In the above-mentioned pixel arrangement structure, organic light-emitting display panel, high-precision metal mask and display device provided by the embodiment of the present invention, in the pixel arrangement structure: the first sub-pixel is located at the center of the first virtual rectangle and the second The four vertices of a virtual rectangle; the second sub-pixel is located at the center of the side of the first virtual rectangle; the shape of the third sub-pixel is a concave polygon or a figure composed of curves and is located in the second virtual rectangle, The second virtual rectangle is composed of two second sub-pixels located at the center positions of two adjacent sides of the first virtual rectangle, adjacent to the two second sub-pixels and respectively located at the center positions of the first virtual rectangle and The first sub-pixels at a corner position of the first virtual rectangle are sequentially connected as corners to form a first virtual rectangle, and four second virtual rectangles form a first virtual rectangle. Compared with the existing pixel arrangement structure, this pixel arrangement method can make the first sub-pixel, the second sub-pixel and the third sub-pixel be closely arranged under the same process conditions, and the distance between adjacent pixels can be reduced as much as possible. The spacing between them can increase the pixel opening area under the same resolution condition, reduce the driving current of the display device, and increase the life of the display device.

Obviously, those skilled in the art can make various changes and modifications to the utility model without departing from the spirit and scope of the utility model. In this way, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and equivalent technologies thereof, the utility model is also intended to include these modifications and variations.
