Description

[Technical field]

[0001] The present disclosure relates to pens and controllers, and more particularly to controllers for controlling touch input systems and devices that include a sensor portion and can interact with a stylus pen. [Background technology]

[0002] A variety of touch input devices, such as mobile phones, smart phones, laptop computers, digital broadcasting terminals, personal digital assistants (PDAs), portable multimedia players (PMPs), navigation systems, slate PCs, tablet PCs, Ultrabooks, and wearable devices, are equipped with touch sensors.

[0003] In such touch input devices, a touch sensor may be located on a display panel that displays images or may be located as a part of the touch input device, and a user may interact with the electronic device by touching the touch sensor, thereby providing the user with an intuitive user interface.

[0004] A user can use a stylus pen for precise touch input. Stylus pens can be classified into active stylus pens and passive stylus pens depending on whether they have a battery and electronic components inside.

[0005] Active stylus pens have the advantage of being superior in basic performance compared to passive stylus pens and providing additional functions (pressure, hovering, buttons), but they have the disadvantage that the pen itself is expensive and requires a power source to be charged by a battery, so there are only a few high-end users.

[0006] Passive stylus pens have the advantages of being cheaper and not requiring batteries compared to active stylus pens, but have the disadvantage of being more difficult to recognize precise touches than active stylus pens. Recently, however, in order to realize passive stylus pens that can recognize precise touches, the inductive resonance method EMR (Electro Magnetic Resonance) method and the capacitive resonance method have been proposed.

[0007] The EMR method has the advantage of the quality of writing / drawing, which is the core function of a stylus pen, but it has the disadvantage of being thick and expensive because a separate EMR sensor panel and EMR driving IC must be added in addition to the capacitance touch panel.

[0008] The capacitive resonance method uses a general capacitance touch sensor and touch controller IC, which not only eliminates additional costs but also improves IC performance to support pen touch.

[0009] In the EMR or capacitive resonance method, the amplitude of the resonance signal must be large in order for the touch sensor to more accurately identify the touch by the stylus pen, and therefore the frequency of the drive signal transmitted to the stylus pen must be almost the same as the resonance frequency of the resonance circuit built into the stylus pen. However, in the conventional EMR or capacitive resonance method, even if the resonance frequency and the frequency of the drive signal match, there is a problem that the attenuation of the signal transmission is very large, making it difficult to transmit the signal. As a result, despite many attempts by many touch controller IC vendors, there is still no manufacturer that has succeeded in mass production because a sufficient output signal cannot be obtained.

[0010] Therefore, in order to manufacture an EMR type or capacitive resonant stylus pen capable of generating a maximum output signal, how the internal resonant circuit and the structure of the pen are designed is a very important factor. Summary of the Invention [Problem to be solved by the invention]

[0011] The present embodiment is directed to providing a controller for controlling a pen, including a stylus pen, capable of producing a sufficient output signal, and a touch input system and device capable of interacting with the pen.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0134] Hereinafter, various embodiments of the present document will be described with reference to the attached drawings. However, this is not intended to limit the technology described in this document to a specific embodiment, but should be understood to include various modifications, equivalents, and / or alternatives of the embodiments of this document. In connection with the description of the drawings, similar reference numerals may be used for similar components.

[0135] In addition, the size and thickness of each component shown in the drawings are arbitrarily shown for convenience of explanation, and the present invention is not necessarily limited to those shown. In the drawings, thicknesses are enlarged to clearly show various layers and regions. In the drawings, thicknesses of some layers and regions are exaggerated for convenience of explanation.

[0136] In addition, when a part such as a layer, film, region, or plate is said to be "on" a different part, this includes not only the case where it is "directly on" the different part, but also the case where there is another different part in between. Conversely, when a part is said to be "directly on" a different part, it means that there is no different part in between. In addition, being "on" a reference part means being located above or below the reference part, and does not necessarily mean being located "on" the side opposite to gravity.

[0137] In this document, the terms "have," "may have," "include," or "may include" indicate the presence of a given feature (e.g., a value, a function, an operation, or a component such as a part) and do not exclude the presence of additional features.

[0138] In this document, phrases such as "A or B," "at least one of A and / or B," or "one or more of A and / or B" may include all possible combinations of the items listed together. For example, "A or B," "at least one of A and B," or "at least one of A or B" can refer to all of the following: (1) at least one A, (2) at least one B, or (3) at least one A and at least one B.

[0139] The terms "first," "second," "first," or "second" used herein may modify various components regardless of order and / or importance, and are used only to distinguish one component from another, and do not limit the components. For example, a first user device and a second user device may indicate different user devices regardless of order or importance. For example, a first component may be named a second component, and similarly, a second component may be named instead of a first component, without departing from the scope of the rights described herein.

[0140] When a component (e.g., a first component) is referred to as being "operatively or communicatively coupled with / to" or "connected to" another component (e.g., a second component), it should be understood that a component may be directly coupled to a different component or may be coupled through another component (e.g., a third component). Conversely, when a component (e.g., a first component) is referred to as being "directly coupled with" or "directly connected to" another component (e.g., a second component), it should be understood that there is no other component (e.g., a third component) between the component and the different component.

[0141] As used herein, the phrase "configured to" may be used variably, e.g., "suitable for," "having the capacity to," "designed to," "adapted to," "made to," or "capable of," depending on the context. The term "configured to" does not necessarily mean only something that is "specifically designed to" in terms of hardware. Instead, in some contexts, the phrase "a device configured to" may mean that the device is "capable of" working with different devices or components. For example, the phrase "a processor configured to perform A, B, and C" may mean a dedicated processor for performing those operations (e.g., an embedded processor) or a generic-purpose processor (e.g., a CPU or application processor) that is capable of performing those operations by executing one or more software programs stored in a memory device.

[0142] The terms used in this document are merely used to describe a particular embodiment and may not be intended to limit the scope of other embodiments. A singular expression may include a plural expression unless the context clearly indicates otherwise. Terms used herein, including technical or scientific terms, may have the same meaning as commonly understood by a person of ordinary skill in the art described in this document. Among the terms used in this document, terms defined in a general dictionary may be interpreted as having the same or similar meaning as the meaning they have in the context of the related art, and unless clearly defined in this document, they are not interpreted as ideal or overly formal. In some cases, even terms defined in this document may not be interpreted to exclude the embodiments of this document.

[0143] The touch input device according to various embodiments of the present document may include at least one of, for example, a smartphone, a tablet personal computer, a mobile phone, a video phone, an e-book reader, a laptop personal computer, a netbook computer, a mobile medical device, a camera, or a wearable device. According to various embodiments, the wearable device may include at least one of an accessory type (e.g., a watch, a ring, a bracelet, an anklet, a necklace, glasses, contact lenses, or a head-mounted device (HMD)), a textile or clothing integrated type (e.g., electronic clothing), a body-attached type (e.g., a skin pad or a tattoo), or a biologically implanted type (e.g., an implantable circuit).

[0144] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a controller for controlling a touch input device including a sensor unit and capable of acting as a stylus pen will be described as a controller according to an embodiment of the present invention with reference to the accompanying drawings.

[0145] In describing a controller according to an embodiment of the present invention, a pen and touch input system including a touch input device including a sensor unit and a control unit that controls the sensor unit, and a stylus pen that can operate with the touch input device will be described in detail.

[0146] FIG. 1a is a conceptual diagram showing a pen and touch input system including a stylus pen and a touch input device.

[0147] Referring to FIG. 1a, a stylus pen 10 can receive (or uplink) signals output from a touch input device 2 or a touch screen 20 in the vicinity of the touch screen 20 of the touch input device 2, and can transmit (or downlink) signals to the touch screen 20.

[0148] FIG. 1b is a diagram for explaining an uplink and a downlink in the pen and touch input system shown in FIG. 1a.

[0149] Referring to the left side of Fig. 1b, in the uplink, an electromotive force (V2 or Vemf) is generated in the coil inside the stylus pen 10 of Fig. 1a. Referring to the right side of Fig. 1b, in the downlink, an electromotive force (V1 or Vemf) is generated in the sensor part of the touch screen 20. That is, the coil inside the stylus pen and the sensor part of the touch input device act as a transformer with respect to each other.

[0150] FIG. 1c is a diagram illustrating the spacing between the + drive channel and the - drive channel in the uplink.

[0151] Referring to FIG. 1c, in the uplink, the interval between the + drive channel and the - drive channel has an optimal interval depending on the shape and position of the inductor inside the stylus pen. As a general design standard for a stylus pen, it is preferable that the interval between the + drive channel and the - drive channel is at least one channel apart (4 mm).

[0152] FIG. 2 is a diagram illustrating a signal transmission operation between a stylus pen and a touch input device.

[0153] Referring to FIG. 2( a ), the touch screen 20 a includes a digitizer 29 , a display panel 251 , a sensor portion 21 , and a window 22 .

[0154] In the case of an EMR (Electro-Magnetic Resonance) type pen among passive stylus pens, when a digitizer 29 transmits a magnetic signal B to an EMR type stylus pen 10a, a resonant circuit included in the stylus pen 10a resonates with the magnetic signal B. Then, the digitizer 29 receives an input of the resonated magnetic signal B from the stylus pen 10a.

[0155] The digitizer 29 may be attached under the display panel 251 and includes a flexible printed circuit board (FPCB) on which multiple conductive antenna loops are formed, and a ferrite sheet that blocks the magnetic field generated by the antenna loops and blocks eddy currents that may be generated in other electrical elements and components when the antenna loop forms a magnetic field.

[0156] The FPCB has a plurality of antenna loops in a plurality of layers for detecting the position where the resonant signal is input. Each antenna loop overlaps with at least one other antenna loop in the Z-axis direction. This makes the FPCB thick. Therefore, when the digitizer 29 is used, it is difficult to make the touch input device 2 thinner and more compact.

[0157] When such a digitizer 29 is mounted on the foldable / flexible touch input device 2, deformation may occur in the FPCB attached to the folded area when folding occurs. Repeated folding may cause stress to be applied to the wiring member forming the antenna loop, which may eventually result in damage to the wiring member. The ferrite sheet blocks the influence of the magnetic field generated by the antenna loop on the inside of the touch input device 2. The ferrite sheet is also thick, and is easily deformed when the touch input device 2 is folded, and may be damaged by repeated folding.

[0158] Referring to FIG. 2(b), the touch screen 20b includes a display panel 251, a sensor unit 21, and a window 22.

[0159] In the case of the stylus pen 10 including a resonant circuit, when the electrode (or pattern) of the sensor unit 21 transmits a magnetic signal B to the stylus pen 10, the resonant circuit included in the stylus pen 10 resonates with the magnetic signal B. Then, the electrode (or pattern) of the sensor unit 21 can receive an input of the resonated electromagnetic signal (E and / or B) from the stylus pen 10. When the electrode (or pattern) of the sensor unit 21 is formed of a metal mesh with low resistance, it is possible to detect the magnetic signal from the stylus pen 10.

[0160] Similarly, compared to the digitizer 29, the touch screen 20b does not require an additional unit or module for transmitting magnetic signals to the stylus pen 10, so the touch screen 20b can be made thinner, which is advantageous in terms of manufacturing costs.

[0161] Referring to FIG. 2( c ), a touch screen 20 c includes a loop coil 264 , a display panel 251 , a sensor portion 21 , and a window 22 .

[0162] In the case of the stylus pen 10 including a resonant circuit, when the loop coil 264 transmits a magnetic signal B to the stylus pen 10, the resonant circuit included in the stylus pen 10 resonates with the magnetic signal B. Then, the electrode (or pattern) of the sensor unit 21 can receive an input of the resonated electromagnetic signal (E and / or B) from the stylus pen 10.

[0163] Compared to the digitizer 29, the loop coil 264 does not receive the magnetic signal B for detecting the touch position, and therefore the wiring structure is simple and the touch screen 20c can be made thinner. This allows the touch input device 2 to be made thinner and more compact. In addition, the loop coil 264 can be formed in various sizes and positions, and therefore such a touch screen 20c can be applied to the foldable / flexible touch input device 2.

[0164] The loop coil 264 may include a substrate on which the antenna loop is located and a ferrite sheet. The antenna loop may be made of a conductive material such as copper or silver. The antenna loop may be located on the same layer as the sensor unit 21 in addition to the substrate, in which case the antenna loop may be made of a conductive material exhibiting high transmittance and low impedance such as metal mesh, ITO, graphene, silver nanowire, etc. The antenna loop may also be located under a window, in which case the substrate may not be included in the loop coil 264.

[0165] In the above, the sensor unit 21 may include a number of electrodes (or patterns) for detecting touch coordinates. For example, the sensor unit 21 may include a number of first touch electrodes for detecting touch coordinates in a first direction and a number of second touch electrodes for detecting touch coordinates in a second direction intersecting the first direction. Although the sensor unit 21 is shown in one layer in FIG. 2, the first touch electrodes and the second touch electrodes may be located in different layers, may be located overlapping each other, or may not be located overlapping each other, and a separate layer may be interposed between the first touch electrodes and the second touch electrodes, and is not limited thereto.

[0166] Referring to (d) of FIG. 2, a touch screen 20d includes a display panel 251, a sensor portion 21, and a window 22.

[0167] In the case of an active stylus pen 10' including a resonant circuit, the resonant circuit included in the active stylus pen 10' resonates using a power source (for example, a battery (including a secondary battery) for storing power and a capacitor such as an EDLC (electric double layered capacitor)) in the active stylus pen 10'. Then, the electrodes of the sensor unit 21 can receive the input of the resonated electromagnetic signal (E and / or B) from the stylus pen 10'. When the electrodes (or patterns) of the sensor unit 21 are formed of a metal mesh having a low resistance, it is possible to detect the magnetic signal from the stylus pen 10'. The active stylus pen 10' may include not only a resonant circuit for generating an electromagnetic signal, but also a circuit for outputting an electromagnetic signal (E and / or B) having a predetermined frequency using a power source. The active stylus pen 10' may also include both the resonant circuit and a circuit for outputting an electromagnetic signal (E and / or B) having a predetermined frequency.

[0168] The touch screen 20d can receive an electromagnetic signal from the stylus pen 10' without transmitting a magnetic signal to the stylus pen 10'. That is, the touch screen 20d does not require an additional unit or module for generating a signal for resonating a resonant circuit included in the stylus pen 10', so the touch screen 20d can be made thinner and smaller, and is advantageous in terms of power consumption and manufacturing costs.

[0169] Next, with reference to FIG. 3, a touch input device 2 according to an embodiment will be described.

[0170] FIG. 3 is a schematic block diagram of a touch input device capable of interacting with a stylus pen.

[0171] As shown, the touch input device 2 may include a wireless communication unit 210, a memory 220, an interface unit 230, a power supply unit 240, a display unit 250, a touch unit 260, and a control unit 270. The components shown in Fig. 3 are not essential for implementing a touch input device, so the touch input device described in this disclosure may have more or less components than those listed above.

[0172] More specifically, the wireless communication unit 210 among the components may include one or more modules that enable wireless communication between the touch input device 2 and a wireless communication system, between the touch input device 2 and another touch input device 2, or between the touch input device 2 and an external server. In addition, the wireless communication unit 210 may include one or more modules that connect the touch input device 2 to one or more networks.

[0173] Such a wireless communication unit 210 may include a wireless Internet module 211 and a short-range communication module 212 .

[0174] The wireless Internet module 211 is a module for wireless Internet connection and may be built into the touch input device 2. The wireless Internet module 211 is adapted to transmit and receive wireless signals through a communication network using wireless Internet technology. Examples of wireless Internet technology include Wireless LAN (WLAN), Wireless-Fidelity (Wi-Fi), Wireless Fidelity (Wi-Fi) Direct, Digital Living Network Alliance (DLNA), Wireless Broadband (WiBro), World Interoperability for Microwave Access (WiMAX), High Speed ​​Downlink Packet Access (HSDPA), High Speed ​​Uplink Packet Access (HSUPA), New Radio (NR), Long Term Evolution (LTE), and Long Term Evolution-Advanced (LTE-A), and the wireless Internet module 211 transmits and receives data using at least one of the wireless Internet technologies, including Internet technologies not listed above.

[0175] The short-range communication module 212 may support short-range communication using at least one of Bluetooth™, RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB (Ultra Wideband), ZigBee, NFC (Near Field Communication), Wi-Fi, Wi-Fi Direct, and Wireless Universal Serial Bus (Wireless USB) technologies for short-range communication. The short-range communication module 212 may support wireless communication between the touch input device 2 and a wireless communication system, between the touch input device 2 and a wireless communication enabled device, or between the touch input device 2 and a network in which an external server is located, via a short-range wireless communication network. The short-range wireless communication network may be a wireless personal area network.

[0176] Here, the wireless communication enabled device may be a mobile terminal (e.g., a smartphone, a tablet PC, a notebook, etc.) capable of exchanging data with (or linking with) the touch input device 2 according to the present invention. The near field communication module 212 may detect (or recognize) a wireless communication enabled device capable of communicating with the touch input device 2 in the vicinity of the touch input device 2. Furthermore, if the detected wireless communication enabled device is a device authenticated to communicate with the touch input device 2 according to an embodiment, the control unit 270 may transmit at least a portion of data processed by the touch input device 2 to the wireless communication enabled device via the near field communication module 212. Thus, a user of the wireless communication enabled device may use the data processed by the touch input device 2 via the wireless communication enabled device.

[0177] The memory 220 also stores data supporting various functions of the touch input device 2. The memory 220 may store a number of application programs (or applications) operated by the touch input device 2, and data and commands for the operation of the touch input device 2.

[0178] The interface unit 230 serves as a passageway for various kinds of external devices connected to the touch input device 2. The interface unit 230 may include at least one of a wired / wireless headset port, an external charger port, a wired / wireless data port, a memory card port, a port for connecting a device equipped with an identification module, an audio I / O (Input / Output) port, a video I / O port, and an earphone port.

[0179] The power supply unit 240, under the control of the control unit 270, receives an external power source or an internal power source and supplies power to each component included in the touch input device 2. The power supply unit 240 includes a battery, which may be a built-in battery or a replaceable battery.

[0180] The display unit 250 displays (outputs) information processed by the touch input device 2. For example, the display unit 250 may display execution screen information of an application program operated by the touch input device 2, or UI (User Interface) or GUI (Graphic User Interface) information based on such execution screen information.

[0181] The display unit 250 may include a liquid crystal display (LCD), an organic light-emitting diode (OLED) display, an e-ink display, a quantum-dot light-emitting display, a micro LED (Light-emitting diode) display, or the like.

[0182] The display unit 250 includes a display panel 251 that displays an image, and a display controller 252 that is connected to the display panel 251 and supplies signals for displaying an image to the display panel 251. For example, the display panel 251 may include a plurality of pixels connected to signal lines such as a plurality of scan lines and a plurality of data lines, and a scan driver / receiver that supplies scan signals to the scan lines, and the display controller 252 may include a data driver IC that generates data signals to be applied to the data lines, a timing controller that processes image signals and controls the overall operation of the display unit 250, a power management IC, etc.

[0183] The touch unit 260 senses a touch (or a touch input) applied to the touch area using a predetermined method, for example, a capacitive method. For example, the touch unit 260 may be configured to convert a change in capacitance, voltage, or current generated at a specific portion into an electrical input signal. The touch unit 260 may be configured to detect a position, area, capacitance at the time of touch, etc., touched by a touch object that applies a touch to the touch area on the touch unit 260. Here, the touch object is an object that applies a touch to the touch screen, and may be, for example, a body part of a user (a finger, a palm, etc.), a passive or active stylus pen 10, etc.

[0184] The touch unit 260 includes a touch panel 261 including the sensor unit 21 of FIG. 2, and a touch controller 262 that applies a driving signal to the touch panel 261, receives a sensing signal from the touch sensor, and transmits touch data to the control unit 270 and / or the display controller 252.

[0185] The touch controller 262 may include a first driver / receiver connected to at least one of the plurality of first touch electrodes of the sensor unit 21 of FIG. 2 to apply a driving signal and receive a sensing signal, a second driver / receiver connected to at least one of the plurality of second touch electrodes to apply a driving signal and receive a sensing signal, and an MCU (micro control unit) to control operations of the first driver / receiver and the second driver / receiver and to obtain a touch position using the sensing signals output from the first and second driver / receivers.

[0186] The touch controller 262 may be integrated with the control unit 270 (described later) into one IC, or may be integrated with the display controller 252 into one IC. Alternatively, the touch controller 262 may be integrated with the display controller 252 and the control unit 270 into one IC. The touch controller 262 and the control unit 270, the touch controller 262 and the display controller 252, or the touch controller 262, the display controller 252, and the control unit 270 may be integrated into one and named as a "control unit."

[0187] The display panel 251 and the touch panel 261 may be formed as a mutually layered structure or integrally, and may be referred to as a touch screen 20 .

[0188] The controller 270 may control driving of the touch input device 2 and output touch coordinate information in response to a touch sensing result of the touch input device 2. In addition, the controller 270 may change a frequency of a driving signal in response to a touch sensing result.

[0189] In addition to operations related to the application programs, the controller 270 typically controls the overall operation of the touch input device 2. The controller 270 processes signals, data, information, etc. input or output via the components described in detail above, and drives application programs stored in the memory 220 to provide or process appropriate information or functions to a user.

[0190] 3 in order to drive the application program stored in the memory 220. Furthermore, the controller 270 can operate at least two or more of the components included in the touch input device 2 in combination with each other to drive the application program.

[0191] Although it has been described above that the touch unit 260 is included in the touch input device 2 together with the display unit 250, the touch input device 2 may include only the touch unit 260.

[0192] FIG. 4 is a diagram illustrating a stylus pen according to an embodiment.

[0193] The stylus pens of FIG. 4 commonly include a resonant circuit portion 12 within a housing.

[0194] The resonant circuit unit 12 is an LC resonant circuit and can resonate with the driving signal output from the touch screen 20 of FIGS. 2 and 3. The driving signal may include a signal (e.g., a sine wave, a square wave, etc.) having a frequency corresponding to the resonant frequency of the resonant circuit unit 12. For resonance, the resonant frequency of the resonant circuit unit 12 and the frequency of the driving signal must be the same or very similar. The resonant frequency of the stylus pens 10a and 10b is determined by the design value of the resonant circuit unit 12 of the stylus pens 10a and 10b. When the sensor unit 21 of FIG. 2(b) or the loop coil 264 of FIG. 2(c) generates an electromagnetic field according to the driving signal, the resonant circuit unit 12 of the stylus pens 10a and 10b resonates using the signal received through a change in the magnetic field.

[0195] The elements of the stylus pens 10a and 10b may be accommodated in a housing. The housing may have a shape such as a cylinder, a polygonal prism, a pillar shape with at least a portion curved, an entasis shape, a frustum of pyramid shape, a circular truncated cone shape, etc., but is not limited thereto. The housing has an open interior, so that the elements of the stylus pens 10a and 10b, such as the resonant circuit unit 12, can be accommodated therein. Such a housing may be made of a non-conductive material.

[0196] 4(a), the EMR-type stylus pen 10a includes a resonant circuit section 12. The resonant circuit section 12 includes an inductor section 14 and a capacitor section 13. The inductor section 14 includes a ferrite core 115 and a coil 116 wound around the outer surface of the ferrite core 115.

[0197] The EMR type stylus pen 10a may further include a tip 11a. The tip 11a is the tip of the stylus pen 10a, and may be disposed to penetrate the ferrite core 115 as shown in FIG. 4(a), or may protrude from the ferrite core 115. The tip 11a may be a non-conductor, or may be a conductor, such as an electrode core made of a hard resin mixed with a conductive metal or conductive powder. Here, the tip 11a may or may not be electrically connected to the resonant circuit unit 12.

[0198] The ferrite core 115 may be, for example, a cylindrical ferrite material. The ferrite core 115 may have a through hole in the axial direction with a predetermined diameter (for example, 1 mm) for inserting and passing the tip 11a. Alternatively, the ferrite core 115 may be formed in the shape of a cylinder, a polygonal column, a column having at least a curved surface in a portion thereof, a cylindrical column, a truncated pyramid, a truncated cone, a toroid, a ring, or the like.

[0199] The coil 116 may be wound over the entire length in the axial direction of the ferrite core 115 or over a portion of the length. The coil 116 is electrically connected to the capacitor unit 13.

[0200] The capacitor unit 13 may include a plurality of capacitors connected in parallel. Each capacitor on the printed circuit board may have a different capacitance and may be trimmed during the manufacturing process.

[0201] 4(b), an ECR (Electrically Coupled Resonance) type stylus pen 10b includes a conductive tip 11b and a resonant circuit unit 12. The resonant circuit unit 12 may include an inductor unit 14 and a capacitor unit 13 and may be grounded. The inductor unit 14 includes a ferrite core 115 and a coil 116 wound around the outer surface of the ferrite core 115.

[0202] The conductive tip (11b) may be formed entirely or at least partially from a conductive material (eg, metal, conductive rubber, conductive fabric, conductive silicone, etc.), but is not limited thereto.

[0203] The coil 116 may be wound over the entire length in the axial direction of the ferrite core 115 or over a portion of the length. The coil 116 is electrically connected to the capacitor unit 13.

[0204] The capacitor unit 13 may include a plurality of capacitors connected in parallel. Each capacitor on the printed circuit board may have a different capacitance and may be trimmed during the manufacturing process.

[0205] FIG. 5 is a conceptual diagram specifically illustrating the inductor portion of the stylus pen shown in FIGS.

[0206] Referring to FIG. 5, the inductor section 14 includes a ferrite core 115 and a coil 116 wound around the ferrite core 115 .

[0207] At this time, the inductance of the inductor unit 14 is determined by the following Equation 1.

[0208] As can be seen from TIFF2025063880000002.tif21130 <Equation 1>, the inductance (L) is proportional to the permeability of the ferrite core 115, the cross-sectional area of ​​the coil 116, and the power of the number of windings, and is inversely proportional to the length of the windings of the coil 116.

[0209] The design of the inductor section 14 in the resonant circuit section 12 housed in the stylus pen shown in Figures 4(a) and (b) is very important. In particular, in the design of the inductor section 14, the inductance (L) and the Q value are very important parameters, as shown in Figure 6. Here, the Q value is a quantity that indicates the coil characteristics as a resonant circuit element, and is expressed as follows: JPEG2025063880000003.jpg835 where L and R are the inductance and resistance of the coil, respectively, and f is the frequency. The higher the Q value of a coil, the sharper the resonance characteristics can be obtained.

[0210] In the design of the stylus pen shown in Figures 4(a) and (b), L must have a sufficiently large self-resonance frequency for the frequency to be used, and the Q value should preferably have a maximum value at the frequency to be used. To satisfy this, the material of the ferrite core, the type of coil wire, and the winding scheme must be optimized. Also, a method is required that can obtain a high output signal while maintaining a thin pen diameter.

[0211] In the following embodiment, a stylus pen design method that is most optimized among a number of ferrite core materials, coil wire types, and winding schemes will be described.

[0212] (1) Ferrite core material In this embodiment, the ferrite core is made of manganese (Mn) and nickel (Ni).

[0213] (2) Wire type The types of coil wire used in this embodiment were enameled wire and Litz wire.

[0214] 7, enameled wire 100 is an electric wire made by covering the surface of copper wire 101 with insulating enamel 102 and heating it at high temperature, and is used for windings and wiring in electric devices, communication devices, electric meters, etc. In this embodiment, an enameled wire with a total thickness (T) of 0.2 mm, a wire diameter (Φ) of 0.18 mm, and a covering thickness (t) of 0.01 mm was used.

[0215] As shown in Fig. 8, Litz wire 200 is a special insulated wire made by twisting together several thin insulated wires 100 (e.g., enameled wires) with a diameter of about 0.1 mm into one wire, and then covering it with an insulating coating 201 made of nylon or the like. Litz wire 200 can reduce the skin effect by increasing the surface area, and is used for coils in high-frequency circuits.

[0216] In this embodiment, a Litz wire having a total thickness (T) of 0.2 mm, a wire diameter (Φ) of 0.06 mm, and a coating thickness (t) of 0.007 mm was used.

[0217] (3) Winding method In the embodiment of the present invention, in order to obtain a sufficient inductance value (i.e., a sufficient number of windings) in the limited space of a stylus pen, a winding method having a multi-layer winding structure is used. Specifically, as shown in (A) and (B) of FIG. 9, two types of multi-layer winding methods are used.

[0218] The winding scheme in Figure 9(A) is the simplest winding scheme, which is a sequential layer winding scheme in which the winding of the layer immediately above is started after the winding of the lower layer is finished. In this case, the winding of the layer immediately above starts at the point where the winding of the previous layer ends, and this will be referred to as a U-type winding scheme below.

[0219] The winding scheme of FIG. 9(B) is an alternate layer winding scheme in which adjacent winding layers are alternately wound, and adjacent layers are wound in a zigzag pattern. Hereinafter, this is referred to as a zigzag type winding scheme. Specifically, after the second layer winding is sequentially wound on the first layer winding, the third layer winding is wound between the first layer winding and the second layer winding, the fourth layer winding is wound on the second layer winding, and the fifth layer winding is wound between the second layer winding and the fourth layer winding. Such a zigzag type winding scheme has an advantage that it can minimize the voltage difference between adjacent layers and reduce the winding self-capacitance. At this time, the winding self-capacitance, which is a type of parasitic capacitance, is a parameter that indicates the electric field energy stored in the winding.

[0220] Comparative experiment 1 (Comparison of characteristic values ​​by material) The coil wire type was enameled wire, and the coil was wound using the U-type winding method. The ferrite core material was changed to manganese, nickel, and magnesium, and the Q value was measured.

[0221] As a result of the measurements, there was almost no difference in the Q value characteristics of each core material, and the measured Q value was far too low to be realized as a product.

[0222] Comparative experiment 2 (Comparison of characteristic values ​​by winding type) The Q value was measured for inductors 1 and 2, which were manufactured with a ferrite core made of manganese (Mn), wound using a U-type winding method, and with the coil wire types being enameled wire and Litz wire, respectively.

[0223] FIG. 8 is a graph showing the Q values ​​of inductors 1 and 2 measured by changing the frequency using a KEYSIGHT TECHNOGIES E4980A precision LCR meter.

[0224] In Figure 10, a is a waveform showing the change in Q value versus frequency for inductor 1 (manganese core / enamel wire / U-type winding method), and b is a waveform showing the change in Q value versus frequency for inductor 2 (manganese core / litz wire / U-type winding method).

[0225] For inductor 2 made from litz wire, the Q value reaches nearly its maximum value at a frequency of about 400 kHz (frequency f1), while for inductor 1 made from enamel wire, the Q value reaches nearly its maximum value at a frequency of about 150 kHz (frequency f2).

[0226] Comparing Figures 10a and 10b, we can see that the maximum Q value of inductor 2 is approximately 1.5 times higher than the maximum Q value of inductor 1. This shows that litz wire is superior to enamel wire as an inductor coil that forms the resonant circuit of a stylus pen.

[0227] However, the maximum Q value of inductor 2 measured in comparative experiment 2 was only about half the target value (Qtarget) required for commercialization.

[0228] Comparative experiment 3 (Comparison of characteristic values ​​by winding method) The Q value was measured for inductors 3 to 5, which were manufactured by changing the ferrite core material to manganese (Mn), changing the wire type to enameled wire and Litz wire, and changing the winding method to U type and zigzag type.

[0229] FIG. 11 is a graph showing the Q values ​​of inductors 3 to 5 measured by changing the frequency using a KEYSIGHT TECHNOGIES E4980A precision LCR meter.

[0230] In Figure 11, a is a waveform showing the change in Q value versus frequency for inductor 3 (manganese core / enamel wire / U-type winding method), b is a waveform showing the change in Q value versus frequency for inductor 4 (manganese core / enamel wire / zigzag-type winding method), and c is a waveform showing the change in Q value versus frequency for inductor 5 (manganese core / litz wire / zigzag-type winding method).

[0231] As can be seen from the waveform c in Figure 11, inductor 5 made with the litz wire / zigzag winding method, the Q value reaches nearly its maximum value at a frequency near 300 kHz (frequency f3). Inductor 4 made with the enamel wire / zigzag winding method and inductor 3 made with the enamel wire / U-type winding method, the Q value reaches nearly its maximum value at a frequency near 150 kHz (frequency f2).

[0232] 11(a), (b), and (c) show that the maximum Q value of inductor 5 is approximately 1.5 times higher than the maximum Q value of inductor 4, and more than twice as high as the maximum Q value of inductor 3. This shows that the zigzag-type winding method is superior to the U-type winding method for the inductor that forms the resonant circuit of the stylus pen.

[0233] However, the level was only about 3 / 4 of the target value (Qtarget) required for commercialization of inductor 5 (manganese core / litz wire / zigzag type winding method) measured in comparative experiment 2.

[0234] Comparative experiment 4 (Comparison of characteristic values ​​by core material) In this embodiment, manganese and nickel are used as the material for the ferrite core. Normally, nickel has a magnetic permeability of 200 to 300, while manganese has a magnetic permeability of 3,000 to 5,000.

[0235] Since manganese used in this embodiment has a magnetic permeability about 15 times higher than nickel, assuming that the cross-sectional area and length of the coil are the same, the number of windings of manganese can be reduced by about 4 times compared to the number of windings of nickel to obtain the same inductance value. Therefore, from the viewpoint of the number of windings alone, it can be seen that using manganese is more effective than nickel.

[0236] Meanwhile, since the inductor unit 14 has a complicated structure including a coil wound around a core, a parasitic capacitance is additionally formed, which reduces the Q value and thus reduces the amplitude of the resonant signal.

[0237] Parasitic capacitance formed in the inductor section 14 may occur between the wound coils and between the core and the coil, but by adopting the zigzag type winding method as described above, the parasitic capacitance between the wound coils can be reduced.

[0238] Meanwhile, in this embodiment, in order to reduce the parasitic capacitance between the core and the coil, core materials having a lower dielectric constant than manganese were tested, and as a result of the testing, it was found that nickel core is the optimal material for the ferrite core.

[0239] The important physical property of manganese and nickel, which are mainly used as ferrite core elements, is permeability, which has a significant effect on the inductance value as shown in <Formula 1>. However, permittivity is a physical property that is of little interest in manganese and nickel as ferrite elements, and in fact, in the case of nickel, there is no related information even on the data sheet provided by the manufacturer.

[0240] In this embodiment, in order to confirm the permittivity of manganese and nickel, the permittivity of manganese and nickel is measured using an E4980A precision LCR meter from KEYSIGHT TECHNOGIES, and the measurement results are shown in Table 1 below. [Table 1]

[0241] Measurement 1 and Measurement 2 were measured using the same KEYSIGHT TECHNOGIES E4980A precision LCR meter, and Measurement 1 shows the dielectric constant automatically calculated by the measurement software. Measurement 1 shows that the dielectric constant of manganese is 2400, but the dielectric constant of nickel is not measured.

[0242] Measurement 2 was a method of calculating the dielectric constant by measuring the capacitance, area, and distance between ferrite cores. According to Measurement 2, the dielectric constant of manganese was measured to be 8300, and the dielectric constant of nickel was measured to be 2.

[0243] There was a large difference in the dielectric constant between Measurement 1 and Measurement 2, and in particular, in the case of Measurement 2, it was confirmed that there was a considerable amount of error due to capacitance, area, distance, etc. However, the results of Measurements 1 and 2 show that nickel has a dielectric constant at least 1 / 1000 smaller than manganese.

[0244] In Comparative Experiment 4, the Q value was measured for Inductor 6 and Inductor 7, which were manufactured by changing the winding method to a U type and a zigzag type with the ferrite core material changed to nickel and the wire type changed to Litz wire.

[0245] FIG. 12 is a graph showing the Q values ​​of the inductors 6 and 7 measured by changing the frequency using a KEYSIGHT TECHNOGIES E4980A precision LCR meter.

[0246] In FIG. 12, a is a waveform showing the change in Q value versus frequency for inductor 6 (nickel core / litz wire / U-type winding method), and b is a waveform showing the change in Q value versus frequency for inductor 7 (nickel core / litz wire / zigzag-type winding method).

[0247] As can be seen from the waveform in Figure 12b, inductor 7, which was made using the nickel core / Litz wire / zigzag winding method, has a Q value that is nearly maximum at a frequency of about 400 kHz (frequency f5). Inductor 6, which was made using the nickel core / Litz wire / U-type winding method, has a Q value that is nearly maximum at a frequency of about 200 kHz (frequency f6). Comparing Figures 11a and b, it can be seen that the maximum Q value of inductor 7 is about twice as high as the maximum Q value of inductor 6.

[0248] On the other hand, it was found that the maximum Q value of inductor 7 (nickel core / litz wire / zigzag type winding method) measured in comparative experiment 4 almost reached the target value (Qtarget) required for commercialization.

[0249] In the above-described comparative experiments 1 to 4, inductors were manufactured and the Q value was tested while changing the combination of ferrite core material, coil wire type, and winding scheme, and the test results showed that the highest Q value was obtained when the inductor part of the capacitive resonant stylus pen was designed with a nickel core, Litz wire, and zigzag type winding scheme. It was also found that the maximum Q value of the inductor manufactured with such a combination reached the target value (Qtarget) for commercialization.

[0250] Meanwhile, in this embodiment, a nickel core was used as the ferrite core, and a Litz wire was used as the type of wire for the core. However, similar results would be obtained if a material having a dielectric constant of 1000 or less was used as the ferrite core other than the nickel core, and if a wire in the form of one coil covering two or more insulated wire strands was used other than the Litz wire.

[0251] Before describing in detail the touch input device in the pen and touch input system according to an embodiment of the present invention, the reason why the output voltage (Vout) of a CVA (Capacitor Voltage Amplitude) changes depending on the position of a stylus pen on a touch screen will be described below.

[0252] FIG. 13 is a schematic diagram for explaining how an output voltage (Vout) of a CVA (Capacitor Voltage Amplitude) changes depending on the position of a stylus pen 10 on a conventional touch screen.

[0253] Referring to FIG. 13, the reason why the CVA output varies depending on the position of the stylus pen 10 on the touch screen is that the impedance ratio on both sides of the sensing line centered on the stylus pen 10 changes.

[0254] Based on the long axis of a conventional touch screen, the resistance (R) of a Metal Mesh touch sensor is about 1.2k (ohm) and the capacitance (C) is about 250pF.

[0255] Based on 10 distributed models, at a driving frequency of 300kHz, the impedance of the capacitor is about 200 times higher than that of the resistor. JPEG2025063880000005.jpg is larger than 10143. Therefore, the capacitor is the main culprit.

[0256] Figure 14 is a diagram for explaining through current sensing that the output voltages (Vout1, Vout2) of the CVA differ depending on the position of the stylus pen 10 in Figure 13, and Figure 15 is a diagram for explaining through voltage sensing that the output voltages (Vout1, Vout2) of the CVA differ depending on the position of the stylus pen 10 in Figure 13.

[0257] 14 and 15, the output voltage of the CVA varies depending on the position of the stylus pen 10 on the sensing line. That is, the closer the stylus pen 10 is to the sensing circuit unit 50, the larger the output voltage of the CVA is, and the farther the stylus pen 10 is from the sensing circuit unit 50, the smaller the output voltage of the CVA is.

[0258] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, touch input devices according to various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0259] FIG. 16 is a schematic diagram of a touch input device according to one embodiment of the present invention.

[0260] Referring to FIG. 16, a touch input device according to an embodiment of the present invention includes a sensor unit 100 and a control unit 500.

[0261] The sensor unit 100 includes a number of patterns (or a number of electrodes). Here, the sensor unit 100 in this drawing is an embodiment of the sensor unit 21 shown in FIG.

[0262] The sensor unit 100 may include a number of first to fourth patterns 101, 102, 103, and 104.

[0263] The first pattern 101 has a shape extending along a first direction. In Fig. 16, the first direction is shown as a major axis, but is not limited thereto. For example, the first direction may be a minor axis.

[0264] The first pattern 101 may include a plurality of main pattern portions and a connecting pattern portion connecting two adjacent main pattern portions among the plurality of main pattern portions. Here, the main pattern portion may have a diamond shape, but is not limited thereto, and may have various shapes including the connecting pattern portion and other shapes.

[0265] The first pattern 101 may have an opening in which the second pattern 102 is disposed. The shape of the opening may correspond to the outer shape of the first pattern 101.

[0266] The first pattern 101 may have a structure surrounding the second pattern 102. Here, the surrounding structure includes not only the first pattern 101 completely surrounding the second pattern 102 in one plane, but also the first pattern 101 surrounding most of the second pattern 102 except for a part of the second pattern 102 in one plane.

[0267] The first pattern 101 is disposed at a predetermined distance from the second pattern 102 .

[0268] The second pattern 102 is disposed adjacent to the first pattern 101. For example, the second pattern 102 may be disposed inside the first pattern 101.

[0269] The second pattern 102 may include a plurality of main pattern portions and a connecting pattern portion connecting two adjacent main pattern portions among the plurality of main pattern portions. Here, the main pattern portion may have a diamond shape, but is not limited thereto, and may have various shapes including the connecting pattern portion and other shapes.

[0270] The main pattern portion of second pattern 102 may have a shape corresponding to that of the main pattern portion of first pattern 101 , and the connecting pattern portion of second pattern 102 may have a shape corresponding to that of the connecting pattern portion of first pattern 101 .

[0271] A large number of first patterns 101 and second patterns 102 are arranged parallel to each other.

[0272] One end of the first patterns 101 is electrically connected to the control unit 500, and the other end is electrically open. Here, the one end is relatively close to the control unit 500, and the other end is relatively far from the control unit 500. In the following description, the one end may be referred to as a first end and the other end as a second end. One end of the first patterns 101 may be electrically connected to the control unit 500 via a conductive trace.

[0273] One end of the second patterns 102 may be electrically connected to the control unit 500, and the other end may be electrically connected through a via. Here, the vias at the other ends of the second patterns 102 may be electrically connected through a conductive trace. One end is relatively close to the control unit 500, and the other end is relatively far from the control unit 500. Here, if the other ends of the second patterns 102 are electrically connected to each other, the capacitance of each second pattern 102 is added, and the overall impedance is reduced. Therefore, it has an effect that the other ends of the second patterns 102 are AC GND.

[0274] Meanwhile, although not shown in the drawing, the other ends of the plurality of second patterns 102 electrically connected to each other may be grounded.

[0275] Although not shown in the drawings, the other ends of the second patterns 102 may not be electrically connected to each other, and a predetermined capacitor may be connected to the other end of each of the second patterns 102 .

[0276] At least a part of the first pattern 101 and at least a part of the second pattern 102 are disposed in the same layer. For example, the first pattern 101 and the second pattern 102 may be disposed in the same layer. The first pattern 101 and the second pattern 102 can be formed in the same layer using a metal mesh.

[0277] The third pattern 103 has a shape extending along the second direction. In Fig. 16, the second direction is shown as the minor axis, but is not limited thereto. For example, the second direction may be the major axis.

[0278] The third pattern 103 may include a plurality of main pattern portions and a connecting pattern portion connecting two adjacent main pattern portions among the plurality of main pattern portions. Here, the main pattern portion may have a diamond shape, but is not limited thereto, and may have various shapes different from the connecting pattern portion.

[0279] The third pattern 103 may have an opening in which the fourth pattern 104 is disposed. The shape of the opening may correspond to the outer shape of the third pattern 103. The third pattern 103 may have a structure surrounding the fourth pattern 104. The third pattern 103 is disposed at a predetermined distance from the fourth pattern 104.

[0280] The fourth pattern 104 is disposed adjacent to the third pattern 103. For example, the fourth pattern 104 may be disposed inside the third pattern 103. The fourth pattern 104 may include a plurality of main pattern portions and a connecting pattern portion connecting two adjacent main pattern portions among the plurality of main pattern portions. Here, the main pattern portion may have a diamond shape, but is not limited thereto, and may have various shapes different from the connecting pattern portion.

[0281] The main pattern portion of fourth pattern 104 may have a shape corresponding to that of the main pattern portion of third pattern 103 , and the connecting pattern portion of fourth pattern 104 may have a shape corresponding to that of the connecting pattern portion of third pattern 103 .

[0282] A large number of third patterns 103 and fourth patterns 104 are arranged parallel to each other.

[0283] One end of each of the third patterns 103 is electrically connected to the control unit 500, and the other end is electrically open. Here, the one end is relatively close to the control unit 500, and the other end is relatively far from the control unit 500. One end of each of the third patterns 103 may be electrically connected to the control unit 500 via a conductive trace.

[0284] One end of the plurality of fourth patterns 104 may be electrically connected to the control unit 500, and the other end may be electrically connected through a via. The vias at the other ends of the plurality of fourth patterns 104 may be electrically connected through a conductive trace. One end is relatively close to the control unit 500, and the other end is relatively far from the control unit 500. If the other ends of the plurality of fourth patterns 104 are electrically connected to each other, the capacitance of each fourth pattern 104 is added, and the overall impedance is reduced. Therefore, the other ends of the plurality of fourth patterns 104 have the effect of being AC GND.

[0285] Meanwhile, the other ends of the fourth patterns 104 electrically connected to each other may be grounded.

[0286] Although not shown in the drawings, the other ends of the fourth patterns 104 may not be electrically connected to each other, and a predetermined capacitor may be connected to the other end of each of the fourth patterns 104 .

[0287] At least a part of the third pattern 103 and at least a part of the fourth pattern 104 are disposed in different layers. For example, the third pattern 103 and the fourth pattern 104 may be disposed in the same layer. The third pattern 103 and the fourth pattern 104 may be formed in the same layer using a metal mesh. Here, the third pattern 103 and the fourth pattern 104 may be disposed in a layer different from the first pattern 101 and the second pattern 102. For example, the first pattern 101 and the second pattern 102 may be disposed in a first layer, and the third pattern 103 and the fourth pattern 104 may be disposed in a second layer different from the first layer.

[0288] The controller 500 is electrically connected to the sensor unit 100 and can control the operation of the sensor unit 100. The controller 500 and the sensor unit 100 may be electrically connected to each other via a conductive trace.

[0289] Here, the control unit 500 may be the touch controller 262 shown in FIG. 3, but is not limited thereto. The control unit 500 may be an integrated unit of the touch controller 262 and the display controller 252 shown in FIG. 3, an integrated unit of the touch controller 262 and the control unit 270 shown in FIG. 3, or an integrated unit of the touch controller 262, the display controller 252, and the control unit 270 shown in FIG. 3. Alternatively, the controller 500 may be a separate controller included in the sensor unit 100. Therefore, the controller 500 in the present invention is not limited to the touch controller 262 or the controller 270 shown in FIG. 3, and a unit capable of controlling not only the sensor unit 100 but also the sensor units of the following embodiments may be named "controller".

[0290] The control unit 500 may include a number of driving circuits and a number of sensing circuits. The number of driving circuits may include a driving circuit for touch sensing and a driving circuit for driving a stylus. The number of sensing circuits may include a sensing circuit for touch sensing and a sensing circuit for stylus sensing. Here, some of the sensing circuits may perform both touch sensing and stylus sensing.

[0291] The controller 500 may control the sensor unit 100 to operate in any one of a touch sensing mode, an antenna driving mode, and a stylus sensing mode. The controller 500 may connect a plurality of driving / sensing circuits to the sensor unit 100 according to each mode, and control driving signals applied to the plurality of driving circuits. To this end, the controller 500 may include a plurality of switches for electrically connecting the plurality of driving / sensing circuits to the sensor unit 100.

[0292] Each mode will now be described with reference to FIGS.

[0293] FIG. 17 illustrates a case where the touch input device illustrated in FIG. 16 operates in a touch sensing mode (or a 2D sensing mode).

[0294] 16 and 17, in a touch sensing mode, the controller 500 can electrically connect a number of driving circuits for touch sensing to the first pattern 101 of the sensor unit 100. The controller 500 can control a number of switches sw to electrically connect the conductive traces connected to the first pattern 101 to a number of driving circuits.

[0295] In addition, the control unit 500 may electrically connect a plurality of sensing circuits for touch sensing to the third pattern 103 of the sensor unit 100. The control unit 500 may control a plurality of switches sw to electrically connect conductive traces connected to a plurality of the third patterns 103 to a plurality of sensing circuits.

[0296] In the touch sensing mode, the controller 500 simultaneously or sequentially applies driving signals (or touch driving signals) for touch sensing to at least one first pattern among the plurality of first patterns 101, and receives sensing signals (or touch sensing signals) from at least one third pattern among the plurality of third patterns 103. The plurality of sensing circuits of the controller 500 electrically connected to the plurality of third patterns 103 may output information on capacitance change amount included in the input sensing signal as a predetermined voltage value. The controller 500 may process the output voltage value to detect a touch position.

[0297] 17, the control unit 500 is not electrically connected to the second patterns 102, but the control unit 500 can be electrically connected to the second patterns 102 so that capacitive coupling between the first patterns 101 and the second patterns 102 does not occur. In this case, the control unit 500 can control the second patterns 102 to apply the same driving signal as the driving signal applied to the first patterns 101. Alternatively, the control unit 500 can control the second patterns 102 to apply a predetermined reference potential when the driving signal is applied to the first patterns 101.

[0298] FIG. 18 illustrates the touch input device illustrated in FIG. 16 operating in an antenna driving mode (or a stylus driving mode or a stylus uplink mode).

[0299] 16 and 18, in the antenna driving mode, the control unit 500 can electrically connect a number of driving circuits for driving the antenna to a number of second patterns 102 of the sensor unit 100. The control unit 500 can electrically connect conductive traces connected to the number of second patterns 102 to a number of driving circuits by controlling a number of switches sw.

[0300] The control unit 500 can control driving signals (or pen driving signals) output from each driving circuit unit connected to the second patterns 102 .

[0301] For example, the control unit 500 may control the first driving circuit unit among the multiple driving circuit units connected to the multiple second patterns 102 to output a pulse signal of a predetermined frequency, control the second driving circuit unit not to output any pulse signal, and control the third driving circuit unit to output an inverted pulse signal having a phase opposite to that of the pulse signal output from the first driving circuit unit. In this case, a current loop is formed between the second pattern 102 electrically connected to the first driving circuit unit and the second pattern 102 electrically connected to the third driving circuit unit. A magnetic field is generated by the formed current loop, and the resonant circuit unit of the stylus pen adjacent to the sensor unit 100 can be resonated and driven by the magnetic field.

[0302] The control unit 500 may control any two of the multiple driving circuits electrically connected to the multiple second patterns 102 to output mutually opposing driving signals (e.g., pulse signals). Thus, the control unit 500 may change and set the size and position of the current loop in various ways. For example, when the control unit 500 detects the position of a stylus pen close to the sensor unit 100, it may control the driving circuits electrically connected to two second patterns around the position of the stylus pen to output mutually opposing driving signals, and when the control unit 500 cannot detect the position of the stylus pen, it may control the driving circuits electrically connected to two second patterns located on the outermost sides of the multiple second patterns 102 to output mutually opposing driving signals.

[0303] The control unit 500 can also form two or more current loops simultaneously. This will be described with reference to FIG.

[0304] Figures 19(a) to 19(c) are diagrams for explaining various methods in which the control unit 500 applies a pen driving signal for driving a stylus pen to a plurality of second patterns 102 shown in Figure 16. For reference, in Figures 19(a) to 19(c), one second pattern 102 shown in Figure 16 is simply shown by one line Ch, and each line Ch corresponds to one channel.

[0305] 19(a) shows a case where the stylus pen 50 is located at the center (not at the edge) of the sensor unit 100 shown in FIG. 16, for example, on the fifth channel Ch5. In this case, the control unit 500 can control a number of driving circuits so that a pulse signal and an inverted pulse signal (or ground) are applied to the same number of channels Ch2, Ch3, Ch4 / Ch6, Ch7, Ch8 on both sides of the position of the stylus pen 50. Specifically, the control unit 500 can control so that a pulse signal is applied to the three second to fourth channels Ch2, Ch3, Ch4 located on the left side of the stylus pen 50, and so that an inverted pulse signal is applied to the three sixth to eighth channels Ch6, Ch7, Ch8 located on the right side of the stylus pen 50. Here, in (a) of Fig. 19, a pulse signal and an inverted pulse signal (or ground) are applied to three channels on each side of the stylus pen 50, but this is not limiting. For example, in (a) of Fig. 19, a pulse signal and an inverted pulse signal (or ground) may be applied to two or one channels on each side of the stylus pen 50, or a pulse signal and an inverted pulse signal (or ground) may be applied to four or more channels.

[0306] FIG. 19(b) shows a case where the stylus pen 50 is located at the edge of the sensor unit 100 shown in FIG. 16, for example, between the 0th channel Ch0 and the 1st channel Ch1. Compared to FIG. 19(a), the control unit 500 cannot apply a pulse signal and an inverted pulse signal (or ground) to the same number of channels on the left and right sides of the stylus pen 50. In this case, the control unit 500 can control the stylus pen 50 to apply a pulse signal and an inverted pulse signal (or ground) to different numbers of channels on the left and right sides of the stylus pen 50. Specifically, the control unit 500 can control the 0th channel Ch0 to apply a pulse signal and an inverted pulse signal to the 1st to 3rd channels Ch1, Ch2, and Ch3. Although not shown in the drawing, when the stylus pen 50 is located at the outermost edge on the left side of the 0th channel Ch0, the control unit 500 can also control the 0th to 2nd channels Ch0, Ch1, and Ch2 to be applied with inverted pulse signals.

[0307] In FIG. 19(a) and (b), the more the channels Ch0, Ch1, ..., Ch19, the more terminals of the control unit 500 for driving each channel are required, and the configuration of the driving circuit unit in the control unit 500 becomes complicated. Therefore, at least two of the channels Ch0, Ch1, ..., Ch19 that are close to each other can be electrically connected to be driven as one channel. Specifically, as shown in FIG. 19(c), two channels are electrically connected to form one channel. In this configuration, the same signal is applied to the two electrically connected channels at the same time. FIG. 19(c) shows 20 channels Ch0, Ch1, ..., Ch19 electrically connected in pairs to form 10 channels. Although not shown in the drawing, it is possible to electrically connect three channels and electrically connect the remaining two to form 7 channels, or to electrically connect four channels to form 5 channels. FIG. 20 illustrates the touch input device illustrated in FIG. 16 operating in a stylus sensing mode (or a stylus downlink mode).

[0308] 16 and 20, in a stylus sensing mode, the controller 500 can electrically connect a number of sensing circuits for stylus sensing to the first pattern 101 and the third pattern 103 of the sensor unit 100. The controller 500 can control a number of switches sw to electrically connect conductive traces connected to the first pattern 101 and the third pattern 103 to a number of sensing circuits.

[0309] Due to the configuration of the sensor unit 100, the touch input device according to the embodiment of the present invention has an advantage that in the stylus sensing mode, the output voltage values ​​of the multiple sensing circuits are hardly changed depending on the position of the stylus pen on the sensor unit 100. The specific principle of this will be described with reference to (a) to (f) of FIG.

[0310] 21(a) to (f) are diagrams for roughly explaining the operation principle of the stylus sensing mode of FIG. 20. In FIG.

[0311] FIG. 21(a) is a circuit diagram that roughly models any one of the first patterns 101 shown in FIG. 20 and the sensing circuit section of the control unit 500 electrically connected thereto, and FIG. 21(b) is a circuit diagram that roughly models the second pattern 102 arranged inside any one of the first patterns 101.

[0312] FIG. 21(c) is a voltage distribution graph in the circuit diagram of FIG. 21(a), and FIG. 21(d) is a voltage distribution graph in the circuit diagram of FIG. 21(b).

[0313] Referring to (a) and (c) of Figure 21, when a stylus pen approaches any point A on the first pattern 101 that is as far away as possible from the sensing circuit unit, a voltage (Vemf, hereinafter referred to as "induced voltage") induced by the signal emitted from the stylus pen is generated at the point A.

[0314] When an induced voltage (Vemf) occurs at point A, the equivalent capacitance of the first pattern 101 viewed to the left of point A becomes smaller, and the equivalent impedance becomes larger. Therefore, most of the induced voltage (Vemf) is applied to the left of point A, and a voltage close to 0 (V) is applied to the right of point A, and almost no current flows. Moreover, the voltage close to 0 (V) on the right of point A gradually decreases due to the equivalent resistance of the first pattern 101, and almost no voltage is applied to the input terminal of the sensing circuit unit.

[0315] 21(b) and (d), when an induced voltage (Vemf) occurs at point A, the other ends of the second patterns 102 on the left side of point A are electrically connected to each other, so the equivalent capacitance viewed from the left side of point A becomes large and the equivalent impedance approaches almost 0. Therefore, 0 (V) is applied to the left side of point A, and one end of the second pattern 102 on the right side of point A is open, so no voltage drop occurs in the equivalent resistance and Vemf is applied as is.

[0316] 21(c) and (d), it can be seen that there is a potential difference of Vemf between the first pattern 101 and the second pattern 102 at any position. The potential difference of Vemf between the first pattern 101 and the second pattern 102 causes capacitive coupling between the first pattern 101 and the second pattern 102. Due to the capacitive coupling, a current flows from the second pattern 102 to the first pattern 101 as shown in FIG. 21(e). As shown in FIG. 21(a), the current generated in the first pattern 101 itself gradually decreases as the position of the stylus pen moves farther away from the sensing circuit unit of the control unit 500, but since a current flows from the second pattern 102 to the first pattern 101, the current output from the first pattern 101 to the sensing circuit unit of the control unit 500 becomes almost the same as the position of the pen. Therefore, the controller 500 can sense the position of the stylus pen through the sensing circuit unit electrically connected to the first pattern 101 and the third pattern 103 .

[0317] 21(a) to 21(e), even if point A moves to the left or right, the potential difference between the first pattern 101 and the second pattern 102 is constant as Vemf. Therefore, regardless of whether the position of the stylus pen on the sensor unit 100 is close or far from the sensing circuit unit, the control unit 500 can sense the stylus pen from a constant signal output from the sensing circuit unit.

[0318] 21(e), the current flowing from the second pattern 102 to the first pattern 101 is due to capacitive coupling, but this is not limited to this. For example, the current flowing from the second pattern 102 to the first pattern 101 can also be due to magnetic coupling.

[0319] In order for the sensor unit 100 of the touch input device shown in Fig. 16 to drive and sense the stylus pen, a number of first to fourth patterns 101, 102, 103, and 104 may be used in various combinations. Various combinations are as shown in Table 2 below. In Table 2 below, "1" indicates a number of first patterns 101, "2" indicates a number of second patterns 102, "3" indicates a number of third patterns 103, and "4" indicates a number of fourth patterns 104. [Table 2]

[0320] Referring to Table 2 above, in various combinations (No. 1 to No. 32), the multiple first patterns 101 and the multiple third patterns 103 sense a touch of an object such as a finger. Specifically, the multiple first patterns 101 operate as touch driving electrodes and the multiple third patterns 103 operate as touch receiving electrodes under the control of the controller 500. Meanwhile, although not shown in the table, the multiple first patterns 101 may operate as touch receiving electrodes and the multiple third patterns 103 may operate as touch driving electrodes under the control of the controller 500.

[0321] One or two of the first to fourth patterns 101, 102, 103, and 104 may operate as a stylus driving electrode for driving the stylus pen by the control unit 500. A current loop for driving the stylus pen may be formed using one or two of the first to fourth patterns 101, 102, 103, and 104. The X-axis driving may be any one of the first patterns 101 and the second patterns 102, and the Y-axis driving may be any one of the third patterns 103 and the fourth patterns 104. The stylus pen may be driven by either the X-axis driving or the Y-axis driving, or both.

[0322] At least two of the first through fourth patterns 101, 102, 103, and 104 may operate as sensing electrodes for sensing a stylus pen signal emitted from a stylus pen. Since both X-axis sensing and Y-axis sensing are required to sense a stylus pen signal, two of the first through fourth patterns 101, 102, 103, and 104 are used. The X-axis sensing may be any one of the first patterns 101 and the second patterns 102, and the Y-axis sensing may be any one of the third patterns 103 and the fourth patterns 104.

[0323] In Table 2 above, "uplink signal magnitude" refers to the magnitude of a driving signal for driving a stylus pen. When the same stylus pen driving signal is applied to a number of first patterns 101 and a number of second patterns 102, and the magnitude of the signal received by the stylus pen is compared, the uplink signal is relatively larger when the stylus pen driving signal is applied to a number of second patterns 102 than when the stylus pen driving signal is applied to a number of first patterns 101.

[0324] This is because the other ends of the second patterns 102 are electrically connected to each other, and at least one current loop is formed if two or more second patterns to which a stylus pen driving signal is applied are appropriately selected, but the other ends of the first patterns 101 are not electrically connected to each other, and no current loop is formed. When a current flows through each first pattern 101, the RC of each first pattern 101 is charged, so the current cannot flow well from one end of each first pattern 101 to the other end. In addition, the stylus pen driving signal applied through the first patterns 101 is transferred to the second patterns 102 in which a current loop is formed through capacitive coupling, and at this time, the signal is attenuated due to the capacitive coupling.

[0325] Similarly, when the stylus pen driving signal is applied to a number of the fourth patterns 104, the uplink signal is relatively larger than when the stylus pen driving signal is applied to a number of the third patterns 103.

[0326] In Table 2 above, "downlink signal magnitude" refers to the magnitude of a stylus pen signal received from a stylus pen. When the same stylus pen signal is received through the multiple first patterns 101 and the multiple second patterns 102 and the signal magnitudes are compared, the downlink signal is relatively larger when the stylus pen signal is received through the multiple second patterns 102 than when the stylus pen signal is received through the multiple first patterns 101. This is because the multiple second patterns 102 are electrically connected at the other end to form a current loop, but the multiple first patterns 101 are not electrically connected at the other end, and in particular, the stylus pen signal is transmitted to the multiple first patterns 101 from the multiple second patterns 102 in which a current loop is formed through capacitive coupling, so that attenuation of the downlink signal occurs.

[0327] Similarly, when the stylus pen signals are received via multiple fourth patterns 104, the downlink signal is relatively larger than when the stylus pen signals are received via multiple third patterns 103.

[0328] In Table 2 above, "additional stylus channel" means whether an additional channel must be configured for a stylus pen in addition to touch sensing. If multiple second patterns 102 and / or multiple fourth patterns 104 are used for driving and sensing the stylus pen, an additional channel is required (shown as "Yes" in Table 2). On the other hand, if multiple first patterns 101 and / or multiple third patterns 103 for touch sensing are used for driving and sensing the stylus pen, an additional channel is not required (shown as "No" in Table 2).

[0329] Hereinafter, some examples of the various combinations (No. 1 to No. 32) in Table 2 above will be described in detail. Combinations not described here will be fully understood by those skilled in the art from the detailed description below.

[0330] In No. 1, the multiple first patterns 101 are used as touch driving electrodes for touch sensing of an object and also as stylus sensing electrodes for sensing a stylus pen signal. The multiple second patterns 102 are used as stylus driving electrodes for driving a stylus pen. The multiple third patterns 103 are used as touch sensing electrodes for touch sensing of an object and also as stylus sensing electrodes for sensing a stylus pen signal. And the multiple fourth patterns 104 are electrically floating.

[0331] In the case of No. 1, the magnitude of the uplink signal is relatively large because the multiple second patterns 102 are used as stylus driving electrodes. The magnitude of the downlink signal is relatively small because the multiple first patterns 101 and the multiple third patterns 103 are used as stylus sensing electrodes. Also, because the multiple second patterns 102 are used separately as stylus driving electrodes, a separate additional channel is required for driving the stylus pen, but an additional channel is not required for sensing the stylus pen.

[0332] In No. 4, the multiple first patterns 101 are used as touch driving electrodes for touch sensing of an object. The multiple second patterns 102 are used as stylus driving electrodes for driving a stylus pen and also as stylus sensing electrodes for sensing a stylus pen signal. The multiple third patterns 103 are used as touch sensing electrodes for touch sensing of an object. And the multiple fourth patterns 104 are used as stylus sensing electrodes for sensing a stylus pen signal.

[0333] In the case of No. 4, the magnitude of the uplink signal is relatively large because the multiple second patterns 102 are used as stylus driving electrodes. The magnitude of the downlink signal is relatively large because the multiple second patterns 102 and the multiple fourth patterns 104 are used as stylus sensing electrodes. In addition, because the multiple second patterns 102 are separately used as stylus driving electrodes and stylus sensing electrodes, and the multiple fourth patterns 104 are separately used as stylus sensing electrodes, additional channels are required for driving and sensing the stylus pen.

[0334] In No. 8, a number of first patterns 101 are used as touch driving electrodes for touch sensing of an object. A number of second patterns 102 are used as stylus sensing electrodes for sensing a stylus pen signal. A number of third patterns 103 are used as touch sensing electrodes for touch sensing of an object. And a number of fourth patterns 104 are used as stylus driving electrodes for driving a stylus pen and also as stylus sensing electrodes for sensing a stylus pen signal.

[0335] In the case of No. 8, the magnitude of the uplink signal is relatively large because the multiple fourth patterns 104 are used as stylus driving electrodes. The magnitude of the downlink signal is relatively large because the multiple second patterns 102 and the multiple fourth patterns 104 are used as stylus sensing electrodes. In addition, since the multiple second patterns 102 are separately used as stylus sensing electrodes and the multiple fourth patterns 104 are separately used as stylus driving electrodes and stylus sensing electrodes, additional channels are required for driving and sensing the stylus pen.

[0336] In No. 12, a number of first patterns 101 are used as touch driving electrodes for touch sensing of an object. A number of second patterns 102 are used as stylus driving electrodes for driving a stylus pen and as stylus sensing electrodes for sensing a stylus pen signal. A number of third patterns 103 are used as touch sensing electrodes for touch sensing of an object. And a number of fourth patterns 104 are used as stylus driving electrodes for driving a stylus pen and as stylus sensing electrodes for sensing a stylus pen signal.

[0337] In the case of No. 12, the magnitude of the uplink signal is relatively large because the multiple second and fourth patterns 102 and 104 are used as stylus driving electrodes. The magnitude of the downlink signal is relatively large because the multiple second patterns 102 and the multiple fourth patterns 104 are used as stylus sensing electrodes. In addition, because the multiple second patterns 102 are separately used as stylus driving electrodes and stylus sensing electrodes, and the multiple fourth patterns 104 are separately used as stylus driving electrodes and stylus sensing electrodes, additional channels are required for driving and sensing the stylus pen.

[0338] In No. 13, the multiple first patterns 101 are used as touch driving electrodes for touch sensing of an object, as stylus driving electrodes for driving a stylus pen, and as stylus sensing electrodes for sensing a stylus pen signal. The multiple third patterns 103 are used as touch sensing electrodes for touch sensing of an object, and as stylus sensing electrodes for sensing a stylus pen signal. And the multiple second and fourth patterns 102 and 104 are electrically floating.

[0339] In the case of No. 13, the magnitude of the uplink signal is relatively small because the multiple first patterns 101 are used as stylus driving electrodes. The magnitude of the downlink signal is relatively small because the multiple first patterns 101 and the multiple third patterns 103 are used as stylus sensing electrodes. In addition, since the multiple first patterns 101 are used as stylus driving electrodes and stylus sensing electrodes and the multiple third patterns 103 are used as stylus sensing electrodes, no additional channels are required for driving and sensing the stylus pen.

[0340] In No. 17, the multiple first patterns 101 are used as touch driving electrodes for touch sensing of an object and as stylus sensing electrodes for sensing a stylus pen signal. The multiple third patterns 103 are used as touch sensing electrodes for touch sensing of an object, as stylus driving electrodes for driving a stylus pen, and as stylus sensing electrodes for sensing a stylus pen signal. And the multiple second and fourth patterns 102 and 104 are electrically floating.

[0341] In the case of No. 17, since a number of third patterns 103 are used as stylus driving electrodes, the magnitude of the uplink signal is relatively small. Since a number of first patterns 101 and a number of third patterns 103 are used as stylus sensing electrodes, the magnitude of the downlink signal is relatively small. Furthermore, since a number of first patterns 101 are used as stylus sensing electrodes and a number of third patterns 103 are used as stylus driving electrodes and stylus sensing electrodes, a separate additional channel for driving and sensing the stylus pen is not required.

[0342] In No. 21, the multiple first patterns 101 are used as touch driving electrodes for touch sensing of an object, as stylus driving electrodes for driving a stylus pen, and as stylus sensing electrodes for sensing a stylus pen signal. The multiple third patterns 103 are used as touch sensing electrodes for touch sensing of an object, as stylus driving electrodes for driving a stylus pen, and as stylus sensing electrodes for sensing a stylus pen signal. And the multiple second and fourth patterns 102 and 104 are electrically floating.

[0343] In the case of No. 21, the magnitude of the uplink signal is relatively small because the multiple first and third patterns 101 and 103 are used as stylus driving electrodes. The magnitude of the downlink signal is relatively small because the multiple first patterns 101 and the multiple third patterns 103 are used as stylus sensing electrodes. In addition, since the multiple first patterns 101 are used as stylus driving electrodes and stylus sensing electrodes and the multiple third patterns 103 are used as stylus driving electrodes and stylus sensing electrodes, no additional channels are required for driving and sensing the stylus pen.

[0344] Among the various combinations (No. 1 to No. 32) in Table 2 above, Nos. 1, 5, 9, 25, and 29 are in the "stylus additional channel" column with "yes" for driving and "no" for sensing. Nos. 1, 5, 9, 25, and 29 use a number of first and third patterns 101, 103 to sense the stylus pen, and a number of second and / or fourth patterns 102, 104 to drive the stylus pen. Even if a number of second and / or fourth patterns 102, 104 are used when driving the stylus pen, it may be somewhat difficult to form a magnetic field for resonating the stylus pen, so that one end of two or more adjacent second patterns may be electrically connected. Similarly, one end of two or more adjacent fourth patterns may be electrically connected. This configuration has the advantage of reducing the number of additional channels for driving the stylus pen.

[0345] Figures 22 to 26 show some of the combinations in Table 2 above.

In addition, in the stylus sensing mode, the control unit 500 can detect the position of the stylus pen by detecting pen reception signals received from the plurality of first patterns 101 and the plurality of fourth patterns 104.

[0361] FIG. 27 is a schematic diagram of a touch input device according to another embodiment of the present invention.

[0362] Referring to FIG. 27, a touch input device according to another embodiment of the present invention includes a sensor unit 100' and a control unit 500'.

[0363] The sensor unit 100' includes a number of patterns. The number of patterns may include a pattern 1a 101a, a pattern 1b 101b, a pattern 2a 102a, a pattern 2b 102b, a third pattern 103, and a fourth pattern 104. Here, the third pattern 103 and the fourth pattern 104 have the same configuration as the third and fourth pattern units 103 and 104 of the sensor unit 100 shown in FIG. 16, and therefore a description thereof will be omitted.

[0364] The 1a pattern 101a has a shape extending along a first direction (or a major axis).

[0365] The 1a pattern 101a may include an inverted triangular pattern portion, a triangular pattern portion, and a connecting pattern portion connecting the inverted triangular pattern portion and the triangular pattern portion.

[0366] The 1a pattern 101a may have an opening in which the 2a pattern 102a is disposed.

[0367] The 1a pattern 101a may have a structure surrounding the 2a pattern 102a. The 1a pattern 101a is disposed at a predetermined distance from the 2a pattern 102a, and is electrically insulated therebetween.

[0368] The 2a pattern 102a is disposed adjacent to the 1a pattern 101a. For example, the 2a pattern 102a may be disposed inside the 1a pattern 101a.

[0369] The 2a pattern 102a may include an inverted triangular pattern portion, a triangular pattern portion, and a connecting pattern portion connecting the inverted triangular pattern portion and the triangular pattern portion.

[0370] Pattern 1b 101b has a shape extending along a first direction (or a long axis). Pattern 1b 101b may include an inverted triangular pattern portion, a triangular pattern portion, and a connecting pattern portion connecting the inverted triangular pattern portion and the triangular pattern portion. Pattern 1b 101b may have an opening in which pattern 2b 102b is disposed.

[0371] The pattern 1b 101b may have a structure surrounding the pattern 2b 102b. The pattern 1b 101b is disposed at a predetermined distance from the pattern 2b 102b, and is electrically insulated therebetween.

[0372] The pattern 2b 102b is disposed adjacent to the pattern 1b 101b. For example, the pattern 2b 102b is disposed inside the pattern 1b 101b.

[0373] Pattern 2b 102b may include an inverted triangular pattern portion, a triangular pattern portion, and a connecting pattern portion connecting between the inverted triangular pattern portion and the triangular pattern portion.

[0374] The plurality of 1a patterns 101a and the plurality of 1b patterns 101b are alternately arranged along a first direction, the plurality of 1a patterns 101a are electrically connected to each other, and the plurality of 1b patterns 101b are also electrically connected to each other.

[0375] Among the plurality of 1a patterns 101a, the 1a pattern 101a located at one end is electrically connected to the control unit 500'.

[0376] Among the plurality of 1b patterns 101b, the 1b pattern 101b located at one end is electrically connected to the control unit 500'.

[0377] The plurality of 2a patterns 102a and the plurality of 2b patterns 102b are alternately arranged along a first direction and are electrically connected to each other. Among the plurality of 2a patterns 102a and the plurality of 2b patterns 102b, the pattern 2b 102b located at one end may be electrically connected to the controller 500, and the pattern 2a 102a located at the other end may be electrically connected to another adjacent pattern 2a. Here, the pattern 2a 102a located at the other end and the other adjacent pattern 2a may be grounded.

[0378] The 1a pattern 101a, the 1b pattern 101b, the 2a pattern 102a, and the 2b pattern 102b may be disposed on the same layer. The 1a pattern 101a, the 1b pattern 101b, the 2a pattern 102a, and the 2b pattern 102b can be formed on the same layer using a metal mesh.

[0379] The control unit 500' has the same functions as the control unit 500 shown in FIG.

[0380] FIG. 28 illustrates a case where the touch input device illustrated in FIG. 27 operates in a touch sensing mode (or a 2D sensing mode).

[0381] 27 and 28, in a touch sensing mode, a controller 500′ may electrically connect a driving circuit unit for touch sensing to the third patterns 103 of a sensor unit 100′. One driving circuit unit may be electrically connected to each of the third patterns 103.

[0382] In addition, the control unit 500' can electrically connect a sensing circuit unit for touch sensing to the first and first patterns 101a and 101b of the sensor unit 100'.

[0383] In the touch sensing mode, the controller 500' applies driving signals for touch sensing to the plurality of third patterns 103 and receives sensing signals received from the plurality of 1a and 1b patterns 101a and 101b. The sensing circuit unit of the controller 500' electrically connected to the plurality of 1a and 1b patterns 101a and 101b can output capacitance change information included in the input sensing signals as a predetermined voltage value. The controller 500' can process the output voltage value to detect a touch position. Here, the controller 500' can cancel display noise and LGM noise by subtracting the sensing signal received from the 1b pattern 101b from the sensing signal received from the 1a pattern 101a.

[0384] Here, in order to prevent capacitive coupling between the third pattern 103 and the fourth pattern 104, the control unit 500' may control the same driving signal to be applied to the third patterns 103 and the fourth patterns 104. Alternatively, the control unit 500' may control the fourth patterns 104 to be applied with a reference potential.

[0385] FIG. 29 illustrates the touch input device illustrated in FIG. 27 operating in an antenna driving mode (or a stylus driving mode or a stylus uplink mode).

[0386] 27 and 29, in the antenna driving mode, the control unit 500' can electrically connect a driving circuit unit for driving the antenna to the second a and second b patterns 102a and 102b of the sensor unit 100'.

[0387] The control unit 500' can control the driving signals output from each driving circuit unit connected to the multiple 2a and 2b patterns 102a and 102b. For example, the control unit 500' can control the first driving circuit unit to output a pulse signal of a predetermined frequency, control the second driving circuit unit not to output any pulse signal, and control the third driving circuit unit to output a pulse signal opposite to the pulse signal output from the first driving circuit unit. In this case, a current loop is formed between the 2a and 2b patterns 102a and 102b electrically connected to the first driving circuit unit and the 2a and 2b patterns electrically connected to the third driving circuit unit. A magnetic field is generated by the formed current loop, and the magnetic field can resonate and drive a nearby stylus pen.

[0388] The control unit 500' may control any two driving circuits among a plurality of driving circuits electrically connected to a plurality of 2a and 2b patterns 102a and 102b to output opposite pulse signals. Therefore, the control unit 500' may change and set the size and position of the current loop in various ways. For example, when the control unit 500' detects the position of a nearby stylus pen, it may control the driving circuits electrically connected to two 2 patterns around the position of the stylus pen to output opposite pulse signals, and when the control unit 500' cannot detect the position of the stylus pen, it may control the driving circuits electrically connected to two 2a and 2b patterns 102a and 102b located at the outermost sides among the plurality of 2a and 2b patterns 102a and 102b to output opposite pulse signals.

[0389] Meanwhile, although not shown in a separate drawing, the controller 500′ may control the application of driving signals to a number of the 1a pattern 101a and the 1b pattern 101b, and / or the third pattern 103. In this case, there is an advantage that the total number of channels can be reduced.

[0390] FIG. 30 illustrates the touch input device illustrated in FIG. 27 operating in a stylus sensing mode (or a stylus downlink mode).

[0391] 30 and 27, in a stylus sensing mode, the control unit 500' can electrically connect a sensing circuit unit for stylus sensing to the 1a and 1b patterns 101a and 101b and the third pattern 103 of the sensor unit 100', respectively.

[0392] In the stylus sensing mode, in the same principle as described through Figure 21, when a stylus pen approaches any position of the sensor unit 100', a predetermined signal is output from the stylus pen, and an induced voltage is generated in 1a, 1b, 2a, 2b, 3rd and 4th patterns 101a, 101b, 102a, 102b, 103 and 104 due to the output signal.

[0393] Here, when the stylus pen is located far away from the control unit 500', the generation of the induced voltage causes almost no current to flow through the multiple 1a patterns 101a itself, but current flows in from the multiple 2a patterns 102a, so that the control unit 500' can detect the position of the stylus pen through a sensing circuit unit electrically connected to the multiple 1a patterns 101a. Here, the reason why the current flows in from the 2a pattern 102a to the 1a pattern 101a is because a potential difference of the induced voltage is generated between the 1a pattern 101a and the 2a pattern 102a, and the generated potential difference causes capacitive coupling between the 1a pattern 101a and the 2a pattern 102a.

[0394] Similarly, since almost no current flows through the multiple 1b patterns 101b themselves, but current flows in from the multiple 2b patterns 102b, the control unit 500' can detect the position of the stylus pen through a sensing circuit unit electrically connected to the multiple 1b patterns 101b.

[0395] Similarly, since almost no current flows through the third pattern 103 itself, but current flows in from the fourth pattern 104, the control unit 500' can detect the position of the stylus pen through the sensing circuit unit electrically connected to the third pattern 103.

[0396] Meanwhile, although not shown in the drawing, unlike FIG. 30, the control unit 500' can also electrically connect the sensing circuit unit to a number of 2a patterns 102a and 2b patterns 102b, and / or the fourth pattern 104, to detect the position of the stylus pen.

[0397] FIG. 31 is a schematic diagram of a touch input device according to yet another embodiment of the present invention.

[0398] The sensor unit 100'' of the touch input device shown in FIG. 31 has the same structure of patterns 1a, 1b, 2a, 2b, 3 and 4 as the sensor unit 100'' shown in FIG. 27. The difference is that the pattern 1b located on one side (lower side) of the multiple patterns 1b 101b electrically connected to each other along the first direction is electrically connected to the control unit 500'', and the pattern 1a 101a located on the other side (upper side) of the multiple patterns 1a 101a electrically connected to each other along the first direction is electrically connected to the control unit 500''. At this time, the pattern 1b located on the other side (upper side) of the multiple patterns 1b 101b electrically connected to each other along the first direction is electrically opened, and the pattern 1a 101a located on one side (lower side) of the multiple patterns 1a 101a electrically connected to each other along the first direction is electrically opened.

[0399] FIG. 32 illustrates a case where the touch input device illustrated in FIG. 31 operates in a touch sensing mode (or a 2D sensing mode).

[0400] The explanation of the touch sensing mode is the same as that explained in FIG. 28, so it will be omitted.

[0401] FIG. 33 illustrates the touch input device illustrated in FIG. 31 operating in an antenna driving mode (or a stylus driving mode or a stylus uplink mode).

[0402] The explanation of the antenna driving mode is the same as that explained in FIG. 29, so it will be omitted.

[0403] FIG. 34 illustrates the touch input device illustrated in FIG. 31 operating in a stylus sensing mode (or a stylus downlink mode).

[0404] The stylus sensing mode of FIG. 34 has differences compared to the stylus sensing mode of FIG.

[0405] When a stylus pen is brought close to any position on the sensor unit 100'' and then driven to emit a signal from the stylus pen, a predetermined signal is output from the stylus pen, and an induced voltage is generated in the 1a, 1b, 2a, 2b, 3rd and 4th patterns 101a, 101b, 102a, 102b, 103 and 104 due to the output signal.

[0406] Here, when the stylus pen is located far away from the control unit 500', the induced voltage causes almost no current to flow through the multiple 1b patterns 101b itself, but current flows from the multiple 2b patterns 102b as well as the multiple 1a patterns 101a, so that the control unit 500' can detect the position of the stylus pen through a sensing circuit unit electrically connected to the multiple 1b patterns 101b. Here, the reason why the current flows from the 2b pattern 102b and the 1a pattern 101a to the 1b pattern 101b is that a potential difference of the induced voltage is generated between the 1b pattern 101b and the 2b pattern 102b and between the 1b pattern 101b and the 1a pattern 101a, and the capacitive coupling between the 1b pattern 101b and the 2b pattern 102b due to the generated potential difference and the capacitive coupling between the 1b pattern 101b and the 1a pattern 101a.

[0407] Here, the reason why the current flows from the 1a pattern 101a to the 1b pattern 101b is that, unlike Fig. 30, a relatively large current flows through the multiple 1a patterns 101a themselves. This is because the direction of the conductive trace connected to the multiple 1a patterns 101a is connected in the opposite direction to the direction of the conductive trace connected to the multiple 1b patterns 101b. In other words, when the stylus pen is located far away from the sensing circuit unit connected to the multiple 1b patterns 101b, the stylus pen is located closer to the sensing circuit unit connected to the multiple 1a patterns 101a.

[0408] Similarly, since almost no current flows through the third pattern 103 itself, but current flows in from the fourth pattern 104, the control unit 500' can detect the position of the stylus pen through the sensing circuit unit electrically connected to the third pattern 103.

[0409] Meanwhile, although not shown in the drawing, unlike FIG. 34, the control unit 500'' can also detect the position of the stylus pen by electrically connecting the sensing circuit unit to a number of 2a patterns 102a, or 2b patterns 102b, or the fourth pattern 104.

[0410] FIG. 35 is a table comparing the properties of the various embodiments shown in FIGS.

[0411] 35, the embodiment of FIG. 16 can be configured with a total of 70 to 80 channels. Specifically, the driving electrodes TX used in the touch sensing mode can be configured with 20 channels, the receiving electrodes RX can be configured with 40 channels, and the antenna driving electrodes TX used in the antenna driving mode can be configured with 10 to 20 channels. Here, when the antenna driving mode is configured with 10 channels, this means that two adjacent channels are connected in parallel.

[0412] 16 may also be configured with 20 conductive traces on the left side and 20 traces on the right side along the second direction (short axis), thus allowing the width of the bezel of the touch input device to remain the same as before.

Specifically, the driving electrodes TX used in the touch sensing mode can be configured with 40 channels, the receiving electrodes RX can be configured with 40 channels, and the antenna driving electrodes TX used in the antenna driving mode can be configured with 10 to 20 channels. Here, when the antenna driving mode is configured with 10 channels, this means that two adjacent channels are connected in parallel.

[0414] 27 may also be configured with 20 conductive traces on the left side and 20 conductive traces on the right side along the second direction (short axis), thus allowing the width of the bezel of the touch input device to remain the same as before.

[0415] The embodiment of Fig. 31 can be configured with 90 to 100 channels in total. Specifically, the driving electrodes TX used in the touch sensing mode can be configured with 40 channels, the receiving electrodes RX can be configured with 40 channels, and the antenna driving electrodes TX used in the antenna driving mode can be configured with 10 to 20 channels. Here, when the antenna driving mode is configured with 10 channels, this means that two adjacent channels are connected in parallel.

[0416] Additionally, the embodiment of FIG. 31 may be configured with 30 conductive traces on the left side and 30 traces on the right side along the second direction (short axis).

[0417] FIG. 36 is a plan view of a portion of a sensor unit 200 according to another embodiment that can replace the sensor unit 100 in FIG.

[0418] 36, a sensor unit 200 according to another embodiment of the present invention includes a plurality of first patterns and a plurality of second patterns. Hereinafter, the plurality of first patterns will be described as a plurality of driving electrodes TX0, TX1, TX2, ..., and the plurality of second patterns will be described as a plurality of receiving electrodes RX0, RX1, RX2, .... Conversely, although not shown in the drawing, the plurality of first electrodes may be a plurality of receiving electrodes RX0, RX1, RX2, ..., and the plurality of second electrodes may be a plurality of driving electrodes TX0, TX1, TX2, ....

[0419] The multiple driving electrodes TX0, TX1, TX2, ... have a shape extending along a first direction (or horizontal direction), and the multiple receiving electrodes RX0, RX1, RX2, ... have a shape extending along a second direction (or vertical direction) perpendicular to the first direction.

[0420] A certain capacitance is formed between the driving electrodes TX0, TX1, TX2, ... and the receiving electrodes RX0, RX1, RX2, ..., particularly at their intersections. This capacitance changes when a touch input occurs at or around that point. Therefore, the presence or absence of a touch and the touch input can be detected by detecting the amount of change in capacitance from the signals output from the receiving electrodes RX0, RX1, RX2, ....

[0421] 36 includes a first driving pattern unit 211, a second driving pattern unit 213, and a connecting pattern unit 215. Here, the first driving pattern unit 211 may be named a 1-1 pattern unit, the second driving pattern unit 213 may be named a 1-2 pattern unit, and the connecting pattern unit 215 may be named a connecting pattern unit.

[0422] The first driving pattern unit 211 has a diamond or rhombus shape and has an opening O that is open inside. The opening O has a diamond or rhombus shape that corresponds to the outer shape of the first driving pattern unit 211. The opening O allows the first driving pattern unit 211 to have a diamond or rhombus strip shape. In the drawings, the first driving pattern unit 211 is shown in a diamond or rhombus shape, but this is merely an example and the first driving pattern unit 211 may have a shape such as a polygon or a rectangle.

[0423] The second drive pattern portion 213 is disposed within the opening O of the first drive pattern portion 211 .

[0424] The second drive pattern part 213 is disposed adjacent to the first drive pattern part 211. The second drive pattern part 213 may have a diamond shape or a rhombus shape. The external shape of the second drive pattern part 213 corresponds to that of the first drive pattern part 211. Unlike the first drive pattern part 211, the second drive pattern part 213 may not have an opening formed therein.

[0425] The first driving pattern unit 211 and the second driving pattern unit 213 are spaced apart from each other by a predetermined distance.

[0426] A plurality of first driving pattern units 211, each having a second driving pattern unit 213 disposed therein, are arranged along a first direction (or horizontal direction). A connection pattern 215 disposed between the plurality of first driving pattern units 211 electrically connects the plurality of first driving pattern units 211 to each other.

[0427] The connecting pattern 215 connects two adjacent first driving pattern units 211. One end of the connecting pattern 215 is connected to the first driving pattern unit 211 arranged on one side, and the other end of the connecting pattern 215 is connected to the first driving pattern unit 211 arranged on the other side. The connecting pattern 215 may be in a bar shape, but is not limited thereto, and may connect two adjacent first driving pattern units 211 in various shapes.

[0428] At least a part of the multiple first driving pattern units 211, at least a part of the multiple second driving pattern units 213, and at least a part of the multiple connection patterns 215 are arranged in the same layer. For example, the multiple first driving pattern units 211, the multiple second driving pattern units 213, and the multiple connection patterns 215 may be arranged together in the same layer. The multiple first driving pattern units 211, the multiple second driving pattern units 213, and the multiple connection patterns 215 may be formed of the same material. For example, the multiple first driving pattern units 211, the multiple second driving pattern units 213, and the multiple connection patterns 215 may be formed of a metal mesh. The metal mesh is patterned according to the shapes of the multiple first driving pattern units 211, the multiple second driving pattern units 213, and the multiple connection patterns 215, thereby forming the multiple driving electrodes TX0, TX1, TX2, ....

[0429] 36, the second drive pattern unit 213 is disposed in the opening O inside the first drive pattern unit 211, but the drive electrodes of the present invention are not limited thereto, and the first drive pattern unit 211 and the second drive pattern unit 213 may have other shapes other than a diamond or rhombus shape. The first drive pattern unit 211 and the second drive pattern unit 213 may be combined with each other in various shapes to form one drive electrode.

[0430] The second driving pattern units 213 of the driving electrodes TX0, TX1, and TX2 are electrically connected to each other. For example, the second driving pattern units 213 of the driving electrodes TX0, TX1, and TX2 may be electrically connected to each other through a bridge and a via.

[0431] The first driving pattern units 211 located at the other edge of each driving electrode TX0, TX1, TX2 are electrically open, and the second driving pattern units 213 located at the other edge of each driving electrode TX0, TX1, TX2 are electrically connected to each other. For example, the second driving pattern units 213 of each driving electrode TX0, TX1, TX2 may be electrically connected to each other through a bridge and a via. Here, the other side refers to the side of the first and second driving pattern units 211, 213 of each driving electrode TX0, TX1, TX2 that is farthest from the control unit 500 of FIG.

[0432] Each of the multiple receiving electrodes RX0, RX1, RX2 includes a first receiving pattern portion 231 and a second pattern portion 233. Here, the first receiving pattern portion 231 may be named a 2-1 pattern portion, and the second receiving pattern portion 233 may be named a 2-2 pattern portion.

[0433] The shapes of the first receiving pattern portion 231 and the second receiving pattern portion 233 are the same as those of the first driving pattern portion 211 and the second driving pattern portion 213, and therefore a detailed description thereof will be omitted.

[0434] A plurality of first receiving patterns 231 are arranged along a second direction (or a vertical direction). The plurality of first receiving patterns 231 are electrically connected to each other. For example, the plurality of first receiving patterns 231 may be electrically connected to each other through bridges and vias.

[0435] A plurality of second receiving pattern units 233 are arranged in the second direction (or the vertical direction) inside the first receiving pattern unit 231. The plurality of second receiving pattern units 233 are electrically connected to each other. For example, the plurality of second receiving pattern units 233 may be electrically connected to each other through bridges and vias.

[0436] The first receiving pattern parts 231 located at the other edge of the first receiving electrodes RX0, RX1, and RX2 are electrically open, and the second receiving pattern parts 233 located at the other edge of the second receiving electrodes 233 of the second receiving electrodes RX0, RX1, and RX2 are electrically connected to each other. For example, the second receiving pattern parts 233 may be electrically connected through a bridge and a via. Here, the other side refers to the side of the first and second receiving pattern parts 231 and 233 of the receiving electrodes RX0, RX1, and RX2 that is farthest from the control unit 500 of FIG.

[0437] At least a portion of the multiple first receiving pattern units 231 and at least a portion of the multiple second receiving pattern units 233 are arranged in the same layer. For example, the multiple first receiving pattern units 231 and the multiple second receiving pattern units 233 may be arranged together in the same layer. Here, the multiple first receiving pattern units 231 and the multiple second receiving pattern units 233 may be arranged together with the multiple first driving pattern units 211, the multiple second driving pattern units 213, and the multiple connecting patterns 215 in the same layer.

[0438] The multiple first receiving pattern parts 231 and the multiple second receiving pattern parts 233 may be formed of the same material. For example, the multiple first receiving pattern parts 231 and the multiple second receiving pattern parts 233 may be formed of a metal mesh. The metal mesh is patterned according to the shapes of the multiple first receiving pattern parts 231 and the multiple second receiving pattern parts 233, thereby forming the multiple receiving electrodes RX0, RX1, and RX2.

[0439] A bridge for electrically connecting the second driving pattern units 213 of each driving electrode TX0, TX1, TX2 and a bridge for electrically connecting the first and second receiving pattern units 231, 233 of each receiving electrode RX0, RX1, RX2 may be formed on a layer different from the layer on which the first and second driving pattern units 211, 213, the connecting pattern 215, and the first and second receiving pattern units 231, 233 are formed.

[0440] The sensor unit 200 shown in Fig. 36 may be driven in any one of a touch sensing mode, an antenna driving mode, and a stylus sensing mode, as shown in Figs. 17 to 21, under the control of the controller 500. In particular, in the touch sensing mode, the controller 500 controls so that a touch driving signal is applied to at least one of ATX1, ATX2, and ATX3, and may receive a touch receiving signal from at least one of ARX1, ARX2, and ARX3 to sense a touch position. In the antenna driving mode, the controller 500 may apply a pen driving signal to at least one of DTX1, DTX2, and DTX3, or may apply a pen driving signal to at least one of DRX1, DRX2, and DRX3. In the stylus sensing mode, the controller 500 may receive a pen receiving signal from at least one of ATX1, ATX2, and ATX3, and may sense a position of a stylus pen. Also, various combinations of Table 2 can be applied to the sensor unit 200 of Fig. 36. Therefore, the sensor unit 200 of Fig. 36 can be driven in any one of a touch sensing mode, an antenna driving mode, and a stylus sensing mode by the control unit 500 in various ways.

[0441] FIG. 37 is a plan view of a portion of a sensor unit 200' according to still another embodiment that can replace the sensor unit 100 of FIG.

[0442] The sensor unit 200' of Fig. 37 includes a number of driving electrodes TX0', TX1', TX2', ... and a number of receiving electrodes RX0, RX1, RX2, .... Here, the number of receiving electrodes RX0, RX1, RX2, ... are the same as the number of receiving electrodes RX0, RX1, RX2, ... shown in Fig. 36, and the number of driving electrodes TX0', TX1', TX2', ... are the same as the third and fourth patterns 103 and 104 shown in Fig. 16. Although not shown in the drawings, the opposite case is also possible.

[0443] Each of the plurality of driving electrodes TX0', TX1', TX2', ... may include a plurality of first driving pattern units and a plurality of second driving pattern units arranged along a horizontal direction, and may include a first connecting pattern unit connecting two adjacent pattern units among the plurality of first driving pattern units and a second connecting pattern unit connecting two adjacent pattern units among the plurality of second driving pattern units. One second connecting pattern unit may be arranged between two adjacent first connecting pattern units in a vertical direction.

[0444] The sensor unit 200' in Fig. 37 can further reduce the number of bridges and vias compared to the sensor unit 200 in Fig. 36. This is due to the shapes of the many drive electrodes TX0', TX1', TX2', ...

[0445] The sensor unit 200' shown in FIG. 37 is also controlled by the controller 500 as shown in FIG. 17 to FIG. 21, and can be driven in any one of a touch sensing mode, an antenna driving mode, and a stylus sensing mode. In particular, in the touch sensing mode, the controller 500 controls ATX1, ATX2, and ATX3 to apply touch driving signals, and can receive touch reception signals from ARX1, ARX2, and ARX3 to sense a touch position. In the antenna driving mode, the controller 500 can apply pen driving signals to DTX1, DTX2, and DTX3, or can apply pen driving signals to DRX1, DRX2, and DRX3. In the stylus sensing mode, the controller 500 can receive pen reception signals from ATX1, ATX2, and ATX3 and ARX1, ARX2, and ARX3 to sense a position of a stylus pen. Also, various combinations of Table 2 can be applied to the sensor unit 200' shown in FIG. 37. Therefore, the sensor unit 200' of FIG. 37 can be driven in any one of a touch sensing mode, an antenna driving mode, and a stylus sensing mode in various ways by the control unit 500 shown in FIG.

[0446] FIG. 38 shows a modification of the sensor unit shown in FIG.

[0447] Referring to FIG. 38, in the sensor unit 200'', the 1-1 pattern portions located at the first and / or second side ends among the multiple 1-1 pattern portions have a shape that is open in a first direction (or horizontal direction). Therefore, the 1-2 pattern portions located at the first and / or second side ends among the multiple 1-2 pattern portions may be exposed to the outside.

[0448] The 1-2 pattern portions located at the second end of the plurality of 1-2 pattern portions are electrically connected through a connection pattern without a via. Here, the connection pattern may be a conductive trace. Compared to FIG. 37, the 1-2 pattern portions located at the second end of the plurality of 1-2 pattern portions are advantageously arranged in the same layer as the connection pattern without being connected through a via.

[0449] In addition, in the sensor unit 200'', the 2-1 pattern portions located at the first and / or second side ends among the plurality of 2-1 pattern portions have a shape that is open in the second direction (or vertical direction). Therefore, the 2-2 pattern portions located at the first and / or second side ends among the plurality of 2-2 pattern portions may be exposed to the outside.

[0450] The 2-2 pattern portions located at the second end of the plurality of 2-2 pattern portions are electrically connected through a connection pattern without a via. Here, the connection pattern may be a conductive trace. Compared to FIG. 37, the 2-2 pattern portions located at the second end of the plurality of 2-2 pattern portions are advantageously arranged in the same layer as the connection pattern without being connected through a via.

[0451] The modification shown in FIG. 38 may be directly applied to the sensor portion shown in FIG.

[0452] The sensor unit 200'' shown in FIG. 38 may be controlled by the controller 500 as shown in FIG. 17 to FIG. 21 and may be driven in any one of a touch sensing mode, an antenna driving mode, and a stylus sensing mode. In particular, in the touch sensing mode, the controller 500 controls ATX1, ATX2, and ATX3 to apply touch driving signals and receives touch reception signals from ARX1, ARX2, and ARX3 to sense a touch position. In the antenna driving mode, the controller 500 may apply pen driving signals to DTX1, DTX2, and DTX3, or may apply pen driving signals to DRX1, DRX2, and DRX3. In the stylus sensing mode, the controller 500 may receive pen reception signals from ATX1, ATX2, and ATX3 and ARX1, ARX2, and ARX3 to sense a position of a stylus pen. Also, various combinations of Table 2 may be applied to the sensor unit 200' shown in FIG. 38. Therefore, the sensor unit 200'' of FIG. 38 can be driven in any one of a touch sensing mode, an antenna driving mode, and a stylus sensing mode in various ways by the control unit 500 shown in FIG.

[0453] FIG. 39 is a diagram showing another modified example of the sensor unit 100 shown in FIG.

[0454] 39, the structures of the main pattern portions of first to fourth pattern portions 101', 102', 103', and 104' are different from those in FIG.

[0455] In Figure 39, the outer contour of the second pattern portion 102' or the fourth pattern portion 104' is formed with a concave-convex structure, and the opening of the first pattern portion 101' or the fourth pattern portion 104' has a shape corresponding to the outer contour structure of the second pattern portion 102' or the fourth pattern portion 104'.

[0456] This structure has an advantage that the mutual capacitance Cm value between the first pattern unit 101' and the second pattern unit 102' in the same layer can be improved, and the mutual capacitance Cm value between the third pattern unit 103' and the fourth pattern unit 104' in the same layer can be improved. As the mutual capacitance Cm is improved, the voltage value output from the sensing circuit unit of the control unit 500 in the stylus sensing mode can be increased. Therefore, the stylus sensing sensitivity can be improved.

[0457] Here, the modification shown in FIG. 39 may be directly applied to the sensor units according to the various embodiments described above.

[0458] FIG. 40 shows yet another modified example of the sensor unit 100 shown in FIG.

[0459] The sensor unit 100 ″ shown in FIG. 40 further includes a number of fifth patterns 105 and a number of sixth patterns 106 compared to the sensor unit 100 shown in FIG.

[0460] The plurality of fifth patterns 105 are disposed in the same layer (second layer) as the plurality of first patterns 101, and are arranged in a plurality of rows along the first direction and the second direction.

[0461] Each of the fifth patterns 105 includes a shape that corresponds to and overlaps a part of a main pattern portion of the third pattern 103 arranged on another layer (1st layer). Also, the fifth pattern 105 is electrically connected to the fourth pattern 104 arranged on another layer (1st layer) through a via.

[0462] The fifth patterns 105 may form a mutual capacitance Cm in a vertical direction with the third patterns 103. Also, since the fifth pattern 105 is electrically connected to the fourth pattern 104 inside the third pattern 103, the third pattern 103 may form a mutual capacitance Cm not only with the fourth pattern 104 but also with the fifth pattern 105.

[0463] The plurality of sixth patterns 106 are disposed in the same layer (first layer) as the plurality of third patterns 103, and are arranged in a plurality of rows along the first and second directions.

[0464] Each sixth pattern 106 includes a shape that corresponds to and overlaps a part of a main pattern portion of a first pattern 101 disposed on another layer (second layer), and is electrically connected to a second pattern 102 disposed on another layer (second layer) through a via.

[0465] The sixth patterns 106 may form a mutual capacitance Cm in a vertical direction with the first patterns 101. In addition, since the sixth patterns 106 are electrically connected to the second patterns 102 inside the first patterns 101, the first patterns 101 may form a mutual capacitance Cm not only with the second patterns 102 but also with the sixth patterns 105.

[0466] 40 has an advantage that the first pattern 101 can form mutual capacitance in the vertical direction as well as the horizontal direction, and the third pattern 103 can form mutual capacitance in the vertical direction as well as the horizontal direction. Therefore, in the stylus sensing mode, the voltage value output from the sensing circuit unit of the control unit 500 can be increased, thereby improving the stylus sensing sensitivity.

[0467] Here, the modification shown in FIG. 40 may be directly applied to the sensor units according to the various embodiments described above.

[0468] FIG. 41 shows yet another modified example of the sensor unit 100 in FIG.

[0469] Compared to the sensor unit 100 shown in FIG. 16, the sensor unit 100''' shown in FIG. 41 has a portion of a second pattern 102' disposed on a different layer from the remaining portion. Specifically, the second pattern 102' includes a plurality of main pattern portions and a connecting pattern portion connecting two adjacent main pattern portions among the plurality of main pattern portions, but the plurality of main pattern portions of the second pattern 102' are disposed on a different layer from the plurality of connecting pattern portions of the second pattern 102'.

[0470] A large number of main pattern portions of second pattern 102' are arranged in the same layer as third pattern 103 and fourth pattern 104, and a large number of connecting pattern portions of second pattern 102' are arranged in the same layer as first pattern 101, as in FIG.

[0471] 16, the sensor unit 100''' shown in FIG. 41 may be driven in a touch sensing mode, an antenna driving mode, or a stylus pen sensing mode by the control unit 500. Also, various combinations of Table 2 can be applied to the sensor unit 100''' of FIG. 41. Therefore, the sensor unit 100''' of FIG. 41 can be driven in any one of the touch sensing mode, the antenna driving mode, and the stylus sensing mode in various manners by the control unit 500.

[0472] FIG. 42 shows yet another modified example of the sensor unit 100 in FIG.

[0473] Compared to sensor unit 100''' shown in FIG. 41, sensor unit 100'''' shown in FIG. 42 has a part of fourth pattern 104' arranged on a different layer from the remaining part. Specifically, fourth pattern 104' includes a plurality of main pattern portions and a connecting pattern portion connecting two adjacent main pattern portions among the plurality of main pattern portions, and the plurality of main pattern portions of fourth pattern 104' are arranged on a different layer from the plurality of connecting pattern portions of fourth pattern 104'. The plurality of main pattern portions of fourth pattern 104' are arranged on the same layer as first pattern 101, and the plurality of connecting pattern portions of fourth pattern 104' are arranged on the same layer as the plurality of main pattern portions of second pattern 102' and third pattern 103.

[0474] 42, first pattern 101, a number of connecting pattern portions of second pattern 102', and a number of main pattern portions of fourth pattern 104' are arranged on a first layer, and third pattern 103, a number of connecting pattern portions of fourth pattern 104', and a number of main pattern portions of second pattern 102' are arranged on a second layer. Here, the first layer and the second layer are different layers, and the positional relationship may be such that one is arranged on top of the other.

[0475] 16, the sensor unit 100'''' shown in FIG. 42 may be driven in a touch sensing mode, an antenna driving mode, or a stylus pen sensing mode by the control unit 500. Also, various combinations of Table 2 can be applied to the sensor unit 100'''' shown in FIG. 42. Therefore, the sensor unit 100'''' shown in FIG. 42 may be driven in any one of the touch sensing mode, the antenna driving mode, and the stylus sensing mode in various manners by the control unit 500.

[0476] FIG. 43 shows yet another modified example of the sensor unit 100 shown in FIG.

[0477] The sensor unit 100'''' shown in FIG. 43 is a modified version of the sensor unit 100'''' shown in FIG. 42. Compared to the sensor unit 100'''' shown in FIG. 42, the sensor unit 100'''''' shown in FIG. 43 has a different second pattern 102'' and a fourth pattern 104''.

[0478] Specifically, the second pattern 102'' includes a plurality of main pattern portions 102a'' and a plurality of connecting pattern portions 102b', and the size of the main pattern portion 102a'' is larger than that of the main pattern portion of the second pattern 102' of the sensor unit 100'''' shown in FIG. 42. The size and shape of the main pattern portion 102a'' may correspond to those of the main pattern portion of the first pattern 101.

[0479] In addition, the fourth pattern 104'' includes a plurality of main pattern portions 104a'' and a plurality of connecting pattern portions 104b', with the size of the main pattern portion 104a'' being larger than that of the fourth pattern 104' of the sensor unit 100'''' shown in FIG. 42. The size and shape of the main pattern portion 104a'' may correspond to those of the main pattern portion of the third pattern 103.

[0480] Since the main pattern portion 102a'' of the second pattern 102'' is larger than the main pattern portion of the second pattern 102' of Fig. 42, the corresponding area with the first pattern 101 is increased, thereby further improving the mutual capacitance Cm between the second pattern 102'' and the first pattern 101. Therefore, in the stylus sensing mode, the stylus sensing sensitivity can be further improved.

[0481] In addition, since the main pattern portion 104a'' of the fourth pattern 104'' is larger than the main pattern portion of the fourth pattern 104' of Fig. 42, the corresponding area with the third pattern 103 is increased, thereby further improving the mutual capacitance Cm between the fourth pattern 104'' and the third pattern 104. Therefore, in the stylus sensing mode, the stylus sensing sensitivity can be further improved.

[0482] FIG. 44 is a diagram showing a modification of the sensor unit 100 shown in FIG.

[0483] 44 differs from the sensor unit 100 shown in FIG. 16 in that the other ends of the plurality of second patterns 102 and the other ends of the plurality of fourth patterns 104 are electrically connected to each other.

[0484] In this configuration, when the sensor unit 100' is operated in a stylus sensing mode, one fourth pattern 104 is electrically connected to not only another fourth pattern but also a plurality of second patterns 102, which has the advantage of further reducing impedance.

[0485] 16, the sensor unit 100'''''' shown in FIG. 44 may be driven in a touch sensing mode, an antenna driving mode, or a stylus pen sensing mode by the control unit 500. Also, various combinations of Table 2 can be applied to the sensor unit 100'''''' shown in FIG. 44. Therefore, the sensor unit 100'''' shown in FIG. 44 can be driven in any one of the touch sensing mode, the antenna driving mode, and the stylus sensing mode by the control unit 500 in various manners.

[0486] FIG. 45 shows yet another modified example of the sensor unit 100 shown in FIG.

[0487] The sensor unit 100''''''' shown in Fig. 45 differs from the sensor unit 100 shown in Fig. 16 in that it has a second pattern 102' and a fourth pattern 104', further includes a plurality of fifth patterns 105' and a plurality of sixth patterns 106', and further includes a capacitor (cap) electrically connected to the fifth pattern 105' and the sixth pattern 106'. As the remaining configuration is the same, the other parts will be described in detail below.

[0488] The second pattern 102' may be a bar pattern disposed inside the first pattern 101 and extending in a second direction. Here, the second pattern 102' may have a certain width. The second pattern 102' is disposed in the same layer as the first pattern 101.

[0489] The fourth pattern 104' may be a bar pattern disposed inside the third pattern 103 and extending in a first direction. Here, the fourth pattern 104' may have a certain width. The fourth pattern 104' is disposed in the same layer (1st layer) as the third pattern 103.

[0490] The plurality of fifth patterns 105' are disposed in the same layer (second layer) as the plurality of first patterns 101, and are arranged in a plurality of rows along the first direction and the second direction. The plurality of fifth patterns 105' may be arranged between the plurality of first patterns 101.

[0491] Each of the fifth patterns 105' includes a shape that corresponds to and overlaps a main pattern portion of the third pattern 103 disposed on another layer (first layer). Also, the fifth pattern 105' is electrically connected to the fourth pattern 104' disposed on another layer (first layer) through a via.

[0492] The fifth pattern 105' electrically connected to one of the fourth patterns 104' among the plurality of fifth patterns 105' is arranged along the second direction. Here, a predetermined capacitor (cap) is connected to the fifth pattern 105' arranged at the other edge among the fifth patterns 105' arranged along the second direction. And, the capacitor (cap) may be grounded. Here, the fifth pattern 105' arranged at the other edge among the fifth patterns 105' arranged along the second direction means a pattern electrically connected farthest from the control unit 500 shown in FIG. 16. Although not shown in a separate drawing, the capacitor (cap) may be connected between the fifth pattern 105' and the ELVSS of the display panel (not shown). Also, the capacitor (cap) may have one end connected to the fifth pattern 105' and the other end connected to another layer (1st layer) in which the third pattern 103, the fourth pattern 104', and the sixth pattern 106' are arranged.

[0493] The fifth patterns 105' may form a mutual capacitance Cm in a vertical direction with the third patterns 103. Also, since the fifth pattern 105' is electrically connected to the fourth pattern 104' inside the third pattern 103, the third pattern 103 may form a mutual capacitance Cm not only with the fourth pattern 104' but also with the fifth pattern 105'.

[0494] The sixth patterns 106′ are disposed in the same layer as the third patterns 103, and are arranged in a plurality of layers along the first and second directions. The sixth patterns 106′ may be arranged in a plurality of layers between the third patterns 103.

[0495] Each sixth pattern 106' includes a shape that corresponds to and overlaps a main pattern portion of a first pattern 101 disposed on another layer (second layer), and is electrically connected to a second pattern 102' disposed on another layer (second layer) through a via.

[0496] The sixth pattern 106' electrically connected to one of the second patterns 102' among the sixth patterns 106' is arranged along the first direction. Here, a certain capacitor (cap) is connected to the sixth pattern 106' arranged at the other edge among the sixth patterns 106' arranged along the first direction. And, the capacitor (cap) may be grounded. Here, the sixth pattern 106' arranged at the other edge among the sixth patterns 106' arranged along the first direction means a pattern electrically connected farthest from the control unit 500 shown in FIG. 16. Although not shown in a separate drawing, the capacitor (cap) may be connected between the sixth pattern 106' and the ELVSS of the display panel (not shown). Also, the capacitor (cap) may have one end connected to the sixth pattern 106' and the other end connected to another layer (2nd layer) on which the first pattern 101, the second pattern 102', and the fifth pattern 105' are arranged.

[0497] The sixth patterns 106' may form a mutual capacitance Cm in a vertical direction with the first patterns 101. Also, since the sixth pattern 106' is electrically connected to the second pattern 102' inside the first pattern 101, the first pattern 101 may form a mutual capacitance Cm not only with the second pattern 102' but also with the sixth pattern 106'.

[0498] 45 has an advantage that the first pattern 101 can form mutual capacitance in the vertical direction as well as the horizontal direction, and the third pattern 103 can form mutual capacitance in the vertical direction as well as the horizontal direction. Therefore, in the stylus sensing mode, the voltage value output from the sensing circuit unit of the control unit 500 can be increased, thereby improving the stylus sensing sensitivity.

[0499] In addition, unlike the second pattern 102 and the fourth pattern 104 of the sensor unit 100 in Figure 16, the second pattern 102' and the fourth pattern 104' do not have a diamond-shaped main pattern portion, so when a display panel is positioned under the sensor unit 100'''''''', there is an advantage that visibility can be further improved compared to the sensor unit 100 in Figure 16.

[0500] 16, the sensor unit 100''''''' shown in FIG. 45 may be driven in a touch sensing mode, an antenna driving mode, or a stylus pen sensing mode by the control unit 500. Also, various combinations of Table 2 can be applied to the sensor unit 100'''''''' shown in FIG. 45. Therefore, the sensor unit 100''''''' shown in FIG. 45 can be driven in any one of the touch sensing mode, the antenna driving mode, and the stylus sensing mode in various manners by the control unit 500.

[0501] Meanwhile, although not shown in a separate drawing, without the fifth and sixth patterns 105' and 106', a capacitor (cap) may be electrically connected to the other ends of the second and fourth patterns 102 and 104. Furthermore, in the sensor units according to the various embodiments described above, the other ends of the second and fourth patterns (the other ends of the second driving pattern units 213 and the second receiving pattern units 233 in the case of FIGS. 36 and 37) may not be connected to each other, but a capacitor may be connected to each other end.

[0502] FIG 46 is yet another modified example of the sensor unit 100 shown in FIG 16. In the case of the sensor unit 100 of FIG 16, when the stylus pen 50 is located on the right edge (or the left edge) of the sensor unit 100, it may be difficult for the stylus pen 50 to provide a sufficient magnetic field signal, and a problem may occur in which the signal emitted from the stylus pen 50 cannot be large enough. To solve this problem, the sensor unit 100'''''''' shown in FIG 46 further includes a first trace t1 and a second trace t2 in addition to the sensor unit 100 shown in FIG 16.

[0503] The first trace t1 and the second trace t2 are directly connected to the conductive trace t0 that electrically connects the other ends of the multiple second patterns 102, and are arranged in a non-active area that is outside the active area tp (or touch area) of the touch input device. Here, at least a part of the conductive trace t0 may also be arranged outside the active area tp. The active area tp means an area that can be directly touched by an object, such as a finger or a stylus pen 50, and a non-active area is arranged around the active area tp. The non-active area may be, for example, a bezel area.

[0504] Specifically, the first trace t1 may be disposed in a non-active area outside the active area tp, with one end directly connected to the conductive trace t0 and the other end connected to the driving circuit unit of the control unit 500 via a switch sw in any one of a touch driving mode, a touch sensing mode, an antenna driving mode, and a stylus sensing mode.

[0505] The second trace t2 is disposed in a non-active area outside the active area tp, and one end may be directly connected to the conductive trace t0 and the other end may be connected to the drive circuit section of the control section 500 via a switch sw when in the antenna drive mode.

[0506] The first trace t1 may be disposed in a non-active area surrounding one of the left and right sides of the active area tp, and the second trace t2 may be disposed in a non-active area surrounding the other side of the active area tp.

[0507] The first trace t1 and the second trace t2 can provide a sufficient magnetic field signal to the stylus pen 50 even if the stylus pen 50 is located at one edge of the active area tp when the sensor unit 100'''''''' is driven in the same antenna driving mode as in FIG. 18. Therefore, in the touch input device including the sensor unit 100'''''''' shown in FIG. 46, the stylus pen 50 can receive a sufficient magnetic field signal and emit a sufficient signal regardless of where the stylus pen 50 is located in the active area tp.

[0508] Each of the first and second traces t1, t2 of the sensor unit 100'''''''' shown in FIG. 46 corresponds to one channel in FIG. 19, and the driving method such as (a) to (c) of FIG. 19 may be applied as is.

[0509] 16, the sensor unit 100'''''''' shown in FIG. 46 may be driven by the control unit 500 in a touch sensing mode, an antenna driving mode, or a stylus pen sensing mode.

[0510] Also, various combinations of Table 2 can be applied to the sensor unit 100'''''''' of FIG. 46. Therefore, the sensor unit 100'''''''' of FIG. 46 can be driven in any one of a touch sensing mode, an antenna driving mode, and a stylus sensing mode by the control unit 500 in various manners.

[0511] FIG. 47 is a diagram illustrating a first modified example of the fifth pattern 105 shown in FIG.

[0512] Referring to FIG. 47, the fifth pattern 105' is disposed on a layer different from the layer on which the third pattern 103 and the fourth pattern 104 are disposed.

[0513] The fifth pattern 105' may have a shape corresponding to the third pattern 103. For example, the fifth pattern 105' may have a diamond shape with a diamond-shaped opening therein.

[0514] A portion of the fifth pattern 105' may be arranged so as to overlap with the third pattern 103 in the vertical direction, and another portion may be arranged so as to overlap with the fourth pattern 104 in the vertical direction. For example, an outer edge portion of the fifth pattern 105' may be overlapped with an inner edge portion of the third pattern 103 arranged in another layer. An inner edge portion of the fifth pattern 105' may be overlapped with an outer edge portion of the fourth pattern 104 arranged in another layer.

[0515] The fifth pattern 105′ is electrically connected to the fourth pattern 104 arranged in another layer through conductive vias v. Here, the number of vias v may be multiple and may be arranged on the outer edge portion of the fourth pattern 104.

[0516] The fifth pattern 105' may form a mutual capacitance Cm in the vertical direction with the third pattern 103 disposed in another layer. Also, since the fifth pattern 105' is electrically connected to the fourth pattern 104 inside the third pattern 103 through the via v, the third pattern 103 may form a mutual capacitance Cc_tx not only with the fourth pattern 104 disposed in the same layer, but also with the fifth pattern 105' disposed in another layer.

[0517] Although not shown in a separate drawing, the sixth pattern 106 shown in FIG. 40 may have the same shape as the fifth pattern 105' shown in FIG. 47. In this case, the outer edge of the sixth pattern (not shown) may overlap with the inner edge of the first pattern 101 arranged in another layer, and the inner edge of the sixth pattern (not shown) may overlap with the outer edge of the second pattern 102 arranged in another layer. The sixth pattern (not shown) may be electrically connected to the second pattern 102 arranged in another layer through a conductive via. Similarly, such a sixth pattern (not shown) may also form a mutual capacitance in a vertical direction with the first pattern 101, and since the sixth pattern (not shown) is electrically connected to the second pattern 102 inside the first pattern 101, the first pattern 101 may eventually form a mutual capacitance Cm not only with the second pattern 102 but also with the sixth pattern (not shown).

[0518] 47 can form mutual capacitance not only in the horizontal direction but also in the vertical direction of the third pattern 103, and the sensor unit including the modified sixth pattern (not shown) can also form mutual capacitance not only in the horizontal direction but also in the vertical direction of the first pattern 101. Therefore, in the stylus sensing mode, the voltage value output from the sensing circuit unit of the controller of the control unit can be increased, thereby improving the stylus sensing sensitivity.

[0519] FIG. 48 is a modification of FIG.

[0520] FIG. 47 shows that the fifth pattern 105' is disposed below the third and fourth patterns 103, 104, whereas FIG. 37 shows that the fifth pattern 105' is disposed above the third and fourth patterns 103, 104.

[0521] The structure of the fifth pattern 105' shown in FIGS. 47 to 48 may be applied to the sensor units according to the various embodiments described above.

[0522] FIG. 49 is a diagram illustrating a modified example of the fifth pattern 105' shown in FIG.

[0523] 49, a fifth pattern 105'' has the same shape and position as the fifth pattern 105' shown in FIG. 47. The fifth pattern 105'' differs from the fifth pattern 105' shown in FIG. 47 in that the fifth pattern 105'' is electrically connected to the third pattern 103 arranged in another layer through a conductive via v. The via v is arranged at the inner edge portion of the third pattern 103.

[0524] Since the fifth pattern 105'' is electrically connected to the third pattern 103 arranged in another layer, the fourth pattern 104 can form a mutual capacitance Cc_Tx with the fifth pattern 105'' in the vertical direction.

[0525] The sensor unit including the modified fifth pattern 105'' shown in FIG. 49 also has an advantage in that mutual capacitance can be formed not only in the horizontal direction but also in the vertical direction.

[0526] FIG. 50 is a modified example of FIG.

[0527] FIG. 49 shows that the fifth pattern 105'' is disposed below the third and fourth patterns 103, 104, while FIG. 50 shows that the fifth pattern 105'' is disposed above the third and fourth patterns 103, 104.

[0528] The structure of the fifth pattern 105' shown in Figs. 49 and 50 may be applied to the sensor units according to the various embodiments described above.

[0529] 51 and 52 are diagrams for explaining modified examples of the third pattern 103 and the fourth pattern 104 in the sensor unit as shown in FIG. 41 or 42. In FIG.

[0530] 51 and 52, the third pattern 103 and the fourth pattern 104 according to the modified example are arranged on different layers, and a part of the third pattern 103 and a part of the fourth pattern 104 are arranged to overlap in the up-down direction (or vertical direction). For example, the inner edge portion of the third pattern 103 may be arranged to overlap in the vertical direction with the outer edge portion of the fourth pattern 104. In FIG. 51, the third pattern 103 is arranged above the fourth pattern 104, and in FIG. 52, the third pattern 103 is arranged below the fourth pattern 104.

[0531] The sensor unit including the third and fourth patterns 103 and 104 shown in Figures 51 and 52 may form a mutual capacitance Cc_Tx in a vertical direction rather than a horizontal direction. Although not shown in a separate drawing, the first and second patterns 101 and 102 shown in Figures 41 and 42 may also have the structure shown in Figures 51 and 52.

[0532] The modified structures shown in FIGS. 51 and 52 may be applied to the sensor portions according to the various embodiments described above.
