In some embodiments, the array substrate 10 further includes a touch chip 500. The switching units 200 and the touch connection lines 300 are connected to the touch chip 500.

In some embodiments, the switching unit 200 is disposed between the touch chip 500 and the touch area 100.

In some embodiments, the switching unit 200 includes a switching transistor.

In some embodiments, the touch area 100 is a rectangular area, and the sub-touch areas 101 are sequentially arranged.

In some embodiments, p and q have the same value. In some embodiments, q is also an even number.

In some embodiments, as shown in fig. 14, in the present embodiment, p is 8, and q is 8, that is, the first touch column 1011 in the sub-touch area 101 includes 8 touch units, and the second touch column 1012 also includes 8 touch units.

As shown in fig. 14, the first touch column 1011 includes touch cells a1, a2, A3, a4, a5, A6, a7, and A8 (in the figure, the touch cells A3, a4, a5, and A6 are omitted, and only the touch cells a1, a2, a7, and A8 are shown). The second touch column 1012 includes touch cells B1, B2, B3, B4, B5, B6, B7, and B8 (in the figure, touch cells B3, B4, B5, and B6 are omitted, and only touch cells B1, B2, B7, and B8 are shown).

In the first touch column 1011, a may take values of 1, 3, 5, and 7, where touch units a1 and a2 are connected to the same switch unit, touch units A3 and a4 are connected to the same switch unit, touch units a5 and a6 are connected to the same switch unit, and touch units a7 and A8 are connected to the same switch unit. The switching unit switches at a high frequency (for example, the switching frequency may be 100 MHz). The switching unit drives the a-th touch unit through a first control signal in a first touch time period, and drives the a + 1-th touch unit through a second control signal in a second touch time period. For example, the switching unit may drive the touch units a1, A3, a5, a7 in the first touch period, and drive the touch units a2, a4, a6, A8 in the second touch period.

In the second touch column 1012, B may take values 1 to 8, where the touch cells B1 and B8 are connected to the same touch connection line, the touch cells B2 and B7 are connected to the same touch connection line, the touch cells B3 and B6 are connected to the same touch connection line, and the touch cells B4 and B5 are connected to the same touch connection line.

In some embodiments, as shown in fig. 15, in the first touch column 1011, the switching unit 200 is disposed between two touch units connected to the switching unit 200. For example, the touch units 200 connected to the touch units a1 and a2 are disposed between the touch units a1 and a2, the touch units 200 connected to the touch units A3 and a4 are disposed between the touch units A3 and a4, the touch units 200 connected to the touch units a5 and A6 are disposed between the touch units a5 and A6, and the touch units 200 connected to the touch units a7 and A8 are disposed between the touch units a7 and A8.

In the sub-touch area in the embodiment of the application, different touch units in the first touch column are driven by two different first control signals and second control signals in two different first touch time periods and second touch time periods, and two touch units at different positions in the second touch column are connected to the same touch connecting line, so that when a user touches the array substrate, the electronic device can determine a touch position, that is, a touch position of the user, according to the control signal for driving the touch unit in the first touch column and the position of the touch unit generating an electrical signal in the second touch column. Therefore, the touch function of the electronic equipment can be realized by using fewer touch connecting wires, the size of the display panel of the electronic equipment is reduced, and the cost is reduced.
