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.
