## Abstract

A mask module includes a framework and a first strip plate fixed on the framework and extending along a first direction. The first strip plate is provided with a first concave-convex structure on one side edge along the first direction. At least one convex structure is provided in a middle of the first concave-convex structure along the first direction. The convex structure and the first stripe plate are integrally formed.
