Organic light emitting device (oled) pixel arrangement structure

An organic light emitting diode pixel arrangement structure comprising:

• a plurality of first sub-pixels, wherein two adjacent first sub-pixels are arranged in a first sub-pixel group;
• a plurality of second sub-pixels, wherein two adjacent second sub-pixels are arranged in a second sub-pixel group;
• and
• a plurality of third sub-pixels, wherein two adjacent third sub-pixels are arranged in a third sub-pixel group,
• wherein the plurality of first sub-pixels, the plurality of second sub-pixels and the plurality of third sub-pixels form a plurality of arrays, and each of the arrays comprises at least one first sub-pixel, at least one second sub-pixel and at least one third sub-pixel, each of the first sub-pixel group, the second sub-pixel group and the third sub-pixel group 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.
