. More specifically, the first electrode group 210G, the second electrode group 220G, and the fourth electrode group 240G can be floated. In this case, the current RFS may not flow to the first electrode group 210G, the second electrode group 220G, and the fourth electrode group 240G.

[0282] Figure 24A This is a view illustrating a second mode according to an embodiment of the present disclosure. Figure 24B This is a view illustrating a second mode according to an embodiment of the present disclosure.

[0283] refer to Figure 5 , Figure 24A and Figure 24B The second mode can include a charging drive mode and a pen sensing drive mode. Figure 24A and Figure 24B This is a view showing the pen sensing drive mode. Figure 24B It is an equivalent circuit diagram of the portion of the sensor layer 200 through which the first induced current Ia, the second induced current Ib, the third induced current Ic, and the fourth induced current Id generated by the pen PN can flow.

[0284] In embodiments of this disclosure, the wiring directions of one overlapping electrode and another electrode of the sensor layer 200 can be different from each other. For example, the wiring directions of the first electrode 210x and the third electrode 230x can be different from each other. Furthermore, the wiring directions of the second electrode 220x and the fourth electrode 240x can be different from each other. For example, in... Figure 24B In the sensing unit SU, the first electrode 210x and the first trace 210t can be connected to each other at the lower part of the sensing unit SU, and the third electrode 230x and the third trace 230rt1 can be connected to each other at the upper part of the sensing unit SU. The second electrode 220x and the second trace 220t can be connected to each other at the right part of the sensing unit SU, and the fourth electrode 240x and the fifth trace 240t can be connected to each other at the left part of the sensing unit SU.

[0285] The RLC resonant circuit of the pen PN can emit a magnetic field with a resonant frequency while simultaneously discharging the charged charge. The magnetic field provided in the pen PN generates a first induced current Ia in the first electrode 210x and a second induced current Ib in the second electrode 220x. Furthermore, a third induced current Ic can be generated in the third electrode 230x, and a fourth induced current Id can be generated in the fourth electrode 240x.

[0286] A first coupling capacitor Ccp1 can be formed between the third electrode 230x and the first electrode 210x, and a second coupling capacitor Ccp2 can be formed between the fourth electrode 240x and the second electrode 220x. The third induced current Ic can be transmitted to the first electrode 210x through the first coupling capacitor Ccp1, and the fourth induced current Id can be transmitted to the second electrode 220x through the second coupling capacitor Ccp2.

[0287] The sensor driving unit 200C can receive a first received signal PRX1a based on a first induced current Ia and a third induced current Ic from the first electrode 210x, and can receive a second received signal PRX2a based on a second induced current Ib and a fourth induced current Id from the second electrode 220x. The sensor driving unit 200C can detect the input coordinates of the pen PN based on the first received signal PRX1a and the second received signal PRX2a.

[0288] The sensor driving unit 200C can receive a first received signal PRX1a from the first electrode 210x and a second received signal PRX2a from the second electrode 220x. In this case, one end (e.g., opposite end) of each of the third electrode 230x and the fourth electrode 240x can be floating. Therefore, through the coupling between the first electrode 210x and the third electrode 230x and the coupling between the second electrode 220x and the fourth electrode 240x, the compensation for the sensed signal can be maximized or increased.

[0289] Furthermore, the other ends of the third electrode 230x and the fourth electrode 240x can be grounded or floating. Therefore, through the coupling between the first electrode 210x and the third electrode 230x and the coupling between the second electrode 220x and the fourth electrode 240x, the third induced current Ic and the fourth induced current Id can be sufficiently transmitted to the first electrode 210x and the second electrode 220x.

[0290] Figure 25A This is a view illustrating a method for detecting the input coordinates of a pen in a sensor layer 200 according to an embodiment of the present disclosure. Figure 25A The above reference shows Figure 7 and Figure 8AThe method described is for detecting the input coordinates of the pen PN in the sensor layer 200.

[0291] refer to Figure 7 , Figure 8A and Figure 25A The sensor layer 200 can be used to detect the input coordinates of the pen PN, and may include a second electrode group 220G, each including a first separator electrode D1 and a second separator electrode D2. The sensor layer 200 includes a fifth trace 240t, at least a portion of which overlaps with the sensing region 200A and is disposed within the gap GP between the first separator electrode D1 and the second separator electrode D2. Furthermore, within a second electrode group 220G, the length d1 of the first separator electrode D1 may be the same as or substantially the same as the length d2 of the second separator electrode D2.

[0292] In the sensor layer 200 according to the embodiment, a second-mode pen sensing drive mode can be operated to detect input coordinate data of the pen PN. The pen PN can move along each of the first path PH1, the second path PH2, and the third path PH3 to obtain input coordinate data. The pen PN moving along the first path PH1 can correspond to the state where the pen PN moves in the second direction DR2 to cross the first separator electrode D1. The pen PN moving along the second path PH2 can correspond to the state where the pen PN moves in the second direction DR2 to cross the gap GP between the first separator electrode D1 and the second separator electrode D2. The pen PN moving along the third path PH3 can correspond to the state where the pen PN moves in the second direction DR2 to cross the second separator electrode D2. First coordinate data can be obtained by the pen PN moving along the first path PH1, second coordinate data can be obtained by the pen PN moving along the second path PH2, and third coordinate data can be obtained by the pen PN moving along the third path PH3. According to the embodiment, it can be confirmed that there is no significant difference between the y-coordinate values ​​of the first coordinate data, the second coordinate data, and the third coordinate data. In other words, even when the separator structure is applied to the second electrode group 220G, and the fifth trace 240t, electrically connected to the fourth electrode group 240G, is configured to cross the gap GP between the separator electrodes within the second electrode group 220G, the pen sensing sensitivity may not change depending on the position of the pen PN. More specifically, the pen sensing sensitivity in the gap GP between the first separator electrode D1 and the second separator electrode D2, and in the area adjacent to it, may be the same as or substantially the same (or similar) to the pen sensing sensitivity in other areas. Therefore, it can be predicted that the pen sensing sensitivity is uniform or substantially uniform in all areas.

[0293] Figure 25B This is a view illustrating a method for detecting the input coordinates of a pen in a sensor layer 200 according to an embodiment of the present disclosure. Figure 25BThe above reference shows Figure 13 The method described is for detecting the input coordinates of a pen in sensor layer 200.

[0294] refer to Figure 13 and Figure 25B The sensor layer 200 can be used to detect the input coordinates of the pen PN, and may include a second electrode group 220G, each including a first separator electrode D1 and a second separator electrode D2. The sensor layer 200 includes a fifth trace 240t, at least a portion of which overlaps with the sensing region 200A and is disposed within the gap GP between the first separator electrode D1 and the second separator electrode D2. Furthermore, within one of the second electrode groups 220G, the length d1a of the first separator electrode D1 is different from the length d2a of the second separator electrode D2.

[0295] In the sensor layer 200 according to the embodiment, a second pen sensing drive mode can be operated to detect input coordinate data of the pen PN. The pen PN can move along each of the first path PH1', the second path PH2', and the third path PH3' to obtain input coordinate data. First coordinate data can be obtained by the pen PN moving along the first path PH1', second coordinate data can be obtained by the pen PN moving along the second path PH2', and third coordinate data can be obtained by the pen PN moving along the third path PH3'. According to the embodiment, there may be no significant difference between the y-coordinate values ​​of the first coordinate data, the second coordinate data, and the third coordinate data. In other words, even when the lengths of the first separator electrode D1 and the second separator electrode D2 inside the second electrode group 220G are different from each other, the pen sensing sensitivity may not change according to the position of the pen PN.

[0296] According to some of the embodiments described above, a sensor layer can be used to sense input from a pen and touch input. Therefore, since the electronic device does not require an additional separate component (e.g., a digitizer) for pen sensing, the increase in thickness, weight, and reduction in flexibility of the electronic device due to the addition of a digitizer can be prevented.

[0297] According to some of the embodiments described above, in the sensor layer, a separation structure can be applied to electrodes extending in the long axis direction, and thus, the resistance of the electrodes included in the sensing unit can be reduced. Therefore, it is possible to better ensure the frequency range (e.g., bandwidth) applicable to the signals provided to the sensor layer, and the degree of freedom in selecting the frequency can be improved.

[0298] According to some of the embodiments described above, at least some of the traces in the sensor layer can overlap with the sensing area or the display area. Therefore, the area of ​​the peripheral region of the sensor layer can be reduced. As a result, the area occupied by the peripheral region on the front surface of the electronic device can be reduced, and a narrower bezel can be achieved.

Although some embodiments have been described, those skilled in the art will readily understand that various modifications are possible in the embodiments without departing from the spirit and scope of this disclosure.
