摘要：

We have developed novel formulations through a combination of new materials and a co-dopant/co-host systems approach. These novel formulations offer significant improvements in efficiency, lifetime, and color, which are suitable for fabrication of full-color OLED displays. In this report, we will review the progress made at Kodak and compare it with currently available systems.
