White OLEDs with high efficiency and high color stability are developed by using high energy level dopants. The white OLEDs showed high external quantum efficiency of 11.7% and remarkable color stability with the variation of CIE chromaticity coordinates less than (0.02, 0.01) between 10 cd m−2 and 5000 cd m−2. Moreover roll-off of efficiency was low and the CRI value was over 87.
