Abstract
In this paper, we describe the development of high efficiency deep blue phosphorescent organic light emitting diodes using high triplet energy host and charge transport materials. The quantum efficiency of deep blue phosphorescent organic light-emitting diodes could be improved above 20% by using high triplet energy bipolar host materials, hole transport materials and electron transport materials.
