The invention belongs to the field of novel display ink-jet printing, and particularly relates to an intelligent circulation ink supply method and device in novel display ink-jet printing manufacturing, and the method comprises the steps: calculating the ratio of the inertia force to the viscous force of current to-be-printed ink in each bent pipe of a circulation ink path, and taking the maximum ratio as a first ratio, calculating the ratio of the cohesive force of the ink to the adhesive force between the ink and the current circulation ink path pipeline material, and taking the ratio as a second ratio; the first ratio and the second ratio are weighted on the basis of evaluation coefficients of two predetermined ratios, if the weighting result meets the value requirement that a cavity is not prone to being generated, the circulation ink path is opened, circulation ink supply is carried out for multiple times, and air in the circulation ink path is exhausted through pressure stabilization regulation and cont
