Description

[Technical Field]

[0001] FIELD OF THE DISCLOSURE This disclosure relates to pen and touch input systems. [Background technology]

[0002] Mobile phones, smartphones, laptop computers, digital Digital broadcasting terminals, PDAs (personal digital assistants), PMPs (portable multimedia ia player), navigation, slate PC, tablet PC ), Ultrabooks, and wearable devices Various touch input devices are equipped with touch sensors.

[0003] In such touch input devices, the touch sensor is connected to a display panel that displays an image. It can be located on the touch screen or part of the touch input device. Touch input devices provide intuitive user interaction by touching the screen. A user interface can be provided to the user.

[0004] Users can use a stylus pen for precise touch input. The Raspen is active (or not) depending on whether it has a battery and electronic components inside. Stylus pens can be divided into active and passive stylus pens.

[0005] Active stylus pens have superior basic performance compared to passive stylus pens, and additional It has the advantage of providing advanced functions (pressure, hovering, buttons), but the pen itself is expensive. However, since it requires a power source and requires charging the battery, it is difficult to actually use it except for some advanced users. The drawback is that there are not many users.

[0006] Passive stylus pens are cheaper than active stylus pens and require less battery power. It has the advantage of not requiring a touchpad, but it requires more precise touch recognition than an active stylus. However, recently, passive sensors that can precisely recognize touch have become available. To realize the ink pen, we used EMR (Electromagnetic Resonance) technology, which is an inductive resonance method. The technologies proposed are magnetic resonance and capacitive resonance. It has been done.

[0007] The EMR method has the advantage of writing / drawing quality, which is the core function of a stylus pen, but In addition to the resistive touch panel, a separate EMR sensor panel and EMR driver IC are not required. Therefore, the thickness is large and the cost is increased.

[0008] The capacitive resonance method is similar to the general capacitance touch sensor and touch controller. Using a laser IC eliminates additional costs, and the performance of the IC is improved to support pen touch. This is the method.

[0009] In the EMR or capacitive resonance type, the touch sensor is To more accurately distinguish between touches, the amplitude of the resonant signal must be large. Therefore, the frequency of the drive signal transmitted to the stylus pen is equal to the frequency of the resonator built into the stylus pen. However, the resonant frequency of the circuit is almost the same as that of the conventional EMR method or the capacitor method. With the active resonance method, even if the resonance frequency and the drive signal frequency match, there is no attenuation of signal transmission. As a result, many touch controllers are Despite years of attempts by controller IC vendors, they have yet to produce a sufficient output signal and are not yet ready for mass production. The reality is that there are no successful manufacturers.

[0010] Therefore, the EMR method or the capacitive resonant type that can produce the maximum output signal is How to design the internal resonant circuit and pen structure for manufacturing a stylus pen? This is a very important factor.

[0011] On the other hand, among passive stylus pens, EMR (Electro-Magnetic Resonance) type pens In the case of a pen, the digitizer transmits a magnetic signal to the pen, and then the digitizer The digitizer receives a resonance signal from the pen. It is a closely packed array of coils in which currents can be induced by magnetic signals to receive Such a digitizer can accommodate smaller and thinner touch input devices. There is also the problem that it is not possible to design flexibly.

[0012] On the other hand, conventional stylus pens require expensive pressure sensors to detect writing pressure. Therefore, it is difficult to measure the precise pressure of the pen. Summary of the Invention [Problem to be solved by the invention]

In the downlink, an electromotive force (V1 or Vemf) is generated in the sensor part of the touch screen 20. In other words, the coil inside the stylus pen and the sensor part of the touch input device are connected by a transformer. It works with a transformer.

[0069] Figure 1c illustrates the spacing between the + and - drive channels in the uplink. This is a drawing for clarification.

[0070] Referring to FIG. 1c, in the uplink, between the + drive channel and the - drive channel, The optimum spacing depends on the shape and position of the inductor inside the stylus pen. As a general design standard for a stylus pen, the spacing between the + drive channel and the - drive channel is It is preferable to widen the gap (4 mm) by at least one channel.

[0071] FIG. 1d shows another embodiment of a pen and touch input system including a stylus pen and a touch input device. FIG. 1 is a conceptual diagram illustrating an embodiment.

[0072] Referring to FIG. 1d, the touch input device 2 is foldable. The Raspen 10 touches the screen 20 of the foldable touch input device 2 in the vicinity thereof. Receives a signal output from the input device 2 or the touch screen 20, and You can send a signal to 0.

[0073] A rectangular foldable touch input device 2 or a touch screen 20 included therein In the member, the long side located on the left side of the plane is the first long side LS1, and the long side located on the right side is the second long side LS2. 2 long side LS2, the upper short side is the first short side SS1, and the lower short side is the second short side S I will refer to it as S2.

It bends along a predetermined folding direction based on the folding axis AXIS_F. That is, the foldable touch input device 2 can be moved based on the folding axis AXIS_F. As a guide, the folded and unfolded states are It may be possible for the state to be converted between the folded and unfolded states.

[0075] FIG. 2a is a diagram illustrating a signal transmission operation between a stylus pen and a touch input device. It is a surface.

[0076] Referring to FIG. 2a(a), the touch screen 20a includes a digitizer 29, a display The display panel 251 includes a sensor unit 21 and a window 22.

[0077] Among passive stylus pens, EMR (Electro-Magnetic Resonance) type pens In this case, the digitizer 29 outputs a magnetic signal B to the EMR type stylus pen 10a. When the magnetic signal B is transmitted, the resonant circuit included in the stylus pen 10a resonates with the magnetic signal B. Then, the digitizer 33 receives the resonated magnetic signal B from the stylus pen 10a. .

[0078] The digitizer 29 may be attached below the display panel 251 and may be connected to a conductive antenna. FPCB (Flexible Printed Circuit Board) with multiple loops and antenna It blocks the magnetic field generated by the antenna loop and blocks other electric fields when the antenna loop forms a magnetic field. Ferrite sheet that blocks eddy currents that may be generated in electrical elements and components ) is included.

[0079] The FPCB has multiple antenna loops to detect the position where the resonant signal is input. Each antenna loop is connected to at least one other antenna loop. This results in a thick FPCB. When the digitizer 29 is used, it is difficult to make the touch input device 2 thin and small.

[0080] Such a digitizer 29 is mounted on the foldable / flexible touch input device 2. When folding occurs, the FPCB attached to the region to be folded undergoes deformation. This may occur in wiring materials that form antenna loops by repeated folding. Stress is applied, which can eventually lead to damage to the wiring material. , and shields 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, and deformation occurs when the touch input device 2 is folded. They are prone to breakage and can be damaged by repeated folding.

[0081] Referring to FIG. 2a (b), the touch screen 20b includes a display panel 251 , a sensor unit 21, and a window 22.

[0082] In the case of the stylus pen 10 including the resonant circuit, the electrode (or pattern) of the sensor unit 21 is When a magnetic signal B is transmitted to the stylus pen 10, a resonant circuit included in the stylus pen 10 resonates with the magnetic signal B. Then, the electrodes (or patterns) of the sensor unit 21 The pen 10 can receive an input of a resonated electromagnetic signal (E and / or B). The electrodes (or patterns) of the sensor part 21 are made of a metal mesh with low resistance. When formed, magnetic signals from the stylus pen 10 can be detected.

[0083] Similarly, compared to the digitizer 29, the touch screen 20b converts magnetic signals into a stylus signal. No additional units or modules are required to transmit data to the Spen 10, so touch The screen 20b can be made thinner, which is advantageous in terms of manufacturing costs.

[0084] Referring to FIG. 2a(c), the touch screen 20c includes a loop coil 264, a It includes a spray panel 251 , a sensor unit 21 , and a window 22 .

[0085] In the case of a stylus pen 10 including a resonant circuit, the loop coil 264 is When a magnetic signal B is transmitted to the stylus pen 10, the resonant circuit included in the stylus pen 10 resonates with the magnetic signal B. Then, the electrodes (or patterns) of the sensor unit 21 are connected to the stylus pen 10. It can receive input of oscillated electromagnetic signals (E and / or B).

[0086] Compared to the digitizer 29, the loop coil 264 has a magnetic field for detecting the touch position. Since it does not receive electrical signal B, the wiring structure is simple and the touch screen 20c can be made thinner. This allows the touch input device 2 to be made thinner and smaller. 64 can be formed in various sizes and positions, so The lean 20c can also be applied to the foldable / flexible touch input device 2.

[0087] The loop coil 264 includes a substrate on which the antenna loop is located and a ferrite sheet. The antenna loop may be formed of a conductive material such as copper or silver. In addition to the substrate, it can be located on the same layer as the sensor unit 21. In this case, the antenna loop High transmittance materials such as metal mesh, ITO, graphene, silver nanowire, etc. The antenna loop may be formed of a conductive material that exhibits low impedance. The substrate may be located under the dough, in which case the substrate does not need to be included in the loop coil 264. stomach.

[0088] In the above, the sensor unit 21 has a number of electrodes (or patterns) for detecting touch coordinates. For example, the sensor unit 21 may include a plurality of sensors for detecting touch coordinates in the first direction. a plurality of first touch electrodes and a plurality of second touch electrodes for detecting touch coordinates in a second direction intersecting the first direction; In FIG. 2, the sensor unit 21 is shown as a single layer. The first touch electrode and the second touch electrode may be located on different layers, The first touch electrode and the second touch electrode may be overlapped with each other, or may not be overlapped with each other. An additional layer may be interposed between the touch electrode and the substrate, but the present invention is not limited thereto.

[0089] Referring to FIG. 2a (d), the touch screen 20d includes a display panel 251 , a sensor unit 21, and a window 22.

[0090] In the case of an active stylus pen 10' including a resonant circuit, the active stylus pen 1 The resonant circuit included in the active stylus pen 10' is connected to a power supply (e.g., Batteries (including secondary batteries) and EDLC (electric double layered capacitors) for storage The sensor unit 21 uses a capacitor such as a capacitor to resonate. receives the input of the resonated electromagnetic signal (E and / or B) from the stylus pen 10'. The electrodes (or patterns) of the sensor part 21 are formed from a metal mesh with low resistance. When the active stylus pen 10' is turned on, it is possible to detect a magnetic signal from the active stylus pen 10'. The Eraser Pen 10' uses a power source as well as a resonant circuit to generate an electromagnetic signal. The device may include a circuit for outputting an electromagnetic signal (E and / or B) having a certain frequency. The active stylus pen 10' generates an electromagnetic signal (E and / or E) having a predetermined frequency through a resonant circuit. or B).

The drive signal can resonate with the resonant frequency of the resonant circuit section 12. The signal may include a signal having a corresponding frequency (e.g., a sine wave, a square wave, etc.). Therefore, the resonant frequency of the resonant circuit section 12 and the frequency of the drive signal are the same or very similar. The resonance frequency of the stylus pens 10a and 10b must be The design values ​​of the resonant circuit unit 12 of FIG. 2(b) or FIG. 2(c) are based on the design values ​​of the resonant circuit unit 12 of FIG. When the loop coil 264 in (c) generates an electromagnetic field due to a drive signal, the stylus pen 1 The resonant circuit sections 12 of the antennas 0a and 10b resonate using the signals received via changes in the magnetic field.

[0131] The inductance and / or capacitor of the inductor section 14 included in the resonant circuit section 12 If the capacitance of 13 is changed, the resonant frequency of the resonant circuit section 12 is changed. That is, when writing pressure is applied to the stylus pen 10, the resonance frequency of the resonance circuit unit 12 is changed. Therefore, the frequency of the electromagnetic field (electromagnetic force) output from the stylus pen 10 is changed.

It is okay to do so.

[0133] As shown in FIG. 4(a), the EMR type stylus pen 10a includes a resonant circuit section 12. The resonant circuit section 12 includes an inductor section 14 and a capacitor section 13. 14 is a ferrite core 115 and a coil 11 wound on the outer surface of the ferrite core 115. Includes 6.

[0134] The EMR type stylus pen 10a may further include a tip 11a. a is the tip of the stylus pen 10a, and is made of ferrite as shown in FIG. The ferrite core 115 may be disposed so as to penetrate the ferrite core 115, and the ferrite core 115 may be disposed so as to protrude from the ferrite core 115. The tip 11a may be a non-conductor or may be a conductor, for example, a conductive gold.

Alternatively, the ferrite core 115 may have a cylindrical shape, a multi-shaped shape, or the like.

[0142] FIG. 5 specifically illustrates the inductor portion of the stylus pen shown in FIGS. 4(a) and 4(b). This is a conceptual diagram.

[0143] Referring to FIG. 5, the inductor section 14 includes a ferrite core 115 and a ferrite core 116. 15 includes a wound coil 116.

[0144] At this time, the inductance of the inductor unit 14 is calculated by the following equation 1: It is determined by Equation 1

[0145] As can be seen from <Equation 1>, the inductance (L) is determined by the permeability of the ferrite core 115. It is proportional to the power of the permeability, the cross-sectional area of ​​the coil 116, and the number of turns of the coil 116. is inversely proportional to the length of the winding.

[0146] In the resonant circuit unit 12 housed in the stylus pen shown in (a) and (b) of FIG. Therefore, the design of the inductor section 14 is very important. As shown in Figure 6, the inductance (L) and Q factor are very important parameters. Here, the Q value is a quantity that indicates the coil characteristics as a resonant circuit element, and is expressed as follows: JPEG2025166047000003.jpg1338 where L and R are the inductance and resistance of the coil respectively, and f is The higher the Q value of a coil, the sharper the resonance characteristics can be obtained.

[0147] In the design of the stylus pen shown in Fig. 4(a) and (b), L is the length to be used. The self-resonance frequency must be large enough relative to the frequency of the It is preferable that the Q value has a maximum value at the frequency to be used. To achieve this, the ferrite core material, the coil wire type, and the winding scheme must be considered. ) must be optimized to obtain a high output signal while maintaining a thin pen diameter. There needs to be a way to do this.

[0148] In the following embodiments, various ferrite core materials, coil wire types, and winding methods are used. Explain the most optimized stylus design method among (winding scheme) .

[0149] (1) Ferrite core material The material of the ferrite core used in this embodiment is manganese (Mn), nickel (Ni) was used.

[0150] (2) Wire type The types of coil wire used in this embodiment were enameled wire and Litz wire. .

[0151] As shown in FIG. 7, the enameled wire 100 is made of a copper wire 101 coated with an insulating enamel 102. It is an electric wire made by covering it with a material and heating it at high temperatures, and is used in electrical equipment, communication equipment, electric meters, etc. In this embodiment, the total thickness (T) is 0.2 mm, and the wire diameter is An enameled wire with a diameter (Φ) of 0.18 mm and a coating thickness (t) of 0.01 mm was used.

[0152] As shown in FIG. 8, the Litz wire 200 is a thin insulated wire with a diameter of about 0.1 mm. Twist together several wires 100 (for example, enameled wire) to make one, and then apply nylon or other The Litz wire 200 is a special insulated wire with an insulating coating 201. This reduces the skin effect and is used in coils of high frequency circuits.

[0153] In this embodiment, the overall thickness (T) is 0.2 mm, the wire diameter (Φ) is 0.06 mm, and the A Litz wire with a sheath thickness (t) of 0.007 mm was used.

[0154] (3) Winding method In the embodiment of the present invention, sufficient inductance is achieved in the limited space of a stylus pen. In order to obtain a sufficient value (i.e., a sufficient number of windings), a winding method with a multi-layer winding structure is used. Specifically, as shown in Figure 9 (A) and (B), two types of multi-layer A winding method was used.

[0155] The winding method in Figure 9(A) is the simplest winding method, and once the winding of the lower layer is completed, the winding of the layer immediately above it is completed. This is a sequential layer winding scheme. In the (A) method of 9, the winding of the layer immediately above begins where the winding of the previous layer ends. Hereinafter, this will be referred to as the U-type winding method.

[0156] The winding method shown in FIG. 9(B) is a method in which adjacent winding layers are alternately wound (alternate layer). r winding scheme), in which the windings of adjacent layers are wound in a zigzag pattern Hereafter, this is called the zigzag type winding method. Specifically, the winding of the first layer After winding the second layer on the wire, the third layer is wound between the first and second layer windings. The fourth layer is wound on top of the second layer, and then the fifth layer is wound on top of the second layer. This zigzag type winding method is used to wind the wires between adjacent windings. The voltage difference between the windings of the layers can be minimized, and the winding self-capacitance can be reduced. The advantage is that it can reduce the parasitic capacitance. The winding self-capacitance, a type of capacitance, is the electric field energy (elec is a parameter indicating the tric field energy.

[0157] Comparative experiment 1 (comparison of characteristic values ​​by material) The coil wire type is enameled wire, and the winding method is U-type. The Q value was measured by changing the material of the tocoa to manganese, nickel, and magnesium.

[0158] As a result of the measurement, there was almost no difference in the Q value characteristics of each core material, and the measured Q value was also The level was far below what we could have achieved.

[0159] Comparison experiment 2 (comparison of characteristic values ​​by winding type) The ferrite core is made of manganese (Mn) and wound using a U-type winding method. Inductor 1 and Inductor 2 were made using enameled wire and Litz wire, respectively. The Q value of Kuta 2 was measured.

[0160] Figure 8 shows the frequency change via the Keysight Technologies E4980A precision LCR meter. 10 is a graph showing the Q values ​​of inductors 1 and 2 measured by the method described above.

[0161] In Figure 10, a is inductor 1 (manganese core / enamel wire / U-type winding method) ) is a waveform showing the change in Q value with respect to frequency, and b is the This is a waveform showing the change in Q value with frequency for a litz wire / U-type winding method.

[0162] Inductor 2 made from Litz wire has a Q of 0.01 at a frequency of around 400 kHz (frequency f1). The value was almost the maximum value, and inductor 1 made of enameled wire, the frequency was around 150 kHz. The Q value reaches almost its maximum value at wave number (frequency f2).

[0163] Comparing Figure 10a and b, the maximum Q value of inductor 2 is higher than that of inductor 1. Therefore, the resonant circuit of the stylus pen is It can be seen that Litz wire is superior to enameled wire for use as an inductor coil.

[0164] However, the maximum Q value of inductor 2 measured in comparative experiment 2 was also below the target value (Qt This was only about half the level of the target.

[0165] Comparison experiment 3 (comparison of characteristic values ​​by winding method) With the ferrite core material changed to manganese (Mn), the wire type was changed to enameled wire and Inductors 3 and 4 were manufactured using tipped wire with U-type and zigzag winding methods. The Q value of inductor 5 was measured.

[0166] Figure 11 shows the results of changing the frequency through a Keysight Technologies E4980A precision LCR meter. 10 is a diagram showing the further measured Q values ​​of inductors 3 to 5.

[0167] In Figure 11, a is inductor 3 (manganese core / enamel wire / U-type winding method) ) is a waveform showing the change in Q value with respect to frequency, and b is the waveform of inductor 4 (manganese core / This is a waveform showing the change in Q value with respect to frequency (enameled wire / zigzag type winding method), c is the frequency of inductor 5 (manganese core / litz wire / zigzag type winding method) 1 is a waveform showing the change in the Q value.

[0168] As can be seen from the waveform c in Figure 11, the inductor manufactured using the Litz wire / zigzag winding method In the case of 5, the Q value reaches its maximum value at a frequency of around 300 kHz (frequency f3). Inductor 4 manufactured using wire / zigzag winding method and inductor 5 manufactured using enameled wire / U-type winding method Inductor 3 exhibits a maximum Q value at a frequency of approximately 150 kHz (frequency f2). vinegar.

[0169] In addition, by comparing a, b, and c in Figure 11, the maximum Q value of inductor 5 is This is about 1.5 times higher than the maximum Q value and more than twice the maximum Q value of inductor 3. Therefore, the winding method of the inductor that forms the resonant circuit of the stylus pen is ,It can be seen that the zigzag type winding method is superior to the U type winding method.

[0170] However, the inductor 5 (manganese core / litz wire / zigzag tube) measured in the comparative experiment 2 The target value (Q target) required for commercialization of the 1000V coil winding method was only about 3 / 4 of the target value. .

[0171] Comparative experiment 4 (comparison of characteristic values ​​by core material) In this embodiment, manganese and nickel are used as the material for the ferrite core. The magnetic permeability of iron is known to be 200-300, while that of manganese is known to be 3000-5000. are.

[0172] The manganese used in this embodiment has a magnetic permeability about 15 times higher than that of nickel, so the coil Assuming that the cross-sectional area and length of the The advantage is that the number of windings of the nickel alloy can be reduced by about four times compared to the number of windings of the nickel alloy. Therefore, from the viewpoint of the number of windings alone, it is more effective to use manganese than nickel. We can see that.

[0173] On the other hand, the inductor section 14 has a complex structure including a coil wound around a core. , additional parasitic capacitances are formed. These parasitic capacitances cause the Q As the value decreases, there is a problem of reducing the amplitude of the resonant signal.

[0174] The parasitic capacitance formed in the inductor section 14 is between the wound coil and the core. This can occur between the coil and the wire, but as mentioned above, by adopting a zigzag type winding method, This reduces the parasitic capacitance between the wound coils.

[0175] On the other hand, in this embodiment, in order to reduce the parasitic capacitance between the core and the coil, The core material was tested to have a lower dielectric constant than nickel. It was confirmed that this is the optimum material for the light core.

[0176] Important physical properties of manganese and nickel, which are primarily used as ferrite core elements The property is the permeability, which is the inductance value as shown in Equation 1. However, in the case of manganese and nickel as ferrite elements, The permittivity is a physical property of little interest, and in fact the In some cases, the relevant information is even missing from the data sheets provided by the manufacturers.

[0177] In this embodiment, in order to check the dielectric constant of manganese and nickel, KEYSIGHT TECHNOGIE Using S company's E4980A precision LCR meter, the permittivity of manganese and nickel was measured. The results are shown in Table 1 below. [Table 1]

[0178] Measurements 1 and 2 were performed using the same Keysight Technologies E4980A precision LCR meter. Measurement 1 was performed using the dielectric constant automatically calculated by the measurement software. According to measurement 1, the dielectric constant of manganese is 2400, but the dielectric constant of nickel is It turns out that this will not be the case.

[0179] Measurement 2 measures the capacitance, area, and distance between the ferrite cores to calculate the dielectric constant According to the method used, the dielectric constant of manganese is 8300, and that of nickel is The electrical conductivity was measured to be 2.

[0180] There is a large difference in the dielectric constant between measurement 1 and measurement 2, especially in measurement 2. It was confirmed that there was a considerable amount of error due to the persistence, area, distance, etc. However, measurement 1 and The results of measurement 2 show that the dielectric constant of nickel is at least 1 / 1000 smaller than that of manganese. We can see that.

[0181] In comparative experiment 4, the material of the ferrite core was changed to nickel and the wire type was changed to Litz wire. Inductor 6 and 7 were manufactured by changing the winding method to U type and zigzag type. The Q value of the inductor 7 was measured.

[0182] Figure 12 shows the results of changing the frequency through the Keysight Technologies E4980A precision LCR meter. 10 is a diagram showing further measured Q values ​​of inductors 6 and 7.

[0183] In Figure 12, a is inductor 6 (nickel core / litz wire / U-type winding method) is a waveform showing the change in Q value with respect to frequency, and b is the waveform of inductor 7 (nickel core / ribbon) This is a waveform showing the change in Q value with frequency for a 1000V AC / 1000V DC power supply (Zigzag type winding method).

[0184] As can be seen from the waveform in Figure 12b, it is manufactured using a nickel core / Litz wire / zigzag winding method. Inductor 7, the Q value reaches almost its maximum value at a frequency of around 400 kHz (frequency f5). Inductor 6, which was manufactured using a nickel core / Litz wire / U-type winding method, had a resistance of 200 The Q value reaches its maximum value at a frequency of around 1000 kHz (frequency f6). As a result, it was found that the maximum Q value of inductor 7 was approximately twice as high as that of inductor 6. I understand.

[0185] On the other hand, inductor 7 (nickel core / litz wire / zigzag tie) measured in comparative experiment 4 It was found that the maximum Q value of the MOSFET (winding method) almost reached the target value (Qtarget) required for commercialization. It was.

[0186] In the comparative experiments 1 to 4 described above, the material of the ferrite core, the type of wire of the coil, Q value is determined by changing the combination of the type and winding scheme. As a result of the test, the nickel core, Litz wire, zigzag type winding method was used. Obtaining the highest Q factor when designing the inductor part of a passive resonant stylus pen The maximum Q value of the inductor manufactured using this combination is: It was found that the target value for commercialization (Qtarget) was reached.

[0187] On the other hand, in this embodiment, a nickel core is used as the ferrite core, and the wire of the core The experiment was conducted using Litz wire as the type, but in addition to the nickel core, ferrite cores were also used. Use a material with a dielectric constant of 1000 or less, and one coil has two or more insulators other than Litz wire. Similar results can be obtained when using wires wrapped around strands. I guess so.

[0188] Hereinafter, the touch input device in the pen and touch input system according to the embodiment of the present invention will be described. Before going into detail about the placement of the stylus, let us first consider the different positions of the stylus on the touchscreen. Explain why the output voltage (Vout) of the CVA (Capacitor Voltage Amplitude) changes .

[0189] FIG. 13 shows the CVA (Ca) depending on the position of the stylus pen 10 on a conventional touch screen. This is a schematic diagram to explain how the output voltage (Vout) of a This is a drawing.

[0190] Referring to FIG. 13, the CVA is determined depending on the position of the stylus pen 10 on the touch screen. The reason for the different outputs is that the stylus pen 10 is located on both sides of the sensing line. The reason is that the impedance ratio of

[0191] Based on the long axis of a conventional touch screen, the metal mesh touch sensor The resistor (R) is approximately 1.2 kΩ, and the capacitor (C) is approximately 250 pF.

[0192] Based on 10 distributed models, the capacitance is The impedance of the capacitor is about 200 times that of the resistor (120 ohms vs .1 / (2π*300k*25pF)=21k(ohm)). Therefore, the capacitor is the main This is the cause.

[0193] FIG. 14 shows the output voltages (Vout1, Vo) of the CVA depending on the position of the stylus pen 10 in FIG. To explain the difference between the current sensing and the current sensing 15 shows the output voltage of the CVA according to the position of the stylus pen 10 in FIG. 13. (Vout1, Vout2) are different through voltage sensing 1 is a diagram for explanation.

[0194] 14 and 15, depending on the position of the stylus pen 10 on the sensing line, The output voltage of the VA is different. That is, the closer the stylus pen 10 is to the sensing circuit unit 50, The output voltage of the CVA is large, and the output voltage of the CVA decreases as it moves away from the sensing circuit unit 50. It becomes.

[0195] Hereinafter, touch input devices according to various embodiments of the present invention will be described in detail with reference to the accompanying drawings. will be explained.

[0196] FIG. 16 is a schematic diagram showing the structure of a sensor unit 100 of a touch input device according to a first embodiment of the present invention. This is a diagram.

[0197] The touch input device according to the first embodiment of the present invention is a portrait type touch input device. Such a portrait-type touch input device may be a wide, high-resolution touch input device. The control unit (not shown) that controls the sensor unit 100 is located below the sensor unit 100. For example, such a touch input device may be configured to correspond to the shape of a smartphone. .

[0198] The sensor unit 100 is capable of detecting the position of an object such as a finger placed on the screen. Instead, the stylus pen 10 shown in FIG. 1a positioned on the screen can be driven. , detects the signal (stylus pen signal) emitted from the stylus pen and displays it on the screen The position of the stylus pen can be detected.

[0199] The sensor unit 100 includes a large number of patterns (or a large number of electrodes).

[0200] The sensor unit 100 has a number of first to fourth patterns 101, 102, 103, and 104. It may include.

[0201] The first pattern 101 has a shape extending along an arbitrary first direction y. The first pattern 101 may be in the direction of the long axis of the screen of the touch input device. The first pattern 101 may be named as an electrical path along an arbitrary first direction y. The channel may have a predetermined shape.

[0202] The second pattern 102 has a shape extending along the first direction y, and is The second pattern 101 is disposed adjacent to the first pattern 101 and is spaced a predetermined distance apart. The second pattern 102 may also be named DTX (Dummy TX). 101 and may have a predetermined shape in which an electrical path is formed along the first direction y.

[0203] The third pattern 103 has a shape extending along a second direction x that is different from the first direction. The second direction x may be perpendicular to the first direction y and may be in the direction of the minor axis of the screen of the touch input device. The third pattern 103 may also be named ARX (Active RX). The turn 103 has a predetermined shape in which an electrical path is formed along an arbitrary second direction x. good.

[0204] The fourth pattern 104 has a shape extending along the second direction x, and is The fourth pattern 102 is arranged adjacent to the third pattern 103 and is spaced a predetermined distance apart from the third pattern 103. The fourth pattern 104 may also be named DRX (dummy RX). 03 and may have a predetermined shape in which an electrical path is formed along the second direction x.

[0205] The third and fourth patterns 103 and 104 are disposed on the first and second patterns 101 and 102. The first and second patterns 101 and 102 are disposed at a predetermined distance from each other. The sensor portion in which the first to fourth patterns are arranged on the same layer will be described in detail with reference to FIG.

[0206] The plurality of first patterns 101 are arranged along the second direction x, and the plurality of second patterns 102 The third patterns 103 are also arranged along the second direction x. A large number of fourth patterns 104 are also arranged along the first direction y.

[0207] The first pattern 101 extends along the first direction y, and the third pattern 103 extends along the second direction x. Since the first direction y is longer than the second direction x, the number of first patterns 101 is large. The number of the third patterns 103 is smaller than the number of the first patterns 101. The number of channels is less than the number of channels of the third pattern 103 .

[0208] Here, the number of the multiple first patterns 101 and the number of the multiple third patterns 103 are It may increase or decrease depending on the size of the screen of the input device.

[0209] The second patterns 102 correspond one-to-one to the first patterns 101, and have the same individual patterns. The other end (or second side end) of each of the multiple second patterns 102 may be , are electrically connected to each other through the conductive pattern. It may be Metal Mesh or Silver Trace.

[0210] One end (or a first side end) of the second patterns 102 is electrically connected to a control unit (not shown). Here, as shown in FIG. 17, a number of second patterns 102 may be connected. One end of each of the two or more second patterns 102 may be electrically connected via a conductive pattern. With this configuration, the number of channels in the multiple second patterns 102 is larger than the number of channels in the multiple first patterns 102. The number of channels in the second pattern 102 may be reduced to half of the number in the first pattern 101. The two or more second patterns 102 may be adjacent to each other.

[0211] On the other hand, as shown in FIG. 18, each of the ends of the second patterns 102 is individually They may be connected to one conductive pattern.

[0212] Referring again to FIG. 16, a large number of third patterns 103 are arranged along the first direction y. Therefore, the number of the multiple third patterns 103 is greater than the number of the multiple first patterns 101. Therefore, the number of channels in the third pattern 103 is equal to the number of channels in the first pattern 101. More than the number of channels.

[0213] The fourth patterns 104 correspond one-to-one to the third patterns 103, and have the same individual patterns. The other end (or second side end) of each of the multiple fourth patterns 104 may be , are electrically connected via the conductive pattern.

[0214] In the sensor unit 100 of the touch input device shown in FIG. 16, a plurality of first panels The turn 101 and the numerous third patterns 103 are basically touches of a finger-like object. To this end, the first patterns 101 are applied with touch driving signals. The touch sensing signal is received by the third patterns 103. It can operate with the touch sensing electrodes (RX electrodes, or touch receiving electrodes) that receive the signal. Of course, it can also work the other way around.

[0215] The sensor unit 100 of the touch input device shown in FIG. 16 drives the stylus pen. ) and sensing (sensing), a number of first to fourth patterns 101, 10 2, 103, and 104 may be used in various combinations. In Table 2 below, "1" indicates a number of first patterns 101. , "2" represents a large number of second patterns 102, "3" represents a large number of third patterns 103, and "4" represents a large number of third patterns 103. indicates a number of fourth patterns 104. [Table 2]

[0216] Referring to Table 2 above, in various combinations (No. 1 to No. 32), many first The pattern 101 and the multiple third patterns 103 sense the touch of an object such as a finger. Specifically, the first patterns 101 are used as touch driving electrodes. The third pattern 103 acts as a touch receiving electrode, and the third pattern 104 acts as a touch receiving electrode. is also possible.

[0217] At least one of the first to fourth patterns 101, 102, 103, and 104 One or two of them act as a stylus driving electrode for driving a stylus pen. At least one of the first to fourth patterns 101, 102, 103, and 104 can be selected. One or two patterns are used to form a current loop for driving the stylus pen. For example, the X-axis drive can drive a number of first patterns 101 and a number of second patterns 102. 02, and the Y-axis drive is a number of third patterns 103 and a number of fourth patterns 10 4. The stylus pen can be driven either along the X axis or along the Y axis. Either is possible, or both are possible.

[0218] At least one of the first to fourth patterns 101, 102, 103, and 104 Or two, a sensor that senses the stylus signal emitted from the stylus pen. For example, it can be used to sense the signal of a stylus pen. To achieve this, both X-axis sensing and Y-axis sensing are required, so many first to fourth patterns are required. Two patterns from patterns 101, 102, 103, and 104 can be used. X-axis The sensing is either one of a number of first patterns 101 or a number of second patterns 102. The Y-axis sensing may be performed by detecting a number of third patterns 103 and a number of fourth patterns 104. It may be either one.

[0219] In Table 2 above, the "uplink signal magnitude" refers to the signal strength of the start signal in Figure 1a. It means the magnitude of the drive signal for driving the stylus 10. A driving signal is applied to each of the first patterns 101 and the second patterns 102. When comparing the magnitude of the signal received by the stylus pen, it is found that there are many second patterns 102. When the stylus pen driving signal is applied, the stylus pen is applied to the first pattern 101. The uplink signal is relatively larger than when the drive signal is applied.

[0220] This is because the other ends (or second side ends) of the second patterns 102 are electrically connected. By appropriately selecting two or more second patterns to which the stylus pen drive signal is applied, At least one current loop is formed, but the other end of the first pattern 101 (or the second end) are not electrically connected to each other, so no current loop can be formed. When a current flows through each first pattern 101, the RC of each first pattern 101 becomes Since the charging occurs, one end (or the first side end) of each first pattern 101 The current does not flow well from the first end to the other end (or the second end). The stylus pen driving signal applied through the first pattern 101 is a capacitive capacitive The current is transmitted to a number of second patterns 102 in which current loops are formed via couplings. This is because at this time, signal attenuation occurs due to capacitive coupling.

[0221] Similarly, when a stylus pen driving signal is applied to a number of fourth patterns 104, a number of When the stylus pen drive signal is applied to the third pattern 103, the uplink signal is Relatively larger.

[0222] In Table 2 above, the "downlink signal magnitude" refers to the signal strength of the signal shown in Figure 1a. It means the magnitude of the stylus signal received from the stylus pen 10. The Raspberry Pi signal is transmitted through a number of first patterns 101 and a number of second patterns 102. When the received signals are compared in magnitude, the stylus is detected through a number of second patterns 102. When a pen signal is received, the stylus pen signal is received through a plurality of first patterns 101. The downlink signal is relatively louder than when received.

[0223] The reason is that the other ends (second side ends) of the second patterns 102 are electrically connected. A current loop is formed between the first patterns 101 and the other end (first side end) of the first patterns 101. are not electrically connected to each other, and in particular, current flows through capacitive coupling. The stylus pen signals are transferred from the second patterns 102 in which the loops are formed to the first patterns 103. This is because the downlink signal is transmitted to the node 101, and at this time, attenuation of the downlink signal occurs.

[0224] Similarly, when a stylus pen signal is received via a number of fourth patterns 104, When the stylus pen signal is received via the third pattern 103 of the number of downlink signals, The number is relatively larger.

[0225] In the above table 2, "Stylus additional channel" refers to the touch-sensing This means that you must configure an additional channel for the stylus pen in addition to the A number of secondary ports are used for driving and sensing the stylus pen. If turns 102 or / and multiple fourth patterns 104 are used, additional channels may be required. On the other hand, the driving and sensing of the stylus pen are A plurality of first patterns 101 and / or third patterns 103 for touch sensing are provided. If used, no additional channel is required (shown as "none" in Table 2).

This means that the other ends (second side ends) of the plurality of fourth patterns 104 are electrically connected to each other. The fourth patterns 104 are simply connected to one end (first side end) of the fourth patterns 104. It can mean that there is no

The fourth pattern 104 is used separately as a stylus driving electrode and a stylus sensing electrode. It is used separately as a driving electrode and a stylus sensing electrode, so it can drive and sense the stylus pen. An additional channel is required for the signaling.

A stylus sensing electrode is used as a driving electrode and is used to sense a stylus pen signal. The third patterns 103 are used as poles for touch sensing of the object. and a stylus pen signal sensing electrode. The second and fourth patterns 102, 104 are used as the image sensing electrodes. becomes electrically floating.

[0236] In the case of No. 13, a large number of first patterns 101 are used as stylus driving electrodes. , the magnitude of the uplink signal is relatively small. Since the pattern 103 is used as a stylus sensing electrode, the magnitude of the downlink signal is relatively small. The first patterns 101 are relatively small.

Such a landscape type touch input device has a high width and The height of the sensor unit 100' is larger than that of the sensor unit 100', and a control unit (not shown) that controls the sensor unit 100' is located below the sensor unit 100'. For example, such a touch input device may be configured to correspond to the shape of a tablet PC. It is possible.

[0253] The configuration of a sensor unit 100' of a touch input device according to a second embodiment of the present invention is shown in FIG. The configuration is the same as that of the sensor unit 100 of the touch input device according to the first embodiment, and the direction is It is the same as rotating it 90 degrees.

[0254] The sensor unit 100' of the touch input device according to the second embodiment of the present invention includes a plurality of first to second electrodes. The fourth pattern includes 101, 102, 103, and 104. The first pattern includes 101 and the second pattern includes 102, 103, and 104. The first and second patterns 102 are arranged adjacent to each other and have a shape extending in one direction. The turn 101 and the second pattern 102 are a predetermined pattern in which an electrical path is formed along one direction. The third pattern 103 and the fourth pattern 104 are arranged adjacent to each other. , and has a shape extending along a direction different from the one direction. The fourth pattern 104 has a predetermined shape in which an electrical path is formed along the other direction. The other ends (second side ends) of the second patterns 102 may be electrically connected to each other. The other ends (second side ends) of the fourth patterns 104 are also electrically connected to each other.

[0255] The sensor unit 100' of the touch input device according to the second embodiment shown in FIG. The screen size of a tablet PC is about 10 to 14 inches, and the In the case of the example No. 1 in Table 2, the total channels of the sensor unit 100' are The number of trace channels (TX Trace Channels) and the number of drive trace channels (TX Trace Channels) can be roughly summarized as follows: , as shown in Table 3 below. [Table 3]

[0256] In the above Table 3, the number of channels of Stylus TX is a number of the first pattern 101. This means that the number of second patterns 102 is equal to the number of first patterns 103. Although the number of patterns is the same as that of the first pattern 101, as shown in FIG. The first end of the 02 is electrically connected to two adjacent ends of the 02. This is due to the number of channels being cut in half.

[0257] In the above table, the number of TX Trace channels is the number of Finger TX channels and Stylus The number of TX Trace channels is the total number of TX channels. This is the primary factor that determines the width of the bezel of the force device. In the touch input device according to the second embodiment, a control unit (not shown) controls the sensor unit 100' The fewer the number of TX Trace channels, the , the thickness of the width direction bezel of the touch input device can be reduced.

[0258] On the other hand, the screen size of the touch input device shown in Figure 19 is the same as that of a smartphone. For example, if the screen is 6.9 inches, there is no problem. The device screen size is 11 inches or 12.9 inches, which is the same as the screen size of a tablet PC. When the thickness of the sensor unit 100' is increased, the first to fourth patterns 101, 102, 103 of the sensor unit 100' are 3 and 104 are also longer, so the resistance and capacitance of the sensor part 100' are increased. The increase in the resistance and capacitance values ​​is A touch driving signal applied to any one of the patterns used as an electrode and a stylus In order to narrow the operating frequency bandwidth of the stylus driving signal for driving the pen, Therefore, there may be a problem that the required operating frequency bandwidth for the design cannot be obtained. To achieve this, it may be necessary to consider reducing the resistance and capacitance values ​​of the sensor unit 100'. However, there is a limit to how much this value can be reduced, and even if you reduce this value to the maximum, the above-mentioned problems will still occur. However, the problem cannot be solved.

[0259] Also, the stylus pen receives and inputs the stylus information to the control unit of the touch input device. The pen signal also attenuates as the sensor unit 100' becomes larger. The first to fourth patterns 101, 102, 103, and 104 are the farthest from the control unit. The stylus pen sensing signal at the position is attenuated in the process of being transmitted to the control unit, There is a problem in that the voltage value required for the design cannot be output.

[0260] The above problems are No. 3, 4, 7, 8, 11, 12, 15, 16, 1 in Table 2 above. As in the examples 9, 20, 23, 24, 27, 28, 31, and 32, a number of second patterns 10 2 is used as a stylus pen sensing electrode for sensing a stylus pen signal, No.2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24 in As shown in the examples of 26, 28, 30, and 32, a large number of fourth patterns 104 are generated as stylus pen signals. This can be solved by using the electrode as a stylus pen sensing electrode. In this example, a large number of second and fourth patterns 102 and 104 are magnetically guided by a stylus pen. In order to receive electromotive force directly through the second pattern 102 to the first pattern 101, Signal attenuation via capacitive coupling from pattern 104 to third pattern 103 There is no decline.

[0261] As a specific example, the sensor unit 100' of the touch input device according to the second embodiment may be The screen size of a scape-type tablet PC is approximately 10 to 14 inches. In the case of the example of No. 3 in Table 2 above, the total number of channels of the sensor unit 100' is The number of trace channels (TX Trace Channels) and the number of drive trace channels (TX Trace Channels) are listed below. This is as shown in Table 4. [Table 4]

[0262] In the above , the number of channels of Stylus TX is the same as the number of second patterns 102. This means that the number of the second patterns 102 is equal to the number of the first patterns 101. As shown in FIG. 21, each of the ends of the second patterns 102 is , which is due to the fact that each of the conductive patterns is individually connected to one conductive pattern.

[0263] In the above table, the number of TX Trace channels is the number of Finger TX channels and Stylus The number of TX Trace channels is the total number of channels on the minor axis of the touch input device. This is the main factor that determines the thickness of the bezel. The more it is reduced, the thinner the bezel can be on the minor axis of the touch input device.

[0264] The example in above has the disadvantage that the number of channels is slightly increased compared to above. , the number of the first patterns 101 is not transmitted through the number of the second patterns 102, but through the number of the stylus pen. In order to receive the pen sensing signal from the control unit, the voltage value of the stylus sensing signal received by the control unit is further increased. The applicant has found that the voltage of the stylus sensing signal received by the control unit It was confirmed through experiments that the value is about twice as large as that in Table 3.

[0265] In addition, since each of the multiple second patterns 102 is configured with one channel, multiple When the second pattern 102 is used as a stylus driving electrode (Stylus TX), The spacing between channels is reduced by half compared to example 3, improving the resolution of the stylus drive. There are advantages.

[0266] As another specific example, the sensor unit 100' of the touch input device according to the second embodiment may be The screen size of a landscape-type tablet PC is approximately 10 to 14 inches. In the case of the example of No. 8 in Table 2 above, the total number of channels (T The number of total channels and the number of driving trace channels (TX Trace Channels) are as follows: , as shown in Table 5 below. [Table 5]

[0267] In the above Table 5, the number of channels of Stylus TX is a number of the fourth pattern 104. This means that the number of fourth patterns 104 is equal to the number of third patterns 10 22, the number of the fourth patterns 104 is the same as that of the fourth patterns 104. Each of them is connected to a single conductive pattern.

[0268] In Table 5 above, the number of TX Trace channels is the same as the number of Finger TX channels. The number of TX trace channels determines the thickness of the bezel on the minor axis of the touch input device. The fewer the number of TX trace channels, the faster the tapping. The thickness of the bezel on the minor axis of the input device can be reduced.

[0269] The above has the disadvantage that the total number of channels is slightly increased compared to the example in above. However, the pen sensing signal is received from the stylus pen via a number of fourth patterns 104. Therefore, there is an advantage that the voltage value of the pen sensing signal received by the control unit becomes larger.

[0270] In addition, since each of the many fourth patterns 104 is made up of one channel, many When the fourth pattern 104 is used as a driving electrode (Stylus TX), Since the spacing between channels is reduced by half compared to the previous example, this has the advantage of improving the drive resolution.

[0271] Also, the number of TX trace channels can be reduced to 1 / 4 or 1 / 3 of the example in Table 3 above. This has the advantage of reducing the thickness of the width direction bezel B of the touch input device.

[0272] FIG. 23 is a schematic diagram showing a configuration of yet another example of the sensor unit 100′ shown in FIG. Figure.

[0273] The sensor unit 100'' in FIG. 23 has at least two first patterns 101'. The second patterns 101a and 101b are included. 02' includes at least two or more 2a patterns 102a and 2b patterns 102b. The multiple third and fourth patterns 103 and 104 are the same as those in the sensor unit 100 of FIG.

[0274] The pattern 1a 101a and the pattern 1b 101b are arranged in the same direction as the extension of the first pattern 101'. The second pattern 102a and the second pattern 102b are arranged along the second pattern. The electrodes are arranged along the extension direction of the coil 102'.

[0275] The other ends of the plurality of 2a patterns 102a are electrically connected to each other, and the plurality of 2b patterns 10 The other ends of the plurality of 2a patterns 102a and the plurality of 2b patterns 102b are electrically connected to each other. The other ends of the second b patterns 102b face each other.

[0276] At one end of the many 2a patterns 102a, two or more adjacent 2a patterns are connected to each other. One end of each of the second patterns 102b may be electrically connected to two or more adjacent second patterns 102b. The plurality of 2b patterns may be electrically connected to each other. One end of the second pattern 102a and one end of the second pattern 102b are connected to each other as shown in FIG. Each may be electrically connected to a conductive pattern individually.

[0277] As a specific example, the sensor unit 100'' shown in FIG. 23 is a landscape type. The screen size of a tablet PC is approximately 10 to 14 inches, and the N In the case of the example of o.1, the total number of channels of the sensor unit 100'' is The number of trace channels and the number of TX trace channels are summarized in Table 6 below. be. [Table 6]

[0278] In the above Table 6, the number of channels of Stylus TX is a number of the second patterns 102'. The number of the second patterns 102' is a value obtained by dividing the number by 2. This means that the number of the second patterns 102' is equal to the number of the first patterns 102'. The number of second patterns 102' is the same as the number of patterns 101', and the second patterns 102' are adjacent to each other. This is because the two second patterns are electrically connected to each other.

[0279] In the above table, the number of TX Trace channels is the number of Finger TX channels and Stylus The number of TX Trace channels is the total number of channels in the width direction of the touch input device. This is the main factor that determines the thickness of the bezel. The more it is reduced, the thinner the bezel can be on the minor axis of the touch input device.

[0280] The above has the disadvantage that the number of channels is slightly increased compared to the example in above. Since the length of each of the first pattern 101' and the second pattern 102' is reduced by half, the sensor part 1 The touch drive applied to the touch drive electrode by reducing the resistance and capacitance values ​​of 00'' The operating frequency bandwidth of the signal and the pen drive signal for driving the stylus pen can be widened. There is an advantage to being able to do this.

[0315] The operation mode of the touch input device 500 shown in FIG. 24 will now be described in detail. 24 is shown as example No. 1 in Table 2 above, so I will explain based on this. .

[0316] In the touch driving / sensing mode, the control unit 300 detects the touch of an object such as a finger. For position sensing, a number of driving circuit units 310 are connected to a number of first panels of the sensor unit 100A. The control unit 300 can electrically connect a number of switches to the switch 101A. By controlling the first pattern 101A, the conductive patterns connected to the first pattern 101A are connected to the driving circuit units. 310 can be electrically connected to the

[0319] Meanwhile, in the touch driving / sensing mode, a plurality of first patterns 101A and a plurality of second patterns Capacitive coupling occurs between turn 102A and In order to prevent this, the control unit 300 allocates a number of drive circuit units 310 to a number of second patterns 102A. At this time, the control unit 300 can electrically connect the first patterns 101. A drive signal identical to the drive signal applied to the second pattern 102A is applied to the second pattern 102B. Alternatively, the control unit 300 may control the driving of a plurality of first patterns 101A. When a signal is applied, a predetermined reference potential is applied to the second patterns 102A. It is also possible to control the voltage to be applied.

For example, the control unit 30 can control the drive signal (or pen drive signal) input. 0 indicates the first driving circuit among the plurality of driving circuit units 310 connected to the plurality of second patterns 102A. The second driving circuit section controls the output of a pulse signal of a predetermined frequency. The third driving circuit section controls the output of any pulse signal. An inverted pulse signal having a phase opposite to that of the pulse signal output from the first driving circuit is output. In this case, the second panel electrically connected to the first driving circuit unit A current loop is formed between the turn and the second pattern electrically connected to the third driving circuit unit. The formed current loop generates a magnetic field, which attracts the sensor unit 100A. The stylus pen may be driven.

[0322] The control unit 300 includes a plurality of driving circuit units electrically connected to the plurality of second patterns 102A. 310, so that two arbitrary driving circuit units output driving signals opposite to each other. Therefore, the control unit 300 can control the size and position of the current loop in various ways. For example, the control unit 300 may change the setting to a state close to the sensor unit 100A. When the position of the stylus is detected, two secondary patterns are created around the position of the stylus. and controlling the driving circuit unit to output opposite pulse signals. If the position of the stylus pen cannot be detected, a number of second patterns 1 A driving circuit part electrically connected to the two second patterns located on the outermost sides of O2A. It is also possible to control the outputs so that the pulse signals output from the outputs are opposite to each other.

[0323] FIG. 25 shows a state in which the control unit 300 of FIG. 24 drives a stylus pen on a number of second patterns 102A. 1 is a diagram illustrating a method of applying a pen driving signal for operating the pen. In FIG. 25, one second pattern 102A shown in FIG. 24 is simply indicated by one line Ch. Each line Ch corresponds to one channel.

[0324] As shown in FIG. 25, two adjacent second patterns are electrically connected to each other. In this configuration, two electrically connected The same signal is applied to the two patterns at the same time. It is composed of 42 channels, Ch0, Ch1, ..., Ch41, which are connected together.

[0325] For example, if the stylus pen 50 selects one of the 42 channels Ch0, Ch1, ..., Ch41, When the terminal is located between the second channel Ch2 and the third channel Ch3, the control unit 300 Based on the Raspberry Pen 50, one or more channels located on the second channel Ch2 side drive the pen. The stylus pen 50 is controlled to output a signal on the third channel Ch3 side. A pen driving signal having an inverted phase of the pen driving signal is outputted from one or more channels located at It can be controlled so that

[0326] In the stylus sensing mode (or the stylus downlink mode), the control unit 30 0 is a sensor part 100A including a plurality of sensing circuit parts 330 for stylus sensing. The first pattern 101A and the plurality of third patterns 103A can be electrically connected to each other. The control unit 300 controls a number of switches to generate a number of first patterns 101A and a number of The conductive pattern connected to the third pattern 103A is electrically connected to a plurality of sensing circuit units 330. can be linked to

[0327] The touch input device 500 according to the embodiment of the present invention has the following configuration: In the stylus sensing mode, a number of images can be captured depending on the position of the stylus pen on the sensor unit 100A. This has the advantage that the output voltage value of the sensing circuit unit 330 is hardly changed. The principle will be explained with reference to (a) to (f) of FIG.

[0328] 26(a) to 26(f) show the touch input device of FIG. 24 in stylus sensing mode. 1 is a diagram for schematically explaining the operating principle of a laser diode.

[0329] FIG. 26(a) shows one of the first patterns 101A shown in FIG. 24 and an electric 1 is a schematic modeling circuit diagram of a sensing circuit unit 330 of an electrically connected control unit 300. 26(b) shows a second pattern 101A disposed inside any one of the first patterns 101A. 26(c) is a circuit diagram that roughly models the pattern 102A. (a) is a voltage distribution graph for the circuit diagram of FIG. 26(d), and (b) is a voltage distribution graph for the circuit diagram of FIG. 26(b). 1 is a voltage distribution graph in a circuit diagram.

[0330] Referring to (a) and (c) of FIG. 26, the sensing circuit unit 330 is disposed on the first pattern 101A. If the stylus pen approaches any point A that is as far away as possible from the The voltage induced by the signal emitted from the stylus pen (Vemf, hereafter referred to as "induced voltage") If an induced voltage (Vemf) occurs at point A, looking to the left from point A, Since the equivalent capacitance of the first pattern 101A is small, the equivalent impedance is large. Therefore, the induced voltage (Vemf) is mostly applied to the left side of point A, The voltage on the right side of the A line is close to 0V, and almost no current flows. The voltage close to 0 (V) on the right side of the point gradually decreases due to the equivalent resistance of the first pattern 101A. Therefore, almost no voltage is applied to the input terminal of the sensing circuitry.

[0331] Referring to (b) and (d) of FIG. 26, if an induced voltage (Vemf) occurs at point A, On the left side of point A, the other ends of the second patterns 102A are electrically connected to each other. Looking to the left, the equivalent capacitance becomes larger, so the equivalent impedance approaches 0. Therefore, 0 (V) is applied to the left side of point A, and the second pattern 102 is applied to the right side of point A. Since one end of A is open, no voltage drop occurs at the equivalent resistance, and Vemf remains the same. It takes.

[0332] Comparing (c) and (d) of FIG. 26, the first pattern 101A and the second pattern 10 It can be seen that there is a potential difference of Vemf at any position between 2A and 1A. The potential difference of Vemf between the first pattern 101A and the second pattern 102A is The capacitive coupling between the first pattern 101A and the second pattern 102A The capacitive coupling causes the As shown, a current flows from the second pattern 102A to the first pattern 101A. The farther the position of the stylus pen is from the sensing circuit unit 330 of the control unit 300, the The current generated in the turn 101A itself gradually becomes smaller, but the current generated in the second turn 102A Since a current flows from the first pattern 101A to the control unit 300, The current output to the sensing circuit unit 330 is almost the same as the position of the pen. The control unit 300 detects the first pattern 101A through the sensing circuit unit 330 electrically connected to the first pattern 101A. The position of the stylus pen can be sensed.

[0333] As can be seen from (a) to (e) of Figure 26, point A is on the left or right side. Even if the pattern moves, the potential difference between the first pattern 101A and the second pattern 102A remains constant as Vemf. Therefore, the position of the stylus pen is detected on the sensor unit 100A. The control unit 300 receives the output from the sensing circuit unit 330 regardless of whether it is close or far from the sensing circuit unit. The stylus pen can be sensed from a constant signal that is output.

[0334] On the other hand, in the explanation of (e) of FIG. 26, the flow from the second pattern 102A to the first pattern 101A It has been explained that the current flowing through the conductor is due to capacitive coupling, but this is not the only explanation. For example, the current flowing from the second pattern 102A to the first pattern 101A is This is also possible by magnetic coupling.

[0335] The principles of (a) to (e) of FIG. 26 explained above are the same as those of any one of the third panels in the second direction. This also applies to the turn 103 and the fourth pattern 104. The same applies to the touch input device according to the first embodiment.

[0336] FIG. 26(f) shows a modeled version of the second pattern 102A shown in FIG. 26(b). 10 is a voltage distribution graph when the sensing circuit unit 330 is connected to the open terminal on the right side of the circuit diagram. That is, the voltage distribution graph in FIG. 26(f) shows that one end of the second pattern 102A is in the control 26(f) and 26(f) show the case where the sensing circuit unit 330 of the unit 300 is connected. Comparing (d) with (f) in Figure 26, the current decreases due to the equivalent resistance as you move to the right of point A. Therefore, in the case of (f) in Figure 26, the first pressure drop occurs as shown in (e) in Figure 26. The potential difference between the first and second patterns cannot be maintained as much as Vemf, and the second pattern Therefore, the current cannot be transferred to the first pattern. The further away it is, the less current is output from the first pattern. In the singular mode, one end of the second pattern 102A is left open and floating. It is preferable that:

[0337] The screen size of the touch input device shown in Figure 26 is the same as that of a smartphone screen, e.g. For example, if the screen size is 6.9 inches, there is no particular problem. The screen size is about 10 to 14 inches, which is the size of a tablet PC screen. When the capacitance of the sensor part 100A increases, the capacitance of the sensor part 100A also increases. The increase in the resistance and capacitance values ​​increases the resistance applied to the touch drive electrodes. Operating frequency band of the touch drive signal and the pen drive signal for driving the stylus pen The bandwidth is much narrower than that of a smartphone (6.9 inches). This results in a problem in that the required operating frequency bandwidth cannot be obtained.

[0338] In addition, the pen sensing signal received from the stylus pen is also increased due to the increase in the size of the sensor unit 100A. In particular, the part of the sensor unit 100A that is located farthest from the control unit 300 The pen sensing signal is attenuated during the process of being transmitted to the control unit 300, and the signal is attenuated to the extent required for the design. There is a problem in that the voltage value cannot be output.

[0339] The following describes a touch input device that can solve the above-mentioned problems.

[0340] FIG. 27 is a diagram showing a specific embodiment of the touch input device shown in FIG.

[0341] Referring to FIG. 27, a touch input device 500″ includes a sensor unit 100A″ and The sensor unit 100A'' may include a control unit 300 for controlling the sensor unit 100A''.

[0342] The sensor unit 100A'' has a number of first to fourth patterns 101A, 102A'', 1 103A, 104A, where a number of first, third and fourth patterns 101A, 10 3A, 104A are the first, third, and fourth patterns 101A, 102A, 103A, 104A shown in FIG. Since they are the same as 103A and 104A, the explanation thereof will be omitted.

[0343] Although the multiple second patterns 102A'' will be described below, the multiple second patterns 102A'' in FIG. For convenience, the description of the same parts as those in pattern 102A will be omitted.

[0344] Each of the second patterns 102A'' has one end (first side end) connected to a conductive pattern. Therefore, it may be electrically connected to the control unit 300. This portion is a plurality of second patterns in FIG. Different from 102A.

[0345] The other ends (second side ends) of the second patterns 102A'' are electrically connected to the conductive patterns. One end is relatively close to the control unit 300, and the other end is relatively It is far from Gobe 300.

[0346] The operation mode of the touch input device 500'' shown in FIG. 27 will now be described in detail.

[0347] In the touch driving / sensing mode, the control unit 300 detects the touch of an object such as a finger. For position sensing, a plurality of driving circuit units 310 are connected to a plurality of first electrodes of the sensor unit 100A''. The control unit 300 can electrically connect the plurality of switches to the pattern 101A. 101A to drive the conductive patterns connected to the first patterns 101A. 310 can be electrically connected to the

[0348] In addition, the control unit 300 has a plurality of sensing circuits 330 for sensing the touch position. The third patterns 103A of the sensor part 100A'' can be electrically connected to each other. The control unit 300 controls a number of switches to control a number of transmission lines connected to the third pattern 103A. The conductive pattern can be electrically connected to a number of sensing circuit units 330 .

[0349] In this touch driving / sensing mode, the control unit 300 controls a plurality of first patterns. The touch sensing drive signal (or touch drive signal) is simultaneously or The sensing signals (or touch sensing signals) received from the third patterns 103A are sequentially applied. A plurality of the control units 300 electrically connected to the plurality of third patterns 103A receive the signal. The sensing circuit converts the information on the capacitance change amount contained in the input sensing signal into a predetermined voltage. The control unit 300 processes the output voltage value to determine the touch position. can be detected.

[0350] Antenna drive mode (or stylus drive mode, or stylus uplink mode) At this time, the control unit 300 controls the sensor unit 10 to control a number of drive circuits 310 for driving the antennas. 0A'' may be electrically connected to a plurality of second patterns 102A''. 300 controls a number of switches to generate a number of conductive patterns connected to the second pattern 102A''. The functional patterns can be electrically connected to a number of driving circuits 310 .

[0351] The control unit 300 controls the driving circuits 310 connected to the second patterns 102A''. The control unit 300 can control the drive signal (or pen drive signal) output from the , among the plurality of driving circuit units 310 electrically connected to the plurality of second patterns 102A″, It is possible to control any two drive circuits so that they output pulse signals that are opposite to each other. Therefore, the control unit 300 can change and set the size and position of the current loop in various ways. It is possible.

[0352] In the stylus sensing mode (or the stylus downlink mode), the control unit 30 0 includes a plurality of sensing circuit units 330 for stylus sensing in the sensor unit 100A''. The second patterns 101A'' and the third patterns 103A are electrically connected to each other. This part is the stylus sensing mode of the touch input device shown in FIG. It is different from Do.

[0353] The control unit 300 controls a number of switches to generate a number of second patterns 101A'' and a number of The conductive pattern connected to the third pattern 103A is electrically connected to a plurality of sensing circuit units 330. can be linked to

[0354] The touch input device 500'' shown in FIG. 27 is different from the touch input device shown in FIG. In comparison, the multiple second patterns 102A'' of the sensor unit 100A'' are connected to the control unit 300. That is, the multiple second patterns 102A in FIG. Two adjacent second patterns are electrically connected by the first conductive pattern, and then the control 27. The control unit 300 is connected to the second conductive pattern 1. 02A″ are each connected to the control unit 300 by a conductive pattern. Due to its structural features, the touch input device 500'' shown in FIG. 27 is similar to the touch input device 500 of FIG. Although there is a drawback in that the number of channels is increased compared to the input device 500, the number of channels is increased to drive the stylus pen. In the antenna drive mode, the pen drive signal is generated only at the specific location where the stylus pen is positioned. Since a signal can be applied, there is an advantage that power consumption can be reduced.

[0355] Also, the touch input device 500 shown in FIG. 24 operates in a stylus sensing mode. The pattern that detects the signal emitted from the stylus pen is arranged in the longitudinal direction L as a number of first patterns. 27. The pattern 101A is a pattern of a plurality of third patterns 103A in the minor axis direction S. The illustrated touch input device 500'' is in stylus sensing mode and is configured to receive a stylus pen. A pattern for detecting a signal emitted from the second pattern 102A is arranged in the longitudinal direction L. '' and in the minor axis direction S there are a large number of third patterns 103A.

[0356] In the touch input device 500'' shown in FIG. 27, in the stylus sensing mode, The pattern in the longitudinal direction L that detects the signal emitted from the stylus pen is formed into a number of first patterns. If the number of second patterns 102A'' is not the turn 101A, the tap shown in FIG. Compared to the input device 500, the difference between the first pattern 101A and the second pattern 102A'' is This reduces the coupling capacitance of the touch sensor, making it ideal for sensing the touch position. To improve the operating frequency bandwidth of the touch drive signals and touch sense signals, This makes it possible to improve the operating frequency bandwidth of the pen drive signal for driving the stylus pen. This can be done.

[0357] In addition, in stylus sensing mode, the pen sensing signal from the stylus pen is sent to multiple The control unit 300 receives the pen sensing signal through the second pattern 102A''. In particular, in the longitudinal direction L, the voltage value of the control unit 300 is The voltage value of the pen sensing signal received at a distant point is relatively larger than that in FIG. This has the advantage of improving the sensing sensitivity. Considering the capacitive coupling between turn 102A Specifically, in the case of FIG. 24, as described above in FIG. 26(e), The capacitive coupling between the first pattern 101A and the second pattern 102A Therefore, a current flows from the second pattern 102A to the first pattern 101A. There is attenuation of the pen sensing signal input to the control unit 300 via 101A. The touch input device 500'' of the 27th embodiment has the second pattern 102, which is not the first pattern 101A. A'' is directly input to the control unit 300 without capacitive coupling, There is no attenuation of the pen-sensing signal due to capacitive coupling.

[0358] In addition, since each of the multiple second patterns 102A'' is configured with one channel, When a plurality of second patterns 102A'' are used as driving electrodes (Stylus TX), The distance between channels is reduced by half compared to 24-channel touch input devices, improving the driving resolution. There is a point.

For position sensing, a plurality of driving circuit units 310 are connected to a plurality of the sensor units 100A'''. The control unit 300 can electrically connect a number of switches to one pattern 101A. The conductive patterns connected to the first patterns 101A are connected to a plurality of driving circuits. The power supply 310 may be electrically connected to the power supply 310 .

[0367] In addition, the control unit 300 has a plurality of sensing circuits 330 for sensing the touch position. The third patterns 103A of the sensor portion 100A''' can be electrically connected to the third patterns 103A. The control unit 300 controls a number of switches to connect a number of third patterns 103A. The conductive pattern may be electrically connected to multiple sensing circuit units 330 .

The control unit 300 processes the output voltage value to determine the touch position. can be detected.

Any one of the plurality of driving circuits 310 electrically connected to the plurality of fourth patterns 104A'. The two drive circuits can be controlled to output opposite pulse signals. Therefore, the control unit 300 can change and set the size and position of the current loop in various ways. This can be done.

[0371] In the stylus sensing mode (or the stylus downlink mode), the control unit 30 10A includes a plurality of sensing circuit units 330 for stylus sensing. The first patterns 101A and the fourth patterns 104A' are electrically connected to each other. This part is different from the stylus sensing mode of the touch input device in FIG. become.

[0372] The control unit 300 controls a number of switches to generate a number of first patterns 101A and a number of second patterns 101B. The conductive patterns connected to the pattern 104A' are electrically connected to a plurality of sensing circuit units 330. It can be linked.

[0373] The touch input device 500''' shown in FIG. 28 is similar to the touch input device shown in FIG. In comparison, the multiple second patterns 102A''' of the sensor unit 100A''' are electrically floating. The stylus pen is not used because it is being routed. The difference is that the timing shown in Fig. 28 is driven by the The touch input device 500''' has an increased number of channels compared to the touch input device 500 of FIG. Although there is a drawback, since a large number of second patterns 102A are not used, a large number of second patterns 1 There is no conductive pattern connected to one end of O2A. This has the advantage that the thickness can be significantly reduced relatively compared to FIG.

[0374] The touch input device shown in FIG. 28 has a larger overall channel area than the touch input device shown in FIG. Although the number of patterns increases slightly, the number of patterns can be increased by using a stylus pen through a large number of fourth patterns 104A'.

[0376] In addition, the number of TX trace channels is reduced to 1 / 4 or 1 / 2 of that of the touch input device shown in FIG. 3, which has the advantage of reducing the thickness of the bezel B.

[0377] FIG. 29 is a diagram showing a specific embodiment of the touch input device shown in FIG.

[0378] Referring to FIG. 29, the touch input device 500′ includes a sensor unit 100A″ and the sensor The sub-unit 100A'' may include a control unit 300 for controlling the sub-unit 100A''.

[0379] The sensor unit 100A'' has a number of first to fourth patterns 101A', 102A', 103A', 104A', 105A', 106A', 107A', 108A', 109A', 110A', 111A', 112A', 113A', 114A', 115A', 116A Here, the third and fourth patterns 103A and 104A include: Since the third and fourth patterns 103A and 104A shown in FIG. 24 are identical to each other, The corresponding explanation will be omitted.

[0380] Although a number of first and second patterns 101A', 102A' will be described below, The explanation for the parts that are the same as the first and second patterns 101A and 102A in FIG. 24 will be as follows: For convenience, it will be omitted.

[0381] The first pattern 101A' has a shape extending along a first direction. The first pattern 101A′ may be in the long axis direction L of the screen of the input device. The pattern 101a' and the pattern 1b' are included. The turns 101b' are arranged along the first direction and spaced apart from each other at predetermined intervals.

[0382] The second pattern 102A′ has a shape extending along the first direction, and is A' and is disposed adjacent to the first pattern 101A' at a predetermined distance. The pattern 102A' includes a 2a pattern 102a' and a 2b pattern 102b'. The second pattern 102a' and the second pattern 102b' are arranged along the first direction. The 2a pattern 102a' and the 2b pattern 102 are spaced apart from each other by a predetermined distance. The second pattern 102A' including b' may also be named DTX (Dummy TX).

[0383] In the multiple first patterns 101A', one end of the multiple first patterns 101a' is restricted. The other end is electrically connected to the control unit 300, and the other end is electrically open. One end of the first pattern 101b' is electrically connected to the control unit 300, and the other end is electrically connected to the control unit 300. Here, one end is relatively close to the control unit 300, and the other end is relatively far from the control unit 300.

[0384] Each of the first ends of the first patterns 101a' is connected to a control unit 300 and a conductive pattern. The plurality of 1a patterns 101a′ and the control unit 300 may be electrically connected to each other via a plurality of 1a patterns 101a′. The conductive pattern connecting the conductive layer 502 and the conductive layer 503 is arranged in the minor axis direction S inside the bezel B of the touch input device 500. They may be arranged along

[0385] Each of the first ends of the first patterns 101b' is connected to the control unit 300 and the conductive pattern. The plurality of first patterns 101b' and the control unit 300 may be electrically connected to each other through a plurality of first patterns 101b'. The conductive pattern connecting the conductive layer 502 and the conductive layer 503 is arranged in the minor axis direction S inside the bezel B of the touch input device 500. They may be arranged along

[0386] In the multiple second patterns 102A′, one end of the multiple second patterns 102a′ is After the two adjacent ends are electrically connected to each other by the first conductive pattern, The control unit 300 is electrically connected to the second conductive pattern 1. The other end of each of the second electrodes 2a' is electrically connected to the corresponding second electrode 2b' via a conductive pattern.

[0576] As shown in FIG. 58, the first touch electrodes 111-1 and 111-2 and the first touch electrode The current direction between 111-3 to 111-10 is induced in the opposite direction. The sensing signal AB7 received by the first touch electrode 111-2 is The electrode 111-3 has an opposite sign.

[0578] FIG. 59 is a graph showing the sensing signals received from the second touch electrodes 121-1 to 121-16. be.

[0579] As shown in FIG. 59, the second touch electrodes 121-1 and 121-2 and the second touch electrode The current direction between 121-3 to 121-16 is induced in the opposite direction, so the second driving / receiving unit The sensing signal AB8 received by the second touch electrode 121-2 is The electrode 121-3 has an opposite sign. Therefore, a large current will be induced between the second touch electrode 121-2 and the second touch electrode 121-3. The magnitude of the current induced in the other second touch electrodes 121-1, 121-4 to 121-1 is The magnitude of the current induced in 6 is even greater.

[0581] Meanwhile, the signal measurement method of the touch part shown in FIGS. 49 to 59 is similar to that shown in FIGS. 16 to 45. Specifically, the first embodiment shown in FIG. Any one of the fourth patterns 101, 102, 103, and 104 is shown in FIG. The first touch electrodes 111-1 to 111-10 or the second touch electrodes 121-1 to 121-10 shown in For example, the first pattern 101 and the second pattern 102 shown in FIG. One of the two patterns 102 corresponds to the first touch electrodes 111-1 to 111-1 shown in FIG. -10, and either the third pattern 103 or the fourth pattern 104 shown in FIG. 49. .

[0582] For example, the first pattern 101 shown in FIG. 16 may be the first touch electrode shown in FIG. 49. 16 corresponds to 111-1 to 111-10, and the third pattern 103 shown in FIG. 16. In the case where the second touch electrodes 121-1 to 121-16 are connected to the sensor unit 10 in FIG. The first pattern 101 of a number of 0s is a pen sensing pattern in the horizontal axis direction, and the third pattern The pattern 103 can be a pen sensing pattern in the vertical axis direction. The control unit for controlling the first patterns 101 receives stylus pen sensing signals from the first patterns 101. The control unit receives the most significant stylus pen sensing signal from the plurality of first patterns 101. Two pen sensing patterns are scanned to output two pen sensing signals having maximum and minimum values. The touch point may be determined as a touch point on the horizontal axis of the stylus pen. The sign of the stylus pen sensing signal received from the third pattern 103 is reversed. , two pen detection signals each having the largest signal magnitude are output. The touch point on the vertical axis of the stylus pen can be determined between the patterns.

[0584] Alternatively, the control unit may receive stylus pen sensing signals from a plurality of first patterns 101. The signal is differentiated and the position on the pen sensing pattern where the differential value is maximum is determined by the side of the stylus pen.

The pen sensing signal is differentiated from the signal received from the pen sensing panel, and the differential value is maximized. The position on the turn can be determined as the touch point on the vertical axis of the stylus pen.

[0585] Alternatively, the control unit may select two adjacent first patterns from among the plurality of first patterns 101. and receives a differential signal from the stylus pen based on the maximum or minimum value of the received differential signal. The touch point can be determined, for example, by detecting a maximum or minimum value from the received differential signal. The position on the pen sensing pattern having the above formula can be determined as the horizontal axis touch point. Here, the two adjacent first patterns are two first patterns adjacent to each other. Alternatively, the two adjacent first patterns may be two first patterns that are not adjacent to each other. In turn, at least one other first pattern is arranged between the two first patterns. It may be placed.

[0586] In addition, the control unit selects two adjacent third patterns from among the plurality of third patterns 103. and receives a differential signal from the stylus pen based on the maximum or minimum value of the received differential signal. The touch point can be determined, for example, by detecting a maximum or minimum value from the received differential signal. The position on the pen sensing pattern having the above-mentioned value can be determined as the vertical axis touch point. Here, the two adjacent third patterns may be two third patterns adjacent to each other. Alternatively, the two adjacent third patterns may be two third patterns that are not adjacent to each other. At least one other third pattern is disposed between the two third patterns as a line. It is okay to do so.

[0594] The stylus pens 10a and 10b are driven by a drive signal applied to the loop coil 264. The resonance causes a current Ir to flow through the coil of the inductor section 14.

[0595] FIG. 62 shows the arrangement of electrodes (or patterns) and traces of the touch unit according to another embodiment. 1 is a diagram showing an example of a configuration;

[0596] The touch electrodes 111 and 121 in the sensor part of the touch part are located at the edge of the touch area. are connected to pads 113a and 113b via traces 112, 122a and 122b in the region. The first touch electrodes 111-1, 111-2, 111-3, . . . are connected to the respective traces. The second touch electrodes 121-1, 121-2, and 121-3 are connected to the base 112. -3, . . . are connected to the respective traces 122a, 122b.

[0597] The touch electrodes 111 and 121 and the traces 112, 122a, and 122b are formed on the same layer. The touch electrodes 111 and 121 and the traces 112, 122a, and 122b may be metal. Conductive materials with high transmittance and low impedance, such as silver nanowires and silver nanowires However, the touch electrodes 111 and 121 and the traces 112, 122a, and 122b may be formed by 22b may be located in a different layer and may be made of ITO, graphene, etc. It will not be done.

[0598] The pads 113a and 113b are connected to the touch controller 262. A signal (for example, a drive signal) from the controller 262 is transmitted to the touch electrodes 111 and 121. Signals (e.g., sensing signals) from the touch electrodes 111 and 121 are sent to the touch controller 262. To communicate.

[0599] FIG. 63 shows a touch input device 2 or a stylus driving device according to the present invention. FIG. 64 is a schematic diagram for explaining a method of driving a spin, and FIG. 64 is a schematic diagram for explaining a method of driving a spin, and Specific explanation of how to activate the stylus pen in the device 2 or stylus drive device This is a drawing that explains.

[0600] As shown in FIG. 63, the touch input device 2 according to the present invention uses a touch panel 261. The magnetic field is generated by the stylus 2, which operates the resonant circuit 12 of the stylus 2. The resonant circuit 12 includes a capacitor and an inductor, and is generated by the touch panel 261. An electric current is generated in the resonant circuit 12 of the stylus 2 by electromagnetic induction due to the electromagnetic field.

[0601] In Figure 64(a), the direction of the current flowing through the first electrodes extending along the Y axis is controlled to generate a magnetic field. (b) shows a method for generating a sine wave by controlling the direction of the current flowing through multiple second electrodes extending along the X axis. This shows a method for generating an electromagnetic field.

[0602] In another embodiment, the direction of the current flowing through the first electrode and the second electrode is simultaneously controlled to generate a magnetic field. As shown in the coordinate system in Figure 64, the horizontal direction of the drawing indicates the Y axis. The vertical direction of the drawing indicates the X-axis.

[0603] The direction of the current flowing through the plurality of first electrodes may be individually controlled. The direction of the current flowing through the electrodes arranged on the left and right sides of the chip position P is controlled in opposite directions. The touch is controlled based on the position of the first electrode centered on the tip of the stylus 2. The direction of current flowing through each of the plurality of first electrodes of the panel 261 is controlled. Since the plurality of first electrodes arranged in parallel do not form a closed loop, each of the plurality of first electrodes Individual current control must be performed for each.

[0604] As in the embodiment of the present invention, an electromagnetic field can be generated without forming a closed loop. For example, since it uses the conventional touch sensor as it is, it can be foldable or Various types of electronic devices such as rollables (smartphones, TVs, etc.) It can be applied immediately to existing production facilities and methods to achieve the same functions. This allows for economical manufacturing and, from another perspective, Even for existing products that only detect touch by touch, we will be able to do this through firmware upgrades, etc. This allows the use of a stylus, which has the effect of expanding the functionality of existing products. This becomes the case.

[0605] Referring again to FIG. 64(b), a virtual line parallel to the Y axis passing through the tip of stylus 2 is Based on the line, the current flowing through the first electrode located on the left side and the first electrode located on the right side is The flow directions are driven to be opposite to each other. It is also possible to control the current direction of the electrodes on both sides by determining the direction in advance. The entire surface of the device is divided into multiple regions, and the current direction of the electrodes included in each of the multiple regions is controlled. This allows the stylus 2 to react to the electromagnetic field wherever it is positioned on the touch panel 261. The electrodes arranged on the left edge of the divided area and the electrodes arranged on the right edge of the divided area can be One example is a method of controlling the direction of current in the electrodes in the opposite direction. There is no limitation, and various application examples and modifications can be considered.

[0606] As shown in Figure 64(b), the direction of the current flowing through the second electrodes is also individually controlled. At this time, the electrodes arranged above and below the position P of the tip of the stylus 2 are In other words, the tip of the stylus 2 is Based on the position of the centered second electrode, the direction of current flow through the second electrode is adjusted.

[0607] Since the plurality of second electrodes arranged adjacent to each other and parallel to each other do not form a closed loop, Individual current control must be provided for each second electrode.

[0608] More specifically, the upper side is measured using an imaginary line that passes through the tip of stylus 2 and is parallel to the X axis as a reference. The currents flowing through the second electrode placed on the top surface and the second electrode placed on the bottom surface are in opposite directions. At this time, in relation to the control of the current direction of each electrode, the touch panel 261 The current direction is controlled for all the included first electrodes and / or all the included second electrodes. However, if the position of the tip of the stylus 2 is known in advance, the stylus tip It is also possible to control only the electrodes within a certain distance from the loop.

[0609] Here, too, the entire surface of the touchpad 261 is divided into a plurality of regions, and each of the regions is By controlling the current direction of the electrodes included in each, the stylus 2 can be used to It is possible to make it possible to react to a magnetic field no matter where it is located on the divided area. A method for controlling the current direction of the electrode arranged on the upper edge and the electrode arranged on the lower edge in opposite directions. An example would be the formula.

[0610] Current flows in opposite directions from left to right and / or up to down around the tip of the stylus 2, creating an electromagnetic field. This induces a current in the resonant circuit 12 of the stylus 2, The stylus 2 generates an electromagnetic field signal. creates an electromagnetic field around the inductor coil, which A current signal is generated around the tip of the stylus 2. It has the characteristic of rotating clockwise or counterclockwise.

[0611] The touch input device 2 according to the embodiment of the present invention includes at least one touch panel 261. The electrode (or pattern) is used to receive the current signal generated from the stylus 2. By doing so, it is possible to determine the coordinates where the tip of the stylus 2 is located. The touch panel 261 receives signals generated by the activated stylus 2 and The method for determining the coordinates will now be described in detail.

[0612] Signal detection from a stylus pen The touch input device according to the embodiment of the present invention uses a touch panel 261 as a stylus. Detects the signal from the

In the following, the magnetic field signal of the stylus 2 is received. This section explains how to acquire touch coordinates.

[0615] Figure 66 shows the current signal generated by the magnetic field generated by the stylus 2. The electromagnetic field generated by the current induced in the resonant circuit 12 of the stylus 2 is As shown in Figure 66, a current signal is generated that rotates counterclockwise around the center. In an embodiment, a current signal may be generated that rotates in a clockwise direction. The rotating current signal may be, but is not limited to, an eddy current.

[0616] The current signal rotating counterclockwise is applied to the first electrodes 121Y-1 to 121Y-1 of the touch panel 261. This causes the current flow shown in Figure 66(a) for 1Y-m. The current signal that rotates counterclockwise with respect to the position P of the tip of the stylus 2 is The first electrode located on the left side of the chip of the second lath is drawn based on an imaginary line parallel to the Y axis. The first electrode and the second electrode are placed on the right side, and current flows in opposite directions. The current signal that rotates in the opposite direction is applied to the first electrode of the touch panel 261. would generate

[0617] Similarly, the current signal rotating counterclockwise is applied to the second electrodes 121X- This causes a current flow as shown in Figure 66(b) for 1 to 121X-n. That is, the current signal rotating counterclockwise with the tip position P of the stylus 2 as the reference is , based on an imaginary line passing through the tip of stylus 2 and parallel to the X axis, Create current flows in opposite directions between the second electrode and the second electrode located on the underside. The clockwise rotating current signal is applied to the second electrode of the touch panel 261 in the opposite direction. will generate a current signal of

[0618] In part A of Figure 66(b), the current signal generated by the stylus rotating counterclockwise is As explained above, a predetermined current is made to flow through the second electrodes. The traces connected to the poles are also rotated counterclockwise to produce a predetermined current. Since a current is formed, the current flow of the part of the second electrode included in the part A and the part of the second The current flows in the wires connected to the electrodes in opposite directions, and the current output from the wires On the other hand, in part B of Figure 66(b), The current flow of the other part of the second electrodes and the current flow of the wiring connected to the other part of the second electrodes are The current flows in the same direction, and the current output from the wiring connected to the other part of the second electrodes The magnitude of the current is relatively larger than the magnitude of the current output from the wiring included in part A. This is because the wiring is connected to one side of some of the second electrodes, and the wiring is connected to one side of the other second electrodes. This is because the other pole is connected to a wire.

[0619] FIG. 67 shows the current detected from the first electrode extending in the Y-axis direction when a signal is received from the stylus. 1 is a diagram illustrating a current signal (here, a tip signal) generated by a stylus 2. The direction of the current flowing through the first electrode is the same as that of the tip of the stylus 2. This will change depending on the position relative to the pool.

[0620] Specifically, the current signal generated by the stylus 2 is as shown in FIG. 67(a). If a clockwise rotating current is generated, the tip of stylus 2 is positioned left and right at the center. The direction of the current flowing through the first electrode is the direction of movement of the current signal generated by the stylus 2. The imaginary line CL that passes through the tip of stylus 2 and is parallel to the Y axis changes according to the rotation direction. With respect to y, the current flowing through the first electrode arranged on the left side is The direction of the current flowing through the electrodes is opposite to that of the current flowing through the electrodes.

[0621] The signals received by each of the n first electrodes are expressed as follows, as shown in the bottom graph of Figure 67(b): A sudden change in current occurs at the tip position of stylus 2, and after differentiating this, the peak value is calculated. By finding the corresponding coordinates, you can check the X coordinate value of the touch position by Stylus 2. Here, a differential signal is received from two adjacent first electrodes among the n first electrodes. The touch point of the stylus pen is determined based on the maximum or minimum value of the received differential signal. For example, the coordinates corresponding to the maximum or minimum value of the received differential signal can be calculated by The X coordinate value of the touch position by the ink pen 2 can be confirmed. The two first electrodes may be adjacent to each other. The two first electrodes are not adjacent to each other, and the two first electrodes At least one other first electrode may be disposed between the first electrodes.

[0622] Here, the direction of the current flowing through the first electrode of the touch panel 261 is the rotation (shift) of the current signal. For example, the current signal corresponds to the clockwise direction of the stylus tip. If the stylus rotates in the direction of the arrow, the first electrode located to the left of the tip of the stylus will The current flows in the upper direction, and the current flows in the lower direction for the electrode located on the right side. Conversely, the current signal rotates counterclockwise around the tip of the stylus. Then, the current flows downward to the electrode located to the left of the tip of the stylus. The direction of the current will correspond to the electrode located on the right side so that the current flows upward.

[0623] If we consider the current to move in a clockwise circular motion around the tip of the stylus, The electrode located to the left of the tip of the stylus has a 180° rotation from the circular motion locus. The current flows upward according to the tangent vector at the point, and the electrode located on the right It should be explained that the current flows downwards according to the tangent vector at the 0 degree point. can be done.

[0624] FIG. 68 shows the current detected from the second electrode extending in the X-axis direction when a signal is received from the stylus. 1 is a diagram illustrating a signal. A current signal generated by the stylus 2 causes a first electrode The direction of the current flowing through the sensor changes depending on the positional relationship with the tip of the stylus 2.

[0625] That is, the current flowing through the second electrodes arranged above and below the tip of the stylus 2 is having a direction corresponding to the direction of rotation of the current signal induced by the electromagnetic field of the stylus; Specifically, based on a virtual line CLx that passes through the tip of the stylus 2 and is parallel to the X axis, The current flowing through the second electrode arranged on the upper surface and the second electrode arranged on the lower surface is The direction of the current signal is opposite to the direction of rotation of the current signal.

[0626] By analyzing the signals detected from each of the m second electrodes, the position of the tip of the stylus 2 can be determined. A sudden change in current occurs at the position. After differentiating the detected current value, the coordinate corresponding to the peak value is calculated. is found and determined as the Y coordinate value of the touch position by the stylus 2. A differential signal is received from two adjacent second electrodes of the poles, and the maximum value of the received differential signal is obtained. Alternatively, the touch position of the stylus pen 2 can be determined based on the minimum value. The coordinates corresponding to the maximum or minimum value of the differential signal are calculated as the touch position by the stylus pen 2. Here, the Y coordinate value of the position of the adjacent second electrodes can be confirmed. Alternatively, the two adjacent second electrodes may be As two second electrodes that are not adjacent to each other, at least one other electrode is provided between the two second electrodes. The second electrode may be arranged.

[0627] The direction of the current flowing through each of the plurality of second electrodes of the touch panel 261 is determined by the stylus 2. The fact that it corresponds to the direction of rotation (movement) of the current signal caused by the If the signal rotates clockwise around the tip of the stylus, then the second electrode The current flows to the right side of the electrode located above the chip, and to the left side of the electrode located below. This means that the direction of the current corresponds to the direction of the current flowing through the If this were the case, the direction of the current flowing through each electrode would also be reversed.

[0628] If we assume that the current moves in a clockwise circular motion around the tip of the stylus, then the second current The electrode located above the tip of the stylus is at a point 90 degrees from the circular motion locus. The current flows to the right in response to the tangent vector at the electrode located below. This can be explained as the current flowing to the left in response to the tangent vector at the 270 degree point. This can be done.

[0629] In the embodiment of the present invention, the electrodes (or patterns) of the touch panel do not form a closed loop. can be used to activate the stylus 2 and detect the electromagnetic field signal of the stylus. That is, n first electrodes aligned in parallel, m second electrodes aligned in parallel perpendicular to each other, Each sensor receives the electromagnetic field signal of the stylus individually, so it can detect the touch position of the stylus. This allows for more precise detection.
