韩企蓝色磷光OLED材料获新进展

Core Viewpoint - LORDIN has successfully developed the ZETPLEX technology, which addresses the lifespan issues of blue phosphorescent OLED materials and confirms the commercial viability of the product after six years of research [1]. Group 1: Technology Development - The emission layer (EML) in OLEDs is composed of organic materials that emit light when electrified, typically involving a combination of host materials and dopants to produce different colors [4]. - LORDIN's researchers aimed to overcome the limitations of multi-component EML systems, such as difficulty in controlling mixing ratios and high production costs, while addressing the complexities of OLED optical properties [4]. - The ZETPLEX technology features a two-component structure that achieves the efficiency of traditional four-component structures, with external quantum efficiency (EQE) exceeding 20% and device lifespan improved to about 60% of existing phosphorescent blue devices [5]. Group 2: Supply Chain and Production - LORDIN has made progress in establishing an "Indian supply chain" for material localization and stable mass production, ensuring a stable supply of heavy water, a core raw material for high-purity OLED processes [6]. - The company has completed its first supply agreement with an Indian partner and is negotiating a second contract, which would be the largest of its kind among South Korean private enterprises [6]. - This initiative aims to address the instability of raw material supply and ensure price competitiveness [7].
