Description

The present invention relates to a touch processing device for a transmitter, and more particularly to a touch processing device for a transmitter that actively transmits pressure related sensing information.

The touch panel or touch screen is a modern and important human-machine interface. In addition to detecting proximity or contact (collectively referred to as proximity), the touch panel is also used to detect a close pen or touch. The tip of the pen is used to facilitate the user to precisely control the trajectory of the tip touch.

The pen can use the pen tip to actively emit an electrical signal, which is referred to herein as an active stylus. When the tip of the pen is in contact with the control panel, the electrode on the touch panel is affected by the electrical signal and has an electromagnetic response, and the corresponding electromagnetic response of the electrical signal can be detected to detect that the pen is closely connected to the sensing. Electrode, and know the relative position of the pen tip and the touch panel.

The conventional active stylus includes a wired active stylus and a wireless active stylus. The wired active stylus can obtain power from the touch panel directly from the connection line connected to the touch panel, or can transmit signals to the touch panel by the connection line, for example, transmitting a signal indicating the pressure received by the pen tip. The biggest disadvantage of the wired active stylus is that the obstruction of the connecting line causes inconvenience in use. However, the wireless active stylus must solve the synchronization problem between the wired active stylus and the controller that detects the active stylus. This does not exist between the wired active stylus and the controller. problem.

In addition, one difference between an active stylus and a passive stylus is the active touch. The control pen can be added to the pressure sensing, and the pressure receiving device in the active stylus can convey the degree of the force of the pen tip, and the controller or the host that detects the active stylus can obtain the information of the force of the tip of the active stylus. However, how to provide the information of the pen tip force to the controller for detecting the active stylus is another problem that must be solved in the technical field. For example, it may be through wireless communication, but it will increase the cost and power consumption of wireless communication. The controller or host that detects the active stylus must also have the capability of such wireless communication to increase system complexity. In addition, the information on the force of the pen tip may be expressed by the analog signal size, but may be misjudged due to changes in temperature or humidity, the distance between the pen and the touch panel, and interference of noise.

Accordingly, there is a need for a master who can actively send an electrical signal to the pressure it receives. Move the stylus.

The invention will be described in detail below with some embodiments. However, the scope of the present invention is not limited by the embodiments, except as to the disclosed embodiments, which are subject to the scope of the claims. In order to provide a clearer description and to enable those skilled in the art to understand the present invention, the various parts of the drawings are not drawn according to their relative sizes, and the ratio of certain dimensions or other related scales may be highlighted. It is exaggerated to come out, and the irrelevant details are not completely drawn, in order to simplify the illustration.

Please refer to the first figure, which is a schematic diagram of a touch system 100 according to an embodiment of the invention. The touch system 100 includes at least one transmitter 110, a touch panel 120, a touch processing device 130, and a host 140. In this embodiment, the active stylus capable of actively transmitting an electrical signal is taken as an example, and the actual implementation is not limited thereto. The touch system 100 can include a plurality of transmitters 110. The touch panel 120 is formed on a substrate, and the touch panel 120 can be a touch screen. The invention does not limit the form of the touch panel 120.

In one embodiment, the touch panel 120 includes a plurality of first electrodes 121 and a plurality of second electrodes 122, and a plurality of capacitive coupling sensing points are formed at the overlapping portions. The first electrode 121 and the second electrode 122 are respectively connected to the touch processing device 130. In the mutual capacitance detection mode, the first electrode 121 may be referred to as a first conductive strip or a driving electrode, and the second electrode 122 may be referred to as a second conductive strip or a sensing electrode. The touch processing device 130 can use the driving voltage (the voltage of the driving signal) to the first electrodes 121, and measure the signal changes of the second electrodes 122 to know that there is an external conductive object approaching or contacting (referred to as a proximity). The touch panel 120. One of ordinary skill in the art can understand that the touch processing device 130 can utilize mutual power. Capacitance or self-capacitance to detect proximity events and proximity objects is not described in detail here. In addition to the mutual capacitance or self-capacitance detection method, the touch processing device 130 can also detect the electrical signal emitted by the transmitter 110, thereby detecting the relative relationship between the transmitter 110 and the touch panel 120. position. In one embodiment, the signal changes of the first electrode 121 and the second electrode 122 are respectively measured to detect the signal of the transmitter 110, thereby detecting the relative position of the starter 110 and the touch panel 120. Since the signal of the transmitter 110 is different from the frequency of the mutual capacitance or the self-capacitance driving signal, and is not mutually resonant, the touch processing device 130 can separately distinguish the signal and the mutual capacitance emitted by the signal generator 110 or Self-capacitance signal. In another embodiment, the touch panel 120 can be a surface capacitive touch panel having one electrode at four corners or four sides, and the touch processing device 130 measures the signal changes of the four electrodes separately or simultaneously. The relative position of the starter 110 and the touch panel 120 is detected.

Also included in the first figure is a host 140, which may be a central processing unit, or It is the main processor in the embedded system, or other forms of computer. In an embodiment, the touch system 100 can be a tablet computer, and the host computer 140 can be a central processing unit that executes a tablet operating program. For example, the tablet executes an Android operating system, which is an ARM (ARM) processor that executes an Android operating system. The present invention does not limit the form of information transmitted between the host 140 and the touch processing device 130, as long as the transmitted information is related to the proximity event occurring on the touch panel 120.

Because the transmitter needs to actively send an electrical signal, the transmitter 110 or the active stylus needs The power required to supply electrical signals. In an embodiment, the source of electrical energy of the transmitter 110 can be a battery, particularly a rechargeable battery. In another embodiment, the source of electrical energy of the pen may be a capacitor, in particular a super capacitor (Ultra-capacitor or Super-capacitor), such as electricity. Double capacitors (EDLC, Electrical Double Layered Capacitor), virtual capacitors (Pseudocapacitor), and hybrid capacitors. The charging time of the supercapacitor is on the order of seconds, while in the embodiment of the invention, the discharge time of the supercapacitor is on the order of an hour. In other words, the active pen can be used for a long time only by charging for a short time.

In an embodiment, the touch panel 120 periodically emits a lighthouse signal. (beacon signal). After the transmitter 110 or the stylus tip is connected to the touch panel 120, the transmitter 110 can sense the beacon signal by using the pen tip, and then start to send an electrical signal for a period of time for the touch panel 120 to detect. use. In this way, the transmitter 110 may stop emitting the electrical signal when the beacon signal is not detected, by extending the power usage time of the transmitter 110.

The above beacon signal can utilize a plurality of first electrodes 121 and/or second electrodes 122 to issue. In an embodiment, when the first electrode 121 is used to generate the driving signal of the mutual capacitance touch detection, the driving signal and the beacon signal have different frequencies, and are not the resonance waves of the other side. Therefore, the beacon signal can be simultaneously emitted during the issuance of the driving signal, that is, mutual capacitance touch detection and electrical signal detection are simultaneously performed. In another embodiment, the driving signal and the beacon signal may be sent in turn, that is, the mutual capacitance touch detection and the electrical signal detection are performed in a time division manner, and the driving signal and the beacon signal may have the same frequency or different frequencies.

In an embodiment, in order to make the transmitter 110 at a distance from the touch panel 120 The beacon signal can be detected, and the touch processing device 130 can send a driving signal to all the first electrodes 121 and the second electrodes 122 on the touch panel 120 at the same time, so that the signal strength of the touch panel 120 is generated. The sum is the largest.

Please refer to the second figure, which is a transmitter according to an embodiment of the invention. Schematic diagram of the interior of 110. The transmitter 110 includes a first signal source 211, a second signal source 212, a first component 221 having a first impedance Z1, a second component 222 having a second impedance Z2, and a sharp segment 230. The first signal sent by the first signal source 211 is transmitted to the touch panel 120 via the first component 221 and the pen tip segment 230. Similarly, the second signal sent by the second signal source 212 is transmitted to the touch panel 120 via the second component 222 and the pen tip segment 230.

In an embodiment, the first signal is a signal including a first frequency f1, The second signal is a signal comprising a second frequency f2. The first frequency f1 and the second frequency f2 may be a square wave signal, a sine wave signal, or a pulse width modulation (Pulse Width Modulation) signal. In an embodiment, the first frequency f1 is different from the frequency of the beacon signal and the frequency of the driving signal, and is different from the resonant frequency of the frequency of the beacon signal and the frequency of the driving signal. The second frequency f2 is different from the first frequency f1, the frequency of the beacon signal and the frequency of the driving signal, and is different from the first frequency f1, the resonant frequency of the signal of the beacon frequency signal and the driving frequency.

The signals of the two frequencies each pass through the first element 221 having the first impedance Z1 The second element 222 having the second impedance Z2 is then mixed and fed into the tip section 230. The first element 221 and the second element 222 described above may be impedances caused by a resistive element, an inductive element, a capacitive element (such as a solid capacitor), or any combination thereof. In the embodiment shown in the second figure, the second impedance Z2 may be fixed, the first impedance Z1 being variable, and corresponding to the amount of change of a certain sensor.

In another embodiment, the first impedance Z1 and the second impedance Z2 are both variable, The ratio of the two of them corresponds to the amount of change of a certain sensor. In an embodiment, the sensor may be a retractable elastic nib, and the first impedance Z1 may correspond to the stroke of the elastic nib or The degree of force changes. In some examples, the first impedance Z1 described above linearly corresponds to a change in a physical quantity of the sensor. However, in another example, the first impedance Z1 described above nonlinearly corresponds to a change in the physical quantity of the sensor.

The first element 221 and the second element 222 described above may be different electronic elements Pieces. For example, the first component 221 is a resistor and the second component 222 is a capacitor, and vice versa. For another example, the first component 221 is a resistor and the second component 222 is an inductor, and vice versa. For another example, the first component 221 is an inductor and the second component 222 is a capacitor, and vice versa. At least one of the first impedance Z1 and the second impedance Z2 is variable, such as a resistance variable resistor, a capacitance variable capacitor, or an inductor having a variable inductance value. When one of the first impedance Z1 and the second impedance Z2 is immutable, it can be set by using existing electronic components, such as a general fixed resistance resistor element, a fixed capacitance capacitor element or a fixed inductance value. Inductive component.

In an embodiment, the first component 221 can be a force sensing resistor (FSR, force The sensing resistor has a resistance value corresponding to the applied force to produce a predictable change, and the second component 222 can be a fixed resistor. In another embodiment, the first component 221 can be a variable resistor. Therefore, among other conditions, the ratio of the intensity M1 of the signal portion of the first frequency f1 to the intensity M2 of the signal portion of the second frequency f2 among the electrical signals emitted by the pen tip 230 will be the first impedance Z1. It is inversely proportional to the ratio of the second impedance Z2. In other words, M1/M2=k(Z2/Z1).

Therefore, when the transmitter 110 is suspended above the touch panel 120, the pen tip segment 230 There is no displacement or force. Therefore, among the electrical signals detected by the touch panel 120, the ratio of the intensity M1 of the signal portion of the first frequency f1 to the intensity M2 of the signal portion of the second frequency f2 is a fixed value or default value. Or in another embodiment, (M1-M2)/(M1+M2) or (M2-M1)/(M1+M2) The ratio is also a fixed value or a preset value. In addition to this, the pressure value can also be expressed by the ratio of M1/(M1+M2) or M2/(M1+M2). In addition to the four ratios described above, one of ordinary skill in the art will also be able to replace any ratio that involves strengths M1 and M2. In other words, when the ratio is detected as the fixed value, it can be determined that the sensor does not sense any change in the physical quantity. In an embodiment, the transmitter 110 does not touch the touch panel 120.

After the sender 110 contacts the touch panel 120, the pen tip segment 230 is affected by Force and displacement stroke. The first impedance Z1 of the first element 221 is changed corresponding to the stroke or the degree of force of the pen tip segment 230, so that the intensity of the signal portion of the signal portion of the first frequency f1 and the signal portion of the second frequency f2 among the electrical signals The ratio of M2 changes, unlike the fixed value or the preset value described above. The touch panel 120 can use the above relationship to generate a corresponding sensing value according to the ratio. The aforementioned fixed value or preset value is not limited to a single value, and may be a range within an error tolerance.

It should be noted that the ratio does not necessarily have a linear relationship with the sensed value. more Further, the sensing value does not necessarily have a linear relationship with the displacement stroke of the sensor or the degree of force of the sensor. The sensed value is only a value sensed by the touch panel 120, and the present invention is not limited to the relationship. For example, the touch panel 120 can use the lookup table or a plurality of calculation formulas to correspond to the sensed value from the ratio.

Please refer to the third figure, which is a transmitter according to an embodiment of the present invention. Schematic diagram of the interior of 110. Similar to the embodiment of the second figure, the transmitter 110 includes a first signal source 211, a second signal source 212, a first capacitor 321 having a first capacitance value C1, and a second capacitor value C2. A second capacitor 322, and a tip segment 230.

The two signal sources 211 and 212 may be pulse width modulation first signal sources, respectively (PWM1) and pulse width modulation second signal source (PWM2). The frequencies of the two sources can be the same or different. The transmitter 110 includes a second capacitor 322 having a fixed capacitance value C2 and a first capacitor 321 having a variable capacitance value C1, which are respectively connected to the signal sources PWM2 212 and PWM1 211 described above. Since the capacitance value C1 changes with the pressure value received by the pen tip segment 230, the embodiment shown in the third figure may include a capacitive force sensor or a force sensing capacitor (FSC, Force Sensing Capacitor). In an embodiment, the capacitive force sensor can be implemented using a printed circuit board (PCB) or other material. The structure of the force sensing capacitor will be described later in this application.

The ratio of the intensities of the two sources, and the ratio of the impedances of the two capacitors 321 and 322 Inverse ratio. When the tip segment 230 of the stylus does not touch the object, or the force sensor does not detect the force, the impedance value of the first capacitor 321 does not change. The impedance ratio of the two capacitors 321 and 322 is also fixed. When the transmitter 110 is suspended above the touch panel/screen 120 and the transmitted electrical signal can be detected, the intensity ratio of the two sources is fixed.

But when the nib segment 230 of the transmitter 110 contacts an object, or a force sensor When the force is detected, the impedance of the first capacitor 321 changes accordingly. The impedance ratio of the two capacitors 321 and 322 also changes. When the transmitter 110 touches the surface of the touch panel/screen 120 and the electrical signal emitted by the transmitter 110 can be detected, the intensity ratio of the two signal sources varies with the force received by the force sensor. .

Please refer to FIG. 4A, which is a transmitter according to an embodiment of the present invention. Schematic diagram of the interior of 110. Similar to the embodiment of the third figure, the transmitter 110 includes a first signal source 211, a second signal source 212, a first capacitor 321 having a first capacitance value C1, and a second power. The second capacitor 322 of the capacitance C2, and the nib segment 230. The transmitter 110 can include a plurality of sensors for detecting a plurality of states. In one embodiment, the nib segment 230 includes a pressure sensor for detecting the state of the tip of the stylus and is reflected above the electrical signal it emits. In another embodiment, the transmitter 110 can include a plurality of buttons, such as an Eraser button and a Barrel button. In other embodiments, the transmitter 110 can also include a switch for sensing whether the pen tip is in contact with a touch screen or other object. One of ordinary skill in the art will appreciate that the transmitter 110 can include more buttons or other forms of sensors and is not limited to the examples described above.

In the embodiment of FIG. A, the first capacitor 321 is connected in parallel with two other rubbers. The wiper capacitor 441 and the pen holder capacitor 442 are respectively connected to the above-mentioned Eraser button and the Barrel button, that is, the switches SWE and SWB. When the above button or switch is pressed, the capacitors 441 and 442 are connected in parallel with the first capacitor 321 so that the capacitance value in the PWM1 signal path changes, resulting in a change in the impedance ratio of the PWM1 and PWM2 signal paths, so that the two signals The intensity ratio changes accordingly.

Since the capacitance value C1 of the first capacitor 321 and the impedance value will change, when After the wiper capacitor 441 is connected in parallel with the sheath capacitor 442, the ratio of the parallel impedance value to the impedance value of the second capacitor 322 falls within a range. In the embodiment shown in FIG. A, it is assumed that within the variable range of the first capacitor 321, the signal strength ratio of PWM1/PWM2 falls within a first range. After the first capacitor 321 is connected in parallel with the sheath capacitor 442, that is, after the pen button is pressed, the signal ratio of PWM1/PWM2 falls within a second range. After the first capacitor 321 is connected in parallel with the eraser capacitor 441, that is, after the eraser button is pressed, the signal ratio of PWM1/PWM2 falls within a third range. After the first capacitor 321 is connected in parallel with the sheath capacitor 442 and the eraser capacitor 441, that is, the pen After the lever button and the eraser button are simultaneously pressed, the signal ratio of PWM1/PWM2 falls within a fourth range. The capacitance values and impedance values of the pen holder capacitor 442 and the eraser capacitor 441 can be adjusted such that the first range, the second range, the third range, and/or the fourth range do not overlap.

Please refer to the sixth figure, which is a touch device according to an embodiment of the invention. A schematic flow diagram of a method for detecting a value of a hairpin or an active stylus tip. The method can be performed by the touch processing device 130 of the first embodiment.

The touch processing device 130 can determine the relative position of the transmitter 110 and the touch panel 120 according to the signal strength received by the plurality of first electrodes 121 and the plurality of second electrodes 122. In addition to this, the method shown in the sixth figure can be used to determine the force sensing value of the transmitter 110. In one embodiment, the force sensing value is the pressure value experienced by the nib segment 230.

The embodiment of the sixth figure may correspond to the embodiments of the second to fifth figures. The first two steps 610 and 620 respectively calculate the signal strengths M1 and M2 corresponding to the first signal source 211 and the second signal source 212. . These two steps 610 and 620 can be performed in either order or simultaneously. When the electrical signal emitted by the first signal source 211 has a first frequency f1 and a second signal source 212 When the electrical signal has a second frequency f2, the signal strength M1 corresponds to the intensity of the signal of the first frequency f1, and the signal strength M2 corresponds to the strength of the signal of the second frequency f2.

In addition to the five ratios described above, one of ordinary skill in the art will also be able to replace any ratio that involves the strengths M1 and M2. Then, step 640 is executed to determine whether it is a preset value or falls within a preset range according to the proportional value. If the determination result is true, step 650 is executed to determine that the sender 110 is floating and does not touch the touch panel 120. Otherwise, step 660 is performed to calculate the sensed value of the nib segment 230 based on the scale value. The sensed value may or may not be related to the degree of force and/or the stroke, or may be related to the degree of force and/or stroke. The step of calculating the sensing value can be calculated by using the look-up table method, the linear interpolation method, and the quadratic curve method, and the correspondence between the proportional value and the sensed value is determined.

When the embodiment of the sixth figure is applied to the embodiments of the fourth A diagram and the fourth B diagram, Additional steps may be performed at step 660. For example, when applied to the embodiment of FIG. 4A, it can be determined that the scale value calculated in step 630 falls within the first range, the second range, the third range, or the fourth range described above. Accordingly, in addition to the sensed value of the nib segment 230, it can be inferred whether the pen button and/or the eraser button are pressed. Similarly, when used in the embodiment of FIG. 4B, it can be determined that the scale value calculated in step 630 is in the first range described above. Within the circumference, the fifth range, the sixth range, or the seventh range. Accordingly, in addition to the sensed value of the nib segment 230, it can be inferred whether the pen button and/or the eraser button are pressed.

In contrast, when the electrical signal is received via the touch panel 120, the first frequency f1 of the demodulated electrical signal or the intensity M1 of the signal portion of the first frequency group F1 and the second frequency f2 and the second frequency group are used. The ratio of the intensity M2 of the signal portion of the group F2 can determine the extent to which the nib segment 230 is stressed.

Please refer to FIG. 7C, which is a transmitter according to an embodiment of the present invention. Schematic diagram of the interior of 110. The difference from the embodiment of FIG. 7B is that the transmitter 110 no longer includes the single signal source 714 described above, but directly uses the electrical signal obtained by the transmitter wired communication unit 771 as a signal source. Since the transmitter wired communication unit 771 is connected to the host wired communication unit 781, the above electrical signals can use the power of the host 140.

Please refer to FIG. 7D, which is a transmitter according to an embodiment of the present invention. Schematic diagram of the interior of 110. The difference from the embodiment of the seventh embodiment is that the transmitter 110 no longer includes the single signal source 714 described above, but directly from the touch panel 120 when the pen tip segment 230 is directly connected to the touch panel 120. The signal obtained by the first electrode 121 and/or the second electrode 122 is used as a signal source.

It is worth mentioning that the embodiments of Figures 7 to D can be implemented by applying the third figure.

Please refer to FIG. 8 , which is a touch device according to an embodiment of the invention. A schematic flow chart of the method for detecting the tip of the hairpin. The eighth embodiment is a method of detecting a sensed value similar to the sixth embodiment. The sixth figure is used to calculate the signal strengths M1 and M2 corresponding to the first frequency (group) and the second frequency (group), and then use the ratio values of the two to calculate the sensing value. The embodiment of the eighth embodiment is applicable to an embodiment in which only a single signal source is fed, and the first current amount I1 and the second current amount I2 corresponding to the first element 221 and the second element 222 are calculated, and the two are used. The scale value is used to calculate the sensed value.

The method may be due to the control unit 760 of the seventh A to D diagram embodiment. carried out. The first two steps 810 and 820 respectively calculate the first current amount I1 and the second current amount I2 corresponding to the first element 221 and the second element 222. These two steps 810 and 820 can be performed in either order or simultaneously. Then, in step 830, a proportional value is calculated based on I1 and I2. This ratio has been given several examples, such as I1/(I1+I2), I2/(I1+I2), I1/I2, I2/I1, (I1-I2)/(I1+I2). , or (I2-I1) / (I1 + I2), and the like. Then, step 840 is executed to determine whether it is a preset value or falls within a preset range according to the scale value. If the determination result is true, step 850 is performed, and the sender 110 is considered to be floating and does not touch the touch panel 120. Otherwise, step 860 is performed, according to the The scale value calculates the sensed value of the nib segment 230. The sensed value may or may not be related to the degree of force and/or the stroke, or may be related to the degree of force and/or stroke. The step of calculating the sensing value can be calculated by using the look-up table method, the linear interpolation method, and the quadratic curve method, and the correspondence between the proportional value and the sensed value is determined.

In some embodiments, when the first element 221 or the second element 222 is open to the other When the corresponding elements are connected in parallel, as in the embodiments of FIGS. 4A and 4B, additional steps may be performed at step 860. For example, when applied to the embodiment of FIG. 4A, it can be determined that the scale value calculated in step 830 falls within the first range, the second range, the third range, or the fourth range described above. Accordingly, in addition to the sensed value of the nib segment 230, it can be inferred whether the pen button and/or the eraser button are pressed. Similarly, when used in the embodiment of FIG. 4B, it can be determined that the scale value calculated in step 830 falls within the first range, the fifth range, the sixth range, or the seventh range described above. Accordingly, in addition to the sensed value of the nib segment 230, it can be inferred whether the pen button and/or the eraser button are pressed.

Please refer to FIG. 9A, which is a transmitter according to an embodiment of the present invention. A timing diagram of the signal modulation of 110. The embodiment of the ninth A diagram can be applied to the transmitters 110 of the second to fifth figures. The horizontal axis of the ninth A diagram is the time axis, and the order is from left to right. As shown, an optional noise detection period may be included before the touch panel/screen 120 emits a beacon signal. The noise detected during this noise detection may come from the touch panel/screen and the electronic system or background environment in which it is located. The touch panel/screen 120 and the touch processing device 130 can detect one or more frequencies included in the noise signal. The section on noise detection will be explained later.

In an embodiment, the touch panel/screen 120 emits a beacon signal, the transmitter 110 includes a demodulation transformer that can detect the beacon signal. Please refer to FIG. 29, which is a block diagram of a detection lighthouse signal system according to an embodiment of the invention. The detection lighthouse letter The system 2900 includes a receiving electrode 2910, a detecting module 2920, and a demodulator 2930. In one embodiment, the receiving electrode 2910 may be the ring electrode 550 described above, or the pen tip segment 230 described above, or other electrodes. The receiving electrode 2910 sends the received signal to the subsequent detecting module 2910.

The detection module 2920 includes an analog front end 2921 and a comparator 2922. ability Those of ordinary skill in the art can understand what the analog front end does and will not be detailed here. In this embodiment, the analog front end 2921 can include a voltage value that represents the strength of the signal. The comparator 2922 is for comparing a reference voltage Vref with a voltage signal indicating the strength of the received signal. When the voltage signal is higher than the reference voltage, it indicates that a strong enough signal is received, so the comparator 2922 outputs an activation signal or an enable signal to the demodulation converter 2930. The demodulation transformer 2930 can perform demodulation on the received signal to know whether the frequency of the beacon signal is included in the received signal. When the voltage signal is lower than the reference voltage, the comparator 2922 can output a shutdown signal to the demodulator 2930, and the demodulator 2930 stops demodulating the received signal.

When the transmitter 110 does not receive the beacon signal for a period of time, it can switch to In a sleep mode, the demodulator 2930 described above is turned off to save power consumption. However, since the detection module 2920 consumes less power, it is possible to continuously detect whether the received signal strength exceeds a predetermined value in the sleep mode. When a predetermined value is exceeded, the sleep mode can be switched to a less power-saving mode, and the demodulator 2930 is activated for demodulation. At the same time, the rest of the transmitter 110 is still off. Assuming that the demodulation transformer 2930 considers that the received signal does not contain a beacon signal, after a period of time, the demodulation transformer 2930 can be turned off, and the power saving mode enters a more power-saving sleep mode. Conversely, when the demodulation transformer 2930 considers that the received signal contains a beacon signal, the demodulation transformer 2930 can wake up other portions of the transmitter 110 to cause the transmitter 110 to Convert from energy saving mode to normal working mode.

Now returning to the embodiment of Figure 9A, after the delay time of the L0 length Thereafter, the transmitter 110 issues an electrical signal during the T0 period and the T1 period, respectively. Between these two time periods T0 and T1, there may be a delay time of L1 length. The two periods T0 and T1 may be of equal length or unequal length. T0 and T1 can be collectively referred to as a signal frame. The touch processing device 130 detects the electrical signal emitted by the transmitter 110 during the two periods T0 and T1. Then, after the optional delay time of the L2 length, the touch processing device 130 performs an optional other mode detection step, such as the previously mentioned capacitive detection mode, for detecting the non-active pen or finger.

The present invention does not limit the lengths of the delay times L0, L1, and L2 described above. Can be zero, or any length of time. The length of the three can be related or not. In an embodiment, among the various periods shown in FIG. A, only the T0 and T1 periods in the signal frame are necessary, and other periods or steps are optional.

Please refer to Table 1, which is a telecommunications device 110 according to an embodiment of the present invention. A schematic diagram of the change of the number. In Table 1, the transmitter 110 is in a floating state, that is, the force sensor does not feel any pressure. Since the pen tip segment 230 of the transmitter 110 does not touch the touch panel/screen 120, in order to enhance the signal, in the embodiment of Table 1, the first signal source 211 and the second signal source 212 are in the same period. Among them, the same frequency group Fx is generated. For example, in the state in which the pen button is pressed, the first signal source 211 and the second signal source 212 are both emitted during the T0 period. The frequency group F0, and in the T1 period, the first signal source 211 and the second signal source 212 both transmit the frequency group F1. When the touch processing device 130 detects the frequency group F0 in the T0 period and detects the frequency group F1 in the T1 period, it can be inferred that the pen button of the transmitter 110 in the floating state is pressed.

The aforementioned frequency group Fx includes signals of at least one frequency, and can be mutually exchange. For example, the frequency group F0 may include f0 and f3 frequencies, the frequency group F1 may include f1 and f4 frequencies, and the frequency group F2 may include f2 and f5 frequencies, and the like. Whether receiving the f0 frequency or the f3 frequency, the touch processing device 130 regards the frequency group F0 as being received.

In another embodiment, the transmitter 110 in the floating state does not necessarily need two Both sources 211 and 212 emit signals of the same frequency group. The present invention is not limited to the first embodiment as the only embodiment. In addition, the transmitter 110 can also include more buttons or sensors, and the invention is not limited to only two buttons.

Please refer to Table 2, which is a telecommunications device 110 according to an embodiment of the present invention. A schematic diagram of the change of the number. In Table 2, the tip portion 230 of the transmitter 110 is in a contact state, that is, the force sensor senses the pressure.

In the embodiment shown in FIG. A, the following is the press of the pen button SWB. Happening. During the T0 period, the signal source of the first signal source 211 is grounded, and the second signal source 212 emits the frequency group F0, so that the electrical signal of the transmitter 110 is only sent by the second signal source 212 during the T0 period. Frequency group F0. During the T1 period, the signal source of the second signal source 212 is grounded, and the first signal source 211 emits a frequency group F1. Also, since the impedance value of the first capacitor 321 is changed at the time of contact, the degree of stress of the nib segment 230 can be calculated from the intensity ratio of the F0 and F1 signals respectively received during the T0 and T1 periods. In addition, since the touch processing device 130 detects the F0 signal during the T0 period and detects the F1 signal during the T1 period, it can be inferred that the pen button is pressed.

In the embodiment shown in FIG. 4B, the following is the press of the pen button SWB. Happening. During the T0 period, the signal source of the first signal source 211 is grounded, the second signal source 212 emits a frequency group F0, and the second capacitor 322 is connected in parallel with the sheath capacitor 442. Although the electrical signal of the transmitter 110 has only the frequency group F0 emitted by the second signal source 212 during the T0 period, its signal strength is different from the case where the pen button SWB is not pressed. During the T1 period, the signal source of the second signal source 212 is grounded, and the first signal source 211 emits the frequency group F1. Also, since the impedance value of the first capacitor 321 changes during the contact, it may be respectively according to the T0 and T1 periods. The intensity ratio of the received F0 and F1 signals is used to calculate the force of the stylus. In addition, since the touch processing device 130 detects the F0 signal during the T0 period and detects the F1 signal during the T1 period, it can be inferred that the pen button is pressed.

Please refer to Table 3, which is a telecommunications device 110 according to an embodiment of the present invention. A schematic diagram of the change of the number. In this embodiment, it is possible to know which buttons are pressed according to the frequency group.

Table 4

Please refer to Table 4, which is a transmitter 110 according to an embodiment of the present invention. A schematic diagram of a modulation of an electrical signal. In this embodiment, it is possible to know which buttons are pressed according to the frequency group, and also rely on the ratio of the signal strengths received by the T0 and T1 periods to estimate the degree of force of the stylus tip.

Please refer to FIG. 24B, which is a transmitter according to an embodiment of the present invention. A timing diagram of the signal modulation of 110. It is another variation of the embodiment of Figure 9A. The difference from the ninth A picture is that the step of noise detection is performed after the T1 period. Then, perform other mode detection.

Please refer to FIG. C, which is a transmitter according to an embodiment of the present invention. A timing diagram of the signal modulation of 110. The signal modulation of the ninth C diagram can be applied to the transmitter 110 shown in the fifth figure. Another function of adding the ring electrode 550 is to enhance the signal strength when the active pen is suspended, so as to facilitate the touch panel detection. The range of the pen's suspension.

The signal of the ninth C is modulated to be sent when the transmitter 110 is in a floating state. number. In this state, the signal frame sent by the transmitter 110 contains only a single R period. During this R period, the ring electrode 550 and the tip section 230 can simultaneously emit electrical signals. In an embodiment, the electrical signals may be from the same source, having the same frequency and/or modulation. For example, the ring electrode and the nib all emit an electrical signal of the third signal source 513. For example, the ring electrode 550 and the pen tip segment 230 can collectively emit electrical signals of the first, second, and third signal sources in order to utilize the maximum power of each of the signal sources, respectively. The touch processing device 130 is in the R period, It is only necessary to detect the electrical signal emitted by the ring electrode 550, and it can be known that the transmitter 110 is suspended at a certain position of the touch panel 120. If the electrical signals emitted by the ring electrode 550 and the pen tip segment 230 are from the same signal source, or have the same frequency group, the signal intensity will be the largest, so that the touch panel can detect the stylus suspension range to the maximum. . Within the R period of another embodiment, it is also possible to emit an electrical signal only through the ring electrode 550.

Please refer to the ninth D diagram, which is a transmitter according to an embodiment of the present invention. A timing diagram of the signal modulation of 110. The signal modulation of the ninth D diagram can be applied to the transmitter 110 shown in the fifth figure. In the ninth C picture, a delay time or blank period L1 is included after the R period, and then the touch panel performs other forms of detection. The embodiment of the ninth D diagram has a longer time in the L1 period than in the ninth C diagram. The ninth D map is compared with the embodiment of the ninth E diagram, and the length of the L1 period is equal to the sum of the L1 period, the T0 period, the L2 period, the T1 period, and the T3 period of the ninth E map. Therefore, if the touch processing device 130 of the ninth D diagram does not detect any electrical signal during the fixed length L1 period, it can be known that the transmitter 110 is in a floating state.

Please refer to FIG. 9E, which is a transmitter according to an embodiment of the present invention. A timing diagram of the signal modulation of 110. The signal modulation of the ninth E diagram can be applied to the transmitter 110 shown in the fifth figure. The ninth E-picture embodiment can be said to add the front of the signal frame of the ninth embodiment to the R period. In this embodiment, regardless of whether the nib segment 230 is depressed, the transmitter 110 uniformly emits an electrical signal from the nib during the T0 period and the T1 period, thereby saving some logic circuit design. However, compared to the embodiments of the ninth C and ninth D diagrams, the embodiment of the ninth E diagram wastes electrical signal power emitted during the T0 period and the T1 period. On the other hand, the touch processing device 130 does not need to detect in the R period. As long as the electrical signal emitted by the nib segment 230 can be detected in the T0 period and the T1 period, the nib segment 230 can be known. Is it under pressure to know how to send a letter? Whether the device 110 is in a floating state.

Please refer to the ninth F diagram, which is a transmitter 110 according to an embodiment of the invention. A timing diagram of the signal modulation. The signal modulation of the ninth F map can be applied to the transmitter 110 shown in the fifth figure. In the embodiment of the ninth E diagram, the proportional relationship between the R period and the length of the T0 period and the T1 period is not limited. In the embodiment of the ninth F diagram, the length ratio of the R period to the T0 period and the T1 period is 1:2:4. As such, it is assumed that the touch processing device 130 can perform N samples in a unit time, and N is a positive integer. Therefore, in the R period and the T0 period and the T1 period, the touch panel can perform N: 2N: 4N sampling. The present invention does not limit the length ratio of the three periods. For example, the period in which the power signal is most powerful can be kept for a minimum unit time, and the period in which the power of the electrical signal is minimized is continued for the longest unit time. For example, the length ratio can be 1:3:2, or 1:2:3, etc., depending on the design. Although in the above-mentioned pages, only the modulation of the two periods T0 and T1 is mentioned, the present invention is not limited to the modulation of two periods, but can be applied to the modulation of more periods.

In the previous ninth to fifth ninth F, the pressure applied to the nib segment 230 The value can be estimated based on the intensity ratio of different signals received during different time periods. In some embodiments of the present application, the pressure value of the nib segment 230 may not be measured in the transmitter 110, so that the electrical signal emitted by the nib segment 230 reflects the pressure value it is subjected to.

In other embodiments, the transmitter 110 can include the measurement pen tip segment 230 The pressure value device can be implemented by using the sixth or eighth figure, or by using a pressure gauge, a capacitor for measuring pressure, a resistor, an inductor, and an analog digital converter. The present invention is not limited to the apparatus used therein, and only a digital representative value or a pressure digital value of the pressure applied to the nib section 230 can be measured inside the transmitter 110.

According to the design accuracy requirements, the above pressure digital values can be variously accurate. degree. Simple can include ten kinds of precision or resolution, and complex can be more than one thousand kinds of precision, and the present invention does not limit the accuracy or resolution of the pressure digital value. In one embodiment, the pressure digital value may comprise 256 precisions; in another embodiment, 16 precisions may be included; in a further embodiment, 1024 precisions may be included.

The above accuracy can be expressed in a variety of ways, for example, the most intuitive The decimal method. Assuming that the pressure digital value contains 256 kinds of precision, it can be represented by three decimal digits, or by two hexadecimal digits, or by eight binary digits. Assuming that the pressure digital value contains 512 kinds of precision, it can be represented by three decimal digits, or by three hexadecimal digits. The invention does not limit the representation of the pressure digital value.

A feature of the invention is that the sender 110 employs at least one or more time periods To generate an electrical signal indicative of the pressure value. It should be noted that the electrical signal emitted here does not need to be a conventional square wave signal, and may be a sine wave signal or other kinds of signals. The invention does not limit whether the electrical signal has any coding or modulation form, and only the touch processing device 130 can detect that the transmitter 110 has an electrical signal or does not emit an electrical signal. Briefly, the touch processing device 130 only determines whether the transmitter 110 emits an electrical signal regardless of the form of its electrical signal encoding or modulation. Further, when the touch processing device 130 determines that the transmitter 110 emits an electrical signal, it can determine the start time and length of time during which the electrical signal is emitted.

In an embodiment, as shown in FIG. 9A, the transmitter 110 adopts T0 and T1. An electrical signal indicating a pressure value is issued during a period of time. Assuming that the pressure digital value contains 256 kinds of precision, which can be represented by two hexadecimal digits, the two digits can be represented by the electrical signals of the T0 and T1 periods, respectively. You can use the electrical signal of the T0 period to indicate the higher bit, or you can use T1. The electrical signal of the time period indicates the lower bit. In other words, the present invention does not limit the order of the number of bits represented by each time period, and may be a Big Endian or a Little Endian.

Assuming that the T0 period is used to represent the number of hexadecimal digits, then telecommunications can be used. The number and the form of the unsent electrical signal indicate the number of bits in a hexadecimal. In an embodiment, the T0 period can be cut into fifteen sub-periods. When the transmitter 110 sends an electrical signal for fifteen sub-periods, it is indicated as 15. When the transmitter does not emit an electrical signal during these fifteen periods, it is represented as 0. When there are seven time periods in these fifteen time periods, when it is an electrical signal, it is expressed as 7. For example, 001111111000000 can be expressed as 7,101010101010100 can also be expressed as 70000000011111111 or can be expressed as 7. When there are twelve time periods in which the electrical signal is sent out, it is expressed as 12. In this embodiment, the present invention does not limit whether the period in which the electrical signal is emitted is continuous, or whether separation is required, nor does it limit the sub-period position or order in which the electrical signal is emitted. As long as the touch processing device 130 is capable of calculating an electrical signal for several sub-periods when it is received, a certain number of bits of the pressure digital value can be interpreted.

In an embodiment, the various time periods of the present invention do not necessarily all have the same length. ratio Fang said that when using three decimal values to represent the pressure digit value of 256, the period representing the hundred digits only requires three sub-periods, which can represent three possibilities of 0, 1, and 2. If the decimal value is used to represent the pressure digital value 512, the time period indicating the hundred digits needs to be divided into five sub-periods, that is, three possibilities of 0 to 5 can be expressed. In this case, the time period that represents the hundred digits will be shorter than the other two periods.

In another embodiment, a certain period of time representing a 16-bit value can be cut to a ratio Fifteen more sub-periods to add redundancy code, error detecting and/or correcting code, and/or check code. Can also make the value of the 10-digit value A certain period of time is cut into more than nine sub-periods to add a fault-tolerant code, an error correction code, or a check code. In an embodiment, in each of the time periods, an encoded form of asynchronous transmission may be employed. In summary, the present invention does not limit the form of modulation and demodulation.

In the present application, the previous related descriptions of Figures 9A through IXF, except In addition to the different signal modulation methods, the rest can be applied to embodiments in which the digital signal is used to transmit the pressure value. For example, the delay time of the L0 period, the L1 period, the L2 period, and the L3 period described above may be zero or an arbitrary length.

As shown in the ninth D, when the nib segment 230 is not in contact with any object, the sender When the 110 is in the floating state, the transmitter 110 does not emit any signal during the L1 period. The touch processing device 130 detects the transmitter 110 that is in suspension and sends a signal through the R period detected by the transmitter. As shown in FIG. 9E, when the nib segment 230 contacts the touch panel 120, the touch processing device 130 of the ninth E diagram is at L1, T0, L2, and T1 corresponding to the L1 period of the ninth D map. The pressure digital value emitted by the transmitter 110 is detected during the L3 period. Although only the embodiments of the T0 period and the T1 period are shown in the ninth A to ninth F diagrams, the present application can be applied to the pressure digit value transmission period of at least one period or three or more periods.

In the present application, when the sender 110 sends out a pressure through a plurality of time periods When the digit value is a digital signal, the transmitter 110 can adopt different modulation methods during these periods. For example, when 256 or 512 kinds of pressure digital values have been mentioned before, the time period indicating the hundred digits has different modulation mode and time from the other two time periods. In other embodiments, the period representing the hundred digits and the other two periods may also have the same length of modulation time, but are modulated in different ways.

Although in the foregoing embodiments of the present application, the pen tip segment 230 is subjected to The pressure value is the subject of electrical signal transmission, but the application is not limited thereto. The digital value received by any sensor having multiple possible states on the transmitter 110 can be transmitted in this manner. For example, when the sender 110 has two buttons, then the two buttons can contain four states. Accordingly, the transmitter 110 can emit an electrical signal representing 0 to 3 during a period of time to indicate the sensing of the buttons. In another example, when the sender 110 has three buttons, then the three buttons can contain eight states. Accordingly, the transmitter 110 can signal a 0 to 7 during a period of time to indicate the sensing of the buttons. In an embodiment, the period during which the state of the buttons is transmitted may be the above-mentioned transmitter detecting R period. When the digit value indicating the button state is transmitted in the R period, the touch processing device 130 can also know the button state of the sender 110 while detecting the in-flight transmitter 110.

In an embodiment, the digit value transmitted during the R period can pass through the nib segment The light is emitted from the ring electrode 550, and can also be emitted through the pen tip segment 230 and the ring electrode 550 to facilitate the touch processing device 130 to detect. The description thereof can refer to the embodiments of the twenty-fifth and twenty-sixth drawings.

In an embodiment, the electrical signal may be grouped by a signal frequency group. A signal that has or has only a single signal frequency. Therefore, the touch sensing device 130 can block the frequency group or the single frequency through the filter or the demodulator, and can detect whether the starter 110 emits an electrical signal. In the ninth to fifth ninth F, the transmitter 110 and/or the touch sensing device 130 can perform the operation of the noise detection. When the transmitter 110 and/or the touch sensing device 130 find that the frequency of the noise is the same as the frequency of the electrical signal, the transmitter 110 can be used to transmit the electrical signal using another frequency group or another frequency. This section can refer to the subsequent related instructions.

The touch processing device 130 can detect the transmitter 110 in a variety of ways. In a In an embodiment, the signals received by the first electrode 121 and the second electrode 122 may be processed using a filter, an integrator, and a comparator. The filter is used to filter out noise at other frequencies, the integrator is used to sample the signal, and the comparator is used to compare whether the sampled result exceeds a preset value. The preset value may be the noise value inside the touch processing device 130 and the noise value frequently received by the touch panel 120. When the sampling result exceeds the preset value, the received signal is greater than the noise value, indicating that the result of the sampling is an electrical signal detected, which may be expressed as 1, otherwise 0. Similarly, the filtering step, the integrating step, and the comparing step may be used to process the signals received by the first electrode 121 and the second electrode 122 to determine whether the sampling result is an detected electrical signal.

In an embodiment, the integrator used may be a dual slope integrator. The integration step used may be a dual slope integration method. In an embodiment, the preset value may be zero or the comparator or comparison step may be omitted.

In another embodiment, the touch processing device 130 can be processed using a demodulation transformer. The signals received from the first electrode 121 and the second electrode 122. Demodulation transformers have a variety of implementations. Briefly, the demodulator can multiply the sampled signal and the desired frequency signal to add up. When the total score is greater than a certain preset value, it indicates that the sampled signal detects the electrical signal. The result is 1, otherwise 0.

In the above embodiments, the respective periods representing the pressure digital value have a fixed length Degree, so the time at which the electrical signal can be transmitted through the transmitter occupies a proportion of the time period to represent a certain value of the pressure digital value. In another embodiment of the present invention, an electrical signal transmission period of an unfixed length may be used instead to represent a certain bit value of the pressure digital value. When the electrical signal is interrupted, the transmission time representing the value of the bit ends, and the next time the electrical signal is transmitted, the next bit value is indicated.

Please refer to the ninth G diagram, which is a transmitter according to an embodiment of the present invention. A timing diagram of the signal modulation of 110. The signal modulation of the ninth G map can be applied to the transmitter 110 shown in the fifth figure. The embodiment of the ninth G diagram can be used to employ the length of the two electrical signal transmission times of D0 and D1 to represent the digital pressure values including the two bit values, respectively. As shown in the figure, the D0 electrical signal transmission time length is 4 units, and the D1 electrical signal transmission time length is 8 units. Assuming that it is expressed in decimal, the pressure value can be interpreted as 48.

In this embodiment, the R period is optional. When the sender 110 must be in the R period When the electrical signal is sent for the touch processing device 130 to detect its position, and the R period is used to indicate the sensing state of other sensors, the sensing state digit values of the sensors cannot be encoded from 0, or cannot Contains 0, that is, it cannot transmit electrical signals. For example, when the sender 110 is to transmit the digit status values of the two buttons, in one embodiment, the four digit status values can be 1, 2, 3, 4. In another embodiment, it can be expressed as 2, 3, 4, 5. In other embodiments, it can be expressed as 2, 4, 6, 8. In other embodiments, it can be expressed as 1, 3, 5, 7. The transmitter 110 transmits electrical signals of several unit lengths in accordance with the digital status values described above.

Similarly, when the D0 and D1 electrical signal transmission periods are used to represent the digital value, To adopt a non-zero length modulation. For example, a decimal digit value can be expressed as 1~10 or 2~11 instead of 0~9. A hexadecimal digit value can be expressed as 1~16 or 2~17 instead of 0~15. For example, when the transmitter 110 is to issue a pressure digital value of the representation 8, an electrical signal of a length of time (ie, a D0 period) may be issued first, and after the electrical signal is stopped, an electrical signal of nine lengths of time may be emitted ( That is, D1 period).

As shown in the ninth G diagram, the period during which the electrical signal is temporarily suspended between D0 and D1 is called L2. The length of the L2 period can be a preset value, such as two unit time lengths. this invention The length of time during which the electrical signals are temporarily suspended between the respective time periods is not limited, and the lengths of these pause periods may be the same or different.

Please refer to the ninth H diagram, which is a transmitter according to an embodiment of the present invention. A timing diagram of the signal modulation of 110. The signal modulation of the ninth H picture can be applied to the transmitter 110 shown in the fifth figure. In this embodiment, the R, D0, D1, and D2 periods used by the transmitter 110 to transmit electrical signals are all indefinite lengths. The touch processing device 130 determines the digital sensed value of each sensor on the transmitter 110 according to the length of time of the detected electrical signal. As previously mentioned, the transmitter 110 transmits electrical signals during the R, D0, D1, D2 periods, and the present invention does not limit the modulation of the electrical signals.

In the embodiment shown in the ninth G diagram and the ninth diagram, the transmitter 110 is based on a The length of time that a segment continuously transmits an electrical signal to represent a certain value. This value can be used to indicate a certain number of digits of a carry system for indicating the digital sensed value of a sensor on the transmitter 110.

Please refer to FIG. 1I, which is a transmitter 110 according to an embodiment of the invention. A timing diagram of the signal modulation. The signal modulation of the ninth I diagram can be applied to the transmitter 110 shown in the fifth figure. In this embodiment, the F0, F1, and F2 periods of three fixed time lengths are respectively used to indicate three digits of a carry system. As shown in FIG. 1I, the three time periods may have the same length of time or may have different lengths of time.

In this embodiment, the transmitter 110 uses a signal of a certain frequency to indicate a certain A certain number of digits of the carry system is used to indicate the digital sensed value of a sensor on the transmitter 110. In an embodiment, the frequency of the signal may be a Pulse Repetition Frequency (PRF). For example, a certain pulse repetition frequency PRFx is used as a base for representing 0. N-1 is represented by its multiple PRFxN. In addition, it is also possible that its score 1/PRFxN represents N-1. In addition, it is also possible to use a look-up table instead of a multiple to indicate a certain number of digits in a carry system. The invention is not limited to whether there is a correlation between two pulse repetition frequencies representing two values. Since the pulse repetition frequency is the number of pulses emitted during a certain period of time, regardless of the length of the F0, F1, and F2 periods, the pulse repetition frequency of the signals in these periods can be calculated as long as the sampling rate of the touch processing device 130 is high enough. .

Similarly, the transmitter 110 can sense the values of other sensors in the same shape. By modulating the pulse repetition frequency of the R period, the touch processing device 130 can learn the sensing values of other sensors by the pulse repetition frequency of the R period. The length of the R period may be the same as or different from other periods.

In an embodiment, the transmitter 110 can be strong when the nib is not in contact. A relatively large electrical signal, and when the tip of the pen is in contact, emits a less powerful electrical signal. Accordingly, the touch processing device 130 can have a greater probability of detecting the transmitter 110 suspended above the touch panel 120. Moreover, after the transmitter 110 contacts the touch panel 120, the energy consumed by the transmitter 110 can be saved.

For example, in the embodiment of the ninth C and D diagrams, that is, the nib segment 230 is not touched. At the time, the electrical signal emitted during the R period may be greater than the electrical signal emitted during the L1 period corresponding to the T0 period and the T1 period. For example, during the R period, the electrical signals emitted by the nib segment 230 and the ring electrode 550 are from the first signal source 211, the second signal source 212, and the third signal source 513. Therefore, the electrical signal emitted by the R period is the sum of the outputs of the three signal sources 211, 212 and 513.

In the embodiment of FIG. 9A, Table 1 is that the transmitter 110 is in a floating state. The output power to the first signal source 211 and the second signal source 212 is utilized. Table 2 shows that the output power of the first signal source 211 or the second signal source 212 is utilized only during the T0 period and the T1 period when the transmitter 110 is in the contact state. Therefore, the transmitter 110 can emit a strong intensity when the pen tip is not in contact. An electrical signal that emits a less intense electrical signal when the nib is in contact.

Similarly, Table 3 uses the first signal when the transmitter 110 is in the floating state. The output power of source 211 and second signal source 212. Table 4 shows that the output power of the first signal source 211 or the second signal source 212 is utilized only during the T0 period and the T1 period when the transmitter 110 is in the contact state. Therefore, the transmitter 110 can emit a strong electrical signal when the pen tip is not in contact, and emit a less powerful electrical signal when the pen tip is in contact.

Why do you want to add noise detection to the embodiments in Figures 9A through IXI? Steps and time periods are shown in the tenth figure, which is a schematic diagram of noise propagation according to an embodiment of the invention. In the tenth figure, the electronic system 100 where the touch panel/screen 120 is located will emit noise of f0 frequency, and the f0 frequency is exactly one frequency of the frequency group F0. It is assumed that the frequency group F0 also contains another f3 frequency. When the user holds the electronic system 100, the noise of the f0 frequency will be transmitted to the touch panel/screen 120 through the user's finger. If the step of the noise detection is not performed, the touch panel/screen 120 may mistake the f0 frequency signal transmitted by the finger as the electrical signal sent by the transmitter 110 during the period of the signal frame. Therefore, if the noise of the f0 frequency is detected in advance, the signal source of the f0 frequency can be filtered out during the period of the signal frame.

It is assumed that the transmitter 110 has an automatic frequency conversion function, and when the transmitter 110 detects itself The noise of the f0 frequency is sent to the touch panel/screen 120, and the other f3 frequency of the same frequency group F0 is automatically changed. In the period of the signal frame, the touch processing device 130 detects the f3 frequency from the transmitter 110 and the f0 frequency from the finger, thereby causing confusion. Therefore, as in the embodiment shown in FIG. BB, a step of noise detection is performed in the T1 period or after the signal frame in the event of confusion. Since the transmitter 110 has stopped transmitting the signal of the f3 frequency, the finger and the electronic system 100 continue to emit noise at the f0 frequency. The touch processing device 130 can infer that in the original Among the signals detected during the signal frame period, the signal having the f3 frequency is the signal actually coming from the transmitter 110.

In an embodiment of the invention, the transmitter 110 receives the touch panel 120 from the touch panel 120. The beacon signal and an electrical signal is sent to the touch panel 120. On the other hand, the touch panel 120 receives an electrical signal from the transmitter 110 and emits a beacon signal to the transmitter 110. The transmitter 110 and the touch panel 120 can be regarded as two transceivers of a wireless communication system, and can transmit and receive signals. In a wireless communication system, receiving an interference signal or not receiving a signal is a situation that the transceiver must consider when receiving.

In an embodiment, when the transmitter 110 is too far from the touch panel 120, When the transmitter 110 cannot receive the beacon signal from the touch panel 120, the transmitter 110 stops transmitting the electrical signal. The touch processing device 130 does not detect the electrical signal sent by the transmitter 110 after transmitting the beacon signal, and may enter the power saving mode, suspend transmitting the beacon signal, or reduce the frequency of transmitting the beacon signal.

The above beacon signal can have multiple frequencies and specific modulation methods, such as It is a modulation method such as amplitude shift keying (ASK), quadrature phase shift keying (QPSK) or binary phase shift keying (BPSK). The transmitter 110 can determine whether or not the noise is interfered according to a given frequency and modulation mode. For example, if the signal demodulated by the transmitter 110 demodulates not only the previously defined signal but also other signals, the transmitter 110 can consider the beacon signal to be interfered. In other examples, the demodulated signal includes only a portion of the previously defined signal and does not include additional portions, and the transmitter 110 may also consider the beacon signal to be interfered. Since the receiving party judges that the signal to be received is interfered in the wireless communication system, it is a well-known technique of those skilled in the art, and therefore it is not enumerated here. The invention also does not limit how the sender 110 determines The method by which the beacon signal is disturbed. Similarly, the present invention recognizes many modulation patterns of electrical signals, and the present invention does not limit how the touch processing device 130 determines that electrical signals are interfered.

In an embodiment, when the transceiver determines that the signal to be received is interfered, It will automatically switch to another frequency to receive the signal.

Please refer to FIG. 34A, which is a touch according to an embodiment of the invention. Schematic diagram of the system's interference processing flow. Assuming that the beacon signal can be one of two frequencies, the two frequencies are referred to as the A frequency and the B frequency, respectively. In step 3402, the touch processing device 130 emits a beacon signal at the A frequency. Next, as in step 3404, when the transmitter 110 is scheduled to receive the beacon signal of the A frequency and is found to be subject to interference, the transmitter 110 does not emit an electrical signal and instead receives the beacon signal of the B frequency. In optional step 3406, the touch processing device 130 emits one or more beacon signals of the A frequency, but does not receive the electrical signal. Then, in step 3408, the touch processing device 130 changes the beacon signal of the B frequency. The transmitter 110 can then successfully receive the beacon signal of the B frequency and, in turn, issue an electrical signal in step 3410.

Since the touch processing device 130 does not receive the electrical signal sent by the sender 110, This judges the frequency at which the beacon signal emitted by the beacon is disturbed and the beacon signal is replaced. Another possible reason is that since the sender 110 is no longer in the range of receiving the beacon signal, the touch processing device 130 may pause the beacon signal after the replacement of all possible frequencies, or extend the interval between the beacon signals to Save power.

Similarly, please refer to the thirty-fourth B diagram, which is an implementation according to the present invention. A schematic diagram of the interference processing flow of the touch system of the example. Assuming that the beacon signal can be one of three frequencies, the three frequencies are referred to as the A frequency, the B frequency, and the J frequency, respectively. The A frequency and the B frequency are normal beacon signal frequencies, and the J frequency is a special alarm frequency for indicating The electrical signal received by the control processing device 130 is subject to interference. The electrical signal can be one of three frequencies, and the three frequencies are referred to as the X frequency, the Y frequency, and the Z frequency, respectively.

In step 3412, the touch processing device 130 emits a beacon signal at the A frequency. Next, in step 3414, the transmitter 110 that successfully receives the A-frequency beacon signal transmits an electrical signal at the X frequency. When the touch processing device 130 determines in step 3416 that the electrical signal of the X frequency is disturbed. Then, in step 3418, the touch processing device 130 emits a beacon signal at the J frequency, indicating that the electrical signal of the X frequency is interfered. When the transmitter 110 does not receive the beacon signal of the A frequency, then in step 3422, the beacon signal of the B frequency is received instead. In step 3422, the touch processing device 130 continues to emit a beacon signal at the J frequency, indicating that the electrical signal at the X frequency is disturbed. When the transmitter 110 also does not receive the beacon signal of the B frequency, then in step 3424, the beacon signal of the J frequency is received instead. In step 3426, after the beacon signal of the J frequency sent by the touch processing device 130 is successfully received by the transmitter 110, the transmitter 110 then changes the transmission frequency of the electrical signal from the X frequency to the Y in step 3428. Frequency, and an electrical signal of the Y frequency is transmitted in step 3430.

In an embodiment, as shown in FIG. 34B, in step 3432, The signaler 110 converts the frequency of the beacon signal to be received from the J frequency back to the original A frequency. Since the electrical signal of the Y frequency is not disturbed, the touch processing device 130 will not emit the beacon signal at the J frequency, and in step 3434, the original A frequency beacon signal is transmitted. The transmitter 110, which successfully receives the A-frequency beacon signal, then sends an electrical signal at a new Y frequency in step 3436. The touch processing device 130 smoothly utilizes the beacon signal of the J frequency to notify the transmitter 110 of the frequency of replacing the electrical signal.

In another embodiment, the sender 110 is not necessarily as described in step 3432. The received beacon signal frequency is converted back to the original A frequency by the J frequency. Instead, it continues to detect the beacon signal of the J frequency. However, since the touch processing device 130 does not emit the beacon signal of the J frequency, the transmitter 110 is late. The beacon signal of the J frequency is not received late and enters the power saving mode. Upon restart, it automatically returns to the state of receiving the A-frequency beacon signal.

In another embodiment, it is assumed that the electrical signal of the Y frequency is still interfered. The control processing device 130 also emits a beacon signal of the J frequency. When the transmitter 110 receives the beacon signal of the J frequency again by automatically changing the mechanism of receiving the frequency of the beacon signal, the frequency of the electrical signal is again converted from the Y frequency to the Z frequency.

In short, when the touch processing device 130 determines that the electrical signal of the received frequency is When the interference is reached, the transmitter 110 can be notified to change the frequency of the electrical signal by emitting a special frequency or a special tone-changing beacon signal.

In an embodiment, the transceiver can actively scan the interfered channel first, and then The frequency of transmitting and receiving signals is determined in the order in which both parties are aware of the communication.

Please refer to FIG. 34C, which is a touch according to an embodiment of the invention. Schematic diagram of the system's interference processing flow. In this embodiment, the possible frequencies of the beacon signal include the A frequency and the B frequency, and the frequency of the electrical signal includes the X frequency, the Y frequency, and the Z frequency. Therefore, the two form a combination of six, assuming that they are arranged in the order of AX, AY, AZ, BX, BY, BZ. The sender 110 and the touch processing device 130 perform scanning interference steps in steps 3440 and 3442, respectively, for example, scanning the possible interference frequency of the beacon signal, and then scanning the possible interference frequency of the electrical signal, that is, A, B, and X. , Y, Z frequency sequence scanning. In this embodiment, it is assumed that the sender 110 and the touch processing device 130 respectively detect that the A and X frequencies have interference signals or noise, and then delete the four combinations of the two interfered frequencies according to the foregoing order. That is, only the combination of BY and BZ is left. Since the order of the BY combination is higher than the BZ combination, the two parties have selected the BY combination in steps 3440 and 3442, respectively. In other words, the touch processing device 130 prepares to generate a beacon signal of the B frequency and prepares Receiving an electrical signal of the Y frequency. The transmitter 110 is ready to receive the beacon signal of the B frequency and is ready to emit an electrical signal of the Y frequency. Accordingly, the touch processing device 130 sends a beacon signal of the B frequency in step 3444, and the transmitter 110 then sends an electrical signal of the Y frequency in step 3446.

In some cases, for example, the source of the interference is different for the distance between the two parties, causing the transmission The interfered frequencies obtained by the active scanning of the touch device 130 and the touch processing device 130 are not necessarily the same. For example, the transmitter 110 only scans the interference signal of the A frequency, and the touch processing device 130 only scans the interference signal of the X frequency. In this case, the highest priority combination obtained by the sender 110 is BX, and the highest priority combination obtained by the touch processing device 130 is AY. Nevertheless, the two rely on the aforementioned mechanism for automatically changing the receiving frequency and transmitting the J-frequency beacon signal, so that the final communication frequency can be adjusted to the BY combination.

In an embodiment, in order to speed up the above process, the transmitter can be detected first. The frequency of the interference, however, the noise transmitted by the interfered frequency is detected by the other party. Please refer to FIG. 34D, which is a schematic diagram of an interference processing flow of a touch system according to an embodiment of the invention. The difference from the embodiment of the thirty-fourth C is that the transmitter 110 scans the interference signal of the A frequency in step 3450, so that the noise of the A frequency is sent in step 3456 to cause the touch processing device 130 to detect. In contrast, the touch processing device 130 scans the X-frequency interference signal in step 3452, and then sends an X-frequency noise to the transmitter 110 for detection in step 3454. In this way, after the detection step ends, both parties scan the A and X frequencies for interference signals or noise. Therefore, as in the embodiment of the thirty-fourth C diagram, both sides select the BY combination indiscriminately or independently, and repeat steps 3444 and 3446.

Although in the thirty-fourth D picture, only two scanning steps 3450 are depicted. 3452, however, in an actual environment, active scanning may not only scan all frequencies once. It is possible to perform two or more scans to avoid missing the signal of the interference frequency that the other party intentionally transmitted.

In addition to this, although in the embodiment shown in the thirty-fourth D, two sweeps Steps 3450 and 3452 are both started simultaneously and ended at the same time, but the two scanning steps may not start at the same time and end at different times. The time taken by the two scanning steps does not necessarily need to be equal, and the number of scanning frequencies may not be Wait. Although in some cases, the opponent may miss the signal of the intentionally transmitted interference frequency. However, in most cases, it is still possible to delete more interference frequency combinations, so that both parties can adjust to the uninterrupted frequency for communication.

In the foregoing embodiments of the thirty-fourth C diagram and the thirty-fourth diagram, both parties have There is an ability to actively scan, especially in the embodiment of the thirty-fourth D-D diagram, both of which have the ability to actively signal the interfered frequency, but the invention does not limit the ability of both parties to be equal. In an embodiment, the sender 110 may have the ability to actively scan and actively signal the interfered frequency, and the touch processing device 130 may only have the ability to actively scan. In this embodiment, although the touch processing device 130 lacks the ability to actively emit a signal of the interfered frequency, both of them can have a greater chance of finding both parties faster than the embodiment of the thirty-fourth C-picture. Communication is performed at frequencies that are not disturbed. Conversely, in another embodiment, the touch processing device 130 can have the ability to actively scan and actively emit signals of the interfered frequency, and the transmitter 110 can have only the ability to actively scan. However, the two can still have a greater chance of communicating with the frequency of the uninterrupted frequency more quickly than the embodiment of the thirty-fourth C-picture.

Similarly, when one party to the communication does not have the ability to actively scan, the other party With the ability to actively scan, it is possible to have a greater chance of finding a frequency that is uninterrupted by both parties to communicate more quickly than the embodiments of the thirty-fourth A and thirty-fourth B-pictures.

In the above description of the second figure, the impedance change of the first element 221 is utilized. To adjust the ratio of the signal strength of a plurality of frequencies. Please refer to FIG. 11 , which is a schematic structural diagram of a first capacitor 221 according to another embodiment of the present invention. The impedance of the first capacitor 221 is used to adjust the ratio of the signal strengths of the plurality of frequencies. A conventional capacitive element is formed by two conductive metal plates. Its permittivity C is proportional to the dielectric constant and the area of the metal plate, and inversely proportional to the distance between the metal plates.

One of the main spirits of the above embodiments is that the elasticity is utilized by a mechanical structure. The stroke of the nib segment 230 along the axial direction of the transmitter 110 is converted into a direction perpendicular to the axial direction of the transmitter 110 or in an angular direction with the axis of the transmitter 110. By changing the stroke, changing the permittivity of the first capacitor 221 and its corresponding first impedance Z1, and fixing the permittivity of the second capacitor 222 and its corresponding second impedance Z2, thereby changing the first frequency among the electrical signals. The ratio of the intensity M1 of the signal portion of the (group) to the intensity M2 of the signal portion of the second frequency (group).

In the eleventh figure, there are three metal plates that are not in contact with each other. First metal The board 1110 and the second metal plate 1120 form a first capacitor 221, and the second metal plate 1120 and the third metal plate 1130 form a second capacitor 222. In one example, the first metal plate 1110 is formed on a flexible circuit board or printed circuit board having an insulating varnish or another insulating plate on its surface. The second metal plate 1120 and the third metal plate 1130 are formed on two layers of the same circuit board or printed circuit board, and the surface thereof has an insulating varnish or another insulating plate. The second metal plate 1120 is coupled to the front nib segment 230 via an additional circuit. The pen tip is fixed to a lifting element 1140 (such as the bevel device described below), and directly or indirectly lifts part or all of the first metal plate 1110 (or an elastic circuit board or a printed circuit board) according to the displacement of the pen tip segment 230, or causes The portion of the first metal plate 1110 (or the flexible circuit board or printed circuit board) is deformed perpendicular to the axial direction of the transmitter 110, and is collectively referred to as a displacement perpendicular to the axial direction of the stylus in the following description.

Supplying the first metal plate 1110 with an electrical signal of a first frequency (group), supplying the first The three metal plates 1130 have electrical signals of a second frequency (group). Therefore, the second metal plate 1120 induces an electrical signal having a first frequency (group) and a second frequency (group) to be transmitted to the touch panel 120 via the front nib segment 230. When the nib segment 230 is unstressed, the first metal plate 1110 and its associated circuit board do not have a displacement perpendicular to the axial direction of the transmitter 110. However, after the pen tip segment 230 is stressed, due to the bevel device 1140 behind the pen tip segment, the force is converted from a direction parallel to the axis to a direction perpendicular to the axis, causing the circuit board to which the first metal plate 1110 belongs to deform. The displacement, which in turn causes the dielectric constant of the first capacitor 221 to change. Therefore, the permittivity C1 of the first capacitor 221 and the first impedance Z1 also change. After the nib segment 230 is stressed, the second metal plate 1120 and the circuit board to which the third metal plate 1130 belongs are displaced as a whole, so the permittivity C2 and the impedance Z2 of the second capacitor 222 remain unchanged.

Since the circuit board where the first metal plate 1110 is located is squared upward, this embodiment At least one support member 1150 may be included to provide a support force in the opposite direction such that after the force of the nib segment 230 has disappeared, the circuit board on which the first metal plate 1110 is located is restored to its original shape. The support force provided by the support element 1150 can be zero before being deformed.

In an example of the embodiment, the capacitance of the first capacitor 221 and the second capacitor 222 The rate can be designed to be the same. In the case where the permittivity is the same, the dielectric constant, distance, and area of the two capacitors may be the same. Of course, the present invention does not limit the capacitance ratios of the two capacitors 221 and 222, as long as the touch processing device 130 knows the corresponding impedance ratio of the two capacitors of the transmitter 110.

In this embodiment, an inexpensive circuit board or printed circuit board is used instead of Expensive force sensing resistors. Moreover, when the capacitance ratios of the first capacitor 221 and the second capacitor 222 are the same, When the external environment changes, the dielectric constant also changes at the same time, thereby maintaining the proportional preset value. In addition, the transmitter 110 itself does not require an active control element to adjust the ratio of the two impedances Z1 and Z2, and only needs to passively provide an electrical signal, which can save a lot of resources.

In the embodiments of the seventeenth A and B, It is only necessary to feed the drive signals of the same frequency. In other words, it can be applied to the respective embodiments of the seventh A to the seventh D, and the fed driving signal may be the single signal source 714 of the seventh A picture and the seventh B picture, or may be the seventh C picture. The electrical signal obtained by the signal communication unit 771 is used as a signal source, and may be the first electrode 121 and/or the second electrode on the touch panel 120 when the pen tip segment 230 of the seventh D is in close proximity to the touch panel 120. The signal obtained by 122 is used as a signal source.

The three-layer metal plate of Figure 17A and the three-layer metal plate structure of Figure 16A Similarly, the above-described drive signal having a certain frequency is fed into the deformable second metal plate 1120. Through the capacitive effect with the second metal plate 1120, the first metal plate 1110 will have an induced first current value I1 output. Similarly, the third metal plate 1130 outputs an induced second current value I2 through the capacitive effect with the second metal plate 1120.

A first capacitor 221 is formed between the first metal plate 1110 and the second metal plate 1120, A second capacitor 222 is formed between the second metal plate 1120 and the third metal plate 1130. When the second metal plate 1120 is not deformed, the impedance values of the first capacitor 221 and the second capacitor 222 are fixed, so the current quantities I1 and I2 are analyzed, and a proportional value is calculated based on the two current values. When the ratio value is a predetermined value or falls within a predetermined range, it can be known that the second metal plate 1120 is not deformed.

When the second metal plate 1120 is deformed, the first capacitor 221 and the second capacitor 222 The impedance value and the permittivity change. Therefore, a proportional value is calculated according to the two current values I1 and I2, and according to the change of the proportional value, the deformation or the force of the second metal plate 1120 can be reversely pushed back. Accordingly, the method embodiment shown in the eighth figure can be applied.

The above-described drive signal having a certain frequency is fed into the deformable first metal plate 1110. Through the capacitive effect with the first metal plate 1110 The second metal plate 1120 outputs the induced first current value I1. Similarly, the third metal plate 1130 outputs the induced second current value I2 through the capacitive effect with the first metal plate 1110.

A first capacitor 221 is formed between the first metal plate 1110 and the second metal plate 1120, A second capacitor 222 is formed between the first metal plate 1110 and the third metal plate 1130. When the first metal plate 1110 is not deformed, the impedance values of the first capacitor 221 and the second capacitor 222 are fixed, so the current quantities I1 and I2 are analyzed, and a proportional value is calculated based on the two current values. When the ratio value is a predetermined value or falls within a predetermined range, it can be known that the first metal plate 1110 is not deformed.

When the first metal plate 1110 is deformed, the first capacitor 221 and the second capacitor 222 The impedance value and the permittivity change. Therefore, a proportional value is calculated according to the two current values I1 and I2, and according to the change of the proportional value, the deformation or the force of the first metal plate 1110 can be reversely pushed back. Accordingly, the method embodiment shown in the eighth figure can be applied.

Please refer to the eighteenth figure, which is a modification of the embodiment shown in the eleventh figure. First The embodiment shown in the eleventh figure requires the feeding of signals of two frequencies. However, in the embodiment shown in the eighteenth embodiment, as in the embodiments of the seventeenth A and seventeenth B, it is only necessary to feed a drive signal of a certain frequency to the second metal plate 1120, or to feed A signal that does not need to know how many frequencies the feed signal has.

A first capacitor 221 is formed between the first metal plate 1110 and the second metal plate 1120, A second capacitor 222 is formed between the second metal plate 1120 and the third metal plate 1130. Since the distance and dielectric constant of the second metal plate 1120 and the third metal plate 1130 do not change, the capacitance value and impedance of the second capacitor 222 are fixed. When the first metal plate 1110 is not deformed, the impedance values of the first capacitor 221 and the second capacitor 222 are fixed, so the current quantities I1 and I2 are analyzed, and a proportional value is calculated based on the two current values. When the ratio value is a preset value or falls within a preset range, it can be known The first metal plate 1110 of the track is not deformed. However, the permittivity and impedance of the first capacitor 221 may change due to the deformation of the first metal plate. Therefore, when the first metal plate 1110 is deformed by an external force, the first current value I1 may vary. Therefore, the proportional value associated with the current values I1 and I2 also changes, whereby the deformation or stress of the first metal plate 1110 can be reversed. Accordingly, the method embodiment shown in the eighth figure can be applied.

In another embodiment of the invention, the controller or circuit within the transmitter 110 can Therefore, the driving signal of a certain frequency is fed to the second metal plate 1120, and the current quantities I1 and I2 corresponding to the first capacitor 221 and the second capacitor 222 are calculated, and the ratio values of the two are used to calculate the sensing value, thereby Determine the extent to which the tip of the pen is stressed. In other words, by the foregoing first impedance Z1 and second impedance Z2, the present invention provides a pressure sensing capacitor (FSC) that can be used to replace a conventional pressure sensing component, such as a pressure sensing resistor FSR. Provide judgment of stress. The pressure sensing capacitor provided by the invention has the characteristics of low cost and being less susceptible to temperature and humidity. In the foregoing figures, the use of a flexible printed circuit board as a force sensing capacitor is disclosed. One of the features of the present invention is to provide other forms of force sensing capacitance.

Please refer to FIG. 19A, which is the force sensing capacitor of the transmitter 110 and its structure. An exploded view of the center section. Please note that the proportions in Figures 19A through E have been changed to highlight certain parts. In addition, some fixed components are omitted to simplify the description. In the nineteenth A diagram, the leftmost component is a long pole type pen tip or pen tip section 230, and the pen tip portion may be an electrical conductor. For convenience, the nib segment 230 is referred to as the front end of the transmitter 110 or the active pen. When in contact with the front movable member 1971, the nib segment 230 is coupled to the front movable member 1971. The front end movable member 1971 is coupled to the female fastener in the middle of the rear end movable member 1972 by an intermediate male member. In an embodiment, the male and female fasteners can comprise threads. Front movable element 1971 and rear movable element 1972 can be a conductor or a conductive element, such as a metal piece.

Figure 19A includes a housing 1980 that can be included in a ring shape The front and rear movable members 1971 and 1972 described above are housed, and for the sake of simplicity, only a part of the housing 1980 is shown in Fig. 19A. The portion of the housing 1980 adjacent the tip portion 230 is retracted into a neck having a smaller diameter, and the neck portion and the portion of the housing having a larger diameter may include a shoulder portion as a bearing portion. In the nineteenth A diagram, at least one elastic member 1978 is sandwiched between the bearing portion and the front end movable member 1971 for respectively applying the housing 1980 and the front movable member 1971 along the long axis of the pen. force. The elastic element 1978 can be a spring, a spring or other type of resilient element. In an embodiment, unlike the nineteenth A diagram, the elastic element 1978 can surround the movable element 1970 and the neck of the housing 1980.

In another embodiment, the elastic element 1978 can be along the long axis of the pen, respectively The housing 1980 and the rear movable member 1972 are biased. Since the front and rear movable members 1971 and 1972 can be combined into a movable member 1970 by a fastener, the movable member 1970 can be pushed toward the front movable member 1971 or the rear movable member 1972. The nib segment 230, in turn, pushes the nib segment 230 toward the front end.

When the nib segment 230 is biased to the right or to the back in the figure, the bullet will be overcome. The elastic element 1978 compresses the movable element 1970 until a portion of the movable element 1970 contacts the bearing portion of the housing 1980. Accordingly, the present invention provides a design that allows the movable element 1970 to move along the long axis of the pen within the neck of the housing 1980 for one stroke. Likewise, since the movable element 1970 is against the nib segment 230, the nib segment 230 can also be moved along the long axis of the pen to the same stroke. The length of the stroke can vary depending on the design, for example, it can be 1 mm or 0.5 mm. The invention does not limit the length of the stroke.

At the rear end of the rear movable member 1972, there is an insulating film 1973. Insulating film The back end of the 1973 also contains a compressible conductor 1974. In one embodiment, the compressible conductor 1974 can be a conductive rubber or a resilient element of a doped conductor. Since the insulating film 1973 is interposed between the movable element 1970 and the compressible conductor 1974, the movable element 1970, the insulating film 1973, and the compressible conductor 1974 form a capacitor or a force sensing capacitor. The force sensing capacitor provided by the present application may be the first capacitor 221 of the second to fifth figures. In short, the force sensing capacitors provided by the present application can be applied to the various embodiments described above.

The compressible conductor 1974 is attached to a conductor substrate 1975, and the conductor substrate 1975 can be attached to the inner peripheral surface of the housing 1980 by firmware or fasteners. When the movable member 1970 is moved toward the rear end or to the right, since the position of the conductor base 1975 is immobile, the rear movable member 1972 compresses the compressible conductor 1974, causing the capacitance value of the above force sensing capacitor to change.

Due to the shape limitation of the pen, the remaining circuits and battery modules can be located in the conductor The back end of the substrate 1975. In the nineteenth A diagram, these components can be represented by a printed circuit board 1990. As the first end of the force sensing capacitor, the above movable element 1970 is connected to the printed circuit board 1990 through a movable element wire 1977. As the second end of the force sensing capacitor, the conductor base 1975 is connected to the printed circuit board 1990 by a base wire 1976.

The pedestal lead 1976 can also be another resilient element. In some embodiments In contrast to the nineteenth A diagram, the pedestal lead 1976 can surround the conductor pedestal 1975. In another embodiment, the conductor base 1975 is not electrically conductive, and the base conductor 1976 is electrically coupled to the compressible conductor 1974 through the conductor base 1975.

In an embodiment, the manufacturing method of the insulating film 1973 may be the back end The right end plane of the movable member 1972 is immersed in an insulating liquid. After the insulating liquid is dried, An insulating film 1973 is formed on the right end plane of the rear movable member 1972.

Please refer to the twentieth figure, which is the compressible conductor 1974 in Figure 19A. A schematic cross-sectional view of the contact surface with the insulating film 1973. The twenty-fifth diagram contains an embodiment of the contact faces of four compressible conductors 1974 and the insulating film 1973. The embodiment of (a) is the contact surface of the central protrusion, the embodiment of (b) is the contact surface of the single slope, the embodiment of (c) is the central tapered contact surface, and the embodiment of (d) is a plurality of protrusions. Contact surface. The Applicant believes that the invention does not limit the shape of the contact surface.

Although in FIG. 19A, the insulating film 1973 is formed on the movable element 1970. The surface is a flat surface, but the present invention is not limited thereto. The surface may be a contact surface as shown in the twentieth diagram, a central protrusion, a single slope, a central cone shape, or a contact surface with a plurality of protrusions. In other words, in some embodiments, the surfaces of both the compressible conductor 1974 and the insulating film 1973 are not planar.

Please refer to the figure 19B, which is the combination of the structure shown in Figure 19A. A schematic view of the rear section. After combining, the front end movable element 1971 and the rear end movable element 1972 have been combined into a single movable element 1970. The movable element 1970 is coupled to the bearing portion of the housing 1980 by an elastic member 1978. The elastic tension of the elastic member 1978 causes the movable member 1970 to abut the tip end portion 230 toward the front end until the rear end is movable. Element 1972 is placed against the bearing portion of housing 1980. A movable stroke d is left between the movable element 1970 and the housing 1980. At this time, the compressible conductor 1974 is not deformed by compression, and the capacitance value of the force-sensing capacitor is assumed to be a first capacitance value.

Please refer to the nineteenth C diagram, which is the combination of the structure shown in the nineteenth A Another cross-sectional schematic view. Compared with the nineteenth B-picture, since the nib section 230 is subjected to the pressure toward the rear end, it moves toward the rear end. Influenced by the movement of the nib segment 230, the movable element 1970 overcomes the bomb The elastic tension of the element 1978 is moved to the rear end for the entire stroke d until the front movable member 1971 is pressed against the bearing portion of the housing 1980. At this time, the compressible conductor 1974 is subjected to compression by the compression of the movable element 1970 and the insulating film 1973, and the capacitance value of the force sensing capacitor is a second capacitance value which is different from the first capacitance value described above.

Between the end of the stroke shown in Figure 19B and Figure 19C, the movable element The 1970 can also have an infinite number of locations, or the compressible conductor 1974 can have an infinite number of compressions, or the area of the contact surface of the compressible conductor 1974 and the insulating film 1973 can have an infinite number of sizes, a certain position or The degree of compression or the change in the size of the area can change the capacitance value of the force-sensing capacitor.

Please refer to FIG. 19D, which is a transmitter according to an embodiment of the present invention. An exploded view of the center of the force sensing capacitor of 110 and its structure. It differs from the nineteenth B-picture in that the positions of the compressible conductor 1974 and the insulating film 1973 are interchanged. In any event, when the movable member 1970 moves toward the rear end, the compressible conductor 1974 will be deformed by the compression of the insulating film 1973 and the conductor base 1975. Thereby, the capacitance value of the force sensing capacitor can also be changed.

Please refer to FIG. 19E, which is a transmitter according to an embodiment of the present invention. An exploded view of the center of the force sensing capacitor of 110 and its structure. The difference between the nineteenth E and the nineteenth B is that the right end of the rear movable member 1972 is no longer an insulating film 1973 but a compressible dielectric material 1979. For example, insulating rubber, plastic, foam, etc. The conductor connected to the conductor base 1975 is changed to an incompressible conductor, such as a metal block or graphite. When the pressure of the movable member 1970 is applied, the thickness of the compressible insulating material 1979 becomes small, and the distance between the movable member 1970 and the conductor becomes small, so that the capacitance value of the force sensing capacitor changes. From the perspective of production cost, the conductor of the nineteenth E It is more expensive than the compressible conductor 1974 of Figure 19A.

In a variation of the nineteenth E embodiment, the conductor can be compressed The contact faces of the insulating material 1979 are formed into contact faces of various shapes as shown in the twentieth diagram. In another variation, the contact surface of the compressible insulating material 1979 with the conductor can be formed into contact surfaces of various shapes as shown in the twentieth diagram.

Similar to the nineteenth D picture, the compressible insulating material 1979 and the position of the conductor are also Can be interchanged. The compressible insulating material 1979 can be attached to the conductor base 1975, and the conductor can be attached to the rear end of the movable element 1970. When the movable element 1970 moves toward the rear end, the conductor causes the compressible insulating material 1979 to deform, causing a change in the capacitance value of the force sensing capacitor.

Please refer to the twenty-first figure, which is a pressure according to an embodiment of the present invention. A schematic diagram of the sensor. As shown, the pressure sensor 2110 has two input terminals a, b and an output terminal c. The two input terminals a, b and the output terminal c are electrically connected to a control unit 2120. The control unit 2120 inputs the first frequency (group) F1 and the second frequency (group) F2 to the pressure sensor 2110 via the input terminals a and b, respectively, and receives the pressure sensor through the output terminal c. 2110 output signal. The control unit 2120 can implement the method illustrated in the sixth figure.

When the external pressure drives the capacitor C1 to produce a change in the capacitance value, it can also be controlled by the control The element 2120 resolves the pressure change corresponding to the change in the capacitance value, whereby the pressure sensor 2110 of the present embodiment can be widely applied to various pressure measuring devices, such as a load sensor. In an application, the pressure sensor 2110 can also be used in another type of stylus. After the received pressure change of the stylus tip is resolved by the control unit 2120, the signal transmission of a predetermined frequency f0 is driven via the control unit 2120. Unit that transmits pressure changes to the touch panel.

The premise that the sender 110 can receive the lighthouse sent by the touch panel 120 The electrical signal is sent for a period of time after the signal, so that the touch processing device 130 can detect the state of the transmitter 110 and its sensor. When the bearer signal is not received for the first time, the transmitter 110 may enter the power saving mode, and detect whether there is a beacon signal after a detection period, until the beacon signal is received, and then continuously detect The beacon signal, wherein the detection period is greater than the transmission period of the beacon signal.

In addition, when the above-mentioned beacon signal is not received for a second period of time, The messenger 110 can be in a sleep mode, turning off most of the power of the circuitry or controller of the transmitter 110 until it is woken up. In an embodiment of the invention, in the sleep mode, the transmitter 110 turns off the associated circuitry that receives the beacon signal and transmits the electrical signal. In the wake-up of the sleep mode described above, a button or a switch may be set in the transmitter 110, and the user manually triggers a button or a switch to wake up. In another embodiment of the present invention, the embodiment of the twenty-third A and B diagrams, or the embodiment of the twenty-fourth A and B diagrams may be used to wake up. After the nib segment 230 contacts the object, the potential of the first port can be increased from low to high, thereby allowing the transmitter 110 to transmit an electrical signal.

In the present application, one of the functions of the ring electrode 550 is added for reception. The beacon signal described above is not limited to receiving the beacon signal only through the nib segment 230. Since the area and volume of the ring-shaped electrode 550 is larger than the tip end of the pen tip segment 230, the beacon signal can be received farther from the touch panel 120. Alternatively, the touch panel 120 is configured to transmit a beacon signal having a weak signal strength for reducing power consumption of the touch panel 120. If the beacon signal is not received for a period of time, the active pen can enter a deeper level of sleep to save more power consumption. In a deeper sleep state, the user can return the sender 110 to a normal operating state by tapping the tip segment 230. The transmitter 110 can be woken up using the embodiments of Figures 23A and B, or the embodiments of the twenty-fourth A and B diagrams. After the nib segment 230 contacts the object, the first The potential of the connection port is changed from low to high, thereby causing the transmitter 110 to transmit an electrical signal.

When the plurality of transmitters 110 are to be operated on one touch panel 120, The control panel 120 can emit different beacon signals to cause the corresponding transmitter 110 to emit an active signal for a period of time after receiving the beacon signal. The above-mentioned transmitter 110 can also adjust the frequency or modulation mode of the first signal source 211, the second signal source 212, and the third signal source 513 according to different beacon signals, so that the touch processing device 130 can detect It is detected which signal of the transmitter 110 is. Similarly, the different beacon signals described above may be of different frequencies or modulations.

Please refer to the twenty-second figure, which is a pressure according to an embodiment of the present invention. A schematic diagram of the sensor.

The control unit 2220 can implement the method illustrated in the eighth figure. In an application, the drive signal of the predetermined frequency may also be input to an input c of the pressure sensor 2220 by the outside world.

Please refer to Figure 23B. After receiving the pressure, the mechanical bevel will go to the left. Pushing will deform the contact end of the upper circuit board and the lower circuit board. After the deformation, the circuit of the upper circuit board and the intermediate circuit board is open (the first contact p1 has no electrical contact with the second contact p2), or the circuit of the intermediate circuit board and the lower circuit board is open (the third contact) P3 has no electrical contact with the fourth contact p4), and the potential of the first port GPIO1 is the potential of the voltage source Vdd.

When the potential of the first port 埠 GPIO1 turns from low to high, it can be in sleep mode. The sender 110 is woken up. As mentioned earlier, the upper circuit board and the lower circuit board may be provided with supporting members so that after the power of the mechanical bevel disappears, the upper circuit board and the lower circuit board are restored to the original state, and the potential of the first connection port is turned high. low. The aforementioned first port and second port may be pins of a processor within the transmitter 110.

The embodiment of the twenty-fourth A and B diagrams has only one break and the circuit is connected from the intermediate circuit board to the ground potential. When the circuit of the upper circuit board and the intermediate circuit board is short-circuited, the potential of the first connection 埠 GPIO1 is a low potential or a ground potential. When the circuits of the upper circuit board and the intermediate circuit board are open, the potential of the first connection 埠 GPIO1 is the potential of the voltage source. In the twenty-fourth A and B pictures, the first The two contacts p2 are electrically connected to the second port GPIO2.

Referring to the twenty-fifth figure, the present invention provides an indication of inferring the position of the nib Figure. There are two transmitters 110 on the drawing, both of which include a ring electrode 550 and a tip segment 230. The transmitter 110 on the left and the touch panel 120 are in a vertical state with an angle close to or equal to 90 degrees, and the angle between the right transmitter 110 and the touch panel 120 is less than 90 degrees. The surface transparent layer of the touch panel 120 has a thickness. Generally, the surface transparent layer is typically a tempered glass and the display layer is positioned below the transparent layer.

Since the transmitter 110 is emitted from the ring electrode 550 and/or the pen tip segment 230 during the R period The touch signal processing device 130 can calculate the center of gravity position R_cg of the signal, corresponding to the annular electrode 550 and the tip portion 230 projected on the center of the touch panel 120. Next, during the T0 and T1 periods, the transmitter 110 transmits an electrical signal only through the tip segment 230. The touch processing device 130 can calculate the center of gravity position Tip_cg of the signal, corresponding to the pen tip segment 230 projected on the center position of the touch panel 120.

The transmitter 110 on the left side of the twenty-fifth figure, when it is perpendicular to the touch panel 120 When R_cg is equal to or very close to Tip_cg. Therefore, it can be inferred that the tip of the pen touches the surface transparent layer of the touch panel 120, and the Tip_surface is equal to the above-mentioned R_cg and Tip_cg. It can also be inferred that the tip of the pen is projected on the display layer of the touch panel 120, and the Tip_display is equal to the R_cg, Tip_cg, and Tip_surface described above.

The transmitter 110 on the right side of the twenty-fifth figure is sandwiched with the touch panel 120. The inclination angle, so R_cg is not equal to Tip_cg. It is conceivable that the further the distance between the two, the greater the inclination. According to different transmitter 110 designs, the touch processing device 130 can look up or calculate the tilt angle according to the two center of gravity positions R_cg and Tip_cg, or calculate that the tip end of the tip portion 230 contacts the surface of the touch panel 120. The transparent layer and the display layer point Tip_surface Tip_display.

Please refer to the twenty-sixth figure, which is a calculation according to an embodiment of the present invention. Schematic diagram of the tilt angle. This embodiment is applicable to the transmitter 110 shown in the fifth figure, which has an annular electrode 550. The embodiment is applicable to the signal modulation mode shown in the ninth E and the ninth F. The touch processing device 130 shown in the first embodiment performs the method shown in this embodiment, and may also refer to the twenty-fifth. An embodiment of the figure.

In step 2610, the ring electrode 550 and/or the nib segment 230 are calculated on the touch surface. A first central position R_cg on the plate 120. In step 2620, a second center position Tip_cg of the nib segment 230 on the touch panel 120 is calculated. The present invention does not limit the order in which the two steps 2610 and 2620 are performed. Next, in an optional step 2630, a tilt angle is calculated based on the first center position R_cg and the second center position Tip_cg. In an optional step 2640, the surface position Tip_surface of the nib segment 230 on the surface layer of the touch panel 120 is calculated according to the first central position R_cg and the second central position Tip_cg. In an optional step 2650, the display position Tip_display of the pen tip segment 230 on the display layer of the touch panel 120 is calculated according to the first central position R_cg and the second central position Tip_cg. The invention is not limited to having to perform steps 2630 through 2650, but at least one of them needs to be performed. The present invention also does not limit the order in which steps 2630 through 2650 are performed.

Please refer to the twenty-seventh figure, which shows the interface response to the aforementioned tilt angle and / Or an embodiment of a stroke of pressure. The twenty-seventh diagram contains five sets of horizontal embodiments (a) to (e), each set containing three inclinations, the leftmost straight row indicating that the active pen has no tilt angle, and the right example The second tilt angle is greater than the first tilt angle of the intermediate example, and the direction of the tilt angle is toward the right. The so-called strokes here are usually displayed in the drawing software and displayed in the color range of the screen.

It is worth noting that in this embodiment, it is not necessary to use the twenty-fifth figure and the The ring-shaped electrode of the twenty-sixth figure is used to calculate the inclination angle and the tip of the tip portion 230 contacting the surface transparent layer and the display layer of the touch panel 120, Tip_surface and Tip_display. In an embodiment, other sensors may be mounted on the pen to measure the tilt angle. For example, an inertial measurement unit (IMU), a gyroscope, an accelerometer, etc., which are made of MEMS, measure the tilt angle and transmit it through various wired or wireless transmission methods. The various data derived from the tilt angle and/or the tilt angle are transmitted to the computer system to which the touch panel belongs, so that the computer system implements the various embodiments shown in FIG. The above wired or wireless transmission methods may be industry standards or custom standards, such as Bluetooth wireless communication protocol or Wireless USB.

It is assumed here that in the twenty-seventh diagram, the active pens of the respective embodiments all use the same pressure. Touch the touch panel. In an embodiment, the intersection of each horizontal line and the straight line represents a point Tip_surface at which the pen tip segment actually contacts the surface transparent layer of the touch panel. In other embodiments, the intersection of each horizontal line and the straight line represents the center of gravity position Tip_cg of the nib signal. Of course, in other embodiments, the point Tip_display of the pen tip projected on the display layer of the touch panel may also be indicated. For convenience, it may be collectively referred to as a nib representative point Tip, which may be the above-mentioned Tip_display, Tip_surface or Tip_cg.

In the embodiment (a), when the tilt angle is increased, the shape of the stroke will be from a circle It becomes oval. In other words, the distance between the elliptical bifocal points is related to the tilt angle. The larger the angle of inclination, the greater the distance between the elliptical bifocal points. The center point of the ellipse is the above-mentioned nib representative point Tip.

The difference between the embodiment (b) and the embodiment (a) is that in the elliptical bifocal The intersection of the heart extension line and the elliptical line is the tip point of the above-mentioned nib. Example (c) and implementation The difference of the example (a) is that one of the focal points of the elliptical bifocal point is the above-mentioned nib representative point Tip. The embodiments (d) and (e) differ from the embodiment (a) in that the shape of the stroke is changed from an elliptical shape to a teardrop type. The teardrop tip of the embodiment (d) is the tip point Tip described above. The teardrop type tip of the embodiment (e) is directed to somewhere at the end, which is the above-mentioned nib representative point Tip.

Although in the twenty-seventh figure, the two shapes are different from the ones indicated. Point, but the application does not limit the shape of the stroke and the type of point it represents. In addition, in one embodiment, the pressure of the nib can control the size of the shape described above, such as the magnitude of the pressure associated with the radius of the circle or the distance from the bifocal point of the ellipse. In summary, the human-machine interface can change the displayed content according to the pen tip pressure value and/or the tilt angle of the active pen.

In addition to changing the shape of the stroke, the above-mentioned tip pressure value and/or inclination angle Values can also represent different commands. For example, in the 3D design software, the color temperature of the light source, or the intensity of the light source, or the illumination range of the light source can be adjusted by the tilt angle. Or, after the nib selects an object, the direction of the object can be adjusted by the direction of the tilt angle, and the rotation direction of the object can be adjusted according to the angle of the tilt angle.

It should be noted that the present invention does not limit the relationship between the tilt angle and its associated value. Linear. In some embodiments, the relationship of the tilt angle to its associated value may be non-linear, may be looked up using a look-up table, or may be a quadratic function.

Please refer to the twenty-eighth figure, which is to reflect the aforementioned inclination angle and / on the display interface. Or another embodiment of a stroke of pressure. The twenty-eighth figure contains two embodiments (a) and (b), each of which contains two left and right strokes. The left hand stroke has a tilt angle of zero and contains five small to large circles C1 to C5, the size of which depends on the pressure value of the pen tip. The stroke on the right has a fixed angle of inclination, containing five small to large ovals E1 to E5, which are elliptical The size is also based on the pressure value of the pen tip and is the same as the pressure value of C1 to C5. In addition, according to the direction of the inclination angle, the axial directions of the elliptical shapes E1 to E5 are inclined by 30 degrees, and the inclination direction of the inclination angle is different from the stroke direction of the stroke center. . In this picture, the two are clipped at a 15 degree angle.

The (a) embodiment of the twenty-eighth figure corresponds to the (a) embodiment of the twenty-seventh figure, That is, the center point of the ellipse corresponds to the above-described nib representative point Tip. Similarly, the embodiment (b) of the twenty-eighth diagram corresponds to the embodiment (b) of the twenty-seventh diagram, and the intersection point of the center extension line of the elliptical bifocal point and the elliptical line is the above-mentioned nib representative point. Tip. It can be seen from the two embodiments of the twenty-eighth figure that under the same pressure change, due to the difference in the inclination angle, the overall shape of the brush stroke is different. Thereby, the pressure value and the tilt angle can be used to express the strokes of some soft elastic tip, such as a brush pen or a quill pen.

In an embodiment of the invention, the first electrode 121 included in the touch panel 120 The parallel spacing between the second electrode 122 and the second electrode 122 is greater than the tip of the nib segment 230. As shown in the twenty-fifth figure, when the nib of the nib section 230 is inclined, it may have a large contact area with the touch panel 120. However, in a typical example, the diameter of the nib contact area is up to about 1 mm, and the spacing between two adjacent first electrodes 121 or second electrodes 122 may be as wide as 4 mm to 5 mm. In other words, the probability that the nib segment 230 is above the first electrode 121 or the second electrode 122 will be much less than the probability that the nib segment 230 is between the first electrode 121 or the second electrode 122.

Please refer to the thirty-fifth figure, which is a transmitter according to an embodiment of the present invention. Schematic diagram of signal strength. In part (a) of the figure, a part of the touch panel 120 includes two adjacent first electrodes 121a and 121b. When the touch processing device 130 detects a proportional value of the electrical signal strength of the transmitter 110, so as to know the pressure of the pen tip segment 230, it will separately detect The electrical signals sensed by all of the first electrodes 121 are measured. When the movement trajectory of the nib segment 230 on the touch panel 120 is 3510, and it is assumed that it emits an electrical signal of the same intensity, the corresponding electrical signal strength obtained by the touch processing device 130 may be as shown in part (b). The chord line segment 3520.

As shown in part (b) of the thirty-fifth figure, when the nib segment 230 is near or at the first When the electrode 121a or 121b is above, the total intensity of the received electrical signal is the largest. When the nib segment 230 is located between the two adjacent first electrodes 121a and 121b, the total intensity of the received electrical signal is minimal. In other words, when located above the electrode, the signal-to-noise ratio of the electrical signal strength and the noise signal strength emitted by the transmitter 110 is the highest; conversely, when located in the middle of the adjacent electrode, the electrical signal strength and the noise emitted by the transmitter 110 are different. The signal strength has the lowest signal to noise ratio. Since the present invention can utilize the proportional value of one of the two sets of frequencies in the electrical signal to estimate the sensed value of a sensor, such as the pressure value experienced by the nib segment 230. Although at any point of the signal strength 3520, the ratio is theoretically the same, if the sample with low signal-to-noise ratio is taken, the estimated ratio may be affected by noise and increase the degree of error. Therefore, one of the features of the present invention is to select a sample with a high signal strength or to select a sample with a high signal-to-noise ratio, and then calculate a proportional value of the different frequency signals contained therein. Thus, the sensed value of a certain sensor is derived.

Please refer to the thirty-sixth figure, which is a touch surface according to an embodiment of the invention. Schematic diagram of the partition of the board 120. The touch processing device 130 is connected to the plurality of first electrodes 121 and the plurality of second electrodes 122 of the touch panel 120 . In one embodiment, the touch processing device 130 can detect the electrical signals of the plurality of first electrodes 121 in a time-sharing manner or simultaneously, and can also detect the electrical signals of the plurality of second electrodes 122 in a time-sharing manner or simultaneously.

In an embodiment, the touch processing device 130 can simultaneously apply a plurality of first powers. The pole 121 and the plurality of second electrodes 122 detect. In this embodiment, when the pen tip segment of the transmitter 110 When the region 230 is located at a region 3610, 3630, 3670, or 3690 near the intersection of the two first electrodes 121 and the second electrode 122, the signal intensity detected by the first electrode 121 is approximately detected by the second electrode 122. The measured signal strength is equivalent. For example, when the nib segment 230 is in the region 3670, the signal strength detected by the first electrode 121a and the second electrode 122b is substantially the same. Similarly, when the nib segment 230 is located in the region 3650, the signal intensity detected by the first electrode 121 is approximately equal to the signal strength detected by the second electrode 122.

In this embodiment, when the nib segment 230 falls in the regions 3620 and 3680, The signal intensity detected by one electrode 121 is greater than the signal intensity detected by the second electrode 122. Similarly, when the nib segment 230 falls in the regions 3640 and 3660, the signal intensity detected by the second electrode 122 is greater than the signal intensity detected by the first electrode 121.

In an embodiment, the touch processing device 130 can respectively apply a plurality of first electric The pole 121 and the plurality of second electrodes 122 detect. For example, the plurality of first electrodes 121 are detected first, and the plurality of second electrodes 122 are grounded at this time. On the contrary, when detecting the plurality of second electrodes 122, the plurality of first electrodes are grounded. In this embodiment, when the pen tip segment 230 of the transmitter 110 is located in the regions 3610, 3630, 3670, and 3690 near the intersection of the two first electrodes 121 and the second electrode 122, the first electrode 121a is detected. The resulting signal is approximately equivalent to the signal strength detected by the second electrode 122. For example, when the nib segment 230 is in the region 3670, the signal strength detected by the first electrode 121a and the second electrode 122b is substantially the same. Similarly, when the nib segment 230 is located in the region 3650, the signal intensity detected by the first electrode 121 is approximately equal to the signal strength detected by the second electrode 122.

In this embodiment, when the nib segment 230 falls in the regions 3620 and 3680, The signal intensity detected by one electrode 121 is greater than the signal intensity detected by the second electrode 122. degree. Similarly, when the nib segment 230 falls in the regions 3640 and 3660, the signal intensity detected by the second electrode 122 is greater than the signal intensity detected by the first electrode 121. In addition, half of the electrodes are grounded due to detection. Therefore, in an example, if the first electrode 121a or 121b is responsible for detecting, the signal intensity of the pen tip segment 230 in the region 3650 may be higher than the signal intensity of the pen tip segment 230 at the region 3620 or 3680, because the pen tip segment 230 is emitted. The portion of the electrical signal is grounded with the second electrode 122a or 122b. Similarly, in another example, if the second electrode 122a or 122b is responsible for detecting, the signal strength of the nib segment 230 at the region 3650 may be higher than the signal strength of the nib segment 230 at the region 3640 or 3660, because the nib segment A portion of the electrical signal emitted by 230 is grounded with the first electrode 121a or 121b.

In the above embodiment, it is necessary to first determine which block the pen tip segment 230 is located in. The domain, thereby selecting the corresponding first electrode 121 or second electrode 122. In an embodiment, when it is determined that the nib segment 230 is located in a first type of region where the first electrode 121 and the second electrode 122 meet, such as the regions 3610, 3630, 3670, and 3690, the corresponding first electrode 121 or second is selected. The electrical signal of electrode 122 is subjected to further analytical calculations. When it is determined that the nib segment 230 is located in a second type of region between the intersection of the first electrode 121 and the second electrode 122, such as the region 3650, one of the corresponding four first electrodes 121 and the second electrode 122 is similarly selected. The electrical signal is further analyzed and calculated. For example, one of the first electrode 121a, the first electrode 121b, the second electrode 122a, or the second electrode 122b is selected for further analytical calculation. When it is determined that the nib segment 230 is located near the first electrode 121 or the second electrode 122 and is not in the third type region near the intersection of the first electrode 121 and the second electrode 122, the corresponding first electrode 121 or second electrode 122 is selected. The electrical signal is further analyzed and calculated. For example, when it is determined that the nib segment 230 falls in the region 3630, the electrical signal of the second electrode 122a is selected for further analytical calculation. When it is determined that the nib segment 230 falls in the region 3680, the electrical signal of the second electrode 122b is selected as one. Analytical calculation of steps. When it is determined that the nib segment 230 falls within the region 3640, the electrical signal of the first electrode 121a is selected for further analytical calculation. When it is determined that the nib segment 230 falls in the region 3660, the electrical signal of the first electrode 121b is selected for further analytical calculation.
