Abstract
A mask carrier and an evaporation system are provided. The mask carrier includes a base and at least two correction fixtures. The at least two correction fixtures are configured to clamp, on the base, a framework of a metal mask which is used for evaporation on the base, the base has a first opening through which organic material passes, and the at least two correction fixtures are around the first opening in a spaced manner. During organic evaporation coating, the at least two correction fixtures on the mask carrier press the framework of the metal mask to prevent the framework from deformation. Thus, a clearance between a substrate and the metal mask is reduced or even eliminated after the substrate is in press-fit with surface of the metal mask. Patterns obtained through evaporation are clear in shape and outline and normal in size. Hence, the product yield is increased.
