[Technical field]

[0001] The present invention detects the touch position, drives the stylus pen, and The present invention relates to a multi-function touch input device capable of detecting [Background technology]

[0002] FIG. 1 shows a conventional flexible display panel with a stylus pen 10 positioned in a certain position. To explain that the output voltage (Vout) of the CVA (Capacitor Voltage Amplitude) changes, 1 is a schematic diagram for

[0003] Referring to FIG. 1, the CV is generated according to the position of the pen 10 on the flexible display panel. The reason why the output of A is different is that the impedance on both sides of the sensing line centered on the pen 10 The problem is that the impedance ratio changes.

[0004] Metal Mesh based on the long axis of conventional flexible display panels The resistance R of the touch sensor is about 1.2 k (ohm), and the capacitor C is about 250 pF.

[0005] Based on 10 distributed models, the driving frequency is 300kHz. The impedance of the capacitor is about 200 times higher than that of the resistor (120 ohms vs. .1 / (2=*300k*25pF)=21k(ohm) is larger. Therefore, the capacitor is the main This is the cause.

[0006] FIG. 2 shows the output voltage (Vout1, Vout2) of the CVA depending on the position of the pen 10 in FIG. This is a diagram for explaining the above through current sensing. FIG. 3 shows a case where the output voltages (Vout1, Vout2) of the CVA are different depending on the position of the pen 10 in FIG. This is a diagram for explaining the above through voltage sensing. .

[0007] 2 and 3, the output of the CVA depends on the position of the pen 10 on the sensing line. That is, the closer the pen 10 is to the sensing circuit unit 50, the higher the output voltage of the CVA. The output voltage of the CVA becomes smaller as the distance from the sensing circuit unit 50 increases. Summary of the Invention [Problem to be solved by the invention]

[0079] FIG. 5 illustrates a touch input device according to the embodiment of the present invention in a touch sensing mode (or a 2D sensing mode). 13 is a diagram showing the case where the device operates in a switching mode.

[0080] 4 and 5, in the touch sensing mode, the control unit 500 A plurality of driving circuits for sensing are electrically connected to the first pattern 101 of the sensor part 100. The control unit 500 controls a number of switches SW to set a number of first patterns. The conductive traces connected to the line 101 can be electrically connected to a number of drive circuitry. can.

[0081] In addition, the control unit 500 controls a number of sensing circuits for touch sensing in the sensor unit 100. The control unit 500 can be electrically connected to the third pattern 103 of the By controlling the switch sw, the conductive traces connected to the third pattern 103 are connected to the multiple sensing The sensing circuit unit may be electrically connected to the sensing circuit unit.

[0082] In the touch sensing mode, the control unit 500 detects a touch on a plurality of first patterns 101. A driving signal (or a touch driving signal) for touch sensing is applied simultaneously or sequentially to multiple The sensing signal (or the touch sensing signal) is received from the third pattern 103. A plurality of sensing circuits of the control unit 500 electrically connected to the third pattern 103 receive the input The capacitance change amount information included in the detected signal can be output as a predetermined voltage value. The control unit 500 can process the output voltage value to detect the touch position.

[0083] In FIG. 5, the control unit 500 is not electrically connected to the second patterns 102. , the capacitive coupling between the first pattern 101 and the second pattern 102 In order to prevent the occurrence of reactive coupling, a number of driving circuit parts are provided on a number of second patterns 102. In this case, the control unit 500 can electrically connect the first patterns 10 to each other. The same driving signal as that applied to the first pattern 102 is applied to the second pattern 102. Alternatively, the control unit 500 may control the first patterns 101 to have a plurality of driving signals.

[0084] FIG. 6 illustrates the touch input device shown in FIG. 4 in an antenna-driven mode (or a stylus-driven mode). 13 is a diagram showing a case where the device operates in a standby mode or a stylus uplink mode.

[0085] 4 and 6, in the antenna driving mode, the control unit 500 controls the antenna driving. A plurality of driving circuits for the sensor unit 100 are electrically connected to the plurality of second patterns 102 of the sensor unit 100. The control unit 500 controls a number of switches SW to control a number of second patterns. The conductive traces coupled to the input 102 can be electrically coupled to multiple drive circuitry. Cut.

[0086] The control unit 500 controls the output from each driving circuit unit connected to the second patterns 102. The drive signal (or the pen drive signal) can be controlled.

[0087] For example, the control unit 500 controls a number of driving circuit units connected to a number of second patterns 102. The first drive circuit is controlled so that a pulse signal of a predetermined frequency is output. The third driving circuit section controls so that no pulse signal is output, and the third driving circuit section controls so that no pulse signal is output. An inverted pulse signal having a phase opposite to that of the pulse signal output from the first driving circuit is output. In this case, the second power supply may be electrically connected to the first driving circuit. A current loop is formed between the turn 102 and the second pattern electrically connected to the third driving circuit unit. The current loop thus formed generates a magnetic field, which draws the sensor unit 100 closer. The stylus pen in contact may be driven resonantly.

[0088] The control unit 500 includes a plurality of driving circuit units electrically connected to the second patterns 102. Any two of the drive circuits are controlled to output opposite pulse signals. Therefore, the control unit 500 can change and set the size and position of the current loop in various ways. For example, the control unit 500 may detect a stylus pen in close proximity to the sensor unit 100. When the position of the stylus pen is detected, the two second patterns around the position of the stylus pen are electrically connected. The driving circuit unit connected to the driving circuit unit may be controlled to output opposite pulse signals. If the position of the stylus pen cannot be detected, the second pattern 102 is selected from among the multiple second patterns 102. The driving circuit parts electrically connected to the two second patterns located on the outermost sides of both sides are connected to each other. It is also possible to control the output of a counter pulse signal.

[0089] The control unit 500 can also form two or more current loops simultaneously. He explains.

[0090] 7(a) to 7(c) show a state in which the control unit 500 controls a number of the second patterns 10 shown in FIG. 2 to explain various methods of applying a pen driving signal for driving a stylus pen. For reference, (a) to (c) of FIG. 7 show one of the first The two patterns 102 are simply shown with one line (Ch), and each line (Ch) is one channel. Become Nell.

[0091] FIG. 7(a) shows a state in which the stylus pen 50 is inserted into the center (end) of the sensor unit 100 shown in FIG. For example, when the signal is located on the fifth channel Ch5, In this case, the control unit 500 may perform the following operation based on the position of the stylus pen 50. The same number of channels (Ch2,Ch3,Ch4 / Ch6,Ch7,Ch8) on both sides A number of drive circuits are controlled so that a pulse signal and an inverted pulse signal (or ground) are applied. Specifically, the control unit 500 is located on the left side of the stylus pen 50. A pulse signal is applied to the three channels Ch2, Ch3, and Ch4. The 6th to 8th channels Ch6,C are located on the right side of the stylus pen 50. It is possible to control the application of an inverted pulse signal to Ch7, Ch8. In (a), the stylus pen 50 is used as a reference and three channels are provided on the left and right. The following is shown, but not limited to, the application of a signal and an inverted pulse signal (or ground). For example, in FIG. 7(a), the stylus pen 50 is used as a reference and two points are located to the left and right. A pulse signal and an inverted pulse signal (or ground) may be applied to one or more channels. Even if a pulse signal and an inverted pulse signal (or ground) are applied to four or more channels, good.

[0092] FIG. 7B shows a state in which the stylus pen 50 is positioned at the end of the sensor unit 100 shown in FIG. For example, when the channel is located between the 0th channel Ch0 and the 1st channel Ch1, Compared to FIG. 7(a), the control unit 500 uses the stylus pen 50 as a reference. Apply a pulse signal and an inverted pulse signal (or ground) to the same number of channels on the left and right In such a case, the control unit 500 may not be able to move the stylus pen 50 to the left. On the right, apply a pulse signal and an inverted pulse signal (or ground) to different numbers of channels. Specifically, a pulse signal can be input to the 0th channel Ch0 and a pulse signal can be input to the 1st channel Ch1. or control the third channel Ch1, Ch2, and Ch3 to apply an inverted pulse signal. Although not shown in the drawing, the stylus pen 50 is located on the left side of the 0th channel Ch0. If it is located on the outermost edge of the It is also possible to control h2 so that an inverted pulse signal is applied to it.

[0093] In Fig. 7(a) and (b), there are many channels (Ch0, Ch1...Ch19). The more the number of channels, the more terminals the control unit 500 needs to have to drive each channel. Therefore, the configuration of the driving circuit section in the control section 500 becomes complicated. ...Ch19) by electrically connecting at least two adjacent channels to form one Specifically, the channel shown in FIG. As mentioned above, the two channels are electrically connected to form one channel. In this configuration, the same signal is applied to the two electrically connected channels at the same time. In Figure 7(c), two of the 20 channels (Ch0, Ch1...Ch19) are added. It is electrically connected to form 10 channels. Three of them are electrically connected together, and the remaining two are electrically connected together to form seven channels. It is also possible to electrically connect four of them together to form five channels.

[0094] FIG. 8 illustrates a touch input device according to the embodiment of the present invention in a stylus sensing mode (or a stylus sensing mode). 13 is a diagram showing a case where the mobile station operates in a multiple downlink mode.

[0095] 4 and 8, in the stylus sensing mode, the control unit 500 A plurality of sensing circuits for the laser sensing are provided on the first pattern 102 and the second pattern 103 of the sensor unit 100. The control unit 500 can be electrically connected to the three patterns 103. A conductive layer connected to a plurality of first patterns 101 and a plurality of third patterns 103 by controlling sw. The conductive traces can be electrically coupled to multiple sensing circuitry.

[0096] The touch input device according to the embodiment of the present invention is configured as follows: In the sensing mode, a number of sensing circuits are arranged according to the position of the stylus pen on the sensor unit 100. The advantage of this is that the output voltage of the part is hardly changed. Please refer to a) through (f) for explanation.

[0097] 9(a) to (f) are schematic diagrams illustrating the operation principle of the stylus sensing mode of FIG. 1 is a diagram for explaining the above.

[0098] FIG. 9(a) shows one of the first patterns 101 shown in FIG. 8 and a FIG. 9( a ) is a schematic model of the sensing circuit of the connected control unit 500. b) is a second pattern 102 disposed inside any one of the first patterns 101 FIG. 1 is a schematic modeled circuit diagram.

[0099] FIG. 9(c) is a voltage distribution graph in the circuit diagram of FIG. 9(a), and FIG. 9(d) is a is a voltage distribution graph in the circuit diagram of FIG. 9(b).

[0100] 9(a) and 9(c), a sensing circuit portion is formed on the first pattern 101. If the stylus pen approaches any point A that is far away, the stylus pen will be placed at that point. The voltage induced by the signal emitted from the amplifier (Vemf, hereafter referred to as the "induced voltage") is occurs.

[0101] If an induced voltage (Vemf) occurs at point A, the first pattern 101 viewed from point A to the left will Since the equivalent capacitance becomes smaller, the equivalent impedance becomes larger. Therefore, The induced voltage (Vemf) is mostly applied to the left side of point A, and the right side of point A is almost 0 (V). The voltage is close to 0V to the right of point A, and almost no current flows. The voltage drops due to the equivalent resistance of the first pattern 101 to the input terminal of the sensing circuit. There is almost no voltage applied to

[0102] Referring to (b) and (d) of FIG. 9, if an induced voltage (Vemf) occurs at point A, The other ends of the second patterns 102 are electrically connected to each other on the left side of point A. Since the equivalent capacitance becomes large, the equivalent impedance approaches 0. Therefore, 0 (V) is applied to the left side of point A, and one end of the second pattern 102 is applied to the right side of point A. Since it is open, no voltage drop occurs at the equivalent resistance, and the voltage remains the same as Vemf It takes time.

[0103] Comparing (c) and (d) of FIG. 9, the first pattern 101 and the second pattern 102 It can be seen that there is a potential difference of Vemf at any position during the The potential difference between the first pattern 101 and the second pattern 102 is about Vemf. Capacitive coupling between the first pattern 101 and the second pattern 102 g) is caused by the capacitive coupling. As a result, a current flows from the second pattern 102 to the first pattern 101. As shown in FIG. 1(a), the position of the stylus pen is far away from the sensing circuit unit of the control unit 500. As the current increases, the current generated by the first pattern 101 itself decreases. Since a current flows from the first pattern 102 to the first pattern 101, the control The current output to the sensing circuit unit 500 is almost the same as the position of the pen. The control unit 500 detects the stylus through a sensing circuit unit electrically connected to the first pattern 101. You can sense the position of the pen.

[0104] As can be seen from (a) to (e) of FIG. 9, point A moves to the left or right. Even if the voltage Vmf is changed, the potential difference between the first pattern 101 and the second pattern 102 remains constant as Vmf. Therefore, the position of the stylus pen on the sensor unit 100 is detected by the sensing circuit. The control unit 500 receives a constant signal output from the sensing circuit unit regardless of whether the sensor is close or far from the sensor unit. The stylus pen can be sensed from the signal.

[0105] On the other hand, in the explanation of FIG. 9(e), the flow from the second pattern 102 to the first pattern 101 It was explained that the current entering the junction is due to capacitive coupling, but this is not the only explanation. For example, the current flowing from the second pattern 102 to the first pattern 101 is This is also possible through inductive coupling (magnetic field coupling).

[0106] FIG. 10 is a schematic diagram of a touch input device according to another embodiment of the present invention.

[0120] The 2b pattern 102b includes an inverted triangular pattern portion, a triangular pattern portion, and an inverted triangular pattern portion. The connecting pattern portion may include a connecting pattern portion connecting the connecting portion and the triangular pattern portion.

[0121] The multiple 1a patterns 101a and the multiple 1b patterns 101b intersect along a first direction. The multiple 1a patterns 101a are electrically connected to each other, and the multiple 1b patterns The patterns 101b are also electrically connected to each other.

[0122] The 1a pattern 101a located at one end of the multiple 1a patterns 101a is a control pattern. 500' and is electrically connected to the second portion 500'.

[0123] The 1b pattern 101b located at one end of the multiple 1b patterns 101b is a control pattern. 500' and is electrically connected to the second portion 500'.

The plurality of 2a patterns 102a and the plurality of 2 The second b pattern 102b located at one end of the b pattern 102b is electrically connected to the control unit 500. The second pattern 102a located at the other end is directly connected to the adjacent second pattern 102a. Here, the second pattern 102a located at the other end and the adjacent second pattern 102b may be electrically connected to each other. The second pattern a may be grounded.

[0126] The control unit 500' has the same functions as the control unit 500 shown in FIG.

[0127] FIG. 11 shows the touch input device shown in FIG. 10 in touch sensing mode (or 2D sensing mode). 13 is a diagram showing the case where the device operates in a sensing mode.

[0128] 10 and 11, in the touch sensing mode, the control unit 500′ A driving circuit for sensing is electrically connected to the third pattern 103 of the sensor part 100'. Each of the third patterns 103 can be electrically connected to one driving circuit unit. They may be linked.

[0129] In addition, the control unit 500' controls a sensing circuit unit for touch sensing in the sensor unit 100'. The 1a and 1b patterns 101a and 101b may be electrically connected.

[0130] In the touch sensing mode, the control unit 500' detects a touch on a number of the third patterns 103. A driving signal for sensing is applied to the plurality of 1a and 1b patterns 101a, 101b. 1. A plurality of 1a and 1b patterns 101a, 101b are received. The detection circuit unit of the control unit 500' electrically connected to the detection signal 101b detects the detection signal included in the detection signal.

By subtracting the sensed signal received from 1b, the display noise and LGM noise are eliminated. This can offset the disadvantages.

[0131] Here, the capacitive coupling between the third pattern 103 and the fourth pattern 104 In order to prevent capacitive coupling from occurring, the control unit 500' has a number of third patterns. The same driving signal is applied to the first pattern 103 and the second pattern 104. Alternatively, the control unit 500' may control the fourth patterns 104 to be applied with a reference potential. It is also possible to control it as follows.

[0132] FIG. 12 illustrates the touch input device shown in FIG. 10 in an antenna drive mode (or a stylus drive mode). 13 is a diagram showing a case where the device is operated in a drive mode or a stylus uplink mode.

[0133] 10 and 12, in the antenna driving mode, the control unit 500' controls the antenna The driving circuit unit for driving the sensor unit 100' is disposed on the second a and second b patterns 102a, 102b. 2b.

[0134] The control unit 500' is connected to a number of 2a and 2b patterns 102a and 102b. The control unit 500' can control the drive signals output from each drive circuit unit. controls the first drive circuit unit to output a pulse signal of a predetermined frequency, and the second drive circuit unit The third drive circuit is controlled so that no pulse signal is output from the first drive circuit. The control circuit outputs a pulse signal that is opposite to the pulse signal output from the drive circuit. In this case, the second a and second b patterns electrically connected to the first driving circuit unit 102a, 102b and the third driving circuit unit are electrically connected to the second a and second b patterns. A current loop is formed. A magnetic field is generated by the current loop, and the magnetic field The stylus pen in contact may be resonated and driven.

[0135] The control unit 500' is electrically connected to the multiple 2a and 2b patterns 102a and 102b. Among the many drive circuits connected to the same circuit, two of the drive circuits are sent with mutually opposing pulse signals. Therefore, the control unit 500' can control the current loop For example, the control unit 500' may be located adjacent to the When the position of the stylus pen is detected, two second patterns around the position of the stylus pen are The driving circuit unit electrically connected to the ring outputs opposite pulse signals. If the position of the stylus pen cannot be detected, a large number of second a and The two 2a and 2b patterns 102a and 102b located on the outermost sides of both sides are The driving circuitry electrically connected to the b patterns 102a and 102b is provided with opposing pulses. It is also possible to control the output of a signal.

[0136] Meanwhile, although not shown in a separate drawing, the control unit 500' has a number of 1a patterns 101 a, 1b pattern 101b, or 3rd pattern 103. In this case, there is an advantage that the total number of channels can be reduced.

[0137] FIG. 13 shows the touch input device shown in FIG. 10 in a stylus sensing mode (or a stylus sensing mode). 13 is a diagram showing the case where the TIRUS operates in downlink mode.

[0138] 10 and 13, in the stylus sensing mode, the controller 500′ The sensing circuit unit for stylus sensing is provided on the first a and first b patterns of the sensor unit 100'. The first and second patterns 101a, 101b and 103 may be electrically connected to the first and second patterns 101a, 101b and 103, respectively. do.

[0139] In the stylus sensing mode, the sensor part If a stylus pen approaches any position on the 100', a predetermined signal is generated from the stylus pen. The output signal is used to control the 1a, 1b, 2a, 2b, 3, and 4 patterns. Induced voltages are generated in the electrodes 101a, 101b, 102a, 102b, 103, and 104.

[0140] Here, if the stylus pen is located far away from the control unit 500', the induced Due to the generation of the voltage, almost no current flows through the many 1a patterns 101a themselves, but Since current flows from multiple 2a patterns 102a, the control unit 500' is The position of the stylus pen is detected through a sensing circuit unit electrically connected to the turn 101a. Here, a current flows from the 2a pattern 102a to the 1a pattern 101a. The induced voltage flows between the 1a pattern 101a and the 2a pattern 102a. A potential difference of about 101a occurs, and the 1a pattern 101a and the 2a pattern This is due to capacitive coupling between 102a and 102b.

[0141] Similarly, almost no current flows through the numerous 1b patterns 101b themselves, but the numerous 2b Since the current flows in from the pattern 102b, the control unit 500' controls a number of 1b patterns 1 01b, and a position of the stylus pen can be detected through a sensing circuit electrically connected to the sensor. can.

[0142] Similarly, almost no current flows through the third pattern 103 itself, but the current flows through the fourth pattern 104. Since the current flows from the third pattern 103, the control unit 500' is electrically connected to the third pattern 103. The position of the stylus pen can be detected via the sensing circuit unit.

[0143] Meanwhile, although not shown in the drawing, unlike FIG. 13, the control unit 500' has multiple sensing circuits. The number of 2a patterns 102a, 2b patterns 102b, or 4th patterns 104 It is also possible to electrically couple the sensor to detect the position of a stylus pen.

[0144] FIG. 14 is a schematic diagram of a touch input device according to yet another embodiment of the present invention.

[0145] The sensor unit 100 ″ of the touch input device shown in FIG. 14 is the same as the sensor unit shown in FIG. Compared with 100'', the structures of patterns 1a, 1b, 2a, 2b, 3 and 4 are The difference is that the first pattern is a number of first b patterns electrically connected to each other along the first direction. The 1b pattern located on one side (lower side) of the pattern 101b is connected to the conductive trace. A plurality of control units 500 ″ are electrically connected to each other along a first direction. Among the 1a patterns 101a, the 1a pattern 101a located on the other side (upper side) is controlled. 5. The point is that the control unit 500 is electrically connected to the control unit 500'' via a conductive trace.

[0146] FIG. 15 shows the touch input device shown in FIG. 14 in touch sensing mode (or 2D sensing mode). 13 is a diagram showing the case where the device operates in a sensing mode.

[0147] The explanation of the touch sensing mode is the same as that explained in FIG. 11, so it will be omitted.

[0148] FIG. 16 illustrates the touch input device shown in FIG. 14 in an antenna drive mode (or a stylus drive mode). 13 is a diagram showing a case where the device is operated in a drive mode or a stylus uplink mode.

[0149] The explanation of the antenna driving mode is the same as that explained in FIG. 12, and therefore will be omitted.

[0150] FIG. 17 shows the touch input device shown in FIG. 14 in a stylus sensing mode (or a stylus sensing mode). 13 is a diagram showing the case where the TIRUS operates in downlink mode.

[0151] The stylus sensing mode in Figure 17 is compared with the stylus sensing mode in Figure 15. There are differences.

[0152] The stylus pen is driven after approaching an arbitrary position on the sensor unit 100''. When a signal is emitted from the stylus pen, a specific signal is output from the stylus pen. The first pattern 101a, the first pattern 101b, the second pattern 101a, the second pattern 101b, the third pattern 101b, and the fourth pattern 101a are generated by the signal. Induced voltages are generated at b, 102a, 102b, 103, and 104.

[0153] Here, if the stylus pen is located far away from the control unit 500', the induced Due to the generation of the voltage, almost no current flows through the many 1b patterns 101b themselves, but Current flows in not only from the multiple 2b patterns 102b but also from the multiple 1a patterns 101a. Therefore, the control unit 500' includes a sensing element electrically connected to a plurality of first patterns 101b. The position of the stylus pen can be detected through the circuit section. The reason why a current flows from the pattern 102b and the pattern 1a 101a to the pattern 1b 101b is that Between the 1b pattern 101b and the 2b pattern 102b, and between the 1b pattern 101 A potential difference of the induced voltage is generated between the pattern 1a and the pattern 1b. The capacitive coupling between the first pattern 101b and the second pattern 102b due to the difference Pulling, and the capacitance between the 1b pattern 101b and the 1a pattern 101a This is due to reactive coupling.

[0154] Here, the reason why a current flows from the 1a pattern 101a to the 1b pattern 101b is Unlike FIG. 13, a relatively large current flows through the multiple 1a patterns 101a themselves. This is because the direction of the conductive traces connected to the multiple 1a patterns 101a 1b pattern 101b is connected in a direction opposite to the conductive trace direction connected to the plurality of 1b patterns 101b. In other words, the stylus pen is connected to a number of 1b patterns 101b. When the stylus pen is located far away from the sensing circuit unit, the stylus pen detects a large number of 1a patterns 1 This is because the sensing circuit unit connected to 01a is located closer to the sensor circuit unit.

[0155] Similarly, almost no current flows through the third pattern 103 itself, but the current flows through the fourth pattern 104. As the current flows in, the control unit 500' detects the sensing element electrically connected to the third pattern 103. The position of the stylus pen can be detected via the circuit section.

[0156] Meanwhile, although not shown in the drawing, unlike FIG. 17, the control unit 500'' has multiple sensing circuit units. The number of 2a patterns 102a, 2b patterns 102b, or 4th patterns 104 An electrical connection can also be made to detect the position of a stylus pen.

The mutual capacitance Cm between the turn portion 103' and the fourth pattern portion 104' is improved. The higher the mutual capacitance Cm, the higher the stylus sensitivity. In the sensing mode, the voltage value output from the sensing circuit unit of the control unit 500 can be increased. Therefore, the stylus sensing sensitivity can be improved.

[0195] Here, the modified example shown in FIG. 21 can be applied to FIG. 19 and FIG. 20 as it is. Cut.

[0196] FIG. 22 shows yet another modified example of the sensor unit 100 shown in FIG.

[0197] The sensor unit 100″ shown in FIG. 22 has the following features as compared with the sensor unit 100 shown in FIG. It further includes a number of fifth pattern portions 105 and a number of sixth pattern portions 106 .

[0198] The fifth patterns 105 are formed in the same layer (2 nd layer) The electrodes are arranged in a large number along the first and second directions.

[0199] Each fifth pattern 105 is formed on the other layer (1 st The third pattern 103 arranged in the The fifth pattern 105 includes a shape that corresponds to and overlaps with a part of the other pattern portion. Layer (1 st The fourth pattern 104 is electrically connected to the second pattern 105 through a via. .

[0200] The fifth patterns 105 and the third patterns 103 are mutually connected in a vertical direction. In addition, the fifth pattern 105 can form a capacitance Cm within the third pattern 103. Since the third pattern 103 is electrically connected to the fourth pattern 104 of the portion, the third pattern 103 is The mutual capacitance Cm can be formed not only with the turn 104 but also with the fifth pattern 105. It becomes like this.

[0203] The sixth pattern portions 106 and the first pattern portions 101 are mutually capacitive in a vertical direction. The sixth pattern portion 106 can form a chest of drawers Cm. Since the first pattern 101 is electrically connected to the second pattern 102 inside the first pattern 101, the first pattern 101 is A mutual capacitance Cm can be formed not only between the second pattern 102 but also between the sixth pattern 105. It becomes possible.

[0204] In this way, the sensor unit 100″ shown in FIG. In addition, a mutual capacitance in the vertical direction can be formed. 03 can form mutual capacitance not only in the horizontal direction but also in the vertical direction. Therefore, in the stylus sensing mode, the sensing circuit of the control unit 500 This increases the voltage output from the sensor, improving the sensitivity of the stylus. This can be done.

[0205] FIG. 23 shows yet another modified example of the sensor unit 100 in FIG.

[0206] The sensor unit 100''' shown in FIG. 23 has the following features in comparison with the sensor unit 100 shown in FIG. In other words, a part of the second pattern 102′ is disposed in a layer different from the remaining part of the second pattern 102′. The second pattern 102' is a plurality of main pattern portions and a plurality of main pattern portions. The second pattern includes a connecting pattern portion connecting two adjacent main pattern portions. The multiple main pattern portions of the second pattern 102' are connected to the multiple connecting pattern portions of the second pattern 102'.

The third pattern 103 and the fourth pattern 104 are disposed in the same layer, and the second pattern 102' The multiple connecting pattern portions are disposed in the same layer as the first pattern 101, similarly to FIG.

[0207] The sensor unit 100''' shown in FIG. 23 is similar to the sensor unit 100 shown in FIG. The control unit 500 controls the touch sensing mode, antenna driving mode, stylus pen driving mode, The optical fiber may be driven in a single mode.

[0208] FIG. 24 shows yet another modified example of the sensor unit 100 in FIG.

[0209] The sensor unit 100'''' shown in FIG. 24 is the same as the sensor unit 100''' shown in FIG. In comparison, a part of the fourth pattern 104' is disposed in a layer different from the remaining part. Specifically, the fourth pattern 104' includes a plurality of main pattern portions and a plurality of main pattern portions. a connecting pattern portion connecting two adjacent main pattern portions among the main pattern portions, The multiple main pattern portions of the fourth pattern 104' are connected to multiple connecting portions of the fourth pattern 104'. The fourth pattern 104' is disposed in a layer different from the pattern portion. The connecting portion is disposed on the same layer as the first pattern 101, and a large number of connecting patterns of the fourth pattern 104' are The loop portion is the same as a number of main pattern portions of the second pattern 102′ and the third pattern 103. are arranged in layers.

[0210] To summarize, in the sensor unit 100'''' shown in FIG. , a number of connecting pattern portions of the second pattern 102', a number of main The pattern portion is disposed on the first layer, and a large number of connected third patterns 103 and fourth patterns 104' are arranged. A connecting pattern portion, multiple main pattern portions of the second pattern 102' are disposed on the second layer. Here, the first layer and the second layer are different layers, and the positional relationship is different in one layer. may be disposed on one of the

[0211] The sensor unit 100'''' shown in FIG. 24 is similar to the sensor unit 100 shown in FIG. The control unit 500 controls the touch sensing mode, the antenna driving mode, the stylus pen It may be driven in a sensing mode.

[0212] FIG. 25 shows yet another modified example of the sensor unit 100 shown in FIG.

[0213] The sensor unit 100'''' shown in FIG. 25 is the same as the sensor unit 100'' shown in FIG. 24. In comparison with the sensor unit 100'''' shown in FIG. The sensor unit 100'''' shown in FIG. 25 includes a second pattern 102'' and a fourth pattern 103''. 04'' is different.

[0214] Specifically, the second pattern 102'' includes a number of main pattern portions 102a'' and a number of Although the connecting pattern portion 102b' is included, the size of the main pattern portion 102a'' is the same as that of FIG. The main pattern portion of the second pattern 102' of the sensor portion 100'''' shown The size of the main pattern portion 102a'' is larger than that of the first pattern 101. It may have a size and shape corresponding to the main pattern portion.

[0215] Also, the fourth pattern 104'' has a number of main pattern portions 104a'' and a number of connecting portions. The size of the main pattern portion 104a'' is different from that shown in FIG. The fourth pattern 104' of the sensor portion 100'''' is larger than the main pattern portion. The size of main pattern portion 104a'' is equal to that of the main pattern portion 104a of third pattern 103. The conductive pattern portion may have a size and shape corresponding to the conductive pattern portion.

[0216] The main pattern portion 102a'' of the second pattern 102'' corresponds to the second pattern 1 in FIG. Since the main pattern portion of the first pattern 101 is larger than the main pattern portion of the second pattern 102, The corresponding area of ​​the second pattern 102'' is increased, and the mutual capacitance between the second pattern 102'' and the first pattern 101 is reduced. Therefore, the stylus sensing model can be used with a higher passivity Cm. This can further improve stylus sensing sensitivity when loading.

[0217] Also, the main pattern portion 104a'' of the fourth pattern 104'' is the fourth pattern shown in FIG. Since the third pattern 104' has a larger size than the main pattern portion of the third pattern 104', 03, the corresponding area is widened, and the interaction between the fourth pattern 104'' and the third pattern 104 is The capacitance Cm can be further improved. Therefore, the stylus sensing Stylus sensing sensitivity can be further improved when in touch mode.

[0218] FIG. 26 is a diagram showing a modified example of the sensor unit 100 shown in FIG.

[0219] The sensor unit 100'''''' shown in FIG. 26 is different from the sensor unit 100 shown in FIG. In comparison, the other ends of the multiple second patterns 102 and the other ends of the multiple fourth patterns 104 are are electrically connected.
