Core Viewpoint - A new technology developed by KISTI significantly extends the lifespan of blue phosphorescent OLED materials without altering their emission color, potentially reducing power consumption and increasing the longevity of display devices [1][6]. Group 1: Technology Development - KISTI's research team identified that the breaking of specific chemical bonds within the molecules is the main reason for the reduced lifespan of blue phosphorescent OLED materials [1]. - The team proposed an innovative molecular design principle that selectively strengthens these critical chemical bonds while maintaining the emission color [1][6]. - Through the use of supercomputers, the team analyzed over a hundred molecular structures and successfully identified six new candidate luminescent materials [1]. Group 2: Industry Context - The lifespan issue of blue OLEDs has been a long-standing challenge in the display industry, with current commercial products primarily relying on first-generation fluorescent materials that have lower efficiency [6]. - In contrast, red and green OLED materials have already transitioned to the second generation of phosphorescent technology, which is mature and widely commercially applied [6]. - The blue phosphorescent materials and third-generation TADF (thermally activated delayed fluorescence) materials are still in the critical phase of overcoming lifespan and stability challenges [6].
