Moreover, setting the third sub-pixel 03 in a strip shape is beneficial to enlarging the area of the second sub-pixel 02 , so that sub-pixels with low luminous efficiency in the display panel can be set as the second sub-pixel 02 . In addition, the two ends of the strips are designed symmetrically, which can reduce the pattern complexity of the evaporation mask, thereby simplifying the patterning process.

In this way, as shown in FIG. 2 , the green sub-pixel G located in the second virtual rectangle can form a light-emitting pixel point with the red sub-pixel R and the blue sub-pixel B located at any two adjacent corners of the second virtual rectangle.

Furthermore, since the luminous efficiency of the blue sub-pixel is relatively low and its lifespan is relatively short, therefore, optionally, in the pixel arrangement structure provided by the embodiment of the present invention, as shown in FIG. 2 , the first sub-pixel 01 is the red sub-pixel R, the second sub-pixel 02 is the blue sub-pixel B, and the third sub-pixel 03 is the green sub-pixel G; such a striped green sub-pixel G can make the area of the blue sub-pixel B smaller than that of the green sub-pixel The direction of G is extended, so that the area of the blue sub-pixel B is larger than the area of the red sub-pixel R and the area of the green sub-pixel G respectively.

Optionally, in the pixel arrangement structure provided by the embodiment of the present invention, in order to make the third sub-pixel 03 evenly distributed in the pixel arrangement structure, to reduce the distance between the third sub-pixel 03 and the adjacent first sub-pixel The distance between the pixels 01 and the distance between the third sub-pixel 03 and the adjacent second sub-pixel 02 are reduced.

When a high-precision metal mask (FMM) is used to form a sub-pixel pattern with an etching process, the minimum pitch is about 16 μm. When sub-pixel patterns are formed by processes such as laser or electroforming, the minimum pitch will be even smaller.
