The color purity of red emission was improved by controlling the depth distribution of DCM in the Alq/sub 3/ layer. A newly synthesized binuclear metal complex compound was incorporated for blue emission and provided good chromaticity. We found that the rectification property of the OLED is important to drive a passive matrix and about 10/sup 5/ OLED pixels can be driven when aluminum is used as the cathode material. 收起
