The peristome of second direction lead 101a has first link 104 and second link 105 that connects external control component 100 in Fig. 1 C.In the present embodiment, second link 105 is serially connected with mode switch electronic switch 102, and this second link 105 can be connected to external control component 100 through mode switch electronic switch 102.(i.e. first lead and second lead) is electrically connected with a plurality of second capacitive coupling touch-control parts 103 on two limits of the U-shaped of second direction lead, and perhaps (first lead or second lead) is electrically connected with a plurality of second capacitive coupling touch-control parts 103 on arbitrary limit of the U-shaped of second direction lead.The quantity of these second capacitive coupling touch-control parts 103, size, shape are according to the requirements set of the circuit structure of reality.Certainly, the quantity of the second capacitive coupling touch-control parts 103 is identical with the point of crossing quantity of first direction lead group and second direction lead group.Be understandable that the second capacitive coupling touch-control parts 103 are identical with the quantity of the first capacitive coupling touch-control parts 203, and the first capacitive coupling touch-control parts in the sensor and the second capacitive coupling touch-control parts are staggered folded the establishing of first direction lead and the cross one another zone of second direction lead.
When the mode switch electronic switch 202 of first direction lead was closed, this first direction lead worked in the electromagnetic induction control mode touch mode, the electromagnetic signal of sending in order to the induced electricity magnetic pen.When all mode switch electronic switches 202 of first direction lead group are all closed, time writer is when vertically the moving up and down of first direction lead group, can measure the alternating signal of arbitrary first direction lead output by external control component, obtain relatively that lead location that the maximum alternating signal of output distributed in first direction lead group can directly be known and the accurate position of definite time writer vertical (be Y-axis to).Correspondingly, when the mode switch electronic switch 102 of second direction lead was closed, this second direction lead worked in the electromagnetic induction control mode touch mode, the electromagnetic signal of sending in order to the induced electricity magnetic pen.When all mode switch electronic switches 102 of second direction lead group are all closed, when time writer moves in the transverse horizontal of second direction lead group, can measure the alternating signal of arbitrary second direction lead output by external control component, obtain relatively that lead location that the maximum alternating signal of output distributed in second direction lead group can directly be known and the horizontal accurate position of (being X axis) of definite time writer.
Because first direction lead group and second direction lead group are intersected placements (structure as shown in the frame of broken lines of Figure 1A) mutually, so can detect the particular location that time writer is positioned at aerial array via the electromagnetic induction signal of both direction lead transmission.
What need further specify is that above-mentioned first direction lead group and second direction lead group are intersected mutually, constitute capacitive coupling touch-control aerial array simultaneously; And mutually insulated between first direction lead group and the second direction lead group.In the sensor shown in Figure 1A, all mode switch electronic switches (102 and 202) are disconnected, at this moment, first direction lead and second direction lead all work in the capacitive coupling control mode touch mode.Separately first link and outside connection control unit conducts in first direction lead and the second direction lead.After external control component receives capacitively coupled signal, the treated position of touch of knowing finger.Will be appreciated that, in the actual circuit structure that is provided with the present embodiment sensor, the mode switch electronic switch 102 and 202 in the sensor can be located at external control component 100 zones, so that the integrated control of entire circuit structure.

Below describe the principle of the aerial array identification electromagnetic signal among the sensor embodiment of the present invention in detail by Fig. 2 A to Fig. 2 C; Wherein, Fig. 2 A is the synoptic diagram of the Strength Changes of identification electromagnetic signal in the first direction lead, and Fig. 2 B is the synoptic diagram of the Strength Changes of identification electromagnetic signal in the first direction lead group, and Fig. 2 C is the synoptic diagram of aerial array identification electromagnetic signal.
In addition, shown in Fig. 2 B, the first direction lead 201a in the first direction lead group is with the equidistant from distance assembled arrangement, when verification experimental verification coil 5 is positioned at the vertical center of first direction lead 201a, and the alternation induced voltage U of first direction lead 201a output
3Maximum; And when moving to the vertical center of being partial to first direction lead 201b on the coil 5, the alternation induced voltage U of first direction lead 201b output
2Maximum; Further, when coil 5 moves to the vertical center of first direction lead 201c on again, the alternation induced voltage U of first direction lead 201c output
1Maximum.By on can in first direction lead group, obtain the positional information of coil 5 on vertical.That is to say, the first direction lead that a plurality of spacings that be arranged in parallel equate, and these a plurality of first direction leads that be arranged in parallel are distributed in the mode of assembled arrangement, and then externally pass through the relatively size of the alternation induced voltage of those first direction leads outputs in the control assembly, can obtain the accurate position of coil 5 on vertically.So, in the foregoing description the aerial array of sensor adopt as the first direction lead arranged among Fig. 2 B so that discern coil 5 preferably in vertically (Y-axis to) positional information accurately.
Same principle, in Fig. 2 C, coil 5 is positioned at the different horizontal level of second direction lead 101a, and the alternation induced voltage that its second direction lead 101a exports is different, so that obtain coil 5 positional information on (X axis) in the horizontal direction.
Shown in Fig. 2 C, aerial array comprises first direction lead group and the second direction lead group that square crossing is arranged.When the arbitrary position of coil 5,, can determine the particular location of coil 5 in aerial array by obtaining and the alternation induced voltage of first direction lead and the output of second direction lead in the aerial array relatively at aerial array.
Shown in figure 3A to Fig. 3 H, Fig. 3 A to Fig. 3 H is the principle analysis synoptic diagram of the capacitive coupling control mode touch mode among the sensor embodiment of the present invention; Wherein, conductor 21 can be equivalent to the finger of touch-control, and conductor 23 also insulate in identical aspect independently of one another with conductor 24.When conductor 21 fitted on conductor insulated from each other 23 and the conductor 24 by insulating medium 22, the conformable region equivalence of the left side of conductor 21 and conductor 23 was a capacitor C
1, the conformable region equivalence of the right side of conductor 21 and conductor 24 is a capacitor C
2, because conductor 21 is integrative-structures, and then the capacitor C of equivalence
1And capacitor C
2For being connected in series the equivalent electrical circuit shown in Fig. 3 C.Conductor 23 and 24 of conductors can transmit alternating voltage mutually as can be known from the equivalent electrical circuit shown in the 3C.Fig. 3 C shows the equivalent circuit diagram of the point of crossing in the finger touch aerial array among the present invention, because of finger and conductor 23 and 24 AC impedance of conductor (comprising induction reactance, impedance and/or capacitive reactance etc.) to the alternating voltage of certain frequency very big, be equivalent to insulation, and the dc impedance of finger is lower, so the touch face equivalence of hand is a conductor 21, first direction lead 201a is equivalent to conductor 23, and second direction lead 101a is equivalent to conductor 24.
Shown in Fig. 3 D, (be follow-up convenient explanation, only illustrated the synoptic diagram of a first direction lead and the square crossing of a second direction lead among Fig. 3 D), when first link 104 of the 101a of second direction lead feeds alternating signals 8, finger contacts with point of crossing 1 (dash area among Fig. 3 D), so that being switched on, the loop of AC signal 8 (that is to say the capacitor C between the touch point 1 among Fig. 3 D
7And C
8Conducting), can get access to the alternating signal 9 of first link, 204 outputs of first direction lead 201a thus.When the point of crossing shown in finger touch Fig. 3 D 2,3 or 4, the C of corresponding contact point 2

2, contact point 3 C
3And C
4, or the C of contact point 4
6And C
5Be switched on, and then can detect above-mentioned alternating signal 9.From the above mentioned, the capacitive coupling touching signals of external control component in can the identification aerial array.
Because each first direction lead and second direction lead all have four intersection points, the position of its output alternating signal 9 also is identical, shown in above-mentioned Fig. 3 D possibly can't judge preferably finger be positioned at the particular location of point of crossing (being touch point) 1,2,3 or 4, so obtain unique positional information under the capacitive coupling pattern below in conjunction with 3E to Fig. 3 H detailed description external control component.
Shown in Fig. 3 E to Fig. 3 H, conductor 21 and conductor 23 among Fig. 3 E, conductor 21 and 24 binding face equate, i.e. C

2Equate that conductor 21 is unequal with the binding face of conductor 23, conductor 24 among Fig. 3 F and Fig. 3 G, and then C
1Bigger in Fig. 3 F and Fig. 3 G, because conductor 21 is certain with the applying total area of conductor 23 and 24, and C

2When equating, the alternating signal of output is the strongest, each experimental data shown in Fig. 3 H, its S1＞S2＞S3.When replacing conductor 21 with finger, the result of its generation is consistent with the result of above-mentioned simulated experiment.
So, because actual sensor comprises 3 above U-shaped first direction leads and second direction lead at least, so in the concrete structure, each point of crossing is respectively by the first capacitive coupling touch-control parts 203 and the second capacitive coupling touch-control parts, 103 staggered folded establishing, and each point of crossing in the aerial array evenly distribute (shown in following Fig. 7 C), and then the point of crossing that can guarantee finger touch is at least two or more, so that make external control component by obtaining and the position of the alternating signal of the maximum of first link output of more adjacent all directions lead, (that is to say with the accurate location information of knowing touch point, by means of the distribution of the alternating signal of adjacent intersections output in first link output of all directions lead, the accurate touch point 1 among the component- bar chart 3D, 2,3 and 4), thus, two the adjacent at least point of crossing that comprise by touch point can unique definite capacitive coupling control mode touch mode under the positional information of touch point.
Need to prove, distance between the large part of human body and hand and the point of crossing of aerial array is much bigger with respect to the distance between finger and the point of crossing, and then induction reactance, capacitive reactance, impedance that the point of crossing of the large part of human body and hand and aerial array produces all are very large, so with respect to the capacitive reactance that finger produces in the point of crossing, can insulate in other positions of health in equivalence.

B5Greater than being coupled to first direction lead 201b (B8, alternating voltage U b8)
B8Shown in Fig. 4 A1, as with touch point 1 progressively along moving on the Y-axis, touch point 1 and first direction lead 201a (B5, binding face b5) can gradually reduce, with first direction lead 201b (B8, b8) it is big that binding face can progressively become, (A5, a5) alternating voltage 8 on is coupled to first direction lead 201a (B5, alternating voltage U b5) by touch point 1 to second direction lead 101a so
B5Can progressively reduce, be coupled to first direction lead 201b (B8, alternating voltage U b8)
