Due to the first radio-frequency (RF) signal SIG
1and the second radio-frequency (RF) signal SIG
2frequency mutually orthogonal, therefore analytic unit 132 can utilize Fast Fourier Transform (FFT) (fastFouriertransform) to analyze the frequency of signal received by each first sense wire 102 and each the second sense wire 104, and unlikely affected by noise causing judges by accident.In other embodiments, analytic unit 132 also can according to bandpass filter, or the frequency of received signal analyzed by inphase/orthogonal phase converter (in-phase/quadraturedemodulator, I/Qdemodulator).
In addition, the second radio-frequency (RF) signal SIG that pointer 120 sends received by a plurality of first sense wires 102 and a plurality of the second sense wires 104
2be outside from contact panel, be therefore easier to produce noise, for avoiding this problem, in embodiments of the invention, the second radio-frequency (RF) signal SIG
2frequency can higher than the first radio-frequency (RF) signal SIG
1frequency, to reduce noise to the second radio-frequency (RF) signal SIG
2impact.
If for detecting finger and the touch-control of pointer simultaneously, then detect at touch-control receiver 110 the second radio-frequency (RF) signal SIG that pointer 120 sends
2after, transceiver mode controller 112 first can end a plurality of switch 106 to be stopped sending the first radio-frequency (RF) signal SIG via a plurality of the first sense wires 102 to make transmitter 108
1, now, touch-control receiver 110 can receive the second radio-frequency (RF) signal SIG according in a plurality of first sense wires 102
2the first sense wire 102 and a plurality of the second sense wires 104 in receive the second radio-frequency (RF) signal SIG
2the second sense wire 104, produce contact panel 100 by the position of pointer 120 touch-control; And after generation contact panel 100 is by the position of pointer touch-control, the transceiver mode controller 112 meeting a plurality of switch 106 of conducting again, and control transmitter 108 sequentially sends the first radio-frequency (RF) signal SIG via the first sense wire 102
1contact panel 100 is detected by the position of finger touch to make touch-control receiver 110.By the control of transceiver mode controller 112 pairs of transmitters 108, a plurality of switch 106 and touch-control receiver 110, contact panel 100 can be detected in turn and pointed or the position of pointer 120 touch-control.

Fig. 2 is the schematic diagram of another embodiment of the present invention touch sensing 20.Touch sensing 20 has identical principle of operation with touch sensing 10, and its difference is only that the contact panel 200 of touch sensing 20 comprises plural groups first sense wire 202A, and each is organized the first sense wire 202A and then contains a plurality of the first sense wires 202.
When not knowing that user is when using finger touch or pointer 120 touch-control, transceiver mode controller 112 can first conducting a plurality of switch 106, and control transmitter 108 sequentially sends the first radio-frequency (RF) signal SIG via plural groups first sense wire 202A
1, namely first send the first radio-frequency (RF) signal SIG via a plurality of first sense wires 202 of first group of first sense wire 202A simultaneously
1, then send the first radio-frequency (RF) signal SIG via a plurality of first sense wires 202 of second group of first sense wire 202A simultaneously
1, by that analogy, the first radio-frequency (RF) signal SIG that a plurality of first sense wires 202 wherein in arbitrary group of the first sense wire 202A send
1orthogonal, and the first radio-frequency (RF) signal SIG that the first sense wire 202 of different group of identical sequence sends
1can be the signal of same frequency, as kth article first sense wire 202 of m group first sense wire 202A and the kth article first radio-frequency (RF) signal SIG that the first sense wire 202 sends of n-th group of first sense wire 202A
1identical frequency can be had, wherein m ≠ n and m, n and k are all positive integer.When control transmitter 108 sequentially sends the first radio-frequency (RF) signal SIG via plural groups first sense wire 202A
1time, a plurality of second sense wires 104 can receive the first radio-frequency (RF) signal SIG that plural groups first sense wire 202A sends
1.If now user is with finger touch contact panel 200, then contact panel 200 can be changed by the capacitance size near the position A of finger touch, therefore can receive amplitude close to the second sense wire 104 of A point and be less than the first radio-frequency (RF) signal SIG
1but frequency and the first radio-frequency (RF) signal SIG
1the 3rd identical radio-frequency (RF) signal SIG
3, when touch-control receiver 110 detects this 3rd radio-frequency (RF) signal SIG
3time, transceiver mode controller 112 can control touch-control receiver 110 and send the first radio-frequency (RF) signal SIG according in plural groups first sense wire 202A at that time
1the first sense wire 202 and a plurality of the second sense wires 104 in receive the 3rd radio-frequency (RF) signal SIG
3the second sense wire 104 produce contact panel 100 by the position of touch-control.Due to the first radio-frequency (RF) signal SIG that a plurality of first sense wires 202 in arbitrary group of the first sense wire 202A are launched
1orthogonal, therefore analytic unit 132 can utilize Fast Fourier Transform (FFT) (fastFouriertransform) analyze simultaneously a plurality of the second sense wires 104 receive the first radio-frequency (RF) signal SIG sent from a plurality of first sense wires 202 in same group of the first sense wire 202A
1frequency and amplitude, and unlikely affected by noise cause erroneous judgement.In other embodiments, analytic unit 132 also can according to bandpass filter, or inphase/orthogonal phase converter (in-phase/quadraturedemodulator) is analyzed.So just can save in FIG, the transmitter 108 of touch sensing 10 sends the first radio-frequency (RF) signal SIG one by one on a plurality of first sense wires 102
1time.
And in above process, if touch-control receiver 110 detects the second radio-frequency (RF) signal SIG that pointer 120 sends
2, represent that user indicates the position of touch of contact panel 100 for using pointer 120, now transceiver mode controller 112 can end a plurality of switch 106 and stops sending the first radio-frequency (RF) signal SIG via plural groups first sense wire 202A to make transmitter 108
1simultaneously, transceiver mode controller 112 can control touch-control receiver 110 and receives and analyze from the signal received by plural groups first sense wire 202A and a plurality of the second sense wires 104, and touch-control receiver 110 then can receive the second radio-frequency (RF) signal SIG according in plural groups first sense wire 202A
2the first sense wire 202 and a plurality of the second sense wires 104 in receive the second radio-frequency (RF) signal SIG
2the second sense wire 104, produce contact panel 200 by the position of touch-control.Due to the first radio-frequency (RF) signal SIG
1and the second radio-frequency (RF) signal SIG
2frequency mutually orthogonal, therefore analytic unit 132 can go out the first radio-frequency (RF) signal SIG respectively
1and the second radio-frequency (RF) signal SIG
2frequency and amplitude, and produce correct position of touch.
