In LED packaging, refractive index modifiers play a crucial role. Acting like an "optical key," they adjust the refractive index of encapsulants to reduce light loss during transmission, thereby improving LED luminous efficiency and brightness.
Take IOTA-9005 Refractive Index Modifier as an example—it features high refractive index, low viscosity, excellent thermal stability, and oxidation resistance, allowing it to blend seamlessly with LED resins, optimize optical matching, and minimize interfacial reflection for higher light extraction efficiency.
With the rise of advanced applications like Mini/Micro LED and automotive LEDs, the demand for precise refractive index control continues to grow. In the future, smarter and more stable refractive index adjustment technologies will further drive the LED industry toward higher efficiency and reliability.
