Description

[Technical field]

[0001] The present disclosure relates to pen and touch input systems and controllers, A touch input device includes a sensor unit and can operate with a stylus pen. The present invention relates to a pen and touch input system and a controller for controlling a sensor unit. [Background technology]

[0002] Mobile phones, smart phones, laptop computers, digital Digital broadcasting terminals, PDAs (personal digital assistants), PMPs (portable multimedia ia player), navigation, slate PC, tablet PC ), Ultrabooks, and wearable devices. A variety of 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. The touch sensor can be located on the touch screen or as part of the touch input device. By interacting with electronic devices by touching the screen, touch input devices provide an intuitive user experience. A user interface can be provided to the user.

[0004] Users can use a stylus pen for precise touch input. The Raspberry Pi is active 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, it requires a power source and a battery charging system, so it is difficult to use except for some advanced users. The disadvantage is that there are not many users.

[0006] Passive stylus pens are cheaper than active stylus pens and do not require batteries. It has the advantage of not requiring a touch sensor, but it requires more precise touch recognition than an active stylus pen. However, recently, passive sensors that can recognize touches precisely have been developed. To realize the ink pen, we used EMR (Electromagnetic Resonator) which is an inductive resonance method. The technologies proposed are ctrO Magnetic Resonance and capacitive resonance. It has been done.

[0007] The EMR method has the advantage of the quality of writing / drawing, 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. However, this has the disadvantage of being thick and therefore more expensive.

[0008] The capacitive resonance method is similar to the general capacitance touch sensor and touch controller. By using a laser IC, there is no additional cost, and the performance of the IC is improved to support pen touch. This is a 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 controlled by the resonator built into the stylus pen. The resonant frequency of the circuit is almost the same as that of the conventional EMR method or the capacitance method. In the active resonance method, even if the resonance frequency and the drive signal frequency match, there is no attenuation of the signal transmission. The problem is that the signal transmission is difficult due to the large size of the touch panel. Despite years of attempts by controller IC vendors, the output signal is still not sufficient for mass production. The reality is that there are no successful manufacturers.

[0010] Therefore, the EMR method or the capacitive resonant switch that can produce the maximum output signal is used. 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 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 has a closely packed array of coils in which a current can be induced by a magnetic signal to receive Such a digitizer can accommodate the miniaturization and thinning of touch input devices. There is also the problem that it is not possible to design flexibly. Summary of the Invention [Problem to be solved by the invention]

[0175] FIG. 1a shows a pen and touch input system including a stylus pen and a touch input device. This is a conceptual diagram.

[0176] Referring to FIG. 1a, a stylus pen 10 is connected to a touch screen 2 of a touch input device 2. 0, a signal output from the touch input device 2 or the touch screen 20 is received (or , uplink) and transmits a signal to the touch screen 20 (or downlink) Here, the touch input device 2 includes a sensor unit and a The control unit controls the stylus pen 10 and interacts with the stylus pen 10. It may also be called a "power device."

[0177] FIG. 1b shows an uplink in the pen and touch input system shown in FIG. nk) and downlink.

[0178] Referring to the left diagram of FIG. 1b, the uplink is performed inside the stylus pen 10 of FIG. An electromotive force (V2, or Vemf) is generated in the coil. 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 to each other like a transformer. It works with a transformer.

[0179] FIG. 1c illustrates the spacing between the + and - drive channels in the uplink. This is a drawing for clarification.

[0180] 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 + and - drive channels is It is preferable to widen the gap (4 mm) by at least one channel.

[0181] FIG. 1d illustrates another embodiment of a pen and touch input system including a stylus pen and a touch input device. FIG. 1 is a conceptual diagram showing an embodiment.

[0182] Referring to FIG. 1d, the touch input device 2 is foldable. The pen 10 touches the touch screen 20 of the foldable touch input device 2 in the vicinity of the touch screen 20. Receives a signal output from the input device 2 or the touch screen 20, and You can send a signal to 0.

[0183] A rectangular foldable touch input device 2 or a touch screen 20 included therein In the component, 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 short side located on the upper side is the first short side SS1, and the short side located on the lower side is the second short side S We will refer to it as S2.

[0184] The foldable touch input device 2 has a fold that crosses the first short side SS1 and the second short side SS2. The folding axis AXIS_F is used as a reference to bend along a specified folding direction. That is, the foldable touch input device 2 can be moved based on the folding axis AXIS_F. As a criterion, the folded and unfolded states are It may be possible for the state to be transitioned between the folded state and the unfolded state.

[0185] FIG. 2a is a schematic diagram showing a signal transmission operation between a stylus pen and a touch input device. It is a surface.

[0186] Referring to FIG. 2a (a), the touch screen 20a includes a digitizer 29, a display The display device includes a ray panel 251 , a sensor unit 21 , and a window 22 .

[0187] 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. .

[0188] The digitizer 29 may be attached below the display panel 251 and may include 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 magnetic fields when the antenna loop forms a magnetic field. Ferrite sheet that blocks eddy currents that may be generated in electrical elements and components ).

[0189] 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. The FPCB has a shape overlapping in the Z-axis direction. This makes the FPCB thick. When the digitizer 29 is used, it is difficult to make the touch input device 2 thin and compact.

[0190] 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 can occur when the wiring material is folded repeatedly to form an antenna loop. Stress is applied and can eventually lead to damage to the wiring material. Ferrite sheets are The effect of the magnetic field generated by the antenna loop on the inside of the touch input device 2 is blocked. 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.

[0191] Referring to FIG. 2a (b), the touch screen 20b includes a display panel 251 , a sensor portion 21 , and a window 22 .

[0192] 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 are styled. It is possible to receive an input of a resonated electromagnetic signal (E and / or B) from the pen 10. The electrodes (or patterns) of the sensor unit 21 are made of a metal mesh with low resistance. When formed, a magnetic signal from the stylus pen 10 can be detected.

[0193] Similarly, in comparison to digitizer 29, touch screen 20b converts magnetic signals into a stylus signal. No additional units or modules are required to transmit to the Spin 10, so touch The screen 20b can be made thinner, which is advantageous in terms of manufacturing costs.

[0194] Referring to FIG. 2a (c), the touch screen 20c includes a loop coil 264, a disk drive, and a It includes a spray panel 251 , a sensor portion 21 , and a window 22 .

[0195] 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 exposed to the stylus pen 10. It can receive as input an oscillating electromagnetic signal (E and / or B).

[0196] Compared to the digitizer 29, the loop coil 264 has a magnetic field for detecting the touch position. Since it does not receive the 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 a foldable / flexible touch input device 2.

[0197] 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, silver, etc. In addition to the substrate, it may be located on the same layer as the sensor unit 21. In this case, the antenna loop High transmittance such as metal mesh, ITO, graphene, silver nanowire, etc. The antenna loop may be formed of a conductive material exhibiting 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.

[0198] 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 first touch electrode and a second touch electrode 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 in 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.

[0251] FIG. 5 is a diagram showing a specific example of the inductor portion of the stylus pen shown in FIG. 4(a) and (b). FIG.

[0252] Referring to FIG. 5, the inductor section 14 includes a ferrite core 115 and a ferrite core 1 15 includes a coil 116 wound around it.

[0253] At this time, the inductance of the inductor unit 14 is calculated by the following Equation 1: is determined. <Formula 1> As can be seen from TIFF2025028986000002.tif12137<Formula 1>, the inductance (L) is determined by the magnetic permeability of the ferrite core 115. The permeability of the coil 116 is proportional to the cross-sectional area of ​​the coil 116 and the number of turns. It is inversely proportional to the length of the winding.

[0254] 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, 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 given by Q=2dfL / R. Here, L and R are the inductance and resistance of the coil, respectively, and f is the frequency. The higher the Q value of the coil, the sharper the resonance characteristics can be obtained.

[0255] In the design of the stylus pen shown in FIG. 4(a) and (b), L is the length of the stylus to be used. The self-resonance frequency must be large enough for 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. A method is needed that can do this.

[0256] In the following embodiments, various ferrite core materials, coil wire types, and winding methods are used. We will explain the most optimized stylus pen design method among (winding scheme) .

[0257] (1) Ferrite core material The material of the ferrite core used in this embodiment is manganese (Mn), nickel (Ni). was used.

[0258] (2) Wire type The types of coil wire used in this embodiment are enameled wire and Litz wire. .

[0259] As shown in FIG. 7, the enameled wire 100 is made of an insulating enamel 102 on the surface of a copper wire 101. This 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.

[0260] As shown in FIG. 8, the Litz wire 200 is a thin insulated wire having a diameter of about 0.1 mm. A wire 100 (for example, an enameled wire) is twisted together into one, and then nylon or other material is applied to the wire. The Litz wire 200 is a special insulated wire with an insulating coating 201. This reduces the skin effect, and it is used in coils in high-frequency circuits.

[0261] In this embodiment, the total thickness (T) is 0.2 mm, the wire diameter (Φ) is 0.06 mm, A Litz wire with a sheath thickness (t) of 0.007 mm was used.

[0262] (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 turns), a winding method having a multi-layer winding structure is used. Specifically, as shown in (A) and (B) of FIG. 9, two types of multi-layer A winding method was used.

[0263] The winding method in Figure 9(A) is the simplest winding method. Once the lower layer winding is completed, the layer immediately above it is wound. This is a sequential layer winding scheme. In the (A) type of 9, the winding of the layer immediately above begins where the winding of the previous layer ends. In the following, this will be referred to as the U-type winding method.

[0264] The winding method shown in FIG. 9B is a method in which adjacent winding layers are wound alternately. r winding scheme, in which adjacent layers of windings are wound in a zigzag pattern In the following, this is called the zigzag type winding method. After winding the second layer on the wire, the third layer is wound between the first and second layers. The fourth layer is wound on top of the second layer, and the fifth layer is wound on top of the second layer. This zigzag type winding method is a method of winding between adjacent windings of the fourth layer. 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.

[0265] Comparative experiment 1 (Comparison of characteristic values ​​by material) The coil wire type is enameled wire, and the coil is wound using the U-type winding method. The Q value was measured by changing the material of the tocore to manganese, nickel, and magnesium.

[0266] As a result of the measurement, there was almost no difference in the Q value of each core material, and the measured Q value was also The level was far below what we could have hoped for.

[0267] Comparative experiment 2 (Comparison of characteristic values ​​by winding type) The ferrite core is wound with manganese (Mn) and U-type winding method. Inductor 1 and Inductor 2 are made with enameled wire and Litz wire, respectively. The Q value of Kuta 2 was measured.

[0268] Figure 8 shows the frequency change via the KEYSIGHT TECHNOGIES E4980A precision LCR meter. 13 is a graph showing the Q values ​​of inductor 1 and inductor 2 measured by the same method.

[0269] In Fig. 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 a waveform showing the change in Q value with respect to frequency This is a waveform showing the change in Q value versus frequency for a Litz wire / U-type winding method.

[0270] Inductor 2 made of Litz wire has a Q of 0.01 at a frequency of about 400 kHz (frequency f1). The value is almost the maximum value, and inductor 1 made of enameled wire, the frequency is around 150 kHz. At wave number (frequency f2), the Q value is almost at its maximum value.

[0271] 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.

[0272] However, the maximum Q value of inductor 2 measured in comparison experiment 2 was also below the target value required for commercialization (Qt This was only about half the level of the target.

[0273] Comparative experiment 3 (Comparison of characteristic values ​​by winding method) The ferrite core material was changed to manganese (Mn), and the wire type was changed to enameled wire and reinforcing wire. Inductors 3 and 4 were manufactured using U-type and zigzag-type winding methods. The Q value of inductor 5 was measured.

[0274] Figure 11 shows the results of changing the frequency through the E4980A precision LCR meter from KEYSIGHT TECHNOGIES. 13 is a graph showing further measured Q values ​​of inductors 3 to 5.

[0275] In Figure 11, a is inductor 3 (manganese core / enamel wire / U-type winding method) ) is a waveform showing the change in the Q value with respect to frequency, and b is a waveform showing the change in the Q value with respect to frequency This is a waveform showing the change in Q value against frequency (enameled wire / zigzag type winding method), c is the frequency of inductor 5 (manganese core / litz wire / zigzag type winding method) 4 is a waveform showing the change in the Q value.

[0276] As can be seen from the waveform in Figure 11c, 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 about 300 kHz (frequency f3). Inductor 4 made with wire / zigzag winding method and inductor 5 made with enameled wire / U-type winding method Inductor 3 showed a maximum Q value at a frequency of about 150 kHz (frequency f2). vinegar.

[0277] 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.

[0278] However, the inductor 5 (manganese core / litz wire / zigzag tube) measured in the comparative experiment 2 The target value (Qtarget) required for commercialization of the 1000V coil winding method was only about 3 / 4 of the target value (Qtarget) required for commercialization of the 1000V coil winding method. .

[0279] 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 manganese is known to be 300-5000, while that of galvanne is 200-300. is.

[0280] 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 each are the same, the number of The advantage of this is that the number of windings in a nickel-nickel alloy can be reduced by about four times. Therefore, from the viewpoint of the number of windings alone, it is more effective to use manganese than nickel. It becomes clear that...

[0281] 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 reduce Q As the value decreases, there is the problem of reducing the amplitude of the resonant signal.

[0282] The parasitic capacitance formed in the inductor section 14 is between the wound coil and the core. However, as mentioned above, the zigzag type winding method is used to prevent this. This reduces the parasitic capacitance between the wound coils.

[0283] 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 optimal material for light cores.

[0284] 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 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 not even available on the data sheets provided by the manufacturers.

[0285] In this embodiment, in order to confirm the dielectric constant of manganese and nickel, KEYSIGHT TECHNOGIE Using S's E4980A precision LCR meter, the permittivity of manganese and nickel was measured. The results are shown in Table 1 below. [Table 1] Measurement 1 and Measurement 2 were performed using the same KEYSIGHT TECHNOGIES E4980A precision LCR meter. Measurement 1 was performed using the dielectric constant calculated automatically by the measurement software. According to measurement 1, the dielectric constant of manganese is 2400, while the dielectric constant of nickel is It is clear that this will not be the case.

[0286] Measurement 2 measures the capacitance, area, and distance between the ferrite cores to calculate the dielectric constant According to the method described above, the dielectric constant of manganese is 8300, and that of nickel is 8300. The dielectric constant was measured to be 2.

[0287] There is a large difference in the dielectric constant between measurements 1 and 2, especially in the case of measurement 2. It was confirmed that there was a considerable error due to the persistence, area, distance, etc. However, measurement 1 and The results of measurement 2 showed that nickel has a dielectric constant at least 1 / 1000 smaller than that of manganese. It becomes clear that...

[0288] 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.

[0289] Figure 12 shows the results of changing the frequency through the E4980A precision LCR meter from KEYSIGHT TECHNOGIES. 13 is a diagram showing further measured Q values ​​of inductor 6 and inductor 7.

[0290] In FIG. 12, a is inductor 6 (nickel core / litz wire / U-type winding method) a is a waveform showing the change in the Q value with respect to the frequency of the inductor 7 (nickel core / ribbon) 4 is a waveform showing the change in Q value versus frequency for a 100-V AC / 100-V DC inductor (zigzag type winding method).

[0291] As can be seen from the waveform in Figure 12b, it is manufactured using a nickel core / Litz wire / zigzag winding method. In the case of inductor 7, the Q value reaches almost the maximum value at a frequency of about 400 kHz (frequency f5). Inductor 6, which is made with nickel core / Litz wire / U-type winding method, has a resistance of 200 The Q value reaches its maximum value at a frequency of around 100 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.

[0292] On the other hand, inductor 7 (nickel core / litz wire / zigzag tie) measured in comparison 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.

[0293] In the above-described Comparative Experiments 1 to 4, the material of the ferrite core, the type of coil wire, etc. By changing the combination of the type and winding scheme, the inductor was manufactured and the Q value was The results showed that the winding method of nickel core, Litz wire, and zigzag type was used. Obtaining the highest Q value 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.

[0294] On the other hand, in this embodiment, a nickel core is used as the ferrite core, and the wire of the core The experiment used Litz wire as the core, but in addition to the nickel core, ferrite core was also used. Uses a material with a dielectric constant of 1000 or less, and has two or more insulated wires in one coil other than Litz wire. Similar results can be obtained when using wires wrapped around strands. I guess so.

[0295] In the following, a touch input device in a pen and touch input system according to an embodiment of the present invention will be described. Before we go into the details of where to place the stylus, let us first consider how the position of the stylus on the touch screen affects the display. Explain why the output voltage (Vout) of the CVA (Capacitor Voltage Amplitude) changes .

[0296] FIG. 13 shows the CVA (Ca) depending on the position of the stylus pen 10 on a conventional touch screen. A schematic diagram to explain the change in the output voltage (Vout) of the This is a drawing.

[0297] Referring to FIG. 13, the CVA is determined according to 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 problem is that the impedance ratio of

[0298] Based on the long axis of a conventional touch screen, the Metal Mesh touch sensor The resistor (R) is approximately 1.2k (ohms) and the capacitor (C) is approximately 250pF.

[0299] Based on 10 distributed models, the driving frequency is 300kHz. The impedance of the capacitor is about 200 times higher than that of the resistor (120 ohms vs. .1 / (2π*300k*25pF)=21k(ohm) is larger. Therefore, the capacitor is the main This is the cause.

[0300] FIG. 14 shows the output voltages (Vout1, Vo ut2) is different through current sensing. FIG. 15 shows the output voltage of the CVA according to the position of the stylus pen 10 in FIG. (Vout1, Vout2) are different through voltage sensing. 1 is a diagram for explaining the invention;

[0301] 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.

[0302] 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.

[0303] FIG. 16 is a schematic diagram of a sensor unit 100 of a touch input device according to a first embodiment of the present invention. This is a schematic diagram.

[0304] 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 touch input device having a wide and high The control unit (not shown) that controls the sensor unit 100 is disposed below the sensor unit 100. For example, such a touch input device may be configured to correspond to the shape of a smartphone. .

[0305] 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 a signal (stylus pen signal) emitted from the stylus pen and displays it on the screen The position of the placed stylus pen can be detected.

[0306] The sensor unit 100 includes a number of patterns (or a number of electrodes).

[0307] The sensor unit 100 has a number of first to fourth patterns 101, 102, 103, and 104. It may include.

[0308] The first pattern 101 has a shape extending along an arbitrary first direction y. The first direction is The first pattern 101 may be in the long axis direction 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 tract may have a predetermined shape formed therein.

[0309] The second pattern 102 has a shape extending along the first direction y, and is aligned with the first pattern 101. The second pattern 101 is disposed adjacent to the first pattern 101 and is spaced a predetermined distance from the first pattern 101. The second pattern 102 may be named DTX (Dummy TX). 101 and may have a predetermined shape in which an electrical path is formed along the first direction y.

[0310] The third pattern 103 has a shape extending along a second direction x different from the first direction. The second direction x may be perpendicular to the first direction y and may be in the minor axis direction of the screen of the touch input device. The third pattern 103 may 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.

[0311] The fourth pattern 104 has a shape extending along the second direction x and is aligned with the third pattern 103. The fourth pattern 102 is disposed adjacent to the third pattern 103 and is disposed at a predetermined distance from the third pattern 103. The fourth pattern 104 may be named DRX (dummy RX). 03 and may have a predetermined shape in which an electrical path is formed along the second direction x.

[0312] 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.

[0313] The plurality of first patterns 101 are arranged along a second direction x, and the plurality of second patterns 102 are arranged along a second direction x. The third patterns 103 are also arranged in the second direction x. A large number of fourth patterns 104 are also arranged along the first direction y.

[0314] The first pattern 101 extends along a first direction y and the third pattern 103 extends along a second direction x. Since the first direction y is longer than the second direction x, the number of the 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 a majority of the third patterns 103 .

[0315] Here, the number of the multiple first patterns 101 and the number of the multiple third patterns 103 are It may be increased or decreased depending on the size of the screen of the input device.

[0316] The multiple second patterns 102 correspond one-to-one to the multiple first patterns 101 and have the same individual The other end (or the second side end) of each of the multiple second patterns 102 may be , are electrically connected to each other through a conductive pattern. Here, the conductive pattern is The material may be Metal Mesh or Silver Trace.

[0317] 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 to each other. One end of each of the two or more second patterns 102 may be electrically connected to each other via a conductive pattern. With this configuration, the number of channels in the multiple second patterns 102 is the same as that in the multiple first patterns. The number of channels in the second pattern 102 may be reduced to half that of the first pattern 101. The two or more second patterns 102 may be adjacent to each other.

[0318] Meanwhile, as shown in FIG. 18, one end of each of the second patterns 102 is individually It may be connected to one conductive pattern.

[0319] Referring again to FIG. 16, a 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 the same as the number of channels in the first pattern 101. More than the number of channels.

[0320] The fourth patterns 104 correspond one-to-one to the third patterns 103 and have the same individual The other end (or the second side end) of each of the fourth patterns 104 may be , are electrically connected via the conductive pattern.

[0321] In the sensor unit 100 of the touch input device shown in FIG. The turn 101 and the multiple third patterns 103 are essentially the touch of a finger-like object. To this end, a touch driving signal is applied to the first patterns 101. The touch driving electrodes (TX electrodes) are connected to the touch sensing electrodes 102 and 103, and the touch sensing signals are received by the third patterns 103. It can operate with touch sensing electrodes (RX electrodes, or touch receiving electrodes) that receive a signal. Of course, it can also work the other way around.

[0322] The sensor unit 100 of the touch input device shown in FIG. 16 drives a stylus pen. In order to perform sensing by detecting the number of first to fourth patterns 101, 102, 2, 103, and 104 may be used in various combinations. In Table 2 below, "1" indicates a number of first patterns 101. , "2" is a number of second patterns 102, "3" is a number of third patterns 103, and "4" is a number of indicates a number of fourth patterns 104. [Table 2] Referring to Table 2 above, in various combinations (No. 1 to No. 32), many first The pattern 101 and a number of third patterns 103 are used to 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.

[0323] At least one of the first to fourth patterns 101, 102, 103, and 104 Or two of them act as stylus driving electrodes for driving a stylus pen. At least one of the first to fourth patterns 101, 102, 103, and 104 can be 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, the Y-axis drive is a number of third patterns 103 and a number of fourth patterns 10 4. The drive of the stylus pen may be either X-axis drive or Y-axis drive. Either one is possible, or both are possible.

[0324] At least one of the first to fourth patterns 101, 102, 103, and 104 Or the second is a sensor for sensing the stylus pen signal emitted from the stylus pen. For example, it can be used to sense the signal of a stylus pen. In order to achieve this, both X-axis sensing and Y-axis sensing are required, so many first to fourth patterns are required. Two of the patterns 101, 102, 103, and 104 can be used. X-axis The sensing is performed on 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 any one of them.

[0325] In the above Table 2, the "uplink signal strength" refers to the signal strength of the start It means the magnitude of the drive signal for driving the stylus pen 10. A driving signal is applied to a number of first patterns 101 and a number of second patterns 102, respectively. When comparing the strength of the signal received by the stylus pen, it is found that there are many second patterns 102. When a stylus pen driving signal is applied, the stylus pen is applied to a number of first patterns 101. The uplink signal is relatively larger than when the drive signal is applied.

[0326] 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 driving signal is applied, At least one current loop is formed, but the other end of the first pattern 101 is (or the second end) are not electrically connected to each other, so no current loop can be formed. When a current flows through each of the first patterns 101, the RC of each of the first patterns 101 becomes As a result of charging, one end (or a 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 ... The current is transmitted to a number of second patterns 102 in which current loops are formed via couplings. At this time, signal attenuation occurs due to capacitive coupling.

[0327] Similarly, when a stylus pen driving signal is applied to a number of fourth patterns 104, When the stylus pen driving signal is applied to the third pattern 103, the uplink signal is Contrastingly larger.

[0328] In the above Table 2, the "downlink signal magnitude" refers to the signal strength of the 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 102 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 larger than when received over the 1000 MHz band.

[0329] The reason is that the other ends (second side ends) of the second patterns 102 are electrically connected to each other. A current loop is formed at the other end (first side end) of the multiple first patterns 101. are not electrically connected to each other, and in particular, current flows through capacitive coupling. The stylus pen signal is fed from the second pattern 102 having the loops to the first pattern 103. This is because the downlink signal is transmitted to the node 101, causing attenuation of the downlink signal.

[0330] 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.

[0331] 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 tag. A large number of second pads are used for driving and sensing the stylus pen. If turns 102 and / or 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 number of first patterns 101 and / or third patterns 103 for touch sensing are provided. When used, no additional channel is required (shown as "none" in Table 2).

When the resistor 104 is electrically floating, That is, the other ends (second side ends) of the fourth patterns 104 are electrically connected to each other. The fourth patterns 104 are connected to one end (first side end) of the fourth patterns 104. It may mean that there is no

At least one of the first pattern 101 to the fourth pattern 104 The reason for selecting the electrode for driving the pen is that the touch screen 2 of the touch input device 2 shown in FIG. The position of the stylus pen 10 on the screen 20 may change depending on the position of the stylus pen 10. The pattern selected when in the hover state is the one selected when the stylus is in contact with the For example, the control unit (not shown) may select a different pattern from the pattern selected when the control unit is in a locked state. First, when the stylus pen is in a hover state, the first and second patterns 101, 1 When any one of 02 is selected as the pen drive electrode and the stylus pen is in contact In this case, either one of the third and fourth patterns 103 and 104 is selected as a pen driving electrode. Of course, the opposite is also possible.

The selection is made by using a stylus on the touch screen 20 of the touch input device 2 of FIG. This may change depending on the position of the stylus 10. When the stylus is in a hover state, The pattern selected when the stylus pen is in contact is For example, the control unit (not shown) may select a different pattern from the stylus pattern. When the button is in a hover state, either the first or second pattern 101 or 102 is displayed. When the stylus pen is in contact with the sensor, the third and fourth electrodes are selected as the sensing electrodes. Either one of the fourth patterns 103 and 104 can be selected as a pen sensing electrode. Yes, you can. Of course, the opposite is also possible.

[0358] FIG. 19 is a schematic diagram of a sensor unit 100' of a touch input device according to a second embodiment of the present invention. FIG.

[0359] The touch input device according to the second embodiment of the present invention is a landscape type. Such a landscape type touch input device has a high The sensor unit 100' is larger than the sensor unit 100', and a control unit (not shown) for controlling the sensor unit 100' is provided below the sensor unit 100'. For example, such a touch input device may be arranged in a shape that corresponds to the shape of a tablet PC. It is possible.

[0360] The structure 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 the same as that of the sensor unit 100 of the touch input device according to the first embodiment. This is the same as rotating it 90 degrees.

[0361] The sensor unit 100' of the touch input device according to the second embodiment of the present invention includes a plurality of first to fourth 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 plates 102 are arranged adjacent to each other and extend 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 disposed 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.

[0362] The sensor unit 100' of the touch input device according to the second embodiment shown in FIG. The screen size of a single-screen tablet PC is about 10 to 14 inches, and the In the case of the example of No. 1 in Table 2, the total channel (Total Cha The number of 1000 nnel and the number of TX Trace Channels are roughly , as shown in Table 3 below. [Table 3] In the above table 3, the number of channels of Stylus TX is a number of 101 pieces of the first pattern. This is a value obtained by dividing the number of the second patterns 102 by the number of the first patterns. 20, the number of the second patterns 101 is the same as that of the first patterns 102. One end (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.

[0363] In the above table 3, 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 thickness of the transverse 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 more Therefore, the thickness of the widthwise bezel of the touch input device can be reduced.

[0364] On the other hand, the screen size of the touch input device shown in FIG. 19 is smaller than that of a smartphone. For example, if the screen size 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 unit 100' are increased. The increase in the resistance and capacitance is caused by the first or third touch drive pattern. 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 operating frequency bandwidth required for the design cannot be obtained. In order 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 problems will occur. However, the problem cannot be solved.

[0365] In addition, the stylus pen is used to input the stylus information to the control unit of the touch input device. The pen signal is also attenuated as the sensor section 100' becomes larger. The first to fourth patterns 101, 102, 103, and 104 are the furthest 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.

[0366] The above problems are No. 3, 4, 7, 8, 11, 12, 15, 16, 1 in above. Many second patterns, such as 9, 20, 23, 24, 27, 28, 31, and 32, are used. 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 in the examples of 26, 28, 30, and 32, a number of fourth patterns 104 are generated as stylus pen signals. This problem can be solved by using the electrode as a stylus pen sensing electrode. In the example, a large number of second and fourth patterns 102 and 104 are magnetically induced by a stylus pen. In order to receive electromotive force directly through the fourth pattern 102, the second pattern 102 is connected to the first pattern 101. Signal attenuation via capacitive coupling from pattern 104 to third pattern 103 There is no decline.

[0367] 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 tablet PC is about 10 to 14 inches. In the case of the example of No. 3 in Table 2 above, the total channels of the sensor unit 100′ The number of trace channels (TX Trace Channels) and the number of driving trace channels (TX Trace Channels) are summarized as follows: This is shown in Table 4. [Table 4] In the above , the number of channels of Stylus TX is the same as the number of second patterns 102. This is because 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 , each of which is connected to a conductive pattern.

[0368] In the above table 4, 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 short axis of the touch input device. This is the main factor that determines the thickness of the bezel. The more this is reduced, the greater the reduction in bezel thickness on the minor axis of the touch input device.

[0369] The example in above has the disadvantage that the number of channels is slightly increased compared to above. 102, the number of first patterns 101 is not a number of second patterns 102, and the number of second patterns 102 is a number of patterns. 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 The applicant has a further advantage in 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 .

[0370] In addition, since each of the multiple second patterns 102 is composed of 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.

[0371] 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 about 10 to 14 inches. In the case of the example of No. 8 in Table 2, the total number of channels (T The number of external channels and the number of driving trace channels (TX Trace Channels) are , as shown in Table 5 below. [Table 5] In the above Table 5, the number of channels of Stylus TX is a number of 4th pattern 104 pieces. This means that the number of the fourth patterns 104 is equal to the number of the third patterns 10 22, the number of the fourth patterns 104 is equal to the number of the third patterns 104. Each of them is individually connected to a conductive pattern.

[0372] In the above table 5, 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 better the tapping. The thickness of the bezel on the short axis of the input device can be reduced.

[0373] The above has the disadvantage that the total number of channels is slightly increased compared to the above example. 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 controller becomes larger.

[0374] In addition, since each of the fourth patterns 104 is composed of one channel, When the fourth pattern 104 is used as a driving electrode (Stylus TX), This has the advantage of improving drive resolution since the spacing between channels is reduced by half compared to the previous example.

[0375] 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 that the thickness of the width direction bezel B of the touch input device can be reduced.

[0376] FIG. 23 is a schematic diagram showing yet another example of the sensor unit 100′ shown in FIG. FIG.

[0377] 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, 104 are the same as the sensor unit 100 in FIG.

[0378] The 1a pattern 101a and the 1b pattern 101b are arranged in an extension direction of the 1st pattern 101′. The second pattern 102a and the second pattern 102b are arranged along the second pattern. The electrodes 102' are arranged along the extension direction of the coil 102'.

[0379] 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.

[0380] At one end of the multiple 2a patterns 102a, two or more adjacent 2a patterns are One end of each of the second patterns 102b may be electrically connected to two or more adjacent second patterns 102b. A 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 individually electrically connected to the conductive pattern.

[0381] As a specific example, the sensor unit 100'' shown in FIG. 23 is a landscape type. The screen size of a tablet PC is about 10 to 14 inches, and the N When configured as in the example of o.1, the individual channels of the sensor unit 100'' are The number of trace channels and the number of TX Trace Channels are summarized in Table 6 below. be. [Table 6] In Table 6 above, the number of channels of the Stylus TX is a number of the second pattern 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 a value obtained by dividing the number of the first patterns 102′ by 2. 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.

[0382] In the above table 6, 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 main factor that determines the thickness of the bezel. The more this is reduced, the greater the reduction in bezel thickness on the minor axis of the touch input device.

[0383] The above has the disadvantage that the number of channels is slightly increased compared to the above example. Since the length of each of the first pattern 101' and the second pattern 102' is reduced by half, the sensor unit 1 The touch drive voltage is applied to the touch drive electrode by reducing the resistance and capacitance of 00''. The operating frequency bandwidth of the signal and the pen drive signal for driving the stylus pen can be increased. There is an advantage to being able to do this.

It is also possible to control the voltage to be applied.

[0423] Antenna drive mode (or stylus drive mode, or stylus uplink mode) At this time, the control unit 300 controls a number of driving circuits 310 for driving the antennas in the sensor unit 10. 0A to a plurality of second patterns 102A. , and controls a number of switches to connect a number of conductive patterns connected to the second pattern 102A. The driver circuit units 310 may be electrically connected to each other.

[0424] The control unit 300 outputs the driving circuits 310 connected to the second patterns 102A. For example, the control unit 30 can control the drive signal (or the pen drive signal) input. 0 indicates the first driving circuit among the driving circuit units 310 connected to the second patterns 102A. The second driving circuit is controlled so that a pulse signal of a predetermined frequency is output. The third driving circuit section controls so that no pulse signal is output from the An inverted pulse signal having a phase opposite to that of the pulse signal output from the first driving circuit is output. In this case, the second power supply may be electrically connected to the first driving circuit. A current loop is formed between the turn and the second pattern electrically connected to the third driving circuit unit. The current loop thus formed generates a magnetic field, which draws the sensor unit 100A closer to the sensor unit 100A. The stylus pen may be driven.

[0425] The control unit 300 includes a plurality of driving circuit units electrically connected to the second patterns 102A. 310, so that two 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 can change the setting of the sensor unit 100A to the state where the sensor unit 100A is located. When the position of the stylus is detected, two second patterns are generated around the position of the stylus. The driving circuit unit electrically connected to the driving circuit unit outputs 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 02A. It is also possible to control the output of the pulse signals opposite to each other.

[0426] 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 for explaining 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.

[0427] 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. Figure 25 shows 84 second patterns, two by two. It is composed of 42 channels, Ch0, Ch1, ..., Ch41, linked together.

[0428] For example, if the stylus pen 50 is connected to one of the 42 channels Ch0, Ch1, ..., Ch41, When the sensor is located between the second channel Ch2 and the third channel Ch3, the control unit 300 selects the style Based on the Rasp Pen 50, one or more channels located on the second channel Ch2 side drive the pen. The stylus pen 50 is controlled so that a signal is output from 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 The control can be performed so that the

[0429] In the stylus sensing mode (or the stylus downlink mode), the control unit 30 0 is a multiple sensing circuit unit 330 for stylus sensing in multiple of the sensor unit 100A. The first pattern 101A and the third pattern 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 The conductive pattern connected to the third pattern 103A is electrically connected to a plurality of sensing circuit units 330. can be linked to

[0430] The touch input device 500 according to the embodiment of the present invention has the following features: In the stylus sensing mode, a number of images are 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.

[0431] 26(a) to (f) show the touch input device of FIG. 24 in stylus sensing mode. 1 is a diagram for explaining the operation principle of a laser diode.

[0432] FIG. 26(a) shows one of the first patterns 101A shown in FIG. 24 and a 3 is a schematic model circuit diagram of a sensing circuit unit 330 of an electrically connected control unit 300. FIG. 26(b) shows a second pattern 101A disposed inside any one of the first patterns 101A. FIG. 26(c) is a circuit diagram showing a schematic model of the pattern 102A. FIG. 26(d) is a voltage distribution graph for the circuit diagram of FIG. 26(b). 1 is a graph showing voltage distribution in a circuit diagram.

[0433] 26(a) and 26(c), the sensing circuit unit 330 is disposed on the first pattern 101A. If the stylus pen approaches any point A 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, so 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.

[0434] 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. As the equivalent capacitance increases on the left side, 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 due to the equivalent resistance, and Vemf remains the same. It takes.

[0435] Comparing (c) and (d) of FIG. 26, the first pattern 101A and the second pattern 10 It can be confirmed that there is a potential difference of about Vemf between 2A and any position. The potential difference between the first pattern 101A and the second pattern 102A is about Vemf. Capacitive coupling between the first pattern 101A and the second pattern 102A The capacitive coupling causes the following phenomenon, as shown in FIG. As shown in FIG. 1, 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 by the turn 101A itself gradually becomes smaller, but the current generated by the second pattern 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 by using the touch panel.

[0436] As can be seen from (a) to (e) of FIG. 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 sensed on the sensor unit 100A. The control unit 300 receives the output from the sensing circuit unit 330 regardless of whether the sensing circuit unit 330 is close or far away. The stylus pen can be sensed from a certain signal output.

[0437] 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 was explained that the current flowing through the slit is due to capacitive coupling, but this is not the only mechanism. For example, the current flowing from the second pattern 102A to the first pattern 101A is This is also possible by magnetic coupling.

[0438] The principle of (a) to (e) of FIG. 26 described above is that the third part in any one of the second directions This also applies to the turn 103 and the fourth pattern 104. The same is also applied to the touch input device according to the first embodiment.

[0439] FIG. 26(f) is a modeled version of the second pattern 102A shown in FIG. 26(b). 11 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) shows a case where the sensing circuit unit 330 of the unit 300 is connected. Comparing (d) and (f) of Figure 26, the current is reduced by the equivalent resistance as you go 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 pattern and the second pattern cannot be maintained as much as Vemf, so the second pattern Therefore, the current cannot be transferred to the first pattern. The further away the sensor is, the less current the first pattern will output. In the singular mode, one end of the second pattern 102A is left open and floating. is preferred.

[0440] The size of the screen of the touch input device shown in FIG. 26 is the same as that of a smartphone screen, e.g. For example, if the display is 6.9 inches, there is no particular problem. However, if the display is 6.9 inches, the touch input device shown in FIG. 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 is increased, the capacitance of the sensor part 100A is also increased. The increase in the resistance and capacitance of 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 causes a problem in that the operating frequency bandwidth required for the design cannot be obtained.

[0441] In addition, the pen sensing signal received from the stylus pen is also increased due to the enlargement of the sensor unit 100A. In particular, the part of the sensor unit 100A 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 reduced to the extent required by the design. There is a problem in that the voltage value cannot be output.

[0442] In the following, a touch input device that can solve the above problems will be described.

[0443] FIG. 27 is a diagram showing an embodiment of the touch input device shown in FIG.

[0444] 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''.

[0445] The sensor unit 100A'' has a number of first to fourth patterns 101A, 102A'', Here, the multiple first, third and fourth patterns 101A, 10 3A, 104A are a number of 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.

[0446] 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.

[0447] 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.

[0448] The other ends (second side ends) of the multiple second patterns 102A'' are electrically connected to the conductive pattern. One end is relatively close to the control unit 300, and the other end is relatively It is far from Gobe 300.

[0449] The operation mode of the touch input device 500'' shown in FIG. 27 will now be described in detail.

[0450] 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 electrodes of the sensor unit 100A''. The control unit 300 can be electrically connected to the pattern 101A. 10A to drive a plurality of driving circuit parts 102A and 102B. 310 can be electrically connected to the

[0451] In addition, the control unit 300 has a number of sensing circuits 330 for sensing the touch position. The third patterns 103A of the sensor portion 100A'' may 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 may be electrically connected to a number of sensing circuit units 330 .

[0452] In this touch driving / sensing mode, the control unit 300 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 control units 300 electrically connected to the plurality of third patterns 103A receive the signal. The sensing circuit converts information on the amount of capacitance change 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.

[0453] Antenna drive mode (or stylus drive mode, or stylus uplink mode) At this time, the control unit 300 controls a number of driving circuits 310 for driving the antennas in the sensor unit 10. 0A'' may be electrically connected to a plurality of second patterns 102A''. 300 controls a number of switches to generate a number of conductive elements connected to the second pattern 102A''. The functional patterns can be electrically connected to a number of driving circuit units 310 .

[0454] 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 opposite pulse signals. Therefore, the control unit 300 can change and set the size and position of the current loop in various ways. It is possible.

[0455] 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. This is different from .

[0456] The control unit 300 controls a number of switches to generate a number of second patterns 101A'' and The conductive pattern connected to the third pattern 103A is electrically connected to a plurality of sensing circuit units 330. can be linked to

[0457] The touch input device 500 ″ shown in FIG. 27 is different from the touch input device shown in FIG. In comparison, a large number of 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 The control unit 300 is connected to the second conductive pattern 1 shown in FIG. 02A″ are each connected to the control unit 300 by a conductive pattern. Due to certain structural features, the touch input device 500'' shown in FIG. 27 is similar to the touch input device 500 shown in FIG. Although it has a disadvantage of having more channels than the input device 500, it is possible to drive a stylus pen. In the antenna drive mode, the pen drive signal is generated only at the specific area where the stylus pen is located. Since a signal can be applied, there is an advantage that power consumption can be reduced.

[0458] In addition, the touch input device 500 shown in FIG. 24 is a stylus input device 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 first pattern 101A is arranged in the short axis direction S, and the second pattern 103A is arranged in the short axis direction S. The illustrated touch input device 500'' is in a stylus sensing mode. A pattern for detecting a signal emitted from the '' and in the short axis direction S are a number of third patterns 103A.

[0459] In the touch input device 500″ shown in FIG. 27, in the stylus sensing mode, Then, a pattern in the longitudinal direction L that detects the signal emitted from the stylus pen is formed on 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 more suitable for sensing the touch position. To improve the operating frequency bandwidth of the touch drive signals and the 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.

[0460] In addition, in stylus sensing mode, the pen detection signal from the stylus pen is sent to multiple The control unit 300 receives the pen detection signal via the second pattern 102A''. In particular, in the longitudinal direction L, the voltage value of the control unit 300 is the most 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), 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 No. 27 has a second pattern 102 that 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.

[0461] In addition, since each of the multiple second patterns 102A'' is composed of one channel, When a number of second patterns 102A'' are used as driving electrodes (Stylus TX), The spacing between channels is reduced by half compared to 24 touch input devices, improving the driving resolution. There is a point.

[0462] FIG. 28 is a diagram showing an embodiment of the touch input device shown in FIG.

[0463] Referring to FIG. 28, a touch input device 500''' includes a sensor unit 100A''' and a front The sensor unit 100A'' may include a control unit 300 for controlling the sensor unit 100A''.

[0469] In the touch driving / sensing mode, the control unit 300 detects the touch of an object such as a finger. In order to sense the position, a number of driving circuit units 310 are provided on a number 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 pattern 101A are connected to a plurality of driving circuits by controlling the switches. The unit 310 may be electrically connected to the

[0470] In addition, the control unit 300 has a number of sensing circuits 330 for sensing the touch position. The third patterns 103A of the sensor portion 100A'' may be electrically connected to the third patterns 103A of the sensor portion 100A''. 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 circuitry 330 .

[0471] In this touch driving / sensing mode, the control unit 300 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 control units 300 electrically connected to the plurality of third patterns 103A receive the signal. The sensing circuit converts information on the amount of capacitance change 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.

[0472] Antenna drive mode (or stylus drive mode, or stylus uplink mode) At this time, the control unit 300 controls a number of driving circuits 310 for driving the antennas in the sensor unit 10. 0A''' may be electrically connected to a number of fourth patterns 104A'. 300 controls a number of switches to generate a number of conductive elements connected to the fourth pattern 104A'. The patterns can be electrically connected to a number of driving circuit units 310 .

[0473] The control unit 300 controls the driving circuits 310 connected to the fourth pattern 104A'. The control unit 300 can control the drive signal (or the pen drive signal) to be output. Any one of the driving circuits 310 electrically connected to the fourth patterns 104A' is 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.

[0474] 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 a sensor unit 100A''' 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.

[0475] 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 fourth pattern 104A' are electrically connected to a plurality of sensing circuit units 330. They can be linked together.

[0476] 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 TA1 shown in FIG. 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 many second patterns 102A are not used, many second patterns 1 There is no conductive pattern connected to one end of 02A. Therefore, This has the advantage that the thickness can be significantly reduced relatively compared to FIG.

[0477] 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 is somewhat increased, the number of patterns can be increased by using the stylus pen through the fourth patterns 104A'. Since the pen detection signal is directly received from the controller 300, the voltage of the pen detection signal received by the controller 300 is The advantage is that the value is larger. The advantage is that the voltage value of the detection signal is approximately twice as large as the detection signal.
