Novaled awarded “Recognized for excellence” by the Eurapean Foundation for Quality Management(EFQM). achieved the highest level with the score of 5 star in the assessment by an independent expert team.
Novaled has announced it has delevoped the world’s most power-efficient white OLED structures, which achieve 36 lumen per Watt(36lm/W). It increased OLED device light emission by more than 80-percent and also improved the angular dependence of the light emitted. Novaled’s efficiency enhancements move OLED technology a step closer to becoming practical for widespread use in lighting applications for the mass market. Novaled will showcase its new technology in Booth #927-4 of the German Pavilion at the Society for Information Display’s (SID) annual International Symposium, Seminar & Exhibition, “Display Week 2011,” May 17-19, 2011, at the Los Angeles Convention Center, Los Angeles; it also will present two papers there on May 20, 2011, on its enhanced outcoupling methods and materials, and on materials for hybrid OLEDs in display applications.
It’s to said that Novaled has overcome both challenges – pioneering a novel way to significantly improve light outcoupling results and boost external quantum efficiency by more than 80 percent, without the costly and time-consuming setup traditionally required for complex manufacturing.
Effective Outcoupling, Better Light Quality
Novaled’s novel methods boost outcoupling effectiveness, substantially increasing the 25-35 percent fraction of generated light. They also increase power efficiency and quantum efficiency in both bottom- and top-emission OLEDs, incorporating the the material NET61 directly inside the electron transport layers and scattering material NLE17 on top of the semi-transparent top electrode to help extract light and improve the quality of light emitted from top-emission white OLED devices.
Novaled uses simple internal outcoupling methods with vacuum evaporation processed organic materials to induce scattering of the light emitted by the OLED. In both bottom- and top-emission OLEDs, the scattering does not negatively impact electrical properties. In addition, Novaled’s new method improves the Color Rendering Index (CRI) value for top-emission OLEDs on metal substrates. Novaled’s demonstrated CRI of 75 for top-emission OLEDs is ample for many commercial lighting applications.
