Abstract

The invention provides a film packaging method of a stretchable organic photoelectric device. A film packaging structure prepared by the method is provided with a stretchable organic polymer substratewith high water and oxygen obstruction performance, a stretchable organic photoelectric device and an inorganic/organic fused overlapped film packaging layer with high water and oxygen obstruction performance successively from bottom to top, inorganic/organic overlapped films are used in the high water and oxygen obstruction layer, the infiltration time of a precursor of atomic layer deposition in a reaction chamber is controlled, and an inorganic filling material is formed in the surfaces of the stretchable organic polymer substrate and the organic film layer to improve the water and oxygenobstruction performance thereof.

Description

technical field [0001] The invention relates to the field of flexible display technology, in particular to a film packaging method for stretchable organic photoelectric devices. Background technique [0002] For wearable devices and smart clothing, the future requires on-screen properties that can bend and stretch to match our bodies, and this requires ultra-flexible substrates. The flexible and stretchable substrate is generally an organic polymer material, and there are many holes and defects inside. The water vapor and oxygen in the air can easily penetrate the substrate and affect the display performance of the device. Atomic layer deposition is an excellent choice for modifying stretchable substrates due to its excellent three-dimensional conformality, large-area uniformity, sub-monolayer film thickness control, and low growth temperature. [0003] Atomic layer deposition technology is a method that pulses gas-phase precursors into the reaction chamber alternately, and...
