The latest OLED breakthrough, which uses the company's phosphorescent materials, has a power efficacy of 58 lumens per watt and 30,000 hours of operating lifetime, to 70% of initial luminance.
Based in part on the company's new light blue UniversalPHOLED materials system, the device represents a three-fold improvement in operating lifetime over results presented a year ago.
Presentation
Peter Levermore, research scientist at UDC, will present the advances in a paper later today at the conference and will describe two high-performance, all-phosphorescent OLED lighting panels, 15 x 15cm in size.
The lighting devices use advances in OLED panel layout to achieve better uniformity. Combined with the lower operating temperatures afforded by the all-phosphorescent OLED material system, the panels show a marked improvement in lifetimes on previous panels developed by the company.
Concepts
At SID, taking place in Los Angeles, UDC is also exhibiting white OLED lighting panel designs that exploit new design elements. These include transparent and flexible white OLED lighting products. The company hopes the concepts will spark the imaginations of lighting designers.
By 2016, solid-state lighting, including white OLEDs, could generate over €12.4 billion in worldwide savings of electricity costs and could save over 9 million tonnes of carbon emissions from the US.
UDC's R&D is supported and funded in part by the US Department of Energy.
