As a result, touch screens are increasingly being used to operate computing systems. Recently, a stylus pen is additionally used when operating the touch input device. It is possible.

[0003] FIG. 1 shows a conventional touch input device with a flexible display panel. The output voltage Vout of the CVA (Capacitance to Voltage Amplifier) ​​varies depending on the position of the Raspen 10. 1 is a schematic diagram for explaining the change.

[0004] Referring to FIG. 1, the position of the pen 10 on the flexible display panel determines the output of the CVA. The reason for the different forces is the impedance on both sides of the sensing line centered on the pen 10. The reason is that the impedance ratio changes.

[0005] Metal mesh based on the long axis of conventional flexible display panels The resistance R of the touch sensor is about 1.2 kΩ (ohm), and the capacitor C is about 250 pF.

[0006] Based on the 10-distributed model, the capacitor (c The impedance of the apacitor is about 200 times that of the resistor (120 (ohm) vs. 1 / (2π*300k*25pF)=21k (ohm)), so the capacitor is the main culprit.

[0007] FIG. 2 shows the output voltages Vout1 and Vout2 of the CVA, which differ depending on the position of the pen 10 in FIG. This is a diagram for explaining the above through current sensing. In Figure 1, the output voltages Vout1 and Vout2 of the CVA differ depending on the position of the pen 10. 1 is a diagram for explaining through voltage sensing.

[0008] 2 and 3, the output voltage of the CVA varies depending 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 larger the output voltage of the CVA is. The output voltage of the CVA decreases as it moves away from the sensing circuit unit 50 side. Summary of the Invention [Problem to be solved by the invention]

It outputs a signal emitted from the stylus pen and detects the signal emitted from the stylus pen located on the screen. The position of the antenna can be detected.

[0034] Various embodiments will now be described in detail with reference to the accompanying drawings.

[0035] FIG. 4 is a schematic diagram of a sensor unit 100 of a touch input device according to a first embodiment of the present invention. 5 shows a sensor unit 100' according to a modification of the sensor unit 100 shown in FIG.

[0036] The touch input device according to the first embodiment of the present invention is a portrait type touch input device. Such a portrait-type touch input device may be a wide, high-resolution touch input device. The control unit (not shown) that controls the sensor unit 100 is located below the sensor unit 100. For example, it can be made to fit the shape of a smartphone.

[0037] The sensor unit 100 can only detect the position of an object such as a finger placed on the screen. It can drive the stylus pen positioned on the screen without releasing the It can detect the position of the stylus pen on the screen by detecting the signal emitted. .

[0038] The sensor unit 100 includes a large number of patterns (or a large number of electrodes).

[0039] The sensor unit 100 may include a number of first to fourth patterns 101, 102, 103, and 104.

[0040] The first pattern 101 has a shape extending along an arbitrary first direction y. The first pattern 101 may be in the long axis direction of the screen of the input device. It is okay to do so.

[0041] Two conductive patterns may be connected to the first pattern 101. , which becomes the electrical path of the first touch sensing receiving channel FRX_E, and the other one conductive pattern The second touch sensing receive channel FRX_O may be electrically connected to the first touch sensing receive channel FRX_O. The pattern is electrically connected to the first odd pattern included in the first pattern 101 and is connected to the other one The conductive pattern is electrically connected to the first even pattern included in the first pattern 101. The first odd pattern and the first even pattern are as described in FIGS. 8 to 16. Meanwhile, the two conductive patterns are the electrical paths of the stylus sensing channel SRX. It may be.

[0042] The second pattern 102 has a shape extending along the first direction y and is disposed adjacent to the first pattern 101. The second pattern 102 is placed at a predetermined distance from the first pattern 101. TX).

[0043] The third pattern 103 has a shape extending along a second direction x that is different from the first direction. may be a direction perpendicular to the first direction y and may be a direction of the minor axis of the screen of the touch input device. The third pattern 103 may also be named ARX (Active RX).

[0044] The fourth pattern 104 has a shape extending along the second direction x and is disposed adjacent to the third pattern 103. The fourth pattern 104 is placed at a predetermined distance from the third pattern 103. RX).

[0045] The third and fourth patterns 103 and 104 are disposed on the first and second patterns 101 and 102. The second patterns 101 and 102 are spaced apart from each other by a predetermined distance. However, the first to fourth patterns may be arranged on the same layer.

[0046] The plurality of first patterns 101 are arranged along the second direction x, and the plurality of second patterns 102 are also arranged along the second direction x. The plurality of third patterns 103 are arranged along the first direction y, and the plurality of fourth patterns The turns 104 are also arranged along the first direction y.

[0047] The first pattern 101 extends along a first direction y, the third pattern 103 extends along a second direction x, and the third pattern 104 extends along a second direction x. Since the one direction y is longer than the second direction x, the number of the multiple first patterns 101 is smaller than the number of the multiple third patterns 103. Therefore, the number of channels of the first patterns 101 is smaller than the number of channels of the first patterns 101. The number of channels is less than that of the third pattern 103.

[0048] Here, the number of the first patterns 101 and the number of the third patterns 103 are determined based on the number of the touch input device. It may be increased or decreased depending on the size of the screen of the device.

[0049] The number of second patterns 102 may be the same as the number of first patterns 101. The other ends of the second patterns 102 are electrically connected to each other via a conductive pattern 102m. Here, the conductive pattern 102m is a metal mesh or a silver trace ( Silver Trace).

[0050] One end of each of the plurality of second patterns 102 is individually connected to one conductive pattern. Here, one end of each of the plurality of second patterns 102 is individually connected to form a conductive pattern. The line may be the electrical path of one stylus drive channel STX.

[0051] Meanwhile, as shown in FIG. 5, two or more adjacent second patterns 102 are formed. One end of the pattern 102 may be electrically connected via a conductive pattern. As a result, the number of channels in the multiple second patterns 102 is half the number of channels in the multiple first patterns 101. can be reduced to

[0052] Referring again to FIG. 4, since a large number of third patterns 103 are arranged along the first direction y, The number of the third patterns 103 is greater than the number of the first patterns 101. The number of channels in the third pattern 103 is greater than the number of channels in the first pattern 101.

[0053] One end of each of the third patterns 103 may be connected to one conductive pattern. The conductive patterns connected to one end of each of the third patterns 103 are used for touch sensing. Electrical path of the driving channel FTX and / or electrical path of the stylus sensing channel SRX Here, taking into consideration the width of the left and right bezels of the touch input device, a large number of third patterns may be Half of the electrodes 103 have a conductive pattern connected to the right end, and the other half have a conductive pattern connected to the left end. The turns may be interlocked.

[0054] The number of fourth patterns 104 may be the same as the number of third patterns 103. The other ends of the fourth patterns 104 are electrically connected to each other via conductive patterns 104ml and 104mr. Here, the conductive patterns 104ml and 104mr are half of the fourth patterns 104. The left conductive pattern 104ml connecting the left end of the fourth pattern 104 and the remaining half of the fourth pattern The left conductive pattern 104mr may include a right conductive pattern 104mr connecting the right ends of the left conductive pattern 104mr. The right conductive pattern 104mr is a conductive pattern connected to a number of third patterns 103. They may be arranged so as not to overlap or cross each other.

[0055] In the sensor unit 100 of the touch input device shown in FIG. 4, a plurality of first patterns 1 01 and a number of third patterns 103 are basically used to sense the touch of an object such as a finger. To this end, the first patterns 101 are formed as touch driving electrodes to which touch driving signals are applied. and the third pattern 103 is a touch sensing electrode (or , touch receiving electrode). Of course, it can also work the other way around. .

[0056] The sensor unit 100 of the touch input device shown in FIG. 4 drives and senses the stylus pen. In order to perform sensing, a number of first to fourth patterns 101, 102, 103, and 104 are provided. Various combinations may be used. Various combinations are shown in below. In Table 1 below, "1" indicates a number of first patterns 101, and "2" indicates a number of second patterns 102. , "3" indicates a large number of third patterns 103, and "4" indicates a large number of fourth patterns 104.

[0057] [Table 1]

[0058] Referring to Table 1 above, in various combinations (No. 1 to No. 32), many first The pattern 101 and the multiple third patterns 103 are used to sense the touch of an object such as a finger. Specifically, the third patterns 103 act as touch driving electrodes, and the first patterns 104 act as touch driving electrodes. The turn 101 acts as a touch receiving electrode.

[0059] One or two of the first to fourth patterns 101, 102, 103, and 104 are It can operate with a stylus driving electrode for driving the pen. Use one or two of the patterns 101, 102, 103, and 104 to drive the stylus pen. The X-axis drive can form a current loop for driving a number of first patterns 101. and any one of the plurality of second patterns 102, and the Y-axis drive is a plurality of third patterns 103 and a plurality of The stylus pen may be driven in either one of the fourth patterns 104. The stylus pen may be driven in the X-axis and Y-axis. Either one of these movements is possible, or both are possible.

[0060] Two of the first to fourth patterns 101, 102, 103, and 104 are input from a stylus pen. It can operate with sensing electrodes that sense emitted stylus signals. To sense the stylus pen signal, both X-axis sensing and Y-axis sensing are required. Therefore, two patterns among the first to fourth patterns 101, 102, 103, and 104 are The X-axis sensing is performed by sensing either one of the multiple first patterns 101 and multiple second patterns 102. The Y-axis sensing may be one of a number of third patterns 103 and a number of fourth patterns 104. It can be either one.

[0061] In the above table 1, "uplink signal strength" refers to the strength of the stylus pen. The same stylus pen drive signal is used for multiple The first pattern 101 and the second pattern 102 are respectively applied and received by the stylus pen. When comparing the magnitude of the signals, it is clear that the stylus pen driving signals are printed on a large number of second patterns 102. When the stylus pen driving signal is applied to a large number of first patterns 101, the number of times the stylus pen driving signal is applied increases. The flash signal is relatively larger.

[0062] The other ends of the second patterns 102 are electrically connected to each other, and the stylus pen By appropriately selecting two or more second patterns to which the drive signal is applied, at least one current loop can be generated. The other ends of the first patterns 101 are electrically connected to each other. When a current flows through each first pattern 101, As the RC of the first pattern 101 is charged, the current flows from one end of each first pattern 101 to the other end. In addition, the current applied through the first patterns 101 is not as good as the current applied through the first patterns 101. The drive signal is transmitted through a number of second amplifiers, which form current loops via capacitive coupling. The signal is transmitted to the pattern 101, but at this time, the signal is attenuated by capacitive coupling. This is because

[0063] Similarly, when the stylus pen drive signal is applied to a number of fourth patterns 104, When the stylus pen driving signal is applied to the third pattern 103, the uplink signal is relatively Even bigger.

[0064] In the above table, "downlink signal strength" refers to the strength of the downlink signal from the stylus pen. It means the magnitude of the received stylus signal. The signal strengths are compared by receiving the signal through the first pattern 101 and the second pattern 102. When the stylus pen signal is received through a plurality of second patterns 102, When the stylus pen signal is received via the first pattern 101, the downlink signal is The reason is that the other ends of the second patterns 102 are electrically connected. The other ends of the first patterns 101 are electrically connected to each other. In particular, there are many cases where current loops are formed through capacitive coupling. Since the stylus pen signal is transmitted from the second pattern 101 to a number of first patterns 101, This is because attenuation of the downlink signal occurs when

[0065] Similarly, when the stylus pen signal is received via a number of fourth patterns 104, When the stylus pen signal is received via the third pattern 103, the downlink signal is Even larger in size.

[0066] In the above table, "Stylus additional channel" refers to the touch sensing This means that you must configure an additional channel for the stylus pen. For driving or sensing a stylus pen, a number of second patterns 102 and / or a number of fourth patterns 103 are provided. When using pattern 104, an additional channel is required (shown as "Yes" in Table 1). On the other hand, the driving and sensing of the stylus pen requires a large number of first panels for touch sensing. When using pattern 101 or / and pattern 3 103, no additional channel is required (see Table 1). (If there is no such information, it is displayed as "none").

[0067] Below are some examples of the various combinations (No. 1 to No. 32) in Table 1 above. Combinations not described here will be apparent to those skilled in the art from the following detailed description. If so, that would be understandable.

Because it is used as a tiger sensing electrode, the magnitude of the downlink signal is relatively small. In addition, since a large number of second patterns 102 are separately used as stylus driving electrodes, An additional channel is required for driving the stylus pen. No additional channels are required.

The second patterns 102 are separately used as stylus sensing electrodes, and the fourth patterns 101 are 04 is used separately as a stylus driving electrode and a stylus sensing electrode, Therefore, an additional channel is required for driving and sensing the sensor.

The fourth pattern 104 is used separately as a stylus driving electrode and a stylus sensing electrode. Since it is used separately as a pole, it requires an additional channel for driving and sensing the stylus pen. A rule is necessary.

The other ends of the fourth patterns 104a may be electrically connected to each other. If the fourth pattern 104a is connected to the fourth pattern 104b, the total impedance is reduced because each fourth pattern 104a adds a different capacitance. This may have a similar effect to when the other ends of the many fourth patterns 104a are grounded. .

[0112] The third pattern 103a and the fourth pattern 104a may be arranged on the same layer. In this way, the third pattern 103a and the fourth pattern 104a can be formed in the same layer.

[0116] The multiple sensing circuits are divided into a sensing circuit for touch sensing and a sensing circuit for stylus sensing. Here, some of the multiple sensing circuits may include a sensing circuit for detecting the temperature. It can also perform touch sensing and stylus sensing.

[0117] The control unit 500 controls the sensor unit 100a in a touch drive / sensing mode, an antenna drive mode, and It can be controlled to operate in either one of the following modes: can.

[0118] The control unit 500 electrically connects a number of driving / sensing circuits to the sensor unit 100a according to each mode. For this purpose, the control unit 500 controls a number of driving / sensing circuit units and the sensor unit 100a. The power supply may include a number of switches for electrically connecting the power supplies.

[0119] 9 to 11 show that the sensor unit 100a shown in FIG. 8 was used as No. 1 in Table 1 above. 1 is a diagram for explanation.

[0120] FIG. 9 illustrates the touch input device shown in FIG. 8 in touch drive / sensing mode (or 2D sensor mode). 10 shows the touch input mode shown in FIG. 8. The device is in antenna-driven mode (or stylus-driven mode, or stylus uplink mode). 11 is a diagram showing the touch input device shown in FIG. 8 in a touch mode. When operating in stylus sensing mode (or stylus downlink mode) 1 is a drawing showing the above.

[0121] Referring to FIG. 9, in the touch driving / sensing mode, the control unit 500 The driving circuit unit can be electrically connected to the third pattern 103a of the sensor unit 100a. One driving circuit unit may be electrically connected to each of the third patterns 103a.

[0122] The control unit 500 controls the sensing circuit unit for touch sensing to correspond to a plurality of first patterns of the sensor unit 100a. The plurality of electrodes 101a and 101b arranged along the first direction may be electrically connected to the electrodes 101a. The first pattern 101a has a first odd pattern 101o and a second even pattern 101e. The first odd-numbered patterns 101o are arranged along the first direction, and the second odd-numbered patterns 101o are arranged along the first direction. The even-numbered patterns 101e are electrically connected to each other.

[0123] The control unit 500 applies a driving signal for touch driving to a predetermined third pattern 103a, and Two signals received from the first odd pattern 101o and the second even pattern 101e arranged along the direction The sensing circuit unit of the control unit 500 receives the two sensing signals. The control unit 500 can output the capacitance change information as a predetermined voltage value. The voltage values ​​thus obtained can be processed to detect the touch position.

[0124] The control unit 500 receives signals from a plurality of first odd patterns 101o arranged along a first direction. The first sensing signal and the second sensing signal received from the first even-numbered patterns 101e arranged along the first direction. Canceling display noise and LGM noise by subtracting the sensed signals from each other Here, when the driving signal is sequentially applied to the third patterns 103a, If the applied third pattern 103a is immediately adjacent to the first odd pattern 101o, the control unit 500 The second sensing signal can be subtracted from the first sensing signal, and a third pattern to which a driving signal is applied is If the pattern 103a is immediately adjacent to the second even pattern 101e, the control unit 500 determines whether the first sensing signal is a first even pattern or not from the second sensing signal. The signal can be subtracted.

[0125] Capacitive coupling between the third pattern 103a and the fourth pattern 104a In order to prevent the occurrence of the coupling, the control unit 500 controls the number of third patterns to be connected to the number of fourth patterns 104a. Alternatively, the control unit 50 may control the same drive signal as that of the band 103a. 0 can also be controlled so that the reference potential is applied to a number of fourth patterns 104.

[0126] Referring to FIG. 10, in the antenna driving mode, the control unit 500 controls the driving circuit for driving the antenna. The circuit portion may be electrically connected to the second patterns 102a of the sensor portion 100a.

[0127] The control unit 500 controls the antennas output from the respective driving circuits connected to the second patterns 102a. For example, the control unit 500 controls the first drive circuit unit to have a predetermined frequency. The second driving circuit controls the output of a pulse signal of any frequency. The third driving circuit section controls the pulse output from the first driving circuit section so that the In this case, the first drive At least one second pattern 102a electrically connected to the driving circuit unit and a third driving circuit unit are electrically connected to the driving circuit unit. A current loop is formed in at least one second pattern electrically connected to the first pattern. The current loop generates a magnetic field, which resonates and drives the nearby stylus pen. It may be moved.

[0128] The control unit 500 controls the driving circuits electrically connected to the second patterns 102a. Controlling two or more arbitrary drive circuit sections so that mutually opposing pulse signals are output. Therefore, the control unit 500 can change and set the size and position of the current loop in various ways. For example, when the control unit 500 detects the position of a nearby stylus pen, The driving element is electrically connected to at least two second patterns around the position of the stylus pen. The circuitry can be controlled to output opposing pulse signals, If the position of the pen cannot be detected, the pen is located at the outermost edge of the second patterns 102a on both sides. The driving circuit unit electrically connected to the two second patterns 102a outputs opposite pulse signals. It is also possible to control the output of a signal.

[0129] Referring to FIG. 11, in the stylus sensing mode, the control unit 500 The sensing circuit for sensing is formed by a plurality of first patterns 101a and a plurality of third patterns of the sensor part 100a. 103a and 103b, respectively.

[0130] In the stylus sensing mode, a stylus pen is placed at an arbitrary position on the sensor unit 100a. When the stylus pen approaches the first pattern 101a, the first pattern 101a is generated by a pen signal output from the stylus pen. and a part of the first patterns 101a located around the stylus pen among the plurality of third patterns 103a. When this occurs, an induced current is generated in a part of the third pattern 103a.

[0131] The reason why a predetermined induced voltage occurs in a part of the first pattern 101a located around the stylus pen is as follows. The reason is that when a stylus pen approaches, a pen signal is emitted from the stylus pen. The electromagnetic induction phenomenon occurs due to the second pattern 102a located around the stylus pen. This is because a large number of second patterns 102a form a current loop. The capacitance between the first pattern 101a and the second pattern 102a is By the coupling, the induced current flowing in the second pattern 102a is The current flows to a part of the first pattern 101a immediately adjacent to 102a, and the induced voltage occurs.

[0132] Similarly, a predetermined induced voltage is generated in a part of the third pattern 103a located around the stylus pen. The reason for this is that when the stylus pen comes close to the object, the particles are released from the stylus pen. Due to the electromagnetic induction phenomenon caused by the pen signal, some of the fourth patterns located around the stylus pen may This is because the many fourth patterns 104a form a current loop. This is due to the formation of a gap between the third pattern 103a and the fourth pattern 104a. By passive coupling, the induced current flowing in a part of the fourth pattern 104a is The flow then moves to a part of the third pattern 103a immediately adjacent to the pattern 104a, and the flow A conduction voltage is generated.

[0133] The control unit 500 controls the induced voltage to flow through a part of the first pattern 101a and a part of the third pattern 103a. The position of the stylus pen can be detected by sensing the first pattern 101. a includes a first odd pattern 101o and a first even pattern 101e, but the control unit 500 The first sensing signal received from the first even number pattern 101o and the first sensing signal received from the first even number pattern 101e are The second sensing signals can be summed to detect the position of the stylus pen.

[0134] 9 to 11, the object is detected by the sensor unit 100a of FIG. 8 using the method No. 1 in Table 1 above. It senses the touch position of the device and indicates that the stylus pen has been activated and sensed. The sensor unit 100a of FIG. 8 can be used in any one of the methods No. 2 to No. 32 in Table 1 above. It is okay to do so.

[0135] FIG. 12 illustrates a sensor unit 100b included in a touch input device according to a second embodiment of the present invention. This is a drawing for

[0136] Referring to FIG. 12, the sensor unit 100b includes a plurality of first to fourth patterns 101b, 102b, 103b, The first to fourth patterns 101b, 102b, 103b, and 104b are the same as those shown in FIG. Unlike the sensor unit 100a, the sensor unit 100a is disposed on the same layer. The first and second patterns 101a and 102a are arranged together in the first layer, and the third and fourth patterns 103a and 104a are arranged together in the second layer. 04a is placed on a second layer that is different from the first layer.

[0137] The first and second patterns 101b and 102b correspond to the first and second patterns of the sensor unit 100a shown in FIG. Since the structure and arrangement are the same as those of the second patterns 101a and 102a, the detailed description will be omitted. Instead, a number of third and fourth patterns 103b, 104b will be described in detail below.

[0138] A large number of third patterns 103b are arranged along the first and second directions. are arranged on both sides of one first pattern 101b. The first pattern 101b is connected to the connecting pattern portion of the first pattern 101b, and the connecting pattern portion 103b is located at the center of the first pattern 101b. may be placed.

[0139] The third pattern 103b has a rectangular, polygonal, circular or elliptical shape. The third pattern 103b has an opening in which one fourth pattern 104b is disposed. The opening may be formed in a closed curve shape.

[0140] The third patterns 103b arranged along the second direction are electrically connected to each other through the conductive patterns. Two third patterns adjacent to each other along the second direction are connected to one conductive pattern. On the other hand, a number of third patterns arranged along the first direction may be electrically connected. The turns 103b are not electrically connected to each other. The arrayed third patterns are also electrically connected via the conductive patterns.

[0141] Each of the multiple fourth patterns 104b is disposed inside one third pattern 103b. The fourth pattern 104b is surrounded by one third pattern 103b. The shape of the fourth pattern 104b can correspond to the shape of the opening of the third pattern portion 103b. The fourth pattern 104b may have a rectangular, polygonal, circular or elliptical shape. It may be in the form of a plate with no part.

[0142] The fourth patterns 104b arranged along the second direction are electrically connected to the conductive patterns. Two fourth patterns adjacent to each other along the second direction are connected to one conductive pattern. The plurality of fourth patterns may be electrically connected by turns. The fourth pattern disposed at one end of 104b is electrically connected to the control unit shown in FIG. The fourth pattern 104b arranged at the other end may be a plurality of fourth patterns arranged along the first direction. The pattern is electrically connected to the conductive pattern 104m. The electrical connection paths of the fourth pattern 104 may be configured in the same manner.

[0143] The sensor unit 100b shown in FIG. 12 can be substituted for the sensor unit 100a shown in FIG. Therefore, the sensor unit 100b shown in FIG. 12 can also be subjected to various methods described in Table 1 above. It can sense the touch position of the object and drive and sense the stylus pen. Specifically, the sensor unit 100a shown in FIGS. 9 to 11 can be replaced with the sensor unit 100 shown in FIG. 12. In other words, the touch input device having the sensor unit 100b and the control unit 500 shown in FIG. The touch driving / sensing mode in Figure 9, the antenna driving mode in Figure 10, and the style in Figure 11 are shown. Furthermore, the sensor unit 100b of FIG. Any one of methods No. 2 to No. 32 in Table 1 above may also be used.

[0144] FIG. 13 is a diagram for explaining a modification of the sensor unit 100b shown in FIG.

[0145] Structure of the first to fourth patterns 101b, 102b, 103b, and 104b of the sensor unit 100b' shown in FIG. The shapes are the same as those of the first to fourth patterns 101b, 102b, 103b, and 104b of the sensor unit 100b shown in FIG. Therefore, the structures and shapes of the first to fourth patterns 101b, 102b, 103b, and 104b are the same as those of the first to fourth patterns 101b, 102b, 103b, and 104b. The explanation of (1) replaces the above-mentioned content.

[0146] The sensor unit 100b' shown in FIG. 13 differs from the sensor unit 100b shown in FIG. 12 in that the first panel Two first odd patterns 101o adjacent to each other in the first direction of the turn 101b and two adjacent The conductive patterns 101om electrically connect the first even patterns 101e.

[0147] The conductive pattern 101om is arranged to bypass the third and fourth patterns 103b and 104b without intersecting them. The conductive pattern 101om is formed by two third and fourth patterns adjacent to each other along the second direction. The conductive pattern may be disposed to intersect with the conductive pattern that electrically connects the electrodes 103b and 104b.

[0148] In the sensor unit 100b of FIG. 12, two first odd patterns 101o are adjacent to each other in the first direction. The conductive pattern electrically connecting two adjacent first even patterns 101e has two ends. The remaining part excluding the part has a shape extending in a straight line in the first direction, so that the third and fourth patterns 1 03b, 104b. A predetermined capacitor is formed between the conductive pattern and the third and fourth patterns 103b and 104b. The predetermined capacitance may be used for touch sensing or stylus sensing. This can affect the sensing sensitivity and can also affect the operating frequency bandwidth. Cut.

[0149] On the other hand, the conductive pattern 101om of FIG. 13 overlaps with the third and fourth patterns 103b and 104b. Since the third pattern 103b is not overlapped and is arranged to bypass the third pattern 103b, the capacitance described above is not formed. This reduces the impact on touch or stylus sensing sensitivity. This has the advantage of reducing the influence of the operating frequency bandwidth.

[0150] On the other hand, the conductive pattern in FIG. 12 is shorter than the conductive pattern 101om in FIG. 13. 13. The advantage of the conductive pattern 101om of FIG. 2 is that the resistance of the conductive pattern 101om is even smaller than that of the conductive pattern 101om of FIG.

[0153] The third and fourth patterns 103c and 104c correspond to the third and fourth patterns of the sensor unit 100b shown in FIG. Since the structure and arrangement of the fourth patterns 103b and 104b are the same as those of the fourth patterns 103a and 104b, a detailed description thereof will be omitted. Instead, the following will describe in detail a number of first and second patterns 101c, 102c.

[0154] Each of the multiple second patterns 102c is arranged to surround one third pattern 103c. One second pattern 102b has an opening in which one third pattern 103c is disposed. .

[0155] Each of the multiple first patterns 101c is arranged to surround one second pattern 102c. One first pattern 101c has an opening in which one second pattern 102c is disposed. .

[0156] One second pattern 102c is arranged inside one first pattern 101c, and one second pattern 102c One third pattern 103c is formed inside, and one fourth pattern 104 is formed inside one third pattern 103c. c is placed.

[0157] The first pattern 101c may have a shape corresponding to the second pattern 102c, and the third pattern The turn 103c may have a shape corresponding to the third pattern 104c. The four patterns 101c, 102c, 103c, and 104c may have shapes that correspond to each other.

[0158] The first and second patterns 101c and 102c may have a rectangular shape, but are not limited to this. Instead, it may have a polygonal, circular or elliptical shape.
