Specifically, referring to fig. 2, the touch display panel 200 provided in the present embodiment includes a display area 201 and a non-display area 202, where the non-display area 202 surrounds the display area 201, a plurality of sub-pixels 230 arranged in an array are disposed in the display area 201, the sub-pixels 230 in the same row form a sub-pixel row 234, and the sub-pixels in the same column form a sub-pixel column 231; the touch display panel 200 further includes a plurality of gate lines 220 and a plurality of data lines 210, the data lines 210 are arranged along a first direction, the gate lines 220 are arranged along a second direction, the sub-pixels 230 connected to the same data line 210 are electrically connected to different gate lines 220, two sub-pixels 230 connected to the same data line 210 and located in adjacent sub-pixel rows 234 are located in different sub-pixel columns 231, and at least one sub-pixel column 231 is spaced between the two sub-pixel columns 231, as shown in fig. 2, the data line 210 includes a plurality of line segments located between the two adjacent sub-pixel rows 234 and the two adjacent sub-pixel columns 231, that is, the same data line includes data lines located in the two adjacent sub-pixel rows and data lines located in the two adjacent sub-pixel columns, forming the data line 210 in a zigzag shape, and a line segment in the column direction of each data line 210 is electrically connected to the sub-pixel 230 located on the left side of the same data line at the viewing angle shown in fig. 3, the sub-pixels 230 connected to the same data line 210 are arranged in a staggered manner in rows and columns, i.e., the data line is zigzag driven, so that the display image has a double-dot inversion characteristic, which not only reduces power consumption, but also is beneficial to improving the display effect of the display panel.

Therefore, in the present application, the orthographic projection of the same data line 210 on the plane of the substrate is located in the range defined by the orthographic projection of the same touch electrode array 240 on the plane of the substrate, that is, the same data line 210 is covered by the same touch electrode array 240, so that the data line 210 can be prevented from crossing the two touch electrode arrays 240, thereby avoiding the mutual interference between the data line 210 and the touch electrode 241, and being beneficial to improving the image display effect and avoiding the influence on the touch performance.

When the dual-gate structure is adopted, since one data line 210 is electrically connected to the sub-pixels 230 on both sides thereof at the same time, that is, the sub-pixels 230 in the same group in the same row are connected to the same data line 210, and the same data line 210 is connected to the sub-pixels 230 in different pixel groups 232 in two adjacent rows, respectively, in this way, the sub-pixels 230 connected to the same data line 210 are respectively arranged in rows and columns in a staggered manner, and in the same frame time, the polarities of the data signals received by the two sub-pixels 230 in the same row and connected to the same data line 210 are opposite to the polarities of the data signals received by the sub-pixels 230 around the same data line, so that the picture has a double-dot inversion characteristic, which is beneficial to reducing power consumption and improving display effect.

Optionally, with continued reference to fig. 7, the sub-pixel 230 includes a pixel switch 233; the sub-pixel 230 is electrically connected to the gate line 220 and the data line 210 through the pixel switch 233; the switch pixels electrically connected to the sub-pixels 230 in the same row are located at two sides of the sub-pixel row 234, and the pixel switches 233 located at the same side are connected to the same gate line 220.
