Abstract

The invention discloses a graphene transparent electrode, a fabrication method thereof and a display device. The fabrication method comprises the following steps of preparing a graphene oxide solution with a predetermined concentration, and carrying out vacuum filtering on the graphene oxide solution after diluted to obtain a graphene oxide thin film; transferring the graphene oxide thin film to a region with an electrode pattern to be formed after filtering, carrying out hot-press spraying and transfer printing; and carrying out reduction treatment on the graphene oxide thin film after hot-press spraying and transfer printing to obtain the graphene transparent electrode. The above fabrication method provided by the embodiment is relatively simple, and the obtained graphene transparent electrode has the advantages of low resistance and high flatness.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a graphene transparent electrode, a manufacturing method thereof and a display device. Background technique [0002] In the field of display technology, flat panel display devices, such as liquid crystal displays and organic electroluminescent displays, occupy an important position in the field of flat panel display technology because of their advantages of lightness, thinness, low power consumption, high brightness, and high image quality. [0003] At present, indium tin oxide (ITO) is generally used as the material of transparent electrodes in display devices. However, due to the poor mechanical stability of ITO and the increasing shortage of indium resources, its cost continues to increase, so it is urgent to find some alternative environmentally friendly electrodes. Material. In the past few decades, researchers have tried a large number of new electrode materials, such as ...
