Paper Abstract

In past couple of decades, organic EL materials with excellent characteristics have been searched and devices operational stability and efficiency has been significantly improved. However, as an emerging technology for the multibillion-dollar flat-panel-display industry, more typically with continue improvement of liquid crystal displays (LCDs), organic light-emitting diodes (OLEDs) display technology face many challenges. In particular, organic materials for stable and efficient blue EL emission are one of an important subject of these challenges. In this paper, we will review our efforts in developing the organic materials for blue emission of organic electroluminescent devices after reviewing the history of blue EL materials development in past couple decades. Our efforts in developing the organic materials for blue emission of organic electroluminescent devices will include the following: 1. Fused aromatics fluorescent blue EL materials 2. Mixed cyano-isocyanide cyclometalated iridium complex phosphorescent blue EL materials 3. Exploration of the effects of blue emission stability and efficiency.
