The touch units 130 are arranged in a matrix manner to form a plurality of touch rows 110 and a plurality of touch columns 120, and the touch rows 110 and the touch columns 120 are arranged to intersect with each other to form a touch area 110. The touch column 110 is an X column, and the touch column 110 includes a first touch column 111, a second touch column 112, a third touch column 113, and a fourth touch column 114 … …, an mth touch column.

Each of the spacing columns 150 is disposed between two adjacent touch columns 120, so that there are a plurality of spacing columns 150, specifically, (Y-1), for example, Y is 18, and the spacing columns 150 are 17.

In some embodiments, the spacing of the plurality of inter-rows 140 is the same, or the spacing of the plurality of columns 150 is the same. The pitch of the plurality of inter-rows 140 may be the same, and the pitch of the plurality of columns 150 may be the same.

In some embodiments, the touch unit 130 is rectangular. Of course, the shape may be circular, square, elliptical, polygonal, etc.

The touch units are divided into a plurality of groups of touch units, each group of touch units comprises a first touch unit and a second touch unit, and each group of touch units corresponds to one touch connecting line;

the first touch control unit is directly connected with the touch control connecting line; the second touch control unit is connected with the touch control connecting line through the first conversion circuit so as to convert an original signal input into the first conversion circuit into a first conversion signal, and the waveform shape and/or intensity of the first conversion signal are different from those of the original signal.

Specifically, first, the touch units 130 are divided into a plurality of touch unit groups 140, each touch unit group 140 includes a first touch unit 131 and a second touch unit 132, and each touch unit group 140 corresponds to one touch connecting line 15. The first touch unit 131 is directly connected to the touch connection line 15, the original signal triggered by the first touch unit 131 is directly transmitted to the touch connection line 15, the second touch unit 132 is connected to the touch connection line 15 through the first conversion circuit 200, the first conversion circuit 200 converts the original signal input to the first conversion circuit 200 into a first conversion signal, and the waveform shape and/or intensity of the first conversion signal is different from the original signal.

In the embodiment of the present invention, when the touch area 100 is actually touched, i.e. when the touch units 130 are triggered by external touch, e.g. by a finger of a user, the touch units 130 are generally touched to multiple touch units 130, e.g. two touch units 130 are touched at a time, if the two touch units 130 are different touch units 140, one of the first touch units 131 is a first touch unit 131 and the other is a second touch unit 132, an original signal triggered by the first touch unit 131 is directly transmitted to the touch connection line 15 and then transmitted to the touch chip 12, the original signal triggered by the second touch unit 132 is transmitted to the touch connection line 15 through the first conversion circuit 200, the first conversion circuit converts a signal transmitted by the second touch unit 132 into a first conversion signal, and the waveform shape and/or intensity of the first conversion signal is different from the original signal.

For example, the signal is not triggered to be a low level signal, and is a high level signal after being triggered, after passing through the first conversion circuit 200, the triggered high level signal becomes a rectangular pulse signal, the touch chip 12 first confirms the position of the touch unit group 140 according to the received signal, and then confirms the position of the touch unit 130 according to the obtained signal. If both of the touch units 130 are the first touch unit 131 or the second touch unit 132, the position of the touch unit group 140 is determined, and then the first touch unit 131 or the second touch unit 132 of the touch unit group 140 is determined according to the received signal, so as to determine the positions of the two touch units 130. If the two touch units 130 are of the same touch unit group 140, the signals of the two touch units 130 are superimposed to obtain a new signal, and the touch chip 12 recognizes the superimposed signal and knows that both touch units 130 of the touch unit group 140 are triggered. If the two touch units 130 are in the same touch unit group 140, the first touch unit 131 and the second touch unit 132 may be connected to the touch connection line 15 through a switch, only the first touch unit 131 or the second touch unit 132 may be connected to the touch connection line 15 at the same time through the switch, the switch may be composed of an NMOS and a PMOS, the switch switches the conduction of the two touch units 130 through the switch, and the touch chip 12 determines whether one of the two touch units is conducted or both of the two touch units are conducted according to a signal transmitted by the touch connection.

As can be seen from the above, the number of the touch connection lines 15 can be reduced, and the touch resolution is not affected, so that the display panel is applied to a narrow-frame device or a large-screen device.

In some embodiments, the first conversion circuit 200 comprises a waveform conversion circuit. The shape conversion circuit may be a triangular wave conversion circuit, a sine wave conversion circuit, a sawtooth wave conversion circuit, or the like.

In some embodiments, the first conversion circuit 200 includes a signal strength variation circuit. The signal intensity changing circuit can be an amplifying circuit and a voltage reducing circuit.

Each group of touch units 140 further includes a third touch unit 133 and a second conversion circuit 210, where the third touch unit 133 is connected to the touch connection line 15 through the second conversion circuit 210, so that an original signal input to the second conversion circuit 210 is converted into a second conversion signal, a waveform shape and/or intensity of the second conversion signal is different from that of the first conversion signal, and a waveform shape and/or intensity of the second conversion signal is different from that of the original signal.

In the embodiment of the present invention, when the touch area 100 is actually touched, i.e. when the touch units 130 are triggered by external touch, e.g. by a finger of a user, the touch units 130 are generally touched to a plurality of touch units 130, e.g. three touch units 130 are touched at a time, if the three touch units 130 are different touch units 140, one of the first touch units 131, the other touch unit is the second touch unit 132, and the other touch unit is the third touch unit 133, and an original signal triggered by the first touch unit 131 is directly transmitted to the touch connection line 15 and then transmitted to the touch chip 12. The original signal triggered by the second touch unit 132 is transmitted to the touch connection line 15 through the first conversion circuit 200, which converts the signal transmitted by the second touch unit 132 into a first conversion signal, such as a triangular wave, the waveform shape and/or intensity of the first conversion signal being different from the original signal.
