OLED Encapsulation with Quantum Dots for Color Purity

The patent combines the encapsulation function with the quantum dot integration by incorporating quantum dots directly into the organic layers of the encapsulating structure. This merging of functions allows the encapsulating structure to simultaneously protect the OLED and enhance color purity through quantum dot photoluminescence, rather than requiring separate encapsulation and color enhancement components.

The encapsulating structure is designed to serve multiple functions: it provides moisture and oxygen barrier protection while simultaneously acting as a color conversion layer through integrated quantum dots. The organic layers serve both as encapsulation materials and as host matrices for quantum dot dispersion, enabling a single structure to fulfill multiple roles that would traditionally require separate components.

The patent employs organic layers as thin-film encapsulation materials that inherently provide flexibility. These organic layers can be deposited in thin configurations while maintaining the mechanical flexibility needed for flexible display applications, unlike traditional inorganic thin-film encapsulation that often requires thicker layers for adequate barrier performance.

The encapsulating structure uses composite organic layers that combine encapsulation materials with quantum dot dispersions. This composite approach allows the thin films to maintain both the barrier properties needed for encapsulation and the flexibility required for flexible displays, while the quantum dots provide additional color enhancement functionality.
