It please refers to Fig.2 shown in A, is the schematic diagram inside sender unit 110 according to an embodiment of the invention.The sender unit 110 comprising the first signal source 211, secondary signal source 212, the first element 221 with the first impedance Z 1, with the second impedance Z 2 Second element 222 and nib section 230.Wherein, the first signal which is sent, via this first yuan Part 221 is with after nib section 230, being transmitted to touch panel 120.Similarly, the secondary signal which is sent, After the second element 222 and nib section 230, touch panel 120 is transmitted to.

In one embodiment, which is the signal for including first frequency f1, which is comprising the second frequency The signal of rate f2.First frequency f1 and second frequency f2 can be square-wave signal or string ripple signal or arteries and veins Rush the signal after width modulation (Pulse Width Modulation).In one embodiment, first frequency f1 is different from The frequency of the beacon signals and the frequency of the drive signal, also different from the frequency of the beacon signals and the frequency of the drive signal Resonant frequency.Second frequency f2 is different from first frequency f1, the frequency of the beacon signals and the frequency of the drive signal, Also different from the resonant frequency of first frequency f1, the signal with the driving frequency of the beacon frequency signal.

The signal of two frequencies is each by the first element 221 with the first impedance Z 1 and with the second impedance Z 2 It is mixed after second element 222, and feed-in nib section 230.Above-mentioned first element 221 can be electricity with second element 222 Impedance caused by resistance element, inductance element, capacity cell (such as solid capacitor) or its any combination.In the implementation shown in Fig. 2A In example, the second impedance Z 2 can be changeless, and the first impedance Z 1 is variable, and corresponding to the variation of a certain sensor Amount.

In another embodiment, the first impedance Z 1 and the second impedance Z 2 are all variable, and the ratio value of both corresponds to The variable quantity of a certain sensor.In one embodiment, which can be telescopic elastic pen point, the first above-mentioned impedance Z1 can change corresponding to stroke or the stress degree of elastic pen point.In some examples, the first above-mentioned impedance Z 1 is linear Ground is corresponding to the variation of the physical quantity of sensor.But in other example, the first above-mentioned impedance Z 1 is non-linearly corresponding In the variation of the physical quantity of sensor.

It refer to the sequential signal for the modulating signal for shown in Fig. 9 B, being sender unit 110 according to an embodiment of the invention Figure.It is another deformation of Fig. 9 A embodiments.The step of being with the difference of Fig. 9 A, noise detecting carried out after the T1 periods. Then, then the detectings of other patterns is performed.

It refer to the sequential signal for the modulating signal for shown in Fig. 9 C, being sender unit 110 according to an embodiment of the invention Figure.The modulating signal of Fig. 9 C can be adapted for the sender unit 110 shown in Fig. 5, add in another function of ring electrode 550, just It is the signal strength strengthened when active pen suspends, with the suspension scope of sharp touch panel detection active pen.

The modulating signal of Fig. 9 C sends signal when being in suspended state by sender unit 110.In this case, sender unit 110 send in the signal frame of signal only comprising single a R periods.Within this R period, ring electrode 550 and nib section 230 can be with It is simultaneously emitted by electric signal.In one embodiment, these electric signals can come from same signal source, have identical frequency and/or Modulation mode.For example, ring electrode all sends the electric signal of the 3rd signal source 513 with nib.Again for example, ring electrode 550 jointly can sequentially send the first, second, electric signal with the 3rd signal source with nib section 230, each to be utilized respectively The maximum power of a signal source.Touch-control processing unit 130 is among the R periods, it is only necessary to detect what ring electrode 550 was sent Electric signal, it is possible to learn that sender unit 110 is just being suspended on some position of touch panel 120.If ring electrode 550 and pen The electric signal that apical segment 230 is sent is from identical signal source or has identical frequency group, and signal strength can be maximum, The suspension scope of touch panel detection stylus can so be made to reach maximum.Within the R periods among another embodiment, also may be used Only to send electric signal by ring electrode 550.

It refer to the sequential signal for the modulating signal for shown in Fig. 9 D, being sender unit 110 according to an embodiment of the invention Figure.The modulating signal of Fig. 9 D can be adapted for the sender unit 110 shown in Fig. 5.Among Fig. 9 C, one is included after the R periods Time delay or blank interval L1, afterwards touch panel carry out the detecting of other forms again.The embodiment of Fig. 9 D and the phase of Fig. 9 C Than the time of L1 periods is elongated.Fig. 9 D are compared with the embodiment of Fig. 9 E, L1 period of the length equal to Fig. 9 E of L1 periods, T0 Period, L2 periods, the summation of T1 periods and T3 periods.Therefore, if the touch-control processing unit 130 of Fig. 9 D is in regular length Detecting can then learn that sender unit 110 is in suspended state less than any electric signal in the L1 periods.

It refer to the sequential signal for the modulating signal for shown in Fig. 9 E, being sender unit 110 according to an embodiment of the invention Figure.The modulating signal of Fig. 9 E can be adapted for the sender unit 110 shown in Fig. 5.Fig. 9 E embodiments can be described as Fig. 9 A embodiments Signal frame front add the R periods.In this embodiment, touched regardless of whether nib section 230 has by pressure, sender unit 110 is same Electric signal is sent from nib in T0 periods and T1 periods, can thereby save the design of some logic circuits.But with Fig. 9 C and The embodiment of Fig. 9 D is compared, and the embodiment of Fig. 9 E can be wasted in the electric signal power that T0 periods and T1 periods are sent.From another From the point of view of aspect, touch-control processing unit 130 can also need not be detected in the R periods, as long as can be detected in T0 periods and T1 periods The electric signal sent to nib section 230 can learn whether nib section 230 is under pressure naturally, so as to learn sender unit Whether 110 be in suspended state.

It refer to the sequential signal for the modulating signal for shown in Fig. 9 F, being sender unit 110 according to an embodiment of the invention Figure.The modulating signal of Fig. 9 F can be adapted for the sender unit 110 shown in Fig. 5.In the embodiment of Fig. 9 E, there is no during restriction R Section and T0 periods, the proportionate relationship of the length of T1 periods.Among the embodiment of Fig. 9 F, R periods and T0 periods, the length of T1 periods Degree is than being 1:2:4.Thus, it is assumed that touch-control processing unit 130 can carry out n times sampling within the unit interval, and N is just whole Number.So within R periods and T0 periods, T1 periods, touch panel can carry out N:2N:4N sub-samplings.The present invention does not limit The length ratio of these three periods, for example, can allow the unit for sending the most strong period lasts minimum of electric signal power when Between, allow the period lasts longest unit interval for sending electric signal power minimum.For example, length ratio can be 1:3:2 or 1: 2:3 etc., end relies depending on design.Although among above-mentioned length, the modulation of T0 and two periods of T1 are only enumerated, the present invention The modulation of two periods is not limited to, and can be adapted for the modulation of more periods.

In one embodiment, sender unit 110 can nib not in contact with when send the larger electric signal of intensity, and work as Intensity smaller electric signal is sent when Stylus contact.Accordingly, touch-control processing unit 130 can be allowed to have larger probability detecting To the sender unit 110 for being suspended in 120 top of touch panel.It, can be with and after sender unit 110 touches touch panel 120 Save the energy that sender unit 110 is consumed.

Such as among the embodiment of Fig. 9 C and Fig. 9 D, that is, when nib section 230 is not touched, in the electricity that the R periods are sent Signal can be more than the electric signal sent the corresponding L1 periods to T0 periods and T1 periods.For example, among the R periods, by pen Apical segment 230 comes from the first signal source 211 with the electric signal that ring electrode 550 is sent, secondary signal source 212 and the 3rd is believed Number source 513.Therefore, the electric signal that the R periods are sent is the summation of these three signal sources 211,212 and 513 output.

And as Fig. 9 A embodiment among, table one for sender unit 110 in suspended state, use the first signal source 211 With the output power in secondary signal source 212.Table two is sender unit 110 in contact condition, T0 periods and T1 periods merely with To the first signal source 211 or the output power in secondary signal source 212.Therefore, sender unit 110 can nib not in contact with when The larger electric signal of intensity is sent, and intensity smaller electric signal is sent when Stylus contact.

Similarly, table three is sender unit 110 in suspended state, uses the first signal source 211 and secondary signal source 212 Output power.Table four is sender unit 110 in contact condition, in T0 periods and T1 periods merely with to the first signal source 211 Or the output power in secondary signal source 212.Therefore, sender unit 110 can nib not in contact with when to send intensity larger Electric signal, and intensity smaller electric signal is sent when Stylus contact.

Why to add in the step of noise is detected and period among the embodiment of Fig. 9 A to Fig. 9 F, refer to Figure 10 institutes Show, be noise transmission schematic diagram according to an embodiment of the invention.Among Figure 10, the electricity where touch panel/screen 120 Subsystem 100 itself can send the noise of f0 frequencies, and f0 frequencies are exactly a frequency among frequency group F0.It is assumed that frequency Rate group F0 further comprises another f3 frequency.When user holds the electronic system 100, the noise of f0 frequencies will be by making The finger of user is transferred on touch panel/screen 120.If the step of not carrying out noise detecting, then touch panel/screen 120 may be in the period of the signal frame f0 frequency signals that be transmitted finger by mistake, as being electric signal that sender unit 110 is sent. Therefore, if detecting the noise of f0 frequencies in advance, you can filter out the signal source of f0 frequencies with the period in signal frame.

Assuming that sender unit 110 has the function of automatic frequency-conversion, when sender unit 110 detects touch panel/screen 120 in itself The noise of f0 frequencies is had issued, and uses another f3 frequency of same frequency group F0 instead automatically.So that in the period of signal frame In, touch-control processing unit 130 detects the f3 frequencies for coming from sender unit 110 and the f0 frequencies for coming from finger, and then generates Obscure.Therefore, embodiment that can be as shown in Figure 9 B, in the case where obscuring, in the laggard of T1 periods or signal frame The step of noise detecting of row.Since sender unit 110 has stopped sending the signal of f3 frequencies, and finger and electronic system 100 still continuously send out the noise of f0 frequencies.Touch-control processing unit 130 can deduce, be detected within the script signal frame period To signal in, have f3 frequencies signal be just truly from the signal of sender unit 110.

It is the signal for changing to adjust multiple frequencies using the impedance of first element 221 among above-mentioned Fig. 2A explanations The ratio of intensity.It please refers to Fig.1 shown in 1, is the structure diagram according to first capacitance 221 of another embodiment of the present invention. The ratio of the signal strength of multiple frequencies is adjusted using the impedance change of the first capacitance 221.Traditional capacity cell is two panels Conductive metal sheet is formed.Its capacitivity C is directly proportional to metallic plate area with dielectric constant, and between metallic plate away from From being inversely proportional.

In one of main spirits of above-described embodiment, it is spring pen apical segment 230 using mechanical structure along sender unit The stroke of 110 axis directions changes into the row perpendicular to 110 axis direction of sender unit or with 110 axle center of sender unit into angle direction Journey.By the variation of the trip, change its corresponding first impedance Z 1 of capacitivity of the first capacitance 221, and fix and retain Its corresponding second impedance Z 2 of capacitivity of second capacitance 222 changes the letter of first frequency (group) among electric signal accordingly The ratio of the intensity M1 of number part and the intensity M2 of the signal section of second frequency (group).

Among Figure 11, include non-touching three metallic plates.First metallic plate 1110 and the second metallic plate 1120 The first capacitance 221 is formed, the second metallic plate 1120 and the 3rd metallic plate 1130 form the second capacitance 222.In an example, first Metallic plate 1110 is formed in flexible circuit board or printed circuit board, and surface has insulated paint or another layer of insulation Plate.Second metallic plate 1120 and the 3rd metallic plate 1130 are formed in two layers of same circuit board or printed circuit board, surface tool There are insulated paint or another layer of insulation board.Second metallic plate 1120 is couple to the nib section 230 in front via other circuit.Nib Be fixed in lifting element 1140 (incline device described as follows), according to nib section 230 the direct or indirect lifting part of displacement or Whole the first metallic plate 1110 (or circuit board or printed circuit board of elasticity) causes the first metallic plate 1110 (or elasticity Circuit board or printed circuit board) part towards perpendicular to 110 axis direction of sender unit deformation, be referred to as in the following description Perpendicular to the displacement of stylus axis direction.

Supplying the first metallic plate 1110 has the electric signal of first frequency (group), and the 3rd metallic plate 1130 of supply has the The electric signal of two frequencies (group).Therefore, the second metallic plate 1120, which can sense generation, has first frequency (group) and the second frequency The electric signal of rate (group) is transmitted to touch panel 120 via the nib section 230 in front.When 230 non-stress of nib section, First metallic plate 1110 and the circuit board belonging to it are not perpendicular to the displacement of 110 axis direction of sender unit.However, in nib section After 230 stress, due to the incline device 1140 after nib section, stress is converted into from the direction parallel to axle center perpendicular to axis The direction of the heart causes the circuit board belonging to the first metallic plate 1110 to deform upon and displacement, and then causes Jie of the first capacitance 221 Electric constant changes.So the capacitivity C1 of the first capacitance 221 also changes therewith with the first impedance Z 1.In nib section After 230 stress, the circuit board global displacement belonging to the second metallic plate 1120 and the 3rd metallic plate 1130, therefore the second capacitance 222 capacitivity C2 still remains unchanged with impedance Z 2.

Due to the circuit board where the first metallic plate 1110 can deformation upward, the present embodiment can include at least one and support Element 1150 in order to provide negative direction support force so that nib section 230 stress disappear after, help the first metallic plate Circuit board where 1110 restores to the original state.Before undeformed, the support force which is provided can be zero.

In the example of the present embodiment, the capacitivity of the first capacitance 221 and the second capacitance 222 can be designed to identical. In the case that capacitivity is identical, dielectric constant, distance and the area of the two capacitances can be identical.Certainly, it is of the invention The capacitivity for not limiting two capacitances 221 and 222 is identical, as long as touch-control processing unit 130 knows the sender unit 110 Two corresponding impedanoe ratios of capacitance.

In this embodiment, using cheap circuit board or printed circuit board power costly is substituted to sense resistance. Also, when the first capacitance 221 is identical with the capacitivity of the second capacitance 222, when external environment changes, dielectric constant also can Change simultaneously, maintain ratio preset value accordingly.In addition, sender unit 110 itself is not required active control elements to adjust Two impedance Zs 1 and the ratio of Z2, it is only necessary to electric signal be passively provided, many resources can be saved.
