Description

Technical Field

[0001] The present disclosure relates to a pen, a touch input system, and a controller, and more particularly to a touch input device including a sensor unit that can interact with a stylus pen, and a pen, a touch input system, and a controller for controlling the sensor unit.

Background Art

[0002] Various touch input devices such as mobile phones, smart phones, laptop computers, digital broadcast terminals, PDAs (personal digital assistants), PMPs (portable multimedia players), navigation devices, slate PCs, tablet PCs (tablet PCs), Ultrabooks, and wearable devices are equipped with touch sensors. In such touch input devices, the touch sensor can be located on a display panel that displays an image[[ID = 25]] [[ID = 26]]

[0003] [[ID = 27]] [[ID = 28]]or on a part of the touch input device. When a user touches the touch sensor to interact with an electronic device,[[ID = 29]] [[ID = 30]]the touch input device can provide an intuitive user interface to the user. [[ID = 31]] [[ID = 32]]For precise touch input, a user can use a stylus pen. The stylus pen can be classified into an active[[ID = 33]] [[ID = 34]](active) stylus pen and a passive stylus pen depending on whether it has a battery and electronic components inside. [[ID = 35]] [[ID = 36]]

[0004] [[ID = 37]] [[ID = 38]] [[ID = 39]] [[ID = 40]] [[ID = 41]] [[ID = 42]] [[ID = 43]]

[0005] Active stylus pens offer superior basic performance compared to passive stylus pens, and additional features are available. It has the advantage of being able to provide specific functions (pressure sensitivity, hovering, buttons), but the pen itself is expensive. It requires a power source and uses a battery charging system, so it's not practical for anyone other than a select group of high-end users. One disadvantage is that it is not used by many people.

[0006] Passive stylus pens are cheaper than active stylus pens, and battery life is low. It has the advantage of not requiring a touch, but it does not offer the same level of precise touch recognition as an active stylus pen. It has the disadvantage of being difficult to recognize. However, recently, sophisticated touch recognition has become possible with passive stars. To realize the illustration pen, the inductive resonance method EMR (Ele Two technologies have been proposed: the CTR Magnetic Resonance method and the capacitive resonance method. It is being done.

[0007] While the EMR method excels in the core function of a stylus pen—writing / drawing quality— In addition to the responsiveness touch panel, a separate EMR sensor panel and EMR driver IC are not included. Because it is necessary, it has the disadvantage of being thicker and costing more.

[0008] Capacitive resonant technology is a common method for capacitor touch sensors and touch controls. Using a Ra IC results in no additional costs, and the IC's performance is enhanced to even support pen input. This is the method.

[0009] In the EMR method or capacitive resonant method, the touch sensor is connected to a stylus pen. In order to more accurately identify the touch, the amplitude of the resonant signal must be large, and this Furthermore, the frequency of the drive signal transmitted to the stylus pen is determined by the resonance built into the stylus pen. The resonant frequency of the circuit should be made to be approximately the same. However, conventional EMR methods or capacitive According to the tibial resonant method, even if the resonant frequency and the frequency of the drive signal match, signal transmission attenuation occurs. The size is very large, which presents a problem in terms of signal transmission. As a result, many touch controls Despite years of effort by IC vendors, sufficient output signals are still not being produced, and mass production is still not possible. The reality is that no manufacturer has achieved success in this area.

[0010] Therefore, the EMR method or capacitive resonant sonar that can produce the maximum output signal To manufacture a tyrus pen, how do you design the internal resonant circuit and the structure of the pen? This becomes a very important factor.

[0011] On the other hand, among passive stylus pens, the EMR (Electro-Magnetic Resonance) type In this case, after the digitizer transmits a magnetic signal to the pen, the digitizer The digitizer receives a resonant signal input from the pen. Such digitizers receive touch information from the pen. A dense arrangement of coils is formed, in which a current can be induced by a magnetic signal in order to receive it. Such digitizers can accommodate the miniaturization and thinning of touch input devices. Furthermore, there is the problem that it cannot be designed flexibly.

[0175] Figure 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 Figure 1a, the stylus pen 10 is connected to the touchscreen 2 of the touch input device 2. Receive a signal output from the touch input device 2 or touchscreen 20 near 0 (or , uplink) and send a signal to the touchscreen 20 (or downlink) It is possible to (downlink). Here, the touch input device 2 consists of a sensor unit and a sensor unit It includes a control unit that controls the stylus pen 10 and interacts with it, so "pen and touch input" It could also be called a "force device."

[0177] Figure 1b shows the uplink in the pen and touch input system shown in Figure 1a. This is a diagram illustrating nk and downlink.

[0178] Referring to the diagram on the left in Figure 1b, the uplink is inside the stylus pen 10 in Figure 1a. An electromotive force (V2, or Vemf) is formed in the coil. Referring to the diagram on the right in Figure 1b, In Unlink, an electromotive force (V1 or Vemf) is generated at the sensor part of the touchscreen 20. In other words, the coil inside the stylus pen and the sensor part of the touch input device are transformers It operates using a transformer.

[0179] Figure 1c illustrates the spacing between the + drive channel and the - drive channel in the uplink. This is a drawing for clarity.

[0180] Referring to Figure 1c, in the uplink, between the + drive channel and the - drive channel The optimal spacing depends on the shape and position of the inductor inside the stylus pen. As a design criterion for typical stylus pens, the distance between the + drive channel and the - drive channel is It is preferable to widen the spacing between at least one channel (4 mm).

[0181] Figure 1d shows other examples of pen and touch input systems, including a stylus pen and a touch input device. This is a conceptual diagram showing the implementation method.

[0182] Referring to Figure 1d, the touch input device 2 is foldable. The laspen 10 touches the touch screen 20 of the foldable touch input device 2. The system receives a signal output from input device 2 or touchscreen 20, and the touchscreen 2 A signal can be sent to 0.

[0183] Rectangular foldable touch input device 2 or touch screen 20 included therein In the member, the long side located on the left side of the plane is the first long side LS1, and the long side located on the right side is the second long side The two longer sides are LS2, the shorter side located above is the first shorter side SS1, and the shorter side located below is the second shorter side S We will refer to this as S2.

[0184] The foldable touch input device 2 has four crossings that extend across the first short side SS1 and the second short side SS2. It bends along a predetermined folding direction, with the folding axis AXIS_F as the reference point. This is possible. In other words, the foldable touch input device 2 is based on the folding axis AXIS_F. As a general rule, the folded state and the unfolded state are shown. A transition between this state and the unfolded state may be possible.

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

[0186] Referring to (a) in Figure 2a, the touchscreen 20a is a digitizer 29, display It 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 total, the digitizer 29 transmits magnetic signal B to the EMR-type stylus pen 10a. When transmitted, the resonant circuit contained in the stylus pen 10a resonates with the magnetic signal B. Then, the digitizer 33 receives the input of a resonant magnetic signal B from the stylus pen 10a. .

[0188] The digitizer 29 may be attached to the underside of the display panel 251, and a conductive antarctic FPCB (Flexible Printed Circuit Board) and Antenna The magnetic field generated by the narloop is blocked, and when the antenna loop forms a magnetic field, other electricity Ferrite sheet that blocks eddy currents that can be generated in gaseous elements and components. ) includes.

[0189] The FPCB has multiple antenna loops to sense the location where the resonant signal is input. It consists of layers. One antenna loop is at least one other antenna loop. It has a form that is superimposed in the Z-axis direction. This results in a thick FPCB. When using the digitizer 29, it is difficult to make the touch input device 2 thinner and smaller.

[0190] Such a digitizer 29 is mounted on the foldable / flexible touch input device 2. In this case, the FPCB attached to the folding area will deform when folding occurs. This can occur in wiring components that form antenna loops due to repeated folding. Stress can be applied, eventually leading to damage to the wiring components. Ferrite sheets This blocks the influence of the magnetic field generated by the antenna loop on the inside of the touch input device 2. The ferrite sheet is also thick, and deformation occurs when the touch input device 2 is folded. It is prone to developing problems and can be damaged by repeated folding.

[0191] Referring to Figure 2a(b), the touchscreen 20b is the display panel 251 It includes a sensor unit 21 and a window 22.

[0192] In the case of the stylus pen 10 which includes a resonant circuit, the electrodes (or pattern) of the sensor part 21 are When a magnetic signal B is transmitted to the stylus pen 10, the resonant circuit contained in the stylus pen 10 activates. It resonates with magnetic signal B. When this happens, the electrodes (or patterns) of the sensor unit 21 become stylish The laspen 10 can receive input of resonant electromagnetic signals (E and / or B). The electrodes (or patterns) of the sensor part 21 are made of a metal mesh with low resistance. If formed, it is possible to detect the magnetic signal from the stylus pen 10.

[0193] Similarly, compared to the digitizer 29, the touchscreen 20b transmits magnetic signals to the stylus. Since it does not require any additional units or modules to transmit to the Spen 10, touch Screen 20b can be made thinner, and it also has advantages in terms of manufacturing costs.

[0194] Referring to Figure 2a(c), the touchscreen 20c has a loop coil 264, It includes a spray panel 251, a sensor unit 21, and a window 22.

[0195] In the case of the stylus pen 10 which includes a resonant circuit, the loop coil 264 is the stylus pen 10 When magnetic signal B is transmitted, the resonant circuit included in the stylus pen 10 resonates with magnetic signal B. This allows the electrodes (or patterns) of the sensor unit 21 to be connected to the stylus pen 10. It can receive input of a transmitted electromagnetic signal (E and / or B).

[0196] Compared to the digitizer 29, the loop coil 264 is a magnetic coil used to detect the touch position. Since it does not receive signal B, the wiring structure is simple and the touchscreen 20c can be made thinner. Yes. This makes it possible to make the touch input device 2 thinner and smaller. Also, loop coil 2 64 can be formed in various sizes and positions, so such touchscreens Lean 20c can also be applied to foldable / flexible touch input devices 2.

[0197] The loop coil 264 includes a substrate on which the antenna loop is located and a ferrite sheet. Good. The antenna loop may be formed from a conductive material such as copper or silver. The antenna loop is In addition to being located on the substrate, it can also be located on the same layer as the sensor unit 21, in which case the antenna loop High transmittance such as metal mesh, ITO, graphene, and silver nanowire It may be formed from a conductor material exhibiting low impedance. Also, the antenna loop is a win It can be located below the dow, 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. It may include (n). For example, the sensor unit 21 may include multiple for detecting touch coordinates in the first direction. A number of first touch electrodes and multiple touch coordinates for detecting touch in a second direction intersecting the first direction. It may include a second touch electrode. In Figure 2, the sensor part 21 is shown as a single layer. The first touch electrode and the second touch electrode may be located in different layers, and they may be located in different layers. They may be positioned superimposed on each other, or they may not be positioned superimposed on each other, the first touch electrode and the second A separate layer may be interposed between the touch electrode and the other electrode, but this is not limited to the case.

[0199] Referring to Figure 2a(d), the touchscreen 20d is the display panel 251 It includes a sensor unit 21 and a window 22.

[0200] In the case of the active stylus pen 10' which includes a resonant circuit, the active stylus pen 1 The resonant circuit included in 0' controls the power supply (for example, the power) within the active stylus pen 10'. Batteries (including secondary batteries) and EDLCs (electric double layered batteries) for storage. Resonance is achieved using a capacitor (such as a capacitor). Then, the electrodes of the sensor unit 21 The device receives an input of resonant electromagnetic signals (E and / or B) from the stylus pen 10'. This is possible. The electrodes (or patterns) of the sensor part 21 are formed with a metal mesh with low resistance. If so, it is possible to detect the magnetic signal from the stylus pen 10'. The Iraspen 10' uses a power supply as well as a resonant circuit to generate electromagnetic signals. It may include a circuit that outputs an electromagnetic signal (E and / or B) having a fixed frequency. Active Stylus Pen 10' has a resonant circuit and an electromagnetic signal (E and / ) having a predetermined frequency. Alternatively, it may include all circuits that output B).

[0201] The touchscreen 20d does not require the transmission of magnetic signals to the stylus pen 10'. Electromagnetic signals can be received from the laspen 10'. That is, the touchscreen 20 d is used to generate a signal to resonate the resonant circuit contained in the stylus pen 10'. Because it does not require any additional units or modules, the Touchscreen 20d can be made thinner. Furthermore, it can be miniaturized and has advantages in terms of power consumption and manufacturing costs.

[0238] Figure 4 is a diagram showing a stylus pen according to an embodiment.

[0239] The stylus pens in Figure 4 all include a resonant circuit section 12 within the housing.

[0240] The resonant circuit section 12 is an LC resonant circuit, and the output from the touchscreen 20 in Figures 2 and 3 It can resonate with the driving signal being applied. The driving signal is at the resonant frequency of the resonant circuit section 12. It may include signals with corresponding frequencies (e.g., sine waves, square waves, etc.). For this purpose, the resonant frequency of the resonant circuit section 12 and the frequency of the drive signal are the same or very similar. It must be. The resonant frequencies of stylus pens 10a and 10b are stylus pen 1 The design values ​​of the resonant circuit section 12 of 0a and 10b are followed. The sensor section 21 of Figure 2(b) or Figure 2 (c) If the loop coil 264 generates an electromagnetic field due to the drive signal, the stylus pen 1 The resonant circuit section 12 of 0a and 10b resonates using the signal received via the change in the magnetic field.

[0241] The elements of the stylus pens 10a and 10b may be housed in a housing. The housing is Cylinders, polygonal prisms, columnar forms with at least a curved surface, entasis forms, pyramidal pyramids Having a frustum of pyramid form, a circular truncated cone form, etc. However, it is not limited by its form. Because the housing is hollow inside, resonance occurs within it. It can accommodate elements of the stylus pens 10a and 10b, such as the circuit section 12. Such housings may be made of non-conductive materials.

[0242] As shown in Figure 4(a), the EMR type stylus pen 10a has a resonant circuit section 12 The resonant circuit section 12 includes an inductor section 14 and a capacitor section 13. 14 is a ferrite core 115 and a coil 11 wound on the outer surface of the ferrite core 115. Includes 6.

[0243] The EMR-type stylus pen 10a may further include a tip 11a. 'a' is the tip of the stylus pen 10a, and as shown in Figure 4(a), it is a ferrite It may be positioned to penetrate the core 115, and may protrude from the ferrite core 115. The tip 11a may be non-conductor, or conductor, for example, conductive metal. The electrode core may consist of a hard resin mixed with conductive powder. Here, tip 1 It is irrelevant whether 1a is electrically connected to the resonant circuit section 12.

[0244] The ferrite core 115 may be, for example, a cylindrical ferrite material. The core 115 has a predetermined diameter (e.g., 1 mm) for inserting and passing the chip 11a. Through holes in the axial direction may be formed. In addition, the ferrite core 115 may be cylindrical, multi prism, column form with at least a curved surface, barrel-shaped column form, truncated pyramidal form, truncated cone, truncated pyramid It may be formed in the form of a toroid, a ring, or other shapes.

[0245] The coil 116 can be wound along the entire length of the ferrite core 115 in the axial direction, It may be wound over a certain length. The coil 116 is electrically connected to the capacitor section 13. They are connected.

[0246] The capacitor section 13 may include multiple capacitors connected in parallel. Printed circuit board Each of the capacitors above may have different capacitances, and during the manufacturing process, trimming It is OK to trim it.

[0247] As shown in Figure 4(b), the ECR (Electrically Coupled Resonance) method The tyrus pen 10b includes a conductive tip 11b and a resonant circuit section 12. The resonant circuit section 12 is The inductor section 14 and the capacitor section 13 may be grounded. Part 14 comprises a ferrite core 115 and a coil 1 wound on the outer surface of the ferrite core 115. Includes 16.

[0248] The conductive chip (11b) is made of a conductive material (e.g., metal, conductive) in whole or in part. It may be formed from, but is not limited to, conductive rubber, conductive fabric, conductive silicone, etc. do not have.

[0249] The coil 116 can be wound along the entire length of the ferrite core 115 in the axial direction, It may be wound over a certain length. The coil 116 is electrically connected to the capacitor section 13. They are connected.

[0250] The capacitor section 13 may include multiple capacitors connected in parallel. Printed circuit board Each of the capacitors above may have different capacitances, and during the manufacturing process, trimming It is OK to trim it.

[0251] Figure 5 shows the inductor section of the stylus pen shown in Figures 4(a) and 4(b) in detail. This is the conceptual diagram shown.

[0252] Referring to Figure 5, the inductor section 14 consists of a ferrite core 115 and a ferrite core 1 Includes a coil 116 wound around 15.

[0253] At this time, the inductance of the inductor section 14 is given by the following <Equation 1> It will be decided. <Formula 1> As can be seen from TIFF0007898759000001.tif12137<Equation 1>, the inductance (L) is the permeability of the ferrite core 115. The permeability is proportional to the cross-sectional area of ​​coil 116 and the number of windings, and the permeability of coil 116 It is inversely proportional to the length of the winding.

[0254] In the resonant circuit section 12 housed in the stylus pen shown in Figures 4(a) and 4(b), Therefore, the design of the inductor section 14 is extremely important. In particular, in the design of the inductor section 14 As shown in Figure 6, inductance (L) and Q value are very important parameters. Here, the Q value is given by Q = 2dfL / R as a quantity that indicates the coil characteristics of the resonant circuit element. Here, L and R are the inductance and resistance of the coil, respectively, and f is the frequency. Therefore, the larger the Q value of the coil used, the sharper the resonance characteristics can be obtained.

[0255] In the stylus pen designs shown in Figures 4(a) and 4(b), L is intended to be used. It must have a self-resonance frequency that is sufficiently large for the frequency at which it resonates. Furthermore, it is preferable that the Q value has its maximum value at the frequency in which it is intended to be used. To achieve this, you need to consider the material of the ferrite core, the type of wire used in the coil, and the winding scheme. The following must be optimized: Also, a high output signal must be obtained while maintaining the diameter of a thin pen. A method is needed that can be done.

[0256] In the following embodiments, various ferrite core materials, coil wire types, and winding methods are used. This section describes the most optimized stylus pen design scheme among the various winding schemes. .

[0257] (1) Material of the ferrite core The ferrite core material used in this embodiment is manganese (Mn) and nickel (Ni). I used it.

[0258] (2) Wire type In this embodiment, enameled wire and litz wire were used as the types of wires for the coil. .

[0259] As shown in Figure 7, the enameled wire 100 has insulating enamel 102 on the surface of the copper wire 101. Electric wires made by covering them with a coating and heating them at high temperatures, used in electrical equipment, communication equipment, and electrical instruments, etc. Used for winding and wiring. In this embodiment, the overall thickness (T) is 0.2 mm, and the wire diameter is 0.2 mm. 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 Figure 8, Litz wire 200 is a thin insulated wire with a diameter of about 0.1 mm. Multiple strands of wire 100 (for example, enameled wire) are twisted together to form one strand, and then nylon or similar material is placed on top of it. This is a special insulated wire with an insulating coating 201. Litz wire 200 has a large surface area. This reduces the skin effect and is used in coils for high-frequency circuits, etc.

[0261] In this embodiment, the overall thickness (T) is 0.2 mm, the wire diameter (Φ) is 0.06 mm, and the insulation is... Litz wire with a casing 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. To obtain the value (i.e., a sufficient number of windings), a winding method having a multi-layer winding structure is used. The formula was used. Specifically, as shown in Figures 9(A) and (B), two types of multi-layered structures were used. A winding method was used.

[0263] The winding method in Figure 9(A) is the simplest winding method, and once the lower layer winding is finished, the upper layer... This is a sequential layer winding scheme in which the wire is wound. Method 9(A) is a method in which the winding of the layer directly above begins at the point 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 in Figure 9(B) is a method in which adjacent winding layers are wound alternately. (r winding scheme) where the windings of adjacent layers are wound in a zigzag pattern. This is the method. Hereafter, we will refer to this as the zigzag type winding method. Specifically, the first layer winding After winding the second layer of wire sequentially on the wire, the third layer of winding is wound between the first and second layers of winding. After winding the second layer of winding and then winding the fourth layer of winding on top of the second layer of winding, the fifth layer of winding is wound on top of the second layer of winding. This method involves winding between the fourth layer of windings. This zigzag type winding method is adjacent to This minimizes the voltage difference between the winding layers, and reduces winding self-capacitance (winding It has the advantage of being able to reduce parasitic capacitors. Winding self-capacitance, a type of self-capacitance, is the electric field energy (elec) stored within the winding. This is a parameter that indicates the tric field energy.

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

[0266] The measurement results showed almost no difference in the Q-value characteristics of each core material, and the measured Q-values ​​were also suitable for the product. It was a level far from sufficient to actually realize that vision.

[0267] Comparative Experiment 2 (Comparison of characteristic values ​​by winding type) The ferrite core is made of manganese (Mn), and the winding method is U-type. Inductor 1 and Inductor 2 were made using enameled wire and Litz wire, respectively. The Q-value was measured for ctor 2.

[0268] Figure 8 shows the frequency being changed via the KEYSIGHT TECHNOGIES E4980A precision LCR meter. This diagram shows the Q values ​​of inductor 1 and inductor 2, which were measured using the same method.

[0269] In Figure 10, a is inductor 1 (manganese core / enameled wire / U-type winding method) This waveform shows the change in the Q value with respect to frequency, where b is inductor 2 (manganese core / This waveform shows the change in the Q factor of a Litz wire (U-type winding method) with respect to frequency.

[0270] In inductor 2, which was made using Litz wire, the Q factor is around 400 kHz (frequency f1). The value shows almost the maximum value, and in inductor 1 made of enameled wire, the frequency around 150kHz The Q value shows approximately its maximum value at wavenumber (frequency f²).

[0271] Comparing Figures 10a and 10b, the maximum Q value of inductor 2 is greater than the maximum Q value of inductor 1. It can be seen that it is approximately 1.5 times higher. Therefore, to form a resonant circuit in the stylus pen... It can be seen that Litz wire is superior to enameled wire as a coil for an inductor.

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

[0273] Comparative Experiment 3 (Comparison of characteristic values ​​by winding method) With the ferrite core material set to manganese (Mn), the wire type is set to enameled wire and Three inductors were manufactured using Z-wire, with the winding method changed to U-type and zigzag-type. The Q value of inductor 5 was measured.

[0274] Figure 11 shows the frequency being changed via a KEYSIGHT TECHNOGIES E4980A precision LCR meter. This diagram shows the Q values ​​of inductors 3 to 5, which were measured after modification.

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

[0276] As can be seen from the c waveform in Figure 11, the inductor was made using the Litz wire / zigzag winding method. In setting 5, the Q value is approximately at its maximum value at a frequency of around 300 kHz (frequency f3). Enamel Inductor 4 made with wire / zigzag winding method and inductor 4 made with enameled wire / U-type winding method In inductor 3, the Q value is nearly at its maximum value at a frequency of around 150 kHz (frequency f2). vinegar.

[0277] Furthermore, comparing Figures 11a, b, and c, the maximum Q value of inductor 5 is found to be that of inductor 4. This is approximately 1.5 times higher than the maximum Q value, and more than twice as high as the maximum Q value of inductor 3. Therefore, the winding method of the inductor that forms the resonant circuit of the stylus pen is This shows that the zigzag winding method is superior to the U-type winding method.

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

[0279] Comparative Experiment 4 (Comparison of characteristic values ​​for different core materials) In this embodiment, manganese and nickel are used as the material for the ferrite core, and typically nickel The permeability of Kerne is known to be 200-300, while that of manganese is 3000-5000. It is.

[0280] Since the manganese used in this embodiment has a magnetic permeability about 15 times higher than nickel, the coil Assuming that the cross-sectional area and length are the same, to obtain the same inductance value, One advantage of using a nickel-plated winding is that it can reduce the number of windings by about four times compared to a nickel-plated winding. Therefore, from the perspective of the number of windings alone, using manganese is more effective than using nickel. This can be understood.

[0281] On the other hand, the inductor section 14 has a complex structure including a coil wound around the core. Parasitic capacitance is additionally formed. Due to this parasitic capacitance, Q Since the value decreases, there is a problem in that the amplitude of the resonant signal decreases.

[0282] The parasitic capacitance formed in the inductor section 14 is between the wound coils and the core. Although it can occur between the coil and the wire, as mentioned above, a zigzag type winding method is adopted. This reduces the parasitic capacitance between wound coils.

[0283] On the other hand, in this embodiment, in order to reduce the parasitic capacitance between the core and the coil, Core materials with a lower dielectric constant than Ngan were tested, and the test results showed that nickel cores were superior. We were able to confirm that it is the optimal material for the light core.

[0284] Important physical characteristics of manganese and nickel, which are mainly used as ferrite core elements. The property is permeability, which is the same as the inductance value as shown in <Equation 1>. This has a significant impact. However, in manganese and nickel as ferrite elements, Permittivity is a physical property of little interest, and in fact, nickel In some cases, the datasheet provided by the manufacturer may not even contain relevant information.

[0285] In this embodiment, to confirm the dielectric constants of manganese and nickel, KEYSIGHT TECHNOGIE Using S Company's E4980A Precision LCR meter, the dielectric constants of manganese and nickel were measured. The ity was measured, and the measurement results are shown in Table 1 below. [Table 1] Measurement 1 and Measurement 2 used the same KEYSIGHT TECHNOGIES E4980A precision LCR meter. The measurements were taken using the following method: Measurement 1 is the dielectric constant automatically calculated by the measurement software. As shown, Measurement 1 indicates that the dielectric constant of manganese is 2400, but the dielectric constant of nickel is measured It is clear that it will not happen.

[0286] Measurement 2 involves measuring the capacitance, area, and distance between ferrite cores to calculate the dielectric constant. According to the method described in Measurement 2, the dielectric constant of manganese is 8300, and the dielectric constant of nickel is 8300. The power factor was measured to be 2.

[0287] There is a significant difference in the dielectric constant results between Measurement 1 and Measurement 2, especially in the case of Measurement 2. It was confirmed that there were considerable errors due to factors such as passitance, area, and distance. However, measurement 1 and Measurement 2 showed that nickel has a dielectric constant at least 1 / 1000 smaller than manganese. This can be understood.

[0288] In comparative experiment 4, the ferrite core material was changed to nickel, and the wire type was changed to litz wire. With the winding method changed to U-type and zigzag-type, the inductor 6 and The Q value of inductor 7 was measured.

[0289] Figure 12 shows the frequency being changed via a KEYSIGHT TECHNOGIES E4980A precision LCR meter. This diagram shows the Q values ​​of inductors 6 and 7, which were measured after modification.

[0290] In Figure 12, a is inductor 6 (nickel core / litz wire / U-type winding method) This waveform shows the change in Q value with respect to frequency, where b is the inductor 7 (nickel core / ri This waveform shows the change in the Q value of a ZZ wire (zigzag type winding method) with respect to frequency.

[0291] As can be seen from waveform b in Figure 12, it was manufactured using a nickel core / litz wire / zigzag winding method. In the inductor 7, the Q value is approximately at its maximum value at a frequency of around 400 kHz (frequency f5). As shown, in inductor 6 manufactured using a nickel core / litz wire / U-type winding method, 200 The Q value is approximately at its maximum value at a frequency around kHz (frequency f6). Compare Figures 11a and 11b. As a result, the maximum Q value of inductor 7 was found to be approximately twice as high as the maximum Q value of inductor 6. I understand.

[0292] On the other hand, inductor 7 (nickel core / litz wire / zigzag tie) measured in comparative experiment 4 The maximum Q value of the (winding type) is nearly reached the target value (Qtarget) required for commercialization. It was.

[0293] In comparative experiments 1 through 4 described above, the material of the ferrite core and the type of wire used in the coil were different. By changing the combination of winding schemes and other factors, the Q value of the inductor is determined. The following tests were conducted, and the results showed that a nickel core, Litz wire, and zigzag winding method were used. When designing the inductor section of a passive resonant stylus pen, the highest possible Q factor is obtained. This was discovered. And the maximum Q value of the inductor made using this combination is It was found that the target value (Qtarget) for commercialization was reached.

[0294] On the other hand, in this embodiment, a nickel core is used as the ferrite core, and the wires of the core We experimented using Litz wire as one type of core, but in addition to nickel cores, we also used ferrite cores. The material used has a power of 1000 or less, and in addition to the Litz wire, one coil has two or more insulators. Similar results can be obtained when using a wire that covers the power line (strand). Probably.

[0295] The following describes the touch input device in the pen and touch input system according to embodiments of the present invention. Before going into detail about placement, let's look at the position of the stylus pen on the touchscreen. This explains why the output voltage (Vout) of the CVA (Capacitor Voltage Amplitude) changes. .

[0296] Figure 13 shows the CVA (Ca) based on the position of the stylus pen 10 on a conventional touchscreen. A schematic explanation to describe how the output voltage (Vout) of a passitor (voltage amplifier) ​​changes. This is a drawing.

[0297] Referring to Figure 13, the CVA changes depending on the position of the stylus pen 10 on the touchscreen. The reason why the output appears different is that both sides of the stylus pen 10 are centered on the sensing line. The result is a change in the impedance ratio.

[0298] Based on the long axis of conventional touchscreens, Metal Mesh touch sensors The resistance (R) is approximately 1.2kΩ, and the capacitance (C) is approximately 250pF.

[0299] Based on 10 distributed models, at a drive frequency of 300kHz, The impedance of a capacitor is approximately 200 times that of a resistor (120 ohms vs. .1 / (2π*300k*25pF) = 21k(ohm) is greater. Therefore, the capacitor is the main component. That is the cause.

[0300] Figure 14 shows the output voltage of the CVA (Vout1,Vo) depending on the position of the stylus pen 10 in Figure 13. To explain that ut2) is different via current sensing. Figure 15 is a diagram showing the output voltage of the CVA depending on the position of the stylus pen 10 in Figure 13. The difference between (Vout1, Vout2) is detected via voltage sensing. This is a diagram for explanatory purposes.

[0301] Referring to Figures 14 and 15, depending on the position of the stylus pen 10 on the sensing line, C The output voltage of VA is different. That is, the closer the stylus pen 10 is to the sensing circuit 50, the better. The output voltage of CVA is high, and the output voltage of CVA decreases as it moves further away from the sensing circuit section 50. It will get worse.

[0302] The following describes various embodiments of the present invention, including touch input devices, in detail with reference to the attached drawings. I will explain it to them.

[0303] Figure 16 shows a schematic configuration of the sensor unit 100 of a touch input device according to the first embodiment of the present invention. This is a drawing.

[0304] The touch input device according to the first embodiment of the present invention is a portrait-type touch input device. It may be a touch input device. Such a portrait-type touch input device has a wide width. It is even smaller, and the control unit (not shown) that controls the sensor unit 100 is located below the sensor unit 100. It may be placed in such a location. For example, such a touch input device may be in a shape that corresponds to a smartphone. .

[0305] The sensor unit 100 can detect the position of an object such as a finger located on the screen. Instead, it is possible to drive the stylus pen 10 shown in Figure 1a, which is positioned on the screen. The system senses the signal emitted from the stylus pen (stylus pen signal) and displays it on the screen. The position of the stylus pen can be detected.

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

[0307] The sensor unit 100 receives a number of first to fourth patterns 101, 102, 103, 104 It may be included.

[0308] The first pattern 101 has a shape that extends along an arbitrary first direction y. The first direction is It may be the long axis of the screen of the touch input device. The first pattern 101 is ATX(Active It may also be named TX). The first pattern 101 is an electrical channel along any first direction y. The path may have a predetermined shape.

[0309] The second pattern 102 has a shape that extends along the first direction y, and is the same as the first pattern 101. They are arranged adjacent to each other, and are positioned at a predetermined distance from the first pattern 101. Second pattern 1 Pattern 02 may also be named DTX (Dummy TX). Pattern 2, 102, is the same as Pattern 1. It may have a predetermined shape in which an electrical path is formed adjacent to 101 along the first direction y.

[0310] The third pattern 103 has a shape that extends 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 in the minor axis direction of the touch input device screen. It is acceptable. Pattern 3, 103, may also be named ARX (Active RX). Turn 103 has a predetermined shape in which an electrical path is formed along any second direction x. good.

[0311] The fourth pattern 104 has a shape that extends along the second direction x, and is the same as the third pattern 103. They are arranged adjacent to each other, and are positioned at a predetermined distance from the third pattern 103. Fourth pattern 1 04 can also be named DRX (dummy RX). The fourth pattern 104 is the third pattern 1 It may have a predetermined shape in which an electrical path is formed adjacent to 03 along the second direction x.

[0312] The third and fourth patterns 103 and 104 are arranged on the first and second patterns 101 and 102. They are placed and arranged at a predetermined distance from the first and second patterns 101 and 102. On the other hand, A sensor unit in which patterns 1 through 4 are arranged on the same layer is explained in detail in Figure 27.

[0313] Numerous first patterns 101 are arranged along the second direction x, and numerous second patterns 102 These are also arranged along the second direction x. Numerous third patterns 103 are arranged along the first direction y. Furthermore, numerous fourth patterns 104 are also arranged along the first direction y.

[0314] The first pattern 101 extends along the first direction y, and the third pattern 103 extends along the second direction x. As it extends, the first direction y is longer than the second direction x, so the number of the numerous first patterns 101 is large The number of items in the third pattern of numbers, 103, is less. Therefore, the number of items in the first pattern of numbers, 101, is less. The number of channels is less than the number of channels in the numerous third pattern, which is 103.

[0315] Here, the number of numerous first patterns 101 and the number of numerous third patterns 103 are... The input device's screen size may increase or decrease depending on the screen size.

[0316] The numerous second pattern 102 correspond one-to-one with the numerous first pattern 101, and the same individual It may consist of numbers. The other end (or second side end) of each of the many second patterns 102 is They are electrically connected to each other via a conductive pattern. Here, the conductive pattern is meta It may be Metal Mesh or Silver Trace.

[0317] One end (or first end) of the numerous second patterns 102 is electrically connected to a control unit (not shown). They may be connected in a specific way. Here, as shown in Figure 17, a number of second patterns 102 One end of two or more second patterns 102 may be electrically connected via a conductive pattern. With this configuration, a large number of channels in the second pattern 102 are connected to a large number of channels in the first pattern The number of channels can be reduced to half of 101. Here, among the many second patterns 102 Two or more second patterns 102 may be adjacent to each other.

[0318] On the other hand, as shown in Figure 18, each end of the numerous second patterns 102 individually They may be linked together in a single conductive pattern.

[0319] Referring again to Figure 16, a number of third patterns 103 are arranged along the first direction y. Therefore, the number of instances of the numerous third pattern 103 is greater than the number of instances of the numerous first pattern 101. Therefore, the number of channels in the numerous third pattern 103 is equal to the number of channels in the numerous first pattern 101. It's more than the number of channels.

[0320] The numerous fourth pattern 104 correspond one-to-one with the numerous third pattern 103, and the same individual It may consist of numbers. The other end (or second side end) of each of the many fourth patterns 104 is They are electrically connected via conductive patterns.

[0321] In the sensor unit 100 of the touch input device shown in Figure 16, a number of first particles Turn 101 and the numerous third patterns 103 are basically touches of finger-like objects. To sense this, a number of first patterns 101 are to which a touch drive signal is applied. It operates with a touch-driven electrode (TX electrode), and multiple third patterns 103 receive touch-sensing signals. It can operate using the transmitted touch-sensing electrode (RX electrode, or touch-receiving electrode). Of course, it can also work in the opposite way.

[0322] The sensor unit 100 of the touch input device shown in Figure 16 drives the stylus pen. ) in order to sense, a large number of first to fourth patterns 101,10 2, 103, and 104 can be used as various combinations. The various combinations are as follows: As shown in Table 2 below, "1" represents a large number of first patterns 101. "2" represents numerous second patterns 102, "3" represents numerous third patterns 103, "4" This refers to numerous fourth patterns 104. [Table 2] Referring to Table 2 above, in various combinations (No. 1 to No. 32), a large number of first Pattern 101 and numerous third patterns 103 sense the touch of an object like a finger. It is used for singling. Specifically, a number of first patterns 101 are used as touch drive electrodes. It operates in this way, and many of the third patterns 103 act as touch receiving electrodes. Of course, the opposite is also true. It is also possible.

[0323] At least one of the numerous first through fourth patterns 101, 102, 103, and 104. Alternatively, the two could function as stylus drive electrodes to power a stylus pen. This is possible. At least one of the first to fourth patterns 101, 102, 103, and 104. One or two patterns are used to form a current loop for driving the stylus pen. This is possible. For example, X-axis drive can be performed using a number of first patterns 101 and a number of second patterns 1 For any one of 02, the Y-axis drive is a number of third patterns 103 and a number of fourth patterns 10 It may be any one of the four. The stylus pen is driven by either the X-axis or the Y-axis. Either is possible, and both are possible.

[0324] At least one of the numerous first through fourth patterns 101, 102, 103, and 104. Alternatively, the second method involves sensing the signal emitted from the stylus pen. It can operate with a single electrode. For example, to sense the signal from a stylus pen. For this purpose, both X-axis sensing and Y-axis sensing are necessary, so a large number of first to fourth patterns Two patterns can be used from among 101, 102, 103, and 104. X-axis The sensing is performed using one of a number of first patterns 101 and a number of second patterns 102. Often, Y-axis sensing involves a large number of third patterns 103 and a large number of fourth patterns 104. Any one of them is fine.

[0325] In Table 2 above, "uplink signal magnitude" refers to the sta in Figure 1a. This refers to the magnitude of the drive signal used to power the IrasPen 10. The drive signal is applied to a number of first patterns 101 and a number of second patterns 102, respectively. When comparing the magnitude of the signals received by the tyrus pen, numerous second patterns 102 When a stylus pen drive signal is applied, the stylus pen is connected to a number of first patterns 101. The uplink signal is relatively stronger than the drive signal.

[0326] This is because, in many cases, the other end (or second side end) of the second pattern 102 is electrically connected. If the stylus pen drive signal is applied, then appropriately select one of two or more second patterns. If at least one current loop is formed, the other end of a number of first patterns 101 (Or, the second end) is not electrically connected to each other and a current loop cannot be formed. This is the case. When current flows through each first pattern 101, the RC of each first pattern 101 is Since it is being charged, one end (or first side end) of each first pattern 101 The current cannot flow as well as it moves from one end to the other (or the second end). Also, many The stylus pen drive signal applied via the first pattern 101 is capacitive The current is transmitted to a number of second patterns 102 through coupling, forming current loops. This is because signal attenuation occurs due to capacitive coupling.

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

[0328] In Table 2 above, "downlink signal magnitude" refers to the size of the downlink signal in Figure 1a. This refers to the magnitude of the stylus pen signal received from the stylus pen 10. The Raspen signal is transmitted via a number of first patterns 101 and a number of second patterns 102, respectively. When receiving and comparing the signal magnitudes, the stylus is found to be connected to numerous second patterns 102. When a pen signal is received, the stylus pen signal is received via a number of first patterns 101. The downlink signal is relatively stronger than when the signal is transmitted.

[0329] The reason is that many of the second patterns 102 have their other ends (second side ends) electrically connected. A current loop is formed, but many of the first patterns 101 are at the other end (first side end) They are not electrically connected to each other, in particular, current does not flow through capacitive coupling. From a number of second patterns 102 in which loops are formed, the stylus pen signal is sent to a number of first patterns This is because the signal is transmitted to the 101, and at this time, attenuation of the downlink signal occurs.

[0330] Similarly, when a stylus pen signal is received via a large number of fourth patterns 104, When the stylus pen signal is received via the third pattern of numbers 103, the downlink signal is better. The number is relatively larger.

[0331] In the above Table 2, "Stylus Additional Channel" refers to touch sensing Does this mean that in addition to the main channel, an additional channel must be configured for the stylus pen? It does so. Numerous second-party components are used for driving and sensing the stylus pen. When using turn 102 or / and multiple fourth patterns 104, an additional channel is required. This is required (indicated as "Yes" in Table 2). On the other hand, the driving and sensing of the stylus pen A number of first patterns 101 and / or third patterns 103 for touch sensing When used, no additional channels are required (indicated as "None" in Table 2).

This means that the other ends (second side ends) of a large number of fourth patterns 104 are electrically connected to each other.

[0347] Of the various combinations (No.1 to No.32) in Table 2 above, Nos.1, 5, 9, 25 ,29 is in the "Stylus Additional Channels" column where driving is "Yes", and sensitivity Sensing is "nothing".

That's fine.

[0350] Specifically, as shown in Table 2 above, Nos. 1 to 32, the control unit (not shown) is: The numerous first patterns 101 apply a touch drive signal, and the numerous third patterns 10 It may be used to receive touch-sensitive signals in step 3.

[0351] The control unit (not shown) is one of the numerous units, as shown in No. 1 to No. 32 in Table 2 above. Style in at least one of the first pattern 101 to the fourth pattern 104 A raspen drive signal is applied, and the numerous first patterns 101 to fourth patterns 104 This is for receiving the stylus pen detection signal in at least one of the patterns. good.

[0352] The control unit (not shown) is as shown in No. 13 to No. 32 in Table 2 above, and is one of the many... At least one of the first pattern 101 or the aforementioned number of third patterns 103 It may be used to apply a stylus pen drive signal.

[0353] The control unit (not shown) is No. 1-3, 5-7, 9-11, 13-15 in Table 2 above. , 17-19, 21-23, 25-27, 29-31, and so on, the numerous first patterns mentioned above. Stylus in 101 or at least one of the numerous third patterns 103 It may be used to receive pen detection signals.

[0356] The control unit (not shown) controls the numerous first patterns 101 to fourth patterns 104 Select at least one pattern as the pen drive electrode, and the selected pen drive It may be a device for applying a stylus pen drive signal to an electrode. Here, At least one of the numerous first patterns 101 to fourth patterns 104 mentioned above The reason for selecting the 'n' as the electrode for pen drive is the touchscreen of the touch input device 2 in Figure 1a. This can vary depending on the position of the stylus pen 10 on 20. The pattern selected when in (hover) state is when the stylus pen is in contact. The pattern selected may differ from the one selected when the system is in a certain state. For example, the control unit (shown in the figure) (zu) When the stylus pen is in the hover state, the first and second patterns 101,1 If one of 02 is selected as the pen drive electrode and the stylus pen is in contact: For this, one of the third and fourth patterns 103 and 104 is selected as the pen drive electrode. It is possible. Of course, the opposite is also possible.

The selection is made on the touchscreen 20 of the touch input device 2 in Figure 1a. This can vary depending on the position of the Spen 10. The pattern selected in this case is when the stylus pen is in contact. The selected pattern may differ. For example, the control unit (not shown) may use a stylus plate If the object is in a hover state, then one of the first and second patterns 101 and 102 is selected. Selected as an electrode for sensing, when the stylus pen is in contact, the third and One of patterns 103 or 104 can be selected as the electrode for pen sensing. Yes, it's possible. Of course, the opposite is also possible.

[0358] Figure 19 shows a schematic representation of the sensor section 100' of a touch input device according to a second embodiment of the present invention. This is a diagram of the configuration.

[0359] The touch input device according to the second embodiment of the present invention is of the landscape type. This is a touch input device. Such landscape-type touch input devices have a wide width. Furthermore, a control unit (not shown) that controls the sensor unit 100' is located below the sensor unit 100'. It may be placed in a suitable location. For example, such a touch input device may be compatible with the shape of a tablet PC. It is possible.

[0360] The configuration of the sensor unit 100' of the touch input device according to the second embodiment of the present invention is shown in Figure 16. The configuration of the sensor unit 100 of the touch input device according to the first embodiment is the same, and the direction is the same. It 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 comprises a number of first to Includes the 4th pattern 101, 102, 103, 104. 1st pattern 101 and 2nd putter The elements 102 are arranged adjacent to each other and have a shape that extends along one direction. Alternatively, the first part Turn 101 and the second pattern 102 are predetermined in which an electrical path is formed along one direction. It may have a shape. The third pattern 103 and the fourth pattern 104 are arranged adjacent to each other. , having a shape that extends along a direction different from the aforementioned one direction. Or, the third pattern 103 and The fourth pattern 104 has a predetermined shape in which an electrical path is formed along the other direction. It is acceptable. The other ends (second side ends) of the numerous second patterns 102 are electrically connected to each other, The other end (second side end) of the fourth pattern of numbers, 104, is also electrically connected to each other.

[0362] The sensor unit 100' of the touch input device according to the second embodiment shown in Figure 19 is landscape The screen size of a tablet PC is approximately 10 to 14 inches, and the above In the example of No. 1 in Table 2, the total channel of the sensor unit 100' is... If we roughly summarize the number of nnels and the number of drive trace channels (TX Trace Channels), This is as shown in Table 3 below. [Table 3] In Table 3 above, the number of channels in Stylus TX is 101 for a large number of first patterns. This is the value obtained by dividing the number by 2. This means that the number of the numerous second patterns (102) is equal to the number of numerous first patterns. Although the number is the same as that of line 101, as shown in Figure 20, there are many second patterns 1 One end (first side end) of 02 is electrically connected to two adjacent ends. This is due to the reduction in the number of channels by half.

[0363] In Table 3 above, the number of TX Trace channels is the number of Finger TX channels and Stylus This is the total number of TX channels. The number of TX trace channels is the number of touch inputs according to the second embodiment. This is a major factor in determining the thickness of the bezel in the width direction of the force device. Therefore, in the touch input device according to the second embodiment, the control unit (not shown) is the sensor unit 100' This is because it is placed below (or above). The fewer TX trace channels you reduce, the better. This allows for a reduction in the thickness of the bezel in the width direction of the touch input device.

[0364] On the other hand, the screen size of the touch input device shown in Figure 19 is the same as the screen size of a smartphone. Well, for example, there's no particular problem if it's 6.9 inches, but the touch input shown in Figure 19... The device's screen size is 11 inches or 12.9 inches, the same size as a tablet PC screen. When the size increases, the first to fourth patterns 101, 102, 10 of the sensor unit 100' Since the length of 3,104 also increases, the resistance and capacitance values ​​of the sensor section 100' increase. The increase in the resistance and capacitance values ​​corresponds to the first or third pattern of touch driving. A touch driving signal is applied to one of the patterns used as an electrode, and a stylus To narrow the operating frequency bandwidth of the stylus drive signal used to power the pen. Therefore, a problem may arise in which the operating frequency bandwidth required for the design cannot be obtained. To achieve this, it is necessary to consider reducing the resistance and capacitance values ​​of the sensor section 100'. It is possible, but there is a limit to how much this value can be reduced, and even if this value is reduced to the maximum extent, the aforementioned problems persist. However, it cannot be resolved.

[0365] Furthermore, the stylus receives input from the stylus pen and inputs it to the control unit of the touch input device. The pen signal also attenuates as the sensor unit 100' increases. In particular, the sensor unit 100' In patterns 101, 102, 103, and 104, the furthest from the control unit is The stylus pen sensing signal at the located portion is attenuated during the transmission process 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 Table 2 above. As in examples 9, 20, 23, 24, 27, 28, 31, and 32, there are many second patterns 10 2 can be used as a stylus pen sensing electrode to sense the stylus pen signal, or the above No.2,4,6,8,10,12,14,16,18,20,22,24, As in examples 26, 28, 30, and 32, numerous fourth patterns 104 are used as stylus pen signals. This can be solved by using it as a sensing electrode for a stylus pen. The example shows numerous second and fourth patterns 102 and 104, which are magnetically induced by a stylus pen. In order to receive the electromotive force directly via the second pattern 102 to the first pattern 101, the fourth Signal reduction via capacitive coupling from pattern 104 to third pattern 103 It shows no signs of decline.

[0367] As a specific example, the sensor unit 100' of the touch input device according to the second embodiment is a land It consists of screens approximately 10 to 14 inches in size, which is the screen size of a scape-type tablet PC. In the example of No. 3 in Table 2 above, the total channel of the sensor unit 100' is (Total When we organize the number of Channels and the number of Drive Trace Channels (TX Trace Channels), we get the following: As shown in Table 4. [Table 4] In Table 4 above, the number of channels in Stylus TX is the same as the number of 102 in the numerous second patterns. It is one. This means that the number of the numerous second patterns 102 is equal to the number of the numerous first patterns 101. The number is the same, and as shown in Figure 21, each end of the numerous second pattern 102 is This is due to each individual being linked to a single conductive pattern.

[0368] In Table 4 above, the number of TX Trace channels is the number of Finger TX channels and Stylus This is the total number of TX channels. The number of TX trace channels is the number of channels on the short axis bezel of the touch input device. The number of TX trace channels is a major factor in determining the thickness of the bezel. The more you reduce it, the thinner the bezel on the short axis of the touch input device can be.

[0369] The example in Table 4 above has the disadvantage of a slightly increased number of channels compared to Table 3 above, but , via numerous second patterns 102 rather than numerous first patterns 101, or In order to receive the pen sensing signal, the voltage value of the stylus sensing signal received by the control unit is Furthermore, it has the advantage of becoming larger. The applicant states that the voltage of the stylus sensing signal received by the control unit Experiments confirmed that there is an advantage in that the values ​​are approximately twice as large compared to those in Table 3.

[0370] Furthermore, since each of the numerous second patterns 102 consists of one channel, When the second pattern 102 is used as the stylus drive electrode (Stylus TX), <Table Compared to example 3>, the spacing between channels is halved, resulting in improved resolution for stylus driving. There are advantages.

[0371] As another specific example, the sensor unit 100' of the touch input device according to the second embodiment is The screen size of the 3DS-type tablet PCs is approximately 10 to 14 inches. Therefore, if this is embodied in example No. 8 in Table 2 above, the overall channel of the sensor unit 100' (T If we organize the number of total channels and the number of drive trace channels (TX Trace Channels), This is as shown in Table 5 below. [Table 5] In Table 5 above, the number of channels in Stylus TX is 104 in the numerous fourth patterns. It is the same as the number. This means that the number of the 4th pattern 104 is the same as the number of the 3rd pattern 10 The number is the same as 3, and as shown in Figure 22, one end of a large number of fourth patterns 104 This is due to each individual being linked to a single conductive pattern.

[0372] In the above Table 5, the number of TX Trace channels is the same as the number of Finger TX channels. Yes. The number of TX trace channels determines the thickness of the short-axis bezel of the touch input device. It is a major factor that affects this. The fewer TX trace channels you reduce, the less likely it is to succeed. The thickness of the bezel on the short axis of the input device can be reduced.

[0373] Table 5 above has the disadvantage of a slightly increased total number of channels compared to the example in Table 3 above. However, it receives pen sensing signals from the stylus pen via multiple fourth patterns 104. Therefore, there is an advantage in that the voltage value of the pen detection signal received by the control unit becomes even larger.

[0374] Furthermore, since each of the numerous fourth patterns 104 is composed of one channel, When pattern 4, 104 is used as the drive electrode (Stylus TX), see Table 3 above. As the spacing between channels is halved compared to the example, there is the advantage of improved driving resolution.

[0375] Furthermore, 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 bezel B in the width direction of the touch input device.

[0376] Figure 23 schematically shows yet another example of the sensor unit 100' shown in Figure 19. This is a diagram.

[0377] In Figure 23, the sensor unit 100'' has at least two first patterns 101'. This includes the first a pattern 101a and the first b pattern 101b, and each of the second patterns 1 02' includes at least two or more 2a pattern 102a and 2b pattern 102b. Numerous third and fourth patterns 103, 104 are identical to the sensor unit 100 in Figure 19.

[0378] Pattern 1a 101a and Pattern 1b 101b are extensions of Pattern 101'. They are arranged along the direction. Pattern 2a 102a and Pattern 2b 102b are the second pattern They are arranged along the extension direction of line 102'.

[0379] The other ends of the numerous 2a patterns 102a are electrically connected, and the numerous 2b patterns 10 The other end of 2b is electrically connected. Here, the other end of a large number of 2a patterns 102a and a large number The other ends of pattern 102b (2b) face each other.

[0380] One end of a large number of 2a patterns 102a is connected to two or more adjacent 2a patterns. They may be electrically connected. One end of a number of 2b patterns 102b may also be connected to two or more adjacent ends. A number of second b patterns may be electrically connected to one another. Here, a number of second a patterns One end of 102a and one end of the numerous second b patterns 102b are, as shown in Figure 9, Each of these may be individually electrically connected to a conductive pattern.

[0381] As a specific example, the sensor unit 100'' shown in Figure 23 is landscape type The screen sizes of tablet PCs are approximately 10 to 14 inches, and N is as shown in Table 2 above. In the case of the example in o.1, the total channel of the sensor unit 100'' is When the number and the number of drive trace channels (TX Trace Channels) are organized, it is as shown in Table 6 below. be. [Table 6] In the above Table 6, the number of channels for Stylus TX is a large number of second pattern 102' This is the value obtained by dividing the number by 2. This means that the number of the second pattern 102' is equal to the number of the first pattern 1. The number of second patterns 102' is the same as the number of patterns 101', and the numerous second patterns 102' are adjacent to each other. This is due to the two second patterns being 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 This is the total number of TX channels. The number of TX trace channels is the widthwise bezel of the touch input device. The number of TX trace channels is a major factor in determining the thickness of the bezel. The more you reduce it, the thinner the bezel on the short axis of the touch input device can be.

[0383] Table 6 above has the disadvantage of a slightly increased number of channels compared to the example in Table 3 above. Since the length of each first pattern 101' and second pattern 102' is reduced by half, the sensor unit 1 The touch drive applied to the touch drive electrode reduces the resistance and capacitance values ​​of 00''. The operating frequency bandwidth of the pen drive signal for driving the stylus pen is widened. There are advantages to doing so.

Here, the main pattern portion may have a diamond shape, but is not limited to this. Furthermore, it may have a diverse shape, different from the connecting pattern portion.

[0396] The third pattern 103A has an opening in which the fourth pattern 104A is arranged inside. The shape of the opening can correspond to the outer shape of the third pattern 103A. Third pattern n103A may have a structure that surrounds the fourth pattern 104A. The third pattern 103A is They are positioned at a predetermined distance from the fourth pattern 104A.

[0397] The fourth pattern 104A has a shape that extends along the second direction, and the third pattern 103A It is positioned adjacent to the third pattern 103A and at a predetermined distance from it. The fourth putter The N104A could also be named DRX (dummy RX).

[0400] The main pattern section of the fourth pattern 104A is the same as the main pattern of the third pattern 103A. The shape may correspond to the part, and the connecting pattern part of the fourth pattern 104A is the third pattern The shape may correspond to the connecting pattern section of part 103A.

[0401] The third and fourth patterns 103A and 104A are the same as the first and second patterns 101A and 102 Arranged on A, and positioned at a predetermined distance from the first and second patterns 101A and 102A. On the other hand, the sensor section in which the first to fourth patterns are arranged on the same layer is explained in detail in Figure 30. I will reveal it.

[0402] One end (first side end) of the numerous first patterns 101A is not shown in the drawing, but the control unit It is electrically connected to 300, and the other end (the second end) is electrically open. Thus, one end (first side end) is relatively close to the control unit 300, and the other end (second side end) The part is relatively far from the control unit 300.

[0403] Each of the numerous first patterns 101A has one end, which is not shown in the drawing, but is connected to the control unit 300. They may be electrically connected to each other via conductive patterns. A number of first patterns 101A The conductive pattern connecting the control unit 300 is the widthwise bezel B of the touch input device 500. They may be arranged inside.

After being electrically connected by a conductive pattern, the control unit 300 and the second conductive pattern They may be electrically connected via. The other end (second side end) of a number of second patterns 102A is They are electrically connected via a conductive pattern. One end (the first side end) is relative to the control unit 30. It is close to 0, and the other end (second side end) is relatively far from the control unit 300. ru.

[0405] The second conductive pattern connecting the numerous second patterns 102A and the control unit 300 is shown in Figure 2. As shown in 4, they may be arranged inside the widthwise bezel B of the touch input device 500. Here, the second conductive pattern connecting the numerous second patterns 102A and the control unit 300 is a conductive pattern (not shown) connecting a large number of first patterns 101A and the control unit 300. They may also be arranged inside the widthwise bezel B of the touch input device 500.

[0406] If the other ends of multiple second patterns 102A are electrically connected to each other, then each second pattern 1 02A Since another capacitance is added, the overall impedance will decrease. However This has the same effect as if the other end of a large number of second pattern 102A were connected to AC GND. It will become like that.

[0407] On the other hand, although not shown in the diagram, numerous second patterns 102A are electrically connected to each other. The other end may be grounded. Also, although not shown in the drawing, there are many second patterns 10 The other ends of 2A are not electrically connected to each other, and a predetermined cable is connected to the other end of each second pattern 102A. Pasita may be connected.

[0408] Numerous first patterns 101A and numerous second patterns 102A are placed on the same layer. i. Using metal mesh, a large number of first patterns 101A and a large number of second patterns Pattern 102A can be formed in the same layer.

[0409] One end (first side end) of each of the numerous third patterns 103A is electrically connected to the control unit 300. The other end (second side end) becomes electrically open. Here, one end (first side end) This end is relatively close to the control unit 300, while the other end (second side end) is relatively close to the control unit 30. It is far from 0.

Also, the other ends of multiple 4th pattern 104A are electrically connected to each other. Even if they are not directly connected, a predetermined capacitor may be connected to the other end of each fourth pattern 104A. stomach.

[0412] Numerous third patterns 103A and numerous fourth patterns 104A are placed on the same layer. i. Using metal mesh, numerous third patterns 103A and numerous fourth patterns Turn 104A can be formed in the same layer. Here, a number of third patterns 103 A and numerous 4th pattern 104A are numerous 1st pattern 101A and numerous 2nd patterns They may be placed on different layers from 102A. For example, multiple third patterns 103A and Numerous 4th pattern 104A are placed on the 1st floor, and numerous 1st pattern 101A and numerous The second pattern 102A may be placed on a second floor different from the first floor. On the other hand, the first to fourth The sensor section, in which the patterns are arranged on the same layer, is explained in detail in Figure 30.

[0413] The control unit 300 is electrically connected to the sensor unit 100A and controls the operation of the sensor unit 100A. It can be controlled. The connection between the control unit 300 and the sensor unit 100A is made of a large number of conductive patterns They may be electrically connected via [a certain method]. Here, the control unit (or controller) 300 is shown in Figure The touch controller 262 shown in 3 may be used, but is not limited to it. The controller 300 is a touch controller 262 and a display controller as shown in Figure 3. The roller 252 may be integrated, as shown in Figure 3, the touch controller 26 2 and controller 270 may be integrated, as shown in Figure 3. The roller 262, display controller 252, and controller 270 are integrated. It may be a separate device included in the sensor unit 100. It may also be a controller. Therefore, the controller 300 in the present invention is shown in Figure 3. This is not limited to the touch controller 262 or controller 270, Not only the sensor unit 100, but also those that can control the sensor units of subsequent embodiments are "Co It could be named "Tontorola".

[0414] The control unit 300 may include a number of drive circuit units 310 and a number of sensing circuit units 330. Here, although not shown in separate drawings, there are numerous drive circuit sections 310 and numerous sensing circuit sections 330 At least one of these may not be included in the control unit 300 and may be located outside the control unit 300. stomach.

[0415] The numerous drive circuit units 310 are for sensing the touch position of an object such as a finger. A drive circuit section that provides touch drive signals to a number of first patterns 101A, and a stylus section It may include a drive circuit section that provides a pen drive signal for driving the pen.

[0416] Multiple sensing circuit units 330 receive sensing signals via multiple third patterns 103A. A sensing circuit for detecting the touch position of an object such as a finger, and a sensor for a stylus pen. It may include a sensing circuit section for a single. Here, some of the sensing circuit sections among a number of sensing circuits may be The circuit section performs both touch position sensing and stylus pen sensing. It is possible.

[0417] The control unit 300 controls the sensor unit 100A in touch-driven / sensing mode and antenna-driven mode. It is controlled to operate in either mode or stylus pen sensing mode. It can be controlled. The control unit 300 has a number of drive / sensing circuit units 310 depending on the mode. ,330 can be electrically selectively connected to the sensor unit 100A and controlled. Therefore, the control unit 300 controls a number of drive / sensing circuit units 310 in accordance with the commands of the control unit 300. The circuit may include a number of switches that electrically connect the 330 and the sensor unit 100A.

[0418] The operating modes of the touch input device 500 shown in Figure 24 will be explained in detail. Since 24 is shown as example No. 1 in Table 2 above, we will explain based on this. .

[0419] In touch-driven / sensing mode, the control unit 300 detects touch from an object such as a finger. For position sensing, a number of drive circuit units 310 are connected to a number of first parts of the sensor unit 100A. It can be electrically connected to turn 101A. The control unit 300 controls a number of switches Controlling the conductive patterns connected to a large number of first patterns 101A to a large number of drive circuit sections It can be electrically connected to the 310.

[0420] Furthermore, the control unit 300 comprises a number of sensing circuit units 330 for sensing the touch position. Multiple third patterns 103A of the sensor section 100A can be electrically connected. Section 300 controls a number of switches and is connected to a number of third patterns 103A. The patterns can be electrically connected to multiple sensing circuit units 330.

[0421] In this touch-driven / sensing mode, the control unit 300 controls a number of first patterns The 101A simultaneously sends a drive signal (or touch drive signal) for touch sensing. The signals are applied sequentially, and the sensing signals (or touch sensing signals) received from multiple third patterns 103A are then applied sequentially. It receives (number). A number of control units 300 are electrically connected to a number of third patterns 103A. The sensing circuit section uses information about the capacitance change amount included in the input sensing signal to determine a predetermined electrical signal. It can output as a voltage value. The control unit 300 processes the output voltage value to determine the touch position. It can be detected.

[0422] On the other hand, in touch-driven / sensing mode, a large number of first patterns 101A and a large number of second patterns Capacitive coupling occurs between turn 102A and turn 102A. To prevent this, the control unit 300 has multiple drive circuit units 310 for multiple second patterns 102A They can be electrically connected. At this time, the control unit 300 has a number of first patterns 101 The same drive signal applied to A is also applied to numerous second patterns 102A. It can be controlled in this way. Alternatively, the control unit 300 can drive a number of first patterns 101A When a signal is applied, a predetermined reference potential is set for the numerous second patterns 102A. It can also be controlled to ensure that it is applied.

[0423] Antenna drive mode (or stylus drive mode, or stylus uplink mode) (D) At that time, the control unit 300 controls a number of drive circuit units 310 for driving the antenna. It can be electrically connected to a large number of 0A second patterns 102A. The control unit 300 ...controlling a large number of switches to connect a large number of conductive patterns to a large number of second patterns 102A It can be electrically connected to numerous drive circuit units 310.

[0424] The control unit 300 outputs from each drive circuit section 310 connected to a number of second patterns 102A The drive signal (or pen drive signal) being driven can be controlled. For example, control unit 30 0 is one of the many drive circuit sections 310 connected to many second patterns 102A, the first drive The drive circuit section is controlled to output a pulse signal of a predetermined frequency, and the second drive circuit section... From there, it is controlled so that no pulse signals are output, and from the third drive circuit section, An inverted pulse signal, which has the opposite phase to the pulse signal output from the first drive circuit section, is output. It can be controlled in this way. In this case, the second part is electrically connected to the first drive circuit. A current loop is formed between the turn and the second pattern, which is electrically connected to the third drive circuit section. The current loop formed generates a magnetic field, which brings the sensor unit 100A closer. The stylus pen may be activated.

[0425] The control unit 300 consists of numerous drive circuit units electrically connected to numerous second patterns 102A. Of the 310, any two drive circuit sections will output mutually opposing drive signals. It can be controlled. Therefore, the control unit 300 can vary the size and position of the current loop. The settings can be changed. For example, the control unit 300 is located close to the sensor unit 100A. If the position of the stylus pen is detected, two second patterns are generated around the stylus pen's position. Controlled so that mutually opposing pulse signals are output from the drive circuit section electrically connected to it. It is possible to do this, and if the position of the stylus pen cannot be detected, a number of second patterns 1 The drive circuit section is electrically connected to the two second patterns located on the outermost edges of both sides of 02A. It is also possible to control the output so that mutually opposing pulse signals are output.

[0426] Figure 25 shows the control unit 300 in Figure 24 driving a stylus pen onto a number of second patterns 102A. This is a diagram illustrating how to apply the pen drive signal to make it move. For reference, In Figure 25, one of the second patterns 102A shown in Figure 24 is simply represented by a single line Ch. Each line (Ch) becomes a single channel.

[0427] As shown in Figure 25, two adjacent second patterns are electrically connected. It is configured as two channels. When configured in this way, two electrically connected channels In both patterns, the same signal is applied simultaneously. Figure 25 shows 84 second patterns, paired together. These are linked together to form 42 channels, Ch0, Ch1, ..., Ch41.

[0428] For example, among the 42 channels Ch0, Ch1, ..., Ch41 of the stylus pen 50 When located between the second channel Ch2 and the third channel Ch3, the control unit 300 is stylish Pen drive is performed on one or more channels located on the second channel Ch2 side, with the Raspen 50 as the reference. The signal is controlled to be output, and the stylus pen 50 is used as the reference for the third channel Ch3 side. One or more channels located at the specified position output a pen drive signal having an inverted phase of the pen drive signal. It can be controlled to behave in this way.

[0429] When in stylus sensing mode (or stylus downlink mode), the control unit 30 0 is a plurality of sensing circuit sections 330 for stylus sensing, which are numerous of the sensor section 100A. It can be electrically connected to the first pattern 101A and numerous third patterns 103A. 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 connected to a number of sensing circuit sections 330 and electrically It can be linked to it.

[0430] The touch input device 500 according to an embodiment of the present invention is configured such that the sensor unit 100A is In stylus sensing mode, the position of the stylus pen on the sensor unit 100A determines the number of It has the advantage that the output voltage value of the sensing circuit section 330 is hardly changed. The principle will be explained with reference to Figures 26(a) through (f).

[0431] Figures 26(a) through (f) show the touch input device in Figure 24 with a stylus sensing motion This is a diagram to provide a general explanation of the operating principle of the device.

[0432] Figure 26(a) shows one of the first patterns 101A shown in Figure 24, and an electric current added to it. This is a schematic circuit diagram that models the sensing circuit section 330 of the electrically connected control unit 300. Figure 26(b) shows a second arrangement located inside one of the first patterns 101A. This is a schematic model of pattern 102A. Figure 26(c) is a schematic model of Figure 26. (a) is a voltage distribution graph in the circuit diagram, and Figure 26(d) is the same as Figure 26(b). This is a voltage distribution graph in a road diagram.

[0433] Referring to Figures 26(a) and (c), the sensing circuit section 330 is located on the first pattern 101A. If the stylus pen approaches any point A as far away as possible, then the stylus will be able to reach point A. The voltage (Vemf, hereafter referred to as "induced voltage") induced by the signal emitted from the tyrus pen is... This occurs. If an induced voltage (Vemf) is generated at point A, then when 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 almost entirely applied to the left of point A, and point A On the right side, a voltage close to 0 (V) is applied, and almost no current flows. Moreover, A The voltage to the right of the point, which is close to 0 (V), is gradually reduced by the equivalent resistance of the first pattern 101A. The voltage drops even further, and almost no voltage is applied to the input terminal of the sensing circuit.

[0434] Referring to Figures 26(b) and (d), if an induced voltage (Vemf) is generated at point A, On the left side of point A, the other ends of each second pattern 102A are electrically connected to each other, so point A As the equivalent capacitance increases when viewed from the left, the equivalent impedance approaches almost zero. Therefore, the left side of point A is affected by 0(V), and the right side of point A is affected by the second pattern 102. Since one end of A is open, there is no voltage drop across the equivalent resistance, and Vemf remains unchanged. It will cost.

[0435] Comparing Figure 26(c) and (d), we see that the first pattern 101A and the second pattern 10 It can be confirmed that a potential difference of approximately Vemf exists between point 2A and the other point at any position. The potential difference of Vemf between the first pattern 101A and the second pattern 102A is the first pattern Capacitive coupling between pattern 101A and pattern 102A This causes oupling. Capacitive coupling is shown in Figure 26(e). As shown, current flows from the second pattern 102A to the first pattern 101A. The further the stylus pen is from the sensing circuit section 330 of the control unit 300, the greater the first phase. The current generated by turn 101A itself gradually decreases, but the second pattern 102A... As current flows into the first pattern 101A, the control unit 300 The current output to the sensing circuit section 330 will be almost the same as the position of the pen. The control unit 300 then communicates via the sensing circuit unit 330, which is electrically connected to the first pattern 101A. This allows the device to sense the position of the stylus pen.

[0436] And, as can be seen through Figures 26(a) to (e), point A is on the left or right side Even when moved, the potential difference between the first pattern 101A and the second pattern 102A remains constant as Vemf. It can be seen that it is fixed. Therefore, the position of the stylus pen on the sensor unit 100A is detected. Regardless of whether it is close to or far from the sensing circuit unit, the control unit 300 receives output from the sensing circuit unit 330. The stylus pen can be sensed from a certain signal.

[0437] On the other hand, in the explanation for (e) in Figure 26, there is an inflow from the second pattern 102A to the first pattern 101A. The current was explained as being due to capacitive coupling, but this is not limited to that. There is no such thing. For example, the current flowing from the second pattern 102A to the first pattern 101A is, This is also possible through magnetic coupling (magnetic coupling).

[0438] The principles of Figure 26 (a) through (e) described above apply to any one of the third directions in the second direction. This also applies directly to Turn 103 and the fourth pattern 104. This can also be applied directly to a touch input device according to one embodiment.

[0439] Figure 26(f) is a model of the second pattern 102A shown in Figure 26(b). This 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. In other words, the voltage distribution graph in Figure 26(f) shows that one end of the second pattern 102A is controlled This is an example of the case where the sensing circuit section 330 of section 300 is connected. Figure 26(f) and Comparing (d), in Figure 26 (f), the equivalent resistance increases as you move to the right of point A. A pressure drop occurs. Therefore, in the case of (f) in Figure 26, the following occurs as in Figure 26(e): The potential difference between pattern 1 and pattern 2 could not be maintained by Vemf, and from pattern 2 The current cannot be transferred to the first pattern. Therefore, the position of the pen is from the control unit 300. The further away you are, the less current will be output from the first pattern. In single mode, one end of the second pattern 102A is left open to allow floating. This is preferable.

[0440] The screen size of the touch input device shown in Figure 26 is the same as the screen size of a smartphone, for example. For example, there is no particular problem if it is 6.9 inches, but the touch input device shown in Figure 26 The screen size is approximately 10 inches to 14 inches, which is the size of a tablet PC screen. If the current increases, the current of the sensor unit 100A will also increase, so the resistance of the sensor unit 100A and the current will increase. The passivity value increases. The increase in resistance and capacitance values ​​is applied to the touch drive electrode. Operating frequency band of the touch drive signal and the pen drive signal for driving the stylus pen. The bandwidth is much narrower than when it's a smartphone (when it's 6.9 inches). This results in a problem where the operating frequency bandwidth required for the design cannot be obtained.

[0441] Furthermore, the pen detection signal received from the stylus pen has also increased in size in the sensor unit 100A. It attenuates by minutes. In particular, the part of the sensor unit 100A that is located furthest from the control unit 300. The pen sensing signal in the first minute is attenuated during the transmission process to the control unit 300, and the portion required for the design is reduced. There is a problem in that the voltage value cannot be output.

[0442] The following describes a touch input device that can solve the problems mentioned above.

[0443] Figure 27 is a diagram illustrating the touch input device shown in Figure 21.

[0444] Referring to Figure 27, the touch input device 500'' consists of a sensor unit 100A'' and the sensor unit. The control unit 300 may include a control unit 300 for controlling the sensor unit 100A''.

[0445] The sensor unit 100A'' has multiple first to fourth patterns 101A, 102A'', 1 Includes 03A, 104A. Here, numerous first, third, and fourth patterns 101A, 10 3A, 104A are numerous first, third, and fourth patterns 101A, shown in Figure 24. Since it is identical to 103A and 104A, the explanation for them will be omitted.

[0446] The following describes numerous second patterns 102A'', but the numerous second patterns in Figure 12 For convenience, explanations for parts identical to Pattern 102A will be omitted.

[0447] Each of the numerous second patterns 102A'' has one end (first side end) which is a conductive pattern. Therefore, it may be electrically connected to the control unit 300. This part is one of the many second patterns shown in Figure 24. It is different from 102A.

[0448] The other end (second side end) of the numerous second patterns 102A'' is electrically charged via the conductive pattern. They are electrically connected. One end is relatively close to the control unit 300, and the other end is relatively close to the control unit. It is far from the 300th floor of the Imperial Household Agency.

[0449] The operating modes of the touch input device 500'' shown in Figure 27 will be explained in detail.

[0450] In touch-driven / sensing mode, the control unit 300 detects touch from an object such as a finger. For position sensing, numerous drive circuit units 310 are connected to numerous first sensor units 100A'' It can be electrically connected to pattern 101A. The control unit 300 has a number of switches Controlling the conductive patterns connected to a large number of first patterns 101A, and driving the large number of drive circuit sections It can be electrically connected to the 310.

[0451] Furthermore, the control unit 300 comprises a number of sensing circuit units 330 for sensing the touch position. Multiple third patterns 103A of the sensor section 100A'' can be electrically connected. The control unit 300 controls a number of switches connected to a number of third patterns 103A The conductive pattern can be electrically connected to multiple sensing circuit sections 330.

[0452] In this touch-driven / sensing mode, the control unit 300 controls a number of first patterns The 101A simultaneously sends a drive signal (or touch drive signal) for touch sensing. The signals are applied sequentially, and the sensing signals (or touch sensing signals) received from multiple third patterns 103A are then applied sequentially. It receives (number). A number of control units 300 are electrically connected to a number of third patterns 103A. The sensing circuit section uses information about the capacitance change amount included in the input sensing signal to determine a predetermined electrical signal. It can output as a voltage value. The control unit 300 processes the output voltage value to determine the touch position. It can be detected.

[0453] Antenna drive mode (or stylus drive mode, or stylus uplink mode) (D) At that time, the control unit 300 controls a number of drive circuit units 310 for driving the antenna. It can be electrically connected to a large number of second patterns 102A'' of 0A''. 300 controls a number of switches and is connected to a number of second patterns 102A'' The behavioral patterns can be electrically connected to numerous drive circuit sections 310.

[0454] The control unit 300 controls each drive circuit section 310 connected to a number of second patterns 102A'' The control unit 300 can control the drive signal (or pen drive signal) output from it. Among the numerous drive circuit sections 310 electrically connected to numerous second patterns 102A'' It is possible to control any two drive circuit sections so that they output mutually opposing pulse signals. Yes, it is possible. Therefore, the control unit 300 can change and set the size and position of the current loop in various ways. It is possible.

[0455] When in stylus sensing mode (or stylus downlink mode), the control unit 30 0 is a sensor unit 100A'' with multiple sensing circuit units 330 for stylus sensing. Electrically connect to multiple second patterns 101A'' and multiple third patterns 103A. This is possible. This part is the stylus sensing motion of the touch input device shown in Figure 12. It is different from Do.

[0456] 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 connected to a number of sensing circuit sections 330 and electrically It can be linked to it.

[0457] The touch input device 500'' shown in Figure 27 is compared to the touch input device shown in Figure 24. In contrast, the sensor unit 100A'' has multiple second patterns 102A'' connected to the control unit 300. There are differences in the connecting configuration. That is, the numerous second patterns 102A in Figure 24 are mutually exclusive. After two adjacent second patterns are electrically connected by the first conductive pattern, It is connected to the 300 via the second conductive pattern, but there are many second patterns 1 in Figure 27 Each of the 02A'' is connected to the control unit 300 by a conductive pattern. Due to its configuration features, the touch input device 500'' shown in Figure 27 is the same as the touch input device in Figure 24. Although it has the disadvantage of having more channels than the input device 500, it drives the stylus pen. In the antenna drive mode, the pen drive signal is transmitted only to the specific area where the stylus pen is positioned. Since a voltage can be applied, it has the advantage of reducing power consumption.

[0458] Furthermore, the touch input device 500 shown in Figure 24 is used in stylus sensing mode. The pattern that senses the signal emitted from the tyrus pen has a large number of first patterns along the long axis L. The first pattern is 101A, and there are many third patterns 103A in the short axis direction S, while in Figure 27... The indicated touch input device 500'' is a stylus pen in stylus sensing mode. The pattern that senses the signal emitted from is a second pattern 102A with many occurrences along the long axis L. '' and there are numerous third patterns 103A in the short axis direction S.

[0459] In the touch input device 500'' shown in Figure 27, when in stylus sensing mode... A pattern in the long axis L that senses the signal emitted from the stylus pen is generated by a number of first patterns If we use a number of second patterns 102A'' that are not turn 101A, then the tap shown in Figure 24 Compared to the input device 500, between the first pattern 101A and the second pattern 102A'' This reduces the coupling capacitance, which improves the sensing of the touch position. This improves the operating frequency bandwidth of the touch drive signal and touch sensing signal. This allows for an improvement in the operating frequency bandwidth of the pen drive signal for stylus pen operation. It is possible.

[0460] Furthermore, in stylus sensing mode, the pen sensing signal from the stylus pen is processed by multiple parties. The control unit 300 receives the received pen sensing signal via the two patterns 102A''. It has the advantage of having a relatively high voltage value. In particular, in the long axis direction L, the control unit 300 is most The voltage value of the pen detection signal received at a distant location is relatively larger than in the case shown in Figure 24. Therefore, there is the advantage of improved sensing sensitivity. This is the first pattern 101A and the second pattern Considering capacitive coupling with Turn 102A This is because it is not necessary. Specifically, in the case of Figure 24, as described above in Figure 26(e), Capacitive coupling between the first pattern 101A and the second pattern 102A So, current flows from the second pattern 102A to the first pattern 101A, therefore the first pattern There is attenuation of the pen sensing signal input to the control unit 300 via 101A. However, Figure 27 touch input devices 500'' are not the first pattern 101A but the second pattern 102 Because it is input directly to the control unit 300 via A'' without capacitive coupling, Capacitive coupling prevents attenuation of the pen detection signal.

[0461] Furthermore, since each of the numerous second patterns 102A'' consists of one channel, When a large number of second patterns 102A'' are used as driving electrodes (Stylus TX), Figure Because the spacing between channels is halved compared to 24 touch input devices, the drive resolution is improved. There is a dot.

[0462] Figure 28 is a diagram illustrating the touch input device shown in Figure 22.

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

[0464] The sensor unit 100A''' has multiple first to fourth patterns 101A, 102A''' Includes 103A,104A'. Here, numerous first and third patterns 101A,103 Since A is identical to the numerous first and third patterns 101A, 103A shown in Figure 24, I will omit the explanation for this.

The control unit 300 controls a number of switches connected to a number of third patterns 103A The conductive pattern can be electrically connected to a large number of sensing circuit sections 330.

[0471] In this touch-driven / sensing mode, the control unit 300 controls a number of first patterns The 101A simultaneously sends a drive signal (or touch drive signal) for touch sensing. The signals are applied sequentially, and the sensing signals (or touch sensing signals) received from multiple third patterns 103A are then applied sequentially. It receives (number). A number of control units 300 are electrically connected to a number of third patterns 103A. The sensing circuit section uses information about the capacitance change amount included in the input sensing signal to determine a predetermined electrical signal. It can output as a voltage value. The control unit 300 processes the output voltage value to determine the touch position. It can be detected.

[0472] Antenna drive mode (or stylus drive mode, or stylus uplink mode) (D) At that time, the control unit 300 controls a number of drive circuit units 310 for driving the antenna. Multiple 0A'' fourth patterns 104A' can be electrically connected. 300 is a conductive circuit that controls multiple switches and connects to multiple 4th patterns 104A'. The patterns can be electrically connected to multiple drive circuit sections 310.

[0473] The control unit 300 is connected to each drive circuit section 310 which is connected to a number of fourth patterns 104A'. The output drive signal (or pen drive signal) can be controlled. The control unit 300 is: Any of the numerous drive circuit sections 310 electrically connected to the numerous fourth patterns 104A' It is possible to control the two drive circuit sections so that mutually opposing pulse signals are output. Therefore, the control unit 300 can change and set the size and position of the current loop in various ways. It is possible.

[0474] When in stylus sensing mode (or stylus downlink mode), the control unit 30 0 is a sensor unit 100A''' with multiple sensing circuit units 330 for stylus sensing. To be electrically connected to a large number of first patterns 101A and a large number of fourth patterns 104A' This is possible. This part differs from the stylus sensing mode of the touch input device in Figure 24. Yes.

[0475] The control unit 300 controls a number of switches to generate a number of first patterns 101A and a number of other patterns The conductive patterns connected in 4 patterns 104A' are electrically connected to numerous sensing circuit sections 330. They can be connected together.

[0476] The touch input device 500'' shown in Figure 28 is the same as the touch input device shown in Figure 24. In comparison, many of the second patterns 102A''' of the sensor section 100A''' are electrically flow It is not used as a coating, and is a stylus pen via numerous 4th pattern 104A' There is a difference in that it drives the [something]. Due to these configuration characteristics, the [something] shown in Figure 28 The touch input device 500''' has an increased number of channels compared to the touch input device 500 in Figure 24. Although it has disadvantages, since many second pattern 102A are not used, many second pattern 1 There is no conductive pattern connected to one end of 02A. Therefore, the left / right bezel B This has the advantage of significantly reducing the thickness compared to Figure 24.

[0477] The touch input device shown in Figure 28 has a total channel compared to the touch input device in Figure 24. Although it has the disadvantage of slightly increasing the number, stylus pens can be used via numerous 4th pattern 104A'. To directly receive the pen sensing signal from the control unit 300, the voltage of the pen sensing signal received is There is an advantage in that the value becomes larger. The control unit 300 of the touch input device in Figure 24 receives the It has the advantage of being about twice as large as the voltage value of the sensor signal.

[0478] Furthermore, since each of the numerous fourth patterns 104A' is composed of one channel, Figure 24 shows the case where the fourth number pattern 104A' is used as the driving electrode (Stylus TX). Because the spacing between channels is halved compared to touch input devices, there is an advantage in that the driving resolution is improved. be.

[0479] Furthermore, the number of TX trace channels is 1 / 4 to 1 / 2 of that of the touch input device shown in Figure 24. This allows us to reduce the number to 3, which has the advantage of reducing the thickness of bezel B.
