Novaled zeigt auf der SID-2010 in Washington neue weiß top-emitting Beleuchtungspanels. Diese erreichen eine Lebenszeit von 50.000 Stunden und verbrauchen dabei nur 30lm/Watt bei einer Helligkeit von 1000 cd/m²
Pressemitteilung Novaled:
The white top emitting OLED structure offers the realisation 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.
The device achieves a lifetime above 50,000 h (t50) at an initial brightness of 1,000 cd/m2. This long lifetime translates into continuous device operation for more than 5 years. By using Novaled’s proprietary doping technology, the device reaches a high power efficiency of 30 lm/W measured in an integrating sphere. Broad emission spectrum and good CIE color coordinates (0.46/0.42) were achieved in the devices, which is close to illuminant A and inside the US Department of Energy (DOE) quadrangles.
“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.”
