Because needs initiatively send electric signal, so sender unit 110 or active pointers need electric power supply to send energy needed for electric signal.In one embodiment, the energy source of sender unit 110 can be battery, particularly rechargeable battery.In another embodiment, the energy source of lip pencil thing can be electric capacity, particularly a kind of super capacitor (Ultra-capacitor or Super-capacitor), be such as Electric double-layer capacitor (EDLC, Electrica l DoubleLayered Capacitor), simulated capacitance (Pseudocapacitor), with the super capacitor mixing electric capacity (hybrid capacitor) three kinds of kenels.The duration of charging of super capacitor is approximately with the order of magnitude calculated second, and in embodiments of the present invention, the discharge time of super capacitor is approximately with a hour order of magnitude for calculating.In other words, only need the charging of short time, just can use initiatively pen for a long time.
In one embodiment, contact panel 120 periodically can send beacon signals (beacon signal).After sender unit 110 or pointer nib closely receive contact panel 120, sender unit 110 can sense this beacon signals by nib, and then starts to send electric signal and reach a period of time, for the use of contact panel 120 detecting.Thus, sender unit 110 or can when not detecting this beacon signals, stopped sending this electric signal, by the service time extending sender unit 110 power supply.
Above-mentioned beacon signals can utilize many first electrodes 121 and/or the second electrode 122 to send.In one embodiment, when utilizing the first electrode 121 to send the drive singal of mutual capacitance touch detection, this drive singal is different from the frequency of this beacon signals, and is not the resonance wave of the other side.Therefore, this beacon signals can be sent during sending drive singal simultaneously, that is carry out the detecting of mutual capacitance touch detection and electric signal simultaneously.In another embodiment, can send this drive singal and beacon signals in turn, that is the detecting of mutual capacitance touch detection and electric signal is carried out in timesharing, the frequency of this drive singal and this beacon signals can be identical or different.
In one embodiment, remotely also beacon signals can be detected at distance contact panel 120 for making sender unit 110, the first electrodes 121 all on touch-control treating apparatus 130 pairs of contact panels 120 and the second electrode 122 can be made to send drive singal at one time, and the signal intensity summation sent to make contact panel 120 is maximum.
Please refer to shown in Fig. 2 A, it is the schematic diagram of sender unit 110 inside according to an embodiment of the invention.This sender unit 110 comprises the first signal source 211, secondary signal source 212, first element 221 with the first impedance Z 1, second element 222 with the second impedance Z 2 and nib section 230.Wherein, the first signal that this first signal source 211 sends, after this first element 221 and nib section 230, is sent to contact panel 120.Similarly, the secondary signal that this secondary signal source 212 sends, after this second element 222 and nib section 230, is sent to contact panel 120.
In one embodiment, this first signal is the signal comprising first frequency f1, and this secondary signal is the signal comprising second frequency f2.This first frequency f1 and second frequency f2 can be square-wave signal, also can be string ripple signal, also can be the signal after pulse width modulation (Pulse Width Modulation).In one embodiment, this first frequency f1 is different from the frequency of this beacon signals and the frequency of this drive singal, is also different from the resonance frequency of the frequency of this beacon signals and the frequency of this drive singal.This second frequency f2 is different from this first frequency f1, the frequency of this beacon signals and the frequency of this drive singal, be also different from this first frequency f1, this beacon frequency signal with the resonance frequency of the signal of this driving frequency.
The signal of these two frequencies is separately through having the first element 221 of the first impedance Z 1 and having the second element 222 mixing afterwards of the second impedance Z 2, and feed-in nib section 230.The first above-mentioned element 221 and the second element 222 can be resistive elements, inductance element, capacity cell (as solid capacitor) or its combination in any the impedance that causes.In the embodiment shown in Fig. 2 A, the second impedance Z 2 can be changeless, and the first impedance Z 1 is variable, and corresponding to the variable quantity of a certain sensor.
In another embodiment, the first impedance Z 1 and the second impedance Z 2 are all variable, and the ratio value both it is corresponding to the variable quantity of a certain sensor.In one embodiment, this sensor can be telescopic elastic pen point, and the first above-mentioned impedance Z 1 can change corresponding to the stroke of elastic pen point or stressed degree.In some example, the first above-mentioned impedance Z 1 is linearly corresponding to the change of the physical quantity of sensor.But in other example, the first above-mentioned impedance Z 1 is non-linearly corresponding to the change of the physical quantity of sensor.
The first above-mentioned element 221 can be different electronic components from the second element 222.Such as the first element 221 is resistance, and the second element 222 is electric capacity, and vice versa.Such as the first element 221 is resistance again, and the second element 222 is inductance, and vice versa.Such as the first element 221 is inductance again, and the second element 222 is electric capacity, and vice versa.In above-mentioned first impedance Z 1 and the second impedance Z 2, at least one is variable, the electric capacity that such as resistance variable resistor, capacitance are variable or the variable inductance of inductance value.When the one in above-mentioned first impedance Z 1 and the second impedance Z 2 is immutable, can arrange with existing electronic component, the resistive element of such as general fixed resistance value, the fixing capacity cell of capacitance or the inductance element of fixed inductance value.
In one embodiment, the first element 221 can be power sensing resistor (FSR, force sensing resistor), the corresponding suffered acting force of its resistance value and produce expected change, and the second element 222 can be fixed resistance.In another embodiment, the first element 221 can be variable resistor.Therefore, when other conditions are identical, in the middle of the electric signal that pen tip 230 sends, the ratio of the intensity M2 of the intensity M1 of the signal section of first frequency f1 and the signal section of second frequency f2, is inversely proportional to the ratio with the first impedance Z 1 and the second impedance Z 2.That is M1/M2=k (Z2/Z1) in other words.About the circuit analysis of this part, refer to the follow-up explanation about Fig. 2 D and Fig. 2 E part.
Therefore, when sender unit 110 is suspended in the top of contact panel 120, nib section 230 not yet has any displacement or stressed, so in the middle of the electric signal that detects of contact panel 120, the ratio of the intensity M2 of the intensity M1 of the signal section of first frequency f1 and the signal section of second frequency f2 is a fixed value or preset value.Or in another embodiment, the ratio of (M1-M2)/(M1+M2) or (M2-M1)/(M1+M2) is also a fixed value or preset value.In addition, the ratio of M1/ (M1+M2) or M2/ (M1+M2) also can be utilized to represent force value.Beyond above-mentioned four kinds of ratios, the those of ordinary skill being familiar with this skill also can be expected replacing with any ratio value involving intensity M1 and M2.In other words, when detecting this ratio value for this fixed value, then can judge that this sensor does not sense this physical quantity and has any variable quantity.In one embodiment, namely sender unit 110 does not touch contact panel 120.
After sender unit 110 touches contact panel 120, namely nib section 230 has displacement stroke because of stressed.Namely first impedance Z 1 of this first element 221 changes corresponding to the stroke of nib section 230 or stressed degree, and the ratio of the intensity M2 of the signal section of the intensity M1 of the signal section of first frequency f1 in the middle of electric signal and second frequency f2 is changed, be different from above-mentioned fixed value or preset value.Contact panel 120 in order to by above-mentioned relation, can produce corresponding sensing value according to this ratio.Aforesaid fixed value or preset value are not limited to single numerical value, can also be the scopes in error tolerance.
It should be noted that this ratio and this sensing value may not have linear relation.Further, the displacement stroke of this sensing value and this sensor or the stressed degree of this sensor also may not have linear relation.This sensing value is the value that this contact panel 120 senses, and the present invention does not limit its relation.For example, this contact panel 120 can utilize look-up table or multiple computing formula to correspond to this sensing value from this ratio.
Please refer to shown in Fig. 2 B, it is the schematic diagram of sender unit 110 inside according to an embodiment of the invention.Similar with the embodiment of Fig. 2 A, the embodiment shown in Fig. 2 B, after the mixed signal that the first element 221 and the second element 222 export, adds an amplifier 240, for amplifying this mixed signal more.In one embodiment, for above-mentioned first frequency f1 and second frequency f2, the magnification of this amplifier 240 or gain are all identical.In one embodiment, above-mentioned amplifier 240 magnification or gain is fixing.In another embodiment, magnification or the gain of above-mentioned amplifier 240 are adjustable, and in other words, this amplifier 240 is a kind of variable gain amplifiers.
Please refer to shown in Fig. 2 C, it is the schematic diagram of sender unit 110 inside according to an embodiment of the invention.Similar with the embodiment of Fig. 2 A, embodiment shown in Fig. 2 C is after the output signal in the first signal source 211 and secondary signal source 212, connect one first amplifier 241 and one second amplifier 242 respectively, be respectively used to the output signal in amplification first signal source 211 and secondary signal source 212.In one embodiment, the magnification of above-mentioned first amplifier 241 and the second amplifier 242 or gain is fixing, and both gains are identical.In another embodiment, the magnification of above-mentioned first amplifier 241 and the second amplifier 242 or gain is adjustable, and both gains are identical.In other words, this first amplifier 241 and the second amplifier 242 are variable gain amplifiers.
Suppose in the middle of the embodiment of Fig. 2 B and Fig. 2 C, when gain and other conditions are all identical, the embodiment shown in Fig. 2 B can carry out to obtain power saving compared with the embodiment shown in Fig. 2 C.Because the signal through the first element 221 or the second element 222 is not yet exaggerated, therefore save the energy that this part consumes.In the middle of the application, before amplifier can being seated in nib section 230, to mix and to amplify the signal from the first element 221 and the second element 222, then output to nib section 230.In addition, after also amplifier can being seated in signal source, to provide larger input signal to the first element 221 and the second element 222.Those having ordinary skill in the art will appreciate that, the application is the limiting amplifier position of putting not, or whether has amplifier.Therefore in the middle of embodiment backward, no matter all omit amplifier.
Please refer to shown in Fig. 2 D and Fig. 2 E, it is two circuit analysis schematic diagram of Fig. 2 A embodiment.In the middle of this embodiment, when the electrode on the signal that nib section 230 sends and contact panel 120 forms capacitively coupled circuit, assuming that this nib section 230 is Z3 with the resulting impedance of contact panel 120.And above-mentioned first frequency signal intensity M1 and second frequency signal intensity M2 can correspond to and flows through the current value that resistance value is the circuit of Z3.Because nib section 230 and the distance of contact panel 120 are unknown, even if nib section 230 has touched contact panel 120, but the distance between nib section 230 and each electrode is also unknown, therefore resistance value Z3 is variable, along with the relative position between nib section 230 and contact panel 120 constantly changes.
In order to analyze corresponding to the current value corresponding to first frequency signal intensity M1 and second frequency signal intensity M2 respectively, Fig. 2 D and Fig. 2 E is used to be illustrated respectively.In the middle of the circuit analysis of Fig. 2 D, secondary signal source 212 does not output signal to the second element 222, the signal that first signal source 211 exports is first through the first element 221, then flow through the second element 222 in parallel and contact panel 120 more respectively, behind ground, return the first signal source 211 form loop.In the middle of the circuit analysis of Fig. 2 E, first signal source 211 does not output signal to the first element 221, and the signal that secondary signal source 212 exports is first through the second element 222, then flow through the first element 221 in parallel and contact panel 120 more respectively, behind ground, return secondary signal source 212 form loop.
In the middle of Fig. 2 D, the resulting impedance in above-mentioned loop is Z, and it can use following equation (1) to represent, wherein // represent in parallel:
Z=Z1+ (Z2//Z3) equation (1)
Equation (1) can be expressed as again equation (2):
Z = Z 1 + Z 2 Z 3 Z 2 + Z 3 Equation (2)
Suppose that the voltage that the first signal source 211 and secondary signal source 212 export is all V, flow through the electric current I 1 of the first element 221 for V/Z.The electric current I 3 flowing through contact panel 120 is the shunting of electric current I 1, can be expressed as equation (3):
I 3 = V Z · Z 2 Z 2 + Z 3 Equation (3)
Similarly, in the middle of Fig. 2 E, the resulting impedance in above-mentioned loop is Z ', and it can use following equation (4) to represent, wherein // represent in parallel:
Z '=Z2+ (Z1//Z3) equation (4)
Equation (4) can be expressed as again equation (5):
Z , = Z 2 + Z 1 Z 3 Z 1 + Z 3 Equation (5)
The voltage exported due to secondary signal source is equally also V, and the electric current I 2 flowing through the second element 222 is V/Z '.The electric current I 3 ' flowing through contact panel 120 is then the shunting of electric current I 2, can be expressed as equation (6):
I 3 , = V Z , · Z 1 Z 1 + Z 3 Equation (6)
Equation (3) and equation (6) are divided by, equation (7) can be obtained:
I3/I3 '=Z2/Z1 equation (7)
Because M1 and M2 is respectively corresponding to I3 and I3 ', so the ratio of the intensity M2 of the signal section of the intensity M1 of the signal section of first frequency f1 and second frequency f2, the ratio with the first impedance Z 1 and the second impedance Z 2 is inversely proportional to.That is M1/M2=k (Z2/Z1) in other words.From equation (3) and equation (6), current value I3 and I3 ' has common common divisor CD.If arbitrary ratio value of I3 and I3 ' can be learnt, and the second known impedance Z 2, just can push back the first variable impedance Z 1.In other words, equation (7) need not be limited to.
If only use first element 221 of single variableimpedance Z1, in the middle of whole string loop, the 3rd impedance Z 3 between nib section 230 to contact panel 120 is also unknown.In the middle of same equation, have two unknown parameters, be the value that cannot calculate variableimpedance Z1.If touch-control treating apparatus 130 assumes the value of the 3rd impedance Z 3 actually, then the error range of the value of calculated variableimpedance Z1 just becomes larger.

This detecting module 2920 comprises AFE (analog front end) 2921 and comparer 2922.Those having ordinary skill in the art will appreciate that and the thing that AFE (analog front end) 2921 is done do not add detailed description at this.In the present embodiment, this AFE (analog front end) 2921 can comprise the magnitude of voltage exporting and represent this signal intensity.This comparer 2922 is for comparison reference voltage Vref and the voltage signal representing received signal strength.When this voltage signal is higher than this reference voltage, represents and receive enough strong signal, therefore comparer 2922 exports activation signal or enable signal to this demodulator 2930.This demodulator 2930 just can carry out solution modulation for Received signal strength, to learn the frequency whether comprising beacon signals in the middle of Received signal strength.When this voltage signal is lower than this reference voltage, then comparer 2922 can export shutdown signal to this demodulator 2930, and this demodulator 2930 carries out solution modulation with regard to stopping to this Received signal strength.
When this sender unit 110 does not receive beacon signals in a period of time, can sleep pattern be switched to, close above-mentioned demodulator 2930, to save power consumption.But the electric power consumed due to detecting module 2920 is less, can continues to detect the signal intensity received in a sleep mode and whether exceed predetermined value.When a predetermined value is exceeded, the energy saver mode of more not power saving can be converted to from sleep pattern, activate this demodulator 2930 and carry out solution modulation.At the same time, the remainder of this sender unit 110 is still in closed condition.Suppose that this demodulator 2930 thinks that received signal does not comprise beacon signals, then through after a period of time, this demodulator 2930 can be closed, enter the sleep pattern compared with power saving by energy saver mode.Otherwise when this demodulator 2930 thinks that received signal comprises beacon signals, then this demodulator 2930 can wake other parts of this sender unit 110 up, this sender unit 110 is made to convert normal mode of operation to by energy saver mode.
Get back to now the embodiment of Fig. 9 A, after the time delay through L0 length, sender unit 110 sends electric signal in T0 period and T1 period respectively.Between these two period T0 and T1, also may include the time delay of L1 length.And these two period T0 and T1 can be isometric, it also can be Length discrepancy.T0 and T1 can be collectively referred to as signal frame (frame).Touch-control treating apparatus 130 can detect the electric signal that sender unit 110 sends in the middle of these two period T0 and T1.Then, after the time delay of optional L2 length, touch-control treating apparatus 130 carries out the detecting step of other patterns optional, and such as previously mentioned condenser type sense mode, starts writing for detecting non-master or point.
The present invention does not limit the length of above-mentioned time delay L0, L1, L2, and this three can be zero, or arbitrary time span.The length of this three can have relation, also can without any relation.In the middle of embodiment, in the middle of each period shown in Fig. 9 A, only have T0 and the T1 period in the middle of signal frame to be necessary, other period or step are all optional.
Table one
Please refer to table one, it is the modulation table of the electric signal of sender unit 110 according to an embodiment of the invention.In the middle of table one, this sender unit 110 is suspended state, that is force snesor does not experience any pressure.Because the nib section 230 of sender unit 110 does not touch contact panel/screen 120, in order to strengthen for the purpose of signal, therefore, in the middle of the embodiment of table one, the first signal source 211 in the middle of the same period, all produces identical frequency group Fx with secondary signal source 212.For example, in the state that penholder button is pressed, in the T0 period, the first signal source 211 and secondary signal source 212 all transmission frequency group F0, and within the T1 period, the first signal source 211 and secondary signal source 212 all transmission frequency group F1.When touch-control treating apparatus 130 detects frequency group F0 within the T0 period, when detecting frequency group F1 within the T1 period, the penholder button just can knowing the sender unit 110 being in suspended state by inference has been pressed.
Aforesaid frequency group Fx comprises the signal of at least one frequency, can exchange each other.For example, frequency group F0 can comprise f0 and f3 frequency, and frequency group F1 can comprise f1 and f4 frequency, and frequency group F2 can comprise f2 and f5 frequency etc.No matter be receive f0 frequency or f3 frequency, touch-control treating apparatus 130 all can be considered as receiving frequency group F0.
In another embodiment, the sender unit 110 in suspended state not necessarily two signal sources 211 and 212 all send the signal of same frequency group.The present invention not qualified list one as unique embodiment.In addition, sender unit 110 also can comprise more button or sensor, and the present invention does not limit only has two buttons.
Table two
Please refer to table two, it is the modulation table of the electric signal of sender unit 110 according to an embodiment of the invention.In the middle of table two, the nib section 230 of this sender unit 110 is contact condition, that is force snesor has experienced pressure.
In the embodiment shown in Fig. 4 A, it is below the situation that penholder button SWB is pressed.In the middle of the T0 period, the signal source of the first signal source 211 is grounded, and secondary signal source 212 sends frequency group F0, therefore the electric signal of the sender unit 110 frequency group F0 that only has secondary signal source 212 to send in the middle of the T0 period.In the middle of the T1 period, the signal source in secondary signal source 212 is grounded, and the first signal source 211 sends frequency group F1.Also because the resistance value of the first electric capacity 321 changes when contacting, the intensity of F0 and the F1 signal that can receive respectively according to T0 and the T1 period calculates the stressed degree of nib section 230.In addition, because touch-control treating apparatus 130 detects F0 signal within the T0 period, within the T1 period, detect F1 signal, just can know penholder button by inference and be pressed.
In the embodiment shown in Fig. 4 B, it is below the situation that penholder button SWB is pressed.In the middle of the T0 period, the signal source of the first signal source 211 is grounded, and secondary signal source 212 sends frequency group F0, and the second electric capacity 322 is together in parallel with penholder electric capacity 442.Although the frequency group F0 that the electric signal of sender unit 110 only has secondary signal source 212 to send in the middle of the T0 period, its signal intensity is different from the situation that penholder button SWB is not pressed.In the middle of the T1 period, the signal source in secondary signal source 212 is grounded, first signal source 211 sends frequency group F1, also because the resistance value of the first electric capacity 321 changes when contacting, the intensity of F0 and the F1 signal that can receive respectively according to T0 and the T1 period calculates the stressed of pointer.In addition, because touch-control treating apparatus 130 detects F0 signal within the T0 period, within the T1 period, detect F1 signal, just can know penholder button by inference and be pressed.
Table three
Please refer to table three, it is the modulation table of the electric signal of sender unit 110 according to an embodiment of the invention.In this embodiment, can learn which button is pressed according to frequency group.
Table four
Please refer to table four, it is the modulation table of the electric signal of sender unit 110 according to an embodiment of the invention.In this embodiment, can learn that those buttons are pressed according to frequency group, also rely on the signal intensity ratio that receives of T0 and T1 period, calculate the stressed degree of touch-control nib.
Please refer to shown in Fig. 9 B, it is the time diagram of the modulating signal of sender unit 110 according to an embodiment of the invention.It is another distortion of Fig. 9 A embodiment.Be with the difference of Fig. 9 A, after the T1 period, carried out the step of noise detecting., then perform the detecting of other patterns then.
Please refer to shown in Fig. 9 C, it is the time diagram of the modulating signal of sender unit 110 according to an embodiment of the invention.The modulating signal of Fig. 9 C goes for the sender unit 110 shown in Fig. 5, adds another function of ring electrode 550, is exactly signal intensity when strengthening initiatively pen suspension, in order to the suspension scope of touch panel detection active pen.
The modulating signal of Fig. 9 C is by being sent signal when sender unit 110 is in suspended state.In this case, single R period is only comprised in the signal frame that sender unit 110 sends signal.Within this R period, ring electrode 550 and nib section 230 can send electric signal simultaneously.In one embodiment, these electric signal from same signal source, can have identical frequency and/or modulation mode.For example, ring electrode and nib all send the electric signal of the 3rd signal source 513.Again for example, ring electrode 550 and nib section 230 can jointly sequentially send first, second, with the electric signal of the 3rd signal source, to utilize the peak power of each signal source respectively.Touch-control treating apparatus 130, in the middle of the R period, only needs to detect the electric signal that ring electrode 550 sends, just can learn that sender unit 110 is just being suspended on certain position of contact panel 120.If ring electrode 550 and the electric signal that nib section 230 sends are from identical signal source, or have identical frequency group, its signal intensity can be maximum, and the suspension scope of touch panel detection pointer so can be made to reach maximum.Within the R period in the middle of another embodiment, also only can send electric signal by ring electrode 550.
Please refer to shown in Fig. 9 D, it is the time diagram of the modulating signal of sender unit 110 according to an embodiment of the invention.The modulating signal of Fig. 9 D goes for the sender unit 110 shown in Fig. 5.In the middle of Fig. 9 C, after the R period, comprise a time delay or blank interval L1, contact panel carries out other forms of detecting more afterwards.The embodiment of Fig. 9 D is compared with Fig. 9 C, and the time of L1 period is elongated.Fig. 9 D is compared with the embodiment of Fig. 9 E, and the length of L1 period equals the summation of the L1 period of Fig. 9 E, T0 period, L2 period, T1 period and T3 period.Therefore, if the touch-control treating apparatus 130 of Fig. 9 D is detected less than any electric signal within the L1 period of regular length, then can learn that sender unit 110 is in suspended state.
Please refer to shown in Fig. 9 E, it is the time diagram of the modulating signal of sender unit 110 according to an embodiment of the invention.The modulating signal of Fig. 9 E goes for the sender unit 110 shown in Fig. 5.Fig. 9 E embodiment can be described as and the signal frame front of Fig. 9 A embodiment is added the R period.In this embodiment, no matter whether nib section 230 has is touched by pressure, and sender unit 110 sends electric signal in T0 period and T1 period from nib without exception, can save the design of some logical circuits by this.But compare with the embodiment of Fig. 9 D with Fig. 9 C, the embodiment of Fig. 9 E can be wasted in the electric signal power that T0 period and T1 period send.On the other hand, touch-control treating apparatus 130 also can be detected in the R period, as long as can detect in T0 period and T1 period the electric signal that nib section 230 sends, naturally just can learn whether nib section 230 is under pressure, thus learn whether sender unit 110 is in suspended state.
Please refer to shown in Fig. 9 F, it is the time diagram of the modulating signal of sender unit 110 according to an embodiment of the invention.The modulating signal of Fig. 9 F goes for the sender unit 110 shown in Fig. 5.In the embodiment of Fig. 9 E, do not limit the proportionate relationship of length of R period and T0 period, T1 period.In the middle of the embodiment of Fig. 9 F, the R period is 1:2:4 with the length ratio of T0 period, T1 period.Thus, assuming that touch-control treating apparatus 130 can carry out N sub-sampling within the unit interval, N is positive integer.So within R period and T0 period, T1 period, contact panel can carry out N:2N:4N sub-sampling.The present invention does not limit the length ratio of these three periods, for example, can allow and send the strongest period lasts of the electric signal power minimum unit interval, allows and sends the minimum period lasts of the electric signal power the longest unit interval.Such as, length ratio can be 1:3:2, or 1:2:3 etc., end relies to be determined in design.Although in the middle of above-mentioned length, only enumerate the modulation of two periods of T0 and T1, the present invention is not limited to the modulation of two periods, and goes for the modulation of more period.
In one embodiment, sender unit 110 can send the larger electric signal of intensity when nib does not contact, and when Stylus contact time, send the less electric signal of intensity.Accordingly, touch-control treating apparatus 130 can be allowed to have larger probability to detect be suspended in sender unit 110 above contact panel 120.And after sender unit 110 touches contact panel 120, the energy that sender unit 110 consumes can be saved.
Such as, in the middle of the embodiment of Fig. 9 C and Fig. 9 D, that is when nib section 230 is not touched, the electric signal sent in the R period can be greater than the electric signal that L1 period of corresponding to T0 period and T1 period sends.For example, in the middle of the R period, the electric signal sent by nib section 230 and ring electrode 550 comes from the first signal source 211, secondary signal source 212 and the 3rd signal source 513.Therefore, the electric signal that sends is the summation that these three signal sources 211,212 and 513 export the R period.
And in the middle of embodiment as Fig. 9 A, table one be sender unit 110 when suspended state, use the output power in the first signal source 211 and secondary signal source 212.Table two be sender unit 110 when contact condition, only use the output power in the first signal source 211 or secondary signal source 212 in T0 period and T1 period.Therefore, sender unit 110 can send the larger electric signal of intensity when nib does not contact, and when Stylus contact time, send the less electric signal of intensity.
Similarly, table three be sender unit 110 when suspended state, use the output power in the first signal source 211 and secondary signal source 212.Table four be sender unit 110 when contact condition, only use the output power in the first signal source 211 or secondary signal source 212 in T0 period and T1 period.Therefore, sender unit 110 can send the larger electric signal of intensity when nib does not contact, and when Stylus contact time, send the less electric signal of intensity.
Why in the middle of the embodiment of Fig. 9 A to Fig. 9 F, will add step and the period of noise detecting, shown in Figure 10, it is noise transmission schematic diagram according to an embodiment of the invention.In the middle of Figure 10, the electronic system 100 at contact panel/screen 120 place itself can send the noise of f0 frequency, and f0 frequency is a frequency in the middle of frequency group F0 just.Assuming that frequency group F0 further comprises another f3 frequency.When user's this electronic system 100 hand-held, the noise of f0 frequency will be delivered on contact panel/screen 120 by the finger of user.If do not carry out the step of noise detecting, then contact panel/screen 120 may miss pointing the f0 frequency signal transmitted, as being the electric signal that sender unit 110 sends in the period of signal frame.Therefore, if detect the noise of f0 frequency in advance, namely the signal source of f0 frequency can be filtered out in the period of signal frame.
Suppose that sender unit 110 has the function of automatic frequency-conversion, when sender unit 110 itself detects the noise that contact panel/screen 120 have issued f0 frequency, and automatically use another f3 frequency of same frequency group F0 instead.Make in the period of signal frame, touch-control treating apparatus 130 detects the f3 frequency coming from sender unit 110 and the f0 frequency coming from finger, and then creates and obscure.Therefore, can embodiment as shown in Figure 9 B, when obscuring, after T1 period or signal frame, carry out the step of a noise detecting.Because sender unit 110 has stopped the signal sending f3 frequency, and finger and electronic system 100 still continue the noise sending f0 frequency.Touch-control treating apparatus 130 just can be known by inference, and in the signal detected within the script signal frame period, the signal with f3 frequency is only the signal really coming from sender unit 110.
In the middle of above-mentioned Fig. 2 A illustrates, be utilize the impedance of the first element 221 to change the ratio adjusting the signal intensity of multiple frequency.Please refer to shown in Figure 11, it is the structural representation of the first electric capacity 221 according to another embodiment of the present invention.The impedance of the first electric capacity 221 is utilized to change the ratio adjusting the signal intensity of multiple frequency.Traditional capacity cell is that two panels conductive metal sheet formed.Its permittivity C is directly proportional to sheet metal area with specific inductive capacity, and and distance between sheet metal be inversely proportional to.
At one of the main spirits of above-described embodiment, be to utilize physical construction to be changed into along the stroke of sender unit 110 axis direction by spring pen apical segment 230 and become the stroke in angle direction perpendicular to sender unit 110 axis direction or with sender unit 110 axle center.By the change of the trip, change its corresponding first impedance Z 1 of permittivity of the first electric capacity 221, and its corresponding second impedance Z 2 of permittivity of fixing reservation second electric capacity 222, changes the ratio of the intensity M1 of signal section of first frequency (group) and the intensity M2 of the signal section of second frequency (group) in the middle of electric signal accordingly.
In the middle of Figure 11, include non-touching three sheet metals.First sheet metal 1110 and the second sheet metal 1120 form the first electric capacity 221, second sheet metal 1120 and the 3rd sheet metal 1130 forms the second electric capacity 222.In an example, the first sheet metal 1110 is formed in be had on flexible circuit board or printed circuit board (PCB), and its surface has insullac or another layer of insulcrete.Second sheet metal 1120 and the 3rd sheet metal 1130 are formed in the two-layer of same circuit board or printed circuit board (PCB), and its surface has insullac or another layer of insulcrete.Second sheet metal 1120 is couple to the nib section 230 in front via other circuit.Nib is fixed in lifting element 1140 (incline device described as follows), part or all of the first sheet metal 1110 of the direct or indirect lifting of displacement according to nib section 230 (or flexible circuit board or printed circuit board (PCB)), or cause the part of the first sheet metal 1110 (or flexible circuit board or printed circuit board (PCB)) towards the deformation perpendicular to sender unit 110 axis direction, be referred to as the displacement perpendicular to pointer axis direction in the following description.
Supply the electric signal that the first sheet metal 1110 has first frequency (group), supply the 3rd sheet metal 1130 has the electric signal of second frequency (group).Therefore, the second sheet metal 1120 can respond to the electric signal that generation has first frequency (group) and second frequency (group), and the nib section 230 via front is sent to contact panel 120.When nib section 230 is not stressed, the first sheet metal 1110 and the circuit board belonging to it be not perpendicular to the displacement of sender unit 110 axis direction.But, after nib section 230 is stressed, due to the incline device 1140 after nib section, convert the stressed direction from being parallel to axle center to direction perpendicular to axle center, cause the circuit board generation deformation belonging to the first sheet metal 1110 and displacement, and then cause the specific inductive capacity of the first electric capacity 221 to change.So the permittivity C1 of the first electric capacity 221 and the first impedance Z 1 also change thereupon.After nib section 230 is stressed, the second sheet metal 1120 and the circuit board global displacement belonging to the 3rd sheet metal 1130, therefore the permittivity C2 of the second electric capacity 222 and impedance Z 2 still remain unchanged.
Because the circuit board at the first sheet metal 1110 place can deformation upward, the present embodiment can comprise at least one support component 1150 to provide reciprocal anchorage force, make after the stressed disappearance of nib section 230, help the circuit board at the first sheet metal 1110 place to restore to the original state.Before undeformed, the anchorage force that this support component 1150 provides can be zero.
In the example of the present embodiment, the first electric capacity 221 can be designed to identical with the permittivity of the second electric capacity 222.When permittivity is identical, the specific inductive capacity of these two electric capacity, distance and area can be identical.Certainly, the present invention do not limit two electric capacity 221 with 222 permittivity be identical, as long as two corresponding impedanoe ratios of electric capacity of this sender unit 110 known by touch-control treating apparatus 130.
In this embodiment, cheap circuit board or printed circuit board (PCB) is adopted to replace power sensing resistor costly.Further, when the first electric capacity 221 is identical with the permittivity of the second electric capacity 222, when external environment changes, its specific inductive capacity also can change simultaneously, maintains ratio preset value accordingly.In addition, sender unit 110 itself does not need active control elements to adjust two impedance Z 1 and the ratio of Z2, only needs to provide electric signal passively, can save many resources.

When deformation occurs the second sheet metal 1120, resistance value and the permittivity of the first electric capacity 221 and the second electric capacity 222 change.Therefore calculate ratio value according to these two current value I 1 with I2, according to the change of this ratio value, instead can push back deformation or the stressing conditions of the second sheet metal 1120.Accordingly, the embodiment of the method shown in Fig. 8 can be applied mechanically.
Please refer to shown in Figure 17 B, it is the one distortion of Figure 17 A illustrated embodiment.Wherein the second sheet metal 1120 and the 3rd sheet metal 1130 are fixing.The above-mentioned drive singal feed-in with a certain frequency can the first sheet metal 1110 of deformation.By the capacity effect with the first sheet metal 1110, the first responded to current value I 1 exports by the second sheet metal 1120.Similarly, by the capacity effect with the first sheet metal 1110, the second responded to current value I2 exports by the 3rd sheet metal 1130.
Formed between first sheet metal 1110 and the second sheet metal 1120 between first electric capacity 221, first sheet metal 1110 and the 3rd sheet metal 1130 and form the second electric capacity 222.When deformation does not occur the first sheet metal 1110, the resistance value of the first electric capacity 221 and the second electric capacity 222 is fixing, therefore analyzes magnitude of current I1 and I2, calculates ratio value according to these two current values.When this ratio value be preset value or fall in default scoping time, namely can know that deformation does not occur the first sheet metal 1110.
When deformation occurs the first sheet metal 1110, resistance value and the permittivity of the first electric capacity 221 and the second electric capacity 222 change.Therefore calculate ratio value according to two current value I 1 and I2, according to the change of this ratio value, instead can push back deformation or the stressing conditions of the first sheet metal 1110.Accordingly, the embodiment of the method shown in Fig. 8 can be applied mechanically.
Please refer to Figure 18, it is the schematic diagram of a kind of distortion embodiment illustrated in fig. 11.The signal needing feed-in two kinds of frequencies embodiment illustrated in fig. 11.But, in the middle of embodiment illustrated in fig. 18, as the embodiment of Figure 17 A and Figure 17 B, only need the drive singal of a certain frequency of feed-in to the second sheet metal 1120, or certain signal of feed-in, and need not know that FD feed has the composition of how many kinds of frequency.
Formed between first sheet metal 1110 and the second sheet metal 1120 between first electric capacity 221, second sheet metal 1120 and the 3rd sheet metal 1130 and form the second electric capacity 222.Because the distance of the second sheet metal 1120 and the 3rd sheet metal 1130 and specific inductive capacity can not change, therefore the capacitance of the second electric capacity 222 and impedance are fixing.When deformation does not occur the first sheet metal 1110, the resistance value of the first electric capacity 221 and the second electric capacity 222 is fixing, therefore analyzes magnitude of current I1 and I2, calculates ratio value according to these two current values.When this ratio value be preset value or fall in default scoping time, namely can know that deformation does not occur the first sheet metal 1110.But the permittivity of the first electric capacity 221 and impedance can change because of the deformation of the first sheet metal.So when the first sheet metal 1110 is because of external force during deformation, the first current value I1 can change to some extent.So the ratio value being relevant to current value I1 and I2 also can change, deformation or the stressing conditions of the first sheet metal 1110 instead can be pushed back accordingly.Accordingly, the embodiment of the method shown in Fig. 8 can be applied mechanically.
In another embodiment of the invention, controller in sender unit 110 or circuit can be that the drive singal of a certain frequency of feed-in is to the second sheet metal 1120, calculate magnitude of current I1 and the I2 corresponding to the first electric capacity 221 and the second electric capacity 222, the ratio value of both recyclings calculates sensing value, thus judges the degree that nib is stressed.In other words, by aforesaid first impedance Z 1 and the second impedance Z 2, the invention provides a kind of pressure-sensing electric capacity (FSC; Force sensitingcapacitor), can be used to replace traditional pressure sensing element, as pressure-sensing resistance FSR, provide the judgement of pressure.It is low that pressure-sensing electric capacity provided by the invention has cost, is not subject to the characteristic of temperature and humidity effect.In the middle of aforesaid each figure, disclose and utilize flexible printed circuit board (PCB) as power inductance capacitance.One of feature of the present invention, there are provided other forms of power inductance capacitance.
Please refer to Figure 19 A, it is the decomposing schematic representation of the power inductance capacitance of sender unit 110 and the centre section of its structure.Please note that the ratio of Figure 19 A to Figure 19 E changes, to highlight some part.In addition, some retaining element is omitted, so that simplified illustration.In the middle of Figure 19 A, leftmost element is long rod type nib or nib section 230, and nib can be electric conductor.For convenience's sake, title nib section 230 is the front end of sender unit 110 or active pen, and when contacting with front end moving element 1971, nib section 230 is coupled with front end moving element electrical 1971.Front end moving element 1971 is combined with the recessed fastener in the middle of rear end moving element 1972 by the convex fastener of centre.In one embodiment, convex fastener and recessed fastener can comprise screw thread.Front end moving element 1971 and rear end moving element 1972 can be conductors, or are conducting element, such as, can be metalwork.
Figure 19 A contains housing 1980, and this housing 1980 can comprise the front end and rear end moving element 1971 and 1972 living in state circlewise, and for simplicity, Figure 19 A only draws a part for this housing 1980.This housing 1980 inside contracts near the part of nib section 230 becomes the less neck of diameter, can comprise the shoulder as load part between neck and the larger part of this housing 1980 diameter.In the middle of Figure 19 A, between this load part and this front end moving element 1971, fold at least one flexible member 1978, for along the major axis of beginning to write, respectively this housing 1980 and this front end moving element 1971 have been exerted a force.This flexible member 1978 can be the flexible member of spring (spr ing), shell fragment or other types.In certain embodiment, can around the neck of moving element 1970 with this housing 1980 unlike, this flexible member 1978 with Figure 19 A.
In another embodiment, this flexible member 1978 along the major axis of beginning to write, can exert a force to this housing 1980 and this rear end moving element 1972 respectively.Because this front end and rear end moving element 1971 and 1972 can be combined into moving element 1970 by fastener, therefore no matter be that leading portion moving element 1971 or rear end moving element 1972 are exerted a force, can this moving element 1970 be pushed to nib section 230, and then nib section 230 forward end is pushed away.
When nib section 230 to be subject in figure force or to the back-end to the right, the elastic force of this flexible member 1978 can be overcome and oppress moving element 1970, until certain part contact of moving element 1970 is to the load part of this housing 1980.Therefore, design provided by the present invention, can allow moving element 1970 move along the major axis of beginning to write in the neck of this housing 1980 and reach a stroke.Similarly, because this moving element 1970 props up nib section 230, so nib section 230 also can move along the major axis of beginning to write reach same stroke.The length of the trip can change according to the difference of design, for example, can be 1mm or 0.5mm.The present invention does not limit the length of the trip.
In the rear end of rear end moving element 1972, there is one deck dielectric film 1973.In the rear end of dielectric film 1973, also comprise a compressible conductor 1974.In one embodiment, this compressible conductor 1974 can be conductive rubber or the flexible member mixing conductor.Owing to having pressed from both sides dielectric film 1973 between this moving element 1970 and this compressible conductor 1974, therefore this moving element 1970, this dielectric film 1973, just define a capacitor with this compressible conductor 1974, an or power sense capacitor.The power sense capacitor that the application provides can be first electric capacity 221 of Fig. 2 A to Fig. 5.In brief, the power sense capacitor that the application provides can be applied to each above-mentioned embodiment.
This compressible conductor 1974 is fixed in conductor substrate 1975, and this conductor substrate 1975 can be fixed on the inner peripheral surface of this housing 1980 by firmware or fastener.When moving element 1970 to the back-end or when moving right, the position due to conductor substrate 1975 is motionless, rear end moving element 1972 will compress this compressible conductor 1974, causes the capacitance of above-mentioned power sense capacitor to change.
Because the shape of pen limits, remaining circuit and battery module can be positioned at the rear end of this conductor substrate 1975.In the middle of Figure 19 A, these elements can utilize printed circuit board (PCB) 1990 representatively.As the first end of this power sense capacitor, above-mentioned moving element 1970 is connected to this printed circuit board (PCB) 1990 by moving element wire 1977.And as the second end of this power sense capacitor, above-mentioned conductor pedestal 1975 is connected to this printed circuit board (PCB) 1990 by pedestal wire 1976.
This pedestal wire 1976 also can be another flexible member.In certain embodiments, with Figure 19 A unlike, this pedestal wire 1976 can around this conductor pedestal 1975.In another embodiment, this conductor pedestal 1975 is also non-conductive, and pedestal wire 1976 is through this conductor pedestal 1975 and this compressible conductor 1974 electrical couplings.
In the middle of embodiment, the manufacture method of this dielectric film 1973 can be the right-hand member plane of this rear end moving element 1972 immersed in iknsulating liquid.After this iknsulating liquid is air-dry, nature forms a dielectric film 1973 in the right-hand member plane of rear end moving element 1972.
Please refer to shown in Figure 20, it is compressible conductor in Figure 19 A 1974 and the diagrammatic cross-section of the surface of contact of dielectric film 1973.Figure 20 contains the embodiment of the surface of contact of four kinds of compressible conductors 1974 and this dielectric film 1973.A the surface of contact of projection centered by the embodiment of (), the embodiment of (b) is the surface of contact of single ramp, the surface of contact of taper centered by the embodiment of (c), and the embodiment of (d) is the surface of contact of multiple projection.Applicant thinks that the present invention does not limit the shape of surface of contact.
Although in the middle of Figure 19 A, surface moving element 1970 being formed dielectric film 1973 is plane, and the present invention is not limited thereto.This surface can surface of contact as shown in figure 20, centered by projection, single ramp, center taper or act have the surface of contact of multiple projection.In other words, in the middle of some embodiment, compressible conductor 1974 is not plane with the surface of this both dielectric film 1973.
Please refer to shown in Figure 19 B, it is the diagrammatic cross-section after the textural association shown in Figure 19 A.After the combination, front end moving element 1971 and rear end moving element 1972 have been combined into single moving element 1970.Be connected by flexible member 1978 between this moving element 1970 and load part of this housing 1980, the elasticity tension of this flexible member 1978 makes the direction of the overall forward end of this moving element 1970 prop up nib section 230, until rear end moving element 1972 props up the load part of this housing 1980.Movable stroke d is left between moving element 1970 and housing 1980.Now, compressible conductor 1974 is not compressed and deformation, assuming that the capacitance of this power sense capacitor is the first capacitance.
Please refer to shown in Figure 19 C, its be the textural association shown in Figure 19 A after another diagrammatic cross-section.Compare with Figure 19 B, because nib section 230 is subject to pressure to the back-end, therefore move to the back-end.Affect by the movement of nib section 230, moving element 1970 overcomes the elasticity tension of flexible member 1978, moves whole section of stroke d to the back-end, until front end moving element 1971 has propped up the load part of housing 1980.Now, compressible conductor 1974 receives the compression of moving element 1970 and dielectric film 1973 and causes deformation, and the capacitance of this power sense capacitor is the second capacitance, and this second capacitance is different from the first above-mentioned capacitance.
Between the stroke end shown in Figure 19 B and Figure 19 C, moving element 1970 can also have infinite number of positions, compressible conductor 1974 can have numerous compression degree in other words conj.or perhaps, or say that compressible conductor 1974 can have numerous size variation with the area of the surface of contact of dielectric film 1973, some positions or compression degree or size change can allow the capacitance of this power inductance capacitance make change.
Please refer to shown in Figure 19 D, it is the decomposing schematic representation of the power inductance capacitance of sender unit 110 according to an embodiment of the invention and the centre section of its structure.The difference of itself and Figure 19 B is, the location swap of compressible conductor 1974 and dielectric film 1973.In any case when moving element 1970 moves to the back-end, compressible conductor 1974 will be subject to the compression of dielectric film 1973 and conductor pedestal 1975 and produce deformation.By this, the capacitance of this power inductance capacitance also can be allowed to make change.
Please refer to shown in Figure 19 E, it is the decomposing schematic representation of the power inductance capacitance of sender unit 110 according to an embodiment of the invention and the centre section of its structure.The difference of Figure 19 E and Figure 19 B is, the right-hand member of rear end moving element 1972, is no longer one deck dielectric film 1973, but one piece of compressible insulating material (compressible dielectricmaterial) 1979.Analogy is electro-insulating rubber, plastics, foam etc.And the conductor that conductor substrate 1975 connects, changing into is incompressible conductor, such as, be the material such as derby or graphite.During owing to being subject to the pressure of moving element 1970, the thickness of compressible insulating material 1979 can diminish, and causes the distance between moving element 1970 and conductor to diminish, so the capacitance of power sense capacitor can change.From being made into originally, the conductor of Figure 19 E comes expensive than the compressible conductor 1974 of Figure 19 A.
In the middle of one of Figure 19 E embodiment change, by the surface of contact of conductor and compressible insulating material 1979, the surface of contact of various shapes as shown in figure 20 can be made.In the middle of another change, by compressible insulating material 1979 and the surface of contact of conductor, the surface of contact of various shapes as shown in figure 20 can be made.
Similar with Figure 19 D, compressible insulating material 1979 also can exchange with the position of this conductor.Compressible insulating material 1979 can connect with conductor pedestal 1975, and this conductor can be connected to the rear end of this moving element 1970.When moving element 1970 moves to the back-end, this conductor can cause the deformation of compressible insulating material 1979, and the capacitance of this power inductance capacitance is changed.
