Organic light emitting diode display panel and method of fabricating the same

摘要

An organic light emitting diode (OLED) display panel 140 comprises: an organic layer 324 positioned on a first electrode 320; a multilayer thin film 330 is positioned on the organic layer 324, the multilayer thin film 324 being formed of a first plurality of graphene layers and a second plurality of graphene layers, where the first plurality of graphene layers contains interlayer bonding 350 between two or more upper layers thereof. Also disclosed is a method of forming the above OLED display panel 140. The second plurality of graphene layer may not contain any interlayer bonding. The forming of the interlayer bonding 350 may be achieved by performing a hydrogen plasma treatment on the first plurality of graphene layers. The present invention seeks to provide improved moisture resistance in the multilayer film by restricting moisture paths between the graphene particles in the first plurality of graphene layers.
