Embodiment
Fig. 1 shows the active pen of the reduction joint sheet number of the embodiment of the present invention（active pen）Integrated circuit（IC）
11 block diagram.The active integrated circuit 11 of the present embodiment is applicable to running gear 12, such as intelligent mobile phone.This reality
Joint sheet number needed for applying active integrated circuit 11 of example is much smaller than active pen collection used in Traditional mobility device
Into circuit.
Active integrated circuit 11 includes multiple joint sheets 111, to receive multiple receptions（RX）Signal, it senses certainly
Running gear 12.The number of RX signals is approximately identical to the number of joint sheet 111.In the present embodiment, the integrated electricity of active pen
Road 11 includes arrangement units 112, to arrange joint sheet 111（That is, change the order of joint sheet 111）.Arrangement units 112 can
Use software and hardware（Such as circuit）, such as processor, to implement.Because the present embodiment has used arrangement units 112 so that
（Active integrated circuit 11）The number of joint sheet 111 can be much smaller than the integrated electricity of conventional active pen for having equal resolution
The joint sheet number on road.Therefore, a large amount of circuit areas or increase resolution ratio or size can be saved.
In simplified example, active integrated circuit 11 has seven joint sheet P1~P7, to receive seven RX letters
Number X1~X7.These RX signals X1~X7The first original RX ensembles are constituted, and are respectively corresponding to joint sheet P1~P7.Arrangement is single
Member 112 is then to joint sheet P1~P7Arranged, for example, produce and put in order as P2、P4、P6、P1、P3、P5、P7, it is right respectively
Should be to RX signals X8~X14.These RX signals X8~X14Constitute the 2nd RX ensembles produced.Fig. 2A illustrates RX signals X1~X14
And corresponding joint sheet P1~P7.One of feature according to the present embodiment, by arranging joint sheet 111 so that any joint sheet and
Its adjacent bond pad is combined in every RX ensembles（Such as original the first RX ensembles and the 2nd RX ensembles of generation）
It is different from.
As illustrated in Fig. 2A, two maximum RX signals X are there are3With X12（One from the first original RX ensembles, it is another then
The 2nd RX ensembles from generation）, correspondence to joint sheet P3.In order to determine pen position among the two maximum RX signals
Put, it is necessary to further select second largest RX signals X1/X11（Corresponding to P1）And the third-largest RX signals X5/X13（Corresponding to P5）, such as scheme
Illustrated in 2B.In fig. 2b, second largest RX signals X11, the third-largest RX signals X13And maximum RX signals X12Collectively constitute normality point
Match somebody with somebody（normal distribution）, wherein signal voltage is from peak value（That is, X12）Second Largest Value is gradually reduced to respectively（That is,
X11）And the third-largest value（That is, X13）.On the other hand, second largest RX signals X5, the third-largest RX signals X3And maximum RX signals X3Then
Fail composition normality distribution, because signal voltage fails from peak value（That is, X3）Second Largest Value is gradually reduced to respectively（That is, X1）
And the third-largest value（That is, X5）.It is possible thereby to learn, a position occurs in RX signals X12Corresponding position.
Fig. 3 illustrates 21 RX signals X1~X21, it is produced from seven joint sheet P1~P7, schema display RX signals X1
~X21With arrangement joint sheet P1~P7Between relation.In details of the words, it is received from the RX signals X of running gear 121~X7Constitute former
The first RX ensembles begun.Arrangement units 112 are then to joint sheet P1~P7Arranged, generation puts in order as P2、P4、P6、
P1、P3、P5、P7, it is respectively corresponding to RX signals X8~X14.These RX signals X8~X14Constitute the 2nd RX ensembles produced.Row
Column unit 112 is again to joint sheet P1~P7Arranged, generation puts in order as P3、P6、P2、P5、P1、P4、P7, it is corresponded to respectively
To RX signals X15~X21.These RX signals X15~X21Constitute the 3rd RX ensembles produced.
One of feature according to the present embodiment, as illustrated in fig. 3, in different RX ensembles, adjacent two joint sheet away from
From differing.For example, in the first RX ensembles, adjacent two joint sheet（Such as P2With P3）Distance be 1（=3-2）；In the 2nd RX
Ensemble, adjacent two joint sheet（Such as P4With P6）Distance be 2（=6-4）；In the 3rd RX ensembles, adjacent two joint sheet（Example
Such as P3With P6）Distance be 3（=6-3）.Furthermore, in different RX ensembles, any joint sheet two joint sheet adjacent thereto（One
It is another adjacent to the right adjacent to the left side）Combination differ.Generally, for N number of RX signals and B joint sheet（B is most
It is prime number well）, then N and B have following relation：N=B [B/2], wherein [] is round numbers（Or Gauss）Operator.
Fig. 4 illustrates 39 RX signals X1~X39, it is produced from 13 joint sheet P1~P13, schema display RX signals
X1~X39With arrangement joint sheet P1~P13Between relation.In details of the words, it is received from the RX signals X of running gear 121~X13Structure
Into the first original RX ensembles.Arrangement units 112 are then to joint sheet P1~P13Arranged, generation puts in order as P3、
P6、P9、P12、P2、P5、P8、P11、P1、P4、P7、P10、P13, it is respectively corresponding to RX signals X14~X26.These RX signals X14~X26
Constitute the 2nd RX ensembles produced.Arrangement units 112 are again to joint sheet P1~P13Arranged, generation puts in order as P4、
P8、P12、P3、P7、P11、P2、P6、P10、P1、P5、P9、P13, it is respectively corresponding to RX signals X27~X39.These RX signals X27~X39
Constitute the 3rd RX ensembles produced.
One of feature according to the present embodiment, as exemplified in figure 4, in different RX ensembles, adjacent two joint sheet away from
From differing.For example, in the first RX ensembles, adjacent two joint sheet（Such as P2With P3）Distance be 1（=3-2）；In the 2nd RX
Ensemble, adjacent two joint sheet（Such as P3With P6）Distance be 3（=6-3）；In the 3rd RX ensembles, adjacent two joint sheet（Example
Such as P4With P8）Distance be 4（=8-4）.Furthermore, in different RX ensembles, any joint sheet four joint sheet adjacent thereto（Secondly
Adjacent to the left side, another two adjacent to the right）Combination differ.Generally, for N number of RX signals and B joint sheet（B is most
It is prime number well）, then N and B have following relation：N=B [B/4], wherein [] is round numbers（Or Gauss）Operator.
The preferred embodiments of the present invention are the foregoing is only, the scope of the present invention is not limited to；It is all it is other not
Depart from the equivalent change or modification completed under the spirit disclosed in invention, should be included in the scope of following claims
