Novaled (Dresden, Germany) has demonstrated white, top-emitting OLED devices with a lifetime that exceeds 50,000 hours and a power efficiency of 30lm/W at an initial luminance of 1,000 cd/sq. meter. The high-performance, white, top-emitting OLEDs use the Novaled PIN OLED® technology, with its proprietary doping, and host materials in association with a blue flourescent emitting material from SFC Korea. The device has an ITO-free, top contact and incorporates a Novaled-specific, light-extraction material layer to enhance the efficiency. The outcoupling material reduces the color shift over a wide viewing angle so that it’s barely detectible. The technology also allows the use of metal substrates in conjunction with the OLEDs.
