POLYSILICON THIN FILM AND MANUFACTURING METHOD THEREOF, ARRAY SUBSTRATE AND DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a polysilicon thin film and a manufacturing method thereof, an array substrate and a display device.SOLUTION: The manufacturing method of the polysilicon thin film comprises the steps of: forming a graphene layer and an amorphous silicon layer which are adjacent; and forming polysilicon by crystallizing amorphous silicon so as to obtain the polysilicon thin film. The polysilicon thin film manufactured by the method possesses good characteristics.
