Description
[Technical Field]
[0001] The present disclosure relates to a controller, and more particularly to a controller including a sensor unit and a stylus. To control a sensor portion in a pen and touch input device that can interact with a pen This invention relates to a system and a controller. [Background technology]
[0002] Mobile phones, smartphones, laptops p computer), digital broadcasting terminal, PDA (personal digital assistant) al assistants), PMP(portable multimedia p layer), navigation, slate PC, tablet PC ( tablet PC, Ultrabook, wearable device Various touch input devices, such as wearable devices, have touch sensors. It can be prepared.
[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 classified as active (a) depending on whether it has a battery and electronic components inside. Stylus pens are divided into active and passive stylus pens. obtain.
[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 an inductive resonance method called E MR (Electro Magnetic Resonance) and Capacitive A (capacitive) resonance type technology has been proposed.
[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. Summary of the Invention [Problem to be solved by the invention]

[0013] Also, it solves the problem that the output voltage of the sensing circuit changes depending on the position of the stylus pen. The touch input device includes a controller device for controlling the sensor unit. A pen and touch input system is provided.
[0014] Also, when the screen of the touch input device is enlarged to the size of the tablet PC screen, It is possible to widen the operating frequency bandwidth of the touch and pen drive signals. In the touch input device, a pen including a controller device for controlling the sensor unit is provided. and a touch input system.

Describe in detail pen and touch input systems, including stylus pens that can To do so.
[0144] FIG. 1a shows a pen and touch input system including a stylus pen and a touch input device. This is a conceptual diagram.
[0145] 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 (or downlinks) signals to the touchscreen 20. Here, the touch input device 2 can be connected to a sensor. The controller controls the sensor and the stylus pen 10. It may also be named "computer and touch input device."
[0146] FIG. 1b shows the uplink in the pen and touch input system shown in FIG. 1a. 1 is a diagram for explaining a link and a downlink.
[0147] Referring to the left side 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. See the right side of Figure 1b. In the downlink, the electromotive force (V1 or Vemf) is measured at the sensor part of the touch screen 20. That is, the coil inside the stylus pen and the sensor part of the touch input device are It works with transformers.

[0149] 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.
[0150] FIG. 2 is a diagram illustrating a signal transmission operation between a stylus pen and a touch input device. is.
[0151] Referring to FIG. 2(a), the touch screen 20a includes a digitizer 29, a display The display panel 251 includes a sensor unit 21 and a window 22.
[0152] Among passive stylus pens, EMR (Electro-Magnetic Resonance) In the case of an EMR pen, the digitizer 29 is When a magnetic signal B is transmitted to the stylus pen 10a, a resonance signal is generated in the stylus pen 10a. The circuit resonates with the magnetic signal B. Then, the digitizer 33 receives the magnetic signal B from the stylus pen 10a. Receives resonated magnetic signal B as input.
[0153] 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 The magnetic field generated by the antenna loop is blocked by the antenna loop. The foil blocks eddy currents that may be generated in other electrical elements and components when the foil forms a magnetic field. Includes a ferrite sheet.
[0154] 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.
[0155] 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.
[0156] Referring to FIG. 2(b), the touch screen 20b includes a display panel 251, It includes a sensor unit 21 and a window 22 .

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 electrodes) of the sensor part 21 are made of a metal mesh with low resistance. When a magnetic turn is formed, a magnetic signal from the stylus pen 10 can be detected.
[0158] 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.

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).
[0161] 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.
[0162] 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.
[0163] 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 touch electrodes for detecting touch coordinates in a second direction intersecting the first direction; Although the sensor unit 21 is shown in one layer in FIG. The first touch electrode and the second touch electrode may be located on different layers, or may overlap each other. The first touch electrode and the second touch electrode may be overlapped or not overlapped. An additional layer may be interposed between the electrode and the conductive layer, but is not limited thereto.
[0164] Referring to FIG. 2(d), the touch screen 20d includes a display panel 251, It includes a sensor unit 21 and a window 22 .
[0165] 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 layer capacitors) for storage Resonance is achieved by using a capacitor (such as a layered capacitor) Then, the electrodes of the sensor unit 21 receive the resonated electromagnetic signal (E and / or B) can receive the input. The sensor part 2 is made of a metal mesh with low resistance. When one electrode (or pattern) is formed, the magnetic signal from the stylus pen 10' The active stylus pen 10' resonates to generate an electromagnetic signal. Not only circuits, but also power sources are used to generate electromagnetic signals (E and / or B) with a given frequency. The active stylus pen 10' may include a circuit for outputting a predetermined voltage. It may include any circuit that outputs an electromagnetic signal (E and / or B) having a frequency.
[0166] The touch screen 20d can be used to write a style without transmitting a magnetic signal to the stylus pen 10'. The touch screen 20 can receive electromagnetic signals from the pen 10'. d is for generating a signal for resonating the resonant circuit included in the stylus pen 10'. Since no additional units or modules are required, the touch screen 20d is thinner. It can be miniaturized and has advantages in terms of power consumption and manufacturing costs.

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.

[0202] FIG. 5 specifically illustrates the inductor portion of the stylus pen shown in FIGS. 4(a) and 4(b). This is a conceptual diagram.
[0203] Referring to FIG. 5, the inductor section 14 includes a ferrite core 115 and a ferrite core 116. 15 includes a wound coil 116.
[0204] At this time, the inductance of the inductor section 14 is expressed by the following equation: > is determined by.
[0205]
number
[0206] As can be seen from <Equation 1>, the inductance (L) is determined by the magnetic permeability of the ferrite core 115. The permeability is proportional to the cross-sectional area of the coil 116 and the number of turns. The winding length of the coil 116 is inversely proportional to the winding length.
[0207] 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 Q=2nfL / R 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.
[0208] In the design of the stylus pen shown in (a) and (b) of FIG. 4, L is the length to be used. It has a self-resonance frequency that is large enough for the frequency The Q value should preferably have a maximum value at the frequency to be used. To achieve this, the material of the ferrite core, the type of coil wire, and the winding method ( The diameter of the thin pen must be optimized. What is needed is a way to obtain a high output signal while maintaining a high power density.
[0209] In the following embodiments, various ferrite core materials, coil wire types, and winding methods are used. The most optimized stylus pen design method among the winding schemes We will explain about this.
[0210] (1) Ferrite core material The material of the ferrite core used in this embodiment is manganese (Mn), nickel (N i) was used.
[0211] (2) Wire type The types of coil wire used in this embodiment were enameled wire and Litz wire. .
[0212] 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.
[0213] As shown in FIG. 8, the Litz wire 200 is a thin insulating wire with a diameter of about 0.1 mm. A plurality of wires 100 (for example, enameled wire) are twisted together to form a single wire, and nylon is then 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 of high frequency circuits.
[0214] 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.
[0215] (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.
[0216] 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. Sequential layer winding method (sequential layer winding s In this case, the (A) method in Figure 9 is directly above the point where the winding of the previous layer ends. This is the method in which the winding of the layer begins, and will be referred to as the U-type winding method hereinafter.
[0217] The winding method shown in FIG. 9(B) is a method in which adjacent winding layers are wound alternately (alternate layer winding scheme, in which adjacent layers of windings are jig- This is a method in which the wire is wound in a zigzag pattern. Specifically, the second layer is wound on top of the first layer, and then the third layer is wound. After winding between the first and second layer windings and winding the fourth layer winding on top of the second layer winding This method involves winding the fifth layer of winding between the second and fourth layers of winding. The zag-type winding method can minimize the voltage difference between the windings on adjacent layers, Reduce winding self-capacitance At this time, the winding self-capacitance, which is a type of parasitic capacitance, Capacitance is the electric field energy stored in the winding. This is a parameter indicating the energy.
[0218] Comparative experiment 1 (comparison of material characteristics) 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.
[0219] 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.
[0220] 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 with enameled wire and Litz wire, respectively. The Q value of Inductor 2 was measured.
[0221] Figure 8 shows the E4980A precision oscilloscope from KEYSIGHT TECHNOGIES. Inductor 1 and inductor 2 measured by changing the frequency through an LCR meter 10 is a diagram showing the Q value of the capacitor 2.
[0222] 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.
[0223] 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).
[0224] 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.
[0225] However, the maximum Q value of inductor 2 measured in comparative experiment 2 was also below the target value (Q This was only about half the target.
[0226] Comparison experiment 3 (comparison of characteristic values by winding method) The ferrite core material is manganese (Mn), and the wire type is enameled wire. Three inductors were manufactured using Litz wire with different winding methods: U-type and zigzag type. The Q value of inductor 5 was measured.
[0227] Figure 11 shows the E4980A precision amplifier from KEYSIGHT TECHNOGIES. The inductor 3 or 4 was measured by changing the frequency through an LCR meter. 10 is a diagram showing the Q value of the inductor 5.
[0228] 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.
[0229] 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.
[0230] 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.
[0231] However, the inductor 5 (manganese core / litz wire / zigzag tube) measured in Comparative Experiment 2 The level is only about 3 / 4 of the target value (Qtarget) required for commercialization of the 1000kJ / semi-winding method. It was.
[0232] 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.
[0233] 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.
[0234] 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.
[0235] 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.
[0236] 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.
[0237] Important physical properties of manganese and nickel, which are primarily used as ferrite core elements The property is the permeability, which is the inductance as in equation 1. However, manganese and nickel as ferrite elements have a significant effect on the resistance value. In In fact, in the case of nickel, there is so little relevant information even in the data sheets provided by manufacturers. is.
[0238] In this embodiment, in order to check the dielectric constant of manganese and nickel, KEYSIGHT We used the E4980A precision LCR meter from TECHNOGIES. The permittivity of manganese and nickel was measured using The results are shown in Table 1 below.
[0239] [Table 1]
[0240] Measurements 1 and 2 were performed using the same KEYSIGHT TECHNOGIES E4980A. Measurement 1 was measured using a precision LCR meter. The dielectric constant calculated automatically by the measurement software is shown. Measurement 1 shows the dielectric constant of manganese. It is noted that the dielectric constant of nickel is not measured, although the dielectric constant is 2400.
[0241] 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.
[0242] 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.
[0243] 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.
[0244] Figure 12 shows the E4980A precision amplifier from KEYSIGHT TECHNOGIES. Inductor 6 and inductor 7 were measured by changing the frequency through an LCR meter. 10 is a diagram showing the Q value of Kuta 7.
[0245] In Figure 12, a is inductor 6 (nickel core / litz wire / U-type winding method) is the 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).
[0246] 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.
[0247] On the other hand, inductor 7 (nickel core / litz wire / zigzag tie) measured in comparative experiment 4 The maximum Q value of the coil winding method almost reaches the target value (Qtarget) required for commercialization. I found out that...
[0248] In the comparative experiments 1 to 4 described above, the material of the ferrite core, the type of wire of the coil, By changing the combination of type and winding scheme, inductors The results of the test showed that the Q value was 100% for nickel core, Litz wire, and zigzag type. The highest inductance is obtained when the inductor part of the capacitive resonant stylus pen is designed using a wire-wound method. It was found that the Q value could be obtained. It was found that the maximum Q value of the FET reaches the target value (Qtarget) for commercialization.
[0249] 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 were obtained when using wires wrapped around the strands. It will be possible.
[0250] 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. The output voltage (V Explain why the value of "out" changes.
[0251] FIG. 13 shows the CVA (C The output voltage (Vout) of the apacitor voltage amplitude changes. 1 is a schematic diagram for explaining the division.
[0252] 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
[0253] Metal Mesh touch screen based on the long axis of a conventional touch screen The resistance (R) of the sensor is about 1.2k (ohm), and the capacitor (C) is about 250p It's F.
[0254] Based on 10 distributed models, the driving frequency is 30 At 0 kHz, the capacitor impedance ) is about 200 times the resistance (120 (ohm) vs. 1 / (2π*300k*25pF) = 21k(ohm)). Therefore, the capacitor is the main This is the cause.
[0255] FIG. 14 shows the output voltage (Vout1) of the CVA depending on the position of the stylus pen 10 in FIG. , Vout2) are different. 13.) and FIG. 15 is a diagram for explaining the position of the stylus pen 10 in FIG. Therefore, the voltage sensing detects that the output voltages (Vout1, Vout2) of the CVA are different. 1 is a diagram for explaining through voltage sensing.
[0256] 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.
[0257] 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.
[0258] 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.
[0259] The touch input device according to the first embodiment of the present invention is a portrait type. Such a portrait-type touch input device may be a portrait-type touch input device. , the width is smaller than the height, and a control unit (not shown) that controls the sensor unit 100 For example, such a touch input device may be configured in the shape of a smartphone. handle.
[0260] 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.
[0261] The sensor unit 100 includes a large number of patterns (or a large number of electrodes).
[0262] The sensor unit 100 has a number of first to fourth patterns 101, 102, 103, and 104. It may include.
[0263] 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 formed along an arbitrary first direction y. The electrical pathway may have a predetermined shape.
[0264] 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). The pattern 101 has a predetermined shape in which an electrical path is formed along the first direction y. That's fine.
[0265] 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 third pattern 103 has a predetermined shape in which an electrical path is formed along an arbitrary second direction x. may have
[0266] 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). The turn 103 has a predetermined shape in which an electrical path is formed along the second direction x adjacent to the turn 103. good.
[0267] 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.
[0268] 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.
[0269] 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 .
[0270] 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.
[0271] 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. Metal Mesh or Silver Trace ) may be.
[0272] 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.
[0273] 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.
[0274] 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.
[0275] 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.
[0276] 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 transmitted to the third patterns 103. It can operate on receiving touch sensing electrodes (RX electrodes, or touch receiving electrodes). Of course, it can also work the other way around.
[0277] The sensor unit 100 of the touch input device shown in FIG. 16 drives the stylus pen. In order to perform sensing by detecting the first to fourth patterns, 101, 102, 103, and 104 may be used in various combinations. The combination is as shown in Table 2 below. In Table 2 below, "1" indicates the first pattern of many. "2" represents a number of second patterns 102; "3" represents a number of third patterns 103; 3 and "4" indicates a number of fourth patterns 104.
[0278] [Table 2]
[0279] Referring to Table 2 above, in various combinations (No. 1 to No. 32), many The first pattern 101 of numbers and the third pattern 103 of numbers are formed by touching an object such as a finger. Specifically, the first patterns 101 are used for sensing touch. The third pattern 103 acts as a touch receiving electrode. Well, the opposite is also possible.
[0280] 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.
[0281] At least one of the first to fourth patterns 101, 102, 103, and 104 Or two, a sensor that senses the 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 can be used from patterns 101, 102, 103, and 104. 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 large number of third patterns 103 and a large number of fourth patterns 104. It may be either one.
[0282] In the above Table 2, "uplink signal strength" refers to the signal strength shown in Figure 1a. It means the magnitude of the drive signal for driving the stylus pen 10. A pen driving signal is applied to the first patterns 101 and the second patterns 102. When comparing the signal strength received by the stylus pen, we see that there are many second patterns. When a stylus pen driving signal is applied to the first pattern 101, the stylus pen is driven by the first pattern 101. The uplink signal is relatively larger than when the pen drive signal is applied.
[0283] 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 first pattern 101 is charged, one end (or the first The current cannot flow well from the other end (or the first end) to the other end (or the second end). In addition, the stylus pen driving signal applied through the first patterns 101 is capacitive. The current is transmitted to a number of second patterns 102 in which current loops are formed via reactive coupling. However, at this time, signal attenuation occurs due to capacitive coupling.
[0284] 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.
[0285] In the above Table 2, "downlink signal magnitude" refers to the 1a indicates the magnitude of the stylus signal received from the stylus pen 10. stylus pen signals are transmitted through a number of first patterns 101 and a number of second patterns 102. When the magnitudes of the received signals are compared, it is found that the signals are transmitted through a large number of second patterns 102. When a stylus pen signal is received, the stylus pen is The downlink signal is relatively louder than the received signal.
[0286] 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.
[0287] 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.
[0288] In the above table 2, "Stylus additional channel" refers to the touch sensor Do I need to configure an additional channel for the stylus besides the sensing? This means driving and sensing the stylus pen. When multiple second patterns 102 or / and multiple fourth patterns 104 are used for On the other hand, the stylus space requires an additional channel (shown as "Yes" in Table 2). A plurality of first patterns 101 and / or When the third pattern 103 is used, no additional channel is required ("None" in ). (shown as ).
[0289] Below are some of the various combinations (No. 1 to No. 32) in Table 2 above. Examples are described in detail below, where combinations not described will be considered as such in the detailed description below. , as will be well understood by those skilled in the art.

The touch sensing electrode is used for the touch sensing of the stylus pen signal. It is used as a stylus sensing electrode for sensing. The capacitor 104 is electrically floating. 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.

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 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 determined by the stylus pen contact. The pattern selected may differ from the pattern selected when the When the stylus pen is in a hover state, the control unit (not shown) controls the first and second patterns.

[0315] 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.
[0316] The touch input device according to the second embodiment of the present invention is a landscape ) type touch input device. Such a landscape type touch input device , the width is greater than the height, and a control unit (not shown) that controls the sensor unit 100' is For example, such a touch input device may be in the form of a tablet PC. It can respond to the situation.
[0317] 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.
[0318] 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.
[0319] 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 number of channels of the sensor unit 100' is Number of trace channels (TX Trace Channel) and the number of trace channels (TX Trace Channel) The number of items (l) can be roughly summarized as shown in Table 3 below.
[0320] [Table 3]
[0321] In the above table 3, the number of channels of Stylus TX is a number of first patterns 1 The number of second patterns 102 is the number of 01 divided by 2. Although the number of the first patterns 101 is the same, as shown in FIG. The ends (first end portions) of the turns 102 are electrically connected to each other. This is due to the number of channels being reduced by half.
[0322] In the above table, the number of TX Trace channels is The sum of the number of X channels and the number of Stylus TX channels. TX Trace The number of channels is determined by the width direction bezel of the touch input device according to the second embodiment. This is the main factor that determines the thickness of the second embodiment. The touch input device has a control unit (not shown) located below (or above) the sensor unit 100'. The more the number of TX Trace channels is reduced, the faster the touch input becomes. The widthwise bezel thickness of the force device can be reduced.
[0323] 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 The operating frequency bandwidth of the stylus driving signal for driving the pen is Therefore, there may be a problem that the required operating frequency bandwidth for the design cannot be obtained. To solve this problem, it is 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. Even if this value is reduced to the maximum, The problem still cannot be solved.
[0324] 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.
[0325] 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.
[0326] 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 channels (To Number of trace channels (TX Trace Channel) and driving trace channels (TX Trace Channel) The number of nel) is summarized in Table 4 below.
[0327] [Table 4]
[0328] In the above Table 4, the number of channels of Stylus TX is a number of the second pattern 102. This means that the number of second patterns 102 is equal to the number of first patterns 103. 21, the number of the second patterns 102 is the same as the number of the first patterns 102. Each of these is due to being individually connected to one conductive pattern.
[0329] In the above table, the number of TX Trace channels is The sum of the number of X channels and the number of Stylus TX channels. TX Trace The number of channels determines the thickness of the bezel on the minor axis of the touch input device. Reducing the number of TX trace channels reduces The thinner the bezel, the thinner the thickness of the bezel on the minor axis of the touch input device.
[0330] 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.
[0331] 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) In addition, the spacing between channels is reduced by half compared to the example in , so the resolution of the stylus drive is There is an advantage to improving.
[0332] 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 entire channel ( Total Channel) and the number of driven trace channels (TX Trace Ch The number of channels is summarized in Table 5 below.
[0333] [Table 5]
[0334] In the above table, the number of channels for Stylus TX is 1. The number of fourth patterns 104 is the same as the number of third patterns 104. 22, the number of the fourth patterns 104 is the same as the number of the fourth patterns 103. This is because each end is individually connected to one conductive pattern.
[0335] In the above table, the number of TX Trace channels is The number of TX Trace channels is the same as the number of X channels. This is the primary factor that determines the thickness of the bezel on the minor axis of the device. X The fewer the number of trace channels, the better the short axis of the touch input device will be. The thickness of the gel can be reduced.
[0336] 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.
[0337] 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), The spacing between channels is reduced by half compared to the example in Table 3, which has the advantage of improving the driving resolution.
[0338] 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.
[0339] FIG. 23 is a schematic diagram showing a configuration of yet another example of the sensor unit 100′ shown in FIG. Figure.
[0340] 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.
[0341] 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'.
[0342] 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.
[0343] 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.
[0344] 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 channels of the sensor unit 100'' are nnel) and the number of driving trace channels (TX Trace Channels) The results are summarized in Table 6 below.
[0345] [Table 6]
[0346] In the above table 6, the number of channels of Stylus TX is a number of second patterns 1 The number of second patterns 102' is divided by 2. The number of the first patterns 101' is the same as the number of the second patterns 102'. This is because two adjacent second patterns are electrically connected to each other.
[0347] In the above table, the number of TX Trace channels is The sum of the number of X channels and the number of Stylus TX channels. TX Trace The number of channels determines the thickness of the width direction bezel of the touch input device. Reducing the number of TX trace channels reduces The thinner the bezel, the thinner the thickness of the bezel on the minor axis of the touch input device.
[0348] 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.

[0382] The control unit 300 controls the sensor unit 100A in touch drive / sensing mode, antenna drive It is limited to operate in either mode, or stylus pen sensing mode. The control unit 300 controls a number of driving / sensing circuit units 310 according to each mode. , 330 can be electrically and selectively connected to the sensor unit 100A for control. To this end, the control unit 300 controls a number of driving / sensing circuit units 310, 330 and the sensor unit 100A.
[0383] 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. .
[0384] 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
[0385] 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 unit 300 controls a number of switches to connect a number of conductive electrodes connected to the third pattern 103A. The pattern can be electrically connected to multiple sensing circuit units 330 .
[0386] 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.
[0387] Meanwhile, in the touch driving / sensing mode, a plurality of first patterns 101A and a plurality of second patterns Capacitive coupling between turn 102A In order to prevent this, the control unit 300 assigns a number of second patterns 102A to the number of second patterns 102A. The control unit 300 can electrically connect the driving circuit unit 310. The same driving signal as that applied to the first pattern 101A is applied to a large number of second patterns 10 Alternatively, the control unit 300 may control the first pattern to be applied to the first pattern 2A. When a driving signal is applied to the pattern 101A, a predetermined It is also possible to control the voltage so that a fixed reference potential is applied.
[0388] 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 to a plurality of second patterns 102A. , controlling a number of switches to form a number of conductive patterns connected to the second pattern 102A. It can be electrically connected to a plurality of driving circuits 310 .
[0389] The control unit 300 controls the output from each of the driving circuits 310 connected to the second patterns 102A. 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.
[0390] 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.
[0391] 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.
[0392] 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.
[0393] 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 selects the style 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 is possible to control the amount of heat generated.
[0394] 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
[0395] 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.
[0396] 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.
[0397] 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.
[0398] 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, The equivalent capacitance of the first pattern 101A viewed from the outside is small, so the equivalent impedance Therefore, the induced voltage (Vemf) is mostly applied to the left side of point A. Therefore, a voltage close to 0 (V) is applied to the right side of point A, and almost no current flows. Moreover, the voltage close to 0 (V) on the right side of point A is Therefore, the voltage gradually decreases, and almost no voltage is applied to the input terminal of the sensing circuit unit.
[0399] Referring to (b) and (d) of FIG. 26, if an induced voltage (Vemf) occurs at point A, , the other end of each second pattern 102A is electrically connected to the left of point A, so that the other end of each second pattern 102A is electrically connected to the left of point A. Looking to the left of the point, the equivalent capacitance becomes larger, so the equivalent impedance becomes almost 0. Therefore, the left side of point A is applied with 0 (V), and the right side of point A is applied with the second pattern 1. Since one end of 02A is open, no voltage drop occurs due to the equivalent resistance. Well, Vemf will be applied.
[0400] 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 Vemf at any position between 2A and The potential difference of Vemf between the first pattern 101A and the second pattern 102A is The capacitive coupling (ca This causes capacitive coupling. As a result, as shown in FIG. 26(e), the second pattern 102A is transferred to the first pattern 10. The current of 1 A flows. The further away from 0, the smaller the current generated by the first pattern 101A itself becomes. However, since a current flows from the second pattern 102A to the first pattern 101A, The current output from the sensor 101A to the sensing circuit 330 of the control unit 300 is almost always proportional to the position of the pen. Therefore, the control unit 300 is electrically connected to the first pattern 101A. The position of the stylus pen can be sensed through the sensing circuit unit 330.
[0401] 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 as Vemf. Therefore, the position of the stylus pen on the sensor unit 100A is constant. The control unit 300 receives the signal from the sensing circuit unit 330 regardless of whether the signal is close or far from the sensing circuit unit. The stylus pen can be sensed from a constant signal that is input.
[0402] 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.
[0403] 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.
[0404] 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 from the first pattern to the second pattern. The further away from the stylus, the smaller the current output from the first pattern. In the sensing mode, one end of the second pattern 102A is left open and floating. It is preferable that
[0405] 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 larger than that of a smartphone (6.9 inches). This results in a problem in that the operating frequency bandwidth required for the design cannot be obtained.
[0406] 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 that the voltage value cannot be output.
[0407] The following describes a touch input device that can solve the above-mentioned problems.
[0408] FIG. 27 is a diagram showing a specific embodiment of the touch input device shown in FIG.
[0409] 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''.
[0410] 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 it is the same as 03A and 104A, the explanation for this will be omitted.
[0411] 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.
[0412] 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.
[0413] 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.
[0414] The operation mode of the touch input device 500'' shown in FIG. 27 will now be described in detail.
[0415] 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
[0416] 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 .
[0417] 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.
[0418] 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 .
[0419] 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.
[0420] 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.
[0421] 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
[0422] 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.
[0423] 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.
[0424] 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. Improved operating frequency bandwidth of touch drive and touch sense signals This improves the operating frequency bandwidth of the pen drive signal for driving the stylus pen. It can be done.
[0425] 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. Capacitive coupling between turn 102A Specifically, in the case of FIG. 24, (e) of FIG. 26 As described above, the capacity between the first pattern 101A and the second pattern 102A Current flows from the second pattern 102A to the first pattern 101A due to the coupling. Therefore, there is no attenuation of the pen sensing signal input to the control unit 300 via the first pattern 101A. However, the touch input device 500'' of FIG. 27 does not have the first pattern 101A. Directly connected to the control unit 300 via the second pattern 102A'' without capacitive coupling. Since the input is direct, there is no attenuation of the pen sensing signal due to capacitive coupling. .
[0426] 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), In this case, the spacing between channels is reduced to half that of the touch input device in Figure 24, improving the driving resolution. There is an advantage to it.
[0427] FIG. 28 is a diagram showing a specific embodiment of the touch input device shown in FIG.
[0428] Referring to FIG. 28, the 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'''.

[0434] 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 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 .
[0435] 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 .
[0436] 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. It can be output as a pressure value.
[0437] The control unit 300 processes the output voltage value to detect the touch position. Antenna drive mode (or stylus drive mode, or stylus uplink mode) At this time, the control unit 300 controls the sensor unit 100A to control a number of drive circuits 310 for driving the antennas. The control unit 30 may be electrically connected to a plurality of fourth patterns 104A'. 0 controls a number of switches to form a number of conductive patterns connected to the fourth pattern 104A'. The lamps may be electrically connected to a number of driving circuits 310 .
[0438] The control unit 300 controls the driving circuits 310 connected to the fourth patterns 104A'. The control unit 300 can control the drive signal (or pen drive signal) to be output. 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.
[0439] 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.
[0440] 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.
[0441] 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.
[0442] 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'. Since the pen sensing signal is directly received from the controller 300, the voltage of the pen sensing signal received by the controller 300 is The advantage is that the value is larger.

[0443] In addition, since each of the many fourth patterns 104A' is made up of one channel, When the fourth pattern 104A' is used as a driving electrode (Stylus TX), ,The spacing between channels is reduced to half compared to the touch input device of FIG. 24, and therefore the driving resolution is improved. This has the advantage of being
[0444] 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. This has the advantage of reducing the thickness of the bezel B.
[0445] FIG. 29 is a diagram showing a specific embodiment of the touch input device shown in FIG.
