Abstract
The present invention relates to the field of display technology, and discloses a method for preparing an array substrate, a display panel and an evaporation apparatus. A method for preparing an array substrate comprises: fixing a base substrate to an evaporation stage; attaching a shielding sheet to the base substrate to cover at least a preset area of the base substrate; arranging and aligning an open mask in association with the base substrate; and evaporating to form a evaporation material layer on the base substrate, to which the shielding sheet is attached, with the open mask.
