Efficient Organic LEDs Demonstrated

Organic light-emitting diodes (OLEDs) are a new type of LED where a thin film of organic compounds is used to produce electroluminescence.

This means that OLEDs can produce paper-thin lights and displays — even foldable ones.

They are, however, still in the early stages of development, so their reliability and energy efficiency needs works. But recently, a company called ODC demonstrated an OLED light that comes close to Energy Star standards.

Specifically, UDC reported data for a series of white PHOLEDs that span a range of white colors that were designed to satisfy the requirements of differing lighting applications. These research results range from warm to cool white with varied power efficacies of 54 to 102 lumens per watt (lm/W). Depending on the specific designs employed, the color rendering indices (CRI’s) varied from 70 to 88, and lifetimes varied from 4,000 to 17,000 hours (to 70% of initial luminance at 1,000 nits*).
