The present application first proposes a display panel, referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of the display panel of the present application, and as shown in fig. 1, the display panel includes a substrate (not shown), and a plurality of pixel groups 11 disposed on the substrate, and a driving circuit (not shown) disposed on the substrate, the driving circuit being configured to perform light emission control on an organic light emitting device in sub-pixels, each pixel group 11 including a plurality of sub-pixels. Specifically, the driving circuit may be used to provide a corresponding voltage signal, such as an anode voltage signal or a cathode voltage signal, to the anode and/or the cathode in the sub-pixel to control the organic light emitting device to emit light at a desired luminance or to control the organic light emitting device to stop emitting light.
The plurality of pixel groups 11 may include a plurality of rows of pixel groups 11, and for example, in a partial structure of the display panel shown in fig. 1, there are 4 rows of pixel groups 11.

It should be noted that, by disposing the anode via hole X in the corresponding display area, compared with disposing the anode via hole X outside the corresponding display area, the anode can be directly connected to the driving circuit through the anode via hole X, without disposing a corresponding anode trace connected to the anode to extend from inside the display area to outside the display area so as to connect the anode and the anode via hole, and then connecting the anode via hole X to the driving circuit through the anode trace.
In addition, by arranging the anode via holes X of all the sub-pixels in the target pixel unit at the geometric center of the corresponding display area, the diffraction interference phenomenon caused by the arrangement of the anode via holes X in the display area in the sub-pixels can be reduced, so that the negative influence caused by the arrangement of the anode via holes X in the display area in the sub-pixels can be reduced to the minimum, and the symmetry of the sub-pixels can be improved due to the arrangement of the anode via holes X in the geometric center of the regular pattern, so that the negative influence of the color cast phenomenon caused by the asymmetry of the sub-pixels in the sub-pixels can be reduced to the minimum.

Further, the length of the overlapping portion of the pixel group 11 of one row of pixels in the two adjacent rows of pixel groups 11 and the pixel group 11 of the other row of pixels in the two adjacent rows of pixel groups 11 in the first direction D1 is a preset number multiple of the length of the pixel group 11 in the first direction D1, and the preset number is greater than 0 and less than 1.
Specifically, as shown in fig. 1 to 3, the preset number is 0.5, that is, a pixel group 11 in the first row of pixels overlaps a pixel group 11 in the second row of pixels, in a half portion in the second direction D2.
The preset number may be 0.5, 0.3, 0.7, and any other value greater than 0 and less than 1, which is not limited herein.
Alternatively, one pixel group 11 of one row of pixels in the two adjacent rows of pixel groups 11 is overlapped with one pixel group 11 of the other row of pixels in the two adjacent rows of pixel groups 11 in the second direction D2.

In an embodiment, the pixel units other than the target pixel unit among the first, second and third pixel units 111, 112 and 113 include only one sub-pixel.
Only one pixel unit among the first, second and third pixel units 111, 112 and 113 is a target pixel unit, and the pixel units other than the target pixel unit among the first, second and third pixel units 111, 112 and 113 are non-target pixel units.
One pixel group of one row of pixels in the two adjacent rows of pixel groups is partially overlapped with one pixel group of the other row of pixels in the two adjacent rows of pixel groups in the second direction.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a further embodiment of the display panel of the present application, and as shown in fig. 4, the display panel includes a plurality of driving circuits (not shown) and a plurality of data lines sequentially arranged along a first direction, and the plurality of data lines are divided into a plurality of first data lines and a plurality of second data lines.
The first data line is respectively connected with the pixel circuit of each sub-pixel in the corresponding target pixel unit, and the second data line is respectively connected with the pixel circuit of each sub-pixel in the corresponding non-target pixel unit.

Based on the above manner, when the sub-pixels in the target pixel unit are all green sub-pixels, the data lines for providing the data signals for the green sub-pixels are only connected with the green sub-pixels, so that the number of the data lines is as small as possible, the wiring complexity is reduced, and the aperture ratio of the display panel is further improved.
In an embodiment, the sub-pixel further comprises a support layer.
The projection of the cross-section of at least one anode via X onto the display area at least partially overlaps with the projection of the support layer of the corresponding sub-pixel onto the display area.
In particular, the support layer may particularly refer to a PS layer.
The support layer and the pixel via holes are positioned on different layers in the sub-pixel, and the projection of the support layer on the display area is overlapped with the projection part or the whole of the cross section of the anode via hole X on the display area, so that the support layer is also positioned at or near the geometric center of the display area of the sub-pixel, and the part, which is respectively shielded by the support layer and the pixel via hole, is at least partially overlapped in the display area.
In the conventional art, the supporting layer is usually disposed between the adjacent rows of the pixel groups 11 or between the adjacent sub-pixels of the same row of the pixel groups 11, in which case, due to a certain distance between each supporting column and the center of the display area of the corresponding sub-pixel, a certain color shift phenomenon may occur in the display of the sub-pixels.
Based on the above-mentioned mode that makes the projection of supporting layer and the projection of positive pole via hole X overlap at least partially, compare in the prior art that the projection on the display area that supporting layer and pixel via hole correspond respectively does not overlap at all, can be in weakening the colour cast phenomenon of display panel, improve display panel's display effect.
In addition, when the projection of the cross section of at least one anode via hole X on the display area is at least partially overlapped with the projection of the support layer of the corresponding sub-pixel on the display area, if the anode via hole X is still positioned at the geometric center of the corresponding display area, the negative influence of the support layer on the sub-pixel display can be reduced, and the display effect of the display panel is further improved.
Optionally, the projection of the at least one support layer onto the display area of the respective sub-pixel overlaps the geometric center of the display area of the respective sub-pixel.
Specifically, based on the above manner, the distance between the projection of the support layer on the display area and the geometric center of the display area can be reduced as much as possible, so that the color cast phenomenon caused by the relative distance between the support layer and the geometric center of the sub-pixel is reduced or eliminated, and the display effect of the display panel is improved.
Further, the projection of the at least one support layer onto the display area of the respective sub-pixel completely covers the projection of the cross section of the anode via X onto the display area of the respective sub-pixel.
Alternatively, the projection of the cross-section of the anode via X onto the display area completely covers the projection of the support layer onto the display area.
Specifically, based on the above manner, the area of the overlapping portion between the projection of the support layer on the display area of the corresponding sub-pixel and the projection of the cross section of the anode via X on the display area of the corresponding sub-pixel can be maximized, the color cast phenomenon can be reduced as much as possible, and the display effect of the display panel can be improved.
