▎ 摘  要

NOVELTY - The panel (140) has an organic layer (324) formed between an electrode and a graphene-stacked multilayer thin film. The multilayer thin film is provided with first and second sets of graphene layers (332, 334). An interlayer bonding (350) is provided between the first set of graphene layers. The second set of graphene layers is provided without interlayer bonding. The second set of graphene layers is positioned between the organic layer and the first set of graphene layers. The interlayer bonding includes a diamond-like structure of carbon atoms. USE - Organic LED display panel. ADVANTAGE - The panel has superior light transmittance, sheet resistance, electrical conductivity, mechanical flexibility and reliability characteristics, while reducing number of process steps and time required for processing. The panel has reduced thickness due to omission of traditional upper substrate, so that characteristics e.g. moisture impermeability, electrical conductivity and light transmittance, can are significantly improved and mechanical flexibility due to physical properties of graphene can be obtained, thus reducing manufacturing cost when an electrode layer and an encapsulation layer are simultaneously formed. DETAILED DESCRIPTION - The electrode is a gate electrode (304) or a source electrode/trench electrode (310). An INDEPENDENT CLAIM is also included for a method for fabricating an organic LED display panel. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of an organic LED display panel.
