Abstract

The invention provides a flexible display device and a preparation method thereof. Forming a graphene layer or a graphene oxide layer on a glass substrate by a transfer printing technology; Forming athin film transistor on the graphene layer or the graphene oxide layer; Preparing an organic light emitting device on the thin film transistor; Packaging the thin film transistor and the organic lightemitting device; A glass substrate is removed to obtain the flexible display device. The flexible display device of the invention takes graphene or graphene oxide as a flexible substrate, reduces thethickness of the substrate, realizes the thinning of the flexible display device, and is favorable for simplifying the preparation process of the flexible display device because the graphene or graphene oxide has better flexibility, stability and thermal expansibility.

Description

technical field [0001] The invention relates to the technical field of flexible display, in particular to a flexible display device and a preparation method thereof. Background technique [0002] As a new generation of display devices, flexible displays have a wide range of application prospects in personal digital products, vehicle displays, and military fields due to their advantages of portability, light weight, and unbreakable properties. At present, the main technical difficulty of flexible displays lies in the manufacture of flexible substrates. Existing flexible substrates are relatively thick, and the preparation process is relatively complicated. It is difficult for flexibility and stability to meet the requirements of flexible displays. [0003] Therefore, the prior art needs to be improved. Contents of the invention [0004] In order to solve the above problems, the present invention provides a flexible display device and its preparation method. Graphene or gra...
