[0052] In the following, when drive signals are applied to a plurality of drive electrodes TX0, TX1, TX2, and TX3, For convenience of explanation, the operation of the first receiving electrode RX1 and the sensing unit 1 of FIG. The operation of step 1 will now be described in detail.

[0053] When a driving signal is applied to the driving electrodes TX0, TX1, TX2, and TX3, the first connection Two sensing signals are output via the pattern P1. The first signal is output via the first connecting pattern P1. a, and the second signal is output via the second connection pattern P1b. Therefore, for each receiving electrode RX0, RX1, RX2, RX3, and RX4, The first and second signals of two channels are outputted at the same time. The first and second signals may be output to the sensing unit 11 of FIG.

[0054] A first signal is generated by the drive electrodes TX0, TX1, TX2, TX3, . . . to which the drive signals are applied. and the second signal is an active channel signal (or an active received signal ARX ), and the remaining one may be a dummy channel signal (or a dummy received signal DRX Specifically, the driving electrode RX1a of the first group is arranged When a driving signal is applied to the electrodes TX0 and TX2, it is output via the first connecting pattern P1a. The first signal becomes an active channel signal and is output via the second connection pattern P1b. On the other hand, the second signal received by the receiving electrode pattern RX of the second group is a dummy channel signal. When a driving signal is applied to the driving electrodes TX1 and TX3 where the second connecting pattern 1b is arranged, The second signal output via P1b becomes the active channel signal, and the first connection pattern The first signal output via P1a is a dummy channel signal.

[0055] For example, as shown in FIG. 2, a driving signal is applied to the first driving electrode TX1, and the object The point (dotted line) is close to or in contact with the intersection of the first drive electrode TX1 and the first receiving electrode RX1. Assuming that, the receiving electrode pattern RX1 belonging to the second group of the first receiving electrode RX1 b and the first drive electrode TX1. The second signal containing the capacitance change information is transmitted to the active channel. The second signal is output via the second connecting pattern P1b. It may include an LGM noise signal and a display noise signal from the display panel.

[0056] Then, between the first receiving electrode RX1 and the receiving electrode pattern RX1a belonging to the first group The capacitance (or dummy capacitance) formed in the capacitor also changes. The first signal including the amount of change in the signal is a dummy channel signal, and the first concatenation pattern P1a is used. Here, the first signal includes an LGM noise signal and a display panel. Here, the display noise signal due to contact with the object (dotted line) may be included. The receiving electrode pattern RX1b belonging to the second group and the receiving electrode pattern RX1b belonging to the first group Since the cross-sectional areas of the RX1a and RX2a are the same, they each produce nearly identical or similar LGM noise signals. may be input, and a display noise signal from a display panel may also be input almost identically. It is okay to do so.

[0057] The sensing unit 11 shown in FIG. 1 detects a second signal outputted through the second connection pattern P1b. By subtracting the first signal output via the first connection pattern P1a, the second Receiving electrode pattern RX1b belonging to the group and receiving electrode pattern R belonging to the first group The LGM noise signal input to the X1a and the display noise signal can be canceled out. The subtraction is performed to obtain the active channel signal included in the second signal. The capacitance change amount varies slightly depending on the dummy capacitance change amount included in the first signal. However, the distance between the first drive electrode TX1 and the receiving electrode pattern RX1a is Since the distance between TX1 and the receiving electrode pattern RX1b is relatively farther, The dummy capacitance change amount included in Therefore, the subtracted active capacitance change The amount alone is sufficient to detect the presence or absence and / or location of a touch.

[0058] On the other hand, if the drive signal is applied to the 0th drive electrode TX0, not the first drive electrode TX1, On the other hand, the sensing unit 11 shown in FIG. 1 outputs the first signal ( The second signal (dummy active channel signal) is output via the connection pattern P1b. By subtracting the signal from the receiving electrode pattern RX1a belonging to the first group, The LGM noise signal and the discontinuity signal input to the receiving electrode pattern RX1b belonging to the second group are It is possible to cancel out the play noise signal. It can remove various noises that may occur, such as display noise and LGM noise. There is an advantage to being able to do this.
