Description

Technical Field

[0001] This disclosure relates to input systems, and more specifically, to input systems including electronic devices, a ferrite core for a stylus, and a stylus including the same, wherein the electronic devices are capable of simultaneously sensing an object such as a finger approaching or touching from the outside and the stylus, and the ferrite core for the stylus is capable of amplifying the magnitude of the pen signal received from the electronic devices. Background Technology

[0002] Smartphones or tablets primarily feature touchscreens, allowing users to specify specific coordinates on the touchscreen using their fingers or styluses. Users can input specific signals on their smartphones by specifying these coordinates.

[0003] Previously, R-type touchscreens, which could simultaneously recognize a user's finger and a stylus, were widely used. However, R-type touchscreens suffer from reflections caused by the air layer between the ITO layers. Therefore, C-type touchscreens have recently become widely adopted. C-type touchscreens operate by sensing the capacitance difference between transparent electrodes that occurs when objects touch. However, a drawback of C-type touchscreens is that they have difficulty physically distinguishing between objects like fingers and styluses, leading to malfunctions due to accidental contact when the user uses a stylus.

[0004] To overcome this shortcoming, conventional methods have used additional software to distinguish between hands and styluses based on contact area, or, except for C-type touchscreens, EMR (Electro Magnetic Resonance) position measurement devices to differentiate between hands and styluses. The EMR method uses a magnetic field instead of an electric field as the driving force when using the stylus for touch functionality during touch and display operation, offering the advantage of being insensitive to display and external noise.

[0005] However, for the above-mentioned EMR method, in order to generate a magnetic field and transmit it to the stylus and then receive the magnetic field generated by the stylus, a sensor film made of an additional FPCB must be attached to the bottom of the display panel.

[0006] The sensor film is often referred to as a digitizer. The digitizer senses the change in the magnetic field caused by the interaction with the stylus as the stylus moves.

[0007] Figure 1 This is a diagram illustrating a foldable device as an example of an existing electronic device.

[0008] See Figure 1The foldable device has one or more internal screens and one or more external screens. The foldable device has an internal touchscreen 20 for the internal screens and an external touchscreen 25 for the external screens. Furthermore, digitizers 30 and 35 for driving and sensing the stylus 10 are disposed below the internal / external touchscreens 20 and 25.

[0009] As a passive stylus, the stylus 10 receives electromagnetic signals from digital converters 30 and 35 using a sensing resonance method, and the resonance signals emitted from the stylus 10 are received by digital converters 30 and 35.

[0010] In order to receive electromagnetic signals from the stylus 10, coils capable of inducing current through electromagnetic signals are closely arranged in the digitizers 30 and 35. As mentioned above, since the foldable device further has digitizers 30 and 35 in each internal / external touchscreen 20 and 25, there are limitations in the miniaturization and thinning of the entire device, and there is also the problem of difficulty in flexibly designing the internal structure.

[0011] Furthermore, since a magnetic field shielding material (not shown) and a copper layer (not shown) of a predetermined thickness are attached below the digital converters 30 and 35, there are further limitations in reducing the overall thickness of the device.

[0012] In particular, most currently popular foldable smartphones are designed with a foldable shape and have touchscreens 20 and 25 on both the outer and inner sides. However, only the inner touchscreen 20 on the inner side supports stylus functionality; the outer touchscreen 25 on the outer side does not. This is because, in order for the EMR-type stylus 10 to work, such as... Figure 4 As shown, digital converters 30 and 35 must be attached to the lower parts of the internal touchscreen 20 and the external touchscreen 25 respectively, which will increase the thickness and manufacturing cost of the entire device.

[0013] A stylus is a pen-shaped device that allows users to input data by gently touching the screen, such as by dragging or clicking. Users use styluses for precise touch input.

[0014] Styluses can be categorized into active styluses and passive styluses based on whether they contain a battery and electronic components.

[0015] However, recently, in order to realize a passive stylus that can accurately recognize touch, EMR (Electro Magnetic Resonance) and capacitive resonance technologies have been proposed as inductive resonance methods.

[0016] For EMR technology, the writing / drawing quality, which is the core function of the stylus, is superior. However, in addition to the capacitive touchpad, an additional EMR sensor panel and EMR driver IC are required, which results in a thicker and more expensive design.

[0017] The capacitive resonant method uses a general capacitive touch sensor and touch controller IC to improve the performance of the IC to further support pen touch without incurring additional costs.

[0018] In EMR or capacitive resonant methods, the amplitude of the resonant signal must be large to enable the touch sensor to accurately recognize stylus touches. Therefore, the frequency of the drive signal transmitted to the stylus must be almost identical to the resonant frequency of the resonant circuit built into the stylus. However, under existing EMR or capacitive resonant methods, even if the resonant frequency and the drive signal frequency match, signal transmission is difficult due to significant attenuation. As a result, despite extensive attempts by many touch controller IC suppliers, sufficient output signals have not been achieved, and no company has yet successfully achieved mass production.

[0019] Therefore, how to design the internal resonant circuit and the structure of the pen in order to manufacture an EMR or capacitive resonant stylus that can generate the maximum output signal has become a very important factor.

[0020] Figure 2 Figures (a) to (c) are used to illustrate a requirement of an existing stylus.

[0021] include Figure 2 The appearance design of existing styluses, including styluses 10a and 10b shown in (a) to (c), should take into account the user's environment and meet the predetermined requirements.

[0022] One requirement is that it must be able to draw while the existing styluses 10a, 10b are tilted at a predetermined angle (e.g., 60°) to the predetermined contact surface 31.

[0023] In particular, when some existing styluses 10a and 10b come into contact with the surface of the display panel 300 and a certain force F is applied, the pen tip is pressed and a portion of it enters the housing 19. Even when the pen tip is pressed and tilted at a predetermined angle (e.g., 60°), some styluses 10a and 10b should not have any problems with drawing.

[0024] As a result, when the existing styluses 10a and 10b are tilted relative to the contact surface 31, the tilt at a predetermined angle (e.g., 60°) should not be affected by the appearance device (e.g., housing 19) of the styluses 10a and 10b.

[0025] Figure 3 This is a diagram that briefly illustrates the internal structure of an existing stylus.

[0026] Figure 3 The existing styluses 10c and 10d shown consist of a pen tip 11, inductor sections 13 and 13', a capacitor section 15, and a housing 19. In addition to these, there are other additional components.

[0027] The inductor sections 13 and 13' are composed of ferrite cores 131 and 131' and a coil 133. The pen tip 11 has a structure in which a portion is inserted into a through hole in the ferrite cores 131 and 131'.

[0028] The inductor sections 13 and 13' and the capacitor section 15 are electrically connected to each other to form an LC resonant section. The LC resonant section is configured to resonate with a drive signal provided from the transmitter side located outside the stylus 10c and 10d, and emit a predetermined signal (hereinafter referred to as the pen signal) through resonance.

[0029] Figure 3 The shape of the ferrite core 131' of the inductor section 13' of the stylus 10d shown on the right is different from the shape of the ferrite core 131 of the inductor section 13 of the stylus 10c shown on the left. Specifically, the ferrite core 131' of the stylus 10d shown on the right has a shape that tapers towards the bottom (hereinafter referred to as a tapered shape). With the aforementioned tapered shape, the ferrite core 131' can be configured to be closer to the lower end side (or the tip side) of the housing 19 by a predetermined length H.

[0030] exist Figure 3 In the illustrated conventional styluses 10c and 10d, the magnitude of the pen signal received by the receiver located outside the styluses 10c and 10d may vary depending on the configuration of the inductor portions 13 and 13' within the housing 19. Preferably, the positions of the inductor portions 13 and 13' are determined to increase the magnitude of the pen signal.

[0031] because Figure 3 The ferrite core 131' of the stylus 10d shown on the right is configured closer to the pen tip than the ferrite core 131 of the stylus 10c shown on the left, thus the magnitude of the pen signal received at the receiver side is relatively larger. However, the conical shape of the ferrite core 131' of the stylus 10d shown on the right alone limits the ability to maximize the magnitude of the pen signal received at the receiver side.

[0032] Therefore, it is equally important to maximize the magnitude of the pen signal received by the receiver side while stably housing the inductor sections 13, 13' inside the housing 19.

[0033] On the other hand, styluses are used in various environments due to their nature, making them susceptible to damage from external factors. In particular, moisture ingress can significantly impact stylus functionality. Styluses contain delicate electronic components, and when water or moisture enters, it can cause corrosion or short circuits, thus reducing the stylus's performance. These issues can shorten the stylus's lifespan and cause inconvenience to users.

[0034] Currently, some styluses on the market are waterproof, but these often have imperfections or use expensive special materials, leading to high manufacturing costs. Therefore, there is a need to develop a technology that can prevent water from seeping into the stylus in a more effective and economical way. Summary of the Invention

[0177] The following detailed description of the invention refers to the accompanying drawings, which illustrate specific embodiments of the invention as examples. These embodiments are described in detail to enable those skilled in the art to practice the invention. It should be understood that the various embodiments of the invention, while different, are not mutually exclusive. For example, a particular shape, structure, and characteristic of one embodiment described herein may be implemented in other embodiments without departing from the spirit and scope of the invention. Furthermore, it should be understood that the position or arrangement of individual components within the various disclosed embodiments may be changed without departing from the spirit and scope of the invention. Therefore, the following detailed description is not intended to be limiting, and the scope of the invention, where appropriate, is limited to all scopes and claims identical to those of the protected technical solutions. Similar reference numerals in the drawings denote the same or similar functions in several respects.

[0178] Input systems according to various embodiments of this specification include electronic devices and styluses.

[0179] The electronic device according to various embodiments of this specification can be a general smartphone or an electronic device with a rectangular screen that is relatively larger than that of a general smartphone and has a diagonal length of about 10 inches to 13 inches. For example, it may include at least one of a foldable smartphone, a tablet computer, an in-vehicle display device, an e-book reader, a laptop computer, and a netbook computer.

[0180] Furthermore, the electronic device according to various embodiments of the present invention can not only detect the position of an object such as a finger on the screen, but also output a drive signal for driving a stylus, and sense the signal emitted from the stylus to detect the position of the stylus on the screen.

[0181] In addition, electronic devices according to various embodiments of the present invention include at least one foldable device with a foldable screen, which includes not only smartphones, but also tablet computers or laptops, etc.

[0182] The following detailed description of various embodiments is provided with reference to the accompanying drawings.

[0183] Figure 4 This is a simplified structural diagram of an electronic device according to a first embodiment of the present invention.

[0184] See Figure 4 The electronic device according to the first embodiment includes a sensor unit 10 and a touch controller 20, and includes multiple traces of two or more patterns electrically connected to the sensor unit 10 and the touch controller 20 or electrically connected to the sensor unit 10.

[0185] The sensor unit 10 is configured to be able to sense objects such as fingers and to drive and / or sense a stylus.

[0186] The sensor unit 10 includes multiple patterns (or multiple electrodes).

[0187] The sensor unit 10 may include a plurality of first patterns to fourth patterns 101, 102, 103, and 104.

[0188] The first pattern 101 has a shape extending along an arbitrary first direction X. The first direction may be the long axis direction of the display screen of the electronic device. The first pattern 101 may also be named TX (first touch electrode or touch driving electrode).

[0189] Each of the multiple first patterns 101 has one end electrically connected to the touch controller 20 via a trace, and the other end of each is electrically floating.

[0190] The second pattern 102 has a shape extending along the first direction X, is configured adjacent to the first pattern 101, and is configured at a predetermined interval from the first pattern 101. The second pattern 102 may also be named STX (stylus TX, first pen electrode, or pen drive electrode).

[0191] One end of the second pattern 102 is electrically connected to at least one other second pattern via a trace, and the other end is electrically connected to the touch controller 20 via a trace.

[0192] Of the plurality of second patterns 102, some of the second patterns may be configured with one end on the left and the other end on the right. Conversely, the remaining second patterns may be configured with one end on the right and the other end on the left.

[0193] The third pattern 103 has a shape extending along a second direction Y, which is different from the first direction. The second direction Y can be a direction perpendicular to the first direction X, or it can be the minor axis direction of the display screen of the electronic device. The third pattern 103 can also be named RX (second touch electrode or touch receiving electrode).

[0194] Each of the multiple third patterns 103 has one end electrically connected to the touch controller 20 via a trace, and the other end of each is electrically suspended.

[0195] The fourth pattern 104 has a shape extending along the second direction Y, is configured adjacent to the third pattern 103, and is configured at a predetermined interval from the third pattern 103. The fourth pattern 104 may also be named SRX (stylus RX, second pen electrode, or pen receiving electrode).

[0196] One end of each of the multiple fourth patterns 104 is electrically connected via at least one trace, and the other end can be electrically levitated.

[0197] The third pattern 103 and the fourth pattern 104 are disposed on the same layer or on a different layer from the first pattern 101 and the second pattern 102, and are disposed at a predetermined interval from the first pattern 101 and the second pattern 102.

[0198] Multiple first patterns 101 are arranged along the second direction Y, and multiple second patterns 102 are also arranged along the second direction Y. Multiple third patterns 103 are arranged along the first direction X, and multiple fourth patterns 104 are also arranged along the first direction X.

[0199] The first pattern 101 extends along a first direction X, and the third pattern 103 extends along a second direction Y. The first direction X is shorter than the second direction Y, therefore the number of multiple first patterns 101 is less than the number of multiple third patterns 103. Consequently, the number of channels in the multiple first patterns 101 is less than the number of channels in the multiple third patterns 103. The number of both the multiple first patterns 101 and the multiple third patterns 103 can be increased or decreased depending on the screen size of the electronic device.

[0200] As an example of an electronic device, the display screen of a tablet, laptop, or foldable device is in landscape orientation. Therefore, the number of channels (e.g., 8) of the multiple third patterns 103 is relatively greater than the number of channels (e.g., 5) of the multiple first patterns 101. Consequently, the multiple second patterns 102 used to drive and / or sense the stylus need to be arranged in an amount equivalent to the number of channels (five) of the multiple first patterns 101. In this case, the traces electrically connecting the multiple second patterns 102 and the controller 200 cause an increase in the total resistance of the sensor section 100. Therefore, parasitic capacitance can form between these traces. As an example, in the case of an 11-inch to 16-inch tablet, the increased number of channels of the second patterns 102 exceeds approximately 30, thus the parasitic capacitance becomes a significant burden on the electronic device.

[0201] The following figures illustrate in detail several implementations of an electronic device capable of solving this problem.

[0202] Figure 5 This is a simplified structural diagram of an electronic device according to a second embodiment of the present invention.

[0203] See Figure 5 The electronic device according to the second embodiment of the present invention includes a sensor unit 100 and a controller 200, and a plurality of traces electrically connecting the sensor unit 100 and the controller 200.

[0204] The sensor unit 100 includes a plurality of first patterns 101, a plurality of third patterns 103 and a plurality of fourth patterns 104, and the controller 200 includes a first circuit unit 210, a second circuit unit 220, a third circuit unit 230 and a control unit 240.

[0205] and Figure 4 Compared to the sensor unit 10 shown, Figure 5 The sensor unit 100 shown omits the second pattern 102. The two ends of the first pattern 101, arranged in the first direction (or the long axis direction), are electrically connected to the controller 200 via traces. More specifically, one end of the first pattern 101 is connected to the first circuit unit 210 of the controller 200 via a trace (or trace pattern), and the other end is connected to the second circuit unit 220 of the controller 200 via another trace (trace pattern). The method described above, where the two ends of each of the multiple first patterns 101 are electrically connected to the controller 200 via traces, is referred to as the 'doublerouting' method.

[0206] exist Figure 5 In the sensor unit 100, the first pattern 101 can be named a first pattern in the first direction X, the third pattern 103 can be named a first pattern in the second direction Y, and the fourth pattern 104 can be named a second pattern in the second direction Y. Alternatively, the first pattern 101 can be named the first pattern, the third pattern 103 can be named the second pattern, and the fourth pattern 104 can be named the third pattern. Hereinafter, for ease of explanation, we will directly use... Figure 4 The reference numerals used in the accompanying drawings are explained.

[0207] One end of the third pattern 103, which is arranged in the second direction (or the short axis direction), is closer to the controller 200 and is electrically connected to the controller 200 via a trace, while the other end is electrically suspended. One end of the third pattern 103 can be connected to the third circuit section 230 of the controller 200.

[0208] The end of the fourth pattern 104, which is adjacent to the third pattern 103 and arranged in the second direction (or the short axis direction), that is closer to the controller 200 is electrically levitated, while the other end is electrically connected to the other end of the other third pattern through one or more traces.

[0209] The first circuit section 210 and the second circuit section 220 of the controller 200 may include a touch driving circuit section that outputs a touch driving signal, a first driving circuit section that outputs a first driving signal, a first anti-driving circuit section that outputs a signal inverted from the first driving signal, a grounding circuit section, and a receiving circuit section that receives a pen signal. The third circuit section 230 may include a receiving circuit section that receives a touch sensing signal or receives a pen signal.

[0210] and Figure 4 Compared to the sensor unit 10 of the electronic device shown, the sensor unit 100 of the electronic device according to the second embodiment of the present invention does not have a plurality of second patterns 102, but can not only sense objects such as fingers, but also drive and / or sense a stylus. Furthermore, it can reduce the number of channels between the sensor unit 100 and the controller 200.

[0211] The electronic device according to the second embodiment of the present invention can be a landscape-type electronic device. The sensor unit 100 of the landscape-type electronic device is configured such that its width in the first direction is greater than its height in the second direction, and the controller 200 controlling the sensor unit 100 is disposed below the sensor unit 100. Landscape-type electronic devices, for example, correspond to the shape of a tablet computer or a foldable smartphone.

[0212] An electronic device according to a second embodiment of the present invention, including a sensor unit 100 and a controller 200, is not only capable of detecting the position of an object such as a finger on the screen of the electronic device, but also capable of driving a stylus to approach or contact the screen, and can detect the position of the stylus on the screen by sensing signals emitted from the stylus. See below. Figures 6 to 9 To provide a more detailed explanation.

[0213] Figure 6 It is used to explain the use of Figure 5 The diagram shows the first mode (or touch sensing mode) of an electronic device sensing an object. Figures 7 to 8 It is used to explain the use of Figure 5 The diagram shows the second mode (or uplink mode) of an electronic device driving a stylus. Figure 9 It is used to explain the use of Figure 5 The diagram shows the third mode (or downlink mode) of an electronic device sensing (or perceiving) a stylus.

[0214] According to a second embodiment of the present invention, the controller 200 of the electronic device can sense objects such as fingers that are close to or in contact with the sensor unit 100' using a plurality of first patterns 101 and a plurality of third patterns 103.

[0215] Specifically, see Figure 6The controller 200 can use a plurality of first patterns 101 of the sensor section 100 as touch driving electrodes TX to which touch driving signals are applied, and a plurality of third patterns 103 as touch receiving electrodes RX to which touch receiving signals are output. The reverse configuration is also acceptable.

[0216] The control unit 240 of the controller 200 can control the application of touch drive signals from the first circuit unit 210 and the second circuit unit 220 to the plurality of first patterns 101. For this purpose, the first circuit unit 210 and the second circuit unit 220 can each be configured to output touch drive signals according to the control signals from the control unit 240.

[0217] Through the control unit 240, the first circuit unit 210 can apply a touch drive signal to one end of a plurality of first patterns 101, and the second circuit unit 220 can simultaneously apply the touch drive signal to the other end of the plurality of first patterns 101. When the same touch drive signal is applied to both ends of each first pattern 101 at the same time, the position of the maximum resistance in each first pattern 101 can be the center of that first pattern 101.

[0218] The control unit 240 can receive touch sensing signals through multiple third patterns 103. Each received touch sensing signal includes information about the amount of capacitance change between the first pattern 101 and the third pattern 103. The control unit 240 can determine the position of the object based on the amount of capacitance change.

[0219] On the other hand, although not shown in another figure, the control unit 240 can control the application of touch drive signals to the first pattern 101 and the third pattern 103 respectively, and output touch sensing signals from the first pattern 101 and the third pattern 103 respectively.

[0220] According to a second embodiment of the present invention, the controller 200 of the electronic device can be formed by a plurality of first patterns 101 to form a current loop for driving a stylus.

[0221] Controller 200 can be used in the following ways Figure 7 and Figure 8 Either of the two methods described herein forms a current loop in the sensor section 100 for driving the stylus.

[0222] First, such as Figure 7The diagram illustrates a method where the controller 200 controls the flow of a preset current in one or more of a plurality of first patterns 101 in a first direction X, while simultaneously controlling the flow of the current in one or more other first patterns in a first reverse direction -X, which is the opposite direction to the first direction X. The controller 200 can select the one or more first patterns and the one or more other first patterns based on the position of the stylus 10 near or in contact with it. The first patterns(s) positioned above the stylus 10 can constitute the one or more first patterns, and the first patterns(s) positioned below the stylus 10 can constitute the one or more other first patterns.

[0223] The control unit 240 can control the application of a first driving signal to one end of one or more of the plurality of first patterns 101 via the first circuit unit 210, and control the application of a first reverse driving signal, which is an inverse signal of the first driving signal, to the other end of the plurality of first patterns via the second circuit unit 220, thereby causing current to flow in the plurality of first patterns in the first direction X. The first driving signal can be a pulse waveform signal or a sinusoidal waveform signal.

[0224] At the same time, the control unit 240 can control the application of a first reverse drive signal to one end of one or more other first patterns among the plurality of first patterns 101 through the first circuit unit 210, and control the application of a first drive signal to the other end of one or more other first patterns through the second circuit unit 220, thereby causing a first reverse direction -X current to flow in one or more other first patterns.

[0225] At least one current loop can be formed around the stylus 10 by a current flowing in a first direction X in one portion of the first pattern and a current flowing in a first opposite direction -X in another portion of the first pattern. The formed current loop generates a magnetic field, which can cause a resonant circuit provided inside the stylus 10 to resonate and drive the stylus 10.

[0226] Next, as Figure 8 As shown, the control unit 240 can control the application of a first drive signal to one end of a portion of the first patterns 101 through the first circuit unit 210, and control the grounding of the other end of the portion of the first patterns through the second circuit unit 220, thereby causing a current in the first direction X to flow in the portion of the first patterns.

[0227] Meanwhile, the control unit 240 can control the application of a first drive signal to one end of the remaining first pattern among the plurality of first patterns 101 through the first circuit unit 210, and control the grounding of the other end of the remaining first pattern through the second circuit unit 220, thereby causing current to flow in the remaining first pattern in the first reverse direction -X.

[0228] At least one current loop can be formed around the stylus 10 by the current flowing in the first direction X in a portion of the first pattern and the current flowing in the first opposite direction -X in the remaining first patterns. The current loop generates a magnetic field, which can drive the stylus 10 by resonating a resonant circuit provided inside the stylus 10.

[0229] According to the second embodiment of the present invention, the controller 200 of the electronic device can receive stylus signals (hereinafter referred to as pen signals) emitted from the stylus using a plurality of first patterns 101 and a plurality of third patterns 103, and determine the position of the stylus based on the received pen signals.

[0230] like Figure 9 As shown, multiple first patterns 101 and multiple third patterns 103 can be used to sense pen signals.

[0231] The control unit 240 can control the third circuit unit 230 to receive pen signals from the plurality of third patterns 103 respectively. The control unit 240 can determine the position of the stylus in the first direction X based on the pen signals received by the third circuit unit 230. The pen signals can be received through the plurality of third patterns 103 because the sensing signal sensed by the fourth pattern 104 is transmitted to the adjacent third pattern 103 through the capacitive coupling formed between the adjacent third patterns 103 and the fourth pattern 104.

[0232] Furthermore, the control unit 240 can control the first circuit unit 210 to ground one end of the plurality of first patterns 101, and can control the second circuit unit 220 to receive pen signals from the other end of each of the plurality of first patterns 101. The control unit 240 can determine the position of the stylus in the second direction Y based on the pen signals received by the second circuit unit 220.

[0233] exist Figure 9 In this configuration, the first circuit section 210 is configured to electrically ground one end of the plurality of first patterns 101, and the second circuit section 220 receives pen signals from the other end of the plurality of first patterns 101, but it can be configured in reverse.

[0234] Figure 10 It is used for explanation Figure 5 A diagram showing a modified example of the electronic device.

[0235] and Figure 5 Compared to the electronic devices shown, Figure 10 The two ends of each first pattern 101 of the sensor section 100 shown are electrically connected to each other through conductive traces and then connected to the controller 200'.

[0236] The controller 200' can use a first circuit section 210 to apply touch driving signals to a plurality of first patterns 101, and can use a third circuit section 230 to receive touch sensing signals from a plurality of third patterns 103.

[0237] On the other hand, although Figure 10 Not shown, but a multiplexer (not shown) can be configured between the sensor unit 100 and the controller 200'. The multiplexer (not shown) may include a switch that electrically connects or disconnects the two ends of each first pattern 101 according to a control signal. When the switch is turned on by the control signal, the two ends of each first pattern 101 are as follows: Figure 10 Electrically connected, the two ends of each first pattern 101 can be electrically disconnected from each other when the switch is turned off by the control signal.

[0238] Figure 11a It is used for explanation Figure 9 A diagram showing a modified example of the controller 200 of the electronic device.

[0239] See Figure 11a The controller 200' includes a third circuit section 230, a control section 240, and a differential amplifier 250.

[0240] Figure 11a The controller 200' shown is to Figure 9 The first circuit section 210 and the second circuit section 220 shown are replaced with a differential amplifier section 250.

[0241] like Figure 11a As shown, the third circuit section 230 receives stylus signals from a plurality of third patterns 103, and the control section 240 can determine the position of the stylus in the first direction X based on the signals detected by the third circuit section 230.

[0242] In addition, the differential amplification unit 250 receives stylus signals from both ends of each first pattern 101 and amplifies them differentially, and the control unit 240 can determine the position of the stylus in the second direction Y based on the differential signal output from the differential amplification unit 250.

[0243] Figure 11b It is used for explanation Figure 11a A diagram showing a modified example of the differential magnification section 250.

[0244] like Figure 11b As shown, the differential amplifier section 250' may include multiple differential amplifiers DP1, DPn, and DP1n. A pair of input terminals of the first differential amplifier DP1 are connected to the two ends of any one of the first patterns 101-1, respectively. A pair of input terminals of the second differential amplifier DPn are connected to the two ends of another first pattern 101-n, respectively. A pair of input terminals of the third differential amplifier DP1n are connected to the output terminals of the first differential amplifier DP1 and the second differential amplifier DPn, respectively. The output terminal of the third differential amplifier DPn1 is connected to... Figure 10 The control unit 240 of a is connected.

[0245] Among them, another first pattern 101-n can be adjacent to any first pattern 101-1.

[0246] Alternatively, another first pattern 101-n can be configured from any first pattern 101-1 at a predetermined interval. For example, one or more additional first patterns (not shown) can be configured between another first pattern 101-n and any first pattern 101-1.

[0247] Figure 12 It is used for explanation Figure 5 A diagram showing a modified example of the sensor section 100.

[0248] Figure 12 The sensor unit 100' shown also includes Figure 5 The sensor unit 100 shown includes multiple first patterns 101, multiple third patterns 103, and multiple fourth patterns 104, further comprising uplink channels UC1 and UC2. For reference, it should be noted that... Figure 12 Multiple first patterns 101, multiple third patterns 103, and multiple fourth patterns 104 are shown with lines, unlike... Figure 5 .

[0249] Multiple first patterns 101, multiple third patterns 103, and multiple fourth patterns 104 are configured in the active area (AA) of the display panel. Conversely, uplink channels UC1 and UC2 are configured in the dead space (or bezel) of the display panel.

[0250] Uplink channels UC1 and UC2 may each include an uplink trace configured in a first direction X, which is the same direction as the plurality of first patterns 101, and a pair of connecting traces connecting the two ends of the uplink trace and the pads (PAD). The uplink trace and the connecting traces may be integrally formed.

[0251] The uplink trace of the first uplink channel UC1 is configured on multiple first patterns 101, and the uplink trace of the second uplink channel UC2 can be configured below the multiple first patterns 101. Multiple first patterns 101 can be configured between the uplink trace of the first uplink channel UC1 and the uplink trace of the second uplink channel UC2.

[0252] exist Figure 5 In the sensor unit 100 shown, when the stylus 10 approaches or contacts the upper or lower edge region of the active region AA, it is difficult to form a current loop around the stylus 10 because there is no other pattern or trace for current to flow in the invalid space outside the active region AA.

[0253] And in Figure 12 In the sensor section 100' shown, uplink channels UC1 and UC2 are also arranged in the invalid space. Therefore, even if the stylus approaches or touches the upper or lower edge region of the active region AA, a predetermined current flows in the uplink channels UC1 and UC2, thereby forming a current loop around the stylus.

[0254] Figure 13 It is used for explanation Figure 12 A diagram showing a modified example of the sensor section 100'.

[0255] and Figure 12 Compared to the sensor section 100' shown, Figure 13 The sensor section 100'' shown differs in the second uplink channel UC2', but the rest of the configuration is the same.

[0256] The uplink trace of the second uplink channel UC2' can be formed as... Figure 12 The uplink trace of the second uplink channel UC2 shown is relatively longer.

[0257] The uplink trace of the second uplink channel UC2' can be formed to be relatively longer than the uplink trace of the first uplink channel UC1.

[0258] The connection trace of the second uplink channel UC2' may include a portion of parallel trace P' configured to be parallel to the uplink trace of the second uplink channel UC2'. In this case, it is preferable that the portion of parallel trace P' is configured as far away as possible from the connection trace of the second uplink channel UC2'. For example, it is preferable to configure a trace connected to one end of a plurality of first patterns 101 between the uplink trace of the second uplink channel UC2' and the portion of parallel trace P'. See also Figure 12 Explain your reasoning.

[0259] Figure 12 When a predetermined current flows in the second uplink channel UC2 of the sensor section 100' shown, the direction of the current flowing in the uplink trace of the second uplink channel UC2 is opposite to the direction of the current flowing in a part of the parallel trace P of the second uplink channel UC2, so a part of the magnetic field used to drive the stylus can be canceled out.

[0260] and Figure 13 The uplink trace of the second uplink channel UC2' in the sensor section 100'' shown is configured relatively further away from a portion of the parallel trace P', thus minimizing magnetic field cancellation.

[0261] Figure 14 This is a simplified structural diagram of an electronic device according to a third embodiment of the present invention.

[0262] See Figure 14 The electronic device according to the third embodiment of the present invention includes a sensor unit 100A and a controller 200A, and a plurality of traces electrically connecting the sensor unit 100A and the controller 200A.

[0263] The sensor unit 100A includes a plurality of first patterns 101 and a plurality of third patterns 103. Figure 5 Compared to the sensor unit 100 shown, Figure 14 The difference in the sensor unit 100A shown is that multiple fourth patterns 104 are omitted, and the two ends of each third pattern 103 are electrically connected to the controller 200A via traces. That is, Figure 14 The sensor unit 100A shown not only has multiple first patterns 101, but also multiple third patterns 103, which are directly connected to the controller 200A in a dual-route manner.

[0264] Controller 200A can be with Figure 5 The controller 200 shown similarly includes a first circuit section to a third circuit section 210, 220, 230 and a control section 240.

[0265] Figure 14 The electronic device shown is a landscape-type electronic device, and the number of the third pattern 103 can be more than the number of the first pattern 101.

[0266] Figure 14 The sensor unit 100A and controller 200A of the electronic device shown can not only detect the position of an object such as a finger on the display screen, but also drive a stylus to approach or touch the display screen, and can sense the signal emitted from the stylus to detect the position of the stylus on the display screen.

[0267] Specifically, such as Figure 6The controller 200A can control the application of touch drive signals to both ends of a plurality of first patterns 101 and determine the position of the object by receiving touch sensing signals through a plurality of third patterns 103.

[0268] like Figure 7 or Figure 8 The controller 200A can control the flow of current in a first direction X in a portion of the first pattern, which is distinguished by the position of the stylus, and the flow of current in the first opposite direction -X in another portion of the first pattern, thereby causing the resonant circuit of the stylus to resonate.

[0269] like Figure 9 The controller 200A can receive pen signals emitted from the stylus using multiple first patterns 101 and multiple third patterns 103, and determine the position of the stylus based on the received pen signals. Figure 14 The sensor unit 100A shown does not have multiple fourth patterns 104, therefore the controller 200A can control both ends of multiple third patterns 103 to receive pen signals in the same way as both ends of multiple first patterns 101. That is, Figure 14 The sensor unit 100A shown can be omitted from use. Figure 9 Instead of the capacitive coupling method described in the diagram, the pen signal is received directly through the third pattern 103.

[0270] Although no additional diagram is used, it can be seen that... Figure 12 or Figure 13 The uplink channels UC1 and UC2 shown are directly applicable to Figure 14 The sensor unit 100A shown is shown.

[0271] exist Figure 14 In the illustrated electronic device, each of the first patterns 101 is connected to the controller 200A in a dual-route manner, therefore the controller 200A is... Figure 9 When the pen signal is driven in the third mode (or downlink mode) shown, the pen signal output through the first pattern 101 can be directly received by the controller 200A. Similarly, since each third pattern 103 is connected to the controller 200A in a dual-route manner, when the controller 200A is driven in the third mode (or downlink mode), the pen signal output through the third pattern 103 can be directly received by the controller 200A.

[0272] Figure 15 It is a brief illustration Figure 4 A diagram showing a modified example of the sensor section 10.

[0273] like Figure 15 As shown, the sensor unit 10' includes a first pattern to a fourth pattern 101, 102, 103, 104.

[0274] Figure 15 Of the plurality of first patterns 101 in the sensor section 10', one end (left end) of the upper half of the first pattern 101 located with reference to the second direction Y is connected to a trace 101cl for connection with a touch controller (not shown), and the other end (right end) is suspended. The other end (right end) of the remaining half of the first pattern 101 located with reference to the second direction Y is connected to a trace 101cr for connection with a touch controller (not shown), and one end (left end) is suspended.

[0275] Figure 15 In the sensor section 10', the right ends of the upper half of the plurality of second patterns 102, with reference to the second direction Y, are electrically connected to each other via trace 102cr, while the left ends are suspended. Similarly, the left ends of the lower half of the plurality of second patterns 102, with reference to the second direction Y, are electrically connected to each other via trace 102cl, while the right ends are suspended.

[0276] Figure 15 The lower end of the multiple third patterns 103 of the sensor section 10' is connected to the touch controller (not shown) via traces, while the upper end is floating.

[0277] Figure 15 The upper ends of the plurality of fourth patterns 104 of the sensor section 10' are electrically connected to each other via traces 104c. The lower ends of the plurality of fourth patterns 104 can be connected in parallel in pairs to connect to a touch controller (not shown). This part differs from... Figure 4 Sensor section 10.

[0278] The touch controller (not shown) can enable multiple first patterns 101 and multiple third patterns 103 to operate in a first mode (touch sensing mode) for sensing objects such as fingers.

[0279] The touch controller (not shown) can enable multiple fourth patterns 104 to operate in a second mode (uplink mode) for driving the stylus.

[0280] The touch controller (not shown) enables multiple first patterns 101 and multiple third patterns 103 to operate in a third mode (downlink mode) for sensing a stylus. In this mode, pen signals output from the multiple first patterns 101 can be transmitted from multiple second patterns 102 via capacitive coupling, and pen signals output from the multiple third patterns 103 can be transmitted from multiple fourth patterns 104 via capacitive coupling.

[0281] and Figure 4 Compared to the sensor unit 10 shown, Figure 15The sensor section 10' shown has the advantage of reducing the number of channels (or pins) in the touch controller (not shown). This is because the lower ends of multiple fourth patterns 104 are connected in parallel in pairs. For example, if there are 35 first patterns 101 and second patterns 102, and 42 third patterns 103 and fourth patterns 104, the touch controller (not shown) would require 35 pins connected to the 35 first patterns 101, 42 pins connected to the 42 third patterns 103, and 21 pins connected to the 42 fourth patterns 104. 1 / 2) pins. As a result, the touch controller (not shown) requires a total of 98 pins. And... Figure 4 In the case of the sensor section 10, the lower ends of the fourth pattern 104 are not connected in parallel with each other in pairs, so the touch controller 20 also needs 21 pins for the fourth pattern 104.

[0282] If used Figure 15 The sensor unit 10' shown can reduce the number of channels in the touch controller (not shown), thus having the advantage of reducing the size and manufacturing cost of the touch controller (not shown).

[0283] In addition, Figure 15 In the sensor unit 10' shown, the left end of a portion of the first patterns 101 arranged on the upper side with reference to the second direction Y is connected to a touch controller (not shown), and the right end of the remaining first patterns arranged on the lower side is connected to the touch controller (not shown). With this configuration, the number of traces arranged in the side ring areas of the display panel can be reduced.

[0284] On the other hand, Figure 15 In the sensor unit 10' shown, the lowermost first pattern 101lb of the portion of first patterns 101 connected to the touch controller (not shown) on the left end and the uppermost first pattern 101ru of the remaining first patterns connected to the touch controller (not shown) on the right end are connected to the trace in opposite directions instead of in the same direction. Therefore, if the touch controller (not shown) differentially outputs signals from the lowermost first pattern 101lb and the uppermost first pattern 101ru, there is a problem of distortion in the output differential signals. This is also known as 'half-distortion'. This half-distortion can cause unwanted ghost touches by the user.

[0285] Figure 16 It is a brief illustration Figure 15 A diagram showing a modified example of the sensor section 10'.

[0286] like Figure 16 As shown, the sensor unit 10'' includes a first pattern to a fourth pattern 101, 102, 103, and 104.

[0287] and Figure 15 Compared to the sensor section 10' shown, Figure 16 The sensor section 10'' is connected to the touch controller (not shown) via trace 101cl at all left ends of the plurality of first patterns 101, and differs in that all right ends of the plurality of second patterns 102 are electrically connected to each other via trace 102cr. This difference allows for differential connection even between the touch controller (not shown). Figure 16 The signal output by the multiple first patterns 101 of the sensor section 10'' does not suffer from the aforementioned semi-distortion.

[0288] The touch controller (not shown) can enable multiple first patterns 101 and multiple third patterns 103 to operate in a first mode (touch sensing mode) for sensing objects such as fingers.

[0289] The touch controller (not shown) can enable multiple fourth patterns 104 to operate in a second mode (uplink mode) for driving the stylus.

[0290] The touch controller (not shown) enables multiple first patterns 101 and multiple third patterns 103 to operate in a third mode (downlink mode) for sensing a stylus. In this mode, pen signals output from the multiple first patterns 101 can be transmitted from multiple second patterns 102 via capacitive coupling, and pen signals output from the multiple third patterns 103 can be transmitted from multiple fourth patterns 104 via capacitive coupling.

[0291] Figure 16 The number of channels of the touch controller (not shown) for the 10'' sensor section and Figure 15 The number of channels is the same as that of the touch controller (not shown) used for the sensor section 10'.

[0292] on the other hand, Figure 16 In the sensor section 10'', all left ends of the plurality of first patterns 101 are connected to the touch controller (not shown) via traces 101cl. Therefore, the number of traces 101cl arranged in the left seat area increases relatively, thus the seat can become relatively thicker. In addition, the traces 101cl cause the resistance to increase relatively, which can lead to a narrowing of the touch bandwidth.

[0293] Figure 17 It is a brief illustration Figure 16 A diagram showing a modified example of the sensor section 10''.

[0294] like Figure 17 As shown, the sensor unit 10''' includes first to fourth patterns 101, 102, 103, and 104.

[0295] and Figure 16 Compared to the sensor section 10'' shown, Figure 17 The sensor section 10''' differs in that it is not connected in parallel with each other in pairs at the lower end of the plurality of fourth patterns 104, but is connected individually to the touch controller (not shown).

[0296] Figure 17 The sensor unit 10''' can directly use multiple fourth patterns 104 to sense pen signals emitted from the stylus.

[0297] Figure 17 The sensor section 10''' image Figure 16 Like the sensor section 10'', traces 101cl are connected to the left end of multiple first patterns 101, so no half-distortion occurs.

[0298] in addition, Figure 17 The sensor section 10''' can directly sense the pen signal emitted from the stylus using multiple fourth patterns 104, thus avoiding the use of capacitive coupling (Cc) between adjacent third patterns 103 and fourth patterns 104. Therefore, the capacitance value of the sensor section 10''' is reduced, allowing for a more efficient sensing experience compared to traditional styluses. Figure 16 The sensor section 10'' has a relatively larger touch bandwidth.

[0299] On the other hand, used for Figure 17 The number of channels (or pins) of the 10''' touch controller (not shown) of the sensor section is higher than that used for... Figure 16 The touch controller (not shown) of the sensor section 10'' has more channels. This is because multiple fourth patterns 104 are connected to the touch controller (not shown) respectively.

[0300] Figure 18 It is a brief illustration Figure 16 A diagram showing another variation of the sensor section 10''.

[0301] like Figure 18 As shown, the sensor unit 10'''' includes first to fourth patterns 101, 102, 103, and 104.

[0302] and Figure 16 Compared to the sensor section 10'' shown, Figure 18The sensor section 10'''' differs in that it is electrically connected to the touch controller (not shown) via traces 101cl and 101cr not only on the left side of the plurality of first patterns 101, but also on the right side, through a dual-routing method. This difference results in a higher touch bandwidth compared to... Figure 16 The 10'' sensor section has the advantage of being more expanded.

[0303] in addition, Figure 18 The sensor section 10'''' image Figure 16 The sensor section 10'' does not experience half-distortion.

[0304] On the other hand, used for Figure 18 The number of channels (or pins) of the 10''''' touch controller (not shown) of the sensor section is higher than that used for Figure 16 The touch controller (not shown) of the sensor section 10'' has more channels. This is because multiple first patterns 101 are connected to the touch controller (not shown) in a dual-route manner.

[0305] Figure 19 It is a brief illustration Figure 15 A diagram showing another variation of the sensor section 10'.

[0306] like Figure 19 As shown, the sensor unit 10''''' includes first to fourth patterns 101, 102, 103, and 104.

[0307] Figure 19 The sensor section 10''''' with Figure 15 Compared to the sensor section 10', there are differences in the plurality of first patterns 101 and the plurality of second patterns 102.

[0308] The plurality of first patterns 101 include a portion of a first pattern connected to a side trace 101cl' for connection with a touch controller (not shown) and another portion of a first pattern connected to a side trace 101cr'. The portion of the first pattern and the other portion of the first pattern are arranged alternately one after another along a second direction Y.

[0309] The plurality of second patterns 102 also include a portion of the second pattern connected to one side trace 102cl for connection with a touch controller (not shown) and another portion of the second pattern connected to the other side trace 102cr. The portion of the second pattern and the other portion of the second pattern are arranged alternately one after another along the second direction Y.

[0310] When any one of the multiple first patterns 101 is connected to the trace 101cl' at both ends, any one of the multiple second patterns 102 that is adjacent to any one of the first patterns 101 can be connected to the trace 102cr at both ends.

[0311] connect Figure 19 The multiple first patterns 101 of the sensor section 10''''' shown and the traces 101cl', 101cr' of the touch controller (not shown) are alternately arranged on the left side and on the right side along the second direction Y. Therefore, the number of traces arranged on the left and right sides is the same or similar, thus having the advantage of being able to maintain uniformity.

[0312] A touch controller (not shown) can be used Figure 19 The sensor unit 10 shown can sense (first mode) the touch of an object such as a finger, drive (second mode) a stylus, and sense (third mode) a pen signal from the stylus. See Table 1 below for details on how the touch controller (not shown) drives the sensor unit 10 in each mode.

[0313] Table 1

[0314]

[0315] See also Figure 19 According to Table 1, the touch controller (not shown) can enable the sensor unit 10 to operate in the first mode (Touch).

[0316] As an example of the first mode (Touch), the touch controller (not shown) can apply a touch drive signal to at least one of the plurality of first patterns 101 of the sensor section 10'''''' and receive touch sensing signals from the plurality of third patterns 103. The touch controller (not shown) can differentially process the touch sensing signals received from the plurality of third patterns 103.

[0317] As another example of the first mode (Touch), the touch controller (not shown) can apply a touch drive signal to at least one of the plurality of third patterns 103 of the sensor unit 10''''''' and receive touch sensing signals from the plurality of first patterns 101. The touch controller (not shown) can differentially analyze the touch sensing signals received from the plurality of first patterns 101. In the case of differentially analyzing the touch sensing signals, to prevent the aforementioned 'half-distortion' from occurring, the touch controller (not shown) can differentially analyze the touch sensing signals output from the Nth first pattern 101 and the (N+2)th first pattern 101n from the top of the plurality of first patterns 101.

[0318] The touch controller (not shown) can enable the sensor unit 10''''' to operate in a second mode (Stylus / Drive). As an example, the touch controller (not shown) can apply a pen drive signal to at least one of the plurality of fourth patterns 104 of the sensor unit 10''''''.

[0319] The touch controller (not shown) enables the sensor unit 10 to operate in a third mode (stylus / receiver).

[0320] As an example of the third mode (stylus / receiver), the touch controller (not shown) can receive pen sensing signals from a plurality of first patterns 101 and a plurality of third patterns 103 of the sensor unit 10''''''. The pen sensing signals output from each first pattern 101 are transmitted via capacitive coupling from a second pattern 102 adjacent to that first pattern 101. The pen sensing signals output from each third pattern 103 are transmitted via capacitive coupling from a fourth pattern 104 adjacent to that third pattern 103. The touch controller (not shown) can differentially receive the pen sensing signals from the plurality of first patterns 101 (or the plurality of third patterns 103). In the case of differentially receiving pen sensing signals, to prevent the aforementioned 'half-distortion', the touch controller (not shown) can differentially receive the pen sensing signals output from the Nth first pattern 101 and the (N+2)th first pattern 101n from the top of the plurality of first patterns 101.

[0321] As another example of the third mode (stylus / receiver), the touch controller (not shown) can receive pen sensing signals from a plurality of first patterns 101 and a plurality of fourth patterns 104 of the sensor unit 10''''''. The pen sensing signals output from each first pattern 101 are transmitted via capacitive coupling from a second pattern 102 adjacent to that first pattern 101. The pen sensing signals output from the plurality of fourth patterns 104 are signals directly sensed from the pen signal of an external stylus, and are not signals transmitted via capacitive coupling. The touch controller (not shown) can differentially receive the pen sensing signals from the plurality of first patterns 101 (or the plurality of fourth patterns 104). In the case of differentially receiving pen sensing signals, to prevent the aforementioned 'half-distortion', the touch controller (not shown) can differentially receive the pen sensing signals output from the Nth first pattern 101 and the (N+2)th first pattern 101n from the top of the plurality of first patterns 101.

[0322] Although not shown in another diagram, Figure 19 When one electrically levitated end of the plurality of second patterns 102 of the sensor unit 10''''' shown is electrically connected to a touch controller (not shown), the touch controller (not shown) can enable this sensor unit (not shown) to operate in a third mode (stylus / receiver). In the third mode, the controller (not shown) can receive pen sensing signals from the plurality of second patterns (not shown) and the plurality of third patterns 103 of the sensor unit (not shown), and can also receive pen sensing signals from the plurality of second patterns (not shown) and the plurality of fourth patterns 104.

[0323] Figure 20 It is a brief illustration Figure 19 A diagram showing a modified example of the sensor section 10'''''.

[0324] like Figure 20 As shown, the sensor unit 10'''''' includes first to fourth patterns 101, 102, 103', and 104.

[0325] and Figure 19 Compared to the 10''''' sensor section, Figure 20 The sensor section 10'''''' differs in several third patterns 103'.

[0326] Each of the multiple third patterns 103' includes a third-1 pattern 103-1 and a third-2 pattern 103-2 arranged adjacent to each other.

[0327] Pattern 103-1 of pattern 3-1 includes a plurality of main pattern portions 103-1a arranged along the second direction Y and a connecting pattern portion 103-1c of two adjacent main pattern portions 103-1a among the plurality of main pattern portions 103-1a. Each main pattern portion 103-1a of pattern 3-1 may have a quadrilateral, rhombus or diamond shape, and may have an opening that allows each main pattern portion 103-2a of pattern 3-2 to be arranged inside.

[0328] Pattern 103-2 (3-2) includes a plurality of main pattern portions 103-2a arranged along the second direction Y, and connecting pattern portions 103-2c of two adjacent main pattern portions 103-2a connected to each other. Each main pattern portion 103-2a of pattern 103-2 (3-2) may have a quadrilateral, rhombus, or square shape. Each main pattern portion 103-2a of pattern 103-2 (3-2) may have a shape corresponding to each main pattern portion 103-1a of pattern 103-1 (3-1).

[0329] Each main pattern portion 103-1a of pattern 3-1 103-1 is positioned closer to the first pattern 101 than each main pattern portion 103-2a of pattern 3-2 103-2.

[0330] Each of the multiple third patterns 103' includes a third-1 pattern 103-1 and a third-2 pattern 103-2, which are respectively connected to a touch controller (not shown). Therefore, with... Figure 19 Compared to the sensor section 10''''' shown, the number of pins for multiple third patterns 103' in the touch controller (not shown) is doubled. However, when the touch controller (not shown) is driven in the first mode (touch drive mode), it applies touch drive signals to multiple first patterns 101. The two touch sensing signals output from the third-1 pattern 103-1 and the third-2 pattern 103-2, respectively, can cancel out the display noise and LGM (Low Ground Mass) caused by poor grounding of the object acting on the sensor section 10'''''', thus having the advantage of improving sensing sensitivity.

[0331] Figure 21 It is used for explanation Figure 20 The diagram shows a variation of pattern 103-1 (3-1) and pattern 103-2 (3-2).

[0332] See Figure 21The third-1 pattern 103-1' includes a plurality of main pattern portions 103-1a' and 103-1b' arranged along the second direction Y, and a connecting pattern portion 103-1c' for two adjacent main pattern portions 103-1a' and 103-1b' among the plurality of main pattern portions 103-1a' and 103-1b'. Each main pattern portion 103-1a' and 103-1b' of the third-1 pattern 103-1' may include a first main pattern portion 103-1a' and a second main pattern portion 103-1b'. The first main pattern portion 103-1a' and the second main pattern portion 103-1b' may have shapes that are symmetrical to each other in the first direction X. For example, the first main pattern portion 103-1a' has an inverted triangular shape, and the second main pattern portion 103-1b' may also have an inverted triangular shape. The first main pattern portion 103-1a' and the second main pattern portion 103-1b' may be electrically connected to each other.

[0333] Pattern 103-2' (3-2) includes a plurality of main pattern portions 103-2a' and 103-2b' arranged along the second direction Y, and a connecting pattern portion 103-2c' for two adjacent main pattern portions 103-2a' and 103-2b' among the interconnected main pattern portions 103-2a' and 103-2b'. Each main pattern portion 103-2a' and 103-2b' of pattern 103-2' may include a first main pattern portion 103-2a' and a second main pattern portion 103-2b'. The first main pattern portion 103-2a' and the second main pattern portion 103-2b' may have shapes that are symmetrical to each other in the first direction X. For example, the first main pattern portion 103-2a' may have an inverted triangular shape, and the second main pattern portion 103-2b' may also have an inverted triangular shape. The first main pattern portion 103-2a' and the second main pattern portion 103-2b' may be electrically connected to each other.

[0334] The main pattern parts 103-1a' and 103-1b' of pattern 3-1 and the main pattern parts 103-2a' and 103-2b' of pattern 3-2 are arranged alternately one by one along the second direction Y.

[0335] Figure 22 It is a brief illustration Figure 19 A diagram of another variation of the sensor section 10''''' shown.

[0336] like Figure 22 As shown, the sensor unit 10''''''' includes first to fourth patterns 101', 102, 103, and 104.

[0337] and Figure 19 Compared to the 10''''' sensor section, Figure 22The sensor section 10'''''''' differs in several first patterns 101'.

[0338] Each of the multiple first patterns 101 includes a first-1 pattern 101-1 and a first-2 pattern 101-2.

[0339] Pattern 101-1 includes a plurality of main pattern portions 101-1a arranged along a first direction X and a connecting pattern portion 101-1c of two adjacent main pattern portions 101-1a among the plurality of main pattern portions 101-1a. Each main pattern portion 101-1a of pattern 101-1 may have a quadrilateral, rhombus or square shape, and may have an opening that allows each main pattern portion 103-2a of pattern 101-2 to be arranged inside.

[0340] Pattern 101-2 includes a plurality of main pattern portions 101-2a arranged along a first direction X, and connecting pattern portions 101-2c of two adjacent main pattern portions 101-2a connected to each other. Each main pattern portion 101-2a of pattern 101-2 may have a quadrilateral, rhombus, or square shape. Each main pattern portion 101-2a of pattern 101-2 may have a shape corresponding to each main pattern portion 101-1a of pattern 101-1.

[0341] Each main pattern portion 101-1a of pattern 101-1 is positioned closer to the third pattern 103 than each main pattern portion 101-2a of pattern 101-2.

[0342] Each of the multiple first patterns 101' includes a first-1 pattern 101-1 and a first-2 pattern 101-2, and the first-1 pattern 101-1 and the first-2 pattern 101-2 are respectively connected to a touch controller (not shown). Therefore, with Figure 19 Compared to the sensor unit 10''''' shown, the number of pins for multiple first patterns 101' in the touch controller (not shown) is doubled. However, when the touch controller (not shown) operates in the first mode (touch drive mode), applying a touch drive signal to the first-1 pattern 101-1 and simultaneously applying a touch drive signal with a 180-degree phase reversal of the touch drive signal to the first-2 pattern 101-2, flickering on the display panel having the sensor unit 10''''''' can be reduced or eliminated. The flickering refers to... Figure 19 The simultaneous application of touch drive signals to at least two of the multiple first patterns 101 superimposed on the display panel causes flickering on the display panel. Figure 22In the sensor section 10''''''', two touch drive signals with opposite phases are applied simultaneously to each of the first patterns 101'. Therefore, even if the two touch drive signals are added together, their sum is still '0', so it does not affect the display panel and thus does not cause the flickering phenomenon.

[0343] On the other hand, although not shown in another figure, the first-1 pattern 101-1 and the first-2 pattern 101-2 of each first pattern 101' may also have the following characteristics: Figure 21 The pattern shape shown.

[0344] Figure 23 It is a brief illustration Figure 19 A diagram showing another variation of the sensor section 10'''''.

[0345] like Figure 23 As shown, the sensor unit 10''''''''' includes first to fourth patterns 101', 102, 103', and 104.

[0346] and Figure 19 Compared to the 10''''' sensor section, Figure 23 The sensor section 10' differs in terms of multiple first patterns 101' and third patterns 103'. Figure 22 The multiple first patterns 101' shown are identical, and the multiple third patterns 103' are the same as... Figure 20 The multiple third patterns 103' shown are identical.

[0347] use Figure 23 With a 10' ... Figure 20 and Figure 22 The technical effects of the sensor section 10'''''', 10'''''' are as follows: It can counteract display noise acting on the sensor section 10''''''' and LGM (Low Ground Mass) caused by poor grounding of the object, thereby improving sensing sensitivity and reducing or eliminating flicker on the display panel having the sensor section 10'''''''.

[0348] Figure 24 It is a brief illustration Figure 5 A diagram of the sensor section 100 is shown.

[0349] like Figure 24As shown, the sensor unit 100 includes a first pattern 101, a third pattern 103, and a fourth pattern 104. The first pattern 101 can be named a first pattern in the first direction X, the third pattern 103 can be named a first pattern in the second direction Y, and the fourth pattern 104 can be named a second pattern in the second direction Y.

[0350] Figure 24 The sensor unit 100 shown has multiple first patterns 101 connected to a touch controller (not shown) in a dual-route manner. Therefore, it has the advantage of expanded touch bandwidth and also the advantage of not causing half-distortion.

[0351] Figure 24 The plurality of fourth patterns 104 of the sensor unit 100 shown may float without being electrically connected to the touch controller (not shown). When the touch controller (not shown) drives the sensor unit 100 in a third mode (or downlink mode) for sensing pen signals, it can sense the pen signals through the plurality of third patterns 103. The pen signals from the plurality of third patterns 103 are transmitted from the plurality of fourth patterns 104 via capacitive coupling. Alternatively, the touch controller (not shown) can also directly receive pen signals through the plurality of first patterns 101.

[0352] Figure 24 At least one of the plurality of fourth patterns 104a of the sensor unit 100 shown can be electrically connected to a touch controller (not shown). When the touch controller (not shown) operates the sensor unit 100 in a first mode (touch sensing mode), it can control the plurality of fourth patterns 104 to be electrically grounded. This can minimize the influence of the plurality of fourth patterns 104 in the first mode.

[0353] on the other hand, Figure 24 When the sensor unit 100 shown uses multiple first patterns 101 to drive the stylus, the total resistance of the multiple first patterns 101 and the traces connected to them is relatively larger than that in the case of not using the dual routing method. Therefore, the power consumption is relatively higher in the second mode (uplink mode). However, the multiple fourth patterns 104 are either not used or almost all of them are not used. Therefore, it has the advantage of being able to reduce the number of channels of the touch controller (not shown).

[0354] Figure 25 It is a brief illustration Figure 24 A diagram showing a modified example of the sensor section 100.

[0355] like Figure 25 As shown, the sensor unit 100''' includes a first pattern 101, a third pattern 103, and a fourth pattern 104.

[0356] and Figure 24Compared to the sensor unit 100 shown, Figure 25 The sensor section 100''' shown is connected in parallel at the lower ends of multiple fourth patterns 104 in pairs. The parallel connection portion differs from the electrical connection of the touch controller (not shown).

[0357] When operating in a first mode (touch sensing mode), the touch controller (not shown) can utilize multiple first patterns 101 and multiple third patterns 103. Specifically, the touch controller (not shown) can be configured to apply touch drive signals to the multiple first patterns 101 and receive touch sensing signals from the multiple third patterns 103. Figure 6 or Figure 10 The described method runs the first mode.

[0358] When the touch controller (not shown) operates in the second mode (uplink mode), it can use multiple fourth patterns 104 as patterns for driving the stylus. In this case, with Figure 24 Compared to the sensor section 100, the total resistance of the plurality of fourth patterns 104 is relatively reduced because the lower ends of the plurality of fourth patterns 104 are connected in parallel in pairs. Therefore, it has the ability to utilize... Figure 24 The sensor unit 100 has the advantage of reducing power consumption by up to half when driving the stylus.

[0359] Additionally, the touch controller (not shown) can receive pen signals directly through multiple first patterns 101, and can also receive pen signals through multiple third patterns 103. Specifically, pen signals from the multiple first patterns 101 can be received via, for example, through... Figure 9 , Figure 11a , Figure 11b In any of the sensing methods, pen signals from multiple third patterns 103 can be transmitted from multiple fourth patterns 104 via capacitive coupling to be sensed.

[0360] Figure 26 It is a brief illustration Figure 25 A diagram showing a modified example of the sensor section 100'''.

[0361] like Figure 26 As shown, the sensor unit 100'''' includes a first pattern 101', a third pattern 103 and a fourth pattern 104.

[0362] and Figure 25 Compared to the sensor section 100''' shown, Figure 26 The sensor section 100 shown differs in several first patterns 101'.

[0363] Each of the plurality of first patterns 101' includes a first-1 pattern 101l and a first-2 pattern 101r. The first-1 pattern 101l and the first-2 pattern 101r are arranged in a first direction X and are arranged adjacent to each other. The first-1 pattern 101l and the first-2 pattern 101r are physically spaced apart from each other, configured to form capacitive coupling between them.

[0364] One end (left end) of pattern 101l is electrically connected to a touch controller (not shown) via trace 101cl, and the other end (right end) of pattern 101r is electrically connected to a touch controller (not shown) via trace 101cr.

[0365] Pattern 101l of the first-1 includes a plurality of main pattern portions 101-1a arranged along a first direction X and a connecting pattern portion 101-1c of two adjacent main pattern portions 101-1a among the plurality of main pattern portions 101-1a. Each main pattern portion 101-1a of pattern 101l of the first-1 may have a quadrilateral, rhombus or square shape, and may have an opening that allows each main pattern portion 101-2a of pattern 101r of the first-2 to be arranged inside.

[0366] The first-second pattern 101r includes a plurality of main pattern portions 101-2a arranged along a first direction X, and connecting pattern portions 101-2c of two adjacent main pattern portions 101-2a connected to each other. Each main pattern portion 101-2a of the first-second pattern 101r may have a quadrilateral, rhombus, or square shape. Each main pattern portion 101-2a of the first-second pattern 101r may have a shape corresponding to each main pattern portion 101-1a of the first-first pattern 101l.

[0367] Each main pattern portion 101-1a of the first-1 pattern 101l is positioned closer to the third pattern 103 than each main pattern portion 101-2a of the first-2 pattern 101r.

[0368] Each of the multiple first patterns 101' includes a first-1 pattern 101l and a first-2 pattern 101r, and the first-1 pattern 101l and the first-2 pattern 101r are respectively connected to a touch controller (not shown) via traces 101cl and 101cr. Therefore, with Figure 25Compared to the sensor section 100''' shown, the number of pins for multiple first patterns 101' in the touch controller (not shown) is doubled. However, when the touch controller (not shown) is driven in the first mode (touch drive mode), it applies touch drive signals to multiple third patterns 103. The two touch sensing signals output from the first-1 pattern 101l and the first-2 pattern 101r respectively can cancel out the display noise and LGM (Low Ground Mass) caused by poor grounding of the object acting on the sensor section 100'''', thus having the advantage of improving sensing sensitivity.

[0369] On the other hand, although not shown in another figure, the first-1 pattern 101l and the first-2 pattern 101r of each first pattern 101' may also have the following characteristics: Figure 21 The pattern shape shown.

[0370] On the other hand, the touch controller (not shown) can utilize multiple fourth patterns 104 to operate a second mode (uplink mode).

[0371] Additionally, the touch controller (not shown) can operate in a third mode (downlink mode) using multiple first patterns 101' and multiple third patterns 103. The touch controller (not shown) can be configured to receive pen signals transmitted from the fourth pattern 104 to the third patterns 103 via capacitive coupling through the multiple third patterns 103. The touch controller (not shown) can also be configured to directly receive pen signals sensed by the multiple first patterns 101'.

[0372] Figure 27 It is a brief illustration Figure 25 A diagram showing another variation of the sensor section 100'''.

[0373] like Figure 27 As shown, the sensor unit 100''''' includes a first pattern 101, a third pattern 103' and a fourth pattern 104.

[0374] and Figure 25 Compared to the sensor section 100''' shown, Figure 27 The sensor section 100 shown differs in several third patterns 103'.

[0375] Each of the multiple third patterns 103' includes a third-1 pattern 103-1 and a third-2 pattern 103-2 arranged adjacent to each other.

[0376] Pattern 103-1 of pattern 3-1 includes a plurality of main pattern portions 103-1a arranged along the second direction Y and a connecting pattern portion 103-1c of two adjacent main pattern portions 103-1a among the plurality of main pattern portions 103-1a. Each main pattern portion 103-1a of pattern 3-1 may have a quadrilateral, rhomboid or square shape, and may have an opening that allows each main pattern portion 103-2a of pattern 3-2 to be arranged inside.

[0377] Pattern 103-2 (3-2) includes a plurality of main pattern portions 103-2a arranged along the second direction Y, and connecting pattern portions 103-2c of two adjacent main pattern portions 103-2a connected to each other. Each main pattern portion 103-2a of pattern 103-2 (3-2) may have a quadrilateral, rhombus, or square shape. Each main pattern portion 103-2a of pattern 103-2 (3-2) may have a shape corresponding to each main pattern portion 103-1a of pattern 103-1 (3-1).

[0378] Each main pattern portion 103-1a of pattern 3-1 103-1 is positioned closer to the first pattern 101 than each main pattern portion 103-2a of pattern 3-2 103-2.

[0379] Each of the multiple third patterns 103' includes a third-1 pattern 103-1 and a third-2 pattern 103-2, which are respectively connected to a touch controller (not shown). Therefore, with... Figure 25 Compared to the sensor section 100''' shown, the number of pins for multiple first patterns 101' in the touch controller (not shown) is doubled. However, when the touch controller (not shown) is driven in the first mode (touch drive mode), and applies a touch drive signal to the 3-1 pattern 103-1 and a touch drive signal with a 180-degree phase reversal of the touch drive signal to the 3-2 pattern 103-2, flicker occurring on the display panel having the sensor section 100''''' can be reduced or eliminated.

[0380] On the other hand, although not shown in a separate diagram, the 3-1 pattern 103-1 and the 3-2 pattern 103-2 of each third pattern 103' can also have the following characteristics: Figure 21 The pattern shape shown.

[0381] Figure 28 It is a brief illustration Figure 25 A diagram showing another variation of the sensor section 100'''.

[0382] like Figure 28As shown, the sensor unit 100 includes a first pattern 101', a third pattern 103', and a fourth pattern 104.

[0383] and Figure 25 Compared to the 100''' sensor section, Figure 28 The sensor section 100' differs in terms of multiple first patterns 101' and third patterns 103'. Figure 26 The multiple first patterns 101' shown are identical, and the multiple third patterns 103' are the same as... Figure 27 The multiple third patterns 103' shown are identical.

[0384] use Figure 28 In the case of a 100' ... Figure 26 and Figure 27 The technical effects of the sensor section 100'''', 100''''' are as follows: It can counteract display noise acting on the sensor section 100'''' and LGM (Low Ground Mass) caused by poor grounding of the object, thus improving sensing sensitivity and reducing or eliminating flicker in the display panel having the sensor section 100'''''.

[0385] Figure 29 This is a block diagram of an electronic device according to a fourth embodiment of the present invention.

[0386] See Figure 29 The electronic device according to the fourth embodiment of the present invention includes a sensor unit 1500, a display panel 1000, a controller 2000, and a display controller 3000.

[0387] The sensor unit 1500 may be included in the display panel 1000, or it may be configured separately. The sensor unit 1500 may include... Figures 4 to 25 Any one of the sensor units shown.

[0388] The sensor unit 1500 includes a plurality of first electrodes and a plurality of second electrodes. The plurality of first electrodes become a plurality of driving electrodes Tx0, Tx1, Tx2, Tx3, Tx4, Tx5, Tx6, Tx7, and the plurality of second electrodes become a plurality of receiving electrodes Rx0, Rx1, Rx2, Rx3.

[0389] Multiple driving electrodes Tx0, Tx1, Tx2, Tx3, Tx4, Tx5, Tx6, and Tx7 can be Figures 4 to 25 The multiple first patterns 101 shown, and the multiple receiving electrodes Rx0, Rx1, Rx2, and Rx3 can be Figures 4 to 25The multiple third patterns 103 are shown. Conversely, the multiple driving electrodes Tx0, Tx1, Tx2, Tx3, Tx4, Tx5, Tx6, and Tx7 can be Figures 4 to 25 The multiple third patterns 103 shown, and the multiple receiving electrodes Rx0, Rx1, Rx2, and Rx3 can be Figures 4 to 25 The multiple first patterns 101 shown.

[0390] The controller 2000 controls the sensor unit 1500. The controller 2000 may include... Figures 4 to 25 Any one of the touch controllers shown. Controller 2000 may include a driving and sensing unit 2100 and a control unit 2200.

[0391] The controller 2000 can sequentially provide drive signals to the plurality of drive electrodes Tx0, Tx1, Tx2, Tx3, Tx4, Tx5, Tx6, Tx7 of the sensor unit 1500, or simultaneously provide predetermined drive signals to at least two of the plurality of drive electrodes Tx0, Tx1, Tx2, Tx3, Tx4, Tx5, Tx6, Tx7.

[0392] The controller 2000 receives sensing signals output from multiple receiving electrodes Rx0, Rx1, Rx2, and Rx3 of the sensor unit 1500. The sensing signals may include information on the capacitance change between each receiving electrode and its adjacent driving electrode, LGM noise signals, and display noise signals, etc.

[0393] Each receiving electrode Rx0, Rx1, Rx2, and Rx3 can be composed of a pair of receiving electrodes. For example, the 0th receiving electrode Rx0 includes a pair of receiving electrodes Rx0a and Rx0b. Multiple pairs of receiving electrodes Rx0a and Rx0b can be arranged alternately. Multiple 0a receiving electrodes Rx0a are electrically connected to each other, and multiple 0b receiving electrodes Rx0b are electrically connected to each other.

[0394] The 0a receiving electrode Rx0a is configured to form a dominant mutual capacitance with the 0th driving electrode Tx0, the second driving electrode Tx2, the fourth driving electrode Tx4, and the sixth driving electrode Tx6. The 0b receiving electrode Rx0b can be configured to form a dominant mutual capacitance with the first driving electrode Tx1, the third driving electrode Tx3, the fifth driving electrode Tx5, and the seventh driving electrode Tx7. On the other hand, the 0a receiving electrode Rx0a can be configured to form a relatively small mutual capacitance with the first driving electrode Tx1, the third driving electrode Tx3, the fifth driving electrode Tx5, and the seventh driving electrode Tx7. The 0b receiving electrode Rx0b can be configured to form a relatively small mutual capacitance with the 0th driving electrode Tx0, the second driving electrode Tx2, the fourth driving electrode Tx4, and the sixth driving electrode Tx6.

[0395] The remaining receiving electrodes Rx1, Rx2, and Rx3 can also be configured in the same way as the 0th receiving electrode Rx0.

[0396] The controller 2000 can perform analog-to-digital conversion on the sensing signals output from multiple receiving electrodes Rx0, Rx1, Rx2, and Rx3 to output digital sensing signals.

[0397] The controller 2000 can output differential signals from two of the sensing signals output from multiple receiving electrodes Rx0, Rx1, Rx2, and Rx3, and can perform analog-to-digital conversion on the output signals. This controller 2000 can detect whether a touch has occurred and / or the touch location based on the output digital signal.

[0398] The controller 2000 may include a driving and sensing unit 2100 that applies driving signals to at least one driving electrode Tx0, Tx1, Tx2, Tx3, Tx4, Tx5, Tx6, Tx7 of the sensor unit 1500 and receives sensing signals from a plurality of receiving electrodes Rx0, Rx1, Rx2, Rx3 of the sensor unit 1500, and a control unit 2200 that controls the driving and sensing unit 2100.

[0399] Multiple scan lines (or gate lines) and multiple data lines can be configured on the display panel 1000. Subpixels can be configured in the areas where scan lines and data lines intersect.

[0400] The display panel 1000 may include active areas configured with multiple sub-pixels and inactive areas (inactive spaces or rings) located outside the active areas. The active areas may constitute the display screen of an electronic device. The display screen may have a landscape shape with a horizontal length longer than its vertical length. Alternatively, the display screen may have a portrait shape with a vertical length longer than its horizontal length.

[0401] The display controller 3000 controls the display panel 1000 and includes a gate drive circuit 3100, a display control unit 3200, and a data drive circuit 3300.

[0402] Figure 30 This diagram illustrates the sensor section in a current landscape orientation.

[0403] Figure 30 The sensor unit shown is configured to detect the touch position of an object such as a finger. This sensor unit consists of a plurality of first patterns 101 extending in a first direction X, which is the major axis, and a plurality of third patterns 103 extending in a second direction Y, which is the minor axis. The plurality of first patterns 101 and the plurality of third patterns 103 are arranged to intersect each other and are electrically insulated from each other.

[0404] exist Figure 30In the sensor section shown, multiple third patterns 103 function as driving electrodes TX to which touch driving signals are applied, and multiple first patterns 101 function as receiving electrodes RX to which touch sensing signals are output. Each first pattern 101 is separated into two based on a virtual cutting line CL.

[0405] exist Figure 30 In the diagram, a total of 112 first patterns 101 are composed of multiple patterns 101. 56 first patterns 101 are arranged on the left side and 56 first patterns 101 are arranged on the right side, with the cutting line CL as the reference. Furthermore, a total of 82 third patterns 103 are composed of multiple patterns 103. Therefore, they are used for control... Figure 30 The touch controller (not shown) of the sensor section has a total of 194 channels (or pins).

[0406] Figure 31 (A) to (B) are diagrams used to illustrate another sensor unit in the existing landscape configuration.

[0407] Figure 31 The existing sensor unit shown in (A) can not only sense the position of objects such as fingers, but also drive or sense the position of a stylus. Therefore, Figure 31 The existing sensor section shown in (A) is in Figure 30 The sensor section shown is further configured with a second pattern 102 and a fourth pattern 104. Additionally, to remove noise, each third pattern 103, which functions as a receiving electrode RX, is as follows: Figure 29 As shown, it consists of a pair of electrodes 103a and 103b arranged alternately along the second direction Y.

[0408] and Figure 30 Compared to existing sensor units, Figure 31 The existing sensor unit shown in (A) also has multiple second patterns 102 and multiple fourth patterns 104. Each third pattern 103 is composed of a pair of electrodes 103a and 103b. Therefore, the total number of channels of the touch controller (not shown) is 358, which is the sum of the number of multiple first patterns 101 arranged on the left side (56) with the cutting line CL as the reference, the number of multiple first patterns arranged on the right side (56), the number of multiple third patterns 103 (164), and the number of multiple fourth patterns 104 (82). Among them, the multiple second patterns 102 are not electrically connected to the touch controller (not shown) and are therefore excluded from the number of channels of the touch controller (not shown).

[0409] and Figure 31 Compared to the sensor section shown in (A), in Figure 31In the sensor unit shown in (B), the plurality of first patterns 101 function as receiving electrodes RX, and the plurality of third patterns 103 function as driving electrodes TX. Each first pattern 101 is composed of a pair of electrodes 101a and 101b arranged alternately along the first direction X.

[0410] Compared with Figure 31 the existing sensor unit shown in (A), in Figure 31 the existing sensor unit shown in (B), each first pattern 101 is composed of a pair of electrodes 101a and 101b arranged alternately along the first direction X, so the total number of channels of the touch controller (not shown) is 388.

[0411] After comparison Figure 31 between (A) and Figure 31 (B), due to the shape characteristics of the landscape screen, the touch controller (not shown) for Figure 31 the sensor unit shown in (B) requires a relatively larger number of channels.

[0412] Figure 32 (A) to (B) are diagrams for explaining the sensor unit of an electronic device according to a fifth embodiment of the present invention.

[0413] Figure 32 The sensor unit shown in (A) is connected to a touch controller (not shown) in a dual-routing manner of the plurality of first patterns 101 Figure 5 The shown sensor unit, each third pattern 103 is as Figure 29 shown, composed of a pair of electrodes 103a and 103b arranged alternately along the second direction Y.

[0414] For Figure 32 the touch controller (not shown) of the sensor unit shown in (A), the number of channels is 276. Among them, the plurality of fourth patterns 104 are not electrically connected to the touch controller (not shown). Compared with the touch controller (not shown) of the existing sensor unit shown in (A) for Figure 31 , the plurality of first patterns 101 connected in a dual-routing manner also function in the second mode of driving a stylus, so it has the advantage of being able to relatively reduce the number of channels of the touch controller (not shown) by about 22%.

[0415] Figure 32 The sensor unit shown in (B) is Figure 5 In the shown sensor unit, each first pattern 101 is as Figure 29 composed of a pair of electrodes 101a and 101b arranged alternately along the first direction X.

[0416] For Figure 32The number of channels of the touch controller (not shown) of the sensor unit shown in (B) is 306. Among them, a plurality of fourth patterns 104 are not electrically connected to the touch controller (not shown). For Figure 31 Compared with the touch controller (not shown) of the existing sensor unit shown in (B), the plurality of first patterns 101 connected in a dual-routing manner also function in the second mode of driving a stylus, so it has the advantage of being able to relatively reduce the number of channels of the touch controller (not shown) by about 22%.

[0417] Has Figure 31 And Figure 32 When the size of the display screen of the electronic device having the sensor unit shown is the size of the screen of a general smartphone, for example, 6.9 inches, there is no particular problem. However, if the size of the display screen increases to 11 inches to 16 inches like a tablet or a foldable device, Figure 31 In the sensor unit shown, the lengths of the first to fourth patterns 101, 102, 103, 104 also become longer together, so the total resistance and capacitance value of the sensor unit increase. The increase in resistance and capacitance values causes the working bandwidth of the touch drive signal applied to the touch drive electrode TX and the pen drive signal applied to the stylus drive electrode STX to become narrower, so there may be a problem that the required working bandwidth at the time of design cannot be obtained.

[0418] On the contrary, Figure 32 In the case of the embodiment of the present invention shown, since there is no dedicated channel for the stylus drive electrode STX, the resistance or capacitance value can be reduced, so it has the advantage of being able to expand the working bandwidth required for design.

[0419] Figure 33 It is a block diagram of an electronic device according to a sixth embodiment of the present invention.

[0420] Compared with Figure 29 The electronic device according to the fourth embodiment shown, Figure 33 The electronic device shown has the following differences.

[0421] Figure 29 In the sensor unit 1500 shown, a plurality of first electrodes become a plurality of drive electrodes Tx0, Tx1, Tx2, Tx3, Tx4, Tx5, Tx6, Tx7, and a plurality of second electrodes become a plurality of receiving electrodes Rx0, Rx1, Rx2, Rx3. And in Figure 33 In the sensor unit 1500' shown, on the contrary, a plurality of first electrodes become a plurality of receiving electrodes Rx0, Rx1, Rx2, Rx3, Rx4, Rx5, Rx6, Rx7, and a plurality of second electrodes become a plurality of drive electrodes Tx0, Tx1, Tx2, Tx3.

[0422] Multiple driving electrodes Tx0, Tx1, Tx2, and Tx3 can be Figures 4 to 25 and Figure 32 The plurality of first patterns 101 shown, and the plurality of receiving electrodes Rx0, Rx1, Rx2, Rx3, Rx4, Rx5, Rx6, and Rx7 can be Figures 4 to 25 and Figure 32 The multiple third patterns 103 are shown. Conversely, the multiple driving electrodes Tx0, Tx1, Tx2, and Tx3 can be Figures 4 to 25 and Figure 32 The multiple third patterns 103 shown, and the multiple receiving electrodes Rx0, Rx1, Rx2, Rx3, Rx4, Rx5, Rx6, and Rx7 can be Figures 4 to 25 and Figure 32 The multiple first patterns 101 shown.

[0423] Multiple first electrodes, such as Figure 29 Become multiple driving electrodes or Figure 33 The number of receiving electrodes can be determined by the control unit 2200.

[0424] When the control unit 2200 applies a drive signal to a plurality of first electrodes, the plurality of first electrodes become a plurality of drive electrodes; when the control unit applies a drive signal to a plurality of second electrodes, the plurality of second electrodes can become a plurality of receiving electrodes.

[0425] Multiple driving electrodes Tx0, Tx1, Tx2, Tx3 and multiple receiving electrodes Rx0, Rx1, Rx2, Rx3, Rx4, Rx5, Rx6, Rx7 can be arranged in a mutually intersecting manner. Each driving electrode Tx0, Tx1, Tx2, Tx3 extends towards a second axis, and each receiving electrode Rx0, Rx1, Rx2, Rx3, Rx4, Rx5, Rx6, Rx7 can extend towards a first axis direction different from the first axis direction. The first axis direction can be perpendicular to the second axis direction.

[0426] A portion of the driving electrodes Tx0, Tx1, Tx2, Tx3, etc., can be configured to form a mutual capacitance Cm with a portion of the even-numbered receiving electrodes Rx0, Rx2, Rx4, Rx6, etc., of the multiple receiving electrodes Rx0, Rx1, Rx2, etc. The remaining driving electrodes Tx0b, Tx1b, Tx2b, Tx3b, etc., of the multiple driving electrodes Tx0, Tx1, Tx2, Tx3, etc., can be configured to form a mutual capacitance Cm with the remaining receiving electrodes Rx1, Rx3, Rx5, Rx7, etc., of the odd-numbered receiving electrodes Rx0, Rx1, Rx2, etc., of the multiple receiving electrodes Rx7, Rx1, Rx2, etc.

[0427] Among the multiple driving electrodes Tx0, Tx1, Tx2, Tx3, some driving electrodes Tx0a, Tx1a, Tx2a, Tx3a, ... can be configured to be adjacent to the even-numbered receiving electrodes Rx0, Rx2, Rx4, Rx6, ... among the multiple receiving electrodes Rx0, Rx1, Rx2, ... and can be configured to be separated from the remaining odd-numbered receiving electrodes Rx1, Rx3, Rx5, Rx7, ... by a predetermined distance rather than being adjacent.

[0428] At least one other electrode may be configured between the partial driving electrodes Tx0a, Tx1a, Tx2a, Tx3a, ... and the remaining receiving electrodes Rx1, Rx3, Rx5, Rx7, ... of the odd-numbered electrodes. The other electrode may be the partial receiving electrodes Rx0, Rx2, Rx4, Rx6, ... of the even-numbered electrodes.

[0429] The remaining driving electrodes Tx0b, Tx1b, Tx2b, Tx3b, ... among the multiple driving electrodes Tx0, Tx1, Tx2, Tx3 can be configured to be adjacent to the remaining receiving electrodes Rx1, Rx3, Rx5, Rx7, ... of the odd-numbered receiving electrodes Rx0, Rx1, Rx2, ... and can be configured to be separated from the even-numbered receiving electrodes Rx0, Rx2, Rx4, Rx6, ... by a predetermined distance rather than being adjacent to them.

[0430] At least one other electrode may be configured among the remaining driving electrodes Tx0b, Tx1b, Tx2b, Tx3b, ... and the even-numbered partial receiving electrodes Rx0, Rx2, Rx4, Rx6, ... The other electrode may be the remaining receiving electrodes Rx1, Rx3, Rx5, Rx7, ... of the odd-numbered electrode.

[0431] The driving signals applied to the remaining driving electrodes Tx0b, Tx1b, Tx2b, Tx3b, ... can be the reverse driving signals that are only 180 degrees phase-reversed among the driving signals applied to some driving electrodes Tx0a, Tx1a, Tx2a, Tx3a, ...

[0432] For example, the driving signal applied to Tx0b of the pair of driving electrodes Tx0a and Tx0b of the 0th driving electrode Tx0 is an inverted driving signal that reverses the driving signal applied to Tx0a.

[0433] Figure 33The illustrated electronic device has the advantage of being able to simultaneously apply drive signals to all drive electrodes Tx0, Tx1, Tx2, Tx3, ... of the sensor section 1500' without causing flickering on the display panel. Furthermore, since multi-drive of all drive electrodes Tx0, Tx1, Tx2, Tx3, ... is possible, the drive time for performing mutual sensing can be reduced. Moreover, the turn-on time of the analog front-end (AFE) can be reduced, thus further reducing power consumption.

[0434] Figure 34 It is used to explain the basis Figures 4 to 33 A diagram showing the stackup structure of electronic devices in multiple embodiments.

[0435] The electronic device may include a cover layer 310, a sensor unit 320, a display unit 330, a magnetic field shielding layer 340, and a conductive layer 350.

[0436] The cover layer 310 is disposed on the display unit 330 and is made of transparent material, so that the tip of the stylus can directly contact the top of the cover layer 310 (or the touch surface).

[0437] The display unit 330 is disposed below the cover layer 310 and provides predetermined information visually in response to the control of a display controller (not shown). For example, the display unit 330 may be a flexible LCD module or a flexible OLED module.

[0438] A sensor unit 320 capable of sensing not only fingers but also driving and / or sensing a stylus can be disposed between the cover layer 310 and the display unit 330. The sensor unit 320 may include the above-mentioned... Figures 4 to 33 At least one of the sensor components described.

[0439] The magnetic field shielding layer 340 can cut off the magnetic field to prevent other electronic components inside the electronic device from being affected by the magnetic field. In addition, it can diffuse heat emitted from the electronic components and also cut off electromagnetic waves (EMI) from the electronic components.

[0440] The conductive layer 350 can be a metal such as copper or aluminum, or an alloy made by adding other metals or non-metals to at least one metal. The conductive layer 350 can have a ground potential in terms of electrical properties.

[0441] Figure 35 Is as Figures 4 to 34 A simplified structural diagram of an example of a foldable electronic device.

[0442] The foldable device includes an internal touchscreen 200 and an external touchscreen 250.

[0443] As mentioned above, in Figures 4 to 34 In the illustrated electronic device, the sensor unit is capable not only of sensing objects such as fingers, but also of driving and / or sensing a stylus. Therefore, the foldable device, as an electronic device according to an embodiment of the present invention, does not require... Figure 4 The digital converter is described. Therefore, the digital converter does not need to be attached to the bottom of the internal touch screen 200 and the external touch screen 250, which can prevent an increase in the overall thickness and manufacturing cost of the foldable device.

[0444] In addition to the internal touchscreen, the external touchscreen also supports stylus functionality.

[0445] In addition, the first pattern is connected to the touch controller in a dual-route manner, so the connection conditions of the driving, receiving, grounding, floating and other sensors can be flexibly controlled according to the user's requirements when the object touches or the stylus touches.

[0446] In addition, there is no need to switch through the multiplexer in the touch controller, thus preventing current damage caused by the resistance of the multiplexer itself and simplifying the structure of electronic devices.

[0447] In addition, in the case of large-screen tablets or foldable devices, there is no need for an additional stylus sensing sensor, so the number of touch drive trace channels is reduced. Therefore, the number of channels is significantly reduced compared to existing finger touch and stylus touch screens, thus enabling a significant reduction in the width-direction thickness of electronic devices.

[0448] In addition, since no additional stylus sensing sensor is required, the thickness of the display panel and manufacturing costs will not increase, and stylus functionality can be achieved on both the inside and outside of the touchscreen of the foldable device.

[0449] Figure 36 This is a perspective view of a stylus pen 100 according to an embodiment of the present invention.

[0450] Reference Figure 36 According to one embodiment of the present invention, the stylus 100 includes a housing 101 and a core 102.

[0451] The outer casing 101 forms the appearance of the stylus 100. A predetermined space is formed inside the outer casing 101, and it has an elongated shape in one direction. The outer casing 101 can be formed by combining two or more parts together, or it can be formed as a single piece.

[0452] The outer casing 101 may be made of a non-conductive synthetic resin material.

[0453] The housing 101 may include a first housing 101a and a second housing 101b. The first housing 101a and the second housing 101b may be combined with each other to form the appearance of the stylus 100. Various components are housed inside the first housing 101a and the second housing 101b.

[0454] The housing 101 may be equipped with a button portion 109. The button portion 109 may be located on the outer side of the middle of the second housing 101b. The button portion 109 may be for performing specific actions of the stylus 100. For example, it may be a mechanical or contact button for performing a cancel action.

[0455] The core 102 includes one end disposed outside the housing 101, and the remaining portion other than the one end disposed inside the housing 101. The one end of the core 102 may also be named a pen tip.

[0456] A portion of one end of the core 102 can move into the housing 101 under the influence of an external force. The greater the external force, the larger the volume of the portion of the core 102 inside the housing 101. When the applied external force decreases, the portion of one end of the core 102 re-extends out of the housing 101 through the mechanical action of components inside the housing 101. When the external force disappears, the portion of one end of the core 102 returns to its initial state.

[0457] The following is for reference Figures 37 to 38 Explain the internal structure of the outer casing 101.

[0458] Figure 37 yes Figure 36 The illustration shows a cross-sectional view of part A of the stylus 100. Figure 38 yes Figure 37 The diagram shows a detailed cross-sectional view of the inductor section 120.

[0459] Reference Figure 37 and Figure 38 According to one embodiment of the present invention, the stylus 100 includes a buffer member 115, an inductor portion 120 and a capacitor portion (not shown) disposed inside the housing 101.

[0460] A buffer member 115 is disposed inside the housing 101, between one end of the ferrite core 121 and the inner surface of the housing 101. The buffer member 115 may be disposed inside the tapered portion 101t of the housing 101. The tapered portion 101t of the housing 101 is the portion of the two ends of the housing 101 adjacent to one end of the core 102, and has a shape in which its width or width decreases as it approaches one end of the housing 101.

[0461] The buffer member 115 has a conical or pyramidal shape and a through hole that passes through one end of the ferrite core 121 and the body 102a of the core 102. The inner surface of the through hole can have a shape corresponding to the outer surface of one end of the ferrite core 121 and the outer surface of the body 102a of the core 102. The body 102a of the core 102 is the portion of the core 102 that is elongated in one direction and disposed within the through hole of the ferrite core 121.

[0462] To buffer the ferrite core 121 and the housing 101, the buffer component 115 can be made of an elastic material such as rubber. This buffer component 115 can protect the housing 101 or the ferrite core 121, or block external electrical or magnetic influences.

[0463] The buffer member 115 has a shape that surrounds one end of the ferrite core 121 or the lower end 121b of the ferrite core 121.

[0464] An imaginary tangent L1, which is tangent to both the tapered portion 101t of the outer casing 101 and a portion (or pen tip) of the core 102 disposed outside the outer casing 101, forms a predetermined angle θ with the central axis Y of the core 102. Preferably, the predetermined angle θ is within 30°. When the predetermined angle θ is within 30°, the stylus according to one embodiment of the present invention can draw even when tilted at 60° relative to the contact surface.

[0465] The inductor section 120 and the capacitor section (not shown) can form an LC resonant section. The resonant frequency can be set by the inductance L value of the inductor section 120 and the capacitance C value of the capacitor section (not shown). The resonant frequency can vary with the inductance L value of the inductor section 120 or the capacitance C value of the capacitor section (not shown).

[0466] The inductor section 120 includes a ferrite core 121 and a coil section 123 wound around the ferrite core 121.

[0467] The coil portion 123 can be wound with at least one layer of ferrite core 123.

[0468] The ferrite core 121 can be cylindrical or polygonal in shape, and a through hole 121h can be formed along the length of the ferrite core 121 to penetrate the interior.

[0469] The ferrite core 121 has a through portion 121h through which the body 102a of the core 102 passes. Through the through portion 121h, the body 102a of the core 102 can reciprocate linearly along the length direction.

[0470] One end of the ferrite core 121 may have a tapered shape in which the diameter or width decreases towards the end portion. The outer side of the tapered end may include at least one curved surface 121c that bends inward.

[0471] The ferrite core 121 may include an upper end portion 121a and a lower end portion 121b disposed below the upper end portion 121a. The upper end portion 121a and the lower end portion 121b may be integrally formed.

[0472] The upper end portion 121a has the shape of a cylinder, an elliptical cylinder, or a polygonal cylinder. The diameter or width of the cylinder or the polygonal cylinder can be constant, as shown in the figure. Alternatively, the diameter or width of the cylinder, the elliptical cylinder, or the polygonal cylinder may not be constant; the diameter or width of one part may differ from the diameter or width of other parts.

[0473] A portion of the through hole 121h through which the core 102 body 102 is formed is formed inside the upper end portion 121a. The coil portion 123 is disposed outside the upper end portion 121a.

[0474] The remaining portion of the core 102 is formed inside the lower end 121b by the through hole 121h through which the body 102a of the core 102 is formed.

[0475] The lower end portion 121b has a tapered shape whose width gradually tapers from top to bottom, and at least a portion of the outer side of the lower end portion 121b has a curved surface portion 121c that curves inward toward the lower end portion 121b. There may be at least one curved surface portion 121c. The technical effects of a stylus according to an embodiment of the present invention, including a ferrite core 121 having such a curved surface portion 121c, are described below with reference to the accompanying drawings.

[0476] Figure 39 (a) to (b) are used to illustrate Figures 37 to 38 The illustration shows the internal structure and effects of a stylus according to an embodiment of the present invention. Specifically, Figure 39 (b) is Figures 37 to 38 The illustration shows a cross-sectional view of a stylus according to one embodiment of the present invention. Figure 39 (a) is to Figure 39 (b) The ferrite core 121 is replaced with Figure 2 The diagram on the right shows a cross-sectional view of the ferrite core 131'.

[0477] Reference Figure 39 From (a) to (b), in Figure 39 (b) The stylus shown in the figure can be configured such that the ferrite core 121 is more than that in an embodiment of the present invention. Figure 39 The ferrite core 131' in (a) diagram is closer to the predetermined length S below.

[0478] According to this configuration, when using a stylus according to an embodiment of the present invention, the inductor portion 120 including the ferrite core 121 can be moved closer to the receiver side (not shown) disposed below the core 102 of the stylus. Therefore, it has the advantage of increasing the magnitude of the pen signal sensed at the receiver side. This is achieved by reducing the thickness of the buffer member 115 (between the inner and outer surfaces) by adjusting the shape of the ferrite core 121 of the stylus according to an embodiment of the present invention. (Refer to the following...) Figure 40 Detailed explanation.

[0479] Figure 40 (a) through (c) are for further explanation Figures 37 to 38 The illustration shows the internal structure and effects of a stylus according to an embodiment of the present invention. Specifically, Figure 40 (a) is with Figure 39 The same diagram as (a), Figure 40 (b) is with Figure 39 The same diagram as (b), Figure 40 (c) is to arrange the ferrite core 121 in conjunction with... Figure 40 The figure shows the ferrite core 131' in the same position as (a).

[0480] Reference Figure 40 (a) The buffer member 115' has a certain thickness T2 between its inner and outer surfaces. The more the thickness T2 is minimized, the lower the ferrite core 131' can be positioned in the tapered portion 101t of the housing 101. However, due to the structure of the buffer member 115' or other manufacturing engineering reasons, the thickness T2 is limited.

[0481] Wherein, assuming that the thickness T2 is the minimum thickness that the buffer component 115' can have due to the structure of the buffer component 115' or other manufacturing engineering reasons, the existing ferrite core 131' is arranged at the bottom end within the housing 101 as follows: Figure 40 (a)

[0482] Reference Figure 40 (c) The ferrite core 121 is configured with Figure 40 At the same position as the ferrite core 131' in (a), since the ferrite core 121 has a curved surface 121c, the buffer member 115'' is correspondingly located... Figure 40 The buffer member 115' shown in (a) has a different construction. Specifically, the inner surface of the buffer member 115'' has an outwardly bulging surface corresponding to the curved surface 121c of the ferrite core 121.

[0483] The thickness between the outer side surface and the inner side surface formed by a curved surface of the buffer member 115'' varies depending on the position. Specifically, the upper and lower ends of the inner side surface of the buffer member 115'' have the minimum thickness T2 from the outer side surface, and the middle portion of the inner side surface of the buffer member 115'' has a thickness between T2 and T1 (>T2).

[0484] In Figure 40 (c) thereof, at least a part (upper and lower ends) of the buffer member 115'' satisfies the minimum thickness T2, and the thickness of the middle portion of the buffer member 115'' has a thickness T1 greater than the minimum thickness T2. As described above, since the thickness T1 of the middle portion of the buffer member 115'' is thicker than T2, it has an advantage of being easier to manufacture than the existing buffer member 115' in Figure 40 (a) thereof.

[0485] Referring to Figure 40 (b) thereof, due to the curved surface portion 121c of the ferrite core 121, the inner side surface of the buffer member 115 is formed by a curved surface. The upper and lower ends of the inner side surface of the buffer member 115 have a thickness T3 (<T2) with respect to the outer side surface of the buffer member 115, and the middle portion of the inner side surface of the buffer member 115 has a thickness between T3 and T2 with respect to the outer side surface of the buffer member 115.

[0486] In Figure 40 (b) thereof, although the minimum thickness T2 cannot be satisfied at the upper and lower ends of the buffer member 115, the minimum thickness T2 is satisfied at the middle portion of the buffer member 115, so the buffer member 115 can be manufactured. Since the buffer member 115 manufactured in this way has a thinner minimum thickness than the buffer members 115' and 115'' shown in Figure 40 (a) and (c) thereof, the volume of the buffer member 115 can be reduced more. Therefore, the buffer member 115 can be arranged further downward inside the tapered portion 101t of the housing 101, and thus the ferrite core 121 can be arranged at a more downward predetermined height S than Figure 40 (a) thereof, Figure 40 (c) thereof.

[0487] Figure 41 is a diagram for explaining the amount of increase in the size of the pen signal at the predetermined height S shown in Figure 40 (a) to (c) thereof.

[0488] Referring to Figure 41 the table shown therein, it can be confirmed that the larger the predetermined height S is, the larger the size of the pen signal received by the receiver side becomes.

[0489] As described above, Figures 37 to 40The illustrated stylus 100 according to an embodiment of the present invention features a tapered portion of the ferrite core 121 in the inductor section 120 with a different configuration from that of conventional ferrite cores 131'. This allows for a reduction in the thickness of the buffer member 115, enabling the ferrite core 121 to be positioned closer to the end of the core 102 inside the housing 101. Consequently, the receiver side receiving the pen signal emitted from the stylus 100 according to an embodiment of the present invention can obtain a larger pen signal, thus improving the sensing sensitivity of the stylus at the receiver side.

[0490] On the other hand, the receiver mentioned above refers to a module or device that receives pen signals emitted from a stylus 100 according to an embodiment of the present invention. The receiver can be a general digitizer or a display panel. The display panel may have at least one annular pattern of conductive material. This annular pattern may be integrated with a touch sensor or may be integrated with the display panel independently of the touch sensor.

[0491] The following description uses the attached figures. Figures 37 to 40 The illustration shows the specific internal structure of a stylus 100 according to an embodiment of the present invention, including the ferrite core 121 and the buffer component 115.

[0492] Figure 42 yes Figure 36 The illustration shows a cross-sectional view of a portion of a stylus 100 according to one embodiment of the present invention. Figure 43 (a) is used to explain Figure 42 The figure shows a perspective view of the structure of the inner housing 110 and the buffer component 115. Figure 43 (b) is a perspective view of only the inner shell 110. Figure 44 It was removed Figure 43 (a) is a perspective view of the internal casing 110 shown in the figure. Figure 45 (a) and (b) are observations from multiple perspectives. Figure 42 and Figure 44 The figure shows a perspective view of the first fixing component 130. Figure 46 (a) and (b) are observations from multiple perspectives. Figure 42 and Figure 44 The diagram shows a perspective view of the movable part 170. Figure 47 (a) and (b) are observations from multiple perspectives. Figure 42 and Figure 44 The figure shows a perspective view of the second fixing component 190. Figure 48 Viewed from one side Figure 42 and Figure 44 The diagram shows a three-dimensional representation composed of the parts depicted. Figure 49 (a) and (b) are Figure 42 and Figure 44 The diagram shows only a portion of the three-dimensional composition.

[0493] Reference Figure 42 The stylus 100 includes at least two of the following: an inner housing 110, a buffer component 115, an inductor portion 120, a capacitor portion (not shown), a first fixing component 130, a magnet 140, a cover component 150, a ring terminal 161, contact terminals 165a and 165b, a moving component 170, a first elastic component 180, a second elastic component 185, an elastic body 155, a second fixing component 190, and a substrate 210.

[0494] The inner housing 110 is made of a non-conductive material and is disposed inside the outer housing 101. Specifically, the inner housing 110 may be disposed inside the first outer housing 101a of the outer housing 101. The inner housing 110 may have a shape that surrounds the inductor portion 120, the first fixing member 130, the ferrite chip 140, the cover member 150, the ring terminal 161, the contact terminals 165a and 165b, the moving member 170, the first elastic member 180, the second elastic member 185, the elastic body 155, and the second fixing member 190. The inner housing 110 may serve to protect the various components disposed inside from physical and / or electrical shocks.

[0495] Reference Figure 42 and Figure 43 In (a) and (b), the inner housing 110 may have a first opening 111 disposed between a first protrusion 131 of a first fixing member 130 and a first protrusion 192 of a second fixing member 190. The first opening 111 may have a base groove 111b extending along the length direction of the stylus 100 and a plurality of extension grooves 111e connected to the base groove 111b and extending in a direction perpendicular to the length direction of the base groove 111b. The plurality of extension grooves 111e may be formed at positions corresponding to the plurality of first protrusions 131, 192. As an example, the first opening 111 may have an 'E' shape.

[0496] The multiple first protrusions 131 and 192 can be arranged from the multiple extension slots 111e to the base slot 111b, or from the base slot 111b to the multiple extension slots 111e, by rotating the inner housing 110 counterclockwise or clockwise about the core 102 as the axis of rotation. In particular, the positions of the first fixing member 130 and the second fixing member 190 inside the inner housing 110 can be fixed by arranging the multiple first protrusions 131 and 192 from the base slot 111b to the multiple extension slots 111e. On the other hand, the moving member 170 is not directly coupled to the inner housing 110, so it can move in conjunction with the linear reciprocating motion of the core 102 caused by external force between the first fixing member 130 and the second fixing member 190.

[0497] The inner housing 110 may have a second opening 113 for arranging the extension coils 125a and 125b and exposing the access terminals 165a and 165b. The second opening 113 provides space for arranging the extension coils 125a and 125b and can protect the extension coils 125a and 125b from external impacts. In addition, the installation position of the access terminals 165a and 165b can be easily identified through the second opening 113.

[0498] A buffer member 115 can be disposed between the inductor 120 and the housing 101, and between the core 102 and the inner housing 110. The buffer member 115 has a through hole through the core 102. This buffer member 115 can guide the position of the core 102, stably fix the inductor portion 120, and block external electrical or magnetic influences on the inductor portion 120. This buffer member 115 can be constructed independently of the inner housing 110, but is not limited thereto; the buffer member 115 can also be integrally constructed with the inner housing 110.

[0499] Reference Figure 42 and Figure 44 A buffer member 115, an inductor section 120, a first fixing member 130, a moving member 170, and a second fixing member 190 can be sequentially arranged from one end of the core 102 along the length direction of the stylus 100 (hereinafter referred to as the 'length direction'). That is, along the length direction, the inductor section 120 can be arranged on the buffer member 115, the first fixing member 130 can be arranged on the inductor section 120, the moving member 170 can be arranged on the first fixing member 130, and the second fixing member 190 can be arranged on the moving member 170.

[0500] The inductor section 120 includes a ferrite core 121 and a coil section 123 wound around the ferrite core 121. The ferrite core 121 has a through-hole through which a core 102 passes. Through this through-hole, the core 102 can reciprocate linearly along the length direction. The coil section 123 may be wound in at least one layer around the ferrite core 123. Extension coils 125a and 125b may be connected to both ends of the coil section 123, respectively. The extension coils 125a and 125b can extend along the length direction and are connected to coil electrodes 213a and 213b disposed on the substrate 210, respectively.

[0501] The inductor section 120 is fixedly disposed inside the housing 101. The inductor section 120 can be fixed between the first fixing member 130 and the buffer member 115 in the longitudinal direction. The inductor section 120 can be fixed by the inner housing 110 in a direction perpendicular to the longitudinal direction (hereinafter referred to as the 'vertical direction').

[0502] The inductor section 120 can be fixedly disposed on one side of the first fixing member 130. A portion of the inductor section 120 can be disposed in the second cavity 133b of the first fixing member 130.

[0503] The inductor section 120 can be electrically connected to a capacitor section (not shown) mounted on the substrate 210 to form a resonant circuit section. The resonant frequency can be set by the inductance L value of the inductor section 120 and the capacitance C value of the capacitor section (not shown). The inductance L value of the inductor section 120 changes with the movement of the magnet 140, so the resonant frequency is variable.

[0504] A capacitor section (not shown) is disposed on the substrate 210. It has a preset capacitance value C. The capacitor section (not shown) may include two or more capacitors. At least one of the two or more capacitors is a basic capacitor, which can form a circuit in a state where it is always electrically connected to the inductor section 120.

[0505] The capacitor section (not shown) includes a jumping capacitor 215. The jumping capacitor 215 is mounted on the substrate 210 and can form a circuit electrically connected to the access terminals 165a and 165b. For example, the jumping capacitor 215 can be electrically connected to the access pads 211a and 211b disposed on the substrate 210 via conductive patterns 212a and 212b. The jumping capacitor 215 can be electrically connected to or disconnected from the base capacitor as the core 102 moves. When the core 102 is not subjected to external force, the annular terminal 161 contacts the access terminals 165a and 165b, thus the jumping capacitor 215 is electrically connected to the base capacitor. Conversely, when the core 102 is subjected to external force causing the moving member 170 linked to the core 12 to move towards the first elastic member 180, the annular terminal 161 separates from the access terminals 165a and 165b, at which point the jumping capacitor 215 can be electrically disconnected from the base capacitor.

[0506] Reference Figure 42 , Figure 44 , Figure 45 In (a) and (b), the first fixing member 130 is disposed inside the inner housing 110. The first fixing member 130 is generally cylindrical. The first fixing member 130 has a first cavity 133a and a second cavity 133b. The first cavity 133a is disposed... Figure 42 The magnet 140 shown in the figure is configured in the second cavity 133b. Figure 42 The diagram shows one end of the ferrite core 121 of the inductor section 120. A partition 132 is disposed between the first cavity 133a and the second cavity 133b, the partition 132 having a through hole 132h through which the core 102 passes.

[0507] An inductor portion 120 is disposed on one side of the first fixing member 130, and a second fixing member 190 is disposed at a position spaced apart from the other side of the first fixing member 130.

[0508] Multiple first protrusions 131, as described above, may be provided on the outer side of the first fixing member 130.

[0509] The outer surface of the first fixing member 130 may be formed with a plurality of first grooves 135 for the plurality of extensions 171 of the moving member 170 to be respectively disposed. Additionally, the outer surface of the first fixing member 130 may be formed with grooves formed along the length direction such that they are aligned with the moving member 170. Figure 44 The extended coils 125a and 125b shown in the diagram maintain a certain interval in the second slot 137.

[0510] Reference Figure 42 , Figure 44 , Figure 46In (a) and (b), the moving part 170 is disposed between the first fixed part 130 and the second fixed part 190. The moving part 170 can be linked with the movement of the core 102 in the length direction to reciprocate linearly between the first fixed part 130 and the second fixed part 190.

[0511] The first fixing component 130 and the second fixing component 190 can also be referred to as fixing parts.

[0512] The movable component 170 is disposed inside the inner housing 110. The movable component 170 is generally cylindrical. The movable component 170 has a first cavity 173a and a second cavity 173b. The first cavity 173a is configured with... Figure 42 A portion of the first elastic member 180 shown in the figure is configured in the second cavity 173b. Figure 42 A portion of the cover component 150 is shown in the figure. A partition 172 is disposed between the first cavity 173a and the second cavity 173b, and the partition 172 is disposed between the cover component 150 and the first elastic component 180. Here, the movable component 170 may also be referred to as a movable part.

[0513] Multiple extensions 171 of multiple first slots 135 of the first fixed member 130 are disposed on the outer surface of the movable member 170. The multiple extensions 171 have a shape that extends along the length direction and are movable along the first slots 135 of the first fixed member 130.

[0514] The outer surface of the moving part 170 may be formed with a feature for... Figure 47 The second extension 193 of the second fixing member shown in the figure is respectively configured with a plurality of second slots 175. As the moving member 170 reciprocates linearly along the length direction, the second slots 175 also move together, so the position of the second extension 193 of the second fixing member 190 configured in the second slot 175 can be changed.

[0515] The second groove 175 of the moving member 170 may have a shape corresponding to the second extension 193 of the second fixing member 190. The second groove 175 may have a shape that prevents the second extension 193 of the second fixing member 190 from completely disengaging from the second groove 175 when the moving member 170 moves away from the second fixing member 190. For this purpose, the second groove 175 may have a shape in which the width of the second groove 175 becomes narrower the closer it is to the side of the second fixing member 190, and the second extension 193 of the second fixing member 190 may have a shape that protrudes in the width direction of the second groove 175.

[0516] A first groove 177 may be formed on the outer surface of the movable component 170. The first groove 177 is elongated along the length direction, such as... Figure 49As shown in diagram (b), access terminals 165a and 165b can be configured in the first slot 177. The first slot 177 can be used to fix and guide the position of access terminals 165a and 165b. In addition, the first extension 192 of the second fixing member 190 can be configured together with the access terminals 165a and 165b in the first slot 177.

[0517] The movable component 175 is disposed between the first fixed component 130 and the second fixed component 190. The extension 171 of the movable component 170 is disposed in the first groove 135 of the first fixed component 130. The first extension 199 and the second extension 193 of the second fixed component 190 are disposed in the first groove 175 and the second groove 177 of the movable component 170. Therefore, it has the advantage that the movable component 175 will not detach outward even when it moves frequently.

[0518] The movable component 170 includes a surface 179 on which a first cavity 173a is disposed, and the surface 179 may be configured with Figure 42 and Figure 48 The annular terminal 161 is shown in the figure. The shape of one side 179 can correspond to the shape of the annular terminal 161. The annular terminal 161 disposed on one side 179 can be guided by the inner side of one or more extensions 171 disposed on the periphery.

[0519] Reference Figure 42 , Figure 44 and Figure 47 The second fixing member 190 is fixedly disposed inside the housing 101. At least a portion of the second fixing member 190 is fixedly disposed inside the inner housing 110.

[0520] The second fixing member 190 includes a cylindrical base 191. One side 191a of the base 191 has a mounting surface for configuration. Figure 42 The cavity 195 is a portion of the first elastic member 180 shown in the figure. It is disposed on one side 191a of the base 191. Figure 42 The second elastic component 185 is shown in the figure.

[0521] The second fixing member 190 includes a first extension 199 and a second extension 193 extending from one side 191a of the base 191 toward the moving member 170. Multiple first extensions 199 and second extensions 193 can be arranged on one side 191a of the base 191. Specifically, two first extensions 199 can be configured opposite each other, and two second extensions 193 can be configured opposite each other. Multiple first extensions 199 and second extensions 193 can be guided from four directions. Figure 42 The figure shows the outer side of the second elastic member 185. Therefore, the position of the second elastic member 185 can be fixed by a plurality of first extensions 199 and second extensions 193.

[0522] The inner side of the first extension 199 guides the outer side of the second elastic member 185, and the outer side of the first extension 199 can support... Figure 42 and Figure 44 Part of the access terminals 165a and 165b shown in the diagram.

[0523] The second extension 193 may have a predetermined shape to prevent disengagement from the second groove 175 after engagement with the moving member 170. For example, the second extension 193 may have a shape in which at least a portion protrudes, thus preventing disengagement from the second groove 175.

[0524] The second fixing member 190 may have a groove 194 formed on the outer surface of the base 191. The surface of the groove 194 may be connected to the outer surface of the first extension 199 without any additional step. A fixture may be disposed in the groove 194. Figure 42 and Figure 44 Part of the access terminals 165a and 165b shown in the diagram.

[0525] The second fixing member 190 may include a mounting portion 196 extending along the length direction from the other side (not shown) of the base 191. The mounting portion 196 may have… Figure 42 and Figure 44 The cavity 197 is configured on the substrate 210 shown in the figure.

[0526] The second fixing component 190 may have features for securing... Figure 42 and Figure 44 The access terminals 165a and 165b shown in the figure are connected to the opening 198 of the substrate 210 disposed in the cavity 197. The other end of the access terminals 165a and 165b can be disposed in the opening 198 to connect to the access pads 211a and 211b of the substrate 210.

[0527] Reference Figure 42 , Figure 44 , Figure 48 , Figure 49 In (a) and (b), the core 102 extends along the length direction to a predetermined length, and one end may have a sharp shape. This one end protrudes outside the outer casing 101.

[0528] The core 102 includes a step portion 102T disposed in a portion of the intermediate section between one end and the other end. The thicknesses of the one end and the other end of the intermediate section can be different, based on the step portion 102T. The first thickness D1 of the one end of the intermediate section, based on the step portion 102T, can be made thicker than the second thickness D2 of the other end of the intermediate section. With this configuration of the step portion 102T, the magnet 140 can be moved along with the core 102 when it moves in the longitudinal direction by an external force. That is, when the core 102 moves, the step portion 102T pushes against one side of the magnet 140. The magnet 140 can be moved in the longitudinal direction. As the magnet 140 moves along the longitudinal direction, the distance between the inductor section 120 and the magnet 140 changes. This change in distance alters the inductance L value of the inductor section 120, and the change in inductance value changes the resonant frequency of the stylus 100. The stylus sensing device that interacts with the stylus 100 can detect the pen pressure (pressure) acting on the core 102 by sensing the change in the resonant frequency.

[0529] Magnet 140 is arranged in Figure 45 The first cavity 133a of the first fixing component 130 shown in the figure has a cylindrical shape. Furthermore, the magnet 140 has a through hole through a portion of the core 102. The diameter of the through hole can be greater than or equal to the second thickness D2 and less than the first thickness D1.

[0530] Magnet 140 can be a ferrite chip.

[0531] The magnet 140 can move in conjunction with the core 102 in a linear reciprocating motion along the length direction. Because the magnet 140 moves in conjunction with the core 102, the inductance L value of the inductor section 120 can change.

[0532] A cover member 150 is disposed at the other end of the core 102. The cover member 150 may have a shape that covers the other end of the core 102. For example, the cover member 150 may have a cylindrical shape with different thicknesses at the top and bottom.

[0533] An elastic body 155 may be disposed between the cover component 150 and the magnet 140. The elastic body 155 may be a spring. It may be configured such that one end of the elastic body 155 is fitted onto a portion of the cover component 150, and the other end of the elastic body 155 abuts against the magnet 140.

[0534] The elastic body 155 can be a component used to correct deviations in the magnet 140. For example, if the length or height of the magnet 140 is 0.1 mm smaller than the specification, the elastic body 155 will press the magnet 140 against the partition 132 of the first fixing member 130.

[0535] The annular terminal 161 is a hollow circle that electrically connects to two access terminals 165a and 165b. The shape of the annular terminal 161 is not limited to a circle; it can also be polygonal.

[0536] The annular terminal 161 is disposed on one side of the moving member 170 and moves in conjunction with the moving member 170. That is, it moves together with the moving member 170 in the linear reciprocating motion along the length direction.

[0537] The access terminals 165a and 165b include a side portion that contacts or separates from the annular terminal 161 and a other side portion that is connected to the substrate 210. The side portion can contact or separate from the annular terminal 161 by moving the annular terminal 161, which is linked to the moving member 170. The other side portion is directly connected to the substrate 210 by welding or the like. Figure 42 The substrate 210 shown in the figure has access pads 211a and 211b.

[0538] Access terminals 165a and 165b include a base disposed between one side and the other side. The base may have a shape extending in the length direction. The base is disposed on... Figure 46 The movable part 170 shown in the figure is disposed in the first slot 177. Figure 47 The second fixing member 190 shown in the figure is located in the groove 194 and can be guided by the first extension 199 of the second fixing member 190.

[0539] The first elastic member 180 is disposed within the second fixed member 190. The first elastic member 180 may have a cylindrical shape that is elongated along the length direction. The first elastic member 180 may be made of rubber.

[0540] The first elastic member 180 may be disposed at one end of Figure 47 The cavity 195 of the second fixing member 190 shown in the figure has its other end disposed in... Figure 46 The first cavity 173a of the movable component 170 shown in the figure.

[0541] The second elastic member 185 is disposed within the second fixed member 190. The second elastic member 185 may have a flat cylindrical shape. The second elastic member 185 may be made of rubber. The second elastic member 185 may be made of a rubber material that is relatively harder than the first elastic member 180. Therefore, the second elastic member 185 is made of hard rubber, while the first elastic member 180 may be made of soft rubber.

[0542] On the other hand, the second elastic member 185 can also be a spring. The second elastic member 185 can be a spring configured to respond to a relatively heavier force compared to the first elastic member 180.

[0543] The second elastic member 185 is thinner in the length direction than the first elastic member 180, and its diameter in the vertical direction is wider than that of the first elastic member 180.

[0544] The second elastic member 185 is configured to surround the middle portion of the first elastic member 180. Therefore, the second elastic member 185 has a through hole through which the first elastic member 180 passes.

[0545] like Figure 49 As shown in Figure (b), the second elastic member 185 may have a groove 185g that fits onto a portion of the first extension 199 of the second fixing member 190. The second elastic member 185 can thus be stably fixed to the second fixing member 190.

[0546] The following is for reference Figure 50 Explanation based on Figures 42 to 49 The figure illustrates the operation of a stylus 100 according to one embodiment.

[0547] Figure 50 (a) through (c) are used to illustrate Figures 42 to 49 The illustration shows the actions of the stylus 100. Specifically, Figure 50 (a) is a diagram showing the hover state H of the stylus 100. Figure 50 (b) is a diagram showing the contact state C of the stylus 100. Figure 50 (c) is a diagram showing the pen pressure P state of the stylus 100.

[0548] Reference Figure 50 In (a), when in the hovering state H, the core 102 is not subjected to any external force, so its internal structure remains unchanged. In particular, the annular terminal 161 and the access terminals 165a and 165b remain in contact with each other.

[0549] Reference Figure 50 In (b), a predetermined pressure is applied to one end of the core 102 in contact state C. The core 102 moves inward toward the inner side of the outer casing 101 due to the applied pressure. As the core 102 moves, the cover member 150 pushes the moving member 170 toward the first elastic member 180, and the annular terminal 161 separates from the access terminals 165a and 165b. Therefore, Figure 42 The electrical connection between the jumping capacitor 215 and the basic capacitor is severed, and the total capacitance of the capacitor section (not shown) decreases. Since the magnet 140 does not move, the inductance value of the inductor section 120 remains unchanged. Because the total capacitance of the capacitor section (not shown) decreases, the resonant frequency changes.

[0550] Reference Figure 50In state (c), under pen pressure P, a greater pressure is applied to one end of the core 102 than in contact state C. Due to this greater pressure, the core 102 moves further inward toward the outer casing 101, thus pushing the magnet 140 by the step portion 102T of the core 102. As the magnet 140 is pushed, the elastic body 155 disposed between the cover member 150 and the magnet 140 is compressed. The first elastic member 180 and the second elastic member 185 are compressed by the movement of the moving member 170. The magnet 140 moves away from the inductor portion 120, thus the inductance L of the inductor portion 120 gradually decreases. The capacitance of the capacitor portion (not shown) remains the same as in contact state C. The decrease in the inductance value of the inductor portion 120 causes a change in the resonant frequency.

[0551] Figure 51 (a) illustrates the example based on Figure 50 The LC value change of the resonant circuit section in operations (a) to (c), Th interval represents Figure 50 The hovering state of (a), where point Tc represents... Figure 50 The contact state of (b), where the Tp interval represents Figure 50 (c) Pen pressure state. Figure 51 (b) is shown Figure 50 The frequency characteristics of each action state from (a) to (c) are plotted.

[0552] Reference Figure 51 In (a), the LC value of the resonant circuit section, composed of a capacitor section (not shown) and an inductor section 120, remains at a certain value before the core 102 of the stylus 100 contacts the touch surface (Th), and decreases sharply immediately after the core 102 contacts the touch surface (Tc). Furthermore, during the period Tp in which the stylus 100 is subjected to pen pressure after contact with the touch surface, the LC value of the resonant circuit section decreases further with increasing pen pressure. That is, within this period Tp, as the pen pressure applied to the stylus 100 increases, the LC value of the resonant circuit section can gradually decrease. (Refer to...) Figure 51 In (a), the LC value of the resonant circuit exhibits the following order: hover state > contact state > pen pressure state. Furthermore, compared to the state where the pen pressure gradually increases, the change in LC value is greater immediately after the core 102 contacts the touch surface.

[0553] When the inductance value of the inductor section 120 and the capacitance value of the capacitor section (not shown) are changed, the resonant frequency and Q value of the resonant circuit section can change. The smaller the inductance of the resonant circuit section, the larger the resonant frequency; the smaller the inductance, the smaller the Q value. Therefore, if... Figure 51As shown in Figure (b), for the frequency characteristics of the resonant signal Vpen output from the resonant circuit section, the greater the moving distance of the core 102, that is, the greater the pen pressure, the greater the resonant frequency can be (hover state < contact state < pen pressure state), and the smaller the Q value (hover state > contact state > pen pressure state).

[0554] When the resonant frequency of the resonant circuit changes, the phase of the electromagnetic signal output from the stylus 100 changes. Based on this phase change, the stylus sensing device that interacts with the stylus 100 can calculate the change in the LC value of the resonant circuit, and thereby detect whether the stylus 100 is in contact with the stylus sensing device and the pen pressure.

[0555] As mentioned above, according to Figures 42 to 49 The stylus 100 in one embodiment of the illustration changes at least one or both of the inductance and capacitance values ​​of the resonant circuit, thus enabling the stylus sensing device to detect pen pressure. Furthermore, it has the advantage of being able to detect precise pen pressure.

[0556] On the other hand, according to Figures 42 to 49 The stylus of one embodiment illustrated may experience assembly deviations during assembly. These assembly deviations can cause predetermined problems, as described below. Figures 52 to 54 Detailed explanation.

[0557] Figure 52 (a) through (c) are used to explain the assembly Figures 42 to 50 The diagram illustrates the problem caused by assembly deviation of the core 102 when using the stylus 100.

[0558] Specifically, Figure 52 (a) shows the core 102 installed correctly according to the pre-design without any assembly deviation. Figure 52 (b) and Figure 52 (c) shows a situation where an assembly deviation occurs during the assembly process, resulting in the core 102 failing to be installed in the pre-designed position.

[0559] exist Figure 52 In (a), the step portion 102T of the core 102 is located in the through hole 132h of the partition 132 formed in the first fixing member 130. The position of this step portion 102T is normal and without deviation during assembly. Conversely, in Figure 52 Assembly deviations in (b) and (c) result in the step portion 102T being positioned elsewhere instead of the through hole 132h of the partition 132. Specifically, in Figure 52 (b) The middle section 102T is disposed in the second cavity 133b of the first fixing member 130 disposed in the inductor section 120 (refer to) Figure 45 (b)), in Figure 52(c) The intermediate section 102T is disposed in the first cavity 133a of the first fixing member 130 disposed in the magnet 140 (refer to) Figure 45 (a)

[0560] Assembly deviation occurred Figure 52 In case (b), even Figure 50 Following the contact state of (b), pressure is continuously applied to the core 102. Since the distance between the inductor section 120 and the magnet 140 remains constant, the inductance value of the inductor section 120 does not change immediately. On the other hand, Figure 52 In case (c), the magnet 140 passes through the core 102 in Figure 50 (a) hovering state and Figure 50 The inductance value of the inductor section 120 can change as the contact state of (b) moves between them.

[0561] for Figure 52 For each of (a) to (c), refer to Figure 53 This explains the change in resonant frequency based on the pressure applied to the core 102.

[0562] exist Figure 53 In the curve diagram, line ①, which indicates no assembly deviation, corresponds to... Figure 52 (a), line ② with assembly deviation corresponds to Figure 52 (c), line ③ with assembly deviation corresponds to Figure 52 (b)

[0563] Reference Figure 53 In case ③, even if the pressure increases immediately after the core 102 enters the contact state, there is no change in the resonant frequency. The stylus sensing device interacting with the stylus 100 cannot sense the pen pressure applied to the core 102. In case ②, the resonant frequency still changes when the core 102 is in a hovering state, therefore the stylus sensing device will recognize the core 102 as being in a contact state rather than a hovering state. As above, Figure 52 Assembly deviations in (b) and (c) may cause the stylus sensing device to have difficulty accurately sensing the stylus 100.

[0564] Figure 54 (a) through (c) are used to explain the assembly Figures 42 to 50 The diagram illustrates a problem caused by assembly deviations in terminals 165a and 165b when the stylus 100 is connected.

[0565] Specifically, Figure 54 (a) shows the connection terminals 165a and 165b installed according to the pre-design without assembly deviation. Figure 54 (b) and Figure 54(c) shows a diagram where assembly deviations during the assembly process resulted in the access terminals 165a and 165b failing to be installed in the pre-designed positions.

[0566] exist Figure 54 In (a), one end 165a1 of the access terminal 165a is disposed abutting against the annular terminal 161, and the other end 165a2 is disposed abutting against the access pad 211a of the substrate 210. The position of this access terminal 165a is correctly assembled without deviation. Conversely, in Figure 54 Assembly deviations in (b) and (c) of the access terminal 165a result in it being configured in an alternate location instead of the pre-designed location. Specifically, in Figure 54 In (b), the access terminal 165a is offset by a predetermined distance toward the substrate 210, so that one end 165a1 presses the annular terminal 161 with considerable force. Figure 54 In (c), the access terminal 165a is offset by a predetermined distance toward the first fixing member 130, so that one end 165a1 is separated from the annular terminal 161 by a predetermined distance.

[0567] Assembly deviation occurred Figure 54 In case (b), the access terminal 165a and the ring terminal 161 are assembled in a mutually pressed state, thus providing a basis for identification. Figure 50 The problem of increased pressure in the contact state of (b). On the other hand, in Figure 54 In case (c), from Figure 50 In the hovering state of (a), the annular terminal 161 and the access terminal 165a are separated, so even if the core 102 is subjected to pressure, the stylus sensing device cannot detect it. Figure 50 The contact state of (b).

[0568] the following Figures 55 to 59 This indicates that even if a reference occurs Figures 52 to 54 The assembly deviations described have little impact on performance, and the stylus can be improved by reducing internal components to save manufacturing costs according to other embodiments.

[0569] and Figures 42 to 50 Compared to the stylus 100 shown in the illustration, in Figure 55 In the stylus shown in the diagram, 1) the first elastic component 180' is made of a spring instead of rubber, and (2) the [unclear text] is omitted. Figures 42 to 50 The diagram illustrates the configuration of the stylus 100, including the annular terminal 161, input terminals 165a and 165b, the jumper capacitor 215, and the electrical connections for them. The remaining configuration is similar to... Figures 42 to 50 The stylus 100 shown in the illustration has the same structure, so the above description will be used instead of the specific description. The following is a detailed explanation of the differences in structure.

[0570] Reference Figure 55 The first elastic member 180' is composed of a spring. The first elastic member 180' can be configured to be compressed from a low pressure (e.g., about 10 gf), and because the compression strength is weak, it can be compressed quickly even with a small increase in pressure.

[0571] Figure 56 (a) and (b) are used to illustrate Figure 55 The diagram shows the first elastic component 180'. Figure 56 (a) shows what the first elastic member 180' looks like when no force is applied. Figure 56 (b) shows the first elastic member 180' disposed in Figure 55 The diagram shows the relationship between the moving part 170 and the second fixed part 190.

[0572] like Figure 56 As shown in diagram (b), the first elastic member 180' is fitted between the moving member 170 and the second fixed member 190, and can be configured in a partially compressed (or incompletely compressed) state. The first elastic member 180' is not compressed unless a force (or repulsive force) greater than the amount of compression by the moving member 170 and the fixed member 190 is applied. This force (or repulsive force) can, for example, be around 10 gf. Conversely, the second elastic member 190 is compressed when subjected to a force greater than the amount of compression by the moving member 170.

[0573] The following <Mathematical Formula 1> shows the force (or repulsive force) F of the partially compressed first elastic member 180'.

[0574]

[0576] In the above <Mathematical Formula 1>, G represents the lateral elastic modulus of the spring, Na represents the effective number of windings of the spring, D represents the diameter of the spring, d represents the diameter of the wire, and x represents the length of the spring in compression (-direction).

[0577] On the other hand, the first elastic member 180' can also be configured between the moving member 170 and the second fixed member 190 in an uncompressed state. Therefore, the stylus according to another embodiment of the present invention is not limited to being configured between the moving member 170 and the second fixed member 190 in a compressed state.

[0578] The first elastic member 180' can be configured to respond to a relatively larger weight compared to the elastomer 155.

[0579] The following is for reference Figure 57 illustrate Figures 55 to 56 The illustration shows the operation of a stylus according to other embodiments.

[0580] Figure 57 (a) through (c) are used to illustrate Figures 55 to 56 The illustration shows the actions of a stylus. Specifically, Figure 57 (a) is a diagram showing the hover state H of the stylus. Figure 57 (b) is a diagram showing the contact state C of the stylus. Figure 57 (c) is a diagram showing the pen pressure P state of the stylus.

[0581] Reference Figure 57 In (a), the core 102 is not subjected to any external force in the hovering state H, so the internal structure remains unchanged.

[0582] Reference Figure 57 In (b), under contact state C, one end of the core 102 is subjected to a predetermined pressure. Due to the applied pressure, the core 102 moves inward toward the inner side of the outer casing 101. As the core 102 moves, the cover member 150 pushes the moving member 170 toward the first elastic member 180', thus pushing the moving member 170 toward the second elastic member 185. In this state, the first elastic member 180' undergoes compression equivalent to the amount of pushing the moving member 170. Furthermore, as the core 102 moves, the step portion 102T of the core 102 pushes the magnet 140 toward the first elastic member 180'. As the magnet 140 is pushed, the distance between the inductor portion 120 and the magnet 140 changes, altering the inductance value of the inductor portion 120 and ultimately changing the resonant frequency.

[0583] Reference Figure 57 In state (c), under pen pressure P, one end of the core 102 experiences a greater pressure than under contact state C. This greater pressure causes the core 102 to move further inward toward the outer casing 101, thus moving the magnet 140 further away from the inductor section 120. As the magnet 140 is pushed, the elastic body 155 disposed between the cover member 150 and the magnet 140 is compressed. The movement of the moving member 170 causes the first elastic member 180' to be further compressed, and the second elastic member 185 is also compressed. Since the magnet 140 is further away from the inductor section 120, the inductance L of the inductor section 120 gradually decreases. Because the inductance of the inductor section 120 decreases, the resonant frequency changes.

[0584] Figure 58 Figures (a) and (b) are examples illustrating assembly deviations in core 102. Figure 59 Yes Figure 58Each of (a) and (b) shows a graph of the change in resonant frequency caused by the pressure applied to the core 102.

[0585] Figure 58 Figure (a) shows the step portion 102T of the core 102 shifting towards the magnet 140 due to assembly deviations during the assembly process, and is positioned almost against one side of the magnet 140. Figure 58 (b) is a diagram showing that the step portion 102T of the core 102 shifts toward the inductor portion 120 due to assembly deviation.

[0586] exist Figure 59 In the curve graph, line ① represents the case where no assembly deviation occurs, corresponding to... Figure 55 Line ② corresponds to Figure 58 (a), line ③ corresponds to Figure 58 (b)

[0587] Reference Figure 59 For a stylus according to another embodiment of the invention, including a first elastic member 180', even if the core 102 has a slight assembly deviation, the performance change is small compared to the case without assembly deviation. Therefore, it has a higher performance than... Figure 42 The illustrated stylus 100 has the advantage of being more conducive to mass production.

[0588] in addition, Figures 55 to 57 The stylus shown in the image is not in use. Figures 42 to 49 The stylus 100 shown in the diagram, including components such as the jumping capacitor 215, the ring terminal 161, and the access terminals 165a and 165b, can be configured with a simple internal structure, further reducing manufacturing costs.

Figure 42 In the illustrated stylus 100, the first elastic component 180 is replaced with Figure 55 and Figure 56 The first elastic component 180' shown in the figure.

[0590] On the other hand, although no other diagram was used, Figure 37 The ferrite core 121 and buffer component 115 shown in the figure can be used not only for Figures 42 to 59 The stylus described can also be used directly with other existing styluses.

[0591] Figure 60It is based on Figures 37 to 38 The illustration shows a perspective view of a modified example of the ferrite core 121. Figure 61 (a) is Figure 60 The diagram shows a magnified front view of a portion of the ferrite core 121'. Figure 61 (b) is Figure 61 A cross-sectional view of (a) towards A-A'.

[0592] Reference Figures 60 to 61 The ferrite core 121' has a cylindrical shape. A planar portion 121d may be disposed on at least a portion of the outer surface of the ferrite core 121'. Another portion of the outer surface of the ferrite core 121' may also be disposed with a planar portion corresponding to the planar portion 121d. Through the planar portion 121d, the ferrite core 121' can be stably disposed inside the housing.

[0593] The ferrite core 121' has a cylindrical upper end portion 121a' and a lower end portion 121b', and the lower end portion 121b' may have at least two or more curved surfaces 121c'. The curved surfaces 121c' may be portions that bend from the outside of the lower end portion 121b' to a portion adjacent to the through hole 121h of the ferrite core 121'. These curved surfaces 121c' may be respectively arranged on opposite sides of the lower end portion 121b' with reference to the through hole 121h.

[0594] Figures 37 to 38 The curved portion 121c of the ferrite core 121 shown in the figure can be disposed on the entire outside of the lower end 121b', but Figures 60 to 61 The curved portion 121c' of the ferrite core 121' can be configured on the outside of the lower end 121b'.

[0595] The planar portion 121d can be disposed on the upper end portion 121a' and the lower end portion 121b' respectively, and they can be connected to each other for continuous arrangement. Among them, the planar portion 121d disposed on the lower end portion 121b' can be disposed on the outside of the lower end portion 121b' between two curved surfaces 121c' that are arranged opposite each other.

[0596] Figures 60 to 61 The ferrite core 121' shown in the diagram can be used instead of... Figures 42 to 59 The stylus shown in the illustration. In this case, the buffer (not shown) may have a shape that covers a portion of the lower end 121b' of the ferrite core 121'.

[0597] Figure 62 Is adopted Figure 37 The illustration shows a cross-sectional view of a stylus for another variation of the ferrite core 121. Figure 63 Is only shown Figure 62The diagram shows a cross-sectional view of the ferrite core 121'' and the coil section 123. Figure 64 yes Figures 62 to 63 The diagram shows a 3D view of the ferrite core 121''. Figure 65 (a) is Figure 64 The diagram shows a magnified front view of a portion of the ferrite core 121''. Figure 65 (b) is towards Figure 64 (a) B-B' cross section.

[0598] Reference Figures 62 to 64 According to other variations, the ferrite core 121'' includes an upper end 121a'' and a lower end 121b''.

[0599] The lower end portion 121b'' has a conical shape, and the outer side of the lower end portion 121b'' includes at least one step portion 121c'''.

[0600] The step portion 121c'' can be disposed on the entire outside of the lower end portion 121b'', or as... Figures 64 to 65 It is configured on one or more parts of the outside.

[0601] The step portion 121c'' may include a first surface 121c1, a second surface 121c2 connected to the first surface 121c1, and a third surface 121c3 connected to the second surface 121c2. The first surface 121c1 may be a surface perpendicular to the through-hole 121h, and the third surface 121c3 may be a surface parallel to the through-hole 121h. The second surface 121c2 may connect the first surface 121c1 and the third surface 121c3. Although not shown in a separate figure, the second surface 121c2 may also be a curved surface that curves inward or outward.

[0602] The ferrite core 121'' has a cylindrical shape. A planar portion 121d may be disposed on at least a portion of the outer surface of the ferrite core 121''. Another portion of the outer surface of the ferrite core 121'' may also be disposed with a planar portion corresponding to the planar portion 121d. Through the planar portion 121d, the ferrite core 121'' can be stably disposed inside the housing.

[0603] The planar portion 121d can be disposed on the upper end portion 121a'' and the lower end portion 121b'' respectively, and they can be connected to each other for continuous arrangement. Among them, the planar portion 121d disposed on the lower end portion 121b'' can be disposed between two step portions 121c'' disposed opposite each other on the outside of the lower end portion 121b''.

[0604] Figures 62 to 65 The illustrated ferrite core 121'' includes a step portion 121c'', and therefore can have the same... Figures 37 to 38The ferrite core 121 shown in the figure has almost the same or similar effect.

[0605] Figures 62 to 65 The ferrite core 121'' shown in the diagram can also be used as a substitute for... Figures 42 to 59 The stylus shown in the illustration. In this case, the buffer component (not shown) may have a shape that can cover a portion of the lower end 121b'' of the ferrite core 121''.

[0606] Figure 66 This is a perspective view of a stylus 1000 according to another embodiment of the present invention. Figure 67 yes Figure 66 The illustration shows a cross-sectional view of a portion of the stylus 1000. Figure 68 It was removed Figure 66 The illustration shows a 3D view of the casing 1010 of the stylus 1000.

[0607] Reference Figures 66 to 68 The outer casing 1010 forms the appearance of the stylus 1000. The interior of the outer casing 1010 has a predetermined space and is elongated in one direction. The outer casing 1010 can be composed of two or more parts joined together, or it can be formed as a single piece.

[0608] The outer casing 1010 may be made of a non-conductive synthetic resin material.

[0609] A button section 1090 may be provided on the housing 1010. The button section 1090 may be for performing specific actions of the stylus 1000. For example, it may be a button for canceling an action or performing a special function.

[0610] The core 1020 includes one end disposed outside the housing 1010, and the remaining portion other than the one end disposed inside the housing 1010. The one end of the core 1020 may also be named a pen tip.

[0611] The core 1020 can be made of a non-conductive material.

[0612] The core 1020 may include a base 1021 and an outer contour 1025. The base 1021 has a shape that extends elongated along the length of the stylus 1000. The outer contour 1025 surrounds the side of the base 1021. One end of the base 1021 is exposed rather than covered by the outer contour 1025. The outer contour 1025 is made of a material that is relatively harder than the material of the base 1021, thus reinforcing and protecting the base 1021.

[0613] With the help of an external force, a portion of one end of the core 1020 can move into the housing 1010. The greater the external force, the larger the volume of the portion of the core 1020 inside the housing 1010 can be. When the applied external force decreases, the portion of one end of the core 1020 re-extends out of the housing 1010. When the external force disappears, the portion of one end of the core 1020 returns to its initial state.

[0614] A buffer member 1150 is disposed inside the housing 1010, between one end of the ferrite core 1210 and the inner surface of the housing 1010. The buffer member 1150 may be disposed inside the tapered portion 1010t of the housing 1010. The tapered portion 101t0 of the housing 1010 is the portion of the housing 1010 adjacent to one end of the core 1020, and has a shape where its width or diameter decreases as it approaches one end of the housing 1010.

[0615] The buffer member 1150 has a conical or pyramidal shape and a through hole that extends through one end of the ferrite core 1210 and one end and the other end of the core 1020. The inner surface of the through hole can have a shape corresponding to the outer surface of one end of the ferrite core 1210 and the outer surface of the body portion of the core 1020. The body portion of the core 1020 is the portion of the core 1020 that is elongated in one direction and disposed within the through hole of the ferrite core 1210.

[0616] To provide cushioning between the ferrite core 1210 and the outer casing 1010, the buffer component 1150 can be made of an elastic material such as rubber. This buffer component 1150 can block external electrical or magnetic influences.

[0617] The buffer component 1150 has a shape that surrounds one end of the ferrite core 1210.

[0618] An imaginary tangent that is tangent to both the tapered portion 1010t of the outer casing 1010 and a portion (or pen tip) of the core 1020 disposed outside the outer casing 101 can be as follows: Figure 37 A predetermined angle is formed. Preferably, the predetermined angle is within 30°. When the predetermined angle is within 30°, it has the advantage that the stylus according to other embodiments of the present invention can draw at a 60° angle relative to the contact surface.

[0619] The inductor section 1200 and the capacitor section (not shown) can form an LC resonant section. The resonant frequency can be set by the inductance L value of the inductor section 1200 and the capacitance C value of the capacitor section (not shown). The resonant frequency can vary with the inductance L value of the inductor section 1200 and / or the capacitance C value of the capacitor section (not shown).

[0620] The inductor section 1200 includes a ferrite core 1210 and a coil section 1230 wound around the ferrite core 1210.

[0621] The ferrite core 1210 can have the shape of a cylinder, elliptical cylinder or polygonal cylinder as a whole, and can have a through part 1210h that extends through the interior along the length direction of the ferrite core 1210.

[0622] The ferrite core 1210 has a through portion 1210h through which the main body of the core 1020 is traversed. Through the through portion 1210h, the main body of the core 1020 can reciprocate linearly along its length.

[0623] One end of the ferrite core 1210 may have a tapered shape, with the diameter or width decreasing towards the end portion. The outer surface of the tapered end is as follows: Figure 38 The illustration may include at least one curved surface 121c that curves inward.

[0624] Ferrite core 1210 Figure 38 The diagram shows a configuration that may include an upper end portion 121a and a lower end portion 121b disposed below the upper end portion 121a. The upper end portion 121a and the lower end portion 121b may be integrally formed.

[0625] The coil portion 1230 may be at least one layer wound on the ferrite core 1230.

[0626] The coil portion 1230 is electrically connected to the substrate 2100. The coil portion 1230 may include a first connecting portion 1231 and a second connecting portion 1232 for connection to the substrate 2100. The first connecting portion 1231 is disposed on the fixing bracket 1600, and its end is electrically connected to a first terminal portion 2131 of the substrate 2100. The second connecting portion 1232 is disposed on the fixing bracket 1600, and its end is electrically connected to a second terminal portion 2132 of the substrate 2100. The fixing bracket 1600 may have slots for the first connecting portion 1231 and the second connecting portion 1232, respectively. These slots may be formed on the outside of the fixing bracket 1600 along the length of the stylus 1000. Having the first connecting portion 1231 and the second connecting portion 1232 of the coil portion 1230 through these slots provides the advantage of protecting the first connecting portion 1231 and the second connecting portion 1232 from external impacts.

[0627] Figure 69 It is only Figure 58 The diagram shows a 3D view of the 1600 fixed bracket. Figure 70 Observing from other directions Figure 69 The diagram shows a 3D view of the 1600 fixed bracket. Figure 71 Observing from other directions Figure 68 Part of a 3D diagram.

[0628] Reference Figures 68 to 71 The mounting bracket 1600 is fixedly disposed inside the housing 1010. The mounting bracket 1600 can be disposed inside the housing 1010 between the inductor section 1200 and the substrate support 1900. One end of the mounting bracket 1600 is coupled to the inductor section 1200, and the other end of the mounting bracket 1600 can be coupled to the substrate support 1900.

[0629] One end of the mounting bracket 1600 may include an insertion slot 1620 into which the other end of the ferrite core 1210 of the inductor section 1200 is inserted. The insertion slot 1620 may be defined by the first partition 1611 and the inner sidewall 1622 of the mounting bracket 1600.

[0630] The first partition 1611 can contact the other end of the ferrite core 1210, and the first partition 1611 has a through hole 1610 through which the core 1020 passes.

[0631] The inner wall 1622 may include a plurality of protrusions 1621 protruding into the insertion groove 1620. The plurality of protrusions 1621 contact the outside of the other end of the ferrite core 1210 and can serve to hold the position of the ferrite core 1210.

[0632] The other end of the fixing bracket 1600 may include mounting holes 1660 and 1665 into which the mounting portions 1960 and 1965 of the substrate bracket 1900 are inserted. At least one mounting hole 1660 or 1665 may be provided, as shown in the figure, with one on the upper side and one on the lower side of the fixing bracket 1600. The mounting portion 1960 of the substrate bracket 1900 is engaged with the mounting groove 1660, therefore the fixing bracket 1600 can be engaged with the substrate bracket 1900.

[0633] The other end of the mounting bracket 1600 may include a guide protrusion 1667. The guide protrusion 1667 may extend along the length direction of the mounting bracket 1600. The guide protrusion 1667 may engage with the guide portion 1967 of the substrate bracket 1900. Since the guide protrusion 1667 engages with the guide portion 1967 of the substrate bracket 1900, the mounting bracket 1660 can be configured along the length direction of the stylus 1000.

[0634] The other end of the fixing bracket 1600 may include a second partition 1680. The second partition 1680, together with the substrate bracket 1900, fixes the position of the elastic member 1800. That is, the elastic member 1800 can be fixedly installed between the second partition 1680 and the substrate bracket 1900.

[0635] The fixed bracket 1600 is configured to surround the movable bracket 1300, the elastic body 1700, and the elastic component 1800. The fixed bracket 1600 may have an internal accommodating space 1640 for the movable bracket 1300, the elastic body 1700, and the elastic component 1800. Within the accommodating space 1640 of the fixed bracket 1600, the movable bracket 1300 can perform linear reciprocating motion.

[0636] The mounting bracket 1600 may include two or more electrode patterns 1690. At least two electrode patterns 1690 may be disposed on the outer surface of the mounting bracket 1600. For example, the electrode patterns 1690 may be disposed on the outer surfaces of both sides of the mounting bracket 1600. The electrode patterns 1690 may be plated onto the outer surface of the mounting bracket 1600, which is made of a non-conductive material. For example, the electrode patterns 1690 may be formed on the outer surface of the non-conductive mounting bracket 1600 by laser direct structuring (LDS) and laser manufacturing antenna (LMA).

[0637] The outer surface of the mounting bracket 1600 may have a groove (or cavity) corresponding to the shape of the electrode pattern 1690. The electrode pattern 1690 may be plated inside the groove (or cavity). Although not shown separately, as another embodiment, a protrusion corresponding to the shape of the electrode pattern 1690 may be formed on the outer surface of the mounting bracket 1600, and the electrode pattern 1690 may also be plated on the protrusion.

[0638] The electrode pattern 1690 can be configured around the guide groove 1630 of the fixing bracket 1600, and can have a concave or convex shape. The electrode pattern 1690 is shaped like a '. One end of the electrode pattern 1690 can be in contact with or spaced apart from the electrode pattern 1390 of the movable bracket 1300 by a predetermined interval, and the other end of the electrode pattern 1690 can be electrically connected to the terminal portions 2191 and 2192 of the substrate 2100.

[0639] As the movable support 1300 moves in sync with the movement of the core 1020, the electrode pattern 1690 can either come into contact with the electrode pattern 1390 of the movable support 1300 or be positioned at a predetermined interval away from the electrode pattern 1390 of the movable support 1300. This will be explained further with reference to other figures.

[0640] Figure 72 It was removed Figure 68 The figure shows a perspective view of the inductor section 1200 and the mounting bracket 1600. Figure 73 Observing from other directions Figure 72 3D image, Figure 74 yes Figure 72 Cross-sectional view.

[0641] Reference Figures 67 to 72 The movable support 1300 moves synchronously with the core 1020. When one end of the core 1020 is subjected to an external force, the core 1020 moves inward toward the outer shell 1010, and the movable support 1300 moves together with the core 1020.

[0642] The movable support 1300 is configured to accommodate the other end of the core 1020, the magnet 1400, and the protective component 1500. The movable support 1300 may have a receiving portion for accommodating the other end of the core 1020, the magnet 1400, and the protective component 1500. Here, the movable support 1300 may also be referred to as a movable portion.

[0643] Inside the receiving portion, the magnet 1400 and the protective member 1500 are configured to surround the other end of the core 1020. For this purpose, the magnet 1400 is cylindrical and may have a through portion extending through the other end of the core 1020 inside, and the protective member 1500 is cylindrical and may have a through portion extending through the other end of the core 1020 inside.

[0644] The magnet 1400 comprises a magnetic material and moves synchronously with the core 1020. The movement of the magnet 1400 changes the distance between it and the inductor section 1200, which is fixedly disposed inside the housing 1010. This change in distance alters the inductance of the inductor section 1200.

[0645] The protective component 1500 comprises a resilient material and can be configured to be fitted between the other end of the core 1020 and the movable support 1300. The other end of the core 1020 can be protected by the protective component 1500, and since the protective component 1500 is fitted between the other end of the core 1020 and the movable support 1300, the movable support 1300 can move synchronously with the core 1020.

[0646] like Figure 71As shown, the protective member 1500 may include a protrusion 1510 protruding from the outside to the outside. The protrusion 1510 can be inserted into an insertion groove 1310 formed in the movable bracket 1300. Through the protrusion 1510 of the protective member 1500 and the insertion groove 1310 of the movable bracket 1300, the protective member 1500 can be stably fixed to the movable bracket 1300, so that the other end of the core 1020 can be fixed to the movable bracket 1300.

[0647] The movable support 1300 may include a first protrusion 1330a and a second protrusion 1330b. The first protrusion 1330a and the second protrusion 1330b may protrude outwards from the outer surface of the movable support 1300 or in a direction perpendicular to the length direction of the stylus 1000. The first protrusion 1330a and the second protrusion 1330b may be configured on... Figure 68 The fixed bracket 1600 shown in the figure has a guide hole 1630. When the movable bracket 1300 moves synchronously with the core 1020, the first protrusion 1330a and the second protrusion 1330b can move along the guide hole 1630 of the fixed bracket 1600.

[0648] The movable support 1300 may include a third protrusion 1350. The third protrusion 1350 may protrude outwards from the outer surface of the movable support 1300 or in a direction perpendicular to the length direction of the stylus 1000. The third protrusion 1350 may be configured to... Figure 68 The guide hole 1650 of the fixed bracket 1600 is shown in the figure. When the movable bracket 1300 moves synchronously with the movement of the core 1020, the third protrusion 1350 can move along the guide hole 1650 of the fixed bracket 1600.

[0649] The movable support 1300 may include an extension 1370. The extension 1370 may extend from the outside of the movable support 1300 along the length of the stylus 1000. Alternatively, the extension 1370 may extend from the outside of the movable support 1300 along the length of the core 1020. The extension 1370 may have a structure and shape that allows it to be configured within the elastomer 1700. An extension 1870 of the elastic member 1800 may be configured at the end of the extension 1370.

[0650] The movable support 1300 may include an electrode pattern 1390. The electrode pattern 1390 may be disposed on the outside of the movable support 1300, on the outside of which an extension 1370 is formed and on a first protrusion 1330a and a second protrusion 1330b.

[0651] Electrode pattern 1390 can be electrically connected via contact with the elastomer 1700 of the extension 1370 surrounding the movable support 1300. Electrode pattern 1390 can be electrically connected via contact with... Figure 68 The electrode pattern 1690 of the fixed bracket 1600 shown in the figure is electrically connected, and the contact between the core 1020 and the electrode pattern 1690 of the fixed bracket 1600 can be released by the movement of the core 1020 to achieve electrical separation.

[0652] The electrode pattern 1390 may be plated on the outside of the non-conductive material movable bracket 1300. For example, the electrode pattern 1390 may be formed on the outside of the non-conductive material movable bracket 1300 by laser direct structuring (LDS) and laser manufacturing antenna (LMA).

[0653] The electrode pattern 1390 may include a basic electrode pattern 1391 and a first extended pattern 1393a and a second extended pattern 1393b.

[0654] The basic electrode pattern 1391 is disposed on the outside of the movable support 1300 and can be configured to surround the extension 1370 of the movable support 1300. The basic electrode pattern 1391 is in contact with one end of the elastomer 1700.

[0655] The first extended pattern 1393a and the second extended pattern 1393b extend from both sides of the first electrode pattern 1391, respectively. The first extended pattern 1393a is disposed on the first protrusion 1330a, and the second extended pattern 1393b can be disposed on the second protrusion 1330b. The first extended pattern 1393a and the second extended pattern 1393b can be coupled with... Figure 68 The electrode pattern 1690 of the fixed bracket 1600 shown in the figure is in contact, or the contact is released by the movement of the core 1020.

[0656] The elastomer 1700 is made of a conductive material and may have a spring shape. The elastomer 1700 can be disposed between the movable support 1300 and the elastic component 1800. Specifically, the elastomer 1700 can be assembled between the movable support 1300 and the elastic component 1800 in a partially compressed state. When the external force applied to the movable support 1300, which moves synchronously with the core 1020, is less than the outward pushing force of the partially compressed elastomer 1700, the elastomer 1700 is not compressed; when the external force is greater than the elastic force, the elastomer 1700 begins to compress.

[0657] The extension 1370 of the movable support 1300 and the extension 1870 of the elastic member 1800 can be disposed together inside the elastomer 1700. This allows the internal space of the elastomer 1700 to be utilized, thus having the advantage of reducing the internal volume of the stylus 1000.

[0658] One end of the elastomer 1700 is electrically connected to the electrode pattern 1390 of the movable support 1300, and the other end is electrically connected to the terminal portion 2110 of the substrate 2100. The elastomer 1700 may include a connecting line 1710 connecting the elastomer 1700 and the terminal portion 2110 of the substrate 2100. The connecting line 1710 may be connected at one end to the elastomer 1700 and at the other end to the terminal portion 2110 of the substrate 2100. To protect and guide the connecting line 1710, the elastic member 1800 and the substrate support 1900 may have guide grooves for configuring the connecting line 1710.

[0659] The elastic component 1800 is made of a non-conductive material and has a predetermined elasticity. For example, the elastic component 1800 can be rubber.

[0660] The elastic member 1800 can be configured between the movable support 1300 and the substrate support 1900.

[0661] Figure 75 It is only Figure 72 The diagram shows a perspective view of the elastic component 1800. Figure 76 yes Figure 72 The figure shows a perspective view of the substrate support 1900 and the substrate 2100.

[0662] Reference Figures 69 to 76 The elastic member 1800 may include an extension 1870. The extension 1870 may extend from the outer side of the elastic member 1800 toward the movable support 1300. The extension 1870 may be disposed inside the elastic body 1700.

[0663] The elastic member 1800 may include a guide groove 1810. The guide groove 1810 may be formed on the outside of the elastic member 1800 along the length direction of the stylus 1000. The connecting line 1710 of the elastomer 1700 may be disposed in the guide groove 1810.

[0664] The elastic member 1800 may include a mounting groove 1850. The mounting groove 1850 is formed on the outside of the elastic member 1800. The mounting groove 1850 may be disposed on the side opposite to the extension 1870. The mounting portion 1910 of the substrate support 1900 can be inserted into the mounting groove 1850. The mounting groove 1850 may have a hook groove 1851 with a shape corresponding to the protrusion 1915 of the mounting portion 1910 of the substrate support 1900. The elastic member 1800 can thus be stably fixedly mounted to the substrate support 1900.

[0665] The substrate support 1900 supports the substrate 2100 inside the housing 1010 and is combined with the elastic member 1800 to support the elastic member 1800.

[0666] The substrate support 1900 may include a side portion 1940 that guides and supports the side portion of the substrate 2100.

[0667] The substrate support 1900 may include a mounting portion 1910 for engaging with the elastic member 1800. The mounting portion 1910 protrudes from the substrate support 1900 toward the movable support 1300. The mounting portion 1910 may include protrusions 1915 protruding from the outside. The protrusions 1915 may protrude in a direction perpendicular to the protrusion direction of the mounting portion 1910.

[0668] The substrate support 1900 may include a guide groove 1920. The guide groove 1920 may guide and protect the connecting wires 1710 of the elastomer 1700.

[0669] The substrate 2100 is disposed on the substrate support 1900.

[0670] The substrate 2100 may include a plurality of terminal portions 2110, 2131, 2132, 2191, and 2192. Among the plurality of terminal portions 2110, 2131, and 2132, terminal portion 2110 is electrically connected to the elastomer 1700, and the first terminal portion 2131 and the second terminal portion 2132 are electrically connected to the coil portion 1230 of the inductor portion 1200. The third terminal portion 2191 and the fourth terminal portion 2192 are electrically connected to electrode patterns 1690 respectively disposed on both sides of the outer side of the fixing bracket 1600.

[0671] The substrate 2100 includes a capacitor section (not shown). The capacitor section (not shown) of the substrate 2100 is configured to form one or more capacitors.

[0672] The substrate 2100 may include one or more capacitors electrically connected to the capacitor section (not shown) and circuit patterns of multiple terminal sections 2110, 2131, 2132.

[0673] Figure 77 It is used to explain with Figures 68 to 76 The diagram illustrates the movement of the movable support 1300 caused by the movement of the core 1020, and the electrical contact and release between the fixed support 1600 and the movable support 1300.

[0674] Figure 77 (A) shows the core 1020 without any external force being applied. Figure 77 (B) shows the core 1020 being subjected to a predetermined external force, causing the movable support 1300 to move in one direction.

[0675] First, refer to Figure 77In (A), without any external force applied to the core 1020, the electrode pattern 1390 of the movable bracket 1300 contacts the electrode pattern 1690 of the fixed bracket 1600. That is, the electrode pattern 1390 of the movable bracket 1300 and the electrode pattern 1690 of the fixed bracket 1600 are electrically connected to each other.

[0676] The elastomer 1700 pushes the second protrusion 1330b of the moving bracket 1300 toward the core 1020 side, so that the electrode pattern 1390 disposed outside the second protrusion 1330b can maintain contact with the electrode pattern 1690 of the fixed bracket 1600.

[0677] Then, refer to Figure 77 (B) When a predetermined external force is applied to the core 1020, and the core 1020 moves in one direction, the movable bracket 1300 moves in conjunction with the core 1020 in that direction. Due to the movement of the movable bracket 1300 in that direction, the second protrusion 1330b also moves in that direction. Due to the movement of the second protrusion 1330b, the electrode pattern 1390 of the movable bracket 1300 is released from contact with the electrode pattern 1690 of the fixed bracket 1600. Similarly, the first protrusion 1330a located on the opposite side of the second protrusion 1330b also moves, and the electrode pattern 1390 of the movable bracket 1300 is released from contact with the electrode pattern 1690 of the fixed bracket 1600. Furthermore, the elastomer 1700 is compressed by the movement of the movable bracket 1300.

[0678] like Figure 77 As shown in Figure (B), when the core 1020 is moved in one direction by a predetermined external force, the contact between the electrode pattern 1390 of the moving bracket 1300 and the electrode pattern 1690 of the fixed bracket 1600 is released. Due to this release of contact, the capacitance of the capacitor portion (not shown) mounted on the substrate 2100 changes. This change in capacitance alters the frequency of the pen signal emitted from the stylus 1000. The receiving side receiving the pen signal senses the changed frequency to determine if the stylus 1000 has contacted the screen.

[0679] As the movable support 1300 moves, the magnet 1400 disposed inside the movable support 1300 also moves. As the magnet 1400 moves, the distance between the inductor section 1200 and the magnet 1400 increases. Due to the change in the distance between the inductor section 1200 and the magnet 1400, the inductance of the inductor section (not shown) changes. This change in inductance occurs simultaneously with the change in capacitance described above. It is possible that the change in capacitance changes more dominantly than the change in inductance. It is easier to drastically change capacitance than to drastically change inductance within the limited space inside the stylus casing. On the other hand, depending on the situation, it is also possible that the change in inductance changes more dominantly than the change in capacitance. Alternatively, it is possible that the changes in capacitance and inductance are nearly identical. Regardless of which of the three cases is true, the movement of the movable support 1300 causes both capacitance and inductance to change, resulting in a change in the resonant frequency of the resonant circuit formed by the inductor section 1200 and the capacitor section. The receiving side of the pen signal can determine that the stylus 1000 has contacted the screen by sensing this change in resonant frequency.

[0680] Figure 78 The diagram shows Figure 77 Each of (A) and (B), Figure 79 The stylus, according to other embodiments of the present invention, is simplified. Figure 77 Each of (A) and (B) constitutes an equivalent circuit diagram.

[0681] Reference Figure 78 and Figure 79 In (A) and (B), a plurality of capacitors C1, C2, C3, and Cs are disposed on substrate 2100. The plurality of capacitors C1, C2, C3, and Cs can constitute a capacitor section (not shown). At least one of the plurality of capacitors C1, C2, C3, and Cs is connected in parallel to maintain a certain capacitance value. Figure 77 The contact or de-contact between the electrode pattern 1690 of the fixed bracket 1600 and the electrode pattern 1390 of the movable bracket 1300 shown in the figure, and the auxiliary capacitor Cs being connected in parallel with the basic capacitor or not connected to the basic capacitor.

[0682] First, such as Figure 78 (A) and Figure 79As shown in Figure (A), when the core 1020 is not subjected to any external force, the auxiliary capacitor Cs is connected in parallel with the basic capacitors C1, C2, and C3 because the electrode pattern 1690 of the fixed bracket 1600 and the electrode pattern 1390 of the movable bracket 1300 are in contact with each other. Therefore, the capacitance of the capacitor section (not shown) is the sum of the capacitance values ​​of the basic capacitors C1, C2, and C3 and the capacitance of the auxiliary capacitor Cs.

[0683] After that, as Figure 78 (B) and Figure 79 As shown in Figure (B), when a predetermined external force is applied to the core 1020, the electrode pattern 1390 of the moving bracket 1300 is released from contact with the electrode pattern 1690 of the fixed bracket 1600 by the movement of the moving bracket 1300 synchronized with the movement of the core 1020. Therefore, the auxiliary capacitor Cs cannot be electrically connected to the basic capacitors C1, C2, and C3, and the capacitance of the capacitor section (not shown) changes to the capacitance value of the basic capacitors C1, C2, and C3.

[0684] In particular, refer to Figure 79 (b) It can be confirmed that the electrode pattern 1390 of the movable bracket 1300 and the electrode pattern 1690 of the fixed bracket 1600 are in contact at two points. Regarding this, as... Figure 72 and Figure 73 The illustration can be understood from the fact that the fixed bracket 1600 has two electrode patterns 1690, and the movable bracket 1300 has a first extended pattern 1393a and a second extended pattern 1393b disposed on the first protrusion 1330a and the second protrusion 1330b.

[0685] If the external force applied to the core 1020 does not reach the extent that it completely separates the first extension pattern 1393a and the second extension pattern 1393b from the two electrode patterns 1690 of the fixed bracket 1600, that is, if the first extension pattern 1393a is separated from one electrode pattern 1690 of the fixed bracket 1600, but the second extension pattern 1393b is not separated from the other electrode pattern 1690 of the fixed bracket 1600, the auxiliary capacitor Cs remains connected in parallel with the basic capacitors C1, C2, and C3.

[0686] Conversely, as long as the external force applied to the core 1020 is sufficient to completely separate both the first extension pattern 1393a and the second extension pattern 1393b from the two electrode patterns 1690 of the fixing bracket 1600, the auxiliary capacitor Cs disconnects from the electrical connection of the basic capacitors C1, C2, and C3. Therefore, when using the stylus 1000 according to another embodiment of the present invention, since a reference pressure for distinguishing between hover and contact is clearly provided, it has the advantage of a clear distinction between hover and contact. In particular, even if manufacturing engineering problems during stylus production or user negligence cause either of the first extension pattern 1393a or the second extension pattern 1393b to fail to contact either of the two electrode patterns 1690 of the fixing bracket 1600, the other extension pattern and the other electrode pattern in the stylus 1000 according to another embodiment of the present invention can still maintain contact, thus having the advantage of being able to clearly distinguish between hover and contact states.

[0687] Figure 80 Viewed from the 1020 side of the core Figure 66 The illustration shows a perspective view of a stylus 1000 according to another embodiment of the present invention. Figure 81 (A) is cut by A-A' Figure 80 The illustration shows a partial cross-sectional view of the Stylus 1000. Figure 81 (B) is cut by B-B' Figure 80 The illustration shows a partial cross-sectional view of the Stylus 1000. Figure 82 It is shown Figures 80 to 81 The illustration shows the side view A, B and cross-sectional view of the ferrite core 1210.

[0688] Reference Figure 68 , Figures 80 to 82 The outer shell 1010 of the stylus 1000 has a rectangular cylindrical shape with rounded corners, and the portion of the outer shell 1010 that exposes a part of the core 1020 has a shape in which its width becomes narrower as it approaches the outer side.

[0689] Based on the shape of the housing 1010, the internal components also correspond to the shape of the housing 1010. The ferrite core 1210 of the inductor section 1200 in the internal configuration also has an optimized structure corresponding to the shape of the housing 1010.

[0690] like Figure 81 The illustrations (A) and (B) show the first vertical direction in the ferrite core 1210 that is perpendicular to the axial direction (x, or the length direction of the stylus 1000). Figure 80The shape of the first cross-section cut in the A-A' direction is different from that cut in the second vertical direction ( Figure 80 The second cross-sectional shape is obtained by cutting along the B-B' direction. Specifically, the thickness w1 of the ferrite core 120 in the first vertical direction is different from the thickness w2 in the second direction. More specifically, the thickness w1 in the first vertical direction is less than the thickness w2 in the second direction. The thickness w1 in the first vertical direction can be defined as the shortest distance from the through hole 1210h of the ferrite core 1210 to the outside of the ferrite core 1210 in the first cross-sectional shape, and the thickness w2 in the second vertical direction can be defined as the shortest distance from the through hole 1210h of the ferrite core 1210 to the outside of the ferrite core 1210 in the second cross-sectional shape. Alternatively, unlike the figures shown, the thickness w1 in the first vertical direction can be the total thickness of the ferrite core 1210 in the first cross-sectional shape, and the thickness w2 in the second vertical direction can be the total thickness of the ferrite core 1210 in the second cross-sectional shape.

[0691] The ferrite core 1210 has a cylindrical or cylindrical shape. A planar portion 1210d may be disposed on at least a portion of the outer surface of the ferrite core 1210. Other portions of the outer surface of the ferrite core 1210 may also be disposed with planar portions corresponding to the planar portion 1210d. Through the planar portion 1210d, the ferrite core 1210 can be stably disposed inside the housing 1010. The planar portion 1210d is formed to extend from one end of the ferrite core 1210 to the other end along the axial direction x of the ferrite core 1210.

[0692] One end of the ferrite core 1210 may include at least two or more curved portions 1210c. Regarding at least a portion of the curved portions 1210c, such as... Figure 81 The figures (A) and (B) show that the curved surface 1210c may appear in the second cross-sectional shape but not in the first cross-sectional shape. The curved surface 1210c may be a surface that curves from one side of one end of the ferrite core 1210 toward the portion adjacent to the through-hole 1210h of the ferrite core 1210. This curved surface 1210c may be disposed on opposite sides of one end of the ferrite core 1210 with reference to the through-hole 1210h.

[0693] Curved face 1210c Figure 82 As shown in diagrams ①②③, the closer to the axial direction x of the ferrite core 1210, the more it changes from an aspherical shape to a spherical shape. Figure 82 ③ shows that the curved surface 1210c is an aspherical shape. Figure 82 ① shows that the curved surface 1210c is spherical. Furthermore, Figure 82② shows that the curved surface 1210c is an intermediate shape between an aspherical shape and a spherical shape.

[0694] At one end of the ferrite core 1210, the planar portion 1210d has a shape in which its width becomes narrower as it gets closer to the axial direction x of the ferrite core 1210. The width of the planar portion 1210d can decrease non-linearly.

[0695] When using the ferrite core 1210 described above, as above Figures 39 to 41 The inductor section 1200, including the ferrite core 1210, can be configured closer to the tip of the core 1020 within the stylus 1000. Therefore, since the inductor section 1200 can be positioned relatively closer to the receiver side (not shown), it has the advantage of increasing the magnitude of the pen signal received from the receiver side.

[0696] on the other hand, Figures 80 to 82 The ferrite core 1210 shown in the diagram can be applied to... Figure 36 or Figure 55 The illustrated stylus. Furthermore, Figure 36 or Figure 55 The ferrite core of the stylus shown in the illustration can also be used in... Figure 66 The stylus.

[0697] Figure 83 It is used for explanation Figure 82 The diagram shows a modified example of the ferrite core 1210. Figure 84 yes Figure 83 The illustration shows a perspective view of the inductor section 1200' of the ferrite core 1210' with the coil 1230' wound around it.

[0698] Reference Figure 83 The ferrite core 1210' has a cylindrical shape.

[0699] One end of the ferrite core 1210' may include a curved surface 1210c'. The curved surface 1210c' may be a curved surface that bends from one end of the ferrite core 1210' to the portion adjacent to the through hole 1210h of the ferrite core 1210' towards the through hole 1210h side.

[0700] The ferrite core 1210' has a through hole 1210h extending along the axial direction x. The through hole 1210h has a certain diameter from one end to the other.

[0701] like Figure 83 As shown in diagrams ①②③, the closer the curved surface 1210c' is to the axial direction x of the ferrite core 1210', the smaller its outer diameter becomes, while its inner diameter remains constant. The inner diameter is defined as the through-hole 1210h. Alternatively, as... Figure 83As shown in diagrams ①②③, the closer the curved surface 1210c' is to the axial direction x of the ferrite core 1210', the smaller the thickness between the outer and inner diameters becomes.

[0702] The rate of decrease in the outer diameter along the axial direction x of the ferrite core 1210' or the rate of decrease in the thickness (between the outer diameter and the inner diameter) can be non-linear. More specifically, when one end of the ferrite core 1210' is divided into an upper end (the part containing ③), a middle end (the part containing ②), and a lower end (the part containing ①), the rate of decrease in the outer diameter or the thickness from the upper end to the middle end can be relatively greater than the rate of decrease from the middle end to the lower end. In other words, there can be a relatively rapid rate of decrease from the upper end to the middle end, and a relatively slow rate of decrease from the middle end to the lower end.

[0703] Reference Figure 84 The coil 1230' can be wound around the outside (or outer circumference) of the ferrite core 1210'.

[0704] This inductor section 1200', which includes a ferrite core 1210' and a coil 1230', can be configured in a cylindrical housing (not shown) instead of Figure 80 The illustration shows the interior of the housing 1000. Although not shown separately, the ferrite core of the inductor section may have a shape corresponding to the internal shape of the housing.

[0709] The sealing components 200a, 200a', and 200b of a stylus 100 according to one embodiment of the present invention and the sealing components 2000a, 2000a', and 2000b of a stylus 1000 according to another embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0710] Water inflow path

[0711] Figure 85 This shows that moisture flows in through the core opening of the outer shell. Figure 42 The diagram shows the first and second water inflow paths of the stylus. Figure 86 This shows that moisture flows in through the core opening of the outer shell. Figure 34 The diagram shows the first and second water inflow paths of the stylus.

[0712] like Figure 85 As shown, moisture can flow in through the core opening (not shown) of the outer casing 101. Figure 42 The interior of the stylus 100 is shown. Here, the core opening (not shown) may refer to the space between the outer casing 101 and the core 102.

[0713] Specifically, such as Figure 85 As shown in (a), moisture can flow into the interior of the stylus 100 through a first moisture inflow path P1. The first moisture inflow path P1 is the path through which moisture flows into the interior of the stylus 100 through the core opening (not shown) of the housing 101 and through the space between the housing 101 and the inductor section 120. Alternatively, specifically, as... Figure 85 As shown in (b), moisture can flow into the interior of the stylus 100 through the second moisture inflow path P2. The second moisture inflow path P2 is the path through which moisture flows into the interior of the stylus 100 through the core opening of the outer shell 101 (not shown) and through the through hole of the ferrite core 121.

[0714] like Figure 86As shown, moisture can flow in through the core opening (not shown) of the outer shell 1010. Figure 34 The interior of the stylus 1000 shown. Specifically, as... Figure 86 As shown in (a), moisture can flow into the interior of the stylus 1000 through a first moisture inflow path P1'. The first moisture inflow path P1' is the path through which moisture flows into the interior of the stylus 1000 through the core opening (not shown) of the housing 1010 and through the space between the housing 1010 and the inductor section 1200. Alternatively, specifically, as... Figure 86 As shown in (b), moisture can flow into the interior of the stylus 1000 through the second moisture inflow path P2', which is the path through which moisture flows into the interior of the stylus 1000 through the core opening of the outer shell 1010 (not shown) and through the through hole of the ferrite core 1210.

Specifically, the multiple water inflow paths P1, P2 may include a first water inflow path P1 and a second water inflow path P2. Furthermore, specifically, the multiple sealing components 200a, 200a', 200b may include a first sealing component 200a, 200a' capable of blocking the first water inflow path P1 and a second sealing component 200b capable of blocking the second water inflow path P2.

[0729] On the other hand, as mentioned above, such as Figure 85 The stylus 100 shown may also include an inner housing 110 disposed inside the housing 101. When the stylus 100 also includes the inner housing 110, the first sealing member 200a' may be configured to be in close contact with the inner wall of the inner housing 110.

Furthermore, the second sealing member 2000b can be configured to be in close contact with the core 1020 at the portion of the core 1020 passing through the through hole 1610 of the partition 1611. Therefore, the second sealing member 2000b can prevent moisture from flowing into the second moisture inflow path P2'. On the other hand, the details regarding the fixing bracket 1600, the partition 1611, and the through hole 1610 are as described above.

[0738] The stylus includes a first sealing component and a second sealing component.

[0739] Figure 93 It is shown Figure 85 and Figure 86 The diagram shows that each of the styluses also has a first sealing component and a second sealing component attached.

[0740] like Figure 93 As shown in (a), Figure 85The stylus 100 shown may include multiple sealing components 200a, 200a', and 200b capable of blocking multiple water inflow paths P1 and P2 through the core opening (not shown) of the housing 101. Specifically, the multiple water inflow paths P1 and P2 may include a first water inflow path P1 and a second water inflow path P2. Specifically, the multiple sealing components 200a, 200a', and 200b may include a first sealing component 200a and 200a' capable of blocking the first water inflow path P1 and a second sealing component 200b capable of blocking the second water inflow path P2. That is, the stylus 100 can block the first water inflow path P1 and the second water inflow path P2 through the first sealing components 200a and 200a' and the second sealing component 200b.

[0741] like Figure 93 As shown in (b), Figure 86 The stylus 1000 shown may include multiple sealing components 2000a, 2000a', 2000b capable of blocking multiple water inflow paths P1', P2' through the core opening (not shown) of the housing 1010. Specifically, the multiple water inflow paths P1', P2' may include a first water inflow path P1' and a second water inflow path P2'. Furthermore, specifically, the multiple sealing components 2000a, 2000a', 2000b may include a first sealing component 2000a, 2000a' capable of blocking the first water inflow path P1' and a second sealing component 2000b capable of blocking the second water inflow path P2'.

[0742] Stylus pen including a sealing component with a tight-fitting part

[0743] Figure 94 It is shown Figure 91 and Figure 92 A schematic diagram of a modified example of the sealing component shown.

[0744] As mentioned above, Figure 91 The second sealing member 200b shown can be disposed on the partition 132 to fill the outer contour of the through hole 132h of the partition 132 through which the core 102 passes the first fixing member 130. Furthermore, the second sealing member 200b can be configured to be in close contact with the core 102 at the portion of the core 102 passing through the through hole 132h of the partition 132. Therefore, the second sealing member 200b can prevent moisture from flowing into the second moisture inflow path P2. On the other hand, the details regarding the first fixing member 130, the partition 132, and the through hole 132h are as described above.

[0745] In addition, as mentioned above, such as Figure 92 As shown, the second sealing member 2000b can be configured in the partition 1611 to fill the outer contour of the through hole 1610 of the partition 1611 through which the core 1020 passes through the fixing bracket 1600. Furthermore, the second sealing member 2000b can be configured to be in close contact with the core 1020 at the portion of the core 1020 passing through the through hole 1610 of the partition 1611. Therefore, the second sealing member 2000b can prevent moisture from flowing into the second moisture inflow path P2'. On the other hand, the details regarding the fixing bracket 1600, the partition 1611, and the through hole 1610 are as described above.

[0746] On the other hand, such as Figure 94 As shown in (a), Figure 85 The second sealing member 200b of the stylus 100 shown may include a sealing member body 203 and a sealing portion 201. Specifically, the sealing member body 203 may be disposed on the partition 132 to fill the outline of the through hole 132h of the partition 132. Furthermore, the sealing portion 201 may be cylindrical in shape having a height in the longitudinal direction of the core 102, and the second sealing member 200b may be configured to be in close contact with the core 102 within the sealing portion 201. Therefore, when the core 102 moves in the longitudinal direction of the core 102, at least a portion of the sealing portion 201 can remain in close contact with the core 102. That is, when the core 102 moves in the longitudinal direction of the core 102, the second sealing member 200b can block water flowing in through the second water inflow path P2 from passing through the through hole 132h located on the partition 132 of the first fixing member 130 through the sealing portion 201.

[0747] In addition, such as Figure 94 As shown in (b), Figure 86 The second sealing member 2000b of the stylus 1000 shown may include a sealing member body 2003 and a sealing portion 2001. Specifically, the sealing member body 2003 may be disposed on the partition 1611 to fill the outline of the through hole 1610 of the partition 1611. Furthermore, the sealing portion 2001 may be cylindrical in shape, having a height in the longitudinal direction of the core 1020, and the second sealing member 2000b may be configured to be in close contact with the core 1020 within the sealing portion 2001. Therefore, when the core 1020 moves in the longitudinal direction of the core 1020, at least a portion of the sealing portion 2001 can remain in close contact with the core 1020. That is, when the core 1020 moves in the length direction of the core 1020, the second sealing member 2000b can block the water flowing in through the second water inflow path P2' through the through hole 1610 on the partition 1611 of the fixed bracket 1600 by the tight part 2001.

[0748] Stylus including cushioning components

[0749] See Figure 42 , Figure 87 and Figure 89 ,like Figure 85 The stylus 100 shown may include a housing 101, a core 102, an inductor section 120, a capacitor section (not shown), a first fixing member 130, a buffer member 115, and first sealing members 200a and 200a'. Details of the housing 101, core 102, inductor section 120, capacitor section (not shown), first fixing member 130, and first sealing members 200a and 200a' are described above.

[0750] Specifically, such as Figure 85 The stylus 100 shown may further include a buffer member 115 that can be disposed between the inner surface of the housing 101 and the other end of the ferrite core 121. Here, the buffer member 115 may be configured to surround at least a portion of the other end of the ferrite core 121. Additionally, the buffer member 115 may be configured to be in close contact with the housing 101 and the other end of the ferrite core 121. Therefore, the buffer member 115 can block the path of moisture flowing into the interior of the stylus 1000 through the core opening (not shown) of the housing 101.

[0751] On the other hand, such as Figures 37 to 40 As shown, the other end of the ferrite core 121 may have a tapered shape with a diameter or width that gradually decreases towards the end. Additionally, the other end of the ferrite core 121 may include at least one curved portion 121c that bends inward from the outside. The buffer member 115, by including the curved portion 121c at the other end of the ferrite core 121, can have a smaller thickness compared to a case where the other end of the ferrite core 121 does not include the curved portion 121c.

[0752] See Figure 67 , Figure 88 and Figure 90 The stylus 1000 may include a housing 1010, a core 1020, an inductor section 1200, a capacitor section (not shown), a mounting bracket 1600, a buffer member 1150, and first sealing members 2000a and 2000a'. Details of the housing 1010, core 1020, inductor section 1200, capacitor section (not shown), mounting bracket 1600, and first sealing members 2000a and 2000a' are as described above.

[0753] Specifically, such as Figure 86The stylus 1000 shown may include a buffer member 1150 that can be disposed between the inner surface of the housing 1010 and the other end of the ferrite core 1210. Here, the buffer member 1150 may be configured to surround at least a portion of the other end of the ferrite core 1210. Additionally, the buffer member 1150 may be configured to be in close contact with the housing 1010 and the other end of the ferrite core 1210. Therefore, the buffer member 1150 can block the path of moisture flowing into the interior of the stylus 1000 through the core opening (not shown) of the housing 1010.

[0754] On the other hand, such as Figures 37 to 40 As shown, the other end of the ferrite core 1210 may have a tapered shape with a diameter or width that gradually decreases towards the end. Additionally, the other end of the ferrite core 1210 may include at least one curved portion 121c that bends inward from the outside. By including the curved portion 121c at the other end of the ferrite core 121, the buffer member 115 can have a smaller thickness compared to the case where the other end of the ferrite core 121 does not include the curved portion 121c.

Specifically, Figure 95 Image (a) is a partial perspective view of the stylus including the third sealing component. Furthermore, Figure 95 (b) is Figure 95 (a) A portion of the cross-sectional view cut along C-C'.

[0757] like Figure 95 As shown, the stylus 1000 may include a core opening (not shown) capable of blocking passage through the housing 1010. Figure 86 The third sealing component 2000c of the first water inflow path P1' shown.

[0758] like Figure 95 As shown in (a), the third sealing member 2000c can be configured to surround at least a portion of the outer surface of the ferrite core 1210. Specifically, the third sealing member 2000c can surround at least a portion of the outer surface of the ferrite core 1210 near the core opening (not shown). Furthermore, the third sealing member 2000c can be configured to contact the coil portion 1230, but is not limited thereto.

[0759] like Figure 95As shown in (b), the third sealing member 2000c can be configured to fit tightly against the inner wall of the housing 1010. Therefore, the third sealing member 2000c can prevent moisture from flowing in. Figure 86 The first water inflow path P1' is shown.

[0760] Buffer component and fourth sealing component

[0761] Figure 96 It shows the blockage Figure 86 This is a schematic diagram of one embodiment of the buffer components for the first and second water inflow paths in the stylus shown. Specifically, Figure 96 (a) is a portion of a perspective view of the stylus including the cushioning component. Furthermore, Figure 96 (b) is Figure 96 (a) A portion of the cross-section cut along D-D'.

[0762] like Figure 96 As shown, the stylus 1000 may include a buffer member 1150. Specifically, the buffer member 1150 may be configured to surround at least a portion of the exterior of both the core 1020 and the ferrite core 1210 near the core opening (not shown). More specifically, the buffer member 1150 may be formed with a predetermined hole (not shown). The buffer member 1150 may accommodate the core 1020 and the ferrite core 1210 through the predetermined hole (not shown).

[0763] like Figure 96 As shown in (a), the buffer member 1150 may include a fourth sealing member 2000d. Specifically, the fourth sealing member 2000d may be formed in a ring shape, but is not limited thereto. The fourth sealing member 2000d may be attached to one end of the core opening (not shown) side of the buffer member 1150.

[0764] More specifically, the fourth sealing component 2000d can be used to block, for example... Figure 86 The first water inflow path P1' is shown. Figure 96 As shown in (b), the outer contour 2000d-1 of the fourth sealing member 2000d can be configured to fit tightly against the inner wall of the housing 1010. Therefore, the fourth sealing member 2000d can prevent moisture from flowing into the first moisture inflow path P1'.

[0765] On the other hand, the fourth sealing component 2000d can be used to block, such as Figure 86 The second water inflow path P2' is shown. Figure 96As shown in (b), the inner contour 2000d'-2 of the fourth sealing member 2000d can be configured to be in close contact with the core 1020 and / or the ferrite core 1210. Therefore, the fourth sealing member 2000d can prevent moisture from flowing into the second moisture inflow path P2'. However, the invention is not limited thereto; the invention may include a fourth sealing member 2000d whose inner contour 2000d'-2 is spaced apart from the core 1020 and / or the ferrite core 1210 by a predetermined interval.

[0766] According to one embodiment of the present invention, the fourth sealing member 2000d can be combined with one end of the buffer member 1150 as a separate component. Alternatively, the fourth sealing member 2000d can also be combined with one end of the buffer member 1150 to form an integral part with the buffer member 1150. However, it is not limited to this.

[0767] According to one embodiment of the invention, a fourth sealing member 2000d can be formed at one end of the buffer member 1150 by a predetermined process. For example, the fourth sealing member 2000d can be formed by at least one process selected from the group consisting of tape-applying and coating processes. However, it is not limited thereto.

[0768] Third sealing component, buffer component and fourth sealing component

[0769] Figure 97 It shows including Figure 95 The sealing components shown and Figure 96 A schematic diagram of the stylus with a buffer component is shown.

[0770] like Figure 97 As shown, the stylus 1000 may include a third sealing member 2000c and a buffer member 1150. The buffer member 1150 may include a fourth sealing member 2000d. Specifically, the fourth sealing member 2000d and the buffer member 1150 may be configured to surround at least a portion of the exterior of the core 1020 or the ferrite core 1210 near the core opening (not shown) in a mutually contacting state. Therefore, the third sealing member 2000c and the fourth sealing member 2000d, in association with each other, prevent moisture from flowing into the first moisture inflow path P1' and the second moisture inflow path P2'.

[0771] Third water inflow path

[0772] Figure 98 This indicates that water flows in through the button. Figure 34 The diagram shows the third water inflow path of the stylus. Specifically, Figure 98 (a) shows a 3D view of the stylus and the third water inflow path. Additionally, Figure 98 (b) will be Figure 98 A portion of the perspective view with the outer shell removed (a) and the third water inflow path are shown together.

[0773] like Figure 98 As shown, Figure 34 The stylus 1000 shown may include a button holder 1190. Specifically, the button holder 1190 is configured to engage with a substrate holder 1900 within a housing 1010 to cover at least a portion of the substrate 2100. Additionally, the button holder 1190 has a predetermined groove (not shown) for engaging with a button portion 1090, thereby accommodating the button portion 1090.

[0774] like Figure 98 As shown in (a), water can flow in through the third water inflow path P3'. Figure 34 The interior of the stylus 1000 shown. Specifically, as... Figure 98 As shown in (b), the third moisture inflow path P3' may include path P3'-1, which passes through the gap between the button portion 1090 and the housing 1010 and reaches the substrate 2100 through a hole (Hole, not shown) formed on the button holder 1190. Alternatively, the third moisture inflow path P3' may include path P3'-2, which passes through the gap between the button portion 1090 and the housing 1010 and reaches the substrate 2100 along the outside of the button holder 1190.

[0775] Fourth water inflow path

Specifically, Figure 99 (a) shows a 3D view of the stylus and the fourth water inflow path. Additionally, Figure 99 (b) will be Figure 99 A portion of the perspective view of (a) with the outer shell removed, along with the fourth water inflow path, is shown together.

[0777] like Figure 99 As shown, Figure 34 The stylus 1000 shown may include a clicker housing 2300, a click cover 2400, a click button 2500, and a click spring member 2510.

[0778] Specifically, the snap button 2500 is configured to insert from the opposite side of the pen tip into a hole (Hole, not shown) formed at the end of the snap housing 2300. The snap button 2500 can be used to perform specific operations of the stylus 1000. The snap button 2500 can be pressed by external force towards the core opening (not shown).

[0779] Specifically, one end of the snap-fit ​​elastic member 2510 can be connected to the snap-fit ​​button 2500. The other end of the snap-fit ​​elastic member 2510 can be connected to the snap-fit ​​housing 2300. When the snap-fit ​​button 2500 is pressed towards the core opening (not shown), the snap-fit ​​elastic member 2510 is compressed, storing elastic potential energy. When the force pressing the snap-fit ​​button 2500 disappears, the snap-fit ​​button 2500 moves in the opposite direction to the core opening (not shown) using the elastic potential energy stored in the snap-fit ​​elastic member 2510.

[0780] Specifically, the snap cover 2400 and snap housing 2500 are configured to surround the snap button 2500 and the snap elastic member 2510 inside the housing 1010. The snap housing 2300 may have a hole (Hole, not shown) for receiving the snap button 2500. Furthermore, the snap housing 2300 can be coupled to the snap cover 2400. The snap cover 2400 is connected to the snap housing 2300 via a predetermined fastening part (not shown) and can be coupled to an end of the substrate support 1900. On the other hand, as described above, the snap cover 2400 may have a predetermined groove (not shown) formed near the portion where it engages with the substrate support 1900.

[0781] like Figure 99 As shown in (a), water can flow in through the fourth water inflow path P4'. Figure 34 The interior of the stylus 1000 shown. Specifically, as... Figure 99 As shown in (b), the fourth moisture inflow path P4' is the path that passes through the joint between the housing 1010 and the snap-fit ​​housing 2300, and along the outside of the snap-fit ​​housing 2300 and the snap-fit ​​cover 2400 to the substrate 2100.

[0782] Packaged components

[0783] Figure 100 It shows the blockage Figure 98 A schematic diagram of the encapsulation component for the third water inflow path in the stylus shown.

[0784] like Figure 100 As shown, Figure 34 The stylus 1000 shown may include an encapsulation component 1290. Specifically, the encapsulation component 1290 can be coupled to the button holder 1190 via a predetermined slot (not shown) formed in the button holder 1190. Additionally, the encapsulation component 1290 is used to block... Figure 98 The third water inflow path P3' is shown and can block the hole (Hole, not shown) formed in the button holder 1190. The encapsulation pad component 1290 can be configured to be in close contact with the button holder 1190.

[0785] like Figure 100 As shown, the encapsulation component 1290 may have a protrusion 1291 formed on its edge. Specifically, the protrusion 1291 may be formed to fit tightly against the inner wall of the housing 1010.

[0786] Therefore, the encapsulation component 1290 can prevent moisture from flowing into the substrate 2100 through the gap between the button portion 1090 and the housing 1010 and along the hole (not shown) formed on the button holder 1190 or the outside of the button holder 1190.

Additionally, Figure 101 (b) is Figure 101 (a) A portion of the cross-section cut along E-E'.

[0789] like Figure 101 As shown in (a), Figure 34 The stylus 1000 shown may include features for blocking Figure 99 The fifth sealing member 2000e is shown in the fourth moisture inflow path P4'. Specifically, the fifth sealing member 2000e can be disposed in a groove (not shown) formed in the snap cover 2400 near the junction of the snap cover 2400 and the substrate support 1900. The fifth sealing member 2000e can surround the outside of the snap cover 2400 in the groove (not shown) formed in the snap cover 2400.

[0790] like Figure 101 As shown in (b), the fifth sealing component 2000e can be configured to... Figure 34 The inner wall of the outer casing 1010 shown is tightly fitted. Therefore, the fifth sealing component 2000e can prevent moisture from flowing into the fourth moisture inflow path P4'.

[0793] like Figure 102 As shown, Figure 34The stylus 1000 shown may have multiple waterproof mechanisms. Specifically, the waterproof mechanisms are used to block the path of water flowing into the interior of the stylus 1000.

[0794] For example, the path of water inflow can be selected from at least one path chosen from the group consisting of the first water inflow path P1', the second water inflow path P2', the third water inflow path P3', and the fourth water inflow path P4. However, it is not limited to this.

[0795] For example, the waterproofing mechanism may be any one of the components selected from the group consisting of the first sealing component 2000a, 2000a', the second sealing component 2000b, the third sealing component 2000c, the buffer component 1150 including the fourth sealing component 2000d, the fifth sealing component 2000e, and the encapsulation component 1290. However, it is not limited to this.

[0796] like Figure 102 As shown, Figure 34 The stylus 1000 shown may include a first sealing component 2000a', a third sealing component 2000c, a buffer component 1150 including a fourth sealing component 2000d, an encapsulation component 1290, and a fifth sealing component 2000e. Thus, the stylus 1000 can prevent moisture from flowing into its interior through the first moisture inflow path P1', the second moisture inflow path P2', the third moisture inflow path P3', and the fourth moisture inflow path P4'.

[0797] See above. Figure 90 As described above, the first sealing member 2000a' can be configured to surround at least a portion of the outer surface of the fixing bracket 1600. Additionally, the first sealing member 2000a' can be configured to fit tightly against the inner wall of the housing 1010. Therefore, the first sealing member 2000a' can prevent moisture from flowing into the first moisture inflow path P1'.

[0798] See above. Figure 95 As described above, the third sealing member 2000c can be configured to surround at least a portion of the outer surface of the ferrite core 1210. Specifically, the third sealing member 2000c can surround at least a portion of the outer surface of the ferrite core 1210 near the core opening (not shown). Furthermore, the third sealing member 2000c can be configured to contact the coil portion 1230, but is not limited thereto.

[0799] Furthermore, the third sealing component 2000c can be configured to fit tightly against the inner wall of the housing 1010. Therefore, the third sealing component 2000c can prevent moisture from flowing into the first moisture inflow path P1'.

[0800] See Figure 96As described above, the stylus 1000 may include a buffer member 1150. Specifically, the buffer member 1150 may be configured to surround at least a portion of the exterior of the core 1020 and the ferrite core 1210 near the core opening (not shown).

[0801] Additionally, the buffer member 1150 may include a fourth sealing member 2000d. Specifically, the fourth sealing member 2000d may be formed in the shape of a ring, but is not limited thereto. The fourth sealing member 2000d may be attached to one end of the core opening (not shown) side of the buffer member 1150.

[0802] More specifically, the fourth sealing component 2000d can be used to block the first moisture inflow path P1'. For example... Figure 96 As shown in (b), the outer contour 2000d-1 of the fourth sealing member 2000d can be configured to fit tightly against the inner wall of the housing 1010. Therefore, the fourth sealing member 2000d can prevent moisture from flowing into the first moisture inflow path P1'.

[0803] Additionally, the fourth sealing component 2000d can be used to block the second moisture inflow path P2'. For example... Figure 96 As shown in (b), the inner contour 2000d'-2 of the fourth sealing member 2000d can be configured to be in close contact with the core 1020 and / or the ferrite core 1210. Therefore, the fourth sealing member 2000d can prevent moisture from flowing into the second moisture inflow path P2'.

[0804] According to one embodiment of the present invention, the fourth sealing member 2000d may be incorporated as a separate component into one end of the buffer member 1150. Alternatively, the fourth sealing member 2000d may also be incorporated into one end of the buffer member 1150 to form an integral part thereof. However, it is not limited thereto.

[0805] According to one embodiment of the invention, a fourth sealing member 2000d can be formed at one end of the buffer member 1150 by a predetermined process. For example, the fourth sealing member 2000d can be formed by at least one process selected from the group consisting of tape application and coating processes. However, it is not limited to this.

[0806] See Figure 100 As mentioned above, Figure 34The stylus 1000 shown may include an encapsulation component 1290. Specifically, the encapsulation component 1290 can be coupled to the button holder 1190 via a predetermined groove (not shown) formed on the button holder 1190. Additionally, the encapsulation component 1290 serves to block the third moisture inflow path P3' and can block a hole (Hole, not shown) formed on the button holder 1190. The encapsulation pad component 1290 can be configured to be in close contact with the button holder 1190.

[0807] Additionally, the encapsulation component 1290 may have a protrusion 1291 formed on its edge. Specifically, the protrusion 1291 may be formed to fit tightly against the inner wall of the housing 1010.

[0808] Therefore, the encapsulation component 1290 can prevent moisture from flowing into the substrate 2100 through the gap between the button portion 1090 and the housing 1010 and along the hole (Hole, not shown) formed on the button holder 1190 or the outside of the button holder 1190.

[0809] See above. Figure 101 The above, Figure 34 The stylus 1000 shown may include a fifth sealing member 2000e for blocking the fourth moisture inflow path P4'. Specifically, the fifth sealing member 2000e may be disposed in a groove (not shown) formed in the snap cover 2400 near the point where the snap cover 2400 engages with the substrate support 1900. The fifth sealing member 2000e may surround the outside of the snap cover 2400 within the groove (not shown) formed in the snap cover 2400.

[0810] Additionally, the fifth sealing component 2000e can be configured to fit tightly against the inner wall of the housing 1010. Therefore, the fifth sealing component 2000e can prevent moisture from flowing into the fourth moisture inflow path P4'.
