P‐174: 16.1‐times Elongation of Operation Lifetime in a Blue TTA‐OLED by using New ETL and EML Materials. Issue 1 (2nd June 2017) - Lin, Bo-Yen
Abstract : Elongation of operation lifetime in a blue TTA‐OLED was demonstrated with T90 increasing from 34 to 550 hours at the initial luminance of 2000 nits, corresponding to 16.1‐times improvement, by: 1. incorporation of new ETL material, 2. layer structure optimization, and 3. new EML material and double EML structures.
