Abstract :
Multilayer Highly Color-purified-white Organic Light emitting Devices were fabricated via thermal vacuum deposition method by using DPVBi, ADN:DCJTB and Alq3 as blue, red and green emitting layer, respectively . The results showed the CIE coordinate of the device was fixed at (0.33,0.33) and the chroma was close to (0.32,0.33) when the forward bias voltage changed from 5 to 14V. The device had a maximum luminance of 5893 cd/m2 at 14V and maximum luminous efficiency of 2.41 cd/A at 9 V.
