BASF and OSRAM Develop New Highly Efficient White OLEDs

BASF and Osram Opto Semiconductors have developed a highly efficient white OLEDs. The efficiency is over 60 lumens per watt, and meet the international Energy Star SSL standard for color requirements. 

BASF and Osram are conducting research together within the framework of the “OLEDs for Applications on the Lighting Market” (OPAL) project. The OPAL project is being sponsored as part of the OLED Initiative of the German government.

The new OLEDs contain phosphorescent metal complexes as emitter materials and customized complementary materials, which ensure optimum constancy of the color temperatures. The challenge now is to optimize the life of these OLED tiles, especially by stabilizing the blue emitters.
