Inkjet printing method of array substrate, array substrate and display device

An inkjet printing method of an array substrate, wherein the array substrate comprises n kinds of sub-pixels;

• solvent volumes of solutions required for inkjet printing of the n kinds of sub-pixels are different;
• n is a positive integer greater than or equal to 2;
• and the method comprises:
• recording a solvent volume required for inkjet printing of an i-th kind of sub-pixel as Vi, in which i is a positive integer less than or equal to n;
• calculating an Xi value for each kind of the n kinds of sub-pixels, in which Xi=Vi/V1, and V1 refers to a solvent volume required for inkjet printing of a first kind of sub-pixels;
• taking a greatest common divisor of the Xi values of the n kinds of sub-pixels, and recording the greatest common divisor as G;
• and
• dividing the i-th kind of sub-pixel into Xi/G subunits with equal areas, and performing inkjet printing on each of the subunits of the i-th kind of sub-pixel with a solvent volume of V1*G to form a film layer.
