Curable Silicone Composition for Flexible OLED Encapsulation

The patent employs flexible thin film encapsulation layers comprising alternating inorganic barrier layers and organic buffer layers. The inorganic layers provide moisture and oxygen barrier properties, while the organic layers provide flexibility and stress relief, resolving the contradiction between barrier performance and device flexibility.

The encapsulation structure uses composite materials combining inorganic substances (such as silicon oxide, silicon nitride) for barrier properties with organic substances (such as polymers) for flexibility. This composite approach allows simultaneous achievement of both moisture/oxygen barrier performance and device flexibility.

The encapsulation system is segmented into multiple thin alternating layers of inorganic and organic materials. Each layer is relatively thin and serves a specific function, allowing the complex barrier function to be achieved through simple repetitive deposition processes rather than requiring complex monolithic structures.

By using thin film technology with alternating inorganic and organic layers, the patent achieves effective barrier properties through multiple thin layers that can be deposited using standard semiconductor manufacturing techniques, reducing manufacturing complexity compared to thicker or more complex encapsulation structures.

The thin film encapsulation structure can be directly deposited onto the substrate using vapor deposition techniques, eliminating the need for separate glass lids and epoxy glue application processes. This integration simplifies manufacturing steps, reduces material costs, and improves processing ease while maintaining barrier performance.

The patent merges the encapsulation function directly into the device structure through thin film deposition, combining what were previously separate components (glass lid, epoxy adhesive, barrier layer) into an integrated thin film encapsulation system, thereby reducing manufacturing steps and cost.
