Abstract
The invention provides a flexible organic light emitting device and a manufacturing method thereof, wherein the flexible organic light emitting device comprises: a flexible array substrate; an organic light emitting device layer formed on one side of the flexible array substrate; an aluminum oxide layer formed on the flexible array substrate The organic light-emitting device layer is away from the side of the flexible array substrate; at least one composite water-oxygen barrier layer is formed on the side of the aluminum oxide layer away from the organic light-emitting device layer, and the composite water-oxygen barrier layer includes mica Foil and a polymer layer, the mica foil is located on the side of the polymer layer facing the aluminum oxide layer; and a polarizing layer with touch electrodes formed on the water and oxygen barrier layer facing away from the aluminum oxide layer side. The invention can not only meet the water-oxygen barrier requirement, but also not aggravate the viewing angle deviation phenomenon of the OLED microcavity device.
Description
technical field [0001] The invention relates to the field of OLED panel manufacturing process, in particular to a flexible organic light-emitting device and a manufacturing method thereof. Background technique [0002] Nowadays, flexible electronics and flexible display have become research hotspots in recent years; flexible display electronic products with fixed curved surface, bendable, foldable and even rollable, including flexible thin film transistor liquid crystal display (Flexible TFT-LCD), flexible organic light-emitting Display (Flexible OLED) has gradually become the most promising high-tech industry. Many mobile phone panel manufacturers at home and abroad have invested huge sums of money in relevant research and verification, vying for the technical and commercial opportunities of flexible EL. [0003] To improve the performance of FOLED (Flexible Organic Light Emitting Diode) devices, in addition to improving the flatness and smoothness of the substrate materia...
