[0038] Hereinafter, aspects of some embodiments of the present disclosure will be described with reference to the drawings.

[0039] Figure 1 is a perspective view of an electronic device according to some embodiments of the present disclosure.

For example, the electronic device ELD may be a mobile phone, a foldable mobile phone, a laptop computer, a television, a tablet computer, a vehicle navigation system, a game console, or a wearable device, but is not limited thereto according to embodiments of the present disclosure. As an example for the purpose of description, Figure 1 exemplarily shows that the electronic device ELD is a mobile phone.

[0041] The electronic device ELD can display an image and can sense an external input applied from an external unit. The external input can be an input from a user. The user input can include various types of external inputs such as a part US_F of the user's body, a pen PN, light, heat, or pressure. The user input can include all inputs that can change the capacitance of the sensor layer.

[0042] An active area AA and a peripheral area NAA can be defined in the electronic device ELD. The electronic device ELD can display an image at the active area AA. The active area AA can include a plane defined by a first direction DR1 and a second direction DR2. The peripheral area NAA can surround the periphery of the active area AA (or be located outside the occupied area of the active area AA). According to some embodiments of the present disclosure, the peripheral area NAA can be omitted.

[0043] The thickness direction of the electronic device ELD can be parallel to a third direction DR3 that intersects the first direction DR1 and the second direction DR2. Accordingly, a front surface (or an upper surface) and a rear surface (or a lower surface) of the components constituting the electronic device ELD can be defined based on the third direction DR3.

[0044] Figure 1 An exemplary bar-shaped electronic device ELD is shown, but the embodiments according to the present disclosure are not limited thereto. For example, the following description can be applied to various electronic devices ELD such as a foldable electronic device, a rollable electronic device, or a slidable electronic device.

[0047] A display area and a non-display area corresponding to the active area AA (see Figure 1 ) and the peripheral area NAA (see Figure 1 ) of the electronic device ELD can be defined in the display layer DP.

[0048] The display layer DP according to some embodiments of the present disclosure may be a light-emitting display layer, but the embodiments of the present disclosure are not limited thereto.

According to some embodiments of the present disclosure, the sensor layer ISP may be formed on the display layer DP through a continuous process. That is, when the sensor layer ISP is directly located on the display layer DP, the internal adhesive layer is not located between the sensor layer ISP and the display layer DP.

[0050] The electronic device ELD may further include an optical member located on the display module DM. The optical member may be an anti-reflection layer that can reduce the external light reflectance. The optical member may include a polarizer and a phase retarder. The polarizer and the phase retarder may be of the stretching type or the coating type. The optical axis of the coating type optical film is defined according to the stretching direction of the functional film.

[0055] Figure 3 is a cross-sectional view of a display module according to some embodiments of the present disclosure.

[0056] [[ID=Z7]]Referring to Figure 3 , the display module DM may include a display layer DP and a sensor layer ISP.

[0057] The display layer DP may include a substrate layer BL, a circuit layer DP-CL, a light-emitting element layer DP-ED, and a encapsulation layer TFL.

[0058] The substrate layer BL may be a member providing a substrate surface on which the circuit layer DP-CL is located. The substrate layer BL may have a multi-layer structure or a single-layer structure. The substrate layer BL may be a glass substrate, a metal substrate, a silicon substrate, a polymer substrate, etc., but is not limited thereto according to embodiments of the present disclosure.

[0059] The circuit layer DP-CL may be located on the substrate layer BL. The circuit layer DP-CL may include an insulating layer, a semiconductor pattern, a conductive pattern, signal lines, etc. The insulating layer, the semiconductor layer, and the conductive layer may be formed on the substrate layer BL by means such as coating and deposition, and the insulating layer, the semiconductor layer, and the conductive layer may be selectively patterned through a plurality of lithography processes.

[0060] The light-emitting element layer DP-ED may be located on the circuit layer DP-CL. The light-emitting element layer DP-ED may include light-emitting elements. For example, the light-emitting element layer DP-ED may include an organic light-emitting material, an inorganic light-emitting material, an organic-inorganic light-emitting material, quantum dots, quantum rods, micro LEDs, or nano LEDs.

[0061] The encapsulation layer TFL may be located on the light-emitting element layer DP-ED. The encapsulation layer TFL may protect the light-emitting element layer DP-ED from foreign substances or contaminants such as moisture, oxygen, and dust particles.

[0062] The sensor layer ISP may be located on the display layer DP. The sensor layer ISP may sense an external input applied from an external unit. The sensor layer ISP may be an integrated sensor continuously formed during the process of manufacturing the display layer DP, or the sensor layer ISP may be an external sensor attached to the display layer DP.

[0063] Figure 4 is a view for describing the operation of an electronic device according to some embodiments of the present disclosure.

[0064] Referring to Figure 4 , the electronic device ELD may include a display layer DP, a sensor layer ISP, a display driving unit 100C, a sensor driving unit 200C, a main driving unit 1000C, and a power circuit 1000P.

[0065] The sensor layer ISP can sense a first input 2000 and a second input 3000 applied from an external unit. The first input 2000 and the second input 3000 can be input methods that can provide a change in capacitance of the sensor layer ISP, or can be input methods that can induce an induced current in the sensor layer ISP. For example, the first input 2000 can be a passive input mechanism such as a user's body. The second input 3000 can be an input from a pen PN or an input from a radio frequency integrated circuit (RFIC) tag. For example, the pen PN can be a passive pen or an active pen.

[0066] According to some embodiments of the present disclosure, the pen PN can be a device that generates a magnetic field having a resonant frequency (e.g., a set or predetermined resonant frequency). The pen PN can be configured to transmit an output signal based on an electromagnetic resonance method. The pen PN can be referred to as an input device, an input pen, a magnetic pen, a stylus, or an electromagnetic resonance pen.

[0067] The pen PN can include an RLC resonance circuit, and the RLC resonance circuit can include an inductor L and a capacitor C. According to some embodiments of the present disclosure, the RLC resonance circuit can be a variable resonance circuit having a variable resonance frequency. In this case, the inductor L can be a variable inductor and / or the capacitor C can be a variable capacitor, but is not limited thereto according to the embodiments of the present disclosure.

[0068] The inductor L generates a current through the magnetic field formed in the sensor layer ISP. However, it is not limited thereto according to the embodiments of the present disclosure. For example, when the pen PN operates as an active type, even when the pen PN does not receive a magnetic field from an external unit, the pen PN can generate a current. The generated current is transmitted 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 having a resonant frequency. The induced current can flow in the sensor layer ISP through the magnetic field emitted by the pen PN, and the induced current as a received signal (or sensed signal) can be transmitted to the sensor driving unit 200C.

[0069] The main driving unit 1000C can control the overall operation of the electronic device ELD. For example, the main driving unit 1000C can control the operations of the display driving unit 100C and the sensor driving unit 200C. The main driving unit 1000C can include at least one microprocessor and can also include a graphics controller. The main driving unit 1000C can be referred to as an application processor, a central processing unit, or a main processor.

[0070] The display driving unit 100C can drive the display layer DP. The display driving unit 100C can receive image data and control signals from the main driving unit 1000C. The control signals can include various signals. For example, the control signals can include an input vertical synchronization signal, an input horizontal synchronization signal, a main clock, a data enable signal, etc.

[0071] The sensor driving unit 200C can drive the sensor layer ISP. The sensor driving unit 200C can receive control signals from the main driving unit 1000C. The control signals can include the clock signal of the sensor driving unit 200C. In addition, the control signals can also include a mode determination signal for determining the driving mode of the sensor driving unit 200C and the sensor layer ISP.

[0072] The sensor driving unit 200C can be implemented as an integrated circuit (IC) and electrically connected to the sensor layer ISP. For example, the sensor driving unit 200C can be directly mounted on the area of the display layer DP (e.g., a set or predetermined area), or mounted on a separate printed circuit board using the chip-on-film (COF) method and electrically connected to the sensor layer ISP.

[0073] The sensor driving unit 200C and the sensor layer ISP can selectively operate in a first mode or a second mode. For example, the first mode can be a mode for sensing a touch input (e.g., the first input 2000). The second mode can be a mode for sensing an input from the pen PN (e.g., the 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.

[0074] The switching between the first mode and the second mode can be performed in various ways. For example, the sensor driving unit 200C and the sensor layer ISP can be driven in the first mode and the second mode in a time-division manner, and can sense the first input 2000 and the second input 3000. Optionally, the switching between the first mode and the second mode can be generated by the user's selection or by a specific action of the user, any one of the first mode and the second mode can be activated or deactivated by activating or deactivating a specific application, or the current mode can be switched from one of the first mode and the second mode to the other. Optionally, while the sensor driving unit 200C and the sensor layer ISP alternately operate in the first mode and the second mode, when the first input 2000 is sensed, the first mode is maintained, or when the second input 3000 is sensed, the second mode is maintained.

[0075] The sensor driving unit 200C can calculate the input coordinate information based on the signal received from the sensor layer ISP, and provide a coordinate signal with the coordinate information to the main driving unit 1000C. The main driving unit 1000C performs 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 so that a new application image is displayed on the display layer DP.

[0076] The power supply circuit 1000P can include a power management integrated circuit (PMIC). The power supply circuit 1000P can generate a plurality of driving voltages for driving the display layer DP, the sensor layer ISP, the display driving unit 100C, and the sensor driving unit 200C. For example, the plurality of driving voltages can include a first driving voltage (e.g., ELVSS voltage), a second driving voltage (e.g., ELVDD voltage), an initialization voltage, etc., but are not limited to the above examples according to the embodiments of the present disclosure.

The circuit layer DP-CL can include an insulating layer, a semiconductor pattern, a conductive pattern, signal lines, etc. The insulating layer, the semiconductor layer, and the conductive layer can be formed on the substrate layer BL in such a manner as coating and deposition, and then the insulating layer, the semiconductor layer, and the conductive layer can be selectively patterned through a plurality of photolithography processes. Thereafter, the semiconductor pattern, the conductive pattern, and the signal lines included in the circuit layer DP-CL can be formed.

[0079] At least one inorganic layer is formed on the upper surface of the substrate layer BL. According to some embodiments, it is shown that the display layer DP includes a buffer layer BFL.

[0082] The conductivity of the first region is greater than that of the second region, and the first region basically serves as an electrode or a signal line. The second region may substantially correspond to the active region (or channel region) of the pixel transistor TR-P. In other words, a part of the semiconductor pattern may be the active region of the transistor, and another part thereof may be the source region or the drain region of the transistor.

Figure 5 Shown is a part of the signal transmission region SCL formed in the first region of the semiconductor pattern. According to some embodiments, the signal transmission region SCL may be electrically connected to the pixel transistor TR-P in a plane.

The first connection electrode CNE1 can be located on the third insulating layer IL3. The first connection electrode CNE1 can be connected to the signal transmission region SCL through a contact hole CNT1 that passes through the first insulating layer IL1, the second insulating layer IL2, and the third insulating layer IL3.

The resistance of the wiring for transmitting the second touch signal RS (see Figure 6 ) can be reduced. Thus, the bandwidth of the wiring can be increased. The range of selectable frequencies is increased, so it is easier to avoid noise, and the touch performance can be relatively improved. Therefore, an electronic device ELD with relatively improved sensing reliability can be provided (see Figure 1 ).

[0144] The plurality of second sub-electrodes SME2 may be electrically connected to the second line L2 through the second contact hole CCH2. The second line L2 may extend in the first direction DR1.

[0145] The first line L1 and the second line L2 may be spaced apart from each other in the second direction DR2, and the plurality of first sub-electrodes SME1 and the plurality of second sub-electrodes SME2 are disposed between the first line L1 and the second line L2.

[0146] The third line L3 can be connected to one of the plurality of first sub-electrodes SME1. The third line L3 can extend in the second direction DR2. The third line L3 can be located on the first sensor insulating layer IIL1. The second sensor insulating layer IIL2 can cover the third line L3.

[0150] Figure 9 Exemplarily, a plurality of first electrodes RE and a plurality of second electrodes TE having a strip shape are shown, but the shapes of the plurality of first electrodes RE and the plurality of second electrodes TE according to some embodiments of the present disclosure are not limited thereto. For example, the plurality of first electrodes RE and the plurality of second electrodes TE can have a diamond pattern shape.

[0151] Figure 12 is a plan view showing a part of an electronic device according to some embodiments of the present disclosure, Figure 13 is a view showing the operation of an electronic device according to some embodiments of the present disclosure. In Figure 12 the description of, the components described by Figure 7 are denoted by the same reference numerals, and some of their repeated descriptions can be omitted.

[0152] Refer to Figure 12 and Figure 13When the user uses the pen PN, the user can use the pen PN while the user's arm is placed on the effective area SA. In this case, the arm acts as a large-area conductor TC, extending in the same direction as the third line L3 or the fourth line L4, and generating a coupling capacitor C_TC. For example, when the third line L3 of the leftmost first sub-electrode SME1 among the multiple first sub-electrodes SME1 directly connected to the first electrode RE1 of the first row overlaps with the large-area conductor TC on the plane, the capacitance of the coupling capacitor C_TC corresponding to the first sub-electrode SME1 increases.

[0153] When viewed on a plane (e.g., in a floor plan), and when the large-area conductor TC overlaps with the third line L3 in the first region AR1, the large-area conductor TC does not overlap with the second region AR2 spaced from the first region AR1 in the first direction DR1. Therefore, the large-area conductor TC can not overlap with the fourth line L4 on the plane. That is, when one of the third line L3 and the fourth line L4 overlaps with the large-area conductor TC, the other of the third line L3 and the fourth line L4 does not overlap with the large-area conductor TC.

[0154] The third line L3 and the fourth line L4 connected to the multiple first electrodes RE can be spaced apart from each other in the first direction DR1, and at least one of the multiple first sub-electrodes SME1 or at least one of the multiple second sub-electrodes SME2 is placed between the third line L3 and the fourth line L4. That is, the third line L3 can be located in the first region AR1, and the fourth line L4 can be located in the second region AR2 spaced from the first region AR1 in the first direction DR1.

[0155] The third line L3 can be represented as a first resistor R_L3 and a first capacitor C_L3.

[0156] When the coupling capacitor C_TC is formed on the third line L3 through the large-area conductor TC, the fourth line L4 can be spaced apart from the third line L3 by a distance (e.g., a set or predetermined distance) in the first direction DR1, and thus does not overlap with the large-area conductor TC. That is, the fourth line L4 can be spatially separated from the large-area conductor TC. Therefore, no coupling capacitor is formed in the fourth line L4.

[0157] The fourth line L4 can be represented as a second resistor R_L4 and a second capacitor C_L4.

[0158] The third line L3 and the fourth line L4 can be connected to the sensor driving unit 200C through a pad (also known as a "bond pad" or "landing pad") portion PAD. The sensor driving unit 200C can include an input detection circuit 200C3.

[0159] The input detection circuit 200C3 may include a plurality of signal receiving units 201C3, a plurality of conversion circuits 202C3, and a signal processing unit 203C3.

[0160] The plurality of signal receiving units 201C3 may amplify and output the received signals. The plurality of signal receiving units 201C3 may be connected to the pad portion PAD. That is, the third line L3 may be electrically connected to one of the plurality of signal receiving units 201C3, and the fourth line L4 may be electrically connected to another one of the plurality of signal receiving units 201C3.

[0161] The plurality of signal receiving units 201C3 may output a signal corresponding to the voltage difference between the first terminal and the second terminal through the output terminal. Each of the plurality of signal receiving units 201C3 may be implemented as an analog front end (AFE) including an amplifier AMP, a capacitor Ca, and a switch SWr. The amplifier AMP may include an operational (OP) amplifier.

[0162] The first terminal of the amplifier AMP may be electrically connected to the pad portion PAD. A reference voltage Vref may be provided to the second terminal of the amplifier AMP.

[0163] The capacitor Ca and the switch SWr may be connected in parallel between the first terminal and the output terminal of the amplifier AMP.

[0164] The plurality of conversion circuits 202C3 may convert the analog signals input from the plurality of signal receiving units 201C3 into digital signals. Each of the plurality of conversion circuits 202C3 may include an analog-to-digital converter ADC.

[0165] The signal processing unit 203C3 may process the conversion signals (digital signals) from the plurality of conversion circuits 202C3, and compensate for ghost touches based on the signal processing results.

[0166] The first sensing signal sensed by the third line L3 may include noise caused by the large-area conductor TC. In this case, the second sensing signal sensed by the fourth line L4 may be a signal that does not include noise.

[0167] The signal processing unit 203C3 may calculate the difference between the first sensing signal converted into a digital signal and the second sensing signal. The signal processing unit 203C3 may compensate for the coordinates based on this difference.

[0168] The sensor driving unit 200C may compensate for the coordinates based on the difference between the first sensing signal sensed by the third line L3 and the second sensing signal sensed by the fourth line L4. Malfunctions such as ghost touches caused by the large-area conductor TC can be prevented or reduced.

[0169] According to the present disclosure, when a large-area conductor TC is superimposed on any one of a third line L3 and a fourth line L4 and thus a coupling capacitor C_TC is formed at a specific node, the other one of the third line L3 and the fourth line L4 is not superimposed on the large-area conductor TC. A signal processing unit 203C3 may receive a first sensing signal and a second sensing signal. The first sensing signal is obtained by converting a signal that generates noise by the coupling capacitor C_TC into a digital signal, and the second sensing signal is obtained by converting a signal that does not generate noise into a digital signal. The signal processing unit 203C3 may extract only a noise signal corresponding to the noise based on a difference between the first sensing signal and the second sensing signal. The signal processing unit 203C3 may compensate coordinates based on the noise signal. Accordingly, an electronic device ELD having relatively improved sensing reliability can be provided (see Figure 1 ).

[0170] According to the above description, when a large-area conductor is superimposed on any one of a third line and a fourth line such that a coupling capacitor is formed at a specific node, the other one of the third line and the fourth line is not superimposed on the large-area conductor. A sensor driving unit may receive a first sensing signal and a second sensing signal. The first sensing signal is obtained by converting a signal that generates noise by the coupling capacitor into a digital signal, and the second sensing signal is obtained by converting a signal that does not generate noise into a digital signal. The sensor driving unit may extract only a noise signal corresponding to the noise based on a difference between the first sensing signal and the second sensing signal. The sensor driving unit may compensate coordinates based on the noise signal. Accordingly, an electronic device having relatively improved sensing reliability can be provided.

[0171] Although the above has been described with reference to aspects of some embodiments of the present disclosure, it will be understood that those skilled in the art or those of ordinary skill in the art can make various modifications and changes to the present disclosure without departing from the spirit and technical scope of the present disclosure described in the appended claims and their equivalents.
