Array Substrate Barrier Stack for Water and Oxygen Blocking

The patent applies composite materials by combining inorganic nanoparticle layers (such as Al2O3, SiO2, TiO2, or ZnO nanoparticles) with organic polymer layers (such as polyimide, polycarbonate, or polymethyl methacrylate) to form a multi-layer packaging structure. This composite structure leverages the advantages of both inorganic materials (excellent water and oxygen barrier properties) and organic materials (flexibility and ease of processing), thereby resolving the contradiction between manufacturing simplicity and blocking performance. The inorganic nanoparticle layer provides superior water and oxygen blocking capability, while the organic polymer layer ensures structural integrity and ease of manufacture.

The patent applies segmentation by dividing the packaging structure into distinct functional layers: an inorganic nanoparticle layer for water and oxygen blocking, and an organic polymer layer for structural support and protection. This segmentation allows each layer to be optimized for its specific function, with the inorganic layer providing superior barrier properties and the organic layer providing mechanical strength and flexibility. The layered structure resolves the contradiction by organizing complexity into manageable, functionally-specific segments rather than using a single monolithic structure.

The patent applies parameter changes by modifying the chemical parameters of the nanoparticle surfaces through surface treatment or functionalization. This treatment introduces reactive groups on the nanoparticle surfaces that can form chemical bonds with the organic polymer layer, thereby enhancing interfacial adhesion and overall structure stability. By changing the surface chemistry parameters of the nanoparticles, the patent achieves strong bonding without requiring extremely high manufacturing precision, as the chemical affinity naturally guides the bonding process.
