P‐154L: Late‐News Poster: High‐efficacy OLED Panel with High‐mobility Electron Transport Layers for New Lighting Applications

A 70 mm × 80 mm OLED lighting panel with efficacy of 78.6 lm/W at 1000 cd/m2 has been demonstrated. We improved the efficacy of the panel by decreasing driving voltage. We adopted two approaches: optimize device structure by using high-mobility electron transport layers and improve luminous uniformity by embedding metal bus lines.
