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

[0093] Figure 1A is a perspective view of an electronic device 1000 according to an embodiment of the present disclosure. Figure 1B is a rear perspective view of the electronic device 1000 according to an embodiment of the present disclosure.

[0094] refer to Figure 1A and Figure 1B , the electronic device 1000 may be a device activated in response to an electrical signal. For example, the electronic device 1000 may display an image and may sense an external input. The external input may be a user input. The user input may include various types of external inputs such as a part of the user's body, a pen PN, light, heat, or pressure.

[0095] The electronic device 1000 may include a first display panel DP1 and a second display panel DP2. The first display panel DP1 and the second display panel DP2 may be separate panels separated from each other. The first display panel DP1 may be referred to as a main display panel, and the second display panel DP2 may be referred to as an auxiliary display panel or an external display panel.

[0096] The first display panel DP1 may include a first display DA1-F, and the second display panel DP2 may include a second display DA2-F. The second display panel DP2 may have a smaller area than the first display panel DP1. The area of ​​the first display DA1-F may be greater than the area of ​​the second display DA2-F to correspond to the sizes of the first display panel DP1 and the second display panel DP2.

[0097] In the unfolded state of the electronic device 1000, the first display DA1-F may have a plane extending substantially in the first direction DR1 and the second direction DR2. The thickness direction of the electronic device 1000 may be in a third direction DR3 intersecting the first direction DR1 and the second direction DR2. Therefore, the front surface (or upper surface) and the rear surface (or lower surface) of the elements constituting the electronic device 1000 may be defined based on the third direction DR3.

[0098] The first display panel DP1 or the first display DA1-F may include a folding area FA capable of being folded and unfolded and a plurality of non-folding areas NFA1 and NFA2 spaced apart from each other and between which the folding area FA is disposed. The second display panel DP2 may overlap one of the plurality of non-folding areas NFA1 and NFA2. For example, the second display panel DP2 may overlap the first non-folding area NFA1.

[0099] The display direction of the first image IM1a displayed on a portion of the first display panel DP1 (e.g., the second non-folding area NFA2) may be opposite to the display direction of the second image IM2a displayed on the second display panel DP2. For example, the first image IM1a may be displayed in a third direction DR3, and the second image IM2a may be displayed in a fourth direction DR4 opposite to the third direction DR3.

[0100] In an embodiment of the present disclosure, the folding area FA may be bent around a folding axis extending in a direction parallel to the long side of the electronic device 1000 (e.g., in the second direction DR2). In a folded state of the electronic device 1000, the folding area FA has a certain radius of curvature. The electronic device 1000 may be folded in an inner folding manner so that the first non-folding area NFA1 and the second non-folding area NFA2 face each other and the first display DA1-F is not exposed to the outside.

[0101] In an embodiment of the present disclosure, the electronic device 1000 may be folded in an outer folding manner so that the first display DA1-F is exposed to the outside. In an embodiment of the present disclosure, the electronic device 1000 may be folded in an inner folding manner or an outer folding manner in an unfolded state. However, the present disclosure is not necessarily limited thereto.

[0102] although Figure 1A An example of defining one folding area FA in the electronic device 1000 is shown, but the present disclosure is not necessarily limited thereto. For example, a plurality of folding axes and a plurality of folding areas corresponding thereto may be defined in the electronic device 1000, and the electronic device 1000 may be folded inwardly or outwardly around the plurality of folding axes in the unfolded state.

[0103] According to an embodiment of the present disclosure, at least one of the first display panel DP1 and the second display panel DP2 may sense input by the pen PN even without a digitizer. Since the digitizer for sensing the pen PN is omitted, an increase in thickness and weight of the electronic device 1000 and a decrease in flexibility of the electronic device 1000 due to the addition of the digitizer may not occur. Therefore, not only the first display panel DP1 but also the second display panel DP2 may be designed to sense the pen PN.

[0104] Figure 2 is a perspective view of an electronic device 1000 - 1 according to an embodiment of the present disclosure. Figure 3 is a perspective view of an electronic device 1000 - 2 according to an embodiment of the present disclosure.

Figure 3 An example in which the electronic device 1000 - 2 is a notebook computer is shown, but the electronic device 1000 - 2 may include a display panel DP.

[0106] In an embodiment of the present disclosure, the display panel DP may sense an input applied to the display panel DP. The external input may be a user input. The user input may include a touch by a part of the user's body, a pen PN (refer to Figure 1A ), various types of external inputs such as light, heat or pressure.

[0107] According to an embodiment of the present disclosure, the display panel DP may sense input by the pen PN even without a digitizer. Since the digitizer for sensing the pen PN is omitted, an increase in thickness and weight of the electronic device 1000-1 or 1000-2 due to the addition of the digitizer may not occur.

[0108] Despite Figure 1A A foldable electronic device 1000 is shown in FIG. Figure 2 , a bar-type electronic device 1000 - 1 is shown, but the present disclosure is not necessarily limited thereto. For example, the following description may be applied to various electronic devices such as a rollable electronic device, a slidable electronic device, and a stretchable electronic device.

For example, the anti-fingerprint characteristic, the anti-pollution characteristic, and the anti-scratch characteristic may be improved by the hard coating layer. For example, the hard coating layer may have a thickness of 5 μm, but is not particularly limited thereto.

[0115] The window WD may be disposed under the protective layer PL. The first adhesive layer PSA1 may be disposed between the window WD and the protective layer PL.

[0139] refer to Figure 5 , the display panel DP may include a display layer 100 and a sensor layer 200 .

[0140] The display layer 100 may be a component that basically generates an image. The display layer 100 may be an emissive display layer. For example, the display layer 100 may be an organic light-emitting display layer, an inorganic light-emitting display layer, an organic-inorganic light-emitting display layer, a quantum dot display layer, a micro-LED display layer, or a nano-LED display layer. The display layer 100 may include a base layer 110, a circuit layer 120, a light-emitting element layer 130, and an encapsulation layer 140.

[0141] The base layer 110 may be an element providing a base surface on which the circuit layer 120 is disposed. The base layer 110 may have a multi-layer structure or a single-layer structure. The base layer 110 may be a glass substrate, a metal substrate, a silicon substrate, or a polymer substrate, but is not necessarily limited thereto.

[0142] The circuit layer 120 may be disposed on the base layer 110. The circuit layer 120 may include an insulating layer, a semiconductor pattern, a conductive pattern, and a signal line. The insulating layer, the semiconductor layer, and the conductive layer may be formed on the base layer 110 by a process such as coating or deposition, and may be selectively patterned by performing a photolithography process multiple times.

[0143] The light emitting element layer 130 may be disposed on the circuit layer 120. The light emitting element layer 130 may include a light emitting element. For example, the light emitting element layer 130 may include an organic light emitting material, an inorganic light emitting material, an organic-inorganic light emitting material, a quantum dot, a quantum rod, a micro LED, or a nano LED.

[0144] The encapsulation layer 140 may be disposed on the light emitting element layer 130. The encapsulation layer 140 may protect the light emitting element layer 130 from impurities such as moisture, oxygen, and dust particles.

[0145] The sensor layer 200 may be disposed on the display layer 100. The sensor layer 200 may sense an external input applied from the outside. The sensor layer 200 may be an integrated sensor continuously formed in a process of manufacturing the display layer 100. Alternatively, the sensor layer 200 may be an external sensor attached to the display layer 100. The sensor layer 200 may be referred to as a sensor, an input sensing layer, an input sensing panel, or an electronic device for sensing input coordinates.

[0146] According to an embodiment of the present disclosure, the sensor layer 200 together with the lower conductive layer 300 can sense both input by a passive input tool such as a part of the user's body and input by an input device that generates a magnetic field with a specific resonant frequency. The input device may be referred to as a pen, an input pen, a magnetic pen, a stylus, or an electromagnetic resonance pen.

[0147] Fig. 6A and Figure 6B is a block diagram for explaining the operation of the electronic device 1000 according to an embodiment of the present disclosure.

[0148] refer to Fig. 6A , the electronic device 1000 may include a display layer 100 , a sensing module SM, a display driver 100C, a sensor driver 200C, a main driver 1000C, and a power supply circuit 1000P. The sensing module SM may include a sensor layer 200 and a lower conductive layer 300 .

[0149] The sensor module SM can sense the first input 2000 or the second input 3000 applied from the outside. Each of the first input 2000 and the second input 3000 can be an input tool that can provide a capacitance change of the sensor layer 200, or an input tool that can cause an induced current in the lower conductive layer 300. For example, the first input 2000 can be a passive input tool such as a part of the user's body. The second input 3000 can be an input made by a pen PN or an input made by an RFIC tag. For example, the pen PN can be a passive pen or an active pen.

[0150] In an embodiment of the present disclosure, the pen PN may be a device that generates a magnetic field having a specific resonant frequency. The pen PN may be configured to send an output signal based on an electromagnetic resonance scheme. The pen PN may be referred to as an input device, an input pen, a magnetic pen, a stylus, or an electromagnetic resonance pen.

[0151] The pen PN may include an RLC resonant circuit, and the RLC resonant circuit may include an inductor L and a capacitor C. In an embodiment of the present disclosure, the RLC resonant circuit may be a variable resonant circuit that varies the resonant frequency. In this case, the inductor L may be a variable inductor, and / or the capacitor C may be a variable capacitor. However, the present disclosure is not necessarily limited thereto.

[0152] The inductor L generates a current through a magnetic field formed in the sensor layer 200 and / or the lower conductive layer 300. However, the present disclosure is not necessarily limited to this. For example, when the pen PN works in an active type, the pen PN can generate a current even if no magnetic field is provided to the pen PN. The generated current is transferred to the capacitor C. The capacitor C charges the current input from the inductor L and releases the charged current to the inductor L. Thereafter, the inductor L can emit a magnetic field having a resonant frequency. The induced current can flow into the sensor layer 200 and / or the lower conductive layer 300 through the magnetic field emitted from the pen PN. The induced current can be transferred to the sensor driver 200C as a received signal (or a sensing signal or signal).

[0153] The main driver 1000C may control the overall operation of the electronic device 1000. For example, the main driver 1000C may control the operation of the display driver 100C and the sensor driver 200C. The main driver 1000C may include at least one microprocessor and may also include a graphics controller. The main driver 1000C may be referred to as an application processor, a central processing unit, or a main processor.

For example, the control signals may include an input vertical synchronization signal, an input horizontal synchronization signal, a main clock signal, and a data enable signal.

[0155] The sensor driver 200C may drive the sensor layer 200 and the lower conductive layer 300. The sensor driver 200C may receive a control signal from the main driver 1000C. The control signal may include a clock signal of the sensor driver 200C. In addition, the control signal may also include a mode determination signal for determining a driving mode of the sensor driver 200C and the sensing module SM.

[0156] The sensor driver 200C may be implemented with an integrated circuit (IC) and may be electrically connected to the sensor layer 200 and the lower conductive layer 300. For example, the sensor driver 200C may be directly mounted on the display panel in a specific area of ​​the display panel, or may be mounted on a separate printed circuit board using a chip on film (COF) method and may be electrically connected to the sensor layer 200.

[0157] The sensor driver 200C and the sensing module SM can selectively operate in a first mode or a second mode. For example, the first mode may be a mode for sensing a touch input (e.g., a first input 2000). The second mode may be a mode for sensing an input of a pen PN (e.g., a second input 3000). The first mode may be referred to as a touch sensing mode, and the second mode may be referred to as a pen sensing mode.

[0158] In an embodiment, the sensor driver 200C may drive the sensor layer 200 in a first mode, and may drive the sensor layer 200 and the lower conductive layer 300 in a second mode.

[0159] The switching between the first mode and the second mode can be performed in various ways. For example, the sensor driver 200C and the sensing module SM can be driven in the first mode and the second mode in a time-division manner, and the first input 2000 and the second input 3000 can be sensed. Optionally, the switching between the first mode and the second mode can be performed by the user's selection or a specific action of the user, or by activating or deactivating a specific application, one of the first mode and the second mode can be activated or deactivated, or the driving mode can be switched from one mode to another. In another case, when the sensor driver 200C and the sensing module SM operate alternately in the first mode and the second mode, when the first input 2000 is sensed, the sensor driver 200C and the sensing module SM can remain in the first mode, and when the second input 3000 is sensed, the sensor driver 200C and the sensing module SM can remain in the second mode.

[0160] The sensor driver 200C may calculate the input coordinate information based on the signal received from the sensor layer 200 and / or the lower conductive layer 300, and may provide a coordinate signal having the coordinate information to the main driver 1000C. The main driver 1000C performs an operation corresponding to the user input based on the coordinate signal. For example, the main driver 1000C may operate the display driver 100C to display a new application image on the display layer 100.

[0161] The power supply circuit 1000P may include a power management integrated circuit (PMIC). The power supply circuit 1000P may generate a plurality of driving voltages for driving the display layer 100, the sensor layer 200, the display driver 100C, and the sensor driver 200C. For example, the plurality of driving voltages may include a gate high voltage, a gate low voltage, a first driving voltage (e.g., an ELVSS voltage), a second driving voltage (e.g., an ELVDD voltage), an initialization voltage, etc., but is not necessarily limited to these examples.

The sensing module SM may include a sensor layer 200 and a lower conductive layer 300. The main driver 1000C may control the operations of the display driver 100C, the first sensor driver 200C1, and the second sensor driver 200C2.

[0163] The first sensor driver 200C1 may drive the sensor layer 200. The first sensor driver 200C1 may sense the first input 2000 in the first mode. The second sensor driver 200C2 may drive the sensor layer 200 and the lower conductive layer 300. The second sensor driver 200C2 may sense the second input 3000 in the second mode. In an embodiment, the first mode and the second mode may be driven by different drivers and may be independently operated.

The first pen sensing electrodes 310' may be disposed on a layer different from the layer on which the first touch sensing electrodes 210 and the second touch sensing electrodes 220 and the second pen sensing electrodes 230' are disposed, and thus the arrangement form of the first pen sensing electrodes 310' may be more freely designed.

In an embodiment, a portion of one first pen sensing electrode 230 may be included in one sensing unit 200SU.

[0215] Each of the first pen sensing electrodes 230 may be disposed between two first split touch electrodes 210 dv1 and 210 dv2 included in the first touch sensing electrode 210 .

[0216] The sensor layer 200 may further include a plurality of first traces 210t disposed in the peripheral area 200NA, a plurality of first pads PD1 connected to the first traces 210t in a one-to-one correspondence, a plurality of second traces 220t, and a plurality of second pads PD2 connected to the second traces 220t in a one-to-one correspondence.

[0217] The first trace 210t may be electrically connected to the first touch sensing electrode 210 in a one-to-one correspondence. The two first split touch electrodes 210dv1 and 210dv2 included in the first touch sensing electrode 210 may be connected to one first trace among the first traces 210t. Each of the first traces 210t may include a plurality of branch portions for connecting to the two first split touch electrodes 210dv1 and 210dv2.

In an embodiment of the present disclosure, the three second split touch electrodes 220dv1, 220dv2, and 220dv3 may be connected together in the sensing area 200A.

Therefore, the second line portion 232t and the third line portion 233t may be used as the first pen sensing electrode 230, and the same effect as that of providing the first pen sensing electrode 230 may be obtained even in the peripheral area 200NA. For example, one of the second line portion 232t and the third line portion 233t and one of the first pen sensing electrodes 230 may form a coil. Therefore, a pen located in an area adjacent to the peripheral area 200NA may also be sufficiently charged through a loop including the second line portion 232t or the third line portion 233t.

[0222] In the embodiment of the present disclosure, in order to adjust the resistance of the second line portion 232t and the resistance of the third line portion 233t, the width of the second line portion 232t and the third line portion 233t in the first direction DR1 may be adjusted. However, this is merely illustrative, and the first line portion 231t, the second line portion 232t, and the third line portion 233t may have substantially the same width.

For example, the number of the fourth traces 230t2 may correspond to the number of the first pen sensing electrodes 230. Fig.9A , four fourth traces 230t2 are shown as an example. However, it is not necessarily limited thereto, and the fourth traces 230t2 may be respectively connected to the plurality of first pen sensing electrodes 230, and may include a plurality of branch portions for connecting to the plurality of first pen sensing electrodes 230.

[0224] In an embodiment of the present disclosure, the fourth trace 230t2 and the fourth pad PD4 may be omitted, and the charging driving mode for charging the pen may be omitted.

[0231] In an implementation, the lower conductive layer 300 may include a plurality of second pen sensing electrodes 310 disposed in the sensing region 300A. The plurality of second pen sensing electrodes 310 may be referred to as fourth electrodes.

[0232] Each of the second pen sensing electrodes 310 may extend in the first direction DR1, and the second pen sensing electrodes 310 may be arranged to be spaced apart from each other in the second direction DR2. For example, the second pen sensing electrodes 310 may extend in a direction perpendicular to the extending direction of the first pen sensing electrodes 230. The second pen sensing electrodes 310 may be arranged to be spaced apart from each other in a direction perpendicular to the arrangement direction of the first pen sensing electrodes 230.

[0233] In an implementation, a portion of one second pen sensing electrode 310 may be included in one sensing unit 300SU. In one sensing unit 300SU, the portion of one second pen sensing electrode 310 may be disposed in a central portion.

In the embodiment of the present disclosure, the fifth trace 310t1 may be electrically connected to all the second pen sensing electrodes 310. For example, the fifth trace 310t1 may be electrically connected to all the second pen sensing electrodes 310.

However, this is not necessarily limited thereto, and the sixth trace lines 310t2 may be respectively connected to the plurality of second pen sensing electrodes 310 and may include a plurality of branch portions for connecting to the plurality of second pen sensing electrodes 310.

[0238] refer to 9A to 10AAccording to this embodiment, by setting in the display layer 100 (refer to Fig. 6A and Figure 6B ) provides some of the electrodes driven in the pen sensing driving mode, and the form of the electrodes driven in the pen sensing driving mode can be more freely designed. For example, when the first pen sensing electrode 230 is provided in the sensor layer 200 and the second pen sensing electrode 310 is provided in the lower conductive layer 300, the degree of freedom of design can be increased compared with when the first pen sensing electrode 230 and the second pen sensing electrode 310 are all provided in the sensor layer 200. For example, when not only the first touch sensing electrode 210 and the second touch sensing electrode 220 but also the first pen sensing electrode 230 and the second pen sensing electrode 310 are provided in the sensor layer 200, it may be difficult to form a low resistance film of the electrode, and due to space limitations, it may be difficult to arrange the first pen sensing electrode 230 and the second pen sensing electrode 310 in a loop form. On the contrary, when the second pen sensing electrode 310 is provided through the separate lower conductive layer 300 as in the present embodiment, the degree of freedom of electrode design can be increased. Therefore, the first pen sensing electrode 230 and the second pen sensing electrode 310 may all be arranged in a loop form, and a low resistance film of the electrode can be formed.

In one sensing unit 300SU, the second split pen electrodes 310dv1 and 310dv2 connected in parallel may be disposed in an upper edge portion and a lower edge portion, respectively. Fig. 10B An example is shown in which each of the second pen sensing electrodes 310 includes two second divided pen electrodes 310dv1 and 310dv2. The number of the second divided pen electrodes 310dv1 and 310dv2 included in each of the second pen sensing electrodes 310 may be variously modified.

The total area of ​​the second sensing portions 221 included in the second split touch electrodes 220dv1, 220dv2, or 220dv3 in one sensing unit 200SU may be equal to the sum of the areas of the three second sensing portions 221 having the rhombus shape.

[0249] In an embodiment, the first sensing electrode 230 may not include a split electrode separated in one sensing unit 200SU, and may be provided as one electrode. The first sensing electrode 230 may include two portions having different shapes. The first sensing electrode 230 may include a third sensing portion 231 and a third bridging portion 232. A portion having a relatively large area may be defined as the third sensing portion 231, and a portion having a relatively small area may be defined as the third bridging portion 232.

[0252] In one sensing unit 200SU, the first pen sensing electrode 230 may be disposed between the two first split touch electrodes 210dv1 and 210dv2. The third sensing portion 231 of the first pen sensing electrode 230, the first sensing portion 211 of one of the two first split touch electrodes 210dv1 and 210dv2, and the first sensing portion 211 of the other of the two first split touch electrodes 210dv1 and 210dv2 may be arranged to be spaced apart from each other in the first direction DR1.

[0253] The second bridge portion 222 of the second split touch electrodes 220dv1, 220dv2, and 220dv3 may be included in the first conductive layer 202SU. The first sensing portion 211 and the first bridge portion 212 of the first split touch electrodes 210dv1 and 210dv2, the second sensing portion 221 of the second split touch electrodes 220dv1, 220dv2, and 220dv3, and the third sensing portion 231 and the third bridge portion 232 of the first pen sensing electrode 230 may be included in the second conductive layer 204SU. However, the embodiment is not necessarily limited thereto. The second bridge portion 222 of the second split touch electrodes 220dv1, 220dv2, and 220dv3 may be included in the second conductive layer 204SU, and the first split touch electrodes 210dv1 and 210dv2, the second sensing portion 221 of the second split touch electrodes 220dv1, 220dv2, and 220dv3, and the first pen sensing electrode 230 may be included in the first conductive layer 202SU.

[0254] The first split touch electrodes 210dv1 and 210dv2 and the second split touch electrodes 220dv1, 220dv2, and 220dv3 may cross each other at the first bridge portion 212 and the second bridge portion 222.

[0255] refer to 9A to 10B and FIG. 11A to FIG. 12According to an embodiment of the present disclosure, by setting the second pen sensing electrode 310 in the lower conductive layer 300, the spatial freedom and design freedom of the sensor layer 200 can be increased. In addition, since the first pen sensing electrode 230 and the second pen sensing electrode 310 are all arranged in a loop form according to the present embodiment, the first touch sensing electrode 210 and the second touch sensing electrode 220 can be driven to sense the touch input, and the first pen sensing electrode 230 and the second pen sensing electrode 310 can be driven to sense the pen input. Therefore, for pen sensing drive, the touch sensing electrode and the pen sensing electrode may not be arranged to define a coupling capacitor. For example, the degree of freedom of arrangement of the touch sensing electrode and the pen sensing electrode can be increased. Therefore, the first touch sensing electrode 210 and the first pen sensing electrode 230 extending in the same direction can be designed to be spaced apart from each other. For example, in one sensing unit 200SU, the first touch sensing electrode 210 and the first pen sensing electrode 230 may not be arranged so that the surfaces face each other. For example, the first sensing portion 211 having a rhombus shape and the third sensing portion 231 having a rhombus shape may be arranged so that the vertices are adjacent to each other. Therefore, the spacing distance between the first touch sensing electrode 210 and the first pen sensing electrode 230 may be relatively increased, and the capacitance Cap between the first touch sensing electrode 210 and the first pen sensing electrode 230 may be reduced. Therefore, the signal-to-noise ratio (SNR) of the driving signal for sensing the touch input may be increased. As a result, the electronic device 1000 (refer to FIG. 1 ) having increased touch sensing sensitivity may be provided. Figure 1A ). In addition, the occurrence of leakage current can be reduced while sensing the pen input, and the signal-to-noise ratio (SNR) of the driving signal for sensing the pen input can be increased. As a result, the electronic device 1000 with increased pen sensing sensitivity can be provided (refer to Figure 1A ).

[0256] Reference again FIG. 11A to FIG. 12 In the embodiment of the present disclosure, the sensor layer 200 (refer to Figure 5 ) may further include a floating pattern FLP. Each of the floating patterns FLP may be electrically floated. The floating pattern FLP may be disposed between the first touch sensing electrode 210 and the first pen sensing electrode 230 adjacent to each other.

[0257] In a plan view, the floating pattern FLP may be disposed between the first touch sensing electrode 210 and the second touch sensing electrode 220 adjacent to each other in the first diagonal direction CDR1 or the second diagonal direction CDR2 and between the first pen sensing electrode 230 and the second touch sensing electrode 220. The floating pattern FLP may extend in the first diagonal direction CDR1 or the second diagonal direction CDR2. The first diagonal direction CDR1 may be a direction crossing the first direction DR1 and the second direction DR2 in a plan view defined by the first direction DR1 and the second direction DR2. The second diagonal direction CDR2 may be a direction crossing the first direction DR1, the second direction DR2, and the first diagonal direction CDR1 in a plan view defined by the first direction DR1 and the second direction DR2.

[0258] The floating pattern FLP may be included in the second conductive layer 204SU. The floating pattern FLP may be disposed on the same layer as the first split touch electrodes 210dv1 and 210dv2, the second sensing portion 221, and the first pen sensing electrode 230. However, the embodiment is not necessarily limited thereto, and the floating pattern FLP may be included in the first conductive layer 202SU.

[0259] According to the present embodiment, since the floating pattern FLP is disposed between the first touch sensing electrode 210 and the first pen sensing electrode 230, the first touch sensing electrode 210 and the first pen sensing electrode 230 may not directly face each other. Therefore, the capacitance Cap between the first touch sensing electrode 210 and the first pen sensing electrode 230 may be reduced.

[0260] Each of the first conductive layer 202SU and the second conductive layer 204SU may have a single layer structure or a multi-layer structure. For example, the first touch sensing electrode 210, the second touch sensing electrode 220, the first pen sensing electrode 230, and the floating pattern FLP may each have a single layer structure or a multi-layer structure.

[0261] In an embodiment, the pitch 200PH of the sensing units 200SU of the sensor layer 200 may be about 4 mm. However, the pitch 200PH of the sensing units 200SU of the sensor layer 200 is not necessarily limited to any one embodiment.

[0262] In an embodiment, the first touch sensing electrodes 210 and the first pen sensing electrodes 230 may be arranged such that the pitch 200PH forming one sensing unit 200SU is the same. For example, the gap between the first sensing portions 211 may be substantially the same as the gap between the third sensing portions 231 .

[0263] In an embodiment, a maximum width W21 of each of the first sensing portions 211 in the first direction DR1 may be substantially the same as a maximum width W22 of each of the second sensing portions 221 in the second direction DR2 and a maximum width W23 of each of the third sensing portions 231 in the first direction DR1.

Each of the second split touch electrodes 220dv1, 220dv2, and 220dv3 may include a second sensing portion 221 and a second bridge portion 222.

[0266] In an embodiment, the second sensing portion 221 and the second bridging portion 222 included in the second split touch electrode 220dv1, 220dv2 or 220dv3 may have an integral shape. Each of the second split touch electrodes 220dv1, 220dv2 and 220dv3 may be included in the first conductive layer 202SU. For example, the second sensing portion 221 and the second bridging portion 222 of the second split touch electrodes 220dv1, 220dv2 and 220dv3 may all be included in the first conductive layer 202SU. The first split touch electrodes 210dv1 and 210dv2 and the first pen sensing electrode 230 may be disposed in the second conductive layer 204SU, and the second split touch electrodes 220dv1, 220dv2 and 220dv3 may all be disposed on a layer different from the layer on which the first split touch electrodes 210dv1 and 210dv2 and the first pen sensing electrode 230 are disposed.

[0269] In an embodiment, the sensor layer 200 (refer to Figure 5 ) may further include a ground pattern GDP. Each of the ground patterns GDP may be grounded. For example, each of the ground patterns GDP may be considered to be grounded. The ground pattern GDP may be disposed between the first touch sensing electrode 210 and the first pen sensing electrode 230 adjacent to each other.

[0270] The ground pattern GDP may be disposed between the first split touch electrodes 210dv1 and 210dv2 and the second sensing portion 221 adjacent thereto, and between the first pen sensing electrode 230 and the second sensing portion 221 adjacent thereto. Some of the ground patterns GDP may extend along the edges of the first split touch electrodes 210dv1 and 210dv2, and other ground patterns GDP may extend along the edges of the first pen sensing electrode 230. The ground pattern GDP may be disposed on the same layer as the first touch sensing electrode 210 and the first pen sensing electrode 230. For example, the ground pattern GDP may be included in the second conductive layer 204SU.

[0271] According to the present embodiment, since the ground pattern GDP is disposed between the first touch sensing electrode 210 and the first pen sensing electrode 230, the first touch sensing electrode 210 and the first pen sensing electrode 230 may not directly face each other. Therefore, the capacitance between the first touch sensing electrode 210 and the first pen sensing electrode 230 may be reduced.

In an embodiment, the fourth sensing portion 311 may have a rhombus shape, and each of the fourth sensing portions 311 has a maximum width W31 in the second direction DR2. The fourth bridge portion 312 may connect the fourth sensing portions 311 adjacent to each other and may have a strip shape extending in the first direction DR1.

[0284] In one sensing unit 300SU, the second sensing electrode 310 may include four fourth sensing portions 311 and three fourth bridging portions 312. Among the four fourth sensing portions 311, two fourth sensing portions 311 may include the entire area of ​​the rhombus shape, and the remaining two fourth sensing portions 311 may include a partial area corresponding to half of the rhombus shape (e.g., a half rhombus shape).

In an embodiment, the second touch sensing electrode 220 may be arranged in a central portion, one second split pen electrode 310dv1 may be arranged in an upper edge portion, and another second split pen electrode 310dv2 may be arranged in a lower edge portion. Since the second touch sensing electrode 220 and the second pen sensing electrode 310 are arranged not to overlap with each other, a coupling capacitor may not be defined between the second touch sensing electrode 220 and the second pen sensing electrode 310. Therefore, leakage current in a pen sensing driving mode may be reduced, and a signal-to-noise ratio (SNR) may be increased. Therefore, an electronic device 1000 (refer to Figure 1A ).

The two second split touch electrodes 220dv1 and 220dv2 may be respectively disposed in the upper edge portion and the lower edge portion of the sensing unit 200SU. Each of the two second split touch electrodes 220dv1 and 220dv2 may include a second sensing portion 221 and a second bridge portion 222.

[0320] In the embodiment of the present disclosure, the sensor layer 200 (refer to Figure 5 ) may further include a floating pattern FLP and a dummy pattern DFLP. The floating pattern FLP and the dummy pattern DFLP may each be electrically floated.

For example, the dummy pattern DFLP may be disposed in the central portion of the sensing unit 200SU. Each of the dummy patterns DFLP may have a rhombus shape. Four dummy patterns DFLP may be disposed in one sensing unit 200SU. Among the four dummy patterns DFLP, two dummy patterns DFLP may include the entire area of ​​the rhombus shape, and the remaining two dummy patterns DFLP may include a partial area corresponding to half of the rhombus shape (e.g., a half rhombus shape).

In an embodiment, the second pen sensing electrode 310 may be arranged in a central portion. Since the second touch sensing electrode 220 and the second pen sensing electrode 310 are arranged not to overlap with each other, a coupling capacitor may not be defined between the second touch sensing electrode 220 and the second pen sensing electrode 310. Therefore, leakage current in the pen sensing driving mode may be reduced, and a signal-to-noise ratio (SNR) may be increased. Therefore, an electronic device 1000 (reference) having increased sensing sensitivity may be provided Figure 1A ). However, the embodiment is not necessarily limited thereto, and by Fig.19B and Fig. 27 The second touch sensing electrode 220 and the second pen sensing electrode 310 may be arranged to overlap each other.

[0325] refer to Fig.28A and Fig.28B In an embodiment, the electrode EE may include two parts having different shapes. The electrode EE may include a sensing part P1 and a bridging part P2. The part having a relatively large area may be defined as the sensing part P1, and the part having a relatively small area may be defined as the bridging part P2. The maximum width W1a or W1b of the sensing part P1 in the second direction DR2 (or, in a direction perpendicular to the extension direction of the electrode EE) may be greater than the width W2a or W2b of the bridging part P2 in the second direction DR2 (or, in a direction perpendicular to the extension direction of the electrode EE). The sensing part P1 may alternate with the bridging part P2 in the first direction DR1 (or, in the extension direction of the electrode EE).

[0326] The maximum width W1a or W1b of the sensing portion P1 in the second direction DR2 and the width W2a or W2b of the bridge portion P2 in the second direction DR2 may be designed differently. Fig.28AAs shown in FIG. 1 , the maximum width W1a of the sensing portion P1 in the second direction DR2 and the width W2a of the bridge portion P2 in the second direction DR2 may be designed so that the difference therebetween is relatively large, and as shown in FIG. Fig.28B As shown in FIG. 2 , a maximum width W1 b of the sensing portion P1 in the second direction DR2 and a width W2 b of the bridge portion P2 in the second direction DR2 may be designed such that a difference therebetween is relatively small.

[0327] refer to Fig.28C In an embodiment, the electrode EE may have a strip shape in which a width Wc in the second direction DR2 (or in a direction perpendicular to the extension direction of the electrode EE) is substantially constant.

In addition, signal lines 210_S1 and 210_S2 connecting the sensor driver 200C and the two first touch sensing electrodes 210_1 and 210_2 and signal lines 220_S1 and 220_S2 connecting the sensor driver 200C and the two second touch sensing electrodes 220_1 and 220_2 are shown.

[0330] In the first mode 1-M, one of the first touch sensing electrode 210 and the second touch sensing electrode 220 may operate as a transmitter electrode, and the other of the first touch sensing electrode 210 and the second touch sensing electrode 220 may operate as a receiver electrode. Fig.29A, the first touch sensing electrode 210 is shown as a transmitter electrode, and the second touch sensing electrode 220 is shown as a receiver electrode. The driving signals TS1 and TS2 may be provided to the first end of the first touch sensing electrode 210, and the sensor driver 200C may receive the sensing signals RS1 and RS2 from the second touch sensing electrode 220. The sensor driver 200C may sense the first input 2000 (reference 2000) by sensing a change in capacitance formed between the first touch sensing electrode 210 and the second touch sensing electrode 220. Fig. 6A and Figure 6B ).

[0331] refer to Fig.29A and Fig.29B In an embodiment, the first mode 1-M may include a mutual capacitance detection mode. The sensor driver 200C may sequentially provide a transmission signal TS to the first touch sensing electrode 210, and may detect the first input 2000 (reference signal RS) detected by the second touch sensing electrode 220. Fig. 6A and Figure 6B For example, the sensor driver 200C may be configured to sense a change in mutual capacitance between the first touch sensing electrode 210 and the second touch sensing electrode 220 and calculate the input coordinates.

[0332] Fig.29B An example is shown in which a transmission signal TS is provided to one first touch sensing electrode 210 and a reception signal RS is output from the second touch sensing electrode 220.

The sensor driver 200C can detect the first input 2000 (refer to Fig. 6A and Figure 6B ) input coordinates.

[0333] According to an embodiment of the present disclosure, in the mutual capacitance detection mode, the first sensing electrode 230 and the second sensing electrode 310 (refer to Fig. 8A ) can be all grounded. Therefore, the first sensing electrode 230 and the second sensing electrode 310 (reference Fig. 8A In the embodiment of the present disclosure, a reference potential may be applied to the first sensing electrode 230 and the second sensing electrode 310 (reference potential). Fig. 8A In the embodiment of the present disclosure, a signal in phase with the transmission signal TS may be applied to the first sensing electrode 230 and the second sensing electrode 310 (refer to Fig. 8AIn this case, the first pen sensing electrode 230 and the second pen sensing electrode 310 (refer to Fig. 8A ) introduces noise.

Fig. 30B The operation of the sensor layer 200 in the second mode 2-M is shown according to an embodiment of the present disclosure. Fig.31A Graphs depicting waveforms of the first signal SG1 and the second signal SG2 according to an embodiment of the present disclosure are shown. Fig.31B Graphs depicting waveforms of the first signal SG1a and the second signal SG2a according to an embodiment of the present disclosure are shown. Fig.31C Graphs depicting waveforms of the first signal SG1 and the second signal SG2b according to an embodiment of the present disclosure are shown.

[0335] refer to Fig. 30A The sensing module SM may include a first sensing electrode 230 and a second sensing electrode 310 that are insulated from each other and intersect each other. The first sensing electrode 230 may be included in the sensor layer 200 (refer to Fig. 6A and Figure 6B ), and the second pen sensing electrode 310 may be included in the lower conductive layer 300 (reference Fig. 6A and Figure 6B ). Fig. 30A , two first sensing electrodes 230_1 and 230_2 among the plurality of first sensing electrodes 230 and two second sensing electrodes 310_1 and 310_2 among the plurality of second sensing electrodes 310 are shown. In addition, signal lines 230_S1 and 230_S2 connecting the sensor driver 200C and the two first sensing electrodes 230_1 and 230_2 and signal lines 310_S1 and 310_S2 connecting the sensor driver 200C and the two second sensing electrodes 310_1 and 310_2 are shown.

[0336] The second mode 2-M may include a charging driving mode and a pen sensing driving mode. Fig. 30A is a view for explaining the charge driving mode. According to an embodiment, during the charge driving mode, the first pen sensing electrode 230 may receive up signals ULSa and ULSb from the sensor driver 200C and may perform charge driving.

[0337] refer to Fig. 30B and Fig.31A , the second mode 2-M may include a charging driving mode and a pen sensing driving mode. Fig. 30B is a view for explaining the charging driving mode.

[0338] In the charging driving mode according to the embodiment, the sensor driver 200C may apply the first signal SG1 to at least one of the third pad PD3 and the fourth pad PD4, and may apply the second signal SG2 to at least one other pad. The second signal SG2 may be an inverse signal of the first signal SG1. For example, the first signal SG1 may be a sinusoidal signal.

[0339] although Fig. 30B An example is shown in which the first signal SG1 is applied to one pad and the second signal SG2 is applied to another pad, but the present disclosure is not necessarily limited thereto. For example, the first signal SG1 may be applied to two or more pads, and the second signal SG2 may be applied to two or more other pads.

[0340] Since the first signal SG1 and the second signal SG2 are applied to at least two pads, the current can have a current path flowing through at least one pad to at least one other pad. In addition, since the first signal SG1 and the second signal SG2 are sinusoidal signals with an anti-phase relationship, the direction of the current can change periodically.

[0341] refer to Fig. 30B and Fig.31B , the first signal SG1a and the second signal SG2a may be square wave signals. The second signal SG2a may be an inverted signal of the first signal SG1a. Since the first signal SG1a and the second signal SG2a are applied to at least two pads, the current may have a current path that flows through at least one pad to at least one other pad. In addition, since the first signal SG1a and the second signal SG2a are square wave signals having an anti-phase relationship, the direction of the current may change periodically.

[0342] Fig.31A and Fig.31B The first signal SG1 or SG1a shown in FIG. 1 has an anti-phase relationship with the second signal SG2 or SG2a. Therefore, the first signal SG1 or SG1a is displayed on the display layer 100 (reference Figure 5 ) can offset the noise caused by the second signal SG2 or SG2a. Figure 5 ) will not appear flickering, and the display layer 100 (reference Figure 5 ) display quality.

[0343] refer to Fig. 30B and Fig.31C, the first signal SG1 may be a sinusoidal signal. However, it is not necessarily limited thereto, and the first signal SG1 may be a square wave signal. The second signal SG2b may have a specific constant voltage. For example, the second signal SG2b may be a ground voltage. For example, the pad to which the second signal SG2b is applied may be considered to be grounded. Even in this case, current may flow from at least one pad to at least one other pad. In addition, even if at least one other pad is grounded, the direction of the current may change periodically because the first signal SG1 is a sinusoidal signal or a square wave signal.

[0344] Reference again Fig. 30B , the second signal SG2 may be provided to a third pad PD3 connected to a third trace 230t1, and the first signal SG1 may be provided to a fourth pad PD4 connected to the first pen sensing electrode 230. The current may flow along a current path defined by the fourth pad PD4, the fourth trace 230t2 connected to the fourth pad PD4, the first pen sensing electrode 230, the portion of the third trace 230t1 connected to the third pad PD3, and the third pad PD3. The current path may have the form of a coil. Therefore, in the charging drive mode of the second mode 2-M, the pen PN (reference Fig. 6A and Figure 6B )'s resonant circuit can be charged via the current path.

[0345] According to an embodiment of the present disclosure, in the charging driving mode, the first touch sensing electrode 210, the second touch sensing electrode 220, and the second pen sensing electrode 310 may be grounded or electrically floating, or may have a constant voltage applied thereto. For example, the first touch sensing electrode 210, the second touch sensing electrode 220, and the second pen sensing electrode 310 may be floating. In this case, current may not flow to the first touch sensing electrode 210, the second touch sensing electrode 220, and the second pen sensing electrode 310.

[0346] Fig.32 The operation of the sensing module SM in the second mode 2-M according to an embodiment of the present disclosure is shown.

[0347] refer to Fig.32 The sensing module SM may include a first sensing electrode 230 and a second sensing electrode 310 that are insulated from each other and intersect each other. The first sensing electrode 230 may be included in the sensor layer 200 (refer to Fig. 6A and Figure 6B ), and the second pen sensing electrode 310 may be included in the lower conductive layer 300 (reference Fig. 6A and Figure 6B )middle.
