[0002] A mutual capacitance touch device includes driving electrodes (TX) and sensing electrodes (RX) that are crossed in rows and columns. A coupling capacitor is generated at the intersection of the driving electrodes and the sensing electrodes. When a finger touches the touch device, the coupling capacitor at the touch position changes. The touch position of the finger can be determined by detecting the change in coupling capacitor through a touch driver chip (IC).

[0003] The driving electrodes are connected one-to-one with the driving electrode wires located around them, and are connected to the touch driving chip through the driving electrode wires. The sensing electrodes are connected one-to-one with the sensing electrode wires located around them, and are connected to the touch driving chip through the sensing electrode wires. At present, all the sensing electrodes of the touch control device are connected to the sensing electrode wires on the same side of the touch control area of ​​the touch control device. Under this connection mode, when scanning the sensing electrodes, only one sensing electrode can be scanned at a time.

[0004] When the existing touch control device is working, multiple driving electrodes are scanned in sequence, and multiple sensing electrodes are scanned in sequence within the scanning time period of one driving electrode.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present disclosure.

[0039] Please refer to Figure 1 , Figure 1 The structure diagram of a touch control substrate according to an embodiment of the present disclosure is as follows. The touch control substrate includes:

[0040] A base substrate 10, wherein the base substrate comprises a touch area 11 and a wiring area 12 located around the touch area 11; Figure 1 The area indicated by the middle dotted line is the touch area 11 .

[0041] A plurality of sensing electrodes 20 are located in the touch control area 11;

[0042] A plurality of sensing electrode wirings 30 are located in the wiring area 12 and are connected one-to-one with the plurality of sensing electrodes 20;

[0043] The sensing electrode 20 includes a first sensing electrode 21 and a second sensing electrode 22. The first sensing electrode 21 is connected to the sensing electrode trace 30 from a first side of the touch area 11, and the second sensing electrode 22 is connected to the sensing electrode trace 30 from a second side of the touch area 11. The first side and the second side are opposite sides of the touch area 11.

[0044] Figure 1 In the embodiment described above, the plurality of sensing electrodes 20 are arranged in rows, the first sensing electrodes 21 are connected to the sensing electrode traces 30 from the right side of the touch control area 11, and the second sensing electrodes 22 are connected to the sensing electrode traces 30 from the left side of the touch control area 11. In some other embodiments of the present disclosure, the plurality of sensing electrodes 20 may also be arranged in columns, in which the first sensing electrodes 21 may be connected to the sensing electrode traces 30 from the upper side of the touch control area 11, and the second sensing electrodes 22 may be connected to the sensing electrode traces 30 from the lower side of the touch control area 11.

[0045] In the disclosed embodiment, a portion of the sensing electrodes are connected to the sensing electrode wiring at one side of the touch area, and another portion of the sensing electrodes are connected to the sensing electrode wiring at the other side opposite to the touch area. In this connection mode, two sensing electrodes can be scanned each time, which can reduce the scanning cycle of the sensing electrodes.

[0046] How to scan two sensing electrodes at a time to reduce the scanning period of the sensing electrodes is explained as follows: when performing touch detection, a sensing signal can be applied to and detected on a first sensing electrode and a second sensing electrode at the same time within the scanning period of a driving electrode. Since the sensing signals in the first sensing electrode and the second sensing electrode are respectively input from different sides of the touch area, at a certain moment, the sensing signal of only one of the first sensing electrode and the second sensing electrode can reach the position of the currently scanned driving electrode, so that it can be distinguished which sensing electrode corresponds to the current touch position. Since two sensing electrodes can be scanned at the same time, assuming that the number of driving electrodes is M and the number of sensing electrodes is N, at this time, a scanning period is T1*T2*1 / 2, T1 is the scanning time of M driving electrodes, T2*1 / 2 is the scanning time of N sensing electrodes, and T2 is the scanning time according to the existing scanning method of scanning one sensing electrode each time. It can be seen that compared with the existing touch device, the scanning period of the touch substrate in the embodiment of the present disclosure is reduced by half, thereby improving the touch response speed and sensitivity.

[0047] In some embodiments of the present disclosure, optionally, if the number of the sensing electrodes is an even number, the number of the first sensing electrodes and the number of the second sensing electrodes are the same. That is, the number of sensing electrode lines on the first side and the second side of the touch area is the same, so that the sensing electrodes are conveniently grouped into twos, and a group of sensing electrodes can simultaneously apply and detect sensing signals.

[0048] In some embodiments of the present disclosure, optionally, if the number of the sensing electrodes is an odd number, the difference between the number of the sensing electrodes in the first part and the number of the sensing electrodes in the second part is 1. That is, the number of sensing electrode lines on the first side and the second side of the touch area is the same, and in this case, except for one of the sensing electrodes, the other sensing electrodes form a group of two, and a group of sensing electrodes can apply and detect sensing signals at the same time.

[0049] In some embodiments of the present disclosure, optionally, the first sensing electrode is an odd-numbered sensing electrode among the plurality of sensing electrodes; and the second sensing electrode is an even-numbered sensing electrode among the plurality of sensing electrodes. That is, two adjacent sensing electrodes are connected to touch electrode traces on different sides of the touch area, so that the two adjacent sensing electrodes can be grouped together, and a group of sensing electrodes can simultaneously apply and detect sensing signals. For example, Figure 1In the illustrated embodiment, the first, third, fifth and seventh sensing electrodes are first sensing electrodes, and the second, fourth and sixth sensing electrodes are second sensing electrodes.

In which, each of the sensing electrodes 20 or each of the driving electrodes 40 includes a plurality of conductive patterns disconnected from each other in the same layer.

[0065] In the embodiment of the present disclosure, since the sensing signals in the first sensing electrode and the second sensing electrode are input from different sides of the touch area, at a certain moment, the sensing signal of only one of the first sensing electrode and the second sensing electrode can reach the position of the currently scanned driving electrode, so that it is possible to distinguish which sensing electrode corresponds to the current touch position. Since two sensing electrodes can be scanned at the same time, assuming that the number of driving electrodes is M and the number of sensing electrodes is N, at this time, a scanning cycle is T1*T2*1 / 2, T1 is the scanning time of M driving electrodes, T2*1 / 2 is the scanning time of N sensing electrodes, and T2 is the scanning time according to the existing scanning method of scanning one sensing electrode each time.
