The invention relates to the technical field of film preparation, and discloses an inkjet printing method and equipment, and a method for manufacturing a display substrate. The inkjet printing device includes a first nozzle and a second nozzle, through which a solution is inkjet printed on a display area of ​​a display substrate through the first nozzle, the solution is prepared by dissolving a film-forming material in a first solvent, and through the second nozzle The second nozzle inkjet prints the second solvent in the peripheral area outside the display area. When the first solvent in the solution is evaporated to form a thin film, the second solvent will also be evaporated, so that the atmosphere concentration in the display area and the peripheral area is roughly the same. The volatilization speed of the solvent on the substrate is approximately the same, so that the film thickness of the formed film is uniform. Since the second solvent will be evaporated, it will not affect the manufacturing process of the display substrate. Since it is no longer necessary to increase the printing area, it is possible to achieve a narrow frame while ensuring a uniform film thickness to form a thin film.
