Interview with LORDIN

OLEDs WorlA person wearing glasses and a suit AI-generated content may be incorrect.d Summit 2025 brings together the brightest minds in the display industry—from established giants to emerging startups—to chart the course for the future. In anticipation of the event, we had the opportunity to speak with Dr. Oh Hyoung Yun, CEO of LORDIN, about his upcoming presentation. Here are his insights.

Q1: You will be presenting “Tackling the lifetime problem of high-efficiency phosphorescent blue by employing the innovative ZRIET (Zero Radius of Intramolecular Energy Transfer) mechanism.” Could you tell us a bit more about why you chose to tackle this topic?

We chose to tackle the lifetime problem and commercialization issue of high-efficiency phosphorescent blue, because it remains the final major challenge in OLED displays. 
Our proprietary ZREIT (Zero Radius of Intramolecular Energy Transfer) mechanism allows us to significantly enhance efficiency and operational stability, bringing high-performance blue OLEDs closer to commercialization.

Q2: What are the key technical challenges that OLED manufacturers and suppliers need to overcome today?

OLED manufacturers and suppliers still face challenges related to efficiency roll-off at high current densities, long-term operational lifetime, and material stability. Addressing these issues requires both advanced materials and optimized device architectures.

Q3: With increasing demand for sustainability, how is the OLED industry addressing energy efficiency and recycling concerns?

By implementing high-efficiency blue OLEDs, we can reduce the power consumption of OLED displays by approximately 30%. With around 5 billion people worldwide using mobile devices daily, this translates into a substantial global energy savings impact.

Q4: As a Korean company, how do you view Korea’s role in leading OLED innovation on the global stage? And how can global collaboration — between material suppliers, panel makers, and device companies — accelerate OLED adoption?

Korea has long been a leader in OLED innovation, from materials to panel production. Looking ahead, diversifying sources of organic materials is critical, and India plays an increasingly important role in this ecosystem. 
Strengthening collaboration among material suppliers, panel makers, and device companies worldwide—including India—can accelerate technological advancements and broader adoption of OLED displays.
