Claim:
1. A method for manufacturing an assembly of a flexible display device, comprising the following steps: (1) providing a flexible base; (2) forming a thermal dissipation layer comprising a graphene layer on the flexible base; (3) forming a protective layer on the graphene layer, wherein the protective layer comprises a stack of a silicon nitride layer and a silicon oxide layer, and the silicon oxide layer has a thickness of 500 nm; and (4) forming an amorphous silicon layer on the protective layer and subjecting the amorphous silicon layer to annealing, doping, and laser activation so as to form a low-temperature polysilicon layer on the protective layer, wherein laser activation generates heat that is at least partly dissipated away through the thermal dissipation layer comprising the graphene layer.
