Abstract: The invention relates to a display screen and a packaging method thereof. The packaging method of the display screen comprises the following steps: providing a substrate of the display screen; evaporating an organic light-emitting material on the substrate; printing a first packaging pattern and a second packaging pattern on the cover plate of the display screen, wherein the first packaging pattern surrounds the second packaging pattern; etching the organic light-emitting material by using a first laser on the substrate; fitting the substrate and the cover plate so that the first packaging pattern and the substrate are fitted, and the second packaging pattern and the organic light-emitting material are fitted; sintering the first packaging pattern and the second packaging pattern by using a second laser on one of the substrate and the cover plate; and performing punching on the display screen.

Abstract: A mask, including a dummy region and at least one effective evaporation region. The at least one effective evaporation region is provided with several first through holes. The dummy region is provided with several second through holes. The second through hole has a same shape as the first through hole, a dimension of the second through hole is equal to a dimension the first through hole, and spacing between the second through holes is equal to spacing between the first through holes. The second through holes are disposed in the dummy region on the outer side of the effective evaporation region. The second through hole has the same shape, dimension, and spacing as the first through hole.

Abstract: An organic light emitting diode pixel arrangement structure includes multiple first sub-pixels, multiple second sub-pixels, and multiple third sub-pixels. Two adjacent first sub-pixels are arranged in a first sub-pixel group, two adjacent second sub-pixels are arranged in a second sub-pixel group, two adjacent third sub-pixels are arranged in a third sub-pixel group. The multiple sub-pixels form multiple arrays, and each array includes at least one first sub-pixel, at least one second sub-pixel and at least one third sub-pixel, each of the first, second and third sub-pixel groups corresponds to a square opening of a mask plate in an evaporation process, there is an inclination angle between a side of the square opening and an arrangement direction of a linear evaporation source, and the inclination angle is an acute angle or an obtuse angle.

Abstract: An OLED pixel arrangement structure includes multiple first sub-pixels, multiple second sub-pixels and multiple third sub-pixels. Four adjacent ones of the first sub-pixels and four adjacent ones of the second sub-pixels are alternately arranged and surround one of the third sub-pixels. Centers of the four adjacent first sub-pixels and centers of the four adjacent second sub-pixels form vertexes of a virtual octagonal cell, and the virtual octagonal cell has at least two orthogonal symmetry axes, a basic pixel unit is formed by the first sub-pixels and the second sub-pixels forming the virtual octagonal cell and a part of the third sub-pixel inside the virtual octagonal cell which are located on one side of one of the at least two orthogonal symmetry axes of the virtual octagonal cell. A center of the third sub-pixel coincides with a center of the virtual octagonal cell.
