Abstract
The present invention provides a flexible organic light-emitting diode (OLED) and a manufacturing method thereof. The flexible OLED comprises: a flexible array substrate; an organic light-emitting diode formed at one side of the flexible array substrate; an alumina layer formed at one side, far away from the flexible array substrate, of the organic light-emitting diode; at least one recombinationwater-oxygen blocked layer formed at one side, far away from the organic light-emitting diode, of the alumina layer, wherein each recombination water-oxygen blocked layer comprises a micafolium and apolymer layer, and the micafolium is located at one side, facing the alumina layer, of the polymer layer; and a polarizer layer having a touch electrode and formed at one side, far away from the alumina layer, of the water-oxygen blocked layer. The flexible organic light-emitting diode and the manufacturing method thereof can satisfy a water-oxygen blocking requirement and cannot increase a visualangle color error phenomenon of an 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...
