In the display panel provided by the application, in the same virtual quadrangle 28, the distance from the first sub-pixel 11 to the third sub-pixel 13 at the vertex of the first virtual square 20 is larger than the distance from the third sub-pixel 13 to the other first sub-pixel 11.
In the present embodiment, referring to fig. 1 to 3, the pitches between the third sub-pixel 13 located in the virtual quadrangle 28 and the two first sub-pixels 11 located at the vertices of the virtual quadrangle 28 are different. Specifically, the third sub-pixel 13 is spaced from the first sub-pixel 11 at the vertex of the first virtual square 20 more than the third sub-pixel 13 is spaced from the first sub-pixel 11 at the center 21 of the first virtual square. In some embodiments, the third sub-pixel 13 is located on one side, close to the center 21 of the first virtual square, on the middle line where the two first sub-pixels 11 are connected, so that the distance between the third sub-pixel 13 and the first sub-pixel 11 located at the vertex of the first virtual square 20 is further increased, the stealing of sub-pixels is reduced, and the display effect is improved.
In some embodiments, in the same virtual quadrangle 28, the pitch of the third sub-pixel 13 to the center 21 of the first virtual square is equal to half the pitch of the two first sub-pixels 11.

In this embodiment, referring to fig. 3, the virtual quadrangle 28 is a general quadrangle, and the virtual quadrangle 28 has one right angle shared with the first virtual square 20 and a second right angle formed by the two second sub-pixels 12 and the center 21 of the first virtual square.
In the display panel provided by the application, in the same repeated light emitting unit, the second sub-pixel 12 forms a virtual square, and the third sub-pixel 13 forms a virtual square.
In this embodiment, referring to fig. 1 to 3, in the same repeated light emitting unit, the second sub-pixels 12 form a virtual square, so that the distances between two adjacent second sub-pixels 12 are equal, and the display effect of the display panel is improved.

Alternatively, the virtual square formed by the second sub-pixel 12 and the virtual square formed by the third sub-pixel 13 have the same center as the first virtual square 20. Therefore, the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 are uniformly distributed, and the display effect of the display panel is improved.
In the display panel provided by the application, in the same repeated light emitting unit, the minimum included angle between the connecting line of the two second sub-pixels 12 on opposite sides of the first virtual square 20 and the central line of the first square is a first included angle a, and the range of the first included angle a is greater than or equal to 0 degree and less than or equal to 10 degrees.
In this embodiment, in the same repeated light emitting unit, the minimum included angle between the connecting line of the two second sub-pixels 12 located on opposite sides of the first virtual square 20 and the first center line 22 or the second center line 23 is the first included angle a. Referring to fig. 1 and 2, when the first angle a is 0 degrees, the connecting lines of the two second sub-pixels 12 overlap with the first center line 22 or the second center line 23. At this time, the virtual quadrangle 28 is square.
Alternatively, referring to fig. 3, in the same repeated light emitting unit, when the first included angle a is greater than 0 degrees, the connecting lines of the two second sub-pixels 12 located on opposite sides of the first virtual square 20 are not overlapped with the first central line 22 or the second central line 23, and the virtual quadrangle 28 is a general quadrangle.
In the display panel provided by the application, in the same virtual quadrangle 28, the minimum included angle formed by the connection line of the two first sub-pixels 11 and the connection line of the third sub-pixel 13 and the center 21 of the first virtual square is a second included angle B, and the range of the second included angle B is more than 0 degrees and less than or equal to 10 degrees.
In the present embodiment, in the same virtual quadrangle 28, the minimum included angle formed by the connection line of the two first sub-pixels 11 and the connection line of the third sub-pixel 13 and the center 21 of the first virtual square is the second included angle B. Referring to fig. 1 and 2, the third sub-pixel 13 is located at any side of the connection line of the two first sub-pixels 11. In some embodiments, the second included angle B ranges from greater than 0 degrees to less than 10 degrees. Therefore, the distance difference between the third sub-pixel 13 and other adjacent sub-pixels is smaller, the sub-pixels are uniformly distributed, and the display panel effect is improved.
In the high-resolution OLED display panel, the space between adjacent pixels is small, which results in limited preparation space for supporting the support columns of the mask in the evaporation process, and thus affects the supporting effect. The application provides the following scheme based on the technical problems.

In the present embodiment, the display panel includes a plurality of repeated light emitting units, and a plurality of repeated light emitting unit arrays are provided, each of the repeated light emitting units including a plurality of first sub-pixels 11, a plurality of second sub-pixels 12, and a plurality of third sub-pixels 13.

Wherein the first pitch H1 of a first sub-pixel 11 to an adjacent second sub-pixel 12 is larger than the second pitch H2 of the first sub-pixel 11 to an adjacent other second sub-pixel 12. Since the first pitch H1 is larger than the second pitch H2, the pitch from the first subpixel 11 to the second subpixel 12 is increased, the preparation space of the support column 14 is increased, and the support effect of the support column 14 is enhanced.
In the present embodiment, the first pitch H1 is larger than the second pitch H2. Each side of the first virtual square 20 is divided into two segments by the second sub-pixel 12, wherein one segment with a larger distance corresponds to the first pitch H1, and the other segment corresponds to the second pitch H2.

The first virtual square 20 further comprises two midlines, a first midline 22 and a second midline 23, respectively, which are perpendicular to each other.
