Novaled, a leading company in OLEDs for display and lighting applications, demonstrates white top-emitting devices with a lifetime exceeding 50,000 h and a power efficiency of 30 lm/W at an initial luminance of 1,000 cd/m2.
The white top emitting OLED structure offers the realization of OLED lighting products made on metal substrates. Metal substrates bring advantages such as good heat dissipation, mechanical stability, bended designs and open the roadmap towards low cost roll-to-roll production.
Novaled has developed a high performance white top emitting OLED using the Novaled PIN OLED technology with its proprietary doping and host materials in association with a blue flourescent emitting material from SFC Korea. In addition, the device has an ITO-free top contact and corporates a Novaled-specific light extraction material layer to enhance the efficiency. At the same time this outcoupling material reduces the color shift over a wide viewing angle so that it can hardly be detected by the naked eye.
“With this achievement Novaled demonstrates once again the robustness and potential of its PIN technology”, says Gildas Sorin, Novaled CEO. “Configurations like top or bottom, inverted or non-inverted organic structures with various emitting materials and metal electrodes bring the proper high performance for each specific market request in the display and lighting domain.”
