摘要：

This paper proposes a novel method to control the emission spectrum of the white organic light-emitting devices (WOLEDs) and improve the device efficiency, which uses Al/Ag as an interconnect layer of the stacked WOLEDs. When the interconnection layer decreases to 5 nm from 9 nm, the Commission Internationale de I'Eclairage coordinates change to (0.38, 0.31) from (0.27, 0.29) within the white-light region. Moreover, we have successfully achieved the complementary WOLEDs (blue and orange) with the desired color temperature (CT), which varies from 8009 K to 4539 K, demonstrating that the CT can be regulated by individual cells. Finally, the paper discusses the optical-electrical characteristics of CT-controllable RGB WOLEDs based on individually addressable method.
