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 utility model; 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 in the utility model, 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 1And C 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 1And 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 1And C 2So series connection is according to series capacitance C=C 1* C 2/ (C 1+ C 2) as can be known, have only C 1And 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.
