SDK develops worlds highest light output organic EL

sdk_el.jpgSDK has developed a new structure for its organic electroluminescent (organic EL) devices, achieving approximately 40% in light output, which represents the highest level in the world. As a result, SDK has achieved a 30 lm/W emissive efficiency for its coated phosphorescent-polymer-based organic EL devices. The 30 lm/W emissive efficiency represents the highest level among coated-type organic EL devices that have been announced in the world. SDK organic EL devices with the new structure will be used widely for general lighting applications in the future.

SDK has already achieved a luminance half life of approximately 10,000 hours for white lighting through improvements in the phosphorescent-polymer materials. SDK will continue developing organic EL devices with longer life based on the successful development of the new device structure.
