Abstract

The present invention provides a method for manufacturing an assembly of a flexible display device and an assembly of a flexible display device manufactured therewith. The method includes: (1) providing a flexible base ( 22 ); (2) forming a graphene layer ( 24 ) on the flexible base ( 22 ); (3) forming a protective layer ( 26 ) on the graphene layer ( 24 ); (4) forming a low-temperature polysilicon layer ( 28 ) on the protective layer ( 26 ). The method for manufacturing an assembly of a flexible display device and the assembly of the flexible display device manufactured therewith according to the present invention are such that the graphene layer is formed on the flexible base to effectively conduct out heat generated in the process of forming the low-temperature polysilicon layer so as to protect the flexible base from being affected by the heat without increasing the thickness of the protective layer thereby reducing internal stress and facilitating the realization of thinning.
