?As of April 2025, Universal Display Corporation (UDC) has been actively developing blue phosphorescent OLED (PHOLED) materials. While specific LT50 (time to 50% luminance) values for their latest blue PHOLEDs haven't been publicly disclosed, there have been notable advancements and ongoing challenges:?

  • Historical Context: In 2005, UDC announced a sky-blue PHOLED with a lifetime exceeding 15,000 hours at 200 cd/m². ? ir.oled.com+2Photonics+2Phys.org+2

  • Recent Developments: By 2024, reports indicated that UDC's blue PHOLED project was facing technical challenges, particularly in achieving a long-lasting emitter at the desired color point. This has led to delays in commercial introduction. ? oled-info.com+1ir.oled.com+1

  • Collaborative Research: The University of Michigan, in partnership with UDC and the University of Southern California, has been developing strategies to enhance blue PHOLED lifetimes. Their approach aims to improve lifetimes to over 50,000 hours, a significant increase from previously reported lifetimes of approximately 10,000 hours. ? Energy.gov+1University of Michigan News+1

Given the dynamic nature of OLED research and development, it's advisable to consult UDC's official communications or recent industry publications for the most up-to-date and precise LT50 values for their blue PHOLED materials.
