Improvement of Electroluminescence Performance of Organic Light-Emitting Diodes with a Liquid-Emitting Layer by Introduction of Electrolyte and a Hole-Blocking Layer

摘要

Research on organic light-emitting diodes (OLEDs) containing solid state organic semiconductors has advanced significantly in the past twenty years, resulting in indispensible technology for flat panel displays and lighting applications. This is because OLEDs exhibit not only high-performance light-emitting charac-teristics but also provide unique benefits such as light weight and flexibility, which are difficult to realize using inorganic LEDs. Taking into account the advantages of organic materials, we developed a unique OLED containing a neat liquid semiconductor, i.e., a liquid OLED that can be used for lighting and display applications.
