White Top-Emitting OLEDs

DRESDEN, Germany, June 4, 2010 — Novaled GmbH has introduced white top-emitting organic light-emitting diodes (OLEDs) with a lifetime exceeding 50,000 h and a power efficiency of 30 lm/W at an initial luminance of 1000 cd/m2.

The white top-emitting OLED structure is made on metal substrates. Metal substrates bring advantages such as good heat dissipation, mechanical stability and bended designs, and they enable low-cost roll-to-roll production.

The devices were developed using proprietary PIN OLED technology with the company’s doping and host materials in association with a blue flourescent emitting material from SFC Korea.

They have an indium tin oxide-free top contact and incorporate a proprietary light extraction material layer to enhance efficiency. This outcoupling material reduces the color shift over a wide viewing angle so that it can hardly be detected by the naked eye.

The devices’ long lifetime translates into continuous operation for more than 5 years. Using the company’s doping technology, the devices reach a high power efficiency of 30 lm/W measured in an integrating sphere. A broad emission spectrum and good CIE color coordinates (0.46/0.42) render them close to illuminant A and inside the US Department of Energy quadrangles.
