Referring to fig. 6, in an operation period of the first mode, the first electrode unit 23 sends n2Second first downlink signal Sdown1The second electrode unit 24 transmits m2Second downlink signal Sdown2Wherein n is2Greater than m2In the present embodiment, m2Is 1, i.e. in the working period, the second electrode unit 24 sends the second downlink signal S oncedown2Each time the second downlink signal Sdown2Is overlapped with the first downlink signal S oncedown1I.e. the second downlink signal Sdown2Corresponding to the first downlink signal S of the timedown1The synchronous transmission is started and finished, and the touch isControl device 10 with i3A first period T1To receive said first downlink signal Sdown1And with j3A second period of time T2To receive said second downlink signal Sdown2Wherein i3Is greater than j3And i is3Less than n2Each of the first time periods T1Is equal to each of the second periods T2And is also equal to the time period of sending the first downlink signal S each timedown1The length of time of (c).
Referring to fig. 7, in an operation period of the first mode, the first electrode unit 23 sends n3Second first downlink signal Sdown1The second electrode unit 24 transmits m3Second downlink signal Sdown2Wherein n is3Is equal to m3Each time said second downlink signal Sdown2Is not overlapped with the first downlink signal S at each timedown1I.e. the input means 10 is transmitting said second downlink signal Sdown2While not transmitting the first downlink signal Sdown1While transmitting the first downlink signal Sdown1While not transmitting the second downlink signal Sdown2. In the present embodiment, the input device 10 transmits the first downlink signal S in a staggered mannerdown1And said second downlink signal Sdown2And in the present embodiment, the first downlink signal S is transmitted each timedown1Is equal to the time length of transmitting the second downlink signal S each timedown2And the touch device 10 uses i4A first period T1To receive said first downlink signal Sdown1And with j4A second period of time T2To receive said second downlink signal Sdown2The first period T1And the second period of time T2Interleaved execution, wherein i4Is equal to j4And i is4Is equal to n1Each of the first time periods T1Is equal to each of the second periods T2And is also equal to each time the first downlink signal S is transmitteddown1The length of time of (c).
Further, the total time length that the touch device 10 can receive the downlink signal sent by the first electrode unit 23 in the first mode (the input device 20 is in contact with the touch device 10) and the second mode (the input device 20 is suspended in the touch device 10) is compared, since the time in the first mode is allocated to receiving the first downlink signal Sdown1And said second downlink signal Sdown2Then, the touch device 10 is used to receive the third downlink signal S in the second modedown3The total time length of the first downlink signal S is necessarily longer than the total time length of the first downlink signal S received by the touch device 10 in the first modedown1The total length of time of (c). Considering that the downlink signal sent by the first electrode unit 23 is used for the touch device 10 to determine the information of the position of the input device 20, but since the second mode is a case where the input device 20 is relatively suspended in the touch device 10, i.e. the distance between the two is relatively long, the amount of induction of the downlink signal sent from the input device 20 received by the touch device 10 is relatively small, which is easy to affect the signal-to-noise ratio (SNR), the touch device 10 of the embodiment has more time to receive the downlink signal related to the position information of the input device 20 when the input device 20 corresponds to the second mode, which can improve the signal-to-noise ratio (SNR), and further improve the accuracy of the touch device 10 determining the position of the input device 20.
Specifically, taking fig. 3 and 4 as an example, in the first mode (fig. 3), the touch device 10 is represented by i1A first period T1To receive said first downlink signal Sdown1In the second mode (fig. 4), the touch device 10 is operated at k1A third period of time T3To receive said third downlink signal Sdown3Wherein each first period T1Is equal to each third period T3Length of time of (c), but k1Greater than i1Therefore, the touch device 10 is used to receive the third downlink signal S in the second modedown3Is longer than the total time period of the touch device 10 receiving the first downlink signal S in the first modedown1Is long in total timeAnd (4) degree.
For another example, referring to fig. 4 and 5, in the first mode (fig. 5), the touch device 10 uses i2A first period T1To receive said first downlink signal Sdown1In the second mode (fig. 4), the touch device 10 is operated at k1A third period of time T3To receive said third downlink signal Sdown3Wherein k is1Is equal to i2But each of the first periods T1Is less than each of the third time periods T3So that the touch device 10 is used to receive the third downlink signal S in the second modedown3Is still longer than the total time period of the touch device 10 for receiving the first downlink signal S in the first modedown1The total length of time of (c).
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
