Nippon Electric Glass has reached an agreement with Saint-Gobain to launch a joint venture to develop, manufacture and sell glass substrates with an IEL (Internal Extraction Layer) for organic light emitting diode (OLED) lighting.

To spread the use of OLED lighting, further improvement of luminous efficiency (light extraction efficiency) is a crucial task.

By combining Saint-Gobain basic research capabilities in this field with NEG’s technology, know-how and knowledge in glass composition/manufacturing process development, the joint venture will manufacture and provide the world market with high-performance IEL-equipped glass substrates.

NEG has already developed several kinds of substrates for OLED lighting, including G-Leaf ultra-thin glass and HX-1 high refractive index glass. It is currently proceeding with sample operations. In partnership with the Saint-Gobain, NEG will offer solutions with its glass products in the OLED lighting market, which has high growth potential, aiming to expand its business into the field of next-generation lighting.

An Internal Expraction Layer is a layer formed on a substrate to extract to outside the light generated in OLED layers. It contributes to the luminous efficiency of an OLED.
