Abstract: A pixel arrangement structure includes two first sub-pixels and two second sub-pixels which are connected as a first virtual quadrilateral. The two first sub-pixels are located at two first vertices of the first virtual quadrilateral. The two second sub-pixels are located at two second vertices of the first virtual quadrilateral. The two first vertices and the two second vertices are alternately arranged and spaced apart from each other. A third sub-pixel is located within the first virtual quadrilateral, and a center of the third sub-pixel deviates from a center of the first virtual quadrilateral. In a row direction or a column direction, the first virtual quadrilateral includes a first side and a second side facing to each other, and a length of the first side is smaller than a length of the second side.

Abstract: The mask includes an evaporation surface and a glass surface facing away from the evaporation surface. The mask is provided with a plurality of evaporation holes distributed in an array. The evaporation hole penetrates the evaporation surface and the glass surface, and the evaporation hole includes a first opening on the evaporation surface and a second opening on the glass surface. An orthographic projection of the first opening on the glass surface is a first projection opening, and the first projection opening covers the second opening. An interval between the first projection opening and the second opening in a first direction of tensioning the mask is a first interval. An interval between the first projection opening and the second opening in a second direction perpendicular to the first direction is a second interval. The second interval is less than the first interval.

Abstract: A mask includes an opening area and a shelter area adjacent to the opening area, the opening area includes an opening pattern, the shelter area includes a buffer pattern adapted to the opening pattern. This application achieves a purpose that a sudden change of stress at a boundary between the opening area and the shelter area is buffered, thereby ensuring that the pull of the mesh as it opens may be smoothly transmitted from the shelter area to the opening area. In addition, this application may also effectively improve meshing accuracy of the mask, thereby improving a yield of vapor deposition products.

Abstract: The present application relates to a display panel and a mask plate for fabricating a display panel. The mask plate for fabricating a display panel includes: a first surface; a second surface opposite to the first surface; and a plurality of through holes spaced apart from each other. The through hole has a first opening formed on the first surface, and a second opening formed on the second surface. An area of the second opening is larger than an area of the first opening. The second openings are arranged in parallel in a first predetermined direction. The first predetermined direction has a predetermined angle with respect to a horizontal direction or a vertical direction of the mask plate, and the predetermined angle does not include 90°.

Abstract: The present disclosure provides a pixel structure, an OLED display screen, and an evaporation mask. The pixel structure includes a plurality of pixel unit groups arranged in an array. Each of the pixel unit groups includes a first sub-pixel, a second sub-pixel and a third sub-pixel. An edge of the first sub-pixel close to the third sub-pixel is not parallel to an edge of the first sub-pixel away from the third sub-pixel. An edge of the second sub-pixel close to the third sub-pixel is not parallel to an edge of the second sub-pixel away from the third sub-pixel. At least two adjacent first sub-pixels and/or at least two adjacent second sub-pixels of at least two adjacent pixel unit groups are formed by a same mask opening in the evaporation mask.
