High-brightness organic light-emitting diodes

The research of high-brightness organic light-emitting diodes,as an important branch of organic light-emitting diodes (OLEDs),makes it possible for achieving high-brightness lighting source and lasing.Heat dissipation and efficiency roll off,as two main factors,affect the brightness of the OLEDs heavily.In this paper,high-brightness OLEDs are obtained by utilizing pulse voltage,small areas and micro-cavity structure to minimize the effect of the two factors.The major advances,ongoing challenges and future p...     

Platinum complexes as phosphorescent emitters in highly efficient organic light-emitting diodes

Applications of platinum complexes as phosphorescent emitters in high efficiency organic light-emitting diodes (OLEDs) were shortly discussed in this paper. Key recent studies on highly efficient blue, green, red and white-phosphorescent OLEDs based on Pt complexes are presented in terms of efficiency and color quality.
