Of course the first switching transistor and the second switching transistor may be transistors of opposite polarity.
In a specific implementation, the first switching transistor and the second switching transistor may be thin film transistors or metal semiconductor field effect transistors.
Optionally, the data line and the first connection lead are disposed in the same layer.
Optionally, the peripheral region adjacent to the display region in the first direction further includes: a second connecting lead extending in a second direction; the first connecting lead is electrically connected with the second data line through the second connecting lead.
In specific implementation, in the peripheral area of the side of the first sub-data line away from the opening area, the first connecting lead is electrically connected with the first sub-data line through the second connecting lead. When the first connecting lead wire needs to be electrically connected with the second sub-data wire, the first connecting lead wire is electrically connected with the second sub-data wire through the second connecting lead wire in the peripheral area on one side of the second sub-data wire, which is far away from the opening area. For the scheme that the first connecting lead is electrically connected with the switch, in the peripheral area of one side of the second sub data line, which is far away from the opening area, the first connecting lead is electrically connected with the first switch transistor through the second connecting lead.

In fig. 1 to 3, the lengths of the second connecting leads close to the display area and the second connecting leads far from the display area in the peripheral area on the same side of the display area are different for illustration. Of course, in practical implementation, the lengths of the second connection leads in the peripheral region located on the same side of the display region may also be the same.

In a specific implementation, the lengths of the second connecting leads are equal in the peripheral area on the same side of the display area, so that the first leads connected with the second connecting leads and the second data lines are prevented from being loaded consistently, and display difference is avoided.
In specific implementation, when the lengths of the second connecting leads are equal, in a direction perpendicular to the plane where the display panel is located, the orthographic projections of the second connecting leads and the first connecting leads or the first sub-data lines which are not electrically connected with the second connecting leads are overlapped, so that the second connecting leads, the first connecting leads and the data lines are located in different layers to ensure normal transmission of data signals.
In practical implementation, as shown in fig. 5, when the first connection lead and the second sub-data line are electrically connected to different data signal input terminals, the second connection lead 9 is only located in the peripheral region 2 on the side of the first sub-data line 7 away from the aperture region 3, and the lengths of the second connection lead 9 in the peripheral region are all the same.
In practical implementation, as shown in fig. 6, when the first connecting lead 4 is electrically connected to the second sub data line 8 through the second connecting lead 9, optionally, the lengths of the second connecting leads 9 in the peripheral area 2 located on different sides of the display area 1 are equal.
In practical implementation, as shown in fig. 7, when the first connection lead 4 is electrically connected to the first switching transistor Mux1 through the second connection lead 9, the lengths of the second connection leads 9 in the peripheral region 2 on the same side of the display region 1 are equal, and the length of the second connection lead 9 in the peripheral region 2 on the side of the first sub-data line 7 away from the aperture region 3 is greater than the length of the second connection lead 9 in the peripheral region 2 on the side of the second sub-data line 8 away from the aperture region 3.
In a specific implementation, when the lengths of the second connection leads in the peripheral region located on the same side of the display region are equal, optionally, the second connection leads are disposed in the same layer.
In a specific implementation, when the lengths of the second connecting leads are equal in the peripheral region located on the same side of the display region, the second connecting leads may also be located on different film layers.
Alternatively, as shown in fig. 8, in the peripheral area 2 located on the same side of the display area 2 in the first direction Y, different second connecting leads 9 with overlapping projections in the first direction Y are located in different film layers, and different second connecting leads 9 with overlapping projections in the first direction Y have overlapping projections in a direction perpendicular to the plane of the display panel.
