Abstract
This disclosure provides a mask module, a method for manufacturing a film layer, and a method for manufacturing an organic electromagnetic light-emitting display panel. The mask module is configured to manufacture a display substrate. The display substrate has at least one display area. The display area has at least one island pattern. The mask module includes at least two open type masks. Each of the open type masks has an opening area corresponding to at least one of the display areas. The opening areas of the open type masks corresponding to the same display area are not overlapped with each other, and the open type masks are stitched to constitute a joint and a blocking structure. The joint has a shape as same as that of the display area, and the blocking structure has a shape as same as that of the island pattern.
