Polysilicon Thin Film And Manufacturing Method Thereof, Array Substrate And Display Device

摘要

A polysilicon thin film and a manufacturing method thereof, an array substrate and a display device are disclosed. The manufacturing method of the polysilicon thin film comprises the following steps: forming a graphene layer and an amorphous silicon layer which are adjacent; forming polysilicon by way of crystallizing amorphous silicon so as to obtain the polysilicon thin film. The polysilicon thin film manufactured by the method possesses good characteristics.
