Description

Technical Field

[0001] The present invention relates to a multifunctional touch input device that can detect a touch position, drive a stylus pen, and detect the position of the stylus pen.

Background Art

[0002] FIG. 1 is a schematic drawing for explaining that the output voltage (Vout) of CVA (Capacitor Voltage Amplitude) changes according to the position of the stylus pen 10 on a conventional flexible display panel.

[0003] Referring to FIG. 1, the reason why the output of CVA differs depending on the position of the pen 10 on the flexible display panel is that the ratio of the impedances on both sides centered on the pen 10 on the sensing line changes.

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

[0005] Based on 10 distributed models, at a driving frequency of 300 kHz, the impedance of the capacitor is about 200 times greater than the resistance (120 (ohm) vs. 1 / (2 * 300 k * 25 pF) = 21 k (ohm)). Therefore, the capacitor is the main cause.

[0006] FIG. 2 shows that the output voltages (Vout1, Vout2) of CVA differ depending on the position of the pen 10 in FIG. 1. ​​​​​​​​​It is a drawing for explaining the above by means of current sensing Figure 3 shows that the output voltages (Vout1, Vout2) of the CVA differ depending on the position of the pen 10 in Figure 1 It is a drawing for explaining the above by means of voltage sensing 。

[0007] Referring to FIGS. 2 and 3, the output voltage of the CVA differs 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 side, the larger the output voltage of the CVA, and the farther it is from the sensing circuit unit 50 side, the smaller the output voltage of the CVA becomes

[0046] Various embodiments will now be described in detail with reference to the accompanying drawings.

[0047] FIG. 4 is a schematic diagram of a touch input device according to one embodiment of the present invention.

[0048] Referring to FIG. 4, a touch input device according to an embodiment of the present invention includes a sensor unit 100 and a control unit 500.

[0049] The sensor unit 100 includes a number of patterns (or a number of electrodes).

[0050] The sensor unit 100 may include a number of first to fourth patterns 101, 102, 103, 104.

[0051] The first pattern 101 has a shape extending along a first direction. In FIG. 4, the first direction is indicated by the major axis, but is not limited thereto. For example, the first direction may be the minor axis.

[0052] The first pattern 101 may include a number of main pattern portions and connection pattern portions connecting between two adjacent main pattern portions among the number of main pattern portions. Here, the main pattern portion may have a diamond shape, but is not limited thereto, and may have a different shape from the connection pattern portion as various shapes.

[0053] The first pattern 101 may have an opening in which the second pattern 102 is disposed. The shape of the opening may correspond to the outer shape of the first pattern 101. The first pattern 101 may have a structure surrounding the second pattern 102. The first pattern 101 is disposed at a predetermined interval from the second pattern 102.

[0054] The second pattern 102 is disposed inside the first pattern 101.

[0055] The second pattern 102 includes a number of main pattern portions and among the number of main pattern portions, ​​​​​​​​​It may include a connection pattern portion that connects between two main pattern portions adjacent thereto. Here the main pattern portion may have a diamond shape, but is not limited thereto, and may have a shape different from that of the connection pattern portion as various shapes.

[0056] The main pattern portion of the second pattern 102 may have a corresponding shape to the main pattern portion of the first pattern 101, and the connection pattern portion of the second pattern 102 may have a corresponding shape to the connection pattern portion of the first pattern 10 1. 1.

[0057] A large number of the first patterns 101 and the second patterns 102 are arranged in parallel with each other.

[0058] One end of a large number of the first patterns 101 is electrically connected to the control unit 500, and the other end is electrically open. Here, one end is a place relatively close to the control unit 500 and the other end is a place relatively far from the control unit 500. One end of a large number of the first patterns 101 may be electrically connected to each other via a conductive trace with the control unit 500.

[0059] One end of a large number of the second patterns 102 is electrically connected to the control unit 500, and the other end is electrically connected via a conductive trace. One end is a place relatively close to the control unit 500 and the other end is a place relatively far from the control unit 500. Here, if the other ends of a large number of the second patterns 102 are electrically connected to each other, a separate capacitor is added to each second pattern 102, so the overall impedance will decrease. Therefore, it has the same effect as if the other ends of a large number of the second patterns 102 become AC GND.

[0060] On the one hand, although not shown in the drawings, a number of the second patterns 102 are electrically connected to each other The other end may be grounded.

[0061] Also, although not shown in the drawings, the other ends of a number of the second patterns 102 are not electrically connected to each other Instead, a predetermined capacitor may be connected to the other end of each second pattern 102.

[0062] The first pattern 101 and the second pattern 102 may be arranged in the same layer. A metal mesh (metal mesh) can be used to form the first pattern 101 and the second pattern 102 in the same layer can be.

[0063] The third pattern 103 has a shape extending along the second direction. In FIG. 4, the second direction is shown by the minor axis, but is not limited thereto. For example, the second direction may be the major axis as well.

[0064] The third pattern 103 may include a number of main pattern portions and a connecting pattern portion that connects between two adjacent main pattern portions among the number of main pattern portions. Here The main pattern portion may have a diamond shape, but is not limited thereto, and may have a shape different from that of the connecting pattern portion as various shapes.

[0065] The third pattern 103 may have an opening in which the fourth pattern 104 is arranged. The shape of the opening may correspond to the outer shape of the third pattern 103. The third pattern 103 may have a structure surrounding the fourth pattern 104. The third pattern 103 is arranged at a predetermined interval from the fourth pattern 104.

[0066] ​​The fourth pattern 104 is disposed inside the third pattern 103.

[0067] The fourth pattern 104 may include a number of main pattern portions and connection pattern portions that connect between two adjacent main pattern portions among the number of main pattern portions. Here, the main pattern portions may have a diamond shape, but are not limited thereto, and may have a shape different from that of the connection pattern portions as various shapes. The main pattern portions of the fourth pattern 104 may have a corresponding shape to the main pattern portions of the third pattern 103, and the connection pattern portions of the fourth pattern 104 may have a corresponding shape to the connection pattern portions of the third pattern 10

[0068] 3. The third pattern 103 and the fourth pattern 104 are multiple and arranged parallel to each other. One end of the multiple third patterns 103 is electrically connected to the control unit 500, and the other end is electrically

[0069] open. Here, one end is relatively close to the control unit 500,

[0070] and the other end is relatively far from the control unit 500. One end of the multiple third patterns 103 may be electrically connected to each other via a conductive trace with the control unit 500. One end of the multiple fourth patterns 104 is electrically connected to the control unit 500, and the other end is electrically connected via a conductive trace. One end is relatively close to the control unit 500, and the other end is relatively far from the control unit 500. If the other ends of the multiple fourth patterns 104 are electrically connected to each other, a different capacitance is added to each fourth pattern 104

[0071] ​​​​Therefore, the overall impedance will decrease. Accordingly, a large number of fourth patterns 104 will have the same effect as if the other ends were connected to AC GND.

[0072] On the other hand, the other ends of a large number of fourth patterns 104 that are electrically connected to each other may be grounded. That's fine.

[0073] Also, although not shown in the drawings, a predetermined capacitor may be connected to the other end of each fourth pattern 104 without the other ends of a large number of fourth patterns 104 being electrically connected to each other. That's okay.

[0074] The third pattern 103 and the fourth pattern 104 may be arranged in the same layer. A metal mesh (metal mesh) can be used to form the third pattern 103 and the fourth pattern 104 in the same layer. Here, the third pattern 103 and the fourth pattern 104 may be arranged in a layer different from the first pattern 1 01 and the second pattern 102. For example, the first pattern 101 and the second pattern 102 may be arranged in the first layer, and the third pattern 103 and the fourth pattern 1 04 may be arranged in a second layer different from the first layer.

[0075] The control unit 500 is electrically connected to the sensor unit 100 and can control the operation of the sensor unit 100. The connection between the control unit 500 and the sensor unit 100 may be electrically connected via a conductive trace. That's okay.

[0076] The control unit 500 may include a number of drive circuit parts and a number of sensing circuit parts. The number of drive circuits The part may include a drive circuit part for touch sensing and a drive circuit part for stylus driving. The number of sensing circuit parts may include a sensing circuit part for touch sensing and a stylus sensor It may include a sensing circuit unit for sensing. Here, among a number of sensing circuit units, some sensing circuit units can perform both touch sensing and stylus sensing. .

[0077] The control unit 500 can control the sensor unit 100 to operate in any one of a touch sensing mode, an antenna driving mode, and a stylus sensing mode. The control unit 500 can control a number of drive / sensing circuit units to be connected to the sensor unit 100 according to each mode, and can control the drive signals applied to the number of drive circuit units. For this reason, the control unit 500 may include a number of switches for electrically connecting the number of drive / sensing circuit units and the sensor unit 100.

[0078] Hereinafter, each mode will be described with reference to FIGS. 5 to 7.

[0079] FIG. 5 is a drawing showing a case where the touch input device shown in FIG. 4 operates in a touch sensing mode (or a 2D sensing mode).

[0080] Referring to FIGS. 4 and 5, in the touch sensing mode, the control unit 500 can electrically connect a number of drive circuit units for touch sensing to the first pattern 101 of the sensor unit 100. The control unit 500 can control a number of switches sw to electrically connect the conductive traces connected to the number of first patterns 101 to the number of drive circuit units.

[0081] Also, the control unit 500 can electrically connect a number of sensing circuit units for touch sensing to the third pattern 103 of the sensor unit 100. The control unit 500 can control a number of switches Control the touch switch to electrically connect the conductive traces connected to a number of third patterns 103 to a number of sensing circuit parts.

[0082] In the touch sensing mode, the control unit 500 applies drive signals (or touch drive signals) for touch sensing simultaneously or sequentially to a number of first patterns 101, and receives sensing signals (or touch sensing signals) received from a number of third patterns 103. A number of sensing circuit parts of the control unit 500 electrically connected to a number of third patterns 103 can output capacitance change amount information included in the input sensing signals at a predetermined voltage value. The control unit 500 can process the output voltage value to detect the touch position.

[0083] In FIG. 5, although the control unit 500 is not electrically connected to a number of second patterns 102, a number of drive circuit parts can be electrically connected to a number of second patterns 102 so that capacitive coupling between the first pattern 101 and the second pattern 102 does not occur. At this time, the control unit 500 can control to apply the same drive signal as the drive signal applied to a number of first patterns 101 to a number of second patterns 102. Or, when a drive signal is applied to a number of first patterns 101, the control unit 500 can also control to apply a predetermined reference potential to a number of second patterns 102.

[0084] FIG. 6 is a drawing showing the case where the touch input device shown in FIG. 4 operates in an antenna drive mode (or a stylus drive mode, or a stylus uplink mode). ​​​​​​​​​​​​​

[0085] Referring to FIGS. 4 and 6, in the antenna driving mode, the control unit 500 electrically connects a number of driving circuit units for antenna driving to a number of second patterns 102 of the sensor unit 100. The control unit 500 can control a number of switches sw to electrically connect conductive traces connected to the number of second patterns 102 to the number of driving circuit units. The control unit 500 can control a number of switches sw to electrically connect conductive traces connected to the number of second patterns 102 to the number of driving circuit units. The control unit 500 can control a number of switches sw to electrically connect conductive traces connected to the number of second patterns 102 to the number of driving circuit units. It is possible.

[0086] The control unit 500 can control a drive signal (or pen drive signal) output from each drive circuit unit connected to a number of second patterns 102. It is possible.

[0087] For example, the control unit 500 controls so that a pulse signal of a predetermined frequency is output in the first drive circuit unit among a number of drive circuit units connected to a number of second patterns 102, and controls so that no pulse signal is output in the second drive circuit unit. In the third drive circuit unit, it can be controlled so that an inverted pulse signal having a phase opposite to the pulse signal output from the first drive circuit unit is output. In this case, a current loop is formed by the second pattern 102 electrically connected to the first drive circuit unit and the second pattern electrically connected to the third drive circuit unit. A magnetic field is generated by the formed current loop, and the stylus pen in contact with the sensor unit 100 may resonate and be driven by the magnetic field. Among them, in the first drive circuit unit, it is controlled so that a pulse signal of a predetermined frequency is output, in the second drive circuit unit, it is controlled so that no pulse signal is output, and in the third drive circuit unit, it is controlled so that an inverted pulse signal having a phase opposite to the pulse signal output from the first drive circuit unit is output. Among them, in the first drive circuit unit, it is controlled so that a pulse signal of a predetermined frequency is output, in the second drive circuit unit, it is controlled so that no pulse signal is output, and in the third drive circuit unit, it is controlled so that an inverted pulse signal having a phase opposite to the pulse signal output from the first drive circuit unit is output. Among them, in the first drive circuit unit, it is controlled so that a pulse signal of a predetermined frequency is output, in the second drive circuit unit, it is controlled so that no pulse signal is output, and in the third drive circuit unit, it is controlled so that an inverted pulse signal having a phase opposite to the pulse signal output from the first drive circuit unit is output. Among them, in the first drive circuit unit, it is controlled so that a pulse signal of a predetermined frequency is output, in the second drive circuit unit, it is controlled so that no pulse signal is output, and in the third drive circuit unit, it is controlled so that an inverted pulse signal having a phase opposite to the pulse signal output from the first drive circuit unit is output. Among them, in the first drive circuit unit, it is controlled so that a pulse signal of a predetermined frequency is output, in the second drive circuit unit, it is controlled so that no pulse signal is output, and in the third drive circuit unit, it is controlled so that an inverted pulse signal having a phase opposite to the pulse signal output from the first drive circuit unit is output. Among them, in the first drive circuit unit, it is controlled so that a pulse signal of a predetermined frequency is output, in the second drive circuit unit, it is controlled so that no pulse signal is output, and in the third drive circuit unit, it is controlled so that an inverted pulse signal having a phase opposite to the pulse signal output from the first drive circuit unit is output. Among them, in the first drive circuit unit, it is controlled so that a pulse signal of a predetermined frequency is output, in the second drive circuit unit, it is controlled so that no pulse signal is output, and in the third drive circuit unit, it is controlled so that an inverted pulse signal having a phase opposite to the pulse signal output from the first drive circuit unit is output.

[0088] The control unit 500 can control so that mutually opposite pulse signals are output from any two of a number of drive circuit units electrically connected to a number of second patterns 102. Therefore, the control unit 500 can variously change the size and position of the current loop. The control unit 500 can control so that mutually opposite pulse signals are output from any two of a number of drive circuit units electrically connected to a number of second patterns 102. The control unit 500 can control so that mutually opposite pulse signals are output from any two of a number of drive circuit units electrically connected to a number of second patterns 102. can be determined. For example, when the control unit 500 detects the position of a stylus pen close to the sensor unit 100 the control unit 500 controls the drive circuit unit electrically connected to two second patterns around the position of the stylus pen to output mutually opposing pulse signals. When the position of the stylus pen cannot be detected, the control unit 500 controls the drive circuit unit electrically connected to two second patterns located on the outermost sides of both sides among a number of second patterns 102 to output mutually opposing pulse signals. The control unit 500 can also simultaneously form two or more current loops. This will be described with reference to FIG. 7 FIGS. 7(a) to 7(c) are diagrams for explaining various methods of applying a pen drive signal for driving a stylus pen to a number of second patterns 102 shown in FIG. 4. For reference, in FIGS. 7(a) to 7(c), one second pattern 102 shown in FIG. 4 is simply shown as one line (Ch), and each line (Ch) forms one channel

[0089] FIG. 7(a) shows a case where the stylus pen 50 is located at the central part (a region other than the end part) of the sensor unit 100 shown in FIG. 4, for example, located on the fifth channel Ch5. In such a case, the control unit 500 controls a number of drive circuit units such that pulse signals and inverted pulse signals (or ground) are applied to the same number of channels (Ch2, Ch3, Ch4 / Ch6, Ch7, Ch8) on both the left and right sides based on the point where the stylus pen 50 is located as follows

[0090] Specifically, the control unit 500 controls the drive circuit units located on the left side of the stylus pen 50 to apply pulse signals and inverted pulse signals (or ground) to the same number of channels (Ch2, Ch3, Ch4 / Ch6, Ch7, Ch8) on both the left and right sides based on the point where the stylus pen 50 is located For reference, in FIGS. 7(a) to 7(c), one second pattern 102 shown in FIG. 4 is simply shown as one line (Ch), and each line (Ch) forms one channel FIG. 7(a) shows a case where the stylus pen 50 is located at the central part (a region other than the end part) of the sensor unit 100 shown in FIG. 4, for example, located on the fifth channel Ch5. In such a case, the control unit 500 controls a number of drive circuit units such that pulse signals and inverted pulse signals (or ground) are applied to the same number of channels (Ch2, Ch3, Ch4 / Ch6, Ch7, Ch8) on both the left and right sides based on the point where the stylus pen 50 is located as follows

[0091] FIG. 7(a) shows a case where the stylus pen 50 is located at the central part (a region other than the end part) of the sensor unit 100 shown in FIG. 4, for example, located on the fifth channel Ch5. In such a case, the control unit 500 controls a number of drive circuit units such that pulse signals and inverted pulse signals (or ground) are applied to the same number of channels (Ch2, Ch3, Ch4 / Ch6, Ch7, Ch8) on both the left and right sides based on the point where the stylus pen 50 is located For example, when the stylus pen 50 is located on the fifth channel Ch5 In such a case, the control unit 500 controls a number of drive circuit units such that pulse signals and inverted pulse signals (or ground) are applied to the same number of channels (Ch2, Ch3, Ch4 / Ch6, Ch7, Ch8) on both the left and right sides based on the point where the stylus pen 50 is located Specifically, the control unit 500 controls the drive circuit units located on the left side of the stylus pen 50 to apply pulse signals and inverted pulse signals (or ground) to the same number of channels (Ch2, Ch3, Ch4 / Ch6, Ch7, Ch8) on both the left and right sides based on the point where the stylus pen 50 is located to apply pulse signals and inverted pulse signals (or ground) to the same number of channels (Ch2, Ch3, Ch4 / Ch6, Ch7, Ch8) on both the left and right sides based on the point where the stylus pen 50 is located Control such that a pulse signal is applied to three second to fourth channels Ch2, Ch3, and Ch4 and control such that an inverted pulse signal is applied to three sixth to eighth channels Ch6, C h7, Ch8 located on the right side of the stylus pen 50. Here, in FIG. 7 (a), it is shown that a pulse signal and an inverted pulse signal (or, grounded) are applied to three channels on the left and right sides respectively with the stylus pen 50 as a reference, but it is not limited to this. For example, in FIG. 7(a), a pulse signal and an inverted pulse signal (or, grounded) may be applied to two or one channel on the left and right sides respectively with the stylus pen 50 as a reference, or a pulse signal and an inverted pulse signal (or, grounded) may be applied to four or more channels as well.

[0092] FIG. 7(b) shows a case where the stylus pen 50 is located at the end of the sensor unit 100 shown in FIG. 4 and, for example, is located between the 0th channel Ch0 and the 1st channel Ch1. Compared with FIG. 7(a), the control unit 500 cannot apply a pulse signal and an inverted pulse signal (or, grounded) to the same number of channels on the left and right sides with the stylus pen 50 as a reference. In such a case, the control unit 500 can control to apply a pulse signal and an inverted pulse signal (or, grounded) to different numbers of channels on the left and right sides with the stylus pen 50 as a reference. Specifically, it can control to apply a pulse signal to the 0th channel Ch0 and an inverted pulse signal to the 1st to 3rd channels Ch1, Ch2, Ch3. Although not shown in the drawing, when the stylus pen 50 is located at the outermost edge on the left side of the 0th channel Ch0, the 0th to 2nd channels Ch0, Ch1, C h2. It is also possible to control so that an inversion pulse signal is applied to h2.

[0093] In FIGS. 7(a) to 7(b), the larger the number of channels (Ch0, Ch1... Ch19), the more terminals of the control unit 500 for driving each channel are required, and the configuration of the drive circuit section in the control unit 500 becomes more complicated. Therefore, at least two or more channels that are adjacent to each other among the channels (Ch0, Ch1 ... Ch19) can be electrically connected and driven as one channel. Specifically, as shown in FIG. 7(c), it is to electrically connect two channels and configure them as one channel. When configured in this way, the two electrically connected channels are simultaneously applied with the same signal. FIG. 7(c) shows a configuration in which 20 channels (Ch0, Ch1... Ch19) are electrically connected in pairs to form 10 channels. Although not shown in the drawings, it is also possible to electrically connect three channels at a time and connect the remaining two electrically to form seven channels, or to electrically connect four channels at a time to form five channels.

[0094] FIG. 8 is a drawing showing the case where the touch input device shown in FIG. 4 operates in the stylus sensing mode (or the stylus downlink mode).

[0095] Referring to FIGS. 4 and 8, in the stylus sensing mode, the control unit 500 can electrically connect a number of sensing circuit sections for stylus sensing to the first pattern 102 and the third pattern 103 of the sensor unit 100. The control unit 500 has a number of switches and can... By controlling the switch, the conduction traces connected to a number of first patterns 101 and a number of third patterns 103 can be electrically connected to a number of sensing circuit portions. The touch input device according to an embodiment of the present invention has an advantage that the output voltage values of the multiple sensing circuit portions are hardly changed by the position of the stylus pen on the sensor unit 100 in the stylus sensing mode. The specific principle for this will be described with reference to FIGS. 9(a) to (f).

[0096] The touch input device according to an embodiment of the present invention, due to the configuration of the sensor unit 100, has the advantage that the output voltage values of the multiple sensing circuit portions are hardly changed by the position of the stylus pen on the sensor unit 100 in the stylus sensing mode. The specific principle for this will be described with reference to FIGS. 9(a) to (f). In the stylus sensing mode, the output voltage values of the multiple sensing circuit portions are hardly changed by the position of the stylus pen on the sensor unit 100. The specific principle for this will be described with reference to FIGS. 9(a) to (f). FIGS. 9(a) to (f) are diagrams for schematically explaining the operating principle of the stylus sensing mode of FIG. 8.

[0097] FIGS. 9(a) to (f) are diagrams for schematically explaining the operating principle of the stylus sensing mode of FIG. 8. FIG. 9(a) is a circuit diagram schematically modeling one of the first patterns 101 shown in FIG. 8 and the sensing circuit portion of the control unit 500 electrically connected thereto. FIG. 9(b) is a circuit diagram schematically modeling the second pattern 102 disposed inside one of the first patterns 101.

[0098] Referring to FIGS. 9(a) and (c), if the stylus pen approaches an arbitrary point A far enough away from the sensing circuit portion on the first pattern 101, a voltage (Vemf, hereinafter referred to as the "induced voltage") induced by the signal emitted from the stylus pen at the point A will be generated. FIG. 9(a) is a circuit diagram schematically modeling one of the first patterns 101 shown in FIG. 8 and the sensing circuit portion of the control unit 500 electrically connected thereto. FIG. 9(b) is a circuit diagram schematically modeling the second pattern 102 disposed inside one of the first patterns 101. FIG. 9(b) is a circuit diagram schematically modeling the second pattern 102 disposed inside one of the first patterns 101. FIG. 9(c) is a voltage distribution graph in the circuit diagram of FIG. 9(a), and FIG. 9(d) is a voltage distribution graph in the circuit diagram of FIG. 9(b).

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

[0100] Referring to FIGS. 9(a) and (c), if the stylus pen approaches an arbitrary point A far enough away from the sensing circuit portion on the first pattern 101, a voltage (Vemf, hereinafter referred to as the "induced voltage") induced by the signal emitted from the stylus pen at the point A will be generated. If the stylus pen approaches an arbitrary point A far enough away from the sensing circuit portion on the first pattern 101, a voltage (Vemf, hereinafter referred to as the "induced voltage") induced by the signal emitted from the stylus pen at the point A will be generated. If the stylus pen approaches an arbitrary point A far enough away from the sensing circuit portion on the first pattern 101, a voltage (Vemf, hereinafter referred to as the "induced voltage") induced by the signal emitted from the stylus pen at the point A will be generated. Generated.

[0101] If an induced voltage (Vemf) is generated at point A, the equivalent capacitance of the first pattern 101 when viewed from the left side of point A becomes small, so the equivalent impedance becomes large. Therefore, almost most of the induced voltage (Vemf) is applied to the left side of point A, and the right side of point A is almost 0 (V) and the voltage applied is close to 0 (V), and the current hardly flows. Moreover, the voltage close to almost 0 (V) on the right side of point A decreases further due to the equivalent resistance of the first pattern 101, and almost no voltage is applied to the input terminal of the sensing circuit unit.

[0102] Referring to FIGS. 9(b) and 9(d), if an induced voltage (Vemf) is generated at point A, the left side of point A is such that the other ends of each second pattern 102 are electrically connected to each other. Therefore, the equivalent capacitance when viewed from the left side of point A becomes large, so the equivalent impedance approaches almost 0. Thus, 0 (V) is applied to the left side of point A, and since one end of the second pattern 102 is open on the right side of point A , there is no voltage drop due to the equivalent resistance, and Vemf is applied as it is.

[0103] Comparing FIGS. 9(c) and 9(d), it can be confirmed that there is a potential difference of approximately Vemf at any position between the first pattern 101 and the second pattern 102. The potential difference of approximately Vemf between the first pattern 101 and the second pattern 102 causes a capacitive coupling between the first pattern 101 and the second pattern 102. Due to the capacitive coupling, as shown in FIG. 9(e), a current flows from the second pattern 102 to the first pattern 101. As shown in FIG. 9(a), when the position of the stylus pen is far from the sensing circuit unit of the control unit 500 ​​​​ However, the current generated from the first pattern 101 itself becomes less and less, but since current flows from the second pattern 102 into the first pattern 101, the current output from the first pattern 101 to the sensing circuit unit of the control unit 500 is almost the same as the position of the pen. Therefore, the control unit 500 can sense the position of the stylus pen through the sensing circuit unit electrically connected to the first pattern 101.

[0104] And as can be seen through (a) to (e) of FIG. 9, even if the point A moves to the left or right, the potential difference between the first pattern 101 and the second pattern 102 remains constant as Vemf. Therefore, regardless of whether the position of the stylus pen on the sensor unit 100 is close to or far from the sensing circuit unit, the control unit 500 can sense the stylus pen from the constant signal output from the sensing circuit unit.

[0105] On the other hand, in the description of (e) of FIG. 9, the current flowing from the second pattern 102 into the first pattern 101 was described as being due to capacitive coupling, but it is not limited to this. For example, the current flowing from the second pattern 102 into the first pattern 101 can also be due to magnetic coupling (magnetic field coupling).

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

[0107] Referring to FIG. 10, a touch input device according to another embodiment of the present invention includes a sensor unit 100 ' and a control unit 500'.

[0108] The sensor unit 100' includes a number of patterns.

[0119] The second b-pattern 102b is disposed inside the first b-pattern 101b.

[0120] The second b-pattern 102b may include an inverted triangular pattern portion, a triangular pattern portion, and a connecting pattern portion that connects between the inverted triangular pattern portion and the triangular pattern portion.

[0121] A number of first a-patterns 101a and a number of first b-patterns 101b are arranged alternately along the first direction, and the number of first a-patterns 101a are electrically connected to each other, and the number of first b patterns 101b are also electrically connected to each other.

[0123] section 500'. A number of second a-patterns 102a and a number of second b-patterns 102b are arranged alternately along the first direction and are electrically connected to each other. The number of second a-patterns 102a and the number of second

[0124] b-patterns 102b are arranged alternately along the first direction and are electrically connected to each other. b-patterns 102b are arranged alternately along the first direction and are electrically connected to each other. Of the b - pattern 102b, the second b - pattern 102b located at one end is electrically connected to the control unit 500, and the second a - pattern 102a located at the other end may be electrically connected to another adjacent second a - pattern.

The first a - pattern 101a, the first b - pattern 101b, the second a - pattern 102a, and the second b pattern 102b can be formed in the same layer using a metal mesh.

[0126] The control unit 500’ has the same function as the control unit 500 shown in FIG. 4.

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

[0128] Referring to FIGS. 10 and 11, in the touch - sensing mode, the control unit 500’ can electrically connect a drive circuit unit for touch sensing to the third pattern 103 of the sensor unit 100’. One drive circuit unit may be electrically connected to each of the multiple third patterns 103.

[0129] Also, the control unit 500’ can electrically connect a sensing circuit unit for touch sensing to the first a - and first b - patterns 101a, 101b of the sensor unit 100’.

[0130] In the touch sensing mode, the control unit 500' applies drive signals for touch sensing with a number of third patterns 103, and receives sensing signals received from a number of first a and first b patterns 101a, 1 01b. The sensing circuit unit of the control unit 500' electrically connected to the number of first a and first b patterns 101a, 101b can output a predetermined voltage value of the capacitance change amount information included in the input sensing signal. The control unit 500 ' can process the output voltage value to detect the touch position. Here, the control unit 500' can cancel out display noise and LGM noise by subtracting the sensing signal received from the first b pattern 10 1b from the sensing signal received from the first a pattern 101a.

[0131] Here, the control unit 500' controls so that the same drive signal is applied with a number of third patterns 103 and a number of fourth patterns 104 so that capacitive coupling does not occur between the third pattern 103 and the fourth pattern 104. (capacitive coupling) does not occur. Or, the control unit 500' can also control so that a reference potential is applied to a number of fourth patterns 104.

[0132]

[0133] FIG. 12 is a drawing showing a case where the touch input device shown in FIG. 10 operates in an antenna drive mode (or a stylus drive mode, or a stylus uplink mode).

[0133] Referring to FIGS. 10 and 12, in the antenna drive mode, the control unit 500' uses a drive circuit unit for antenna drive as the second a and second b patterns 102a, 10 of the sensor unit 100'. It can be electrically connected to 2b.

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

[0135] The control unit 500' can control so that mutually opposite pulse signals are output from any two of the number of drive circuit units electrically connected to a number of second a and second b patterns 102a, 102b. Therefore, the control unit 500' can variously change and set the magnitude and position of the current loop. For example, when the control unit 500' detects the position of the proximity stylus pen, it can control so that mutually opposite pulse signals are output from the drive circuit units electrically connected to the two second patterns around the position of the stylus pen. When the position of the stylus pen cannot be detected, two second a and second b patterns located at the outermost contours on both sides of a number of second a and second b patterns 102a, 102b ​​​​​​​​The drive circuit unit electrically connected to the b-patterns 102a and 102b can also be controlled to output mutually opposite pulse signals.

[0136] On the other hand, although not shown in a separate drawing, the control unit 500' can control the drive signal to be applied to a number of the first a-patterns 101a, or the first b-patterns 101b, or the third pattern 103. In this case, there is an advantage that the total number of channels can be reduced.

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

[0138] Referring to FIGS. 10 and 13, in the stylus sensing mode, the control unit 500' can electrically connect the sensing circuit unit for stylus sensing to the first a- and first b-patterns 101a, 101b and the third pattern 103 of the sensor unit 100', respectively.

[0139] In the stylus sensing mode, similar to the principle described via FIG. 8, if a stylus pen approaches any position of the sensor unit 100', a predetermined signal is output from the stylus pen, and an induced voltage is generated in the first a, first b, second a, second b, third, and fourth patterns 101a, 101b, 102a, 102b, 103, 104 by the output signal.

[0140] Here, when the stylus pen is located far from the control unit 500', although almost no current flows through the many first a-patterns 101a themselves due to the generation of the induced voltage, since current flows in from the many second a-patterns 102a, the control unit 500' has many first a-patterns ​ The position of the stylus pen can be detected through a sensing circuit unit electrically connected to the turn 101a. Here, the current flows from the second a-pattern 102a to the first a-pattern 101a because a potential difference of about the induced voltage is generated between the first a-pattern 101a and the second a-pattern 102a, and it is due to the capacitive coupling between the first a-pattern 101a and the second a-pattern 102a caused by the generated potential difference.

[0141] Similarly, although almost no current flows through the multiple first b-patterns 101b themselves, since current flows in from the multiple second b-patterns 102b, the control unit 500' can detect the position of the stylus pen through a sensing circuit unit electrically connected to the multiple first b-patterns 101b.

[0142] Similarly, although almost no current flows through the third pattern 103 itself, since current flows in from the fourth pattern 104, the control unit 500' can detect the position of the stylus pen through a sensing circuit unit electrically connected to the third pattern 103.

[0143] On the other hand, although not shown in the drawings, unlike FIG. 13, the control unit 500' can also electrically connect the sensing circuit unit to the multiple second a-patterns 102a, or the second b-patterns 102b, or the fourth pattern 104 to detect the position of the stylus pen.

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

[0145] The sensor unit 100'' of the touch input device shown in FIG. 14 is the sensor unit shown in FIG. 10. ​​​​​​​​​​Compared with 100'', the structures of the first a, first b, second a, second b, third, and fourth patterns are the same. The difference is that among a number of first b patterns 101b electrically connected to each other along the first direction, the first b pattern located on one side (the lower side) is electrically connected to the control unit 500'' via a conductive trace, and among a number of first a patterns 101a electrically connected to each other along the first direction, the first a pattern 101a located on the other side (the upper side) is electrically connected to the control unit 500'' via a conductive trace. That is, after a stylus pen approaches an arbitrary position on the sensor unit 100'', it is driven to sty

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

[0147] The description of the touch sensing mode is the same as that described in FIG. 11, so it is omitted.

[0148] FIG. 16 is a drawing showing a case where the touch input device shown in FIG. 14 operates in an antenna driving mode (or a stylus driving mode, or a stylus uplink mode).

[0149] The description of the antenna driving mode is the same as that described in FIG. 12, so it is omitted.

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

[0151] The stylus sensing mode in FIG. 17 is different from the stylus sensing mode in FIG. 15.

[0152] ​​​​​​​ 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. This is because. In other words, when the stylus pen is connected to a large number of first b patterns 101b When it is located far from the sensing circuit unit, the stylus pen has the characteristic of being located closer to the sensing circuit unit connected to a large number of first a patterns 1 01a.

[0155] Similarly, although almost no current flows through the third pattern 103 itself, since current flows in from the fourth pattern 104 the control unit 500’ can detect the position of the stylus pen through the sensing circuit unit electrically connected to the third pattern 103.

[0156] On the other hand, although not shown in the drawings, different from FIG. 17, the control unit 500’’ can also detect the position of the stylus pen by electrically connecting the sensing circuit unit to a large number of second a patterns 102a, or second b patterns 102b, or fourth pattern 104

[0167] A predetermined capacitance is formed between the plurality of drive electrodes TX0, TX1, TX2,... and the plurality of receiving electrodes RX0, RX1, RX2 ,..., particularly at these intersections. Such capacitance changes when a touch input occurs at or around that point. Therefore , by detecting the amount of change in capacitance from the signals output from the plurality of receiving electrodes RX0, RX1, RX2,..., the presence or absence of touch and touch input can be detected .

Although not shown in the drawings, the opposite case is also possible .

[0189] The sensor unit 200’ in FIG. 20 can further reduce the number of bridges compared with the sensor unit 200 in FIG. 19. This is due to the shape of a number of driving electrodes TX0’, TX1’, TX2’, ….

[0192] Referring to FIG. 21, the structures of the main pattern portions 101’, 102’, 103’, and 10 4’ of the first to fourth pattern portions are different from those in FIG. 4.

[0193] In FIG. 21, the outer contours of the second pattern portion 102’ or the fourth pattern portion 104’ are formed in an uneven structure, and the openings of the first pattern portion 101’ or the fourth pattern portion 104’ have a shape corresponding to the outer contour structure of the second pattern portion 102’ or the fourth pattern portion 104’. Such a structure can improve the mutual capacitance Cm value between the first pattern portion 101’ and the second pattern portion 102’ in the same layer, and can improve the mutual capacitance Cm value between the third pattern portion

[0194] 103’ and the fourth pattern portion 104’ in another same layer. The greater the improvement in the mutual capacitance Cm, the higher the voltage value output from the sensing circuit portion of the control unit 500 in the stylus sensing mode can be. Therefore, the stylus sensing sensitivity can be improved. Here, the modified example shown in FIG. 21 can also be directly applied to FIGS. 19 and 20.

[0197] The sensor unit 100’’ shown in FIG. 22 further includes a plurality of fifth patterns 105 and a plurality of sixth pattern portions 106 as compared with the sensor unit 100 shown in FIG. 4.

[0198] The plurality of fifth patterns 105 are arranged in the same layer (2 layer) as the plurality of first patterns 101​ They are arranged and arranged in large numbers along the first direction and the second direction.

[0199] Each fifth pattern 105 corresponds to a part of the main pattern part of the third pattern 103 arranged in another layer (1 st layer) and includes an overlapping shape. Also, the fifth pattern 105 is electrically connected to the fourth pattern 104 arranged in another layer (1 layer) via a via.

[0200] A large number of fifth patterns 105 can form a mutual capacitance Cm in a direction perpendicular to the large number of third patterns 103. Also, since the fifth pattern 105 is electrically connected to the fourth pattern 104 inside the third pattern 103, ultimately, the third pattern 103 can form a mutual capacitance Cm not only with the fourth pattern 104 but also with the fifth pattern 105. layer). layer). layer). layer).

Also, the sixth pattern portion 106 is electrically connected to the second pattern 102 inside the first pattern 101. Eventually, the first pattern 101 can form the mutual capacitance Cm not only with the second pattern 102 but also with the sixth pattern 105. Thus, the sensor unit 100’’ shown in FIG. 22 can form mutual capacitances not only in the horizontal direction but also in the vertical direction of the first pattern 101, and can form mutual capacitances not only in the horizontal direction but also in the vertical direction of the third pattern 103. This has the advantage. Therefore, in the stylus sensing mode, the voltage value output from the sensing circuit unit of the control unit 500 can be increased, and the stylus sensing sensitivity can be improved.

[0204] FIG. 23 is still another modified example of the sensor unit 100 in FIG. 4. The sensor unit 100’’’ shown in FIG. 23 has a part of the second pattern 102’ arranged in a layer different from the other part compared with the sensor unit 100 shown in FIG. 4. Specifically, the second pattern 102’ includes a plurality of main pattern portions and connection pattern portions connecting between two adjacent main pattern portions among the plurality of main pattern portions. However, the plurality of main pattern portions of the second pattern 102’ are arranged in a layer different from the plurality of connection pattern portions of the second pattern 102’. The plurality of main pattern portions of the second pattern 102’ are arranged in the same layer as the third pattern 103 and the fourth pattern 104, and the plurality of connection pattern portions of the second pattern 102’ are arranged in the same layer as the first pattern 101 as in FIG. 4.

[0209] The sensor unit 100’’’’ shown in FIG. 24 has a part of the fourth pattern 104’ arranged in a layer different from the remaining part compared to the sensor unit 100’’’ shown in FIG. 23. Specifically, the fourth pattern 104’ includes a number of main pattern portions and connection pattern portions that connect between two adjacent main pattern portions among the number of main pattern portions, wherein the number of main pattern portions of the fourth pattern 104’ are arranged in a layer different from the number of connection pattern portions of the fourth pattern 104’. The number of main pattern portions of the fourth pattern 104’ are arranged in the same layer as the first pattern 101, and the number of connection pattern portions of the fourth pattern 104’ are arranged in the same layer as the number of main pattern portions of the second pattern 102’ and the third pattern 103.

Therefore, the stylus sensing sensitivity can be further improved in the stylus sensing mode.

[0217] Since the main pattern portion 104a'' of the fourth pattern 104'' has a size larger than that of the main pattern portion of the fourth pattern 104' in FIG. 24, the corresponding area with the third pattern 103 becomes wider, and the mutual capacitance Cm between the fourth pattern 104'' and the third pattern 103 can be further improved. Therefore, the stylus sensing sensitivity can be further improved in the stylus sensing mode. Since the main pattern portion 104a'' of the fourth pattern 104'' has a size larger than that of the main pattern portion of the fourth pattern 104' in FIG. 24, the corresponding area with the third pattern 103 becomes wider, and the mutual capacitance Cm between the fourth pattern 104'' and the third pattern 103 can be further improved.

Also, unlike the second pattern 102' and the fourth pattern 104', and the second pattern 102 and the fourth pattern 104 of the sensor unit 100 in FIG. 4, since it does not have a diamond-shaped main pattern portion, when the display panel is located under the sensor unit 100''''' there is an advantage that the visibility can be further improved as compared with the sensor unit 100 in FIG. 4.
