Description

Pen and touch input system{PEN AND TOUCH INPUT SYSTEM}

This disclosure relates to pen and touch input systems.

Cell phones, smart phones, laptop computers, digital broadcasting terminals, PDAs (personal digital assistants), PMPs (portable multimedia players), navigation, slate PCs, tablet PCs, Various touch input devices such as ultrabooks and wearable devices are equipped with touch sensors.

In such a touch input device, the touch sensor may be located on a display panel that displays an image, or may be located in a portion of the touch input device. When a user interacts with a touch input device by touching the touch sensor, the touch input device can provide an intuitive user interface to the user.

Users can use a stylus pen for precise touch input. Stylus pens can be divided into active stylus pens and passive stylus pens depending on whether a battery and electronic components are provided inside.

Active stylus pens have superior basic performance compared to passive stylus pens and have the advantage of providing additional functions (pen pressure, hovering, buttons), but the pen itself is expensive and requires power to charge the battery. The downside is that there are not many actual users other than some advanced users.

Passive stylus pens have the advantage of being cheaper than active stylus pens and do not require batteries, but they have the disadvantage of being difficult to recognize precise touches compared to active stylus pens. However, recently, in order to implement a passive stylus pen capable of sophisticated touch recognition, EMR (Electro Magnetic Resonance) technology, which is an inductive resonance method, and capacitive resonance technology have been proposed.

The EMR method is superior in writing/drawing quality, which is the core function of a stylus pen, but has the disadvantage of being thicker and more expensive because a separate EMR sensor panel and EMR driving IC must be added in addition to the capacitance touch panel.

The capacitive resonance method uses a general capacitance touch sensor and touch controller IC without additional cost, but also supports pen touch by increasing the performance of the IC.

In the EMR method or capacitive resonance method, in order for the touch sensor to more accurately identify the touch by the stylus pen, the amplitude of the resonance signal must be large, and accordingly, the frequency of the driving signal transmitted to the stylus pen must be adjusted to the resonance built into the stylus pen. Make it approximately equal to the resonant frequency of the circuit. However, according to the conventional EMR method or the capacitive resonance method, even if the resonance frequency and the frequency of the driving signal match, the attenuation of signal transmission is very large, making signal transmission difficult. As a result, despite long-term attempts by numerous touch controller IC vendors, no company has yet succeeded in mass producing the touch controller because a sufficient output signal has not been produced.

Therefore, in order to manufacture an EMR type or capacitive resonance stylus pen that can produce the maximum output signal, how to design the internal resonance circuit and pen structure becomes a very important factor.

The present embodiments are intended to provide a pen and touch input system including a stylus pen capable of producing a sufficient output signal.

The problem to be solved by the present invention is to provide a pen and touch input system including a multi-functional touch input device that can detect a touch position, drive a stylus pen, and detect the position of the stylus pen.

Hereinafter, a sensor unit according to an embodiment of the present invention will be described with reference to the necessary drawings; A pen and touch input system including a touch input device including a control unit that controls the sensor unit, and a stylus pen capable of operating with the touch input device will be described.

FIG. 1A is a conceptual diagram showing a pen and touch input system including a stylus pen and a touch input device.

Referring to FIG. 1A, the stylus pen 10 receives (or uplinks) a signal output from the touch input device 2 or the touch screen 20 near the touch screen 20 of the touch input device 2. ), and can transmit (or downlink) a signal to the touch screen 20.

FIG. 1B is a diagram for explaining uplink and downlink in the pen and touch input system shown in FIG. 1A.

Referring to the left drawing of FIG. 1B, in the uplink, electromotive force (V2, or Vemf) is formed in the coil inside the stylus pen 10 of FIG. 1A. Referring to the right drawing of FIG. 1B, in the downlink, electromotive force (V1, or Vemf) is formed in the sensor unit of the touch input device 20. That is, the coil inside the stylus pen and the sensor unit of the touch input device operate as transformers.

FIG. 1B is a diagram for explaining the gap between the + driving channel and the - driving channel in the uplink.

Referring to FIG. 1C, in the uplink, the spacing between the + driving channel and the - driving channel is optimal depending on the shape and location of the inductor inside the stylus pen. As a general stylus pen design standard, it is desirable to widen the gap between the + drive channel and the - drive channel by at least 1 channel (4 mm).

Figure 2 is a diagram schematically showing a signal transmission operation between a stylus pen and a touch input device.

Referring to (a) of FIG. 2, the touch screen 20a includes a digitizer 29, a display panel 251, a sensor unit 21, and a window 22.

In the case of an EMR (Electro-Magnetic Resonance) type pen among passive stylus pens, when the digitizer 29 transmits a magnetic signal (B) to the EMR type stylus pen 10a, it is included in the stylus pen 10a. The resonant circuit resonates with the magnetic signal (B). Then, the digitizer 33 receives the resonated magnetic signal B from the stylus pen 10a.

The digitizer 29 may be attached below the display panel 251 and blocks the magnetic field generated by the FPCB (Flexible Printed Circuit Board) and the antenna loop formed with a plurality of conductive antenna loops, and the antenna loop blocks the magnetic field. It includes a ferrite sheet that blocks eddy currents that may be generated in other electrical devices and components when forming.

The FPCB consists of multiple antenna loops in multiple layers to detect the location where the resonance signal is input. One antenna loop has a form that overlaps with at least one other antenna loop in the Z-axis direction. As a result, the thickness of the FPCB is thick. Therefore, when using the digitizer 29, it is difficult to make the touch input device 2 thin and compact.

When such a digitizer 29 is mounted on the foldable/flexible touch input device 2, when folding occurs, deformation may occur in the FPCB attached to the folded area. Stress is applied to the wiring member forming the antenna loop due to repeated folding, which may ultimately result in damage to the wiring member. The ferrite sheet blocks the influence of the magnetic field generated by the antenna loop on the inside of the touch input device 2. The ferrite sheet is also thick, is prone to deformation when the touch input device 2 is folded, and can be damaged by repeated folding.

Referring to (b) of FIG. 2, the touch screen 20c includes a display panel 251, a sensor unit 21, and a window 22.

Then, the electrode (or pattern) of the sensor unit 21 can receive the resonated electromagnetic signal (E and/or B) from the stylus pen 10. When the electrode (or pattern) of the sensor unit 21 is formed of a metal mesh with low resistance, it is possible to detect a magnetic signal from the stylus pen 10.

Likewise, compared to the digitizer 29, the touch screen 20c does not require an additional unit or module to transmit a magnetic signal to the stylus pen 10, so the touch screen 20b can be made thinner and can be manufactured. There are also advantages in terms of cost.

Referring to (c) of FIG. 2, the touch screen 20b includes a loop coil 264, a display panel 251, a sensor unit 21, and a window 22.

In the case of the stylus pen 10 including a resonance circuit, when the loop coil 264 transmits a magnetic signal (B) to the stylus pen 10, the resonance circuit included in the stylus pen 10 transmits the magnetic signal (B). resonates with Then, the electrode (or pattern) of the sensor unit 21 can receive the resonated electromagnetic signal (E and/or B) from the stylus pen 10.

Compared to the digitizer 29, the loop coil 264 does not receive the magnetic signal B for detecting the touch position, so the wiring structure is simple and the touch screen 20b can be made thinner. As a result, the touch input device 2 can be made thinner and more compact. Additionally, since the loop coil 264 can be formed in various sizes and at various positions, this touch screen 20b can also be applied to the foldable/flexible touch input device 2.

The loop coil 264 may include a substrate on which the antenna loop is located and a ferrite sheet. The antenna loop may be formed from a conductive material such as copper, silver, etc. The antenna loop may be located on the same layer as the sensor unit 21 in addition to the substrate. In this case, the antenna loop may be formed of a conductive material exhibiting high transmittance and low impedance, such as metal mesh, ITO, graphene, silver nanowire, etc. You can. Additionally, the antenna loop may be located below the window, in which case the substrate may not be included in the loop coil 264.

In the above, the sensor unit 21 may include a plurality of electrodes (or patterns) for detecting touch coordinates. For example, the sensor unit 21 includes a plurality of first touch electrodes for detecting touch coordinates in a first direction and a plurality of second touch electrodes for detecting touch coordinates in a second direction intersecting the first direction. It can be included. In FIG. 2, the sensor unit 21 is shown as one layer, but the first touch electrode and the second touch electrode may be located on different layers, may be located overlapping with each other, or may not be located overlapping with each other. Alternatively, a separate layer may be interposed between the first touch electrode and the second touch electrode, but is not limited thereto.

Referring to (d) of FIG. 2, the touch screen 20d includes a display panel 251, a sensor unit 21, and a window 22.

In the case of the active stylus pen 10' including a resonance circuit, the resonance circuit included in the active stylus pen 10' is a power source within the active stylus pen 10' (for example, a battery for storing power (secondary It resonates using batteries (including batteries) and capacitors such as EDLC (electric double layered capacitor). Then, the electrode of the sensor unit 21 can receive the resonated electromagnetic signal (E and/or B) from the stylus pen 10'. When the electrode (or pattern) of the sensor unit 21 is formed of a metal mesh with low resistance, it is possible to detect a magnetic signal from the stylus pen 10'. The active stylus pen 10' may include a circuit that outputs an electromagnetic signal (E and/or B) having a predetermined frequency using a power source, as well as a resonance circuit to generate an electromagnetic signal. Additionally, the active stylus pen 10' may include both a resonance circuit and a circuit that outputs an electromagnetic signal (E and/or B) having a predetermined frequency.

The touch screen 20d can receive an electromagnetic signal from the stylus pen 10' without transmitting the magnetic signal to the stylus pen 10'. That is, the touch screen 20d does not require an additional unit or module to generate a signal to resonate the resonance circuit included in the stylus pen 10', so the touch screen 20d can be made thinner and more compact. , there are also advantages in terms of power consumption and manufacturing cost.

The touch unit 260 may be configured to detect the position, area, and capacitance at the time of touch of a touch object touching the touch area. Here, the touch object is an object that applies a touch to the touch screen, for example, a user's body part (finger, palm, etc.), a passive or active stylus pen 10, etc. It can be.

4 is a diagram showing a stylus pen according to embodiments.

The stylus pens of FIG. 4 commonly include a resonance circuit portion 12 within a housing.

The resonance circuit unit 12 is an LC resonance circuit and can resonate with a driving signal output from the touch screen 20 of FIGS. 2 and 3. The driving signal may include a signal (eg, a sine wave, a square wave, etc.) having a frequency corresponding to the resonance frequency of the resonance circuit unit 12. For resonance, the resonance frequency of the resonance circuit unit 12 and the frequency of the driving signal must be the same or very similar. The resonance frequency of the stylus pens 10a and 10b depends on the design value of the resonance circuit portion 12 of the stylus pens 10a and 10b. When the sensor unit 21 of FIG. 2(b) or the loop coil 264 of FIG. 2(c) generates an electromagnetic field due to a driving signal, the resonance circuit unit 12 of the stylus pens 10a and 10b generates a magnetic field. It resonates using the signal received through changes in .

Elements of the stylus pens 10a and 10b may be accommodated in the housing. The housing may have a cylinder shape, a polygonal pillar shape, a pillar shape with at least a portion of the curved surface, an entasis shape, a frustum of pyramid shape, a circular truncated cone shape, etc., but is not limited to the shape. Since the housing is empty inside, it can accommodate elements of the stylus pens 10a and 10b, such as the resonance circuit unit 12, therein. Such housing may be made of non-conductive material.

As shown in (a) of FIG. 4, the EMR type stylus pen 10a includes a resonance circuit unit 12. The resonance circuit unit 12 includes an inductor unit 14 and a capacitor unit 13. The inductor unit 14 includes a ferrite core 115 and a coil 116 wound on the outer surface of the ferrite core 115.

The EMR type stylus pen 10a may further include a tip 11a. The tip 11a is the end of the stylus pen 10a, and may be arranged to penetrate the ferrite core 115 as shown in (a) of FIG. 4, or may protrude from the ferrite core 115. The tip 11a may be non-conductive or may be composed of an electrode core made of a conductor, for example, a hard resin mixed with a conductive metal or conductive powder. Here, the tip 11a does not need to be electrically connected to the resonance circuit unit 12.

The ferrite core 115 may be, for example, a cylindrical ferrite material. The ferrite core 115 may be formed with an axial through hole having a predetermined diameter (for example, 1 mm) through which the tip 11a is inserted. In addition, the ferrite core 115 may be formed in the form of a cylinder, a polygonal pillar, a pillar with at least a portion of the curved surface, a double-sided pillar shape, a truncated pyramid shape, a truncated cone, a toroid, a ring shape, etc.

The coil 116 may be wound over the entire length of the ferrite core 115 in the axial direction, or may be wound over a portion of the length. The coil 116 is electrically connected to the capacitor unit 13.

The capacitor unit 13 may include a plurality of capacitors connected in parallel. Each capacitor on the printed board may have a different capacitance and may be trimmed during the manufacturing process.

As shown in (b) of FIG. 4, the electrically coupled resonance (ECR) type stylus pen 10b includes a conductive tip 11b and a resonance circuit unit 12. The resonance circuit unit 12 includes an inductor unit 14 and a capacitor unit 13 and may be grounded. The inductor unit 14 includes a ferrite core 115 and a coil 116 wound on the outer surface of the ferrite core 115.

The conductive tip 11b may be formed entirely or at least in part of a conductive material (eg, metal, conductive rubber, conductive fabric, conductive silicon, etc.), but is not limited thereto.

The coil 116 may be wound over the entire length of the ferrite core 115 in the axial direction, or may be wound over a portion of the length. The coil 116 is electrically connected to the capacitor unit 13.

The capacitor unit 13 may include a plurality of capacitors connected in parallel. Each capacitor on the printed board may have a different capacitance and may be trimmed during the manufacturing process.

Figure 5 is a conceptual diagram specifically showing the inductor portion of the stylus pen shown in Figures 4 (a) and (b).

Referring to FIG. 5, the inductor unit 14 includes a ferrite core 115 and a coil 116 wound around the ferrite core 115.

At this time, the inductance of the inductor unit 14 is determined by the following <Equation 1>.

As can be seen from Equation 1, the inductance (L) is proportional to the permeability of the ferrite core 115, the cross-sectional area of the coil 116, and the square of the number of turns, and is proportional to the winding length of the coil 116. It is inversely proportional.

The design of the inductor unit 14 in the resonance circuit unit 12 accommodated in the stylus pen shown in Figures 4 (a) and (b) is very important. In particular, in the design of the inductor unit 14, as shown in FIG. 6, the inductance (L) and Q value are very important parameters. Here, the Q value is a quantity representing the coil characteristics as a resonant circuit element, and is given as Q=2dfL/R. Here, L and R are the inductance and resistance of the coil, respectively, and f is the frequency. As a coil with a larger Q value is used, sharper resonance characteristics can be obtained.

In the design of the stylus pen shown in Figures 4 (a) and (b), L must have a sufficiently large self-resonance frequency for the frequency to be used, and the Q value must be the maximum at the frequency to be used. It is desirable to have a value. To satisfy this, the material of the ferrite core, type of coil wire, and winding scheme must be optimized. Additionally, a method is needed to obtain a high output signal while maintaining the diameter of a thin pen.

In the following embodiments, a design method for the most optimized stylus pen among multiple ferrite core materials, coil wire types, and winding schemes will be described.

(1) Material of ferrite core

Manganese (Mn) and nickel (Ni) were used as materials for the ferrite core used in this embodiment.

(2)　Wire type

Enameled wire and Litz wire were used as coil wire types used in this embodiment.

As shown in FIG. 7, the enamel wire 100 is a wire made by coating the surface of a copper wire 101 with insulating enamel 102 and heating it to a high temperature, and is used in windings of electrical devices, communication devices, and electrical instruments, etc. Used for wiring. In this embodiment, an enamel wire with a total thickness (T) of 0.2 mm, a wire diameter (Φ) of 0.18 mm, and a coating thickness (t) of 0.01 mm was used.

As shown in Figure 8, the LITZ wire 200 is made by twisting several strands of thin insulated wire (100, for example, enameled wire) with a diameter of about 0.1 mm into one line, and nylon, etc. It is a special insulated wire with an insulating coating (201). The litz wire 200 can reduce skin effect by increasing its surface area, and is used in coils of high-frequency circuits, etc.

In this embodiment, a Litz wire with a total thickness (T) of 0.2 mm, a wire diameter (Φ) of 0.06 mm, and a covering thickness (t) of 0.007 mm was used.

(3)　Winding method

In an embodiment of the present invention, a winding method with a multi-layer winding structure was used to obtain a sufficient inductance value (i.e., a sufficient number of turns) in the limited space of the stylus pen. Specifically, two types of multi-layer winding methods were used as shown in Figures 9 (A) and (B).

The winding method shown in (A) of FIG. 9 is the simplest winding method and is a sequential layer winding scheme in which the layer immediately above is wound once the winding of the lower layer is completed. At this time, the method (A) in FIG. 9 is a method in which the winding of the layer immediately above begins at the point where the winding of the previous layer ends, and hereinafter, this is referred to as the U-type winding method.

The winding method shown in (B) of FIG. 9 is an alternate layer winding scheme in which adjacent winding layers are wound alternately, and the windings of adjacent layers are wound obliquely in a zigzag shape. Hereinafter, this is referred to as the zigzag type winding method. Specifically, after sequentially winding the second layer winding over the first layer winding, the third layer winding is wound between the first layer winding and the second layer winding, and the fourth layer winding is wound over the second layer winding. After winding the winding, the 5th layer winding is wound between the 2nd layer winding and the 4th layer winding. This zigzag type winding method has the advantage of being able to minimize the voltage difference between windings of adjacent layers, thereby reducing winding self-capacitance. At this time, winding self-capacitance, a type of parasitic capacitance, is a parameter representing the electric field energy stored in the winding.

Comparative experiment 1 (Comparison of properties for each material)

The Q value was measured by changing the ferrite core material to manganese, nickel, and magnesium while the coil wire was wound using an enameled wire or U-type winding method.

As a result of the measurement, there was little difference in the Q value characteristics of each core material, and the measured Q value was also insufficient to implement into a product.

Comparative experiment 2 (Comparison of characteristics by winding type)

The Q value was measured for inductor 1 and inductor 2, which were manufactured using the ferrite core material as manganese (Mn) and U-type winding method, and the coil wire types were enamel wire and Litz wire, respectively.

Figure 8 is a diagram showing the Q values of inductor 1 and inductor 2 measured while changing the frequency using an E4980A precision LCR meter from KEYSIGHT TECHNOGIES.

In Figure 10, a is a waveform showing the change in Q value with respect to the frequency of inductor 1 (manganese core/enamel wire/U type winding method), and b is the frequency of inductor 2 (manganese core/Litz wire/U type winding method). This is a waveform that shows the change in Q value for .

In inductor 2 made of Litz wire, the Q value shows almost the maximum at a frequency around 400 kHz (frequency f1), and in inductor 1 made of enameled wire, the Q value shows almost the maximum at a frequency around 150 kHz (frequency f2).

As a result of comparing a and b of FIG. 10, it can be seen that the maximum Q value of inductor 2 is approximately 1.5 times higher than the maximum Q value of inductor 1. Therefore, it can be seen that the Litz wire is superior to the enamel wire as an inductor coil forming the resonance circuit of the stylus pen.

However, the maximum Q value of inductor 2 measured in comparative experiment 2 was only about half of the target value (Qtarget) required for commercialization.

Comparative experiment 3 (Comparison of characteristics by winding method)

The Q values were measured for inductors 3 to 5 manufactured by changing the wire type to enamel wire and Litz wire and the winding method to U type and zigzag type, with the ferrite core made of manganese (Mn).

Figure 11 is a diagram showing the Q values of inductors 3 to 5 measured while changing the frequency using an E4980A precision LCR meter from \KEYSIGHT TECHNOGIES.

In Figure 11, a is a waveform showing the change in Q value with respect to the frequency of inductor 3 (manganese core/enamel wire/U type winding method), and b is the frequency of inductor 4 (manganese core/enamel wire/zigzag type winding method). This is a waveform showing the change in Q value for , and c is a waveform showing the change in Q value for the frequency of inductor 5 (manganese core/Litz wire/zigzag type winding type).

As can be seen from the c waveform in FIG. 11, in inductor 5 manufactured using the Litz wire/zigzag winding method, the Q value is almost at its maximum at a frequency around 300 kHz (frequency f3). In inductor 4 manufactured using the enameled wire/zizzag winding method and inductor 3 manufactured using the enameled wire/U-type winding method, the Q value reaches its maximum at a frequency around 150 kHz (frequency f2).

Additionally, as a result of comparing a, b, and c in Figure 11, it can be seen that the maximum Q value of inductor 5 is almost 1.5 times higher than the maximum Q value of inductor 4, and is more than twice higher than the maximum Q value of inductor 3. . Therefore, it can be seen that the zigzag type winding method of the inductor forming the resonance circuit of the stylus pen is superior to the U type winding method.

However, it was only about 3/4 of the target value (Qtarget) required for commercialization of inductor 5 (manganese core/Litz wire/zigzag type winding method) measured in comparative experiment 2.

Comparative experiment 4 (Comparison of characteristics by core material)

In this embodiment, manganese and nickel were used as materials for the ferrite core, and the permeability of nickel is usually known to be 200-300, and the permeability of manganese is known to be 3000-5000.

Since the manganese used in this embodiment has a permeability approximately 15 times higher than that of nickel, assuming that the cross-sectional area and length of the coil are the same, the number of turns of manganese must be reduced by approximately 4 times that of nickel to obtain the same inductance value. There are advantages to this. Therefore, looking only from the perspective of the number of turns, it can be seen that it is more effective to use manganese rather than nickel.

Meanwhile, since the inductor unit 14 has a complex structure including a coil wound around the core, parasitic capacitance is additionally formed. Since the Q value decreases due to this parasitic capacitance, there is a problem of reducing the amplitude of the resonance signal.

The parasitic capacitance formed in the inductor unit 14 may occur between the wound coils and between the core and the coil. As described above, the parasitic capacitance between the wound coils can be reduced by adopting a zigzag type winding method. .

Meanwhile, in this embodiment, in order to reduce the parasitic capacitance between the core and the coil, a core material with a lower dielectric constant than manganese was tested, and as a result of the test, it was confirmed that the nickel core was the optimal material for the ferrite core.

An important physical characteristic of manganese and nickel, which are mainly used as ferrite core devices, is permeability, which has a significant effect on the inductance value as shown in Equation 1. However, in manganese and nickel as ferrite elements, permittivity is a physical property of little interest, and in fact, in the case of nickel, there is no relevant information even in the data sheet provided by the manufacturer.

In this embodiment, in order to check the permittivity of manganese and nickel, the permittivity of manganese and nickel was measured using an E4980A precision LCR meter from KEYSIGHT TECHNOGIES, and the measurement results are shown in Table 1 below.

Measurement 1 and Measurement 2 were measured using the same E4980A precision LCR meter from KEYSIGHT TECHNOGIES, and Measurement 1 represents the dielectric constant automatically calculated by the measurement software. According to Measurement 1, it can be seen that the dielectric constant of manganese is 2400, but the dielectric constant of nickel is not measured.

Measurement 2 is a method of calculating the dielectric constant by measuring the capacitance, area, and distance between the ferrite cores. According to Measurement 2, the dielectric constant of manganese was measured to be 8300 and that of nickel was measured to be 2.

There is a large difference in the dielectric constant results between Measurement 1 and Measurement 2, and in particular, in the case of Measurement 2, it was confirmed that there was a significant error depending on capacitance, area, distance, etc. However, as a result of Measurement 1 and Measurement 2, it can be seen that the dielectric constant of nickel is at least 1/1000 smaller than that of manganese.

In Comparative Experiment 4, the Q value was measured for inductors 6 and 7, which were manufactured by changing the winding method to U type and zigzag type, with the ferrite core material being nickel and the wire type being Litz wire.

Figure 12 is a diagram showing the Q values of inductor 6 and inductor 7 measured while changing the frequency using an E4980A precision LCR meter from KEYSIGHT TECHNOGIES.

In Figure 12, a is a waveform showing the change in Q value with respect to the frequency of inductor 6 (nickel core/Litz wire/U type winding method), and b is the frequency of inductor 7 (nickel core/Litz wire/zigzag type winding method). This is a waveform that shows the change in Q value for .

As can be seen from the waveform b in Figure 12, in inductor 7 manufactured using the nickel core/Litz wire/zigzag winding method, the Q value is almost at its maximum at a frequency around 400 kHz (frequency f5). In inductor 6 manufactured using the nickel core/Litz wire/U type winding method, the Q value is almost at its maximum at a frequency around 200 kHz (frequency f6). As a result of comparing a and b in Figure 11, it can be seen that the maximum Q value of inductor 7 is almost twice higher than the maximum Q value of inductor 6.

Meanwhile, it was found that the maximum Q value of inductor 7 (nickel core/Litz wire/zigzag type winding method) measured in comparative experiment 4 almost reached the target value (Qtarget) required for commercialization.

In comparative experiments 1 to 4 described above, the Q value was tested by manufacturing inductors by changing the combination of ferrite core material, coil wire type, and winding scheme, and the test results showed that nickel core, Litz wire, and zigzag It was found that the highest Q value was obtained when the inductor part of the capacitive resonance stylus pen was designed using a type of winding method. And, it was found that the maximum Q value of the inductor manufactured by this combination reached the target value (Qtarget) for commercialization.

Meanwhile, in this embodiment, a nickel core was used as a ferrite core and a Litz wire was used as a wire type of the core. However, in addition to the nickel core, a material with a dielectric constant of 1000 or less was used as the ferrite core, and in addition to the Litz wire, one coil was made of two or more wires. Similar results may be obtained when using a bundle of wire wrapped around an insulated wire (strand).

Below, before explaining in detail the touch input device in the pen and touch input system according to the embodiment of the present invention, the reason why the output voltage (Vout) of CVA (Capacitor Voltage Amplitude) varies depending on the position of the stylus pen on the touch screen is explained. Explain.

FIG. 13 is a schematic diagram to explain that the output voltage (Vout) of CVA (Capacitor Voltage Amplitude) varies depending on the position of the stylus pen 10 on a conventional touch screen.

Referring to FIG. 13, the reason why the output of the CVA varies depending on the position of the stylus pen 10 on the touch screen is that the impedance ratio on both sides of the sensing line around the stylus pen 10 varies. .

Based on the long axis of a conventional touch screen, the resistance (R) of the metal mesh touch sensor is approximately 1.2k (ohm), and the capacitor (C) is approximately 250pF.

Based on 10 distributed models, at a driving frequency of 300kHz, the impedance of the capacitor is approximately 200 times that of the resistor (120 (ohm) vs. 1/(2ð*300k*25pF) = 21k (ohm) )) It's bigger. Therefore, capacitors are the main cause.

Figure 14 is a diagram for explaining through current sensing that the output voltages (Vout1, Vout2) of the CVA are different depending on the position of the stylus pen 10 in Figure 13, and Figure 15 is a diagram showing the stylus pen ( 10) This is a diagram to explain through voltage sensing that the output voltages (Vout1, Vout2) of the CVA are different depending on the position.

Referring to Figures 14 and 15, the output voltage of the CVA varies depending on the position of the stylus pen 10 on the sensing line. That is, the closer the stylus pen 10 is to the sensing circuit unit 50, the larger the output voltage of the CVA is, and the farther away the stylus pen 10 is from the sensing circuit unit 50, the smaller the output voltage of the CVA is.

Hereinafter, a touch input device according to various embodiments of the present invention will be described in detail through the attached drawings.

One end is relatively close to the control unit 500, and the other end is relatively far from the control unit 500. Here, when other ends of the plurality of second patterns 102 are electrically connected to each other, capacitances for each second pattern 102 are added, so that the total impedance is reduced. Accordingly, the same effect is achieved as if the other ends of the plurality of second patterns 102 are AC GND.

The third pattern 103 has a shape extending along the second direction. In Figure 16, the second direction is shown in the minor axis, but it is not limited thereto. For example, the second direction may be the long axis.

The third pattern 103 may include a plurality of main pattern parts and a connection pattern part connecting two main pattern parts adjacent to each other among the plurality of main pattern parts.

It may include a connection pattern portion connecting the two. Here, the main pattern portion may have a diamond shape, but is not limited to this, and may have various shapes different from the connection pattern portion.

When other ends of the plurality of fourth patterns 104 are electrically connected to each other, capacitances for each fourth pattern 104 are added, so that the total impedance is reduced. Accordingly, the same effect is achieved as if the other ends of the plurality of fourth patterns 104 are AC GND.

Here, the third pattern 103 and the fourth pattern 104 may be disposed on different layers from the first pattern 101 and the second pattern 102. For example, the first pattern 101 and the second pattern 102 may be disposed on a first layer, and the third pattern 103 and fourth pattern 104 may be disposed on a second layer different from the first layer. You can.

The control unit 500 is electrically connected to the sensor unit 100 and can control the operation of the sensor unit 100. The control unit 500 and the sensor unit 100 may be electrically connected to each other through conductive traces. Here, the control unit 500 may be the touch controller 262 shown in FIG. 3, but is not limited thereto. The control unit 500 may be an integration of the touch controller 262 and the display controller 252 shown in FIG. 3, or may be an integration of the touch controller 262 and the control unit 270 shown in FIG. 3, The touch controller 262, display controller 252, and control unit 270 shown in FIG. 3 may be integrated.

The control unit 500 may include multiple driving circuit units and multiple sensing circuit units. The plurality of driving circuit units may include a driving circuit unit for touch sensing and a driving circuit unit for driving the stylus. The plurality of sensing circuits may include a sensing circuit for touch sensing and a sensing circuit for stylus sensing. Here, some of the plurality of sensing circuit units may perform touch sensing and stylus sensing.

The control unit 500 may 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 may connect a plurality of driving/sensing circuit units to the sensor unit 100 according to each mode and control driving signals to be applied to the plurality of driving circuit units. To this end, the control unit 500 may include a plurality of switches for electrically connecting a plurality of driving/sensing circuit units and the sensor unit 100.

Hereinafter, each mode will be described with reference to FIGS. 17 to 21.

FIG. 17 is a diagram illustrating a case where the touch input device shown in FIG. 16 operates in touch sensing mode (or 2D sensing mode).

Referring to FIGS. 16 and 17 , in the touch sensing mode, the control unit 500 may electrically connect a plurality of driving circuit units for touch sensing to the first pattern 101 of the sensor unit 100. The control unit 500 may control the plurality of switches sw to electrically connect the conductive traces connected to the plurality of first patterns 101 with the plurality of driving circuit units.

Additionally, the control unit 500 may electrically connect a plurality of sensing circuit units for touch sensing to the third pattern 103 of the sensor unit 100. The control unit 500 may control the plurality of switches sw to electrically connect the conductive traces connected to the plurality of third patterns 103 with the plurality of sensing circuit units.

In the touch sensing mode, the control unit 500 simultaneously or sequentially applies a driving signal (or touch driving signal) for touch sensing to at least one first pattern among the plurality of first patterns 101, and A detection signal (or touch detection signal) received from at least one third pattern among the three patterns 103 is received. The plurality of sensing circuit units of the control unit 500 electrically connected to the plurality of third patterns 103 may output capacitance change information included in the input sensing signal as a predetermined voltage value. The control unit 500 may detect the touch position by processing the output voltage value.

In FIG. 17, the control unit 500 is not electrically connected to the plurality of second patterns 102, but capacitive coupling occurs between the first pattern 101 and the second pattern 102. To prevent this, a plurality of driving circuit units may be electrically connected to the plurality of second patterns 102. At this time, the control unit 500 may control the same driving signal applied to the first plurality of patterns 101 to be applied to the second plurality of patterns 102 . Alternatively, the control unit 500 may control such that when a driving signal is applied to the first plurality of patterns 101, a predetermined reference potential is applied to the second plurality of patterns 102.

FIG. 18 is a diagram illustrating a case where the touch input device shown in FIG. 16 operates in antenna driving mode (or stylus driving mode, or stylus uplink mode).

Referring to FIGS. 16 and 18 , in the antenna driving mode, the control unit 500 may electrically connect a plurality of driving circuit units for driving the antenna to the plurality of second patterns 102 of the sensor unit 100. The control unit 500 may control the plurality of switches sw to electrically connect the conductive traces connected to the plurality of second patterns 102 with the plurality of driving circuit units.

The control unit 500 may control the driving signal (or pen driving signal) output from each driving circuit unit connected to the plurality of second patterns 102.

For example, the control unit 500 controls the first driving circuit unit among the plurality of driving circuit units connected to the plurality of second patterns 102 to output a pulse signal of a predetermined frequency, and the second driving circuit unit outputs any pulse signal. The third driving circuit unit can be controlled to output an inverted pulse signal whose phase is opposite to that of the pulse signal output from the first driving circuit unit. In this case, a current loop is formed with the second pattern 102 electrically connected to the first driving circuit portion and the second pattern electrically connected to the third driving circuit portion. A magnetic field is generated by the formed current loop, and the resonance circuit part of the stylus pen close to the sensor unit 100 is resonated and driven by the magnetic field.

The control unit 500 may control driving signals (eg, pulse signals) that conflict with each other to be output from any two driving circuit units among the plurality of driving circuit units electrically connected to the plurality of second patterns 102 . Accordingly, the control unit 500 can change and set the size or location of the current loop in various ways. For example, when the control unit 500 detects the position of a stylus pen close to the sensor unit 100, conflicting driving signals are output from the driving circuit unit electrically connected to the two second patterns around the position of the stylus pen. It can be controlled as much as possible, and if the position of the stylus pen is not detected, opposing driving signals are output from the driving circuit unit electrically connected to the two second patterns located on the outermost sides on both sides among the plurality of second patterns 102. You can also control it.

The control unit 500 may form two or more current loops simultaneously. This will be explained with reference to FIG. 19.

Figures 19 (a) to (c) are diagrams for explaining various methods in which the control unit 500 applies a pen driving signal for driving a stylus pen to the plurality of second patterns 102 shown in Figure 16. . For reference, in (a) to (c) of FIG. 19, one second pattern 102 shown in FIG. 16 is briefly shown as one line (Ch), and each line (Ch) is one line (Ch). It becomes a channel.

(a) of FIG. 19 is a case where the stylus pen 50 is located in the center (an area other than the edge) of the sensor unit 100 shown in FIG. 16, for example, on the fifth channel (Ch5). In this case, the control unit 500 uses the same number of channels (Ch2, Ch3, Ch4 / Ch6, Ch7, Ch8) on both left and right sides based on the point where the stylus pen 50 is located. ) can be controlled to apply multiple driving circuit units. Specifically, the control unit 500 controls the pulse signal to be applied to the three second to fourth channels (Ch2, Ch3, Ch4) located on the left side of the stylus pen 50, and the pulse signal located on the right side of the stylus pen 50. The reverse pulse signal can be controlled to be applied to the three sixth to eighth channels (Ch6, Ch7, and Ch8). Here, in (a) of FIG. 19, a pulse signal and an inverted pulse signal (or ground) are shown to be applied to three channels on the left and right, respectively, based on the stylus pen 50, but the present invention is not limited to this. For example, in (a) of Figure 19, a pulse signal and an inverted pulse signal (or ground) may be applied to two or one channel on the left and right, respectively, based on the stylus pen 50, and may be applied to four or more channels. A pulse signal and an inverted pulse signal (or ground) may be applied.

Figure 19(b) is a case where the stylus pen 50 is located at the edge of the sensor unit 100 shown in Figure 16, for example, between the 0th channel (Ch0) and the first channel (Ch1). will be. Compared to (a) of FIG. 19, the control unit 500 cannot apply a pulse signal and an inverted pulse signal (or ground) to the same number of channel(s) on the left and right with respect to the stylus pen 50. In this case, the control unit 500 may control the pulse signal and the inverted pulse signal (or ground) to be applied to different numbers of channels on the left and right sides of the stylus pen 50. Specifically, it can be controlled to apply a pulse signal to the 0th channel (Ch0) and an inverted pulse signal to the 1st to 3rd channels (Ch1, Ch2, and Ch3). Although not shown in the drawing, when the stylus pen 50 is located at the leftmost edge of the 0th channel (Ch0), the inverted pulse signal is controlled to be applied to the 0th channel to the second channel (Ch0, Ch1, Ch2). You may.

19 (a) to 19 (b), the more channels (Ch0, Ch1,...,Ch19) there are, the more terminals of the control unit 500 are required to drive each channel, and the more terminals in the control unit 500 are required. The configuration of the driving circuit part becomes complicated. Accordingly, at least two channels (Ch0, Ch1...Ch19) that are adjacent to each other can be electrically connected to be driven as one channel. Specifically, as shown in (c) of FIG. 19, 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. Figure 19 (c) shows 20 channels (Ch0, Ch1,..., Ch19) electrically connected two each to form 10 channels. Although not shown in the drawing, 7 channels can be configured by electrically connecting 3 at a time and the remaining 2 are electrically connected, or 5 channels can be configured by electrically connecting 4 at a time.

FIG. 20 is a diagram illustrating a case where the touch input device shown in FIG. 16 operates in stylus sensing mode (or stylus downlink mode).

16 and 20, in the stylus sensing mode, the control unit 500 electrically connects a plurality of detection circuits for stylus sensing to the first pattern 102 and the third pattern 103 of the sensor unit 100. It can be connected. The control unit 500 may control the plurality of switches sw to electrically connect the conductive traces connected to the plurality of first patterns 101 and the plurality of third patterns 103 with the plurality of sensing circuit units.

The touch input device according to an embodiment of the present invention has a configuration of the sensor unit 100 in which the output voltage values of the plurality of sensing circuit units hardly change depending on the position of the stylus pen on the sensor unit 100 in the stylus sensing mode. It has advantages. The specific principle for this will be explained with reference to (a) to (f) of FIG. 21.

Figures 21 (a) to (f) are diagrams for schematically explaining the operating principle of the stylus sensing mode of Figure 20.

FIG. 21 (a) is a circuit diagram schematically modeling a first pattern 101 shown in FIG. 20 and a detection circuit of the control unit 500 electrically connected thereto, and FIG. 21 (b) is a circuit diagram schematically modeling one of the first patterns 101 shown in FIG. This is a circuit diagram schematically modeling the second pattern 102 disposed inside one first pattern 101.

Figure 21(c) is a voltage distribution graph in the circuit diagram of Figure 21(a), and Figure 21(d) is a voltage distribution graph in the circuit diagram of Figure 21(b).

Referring to (a) and (c) of FIGS. 21, when the stylus pen approaches any point A on the first pattern 101 that is as far away as possible from the sensing circuit unit, the signal emitted from the stylus pen at the point A An induced voltage (Vemf, hereinafter referred to as 'induced voltage') is generated.

When an induced voltage (Vemf) is generated at point A, the equivalent capacitance of the first pattern 101 viewed from point A to the left decreases, and thus the equivalent impedance increases. Therefore, most of the induced voltage (Vemf) is applied to the left side of point A, and a voltage close to 0 (V) is applied to the right side of point A, so that almost no current flows. In addition, the voltage close to 0 (V) on the right side of point A gradually decreases due to the equivalent resistances of the first pattern 101, so that almost no voltage is applied to the input terminal of the sensing circuit unit.

Referring to (b) and (d) of Figure 21, when an induced voltage (Vemf) is generated at point A, the left side of point A is point A because the other ends of each second pattern 102 are electrically connected to each other. The equivalent capacitance looking to the left increases, so the equivalent impedance approaches almost 0. Therefore, 0 (V) is applied to the left of point A, and since one end of the second pattern 102 is open to the right of point A, no voltage drop occurs in the equivalent resistances and Vemf is applied as is.

Comparing (c) and (d) of FIG. 21, it can be confirmed that a potential difference equal to Vemf exists between the first pattern 101 and the second pattern 102 at any position. A potential difference equal to Vemf between the first pattern 101 and the second pattern 102 causes capacitive coupling between the first pattern 101 and the second pattern 102. Due to the capacitive coupling, current flows from the second pattern 102 to the first pattern 101, as shown in (e) of FIG. 21. As shown in (a) of FIG. 21, as the position of the stylus pen moves away from the sensing circuit part of the control unit 500, the current generated from the first pattern 101 itself gradually decreases, but the second pattern 102 ), the current flows into the first pattern 101, so the current output from the first pattern 101 to the sensing circuit of the control unit 500 has little difference from the position of the pen. Accordingly, the control unit 500 can detect the position of the stylus pen through a sensing circuit unit electrically connected to the first pattern 101 and the third pattern 103.

And, as can be seen from (a) to (e) of Figure 21, even if point A moves to the left or right, the potential difference between the first pattern 101 and the second pattern 102 is constant as Vemf. You can. Accordingly, the control unit 500 can sense the stylus pen from a constant signal output from the detection circuit unit, regardless of whether the position of the stylus pen on the sensor unit 100 is close to or far from the detection circuit unit.

Meanwhile, in the description of (e) of FIG. 21, it is explained that the current flowing from the second pattern 102 to the first pattern 101 is due to capacitive coupling, but it is not limited thereto. For example, the current flowing from the second pattern 102 to the first pattern 101 can be achieved through magnetic coupling (magnetic field coupling).

In order for the sensor unit 100 of the touch input device shown in FIG. 16 to drive and sense the stylus pen, a plurality of first to fourth patterns 101, 102, 103, and 104 are used in various ways. Can be used as a combination. Various combinations are shown in <Table 2> below. In <Table 2> below, '1' represents a plurality of first patterns 101, '2' represents a plurality of second patterns 102, '3 represents a plurality of third patterns 103, and '4' represents a plurality of first patterns 101. ' refers to the plurality of fourth patterns 104.

Referring to <Table 2> above, in various combinations (No. 1 to No. 32), a plurality of first patterns 101 and a plurality of third patterns 103 are used to detect the touch of an object such as a finger. Sensing. Specifically, by the control unit 500, the first plurality of patterns 101 operate as touch driving electrodes, and the plurality of third patterns 103 operate as touch receiving electrodes. Meanwhile, although not shown in the table, the plurality of first patterns 101 may operate as touch receiving electrodes and the plurality of third patterns 103 may operate as touch driving electrodes by the control unit 500.

One or two of the first to fourth patterns 101, 102, 103, and 104 may operate as a stylus driving electrode for driving the stylus pen by the control unit 500. A current loop for driving the stylus pen can be formed using one or two of the first to fourth patterns 101, 102, 103, and 104. X-axis driving uses one of a plurality of first patterns 101 and a plurality of second patterns 102, and Y-axis driving uses one of a plurality of third patterns 103 and a plurality of fourth patterns 104. It can be any one of them. The stylus pen can be driven either by X-axis drive or Y-axis drive, or by both.

At least two of the first to fourth patterns 101, 102, 103, and 104 may operate as sensing electrodes that sense a stylus pen signal emitted from the stylus pen. Since both X-axis sensing and Y-axis sensing are required to sense a stylus pen signal, two of the first to fourth patterns 101, 102, 103, and 104 are used. X-axis sensing may be one of a plurality of first patterns 101 and a plurality of second patterns 102, and Y-axis sensing may be one of a plurality of third patterns 103 and a plurality of fourth patterns ( 104).

In <Table 2> above, 'uplink signal size' refers to the size of the driving signal for driving the stylus pen. When comparing the size of the signal received by the stylus pen by applying the same stylus pen driving signal to each of the plurality of first patterns 101 and the plurality of second patterns 102, the plurality of second patterns 102 When the stylus pen driving signal is applied to the , the uplink signal is relatively larger than when the stylus pen driving signal is applied to the plurality of first patterns 101 .

This is because the other ends of the plurality of second patterns 102 are electrically connected, so when two or more second patterns to which the stylus pen driving signal is applied are appropriately selected, at least one current loop is formed, but the plurality of first patterns 102 are electrically connected to each other. This is because the other ends of (101) are not electrically connected to each other, so a current loop cannot be formed. When current flows through each first pattern 101, the RC of each first pattern 101 is charged, so the current does not flow well from one end of each first pattern 101 to the other end. In addition, the stylus pen driving signal applied through the plurality of first patterns 101 is transmitted to the plurality of second patterns 101 in which a current loop is formed through capacitive coupling. In this case, the capacitive coupling This is because signal attenuation occurs.

Similarly, when the stylus pen driving signal is applied to the plurality of fourth patterns 104, the uplink signal is relatively larger than when the stylus pen driving signal is applied to the plurality of third patterns 103.

In <Table 2> above, 'downlink signal size' refers to the size of the stylus pen signal received from the stylus pen. When comparing the size of the signal by receiving the same stylus pen signal through a plurality of first patterns 101 and a plurality of second patterns 102, the stylus pen signal is received through a plurality of second patterns 102. In one case, the downlink signal is relatively larger than in the case where the stylus pen signal is received through the plurality of first patterns 101. The reason is that the other ends of the plurality of second patterns 102 are electrically connected to form a current loop, but the other ends of the plurality of first patterns 101 are not electrically connected to each other, especially, This is because the stylus pen signal is transmitted from the plurality of second patterns 101 in which a current loop is formed through capacitive coupling to the plurality of first patterns 101, thereby causing attenuation of the downlink signal.

Likewise, when a stylus pen signal is received through a plurality of fourth patterns 104, the downlink signal is relatively larger than when a stylus pen signal is received through a plurality of third patterns 103.

In <Table 2> above, 'stylus additional channel' means whether an additional channel must be configured for the stylus pen in addition to touch sensing. When using a plurality of second patterns 102 or/and a plurality of fourth patterns 104 for driving or sensing of a stylus pen, an additional channel is required (see 'Usage' in <Table 2>). (marked with '). On the other hand, when driving or sensing a stylus pen using a plurality of first patterns 101 and/or third patterns 103 for touch sensing, an additional channel is not required (indicated as 'none' in <Table 2> )do.

The control unit 500' may detect the touch position by processing the output voltage value. Here, the control unit 500' may cancel the display noise and LGM noise by subtracting the detection signal received from the 1b pattern 101b from the detection signal received from the 1a pattern 101a.

Here, to prevent capacitive coupling between the third patterns 103 and the fourth patterns 104, the control unit 500' controls the plurality of third patterns 103 and the fourth patterns 104. It can be controlled so that the same driving signal is applied to the pattern 104.

The control unit 500' may control driving signals output from each driving circuit unit connected to the plurality of second a and second b patterns 102a and 102b. For example, the control unit 500' controls the first driving circuit part to output a pulse signal of a predetermined frequency, controls the second driving circuit part to output no pulse signal, and controls the third driving circuit part to output the first driving circuit part. It can be controlled so that a pulse signal that is opposite to the pulse signal output from is output. In this case, a current loop is formed with the 2a and 2b patterns 102a and 102b electrically connected to the first driving circuit and the 2a and 2b patterns electrically connected to the third driving circuit. A magnetic field is generated by the formed current loop, and a nearby stylus pen may resonate and be driven by the magnetic field.

The control unit 500' may control pulse signals opposing each other to be output to any two driving circuit units among the plurality of driving circuit units electrically connected to the plurality of second a and second b patterns 102a and 102b. Accordingly, the control unit 500' can change and set the size or location of the current loop in various ways. For example, when the control unit 500' detects the position of a nearby stylus pen, the driving circuit unit electrically connected to the two second patterns around the position of the stylus pen can be controlled to output opposing pulse signals, , If the position of the stylus pen is not detected, a driving circuit electrically connected to the two 2nd a and 2b patterns (102a, 102b) located on the outermost sides of the plurality of 2a and 2b patterns (102a, 102b). It can also be controlled so that pulse signals that conflict with each other are output.

Meanwhile, although not shown in a separate drawing, the control unit 500' may control the driving signal to be applied to a plurality of the 1st a pattern 101a, the 1b pattern 101b, and/or the third pattern 103. there is. In this case, there is an advantage in reducing the total number of channels.

Referring to FIGS. 30 and 27, in the stylus sensing mode, the control unit 500' controls the detection circuit for stylus sensing with the first a and first b patterns 101a and 101b and the third pattern (101a, 101b) of the sensor unit 100'. 103) can be electrically connected to each other.

In the stylus sensing mode, similar to the principle explained with reference to FIG. 21, when the stylus pen approaches a random position of the sensor unit 100', a predetermined signal is output from the stylus pen, and the output signal causes the first a, An induced voltage is generated in the 1st b, 2a, 2b, 3rd, and 4th patterns 101a, 101b, 102a, 102b, 103, and 104.

Here, when the stylus pen is located far away from the control unit 500', due to the generation of induced voltage, little current flows in the plurality of first a patterns 101a themselves, but the plurality of second a patterns 102a Since current flows in from , the control unit 500' can detect the position of the stylus pen through a sensing circuit unit electrically connected to the plurality of first a patterns 101a. Here, the current flowing from the 2a pattern 102a to the 1st a pattern 101a is because a potential difference equal to the induced voltage is generated between the 1a pattern 101a and the 2a pattern 102a, and the generated potential difference This is due to capacitive coupling between the first a pattern 101a and the second a pattern 102a.

Likewise, almost no current flows through the plurality of 1b patterns 101b themselves, but since current flows from the plurality of 2b patterns 102b, the control unit 500' operates between the plurality of 1b patterns 101b and The position of the stylus pen can be detected through an electrically connected sensing circuit.

Likewise, almost no current flows in the third pattern 103 itself, but since current flows in from the fourth pattern 104, the control unit 500' operates the stylus pen through a sensing circuit electrically connected to the third pattern 103. The location can be detected.

Meanwhile, although not shown in the drawing, unlike FIG. 30, the control unit 500' electrically connects the sensing circuit units to the plurality of 2a patterns 102a and 2b patterns 102b, or/and the fourth pattern 104. By connecting it, the position of the stylus pen can also be detected.

31 is a schematic diagram of a touch input device according to another embodiment of the present invention.

Compared to the sensor unit 100'' shown in FIG. 27, the sensor unit 100'' of the touch input device shown in FIG. 31 has 1 a, 1 b, 2 a, 2 b, third, and The structure of the 4 patterns is the same. The difference is that the 1b pattern located on one side (lower side) of the plurality of 1b patterns 101b electrically connected to each other along the first direction is electrically connected to the control unit 500'' and operates in the first direction. Accordingly, among the plurality of first a patterns 101a electrically connected to each other, the first a pattern 101a located on the other side (upper side) is electrically connected to the control unit 500''. At this time, among the plurality of 1b patterns 101b electrically connected to each other along the first direction, the 1b pattern located on the other side (upper side) is electrically open, and the plurality of 1b patterns 101b electrically connected to each other along the first direction are electrically open. Among the 1a patterns 101a, the 1a pattern 101a located on one side (lower side) is electrically opened.

FIG. 32 is a diagram illustrating a case where the touch input device shown in FIG. 31 operates in touch sensing mode (or 2D sensing mode).

The description of the touch sensing mode is the same as that described in FIG. 28, so it is omitted.

FIG. 33 is a diagram illustrating a case where the touch input device shown in FIG. 31 operates in antenna driving mode (or stylus driving mode, or stylus uplink mode).

The description of the antenna driving mode is the same as that described in FIG. 29, so it is omitted.

FIG. 34 is a diagram illustrating a case where the touch input device shown in FIG. 31 operates in stylus sensing mode (or stylus downlink mode).

The stylus sensing mode of FIG. 34 is different from the stylus sensing mode of FIG. 30.

When the stylus pen approaches a random position on the sensor unit 100'' and is driven to emit a signal from the stylus pen, a predetermined signal is output from the stylus pen, and the 1a, 1b, and 2a signals are output from the stylus pen. , induced voltages are generated in the second, third, and fourth patterns 101a, 101b, 102a, 102b, 103, and 104.

Here, when the stylus pen is located far away from the control unit 500', due to the generation of induced voltage, little current flows in the plurality of 1b patterns 101b themselves, but the plurality of 2b patterns 102b In addition, since current flows from the plurality of first a patterns 101a, the control unit 500' can detect the position of the stylus pen through a sensing circuit electrically connected to the plurality of first b patterns 101b. . Here, the current flowing into the 1b pattern (101b) from the 2b pattern (102b) and the 1a pattern (101a) is between the 1b pattern (101b) and the 2b pattern (102b) and the 1b pattern (101b). ) and a potential difference equal to the induced voltage is generated between the 1a pattern 101a, and capacitive coupling between the 1b pattern 101b and the 2b pattern 102b due to the generated potential difference and the 1b pattern This is due to capacitive coupling between (101b) and the first a pattern (101a).

Here, the reason why current flows from the 1a pattern 101a to the 1b pattern 101b is because, unlike FIG. 30, a relatively large amount of current flows through the plurality of 1a patterns 101a themselves. This is because the direction of the conductive trace connected to the plurality of 1a patterns 101a is opposite to the direction of the conductive trace connected to the plurality of 1b patterns 101b. In other words, when the stylus pen is located far away from the sensing circuit connected to the plurality of 1b patterns 101b, the stylus pen is located closer to the sensing circuit connected to the plurality of 1a patterns 101a. Because.

Likewise, almost no current flows in the third pattern 103 itself, but since current flows in from the fourth pattern 104, the control unit 500' operates the stylus pen through a sensing circuit electrically connected to the third pattern 103. The location can be detected.

Meanwhile, although not shown in the drawing, unlike FIG. 34, the control unit 500'' electrically connects the sensing circuit units to a plurality of 2a patterns 102a, 2b patterns 102b, or fourth patterns 104. By connecting it, the position of the stylus pen can also be detected.

The fifth pattern 105' may have a shape corresponding to the third pattern 103. For example, the fifth pattern 105' has a diamond shape and may have a diamond-shaped opening therein.

One part of the fifth pattern 105' may be arranged to overlap the third pattern 103 in the vertical direction, and the other part may be arranged to overlap the fourth pattern 104 in the vertical direction. For example, the outer edge portion of the fifth pattern 105' may overlap with the inner edge portion of the third pattern 103 disposed on another layer. The inner edge portion of the fifth pattern 105' may overlap the outer edge portion of the fourth pattern 104 disposed on another layer.

The fifth pattern 105' is electrically connected to the fourth pattern 104 disposed on another layer through a conductive via (v). Here, the number of vias (v) may be multiple and may be arranged at the outer edge of the fourth pattern 104.

It may overlap with the outer edge portion of the second pattern 102 disposed. Additionally, the sixth pattern (not shown) may be electrically connected to the second pattern 102 disposed on another layer through a conductive via. Likewise, this sixth pattern (not shown) can also form a mutual capacitance in a direction perpendicular to the first pattern 101, and the sixth pattern (not shown) is connected to the second pattern 102 and the inside of the first pattern 101. Because they are electrically connected, the first pattern 101 can eventually form a mutual capacitance (Cm) not only with the second pattern 102 but also with the sixth pattern (not shown).

As such, the sensor unit including a modified example of the fifth pattern 105' shown in FIG. 47 can form mutual capacitance in the vertical direction as well as the horizontal direction of the third pattern 103, and the sixth pattern 103 can form a mutual capacitance in the vertical direction.
