Paper Abstract

The efficiency improvement of fluorescent blue organic light-emitting diodes were investigated by inserting buffer layer. The OLED device using several buffer materials which have different HOMO and LUMO energy level were evaluated. The inserted buffer layer could control the effective hole injection and electron blocking, which leaded to remarkable high efficiency performance.
