OLLA project reports OLED lighting milestones

The European OLLA project has demonstrated white OLEDs with an efficacy of 10 lm/W, as well as green ITO-free devices.
Europe's OLLA project, which brings together a consortium of 24 partners to investigate OLEDs for lighting applications, has delivered its first milestone to the European Commission.
The project deliverable is an advanced white OLED prototype light source, with an efficacy of more that 10 lm/W, emitting several thousand hours at 1000 cd/m2 brightness. This initial result makes use of PIN doping technology developed by Novaled, which enables increased efficiency with long lifetime at lower driving voltages.
